DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for assembling a punching blade for punching a printed material such as a label or a sticker printed by a rotary press or other printing machine for each unit printed material.

[0002]

2. Description of the Related Art The work of punching out printed materials such as printed labels and stickers for each unit printed material has been conventionally performed and is known. This punching work is performed by setting a punching blade incorporated in a press machine on a punching table formed by laminating bakelite on an iron plate, and a label sent to the punching table by the punching blade at each pressing operation of the press machine. A printed material such as a sticker was punched for each printed material unit. The previously known method and apparatus for assembling a punching blade employs means for directly screwing a blade having a punching blade directly attached to a tooth fixed to a press machine.

[0003]

In the above-described conventional method and apparatus for assembling a punching blade, the screw holes provided in the teeth fixed to the press machine are formed in the periphery of the teeth. It must be the same size as the cheese,
This blade type also needs a countersunk hole for receiving the screw corresponding to the screw hole of this cheese, and as a result, regardless of the size of the punching blade, the problem is that a blade type of the same size as the cheese is always required. There is. In addition, since the incorporation of the punching blade into the blade die and the formation of the groove for the driving blade of this blade die are performed manually, the formation of the groove for the punching blade, which is particularly small compared to the blade die, is not particularly effective. There is a problem that it is difficult to accurately adjust the vertical and horizontal positions. That is, since the printed matter always flows parallel to the parallel edges of the cheese and the center position always flows at the center position of the cheese, there has been a problem that the groove of the punching blade requires extremely skill.

[0004] In the present invention, in view of the problems of the above-described conventional method and apparatus, the size of the cutting die is determined according to the size of the punching blade, and the setup time is shortened by facilitating the incorporation into the cheese. Further, it is an object of the present invention to provide a novel punching blade assembling method and apparatus which can reduce waste of material.

[0005]

In order to achieve the above object, according to the assembling method of the present invention, a blade base made of a rectangular plate having the same size as the cheese is provided, and the blade base is provided with a plate corresponding to the screw hole of the cheese. While forming a hole, forming a number of spring pin receiving holes on the center line between any one of the parallel edges, while also forming a number of screw hole rows in parallel on both sides of this spring pin receiving hole row, A spring pin receiving hole corresponding to one of the spring pin receiving holes in the row of spring pin receiving holes is formed in a blade mold having a size corresponding to the size of the punching blade. The spring pins fitted into the corresponding spring pin receiving holes of the above-mentioned many spring pin receiving holes are fitted to position the blade dies, and the opposite edges of the blade dies are screwed down with a holding plate. It is characterized in that it has the appropriate screw holes row of holes to be fixed by screwing.

In the assembling apparatus of the present invention, a plurality of spring pin receiving holes are provided on the center line, and a plurality of screw holes are provided in parallel on both sides of the row of spring pin receiving holes. It has a countersink at the corresponding position, a blade base consisting of a square plate similar to Cheese, and a punching blade,
A blade die having a spring pin receiving hole for receiving a spring pin fitted in the spring pin receiving hole of the blade base, and a screw which is screwed into an appropriate screw hole of a screw hole row of the blade base to form the blade die. A holding plate fixed to the blade base is provided, and the blade base is screwed to the teeth.

[0007]

The spring pin is inserted into the spring pin receiving hole formed on the center line of the blade base corresponding to the spring pin receiving hole formed in the blade die, and the spring pin is inserted into the spring pin receiving hole of the blade die. And position the blade mold. Then, the holding plate is fixed to an appropriate screw hole of the blade base with a screw, and the blade base is screwed to the tooth. On the other hand, after the blade base is screwed to the cheese in advance, the blade mold may be attached.

[0008]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In the figure, reference numeral 1 denotes a cheese, which is mounted on a press for punching and pressing printed labels, stickers and the like, and is similar to a known one. Screw holes 2 and 2 are formed at appropriate positions on the periphery of the cheese. In the figure, reference numeral 3 denotes a blade base, which is formed in a square shape having the same dimensions as the above-mentioned cheese. A large number of spring pin receiving holes 5 are formed on a center line parallel to the longitudinal edge of the blade base 3, and an appropriate number of spring pins 7 are fitted into these spring pin receiving holes 5. A screw hole array is formed by a large number of screw holes 6 in parallel with both sides of the five rows of spring pin receiving holes.

In the figure, reference numeral 8 denotes a blade die formed by stacking two resin plates, and has a rectangular shape smaller than the above-mentioned blade base. Depending on the size and the number of punching blades 9 mounted on this blade die,
Its size is determined. A groove having the same shape as the punching blade is formed in the blade die 8, and a punching blade 9 is implanted and mounted in the groove. The blade die 8 has a plurality of spring pin receiving holes 10 corresponding to any of the numerous spring pin receiving holes 5 formed in the blade base 3. 7 is fitted to position the blade mold 8.

In the figure, reference numeral 11 denotes a pressing plate which is formed by bending a plate material and comprising a pressing portion 12 and a fixing portion 14 having a long hole 13.
5 is screwed into the screw hole 6 of the blade base 3 through the long hole 13 so that the blade die 8 is mounted on the blade base 3.
The blade base 3 on which the blade die 8 is mounted in this manner is overlapped on the cheese 1 so that the screw hole 2 and the countersink hole 4 are aligned with each other, and mounted on the cheese 1 with screws (not shown).

[0011]

According to the method and the apparatus of the present invention constructed as described above, a blade base having a spring pin receiving hole and a screw hole is prepared, and a blade die is aligned with the blade base by a spring pin. After that, since it is mounted with the holding plate, the positioning and mounting of the blade mold are extremely easy, and there is an effect that the setup time of the assembling operation can be reduced.
At the same time, the size of the blade die can be determined according to the size of the punching blade, so if the punching blade is small, a small blade die may be used, and there is no need for a size matching the cheese as before, so the material is This has the effect of eliminating waste.
