128, a sheet key interface 129, and a movement mechanism interface 130, which are mutually connected by a bus line 132 including a data bus, a control bus, and the like.

The cutting device according to the present embodiment is basically configured as described above, and its operation and effect will be described next.

First, information of desired marks A, B, and C is written on the floppy disk 134 by an FDD (not shown). on the other hand,
In the cutting device 10, the power is turned on and the placement plate 24
Place the fabric 136 to be cut on top. In this case, as the cloth 136, a piece of cloth provided with a laminated adhesive on the back side, or a cloth for mark and a base cloth are polymerized and laminated on the surface of the base cloth on the side of the object to be pressure-bonded. It is possible to use the one provided with the adhesive.

Therefore, when the floppy disk 134 is inserted into the insertion opening 16 formed in the mounting table 12, the mark information written on the floppy disk 134 is taken into the RAM 126. Therefore, by operating the sheet key 18,
The cutting device 10 is driven and controlled by a system program or the like recorded in the RAM 126 and the ROM 124.

In other words, place the heat cutter 100 in the original position in advance on the cloth 1
The rotary drive sources 46 and 76 are driven to transfer to the cutting start position of 36. When the rotary drive shaft 46a is rotated in a predetermined direction under the driving action of the rotary drive source 46, the pulley 48 pivotally mounted on the rotary drive shaft 46a is rotated, and the groove stretched between the pulley 48 and the roller 52 is extended. The first moving body 56 is indicated by the arrow X via the attached belt 50.
Move in the direction. On the other hand, when the pulley 78 is rotated in a predetermined direction via the rotary drive shaft 76a under the driving action of the rotary drive source 76, similarly, the grooved belt 82 stretched between the pulley 78 and the guide roller 62 causes 2 The moving body 84 moves in the arrow Y direction. Therefore, the heat cutter 100 moves substantially in the biaxial directions of the orthogonal coordinate system to reach the cutting start site of the cloth 136. At that time, the drive of the respective rotary drive sources 46 and 76 is stopped.

Then, the linear solenoid 64 constituting the displacement means 63 is driven to displace the rod 64a in the vertically downward direction against the tensile force of the tension spring 70. As a result, the swinging member 66 engaged with the rod 64a is swingably displaced vertically downward, and the support rod 7 held by the swinging member 66 and the guide bar 58a.

Is held above the fabric 136 (see FIG. 7b). Therefore, as described above, when the support rod 72 swings vertically downward, the arm member 94 swings vertically downward under its own weight and the tension action of the tension springs 96a and 96b.
The tip portion 106 of the heat cutter 100 engages the fabric 136 (see Figure 7c). As a result, the tip portion 106, which has been heated to a predetermined temperature, heat-cuts the cutting start portion of the cloth 136.

Therefore, the rotation driving sources 46 and 76 are driven and controlled under the driving action of the control unit 120, and the tip unit 106 of the heat cutter 100 is two-dimensionally moved along a desired locus to obtain the desired marks A and B. And the thermal cutting work of C is performed (see FIG. 8). Here, when the tip portion 106 reaches the non-melting portion, the swinging member 66 is swingably displaced vertically upward under the tensioning action of the tension spring 70 by deactivating the linear solenoid 64,
The support rod 72 integrally bridging the swinging member 66 and the mounting member 74 is moved vertically upward. Therefore, the support rod 72 swings the arm member 94 in the vertically upward direction, and the tip portion 106 of the heat cutter 100 held by the arm member 94 via the gripping portion 98 is separated from the cloth 136. .

After the desired marks A, B, and C have been heat-melted in this way, the rotary drive sources 46 and 76 are driven while the tip portion 106 of the heat cutter 100 is separated from the cloth 136 to drive the heat cutter 100. Is moved to the cleaning means 26 side. Further, when the rotary drive source 76 is driven to move the second moving means 83 to the cleaning means 26 side along the arrow Y direction, the tip portion 106 comes into the slit groove 34 of the spongy body 32 to wash water. The tip portion 106 is washed by the sponge body 32 including the. Next, the rotary drive source 76 is driven to drive the second moving body.
84 is displaced in the direction of separating from the housing 14 along the arrow Y direction to separate the tip portion 106 from the spongy body 32, and
The heat cutter 100 is moved to a predetermined original position.

On the other hand, the cloth 13 cut with the desired marks A, B and C
6 is removed from the arrangement plate 24, and a new cloth 136 is placed on the arrangement plate 24. At this time, the cloth 136 may be attached to the arrangement plate 24 by an adhesive provided on the back surface of the cloth 136. At this time, the operator's finger is inserted into the opening 22, the placement plate 24 is removed from the mounting table 12 integrally with the cloth 136 after the cutting work, and the recess 20 of the mounting table 12 is removed.
A new placement board 24 is placed on the new placement board 24, and a new cloth 136 is placed on the new placement board 24. Then, when the desired cutting operation is performed on this new cloth 136, as described above, the operation of removing this cloth 136 from the arrangement plate 24 to which the cloth 136 after cutting is attached is performed.

In this case, according to the present embodiment, the first movable body 56 that is displaceable in the arrow X direction along the guide rail 54 is provided under the driving action of the rotary drive source 46, and the first movable body 56 and the movement auxiliary body are provided. 60
A second moving body 84, which is displaceable in the direction of the arrow Y, is disposed under the driving action of the rotary driving source 76 along the guide bars 58a and 58b that are bridged with the cutting bar. As a heat cutter 100 is attached. For this reason,
The heat cutter 100 is a cloth 1 placed on the placement plate 24.
It is possible to move freely in the two axis directions of the Cartesian coordinate system with respect to 36, and it is possible to accurately move the tip portion 106 of the heat cutter 100 along a desired locus of marks A, B, C, and the like. Become. As a result, the marks A, B and C can be accurately cut into a predetermined shape and the automation of the mark cutting work can be easily achieved, as compared with the conventional case where the worker performs the mark cutting work. To be done. As a result, various marks can be efficiently cut in a large amount.

Moreover, in this embodiment, the first moving means 40 and the second moving means 83 are only linearly moved forward and backward in the directions of the arrows X and Y, respectively. Therefore, there is an advantage that the structure of the moving mechanism 38 is simplified, and the cutting device 10 can be downsized and the cost can be reduced.

Furthermore, the arm member 94 that constitutes the cutting device 10 can be tilted by a predetermined angle from the vertically upward direction toward the guide bar 58b with the support shaft 92 as a fulcrum. Thus, for example, the fabric 136
When the marks A, B and C are removed after the cutting work of FIG. 7 is finished, the heat cutter 100 can be held with the tip portion 106 inclined upward as shown in FIG. 7A. It is preferable that the tip portion 106 does not interfere with the work of removing A, B and C. Furthermore, when the cord 108 is connected to a power source to preheat the heat cutter 100 to start the mark cutting work, if the same state is maintained, for example, the tip portion 106 is near the cloth 136. It is possible to prevent the inconvenience that the fabric 136 is unnecessarily heat-fused.

Furthermore, the cord 108 of the heat cutter 100 is held by a flexible cord support 110 provided in the housing 14. For this reason, the heat cutter 100 moves the arrows X and Y.
When moving in the direction, the cord support 110 flexes freely while holding the cord 108 (see FIG. 8). Therefore, it is not necessary to greatly loosen the cord 108 between the second moving body 84 and the cord supporting body 110, and the cord 108 performs a very smooth mark cutting operation without interfering with the movement of the heat cutter 100. The effect that it becomes possible is obtained.

[Effects of the Invention] As described above, according to the present invention, it is possible to automatically and accurately cut a mark such as a desired character or number from a cloth or the like, and for cleaning work of the thermal disconnector. There is an advantage that the efficiency of the entire mark cutting operation is achieved without interrupting the mark cutting operation. In addition, the mechanism for moving the heat blower two-dimensionally with respect to the cloth or the like is simplified at a stroke, and the cutting device can be easily miniaturized and manufactured economically.

Although the present invention has been described with reference to the preferred embodiment, the present invention is not limited to this embodiment,
It goes without saying that various improvements and design changes can be made without departing from the scope of the present invention.
