Coiling winding material synthetic sensor

Abstract

The present invention relates to a multi-signal output winding integrated sensor used for winding diameter real-time detection, linear speed real-time detection, and winding length real-time detection of a winding, etc. The prior sensor can not compatibly detect the winding diameter, the linear speed and the winding length. The present invention makes two rollers and orthogonal coding discs with the same specification coaxially arranged in parallel, the orthogonal coding discs are arranged with detecting teeth and detecting slots along the circumferential direction, the detecting teeth and the detecting slots on the two orthogonal coding discs are arranged staggeringly, the size of the staggered position is half of an detecting tooth; a groove shape photoelectric switch is arranged at the position corresponding to each orthogonal coding disc, the groove shape photoelectric switch is connected with a signal processing circuit board, and a Hall is connected with the signal processing circuit board through an aviation connecting piece. The structure of the present invention is simple, the detecting precision is high, the function of an output signal is various, and the next application and processing is simple, thus the present invention can be used widely in the processing and manufacturing process such as a variety of band materials, wire rods, tubular products, etc.

Description

technical field [0001] The present invention relates to a sensor, in particular to a comprehensive sensor for winding objects with multi-signal output such as real-time detection of winding diameter, real-time detection of line speed and real-time detection of winding length during the winding process of the winding object. It is suitable for the measurement and control of coil diameter, line speed and coil length during the processing and production of various strips, wires and plastic pipes. Background technique [0002] In the process of processing, production and winding of various strips, wires, and plastic pipes such as flexible packaging printing, plastic films, paper products, textiles, tapes, metal foil strips, wires and cables, and cables, roll diameter detection, Line speed detection, winding length measurement and other measurement and control are the basic requirements in the above-mentioned various productions, and it is hoped that the signal output by the sens...

AI Technical Summary

Problems solved by technology

The existing roll diameter sensors are mainly: one is the sensor based on the principle of ultrasonic distance measurement, which needs to be calibrated in different applications, the installation method is relatively strict, and the price is expensive, such as Japan NIRECO company, Germany P+F The company's products, etc.; the second is the mechanical swing arm by wheel type, which detects the swing angle of the swing arm through the potentiometer on the mechanical swing arm and then converts it into a winding diameter. There are problems such as complex mechanism and mechanical beating interference; the third is as a coil diameter detection module attached to a specific instrument or system (such as a domestic Emerson asynchronous motor inverter specially used for winding tension control)

In addition, the thickness integral method is also used, but in this method, the initial coil diameter and the thickness of each layer of the coil need to be set. Thickness will change due to force

In addition, there are also problems such as low vehicle speed for online speed detection and winding length measurement, and subsequent signal processing is not convenient enough.
