Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a cutting device for marking fabric, etc. - More specifically, it includes a moving mechanism that can be freely displaced in two axes of an orthogonal coordinate system along a mounting table. A cutting means such as a heat cutter is attached to the moving mechanism, and a cleaning means made of corpus cavernosum or the like is provided, and the cutting means is automatically cleaned by the cleaning means to cut a desired mark from the fabric or the like. The present invention relates to a cutting device for marking cloth, etc., configured to cut efficiently.

[Background of the Invention] Conventionally, it has been common practice to add marks, numbers, etc. to various uniforms for the purpose of clarifying one's workplace, team to which he or she belongs, or for 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, the following method has conventionally been used.

First, as shown in FIG. 1a, the fabric 4 is placed on the placement plate 2, and then a mount 6 having a desired mark shape is formed in advance, and this mount 6 is placed on the fabric 4. do(
(See Figure 1).

Further, as shown in FIG. 1C, a desired mark is thermally cut from the fabric 4 by moving a heat cutter (thermal cutter) 8 as a cutting means along the mount 6, and the mark is from the placement plate 2.

However, in the conventional method described above, it is necessary to prepare a mount 6 corresponding to the shape of the mark in advance, and when there are many different shapes of marks, the process of manufacturing the mount 6 itself becomes quite complicated. turn into. Moreover, in order to cut the marks, the operator essentially has to move the heat cuffer 8 along the mount 6, which tends to cause variations in the shape of the marks to be cut. It has been pointed out that there is an inconvenience in not being able to carry out the project.

Therefore, there is a need for a cutting device that automatically performs the mark cutting operation, but in this case, cleaning of the cutting means in particular becomes a problem. That is, as described above, when the heat cuffer 8 performs a thermal cutting operation on the fabric 4, a welded material consisting of the fabric 4 itself and the adhesive is likely to be formed at the tip of the heat cuffer 8. Therefore, the work of removing the welded material from the heat cutter 8 must be performed relatively frequently, and in practice, it is necessary for the operator to stop driving the cutting device and clean the heat cutter 8 himself. Therefore, the mark cutting operation is often interrupted, and the mark cutting operation cannot be efficiently performed, and furthermore, it is difficult to automate the mark cutting operation.

[Object of the Invention] The present invention has been made to overcome the above-mentioned disadvantages, and includes a cutting means such as a heat capter attached to a moving mechanism that is two-dimensionally displaceable on a fabric mounting table, and A cleaning means made of corpus cavernosum or the like is placed on the writing table near the original position of the cutting means, and after the desired mark cutting operation is completed or after a predetermined time has elapsed, the cutting means is moved and the cleaning means automatically removes the cutting means. The present invention is designed to perform the cleaning work automatically, thereby making it possible to carry out the cleaning work without interrupting the mark cutting work, and to automatically and efficiently cut out the desired mark from the cloth. The purpose is to provide a cutting device.

[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. and a cutting means attached to the moving mechanism to cut out a desired mark from the cloth or the like, and a cleaning means for displacing the cutting means under the action of the moving mechanism and automatically cleaning the cutting means.

It has an M126, an FD interface 128, a sheet key interface 129, and a moving mechanism interface 130, which are interconnected by a path line 132 consisting of a data bus, a control bus, and the like.

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 the information of desired marks A, B, 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.

In this case, the fabric 136 may be a single piece of fabric with a laminated adhesive on the back side, or a mark fabric and a base fabric that are polymerized and then laminated on the side of the base fabric that faces the object to be pressed. It is possible to use one provided with an adhesive.

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

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 grooved belt 82 similarly stretched between the pulley 78 and the guide roller 62 causes the 2 moving body 84 moves in the direction of arrow Y. Therefore, the heat cutter 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 106 of the heat cutter 100 above the fabric 136 (in FIG. 4, (See double-dashed line). Therefore, as described above, when the support wand 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 is made of cloth 136
(see solid line in Figure 4). As a result, the tip portion 106 heated to a predetermined temperature is exposed to the cloth 136.
The cutting start site is thermally cut.

Therefore, under the driving action of the control section 120, the rotary drive source 46.
76 to drive and control the tip portion 1 of the heat cutter 100.
06 two-dimensionally along a desired trajectory, the desired marks ASB and C are thermally cut (see Fig. 7).Here, when the tip portion 106 reaches the non-melting part, By deenergizing the linear solenoid 64, the rocking member 66 is rocked vertically upward under the tension of the tension spring 70, and is integrally bridged with the rocking member 66 and the mounting member 74. The support rod 72 is moved vertically upward. Therefore, the support rod 72 swings the arm member 94 vertically upward, and the tip portion 106 of the heat cutter 100 held by the arm member 94 via the grip portion 98 separates from the fabric 136. .

After the desired marks ASB and C are thermally cut in this way, the tip portion 106 of the heat cutter 100 is cut off from 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 direction of arrow Y, the tip part 106 enters the slit groove 34 of the corpus cavernosum 32, and the cleaning water The cleaning operation of the tip n106 is performed by the corpus cavernosum 32 containing the above (see FIG. 5). Next, the rotational drive source 76 is driven so that the second movable body 8
4 in a direction away from the housing 14 along the direction of arrow Y, the tip portion 106 is separated from the corpus cavernosum 32, and the heat cuffer 100 is moved to a predetermined original position.

On the other hand, the fabric 1 cut with the desired marks ASB 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 worker 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 this fabric 136 from the placement plate 24 to which 6 is attached.

In this case, according to this embodiment, the cleaning means 26 is mounted on the mounting table 12 near the original position of the heat cuffer 100, which is the cutting means. For this reason, the moving mechanism 38
After the heat cutter 100 finishes cutting a predetermined mark under the driving action of the heat cutter 100, when the heat cutter 100 is moved toward the cleaning means 26 via the control section 120, the tip section 106 cuts into the slit groove 34 of the corpus cavernosum 32. The tip section 106 can be automatically cleaned by entering the room.

Next, by moving the heat cutter 100 to a predetermined original position, it becomes possible to quickly perform the next mark cutting operation.

In this way, before moving the heat cutter 100 to its original position, the cleaning means 26 cleans the heat cutter 100.
Since the cleaning is performed automatically, the overall efficiency of the mark cutting operation can be improved without interrupting the mark cutting operation. Moreover, heat cutter 10
There is no need for the operator to clean the 0 himself/herself, which reduces the burden on the operator, and has the advantage that the mark cutting work can be easily automated.

Here, the cleaning work of the heat cutter 100 may be performed every time a predetermined time elapses, or it may be performed every time the heat cutting work for each character, specifically, each of the marks ASB and C is completed. I can do it.

Note that in this embodiment, the heat cuffer 100 is used as the cutting means, but for example, a gas torch may be used. In this case, the gas torch may be remotely controlled by wireless or the like.

Furthermore, in the X-Y block, which is generally used for drawing line drawings on paper, it is also possible to configure the cutting device by attaching a cutting means such as a heat cutter in place of the pen.

[Effects of the Invention] As described above, according to the present invention, marks such as desired letters and numbers are automatically cut out from cloth etc. using a cutting means such as a heat cutter, and at the same time, marks such as desired letters and numbers are automatically cut out from cloth etc., and welded materials etc. that adhere to the cutting means are removed. can be automatically and easily removed. Therefore, there is no need to interrupt the mark cutting operation to clean the cutting means, and moreover, the cleaning operation can be carried out more quickly than when the operator himself or herself cleans the mark. This provides the effect that efficiency and automation of the entire mark cutting operation can be easily achieved.

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.
