Various embodiments described herein, relates to a sortation conveyer system comprising a cart coupling assembly for coupling two adjacent carts. The cart coupling assembly includes a coupling disc having: (a) a control slot, (b) a bearing slot, and (c) one or more arcuately shaped mounting slots. The coupling disc is mounted on a cart such that, upon rotation of the coupling disc, a control slot cavity defined by the control slot slid ably moves about a position register screw along the control slot cavity and a cavity defined by a respective mounting slot slid ably moves relative to a respective mounting pin received in the mounting slot.

A conveying device (1) has conveying carts (2) arranged one behind another and spaced apart by an interspace (4). One conveying cart (2) has a cover (6) and another has a cross-belt conveyor (8) for conveying material transverse to the conveying direction. The cover (6) covers the interspace (4) between the conveying carts (2) so that the cover (6) of the one conveying cart (2) is under the upper run (21) of the transverse belt (10) of the other conveying cart (2). When negotiating curves, the cover (6) engages between an underside (22) of the upper run (21) and a first support plane (20) to hinder the transverse belt (10) from moving in the transverse conveying direction. When travelling straight ahead the cover (6) engages between the first support plane (20) and a second support plane (24) to permit movement of the transverse belt (10) in the transverse conveying direction.

A modular transfer system with a primary flow system and a diverter system. The primary flow system includes a primary flow belt for conveying an article along a primary flow path from an infeed side of the modular transfer system to a pass-through side of the modular transfer system. The diverter system includes one or more diverter belts for diverting an article from the primary flow path towards a divert side of the modular transfer system. The primary flow belt includes multiple movable components contacting the diverter belt. The movable components can have one or more rotational degrees of freedom.

A destacking conveyor having a conveyor belt with pushers selectively pushing stacked packages transverse to the conveying direction to one side of the conveyor against a vertical wall with a gap between the bottom of the wall and the belt to block the top package of a stack and allow the bottom package to pass through the gap and off the side of the belt to a reject bin. In another version a destacking conveyor uses a force applicator to apply a downward force against the top of a stack to hold the top package while the pushers slide the bottom package from under the top package.

A conveyor system is provided. Conveyor modules are pivotally secured to one another through engagement of links on a first and second side of each module. Portals extend through the modules. Each portal comprises four portal surfaces oriented in opposing pairs. A radial slot is located on each of at least two portal surfaces. A cup is provided with four walls. Ridges are formed on the outside surfaces of at least two opposing walls of the cup. An orifice is formed on two opposing walls of the cup. A roller is rotatably mounted on an axle that extends between the orifices to position the roller inside the cup. The cup is secured inside the portal by engagement of the ridges with the slots. The cup and roller assembly may be rotated to change its orientation relative to the module.

A tray assembly is provided for use with a carrier in a product sortation system. The tray assembly includes a platform to receive parcels loaded onto the carrier. A pair of movable edge members are disposed at opposite sides of the platform. Each edge member is integrated with a combination including a pair of pivotable support arms and a spring element intermediate of the support arms. Each support arm supports its edge member at one end and is pivotally mounted at another end to a tray framework. The spring element is fixedly mounted at one end to the tray framework and is connected at another end to its edge member in a biasing relationship. In response to an applied load resulting from a parcel bearing down on the edge member, the support arms pivot downward in a manner sufficient to allow the parcel to reach and then rest on the tray platform. At the same time as the support arms pivot, the spring element deflects. After the package is unloaded from the tray platform, the return action of the spring restores the edge members back to their original location, as guided by the support arms.

In one embodiment, a sortation system at a facility has a conveyor system and a mobile drive unit system. The conveyor system has a conveyor surface that transfers payloads to the mobile drive units, and a controller that communicates a payload identifier for each payload to the mobile drive unit system. The payload identifiers are masked such that information about the local destinations are unknown to the conveyor system. The mobile drive unit system determines the local destinations from the payload identifiers by unmasking the payload identifiers, and delivers the payloads to determined local destinations at the facility.
