Novel length measuring system

Abstract

The invention discloses a novel length measuring system. The novel length measuring system is characterized by comprising a coder detection unit, a transmission unit, a PLC control unit and a human-machine interface HMI, wherein the coder detection unit measures the transmission length of a to-be-detected object strip plate, the transmission unit is arranged between the PLC control unit and the human-machine interface HMI, and the coder detection unit is mainly composed of a coder which is mounted at the shaft end of a main motor, and synchronously rotates with the main motor. The system can automatically measure the length of the strip plate and locate the strip plate in quality inspection. When a hot rolled strip plate which is annealed and acid-pickled is conveyed and transported to a quality inspection table, if a quality inspection person finds surface defects or other quality problems, the quality inspection person will press down a stop button and confirm the surface quality problems, and meanwhile, a PLC system calculates the length distance from the surface defect part to the head of the strip plate and the length distance is stored and displayed in an industrial personnel computer.

Description

technical field [0001] The invention relates to a novel length measuring system, which belongs to the technical field of quality inspection structural components. Background technique [0002] At present, the length measuring device in the strip quality inspection is the length measuring wheel. The main principle is to use the pulley to contact the strip to generate rotation, and the length of the strip can be measured by measuring the number of rotations. The length measuring wheel itself is measured by the circle. The unit error is large, and the length measuring wheel and the strip are easy to slip or have poor contact, which makes the length measurement more inaccurate. In addition, the rotating shaft is severely worn during use, and the failure rate is very high. Therefore, there is an urgent need for a new technical solution to solve the problems in the prior art. Contents of the invention [0003] The present invention aims at the technical problems existing in the...
