ABSTRACT:
An automatic bagging machine includes a bag-pickup station, a bag-filling station and a bag-tying station spaced equidistant from one another circumferentially around an orbit. A vertical shaft positioned centrally of such stations supports a set of radially extending bag-holding and spreading arms over each of the stations. Drive mechanism incrementally rotates the central shaft to move each set of arms sequentially from the pickup station to the filling station, then to the tying station and back to the pickup station. Control mechanism actuates the arms to pick up and spread a bag at the pickup station, grip and maintain the bag open for filling at the filling station, close the filled bag for tying at the tying station, release the filled and tied bag over a discharge conveyor and move the arms into position for picking up another bag at the pickup station. The drive mechanism also reciprocates a lower arm between the filling and tying stations for steadying each filled bag while it is being moved between such two stations. Brake mechanism is provided to decelerate the holding and spreading arms as they approach a bagging machine station.
