There are standard weights for management used in various manufacturing industries, etc. and standard weights with a calibration certificate (with JCSS logo mark) of an accredited company for calibrating them.

され精度（不確かさ）は悪くなる。また標準分銅は使用
により、磨耗、キズ、汚染等でその校正値が変化するの
で定期校正が必要である。[0004] If a higher-order standard weight obtained by calibrating a standard weight and a higher-order standard weight are traced one after another, a kilogram prototype is reached. Since the prototype only shows 1 kg, it is necessary to scale the mass to obtain an arbitrary mass value. For this reason, the calibration of the weight and double weight of the assembled weight is performed.
This is called the setting of the national mass standard. Based on this, the lower standard weight is calibrated, and the mass standard is supplied in Japan. The lower the standard weight, the lower the accuracy of measurement (error uncertainty) due to the added measurement error. In addition, the calibration value changes due to wear, scratches, contamination and the like due to the use of the standard weight, so periodic calibration is required.

は計り知れない。[0005] The higher the accuracy of the calibration of the standard weight, the higher the skill and the longer the labor required. In particular, the calibration by the volume / multiplier method used for setting the national standard is a rational calibration method with high accuracy, consistency, and accuracy (uncertainty) evaluation. However, it requires advanced technology based on long experience and is not common. If the calibration of these various standard weights can be automated, the range of use is wide and the benefits are incalculable.

ために自動化が必要とされている。The standard weight has a mass change due to a number of uses and requires periodic calibration to keep it within a tolerance range. In recent years, the amount of calibration work has increased,
The required accuracy has also been improved. In order to cope with this, the necessity of the calibration by the quantity / double method, which can be calibrated more accurately than the equivalent calibration, has been increasing. However, these tasks require a lot of experience and a high degree of skill and a lot of labor as described above. Automation is needed to save labor and streamline calibration work.

This is the development of a device that is automatically controlled.

化によりこれらの問題点を一挙に解決する。[0008] The weight / double calibration method is based on the understanding of calibration theory including the evaluation of uncertainty (accuracy) of calibration, the technique of installing a plurality of weights on a weighing dish to minimize the deviation error, and the technique of handling weights. It has required advanced technology based on long experience. However, there are many problems such as a mistake in the handling of weights, such as a mistake in weights having the same nominal value. Automation solves these problems at once.

環状の標準分銅を内蔵した本装置を開発した。The first problem is that it is very difficult to automate the calibration of the weight and the double weight in a normal weight shape (straight cylinder). The purpose is to change the shape of the built-in standard weight so that the weight can be arbitrarily added to and removed from the weighing pan by the weight adding and removing device, and to realize the calibration of the weight and the double weight. To realize these, we have developed this device with a built-in annular standard weight.

At the time of measurement of each of the measured values a 1 to a 9 , the built-in hanging weight is indicated by + and the built-in hanging weight mechanism 18 is operated.
With the built-in weights for hanging weights placed on the weighing pan 31, the built-in standard weight adding / removing mechanism 17 is operated.
The internal standard weight indicated by + was measured by the weighing unit 1, and the internal standard weight indicated by − was measured by the weighing unit 1.

Based on the calibration value of kg and the data on the measured values a 1 to a 2 , a calculation process based on the least squares method is performed in the personal computer 2, and the calibration value of each built-in standard weight and the accuracy (uncertainty) of the calibration value Get. As a result, the built-in weight can be made a consistent standard weight with an absolute value by using the external standard weight of 1 kg, and the built-in standard weight and other external built-in standard weights (500 g, 200 g, and 100 g) can be obtained. Can be checked / evaluated for the quantity calibration.

の開発により分量・倍量校正の自動化が可能になった。If the weighing is further reduced by an order of magnitude with the standard of 100 g being used, a quantity calibration of the order of 10 g can be performed. Similarly, if you reduce the digit, you can calibrate the amount up to 1 mg,
Standard settings can be made. Also, if the combination measurement for double weight is performed with 100 g as standard, double weight calibration can be performed, and 200 g,
500g and 1kg can be priced. That is, weigh 10k

Calibration for double weight of kg, 5 kg and 10 kg is possible. The development of this device has made it possible to automate the dosing / doubling calibration.

る。The above is the measurement for the calibration of the internal standard weight. The test weight is placed on the external standard balance plate 47 instead of the external standard weight, and the internal standard weight 3 is measured.
By performing the equivalent comparison measurement, the equivalent weight of the test weight can be calibrated. That is, it functions as an automatic weight calibration device.

Needless to say, there are various modes.

できる。Since the present invention has the above-described configuration, it exhibits the following effects. Since the high-precision weight calibration of the internal standard weight can be automatically performed, a high-precision internal standard weight can be easily obtained without requiring advanced technology. The calibration work of the test weight based on this can be realized only by setting the weight to the load exchange device without any labor.

理化に寄与できる。In addition, since the measurement is automatic, the measurement can be performed at night when the measurement environment is good, so that the accuracy can be improved. In order to avoid a large number of times of use of the standard weight, a company such as an accredited company which performs calibration work needs to transfer a value to an inspection standard used every day and use it. When using this device, the built-in weight can be used as an inspection standard, so self-calibration can be performed at an arbitrary cycle, the number of times the standard weight is used can be reduced, and the calibration cycle can be extended by a higher-level organization. It can contribute to labor saving and rationalization.

Even if the weights are not the same nominal value, it is convenient that the equivalent calibration with the same built-in standard weight can be performed.

が済むという可能性を含んだ装置の開発である。Since this device has a built-in standard weight and is not directly touched by the measurer, it also contributes to improving the maintenance of calibration values, such as not causing human error, and has no advanced technology. Can be operated by humans. Extremely speaking, if the user learns the setting of the test weight and the simple operation method, the apparatus automatically performs calibration and issues a certificate. In the future, we will develop a system that includes the possibility that the standard supply will be completed by distributing only the reference value of 1 kg and the calibration weight.
