International Classification:

G01B 7/30

US Classification:

3242072

Abstract:

An encoder is provided for a conveyor having a belt, a plurality of rollers supporting the belt and a motor for driving one of the rollers. The encoder includes a hall effect cartridge having at least one hall effect sensor. The hall effect cartridge is adapted to be mounted inside of one of the rollers supporting the conveyor.

International Classification:

G06Q 10/08

Abstract:

A time tracking and indicator system and method are provided for tracking and indicating initialization-to-completion times for order fulfilment operations, such as order packaging and shipping operations. The system includes a put-wall with multiple order storage locations and indicators at each of the storage locations. The indicators are independently addressable by a computer and may include color changeable lights and/or alphanumeric displays. The method and system provide visual prompts to an operator of the put-wall to indicate multiple statuses for an order at a particular storage location. Prompts include indications that (i) an order is ready to be attended to, (ii) an operation time limit has been exceeded, and (iii) that an operation for that location is exceedingly overdue. Time limits and prompts may be preset by a user or may be automatically set and adjusted by the computer based on historic operation completion times.

International Classification:

B07C 5/36
B65G 47/84
B65G 43/00

Abstract:

A method of sorting articles with a sorter apparatus and a sorter apparatus having a conveying surface that is adapted to transport articles in a direction of conveyance and a mechanism adapted to displace articles on the conveying surface, the sorter apparatus having an endless web of bodies travelling in an endless loop defining the conveying surface includes a distributed drive system having at least one drive that is adapted to produce to provide force with at least one of the bodies to propel the endless web. A diagnostic device traveling with the web and positioned at one of the bodies of the endless web. The diagnostic device is adapted to monitor operation of the sorter apparatus and includes at least one sensor that is adapted to detect at least one parameter of a proximate drive that is proximate to the at least one sensor, and a controller adapted to receive the at least one parameter from the at least one sensor. A stationary thermal sensor may also monitor the endless loop via another controller including receiving thermal data from the stationary thermal sensor and the another controller correlates the thermal images with a portion of the endless loop.

International Classification:

F16M 13/02
B65G 43/00
B65G 41/00

Abstract:

A conveyor system, control assembly used with the conveyor system, and method of assembling a control assembly to a member made of ferromagnetic material. The control assembly has a control housing that houses at least one control component that is adapted to perform a control function. A support mechanism supports the control housing with the member. The support mechanism includes at least one permanent magnet mounted at a surface of the control housing that is adapted to attract the housing to the ferromagnetic material and a positioning feature. The positioning feature resists movement of the housing with respect to the member. The positioning feature may be adapted to resist movement of said housing with respect to the member in at least one degrees of freedom and perhaps in at least two degrees of freedom.

B65G 15/60
B65G 23/44

Abstract:

A belt conveyor having a pair of side frames between which a belt is moved for conveying items includes a pair of idler rollers about which the belt is disposed for conveying items there between, a tension roller that is biased into engagement with the belt, and a driven roller operative to drive the belt about the idler and tension rollers. The tension and driven rollers are mounted between the side frames and are disposed lower than the idler rollers, with the tension roller mounted by a tensioner mount configured to impart a biasing force to the tension roller against the belt.
