Abstract
Methods and apparatus for automatically cleaning a roll for handling sheet stock while in service, including single ended reciprocally actuated scrubbing of a fully roll surface width polishing surface swingingly engaged with the roll surface to provide effective cleaning action without leaving residual scars on the roll surface. Single ended actuation of the scrubbing action is enhanced with special self aligning bearings.
Claims16
An apparatus for automatically cleaning contaminants from a circulating surface having a surface width perpendicular to its direction of motion, comprising:
- means for orienting at least one polishing block having a face parallel to said circulating surface along said surface width;
- means for swingingly engaging said at least one polishing block with said circulating surface about a supporting axis of rotation;
- and
- means for reciprocally scrubbing said circulating surface with each said polishing block along said entire circulating surface width.
An apparatus for automatically cleaning contaminents from the surface of a rotating cylindrical roll, said roll having a surface width perpendicular to its direction of rotation and a roll axis of rotation, comprising:
- a plurality of polishing blocks extending in a serial tandem relationship over a width greater than said roll surface width;
- a plurality of polishing block mounting arms, each said arm fastened to a different one of said polishing blocks, said arms arranged substantially perpendicular to said roll surface width and substantially parallel to said roll surface;
- a rotatable linear mounting support having a supporting axis of rotation parallel to said roll axis and an axial freedom of movement along said supporting axis, said mounting support resiliently supporting the ends of said block mounting arms opposite said polishing blocks;
- a linear actuator for linearly reciprocating said mounting support along said supporting axis;
- and
- at least one counterweighted lever, attached to said mounting support, for rotating said polishing blocks against said roll surface.
