DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous winding device for obtaining a bobbin winding material used as a conductor of an electric wire or a cable, and a bobbin switching method.

[0002]

2. Description of the Related Art Conventionally, a wire rod such as a conductor of an electric wire or a cable is continuously wound on a continuous winding machine while a rough wire drawn by a continuous casting rolling method or a dip forming method is drawn to a predetermined diameter by a wire drawing machine or the like. , Where it is manufactured from a bobbin wound wire continuously wound on a rotating bobbin.

FIG. 4 is a front view showing a basic structure of a conventional continuous winding machine 1 for obtaining the bobbin winding wire, and FIG.
Is a plan view thereof.

As shown in the figure, a continuous winding machine 1 has a traverse section 2 for guiding a wire W continuously sent from a wire drawing machine or the like, and a wire rod sent through the traverse section 2. A pair of bobbins 3a and 3b for winding W alternately, a pair of arbor shafts 4a and 4b for detachably holding and rotating these bobbins 3a and 3b, respectively, and a pair of arbor shafts for cutting the wire W at the time of winding switching. Cutter part 5
a, 5b, a pair of setting roll portions 6a, 6b and a drawing roll portion 7 for controlling the passing position of the wire W, a tubular terminal cover 8 alternately covering the bobbins 3a, 3b, respectively, and the terminal cover 8 And line drawing roll section 7
And a pair of unloader parts 10a, 10b, etc., which separate the bobbins 3a, 3b separately from the arbor shafts 4a, 4b, respectively. I have.

As shown in FIGS. 6 and 7, when the first bobbin 3a around which the wire W is wound is fully wound, the traverse portion 2 located above the bobbin 3a is moved to the arbor shaft 4b. Move to the side,
If the bobbin 3b held by the arbor shaft 4b starts rotating in the opposite direction with respect to the bobbin 3a and the winding peripheral speeds of both bobbins 3a and 3b are synchronized thereafter, as shown in FIG. After the setting roll portion 6a projects and the other setting roll portion 6b retreats, the line pulling roll portion 7 is pulled together with the terminal cover 8 along the guide shaft 9 toward the bobbins 3a, 3b. Note that the line drawing roll portion 7 and the terminal cover 8 are integrally formed, and are drawn or pushed back along the guide shaft 9 by a drawing cylinder 11 provided coaxially with the guide shaft 9. I have. Further, since a pair of guide rods 12, 12 are provided on both sides of the guide rail 9 so as to be parallel to the guide rail 9, it is difficult for the line drawing roll portion 7 to rotate about the guide shaft 9 as an axis. There is no terminal cover 8
Is rotatable about the guide shaft 9 toward the arbor shaft 4b.

When the drawing roll 7 is drawn toward the bobbins 3a and 3b in this manner, the wire W extending from the traverse portion 2 to the bobbin 3a is further supported by the bobbin receiver of the arbor shaft 4b with the setting roll 6a as a fulcrum. The periphery of the bobbin 3a which is fully wound is covered by the terminal cover 8 which is pressed against the plate 13b and moves at the same time. Then, the wire W is caught by the chuck portion 5b which rotates together with the bobbin receiving plate 13b, sent in the rotational direction together with the chuck portion 14b, and passes at high speed with the cutter portion 5b fixed around the bobbin receiving plate 13b. After being cut by
It is wound around the bobbin 3b as it is.

On the other hand, the bobbin 3a in which the wire W is cut and thus fully wound is not entangled with the adjacent empty bobbin 3b or the like because the end of the wire W is broken by the terminal cover 8 located around the bobbin 3a. 8 and 9, after the terminal cover 8 returns to the original position and is switched to the other bobbin 3b side, the arbor shaft 4a is moved by the unloader section 10a. And is conveyed out of the winder 1.

Then, a new empty bobbin 3a is attached to the empty arbor shaft 4a side, and the terminal cover 8 is rotated to the arbor shaft portion 4b side, and the winding is performed in the process. When the other bobbin 3b is fully wound, the same operation as described above is repeated alternately, so that a bobbin wound wire having a winding layer of the wire W on the bobbin is continuously obtained at regular intervals. become.

[0009]

As shown in FIGS. 8 and 9, a protective measure 15 is provided around the continuous winder 1 from the viewpoint of ensuring safety and the like. The bobbin switching operation is performed by the operator directly opening and closing the front doors 16a and 16b provided on the front surface of the protective measure 15 as shown in the figure.

Therefore, while the winding machine 1 is in operation, at least one or more workers must be stationed near the work to perform the work, and there is an inconvenience that much labor and labor are required. .

Also, the switching work (rotational movement) of the terminal cover 8 is manually performed by the worker with the full-length doors 16a and 16b opened, but since the bobbin is rotating at high speed in the vicinity thereof, It is highly dangerous and may cause a serious accident.

Further, in the bobbin switching operation by hand, it takes a lot of time to get used to the operation, and an unexpected human error is likely to occur during the operation, and the operation is often interrupted during the operation, resulting in low operation efficiency. There is also a problem.

Accordingly, the present invention has been devised to effectively solve such a problem, and its purpose is to perform such a series of bobbin switching operations without relying on humans.
An object of the present invention is to provide a novel continuous winding device that can be automatically and efficiently performed, and a bobbin switching method thereof.

[0014]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a wire is wound alternately around a pair of bobbins, and the fully wound bobbin-side wire is automatically cut and cut. After winding the wire around the other bobbin,
In a continuous winding device in which the periphery of a full bobbin is covered with a terminal cover movable in the axial direction, and then the full bobbin is taken out at a traverse portion, a front surface provided in the bobbin take-out direction. An automatic opening and closing mechanism for automatically opening and closing the door by linking the door to the traverse portion, and a turning movement mechanism for linking the terminal cover to the traverse portion and turning the terminal cover toward the other bobbin around the bobbin as an axis. It is. Then, after automatically opening the front door provided in the direction of taking out the bobbin and taking it out by an automatic opening / closing mechanism, the terminal cover is swiveled toward the other bobbin around the bobbin by the swiveling movement mechanism. Therefore, a new empty bobbin is attached to the removed bobbin side in the traverse section, and then the front door is closed by the automatic opening / closing mechanism.

This makes it possible to automatically perform the bobbin switching operation, which has conventionally relied on manual operations, that is, the operation of opening and closing the front door and the operation of switching the terminal cover. In addition, the efficiency of the winding operation and the switching operation can be improved.

Is pivoted toward one of the arbor shaft portions 4a and 4b, and at the same time, the rotation angle is detected by the rotation angle sensor 30 so that the terminal cover 8 is connected to the axes of the arbor shaft portions 4a and 4b. Positioning is performed with high precision so as to be coaxial. In addition, this turning motor 2
Reference numeral 8 is automatically controlled by a controller (not shown) linked with a predetermined movement of the unloaders 10a and 10b described later.

On the other hand, these arbor shaft portions 4a, 4
In the area around b and the like, a protective measure 15 made of a wire mesh or the like is provided to restrict the entry of workers, and at the front, that is, at the front of the bobbins 3a and 3b in the carry-in / out direction.

In the drawing, reference numeral 2 denotes a traverse section for guiding the wire W continuously sent from the wire drawing machine or the like to the apparatus as described above, and 6a and 6b control the flow position of the wire W. The setting rollers 14a and 14b are provided with chuck portions provided on the outer peripheral side of the drum receiving plates 13a and 13b of the arbor shaft portions 4a and 4b, and 5a and 5b cut the wire rod W engaged with the chuck portions 14a and 14b. It is a cutter to do.

Next, an embodiment of a bobbin switching method using the continuous winding device having such a configuration will be described mainly with reference to FIG. These series of movements are automatically performed by a controller (not shown).

First, when the left bobbin 3a is near full scale in the state shown in FIG. 1 (S1), the traverse unit 2 located above it is moved to the right bobbin 3b (S2). At the same time, the bobbin 3b is started to rotate (S4), and its peripheral speed is synchronized with the peripheral speed on the bobbin 3a side (S4).

Next, if the peripheral speeds of the bobbin 3a and the bobbin 3b are synchronized, the drawing cylinder 11 draws the line drawing roller 7 and the terminal cover 8 along the spline shaft 21 toward the bobbin (S5). 7, the setting rollers 6a, 6b are operated to cut the wire W, and the cutting upstream end is engaged with the chuck portion 14 to start winding the bobbin 3b (S6). At the same time, the rotation of the wire W is stopped on the bobbin 3a side, but the periphery of the wire W is covered with the terminal cover 8, so that the end of the wire W is scattered and entangled on the other bobbin 3b side, or the spline Shaft 21

Only the swivel is moved toward the bobbin 3b where the winding is performed (S8). Since the turning angle is monitored by the turning angle sensor 31, the terminal cover 8 that has turned and stopped accurately stops at the fixed position so as to be coaxial with the bobbin 3b (S9).

In this manner, the terminal cover 8 is attached to the bobbin 3b.
If it is avoided, the setting rollers 6a and 6b return to the original position (S10), and the front door 16a on the bobbin 3a side is opened by the automatic opening / closing mechanism 32 (S1).
1) After that, the unloader unit 10a located on the front surface of the unloader unit 10a advances toward the bobbin 3a and stops below the bobbin 3a (S1).
2), the bobbin 3a is detached from the urban shaft 4a, transported as it is to the outside of the front door 16a, stopped at the original position (S13), transferred to a transporting means (not shown), and then a new empty bobbin 3a is returned to the original state. After attaching to the urban shaft 4a side (S14) and returning to the original position again, the front door 16a is closed by the automatic opening / closing mechanism 32 (S15),
The full bobbin 3b waits (S16).

When the bobbin 3b is almost full scale, the same operation as described above is automatically repeated, so that the full-length winding material is automatically and continuously generated at regular intervals. Will be obtained.

[0029]

In summary, according to the present invention, the operation of opening and closing the front door and the operation of switching (turning) the terminal cover, which have conventionally been performed manually, can be automatically performed. Labor is greatly reduced, and labor saving and unmanned operation are possible. In addition, since the switching time is shortened and mistakes can be avoided, work efficiency is greatly improved. Further, since it is not necessary for the worker to approach the rotating bobbin or the like, a serious accident such as entanglement can be avoided, and excellent effects such as greatly improved safety can be exhibited.
