Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the external configuration of an electronic weighing device according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the electrical configuration of the same embodiment. In these figures, 1 controls each part of the device. CPU (Central Processing Unit), 2 and 3
Are scales, which constitute the weighing section 4, and are respectively selected to transfer the weighing signal corresponding to the weighing result to the CPU 1.

Reference numeral 5 denotes a display unit composed of a plasma display or the like for displaying data such as weight and unit weight, and displaying various states such as tare weight cancellation. Reference numeral 6 denotes an operation unit, which includes a touch panel 6a provided on the display unit 5, numeric keys and function keys 6b, and alphabet keys 6c. Of these, when the operator touches the key top display portion displayed on the display screen of the display portion 5 of the touch panel 6a, the item of the portion is input.

Further, in FIG. 2, reference numeral 7 denotes a ROM, which is composed of a control program area for controlling weighing processing, printing processing, display processing, data writing processing, and the like, and a table for storing character patterns. Reference numeral 8 denotes a RAM, a working area in which various flags and registers are secured, a preset data file 8a (see FIG. 3) for storing preset data, a total data file for storing total data, and a reservation It is composed of a reserved data file 8b (see FIG. 4) for storing data and a work record data file for storing work record data.

Further, in FIG. 1 and FIG. 2, reference numeral 9 is a printing unit, and when the operator presses one print key or the like of the function keys 6b, information relating to loading and unloading read out from the RAM 8 by the CPU 1 and the like. On the label or receipt. Further, 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 the electronic weighing device and a rotating rack (not shown), refer to the specification and drawings attached to the application of Japanese Patent Application No. 1-225548. In addition, reference numeral 11 is a buzzer for notifying that the count value is equal to the target number or exceeds the set point in a different manner when the count value becomes equal to the target number or exceeds the set point due to counting work. And a notification unit such as a lamp.

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, a CPU for counting articles
The operation of No. 1 will be described with reference to the flowchart of FIG. When the worker carries out the article unloading process by operating the touch panel 6a of the operation unit 6 or the function keys 6b, the electronic weighing device enters the unloading operation mode. As a result, the CPU 1 executes step S1 shown in FIG.
After reading the reservation data (article number and target quantity) stored at the top of the reservation file 8b shown in FIG. 4, the process proceeds to step S2.

In step S2, preset data (article number, article name, unit weight, set point percentage, shelf number) corresponding to the article number in the reservation data read out in step S1 is preset as shown in FIG. It is read from the data file 8a and displayed on the display unit 5 together with the reservation data (article number and target quantity) read in the process of step S1. Further, according to the rack number read from the preset data file 8a, a signal is sent to the carousel control unit 10 to move the target rack to the take-out position. Then, after turning on the lamp that points to the tray for storing the target article, the process proceeds to step S3.

In step S3, if the predetermined number is 10, the worker takes out 10 desired articles from the tray and places them on the scale 2 or 3. This allows
The weighing unit 4 weighs the weight of the article. Then step S
Go to 4. In step S4, the CPU 1 divides the weight of the article weighed in the weighing section 4 by the unit weight read in step S2, and then rounds the number after the decimal point of the division result. The number is displayed on the display unit 5 as a count value. Then, the process proceeds to step S5.

In step S5, the CPU 1 executes step S5.
It is compared whether or not the count value representing the number of articles counted in 4 is equal to the predetermined number 10. If the comparison result is "Yes", the process proceeds to step S6. In step S6, a buzzer sound is generated to notify that the article number of the reservation data read by the CPU 1 in the processing of step S1 matches the article placed on the scale 2 or 3.

On the other hand, if the comparison result in step S5 is "No", the process proceeds to step S7. Step S
7, the scale 2 or 3 in step S3
It is determined whether or not the articles placed on are different articles.
If the result of this determination is "Yes", the procedure returns to step S3, and the operator returns the article to the original tray. After that, when the correct article taken out from the correct tray by the operator is placed on the scale 2 or 3, the CPU
1 performs steps S3 to S5 described above. On the other hand, the result of the determination in step S7 is "NO", that is, the number of articles taken out from the tray is correct,
When the number is different from the predetermined number (during measurement work), the process proceeds to step S8.

In step S8, an appropriate number of the same articles as the articles placed on the scales 2 or 3 by the operator in step S3 are placed on the scales 2 or 3 by the operator. Then, the CPU 1 executes step S
Similar to the process performed in 4, the weight of the article weighed in the weighing unit 4 is divided by the unit weight read in step S2, and the result of the division is rounded to the right of the decimal point. That is, the number of articles is displayed on the display unit 5 as a count value.

When the count value reaches the set point value (= target number × set point percentage / 100), thereafter, count value <target number, count value = target value,
Buzzer with different tone is sounded according to each of count value> target number. Then, the operation of step S8 is repeated until the count value becomes equal to the target number. Next, step S
Proceed to 9.

In step S9, it is determined whether or not there is a key input by the operator to advance to the next reservation data of the reservation file 8b shown in FIG. This determination is, for example, a key [NEX] for instructing the operator to read the next reservation data on the touch panel 6a of the operation unit 6.
This is performed by determining whether the T] key has been pressed.
If the result of this determination is "No", the process returns to step S3, and the process of counting the articles is performed by repeating the processes of steps S3 to S8 described above. On the other hand, when the determination result is “Yes”, the process proceeds to step S10.

In step S10, the above-mentioned step S
It is determined whether or not the item counted in the processing of 3 to step S8 is related to the last reservation data. This determination 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 for processing reservation data is provided, and the counter is cleared before the processing of step S1.
Each time the processing of one item is completed, the value of the counter is incremented by 1
It is incremented only and it is determined whether or not the value of the counter at the end of all the reservation data has become equal to a preset maximum value. Then, step S10
When the result of the determination is “No”, the process returns to step S1 and the processes of steps S1 to S10 described above are repeated. On the other hand, the determination result of step S10 is "Yes".
In other words, that is, the above-mentioned steps S3 to S
If the item counted in the process of 8 is related to the last reservation data, the series of operations is ended.
