Central lubrication system for conveyor trolleys - has track section mounting limit switches which control firing of solenoid valves

摘要

The system includes a wheel positioning locator in the form of a trolley track section having openings through the web and movement controlling cam blocks. The controllers engage and orient trolley wheels and chain assuring proper positional location of the bearings adjacent the emission point of lubricant capillaries and avoidance of damaging contact between capillaries and moving trolleys or chain equipment. One track flange provides support for electrical equipment and limit switch. The other track flange supports the trolley wheels. The lubricating circuit is a constant pressure circulating system from a central storage tank and running to valves and the valves located at the capillary tubes. The valves and the valves located at the capillary tubes. The valves are solenoid operated and the solenoids are fired by capacitor discharge, the interval of solenoid performance being adjustable electrically to vary the quantum of delivered lubricant includes the adjustment of lubricating interval on the delivery of a metered amount of liquid lubricant through the capillaries and to the lubrication situs with zero or minimal drip. Plural lubricator stations or lubrication heads are served from a common or central lubrication source remote from the situs of lubrication application.
