Then, the continuous paper PL in each row is superposed in the vertical direction using the paper feed tractor 26 of the row superposition conveyance means 23 and conveyed in the vertical direction X (row superposition conveyance step). The upper and lower continuous sheets PL, PL are sent to the row cutting means 21 and cut into unit sheets PU (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 paper PL into unit papers. Therefore, simplification and compactness of the apparatus can be achieved.

(Glue application process)
As shown in FIG. 4, the unit papers PU and PU stacked one above the other are separated up and down by the separation guide member 52 of the unit paper separation means 50, and further, as shown in FIG. It is adsorbed by the belt conveyors 51A and 51B and conveyed by two paths up and down.

  By separating the unit papers PU and PU thus superposed, it is possible to superimpose and simultaneously cut two rows of continuous papers PL and PL in the previous unit paper cutting step, while applying the subsequent glue coating. In the cloth process, glue can be applied to each of the unit sheets PU stacked one above the other.

  Further, since the margin portion 12 is used to separate the unit papers PU, PU stacked one above the other, the separation work can be performed easily and reliably.

  As shown in FIG. 1, the unit papers PU and PU conveyed in multiple rows by the upper and lower belt conveyors 51A and 51B are transferred to the belt conveyors 38 and 38 as they are, and as shown in FIG. Display H is read by reading means 37. Then, the unit paper PU with the identification display H is applied with glue by the nozzle portion 39 of the glue application means 36, and the unit paper PU without the identification display H is conveyed as it is without being applied with the glue.

  The glue applying means 36 in each row are provided at the same position in the transport direction X, and apply glue under the same conditions at the same time. Therefore, the same control can be performed for both glue applying means 36, and the control of the glue applying means 36 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. 6 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.

(Unit paper superposition process)
As shown in FIG. 1, the unit sheets PU and PU in each row after the glue application process are sent to the unit sheet superimposing and conveying means 45 and conveyed by two upper and lower belt conveyors 46 and 47. At the end of conveyance of the belt conveyors 46 and 47, the unit sheets PU corresponding to the upper and lower sides are simultaneously delivered to the placement unit 58 of the stack bookbinding means 61 and are superimposed on the placement unit 58. The two unit papers PU that are overlaid are bonded together by glue N applied between them.

  As shown in FIG. 1, the two unit papers PU are overlapped by arranging the end of each belt conveyor 46, 47 in the same direction. It can be simplified.

(Laminated bookbinding process)
As shown in FIG. 7, the unit sheets PU superimposed on one set of two sheets are conveyed to the placement unit 59 by the conveyance unit 58 of the stack bookbinding means 61. 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.
