DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flyer bow for a stranded wire machine, and more particularly to a flyer bow for preventing dirty machine oil or the like from adhering to a wire passage of the bow during operation.

[0002]

2. Description of the Related Art FIG. 1 shows an example of a stranded wire machine to which the present invention belongs. The flyer bow according to the present invention is a band-shaped plate that twists a plurality of wires and is curved in an arch shape, and has both ends attached to a rotating member of a twisting wire machine.

The twisting wire machine 1 is provided with rotating disks 4 and 5 on the front sides of a driving member 2 and a take-off member 3, respectively. The rotating disks 4 and 5 are connected by a connecting rod (not shown). It is an assembly structure. Further, the drive side member 2 and the take-up side member 3
Is provided with a fryer 6, and a pair of fryer bows 7 are exchangeably attached to the fryer 6. The drive-side member 2 and the take-off-side member 3 are both rotatable, and are connected to a rotation drive unit (not shown).

[0004] A winding drum 8 for winding a stranded wire twisted around the inner part sandwiched between the rotating disks 4 and 5 is detachably provided.

Further, a conductive shaft 9 is rotatably provided at a position deviated from the center of rotation on a surface of each of the rotating disks 4 and 5 facing each other. A belt 10 is attached and connected between a pulley provided on the shaft and a pulley provided on the drive-side member 2, and rotates in conjunction with the drive unit of the twisting machine 1.

On the other hand, on a rotating disk 5 provided on the take-off side member 3, a capstan (take-off vehicle) 11 is rotatably provided, and the capstan 11 is connected to a shaft of the capstan and the transmission shaft. 9 are connected by a belt 12 attached to the stranded wire 9 so that the rotational force of the stranded wire machine 1 is transmitted.

When the flyer bow 7 is rotated by the operation of the stranded wire machine 1, the plurality of wires 13 supplied from the drive side member 2 pass through the flyer bow 7 to reach the capstan 11 provided on the take-up side member 3. Stranded wire 1
4 and is wound on the winding drum 8.

The flyer bow 7 is formed by bending a steel strip plate into an arch shape. A wire guide (part 20 shown in FIG. 4) is provided on the curved inner surface at a predetermined pitch. The wire to be combined is fed to the take-off side member through each wire guide.

The length of the flyer bow is 1000 to 180
0 mm is common, and the stranded wire machine is 30 mm / min.
It is operated at 00 to 4000 revolutions. For this reason, centrifugal force is generated in the flyer bow due to high-speed rotation, and contaminated mechanical oil and the like may adhere to the wire passage of the bow.

[0010] Many of the wire passages of the flyer bow have guide grooves formed along their length, and the wire is guided and supplied to the grooves. Since the stranded wire machine rotates at a high speed, most of the mechanical oil attached to the bow is shaken off, but the oil remains attached to the center of the bow. This is because the bow has an arch shape. In addition, according to the experiment of the inventor, it has been confirmed that the oil adheres even when the guide groove is not formed in the wire passage of the bow.

If dirty machine oil adheres to the wire passage of the flyer bow, the oil adheres to the wire passing through the bow, resulting in a poorly-finished stranded wire having reduced commercial value.
Here, there is a demand for the development of a bow that does not allow the machine oil scattered from the stranded wire machine to adhere during operation.

[0012]

SUMMARY OF THE INVENTION An object of the present invention is to provide a flyer bow in which dirty machine oil is prevented from adhering to a wire passage mainly composed of a bow.

[0013]

Means for solving the problem in the present invention is to provide an oil drainage hole at the center of the bow main body, and one or more oil drainage holes are provided. It is characterized by being able to. Further, the oil drain hole is provided at the bottom of a guide groove formed along the length of the bow main body.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 2 and 3, a flyer bow 7 has a length which can be extended over a fryer 6 provided on a drive side member 2 and a take-up side member 3 of a stranded wire machine. The bow main body 70 has a guide groove 71 formed in a curved inner surface in parallel with the longitudinal direction, and mounting holes 72 for fixing to the fryer 6 at both ends.

In the center of the bow main body 70, a plurality of oil drain holes 73 are provided at the bottom of the guide groove 71, and the oil drain holes 73 are the subject of the present invention. In the embodiment, 3
The oil drain holes 73 are provided, but the number of holes is arbitrary as long as it is one or more. However, when one oil drain hole 73 is provided, the oil drain hole 73 is preferably provided at the center of the bow main body 70.

In FIG. 4, reference numeral 20 denotes a plurality of line guides attached along the guide grooves 71 of the bow main body 70. The line guide 20 is composed of a gutter-like member 22 obtained by dividing a cylindrical body having a flange 21 at both ends into two parts, and a holding member 23 which is superposed at right angles to the longitudinal direction of the gutter-like member 22.
The groove width of the gutter-like member 22 is large at both ends and narrow at the center. Further, the holding member 23 has a width capable of abutting between the flanges 21 of the gutter-like member 22, and the gutter-like member 2
An arc-shaped groove 24 having the same radius as the cylindrical portion 2 is formed, and screw holes 25 are provided at both ends. Reference numeral 26 denotes a set screw for fixing the holding member 23.

The wire guide 20 is assembled by superimposing a presser fitting 23 on the outside of the gutter-like member 22, intersects the gutter-like member 22 across the guide groove 71 of the bow main body 70, and then sets the presser fitting 23 to a set screw. Fix by 26. Line guide 2
0 is attached to the bow main body 70 in an appropriate number.
It is attached at intervals of 0 to 60 mm.

The flyer bow 7 to which the wire guide 20 is attached is fixed to the stranded wire machine 1, and the wire rod 1 supplied to the stranded wire machine 1 is
The wire 3 is pulled out of the drive-side member 2 and guided to the flyer bow 7, the wire 13 is passed through the wire guide 20, and is fixed to the winding drum 8 via the capstan 11 of the take-up side member 3.

When the operation of the stranded wire machine 1 is started, the wire rod 13
While passing through the flyer bow 7, the wire is twisted into a stranded wire 14 and wound on the winding drum 8.

During operation of the stranded wire machine 1, centrifugal force acts to cause the machine oil scattered from the stranded wire machine 1 to adhere to the inside of the bow main body 70, but the machine oil is discharged from the oil drain hole 73, thus The wire 13 passing through the groove 71 is not stained.

In another embodiment shown in FIG.
Although there is no guide groove in 0, by providing an oil drain hole 173 also, it is possible to prevent dirty machine oil from adhering to the passage of the wire.

[0022]

According to the present invention, in a stranded wire machine operated at a high speed rotation, dirty machine oil scattered from the stranded wire machine is prevented from adhering to the wire passage of the flyer bow. The stranded wire can be processed without contaminating the wire, and thus has an effect of obtaining a product with high commercial value.
