[0003] As shown in the basic configuration diagram of FIG. 10, these pallet racks include a transport vehicle 102 having rotatable wheels 103 on the lower surface, and a wheel 10 of the transport vehicle 102.
3 is configured by a guide rail 104 on which the roller 3 rolls and travels, a drive vehicle 105 capable of traveling the transport vehicle 102, and the like. The transport vehicle 102 has a pallet hook 107 that can be engaged with a pallet P mounted on a number of free rollers 106 provided on a vertically long pallet rack 101. 108, a high position rail surface 109 and a pair of inclined rail surfaces 110
a, 110b are formed. In addition, the driving bogie 105
Is connected to one end of a wire 111.
Is connected to the carrier 102 via a pulley 112.

A pallet P on which the article W is placed
Are sequentially placed on the free rollers 106, conveyed to the rear side of the pallet rack 101, and stored. When removing the pallet P from the pallet rack 101, for example, the driving bogie 105 is pushed rearward (in the direction of arrow B in FIG. 10) with a fork F of a forklift, and the transporting vehicle 102 is driven forward (in the direction of arrow C in FIG. 10). Then, the wheel 103 is moved from the low position rail surface 108 of the guide rail 104 to the high position rail surface 109 via the inclined rail surface 110b. Due to the movement of the wheel 103 to the high rail surface 109, the pallet hook 107 protrudes above the transport surface H of the free roller 106 as shown by a two-dot chain line in FIG. The pallet P is locked.

[0005] In this state, the driving bogie 105 is moved to the fork F

02 travels further forward, the pallet P locked by the pallet hook 107 is transported to the article entrance / exit portion at the front end of the free roller 106, and the pallet P is taken out of the pallet rack 101 by the fork F.

[0006]

However, in the pallet rack 101, the wheels 103 of the carriage 102 have lower rail surfaces 108, higher rail surfaces 109, inclined rail surfaces 110a, 11
0b, it is easy for foreign substances such as dirt, dust, and oil to adhere and accumulate on the guide rail 104, making it difficult for the transport carriage 102 to travel smoothly, and Pallet rack 101
However, there is a problem that it is difficult to smoothly store and take out the sheet.

That is, foreign matter easily adheres to the guide rail 104, particularly on the low-level rail surface 108 at the depressed position, and when the wheel 103 of the transport vehicle 102 rolls due to the foreign material, the transport vehicle 102 is moved In some cases, noise may be generated due to the vibration, and depending on the size of the foreign matter, the wheels 103 may not be able to roll, and the carrier 102 may stop. Also, depending on the case, a large force may be applied when the transport vehicle 102 starts running due to the pallet hook 107 of the transport vehicle 102 not falling from the transport surface H of the free roller 106 or the foreign material being caught between the wheel 103 and the guide rail 104. For example, it becomes difficult to smoothly move the transport cart 102 because it becomes necessary.

Particularly, a wooden pallet P is used as the pallet P.
When the pallet P is used repeatedly, the wood pieces are apt to be cleaved by the repetitive use, and fragments thereof may accumulate on the guide rails 104, or foreign matter or the like may fall off the articles W placed on the pallet P, and the guide rails may be used. The pallet 104 may accumulate on the pallet 104, which makes it more difficult for the transport carriage 102 to travel smoothly, and makes it difficult to smoothly move the pallet P (article W) into and out of the pallet rack 101.

In order to solve such a problem and to make the transport carriage 102 run smoothly, guide rails 104 are provided.
Although it is conceivable to remove foreign matter and the like by cleaning each rail surface of the pallet rack, generally, since the length of this type of pallet rack 101 is relatively long and a plurality of rows are arranged in parallel, cleaning work is often performed. It is difficult for the pallet rack 101 to perform itself, and in order to allow the wheels 103 to travel smoothly, it is necessary to frequently remove foreign matters that have adhered and accumulated on the guide rails 104. There was a problem that it was easy to become.
