Description

[Detailed description of the invention] <Industrial field of application> The present invention is for forming a single tape-wrapped bundled wire by winding tape spirally around the outer peripheral surface of multiple wires and converging the wires. The present invention relates to a tape mounting device in a tape winding device.

<Prior art> Conventionally, this type of tape-wrapped condensed wire has been produced by winding hundreds of meters of long wire continuously using a large machine, or by installing it into various electrical devices. Currently, short electric wires that have been cut to length are wrapped with tape by hand.

<Problems to be solved by the invention> Therefore, when the converging wire is wrapped with tape around a long electric wire using a conventional large-scale machine of this kind, when the wire is to be used at a predetermined length, the converging wire may be cut. A predetermined amount of tape must be removed from both sides of the tape, and while it is relatively easy to remove the tape from the rear end in the tape winding direction, it is difficult to remove the tape from the leading end. There was a problem in that the removal action was extremely troublesome, and the position of the tape at the end of the removed remaining portion was disturbed, making it difficult to clean it up in a beautiful state.
In addition, there was a problem in that it was necessary to always have a wide variety of wires on hand, such as combinations of colored wires corresponding to the color coding of various wires for electrical equipment, combinations of large and small wires, and numbers of wires to be bundled. On the other hand,
Since short, hand-wound bundled electric wires are hand-wound, the amount of tape overlap is not constant, making it difficult to obtain a beautiful spiral tape-wound wire. Another problem was that it required a great deal of time and effort.

In addition, there was a problem in that there was no tool for easily and reliably attaching the winding tape, and that attaching the winding tape required a lot of effort, such as removing bolts.

Therefore, the purpose of this invention is to solve one of these problems, which is that it takes time and effort to attach the tape, and to make it possible to attach the rolled tape easily and reliably, thereby improving work efficiency. An object of the present invention is to provide a tape mounting device for a wire convergence tape winding device that can be used in a wire concentrating tape winding device.

<Means for Solving the Problems> The configuration of the present invention for achieving the object will be explained using FIGS. 1 to 5 corresponding to the embodiments.

It is fixed with bolts 9, 9 via d and 4d.
Further, near the outer periphery of the face plate 4a of the wire guide plate 4, a wrapping tape Ta mounting device 3 having a structure to be described later is formed protruding toward the same side as the dogleg shaped curved plate 4b. As shown in FIGS. 2 and 4, the curved plate 4b is formed with a tape T insertion guide groove 4c whose outer end is inclined and whose rear side is along the protruding direction of the curved plate 4b. Reference numeral 20 in FIG. 2 is a lid body attached to the machine frame 10 so as to be openable and closable.

Next, the tape mounting device will be explained.

As shown in FIGS. 4 and 5, the structure of the tape mounting device includes a mounting hole 3 which is screwed into a hole 4e of a wire guide plate 4 mounted on the drum 1 with a screw 9a.

The movable cylinder 33 has an inner cylinder part 33a that fits externally into the cylinder body 31, and a circumferential groove 33c that fits a part of the sphere 32 on the inner circumferential surface of the inner cylinder part 33a, and the fixed cylinder 31.

It is provided with a small ring body 36 that prevents the operating body 34 from jumping out.

In FIG. 5, reference numeral 31b indicates a flange portion protruding from the outer periphery of the base of the fixed cylinder 31, and 36a indicates a flange portion protruding from the outer end of the small ring body 36.

In order to use the wire convergence tape winding device configured in this way, as explained in the section of the above-mentioned operation,
First, the tip of the operating body 34 is pressed, the movable cylinder 33 is taken out so that the sphere 32 can be moved onto the small diameter part 34c of the operating body 34, and the tape Ta is fitted onto the movable cylinder 33. Then, by fitting the movable cylinder 33 into the fixed cylinder 31 while pressing the operating body 34 again, the tape Ta is attached to the machine body.
After the winding tape Ta is attached to the fuselage in this way, the multiple electric wires K to be focused are shown by the chain lines in Fig. 2 and the solid lines in Fig. 3. A winding tape inserted into the electric wire insertion through hole 2 from one end and attached to the tape attachment device 3 at the starting end position for wrapping the tape around the electric wire K.
Wrap the tip of the tape T pulled out from Ta and passed through the guide groove 4c, turn on the power switch 11, and move the electric wire K sequentially in the axial direction while applying it to the doglegged curved plate 4b. . During this operation, if the power switch 11 is set to a hood switch (not shown) that can be operated by stepping on the foot, the power can be easily turned on and off.

When the power switch 11 is turned on in this way,
Motor M rotates, V pulley 7, V belt 8
The drum 1 is rotated via the dogleg-shaped curved plate 4b.
together with the winding tape Ta revolves over the electric wire K...
Tape T is wrapped around electric wire K. This winding action of the tape T causes the electric wire K to move in the axial direction so that the electric wire K is wound spirally as shown in FIG. 3, and a converging electric wire K' in which the tape T is spirally wound is obtained.

When the tape has been wound for the required interval length, the power switch 11 is turned off, the end of the tape is cut, and the focused power source K' is pulled out from the through hole 2.

In this way, the wire convergence tape winding device according to the present invention is used for connecting to electrical equipment.
Since this is a device that collects the necessary number of electric wires K formed into a predetermined short length of cm, and wraps them with tape to converge them into a single wire, both ends of the electric wire K are held by a holder, and this The body may be moved, or the holding body may be fixed, and the machine base 5 of the above embodiment may be moved.

By adopting such a structure, the winding tape Ta is fitted onto the outer peripheral surface of the cylindrical peripheral wall portion 31e of the fixed cylindrical body 31.

The tape mounting device 3 according to the present invention is shown as having a fixed mounting structure using bolts 9a for convenience of explanation in both of the above embodiments, but it may also have a mounting structure in which the angle can be changed freely via a pivot shaft or a ball joint. good.

Further, in the embodiment, the tape mounting device 3 is shown as being attached to the wire guide plate 4, but it goes without saying that it may be attached directly to the drum 1.

Although the embodiments considered to be representative of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments. It can be implemented with appropriate modifications within the scope of achieving the following effects.

<Effects of the invention> As is already clear from the above explanation, the invention has the following effects:
Multiple short electric wires cut to predetermined dimensions used for electrical connection within the device to electrical equipment are wrapped with tape for a predetermined length and bundled together like a single converging wire. This is a tape mounting device for a wire concentrating tape winding device, which has a structure in which a large diameter part, a small diameter part, and an inclined part are formed in the operating body that moves by pressing, and a spherical shape is formed by the movement of the operating body. The movement of the movable cylinder relative to the fixed cylinder is permitted or denied by the movement of the sphere into and out, and the movement of the sphere towards the centripetal side is prevented. The installation and replacement of winding tape on electric wires can be done easily and extremely efficiently, and operations such as changing the winding tape to a different color can be performed easily and quickly, making the work of winding tape around electric wires easier as a whole. We have come to expect this remarkable practical effect.
