A drive mechanism for a conveyor system. A pair of conveyors are located in parallel spaced relation and each conveyor includes a drive pulley with the drive pulleys being axially aligned. A transfer conveyor consisting of a plurality of parallel drive rollers is located between adjacent ends of the main conveyors. A rotatable input shaft driven by a motor is connected to a bevel gear unit which includes a pair of output shafts disposed normal to the input shaft and the output shafts are operably connected to the respective drive pulleys to drive the main conveyors. In addition, the bevel gear unit includes a second output shaft which is operably connected to one of the rollers of the transfer conveyor to drive that roller. Rotation of the driven roller is transmitted to the other rollers in the transfer conveyor by endless bands that are connected between adjacent rollers.
In a conveyor system, a first conveyor having a first drive member, a second conveyor disposed parallel to said first conveyor and having a second drive member axially aligned with said first drive member, a transfer conveyor disposed between adjacent ends of said first and second conveyors, a drive unit including a rotatable input member and a pair of axially aligned first output members disposed normal to said input member, said first output members being operably connected to the respective drive members to drive said first and second conveyors, said drive unit also including a second output member axially aligned with said input member and operably connected to said transfer conveyor to drive said transfer conveyor, said transfer conveyor comprising a series of parallel rollers, said second output member being operably connected to one of said rollers, and connecting means connecting said one roller to the other rollers of said series.
In a conveyor system, a first conveyor including a first endless belt and a first drive member to drive said first endless belt, a second conveyor disposed parallel to said first conveyor and including a second endless belt and a second drive member to drive said second endless belt, said first and second drive members being disposed in axial alignment, a drive unit including a rotatable input shaft, and a pair of axially aligned first output shafts disposed normal to said input shaft, bevel gear means interconnecting said input shaft with said first output shafts to drive said first output shafts in opposite directions, first connecting means for connecting each output shaft to the respective drive member, said drive unit also including a second output shaft operably connected to said input shaft, a transfer conveyor disposed between adjacent ends of said first and second conveyors and including a group of parallel rollers, said second output shaft being operably connected to one of said rollers of said group to drive said roller, connecting means connecting said one roller to other rollers of said group to drive said rollers, and guide means for guiding articles being conveyed on said first conveyor across said transfer conveyor to said second conveyor.
