A diagnostic apparatus for a powder coating material pump. The diagnostic apparatus includes a detector that uses pressure or flow to detect a fault in the pump, the diagnostic apparatus being external the pump, internal the pump or a combination of external and internal the pump. Another diagnostic device is provided for a powder coating material pump, and includes a light source in close proximity to the pump, the light source having an on condition and an off condition wherein one or both of the on condition and off condition provides information about the pump performance. An exemplary pump is a dense phase powder coating material pump.

Dense phase pump diagnostics

Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to makes selections of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation.

A diagnostic apparatus for a powder coating material pump includes a detector that uses pressure or flow to detect a fault in the pump, the diagnostic apparatus being external the pump, internal the pump or a combination of external and internal the pump. Another diagnostic device is provided for a powder coating material pump, and includes a light source in close proximity to the pump, the light source having an on condition and an off condition wherein one or both of the on condition and off condition provides information about the pump performance. An exemplary pump is a dense phase powder coating material pump.

Control method and apparatus for a manual spray gun may include a second manually actuated trigger disposed on the spray gun handle, with the second trigger being operational to select one or more coating operation parameters.

Coating material spray gun

Apparatus for detecting powder flow along a powder flow path includes a light source and a light detector for detecting light from the light source directed across the powder flow path as powder flows through said powder flow path. A circuit receives the output from the light detector and determines an average or RMS of the signal received by the light detector. The circuit may determine whether there is flow or no flow of powder or whether there is a change in flow rate of powder. Preferably, the apparatus is used in combination with a dense phase powder pump, which causes the powder to flow in pulses from the pump outlet into the powder flow path. More preferably, the light source and detector are enclosed in a housing that is connected between the pump outlet and a powder feed hose which supplies powder to a spray gun or hopper.

A pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided. A pump control feature is provided for air flow rate control during positive and negative pressure conditions.

Pump with suction and pressure control for dry particulate material

Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to make selections or changes of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections or changes without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation. The display may include numeric information, for example, data relating to a coating function being displayed.

A central controller for a powder coating system has a single processor connected to a memory, a gun controller input/output device and gun control logic for controlling a characteristic of a spray gun. An air flow controller input/output device and air flow control logic for controlling a characteristic of a pump providing air flow may also be included. A process input/output device for electrically communicating with a process input or a process output may also be included. Part identification and tracking logic, gun triggering logic, gun movement logic, booth control logic, part profiling logic and system monitoring and logging logic may also be included.
