Abstract: An idler roller is disclosed which includes a non-rotating shaft, a roller shell positioned around the non-rotating shaft and a bearing assembly proximate each end of the roller shell. The bearing assembly includes an outer labyrinth member and an inner labyrinth member having an integrally formed shaft seal, wherein the inner and outer labyrinth members define a labyrinth seal and the integrally formed shaft seal sealingly engages an outer surface of the non-rotating shaft.

Abstract: A conveying apparatus comprises an elongated conveying bed which includes a proximal end and a distal end. A support structure for the conveying bed accommodates vibratory motion of a portion of the conveying bed extending from the proximal end a substantial distance toward the distal end but dampens vibratory motion at the distal end. In addition, a piezoelectric driver is operatively connected to the conveying bed adjacent the proximal end. Consequently, operation of the piezoelectric driver will induce a wave motion in the conveying bed which will effectively convey a material from the proximal end to the distal end.

Abstract: The present invention relates to a method and apparatus for dimensionally sorting a group of received articles, like fruits and vegetables, and using the determined different sizes for differentiation during the subsequent processing and handling of the articles. Generally, the size and shape of each article is determined by the degree of deflection of one or more sensor heads located along a path the article is traversing. The determined size and shape is then used to direct the article during the subsequent processing and/or handling of the article.
