A device 4 that feeds the tape-shaped anti-slip material 3 made of a synthetic polymer material placed thereon, and a balent 1 that is moved by a conveyor device 2.
A pressing roller 5 is arranged near the surface of the pallet 1 and is movable up and down to press the anti-slip material 3 onto the surface of the pallet 1 as it passes through.
, a feed guide tube 6 that guides the anti-slip material 3 from the anti-slip material supply device 4 to the vicinity of the side of the pressure roller 5, and a heating device that heats both of the anti-slip material 3 to weld it to the surface of the pallet 1. It was mainly composed of 7.

In such a conventional surface treatment apparatus, in particular, the anti-slip material supply device 4 is equipped with a magazine N8 loaded with a fixed length of anti-slip material 3. A belt conveyor device 9 is arranged so that the anti-slip materials 3 dropped one by one from the lower part of the magazine device 8 are moved to the position of the feed roller lO arranged at the upper part of the feed guide tube 6 by the belt conveyor device 9. sent to. Then, the anti-slip material 3 is pulled out from above the heel conveyor device 9 by the feed roller 10 and the clamping roller 11 and fed into the feed guide tube 6.

(Problem to be Solved by the Invention) However, in the conventional anti-slip material supply device 4, each anti-slip material 3 is loaded from the magazine device 8 onto the heald conveyor device 9 at a predetermined position, that is, the feeding guide tube 6 is arranged. The problem is that it takes a very long time to convey the anti-slip material 3 to the specified position, and it is very difficult to accurately stop it at the specified position and feed it into the feeding guide tube 6. was there. Therefore, the magazine device 8 is installed above the feed guide tube 6, the anti-slip material 3 is dropped from the bottom of the magazine device 8 onto a suitable plate, and the material is pushed into the feed guide tube 6 by the feed roller 10. A method of retracting the material was considered, but even in this case, there was no guarantee that the feed roller 10 would reliably hold the anti-slip material 3, which caused the problem that the reliability of the feeding device could not be achieved.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for reliably feeding tapes one by one from the top to the bottom in a short period of time.

(Means for Solving the Problems) The tape supply device of the present invention includes a support rod that can reciprocate in the axial direction, a suction pad provided at the tip of the support rod, and a suction pad that communicates with the suction pad to create a negative inside. a tape pull-out device equipped with a vacuum supply source to generate pressure; a magazine device disposed above the tape pull-out device and storing a plurality of tapes therein; a magazine device disposed adjacent to the tape pull-out device; a clamping device having a clamping portion that clamps the tape when a suction buff (suction buff) comes into contact with one terminal surface of the lowermost tape in the magazine device to perform vacuum suction and pull out one end of the tape from the bottom of the magazine device; , a rotating body that supports both the tape pull-out device and the clamp device, and is installed such that the suction pad and clamp portion of each device can rotate in an arc.

(Function) According to the tape supply device of the present invention, one
When taking out and supplying a book tape, the support rod is first raised and the suction pad at its tip is brought into contact with the lower surface of one end of the tape at the lowest position in the magazine device. At the same time, a vacuum supply source is activated to create a negative pressure inside the adsorption band, and the tape is adsorbed. By lowering the support rod in this state, one end of the tape is pulled out from the bottom of the magazine device. Next, the tape with one end pulled out from the magazine device is firmly fixed by a clamp device, and then, when the clamp portion of this clamp device and the suction pad are rotated by a rotating body in a circular arc, The other end of the tape is extracted from the magazine device.

Then, the clamp section of the clamp device is released, the supply of negative pressure to the suction pad is stopped, and the suction pad is separated from the tape by movement of the support rod, so that the tape is fed in a predetermined direction.

(Embodiments) Hereinafter, the tape supply device of the present invention will be described in more detail with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows a tape supply device 20 according to an embodiment of the present invention.
It is shown. The tape supply device 20 of this embodiment is as follows:
This is used when welding a tape-shaped anti-slip material made of synthetic polymer material to the surface of a pallet, which is a resin molded product at the bottom, and when pulling out the anti-slip material from the magazine device and supplying it to the surface of the pallet. , "tape" therefore means a non-slip material. This tape supply device 20 includes a magazine device 22 that stores an appropriate number of tapes 21 in a loaded state, and the bottom of the magazine device 22 is open near one end and serves as a tape ejection port 22a.

Tape ejection port 2 at the bottom of this magazine device 22
Directly below 2a, a tape drawing device 23 is attached to a rotary body 24 and arranged. This tape drawing device 23
has a cylinder device 25 supported vertically with a piston rod 25a facing upward, and a suction pad 26 is attached to the end of the piston rod 25a of the cylinder device 25. One end of a negative pressure introduction pipe 27 is connected to this suction pad 26, and the other end of the n pressure introduction pipe 27 is connected to a vacuum supply source (not shown). Negative pressure is applied accordingly.

The rotating body 24 to which such a tape drawing device 23 is attached is further provided with a clamping device 28 arranged and attached in line with the tape drawing device 23. This clamping device 28 also includes a cylinder device 29 that is vertically supported with a piston rod 29a facing upward.
A clamp portion 30 is provided at the end of a. As shown in FIG.
The tape holder at the end of a is attached to the shaft 3 fixed to the side of the stand 30b.
It is fixedly connected to a sleeve 30d rotatably fitted to the sleeve 30c. One end of the presser plate 30e is fixed to this sleeve 30d, so that the sleeve 30d
By this rotation, the holding plate 30e is driven between a horizontal position where the tape receiver covers the upper surface of the stand 30b and an upright position where it is opened.

As shown in FIG. 1, one end of an arc-shaped tape holder 31 is fixed to the end of the stand 30b, and the other end is supported by a rim 32 attached to the rotating body 24. This tape holder 31 prevents the rear end of the tape 21 from hanging down when it is pulled out from the magazine device 22, and serves as a guide during Ij feeding.

Tape drawing device 23. The rotary body 24, which supports both the clamp device 28 and the tape holder 31, rotates around an appropriate position where the suction pad 26 of the tape pull-out device 23 and the clamp part 30 of the clamp device 28 move in an arc. It is installed rotatably. The driving means for rotating this rotating body 24 is constituted by a known means such as an electric motor and a cylinder device.

Next, the operation of the tape supply device 20 according to the embodiment described in -1 will be explained.

For example, when feeding the tape 21 in the magazine device 22 to the pallet surface treatment device (FIG. 4), the cylinder device 25 of the tape drawing device 23 is actuated and the piston rod
5a rises at high speed, and the suction pad 26 attached to its tip comes into close contact with the lower surface of the lowermost tape exposed to the tape outlet 22a at the bottom of the magazine device 22. At the same time, the vacuum supply source acts to bring the inside of the suction pad 26 to zero pressure, which causes the tape 2 to stick to the suction pad 26.
1 is adsorbed.

Next, the suction pant 26 is lowered by the action of the cylinder device 25 to a point where the tape receiver is approximately at the same level as the top surface of the stand 30b. By descending this suction bay (y)□ 26, one end side of the lowest tape 21 in the magazine device 22 or directly downward is pulled out from the tape ejection port 22a at the bottom of the tape 21, and a part of it is pulled out from the -L side of the stand 30b. located in, but
The other end of the tape 21 is still in the magazine device 22.

Therefore, -#j (!Il) of the tape 21 is pulled in the horizontal direction to pull it out, but since the other end of the tape 21 is under the weight of an appropriate number of tapes in the magazine device 22, the suction pad 26 It is not possible to apply a large pulling force in the lateral direction with the adsorption force.

Therefore, the clamp device 28 acts to mechanically fix the tape 2I to the tape receiver stand 30b.

That is, the piston 1 is activated by the operation of the two cylinder devices.
When the lever 29a is raised, the lever 30a rotates about the shaft 30c, and the sleeve 30d is accordingly rotated. As a result, the presser plate 30e fixed to the sleeve 30d
rotates, and the tape holder covers or closes the upper surface of the stand 30b, thereby clamping the tape 21.

In this state, the rotating body 24 is rotated, and as a result, the suction pad 26 and the clamp part 30 both move downward in an arc, and as a result, the other end of the tape 21 is removed from the bottom of the magazine device 22. One tape 21 is pulled out laterally from the opening 22a by overcoming the weight of the storage tape, and even though it is pulled out, it sequentially rides on the tape holder 31 and is placed on the arc-shaped sushi that is its movement path. Ru. The rotating body 24 was stopped when it came to a nearly horizontal position d as shown by the imaginary line (two-dot chain line) in FIG. One of the pair of feed rollers 10a10b moves and the tape 2
Pinch the ends of 1.

At the same time, the supply of negative pressure into the suction pad 26 is stopped and the suction is released, and the suction pad 26 is separated from the tape 21 by the action of the cylinder device 25. The clamp device 28 also clamps the tape 2 at the clamp section 30.
Release the grip of 1.

In synchronization with this, the pair of feed rollers 10a and 10b are driven, and the tape 21 is fed into the feed guide tube 6. At this time, the other end of the tape 21 is guided on the tape holder 31 and flows to the feeding guide tube 6 without coming off its path.

When one tape 21 is thus supplied to the surface treatment apparatus, the rotating body 24 returns to its original position and repeats the same operation again.

By the way, as described above, this tape supply device 20 pulls out one end of the lowest tape 21 directly below from the tape ejection opening 22a at the bottom of the magazine device 22 disposed directly above, and then uses the clamp device 28 to pull out that one end of the tape 21. By firmly grasping the side of the tape 21 and rotating the clamp device 28 by the rotating body 24, the other end of the tape 21 can be pulled out laterally from the tape ejection port 22a of the magazine device 22 by overcoming the weight of the loaded tape. Therefore, if an excessive weight is applied to the other end of the tape 21, it will not be possible to pull it out smoothly. For this reason, the magazine device 22 disposed directly above the tape supply device 20 does not contain too many tapes, and is replenished whenever the tape runs out.

That is, as shown in FIG.
A tape main magazine device 33 is installed on the side of the tape main magazine device 33, and a suction transfer device 34 provided on the top of the main magazine device 33 transfers the tapes 21 one by one from the top of the main magazine device 33 to each magazine device 22 of the tape supply device 20. They are supposed to be rationed.

Note that since there are usually a plurality of anti-slip materials welded to the surface of the pallet 7), a corresponding number of tape supply devices are naturally arranged in the horizontal direction.

Therefore, the suction transfer device 34 performs an operation of distributing the tapes 21 from the main magazine device 33 to each magazine device 22 one after another.

(Effects of the Invention) As explained above, according to the tape supply device of the present invention, it is possible to reliably supply the tapes housed in the magazine device one by one to a predetermined device in a short time. Supply reliability can be significantly improved.
