Abstract

PROBLEM TO BE SOLVED: To provide a cutting device capable of cutting a part or all layers of a laminate member using a simple configuration and of certainly cutting only one layer of the laminate member. SOLUTION: The cutting device 10 is composed of a first and a second cutting mechanisms 11, 12 and a single cutter motor 13 and driving mechanism 14 for driving the cutting mechanisms. When the cutter motor 13 is rotated in the regular direction, the torque is transmitted to a cam 53 through the driving mechanism 14, and a moving blade 22 for full-cut moves toward a stationary blade 21 to cause all the laminate tape 6 to be cut. When the cutter motor 13 is rotated reversely, a moving blade 32 for half cut abuts to a receptacle table 31 through the action of the cam 53 under the drive of the motor 13 while a certain gap is reserved in between to cause a printing tape 6a to solely be cut. At this time, the cutter motor 13 is controlled so that abutting of the moving blade 32 to the receptacle table 31 is made for a specified period of time, which ensures a certain operation of cutting.

The cutting blade constituting the receiving and cutting mechanism is moved toward the receiving table. At this time, a gap corresponding to the thickness of the printing tape or the release tape of the laminated tape is formed in a state where the cutting blade is in contact with the receiving table, and only one of the gaps is cut. Here, by controlling the drive motor so that the cutting blade is kept in contact with the pedestal for a predetermined time, the blade edge of the cutting blade sufficiently penetrates into the tape layer to be cut and penetrates in the thickness direction. As a result, it is possible to reliably cut either the tape layer to be cut, either the printing tape or the release tape. Further, the torque limiter interposed in the transmission mechanism can protect the drive motor from applying a certain torque or more to the drive motor.

By mounting the cutting device having such a configuration on a printing device, only the printing tape of the laminated tape on which printing has been performed by the printing means of the printing device can be cut.

Next, the structure of the drive mechanism 14 will be described.

FIG. 6 is a perspective view showing the structure of the drive mechanism 14 of the cutting device 10, and FIG. 7 is an exploded perspective view showing the structure of the torque limiter portion of the drive mechanism 14.

As shown in FIG. 6, the driving mechanism 14 includes a transmission mechanism 51 for transmitting the rotational driving of the cutter motor 13 in both the forward and reverse directions, a torque limiter 52 inserted in the transmission mechanism 51, and a movable mechanism. And a cam 53 used as a blade moving mechanism.

And transmits the rotational drive of the cutter motor 13 in both the forward and reverse directions. This transmission mechanism 51 includes a torque limiter 5
2 is inserted. As shown in the exploded perspective view of FIG. 7, the torque limiter 52 includes gears 62 and 63 and a coil spring interposed therebetween. By providing the torque limiter 52, the idle rotation occurs between the gear 62 and the gear 63 when a certain load or more is applied on the load side (cutting mechanism side). The torque limiter is not limited to the one shown.

The cam 53 is provided at the last end of the gear train of the transmission mechanism 51, and has a projection 54 on its rotating surface. FIG.
As shown in FIG. 7, when the cam 53 is rotated by receiving the rotation of the cutter motor 13 in the forward direction, the projection 54 is formed on the operation projection 25 provided at the end of the arm 23 of the first cutting mechanism 11. To move the movable blade 22 for full cut to a position intersecting with the fixed blade 21. On the other hand, when the cam 53 rotates in response to the rotation of the cutter motor 13 in the reverse direction, the protrusion 54 is moved to the second cutting mechanism 12.
The movable pin 32 for half-cut is moved to a position where it comes into contact with the pedestal 31 by pressing the operating pin 35 provided at the end of the arm section 33 of FIG.

As shown in FIG. 3, a first sensor 71 and a second sensor 72 are installed on the chassis 2a of the apparatus main body 2 so as to face the side surface of the cam 53. The first sensor 71 and the second sensor 72 are composed of micro switches, and perform ON / OFF operations according to the rotation angle of the cam 53 at the time of full cut and half cut. The side surface of the cam 53 has an uneven shape for turning on / off the first sensor 71 and the second sensor 72 at a predetermined rotation angle.

Here, a full cut realized by the first cutting mechanism 11 will be described.

FIGS. 8A and 8B are views for explaining the full cutting operation by the first cutting mechanism 11. FIG. 8A shows the initial state, FIG. 8B shows the state during the full cutting, and FIG. Indicates a state where the full cut is completed. When the first cutting mechanism 11 is installed in the tape printer 1, the left side of those figures is at the top.

The full cut is to completely cut the tape. Here, it is assumed that the printing tape 6a, the release tape 6b, and the adhesive 6c of the laminated tape 6 shown in FIG. 2 are cut.

As shown in FIG. 8A, in the initial state,
The movable blade 22 is set at an initial position (home position) by a spring 26. At this time, the first sensor 71
Is ON, and the second sensor 72 is OFF.

When the cutter motor 13 is driven to rotate forward from the initial state, the cam 53 rotates counterclockwise as viewed in the figure, and accordingly, the projection 54 of the cam 53 also moves on the circular orbit of the cam 53. 23 abuts on the operation projection 25 at the end. As a result, the arm 23 is pushed by the projection 54 and moves toward the fixed blade 21 against the force of the spring 26. When the cutter motor 13 is further driven to rotate forward, the movable blade 22 and the fixed blade 21 intersect, and the laminated tape 6
Is fully cut.

FIG. 8B shows a state in which a full cut is being performed. At this time, the first sensor 71 and the second sensor 7
2 are both OFF. FIG. 8C shows the end state of the full cut. At this time, the first sensor 71
Is OFF, and the second sensor 72 is ON. When the cutter motor 13 rotates in the reverse direction after the full cut, the movable blade 22
Is returned to the initial position in FIG.

FIGS. 9A and 9B are views for explaining the half-cutting operation by the second cutting mechanism 12. FIG. 9A shows the initial state, and FIG. 9B shows the half-cutting state and the end state. . When the second cutting mechanism 12 is incorporated in the tape printer 1, the left side of the drawings is at the top.

As shown in FIG. 9A, in the initial state,
The movable blade 32 is located at the same position as the first cutting mechanism 11.
Is the initial position (home position) by the force of the spring 37
Is set to At this time, the first sensor 71
N, the second sensor 72 is OFF.

When the cutter motor 13 is driven to rotate in the reverse direction from the initial state, the cam 53 rotates clockwise as viewed in FIG.
Accordingly, the projection 54 of the cam 53 also moves on the circular orbit of the cam 53 and comes into contact with the operating pin 35 at the end of the arm 33. As a result, the arm 33 is pushed by the projection 54 and moves toward the receiving table 31 against the force of the spring 37. When the cutter motor 13 is further driven in the reverse direction, the protrusions 47 and 48 of the cutter holder 41 come into contact with the receiving table 31. In this case, the tips of the projections 47 and 48 protrude from the cutting edge of the movable blade 32 by a dimension of T corresponding to the thickness of the peeling tape 6b, and a T gap is formed between the receiving table 31 and the movable blade 32. Therefore, only the printing tape 6a and the adhesive 6c are cut while leaving the release tape 6b. FIG. 9B shows a state in which half cutting is being performed. At this time, both the first sensor 71 and the second sensor 72 are turned ON.

In order to sufficiently press the blade edge of the movable blade 32 against the laminated tape 6, the cutter motor 13 is further driven in the reverse direction in the state shown in FIG. 9B. At this time, a torque limiter 52 is interposed in a transmission mechanism 51 for transmitting the rotational drive of the cutter motor 13 in order to prevent a torque greater than a certain value from being applied to the cutter motor 13 (see FIGS. 6 and 7). When the cutter motor 13 is driven to rotate in the reverse direction for n seconds, the half-cut on the laminated tape 6 ends. At the end of the half cut, the state is the same as that in FIG. 9B. After the half-cut is completed, the cutter motor 13 rotates forward, and the movable blade 22 returns to the initial position in FIG.

Then, only the printing tape 6a of the laminated tape 6 is cut.

In this case, the reverse rotation drive of the cutter motor 13 is set for n seconds. The n seconds are set to be longer than the time until the protrusions 47 and 48 of the cutter holder 41 come into contact with the receiving table 31. Therefore, after the protrusions 47 and 48 of the cutter holder 41 abut on the pedestal 31,
The movable blade 32 is pressed against the printing tape 6a of the laminated tape 6 for the remaining time of n seconds. As a result, cutting can be surely performed, and a half cut can be cut neatly. At that time, the cutter motor 1
A torque limiter 52 is interposed in a transmission mechanism 51 for transmitting the rotational drive of the cutter motor 13 in order to prevent a predetermined torque or more from being applied to the motor 3.

By the drive of No. 1, a full cut process is performed on the laminated tape 6 (step A13). As a result, as shown in FIG. 12, the printed laminated tape 6 is completely cut off and discharged out of the apparatus from the paper discharge port 7, and a margin a is formed after the character string of the laminated tape 6.

At the time of the full cut, as shown in FIG. 14C, the cutter motor 13 is driven to rotate forward (step C1). By the forward rotation of the cutter motor 13, as described with reference to FIG. 8, the full-cut movable blade 22 constituting the first cutting mechanism 11 moves from the initial position toward the fixed blade 21. When the cutter motor 13 is driven to rotate forward until the first sensor 71 is turned off and the second sensor 72 is turned on (step C2), the movable blade 22 and the fixed blade 21 are driven.
Intersect with each other, the entire laminated tape 6 is cut, and the printed tape portion is cut off as a label.

After the end of the full cut, the first sensor 71
N, the cutter motor 13 is driven to rotate forward until the second sensor 72 is turned off (steps C3 and C4). As a result, the movable blade 22 returns to the original initial position.

In the label created by such a printing process, a notch is formed at the end of the printing tape 6a of the laminated tape 6 by the half-cut process, so that the printing tape 6a is easily peeled off from the peeling tape 6b. Can be
For example, it can be used as a sticky note.

I do. In this case, since the driving of the cutter motor 13 is controlled so as to hold the movable blade 32 on the receiving table 31 for a predetermined time, a part of the layer of the laminated tape 6 can be reliably cut. Further, at this time, even if a certain amount of torque is applied to the cutter motor 13, the cutter motor 13 is caused to idle by the torque limiter 52 inserted in the transmission mechanism 51.
3 is not damaged.

The torque limiter 52 need not always be provided. In that case, the cutter motor 1
Third, it is desirable to use a lock motor capable of coping with the locking of the output shaft.

Further, in the above-described embodiment, the description has been made on the assumption that the laminated tape for printing used in the printing apparatus is cut. However, the present invention is not limited to the laminated tape used in the printing apparatus, but may be used for the first layer. The present invention is applicable to all laminated members formed by laminating the second layer.

In the above embodiment, the laminated tape having the first layer as the printing tape and the second layer as the release tape was used. However, the reverse structure, that is, the first layer as the release tape and the second layer as the release tape, was used.
You may use the laminated tape which made the layer a printing tape.
