  • Patent number: 6810921
    Abstract: A method of filling containers, especially bags, with bulk material by a feeding funnel and a filler pipe. The filler pipe adjoins the lower end of the feeding funnel. An axially displaceable and rotatable conveying unit is arranged co-axially within the filler pipe. An axially displaceable and rotatable closing element is firmly connected to the lower end of the conveying unit. The bulk material, while being conveyed by the conveying unit in the filler pipe, is simultaneously mechanically agitated in the filling funnel, or simultaneously mechanically conveyed in the filling funnel towards the filler pipe.

  • Patent number: 6786367
    Abstract: The present invention provides a filling sleeve which allows containers with a rectangular or square cross-section, especially bags with deep side folds, to be filled advantageously in that they are given a stable shape. The objective is achieved by means of a filling sleeve which is characterized in that, in the exit cross-section, a central region is provided with inserts and four separate exit apertures are kept open in the corners of the square or rectangular cross-section. In this way, the filling material flowing through the substantially completely open and normally undivided entrance cross-section of the filling sleeve is divided into four individual streams which are associated with the corners of the exit cross-section. Thus, while being filled, the bags are initially stabilized from the corners, as a result of which a certain tension remains in the walls between the corners, so that the walls cannot bulge out when the level of the filling material rises.

  • Patent number: 6237815
    Abstract: A dispensing device for pourable, especially powdery material, has a charging chute, a vertical filling pipe adjoining the lower end of the charging chute, and a closing cone arranged at the lower end of the filling pipe. The closing cone is displaceable in the longitudinal direction of the filling pipe by a shaft. The closing cone, in its open position, provides an annular gap at the lower end of the filling pipe. In its closed position, the closing cone rests against an annular face or annular edge at the lower end of the filling pipe. The closing cone, on an upwardly pointing conical face, includes blades with a desired slope. The closing cone is rotatingly drivable to convey material through the annular gap by the blades.

  • Patent number: 5878553
    Abstract: A process and device move at least one filled sack from a suspended position at an individual filling nozzle into an upright position on a moving conveyor belt for introduction into a sack closure device, where the travel speed of the conveyor belt corresponds to the closure speed of the sack closure device, in which the at least one sack is initially transported horizontally out of an area beneath the filling nozzle before it is then deposited on the conveyor belt, and the horizontal conveying speed of the sack is greater than the travel speed of the conveyor belt.

  • Patent number: 5305579
    Abstract: The invention relates to a device and method for expanding bags and slipping them on to a filling neck, especially bags with side folds, which are fed individually on to an aligning table, with the bag opening being positioned at the front, there being provided at least first suction means which are supported at the aligning table and which, in the region of the bag opening, are movable against the lower bag wall; at least second suction means which are supported at the aligning table and which are movable against the upper bag wall, the two sets of suction means being removable from one another while being vacuum-loaded; a pair of expanding blades which are movable into the seams of the side folds, which are secured to first pivot elements and are pivotable around a horizontal pivot axis positioned above the aligning table; a pair of bag grips with pairs of claws which are pivotable around rotational axes positioned parallel to the plane of the aligning table and, in consequence, may be opened and closed and

  • Patent number: 5301492
    Abstract: A bag clamping device for holding a bag to be filled, especially a bag with side folds, on a filling neck, the bag clamping device being formed by: a first pair of clamps, each comprising clamping members for holding opposed first bag wall segments on the filling neck, and a second pair of clamps each comprising pairs of clamping members, the pair of second clamping members comprising first surface parts which, in pairs, rest against one another in such a way that any bag wall parts positioned in front of the end faces are gripped and held in the bag edge region, as well as second surface parts which are arranged at an angle relative to the first surface parts which are adapted to the end faces and guiding plates of the swung-out expanding flaps for the purpose of holding the remaining free bag wall parts tightly around the filling neck.
