A motor driven roller support assembly includes a motorized roller having a cylindrical outer surface that is configured to rotate, a support frame within which the roller is mounted, and a roller support connected to the support frame and engaging the outer surface of the motorized roller. The roller support may include a pair of support wheels for contacting the outer surface of the motorized roller, and include a pivot whereby the roller support is moveable relative to the support frame. The assembly may be integrated with a transfer conveyor, such as a right angle transfer having transfer blades that include belts driven by the motorized roller. The roller support engages the motorized roller in a direction that is generally opposite from the direction in which the belts engage the motorized roller to thereby counteract forces imparted by the belts on the motorized roller.

A battery transfer device having a base, a plurality of multidirectional rollers coupled to the base, and a winch coupled to the base. Each of the rollers is configured to rotate about at least a first axis and a second axis that is positioned at an angle with respect to the first axis. The winch has a cable or rope configured for coupling to a battery, and the winch is operable to pull the battery across the rollers. Guides may be removably coupled to the base adjacent one or both sides of the base. A method of using the battery transfer device to remove a battery from a battery rack or install a battery in a battery rack.

A continuous mining machine trailing conveyor system providing a sandwich belt system that incorporates a set of hugging modalities to ensure that the sandwich belt system provides sufficient friction.

The disclosure provides a roller conveying device, comprising: a base, a plurality of electric rollers, a left blanking plate and a right blanking plate. the two ends of the left blanking plate and the right blanking plate are provided with a block respectively; the left and right sides of the block are accommodated in the through grooves of the left blanking plate and the right blanking plate respectively; the left and right sides of the block are provided with a recessed cavity respectively; the two ends of the left blanking plate and the right blanking plate are provided with a baffle plate respectively, and the baffle plates of the left blanking plate and the right blanking plate are respectively accommodated in the recessed cavities on the left and right sides of the block to limit the movement of the block, thereby limiting the movement of the base.

A roller system has a frame, a plurality of rollers (supported by the frame) forming a roller plane, and an external rotor motor (“motor”) spaced from the roller plane. As an external rotor motor, the motor has a stator and an external rotor radially outward of the stator to substantially circumscribe the stator. To kinetically couple the motor with the rollers, the system also has a transmission coupling coupled with the external rotor and at least one of the rollers. The transmission coupling and external rotor are configured so that rotation of the external rotor causes the at least one roller to rotate in response to a torque received through the transmission coupling.

Various embodiments are directed to predicting and mapping a location of an object transported by a conveyor system with respect to a sequence of zones of the conveyor system. An example method includes detecting the presence of the object in a first zone using a first photo-eye. The first zone is controlled with a first roller rotational speed. The method further includes generating a virtual map to describe a location of the object. The location of the object is dynamically determined at least by predicting the object's presence in a given zone using a roller rotational speed of one or more preceding zones and configuring a roller rotational speed of the given zone in accordance with the object predicted to be present in the given zone. The method further includes evaluating the virtual map's accuracy with detecting the object in a final zone using a second photo-eye.

A belt conveyor includes a conveyor belt configured to move in a longitudinal direction. The conveyor belt has two large faces, and a number of support stations distributed longitudinally along the conveyor belt. The support stations are configured to support the conveyor belt by one of the large faces. At least one support station includes a drive motor configured to drive the conveyor belt in the longitudinal direction relative to the support stations.
