A braking device urged to press against the outlet pipe is provided.
Because the rotation of the rotating shaft due to inertia is suppressed, even if the wire is pulled out intermittently, the flyer does not rotate more than necessary due to the inertial force, and the wire is loose and entangled And the like can be prevented, and the electric wire can be led out in a stable state.

[0009]

FIG. 1 is a partially cutaway front view showing an embodiment of an electric wire feeding apparatus according to the present invention. The electric wire feeding device A includes a flyer 1, a support member 2, a braking device 3,
It is constituted by the.

In the flyer 1, the rotating shaft 4 rotates around the supporting member 2.
An electric wire guide arm 5 is attached to one end of the rotating shaft 4 while being rotatably supported, and a loop-shaped electric wire guide 6 is attached to a distal end portion thereof. The other end of the rotary shaft 4 is a hollow wire guiding tube 7 is provided on the extension line of the rotation shaft 4, the support member 2
The flyer 1 is rotatably supported by inserting the electric wire lead-out tube 7 into the bearing 8 attached to the flyer 1. As shown in FIGS. 2 and 3, a pulley-shaped guide roller 9 is rotatably provided at an intermediate portion of the rotating shaft 4, and the electric wire 1 drawn through the electric wire guide 6 of the electric wire guide arm 5 is provided.
0 is smoothly introduced into the electric wire outlet pipe 7.

An electric wire lead-out plate 13 is installed above an electric wire shelf 12 on which a cassette reel 11 around which electric wires 10 are wound is arranged.
And the support member 2 is attached to the wire lead-out plate 13.
However, in this case, the rotating shaft 4 supported by the support member 2
Is fixed so as to coincide with the winding shaft 11a of the cassette reel 11 (see FIG. 1).

The braking device 3 is a constant brake attached to the support member 2 for suppressing the rotation of the flyer 1. The structure of the braking device 3 includes a braking element 14 as shown in FIG.
A structure that is always pressed against the outside of the electric wire lead-out pipe 7 by a spring 13
It is.

Next, the state in which the electric wire 10 is fed out by the above-described electric wire feeding device A will be described. The terminal of the electric wire 10 pulled out from the cassette reel 11 is passed from the lower side to the upper side of the electric wire guide 6 of the electric wire guide arm 5,
Further, it is led out above the rotating shaft 4 through the wire guide roller 9 and the wire lead-out pipe 7.

In general, an electric wire processing apparatus that receives supply of electric wires from a cassette reel is often operated intermittently, and therefore, the operation of feeding out the electric wires is also performed intermittently. Therefore, immediately after the wire is pulled out, the wire is excessively supplied by the inertial force and the phenomenon of slack occurs. However, by suppressing the inertia force of the flyer 1 by the braking device 3, the wire 1
Zero slack can be suppressed to a minimum, and it becomes possible to prevent the entanglement and kink of the electric wire. In addition, the wire feeding device of the present invention can be used for feeding not only a single wire but also a plurality of wires from a cassette reel wound with a bundle of wires bundled together.
