Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a tape winding device for winding a tape around an object to be wound.

(Prior Art) For example, when fixing insulating paper to an iron core, it is done by winding an adhesive tape around the core to which the insulating paper is attached. Traditionally, winding of this tape was done by hand, and the procedure involved cutting the tape to a predetermined length and wrapping the cut tape around the core of the transformer over insulating paper. .

(Problem to be solved by the invention) However, the work of manually winding the tape is troublesome and time-consuming, and the tape tends to loosen and wrinkle when it is pasted, and the coil is not attached afterwards. There was a problem in that it became difficult to wind.

The present invention has been made in view of the above-mentioned circumstances.The purpose of the present invention is to be able to automatically wind a tape around an object to be wound, and also to be able to wrap and stick the tape while applying tension to it, thereby preventing wrinkles. An object of the present invention is to provide a tape winding device that can prevent this from occurring.

[Structure of the Invention] (Means for Solving the Problems) The tape winding device of the present invention is provided with a pedestal for receiving the leading end of a tape pulled out from a tape supply source with the adhesive surface facing outward, and A cutter is provided at one end, and a gripping device is provided for gripping the object around which the tape is to be wound, and by moving this gripping device, the object to be wound is pressed against the receiving stand and the tape is removed. a first moving means for adhering the tip of the tape to the object to be wound, and rotating the gripping device to wind and tie the tape to the object to be wound while pulling out the tape from the tape supply source; A driving means is provided, and a second moving means is provided for moving the pedestal together with the cutter to position a portion of the tape near the end of winding on the object to be opposed to the cutter, and moving the gripping device. The invention is characterized in that a third moving means is provided for causing a cutter to cut a portion of the tape near the end of winding on the object to be wound.

(Operation) The tape is automatically wound and affixed to the object to be wound by rotating the object to be wound by the rotation drive means. At this time, the tape is wound around the object while being pulled out from the tape supply source, but tension is applied to the tape due to the pull-out resistance received from the tape supply source, so that the tape does not loosen.

(Example) Hereinafter, an example in which the present invention is applied to a case where an insulating paper is fixed by winding a tape around an iron core will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a box-shaped vertical support body attached to a base (not shown), and inside thereof, as shown in FIG. ing. 4 and 5 are air cylinders for vertical movement connected back to back, and these are arranged inside the vertical support 1, and the rod 4a of the lower air cylinder 4
is fixed to the bottom surface of the vertical support 1, and the rod 5a of the upper air cylinder 5 is fixed to the lower part of the elevating member 2, so that the elevating member 2 is moved up and down by the forward and backward movement of both rods 4a and 5a. It has become. 6 is a low actuator attached to the front part of the elevating member 2, and the base plate 8 of the gripping device 7 is attached to the rotating shaft 6a of this actuator. This gripping device 7 is constructed by attaching a suppression plate 10 facing a protruding piece 8a at one end of the substrate 8 to a rod 9a of a suppression air cylinder 9 attached to a substrate 8, and overlapping an insulating paper 11. When the iron core 12 as an object to be wound is sent by a transfer device (not shown), the rod 9a moves forward and pushes one end of the iron core 12 together with the insulating paper between the pressing plate 10 and the protruding piece 8a. It is designed to be held (pinched) between the two.

On the other hand, in FIG. 1, reference numeral 13 is a U-shaped horizontal support mounted on a base (not shown) to the left of the vertical support 1, and as shown in FIG. A moving air cylinder 14 is supported by a guide bar 15 so as to be movable in the left-right direction. The rod 14a of the left-right moving air cylinder 14 is fixed to the right side of the lateral support 13, and the main body 14b of the left-right moving air cylinder 14 moves in the left-right direction by the forward and backward movement of the rod 14a. ing. Reference numeral 16 denotes a support plate attached to the front side of the main body 14b of the left-right moving air cylinder 14, and a reel support part 17 is protruded from the upper left side of this support plate, and a tape 18 is wound around the reel support part 17. A reel 19 serving as a supply source is rotatably supported. Reference numeral 2o denotes a substantially inverted mounting piece attached to the front side of the strip portion 16a that protrudes to the right at the lower right portion of the support plate 16, and a pedestal 21 is mounted on the horizontal piece portion 2Oa. This pedestal 21 is supported by a compression coil spring 22.
The vertical piece 20b of the mounting piece 2o is pushed up to a position where it meets the upper end surface of the vertical piece 20b. A cutter 23 is fixed to the upper part of the vertical piece 20b of the mounting piece 2o, and has a sawtooth cutting blade, and is located on the right end side, which is one end side of the receiving table 21. Then, the tape 18 is pulled out from the reel 19 and passed through two rollers 2 supported by the support plate 16.

Reference numeral 26 denotes a pressure contact plate made of a leaf spring attached to the right side of the vertical piece 20b of the mounting piece 20, which protrudes downward from the vertical piece 20b, and its lower part is inclined so as to protrude to the right in the middle. It is formed in the portion 26a.

Next, the operation of the above configuration will be explained.

Now, as shown in Fig. 1, the air cylinder 4 for moving up and down the rain
and 5, the rods 4a and 5a are in an advanced state,
It is assumed that the gripping device 7 is at the highest position, the rod 14a of the air cylinder 14 for left and right movement is in a retracted state, and the pedestal 21 is positioned below the gripping device 7. In this state, when one end of the iron core 12 with the insulating paper 11 attached thereto is sent between the protruding piece 8a of the substrate 8 of the gripping device 7 and the pressing plate 10 by a transfer device (not shown), the suppression air cylinder The rod 9a of No. 9 moves forward, and as shown in FIGS. 1 and 4, one end of the iron core 12 is held together with the insulating paper 11 between the pressing plate 10 and the protruding piece 8a. When the iron core 12 is gripped by the gripping device 7 in this manner, the transfer device (not shown) returns to its original position, and the rod 4a of the lower vertical movement air cylinder 4 as the first moving means moves backward. , the elevating member 2 and thus the gripping device 7 are lowered via the upper air cylinder 5 for vertical movement.

Then, the iron core 12 comes into contact with the pedestal 21 via the tape 18, and the pedestal 21 is pushed down against the elastic force of the compression coil spring 22, as shown in FIG. It is attached to the lower surface of the iron core 12. Thereafter, the rod 4a of the lower vertically moving air cylinder 4 is moved forward, thereby causing the gripping device 7 to rise and separate the iron core 12 upward from the pedestal 21 as shown in FIG.

Thereafter, the rotating shaft 6a of the rotary actuator 6 as a rotational drive means rotates once in the counterclockwise direction, causing the gripping device 7 and thus the iron core 12 to rotate once in the direction indicated by arrow A in FIG. Then, as shown in FIG. 7, the iron core 12 pulls out the tape 18 from the reel 19.
Wrap it around yourself and paste it. At this time, the tape 18 is pulled out so that the adhesive surface 18a is peeled off from the part wound around the reel 19, which acts as a rotational resistance of the reel 19 and puts tension on the tape 18. , the tape 18 is wound around the iron core 12 without slack. By one rotation of the core 12, the winding end portion of the tape 18 is pasted over the tip of the tape 18 that was pasted to the lower surface of the core 12 when the core 12 was pressed against the pedestal 21. It will be in a state where it is worn.

Now, when the tape 18 is wound and attached to the iron core 12 as described above, the rod 14a of the left-right moving air cylinder 14 as the second moving means moves forward, and the supporting plate 1
6 to the left, and the mounting piece 20 is moved to a position slightly leftward from the iron core 12, as shown in FIG. As a result, the pedestal 21 and the cutter 23 move to the left, and the cutter 23 is positioned opposite to a portion near the end of winding the tape 18 around the iron core 12 . Thereafter, the rod 5a of the upper vertical movement air cylinder 5 as the third moving means moves backward, thereby lowering the elevating member 2 and thus the gripping device 7. Then, as shown in FIG. 9, first, a portion of the tape 18 near the end of winding around the iron core 12 is pressed against the cutter 23 and cut, and the tip portion (cut end portion) of the tape 18 on the reel 19 side is cut. is received on the pedestal 21.

After this, the rod 5a of the upper vertically moving air cylinder 5 continues to move backward, so that the iron core 12 further descends and comes into sliding contact with the inclined surface portion 26a of the pressure contact plate 26. As a result, as shown in FIG. 10, the inclined surface portion 26a of the press-contact plate 26 is elastically deformed, and due to its elastic force, a portion near the end of winding of the tape 18 protruding from the iron core 12 is
Press it against the side of 2 to stick it. Then, when the iron core 12 passes through the pressure contact plate 26 and is stopped below it, the gripping bag r
The rod 9a of the pressing air cylinder 9 of I17 moves backward, and the pressing plate 1o releases the clamping of the iron core 12.

Then, the iron core 12 falls onto a conveyor (not shown) disposed directly below it and is conveyed. After this, the rod 5a of the upper vertical movement air cylinder 5 moves forward, and the gripping device 7 rises and returns to its original position, and the rod 14a of the left and right movement air cylinder 14 moves backward. At , the support plate 16 is moved to the right and returned to its original position. With this, one winding cycle of the tape 18 is completed.

As described above, according to this embodiment, the tape 18 can be automatically wound around the iron core 12, and labor can be saved. Furthermore, when the tape 18 is wound, tension is applied to the tape 18 due to the resistance of pulling it out from the reel 19, so there is no fear that the tape 18 will loosen and can be wound without wrinkles.

Note that the object to be wound is not limited to an iron core attached with insulating paper.

C Effects of the Invention] As is clear from the above description, according to the present invention, the tape can be automatically wound around the part of the workpiece to be wound, and moreover, the tape can be wound and pasted while applying tension to the workpiece. This has the excellent effect that there is no risk of wrinkles forming on the tape.
