Definitions

  • This specification relates to dispensing toner.
  • a toner is a pure color of paint including several elements including a pigment, a solvent, and a resin.
  • Liquid toners include paints, inks, colorants and other fluids used to dye or color a base material. Toners are often mixed together in order to produce a particular result.
  • automotive paints are typically created using a precise mixture of toners.
  • the mixture for a particular color is defined by a recipe.
  • the recipe identifies the toners, as well as the amounts of each toner. Failure to mix the correct amount of toner results, for example, in a paint that does not exactly match the desired color.
  • Conventional paint mixing is a manual process.
  • a human user reviews the recipe and then manually pours each toner into a container, e.g., on a scale, until the specified amount of each toner has been poured.
  • human pouring often leads to inaccurate pours, especially when a precise amount of each toner is required to form a specific toner mix.
  • Motorized toner dispensing apparatuses typically use one or more motors to control a spout for a container of toner.
  • conventional motorized toner dispensers do not adjust quickly and often over or under pour the toner.
  • Conventional motorized toner dispensing apparatuses use a type of pump activated, for example, by a motor, air driven or electric, which due to the nature of the pump, requires occasional calibration.
  • toners contain pigments that can be abrasive
  • the pumps are subject to wear, leading to the need to calibrate the pump.
  • conventional spouts are poorly sealed leading to dripping and introduction of contaminants into toner containers as well as curing of toner within the containers.
  • conventional spouts require periodic cleaning, especially when changing empty toner containers.
  • a toner dispensing system that includes a toner container; a cap and valve assembly coupled to the toner container, the cap and value assembly including a movable valve assembly, the movable valve assembly having a first position and a second position, a toner path, and an air inlet path, where in a first valve assembly position the toner path and the air inlet path are closed, and in a second valve assembly position the toner path and the air inlet path are open; an air assembly including a first air supply coupled to the air path of the cap and valve assembly and a second regulated air supply coupled to the toner container; and a control assembly for controlling the second air supply.
  • the toner dispensing system further includes a scale for measuring dispensed toners from the cap and valve assembly; and a flow control system that regulates the second air supply to control the flow of toner through the toner path based on the scale measurement.
  • Controlling the flow of toner further includes adjusting the second regulated air supply to the toner container, and where the air pressure of the toner container determines the flow rate of toner through the toner path.
  • the cap and valve assembly further includes an elongated outer tube and an elongated inner tube, the elongated inner tube being movable relative to the outer tube, the elongated outer tube including openings for the air intake path and the toner path, the inner tube including the air intake path and the toner path, where the movable valve assembly moves the inner tube relative to the outer tube such that the air inlet path and toner path are aligned with respective openings in the outer tube.
  • the cap and valve assembly further includes an anti-drip cap where the anti-drip cap is movable relative to an outlet of the toner path such that in a first position the outlet is open allowing toner to pass through the outlet from the toner path and in a second position the outlet is closed sealing the toner path preventing substantially all toner from passing through the outlet.
  • the air inlet path selectively allows air to be injected into the toner container.
  • the control assembly further controls the first air supply to selectively position the movable valve assembly in an open and a closed position.
  • the first air supply and the second air supply have a common source or a separate source.
  • one aspect of the subject matter described in this specification can be embodied in methods that include the actions of identifying an amount of toner to dispense; initializing a scale to measure the amount of dispensed toner; activating a first air supply, the first air supply configured to provide air to a toner container when a valve is moved to a dispensing position; activating a second air supply, the second air supply moving the valve to the dispensing position such that toner is dispensed at a specified flow rate; monitoring the scale to determine when a first threshold amount of toner has been dispensed; when the threshold amount of toner has been dispensed, reducing the flow rate of the toner to a reduced flow rate; monitoring the scale to determine when a second threshold amount of toner has been dispensed; and deactivating the first air supply when the second threshold amount of toner has been dispensed, the deactivating of the first air supply stopping the flow of toner.
  • Other embodiments of this aspect include corresponding systems, apparatus, and computer program products

  • the method further includes receiving a user selection of a recipe, the recipe identifying toners and corresponding amounts to be dispensed and dispensing a first toner in the recipe and then a second toner from the recipe. Reducing the flow rate includes reducing a pressure in the toner container provided by the first air supply.

  • the cap and valve assembly further includes a toner inlet tube coupled to the toner path for directing toner from a bottom portion of the toner container into the toner path.
  • a toner inlet tube coupled to the toner path for directing toner from a bottom portion of the toner container into the toner path.
  • the valve cap also incorporates a moving wiping anti-drip cap to prevent drips after dispensing and to seal the end of the toner delivery device from air and containments and reduce curing of toner.
