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.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] Such as figure 1 Shown is a structural block diagram of an embodiment of the automatic steel counting device for the bar production line. The first counting pulse generating unit 101 outputs the first initial pulse M1, and the first narrow pulse filtering unit 201 performs narrow pulse filtering on M1 to obtain the first counting pulse N1 after the interference pulse is filtered out; the second counting pulse generating unit 102 outputs The second initial pulse M2 is narrow pulse filtered by the second narrow pulse filtering unit 202 to obtain the second count pulse N2 after filtering out the interference pulse. The first counting pulse N1 and the second counting pulse N2 are sent to the counting processing unit 301 .

[0023] The first counting pulse generating unit and the second counting pulse generating unit are photoelectric switches, Hall switches, magnetic r...

Abstract

An automatic steel counting device for steel separation in a bar production line, comprising a first output pulse generating unit, a second output pulse generating unit, a first narrow pulse filtering unit, a second narrow pulse filtering unit, and a counting processing unit. The counting pulses generated by the first output pulse generating unit and the second output pulse generating unit are respectively sent to the counting processing unit for counting after the narrow pulse interference is filtered out by the first narrow pulse filtering unit and the second narrow pulse filtering unit, and the counting processing unit takes The one with the larger count value is taken as the counting result of the device. The device also includes a first transmission speed conversion unit and a second transmission speed conversion unit. The maximum width of the narrow pulse to be filtered can be adaptively changed following the transmission speed of the rod product, and can be adjusted by changing circuit parameters. The device can be applied in various bar production lines, such as automatic steel counting for steel division, where the number of products needs to be counted.

Description

technical field [0001] The invention relates to a metallurgical bar counting device, in particular to an automatic steel counting device for separating steel in a bar production line. Background technique [0002] The metallurgical bar rolling piece counting device is a commonly used equipment in the metallurgical industry. For example, the steel counting and dividing platform of the iron and steel plant counts the bars online through the counting device, which is convenient for automatic steel dividing. 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. In addition, the transmission speed of bar products is different, and the width of narrow pulse interference signals is also different. Contents of the invention [0003] In order to sol...
