Description

[Detailed description of the invention] [Industrial field of application] Water device 1'? The present invention relates to the automation and unmanned operation of coil insulation work, that is, the taping work of winding tape around a coil, and particularly relates to an automatic cutting and pasting device for adhesive 7η tape suitable for preventing the tape from tangling when taping is completed.

[Conventional technology]

In the conventional apparatus, as described in Japanese Unexamined Patent Publication No. 52-1471!15, one end of a tape cut to a fixed length is pasted on a rotating disk. However, in this state, the other tape end curls. In other words, since adhesive is applied to one side, no consideration has been taken to prevent the end of the tape from curling due to temperature and time.Furthermore, the operation of removing the tape after cutting and pasting it onto the material to be pasted is done manually. was assumed, and there was no consideration of automatic pasting.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into consideration the fact that the end of the adhesive tape curls, resulting in a dimensional error when cutting to a fixed size.

There were problems with workability and reliability of pasting. moreover,
Since the mechanism for taking out the adhesive tape after cutting the tape and applying it to the material to be applied is a manual operation, there was a problem in terms of the self-applying mechanism.

An object of the present invention is to provide a device that automates the cutting and pasting of adhesive tapes to a fixed size with high reliability.

[Means to solve the problem]

The above purpose is to create a polygonal shape that has a shaft on a movable base with a groove into which a cutting blade can be inserted, which can be rotated while wrapping an adhesive tape around the shaft as a guide, and which also has a vacuum suction function. Cutting units 1 to 1 which hold and cut a disk having a surface and an adhesive tape are synchronously rotated at a predetermined angle to cut to a fixed size. At that time, by vacuum suctioning the adhesive tape on one side of the vacuum system, it is possible to eliminate the phenomenon of stickiness, curling and entrainment of the end of the n-tape. Further, in the pasting operation, automatic cutting and pasting can be achieved by pressing the movable base against the material to be pasted and then turning off the other vacuum system.

[Effect]

The cutting mechanism of this device consists of a disc with a polygonal surface wrapped around the non-adhesive side of adhesive tape and a 9J attached to the arm.
Press the adhesive tape between the cutting devices and cut. Since the index cylinder is rotated by a predetermined angle in this state, there are no cutting errors, feed errors, or cutting length errors during cutting. Furthermore, a release material is provided on the presser head of the cutting device to prevent the adhesive tape from sticking to the pressing head when the cutting head is returned.

On the other hand, in order to prevent the adhesive tape that has been cut and wound into a polygonal disc from falling off and the end of the adhesive tape from curling, vacuum suction is performed, but the vacuum system is separated into two independent systems.
It's sinking. In other words, - the vacuum system of force is applied to one side of the polygonal disk where the adhesive tape is applied to the material to be applied, and the other vacuum system is cut and wrapped around the other side of the polygonal disk. The adhesive tape is vacuum-adsorbed. Thereby,
In particular, when applying an adhesive tape to a material to be applied, the reliability of application is improved by blowing out compressed air after releasing the vacuum suction.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

11 of the present invention? The l configuration is a shaft 2 fixed to a moving base 1.
A disc 3 with a hexagonal surface and a cutting blade 4 whose rotation center is
．． A cutting arm 6 incorporating an adhesive tape presser 5 is provided. The movable base 1 is fixed to a fixed plate 9 via a linear rail 7 and a bearing 8, and is movable by a cylinder 11. Furthermore, the hexagonal disk 3 has 1 and 12 at the intersections of the hexagons, and vacuum suction holes 13 on the surface.
．． Cushion materials 14 are installed on every six sides, and the cushion materials are equipped with vacuum suction boats 15. Further, the hexagonal disk has a positioning plunger 16 and
An axial vacuum seal 17 is provided. On the other hand, the cutting arm 6 has a built-in bearing 18 and a rotating pulley 1.
9. The timing bell 1 is connected to a timing pulley 22 provided on an index cylinder 21 via 20.

Further, the shaft 2 is provided with separate vacuum supply holes 23 and 24, one of which faces the material to be pasted 25, and the other of which is provided with the shaft c3 to vacuum adsorb the cut adhesive 1 tapes 2G and 27. A passage groove 28 is provided in a part of the circumferential direction to communicate with the vacuum supply hole 24.

Next, automatic sizing cutting and pasting operations will be explained.

An adhesive tape 27 is wound from a tape bobbin 29 so that its non-adhesive surface contacts the hexagonal disk 3. The cutting cylinder 10 provided on the cutting arm 6 presses the adhesive tape 27 against the presser foot 5 and the hexagonal disk. Due to the pressing action, the force of the cutting cylinder 100 overcomes the spring force of the 3° spring, and the cutting blade 5 is moved into the groove 12.
The adhesive tape 27 is cut by extruding it. In this state, the timing pulley 22. The cutting arm 6 and the hexagonal disk 3 are synchronously rotated and indexed by a predetermined angle (60 degrees) through the timing bell I-20 and the timing pulley 19. Thereafter, the cutting cylinder 30 and the cutting arts G are returned to their original positions. At this time, the presser foot 5 and the adhesive tape 27 are completely peeled off to prevent the adhesive tape from slipping and being pulled back. A release material 31 is provided on the surface of 5. Further, the hexagonal disk 3 is configured to be fixed at a fixed position by a plunger 16.

By performing the above-mentioned J process two or three times, the adhesive tape 27 that has been cut to a fixed size and sucked by the vacuum ports 23, 24, 13, and 15 is indexed to a position facing the material 25 to be pasted. Thereafter, the linear rail 7 is connected to the moving base 1 through the bearing 8 by the cylinder 11. By moving the hexagonal disc 3 provided on the shaft 1 toward the tab of the material to be applied and pressing it, the adhesive tape 27 cut to a fixed size is applied to the material to be applied 25. At this time, the cushion material 14 is made to follow the surface shape of the material to be pasted 25, thereby improving the reliability of pasting. moreover.

After pasting, when the vacuum suction is turned off and the hexagonal disk is returned, compressed air is sent into the vacuum bow 1-23, thereby further improving the reliability of pasting. In addition, since the vacuum system has two independent circuits, the ends of the adhesive tape 27, which has been cut to size and vacuum-adsorbed to the hexagonal disk, will not curl.
Moreover, regardless of the pasting operation! p11 production is now possible,
The adhesive tape 27 did not fall off due to its own weight.

〔Effect of the invention〕

According to the present invention, automatic sizing cutting and pasting of adhesive tape can be performed with high accuracy and reliability, and the device can be made with a simple structure and miniaturized, so that it can be easily installed in line equipment, automated equipment, and , can be incorporated into packaging equipment.
