Abstract
Apparatus for variably accelerating a rotatable drive member comprises a slotted drive member mounted to rotate a drive shaft. A sun gear has two opposingly situated planet gears mounted to mesh with the sun gear. A driven annular gear rotates the planet gear. Each planet gear includes a cam member mounted to each planet gear off axis relative thereto. The cam members are received in the slotted drive member. As the annular gear is driven with angular velocity omega the cam members travel towards and away from the sun gear as they orbit around the sun gear. This movement causes the rotational movement applied to the drive member to vary between a maximum and a minimum angular velocity. Consequently, it is possible to arrange the apparatus to receive a rapidly moving product and slow it down before delivery onto a conveyor.
