Definitions

  • ABSTRACT An apparatus for filing a receptacle with compacted pulverulent material comprising a compaction compartment equipped with a closable inlet and outlet.
  • a negative pressure source, atmospheric pressure and/or an overpressure source can be connected via a filter mechanism with the compaction compartment.
  • a supply compartment is connected following the compaction compartment, the outlet of the supply compartment being equipped with a dosing mechanism.
  • the present invention relates to a new and improved construction of apparatus for filling a receptacle or any other suitable material receiving device, simply generally referred to herein as a receptacle or container, with compacted pulverulent material, and which apparatus is of the type comprising a compaction compartment equipped with a closable inlet and outlet, and wherein a negative pressure source, atmospheric pressure and- /or an overpressure source can be connected via a filter mechanism with such compaction compartment.
  • an apparatus for filling a receptacle with compacted pulverulent material is known to the state-of-the-art wherein there is likewise provided a compaction compartment equipped with a closable inlet and outlet.
  • This compaction compartment can be connected through the agency of a filter device with a negative pressure source, atmospheric pressure and/or an overpressure source.
  • At the lower end of the compaction compartment there is connected in pressure tight fashion the receptacle to be filled.
  • the outlet of the filter compartment is blocked and negative pressure applied via an outlet connection or stud to the receptacle.
  • the outlet of the compaction compartment After reaching a certain negative pressure the outlet of the compaction compartment is suddenly opened and the material located within the compaction compartment flows at high pressure into the receptacle. At that location this material simultaneously serves for the further compaction of the material which is already located within the receptacle.
  • a negative pressure can be applied to the compaction compartment, accelerating sucking-up of pulverulent material out of the supply container.
  • the filter device can also be impinged with an overpressure by carrying out a suitable switchingoperation, this overpressure, during a second phase of the filling operation, supporting the further filling of the evacuated receptacle.
  • a drawback of this known equipment resides in the fact that it is necessary to provide a mouthpiece which is exactly accommodated to the receptacle to be filled. Furthermore, it is only possible to fill receptacles possessing a rather rigid or sturdy wall capable of withstanding the negative pressures used for evacuation of the receptacle. Additionally, this prior art equipment is extremely limited as concerns its capacity since the two-phase filling operation requires a relatively large amount of time.
  • Still another and more specific object of the present invention relates to an improved apparatus for filling a receptacle with compacted pulverulent material which, while preventing the previously explained drawbacks of the prior art constructions and with the most simple design of the equipment, ensures for the greatest possible utilization of its capacity.
  • the inventive apparatus for the filling of a receptacle with compacted pulverulent material is manifested by the features that a supply compartment is arranged after the compaction compartment, the supply compartment having an outlet equipped with a dosing mechanism.
  • the receptacle itself is not utilized for the compaction of the pulverulent material, rather the already compacted material is filled into the receptacle, it is possible to resort to the use of receptacles of random construction and design, especially also those which do not possess any rigid walls capable of withstanding negative or sub-atmospheric pressures. Since the receptacle need not be connected in pressure tight fashion with the supply compartment there is also obviatedthe need of providing special mouth pieces and it is possible to fill receptacles possessing different construction and cross-section of their opening.
  • FIG. 1 is a schematic elevational view, the right-half of which is in section, of a preferred constructional form of apparatus for filling a receptacle or the like with compacted pulverulent material;
  • FIG. 2 is an enlarged sectional view through the double-wall of the compaction compartment with the filter mechanism dismantled

  • the compaction compartment 11 possesses a substantially cylindrical construction and is equipped with a double-wall jacket 14 embodying the inner wall 16 and outer wall 20, the inner wall 16 of which is constructed to provide a filter mechanism 15.
  • the internal crosssection of the outlet 13 is preferably at least as large as the internal cross-section of the compaction compartment 1 1.
  • the filter mechanism 15 which has been illustrated in detail in FIG. 2, embodies an at least partially perforated support wall defined by the inner wall 16, at the inner surface of which there is mounted a filter element 17 formed of flexible material. It is preferred if this support wall 16 only possesses perforations or apertures 18 at its upper region. The lower region of such support wall 16 is preferably continuous i.e. not perforated.
  • the filter mechanism is advantageously constructed as a filter insert for the purpose of facilitating cleaning, and which can be clamped by quick operating-closure mechanism 19 with the outer jacket 20 of the compaction compartment 11. At the upper end of the filter insert there is provided a pressure ring a carrying a sealing ring 22 bearing against a sealing lip 23 of the compaction compartment 11.
  • the flexible filter 17 is equipped at its upper and lower marginal edges with a respective flexible marginal bead or bulge portion 24, by means of which it can be clamped at the clamping rings 25 of the filter mechanism 15, the upper clamping ring 25 simultaneously functioning as pressure ring 25a.
  • the double-wall jacket 16, 20 of the compaction compartment 11 will be seen to contain a substantially ring-shaped intermediate compartment 26, at which there are selectively connectable, via the'closure or valve elements 27, 28 and 29, a negative pressure source, generally indicated by reference character 100,

  • this dosing mechanism 32 preferably incorporates an iris diaphragm 33.
  • dosing mechanism 32 is coupled with a weighing device or balance 34 upon which rests the receptacle or container 35 to be filled.
  • This balance or weighing device 34 is equipped with an adjustable pre-contact 36 and a main contact 37, at which the course and actual filling weight of the receptacle can be set.
  • the pre-contact 36 serves for partially closing the iris diaphragm 33 while the main contact 37 serves for completely closing such iris diaphragm.
  • a suitable suction mechanism 38 is also provided and such surrounds the outlet 31a of the supply compartment 31 and serves to promote the dustfree functioning of the equipment.
  • the inner cross-section of the supply compartment 31 is preferably at least as large as the inner cross-section of the compaction compartment 11 and its closeable outlet 13.

  • a control mechanism 39 which coordinates the individual functions of the components.
  • the mode of operation of the described equipment is as follows:
  • the inlet 12 from the silo 10 and the output 13 to the supply compartment 31 are closed and the closure or valve element 27 leading to the negative pressure source is opened so that a negative pressure is applied to the intermediate compartment 27.
  • an adjustable contact 300 at the pressure metering device 30 there is set a minimum negative pressure, and when reaching such minimum negative pressure the inlet 12 is opened.
  • the pulverulent material flows in the presence of negative pressure out of the silo 10 into the compaction compartment 11.
  • the inlet 12 is automatically closed.
  • Application of suction to the compaction compartment 11 by means of the negative pressure source 100 is continued until the pressure metering device 30 reaches a further adjustable contact 30b, so that by means of the negative pressure source so much air entrapped in the material within the compaction compartment 11 has been sucked-off that sufficient compaction of the material has been realized.
  • the valve or closure element 27 leading to the negative pressure source closes and the closure element 29 leading to atmosphere opens, in order to now communicate the compaction compartment 11 with the atmosphere 102.
  • a further timing element of the control mechanism 39 ensures for the closing of the valve or closure element 29 and opening of the valve or closure element 28 leading to the compressed air source 101.
  • the throughflowing gas thus cleans the filter mechanism by a flushing action and arrives at the compaction compartment 11 where it protectively arranges the loose particles of pulverulent material without additionally mechanically loading same and compresses such material into a smaller volume.
  • the outlet 13 is opened, either by controlling same via the pressure metering device 30 or through a further timing element, and the compacted pulverulent material is removed or ejected into the supply compartment 31.
  • Inlet and outlet are preferably coupled with one another in such a fashion that upon opening one the other is locked so as to prevent any erroneous operations.
  • filling level indicator which upon reaching a maximum filling condition interrupts the compaction operation and again initiates same when a minimum filling condition is present.
  • the receptacle or container 35 is placed upon the weighing device 34 beneath the outlet 31a of the supply compartment 31.
  • a suitable tare switch at the weighing device 34 triggers an automatic filling operation.
