A tray shuttle and a tray conveyor using the tray shuttle to route magnetic conveyor trays from one conveyor section to another. The trays and the shuttles are propelled by linear-motor stators that produce electromagnetic flux waves that interact with the magnetic fields of permanent-magnet arrays in movers in each tray. Each shuttle has a main holder mover and one or more other movers connected to a linkage that operates one or more pushers that push trays off a tray holder on the shuttles.

A device for a shelf system for load carriers for securing a shuttle before leaving its running rail at the end of an aisle of the shelf system, wherein the device comprises a retaining element, the retaining element having a flexible element. A shelf system and a shuttle are also provided.

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 warehouse storage and retrieval system including an array of multilevel storage racks having at least one transfer deck, picking isles and storage areas disposed along picking isles, the storage areas being configured to hold differing loads, and a controller including a management module configured to variably size the storage areas of the array of multilevel storage rack modules and assign each of the variably sized storage areas to a corresponding one of the differing loads, wherein the storage and retrieval system is arranged to transport the differing loads for placement in the variably sized storage areas assigned by the controller.

This disclosure is directed to automated warehouse facilities that are configured to assemble mixed pallets. The warehouse facilities can include one or more layer handling devices that are configured to remove layers from pallets in a delayering operational mode, and to add layers to pallets in a palletizing operation mode. The warehouse facilities also may include one or more item retrieval devices that are configured to retrieve individual items from storage racks. The warehouse facilities can include other automated devices as well.

In general, the subject matter described in this disclosure can be embodied in a multi-level pallet-conveying system for a storage facility. The conveying system includes a first-level conveying system, a first-level into-storage conveying lane adapted to receive pallets from the first-level conveying system and provide such pallets to a first-level station of a storage lifting system, and a first-level from-storage conveying lane adapted to receive pallets from the first-level station of the storage lifting system and provide such pallets to the first-level conveying system. The conveying system also includes a second-level conveying system, a second-level into-storage conveying lane adapted to receive pallets from the second-level conveying system and provide such pallets to a second-level station of the storage lifting system, and a second-level from-storage conveying lane adapted to receive pallets from the second-level station of the storage lifting system and provide such pallets to the second-level conveying system.

In general, the subject matter described in this disclosure can be embodied in a pallet-conveying system. The pallet-conveying system includes a vehicle-traversing loop, multiple vehicles configured to travel around the vehicle-traversing loop and move pallets around the vehicle-traversing loop, an inbound conveying lane arranged to move inbound pallets from a docking area to the vehicle-traversing loop, multiple outbound conveying lanes arranged to transfer pallets from the vehicle-traversing loop to the docking area, an into-storage conveying lane arranged to move pallets from the vehicle-traversing loop to a storage area, a from-storage conveying lane arranged to move pallets from the storage area to the vehicle-traversing loop, and multiple pallet stands located within an interior of the vehicle-traversing loop to receive pallets from the multiple vehicles.

A conveyor carriage movable on a guide rail. The conveyor carriage includes a conveyor frame; a pair of side rails spaced apart from each other; and a load carrying portion coupled to the pair of side rails. A drop-down plate hingedly mounted to the conveyor frame and positioned in between the pair of side rails. The drop-down plate is pivotable between an open position and a closed position, wherein the drop-down plate encloses a component of the conveyor carriage in the closed position. The conveyor carriage to pick up and deposit loads from and to a load handling station. The load handling station including a control box with a pivotable lid to enclose one or more components of the load handling station in the closed position.

A transfer robot comprises a movable chassis, a door frame vertically arranged on the movable chassis, and a temporary storage mechanism and a cargo box conveying mechanism which are arranged on the door frame, wherein the temporary storage mechanism is provided with a plurality of temporary storage spaces used for temporarily storing cargo boxes, and the cargo box conveying mechanism can stretch horizontally and lift vertically relative to the door frame so as to convey the cargo boxes between the temporary storage space and a temporary inventory container.

An automated storage and retrieval system for storing product items includes a framework structure with upright members and horizontal members and a storage volume including storage columns between the members. The framework structure includes a rail system arranged above the members. The automated storage and retrieval system further includes storage containers in which the product items are stored and container handling vehicles moving along the rail system for transporting the storage containers. The storage containers are stackable in stacks within the storage columns. The rail system includes rails and each rail includes tracks. Adjacent tracks of at least one rail of the rail system are separated by a ventilation slot extending in a vertical plane between two adjacent storage columns.
