When fitting a brush to a machine, one check should never depend on memory: matching the brush to the head’s direction of rotation. For Cepicat Quickfix brushes, the colour code is simple: blue for clockwise rotation (CW), red for counterclockwise rotation (CCW).
Visual mistake-proofing when changing brushes
Poka-yoke means preventing mistakes or making them apparent before they reach the next operation. Applied to brush fitting, colour identification helps the operator recognise which brush belongs on each head.
The operator has a visible reference on the component itself, rather than relying entirely on remembering each brush’s position. Colour is an identification aid; it does not physically prevent incorrect installation.
Two colours, two directions
The illustration shows two 150 mm Quickfix brushes: red on the left with a counterclockwise arrow, blue on the right with a clockwise arrow and mounting geometry that mirrors the red brush. Both have the same diameter. The CCW and CW labels reinforce the message so identification does not rely on colour alone.
Left and right refer to positions in this illustration, not mandatory positions on the machine. Each brush must match its head’s direction of rotation.
Compare arrows from the same viewpoint
The same rotation appears clockwise from one side of a disc and counterclockwise from the other. Always use the viewing direction specified by the machine manufacturer and its markings when matching brush and machine.
With the machine stopped and following its brush-change procedure, check the head’s rotation marking, the brush colour and identification, and secure attachment before restarting.
That is the purpose of this visual poka-yoke: to make the correct choice easier during fitting and reveal a mix-up before the machine starts.
