Abstract

An apparatus for handling and conveying packages includes a conveyor frame for housing a combination roller-slider bed and a belt mounted on the combination roller-slider bed to define a package-supporting conveyor surface. The conveyor drive includes a drive pulley in contact with the belt, a gearbox coupled directly to the drive pulley and an electric motor coupled directly to the gearbox. The shaft of the drive pulley is designed to fit within the output shaft of the gearbox. The motor and gearbox are mounted adjacent to but outside of the conveyor frame. Electrical or mechanical system associated with the apparatus controls the speed and acceleration of the belt.

Claims

1. Apparatus for handling and conveying packages comprising:

a conveyor frame including roller and slider surfaces used in combination to define a conveyor bed;

said frame including a pair of opposed side frame members, each said side frame member including an upwardly facing slide surface;

a plurality of conveying rollers mounted between said side frame members, the upper most part of each said conveying roller being elevated with respect to said slide surfaces;

a plurality of return rollers mounted between said side frame members and below said conveying rollers;

an end pulley mounted between said side frame members at each end of said frame;

an endless belt positioned on said conveying rollers and extending over said slide surfaces to define a package supporting conveyor surface, said belt also mounted to contact said end pulleys and said return rollers;

a drive pulley mounted between said side frame members intermediate said end pulleys and below said return rollers and in contact with said belt, said drive pulley having an integral shaft with a driving key thereon, said integral shaft extending past one of said side frame members;

a shaft-mounted gearbox having a hollow output shaft with a keyway therein sized to receive said drive pulley shaft and driving key, said gearbox being mounted on and supported by said drive pulley shaft;

an electric motor coupled directly to said gearbox, said motor being supported by said drive pulley shaft; and

means for controlling the speed and acceleration of said motor.
