A plurality of elastic bodies 35 made of rectangular parallelepiped sponge are fixed and protruded from the upper surface of the body 1 at appropriate intervals.

Note that the elastic body 35 is not limited to the above-mentioned sponge, but may be a coil spring or the like, as long as it has elasticity. In addition, guide holes 36 are bored in the four corners of the movable mold plate 31, and a cylindrical guide shaft 37 is inserted into these guide holes 36.
The lower end of the screw is screwed into the screw and protrudes upward. After these guide shafts 37 are attached to the movable template 31, a smooth resin surface layer 38 such as Teflon is provided on the entire lower surface of the template 31.

As described above, the mold plate 31 having the elastic body 35 and the guide shaft 37 protruding from the upper surface side is assembled to the base plate 30, and the movable mold 1
It constitutes 0. That is, the upper end of each guide shaft 37 is inserted into the corresponding guide hole 34 drilled in the substrate 30, and the nut 39 is inserted into the threaded portion formed on the outer peripheral surface of the upper end of each guide shaft 37.
As shown in FIG. 1, the movable template 31 is assembled to the base plate 30 by locking the nut 39 into the upper recess 34a of the guide hole 34. In this state, the outer peripheral end surface of the template 31 has a shape 32 projecting downward from the substrate 30.
By compressing the elastic body 35, the movable template 31 is pushed into the inner part 33 surrounded by the bungetsu 32. On the other hand, when the pressing force is released, the elastic body 35 lowers it by the urging force and returns to the original position shown in FIG. In this original position, the movable template 31 has at least the resin surface layer 38 on the lower surface side
It is set to protrude downward from the downward tip surface of the. Therefore, when matching the movable mold 10 and the fixed mold [l] through the punching paper 1, the movable mold plate 31 is inserted before the Bungetsu 32.
is in contact with the punched paper 1, and both upper and lower surfaces of the punched paper 1 are held between the upper surface of the product clamping part 13 of the fixed type It.

Next, the action of removing punching chips by the above-mentioned device will be explained with reference to FIGS. 7 and 8.

As shown in FIG. 7, a sheet of punched paper (sheet) that has been punched out in advance in the shape of a predetermined punched product P in the punching section is held at one end by a transfer means 50 to remove the punched waste. The paper is transferred to a detaching device, stopped at a predetermined position on the upper surface of the template 12 of the fixed die 11, and the punched paper l is placed on the upper surface of the template 12. Then,
When the movable mold 10 is lowered, first, the resin surface layer 38 of the mold plate 31 that is most protruding toward the lower end comes into contact with the upper surface of the punched paper 1. At this time, the shape of the template 3 is approximately the same as the shape of the punched product P, and the outer shape is only slightly smaller, and the fixed template 12 on the other lower side is also the same as the template 31. Since they have the same shape, the entire upper and lower surfaces of the punched product P of the punched paper I are sandwiched between the two templates 12 and 31.

In this way, when the movable die IO is further lowered with both the upper and lower sides of the punched paper 1 being sandwiched between the templates 12 and 31,
The template 31 compresses the elastic body 35 and rises along the inner surface of the moon 32, pushing it into the inner part 33. At this time, since the biasing force of the elastic body 35 is applied to the punched paper 1 via the template 31, pressure is applied evenly to the entire sandwiched punched paper 1.

When the moon 32 comes into contact with the punching paper L and descends, as shown in FIG. The surrounding punching waste 2 is separated, leaving a portion.

After the above operation, when the movable mold 10 is raised, the mold plate 31 is pressed by the repulsive force of the elastic body 35 and returns to the position protruding downward from the moon 32. Due to the operation of this template 31, even if the punched product part P separated from the punching waste 2 is attracted to the temporary template 31 and tries to rise with the movable die 10, it is firmly pushed onto the fixed template 12. returned. In addition, since the surface of the template 31 is made of a smooth resin layer 38 such as Teflon,
There is no fear that the punched product portion P will stick to the surface of the template 31.

Effects of the Invention As is clear from the above explanation, according to the punching waste removal device according to the present invention, the fixed template is composed of one rectangular flat plate, and the punched paper is inserted into the flat plate. A product holding part, which has an outer shape that is approximately the same as the punched product part and slightly smaller in size than the part that will become the punched product, is formed by grooves along the outer periphery of the above-mentioned outer shape, except for one side that corresponds to the conveying means. provided and formed,
A support rod part is formed that connects the product holding part and the outer frame of the mold plate facing each other across the groove, and one end of the fixed mold plate is placed on the fixed receiving plate fixed to the machine body. At the same time, the opposite end of the template is placed on a movable receiving plate fixed to a moving means such as an air cylinder, and the movable receiving plate is moved to the fixed receiving plate side by the moving means. , simply place the fixed template between the h','e V plate and the movable receiving plate.
It is possible to perform positioning extremely easily and position and fix in a predetermined position. In addition, since the outer end surface of the product clamping part that engages with the fixed template plate is surrounded by an outer frame through a groove, there is no risk of damage to the outer end surface, and punching waste can be accurately removed. It has the advantage of being able to

Furthermore, since the fixed mold plate is rectangular and the portion to be placed on the movable receiving plate has a linear end, the shape of the movable receiving plate can be simplified, and the pressing force by the moving means can also be reduced. It has various advantages such as being able to be applied evenly to the board.

Furthermore, we provided a product holding part of a fixed template with approximately the same shape as the product part to be punched, and a template attached to a movable mold, and created a structure in which the entire sides of the punched product part were sandwiched between them. Even in the case of a sheet that is so-called weak and easily bent, it can be punched out accurately along the die-cutting line while maintaining the flatness of the sheet.

Furthermore, since the punched product part is entirely sandwiched on both sides, it has various advantages such as no wrinkles or the like.
