[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for pre-feeding coiled sheet materials to be installed in an electric resistance welded pipe manufacturing line, a thin sheet feeding apparatus for a punching machine, and the like.

[0002]

2. Description of the Related Art FIG. 5 is a diagram illustrating the configuration and functions of a conventional coil material replenishing section and a feeding and feeding section provided in an electric resistance welded pipe manufacturing apparatus.

[0003] As shown in the figure, a coil replenishing and feeding supply device for producing an electric resistance welded tube includes an uncoiler section 34 for rotating a coil 4b mounted on an uncoiler mandrel 32 in a feeding direction and transferring the coil 4b to a downstream side. Opener arm 1 for peeling off the feeding section from the production line
8. Pinch rolls 13a, 13b for gripping the rolled-out coil from above and below and rotating and transferring the same, and a coil car 35 for transferring the next new coil 4b to the uncoiler mandrel 32. In the figure, reference numeral 15 denotes an uncoiler leveler for correcting the curving of the plate material to be fed.

The uncoiler mandrel 32 is constructed so that it can be reduced and expanded in the direction perpendicular to the axis. After the coil is inserted in the reduced state, it is expanded so that the shaft hole of the coil can be pushed out from the inside and fixed. It is configured.

Next, the function of the apparatus having the above configuration (coil replenishing operation) will be described. First, the uncoiler section 34
After the leading coil 4a, which has been sequentially fed out toward the production line, is completely supplied by the rotation of the uncoiler mandrel 32, the next mandrel 32 which has been emptied on the coil car 35 with respect to the empty mandrel 32 The new coil 4b is inserted and fixed.

Next, after the new coil 4b is mounted, the tip is peeled off by the opener arm 18 and transferred downstream to be gripped by the pinch rolls 13a and 13b. I do.

With this arrangement, the rear end of the preceding coil 4a and the front end of the next coil 4b which follow the rear end of the preceding coil 4a fixed (stop running) by the shear welder 36 installed downstream of the uncoiler level 15 have a predetermined shape. And then welded.

By the operation, the leading coil 4a and the new coil 4
b are connected to each other and supplied to the processing device in a continuous state. Thereafter, by repeating the same operation, it becomes possible to manufacture a continuous ERW pipe.

A looper 33 is provided downstream of the shear welder 36 as a means for ensuring a supply amount during the rear end stop (the preparatory work) time of the leading coil 4a.

The conventional coil supply section is constructed as described above. After the preceding coil 4a mounted on the uncoiler mandrel is completely lost, the mouth of the next new coil 4b is opened to the pinch roll 13. It takes time to pull out and further transfer and connect to the rear end of the preceding coil 4a,
The longer the time until the connection is, the longer the looper 33 needs to be stored.

Had been taken.

[0012] Therefore, a long time is required for replenishing a new coil because the leading end feeding operation is performed by the uncoiler. In a device for continuous production such as an electric resistance welded pipe manufacturing line, the leading end of the next material after the rear end of the preceding material is stopped. It is necessary to lengthen the means (looper) for stocking the coils to be consumed until they arrive and connect the rear end of the preceding material and restart.

However, in a factory or the like where the installation space of the looper 33 is limited, a necessary stock amount cannot be obtained, so that continuous production becomes impossible, which may be what is called batch production. As a result, the operation rate of the entire apparatus is reduced, and the productivity is significantly reduced.

The present invention solves these disadvantages and provides a simple
Although it is a simple configuration, it is possible to shorten the replenishment period of the new coil performed with the consumption of the leading coil , and
