Paint Mixer Patents (Class 366/605)
  • Patent number: 5507574
    Abstract: Apparatus for mixing liquids such as ink and paint includes a support platform having a plurality of rotating spindle and support tray combinations. Each tray is adapted to receive and support a respective open container or bucket containing ink or paint to be mixed, while each spindle is coupled to and rotationally driven by a respective hydraulic motor. A blade positioned within each container thoroughly mixes the container's contents as the container rotates. Hydraulic motor control allows each container to be rotated at a selected fixed RPM or at a continuously variable RPM for improved control of mixing of the materials within the container. By controlling mixer RPM, increased quantities of the ingredients may be mixed within the tub without spilling the contents, while also permitting faster, more thorough mixing of the ingredients. Each support tray is adapted to receive either a large container such as on the order of 15 gallons or a 3.5 gallon kit adaptor to mix smaller portions.

  • Patent number: 5437505
    Abstract: In a paint mixing apparatus, a paint can carrying bail retaining device, said device comprising a retaining ring that is movably attached to a blending bucket, said bucket having a diameter selected such that a paint can easily be inserted therein for the mixing or blending operation. The retaining ring has a radius slightly larger than the radius of the mixing bucket plus the thickness of the paint can carrying bail. The retaining ring has a loading/unloading and a retaining position. When the ring is displaced from its retaining position, which is corresponds to its normal position, into its loading/unloading position, sufficient clearance is created to allow the bail to swing freely into a mixing position, where it rests along the outside of the mixing bucket. When the ring is returned to its retaining position, the bail is secured in the mixing position as a result of a lack of sufficient clearance to allow the bail to swing away from its position along the outside of the mixing bucket.

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.

  • Patent number: 5116134
    Abstract: 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.

  • Patent number: 5083591
    Abstract: 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 the first station, thereafter, is dispensed all of the liquid colorants making up the formula of the paint can, and a second base-dispensing station at which the remainder of the base of the formula of the paint is dispensed. 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.
