Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium recording an automatic warehouse entry / exit program for preparing an automatic warehouse entrance / exit plan and an entry / exit control device.

[0002]

2. Description of the Related Art Various technologies have been developed to improve the efficiency of loading and unloading operations in an automatic warehouse equipped with a stacker crane.

In general, if the loading and unloading operations are performed alternately as much as possible, the time during which the stacker crane is running in an empty state is reduced, which is effective for improving the loading and unloading work efficiency. You can say that. The following two methods are known for creating an entry / exit plan by combining an entry instruction and an exit instruction for the purpose of improving the efficiency of entry / exit work.

[0004] One of them is that one unit of the loading / unloading operation of the stacker crane is constituted by a cycle in which a loading / unloading operation from a certain loading / unloading port is performed following a loading / unloading operation to a certain loading / unloading port. This is a method of avoiding the occurrence of a state in which the stacker crane moves with an empty load during the operation (Japanese Patent Laid-Open No. 5-58406).

On the other hand, when the number of incoming and outgoing instructions waiting to be processed is less than a certain number, a single incoming or outgoing work is executed in the order in which the instructions are given, and the number becomes more than a certain number. In such a case, the incoming / outgoing instructions waiting for processing are rearranged so that the traveling distance of the stacker crane is minimized (Japanese Patent Laid-Open No. 9-12112).

[0006]

However, in the method described in Japanese Patent Application Laid-Open No. 5-58406, since the entry / exit instruction which is in a process waiting state is not executed until a set of the entry instruction and the exit instruction is created, the group is not executed. Until the entry instruction or the exit instruction is given, the state of waiting for processing is continued, and there is a possibility that the work may not be performed at an appropriate timing.

In the method described in Japanese Patent Application Laid-Open No. 9-12112, it is effective to improve the efficiency of the loading / unloading operation by alternately executing the loading / unloading operation if possible, if possible. Regardless, when the number of incoming and outgoing instructions waiting for processing is less than a certain number, this efficient method is not applied.

On the other hand, in the method described in Japanese Patent Application Laid-Open No. 9-12112, rearranging of the entry and exit instructions for the purpose of efficiency is performed, but when the rearrangement is executed without any special restriction. For example, there is a possibility that some of the goods to be transported on the same truck may be mixed with those to be transported on other trucks. In some cases, it may be difficult to improve the efficiency of the work when applying it to actual work, such as necessity of replacement.

Originally, an entry / exit instruction given earlier in time is expected to complete the entry / exit work early, and the work order is changed in order to increase the work efficiency of the automatic warehouse. This means that the quality of service of the entire warehousing operation such as replacement of the garage truck and extension of the waiting time of the garage truck is reduced.

[0010] The present invention has been made in view of such circumstances, and it is possible to improve the efficiency of the warehousing operation without changing the order of the given warehousing and warehousing instructions. It is an object of the present invention to provide a recording medium and an entry / exit control device which record an entry / exit program of an automatic warehouse which does not wake up and which is highly adaptable to emergency entry / exit.

[0011]

FIG. 2 is a diagram showing the configuration of the storage 4 device.

The storage 4 is provided with a pair of storage shelves 4a and 4b having a plurality of storage sections 6, and each of the storage shelves 4a and 4b
The rails 7 are laid between 4b. This rail 7
A stacker crane 8 is installed on the upper side, and travels back and forth on the rail 7 to take out and store products stored in the storage section 6 at a predetermined position.

FIG. 3 is a block diagram showing a first embodiment of an automatic warehouse entry / exit system to which the present invention is applied.

Here, the configuration of the automatic warehouse to be managed is the same as the configuration shown in FIG. 1, and therefore, the same portions are denoted by the same reference numerals and description thereof will be omitted.

This entry / exit system is an entry / exit controller 1
1. It comprises an automatic warehouse 12 to be managed by the entry / exit control device 11 and a host processing unit 13 for instructing entry / exit information including the entry / exit product name and the quantity thereof.

The input / output control unit 11 performs input and output of various information between the automatic warehouse 12 and the high-level processing device 13, and is required based on input / output instructions from the high-level processing device 13. Receiving / instruction receiving unit 15 for performing various preparations, a tracking processing unit 16 for tracking the transportation status of goods in the automatic warehouse, an in / out plan creating unit 17 for creating an in / out plan based on the in / out instruction, a storage The storage control unit 18 controls the stacker crane 8 for the loading / unloading operation of No. 4 and a storage unit 20 storing data necessary for the operation of each unit.

The warehouse control unit 18 is composed of a warehouse control unit 8a for controlling the warehouse operation to the warehouse 4 and a warehouse control unit 8b for controlling the warehouse operation from the warehouse 4.

The storage unit 20 stores the stacker crane 8
An entry / exit schedule data memory 20a for storing data relating to each entry / exit operation, a tracking data memory 20b for storing the transportation status of goods in the automatic warehouse 12, and reference data to be referred to when creating an entry / exit plan. An entry / exit reference data memory 20c is provided.

Next, the operation of the entry and exit control device 11 configured as described above will be described.

FIG. 4 is a flowchart showing the processing procedure of the entry / exit instruction receiving unit 15.

When the truck carrying the goods arrives at the automatic warehouse 12, the name and quantity of the goods to be carried into the automatic warehouse 12 are determined. The host processor 13 determines the positions of the storage shelves for storing these products, arranges them in the order of storage, and transmits them to the storage and retrieval controller 11 as storage reception information (S1).

When there is a transmission from the host processor 13, the entry / exit instruction receiving unit 15 is activated in the entry / exit control device 11, and
The storage reception information is compiled for each stacker crane 8 in charge of storage (S2).

FIG. 5 is a diagram showing the configuration of the storage work queue 21 for each stacker crane 8.

The stocking work queue 21 has an unloaded area 22 indicating that the goods are transported to the automatic warehouse and are loaded from the goods loading slot 1a, and a product loaded in the goods loading slot 1a.
The storage area 23 is provided to indicate that the apparatus is in a state of being put in from a and waiting for storage at a storage shelf entrance on the receiving aisle conveyor 3a.

In addition to the identification data such as the product name, each of the data includes a status code indicating the current status, "not yet loaded", which is a status before the product is loaded from the product loading slot 1a, and a transport route. "Conveying" which is in a state of being stored, and "Arrived" which is in a state of waiting for storage at a storage shelf entrance on the receiving aisle conveyor 3a.

The entry / exit acceptance instruction unit 15 searches the entry / exit schedule data memory 20a and finds the corresponding stacker crane 8
Each storage operation queue 21 is extracted, and a data code arranged based on the storage reception information is added with a status code of "not input" and stored in the non-input area 22 (S3).

Next, when the truck carrying the goods arrives at the automatic warehouse, the name and quantity of the goods to be paid out of the warehouse are determined. The host processing device 13 specifies the positions of the storage shelves where these products are stored, arranges them in the order of retrieval, and transmits them to the entry / exit control device 11 as retrieval acceptance information (S
4).

When there is a transmission from the host processor 13, the entry / exit instruction receiving unit 15 is activated in the entry / exit control device 11, and
The delivery reception information is compiled for each stacker crane 8 that is in charge of payout (S5).

FIG. 6 is a diagram showing the configuration of the unloading work queue 25 for each stacker crane 8.

In the delivery work queue 25, the product name, the storage shelf position,
Data in which an identification code or the like for specifying a leaving instruction is stored is stored.

The entry / exit instruction receiving unit 15 searches the entry / exit schedule data memory 20a and finds the corresponding stacker crane 8
The retrieval queue 25 for each retrieval work is extracted, and the data arranged based on the retrieval reception information is stored (S6).

When the above-described storage and retrieval processing is completed, the retrieval and preparation plan creation unit 17 is started to prepare a retrieval and retrieval work plan (S7).

FIG. 7 is a flowchart showing the processing procedure of the tracking processing unit 16.

When the incoming goods are introduced from the goods input port 1a, when the incoming goods are on standby on the receiving aisle conveyor 3a, and when the stacker crane 8 is at the origin position (the stacker crane 8 takes out the goods from the aisle conveyor). (Initial standby position), a signal is input from the automatic warehouse to the entry / exit control device 11 at each of the following timings. In the entry / exit controller 11, the input / output data processing unit 14 receives these signals and activates the tracking processing unit 16.

The tracking processing section 16 identifies the input signal and performs processing according to the signal (S10).

First, when the product is started when the goods to be stored are put in from the goods slot 1a (S11), it is specified which of the goods to be stored is put in. Although there are various methods for this method, the present system employs a method of reading and specifying a barcode attached to a product.

If the product can be specified, the stacker crane 8 to be stored can also be specified.
0a is retrieved to extract the corresponding warehousing work queue 21, the data relating to the product described in the unloaded area 22 is taken out, the status code is changed to "transporting", and the data is stored in the loading area 23. (S
12).

Next, the estimated arrival time is calculated. Here, the estimated arrival time means that this product is received by the aisle conveyor 3a.
This is the time when the upper storage shelf doorway enters the standby state for storage. The tracking processing unit 16 searches the entry / exit reference data memory 20c to extract the “required time for transportation” stored for each stacker crane 8, and adds this time to the insertion time of the product to obtain the expected arrival time. Is calculated (S13).

Here, in the present system, the required transfer time uses the actual value up to now. Although the automatic warehouse functions for 24 hours, the operation rate of the equipment during that time is not constant, and usually, the warehousing and warehousing are concentrated at a predetermined time and tend to have a high operation rate. Therefore, a day is divided into a plurality of time zones, and the actual value of the required transport time in the time zone is stored, and the accurate required transport time can be easily obtained by using the value. Note that the required transfer time may be determined by, for example, the transfer route 2 without using the above-described actual value.
May be calculated from the transfer speed and the transfer distance.

After the above processing, the entry / exit plan creation unit 17 is started to create an entry / exit work plan (S14).

When the incoming goods are in the standby state at the storage shelf entrance on the receiving aisle conveyor 3a (S15), the goods in the standby state are specified in the manner described above, and the receiving work queue 21 is searched. The status code of the product is changed to "arrival" (S16).

At this time, since the required transfer time is determined, the actual "required transfer time" is stored in the entry / exit reference data memory 20c, and an entry / exit plan creation unit 17 is prepared to create an entry / exit work plan. Is started (S17).

When the stacker crane 8 is started when it returns to the home position (S18), the stacker crane has completed a series of operations and is in a state of waiting for an instruction for the next operation.
Therefore, the entry / exit plan creation unit 17 is started to create an entry / exit work to be performed next (S19).

FIGS. 8 and 9 are flowcharts illustrating the processing procedure of the entry / exit plan creator 17.

The entry / exit plan creator 17 is activated at each of the above-described timings to create an entry / exit plan. This plan is not a long-term plan, but executes the next operation when the operation being executed at a certain point in time is completed. To decide.

First, the receiving work queue 21 is empty (S3
0), and when the outgoing work queue 25 is empty (S31), there is no scheduled work, so the apparatus waits until a new in / out instruction is issued (S32).

When the receiving work queue 21 is empty (S30),
In addition, when there is a product scheduled to be delivered in the delivery work queue 25 (S31), the delivery control unit 18b is started by designating the shelf position of the product to perform the delivery work independently (S3).
3). The retrieval control unit 18b controls the corresponding stacker crane to retrieve the products stored at the designated position on the shelf.

There is a product to be stored in the storage work queue 21 (S30), and the storage work queue 25 is empty (S3).
In the case of 4), the status code of the first product in the warehousing work queue 21 is checked (S35). Status code "Arrived"
In the case of (S36), this product is already in a state where it can be stored, so a plan for the storage operation is examined.

First, a scheduled ending time T1 of the storage operation when the stacker crane 8 performs the storage operation alone is calculated (S37). The scheduled ending time T1 of the storage operation can be calculated from the required time of the storage operation and the current time. The time required for the warehousing operation is obtained by calculation from the time required for the stacker crane 8 to reciprocate between the shelf positions where the products are stored and the time required for taking out the products, and the traveling speed of each stacker crane 8 used at that time. The specifications such as the distance between the shelf position and the origin position are stored in the entry / exit reference data memory 20c.

Subsequently, a scheduled outgoing work instruction time T2 at which the next outgoing work instruction is input is obtained (S38). Similar to the above-described calculation of the required transportation time, the next retrieval instruction scheduled time T2 is also calculated using the actual value of the interval time at which the retrieval instruction is input in the time period by dividing one day into a plurality of time zones. . The interval time at which the leaving instruction is input is stored in the entering / leaving reference data memory 20c.

The estimated incoming work end time T1 and the expected outgoing work instruction time T2 obtained as described above are compared (S).
39).

If the scheduled ending time T1 of the warehousing work is earlier than the scheduled time T2 of instructing the warehousing work, the warehousing operation is performed by itself, and a shelf position where goods are to be stored is designated and the warehousing control unit 18a is started (S40). ). The storage control unit 18a controls the corresponding stacker crane 8 to store goods in the receiving aisle conveyor 3a at a designated shelf position.

If the scheduled ending time T1 of the warehousing work is later than the scheduled time T2 of the outgoing work instruction, the process waits until a next outgoing work instruction is input (S41).

There is an article to be received in the receiving work queue 21 (S30), and the discharging work queue 25 is empty (S3).
In the case of 4), if the status code of the first product in the receiving work queue 21 is “transporting” or “not loaded”, the process waits until the status code of this product changes to “arrival” (S42). .

If there is a product to be received in the receiving work queue 21 (S30) and there is a product to be released in the leaving work queue 25 (S34), the status code of the first product in the receiving work queue 21 is checked. (S43). If the status code is "arrival" (S44), since both the warehousing work and the warehousing work are executable, a set of work plans for performing the warehousing work and the warehousing work in this order is created (S45). ).

In the case where there is a product to be received in the receiving work queue 21 (S30) and there is a product to be released in the receiving work queue 25 (S34), the status code of the first product in the receiving work queue 21 is In the case of “transporting”, consider a plan for the outgoing work.

First, a leaving operation end time T3 when the stacker crane 8 performs the leaving operation alone is calculated (S3).
46). The leaving work end time T3 can be calculated from the leaving work required time and the current time. The time required for the unloading operation is obtained by calculation from the round trip time to the shelf position where the stacker crane 8 intends to pay out the goods and the time required for paying out the goods, and the traveling speed of each stacker crane 8 used at that time, Specifications such as the distance between the shelf position and the origin position are stored in the entry / exit reference data memory 20c.

Subsequently, the estimated arrival time T4 of the product is obtained (S47). This estimated arrival time T4 has already been calculated and stored in the warehousing work queue 21 as data of the corresponding product.

The leaving work end time T3 obtained as described above is compared with the estimated arrival time T4 (S48).

The unloading work end time T3 is the expected arrival time T4
If it is earlier, in order to carry out the leaving work alone, the delivery control unit 18b is activated by designating the shelf position where the product is stored (S49). The retrieval control unit 18b controls the corresponding stacker crane 8 to retrieve a product stored at a designated position on the shelf.

The unloading work end time T3 is the expected arrival time T4
If it is later, the process waits until the status code of the product changes to "arrival" (S50).

According to the above-described processing procedure, a product entry / exit plan is created and the process is executed.

The system described in this embodiment is
The program can be realized by reading the program stored in the recording medium into a computer. The functions of the entry / exit instruction receiving unit 15, tracking processing unit 16, entry / exit plan creation unit 17, and warehouse control unit 18 are provided by the present system. It is recorded on an attached (not shown) recording medium.

[0073]

As described above, according to the present invention, the alternate operation of the warehousing operation and the warehousing operation can be performed as much as possible, so that the efficiency of the warehousing operation can be improved.

Further, since a plan is prepared in which the given order of the incoming and outgoing work is not changed as much as possible, the quality of the service is hardly deteriorated.

Further, since an entry / exit plan is created for each time, it is not necessary to largely change the plan for emergency entry / exit.
