Description

[Detailed Description of the Invention] The present invention relates to a device for winding a wire wound on a reel onto another reel, and is particularly suitable for use when winding welding wire from a large reel to a small reel.

In recent years, welding automation has progressed, and welding is not limited to automatic downward welding such as conventional submerged arc welding.
TIG and MIG all-position automatic welding has been developed and put into practical use. However, in the case of automatic welding in all positions, the entire welding head is rotated in the circumferential direction of the workpiece, so the device needs to be lightweight. Therefore, the welding wire is wound from a large reel (10 to 20 kg) to a small reel (1 to 2 kg).

FIG. 1 shows a perspective view of a conventional wire winding device winding welding wire.

A support plate 2 for a reel to be wound is vertically provided on the upper surface of one end of the base 1, and a support shaft 2a is fixed at right angles to the side surface of the support plate 2 for the reel to be wound. A motor guide 4 to which a feed motor 3 is attached is provided on the upper surface near the other end of the base 1 so that its side surface is in the same straight line as the side surface of the take-up reel support plate 2.
A rotary shaft 5 that rotates in response to the output of the feed motor 3 is rotatably supported so that its center of rotation is perpendicular to the side surface of the motor guide 4. Therefore, the support shaft 2a attached to the take-up reel support plate 2 and the motor guide 4
It is parallel to the rotating shaft 5 supported by. A roller frame 6 is fixed on the upper surface of the base 1 near the take-up reel support plate 2 between the take-up reel support plate 2 and the motor guide 4, and the roller frame 6 has a rotating shaft 5 and a shaft. Guide rollers 7 and 7a are rotatably arranged in parallel to each other to regulate the position of the wire. A winding adjustment frame 8 is located between the roller frame 6 on the upper surface of the base 1 and the motor guide 4. A guide shaft 8a is fixed to the adjustment frame 8 parallel to the rotating shaft 5 of the motor guide 4.A pulley 9 is attached to the guide shaft 8a and is rotatable with respect to the guide shaft 8a and slides in the axial direction. It is set up so that it can move freely. Further, on the base 1, there is provided an operation box 10 in which an operation switch for the feed motor 3 and the like are attached.

When winding welding wire from a large reel to a small reel using the wire winding device with the above configuration,
Do it as follows.

A small reel 12 for winding welding wire 11 is attached to a rotating shaft 5, and a large reel 13 around which welding wire 11 is wound is attached to a rod 2a of a reel support plate 2 to be wound. Next, the welding wire 11 is attached to the small reel 12 between the rollers 7 and 7a via the pulley 9, and the motor drive switch of the operation box 10 is turned on. When the feed motor 3 is driven, the small reel 12 rotates, and the welding wire 11 wound around the large reel 13 is transferred to the small reel 12 via the guide rollers 7 and 7a of the roller frame 6 and the pulley 9 of the adjustment frame 8. It gets rolled up. At this time, the operator reciprocates the pulley 9 along the guide shaft 8a in accordance with the rotational speed of the feed motor 3 so that the welding wire 11 is wound around the large reel 13 in an orderly manner. The welding wire 11 is wound onto a small reel 12.

However, when winding the welding wire using the conventional winding device described above, the welding wire 1
The operator manually moves the pulley 9 to adjust the orderly winding of the roll 1.
During winding, you cannot take your hand off the pulley 9, and the peripheral speed of the small reel 12 changes as the welding wire 11 is being wound, so the rotational speed of the small reel 12 and the moving speed of the pulley 9 are It is difficult to find a balance. Furthermore, welding wire 11
Since the guide rollers 7 and 7a for guiding the welding wire 11 are provided parallel to the rotation axis of the reel, the welding wire 11 cannot be regulated in the lateral direction.
This makes it difficult to adjust the pulley 9, and as a result, it becomes difficult to wind the welding wire 11 in an orderly manner.

The present invention was developed in view of the above-mentioned situation, and includes a wire rod between the take-up reel support shaft and the take-up reel drive shaft, which regulates the position of the wire in the shaft width direction of the take-up reel drive shaft. To provide a wire winding device equipped with a guide mechanism and a winding position adjustment mechanism that adjusts the position of the wire to be wound by swinging, thereby automatically and orderly winding the wire from reel to reel. The purpose is to

The structure of the present invention to achieve this purpose is as follows:
A reel support shaft and a rotatable reel drive shaft are provided with a space between them, and a wire wound on a reel attached to the reel support shaft is inserted between the reel support shaft and the reel drive shaft in the axial direction of the reel drive shaft. A wire guide mechanism for regulating the position is provided, and a winding position adjustment mechanism having a wire guide part that is swingable and movable in the axial direction of the reel drive shaft is provided between the wire guide mechanism and the reel drive shaft. It is characterized by becoming.

A roller frame 21 is fixed near the take-up reel support plate 2 between the take-up reel support plate 2 and the motor guide 4 on the upper surface of the base 1, and the roller frame 21 has guide rollers for guiding the wire. 22,2
2a are arranged in parallel so as to be rotatable around a vertical axis.
Further, a winding adjustment device 23 is provided between the roller frame 21 on the upper surface of the base 1 and the motor guide 4 to adjust the winding position of the wire rod. As shown in FIG. 3, the winding adjustment device 23 is movable on a support 25 attached to the base 1 via an adjustment screw 25a parallel to the longitudinal direction of the rotating shaft 5 attached to the motor guide 4. A holding stand 26 is provided, and a swing pin 27 attached to the holding stand 26 in a direction perpendicular to the rotating shaft 5 is provided.
A pulley frame 29 is pivotally supported via a bearing 28 fitted into the swing pin 27 so as to be swingable. A pulley 30 is rotatably provided above the pulley frame 29 with its center of rotation parallel to the center of rotation of the rotating shaft 5.

In other words, in the winding adjustment device 23, the holding stand 26 moves in the longitudinal direction of the rotating shaft 5 with respect to the base stand 1, and the pulley frame 29 to which the pulley 30 is attached swings in the width direction of the rotating shaft 5 with respect to the holding stand 26. This is how it has become.

A limit switch 31 for confirming completion of wire winding is attached directly below the rotating shaft 5 on the upper surface of the base 1.

The operation of winding the welding wire wound on a large reel onto a small reel using the apparatus having the above configuration is performed as follows.

A small reel 12 for winding welding wire 11 is mounted on a rotating shaft 5, and a large reel 13 around which welding wire 11 is wound is mounted on a support shaft 2a of a reel support plate 2 to be wound. Next, fix the roller frame 21 by aligning the center of the roller frame 21 with the longitudinal center of the large reel 13, and fix the roller frame 21 with the adjusting screw 25a.

At this time, the position of the welding wire 11 is regulated in the width direction by the roller frame 21, and the pulley frame 29 swings according to the winding position of the small reel 12 due to the tension of the welding wire 11, so that the welding wire 11 The small reel 12 is wound in an orderly spiral shape without any gaps or overlaps. When the welding wire 11 is wound to a specified length on the small reel 12, this is detected by the limit switch 31, the feed motor 3 is stopped, and the winding is completed.

Although the above-mentioned embodiment is used for winding welding wire, it is of course possible to apply it to winding other wire materials such as electric wire. In addition, although the pulley is swung as a means for adjusting the winding position, it can support the wire rod that swings the pulley, and it can be moved in the axial direction of the rotating shaft depending on the relationship between the tension of the wire and the winding position. It's fine as long as it's something. Furthermore, although the limit switch is used to detect the completion of winding, other means such as a proximity switch may be used, and the mounting position is not limited to the above embodiment.
