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

First, the piston 16 is pushed down by the operation of the air cylinder 15, and the rotatable clothing plates 1, 1 are placed in the position as shown in FIG. It descends from A to position B, and the clothing 1a is pressed against the surface of the uppermost layer of the stacked fabric (laminated fabric) 89.

Next, the piston 30 was retracted through the operation of the air cylinder 29, and the slide piece 31, guide 23, slide plate 43, and rod 27 moved forward, so that the clothing plate 1 was locked to the front fabric of the fabric 89. The same piece 1 moves forward in the horizontal direction from position B to position C.

Next, the piston 26 is pushed out through the operation of the air cylinder 25, the rod 27 is pushed out to the position where the fixed piece 28 hits the stopper 44, and the stator 5 rotates about the support shaft 9 via the connecting piece 6. Then, the grip plate 4 rotates from the horizontal to the vertical position as shown in FIG. 8, and at the same time, the clothing plate 1 moves from the horizontal position to the almost vertical direction while retaining the cylindrical front fabric edge 89a. It is rotated to ensure that one piece of the front fabric edge 89a is peeled off as shown in FIG.

Next, as shown in Fig. 10, the air cylinder 35
The piston 36 is pushed out by the operation of the stator 3
4 retreats, the rotating piece 37 is rotated about the support shaft 47 and peeled off, and the dough edge 89a is scooped up by the gripping plate 40, and the dough edge 89a is scooped up by the gripping plate by the proximity sensors 41 and 42 for detecting the thickness of the dough. If the fabric is pressed against the 4th side and the thickness of the fabric is equal to 1 piece of fabric by sensing the fabric thickness, the following operation will be performed, and the fabric will become 2 pieces.
When it is sensed that the sheet has been peeled off, the following operations are stopped.

When it is detected 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 clothing plate 1 at position D locks the edge 89a of the fabric as shown in FIG. The grip plate 4, cloth plate 89a, and rotating piece 37, which have been raised to position E and are in the state shown in FIG.

Next, as shown in FIG. 1, with the slide pieces 50, 51 located at positions S, S of the rails 48, 49, the air cylinders 72, 73 are operated to push out the pistons 74, 75, respectively, and the columns 62, 63
11, the rods 66, 70, 67, and 71 move horizontally from position U to position V as shown in FIG. 54, 55 are actuated and the pistons 56, 5
7 is pulled in, and the slide pieces 50 and 51 are at position T.
The rods 66, 70, 67, and 71 follow each other, and the rods 66, 6 move as shown in FIG.
7 reaches both side edges of the cylindrical fabric 89, then the air cylinders 80, 81 are activated and the pistons 86,
87 are pushed out, and the rods 70 and 71 are rotated approximately perpendicularly toward the side edge of the fabric via the rotating pieces 68 and 69, and the cylindrical fabric edge 89a is opened as shown in FIG. .

Next, by the operation of the air cylinder 35, the piston 36 is retracted, the rotating piece 37 returns to its original position, and the piston 26 of the air cylinder 25 is further retracted, so that the 11th upright cloth piece is placed in a horizontal state. Returned and further air cylinder 29
As the piston 30 is pushed out, the clothing plate 1 moves back and returns, and at this time, the fabric end 89a that was locked to the clothing 1a is released, and the clothing plate 1 returns to the initial position A in FIG. do. In addition, the opening-shaped fabric 8
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.
