Power-And-Free Conveyors

Power-And-Free Conveyors are variation of Overhead Conveyors .In a conventional overhead conveyor the carrier is permanently fastened to the drive chain. In the power and free case, the carrier can mechanically disengage from the drive chain and essentially idle while the chain continues to move. Power and free conveyors can also be inverted so that they can be mounted to the floor, in which case the carrier or tray rides on top of the guiding rail as opposed to being suspended beneath it.Power and free conveyors are ideally suited to demanding industrial environments that require a high degree of versatility.These systems provide the unique ability to stop individual loads without stopping the entire production line.It has played an important role in the improvement of productivity and quality in a wide variety of manufacturing environments.

Power-and-free conveyor is a conveyor that has inherent in its design.That is flexible routing, variable speeds, the ability to accumulate or stop carrier, sort product, and move through processes, overhead space utilization, precision to work with automation, and easily expandable and adaptable to product change.

A power and free conveyor wherein each load carrier comprises a plurality of trolleys, the foremost of which has dogs for engaging with driving dogs on the powered conveyor element. The rearmost trolley of each load carrier has control means operative when a following carrier comes into proximity with the rearmost trolley to disengage a driving dog of the following carrier from a driving dog of the powered conveyor element. The rearmost and next adjacent trolleys of each load carrier are connected with one another by a telescopic draft member which can pivot laterally relative to each trolley. The draft member contains a compression spring which absorbs a substantial part of the momentum of the following load carrier when the carriers come into proximity.
