Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a device for twisting a large number of linear bodies together or winding them around a core material. The linear body mentioned here includes wire rods such as electric wires and metal wires, as well as strips (tape), strings, tubes, and the like.

In the following description, the twisting device will be mainly explained, but the same applies to the winding device.

[Prior art and its problems]

Conventionally used twisting devices are equipped with a bobbin wound with wires and twisted, and when the bobbin becomes empty, the empty bobbin is replaced with a fully wound bobbin, and the twisting process is continued. I'm starting to do it. For this reason, it is necessary to stop the operation of the twisting device while replacing the bobbin, and there is a limit to improving the operating rate of the device.

As a twisting device that does not require bobbin replacement, a device called a SKET type is conventionally known. This is a hollow rotating shaft, and a large number of pairs of bobbins are provided in the longitudinal direction of the rotating shaft, coaxially and rotatably relative to the hollow rotating shaft, and between the two bobbins of each set, Each bobbin is equipped with a flyer that unwinds the wire from the bobbin.The flyer pulls out the wire from one of the bobbins in each set, and guides the drawn wire through the rotating shaft to one end where it is unwound. While twisting is performed, the other bobbin from which the linear body is not drawn out is rotated by an external drive to wind up the linear body.

In other words, this twisting device consists of two bobbins, and while the wire is pulled out from one bobbin and twisted, the wire is wound into the other bobbin, and one bobbin is twisted. When the bobbin is empty, the wire is pulled out from the other bobbin that has been wound and twisted, and this process is repeated to perform twisting almost continuously.

However, this twisting device has the following problems. That is, since a flyer is provided for each pair of bobbins, the structure becomes complicated and the price becomes high. Furthermore, since the length of the rotating shaft becomes long, the so-called wire threading operation, in which the linear body pulled out from the bobbin is pulled out to one end through the hollow part of the rotating shaft, is troublesome and the workability is poor.

Therefore, the present inventor first provided first and second hollow shafts on the central rotating shaft, attached a plurality of bobbins to each of them, and while twisting was being performed on one, the empty bobbins on the other were being twisted. We proposed a twisting and winding device for linear objects that can wrap linear objects (Japanese Patent Application No. 231311/1982). This device can shorten the overall length of the device, simplify the structure, and has one half of the central rotating shaft as a large diameter section and the other half as a small diameter section, so that there are many Since the wire guide hole is formed, there is an advantage that the wire threading operation can be easily performed.

However, in the case of this device as well, although a large number of linear object guide holes are formed in the central rotating shaft, it is necessary to pass the large number of linear objects one by one through the guide holes. It is still insufficient in terms of labor saving. There is also a risk that the linear body may come into contact with the inner surface of the guide hole, causing scratches or breakage. Furthermore, although the length of the central rotation axis is shorter than before,
However, it still requires a length sufficient to penetrate the first and second hollow shafts, each of which supports a plurality of bobbins, and the diameter of the central rotating shaft must be increased for strength reasons. and the diameter of the second hollow shaft and the bearing supporting it are increased,
As a whole, there are problems such as an increase in size in the radial direction and a limited number of rotations.

[Means for solving problems and their effects]

The present invention provides a device for twisting and winding linear bodies that solves the above-mentioned problems, and consists of a bobbin supported on a rotating shaft, and a bobbin that rotates around the bobbin. A pair of linear object supply units consisting of a flyer that pulls out a linear object from a bobbin are arranged on the same axis so that the drawing ends of the linear objects are on the inside, and between the pair of supply units, A part for twisting or winding the wire-like bodies is provided, and the long body twisted or wound there is pulled out through the shaft hole of one supply unit to the outer end of that supply unit. It is characterized by this.

This device eliminates the need to thread each individual wire by twisting or winding the wire between a pair of wire supply units and passing the completed long body through the shaft hole. This prevents scratches and wire breaks caused by the linear body coming into contact with the inner surface of the guide hole. Furthermore, by dividing the linear body supply unit into two and shortening the length of the rotating shaft, the diameter of the rotating shaft is reduced, the overall size is reduced, and the speed is increased.
