Process and apparatus for dispensing liquid colorants into a paint can, and quality control therefor
Patent number: 5268849Abstract: An automated paint-batching system for producing paint cans of any size and color. The system includes a plurality of paint-batching cells, with each cell having a machine comprised of either one or two dispensing stations. When two dispensing stations are used, the two dispensing stations are: A first tint-station, where a small volumetric dispensing of the base, water-base or oil-base, of the paint is dispensed, in order to wet the bottom of the can, at which first station, thereafter, is dispensed all of the liquid colorants making up the formula of the paint can, at which the remainder of the base of the formula of the paint is dispensed, and a second base-dispensing station. Each of the first and second stations of the paint-batching machine of the invention has operatively associated therewith a weighing platform upon which rests the paint can during the dispensing at the respective station used in quality-control weighing of each dispensing.Type: GrantFiled: November 14, 1991Date of Patent: December 7, 1993Assignees: Dunn-Edwards Corporation, Fluid Management Limited PartnershipInventors: Philip Howlett, Larry Frederickson, Kenneth N. Edwards, Edward D. Edwards -
Patent number: 5268620Abstract: A control system for mixing materials in a container. A screw-driven pressure plate clamps the container during mixing.

Patent number: 5137367Abstract: An automated apparatus for mixing ingredients stored in closed containers includes two or more mixing mechanisms. A diverter gate upstream of the mixing mechanisms guides containers to one or the other mechanism, as desired. Powered conveyors move the containers past the diverter gate and retractable pusher arm assemblies load the containers onto the mixing mechanisms. After a mixing operation is completed, the pusher arm assemblies discharge the containers onto an exit conveyor for transport to a remote packaging station. Sensors are disposed along the path of travel of the pusher arm assemblies to control operation thereof, providing a ready indication that a container is properly positioned on a mixing mechanism, and that the mixing operation can be initiated.Type: GrantFiled: September 28, 1990Date of Patent: August 11, 1992Assignee: Fluid Management Limited PartnershipInventors: Kenneth J. Madonia, Niles M. Dwyer

Patent number: 5119973Abstract: Dispenser actuating apparatus includes guide rails carrying a valve actuator at one end. A pump actuator is mounted for sliding along the guide rails, and the guide rails are mounted for sliding along their central axes. Separate motors and drive belts reciprocate the valve and pump actuators with independent movements.Type: GrantFiled: December 14, 1990Date of Patent: June 9, 1992Assignee: Fluid Management Limited PartnershipInventors: William Miller, Leen Hellenberg

Patent number: 5116134Abstract: An automated apparatus for mixing ingredients stored in closed containers includes a gyroscopically mounted frame with a clamping arrangement for clamping a container therein. A shuttle moves back and forth between a conveyor and the frame carrying containers to and from the frame. An injection arm carried on the shuttle moves the container into the frame, and an ejection arm moves the container from the frame to the shuttle, for return to the conveyor. A braking alignment mechanism orients the frame to receive a container.Type: GrantFiled: September 28, 1990Date of Patent: May 26, 1992Assignee: Fluid Management Limited PartnershipInventors: Kenneth N.

Patent number: 4953985Abstract: An apparatus for mixing liquid paint colorant in a plurality of containers. Flexible cables are rotated about their length by a drive motor to rotate agitators in each container. The cable ends which drive the agitators are aligned with the rotational axes of the agitators. Each container has an open upper end which is closed by a cover having an attached mechanism for imparting rotation from the cables to the agitators. The agitators are disabled by disengaging one end of the cable from the drive motor, disengaging the other end of the cable from the mechanism on the container cover, or removing the cover with the cable intact to separate the mechanism from the agitator. The cables are bowed in an inverted U-shape between the drive motor and container covers. A lid extends over the bowed cables and has a rim that bears against the container covers to maintain them in closed position on the container during operation.Type: GrantFiled: July 17, 1989Date of Patent: September 4, 1990Assignee: Fluid Management Limited PartnershipInventor: William A. Miller
