Abstract

PROBLEM TO BE SOLVED: To always seize the total stock by incorporating gravimeters using a pressure sensor such as a strain gauge into shelf boards of a warehouse shelf or the like, and detecting and displaying a quantity of a commodity, a product, a part or the like loaded on the shelf in real time. SOLUTION: Articles are placed on shelf boards 1, and gravimeters are respectively incorporated into lower parts of the shelf boards 1 with respective shelf boards 1. Since the gravimeters are built in the shelf boards 1, there is the necessity of thinning a thickness of a gravimeter main body to the the possible minimum level by considering a space of a showcase, a warehouse shelf or the like. Therefor, for example, a pressure sensor such as a metallic plate and a strain gauge is used as the gravimeters, and a load on the shelf boards 1 is received by the metallic plate, and strain of the metallic plate generated at this time is detected by the strain gauge. After its detecting signal is amplified by an amplifying circuit, an operation is performed by an operation circuit, and it is displayed on a display panel 2 as the number. A correcting circuit is incorporated into the display panel 2, and when objects placed on the shelf boards 1 change, an object is preplaced by one piece, and display is corrected to 1, and the setting is changed, and the number is always displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic inventory device for calculating the number of articles such as display shelves.

[0002]

2. Description of the Related Art Conventionally, stocktaking operations are performed by manually checking the quantity of each product, product, part, etc., and calculating inventory. There has been no automatic inventory device that can be implemented whenever it is desired to carry out this inventory in a labor-saving or labor-saving manner.

[0003]

In recent years, with the diversification of consumer needs and the rapid pace of new product development by manufacturers, merchants have been forced to have more types of stocks than ever before. However, having large stocks of various varieties for merchants is a major hindrance to improving management efficiency.
For this reason, it is a big issue to always keep proper inventory by grasping top selling products and finely managing inventory. For that purpose, quick and accurate inventory is indispensable. However, there has not been a device for managing the quantity on a warehouse shelf or a display shelf, so that the operator has to rely on humans to check the stock amount. This has been a major obstacle to the automation of inventory.

An object of the present invention is to automate this inventory work,
Labor saving. The aim is to make inventory management more appropriate by routinely performing inventory, which is usually performed every fiscal year, and to achieve more efficient management.

[0005]

SUMMARY OF THE INVENTION The purpose of stocktaking is to accurately ascertain the stock quantity of commodities, products, parts and the like. However, the only way to check the quantity of goods, products, parts, and the like stacked on display shelves, warehouse shelves, and the like was to count people.
The present invention incorporates a weighing scale using a pressure sensor such as a strain gauge on a shelf plate such as a display shelf or a warehouse shelf to detect and display the quantity of goods, products, parts, etc. stacked on the shelf in real time. , It was always possible to grasp the amount of stock.

[0006]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an external view showing an embodiment of an automatic inventory system according to the present invention, FIG. 2 is a sectional view of a weighing scale incorporated in a display shelf, and FIG. It is a block diagram showing a part. In FIG. 1, an article is placed on a shelf 1 and a weighing scale shown in FIG. 2 is incorporated in each of the shelves below the shelf.

The weighing scale is built in the shelf. Therefore, it is necessary to reduce the thickness of the weighing scale body as much as possible in consideration of spaces such as display shelves and warehouse shelves. The weighing scale uses a metal plate and a pressure sensor such as a strain gauge, receives the load on the shelf plate with the metal plate, and detects the strain of the metal plate generated at this time by the strain gauge. The electric resistance of the strain gauge changes when a strain occurs due to its characteristics. Utilizing this characteristic, the load detected as strain of the metal plate is converted into an electric signal by a strain gauge and output. Since the strain gauge has a thickness of about several millimeters and a metal plate of about one or two millimeters, it has become possible to incorporate a weighing scale in the shelf.

However, when the metal plate itself is used as a shelf, there is a possibility that a measurement error may occur depending on the position where the load is applied. For this reason, as a double structure consisting of a shelf plate on which products, products, parts, etc. are placed and a metal plate for measurement, the load on the shelf is applied to a fixed point on the metal plate for measurement, and errors due to differences in the positions where objects are placed Eliminated outbreak.

In a weighing scale, a strain gauge is brought into close contact with one end of a metal plate or a metal rod adapted to the weight of an article or the like placed on a shelf, and the strain gauge detects a metal strain caused by applying a weight to the other end. Thus, a signal proportional to the weight applied to the shelf is output. After the output signal is amplified by the amplifier circuit, it is calculated by the arithmetic circuit and displayed on the two display panels as the number. A correction circuit is incorporated in the display panel, and when an object to be placed on the shelf changes, the setting can be easily changed by placing one object in advance and correcting the display to 1, and the number is always displayed. be able to.

FIG. 4 is an external view showing an example in which a strain gauge is used for a hanger type display shelf, and FIG. 5 is an external view showing an example in which a strain gauge is used for a hanging display shelf.

The output signal is input to the computer 4 on-line, and advanced inventory management software such as daily inventory calculation and order processing at the time of dividing the appropriate inventory using software for inventory management. Can build a management system.

In this embodiment, a pressure sensor is used as a weighing scale, but a spring-type weighing scale can be used. Although the display shelf is taken as an example here, the display shelf can also be used as a warehouse shelf.

[0014]

As described above, according to the present invention, the quantity of goods, products, parts and the like placed on display shelves and warehouse shelves can be constantly monitored and grasped, so that the stocktaking work can be largely saved. Rather, it enables fine-grained management of inventory, greatly contributing to management efficiency such as reducing inventory investment.
