Abstract: 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.

Abstract: 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.

Abstract: 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—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.
Abstract translation: 一种具有电磁驱动器的带式输送机，包括转子和密封在独立的非磁性和非导电壳体中的定子。 转子安装在驱动轴上。 支撑在轴上的驱动鼓或驱动链轮具有与输送带接合的外围驱动表面。 转子与外围驱动表面同轴，密封在滚筒或链轮内，或者容纳在与驱动表面轴向间隔开的轴上。 转子可以包括导电转子棒或永磁体。 定子与转子间隔开狭窄的间隙，并产生穿过间隙的行进磁通波，导致转子和外围驱动表面旋转并驱动传送带。

Abstract: 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.

Abstract: 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.

Abstract: 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.
