Abstract

PURPOSE:To enable a strip coil storing facility as referred to the titled to be simplyfied with the floor space utilization efficiency augmented by arranging both a rail with a coil storing stand to the longitudinal direction and a rail to the transversal direction which is used for receiving and shipping in such a way that a car with a coil lifting and supporting device can travel on both the rails. CONSTITUTION:A coil S which has been placed on a coil delivery stand 7a is transversally moved on a rail 2 which is installed transversally by means of a working beam 8 while it is supported by a car 6, then is transferred to a receiving stand 7b in the specified row. Subsequently, a car 5 goes in under the coil receiving stand 7b, where the coil is received while it is lifted up by a coil lifting and supporting device (not shown), then the coil is moved to a specified stand 4 on the rail 1 which is longitudinally installed, and is finally transferred to the specified stand 4. In the case that the coil is shipped out, the operation concerned is similarly effected by using the car 5, the rail to the transversal direction, and another car 6. This configuration enables the structure of the facility to be simplyfied, and both the floor space utilization efficiency and the working efficiency to be augmented while the crane is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a strip coil storage facility in a steel mill, and more particularly to a storage facility whose general access can be automated.

Conventional Technology In conventional strip coil storage equipment, the coils were lifted and moved by inserting tongs suspended from a large overhead crane into the center hole of the coil from both sides. , It is necessary to maintain sufficient space in the front, back, left and right to allow for shaking when inserting and removing the tongs and lifting and lowering. Also, the building needs to be tall and strong to install the crane, and maintenance of the crane is also troublesome. Moreover, there were drawbacks such as the difficulty of automating a single squeezer.

Problems to be Solved by the Invention The present invention eliminates the overhead crane and attempts to move the strip coil in and out of the coil holder for 1M using a traveling cart, since the above-mentioned drawbacks of the conventional method are caused by the use of an overhead crane. It is.

Means for Solving the Problems The present invention provides vertical rails arranged in parallel, a large number of coil mounting stands arranged parallel to the rails at high places on both sides of the rails, and coil loading/unloading stands orthogonal to the rails. A coil delivery stand installed in the horizontal rail in vertical alignment with the coil placing stand, and a trolley frame of the trolley running on the vertical rail. A traveling trolley equipped with a coil cradle, a traversing frame guided and supported so as to be movable in the lateral direction directly below the coil cradle, and a coil lifting/lowering support device provided on the traversing frame, and a lateral rail. It has a transverse trolley that runs and is equipped with a coil lifting/lowering support device, and the coil lifting/lowering supporting device enters into a gap that opens vertically in the center of each of the coil placing stand, coil cradle, and coil delivery stand, and is connected to each of the above-mentioned stands. It is characterized by the transfer of strip coils.

In order to store working strip coils (hereinafter simply referred to as coils), the coils are supported high on the coil lifting support device of the traversing cart, and the coils are moved traversely, and placed above the coil transfer table which is aligned with the desired coil placement table to be stored. Position the coil and stop.

The cradle on which the coil lifting support device on the traversing truck supports the coil is configured to be sufficiently long in the traversing direction so that the coil will not fall when the truck starts or stops.

After the above-mentioned stop, the coil lifting/lowering support device descends to transfer the coil onto the coil delivery table, and then the traversing truck returns to its original position.

Next, the traveling cart comes to the position of the carrying-in traversing rail and stops, and the traversing frame moves laterally to move the coil lifting/lowering support device directly below the coil delivery table that supports the coil. Next, the coil lifting and lowering support device rises to receive the coil on the coil delivery table.

At this time, the coil lifting support device is usually located outside the vertical rail, and the weight of the coil may cause the traveling truck to fall. Therefore, outriggers are installed on the truck frame to prevent the truck from tipping over, and the coil lifting support device The outriggers are used to position the traveling trolley so that it is directly below the center axis of the coil.

Next, the traversing frame returns to the center position of the truck frame and moves the coil above the coil cradle, and then the coil lifting/lowering support device descends to transfer the coil onto the coil cradle.

Next, the traveling truck moves with the outriggers stored, and stops at the side of a desired coil placement stand where the coil is to be stored. Then, the coil is transferred from the coil holder onto the coil placement table by an operation opposite to the above-described coil transfer operation.

When carrying out the coil on the coil placement stand, the above-mentioned operation may be reversed. That is, the coil is transferred onto the coil holder of the traveling truck and carried to the intersection with the lateral force direction rail for carrying out, where the coil is transferred onto the coil delivery table and the traveling truck returns to its original position. Next, a traversing truck comes, supports the coil on the coil lifting and lowering support device of the traversing truck, and carries it out.

Since the traversing frame of a traveling trolley can traverse below the coil placement stand, by providing outriggers, it is possible to stably transfer the coil even if the vertical rail width is approximately the same as the coil width. It is not necessary to provide a gap between the coils for coil movement.

Embodiment FIG. 1 shows the layout of a strip coil storage facility according to the present invention. Horizontal rails 2 and 3 are provided at both ends of the vertical rails 1 which are arranged in parallel at intervals, and the strip coils S are supported on both sides of each vertical rail 1 with their center holes facing in the horizontal direction.

A traveling trolley 5 for transporting the coil S onto the coil placement table 4 runs on the vertical rail 1, and a transverse trolley 6 for loading and unloading coils runs on the horizontal rails 2.3, respectively.
Inside the rails 2 and 3, a coil delivery stand 7 is provided which is vertically aligned with the coil placement stand 4.

When the coil S is placed on the coil transfer table 7a at the end of the rail 2 by the working beam 8, the cart 6 comes directly below the coil S, lifts it up and supports it, and then moves across to place it in the desired row. The coil is placed on the coil delivery table 7b. Next, the trolley 5 receives the coil S from the coil delivery table 7b, moves it laterally directly above the rail 1, travels on the rail 1, and transfers it onto a desired coil placement table 4.

During the traverse, the lower surface of the traverse frame 17 is supported by the roller 15 at the front of the traverse and the roller 6 at the center, and the upper side is guided by the restraining rollers 23 at the front and center of the traverse, and the coil elevating support device 30 moves the coil S. It counters the overturning moment applied to the transverse frame 17 when supported.

When the traversing frame 17 supports the coil S on the coil elevating support device 30 and traverses to the position of the center line a, outriggers are attached to brackets 34 protruding from the front and rear sides of the truck frame 11 so that the traveling truck 5 does not fall. - A hydraulic jack 35 for use is fixed, and a conical cup 36 fixed to the ram engages with a positioning stand 37 attached to the floor for each coil placement stand 4 when the jack is operated, thereby positioning the truck frame 11. It is constructed so that it can be stably supported.

Note that the positioning function of the jack 35 only needs to be performed on one side of the rail 1. The hydraulic cylinders 31 and 35 are controlled by a hydraulic pressure generating device built into the traveling carriage 5.
