Apparatus for filling paint cartridges

A paint filling apparatus that fills a paint cartridge with a paint of a color selected from a plurality of color paints, comprising:

• a plurality of header portions;
• and
• one common manifold portion that is able to supply a cleaning liquid to each of the header portions, wherein:
• one side of each of the header portions is attachable to and detachable from the paint cartridge, and another side of each header portion is attachable to and detachable from the common manifold portion;
• each header portion is provided with a paint supply channel without involving the common manifold portion for filling the paint into the paint cartridge;
• one end portion of the paint supply channel of each header portion is linkable in communication with an inside of the paint cartridge, and another end portion of each paint supply channel is linked in communication with a corresponding one of a plurality of paint supply sources that are provided separately for each of the colors of the paints;
• and
• an intermediate portion of each paint supply channel is provided with a paint valve that controls an open-closed state of an upstream side of the paint supply channel, wherein
• a site of linkage in communication of the paint supply channel of each header portion with respect to the inside of the paint cartridge is provided with an open-close valve that controls the open-closed state of a downstream side of the paint supply channel,
• a site of attachment and detachment of the common manifold portion with respect to each header portion is provided with a trigger valve,
• the trigger valve becomes engaged with the open-close valve of a selected one of the header portions as the selected header portion and the common manifold portion are linked, and
• the open-close valve performs opening and closing actions in coordination with actions of the trigger valve.
