A control system for a film transport vehicle in a film production line

Abstract

The invention provides a film production line film transport vehicle control system. The film production line film transport vehicle control system includes an automatic control system and an emergency control system, wherein the automatic control system comprises: a) an input signal acquisition part, b) a logic control part, and c) a drive part; and the emergency control system comprises: an emergency operating system and an emergency drive system For the film production line film transport vehicle control system, a vehicle body action executing part includes: A) a translation motor for driving the vehicle body to move back and forth along the track, B) a hydraulic motor for driving carriers at two ends of the film transport vehicle to lift, and C) a hydraulic solenoid valve for removingthe hydraulic pressure to lower the carriers at two ends of the film transport vehicle. The film transport vehicle controlled by the film production line film transport vehicle control system has theadvantages of being safe and reliable, being stable in action, being accurate in positioning, and being able to guarantee continuous operation of the production line.

Description

technical field [0001] The invention relates to a film transport vehicle used in a film production line, in particular to a film transport vehicle control system for a film production line. Background technique [0002] Biaxial stretching is a commonly used film production method. The biaxial stretching film production line is an assembly line composed of various equipment systems, including: drying system, extrusion system, casting system, longitudinal stretching system, transverse stretching system, traction Roller station, winding station, etc. The final produced film is wound on the steel coil core, and the steel coil core is placed on the two alternately working winding arms of the winding station, and the large film roll weighing 2 tons (the steel coil core is wound with a certain length) The film) is transported out from the winding arm of the unloading position and the round-trip transportation of the empty steel coil core to the winding arm of the unloading positio...

AI Technical Summary

Problems solved by technology

1. The film production line has a high degree of purification, so the film transport vehicle is placed outside the rolling shutter door of the winding station. The film transport vehicle can only enter and exit after the rolling shutter door is opened, otherwise the film transport vehicle will damage the rolling shutter door; 2. The unloading position of the winding station is rewinding arm The film transport vehicle can only enter and exit after the chuck is opened, otherwise it will cause the film transport vehicle to collide with the winding arm; 3. The film transport vehicle transports a large film roll weighing 2 tons or a steel coil core weighing 1 ton. The film transport vehicle runs stably and has precise positioning; 4. The film production line is a continuous assembly line. If the film transport vehicle breaks down and cannot transport the large film rolls and empty steel coil cores in time, it will inevitably lead to the shutdown of the production line
