  • Patent number: 9221560
    Abstract: A vibrating device for uniformly filling granular ornaments includes a base, a vibration platform, a motor, a first vibrating assembly for generating vibration in an up-down direction, and a second vibrating assembly for generating vibration in a left-right direction. The vibration platform is articulated at the base and provided with multiple through-holes for holding workpieces, such as pen caps. The motor is fixedly mounted at the base. The first vibrating assembly and the second vibrating assembly both are provided between the motor and the vibration platform. The motor drives the first vibrating assembly to make the vibration platform vibrate in the up-down direction, and at the same time drives the second vibrating assembly to make the vibration platform vibrate in the left-right direction. Thus, granular ornaments can fill the cavities of pen caps located within the through holes in the vibration platform.

  • Patent number: 5315810
    Abstract: A method is provided for filling seed trays particularly tobacco seed trays, with growing filler material whereby dry pockets are prevented from forming in the seed trays. The method includes partially filling an upright loading device with the filler material in a manner so that the surface plane of the filler material is at an inclined angle of repose with respect to horizontal. A leading edge of the filler material is established and maintained from the front end of the loading device. A seed tray is passed below the loading device so that the forward edge of the seed tray initially passes below the leading edge of the filler material so that the filler material cascades down into the individual pockets of the seed tray at a controlled rate. In practicing this method, the individual pockets of the seed tray are generally completely filled from the bottom up with the filler material before being conveyed under the bulk portion of the filler material, thereby minimizing the occurrence of dry pockets.

    Abstract: A hopper-feeder system for feeding stored powders at a uniform, controllable and predetermined rate. A spiral convoluted stirring agitator in close proximity and conforming to the hopper wall is rotated in a direction tending to lift and dilate the powder, counteracting its tendency to bridge and to undergo intermittent or non-uniform changes in density and rate of discharge. The head load upon the feeder as well as the material damping effect on the feeder are controlled by a column cutter on the agitator that undercuts the column of powder extending through the hopper opening.

  • Patent number: 4597420
    Abstract: A multipoint dispensing of viscous material onto a board (23) comprises the monitoring and controlling of several process parameters such as the initial gap (.delta.) between a dispensing tool (20,25) and the board (23), the dispense pressure time cycle within the tool (FIG. 3A) and the tool velocity cycle (FIG. 3B). Also, an improved method for loading solder paste into the dispensing tool includes applying vacuum to two regions of the tool while vibrating it in its axial direction (FIG. 4). Furthermore, improved techniques for preventing crust formation on the paste within the tool, and for controlling the viscosity of the solder paste within the tool, achieve consistent dispensing results in a production environment.

  • Patent number: 4556090
    Abstract: A vacuum fluidized powder feed apparatus for filling an evacuated mold. The fluidized powder feed apparatus has a feed cup defining a cylindrical cavity for holding a quantity of powdered material and a powder exit aperture provided through the bottom of the feed cup mating with the fill aperture of the mold. A porous annulus disposed at the bottom of the cylindrical cavity has a conically shaped internal surface sloping toward and mating with the exit aperture of the feed cup. Vent holes provided in the side walls of the feed cup cause a fluid flow through the porous annulus into the interior of the cylindrical cavity which is connected to the evacuated mold cavity through the exit aperture. A pneumatic piston received in the cylindrical cavity engages the top of the powdered material and produces a force cavity urging the powdered material towards the exit aperture.

  • Patent number: 4549584
    Abstract: A process and apparatus for filling and packing a chromatographic column by the wet route in which a compression chamber is attached to one end of the column having an internal bore equal to the internal diameter of the column and aligned therewith to form a combined chamber, a fluid suspension of packing particles is introduced into the combined chamber and then a piston member is axially displaced within the compression chamber toward the chromatographic column to compact the packing particles in the column. The suspension liquid flows out of the column through a conduit formed through the piston and/or through the cap at the other end of the column. After compression, the compression chamber and piston are separated from the column and the packed column may then be attached to a chromatograph for use. Vibrators may be provided on the column or compression chamber to promote transverse rearrangement of the particles during compression.

  • Patent number: 4193430
    Abstract: A system for filling generally cylindrical barbell weight shells with a relatively viscous slurry of cementitious material comprises a roller conveyor which transports a plurality of carriers each supporting a plurality of barbell weight shells thereon through a plurality of stations. At a lubricating station, the exterior of the shells is coated with a light film of oil to facilitate subsequent cleaning thereof. At a filling station, a dispensing hopper having a plurality of downwardly projecting nozzles dispenses the cementitious slurry into the shells. Each of the carriers is positioned beneath the hopper, the shells thereon are aligned with the nozzles, and a lift table lifts the shells off of the roller conveyor into engagement with the nozzles. Vibratory and agitator devices induce the flow of the slurry from the hopper into the shells under the influence of gravity.

  • Patent number: 4142560
    Abstract: The disclosure relates to a machine which is adapted to fill a line of containers passing through a filling zone. The machine includes apparatus for delivering material to the containers which is arranged compactly yet is easily accessible for maintenance and cleaning. The material delivery apparatus includes a hopper located at the outlet end of the machine and an inclined endless belt conveyor extending upwardly from the hopper to a discharge location laterally spaced from and above the line of containers to be filled. The conveyor belt has flights which pick up portions of material from the hopper and deliver the portions to a shaker tray mounted for reciprocation offset and parallel to the line of containers. The shaker tray has a diagonal discharge edge for uniformly distributing an elongated flow of the material to a lower shaker tray mounted for reciprocation transversely to the line of containers.
