Description

A storage and discharge apparatus of strips

The present invention relates to a storage and discharge device of the strip, and more particularly to a storage and discharge device of the strip that can be stored at the same time while discharging the strip supplied from the uncoiler to the tube.

In general, when the strip is supplied from the uncoiler with the strip wound to the pipe making machine or the continuous roll forming apparatus that manufactures the steel, etc., the supply is to be performed continuously so that work is not temporarily stopped.

In other words, when the strip is continuously fed using an uncoiler, the winding amount of the strip is limited. Therefore, a new unit is added again after about 10 to 20 minutes until one unit is exhausted. It will take time and manpower as the tube is stopped every time the unit is replaced in order to resupply it to the tube. It will not only take time and manpower. There is a problem that occurs.

Therefore, in order to continuously supply the strip without stopping the operation of the tube, the end of the strip wound and supplied to the uncoiler and the first part of the newly supplied strip are welded so that the strip is continuously supplied to a facility such as a tube. An apparatus for doing this has been proposed.

Conventionally, a device for supplying a strip as described above has disclosed a rotary looper of Korean Patent Registration No. 313474.

As shown in FIG. 1, a fixed drum 11 is mounted at the center of the base 10, and an inner winding roller group 12 is installed at an outer edge of the fixed drum 11. A spiral guide roller group 13 is provided inside the roller group 12 so as to protrude forward.

The outer side of the fixed drum 11 is provided with a rotating drum 14 is rotated in accordance with the operation of a separate drive means, the guide drum 15 is rotatably installed on one side of the rotating drum (14).

An inner guide roller group 16 is provided on the inner edge of the rotating drum 14 in a concentric manner, and an outer winding roller group 17 is installed on the outer edge of the rotary drum 14, and the outer base ( On the 10), the outer guide roller group 18 is provided concentrically.

One side of the base 10 is configured to guide the guide drum 15 through the pinch roller R and the plurality of induction roller groups 19 wound around the uncoiler C. The strip (S) passing through the guide roller group 13 is configured to be discharged and supplied to the tube pipe (P).

Accordingly, the guide coil 15 after the strip S wound around the uncoiler C is guided through the guide roller group 19 and drawn between the outside coil roller group 17 and the outer guide roller group 18. ) And the advancing direction is reversed and drawn between the inner winding roller group 12 and the inner guide roller group 16, and then wound around the spiral guide roller group 13 to be supplied to the tube tube P repeatedly. In the execution of the strip (S) is to be made.

At this time, when the strip S is exhausted from one unit bundle, the rotating drum 14 is rotated counterclockwise by the operation of the driving means, so that the strip S wound on the uncoiler C is rapidly rotated. The strip S is stored in the outer winding roller group 17 and the inner winding roller group 12 while being discharged through the spiral guide roller group 13.

Subsequently, when all the strips S wound on the uncoiler C are exhausted, the driving means rotates in reverse to rotate the rotary drum 14 clockwise so that the inner winding roller group corresponds to the supply speed to the pipe tube P side. Unwinding the strip (S) wound on the inside (12) and at the same time the storage portion wound on the outer winding roller group 17 is guided by the guide drum (15) and transferred to the inner winding roller group (12) continuously Supply to the tube (P) side is made.

Then, while the pre-stored strip S is released and supplied to the rotary drum 14, a unit bundle of a new strip S is mounted on the uncoiler C, and then the tip of the strip S is pinched. It is to be welded with the end of the first strip (S) exposed immediately before the) and to wait in a state that the strip (S) can be continuously supplied.

However, such a conventional technique is severely deformed in the wound state, such as the sliding of the strip stored in the inner and outer winding roller to the side, and when the width of the strip is different, it affects the storage state. Although it is not provided, the guide roller group is fixedly installed in a concentric circle at a predetermined interval on the outside of the outer winding roller group and the inner winding roller group, but it is difficult to effectively prevent the stored strip from being loosened by the load, and drawn into the apparatus. Several problems have been inherent, such as the difficulty of effectively controlling the speed of the strip being discharged or discharged.

An object of the present invention for solving the above problems is to provide a storage and discharging device of the strip to prevent the stored strip is relaxed in the central axis direction or deformed in the radial direction to achieve a very stable operation.

Another object of the present invention is to provide a storage and discharging device for a strip which is very easy to control the speed of the inlet side of the uncoiler.
