Abstract
A random orbital finishing apparatus for finishing the surfaces of solid material including wood, plastic, metal and composites, but most particularly plastic solid surface materials. The apparatus includes a conveyor for transporting such unfinished material pass a uniquely mounted random orbital sander where it is subsequently finished thereby. The random orbitals may be dually mounted and in an offset position. The apparatus may further include a system of proximity sensors and air cylinders which enable the random orbitals to automatically adjust their position onto the surface to be finished when the material is passed thereby and subsequently return back to a starting position after the material passes.
Claims16
An apparatus for finishing surfaces of solid materials, comprising:
- a frame having a front end and a back end;
- a conveyor system extending generally from said front end to said back end;
- a drive means supported by said frame, said drive means connected to a drive shaft to provide a first axis of rotation;
- at least two orbital shafts coupled to said drive shaft whereby each orbital shaft provides a second axis of rotation;
- at least two discs, each of said at least two discs having a center providing a third axis of rotation, each of said at least two discs having a material engaging surface;
- each of said at least two orbital shafts being coupled to each of said at least two discs in an offset position form said center such that each of said at least two discs is rotatable about said third axis while said third axis rotates about said second axis;
- a cam and counterweight assembly to provide the coupling between the orbital shafts and the discs;
- and
- wherein said material engaging surface is capable of being detachably covered by a finishing abrasive whereby when each of said at least two discs is rotating and each of said at least two discs contacts a surface of said solid materials, said finishing abrasive finishes the surface of said solid materials.
A surface finishing apparatus, comprising;
- a frame having a front end and a back end;
- a housing;
- a mount connecting said housing to said frame;
- a drive shaft within said housing, said drive shaft powered by a drive means;
- said drive shaft coupled to at least two orbital shafts, at least a portion of said at least two orbital shafts extending outside of said housing;
- at least two discs, each of said at least two discs having a center and a material engaging surface, each of said at least two discs coupled to each of said at least two orbital shafts, at a position near said center to provide a first disc rotation about the orbital shaft and a second disc rotation about said center;
- and
- a cam and counterweight assembly to provide the coupling between the orbital shafts and the discs.
