Sorter with noise reduction

Reducing the operating impact noise of a moving bins sorter of the type in which the bins of the sorter are sequentially incremented with a rotatable open mouthed "C" cam drive, where the open ends of the "C" cam on opposite sides of the open mouth provide operative bin engaging cam surfaces for engaging a cam engaging portion of the bins, without adversely affecting the contacting surfaces wear rate, by providing cantilevered arms of limited flexibility supporting the bin engaging end portions of the "C" cam to provide limited flexing of at least one of the bin engaging end portions of the "C" cam when at least one of these bin engaging end portions operatively engages a bin, for impact noise reduction. The "C" cam may further include an internal chordal cross brace. The "C" cam may further include undercut or relieved areas to make the cantilevered arms thinner adjacent the bin engaging end portions, and/or a highly resilient donut shaped member mounted internally of the open mouth of the "C" cam and positioned to partially engage the cam engaging portion of the bin entering the open mouth of the "C" cam.
