Abstract

PURPOSE:To provide a simple and exact wt. measurement and a measuring method for a noble metal for quantity measurement. CONSTITUTION:A lightweight noble metal is placed on a wt. measuring device 3 for measure to compare with the standard value by means of a personal computer. When the result meets the standard, the indiscrete value is displayed and cumulative arithmetic is done. When the result deviates from the standard, an attention is called by reversely displaying the indiscrete value and cumulative arithmetic is applied to the noble metal deviated from the standard to provide the halt state unless a specific key is pressed. A weighing key or the specific key is then pressed to allow the following measure. The above processes are then repeated. When the quantity has reached to specific quantity, all the data for the total noble metals are recorded.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a precious metal weighing method which is suitable for weighing and selecting particularly small weight items such as precious metal ornaments, coins and metal bars.

[0002]

2. Description of the Related Art Conventionally, in order to weigh the above-mentioned small weight products of precious metals, one by one is placed on a weighing machine to determine whether or not a standard value is appropriate.

According to this measuring method, it takes time and labor to measure and select, the workability is poor, and the reliability of the inspection accuracy is poor.

For this reason, various measuring methods and systems have been studied in consideration of workability and inspection accuracy, and recently, measured values are displayed on a printer and accumulated values are managed. However, further efficiency and simplification have been desired.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to provide a noble metal calibration method for simple and accurate weight measurement and quantity measurement.

[0006]

The precious metal weighing method of the present invention for solving the above-mentioned problems places a small weight precious metal product on a weighing machine and weighs it. When the value is within the standard, the measured value is displayed and cumulative calculation is performed.When the value is out of standard, the caution is indicated by the reverse display of the measured value and the cumulative calculation of the non-standard product is performed, and it is stopped unless a specific key is pressed. After that, the weighing key or the specific key is pressed to enable the next weighing, and the above steps are repeated thereafter, and when the designated quantity is reached, all the total data are recorded in the printer.

[0007]

According to the above-described precious metal weighing method of the present invention, when the weight of a small precious metal product is out of the standard, the interruption of the weighing is surely performed, and the abnormal state due to the reversal display of the weighing value is clarified and cautioned. , A specific key operation restarts weighing. Therefore, it is possible to prevent the small weight precious metal product having a nonstandard weight from being mixed with the small weight precious metal weight having a weight within the standard. In addition, quality information in lot units can be viewed in real time. Furthermore, the weighing result according to the standard setting can be automatically discriminated. In addition, the work can be grasped by displaying the quantity of small weight precious metal products within the standard weight.

EXAMPLE An example of the method for calibrating a noble metal according to the present invention will be described with reference to the drawings. FIG. 1 shows devices used in the present invention.
FIG. 2 shows a small precious metal product, and FIG. 3 shows a chart of the present invention. The operator turns on the personal computer 1, the printer 2, and the weight measuring device 3, and inputs various operating conditions (product name, standard weight, upper and lower limit values, lot number, measurement date) to the personal computer 1. Next, the precious metal small weight item 4 (100 g Au coin) is intermittently sequentially placed and placed on the weight measuring machine 3 for weighing. Then, the measured value and standard numerical value are checked, and when the value is within the standard, the measured value is displayed and cumulative calculation is performed on the screen of the PC 1, and when the value is out of the standard, the measured value is highlighted on the screen of the PC 1. At the same time, an alarm sound is emitted from the personal computer 1 to call attention and cumulative calculation of nonstandard products is performed. After that, the operator presses the weighing key as the next step when the value is within the standard, and the operator presses the specific key as the next step when the value is out of the standard to enable the next weighing. After that, the above steps are repeated, and when it is detected that the designated quantity has been reached, the quality information is input to the printer and the measurement record is printed.

According to the precious metal calibration method of this example, 10
When the weight of the 0 gAu coin is out of the standard, the interruption of the weighing is surely performed, the abnormal state is highlighted and the caution is urged by the reverse display of the weighing value, and the weighing is restarted by a specific key operation. Therefore, it is possible to prevent the Au coin having a nonstandard weight from being mixed into the 100 g Au coin having a standard weight. Also,
You can see quality information in lot units in real time. Furthermore, the weighing result according to the standard setting can be automatically discriminated. Further, the work can be grasped by displaying the number of Au coins having a weight within the standard.

[0010]

As described above, according to the precious metal calibration method of the present invention, when the weight of a small precious metal product is out of specification, the measurement is reliably interrupted and an abnormal state is clearly indicated. It is possible to prevent mixing into heavy goods.
In addition, quality information by lot can be viewed in real time. Furthermore, the weighing result according to the standard setting can be automatically discriminated.

FIG. 2 is a diagram showing a precious metal small weight product of the present invention.

FIG. 3 is a chart showing steps of the method for calibrating a small weight precious metal product of the present invention.

Claims (1)

[Claims] 1. A small precious metal product is placed on a weighing machine and weighed, and a personal computer checks the standard numerical value. If the value is within the standard, the measured value is displayed and cumulative calculation is performed. If the value is outside the range, the caution is displayed by reversing the display of the weighing value and the cumulative calculation of the nonstandard product is performed, and it will be in the stopped state unless the specific key is pressed, and then the weighing key or the specific key is pressed to start the next weighing. A method for calibrating precious metals, characterized in that the above steps are repeated, and when the designated quantity is reached, all data of the total number is recorded in a printer.
