Optimizing method for auto-tuning of working parameters of automatic quantitative packing scale

Abstract

The invention discloses a method for automatically setting and optimizing working parameters of an automatic quantitative packaging scale, and relates to the field of automatic quantitative packaging scales. The method performs a feeding test of feeding at a slow speed throughout the whole process, and then conducts a feeding test at a high speed and then at a slow speed. In the feed test of the raw material, in the two feed tests, several key node data are obtained according to the obtained target weight and the stable duration of the slow feed, and the end weight of the fast feed can be realized according to the obtained key node data. The automatic setting and automatic optimization of the two important parameters, the end weight of the slow feed and the end weight of the slow feed, this automatic setting method eliminates the dependence on the technical level of the operator and the complexity of the material characteristics, and the accuracy and efficiency are relatively high. High; so that the automatic quantitative packaging scale can maximize its speed while meeting the accuracy requirements stipulated by the state; at the same time, it can automatically judge whether the entire parameter setting and optimization process is stable and reliable, and meets the trust conditions.

Description

technical field [0001] The invention relates to the field of automatic quantitative packaging scales, in particular to an automatic setting and optimization method for working parameters of the automatic quantitative packaging scales. Background technique [0002] In the actual use of the automatic quantitative packaging scale, the most important purpose is to make each package be accurately loaded to the target weight, and a classic quantitative weighing feeding process consists of two sub-processes: fast feeding process and Slow feed process. Among them, the speed of the automatic quantitative packaging scale is determined by the proportion of the weight of the material completed by the rapid feeding process in the entire target weight. For example, if each package is 25kg, then the rapid feeding process is completed after feeding 10kg or after feeding 15kg. Slow feeding, this has a great influence on the speed of automatic quantitative packaging scale. Obviously, if the...

[0003] As mentioned above, the speed and accuracy of the automatic quantitative packaging scale are mainly determined by the proportion of the fast feeding process and the slow feeding process, and the control of the proportion of the fast feeding process and the slow feeding process is mainly the end of the fast feeding Therefore, it is difficult to set and adjust these two parameters during the working process of the automatic quantitative packaging scale. At present, the engineer usually adjusts these two parameters, and the engineer’s The requirements for professionalism and work experience accumulation are relatively high, and it is greatly affected by human subjectivity, the control accuracy is not high, and it usually requires repeated debugging, which is cumbersome
