  In the section management record of the section in which the parts are allocated and the storage box 2 is stored, the corresponding data is written in the above fields, but the parts are not allocated and the storage box is stored. In a partition management record of an empty partition in which 2 is not stored, a symbol “-” indicating “free” is written in each column other than the partition address column 361.

The data example of FIG. 7 shows the usage state of the following sections.
(1) Delivered to lot “A-1” (line 1) and block “B-3” (line 7) from the same “maker B” in separate lots (“Lxx1” and “Lxx2”) The same parts (product name code “P001”) are stored. Further, the remaining quantity (46) of the section “A-1” whose storage deadline (20xx.08.31) arrives earlier is the same as that of the section “B-3” whose storage deadline (20xx.11.30) arrives late. Since it exceeds the remaining quantity (12 pieces), it can be seen that the first-in first-out process of parts is not performed correctly.
(2) The section “A-2” (second line) and the section “B-1” (fifth line) are “vacant”.
(3) In the section “A-3” (line 3), 125 parts corresponding to the actual product slip number “Sxx3” are stored.
(4) In the section “A-4” (line 4), 51 parts corresponding to the actual product slip number “Sxx1” are stored.
(5) In the section “B-2” (line 6), 50 parts corresponding to the actual product slip number “Sxx5” are stored.

  The shelf allocation history table 37 is a table for recording, in a time series, the history of component addition / deallocation to each section of the component shelf 1 as shown in FIG. The shelf allocation history table 37 includes a date / time column 371, a section address column 372, a current product slip number column 373, a product name code column 374, a manufacturer name column 375, a lot number column 376, and a receipt quantity column 377. A row constitutes a shelf allocation history record that represents information about the addition / deletion of part allocation once. The date / time column 371 of each shelf allocation history record shows the date / time when the part assignment was added or released, the partition address column 372 shows the target partition address, and the actual product slip number column 373 shows the assignment. The item number code corresponding to the selected part, the part name code column 374, the part name code of the part, the manufacturer name field 375 the name of the manufacturer that manufactured the part, and the lot number field 376 purchased the part. The lot number assigned at that time is stored in the storage quantity column 377, respectively.

  In addition, when the allocation of the parts to the sections is added, the actual product slip IC tag number of the actual product slip attached to the corresponding supplement storage box 2a (FIG. 1) and the supplement storage box 2a are stored. The section IC tag number of the section thus read is read and transmitted to the database server 30. The database server 30 obtains the corresponding section address from the section IC tag number transmitted by referring to a correspondence table (not shown) and the like, obtains the actual product slip number from the transmitted actual product IC tag number, and the actual product slip number. The necessary information is obtained from the corresponding actual product record record by searching the actual product form management table 35 using as a key, and the shelf allocation history record is generated and added to the head of the shelf allocation history table 37 and recorded.

  On the other hand, when the part assignment is canceled, the symbol “-” indicating that the assignment has been released is written in the actual product slip number field 373 by the same process, and the receipt quantity field 377 shows the current state. The remaining quantity of the part (usually 0) is written in parentheses.

The data example in FIG. 8 shows the recorded contents (dates from the bottom in the order from the oldest) when the assignment is added and deallocated in the following order.
...
(1) The assignment of parts to the section “B-3” has been released.
(2) The assignment of parts corresponding to the actual product slip number “Sxx2” is added to the section “A-1”.
(3) The assignment of parts to the section “A-2” has been released.
(4) The assignment of the part corresponding to the actual item number “Sxx4” is added to the section “B-3”.
(5) The assignment of the part corresponding to the actual item number “...” Is added to the section “D-5”.

  In this example, it is delivered from the same “Manufacturer B” in different lots (“Lxx1” and “Lxx2”) from the two rows enclosed in the frame (corresponding to (2) and (4) above). It can be seen that the same parts (product name code “P001”) are assigned to the sections “A-1” and “B-3”, respectively.

  The picking work history table 38 is a table for recording the history of picking work performed by the picking worker in time series, as shown in FIG. The picking work history table 38 includes a date / time field 381, a section address field 382, a current product slip number field 383, a product name code field 384, a manufacturer name field 385, a lot number field 386, and a picking quantity field 387. A row constitutes a picking work history record representing a picking work history of one part. The date / time field 381 of each picking work history record stores the date and time when the picking work was performed, the section address field 382 stores the section address to be picked, and the actual product number field 383 stores the section address. The product name code of the part is displayed in the product name code field 384, the name of the manufacturer that manufactured the part is stored in the maker name field 385, and the part number is purchased in the lot number field 386. In the picking quantity column 387, the quantity of the picked part is stored.

  When parts are picked from a certain section, the number of the actual product slip IC tag 61 attached to the actual product slip 6 attached to the corresponding storage box 2 (FIG. 2) is read. It is transmitted to the database server 30 together with the picking quantity, and the database server 30 obtains the actual product slip number by referring to a correspondence table (not shown) from the transmitted actual product IC tag number and manages the actual product slip using the actual product slip number as a key. By retrieving the table 35, necessary information is obtained from the corresponding actual item record record, the picking work history record is generated, and added to the end of the picking work history table 38 and recorded.

The data example in FIG. 9 shows the recorded contents when the picking work is performed in the following order.
...
(1) Twenty parts with the product name code “P005” were picked from the section “A-2”.
(2) Three parts having the product name code “P001” are picked from the section “B-3”.
...

  Subsequently, referring to FIGS. 1, 3, and 4, according to the flowchart shown in FIGS. 10 and 11, a work procedure and a picking work procedure for storing the delivered supplemental parts in the parts shelf 1, The contents of the table update process executed at that time will be described in detail.

[Parts replenishment work procedure] (FIG. 10)
As described above, the parts to be replenished to the parts shelf 1 are delivered in a state of being stored in the replenishment storage box 2a by the amount of goods received (see FIG. 1).
When the delivered parts are replenished to the parts shelf 1, first, in step S11, the parts replenishment operator (or a picking operator) selects one delivered storage box 2a. In addition, when a plurality of replenishment storage boxes 2a have arrived, a part that is out of stock may be selected first.

  Next, in step S12, the parts replenishment operator determines the storage destination section of the part from the empty sections of the parts shelf 1, and stores the replenishment storage box 2a in the determined storage destination section. At this time, when there are a plurality of empty sections, it is preferable to select a section that seems to be most appropriate in consideration of the weight of parts, the expected picking frequency, and the like.

  Next, in step S13, the parts replenishment operator selects the actual product slip IC tag 61 attached to the actual product slip of the stored storage box 2a (storage box 2) and the compartment IC attached to the storage destination compartment. The tag 13 is read by the portable radio terminal 50, and a shelf allocation registration operation is executed by pressing a function key (see FIG. 4).

  As a result, a shelf allocation completion message including the actual product slip IC tag number and the section IC tag number is transmitted from the portable wireless terminal 50 to the database server 30 via the wireless base station 51 and the network 60, and the database server 30 obtains a corresponding product slip number and a partition address by referring to a correspondence table (not shown) from the actual product slip IC tag number and the partition IC tag number read from the message, and assigns parts to the partition Is stored in the partition management table 36, and a shelf allocation history record indicating that the allocation has been added is added to the head of the shelf allocation history table 37 and recorded. At this time, the value in the warehousing quantity column 356 of the actual product slip record stored in the actual product slip management table 35 is copied and written in the remaining quantity column 363 of the section management table 36.

  Although the parts replenishment work procedure has been described above, when the empty storage box 2b (FIG. 1) that has been emptied after all of the parts in the storage box 2 have been discharged, The release operation is executed, the part assignment of the corresponding section of the partition management table 36 is released, and a shelf allocation history record indicating that the allocation is released is additionally recorded in the shelf allocation history table 37.

[Picking procedure] (Fig. 11)
As described above, the picking operation is instructed by the picking list 7 attached to the empty container 3a for transporting the parts (see FIG. 1).
When performing the picking work, first, in step S21, the picking worker 4 selects one delivered empty container 3a and places it on the work table 5. When a plurality of empty containers 3a have arrived, a container destined for a specific delivery destination may be selected first.

Next, in step S22, the picking operator 4 takes out the picking list 7 attached to the selected empty container 3a, and for all parts described in the picking list 7 (see FIG. 3), the picking list 7 includes steps S23 to S26. Repeat the process.
In other words, the picking operator 4 searches the parts shelf 1 for the storage box 2 in which the parts that have not yet been picked are stored in step S23, and in step S24, affixes them to the actual product slip of the storage box 2. The in-stock item IC tag 61 is read by the portable wireless terminal 50, and the picking quantity is input by a ten key or the like. In step S25, the designated quantity of parts is taken out from the storage box 2 and placed on the work table 5. It moves to the empty container 3a placed, and finally, in step S26, a picking completion operation is executed by pressing a function key of the portable wireless terminal 50 (see FIG. 4).

  As a result, a picking completion message including the actual product slip IC tag number and the picking quantity is transmitted from the portable wireless terminal 50 to the database server 30 via the wireless base station 51 and the network 60. A corresponding section management record 36 is obtained by obtaining a corresponding section tag number by referring to a corresponding table (not shown) from the section tag IC tag number read from the message and searching the section management table 36 using the section tag number as a key. The picked partition address is obtained from, and a picking work history record is generated and added and recorded at the end of the picking work history table 38, and the picking is performed from the value of the remaining quantity column 363 of the partition management record. Subtract quantity.

In step S27, the picking operator 4 determines whether there is a next part that has not yet been picked, and if there is a next part (“Yes” in step S27), the process returns to step S23, and the next If there is no part (“No” in step S27), the process proceeds to step S28, where the worked container 3b placed on the workbench 5 is unloaded and the series of work ends (see FIG. 1).
In step S24, the actual product slip IC tag 61 is read. However, instead, the partition IC tag 13 is read, and the database server 30 searches the partition management table 36 using the partition address as a key. Also good.

  According to each work procedure described above, the section management table 36 provided in the database server 30 indicates the usage status of the parts shelf 1 and the shelf allocation history table 37 indicates each section performed on the parts shelf 1. In the picking work history table 38, the history of part picking work performed on the parts shelf 1 is recorded.

  Next, a method for providing the administrator with various information regarding the picking work recorded in the database server 30 will be described in detail.

  FIG. 12 shows the configuration and data example of the administrator startup screen 81 displayed on the display unit 45 of the administrator terminal 40 (FIG. 4).

  The manager activation screen 81 includes a parts shelf selection unit 811, a “shelf allocation status display” button 812, a “picking result display” button 813, and the like. The parts shelf selection unit 811 includes a selection result display unit 8111, a drop-down icon 8112, and a drop-down list 8113, and when the administrator selects the drop-down icon 8112 with the mouse or the like from the input unit 44 of the administrator terminal 40. The names of the parts shelves registered in advance in the system are displayed as a drop-down list 8113, and one of them can be selected. The data example of FIG. 12 shows a state where “component shelf c” is selected from the drop-down list 8113 and the name of the selected component shelf is displayed in the selection result display unit 8111.

  After the administrator selects a parts shelf for which information is to be obtained in this way, when either the “display shelf status display” button 812 or the “picking result display” button 813 is selected with a mouse or the like, the selected button is displayed. Accordingly, the display is switched to a shelf allocation status display screen 82 as shown in FIG. 13 or a picking frequency display screen 83 as shown in FIG. An “end” button 101 is a button for closing the manager start screen 81 and ending the process.

FIG. 13 shows a configuration and data example of the shelf allocation status display screen 82 displayed when the “shelf allocation status display” button 812 is selected on the manager activation screen 81.
In the following description, it is assumed that the selected parts shelf is composed of a total of 16 sections of 4 rows × 4 stages, but the number of rows and stages of the parts shelf is not limited to this.

  The shelf allocation status display screen 82 includes a shelf allocation status display section 821, an “additional allocation” button 822, an “allocation allocation” button 823, a “division change” button 824, a “division replacement” button 825, and the like. .

  The shelf allocation status display section 821 displays a 4 × 4 partition display section in a matrix state when the parts shelf is viewed from the front. The partition addresses are A column, B column, C column, D column in the order from the left, and the first, second, third, fourth in the order from the top. For example, in the second column from the left If it is the third section from the top, it is written as “B-3”.

  Each section display section constituting the matrix of the shelf allocation status display section 821 has information (for example, a product name code, a manufacturer name, and a lot number) for identifying the parts allocated to the section, and the remaining parts. The quantity is displayed. These pieces of information are read from the partition management table 36 in the database server 30 and transmitted to the manager terminal 40.

  The section display portion with hatching indicates that the corresponding section has no part currently allocated and the section is in an empty state.

• Are spare parts stored on the top or bottom of the shelf?
・ Is there too many or too few shelves?
・ Is the assignment of parts to the compartment fixed?
-Are there any parts that have not been used for a long time?
-Are there any parts that are about to expire?
-Are parts replenished properly?
・ Is the same part stored in several compartments?
・ Is the first-in first-out process for parts properly performed?
・ Is there any other problem with the current picking work?

  In the present embodiment, it has been described that only the number for identifying each IC tag is recorded in the IC tag. However, the actual product slip number corresponding to the actual product slip IC tag and various attribute information of the parts are described. May be recorded, or a section address corresponding to the section IC tag may be recorded. Further, the history of picking work may be recorded on the actual product slip IC tag, and the history data recorded when the actual product slip is collected may be transferred to the server.

Further, in this embodiment, the case where a so-called free address operation mode in which parts can be freely assigned to each section has been described, but the correspondence between each section and the parts is fixed. It can be easily applied to the fixed address system.
Furthermore, in the present embodiment, the case where the history of picking work is collected using the worker's mobile terminal has been described. However, the picking work instruction is displayed on the touch panel display attached to the work table, and the work is performed.
