SINGLE CULLING MECHANISM FOR USE WITH MACHINE VISON ON PRODUCTION LINE

摘要

A machine vision system for use in a high speed production system, such as disposable diaper manufacture, makes it possible to reject only single defective products as part of a single cull operation. To achieve single cull capability, a nondeterministic zone in which a reject signal from a relatively asynchronous machine vision system is input to a reject gate control and activation system is avoided. This machine vision system reject signal is also delayed relative to a camera trigger signal by a time or position delay in addition to shift register delays dictated by system parameters.
