Instead of the 96b, a leaf spring, a cylinder or the like can be adopted. Furthermore, it is also possible to directly cover the pressing plate 99 with a cutting means described later.

A heat cutter (heat fusing device) 100 as a cutting means is mounted on the grip 98. As shown in FIG. 4, the heat cutter 100 has a main body 102 held by a gripper 98, and a rod-shaped heater (substantially,
A ceramic heater 106 is accommodated. A tip portion 108 for thermally fusing a fabric (described later) is attached to the holder portion 104 in the vicinity of the tip of the heater 106. This tip portion 108 is formed of a copper material,
A chrome plating process is applied to the tip as a reinforcing means 110. As the reinforcing means 110, for example, a needle-like body formed of ruby or diamond can be used, and this needle-like body can be fixed to the tip of the tip portion 108. Also, the entire tip portion 108 is formed of ceramics. You may.

The heater 106 is connected to a power source (not shown) via a cord 114 extending from the main body 102. A flexible support member 116 wound spirally is provided on a housing 14 of the cutting device 10 via a bearing 118 so as to be rotatable. The cord 114 is held by the support member 116. You.

The control unit 120 includes a CPU 122, a ROM 124 in which information such as an original position of the heat cutter 100 and a system program is input in advance, and a RAM 126 for capturing information corresponding to a mark shape described later.
, An FD interface 128, a sheet key interface 129, and a moving mechanism interface 130, which are interconnected by a bus line 132 including a data bus and a control bus.

Next, the cutting apparatus 10 thus configured
Will be described.

First, desired information of marks A, B, and C is written on the floppy disk 134 by an FDD (not shown). On the other hand, the power is turned on in the cutting device 10, the cloth 136 to be cut is placed on the arrangement plate 24, and the floppy disk 134 is inserted into the insertion slot 16 formed in the placing table 12. .
In this case, the cloth 136 may be a single cloth provided with an adhesive laminated on the back side, or a mark cloth and a base cloth may be superimposed and laminated on the surface of the base cloth on the pressure-bonded side. The one provided with the treated adhesive can be used.

When the floppy disk 134 is inserted into the insertion slot 16 of the mounting table 12, the mark information written on the floppy disk 134 is stored in the RAM 126.
It is taken in. Therefore, when the sheet key 18 is operated, the cutting device 1 is operated by the system program and the like recorded in the RAM 126 and the ROM 124.
0 is drive-controlled.

That is, the rotary drive sources 46 and 76 are driven to transfer the heat cutter 100 at the original position to the cutting start position of the cloth 136 in advance. 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 rotates and is stretched between the pulley 48 and the roller 52. The first moving body 56 moves in the arrow X direction via the grooved belt 50.
On the other hand, the rotating drive shaft 76a
When the pulley 78 is rotated in a predetermined direction via the pulley 78, the second moving body 84 is similarly moved in the direction of the arrow Y by the grooved belt 82 stretched between the pulley 78 and the guide roller 62. Therefore, the heat cutter 100 is selectively moved in the two axial directions of the orthogonal coordinate system to reach the cutting start position of the cloth 136. At that time, the driving of the respective rotary driving sources 46 and 76 is stopped.

Next, the linear solenoid 64 constituting the displacement means 63 is driven to move the rod 64a to the tension spring 70.
Is displaced vertically downward against the tensile force. For this reason,
The swing member 66 engaged with the rod 64a swings vertically downward, and the swing member 66 and the guide bar 58a are displaced.
The support rod 72 held at the same time swings and displaces vertically downward. In this case, when the linear solenoid 64 is deenergized, the support rod 72 is
To hold the tip portion 108 of the heat cutter 100 above the cloth 136 (see a two-dot chain line in FIG. 3). Therefore, as described above, when the support rod 72 is swung vertically downward, the arm member 94 is swung vertically downward, and the tip portion 1 of the heat cutter 100 is rotated.
08 engages the fabric 136 in the desired pressurized state under the action of the pressurizing means 101 (see the solid line in FIG. 3).

As a result, the tip portion 108 heated to a predetermined temperature thermally cuts the cutting start portion of the fabric 136. At this time, the mounting plate 68 swings and engages with the shock absorber 75 under the action of the linear solenoid 64, so that the arm member 94 can be prevented from suddenly swinging. For this reason,
There is no possibility that the chip portion 108 of the heat cutter 100 collides with the arrangement plate 24 and damages the arrangement plate 24, for example.

Then, the rotary drive sources 46 and 76 are driven to move the tip portion 108 of the heat cutter 100 two-dimensionally along a desired trajectory, thereby performing a thermal cutting operation of the desired marks A, B and C. Is performed (see FIG. 6). When the tip portion 108 reaches the non-fused portion, the linear solenoid 64 is deenergized, so that the tension spring 70
The swinging member 66 is vertically displaced by the tensile action, and the supporting rod 72 integrally bridged by the swinging member 66 and the mounting member 74 moves vertically upward.
For this reason, the support rod 72 swings the arm member 94 vertically upward, and the tip portion 10 of the heat cutter 100 held by the arm member 94 via the grip portion 98.
8 are separated from the fabric 136.

Here, after the heat fusing operation is performed for a predetermined distance by the heat cutter 100, the heat cutter 1
In a state in which the tip portion 108 is separated from the cloth 136, the respective rotation driving sources 46 and 76 are driven to move the heat cutter 100 to the metal cleaning means 26 side. Further, the heat cutter 100 moves along a predetermined trajectory by selectively driving the rotary drive sources 46 and 76. Accordingly, the tip portion 108 engages with the plurality of wire members 32, and the deposited material is automatically and reliably removed from the tip portion 108. This heat cutter 100
Is moved to a desired thermal fusing operation position after the completion of the cleaning operation, and the thermal fusing operation of the marks A, B and C is performed.

In this case, in this embodiment, the metal cleaning means 2 is located near the original position of the heat cutter 100 as the cutting means.
6 are provided. For this reason, after the mark cutting operation is performed for a predetermined distance by the heat cutter 100 under the driving action of the moving mechanism 38, the heat cutter 100 is moved to the metal cleaning unit 26 via the control unit 120. Since the tip portion 108 moves while being engaged with the plurality of wire members 32, the tip portion 108 can be automatically and reliably cleaned. Then, by moving the heat cutter 100 to a desired heat fusing operation position, the next mark cutting operation can be quickly performed.

As described above, in the heat cutter 100, since the cleaning operation is automatically performed by the metal cleaning means 26 at predetermined intervals, the mark cutting operation is not interrupted for a long time. The effect that efficiency of the whole work is achieved is obtained. Moreover, there is no need for the operator to clean the heat cutter 100,
This has the advantage that the burden on the operator can be reduced and the mark cutting operation can be easily automated.

The cleaning operation of the heat cutter 100 may be performed each time a predetermined time elapses, or may be performed one character at a time, specifically, each time the heat fusing operation of each of the marks A, B, and C is completed. You can do it too. Further, in the present embodiment, the automatic cleaning operation of the heat cutter 100 has been described. However, the operator can arbitrarily instruct the cleaning operation of the heat cutter 100 by operating the sheet key 18.
