Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper punching device for punching a paper material into a predetermined shape for making a paper box (decorative box) for packing, for example.

[0002]

2. Description of the Related Art Paper boxes (decorative boxes) used for packing various products are printed with necessary characters, figures, etc. on paper, as shown in FIG. 3, and leave perforations and connecting portions a on the paper. The product portion B is taken out from the paper material D in which the notch A is made and the product portion B is assembled in a box shape.

Conventionally, the work of taking out the product portion B from the paper material D may be manually carried out one by one, but it is usually carried out by using a paper punching device as shown in FIG.

The above-mentioned paper punching device is a plate material J shown in FIG.
A metal mold M is attached to a lifting body G of a press machine equipped with an electromagnet P, and a male mold E is formed on the inside of the gap K having a shape similar to that of the cut A of the paper material D. The female mold F, which remains after the male mold E is pulled out, is mounted on the fixed base H below the lifting body G, and the paper material D is placed on the female mold F for 2, 30 After stacking and setting the sheets, when an operation switch (not shown) is turned on and the lifting body G of the press is lowered, the male mold E pushes the product portion B of the paper material D and fits into the female mold F. Then, the product portion B is punched out from the opening Q of the female mold F. It should be noted that the paper scraps after punching out the product portion B remaining on the female mold F are manually removed.

[0005]

However, the above paper punching device has the following problems. ． Since the paper scraps are set after the paper material D is set and the product portion B is punched out between the male mold E and the female mold F, there is no space in the working space and the work is difficult. ． While setting the paper material D and removing the paper scraps after punching the product part B, the lifting body G of the press machine is mistakenly used.
If the operator operates, there is a risk that a person who is working is caught between the molds E and F and injured, which is very dangerous.

An object of the present invention is to provide a paper punching device which is safe and easy to set paper materials.

[0020]

[Description of Operation of Paper Punching Device of FIG. 1] The paper cutting device of FIG. 1 operates in the order described below. ． A desired number of paper materials 5 are stacked and placed on the set slider 12 of FIG. At this time, the edges of the paper material 5 are pressed against the positioning stopper 29 and the movement restricting body 13 to align the stacked paper materials 5. ． When an operation switch (not shown) is turned on, the set slider 12 moves in the direction of arrow a in FIGS. 1 (a) and 1 (b), and the paper material 5 set on the set slider 12 waits downward. Can be replaced on top. ． When an operation switch (not shown) is turned on again, the hydraulic cylinder 27 operates to raise the guide rail 26 (away from the belt conveyor 11), and then the slider 2
5 moves in the direction b in the figure, and the female die 6 and the paper material 5 move below the male die 7. ． When the female die 6 and the paper material 5 are set under the male die 7,
The hydraulic cylinder 27 operates to lower the guide rail 26, and then the hydraulic cylinder 24 for pressing operates to lower the pressurizing body 10, and at the same time, the male die 7 is placed under the paper material 5.
The product part 3 is crushed and fitted into the female mold 6. ． After the male mold 7 and the female mold 6 are fitted together, the male mold 7 moves up and returns to its original position. Then, when the hydraulic cylinder 27 operates, the guide rail 26 moves up again, and then the belt conveyor 11 operates. The punched product part 3 is sent out of the apparatus. ． Next, the slider 25 moves in the direction of arrow c and stops at the middle position of the guide rail 26. Here, the worker waiting on the side of the guide rail 26 takes out and discards the unnecessary portion 4 remaining on the female mold 6. ． When the operation switch (not shown) is turned on again, the slider 25 moves in the direction of arrow c, and the set slider 12
Return to the bottom of. ． After that, the above-mentioned operations are repeated.

[0021]

According to the paper punching device of the present invention, the paper material 5
Since the scraps generated after the setting and the pressing can be taken out of the male mold 7, the work safety is high, and the paper material 5 can be easily and quickly set in the female mold 6.
