TECHNICAL FIELD OF THE INVENTION
The present invention relates to a face plate device for fixing a face plate for punching paper material to a pedestal.
[0002]
[Prior art]
In the process of manufacturing a paper box such as an assembly box, a paper material punching process of processing a paper material into a blank of a predetermined shape includes a cutting die having a cutting blade for making a cut line in the paper material and a streak blade for making a folding line. Is pressed against a paper material placed on a face plate that receives these blades.
[0003]
FIG. 7 shows an example of a paper material punching apparatus for processing a paper material in this manner.
[0004]
The punching device 70 includes a cutting die 71 provided with a cutting blade and a streak blade corresponding to a blank having a predetermined shape, an elevating part 72 on which the die 71 is installed, and a pedestal provided below the elevating part 72. 74 and a face plate 73 mounted on the pedestal 74. A groove is formed on the surface of the face plate 73 by attaching a backing sheet, the groove corresponding to a stripped blade.
[0005]
The paper material K is conveyed with its end supported by a clamp provided in a circulation chain or the like, and is brought onto the surface of the face plate 73. Then, as the elevating unit 72 descends, the punching die 71 is pressed against, and cuts and folds are formed and punched.
[0006]
In such a paper material punching apparatus, the work of attaching a backing sheet to a face plate to form a groove corresponding to a streak is generally called face digging, and is a precise, time-consuming and troublesome work. When a blank of the same type is to be processed again, the face plate having been dug out is removed from the apparatus and stored, and this is repeatedly used.
[0007]
In other words, the face plate is naturally robust enough to withstand the impact pressure at the time of receiving the cutting blade and the streak blade. Improvements and reductions in unit cost have been made.
[0008]
As this type of face plate and pedestal, there is, for example, a paper receiving blank receiving plate disclosed in Japanese Patent Publication No. 6-50159. This paper receiving die receiving plate is configured to regulate the fixing position of the face plate main body by a guide provided on the surface of the pedestal, and to attract the face plate main body by a magnet provided on the surface of the pedestal.
[0009]
[Problems to be solved by the invention]
By the way, the face plate as described above needs to be accurately positioned with respect to the pedestal in order to correspond to the die.
[0010]
Therefore, the face plate requires strict dimensional accuracy so as to exactly match the guide provided on the base, and the processing cost is extremely high.
[0011]
Some guides are configured so that they can be attached to and detached from the pedestal as appropriate.However, when such a guide is used, the mounting position and angle of the guide are slightly different, and the fixing position of the face plate is changed. The case where it shifted was remarkable.
[0012]
Further, when the face plate is attracted by a magnet provided on the surface of the pedestal as disclosed in Japanese Patent Publication No. 6-50159, when the face plate is positioned or removed from the pedestal, the attraction force is an obstacle. And there is also an inconvenience that it becomes difficult to handle the face plate.
[0013]
Further, such a magnet is usually embedded with a large number of holes perforated over the surface of the pedestal, and the strength and durability of the pedestal may be reduced by perforating the holes into which the magnet is embedded. .
[0014]
Also, when punching a paper material whose end is clamped by the clamp's grip, it is desirable that the clamp's grip and the face plate be as close as possible. This is because the portion of the paper material from the grip of the clamp to the face plate cannot be punched out and is wasted.
[0015]
In view of these problems, an object of the present invention is to provide a face plate device for fixing a face plate for punching a paper material to a pedestal, which can efficiently fix the face plate.
[0021]
[Means for Solving the Problems]
Invention herein described in the first aspect, in the face plate device for fixing a paper material punching faceplate on a pedestal, the pedestal includes a recess corresponding to the clamp portion of the clamp for supporting an end portion of paper material, said recess And a projection adjacent to the projection, wherein the projection is provided with a guide piece for regulating the face plate.
[0022]
As described above, according to the face plate device of the present invention, the pedestal includes the concave portion corresponding to the grip portion of the clamp supporting the end of the paper material, and the convex portion adjacent to the concave portion, and the convex portion has the face plate. Is provided, the face plate is positioned near the concave portion of the pedestal, and when punching a paper material, the face plate and the grip portion of the clamp approach each other. As a result, the paper material is fully utilized.
[0023]
In other words, the paper material between the clamp edge and the face plate cannot be punched out and is wasted, but in the present invention, the fixing position of the face plate is set by the guide piece provided on the convex portion. Thus, waste of such paper materials is reduced.
[0032]
