Automatic control system for multilayer uncoiler

Abstract

The invention discloses an automatic control system for a multilayer uncoiler, which comprises a lifting motor upper limit position sensor, a first tension roller upper limit position sensor, a second tension roller upper limit position sensor, a first tension roller lower limit position sensor, a second tension roller lower limit position sensor, a lifting motor lower limit position sensor, an uncoiling lifting motor, a disk uncoiling motor, a reflector, a controller, a counter, an input / output interface and a photoelectric sensor, wherein the sensors are sequentially arranged and used for respectively detecting running position signals of tension rollers. The automatic control system for the multilayer uncoiler can be used for automatically changing laps of the uncoiler, and has the advantages that labor and time are saved, continuous production of a production line is ensured, full-automatic production can be realized, complexity and difficulty of manual operation are eliminated, the production line can run more reliably, owing to real-time online detection and correction, a steel strip can be tensioned, the speed is matched with the speed of a front unit, and the steel strip is prevented from being scratched due to excessively loosening.

Description

technical field [0001] The invention belongs to the field of industrial control, in particular to an automatic control system for a multi-layer uncoiler applied in a welded pipe production line. Background technique [0002] The uncoiler is a special equipment for metal plate leveling. It is used for leveling steel plates and uneven plates. It can be composed of uncoiling, leveling, shearing production lines and other plate product production lines according to relevant configurations. It is suitable for machinery, vehicles, metal products, household appliances, steel structures, decoration and other industries. [0003] At present, the uncoilers used in the welded pipe production line are single-layer uncoilers or need to be used in conjunction with loopers. They use manual methods to control coil change, which has the following disadvantages and deficiencies: [0004] 1. The coils are changed frequently, the labor intensity is high, and the degree of automation is low, so...
