Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention conveys a long object such as a roll from a storage area,
The present invention relates to a long and long object transfer and swing device that transfers a long object to a transfer machine of a stacker crane in the warehouse when it is stored in the warehouse.

[Prior art]

There are various techniques for carrying and turning long products such as rolling rolls and carrying rolls, but the main one is carrying and turning one by one. The following four examples are implemented as this method.

A long object is hung on a turning device by a crane, etc., turned, and then lifted.

One or two long objects are placed on a conveyor chain conveyor, and the conveyor chain conveyor pushes or drops the material into a swivel device and swivels it, and then conveys it on the chain conveyor.

A trolley that conveys one or two long objects can be moved forward, backward, leftward, and rightward, and is conveyed and turned.

A trolley for transporting one or two long objects is rotated while being loaded on the trolley.

[Problems to be solved by the invention]

If either method is used, the work efficiency is poor. In the case of the transporting conveyor chain conveyor, there is a problem in that in the case of a heavy object, the chain conveyor needs to be strong, a large driving force is required, and a fragile object cannot be handled.

In the case of carrying a long object on a dolly like the one described above and the like, a large number of dollies are required and the equipment cost is high. Also,
As described above, a vehicle that travels forward, backward, leftward, and rightward takes a long time to perform a turning operation, resulting in poor work efficiency. Furthermore, it is necessary to separately provide means for adjusting the intervals between a plurality of long objects and aligning shaft ends. There is a problem.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device capable of efficiently performing interval adjustment, axial end alignment, swiveling, and transportation for storing a plurality of long objects in a storage rack of a warehouse in order to solve the above problems. And

[Means for solving problems]

The present invention has the above-mentioned object in a transport swivel device comprising a swivel carriage 1 and a transport carriage 2, in which the swivel carriage 1 is capable of self-propelled frame 121 and capable of horizontally swiveling on the self-propelled frame 121. And a revolving frame 15 is provided.
Is provided with a pair of support frames 16 and a boarding rail 13 for the carriage 2 between the support frames 16, and a long object can be loaded on the support frame 16 in the axial direction of the long object. A plurality of pairs of loading platforms 141 that are movable in parallel to the orthogonal direction and a means for moving the loading platforms are provided, and the carriage 2 is capable of receiving a long object and in the axial direction of the long object. A pedestal 221, which can be moved to, and means for moving the pedestal 221,
This is achieved by a conveying and turning device characterized in that an elevating frame 23 on which the pedestal 221 is placed and which can be moved up and down, and elevating means 24 of the elevating frame 23 are provided.

[Action]

Since the transport carriage has a pair of pedestals that can move in the axial direction of the long object on the elevating frame, it is possible to elevate the elevating frame of a long object (for example, a roll) on a stand. It can be received by and can be boarded on the revolving frame with the long object being lifted. Further, when it is not possible to place the long object on the loading platform on the support frame because the axial ends are not aligned, the receiving platform can be moved in the axial direction to align the axial ends.

The swivel carriage can move one of the two pairs of loading platforms in the direction orthogonal to the axial direction of the long object, and the spacing between the loading platforms can be adjusted. Even when the distance is different from the distance between the roll cradle of the transfer machine, the transfer from the swivel carriage to the transfer machine or the transfer from the swivel carriage to the transfer carriage can be performed without any trouble.

Since the swivel vehicle has means for swiveling the loading platform,
It is possible to change the mounting direction of the long object on the mounting table to the mounting direction of the transfer machine (or to the mounting direction of the storage rack of the warehouse).
