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 in a base material made of plywood, plastic, etc., and a push-cutting blade and a press rule are planted in the grooves, and a face plate that faces the cutting die. It punches out a plate-like material 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 press cutting blade 3 and a press rule 4 on the base material 2.
and a spongy elastic body 5 on both sides of the pushing cutting blade.
5. The corresponding face plate 6 maintains a positional relationship that is uniquely determined with respect to the first cutting die by the guide columns 7, 7 or the hinge, and the pressing cutting blade 6
touches the tip of the In addition, in order to form a good crease, a slit of a predetermined width b is formed along the cutting edge of the stamping score 4 at a location opposite to the stamping score 4, and the thickness of the peripheral portion 9 is gradually reduced. Paste. It is preferable to use paper having the same thickness as the paper to be processed for this plate-like body 8.

Conventionally, it has been relatively easy to improve work efficiency by using a laser beam processing device equipped with a numerical control device to carve grooves in the base material, but it has been relatively easy to improve the work efficiency by using a laser beam processing device equipped with a numerical control device. The work of attaching paper to the face plate had to be done entirely by hand, so when manufacturing a cutting machine to match the paper container to be manufactured, the processing and positioning of the face paper became a bottleneck in improving work efficiency.

The purpose of the present invention is to eliminate the above-mentioned bottlenecks and make the production of the entire cutting die easier and more efficient by increasing the efficiency of the operations of creating the facing paper, positioning the facing paper, and pasting the facing paper, and to make the production of the entire cutting die 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 explained with reference to examples.

Figure 2 shows a front view of the cutting die. In the figure, a thick solid line 11 indicates the cutting edge of the pressing cutting blade, and a dotted line 12 indicates the tip of the pressing rule. Guide pins 13 are installed at two or more arbitrary locations on the entire surface of such a cutting die, and at arbitrary two locations within a block surrounded by ruled lines if necessary.
...13 is implanted. The reason why three or more guide pins are implanted here is to maintain the overall shape accuracy against expansion and contraction of the facing paper. Furthermore, providing a guide pin within a block surrounded by stamping lines is useful when a stamping blade is planted on the entire surface of the face 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 laser beam cutting device with a numerical control device.

A table 22 that is movable in the XY directions is provided on the bed 21, and a laser emitting device 24 that irradiates laser light from above to below the table 22 is fixed. XY of table 22
A numerical controller 23 controls the directional displacement and the opening/closing of the laser beam shutter. When using this device, the workpiece G is fixed on the table 22,
Predetermined groove machining can be performed by inputting information from a command information medium 25 such as perforated tape or magnetic tape made in advance. 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 pins are simultaneously processed.

Therefore, by implanting a pressing cutting blade and a pressing rule into the groove of the base material and implanting a guide pin into the through hole 13, the cutting die is temporarily completed.

The facing paper to be pasted on the face plate facing the cutting die shown in FIG. 1 is produced using a pattern making device with a number control device and two layers of plate-shaped bodies adhered to each other.

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 bed 26, and a head 28 is provided on the surface plate, which is movable in the X and Y directions.
A numerical control device 29 is provided to control displacement in the XY directions. The control method of this numerical control device 29 and
The displacement mechanism in the XY directions has the same structure as that provided in the laser beam cutting device described above, and if the command information medium is shared, the same processing can be performed. When using this device, by placing the paper to be produced on the surface plate 27 and setting the cutter on the head 28, the paper can be cut according to the command information, and the cutting depth of the cutter can be adjusted based on the command information. It can also be controlled.

Fig. 5 shows a two-layer plate-like body 30 for producing a face paper.
An enlarged sectional view of the configuration is shown. An adhesive 32 is applied to one side of a paper 31 that will serve as a facing paper, and a plastic sheet 3 that is flexible and does not adhere to the adhesive is placed on top of that.
3.

This two-layer plate-like body 30 is covered with a plastic sheet 33.
Place the cutter face down on the table of a pattern making device equipped with a numerical control device, and as shown in Fig. 6, cut two cut lines 34, 34 of width b at the locations where folds are to be formed, using adhesive at the tip of the cutter. Only the paper 31 is cut under control so as to reach the layer 32. At the same time, through holes 35 reaching the bottom of the plastic sheet 33 are formed at positions corresponding to the guide pins 13...13 in FIG.
. . . 35 is formed to complete a two-layer plate-shaped workpiece 40 that becomes a facing paper. These two cut lines 34, 34
For the through holes 35 and 35, first, based on the control program used for grooving the base material, create a program by reversing it inside out, and use that reversal program to create the pattern shown in Figure 6. do. Therefore, when used upside down, it completely matches the base material shown in FIG.

Next, the cutting die described in conjunction with FIG. 2 is set as the lower die of the press-cutting machine, and the two-layer plate-like workpiece 40 described in conjunction with FIG. 6 is placed thereon with the paper sheet facing downward. At this time, the through holes 35 of the plastic sheet 33 are fitted into the guide pins on the base material. In this state, the plastic sheet 33 is peeled off, a face plate serving as the upper die of the press-cutting machine is immediately placed, and the adhesive layer exposed by the peeling is adhered to the face plate. After gluing, open the upper mold and remove the face plate from the machine.
As shown in FIGS. 7 and 8, the portion of the facing paper 38 sandwiched by the two cut lines 34, 34 is peeled off and removed.
At the same time, as shown in FIG. 19, curve 3 in FIG.
A cut is made obliquely to the face plate along line 6, and the unnecessary peripheral portion 37 is peeled off and removed. 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 through holes, so that the work efficiency is significantly improved. In addition, work efficiency has been improved because the work of pasting the face paper onto the face plate is accomplished by simply peeling off the plastic sheet and then pressing down the face plate, which will serve as the upper mold.

Further, according to the present invention, a pattern making device is provided which creates a program for flipping the laser light cutting device used to process the grooves in the base material, and processes the facing paper using the program. It is possible to control the process, save the trouble of creating a program, and moreover, it is possible to perform accurate face paper processing with no difference in size.
