Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fryer bow for a twisting machine.

[0002]

2. Description of the Related Art In a twisting machine, as shown in FIG. 8, a driving side member 1 and a take-up side member 2 are connected to each other through a connecting rod (not shown) to form an assembly structure. It is rotatably supported by 3. Further, by bridging the flyer bow 4 between the driving side member 1 and the take-up side member 2,
The plurality of wire rods 5 supplied from the driving side member 1 are twisted while passing through the take-up side member 2 and the capstan 6 from the flyer bow 4 and taken up by the take-up drum 7.

On the other hand, as shown in FIG. 9, the flyer bow 4 is formed by bending a strip plate represented by steel or the like into an arch shape, and a guide groove 8 for guiding the wire 5 is provided with this strip plate. By forming the wire rod 5 on the inner peripheral surface of the flyer bow 4, the wire 5 is slidably held by the guide groove 8 and a die attached to the inner peripheral surface of the flyer bow 4 at a predetermined pitch. I am trying. Further, by cutting the outer peripheral edge of the fryer bow 4 into an arc shape to form an edge 9 on the inner peripheral edge, the wire rod 5 hanging down due to disconnection or the like is cut at the edge 9 to prevent damage to the flyer bow 4 due to disconnection or the like. I try to prevent it.

By the way, if the entire flyer bow 4 is made of metal, the weight of the flyer bow 4 becomes large. Further, the rotation speed of the flyer bow 4 reaches 3000 to 4000 rpm, though it varies depending on the twisting machine, so that if the weight of the flyer bow 4 is large, the load on the main spindle becomes large.

If the wall thickness of the flyer bow is reduced in order to reduce the load on the main shaft and the weight is reduced, the flyer bow is likely to vibrate with rotation, and the guide function of the wire rod deteriorates. Also, when the flyer bow is made of fiber reinforced plastic, the cutting action by the edge is not performed, so the wire rod is wrapped around the flyer bow at the time of disconnection, or the flyer bow itself is damaged by collision with the broken wire rod. There is a defect. In addition, the weight has been reduced and vibration has worsened.
Simply layer metal and fiber reinforced plastic to prevent
Although a combined configuration has been proposed (for example, in actual exploitation Sho 57-
No. 150595), the problem with the above cutting action is solved
Not decided.

[0006]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a flyer bow that reduces the load on the main shaft by reducing the weight of the flyer bow without deteriorating the cutting function of the broken wire or deteriorating the vibration. Is to provide.

[0007]

Means for Solving the Problems In the present invention, a means for solving the problems is to apply a hard resin plate on the surface of a flyer bow body formed by bending a metal strip plate in an arch shape.
It is characterized in that the flyer bow main body is laminated and fixed so that the side edge corners of the main body protrude .

[0008]

The strength of the fryer bow 10 is secured by the metal strip. Further, since the hard resin plate 12 is laminated and fixed on the surface of the flyer bow main body 11 , this resin plate
The rigidity of the flyer bow 10 is secured by 12 . Therefore, compared with the conventional flyer bow which is entirely made of metal, the weight can be significantly reduced without lowering the rigidity which has a great influence on the vibration resistance. In addition, the flyer bow body 11 is a metal strip plate ,
Since the corner portion 11a is configured to project , the side end angle of the flyer bow body 11 can be applied to the broken wire rod.
The part 11a has a cutting action. For this reason, a cutting function substantially equivalent to that of a conventional flyer bow, which is entirely made of a metal plate, is exerted on the broken wire.

From the front, FIG. 3 is a cross-sectional view showing the assembled state of the die,
4 is a side view of FIG. 3, FIG. 5 is a perspective view of a die and a die holder, FIG. 6 is a sectional view showing a second embodiment of a fryer bow according to the present invention, and FIG. 7 is a third view of a fryer bow according to the present invention. It is sectional drawing which shows an Example.

In these figures, the flyer bow 10
Is composed of a flyer bow body 11 formed by bending a metal strip plate in an arch shape, and a hard resin plate 12 laminated and fixed on the outer peripheral surface and the inner peripheral surface of the flyer bow main body 11. In addition, the resin plate 12 is adhered or molded to the surface of the flyer bow main body 11 to attach the flyer bow main body.
The side edge corners 11a of 11 are laminated and fixed so as to project .

A guide groove 13 having an arcuate cross section along the length direction of the flyer bow 10 is formed in the central portion of the resin plate 12 laminated and fixed on the inner peripheral surface of the flyer bow body 11. In addition, a die 14 is provided on the inner peripheral surface of the flyer bow 10.
This die 1
A wire rod (not shown) is slidably held by 4 and the guide groove 13.

On the other hand, by rounding the corners of the resin plate 12 laminated and fixed on the outer peripheral side and the inner peripheral side of the flyer bow body 11 to make the cross section of the flyer bow 10 as a whole oval, The fryer bow 1 is provided with a side end corner portion 11a of the fryer bow body 11 composed of a strip plate.
The side edge of 0 is projected.

As shown in FIG. 5, the die 14 is formed of a gutter-shaped member having flanges 15 formed at both ends and a drum-shaped groove 16 penetrating the central portion thereof. A die holder 17 superposed on the surface of 14 is fastened and fixed to the fryer bow 10 with a screw 18.

The flyer bow having the above-described structure has a flyer bow body 11 that bears strength and a hard resin plate 1 that reinforces the rigidity of the flyer bow body 11.
Since it is composed of a laminated body with No. 2, vibration during rotation is suppressed although the weight is reduced. Further, in order to cut the wire rod in which the side end corners 11a of the flyer bow body 11 are broken, there is no damage due to the winding of the wire rod hanging down due to the wire breakage like the flyer bow made entirely of fiber reinforced plastic, or Damage due to collisions with is avoided.

In the above embodiment, the flyer bow 10 is used.
Has an oval cross section as a whole, but the width of the resin plate 12 is made smaller than the width of the flyer bow body 11 as in the second embodiment shown in FIG.
It is also possible to project the entire side end in advance to further improve the cutting function for the wire.

Further, the resin plate 12 is not necessarily laminated on the outer peripheral surface and the inner peripheral surface of the flyer bow main body 11, but only the outer peripheral surface of the flyer bow main body 11 as in the third embodiment shown in FIG. 7, for example. Laminate and fix the resin plate 12 on the
Alternatively, although not shown, the resin plate 12 may be laminated and fixed only on the inner peripheral surface of the flyer bow body 11.

[0018]

According to the present invention, since the hard resin plate is laminated and fixed on the surface of the flyer bow body which bears the strength, the rigidity of the flyer bow body is reinforced by this resin plate. Weight can be reduced without reducing the rigidity of the bow and the load on the spindle of the twisting machine can be reduced. In addition, the present invention provides a wire rod which is entirely made of fiber reinforced plastic and hangs down due to the wire breakage in order to perform a cutting action on the wire rod whose side end corners of the flyer bow body are broken. There is no damage due to winding of the wire, or damage due to collision with the wire is avoided.
