Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fabric disassembling device for disassembling a cloth-like material in a wound state as an original material,
More specifically, the present invention relates to a device that plays a part in automating the process of unrolling a raw material, expanding the material, and then sequentially cutting the material into pieces.

[0002]

2. Description of the Related Art In recent years, cloth-like cloths such as clothes and Japanese cloths made of various materials have been commercially available. For example, warp-knit knitted cloth is knitted into a tube shape. It is customary to dye and arrange the fish, cut it open, and then wind it round a rod-shaped core to finish it. With respect to the steps from unwinding the wound roll to the cutting process in the above-described manner, automation has hardly been achieved in the past, and therefore, usually, the cutting process is performed prior to the cutting process. A means has been adopted in which an operator grips the end edge (rolling end portion) of the item (1) and pulls out the dough by a predetermined dimension, and then sequentially cuts it using a cutting blade or the like.

[0003]

However, if the original fabric is unraveled manually by the operator prior to the cutting process as in the above-mentioned conventional technique, a large number of manpower and labor are required. The work becomes complicated and troublesome, and work efficiency and productivity are inevitably deteriorated. Also,
Since the above-mentioned material is relatively tightly wound, it is extremely difficult to automatically detect the end edge of the material, and in addition, the material of the cloth is flexible. It cannot be handled easily, and as a result, there is a significant delay in automation technology for the work of unwinding the material.

The present invention has been made in view of the above circumstances, and makes it possible to automate the unraveling work, which has been difficult in the past due to various characteristics of the original fabric, thereby improving work efficiency and productivity. It is a technical issue to improve the production cost and to reduce the production cost.

[0005]

The automatic fabric disentangling apparatus according to the present invention is characterized in that it is configured as follows in order to achieve the above technical problems. That is, rolling means for rolling the raw fabric around the axis, air jetting means for jetting air toward the fabric end portion of the raw fabric to float the fabric end portion, and the floated fabric end portion. And a arm member for rotating the hook member at a predetermined radius of gyration.

[0006]

According to the above-mentioned technical means, first, the roll is rotated around the axis by the action of the rolling means (for example, the driving roller). In this case, the rolling direction (rotational direction)
Must be in the same direction as the winding direction of the fabric in the original fabric. Then, if air is ejected from the air ejecting means to the outer peripheral surface of the original fabric while the original fabric is rolling, the injection position of this air and the fabric end portion (winding end portion) of the original fabric match. At that time, the fabric end portion is floated by the action of air. By pivoting the arm member in such a state, the hook member pulls and moves the fabric end portion along a predetermined arcuate path, whereby the fabric is pulled out from the original fabric by a predetermined size and expanded. Become. In this way, by the operation of the rolling means, the air injection means, the hook member, and the arm member, the unwinding work of the original fabric is automatically performed, and the cutting work is performed after one unwinding work is performed. If this is performed and this is continuously repeated, it is possible to achieve continuous automation of the steps from the unwinding of the original fabric to the cutting process.

X placed on the original fabric base 1 are automatically lifted up one by one by the original fabric elevator 2, and when the upper end is reached, the mounting base part is placed. The slope 2a rolls to reach the unwinding position S.

As shown in FIG. 4, the automatic fabric disassembling apparatus 3 has rolling means consisting of a first driving roller 21, a second driving roller 22 and four auxiliary rollers 23 ...
The first and second drive rollers 21 and 22 can be rotated forward and backward by a motor (not shown). Further, in front of the first drive roller 21, there is provided an air injection means having injection holes 26 ... 26 formed on the upper surface of the air circulation pipe 25. This air injection means is as shown in FIG. Further, the air pressure-fed via the air hoses 27 ... 27 is jetted upward from the injection holes 26 ... 26 of the air flow pipe 25 as shown by the arrow. Further, as shown in FIG. 4, a hooking member made of a wire 28 is stretched just before the air flow pipe 25, and both ends of the wire 28 are
A pair of arm members 29 ... 2 which can be swung with a predetermined radius of gyration
It is fixed to the front end portion of 9. The arm member 29 is forcibly turned by the motor 30 about the support shaft 31. As shown in FIGS. 6 and 7, the end portion of the wire 28 is fastened to the arm member 29 using the wing nut 32, and this fastening point can be changed along the circular hole 33. It is possible. Also, FIG.
As shown in FIG. 3, the air hose 27 is connected to a small compressor 27a, and this small compressor 27a is attached to the lower part of the material elevator 2 as shown in FIG. According to the configuration of the automatic fabric disassembling apparatus 3 as described above, as shown in FIG.
By rotating 1 in the direction of the arrow, the original fabric X conveyed to the unwinding position S is rolled in the counterclockwise direction, and at the same time, air is supplied from the air flow pipe 25 of the air injection means to the outer peripheral surface of the original fabric X. To spray. As a result, the cloth end portion Xa (winding end portion) of the original fabric X floats up with the air jetting. Under such a state, the air jetting is stopped or the arm member 29 is slightly moved. Manually rotate the cloth end portion Xa of the wire 28 by turning it clockwise.
If the contact is made with the pressure sensor, the fact that the pressure is applied is detected by a pressure sensor or the like, and the motor 30 is activated in response to this detection,
The arm member 29 pivots about 180 ° as shown by the chain line in the figure while the cloth end portion Xa is hooked on the wire 28.
Along with this, the cloth end portion Xa passes above the belt 4 and reaches the rear of the belt 4, and the cloth is spread. still,
The detection of the activation start timing of the motor 30 is not limited to the use of the pressure sensor or the like as described above, but an optical device for detecting that the edge of the fabric end portion Xa in a lifted state has reached a predetermined front position. It is also possible to use a physical sensor or the like.

After the original fabric X is unwound and the fabric is spread over a predetermined size in this manner, the following processing is performed. That is, the explanation will be made by comparing FIG. 9 with FIG. 1. After the cloth is spread over the upper surfaces of the belts 4 ... 4, a signal from a sensor that detects that the arm member 29 has reached the turning end, etc. On the basis of the above, the first driving roller 21 and the second driving roller 22 rotate in the clockwise direction to feed the cloth. In this case, since the surface of the belts 4 ... 4 has a large friction coefficient, the belt 4 And the second drive roller 2
2 and a slack portion Xb of the cloth is generated, and the rotation of the first and second drive rollers 21 and 22 is stopped when the cloth slack amount control sensor 35 detects that the slack amount has reached a predetermined amount. To do. After that, the fabric is sent out by the belts 4 ... 4 and descends along the surface of the vacuum plates 7 ... 7, but the deviation of the fabric in the left-right direction (xy direction) at the time of this descending is the fabric width. Based on the detection result detected by the sensor 36, the belts 4 ... 4 are moved in the left-right direction, or the slide members separately provided are engaged with the left and right ends of the cloth and moved in the left-right direction. Adjust the gap. Then, when the lower end position control sensor 37 detects that the lower end of the cloth has descended to a predetermined position, the feeding of the cloth by the belts 4 ... 4 is stopped.

After this, a plurality of CCD cameras 5
.. 5 and the respective belts 4 ... 4 perform the pattern matching processing of the cloth. In this case, the CCD camera 5 detects the difference in color or the light and shade, and this detection signal is controlled. It is sent as a drive signal to the belt 4 located at the opposite position via a means (for example, a microcomputer). Then, in order from the left end or the right end, pattern matching with respect to the horizontal direction of the cloth between the corresponding CCD cameras 5 and the belt 4, that is, a work of horizontally matching the horizontal stripes of the cloth is performed. After this pattern matching work is completed, the compressor 6 is started to activate the small through holes 7a ... 7 of the vacuum plates 7 ... 7.
By applying a negative pressure to the cloth through a, the cloth is sucked onto the surface of the vacuum plates 7 ... 7 and the rotary cutter 41 (see FIG. 3) installed on the tool rest 40 is moved along the guide rail 42. By doing so, the dough cutting process is performed.

After the above cutting process is completed, the moving frame 11 is moved to the rail 1 by the operation of the air cylinders 50, 50.
It is moved forward along 0, 10 so that the needle plate 9 is pressed against the vacuum plates 7 ... 7 as indicated by the chain line in FIG. In this case, since a plurality of needles 8 ... 8 are attached to the upper end portion of the needle plate 9, the needles 8 ... 8 are attached to the cut cloth.
Will be stuck. It should be noted that, above the vacuum plates 7 ... 7, narrow grooves or small-diameter holes are formed so that the needles 8 ... Next, in such a state, the suction of the cloth due to the negative pressure is released, and the air is passed through the vacuum plates 7 ... 7 from the back side of the vacuum plates 7 ... 7 by the operation of an air blowing device (not shown). 8 ... By blowing the cloth close to the needle plate 9 by blowing in the vicinity of 8 to eliminate the curl and the like of the cloth, and then by moving the needle plate 9 by the operation of the air cylinders 50, the cutting is performed. The material thus stabbed is returned to a predetermined position together with the needle plate 9 while being pierced by the needles 8 ... By repeating the above-mentioned steps, the cut fabrics having a predetermined size are superposed on the needle plate 9 in multiple layers while patterning the fabrics.

After the above-mentioned superposition work is completed, the needle plate 9 in the vertical state is rotated by 90 ° about the rotation supporting shafts 9b, 9b manually or by using a motor or the like, as shown in FIG. In this way, the needles 8 ... 8 are moved horizontally by the operation of the needle driving air cylinders 60, 60 attached to the left and right ends of the needle plate 9, and then pulled out from the cloth. Then, after that, the multi-layered cloth is transferred to the cutting table 80 that can move toward and away from the throat plate 9, and cutting is performed by a cutting machine (not shown).

In the automatic fabric disassembling apparatus 3 according to the present invention described above, the drive rollers 21, 22 and the auxiliary roller 23 are provided.
The number of 22 is not limited to that shown in the figure,
