ABSTRACT:
A load-entry assembly for a conveyor system includes a conveyor section having laterally spaced side frame members supporting a plurality of load-carrying rollers for rotation about transverse axes which are arranged in a common plane above the side frame members to transport a load in a longitudinal direction between a first end and a second end of the conveyor section. A pair of first elongated tracks is mounted longitudinally to opposed sides of the conveyor section, and each track includes a lower horizontal track section, an upper horizontal track section, and an inclined track section connecting the lower and upper horizontal track sections in angular relationship thereto. A pair of second elongated tracks is also mounted longitudinally to opposed sides of the conveyor section. A trolley is both vertically and horizontally movable along the track sections of the first tracks in a generally constant parallel relationship to the plane of the load-carrying roller between a first position below the plane of the load-carrying rollers to allow movement of the load over the trolley to a second position above the plane of the load-carrying rollers to engage and push the load. Guide members are coupled to the trolley and movable horizontally along the second tracks in response to a propelling unit. The coupling between the guide members and the trolley controllably allows the entire trolley to move vertically relative to the guide members between two different planes to maintain its constant relationship to the plane of the load-carrying rollers.
