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

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] Such as figure 1 Shown is a structural block diagram of an embodiment of an automatic counter for metallurgical rods. 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 .

[0026] The first counting pulse generating unit and the second counting pulse generating unit are photoelectric switches, Hall switches, magnetic reed switches commonl...

Abstract

An automatic metallurgical bar counter comprises 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 count processing unit. Count pulses generated by the first output pulse generating unit and the second output pulse generating unit are sent to the count processing unit for counting after narrow pulse interference in the count pulses are filtered by the first narrow pulse filtering unit and the second narrow pulse filtering unit respectively, and the count processing unit takes the maximum count value as the counting result of the automatic metallurgical bar counter. The automatic metallurgical bar counter can be applied to occasions in need of product counting on all kinds of bar production lines.

Description

technical field [0001] The invention relates to a metallurgical bar material counting device, in particular to an automatic bar material counter. Background technique [0002] The metallurgical bar counter is a commonly used equipment in the metallurgical industry. The bar is accurately counted online through the counter, which is convenient for real-time online display and control of the number of bars 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 counting error. Contents of the invention [0003] In order to solve the problems existing in the product counting of the existing metallurgical bar automatic production line, the present invention provides an automatic metallurgical bar counter, including a first counting pu...
