Description

Pulling apparatus having wire separation preventive measure

The present invention relates to a pulling device having a wire separation prevention means, and more specifically, a wire separation prevention means that guides the cable to be easily unwound from a rotating drum during wire pulling (unbinding) work without being tangled or falling to the outside. It relates to a pooling device having.

Generally, factories that produce wires and cables produce and sell wires and communication cables in bundled rolls or drums, and at sites where cables are used, work is carried out by unwinding the cables from rolls or drums. .

However, when cables are unwound from rolls or drums in the field as described above, tangles of untangled wires often occur, and all processes have to be stopped to untangle the tangled wires, which reduces productivity and causes enormous losses. There was a problem.

In addition, when cables are tangled, the worker must manually untangle them, which causes the work to take a long time. Furthermore, there is a problem that workers must always be on standby to untangle cables in sites where automation is used.

In addition, in a field where cables are used, the process may progress slowly or the wires may be supplied slowly, and tangles like the above may be less likely to occur. However, if the process progresses quickly or cables must be supplied at a high speed, the cable tangle phenomenon may affect the work speed. Failure to keep up with the process often results in tangled problems.
