PEELING APPARATUS WITH LONG-LIFE FINGER-FRAME CAM ROLLERS

摘要

Peeling apparatus and cam followers for lowering and raising the finger frames of roller-type peeling apparatus. The cam followers have monolithic hardened stainless steel cam rollers with journals extending outward of central wheels into bronze bushings retained stationarily in holders. The monolithic cam rollers roll on pivoting cams at the four corners of the finger frame to raise and lower the finger frame in synchrony with the back and forth rotation of peeling rollers forming peeling channels. Support rollers supporting the ends of the peeling rollers also rotate in stationary bronze bushings.

主权项

1. Peeling apparatus comprising:
a peeler frame; a plurality of peeling rollers mounted in the peeler frame and extending in parallel to form peeling channels between adjacent peeling rollers; a finger frame having a plurality of pressure fingers extending into the peeling channels; a plurality of cams attached to the peeler frame; a drive system for rotating the peeling rollers back and forth and rocking the cams back and forth in synchrony with the rotation of the peeling rollers; a plurality of cam followers attached to the finger frame, each of the cam followers having a cam roller that rides on one of the cams to lower and raise the finger frame and the pressure fingers in synchrony with the rotation of the peeler rollers; wherein each of the cam followers further includes:
a holder having first and second holes aligned and spaced apart across a gap at a first end of the holder;a first bushing received stationarily in the first hole, and a second bushing received stationarily in the second hole;a cam roller including a central wheel, a first journal extending outward from a first side of the wheel and through the first bushing, and a second journal extending outward from an opposite second side of the wheel and through the second bushing, wherein the first and second bushings form bearing sleeves for the first and second journals as they rotate when the cam roller rolls on one of the cams; andwherein the first and second bushings are made bronze and the first and second journals are made of a second material harder than bronze.
