BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for leaving an automatic warehouse.

[0002]

2. Description of the Related Art Conventionally, a load stored in a storage section of an automated warehouse is composed of a box and parts stored in the box. When the parts are stored in the box, the load can be loaded or unloaded. Be seen.
For example, up to 10 parts can be stored in this box.
A fixed number of 10 parts are stored in the box. However, since parts are extracted from the box by, for example, unloading for picking work (picking unloading), not only loads having a fixed number of 10 parts but also fractional parts of 9 or less are stored in the automatic warehouse. The load you have is stored. For convenience of explanation, it is assumed that the number of types of parts stored in the automatic warehouse is one (the same type).

When the cargo is to be unloaded from this automatic warehouse,
The worker inputs delivery request data (for example, data such as the number of parts to be delivered) to the inventory management computer that manages the inventory of the automated warehouse. The inventory management computer sequentially reserves (assigns) the storage parts in which the parts are to be delivered in order to deliver the requested number of parts.

Allocation of the storage section to be delivered (delivery allocation)
Is a so-called "first-in / first-out
According to the "principle of delivery", the cargoes are loaded in order from the oldest one on the day of receipt.

[0005]

Consider a case where, using this automatic warehouse, 22 parts are delivered from the automatic warehouse. In this automated warehouse, for example, the number of parts of the load having the oldest receipt date is 3, the number of parts of the load having the oldest receipt date is 10 (quantity), and the number of the parts having the oldest receipt date is next. It is assumed that there are 10 parts (quantitative number).

Then, from the automated warehouse, first, the quantity 3
Individual loads are delivered, then a fixed number of loads, and finally a fixed number of loads. For this reason, the worker needs to perform a picking operation of taking out 9 parts from the final fixed quantity of the load in order to set the number of the delivered parts to 22 pieces. Therefore, there is a problem in that the picking work requires time and labor for the work to deliver the load, and the workability deteriorates.

Further, the delivered parts are stored in the large case together with the box in the required quantity (22 pieces in this case). When stored in this large case, the number of parts in each box is preferably 10, 10, and 2, respectively. However, since the number of parts of each cargo that has been unloaded is 3, 10, and 9, respectively, the worker may, for example, add the last 9 parts and the first 3 parts that have been unloaded. You need to add one of For this reason, there is a problem in that loads cannot be stored in the large case in the order in which they are unloaded, resulting in poor workability.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a method and an apparatus for discharging an automatic warehouse that can efficiently discharge a load.

FIG. 3 shows a load W stored in the storage section 3. The load W is composed of a box U and a part X as an article stored in the box U. A plurality of types of parts X are transported to the automated warehouse 1 and stored in the storage unit 3. Incidentally, in the present embodiment, three types of parts X having a product number A, a product number B, and a product number C are transported and stored. Further, one type of component X is stored in one box U, and up to 10 of the one type of component X can be stored. Usually, the quantity of the parts X stored in the box U is 10, and the quantity 10 is the fixed quantity N of the parts X stored in the box U.

In the shipping operation performed in the automatic warehouse 1 thus constructed, first, the stacker crane 5 takes out the load W from the intended storage section 3. Then, the stacker crane 5 conveys the load W to the loading / unloading table K and places the load W on the loading / unloading table K. In this state, the worker takes out the parts X together with the box U according to the requested delivery quantity n, or takes out the necessary number of parts X from the parts X stored in the box U. (Picking work).

In the case of the unloading (normal unloading) work for taking out the entire box U as described above, the unloading work is completed when the box U is placed on the loading / unloading table K, and the stacker crane 5 performs the next unloading. Or move to the delivery work. Further, in the case of a picking-out operation for performing picking work, when the picking work is completed, the stacker crane 5 again picks up the load W on the loading / unloading table K and conveys it to the storage section 3. By storing the load W in the storage section 3, the unloading work is completed, and the stacker crane 5 moves to the next warehousing or unloading work.

Next, the electrical configuration will be described. FIG.
As shown in, the inventory management computer 21 is composed of a CPU and also has a memory 21a as a storage means. In addition, the inventory management computer 21 has a keyboard 2
2 and the display 23 are connected. Further, an optical communication device Hb is connected to the inventory management computer 21.

On the other hand, an optical communication device Ha is connected to the crane controller 10, and the crane controller 10 and the inventory management computer 21 can communicate with each other via the optical communication devices Ha and Hb. A traveling motor M1, a lifting motor M2, and a slide motor M3 are connected to the crane controller 10. The crane controller 10 also has a memory 10a.

The keyboard 22 outputs various data to the inventory management computer 21 based on the operation of the operator. That is, the keyboard 22 outputs the delivery request data to the inventory management computer 21. The delivery request data is data for requesting delivery of the load W, and includes data indicating the product number and quantity of the component X to be delivered.

Memory 21a of inventory management computer 21
Stores inventory data of all storage units 3 of the automated warehouse 1. The inventory data is data indicating the product number, quantity, etc. of the component X stored in the storage unit 3. The inventory data in a state where the load W is not stored in the storage unit 3, that is, in the state of an empty shelf is data indicating that the storage unit 3 is empty.

The inventory management computer 21 prepares the delivery work instruction data based on the inventory data and the delivery request data. The shipping operation instruction data is data for instructing the crane controller 10 (stacker crane 5) to convey the load W, and data for specifying the target storage unit 3 in which the load W to be output is stored and shipping operation. It consists of data showing the work content for

The crane controller 10 drives the traveling motor M1, the lifting motor M2, and the slide motor M3 based on the leaving work instruction data to cause the stacker crane 5 to perform the leaving work.

The inventory management computer 21 is adapted to make a delivery allocation and a picking allocation in order to create the delivery operation instruction data. Outgoing allocation is to select the storage section 3 in which the target load W is stored in order to normally output the target load W, and picking allocation is to pick out the target load W from the storage unit 3. This is to select the storage unit 3 that stores the load W.

At the time of this allocation processing, the inventory management computer 21 determines in advance whether the quantity (delivery quantity) n of the part X of the product number requested to be delivered is less than or equal to the shelf inventory quantity E. Has become. The inventory quantity E is the total quantity of the parts X for each product number stored in the automated warehouse 1,
In this case, it means the total amount of the parts X having the product number requested to be stored in the automatic warehouse 1. If the delivery quantity n is equal to or less than the inventory quantity E on the shelf, the load W from the automated warehouse 1
It is assumed that the delivery of goods is possible, and the processing of the delivery allocation and the picking allocation is performed. If the delivery quantity n is larger than the shelf inventory quantity E, it is determined that the delivery of the load W from the automated warehouse 1 is impossible, and an inventory shortage process is performed. As the stock shortage process, for example, the stock number and the shortage number of the target load are displayed on the display 23.

When the delivery quantity n is less than or equal to the shelf inventory quantity E, the inventory management computer 21 determines whether or not the delivery quantity n of the part X requested by the delivery request data is less than the fixed quantity N. ing. And the inventory management computer 2
1 indicates that if the delivery quantity n is equal to or greater than the fixed quantity N, the storage unit 3 that stores the load W containing the fixed quantity N of the component X (hereinafter, referred to as "load W with fixed quantity N"). Outgoing allocations are made sequentially. Then, when the remaining delivery quantity n ₁ becomes less than the fixed quantity N, the inventory management computer 21 searches whether or not there is a storage section 3 on which the same number of parts X as the remaining delivery quantity n ₁ are placed. However, when the target storage unit 3 is searched, one of the storage units 3 is selected and the delivery reservation is made for the storage unit 3.
In addition, the remaining delivery quantity n ₁ is determined by the delivery allocation.
The quantity is a quantity that has not yet been reserved for shipping, and is a quantity obtained by subtracting the quantity of the parts already reserved for shipping from the quantity n requested by the shipping request data.

Similarly, the inventory management computer 21 determines whether or not there is a storage unit 3 that stores the same number of parts as the delivery quantity n even when the delivery quantity n requested by the delivery request data is less than the fixed quantity N. Is searched, and when there is a desired storage unit 3, one of the storage units 3 is selected, and the delivery reservation is made for the storage unit 3.

[0037] The goods issue quantity n, during the search to find the n ₁ and a housing portion 3 housing the same number of parts X, goods issue number n, if there is n ₁ and the housing portion 3 mounted with the same number of parts X, The inventory management computer 21 stores the load W (hereinafter, referred to as “minimum quantity y of the minimum quantity y” that contains the smallest quantity y of the smallest quantity of the quantity W stored in the box U among the loads W stored in the automated warehouse 1). It is designed to search the storage section 3 in which the load W ”is stored.

The inventory management computer 21 determines that the minimum quantity y
When the search of the storage unit 3 storing the load W of _No. 3 is completed, it is determined whether the minimum quantity y is less than or equal to the delivery quantity n, n ₁ , and if the minimum quantity y is less than or equal to the delivery quantity n, n ₁ , One of the storage units 3 that stores the minimum number y of parts X
Is selected to carry out delivery allocation.

If the minimum quantity y is larger than the delivery quantity n, n ₁ , the inventory management computer 21 selects one of the searched storage sections 3 to perform picking allocation. There is.

Upon completion of the delivery allocation and the picking allocation, the inventory management computer 21 issues a delivery operation instruction for performing the normal delivery and the picking delivery to the allocated storage unit 3 based on the delivery allocation and the picking allocation. Create the data. This shipping work instruction data includes
It is instructed to perform the normal shipping and the picking shipping corresponding to each allocation according to the order of the shipping allocation and the picking allocation. Therefore, the crane controller 10 to which the shipping operation instruction data is output performs the shipping operation and the picking operation of the load in accordance with the order of the shipping allocation and the picking allocation based on the shipping operation instruction data. ing. That is, the normal delivery and the picking delivery are sequentially performed for the storage unit 3 to which the delivery provision and the picking provision have been made in advance.

Next, the operation of the delivery apparatus for the automatic warehouse constructed as described above will be described with reference to the flowchart of FIG. It should be noted that, in the calculation processing by the CPU, there is no particular distinction between the requested delivery quantity n and the remaining delivery quantity n _1. Therefore, in the description of this flowchart, the same reference numerals are used for each delivery quantity n, n ₁ . It is assumed that the number of items to be delivered is n and that the item is simply treated as the delivery amount n.

First, in step 101, the keyboard 2
Outgoing request data is input from 2 to the inventory management computer 21. That is, the part number of the part X requested to be delivered and the delivery quantity n of the part X requested to be delivered are input to the inventory management computer 21.

Then, in step 102, the inventory management computer 21 determines whether the delivery quantity n of the part X to be delivered is less than or equal to the shelf inventory quantity E. Outgoing quantity n is shelf inventory E
If it is larger than this, it is not possible to issue the part X due to lack of inventory, so the process moves to step 103, and step 103
At, the stock shortage process is performed, and the shipping process is ended.

If the delivery quantity n is less than or equal to the shelf inventory quantity E, it is determined that the requested component X can be delivered, and the step 1
Move to 04. Then, the inventory management computer 21
In step 104, it is determined whether the delivery quantity n is less than the fixed quantity N.

In step 104, if the delivery quantity n is equal to or greater than the fixed quantity N, the process proceeds to step 105, and the inventory management computer 21 determines in step 105 that the storage section 3 storing the fixed quantity N loads W. Search whether or not there is. As a result, when there is the intended storage unit 3, the stock management computer 21 reserves delivery for one storage unit 3 from the searched storage units 3 in step 106. After the delivery is reserved, the inventory management computer 21 proceeds to step 10
In step 7, the fixed quantity number N is subtracted from the discharged quantity n to calculate a new discharged quantity (remaining discharged quantity n ₁ ) n. Next, the inventory management computer 21 performs the processing of steps 104 to 107 again on the delivery quantity n obtained by the calculation,
The delivery reservation of the storage unit 3 in which a fixed number N of loads W are sequentially stored is performed.

In each process of carrying out the delivery allocation, if the delivery quantity n is less than the fixed quantity N in step 104, or if the fixed quantity W of the fixed quantity N cannot be retrieved in step 105. Then, the process proceeds to step 108.

Also, in step 104, if the quantity of delivery n at the time of the delivery request is less than the number of fixed quantity N, the process similarly moves to step 108. In step 108, the inventory management computer 21 determines whether or not there is the storage unit 3 that stores the load W including the same number of parts X as the delivery quantity n. Then, as a result, when there is the target storage unit 3, the stock management computer 21 selects one of the storage units 3 in step 109 and performs delivery reservation. Then, in step 110, the inventory management computer 21 creates shipping operation instruction data for sequentially performing the corresponding normal shipping work in the order in which the shipping allocation is performed based on the shipping allocation performed so far. To do. Then, the inventory management computer 21 outputs the leaving work instruction data to the crane controller 10 to issue a leaving instruction to the stacker crane 5.

On the other hand, if it is determined in step 108 that there is no storage unit 3 that stores the load W having the same number of parts X as the delivery quantity n, in step 111 the inventory management computer 21.
Searches the storage unit 3 that stores the load W of the minimum quantity y.
Then, the inventory management computer 21 proceeds to step 112.
In the above, the minimum quantity y obtained by the above search is the output quantity n
Determine if: If the minimum quantity y is less than or equal to the delivery quantity n, the process proceeds to step 113. If the minimum quantity y is greater than the delivery quantity n, the procedure proceeds to step 115.

In step 113, the stock management computer 21 selects one storage unit 3 from the storage units 3 storing the load W in which the retrieved quantity of the component X is the minimum quantity y, and stores it. The delivery reservation is made for the department 3. Then, the inventory management computer 21 executes steps 111 to 11
The processes up to 4 are sequentially repeated, and the delivery reservation is sequentially performed for the storage unit 3 in which the minimum quantity y of the load W is stored.

Then, at the time of processing of the delivery reservation,
When the minimum quantity y becomes larger than the delivery quantity n in step 112, the process proceeds to step 115. Step 1
At 15, the inventory management computer 21 determines whether or not the delivery quantity n is “0”, and if the delivery quantity n is “0”, it is determined that the delivery allocation work is completed, and step 11
Move to zero. Then, the inventory management computer 21 creates shipping operation instruction data for sequentially performing the corresponding normal shipping work in the order in which the shipping allocation has been performed based on the shipping allocation performed so far, and the stacker crane 5 Issue an issue instruction to.

At step 115, the delivery quantity n is "0".
Otherwise, in step 116, the inventory management computer 21 selects one of the storage parts 3 of the storage parts 3 storing the minimum quantity y of the load W searched in step 111,
Picking allocation is performed for the selected storage unit 3.
Inventory management computer 2 when picking allocation is completed
1 moves to step 110. Then, the inventory management computer 21 issues the shipping work instruction data for performing the normal shipping and the picking shipping in the order in which the shipping allocation and the picking allocation are performed based on the shipping allocation and the picking allocation performed so far. Is created, and the stacker crane 5 is instructed to leave.

Based on the shipping operation instruction data output in this way, the crane controller 10 carries out each corresponding shipping operation in accordance with the order in which the shipping allocation or the picking allocation is made in advance.

Further, the inventory management computer 21 follows the above-mentioned flow chart to determine the load W of one item number requested to be delivered.
When the delivery instruction to the stacker crane 5 is completed, the delivery processing of the load W for the next requested one article number is started according to the above flowchart.

FIG. 2 schematically shows an example of the loads W sequentially delivered for each product number in this way. The alphabets on the loads W indicate the product numbers and the numbers indicate the quantity of the parts X. That is, in FIG. 2, each load W is delivered in the order of the product number A, the product number B, and the product number C in the order in which the delivery request is made. Be issued. Therefore, the loads W are sequentially placed in the pallet 31 in the order in which they are unloaded.
By stacking on top of each other, the loads W are stacked in order from the fixed number N of the loads W. For example, like the load W of the product number C,
The load W for picking work, or the load W with a fraction of 9 or less will be delivered last.

According to this embodiment, the following (a)-
It has the feature (effect) of (d). (A) The cargo W that is unloaded from the automated warehouse 1 is a fixed quantity N of cargo W
It is issued in order from. Therefore, it is possible to reduce the number of shippings as compared with the conventional method based on the "first-in / first-out principle". Also, when stacking loads W on the pallet 31,
It is possible to easily stack the loads W of a fixed number N on the pallet 31 in order, and to load the fractional loads W at the end. Therefore, it is not necessary to stack the stacked loads W again so that the fractional loads W are at the top, and the efficiency of the delivery operation can be improved.

(B) When the delivery quantity n becomes less than the fixed quantity N, the inventory management computer 21 searches the storage section 3 in which the load W consisting of the same number of parts X as the delivery quantity n is stored.
Make a provision. Therefore, the quantity of the parts X requested to be delivered can be delivered easily and reliably, and the efficiency of delivery operation can be further improved. Moreover, since the storage unit 3 that stores the load W made up of the same number of parts X is searched and the delivery allocation is performed, the picking allocation can be suppressed as much as possible, and the load W generated by the picking work for actually taking out the component when the picking is output. Can be prevented.

(C) On the other hand, when the delivery quantity n is less than the fixed quantity N and there is no load W having the same number of parts X as the delivery quantity n, the delivery work is performed from the minimum quantity W. Therefore, the storage section 3 of the automated warehouse 1 can be organized, and the warehousing and warehousing can be efficiently performed. Therefore, it is possible to reduce the number of storage units 3 that store the load W that is less than the fixed number N and to effectively use the shelves 2a and 2b.

(D) Furthermore, when the delivered quantity n becomes less than the minimum quantity y, the picking allocation is performed for the load W having the minimum quantity y, so that the quantity of the delivered parts X with the minimum number of picking times. Can be the requested quantity.

The present invention is not limited to the above-mentioned embodiment, and may be appropriately modified and implemented without departing from the spirit of the invention. (1) In the above-described embodiment, one delivery work instruction data is created for one delivery request data, and normal delivery to the storage unit 3 allocated by, for example, a plurality of delivery allocations and picking allocations is performed based on the delivery operation instruction data. Picking was issued. This is the inventory management computer 2
The item 1 may create one delivery work instruction data for each one delivery reservation or each picking assignment.

(2) In the above embodiment, it may be determined whether or not the delivery quantity n is less than or equal to the fixed quantity N under the condition of step 104 of the flowchart shown in FIG. In this case, even if the delivery quantity n is the same as the fixed quantity N,
Even if the processing moves to step 108, if there is a storage unit 3 that actually stores a fixed number N of loads W, the inventory management computer 21 determines in step 108 that the storage unit 3 stores a fixed number N of loads W. 3 will be selected and allocation will be performed. Therefore, when the delivery quantity n is equal to or larger than the fixed quantity N, the allocation is performed for the storage unit 3 which stores the fixed quantity N of the load W.

(3) In the above embodiment, the present invention is applied to various parts as an article, but it is not limited to parts and may be applied to various food items, clothes, and the like. (4) In the above embodiment, the stacker crane 5 is used as the carrying device. This may be applied to, for example, a transport system that further transports the cargo W unloaded from the automated warehouse 1 by a guided vehicle, and a stacker crane and a guided vehicle may be used as the transporting device.

[0062]

As described above in detail, according to the invention described in claim 1, when the quantity of shipments is reserved in order from the fixed quantity of cargo, and the remaining quantity of shipment is less than the fixed quantity of goods, the remaining quantity of goods is issued. Since the delivery of goods in the same number as the quantity is reserved, the efficiency of delivery work can be improved.

According to the second aspect of the present invention, when there is no storage unit for storing a load having the same number of articles as the remaining delivery quantity, the delivery allocation is made in order from the storage unit for storing the minimum number of articles. Since it is carried out, the goods having a small number of stocks are delivered, and the storage section of the automatic warehouse can be effectively used.
