A positive displacement sorter and method of diverting articles includes a conveying surface configured to convey articles in a longitudinal direction and at least one diagonal take-away lane, extending diagonally from the conveying surface to receive articles being diverted from said conveying surface. A plurality of pushers are configured to move together in a lateral direction in order to displace an item on the conveying surface to the diagonal take-away lane. A rotational system is configured to rotate a leading portion of a diverted article in the direction of the take-away lane. A belt drive system is provided for driving live roller conveyors about a curved section of a roller conveyor of the sorter. The drive belt is guided along a single conical drive plane that maintains the orientation of the drive belt relative to the single conical drive plane and limits twisting and stress in the drive belt.

A conveyor apparatus includes a supporting plate and a conveyor module. The supporting plate is connected to the conveyor module. The supporting plate includes a first power and communication terminal that is configured to provide the conveyor module with power and a communication connection. The conveyor module is connected to the supporting plate. The conveyor module is detachable and includes a second power and communication terminal that is connected to the first power and communication terminal to receive the power and to perform the communication connection. The first and second power and communication terminals are detachable, with an ability to be connected to and disconnected from each other.

A curved conveyor in a horizontal curved path section of a conveying path has an inner idler wheel array arranged to the inside of the horizontal curved path section with respect to an arc-shaped center line that passes through the center of the path width of the horizontal curved path section, and an outer driving wheel array arranged to the outside of the horizontal curved path section with respect to the arc-shaped center line, wherein the distance from the arc-shaped center line to the outer driving wheel array is smaller than the distance from the arc-shaped center line to the inner idler wheel array.

A conveyor bed including a conveyor frame, a first set of rollers, a second set of rollers, and a pivotable frame is provided. The first set of rollers are coupled to the conveyor frame to transport an article from an upstream location to a downstream location. The pivotable frame pivotably coupled to a side of the of the conveyor frame. The second set of rollers mounted to the pivotable frame, positioned below the first set of rollers. A belt wrapped is around the second set of rollers, and selectively engages and disengages the first set of rollers in response to pivoting the pivotable frame based on predefined criteria.
