BACKGROUND OF THE INVENTION
The present invention relates to a continuous winding device and a bobbin switching method for obtaining a bobbin wound wire used as a conductor of an electric wire or cable.
[0002]
[Prior art]
Conventionally, wires such as conductors of electric wires and cables are sent to the continuous winder side while drawing the rough wire obtained by a continuous casting and rolling method or dip forming method to a predetermined diameter by a wire drawing machine, etc. Manufactured from a bobbin winding wire continuously wound on a rotating bobbin.
[0003]
FIG. 4 is a front view showing a basic structure of a conventional continuous winder 1 for obtaining the bobbin winding wire, and FIG. 5 is a plan view thereof.
[0004]
As shown in the figure, the continuous winder 1 alternates between a traverse part 2 for guiding a wire W continuously sent from a wire drawing machine and the like and a wire W sent via the traverse part 2. A pair of bobbins 3a, 3b to be wound around, a pair of arbor shafts 4a, 4b for detachably holding and rotating the bobbins 3a, 3b, and a pair of cutter portions 5a for cutting the wire W when switching the winding. , 5b, a pair of setting roll portions 6a, 6b and a line-feeding roll portion 7 for controlling the passing position of the wire W, a cylindrical terminal cover 8 that alternately covers the bobbins 3a, 3b, and the terminal cover 8 and The guide shaft 9 that moves the drawing roll portion 7 as a unit in the axial direction of the arbor shafts 4a and 4b and the bobbins 3a and 3b are moved from the arbor shafts 4a and 4b side. Is mainly composed respective pair of the unloader section 10a which removably separately from 10b or the like.
[0005]
6 and 7, when the first bobbin 3a around which the wire W is wound is fully wound, the traverse portion 2 located at the upper part of the bobbin 3a moves to the arbor shaft 4b side. If the bobbin 3b held by the arbor shaft 4b starts to rotate in the opposite direction with respect to the bobbin 3a, and then the winding peripheral speeds of both the bobbins 3a and 3b are synchronized, as shown in FIG. Then, after one setting roll portion 6a protrudes and the other setting roll portion 6b retreats, the line-feeding roll portion 7 is moved along with the terminal cover 8 along the guide shaft 9 toward the bobbins 3a and 3b. The line-rolling section 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. Yes. Further, since a pair of guide rods 12 and 12 are provided on both sides of the guide rail 9 so as to be parallel to the guide rail 9, it is possible that the line-rolling portion 7 rotates around the guide shaft 9. On the other hand, the terminal cover 8 is rotatable about the guide shaft 9 toward the arbor shaft 4b.
[0006]
In this way, when the wire drawing roll part 7 is drawn toward the bobbins 3a and 3b, the wire W extending from the traverse part 2 to the bobbin 3a side is further set on the bobbin receiving plate 13b side of the arbor shaft 4b with the setting roll part 6a as a fulcrum. Further, the periphery of the bobbin 3a that has been fully wound is covered by the terminal cover 8 that is pressed against and moved at the same time. Then, caught by the chuck portion 14 b of the wire W is rotated together with the bobbin receiving plate 13b, it is transmitted to the rotating direction together with the chuck unit 14b, pass each other in the cutter portion 5b and fast fixed around the bobbin receiving plate 13b Then, it is wound around the bobbin 3b as it is.
[0007]
On the other hand, the bobbin 3a in which the wire W is cut and thus fully wound is covered by the terminal cover 8 located around the bobbin 3a so that the ends of the wire W are not scattered and entangled with the adjacent empty bobbin 3b or the like. 8 and 9, after the terminal cover 8 returns to the original position and is switched to the other bobbin 3b side, it is removed from the arbor shaft 4a side by the unloader portion 10a. And conveyed outside the winder 1.
[0008]
Then, a new empty bobbin 3a is attached to the empty arbor shaft 4a side, and the terminal cover 8 is rotationally moved to the arbor shaft portion 4b side, and the other bobbin being wound in the process. When 3b is fully wound, the same operation as described above is alternately repeated, so that a bobbin-wound wire having a wound layer of the wire W on the bobbin can be obtained continuously at regular intervals.
[0009]
[Problems to be solved by the invention]
By the way, as shown in FIGS. 8 and 9, a protective measure 15 is provided around such a continuous winder 1 from the viewpoint of ensuring safety, and the bobbin switching operation is illustrated as follows. The front doors 16a and 16b provided in front of the protective measures 15 are directly opened and closed by an operator.
[0010]
For this reason, while the winder 1 is in operation, it is necessary that at least one worker is resident in the vicinity to perform the work, and there is a disadvantage that much labor and labor are required.
[0011]
In addition, the switching operation (rotational movement) of the terminal cover 8 is also performed manually by an operator who opens the full-face doors 16a and 16b. However, since the bobbin is rotating at a high speed in the vicinity thereof, there is a danger. It is also possible to cause a serious accident.
[0012]
Furthermore, manual bobbin switching requires a lot of time to get used to the work, and an unexpected human error is likely to occur during the work, which is often interrupted during the work, resulting in low work efficiency. is there.
[0013]
Therefore, the present invention has been devised to effectively solve such problems, and its purpose is to perform these series of bobbin switching operations automatically and efficiently without relying on human hands. The present invention provides a novel continuous winding device and a bobbin switching method thereof.
[0014]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention alternately winds a wire rod around a pair of bobbins, automatically cuts the fully wound bobbin side wire, and winds the cut wire rod around the other bobbin side. Thereafter, in the continuous winding device in which the periphery of the fully wound bobbin is covered with a terminal cover which is movable in the axial direction and then the fully wound bobbin is taken out by the unloader part, the bobbin is provided in the direction in which the bobbin is taken out. An automatic opening and closing mechanism that automatically opens and closes the front door linked to the unloader part, and a plurality of convex parts on the outer periphery of the spline shaft provided between the bobbins are detected by a turning angle sensor and linked to the unloader part. And a turning movement mechanism for turning the terminal cover around the spline shaft toward the other bobbin. Then, after the front door provided in the bobbin take-out direction is automatically opened and taken out by the automatic opening / closing mechanism, the terminal cover is swung to the other bobbin side with the swivel moving mechanism as an axis between the bobbins. Therefore, a new empty bobbin is attached to the taken-out bobbin side by the unloader section, and then the front door is closed by the automatic opening / closing mechanism.
[0015]
This makes it possible to automatically perform bobbin switching work that has been relied on by hand, that is, opening and closing the front door and switching the terminal cover automatically, reducing the burden on workers, improving safety, and winding. Efficiency of work and switching work can be achieved.
[0016]

The cover 8 can be pivotally moved to one of the arbor shaft portions 4a and 4b. That is, this pivotal movement mechanism 25 includes a splined sprockets 26 are in spline shaft 21, the swing motor 28 fixed to the installation hole 27 of the bottom, while the sprocket 2 6 between the sprocket 26 swing motor 28 side And a rotation angle sensor 31 for detecting the rotation angle of the sprocket 26. The spline shaft 21 is driven by rotating the turning motor 28 in either the forward or reverse direction. one of the arbor shaft portion 4a only the terminal cover 8 rotates as a shaft of the spline shaft 21, and pivotal movement in 4b side, also the terminal by detecting a rotational angle sensor 3 1 at the same time its pivot angle The cover 8 is accurately positioned so as to be coaxial with the axes of the arbor shaft portions 4a and 4b. It has become the jar. The swing motor 28 is automatically controlled by a controller (not shown) linked to a predetermined movement of unloader units 10a and 10b described later.
[0021]
On the other hand, around the arbor shaft portions 4a, 4b, etc., a protective measure 15 made of a wire mesh or the like is stretched to restrict entry of workers, and in front of the bobbin 3a, 3b in the loading / unloading direction. Are provided with sliding opening / closing doors 16a and 16b that are automatically opened and closed by automatic opening and closing mechanisms 32 and 32, respectively. The automatic opening / closing mechanism 32 includes an actuator 33 such as a hydraulic cylinder that opens and closes the open / close doors 16a and 16b, and an open / close sensor 34 that detects the movement of the unloader portions 10a and 10b located outside the open / close doors 16a and 16b. 34 (light receiving element and light emitting element), and the movement of the unloader portions 10a and 10b is detected by the opening and closing sensors 34 and 34 to automatically open and close the opening and closing doors 16a and 16b. . That is, when the unloader portions 10a and 10b are driven at the time of bobbin switching, the open / close doors 16a and 16b are opened, and when the bobbin switching is finished and waiting for full winding, the opening of the protective measure 15 is closed to close the unloader. The safety of the apparatus is ensured without hindering the movement of the parts 10a and 10b.

[0023]
Next, an embodiment of the bobbin switching method by 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).
[0024]
First, if the left bobbin 3a is close to full scale in the state shown in FIG. 1 (S1), the traverse part 2 located above is moved to the right bobbin 3b side (S2) and The bobbin 3b is started to rotate (S4) and its peripheral speed is synchronized with the peripheral speed on the bobbin 3a side (S4).
[0025]
Next, if the peripheral speeds of the bobbin 3a and the bobbin 3b are synchronized, the drawing roller 11 draws the drawing roller 7 and the terminal cover 8 along the spline shaft 21 to the bobbin side (S5), as shown in FIG. As in the conventional example, the setting rollers 6a and 6b are operated to cut the wire W, and the bobbin 3b side winding is started by engaging the upstream end of the cutting with the chuck portion 14 (S6). At the same time, the rotation of the bobbin 3a is stopped, but the periphery of the bobbin 3a is covered with the terminal cover 8, so that the end of the wire W is broken and entangled with the other bobbin 3b, The inconvenience of being caught on the shaft 21 or the like is prevented.
[0026]
Next, the drawing cylinder 11 is extended to move the drawing roller 7 and the terminal cover 8 to their original positions (unloader 10a, 10b side) (S7), and then the turning drive mechanism 25 winds only the terminal cover 8. The bobbin 3b on which removal is performed is turned (S8). Since the turning angle is monitored by the turning angle sensor 31, the terminal cover 8 that has been turned and moved is accurately stopped at a fixed position so as to be coaxial with the bobbin 3b (S9).
[0027]
If the terminal cover 8 is avoided on the bobbin 3b side in this way, the setting rollers 6a and 6b return to their original positions (S10), and the front door 16a on the bobbin 3a side is opened by the automatic opening / closing mechanism 32 ( S11), the unloader portion 10a located on the front surface thereof advances to the bobbin 3a side, stops at the lower portion of the bobbin 3a (S12), removes the bobbin 3a from the urban shaft 4a, and directly conveys it outside the front door 16a. (S13), a new empty bobbin 3a is attached to the original urban shaft 4a side (S14), and after returning to the original position again, the automatic opening / closing mechanism 32 is stopped. As a result, the front door 16a is closed (S15), and the other bobbin 3b side waits for full scale (S16).
[0028]
And if this bobbin 3b side becomes near full scale, the winding material which became full scale for every fixed time can be obtained automatically and continuously by repeating the same operation as the above automatically. become.
[0029]
【The invention's effect】
In short, according to the present invention, since it is possible to automatically perform the front door opening and closing work and the terminal cover switching (turning) work, which has been performed manually, the labor of the worker is greatly reduced. Therefore, labor saving and unmanned work are possible. Moreover, since the switching time is shortened and mistakes can be avoided, the work efficiency is greatly improved. Furthermore, since it is not necessary for the worker to approach the rotating bobbin or the like, it is possible to avoid a serious accident such as entrainment and to exhibit excellent effects such as greatly improving safety.
