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.

A direction switching module for lift robots using a pair of pinions coupled to a rack for propelling vertically and horizontally according to the track's orientation, is disclosed. In a linear motion mode both pinions rotate in the same velocity. In a direction switching mode, when changing from vertical to horizontal motion mode and vise versa, the module is capable of propelling one pinion on a vertical track and its counterpart on a horizontal track, simultaneously, each pinion in a different velocity. A bogie propelled by two pairs of said module is also disclosed, and a controller configured to drive both pinions in same velocity during linear motion and each pinion in a separate appropriate velocity during the direction switching mode. A method for turning a pinion-driven lift-robot in an intersection of rails and a controller for controlling the linear motion modes and the direction switching modes of the lift robot are also disclosed.

A vehicle tilting device for tilting a delivery vehicle for increasing access to items from a storage container transported on the delivery vehicle. The vehicle tilting device comprises a base structure and a tiltable platform connected to the base structure, wherein the tiltable platform comprises guiding features adapted to guide the delivery vehicle onto the tiltable platform. The tiltable platform is arranged to be connected to a delivery grid cell of a delivery rail system such that that there is a path to and/or from the tiltable platform for the delivery vehicle via the delivery grid cell. The invention is also related to an access station, a delivery system and a method of accessing a storage container.

A load handling device for lifting and moving one or more containers stacked in a storage system with a grid framework structure supporting a plurality of tracks arranged in a grid pattern, the load handling device comprising: A) a driving mechanism; and B) a vehicle body having a footprint that occupies a single grid cell in the storage system, the vehicle body housing including: i) a rechargeable power source; ii) a first space configured for accommodating a container and the rechargeable power source is housed in a second space; and iii) a lifting device to releasably grip a container and lift the container from the stack into the first space, wherein the rechargeable power source is arranged above the first space such that the centre of mass of the load handling device is in the second space.

An automated temperature-controlled outdoor terminal for storage and handover of online grocery orders allowing simultaneous operation of two transactions and a method to operate the terminal is described here.

Systems and methods can enhance efficiencies of order fulfillment processes. For example, this document describes systems and methods for optimizing the efficiency of order sortation processes to expedite order processing in a cost-effective manner. The systems and methods facilitate high utilization of labor due to reductions in wasted movements and even loading of workers of a team of workers. Additionally, the systems and methods promote efficiency enhancements of order sortation equipment by reducing the potential for downtime due to material flow interferences.

A grid framework structure includes: first and second sets of parallel rails or tracks forming a grid pattern with grid spaces. The grid is supported by a set of uprights to form vertical storage locations beneath the grid for containers to be stacked. A load handling device includes: a lifting assembly having a sling assembly arranged to support, raise and lower a load, the sling assembly having: a sling extending between a support mountable to a body of the load handling device and a gripper plate for supporting the load. First and second ends of the sling are attached to first and second hoist drums.

A vehicle body frame includes a first rib protruding from a bottom surface portion toward an upper side and extending along a first direction. A vehicle body cover includes a second rib protruding from a top surface portion toward a lower side and extending along a second direction. A lower frame portion of a holding member that holds a power storage body includes a first recessed groove portion recessed from a lower end surface toward the upper side and extending along the first direction. An upper frame portion of the holding member includes a second recessed groove portion recessed from an upper end surface toward the lower side and extending along the second direction. A power storage unit is sandwiched between the bottom surface portion of the vehicle body frame and the top surface portion of the vehicle body cover.

A placement body on which an article is placed is driven by a transfer drive mechanism to transfer the article. The transfer drive mechanism includes a transfer drive source and a transmission mechanism. The transmission mechanism includes an output member coupled to an output shaft of the transfer drive source and a driven member that is not coupled to the output member and operates by being pressed by the output member. A wheel drive source, the transfer drive source, and the output member are supported by a vehicle body frame, and the placement body and the driven member are supported by a vehicle body cover. The vehicle body cover covers the wheel drive source and the transfer drive source and is detachably attached to the vehicle body frame.

A swing arm changes a position of a placement surface of a placement body between a horizontal position and a tilted position by swinging between a reference position at which the swing arm extends along an opposing surface facing a lower surface of the placement body and a standing position at which the swing arm is tilted relative to the opposing surface. The opposing surface is provided with a guide member configured to guide swinging movement of the swing arm, and the guide member is configured to support the swing arm by sandwiching the swing arm from both sides in an axial direction within a prescribed guide range including the reference position in a total swing range of the swing arm.
