Problems solved by technology

When different colors of paint are required, several different applicators have traditionally had to be used, one for a different color, because changing colors using the same applicator and tubing requires time-consuming cleaning operations
The use of multiple different coating units and conduits during robotic operations adds significantly to the complexity and cost of coating equipment

Embodiment Construction

[0021] refer to figure 1 , which shows a powder coating plant with a coating chamber 10, inside the coating chamber 10 is a robot-operated powder spray coating device 12 for applying paint to a component 14, which may be, for example, a vehicle body part. Powder is supplied from the powder unit 16 to the coating device 12 by means of a suction unit 18 through a conduit (not shown). The powder unit 16 and the suction unit 18 are suitable as a color changing system, which will be referred to below figure 2 to Figure 4 for a more detailed description. like figure 1 As shown, a controller 20 controls the operation of the powder coating apparatus.

[0022] figure 2 A powder unit 16 and a suction unit 18 forming an embodiment of the color change system are shown. Frame 22 supports a plurality of powder containers 24 in the form of a row of fluid tanks filled with powder, each container 24 holding a powder of a different color ( figure 2 Five such containers are shown in , ...

Abstract

A colour change system for a powder coating facility comprises a plurality of containers 24a-24e each with a different colour powders; a conduit for conveying powder from one of the containers 24a-24eto a coating applicator 12; a suction unit 18 connected to the conduit and having an end-piece with a powder-drawing inlet opening; a cleaning unit 34; a translation mechanism for moving the end-piece; and a controller. The containers 24a-24e and the cleaning unit 34 each have an opening 25 for receiving the end piece. The controller effects a change of powder colour by controlling the translation mechanism to extract the end-piece from a first container 24d, to move it to the cleaning unit 34, and after cleaning to move the end piece to a second container 24e. The system allows automated cleaning between colour changes, which reduces operating downtime.

Description

technical field [0001] The invention relates to a color change system for powder coatings. More specifically, the present invention relates to a system for automatically changing the color of powder coatings, suitable for use with manually or robotically operated coating devices. Background technique [0002] Powder coatings are widely used in numerous industries such as vehicle manufacturing to coat components, usually metal components. The colored powder is supplied from a powder reservoir to a coating device, such as a spray gun, through a suitable conduit. Powder coating is increasingly carried out in automated production plants, for example using robot-controlled coating units. When different colors of paint are required, several different applicators have traditionally had to be used, one for a different color, because changing colors using the same applicator and tubing requires time-consuming cleaning operations . The use of multiple different coating devices and...
