Shoe Sole Portion Painting System

摘要

Automated painting of a shoe sole portion is enhanced by use of a mask cover and an air knife with a paint assembly. The mask cover is positioned in front of a paint-emitting portion of a spray nozzle and is adapted to obstruct at least a portion of the paint intended to be emitted by the spray nozzle. The air knife is coupled to the mask cover and is adapted to emit a laminar fluid flow over the mask cover. The laminar fluid flow helps to limit unwanted diffusion of the paint as it passes along its intended spray path.

主权项

1. A shoe sole portion painting system comprising:
a paint assembly comprising at least a spray nozzle adapted to emit a liquid material from a front region of the spray nozzle; and a masking assembly comprising:
a mask cover coupled to the spray nozzle, the mask cover positioned at a predefined distance in front of the front region of the spray nozzle such that it partially obstructs the paint emitted by the spray nozzle, the mask cover having a top region and a bottom region; andan air knife coupled to the top region of the mask cover and adapted to project a laminar fluid flow in a generally angled direction towards the bottom region of the mask cover.
