Definitions
- This invention relates to an apparatus and method of printing on demand, binding and trimming a perfect bound soft cover book.
- such soft cover perfect bound books comprise a stacked plurality of text pages (referred to as a book block) having one edge which is referred to as the spine.
- the cover is of a suitable cover stock that is generally thicker (heavier) than the text pages comprising the book block.
- the cover has a front portion that overlies the front of the book block, a back portion that overlies the back of the book block, and a center portion spanning across the spine of the book block.
- a suitable adhesive is applied between the spine of the book block and the inside face of the center portion of the cover.
- the spine of the book block i.e., the edges of the text pages along one edge of the book block
- the spine of the book block is imbedded in the adhesive which, upon curing, securely adheres the pages of the book block to one another and to the center portion of the cover, thereby permitting the book to be opened to any page without the pages coming loose.
- the pages of each book block are usually jogged by specially developed machines prior to the application of adhesive so as to insure that the edges of the pages are properly aligned with one another.
- the adhesive typically a suitable hot melt adhesive
- the cover which is usually preprinted, is then folded around the front, spine, and back of the book block and is firmly clamped to the book block proximate the spine during assembly. In this manner, the adhesive is firmly pressed between the spine of the book block and the inner face of the center portion of the cover to property adhere the cover to the book block while simultaneously adhering the pages to one another.
- Such perfect bound books are printed on pages that are somewhat larger than the desired size (i.e., the length and width) of the finished and bound book to be produced. These books, after they are bound, are typically trimmed along three sides to the desired final dimension in a separate trimming machine.
- Such operations were carried out in separate machines that required considerable adjustment to bind books of different sizes and thus were best suited for production runs of many books.
- both prior art binding machines and trimming machines were very expensive.
- EP-A-0 895 872 there is described an apparatus for the demand printing and binding a perfect bound book, according to the preamble of claim 1.
- a method according to the preamble of claim 6 is also known from EP-A-0 895 872 .

- Such a printing and binding apparatus which incorporates a clamping section that clamps the cover to margins of the front and back of the book block proximate the spine, with the center portion of the cover substantially aligned with the spine of the book, to allow the adhesive to properly adhere the cover to the spine of the book block and to adhere the pages of the book block to one another;
- Such a printing and binding apparatus which includes a trimmer adapted to receive a bound book from the clamping section so as to trim a first edge thereof, to turn the book 90° to trim a second edge thereof, and to turn the book another 90° to trim a third edge thereof;
- Such a printing and binding apparatus and method which accommodates books within a wide range of sizes (for example the width and length of the book ranging between about 12.7x17.8 cm (5 x 7 inches) and about 21.6x27.9 cm (8 1 ⁇ 2 x 11 inches)) and within a wide range of thicknesses (for example ranging from between 0.63 cm (1 ⁇ 4 inch) and approximately 3.81 cm (1 1 ⁇ 2 inches), or ranging between about 25 pages and 1000 pages);
- Such a printing and binding apparatus which, upon receiving data corresponding to the size (i.e., the length and width of the book) and thickness (i.e., the number of pages) of the book to be bound, automatically controls the book page printer to print the pages of the book to be arranged in the book block, automatically controls the cover printer to print the cover of the particular book to be bound, automatically adjusts the clamping section to accommodate such book with the cover properly aligned with respect to the spine of the book block, and properly adjusts the trimmer so as to trim the excess width and height of the bound book to produce a bound book corresponding to the desired size for the finished book;
- Such a printing and binding apparatus which may optionally incorporate a second, book (text) page printer to increase the rate of production of perfect bound books; and the provision of such a printing and binding apparatus which does not require special training for use, which is of economical construction, which has a relatively fast production speed, and which is reliable in operation.
- the printing and binding apparatus of a first embodiment of this invention comprises a book page printer that prints the text pages of the book to be bound and collates the pages to form a book block, and a cover printer that prints the cover of the particular book to be bound.
- the first embodiment of the invention comprises a carriage receiving the book block and movable along a workpath.
- the carriage of the printing and binding apparatus of the first embodiment is configured to hold the book block with the pages of the book block oriented such that the width dimension of the pages of the book block extends vertically and such that a lengthwise edge of the book block is the lowermost horizontal edge of the book block (this lowermost edge being referred to as the spine of the book block).
- the workpath preferably has a jogging station, a milling station, an adhesive application station, a clamping station, and optionally a trimming station located therealong.
- the carriage receives the initially collated pages of the book block from the book page (text page) printer transfer mechanism and loosely holds the loose pages of the book block such that a jogging mechanism may mechanically vibrate the pages so as allow the pages to move relative to one another in a manner such that the edges of the pages constituting the spine of the book block are substantially in the same horizontal plane and such that widthwise edges of the pages are substantially in the same vertical planes.
- the carriage securely grips the jogged pages and transports the book block from the jogging station to the milling station where a suitable tool roughs the lowermost margin of the book block so as to insure that the spine is substantially coplanar and has a good adhering surface.
- the carriage then transports the book block to the adhesive application station where a suitable adhesive is applied to the spine of the book block.
- the cover printer prints a book cover in black and white or color and transfers the book cover to the workpath where it is precisely positioned in the binding station of the apparatus relative to the book block being conveyed along the workpath of the apparatus.
- the cover of the bound book is positioned such that the center portion of the cover is in register with and is substantially aligned with respect to the spine of the book block with the adhesive disposed between the spine of the book block and the inner face of the cover.
- the binding station includes a clamp which engages the cover proximate the spine and forcefully compresses the front and back portions of the cover onto the front and back faces of the book block to thereby adhere the center portion of the cover to the spine of the book block, while simultaneously bonding the pages of the book block to one another with the adhesive bonding.
- the carriage further moves the bound book along the workpath to the trimming station that has a trimming blade capable of trimming the non-spine edges of the bound book.
- the trimming station has a book positioner which positions a first edge of the book to be trimmed in a desired position with respect to the trimming blade such that when the trimming blade is actuated, a predetermined amount of the cover and the book block along this first edge is trimmed from the bound book.
- the trimming station further has a book turning mechanism that turns the bound book 90° such that a second edge of the book to be trimmed faces the trimming blade.
- the book positioner moves the bound book relative to the trimming blade so that upon actuation of the trimming blade, a predetermined amount of the cover and the book block along this second edge is trimmed from the book.
- the book turning mechanism then turns the bound book another 90° such that a third edge of the bound book to be trimmed faces the trimming blade.
- the book positioner moves the bound book relative to the trimming blade so that upon actuation of the trimming blade, a predetermined amount of the cover and the book block along this third edge is trimmed from the book.
- the trimming process produces a perfect bound book trimmed along three edges to a predetermined size.
- a portion of a first embodiment of a printing and binding apparatus of this invention is indicated by reference character 1. Additional component parts of the first embodiment, a book page printer and its book block transfer mechanism, as well as a color cover printer and its cover transfer mechanism are not shown in Fig. 1 in order to provide an unobstructed view of the top of the binding and trimming apparatus.
- the book page printer 110 and its transfer mechanism 112 and the book cover printer 114 and its transfer mechanism or conveyor 116 are shown in their relative positions in Fig. 14 , which is a view of the apparatus similar to Fig. 1 .
- the book page printer 110 is a QMS4032 black and white book body printer and the book cover printer 114 is a QMS330EX color laser printer.
- the book page printer 110 is a QMS4032 black and white book body printer and the book cover printer 114 is a QMS330EX color laser printer.
- the manufacturers of such printers are constantly introducing new models with better performance and capabilities, it will be understood that such newly introduced printers by any manufacturer may be used with or even retrofitted to the on demand book printing, binding and trimming apparatus of the present invention.
- the printers and their transfer mechanisms as shown in the drawings will be described in greater detail below.
- the printing and binding apparatus 1 has a frame 3 made of welded square steel tubes.
- the frame 3 has a pair of spaced horizontal frame rails 3a, 3b extending substantially the length of the apparatus 1.
- a metal cover or shroud SH may be secured to the frame 3 and is shown in Fig. 13 .
- the shroud has been omitted from the other drawing figures for the sake of clarity.
- a conveyor 5 is provided between the frame rails 3a, 3b for transporting or conveying a book block BB along a workpath WP, as will be described hereinafter.
- the conveyor 5 includes a carriage 7 movable in a horizontal direction on carriage wheels CW which bear on carriage rails 8a, 8b that are each mounted to one of the respective frame rails 3a, 3b, as best shown in Fig. 3 .
- the carriage is power driven along the carriage rails by means of a conveyor stepper motor M1 that drives the carriage via a toothed timing belt and pulley arrangement, as indicated at CB.
- a conveyor stepper motor M1 that drives the carriage via a toothed timing belt and pulley arrangement, as indicated at CB.
- the timing belt is attached to one end of the carriage 7 and the belt is trained around a drive pulley on the motor M1 and around other pulleys that are journalled to the frame 3 to the other end of the belt which is attached to the other end of the carriage.
- the conveyor motor M1 is a stepper motor driven by a control system CONT 1, as will be hereinafter described and which is shown in Fig. 12 , so that the position of the carriage (and hence the book block carried thereby) is accurately known (i.e., to within about 0.005 inches) with respect to a reference surface of the carriage 7.
- the position of the book block is accurately known by the control system CONT 1 as the book block is carried along the workpath where it is bound and trimmed, as will be hereinafter discussed in detail.
- the carriage may be accurately stopped at any position or work station along the workpath WP to accurately position the book block at a desired location.
- the motor M1 can be driven in reverse so as to move the carriage 7 in a reverse direction along the conveyor so as to return the carriage to its starting position where it can then receive the next book block to be bound.
- the carriage can be advanced past the trimmer station to a second printing station where the carriage receives a second book block prior to the carriage being driven in reverse to return it to a starting position from which the second book block can be bound and trimmed.
- each book block BB comprises a plurality of pages P, which generally constitute the text pages of a book to be bound.
- the number of pages making up the book block may range between a minimum number and a maximum number of pages, depending on the range of binding thicknesses to be accommodated by the binding and trimming apparatus 1.
- the thickness of the book block BB ranges from about 0.63 cm (1 ⁇ 4 inch) (or less) to about 3.81 cm (1 1 ⁇ 2 inches) (or more). This thickness range may accommodate books from about 25 pages up to about 1000 pages (or more), depending on the thickness of the paper used.
- the minimum thickness of books to be bound by the apparatus 1 is generally dependent on the minimum thickness of the book block capable of being adhesive bound to a cover. Generally, book blocks with less than about 25 pages are not perfect bound, but in theory, a book with even a single page could be bound by other embodiments of the present invention.
- the pages P of the book block BB are duplex printed on both their front and back faces and are rectangular in shape, having a widthwise dimension and a lengthwise dimension.
- the pages may, for example, range between a 12.7x17.8 cm (5x7 inch) rectangular format and a 21.6x27.9 cm (81 ⁇ 2 x 11 inch) rectangular format, or any number of rectangular formats within the above range.
- other formats may be accommodated by adjusting the size of the printing and binding apparatus.
- the printing and binding apparatus 1 of the first embodiment of the present invention automatically accommodates any book size within the ranges of sizes thicknesses (i.e., number of pages), as is discussed below.
- One edge of the book block BB is referred to as the spine S of the book block.
- the spine of the book block corresponds to the lowermost horizontal edge of the book block (which is a lengthwise (major) rectangular dimension of the pages of the book block) when the book block BB is placed in the carriage of the printing and binding apparatus 1, as shown in Figs. 1 and 2 . While the book block BB is shown to have its longest or major dimension (i.e., its length) as the spine of the book to be bound, those skilled in the art will recognize that the shorter (minor) width of the book block may be used as the spine S instead.
- the first book page (text page) printer 110 is integrated into the book printing and binding apparatus 1 adjacent the jogging station JS.
- the book page printer 110 is supported adjacent the apparatus by a support platform 118 that is attached to the tubular frame of the apparatus by a vertically hinged support 120.
- the support is hinged such that the printer can be swung away from its operating position when the printing and binding apparatus requires maintenance.
- the printer platform 118 supports the book page printer 110 at an angled orientation relative to the apparatus.
- the page ejection slot 122 of the printer is positioned adjacent the apparatus 1 where a printed page of a book being printed by the book page printer 110 will be ejected from the printer slot 122 over the apparatus jogging station JS.
- the arrow 124 indicates the direction in which printed pages are ejected from the book page printer slot 122.
- the operation of the book page printer 110, including the pages of the book to be printed, is controlled by the apparatus computer control system CONT 1 with which the book page printer 110 communicates.
- the page transfer mechanism 112 is supported over the jogging station JS by a support panel 128 that projects upwardly from the frame 3 of the apparatus 1 at the left hand end of the apparatus as viewed in Fig. 14 and by a support rod 130 that projects outwardly over the jogging station JS from the printer hinge support 120.
- a shaft 132 is mounted for rotation to the support panel 128 and to the support rod 130 and projects over the jogging station JS. As best seen in Fig. 16 , the shaft 132 is angled slightly such that the end of the shaft closest to the left hand end of the apparatus 1, as viewed in Fig.
- a rectangular collator tray 134 mounted on the shaft 132 for rotation therewith is a rectangular collator tray 134.
- the tray 134 projects out to a position adjacent the page ejection slot 122 of the book page printer 110 where it will receive printed pages ejected from the printer.
- the tray 134 on the shaft 132 angles downwardly away from the book page printer 110 and is also angled downwardly toward the left hand end of the apparatus as shown in Fig. 14 .
- Mounted at the back of the tray 134 is a box shaped bin having first 136 and second 138 side walls, a rear wall 140, and a top wall 142.
- the bin receives pages ejected from the page printer 110 and holds the pages on the tray 134 in the initial formation of the book block.
- a vibrating mechanism 144 is mounted on the second side wall 138 of the bin. Operation of the vibrating mechanism 144, which is controlled by the control system CONT 1, provides an initial jogging and collating of the printed pages of the book block on the tray 134 toward the back wall 140 and the second side wall 138 of the transfer mechanism 112 due to the angled orientation of the shaft 132 and the tray 134 on the shaft.
- a small reversible, direct current clamping mechanism motor 146 mounted on the back wall 140 of the tray 134.
- the clamping mechanism motor 146 is selectively controlled by the control system CONT 1 to rotate a screw shaft 148 of the motor in opposite directions.
- the screw shaft 148 is threaded into a clamping arm 150 at one end of the arm.
- the arm 150 is mounted by a pivot pin 152 connection to the top wall 142 of the tray bin.
- the arm has a clamping pad 154 at an opposite end of the arm from the screw shaft 148.
- Rotation of the screwshaft 148 by the clamping mechanism motor 146 in one direction will cause the arm to pivot about its pivot pin 152, thereby allowing the clamping pad 154 to clamp down on the book block that has been initially collated in the bin of the transfer mechanism 112. Rotation of the screwshaft 148 in the opposite direction will cause the clamping pad 154 to pivot away from the book block, thereby releasing the book block.
- Contact switches (not shown) are mounted on the clamping arm to produce signals that indicate when a book block is clamped securely by the arm and when the arm is moved to a position to release a book block.
- a shaft arm 156 is secured to the transfer tray shaft 132 and projects outwardly a short distance from the shaft.
- An alternating current transfer mechanism motor 158 is mounted to the frame 3 of the apparatus 1 as shown in Figs. 15 and 17 and has a motor arm 160 that is secured to the motor shaft and that projects outwardly from the motor shaft.
- the shaft arm 156 and the motor arm 160 are interconnected by a connecting rod 162 that is mounted to the two arms at its opposite ends by pivot connections. Selective operation of the transfer mechanism motor 158 will cause its shaft, the motor arm 160, and consequently the shaft arm 156 to move through an arc segment which causes the tray 134 to pivot between a printed page receiving position shown in Fig. 15 and a book block depositing position shown in Fig. 17 .
- the motor arm 160 is preferably shorter than the shaft arm 156 such that the tray 134 will move from the page receiving position, to the book block depositing position, and back to the page receiving position simply by rotating the motor arm 160 through a 360° rotation. This allows the transfer mechanism motor 158 to be a simple, non-reversible motor.
- the tray 134 of the book page printer transfer mechanism 112 is first positioned in its page receiving position shown in Fig. 15 by operation of the transfer mechanism motor 160 that is controlled by the control system CONT 1. Pages printed by the book page printer 110 are ejected from the printer slot 122 and are collected on the tray 134. Operation of the bin vibrating mechanism 144 causes the printed pages to be initially jogged and collated as they are collected into the corner of the tray defined by the back wall 140 and the second side wall 138 of the bin. When the entire book block has been printed and initially collated on the tray 134, the clamping mechanism motor 146 is operated causing the clamping arm 150 to close down on the book block with the clamping pad 154 of the arm securely holding the printed book block on the tray.
- the transfer mechanism motor 160 is then operated causing the tray to move to its book block depositing position shown in Fig. 17 .
- the clamping mechanism motor 146 is operated causing the clamping arm 150 to open and release the book block from the tray 134 such that the book block will fall into the carriage 7 that holds the book block during further steps in the printing and binding process of the book.
- each book block BB is adapted to be bound in a suitable book cover C by a binding technique or method referred to as perfect binding.
- books bound by the perfect binding method are soft cover books.
- the book cover C is typically formed of a suitable stock of heavier weight than the pages of the book block BB and may be coated so as to have a superior finish and may be color printed.
- the cover has a front face FC, a back face BC, and a center portion CP therebetween. The width of the center portion CP of the cover C generally corresponds to the thickness of the book block to which it is ultimately attached.
- the pages P of the book block and the cover C are somewhat oversize relative to the desired size of the finished, bound book such that the margins of the bound book can be trimmed to a predetermined size after the book block has been bound to the cover to result in a perfect bound book having the desired size with even edges along the sides or margins (preferably along three sides) of the book.
- the oversize margins of the book block BB and of the cover C are shown as trim margins, TM1-TM3.
- a book having a format of any finished (trimmed) size ranging from between about 12.7x17.8 cm (5 x 7 inches) to just slightly less than 21.6x27.9 cm (8 1 ⁇ 2 x 11 inches) may be printed on conventional 21.6x27.9 cm (8 1 ⁇ 2 x 11 inch) sheet stock.
- the text page printers 110 and 200 will print the text on a selected area of each page such that the text is spaced a predetermined amount from one edge of the page (the spine) and centered along the spine.
- the trim margins TM1 - TM3 will be known to the control system CONT 1 and thus the trim margins may be accurately trimmed from the bound book at the trimming station TS so as to produce a book having uniform edges and having a predetermined finished size.
- the book block BB and cover C may be printed by any method.
- the printing and binding apparatus 1 of the present invention is capable of instant setup for any size or format of book to be bound (i.e., the size of the pages and the thickness of the book) within a predetermined range of book sizes (e.g., from 12.7x17.8 cm (5 x 7 inches) to about 21.6x27.9 cm (8 1 ⁇ 2 x 11 inches), and any combination of rectangular sizes within such range, and in thickness ranging from about 25 pages to about 1000 pages or more), the printing and binding apparatus of the present invention is particularly well-suited to print, bind, and trim a single copy (or a small run quantity) of perfect bound book(s) printed on-demand as described in U. S.
- the on-demand printing apparatus of the present invention can automatically, from the data relating to the size and thickness of the book to be bound, determine (calculate) the width of the center portion CP of the cover C and the width of the trim margins TM1-TM3 so as to bind any size book within the range of book sizes that can be accommodated by the printing and binding apparatus 1 of this invention.
- the second book may be of an entirely different size and thickness than the first book and the printing and binding apparatus 1 will automatically accommodate this second book so long as the second book is also within the range of book sizes that can be accommodated by the printing and binding apparatus.
- the binding process of the printing and binding apparatus has a sufficiently fast operational cycle such that it will finish binding and trimming one book while a second book is being on-demand printed.
- the book cover printer 114 is positioned adjacent the binding station BS of the printing and binding apparatus 1.
- the book cover printer 114 is shown pulled slightly away from the apparatus in Fig. 13 to illustrate how it can be easily separated from the apparatus for servicing.
- the cover printer 114 is shown in its operative position relative to the apparatus in Fig. 14 .
- the cover printer 114 has a slot 166 on the top of the printer where color printed book covers are ejected from the printer.
- Mounted on the top of the cover printer is the cover printer transfer mechanism 116 that projects outwardly from the printer to a position adjacent the binding station BS of the printing and binding apparatus 1.
- the cover transfer mechanism 116 is comprised of a pair of C-shaped channels 168, 170 having openings that mutually oppose each other and extend along the length of the apparatus from positions over the printer 114 to positions adjacent the binding station BS of the apparatus.
- a plurality of cross bars 172 extend between the two channels 168, 170 forming the frame of the cover transfer mechanism 116.
- An additional plurality of bars 174 extend between pairs of the cross bars 172 rigidifying the frame and providing a sliding surface for the cover to be printed by the cover printer 114.
- a pivot rod 176 extends across an intermediate portion of the frame and has a plurality of pawls 178 secured to the rod. The pivot rod 176 is connected to a switch 180 that controls the operation of the cover transfer mechanism 116 as will be explained.
- two pairs of roller shafts 182, 184 are mounted for rotation to the channels 168, 170 of the frame on opposite sides of the pivot rod 176.
- Each of the shafts of the pairs are positioned above and below each other.
- Each of the pairs of shafts 182, 184 has three pairs of mutually contacting rollers 186, 188 mounted to the shafts for rotation with the shafts.
- the upper shafts of each pair are operatively connected together by a chain and sprocket connection 190 shown in Fig. 14 .
- the chain and sprocket connection 190 and the mutual engagement between the roller pairs 186, 188 provide a driving arrangement between the rollers where, when the rollers on the upper shafts rotate in a clockwise direction, the rollers on the lower shafts rotate in a counter clockwise direction and vice versa.
- a reversible motor (not shown) is controlled by the control system CONT 1 and is operatively connected to the chain and sprocket connection 190 to drive the rotation of the upper and lower rollers in opposite directions of rotation.
- the motor (not shown) is also operatively connected with the pivot rod switch 180 to control the motor's direction of rotation, and thus the direction of rotation of the rollers 186, 188.
- the movement of the pawls to their second position activates the pivot rod switch 180, which in turn, controls the motor of the cover transfer mechanism 116 to rotate the upper rollers 186 of each pair of rollers to rotate in the clockwise direction and the lower rollers 188 of each pair of rollers to rotate in the counter clockwise direction as viewed in Fig. 19 .
- the cover being ejected from the cover printer 114 is received between the pairs of rollers shown to the left in Fig. 19 and the rotation of the rollers transports the cover to the left as viewed in Fig. 19 between the opposed pair of channels 168, 170 and over the sliding bars 174 of the transfer mechanism frame.
- the rollers 186, 188 of the transfer mechanism 116 transfer the cover over the clamp members 35a, 35b with an edge of the cover sliding along the positioning pins 36 until the leading edge of the cover comes in contact with the stop switch 196 indicating the proper position of the cover over the center of the binding clamp 38.
- the positioning pins and the stop switch can be eliminated and replaced by a simple bin that is centrally positioned with respect to the binding clamps. In either manner, the cover printer 114 and its associated transfer mechanism 116 automatically operate to provide a color printed cover to the printing and binding apparatus 1 where it is ready to be secured to the book block by the apparatus.
- the book block BB is loaded in the carriage 7 which is movable along the conveyor 5 in a horizontal direction along the workpath WP.
- the carriage 7 is substantially centered on the workpath WP and has a carriage clamping mechanism 9, which is selectively actuated to firmly hold the pages P of the book block relative to one another.
- This clamping mechanism 9 comprises vertical clamping members 11a, 11b which, upon actuation of the clamping mechanism, are preferably self-centering such that the book block BB, regardless of its thickness, is centered with respect to the workpath WP as it is held within the carriage 7.
- the self-centering drive of the clamping members 11 a, 11 b is driven by an electric motor M2.
- the motor M2 drives the clamping members toward each other via a suitable self-centering gear drive (not shown) such that they firmly grip the book block BB and such that when the motor M2 stalls or stops, the clamping members exert a sufficient gripping force on the book block so as to firmly hold the pages relative to one another as the book block is transported to the various stations along the workpath WP during the various operations that are preformed on the book block, as will be hereinafter described.
- the clamping members 11 a, 11 b grip the front and back faces of the book block BB in a manner such that the lower margin adjacent the spine of the book block extends below the clamping members.
- the spine S of the book block preferably extends approximately 2.0 cm. below the clamping members when clamped.
- the carriage 7 and the book block BB carried thereby are shown in a first station, referred to as a jogging station JS, at which location the book block is deposited in the carriage 7, but is not clamped.
- a jogging station JS the pages of the book block are mechanically vibrated or jogged so as to allow the pages to move relative to one another such that the bottom most edges of all of the pages of the book block bear on a horizontal surface 13 and the leading, trailing, and upper edges of the pages are substantially aligned with one another.
- the lower lengthwise dimension of the book block rests on the surface 13 of the jogging station JS.
- the jogging operation is carried out by vibrating the book block in the carriage by an electro-mechanical vibrating mechanism 15 (as shown in Fig. 2 ), which has a vibrating magnetic coil (solenoid) 17 connected to the surface 13 by resilient arms 19.
- the magnetic vibrating coil is energized by a suitable power supply (not shown) under the control of the control system CONT 1.
- the carriage clamp 9 is positioned in such manner as to loosely hold the pages P of the book block in vertical positions relative to one another such that they may move relative to one another during the jogging operation to permit the pages to align with one another.
- the pages of the book block are preferably vibrated in such manner that the pages move rearwardly relative to the carriage 7 such that the trailing edges of the pages of the book block contact a vertical surface 21 of the carriage.
- the vertical surface 21 of the carriage 7 thus provides an accurate reference position for the trailing edge of the book block that is later used to positively position the book block relative to the components of the apparatus as the book block is bound and trimmed.
- Fig. 18 shows the carriage 7 mounted on a vibrating device comprised of an upper angled block 300 and a lower angled block 302 with the vibrating mechanism 304 mounted between the two blocks.
- a vibrating device comprised of an upper angled block 300 and a lower angled block 302 with the vibrating mechanism 304 mounted between the two blocks.
- operation of the mechanism is split into two, perpendicular force components with one component directed upwardly and the other directed horizontally to the left as shown in Fig. 18 .
- operation of the vibrating mechanism 304 will jog and collate the pages of the book block on the bottom surface 13 of the jogging station JS and against the left vertical surface 21 of the station.
- the carriage clamp motor M2 Upon completion of the jogging operation (which may only take a second or so), the carriage clamp motor M2 is energized so at to actuate the clamp 9 to firmly clamp the pages of the book block together and to firmly hold the book block BB in a fixed position relative to the carriage 7 as the carriage is moved along the workpath WP.
- the thickness of the book block BB being bound and the clamping pressure exerted by the clamp members 11a, 11b is accommodated by energizing motor M2 to close the clamp and to allow the motor M2 to stall upon the clamp member firmly engaging the book block and exerting a clamping force thereagainst.
- the control system CONT 1 upon being supplied with the size of the book block and cover of the book being bound, can then calculate the position of the leading edge of the book block relative to the carriage by reference to the vertical carriage surface 21.
- both the trailing and leading edges of the book block can be accurately located relative to each station of the printing and binding apparatus as well as the trimmer as the carriage is moved along the workpath from one station to the next.
- the horizontal plate 13 of the jogging station serves as a reference surface for establishing the elevation of the spine S of the book block as the latter is transported along the workpath WP.
- the carriage 7 is moved along the workpath WP by the stepping motor M1 via the timing belt and pulley arrangement CB such that the position of the carriage (and hence the position of the book block carried thereby) may be accurately controlled at any point along the workpath to an accuracy of within about 0.0127 cm (0.005 inches) or about 0.127 mm.
- the carriage 7 and the book block BB carried thereby are moved by the conveyor 5 from the jogging station JS to a second station along the workpath WP.
- This second station is a milling station MS at which a rotary milling or spine grooving head 23 mills or otherwise removes material from the lowermost edge of each of the pages (i.e., the spine S) of the book block to thereby roughen the surface of the spine to better bond the adhesive to the spine and to insure that the spine is coplanar.
- the milling station MS is provided with a vacuum dust or debris collector 27, driven by a motor M3.
- the inlet opening for the dust collector is shown at 29 in Fig. 9 .
- the milling head 23 is rotary driven by a motor M4 at high speed and has a milling blade 31 (as shown best in Fig. 2 ) which engages the spine of the book block as the latter is conveyed over the milling head by the carriage 7.
- the milling blade 31 is a single blade carried on the rapidly rotating milling head, configured to roughen and cut shallow grooves in the spine as the carriage moves the book block thereover. These grooves hold a supply of adhesive and facilitate the spine of the book block being firmly adhered to the center portion CP of the cover.
- the milling station utilized in the preferred embodiment of the printing and binding apparatus can be commercially acquired from Martin Yale Industries, Inc. of Wabash, Indiana.
- this adhesive application station Downstream of the milling station MS along the workpath WP is next located an adhesive application station AS.
- this adhesive application station includes a hot melt adhesive bath 31 (as shown in Fig. 1 ) in which a quantity of a suitable hot melt adhesive, of the type which is well known in the book binding art, is heated to a liquid state.
- a suitable hot melt adhesive of the type which is well known in the book binding art.
- One such adhesive that has worked well in conjunction with the system and method of this invention is a hot melt adhesive commercially available from Capital Adhesives of Mooresville, Indiana, recommended by the manufacturer for binding books.
- any suitable hot melt or cold melt adhesive may be used in accordance with this invention.
- the adhesive application station AS further has an adhesive applicator roller 33 which is partially immersed in the liquid hot melt adhesive and which is rotary driven by a motor M5 such that the roller picks up a coating of the liquid hot melt adhesive on its cylindrical face.
- the upper portion of roller 33 is positioned to be generally tangent to the spine of the book block BB as the book block is conveyed by the carriage 7 along the workpath WP over the roller 33.
- a quantity of hot melt adhesive is applied to the spine of the book block.
- the roller 33 is rotary driven by the motor M5 at approximately the same speed as that of the carriage 7 moving along the workpath WP so as to pick up molten adhesive from the bath 34 and lay down a substantially continuous coating of the liquid hot melt adhesive on the spine S of the book block as the latter is conveyed over the roller.
- the roller motor M5 is energized and de-energized by a micro-switch (not shown) tripped by movement of the carriage 7 as it approaches and leaves the adhesive station.
- the hot melt bath and roller are commercially available. It should be understood that the bath 31 is provided with suitable heaters so as to heat the adhesive to a desired temperature and is further provided with a thermostat control system to maintain the adhesive in the bath at a desired temperature.
- the book block BB is conveyed by the carriage 7 from the adhesive application station AS to the next work station, which is the binding station BS.
- the binding clamp 35 is provided.
- the binding clamp is preferably of the type that is commercially available.
- the binding clamp includes a pair of self-centering, power operated clamp members 35a, 35b, driven by a motor M6, that are disposed on opposite sides of the book block.
- the clamp members 35a, 35b are driven between their open and closed positions by the motor M6 by means of a suitable gear train (not shown). As shown in Fig. 1 , the clamp members 35a, 35b are in their open position with their inner edges spaced apart a distance sufficient to accommodate the thickness of the book block BB to be bound to a cover C.
- the clamp members 35a, 35b are positioned slightly above the bottom surface of the jogging station JS but below the carriage 7 such that the clamp members are disposed to engage the side faces of the book block below the level of the carriage clamp members 11a, 11b, and just above the level of spine S of the book block.
- one lateral side of the binding clamp is mounted by a hinge to the rail 3a and is selectively movable between a lowered position in which the clamp members 35a, 35b are positioned below the level of the spine S of the book block as the carriage 7 moves the book block (with the adhesive applied to the spine) into position over the binding clamp 35 assembly, and a raised position where the book block spine 5 engages against the binding clamp 38 and is positioned between the clamp members 35a, 35b.
- the clamp members 35a, 35b are provided with cover positioning pins 36 which accurately locate a cover C relative to the book block BB to be bound therein. In this manner, with the cover installed on the clamping members 35a, 35b, the center portion CP of the cover may be disposed over the opening between the clamping members 35a, 35b and positioned substantially centered with respect to the spine of the book block.
- the book block When the carriage 7 with the book block therein is stopped at the binding station BS, the book block is positioned above the cover C with the spine S of the book block over the center portion CP of the cover. With the book block BB in such position, it will be understood that the book block is substantially in register with the center portion of cover C and that the book block is substantially centered in heightwise relation with the cover.
- the book block is transported from the adhesive application station to the binding station in such a short time that the adhesive substantially does not appreciably cool or otherwise begin to set up before the binding operation begins.
- a combination hydraulic pump/electric motor PM4 is energized so as to pressurize a fluid cylinder 37 to effect the raising of the clamp assembly 35 from its lowered position to a raised binding position in which the clamp assembly 35 is substantially horizontal.
- a surface 38 of the clamp between the clamp members 35a, 35b is moved into engagement with the center portion CP of the cover from below the outer face of the center portion of the cover C so as to raise the cover and to force it into adhesive engagement with the adhesive applied to the spine S of the book block.
- the clamp members 35a, 35b are then power driven toward each other by means of a motor M6 which acts through a self-centering mechanism so as to insure that the clamp members 35a, 35b substantially simultaneously engage the outer surface of the cover of the book immediately above the level of spine S.
- a motor M6 acts through a self-centering mechanism so as to insure that the clamp members 35a, 35b substantially simultaneously engage the outer surface of the cover of the book immediately above the level of spine S.
- the motor M6 stalls, thus insuring that sufficient clamping force has been applied to properly bind the book.
- the cover stretches around the spine and the lower margins of the book block BB proximate the spine S to insure that the cover tightly conforms to the spine of the book block, preferably without the formation of wrinkles in the center portion CP of the cover C. While it has not been found necessary to do so in all cases, for some cover stock materials which are thicker than conventional cover stock material, the cover C may be scored along either side of the center portion CP of the cover in the manner described in U.S. Patent No. 6,142,721 which is herein incorporated by reference.
- the clamp members 35a, 35b hold a clamping force on the front and back face of the cover of the book being bound just above the level of the spine S for only a few seconds to allow the adhesive to properly set (i.e., cool), thereby binding the book block to the inner face of the center portion of the cover.
- the outer surfaces of the clamp members 35a, 35b may be coated with a suitable low friction/non-stick material such as a Teflon tape to insure that cover C does not adhere to the clamp members and to insure that any excess hot melt adhesive may be readily cleaned from the clamp members.
- the spine S of the book block is not necessarily in a tight compressive relation with the cover, after the binding clamp 35 has been moved fully to its raised position, but that there may be a desired gap (e.g., a few mm) between the bottom face of spine S and the inner face of the center portion CP of the cover so as to insure that a layer of adhesive remains between the spine and the cover so as to result in the satisfactory binding of the book block to the cover. It should also be understood that if the spine were tightly forced onto the inner face of the cover, excessive amounts of the still liquid (or otherwise flowable) adhesive may be forced from between the spine and the cover so as to result In a weakened binding of the book.
- transverse grooves (not shown, but which may, for example, be about 0.32 cm (1/8 inch) wide, 0.05 cm (0.020 inches deep), and on about 0.95 cm (3/8 inch) centers) which are optionally formed in the spine S of the book block by the milling knife 31 act as a reservoir for holding an extra amount of the adhesive and to present additional surface area for the adhesive bonding of the pages to the cover and to one another.
- the hot melt adhesive may be omitted and replaced with a room temperature adhesive, such as that described in U. S. Patent No. 6,142,721 , which is herein incorporated by reference.
- a room temperature adhesive such as that described in U. S. Patent No. 6,142,721 , which is herein incorporated by reference.
- a suitable quantity of the room temperature, solid adhesive may be adhered to the inner face of the center portion of the cover C or to the spine S of the book block as the book block is conveyed along the workpath WP.
- the adhesive station AS heretofore described, is replaced with the adhesive application station, as described in the above noted U. S. Patent No. 6,142,721 .
- the binding station BS is replaced with the ultrasonic adhesive activation system described in the above-noted patent.
- an ultrasonic horn as described in the above-noted patent, is brought into working engagement with the lower surface of the center portion CP of the cover C and the tool is caused to resonant to thereby transmit ultrasonic energy from the tool through the thickness of the cover so as to activate or melt the adhesive.
- the ultrasonic energy aids in forcefully driving the now activated or liquefied adhesive into adhesive engagement with pages comprising the book block BB.
- the ultrasonic energy forces the adhesive vertically a short distance (e.g., a few hundredths of an inch) between the lowermost edges of the pages of the book block adjacent the spine S to imbed the edges of the pages of the book block into the adhesive and to insure that the inner face of the center portion of the cover is adhered to the spine of the book block.
- the time required for such ultrasonic energy to activate the adhesive may be very short (a fraction of a second), depending on the thickness and height of the book being bound.
- the adhesive Upon removal of the ultrasonic energy, the adhesive will substantially instantaneously cool, thus allowing the bound book to be quickly released from the clamping members 35a, 35b.
- the printing and binding apparatus 1 may be readily converted between use of hot melt adhesives and room temperature adhesives which must be ultrasonically activated.
- the adhesive application station AS using hot melt adhesive (as herein described) may be removed from the frame 3 as a unit and replaced with the room temperature adhesive applicator and ultrasonic adhesive activation unit, as described in the above-noted patent.
- the adhesive application station may apply the adhesive directly to spine S of the book block BB.
- the adhesive may be applied first to a central or selected area of cover C.
- the term "application of adhesive so as to be disposed between the spine and the cover upon binding of the book", or similar words, is intended to mean either applying the adhesive directly to spine S or directly to a designated area of the cover C.
- cover C and the pages P constituting the book block BB are oftentimes printed on oversize stock which needs to be trimmed along three (3) edges or trim margins TM 1, TM2 and/or TM3 (i.e., along the top, outer, and bottom margins) of the bound book so as to produce a bound book of a precise, predetermined size with uniform top, bottom, and outer edges.
- the cover stock from which the cover C of the on-demand printed book is produced may be of a size such as to allow a wide range of book thicknesses to be printed using the same stock size for the cover.
- the width of the cover center portion CP is adjustable to accommodate books of a wide range of thicknesses and each graphic of each cover can be printed substantially centered with respect to the stock cover size, such that no mechanical adjustments are necessary to print books of varying thicknesses.
- the carriage 7 further transports the now bound book from the binding stations BS to another work station, referred to as the trim station TS, along the workpath WP.
- the trim station TS another work station
- one, two, or three edges of the bound book i.e., the book block BB and the cover C
- the trimming station TS is trimmed (i.e., the above-described trim margins TM are removed) at the trimming station TS to provide the bound book with a precise, predetermined size having neat and uniform edges.
- the cover is bonded to the spine of the book block, but the cover is splayed into a partially open position (i.e., the cover does not lie flat on the book block) and the carriage clamping members 11 a, 11 b are maintained in clamping engagement with the front and back faces of the book block.
- the spine of the book is disposed at the lower horizontal edge of the book and the trailing edge of the book block remains in engagement with the vertical wall 21 of the carriage 7 thereby accurately maintaining the position of the book relative to the carriage.
- control system CONT 1 "knows" the desired final (predetermined) size of the finished book, the size of the stock used for the pages P of the book block BB, and the size of the stock used to print the cover C, the control system has sufficient information to calculate the trim margins TM along the top, bottom, and outer edges of the book so as to result in a finished, trimmed book of a desired size.
- the book clamp motor M2 is energized so as to open the carriage clamp members 11a, 11b and thereby release the bound book B, allowing the book to drop vertically downwardly into a trimming nest, as generally indicated at 41.
- the carriage 7 is advanced along the workpath WP so that the vertical reference surface 21 of the carriage again engages the trailing edge of the book block and nudges the book in the nest 41 in a forward direction (i.e., toward the right-hand end of the apparatus 1, as shown in Fig.

- the elevator is moved along a vertical track 45 on track rollers 47 by a power screw drive 49 which includes a vertical drive screw 51 journalled in bearings 53 mounted to the frame 3 of the printing and binding apparatus.
- the drive screw is rotary driven by an electric stepper motor M7 through a timing belt and pulley drive, as indicated at 55.
- the nest 41 is moved to its raised position (not shown) at which location it receives the bound (but not yet trimmed) book B from the carriage 7.
- the stepper motor M7 is energized so as to rotate the drive screw 51 which lowers the nest 41 from its raised to its lowered trimming positions (as shown in Fig. 2 ).
- the nest 41 includes a book clamp 57, as best shown in Figs. 5 , 7 , and 8 , for holding the bound book B while one or more edges thereof are trimmed.
- the details of the book clamp 57 and the nest 41 will be more fully described hereinafter.
- the book clamp 57 includes an indexing mechanism, as generally indicated at 99 (which is also described hereinafter), that operates to rotate the book B held in the nest 41 through various angles (or through any desired angle) from a first position in which a first edge or trim margin TM1 of the book B is trimmed, to a second in which the book is rotated to a set position, for example rotated 90° such that a second edge or trim margin TM2 of the book is in position such that it may be trimmed, and then to a third position in which the book is rotated to another set position, for example rotated an additional 90° such that a third edge or trim margin TM3 of the book may be trimmed. Finally, book clamp 57 may be retracted or opened to release the trimmed book B.
- an indexing mechanism as generally indicated at 99 (which is also described hereinafter)
- a book shear or trimmer which may be adjustably moved into operating relation with a book held in the nest 41 for trimming one, two, or three sides or edges of the book.
- the trimmer 59 is a knife shear of sufficient length to trim the lengthwise dimension of the largest book B to be bound and trimmed by the apparatus 1 of the present invention.
- the trimmer 59 is vertically mounted on a trim carriage 61 which is mounted for horizontal movement toward and away from an edge of the book B held in the nest 41 such that the horizontal position of the trimmer (and more particularly the vertical plane of the blade of the trimmer) relative to the edge of the book being trimmed determines the amount of the margin of the book B to be trimmed.
- the horizontal position of the trim carriage 61 (and hence the position of the trimmer 59) is under the control of the control system CONT 1, as will be explained.
- the trimmer 59 comprises a trimmer frame 62 in which a guillotine-type shear blade 63 having a shear edge 64 (as shown in Fig. 7 ) is mounted to move between a fully open position and a closed trimming position.
- the trimmer further comprises an anvil 65 against which the book B in the area to be trimmed rests and against which the blade edge 64 cuts through the upper face of the cover C, the pages P of the book block BB, and through the other face of the cover to trim an edge or margin of the bound book B.
- the trimmer further has a book clamp 67 which is operable independently of the trimming blade 63 for firmly holding the book relative to the trimming blade adjacent the trim line (i.e., the line along which the blade 63 will trim the edge of the book upon closing of the trim blade 63) to insure that the trim blade uniformly trims the edge of the book being trimmed.
- a book clamp 67 which is operable independently of the trimming blade 63 for firmly holding the book relative to the trimming blade adjacent the trim line (i.e., the line along which the blade 63 will trim the edge of the book upon closing of the trim blade 63) to insure that the trim blade uniformly trims the edge of the book being trimmed.
- Movement of the trim blade 63 between its open and closed positions is power operated by means of a fluid cylinder, as indicated at 69 (see Figure5 ). Further, the clamp 67 is power driven by another fluid cylinder 71.
- Each of these fluid cylinders is preferably hydraulic, but those skilled in the art will recognize that pneumatic cylinders or other devices may be used.
- Each of the fluid cylinders 69, 71 is supplied hydraulic fluid under pressure from a dedicated unitary hydraulic pump/electric motor (not shown). Such pumps may be driven in forward or reverse directions to reverse the pressure supplied to the cylinders 69, 71 so as to reverse their direction of movement.
- opening and closing of the shear blade and the shear clamp may be controlled (initiated) merely by reversing the operation of the pumps without the need for any expensive hydraulic valves or the like.
- many other arrangements for supplying hydraulic fluid under pressure to the fluid cylinders 69 and 71 may be used and that pneumatic, electromechanical, and/or other means could be used in place of the fluid cylinders themselves.
- the trimmer 59 is mounted on the trim carriage 61 for movement in the horizontal direction toward and away from an edge of the book B being trimmed as the book is held in the nest 41. More specifically, the trim carriage 61 is mounted on track rollers 73 which roll on a trim carriage track 75 that is rigidly mounted to the frame 3 for movement of the trimmer between a retracted position (as shown in Fig. 6 ) where the trimmer will be clear of the maximum size book that can be trimmed. In the retracted position, the book can be rotated in the apparatus into a trimming position as it is held in the nest 41 for presenting another edge or margin of the book to the trimmer for being trimmed.

- the power drive 77 is shown to comprise an electric stepper motor M8 which drives a drive screw 79 by means of a belt and pulley arrangement 81.
- the drive screw 79 is journalled with respect to the trim track 75 by means of bearings 83.
- the stepper motor M8 is controlled so as to accurately position (e.g., to within ⁇ 0.0127 cm (0.005 inches)) the cutting plane of the shear knife 63 relative to the margin of the book B to be trimmed such that a predetermined trim margin TM is removed from the book B along the vertical edge of the book presented to the trim blade.
- trimmer 59 described above is the trimmer described in my U. S. Patent 6,193,458 , which is herein incorporated by reference.

- platen 87 is forcefully moved inwardly toward the book B held in the nest 41 to thereby firmly grip the book between the platen 87 and the vertical wall 93 which in turn is rotatably mounted on the shaft 95 which is carried by the bearings 97.
- the book B is firmly held in place within the nest 41, thereby enabling positioning of the blade 63 relative to the known position of the book in the book nest to enable a predetermined trim margin TM1-TM3 to be trimmed from each of three respective margins or sides of the book B.
- the book B is positioned in the nest 41 such that the geometric center of the finished book is coaxial with the centerline of the book clamp cylinder 85 and the shaft 95 such that, as the book is rotated, the book will rotate about the axis of the finished book (i.e., the center of the book as trimmed).
- the index drive 99 is mounted on the elevator 43 for indexing the shaft in increments of 90° so as to rotate the book B held within the nest 41 through a predetermined angle (e.g., 90°) about the horizontal axis of the shaft 95 to present a second and then a third edge of the book B for being trimmed by the blade 63.
- the index drive is a stepper motor M9 connected to the shaft 95 by means of a belt 103 and pulley arrangement.

- multiple trimming blades could be used to trim the book margins simultaneously.
- a range of sizes of books B held by the nest 41 is depicted that can be accommodated by the trimming station TS of the present invention.
- both the smallest and largest sizes of the books B accommodated by the apparatus of this invention is shown with the spine S of such books B bearing on the upper face of the nest surface 91, thereby properly positioning the book in heightwise orientation relative to the shear blade 63.
- the phantom line circle depicts the swing of the largest size book as the book is rotated from the first position to the second and then the third positions.
- the control system CONT 1 operates to energize stepper motor M8 an amount so as to move shear trimmer 59 horizontally from its retracted position (as shown in Fig. 6 ) to a predetermined trimming position in which the vertical cutting plane of the trimmer is oriented such that the trimmer will shear the trim margin TM1 from the book.
- the pump PM2 is energized so as to close the shear clamp 67 on the book to firmly hold the book while the trim margin TM1 is sheared from the book.
- the shear pump PM1 is energized so as to actuate the cylinder 69 to forcefully move the blade 63 from its open position to its closed position so as to cut the desired trim margin TM1 from the book.
- the pump motors PM1, PM 2 are energized in a reverse direction so as to open the clamp and move the shear blade to its open position.
- the stepper motor M8 is energized so as to horizontally move the trim carriage 61 back to its retracted position from its cutting position.
- the stepper motor M9 is energized so as to index the nest 41 (and hence the book held therein) 90° about the horizontal axis of the shaft 95 to dispose a second edge or trim margin TM2 of the book in a vertical position.
- the control system CONT 1 is provided with information so as to calculate the shear plane of the shear 59 in relation to the book, as discussed above, so that the second trim margin TM2 may be trimmed from the book.
- the stepper motor M8 is energized to move the trim carriage 61 in the horizontal direction toward the book so that the shear plane of the blade 63 is positioned where the shear 59 can remove the second trim margin TM2 from the book.
- pump PM2 is energized to actuate the shear clamp 67 and then the shear pump PM1 is energized so as to trim the second trim margin TM2 from the book.
- the pump motors PM1, PM 2 are energized so as to open the clamp and move the shear blade into its open position and the stepper motor M8 is energized so as to horizontally move the trim carriage 61 clear of the book.
- the book is indexed through another 90° angle so as to position a third edge or trim margin TM3 of the book in a vertical position disposed toward the trim blade 63.
- the shear carriage is moved inwardly toward the book and the vertical plane of the shear blade is positioned so as to trim the third trim margin TM3 from the book, thereby forming a book having three trimmed edges and an accurate, predetermined size.

- a shaft 226 is mounted to the support bracket 212 for rotation about the shaft's axis.
- the tray 210 is mounted on the shaft for rotation with the shaft.
- the left most end 228 of the shaft 226 of the second, book page printer assembly is oriented slightly above the opposite right end 230 of the shaft such that the shaft and tray 210 are angled slightly from the horizontal.
- the support bracket 212 of the second, transfer mechanism 204 is constructed with a C-shaped portion 232 of the bracket that supports the opposite ends of the tray shaft 226.
- the C-shaped portion 232 is mounted to the frame 3 of the printing and binding apparatus 1 for pivoting movement about a vertical axis defined by a main support member 234 of the support bracket. This pivoting connection allows the C-shaped portion 232 of the bracket 212, along with the tray 210 mounted thereto, to swing between an operational position, as shown in Fig. 21-23 , and a maintenance position, as shown in Fig. 24 .

- the transfer mechanism 204 of the second, book page printer assembly rotates the tray 210 to its book block depositing position and releases the book block into the carriage 7 when the carriage is at the opposite end of the workpath WP, adjacent the trimming station TS. Just prior to this point, the carriage 7 will have deposited a bound book into the nest 41 of the trimming station TS and the carriage is therefore empty. Under the control of controller CONT 1, the carriage is moved beyond trimming station TS to a position below transfer mechanism 204 to receive the book block printed by the second printer 200.
- printer 110 may be printing another book block.
- a horizontal positioning plate 240 is mounted to the printer binding apparatus 1 in a position aligned with the tray of the second transfer mechanism 204 and just beneath the carriage 7 when the carriage is positioned beneath the transfer mechanism 204 of the second, book page printer assembly 200 as shown in Figs. 22-24 .
- the spine of the book block is supported on the positioning plate 240 and then the clamping members 11a, 11b of the carriage 7 are moved together to firmly hold the book block.
- the positioning plate can also be provided with vertically extending sides positioned outside and below the clamping members 11 a, 11 b of the carriage 7 to prevent pages of the book block from slipping off of the positioning plate.
- the positioning plate 240 is at an elevation above that of the horizontal plate 13 of the jogging station JS such that a book block deposited into the carriage 7 by the second, book page printer assembly 200 is positioned higher in the carriage than a book block deposited into the carriage by the first, book page printer assembly.
- the positioning plate 240 serves to establish the vertical orientation of the book block as the book block is moved by the carriage 7 back along the workpath WP to the jogging station JS at the opposite end of the workpath. Positioning the book block higher in the carriage 7 prevents the book block from contacting any components of the various work stations as it is brought to the jogging station JS.
- the production rate of perfect bound books can be increased by alternating the feeding of the carriage with a book block printed by either of the first and second, book page printer assemblies.
- the increased production rate should be apparent in situations where the printing of a book block requires more time than it takes the carriage 7 to move along the work path from the jogging station JS to the opposite end of the work path and then return to the jogging station during the production of a perfect bound book. This is often the case when the books being bound have large numbers of pages.
- Incorporating the second, book page printer assembly 200 in the additional embodiment of the printing and binding apparatus also allows the printing and binding apparatus to continue production of perfect bound books when either of the printers of the first and second, book page printer assemblies is being serviced.
- the second, book page printer assembly 200 is positioned adjacent the trimming station TS which periodically requires maintenance. To perform such maintenance, it is helpful to have access to the trimming station TS from above. This is why the C-shaped portion 232 of the support bracket 212 is pivotable about the main support member 234 of the support bracket between the operational position and the maintenance position. As best shown in Fig. 21 , the main support member 234 of the support bracket 212 is positioned adjacent the rear and right side of the C-shaped bracket 232. By releasing the locking mechanism 236, the C-shaped portion 232 of the support bracket 212 and the tray 210 can be pivoted about the main support member 234 into the maintenance position as shown in Fig. 24 .
- the top of the trimming station TS can be easily accessed for maintenance. Finally, when such maintenance is complete, the C-shaped portion 232 of the support bracket 212 and the tray 210 can be quickly pivoted back into the operational position and the printing and binding apparatus returned to production.
- the binding and trimming apparatus 1 is controlled by a programmable controller CONT 1.
- CONT 1 is preferably a programmable controller, such as an AT6400 controller, as described in the aforementioned U. S. Patent 6,193,458 and as illustrated in Fig. 12 thereof.
- the controller CONT 1 for the printing, binding and trimming apparatus controls operation of the black and white printer 110 via a controller CONT 2 and of operation of black and white printer 200 via a controller CONT 3.
- Operation of color printer 114 is controlled by a fourth controller CONT 4.

Description
- This invention relates to an apparatus and method of printing on demand, binding and trimming a perfect bound soft cover book.
- Typically, such soft cover perfect bound books comprise a stacked plurality of text pages (referred to as a book block) having one edge which is referred to as the spine. The cover is of a suitable cover stock that is generally thicker (heavier) than the text pages comprising the book block. The cover has a front portion that overlies the front of the book block, a back portion that overlies the back of the book block, and a center portion spanning across the spine of the book block. A suitable adhesive is applied between the spine of the book block and the inside face of the center portion of the cover. The spine of the book block (i.e., the edges of the text pages along one edge of the book block) is imbedded in the adhesive which, upon curing, securely adheres the pages of the book block to one another and to the center portion of the cover, thereby permitting the book to be opened to any page without the pages coming loose.
- In high volume production processes for manufacturing such perfect bound books, the pages of each book block are usually jogged by specially developed machines prior to the application of adhesive so as to insure that the edges of the pages are properly aligned with one another. The adhesive, typically a suitable hot melt adhesive, is then applied to the spine of the book block. The cover, which is usually preprinted, is then folded around the front, spine, and back of the book block and is firmly clamped to the book block proximate the spine during assembly. In this manner, the adhesive is firmly pressed between the spine of the book block and the inner face of the center portion of the cover to property adhere the cover to the book block while simultaneously adhering the pages to one another.
- Typically, such perfect bound books are printed on pages that are somewhat larger than the desired size (i.e., the length and width) of the finished and bound book to be produced. These books, after they are bound, are typically trimmed along three sides to the desired final dimension in a separate trimming machine. Heretofore, such operations were carried out in separate machines that required considerable adjustment to bind books of different sizes and thus were best suited for production runs of many books. In addition, both prior art binding machines and trimming machines were very expensive.
- In recent years, book printing has undergone changes as computer technology and laser printers have advanced. This new technology now allows for machines capable printing perfect bound books "on-demand". Such on-demand printed books come in a variety of formats and thicknesses (i.e., the number of pages in the book). Thus, there is a need for an economical printing and binding apparatus and system which is sufficiently flexible to allow on-demand printed books of varying size and thickness (at least within a limited range) to be bound and trimmed, even if books of different formats (size) and thickness must be bound one at a time (i.e., with production binding runs consisting of a single book copy). There is a further need for such a printing and binding apparatus and system where such printing and binding operations are fully automated such that a store clerk or attendant need merely to select a prepared data file stored on a computer and send the file to the automated printing and binding apparatus. Thus, the printing and binding apparatus would then generate the printed pages of the book block and the cover of the book, adhere the cover to the book block, and then trim the same. There is yet a further need for such an apparatus and system that is capable of producing various sizes and formats of perfect bound books without the need for undue experimentation or adjustment of the apparatus to produce such different size books.
- In
EP-A-0 895 872 , there is described an apparatus for the demand printing and binding a perfect bound book, according to the preamble ofclaim 1. A method according to the preamble of claim 6 is also known fromEP-A-0 895 872 . - It is against this background, and the limitations and problems associated therewith, that the present invention has been developed.
- Therefore, it is primary objective of the present invention to provide a printing and binding apparatus which automatically adjusts to print, bind, and trim books of different thicknesses and sizes, which increases the rate of production of perfect bound books, and which is reliable in operation.

- The provision of such a printing and binding apparatus which includes a trimmer adapted to receive a bound book from the clamping section so as to trim a first edge thereof, to turn the book 90° to trim a second edge thereof, and to turn the book another 90° to trim a third edge thereof;
- The provision of such a printing and binding apparatus which automatically adjusts to print, bind, and trim books of different thicknesses and sizes such that a single copy of such different sized books may be reliably printed, bound, and trimmed to specified dimensions without manual set up and without binding attempts of sample book blocks and covers;
- The provision of such a printing and binding apparatus having a binding and trimming rate so as to be economical in a variety of commercial settings;
- The provision of such a printing and binding apparatus and method which accommodates books within a wide range of sizes (for example the width and length of the book ranging between about 12.7x17.8 cm (5 x 7 inches) and about 21.6x27.9 cm (8 ½ x 11 inches)) and within a wide range of thicknesses (for example ranging from between 0.63 cm (¼ inch) and approximately 3.81 cm (1 ½ inches), or ranging between about 25 pages and 1000 pages);
- The provision of such a printing and binding apparatus which, upon receiving data corresponding to the size (i.e., the length and width of the book) and thickness (i.e., the number of pages) of the book to be bound, automatically controls the book page printer to print the pages of the book to be arranged in the book block, automatically controls the cover printer to print the cover of the particular book to be bound, automatically adjusts the clamping section to accommodate such book with the cover properly aligned with respect to the spine of the book block, and properly adjusts the trimmer so as to trim the excess width and height of the bound book to produce a bound book corresponding to the desired size for the finished book;
- The provision of such a printing and binding apparatus in which various sizes and formats of books may be accommodated and where various adjustments within the apparatus for the different operations (e.g., positioning of the spine of the book block with respect to the center of the cover and trimming of the edges or margins of the bound book) are automatically adjusted upon inputting such information into the control system, either manually or with such information being associated with data automatically provided to the system;
- The provision of such a printing and binding apparatus which may optionally incorporate a second, book (text) page printer to increase the rate of production of perfect bound books; and
the provision of such a printing and binding apparatus which does not require special training for use, which is of economical construction, which has a relatively fast production speed, and which is reliable in operation. - Other objects will be in part apparent and in part pointed out hereinafter.
- Briefly stated, the printing and binding apparatus of a first embodiment of this invention comprises a book page printer that prints the text pages of the book to be bound and collates the pages to form a book block, and a cover printer that prints the cover of the particular book to be bound. In addition, the first embodiment of the invention comprises a carriage receiving the book block and movable along a workpath.
- The carriage of the printing and binding apparatus of the first embodiment is configured to hold the book block with the pages of the book block oriented such that the width dimension of the pages of the book block extends vertically and such that a lengthwise edge of the book block is the lowermost horizontal edge of the book block (this lowermost edge being referred to as the spine of the book block). The workpath preferably has a jogging station, a milling station, an adhesive application station, a clamping station, and optionally a trimming station located therealong. The carriage receives the initially collated pages of the book block from the book page (text page) printer transfer mechanism and loosely holds the loose pages of the book block such that a jogging mechanism may mechanically vibrate the pages so as allow the pages to move relative to one another in a manner such that the edges of the pages constituting the spine of the book block are substantially in the same horizontal plane and such that widthwise edges of the pages are substantially in the same vertical planes.
- In operation, the carriage securely grips the jogged pages and transports the book block from the jogging station to the milling station where a suitable tool roughs the lowermost margin of the book block so as to insure that the spine is substantially coplanar and has a good adhering surface. The carriage then transports the book block to the adhesive application station where a suitable adhesive is applied to the spine of the book block. The cover printer prints a book cover in black and white or color and transfers the book cover to the workpath where it is precisely positioned in the binding station of the apparatus relative to the book block being conveyed along the workpath of the apparatus. To increase time efficiency, this is preferably done while the book block is being jogged and collated by the printing and binding apparatus and while the book block receives the application of adhesive along the spine of the book block. At the binding station, the cover of the bound book is positioned such that the center portion of the cover is in register with and is substantially aligned with respect to the spine of the book block with the adhesive disposed between the spine of the book block and the inner face of the cover. The binding station includes a clamp which engages the cover proximate the spine and forcefully compresses the front and back portions of the cover onto the front and back faces of the book block to thereby adhere the center portion of the cover to the spine of the book block, while simultaneously bonding the pages of the book block to one another with the adhesive bonding. The carriage further moves the bound book along the workpath to the trimming station that has a trimming blade capable of trimming the non-spine edges of the bound book. The trimming station has a book positioner which positions a first edge of the book to be trimmed in a desired position with respect to the trimming blade such that when the trimming blade is actuated, a predetermined amount of the cover and the book block along this first edge is trimmed from the bound book. The trimming station further has a book turning mechanism that turns the bound book 90° such that a second edge of the book to be trimmed faces the trimming blade. The book positioner moves the bound book relative to the trimming blade so that upon actuation of the trimming blade, a predetermined amount of the cover and the book block along this second edge is trimmed from the book. The book turning mechanism then turns the bound book another 90° such that a third edge of the bound book to be trimmed faces the trimming blade. Once again, the book positioner moves the bound book relative to the trimming blade so that upon actuation of the trimming blade, a predetermined amount of the cover and the book block along this third edge is trimmed from the book. The trimming process produces a perfect bound book trimmed along three edges to a predetermined size.
- While the principal advantages and features of the present invention have been described above, a more complete and thorough understanding and appreciation for the invention may be obtained by referring to the drawings and the detailed description of embodiments of the invention, which follow.

- Referring now to the drawings, and in particular to
Figs. 1 - 9 , a book binding and trimming apparatus, generally as described in myU. S. Patent 6,193,458 (WO-A-00 66366 U. S. Patent 6,193,458 is herein incorporated by reference. However, to better understand the construction and operation of the on demand book printing, binding and trimming apparatus of this invention, certain key parts of the above-noted book binding and trimming apparatus will be herein described. - As shown in
Fig. 1 , a portion of a first embodiment of a printing and binding apparatus of this invention is indicated byreference character 1. Additional component parts of the first embodiment, a book page printer and its book block transfer mechanism, as well as a color cover printer and its cover transfer mechanism are not shown inFig. 1 in order to provide an unobstructed view of the top of the binding and trimming apparatus. Thebook page printer 110 and itstransfer mechanism 112 and thebook cover printer 114 and its transfer mechanism orconveyor 116 are shown in their relative positions inFig. 14 , which is a view of the apparatus similar toFig. 1 . In the illustrated embodiment of the apparatus, thebook page printer 110 is a QMS4032 black and white book body printer and thebook cover printer 114 is a QMS330EX color laser printer. However, these are only two examples of printers that could be employed with the apparatus and other printers may alternatively be employed. In fact, because the manufacturers of such printers are constantly introducing new models with better performance and capabilities, it will be understood that such newly introduced printers by any manufacturer may be used with or even retrofitted to the on demand book printing, binding and trimming apparatus of the present invention. The printers and their transfer mechanisms as shown in the drawings will be described in greater detail below. - The printing and
binding apparatus 1 has aframe 3 made of welded square steel tubes. Theframe 3 has a pair of spacedhorizontal frame rails apparatus 1. A metal cover or shroud SH may be secured to theframe 3 and is shown inFig. 13 . The shroud has been omitted from the other drawing figures for the sake of clarity. - A
conveyor 5 is provided between theframe rails conveyor 5 includes acarriage 7 movable in a horizontal direction on carriage wheels CW which bear oncarriage rails respective frame rails Fig. 3 . The carriage is power driven along the carriage rails by means of a conveyor stepper motor M1 that drives the carriage via a toothed timing belt and pulley arrangement, as indicated at CB. As best shown inFig. 4 , one end of the timing belt is attached to one end of thecarriage 7 and the belt is trained around a drive pulley on the motor M1 and around other pulleys that are journalled to theframe 3 to the other end of the belt which is attached to the other end of the carriage. Preferably, the conveyor motor M1 is a stepper motor driven by acontrol system CONT 1, as will be hereinafter described and which is shown inFig. 12 , so that the position of the carriage (and hence the book block carried thereby) is accurately known (i.e., to within about 0.005 inches) with respect to a reference surface of thecarriage 7. In this manner, the position of the book block is accurately known by thecontrol system CONT 1 as the book block is carried along the workpath where it is bound and trimmed, as will be hereinafter discussed in detail. In this manner, upon energization and de-energization of the motor M1 under the control of thecontrol system CONT 1, the carriage may be accurately stopped at any position or work station along the workpath WP to accurately position the book block at a desired location. When the carriage is at the end of the workpath, the motor M1 can be driven in reverse so as to move thecarriage 7 in a reverse direction along the conveyor so as to return the carriage to its starting position where it can then receive the next book block to be bound. In a variant embodiment, the carriage can be advanced past the trimmer station to a second printing station where the carriage receives a second book block prior to the carriage being driven in reverse to return it to a starting position from which the second book block can be bound and trimmed. - As shown in
Fig. 10 , each book block BB comprises a plurality of pages P, which generally constitute the text pages of a book to be bound. The number of pages making up the book block may range between a minimum number and a maximum number of pages, depending on the range of binding thicknesses to be accommodated by the binding and trimmingapparatus 1. In the first embodiment of the invention, the thickness of the book block BB ranges from about 0.63 cm (¼ inch) (or less) to about 3.81 cm (1 ½ inches) (or more). This thickness range may accommodate books from about 25 pages up to about 1000 pages (or more), depending on the thickness of the paper used. The minimum thickness of books to be bound by theapparatus 1 is generally dependent on the minimum thickness of the book block capable of being adhesive bound to a cover. Generally, book blocks with less than about 25 pages are not perfect bound, but in theory, a book with even a single page could be bound by other embodiments of the present invention. - Typically, the pages P of the book block BB are duplex printed on both their front and back faces and are rectangular in shape, having a widthwise dimension and a lengthwise dimension. The pages may, for example, range between a 12.7x17.8 cm (5x7 inch) rectangular format and a 21.6x27.9 cm (8½ x 11 inch) rectangular format, or any number of rectangular formats within the above range. Of course, it should be understood that other formats may be accommodated by adjusting the size of the printing and binding apparatus. The printing and
binding apparatus 1 of the first embodiment of the present invention automatically accommodates any book size within the ranges of sizes thicknesses (i.e., number of pages), as is discussed below. One edge of the book block BB is referred to as the spine S of the book block. As contemplated, the spine of the book block corresponds to the lowermost horizontal edge of the book block (which is a lengthwise (major) rectangular dimension of the pages of the book block) when the book block BB is placed in the carriage of the printing andbinding apparatus 1, as shown inFigs. 1 and2 . While the book block BB is shown to have its longest or major dimension (i.e., its length) as the spine of the book to be bound, those skilled in the art will recognize that the shorter (minor) width of the book block may be used as the spine S instead. - As seen in
Figs. 13 ,14 ,15 , and17 , the first book page (text page)printer 110 is integrated into the book printing andbinding apparatus 1 adjacent the jogging station JS. Thebook page printer 110 is supported adjacent the apparatus by asupport platform 118 that is attached to the tubular frame of the apparatus by a vertically hingedsupport 120. The support is hinged such that the printer can be swung away from its operating position when the printing and binding apparatus requires maintenance. As best seen inFigs. 15 and17 , theprinter platform 118 supports thebook page printer 110 at an angled orientation relative to the apparatus. Thepage ejection slot 122 of the printer is positioned adjacent theapparatus 1 where a printed page of a book being printed by thebook page printer 110 will be ejected from theprinter slot 122 over the apparatus jogging station JS. Thearrow 124 indicates the direction in which printed pages are ejected from the bookpage printer slot 122. The operation of thebook page printer 110, including the pages of the book to be printed, is controlled by the apparatus computercontrol system CONT 1 with which thebook page printer 110 communicates. - Positioned adjacent the
book page printer 110 and over the jogging station JS of theapparatus 1 is the book pageprinter transfer mechanism 112. Thepage transfer mechanism 112 is supported over the jogging station JS by asupport panel 128 that projects upwardly from theframe 3 of theapparatus 1 at the left hand end of the apparatus as viewed inFig. 14 and by asupport rod 130 that projects outwardly over the jogging station JS from theprinter hinge support 120. Ashaft 132 is mounted for rotation to thesupport panel 128 and to thesupport rod 130 and projects over the jogging station JS. As best seen inFig. 16 , theshaft 132 is angled slightly such that the end of the shaft closest to the left hand end of theapparatus 1, as viewed inFig. 14 , will be slightly lower than the opposite end of the shaft. Mounted on theshaft 132 for rotation therewith is arectangular collator tray 134. Thetray 134 projects out to a position adjacent thepage ejection slot 122 of thebook page printer 110 where it will receive printed pages ejected from the printer. As best seen inFig. 15 , thetray 134 on theshaft 132 angles downwardly away from thebook page printer 110 and is also angled downwardly toward the left hand end of the apparatus as shown inFig. 14 . Mounted at the back of thetray 134 is a box shaped bin having first 136 and second 138 side walls, arear wall 140, and atop wall 142. The bin receives pages ejected from thepage printer 110 and holds the pages on thetray 134 in the initial formation of the book block. A vibratingmechanism 144 is mounted on thesecond side wall 138 of the bin. Operation of the vibratingmechanism 144, which is controlled by thecontrol system CONT 1, provides an initial jogging and collating of the printed pages of the book block on thetray 134 toward theback wall 140 and thesecond side wall 138 of thetransfer mechanism 112 due to the angled orientation of theshaft 132 and thetray 134 on the shaft. - Mounted on the
back wall 140 of thetray 134 is a small reversible, direct currentclamping mechanism motor 146. Theclamping mechanism motor 146 is selectively controlled by thecontrol system CONT 1 to rotate ascrew shaft 148 of the motor in opposite directions. Thescrew shaft 148 is threaded into aclamping arm 150 at one end of the arm. Thearm 150 is mounted by apivot pin 152 connection to thetop wall 142 of the tray bin. The arm has aclamping pad 154 at an opposite end of the arm from thescrew shaft 148. Rotation of thescrewshaft 148 by theclamping mechanism motor 146 in one direction will cause the arm to pivot about itspivot pin 152, thereby allowing theclamping pad 154 to clamp down on the book block that has been initially collated in the bin of thetransfer mechanism 112. Rotation of thescrewshaft 148 in the opposite direction will cause theclamping pad 154 to pivot away from the book block, thereby releasing the book block. Contact switches (not shown) are mounted on the clamping arm to produce signals that indicate when a book block is clamped securely by the arm and when the arm is moved to a position to release a book block. - A
shaft arm 156 is secured to thetransfer tray shaft 132 and projects outwardly a short distance from the shaft. An alternating currenttransfer mechanism motor 158 is mounted to theframe 3 of theapparatus 1 as shown inFigs. 15 and17 and has amotor arm 160 that is secured to the motor shaft and that projects outwardly from the motor shaft. Theshaft arm 156 and themotor arm 160 are interconnected by a connectingrod 162 that is mounted to the two arms at its opposite ends by pivot connections. Selective operation of thetransfer mechanism motor 158 will cause its shaft, themotor arm 160, and consequently theshaft arm 156 to move through an arc segment which causes thetray 134 to pivot between a printed page receiving position shown inFig. 15 and a book block depositing position shown inFig. 17 . Themotor arm 160 is preferably shorter than theshaft arm 156 such that thetray 134 will move from the page receiving position, to the book block depositing position, and back to the page receiving position simply by rotating themotor arm 160 through a 360° rotation. This allows thetransfer mechanism motor 158 to be a simple, non-reversible motor. - In operation, the
tray 134 of the book pageprinter transfer mechanism 112 is first positioned in its page receiving position shown inFig. 15 by operation of thetransfer mechanism motor 160 that is controlled by thecontrol system CONT 1. Pages printed by thebook page printer 110 are ejected from theprinter slot 122 and are collected on thetray 134. Operation of thebin vibrating mechanism 144 causes the printed pages to be initially jogged and collated as they are collected into the corner of the tray defined by theback wall 140 and thesecond side wall 138 of the bin. When the entire book block has been printed and initially collated on thetray 134, theclamping mechanism motor 146 is operated causing theclamping arm 150 to close down on the book block with theclamping pad 154 of the arm securely holding the printed book block on the tray. Thetransfer mechanism motor 160 is then operated causing the tray to move to its book block depositing position shown inFig. 17 . In this position, theclamping mechanism motor 146 is operated causing theclamping arm 150 to open and release the book block from thetray 134 such that the book block will fall into thecarriage 7 that holds the book block during further steps in the printing and binding process of the book. - As shown in
Fig. 11 , each book block BB is adapted to be bound in a suitable book cover C by a binding technique or method referred to as perfect binding. Typically, books bound by the perfect binding method are soft cover books. The book cover C is typically formed of a suitable stock of heavier weight than the pages of the book block BB and may be coated so as to have a superior finish and may be color printed. The cover has a front face FC, a back face BC, and a center portion CP therebetween. The width of the center portion CP of the cover C generally corresponds to the thickness of the book block to which it is ultimately attached. Typically, the pages P of the book block and the cover C are somewhat oversize relative to the desired size of the finished, bound book such that the margins of the bound book can be trimmed to a predetermined size after the book block has been bound to the cover to result in a perfect bound book having the desired size with even edges along the sides or margins (preferably along three sides) of the book. As shown inFigs. 10 and 11 , the oversize margins of the book block BB and of the cover C are shown as trim margins, TM1-TM3. For example, a book having a format of any finished (trimmed) size ranging from between about 12.7x17.8 cm (5 x 7 inches) to just slightly less than 21.6x27.9 cm (8 ½ x 11 inches) may be printed on conventional 21.6x27.9 cm (8 ½ x 11 inch) sheet stock. Thetext page printers - As noted, the book block BB and cover C may be printed by any method. However, because the printing and
binding apparatus 1 of the present invention is capable of instant setup for any size or format of book to be bound (i.e., the size of the pages and the thickness of the book) within a predetermined range of book sizes (e.g., from 12.7x17.8 cm (5 x 7 inches) to about 21.6x27.9 cm (8 ½ x 11 inches), and any combination of rectangular sizes within such range, and in thickness ranging from about 25 pages to about 1000 pages or more), the printing and binding apparatus of the present invention is particularly well-suited to print, bind, and trim a single copy (or a small run quantity) of perfect bound book(s) printed on-demand as described inU. S. Patent 5,465,213 , the disclosure of said patent being herein incorporated by reference. In this manner, the on-demand printing apparatus of the present invention can automatically, from the data relating to the size and thickness of the book to be bound, determine (calculate) the width of the center portion CP of the cover C and the width of the trim margins TM1-TM3 so as to bind any size book within the range of book sizes that can be accommodated by the printing andbinding apparatus 1 of this invention. The second book may be of an entirely different size and thickness than the first book and the printing andbinding apparatus 1 will automatically accommodate this second book so long as the second book is also within the range of book sizes that can be accommodated by the printing and binding apparatus. The binding process of the printing and binding apparatus has a sufficiently fast operational cycle such that it will finish binding and trimming one book while a second book is being on-demand printed. - As shown in
Figs. 13 and14 , thebook cover printer 114 is positioned adjacent the binding station BS of the printing andbinding apparatus 1. Thebook cover printer 114 is shown pulled slightly away from the apparatus inFig. 13 to illustrate how it can be easily separated from the apparatus for servicing. Thecover printer 114 is shown in its operative position relative to the apparatus inFig. 14 . Thecover printer 114 has aslot 166 on the top of the printer where color printed book covers are ejected from the printer. Mounted on the top of the cover printer is the coverprinter transfer mechanism 116 that projects outwardly from the printer to a position adjacent the binding station BS of the printing andbinding apparatus 1. - The
cover transfer mechanism 116 is comprised of a pair of C-shapedchannels printer 114 to positions adjacent the binding station BS of the apparatus. A plurality of cross bars 172 extend between the twochannels cover transfer mechanism 116. An additional plurality ofbars 174 extend between pairs of thecross bars 172 rigidifying the frame and providing a sliding surface for the cover to be printed by thecover printer 114. Apivot rod 176 extends across an intermediate portion of the frame and has a plurality ofpawls 178 secured to the rod. Thepivot rod 176 is connected to aswitch 180 that controls the operation of thecover transfer mechanism 116 as will be explained. - As shown in
Figs. 14 ,19, and 20 , two pairs ofroller shafts channels pivot rod 176. Each of the shafts of the pairs are positioned above and below each other. Each of the pairs ofshafts rollers sprocket connection 190 shown inFig. 14 . The chain andsprocket connection 190 and the mutual engagement between the roller pairs 186, 188 provide a driving arrangement between the rollers where, when the rollers on the upper shafts rotate in a clockwise direction, the rollers on the lower shafts rotate in a counter clockwise direction and vice versa. A reversible motor (not shown) is controlled by the control system CONT 1 and is operatively connected to the chain andsprocket connection 190 to drive the rotation of the upper and lower rollers in opposite directions of rotation. The motor (not shown) is also operatively connected with thepivot rod switch 180 to control the motor's direction of rotation, and thus the direction of rotation of therollers - When the
book cover printer 114 and itstransfer mechanism 116 are operated, as each book cover is printed by the printer, the book cover is ejected from the top of the printer in the direction indicated by thearrow 192 shown inFig. 19 . The cover C being ejected from the printer contacts the plurality ofpawls 178 and causes the pawls to move from their first position shown in solid lines inFig. 19 to their second position shown in dashed lines inFig. 19 . The movement of the pawls to their second position activates thepivot rod switch 180, which in turn, controls the motor of thecover transfer mechanism 116 to rotate theupper rollers 186 of each pair of rollers to rotate in the clockwise direction and thelower rollers 188 of each pair of rollers to rotate in the counter clockwise direction as viewed inFig. 19 . The cover being ejected from thecover printer 114 is received between the pairs of rollers shown to the left inFig. 19 and the rotation of the rollers transports the cover to the left as viewed inFig. 19 between the opposed pair ofchannels bars 174 of the transfer mechanism frame. This movement of the cover continues until it is completely ejected from thecover printer 114 and moves past the plurality ofpawls 178, causing thepawls 178 to move from their second position back to their first position shown in solid lines inFig. 19 . This movement of the pawls causes thepivot rod switch 180 to control the transfer mechanism motor (not shown) to reverse its rotation. The reverse rotation of the motor causes theupper rollers 186 of the pairs of rollers to now rotate in the counter clockwise direction and their matinglower rollers 188 to rotate in the clockwise direction. This, in turn, causes the pairs ofrollers Fig. 19 between the pairs of rollers and over thepawls 178 to the binding station BS of the apparatus. Therollers transfer mechanism 116 transfer the cover over theclamp members stop switch 196 indicating the proper position of the cover over the center of thebinding clamp 38. Alternatively, when only one size of cover stock is used to print the covers of all sizes of books, the positioning pins and the stop switch can be eliminated and replaced by a simple bin that is centrally positioned with respect to the binding clamps. In either manner, thecover printer 114 and its associatedtransfer mechanism 116 automatically operate to provide a color printed cover to the printing andbinding apparatus 1 where it is ready to be secured to the book block by the apparatus. - Regardless of how the book block BB and cover C are printed, the book block BB is loaded in the
carriage 7 which is movable along theconveyor 5 in a horizontal direction along the workpath WP. As will be described in detail hereinafter, thecarriage 7 is substantially centered on the workpath WP and has acarriage clamping mechanism 9, which is selectively actuated to firmly hold the pages P of the book block relative to one another. Thisclamping mechanism 9 comprisesvertical clamping members carriage 7. The self-centering drive of the clampingmembers members - As shown in
Figs. 1 ,2 , and4 , thecarriage 7 and the book block BB carried thereby are shown in a first station, referred to as a jogging station JS, at which location the book block is deposited in thecarriage 7, but is not clamped. In the jogging station JS, the pages of the book block are mechanically vibrated or jogged so as to allow the pages to move relative to one another such that the bottom most edges of all of the pages of the book block bear on ahorizontal surface 13 and the leading, trailing, and upper edges of the pages are substantially aligned with one another. As previously stated, the lower lengthwise dimension of the book block, referred to as the spine S of the book block, rests on thesurface 13 of the jogging station JS. The jogging operation is carried out by vibrating the book block in the carriage by an electro-mechanical vibrating mechanism 15 (as shown inFig. 2 ), which has a vibrating magnetic coil (solenoid) 17 connected to thesurface 13 byresilient arms 19. The magnetic vibrating coil is energized by a suitable power supply (not shown) under the control of thecontrol system CONT 1. Preferably, during the jogging operation, thecarriage clamp 9 is positioned in such manner as to loosely hold the pages P of the book block in vertical positions relative to one another such that they may move relative to one another during the jogging operation to permit the pages to align with one another. During the jogging operation, the pages of the book block are preferably vibrated in such manner that the pages move rearwardly relative to thecarriage 7 such that the trailing edges of the pages of the book block contact avertical surface 21 of the carriage. Thevertical surface 21 of thecarriage 7 thus provides an accurate reference position for the trailing edge of the book block that is later used to positively position the book block relative to the components of the apparatus as the book block is bound and trimmed. - One arrangement for accomplishing this jogging of the book block is shown schematically in
Fig. 18. Fig. 18 shows thecarriage 7 mounted on a vibrating device comprised of an upperangled block 300 and a lowerangled block 302 with the vibratingmechanism 304 mounted between the two blocks. With theangled blocks mechanism 304, operation of the mechanism is split into two, perpendicular force components with one component directed upwardly and the other directed horizontally to the left as shown inFig. 18 . Thus, operation of the vibratingmechanism 304 will jog and collate the pages of the book block on thebottom surface 13 of the jogging station JS and against the leftvertical surface 21 of the station. - Upon completion of the jogging operation (which may only take a second or so), the carriage clamp motor M2 is energized so at to actuate the
clamp 9 to firmly clamp the pages of the book block together and to firmly hold the book block BB in a fixed position relative to thecarriage 7 as the carriage is moved along the workpath WP. The thickness of the book block BB being bound and the clamping pressure exerted by theclamp members - The
control system CONT 1, upon being supplied with the size of the book block and cover of the book being bound, can then calculate the position of the leading edge of the book block relative to the carriage by reference to thevertical carriage surface 21. Thus, both the trailing and leading edges of the book block can be accurately located relative to each station of the printing and binding apparatus as well as the trimmer as the carriage is moved along the workpath from one station to the next. - Additionally, the
horizontal plate 13 of the jogging station serves as a reference surface for establishing the elevation of the spine S of the book block as the latter is transported along the workpath WP. As noted above, thecarriage 7 is moved along the workpath WP by the stepping motor M1 via the timing belt and pulley arrangement CB such that the position of the carriage (and hence the position of the book block carried thereby) may be accurately controlled at any point along the workpath to an accuracy of within about 0.0127 cm (0.005 inches) or about 0.127 mm. - The
carriage 7 and the book block BB carried thereby are moved by theconveyor 5 from the jogging station JS to a second station along the workpath WP. This second station is a milling station MS at which a rotary milling orspine grooving head 23 mills or otherwise removes material from the lowermost edge of each of the pages (i.e., the spine S) of the book block to thereby roughen the surface of the spine to better bond the adhesive to the spine and to insure that the spine is coplanar. The milling station MS is provided with a vacuum dust ordebris collector 27, driven by a motor M3. The inlet opening for the dust collector is shown at 29 inFig. 9 . The millinghead 23 is rotary driven by a motor M4 at high speed and has a milling blade 31 (as shown best inFig. 2 ) which engages the spine of the book block as the latter is conveyed over the milling head by thecarriage 7. It should be understood that the milling operation is only intended to remove only a minimal amount of material from the spine S of the book block, to roughen the surface of the spine and create a good adhesive gripping surface on the spine. Themilling blade 31 is a single blade carried on the rapidly rotating milling head, configured to roughen and cut shallow grooves in the spine as the carriage moves the book block thereover. These grooves hold a supply of adhesive and facilitate the spine of the book block being firmly adhered to the center portion CP of the cover. The milling station utilized in the preferred embodiment of the printing and binding apparatus can be commercially acquired from Martin Yale Industries, Inc. of Wabash, Indiana. - Downstream of the milling station MS along the workpath WP is next located an adhesive application station AS. As shown, this adhesive application station includes a hot melt adhesive bath 31 (as shown in
Fig. 1 ) in which a quantity of a suitable hot melt adhesive, of the type which is well known in the book binding art, is heated to a liquid state. One such adhesive that has worked well in conjunction with the system and method of this invention is a hot melt adhesive commercially available from Capital Adhesives of Mooresville, Indiana, recommended by the manufacturer for binding books. However, any suitable hot melt or cold melt adhesive may be used in accordance with this invention. - The adhesive application station AS further has an
adhesive applicator roller 33 which is partially immersed in the liquid hot melt adhesive and which is rotary driven by a motor M5 such that the roller picks up a coating of the liquid hot melt adhesive on its cylindrical face. The upper portion ofroller 33 is positioned to be generally tangent to the spine of the book block BB as the book block is conveyed by thecarriage 7 along the workpath WP over theroller 33. Thus, as the spine of the book block is conveyed over theroller 33, a quantity of hot melt adhesive is applied to the spine of the book block. Theroller 33 is rotary driven by the motor M5 at approximately the same speed as that of thecarriage 7 moving along the workpath WP so as to pick up molten adhesive from the bath 34 and lay down a substantially continuous coating of the liquid hot melt adhesive on the spine S of the book block as the latter is conveyed over the roller. The roller motor M5 is energized and de-energized by a micro-switch (not shown) tripped by movement of thecarriage 7 as it approaches and leaves the adhesive station. The hot melt bath and roller are commercially available. It should be understood that thebath 31 is provided with suitable heaters so as to heat the adhesive to a desired temperature and is further provided with a thermostat control system to maintain the adhesive in the bath at a desired temperature. - While the apparatus described herein is shown to utilize a hot melt adhesive, those skilled in the art will recognize that a cold (room temperature) adhesive could be used as well.
- The book block BB is conveyed by the
carriage 7 from the adhesive application station AS to the next work station, which is the binding station BS. At the binding station thebinding clamp 35 is provided. The binding clamp is preferably of the type that is commercially available. The binding clamp includes a pair of self-centering, power operatedclamp members clamp members Fig. 1 , theclamp members - Referring to
Fig. 2 , it can be seen that theclamp members carriage 7 such that the clamp members are disposed to engage the side faces of the book block below the level of thecarriage clamp members rail 3a and is selectively movable between a lowered position in which theclamp members carriage 7 moves the book block (with the adhesive applied to the spine) into position over thebinding clamp 35 assembly, and a raised position where thebook block spine 5 engages against the bindingclamp 38 and is positioned between theclamp members clamp members clamping members members - When the
carriage 7 with the book block therein is stopped at the binding station BS, the book block is positioned above the cover C with the spine S of the book block over the center portion CP of the cover. With the book block BB in such position, it will be understood that the book block is substantially in register with the center portion of cover C and that the book block is substantially centered in heightwise relation with the cover. The book block is transported from the adhesive application station to the binding station in such a short time that the adhesive substantially does not appreciably cool or otherwise begin to set up before the binding operation begins. With the book block substantially correctly positioned with respect to the cover (i.e., the center of the spine S of the book block is centered with respect to the cover both laterally and longitudinally), a combination hydraulic pump/electric motor PM4 is energized so as to pressurize afluid cylinder 37 to effect the raising of theclamp assembly 35 from its lowered position to a raised binding position in which theclamp assembly 35 is substantially horizontal. As the clamp is raised, asurface 38 of the clamp between theclamp members clamp members clamp members clamp members - As the
clamp members U.S. Patent No. 6,142,721 which is herein incorporated by reference. Theclamp members clamp members binding clamp 35 has been moved fully to its raised position, but that there may be a desired gap (e.g., a few mm) between the bottom face of spine S and the inner face of the center portion CP of the cover so as to insure that a layer of adhesive remains between the spine and the cover so as to result in the satisfactory binding of the book block to the cover. It should also be understood that if the spine were tightly forced onto the inner face of the cover, excessive amounts of the still liquid (or otherwise flowable) adhesive may be forced from between the spine and the cover so as to result In a weakened binding of the book. Furthermore, it should be understood that the transverse grooves (not shown, but which may, for example, be about 0.32 cm (1/8 inch) wide, 0.05 cm (0.020 inches deep), and on about 0.95 cm (3/8 inch) centers) which are optionally formed in the spine S of the book block by the millingknife 31 act as a reservoir for holding an extra amount of the adhesive and to present additional surface area for the adhesive bonding of the pages to the cover and to one another. Yet further, it should be understood that, with the pages of the book block BB held tightly by thecarriage clamp members binding clamp assembly 35 causes the cover to splay outwardly relative to the book block with the front and back cover FC and BC, respectively, being in nearly horizontal position beneath thecarriage 7. - Yet further, it should be understood that the hot melt adhesive, as above described, may be omitted and replaced with a room temperature adhesive, such as that described in
U. S. Patent No. 6,142,721 , which is herein incorporated by reference. In such instance, rather than applying a coating of a hot melt adhesive to the spine S of the book block BB (as above described), a suitable quantity of the room temperature, solid adhesive may be adhered to the inner face of the center portion of the cover C or to the spine S of the book block as the book block is conveyed along the workpath WP. In the event that such room temperature adhesive is used, the adhesive station AS, heretofore described, is replaced with the adhesive application station, as described in the above notedU. S. Patent No. 6,142,721 . Furthermore, the binding station BS, as described above, is replaced with the ultrasonic adhesive activation system described in the above-noted patent. In such ultrasonic adhesive activation systems, an ultrasonic horn (tool), as described in the above-noted patent, is brought into working engagement with the lower surface of the center portion CP of the cover C and the tool is caused to resonant to thereby transmit ultrasonic energy from the tool through the thickness of the cover so as to activate or melt the adhesive. The ultrasonic energy aids in forcefully driving the now activated or liquefied adhesive into adhesive engagement with pages comprising the book block BB. In this manner, the ultrasonic energy forces the adhesive vertically a short distance (e.g., a few hundredths of an inch) between the lowermost edges of the pages of the book block adjacent the spine S to imbed the edges of the pages of the book block into the adhesive and to insure that the inner face of the center portion of the cover is adhered to the spine of the book block. It should be noted that the time required for such ultrasonic energy to activate the adhesive may be very short (a fraction of a second), depending on the thickness and height of the book being bound. Upon removal of the ultrasonic energy, the adhesive will substantially instantaneously cool, thus allowing the bound book to be quickly released from the clampingmembers binding apparatus 1 may be readily converted between use of hot melt adhesives and room temperature adhesives which must be ultrasonically activated. In order to readily accomplish this changeover, the adhesive application station AS using hot melt adhesive (as herein described) may be removed from theframe 3 as a unit and replaced with the room temperature adhesive applicator and ultrasonic adhesive activation unit, as described in the above-noted patent. - Within the broader aspects of this invention, the adhesive application station may apply the adhesive directly to spine S of the book block BB. Alternatively, the adhesive may be applied first to a central or selected area of cover C. The term "application of adhesive so as to be disposed between the spine and the cover upon binding of the book", or similar words, is intended to mean either applying the adhesive directly to spine S or directly to a designated area of the cover C.
- As noted above, the cover C and the pages P constituting the book block BB are oftentimes printed on oversize stock which needs to be trimmed along three (3) edges or trim
margins TM 1, TM2 and/or TM3 (i.e., along the top, outer, and bottom margins) of the bound book so as to produce a bound book of a precise, predetermined size with uniform top, bottom, and outer edges. The cover stock from which the cover C of the on-demand printed book is produced may be of a size such as to allow a wide range of book thicknesses to be printed using the same stock size for the cover. To facilitate the use of a common cover stock size, the width of the cover center portion CP is adjustable to accommodate books of a wide range of thicknesses and each graphic of each cover can be printed substantially centered with respect to the stock cover size, such that no mechanical adjustments are necessary to print books of varying thicknesses. - In accordance with one aspect of the printing and
binding apparatus 1 of the present invention, thecarriage 7 further transports the now bound book from the binding stations BS to another work station, referred to as the trim station TS, along the workpath WP. In the manner as will be described, one, two, or three edges of the bound book (i.e., the book block BB and the cover C) are trimmed (i.e., the above-described trim margins TM are removed) at the trimming station TS to provide the bound book with a precise, predetermined size having neat and uniform edges. Referring toFig. 2 , as the bound book is transported by thecarriage 7 from the binding station BS to the trimming station TS, the cover is bonded to the spine of the book block, but the cover is splayed into a partially open position (i.e., the cover does not lie flat on the book block) and thecarriage clamping members vertical wall 21 of thecarriage 7 thereby accurately maintaining the position of the book relative to the carriage. In this manner and since thecontrol system CONT 1 "knows" the desired final (predetermined) size of the finished book, the size of the stock used for the pages P of the book block BB, and the size of the stock used to print the cover C, the control system has sufficient information to calculate the trim margins TM along the top, bottom, and outer edges of the book so as to result in a finished, trimmed book of a desired size. - As the
carriage 7 moves along the workpath WP to the trimming station TS, the book clamp motor M2 is energized so as to open thecarriage clamp members nest 41, thecarriage 7 is advanced along the workpath WP so that thevertical reference surface 21 of the carriage again engages the trailing edge of the book block and nudges the book in thenest 41 in a forward direction (i.e., toward the right-hand end of theapparatus 1, as shown inFig. 1 ), thereby accurately positioning the book in thenest 41 relative to a trimming knife (as will be hereinafter described) so that the trim margins TM may be accurately trimmed from the book to give the book its predetermined dimensions. With the book properly positioned in thenest 41, the book is positioned with its spine constituting its lower edge, with its pages vertical, and with one edge to be trimmed disposed toward the trimmer. The front and back faces FC, BC of the cover C are disposed against the front and back pages of the book block such that the book is in its normally closed position. - The
nest 41 of the trimming station TS is mounted on a verticallymovable nest elevator 43 that may be selectively moved in the vertical direction. The elevator is moved along avertical track 45 ontrack rollers 47 by apower screw drive 49 which includes avertical drive screw 51 journalled inbearings 53 mounted to theframe 3 of the printing and binding apparatus. The drive screw is rotary driven by an electric stepper motor M7 through a timing belt and pulley drive, as indicated at 55. In this manner, thenest 41 is moved to its raised position (not shown) at which location it receives the bound (but not yet trimmed) book B from thecarriage 7. With the book B received in and properly positioned relative to thenest 41, the stepper motor M7 is energized so as to rotate thedrive screw 51 which lowers thenest 41 from its raised to its lowered trimming positions (as shown inFig. 2 ). - The
nest 41 includes abook clamp 57, as best shown inFigs. 5 ,7 , and8 , for holding the bound book B while one or more edges thereof are trimmed. The details of thebook clamp 57 and thenest 41 will be more fully described hereinafter. However, thebook clamp 57 includes an indexing mechanism, as generally indicated at 99 (which is also described hereinafter), that operates to rotate the book B held in thenest 41 through various angles (or through any desired angle) from a first position in which a first edge or trim margin TM1 of the book B is trimmed, to a second in which the book is rotated to a set position, for example rotated 90° such that a second edge or trim margin TM2 of the book is in position such that it may be trimmed, and then to a third position in which the book is rotated to another set position, for example rotated an additional 90° such that a third edge or trim margin TM3 of the book may be trimmed. Finally,book clamp 57 may be retracted or opened to release the trimmed book B. - As generally indicated at 59, a book shear or trimmer is provided which may be adjustably moved into operating relation with a book held in the
nest 41 for trimming one, two, or three sides or edges of the book. Preferably, thetrimmer 59 is a knife shear of sufficient length to trim the lengthwise dimension of the largest book B to be bound and trimmed by theapparatus 1 of the present invention. Thetrimmer 59 is vertically mounted on atrim carriage 61 which is mounted for horizontal movement toward and away from an edge of the book B held in thenest 41 such that the horizontal position of the trimmer (and more particularly the vertical plane of the blade of the trimmer) relative to the edge of the book being trimmed determines the amount of the margin of the book B to be trimmed. Of course, the horizontal position of the trim carriage 61 (and hence the position of the trimmer 59) is under the control of thecontrol system CONT 1, as will be explained. - As best shown in
Figs. 6 and7 , thetrimmer 59 comprises atrimmer frame 62 in which a guillotine-type shear blade 63 having a shear edge 64 (as shown inFig. 7 ) is mounted to move between a fully open position and a closed trimming position. The trimmer further comprises ananvil 65 against which the book B in the area to be trimmed rests and against which theblade edge 64 cuts through the upper face of the cover C, the pages P of the book block BB, and through the other face of the cover to trim an edge or margin of the bound book B. The trimmer further has abook clamp 67 which is operable independently of thetrimming blade 63 for firmly holding the book relative to the trimming blade adjacent the trim line (i.e., the line along which theblade 63 will trim the edge of the book upon closing of the trim blade 63) to insure that the trim blade uniformly trims the edge of the book being trimmed. - Movement of the
trim blade 63 between its open and closed positions is power operated by means of a fluid cylinder, as indicated at 69 (seeFigure5 ). Further, theclamp 67 is power driven by another fluid cylinder 71. Each of these fluid cylinders is preferably hydraulic, but those skilled in the art will recognize that pneumatic cylinders or other devices may be used. Each of thefluid cylinders 69, 71 is supplied hydraulic fluid under pressure from a dedicated unitary hydraulic pump/electric motor (not shown). Such pumps may be driven in forward or reverse directions to reverse the pressure supplied to thecylinders 69, 71 so as to reverse their direction of movement. Thus, opening and closing of the shear blade and the shear clamp may be controlled (initiated) merely by reversing the operation of the pumps without the need for any expensive hydraulic valves or the like. Of course, those skilled in the art will recognize that many other arrangements for supplying hydraulic fluid under pressure to thefluid cylinders 69 and 71 may be used and that pneumatic, electromechanical, and/or other means could be used in place of the fluid cylinders themselves. - As noted, the
trimmer 59 is mounted on thetrim carriage 61 for movement in the horizontal direction toward and away from an edge of the book B being trimmed as the book is held in thenest 41. More specifically, thetrim carriage 61 is mounted ontrack rollers 73 which roll on atrim carriage track 75 that is rigidly mounted to theframe 3 for movement of the trimmer between a retracted position (as shown inFig. 6 ) where the trimmer will be clear of the maximum size book that can be trimmed. In the retracted position, the book can be rotated in the apparatus into a trimming position as it is held in thenest 41 for presenting another edge or margin of the book to the trimmer for being trimmed. In the trimming position, the plane of theshear blade 63 is accurately positioned with respect to a margin of the book B to be trimmed. Thetrim carriage 61 is power driven by apower drive 77 for movement between its retracted and trimming positions. Thepower drive 77 is shown to comprise an electric stepper motor M8 which drives adrive screw 79 by means of a belt andpulley arrangement 81. Thedrive screw 79 is journalled with respect to thetrim track 75 by means ofbearings 83. Under the control of thecontrol system CONT 1 of the present invention, the stepper motor M8 is controlled so as to accurately position (e.g., to within ± 0.0127 cm (0.005 inches)) the cutting plane of theshear knife 63 relative to the margin of the book B to be trimmed such that a predetermined trim margin TM is removed from the book B along the vertical edge of the book presented to the trim blade. - The
trimmer 59 described above is the trimmer described in myU. S. Patent 6,193,458 , which is herein incorporated by reference. It will be understood, however, that while such a trimmer works well in this instance, a trimmer, as disclosed in my pendingU. S. Patent Application No. 09/960,148 , which is herein incorporated by reference, may be used as well. In particular, it will be understood the blade and actuation system of this last-mentioned U. S. Patent Application may be used in place of theblade 63 and blade actuation system, as above. - As shown best in
Fig. 7 , thebook clamp 57 carried by thenest 41 comprises a fluid piston/cylinder actuator 85 having abook pressing platen 87 on its inner end for pressing against one face of the book B deposited within thenest 41. Thefluid cylinder 85 is powered by a unitary pump/electric motor (not shown) similar to the above described pump/electric motors used to supply fluid pressure to thecylinders 69, 71 described above. Thepressing platen 87 is journalled on the rod of thecylinder 85 by means of abearing 89 so as to readily permit rotation of the book B with respect to the cylinder as the book B is held in clamped relation with theplaten 87 when the book is in thenest 41 so as to permit a second and then a third margin of the book to be rotated into position for being trimmed by theblade 63. Thenest 41 includes alower reference surface 91 for engagement with the spine S of the book B as the book is deposited within the nest. The nest further has awall 93 extending upwardly from thesurface 91 which bears against a vertical face of the bound book B. Thiswall 93 is mounted on arotary shaft 95 that is mounted inbearings 97 carried by anelevator 43. As shown inFig. 8 , upon pressurization of thecylinder 85,platen 87 is forcefully moved inwardly toward the book B held in thenest 41 to thereby firmly grip the book between theplaten 87 and thevertical wall 93 which in turn is rotatably mounted on theshaft 95 which is carried by thebearings 97. In this manner, the book B is firmly held in place within thenest 41, thereby enabling positioning of theblade 63 relative to the known position of the book in the book nest to enable a predetermined trim margin TM1-TM3 to be trimmed from each of three respective margins or sides of the book B. - Preferably, the book B is positioned in the
nest 41 such that the geometric center of the finished book is coaxial with the centerline of thebook clamp cylinder 85 and theshaft 95 such that, as the book is rotated, the book will rotate about the axis of the finished book (i.e., the center of the book as trimmed). - As shown best in
Figs. 6 and7 , theindex drive 99 is mounted on theelevator 43 for indexing the shaft in increments of 90° so as to rotate the book B held within thenest 41 through a predetermined angle (e.g., 90°) about the horizontal axis of theshaft 95 to present a second and then a third edge of the book B for being trimmed by theblade 63. More specifically, the index drive is a stepper motor M9 connected to theshaft 95 by means of abelt 103 and pulley arrangement. Upon energization of the stepper motor M9 for a predetermined number of counts by thecontrol system CONT 1, the shaft 95 (and hence the book B) rotates a 90° such that another edge or margin of the book B is rotated to assume a vertical position where a predetermined trim margin for that edge or side of the book B may be trimmed by thetrimmer 61. It should be understood that other arrangements for indexing the book B may be used. For example, a hydraulically driven index mechanism may be used to rotate the book through angles of 90° or through other desired angles. For example, the book could be rotated through 180° between trimming of the top and bottom margins of the book without the trimming blade being horizontally repositioned. In addition, multiple trimming blades could be used to trim the book margins simultaneously. - Referring to
Fig. 6 , as shown within the phantom line circle, a range of sizes of books B held by thenest 41 is depicted that can be accommodated by the trimming station TS of the present invention. As shown, both the smallest and largest sizes of the books B accommodated by the apparatus of this invention is shown with the spine S of such books B bearing on the upper face of thenest surface 91, thereby properly positioning the book in heightwise orientation relative to theshear blade 63. The phantom line circle depicts the swing of the largest size book as the book is rotated from the first position to the second and then the third positions. - With the book positioned within
nest 41 in the first position such that the book's leading vertical edge and its trim margin TM1 are disposed toward theshear 59, thecontrol system CONT 1 operates to energize stepper motor M8 an amount so as to moveshear trimmer 59 horizontally from its retracted position (as shown inFig. 6 ) to a predetermined trimming position in which the vertical cutting plane of the trimmer is oriented such that the trimmer will shear the trim margin TM1 from the book. With theshear 59 in this first trimming position, the pump PM2 is energized so as to close theshear clamp 67 on the book to firmly hold the book while the trim margin TM1 is sheared from the book. Then, the shear pump PM1 is energized so as to actuate thecylinder 69 to forcefully move theblade 63 from its open position to its closed position so as to cut the desired trim margin TM1 from the book. After the shearing operation is complete, the pump motors PM1,PM 2 are energized in a reverse direction so as to open the clamp and move the shear blade to its open position. - After trimming of the first trim margin TM1, the stepper motor M8 is energized so as to horizontally move the
trim carriage 61 back to its retracted position from its cutting position. After theshear 59 is clear of the book circle, the stepper motor M9 is energized so as to index the nest 41 (and hence the book held therein) 90° about the horizontal axis of theshaft 95 to dispose a second edge or trim margin TM2 of the book in a vertical position. Thecontrol system CONT 1 is provided with information so as to calculate the shear plane of theshear 59 in relation to the book, as discussed above, so that the second trim margin TM2 may be trimmed from the book. With the book rotated to this second position, the stepper motor M8 is energized to move thetrim carriage 61 in the horizontal direction toward the book so that the shear plane of theblade 63 is positioned where theshear 59 can remove the second trim margin TM2 from the book. Again, pump PM2 is energized to actuate theshear clamp 67 and then the shear pump PM1 is energized so as to trim the second trim margin TM2 from the book. Once again, the pump motors PM1,PM 2 are energized so as to open the clamp and move the shear blade into its open position and the stepper motor M8 is energized so as to horizontally move thetrim carriage 61 clear of the book. Finally, the book is indexed through another 90° angle so as to position a third edge or trim margin TM3 of the book in a vertical position disposed toward thetrim blade 63. In the manner heretofore described, the shear carriage is moved inwardly toward the book and the vertical plane of the shear blade is positioned so as to trim the third trim margin TM3 from the book, thereby forming a book having three trimmed edges and an accurate, predetermined size. After the trimming is complete, the shear carriage is moved to its retracted position where it is clear of the book and the nest clamp cylinder is retracted to thereby release the book. - It should be noted that it may not always be required to return the
trimmer 59 to its retracted position after trimming of each edge of the book and that the trim carriage may be maintained in substantially its trimming position, moving only a minimal distance while the book is rotated from one trimming position to another. By not having to retract and advance the trimmer fully between its trim and retracted positions when trimming each edge of the book, the time required for trimming the book may be reduced. Furthermore, by moving the trimmer only a minimal amount, as needed during the rotation of the book, the book can remain positioned between theshear clamp 67 of the trimmingcarriage 61, albeit without the shear clamp firmly grasping the book, as the book is rotated. This prevents the opposite faces of the book cover from naturally splaying apart and where they could possibly fail to reenter theshear clamp 67. - An alternative embodiment of the printing and binding apparatus of the invention is shown in
Figs. 21-24 . The alternative embodiment of the printing and binding apparatus incorporates a second, bookpage printer assembly 200 attached to the printing andbinding apparatus 1 at a location along workpath WP separate from the location of the first textpage printer assembly 110. For example, the second textpage printer assembly 200 may be located at the opposite end of the workpath WP from the first described bookpage printer assembly 110. In operation, the second, bookpage printer assembly 200 functions similar to the first book page printer assembly and is configured to print and initially collate the pages of a book block and to load them into thecarriage 7 in substantially the same manner a the first bookpage printer assembly 110. Use of the second, bookpage printer assembly 200 increases the production rate of perfect bound books produced by the printing andbinding apparatus 1 by effectively cutting in half the time required to print the pages of the book blocks. - The second,
book printer assembly 200 comprises aprinter 202 and atransfer mechanism 204. Theprinter 202 of the second,book printer assembly 200 is preferably a black and white printer that is identical to theprinter 110 of the first, book page printer assembly described above. It should be understood, however, that theprinter 202 of the second, bookpage printer assembly 200, could be any type of printer, including a color printer if so desired, and need not be identical to theprinter 110 of the first, book page printer assembly. Thesecond printer 202 is mounted to theframe 3 of the printing andbinding apparatus 1 adjacent the trimming station TS at the opposite end of the workpath WP from theprinter 110 of the first, book page printer assembly. Like the first, book page printer assembly, theprinter 202 of the second, bookpage printer assembly 200 is preferably mounted to the printing andbinding apparatus 1 by asupport platform 206 that is attached to theframe 3 of the printing and binding apparatus by a vertically hingedsupport member 208. In general, theprinter 202 of the second, bookpage printer assembly 200 functions identically to the printer of the first, book page printer assembly. - The
transfer mechanism 204 of the second, bookpage printer assembly 200 comprises arectangular tray 210 and asupport bracket 212. Thetray 210 is preferably a mirror image of the tray of the first, book page printer assembly and includes identical features such as a box shaped bin having first 214 and second 216 side walls, arear wall 218, and atop wall 220, a vibratingmechanism 222 for initial jogging and collating of the printed pages of the book block, and a screw driven clampingarm 224. Ashaft 226 is mounted to thesupport bracket 212 for rotation about the shaft's axis. Thetray 210 is mounted on the shaft for rotation with the shaft. Like a mirror image of theshaft 132 of the first, book page printer assembly, the leftmost end 228 of theshaft 226 of the second, book page printer assembly is oriented slightly above the oppositeright end 230 of the shaft such that the shaft andtray 210 are angled slightly from the horizontal. - Unlike the
transfer mechanism 112 of the first, book page printer assembly, thesupport bracket 212 of the second,transfer mechanism 204 is constructed with a C-shapedportion 232 of the bracket that supports the opposite ends of thetray shaft 226. The C-shapedportion 232 is mounted to theframe 3 of the printing andbinding apparatus 1 for pivoting movement about a vertical axis defined by amain support member 234 of the support bracket. This pivoting connection allows the C-shapedportion 232 of thebracket 212, along with thetray 210 mounted thereto, to swing between an operational position, as shown inFig. 21-23 , and a maintenance position, as shown inFig. 24 . In the maintenance position thetransfer mechanism 204 is easily accessed for servicing and the trimming station TM beneath the transfer mechanism is also more easily accessed for servicing. Alocking mechanism 236 is provided for releasably securing the C-shapedportion 232 of thebracket 212 in the operational position. - Due to the pivoting movement of the
tray 210 and the C-shapedportion 232 of thesupport bracket 212 with respect to the printing andbinding apparatus 1, the rotation of thetray shaft 226 with respect to the C-shaped portion of the support bracket is driven by an alternating current trayshaft drive motor 238 that is mounted directly to the C-shaped portion of the support bracket such that it can pivot therewith. When the C-shapedportion 232 of thesupport bracket 212 is in the operational position, the trayshaft drive motor 238 can be operated by thecontrol system CONT 1 to selectively rotate the shaft, together with thetray 210, between a printed page receiving position shown inFig. 22 and a book block depositing position shown inFig. 23 . - In operation, the
transfer mechanism 204 of the second, bookpage printer assembly 200 operates in a similar manner to thetransfer mechanism 112 of the first, book page printer assembly. Thus, thetransfer mechanism 204 receives pages from theprinter 202 of the second, bookpage printer assembly 200 with thetray 210 in the printed page receiving position, initially jogs and collates the printed pages of a book block, clamps the printed book block on the tray, rotates the tray to its book block depositing position, and releases the book block to allow the book block to fall into thecarriage 7, in the same manner as described above in reference to the first, book page printer assembly. - Unlike the
transfer mechanism 112 of the first, book page printer assembly, thetransfer mechanism 204 of the second, book page printer assembly rotates thetray 210 to its book block depositing position and releases the book block into thecarriage 7 when the carriage is at the opposite end of the workpath WP, adjacent the trimming station TS. Just prior to this point, thecarriage 7 will have deposited a bound book into thenest 41 of the trimming station TS and the carriage is therefore empty. Under the control ofcontroller CONT 1, the carriage is moved beyond trimming station TS to a position belowtransfer mechanism 204 to receive the book block printed by thesecond printer 200. Then, after the book block is received in the carriage, the carriage is returned to the opposite end of the workpath WP so as to convey the second book block to the jogging station JS, to the milling station MS, to the adhesive application station AS, to the binding station BS, and thence to the trimming station TS in a manner similar to that described in regard to the book block printed by thefirst printer 110. Of course, while these operations are being carried out on the second book block,printer 110 may be printing another book block. - A
horizontal positioning plate 240 is mounted to theprinter binding apparatus 1 in a position aligned with the tray of thesecond transfer mechanism 204 and just beneath thecarriage 7 when the carriage is positioned beneath thetransfer mechanism 204 of the second, bookpage printer assembly 200 as shown inFigs. 22-24 . When a book block is deposited into thecarriage 7 from thetransfer mechanism 204 of the second, bookpage printer assembly 200, the spine of the book block is supported on thepositioning plate 240 and then theclamping members carriage 7 are moved together to firmly hold the book block. The positioning plate can also be provided with vertically extending sides positioned outside and below the clampingmembers carriage 7 to prevent pages of the book block from slipping off of the positioning plate. Thepositioning plate 240 is at an elevation above that of thehorizontal plate 13 of the jogging station JS such that a book block deposited into thecarriage 7 by the second, bookpage printer assembly 200 is positioned higher in the carriage than a book block deposited into the carriage by the first, book page printer assembly. Thus, thepositioning plate 240 serves to establish the vertical orientation of the book block as the book block is moved by thecarriage 7 back along the workpath WP to the jogging station JS at the opposite end of the workpath. Positioning the book block higher in thecarriage 7 prevents the book block from contacting any components of the various work stations as it is brought to the jogging station JS. - Once the
carriage 7 arrives at the jogging station JS with the book block printed by the second, bookpage printer assembly 200, the clampingmembers carriage 7 are released to allow the book block to drop onto thehorizontal surface 13 of the jogging station JS. From this point, the pages of the book block are jogged and the book binding process proceeds in the same manner as it would if printed by the first book page printer assembly as described above. - Thus, by incorporating the second, book
page printer assembly 200 in the additional embodiment of the printing and binding apparatus of the invention, the production rate of perfect bound books can be increased by alternating the feeding of the carriage with a book block printed by either of the first and second, book page printer assemblies. The increased production rate should be apparent in situations where the printing of a book block requires more time than it takes thecarriage 7 to move along the work path from the jogging station JS to the opposite end of the work path and then return to the jogging station during the production of a perfect bound book. This is often the case when the books being bound have large numbers of pages. Incorporating the second, bookpage printer assembly 200 in the additional embodiment of the printing and binding apparatus also allows the printing and binding apparatus to continue production of perfect bound books when either of the printers of the first and second, book page printer assemblies is being serviced. - As mentioned above, the second, book
page printer assembly 200 is positioned adjacent the trimming station TS which periodically requires maintenance. To perform such maintenance, it is helpful to have access to the trimming station TS from above. This is why the C-shapedportion 232 of thesupport bracket 212 is pivotable about themain support member 234 of the support bracket between the operational position and the maintenance position. As best shown inFig. 21 , themain support member 234 of thesupport bracket 212 is positioned adjacent the rear and right side of the C-shapedbracket 232. By releasing thelocking mechanism 236, the C-shapedportion 232 of thesupport bracket 212 and thetray 210 can be pivoted about themain support member 234 into the maintenance position as shown inFig. 24 . With the C-shapedportion 232 of thesupport bracket 212 and thetray 210 in the maintenance position, the top of the trimming station TS can be easily accessed for maintenance. Finally, when such maintenance is complete, the C-shapedportion 232 of thesupport bracket 212 and thetray 210 can be quickly pivoted back into the operational position and the printing and binding apparatus returned to production. - As noted, the binding and trimming
apparatus 1, as shown inFigs. 1 - 9 , is controlled by aprogrammable controller CONT 1.CONT 1 is preferably a programmable controller, such as an AT6400 controller, as described in the aforementionedU. S. Patent 6,193,458 and as illustrated inFig. 12 thereof. Thecontroller CONT 1 for the printing, binding and trimming apparatus, as shown inFigs. 14 - 25 , in turn controls operation of the black andwhite printer 110 via acontroller CONT 2 and of operation of black andwhite printer 200 via acontroller CONT 3. Operation ofcolor printer 114 is controlled by afourth controller CONT 4. For example, controllers CONT 2 - 4 may be model RPC-150 programmable controllers commercially available from Remote Processing Corporation, 7975 E. Harvard Avenue, Denver, Colorado 80231. - As previously noted, the apparatus of this invention is intended for printing, binding and trimming perfect bound books on demand. That is, such on demand printed books are stored in a digital library in a variety of digital formats. For example, the test pages of the books may be scanned and stored in a bit mapped format, or they stored in a PDF or other widely used format. The covers for the books are also stored in the digital library. Such covers may also be stored in a variety of formats. The digital library is typically stored on a so-called book server computer (not shown) and may be controlled by a book director computer program, the essential details of which are disclosed below. As described in the above-noted
U. S. Patent 5,465,213 , the book server may be located proximate the apparatus of this invention or may be located remotely and connected over a wide area network, such as the Internet. Persons may access the system to order a book to be printed on demand in a variety of ways. One preferred way would be to allow an internet connection such that a customer could access the book server remotely, view the books in the digital library, and upon choosing a book, ordering the book and commanding the apparatus of the present invention to print, bind and trim the selected book. - The control logic for operating a printing, binder, trimmer apparatus, as shown in
Fig. 21 , will be understood by one of ordinary skill in the art from the following listing of the basic programming steps: - 1.
CONT 1 determines the number ofbook block printers - 2.
CONT 1 signals (by placing a control file) the book director program on a book server, which black and whitebook block printer - 3. The book director program sends a pre-defined book "package" consisting of a book block printing script or text with the printer designated by 2 to the print spooler of the selected
printer cover printer 114 designated to the print spooler and a control file containing the book finish parameters (e.g., number of pages, paper thickness, any vertical offset between the cover and the book block, and finish trim dimensions). - 4.
CONT 1, having determined which black and white book block printer is to receive the next book block, positions thecarriage 7 proximate to and monitorsport # 23 of thatprinter - 5. Upon receiving the job complete message at the monitored port,
controller CONT 1 moves thecarriage 7 fully into position at arespective printer CONT 1 that the block is in place. - 6. As the cover exits cover
printer 114, a signal is generated to signal thecover controller CONT 4 that the cover is withincover transport mechanism 116 and the cover controller is then able to deliver the printed cover to the binding station BS. - 7.
CONT 1 then monitors the cover printertransfer controller CONT 4 for a signal that it has placed the cover into place in the binder station BS. - 8. Upon notification that a book block BB is in place within
carriage 7 and that the cover is in place at the binding station BS,CONT 1 then movescarriage 7 to the jogging station JS and reads the control file sent in 3. - 9. Using the dimensions T1 - T5 incorporated in the control file, as above described, the trim margins TM1 - TM3 are determined.
- 10. The desired position of the cover C at the binding station BS are then determined such that that cover is centered with respect to book block spine S. The cover may be centered with respect to the spine S of the book block BB by energizing stepper motor M1100 to drive
rolls 186 if forward or rearward direction so as to accurately located the portion of cover C which is to be bound to spine S of its respective book block. It will also be understood that the cover may be located with respect to the spine of its book block by, upon printing of the cover, centering the material printed on the cover with respect to the cover stock. In this manner, the cover may be accurately positioned by bringing the leading edge of the cover C into engagement with a fixed stop. - 11. With
carriage 7 positioned at jogging station JS, the jogging station is energized and deenergized for a time sufficient to jog or vibrate pages P (about 1 - 3 seconds) so as to align the pages of the book block. - 12. During the jogging operation, the trailing edge of book block BB is insured to be in contact with
vertical carriage wall 21 thus accurately establishing the fore to aft position of the book block incarriage 7. - 13. With the book block BB properly positioned within the carriage, carriage clamp motor M2 is energized so as to close carriage clamps 11a, 11b.
- 14. Wait 5 seconds, and then energize motors M3 - M5.
- 15. Energize Carriage Stepper Motor M1 to drive
carriage 7 from Jogging Station JS to Mill Station MS. As the carriage approaches Mill Station MS, themill head 31 is energized so as to roughen the spine of the book block as the latter is conveyed past the mill station. - 16.
