In the above-described cutter mechanism, the blade base moved by the driving of the motor must reach the cutting end position (standby position) within a predetermined time during which the motor is rotating. No. If the time for driving the motor is the time required for the blade base to move, the blade base may not reach the cutting end position (standby position). Therefore, it is necessary to set the time for driving the motor to be the time obtained by adding the time required for the movement of the blade base to the time required for the margin. Actually, the time for the margin is about 0.3 to 0.5 seconds.

For this reason, the motor is locked by the gripping force of the wire and the pulley for about 0.3 to 0.5 seconds after the blade base collides with the stopper. The coating is deteriorated or deformed, and eventually the coating is peeled off and the grip is lost. If the grip is lost, the blade base cannot be transported, and the life of the cutter will be extended.

Although the grip of the wire and the pulley gradually deteriorates with aging, if the motor is locked by the grip of the wire and the pulley for the margin time as described above, the deterioration speed of the grip is high, and the durability is high. Performance is inferior.

Accordingly, an object of the present invention is to provide a cutter mechanism for maximizing the deterioration of the wire by obtaining a configuration in which the motor is locked regardless of the grip between the wire and the pulley.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment according to the present invention will be described below with reference to the drawings.

FIG. 1 shows the best mode of the present invention. A long linear fixed blade 2 is attached to the lower surface of a plate-like frame 1 extending in the longitudinal direction and fixed by welding or the like so as to be parallel to the longitudinal direction of the frame 1. . Further, the sliding rail 3 is formed above the fixed blade 2 by bending one end of the frame 1 into a key shape.

Since the frame is usually attached to various devices having a cutter mechanism, a small space is required. However, there is no need to extend the shape of the frame in the longitudinal direction if there is no space restriction.

A slide table 4 having a concave holding portion is fitted into the slide rail 3, and the fixed blade 2 is moved along the slide rail 3.
The sliding reciprocating motion is possible in the longitudinal direction of the. In addition,
The slide table 4 is connected to the blade table 5 by a connecting arm 7, and the blade table 5 operates integrally with the slide table 4. There is no problem if the blade base 5 and the slide base 4 are integrated.

A pulley 8 is disposed on the frame 1 at each end of the fixed blade 2 in the longitudinal direction. One pulley 8 (in the longitudinal direction in FIG. 1) is provided with a drive shaft of a motor 11. Pinion 10 and gear 9 provided in
It is attached so as to obtain a rotational force via the. The gear 9 may be provided on the pulley 8 itself or may be fixed so as to rotate integrally with the pulley 8. The pulley 8 is supported on the frame 1 by a pulley support shaft 12, and the pulley support shaft 12 stops the reciprocating motion of the blade base 5 by collision.
Also serves as 3.

In this embodiment, the stopper 13 is also used as the pulley support shaft 12. However, as long as the reciprocating motion of the blade base can be stopped by collision, the stopper can be moved to another place such as a frame or a fixed blade. However, there is no problem with any shape.

A tension wire 14 is laid between the pulleys 8 with a biasing means such as a coil spring interposed therebetween. The wire 14 is engaged with a predetermined position of the slide table 4.

When the motor 11 is driven, the motor 1
The pinion 10 attached to the output shaft 1 transmits a rotational force to the pulley 8 via the gear 9, and when the pulley 8 rotates, the wire 14 reciprocates the slide table 4 along the slide rail 3. Let it. It should be noted that the blade base 5 reciprocates in the same manner as the slide base 4 moves.

On the other hand, a round blade 6 is rotatably supported on the blade base 5 by a support shaft and a bearing, and the blade edge of the round blade 6 is disposed so as to slightly overlap the blade edge of the fixed blade 2. In addition,
The round blade 6 and the bearing rotate integrally.

A wheel (not shown) that rotates integrally is attached to the round blade 6, and the edge of the wheel is pressed against the fixed blade 2, and when the slide 4 moves, the wheel rotates. At the same time, the round blade 6 also rotates.

The blade base 5 has an introduction guide section 15 for urging the fixed blade 2 to urge the sheet to be cut immediately before cutting the sheet to be cut with this movement, and a contact point between the round blade 6 and the fixed blade 2. A guide guide 16 for guiding the sheet to be cut to the sheet (hereinafter referred to as a "sheet cutting point") and a guide 17 for retracting the cut piece from the connecting arm 7 as needed during sheet cutting are provided.

Further, in the cutter mechanism of the present invention, a rack is provided on the slide 4 so as to mesh with the gear 9 of the pulley 8 on the motor 11 side.

When the rack and the gear 9 mesh with each other, the gear may be broken if the gear is meshed, and the gear cannot be avoided by a normal gear design. Therefore, the gear 9 is displaced to the side receiving the load at the time of meshing.

In this case, since the rack is on the moving side and the collision is caused on the gear 9 side of the pulley 8, this is displaced.

According to experimental results, the amount of dislocation must be at least 0.5 in the negative direction, and is most preferably set to 1 in the negative direction including the margin.

Table 1 shows the experimental results.

Next, the operation of the first embodiment according to the present invention will be described with reference to FIGS.

When the motor 11 is driven, the pinion 1
0, when a rotational force is transmitted to the pulley 8 via the gear 9, a traction force is applied to the wire 14, and the slide table 4 and the blade stand 5 waiting at the standby position move along the slide rail 3. Moving.

The cutting edge of the round blade 6 pivotally supported by the support shaft of the blade base 5 slightly overlaps with the cutting edge of the fixed blade 2 and is pressed against a predetermined pressure by a leaf spring. By doing so, the sheet placed between the fixed blade 2 and the round blade 6 is cut.

The wheel and the round blade 6 move while rotating together with the movement of the blade base 5, and the wheel is pressed against the fixed blade 2 via the sheet during the cutting of the sheet. There is no.

At the start of cutting the sheet, the end of the sheet is urged to the fixed blade 2 by the introduction guide section 15 provided on the blade base 5, and the sheet is guided to the cutting point by the guide section 16. The cutting sheet is retreated at any time by the introduction guide section 17 provided in the section.

Since the cutter mechanism of the present invention is not provided with a sensor for detecting the position of the blade base 5, the blade base 5 is forcibly stopped when the blade base 5 collides with the stopper 13.

As shown in FIG. 8, the operation of the cutter mechanism is controlled by rotating the motor 11 forward for T1 for the cutting operation and reversely rotating the motor 11 for T2 for the retreat operation in accordance with the cutting instruction signal, as shown in FIG. Here, T1 is a time obtained by adding a time required for the cutting operation by the blade base 5 to the margin, and T2 is a time obtained by adding a time required for the cutting operation to the blade base 5 to the evacuation operation by the margin. .

When a signal for rotating the motor 11 in the normal direction is sent to the drive circuit by the above control, the blade base 5 at the standby position moves while moving the cutting blade set between the fixed blade 2 and the round blade 6. Cut the sheet. Thereafter, when the blade base 5 collides with the stopper 13 at the cutting end position, the movement of the blade base 5 stops. At this time, since the predetermined time T1 is longer than the required time required for the movement of the blade base 5, after the blade base 5 collides with the stopper 13, the motor 11 Stops.

Next, a signal for rotating the motor 11 in the reverse direction is sent to the drive circuit, and the blade base 5 at the cutting end position moves to the standby position side for a predetermined time T2 and collides with the stopper 13 at the standby position. The movement of the blade base 5 stops. At this time, since the predetermined time T2 is longer than the required time required for the movement of the blade base 5, after the blade base 5 collides with the stopper 13, the motor 11 waits for a time corresponding to the difference between T2 and the required time. Stops.

At this time, the rack 18 provided on the slide table 4
Meshes with the gear 9 provided on the pulley 8, so that the rotation of the gear 9 stops as the slide table 4 stops.

Therefore, the motor 11 is driven for a margin time of the predetermined time T2 during which the motor 11 is driven, that is, during the period from when the slide 4 stops to when the drive of the motor 11 stops.
Is locked not by the grip of the pulley 8 and the wire 14, but by the engagement of the rack 18 and the gear 9. Therefore, the load on the wire 14 is eliminated, and the deterioration of the grip can be suppressed.

Thereafter, when a predetermined time T2 elapses, the motor 1
1 is stopped, and the slide table 4 and the blade table 5 wait for the next cutting.

Incidentally, when the present embodiment was actually manufactured and tested, the deterioration of the wire 14 was reduced by half compared to the conventional device, and as a result of the durability test, the life of the wire 14 was about three times as long.

The operation control of the cutter mechanism is performed by the first control described above.
In the same manner as in the embodiment of the present invention, the cutting and retreat are performed by rotating the motor 29 forward for T1 time and then rotating the motor 29 for T2 time.

Here, when the retreat operation is completed, the blade rest 24
Collides with the stopper 31 and stops. At the same time, the gear 2 of the rack 32 and the pulley 26
7 engages and a means for locking the motor 29 between the pulley 26 and the wire 30 corresponds to a margin time of a predetermined time T2 during which the motor 29 is driven, that is, from when the blade base 24 stops until the drive of the motor 29 stops. Since it is not the grip but the engagement of the rack 32 and the gear 27, the load on the wire 30 is eliminated, and the deterioration of the grip can be suppressed.

Next, a third embodiment of the present invention will be described with reference to FIG.
