Embodiment Construction
[0048] In order to solve the problem that the steel mill adjusts the speed difference between different transmission chains mainly based on the current number of bars, which will affect the subsequent bar counting problem, the application discloses a method for bar counting through the following embodiments The transmission mode control method and device of the chain bed.
[0049] First, combine figure 1The application scenarios of the embodiments of the present application are described. Before the steel mill bundles and packs the bars, the bars 1 are driven by the chain bed 2 and enter the counting area of the counting device 4, wherein the counting device 4 is equipped with a visual camera for collecting images of the end faces of the bars.
[0050] In practical applications, the chain bed includes at least three transmission chains, figure 1 The chain bed 2 shown in the figure includes four transmission chains: a first transmission chain 21 , a second transmission chai...

The invention relates to the technical field of bar counting, and discloses a chain bed conveying mode control method and device for bar counting. In the control method, by obtaining a current bar adhesion density value, a current conveying mode of a chain bed is set, wherein the current bar adhesion density value is within the current preset time interval, the quantity of bars overlapping and crossing on a first section of conveying chain occurs, the current conveying mode is one of multiple preset conveying modes, and each preset conveying mode is set in advance according to the total numberof sections of conveying chains of the chain bed. According to the chain bed conveying mode control method and device for bar counting, based on the current bar adhesion density value, the conveyingmode of the chain bed is controlled, the speed difference between different conveying chains is adjusted, no matter how many bars on the chain bed is, the quantity of bars which are overlapped ad crossed can be effectively decreased, and the subsequent bar counting accuracy is improved.
Description
technical field [0001] The present application relates to the technical field of bar counting, and in particular to a method and device for controlling a chain bed transmission mode applied to bar counting. Background technique [0002] Before the steel mills pack the bars according to the specified count, they need to count the bars. At present, many steel mills have adopted the visual inspection method for counting. When the visual detection method is used for counting, the image of the end face of the rod collected by the visual camera is processed to identify the contour of the end face of the rod, and then the counting is realized. [0003] During the counting process, the bars enter the counting area driven by the chain bed. However, the bars tend to overlap and cross on the chain bed, which leads to sticking of the end face of the bar in the image of the end face of the bar collected by the visual camera, making it difficult to distinguish the outline of the end face...
