Air cylinder for rack 2 after being locked
The rod of 4 contracts. Therefore, the shaft 20 rotates counterclockwise, and since the flange 25 and the ring member 28 are integrated by the steel ball 29, the ring member 28 also rotates counterclockwise together with the shaft 20. Therefore, the hook part 3
1 is pulled up, and the rear end thereof is attracted to the magnet piece 32a and locked by the stopper 32, whereby the shank 30 is vertically arranged. When the shank 30 is arranged in the vertical position, the concave portion 28a, the through hole 25c, and the upper portion of the guide groove 26a are arranged to face each other. Therefore, when the flange 25 further rotates counterclockwise, the ring member 2
8 does not rotate any more (because the rear end of the hook portion 31 is locked by the stopper 32), the steel ball 29 is transferred to the guide groove 26a. As a result, the engagement state between the flange 25 and the ring member 28 is released. And the flange 25 is formed by the guide groove 2
The steel ball 29 is guided by 6a and rotates counterclockwise with the shaft 20 up to the predetermined arrangement angle of the through hole 25c.

Thus, in this embodiment, the flange 25 extends from the one end portion 6a side of the apparatus main body 6 to the other end portion 6b side, and the position of the through hole 25c is gradually displaced as described above to the shaft 20. It is fixed. Therefore the shaft 20
When is rotated clockwise, first, the one end portion 6 of the device main body 6
When the shank 30 sequentially falls from the side of a to start hooking, and when the shaft 20 rotates counterclockwise, the shank 30 sequentially stands up from the side of the other end 6b of the apparatus body 6. When the flange 25 is arranged on the shaft 20 in this manner, both side edges of the futon cloth 1 can be sequentially hooked from the end of the apparatus body 6, so that the hooking operation can be made smooth and reliable.

After the lower cloth is hooked on the hook 4a of the comforter frame 4 in this manner, the worker places the futon cotton 5 on the lower cloth. After that, the rod of the air cylinder as the elevating means 7b is extended, and the upper plate 7a is lowered to the reference reference height H and arranged. Then, in the apparatus of the present invention, the upper cloth is stretched on the bedding tension frame 4 in the same procedure as the above-mentioned operation of stretching the lower cloth. In the case of the present invention, these operations are preferably performed by the controller, but may be individually operated by the switch means, for example.

In the above process, the cutter 18 may be formed, for example, so as to pull one blade in the width direction of the futon cloth 1, and is not limited to the above example.

Further, the hooking mechanism 11 described above is not limited to the above example in the present invention.
