JP-A-9-31530 Japanese Patent No. 3606734

  In the conventional bookbinding apparatus 101, after the continuous paper P is cut into two horizontal rows by the center slitter 106, the continuous paper PL in each row is superposed on each other by the glue application cutting unit 103, and the processing up to the bookbinding is superposed thereafter. I'm going. Accordingly, it is necessary to apply glue in advance between the continuous sheets PL, PL in each row before superimposing.

  On the other hand, in the conventional bookbinding apparatus 101, in order to initially set the continuous paper P when starting the bookbinding operation, the continuous paper PL cut into two horizontal rows from the supply device 102 is fed to the paper feeding tractor 111 of the glue application cutting unit 103. It is necessary to manually pull out until the paper feed tractor 111 is overlaid with two rows of continuous paper PL.

  At this time, since the glue cannot be applied to the lower continuous paper PL using the glue application unit 110A between the paper feed tractor 111 and the glue application unit 110A, it is difficult to apply the glue to the continuous paper PL during this period. Must be done by work. Such a manual application of glue is a very complicated operation and requires time and effort. In addition, in order to eliminate the application of glue manually, the continuous paper between the paper feed tractor 111 after the initial setting and the glue application unit 110A may be handled as waste paper (spreading paper), but this wastes resources. It is not preferable.

  In addition, manual continuous paper setting is necessary not only when bookbinding starts but also when paper jams during bookbinding. If the glue is applied manually during the resetting of the continuous paper, the bookbinding operation must be interrupted for a long time. Further, since the paper in the middle of bookbinding cannot be handled as waste paper, it is not possible to omit application of glue by hand.

  Further, the conventional bookbinding apparatus 101 requires two glue application portions 110A and 110B, and the glue application portions 110A and 110B are separated from each other in the transport direction X, so that different control is performed for each. There is also a disadvantage that the control becomes complicated.

  In addition, margin portions in which a large number of paper feed holes are formed in one row are provided on both sides in the horizontal direction of the continuous paper. In the conventional apparatus shown in FIG. 12, continuous paper is cut into a plurality of horizontal rows by the center slitter 106. In addition, the margin portion is cut by the margin slitter 115 after the paste is applied by the paste applying portion 110A. At this time, if the margin part is cut in a state where the continuous sheets in each row are aligned in the horizontal direction, there is a possibility that not only the margin part of one unit sheet but also the end part of the other unit sheet will be cut. Therefore, in practice, the upper and lower unit sheets are superposed with a slight shift to the respective margin portions (see, for example, FIG. 4).

  However, if the continuous sheets are shifted in the horizontal direction and overlapped, the pages of the booklet after bookbinding are also uneven in the horizontal direction, which causes a decrease in bookbinding quality. When cutting the margin part, since the upper and lower continuous sheets are already bonded with glue, the lateral displacement cannot be corrected.

The present invention has been made in view of such circumstances, it is possible to perform an initial set or re-set the continuous paper easily, also provides a manufacturing This equipment capable of simplifying the control of the adhesive coating operation The purpose is to do.

The restriction plate 79 is formed at a relatively low height so as to correspond to the lower part of the unit paper PU stacked on the placement unit 59. The rear restricting portion 77 includes a rear restricting guide 80 with which the rear end portion in the transport direction X of the unit paper PU can abut. The rear regulation guide 80 is a bar that is long in the vertical direction, and is formed to have a length corresponding to the maximum stacking amount of the unit paper PU with respect to the placement unit 59.

  The horizontal regulating portion 78 is disposed corresponding to the lower portion of the unit paper PU stacked on the upper surface 59A of the placement portion 59, and is provided with a guide roller 81 that abuts both ends in the lateral direction Y of the unit paper PU, and the unit paper. The guide rod 82 is in contact with both ends of the lateral direction Y of the PU. The guide roller 81 is provided coaxially with the intermediate roller 67 of the lower belt conveyor 64 and rotates together with these rollers 67. The guide rod 82 is formed to have a length corresponding to the maximum amount of unit paper PU stacked on the placement unit 59.

  The placement unit 59 is provided with a pressing member 84 that presses the unit paper PU on the placement unit 59 from above. The pressing member 84 is formed of a plate material that is substantially the same size as the unit paper PU. In this embodiment, it is transparently formed by resin materials, such as an acryl, and the state under the holding member 84 can be visually recognized now. A gate-shaped handle 85 is provided on the upper surface of the pressing member 84.

  As shown in FIG. 1, the glue application mechanism 14 and the stack bookbinding mechanism 17 are provided in the fourth device frame 5 that can be moved by the portable wheels 5 </ b> A. The first to fourth device casings 2, 3, 4, and 5 are configured to be connectable and separable.

[Operation process of bookbinding device]
Hereinafter, the operation process of the bookbinding apparatus 10 will be described together with the effects.
(Initial setting of continuous paper)
First, the initial setting of the continuous paper P with respect to the bookbinding apparatus 10 is performed. As shown in FIG. 1, this initial setting is performed by engaging the margin portion 12 of the continuous paper P with the pin 19B of the paper feed tractor 19 in the cutting and transporting mechanism 13, or the continuous paper P in the horizontal direction 2 After cutting into rows, the continuous paper PL in each row is engaged with the pins 26B of the paper feed tractor 26.

  Therefore, since the initial setting of the continuous paper P to the stage where the glue application process is not performed is possible, it is not necessary to manually apply the glue at the time of the initial setting as in the prior art. Therefore, the initial set operation can be performed easily and quickly. In addition, it is economical because it does not generate waste paper.

(Cutting process)
As shown in FIG. 3, the continuous paper P is cut into two horizontal rows by the row cutting means 20 while being conveyed in the vertical direction X by the paper feed tractor 19 (row cutting step). Then, the continuous paper PL in each row is superposed vertically using the paper feed tractor 26 of the row superposition conveyance means 23 and is conveyed in the vertical direction X (row superposition conveyance step). The upper and lower continuous sheets PL, PL are cut into unit sheets PU by the row cutting unit 21 after the margin unit 12 is cut by the margin unit cutting unit 22 (unit sheet cutting step).

  In this cutting step, two rows of continuous papers PL, PL are stacked one above the other, so that one unit paper cutting means 21 can simultaneously cut two rows of continuous papers PL, PL into unit papers PU. Therefore, simplification and compactness of the apparatus can be achieved.

(Separation transport process)
As shown in FIG. 6, the unit papers PU and PU sent in a two-ply manner through the cutting process are transported at an increased speed by the lower transport body 48, and are thereafter sandwiched between the upper and lower transport bodies 47 and 48. The unit papers PU and PU are separated in the vertical direction X one by one due to the difference in transport speed between the upper and lower transport bodies 47 and 48.

  As a result, in the subsequent glue application process, the glue application work can be performed using one glue application means 36. Therefore, the structure of the glue application mechanism 14 can be simplified and the control of the glue application means 36 can be simplified.

  In addition, since the unit sheet PU, PU of two sheets is separated one by one using the difference in transport speed between the upper and lower transport bodies 47, 48, the speed of the upper and lower transport bodies 47, 48 is controlled for separation. Just do it. Therefore, it is not necessary to provide a complicated structure, and the structure can be simplified. Further, as shown in FIG. 7, since the belt conveyors 49 and 50 of the upper and lower transport bodies 47 and 48 are arranged so as to overlap vertically (W), the upper and lower unit papers PU are placed on the upper and lower transport bodies 47 and 48, respectively. The unit paper PU can be transported at an accurate transport speed and reliably separated in the vertical direction X. Further, even when handling unit sheets PU having different thicknesses, it is not necessary to adjust the vertical positions of the upper and lower belt conveyors 49 and 50 each time.

  As shown in FIG. 6, the unit sheets PU separated one by one are fed to the horizontal alignment conveyance unit 46 by being accelerated or decelerated by the synchronous conveyance roller 52. As a result, the unit paper PU can be conveyed to the horizontal alignment conveying means 46 at regular intervals.

  As shown in FIG. 8, in the horizontal alignment conveyance unit 46, the unit paper PU is aligned in the horizontal direction when one end in the horizontal direction abuts against the regulating member 55. Therefore, as shown in FIG. 4, even when the continuous paper PL is shifted in the horizontal direction and overlapped for cutting the margin portion 12, the horizontal deviation can be corrected before applying the glue, and thereafter , Bookbinding quality can be improved.

(Exclusion process)
When the separation and conveyance process is completed, an exclusion process is performed before reaching the glue application process. In this exclusion step, when the booklet S composed of an odd number of unit papers PU is produced, the reject plate 42 is swung downward as shown in FIG. 9 to correspond to the last page of the booklet S. The unit paper PU is excluded. Therefore, in the bookbinding apparatus 10 of this embodiment, a booklet can be produced regardless of an even number or an odd number, and versatility can be improved.

(Glue application process)
As shown in FIG. 1, in the glue application process, the unit paper PU is conveyed one by one by the upper and lower belt conveyors 38, 38, and the identification display H of the unit paper PU is read by the reading unit 37 as shown in FIG. 10. It is done. Then, the unit paper PU with the identification display H is applied with the glue by the nozzle portion 39 of the adhesive application means 36, and the unit paper PU without the identification display H is conveyed to the next process as it is without being applied with the adhesive.

  By providing the identification display H on a predetermined unit paper PU and controlling the glue applying means 36 based on the detection of the identification display H, the number information of the booklet S is not stored in the control unit or the like in advance. Also, the glue applying means 36 can be accurately controlled. Further, even when the number of booklets S changes in the middle, the paste can be appropriately applied to the predetermined unit paper PU.

  The paste application period for one unit paper PU is controlled based on detection by the two paper detection sensors 40. That is, when the unit paper PU is detected by both the paper detection sensors 40, the glue is discharged from the nozzle unit 39, and when the unit paper PU is not detected on the one hand, the application of the glue is stopped. As a result, even when the length of the unit paper PU in the vertical direction X changes, there is no need to adjust the glue application period, and the glue according to the length of the unit paper PU in the vertical direction X is always maintained. Application can be performed.

(Laminated bookbinding process)
As shown in FIG. 11, the unit sheets PU sent one by one from the glue application mechanism 14 are conveyed to the placement unit 59 by the conveyance unit 58 of the stack bookbinding unit 61. In the placement unit 59, the first sheet of unit paper PU is inserted below the pressing member 84, and then new unit papers PU are sequentially inserted below the unit paper PU on the placement unit 59. And stacked. By this lamination, the unit paper PU is bonded with the glue applied to the predetermined unit paper PU, and the booklet S is produced.

  In this way, by sequentially stacking the unit sheets PU from the lower side, the adhesion can be promoted by the weight of the unit sheets PU already stacked. Further, by providing the pressing member 84, adhesion of the unit paper PU can be further promoted.

  In order to take out the produced booklet S from the placing portion 59, the pressing member 84 is removed, and the booklet S is taken out backward in order from the uppermost booklet S. Therefore, the booklet S can be taken out even during the bookbinding operation. Further, it can be taken out as a booklet S in the order of printing on the continuous paper P.

[Other Embodiments]
The present invention is not limited to the above-described embodiment. For example, the design can be changed as follows.
(1) The unit sheet discharge speed V2 of the unit sheet cutting means 21, the upper and lower transport bodies 47 and 48 of the unit sheet separating and transporting means 45, the transporting speed V1, V3 and V4 of the synchronous transport roller 52 are as follows: Although the specific numerical value is shown in the said embodiment, it is not limited to this, It can change suitably.

(2) Further, the difference in transport speed between the upper and lower transport bodies 47 and 48 of the unit sheet separation transport means 45 can be configured to be adjustable. As a result, the unit paper PU can be appropriately separated and transported according to the length X of the unit paper PU, the material, and the like.
In this case, the conveyance speed difference between the upper and lower conveyance bodies 47 and 48 can be adjusted to zero (constant speed). As a result, when bookbinding is performed using continuous paper P in one row in the horizontal direction, the separating and conveying means 45 can be used for conveying one unit paper PU that is not superimposed.

(3) In the above embodiment, the number of the belt conveyors 50 of the lower transport body 48 is smaller than that of the belt conveyor 49 of the upper transport body 47, but the reverse is also possible.

(4) In the above embodiment, in the stack bookbinding mechanism 17, the unit sheets PU are sequentially stacked below, but may be stacked sequentially. Further, the stacking direction of the unit sheets PU is not limited to the vertical direction, and can be the front-rear direction or the horizontal direction (left-right direction).

(5) In the above embodiment, the identification display H is provided on the unit paper PU to which glue is applied. However, even if the identification display H is provided on the unit paper PU to which no glue is applied, that is, the first unit paper PU of the booklet S. Good.

(6) In the above embodiment, the identification display H is provided on the unit paper PU to which glue is applied. However, the identification display H is omitted, and the information on the number of booklets S is stored in the control unit of the bookbinding apparatus 10 in advance. The paste may be applied based on the number information.

(7) The exclusion step can also be performed between the paste application step and the stack bookbinding step. In this case, the glue applying means 36 may be controlled so that glue is not applied to the unit paper to be excluded.

(8) In the above embodiment, when the booklet S composed of an odd number of unit sheets PU is produced, the unnecessary unit sheet removing means 43 is operated to eliminate unnecessary unit sheets PU. It can also be configured as follows. For example, in the continuous paper P shown in FIG. 2, when it is assumed that one booklet S is produced with three unit papers PU, the first book is printed on the unit papers PU of (1) to (3), Subsequently, the second print is performed on the unit paper PU of (4) to (6). That is, it prints continuously without making a blank unit sheet. Then, the continuous paper P is cut for each unit paper PU by the cutting and transporting mechanism 13, and the unit paper PU is separated one by one by the separation and transporting mechanism 16 so as to be in the order of (1) to (6). The glue is applied to the unit paper PU other than (1) and (4) by the glue application mechanism 14, and the unit paper PU is stacked one by one by the lamination bookbinding mechanism 17 and bound. By doing so, it is possible to easily produce an odd number of booklets S regardless of the number of rows of continuous paper P, and wasteful unit paper is not generated, which is efficient in terms of resource saving and economical efficiency. A bookbinding apparatus can be configured.

  The present invention can be effectively used as, for example, a bookbinding device for producing a bound slip such as a tax payment notice.
