Abstract: A spiral conveyor for positively driving a conveyor belt along a helical path. The spiral conveyor includes a rotating cylindrical tower with parallel drive members extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge that varies in height from the bottom to the top of the tower. The variations in height facilitate the belt's entry onto and exit from the tower and robust, positive driving engagement with the inside edge of the belt along the majority of its path along the tower.

Abstract: A radius conveyor comprising a sideflexing conveyor belt and a touchless magnetic bearing at the inside of a turn. The conveyor belt has electrically conductive elements in a side edge. An array of permanent magnets along the conveyor's side rail at the inside of the turn produces a permanent magnetic field. As the conveyor belt is driven through the turn, the permanent magnet field induces currents in the electrically conductive material. The currents produce reaction magnetic fields opposed to the permanent magnetic field that result in a radially outward force pushing the conveyor belt away from frictional contact with the side rail. Alternatively, permanent magnets in the side edge of the belt and electrically conductive elements in the conveyor's side rail likewise provide a magnetic bearing.

Abstract: A cleanable belt conveyor having a locking mechanism. A locking mechanism including two locking protrusions is used to lock a first conveyor component to a second conveyor component. The locking mechanism comprises a base plate having at least one opening for receiving a locking protrusion and at least one handle plate including the locking protrusion. A saddle extending from one side of the base plate cradles the locking protrusion and may engage a pivot post of a conveyor component.

Abstract: A drive system for a motorized roller that includes a secondary stator external to the motorized roller. The outer shell of the motorized roller contains electrically conductive or magnetic material to form an induction, permanent-magnet, or reluctance motor with the secondary stator and boosts or bucks the torque of the motorized roller.

Abstract: A modular spiral belt constructed of a series of hingedly interconnected belt modules arranged in a helical stack. The modular spiral belt includes outer side plates, inner side plates and intermediate attachment members. The intermediate attachment members provide support for the conveyor belt to prevent sagging in an intermediate region.

Abstract: A magnetic conveyor belt module integrates a magnetic element into the body of the module to attract conveyed articles to the body. A magnet seat below the top surface of the body seats the magnetic element, so that the magnetic element is between the top surface and bottom surface of the module body. A retainer engages the magnet seat to retain the magnetic element in the seat.

Abstract: An article induction system for preparing a stream of articles, such as mail parcels, for processing employs a series of conveyors operating under control of a controller for feeding articles to an operator at a cull belt at an optimal paced rate. The article induction system includes a destacking section, a separation and alignment section, a buffer section and a culling section manned by an operator. A controller controls the speed of each component based on measurements provided by sensors so as to feed articles to the operator at a desired paced rate.

Abstract: An activated roller transfer apparatus for transferring articles between one conveyor and another. The roller transfer apparatus comprises a linear-induction-motor stator as a primary and electrically conductive article-supporting rollers as a secondary. The linear-motor stator generates a traveling magnetic flux wave that induces eddy currents in the rollers. The eddy currents produce magnetic fields that interact with the flux wave to produce forces that rotate the rollers to propel articles across a gap between the ends of the two conveyors. The stator is generally trapezoidal in shape to comport with the shape of the gap.
