DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape winding device and a tape winding method for taping a work such as an electric wire bundle.

[0002]

2. Description of the Related Art Conventionally, in the process of manufacturing a wire harness, taping has been performed on a work such as an electric wire bundle and its exterior parts (mainly a corrugated tube). This taping operation is usually performed by a tape winding device provided with a taping head for rotating a tape reel around an electric wire by a driving source such as a motor.

[0003] Among the currently known tape winding devices,
When taping a relatively long work (for example, about 2 m), a) a hand-held operation type in which an operator moves the taping head itself along the work to perform a tape winding operation (for example, Japanese Unexamined Patent Publication No. Hei 07-61415,
(See Japanese Patent Application Laid-Open No. 7-215598 and Japanese Patent Application Laid-Open No. 07-101641) or b) By automatically displacing the taping head and the electric wire bundle in the longitudinal direction of the electric wire bundle with an automatic traveling device, the tape is automatically attached to the electric wire bundle. (See, for example,
6-183413, JP-A-07-304571, and JP-A-10-152265).

[0004]

In the case of the type a), the operator has to carry a heavy taping head, which imposes a heavy burden on the operator.

On the other hand, the type b) has a problem that the tape cannot be wound neatly on both ends of the work.

In particular, when taping is required for a long wire bundle having connectors connected to both ends, a feed speed of a taping head (or a bundle of wires) and a tape wrapping condition at the time of taping for a portion near both connectors. , The winding margin, the tension of the tape at the time of winding, and the like must be finely changed. Therefore, such a fine adjustment cannot be sufficiently performed by the conventional apparatus.

For this reason, there has been a problem that the wire bundle is twisted on the downstream side of the taping area, and that the tape cannot be wound to the end portion of the wire bundle.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a tape winding device and a tape capable of applying fine taping to an end portion of a wire bundle having connectors connected to both ends. It is an object to provide a winding method.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a tape reel carrying a tape roll so as to be capable of displacing a tape feeding posture, and a tape reel comprising:
A taping head having a rotatable drive around a pivot center where the workpiece is arranged, a linear workpiece stretched along the pivot center of the taping head, and the taping head are arranged along the longitudinal direction of the workpiece. A drive mechanism that relatively displaces the tape, and a tape winding device that winds the tape fed from the tape reel from one end side to the other end side of the work, wherein the relative displacement by the drive mechanism when the taping head taps the work is provided. The speed is reduced when the taping head and the other end of the work come close to each other, and after deceleration, the relative displacement between the two is advanced to a position where the taping head passes through the other end of the work. Reverse tapping of the other end by reversing the relative displacement of
A tape winding device comprising an interlocking control unit for interlockingly controlling the driving mechanism with the taping head.

According to the present invention, when taping from one end to the other end of a linearly stretched work, the tape reel is rotated by a taping head and a driving mechanism is used in the same manner as in a known device. Taping is performed by the relative displacement operation between the taping head and the workpiece due to the above. When the tape fed from the tape reel approaches the other end of the work, the interlocking control unit reduces the displacement speed by the drive mechanism and causes the relative displacement between the taping head and the work to proceed. Due to this deceleration forward operation, the tape fed from the tape reel becomes slack, and excessive tension does not act on the work. Thereafter, when the relative displacement between the taping head and the work reverses, the tape fed out in a slack state is smoothly wound around the work.

The relative displacement between the taping head and the work is preferably made by reciprocating the taping head itself and fixing the work at a fixed position, but may be reversed.

In a preferred aspect, the taping head includes a head main body, a rotating body rotatably provided around the turning center with respect to the head main body and carrying the tape reel, and a turning center with respect to the rotating body. A work guide that guides the work to the center of rotation, and the work guide is
From the time when the relative displacement speed is reduced to the time when the taping operation of the other end is completed, the other end of the work is held at a position where it can be guided. In this way, the tape can be neatly wound around the end portion of the work by the work guide even in the process of moving the rotating body forward / backward.

In a preferred aspect, the work guide has a guide slit for guiding a tape wound around the work. In this aspect, even if the work has a relatively small diameter, the tape is precisely guided by the work via the guide slit, so that a good taping state can be obtained.

[0014] In a further preferred aspect, there is provided an elastic body provided between the work guide and the rotating body, and the relative displacement between the taping head and the work is preceded by the elastic force of the elastic body. Is configured to reverse. This makes it possible to switch the relative displacement direction between the taping head and the work by using only a simple mechanical structure without requiring a complicated control mechanism.

[0015] In a further preferred aspect, the tape reel has a toggle mechanism for switching the attitude of the tape roll in conjunction with the reverse movement of the taping head and the work. In this way, it is possible to automatically displace the tape withdrawing direction to the optimum direction according to the taping state, so that it is easy to wind the end portion where automatic taping is difficult, and to obtain a good finished state. It is possible to obtain.

Another aspect of the present invention is a tape reel that carries a tape roll so as to be capable of displacing a tape feeding posture;
A taping head having this tape reel so as to be able to rotate around a turning center where the work is arranged, a linear work stretched along the turning center of the taping head, and the taping head, By a tape winding device having a drive mechanism that relatively displaces along the longitudinal direction, a tape winding method for winding a tape fed from the tape reel from one end to the other end of the work, wherein the taping head holds the work. The relative displacement speed by the drive mechanism at the time of taping is reduced when the taping head and the other end of the work come close to each other, and after deceleration, the relative displacement between the two is moved until the taping head passes through the other end of the work. Forward, then reverse the relative displacement between the taping head and the workpiece And by a tape winding method is characterized by winding the tape fed out in the state that caused the slack in the tape fed out from the tape reel on the outer periphery of the workpiece.

Referring to FIG. 1 and FIG. 1, when the taping head 100 approaches the downstream unit 30, the interlocking control unit 200 reduces the operating speed of the drive motor 12 a of the LM actuator 12, Decrease the moving speed. This deceleration timing is
Since it differs depending on various taping conditions, experimental values are collected in advance and input to the microprocessor of the interlocking control unit 200 in advance. As a result, the taping head 100 approaches the downstream unit 30 while decelerating, and its rotary sleeve 120 is displaced to the outer periphery of the table plate 32c of the downstream unit 30 as shown. Due to this displacement operation, the tape T fed from the tape reel 170 of the taping head 100 is fed with a slight slack. On the other hand, the electric wire guide 154 of the slide unit 150 attached to the taping head 100 has a guide plate 1 provided at the downstream end thereof.
55 is brought into contact with the upstream end of the downstream unit 30 (the end face of the holding claw 33f of the wire clamp 33 shown in FIG. 3), and the displacement thereafter is regulated. On the other hand, since the rotating sleeve 120 goes forward while decelerating thereafter, the rotating sleeve 120
And the slide unit 150 are relatively displaced along the turning center O.

FIG. 16 is a schematic plan view schematically showing the taping operation on the downstream side in the embodiment of FIG.
(A) shows when the slide unit 150 is in contact, and (B) shows when the slide unit 150 and the rotary sleeve 120 are displaced relative to each other.

As shown in FIGS. 16A and 16B, when the slide unit 150 comes into contact with the upstream end of the downstream unit 30 as described above, the rod 158 integrated with the slide unit 150 (therefore, the rod 158). The nut 160) fixed to the rear end also stops at the fixed position,
Thereafter, when the rotating sleeve 120 moves forward, the coil spring 161 is compressed between the guide member 159 attached to the stay 151 of the rotating sleeve 120 and the nut 160 of the rod 158 (FIG. 16 ( B)).

When the compression state reaches a predetermined position, the interlock control unit 200 stops the operation of the drive motor 12a (see FIG. 1). Then, the rotating sleeve 120 is moved backward from the downstream side to the upstream side by the elastic force of the coil spring 161 compressed this time.

FIG. 17 is a schematic plan view schematically showing the taping operation on the downstream side in the embodiment of FIG.
(A) shows a slide unit 150 and a rotating sleeve 120.
(B) shows the time when the rotary sleeve 120 has moved backward from the state shown in (A).

Referring to FIG. 17A, rotating sleeve 1
When the tape reel 20 moves backward, the tape reel 170 reverses integrally with the rotary sleeve 120. The reverse movement triggers the connection shaft 176 connecting the main holder 171 and the sub holder 172 of the tape reel 170.
The sub holder 172 rotates around, and is displaced from the inclined posture to the orthogonal posture (see FIG. 17B). As a result, the slackened tape T is smoothly wound around the outer circumference of the wire bundle W.

When the winding operation is completed, the rotating sleeve 120 stops in the same posture as the initial state. After the rotation sleeve 120 is stopped, the tape cutting unit 180 operates as described with reference to FIGS. 12A and 12B, and the cutter 181 cuts the wound tape T.

As described above, in the above-described embodiment, when taping from one end to the other end of the wire bundle W stretched linearly, the tape by the taping head 100 is used similarly to a known device. Turning operation of the reel 170;
When the taping is performed by the relative displacement operation between the taping head 100 and the wire bundle W by the drive mechanism (the motor 12a of the LM actuator 12), the tape T fed from the tape reel 170 approaches the other end of the wire bundle W. Then, the interlocking control unit 200 sets the motor 12
The relative displacement between the taping head 100 and the wire bundle W is made to proceed forward by reducing the displacement speed due to a. Due to this deceleration forward operation, the tape fed from the tape reel 170 becomes slack, and excessive tension is applied to the wire bundle W.
Will not work. Thereafter, the relative displacement between the taping head 100 and the wire bundle W reverses, so that the tape T fed out in a slack state is smoothly wound around the outer periphery of the wire bundle W. Therefore, in the above-described embodiment, the taping operation by the skilled worker can be automated.

The taping head 1 according to the present embodiment
Reference numeral 00 denotes a carrier 110, a rotating sleeve 120 rotatably provided around the pivot center with respect to the carrier 110 and carrying the tape reel 170, and a relative displacement along the pivot center with respect to the rotating sleeve 120. A work guide (wire guide) 154 that guides the wire bundle W to the center of rotation, and taps the wire guide 154 at the other end of the wire bundle W after the taping head 100 decelerates. Until the work is completed,
Since the other end of the wire bundle W is held at a position where it can be guided, the tape can be neatly wound around the end portion of the work by the work guide even in the process of moving the rotating body forward / backward. . Still more preferably,
Using an electromagnet or the like, the table plate 32c and the wire guide 1
A predetermined position (for example, the guide plate 155) may be sucked.

Further, since the wire guide 154 has the guide slit S for guiding the tape wound around the wire bundle W, even if the wire bundle W has a relatively small diameter, the guide slit S Since the tape is precisely guided by the wire bundle W via S, it is possible to obtain a good taping state.

In this embodiment, the electric wire guide 1 is used.
A compression coil spring 161 is provided between the rotary sleeve 120 and the rotary sleeve 120 as an elastic body.
Since the relative displacement between the taping head 100 and the wire bundle W is reversed from the forward direction by the elastic force of 1, the taping head 100 can be formed by a simple mechanical structure without a complicated control mechanism. There is an advantage that it is possible to switch the relative displacement direction between the wire bundle and the wire bundle W.

In addition, the tape reel 1 according to the present embodiment
70 is a toggle mechanism (connecting shaft 176, toggle pins 173a, 173b) for switching the attitude of the tape roll R in conjunction with the reverse movement of the taping head 100 and the wire bundle W.
Etc.), it is possible to automatically displace the tape T withdrawing direction to the optimum direction according to the taping state, and it is also easy to wind the end portion where automatic taping is difficult. There is an advantage that it is possible to obtain a perfect finished state.

The relative displacement between the taping head 100 and the electric wire bundle W is preferably such that the taping head 100 itself is reciprocated to fix the electric wire bundle W at a fixed position, or vice versa.

The above embodiment is merely an example of a preferred specific example of the present invention, and the present invention is not limited to the above embodiment. It goes without saying that various design changes are possible within the scope of the claims of the present invention.

As described above, according to the present invention,
It also has a remarkable effect that a precise taping can be performed by automatic operation even to the terminal end portion of a wire bundle having connectors connected to both ends.
