ABSTRACT:
A conveyor lubrication apparatus includes a counter for energizing lubrication devices once for each predetermined number of cycles of the conveyor past a lubrication station. Timers energized by the counter activate control valves for a predetermined period of time to supply lubricant to parts of the conveyor as each part reaches the lubrication station. A current sense circuit detects current flow to the control valves and energizes the central lubricant supply pump to pressurize the lubricant flow lines for a predetermined period of time, at the end of which the pump is de-energized until the next control valve is energized. A pressure sensor is disposed in the lubricant flow lines to detect a low pressure level and causes the pump to be de-energized and an alarm to be activated.
