Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for a mark fabric or the like, and more particularly, to a moving mechanism that can be displaced in two axes of a rectangular coordinate system along a mounting table. A heat cutting means such as a heat cutter is mounted on the moving mechanism, and the heat melting means is automatically adjusted to a desired temperature so that a predetermined mark can be efficiently cut from a cloth or the like. The present invention relates to a device for cutting cloth or the like.

[Background of the Invention] Conventionally, markings, numbers, and the like have been generally applied to various uniforms for the purpose of clarifying their own workplaces and teams to which they belong, or for recognizing individuals. As this kind of mark, a crimping mark is generally widely used. That is, a pre-laminated adhesive is provided on the back side of the mark fabric, a desired mark is cut out from the fabric according to a mold, and the mark is positioned on an object to be crimped such as a uniform. The mark is engaged by melting the adhesive with a container or the like.
Here, when cutting out a predetermined mark from the cloth, a heat cutter (heat fusing device) has been conventionally used.

By the way, the cutting operation cannot be started with the heat cutter until the temperature becomes sufficiently usable. This is because if the heat cutter performs the cutting operation at a temperature lower than the predetermined temperature, it is difficult to reliably cut the fabric. Therefore, the cutting operation is usually started after a certain period of time has passed since the heat cutter is considered to have reached the predetermined temperature. As a result, it has been pointed out that a considerable amount of time is required for the preparation operation, and the efficiency of the entire cutting operation cannot be improved.

On the other hand, if the temperature of the heat cutter becomes higher than the predetermined temperature during the cutting operation, the fibers are discolored and burnt in some cases, and the quality is deteriorated, so that a mark having a desired shape cannot be cut out with high precision. In particular, when attempting to automate the cutting operation by automatically moving the heat cutter, if a temperature change occurs in the heat cutter itself, it becomes impossible to obtain a desired mark efficiently and accurately. Would.

Furthermore, if the temperature of the heat cutter drops below a predetermined temperature during the cutting operation, the cutting speed becomes slow, and productivity is poor.

[Object of the Invention] The present invention has been made in order to overcome the above-mentioned disadvantages, and is provided with a heat fusing means, for example, a heat cutter, on a moving mechanism that can be two-dimensionally displaced on a fabric mounting table. At the same time, a temperature adjusting means for detecting the temperature of the heat cutter itself and adjusting the temperature to a desired temperature is provided. It is an object of the present invention to provide a cutting device for a mark fabric or the like which enables a required mark to be cut out automatically and with high precision.

[Means for Achieving the Object] In order to achieve the above object, the present invention provides a mounting table on which a cloth or the like is mounted, and a movement displaceable along two axes of a rectangular coordinate system along the mounting table. A mechanism, a heat fusing means which is swingably attached to the moving mechanism under the action of an actuator, and cuts out a desired mark from the cloth or the like; a buffer means for controlling a swing operation of the heat fusing means; And a temperature adjusting means capable of adjusting the temperature of the fusing means itself to a desired temperature.

The arm member 94
A gripping part 98 made of a resin material is attached to the gripping part 98, and a thermal fusing unit, for example, a heat cutter 100 is mounted on the gripping part 98.

As shown in FIG. 4, the heat cutter 100 has a main body 102 substantially held by a gripper 98, and a rod-shaped heater (in a holder 104 attached to the main body 102). In effect, a ceramic heater) 106 is accommodated. A temperature measuring sensor, for example, a thermocouple 110 which constitutes a temperature adjusting means 108 is provided on a side peripheral portion of the heater 106, and a cloth (described later) is provided on the holder 104 near the tip of the heater 106. A chip portion 112 for thermally fusing is attached. In this case, the heater 106 is
It is connected to a power source (not shown) via a cord 114 extending from 102. Here, a flexible cord support 116 that is spirally wound is provided on the casing 14 that constitutes the cutting device 10, and the cord 114 is held by the cord support 116.

Further, the temperature adjusting unit 108 has a control unit 120.
That is, in FIG. 5, the control unit 120 substantially receives the desired set temperature from the sheet key 18, the set voltage value input from the CPU 122 via the output interface 124, and the thermocouple interface 126. A comparator 128 for comparing the input measured voltage value and supplying a predetermined current to the heater 106;

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

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 piece of cloth provided with a laminated adhesive 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 object to be pressed. One provided with the provided adhesive can be used.

Then, by operating the sheet key 18, the display unit 19 is operated.
To display the set temperature of the heat cutter 100,
This set temperature is input to CPU 122. For this reason, the set voltage is input to the comparator 128 via the output interface 124, a current is supplied to the heater 106, and the tip 112 of the heat cutter 100 is heated. The temperature of the heater 106 is measured by a thermocouple 110 and input to a comparator 128 via a thermocouple interface 126 as a measured voltage value. Then, the measured voltage value is compared with the set voltage value from the CPU 122, and current is supplied to the heater 106. After the temperature of the heater 106 reaches the set temperature, the heater 106 is maintained at the set temperature via the comparator 128. Is done. In addition, this heater 10
The temperature change of 6 can be visually recognized on the display unit 19.

In this way, when the heat cutter 100 reaches a desired temperature, the cutting device 10 is driven.

That is, in order to transfer the heat cutter 100 in the original position to the cutting start position of the cloth 136, the rotary drive sources 46 and 7
6 is driven. When the rotary drive shaft 46a is rotated in a predetermined direction under the driving action of the rotary drive source 46, a pulley 48 pivotally mounted on the rotary drive shaft 46a rotates, and a groove stretched between the pulley 48 and the roller 52. The first moving body 56 moves in the direction of the arrow X via the attached belt 50. On the other hand, when the pulley 78 is rotated in a predetermined direction through the rotary drive shaft 76a under the driving action of the rotary drive source 76, the pulley 78 is similarly extended by the grooved belt 82 stretched between the pulley 78 and the guide roller 62. The two moving bodies 84 move in the arrow Y direction. Therefore, the heat cutter 100 moves substantially in two axes of the orthogonal coordinate system to reach the cutting start portion of the cloth 136. At that time, the drive of the respective rotary drive sources 46 and 76 is stopped.

Next, the linear solenoid 64 constituting the displacement means 63 is driven to displace the rod 64a vertically downward against the tensile force of the tension spring 70. For this reason, the swinging member 66 engaged with the rod 64a swings vertically downward, and the support rod 72 held by the swinging member 66 and the guide bar 58a swings vertically downward. Dynamically displaces. In this case, in a state where the linear solenoid 64 is deenergized, the support rod 72 engages with the arm member 94 and the tip portion 1 of the heat cutter 100.
12 is held above the cloth 136 (see the two-dot chain line in FIG. 3). 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 tensile action of the tension springs 96a and 96b, and the arm member 94 swings vertically. Tip part 112 is cloth 13
6 (see the solid line in FIG. 3). by this,
The tip portion 112 heated to a predetermined temperature thermally cuts the cutting start portion of the fabric 136. At that time, the linear solenoid 64
Since the mounting plate 68 swings and engages with the shock absorber 75 under the action of, the arm member 94 can be prevented from suddenly swinging.
For this reason, the tip portion 112 of the heat cutter 100 is
For example, there is no risk of damaging the arrangement plate 24.

Then, the rotary drive sources 46 and 76 are driven and the heat cutter
By moving the 100 chip portions 112 two-dimensionally along a desired trajectory, the desired marks A, B and C are thermally melted (see FIG. 6). Here, when the tip portion 112 reaches the non-fused portion, the linear solenoid 64 is deenergized to cause the swing member 66 to swing vertically upward under the tension action of the tension spring 70, and this swing member 66 and mounting members
The support rod 72 integrally bridged with 74 is moved vertically upward. Therefore, the support rod 72 swings the arm member 94 vertically upward, and the tip portion 112 of the heat cutter 100 held by the arm member 94 via the grip portion 98 is separated from the fabric 136. .

After the desired marks A, B and C are thus thermally blown, the respective rotary drive sources 46 and 76 are driven while the tip portion 112 of the heat cutter 100 is separated from the cloth 136, and the heat cutter 100 is cut. Is moved to the cleaning means 26 side.
Further, the rotation driving source 76 is driven to move the second moving means 83 to the arrow Y.
When the tip portion 112 is moved along the direction toward the cleaning means 26 side, the tip portion 112 enters the slit groove 34 of the sponge body 32, and the tip portion 112 is cleaned by the sponge body 32 containing washing water. . Next, the rotary drive source 76 is driven to displace the second moving body 84 in a direction away from the housing 14 along the arrow Y direction, so that the tip portion 112 is separated from the sponge body 32 and the heat cutter 100 is moved. Is moved to a predetermined original position.

On the other hand, the cloth obtained by cutting the desired marks A, B and C
136 is removed from the arrangement plate 24, and a new cloth 136 is placed on the arrangement plate 24. At this time, the fabric 136 may be attached to the arrangement plate 24 by an adhesive provided on the back surface of the fabric 136. At this time, the operator's finger is inserted into the opening 22, and the arrangement plate 24 is attached to the cloth 136 after the completion of the cutting operation.
With the mounting table 12
The new placement plate 24 is placed on the new placement plate 20, and a new placement 136 is placed on the new placement plate 24. When a desired cutting operation is performed on the new cloth 136, as described above, the cloth 136 from the placement plate 24 to which the cut cloth 136 has been attached is attached.
It is only necessary to carry out the work of removing.

In this case, according to the present embodiment, the heat cutter 100
Since the temperature of itself is displayed on the display unit 19, the work of cutting the fabric 136 can be started immediately after the heat cutter 100 reaches a desired temperature. Therefore, unlike the related art, there is no need to wait for an unnecessarily long time after the power is turned on, and the cutting operation can be started quickly.

Moreover, the temperature of the heat cutter 100 is
Is always maintained at a predetermined set temperature. For this reason, there is no possibility that the cutting operation is continued, and the temperature of the tip portion 112 of the heat cutter 100 becomes higher than the set temperature, and the cloth 136 is blown out of a desired range. On the other hand, there is an advantage that the temperature of the heat cutter 100 does not become lower than a desired temperature, and the occurrence of the cutting failure of the fabric 136 can be prevented. by this,
The work of cutting marks from the cloth 136 can be performed with high precision, and in particular, an effect is obtained in which the cutting device 10 can automatically and efficiently perform the work of cutting marks.

[Effects of the Invention] As described above, according to the present invention, the thermal fusing means such as a heat cutter can be maintained at a desired set temperature.
Therefore, it is possible to cut out a desired mark efficiently and with high precision without causing a decrease in the efficiency of the mark cutting work due to a temperature change of the thermal fusing means, and to easily automate the mark cutting work. Is obtained.

As described above, the present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to these embodiments, and various improvements and design changes can be made without departing from the gist of the present invention. Of course.
