Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cloth pattern aligning apparatus, and more particularly, it is useful when the pattern on the cloth is continuous in at least the lateral direction, for example, a horizontal striped pattern or a lattice pattern. The present invention relates to an automatic fabric pattern aligning device that exhibits its function.

[0002]

2. Description of the Related Art In recent years, cloth-like fabrics such as clothes and Japanese clothes made of various materials have been commercially available. For example, a knitted fabric made by warp knitting is knitted into a tube shape. It is customary to dye and arrange the items, cut them open, and then roll them around a rod-shaped core in a round shape. In the case of unwinding and cutting the rolled fabric in this manner, first, the fabric is pulled out from the fabric and cut into a predetermined size, and the cut fabrics are laminated in multiple layers. After that, it is cut into a desired shape by using a cutting machine or the like. In this case, when the fabrics are stacked in multiple layers, it is necessary to perform pattern matching of the fabrics for each layer, and especially when the pattern of the fabrics is a striped pattern or a lattice pattern, pattern matching is performed accurately. If it is not, the product after cutting may have a skewed pattern, a bend, or the like, or may vary from product to product. Therefore, it is customary for the worker to perform manual patterning carefully so that the pattern of the cloth does not bend and the pattern of the cloth is the same in all layers.

[0003]

However, the cloth having the striped pattern or the lattice pattern as described above has already generated some skew or bending when it is pulled out from the original fabric. Because it appears as a habit of dough,
When fabrics are piled up in multiple layers to perform pattern matching, it is necessary for a large number of workers to stack the fabrics one by one and at the same time, one person must perform the work while checking the pattern position. This requires a lot of labor and time, and the work is complicated and troublesome, and work efficiency and productivity are inevitably deteriorated. In addition, the pattern matching of the dough is currently performed on the upper surface of the work table, that is, on the horizontal surface. When the doughs that are horizontally spread are stacked, the dough always shrinks or stretches. Therefore, the difficulty of the pattern matching work becomes more remarkable.

The present invention has been made in view of the above situation, and enables automation of the pattern matching operation of the cloth, which has been difficult in the past due to various characteristics of the knit cloth and the like. It is an object of the present invention to provide an automatic fabric pattern aligning device capable of improving the quality of the fabric and shifting the fabric after pattern matching to the fabric take-out side surely and smoothly without dropping.

[0005]

In order to achieve the above object, an automatic cloth pattern aligning apparatus according to claim 1 of the present invention comprises:
A fabric feeding mechanism that vertically unfolds the unfolded fabric that has been unwound from the original fabric, and an optical device that is placed opposite the hanging surface of the droopingly fed fabric to recognize the fabric pattern. It is configured to be movable in the front-rear direction and the vertical direction so as to face the reading means and the back surface side of the hanging part of the cloth, and the pattern matching needle is pierced into the cloth based on the signal from the optical reading means to vertically move the cloth. A plurality of pattern matching units for controlling the position in the direction, a cutter for cutting the pattern matched fabrics in the width direction, and a cutting device disposed opposite to the surface side of the cut fabrics. And a cradle that receives the dough receiving needle by piercing the dough, and a drive mechanism for the cradle that moves the cradle to the dough take-out position when a predetermined number of doughs are delivered to the cradle in a layered manner. With and When a predetermined number of fabrics are delivered to the recording tray in a laminated manner, the cradle that is in a vertical posture at the fabric receiving position each time the fabric receiving needle is pierced into the fabric is moved backward by the drive mechanism once. It is configured to be tilted by an angle and to be on standby.

Further, as the drive mechanism for the pedestal,
A cradle forward / backward moving cylinder that retreats the cradle every time a predetermined number of fabrics are stacked on the cradle, and a cradle rotation that rotates the cradle rearward in conjunction with the cradle moving backward. It is desirable to configure with a cylinder for use.

[0007]

According to the present invention, the cloth that is pulled out from the original fabric and expanded is sent out by the sending-out mechanism, and the end portion of the cloth is in a hanging state. Due to its own weight, habits such as skewing and bending are removed. The optical reading means, which is directed to the hanging portion of the cloth, reads the difference in color and shade in the pattern of the cloth, and the pattern matching unit is drive-controlled based on the reading result. At this time, the selected pattern matching unit is laterally moved according to the cloth width. Based on a signal from the optical reading means, pattern matching needles are sequentially stabbed into the cloth so that a specific portion of the pattern continuous in the lateral direction of the cloth matches one position in the vertical direction (vertical direction). The dough is positioned by moving it in the vertical direction, and finally, the dough is positioned so that the pattern continuous in the lateral direction becomes a straight line. If the dough is cut into a predetermined size in such a state, it is possible to avoid the adverse effects of skewing, bending, etc. of the dough, and to perform the subsequent overlapping work and cutting work well.

In particular, when handing over the cut and matched fabric to the pedestal, each time the fabric receiving needle on the pedestal pierces the fabric, the pedestal is once tilted backward by a predetermined angle. Therefore, the dough can be reliably and smoothly transferred to the cradle without causing the dough to fall off, and the dough receiving needle can be prevented from being subjected to a concentrated load due to its own weight of the dough. Breakage and deformation are prevented.

Further, if the pedestal on which a predetermined number of fabrics are laminated is moved backward while rotating the pedestal, the operation occupying space of the pedestal can be reduced.

The dough MA is fed by the dough feeding mechanism 4 described above.
After the trailing end of the pattern is sent out in a hanging shape, the pattern matching process of the cloth MA is performed by the cooperation operation of the CCD camera 5 and the pattern matching needle 6.

That is, the CCD camera 5 moves laterally along the rails 52 by driving the motor 54 to read the pattern of the cloth MA (process step N1 in FIG. 17). When the pattern is read by the CCD camera 5 (determination step N
2) Based on the reading result, the pattern matching needle 6 of each pattern matching unit 7 is moved (processing step N3).
That is, the microcomputer obtains the piercing distance D of the pattern matching needle 6 according to the cloth width from the signal that detects the width 1 of the cloth MA,
The number of pattern matching units 7 required is determined according to the distance D. Then, the motor 96 in the pattern aligning unit lateral movement device 9 is driven, the required number of pattern aligning units 7 are selected by the air chuck 92, the pin to be clamped 97 is pinched, and the pins are sequentially moved laterally and positioned at predetermined intervals. To do.

Subsequently, after analyzing the signal from the CCD camera 5 with a microcomputer or the like, the motor 73 in the pattern matching unit 7 is driven to drive the pattern matching needle 6 in the vertical direction,
It is moved to the same level as a specific position in the vertical direction of the horizontal striped pattern of the cloth MA, for example, a position where the color changes or a position where the shade changes. After that, the air cylinder 77 is driven to move the pattern matching needle 6 forward, so that the pattern matching needle 6 is pierced into the cloth MA as shown in FIG. 10 (processing step N4).

In this state, the motor 54 is driven to laterally move the air blowing device 57, and air Q is blown toward the surface of the cloth MA in the vicinity of the handle needle 6 as shown in FIG. 10 (processing step). N5). This allows the fabric MA
Is completely pierced by the handle 6.

At this time, since the pattern matching needles 6 are stabbed at intervals according to the cloth width l, unnecessary puncture scratches are not formed on the cloth MA and the quality of the cloth MA is improved. Can be maintained. The space may be adjusted by using all the pattern matching needles 6, but it is easier to select the piercing space D that matches the fabric width l by using only the necessary number.

When the pattern-matching needle 6 is completely inserted (decision step N6), the pattern-matching unit 7 is moved so that the pattern-matching needle 6 reaches an arbitrary predetermined position, and the CCD camera is further moved. 5 is moved, and based on the image data, by repeating this step, the cloth M
The horizontal stripes of A are exactly aligned on the horizontal line. Moreover, since the pattern matching needle 6 is pierced into the fabric MA and displaced in the vertical direction, there is no slippage and the pattern matching accuracy is extremely high.

When the pattern matching operation of the cloth MA is completed, each pattern matching needle 6 is moved to a predetermined cutting position as shown in FIG. Then, the motor 60 is driven to rotate the rotary cutter 10 by 90 ° from the storage position to change to the cutting position shown by the solid line in FIG. Next, the material MA is cut at a position about 10 mm above the handle needle 6 while driving the motor 62 to rotate the rotary cutter 10 and move it laterally along the rail 52. When the cutting of the cloth MA is completed, the rotary cutter 10 is stored, and the motor 73 of the pattern matching unit 7 is driven to lower the pattern matching needle 6 to a predetermined delivery position. The dough MA is set at the position opposite to the cradle 13 (see FIG. 1).
2).

The delivery operation of the cloth MA will be described with reference to the flowchart of FIG. First, the material receiving needle unit 116 is moved forward by the cylinder 117, and the material receiving needle 11 is pierced into the upper end portion of the material MA suspended from the pattern matching needle 6. Further, when the fabric receiving needle 11 and the push pin 118 are advanced by the cylinder 12, as shown in FIG.
Side needle holder 79 is pushed in and the pattern matching needle 6 is moved to the fabric M.
It acts so as to be extracted from A (processing step N11 in FIG. 18). At this time, since the push-in pin 118 pushes the needle holder 79, it is possible to prevent the fabric receiving needle 11 from accidentally hitting the needle holder 79 and being damaged.

After that, when the cylinder 77 on the handle needle 6 side is retracted (processing step N12), the cloth MA is delivered to the cloth receiving needle 11 side. That is, at this time, the fabric MA is suspended only by the fabric receiving needle 11.

When the fabric MA is received, the pedestal rotating cylinder 141 rotates the pedestal 13 from the vertical posture of the fabric receiving position to the backward posture by about 20 ° as shown in FIG. As shown in FIG. 15, the dough receiving unit 116 is provided by the cylinder 117.
Is retracted (processing step N13), and a standby state for receiving the next fabric MA is set. When the pedestal 13 is tilted backward when the above-mentioned fabric MA is received,
It is possible to prevent the material MA from dropping carelessly when the material is delivered, and moreover, the weight of the material MA is cradle 1
Since the material receiving needle 11 receives the material, the material receiving needle 11 is not broken or deformed.

Next, the cradle rotating cylinder 141 returns the cradle 13 to the vertical posture at the cloth receiving position (process step N14). Then, the same operation as described above is repeated until the predetermined number of pieces of the cloth MA is reached (processing step N15), and when the predetermined number is reached (judgment step N16), the above-mentioned patterns are aligned and cut into the predetermined size. The MAs are stacked on the pedestal 13 in multiple layers, and the process of taking out the cloth MA is started.

When the cloth MA is taken out, as shown in FIG. 16, the pedestal rotating cylinder 141 and the pedestal forward / backward moving cylinder 144 are actuated to move the vertical pedestal 13 backward while rotating it. Therefore, the receiving table 13 is set upward at the cloth take-out position adjacent to the cutting table 145. At this time, if the cradle 13 is rotated and retracted by independent operations, the occupied space for the operation becomes large. However, by operating the pedestal 13 in rotation and retreat in a linked relationship as described above, Can be reduced.

After that, when the cloth receiving needle unit 116 is retracted by the cylinder 117, the cloth receiving needle 11 is pulled out from the laminated cloth MA. After this, cutting table 1
The multi-layered cloth MA is transferred onto 45 and cut by a cutting machine (not shown).

In the above embodiment, the fabric M is struck by the rotary cutter 10 with the pattern matching needle 6 piercing the fabric MA.
A was cut, but as shown in FIG. 19, with the pattern matching needle 6 and the cloth receiving needle 11 piercing the cloth MA, the cloth cutter MA should be cut by the rotary cutter 10 at a position between both needles 6 and 11. You may In this case, since the cut portion of the cloth MA is held by both the needles 6 and 11, the cutting operation of the rotary cutter 10 can be performed sharply and the cloth MA can be delivered more reliably.

[0041]

As described above, according to the first aspect of the present invention, the plurality of pattern matching units arranged to face the back side of the hanging portion of the cloth that is drooped by the cloth feeding mechanism. Since each pattern matching needle is moved based on the signal from the optical reading means facing the surface side of the fabric, the pattern matching of the fabric can be performed accurately and automatically, and the pattern matching is cut. When the fabric is pierced into the fabric receiving needle on the pedestal side, the pedestal is tilted backward, so the fabric may fall off during delivery, or the weight of the fabric may act on the receiving needle to cause the receiving needle to move. There is no fear of breaking or deforming, and it is possible to reliably and smoothly demonstrate the smooth cloth transfer function.

According to the second aspect of the present invention, since the pedestal is rotated while being retracted, the operating space of the pedestal can be made as small as possible, and the occupied space of the entire apparatus can be reduced.
