Description

Device for preventing coil telescope of coiler

The present invention relates to a winding machine for winding a strip into a coil, and more particularly, to a coil telescope preventing device of a winding machine in which the strip is wound uniformly by eliminating the telescope phenomenon in which the strip is ragged.

In general, a winder is a device that rolls a coil through a cold rolled or hot rolling mill for convenience of storage, transportation, and other processing before sending it to a post process.

Such a winder, as shown in Figure 3, is installed on the side of the housing 50 of the winder, the mandrel 51 to which the strip 100 is wound, and the strip 100 wound to the mandrel 51 It consists of a hold roll 52 for pressing and supporting, a cutter 60 for cutting the strip 100 and a guide roll 70 for guiding the strip 100 are installed at the front of the winder. The lower part of the reel 51 has a structure in which the coil car 80 for conveying the wound coil 90 is put.

Therefore, the strip passing through the rolling mill is wound on the mandrel through the cutter and the guide roll. When the wound coil reaches the desired diameter, the strip is cut by the cutter and the end of the cut strip is completely wound on the mandrel. When the diameter of the mandrel is reduced, the coil car will remove the coil from the mandrel and transfer it to the post-process.

However, the conventional winding machine has a problem in that a telescope phenomenon in which the strip is not wound properly but is rolled up in a jagged fashion after the strip is cut by the cutter cannot support the tip of the strip.

That is, a strip length of about 1-2 turns is usually placed in the coil from the strip cutter to the mandrel. As the tip of the strip is continuously wound on the mandrel with an unsupported sieve, as shown in FIG. 4, Telescope is going to happen.

Particularly, when the strip is out of the guide roll, the strip scope is not controlled at all and is only pressed by the hold roll to be supported.

As the telescope is generated, problems such as damage to the telescope portion of the coil or scratches due to friction during the transfer or bending of the coil, damage to the facility due to the breakage of the band that binds the coil, and an accident of worker safety are caused. This occurred.

Therefore, in order to calibrate such a telescope, various operations such as mandrel adjustment or impact on the side of the coil have been performed in the past, but the work was not smooth and the performance was not sufficient. This is a wasteful problem.

Accordingly, the present invention has been made to solve the above problems, by ensuring that both sides of the strip wound on the mandrel is guided and wound accurately by the guide roll, it is possible to safely and easily correct the telescope generated in the coil outer diameter It is an object of the present invention to provide a coil telescope prevention device of a winding machine.
