The invention relates to a method for assembling a roller conveyor having rollers for products, each having a cylindrical roller body and a first and second support element on opposite ends of the roller body, the second support element having pulley means; providing a frame having a first and second frame part for mounting therebetween the rollers; and, for the purpose of mounting a roller to the frame: mounting the first support element to a first mounting provision of the first frame part; passing a drive element and a further drive element over the pulley means of the roller; tensioning the drive element by exerting a force on the roller by means of a tensioning device; mounting the second support element of the roller to a second mounting provision of the second frame part while keeping the drive element tensioned; and removing the tensioning device from the roller.

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 singulating conveyor having a herringbone pattern includes transporting rollers extending from the entry end to the exit end. The rollers are divided into four longitudinal zones, and each longitudinal zone is divided into a pair of side-by-side complementary outside and inside lateral zones. The rollers of each of the eight lateral zones are driven by a separate motor and V-Belt drive system that can be operated at differing speeds. The speed of the transporting rollers in the four longitudinal zones increases successively from the longitudinal zone adjacent the conveyor entry end towards the longitudinal zone having the discharge rollers, and the speed of the rollers of the outside lateral zones operate at higher speeds than the rollers of the adjacent inside lateral zones. Some of the rollers in the outside lateral zones preferably have higher coefficients of friction than the rollers of adjacent inside lateral zones.

A motorized conveyor system comprising: (a) one or more electrical motors that create movement in the conveyor system; (b) one or more rechargeable batteries that power the one or more electrical motors in the conveyor system; (c) one or more rollers that are driven by the one or more electrical motors; (d) two frames holding the one or more rollers driven by the one or more electrical motors; (e) one or more motor control electronic circuitry elements connected to the one or more rechargeable batteries; and (f) charging system circuitry connected to the one or more rechargeable batteries.

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.

A roller conveyor device including a three-line conveyor for conveying objects that form at least three lines extending in a conveying direction. The three-line conveyor includes first conveyor rollers for conveying ones of the objects that form at least one central line of the at least three lines, second conveyor rollers for conveying ones of the objects that form at least one non-central line of the at least three lines, and third conveyor rollers for conveying ones of the objects that form another at least one non-central line of the at least three lines. A rotary shaft of each of the first, second and third conveyor rollers includes a shaft end portion having a projection portion that projects out from a conveying path in a widthwise direction of the conveying path, and the projection portion is to be driven so as to convey the objects in the conveying direction.
