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 a speed-adaptive automatic counting device for a threaded steel production line. The counting pulse generating unit 101 outputs an initial pulse M1, and the narrow pulse filtering unit 201 performs narrow pulse filtering on M1 to obtain the counting pulse N1 after filtering out the interference pulse. The counting pulse N1 is sent to the counting processing unit 301, and the counting processing unit 301 counts N1.

[0026] The counting pulse generation unit is a photoelectric switch, Hall switch, magnetic reed switch commonly used in the production line, or a counting detection device such as an inductive proximity switch or a capacitive proximity switch. Output an initial pulse signal when a bar passes through the rebar production line. The initial pulse is the count pulse without filtering ...

Abstract

Provided is a thread steel production line speed self-adaption automatic counting device, comprising an output pulse generating unit, a narrow pulse filtering unit and a counting treatment unit. The narrow pulse filtering unit filters the narrow pulse interference of the counting pulses generated by the output pulse generating unit, and then the counting pulses are sent to the counting treatment unit; the counting treatment unit employs counting values as counting results of the counting device. The thread steel production line speed self-adaption automatic counting device also comprises a transmission speed transformation unit, and the largest width of narrow pulses to be filtered can change adaptively with a bar product transmission speed, and can adjust through changing circuit parameters. The automatic counting device can be applied to various bar production lines such as thread steel production lines which require product counting.

Description

technical field [0001] The invention relates to a metallurgical bar material counting device, in particular to an automatic speed self-adaptive counting device for a threaded steel production line. Background technique [0002] Metallurgical bar automatic counting device is a commonly used equipment in the metallurgical industry such as rebar production. The bar is accurately counted online through the counting device, which is convenient for real-time online display and control of the number of bars in the metallurgical process. Due to reasons such as the chain slipping of the conveying bar, the rolling of the bar, and the vibration of the bar, 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 ...
