Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a twisting direction changing device in a twisting machine.

(Prior Art) FIGS. 3 and 4 show a stranded wire machine according to the present invention, and the conventional art will be described with reference to FIG. In the twisting machine 1, the driving side member 2 and the take-up side member 3 are connected by a connecting rod 4, and these assembly structures are rotatably provided.
A flyer 5 is provided between the drive side member 2 and the take-up side member 3, and a plurality of bus bars 6 supplied from the drive side member 2 are capstans (take-off wheels) provided from the flyer 5 to the take-up side member 3. ) 7, it is twisted and wound on the winding drum 8.

In the twisting machine, when changing the twisting direction of the wire, the rotating direction of the twisting machine is changed. However, if you want to use it without changing the feeding position of the busbar, the mounting position of the flyer, the capstan, etc., you need to change the rotating direction of the twisting machine and change the direction in which the busbar is hung on the capstan in order to change the twisting direction. There is.

Therefore, in order to have the function of changing the twisting direction, a switching device for changing the rotation direction of the capstan to the normal direction is required.

Most of the forward / reverse switching devices that change the rotation direction of the capstan are composed of a combination of gears, but this method has a problem that the grease applied to the gears is scattered to stain the wire.

On the other hand, it is possible to change the twisting direction without changing the rotation direction of the capstan, and in this case, it is possible to cross the capstan by crossing the wire material. However, in this method, one capstan must be driven in the idling state for one-sided driving. However, when the capstan is driven on only one side, the contact area with the capstan for giving tensile strength to the twisted wire is smaller than when driven on both sides, so there is the problem that the tensile strength of the twisted wire cannot be increased sufficiently. there were.

(Problem to be Solved by the Invention) The problem to be solved by the present invention is to provide an induction pulley at an intermediate position of a pair of capstans and to freely select the mounting angle of the induction pulley. Accordingly, it is an object of the present invention to provide a twisting direction changing device for a twisting machine that can change the twisting direction of a busbar without changing the rotating direction of the twisting machine.

(Means for Solving the Problem) Means for solving the problem in the present invention is that a driving side member and a take-up side member are connected by a connecting rod, and between the driving side member and the take-up side member. A flyer is provided, and a plurality of busbars supplied from the driving side member are twisted from the flyer through a pair of capstans provided on the take-up side member and wound on a take-up drum. In a twisted wire machine, a guide cylinder for inserting a busbar is provided on a rotating disc provided on the take-up side member, a guide shaft rotatably provided on a support shaft projecting on an annular base plate, and the annular base plate is provided with the guide pulley. Two arc-shaped elongated holes facing each other in the circumferential direction are formed, and the annular base plate is fixed to the tip end portion of the guide cylinder via the arc-shaped elongated holes so that the mounting angle can be changed. By changing the mounting angle, It is characterized in that the capstan on which the busbar from the guide pulley is hung is changed to selectively give the busbar a twisting direction of either left or right.

(Example) FIGS. 1 and 2 show a twisting direction changing device of the present invention, and FIGS. 3 and 4 show a twisting wire machine.

First, in FIG. 3 and FIG. 4, the twisting machine 1 has a rotating disk on the surface facing the driving side member 2 and the winding side member 3, respectively.
9, 10 are provided, and the transmission shaft 11 is installed at a position deviated from the center of the rotating disks 9, 10. Then, the transmission shaft 11 transmits the rotational force linked with the drive unit of the twisting machine 1 by the timing belt 12 mounted between the transmission shaft 11 and the pulley provided on the drive-side rotating disk 9. Also, the capstan 7
Is rotatably provided inside the take-up side rotary disc 10, and the drive shaft of the capstan 7 and the transmission shaft 11 project outside the rotary disc 10 and Timing belt mounted between the pulley installed on the shaft
The rotational force of the stranding machine 1 is transmitted to the capstan 7 by means of 13.

Referring to FIG. 4, the capstan 7 is composed of two members, both of which can be rotationally driven by a chain 15 mounted on a sprocket 14 provided on each capstan 7a, 7b. .

In FIG. 1 and FIG. 2, a guide cylinder 16 for inserting the busbar 6 from the flyer 5 is provided in the central portion of the rotating disk 10, and an induction pulley 17 for supplying the busbar 6 to the capstan 7 is provided. It is provided adjacent to the guide tube 16. The guide pulley 17 has a guide shaft on a support shaft 19 projecting from an annular base plate 18.
It is rotatably attached by a stop shaft 20 in a direction orthogonal to the axial direction of 16. The side edge of the guide pulley 17 is aligned with the center of the annular base plate 18. Further, when the support shaft 19 is set to be slightly shorter as in the embodiment, the annular base plate 18
A cut 21 is formed in the to secure the rotation of the guide pulley 17.

The annular base plate 18 is provided with two arc-shaped elongated holes 22 facing each other in the circumferential direction, and the annular base plate 18 is provided through the arc-shaped elongated holes 22.
Is fixed to the tip of the guide cylinder 16 by a mounting bolt 23, and the guide pulley 17 is fixed so that the inclination angle can be freely changed with respect to the axial direction of the guide cylinder 16.

The embodiment has the above-described structure, and the busbar 6 pulled out from the guide cylinder 16 is sent to the capstan 7a on the right side in FIG. 4 by the guide pulley 17, and then the adjacent capstan 7a.
After reciprocating a plurality of times with respect to 7b, it is wound around the winding drum 8.

Next, when changing the rotation direction of the twisting wire machine 1 and transmitting it in order to change the direction of the twisted wire, the attachment angle between the annular base plate 18 and the guide tube 16 is changed to change the inclination angle of the guide pulley 17. change. That is, the mounting bolt 23 is loosened and the annular base plate 18 is rotated, whereby the inclination angle of the guide pulley 17 is set to the second angle.
In the figure, change from the solid line to the chain line direction. Then,
The bus bar 6 from the guide pulley 17 can be hung on the capstan 7b on the left side of FIG. 4, and is sent to the take-up drum 8 by reciprocating with the other capstan 7a in the same manner as described above. be able to.

In short, the inclination angle of the guide pulley 17 can be changed by rotationally fixing the annular base plate 18, and thereby the twisting direction can be changed.

(Effect of the Invention) The present invention can change the twisting direction given to the twisted wire by so-called one-touch operation by changing the mounting angle of the guide pulley provided at the position where the busbar from the flyer is supplied to the capstan. , A pair of capstans does not require a rotation switching device, both capstans can be rotationally driven, so that sufficient tensile strength can be applied to the twisted wire, and the conventional device can be used without improvement.
