Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for entering and leaving a car and a method for operating a pallet in a mechanical parking lot.

[0002]

2. Description of the Related Art There are two types of mechanical parking lots: a pallet system in which a pallet is used to transport and store an automobile, and a palletless system in which an automobile is transported directly by a transport apparatus without using a pallet. Fig. 24 shows the procedure of the pallet-type loading / unloading operation.The loading vehicle is placed on the pallet in the loading cab, and the actual pallet is loaded into each storage layer by the loading elevator and bogie as shown by solid arrows. It is transported to a parking room and stored there. Also, as shown by the solid line arrow, the exiting vehicle is also transported from the parking room of each storage layer to the exit elevator room by the bogie and the exit elevator, and exits from there.

In this pallet system, an empty pallet after the exiting vehicle has to be recovered and supplied to the entry / exit room. For this reason, both the outgoing elevator and the incoming elevator have a two-stage frame structure, and an actual vehicle pallet (referred to as a pallet on which an automobile is mounted in this specification) is mounted on the upper frame.
To accommodate a plurality of empty pallets (referred to herein as pallets on which no car is mounted) in the lower frame, and has a space for storing empty pallets stacked below each elevator, The required number of pallets can be stored. The exit elevator has a stacking mechanism, and the entrance elevator has a step balancing mechanism. The empty pallet processing in the above pallet method is to store some empty pallets in the elevator for loading and unloading as shown by the dotted line arrow and pay it out at the same time as the transfer of the car. The pallet is used to pick up the car in the parking room and return to the parking room when the pallets are collected.

[0004]

According to the pallet method, since the car can be placed on a pallet and stored, there is no direct contact of the transport machine or the like with the car, so that the car is hardly damaged. Although there are advantages such as being able to be mounted on a pallet, on the other hand, supply of empty pallets at the time of entry into the warehouse and recovery processing of empty pallets at the time of exit from the warehouse are required, so that there is a problem that the entry / exit cycle time becomes long. In a multistory parking lot, the number of cars accommodated is determined from the entry / exit cycle time. For example, the number of cars that can be ejected in one hour and 30 minutes is the upper limit of the number of accommodated cars. Therefore, in order to create a large-scale parking lot with as many accommodations as possible, it is necessary to shorten the entry / exit cycle time. Therefore, it takes time to collect and supply the pallets, which is a factor that hinders the enlargement of the parking lot. It is what becomes. In the palletless method, there is no need to process an empty pallet, so that it is advantageous in terms of the loading and unloading cycle time as compared with the pallet method described above.

In view of such circumstances, the present invention provides a method of operating a pallet and a pallet in a mechanical parking lot capable of realizing a short entry / exit cycle time equivalent to that of a palletless system while utilizing all the advantages of the pallet system. The purpose is to:

It is characterized by. In the present invention, the entry / exit room for entrance / exit is a concept that includes not only the entrance / exit room for entry / exit and the entrance / exit room for exit / exit, but also one having a single entry / exit room for both entry and exit. The elevator according to the present invention also includes an elevator called a lift.

[0007]

According to the storage and retrieval method of the first aspect, between the entrance and exit passenger compartment and the elevator, and between the elevator and the bogie,
Furthermore, since the actual pallet and the empty pallet are simultaneously exchanged between the trolley and the storage shelf, the time required only for processing the empty pallet is eliminated, and the loading and unloading cycle time can be reduced to a short time as in the palletless method without using a pallet. can do. According to the loading / unloading method of the invention of claim 2, the pallets are transferred between the upper loading section and the lower loading section in the loading / unloading room, so that the pallets are smoothly circulated in the parking lot, and Elevators and bogies can be transported while the pallets are being transferred in the loading / unloading room, so that there is no dead time in the loading / unloading operation, and the loading / unloading cycle time can be reduced. According to the pallet operation method of the third aspect of the present invention, the exchange of the actual pallet and the empty pallet is performed simultaneously and sequentially at all the places where the exchange is necessary, and the pallet is transferred at the entrance / exit room for the next entrance / exit. Since the change is performed, the pallets smoothly circulate through the entry path and the exit path, and the waste time required for empty pallet processing can be eliminated, so that the entry / exit cycle time can be reduced.
