Embodiment Construction

[0030] figure 1 is an isometric view of an example toner dispenser 100 . Toner dispenser 100 includes first and second toner containers 102 , first and second cap and valve assemblies 104 , scale 106 , optional scale control interface 108 , and housing 110 .

[0031] Each toner container 102 holds a volume of a corresponding toner (eg, a corresponding paint color). The toner container 102 may have different sizes depending on the application (eg, half liter, one liter, or two liter container volume). Larger sized containers can be stored remotely and the contents of the larger container can be dispensed using the cap and valve assembly 104 through the use of adapters and tubing.

[0032]Each of the toner containers 102 is coupled to a corresponding cap and valve assembly 104 using a cap 114 . Each cap and valve assembly 104 couples a respective toner container 102 to a horseshoe coupling 112 to allow dispensing of a particular toner. In some implementations, each valve ass...

Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for dispensing toners. In one aspect, a toner dispensing system 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.

Description

Background technique [0001] This instruction is concerned with dispensing toner. [0002] Toners are solid-color paints that contain several elements, including pigments, solvents, and resins. Liquid toners include paints, inks, colorants and other fluids used to tint or tint a substrate. Toners are often blended together to provide specific results. For example, precise mixtures of toners are often used to create car paint. Recipes are used to define mixtures for specific colors. The recipe specifies the various toners and the amount of each. Failure to mix the correct amount of toner results in, for example, paint that does not exactly match the desired color. [0003] Conventional paint mixing is a manual method. The user reviews the recipe and then manually pours the various toners into containers, such as on a scale, until the specified amount of each toner has been poured. However, human pouring often results in inaccurate pouring, especially when precise amounts ...
