[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. 3, the initial setting is performed by engaging the margin portion 12 of the continuous paper P with the pin 19 </ b> B of the paper feed tractor 19 in the cutting and conveying mechanism 13.

  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.

(Cutting process)
Next, as shown in FIG. 3, while the continuous paper P is conveyed in the vertical direction X by the paper feed tractor 19, the continuous paper P is cut into two horizontal rows by the row cutting means 20, and at the same time, the margin portion 12 is cut by the margin cutting means 22. Disconnect. Then, the continuous papers PL, PL in two rows in the horizontal direction are further fed in the transport direction X, and are cut into unit papers PU by the unit paper cutting means 21.

  In this cutting step, the continuous papers PL, PL are cut by the unit paper cutting means 21 while being arranged in two rows in the horizontal direction. Therefore, the single unit paper cutting means 21 can simultaneously cut a plurality of rows. it can. Therefore, simplification and compactness of the apparatus can be achieved. Further, since the posture and arrangement of the continuous papers PL and PL in each row are not changed from the row cutting means 20 to the unit paper cutting means 21, this also simplifies the apparatus and makes it compact. Can be planned.

(Glue application process)
As shown in FIG. 4, the unit paper PU cut by the cutting process is sent to the glue application mechanism 14 in the state of two rows in the horizontal direction. In the glue application mechanism 14, the identification display H of the unit paper PU is read by the reading means. 37. Then, glue is applied to the unit paper PU with the identification display H by the nozzle portion 39 of the glue application means 36, and the unit paper PU without the identification display H is conveyed to the next process without being applied with glue. .

  Two glue applying means 36 are arranged side by side at the same position in the transport direction X corresponding to the unit paper PU in two rows in the horizontal direction, and apply glue under the same conditions at the same time. Similar control can be performed. Therefore, the control of the glue application part can be simplified.

  Further, by providing an 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 stored in advance in the control unit or the like. Even without this, 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.

(Exclusion process)
When the application of the glue to the unit paper PU is completed, an exclusion process is performed before the next superposition conveyance process. In this exclusion process, when the booklet S composed of an odd number of unit sheets PU is produced, the reject plate 42 is swung downward as shown in FIG. 5 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. When performing this exclusion step, the glue application means 36 is controlled so that no glue is applied to the unit paper to be excluded.

(Polymerization transport process)
As shown in FIG. 4, the unit paper PU that has finished the glue application process is sent to the superposition conveying means 45 in the state of two rows in the horizontal direction, and the two unit papers PU arranged in the horizontal direction Y are respectively Overlapping is performed while the posture is changed vertically, and the posture is changed again to the horizontal posture. When the two unit sheets PU, PU are overlaid, they are bonded together with the glue N already applied.

  As shown in FIG. 1, the two unit papers PU are overlapped by twisting the belt conveyors 46 and 47, and thus can be performed in a narrow space in the vertical direction and the horizontal direction Y. Therefore, the apparatus can be made compact.

(Laminated bookbinding process)
As shown in FIG. 7, the unit sheets PU stacked in a set of two sheets are transferred to the transport unit 58 of the stack bookbinding means 61 and further transported to the placement unit 59. In the placement unit 59, the first set of unit sheets PU of two sheets is inserted below the pressing member 84, and then new unit sheets PU are sequentially placed below the unit sheet PU on the placement unit 59. Are inserted 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.
