A REJECT-SYSTEM FOR TIIMPLATE WITH SURFACE DEFECTS

摘要

This system has the following characteristics: ID It has a detector able to classify tinplate with surface defects as well as detectors for thickness metering.(2) With regard to pin-holes, two devices called "shift resistors" follow the pin-holed sheet along the conveyors of the tinplate shear line, and check whether the sheet is classified and piled ("stacked") correctly. This is done by comparing two signals from the "shift resistor" and "sheet detector" located before the piler. If the pin-holed sheet does not arrive at the correct piler, an alarm alerts the operator.
