Definitions
- the present invention relates to a lamination book binding machine for binding plural printed sheets folded to have printed surfaces facing each other inside into a book by bonding the sheets together with glue applied on the outer surfaces of the sheets.
- One known book binding method of making albums with photos or the like, photo books, atlases, picture books, copy books of design drawings, etc. involves applying glue on one outer surface of printed sheets folded to have printed surfaces facing each other, and bonding successively stacked sheets together.
- a paper laminator of Patent Document 1 a plurality of vacuum rollers arranged in an up and down direction are used when bonding folded sheets together after glue application, the vacuum rollers applying suction to the sheets as they rotate so as to guide the sheets constantly until the sheets are bonded together. This lowers the possibility of sheets springing back after they are dropped even though they are fed at high speed, whereby the sheets can be bonded together with their ends closely aligned with each other.
- the glue-applied sheets are then slid on a rail to a lamination position, to be pressed with a press plate and bonded together.
- a half-folding/glue-applying book binding machine of Patent Document 2 uses a half-folding mechanism for folding rectangular sheets in half, a glue application mechanism for applying glue on the half-fold sheets, and a pressing means for pressing and bonding together the half-fold sheets stacked upon a table, to automate the process from the half-folding step to the bonding step.
- This book binding apparatus uses a pair of paper width restricting guides disposed in a V shape so as to guide left and right side edges of half-fold sheets fed from a glue application roller that forms part of the glue application mechanism after glue has been applied. These align both ends of the half-fold sheets stacked successively upon one another on the table.
- the present invention has been devised in view of such conventional problems and directed to providing a lamination book binding machine capable of properly binding half-fold printed sheets into a book.
- a first aspect of the present invention resides in a lamination book binding machine for binding a plurality of half-fold printed sheets (hereinafter referred to simply as printed sheets) folded to have printed surfaces facing each other inside into a book by bonding the printed sheets together, the machine including:
- a second aspect of the present invention resides in a lamination book binding machine for binding a plurality of half-fold printed sheets (hereinafter referred to simply as printed sheets) folded to have printed surfaces facing each other inside into a book by bonding the printed sheets together, the machine including:
- the lamination book binding machine uses a pair of plate springs when binding half-fold printed sheets into a book using the glue application roller, the pressure roller, the plurality of suction rollers, and the thrust-out press plate, so as to prevent the printed sheet fed out onto the rail by the plurality of suction rollers from springing back, and to prevent the printed sheet on which glue has been applied from springing back due to redundant glue on the rail when thrust out by the thrust-out press plate.
- printed sheets mean half-fold printed sheets.
- the plate spring of the present invention is formed by bending a thin plate spring material and includes a base portion fixed to a frame and a bent contact portion formed by bending the material to incline relative to the base portion such that the distance between the plate springs is reduced in a feeding direction of the printed sheet.
- half-fold printed sheets are inserted in between the glue application roller and the pressure roller.
- glue is applied on one outer surface of the printed sheets by rotation of the glue application roller and the pressure roller.
- the printed sheet with glue applied thereon is fed out to the plurality of suction rollers, which feed it out onto the rail.
- the bent contact portions of the pair of plate springs make contact with both side edges of the printed sheet, and as they deform elastically, the plate springs guide the printed sheet being fed out to a predetermined position in the width direction. With the pair of plate springs being maintained in the elastically deformed state, the printed sheet is prevented from springing back even after being fed onto the rail by the suction rollers in a manner in which it is prevented from springing back.
- the printed sheet fed out onto the rail is thrust out by the thrust-out press plate to a predetermined lamination position and bonded to a previously thrust out printed sheet.
- the pair of plate springs making contact with the printed sheet are maintained in the elastically deformed state so that the printed sheet is guided by the pair of plate springs such as to make tight contact with the rail as it is thrust out to the lamination position. Accordingly, even if some glue had dripped from the outer surface of the printed sheet and adhered on the rail, the printed sheet can be prevented from springing back from the rail as it is moved by the thrust-out press plate to be bonded to the previously thrust out printed sheet, because of the bent contact portions of the pair of plate springs making contact with both side edges of the printed sheet. Therefore, when the printed sheet thrust out by the thrust-out press plate is bonded to the previously thrust out printed sheet at the lamination position, the folded ends and both side edges of respective printed sheets can be aligned effectively at a predetermined position in the width direction.
- the lamination book binding machine provides one way of preventing printed sheets, particularly when the paper used for the printed sheets is thin or soft, from deflecting when sucked by the suction rollers.
- half-fold printed sheets are inserted in between the glue application roller and the pressure roller.
- glue is applied on the outer surface of the printed sheets by rotation of the glue application roller and the pressure roller.
- the printed sheet with glue applied thereon is fed out to the plurality of suction rollers, which feed it out onto the rail.
- the pair of wires with a tension applied by the tension applying means press down the printed sheet near both side edges thereof against the suction rollers.
- the printed sheet can be prevented from deflecting and losing its flat shape.
- the printed sheet fed out onto the rail is thrust out by the thrust-out press plate to the predetermined lamination position and bonded to the previously thrust out printed sheet.
- the thrust-out press plate deflects the printed sheet as it thrusts out the sheet from between the wires and the suction rollers.
- the printed sheet can thus be thrust out from between the wires and the suction rollers without the wires and tension applying means being moved specifically for that purpose. Therefore, when the printed sheet thrust out by the thrust-out press plate is bonded to the previously thrust out printed sheet at the lamination position, the printed sheets can be bonded to each other correctly without any wrinkles or the like.
- the pair of plate springs should preferably be configured to generate elastic deformation force by elastically deforming in the bent contact portion and a downstream portion in the feeding direction of the base portion, so that a reaction force that acts on the printed sheet when it is received by the rail causes tips of the bent contact portions of the pair of plate springs to bite into both side edges of the printed sheet, this biting state being maintained as the thrust-out press plate thrusts out the printed sheet in tight contact with the rail.
- the folded end of the printed sheet can be brought into tight contact with the rail by the pair of plate springs, and both side edges of the printed sheet can effectively be guided to a predetermined position in the width direction.
- the aforementioned lamination book binding machine can be configured to bind a book with paperboard interposed between the printed sheets, such that the rail includes a receiving position change part capable of receiving paperboard fed out from the plurality of suction rollers at a position higher than an upper surface of the rail, and that the paperboard received on the receiving position change part is thrust out by the thrust-out press plate to be bonded to a previously thrust out printed sheet on the rail at a position separated a predetermined distance from the folded end of the printed sheet.
- the lamination book binding machine is capable of binding a book in both cases of bonding printed sheets together and bonding printed sheets together with paperboard interposed therebetween.
- the receiving position change part may be fixed to a certain height position, or may be moved up and down alternately when bonding printed sheets and paperboard together. Thereby the machine can flexibly be adapted to binding of various types of books in accordance with the material, thickness, or the like of the paperboard.

- an acetic acid emulsion glue 83 is used for bonding the printed sheets 8 of this embodiment.
- Using the paperboard 80 can improve absorption of moisture in the glue 83 applied on the printed sheets 8, whereby inexpensive acetic acid emulsion glue 83 can be made easier to use.
- the rail 6 of this embodiment has a receiving position change part 61 that enables paperboard 80 fed out from the plurality of suction rollers 4 to be received at a higher position than the upper surface of the rail 6.
- the receiving position change part 61 can be moved up and down via a hole or the like cut out in the rail 6.

- the paperboard 80 is bonded to the printed sheet 8 at a position separated a predetermined distance from the folded end 801 as shown in FIG. 9 , and thus a book can be bound by alternately bonding paperboard 80 and printed sheets 8.
- the configuration of this embodiment using the pair of plate springs 5 prevents book binding failures due to adverse effects of glue adhered on the rail 6 from occurring.
- half-fold printed sheets 8 are inserted into the gap formed between the drums 31, the plurality of sheet feeding rollers 34, the glue application roller 32, and the pressure roller 33 in a way to allow the folded ends 801 to reach the gap first, and glue is applied on one outer surface 82A of the printed sheets 8 by rotation of the drums 31, the plurality of sheet feeding rollers 34, the glue application roller 32, and the pressure roller 33.
- the printed sheet 8 with glue applied thereon is fed out to the plurality of suction rollers 4, which feed it out onto the rail 6.
- the tips of the bent contact portions 52 of the pair of plate springs 5 make contact with the printed sheet 8, and as they deform elastically, the plate springs 5 guide the printed sheet 8 being fed out to a predetermined position in the width direction (center position between the frames 2A).
- the plurality of suction rollers 4 prevent the printed sheet 8 from springing back.
- the reaction force that acts on the printed sheet 8 when it is received on the rail 6 causes the tips of the bent contact portions 52 of the pair of plate springs 5 to bite into both side edges 802 of the printed sheet 8 as shown in FIG. 7 . This maintains the pair of plate springs 5 in the elastically deformed state, so that the pair of plate springs 5 prevent the printed sheet 8 from springing back from the rail 6.
- the printed sheet 8 fed out onto the rail 6 is thrust out by the thrust-out press plate 71 to the predetermined lamination position 702 and bonded to the previously thrust out printed sheet 8.
- the pair of plate springs 5 making contact with the printed sheet 8 are elastically deformed such as to bite into both side edges 802 of the printed sheet 8, so that the printed sheet 8 is guided by the pair of plate springs 5 biting thereinto as it is thrust out to the lamination position 702.
- the printed sheet 8 can be prevented from springing back from the rail 6 as it is moved by the thrust-out press plate 71 to be bonded to the previously thrust out printed sheet 8, because of the tips of the bent contact portions 52 of the pair of plate springs 5 biting into both side edges 802 of the printed sheet 8. Therefore, when the printed sheet 8 thrust out by the thrust-out press plate 71 is bonded to the previously thrust out printed sheet 8 at the lamination position 702, the folded ends 801 and both side edges 802 of respective printed sheets 8 can be aligned effectively at a predetermined position in the width direction (center position between the frames 2A).
- half-fold printed sheets 8 can be bound into a book, with their end faces 801 and 802 being effectively aligned at respective positions.
- This embodiment shows one way of preventing printed sheets 8, particularly thin printed sheets 8, from deflecting (curling) when sucked by the suction rollers 4.
- the lamination book binding machine 1 of this embodiment includes, instead of the above-described pair of plate springs 5, as shown in FIG. 10 to FIG. 12 , a pair of wires 53 stretched to extend up and down at positions opposite the plurality of suction rollers 4, and a tension applying means 54 that applies a predetermined tension to the pair of wires 53.
- the wires 53 in this embodiment are a stainless wire with a diameter of 0.5 mm, and are stretched up and down on the pair of inner frames 2A at positions opposite the plurality of suction rollers 4 disposed on the frames 2A.
- the wires 53 are disposed close to both side edges 802 of the printed sheet 8, more specifically, at positions where they press down areas within 3 mm from the side edges 802 of the printed sheet 8.
- the wires 53 should preferably press down the printed sheet 8 at positions 1 to 1.5 mm from the side edges 802.
- the tension applying means 54 in this embodiment is a tension spring 54, which is attached respectively to the pair of wires 53.
- wire guides 55 are provided at an upper and lower position of the frames 2A for fixing the installation position of the wires 53.
- One end of the wire 53 is fixed to the wire guide 55 or frame 2A, while the other end of the wire 53 is attached to one end of the tension spring 54, the other end of the tension spring 54 being fixed to the frame 2A.
- Tension applied to the wire 53 can be adjusted to a target value by changing the spring constant of the tension spring 54.
- the lamination book binding machine 1 of this embodiment is configured such that, when the suction rollers 4 feed out a printed sheet 8, the wires 53 under a tension applied by the tension springs 54 press down the printed sheet 8 close to its both side edges 802 against the suction rollers 4. Further, the lamination book binding machine 1 of this embodiment is configured such that the thrust-out press plate 71 deflects the printed sheet 8 when it thrusts the sheet out from between the wires 53 and the suction rollers 4, as shown in FIG. 12 .
- thin copying paper of about 0.1 mm thickness is used as the printed sheets 8 for the book binding.
- the thickness of the printed sheets 8 can be from 0.08 to 0.12 mm. Paper with a thickness larger than 0.12 mm can also be used as the printed sheets 8 if the paper has a soft texture.
- Other elements of the lamination book binding machine 1 of this embodiment are the same as those of the previously described Embodiment 1.
- half-fold printed sheets 8 are inserted into the gap formed between the drums 31, the plurality of sheet feeding rollers 34, the glue application roller 32, and the pressure roller 33 in a way to allow the folded ends 801 to reach the gap first, and glue is applied on one outer surface 82A of the printed sheets 8 by rotation of the drums 31, the plurality of sheet feeding rollers 34, the glue application roller 32, and the pressure roller 33.
- the printed sheet 8 with glue applied thereon is fed out to the plurality of suction rollers 4, which feed it out onto the rail 6.
- the feeding force exerted by the suction rollers 4 acts on the printed sheet 8 and causes it to curl.
- the pair of wires 53 with a tension applied by the tension springs 54 press down the printed sheet 8 near its both side edges 802 against the suction rollers 4.
- the printed sheet 8 can be prevented from deflecting (losing its flat shape).
- the printed sheet 8 fed out onto the rail 6 is thrust out by the thrust-out press plate 71 to the predetermined lamination position 702 and bonded to the previously thrust out printed sheet 8.
- the thrust-out press plate 71 deflects the printed sheet 8 as it thrusts the sheet out from between the wires 53 and the suction rollers 4.
- the printed sheet 8 can thus be thrust out from between the wires 53 and the suction rollers 4 without the wires 53 and tension springs 54 being moved specifically for that purpose. Therefore, when the printed sheet 8 thrust out by the thrust-out press plate 71 is bonded to the previously thrust out printed sheet 8 at the lamination position 702, the printed sheets 8 can be bonded to each other correctly without any wrinkles or the like caused by paper deflection.

Abstract
Description
- The present invention relates to a lamination book binding machine for binding plural printed sheets folded to have printed surfaces facing each other inside into a book by bonding the sheets together with glue applied on the outer surfaces of the sheets.
- One known book binding method of making albums with photos or the like, photo books, atlases, picture books, copy books of design drawings, etc. involves applying glue on one outer surface of printed sheets folded to have printed surfaces facing each other, and bonding successively stacked sheets together. For example, in a paper laminator of
Patent Document 1, a plurality of vacuum rollers arranged in an up and down direction are used when bonding folded sheets together after glue application, the vacuum rollers applying suction to the sheets as they rotate so as to guide the sheets constantly until the sheets are bonded together. This lowers the possibility of sheets springing back after they are dropped even though they are fed at high speed, whereby the sheets can be bonded together with their ends closely aligned with each other. The glue-applied sheets are then slid on a rail to a lamination position, to be pressed with a press plate and bonded together. - A half-folding/glue-applying book binding machine of
Patent Document 2, for example, uses a half-folding mechanism for folding rectangular sheets in half, a glue application mechanism for applying glue on the half-fold sheets, and a pressing means for pressing and bonding together the half-fold sheets stacked upon a table, to automate the process from the half-folding step to the bonding step. This book binding apparatus uses a pair of paper width restricting guides disposed in a V shape so as to guide left and right side edges of half-fold sheets fed from a glue application roller that forms part of the glue application mechanism after glue has been applied. These align both ends of the half-fold sheets stacked successively upon one another on the table. -

2001-187491 - However, in binding printed sheets into a book, there can arise situations where the ends of printed sheets are not aligned because of adverse effects of glue transferred from the printed sheets and adhered onto the rail, or where, particularly when the paper used for the printed sheets is thin or soft, the printed sheets being fed by the vacuum rollers are curled when abutted on the rail because of the feeding force from the vacuum rollers. Since proper book binding cannot be achieved in such situations, appropriate countermeasures are necessary. In the above-mentioned
Patent Documents - The present invention has been devised in view of such conventional problems and directed to providing a lamination book binding machine capable of properly binding half-fold printed sheets into a book.
- A first aspect of the present invention resides in a lamination book binding machine for binding a plurality of half-fold printed sheets (hereinafter referred to simply as printed sheets) folded to have printed surfaces facing each other inside into a book by bonding the printed sheets together, the machine including:
- a glue application roller which applies glue to one outer surface of the printed sheet during rotation;
- a pressure roller which rotates with a constant gap between the pressure roller and the glue application roller so as not to press the printed sheet and feeds out the printed sheet downward together with the glue application roller;
- a plurality of suction rollers which suck the other outer surface of the printed sheet on which glue has been applied as the suction rollers rotate to feed out the printed sheet onto a rail;
- a pair of plate springs which make contact with both side edges of the printed sheet to guide the printed sheet to a predetermined position in a width direction and to prevent the printed sheet fed out onto the rail from springing back; and
- a thrust-out press plate which thrusts out the printed sheet fed out onto the rail to a predetermined lamination position to bond the printed sheet to a previously thrust out printed sheet,
- wherein the pair of plate springs are formed by bending a thin plate spring material and include a base portion fixed to a frame and a bent contact portion formed by bending the material to incline relative to the base portion such that the distance between the plate springs is reduced in a feeding direction of the printed sheet, and
- the pair of plate springs are contacted to both side edges of the printed sheet to cause elastic deformation in the pair of plate springs when the suction rollers feed out the printed sheet, so that the printed sheet is thrust out by the thrust-out press plate in tight contact with the rail, with the pair of plate springs being maintained in their elastically deformed state.
- A second aspect of the present invention resides in a lamination book binding machine for binding a plurality of half-fold printed sheets (hereinafter referred to simply as printed sheets) folded to have printed surfaces facing each other inside into a book by bonding the printed sheets together, the machine including:
- a glue application roller which applies glue to one outer surface of the printed sheet during rotation;
- a pressure roller which rotates with a constant gap between the pressure roller and the glue application roller so as not to press the printed sheet and feeds out the printed sheet downward together with the glue application roller;
- a plurality of suction rollers which suck the other outer surface of the printed sheet on which glue has been applied as the suction rollers rotate to feed out the printed sheet onto a rail;
- a pair of wires stretched up and down at positions opposite the plurality of suction rollers;
- a tension applying means for applying a predetermined tension to the pair of wires; and
- a thrust-out press plate which thrusts out the printed sheet fed out onto the rail to a predetermined lamination position to bond the printed sheet to a previously thrust out printed sheet,
- wherein the wires press down the printed sheet near both side edges thereof against the suction rollers when the suction rollers feed out the printed sheet, so that the thrust-out press plate deflects the printed sheet when thrusting out the printed sheet from between the wires and the suction rollers.
- The lamination book binding machine according to the first aspect of the present invention uses a pair of plate springs when binding half-fold printed sheets into a book using the glue application roller, the pressure roller, the plurality of suction rollers, and the thrust-out press plate, so as to prevent the printed sheet fed out onto the rail by the plurality of suction rollers from springing back, and to prevent the printed sheet on which glue has been applied from springing back due to redundant glue on the rail when thrust out by the thrust-out press plate. In the present invention, printed sheets mean half-fold printed sheets.
More specifically, the plate spring of the present invention is formed by bending a thin plate spring material and includes a base portion fixed to a frame and a bent contact portion formed by bending the material to incline relative to the base portion such that the distance between the plate springs is reduced in a feeding direction of the printed sheet. - In binding a book using the lamination book binding machine of the present invention, half-fold printed sheets are inserted in between the glue application roller and the pressure roller. At this time, glue is applied on one outer surface of the printed sheets by rotation of the glue application roller and the pressure roller.
The printed sheet with glue applied thereon is fed out to the plurality of suction rollers, which feed it out onto the rail. At this time, in the present invention, the bent contact portions of the pair of plate springs make contact with both side edges of the printed sheet, and as they deform elastically, the plate springs guide the printed sheet being fed out to a predetermined position in the width direction. With the pair of plate springs being maintained in the elastically deformed state, the printed sheet is prevented from springing back even after being fed onto the rail by the suction rollers in a manner in which it is prevented from springing back. - Next, the printed sheet fed out onto the rail is thrust out by the thrust-out press plate to a predetermined lamination position and bonded to a previously thrust out printed sheet. At this time, the pair of plate springs making contact with the printed sheet are maintained in the elastically deformed state so that the printed sheet is guided by the pair of plate springs such as to make tight contact with the rail as it is thrust out to the lamination position. Accordingly, even if some glue had dripped from the outer surface of the printed sheet and adhered on the rail, the printed sheet can be prevented from springing back from the rail as it is moved by the thrust-out press plate to be bonded to the previously thrust out printed sheet, because of the bent contact portions of the pair of plate springs making contact with both side edges of the printed sheet. Therefore, when the printed sheet thrust out by the thrust-out press plate is bonded to the previously thrust out printed sheet at the lamination position, the folded ends and both side edges of respective printed sheets can be aligned effectively at a predetermined position in the width direction.
- Therefore, with the lamination book binding machine according to the first aspect of the present invention, half-fold printed sheets can properly be bound into a book, with their end faces being effectively aligned at respective positions.
- The lamination book binding machine according to the second aspect of the present invention provides one way of preventing printed sheets, particularly when the paper used for the printed sheets is thin or soft, from deflecting when sucked by the suction rollers.
In binding a book using the lamination book binding machine of the present invention, too, half-fold printed sheets are inserted in between the glue application roller and the pressure roller. At this time, glue is applied on the outer surface of the printed sheets by rotation of the glue application roller and the pressure roller.
The printed sheet with glue applied thereon is fed out to the plurality of suction rollers, which feed it out onto the rail. At this time, in the present invention, the pair of wires with a tension applied by the tension applying means press down the printed sheet near both side edges thereof against the suction rollers. Thus the printed sheet can be prevented from deflecting and losing its flat shape. - Next, the printed sheet fed out onto the rail is thrust out by the thrust-out press plate to the predetermined lamination position and bonded to the previously thrust out printed sheet. At this time, the thrust-out press plate deflects the printed sheet as it thrusts out the sheet from between the wires and the suction rollers. The printed sheet can thus be thrust out from between the wires and the suction rollers without the wires and tension applying means being moved specifically for that purpose. Therefore, when the printed sheet thrust out by the thrust-out press plate is bonded to the previously thrust out printed sheet at the lamination position, the printed sheets can be bonded to each other correctly without any wrinkles or the like.
- Accordingly, with the lamination book binding machine according to the second aspect of the present invention, half-fold printed sheets can properly be bound into a book without any wrinkles or the like.

In the first aspect of the present invention, the pair of plate springs should preferably be configured to generate elastic deformation force by elastically deforming in the bent contact portion and a downstream portion in the feeding direction of the base portion, so that a reaction force that acts on the printed sheet when it is received by the rail causes tips of the bent contact portions of the pair of plate springs to bite into both side edges of the printed sheet, this biting state being maintained as the thrust-out press plate thrusts out the printed sheet in tight contact with the rail.
In this case, when feeding out the printed sheet onto the rail by the plurality of suction rollers, and when thrusting it out by the thrust-out press plate, the folded end of the printed sheet can be brought into tight contact with the rail by the pair of plate springs, and both side edges of the printed sheet can effectively be guided to a predetermined position in the width direction. - The aforementioned lamination book binding machine can be configured to bind a book with paperboard interposed between the printed sheets, such that the rail includes a receiving position change part capable of receiving paperboard fed out from the plurality of suction rollers at a position higher than an upper surface of the rail, and that the paperboard received on the receiving position change part is thrust out by the thrust-out press plate to be bonded to a previously thrust out printed sheet on the rail at a position separated a predetermined distance from the folded end of the printed sheet.
In this case, the lamination book binding machine is capable of binding a book in both cases of bonding printed sheets together and bonding printed sheets together with paperboard interposed therebetween. The receiving position change part may be fixed to a certain height position, or may be moved up and down alternately when bonding printed sheets and paperboard together. Thereby the machine can flexibly be adapted to binding of various types of books in accordance with the material, thickness, or the like of the paperboard. - Hereinafter, embodiments of the lamination book binding machine according to the present invention will be described with reference to the drawings.
- The lamination
book binding machine 1 of this embodiment binds a plurality of half-fold printed sheets 8 (hereinafter referred to simply as "printedsheets 8") folded to have printedsurfaces 81 facing each other inside into a book by bonding them together as shown inFIG. 1 ,FIG. 2 , andFIG. 8 .
The laminationbook binding machine 1 includes aglue application roller 32, apressure roller 33, a plurality ofsuction rollers 4, a pair of plate springs 5, and a thrust-outpress plate 71. - As shown in
FIG. 1 andFIG. 2 , theglue application roller 32 is configured to apply glue on oneouter surface 82A of printedsheets 8 as it rotates. Thepressure roller 33 is configured to rotate with a constant gap between itself and theglue application roller 32 so as not to press the printedsheet 8, and to feed out printedsheets 8 downward together with theglue application roller 32. As shown inFIG. 3 , the plurality ofsuction rollers 4 are configured to suck the otherouter surface 82B of glue-applied printedsheets 8 as they rotate so as to feed out printedsheets 8 onto arail 6 such as to prevent thesheets 8 from springing back. As shown inFIG. 3 ,FIG. 6 , andFIG. 7 , the pair of plate springs 5 are configured to make contact with both side edges 802 of the printedsheet 8 to prevent the printedsheet 8 fed out onto therail 6 from springing back, in cooperation with the plurality ofsuction rollers 4 preventing the spring back. As shown inFIG. 4 andFIG. 5 , the thrust-outpress plate 71 is configured to thrust out the printedsheet 8 fed out onto therail 6 to a predetermined lamination position 702 (thrusting direction is indicated by arrow G in these drawings), to bond it to a previously thrust out printedsheet 8. - The pair of plate springs 5 are formed of a thin plate spring material bent as shown in
FIG. 7 , and include abase portion 51 fixed to aframe 2A, and abent contact portion 52 formed by bending the material to incline relative to thebase portion 51 such that the distance between the plate springs 5 is reduced in the feeding direction F of the printedsheet 8. The laminationbook binding machine 1 is configured such that, when thesuction rollers 4 feed out a printedsheet 8, the pair of plate springs 5 are contacted against both side edges 802 of the printedsheet 8 to cause elastic deformation in the pair of plate springs 5, and the thrust-outpress plate 71 thrusts out the printedsheet 8 in tight contact with therail 6, with the pair of plate springs 5 being maintained in the elastically deformed state. - The lamination
book binding machine 1 of this embodiment will be described below in detail with reference toFIG. 1 to FIG. 9 .
As shown inFIG. 1 andFIG. 2 , the laminationbook binding machine 1 of this embodiment is configured such that half-fold printedsheets 8 are fed out downward through a gap between theglue application roller 32 and thepressure roller 33, and then fed out downwards while being sucked by the plurality ofsuction rollers 4 aligned in the up and down direction to be placed at a receiving position on therail 6. As shown inFIG. 4 andFIG. 5 , the thrust-outpress plate 71 is configured such as to slide the printedsheet 8 placed on the receiving position on therail 6 in the horizontal direction to be bonded to a previously pressed one of the plurality of printedsheets 8 pressed against anopposite plate 72.
The laminationbook binding machine 1 of this embodiment is configured so that the half-fold printedsheet 8 is delivered ontodrums 31 in a way to allow its foldedend 801 to make contact first with thedrums 31 and that the folded ends 801 are abutted on therail 6 to be aligned for the book binding. - As shown in
FIG. 1 andFIG. 2 , asheet stacking board 21 for stacking and storing collated half-fold printedsheets 8 is disposed above the laminationbook binding machine 1. To thesheet stacking board 21 is provided apaper suction member 22 that picks up by suction the lowermost printedsheet 8 one by one to take it out downwards. Thepaper suction member 22 includes paper suction parts at two or more locations. Below thepaper suction member 22 are rotatably arranged thedrums 31 that receive printedsheets 8 fed thereto by thepaper suction member 22 from thesheet stacking board 21 and feed them out. Opposite thedrums 31 are rotatably arrangedsheet feeding rollers 34 that hold the printedsheets 8 between themselves and thedrums 31 to feed them out. Additionalsheet feeding rollers 34 are arranged rotatably opposite each other below thedrums 31 and thesheet feeding rollers 34 so as to pinch and feed out the printedsheets 8. - The
glue application roller 32 is disposed below thedrums 31 and the plurality ofsheet feeding rollers 34. Theglue application roller 32 is in rotating contact with aglue roller 322 that is in contact withglue 83 inside aglue tank 321, via an adjustingroller 323 that adjusts the amount of appliedglue 83.
Therail 6 on which the thrust-outpress plate 71 and theopposite plate 72 are provided is configured so that they can accommodate size changes in the up and down direction of the printedsheets 8. Therail 6 can be moved up and down to be adjusted in accordance with the height position of the folded ends 801, while the upper end of the printedsheets 8 is maintained at a fixed height position. - The plurality of
suction rollers 4 aligned in the up and down direction rotate in synchronism with each other via a rotationdrive power source 43, atiming belt 44, and the like. They rotate at the same circumferential speed (feeding speed) as that of thedrums 31, the plurality ofsheet feeding rollers 34, theglue application roller 32, and thepressure roller 33.
The plurality ofsuction rollers 4 are arranged on left and right sides relative to the feeding direction F of the printedsheets 8, as shown inFIG. 2 . The thrust-outpress plate 71 is disposed such as to be slidable in the horizontal direction between the plurality ofsuction rollers 4. As shown inFIG. 4 , on therail 6, at a position opposite the thrust-outpress plate 71 is theopposite plate 72 that holds therail 6 with an upper and lower plate to keep its position by means of spring pressure. Theopposite plate 72 is configured to move back stepwise relative to the thrust-outpress plate 71 each time printedsheets 8 are bonded together so as to keep thelamination position 702 of the printedsheets 8 at the same position. - As shown in
FIG. 3 andFIG. 6 , thesuction rollers 4 are configured to have cylindricalrotating parts 42 formed with a plurality of circumferentially arranged throughholes 421, which are rotated and slid on the outer circumference ofcolumnar core parts 41 formed withsuction passages 411.
Suction pipes connected to a vacuum pump or the like are attached to the entrance of thesuction passages 411 of thecolumnar core parts 41, while the exit of thesuction passages 411 is formed on the side opposite the printedsheet 8. Suction is applied by the vacuum pump or the like, and as thecolumnar core parts 41 are rotated to feed out a printedsheet 8, the printedsheet 8 is sucked when the throughholes 421 of the cylindricalrotating parts 42 come to face the exit of thesuction passages 411, while the printedsheet 8 is not sucked when the remainder of the cylindricalrotating parts 42 comes to face the exit of thesuction passages 411. Thereby suction force is applied only to necessary portions and a drop in the vacuum degree (suction force) caused by unnecessary air drawing can be prevented. - As shown in
FIG. 3 andFIG. 7 , the pair of plate springs 5 of this embodiment are fixed to theframes 2A at upper ends of theirbase portions 51. The pair of plate springs 5 are configured to generate an elastic deformation force due to elastic deformation of thebent contact portions 52 and downstream portions in the feeding direction F of thebase portions 51 when a printedsheet 8 is inserted. The pair of plate springs 5 are attached to theframes 2A using the space in between thesuction rollers 4 in the up and down direction. - The pair of plate springs 5 of this embodiment are attached at a plurality of positions in the up and down direction between the plurality of
suction rollers 4. The pair of plate springs 5 can be abutted against the printedsheet 8 fed out by the plurality ofsuction rollers 4 at one or a plurality of positions in the up and down direction.
The pair of plate springs 5 are formed to have a length along the horizontal direction to guide the printedsheet 8 thrust out by the thrust-outpress plate 71 to immediately before thelamination position 702. When printedsheets 8 are fed out by thesuction rollers 4 and thrust out by the thrust-outpress plate 71, one each printedsheet 8 is brought into contact with the pair of plate springs 5. - As shown in
FIG. 2 , the plurality ofsuction rollers 4 and the pair of plate springs 5 of this embodiment are provided to theinner frames 2A disposed on the inner side ofouter frames 2B. Thedrums 31, theglue application roller 32, thepressure roller 33, and the plurality ofsheet feeding rollers 34 are disposed on theouter frames 2B. - As shown in
FIG. 4 , the thrust-outpress plate 71 is configured to wait at a retractedposition 701 where it is retracted from the plurality ofsuction rollers 4 until a printedsheet 8 is fed out onto therail 6 by thesuction rollers 4 and others, and after the printedsheet 8 is fed out onto therail 6, thrust out this printedsheet 8 to thelamination position 702 to bond it to the previously thrust out printedsheet 8 held on theopposite plate 72. - As shown in
FIG. 7 , the laminationbook binding machine 1 of this embodiment is configured such that the reaction force that acts on the printedsheet 8 when it is received by therail 6 causes tips of thebent contact portions 52 of the pair of plate springs 5 to bite into both side edges 802 of the printedsheet 8, this biting state being maintained as the thrust-outpress plate 71 thrusts out the printedsheet 8 in tight contact with therail 6.
The pair of plate springs 5 are maintained in the state in which they bite into both side edges 802 of the printedsheet 8 so that the foldedend 801 of the printedsheet 8 remains in tight contact with therail 6 until the moment when the printedsheet 8 is bonded by the thrust-outpress plate 71. - The lamination
book binding machine 1 of this embodiment is capable of binding only the printedsheets 8 into a book by bonding them together, as shown inFIG. 8 , and also capable of binding printedsheets 8 withpaperboard 80 interposed therebetween into a book by bonding them together, as shown inFIG. 9 .
For bonding the printedsheets 8 of this embodiment, for example, an aceticacid emulsion glue 83 is used. Using thepaperboard 80 can improve absorption of moisture in theglue 83 applied on the printedsheets 8, whereby inexpensive aceticacid emulsion glue 83 can be made easier to use. - As shown in
FIG. 4 andFIG. 9 , therail 6 of this embodiment has a receiving position changepart 61 that enablespaperboard 80 fed out from the plurality ofsuction rollers 4 to be received at a higher position than the upper surface of therail 6. The receiving position changepart 61 can be moved up and down via a hole or the like cut out in therail 6. InFIG. 9 , the upper surface of the receiving position changepart 61 when bonding printedsheets 8 is indicated and labeled as 601, while the upper surface of the receiving position changepart 61 when bondingpaperboard 80 is indicated and labeled as 602. - When bonding together the printed
sheets 8 withpaperboard 80 interposed therebetween, the laminationbook binding machine 1 of this embodiment thrusts out thepaperboard 80 received on the upper surface of the receiving position changepart 61 by the thrust-outpress plate 71 to bond it to the previously thrust out printedsheet 8 on therail 6. Thereby, thepaperboard 80 is bonded to the printedsheet 8 at a position separated a predetermined distance from the foldedend 801 as shown inFIG. 9 , and thus a book can be bound by alternately bondingpaperboard 80 and printedsheets 8. - If the glue on the
outer surface 82A of the printedsheet 8 adheres on the surface of therail 6 when the printedsheet 8 after glue has been applied thereto is placed on therail 6, there is a possibility that the glue adhered on therail 6 may cause slip resistance and deteriorate the sliding properties of the printedsheet 8 when the thrust-outpress plate 71 thrusts out the printedsheet 8.
In this regard, the configuration of this embodiment using the pair of plate springs 5 prevents book binding failures due to adverse effects of glue adhered on therail 6 from occurring. - In binding a book using the lamination
book binding machine 1 of this embodiment, half-fold printedsheets 8 are inserted into the gap formed between thedrums 31, the plurality ofsheet feeding rollers 34, theglue application roller 32, and thepressure roller 33 in a way to allow the folded ends 801 to reach the gap first, and glue is applied on oneouter surface 82A of the printedsheets 8 by rotation of thedrums 31, the plurality ofsheet feeding rollers 34, theglue application roller 32, and thepressure roller 33.
The printedsheet 8 with glue applied thereon is fed out to the plurality ofsuction rollers 4, which feed it out onto therail 6. At this time, in this embodiment, the tips of thebent contact portions 52 of the pair of plate springs 5 make contact with the printedsheet 8, and as they deform elastically, the plate springs 5 guide the printedsheet 8 being fed out to a predetermined position in the width direction (center position between theframes 2A). When the printedsheet 8 abuts on therail 6, the plurality ofsuction rollers 4 prevent the printedsheet 8 from springing back. Also, the reaction force that acts on the printedsheet 8 when it is received on therail 6 causes the tips of thebent contact portions 52 of the pair of plate springs 5 to bite into both side edges 802 of the printedsheet 8 as shown inFIG. 7 . This maintains the pair of plate springs 5 in the elastically deformed state, so that the pair of plate springs 5 prevent the printedsheet 8 from springing back from therail 6. - Next, the printed
sheet 8 fed out onto therail 6 is thrust out by the thrust-outpress plate 71 to thepredetermined lamination position 702 and bonded to the previously thrust out printedsheet 8. At this time, the pair of plate springs 5 making contact with the printedsheet 8 are elastically deformed such as to bite into both side edges 802 of the printedsheet 8, so that the printedsheet 8 is guided by the pair of plate springs 5 biting thereinto as it is thrust out to thelamination position 702.
Accordingly, even if someglue 83 had dripped from theouter surface 82A of the printedsheet 8 and adhered on therail 6, the printedsheet 8 can be prevented from springing back from therail 6 as it is moved by the thrust-outpress plate 71 to be bonded to the previously thrust out printedsheet 8, because of the tips of thebent contact portions 52 of the pair of plate springs 5 biting into both side edges 802 of the printedsheet 8. Therefore, when the printedsheet 8 thrust out by the thrust-outpress plate 71 is bonded to the previously thrust out printedsheet 8 at thelamination position 702, the folded ends 801 and both side edges 802 of respective printedsheets 8 can be aligned effectively at a predetermined position in the width direction (center position between theframes 2A). - Accordingly, with the lamination
book binding machine 1 of this embodiment, half-fold printedsheets 8 can be bound into a book, with their end faces 801 and 802 being effectively aligned at respective positions. - This embodiment shows one way of preventing printed
sheets 8, particularly thin printedsheets 8, from deflecting (curling) when sucked by thesuction rollers 4.
The laminationbook binding machine 1 of this embodiment includes, instead of the above-described pair of plate springs 5, as shown inFIG. 10 to FIG. 12 , a pair ofwires 53 stretched to extend up and down at positions opposite the plurality ofsuction rollers 4, and atension applying means 54 that applies a predetermined tension to the pair ofwires 53. - The
wires 53 in this embodiment are a stainless wire with a diameter of 0.5 mm, and are stretched up and down on the pair ofinner frames 2A at positions opposite the plurality ofsuction rollers 4 disposed on theframes 2A. Thewires 53 are disposed close to both side edges 802 of the printedsheet 8, more specifically, at positions where they press down areas within 3 mm from the side edges 802 of the printedsheet 8. Thewires 53 should preferably press down the printedsheet 8 atpositions 1 to 1.5 mm from the side edges 802. - The
tension applying means 54 in this embodiment is atension spring 54, which is attached respectively to the pair ofwires 53.
As shown inFIG. 10 to FIG. 12 , wire guides 55 are provided at an upper and lower position of theframes 2A for fixing the installation position of thewires 53. One end of thewire 53 is fixed to thewire guide 55 orframe 2A, while the other end of thewire 53 is attached to one end of thetension spring 54, the other end of thetension spring 54 being fixed to theframe 2A.
Tension applied to thewire 53 can be adjusted to a target value by changing the spring constant of thetension spring 54. - The lamination
book binding machine 1 of this embodiment is configured such that, when thesuction rollers 4 feed out a printedsheet 8, thewires 53 under a tension applied by the tension springs 54 press down the printedsheet 8 close to its both side edges 802 against thesuction rollers 4. Further, the laminationbook binding machine 1 of this embodiment is configured such that the thrust-outpress plate 71 deflects the printedsheet 8 when it thrusts the sheet out from between thewires 53 and thesuction rollers 4, as shown inFIG. 12 .
In the laminationbook binding machine 1 of this embodiment, thin copying paper of about 0.1 mm thickness is used as the printedsheets 8 for the book binding. The thickness of the printedsheets 8 can be from 0.08 to 0.12 mm. Paper with a thickness larger than 0.12 mm can also be used as the printedsheets 8 if the paper has a soft texture.
Other elements of the laminationbook binding machine 1 of this embodiment are the same as those of the previously describedEmbodiment 1. - In binding a book using the lamination
book binding machine 1 of this embodiment, half-fold printedsheets 8 are inserted into the gap formed between thedrums 31, the plurality ofsheet feeding rollers 34, theglue application roller 32, and thepressure roller 33 in a way to allow the folded ends 801 to reach the gap first, and glue is applied on oneouter surface 82A of the printedsheets 8 by rotation of thedrums 31, the plurality ofsheet feeding rollers 34, theglue application roller 32, and thepressure roller 33.
The printedsheet 8 with glue applied thereon is fed out to the plurality ofsuction rollers 4, which feed it out onto therail 6. When the printedsheet 8 abuts on therail 6, the feeding force exerted by thesuction rollers 4 acts on the printedsheet 8 and causes it to curl.
To counteract this force, in this embodiment, the pair ofwires 53 with a tension applied by the tension springs 54 press down the printedsheet 8 near its both side edges 802 against thesuction rollers 4. Thus the printedsheet 8 can be prevented from deflecting (losing its flat shape). - Next, the printed
sheet 8 fed out onto therail 6 is thrust out by the thrust-outpress plate 71 to thepredetermined lamination position 702 and bonded to the previously thrust out printedsheet 8. At this time, as shown inFIG. 12 , the thrust-outpress plate 71 deflects the printedsheet 8 as it thrusts the sheet out from between thewires 53 and thesuction rollers 4. The printedsheet 8 can thus be thrust out from between thewires 53 and thesuction rollers 4 without thewires 53 and tension springs 54 being moved specifically for that purpose. Therefore, when the printedsheet 8 thrust out by the thrust-outpress plate 71 is bonded to the previously thrust out printedsheet 8 at thelamination position 702, the printedsheets 8 can be bonded to each other correctly without any wrinkles or the like caused by paper deflection. - Accordingly, with the lamination
book binding machine 1 of this embodiment, half-fold printedsheets 8 can properly be bound into a book without any wrinkles or the like.
Thewires 53 andtension applying means 54 can be applied also to the laminationbook binding machine 1 shown in the above-describedEmbodiment 1.

- The lamination book binding machine according to claim 1, wherein the pair of plate springs are configured to generate an elastic deformation force by elastically deforming in the bent contact portion and a downstream portion in the feeding direction of the base portion, and
a reaction force that acts on the printed sheet when the printed sheet is received by the rail causes tips of the bent contact portions of the pair of plate springs to bite into both side edges of the printed sheet, this biting state being maintained as the thrust-out press plate thrusts out the printed sheet in tight contact with the rail. - A lamination book binding machine for binding a plurality of half-fold printed sheets (hereinafter referred to simply as printed sheets) folded to have printed surfaces facing each other inside into a book by bonding the printed sheets together, the machine comprising:a glue application roller which applies glue to one outer surface of the printed sheet during rotation;a pressure roller which rotates with a constant gap between the pressure roller and the glue application roller so as not to press the printed sheet and feeds out the printed sheet downward together with the glue application roller;a plurality of suction rollers which suck the other outer surface of the printed sheet on which glue has been applied as the suction rollers rotate to feed out the printed sheet onto a rail;a pair of wires stretched up and down at positions opposite the plurality of suction rollers;a tension applying means for applying a predetermined tension to the pair of wires; anda thrust-out press plate which thrusts out the printed sheet fed out onto the rail to a predetermined lamination position to bond the printed sheet to a previously thrust out printed sheet,wherein the wires press down the printed sheet near both side edges thereof against the suction rollers when the suction rollers feed out the printed sheet, so that the thrust-out press plate deflects the printed sheet when thrusting out the printed sheet from between the wires and the suction rollers.
- The lamination book binding machine according to any one of claims 1 to 3, wherein the lamination book binding machine is configured to bind a book with paperboard interposed between the printed sheets, the rail including a receiving position change part capable of receiving paperboard fed out from the plurality of suction rollers at a position higher than an upper surface of the rail, and
the paperboard received on the receiving position change part is thrust out by the thrust-out press plate to be bonded to a previously thrust out printed sheet on the rail at a position separated a predetermined distance from a folded end of the printed sheet.
