As shown in FIGS. 1 and 6, after setting in the box 1, the workpiece 6 is placed on the tilting plate 4 with the press plate 3 raised, and the door 2 is closed and the switch is turned on. By inputting, the press plate 3 descends. Since the door 2 is closed during such compression, the buffer roller 29 is in contact with the door 2. For this reason, the press plate 3 descends smoothly without the interlocking shaft 25 engaging with the cylinder 21.

After the object is compressed, the door 2 is opened to release the contact between the buffer roller 29 and the door 2, and the interlocking shaft 25 is urged in the direction of engagement with the cylinder 21. Then, when the press plate 3 is lifted in this state, when the interlocking hook 26 of the interlocking shaft 25 and the engaging hole 23 of the cylindrical body 21 coincide with each other, they are engaged. Thereby, the tilting mechanism 20 operates,
As shown in FIG. 3, the rear side of the tilting plate 4 is lifted and tilted. Therefore, the workpiece 6 can be easily taken out.

Next, the end 9a of the guide bar 9 on the press plate 3 is rotated. This rotation causes the other end 9b of the guide bar 9 to rotate integrally, so that the string 10 hooked on the end 9b is released from the hooked state. With this release, the string 10 falls onto the workpiece 6. Next, if the string 10 is cut to an appropriate length, the string 10
Hanging in front of the Thus, the object 6 is bound by tying the string 10 to the tip tied to the hook fitting 15. Therefore, in such a structure, the string 10
Hangs down to the front side of the processing object 6, so that the complicated operation of pulling out the string 10 at hand becomes unnecessary.

The present invention is not limited to the above embodiment, but can be variously modified.
As long as it guides 0 in the front-rear direction of the workpiece 6, the shape and structure may be different from those shown in the figure.

[0018]

[Effects of the Invention] As described above, the present invention draws a string into the box and guides the string from the front side to the rear side via the guide bar and the connecting plate. Through the lower surface of the object to be processed, it is pulled out to the front side and is connected to the front metal fitting of the box. Then, in order to bind the processing object, first, the string is released from the bent portion at the rear end by rotating the guide bar, and falls on the processing object. Next, if the string is cut to an appropriate length at the vertical portion in the box, the string automatically hangs down to the front side of the object to be processed, and the hanging portion is connected to the end of the string in front of the box. The processed materials can be bound, and the binding operation can be performed extremely easily and in a short time. Further, since the rear side of the tilting plate can be lifted and tilted with the rise of the press plate, the object to be processed can be easily taken out, eliminating the need for a troublesome work process as in the past, and This has the advantage that a dedicated operation member is not required.
