Separate Weigh Chamber Patents (Class 177/55)
  • Patent number: 8866029
    Abstract: A link apparatus supplies objects discharged from a weighing machine to package bags being conveyed successively at a high speed and comprises plural hopper groups each including n hoppers; and plural arms configured to convey an associated hopper group along a revolving path including a first area where the objects are supplied to the hopper group and a second area under which package bags are conveyed successively. The arms convey the hopper groups from the first area to the second area in a predetermined order, the n hoppers sequentially conveyed to the second area are located above the n package bags conveyed to a region under the second area; the hoppers are located above the package bags in the second area, and the hopper groups are stopped in the first area. The hopper groups discharge the objects, when the hopper groups are conveyed in the second area.

  • Patent number: 7210570
    Abstract: The device for dynamically weighing postal items (P) comprises a plate (1) floatingly mounted on a weight sensor, and a conveyor belt mounted on the plate to move the postal items in a longitudinal direction (D) of the conveyor. The conveyor has two parallel conveyor belts (2C, 3C) which extend along the conveyor direction between a conveyor inlet (E) and a conveyor outlet (S), and between which the postal items are pinched and moved in series on edge. The two conveyors belts are engaged on a pair of first elastically deformable finned wheels (2A, 3A) disposed at the inlet (E) of the conveyor and being aligned perpendicularly to the longitudinal direction, and on a pair of second elastically deformable finned wheels (2B, 3B) disposed at the outlet (S) of the conveyor and being aligned perpendicularly to the longitudinal direction, and the operation of the weight sensor is based on the electromagnetic principle of flux compensation.

  • Patent number: 4972882
    Abstract: An automatic weight sorter used with a rotary container filling machine for sorting filled containers by weight. The filling machine has a rotary platform with a plurality of filling stations in which the containers, such as bottles, are supported for filling liquid product dispensed through a filling head at each filling station. The sorter is disposed at the exit end of the filling machine for successively weighing the filled bottles to sort them into predetermined classes of weight. The sorter is provided with an electronic device for storing measured weights for each filling station, calculating average weight for each station, counting the number of the sorted bottles in each class for each filling station, selectively displaying these data on a display screen and generating an alarm when the number of defective product exceeds a predetermined value.

  • Patent number: 4849175
    Abstract: A method and apparatus for automatically measuring the grain fineness, the gypsum content and the limestone content of a cement sample.A first fraction of the sample is loaded by a vibrating hopper into a crucible resting on an automatic scale. This crucible is handled sequentially by tongs on two revolving arms carried on slidable vertical shafts. The circular paths of the arms intersect at a point just above the scale. Motions of the arms and of the tongs are controlled by a programming unit. The weighed sample is poured into a sieve and the weight of oversize grains is automatically related to the sample weight.Gypsum is measured by heating a second fraction of the sample at 1000.degree. C. plus in an oxygen stream, Fe powder being added from a fixed hopper. The crucible is raised into an induction furnace. Released SO.sub.2 is bubbled in a titration cell to which potassium iodate is gradually added by a burette giving an automatic read-out of the SO.sub.3 (gypsum) titration.

  • Patent number: 4715412
    Abstract: Method and apparatus for check-weighing a product charge in a continuously operating conveyor system without interrupting the operation and without having extra empty containers in the system after a check-weigh has occurred. Containers are fed forward in a series to a filling station where they are filled with a measured charge of product. When a check-weigh is desired a container is prevented from entering the series, a gap occurs corresponding to the measured charge to be check-weighed, and that charge is diverted to a scale and weighed while subsequent containers receive their charges uninterrupedly.

  • Patent number: 4522788
    Abstract: The specification discloses a proximate analyzer for the analysis of fossil fuels such as coal and coke. The analyzer includes a temperature-controllable and atmosphere-controllable furnace chamber, a balance having a weigh platform positioned within the furnace chamber, and a platter positioned within the chamber and adapted to support a plurality of sample-containing crucibles. The furnace further includes means for continuously depositing the crucibles in a predetermined sequence on the weigh platform and means for monitoring the weights of the crucibles to determine when analysis is complete and for calculating the proximate analysis results based on weight loss. A method of proximate analysis using the proximate analyzer is also disclosed.

  • Patent number: 3995668
    Abstract: This invention relates to a new and useful apparatus that incorporates the precision and accuracy of net weight fillers with the speed and economy of volumetric fillers. The invention comprises means for receiving a flowable product, said means being connected to a scale. When the product within the receiving means reaches a predetermined weight, it is deposited into a cavity having a plurality of equal chambers and is evenly distributed therein by rotary motion means. A plurality of containers are positioned relative to the cavity to receive the product from the chambers.
