Abstract

PURPOSE:To efficiently open the end of a fabric when the cylindrical skirt part of a shirt is subjected to a skirt sewing, by effecting press-contact, horizontal movement, rotation and elevation from above a separating member to the uppermost one of stacked fabrics to separate the uppermost fabric. CONSTITUTION:In the case of that stacked fabrics 89 set on a fabric setting bed 88 which is elevatably arranged, are processed from the uppermost one of the stacked fabrics, needle cloth pieces 1 are lowered by actuating a cylinder from the positon A to the position B so that a needle cloth 1a is made into press-contact with the surface of the uppermost cylindrical fabtic. After the needle cloth pieces 1 are horizontally shifted toward the position C to move a fabric 86 in the same direction, a gripping piece 4 positioned between the left and right needle cloth pieces 1 is rotated from its horizontal position to its vertical position, and as well the needle cloth pieces 1 are also rotated to their vertical positions to the outer end 89a of the fabric is separated upward. Then, after the needle cloth pieces 1 is lifted up, a pair of rods 66, 70, and a pair of rods 67, 71 which are positioned in the horizontal position are inserted below the end 89a of the fabric, and as well are rotated to their vertical positions to open the end of the fabric.

It is like that.

Next, the operation of the present invention will be explained.

First, by operating the air cylinder 15, the piston 16
is pushed down, and the clothing piece 1. is rotatable through the lowering of the swing plate 20, slide plate 31, and slide plate 43, respectively.
1 descends from position A to position B as shown in Figure 6, and the clothing 1
A is pressed against the surface of the uppermost layer of the stacked fabric (laminated fabric) 89.

Then, through the operation of the air cylinder 29, the piston 3
0 is pulled in, and the slide piece 31. Guide 23. As the slide plate 43 and the rod 27 move forward, the opening 1 moves forward in the horizontal direction from position B to position C while the clothing piece 1 remains locked to the front side fabric of the fabric 89.

Then, through the operation of the air cylinder 25, the piston 2
6 is pushed out, and the rod 27 is pushed out to a position where the fixed piece 28 hits the stopper 44, and the stator 5 is pushed out through the connecting piece 6.
is rotated about the support shaft 9, and the grip plate 4 is rotated from a horizontal position to a vertical position as shown in FIG. Front fabric edge 8
9a is rotated while being locked, and one piece of the front fabric edge 89a is reliably peeled off as shown in FIG.

Next, as shown in FIG. 10, the piston 36 is pushed out by the operation of the air cylinder 35, and as the stator 34 retreats, the rotating piece 37 is rotated about the support shaft 47, and the peeled fabric edge 89a is held by the gripping plate 40. The edge 89a of the dough is scooped up and the proximity sensors 41 and 42 for detecting the thickness of the dough are used.
is pressed against the gripping plate 4 side, and if the thickness of the fabric is equal to one piece of fabric according to the fabric thickness detection, the following operation will be performed, and if it is detected that two pieces of fabric have been peeled off, the following operation will be performed. will be stopped.

When it is sensed that only one piece of fabric has been peeled off as described above, the piston 16 of the air cylinder 15 is retracted and the piece of clothing l located at the position shown in FIG.
The gripping plate 4, the fabric end 89a, and the rotating piece 37, which are raised to the position E in the state IE in which 9a is locked and are in the state shown in FIG.

Next, as shown in FIG. 1, with the slide pieces 50.51 positioned at positions S and S of the rail 48.49, the air cylinders 72.73 are operated to push out the pistons 74.75, respectively, and the posts 62.63 Rods 66, 70 due to retreat
, 67° and 71 remain parallel to each other on the same horizontal plane.
Ti! J/F1hr+/ノh'ff1Yτ19, LHI
IIVf-yt-&x±l#tyaiJh is located below the peeled fabric edge 89a, and then the air cylinder 5
4.55 is actuated, the piston 56.57 is retracted, the slide piece 50.51 moves to position T, and the rod 6
6, 70, 67, and 71 follow each other, and the rods 66, 67 reach both edges of the cylindrical fabric 89 as shown in FIG.
6.87 are pushed out, and the rods 70.71 are rotated almost perpendicularly toward the side edge of the fabric via the rotating pieces 68.69, and the cylindrical fabric end 89a is opened as shown in FIG. be done.

Then, by operating the air cylinder 35, the piston 3
6 is retracted, the rotating piece 37 returns to its original position, the piston 26 of the air cylinder 25 is further retracted, the upright clothing piece 11 returns to the horizontal state, and the piston of the air cylinder 29 30 is pushed out, the clothing piece l moves back and returns, and at this time, the fabric end 89a that was locked to the clothing la is released, and the clothing piece l moves back to the sixth position.
Return to initial position A in the figure. In addition, the opening-shaped fabric 8 is
It is gripped and conveyed by an appropriate gripping device.

As described above, the present invention is capable of more effectively peeling off, grasping, and conveying one piece of fabric by reliably peeling off one fabric on the front side of a large number of stacked cylindrical fabrics and opening the fabric. This is possible.
