Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a taping machine for winding an insulating tape around an armature coil conductor of a rotating electric machine.

[Technical background of the invention and its problems]

Conventionally, in this type of taping machine, when winding insulating tape around the armature coil conductor, the insulating tape may break, but this tape breakage was detected visually by the operator. .

For this reason, when a tape break occurs, the insulating tape wound around the armature coil conductor is unwound one after another, so when replenishing the next insulating tape and taping, use the unwound tape in advance. I had to rewind it and restart it.
In addition, even if the tape breaks, there is no tape holder, so it is not possible to use unmanned machines or have one worker take charge of multiple taping machines, so it is not possible to use multiple machines, which increases the efficiency of tape winding. The drawback was that it was bad.

[Purpose of the invention]

The present invention has been made to eliminate the above-mentioned drawbacks, and provides a taping machine that can automatically detect tape breakage and press the tape, thereby improving tape winding efficiency. The purpose is to

[Summary of the invention]

In order to achieve such an object, the present invention has a tape breakage detection device that operates and stops the operation when a tape breakage occurs during taping operation or when the tape runs out, and a tape breakage detection device that prevents tape breakage from occurring. Some devices are equipped with a tape pressing device that operates when detected and presses down the tape wound around the band member so that it does not unwind.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are a front view and a side view of a taping machine equipped with a tape break detection device A and a tape pressing device B. FIG. 1 and 2, 1 is a frame, a ring receiver 2 is attached to this frame 1, and a rotating ring 3 having teeth formed on the outer peripheral surface is fitted into the ring receiver 2 so as to be rotatable and slidable. It is. This rotary ring 3 is provided with a notch 3a in the center of its hollow portion for setting or taking out the coil conductor 4. In addition, a pair of gears 5a and 5b built into the taping machine body are meshed with the rotating ring 3 at appropriate distances with teeth formed on the outer circumferential surface of the rotating ring 3. gears 5a, 5b
The rotation of the electric machine 7 is transmitted through a gear 6 that meshes with the rotating ring 3, thereby rotating the rotating ring 3. A tape reel 8 is rotatably attached to the rotating ring 3, and an insulating tape 9 is set on the tape reel 8.
Further, reference numerals 10 and 11 designate guide rollers that are rotatably attached to the rotary ring 3 at an appropriate distance from each other around pins 12 and 13, respectively. Therefore, the insulating tape 9 set on the tape reel 8 is guided to the coil conductor 4 via the guide rollers 10 and 11.

Further, reference numeral 14 denotes a rotating ring 3 located outside the guide roller 10, the details of which are shown in FIG.
A lever is rotatably attached to the lever via a fulcrum pin 15, and this lever 14 is stretched between a stopper 16 attached to one side of the lever and a stopper 17 attached to the rotating ring 3. spring 1
8, a tensile force is constantly applied to rotate it in the direction of the arrow R shown in the figure. Further, a roller 20 is rotatably attached to the rotating end of the lever 14 via a pin 19 as shown in FIG.
0 and 11, and is pushed up by the tension of the insulating tape 9 against the tension of the spring 18. Further, a detection lever 21 is attached to the fulcrum pin 15 side of the lever 14.
Reference numeral 22 denotes a tape break detector attached to the top surface of the frame 1. When the tape breaks, the lever 14 is rotated by the tensile force of the spring 18, and the detection lever 21 is rotated to the position where it hits the stopper 22a. It activates when you move it.

On the other hand, 23 is a rotary actuator attached to the lower part of the frame 1, as shown in FIGS. 5 and 6 in detail. When detected, it is rotated by the detection signal. 24 is a pair of flexible tape press bars attached to both ends of the rotating shaft 23a of the rotary actuator 23;
This tape presser bar 24 has a length such that its rotating end can come into contact with the surface of the coil conductor 4 when it rotates around the rotating shaft 23a.

The tape break detector 22 may be a limit switch, a touch switch, a non-contact switch, or the like.

Next, the operation of the taping machine configured as described above will be described. Now, the rotating ring 3 is connected to the gear 6 and a pair of gears 5a and 5b by the electric machine 7.
Assuming that the coil conductor 4 is moving straight at a constant speed, the insulating tape 9 is moved from the tape reel 8 to the guide rollers 10 and 1.
1 to the coil conductor 4 while being taped. In this case, the tape detection roller 20 provided at the rotating end of the lever 14 is lifted by the tension of the insulating tape 9 between the guide rollers 10 and 11. In such a state, when the insulating tape 9 breaks, the tape detection roller 20 becomes free because the tape tension disappears. Then, the lever 14 is moved by the spring 18
The detection lever 21 rotates about the fulcrum pin 15 in the direction of the arrow R shown in the figure due to the tensile force of the detection lever 21, and stops at the position where the detection lever 21 hits the stopper 22a. When the detection lever 21 is rotated to the stopper 22a position, a tape break detector 22, such as a limit switch, is activated, and the operation of the taping machine is stopped based on the detection signal. At the same time, when a detection signal from the tape break detector 22 is input to the rotary actuator 23, the rotary actuator 23 rotates, and a pair of tape holding bars 24 attached to both ends of the rotating shaft 23a move as shown by the arrows in the figure. By rotating in the S direction, the insulating tape 9 wound around the coil conductor 4 is clamped and held down from both sides of the coil conductor 4.

In this case, since the tape holding bar 24 is flexible, even if the dimensions of the coil conductor 4 change,
Furthermore, even if the shape changes at the corner portion of the coil conductor 4, this can be accommodated, so there is no possibility of damaging the insulating tape 9 or the like.

The above description has been made regarding the operation when the tape runs out, but it goes without saying that the same operation as described above also occurs when the insulating tape 9 set on the tape reel 8 runs out.

In this embodiment, when a tape break occurs, the lever 14 is rotated about the fulcrum pin 15 by the tension of the spring 18, and the detection lever 21 attached to this lever 14 operates the tape break detector 22. At the same time, when the operation of the taping machine is stopped, the rotary actuator 23 is actuated by the detection signal of the tape break detector 22, and the tape is wound around the coil conductor 4 by the tape holding bar 24 attached to the rotary shaft 23a. Since it is configured to press down the insulating tape 9,
Even if a tape break occurs, it can be automatically detected without operator supervision, and the insulating tape 9 wound around the coil conductor 4 will not be unwound. This makes it possible to operate the taping machine unmanned or to have one worker take charge of a plurality of taping machines, thereby improving tape winding work efficiency.

In addition, although the above embodiment has been described with reference to the case where the insulating tape is wound around the armature coil conductor of a rotating electric machine, the present invention is not limited to this, and it is not necessary to wind the tape around the belt-shaped member. It can be applied to all things that exist.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to automatically detect tape breakage and press the tape, thereby providing a taping machine that can improve the efficiency of tape winding around a band-shaped member.
