Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product display management method and system suitable for obtaining product management information for managing product sales, inventory, etc. in a store.

[Conventional technology]

For the distribution industry, the information system is called a planogram or facing control system, and it supports product display planning and displays the product display status as an image on a display device. Discussed on page 72.

This conventional system generates an image that combines images of the front of the product, as if it were viewed from the front of a display shelf at a mass retailer. Furthermore, it is assumed that there will be no change in the predetermined display position of the product. Therefore, predetermined product position information is input into the computer system, and a product display image at that position is generated.

[Problem to be solved by the invention]

The above-mentioned conventional technology is for product display planning, and is based on the premise that product display in stores is carried out as planned. Therefore, it is sufficient to analyze product information such as sales results based on the product display position at the time of display planning. However, in cases such as clothing departments, where (1) new products are brought in daily and (2) product display positions change daily or moment by moment due to sales and sales activities, the products are not displayed in the same way as they are displayed. are rarely kept on display. Therefore, it is important to collect product display position information according to the actual display status and its changes in order to manage the product display status and its changes, as well as to manage product sales, inventory, etc. .

The above-mentioned conventional technology does not take into account the collection of product display position information, and has a problem in that it is not suitable for product display management on a sales floor where product display positions change frequently.

This kind of problem has never been recognized before, that is, the idea of managing the display position of products for products whose display positions change frequently has never existed.

An object of the present invention is to provide a product display management method and system suitable for easily obtaining product display position information and managing product display positions.

Another object of the invention is the sluice gate! ! JJ! It will become clear from the description in the drawings.

[Means to solve the problem]

The above purpose is to use a product display management method to read product codes of displayed products using a product code reading device in a predetermined order, input the read product code string into a computer system, and use the product display position information from the predetermined reading order information in the computer system. This is achieved by obtaining data and outputting product management information based on the obtained product display position data.

In addition, a product code reading device for reading displayed product codes is used, and product position information is obtained from the read product code I-column and a predetermined product code reading order, and product management information is obtained from the product position information. The above object is achieved by a product display management system comprising a computer device having a display device for outputting product management information.

Note that the product code reading device can read not only product codes but also codes having a code system similar to the product coat.

[Effect]

There are various types of product display fixtures, but for example, in the case of a row of hanger fixtures in a clothing store, the clothing items hung from the hangers are displayed in a straight line. In this case, if it is decided to read the product codes in order from the products at the end of the line, it is possible to identify the relative position of the product on the hanger fixture from the read product code string. Furthermore, on both ends of this bunker fixture, fixtures ■
By pasting two types of D codes and reading both fixture ID codes before and after reading the product code, it is possible to identify the product position on the hanger fixture even if the product code is read from any direction on the hanger fixture. . Furthermore, if the location of this hanger fixture in the store (position on the layout in the store), that is, the coordinates in the store of each fixture ID, is known, the location of the product in the store can be known.

The above is an explanation of the principle of determining product position data by reading the product code using hanger fixtures as an example. Even in the case of products placed in the front row, the order in which product codes are read can be determined in advance, such as reading from top to bottom or from left to right in the back row, and repeating this process until the front row is reached.
If you decide to read the fixture ID code affixed to a predetermined position inside the fixture, the principle of determining product position data will be the same. In the case of two-dimensionally arranged products, it is recommended to read the code at the end of the column and insert it between the product code columns.

A computer system that determines the product display position in the fixture from the read product code string determines the product display position on the premise that the products are arranged at uniform intervals in the fixture, so no particular problem occurs. This is because the number of products displayed on a certain fixture is limited by the thickness of the fixture, and in general, precise product positions on or within the fixture are not required in order to manage product display. If you are using fixtures that are extremely large in relation to the size of the product, attach the fixture ID code corresponding to the product arrangement (for each row if it is arranged in multiple rows, or at the break in the middle if it is a long row, etc.). Fixture ID
Each code affixed unit can be regarded as a temporary fixture (divided fixture).

〔Example〕

Before entering into detailed description of the embodiments, one of the features of the present invention will be explained.

Conventionally, various stores have read the product code of each product and processed the reading results by computer in order to remove the product from the shelves. Strictly speaking, a label indicating a product code such as a barcode (sometimes printed directly on the product or wrapping paper) was read by a reading device, and the product code (data) that was the reading result was processed by computer. .

However, in the past, the order in which the product coats were read for each product was not necessarily determined, and it was generally acceptable to read the product coats in any order. This is because, in the past, since the purpose was to grate products, it was sufficient to know the number of items for each product.

Given this conventional situation, there has been no idea up to now of trying to grasp the display status of products based on the read product code (column).

A feature of the present invention is that the product display status is obtained based on the read product code (column). For this purpose, we have to match the display position of the product.

The reading order of product codes is determined in advance, the corresponding product display position is recognized from the read product code (column), and the product display status (product management information) is obtained from the recognition result.

As a preferred embodiment of the present invention, in addition to the above-mentioned procedure, a fixture for displaying products is recognized.

By reading the product code in correspondence with the recognized fixture, the product display position can be more easily determined. The information for recognizing fixtures is the same as the product code.
The code assigned to each fixture (fixture code) is attached to the fixture as a label.

It can be obtained by reading the fixture code with the same device that reads the product code.

An embodiment of the present invention will be described below with reference to the drawings. Here, a description will be given of a clothing store as a typical example to which the present invention can be applied. The present invention is highly effective when applied to sales floors where the display positions of products can change.
For example, it can be applied to sales areas such as food and books.

FIG. 2(a) and FIG. 2(b) show an example of the configuration of a product display management system according to the present invention.

The system shown in FIG. 2(a) is comprised of a computer 100 and a barcode reader 101. The calculator 100 is
Output device 102. Input device 1o3゜File device 104
It has a memory 105 and a communication control device 108. The output device 102 outputs the product display status, and is a display or a printer. As will become clear from the description below, a terminal equipped with a color graphic display is desirable as the output device 102. Input double hit 1
03 may be any device that can input commands and data necessary for the execution of the computer 100, such as a keyboard or a pointing device (mouse, etc.).

The file device 104 is not necessarily a necessary component, but due to the capacity of the memory 105 and the amount of data to be processed,
Required when the amount of data is large.

This is a so-called external storage device, which includes magnetic disks,
Such as floppy disk 7. Depending on the case, it may be something like a memory card.

The barcode reader 101 communicates with the memory 106 at high
It has f107. The memory 1.06 is provided mainly to store data (product code and lifestyle code) read by the barcode reader. Here, the barcode reader 101 will be explained as a specific example of a device for reading product coats and fixture codes, but when using product codes and fixture codes based on code systems other than barcodes, the code system It goes without saying that a reader compatible with this should be used. In addition, if information corresponding to a product code or fixture code is displayed in uncoded form, that is, in symbols such as letters or numbers,
OCR (Optical Character Read
er) etc.

Communication between the communication control devices 107 and 108 is carried out by basic procedures via a modem, PAD device (
Packet Assembly Diaassemblyf
(Actility) Communication methods commonly used, such as packet communication via an audio coupler or communication via a telephone line.

The operation of the system shown in FIG. 2(a) will be explained.

A product coat label is attached to the product by the barcode reader 101 (the product code is shown on this label).
Read the product code from. The read product code is stored in memory 106.

The fixture code is also the same as the product code using the barcode reader 10.
1 and stored in memory 106. The order in which the product code and fixture code are read follows a predetermined order that will be described later. The product code and fixture code are stored in the memory 106 in the order in which they are read. The product codes and fixture codes stored in the memory 106 are read out by the communication control device 107 in the order in which they are stored in the memory 106, that is, in the order in which they are read by the barcode reader 101.
The data is transferred to the communication control device 108 of No. 0.

The communication control device 108 stores the transferred product codes and fixture codes in the memory 105 in the order in which they were transferred. The product code and fixture code stored in the memory 105 are
The code string file is transferred to the file device 104. What is the order in which product codes and fixture codes are stored in the code string file?

The order of reading by the barcode reader 101 is maintained. If the capacity of the memory 105 is sufficient to accommodate the aforementioned code string file, it is not necessarily necessary to use the file device 104. File '1110
Product management information is obtained by the computer 100 executing a predetermined process to be described later using the product code and fixture code stored as a code string file in 4.

This product management information is output to the output device 102.

Next, the system configuration shown in FIG. 2(b) will be explained. The system shown in FIG.
(a) The system is similar to the system shown in the figure. The difference lies in the method of transferring the product code and fixture code read by the barcode reader 101 to the memory 105 of the computer 100. 2(b) 1 barcode reader 10 as shown in Figure 2(b)
The product code and fixture code read in step 1 are stored in the memory card 108. Although not shown, the memory card 108 is attached to a memory card writer. The memory card storing the product code and fixture code is stored in the memory card reader 1 of Calculation (i) and OO.
02, and its contents, namely the product code and fixture code, are read.

The product code and fixture code read by the memory card reader 102 are stored in the memory 105.

The operations of the computer 100 after storing the product code and fixture code in the memory 105 are the same as in the case of FIG. 2(a) described above. In the case of the system configuration shown in FIG. 2(b), although the order in which the product codes and fixture codes are stored in the January memo card 108 and the like has not been mentioned, the order in which they are read by the barcode reader 101 is maintained. In both cases of FIG. 2(a) and FIG. 2(b), it is assumed that the storage order, transfer order, etc. of the product coat and fixture code are in the normal order with respect to the reading order by the barcode reader 101. Although it is desirable from the viewpoint of ease of processing, even if the order is reversed, it is possible to reverse the order by processing by the computer 100.

Although not shown, a modification of the system configuration shown in FIGS. 2(a) and 2(b) will be described.

The sales floor to which the present invention is applied is equipped with a POS (Poj, nt
ofSales) terminal is installed in the sales floor, and the PO8 terminal is often connected to the computer 100. In such a situation, considering the second (a) modification of the system configuration, the product code and fixture code from the barcode reader 101 may be transferred to the computer 100 via the PO8 terminal. There are barcode readers of this type that are already in practical use. Considering a modification of the system configuration shown in FIG. 2(b), a memory card reader is provided in the POS terminal, and the contents of the memory card 108 storing product codes and fixture codes are provided in the PO8 terminal using the barcode reader 101. Read with memory card reader, calculator 10
Just transfer it to 0. These modified sequences can be easily implemented by those skilled in the art given the above description.

A desirable system configuration from among the system configurations described above may be selected in consideration of the number of nine industry stores, the scale of each store, or the relationship with existing systems such as POS terminals.

FIG. 1 shows a functional flow diagram for explaining an embodiment of the present invention in an easy-to-understand manner.

First, a product code and a fixture code are read using the barcode reader 101 according to a predetermined reading order described later (step 2). The read product code and fixture code are stored in the memory 106. As already explained, the product code and fixture code stored in the memory 106 are input to the computer 100 and stored in the code string file 5 (step 4). Since the product codes and fixture codes stored in the code string file 5 are stored in the order in which they are read by the barcode reader 101, the display position of each product is determined using this order information, and the determination result is transferred to the product position data. Store in file 7 (step 6
). The display position information of each product stored in the product position data file 7 is output to the output device 102 as product management information 9 in a format that is easy for users of this system to use.

Hereinafter, each step will be described in detail according to the functional flow shown in FIG.

First, the reading of the product code and fixture coat in step 2 will be explained. The method of attaching the product code label representing the product code to the product is as described above. Fixture code label 11 i (i=a, b,
c, -) are attached to fixtures, for example, as shown in FIGS. 3(a) to 3(c). Fixture code labels 11a and llb are attached to both ends of the hanger fixture 110 as shown in FIG. 3(a). This fixture code label is sometimes called a fixture end barcode label. Third (
b) On the box shelf 111 as shown in the figure, each box has a fixture code label 11c.

11d and lie are attached. This fixture code label is sometimes called a shelf box barcode label. Third
(c) In the showcase 112 as shown in the figure, fixture code labels 1.1f and 11g are attached to each tier.

This fixture code label is sometimes called a showcase stage barcode label.

The pasting positions of the above-mentioned fixture coat labels are not limited to the locations shown in Figures 3(a) to 3(c).
As will be explained below, it is only necessary to be able to identify, for example, a shelf or the like according to the type of fixture.

Furthermore, for fixtures other than those shown in the figures, the position at which the fixture code label is attached may be determined depending on the characteristics of the fixture. This can be easily understood from the above examples and the following explanation.

The details of reading the product code and fixture code will be explained using FIG. 4. The procedure for reading the product coat and fixture code differs depending on the type of fixture (step 12).

If the fixture is the hanger fixture 110 shown in FIG. 3(a), the barcode label lla on one end of the fixture is read by the barcode reader 1.1 (step 13). continue,
The product barcode labels of each product are read by the barcode reader 101 in the order in which the products are displayed, from the one closest to the read fixture end barcode label lla toward the other fixture end barcode label llb (step 14). When the product barcode labels of all the products displayed on the hanger fixture 110 have been read, the barcode label 11b at the other end of the fixture is read by the barcode reader 101 (step 15).

If the fixture is box If 11 shown in FIG. 3(b), for example, the shelf box barcode 1 and label llc are read (step 16). Here, for example, a shelf box barcode label is affixed to each shelf of the box shelf, and the read fixture code is different for each shelf, so
This means that there is no need to consider the reading order relationship between columns. However, in preferred embodiments, a top-to-bottom or bottom-to-bottom order is appropriate. The barcode reader 101 reads the product barcode label in the box to which the next read shelf box barcode label LLC is affixed (step 17).The reading order of the product barcode labels in this case (if there are multiple products ) shall be in order from the top to the bottom of the stacked products or from the bottom to the top. When the product barcode labels of all the products in the shelf box have been read, an end code is input by pressing a predetermined button provided on the barcode reader 101 (step 18). Instead of inputting this end code, it is also possible to read the shelf box barcode label 11c again. Moreover, step 18 can also be omitted. This is because once the reading of the product barcode label of the displayed product on a certain box shelf is completed, the barcode of the next fixture will be read, so this fixture barcode can be used as a substitute for the end code. It is.

If the fixture is the showcase 112 shown in FIG. 3(c), the showcase stage barcode label 11f is read by the barcode reader 101 (step 19). In the case of the showcase 112, products are generally arranged two-dimensionally, as shown in FIG. 3(c). Therefore, when viewing the showcase 112 from the front, the barcode reader 101 reads the product barcode labels of the products in the innermost row from left to right or from right to left (
Step 20). Thereafter, an end code is input (step 21). The above process is repeated for each row toward the front of the showcase 112, and when the product barcode labels have been read for all products in the row (step 22), the end code is input (step 23). Regarding the end code input, the showcase bar code may be read again in the same way as in the case of the box shelf.

Note that there are many cases where the products are not arranged in rows within the showcase 112. In such a case, the product barcode labels may be read in an order close to the order in which the products are arranged in a row.

The above process is repeated for all fixtures such as the entire store, the entire sales floor, a specific sales floor, and a specific fixture (step 24).
).

During the above processing, each time a product (bar) coat label or fixture (bar) code label is read by the barcode reader 101, the read product code or fixture code is stored in the memory 1.
Stored in 0G. As mentioned above, the order in which product codes and fixture codes are stored in the memory 106 is determined by the barcode reader 1.
The reading order is based on 01.

After reading product codes and fixture codes in a predetermined order in the store, the code string (to product code and fixture code 1) stored in the memory 106 is transferred to the code string file 5 of the computer 100 in step 4. Transfer to.

As shown in FIG. 1, the computer 100 reads the product coat and fixture code strings from the code string file 5, calculates the fixture position coordinates of each product code (step 6), and writes the coordinates to the product position data file 7. The product position determination 6 is the reverse process of reading the product coat and fixture code shown in FIG. The process of reading barcode labels is
It is preferable to consider this process in place of the process of determining the product code writing position in the product position data file 7.

The structure of the product position data file 7 is shown in FIG. The product position data file 7 has data in the table structure shown in FIG. 5 for each store 115 or each sales floor, and includes the number of fixtures used in the store, that is, the fixture ID 116 and type for identifying n fixtures. 117, a fixture code 118 of a barcode label affixed to each fixture code 118, and its position coordinates 119. The product code column 120 consists of one column for hangers and one column for each row of showcases (however,
The code e represents a two-dimensional array), and in the case of a box shelf, each box is stored as one column of data. ai and bj in the figure represent product codes.

Once the product position data is stored in file 7,
The computer 100 processes the product position data in step 8 and outputs product management information 9.

A first example of outputting product management information based on product position data will be described. FIG. 6 shows a plan view of the store floor displayed on the output device 102. The floor plan shows hanger fixtures 1
10 and a showcase 112 are shown. Each fixture area is divided according to the number of products on display, and contains various product attribute information (color, pattern, etc.).

Size, design, etc.), hue, DH light, saturation, etc. color 1
Displayed according to gender. Display information other than product attribute information includes 1 price range and season code.

Examples include product age (number of days from purchase date). Regarding this display information, the status of the displayed products can be easily recognized on the layout as shown in FIG. 6.

The process of outputting product attribute information etc. as described above will be explained in detail. FIG. 7 shows a flowchart of the processing executed by the calculation Ia 100. First, the fixture position coordinates 119 of the product position data file 7 are input.

For example, the fixture I of the hanger fixture 110a shown in FIG.
Assuming that D is 1, from Fig. 5, the coordinates (X□, y,
) and (Xzr yj. Similarly, enter the position coordinates of all fixtures on the displayed floor (step 29). Next, count the number of products on each fixture (
Step 30). The number of products is counted by counting the number of product codes in the product code column 120 of the product position data file 7. For example, for a hanger with fixture ID 1, a work, b2. Since a is a product code, its number Q is counted. Next, the position coordinates of each product are calculated for each fixture (step 31). A method of calculating the position coordinates of each product will be explained using FIG. FIG. 8 shows the hanger fixture 110 of FIG.
A is shown enlarged. The origin in FIG. 8 is a predetermined arbitrary point on the entire floor shown in FIG. 6. This is because the number of products displayed on the hanger fixture 110a is zero.

The coordinates (xI, yl) of the display position of product i (i=1.2...,Q) are determined as follows.

When looking at the product on the floor layout, it is desirable that the product has a certain size, so it is sufficient to display a shape of a predetermined size centered on the seat MA (Xt+yl).

In the case of products that can be packed and displayed, such as clothing, if the specified size cannot be secured, the distance between adjacent items on the same fixture may be divided into equal parts to reduce the specified shape, or the size may be reduced in one direction. It can be compressed and displayed. FIG. 8 shows a case where there is sufficient space between adjacent products. The process of step 31 is repeated for all products displayed on the same fixture (step 32), and steps 30 and 31 are repeated for all target fixtures (step 33). As a result, the contents of the product coordinate file 70 shown in FIG. 9 are obtained.

In FIG. 1, the product position data file 7 and the product coordinate file 7o are representatively shown as the product position data file 7.

Next, product information is output to the display device 102 on the floor layout (step 33).

In step 33, the attributes of each displayed product are read from the product master 71 (product masks will be described later),
As shown in FIG. 6, display information is output in a predetermined shape, such as a rectangle, corresponding to the displayed product, and filled with color or hatched in accordance with the attribute value of the displayed product.

A second example of outputting product management information based on product display performance data is shown in FIG. In this example, while a worker collecting display information at five stores scans the barcodes of displayed products using a handy barcode scanner,
Problems with product display are displayed on a handy barcode scanner. Therefore, in the process flow shown in FIG. 10, first step 36) reads the product code string on the fixture from the product position data file 7, and then stores the product attributes, such as color and size, for each product code in the product master. 7
1 (step 37). Generally, when displaying products, attributes such as color, shade, size, etc. are arranged in a predetermined order (for example, the same color or pattern is ordered by size, 9 hues, etc.) because it looks bad and discourages purchasers if they are displayed randomly. This is desirable. In step 40, the attribute values are sorted and the sorted product order is compared with the actual display order.

It is detected whether or not there is a problematic displayed product that causes a difference by referring to the attribute information read from the product mask. If there is a problem product, in an abnormality warning display step 41, the product name, product attributes, display location, etc. of the problem display product are displayed on the display section 42 of the handy barcode scanner.

A third embodiment of product management information output is shown in FIGS. 11 to 13. Here, from product display position data and product image information prepared in advance, a product display image that is similar to what you would see if you were standing in the store is obtained. Figure 11 (1
) schematically shows images of all products that may be displayed. The image of each product is separated into a mold image (centered on the outline) and a pattern image (9-color coat) through image processing in advance.
The product image mask table 71 shown in FIG. 11 (2), which corresponds to the # of the former two and the color code, is l(i). FIG. 11 (3) shows an example of a mold image and a pattern image. 12 (a)
and (b) shows the process of creating a product display image hung on a hanger fixture from the product coat row in the product position data file 7. Embed the innermost composite product image in the hanger fixture image. Next, the previous composite product image is superimposed. At this time, if you leave the image outside the product outline as it is and fill only the inside with the data of the image you want to overlap,
It looks like the products are stacked on a hanger, and by repeating this process, a hanger image with all the products hung can be obtained as shown in FIG. 12(b). FIG. 13 shows a processing flow diagram for executing the above on a computer. The fixture TD specified by the terminal is accepted (step 44). In step 45, the image of the designated fixture is written from the fixture image master 46 into the image memory 47. In step 48, the product position data file 7 is searched for the product code string of the designated fixture, and for each product code, the product master 71 (9th
With reference to Figure (2)), obtain the corresponding type image # and pattern image #9 color code. In step 51, the product image master 52 (FIG. 9(3)) is referred to, the mold image and pattern image are read, and both lines are combined.Furthermore, in step 53, color combination is performed based on the color coat. In step 54, the image memo 47
The fixture image is read out from the image and the composite product image is superimposed on it.

By repeating the above composite image overlapping process for all product codes, hanger display image data is obtained on the image memory 47, and the image output process 55 transfers this to the output device 1.
Display on 02.

14 and 15 explain the fourth embodiment, and the floor level 4 of FIG. 6 is explained based on the product display position information.
711 to display the sales position and loss position on the diagram. In step 57, sales data within the period (t□ to ci2) is cut out from the sales data file 58. Step 5
At step 9, the display product code string at the time point 2 is read out from the product display position data file 7, a search is made for the sales product, and if a corresponding product is found, that is set as the sales product position. On the other hand, in FIG.
The product display position at the time is read from the file 7, and a search for the product on display at the time is performed using sales data for the product on display at the second time, and the position of the product for which the search was unsuccessful is found. In steps 6o and 63, the sold item positions and loss positions found by one or more are outputted to the output device 102.

(Effects of the Invention) According to the present invention, product codes are read in a predetermined order, and product display position data can be obtained using a computer system based on the predetermined order information. Display location information can be obtained and an appropriate product display management method can be provided.
