Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a belt-shaped material storage device that compactly stores a belt-shaped material being transported, such as a strip being processed in a steel factory, in a coiled form.

The strip storage device converts the intermittent transfer of the transferred strips into continuous transfer, continuous transfer into intermittent transfer, and furthermore continuous transfer into temporary stop, and converts from hot-rolled coil to cold-rolled steel strip,
In equipment that manufactures tinplate, galvanized iron, and other products, on the entry and exit sides of pickling equipment, cold rolling equipment, cleaning equipment, surface treatment equipment such as plating, etc., and on the entry side of ERW pipe equipment, respectively. Traditionally used.

Conventionally used strip storage devices include a plurality of sets of fixed guide rolls and lifting guide rolls, and the strips are passed alternately between the fixed guide rolls and the lifting guide rolls. raise and lower within the required range,
A loop tower type strip storage device adapted to absorb the difference in speed between intermittent processing and continuous processing, or a fixed guide roll and a guide roll disposed on a trolley,
There is a loop car type strip storage device in which the cart is made to travel within a predetermined range using a travel drive device, and the difference in speed between intermittent processing and continuous processing is absorbed between a fixed guide roll and a guide roll on the cart. .

However, these conventional devices are inconvenient both economically and in terms of handling because the scale of the devices has increased as equipment speeds have increased and mass production has increased.

Further, as conventional band-like object storage devices, there are circular-type band-like object storage devices as shown in FIG.

) is pushed and supplied from the outside to the inside of the outer roller cage 6z), stored inside the outer roller cage (α) and outside the inner roller cage (d), and is also supplied from the outside to the inside of the inner roller cage (d). It is pulled out and sent outside.

In addition, in Fig. 2 (a) and (b), (1) is an outer roller cage (fL) formed by arranging a plurality of horizontal rollers in a circular shape centered on the horizontal axis (fL). is an outer roller cage (formed by arranging a plurality of horizontal free rollers (o) concentrically with U in a circular shape, γ is an inner roller cage, shi) is a diagonal roller for direction change, (q)

The strip is drawn out and pulled out by a strip drawing roller (r).

However, in the above-mentioned circular type storage devices, 1) the strip feeder 8) is pushed in and stored, so they can be applied to thick plates such as hot-rolled strips, but they are not suitable for cold-rolled strips. ) A thin plate like an IJ tube cannot be pushed in and is inappropriate. 11) In both cases, the strip supply position and discharge position are not on the same line, and there is a height deviation H1 and a deviation L on the plane, so the strip cannot be processed. The center line of the main equipment (e.g. pickling line) and the storage device will be misaligned, complicating the arrangement of the equipment, iii] Figure 1 (A)
), the width direction of the strip IJ tube (s) is vertical and the strip is transferred on the roller, so the strip width end that comes in contact with the roller is damaged, and the strip is transported horizontally on the strip supply side.
A vertical conversion device (j) is required to make the IJ knob vertical.
There were various drawbacks, such as the need for leveling conversion R(k) to make the vertical strip horizontal on the strip discharge side, the structure becoming complicated, and the space being taken up.
