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, the operator can cut the dough into a predetermined size one by one on the horizontal workbench.
Do not pull the fabric from both sides after transferring and spreading it on the top surface.
Adjust the fabric pattern so that it does not bend , and
Make the same adjustments when stacking the next fabric on the prepared fabric.
It is customary to carefully and manually perform pattern matching so that the patterns of the upper and lower fabrics are 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 workbench, that is, on the horizontal surface. When the doughs that are horizontally spread are stacked, the doughs must be contracted or expanded individually. Occurs on all fabrics that
It is not a problem as long as it is even.
However, since it is manual work, variations may occur.
Not be avoided and, therefore, the difficulty of the pattern matching work
In addition to being more prominent, it has sufficient pattern matching accuracy.
It wasn't.

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 that can improve the pattern quality and can perform pattern matching with extremely high accuracy without damaging the fabric.

[0005]

In order to achieve the above object, an automatic cloth pattern aligning apparatus according to claim 1 of the present invention comprises:
An optical system that recognizes the fabric pattern by arranging the fabric feeding mechanism that vertically unwinds the unfolded fabric unfolded from the original fabric and the hanging surface of the drooping fabric. 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 side of the hanging part of the cloth, and the pattern matching needle is moved in order based on a signal from the optical reading means.
To pierce the next fabric and move it vertically
Therefore, the pattern that is continuous in the lateral direction on the fabric is a straight line.
And a plurality of pattern registration unit for controlling the vertical position of the fabric so that, together with the laterally movably supporting said handle registration unit individually, spacing piercing of the pattern matching needles according to the fabric width It is provided with a lateral movement device for adjusting the pattern matching unit.

The pattern aligning unit lateral movement device may be configured to select the number of pattern aligning needles to be used according to the cloth width.

[0007]

According to the present invention, fed by the mechanism feeding the dough which is spread it is pulled from Genhan, the feed
Because out dough in a state of being suspended from one end of the delivery mechanism, the dough portion that the droop becomes the natural state in which habit such as skew or bend that been removed the under its own weight.
The optical reading means, which is directed to the material portion that hangs down in this natural state, reads the difference in color and shade in the pattern of the material, and the drive of a plurality of pattern matching units is controlled based on the read result. . In this case, selected ones of the pattern registration unit depending on the fabric width by lateral movement of a given
Matching is done. That is, the pattern matching needle is sequentially moved forward based on a signal from the optical reading means 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). Longitudinal
Rukoto to move the dough in a vertical direction crowded stabbed in a specific location
Allows the fabric to move vertically at multiple points across its width.
After being positioned, the pattern continuous in the lateral direction on the cloth becomes a straight line shape . In this way, the fabric naturally
Multiple handle needles with the habit removed by hanging them
Use the to straighten a horizontal continuous pattern on the fabric.
It is sent out one after another by repeating the work of aligning
For all coming fabrics, their lateral succession
It is possible to evenly arrange the patterns without variation. In this state, cut the dough into specified dimensions and stack them.
By doing so, it is possible to avoid adverse effects due to habits such as skewing and bending of each fabric, perform pattern matching with high accuracy, and to perform subsequent overlaying work and cutting work satisfactorily.

Particularly, since the interval between the piercing positions of the pattern matching needles of the pattern matching unit is adjusted according to the width of the cloth,
Do not pierce the fabric unnecessarily with pattern matching needles,
The quality of the fabric is guaranteed with less damage.

Further, if the number of pattern matching needles is selected according to the width of the cloth, it becomes easy to adjust the piercing interval for the cloth.

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 required number of pattern matching units 7 is determined from the obtained 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 the signal from the CCD camera 5 is analyzed by 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 to obtain one of the horizontal stripe patterns of the cloth MA. Is moved to the same level as a specific position in the vertical direction of, such as a position where the color changes or a position where the shade changes. After that, the air cylinder 77 is driven to move the handle 6 to the front so that the handle 6 is attached to the cloth MA as shown in FIG.
Is stabbed (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 ( Process step N5). As a result, the cloth MA is completely pierced with the pattern matching needle 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 slip and the pattern matching accuracy is extremely high.

When the pattern matching operation of the cloth MA is completed, as shown in FIG. 11, each pattern matching needle 6 is moved to a predetermined cutting position. Then, the motor 60 is driven to rotate the rotary cutter 10 by 90 ° from the retracted position to change it 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 material MA is completed, the rotary cutter 10 is retracted, and the motor 73 in the pattern matching unit 7 is driven to lower the pattern matching needle 6 to a predetermined delivery position. The cloth material MA in the state is set at a position facing the pedestal 13 (FIG. 12).

The delivery operation of the cloth MA will be described with reference to the flowchart of FIG. First, the fabric receiving needle unit 116 is moved forward by the cylinder 117, and the fabric receiving needle 11 is pierced into the upper end portion of the fabric MA suspended from the pattern matching needle 6. Further, if the fabric receiving needle 11 and the push-pin 118 are moved forward by the cylinder 12,
As shown in FIG. 3, the push-pin 118 pushes the needle holder 79 on the side of the handle 6 to push the handle 6 into the fabric MA.
It acts so as to pull it out from the process (processing step N11 in FIG. 18). At this time, the push-push pin 118 moves the needle holder 7
Since 9 is pushed in, 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 dough MA is received, the pedestal rotating cylinder 141 causes the pedestal 13 to have an inclined posture rotated about 20 ° rearward from the vertical posture of the fabric receiving position as shown in FIG. As shown in FIG. 15, the cloth receiving unit 116 is retracted by the cylinder 117 in the inclined posture (processing step N13), and the apparatus is ready to receive the next cloth MA. By tilting the pedestal 13 rearward when receiving the cloth MA, it is possible to prevent the cloth MA from being dropped carelessly when the cloth MA is delivered, and moreover, there are many parts of the cloth MA due to its own weight. Since it is received by the receiving table 13, even if the load applied to the fabric receiving needle 11 is reduced and vibration is applied, the receiving needle 11 is not likely to be broken.

Then, the cradle rotating cylinder 141 returns the cradle 13 to the vertical position at the cloth receiving position (process step N14). Then, the same operation as described above is repeated until the predetermined number of the fabrics MA is reached (processing step N15), and when the predetermined number is reached (judgment step N16), the fabrics MA which are pattern-matched and cut into a predetermined size are obtained. 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 retract the vertical pedestal 13 while rotating it backward. 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 independently, the operation occupies a large space.
As described above, the space can be reduced by operating the cradle 13 so as to rotate and retreat in an interlocking relationship.

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.
Although A was cut, as shown in FIG. 19, with both the pattern matching needle 6 and the material receiving needle 11 pierced into the material MA, the material MA was cut by the rotary cutter 10 at a position between both needles 6 and 11. You may make it cut. In this case, the fabric M
Since the cut portion of A is held in both sides by the needles 6 and 11, the cutting action by the rotary cutter 10 can be performed smoothly and smoothly, and the cloth MA can be delivered more reliably.
