An article sortation system includes a plurality of transport units which are movable along a conveying path between induction stations and discharge stations along each side of the conveying path. Each transport unit has side by side loading and support capability and is operable to receive packages from induction stations and discharge the packages at an appropriate discharge station. The system includes a control which determines the destination of articles and resolves blocking conditions between articles at the induction stations or at the transport units. The system may include a reinduction station for receiving an article from a transport unit and reinducting the article onto a transport unit, in order to resolve a blocking condition between a pair of articles on the respective transport unit.

Article sortation system

A sortation system and method of inducting product are useful with a sorter having a continuous member defining a plurality of transport positions of the continuous member and a plurality of sort destinations for receiving product discharged from the continuous member. At least one induction unit is provided including a plurality of tandem conveying units. Product is received with the at least one induction unit from a product source and discharged from the at least one induction unit to the continuous member. The invention is useful with carousel sorters, such as tilt-tray sorters and cross-belt sorters.

High rate induction system

A sortation system and method of inducting product are useful with a sorter having a continuous member defining a plurality of transport positions of the continuous member and a plurality of sort destinations for receiving product discharged from the continuous member. At least one induction unit is provided including a plurality of tandem conveying units. Product is received with the at least one induction unit from a product source and discharged from the at least one induction unit to the continuous member. According to one aspect of the invention, the at least one induction unit follows the speed of the continuous member. This includes starting as soon as the continuous member is moving and decreasing in speed substantially only when the continuous member decreases in speed. The invention is useful with linear sorters, such as positive displacement sorters, and the like. The invention is also useful with carousel sorters, such as tilt-tray sorters and cross-belt sorters.

A sortation system includes a plurality of transport units movable along a conveying path. Each of the transport units is capable of carrying side-by-side articles thereon. The plurality of carriages pass at least one induction station and at least one discharge station along the conveying path. Each of the carriages is capable of transferring an article from one side of the carriage to the other side of the carriage. Each of the carriages may be capable of receiving an article on one side of the carriage when another article is already positioned on the other side of the carriage, and/or may be capable of substantially simultaneously discharging side-by-side articles to discharge stations at opposite sides of the conveying path, and/or may be capable of receiving an article on one side of the carriage without moving an article already positioned on the carriage.

Double width sorter

A crossbelt sortation system is provided which includes a pair of side-by-side carrier belts on each of a plurality of transport units movable along a conveying path. The carrier belts may be operable independently or in a synchronized manner, in order to receive packages from one or more induction stations and either discharge the packages at an appropriate discharge station or transfer the package onto the carrier belt at the other side of the transport unit. A control system is operable to determine the destination side of the packages at the induction station and to further determine the availability and appropriateness of the carrier belts of the approaching transport units, in order to determine if an available carrier belt is proper or compatible to receive the next package at the induction station. The present invention thus effectively provides presortation of the packages as they are inducted onto the transport units, such that optimal throughput rates are achieved without the complex presortation processes implemented with the prior art systems. Additionally, the carrier belts of one or two adjacent transport units may be synchronously operated to receive larger packages across the side-by-side carrier belts of a single unit or to receive oversized packages or products at the carrier belts of a pair of adjacent transport units. The carrier belts may be synchronously operated to receive a package and pivot the package as it is inducted onto the transport units, in order to properly orient the package on the transport unit or units. The packages or products may then be discharged at an appropriate discharge chute in a similar manner.
