[0002]

2. Description of the Related Art Conventionally, there is a parts automatic warehouse system which automatically manages warehousing and storage of a warehouse for storing parts mounted on a printed circuit board. In such an automatic parts warehouse system, for example, among a plurality of shipping plans corresponding to a plurality of printed circuit boards, plans of common parts having a high shipping frequency are put together to collectively retrieve the same common parts. The delivery plan for one day has been created by organizing a plan for the individual picking work in which a part for each individual plan is extracted from the plans for the parts that are not common parts.

The information processing apparatus for controlling this system conveys the parts to be delivered from the automatic warehouse to the work station for picking, according to the produced delivery plan.
The worker at each station takes out a specified number of parts from the delivered parts to be delivered, and after all the aggregate picking work and individual picking work for one day are completed,
A synchronization work was performed in which the parts picked up by the aggregate picking work and the individual picking work were put together for each printed circuit board. In addition, during such work, if there is a significant difference between the progress of the aggregate picking work and the individual picking work, the worker at the work station that can support is delayed by the worker's judgment. Was.

[0004]

As described above, in the conventional automatic parts warehouse system, the synchronization for supplying the parts to the production line or the like after the completion of the aggregate picking work and the individual picking work for one day are completed. However, since the production work is carried out, there is a problem that only a batch supply method for supplying one day in a lump can be taken, and a real-time supply method for supplying a detailed response to the demands of the production line cannot be realized. Further, since the worker determines the progress status of the work after finishing his / her own work and supports the delayed work, the burden on the worker is large and the work efficiency is low. The present invention has been made to solve the above problems, and a first object thereof is to provide an automatic parts warehouse system capable of realizing real-time supply to a production line or the like. A second object is to provide an automatic parts warehouse system that can reduce the burden on the operator.

1 is a block diagram of an automatic parts warehouse system showing an embodiment of the present invention. Reference numeral 1 denotes a parts master information storage device that stores identification information indicating whether or not the parts are common parts for all the parts stored in the automated warehouse. Reference numeral 2 denotes an information processing device that manages a warehouse. For example, a plurality of shipping plans corresponding to each printed circuit board are classified into a shipping group that is a planned amount that can be worked within a predetermined time, and an integrated picking plan is created for each shipping group. An individual picking plan is organized, a shipping work instruction indicating the work content to be performed based on the created plan is output to the terminal device of the work station described later, and the control information corresponding to this data is output to the storage / removal device and the storage device described later. Output to the conveyor.

Further, 3 is a shelf of an automated warehouse that stores parts, and 4 is a parts storage bucket 7 in which parts to be delivered are stored.
a to 7c are conveyed to the corresponding work station according to the control information, 5a to 5c are work stations,
6a to 6c are installed in the work stations 5a to 5c,
It is a terminal device for displaying a leaving work instruction output from the information processing device 2 to a worker of each station.

The transfer device is composed of a take-out / storage device (not shown) such as a forklift or a crane for transferring the component storage buckets 7a to 7c from the shelf 3 according to the control information, and a conveyor 4.

Next, the operation of such an automatic parts warehouse system will be described. First, the information processing device 2 creates a shipping plan for one day as follows. FIG. 2 is a flow chart for explaining the operation of the information processing device 2 at the time of creating a shipping plan.

The shipping plan is a collection of data indicating a shipping schedule for each part, and this data includes an identification code of a shipping target part, a product name, a shipping quantity, a part group name to which this part belongs, and the like. A parts group is a collection of parts that are collectively supplied to a delivery destination such as a production line.
All components mounted on one printed circuit board form a component group. Therefore, in this case, the component group name is the board name.

First, the information processing device 2 checks whether there is a carry-out plan for the carry-over from the previous day (step 10
0), if the previous sunrise storage plan remains and the determination is Yes, the priority of this delivery plan is increased (step 10).
1). Then, it is checked whether or not there is an urgent shipping plan associated with the urgent production instruction (step 102). If there is an urgent shipping plan and the determination is Yes, the priority of this shipping plan is increased (step 103).

After the priority order of the work is determined as described above, the one-day storage plan is classified into the output group representing the planned work amount within a predetermined time of, for example, one hour according to the priority order (step 104). . By the way, as the parts stored in the automated warehouse, there are common parts having a high delivery frequency and parts having a low delivery frequency.

The component master information storage device 1 stores identification information indicating whether or not it is a common component for all components,
The information processing device 2 refers to the storage device 1 and determines whether each part in the created shipping group is a common part (step 105). Then, in the case of a component registered as a common component, the delivery quantity indicated by the plan of this common component is added within the same delivery group to make the delivery plan 1
And integrate them into an integrated picking plan (step 106).

If the parts are not common parts, the delivery plan of this part is incorporated into the individual picking plan as it is (step 107). After performing the processing of steps 105 to 107 for all the parts within the same shipping group, it is determined whether or not the organization has been completed for all shipping groups (step 108). Then, when it is not completed, the processes of steps 105 to 108 are repeated.

FIG. 3 is a diagram showing an example of creating a shipping plan as described above. 10a to 10c are shipping groups, 11a,
12a have group names “PWB1” and “PWB”, respectively.
2 ”is a delivery plan for a parts group, 13a is a collective picking plan, and 14a is an individual picking plan. FIG. 3A illustrates a state in which the one-day storage plan is classified into the delivery groups 10a to 10c in step 104.

By the way, within the above-mentioned predetermined time, for example, a picking operation of a component group corresponding to a plurality of printed circuit boards may be performed, so that one shipping group includes shipping plans for a plurality of component groups. Therefore, the shipping group 10a in FIG. 3A also includes two parts groups 11a and 12a.

Looking at the delivery plan 11a for the part group with the group name "PWB1", it can be seen that the delivery quantity of the parts with the identification code "IC1" and the part name "IC" is 10, for example. Similarly, the group name is "P
Looking at the delivery plan 12a related to the component group "WB2", the delivery quantity of the component having the identification code "R1" and the component name "R" is 100 pieces.

In FIG. 3B, in steps 105 to 107, shipping plans 11a and 12 in the shipping group 10a.
a is an integrated picking plan 13a and an individual picking plan 1
It shows a state of being reorganized into 4a. Now, storage device 1
Assuming that "TR1" and "R1" are registered as common parts in the information processing device 2,
"TR1" and "R1" in a are recognized as common parts, and these are incorporated into the aggregate picking plan 13a.

At this time, the parts "TR1" and "R1" are
Plan 1 as it is included in both shipping plans 11a and 12a
By adding the quantities of 1a and 12a and combining them into one, the delivery quantity of the part "TR1" is 90 pieces and "R1" is 2 pieces.
It will be 00. The data added after the delivery quantity is data for sorting work described later. For example, for the part “TR1”, “PWB150”,
Data "PWB240" is added. This indicates that the part “TR1” is sorted into 50 parts for the part group with the group name “PWB1” and 40 parts for the part group with the group name “PWB2”.

In addition, "TR1" and "R" which are not common parts
For parts other than 1 ”, the plan of each part is incorporated into the individual picking plan as it is, so that
The individual picking plan 14a like this is created. As described above, the preparation of the shipping plan for one day is completed.

Next, the operation during the actual shipping operation will be described. FIG. 4 is a flow chart for explaining the operation at the time of leaving work. Each worker of the work stations 5a to 5c selects a work to be carried out at his / her station when starting the work, that is, an integrated picking work or an individual picking work, and inputs the selected contents into the terminal devices 6a to 6c (not shown). Input to each device (step 200).

As a result, the work mode information indicating the selected work is output from the terminal devices 6a to 6c, and the information processing device 2 sets the work mode of each station according to this information. Here, the work mode of the work station 5a is set to the aggregate picking work, and the station 5
It is assumed that the work modes b and 5c are set to the individual picking work.

Next, the information processing device 2 outputs the aggregate picking plan 13a of the first shipping group 10a to the terminal device 6a of the station 5a whose work mode is aggregate picking, and performs control corresponding to this aggregate picking plan. The information is output to the take-out / storage device of the automatic warehouse and the conveyor 4 (step 201). At this time, the information processing device 2
Outputs the aggregate picking plan 13a in component units.
Therefore, first, a shipping operation instruction for the component “TR1” is output.

An output device (not shown) of the terminal device 6a displays the leaving work instruction output from the information processing device 2 and prints this data on a slip. In the aggregate picking plan, a plurality of shipping plans are grouped together and sorting is performed after picking, so that a slip is printed for each parts group.

For example, for the part "TR1", the identification code "TR1", the part name "TR", the classification data "PWB150", and the identification code "TR"
1 ”, part name“ TR ”, and sorting data is“ PWB2 4
The slip “0” will be printed.

On the other hand, the take-out / storing device of the automatic warehouse takes out the parts storage bucket storing the corresponding parts from the shelf 3 according to the control information and places them on the conveyor 4. And
The conveyor 4 conveys this bucket to the corresponding work station according to the control information. Thus, the part "TR1"
Departure work instruction is displayed and the slip is printed, and the part "T
The bucket 7b storing "R1" is conveyed to the station 5a as shown in FIG.

The worker at the work station 5a looks at the shipping operation instruction displayed on the terminal device 6a, takes out the parts from the bucket 7b by the specified shipping quantity, and when the work is completed, the operator operates the input device of the terminal device 6a. Operate and enter the end of work. As a result, the performance information is reported from the terminal device 6a to the information processing device 2. Further, the other worker sorts the extracted parts according to the sorting data in the shipping work instruction, and attaches a slip to each sorted part.

For example, for the part "TR1", 50
It is divided into 40 pieces and 40 pieces, and a slip in which the part group name is printed as "PWB1" is attached to 50 parts.
A slip having a group name "PWB2" is attached to 0 parts. In this way, the parts are picked up and sorted in the aggregate picking work. When the worker returns the bucket 7b to the conveyor 4, the bucket 7b is moved by the conveyor 4 and the take-out / storing device.
It is returned to the original position of the shelf 3.

Next, when the information processing device 2 receives the performance information from the terminal device 6a, all the shipping plans (here, the integrated picking plan) for the current shipping group 10a according to the work mode of the station 5a are completed. It is determined whether or not (step 202). In this embodiment, since the component “R1” remains, the process returns to step 201,
Similar to the above, the collective picking operation for the component “R1” is performed. Thus, such steps 201, 202
The operation of is repeated until the aggregate picking plan of the current issue group is completed.

Although aggregate picking has been described above, the same operation is performed in parallel with aggregate picking for the work stations 5b and 5c that have selected individual picking. That is, the information processing device 2 outputs the individual picking plan 14a of the shipping group 10a to the terminal devices 6b and 6c, and outputs the control information corresponding to the output individual picking plan to the extraction / storage device and the conveyor 4 (step 201). ).

Now, in the individual picking plan, since the work stations are assigned for each component group, for example, the station 5b is assigned for the component group whose group name is "PWB1" and the station 5c is "PWB2".
If it is assigned to a component group called
The leaving work instruction for the component "IC1" is output to b, and the leaving work instruction for the component "R2" is output to the terminal device 6c. Then, the terminal devices 6b and 6c display the leaving work instruction and print it on the slip as in the above.

Further, according to the above control information, the component "IC
The bucket storing "1" is transported to the station 5b, and the bucket storing the component "R2" is transported to the station 5c. Each of the workers at the stations 5b and 5c takes out a specified quantity of parts from the bucket by looking at the shipping work instruction, attaches a slip to the taken out parts, and after the work is completed, finishes the work from the input devices of the terminal devices 6b and 6c Enter. As a result, the terminal device 6b, 6c reports the performance information to the information processing device 2.

When the information processing device 2 receives the performance information from the terminal devices 6b and 6c, all the shipping plans (here, individual picking plans) according to the work modes of the stations 5b and 5c are all related to the current shipping group 10a. It is determined whether or not the process is completed (step 202), and if not completed, the process returns to step 201. In this way, the operations of steps 201 and 202 are repeated until the individual picking plan of the current shipping group is completed.

Further, during the above work, when a situation occurs in which either one of the aggregate picking plan or the individual picking plan of the current issue group is finished, and the other is not finished, it is not finished. In parallel with the station that is performing the work, the following support work is performed by the station that has completed and completed one work. For example, when the aggregate picking plan 13a is completed and the determination in step 202 is Yes, the information processing device 2
Determines whether or not another shipping plan in the current shipping group 10a, that is, the individual picking plan 14a is completed (step 203).

If not completed, the station 5 which has completed the integrated picking plan 13a and completed
The work mode of “a” is temporarily changed to the support mode, the unfinished individual picking plan 14a in the shipping group 10a is output to the terminal device 6a of the station 5a, and the control information corresponding to the output individual picking plan is extracted. The data is output to the storage device and the conveyor 4 (step 204). As a result, the same individual picking work as described above is performed at the station 5a, and the worker is allowed to perform the terminal device 6a after the work is completed.
Input the end of work from the input device.

Next, when the information processing device 2 receives the performance information from the terminal device 6a, the process returns to step 203 and again the individual picking plan 14a of the current shipping group 10a.
Determines whether or not Thus, step 2
The operations of 03 and 204 are repeated until the shipping plan under support in the current shipping group ends. Even when the individual picking plan is finished and the aggregate picking plan is not finished, the information processing device 2 performs the same processing, and the same support work is performed by the work stations 5b and 5c where the individual picking work is finished. Is done.

Then, in step 203, the determination is Y.
When es, that is, when all the shipping plans of the current shipping group 10a are completed, the information processing device 2 outputs a synchronization instruction signal to the terminal devices 6a to 6c of each station (step 205). Then, the output devices of the terminal devices 6a to 6c, in response to the synchronization instruction signal, instruct the start of the synchronization work for grouping the parts extracted by the aggregate picking work and the individual picking work into each parts group. Display.

A worker in charge of the synchronization work of the stations 5a to 5c (a worker different from the above picking work) is
The synchronization work is performed according to the slip attached to the taken out parts, and after the work is finished, the input device is operated to input the work finish. For example, with respect to the delivery group 10a, there are a part group with a group name of "PWB1" and a part group with a group name of "PWB2". Therefore, "PWB1" is written on the slip from the aggregate picked parts and the individual picked parts. The synchronization work is completed by grouping together the components described above and the components described in the slip as “PWB2”.

On the other hand, the information processing device 2 executes step 205.
In the case where there is a work station that has been temporarily put into the support mode by the support work described above after outputting the synchronization instruction signal in step 1, the work mode is returned to the original mode (step 206),
It is determined whether or not the created shipping plan includes the next shipping group (step 207).

In this embodiment, since the group 10b exists as the next shipping group, the process returns to step 201 and the same operation as the shipping group 10a is performed. In this way, the same operation is repeated for each shipping group until the work of all shipping groups is completed.

As described above, since the picking work and the synchronizing work can be performed for each shipping group, real-time supply to the shipping destination can be realized. In addition, the worker who performs the picking work will perform the work of the next issuing group when one issuing group ends, and the worker who performs the synchronization work in parallel performs the synchronizing work of the finished issuing group, so the picking The work and the synchronization work can be performed in parallel, and the work efficiency can be improved as compared with the conventional case where the synchronization work is performed after all the picking works for one day are completed.

In the present embodiment, the information processing device 2 is set to 1
We have created a day-to-day shipping plan and started the work, but it is also possible to incorporate a new shipping plan and change the plan midway due to an urgent demand from the production line, etc., thereby realizing more detailed supply. It goes without saying that you can do it.

[0046]

According to the present invention, the information processing apparatus classifies the shipping plans into shipping groups and outputs an instruction signal when all shipping operations in the current shipping group are completed,
In response to this instruction signal, the terminal device displays the data for instructing the worker to start the synchronization work, so that the picking work and the synchronization work can be performed for each delivery group, so that the production line, etc. Real-time supply can be realized by supplying finely to the destination.

Further, when either the aggregate picking plan or the individual picking plan of the current shipping group is finished and the other is not finished, mutual support of the aggregate picking work and the individual picking work is instructed by the instruction of the information processing device. Since it is performed, it is not necessary for the worker to judge the progress status of the work, and the work efficiency can be improved by reducing the burden on the worker.
