Title: Timing control system
Inventor: GIBSON DONALD FRANK
IPC: B05B12/12
Filed: 1985-01-10
Abstract: A system for use in automatic spray booths controls the operation of guns 16, 18 in response to sensor 54 detecting objects to be sprayed upstream of the booth and sensor 60 detecting the speed of a track conveying the objects to the booth. As shown whilst an object is passing sensor 54, pulses are clocked into register 74 via switch 80. Whilst the track is moving these pulses are shifted through the register. The guns 16, 18 are connected to outputs corresponding to their distance from the sensor 54, thus they are energised as the object reaches them. Timers 96 permit the guns to be started and spray stabilised before an object reaches them. An auxiliary spray gun can be controlled for a set period determined by timer 110 and initiated by logic 114. <IMAGE>
