Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a punching die holding device that easily and reliably fixes the punching die in a predetermined position in a die cutting machine that punches out labels, etc. into desired shapes. be.

Conventionally, in this type of cutting machine for labels, etc., a punching die having the desired shape to be punched, such as a circle, oval, square, or other polygon, is aligned with the face plate of the die cutting machine body. hand,
It is fixed in a predetermined position by mold holders installed on the outer surface of this face plate through three or more bolts or the like.

Therefore, in this method of holding the mold, when replacing the mold or changing the mounting position, loosen the bolts that support the linear holder to the main body face plate. Due to this zero weight, the port T- (T-bolt) slides and descends along the dovetail groove provided on the face plate, and tools such as monkey keys and spanners are required to tighten and loosen the bolt. Another disadvantage is that it is difficult to make adjustments with one hand.

Further, since the mold is provided outside the face plate, a large stress is applied to the mold holder, which has the disadvantage that the mold holder becomes very strong.

In view of this, the present invention enables the adjustment of the attachment position of the mold holder to the face plate to be easily and finely adjusted with one hand by simply rotating the bundle, and will be described below based on examples. .

In the figure, 1 is the main body of a die-cutting machine that punches labels, price tags, playing cards, notebooks, and other printed matter (hereinafter referred to as labels, etc.) into squares, circles, ovals, and other various shapes. 2 or 3 or more die holders that work together to hold the punching die, a surface plate 9 for placing a label or the like on the die, and a label placed on the surface plate 9. The mold holder 3 is comprised of a punching plate 10 that presses a mold with a predetermined pressure. Provided on the side opposite to.

This is done by erroneously installing an arc-shaped long groove 2a at the position where the mold holder is installed in advance on the inner surface of the face plate 2, but the length of this long groove 2a depends on the amount of adjustment of the mold holder with respect to the face plate. However,
This should be more than twice the adjustment sliding amount of the normal type holder.

The number of long grooves 2a to be carved is made to match the number of mold holders provided on the hair.

Also, an arcuate long hole 2b for shaft insertion is drilled concentrically with the long groove 2a in the longitudinal direction of the long groove 2a, and the length of this arcuate hole 2b is set to the length of the mold holder. The amount of adjustment is determined to be the maximum, and the bottom of the long groove 2a is located on both the inner and outer periphery of the long hole 2b.

An arc-shaped rack 4 having an arc shape concentric with the arc of the long groove 2a is slidably inserted into the long groove 2a, and the outer peripheral surface or circumferential surface of the arc-shaped rack 4 is slidably inserted. Teeth 4a are carved on approximately the entire length or a part thereof, and a shaft hole 4b is bored in a part of this rack 4 or in one end thereof as shown in the figure, and the shaft hole 4b of the rack is opened from the elongated hole 2b provided in the hair of the head. A threaded portion 5 passes through the bolt 5 and is provided at the tip of the bolt 5.
A is screwed onto a part of the sharpening holder 3 to enable the mold holder 3 to slide freely on the inner plate 2, and is tightened in a predetermined position by the bolt 5.

By providing a pinion 6 in the hair so as to mesh with the teeth 4a of the rack 4 fitted into the long groove 2a above the head, and rotating the bundle H which is bored outside the neck using the pinion 6 via the shaft 7. The rack 4 meshed with the pinion 6 is caused to slide within the long groove by the rotation of the pinion 6.

A sliding rod 3a having a claw for holding the mold at the tip is slidably inserted into the mold holder 3, and a rack 3b is attached to a part of the sliding rod 3a in the longitudinal direction. A pinion P is built into the mold holder 3 so as to mesh with the rack 3b, a worm 8 is directly meshed with the pinion P, and the worm shaft 8a is made to protrude outside the mold holder to attach the bundle. Although the pinion P is fixed, a worm wheel may be provided coaxially with the pinion P, and the worm 8 may be meshed with the worm wheel.

In order to set the punching die K having the desired shape to be punched into the main body 1 in the device having the above structure, first place each die holder at the desired position on the hair depending on the size of the label etc. to be die-cut. move it to

This is done by rotating the bundle H on the hair provided for each type holder to the left or right.

That is, as the bundle H rotates, the rack 4, which is meshed with a pinion 6 provided at the end of the bundle shaft, slides within the long groove 2a in accordance with the rotation of the pinion.

When this rack slides, a shaft passes through the rank, and the rack and mold holder are fixed via this shaft, so the mold holder also slides together and moves along the circumferential direction of the hair. be.

After each mold holder has been moved to a desired position in this manner, the sliding rods 3a are then moved in and out, and the mold K is firmly held between the tips of the sliding rods.

According to the present invention, the mold holder provided on the inner panel of the main body can be easily moved with one hand by simply rotating the bundle provided at the end of the pinion shaft using an arc-shaped rack and a pinion that meshes with the rack. It also has the advantage that fine adjustments can be made easily, and since the mold holder is provided inside the inner plate, the stress applied to the mold holder is also reduced.
