Conveyor lubricating and washing apparatus

In a conveyor apparatus having a conveyor belt and a motor selectively enabled by motor control means coupled to input power lines for driving said belt along a slider means and further having first lubricating fluid dispensing means for directing a lubricating mixture of detergent and water at said belt for reducing friction between said conveyor belt and said slider means and second washing fluid dispensing means for directing a washing mixture of detergent and water at said belt for cleansing said belt, each of said fluid dispensing means being coupled to water supply means by respective first and second water lines and to a detergent reservoir, control apparatus comprising:

• first electrically controlled valve means interposed in said first water line for controlling the flow of water through said first water line from said water supply means to said first fluid dispensing means;
• second electrically controlled valve means interposed in said second water line for controlling the flow of water through said second water line from said water supply means to said second fluid dispensing means;
• pump means having input means coupled to said detergent reservoir and output means coupled to said first and second water lines for delivering detergent to said water lines;
• master switch means coupled to said motor control means and to said first electrically controlled valve means and said pump means, said master switch means being actuable to a first switch position to energize said motor control means and enable said conveyor motor and to enable said pump means and open said first electrically controlled valve means to allow water and detergent to be dispensed from said first fluid dispensing means to lubricate said conveyor belt;
• switch means having first normally open circuit means coupled to said motor control means and second normally open circuit means coupled to said second electrically controlled valve means and said pump means;
• and
• wash timer means coupled to said master switch means and said switch means for closing said first and second normally open circuits of said switch means for a predetermined time interval after said master switch means is switched form the first switch position to a second switch position,
• said switch means opening said second electrically controlled valve means and energizing said pump means during said predetermined time interval responsive to said wash timer means to allow water and detergent to be dispensed from said second fluid dispensing means to wash said conveyor belt and maintaining said motor control means energized to enable said motor to move said conveyor belt past said second fluid dispensing means.
