DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading / unloading instruction device, and more particularly to a loading / unloading instruction device which can easily cope with a change of a storage section of an article shelf.

[0002]

2. Description of the Related Art When stocks of articles (products) are managed, even if the varieties of the products are the same, there are a plurality of colors, patterns, sizes (size, length, weight, etc.). Frequently increases and decreases. Conventionally, in shelf management, a system of one location (storage unit) and one item (commodity) (for example, see Japanese Patent Application Laid-Open No. 5-170312) is common. However, it is necessary to secure a shelf space in consideration of not only a shelf space corresponding to the stock amount but also a maximum stock amount to satisfy this method. In addition, such a system requires more shelf space than necessary, for example, due to seasonal fluctuations and new products.

[0003] Conventionally, as a storage and retrieval instruction apparatus which can easily cope with a change of a storage section, there is one as disclosed in Japanese Patent Publication No. 7-84245. This entry and exit instruction device,
A terminal device arranged on a cart for loading and unloading articles;
A transponder capable of reading and writing information related to an article from the terminal device of the cart in a non-contact manner, and a central device for communicating and processing information related to the entry / exit of the article with the terminal device of the cart. It is configured. The transponder is mounted on the shelf where the product is stored in a portable manner in units of appropriate blocks (storage units) in accordance with the form of the product. Item information such as "type (code) and number of items".

[0004] When articles are taken in and out, the terminal device receives and displays article information such as "shelves address, article code, and number" from the central apparatus. Then, based on the display, the worker moves the cart to the designated shelf, and takes out the transponder placed on the designated shelf. Then, the terminal device determines whether or not the item information of the terminal device and the item information of the transponder "match", and if they match, entry / exit of the item to / from the place where the storage device was placed. I do.

[0005]

However, in the above-mentioned entry / exit instruction device, the change of the arrangement of the storage section is dealt with by changing the position of the transponder which is mounted so as to be portable. Problem. That is, since the transponder is made portable, not only the transponder but also the central device cannot grasp in which position in the shelf the article to be taken out is stored. For this reason, even at the time of loading and unloading, the central device cannot instruct the terminal device on the position of the storage unit in the shelf. As a result, in order to confirm that the place where entry / exit is to be carried out is correct, it is necessary to perform a matching judgment operation between the article information of the terminal device and the article information of the transponder, resulting in a decrease in work efficiency.

The present invention has been made in view of the above-mentioned problems, and provides an entry / exit instruction device which can grasp the arrangement of a storage unit and instruct a worker to the location of the storage unit even if the arrangement of the storage unit is changed. The purpose is to provide.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an overall configuration of a storage and retrieval instruction apparatus 1 according to the present invention. This entry / exit instruction device 1
Instruction means 2 for instructing a worker on information on articles to be taken in and out, such as the location of a storage unit to be taken in and out and the number of articles.
And an information processing device 3 for performing processing relating to communication with the instruction means and entry / exit of articles. As shown in FIG. 2, the indicating means 2 includes article shelves 4a, 4b, 4c. . , And each of these article shelves 4 is provided with columns 5, 5,. . Between them, a horizontal rail 6 is erected to form a multi-stage shelf. The position of each horizontal rail 6 can be changed in the vertical direction, and the number of stages can be increased or decreased by changing the number of horizontal rails 6. Furthermore, the goods shelf 4
Are divided into one or two or more storage units 7, respectively.

Here, the storage unit 7 refers to a space in which a group of articles is to be stored, and the group of articles generally refers to a set of one type of articles. A collection of different types of articles may be used. In FIG. 2, no partition is provided between the adjacent storage units 7, but a partition or the like may be provided. In that case, the size of the storage unit 7
It is preferable to provide a partition so that the position can be changed so that the number can be changed. Also, as shown in FIG. 2, the article shelves 4 are arranged so that a plurality of them are arranged to form a row of article shelves. Although not shown, a plurality of rows of the article shelves are arranged in parallel so as to constitute an operator passage between the rows.

The information processing apparatus 3 sets a storage area 9 for representing each of the article shelves 4 and a section representing the arrangement of the storage unit 7 of the corresponding article shelves 4 in the storage area 9 in a resettable manner. And a communication unit 11 for transmitting and receiving data to and from the instruction unit 2. The storage area 9 is composed of a set of a plurality of basic areas 12 and is two-dimensional data obtained by dividing one article shelf 4 into a large number in the height direction and the horizontal direction. I have.

FIG. 3 shows the state of the storage area 9 corresponding to the article shelf 4a of FIG. 2 on the output means 14 such as a CRT, and the portion surrounded by a double line indicates the storage area 9. ing. As described above, the storage area 9 is divided into “9” in the direction corresponding to the lateral direction of the article shelf 4 and “9” in the direction corresponding to the height direction of the article shelf 4, for a total of 81 pieces. It is composed of a basic area (an area indicated by a dotted line in FIG. 3). Note that the number of the basic regions 12 may be other than the above number, but any number that can be displayed by one digit on the support means 2 is preferable because the structure of the support means 2 is simplified.
It is desirable that the number is such that the arrangement of the storage unit 7 can be changed. Therefore, "10" may be divided in the horizontal direction and "10" in the vertical direction, so that a total of 100 basic regions may be obtained. Further, the number of the basic regions 12 may be increased or decreased.

Each basic area 12 has a value in a direction corresponding to the horizontal direction of the article shelf 4a (a value of 1 to 9: hereinafter, referred to as a "number of cells") with respect to the lower left corner of the storage area 9 and an article shelf. 4
a in the direction corresponding to the height direction of a (values of 1 to 9:
"Referred to as" basic area step number "). For example,
If it is a basic area at the upper left corner of the storage area 9, the number of cells = 1,
The number of basic region steps = 9. The setting means 10 includes a keyboard
One or more basic areas 12 are combined based on input from input means 15 such as
The section corresponding to is set. As shown in FIG.
The partitioning of the storage area 9 is performed as follows (in FIG. 3, the partitions are indicated by solid lines).

As shown in the flowchart of FIG. 4, the section setting is performed after setting the steps (step S1) for setting the steps of the storage area 9 corresponding to the steps of the article shelf 4. Is set by setting the number of cells of the basic region 12 (step S2), and the settings are registered (step S3). Step setting (step S1)
As shown in the flowchart of FIG. 5, first, the number of the row of the article shelf to which the article shelf 4 to be set and the number of the article shelf 4 are input (step S4). Is specified. Then, in the case where the article shelf has a four-level configuration like the article shelf 4a in FIG. 2, the first and second levels of the storage area 9 are changed by the input means 15 while viewing the display as shown in FIG. Allocated to the first stage of the shelf 4a, and 3 to 5
It is input that the tier is assigned to the second tier of the shelf 4a, the sixth tier and the seventh tier are assigned to the third tier of the shelf 4a, and the eighth and ninth tiers are also assigned to the fourth tier of the shelf 4a. Step S
5).

Then, the setting means 10 divides the height direction of the storage area 9 into four steps as shown in FIG. 3 based on the input (hereinafter, each set step is referred to as a division step). If it is desired to continue setting the steps also for other article shelves 4, the process returns to step 4, and the article shelves 4 for which another step setting is desired are performed.
If not, the step setting (step S1) ends (step S6). In the mass setting (step S2), first, the number of partitions to be set is designated (step S2).
7). For example, if the user wants to set the cell of the section corresponding to the first row of the article shelf 4a in FIG. Then, as shown in the first row of the article shelf 4a in FIG.
When providing two storage units 7a, 7b, 7c, 7d,
The first cell and the second cell are placed one by one from the left end of the first row of the goods shelf 4a.
The third and fourth squares are assigned to the second storage unit 7b, the fifth and sixth squares are assigned to the third storage unit 7c, and the seventh to ninth squares are assigned to the third storage unit 7a. The user inputs that the information is to be allocated to the fourth storage unit 7d (step S8).

Then, based on the input, the setting means 10 sets the first partition of the storage area 9 to 4 as shown in FIG.
Divide into two. If the sizes of the storage units are the same, instead of inputting each allocation one by one, if the input unit 15 inputs 4 which is the number of storage units 7, the number of cells allocated to each storage unit is reduced. The automatic assignment may be performed so that the assignment is made as evenly as possible (for example, the above-described assignment). If it is desired to continue setting the mass for the other division stages (the second stage to the fourth stage), the process returns to step 7. If there is no other division stage for which the mass setting is desired, the mass setting ( Step S2) ends (step S9).

It should be noted that the input for the section setting may not be performed in accordance with the above-described procedure, and may be any input that specifies the number of basic areas and the number of squares of the basic area constituting the section for each section. Good. As described above, the storage area 9 is two-dimensional data obtained by dividing one article shelf 4 in the height direction and the horizontal direction, and the position of the basic area 12 in the storage area 9. Corresponds to the positional relationship in the article shelf 4, and therefore, when combining the basic areas 12 forming one section, it is only necessary to combine the basic areas 12 corresponding to the actual positions of the storage units 4. Therefore, input for section setting is easy.

When the arrangement of the storage unit 7 is changed, the partition setting may be performed again. Further, the setting means 10 sets the address 17 of each section after the section is set. The address 17 only needs to be able to uniquely specify each section in one storage area 9. Such an address 17 may be automatically set by the setting unit 10, or may be set by the input unit 15. May be set by the setting means 10 based on the input from the user. However, address 17
Is displayed as it is by the instructing means 2 and indicates the location of the storage unit 7 as described later, and may be set as shown in FIG.

That is, the address 17 in FIG. 3 indicates the number of steps in the storage unit 7 corresponding to the section and the number of cells in the lower left corner of the basic area 12 constituting the section (hereinafter referred to as the "number of frontage").
And a combination of For example, goods shelf 4
In the case of the section corresponding to the storage unit 7e on the right side of the fourth tier of “a”, the basic area at the lower left corner is the sixth square, so “4-6”
The address 17 is set as follows. As described above, if the address 17 is configured by the number of cells in any one of the basic areas constituting the section, the worker can be determined by the relevance between the position of the basic area and the position on the article shelf 4. Is
Just by looking at the address 17 displayed on the instruction means 2, the approximate location of the storage unit from which the article should be taken out can be determined.

Further, the number of frontage of the address 17 may be a number obtained by sequentially numbering the storage units 7 of each stage of the article shelf 4. That is, the address 1 of the section corresponding to the storage unit 7a
7 is “1-1”, the address 17 of the section corresponding to the storage unit 7b
May be "1-2", the address 17 of the section corresponding to the storage section 7c may be "1-3", and the address 17 of the section corresponding to the storage section 7d may be "1-4". In addition, the mass setting (step S2) does not need to set the entirety of a certain partition stage, and may be set while leaving an empty area as shown in FIG. In FIG. 7, a section marked with a cross (for example, “1-1”) is already set, and the other basic areas are empty areas. Then, when the number of articles stored in a certain storage unit 7 decreases, a part of the basic area constituting the section corresponding to the storage unit 7 is released (partition resetting) to make it an empty area. be able to.

When goods are stored, an empty shelf search process is performed to check a storage unit 7 (section) in which goods can be stored. This empty shelf search process is performed as shown in the flowchart of FIG. In the empty shelf search process, first, in order to specify the article shelf 7 to be searched, the number of the row of the article shelf and the number of the article shelf are instructed (step S10). Then, a search is performed for the article shelf 7 (step S1).
1). If there is no free space in the article shelf for storing the article, the process returns to step S10 and waits for the input of the number of another article shelf. If there is a free space, the storage area 9 corresponding to the article shelf is returned.
Is displayed (step S13).

Further, if it is necessary to change the section upon receipt of the article, the column setting (step S15) and the cell setting (step S16) are performed. If the section does not need to be changed, the article is stored. The address corresponding to the storage unit 7 to be executed is confirmed (step S17) (step S14). Then, the article number of the article is updated, and the quantity is input (step S18). Then, the setting and input contents are registered (step S19), and the article (product) is stored in the storage unit (step S20). Then, when there is another article being stored, the process returns to step S10, and otherwise, the process ends (step S21).

At the time of article retrieval, the address 17 and the number of articles to be taken out are indicated by the instruction means 2 via the communication section 11. The communication unit 11 transmits the address 17 and the number of articles to be taken out to the instructing means 2 and receives a signal by an operation performed in the instructing means 2 in response to an in / out request. The indicating means 2 displays the address 17 and the number of articles to be taken out, and is provided at a central position of each article shelf 4. The instruction means 2 includes a step number display section 19, a frontage display section 20, a quantity display section 21, a lighting section 22, a completion button 23, and a function button 24.

The step number display section 19 is for displaying the step number which is an element constituting the address 17, and is constituted by a green 7-segment single-digit LED. The frontage display unit 20 is for displaying the number of frontage which is an element constituting the address 17, and is a green 7-segment single-digit LED.
It is composed of The quantity display section 21 displays the quantity of articles to be taken out, and includes a red 7 segment 3
It is composed of a digit LED. The lighting section 22 is used for easily telling the worker that the storage section 7 from which the article is to be taken out is provided on the article shelf 4 provided with the indicating means 2 by lighting, and is constituted by a red LED. ing.

The completion button 23 is pressed when the loading and unloading is completed, thereby notifying the information processing apparatus 3 of the completion. When the function button 24 is pressed when the number of articles in the storage unit 7 is smaller than the required number of articles or the like, the function button 24 is used to perform out-of-stock communication that informs the information processing apparatus 3 that the retrieval cannot be performed. In addition, as shown in FIG. 2, a marker 26 representing each storage 7 is provided above the storage 7. This marking section 26 is shown in FIG.
As shown in FIG. 10A, a paper label 26a describing the number of frontage portions of the storage section ("3" in FIG. 10A) is held in a plastic case 26b. The plastic case upper part 26c is slidable in the horizontal direction with respect to the horizontal rail 6 of the article shelf 7, and is provided detachably.

As shown in FIG. 10B, the sign section 26 includes, in addition to the frontage number of the storage section 7, the number of stages of the storage section 7, the shelf number of the article shelf having the storage section, and the storage section. And a bar code 27 is provided.
This bar code 27 can be used when the goods are stored. The position of the marker 26 is changed or replaced when the arrangement of the storage 7 is changed. As described above, the change of the storage unit 7 can be dealt with only by the change of the sign unit 26 and the resetting of the partition of the storage area 9.
