TECHNICAL FIELD OF THE INVENTION
The present invention relates to a processing method and a processing apparatus for a punching die used for obtaining a book (so-called carton) by punching a base paper for a paper container, and in particular, to a punching die forming the punching die together with the punching die. The present invention relates to a method and apparatus for processing a face plate (hereinafter, simply referred to as “face plate”).
[0002]
[Prior art]
The paper container is manufactured, for example, by printing a pattern to be attached to the paper container on a base paper, punching out a print book from the base paper, folding the print book into a predetermined shape, and gluing a predetermined portion.
[0003]
As shown in FIG. 5, when the printing book 100 is punched from the paperboard for a paper container, a punching device including a punching die 60 corresponding to a male die and a face plate 70 corresponding to a female die is usually used.
[0004]
The punching die 60 includes a plurality of punching blades (cutting blades) 62 arranged corresponding to the planar shape and size of the printing book 100 to be punched, and a ruled line (pressed rule) at a folded position in the printing book 100. A plurality of ruled line blades 64 are provided corresponding to the portions to form the 90.
[0005]
On the other hand, the face plate 70 has a ruled line groove 72 formed corresponding to the ruled line blade 64 arranged on the punching die 60, and the face plate 70 is made of a base material 80 made of a metal plate having a flat upper surface. Fixed on top. The base material 80 is arranged such that the normal direction of the upper surface substantially matches the height direction of the punching blade 62.
[0006]
The planar shape of the face plate 70 corresponds to the planar shape of the printing book 100 to be stamped. In addition, the size of the face plate 70 in a plan view is such that the paperboard base paper is caught between the punching blade 62 and the face plate 70 so that the mark of the face plate 70 is formed on the book 100 or wrinkles are generated. In order to prevent this, the size of the book 100 is slightly smaller than the size in plan view. An uphill slope region 74 is formed at an edge of a region of the face plate 70 located on the inner side in plan view from the contact line of the cutting blade by the cutting die 60.
[0007]
As used herein, the term “contact line for punching blade by the die” refers to a normal line on the upper surface of the base material to which the face plate is fixed, and is an outer surface of the punching blade arranged on the die. Means the normal passing through the outer surface when viewed from the printed book).
[0008]
As the face plate material, a synthetic resin such as a phenol resin or a sheet-like fibrous material (for example, a paperboard called a press board) can be used. Quality materials are mainly used.
[0009]
In manufacturing a face plate using a face plate material made of a fibrous material, first, a fibrous material is attached to a substrate using a water-soluble adhesive. Next, using a carbon paper or the like, the positions of the cutting blade and the ruled line blade in the cutting die are press-transferred to the face plate material. The arrangement position of the transferred ruled line blade is a position where a ruled line groove is to be formed, and the arrangement position of the punching blade is a portion corresponding to the extraction blade contact line. The formation and the formation of the above-mentioned inclined region are performed.
[0010]
As described in Patent Literature 1 and Patent Literature 2, the formation of the ruled line grooves is performed using a rotary saw blade, and the formation of the inclined region is performed using a cutter knife after forming the ruled line grooves. Finally, the face plate material is moistened to reduce the adhesive strength of the adhesive, and unnecessary portions are removed with a spatula or the like to obtain a face plate.
[0011]
When a synthetic resin is used as the face plate material, automatic processing using a luter is also performed.

JP-A-9-150312
[Problems to be solved by the invention]
The fibrous material is suitable as a face plate material because it can be obtained at a low cost as described above. However, in the case of a face plate using the fibrous material, work for fine adjustment after mounting on a punching device is performed. And correction work are often required, and the processing time for obtaining a finally used face plate tends to increase.
[0013]
If there is fluff inside or around the crease groove formed by the saw blade, it will be difficult for the crease blade to sufficiently push the base paper for the paper container into the crease groove, or the fuzzed portion will have traces of the base paper or the booklet. The above-mentioned fine adjustment and correction work is particularly important for the inside or the periphery of the ruled line groove because the quality of the paper container is deteriorated due to the above.
[0014]
It is also conceivable to fabricate the face plate by processing the fibrous material with a luter, but if the fibrous material is processed with a luter, fuzzing occurs on the processed end face. Requires fine adjustment and correction work.
[0015]
Therefore, an object of the present invention is to provide a method and an apparatus for processing a punching face plate capable of obtaining a face plate in a relatively short time even when a fibrous material is used as the face plate material.
[0016]
[Means for Solving the Problems]
The present inventors have solved the above problem by using a cutter and a luter together.
[0017]
Hereinafter, the present invention will be described. Note that reference numerals in the accompanying drawings are added in parentheses to facilitate understanding of the present invention, but the present invention is not limited to the illustrated embodiments.
[0018]

A second moving mechanism 40 capable of reciprocating in a second direction D2 orthogonal to the second moving mechanism 40 is configured.
[0042]
Since the processing apparatus 50 having the above-described configuration is suitable as an apparatus for manufacturing a face plate using a face plate material made of a fibrous material, the face plate material made of a fibrous material is hereinafter processed into a face plate by the processing apparatus 50. The steps to be performed will be described.
[0043]
First, as shown in FIG. 2A, a first step of fixing a face plate material 1A made of a fibrous material on a base material 5 is performed. The fixation of the face plate material 1A on the base material 5 can be performed using a water-soluble adhesive as in the related art.
[0044]
Next, using a carbon paper or the like, the positions of the cutting blade and the ruled line blade in the cutting die are press-transferred to the face plate material 1A.
[0045]
Next, the face plate material 1A and the base material 5 are fixed on the surface plate 7, and the processing head 20 is moved to a predetermined position by the first moving mechanism 30 and the second moving mechanism 40, and then shown in FIG. As described above, the area where the ruled line groove is to be formed in the face plate material 1A, that is, the position where the ruled line blade is transferred to the face plate material 1A is cut by a cutter to form side walls on both sides in the width direction of the ruled line groove. Perform two steps.
[0046]
In the illustrated example, two single-sided cutters 15A are used, and the cutter 15A is formed such that the surface opposite to the surface on which the blade is formed is located on the side wall side of the ruled line groove. A cut is made in the face plate material 1A so that the side walls are substantially vertical, and the side walls on both sides in the width direction of one ruled line groove are simultaneously formed.
[0047]
The ruled line groove includes a groove extending in the first direction D1 shown in FIG. 1 and a groove extending in the second direction D2 shown in FIG. It is preferable that the cutter 15A be configured to be able to rotate the orientation in a plan view by a desired angle. Alternatively, it is possible to hold four cutters at the same time, appropriately select one or two cutters from among these four cutters, and perform processing with the other three or two cutters stored. It is preferable to configure so as to be able to.
[0048]
In FIG. 2 (B), in order to make it easy to see the arrangement position of the ruled line blade transferred to the face plate material 1A, smudging is applied to the position.
[0049]
Next, after the router 10 is moved to a predetermined position by the first moving mechanism 30 and the second moving mechanism 40, as shown in FIG. 2C, the face plate material 1A in the area where the ruled line groove 72 is to be formed. Is performed by the luter 10. FIG. 2C shows a relative positional relationship between the straight blade 11A and the face plate material 1A when the face plate material 1A is removed by the luter 10 having the straight blade 11A, and an arrow A in FIG. The rotation direction of the straight blade 11A is shown. In the straight blade 11A, a blade not shown extends in a direction parallel to the rotation axis.
[0050]
By performing the second step and the third step described above, the ruled line groove 72 can be formed.
[0051]
Next, a fourth step of forming an upwardly sloped region at the edge of a region of the face plate material 1A that is located on the inner side in plan view from the punching blade contact line is performed. This fourth step can be performed using the luter 10 or using the processing head 20.
[0052]
In the case where the fourth step is performed using the luter 10, as shown in FIG. 3A, the inclined area 74 is formed by using a luter 10 having a conical blade (machining tool) 11 </ b> B as the luter 10. Can be formed. Considering that the size of the face plate in plan view may be smaller than the size of the print book in plan view, as shown in FIG. 3B, the shape of the face plate provided with the trapezoidal blade 11C is shown. Forming the inclined region 74 using an end mill facilitates the alignment of the luter 10 and also, when punching a book, the paperboard for a paper container is pressed against the inclined region 74 to cause a pressing mark on the book. It is preferable from the viewpoint that attachment is easily suppressed.
[0053]
On the other hand, when performing the fourth step using the processing head 20, it is necessary to relatively incline the surface plate 7 and the processing head 20 with each other. It is preferable to have at least one of a rotation axis extending in D1 and a rotation axis extending in the second direction. By turning the processing head 20 around the rotation axis by a predetermined angle, it becomes easy to form the inclined region 74 using the processing head 20.
[0054]
After that, when the unnecessary face plate material 1A remains outside the inclined region 74 formed in the fourth step, a fifth step of removing the unnecessary face plate material 1A by, for example, the luter 10 is performed.
[0055]
In this manner, the face plate can be obtained by performing the first to fourth steps or the first to fifth steps by the processing apparatus 50. Even when the face plate material 1A made of a fibrous material is used, the ruled line groove 72 can be formed without causing fluff on the side wall and the periphery of the ruled line groove 72. Therefore, the face plate was mounted on a punching device. It becomes easy to reduce the amount of work for fine adjustment or correction that is required later. As a result, a desired face plate can be obtained within a relatively short time.
[0056]
In addition, since the formation of the inclined region 74 and the removal of the unnecessary face plate material 1A in the case where the unnecessary face plate material 1A remains outside the inclined region 74, which is conventionally performed manually, are automated, Also from this point, a desired face plate can be obtained in a relatively short time. Further, the quality of the manufactured face plate is also stabilized.
[0057]
The order of the second step, the third step, the fourth step, and the fifth step is not limited to this order, and can be appropriately changed without changing the order.
[0058]
In addition to the method for processing a faceplate for punching according to the present invention, the method for processing a faceplate for punching according to the present invention can be carried out by hand, in addition to the method for processing. Even in this case, it is possible to obtain a desired face plate in a relatively short time as compared with the time required for manually manufacturing the face plate according to the conventional method.
[0059]

[0061]
Note that among the members illustrated in FIG. 4, the same members as those illustrated in FIG. 2B are denoted by the same reference numerals as those used in FIG. 2B, and description thereof is omitted. .
[0062]
When the unnecessary face plate material remains outside the inclined region, it is preferable to completely remove the unnecessary face plate material from the viewpoint of preventing the occurrence of molding failure at the time of punching a printing book. On the other hand, from the viewpoint of repeatedly using the base material, as a face plate material layer having a thickness capable of functioning as a cushioning material for preventing the punching blade and the base material from directly contacting each other is formed in the thickness direction. It is preferable to partially remove the lower part.
