摘要： A transfer conveyor for transferring products from the end of a first product conveyor onto a second product conveyor comprises transfer conveyor belts including movable flaps for lifting and carrying the product over a transfer gap between the first product conveyor and the second product conveyor. A frame guides the transfer conveyor belts and moves the flaps between a deployed and retracted position.

摘要： Conveyor belt modules having rodless hook hinges and modular conveyor belts constructed of those modules. Hooks on opposite ends of belt modules hook into complementary hooks on adjacent modules to interconnect the modules at hinge joints into an endless belt. The geometry of the modules enables them to be manufactured by extrusion.

摘要： A slat conveyor belt includes connected drive modules that can be easily disassembled and assembled. Each drive module comprises a slat portion connected to a drive portion forming a drive chain. A conveyor frame for the conveyor belt includes a dust cover for the drive chain and a separator for selectively separating a slat portion from an associated drive portion. A magazine automatically removes and stores separated slats.

摘要： A magnetic tray for a tray conveyor has a permanent-magnet array producing a magnetic field that interacts with an electromagnetic flux wave produced by a linear-motor stator to propel the tray in a conveying direction. The tray includes a top conveying platform supported on a mover housing the permanent-magnet array and a tray-clearing tool that removes conveyed articles or debris from the platform. The tray-clearing tool is powered by the stator.

摘要： A tray conveyor comprising ice-coated magnetic trays driven by a linear-motor stator along a rail track. The ice coating is applied to the trays to provide a product-bearing ice surface. After the product is processed and transferred off the tray, the top layer of the contaminated ice coating is removed and the tray with the remaining ice coating reused.

摘要： A conveyor-rail cleaner for cleansing, scrubbing, and rinsing the rails of a cleanable conveyor system. The cleaner includes cleaning units pivotably connected to allow it to negotiate turns in the track. Position-adjustable scrub brushes accommodate transitions between one-rail conveyor segments and two-rail segments at switch segments between separate adjacent conveyor tracks. The conveyor system includes a filling station for filling the cleaning units with cleansing and rinsing agents and recharging batteries powering scrub-brush motors.

摘要： A tray conveyor in which plastic trays with rows of embedded translators are driven by stators in multiple conveyor sections. Washing stations in cleaning zones in each conveyor section are provided to automatically clean empty trays in the conveyor's return path. Indicia on each tray identify the tray as belonging to a specific family of trays. Each of the conveyor sections conveys only conveyor trays that belong to a predetermined family assigned to that conveyor section.

摘要： A roller conveyor having a bed of rollers supported by air bearings and driven by a linear-motor stator. The rollers are made of electrically conductive or magnetic material to operate as rotors forming linear motors with the linear stator. Air bearings support the ends of the rollers. Intermediate air bearings support the middle of long rollers in wide conveyors.

摘要： A conveyor includes a powered pop-up roller driven by separable drive components. A first drive component is rigidly coupled to the frame of the conveyor. The first drive component induces motion driving the roller in a second drive component, which is fixed to the roller but separable from the first drive component.

摘要： 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.
