Abstract
A conveyor belt transporting apparatus for conveying carriers includes at least one conveyor belt frictionally engaged with the carrier, the conveyor belt formed of two belt layers, one lying on top of the other and extending between pulleys. A friction finger on the carrier is in frictional engagement with the belt by extending between its layers in frictional contact with both layers. Frictional contact force between the belt layers and the friction finger is variable by a moveable tension finger controllable by an automatic release element in response to blockage of movement of the carrier along the conveyor system. When the motion of a carrier is blocked by a stopped carrier or other impediment ahead of it, the release element is moved to release the friction force on the carrier finger engaging the belt. Verticle and horizontal guide and support rollers guide the carrier and support its weight.
