Background

The "elevator" is a lifting device for lifting a pallet on which a vehicle is placed between an entry/exit floor and a storage floor. The term "parking space" means an entrance space having an entrance position of a vehicle where a person gets on or off the vehicle on an entrance floor. The warehousing and ex-warehousing position in the berth is arranged separately from the hoisting machine.

As a mechanical parking device with a parking space, which has a lifter and a parking space and operates by placing a vehicle on a pallet, a planar reciprocating system, a planar circulation system, and the like are known.

For example, the parking surface reciprocating parking apparatus is preferably applied to an underground parking apparatus having a receiving frame provided at a plurality of floors, a traveling carriage horizontally moving along the receiving frame, and a hoist ascending and descending between the ground and the underground in an underground space. When the vehicle is put in the garage, the vehicle is put on a pallet in the berth, the pallet on which the vehicle is placed (hereinafter, referred to as a real pallet) is placed on the hoist again, and the real pallet is lowered to the underground space by the hoist. Next, in the underground space, the real vehicle pallet is placed on the movable carriage again, the movable carriage is horizontally moved to a position adjacent to the empty accommodating frame, and the real vehicle pallet is horizontally moved and accommodated in the accommodating frame. In addition, the actual vehicle pallet on which the vehicle is placed is moved to the ground by the reverse operation, and the vehicle is taken out from the parking space.

Such a reciprocating parking device with a parking plane is disclosed in patent document 1, for example.

However, in the case of a conventional flat reciprocating parking device with a parking space, in order for a next vehicle to enter the parking space after a preceding vehicle enters the parking space, it is necessary to transport a pallet (hereinafter, referred to as an empty pallet) on which no vehicle is placed from a storage rack to the parking space after the previous vehicle has been accommodated. Therefore, the waiting time becomes long when the warehouse is continuously put in.

In the case of continuous delivery, it is also necessary to transport the next actual vehicle pallet from the storage rack to the berth after the empty pallet after the delivery of the preceding vehicle is stored in the storage rack from the berth. Therefore, the waiting time for continuous delivery becomes long.

Therefore, a reciprocating parking device with a parking space plane has been proposed which shortens the waiting time at the time of continuous parking into a garage or continuous parking out of a garage (for example, patent document 2).

The "pallet handling apparatus" of patent document 2 is an apparatus that delivers empty pallets between a hoist that raises and lowers a pallet on which a vehicle is placed and an entry/exit floor. The pallet handling device is provided with a pallet storage rack integrally arranged under the floor of the elevator and used for accommodating empty pallets in a free taking and placing mode, and a pallet transfer device. The pallet transfer device performs, at the entrance/exit floor, transfer of a real pallet between the elevator and the entrance/exit floor during entrance/exit, and transfer of an empty pallet between the pallet storage rack and the entrance/exit floor.

Fig. 6 is a flowchart of an operation method in continuous warehousing according to the present invention. In this figure, the operation method according to the present invention includes the steps (processes) of S1 to S9.

Fig. 7A to 7D are explanatory diagrams when the garage is put in a continuous manner. Fig. 7A is an explanatory diagram of steps S1 to S2, fig. 7B is steps S3 to S4, fig. 7C is steps S5 to S6, and fig. 7D is steps S7 to S8.

The continuous binning method will be described below with reference to fig. 6 and 7A to 7D.

In the standby state of the hoist (step S1), the upper driving support portion 32 is in an empty state where the pallet 2 is not present, the lower driving support portion 34 is in a state where the empty pallet 2b is placed, the upper driving support portion 32 is located in the warehousing layer GL, and the hoist 30 is stopped. In step S1-2, the empty pallet 2b is positioned at the entry/exit position 3 of the dock 10 and stands by.

If the vehicle 1 enters the pallet at the entry-exit position 3 at step S1-3, the real vehicle pallet 2a is horizontally moved from the berth 10 to the upper driving support part 32 of the hoist 30 at step S2 (fig. 7A). At this time, the in-dock transport 50 is preferably interlocked with the upper drive support 32.

Next, in step S3, the elevator 30 is raised by the height difference Δ H, and the lower driving support 34 is positioned on the entry/exit layer GL and stopped. In this state (height), in step S4, the empty pallet 2B is horizontally moved from the lower drive support 34 to the berth 10 (fig. 7B). At this time, the in-dock conveying device 50 is preferably interlocked with the lower drive support 34.

After step S4, the in-dock conveyor 50 moves the empty pallet 2b to the in-and-out-of-garage position 3 of the dock 10 and returns to step S1-2, and the next vehicle 1 is put in the garage (step S1-3).

On the other hand, in the storage device standby (step S5-2), the storage device 20 is stopped in a state where the empty pallet 2b is positioned at a position close to the hoist 30 (hereinafter referred to as "pre-hoist position") at the storage level PL.

After step S4, the hoist 30 is raised and lowered (in this example, lowered) to the accommodating level PL in step S5, and the lower driving support 34 is positioned at the accommodating level PL and stops. In this state (height), the empty pallet 2b is horizontally moved from the storage device 20 to the lower drive support 34 in step S6 (fig. 7C). At this time, the pallet traverse device 27 is preferably interlocked with the lower driving support portion 34.

Next, in step S7, the hoist 30 is lowered by the height difference Δ H, and the upper driving support 32 is positioned at the accommodating level PL and stopped. In this state (height), in step S8, the real vehicle pallet 2a is horizontally moved from the upper drive support 32 to the storage device 20 (fig. 7D). At this time, the pallet traverse device 27 is preferably interlocked with the upper drive support portion 32.

After step S8, the storage device 20 performs the loading operation of the actual pallet 2a (step S9-2), and then conveys the empty pallet 2b to the position before the elevator and returns to the standby state (step S5-2).

After step S8, in step S9, the hoist 30 moves up and down (in this example, moves up) to the loading/unloading level GL as it is, and returns to the standby state (step S1).

According to the embodiment of the present invention, at the time of warehousing, the real pallet 2a is horizontally moved from the berth 10 to the upper driving support 32 at the warehousing entrance level GL, the lift 30 is raised by the step Δ H, and then the empty pallet 2b is horizontally moved from the lower driving support 34 to the berth 10. Therefore, at the time of parking, immediately after the preceding vehicle 1 (first vehicle) moves onto the elevator, the empty pallet 2b can be moved horizontally to the parking space 10 to cope with the parking of the next vehicle 1 (second vehicle) in a short time.

At the time of warehousing, the empty pallet 2b is horizontally moved from the storage device 20 to the lower driving support 34 at the storage level PL, the lift 30 is lowered by the height difference Δ H, and then the actual pallet 2a is horizontally moved from the upper driving support 32 to the storage device 20. Therefore, at the time of warehousing, before the preceding vehicle 1 moves onto the storage device, the empty pallet 2b can be moved horizontally onto the elevator to prepare the empty pallet 2b of the next vehicle 1 in a short time.

The above operations can be continuously performed until the empty pallet 2b of the storage device 20 is used up. Therefore, the waiting time at the time of continuous parking is the shortest operation time of steps S2 to S4 and the longest operation time of steps S5 to S9, and the parking operation in the parking space and the operation of the storage device 20 can be simultaneously performed in parallel. Thus, even when the number of vehicles is large, the waiting time can be shortened without interruption.

Fig. 8 is a flowchart of a method of operation during continuous warehouse-out according to the present invention. In this figure, the operation method according to the present invention includes the steps (processes) of T1 to T9.

Fig. 9A to 9D are explanatory diagrams of continuous shipment. Fig. 9A is an explanatory diagram of steps T1 to T2, fig. 9B is steps T3 to T4, fig. 9C is steps T5 to T6, and fig. 9D is steps T7 to T8.

The continuous delivery method will be described below with reference to fig. 8 and 9A to 9D.

In the hoist standby (step T1), at the accommodating level PL, the upper driving support portion 32 is in an empty state without the pallet 2, the lower driving support portion 34 is in a state where the empty pallet 2b is placed, the upper driving support portion 32 is positioned at the accommodating level PL, and the hoist 30 is stopped.

At step T1-2, if the accommodating device 20 positions the real truck tray 2a at the elevator front position, the real truck tray 2a is horizontally moved from the accommodating device 20 to the upper driving support 32 at step T2 (fig. 9A). At this time, the pallet traverse device 27 is preferably interlocked with the upper drive support portion 32.

Next, at step T3, the lifter 30 is raised by the height difference Δ H, and the lower driving support 34 is positioned at the accommodating level PL and stops. In this state (height), the empty pallet 2B is horizontally moved from the lower drive support 34 to the accommodating device 20 in step T4 (fig. 9B). At this time, the pallet traverse device 27 is preferably interlocked with the lower driving support portion 34.

After the step T4, the stocker 20 carries the empty pallet 2b and stores it in the empty stocker 8, performs the unloading operation of the next vehicle 1 (step T5-2), and returns to the step T1-2.

On the other hand, in the parking stand by (step T6-2), the empty pallet 2b is stopped in the loading/unloading level GL in a state of being positioned at the position before the hoist.

After step T4, at step T5, the lifter 30 is raised (in this example, raised) to the entry/exit layer GL, and the lower driving support 34 is positioned on the entry/exit layer GL and stopped. In this state (height), the empty pallet 2b is horizontally moved from the berth 10 to the lower driving support 34 in step T6 (fig. 9C). At this time, the in-dock conveying device 50 is preferably interlocked with the lower drive support 34.

Next, at step T7, the lifter 30 is lowered by the height difference Δ H, and the upper driving support 32 is positioned at the accommodating level PL and stopped. In this state (height), the real vehicle pallet 2a is horizontally moved from the upper drive support 32 to the berth 10 in step T8 (fig. 9D). At this time, the in-dock transport 50 is preferably interlocked with the upper drive support 32.

After the step T8, the vehicle 1 is unloaded from the parking space 10 (step T9-2), and then the empty pallet 2b is transported to the position before the elevator and returned to the standby state (step T6-2).

After step T8, at step T9, the hoist 30 directly moves up and down (in this example, moves down) to the exit/accommodation level PL, and returns to the standby state (step T1).

According to the embodiment of the present invention, at the time of shipment, the actual pallet 2a is horizontally moved from the storage device 20 to the upper driving support 32 at the storage level PL, the lift 30 is raised by the step Δ H, and then the empty pallet 2b is horizontally moved from the lower driving support 34 to the storage device 20. Therefore, at the time of delivery, immediately after the preceding vehicle 1 (first vehicle) moves onto the hoist, the empty pallet 2b can be moved horizontally to the storage device 20, so that the empty pallet 2b can be collected by the storage device 20 in a short time, and the delivery operation of the next vehicle 1 (second vehicle) can be performed.

At the time of unloading, the empty pallet 2b is horizontally moved from the berth 10 to the lower driving support 34 at the loading/unloading level GL, the hoist 30 is lowered by the height difference Δ H, and then the actual pallet 2a is horizontally moved from the upper driving support 32 to the berth 10. Therefore, at the time of delivery, before the preceding vehicle 1 moves to the berth 10, the empty pallet 2b of the berth 10 can be horizontally moved to the hoist to collect the empty pallet 2b in a short time, so as to cope with delivery of the preceding vehicle 1.

Each of the above operations can be continuously performed until the actual pallet 2a of the storage device 20 is used up. Therefore, the waiting time for the continuous warehousing is not affected by the recovery of the empty pallet 2b, and is always the operation time of the elevator 30 from step T2 to step T8, and the warehousing operation in the berth and the operation of the storage device 20 can be simultaneously performed in parallel. Thus, even when the number of vehicles is large, the waiting time can be always shortened without interruption.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
