Abstract: Method and apparatus for filling bags with loose materials, wherein a package to be filled is filled by means of a filling element in a filling process. The filling process comprises a filling stage, a settling stage, and a discharge stage wherein during the filling stage, loose material is filled into the bag while admitting air and in the settling stage, a settling phase is provided for the pressure to drop and in the discharge stage, the bag is discharged from the filling element. In the settling phase, the squeezing device applies a squeezing pressure to the package so as to vent the package and to reduce the volume available to the package, until a predetermined reduction of the volume available to the package is reached, whereupon the squeezing pressure of the squeezing device on the package is reduced and the package is discharged from the filling element.

Abstract: In an inner structure of a filler neck of a fuel filler tube, a nozzle support section for supporting a nozzle of a fuel filling gun at a gas station includes a pipe member having an inner diameter substantially equal to the outer diameter of the nozzle, and the nozzle is inserted in the pipe member when fueling. Fuel emitted from the nozzle is directed through the pipe member to an outlet end (distal end) of the nozzle support section, at which it starts flowing along an intermediate bent section of the filler tube. Thus, even when the fuel filling gun is not sufficiently inserted in the filler neck, i.e. inserted short of a standard inserted amount, the fuel is allowed to properly jet out in the bent section just as when the fuel filling gun is sufficiently inserted in the filler neck up to the standard inserted amount.

Abstract: A device for blending materials and a bag for use in such devices. The device has at least one paddle for acting on a sample and a carrier against which a sample may be crushed by the paddle. The device is arranged to allow adjustment of the spacing between the paddle and carrier during operation. The bag is suitable for use in such a device but can be used in other devices.

Abstract: The invention relates to a metering installation for powder pigments, having an arrangement for supplying the powder pigments into a weighing container of a weighing arrangement. The weighing container may be emptied into a pneumatic conveying conduit which leads into a consuming unit, if appropriate, via an intermediate store. The conveying arrangement has a hopper-like pressure container which can be subjected to the action of compressed air. The pressure container has a closure at the base and a laterally curved outlet connector. An injector tube, which can be subjected to the action of compressed air and has lateral exit openings for the compressed air, extends axially into the outlet connector.

Abstract: The present invention is a system for filling a container main body at least whose drum body is made of a flexible film, with a viscous material. A viscous material is charged by the charging means into container main bodies conveyed by the container conveying means, the drum body of the container main body is pressed by the pressing means to cause the surface of the viscous material to bulge, and the opening of the reinforcing component of the container main body is capped by the capping means, allowing the opening to be capped in an air-tight manner with a lid member while virtually all of the air inside the container main body is evacuated, and preventing air from being left over in the container main body so as to prevent hardening, curing and deterioration in the quality of the viscous material that can be caused by such remaining air.

Abstract: An apparatus is provided for pre-conditioning the materials in a bulk bag to effect easier unloading of the materials. A frame is provided with an open space for receiving the bulk bag. A series of spaced-apart, opposing breaker bars is provided for automatic thrusting against the sides of the bags to break up compacted material. The bars preferably have an angled profile. Parallel pairs of opposing horizontal bars are provided, evenly spaced from the bottom; and preferably a single opposing vertical pair is provided on the opposite sides. The pairs of bars are operated, by thrusting into the sides of the bag, in a timed sequence, to effect break up of the material. Additionally, a series of bars may be provided on the bottom of the frame, such that a break up effect is achieved against the material residing in the bottom of the bag.

Abstract: A vertical auger bottom-fill bag filling machine including a conical auger bowl depending from a cylindrical hopper on rocker arms, with the auger bowl being connected to the cylindrical hopper and a fill tube by flexible gaskets. A vertical auger shaft extends through the cylindrical hopper, auger bowl, and fill tube, with a section of flighting disposed within the auger bowl and fill tube to compress, de-aerate, and dispense the product. An agitator is mounted on the bottom of an agitator drive shaft which circumscribes the auger shaft and rotates independent thereof, the agitator having paddles which move the product and press the product downwardly in the auger bowl. An inverted venting cone is disposed within the auger bowl, with a vent tube extending upwardly and terminating proximate to the top of the cylindrical hopper.

Abstract: A system for unloading powdered or granular materials from a container made of flexible material, the system including a line supplying compressed gas to the interior of the container to fluidize the material in the container, and a delivery conduit which may be attached to the container for delivering fluidized material from the container. A pair of arms are movable between a first position in which they are spaced from the container and a second position in which they engage and squeeze the container. Vibrators are provided for vibrating the container. The action of the arms and the vibrators facilitates unloading by breaking up clumps of the material in the container and preventing the formation of air pockets and material bridging.

Abstract: A compacting apparatus is provided for compressing material within a flexible bag including a pair of compression rollers which move from an upper to a lower position within the apparatus while contacting the bag. Vertically extending guide rails are provided for guiding the rollers in their movement and the rails are oriented in diverging relationship to each other to allow the rollers to move outwardly as they move downwardly. In addition, the guide rails are mounted to permit at least one of the rollers to pivot outwardly as the bag is filled with material and as the material is compacted.

Abstract: A vertical bottom-fill auger assembly including a bottom-fill auger bowl containing an internal rotating agitator or wiper element, and a vertical moving carriage or bag handling mechanism including a traveling bag settler. The vertical movement of the carriage or bag handling mechanism may be adjusted in response to the vertical auger revolution rate, the product density or weight as measured by a bulk or net weigh scale attached to the bag support assembly, or to comport to a premeasured charge that is bulk loaded into the auger bowl. The agitator or wiper may be of a configuration having a blade mounted on a rotating shaft vertically disposed in the center of the auger bowl, or may be carried on a rotating ring horizontally disposed at or near the top of the auger bowl. The traveling bag settler includes an arm which may be oscillated in a vertical plane to strike the bottom of a bag being filled, and which travels with the bag as it descends during filling and when lowered to a conveyor.
