Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of transporting and loading a tire pallet and an apparatus therefor, and more specifically, to unloading a finished tire placed on a pallet at a tire unloading position and then emptying the empty pallet. After transporting to the pallet loading device and sequentially loading and loading a predetermined number of stages,
The present invention relates to a method of transporting and loading a tire pallet which is taken out and collected by a transfer device, and an apparatus thereof.

[0002]

2. Description of the Related Art Conventionally, finished tires of various sizes placed on a pallet stocked at a stock location are conveyed to an unloading position, and the finished tires are unloaded from the pallet at the unloading position and loaded on a truck or the like. In this case, a plurality of pallets on which the finished tires are placed are piled up and transferred to a carry-out position by a forklift or the like, where an operator unloads the finished tires from the pallets and loads them on a truck or the like.

After the completion of loading the finished tires,
The empty pallets had to be transported to the prescribed position again by a forklift. However, since the transfer of pallets loaded with finished tires and the transfer of empty pallets were all performed by forklifts, workability and work efficiency were extremely poor,
In addition, the loading and unloading of finished tires from pallets and the loading of trucks, etc., are all performed manually, and in the loading of trucks, there are many types of loading ports depending on the destination, and the frontage is narrow, so work efficiency is improved. Is extremely bad,
There was a problem that productivity was bad.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised by focusing on such a conventional problem, and uses a pallet having finished tires mounted thereon from a tire stock position to a tire unloading position using a forklift or the like. Anyone can easily transfer, unloading finished tires from pallets, and empty pallets can be automatically loaded to facilitate pallet collection work. It is an object of the present invention to provide a method of transporting and loading tire pallets and a device therefor capable of significantly improving productivity and workability.

[0005]

In order to achieve the above object, the present invention transfers a pallet on which completed tires are mounted and transfers a tire unloading position and an empty pallet to a pallet loading device. And a pallet loading device in which the transport direction and the carry-in port of the transport conveyor are installed in series, and the pallet loading device is in series with the transport conveyor at the bottom of a framed frame and has substantially the same plane. A guide conveyor arranged above and a pallet positioning means are arranged, and an empty space which is moved up and down along the frame on the guide conveyor and the pallet positioning means via the elevating means and is carried onto the guide conveyor. The gist of the present invention is to provide an empty pallet holding member for detachably holding the pallet.

The present invention is constructed as described above, and the pallet on which the completed tires are placed is conveyed from the tire stock position to the tire unloading position by the conveyor, and the tire is unloaded from the pallet at the tire unloading position. After that, the empty pallets are conveyed to the pallet loading device, the empty pallets are sequentially loaded, and after a predetermined number of empty pallets are loaded, the loaded empty pallets are taken out from the pallet loading device via the transfer device. Since it is transferred to the pallet collection position, it is possible to easily perform the work of transporting the pallet on which the finished tires are placed and the work of unloading the finished tires, and it is possible to improve the work efficiency. Stacking and collection work can be performed automatically and efficiently without human intervention.

Turns 90 ° when loading the held empty pallet 1a onto the loaded empty pallet 1a, and in this state, it descends to the lower limit position, and both sides of the empty pallet 1a located at the bottom stage. Hold the bottom surface.

When the holding claws 13a of the empty pallet holding member 12 have completed holding the lowermost empty pallets 1a, the plurality of stacked empty pallets 1a are lifted up to a predetermined position by the elevating means 11 and guided at this position. Conveyor 9
Wait until the next empty pallet 1a is loaded. Such an operation is repeatedly performed, and after the empty pallets 1a are stacked by a predetermined number of stages, the stacked empty pallets are taken out from the frame 7 of the pallet loading device 4 via a transfer device such as a forklift and are not shown. It transfers to the pallet collection position.

By carrying and loading the tire pallet by the above-mentioned method, the carrying work of the pallet 1 on which the completed tire W is placed and the unloading work of the finished tire W can be easily carried out. At the same time, the work efficiency can be improved, and the stacking and recovery work of the empty pallets 1a can be performed automatically and efficiently without human intervention.

[0018]

According to the present invention, the pallet on which the tires completed as described above are placed is conveyed from the tire stock position to the tire unloading position by the conveyor, and the tire is unloaded from the pallet at the tire unloading position. After that, the empty pallets are conveyed to the pallet loading device, the empty pallets are sequentially loaded, and after the empty pallets are loaded by a predetermined number of stages,
This stack of empty pallets is taken out from the pallet loading device via the transfer device and transferred to the pallet collection position, so a pallet with finished tires is used from the tire stock position to the tire unloading position using a forklift, etc. Anyone can easily transfer, unloading finished tires from pallets, and empty pallets can be automatically loaded to facilitate pallet collection work. As a result, there is an effect that productivity and workability can be significantly improved.
