High-efficiency and precise online quality calibration system

Abstract

The invention provides a high-efficiency and precise online quality calibration system, mainly consisting of an online quality calibration controller (5), a position detecting device and two sets of quality detecting devices. The online quality calibration controller consists of a positioning control module (15), a switching value input module (16), an analog input module (6) and a CPU, and the interfaces of all the modules are connected with the CPU through a substrate; each set of quality detecting device is provided with a weighting sensor, a quality detecting platform, and a bottle taking grip, a bottle taking live spindle and a spindle lifting mechanism which are all controlled by a servo motion controller; after the electric signals of the position detecting device and the weighting sensors of the two sets of quality detecting devices are processed by the online qualtiy calibration controller, actual measurement quality signals and error signals are output and online quality calibration is conducted on the filling quantity of a quantitative filling system. The system solves the online quality calibration problem of filling liquid-state products, and has high efficiency and precision with the calibration precision reaching 0.01g.

Description

technical field [0001] The invention relates to an on-line mass calibration system, in particular to an efficient and accurate on-line mass calibration system used in liquid filling fields such as chemical industry, food, and medicine. Background technique [0002] In chemical industry, food, medicine and other industries, many products in liquid state are shipped in the form of bottles (barrels), and the filled liquid needs to be filled quantitatively. In the prior art, quantitative filling cams or quantitative filling pumps are mostly used to determine the filling amount, but this quantitative method relies on the traditional mechanical structure accuracy, the quantitative accuracy is too poor, and the filling pass rate is low. The waste of liquid filling is enormous. At present, there is also a metering system to control the filling of liquid products. Most of the methods used are to stop the filling immediately after the metering system detects that the filling reaches ...

In the prior art, quantitative filling cams or quantitative filling pumps are mostly used to determine the filling amount, but this quantitative method relies on the traditional mechanical structure accuracy, the quantitative accuracy is too poor, and the filling pass rate is low. The waste of liquid filling is huge

At present, there is also a metering system to control the filling of liquid products. Most of the methods used are to stop the filling immediately after the metering system detects that the filling reaches the set filling amount during the filling process. However, this quantitative method ensures that the liquid filled products and The accuracy of the overall weight of the filled container cannot be accurate for the net weight of the liquid product, and the accuracy of the quality of the filled container also affects the accuracy of the filling of the liquid product
