Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood-type positioning device for a flat board punching machine.

[0002]

2. Description of the Related Art The punching section of a general flat board punching machine is composed of an upper board and a lower board. Equipped with pull-out chess,
In the wooden mold attached to the punching chess, a cutting blade for cutting the sheet and a ruled line blade for making a crease on the sheet are planted so as to protrude from the surface of the wooden mold. The blade height is lower than the cutting edge.

Further, a ruled line groove for forming a folding line is adhered to a face plate mounted on the lower plate at a position corresponding to a wooden ruled line blade so that a ruled line can be easily attached. Since the punching chess, the wooden pattern and the face plate have the above relationship, once the relative positions of these three are determined, the punching chess is also stored when the wooden pattern is attached to the punching chess for reuse. It is required to have the same relative positional relationship with the punched chess, the wooden pattern, and the face plate-shaped ruled line groove.

Therefore, conventionally, the punching chess is extracted from the punching portion of the flat board punching machine, and the wooden mold is taken out from the punching chess and stored. According to this method, it is necessary to create a ruled groove on the wooden mold and the face plate when the wooden mold is mounted on the punching chess when the same work is repeatedly performed. The following two methods are used to save this trouble.

The first method is a so-called "installation" in which a wooden die set in a punching chess is stored together with a face plate and the wooden die set in the punching chess is attached to the punching part. The printing method ”. In the second method, even if the wooden mold is separated from the punched chess, the punched chess 10 is moved to the same position when it is reattached, as shown in FIGS. 8 to 10.
9 and the wooden mold 108 fitted to the same
0 and 131 are formed, and the fitting portions 130 and 131 of this unevenness are formed.
The wooden mold 108 and the punching chess 109 are aligned with each other. This is a so-called "separation method" in which the wooden mold is separated from the punching chess and stored together with the surface and the face plate.

[0006]

However, in storing the wooden pattern by the "plate-setting method", which is the first method described above, face plates and expensive punching chess are required for the number of wooden patterns, which is costly. In addition to being expensive, there is a problem that the punching chess makes it bulky and the storage location is limited. Further, the punching chess itself is heavy and inconvenient to handle, so that the "plate placing method" is not widely practiced at present.

Next, according to the "separation method" which is the second method, the wooden mold can be easily attached to and detached from the punching chess, but the manufacturing error of the concave and convex fitting portions 130 and 131 and rattling at the time of mounting. There is a slight deviation due to sticking and the like, and there is a drawback that an accurate relative positional relationship with the ruled groove on the face plate cannot be obtained. Therefore, it is conceivable to make the fitting accuracy of the concavities and convexities dense, but in such a case, there is a problem that it becomes difficult to attach and detach the wooden mold to the punching chess.

Further, as shown in FIG. 11 and FIG. 12, it is conceivable that the concave and convex fitting portions 130 and 131 are formed in a chevron shape for alignment, but in this case, the concave and convex fitting portions 13 are arranged.
There is a problem in that a gap X is likely to occur between 0 and 131 and the positional accuracy in the directions indicated by reference signs A and B cannot be obtained. The present invention has been proposed in view of the above problems, and it is an object of the present invention to store a wooden mold in a small space at low cost and to mount the wooden mold with high accuracy and easily.

[0009]

In order to achieve the above-mentioned object, a wood-type positioning device for a flat board punching machine according to the present invention comprises a flat board punching machine having an upper board and a lower board. The upper board is formed by punching chess and a wooden mold fixedly supported by this,
A cone-shaped locating pin is provided on the wooden die mounting reference side of the punched chess, and when the wooden die is first set in the punched chess, the cone that follows the locating pin with the wooden die portion facing the locating pin The present invention is characterized in that a positioning fitting portion is formed by recessing the shape, and after that, the position of the wooden pattern of the upper board is determined by the positioning fitting portion.

[0010]

First, when the wooden mold is first set in the punching chess, the wooden mold facing the locating pin on the wooden mold mounting reference side with the wooden mold substantially aligned with the punching chess at a predetermined position. Press the part and set the wooden pattern in the punch chess. Then, the wood-shaped portion facing the positioning pin is recessed into a conical shape along the positioning pin.

Next, the flat plate punching machine is operated in the initially set state, the sheet is punched by a predetermined amount, and the wooden mold and the face plate removed from the punching chess are used until the next use. Saved. Then, when the wooden mold is reattached to the punching chess and used, the wooden mold is put in a state in which the recessed portion by the positioning pin when the wooden die is first attached to the punching chess is substantially matched with the positioning pin. Attach to the punching chess. Then, the recessed portion is guided by the positioning pin, and the wooden mold is set in the position initially set in the punching chess without any deviation.

After that, when the flat board punching machine is operated, the sheet can be punched with a wooden pattern while maintaining the same positional relationship as the initially set state.
