Abstract

PURPOSE:To surely separate labels one by one by blowing air into between the front part labels among the labels which are accommodated in superposed state into a label magazine, and separating both the edge parts of the labels from a hook. CONSTITUTION:A hand 1 is retreated, applying each negative pressure on adsorbing pads 8a, 8b, and 8c and blowing air from an air blow-out port. During the retreat operation, the adsorbing pads 8a, 8b and 8c are advanced. At the same time, a label 13 is successively separated from a hook 12a towards the center direction, since the center adsorbing pad 8b is set higher than the left and right adsorbing pads 8a and 8c. Then, retreat is carried out furthermore, and the adsorption for the label is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method and apparatus for separating polymeric thin films stored in a magazine one by one using a suction pad.

(Conventional Wave #I> Conventionally, as shown in FIG. 6, labels 21 are stacked and stored in a label magazine 20, and are biased from behind by a spring 22 and locked to a claw on the front edge of the label magazine 20. A plurality of suction pads 24 fixed at the same height are pressed on the hand 23 of the front label 2o at the same time and suction is applied to the label 1.
A device for attaching sheets to a board and transporting them to a predetermined position is known.

(Problems to be Solved by the Invention) However, in most of the above conventional techniques, the label is charged with moisture or static electricity. Therefore, each label is difficult to peel off. Therefore,
If you try to pick up the first label stacked and stored in the label magazine and take it out from the label magazine, you may end up taking out two or more labels, or a part of the first label may be removed as shown in Figure 6. There was a problem that the label protruded from the label magazine, making it impossible to reliably separate each label.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems. (1) Both ends of the thin film material stored in a polymerized manner in the magazine are locked to the claws at the front end of the magazine, and the suction pad in the center part is fixed. A method for separating a polymerized thin film, in which the front surface of the thin film is pressed, the thin film near the locking part is attracted and pulled to be removed from the locking part, and then the central part of the thin film is also pulled and separated. ■Fix multiple suction pads to the plate, make the height of the suction pad in the center higher than the height of the suction pads at both ends, and inject toward the inside of the thin foil at the front of the thin foil that is stacked and stored in the magazine. An air outlet is formed in the magazine, the plate is arranged so as to be able to slide back and forth, and a central suction pad is pressed at the center of the front thin sheet, and both end suction pads are pressed at both ends. Features a separation device.

Hereinafter, a detailed explanation will be given based on one embodiment of the present invention shown in FIGS. 1 to 5. An air cylinder 2 is fixed to the robot hand 1, and a rod 3 of the air cylinder 2
A board 4 for attaching a suction pad is fixed to the tip, a label suppressing plate 6 is fixed to the front end of a frame 5 fixed to the board 4, and a plate 7 is fixed in the middle. Three suction pads 8a, 8b, and 8c are attached to the plate 7, from the center pad 8b to the pads 8a at both ends.

Lower the height of 8c and use suction pads 8a and 8b.

8c is a sleeve 9a fixed to the plate 7.

The suction pads 8a, 8b, 9b, 9c can be slid inside, and are always urged forward by an elastic member disposed inside the sleeve.
The tip 8c protrudes from the holes 6a, 6b, and 6c of the label pressing plate 6. 10a.

Job is a guide rod fixed to the board 4, and the hand 1
The sleeves lla and llb can be slid within the sleeves lla and llb fixed to the sleeves lla and llb. 12 is a label magazine which stores a large number of labels 13 in a stack, and has a label pressing plate 14 in contact with the rear thereof;
The label 13 is pressed forward by an elastic member and the front end of the label 13 is locked to claws 12a at both ends of the front edge of the label magazine 12. One label 13 is stored in the front part of the label magazine 12.
An air outlet 15 is formed to inject air into the front label.

Next, the effect will be explained. The robot hand 1 is positioned on the label magazine 12. Next, the air cylinder 2 is operated to move the substrate 4 forward.

The suction pads 8a, 8b, 8c come into contact with the label 9, the suction pads retreat, and the label pressing plate 6 and the suction pads 8a, 8b
, 8c are flush with each other, and the label pressing plate 6 comes into contact with the label 13. The substrate 4 is further advanced.

Next, while applying negative pressure to the suction pads 8a, 8b, and 8c,
Further, the hand 1 is moved backward while blowing air from the air outlet 15. While doing this backward movement, each suction pad 8a, 8b.

8c moves forward. At the same time, since the center suction pad 8b is set higher than the left and right suction pads 8a and 8c, the labels 13 are successively separated from the claw 12a toward the center. It is further retreated and label adsorption is completed.

Although this embodiment shows the case where the device is installed horizontally, it may also be installed vertically (in the vertical direction).

(Effects) According to the present invention, ■ Both ends of the thin film body stacked and stored in the magazine are locked to the claws at the front end of the magazine, and while the front side of the thin film body is pressed by the suction pad in the center, the thin film body near the locking part is A method for separating a polymeric thin film by adsorbing the thin film and pulling it to release it from a locking part, and then pulling the center part of the thin film to separate it. ■Fix multiple suction pads to the plate,
The height of the suction pad at the center is made higher than the height of the suction pads at both ends, and an air outlet is formed in the magazine to inject air into the front thin sheet of the thin sheet that is stacked and stored in the magazine. The gist of this is a polymeric thin film separation device that is arranged so as to be able to slide back and forth, and has a central suction pad in the center of the front thin film and pressure-contacted end suction pads on both ends. Air is blown between the front labels of the stacked and stored labels, and both ends of the label are separated from the claws, so that the labels can be reliably separated one by one.
