Description

[Detailed description of the invention] The present invention relates to a method of manufacturing a cutting die device for paper processing.

A cutting die device for paper processing is a combination of a cutting die in which a predetermined pattern of grooves is carved into a base material made of plywood, plastic, etc., and pressing cutting blades and pressing rules are planted in the grooves, and a face plate facing the cutting die. It punches out a plate-shaped object such as paper or plastic sheet and simultaneously creates creases at predetermined locations.

FIG. 1 is a schematic cross-sectional view of such a device. The cutting die 1 has a pressing cutting blade 6 and a pressing rule 4 implanted in a base material 2, and sponge-like elastic bodies 5.5 are provided on both sides of the pressing cutting blade. The face plate 6 facing this comes into contact with the tip of the pressing cutting blade 3 while maintaining a positional relationship that is uniquely determined with respect to the first cutting die by the guide column 7.7 or the hinge. In addition, in order to form a good crease, a slit of a predetermined width is formed along the cutting edge of the stamping line at a portion facing the stamping line 4, and a plate-like body 8 whose peripheral portion 9 is gradually thinner is formed. Paste. “It is preferable to use paper having the same thickness as the paper to be processed for this plate-like body 8.

In the past, it was relatively easy to carve grooves on the base material using a laser beam processing device with a numerical control device to increase work efficiency, but it was necessary to process both sheets of paper to match the sharp edges of the stamping lines. The work of pasting paper on paper containers relied exclusively on manual labor, so when manufacturing a cutting die to match the paper carton to be produced, processing and alignment of both papers became a bottleneck in improving work efficiency.

The purpose of the present invention is to solve the above-mentioned bottleneck by making the work of creating both sheets of paper, aligning both sheets of paper, and pasting both sheets highly efficient, and to make the production of the entire cutting die device easier and more efficient.
Another object of the present invention is to provide a manufacturing method for obtaining a highly accurate cutting die device.

Hereinafter, the present invention will be described with reference to examples.

Figure 2 shows a front view of the cutting die. Thick solid line 11 in the figure
indicates the cutting edge of the pressing cutting blade, and the dotted line 12 indicates the tip of the pressing rule.

Guide bins 16 . . . 16 are implanted at two or more arbitrary locations on the entire surface of such a cutting die, and also at arbitrary two locations within a block surrounded by ruled lines if necessary. here 3
The reason why more than one guide bin is installed is to maintain the overall shape accuracy against expansion and contraction of both sheets. Further, providing a guide bin within a block surrounded by a stamping line is useful when a push-cutting blade is planted on the entire surface of the interleaving sheet, or when a plurality of punching dies are installed on one face plate.

Grooving of the base material of the cutting die is performed by a laser beam cutting device equipped with a numerical control device. FIG. 3 shows a schematic configuration of a rape light cutting device with a numerical control device.

A table 22 that is movable in the X and Y directions is provided on the ped 21, and a laser light emitting device 24 that irradiates laser light from above to below the table 22 is fixed. The displacement of the table 22 in the XY directions and the opening/closing control of the laser beam shutter are performed by the numerical control device 123. When using this device, the workpiece G is placed on the table 22.
By fixing the information on the command information medium 25, such as a perforated tape or a magnetic tape,
It is possible to perform predetermined groove machining. Using this laser beam cutting device equipped with a numerical control device, the grooves for installing the pressing cutting blade and the pressing rule shown in FIG. 2 and the holes for installing the guide bin are simultaneously processed.

Therefore, while inserting a push-cutting blade and a push-line into the groove of the base material,
By inserting the guide bin into the through hole 13, the cutting mold is completed.

Both sheets of paper to be pasted on the face plate facing the cutting die shown in Figure 1 are
It is manufactured using a paper pattern making device with a numerical control device and two layers of plate-shaped bodies glued together.

FIG. 4 shows a schematic configuration of a pattern making device equipped with a numerical control device.

A surface plate 27 is fixed on the ped 26, a spatula 28 is provided which can be freely displaced in the X and Y directions on the surface plate, and a numerical control device 29 is provided to control the displacement in the X and Y directions. The control method and displacement mechanism in the XY directions of this numerical control device 29 are configured the same as those provided in the laser beam cutting device described above, and the same processing can be performed by sharing the command information medium. . When using this device, you can cut the paper according to the command information by placing the paper, etc. to be created on the surface plate 27 and setting the cutter in the head 28.The cutting depth of the cutter can be adjusted according to the command information. It can also be controlled. .

FIG. 5 shows an enlarged sectional view of the structure of the two-layer plate-like body 30 for producing both papers. Adhesive 6 on one side of paper 61 that will be both sheets
2 and covered with a flexible plastic sheet 66 that does not adhere to the above adhesive.
- Place this two-layer plate-shaped body 30 with the plastic sheet i66 facing down on the table of the paper making machine, and - as shown in Fig. The cutting lines 54 and 54 are controlled so that the tip of the cutter reaches the adhesive layer 62, and only the paper 31 is cut. At the same time, the guide bin 16 in FIG.
...Plastic sheet 66 at the position corresponding to 16
Negative through holes 65...65 are formed that reach the bottom surface. These two notches ffM64.34 and negative through holes 65...6
5 is created using a program created using the same method as the control program previously used to process grooves in the base material, so the base material shown in the second row and the pattern shown in FIG. 6 completely match.

Next, the cutting die described in conjunction with FIG. 2 is set as the lower die of the punching machine, and the 2M plate-like workpiece 40 described in conjunction with FIG. 6 is placed thereon. At this time, the negative through holes 65 . . . 65 of the plastic sheet 69 are fitted into the guide pins on the base material. In this state, the plastic sheet 69 is peeled off, and the facing plate, which is the material of the push-cutting machine, is immediately removed, and the adhesive layer formed by #Il@ is attached to the face plate. After gluing, open the upper mold, remove the face plate from the mounting machine, and peel off the part sandwiched by the two cuts s and 54.34 of the interleaving paper 68, as shown in Figures 7 and 8. At the same time, as shown in FIG. 1, a cut is made obliquely to the face plate along the curve 66 in FIG. 7, and the unnecessary peripheral portion 67 is peeled off.

In this way, the face paper adhered to the face plate is completed.

According to the present invention, the alignment of the stamped lines implanted in the base material and the grooves of the base paper is inevitably performed by fitting the guide pins and the negative through holes, so that the work efficiency is significantly improved. Also,
Work efficiency has been improved because the work of pasting the interleaving paper on the face plate is done by simply peeling off the plastic sheet and then pressing down on the face plate, which will serve as the upper mold.
