A right angle transfer device has a conveying surface defined by a plurality of conveying members that are driven to convey objects in a conveyance direction. A diverting conveying member is mounted to a frame and is driven to divert objects in a direction angled away from the conveyance direction. A lift drive rotates a cam to move a bar in a substantially horizontal direction. The movement of the bar causes a frame link connected to the bar and the frame to raise and lower the frame. Once the frame has been moved upward to a sufficient extent, the diverting conveying member will be raised above the conveying members to come into contact with the object to thereby move and divert the object away from the conveyance direction.

A method and system for fulfilling customer orders having a data base that is adapted to store a plurality of customer orders and identity of warehouse inventory items and return inventory items that make up each of the customer orders. Some of the orders are single item orders with only one inventory item assigned to that order. Some of the orders are multiple item orders with multiple inventory items assigned to that order. Returned items that are processed and determined to be acceptable to be re-distributed are re-introduced into the inventory data base and are available to be assigned to an order. Warehouse inventory and return inventory are maintained independent of each other to reduce redundant operations. The order fulfilment system retrieves items from either or both of the warehouse inventory and return inventory to fulfil customer orders. The order fulfilment system may utilizes human associates or robot associates.

A de-traying method and apparatus for removing articles from trays, each of the trays having a base, a rim around the base and an opening in said base and a bottom covering said opening and liftable from said base. A tray supporting an article is transported to a detraying assembly where the article is detrayed by elevating the bottom at least to the level of the tray rim with an article lifter having a lifting base and a plurality of lifting blocks. The lifting blocks are sized and arranged to engage the tray bottom through the opening in response to the lifting base being elevated, and to maintain orientation of the tray with at least one of said blocks positioned outside of the tray adjacent the rim. The article is displaced off of the elevated tray bottom.

Methods are provided for optimizing retail inventory receiving and putaway processes within a retail store. The methods include segregating items from inbound inventory loads by unloading and identifying each of the items in the load. Based on the identity of an item, a computer directs the operator to segregate each item to a putwall, such as to a container on a mobile inventory cart. A pick to light (PTL) system is utilized to direct the operator's segregation processes. Each item is segregated into a family or sub-family grouping of inventory items that correspond to a particular department or sub-department of the retail floor of the store. Segregated family or sub-family groupings are distributed to respective departments to be putaway by an associate on the retail floor. The methods may be adapted to process e-commerce orders for shipment out of the store or for in-store customer pickup.

An assessment system and method are provided for determining whether an item handled in a material handling system is stable and conveyable or unstable and non-conveyable. If an item is deemed non-conveyable, it is diverted or otherwise removed from the material handling system before it is transported downstream where it may affect the operation of the system or cause damage to the system and/or item. The system utilizes a dimension sensor system, such as including photo arrays, to measure contact region dimensions between an item being conveyed and the conveyor surface. The contact region is observed under constant conveyance rates, accelerating conveyance rates, and decelerating conveyance rates to determine whether the item orientation changes due to shifts in momentum. Any measured contact region changes are compared to a maximum allowed value, and if the measured change is greater than the maximum, the item is deemed non-conveyable.

A network module configured to provide switched auxiliary (AUX) power for E-stop system functionality in a network system. The network module includes a switching module and a controller. The switching module is configured to control the passage of power through a switched AUX cable for E-stop functionality. The switching module is configured to receive an unswitched AUX cable and the switched AUX cable. The controller is communicatively coupled to a communications cable. The controller is configured to control the switching actions of the switching module as defined by switching instructions received via the communications cable.

A system and method are provided for auditing the inventory within an automated warehouse utilizing RFID technology. The system and method enable real-time tracking and monitoring of inventory and load units as they travel through and are stored in the warehouse. The system may require only a single RFID reader coupled with an automated shuttle for traversing a majority of the warehouse storage system to read, recognize, and audit the inventory as stored in load units stored in the system. The system may utilize multiple RFID readers throughout the warehouse to provide ample coverage, enabling real-time, whole warehouse inventory tracking. The system and method of the present invention contemplate both readily available RFID technologies, as well as advanced or improved RFID technologies having greater detection range, larger information storage capabilities, and the ability to determine precise spatial location of tags relative a reader.

An RFID enabled system and method for tracking, directing, verifying, and validating item level order picking functions within order fulfilment and warehouse facilities having different SKUs sharing an inventory tote. RFID tags are coupled to each inventory item to be read by one or more RFID reader(s) in the facility. The system and method verify that a required item is picked and transferred correctly by the picker. The system provides feedback to the picker without requiring additional verification steps and preferably without any visual inspection by the picker. The picker may be guided to the required item and later directed to a location to place the retrieved item. The verification system may be adapted for use in a material handling system to monitor and direct material handling functions based on relative positions of RFID tags on individual items relative to RFID readers positioned throughout the facility.

A sound attenuated material handling element reduces vibration and sound in a material handling system. The material handling element may be a sound attenuated roller for use in a roller conveyer or a sound attenuated nestable tote for receiving and transporting articles in the material handling system. Reducing vibration in material handling element reduces the noise produced by the element. The sound attenuated roller includes sound attenuating material disposed inside of the roller and in contact with the inner surface of the roller body. The sound attenuated nestable tote includes sound dampening material disposed in or formed with the tote structure. The sound damping material may be integrally formed with the roller or tote in order to maximize vibration and noise attenuation. Three dimensional computer analysis may be used to determine optimized locations for placement of the sound damping material on the roller or tote.

A dynamic storage wall with reconfigurable storage cubbies and methods of operating the storage wall are provided for a storage facility. The storage wall includes a shelf with multiple storage cubbies and one or more repositionable dividers defining boundaries between the cubbies. The storage wall includes a Time of Flight (ToF) sensor array adjacent to the shelf for measuring positions of each of the repositionable dividers. The ToF is also adapted for recognizing when an item has been retrieved from or placed at either of said storage locations. A workflow control system with a computer is connected to the sensor array. The control system utilizes data from the ToF sensor array to determine when a repositionable divider has been moved and/or when an item has been retrieved from a storage location. The system may automatically or manually recognize when a divider is moved and that new measurement is required.
