Abstract

(57) [Abstract] [Purpose] To provide a die sheet mounting device that facilitates replacement and orientation correction of a die sheet having a punching blade. [Structure] A pair of band clamps 4 that can be tightened are attached to the outer periphery of a die roll 1. A pair of band clamps 4 are attached to both ends of the outer periphery of the die sheet A wound around the outer periphery of the die roll 1, and the die sheet A is fixed by tightening the band clamps 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a die sheet mounting device having a punching blade.

[0002]

[Prior art]

 Generally, in a label printing apparatus, after printing is performed on a label paper laminated on a separator, the label paper is punched into a predetermined shape, and the scraps are peeled off from the separator.

A punching device is used for punching a label sheet. As this punching device, a laminate paper consisting of a separator and label paper was sent between the die roll and the flat anvil, and the die roll was rotated at a peripheral speed equal to the moving speed of the laminate paper to provide it on the outer periphery of the die roll. It is known that only the label paper is punched with a punching blade.

Some of the above-mentioned punching devices are those in which a die sheet having a punching blade is attached to the outer periphery of a die roll. Conventionally, when attaching the die sheet, double-sided adhesive tape is used to adhere the entire surface to the outer periphery of the die roll, or a clamp is attached to the groove provided on the outer periphery of the die roll, and both ends of the die sheet are held by the clamp. I am trying to do so.

[0005]

[Problems to be solved by the device]

 By the way, when attaching and removing the die sheet as described above, it is extremely difficult to attach and detach the die sheet, and it takes time and effort to replace the die sheet, which often causes damage to the die sheet. There was also a problem that it took a lot of time to fix.

It is a technical object of the present invention to solve the above-mentioned conventional problems and to provide a die sheet mounting device that can easily replace the die sheet and correct the direction of the punching blade.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention adopts a structure in which a pair of circular band clamps capable of tightening both ends of a die sheet wound around the die roll are detachably attached to the outer periphery of the die roll. I did.

[0008]

[Action]

 When mounting the die sheet in the mounting apparatus having the above structure, the die sheet is wound around the outer periphery of the die roll, and the band clamps are mounted around the outer periphery of both ends of the die sheet and tightened.

When the direction of the punching blade is corrected, each band clamp is loosened, the band clamp is moved in the circumferential direction of the die roll, and both ends of the die sheet are band clamped by the friction acting on the contact portion with the band clamp. Move in the same direction as.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the die roll 1 has roll shafts 2 at both ends, and the roll shaft 2 is rotatably supported by a pair of side frames 3.

A pair of band clamps 4 are attached to both ends of the outer periphery of the die roll 1. The band clamp 4 is provided with bending pieces 5a and 5b at both ends of an elastic band body 4a, and the bending pieces 5a and 5b are tightened by an operating screw 6 to reduce the diameter of the band body 4a.

Here, the band body 4a may be formed in a circular shape in advance with a diameter larger than the outer diameter of the die roll 1, or may be deformed into a circular shape when attached to the die roll 1. .

The die sheet attaching device shown in the embodiment has the above-described structure. When attaching the die sheet, the die sheet A is wrapped around the die roll 1 and the pair of band clamps 4 are attached to both ends of the die sheet A. After that, tighten each band clamp 4.

When correcting the inclination of the punching blade a of the die sheet A, each band clamp 4 is loosened, the band clamp 4 is moved in the circumferential direction of the die roll 1, and acts on the contact portion between the band clamp 4 and the die sheet A. Both ends of the die sheet A are moved in the same direction as the band clamp 4 by the frictional force.

[0016]

[Effect of device]

 As described above, in the die sheet attaching apparatus according to the present invention, the both ends of the die sheet wound around the outer periphery of the die roll are clamped by the pair of band clamps, so that the die sheet can be easily attached and detached. It is possible to efficiently replace the die sheet in a short time, and the die sheet is not damaged when the die sheet is removed.

When the pair of band clamps are loosened and the band clamps are moved in the circumferential direction of the die roll, both ends of the die sheet are moved in the circumferential direction by the frictional force acting on the contact portion with the band clamp. Therefore, it is easy to correct the inclination of the punching blade.
