Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cutting device for marking cloth, etc., and more specifically, a moving mechanism that can be freely displaced in two axes of an orthogonal coordinate system along a mounting table. and a thermal cutting means such as a heat cutter is attached to the moving mechanism, and the thermal cutting means is automatically adjusted to a desired temperature to efficiently cut a predetermined mark from cloth or the like. This invention relates to cutting devices for fabrics, etc.

[Background of the Invention] Conventionally, various types of uniforms have been decorated with marks, numbers, etc. for the purpose of clarifying one's workplace, the team to which he or she belongs, or for the purpose of individual recognition. As this type of mark, crimp marks are usually widely used.

That is, a laminated adhesive is provided on the back side of the marking fabric in advance, a desired mark is cut out from this fabric according to the pattern, the mark is positioned on an object to be pressed such as a uniform, and then a thermocompression press is applied. The mark is attached by melting the adhesive using a container or the like. Here, when cutting out a predetermined mark from cloth, a heat cutter (thermal cutter) has conventionally been used.

By the way, with the heat cutter, the cutting operation cannot be started until the temperature reaches a sufficiently usable temperature. This is because if the heat cutter performs the cutting operation at a temperature lower than a predetermined temperature, it will be difficult to reliably cut the fabric.

Therefore, normally, after a certain amount of time has elapsed from the time when the heat cutter seems to have reached the predetermined temperature,
Cutting work begins. It has been pointed out that this causes a disadvantage that the preparation work takes a considerable amount of time and efficiency of the cutting work as a whole cannot be achieved.

On the other hand, if the heat cutter reaches a higher temperature than a predetermined temperature during the cutting operation, the fibers will change color and even burn, resulting in poor quality and the inability to cut out marks in the desired shape with high precision. In particular, when trying to automate cutting work by automatically moving a heat cutter, if the temperature of the heat cutter itself changes, it becomes impossible to efficiently and accurately obtain the desired mark. I end up.

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

[Object of the Invention] The present invention has been made to overcome the above-mentioned disadvantages, and includes a moving mechanism capable of two-dimensionally displacing the fabric mounting table with a thermal cutter, for example, a heat cutter. At the same time, a temperature adjustment means is provided to detect the temperature of the heat cutter itself and adjust it to a desired temperature, thereby eliminating the possibility of defective mark cutting due to temperature changes of the heat cutter itself, and improving the quality of the fabric. An object of the present invention is to provide a cutting device for marking cloth, etc., which makes it possible to cut out a desired mark automatically and with high precision from a cloth.

[Means for Achieving the Object] In order to achieve the above-mentioned object, the present invention provides a mounting table on which a fabric or the like is placed, and a moving mechanism that can be freely displaced in two axes of an orthogonal coordinate system along the mounting table. The present invention is characterized by comprising: a thermal fusing means attached to the moving mechanism to cut out a desired mark from the cloth or the like; and a temperature adjusting means capable of freely adjusting the temperature of the thermal fusing means itself to a desired temperature.

A tension spring 70 is tensioned between them. Furthermore, the mounting plate 68 includes a support rod 7.
One end of 2 is fixed. This support rod 72 has a length corresponding to the displacement range of the second moving means in the direction of arrow Y, which will be described later, and extends parallel to the guide bar 58a, and the other end of the support rod 72 is connected to the guide bar 58a. It is attached to a mounting member 74 that swingably engages with the end edge of. Also,

is installed.

As shown in FIG. 4, the heat cutter 100 has a main body part 102 that is substantially held by a grip part 98, and a rod-shaped heater ( Substantially, ceramic heater)1
06 is accommodated.

0 A temperature measurement sensor, such as a thermocouple 110, constituting the temperature adjustment means 108 is provided on the side circumference of the heater 106, and a cloth (described later) is provided in the holder portion 104 near the tip of the heater 106. ) is attached. In this case, heater 1
06 is connected to a power source (not shown) via a cord 114 extending from the main body 102. Here, the casing 14 constituting the cutting device 10 is provided with a flexible cord support 116 wound spirally, and the cord 114
is held on this coat support 116.

Furthermore, the temperature adjustment means 108 has a control section 120. That is, in FIG. 5, the control unit 120 substantially controls the C
P U 122 and a comparator 1 that compares a set voltage value manually inputted from the CPU 122 via the output interface 124 with a measured voltage value manually inputted from the thermocouple interface 126 and supplies a predetermined current to the heater 106.
28.

The cutting device according to this embodiment is basically constructed as described above, and its operation and effects will be explained next.

First, the floppy disk 13 is loaded by an FDD (not shown).
4, write information on desired marks Δ, B1 and C.

Meanwhile, the power is turned on in the cutting device 10,
The fabric 136 to be cut is placed on the placement plate 24, and the floppy disk 134 is inserted into the insertion opening 16 formed in the placement table 12. In this case, the fabric 136
For example, a laminated adhesive is applied to the back side of a single piece of fabric, or a mark fabric and a base fabric are polymerized and a laminated adhesive is applied to the side of the base fabric that faces the object to be pressed. You can use what is provided.

Therefore, by operating the sheet key 18, the display section 1
9 displays the set temperature of the heat cutter 100, and also inputs this set temperature to the CPU 122 manually. For this purpose, the comparator 128 via the output interface 124
A set voltage is input to (1) 2. A current is supplied to the heater 106, and the tip portion 112 of the heat cutter 100 is heated. Said heater 1
The temperature of 06 is measured by a thermocouple 110 and inputted as a measured voltage value to a comparator 128 via a thermocouple interface 126. Then, the measured voltage value and CPU
122 is compared with the set voltage value from heater 106.
After the temperature of the heater 106 reaches the set temperature, the temperature of the heater 106 is maintained at the set temperature via the comparator 128.

Note that the temperature change of the heater 106 can be visually confirmed on the display section 19.

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

That is, the rotary drive sources 46 and 76 are driven to move the heat cutter 100, which is previously in the original position, to the cutting start position of the fabric 136. 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 attached to the shaft rotates.
The first moving body 56 moves in the direction of the arrow X via the grooved belt 50 stretched between the roller 52 and the roller 52 . 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, the boot 1
A second moving body 84 is moved in the direction of arrow Y by a grooved belt 82 stretched between the roller 8 and the guide roller 62. Therefore, the heat canku 100 is substantially 2 in the orthogonal coordinate system.
It moves in the axial direction and reaches the cutting start site of the fabric 136. At that time, the driving of each rotary drive source 46, 76 is stopped.

Next, the near 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. Therefore, the rod 64a
The swinging member 66, which is engaged with the guide bar 58a, swings vertically downward, and the support rod 72, which is held by the swinging member 66 and the guide bar 58a, swings vertically downward. In this case, when the linear solenoid 64 is deenergized, the support rod 72 engages with the arm member 94 and holds the tip portion 112 of the heat cutter 100 above the fabric 136 (Fig. 3). middle, see double-dashed line). Therefore, as described above, when the supporting door 2 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. The tip portion 112 is made of cloth 136
(see solid line in Figure 3). As a result, the tip portion 112 heated to a predetermined temperature is exposed to the cloth 136.
The cutting start site is thermally cut. At this time, since the mounting plate 68 swings under the action of the linear solenoid 64 and engages with the shock absorber 75, it is possible to prevent the arm member 94 from swinging suddenly. Therefore, the chip portion 112 of the heat cutter 100 collides with the arrangement plate 24, and, for example,
There is no risk of damaging 4.

Therefore, by driving the rotary drive source 46.76 and moving the tip portion 112 of the heat cutter 100 two-dimensionally along a desired trajectory, the desired marks A, B, and C are thermally cut out ( (See Figure 6). Here, when the tip part 112 reaches the non-melting part, the beam near solenoid 6
4, the swinging member 66 is swung vertically upward under the tension of the tension spring 70, and the support rod 72, which is integrally bridged with the swinging member 66 and the mounting member 74, is moved vertically. Move it 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 attached to the fabric.
This leads to separation from 36.

After the desired marks A, B, and C are thermally cut in this manner, the tip portion 112 of the heat cutter 100 is cut onto the fabric 1.
Each rotary drive source 46.76 is spaced apart from 36.
is driven to move the heat cutter 100 to the cleaning means 26 side. Further, when the rotational drive source 76 is driven and the second moving means 83 is moved toward the cleaning means 26 side along the arrow Y direction, the tip part 112 enters the slit groove 34 of the corpus cavernosum 32, and the cleaning water The cleaning operation of the tip portion 112 is performed by the corpus cavernosum 32 including the corpora cavernosa 32 . Next, the rotational drive source 76 is driven to displace the second movable body 84 in the direction of arrow Y in a direction away from the housing 14, thereby detaching the tip portion 112 from the corpus cavernosum 32 and heating it. The cutter 100 is moved to a predetermined original position.

On the other hand, the fabric 1 cut with desired marks A, B and C
36 is removed from the placement plate 24, and a new fabric 136 is placed on this placement plate 24. At this time, the fabric 136 may be attached to the placement plate 24 by an adhesive provided on the back surface of the fabric 136. At this time, the operator inserts his or her finger into the opening 22, removes the placement plate 24 from the mounting table 12 together with the fabric 136 after the cutting operation is completed, and inserts a new placement plate 24 into the recess 20 of the placement table 12. Then, a new fabric 136 is placed on this new placement plate 24. When performing a desired cutting operation on this new fabric 136, the fabric 136 after cutting is cut as described above.
What is necessary is to remove the fabric 136 from the placement plate 24 to which the fabric 36 is attached.

In this case, according to this embodiment, the heat cutter 100
Since the temperature of the heat cutter 100 is displayed on the display section 19, the temperature of the fabric 13 is displayed immediately after the heat cutter 100 reaches the desired temperature.
6 cutting operation can be started. Therefore, it is not necessary to wait for an unnecessarily long time after turning on the power, unlike in the conventional case, and it becomes possible to start cutting work quickly.

Moreover, the temperature of the heat cutter 100 is controlled by the temperature adjusting means 1.
The temperature is always maintained at a predetermined temperature by the control unit 120 that constitutes 08. Therefore, there is no risk that the tip portion 112 of the heat cutter 100 will become hotter than the set temperature by continuing the cutting operation, and the fabric 136 will be fused to a point outside the desired range. On the other hand, heat cutter 10
0 is never lower than the desired temperature and the fabric 136
This has the advantage that cutting defects can be prevented from occurring. Thereby, it is possible to perform the mark cutting operation from the fabric 136 with high precision, and in particular, the cutting device 10
This provides the effect that the mark cutting work can be performed automatically and efficiently.

[Effects of the Invention] 7.8 As described above, according to the present invention, it is possible to maintain a thermal cutting means such as a heat cutter at a desired set temperature. Therefore, there is no reduction in the efficiency of mark cutting work due to temperature changes in the thermal cutting means, and the desired mark can be cut out efficiently and with high precision, and the mark cutting work can be easily automated. The effect is that it becomes possible to achieve the following.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments.
Of course, various improvements and changes in design are possible without departing from the gist of the present invention.
