Abstract (en)
[origin: US4627781A] The invention relates to a bag-cutting- and emptying-device with a connected collective dust-removal filter, whereby it is the aim to replace the manual cutting process customary in devices of this type by a driven knife and to fix the position of the bag within the housing in such a manner so that this bag can be seized manually and can be shaken. Hereby, also in the case of an additional manual intervention, the bag-feeding-area is to be protected against infiltrating excess air through the intervention of appropriate means surrounding the bag. The invention makes provisions for the feeding of the bag through the intervention of a supporting-table (7/8) ending in a bag-chute (8), whereby the final boundary of the bag-chute (8) can be delimited by means of a stop-flap (15) for the support of the bag. In this position, the bag is cut in a curved manner by means of a knife (20) arranged at rocking-levers (19), with this being done in such a way so that the cut ends directly in front of the bag edge lying on top of the bag-chute (8). By means of the pressure cylinder (16) and theknife (20), the stop-flap (15) is driven in the direction of the end-position at each given time whereby, after execution of the cut, the stop-flap (15) is pivoted in downward position.
