Abstract
Travelling carrier delivery equipment includes a delivery unit for transferring a travelling carrier that has no self-running means between a movable rail and a main rail by means of external friction-driven, and the travelling carrier is provided with a friction driving surface across its entire length, the delivery unit has a friction drive wheel and friction drive wheel moving means, the friction drive wheel is provided on the movable rail and is switchable between a driving state, in that it 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 (R), 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 (F), 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.
