Paint dispensing apparatus
View Patent ↗A paint dispensing apparatus having a housing with a turntable rotatably mounted to the housing about a vertical axis. A plurality of stations on the turntable are circumferentially spaced from each other and each station is adapted to receive a paint dispenser having a plunger in which movement of the plunger dispenses paint from the paint dispenser. An indexing drive, upon activation, rotates the turntable to sequentially position the stations at a dispensing position. When at the dispensing position, an actuator mounted to the housing mechanically engages the plunger of the paint dispenser positioned at the dispensing station. A receptacle is mounted to the housing beneath the turntable and aligned with the dispensing position. A controller is then coupled to the indexing drive and is programmed to sequentially move the stations into alignment with the dispensing station and, when at the dispensing station, move the actuator to dispense paint from the paint dispenser at the dispensing position into the receptacle.
1. A paint dispensing apparatus comprising:
a housing,
a turntable rotatably mounted to said housing about a vertical axis,
a plurality of stations on said turntable, said stations being circumferentially spaced from each other,
each station adapted to receive a paint dispenser having a plunger wherein movement of said plunger dispenses paint from the paint dispenser,
an indexing drive which, upon activation, rotates said turntable to sequentially position said stations at a dispensing position,
an actuator mounted to said housing which mechanically engages the plunger of the paint dispenser positioned at said dispensing station,
a receptacle supported by said housing beneath the turntable and aligned with said dispensing position,
a controller coupled to said indexing drive and said actuator, said controller being programmed to sequentially move said stations into alignment with said dispensing position and, when at said dispensing position, move said actuator to dispense paint from the paint dispenser at said dispensing position into said receptacle,
wherein said indexing drive comprises a track on the bottom of said turntable, said track comprising a plurality of circumferentially adjacent V-shaped segments, and a piston and cylinder, said piston having a free end slidably mounted in said track.
2. The apparatus as defined in claim 1 wherein each paint dispenser comprises a container having an open top and a lid secured to said open top of said container, said plunger being mounted on said lid.
3. The apparatus as defined in claim 1 wherein each station includes at least one slide rail which cooperates with a slide on the paint dispenser to slidably receive and position the paint dispenser into said station.
4. The apparatus as defined in claim 1 and comprising a scale positioned under said receptacle, said scale having an output signal connected as an input to said controller.
5. The apparatus as defined in claim 1 and comprising a bumper attached to said housing which engages and urges the paint dispenser radially inwardly when at the dispensing position.
6. The apparatus as defined in claim 5 wherein said bumper is aligned with said dispensing station.
7. The apparatus as defined in claim 1 wherein said controller comprises a processor having access to paint formulae for a plurality of different colors of paint.
8. The apparatus as defined in claim 1 wherein each paint dispenser is radially slidably received in its associated station.
9. The apparatus as defined in claim 1 wherein said piston reciprocates in a radial direction relative to the axis of said turntable.
