Abstract

PURPOSE:To stably keep the tension of a linear material pulled out of a bobbin and to prevent the wire from being broken by controlling the driving force or the braking force from the outside by an equipment wherein bobbins are fitted coaxially on a static shaft and a flier is rotated around the shaft. CONSTITUTION:The bobbins 13A which rotate centering the static shaft 11 are fitted to it and the flier 15 which rotates around the bobbins are fitted. The linear material 39 is pulled by the rotation of the flier 15 out of the bobbins 13A, etc., enters an stranding mouthpiece 47 to be stranded around the external circumference of a core wire. A transmission shaft 53A, etc., are inserted corresponding to these bobbins from one end of the static shaft 11 into the static shaft 11, and this transmission shaft 53A, etc., and the corresponding bobbin are connected through a rotating transmission member. A rotating transmission member is fitted to the external end of this transmission shaft 53A, etc., and connected with a torque motor 67A, etc. Hereby, the driving force and brake force of the bobbin are controlled from the outside and the tension added to the linear material 39 is kept to a nice level and breaking of wire and excessive tension can be removed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an apparatus for twisting a large number of linear bodies together or winding them around a core wire. 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 explanation, we will mainly explain the twisting device.
The wrapping device is also similar.

[Prior art and its problems]

Conventional twisting devices attach a large number of bobbins to a cage in a balanced manner in the circumferential direction, rotate the cage,
A typical type is one in which a wire body pulled out from a bobbin is twisted around the outer periphery of a core wire (single wire or stranded wire) that has passed through the center axis of the cage.

However, this type of twisting device has the drawback that the cage swings around the bobbin located away from its center, which creates a large centrifugal force and prevents high-speed operation.

As an improved twisting device,
As seen in Publication No. 7074, a bobbin wound with a linear body is supported so that the core wire passes through the center of the bobbin, and a flyer is rotated around the bobbin to collect the linear body drawn out from the bobbin. Also known are those in which the core wire is twisted around the core wire passing through the center of the bobbin.

However, in this type of twisting device, the number of rotations of the bobbin is the sum of the number of rotations of the flyer and the number of rotations associated with sending out the linear body, so compared to a normal cage type twisting device, the number of rotations of the bobbin is The rotation speed becomes extremely high.

For this reason, in this type of twisting device, it is necessary to rapidly increase the bobbin rotation speed when starting, and to rapidly decrease the bobbin rotation speed when stopping. However, in conventional devices, the bobbin and flyer are simply connected via a mechanical brake, so in order to rapidly increase or decrease the bobbin rotation speed, the braking force must be set quite strong. As a result, extremely high tension is applied to the wire body drawn out from the bobbin, and problems such as wire breakage and excessive tension are likely to occur.

[Means for solving problems and their effects]

An object of the present invention is to provide a device for twisting and winding linear bodies that solves the problems of the prior art as described above.

To achieve this objective, the present invention provides a stationary shaft with a bobbin attached to it so as to be rotatable about it, and
A flyer is attached so that it can rotate around the bobbin, and then a transmission shaft is inserted from one end of the stationary shaft into the stationary shaft corresponding to the bobbin, and the transmission shaft and the corresponding bobbin are rotated. While connecting via a transmission member,
It is characterized in that a rotation transmission member is attached to the outer end of the transmission shaft.

In this way, by connecting a torque motor, an electromagnetic clutch, etc. to the rotating transmission member attached to the outer end of the transmission shaft, the driving force and braking force of the bobbin can be freely controlled from the outside. This makes it possible to maintain the tension applied to the linear body at a desirable level from start to stop.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 and 2.

In the figure, 11 is a stationary shaft, 13A to 13D are bobbins,
15 is a fryer.

The stationary shaft 11 is hollow, and large diameter portions 17A to 17D are formed at predetermined intervals in the longitudinal direction on the outer periphery of the intermediate portion, and the bobbins 13A to 13D are formed in the large diameter portions 17, respectively.
It is rotatably supported by A-170 via a bearing 19. A similar large-diameter portion 21 is also formed at one end of the stationary shaft 11, and that portion of the stationary shaft 11 is fixedly supported by a support frame 23, so that the stationary shaft 11 is always maintained in a stationary state.

Further, a flyer 1 is provided in the large diameter portion 21 on one end side of the stationary shaft 11.
One end side of 5 is rotatably attached via a bearing 25. A boss portion 27 is provided protruding from the other end of the flyer 15, and this boss portion 27 is rotatably supported by a support frame 31 via a bearing 29. Further, the other end side of the stationary shaft 11 is supported within the boss portion 27 via a bearing 33. There are synchronized boots IJ35 on both ends of the flyer 15.
．． 37 are attached, and when these are simultaneously driven to rotate from the outside, the flyer 15 is attached to the bobbins 13A to 13D.
It will rotate around.

The linear body 39 pulled out from the bobbins 13A to 13D by the rotation of the flyer 15 passes through a guide roll 41 inside the flyer 15, passes through a pull-out hole 43 formed in the boss portion 27, and then passes through a guide roll 45 outside the flyer 15. The fibers pass through the twisting cap 47 and are twisted around the outer periphery of the core wire 49.

On the other hand, in the large diameter portions 17A to 17D and 21 of the stationary shaft 11, shaft holes 51A to 51D (first
In the figure, 51B and 51C are omitted; the same applies hereinafter) are formed, and transmission shafts 53A to 53D that reach the corresponding bobbins 13A to 13D from one end side are inserted into each shaft hole 51A to 51D. The transmission shafts 53A to 53D are supported at both ends by bearings 55 and 57 and are parallel to the stationary shaft 11, and each of the transmission shafts 53A to 53D has a small gear 59A to 59D at its inner end.

10 is a synchro belt 65A to 6 as shown in FIG.

That is, each bobbin 13A to 13D has internal gears 63A to 63D1 pinion gears 59A to 59D1 and transmission shaft 53A.
~53D1 Since the driving force or braking force can be individually controlled by the torque motor or electromagnetic clutch 67A-67D connected via synchro pulleys 61A-61D and synchro belts 65A-65D, each bobbin 13A- Linear body 3 pulled out from 13D
9 can be given stable tension.

In addition, if a bobbin drive motor is connected to the synchronized pulleys 61A to 61D, the flyer 15 can be stopped and only the bobbin can be rotated, so when the bobbin is empty, the linear object can be removed from the bobbin. It is also possible to involve.

〔Effect of the invention〕

As explained above, according to the present invention, the bobbin is attached coaxially to a stationary shaft, and the bobbin driving force or braking force is externally controlled in a twisting/winding device in which a flyer is rotated around the bobbin. As a result, the tension of the wire drawn from the bobbin can be maintained stably, allowing smooth startup and stopping, as well as preventing wire breakage and
Troubles such as overtension can be eliminated.
