Next, FIG. 10 shows a basic flow of wire rewinding processing using the above-mentioned apparatus. Hereinafter, a method of using the above device will be described with reference to FIG.

The supply drum 3 and the take-up drum 4 are set on the supply-side and take-up-side drum stands 1 and 2, respectively, and the wire rewinding process is started (step S ₁ ,
S ₂ , S ₃ ). When the preparation of each device on the line is completed (steps S ₄ and S ₅ ), both stands 1 and 2 start unwinding and winding (steps S ₆ and S ₇ ). detector 44a cable head pauses are detected (step S _8, S _9), resumes unwinding and dismantle banding unwinding end by hand (step S _10, S _11).

The tip of the electric wire 5 is a guide 18, and the entrance side band is hooked.
Passing through the cutting device 7, the entry side end face processing device 9 and the cutting machine 11
When reaching the length measuring machine 12, the electric wire tip by the detector 44e
The length measurement starts when the edge is detected, and the tip standby position
It is detected by the detector 44f at the 12 output side position and the electric wire is sent.
Is suspended (step S₁₂, S₁₃, S₁₄，
S ₁₅).

[0030] In the take-up stand 2 detector 44j by the drum MakiHajimekuchi 4b position is detected winding is stopped temporarily waits (step S _16, S _17). When the standby signals of both are aligned (step S ₁₈ ), the supply side restarts driving (step S ₁₉ ), and when the tip of the electric wire reaches the position of the output side band hooking device 15, it is detected by the detector 44 h (step S ₂₀ ). The feeding is stopped (step ₂₁ ), and then the feeding-side strapping device 15 is operated to bind the binding band 34 to the tip of the electric wire 5. After that, unwinding is restarted again, and when the wire tip passes through the guide 19 and reaches the position of the winding start port 4b of the winding stand 2, this is detected by the detector 44j, the unwinding is temporarily stopped, and the drum stand 2 is Move closer to the electric wire movement path,
As shown in FIG. 7, the end of the binding band 34 at the tip of the electric wire 5 projects from the drum winding start port 4b, the bending device 40 operates to bend the end of the binding band 34, and the band fixing device 36 operates to bind the band. The end of the band 34 is fixed to the flange portion 4a, and the unwinding and winding of the electric wire 5 is restarted. Step S ₂₂ shown as a tip processing in FIG. 10,
The operations from strapping to bending the band end and fixing the band end are collectively referred to.

The winding recombinant operation of the electric wire 5 is continued in this state (step S _23), unwinding and winding pauses in the signal from the length measuring machine 12 when the wire feed length reaches the specified value (step S ₂₄ , S ₂₅ ), the cutting machine 11 operates and the electric wire 5
Is cut (step S ₂₆ ), only winding is restarted (step S ₂₇ ), and the detector 44 g detects that the rear end of the electric wire 5 has reached the position of the outlet end face processing device 13 (step S ₂₈ ).
Then, the winding is temporarily stopped (step S ₂₉ ), the output end face processing device 13 is operated, the rear end face of the electric wire 5 is sealed, and the winding is restarted (steps S ₃₀ and S ₃₁ ). Subsequently, the detector 44h detects that the rear end surface of the electric wire 5 has reached the position of the outlet band hooking device 15 (step 32), pauses (step _S33 ), and then performs rear end processing (step S33). ₃₄ ). The tail-processing is a processing corresponding to the tip processing in step S _22, specifically, binding of the binding bands 34 by the exit-side strapping device 15, accompanied by the take-up drum stand subsequent winding resumption The detection of the rear end face of the electric wire 5 by the detector 44 at a position above 2, the lateral movement of the winding drum stand 2 on the electric wire 5 side after that, and the binding band by the band fixing device 39 accompanying the lateral movement. 34 fixing process (see FIG. 8). After such processing is completed, the take-up side drum 4 is unloaded from the winding side drum stand 2 (step S _35).

On the other hand, the unwinding-side electric wire 5 remaining on the line
The detector 4 detects that the supply-side drum stand 1 is rewound after a predetermined time has elapsed (steps S ₃₆ and S ₃₇ ), and the tip of the cut wire has reached the position of the inlet-side end surface processing device 9.
When 4d is detected, the end of the electric wire 5 is temporarily stopped and the end surface of the electric wire 5 is sealed (steps S ₃₈ , S ₃₉ , S ₄₀ ), and if it is necessary to rewind the same electric wire in this state, The remaining amount of the electric wire is checked (step S ₄₁ ), and when there is a remaining amount (step S ₄₂ ), wait for the winding side drum 4 to be mounted on the winding side drum stand 2 again from this state, The rewinding operation similar to the above is repeated.

On the other hand, under the condition that the end surface of the electric wire 5 on the supply side is hermetically sealed, if the same electric wire 5 does not need to be rewound, rewinding is restarted again (step S ₄₃ ), and the incoming side band hanging device is provided. The detector 23c detects that the position 7 has been reached (step _S44 ), pauses (step _S45 ), and in this state the leading edge process (step _S46 ) is performed. The tip processing, the tip processing and the processing of substantially the same content of the step S _22,
The difference is that this process is mainly performed on the entrance side by using the entrance side band hanging device 7 or the like. Specifically, after the binding band 34 is bound to the tip portion of the electric wire 5 by the entrance side band hanging device 7, it is further rewound, and the rewinding is stopped in accordance with the detection of the end portion of the electric wire 5 by the detector 44b. The supply side drum stand 1 is laterally aligned and the band fixing device 39 fixes the binding band 34 to the inner surface of the flange portion 4a. Then, remove the unwinding side drum 4 from the drum stand 2 (step S _47).

By the operation of such a device, in the rewinding work of the electric wire, the manual work for the end surface treatment, the front end or the rear end treatment of the electric wire 5 which has been conventionally required is all performed automatically mechanically and continuously. It can be done by operation.

In the above embodiment, one end surface treatment device is provided on each of the inlet side (9) and the outlet side (13), but this can be achieved by adding a mechanism capable of reversing 180 °. good.

[0036]

As described above, according to the present invention,
In the rewinding process of electric wires, the manual work for sealing the end face of the electric wire, fixing the winding start end and winding end end to the drum, which was indispensable in the past, was eliminated, and the mechanization and automation effects were achieved. It was played, and it is extremely useful in industry.
