Counting device and counting method for metallurgy bars

Abstract

The invention discloses a counting device and a counting method for metallurgy bars, and belongs to the technical field of bar counting equipment. The counting device and the counting method are used for accurately counting the metallurgy bars. According to the counting device and the counting method, four sections of transmission chains are adopted to buffer bar layers, and through differential steel bar splitting and layer stepping of the transmission chains, the bars are separated one by one and stacking of the bar layers are effectively prevented. Two groups of photoelectric counting gratings mounted at different positions are utilized to count the bars, and the maximum value of counting values of the photoelectric counting gratings is taken as a counting result, so that the problem that the value of the counting result is small due to crossing of the bars is solved; influences of accumulated errors of the photoelectric counting gratings on the whole bundle of counting results are reduced by a layer correction method, and a correction method in which a small counting value is taken as a layer counting result if the small counting value of layer counting of the photoelectric counting gratings is equal to the bar number of the bar layers is adopted, so that accuracy of bar counting can be further improved. Through mutual correction of the two counters, counting accuracy is greatly improved, and the counting device has the advantages of high counting accuracy and simple structure.

Description

technical field [0001] The invention relates to a device for counting metallurgical rods and a method for using the device, belonging to the technical field of rod counting equipment. Background technique [0002] In the metallurgical bar production process, counting bars is an important part of the production process. A large number of automatic counting devices and methods have been adopted at present, and these automatic counting devices and methods include a single grating counting device and method, a grating and an encoder combined counting device and method, and the like. However, in actual operation, automatic and accurate counting of bars has always been a difficult point. The single grating counting device and method seriously affect the counting accuracy due to the practical problems of stacking and crossing bars. The degree of tightness, the rolling of the bars on the chain, and the movement of the bars against each other make the number of pulses recorded b...

Problems solved by technology

However, in actual operation, automatic and accurate counting of bars has always been a difficult point. The single grating counting device and method seriously affect the counting accuracy due to the practical problems of stacking and crossing bars. The degree of tightness, the rolling of the bars on the chain, and the factors of the extrusion and movement of the bars cause the number of pulses recorded by the encoder to not truly reflect the actual diameter of the bars, and there are obvious defects in practical applications.

In addition to the above-mentioned counting devices and methods, with the rise of machine vision technology in recent years, there have also been some attempts in the field of bar counting, but this technology has high requirements for the stability of on-site ambient light, complex calculation methods and high investment costs. not yet widely used
