Abstract
An overhead conveyor system with an elongate box girder (9) having a first inner space with rails (12) and a second elongate inner space comprising an endless driven drive element (5, 6) is provided with at least one carrier (14, 14′) adapted to run on said rails (12) wherein said carrier is provided with an elongated body (C) supporting at least one friction driver (15), wherein said at least one friction driver is in the form of a friction arm assembly (19) with an upper end (20), a lower end (21) and an intermediate portion (22) between said upper and lower ends, said upper end comprising a friction shoe (25) adapted to be pressed upwards by the force of gravity towards engagement with the drive element (5) so as to transfer drive to the carrier.
Claims18
A carrier for use in an overhead conveyor system comprising an endless drive element for driving a carrier in a forward direction,
- wherein said carrier is provided with an elongated body with a front end and a rear end supporting at least one friction driver,
- wherein said at least one friction driver is in the form of a friction arm assembly with an upper end and a lower end, and said upper end comprising a friction shoe,
- wherein said friction arm assembly is arranged to pivot with respect to the carrier around a horizontal pivot axis arranged substantially transverse to the longitudinal axis of the elongated body, and
- wherein said friction shoe is biased upwards by the force of gravity due to:
- i) the centre of gravity of the friction arm assembly being below the horizontal pivot axis and/or,
- ii) the centre of gravity of the friction arm assembly being displaced in one direction along the longitudinal axis of the elongated body from the horizontal pivot axis while the friction shoe is displaced in the opposition direction along the longitudinal axis of the body from the horizontal pivot axis.
