Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an outgoing management in which a plurality of loads including different types of loads are stored out of a plurality of stored destinations in a predetermined release order. It concerns the device.

[0002]

2. Description of the Related Art FIG.
It is a schematic plan view which shows the example of. This delivery management device 10
Is provided with automatic warehouses 11A to 11C for storing loads, and a plurality of unloading conveyors 18A to 18C as destinations for unloading the loads carried out from the automatic warehouses 11A to 11C. Between the unloading conveyors 15A to 15F of the automatic warehouses 11A to 11C and the unloading conveyors 18A to 18C, the loads sequentially transferred to the unloading conveyors 15A to 15F are loaded onto the unloading conveyors 18A to 18C. A plurality of track-type transport carts 17A to 17C for sorting and transporting sequentially are provided.

[0003] The delivery management device 10 performs a delivery operation of sequentially delivering a plurality of loads including loads of different types to one of the delivery conveyors 18A to 18C in a predetermined delivery order. this is,
For example, by loading a group of loads delivered in a predetermined delivery order on a truck or the like in the same order, trucks can be efficiently delivered in order along a predetermined delivery route.

[0004] The retrieval management device 10 is controlled by a control system as shown in FIG. The control system includes an inventory management computer 23, a warehouse management computer 24, crane control panels 19A to 19C, a conveyor control panel 20, a bogie control panel 21, and the like.

[0005] The inventory management computer 23 is an automatic warehouse 1
It is a computer that performs inventory management of loads stored in 1A to 11C. The inventory management computer 23 creates outgoing data instructing that a plurality of loads should be outgoing to one outgoing destination as one outgoing unit based on a predetermined outgoing outgoing plan or the like. The leaving data includes information indicating the storage unit 12 in each of the automatic warehouses 11A to 11C in which a plurality of loads including different types of loads are stored. In addition, the delivery data has information for designating a delivery destination for releasing each load of one delivery unit from the delivery conveyors 18A to 18C.

The delivery control computer 24 exchanges data with the crane control panels 19A to 19C, the conveyor control panel 20 and the bogie control panel 21 on the basis of the delivery data to form each of the cranes 14A to 14C and each of the conveyors 15A to 15C. 1
5F, 18A to 18C, and transport carts 17A to 17C
Directly monitor and control.

That is, the retrieval control computer 24 controls the stacker cranes 14A to 14C of the automatic warehouses 11A to 11C storing the loads specified by the retrieval data via the crane control panels 19A to 19C based on the retrieval data. And transports the load stored in the storage section 12 of the load storage shelf 13 onto the unloading conveyors 15A to 15F.
Next, the unloading control computer 24 controls the unloading conveyors 15A to 15F on which the loads are placed via the conveyor control panel 20, and moves the loads to the transfer positions to the transport vehicles 17A to 17C.

[0008] Further, the delivery control computer 24, based on the delivery data, the unloading conveyors 15A to 15C to which the load was unloaded.
An optimal transport cart 17A-17C for transporting the load from 15C to the delivery conveyor 18A-18C at the delivery destination is selected. Then, the selected transport carts 17A to 17C are controlled via the cart control panel 21, and are moved to the transfer positions from the unloading conveyers 15A to 15F that have unloaded the load.
When the transport carts 17A to 17C are moved to the transfer position, the delivery control computer 24 sets the unloading conveyor 15
A to 15F and the transport carts 17A to 17C are controlled to transfer the unloaded load from the unloading conveyors 15A to 15F to the transport carts 17A to 17C.

Next, the retrieval control computer 24 controls the transport vehicles 17A to 17C to which the load has been transferred via the vehicle control panel 21 and retrieves the loads from the retrieval conveyors 18A to 18C.
Move to the delivery position to 18C. Transport trolley 17
When the delivery control computer 24 moves the A-17C to the delivery position, the delivery control computer 24 controls the transport vehicles 17A-17C and the delivery conveyors 18A-18C, and transfers the conveyed load onto the delivery conveyors 18A-18C. Finally, the delivery control computer 24 reads the delivery conveyor 1 to which the load has been transferred.
8A to 18C are controlled via the conveyor control panel 20, and the load is moved to a position where the load is transferred to a truck or the like of the unloading conveyors 18A to 18C.

In this way, the retrieval control computer 2
4 is a delivery conveyor 18A-1 designated as a delivery destination for each load of the delivery unit specified by one delivery data.
An outgoing work for sequentially taking out the 8C in a predetermined outgoing order is performed.

In this unloading operation, when controlling the stacker cranes 14A to 14C via the crane control panels 19A to 19C, the unloading control computer 24 moves the stacker crane which has been moved to the storage unit 12 where the load to be unloaded is stored. The presence or absence of a load in the storage unit 12 is detected by load detection sensors provided in 14A to 14C. Then, when a load is detected in the storage unit 12, the retrieval control computer 24 controls the stacker cranes 14A to 14C to carry out the load, assuming that the load is the load instructed to be carried out.

Similarly, the unloading control computer 24 controls the unloading conveyors 15A to 15A via the conveyor control panel 20.
When controlling F, the presence or absence of a load on the unloading conveyors 15A to 15F is detected, and when the load is detected, the load is conveyed to the transfer position as a commanded load. When controlling the transport carts 17A to 17C via the cart control panel 21, the delivery control computer 24 detects the presence or absence of a load transferred from the unloading conveyors 15A to 15F. Outgoing conveyer 18 that the cargo is designated as the cargo instructed to be transported
The sheet is transported to the transfer position to A to 18C. Further, when controlling the unloading conveyors 18A to 18C via the conveyor control panel 20, the unloading control computer 24 detects the presence or absence of a load transferred from the transport carts 17A to 17C, and detects the load. Then, the cargo is conveyed to the delivery position assuming that the cargo has been instructed to be carried. Then, the retrieval control computer 24 determines that the retrieval operation of one load has been completed based on the completion of a series of transport operations by each transport device.

On the other hand, when performing the unloading operation by controlling the transport equipment via each of the control panels 19 to 21, the unloading control computer 24 does not detect a load at a predetermined position where each transport equipment should receive the load. Then, the transport operation by each transport device after the transport device is stopped, and the unloading operation of the load is stopped.

Actually, the delivery control computer 24 has the delivery conveyors 18A to 18 which are the delivery destinations.
Based on a plurality of retrieval data items created so that Cs differ, retrieval operations for each retrieval unit for the retrieval conveyors 18A to 18C are alternately executed. At this time, there were two types of methods for causing the retrieval control computer 24 to perform a retrieval operation based on a plurality of retrieval data.

The first is that the inventory management computer 23
This is a method in which the dispatch control computer 24 is instructed alternately and sequentially in a predetermined order set for each of the dispatch data, for the dispatch operation of each load indicated by each of the plurality of exit data. For example, in the case of performing the unloading operation on the three outgoing conveyors 18A to 18C based on the three outgoing data, for example, from the load specified by the outgoing data instructing the outgoing to the outgoing conveyor 18A, 1 In this case, the delivery instruction data for causing the cargo to be delivered in the second delivery order to be delivered is created, and the delivery instruction data is sent to the delivery control computer 2.
4 is output. The delivery instruction data indicates storage positions in the automatic warehouses 11A to 11C for each load, and designates delivery conveyors 18A to 18C to be delivered.

Upon receiving one piece of delivery instruction data, the delivery control computer 24 carries out an operation of delivering one load specified by the delivery instruction data to the delivery conveyor 18A. Upon completion of the retrieval operation based on the retrieval instruction data, the retrieval control computer 24 outputs a retrieval completion signal to the inventory management computer 23. When the inventory management computer 23 receives the delivery completion signal corresponding to the delivery instruction data instructing the delivery of the load to the delivery conveyor 18A, the inventory management computer 23 next loads the cargo indicated by the delivery data instructing the delivery to the delivery conveyor 18B. Then, it generates exit instruction data for unloading the cargoes to be output in the first order, and outputs it to the exit control computer 24. Similarly, when the inventory management computer 23 receives a delivery completion signal corresponding to the delivery instruction data instructing delivery to the delivery conveyor 18B, the inventory management computer 23 changes the load indicated by the delivery data instructing delivery to the delivery conveyor 18C from the load. Outgoing instruction data for unloading the cargo instructed to be delivered in the first outgoing order is created and output to the outgoing control computer 24.

When the unloading operation of each load to be unloaded in the first outgoing order among the loads specified by all the unloading data is completed, the inventory management computer 23 designates each unloading data in the same manner. The loading control computer 23 is caused to sequentially perform the loading operation of each load to be discharged in the second discharging order from the loads. Further, the inventory management computer 23, in the same manner as the first and second shipments, loads out of the loads specified by the respective outgoing data in the third and subsequent shipping orders.

However, in this method, the stock management computer 23 has to send and receive the delivery instruction data and the delivery completion signal to and from the delivery control computer 24 every time one load is delivered. There has been a problem that the time required for the unloading work of the entire load specified by each unloading data becomes longer by the time required for communication.

Also, since there are a plurality of stacker cranes 14A to 14C or a plurality of transport trolleys 17A to 17C, the retrieval control computer 24 has a plurality of cranes 14A to 14C.
C or a plurality of loads can be simultaneously transferred to the transfer carts 17A to 17C. However, in the case where the unloading control computer 24 performs the unloading operation for each load in the above-described manner, each transfer device only performs the transfer operation of one load at a time. And it was not possible to increase the efficiency of the shipping work.

On the other hand, in another system, the inventory management computer 23 instructs the retrieval control computer 24 to carry out each load indicated by a plurality of retrieval data and the order in which the respective loads are transported. The delivery control data is sent in advance. The delivery control computer 24 does not exchange data with the inventory management computer 23 based on the stored delivery control data,
Carrying out work is carried out for each warehousing unit specified by each warehousing data.

The delivery control data D is, as shown in FIG.
Storage unit data indicating the storage position for each load specified by each outgoing data, outgoing conveyor 18A for outgoing destination
To 18C, and outgoing order data indicating the outgoing order in the outgoing unit to which the cargo belongs. The retrieval control computer 24 performs the retrieval operation for each load in the predetermined order set for each retrieval unit based on the retrieval control data D, and outputs the data to the retrieval order assigned to each load of each retrieval unit. This is performed in a predetermined retrieval order for each retrieval unit.

Therefore, in this method, the delivery control computer 24 and the inventory management computer 23
There is no need to perform communication for each unloading operation of one load, and there is no delay in the unloading operation time associated with communication as in the above-described method.

In this system, the retrieval control computer 24 causes each transport device to simultaneously transport a plurality of loads at a time based on the retrieval control data stored in advance. For example, the retrieval control computer 24
Stacker crane 14 for carrying out one load
A to control one of the stacker cranes 14A to 14C at the same time when another one to be used in the unloading operation is another stacker crane 14A to 14C.
14C is controlled so that the unloading work of two loads is performed simultaneously. Similarly, unloading conveyors 15A to 15C,
Alternatively, a plurality of the transport vehicles 17A to 17C are simultaneously controlled to simultaneously carry out a plurality of load transport operations. Therefore, since the transport capacity of each transport device is not wasted, the efficiency of the unloading operation can be improved.

[0024]

The automatic warehouse 1
When it is determined that the load carried out from 1A to 11C onto the carry-out conveyors 15A to 15F or the load being conveyed by the carriages 17A to 17C is defective.
An operator may manually remove the load from the delivery management device 10.

In this case, the delivery management device 10 performing the delivery operation in the former method uses the unloading conveyors 15A to 15A.
When the load is removed from the transport carts 17A to 17C or the transport carts 17A to 17C, the load is not detected by the transport carts 17A to 17C or the outgoing conveyors 18A to 18C, and the outgoing control computer 2
4, no load detection signal is output. Then, since the transport operation of the carriage control device 21 or the conveyor control panel 20 for performing the unloading operation of the removed load is not completed, the unloading control computer 24 does not output the unloading completion signal, and the inventory management computer 23 performs the next operation. Unloading work based on the unloading instruction data cannot be performed.

Therefore, in the retrieval management device 10, when the unloaded cargo is removed, the operator operates the retrieval control computer 24 to output a retrieval completion signal to the inventory management computer 23. . Then
The inventory management computer 23 determines that the unloading operation of the removed load is completed, and sequentially outputs each unloading instruction data to perform the unloading operation of the remaining load. Therefore, when the load in the middle of removal is removed, the operator operates the delivery control computer 24 to output a delivery completion signal, so that the remaining removal work excluding only the removed load can be performed as it is. it can.

On the other hand, even in the delivery management apparatus 10 which performs the delivery work in the latter method, if the load in the middle of removal is removed, the delivery control computer 24 does not determine that the delivery work of the load has been completed. The unloading work of the load for performing the unloading work is not performed.

In the delivery management device 10, the delivery control computer 24 performs the delivery work for each load in a predetermined delivery work order based on the delivery order data attached to each load. For this reason, when the load in the middle of the delivery is removed, the delivery work corresponding to the delivery order data attached to the load is not completed, and the delivery work of the load after the delivery work order is not performed.

Therefore, when a load in the middle of unloading is removed, the operator operates the unloading control computer 24 so that the unloading work in the unloading work sequence corresponding to the unloading order data of the load is not missing. It is necessary to correct the delivery order data attached to the load in the delivery work order after the delivery order data by one.

However, when there is a large number of shipments instructed to be delivered in the delivery data, every time the delivery management device 10 removes a partially unloaded shipment, the operator performs such data correction work. It was troublesome to do.

When it is previously known that one of the loads indicated by the outgoing data created by the inventory management computer 23 is defective, it is necessary to prevent the outgoing of the outgoing load. Therefore, it was necessary to correct the outgoing control data attached to each load in the outgoing unit.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a delivery management for carrying out a delivery operation of a plurality of loads to a plurality of delivery destinations in a predetermined delivery order. It is an object of the present invention to provide a delivery management device which can remove remaining loads in a predetermined delivery order without performing a work of correcting data of the loads to be delivered even if a load in the middle of removal is removed.

Also, even if there is a load for which delivery is prohibited among loads requested to be delivered, a delivery management device capable of taking out the remaining load without correcting data of the delivered load. Is to provide.

The retrieval control computer 24 moves, for example, the transport truck 17A via the truck control panel 21 to the delivery position to, for example, the retrieval conveyor 18A for releasing the conveyed load, based on the sequentially input retrieval instruction data. . Further, the retrieval control computer 24 is provided with the bogie control panel 21.
The transport truck 17A is controlled via the conveyor control panel 20, and the delivery conveyor 18A is controlled via the conveyor control panel 20, and the conveyed load is transferred from the transport truck 17A onto the delivery conveyor 18A. Further, the retrieval control computer 24 controls the retrieval conveyor 18A to transport the load transferred from the transport vehicle 17A to a transfer position to a truck or the like.

At this time, the retrieval control computer 24
For example, when the transport trolley 17A that transports the load indicated by one piece of delivery instruction data is moved to, for example, a delivery position to the delivery conveyor 18B, or the delivery trolley 17A is moved to the delivery position from the delivery trolley 17A.
When a load is transferred onto the delivery conveyor 8B, the delivery cart 17B is transferred to the delivery conveyor 18A based on the delivery instruction data input in the following order or the delivery instruction data input in the next order. When the transport truck 17A is moved to the position, the transport truck 17A and the delivery conveyor 18A are controlled without waiting for the transfer of the load from the delivery truck 17A to the delivery conveyor 18B to transfer the newly transported load. It is intended to be posted.

When the input retrieval instruction data has a data section indicating that the retrieval order is unnecessary, the retrieval control computer 24 is instructed by each retrieval instruction data to which the data section is attached. The transport carts 17A to 17C are controlled so that the respective loads are conveyed to the delivery conveyors 18A to 18C at the delivery destination without being restricted in the order in which the respective delivery instruction data are input.

Each of the crane control panels 19A to 19C causes the stacker cranes 14A to 14C to carry out the work based on a command from the warehouse control computer 24. Each of the crane control panels 19A to 19C has a stacker crane 14A to
14C is detected and the stacker cranes 14A to 14C are detected.
When C moves to the storage unit 12 of the delivery source, the presence or absence of a load in the storage unit 12 is detected. Then, when a load is detected, a detection signal is output to the exit control computer 24 and the unloading operation is continued, and when no load is detected, the transport operation is stopped.

The carriage control panel 21 also controls the transport carriages 17A to 17A based on commands from the exit control computer 24.
Let C perform the transport operation. The trolley control panel 21 detects the position of each of the transport vehicles 17A to 17C, and detects the position of each of the transport vehicles 17A to 17C.
When the transfer conveyor 17C moves to the transfer position from the unloading conveyors 15A to 15F, the unloading conveyor 15

When a defect is found in one of the loads requested to be retrieved in the retrieval data, a predetermined operation is performed on the inventory management computer 23 to specify one of the loads constituting one of the retrieval units. The delivery instruction data of the placed cargo is not output.

Therefore, the delivery control computer 24 has:
The delivery command data of the designated load is not input, and the delivery control computer 24 performs delivery of the remaining loads of the delivery unit to which the designated load belongs in the delivery order instructed by the delivery data and other delivery. The delivery of each delivery unit indicated by the data is performed in the respective delivery order.

When the load carried to the carry-out conveyors 15A to 15F and the load being carried by the carriages 17A to 17C are removed, the delivery control computer 24
Stops the unloading operation of the removed load based on the interruption of the detection signals from the control panels 19 to 21 of each transport device. Then, the retrieval control computer 24 sequentially performs retrieval operations based on each retrieval instruction data sequentially input after the retrieval instruction data of the removed load. Therefore, the unloading work of the load other than the removed load is performed in the order in which the unloading instruction data of each load is input.

At this time, since the inventory management computer 23 does not output a delivery completion signal to which the identification data of the removal instruction data of the removed load is attached, the inventory management computer 23 does not release the load. Recognize that

Further, when it is not requested that the delivery unit specified by the delivery data is issued in a predetermined delivery order,
When a predetermined operation is performed on the inventory management computer 23, the delivery unit is designated, and the delivery instruction data for instructing delivery of each load in the designated delivery unit includes a data section indicating that the delivery order does not need to be considered. Attached. Then, the retrieval control computer 24 determines whether or not the retrieval instruction data in which the data section is added to each of the retrieval instruction data that are sequentially input, regardless of the order in which the respective retrieval instruction data are input, is transferred by the transport vehicles 17A to 17C. A cargo unloading operation based on each of the unloading instruction data is performed so as to increase the efficiency. Therefore, with respect to the delivery unit of the delivery data that does not indicate the delivery order, each load is delivered regardless of the delivery order.
