ABSTRACT:
A torque motor is directly coupled to a starwheel in a system for conveying containers. The torque motor has the unique characteristics of generating a constant torque while operating at the speeds of the starwheel between standstill and the maximum speed at which the containers are conveyed on the conveyor line. The torque motor normally produces a sufficient torque in a direction to overcome the running friction of the starwheel system, thereby causing the starwheel to be effectively a frictionless freewheeling device under all operating conditions.
A detector is disposed at a position along the conveyor line in front of the starwheel. The torque from the motor is reversed to produce a braking action on the starwheel when the detector indicates an interruption in the conveyance of the containers. The braking of the starwheel to a standstill is timed so that a particular number of containers (the prime) remain between the detector and the starwheel.
When the conveyance of containers is initiated again, the torque motor is energized for a particular period of time to produce a torque greater than that normally provided to overcome the running friction of the starwheel. This causes the containers in the prime to be accelerated so that a graceful melding is produced between these containers and the containers on the other side of the detector.
The combined advantages of the torque motor drive and associated controls are a minimizing of container impact in the conveyor line, prevention of container jamming at infeed of the starwheel system and a condition of smoother and unimpeded flow of containers in the line.
