ABSTRACT:
A conveyor lubricator for lubricating moving parts in a conveyor mechanism comprises an air operated oil injector that dispenses a measured quantity of oil on each part to be lubricated when such part reaches a predetermined position on the track; an air assist mechanism that generates an air flow across the oil outlet so as to urge the oil toward said predetermined position; and a cam operated actuator valve that provides air pressure to actuate the oil injector and air assist whenever a moving part reaches said predetermined position. A timed pulse valve connected to the actuator valve automatically deactivates the air flow after a predetermined period of time, even if the actuator valve still remains actuated by continued engagement with the conveyor. More than one cam operated actuator valve can be employed in the system in order to provide lubrication for an increased number of moving parts of the conveyor mechanism with a single set of oil injectors. The cam operated actuator valve includes an adjustment mechanism that permits placement of the valve in different positions. The lubricator also can include a selective actuation mechanism in order to actuate and deactuate the system whenever desired. An air counter can be employed to automatically actuate and deactuate the system at regular intervals.
