A divert chute and a sorting conveyor system having divert chutes that include an array of high-friction rollers in a landing zone to resist the cross-chute momentum of parcels diverted off the sorting conveyor at high speeds. The rollers, which protrude above a flat slide region of the chute, rotate only in a direction down the chute. Parcels sliding axially along the high-friction rollers across the chute are slowed or stopped in the cross-chute direction while being redirected down the chute.

An automated storage and retrieval system includes a rail system comprising a first set of parallel rails arranged to guide movement of a container handling vehicle in a first direction across the top of a framework structure, and a second set of parallel rails arranged perpendicular to the first set of rails to guide movement of the container handling vehicle in a second direction. The second direction is perpendicular to the first direction. The first and second sets of parallel rails divide the rail system into a plurality of grid cells. The framework structure includes upright members and horizontal members. At least one container handling vehicle is configured to operate on the rail system. The at least one container handling vehicle is provided with at least one orientation sensor configured to measure at least one orientation parameter of the sensor in a three-dimensional cartesian reference system. A central control unit is configured to receive, transmit and process data signals of the container handling vehicle and to receive and process data signals of the sensor. At least one container is comprised of four side walls and a bottom creating an open box structure. The container is transported to an unloading station where the content of the container is emptied by gravity. The unloading station includes a container rotating device that rotate the container around at least one axis, emptying the required amount of content, and the container rotating device includes a guide surface which guides the container along a helical path.

A divert chute and a sorting conveyor system having divert chutes that include an array of high-friction rollers in a landing zone to resist the cross-chute momentum of parcels diverted off the sorting conveyor at high speeds. The rollers, which protrude above a flat slide region of the chute, rotate only in a direction down the chute. Parcels sliding axially along the high-friction rollers across the chute are slowed or stopped in the cross-chute direction while being redirected down the chute.

Disclosed are various embodiments for robotic item sortation and optimization along the vertical axis in a conveyor-based system. A robotic system may be mounted above or adjacent to a conveyor system that moves items along a conveyor belt or similar device. Once an item is laterally diverted from the conveyor system, the robotic system may collect the item at a respective holding station and move the item along a vertical axis for placement in one of a plurality of vertically-configured item handling devices.

A modular chute system includes a support bridge having a main body and a plurality of mounting plates spaced apart along the main body. The support bridge has a first end configured to be secured to an infeed component and a second end configured to be secured to a discharge component. The system includes a plurality of ribs, each having an outer portion and an inner portion, where the plurality of ribs is secured to the plurality of mounting plates. The system also includes an inner lining secured across the inner portion of the plurality of ribs, and a plurality of panels each having a mounting bracket on a proximal end secured between the outer portion of adjacent ribs using the mounting bracket. A distal end of each panel is secured through a respective anchor slot to form a continuous sliding surface from the infeed component to the discharge component.

A feed unit for articles includes a guide extending along a guide longitudinal axis to define a linear feed path for such articles. The guide is for accommodating articles arranged in a row one after the other and to guide the articles as the articles move along the linear feed path. The articles have a characteristic length corresponding to their size along the longitudinal axis. At least one segment of the guide is progressively rotated about the guide longitudinal axis by a total angle greater than 180 and with an angular variation per unit of linear measurement such that, substantially for each portion of the linear feed path equal to the characteristic length of the articles, the guide is rotated about the longitudinal axis by an angle greater than 4.

A system for holding one or more bags. The system includes a cart, a first chute disposed on the cart, and a second chute also disposed on the cart. The first chute includes a first edging along each side of the first chute. The second chute includes a second edging along each side of the second chute. The second chute is intertwined with the first chute. The system may further include a third chute and a fourth chute disposed on the cart. The third chute may include a third edging along each side of the third chute, and the fourth chute may include a fourth edging along each side of the fourth chute. The top and bottom of the first chute and the top and bottom of the second chute are positioned on opposite ends of the cart at about 180 degrees apart, while the top and bottom of the third chute and the top and bottom of the fourth chute are positioned on opposite ends of the cart at about 180 degrees apart.

Provided are a helically traveling carriage and a helically traveling cleaning machine capable of efficiently performing a maintenance process, such as cleaning, with respect to a helical structure formed by winding a helical wall around a column at a central section of a vertically extending cylindrical wall. This helically traveling carriage includes a lower moving-and-contacting part that rolls or slides on a helical wall's upper surface, a lateral bridge mechanism that bridges a column's outer circumferential surface and a cylindrical wall's inner circumferential surface, the lateral bridge mechanism having, on one end thereof, a first moving-and-contacting part that rolls or slides on the cylindrical wall's inner circumferential surface, and having, on the other end, a second moving-and-contacting part that rolls or slides on the column's outer circumferential surface, and a rotary engagement part that rotatably engages with the column by laterally receiving a portion of the column.

Described are systems, methods, and apparatus for managing the movement of inventory items within a materials handling facility using rollable containers and a gravity feed conveyance system. Inventory items are placed in the rollable containers and are routed to different locations within the materials handling facility along the gravity feed conveyance system, through use of gravitational forces that cause the rollable containers to roll. By using gravity to route inventory items within the materials handling facility, the energy and power requirements for the materials handling facility are reduced, which reduces overhead costs and which is better for the environment.
