Abstract: A portable material delivery apparatus for transporting and depositing a flowable material at a deposit site, including a vehicle and a hopper mounted on the vehicle for holding the material and having a lower opening for releasing the material. First and second circulating conveyors move the material released from the hopper to the deposit site. The first conveyor is fixed beneath the hopper. The second conveyor is vertically tiltable and laterally rotatable relative to the first conveyor. The apparatus includes a control station with an operator platform and controls for controlling the conveyors. The control station is mounted to and is movable with the second conveyor as it tilts and rotates. The control station is positioned such that a single operator standing on the operator platform can operate the controls while directly observing the material moving on the second conveyor and being ejected toward the deposit site.

Abstract: A combinational weighing machine has not only a plurality of weighing devices for weighing articles and outputting signals indicative of their weight values and a control system for calculating combinations of the weight values, selecting a combination of weighing devices according to a given criterion and causing articles to be discharged from the selected combination of weighing devices, but also a discharge chute for receiving the discharged articles and leading them to a discharge opening and a guide member disposed inside the discharge chute with a sloped outer surface serving to deflect the articles colliding therewith into a vertically downward direction.

Abstract: In a gravimetric weighing hopper, an infeed chute on the fixed hopper frame and a removable annular wall supported by a load cell are formed with respective annular edges which are angled relative to their aligned axes or are correspondingly notched or otherwise have annular portions about at least approximately one-half of their respective annular extents which are spaced axially from their remaining annular extents to enable the removable cylindrical wall to be spaced in close surrounding relation to the feed chute during normal operation and also to be readily manipulated relative to the feed chute when necessary or desired to be removed from the hopper.

Abstract: The new invention is directed to a continuous mixing and homogenizing plant, particularly for mill products. In so doing, the simultaneity of the mixing of all raw components in a pre-mixing space 8 is ensured in particular, so that subsequent continuous homogenization is also possible so as to meet the strictest demands. The utilized component weigher 4 and the assigned screw discharge 25 are constructed so as to be substantially tubular and together form a differential flow regulator 6. The inner surface of the entire system contacted by the product is accordingly tubular and is subjected to a continuous self-cleaning as a result of the movement of the product. Further, it is possible to arrange a plurality of component weighers 4 in a geometrically identical manner with respect to a collecting point 17 and a very high quality of mixing is obtained.

Abstract: A bag filling apparatus includes a hopper for receiving raw material. The hopper feeds the material through an opening to a conveyor belt for transporting the material to a bagging head. The bagging head includes a gate having two positions for selectively diverting the material to one of a first and a second outlet ports. Underneath the bagging head is a receiving scale having a first pan and a second pan, each adapted to hold a bag for receiving the material, and a movable counterweight. The scale is constructed to move between two positions: a first position wherein the first pan is adjacent the first outlet port and the counterweight is adjacent the second pan and a second position wherein the second pan is adjacent the second outlet port and the counterweight is adjacent the first pan. The movement of receiving scale between the two positions occurs automatically when the sandbag reaches a preselected weight.

Abstract: Apparatus for filling containers alternately with predetermined quantities of material has two container positions to be fed alternately and a material guide arrangement with alternative outlets that supply the material to containers at these two positions. A pair of container support frames are arranged side by side on the front pair of a main frame, and these support frames are mounted by pivot arms to the main frame in a parallelogram arrangement. Rearwardly of the main frame front part are counterweights or counterbalances supported on either upper or lower ones of the pivot arms. An upper part of each of the support frames has a mechanism that coacts with a cooperating mechanism on the material guide arrangement to change the position of a diverter plate when the container that is being filled overbalances the corresponding counterbalance and causes the associated support frame to descend.

Abstract: A combinatorial weighing apparatus for weighing out articles includes a base having a top surface which is quadrangular in shape, and a plurality of weighing hoppers mounted on the base, side by side, horizontally along a substantially straight line. Mounted on the base are weighing mechanisms for measuring the weights of articles introduced in corresponding weighing hoppers, and a hopper drive mechanism for obtaining a combination of the articles giving a total weight closest to a target weight and for actuating prescribed ones of the weighing hoppers. A chute for receiving articles discharged from each of the weighing hoppers, and a collecting hopper for collecting the articles from the chute are also mounted on the base. The weighing hoppers, chute and collecting hopper are disposed on the front side of the base. The combinatorial weighing apparatus is ideal for use in combination with others of the same construction.
