A method and apparatus are provided for storing and retrieving items to/from a plurality of destinations areas. A storage and retrieval system stores and retrieves items as needed and transfer items from storage locations to transfer locations. A separate picking system conveys the items from the transfer locations to a picking station or an input out station so that the item can be selected.

An apparatus is disclosed including a robotic system having a robotic picking workstation, tote storage and retrieval and transit decks. The system has bots that autonomously transport totes from the storage and retrieval system to the robotic picking workstation via the transit decks. The robotic picking workstation may have a picking lane where a robotic handler transports eaches from totes on the bots to order totes in the workstation. The robotic picking workstation further has a queuing buffer where bots are cued for the picking lane.

An automatic storage and retrieval system includes: a delivery vehicle; a storage container carried by the delivery vehicle; and an unloading station for unloading an item from the storage container while it is being carried by the delivery vehicle. The unloading station includes: an unloading device; and a destination conveyor configured to convey the item to a target destination, wherein the unloading device is configured to move the item through a side opening of the storage container to the destination conveyor.

A mechanised container for use in a robotic storage and picking system is described. The container includes a base openable to deposit at least one item from the container in to a further container positioned by a load handling device beneath the first container. Each item can be stored in such mechanised containers in stacks within a robotic storage and picking system.

A drive belt assembly for a load handling device includes a drive belt; a drive wheel; and one or more driven wheels. A first tensioning arm, having a fixed end above an elbow and a rotatable distal end pivotally attached at the elbow, is horizontally displaceable relative to the drive wheel and driven wheels. A second tensioning arm is provided wherein the drive belt is routed around the first and second tensioning arms, and the first and second tensioning arms are arranged to put pressure on the drive belt to tension the drive belt.

A transfer device includes a first hook and a second hook. The first hook has a first side-edge section, which is an end edge on a second side in the width direction in a first retreat position. A partial region of the first side-edge section that includes at least a first leading-end section has a shape that is curved or bent to gradually extend toward the first side in the width direction while extending toward the first leading-end section. The second hook has a second side-edge section, which is an end edge on the first side in the width direction in a second retreat position. A partial region of the second side-edge section that includes at least a second leading-end section has a shape that is curved or bent to gradually extend toward the second side in the width direction while extending toward the second leading-end section.

A two-dimensional rail system includes a first set of parallel rails arranged to guide movement of container handling vehicles in a first direction across the top of the frame structure, and a second set of parallel rails arranged perpendicular to the first set of rails to guide movement of the container handling vehicles in a second direction which is perpendicular to the first direction. The first and second sets of parallel rails dividing the rail system into a plurality of grid cells. A container handling vehicle for operation on the rail system includes a wheel base unit including sets of wheels for guiding the container handling vehicle along the rail system in the first and second directions; a body unit; and a lifting device. The body unit includes: a lower section which is provided on the wheel base unit; a support section extending vertically from the lower section; and a cantilever section extending horizontally from the support section. The lower section has a footprint with a horizontal extent which is equal to or less than the horizontal extent of one of the grid cells and a top surface which is at a first height. The support section has a footprint with a horizontal extent which is smaller than the footprint of the lower section. The cantilever section extends beyond the footprint of the lower section. The lifting device includes a lifting frame that is suspended from the cantilever section of the body unit. The lifting frame has a lowermost part at a second height when the lifting frame is docked in an upper position adjacent the cantilever section. The second height of the lowermost part of the lifting frame, when the lifting frame is docked in its upper position, is above the first height of the top surface of the lower section of the body unit.

A device for picking or depositing an item from or into a compartment of an automated warehouse has first moving means for moving the device along a main direction and primary electrical power supply means having a pair of forks moved by second moving means along a transverse direction between a retracted position and an extended position. Each fork has an end section having at least one thrust element movable between an operating position and an idle position. The end section has third moving means for moving the at least one thrust element. A central control unit commands moving parts of the device. The end section has a peripheral control unit for the third moving means. The end section has rechargeable secondary electrical power supply means for supplying power to the peripheral control unit and to the third moving means.

A delivery vehicle operates on a two-dimensional rail system with rails extending in a first direction and a second direction. The second direction is perpendicular to the first direction. The delivery vehicle includes a vehicle body; two sets of wheels connected to the vehicle body for engagement with the underlying rail system and for moving the delivery vehicle in the first and second directions; a container carrier for supporting a container from below, wherein the container carrier comprises a first conveyor; a conveyor drive shaft for driving the first conveyor; and at least one drive coupling. The at least one drive coupling includes a connection interface accessible from an outer side portion of the vehicle body. The drive coupling is rotatably connected to a motor drive shaft such that when the motor drive shaft is rotated the drive coupling and the connection interface are rotated.

Movement is controlled of a plurality of container handling vehicles on a rail system arranged at least partially across a top of a framework structure of an automated storage and retrieval system, on which rail system the plurality of container handling vehicles are operable to raise storage containers from, and lower storage containers into, storage columns arranged in rows between upright members and horizontal members of the framework structure. The storage containers are also transported above the storage columns. The movement control is performed by a central operational controller which is in communication with a local controller in each container handling vehicle. The central operational controller receives data relating to a subsection of the rail system. The data includes a container handling vehicle movement threshold for the subsection. The central operational controller instructs a container handling vehicle to follow a path which takes in at least a part of the subsection. The central operational controller instructs the container handling vehicle to reduce speed and/or acceleration such that the movement of the container handling vehicle within the subsection is below the container handling vehicle movement threshold of the sub section.
