Description

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 compartment in the shelf to grasp the storage state of the article on the shelf and managing the storage of the article. It is a thing.

[0002]

2. Description of the Related Art A shelf for storing articles is usually used for organizing and storing the articles. Particularly when the article is, for example, a certain type of product group, and out of stock of any of the product group must be avoided as much as possible, considerable attention is paid to inventory management of the shelf.

Further, when the 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 sold to each sales base. The delivery center for delivery must properly formulate a daily delivery plan and put the plan into practice in an optimal state, and the formulation of a delivery plan for that purpose is also an important task.

Conventionally, the management of the storage state of the storage items on the shelves as described above has been handled by the end sales bases, and the situation is sent to the central command center by telephone or facsimile or by inputting input by a computer terminal. Based on the contacted inventory information, the central command center creates a delivery plan that concretely shows the loading amount and delivery route of each item, and the delivery center is based on this delivery plan. The system of executing delivery is adopted.

However, in the above-mentioned inventory management system, regarding the management of the inventory at the end sales base, the person in charge checks the forms of inventory management one by one, or the items actually stored in the shelves are checked. Although it is necessary to recognize the stored state, these are extremely time-consuming and cumbersome operations, and errors are highly likely to occur. Further, the checked stock status is transmitted to the central command center by telephone, facsimile, or by computer terminal of each sales office, so that a considerable loss of time occurs.

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

[0007]

By the way, in order to complete the above-mentioned online system, it is indispensable to configure the article storage shelves themselves to detect the stock status of the articles. It is expected that the structure will be quite complicated. And even if the structure is complicated, it is possible to manufacture one that can detect whether or not a predetermined article is present in a predetermined section of the shelf. There are major obstacles to manufacturing in mass production.

This is because the state of the articles stored on the shelves is not always the same at many end sales bases. For example, at one sales base, the main product is A, but at other sales bases, the product B is the main product, and the quantity is different, so the situation at all sales bases is different. .

Then, the article storage shelves must be matched to the characteristics of each sales base.
Specifically, the arrangement status of the sensors that detect the presence or absence of the article, and the wiring that transmits the signals detected by the sensors, etc., must be different for all sales bases.

If all of these demands are to be dealt with in the shelf manufacturing process, the manufacture of the shelf will be extremely complicated, and it will be very inefficient.

The present invention has been made to solve the above problems, and at the end sales base,
It is an object of the present invention to provide an article storage shelf that can easily mount a sensor and also assemble a shelf including wiring of signal lines.

[0012]

According to a first aspect of the present invention, there is provided an article storage shelf which is formed between a pair of left and right side walls and has a compartment for storing articles separately. In the article storage shelf provided with a sensor means for detecting the presence or absence of article storage for each section and transmitting a signal,
The shelf plate is composed of a side wall bridge shelf bridged to a pair of left and right side walls, and a sensor support plate that suspends sensor means attached to the lower portion of the side wall bridge shelf. The locking screw is screwed with the head down, and the sensor support plate has a hole through which the locking screw head can pass and the locking screw head connected to this hole cannot pass through. And a perforation consisting of various holes is formed.

[0013]

According to the above-mentioned article storage shelf, the shelf board is formed with compartments for storing the articles separately, and the articles are stored in the compartments in a state of being separated from other articles. Therefore, by limiting the storage of articles in this compartment to only one article of a predetermined item, it is possible to avoid confusion with other articles, and it is possible to reliably detect the presence or absence of storage in that compartment on the shelf. Suitable to do.

Further, since at least one sensor means is provided for each compartment in the compartment, when an article is stored in the compartment, the sensor means detects it. Conversely, if you pull out the item from the shelf compartment,
The sensor means detects that no articles are stored in the compartment.

Since a locking screw is screwed on the bridge between the side walls with the head thereof facing downward, the locking screw is formed through the hole through which the locking screw can pass. Body of the locking screw by horizontally moving the sensor support plate in the direction in which the locking screw head communicated with the hole cannot pass through, as it fits into the head of the locking screw. Is locked. If the locking screw is fastened in this state, the sensor support plate is mounted on the side wall bridge shelf.

When the sensor means is mounted or replaced, the locking screw is loosened to loosen it.
Since the strong fastening state of the sensor support plate to the side wall bridge shelf is released, the above-mentioned mounting operation and replacement operation are facilitated.

Further, a passage hole is formed in the sensor support plate for passing a signal line derived from the sensor means, and a signal line for bundling the signal lines passing through the passage hole is provided in an upper rear part of the sensor support plate. Since the collecting groove is provided, many signal lines derived from each 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 assembling of a complicatedly configured shelf is facilitated. It is not necessary to complete it in a state that meets the user specifications, and it becomes possible to leave the assembly operation to the end user. As a result, the manufacturing process of the goods storage shelves can be simplified, and the end user can assemble and wire under the necessary and sufficient conditions according to his or her situation, and prevent wasteful excess equipment. It will be convenient for both producers and consumers.

A column-shaped hook 32 is provided on the rack so as to project toward the opening of the shelf body 1a. At the tip of the hook 32, a nail-shaped head portion is provided as a retainer. The front end portion 21b of the inter-sidewall bridge shelf 21 has a tip portion of the hook 32.
It is located at the bottom of.

The sensor means 4 is suspended from the pair of hooks 32. FIG. 5 is a perspective view showing an example of the sensor means, and FIG. 6 is a sectional view taken along the line AA. First, as shown in FIG. 5, the sensor means 4 includes a plate-shaped sensor 41 for detecting a change in its own posture and the plate-shaped sensor 41.
And a protective film 42 laminated on the surface of the. The vertical dimension of the protective film 42 is made longer than that of the plate-shaped sensor 41. As shown in FIG. 1, the lower end portion of the protective film 42 is substantially on the upper surface of the shelf plate 2 when the sensor means 4 is suspended from the hook 32. The length is set so that they touch each other.

The plate-shaped sensor 41 and the protective film 42 are sandwiched at their upper ends by a U-shaped sandwiching member 43 and fixed by rivets. Further, a pair of left and right locking holes 44 are bored on both sides of the holding member 43, and these locking holes 44 are fitted into the hooks 32 provided on the first vertical wall 3 a of the sensor support plate 3. As a result, the sensor means 4 becomes the shelf board 2.
It will be suspended from the ceiling of the.

As shown in FIG. 6, for example, the plate-like sensor 41 is constructed by enclosing a piezoelectric element 41b in two covers 41a. This piezoelectric element 41b generates an electromotive force when pressure is applied from the outside. Therefore, the piezoelectric element 41 is bent by bending the plate sensor 41.
When b is pressed, a signal indicating it is sent to the piezoelectric element 41.
It is possible to detect that the plate-shaped sensor 41 has been bent by the signal transmitted from b. The connecting means 4 is connected to the sensor means 4 via a signal line 46 for transmitting the above-mentioned signal.
5 are provided. Connection terminal 45 of each sensor means 4
Is connected to an outlet (not shown) provided in the shelf body 1a, collected in the repeater 5 arranged at the upper part of the shelf body 1a, and transmitted by electric power via a telephone line.

The sensor means 4 is used in this embodiment.
The piezoelectric element 41b is used in the above.
The mechanism is not limited to b, and any mechanism may be adopted as long as the mechanism is such that a switch is turned on and current is supplied when the posture of the sensor means 4 changes.

One of the sensor means 4 is provided in one section R of the minimum unit partitioned by the partition member 24 on the surface of the shelf board 2. Therefore, one of the partition members 24
If the front part of the section R of the part becomes large after being removed, it means that two sensor means 4 are provided in the one section R.

7 and 8 are sectional views showing a state in which the sensor means is attached and detached. 7 shows a state in which the sensor means 4 is attached, and FIG. 8 shows a state in which the sensor means 4 is attached and detached. As shown in these drawings, in order to suspend the sensor means 4 on the hook 32 of the sensor support plate 3, the locking screw 21g connecting the inter-sidewall bridge shelf 21 and the sensor support plate 3 to each other is used. 21f is loosened by turning the sensor support plate 3 shown in FIG. 8 from the state shown in FIG.
Is in a state of falling forward. Then, the bridge between the side walls 2
Since a considerable gap is formed between 1 and the hook 32,
The sensor means 4 can be attached to and detached from the hook 32 as shown by the arrow. When the screw hole 21e is tightened, the state shown in FIG. 7 is restored.

Since the article storage shelf 1 of the present invention is constructed as described above, first, the number of the compartments 24 formed on the upper surface of the shelf board 2 is set appropriately on the cover plate 23 of the partition member 24. By setting it, it can be set arbitrarily as an integral multiple of the minimum span.

The side wall bridge shelf 2 of the sensor support plate 3
1 is mounted on the sensor support plate 3 by inserting the hole 3f of the keyhole-shaped perforation 30 formed on the first horizontal surface 3b of the sensor support plate 3 into the inter-sidewall bridge shelf 2
1 is fitted into the head portion 21f of the locking screw 21g screwed to 1, and in that state the sensor support plate 3 is translated in the direction of the cutout groove 3g, and the head portion 21f is rotated to fasten the locking screw 21g. The sensor support plate 3 can be easily removed from the side wall bridge shelf 21 by performing the reverse operation to the above.

As described above, the fact that the sensor support plate 3 can be easily attached to and detached from the side wall bridge shelf 21 is that the sensor means 4 is attached to the sensor support plate 3 and the signal line 46.
It is shown that the wiring operation is easy.

As described above, the article storage shelf 1 of the present invention is
Since the setting of the R width of one section, the mounting 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 end sales base. It is possible to assemble the article storage rack 1 that matches the situation of the sales base.

A system to which the article storage shelf of the present invention is applied will be described below. In a state where articles are not stored in a predetermined section of the shelf board 2, as shown in FIGS. 1, 2, 5, and 7, the sensor means 4 suspended on the ceiling portion of the shelf board 2 is Since it is in a state of being hung straight from the hook 32 of the sensor support plate 3 and no external force is particularly applied to the piezoelectric element 41b provided in the plate-shaped sensor 41, no signal is transmitted from it and the shelf The section R of the plate 2 indicates that no articles are stored.

FIG. 9 exemplifies a state in which articles B are stored in a predetermined section R of the shelf board 2. As shown in this figure, when the article B is stored in a predetermined section R of the shelf 2, one upper end of the article B abuts on the protective film 42 of the sensor means 4 and splashes it upward. In order to raise it, the plate-shaped sensor 41 laminated on the back surface of this protective film 42
Can be flipped up as well.

Then, the plate-like sensor 41 shown in FIG.
The piezoelectric element 41b held between the pair of covers 41a is bent, and as a result, a weak current indicating that the article B is stored in the predetermined one section R is generated. This current is used as an article storage signal and is shown in FIG.
5 and a repeater 5 shown in FIG. 1 to lead to a predetermined telephone line.

When the stored article B is taken out from a predetermined section R of the shelf board 2, the sensor means 4 returns to the original state of hanging from the hook 32. A weak current stops flowing through the element 41b. This is led out from the connection terminal 45 to the telephone line as a signal indicating that the article B is taken out.

Since the above-mentioned telephone line is connected to a computer as a central control unit provided in a central command center, the storage status of the articles in the shelf board 2 of the article storage shelf 1 can always be grasped at the same time. It is in the state, and it becomes possible to take actions such as inventory replenishment quickly and appropriately.

FIG. 10 is an explanatory view showing an example of a simultaneous centralized inventory management system using the article storage rack of the present invention. As shown in this figure, article storage shelves 101, 102, ..., 10N are arranged at the end sales bases, respectively. These article storage shelves 1 include repeaters 51, 52, ...
.., 6N, and a repeater C1 are connected to a computer provided in a central command center.

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

For example, in the case of the article storage shelf 101 shown in the figure, since the article B is not stored in the compartment R1 and the sensor means 401 is in a hanging state, the article B is present in this compartment R1. It is determined not to do so, and the signal indicating that there is a stored item is not transmitted from the sensor unit 401. On the other hand, articles B are stored in the compartments R2 and R3, and the lower ends of the sensor means 402 and 403 are flipped upward. Therefore, these sensor means 4 detect that there is a stored item in the compartment R, and the signal is transmitted to the computer C.

The following article storage shelves 102, ..., 10N
Also has the same structure as the above-mentioned article storage shelf 101. Therefore, the computer C provided in the central command center always has the article storage shelves 101, 102, ...
The storage information of the article B for each section R is input from 10N. Then, in the computer C, each of the article storage shelves 101, 102, ...
A program for calculating the item, quantity, delivery order, etc. of the item B to be replenished to 10N is input.

Therefore, referring to the output of the calculation result by the computer C, the predetermined goods B are systematically delivered from the distribution center to the goods storage shelves 1 of the respective sales bases.
The period of stock-out can be suppressed to a minimum, and the complicated manual storage of the article storage shelves 1 and the erroneous delivery due to a contact error as in the past can be eliminated.
