Coating production equipment distance measuring sensor failure calculation method and measuring device for coil diameter

Abstract

The invention discloses a roll diameter calculation method and a measuring device when a distance measuring sensor of a coating production equipment fails. A diameter calculation program, the value calculated by the program replaces the measured value of the ranging sensor. The invention can be used in coating production equipment when the distance measuring sensor is faulty, and the coil diameter calculation program is used instead of the distance measuring sensor to measure the coil diameter, and the fault can be found in time without the presence of technicians and the normal operation of the equipment can be ensured.

Description

technical field [0001] The invention belongs to the technical field of coating production equipment, and in particular relates to a coil diameter calculation method and a measuring device when a distance measuring sensor of the coating production equipment fails. Background technique [0002] Coating production equipment is commonly used in papermaking, printing, textile and other industrial fields. The key to its production is that the linear speed of the load driven by each motor must be consistent during the production process. However, when the coating equipment is running, the winding diameter The real-time changes will lead to changes in the unwinding line speed, which will directly affect the quality and production safety of the produced products. Common coating production equipment mainly includes two types: one is the equipment that realizes fine-tuning of the line speed according to the tension. This kind of equipment calculates too frequently and has hysteresis, w...

[0002] Coating production equipment is commonly used in papermaking, printing, textile and other industrial fields. The key to its production is that the rotational speed of the load driven by each motor must be consistent during the production process. However, when the coating equipment is running, the winding diameter The real-time change will lead to the change of the unwinding line speed, which will directly affect the quality and production safety of the produced products

Common coating production equipment mainly includes two types: one is the equipment that realizes fine-tuning of the line speed according to the tension. This kind of equipment calculates too frequently and has hysteresis, which cannot guarantee product quality; However, due to factors such as changes in the winding position, the distance sensor often fails and production is interrupted, resulting in economic losses
