Rexroth uses an inverted tooth drive chain as the centrepiece of a pick and place system that it has developed for a light bulb manufacturer. This robust, low-maintenance tooth chain allows implementation of extremely rapid cycles, enabling it to achieve the minimum cycle time of 1.2 seconds specified for the system. Running over four gear wheels, the chain drives two ball rail guides arranged at right angles. The guide rails in turn control a system that grips, moves and positions the light bulbs. The chain is composed of individual links that interlock gently in the gear wheel. Operation of this low-friction chain is extremely quiet.
