Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube or label tape printer cutting device for cutting a tube or label tape on which characters such as the wiring destination of an electric wire are printed.

[0002]

2. Description of the Related Art In a conventional cutting device for a tube or a label tape printer, the cutter is a worn item, but the blade tip is in a bare state, and the portion that covers the blade tip is protected to protect the fingertip from cuts and the blade tip. There is a structure that can be expanded and contracted, and at the time of replacement, there were times when the fingertip touched the blade edge of the exposed cutter, causing a cut. Further, even in a cutter in which the portion covering the cutting edge is configured to be expandable and contractible, if the cutting edge portion is slightly strengthened, there is a risk of making a cut. Further, in a cutting device in which the blade edge of the cutter directly abuts against the blade holder, an excessive force may be applied to the blade edge, resulting in significant wear of the blade.

[0003]

DISCLOSURE OF THE INVENTION In a cutting device for a printer for a tube or a label tape, protection of a worker's fingertip when replacing a cutter, which is a worn product, protection of a blade of the cutter and reduction of wear of the cutter at the time of cutting. To solve the problem.

[0004]

In a cutting device for a tube or label tape printer, a cutter positioned inside the outer shape of a cutter holder on which an elastic cutter support arm is formed, and a cutter receiver provided on the cutter receiver holder. And a slider and a slider holder in which a back surface receiving shaft of the cutter that engages with the back surface of the cutter that respectively supports the cutter holder and the cutter receiving holder is provided.
Further, the cutter holder that supports the cutter and the cutter holder that supports the cutter holder are configured to be freely inserted into and removed from the slider and the slider holder, and the elastic body is provided on the back surface of the cutter holder.

[0005]

When the cutter holder supporting the cutter is inserted into the slider, the rear surface of the cutter engages with the rear bearing shaft of the cutter provided on the slider to project from the cutter holder, and when the slider slides in the cutter receiving direction together with the slider. , The tube or label tape located on the cutter and the cutter holder is cut. When an excessive force is applied to the cutting edge, the elasticity of the elastic body provided on the back surface of the cutter holder causes the cutter holder to move in the elastic body direction together with the cutter holder.

[0006]

Embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a cutter. The cutter 1 has a groove 1c and a chamfer 1d formed on a back surface 1b of a cutting edge 1a, and a hole 1e provided at a central portion. However, there is no problem even if the groove 1c is not formed. Reference numeral 2 is a cutter holder, and a cutter supporting arm 2a having elasticity is formed in the cutter holder 2, and the cutter supporting arm 2a further has a projection 2b pivotally attached to the hole 1e.
Besides, the knob 2c and the guide portion 2d are formed. FIG. 1 shows that the cutter 1 is supported by the cutter holder 2, and the hole 1e of the cutter 1 is pivotally attached to the projection 2b of the cutter support arm 2a through the elasticity of the cutter support arm 2a. In addition, the cutter 1 is provided with a plurality of holes 1d,
The cutter support arm 2a may be provided with a plurality of protrusions 2b at positions matching the holes 1d.

Reference numeral 3 is a slider, and a substantially rectangular notch 3a is formed in the slider 3, and a guide 3b pivotally attached to the guide portion 2d of the cutter holder 2 is provided in the notch 3a, and a circular shape is provided downward. Hole 3c is formed, and a hole 3e connected to the V groove 3d is provided at one end. Reference numeral 4 denotes a back surface receiving shaft of the cutter, and the back surface receiving shaft 4 is press-fitted into the side surface of the slider toward the rectangular notch 3a.
Since the slider 3 is configured in this way, when the guide portion 2d of the cutter holder 2 is inserted into the rectangular notch 3a along the guide 3b, the cutter 1 engages with the back receiving shaft 4 of the cutter, It projects from the cutter holder 2 against the elasticity of the cutter support arm 2a. Further, when the groove 1c is formed in the cutter 1, when the groove 1c is engaged with the back surface receiving shaft 4 of the cutter and positioned,
Clicking on due to the elasticity of the cutter support arm 2a,
It can be seen that the cutter 1 and the cutter holder 2 are properly positioned with respect to the slider 3. Reference numeral 5 is a roller, and the roller 5 is provided in a hole 3e which is continuous with the V groove 3d.

Reference numeral 6 denotes a slider holder, and a shaft 7 on which the slider 3 slides is provided below the slider holder 6, and a spring 8 is attached to the shaft 7.
Is inserted, an elastic body 9 is attached to the upper groove, and is fixed to the base plate 10 with a screw 11. Reference numeral 12 denotes a cutter receiving holder. The cutter receiving holder 12 is formed of a flexible material, has a groove 12a, a hook portion 12b, a knob 12c, and is provided with a metallic cutter receiving 12d. A pair of stoppers 12e are provided so as to project and can be inserted into and removed from the slider holder 6.

A cam portion 13a and a cam gear 13b are integrally formed on the cam portion 13. The cam portion 13a engages with the roller 5 and is rotatable about a base plate 10 by a shaft 14. It is provided. A stepping motor 15 is fixed to the base plate 10, and a motor gear 16 is fixed to its shaft 15a.

With such a configuration, as shown in FIGS. 8 to 9, the label tape 17 with separator paper is provided between the cutter holder 12 provided with the cutter holder 12d and the cutter holder 2 provided with the cutter 1. When positioned, the slider 3 moves in the cutter receiving direction via the motor gear 16, the cam gear 13b, the cam portion 13a, the roller 5 and the like by the rotation of the motor 15, and is attached to the cutter 1 and the slider holder 6 attached to the slider 3. The label tape 17 is cut by the cutter receiver 12d. However, in this figure, only the label tape is cut, the separator is not cut, and the blade is stopping against the stopper 12e. However, if the stopper 12e is removed or avoided, the label tape and Can be cut along with the release paper.

Further, even if the tube 18 is located between the cutter holder 12d and the cutter 1 as shown in FIG. 10, the cutter holder 1 mounted on the slider 3 and the cutter holder 12d mounted on the slider holder 6 similarly perform the operation. The label tape 17 is cut or half-cut.

[0012]

In the tube or label tape printer cutting device, the cutter is positioned inside the outer shape of the cutter holder on which the elastic cutter support arm is formed. It is possible to protect a person's fingertip from cuts and protect the blade edge of a cutter. Further, since the elastic body is provided on the back surface of the cutter receiving holder, it is possible to reduce the wear of the cutter even when an excessive force is applied to the cutting edge. Further, in this configuration, the elastic body on the back side of the cutter holder is stretchable when the half tape of the label tape with the release paper is cut and the release paper is not cut and the half cut of the tube is performed. From the average, the force is received and the parallelism between the cutter and the cutter receiver is maintained, so that the accuracy of the half-cutting device can be complemented and the half-cutting can be accurately performed.
