Abstract
Buffing of a footwear component allows for an alteration of the component surface to achieve an intended surface for aesthetics and/or manufacturing purposes. The buffing is performed in a system having a vision module, a sidewall buffing module, an up surface buffing module, and a down surface buffing module. Each of the buffing modules are adapted for the unique shape and sizes of a footwear component to effectively and automatically buff the footwear component.
Claims18
An article of footwear buffing system, the system comprising:
- a sidewall buffing module comprising:
- (1) a first brush, the first brush having a cylindrical form with a plurality of bristles extending outwardly from a rotational axis of the first brush, the rotational axis extends along a longitudinal direction of the cylindrical form;
- (2) a first brush rotational drive, the first brush rotational drive functionally connected with the first brush to rotate the first brush about the first brush rotational axis, and
- (3) a first footwear component holder, the first footwear component holder positioned to secure a footwear component for contact with the first brush;
- an up surface buffing module comprising:
- (1) a second brush, the second brush having a cylindrical form with a plurality of bristles extending outwardly from a rotational axis of the second brush, the rotational axis extends along a longitudinal direction of the cylindrical form;
- (2) a second brush rotational drive, the second brush rotational drive functionally connected with the second brush to rotate the second brush about the second brush rotational axis, and
- (3) a second footwear component holder, the second footwear component holder comprised of a first support and a first clamp, the first clamp is positioned to contact an up surface of the footwear component and the first support positioned to contact a down surface of the footwear component;
- and
- a down surface buffing module comprising:
- (1) a third brush, the third brush having a cylindrical form with a plurality of bristles extending outwardly from a rotational axis of the third brush, the rotational axis extends along a longitudinal direction of the cylindrical form,
- (2) a third brush rotational drive, the third brush rotational drive functionally connected with the third brush to rotate the third brush about the third brush rotational axis,
- (3) a third footwear component holder comprised of a plurality of rollers forming a support plane, wherein each of the rollers has a rotational axis parallel with the third brush rotational axis and the third brush rotational axis is positioned on a first side of the support plane and at least a portion of the third brush plurality of bristles extending to a third side of the support plane, and
- (4) a compression member, the compression member is positioned on the third side of the support plane.
