DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article storage shelf used for detecting the presence or absence of an article in each storage section in a shelf, grasping the storage state of the article on the shelf, and managing the storage of the article. Things.

[0002]

2. Description of the Related Art A shelf for storing articles is usually used for organizing and storing the articles. In particular, when the article is, for example, a certain product group, and it is necessary to avoid running out of stock as much as possible in any of the product groups, considerable attention is paid to shelf inventory management.

In addition, when shelves for storing and managing the products are arranged at geographically dispersed sales bases such as branch offices and sales agents, in addition to the above-mentioned focus at each sales base, goods are stored at each sales base. The delivery center to deliver must properly formulate a daily delivery plan and execute the plan in an optimal state. Planning a delivery plan for that is also an important task.

Conventionally, the management of the storage state of the stored articles on the shelf as described above has been handled by a terminal sales base, and the situation is controlled by a telephone, facsimile, or a computer input terminal by inputting to a central command center. Based on the notified inventory information, a delivery plan is prepared at the central command center, in which the loading amount of each article and the delivery route are specifically shown, and based on this delivery plan, the delivery center A system that executes delivery is adopted.

However, in the above-described inventory management system, regarding the inventory management at the terminal sales base, a person in charge checks the inventory management forms one by one or checks the items actually stored on the shelves. It is necessary to confirm the storage state, but this is an extremely time-consuming and complicated operation, and there is a high possibility that an error will occur. Further, since the checked stock status is transmitted to the central command center by telephone, facsimile, or input by a computer terminal of each business office, a considerable time loss occurs in this exchange.

Therefore, the article storage shelf itself is provided with a function of detecting the stock status of the stored articles, and the result of this detection is transmitted online to a central distribution center using a telephone line or the like, and the result of the detection is received. At the central distribution center, it is conceivable to construct an online system that creates a daily distribution plan using a large computer.

[0007]

By the way, in order to complete the above-mentioned online system, it is essential to configure the article storage shelf itself to detect the stock status of the article. It is expected that the structure will be considerably complicated. And even if the structure is complicated, it is possible to manufacture a product that can detect whether or not a predetermined article is present in a predetermined section of the shelf, but such a shelf can be uniformly manufactured. There are significant obstacles to mass production.

This is because the state of the articles stored on the shelves is not always the same at many terminal sales bases. For example, at one sales base, the main product is A, but at another sales base, the product B is the main product, and the quantity is also different. .

Then, the article storage shelves must be matched to the characteristics of each sales base.
Specifically, the arrangement of sensors for detecting the presence / absence of articles, and the wiring for transmitting signals detected by the sensors, and the like, must be different for every sales base.

[0010] If all of these demands are to be addressed in the shelf manufacturing process, the manufacture of the shelf becomes extremely complicated and extremely inefficient.

[0011] The present invention has been made to solve the above problems, and at a sales base at the terminal,
It is an object of the present invention to provide an article storage shelf capable of easily mounting a sensor and assembling a shelf including signal line wiring.

[0012]

According to a first aspect of the present invention, there is provided an article storage shelf formed between a pair of left and right side walls and having a partition for storing articles separately for each article. And, in an article storage shelf provided with sensor means for detecting the presence or absence of article storage for each section and transmitting a signal,
The shelf board is constituted by a bridge between side walls bridged by a pair of left and right side walls, and a sensor support plate on which sensor means attached to a lower portion of the bridge between side walls are suspended. Is screwed with the head screw down, the sensor support plate has a hole through which the head of the locking screw can pass, and the head of the locking screw connected to this hole cannot pass through And a perforation formed of a large hole.

[0013]

According to the above-mentioned article storage shelf, a section is formed on the shelf plate for storing each article separately, and the article is stored in the above-mentioned section in a state of being separated from other articles. Therefore, by limiting the storage of articles in this section to only one article of a predetermined item, confusion with other articles can be avoided, and the presence or absence of storage in that section on the shelf can be reliably detected. Suitable to do.

Further, since at least one sensor means is provided for each section in the section, if an article is stored in the section, this is detected by the sensor means. Conversely, when you pull out items from the shelf section,
The sensor means detects that no article is stored in the compartment.

Since the locking screw is screwed on the bridge between the side walls with its head downward, the hole through which the locking screw formed in the sensor support plate can pass is inserted into the locking screw. The sensor support plate is horizontally moved in the direction of the hole through which the head of the locking screw connected to the hole cannot pass, so that the main body of the locking screw is moved. Is locked. If the locking screw is tightened in this state, the sensor support plate will be mounted on the bridge between the side walls.

When mounting or replacing the sensor means, the locking screw is loosened,
Since the strong fastening state of the sensor supporting plate to the bridge between the side walls is released, the mounting operation and the replacing operation are facilitated.

Further, the sensor support plate is provided with a through hole for passing a signal line derived from the sensor means, and a signal line for bundling the signal line passing through the through hole at an upper rear portion of the sensor support plate. Since the collecting groove is provided, many signal lines derived from the respective sensor means can be led out of the system in an orderly manner.

As described above, according to the article storage shelf of the present invention, many sensor means are provided, and the assembling of a complicatedly constructed shelf is facilitated. There is no need to complete the work in conformity with the user specifications, and the assembly operation can be left to the end user. As a result, the manufacturing process of the article storage shelf can be simplified, and the end user can perform assembling and wiring work under necessary and sufficient conditions according to his / her own situation, thus preventing unnecessary excess equipment beforehand. It will be convenient for both producers and consumers.

As described above, the article storage shelf 1 of the present invention
Since the setting of one section R width, the attachment of the sensor means 4, and the wiring operation of the signal line 46 can be easily performed, the final assembling operation of the article storage shelf 1 can be sufficiently performed even at the terminal sales base. The article storage shelves 1 that match the situation of the sales base can be assembled.

Hereinafter, a system to which the article storage shelf of the present invention is applied will be described. In a state where no articles are stored in a predetermined section of the shelf 2, as shown in FIGS. 1, 2, 5 and 7, the sensor means 4 suspended from the ceiling of the shelf 2 Since it is in a state of hanging straight down from the hook 32 of the sensor support plate 3 and no external force is applied to the piezoelectric element 41b provided in the plate-shaped sensor 41, no signal is transmitted from the piezoelectric element 41b. That section R of the plate 2 indicates that no articles are stored.

FIG. 9 illustrates a state in which an article B is stored in a predetermined section R of the shelf 2. As shown in this figure, when an article B is stored in a predetermined section R of the shelf 2, one upper end of the article B comes into contact with the protective film 42 of the sensor means 4 and bounces it upward. The plate-shaped sensor 41 laminated on the back surface of the protective film 42
Can be jumped up as well.

Then, the plate sensor 41 shown in FIG.
The piezoelectric element 41b sandwiched between the pair of covers 41a is bent, and as a result, a weak current is generated indicating that the article B is stored in the predetermined section R. This current is used as an article storage signal by the signal line 46 and the connection terminal 4 shown in FIG.
5 and a predetermined telephone line via the repeater 5 shown in FIG.

When the stored article B is taken out from a predetermined section R of the shelf 2, the sensor means 4 is suspended from the hook 32 as before. No weak current flows through the element 41b. This is output from the connection terminal 45 to the telephone line as a signal indicating that the article B has been taken out.

Since the telephone line is connected to a computer serving as a central control unit provided at a central command center, the state of storage of articles in the shelf 2 of the article storage shelf 1 is always simultaneously grasped. In this state, actions such as stock replenishment can be performed quickly and appropriately.

FIG. 10 is an explanatory diagram showing an example of a simultaneous centralized inventory management system using the article storage shelf of the present invention. As shown in this figure, article storage shelves 101, 102,... These article storage shelves 1 are provided with repeaters 51, 52,.
.. 5N, telephone lines 61, 62,..., 6N, and a computer provided at a central command center via a repeater C1.

For example, the article storage shelf 101 is provided with sections R1, R2, R3 for storing the article B,
In these sections R, sensor means 401, 402, 40
3 are provided. As described above, when the article B is stored in the section R, the sensor means 4 is pushed and tilted to detect that the article B is stored. The detection result in each section R is input to the computer C as a central control unit via the repeater 51, the telephone line 61, and the repeater C1.

For example, in the case of the illustrated article storage shelf 101, the article R is not stored in the section R1 and the sensor means 401 is in a hanging state, so that the article B exists in the section R1. It is determined not to do so, and a signal indicating that there is a stored item is not transmitted from the sensor unit 401. On the other hand, the articles B are stored in the sections R2 and R3, and the lower ends of the sensor means 402 and 403 are jumped upward. Accordingly, these sensor means 4 detect that there is a stored item in the section R and transmit a signal to the computer C.

The following article storage shelves 102,..., 10N
Is configured similarly to the article storage shelf 101 described above. Accordingly, the computer C provided in the central command center always has the article storage shelves 101, 102,.
.., 10N, storage information of the article B for each section R is input. Then, the computer C preliminarily stores the article storage shelves 101, 102,.
A program for calculating the item, quantity, delivery order and the like of the article B to be refilled in 10N is input.

Therefore, with reference to the output of the calculation result by the computer C, the predetermined article B is systematically delivered from the distribution center to the article storage shelves 1 of each sales base.
The period of stock-out can be minimized, and the troublesome management of the article storage shelves 1 and erroneous delivery due to a contact error as in the related art can be eliminated.
