A conveyance method of conveying a conveyance target object by loading the conveyance target object on a slider, wherein the slider is connected to a ball nut threadably engaged with a ball screw shaft, includes a step of rotating the ball screw shaft by an electric motor, a step of applying a braking force which is a rotation resistance to the ball screw shaft by a non-electric resistance changing unit, and a step of setting at least one of a driving force of the electric motor and the braking force of the resistance changing unit so that the slider will stop when a predetermined external force acts on the slider during conveyance and changes the slider to an overload state regardless of the presence/absence of the conveyance target object loaded on the slider and a weight of the conveyance target object.

A drive unit for an endless conveyor, comprising a magnetic transmission and an electric motor connected to an input shaft of the magnetic transmission, where the magnetic transmission comprises a rotatable outer cylinder comprising a plurality of permanent magnets arranged as magnetic poles at the inner side of the outer cylinder, an intermediate cylindrical element comprising a plurality of ferromagnetic pole pieces, an inner cylinder comprising a plurality of permanent magnets arranged as magnetic poles at the outer side of the inner cylinder, where the outer side of the outer cylinder is configured with a drive surface adapted to interact with a conveyor belt or conveyor chain. The advantage of the invention is that a compact and efficient drive unit for a conveyor system is provided, which is provided with a contactless predefined slip.

Conveyor arrangement, adapted for taking over a conveyed object, in particular a postal parcel, at a takeover area, in particular from an upstream feed device, for transferring the conveyed object at a transfer area, in particular to a terminal; for transferring the conveyed object in a chute area from the takeover area to the transfer area, wherein the chute region comprises at least one chute which is inclined downwardly in the conveying direction and on which the conveyed object is conveyed in a gravitationally sliding manner, wherein the chute region comprises a belt conveyor with a conveyor belt, characterized in that the belt conveyor has a holding brake which is adapted to hold the conveyor belt in a stop position.

A tensioning mechanism for a conveyor system includes a support structure, a first carriage, a second carriage, and a brake mechanism. The first carriage is positioned proximate a first end of the support structure and is supported for movement relative to the support structure. The first carriage includes first rolls for receiving the belt such that movement of the first carriage modifies a tension in the belt. The second carriage is supported for movement relative to the support structure and includes second rolls and at least one return pulley. The second rolls are configured to support a portion of the belt extending between the first carriage and the second carriage. The brake mechanism is positioned proximate a second end of the support structure and includes a brake pulley and a brake selectively retarding rotation of the brake pulley. The brake pulley supports a portion of the belt extending between the brake mechanism and the return pulley.
