[Problems to be solved by the device]

 The following problems have been encountered in the operation of handling the wire 3 (hereinafter referred to as a wire) wound around the conventional wire bobbin 2 as described above. For example, while the wire 3 is placed on the workbench 1 and the end of winding the wire 3 is grasped by hand, the hand is moved backward in the winding direction of the wire 3 and the outer circumference of the wire bobbin 2 is circulated. When the wire of the required length is unwound from the wire bobbin 2 and unwound, and the wiring is repeated one after another, according to the required length, the end of the winding of the wire 3 is grasped and the hand holding the terminal side is wound. There was a complicated work operation and annoyance that the wire bobbin 2 had to be wound around the outer periphery of the wire bobbin 2 in the reverse direction of the mounting direction, and the wire of the required length had to be rewound from the wire bobbin 2 and fed out. For this reason, not only a great deal of time is spent on wiring work, but also the upper arm may be fatigued. In addition, recently, a device for continuously cutting the wire 3 into a required length has become widespread. However, even when such a device is used, the wire 3 is manually operated as in the case of the above wiring work. There was a problem that the wire had to be unwound from the wire bobbin 2 and fed out to the device while being unwound.

The present invention has been made in order to solve the above problems, and can rewind a wire wound around a wire bobbin from the wire bobbin at high speed and smoothly and feed it freely in any direction. The purpose is to obtain a wire feeding mechanism.

[0006]

[Means for Solving the Problems]

 The wire payout mechanism according to the present invention comprises a table for placing and placing the wire, and a tubular or spiral flexible body for unwinding the wire from the wire bobbin at high speed and smoothly and paying it out in any direction. It was done.

[0007]

[Action]

 According to this invention, it is provided with a table on which the wire is placed and a flexible body in the form of a tube or spiral for rewinding the wire from the wire bobbin at high speed and smoothly, and unwinding it sequentially in any direction. With this, the wire can be unwound from the wire bobbin at high speed and smoothly, and can be sequentially fed out freely.

【Example】

 Example 1. FIG. 1 is a perspective view showing an embodiment of the present invention, in which 1 is a workbench, 2 is a wire bobbin wound with wire, 3 is a wire wound around the wire bobbin, and 4 is the above. A table 5 on which the wire 3 wound around the wire bobbin 2 is placed is erected on the upper surface of the table 4, and a first column having a through hole in a direction perpendicular to the upper surface of the table 4, A lower end 6 of the second support 6 is slidably inserted into the through hole of the first support column 5 so that it can be fixed at a desired position, and an upper end thereof is bent into a substantially L shape toward the center of the upper surface of the table 4. A column, 7 is fixed to the upper end of the second column 6, and has a flexible body holding member having a through hole in a direction perpendicular to the upper surface of the table 4, and 8 is a through hole of the flexible body holding member 7. , 9 have through holes 8 of the flexible member holding member 7 at the upper end side. Penetrating held is suspended tubular or spiral flexure.

Next, the operation of the above embodiment will be described. First, the wire 3 is placed on the upper surface of the table 4 so that the center of the wire bobbin 2 is located directly below the through hole 8 formed in the flexible body holding member 7. After this, the lower end side is slidably inserted into the through hole of the first support column 5 and the second support column 6 press-fitted so that it can be fixed at a desired position is slid in either the vertical direction or the second support column 6. The lower end side of the flexible body 9 held by the flexible body holding member 7 fixed to the upper end of the wire collides against the upper brim of the wire bobbin 2 and bends, and the tip end of the flexible bobbin 2 extends from the outer circumference of the brim of the wire bobbin 2. Adjust it so that it protrudes to the outside and fix it. Next, the winding end end of the wire 3 is inserted into the hollow portion of the tubular or spiral flexible body 9, and penetrated and drawn toward the upper end side of the flexible body 9. This completes the setting of the wire 3 wound around the wire bobbin 2 on the feeding mechanism.

Next, when the winding end end side of the wire 3 penetrating the flexible body 9 is pulled in a desired unwinding direction, the wire 3 of the flexible body 9 in the portion penetrating to the upper side of the flexible body holding member 7 is When the wire 3 bends in a rounded manner following the winding direction and smooths the passage of the wire 3 that is successively wound, the wire 3 can be freely moved in the same direction. At this time, if it is further continuously pulled, tension acts between the flexible body 9 and the unwinding boundary portion of the wire 3, and the flexible body 9 in the portion below the flexible body holding member 7 is tensioned. The leading end of the wire 3 bends with a roundness in the direction of the unwinding boundary portion of the wire 3 to smoothly pass the wire 3 that is successively fed out, and the wire 3 around the outer diameter of the wire 3 3 is subjected to a tension to circulate in a direction opposite to the winding direction, and the boundary circumference around which the side opening under the through hole 8 of the flexible body holding member 7 and the flexible body 9 contact is fulcrum. By winding around the outer diameter of the wire 3 in the direction opposite to the winding direction of the wire 3, the wire 3 can be unwound from the wire bobbin 2 and smoothly delivered.

Example 2. Although the wire wound around the wire bobbin has been described in the above-described Embodiment 1, a wire material such as a thread or a string wound around the bobbin may be used, and the same effect as that of the above-described embodiment can be obtained. Play.

[0012]

[Effect of the device]

 As described above, the present invention is a mechanism provided with a tubular or spiral flexible body for smoothly rewinding a wire wound around a wire bobbin from the wire bobbin and sequentially paying it out freely in any direction. With this, the wire can be unwound from the wire bobbin at high speed and smoothly, and can be sequentially fed out freely. That is, the hand holding the end of the wire at the end of the wire winding is moved backwards in the winding direction of the wire, and the outer circumference of the wire bobbin is wound around the wire one by one, and the wire of the required length is wound. The complicated work operation of rewinding from the bobbin and unwinding is eliminated, and therefore, there is an effect that the efficiency of wiring work etc. is improved without the upper arm being labored.

Further, when the present invention is used for supplying a wire to a device for continuously cutting a wire, the wire is smoothly rewound from the wire bobbin in conjunction with the operation of the wire automatic feeding mechanism on the device side. Since it is paid out, there is no need to manually feed the wire to the device.
