Definitions
- the present invention relates to a method for realizing an index in one edge of sheets arranged in a stack, for example a telephone directory or the like, comprising the steps that a first number of sheets to be allocated a first index tab is counted off from the stack, that these sheets are provided in their edges with recesses of a first size and/or location, that a second number of sheets to be allocated a second index tab is counted off from the stack, and that these sheets are provided in their edges with recesses of a second size and/or location, and that this procedure is repeated until the intended number of index tabs has been completed.
- the present invention also relates to an apparatus for realizing an index in one edge of sheets arranged in a stack, for example a telephone directory or the like, comprising a holder device for the stack, a punch, cutter or guillotine device for making recesses in the edge of the sheets for forming index tabs, counter means for counting off from the stack such determined numbers of sheets as are to be allocated each index tab and provided with recesses in correspondence therewith.
- the banknotes are counted in that each individual note is grasped by a suction nozzle or suction cup which lifts up a part of the banknote from the stack or wad without breaking the wad.
- the counting of the banknotes is effected in that the number of movement strokes of the suction nozzle or suction cup is registered. If operational reliability is not 100%, substantial errors will be obtained using this technology in the registered quantity if, for example, certain banknotes are leapfrogged such that the suction nozzle moves empty during one or more working cycles. Thus, in such a design and construction, large cumulative errors may occur.
- banknote counting it is also known to break up a wad of banknotes and displace the banknotes with the aid of a transfer mechanism which peels off banknote after banknote from the wad.
- each banknote is registered as displaced from the one stack or wad to the other, for which reason the risk of cumulative errors of the above- outlined type is obviated.
- this technology cannot be applied in respect of flipping or leafing through books which are to be punched so as to form indexes, since the book is already bound or stapled when the index punching is to be carried out.
- banknote counting operation has as its point of departure the counting off from a stack or wad of a certain number of notes or answering the question how many banknotes were there in the wad or stack.
- the present invention has for its object to realize a method of the type mentioned by way of introduction, this method being designed so as to make for reliable and efficient location of those sheets where punching is to be carried out.
- the invention further has for its object to devise a method which offers a very high capacity which can be put into effect fully automatically and with a high degree of precision in the ensuing result.
- the present invention yet further has for its object to design the apparatus intimated by way of introduction in such a manner that this offers a high degree of rapidity, exact precision and great operational reliability.
- the invention yet further has for its object to devise an apparatus which is simple and economical in manufacture and which can operate fully automatically.
- the objects forming the basis of the present invention will be attained in respect of the method, if this is characterized in that at least certain of the sheets are provided with a machine-readable code; that, on the counting-off operation, the sheets are flipped through one or more at a time, the code being read off; and that the flip operation is arrested when the code indicates that the correct sheet has been located through the flip operation.
- the counter means include a machine-readable code on at least certain of the sheets, a reader for sensing the code, a flip device which, on counting of sheets, is operative to flip the sheets one or more at a time, and a control unit which is operative to arrest the flip operation when the reader has registered the correctly flipped sheet and to restart the flip operation when the flipped sheet has been displaced.
- the holder device includes a table for supporting the stack of sheets, there being also provided, along one edge portion of the table, a clamping device for positionally fixing a portion of the stack, and the reader, the flip device and a sheet holder for fixedly retaining against the table portions of sheets in the process of being flipped through being disposed a distance from the clamping device and carried by or together with the table.
- the flip device includes a wheel drivable by drive means, the wheel being urged against those sheets which are to be flipped, the wheel being drivable in one direction in which its point of contact against the sheets moves towards the portion of the stack fixedly retained by the holder device.
- Fig. 1 schematically illustrates an extremely simplified side elevation
- Fig. 2 is a view corresponding to that of Fig. 1 with the stack fixedly clamped in the clamping device;
- Fig. 3 is a view corresponding to those of Figs. 1 and 2 in which the stack has been bent by pivoting of the clamping device;
- Fig. 4 is a view corresponding to those of Figs. 1 - 3, the table and the clamping device having been pivoted to the flip position;
- Fig. 5 is a view corresponding to that of Fig. 4, but on a larger scale;
- Fig. 6 is a vertical side elevation of the subject matter of the present invention seen in a horizontal direction from the punch device; and Fig. 7 is a view seen in the same direction and from the same position as Fig. 6, the table and the clamping device being pivoted to the flip position.
- the present invention entails that a stack of sheets which are bound, stapled or otherwise bonded into book form and which are to be provided with index tabs at one edge opposed to the bound edge along the edge where the index tabs are to be made, are provided with a machine-readable code so that at least certain of the sheets can be identified by reading-off this code.
- the stack is placed in a suitable apparatus and fixedly clamped, whereafter the individual sheets are flipped through in that a rotating wheel or other suitable flip device is pressed against them and flips one or more sheets at a time.
- the wheel is suitably applied against the upper or lower edge portion of the stack (the book) so that the flip operation folds up a corner of each flipped sheet, while the opposing portion of the sheet is retained in abutment against the remaining stack (the book).
- the holder releases its grip, whereafter the retrieved sheet is pivoted to a punching apparatus which punches out a recess in the edge of the retrieved sheet. During this punching operation, the remaining sheets are held in position in the stack under the action of the wheel.
- reference numeral 1 relates to a stack of sheets which are united to form a book or a booklet at one joint region 2. If the stack of sheets is to constitute a bound book with hard covers or cases, the index tabs are punched in the edge 3 before the cases of the book are applied.
- the stack 1 is positioned on a table 4 with the joint edge 2 first in the direction of the arrow 6 so that the joint edge 2 passes through a clamping device 5 which comprises two rollers 7 and 8.
- the rollers 7 and 8 are, on either side of the stack 1 , and also on either side of the table 4 (seen in a direction which is at right angles to the plane of extent of the Drawing in Fig.
- the drive means 10 may be a pneumatic or hydraulic cylinder, a screw mechanism, an electromagnetic prime mover or the like.
- Fig. 2 shows how the stack or book 1 has been passed through the clamping device 5 and clamped in between the two rollers 7 and 8. In such instance, the greater part of the book 1 rests on the table 4 and the joint edge 2 extends past and outside the two rollers 7 and 8.
- the distance from the edge 3 where the index punching is to be made and to the centre of the lower roller 8 is determined partly by the size of the punching and partly by the distance between this roller and the punch device 11 intimated in Fig. 3.
- the punch device 11 includes a lower knife 12 and an upper knife 13, and the lower knife may be considered as fixed while the upper knife is movable in a direction up and down for cooperating with the lower knife.
- both the table 4 and the clamping device have been rotated a further 90° in a counterclockwise direction about the centre axis of the lower roller 8 which is now located at a higher level than the upper roller 7.
- the table 4 is pivotal about the centre axis of the lower roller 8 and that the clamping device, i.e. that unit which is formed by the two rollers 7 and 8, a flip support 16 and the cylinders 10, is also pivotal about this centre axis.
- the pivotal movement of the clamping device is operated by drive means (not shown in Figs. 1 - 4) such as a cylinder which connects the clamping device to the table 4 so that thereby, in each selected position of rotation of the table 4, the clamping device may be rotated in relation to the table.
- the table has, as mentioned above, been pivoted up to a flip position and it will be apparent that both the flip wheel 14 and the sheet holder 15 have accompanied this movement.
- the flip wheel 14 is, with its drive motor and the sheet holder 15, suspended so as to accompany the movements of the table and can thereby be suspended directly in the table or in that carrier member which in turn carries the table proper.
- the flip support 16 extends straight out towards the upper surface of the lower knife, and the upper surface of the flip support lies approximately flush with the upper surface of the lower knife.
- the flip operation proceeds in such a manner that the flip wheel 14 is set in motion in accordance with the arrow (see also Fig. 7) so that the portion of the flip wheel abutting against the book moves in a direction towards the clamping device and towards the flip support 16.
- the outermost sheet in that corner portion of the stack or book 1 against which the flip wheel abuts will be displaced in a downward direction so that it releases its grip with the flip wheel.
- the portion of the sheet most proximal the observer in Fig. 4 is, however, retained against the book with the aid of the sheet holder 15 so that a released sheet is prevented from falling down towards the flip support 16.
- the sheets in the stack 1 are provided with machine- readable codes 17 which are arranged so as to indicate the beginning and possibly also the end of that number of sheets which are to be punched in the punch device 11 in the same manner and which, thereby, are to have the same gripping tab.
- machine- readable codes 17 which are arranged so as to indicate the beginning and possibly also the end of that number of sheets which are to be punched in the punch device 11 in the same manner and which, thereby, are to have the same gripping tab.
- the flip wheel 14 is arrested and the sheet holder 15 is moved aside so that the counted number of sheets is released.
- the upper knife 13 is lowered so that the intended recess is punched into the counted number of sheets. Thereafter, the knife 13 is once again raised and the punched number of sheets forced down beneath the lower knife 12.
- the sheet holder Simultaneously with the punching or after the depression of punched sheets, the sheet holder will once again have been moved to the position shown on the Drawings and the flip wheel 14 once again have been set in motion. In such instance, it is of no consequence whether the flip wheel is driven in such a manner that, at the beginning of or during a flip sequence, it flips through several sheets at a time, as long as the flip operation can be effected with one sheet at a time in the vicinity of those codes which the reader 18 registers.
- Fig. 5 shows, on a larger scale, the clamping device 5, the lower portion of the table 4 and the punch device 11.
- the flip operation of a predetermined number of sheets and the punching thereof have proceeded to such an extent that a number of groups of sheets 19 have been ready- punched and are downwardly folded beneath the lower knife 12 while one group of sheets 20 is located on the lower knife 12 and remaining groups 21 of sheets as yet unflipped from the book 1.
- the group 20 of sheets which is located on the knife 12 is still not yet punched.
- the upper knife has two edges 23 and 24 making an angle with one another, where the edge 24 lies in the plane of the Drawing, while the edge 23 makes a right angle with the plane of the Drawing.
- the lower knife 12 has a cross edge 26 which cooperates with the cross edge 24 of the upper knife 13 and a longitudinal edge 25 which cooperates with the longitudinal edge 23 of the upper knife 13.
- the punching is effected in that the upper knife 13 is lowered with the edges 23 and 24 at least down to a level flush with the edges 25 and 26 but preferably somewhat further. Thereafter, the upper knife is once again raised, whereupon the holder 22 is also returned upwardly to its starting position. Simultaneously with the return stroke of the knife 13 and the holder 22, a plunger 27 may be activated and be forced in a downward direction so that the punched group 20 of sheets is moved down on the upper side of the downwardly bent groups 19 below the lower knife 12. Before the next punching operation is carried out, relative displacement also takes place along the longitudinal direction of the rollers 7 and 8 between the punch device 11 and the clamping device 5 with the table 4.
- the edges of the punchings will be at right angles to the front and rear faces of the book. If, instead, a punching is desired which is obliquely inclined in the same manner as the edge 3 slopes in relation to the major portion of the plane of extent of the book 1 in Fig. 3, the clamping device 7, 8 in Fig. 4 is turned slightly in a counterclockwise direction so that the flip support points slightly obliquely upwards. This will have as a consequence that the group of sheets 20 which is to be punched will be bent, for which reason the edges 3 of the individual sheets will be offset in relation to one another in the punching position. When, in this position, the punching is made straight, the punched incision surface will, after return twisting of the group to the flat state, be oblique in relation to the plane of extent of the sheets.
- Fig. 6 shows the subject matter of the present invention seen from the punch device 11 , i.e. from the left in Figs. 1 - 5, in which event the table 4 and the rollers 7 and 8 are located in the starting position according to Fig. 1.
- the apparatus includes a frame portion 28 which is displaceably disposed in accordance with the double-headed arrow 29 in a frame (now shown on the Drawings) for the machine.
- This displacement according to the arrow 29 is carried out between punching of each group of sheets so that, thereby, the punched recesses will obtain the correct position in the longitudinal direction of the edge 3 of the book.
- This displacement according to the arrow 29 constitutes an alternative to the above-mentioned relative displacement between the table 4 (shown by broken lines behind the roller 8) and the punch device 11.
- the frame portion 28 has upwardly directed shanks 30 with guides 31 in which carriers 32 are vertically adjustably accommodated, the carriers having journals 33 for pivotally supporting the roller 8. For revolving the roller 8, this is provided with a transmission 34 which connects it to a drive motor 35 which is carried by the carrier 32 or is movable together therewith.
- the table 4 is pivotal about the centre axis of the roller 8 and is carried by the roller via journals 36 and carrier arms 37. Furthermore, the roller 8 is interconnected with the table 4 for mutual rotation via a linkage 38 and a prime mover (not shown), for example a pneumatic or hydraulic cylinder or the like, which is placed on the underside of the table 4 and is secured in the table.
- a reader 18 reads off the code 17 on a sheet 1 which is fixedly clamped on the table 4.
- This reader is adjustable in relation to the table but is also arranged in such a manner that it accompanies the table in its pivotal movements.
- the reader 18 may be movable along an arm 39 which is secured in the journal 36 or possibly direct in the table.
- Fig. 7 shows the table raised to the flip position (Cf. Figs. 4 and 5), i.e. pivoted 90° in relation to the position according to Fig. 6.
- the flip wheel 14 has a drive motor 40 which is secured in a suspension 41 which may be disposed directly on the table 4 or on some other component which is pivotal together with the table.
- the suspension is such that the flip wheel 14 can be lifted away a distance from the table 4 on insertion of a book (as intimated in Fig. 1), whereupon the flip wheel can be applied against the book with suitable and adjustable pressure.
- the adjustment possibilities of the suspension 41 also include the possibilities of catering for books of different thicknesses.
- the sheet holder 15 is, as was intimated above, disposed in such a manner that it accompanies the table 4 in its pivotal movements. To this end, the sheet holder may be disposed and secured directly on the table but may also be placed on some other component which accompanies the table in its movements. Furthermore, the sheet holder 15 is removable so that it does not prevent insertion of a book (according to Fig. 1) and further, it is coupled to drive means (not shown on the Drawings), permitting disengagement from the engagement position with the book when a counted number of sheets is to be released folded down for punching.
- the flip device comprises a flip wheel which, by friction against the sheets, flips through them.
- a device with suction nozzles which grip sheet after sheet and thereby flip through the sheets.
- One such a device may be rotary, with a plurality of nozzles, but may also operate with a single nozzle in a reciprocating movement.
