Abstract

PROBLEM TO BE SOLVED: To carry out full-cut and half-cut for a laminating member formed of a first layer and a second layer by a cutter blade and a cutting mechanism used in common. SOLUTION: When a tape 14 formed of a printing tape layer 14a as the first layer and a release layer 14c as a second layer is cut, a cutter supporting member 31 supporting the cutter blade 32 is moved in the first direction or the second direction in compliance with the rotating direction of a cutter driving motor 39. When the cutter supporting section 31 is moved in the first direction, protruded sections 33a and 33b of the cutter supporting member 31 are stored in recesses 35a and 35b formed on a supporting stand 34 and the cutting edge of the cutter blade 32 is brought into contact with the supporting stand 34 to cut the tape 14 (full-cut). When the cutter supporting member 31 is moved in the second direction, the protruded sections 33a and 33b of the cutter supporting member 31 are brought into contact with the supporting stand 34, and a space equivalent to the thickness of the release layer 14c is formed between the cutting edge of the cutter blade 32 and the supporting stand 34 to cut a printing tape 14a and a bonding agent 14b while leaving the release layer 14c of the tape 14 (half-cut).

The protrusion T of the protrusions 33a and 33b with respect to the cutter blade 32 is smaller than the depth of the recesses 35a and 35b formed in the receiving base 34.

In the initial state before the tape cutting mechanism 21 shown in FIG. 5 cuts the tape, the first and second cams 43a, 43
The engagement pins 44a and 44b of FIG. 3b are located at the ends of the cutter supporting member 31 in the elongated holes 45a and 45b, which are remote from the receiving table 34, and the cutter supporting member 31 is located farthest from the receiving table 34. ing.

Here, a full cut realized by the tape cutting mechanism 21 will be described.

FIGS. 6A and 6B show the tape cutting mechanism 21.
It is a figure explaining operation | movement of full cut. The full cut completely cuts the tape. For example, the full cut cuts the print tape layer 14a, the adhesive 14b, and the release layer 14c of the laminated tape 14 in FIG.

When the cutter driving motor 39 is driven to rotate forward from the initial state shown in FIG. 5, the first and second cams 43a, 43
3b simultaneously rotates in the direction of arrow A, and accordingly, the engagement pins 44a and 44b also move on an arc trajectory in a circle indicated by a dashed line. Then, the engagement pins 44a, 44b and the long hole 45
a and 45b are engaged and urged in the direction of the cradle 34 by the spring 50, so that the cutter support member 31 supporting the cutter blade 32 moves downward in FIG. Move towards. When the cutter driving motor 39 is further driven to rotate forward, the cutter supporting member 31 moves upward in FIG. 6B according to the movement of the circular arc trajectory of the engaging pins 44a and 44b, and the laminated tape on the receiving table 34 moves upward. 14 is fully cut.
As a result, the cutting edge of the cutter blade 32 moves on an arc substantially in contact with the receiving table 34. FIG. 6B shows a state at the time of completion of the full cut. At this time, the protruding portions 33a and 33b of the cutter support member 31 are stored in concave portions 35a and 35b provided at both ends of the blade receiving member 57 of the receiving base 34.

When the full-cut processing is completed, the cutter driving motor 39 rotates in the reverse direction, and the cutter supporting member 31 returns to the initial position in FIG.

At the time of half cutting, the cutter driving motor 39 rotates reversely from the initial state shown in FIG.
a and 43b rotate in the direction of arrow B, and accordingly, the engagement pins 44a and 44b also move on an arcuate trajectory within a circle indicated by a dashed line. Then, the engagement pins 44a, 44b and the long hole 45
7a and 45b are engaged and urged in the direction of the cradle 34 by the spring 50, so that the cutter support member 31 supporting the cutter blade 32 moves upward in FIG. Move towards. Then, the protrusion 3 of the cutter support member 31
3a and 33b come into contact with the cradle. When the cutter driving motor 39 is further driven in the reverse direction, the cutter supporting member 31 is rotated.
Conversely, while moving downward in FIG. 7B, the cutting edge of the cutter blade 32 moves on an arc substantially in contact with the receiving table 34, and
With the print tape layer 14a facing the cutter blade 32, the release layer 1
4c, only the printing tape layer 14a portion of the laminated tape 14 arranged toward the receiving table 34 is cut.

In this case, the protrusion 3 of the cutter support member 31
The leading ends of 3a and 33b are closer to the release layer 1 than the leading end of the cutter blade 32.
4c, and a protrusion T is provided between the cradle 34 and the cutter blade 32.
The print tape layer 14a and the adhesive 14b are cut except for 4c. FIG. 7B shows a state at the end of the half cut.

When the half-cut processing is completed, the cutter driving motor 39 rotates forward and the cutter supporting member 31 returns to the initial position in FIG. The initial position of the half cut of the cutter blade 32 is the same as the initial position of the full cut, and the initial position and the end position of the half cut detect the rotation angles of the first and second cams 43a and 43b by the cutter sensor. It is done by doing.

FIG. 9 shows the state of the cutter blade 32 during the full cut, and FIG. 8 shows the state of the cutter blade 32 during the half cut.

Further, when the laminated tape 14 is cut by the cutter blade 32 by full cutting or half cutting by the movement of the cutter supporting member 31, the tape pressing member 51 shown in FIG. It moves toward the table 34 and presses the laminated tape 14 against the blade receiving member 57 of the table 34. By pressing the laminated tape 14 by the tape pressing member 51, the laminated tape 14 is cut at the time of cutting.
Can be prevented from moving and can be cut cleanly.
