〔Example〕

Hereinafter, a logistics management system according to an embodiment of the present invention will be described with reference to the drawings.

In the figure, the storage container (1) is the roller conveyor (2)
The robot is transported in the direction of arrow a and stopped in front of the worker, even though it is not shown. At this location, a weight detection mechanism (3) is provided below the roller conveyor (2), and this consists of a weight transmission plate (4) and a pair of load cells (5).
The weight detection signal from 5) is supplied to a weight calculator (6), and the calculation result from this is supplied to a storage number command device (7).

On one side of the storage container (1), an identification device (8) (hereinafter referred to as
(simply referred to as a tag) is attached, the details of which are shown in Figure 3, and a storage number command device (7).
Various types of data are transmitted and received between the antenna (9) and the antenna (9). This device (7) further has a display section αQ, on which the number of predetermined articles to be put into the storage container (1) at this time is displayed. According to the second aspect of the present invention, this device (7)
A buzzer CI sword is also attached to it.

The details of the tag (8) are shown in FIG.
, a control section (c), a memory circuit (b), a transmitting section (b), and an antenna (4). 1
) The number of predetermined articles to be stored at this position is stored. The antenna (g) receives a trigger signal from the antenna (9) of the storage number command device (7), and this signal is supplied to the memory α4 via the receiving section (2) and the control section (2), and the through the transmitter (to),
The above-mentioned identification data, required number of articles, etc. are transmitted from the antenna (4) to the storage number command device (7).

Like the tag (8), the storage number command device (7) also includes a receiving section, a transmitting section, a control section, a memo IJZ, etc.
Further, according to the present invention, the memory of each tag is provided with a function of rewriting or writing to the memory, and the memory circuit is provided with the function of rewriting the memory of each tag, and the memory circuit is provided with the function of rewriting the memory of each tag, and storing the single weight of a predetermined article at this location,
Contains various arithmetic circuits.

Although the embodiment of the present invention is configured as described above,
Next, this effect will be explained.

Suppose now that the storage container (1) comes to a stop in front of the worker. Since a weight detection mechanism (3) is provided at this location, the weight of the storage container (1) at this time is detected, calculated by the weight calculator (6), and calculated by the storage number command device (
7). On the other hand, this device (7) and tag (8)
Tag (8) is sent and received as described above.
The required number of items stored in the memory α is sent as data, and this number, for example 10 items, is displayed on the display section. The operator looks at the display section αq and knows that 10 items are required, takes out 10 items from the items piled up nearby, and puts them into the storage container (1). In this case, it is only necessary to put 10 items at a time, but depending on the size of the items, they may be placed one at a time into the storage container (1). In any case, store 10 pieces in a container (1)
Since it is a fixed article when it enters, it has a predetermined weight,
By multiplying this single weight by 10, the total weight of the items when the required number of items are included is determined by the storage quantity command device (
Since the calculation has already been performed in step 7), this is compared with the output from the weight calculation unit (6), and if they are equal, a warning is issued from the buzzer circuit. From this, the operator knows that he has indeed put in the required number of predetermined items. In addition, in the display part 4, if you put in one piece at a time, this will be subtracted, and when you put in the required number, it will be "0".
It may be displayed as As described above, in this embodiment, the total weight corresponding to the required number of predetermined articles is calculated in the article storage number command device, and the total weight of the articles actually put into the storage container (1) is calculated. The increased weight of the entire storage container is compared, and when they match, a buzzer is pressed so that it sounds, so if it does not sound, it means that the number of items is less or more than the predetermined number, so the operator can be sure. You can insert the required number of items written on the tag (8) and move forward.

The above explanation describes a case where 10 items can be stored in the storage container (1), but in reality, this storage container (1) stores a predetermined number of each type of item at each predetermined position on the upstream side. Therefore, in the predetermined position shown in the figure, these items occupy a considerable capacity, and in some cases, as shown in Figure 2, if this article m is not stored any more, Although it does not fall outward when it is overflowing and stopped, there is a risk that it may fall outward due to vibration or shock when being conveyed on the roller conveyor (2). The case where it is determined that n exists will be explained with reference to FIG.

Near this predetermined position, storage containers of the same shape and size as the empty storage container (1) are piled up, and the worker pushes the storage container (1) downstream or The container is advanced downstream by operating a nearby switch, and the new empty storage container (a) is placed on a predetermined position, that is, on top of the weight detection mechanism (3).

In addition, when moving the previous storage container (1) downstream, if there are 7 people and 3 items are still missing, the storage container number command device (7) will send the signal from the weight calculator (6). Then, it is determined that three pieces are still missing, and the number data signal indicating the remaining number is sent to a new storage container (A).
When it is transmitted as a write signal to the storage unit of the tag (21j) attached to the tag (21j), the number of articles actually inhaled into the tag (8) of the previous storage container (1), 7, is sent as a rewrite signal. Therefore, the signal that was previously written as 10 pieces will be changed to 7 pieces.By putting the remaining 3 pieces into this second storage container, if the number matches the number written on this tag Qυ, the goods will be stored. The comparator indicates a match at the number command wave R(n), and the buzzer sounds. Therefore, the operator should check the tag (
Confirm that the required number of predetermined items to be stored at this predetermined location written in step 8) has been stored in the storage container (1). Therefore, this second storage container (4) is also pushed away or guided to the downstream side by operating a switch.

Note that at the storage container take-out position on the downstream side, it is necessary to detect whether or not various required items are stored in one storage container.In this case, as shown in FIG. When using the storage container (1), data indicating that the items are stored separately in the container (1) is transmitted from the storage number command device (7) to the tag (8) or the tag (8) of either storage container (1) or (4). All you have to do is have Qυ record it in its memory.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto and can be modified in various ways.

For example, in the above embodiment, a load cell (5) is used as the weight detection mechanism, but instead of this, a strain gauge may be attached to a part of the roller conveyor.

Further, in the above embodiments, it is assumed that other articles are already contained in the storage container (1) on the upstream side, but the storage container (1) may be empty and reach a predetermined position. In this case, the first
If we consider the storage container (1) as the above-mentioned second storage container, even if the third, fourth, etc. empty storage containers are used, the claims of the present specification will not be satisfied. It is within the scope.

Further, in the above embodiment, a buzzer sounds when the required number of items are put into the storage container, but a lamp may be lit instead of the buzzer. In addition, on the display section, the required number is displayed first, but when the required number is put in, it is displayed as ``0 copy'', and when more pieces are added, +1 and +2 may be displayed.

〔Effect of the invention〕

As described above, according to the physical distribution management system of the present invention, an operator can always safely and reliably store the required number of items in a predetermined location in a storage container. Therefore, logistics can be managed reliably.
