14 is an adhesive storage tank, 15 is a pipe, 16 is a packing, 17 is a packing spring, 18 is a connector, and 19 is a packing spring holder.

FIG. 3 is a detailed view showing the pedestal and the vicinity of the connector. 1st
This will be further explained with reference to the figures. The upper part of the bound document 12 constitutes a punch unit, and the lower part constitutes a gui unit. The guide post 5 guides and holds the punch unit and the gouging unit.

When the bound document IW12 that has been copied or printed is aligned on the guide 6, the upper punch unit descends and the stripper 11 presses the paper and comes to rest, the punch 1 further descends against the spring 10 in this state. , bound documents! 2 and reaches the packing 16, further descends against the packing spring 17, hits the pedestal 7, and descends again against the pedestal spring 8, reaching the dead point of the drive cam (not shown). Convert to upward drive. During this drive, the packing 16 descends into close contact with the inner wall of the pedestal 7, and the adhesive 13 is transferred from the adhesive storage tank 14 via the vibrator 15 to the connector 18 to the pedestal 7 through the hole 7a on the side surface of the pedestal 7.
7 by the siphon effect. The timing at which the adhesive 13 is injected at this time can be adjusted by moving the retaining ring 3 directly below the punch guide plate 4 to a position such as 3' or 3'', and moving the adhesive storage tank 14 up and down. The injection amount can be adjusted.

FIG. 4, FIG. 5, and FIG. 6 are explanatory diagrams illustrating the movement of the adhesive when the punch unit starts to rise. When the punch 1 lowers the packing 16 with its sharp tip against the packing spring 17, the adhesive 13 enters the holder 7 (Fig. 4).As the punch moves upward, the adhesive 13 is applied to the bound documents. When the punch 1 leaves the upper part of the pedestal 7, the burr begins to penetrate into the burr created by the hole 12 (FIG. 5). Immediately after that, the stripper 11 is lowered by the action of the spring 1o, and the bound document 12 is removed by the stripper 11.
When the punch 1 is further raised, the adhesive 13 closes the hole, and the detailed marking M12 is pressed and joined by the packing 16 (Fig. 6), completing the furrowing work. .

To further explain the above example, prepare a plurality of sheets of paper that have been copied, punch a hole with a sharp-tipped punch 1, make the hole of the gouge 6 larger, and perform the burring process in the same way as the burring process during press processing. Immediately after the punch 1 penetrates, the adhesive 13 is applied to the siphon by moving the adhesive 13 up and down the tank 14 through a flexible vibrator 15 made of plastic (polyethylene, nylon, etc.) from a tank 14 containing adhesive that can be raised and lowered. The effect makes it possible to adjust the pressure at which the adhesive flows out, and by stopping the gap between the punch 1 and the die 6 and changing the position of the pump 3 to the position 3' or 3'', the timing and amount of the adhesive jetted out can be adjusted. the die 6 and the packing 16 at the same time as the punch l rises.
The packing 16 also rises and pushes up the burr part of the binding type 1 12 so that it comes into pressure contact with the stripper 11. The packing 16 also rises and pushes up the burr, and at the same time as the pressure welding is completed, the adhesive 13 is brought into contact with the packing 16. It is sealed and shut off by the slope of the stand 7. Then, when the punch l further rises, the stripper 11 is lowered by the spring 10, and the bound document 1
2 is crimped.

In the above embodiment, the adhesive 13 contained in the adhesive storage tank 14 is in the form of a slime, and is injected according to the number of sheets of the bound document 12 by positioning the tank 14 upward or downward. (Gushing) Pressure can be adjusted.

The distance between the punch 1 and the die 6 is determined by using a movable retaining ring 3.
The timing at which the adhesive 13 is sprayed onto the bound documents 12 can be adjusted.

The packing 16 is configured as a resilient side, and the timing at which the adhesive 13 is ejected can be adjusted by checking the interlocking timing between the punch 1 and the die 6.
