Abstract

PURPOSE:To prevent generation of elongation or cutting in an electric wire by furnishing a rotatable flyer having a send-off guide part concentrically with a wire coiling bobbn, and by sending off the wire with rotation of the flyer while the two are in contact. CONSTITUTION:First in operations, an electric wire 5 wound on a bobbin 6 is drawn out from a hole 10a in hood 10 through the periphery side of a flyer 7 to be then set in a wire processing machine B located beside a wire sendoff device A, and said flyer 7 is rotated by a rotary shaft 3 driven by a motor 9. Then this wire processing machine B is put in operation to give the wire a tension, and put it in pressure contact with the lower part 7e of a large-dia. guide wheel 7e of the flyer 7, and then the wire together with flyer 7 is rotated in the direction that the wire during unwinding will be loosened. Thereby application of impact tension to the wire is avoided when it is drawn out to contribute prevention of elongation or cutting.

Description

[Detailed Description of the Invention] The present invention is directed to a system in which the electrocution wound around the bobbin is fed out to the required length when the machine requires it without applying any tension.
The present invention relates to a dispensing device.

As a conventional technique for this S electric wire feeding device, one shown in FIG. 1 is known. That is, it is composed of a rotatable bobbin b set on a frame a and an accumulator C, and the electric current a' that can be completely unwound from the bobbin b is
+1 is rolled on the upper fixed wheel e and the lower moving wheel f of the ゛r cumulator C 18! The process of using the electric wire d in IC-RE7ζshun has reached the stage of processing. The accumulator C is wound around the bobbin, and by turning on and off the force applied by the electric wire d, the lower wheel ゛ moves up and down by 4%.
Turn off the electric motor (
By rotating the bobbin b, the 11'q structure was created to absorb both sides.

However, even with such a design, there is still a considerable amount of tension in the computer d, which is intermittently released based on the operation of the machine g, which operates intermittently, and especially in the fine details. In the production line, elongation and cutting of the wire occurred in 1, which caused the machine to be cleaned up and the quality of the product to be poor.

The present invention overcomes the problems of conventional technical staff, Q, and 7)! Eyes, /
During intermittent operation of the Jll-L machine, the flyer, which is installed coaxially with the bobbin that is recirculating the electric wire, is continuously rotated in the same direction as the wire is being unwound, and when it is not being unrolled, it is rounded and sagging downward. The downward = W contacts the outer periphery of the fryer during the unwinding tension based on the operation of the machine, and rotates together with the #7 fryer and immediately moves to t41!
It is designed so that it can be pulled out, so that no shocking tension is applied to the wire.

An embodiment of the present invention will be described below with reference to the drawings.
A rotation shaft 3 is provided on the stand 2 of the base 1, and the rotation shaft 3
A bobbin 6 on which a wire 5 is wound is placed on the outer periphery of the bobbin 2 via a bearing 4, and is placed on the stand 2. Rotation 4o
A 7-layer 1 is fixed to one end of 1+3 with a nut 8, and a motor 9 is connected to the other end. 10 is electric wire outlet hole 1
It is a hood with 0a and 10.

As shown in FIG. 3, the fryer 7 has a central shaft portion 1a.
A small-diameter support ring 7b is provided via a plurality of support rods IC (!-), and a large-diameter feeding guide ring 7θ is provided via a plurality of support rods 7d to the support ring 7b. In this state, the feeding guide wheel re is connected to the grooves 5 and 1 which are wound around the bobbin 6 at the outer periphery slightly inside the bobbin 6.
They are arranged concentrically with a J1 spacing between them.

The fryer 1 does not necessarily have to be constituted by a ring-shaped member, and in short, it may be a circular outlet guide portion that is shaped approximately the same as the hob and is placed on the outside of the hob.

Due to the above configuration, when using the bobbin 6 and υ crosstalk 5,
Outer circumference 1 of ryer 1 (follow 1j to hole 10 of hood 10)
Set the electric wire processing machine located on the side of the operator and turn on the motor 9 to keep the fryer 7 in a constant rotation state. Then, in this state, the peep fl that was pulled out from bobbin 6 is 5.
The page has fallen to the bottom of the flyer ~ γ due to eye error.

Next, when the electric wire processing machine B makes a wire b, tension is applied to the electric wire 5 pulled out from the bobbi/6, and the mixed wire 5 comes into pressure contact with the upper part of the colonnade feeding guide ring 70 of the flyer 1, and at the same time at: The pig 5 is fed out together with the fryer 1 while rotating in a direction in which the electric wires are unbundled. When the glenoid drawing operation from the line processing device is temporarily stopped, the electric Ivj
15 pieces fell sagging at the bottom of Fryer 1 and 'n'U.

The present invention is constructed as described above, and when the east wire wound on the bobbin is pulled out, no impact-like tension is applied to the wire despite the continuous operation of the machine. It has a latch that can prevent cross-wires from stretching or breaking, and can also eliminate machine stoppage accidents due to wire cuts.
