Problems solved by technology

In addition, if the item deviates from the conveyor belt, it will cause false positives and corrections, which will eventually cause the conveyor belt to deviate, so the stability is poor.

Embodiment Construction

[0042] Take single roller or trough belt conveyor as an example, such as figure 1 shown. Among them are belt conveyors (trough or straight, including basic configurations such as driving motors and rollers), laser scanner A, laser scanner B, DC regulated power supply C, DC regulated power supply D, serial port processor E, serial port processor F, Ethernet G, server H, host computer I, display screen J, sound and light alarm K, emergency stop device L, storage chip M, belt and scanner synchronous start switch N. Laser scanner A and laser scanner B are respectively located on the belt bracket next to the lower and upper rollers of the conveyor belt, and in the same plane as the conveyor belt, so that the laser scanner is perpendicular to the edge section of the belt to scan the sector area, and the scanning distance should be ensured The range should be greater than the belt thickness to obtain the lateral distance of the belt edge from the belt pulley edge support. Laser sca...

Abstract

The invention discloses a belt deviation alarm and emergency stop method for belt edge detection, which adopts a conveyor belt deviation detection system based on laser lateral scanning belt edge distance measurement, including laser scanner A, laser scanner B and the conveyor belt. In the same plane, it is used to obtain the lateral distance between the edge of the belt and the edge support of the belt pulley; the laser scanning data can be sent to the Ethernet by the serial port processor for remote transmission; the upper computer realizes the online belt running according to the measurement data of the laser scanner A and B Real-time calculation of the offset angle and offset during the deviation process; the sound and light alarm and emergency stop device make corresponding judgments after data processing by the host computer, and control the operation of the sound and light alarm and emergency stop device. The invention makes up for the current situation that there is no high-precision non-contact belt conveyor real-time deviation detection system in the field. The invention has the advantages of simple and convenient measurement, strong anti-interference ability, high detection precision and strong real-time performance, and is not affected by the external environment on the determination of material distribution.

Description

technical field [0001] The invention relates to a belt deviation alarm and emergency stop method for belt edge detection. Background technique [0002] Conveyor belts are widely used in industrial transportation. However, during the operation of the belt conveyor, the deviation of the conveyor belt often occurs, which not only causes material spillage or belt edge wear, but also causes the conveyor belt to break and burn. damage or even cause a fire. This will directly affect the service life of the conveyor belt, and even lead to the outage of the coal transportation line, affecting safe production and causing major economic losses. Therefore, timely and accurate detection of belt deviation is of great significance. Most of the belt deviation detection devices on the market today are contact detection devices. When the conveyor belt does not deviate, the edge of the conveyor belt does not contact the side rollers of the correction device, and the correction device remains...
