Are arranged in layers (multi-stages) along the hoistway, and a loading / unloading section for loading and unloading a vehicle for parking is formed at the lowest position of the hoistway, for example. Further, the elevating table or each parking shelf is provided with a lateral transfer means for connecting the elevating table and each parking shelf and laterally transferring the pallet between them.

In such an elevator parking apparatus, when a vehicle is stored, an empty pallet on which the vehicle is not loaded is operated by a parking system manager or a user operating an operation panel provided outside the loading / unloading section. Is called to the storage section. When calling this empty pallet, the parking rack near the loading / unloading section is searched upward for the presence of an empty pallet, and when the empty pallet is searched, the elevator is loaded with the empty pallet. Move it to the parking shelf,
It is usual that the horizontal transfer means horizontally transfers the empty pallet to the elevating table and conveys it to the loading / unloading section.

(Problems to be solved by the invention) However, in the case of the above-mentioned empty pallet calling method, empty pallets are searched regardless of the position of the lifting platform, so it is not always necessary to quickly call the empty pallets to the loading / unloading section. It is not possible and the waiting time of the user becomes long.

That is, an object of the present invention is to make it possible to call an empty pallet to the loading / unloading section in a short time in an elevator type parking apparatus.

(Means for Solving the Problem) In order to solve such a problem, the present invention takes into account the working state of the lifting table when a pallet for storage is called,
This is a search for a pallet that can be called up in the storage section in the shortest time.

That is, a specific means therefor is an elevator having an elevating platform that supports and elevates a pallet on which a vehicle is mounted, and a plurality of elevators that are arranged in a hierarchy along the hoistway of the elevating platform to accommodate each vehicle together with the pallet. A parking rack, a loading / unloading section formed on the hoistway for loading and unloading vehicles, and a pallet lateral transfer for connecting the lifting platform and each parking rack to laterally transfer pallets between them. A control device for an elevator-type parking device including means, and a call command output means for calling a pallet for loading and unloading a vehicle to the loading and unloading section, and presence or absence of an empty pallet with no vehicle on each parking rack. A storage means for storing the pallet, and a lift table status detection means for detecting whether the lift table is in the loading operation, the loading operation, or the non-working status when a pallet call command is issued, When receiving the pallet call command and searching for the pallet to be called, the pallet on the elevator is searched based on the work information of the elevator by the elevator status detection means, and when the unloading work is in progress, the pallet on or off When one of the working states, the parking rack on the floor where the elevator is stopped or the floor where the elevator is stopped is the first priority, and parking on the floor between the elevator stop floor and the loading / unloading section The pallet search means for searching the empty pallet based on the empty pallet information by the storage means with the shelf as the second priority, and the elevator and the pallet lateral transfer means for conveying the searched pallet to the loading / unloading section. And a control means for controlling the drive.

The parking shelves are arranged in layers on both sides of the hoistway along the hoistway, and the pallet lateral transfer means is provided on the elevating table and is supported by a pair of pallet transfer directions on the elevating table. A sprocket, an endless conveyor chain suspended between the two sprockets, and an engagement member attached to the sprocket, engaged with the pallet by traveling of the conveyor chain and transferring the pallet between the lift and the parking rack. In the elevator type parking apparatus including the above, it is possible to solve the above problem by preferentially searching for empty pallets from the parking shelves on the side where the engaging member is moving among the parking shelves on both sides of the hoistway. It is effective in doing.

(Operation) In the above control device, when the elevator is in the process of leaving, the pallet on the elevator is used for the next loading, so the elevator can be moved to call an empty pallet after the work is finished. No need.

When the elevator is in storage or not in operation,
Since the empty pallets are searched in the first priority from the parking shelves on the floor on which the elevator stops, if there is an empty pallet on this elevator stop floor, move the elevator to the hoistway without moving the elevator. Can be withdrawn. If there are no empty pallets on the elevator stop floor, empty pallets are searched first from the parking shelves between the elevator stop floor and the loading / unloading unit. The lifting distance of the lifting platform for moving the to the loading / unloading section is shortened.

Further, in the case where the position of the engaging member of the pallet lateral transfer means on the lift table is checked and the empty pallet is searched from the parking shelf on the side where the engaging member is moving, the empty pallet is searched from the parking shelf. It is not necessary to move the engaging member to the parking rack side in advance when moving it to the lifting platform, and empty pallets can be quickly transferred from the parking rack to the lifting platform.

Therefore, according to the present invention, the method of searching for the pallet to be used for storing the next vehicle is changed according to the working state of the lifting platform, so that the pallet can be loaded or unloaded or not in working state. At some time, empty pallets are searched in the first priority from the parking shelves on the floor where the elevator stops, and empty pallets are searched in the second priority from the parking shelves between the elevator stop floor and the loading / unloading section. Therefore, it is possible to pull out an empty pallet onto the hoistway without moving the lifting platform or shorten the lifting distance of the lifting platform to move the empty pallet to the loading / unloading section.
It is possible to shorten the waiting time for users by calling an empty pallet to the loading / unloading section in a short time.

Further, in the case where the position of the engaging member of the pallet lateral transfer means on the lift table is checked and the empty pallet is searched from the parking rack on the side where the engaging member is moving, the empty pallet is moved from the parking rack. It becomes possible to transfer the pallets to the loading / unloading section quickly, which is advantageous in shortening the time required to call an empty pallet to the loading / unloading section.

Also, in step 1, the pallet 12 is placed on the lift table 7.
If it is determined that there is not, the current stop floor of the lifting platform 7 is searched to determine whether the engagement pins 45a, 45b of the pallet lateral transfer device 21 are at the left end of the lifting platform 7 (steps S18, S1).
9).

When the engaging pins 45a, 45b are at the left end, if there is an empty pallet 12 on the left-side parking rack 9 on the floor where the elevator is stopped, the empty pallet 12 is called to the loading / unloading section 11 (steps S20, S21). Therefore, in this case, it is not necessary to move up and down the elevating table 7 to call the empty pallet 12, and it is not necessary to move the engagement pins 45a and 45b largely in order to engage the empty pallet 12. If there is no empty pallet 12 on the left side parking rack 9 on the floor where the elevator is stopped, empty pallet 12 on the right side parking rack 9 on the same floor
It is searched whether or not there is, and if there is, the empty pallet 12 is called to the loading / unloading section 11 (steps S20, S22, S23).

When it is determined in step S19 that the engaging pins 45a and 45b are at the right end, the empty pallets are placed in the order of the right-side parking shelves 9 and the left-side parking shelves 9 on the elevator stop floor, contrary to the above. 12 will be searched (steps S22 and S20).

When there is no empty pallet 12 on the left and right parking shelves 9 and 9 on the elevator stop floor, it is determined whether the engaging pins 45a and 45b are at the right end of the elevator 7 as shown in FIG. If it is on the right edge,
The empty pallets 12 are searched upward in order from the bottommost parking rack 9 in the order of the right column and the left column (step S24).
