Abstract:
A transverse conveyance apparatus for roller conveyors comprising a frame, a crosswise feeding mechanism mounted to the frame and a lift device for raising and lowering the frame,wherein the crosswise feeding mechanism has rotating portions, each of which is of a width freely movable through between two adjacent rollers of the conveyor, so that articles are transported in a direction crossing that in which the articles are to advance on and along the roller conveyor, wherein the lift device comprises a cylinder, lids closing opposite ends of the cylinder, fixed shafts protruding outwards and longitudinally of the cylinder that is coaxial with said shafts capable of rotating relative to the lids, a motor that is built in the cylinder and drives it to rotate around and relative to the fixed shafts, a reducer built in the cylinder so as to reduce the motor's rotational speed transmitted thereto, and a resistance unit also built in the cylinder and increasing resistance against rotation of said cylinder, wherein attachment-engaging portions are formed on the respective lids and disposed longitudinally of the cylinder to face outwards so that the attachment-engaging portions and the cylinder do rotate together in unison with each other, the attachment-engaging portions having axes arranged offset with respect to axes of the fixed shafts, and wherein the fixed shafts are held in position in and by one member selected from the group consisting of the frame of the crosswise feeding mechanism and an immovable part, with the attachment-engaging portions being not only connected to the other member selected from said group but also capable of rotating relative to said other member.
