Retrieval takes time, and the advantages of automated warehouses are halved.

Furthermore, the quantity to be taken out will also be inaccurate.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an apparatus for checking the quantity of articles to be taken out and taken out, which can quickly and reliably take out a desired quantity when taking out a large number of articles of the same type.

A special purpose of the present invention is to quickly and quickly confirm the quantity of goods when taking them out and carrying them in, so that the advantages of automated warehouses can be maximized.
The objective is to provide a device that can perform this accurately.

This is a device for confirming the quantity of goods to be taken in and taken out, which is equipped with a display that indicates whether the quantity is less than or equal to the quantity.

The following is a block diagram showing an embodiment in which the present invention is used with an automated warehouse.

Referring to FIG. 1, reference numeral 1 denotes a conventionally known automated warehouse, which uses container codes or position codes (hereinafter abbreviated as container codes) for taking out and storing article storage containers.

A keyboard 2 is provided for inputting information and for specifying whether to take out or store the container.

Various types of such automatic warehouses are known (for example, see US Pat. No. 3,526,326 and Japanese Patent Application Laid-open No. 49-33366), and therefore a description of their structure and operation will be omitted here.

In this embodiment, the keyboard 2 is provided with keys for entering the quantity of articles according to the invention.

The storage device 3, which receives the container code signal from the keyboard 2, stores the weight of each article stored in each container, and stores the weight of each article contained in each container according to the input container code signal. Outputs a weight information signal per piece.

The scale 4 is an electric or electronic scale that measures the weight of a suitable number of articles and outputs the weight as an electrical signal.

The arithmetic circuit 5 is equipped with multiplication, division, and subtraction functions, and receives the quantity information signal input from the keyboard 2 and the storage device 3.
A total weight information signal is output by multiplying (unit weight) x (quantity) by (total weight) with the unit weight information signal from .

The arithmetic circuit 5 also divides the weighing signal from the scale 4 and the unit weight information signal from the storage device 3 by dividing (weighing value) ÷ (unit weight) 1 (number of weighed pieces), and divides the result and the above-mentioned From the quantity signal from the keyboard, (quantity to be measured) - (quantity) 1 - 1 difference number 1 is subtracted, and a difference number information signal is output.

The comparison circuit 6 compares the total weight information signal of the arithmetic circuit 5 with the measuring device 4.
The circuit receives the weighing signal from the weighing signal and compares the total weight with the weighed value, and outputs three types of signals depending on whether the weighed value is greater than, less than, or equal to the total weight.

The display circuit 7 inputs the difference number information signal of the arithmetic circuit 5 and displays the number, and also inputs the output of the comparison circuit 6 and displays whether it is larger, smaller, or the same depending on the comparison result. .

When a user wants to take out a certain quantity of a certain item, for example, 100 screws of a particular size, he inputs the container code of the container containing the screws and the quantity 100 on the keyboard 2.

The automated warehouse 1 carries out the container to the warehouse take-out port using a known operation.

Here, when the user takes out an appropriate number of screws (generally considered to be close to 100) from the container and places them on the weighing device 4, the weight is measured and the measured value is converted into an electrical signal. It is applied to the arithmetic circuit 6.

At this time, the arithmetic circuit 5 has already received the weight signal of the single screw from the storage device 3 and the desired quantity 100 from the key chain 2, and the total weight has been calculated. has been entered.

When the weighing signal is input, the arithmetic circuit 5 calculates the above-mentioned difference number, and supplies the difference number information signal to the display 7 to display the difference number.

As a result, the user can know how many screws placed on the measuring instrument 4 are in error from the desired number of 100 screws.

On the other hand, a comparison circuit 6 compares the measured value with the desired total weight based on the total weight information signal from the calculator 5 and the weighing signal from the measuring device 4, outputs whether it is greater, less than, or the same, and displays the result. The results are displayed on instrument 7.

Therefore, the user can know whether the above-mentioned error is more or less than 100, and according to this display and the above-mentioned number display, the user continues to press the scale 4 until the display shows that they are equal. By adding or removing these items, the desired number of 100 screws will be taken out on the scale 4.

As a result, the user does not have to count the screws one by one, and even if a large number of screws are to be taken out, the desired number of screws can be taken out in a short time.

Further, when it is desired to store a desired number of screws, for example 100 screws, in a desired container, the same procedure as described above can be performed.

However, in this case, the screws to be placed on the measuring instrument 4 are not taken out from the containers that have been taken out to the takeout port of the automated warehouse, but are screws prepared for addition, and if the display circuit 7 above shows the same value, What is necessary is to insert the screw on the measuring instrument 4 into the container and operate the keyboard 2 to store the container in a predetermined position.

FIG. 2 is a block diagram of a modification of FIG. 1, in which the same parts as in FIG. 1 are designated by the same reference numerals.

In this modification, in the embodiment shown in FIG. 1, containers are taken out manually using the container position code from the keyboard 2, and the unit weight of the articles in each container is read out from the storage device 3 by inputting the same container position code. However, instead of the container location code, the key fob 2' now allows you to enter the article code, and the storage device 3'
, the unit weight of each article and the code of the container in which each article is stored are stored, and the article-specific code inputted using the key fob 2 is given as an input to the storage device 3', whereby data from the storage device 3' is stored. The container code and unit weight information signal of the article are sent to an automatic warehouse control circuit 8 (not shown in FIG. 1, but the same control circuit receives the container code from the keyboard 2 and performs container takeout/storage operations). It is something.

) and the arithmetic circuit 5, respectively.

The remaining circuits and operations are the same as in the case of FIG.

According to this modification, the user does not need to know the container code of the desired article, but simply inputs only the code of the desired article and its quantity on the keyboard 2', and the counting and confirmation of the quantity is carried out by the method shown in FIG. As explained in the example, it is possible to place the articles on the scale 4 and increase or decrease the number of articles while looking at the display 7.

2. As shown in FIG. 2, if the container return command signal from the keyboard 2' is sent to the control circuit 8 via the signal representing "equal" from the comparator circuit 6 and the AND circuit 9, the predetermined Even if a container return command is input from the key fob 2' before taking out the waste, there is no risk that the container will be returned and stored.

It is clear that the same sickle arrangement is also provided in the case of FIG.

As is clear from the above explanation, according to the present invention, it is possible to automatically, accurately and quickly know whether the number of articles is insufficient or exceeds the desired quantity, and therefore the desired quantity of articles can be taken out extremely quickly and accurately. It will be held on.

Moreover, it is therefore possible to particularly take advantage of the advantages of automated warehouses, and at the same time, increase utilization efficiency.
