Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport vehicle elevator for raising and lowering a transport vehicle from one floor to another.

In such an elevator, there is a gap between the edge of the cage side floor wall on the entrance/exit side and the edge of the fixed side floor wall on the elevator entrance/exit side to prevent collision between the cage and the fixed side floor wall. will be suppressed. Incidentally, although it is common practice to provide guiding rails in elevators, it is still common practice to provide the above-mentioned gap.

As a result, when getting on and off the carrier with respect to the cage, the contact parts of the wheels of the carrier fall into the gap, making it difficult to move the carrier smoothly. . And, in particular, controlled to run automatically,
In the case of a so-called unmanned transport vehicle, if the transport vehicle unexpectedly stops due to the above-mentioned gap, trouble may arise in which the travel control cannot be performed as specified.

Therefore, in the past, as shown in FIG. A fluid pressure cylinder O2 for pushing and pulling the section 4m' (30) is provided to move the forming member (column) toward the fixed side floor wall section when getting on and off the IR vehicle. There is.

According to the above-mentioned conventional means, since the entire transport vehicle (a) is loaded, it not only has the disadvantage of resulting in a large loss and an expensive structure, but also has the disadvantage that the cage side floor wall forming member 0) is used for loading the cargo. It must be supported so that the cage side floor wall forming member (30) can be pushed and pulled with a hydraulic cylinder (3). In addition, a structure for supporting the cage IJ floor wall forming member (30) is required because a large push/pull operation force is required to perform push/pull operations accurately even when a loaded transport vehicle (Al is loaded); Moreover, the structure of the mechanism for pushing and pulling the cage side floor wall forming member (30) is also complicated and expensive, leaving room for improvement.

The present invention has been made in view of the above-mentioned circumstances, and its object is to provide an elevator for a transport vehicle that has a simple structure and can smoothly move a transport vehicle regardless of the gap. At the point.

The characteristic configuration of the elevator for a transport vehicle according to the present invention is that the running path forming member that fills the gap between the edge of the cage side floor wall on the entrance/exit side and the edge of the fixed side floor wall on the elevator entrance/exit side is provided with the traveling path forming member as described above. The cage is provided with a function that can be freely switched between an operating position in which it enters the gap and a storage position in which it is retracted below the cage-side floor wall, and its effects are as follows.

That is, when raising and lowering the cage, by switching the traveling path forming member to the retracted position below the cage side floor wall, collision of the traveling path forming member with the fixed side floor wall can be prevented. Although I tried to make him depressed,
When the transport vehicle is loaded onto or exited from the cage, the travel path forming member is switched to the operating position where it enters the gap to fill the gap, thereby allowing the transport vehicle to move smoothly regardless of the gap.

Therefore, it is possible to have a small and simple structure in which a small traveling path J forming member is provided to fill the gap and can be switched freely. Since only a portion of the weight of the transport vehicle acts on the road forming member, the structure for holding the running road forming member in the operating position can be simplified, and furthermore, the structure for holding the running road forming member in the operating position can be simplified. Since the weight of the transport vehicle does not act when switching the members, the structure for switching the traveling path forming members can be simplified, which is advantageous in terms of overall production. With this configuration, it is now possible to get on and off the transport vehicle smoothly.

Embodiments of the present invention will be described below based on the drawings.
