A transfer system comprising a carrier attached by fastening structure to a linear-motor shuttle driven by a linear-motor stator along a track. Tray packs or other conveyed objects are transferred between the carriers and infeed and outfeed conveyors by the carriers at transfer segments as the carriers advance along the track.

Conveyor transfer system

A hygienic magnetic tray and conveyor. The low-profile tray includes a forcer sandwiched between an article-supporting top and an opposite bottom. The top is made of hygienic material, and the bottom can be made of a low-friction material. The tray is propelled along a guide surface on an enclosure housing stator coils supported in a conveyor frame. The stator forms a linear motor with the forcer in the tray. Roller balls protruding from the bottom of one version of the tray provide low-friction rolling contact with the guide surface. Various disposal systems provide escape routes for removing fluids and debris from the guide surface of the stator enclosure.

Hygienic low-friction magnetic tray and conveyor

Components of a conveyor system designed to facilitate tight transfer of products onto and off a positively-driven, low tension conveyor belt. The conveyor system includes a tension amplifier in a returnway of a conveyor belt circuit for selectively increasing tension in the conveyor belt prior to infeed without increasing the low tension in the returnway prior to the tension amplifier.

Positively-driven, low tension transfer conveyor

A belt conveyor having an electromagnetic drive comprising a rotor and a stator sealed in separate nonmagnetic and nonconductive housings. The rotor is mounted to a drive shaft. A drive drum or drive sprockets supported on the shaft have peripheral drive surfaces that engage a conveyor belt. The rotor is coaxial with the peripheral drive surface&#x2014;either sealed within the drum or sprockets or housed on the shaft axially spaced from the drive surface. The rotor may include conductive rotor bars or permanent magnets. The stator is spaced apart from the rotor across a narrow gap and produces a traveling magnetic flux wave across the gap that causes the rotor and the peripheral drive surface to rotate and drive the conveyor belt.

Belt conveyor and electromagnetic drive

A cleanable belt conveyor and a method for making a cleanable belt conveyor having an underside sculpted with concave indentations to match the shape and positions of the elongated support rails forming a carryway. The support rails may be circular in cross section, and the indentations may be complementary portions of circular cylinders to receive the rails along an extended contact area.

Cleanable conveyor belt and carryway

A conveyor comprising a conveyor belt having rollers with metallic or magnetic rotors. A magnet or metallic element next to the conveyor belt is positioned to rotate the rotor. A magnetic field produced by the magnet or by the magnetic rotor rotates the rollers as they pass the magnetic field or as the magnetic field is changed.

Conveyor belt apparatus including magnetically actuated rollers

A modular conveyor belt and method provides a conveyor belt having rollers with metallic or magnetic rotors. A magnet or metallic element next to the conveyor belt is positioned to rotate the rotor. A magnetic field produced by the magnet or by the magnetic rotor rotates the rollers as they pass the magnetic field or as the magnetic field is changed. In one embodiment, the magnetic field is in the form of one or more switched reluctance motors.
