Abstract
The present invention relates to an apparatus for filling bags with a material and for sealing them, and it can carry the bags in a direction of a bag thickness. A first feature of the present invention resides in that, in the case that the bags are arranged between a pair of chain conveyors disposed in parallel vertical planes, they are gripped by plural pairs of grippers mounted on a pair of axes extending through each rectangular parallelepiped carrier. Further, a second feature of the present invention is that the apparatus according to the present invention is equipped with nozzles for introducing a compressed gas into the bags and pressure gauges for measuring a pressure within the bags in order to detect whether or not each bag is normally gripped by the grippers. Furthermore, another feature of the present invention is that a return pipe is fixed to a filling device so that the filling material may be returned to a storage tank, without being discharged therethrough, by closing the filling nozzle. Still another feature of the present invention is that seal bars for sealing the bags are covered with a heat-resistant cloth, and the cloth is sent out in turn to maintain uniform sealing conditions.
