JP7172584B2 - AUTOMATED WAREHOUSE CONTROL DEVICE AND METHOD FOR BUILDING CONSOLIDATED LOADING MASTER OF AUTOMATED WAREHOUSE - Google Patents

Description

The present disclosure relates to an automated warehouse control device and a consolidation master construction method for an automated warehouse.

An automated warehouse for loading and unloading goods generally has a configuration including racks, cranes, an incoming conveyor, an outgoing conveyor, a picking conveyor, and a carriage.

In the warehousing operation, the cargo is unloaded from a truck or the like, stacked on a pallet, and warehousing information is input from the warehousing terminal. Next, the goods are loaded from the receiving conveyor in units of pallets, moved to racks by the carriage, and stored on the target racks by the crane.

In the unloading operation, the target pallet is taken out from the shelf by a crane according to the unloading instruction, and the pallet is unloaded onto the picking conveyor or the unloading conveyor by the carriage, and the goods corresponding to the unloading instruction are taken out. In the picking conveyor, a worker manually picks up the cargo for the delivery instruction from the pallet (picking delivery). On the unloading conveyor, each pallet is unloaded using a forklift or the like (unit unloading).

In the case of warehousing, cargo is usually "single-loaded" in which only one type of cargo is stowed on a pallet. However, in order to maximize the number of loads on a pallet, there are cases where "mixed loading" is carried out, in which multiple types of loads are mixed and loaded at the operator's discretion. Patent Literatures 1 and 2 have proposed technologies related to mixed loading.

JP-A-7-315520 JP-A-6-211321

However, in the case of "consolidated warehousing" in which pallets that have been "mixed-loaded" (mixed-loaded pallets) are received, there are the following problems.

First, when each shipping instruction in a batch unit is assigned to different cargoes on a mixed pallet, it is necessary to manually pick the specified cargoes from a plurality of pallets. In this case, since the picking operation can only be performed in batch units, it is necessary to take out the mixed pallet from the shelf multiple times. A batch is a unit of delivery instructions such as a truck unit. In addition, there are customer units and delivery route units.

Secondly, recently, there has been an increase in the number of shipments of a wide variety of products in small quantities. For this reason, there is a problem that the number of fractional pallets increases and the shelf storage efficiency decreases. Fractional pallets refer to pallets that are less than the maximum number of items that can be stowed on one pallet.

In view of the above problems, an object of the present disclosure is to provide an automated warehouse control device and a consolidation master construction method for an automated warehouse that can improve the work efficiency of loading and unloading.

A first aspect for achieving the above object is provided with a consolidation master registration unit in which combination patterns of consignments with a high frequency of simultaneous shipment are registered in advance as a consolidation master. Further, at the time of warehousing, the automated warehouse control unit includes a warehousing control unit that refers to the mixed-loading master registration unit and instructs that the cargoes that are highly likely to be shipped simultaneously are mixed on one pallet and stored. is.

In the second mode, the shipping history data is input from the shipping history database section that records the shipping history data, and all the combination patterns for the shipments with a high frequency of simultaneous shipping are generated. The mixed loading master construction method for an automated warehouse includes arranging the generated combination patterns in descending order to build a mixed loading master and registering the mixed loading master in a mixed loading master registration unit.

According to the present disclosure, when a mixed-load pallet is shipped, a plurality of cargoes can be picked at the same time, improving work efficiency.

In addition, it is possible to minimize the number of fractional pallets, and to efficiently carry out the shipping work.

If there is, it is recorded and saved as shipping history data.

The mixed loading master building unit 106 builds a mixed loading master based on the shipping history data from the shipping history database unit 105 . Specifically, the past six months, the past one year, the past three years, or the like is determined and the delivery history is extracted. Alternatively, the delivery history for each season is extracted. Next, from the extracted shipping histories, all combination patterns are generated for loads with a high frequency of simultaneous shipping. The generated combination patterns are arranged in descending order of the number of cases and constructed as a consolidation master. Here, simultaneous shipping means shipping in the same batch process.

The mixed loading master registration unit 107 stores the mixed loading master constructed by the mixed loading master construction unit 106 .

The cargo master registration unit 109 registers, as a cargo master, the shape information (vertical×width×height) of each cargo (case) to be delivered/received. The load master is used when determining whether or not the load A, load B, . . . can be mixed on the pallet.

<Automated warehouse entry/exit processing>
In the above-described automated warehouse 1, loading and unloading is controlled by the following processing. Here, the storage and delivery of cargo A will be described as an example.

When X pieces of goods A are stowed on a pallet by a worker and warehousing information to that effect is input from the warehousing terminal 200 , the warehousing information is output to the automated warehouse control device 100 .

When the pallet loaded with goods A is placed on the carriage 7 via the warehousing conveyor 8, the carriage controller 400 receives the information that the pallet is placed on the carriage 7 and the automated warehouse control device 100. Check for a match with the receipt information from When a match is confirmed, a start signal is output to the carriage 7 . As a result, the carriage 7 on which the pallet is placed travels on the carriage rails 6 . In the embodiment, the carriage 7 runs clockwise.

When the first position sensor 13 detects that the carriage 7 has arrived at the home position HP1, the carriage 7 is temporarily stopped and waits for the next instruction. When the crane-side warehousing conveyors C1, C3, C5, and C7 of the crane-side conveyor 12 are not congested and ready for warehousing, a travel instruction is output from the control unit 15 at the home position HP1 to the carriage controller 400. be done. As a result, the carriage 7 travels to the corresponding warehousing conveyor where there is a row of shelves to be warehousing and stops. Then, it is conveyed by any one of the specified crane-side warehousing conveyors C1, C3, C5, and C7, and is put into the desired rack 2 by the corresponding crane 3.

On the other hand, at the time of warehousing, a process opposite to that at the time of warehousing is executed. When there is a delivery instruction, the pallet on which the goods A are stowed is taken out from the target shelf 2 by the crane 3. The taken out pallets are loaded on the carriage 7 via the crane-side unloading conveyors C2, C4, C6, and C8 and run. When the carriage 7 is detected by the second position sensor 14, it stops temporarily before the home position HP2. The control unit 16 at the home position HP2 checks the availability of the delivery conveyor 9 or the picking conveyor 10, and starts the carriage 7 if there is no congestion.

In the shipping work, in the case of unit shipping in which the cargo A on the pallet is shipped as it is, it is shipped via the shipping conveyor 9 . Also, in the case of picking delivery in which a part of the cargo A on the pallet is picked and delivered, the number of pallets waiting for the picking operation from the first picking conveyor 21 or the second picking conveyor 22 of the picking conveyor 10 is small. is selected. Then, a predetermined number of articles A are picked by the worker via the delivery-side picking conveyor 21A of the first picking conveyor 21 or the delivery-side picking conveyor 22A of the second picking conveyor 22 and delivered. The pallet after being picked is restocked via the restocking side picking conveyor 21B or 22B.

<Consolidated cargo master construction method>
Next, the mixed-loading master construction process executed by the mixed-loading master construction unit 106 will be described with reference to the flowchart of FIG.

The following processing is executed to search for a combination pattern of goods with a high frequency of simultaneous shipping from the shipping history.

When a worker or the like inputs a mixed-loading master construction instruction, the mixed-loading master construction unit 106 first inputs shipping history data from the shipping history database unit 105 (step ST1). As the shipping history data, shipping history for a predetermined period such as six months, one year, three years, or five years in the past, or past shipping history for each season such as spring, summer, autumn, winter, etc. is assumed. .

Next, from the input shipping history data, the combination pattern of the goods shipped at the same time is extracted (step ST2).

After the load combination patterns are extracted, the number of extracted combination patterns is counted (step ST3). For example, the number of cases for all combination patterns of loads is totaled on a daily basis or a batch basis. As a specific example, if there are shipping histories of four types of goods A, B, C, and D, the combination pattern of goods in these shipping histories is as follows.

Combinations for mixed loading of two types of cargo: 6 patterns of (A, B), (A, C), (A, D), (B, C), (B, D), (C, D) 3 Combinations for mixed loading of different types of cargo: There are four patterns: (A, B, C), (A, B, D), (A, C, D), and (B, C, D).

Next, the combination patterns obtained as described above are arranged in descending order of the number of cases and registered as a mixed loading master in the mixed loading master registration unit 107 (step ST4).

For example, in the above example, as a result of tallying the number of cases of each pattern, when two types of cargo are mixed in a predetermined period, (A, B) 1 case, (A, C) 10 cases, (A, D ), 5, and so on. In this case, 10 cases (A, C), 5 cases (A, D), and 1 case (A, B) are arranged in descending order of the number of cases. In this way, a combination pattern of cargoes with a high frequency of simultaneous shipping is extracted from the shipping history and registered in the mixed loading master registration unit 107 as a mixed loading master.

Note that the mixed loading master is configured to be editable. By periodically reviewing and editing combination patterns of cargoes that are highly likely to be shipped simultaneously at the discretion of the manager or the like, it is possible to reconstruct a more convenient consolidated cargo master.

Next, the processing procedure at the time of warehousing will be described with reference to the flowchart shown in FIG.

When pallet-by-pallet information (type, number, pallet No., etc.) related to cargo is input from the warehousing terminal 200 as warehousing information, the warehousing/dispatching control unit 102 determines whether or not mixed loading is possible based on the warehousing information. (step ST11). If mixed loading is possible, the mixed loading master of the mixed loading master registration unit 107 and the cargo master of the loading master registration unit 109 are referred to, and the display unit 108 displays a combination pattern with a high possibility of simultaneous shipping (step ST11 YES). , ST12).

The operator refers to the combination pattern displayed on the display unit 108 with a high possibility of simultaneous delivery, and mixes a plurality of types of cargo on the pallet to generate a mixed pallet. The produced mixed pallet is placed on the carriage 7 via the warehousing conveyor 8 and conveyed. On the other hand, if it is not mixed loading, it is treated as a normal loading, and a single pallet is generated and placed on the carriage 7 via the loading conveyor 8 and transported (step ST11 NO).

When the pallet is completely loaded and the warehousing information is input from the warehousing terminal 200, the warehousing control unit 102 of the automated warehouse control device 100 outputs a warehousing instruction to the control unit 15 of the home position HP1. (Steps ST13 and ST14).

In this way, by stacking cargoes that are highly likely to be shipped simultaneously on one pallet and storing them as a mixed pallet, efficient shipping processing becomes possible.

Next, the effects of the embodiment will be described with reference to FIG.
As described above, when each shipping instruction in batches is assigned to different cargoes on a mixed pallet, it is necessary to manually pick the specified cargoes from a plurality of pallets. In this case, since the picking work can only be done in batch units, conventionally, it is necessary to take out the mixed pallet from the shelf multiple times.

For example, assume cargo A and cargo B that are highly likely to be shipped at the same time. Assume that there are an intra-batch picking process B1 for picking and shipping 10 goods A and an intra-batch picking process B2 for picking and shipping 10 goods B. FIG.

As shown in FIG. 5(A), cargo A and cargo C are mixed on mixed pallet P1, and cargo C and cargo B are mixed on mixed loading pallet P2 as shown in FIG. 5(B). It is assumed that there is In this case, as the intra-batch picking process B1, the mixed pallet P1 is delivered, and after 10 cargoes A are picked, the mixed pallet P1 is restocked. Next, in the intra-batch picking process B2, the mixed pallet P2 is delivered, and after 10 cargoes B are picked, the mixed pallet P2 is restocked. As described above, in the conventional method, the picking process B1 in the batch process for picking 10 loads A from the mixed pallet P1 and the picking process B2 in the batch process for picking 10 loads B from the mixed pallet P2 occur. .

On the other hand, in the method of the embodiment shown in FIG. 5(C), combination patterns of cargoes with a high frequency of simultaneous shipment are registered in advance in the consolidation master register 107 as a consolidation master. Based on this consolidation master, consignments with a high frequency of simultaneous shipment are stacked on consolidation pallets and stored. Specifically, it is assumed that there is a shipping instruction to pick and ship 10 loads A and 10 loads B from a mixed pallet P3 on which loads A and B that are highly likely to be shipped at the same time are stacked. Here, as in the above-described intra-batch picking process B1 and intra-batch picking process B2, when two or more picking instructions are received for the same pallet within the same batch, the picking instructions are simultaneous picking instructions. In this case, by shipping the mixed pallet P3, the worker can pick 10 loads A and 10 loads B at the same time. The mixed pallet P3 after the goods A and B have been picked is restocked.

In this way, when carrying out mixed loading, it is not the mixed loading that maximizes the loading quantity based on the operator's judgment, but rather the mixed loading that is highly likely to be shipped at the same time based on the past shipping history. Simultaneous picking from pallets can be increased. In the case of mixed loading of two types of cargo, two pickings become one, which improves the efficiency of shipping work.

<Consolidated stacking of fractional pallets>
Consolidated stacking processing for fractional pallets will be described with reference to the flowchart of FIG.

First, the warehousing/dispatching control unit 102 refers to the warehousing history data of the warehousing history database unit 105, and extracts fractional pallets from the pallets that have been shipped (step ST21). Next, by referring to the mixed loading master of the mixed loading master register 107 and the cargo master of the loaded master register 109, it is determined whether or not the extracted fractional pallet can be mixed (step ST22).

Next, it is determined whether or not there is a mixed-loadable fractional pallet (step ST23). If there is a mixed-loadable fractional pallet, the crane controller 500 and the crane-side conveyor controller 600 are instructed to take out the corresponding fractional pallet (step ST24).

Then, the shipped fractional pallets are conveyed to the picking conveyor 10, and mixed loading is performed by the operator. When the mixed loading is completed (step ST25 YES), the loading/unloading control unit 102 outputs a mixed pallet re-stocking instruction to the conveyor controller 300 (step ST26).

As a specific example, as shown in FIG. 7, a fractional pallet PA loaded with cargo A and a fractional pallet PC loaded with cargo C are mixed by a worker, and cargo A and cargo C are mixed. A mixed pallet PAC is generated. The generated mixed pallet PAC is restocked on a predetermined shelf 2. - 特許庁

In this way, after the cargo to be mixed is specified, the mixed pallet is made periodically by taking out the fractional pallet of the mixed cargo and re-entering the mixed loading. Therefore, the fraction palette can be reduced. In addition, since the mixed pallet contains loads that can be shipped at the same time, shipping work is made more efficient.

<Other embodiments>
<<Modification 1>>
<Consolidated warehousing processing after receiving inspection>
This is an additional function at the time of receiving inspection. After completing the registration of receiving inspection, the receiving/dispatching control unit 102 refers to the mixed loading master and searches for a combination pattern of inspected loads. The corresponding load combination patterns are displayed on the display unit 108 in descending order of frequency. The worker stacks the goods on the pallet according to the combination pattern of the goods and executes the warehousing operation.

<<Modification 2>>
In order to improve shelf storage efficiency, the loading/unloading control unit 102 refers to the mixed loading master, and displays on the display unit 108 candidate combinations of odd pallets in descending order of frequency of combination patterns of cargo. The manager selects a combination of fractional pallets and issues them. The worker stacks the goods on the pallet according to the combination pattern of the goods and executes the re-stocking operation.

<<Modification 3>>
It is assumed that there is a pallet that will be a fractional pallet after picking at the time of delivery. In this case, if there is a cargo that can be mixed with the fractional pallet after picking at the time of batch unit delivery, the delivery destination of the pallet is changed from delivery to the picking conveyor 10 to delivery to the delivery conveyor 9. - 特許庁Then, the pallets delivered to the delivery conveyor 9 are carried to a cargo handling area (truck berth 11) for picking, and the fractional pallets after picking are used as mixed pallets for re-entry from the delivery conveyor 8.例文帳に追加

Efficient loading and unloading processing can also be achieved by the modifications 1 to 3 described above.
