Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic weighing apparatus such as an electronic counting scale which measures the total weight of articles and calculates and displays the number of articles from the total weight and unit weight.

[0002]

2. Description of the Related Art Electronic balance devices such as conventional electronic counting scales are
In order to improve the workability when counting the number of items, a certain value (this is called a set point) near the target number to be counted is set in advance before counting the number of items. There is a so-called set point function that informs the fact that the count value of the electronic balance device exceeds the set point by a buzzer or the like.

According to this set point function, an operator can place an article on a weighing pan of an electronic weighing device without being conscious of the target number until a notification is given by a buzzer or the like. When there is a notification such as the above, it is sufficient to adjust the number of articles to be placed on the weighing pan so that the target number is reached, so that the efficiency of the counting operation for counting the target number is improved.

The electronic balance device having the set point function described above is disclosed, for example, in the following publications. First, in Japanese Unexamined Patent Publication No. 61-237020, an operator enters numerical values of a reference weight (reference number), an upper limit and a lower limit of a permissible range (hereinafter referred to as set point percentage) with a numeric keypad, and the upper limit and the lower limit are set. Disclosed is an electronic weighing device which calculates a lower limit set point, displays the calculation result, and blinks the display when the measured value (count value) exceeds the upper limit or when the measured value does not reach the lower limit to notify the operator. ing. Further, in this publication, the upper and lower limit values are calculated and registered in advance by setting the allowable range by the set point percentage for each article number of the article before weighing (counting) the article. It is also disclosed that, when weighing (counting), an operator inputs the article number with a ten-key pad and calls up the upper and lower limit values corresponding to the article to configure the electronic weighing apparatus.

Further, in Japanese Unexamined Patent Publication No. 64-66522, the upper limit value and the lower limit value of the permissible range are set by inputting numerical values by numeric keys and function keys, inputting by weighing, or set point percentage by numeric keys and function keys. If the measured value is within the allowable range by entering any of the
Alternatively, there is disclosed an electronic weighing device that sounds a buzzer or blinks a display when the device is not inserted.

By the way, the present applicant integrated the above-mentioned electronic weighing device with a carousel in which articles are stored, and controls the carousel by the electronic weighing device, and at the same time, allows the electronic weighing device to store various kinds of articles and the like. An inventory management device for carrying out goods, managing inventory, etc. was first proposed (for example, Japanese Patent Application No. 1-22).
5548 and Japanese Patent Application No. 1-284629, the specification and drawings attached to each application).

In addition to the carousel and the electronic weighing device, the inventory management device further includes a first storage means for storing reservation data including an item number, which is identification data of the item, and the number of articles shipped or received. There is provided second storage means for storing the storage position data (shelf number) indicating the storage position of the article in the carousel corresponding to the article number and the current inventory quantity. Then, when the worker inputs the reservation data in advance and makes a reservation for entry / exit, and then instructs the start of entry / exit work, the reserved and sorted article numbers are sorted in the order of the shelf numbers and the delivery numbers corresponding to these article numbers. The number or the number of warehousing is read out and displayed on a display, and the carousel is driven based on the shelf number so that warehousing / unloading work can be performed.

[0008]

By the way, in the above-mentioned conventional electronic weighing apparatus such as the electronic counting scale, the value of the set point needs to be changed according to the kind of the article and the target number of articles. This is because, in general, when counting items with a large unit weight or large shapes, the number of items that can be held by the operator is limited, and the items are placed little by little on the weighing pan. It is better to set the points closer to the target number, and conversely, when counting items with a small unit weight or small shape, the number of items the operator can hold at one time is large, and Since a large number of articles are placed at one time, it is better to set the set point smaller than the target number as compared with the case of counting articles having a large unit weight or articles having a large shape.

However, in the above-mentioned conventional electronic weighing devices, the reference weight (reference number), set point (or set point percentage), or article number is changed every time the type of the item to be counted or the target number is changed. There is a drawback that it is very troublesome because it requires key input. However, when counting items using only the electronic weighing device, it is necessary to key in the target number of items to be counted and the item number. At this time, also enter the set point or set point percentage. Even so, the total working time does not become so long.

However, in the case of the warehousing / leaving work based on the warehousing / leaving reservation in the above-described conventional inventory management apparatus, it is not possible to key in the set point or the set point percentage every time the reservation data is read and displayed. This is a very troublesome work, and the efficiency of the loading and unloading work is greatly reduced, and further, there is a problem that an incorrect set point or a set point percentage is keyed. The present invention has been made under such a background, and an object thereof is to provide an electronic weighing apparatus in which an accurate set point is automatically set according to an article to be counted and a target number.

[0011]

SUMMARY OF THE INVENTION According to the present invention, there is provided determination means for determining set point percentage, which is a percentage of the vicinity of the target number to be counted, corresponding to the unit weight of the article, the target number, and First calculating means for calculating a set point, which is a value near the target number, based on the set point percentage determined by the determining means; weighing means for weighing the total weight of the article; A second calculating means for calculating the number of the articles based on the weight and the unit weight; and an informing means for informing that when the number reaches the set point. There is.

[0012]

According to the present invention, when the determining means determines the set point percentage corresponding to the unit weight of the article, the first point
The calculation means calculates the set point based on the target number and the set point percentage. The weighing means weighs the total weight of the article. As a result, the second calculating unit calculates the number of articles based on the total weight and the unit weight, so that when the number reaches the set point, the notifying unit notifies that fact.

On the label or receipt. Further, reference numeral 10 is a carousel control unit for controlling a carousel (not shown) composed of a plurality of shelves on which trays for accommodating a plurality of articles are placed, and an operator gives an instruction to start loading and unloading. Thus, the shelf number data is transmitted, the shelf on which the tray storing the corresponding article is placed is rotated to a position where it can be easily taken out based on the shelf number data, and the position where the article is taken out is notified by the indicator light. For details of the configuration of the inventory management device including an electronic weighing device and a rotating rack (not shown), refer to the specification and drawings attached to the above-mentioned Japanese Patent Application No. 1-225548. In addition, 11
Is a buzzer, lamp, etc. that informs in different ways that the count value is equal to the target number or exceeds the set point when the count value becomes equal to the target number or exceeds the set point due to counting work. It is a notification unit.

In such a structure, first, the operator operates the touch panel 6a of the operation unit 6, the ten-key and function keys 6b, and the alphabet keys 6c, and uses the scale 2 to perform the preset shown in FIG. Preset data and reservation data are stored in advance in the data file 8a and the reservation data file 8b shown in FIG.

First, of the preset data, the unit weight is stored in the preset data file 8a shown in FIG. 3 by the following procedure. First, the operator uses the ten-key pad and the function key 6b of the operation unit 6 to key in the article number of the article whose unit weight is to be calculated, and then places ten such articles on the scale 2 shown in FIG. Then, the numeric keypad and the function key 6 of the operation unit 6
Key in "10 pieces have been placed" with b or the like.
As a result, the CPU 1 inputs the weighing signal corresponding to the weighing result transferred from the scale 2, divides the total weight of the article by the number 10, and sets the division result as the unit weight of the article, as shown in FIG. It is stored in the area of the corresponding article number of the data file 8a. The operation described above is repeated for all articles handled by this electronic weighing device.

Further, the reservation data is stored in the reservation data file 8b shown in FIG. 4 by the following procedure. That is, the operator uses the ten-key pad of the operation unit 6 and the function keys 6b to key in the article number and the target number of articles. As a result, the CPU 1 stores the keyed-in article number and the target quantity in the reservation data file 8b shown in FIG. The operation described above is repeated for all articles handled by this electronic weighing device.

Further, the operator previously investigates the relationship between the unit weight and the set point percentage for all the articles handled by the electronic weighing apparatus, and then the touch panel 6a of the operation unit 6, the ten-key pad and the function keys 6b.
And the alphabet keys 6c are operated to store them in the set point data file 8c shown in FIG.
In addition, as described above, generally, an article having a large unit weight tends to have a high set point percentage, and an article having a small unit weight tends to have a low set point percentage.

Next, the operation of the CPU 1 when carrying out the shipping operation will be described with reference to the flowchart of FIG.
When the operator operates the touch panel 6a of the operation unit 6 or the function key 6b to set the electronic weighing apparatus to the shipping operation mode, the CPU 1 proceeds to step SP1 shown in FIG. 6 and reserves the data file 8b shown in FIG. After reading the reservation data (article number and target quantity) stored in the top row of, the process proceeds to step SP2.

In step SP2, preset data (product name and unit weight) corresponding to the product number of the reservation data read in the process of step SP1 is read from the preset data file 8a shown in FIG. 3, and the product name, unit weight and After displaying the article number and the target number read in the process of step SP1 on the display unit 5, the process proceeds to step SP3.

At step SP3, the unit weight read out by the processing at step SP2 is sequentially compared to find out which unit weight range of the set point data file 8c shown in FIG. 5, and the set point percentage corresponding thereto is found. Is read from the set point data file 8c and stored in the set point percentage register of the RAM 8, and then the process proceeds to step SP4.

At step SP4, the target number of reserved data read at the processing at step SP1 and the set point percentage read at the processing at step SP3 and stored in the set point percentage register are substituted into the formula shown below. Then, the set point is calculated, and the rounded result is stored in the set point register of the RAM 8 as a set point, and then the process proceeds to step SP5. Set point = target number x set point percentage ÷ 1
00

At step SP5, the operator displays the display 5
When the article having the product name displayed on is taken out from the tray notified by the indicator light of the carousel (not shown) and placed on the scale 3 of the weighing unit 4, the CPU 1 causes the total weight of the articles measured by the weighing unit 4 to be measured. Is divided by the unit weight read out in the processing of step SP2, and the result of the division is rounded to the nearest decimal point and stored in the count value register as a count value. Go to.

In step SP6, it is determined whether or not the count value stored in the count value register is equal to or greater than the set point stored in the set point register. If the result of this determination is "YES", the flow proceeds to step SP7.
In step SP7, the count value stored in the count value register is compared with the target number read in the process of step SP1 to determine whether the count value is equal to the target number. If the result of this determination is "YES", then step S
Go to P8. In step SP8, the buzzer having a predetermined tone color of the notification unit 11 is sounded, and then the process proceeds to step SP10.

On the other hand, if the determination result in step SP7 is "NO", that is, if the count value is not equal to the target number, the process proceeds to step SP9. Step SP9
Then, after sounding a buzzer having a tone color different from that of step SP8 of the notification unit 11, step SP10
Go to. Also, when the result of the determination in step SP6 is "NO", that is, when the count value stored in the count value register is smaller than the set point stored in the set point register, the process proceeds to step SP10.

At step SP10, it is determined whether or not there is a key input for advancing to the next reservation data of the reservation data file 8b shown in FIG. This determination is made, for example, by whether or not the operator has pressed the [NEXT] key on the touch panel 6a of the operation unit 6, which is a key for instructing the reading of the next reservation data. This judgment result is "NO"
In the case of, it returns to step SP5 and repeats the processing of steps SP5 to SP9 described above. Then, the worker can use the scale 3 of the weighing section 4 for the article having the product name displayed on the display section 5.
By repeating the placement on the touch panel, it is determined that the count value and the target number have become equal in the processing of step SP7, and the fact is notified in the processing of step SP8. 6
When the [NEXT] key of a is pressed, the determination result of step SP10 becomes "YES", and the CPU 1 determines
Proceed to 11.

In step SP11, it is determined whether or not the article counted in the processing of steps SP5 to SP9 described above relates to the last reservation data. This judgment is made, for example, by preliminarily storing data indicating that all the reservation data have ended in the next stage of the last reservation data of the reservation data and detecting the data. Alternatively, a counter relating to the processing of the reservation data is provided, the counter is cleared before the processing of step SP1, and the value of the counter is incremented by 1 every time the processing of one article is completed, and all the reservation data are processed. It is determined whether or not the value of the counter at the end of is equal to the preset maximum value. Then, when the result of the determination in step SP11 is "NO", the process returns to step SP1 and the above-described processing of SP1 to SP10 is repeated. On the other hand, when the determination result of step SP11 is "YES", that is, the above-mentioned step SP5.
If the item counted in the processing of SP9 is related to the last reservation data, the series of operations is ended.

In the above-described embodiment, an example in which the count value is notified only when it is smaller than the target number is shown, but the present invention is not limited to this. For example, first, the value obtained by subtracting the set point percentage from 100 is added to 100 to calculate the upper limit value of the set point percentage. Then, the upper limit value of the set point is calculated based on the upper limit value of the set point percentage, and the above step SP is performed.
The set point range centered on the target number may be set together with the set point obtained in the process of 4, and the notification unit 11 may notify that the count value is within the set point range.

Further, in the above-mentioned embodiment, an example in which the set point percentage corresponding to the unit weight is determined by using the set point data file 8c which stores the relationship between the unit weight and the set point percentage is shown. It is not limited to this. For example, it is possible to perform a predetermined calculation on the unit weight and determine the set point percentage by calculation. Also, set point data file 8
c is not limited to one type, and a plurality of types are provided for each type of article (eg, classified by the specific gravity of the article), and one of these can be appropriately selected and used by designating the type of the article. Can also be considered.

Further, in the above-described embodiment, the reservation data is stored in advance in the reservation data file 8b before the delivery operation is performed, and the CP is stored at the time of the delivery operation.
The example in which U1 sequentially reads the reservation data from the reservation data file 8b has been shown, but the present invention is not limited to this. For example,
The worker may key in the article number and the target number with the operation unit 6 during the delivery operation.

[0033]

As described above, according to the present invention, since an accurate set point is automatically set according to the articles to be counted and the target number, an extra amount is required during the counting operation as compared with the conventional method. There is no need to do any kind of operation.
Therefore, there is an effect that not only the operator does not enter an erroneous set point or a set point percentage by key input, but also the counting operation can be efficiently performed.
