The operation of the hydraulic cylinder 79 causes the swinging arms 77 to swing in opposite directions, and the pinch rolls 75 move between a closed position where they are pressed against each other and an open position where they are spaced apart.

The band cutting device 13 includes a device frame 92 in which a pair of left-right sliding guide members 91 are provided on the upper and lower sides, and upper and lower horizontal sliding rods 93 in the left-right direction supported by the upper and lower guide members 91, respectively. A vertically movable rail 95 is stopped at the right end of the sliding rod 93 and is provided with a vertical guide member 94, and an inverted V-shaped cutter 97 is attached to a sliding guide member 96 that moves along the guide member 94. and a hydraulic cylinder 98 which is attached upward to the lower end of the movable rail 95 and has a rod connected to the cutter 97.

A fluid pressure cylinder 10 is located mid-height of the device frame 92.
1 is installed facing right, and its rod is attached to the movable rail 95.
is connected to. Two horizontal guide tubes 102 are attached near the upper end of the movable rail 95 and below this. A movable rod 103 is fitted into each guide tube 102. A vertical pressing plate 104 is fixed at the right protruding end of all the movable rods t03, and a stopper 105 is provided at the left protruding end. Guide cylinder 102 and press plate 1
A compression spring 10B is interposed between the springs 04 and 04. Pressing plate 1
04 is provided with a vertical slit 107 into which the tip of the cutter 97 is inserted. Further, a limit switch 108 for detecting the left limit position of the press plate 104 is attached to the movable rail 95. Furthermore, the pressing plate 10
4, an article positioning member 109 is provided on the movable rail 95.

The cutter 97 is raised and lowered by the operation of the upward hydraulic cylinder 98. On the other hand, due to the operation of the rightward fluid pressure cylinder 101, the movable rail 95 is reciprocated in the left-right direction.

When the article W is carried into the processing station, the movable table 24 is moved to the left and the movable rail 95 is moved to the right. When the movable table 24 approaches the article W and moves a predetermined distance after the contact piece 34 contacts the article W, the movable rod 33 is moved to the right, and the limit switch 37 detects this. , the movable table 24 stops based on the detection signal. On the other hand, the movable rail 9
5 approaches the article W and the movable rail 95 moves a predetermined distance after the press plate 104 comes into contact with the article W, the movable rod 103 is moved to the left, this is detected by the limit switch 108, and the detection signal Movable rail based on 9
5 stops. In this way, when the movable table 24 and the movable rail 95 are each stopped, the belt 48 is moved. Then, the chuck 49 along with the belt 48
moves, and when the chuck 49 reaches band B on its upward movement path, the fixed claw 6 of the chuck 49
The band B is chucked by the chuck 49 so that the band B is sandwiched between the movable claw 7 and the movable claw 69. Band B
is chucked, the tension of the belt 48 increases, which causes the swing frame 43 to rotate downward by a certain angle and the tension rod 54 to move downward, causing the drive pulley 44 to idle and cause the belt 48 to move. stops.

When the tension rod 54 moves downward, the limit switch 57 detects this and lowers the cutter 97 to cut the band B based on the detection signal. Also, before and after cutting the band B, both pinch rolls 75 are placed in the open position. When the band B is cut, the tension of the belt 48 returns to its original state, the swing frame 43 moves upward, and the belt 48 is moved again. Then, the chuck 49 that chucked hand B is attached to belt 4.
When the chuck 49 eventually reaches the chucking release member 58 in the middle of its downward movement path, the pushing member 71 of the chuck 49 rides on the contact surface 59 of the chucking release member 58. The movable claw 69 is pushed, and as a result, the chucking of the band B is released.

Around this time, when both pinch rolls 75 are brought to the closed position and both pinch rolls 75 are driven, the band B is sent downward by both pinch rolls 75 and received by the band storage box 28 .

Band B fed by the pinch rolls 75 is folded exactly in half, and the amount of feed may be exactly half the length of band B. This is because the chucking position and the cutting position are set at two positions that divide the band B into two parts of equal length.

Effects of the Invention According to this invention, since the chucking position and the cutting position are set at two positions that divide the band into two parts, the movement of the chuck causes the band to move with a length greater than the chuck movement distance. Therefore, compared to the conventional device described at the beginning, the device can be made smaller and the band can be cut in a shorter time.
