Abstract:
A photo-fiber link glue control system (10) for accurately placing a pattern of glue on a sequential series of targets traveling with a conveyor (54) through the system (10). The system (10) includes an air reservoir (18) and a glue tank (24) for storing glue to be applied to the series of targets. A glue head (32) is connected to receive glue from the glue tank (24) for application to the series of targets. The lead and trailing edge of the target is detected by photo-eye sensors (44, 46) which generate a target position signal indicative of the sensed position. The pressure within the air reservoir (18) and glue tank (24) are monitored and a control device (36) stores a pattern in which the glue is to be applied to the target. Based upon the sensed pressure values, the sensed target position and the stored pattern, the control device (36) enables an air compressor (12) to receive air for delivery to the air reservoir (18) thus increasing the pressure therein and applying a pressure on the glue tank (24) causing glue to flow to the glue applicator (32) for placement on the target in accordance with the stored pattern.
