Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a device for conveying soft woven fabric pieces used in a manufacturing process for manufacturing clothes from woven fabric.

(Prior art and its problems) In the manufacturing process of manufacturing textile products such as clothes from woven cloth, a step of conveying and supplying the woven cloth piece to a machine such as a sewing machine is required. Due to the lack of mechanical means for transporting and feeding through the machine, the operator has to perform this operation manually, which not only increases the work steps of the worker but also saves the worker considerable effort. You will have to request.

The present invention has been made in view of the above-mentioned points, and a soft woven fabric piece is effectively provided to one or more processing locations where the woven fabric pieces are processed, or via one or more processing locations. An object of the present invention is to provide a conveying device for a soft woven fabric piece to be conveyed.

(Summary of the Invention) A conveying device for a soft woven cloth piece according to the present invention has a flat low friction upper surface, a transfer member for supporting the soft woven cloth piece in a flat state on the low friction upper surface, and a lowering member for the transfer member. A support device for supporting movement in both directions between a first position and a second position in a direction orthogonal to the edge of the friction upper surface and a transfer member having a flat low friction upper surface The receiving member located below the transfer member when in the position is frictionally engaged with the exposed surface of the soft woven fabric piece supported by the low friction upper surface of the receiving member in the second position, and the transfer member is in the second position. And a friction engagement device for moving the soft woven fabric piece to another processing position on the low friction upper surface of the receiving member at a certain time, and the friction engagement device comprises:
The soft woven fabric piece is arranged to engage the soft woven fabric piece along at least one edge of the soft woven fabric piece such that the soft woven fabric piece projects beyond the friction engagement device, and the transfer member is in the second position. , Moving up and down with respect to the low friction upper surface of the receiving member so as to engage with the soft woven fabric piece, and the low friction upper surface of the friction engagement device and the transfer member are provided when the soft woven fabric piece is frictionally engaged. And when the transfer member returns from the second position to the first position, the soft woven fabric piece is pulled out from the transfer member over the edge of the transfer member and supported in a flat state on the low friction upper surface of the receiving member. And

The friction engagement device may be selectively movable relative to the low friction upper surface of the receiving member to engage the fabric piece when the transfer member is in the second position. The friction engagement device engages the woven fabric piece at a plurality of selected spaced positions to maintain the woven fabric piece in a flat condition after the transfer member is withdrawn. The spaced positions are positions along one or more, preferably two opposing edges of the woven fabric piece.

The friction engagement device has a plate that is similar in shape to the woven piece but smaller than the woven piece, the plate having a strip of high friction material about which the woven piece engages.

The flat low friction upper surface of the transfer member can be a polished metal surface. Also, the low friction upper surface portion of the transfer member is
The thickness is preferably of the order of a few millimeters, for example a few millimeters, so that when the transfer member is withdrawn, the woven fabric piece descends a small distance above the receiving member. The frictional engagement device is resiliently or flexibly arranged so that engagement to the piece of fabric is maintained as support of the piece of fabric is maintained as it is transferred from the transfer member to the receiving member. .

The transfer member is formed of a carriage equipped with wheels and reciprocally mounted on the air actuating means and a thin abrasive metal blade mounted on the carriage.

(Example) Hereinafter, the Example of this invention is described using drawing.

In FIG. 1, reference numeral 6 indicates a woven fabric piece. This woven piece 6
Are fed to the low friction upper surface of the plate 7 by a suitable device (not shown). The plate 7 is preferably made of metal, for example aluminum. Plate 7
Reduces the friction appropriately by polishing the upper surface. The plate 7 is supported by a carriage (not shown) having a plurality of wheels 10 that move on a pair of rails 11, 11. The pair of rails 11, 11 extend to a position below the bench 8 and feed the woven fabric piece 6 to various processing devices along the bench 8. The lower side of the bench 8 is a position where the plate 7 (processing position 2), that is, the woven fabric piece 6 is placed directly below the friction gripping device 9 (the friction gripping device 9 goes down above the position of the woven fabric piece 6). The woven fabric piece 6 is further moved. The bench 8 has a pair of recesses (not shown) into which the wheels 10 of the carriage are placed. The upper surface of the bench 8 also has a relatively small friction surface. The friction surface of the bench 8 is formed of a conventional ground metal or a ground composite sheet laminate material. When the plate 7 reaches the processing position 2, the plate 7 rides on the flat surface of the bench 8 and slides on it.

The carriage supporting the plate 7 is mounted and operated in a suitable device for movement between the processing position 1 and the processing position 2. The carriage is moved by an air operated pistonless cylinder. The air-operated pistonless cylinder controls the plate 7 so as to reciprocate between the processing position 1 and the processing position 2 in accordance with the operation of other members of the apparatus.

The woven fabric piece 6 is placed on the plate 7 by any suitable device, but it is also possible to place two superposed woven fabric pieces 6 on the plate 7. The plate 7 is then advanced from machining position 1 to machining position 2 by the action of an air-actuated pistonless cylinder. This plate 7 is the processing position 2
When stopped at, the friction gripping device 9 (shown in FIGS. 3a to 3d) descends above the woven fabric piece 6.

The gripping device 9 is a pair of clamps attached to the arm 13.
Moved up and down by 12,12. Both the clamp 12 and the arm 13 are gripped, released, and moved up and down by an air-operated mechanism attached to the film 15. The clamp 12 operates in cooperation with the pin 15 to grip the gripping device 9 (see Figures 3a to 3d).

A conveyor device 16 is supported by the frame 15.
This conveyor device 16 moves a plurality of gripping devices 9 to a clamp 12 which can be lowered to the woven fabric piece 6 at the processing position 2.

FIG. 3a shows the position on the woven fabric piece 6 of the gripping device 9 before engaging the clamp 12. FIGS. 3b and 3c show the gripping device 9 clamped in the clamp 12 before it is lowered onto the fabric piece 6. FIG. 3d shows the gripping device 9 engaged with the woven fabric piece 6 supported on the bench 8 after it has been lowered.

The gripping device 9 has a surface which engages the woven fabric piece in a shape selected for only frictional contact with the woven fabric piece 6. Grasping device 9
The contour shape of is a shape that follows the contour of the woven cloth piece only in a relatively small portion of the woven cloth piece 6 located outside the contact area of the gripping device 9 (Fig. 3d). The required degree of frictional grip between the gripping device 9 and the piece of woven fabric 6 is achieved by coating or coating the faces of the gripping device with friction material to obtain the desired degree of frictional gripping. The friction material is a sheet-like abrasive material such as emery paper.

The degree of frictional grip between the friction material and the piece of fabric is determined by the action of an air-actuated cylinder which is connected to the plate 7 and moves the plate 7 from the working position 2 to the working position 1. The size is such that the woven fabric piece 6 slides out from the gradual movement of the woven fabric piece 6 toward the bench 8 and is completely supported by the bench 8. The plate 7 returns to the processing position 1 by the action of the air-actuated cylinder and is positioned so as to receive another woven fabric piece 6.

The gripping device 9 can move the woven fabric piece 6 along the moving path of the gripping device 9 by continuing to contact the woven fabric piece 6 and moving it along the bench 8 in an appropriate manner.

The transfer member is suitable for moving the woven fabric piece through the sewing machine head and performing a sewing operation along the contour shape of the woven fabric piece.
