Description

[Detailed explanation of the idea] The present invention relates to a fabric fold forming device.

When sewing clothes, it is necessary to fold the fabric in half, fold it in half, etc. In the past, the creation of folds in these fabrics was done entirely by hand, but in recent years it has been increasingly automated. However, in the conventional automatic crease forming apparatus, the folded portion of the fabric is pushed into a predetermined gap using a pushing plate, and the crease is formed using an iron press. In these devices, the fabric is pressed into a narrow gap by a pressing plate and then iron-pressed, resulting in unnecessary lines being formed at the crease forming area, which must be corrected in a subsequent process. In addition, with the conventional method, although it is possible to form a linear fold forming surface 2 on the fabric 1 as shown in FIG.
It was not easy to form the fold forming surface 2 in a curved shape or a meandering shape as shown in FIG.

The present invention was developed in consideration of the above points, and it is possible to form folds without forcing the fabric into a narrow gap using a pushing plate, and eliminate unnecessary lines in the fold formation area, making it easier to use in the subsequent process. No need to fix unnecessary lines,

In addition, at the rear of the apparatus main body 3, as shown in FIGS. 3 and 4, a saddle-shaped dough loading table 35 and a dough attachment/detachment device 6 are arranged, and The fabric loading/unloading device 6 is freely driven back and forth by a drive device 36, and the fabric 1 with creases formed by the iron press 5 is carried out to a fabric loading table 35 and successively stacked and stored.

The formation of folds in the fabric 1 using the apparatus configured as described above will be explained.

For example, when forming folds on both shoulders of fabric 1 such as clothes as shown in FIG.
Loosen the adjusting tools 12 to spread them out to a predetermined interval, set each at a predetermined angle, and fix them to the support beam 10 as shown by the dashed-dotted line in FIG. The positioning tool 7 is adjusted appropriately using the tool 19 and the claw portion protrusion amount adjusting tool 20, and the predetermined folded portion 9 of the dough 1 is positioned in the center of the ruler portion 16 and the claw portion 17, so that it can be gripped by the gripping device 4. Set up. Then, the predetermined fabric 1 is placed on the positioning tool 7.
When the device is operated to place the dough on the dough mounting portion 8 as shown in FIG. comes into contact with the fabric 1, and the attachment/detachment drive device 18 is activated to grip predetermined folded portions 9 on both shoulders of the fabric 1, respectively. Next, the lifting device 15 rises to a predetermined height and moves forward in the direction of the arrow, and the fabric 1 is gripped and conveyed by the gripping device 4 until it forms a hanging fold as shown by the dashed line in FIG. The forming surface 2 successively abuts on the inclined part 32 of the press fixing part 23 of the iron press 5, and the hanging crease forming surface 2 breaks and slides on the press fixing part 23,
As shown by the dashed line, the upper and lower fold forming surfaces 2 are folded over each other from the folded portion 9 and transported to a predetermined position of the press fixing portion 23. When the fold forming surface 2 is placed on the press fixing part 23, the intake pipe 29 which is being sucked by the exhaust pump 31
The on-off valve 30 is opened to adsorb and fix the crease forming surface part to the press fixing part 23, and the attachment/detachment drive device 18 of the gripping device 4 is expanded to place the fabric 1 on the press fixing part 23 and grip it. The device 4 is raised by a lifting device 15 and is driven back to its original position by a reciprocating drive device 14. Then, the pressing device 27 of the iron press 5 is activated to lower the press movable part 24, and the heating element 33 heated to a predetermined temperature appropriately presses the folded fold forming surface 2 to form a fold. It is. Since the press fixing part 23 is made of an elastic material and can be pressed elastically by the heating body 33, the fold forming surface 2 of the fabric 1 can form folds with good pleatability. When the fold is formed and the press movable part 24 is retracted upward, the on-off valve 30 is closed, and the discharge drive device 36 is activated to move the fabric attachment/detachment device 6 forward and remove the fabric 1 on the press fixed part 23. It is to be grasped and carried out to the dough loading table 35 at the rear. In this way, the predetermined dough 1 is sequentially folded and stacked on the dough stacking table 35.

As shown above, the folded part can be grasped and the folded surface can be folded over and iron-pressed, so creases can be formed beautifully without creating unnecessary lines on the folded surface unlike conventional methods, which will be unnecessary in the subsequent process. There is no need to correct lines with an iron press or the like. Further, as described above, even a curved fold forming surface can be easily formed, and folds other than linear folds can be formed as appropriate. Further, in this embodiment, the process from forming folds on the fabric to transporting the fabric can be performed automatically, and the fabrics can be stacked and stored in the carrying-out section, so that the fold forming work can be performed with extremely high production efficiency.

In addition, when forming a linear fold forming surface, it is sufficient to arrange the gripping devices in a straight line and positioning tools in a straight line, but it is possible to form a curved fold forming surface. When forming a surface, it can be done in the same way as above by replacing and attaching a gripping device with a predetermined curved ruler part and a claw part to the support beam, and it is possible to mechanically fold the fabric. It is possible to expand the range in which eyes can be formed.

In addition, for fabrics that are difficult to fold, such as polyester or linen mixed fabrics, the ruler and claws may be made of a material that is easy to grip the fabric, such as natural rubber or synthetic rubber, or may be formed into a comb-like shape. The surface may be serrated or uneven, or an elastic material such as magnetic rubber may be installed on the dough mounting portion as appropriate.
