Abstract

PURPOSE:To facilitate the separation of a separator from a tape-type printed matter, on the rear side of which adhesive agent is arranged, by a method wherein the title mechanism is provided with an edge, cutting only the adhesive agent and the printed matter, and another edge, provided at a place apart from former edge with a predetermined distance in parallel to the former edge substantially and cutting the adhesive agent, the printed matter and the separator. CONSTITUTION:A tape 4 is cut by an edge 1 having a cutting blade longer than the thickness of the tape 4. The surface of the tape 4 except a separator 4c is cut by another edge 2 having a cutting unit 2a, whose length is the total thickness of a polyester film 4a, processed with sand mat, and adhesive agent 4b or 0.05-0.1mm, for example. The edge 2 is provided with the cutting unit 2a and a guide 2b, provided at a place with a predetermined distance from the tip end of the cutting unit 2a, so that the cutting unit 2b will never bite into the tape 4 any more. The predetermined distance is the total thickness of the film 4a and the adhesive agent 4 or 0.05-0.1mm, for example. The film 4a and the adhesive agent 4b, which are positioned at the left end of the tape 4, discharged out of an opening unit 7 and printed already, are cut while the separator 4c is not cut. The adhesive agent 4b and the separator 4c are peeled as shown by an arrow sign C in a diagram by applying a force shown by the arrow sign B in the diagram.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cutting mechanism of a printing device that prints characters, images, etc. on a tape-shaped printing material having an adhesive and a separator on the back side.

[Prior Art] The cutting mechanism of a conventional printing device that prints characters, images, etc. on a tape-shaped substrate with an adhesive and a separator on the back side uses a single blade to perform sliding cutting, push-cutting, or 2
A method such as scissor cutting using two blades was used.

[Problems to be Solved by the Invention] In the conventional cutting method, an image of the letters O#J, etc. is stamped, cut into a predetermined length, and discharged. It took some skill to remove the separator from the printed matter, and in the worst case, the printed matter was ruined. In addition, it is easy to peel off (if necessary, special and expensive adhesives and separators must be used, which is one of the reasons for the high price of the printing material as a consumable item).

In view of these problems, an object of the present invention is to provide a cutting mechanism that uses an extremely simple mechanism to easily peel off a separator from an inexpensive tape-shaped printing material with an adhesive and a separator on the back side. I will provide a.

[Means for Solving the Problems] In order to solve the above problems, a tape cutting mechanism of a printer according to the present invention is a tape cutting mechanism of a printer that prints on a tape-shaped substrate having an adhesive and a separator on the back side. After the printed material is discharged from the print head section, a blade that cuts only the adhesive and the printed material is placed approximately parallel to the blade at a predetermined distance, and the adhesive is and a blade for cutting the printing material and the separator.

[Embodiments] Examples of the present invention will be described below with reference to the drawings. FIG. 1 shows a printing device that is equipped with an adhesive tape cutting mechanism with a separator according to an embodiment of the present invention and prints characters, images, etc. on a tape-shaped printing material with an adhesive and a separator on the back side.

The separator-equipped adhesive tape cutting mechanism of the present invention is composed of a separator-equipped adhesive tape cutting blade 1, an adhesive tape-only cutting blade 2, a stand 11 for growing a groove 10 in which the blade l moves, and cases 12a and 12b. The tube is packed in the printing device consisting of. The cutting mechanism of the present invention is tube-packed,
The operation of the printing device will be explained below. The separator-attached adhesive tape 4 is manually pulled out in the direction of arrow A from the opening 7 of the main case. At this point, the blades 1 and 2 are located out of the running path of the tape 4. By moving the tape 4 between the driving roller 9c and the roller 9d, the driving roller 9
c rotates, and a timing pulse corresponding to the amount of movement of the tape 4 is generated by an encoder (not shown). In response to the timing pulse, data of necessary image information in characters is transferred to the thermal head 5, and necessary characters/images are printed on the tape 4 via the ink ribbon 3.

Next, the cutting mechanism will be explained with reference to FIG.

After printing is completed, the end of the printed portion of the tape 4 is moved to a position closer to the opening 7 than the blade I by manual operation. Then, place the blade 1 and the blade 2 from the back to the front on the drawing.
That is, the tapes 4 are simultaneously slid in a direction perpendicular to the longitudinal direction thereof. The tape 4 is cut by the blade 1 having a blade longer than the thickness of the tape 4, and the surface of the tape 4 is sandmatted to form a polyester film 4a.
and the total thickness of the adhesive 4b, which in this example is 0. 05+a
The blade 2 having the cut portion 2a having a fin length of +++ to 0.1 fins cuts everything other than the separator 4c. The blade 2 is cut at a certain distance from the cutting part 2a and the tip of the cutting part 2a, that is, the total thickness of the film 4a and the adhesive 4b, which is 0.05+=- to 0.1 mm in this embodiment. In place,
A guide 2b is provided to prevent the cut portion 2a from digging into the tape 4 any further. The guide 2b is molded integrally with the cut portion 2a, or is made separately from the cut portion 2a, and the cut portion 2a is fixed to the guide 2b by screws or the like. The blade 1
and the blade 2 are disposed between the drive roller 9c and the opening 7, the blade 1 being closer to the opening 7 than the blade 2, and the blade 1 being closer to the opening 7 than the blade 2.
The distance between the blade 20 and the blade 20 is a length that is easy for a person to pick with their fingers, that is, 6
Approximately 10 m to 10 m is appropriate.

After cutting, the blade 1 and the blade 2 are returned to their original positions, and the printed tape 4 is discharged from the opening 7 by rotating a knob 8 located outside the case 12b. At the same time, the tip of the unprinted tape 4 is exposed through the opening 7. 9a, 9b-9f-9g in FIG. 1 stabilize the running of the tape 4 and the ribbon 3, and 6 indicates hardness 6.
It is a platen made of rubber such as NBR of 0°.

As shown in FIG. 3(b), at the left end of the printed tape 4 discharged from the opening 7, the film 4a and the adhesive 4b are cut, but the separator 4c is not cut. By applying force B in Figure 3(b), the third
As shown in Figure (a), the adhesive 4b and the separator 4c are peeled off as shown in C.

In this embodiment, the drive roller 9c, the knob 8, etc. are driven by manual operation of the tape 4, but by connecting a stepping motor or a DC motor to the knob 8,
Automatic operation is also possible. The operation of the blade 1 and the blade 2 can be either manual or automatic. In addition to the thermal head 5, an impact dot head or the like may be used as the printing section. It is also possible to use other resin-based films, paper, etc. instead of the polyester film 4a.

[Effects of the Invention] As explained above, according to the configuration of the present invention, in a tape-shaped printing material having an adhesive and a separator on the back side, when cutting the tape after printing is completed using a tape printing device, ,
It has the effect of being easy to peel off when the separator is peeled off from a tape-shaped printing material with an adhesive on the back side.
