A transfer device including a main conveyor part having a first conveying surface and a subsidiary conveyor part having a second conveying surface and arranged at the same area as the main conveyor part, the main conveyor part being designed to convey an article placed on the first conveying surface in one conveying direction, the subsidiary conveyor part being designed to convey an article placed on the second conveying surface in another direction transverse to the conveying direction of the main conveyor part, the main conveyor part and/or the subsidiary conveyor part being a roller conveyor having rollers, at least one of the rollers being a braking roller equipped with a brake, and the brake being designed to prevent the article from proceeding at least to the direction transverse to the conveying direction of the roller conveyor by a frictional force acting between the article and the braking roller.

Transfer device

A motorized roller includes a roller body of a cylindrical shape, in which a motor and a reducer are housed. The motorized roller has fixed shafts protruding out of both ends of the roller body. A first fixed shaft has a cavity, in which a first connector is housed. A second connector is connected to the first connector. The first fixed shaft has a first engaging part (inside screw) for preventing disengagement of the second connector, so that a part (screw forming part) of the second connector is engaged with the first engaging part.

Motorized roller and motor unit for motorized roller

A conveying apparatusincludes a main conveyor lineformed by a motorized rollerand a free rollerarranged at specified intervals and a diverting linefor diverting an article from the main conveyor line. The diverting linehas a diverting unitwith a pair of a diverterintegrated on a frame A driving devicefor operating the diverteris arranged with casingsprovided at both sides of a main roller. The main rolleraccommodates a motorand first planetary gear mechanismsin a hollow cylinder. The casingseach accommodate a second planetary gear mechanismin a cylindrical casing. The first planetary gear mechanismeach form a planetary type on the condition that an eccentric memberis rotatable, and form a star type on the condition that the eccentric memberis unrotatable, thereby switching lifting operation of the diverterand transverse conveying operation of an article by means of belts

Driving device and diverter, diverting unit, and conveying apparatus incorporating the driving device

By housing a driver circuit board in a motorized roller having a built-in electric motor, the troublesome external wiring can be dispensed with, thereby facilitating the mounting of the roller on other apparatus. The heat generating inside the roller from a driver circuit board in the roller is dissipated by a heat releaser, thus protecting the devices from damage and avoiding failure of control.
