Patent ID: 7721871

Claim:
Travelling carrier delivery equipment comprising a main rail, a movable rail which can be connected to the main rail by moving, and a delivery unit for transferring a travelling carrier between the movable rail and the main rail, wherein a friction driving surface parallel to the moving direction of the travelling carrier is provided across the entire length of the travelling carrier, the delivery unit has a friction drive wheel and friction drive wheel moving means, and the friction drive wheel is provided on the movable rail and is switchable between a driving state in that the friction drive wheel propels the travelling carrier via the friction driving surface and a driving release state, and the friction drive wheel moving means reciprocates the friction drive wheel between a retreating position at which the friction drive wheel can be made to contact with the friction driving surface of the travelling carrier supported on the movable rail and a forwarding position at which the friction drive wheel can be made to contact with the friction driving surface of the travelling carrier supported on the main rail.
