Further, as shown in FIG.
Controls the driving mechanism 26 of the pressing roller 15 and the motor 27 for the driving roller 18 based on the detection of the leading end or the trailing end of the printing paper of the photo interrupter 24, respectively.

The operation of the bookbinding apparatus 1 described above will be described with reference to FIG. First, the printing paper is sequentially conveyed from a copying machine or the like in the direction F by the conveying roller pair 13 or the like, and the leading end of the printing paper P2 is positioned between the light emitting element 24a and the light receiving element 24b of the photo interrupter 24 as shown in FIG. When it reaches, the light from the light emitting element 24a is cut off, and the leading edge detection signal is sent to the control device 25 of FIG.
Is detected (S01).

When the control device 25 receives the leading end detection signal, it activates the pressing roller driving mechanism 26 after a predetermined time has elapsed, and moves the pressing roller 15 in the direction V as shown in FIGS. 2 and 5A. By this operation, the printing paper P of FIG.
Is sandwiched between the pressing roller 15 and the fixed roller 14 at the side end PA of the adhesive tape 21 and the leading end PT of the printing paper P. In this manner, the adhesive tape 21 is brought into contact with the printing paper P near the leading end 22a of the adhesive layer 22 and pressed, whereby the leading end 22a of the adhesive layer 22 is attached to the leading end PT of the printing paper P. Stick. This pressing roller 15
At the same time, the control unit 25 drives the motor 27 (S02). Thereby, the take-up reel 17 rotates in the rotation direction Q in FIG. 2, and the adhesive tape 21 starts to move together with the printing paper P.

On the other hand, the release tape 23 of the adhesive tape 21
Is wound on the take-up reel 17 and moves in the direction t as shown in FIGS. 2 and 5A, so that the adhesive layer 22
As shown in FIG. 5B, the printing paper P is peeled off from the peeling tape 23, adheres to the printing paper P from the leading end PT in FIG. 5A, and moves in the direction F together with the printing paper P. Since the peeling tape 23 is wound on the take-up reel 17, the take-up reel 16 rotates in the rotation direction R in FIG. 2, and the adhesive tape 21 is sent out from the take-up reel 16 to the pressing roller 15. In this way, the adhesive layer 22 is attached to the lower surface of the printing paper P by the side edge PA.
(S0)
3). In this case, since the printing paper P and the adhesive tape 21 move at the same speed in the same direction F, the adhesive layer 22 is stuck to the printing paper P without hindering the mutual operation, and one end of the printing paper P The application from to the other end is easily performed.

Next, when the trailing edge of the printing paper reaches between the light emitting element 24a and the light receiving element 24b, the light from the light emitting element 24a enters the light receiving element 24b, and the trailing edge detection signal is applied to the control device shown in FIG. 25, and detects the rear end of the printing paper P2 (S04). When receiving the trailing edge detection signal, the control device 25 drives the pressing roller driving mechanism 26 after a lapse of a predetermined time, moves the pressing roller 15 in the direction V ′, and presses the adhesive tape 21 against the printing paper. To release. At the same time, the drive of the motor 27 is stopped, the rotation of the take-up reel 17 is stopped, and the movement of the adhesive tape 21 is stopped. Since the printing paper moves in the direction F and the adhesive tape 21 does not move, the adhesive layer 22 is pulled and broken near the rear end of the printing paper. Thus, the application of the adhesive layer 22 to the printing paper P is completed (S06). In this manner, the adhesive layer 22 can be applied from one end to the other end along the side edge PA of the printing paper P. Steps S01 to S06 are repeated for a predetermined plurality of printing papers (S07).

The predetermined time in steps S02 and S05 is set based on the moving speed of the printing paper and the distance from the leading (rear) detecting position to the pressing position of the pressing roller 15 and the fixed roller 14. Can be.

When a predetermined number of printing papers P to which the adhesive layer 22 has been applied are placed on the inclined loading plate 31 of the paper storage unit 30, a pair of alignment plates 32a and 32 are provided as shown in FIG.
b is moved in the direction S from the position indicated by the solid line to the position indicated by the alternate long and two short dashes line by a driving device (not shown) to align the plurality of printing papers P in the direction S. Next, the upper surface side of the printing paper is pressed by the pressing means along the side edge PA in the direction W of FIG. 2 to ensure the adhesion of the printing paper by the adhesive layer. This pressurization is performed, for example, every 2 to 5 sheets, and when all pages have been completed, the printing paper P on which all pages are adhered by the adhesive layer 22 is moved by, for example, a moving mechanism that moves the wall portion 32 in the direction X in FIG. From the paper storage unit 30. Thus, one bookbinding is completed. Further, the above steps can be repeated to perform bookbinding a plurality of times.

As described above, according to the adhesive application apparatus of the bookbinding apparatus of the present embodiment, the adhesive tape is sent out, the adhesive layer is brought into contact with the printing paper while the peeling tape is wound up, and the pressure is applied. Since it is a configuration in which the adhesive layer is applied by releasing, a compressor or a pump, a tank, a nozzle equipped with an electromagnetic valve, a conduit connecting these, and the like as in the conventional device are unnecessary, and Since the adhesive has no fluidity, there is no need for a reversing mechanism for reversing the front and back of the sheet, and further, there is no need to take measures against nozzle clogging. For this reason, the device configuration can be greatly simplified as compared with the conventional device, the cost can be reduced, and the maintenance and management thereof can be extremely simplified.

As described above, the present invention has been described based on the embodiments. However, the present invention is not limited to these embodiments.
Various modifications are possible within the scope of the technical idea of the present invention. For example, although the transmission type photo interrupter is used as the detection means of the front end (rear end) of the printing paper, the reflection type may be used. Also, instead of the leading edge (rear edge) of printing paper,
Another portion of the printing paper may be detected, and the leading end (rear end) position may be detected from the detected position. Further, both the take-up reel and the take-up reel may be driven, or the pressing roller may be driven to rotate. In addition, the sheet material to which the adhesive layer is applied may be a sheet material other than paper, or may be a transparent film sheet or the like.
