Definitions

  • the present invention relates to apparatus for laying down on a conveyor a plurality of articles of predetermined height, which constitute a pile guided in a descending conduit terminating just above said conveyor.
  • the apparatus according to the invention comprises likewise a descending conduit provided with a lateral aperture through which the thread of a screw is adapted to project into said conduit, said screw being rotatably mounted about a shaft parallel to said conduit and having a pitch increasing in the downward direction.
  • the apparatus according to the present invention is specially intended for handling articles having a greater diameter at the base than at the top, such as necked bottles or containers; the screw thread pitch increases in the downward direction by a value lower than the height of said articles up to a value greater than their height.
  • the initially stacked articles are separated from one another in a gradually increasing manner by the screw-thread proper, without resorting, at the conduit inlet, to means separate from said screw for creating between the stacked articles a gap permitting the engagement of the first thread of said screw.
  • variable pitch screw may be driven from a motor. During each screw revolution one article is released, so that the rate of release of the articles on the conveyor is a linear function of the screw rotational speed. Under these conditions and in this case the apparatus provides a solution to the first two problems mentioned hereinabove.
  • FIG. 1 is a diagrammatic front view, partly elevational and partly sectional;
  • FIG. 2 is a similar side elevational view of the apparatus
  • FIG. 3 is a section taken along the line Ill-III of FIG. 1.
  • the apparatus' comprises a vertical distributing conduit l'consisting for example of a metal or plastic cylindrical tube having dimensions selected to ensure a proper guiding of the articles to be dispensed.
  • the pile of articles 2 is formed from above the apparatus to which they are supplied for example by a pneumatic conveyor (not shown) disposed upstream of the apparatus.
  • a window 3 extending between two rectilinear generatrices 4, 5 is formed in the conduit 1.
  • the screw 6 having its shaft 7 parallel to the conduit 1 is so disposed that the outer edge 9 of its thread moves very close to said generatrices 4,5 during the screw rotation, whereby the thread projects into the conduit 1 through said window 3.
  • the pitch h of the upper turn 10 of screw 6 is smaller than the height hl of the article 2 to be dispensed, as explained hereinafter.
  • the pitch H of the lower turn 11 is considerably longer than the height hl of the article 2.
  • the screw 6 is driven from a motor 12 at a properly selected speed.
  • the articles 2 consist of bottles having a neck portion of a diameter considerably smaller than the base diameter so that when these bottles are stacked and supported by one another in the conduit 1 with the necks at'the upper end of the articles it is possible to introduce a member, i.e. the upper outer edge 13 of the screw thread, into the space thus left under each bottle base, without causing this edge to contact the neck of the next underlying bottle.
  • the apparatus operates as follows:
  • the articles 2a, 2b are disposed above the screw 6 and article 2c engages this screw by having its bottom supported by the outer edge of the upper turn 10 of screw 6. Since the height hl of this bottle 20 is slightly greater than the pitch h of the upper turn 10 of said screw, the top of its neck lies above the upper level of the screw and supports the next bottle 2b. During the screw rotation the upper end 13 of upper turn 10 is caused to engage the bottom or base of bottle 2b from underneath, thus preventing this bottle from continuing its downward travel while the preceding bottle 20, in contrast thereto, keeps moving towards the lower end of conduit 1. To sum up, the thread of screw 6 is inserted between two adjacent bottles 2b and 2c.
  • the bottle 2c travels at a gradually increasing speed, since the pitch H of the lower turn 11 of screw 6 is greater than the pitch h of upper turn 10.
  • conduit 1 comprises at its lower portion a wider aperture 16 permitting the free transfer of the articles 2 to the underlying conveyor 15.
  • the motor 2 is dispensed with and the screw 6 can revolve freely about its axis.
  • the screw is caused to rotate by the weight of the pile of articles 2.
  • the operating characteristic of the apparatus may be adjusted, if necessary, by using either a very small auxiliary motor (directing for example a driving air jet against a suitable blading) or a friction brake.
  • a very small auxiliary motor directing for example a driving air jet against a suitable blading
  • a friction brake directing for example a driving air jet against a suitable blading
  • an essential requirement is that an article constantly bears with its bottom on the first turn of the screw thread so that the upper end of this article emerges somewhat above the level of the upper edge 13 of said turn to preserve a proper relative spacing of the successive articles, otherwise an article might become wedged by said edge 13.
  • An apparatus for laying down separately on a conveyor a series of articles of predetermined height, having a greater diameter at the top than at the base which comprises a descending conduit for guiding a plurality of stacked articles towards said conveyor, said conduit comprising a lateral aperture extending along one side thereof, a screw mounted externally of said conduit and adapted to revolve about an axis parallel to said conduit, said screw having a thread projecting through said lateral aperture, the pitch of said screw thread increasing in the downward direction from a value inferior to the predetermined height of said articles to a value greater than said height, whereby the screw thread is adapted, during the screw rotation, to separate the lower article of the pile from the other articles guided in said conduit, and to eventually lay down said articles so ar tel on said conve r.
