Automatic grease dispensing monitoring and alarm system

Abstract

An automatic grease dispensing monitoring and alarm system using a control unit in each automatic grease dispenser to provide message to a center monitoring control and alarm system wirelessly, achieving wireless remote lubrication control, abnormality alarm, and auto grease-dispensing functions. Each automatic grease dispenser comprises a driving mechanism for driving a piston to dispense the lubricating grease, a microprocessor-based control unit for the setting of the lubricating cycle and for checking the grease dispensing amount subject to the detection of the rate of turn of the driving mechanism through a sensor and a black and white reflective plate.

1 . An automatic grease dispensing monitoring and alarm system comprising:
 a plurality of automatic grease dispensers installed in mechanical parts at different locations in a factory, said automatic grease dispensers each comprising a housing covered with a top cap, a grease container mounted inside said housing and connected to the associating mechanical part and holding a lubricating grease, a piston mounted in said grease container and adapted to force the lubricating grease out of said grease container into the associating mechanical part, a propelling device controllable to move said piston, a driving mechanism adapted to drive said propelling device to move said piston, said driving mechanism comprising a motor and a speed reducing gear set coupled between said motor and said propelling device, a control unit adapted to control operation of said driving mechanism, said control unit comprising a microprocessor, a sensor and a black-and-white reflection signal plate adapted to detect the rate of turn of said driving mechanism and to feed back detected data to said microprocessor for reading, an indicator lamp adapted to give a visual warning signal when the reading of said microprocessor is out of a normal range, a battery mounted in said top cap and electrically connected to said control unit and said driving mechanism to provide the necessary working voltage, and a transmitter electrically connected to said microprocessor for data transmission wirelessly to a center monitoring control and alarm system; and   a center monitoring control and alarm system disposed in communication with the transmitters of said automatic grease dispensers wirelessly and adapted to calculate and record the amount of the lubricating grease dispensed by each of said automatic grease dispensers, to set and calculate the lubricating cycle of each of said automatic grease dispenser, to record the routine check and maintenance records of each of said automatic grease dispensers, and to provide data inquiry and message updating functions, said center monitoring control and alarm system giving an alarm signal upon interruption of the connection of one of said automatic grease dispensers and indicate the location and data of the automatic grease dispenser that is in trouble.
