BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic weighing apparatus such as an electronic counter for measuring the total weight of articles and calculating and displaying the number of articles based on the total weight and the 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 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 Patent Laid-Open 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 measurement, 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 when counting objects with large unit weights or large shapes, or when the target number is large, set a large set point, and on the contrary, counting objects with small unit weights or small shapes. This is because the set point must be set small when the target number is small.

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

First calculating means for calculating a set point which is a value in the vicinity of the target number based on the number of pieces and the set point percentage, weighing means for measuring the total weight of the article, the total weight and the unit A second calculating means for calculating the number of the articles based on the weight, and an informing means for informing that when the number is larger than the set point. It is characterized in Rukoto.

According to a second aspect of the present invention, in the first aspect of the present invention, the notifying means is different from the case where the number is larger than the set point when the number is equal to the target number, The feature is that it is notified. The invention according to claim 3 is the invention according to claim 1 or 2, wherein the notifying unit is configured such that when the number is greater than the target number, when the number is greater than the set point, or when the number is the target. The feature is that the fact is notified in a manner different from the case where the number is equal.

[0013]

According to the first aspect of the present invention, the reading means reads the target quantity from the first storage means and the corresponding unit weight and set point percentage from the second storage means for each article. The first calculation means calculates a 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 means calculates the number of articles based on the total weight and the unit weight, so that the notifying means notifies that when the number is larger than the set point.

And a work record data file for storing work record data.

Further, in FIGS. 1 and 2, reference numeral 9 denotes a printing unit, which is an operator pressing one print key or the like of the function keys 6b to obtain information about loading / unloading from the RAM 8 by the CPU 1. 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 to preset data file 8a shown in FIG. 3 and FIG. Preset data and reservation data are stored in advance in the reservation file 8b shown in FIG.

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 device to the leaving operation mode, the CPU 1 proceeds to step SP1 shown in FIG. 5 and stores the reservation file 8b shown in FIG. Reservation data stored at the top (article number and target quantity)
After reading, the process proceeds to step SP2.

In step SP2, preset data (product name, unit weight and set point percentage) 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. , The unit weight, and the article number and the target number read out in the process of step SP1 are displayed on the display unit 5.
After that, the process proceeds to step SP3.

At step SP3, a set point is calculated based on the following equation, and then the process proceeds to step SP4. Set point = target number x set point percentage ÷ 1
00 At step SP4, when the worker takes out the article having the product name displayed on the display section 5 from the tray notified by the indicator light of the rotating rack (not shown) and places it on the scale 2 or 3 of the weighing section 4. , The CPU 1 divides the weight of the article measured by the weighing unit 4 by the unit weight read in the process of step SP2, then rounds down the number after the decimal point of the division result and calculates the result. After the numerical value is displayed on the display unit 5, the process proceeds to step SP5.

In step SP5, it is determined whether or not the count value obtained in the process of step SP4 is equal to or more than the set point obtained in the process of step SP3. If the result of this determination is "YES", the flow proceeds to step SP6. In step SP6, the count value obtained in the process of step SP4 is compared with the target number read in the process of step SP1. If it is determined that the count value is smaller than the target number, the process proceeds to step SP7. In step SP7, 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, when it is determined in step SP6 that the count value is equal to the target number, step S6
Proceed to P8. In step SP8, a buzzer having a tone color different from the buzzer of step SP7 of the notification unit 11 is sounded, and then the process proceeds to step SP10.

When it is determined in step SP6 that the count value is larger than the target number, step SP
Proceed to 9. In step SP9, a buzzer having a tone color different from those of steps SP7 and SP8 of the notification unit 11 is sounded, and then the process proceeds to step SP10. Also,
When the determination result of step SP5 is "NO", that is, the count value obtained in the processing of step SP4 is the step S
Even if it is smaller than the set point obtained in the process of P3, 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 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. If the result of this determination is "NO", the flow returns to step SP4 and the above-mentioned step SP4 ~
The processing of SP9 is repeated. Then, the worker repeats the placement of the article having the product name displayed on the display section 5 on the scale 2 or 3 of the weighing section 4 to thereby perform step SP6.
It is determined that the count value and the target number are equal in the process of step S8, and the fact is notified in the process of step SP8. Therefore, when the operator presses the [NEXT] key on the touch panel 6a of the operation unit 6, the step SP10
The result of the determination is "YES", and the CPU 1 proceeds to step SP11.

In step SP11, it is determined whether or not the article counted in the processing in steps SP4 to SP9 is related 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, if the determination result of step SP11 is "YES", that is, step SP4 described above.
If the item counted in the processing of SP9 is related to the last reservation data, the series of operations is ended.

[0028]

As described above, according to the present invention,
This has the effect of automatically setting set points according to the items to be counted and the target number. Since the set point percentage for each article is set in advance in the storage means, there is no need to perform extra operations during the counting operation as compared with the conventional method. Therefore, there is an effect that the article loading / unloading work can be efficiently performed by the work reservation.
