2. Description of the Related Art In single-row and double-row multi-story parking facilities used as storage devices for storing vehicles, conventionally, in order to release vehicles, as shown in FIG. Immediately after accepting, select the exit route, create a transport command for the equipment on the exit route,
A method of registering in a transport queue, that is, a table that stores a transport instruction (information defining the operation of the mechanical device) for each transport device in a computer is adopted.

More specifically, with reference to FIGS. 4 to 7, the leaving schedule management in a conventional mechanical parking facility is performed as follows. (A) The control device 101 is for issuing a retrieval request 201 from the entry card reader 102 or the exit card reader 103, that is, for releasing a stored vehicle using a parking ticket, a commuter pass, or a predetermined number in a mechanical parking facility. By inputting a request, a device on the delivery route is selected, a transfer command is created, and registered in the transfer queue.

(B) The transport queue manages the status of transporting and waiting for transport for each transport device. As shown in FIG. 6, transport completion information (machine stoppage) from a delivery berth (parking space for delivery) 8 is shown in FIG. When the apparatus inputs the information of the completion of the transfer, the first transfer instruction of the transfer waiting is transmitted to the unloading berth 8, and the transfer is changed from the waiting state to the carrying state. At the same time, the second waiting order is moved up to 1, and the third waiting order is moved up to 2. In FIG. 4, reference numeral 202 denotes the control device 10.
The transport command 203, which is input from 1 to the transport device,
3 illustrates a transfer completion signal input from the transfer device to the control device 101.

When an outgoing request is issued to request an outgoing delivery by designating the stored object to be stored, it is registered as an outgoing reservation, and the actual outgoing outgoing transmission number to the bogie (the actual outgoing outgoing Is controlled to limit the number of outgoing transmissions of the storage object to the maximum outgoing transmission number which is a set value in consideration of the number of trucks,
It becomes possible to secure a truck for parking. Also,
Even during a congestion in which the retrieval request exceeds the maximum retrieval transmission number, the retrieval request is accepted as a retrieval reservation, and retrieval is efficiently performed according to the retrieval status.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A multi-story multi-story parking facility with a multi-story floor will be described below with reference to FIGS. 1 to 3 as one embodiment of a storage device according to the present invention.

As shown in FIGS. 1 to 3, the multi-story parking facility includes a plurality of movable vehicles 5 and respective vehicles 5.
, A storage shelf group 11 of storage shelves 10 installed in correspondence with the above, a transport means for transporting a vehicle (object to be transported) C, and a control device (control means) 101 for controlling the transport means.
Further, similarly to the conventional case shown in FIG. 4, the transport means includes a parking lot entrance 1 as a transport means for transporting an incoming vehicle (object to be transported) to the carriage 5, an incoming berth (an incoming parking space). 2 and warehouse lifter (warehouse elevator) 3
As a means for exchanging vehicles between the cart 5 and the storage shelf 10, a cart traveling path 4 shown in FIG. The vehicle includes an exit lifter (exit elevator), an exit berth (exit stop space) 8 and a parking exit 9 as means.

The control device 101 includes a storage card reader 102 and a storage card reader 103 for making a request for storage and release, and the number of outgoing transmissions (outgoing) for transmitting a transfer instruction to the transfer means for discharging the vehicle C. A maximum number of outgoing transmissions is set in advance according to the number of trucks as the maximum value of the number of actual outgoing transmissions out of the number of orders, and an outgoing request that requests outgoing by specifying the stored vehicle C occurs. When this is done, it is registered as a leaving reservation and the transport means is controlled so as to limit the actual number of outgoing transmissions to the trolley to the maximum number of outgoing transmissions.

More specifically, a description will be given of a leaving schedule method in this multi-story parking facility. As shown in FIGS. 1 and 3, the control device 101 inputs a leaving request 201 of the entering card reader 102 or the leaving card reader 103, and Of the number of outgoing orders, check the number of items that have been sent, that is, the number of outgoing sent items, and set the value (maximum number of outgoing sent items).
If it is equal to the set value, it is registered in a waiting queue (table storing the leaving request) and temporarily stored.

The retrieval request 20 registered in the retrieval waiting queue
When the transfer completion (information that the mechanical device has been completed) is input from the unloading berth 1, 1 retrieves the earliest registered outgoing request from the outgoing waiting queue and creates a transfer instruction (information that specifies the operation of the mechanical device). And register it in the transport queue. When the number of outgoing transmissions is smaller than the set maximum outgoing transmission number, a transfer instruction is created without storing the outgoing request in the outgoing waiting queue, registered in the transfer queue, and one is added to the outgoing transmission number.

Therefore, as shown in FIG. 2, the number of outgoing transmissions of the transport queue can be suppressed to a set value.
It becomes possible to open one or a plurality of carts for taking out. For example, when the set value of the maximum number of outgoing transmissions is set to 3, the state of the transport queue and the outgoing waiting queue as shown in FIG. 2 is established. In this case, when the retrieval request includes orders in the five storage vehicles in order from “departure” to “departure” in numerical order (that is, the number of departure orders is five), since the maximum number of departure transmissions is set to three, From issue to issue, it is registered in the transport queue as the number of issues sent,
Until the remaining delivery and delivery are registered in the delivery waiting queue.

That is, in the transport queue, "outgoing" is being carried out to the outgoing berth, "outgoing" is being carried out in the outgoing lifter, and "outgoing" is being carried out in the upper bogie, and it can be seen that the lower bogie is ready to be used for incoming.

In this embodiment, the storage device is applied to a multi-story parking facility for storing vehicles, but may be applied to other storage devices. For example, the object to be conveyed may be cargo or luggage, and may be used in a three-dimensional automatic warehouse or the like that stores these.

[0017]

According to the storage device of the present invention, the control means sets the maximum number of outgoing transmissions as a maximum value of the number of outgoing transmissions for transmitting a transport instruction to the transporting means to retrieve the storage object in advance. When an outgoing request is issued to request an outgoing delivery by designating a stored object to be stored, it is registered as an outgoing reservation and the actual outgoing outgoing transmission number to the bogie is set to the maximum. Since the transport unit is controlled so as to limit the number to the number of outgoing transmissions, the following effects can be obtained. (1) Since the number of outgoing transmissions is managed to be equal to or less than the maximum number of outgoing transmissions, it is possible to leave a truck for warehousing even during congestion, so that the warehousing person's waiting time for warehousing can be reduced. (2) Further, the number of incoming vehicles can be increased and the storage efficiency can be improved. (3) Since the delivery request is registered and managed as a delivery reservation,
Even during the congestion of retrieval, a retrieval request for the storage object can be accepted, and a service can be provided to the retrieval person.
