Abstract

PURPOSE:To improve the working efficiency and workability of tape winding, by providing a driving source for feed which properly moves a tape support shaft along a longitudinal direction. CONSTITUTION:A tape support shaft is extended to length being long enough to allow holding of plural same or difference winding tapes 3 in parallel, and a driving source 17 for feed, moving a tape support shaft 16 along its longitudinal direction, is coupled to the one end part of the tape support shaft 16. Thereby, the plural winding tapes 3 can be held in parallel to each other on the single tape support shaft 16, and the arbitrary winding tape 3 can be set on a tape winding axis 21 based on a coil 5. Thus, even if the tape member of the one winding tape 3 is all wound, winding of a subsequent tape can be continued only by setting the preliminary winding tape 3, held in parallel on the tape support shaft 16, on the axis 21.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a tape holding device used when winding a tape member such as an insulating tape around a coil in a coil winding machine, etc. This invention relates to a tape holding device for tape winding that can hold winding tapes in parallel and set any winding tape on the tape winding axis.

2. Description of the Related Art As shown in FIG. 3, a conventional tape holding device 1 for tape winding rotates a take-up tape 3 around a single tape support shaft 2 by one turn. held possible. Incidentally, in FIG. 3, reference numeral 4 designates a stopper that holds the winding tape 3 from the tape support shaft 2 so that it does not fall off. For example, in order to wrap an insulating tape around the outer peripheral surface of the coil S after winding is completed, the tip of the winding tape 3 held on the tape support shaft 2 is pulled out, and the guide roller 6.

0 on the rotating shaft 12 of the drive motor 11, and in this state, raise the holding pad 7 in the direction of arrow A, press the adhesive surface of the tape tip 9' against the outer peripheral surface of the coil 5, and vacuum suction with the air vibrator 8. After stopping the drive motor 11,
By driving the rotating shaft 12 in the direction of arrow B, the insulating tape 9 is wound one to three times around the outer peripheral surface of the coil 5.

Problems to be Solved by the Invention However, in such a conventional tape holding device 1, only one roll of one type of winding tape 3 can be held on the tape support shaft 2.

Therefore, when the insulating tape 9 of one winding tape 3 is used up after winding tape around the coil 5 for multiple coils, the stopper 4 at the end of the tape support shaft 2 is removed and the empty core material is removed. After removing it, a new take-up tape 3 had to be set one by one. In addition, it takes a considerable amount of time to replace the winding tape 3.

Further, since the length of the insulating tape 9 etc. wound around the winding tape 3 is usually about 20 to 30 m, the winding tape 3 has to be replaced quite frequently. Furthermore, when winding a different type of tape member around one coil 5 set on the rotating shaft 12, the winding tape 3 held on the tape support IFIl 12 is replaced with a different type of winding tape 3. Alternatively, the bobbin of the coil 5 had to be moved to another tape holding device in which the desired type of winding tape 3 was set. As described above, in the conventional tape holding device 1, the workability of winding the tape around the coil 5 was poor. Therefore, an object of the present invention is to solve such problems.

Means for Solving the Problems The means of the present invention for solving the above-mentioned problems is a tape formed by rotatably holding a take-up tape on which a tape member to be wound around a coil is wound around a single tape spindle. In the winding tape holding device, the tape support shaft is extended to a length capable of holding a plurality of winding tapes of the same type or different types in parallel, and the tape support shaft is attached to one end of the tape support shaft. A drive source for moving the tape as appropriate along the longitudinal direction is connected to the drive source, and the tape spindle is moved by this drive source to select any winding of the plurality of tapes held on the tape spindle. This is achieved by setting the pick-up tape on the axis of the tape winding around the coil.

Embodiments One embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a tape holding device 1 for tape winding according to the present invention.
5 is an explanatory diagram showing Example 5. FIG. This tape holding device 1
Reference numeral 115 is for holding a plurality of winding tapes in parallel and setting any winding tape on the tape winding axis, and is composed of one tape support shaft 16 and a feeding drive source 17. The tape support shaft 16 rotatably holds a winding tape 3 around which a tape member such as an insulating tape or a thin tape-like copper plate is wound around the coil 5, and a plurality of winding tapes 3 of the same or different types. ,3. ... have been extended to a length that can hold them in parallel. and.

A plurality of winding tapes 3, 3 degrees...
1. For example, as shown in FIG. 2, spacers 18 and 18 are interposed between each winding tape 3a, 3b, and 3c, and the outer sides of winding tapes 3a and 3c at both ends are respectively placed with stoppers. 19a.

By stopping at 19b, a plurality of wound tapes are held in parallel.

A drive source 17 for feeding is provided at one end of the tape support shaft 16.
are connected. The feeding drive source 17 moves the tape support shaft 16 along its longitudinal direction in the directions of arrows C and D, and is composed of, for example, a pulse motor or a linear motor. This drive source 17 is
It is designed to be driven by a control signal S from a conventionally known control circuit 20.

Next, the operation of the tape holding device 15 shaped like this will be explained. First, as shown in FIG.
Place b and 3c in parallel and send them to cellar 1, and now,
For example, assume that an insulating tape is wrapped around the outer peripheral surface of the coil 5 that has been completely wound. At this time, as shown in FIG. 1, the bobbin 10 of the coil 5 is
Set to 112. Next, the tape holding device i! Z15
The drive source 17 for feeding is driven to move the tape support shaft 16 in the direction of arrow C or the direction of arrow D. Then, the entire plurality of winding tapes 3 held in parallel on the tape support M16 move in the direction of arrow E or F, and from now on the coil 5
The winding tape 3 on which the desired insulating tape is wound is aligned with the axis 21 of tape winding around the coil 5.
Stop when it matches. Thereby, the desired winding tape 3 is set on the tape winding axis 21 with respect to the coil 5. Next, the tip of the winding tape 3 set in this way is pulled out, and the tip of the insulating tape 9 is vacuum-adsorbed by the air vibrator 8 onto the upper surface of the holding pad 7 via the guide rollers 6.6°... Hold 9'. In this state, the holding pad 7 is raised in the direction of the arrow to press the adhesive surface of the tape tip 9' against the outer peripheral surface of the coil 5, and after stopping the vacuum suction by the air pipe 8, the drive motor 11 is driven. The rotating shaft 12 is rotated in the direction of arrow B.

As a result, the insulating tape 9 pulled out from the winding tape 3 is wound around the outer peripheral surface of the coil 5 one to three times.

Next, the coils 5 set on the rotating shaft 12 are replaced one after another with different ones, and insulating tape is wound in the same manner as described above. When the insulating tape 9 of the winding tape 3 is used up, the feeding drive The source 17 is driven to set the spare winding tapes 3 held in parallel on the tape winding axis 21 of the coil 5.

Thereafter, the insulating tape 9 is wound around the coil 5 in the same manner as described above. In addition, in one coil 5, for example, in order to wind a certain type of insulating tape after winding the negative winding, and then winding another type of insulating tape after winding the secondary winding, it is necessary to start the coil from a certain winding tape 3. An insulating tape is wound on the primary winding of 5, and after the secondary winding is wound, the feeding drive source 17 is driven to wind another type of winding tape 3 held in parallel. It is only necessary to set it on the axis 21 of .

In addition, in FIG. 1 and FIG. 2, three winding tapes 3 are shown as being held in parallel on the tape support shaft 16, but the present invention is not limited to this. Alternatively, there may be four or more.

Further, the tape holding device 15 of the present invention may be applied to the tape winding portion of a coil winding machine, or may be applied to an independent tape winding machine.

Effects of the Invention As described above, the present invention extends the tape support shaft 16 to a length that can hold a plurality of wound tapes 3 of the same type or different types in parallel, and also extends the tape support shaft 16 to a length that can hold a plurality of wound tapes 3 of the same type or different types in parallel. Since the tape support shaft 16 is connected to a feeding drive source 17 that moves the tape support shaft 16 appropriately along its longitudinal direction, a plurality of wound tapes 3 can be held in parallel on one tape support shaft 16, and Any winding tape 3 can be set on the axis 21 of tape winding around the coil 5. Therefore.

Even if the tape member of one winding tape 3 runs out.

Tape spindle 1 can be replaced without replacing each time as in the past.
The subsequent tape winding can be continued simply by setting the spare winding tape 3 held in parallel with the tape winding tape 3 on the tape winding axis 21. Also, when winding different types of tape members around one coil 5, the tape support shaft 16 can be used without replacing the winding tape 3 or moving the coil 5 to another location as in the past. It is only necessary to set another type of winding tape 3 held in parallel to the tape winding axis 21. For these reasons, according to the present invention, the efficiency and workability of winding tape around the coil 5 can be significantly improved.
