Definitions

  • FIG.2 METHOD FOR PACKAGING LOOSE FIBROUS MATERIAL FROM A CONTINUOUS FLOW Filed July 18, 1968
  • the invention is a continuation-in-part of my co-pending patent application Ser. No. 476,070 filed July 30, 1965 now abandoned, and refers to a method for pressing loose fibrous material which is supplied in a continuous flow, into packages of a predetermined constant weight, and more particularly for pressing loose tobacco in several portions which are subjected to equal pressure by successive compressions until the predetermined package has eventually been attained, and to an apparatus for performing this method.
  • the invention consists in such novel features, construction arrangements, combinations of parts and improvements as may be shown and described in connection with the method and the apparatus herein disclosed by way of example only and as illustrative of a preferred embodiment.
  • the basic idea of the invention is to solve the problem of compressing certain fibrous materials such as tobacco which tend to swell to a considerable extent, by a successive number of compressions of individually fed portions until the required quantity and weight of the package is attained.
  • Objects and advantages of the invention will be set forth in part hereafter and in part will be obvious herefrom or may be learned by practicing the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.
  • One of the objects of the invention is to provide a method by which the quantity for packaging of the tobacco is subdivided into as many sub-portions as the capacity of the pressing apparatus requires.
  • a further object of the invention is to provide a method by which the pressing apparatus is fed with such decreasing quantities instead of successive equal quantities, that the volume of material which is subjected to each compressing action, is constant, at least up to and including the next to last compression, while the final compression is performed on a volume which is equal to that of each one of the preceding compressions.
  • packaging contrivances including a level detector in the pressing apparatus, such as a photo-electric cell, arranged to stop the feeding of the tobacco to the pressing device and to actuate the compressing apparatus when the accumulated material has reached a certain level in the pressing apparatus.
  • a level detector in the pressing apparatus such as a photo-electric cell
  • FIG. 1 is a schematic plan view of the feeding system of the packaging press
  • FIG. 2 is a schematic side elevation of the packaging press
  • FIG. 3 is a schematic view of the upper plate feeding device of the press
  • FIG. 4 is a partial view of the final enclosure of the package.
  • FIG. 1 a conveyor 1, preferably one of the well-known, conventional belt conveyors, which feeds continuously, loose material to a distributing conveyor 2 having a hopper 3, 3' at each end thereof.
  • Conveyors of this type are equally well-known and conventional in the use for stockpiling material into silos.
  • Conveyor 1 is driven by an electric motor not shown in the schematic drawing, this motor being obvious and conventional and is not a part of the invention and is not claimed.
  • Conveyor 2 is driven by a conventional twospeed gear motor, also not shown in the drawing for the same reason as stated with relation to conveyor 1.
  • the drive of conveyor 2 can be reversed by reversing the direction of rotation of the gear motor.
  • conveyor 2 feeds alternatingly hoppers 3, 3'.
  • Scales 31, 31, schematically indicated, in FIG. 1, are arranged for support ing hoppers 3, 3'.
  • Scales 31, 31 have electric contacts, one intermediate and one final on maximum contact, both of which can be adjusted. Scales of this kind are wellknown, commercially obtainable, and per se do not form a part of this invention.
  • Two belt conveyors 9, 9 are arranged at right angles to conveyor 2. Conveyors 9, 9 are automatically loaded by delivery heads connected with scales 31, 31'. Each one of conveyors 9, 9" feeds the weighed material into a pressing apparatus, generally designated by numeral 10.
  • Press ing apparatus 10 has a body or stand 11 and a platen 12. Below body 11 is a plate 26 arranged for receiving the base 29 of the packing case, that is the bottom of the compressed package. Encasing plate 26 are four movable side panels 25, one on each side (two are shown in FIG. 2). Near the top of body 11 is a photo-electric cell 20.
  • a pusher 21 actuated by a fluid power motor 14, acting horizontally across body 11 for evenly planing the heap of material which has been delivered by conveyor 9.
  • a further mechanism is provided for automatically placing a lid or top plate 28 on top of the compressed package.
  • This mechanism consists of a fluid power motor for pushing one lid 28 at a time over a support plate 24 to cover the compressed package in body 11.
  • Lids 28 are stacked up and are supported by two sets of forks, 22, 23 which are arranged to be retracted alternatingly upon given cycle signals.
  • Loose material is fed by conveyor 1 over conveyor 2 into hoppers 3, 3.
  • the first contact on scale 31 causes the gear motor of the conveyor to step down to a much reduced speed for accurately completing the pre-set weight of the material on the scale.
  • the second or final contact on the scale causes the reversal of the gear motor and the shifting back of the gear to the higher speed.
  • Conveyor 2 then is feeding into the other hopper on the other scale. At the same instant the weighed portion of the material is delivered from the scale to conveyor 9 (or 9') which then carries the material to the press 10.
  • Conveyors 9, 9' may be arranged for shuttling the material rather than continuously delivering it in a single flow.
  • photo-electric cell acting as a level detector causes the emptying of hopper 3 onto conveyor 9 to be stopped and also stopping of the conveyor.
  • pusher 21 levels the heap in body 11.
  • platen 12 is set in motion for a first compressing of the first filling.
  • a photo-electric cell 20 becomes again free, the feed is automatically restarted. This cycle is repeated until the scale 31 of hopper 3 has returned to zero. At this point a delay relay is activated for the next following operations.
  • Pusher 21 makes one more levelling movement.
  • first set of forks 22 is retracted for dropping one lid 28 which is immediately pushed over plate 24 onto the top of the material in body 11. While forks 22 return to their starting point, forks 23 are withdrawn letting the pile of lids drop and thereupon return for intercepting the pile above the now lowermost lid. With lid 28 in place on top of the material, and the timed delay of the relay being expired, a last compression of the material with the lid 28 on top of it takes place whereupon platen 12 remains in the lowermost position while side panels 25 are returned to their initial position. There is then sufiicient space to place a wrapper 27 consisting preferably of four articulated panels around the package. Lid 28 and base 29 are kept together by battens 30 extending over the entire length of lid 28 and base 29, (FIG. 4). Eventually the finished package may be carried off to a stacking area. This last operation does not pertain to the invention.
  • a method for compressing and packaging predetermined quantities of loose fibrous material, particularly tobacco, and maintaining said material in a compression condition within a container comprising the steps of (1) feeding quantities of tobacco of predetermined weight and volume to a compactor,
