Abstract
Apparatus for cutting of bags containing tricklable materials, as well as for separating the goods from bag parts, with a sieve drum and separate outlets for the bag parts, oversized particles, and the goods to be discharged, comprising a bag guidance with a floor inclined in dependence of the load, in a quasi-uniform, upper-and-lower engagement of the cutters to the bag, the cutters being coaxially and peripherally aligned with respect to one another, as well as for a uniform fragmentation and distribution of the goods to be discharged over the length of the sieve drum through accumulation rings.
Claims21
An apparatus for cutting bags into bag parts, wherein each bag contains powdery to granular goods, and/or granular to flocculent goods, as well as for loosening, fragmentation and separation of the goods from the bag, or from parts of the bag, and wherein each bag is made of paper, synthetic material, jute or the like,
- comprising in combination,
- a receiving housing,
- a cutting mechanism disposed in said receiving housing,
- a conveyor arranged to feed said cutting mechanism,
- a drum housing communicating with said receiving housing, and having separate outlets for the bag parts, and for the goods to be discharged, respectively,
- a sieve drum disposed in said drum housing, and having a predetermined length,
- a directional chute having an inlet, being disposed in said receiving housing, and being provided with a floor,
- said cutting mechanism including a plurality of cutters disposed partly above said floor and partly therebelow, said cutters having an inlet region, said directional chute having through-going openings for said cutters,
- an axle secured to said chute near said inlet, said floor being disposed pivotably about said axle, said axle being inclined along the direction of said inlet region in dependence on a load acting thereon,
- at least one resilient element supported at least indirectly on said receiving housing so that the inclination of said floor for a practically equal penetration depth of said cutters into the bag is set independently of the weight and thickness of the bag,
- said cutters being arranged in pairs so that the cutters of each pair face one another, a first cutter of the pair being coaxially aligned with the first cutters of all remaining pairs, the second cutter of the pair being coaxially aligned with the second cutters of all remaining pairs,
- at least one accumulation ring extending in a discharge direction, starting from a supply side of said goods, at least over a partial region of the length of said sieve drum.
