Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coaxial type wire stranding device in which a bobbin and a flyer are coaxially arranged, and cannot be removed and replaced in normal wire stranding operations.

[Prior art]

Traditionally, multiple wires are wound around a single bobbin, and a flyer rotates to pull out the wires from the bobbin, and then the wires are separated into individual wires and then twisted. It is known to carry out the twisting operation, to pull out the wires from the bobbin for twisting, and when the bobbin becomes empty, to remove the empty bobbin, install a new full bobbin, and continue the twisting operation. An example of a wire twisting device that performs such twisting is shown in Figure 2.

In the figure, 11 is a bobbin, 13 is a flyer, 15 is a bobbin rotation shaft, 17 is a flyer rotation shaft, 19 is a bearing of the bobbin rotation shaft 15, 21 is a bearing of the flyer rotation shaft 17, and 23 is a bobbin rotation shaft 15
25 is a timing pulley that rotates the fryer rotating shaft 17 (or applies a brake to the rotating shaft 15), 27 is a batten, and 29 is a twist cap. A plurality of linear bodies are wound around the bobbin 11 in advance, and the flyer 1
The plurality of linear bodies 31 pulled out from the bobbin 11 by the rotation of step 3 pass through the guide die 33,
After being separated into individual linear bodies 31a, they are passed through a batten 27 and twisted together using a twisting nozzle 29.

Further, if necessary, both or one of the bobbin rotating shaft 15 and the flyer rotating shaft 17 are moved in and out using a structure not shown, and the bobbin 11 is replaced.

〔assignment〕

In this type of coaxial type stranding device, when a plurality of linear bodies 31 are drawn out from the bobbin by rotation of the flyer, the drawing position of the linear bodies 31 swings within the range indicated by the dotted line. If this deflection angle θ is too large, it becomes difficult to draw out the linear body 31 smoothly,
This may cause wire breakage. For this reason, in the conventional device, the rotation radius of the flyer 13 is almost determined by the interval and diameter of the flanges 11a and 11b of the bobbin 11, and it is necessary to reduce the rotation radius of the flyer, that is, to increase the rotation speed of the flyer. There was a limit to speeding up.

[Means for solving problems and their effects]

An object of the present invention is to provide a new type of coaxial type twisted wire device that solves the problems of the prior art as described above.

In order to achieve this purpose, the present invention coaxially arranges a bobbin on which a plurality of wire bodies are wound and a flyer rotating around the bobbin, and the bobbin cannot be removed by normal wire twisting work. As a result, the bobbin is not damaged due to replacement, there is no risk of imbalance, and the bobbin can be rotated at high speed. Further, in order to reduce the rotation radius of the fryer in order to achieve high-speed rotation of the fryer, a partition plate is provided between the collar plates at both ends of the bobbin to divide the space between the collar plates into a plurality of parts. .

In this way, the linear object can be wound into each of the multiple spaces divided by the partition plates, so the deflection angle of the linear object drawn out from each winding space is assumed to be the same as the interval and diameter of the bobbin's collar plate. This makes it much smaller than before, making it possible to reduce the rotation radius of the fryer.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG.

In FIG. 1, parts corresponding to those in FIG. 2 are given the same reference numerals. In FIG. 1, the inner end of the flyer rotating shaft 17 is inserted into the inner end of the bobbin rotating shaft 15, and is relatively rotatable via a bearing 35. Further, the rear end portion of the flyer 13 is rotatable on the bobbin rotating shaft 15 by a bearing 37.

The feature of this wire twisting device is that the winding drum 1 of the bobbin 11
A plurality of (five in the illustrated example) partition plates 39 are provided at equal intervals between the collar plates 11a and 11b located at both ends of 1c (inner end of the bobbin rotating shaft 15). The diameter of each partition plate 39 is the collar plate 11a, 11b.
It is the same as As a result, the collar plates 11a and 11
The space between b is divided into six winding spaces 41, and a linear body can be wound into each of them.
That is, the flyer 13 is stopped and the rotating shaft 15 is
In each winding space 41 formed by the bobbin 11 integrated with the bobbin 11, a linear body may be wound one by one by driving the rotating shaft 15 independently, or a plurality of linear bodies may be wound into each winding space 41 formed by the bobbin 11 integrated with the bobbin 11.

The linear body wound in each winding space 41 is pulled out by the rotation of the flyer 13, and the linear body is drawn out by the rotation of the flyer 13.
3, the wire is guided forward and the twisting is performed. Since the deflection angle θ at the time of drawing is significantly smaller than the conventional one by providing the partition plate 39, the rotation radius of the fryer 13 can be reduced accordingly.An additional feature of the present invention is that the bobbin 11 Since the bobbin cannot be removed and replaced during normal wire twisting work, the bobbin is not damaged, the cause of imbalance is eliminated, and this greatly contributes to speeding up the wire twisting device. After the twisting process is completed, this wire twisting device performs residual wire treatment in the same manner as the conventional device, and then, while the flyer rotating shaft 17 is stopped, a linear body (not shown) installed outside the wire twisting device is fed out. The bobbin shaft 15 is rotated by a device and a traverse device (not shown), and the bobbin 1
Preparation for the twisting work is carried out by simultaneously winding the required number of linear bodies into a space 41 divided by one partition plate 39.

Although not shown, the drive device for the flyer 13, the bobbin rotating shaft 15, and the braking device for the bobbin 11, which is integrally formed with the bobbin rotating shaft 15, are not shown in the drawings. Naturally, they are arranged via the pulley 25 and, with respect to the bobbin 11, via the timing pulley 23.

[Effect of idea]

As explained above, according to the present invention, by dividing the space between the flanges at both ends of the bobbin into a plurality of parts using partition plates, it is possible to reduce the deflection angle when drawing out the linear object from the bobbin by rotation of the flyer. The rotational speed of the fryer can be increased by reducing the rotation radius of the fryer. Furthermore, since the bobbin can be attached to a strong bobbin shaft that cannot be removed during normal work, eccentric rotation of the bobbin can be prevented, and stable high-speed rotation of the bobbin can be obtained. Next, since the wire twisting device itself is used to wind the wire into the bobbin, there is no need for the large number of bobbins required for bobbin replacement work found in conventional devices, as well as the stockyards or expensive automated warehouses required for them. Become. Also, due to the function of the partition plate, it is possible to wind multiple wires one by one into one bobbin and pull them out, and since the shape is one bobbin, the drive system can be used as one bobbin. Since the control system can be configured, an inexpensive and highly productive twisted wire device can be realized.

Furthermore, in the past, the wire twisting device and the bobbin size were inseparable, and the bobbin size, including the wire twisting device and its peripheral equipment, was usually unified into one size, and this caused time. Over time, it becomes cancerous and becomes a major factor hindering productivity and varieties. However, with the wire twisting device of the present invention, even when a large number of devices are installed, it is possible to appropriately select the bobbin size within the wire twisting device according to the product of each device, which is expected to improve productivity unprecedentedly. It can be done. This also applies to the expansion of the wire twisting device, and the wire twisting device has the great advantage of being able to select the bobbin size regardless of the conventional factory bobbin size, and is a high performance wire twisting device.
