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 stranding machine.

[0002]

2. Description of the Related Art As shown in FIG. 6, a twisting machine 1 comprises a drive side member 2 and a take-up side member 3 which are connected to each other through a connecting rod (not shown) to form an assembly structure. It is rotatably supported by 4. In addition, the bow 5 and the take-up side member are attached to the plurality of wire rods 6 supplied from the drive side member 2 by bridging the bow 5 over the fryer 9 provided in the facing portion of the drive side member 2 and the take-up side member 3. 3 and the capstan 7 are twisted and wound on the winding drum 8.

The bow 5 is formed by bending a strip-shaped plate made of steel or the like into an arch shape, and the wire rod 6 is passed through a wire guide (parts shown in FIGS. 4 and 5 of the present application) attached to the inner peripheral surface at a predetermined pitch. There is. By the way, the rotation speed of the stranding machine is 3
In order to reach 000 to 4000 rpm, an excessive load is applied to the bow 5 during operation.

Since the base end portion of the bow 5 is attached to the twisting machine by bolts, the tightening portion receives a point load by the bolts. Further, the bow 5 is provided with a screw hole for attaching the wire guide, and a plurality of attachment holes including the tightening portion are provided, so that the strength of the bow is lowered.

During operation of the stranding machine, the bow receives a shear load due to centrifugal force, and the wind pressure during operation causes the bow to "slide" and also receive a torsion load. Therefore, an accident occurs in which the bow is missing from the mounting portion.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a flyer bow which is not damaged even when the twisting machine is operated at high speed.

[0007]

Means for solving the problems in the present invention is characterized in that the bow main body of the flyer bow has a structure in which a hole for attachment is not drilled, and more specifically, it is formed into a band shape. A bow main body having notches formed on both side edges of the formed base end and a bow auxiliary plate provided with a projection for engaging with the notches, the bow auxiliary plate is adjacently coupled to the bow main body, and the bow main body and bow A flyer bow is formed by superimposing the back plate on the auxiliary plate, and a plurality of line guides along the center line are arranged side by side on the flyer bow. In the portion where the back plate is overlapped, the line guide is the first guide. It is fixed to the bow auxiliary plate by the holding metal fittings, the line guide is fixed directly to the bow main body by the second guide holding metal fittings in the part without the back plate, and the bow auxiliary plates provided at both base ends of the flyer bow are twisted. It is characterized in that attached by bolts attached to the fryer line machine.

[0008]

Since the bow main body 11 and the bow auxiliary plate 12 are separated, both can freely move in the length direction and the twisting direction of the bow, so that the load is concentrated on the bow mounting portion. This avoids damage to the bow as a result.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partial plan view and bottom view of a bow, FIG. 2 is a part view of the bow, FIG. 3 is a sectional view of a, b, c, d in FIG. 1, and FIGS. FIG.

1 and 2, the flyer bow 10
Is composed of a bow main body 11, a bow auxiliary plate 12 adjacent to the base end of the bow main body 11, a back plate 13 for superimposing and fixing these, a back pressing plate 14, and the like.
Although only a part of the bow main body 11 is shown, the bow auxiliary plate 12 and the back plate 13 are provided at both base end portions.

The bow main body 11 is formed into a strip-shaped plate, and the drive side member 2 and the take-up side member 3 of the stranding machine shown in FIG.
It has a length that can be passed over the fryer 9 provided in the.
Further, semicircular cuts 15 are provided on both side edges of the base end of the bow main body 11. The bow auxiliary plate 12 is composed of two sheets, and is a semicircle that is adjacent to both side edges of the base end of the bow main body 11 and engages with the notch 15 of the bow main body 11 at the base end. Shaped protrusions 16 are formed. The bow auxiliary plate 12 engages the projection 16 with the notch 15 of the bow main body 11 to fit the bow main body 11, and the projection forming portion has a wide width and a narrow width toward the tip. There is. However, the length may be appropriate.

In the embodiment, the bow main body 11 has a total length of 1455 mm, and the bow auxiliary plate 12 has a length of 360 m.
m.

The back plate 13 is a plate that overlaps with the portion where the bow main body 11 and the bow auxiliary plate 12 are joined, and the back holding plate 14 is composed of two sheets and is on the opposite side of the back plate 13. This is a plate that is formed by forming a through groove 17 for a wire rod on it and superposes it. The back plate 13 has about half the length of the bow auxiliary plate 12,
The back holding plate 14 has a length about half that of the back plate 13.

The bow auxiliary plate 1 is provided on both sides of the base end of the bow main body 11.
2 is joined, the back plate 13 is superposed on one surface of the portion, and the back holding plate 14 is superposed on the other surface, and the base end portion of the flyer bow 10 thus assembled is attached to the bolt 1
Attach to fryer 9 by 8. Reference numeral 19 is a bolt hole for the mounting bolt 18 formed in each member.

A plurality of wire guides 20 are attached to the rear surface of the flyer bow 10 assembled as described above, that is, to the surface that is the inside of the arc when it is attached to the stranding machine. The line guide 20, as shown in FIGS.
A half-divided cylindrical body having flanges 21 formed at both ends thereof, and the gutter-shaped groove is a drum-shaped groove 22 having a large diameter at both ends and a small diameter at the center. The wire rod is inserted inside.

In FIG. 1B, the line guides 20 are juxtaposed along the center line of the bow main body 11, and in the portion where the bow auxiliary plate 12 is provided, the first guide retainer having a length reaching the bow auxiliary plate 12 is provided. The metal fitting 23 is abutted, and the part having the back plate 13 fixes the first guide pressing metal fitting 23 and the back plate with a screw 24.
In addition, the part without the back plate 13 is brought into contact with the bow auxiliary plate 12 with the connecting plate 25 and fixed with the setscrews 24 (see FIG. 4). Furthermore, in the portion where the bow auxiliary plate 12 is not provided, the line guide 20 is attached to the second guide holding metal fitting 2
6 is abutted and directly fixed to the bow main body 11 with a set screw 24 (see FIG. 5).

The embodiment has the above-mentioned structure, and the assembled flyer bow 10 is attached to a stranded wire machine, and a wire material as a material of the stranded wire is passed through the wire guide 20. A shear load or a torsion load is applied to the fryer bow 10 during operation, but the bow main body 11 forming the fryer bow 10 has no mounting hole for mounting the stranding machine, and
Since there is a slight gap between the bow auxiliary plate 12,
Both can move freely, which prevents the load from concentrating on the bow attachment and prevents damage to the bow.

Incidentally, since the wire guide 20 is directly attached to the bow main body 11, a screw hole for attachment is provided, but since this portion is far away from the attachment portion, the wire guide 20 is attached during operation. No cracks occur in the part.

[0019]

Industrial Applicability The present invention avoids the concentration of load on the mounting portion by using the flyer bow as an assembled structure, and can prevent damage during operation.
