Abstract:
A photo-fiber link glue control system for accurately placing a pattern of glue on a sequential series of targets, each target having a lead and trailing edge, traveling with a conveyor through said system, said photo-fiber link glue control system comprising:a) air compression means;b) glue supply means connected to said air compression means for storing glue to be applied to the series of targets;c) glue head means for receiving glue from said glue supply means and applying the glue to the series of targets;d) first photo-eye sensor means for detecting the lead and trailing edge of the target and generating a target position signal based upon the detection;e) pressure sensor means for sensing a pressure within said air compression means and glue supply means and generating a pressure signal indicative of the sensed pressures;f) control means for storing a pattern for the application of glue to the target, said control means being connected to receive said position signal from said first photo-eye sensor and said pressure signal from said pressure sensor means, wherein said control means determines a position of the target on the conveyor based upon the position signal and controls said pressure within said air compression means to supply air to said glue supply means thereby increasing pressure within said glue supply means and causing glue to flow from said glue supply means to said glue head means for placement on the target in accordance with the stored pattern and said determined position of said target;g) a second photo-eye sensor means connected to said control means for detecting the trailing and leading edges of the target for controlling the application of air through said glue head means to clean said glue head means when the target is not positioned in the glue application area and generating a glue prevention signal to prevent glue from being delivered to said glue head means upon receipt of said glue prevention signal.
