Bar rolled piece counting method

Abstract

The invention discloses a bar rolled piece counting method comprising the steps of separately installing count detection devices of a first count pulse generation unit and a second count pulse generation unit at the different section chain of bar transmission or the different positions of the same section chain of bar transmission; separately performing narrow pulse filtering and counting on pulsesignals output by the first count pulse generation unit and the pulse signals output by the second count pulse generation unit, and using the relatively large count value as an automatic counting result of a bar production line, wherein the narrow pulse filtering separately performed on the pulse signals output by the first count pulse generation unit and the pulse signals output by the second count pulse generation unit is implemented by a narrow pulse filtering unit, and the narrow pulse width filtered by the narrow pulse filtering unit is controlled by a bar transmission speed. The counting method can be applied to occasions where the quantity of products needs to be counted on various bar production lines.

Description

[0001] The patent application for this invention is a divisional application, the original application number is 201610420866.7, the application date is June 15, 2016, and the invention name is a bar rolling piece counting device. technical field [0002] The invention relates to a metallurgical bar material counting device and method, in particular to a bar material rolling piece counting method. Background technique [0003] The metallurgical bar rolling counting device is a commonly used equipment in the metallurgical industry. The bar is accurately counted online through the counting device, which is convenient for real-time online display and control of the bar count in the metallurgical process. Due to the slipping of the bar chain, the rolling of the bar, the vibration of the bar, the overlapping of the bar, etc., the edge of the counting pulse signal generated by the detection device has a jitter pulse, that is, a narrow pulse interference signal, resulting in a count...

AI Technical Summary

Problems solved by technology

Due to the slipping of the bar chain, the rolling of the bar, the vibration of the bar, the overlapping of the bar, etc., the edge of the counting pulse signal generated by the detection device has a jitter pulse, that is, a narrow pulse interference signal, resulting in a counting error.
