2. Description of the Related Art Transport trolleys for transporting rolling coils are used at entrances and exits of storage yards, such as at a rolling coil yard in a steel mill. FIG. 9 shows an example of the transport trolley device provided at the entrance of the storage yard. In FIG.
A transport trolley device 2 is arranged along the wide entrance of the storage yard 1 for the rolled coils, and a roll conveyor 8 is transported to the transport trolley device 2 by a transport conveyor 3 from rolling equipment or the like. The rolling coil 8 is transferred by the transfer machine 4 between the transfer conveyor 3 and the transfer trolley device 2.

When the rolling coil 8 is frequently loaded and unloaded into and out of the storage yard 1, in order to increase the loading and unloading efficiency of the rolling coil 8, the transport trolley device 2 is connected to the storage yard 1 so as to face the entrance of the storage yard 1. Double-row parallel bogie track 5 with two rails
Is provided. A bogie traversing device 6 is disposed orthogonally to both ends of the double-row bogie traveling track 5, and a large number of self-propelled coil carrier bogies 7 are provided on the bogie traveling track 5 so as to be able to circulate as indicated by arrows. I have. The rolled coil 8 is placed and transported on the coil transport trolley 7, and the rolled coil 8 is transferred from the coil transport trolley 7 to the storage yard 1 by a plurality of transfer machines (not shown) on the storage yard 1 side in front of the storage yard 1. To a large area continuously.

FIG. 10 shows a conventional example of a trolley traversing device 6 used for the transport trolley device 2. 11 is a view taken along line XI-XI in FIG. 10, and FIG. 12 is a view taken along XII-XII in FIG.
A line arrow is shown.

As shown in FIGS. 10 to 12, the bogie traversing device 6 forms a low-level traversing base 6a on a part of the base 5a of the trolley running track 5, and the traversing base 6a is provided at a wide interval on the traversing base 6a. A pair of traversing rails 51 is provided. A moving platform 53 is provided on the traversing rail 51 so as to be able to traverse via wheels 52, a traversing cylinder 54 is connected to the moving platform 53, and a bogie traveling track portion 55 that matches each bogie traveling track 5 on the movable platform 53. Is provided.

[0006] After the coil carrier 7 on one carriage traveling track 5 is loaded on the carriage traveling track portion 55 on the moving platform 53 and stopped, the moving platform 53 is driven by driving the traversing cylinder 54. The traverse moves to the position of the other truck traveling track 5.

However, in the conventional transport trolley device, the object to be traversed by the traversing device is a large weight including the trolley traveling track portion 55 and the movable gantry 53. The equipment becomes large-scale to reciprocate every stroke of the orbit 5 intervals every time,
Construction costs increase. In addition, a large driving force is required for the traverse shift of the coil carrier 7, resulting in poor energy efficiency and high running cost. Furthermore, since the heavy weight is shifted transversely, it takes time for the shift movement, and the coil carrier 7 cannot enter the movable platform 53 until the movable platform 53 returns to the original position. It is easy to become a bottleneck in performance.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a simplified configuration and a reduced size of a traversing device and a trolley traveling device, which can reduce construction and maintenance costs and increase operating efficiency. The purpose is to provide.

It is shifted horizontally by magnetic levitation movement.

At this time, the coil carrier traverses the divided portion of the trajectory of the trajectory caused by the laying of the traversing linear synchronous motor alternately with eight traveling wheels, and stops at a fixed position on the traverse device. Under this condition, the traversing guide rail as the second traveling lane is sent out to a position opposite to the front and rear of the truck, and the horizontal guide rollers before and after the coil carrier are guided in contact with the traversing guide rail, and By the driving of the synchronous motor, the vehicle is shifted laterally on the other bogie traveling track by magnetic levitation movement.

Positioning on the other truck traveling track, stopping the drive of the traversing linear synchronous motor, placing the coil carrier on the other truck traveling track, and moving the traversing guide rail to the retracted position. Then, the coil carrier can be magnetically levitated on the other truck traveling track, and at the same time, the subsequent coil carrier can be loaded on the truck traversing device on the original truck traveling track. That is, each time the traversing linear synchronous motor completes the traversing operation in one direction of the coil carrier, the next coil carrier can be received on the traversing device, and the traverse shift time cycle of the coil carrier is reduced. As a result, the operating efficiency of the coil carrier is improved, and the carrier capacity of the entire apparatus can be increased.

In addition, the coil carrier cart is driven by the linear synchronous motors of the cart traveling tracks in each row to travel while the coil carrier car is rolling on the traveling track by the wheels, and is linearly moved at a fixed position on the traversing device. By stopping the synchronous motor and subsequently driving the traversing linear synchronous motor, the coil carrier is traversed by magnetic levitation to a position on the other traveling road side.
