  • This ar- UNITED STATES PATENTS rangement ensures that incoming cigarettes have no drop to 2.592.642 4/1952 Bardet 221/9 X the top layer, which could result in unwanted misalignments.
  • the invention relates to a device for cigarettecontainersof the type having an upper feed-in opening and a lower feed-out opening for cigarettes and the storage capacity of which isvariable depending on alterations in the ratio between cigarettes fed in and cigarettes fed out, at least one .wall part of the container being displaceable by means of a driving motor and the feed-in opening being limited by at least one stripshaped, flexible-covering member arranged to rest on the top 1 layer of cigarettes in-the container.
  • Cigarette containers of the type described are already known, for example through German Pat. No. 1,103,838-and- U.S. Pat. No. 3,341,036.
  • a feeding means comprising two belt conveyors, cigarettes being held between thebelts and fed at an adjustable speed directly to the upper layer of cigarettes.
  • the covering member is light and freely movable and that its movements due to alterations in the upper layer of cigarettes are sensed by means of an electric sensing member which is stationary in'relation to the feed-in opening and is arranged to be influenced by alterations in an' air gap between the upper surface of the covering member andthe sensing member, and when influenced,regulates the driving motor so that the air gap is kept substantially constant.
  • the container is arranged to receive a slightly greater number of cigarettes than the number fed out and consequently the flexible strip or sheet covering the cigarettes near the feed-in opening will be raised a little after a while since the number of cigarettesin the container increases.
  • the air gap is thus reduced and the sensing member starts the driving motor, thereby increasing
  • the simplified view of the device shown in H6. 1 comprises a known-cigarette container 1 havinga stationary part in communication'with a cigarette packer 3, not shown in detail, at a feed-out opening 54.
  • the stationary part consists of sidewalls 2'-r:onverging towards the feed-out opening 54 and becoming at the top vertical sidewalls 4.
  • the width of the sidewalls 2 and 4 only slightly exceeds the length' of Y the.
  • Thesidewalls 2 and 4 are joined attheedges to front and :rear walls notshown in the drawings.
  • the movable sidewalls 5 are preferably the same width as the walls 2 and 4.
  • the left-hand sidewall 4 is provided with a flange 81 on the upper side of which run rollers 9 on the trolley 7.
  • the right-hand wall 4 is provided with a flange 11 and a flange 12, perpendicular thereto.
  • the trolley 8, driven together with the trolley 7, is provided with rollers 13 running on the flange 12 and is guided laterally to the flange 11.
  • the right-hand movable wall 5 is joined to the trolley 8 via a link 14 and a link 15 pivotally connected to the link 14.
  • Theleft-hand trolley 7 is connected via a connection member 16 to an endless chain'l7 running on two chain wheels 18 and l9'arranged vertically one above the other.
  • the chainwheel 19 is rigidly connected to a chain wheel 20 driven by means of a chain 21 from a chain wheel 22 on a driving motor 23.
  • This driving motor 23 is regulated both by a mechanism, .not shown in the drawings, which operates in coordination with the packer 3 and a machine, not shown I here, for feeding incigarettes, and also through conduits 24,
  • the covering strip isalways in contact with the upper layer of cigarettes and keeps the cigarettes parallel.
  • the strip has fallen to the predetermined level sothat the width of the airgap is, for example 5 mm.', the output signal from the sensing member to the motor ceases and movement of the container parts ceases.
  • FIG. 1 is a simplified view of a container, showing the essential parts
  • FlGS. 2-4 show the principles of a number of different types of sensing members.
  • control equipment 26 which receives control signals via a cable '27 from a sensing member 28 which is further described later.
  • the link 14 connected to the trolley 8 is joined by a pivot 29 to a pivotingconveyor 30 for the cigarettes, which is of conventional design.
  • the conveyor 30 has two belt conveyors 31, 32 between which cigarettes are fed laterally from a continuous machine, not shown here.
  • the conveyor belts 31 and 32 of the "feeder 30 are of flexible material such as, for example, foam rubber or foam plastic, so that the cigarettes are firmly held during transport without the risk of being damaged.
  • the cigarettes are carried via the feeder 30 tothe inlet opening 33 of the container and are piled onto the upper layer of cigarettes or lined up in this layer.
  • the opening 33 in the embodiment shown hasa width approximately corresponding to the width of two cigarettes, but it may have any width depending'on the feeder used.
  • At least one lightand flexible sheet or a covering member 35 is arranged in direct connection with the inlet opening 33 and rests freely movablyon the upper layer 34 of the container.
  • the covering member '35 in the embodiment shown consists of a strip having one end joined to a bracket 36 on the feeder 30, this bracket also carrying the sensing member 28. This stationary endof the covering strip 35 is immediately adjacent to one longitudinal edge of the opening 33.
  • the strip 35 preferably has a width'corresponding to the length of the cigarettes, but it may even be narrower.
  • the free end 37 of the covering strip 35 is in gliding contact with an inner wall 38 of the trolley 7, this wall 38 being a continuation of the flexible sidewall 5 of the container.
  • the sensing member 28 Upon alterations in the airgap 40, the sensing member 28 is arranged to emit a signal to the equipment 26 which, in
  • FIG. 1 shows the covering strip 35 in its normal position, there being a certain airgap 40 and the sensing member 28 being inoperative. Since the feed-in rate of the cigarettes is slightly greater than the feed-out rate, as mentioned, the covering strip 35 will be raised by the increased number of cigarettes in the container as the upper layer 34 is raised, and the airgap 40 will thus be reduced.
  • the sensing member 28 will emit a signal to the equipment 26, thus activating the motor 23 and the trolley 7, together with the trolley 8 cooperating with it, will be moved slowly vertically upwards.
  • the feeder is pivoted clockwise via the link 14 and the sensing member 28 is thus also moved upwards, always assuming a specific position in relation to the opening 33.
  • the capacity of the container 1 increases and the covering strip 35, which is resting all the time on the upper layer 34 of cigarettes, is lowered.
  • the airgap 40 thus increases until the predetermined width of the gap is achieved, whereupon the sensing member 28 becomes inoperative and the slowly operating motor 23 is cut out. Consequently, during the movement of the displaceable part of the container, irrespective of how great this movement is, the upper layer of cigarettes will be in constant contact with the covering strip 35 and the cigarettes will not be pivoted from the parallel position.
  • a switch may be arranged to be actuated by the equipment 26, for example, so that the movement of the motor 23 in response to signals from the sensing member 28 is reversed, and when the airgap decreases the trolley 7 will be moved downwardly.
  • the supply of cigarettes to the opening 33 is interrupted for a certain period of time. This period may last until, for example, the minimum capacity of the container has been reached, after which a lower switch activated, for example, by the trolley 8, once again initiates the supply of cigarettes to the inlet opening 33 and influences the equipment 26 so that the original process is repeated.
  • FIG. 2 shows schematically an emitter 28, the output signals of which are dependent on the field between two capacitor plates 41 and 42, and more exactly, on alterations in dielectric constant of the capacitor formed by the plates 41 and 42. This is also affected by the covering strip 35 by way of the airgap 40 and when this airgap 40 reaches a certain minimum value the capacitance of the capacitor is altered so that the circuit (not shown in detail here) in the emitter 28 of which the capacitor is a part has its Q-value altered so that an output signal is effected in the equipment 26.
  • FIG. 3 shows a simplified view of another type of emitter having a coil 43 which is included in a resonance circuit in the emitter 28, the Q-value of which is altered in response to the movement of the covering strip 35.
  • the covering strip 35 is provided with an area 44 which is coated with a layer of-rriaterial which can be magnetized limiting one side of the airgap 40.
  • the layer 44 which may extend over the entire covering strip 35 or only within the area near the airgap,- may consist of a thin metal foil, a thin, light metal sheet or the like.
  • FIG. 4 shows a simplified view of a third type of emitter having magnetic pole shoes 45, 46 lying on one side of the airgap 40 and a metal layer or sheet of metal 47 arranged on the so that the motor 23 starts.
  • sensing means described above which sense the movement of the covering strip without any mechanical activation from the strip, are known per se and besides the sensing members illustrated in FIGS. 24 there are many other known types which operate in response to alterations in an airgap between the sensing member and the objectto be sensed.
  • Device in cigarette containers of the type having an upper feed-in opening and a lower feed-out opening for cigarettes and the storage capacity of which is variable depending on alterations in the ratio between cigarettes fed in and cigarettes fed out, at least one wall part of the container being displaceable by means of a driving motor-and the feed-in opening being limited by at least one strip-shaped, flexible covering member arranged to rest on the top layer of cigarettes in the container, characterized in that the covering member is light and freely movable and that its movements due to alterations in the upper layer of cigarettes are sensed by means of an electric sensing member which is stationary in relation to the feed-in opening and is arranged to be influenced by alterations in an airgap between the upper surface of the covering member and thesensing member and, when influenced, regulates the driving motor so that the airgap is kept substantially constant.
  • the sensing member is arranged to generate an electric field in the airgap and, upon alteration of the airgap, a corresponding alteration is effected in the electric field, which then influences the output signal of the sensing member to the driving motor.
  • Device characterized in that the feed-in of the cigarettes is greater than the feed-out and that the sensing member is arranged to be activated when the width of the airgap falls below a predetermined value.
  • Device characterized in that the covering strip, at least within a limited area, has a coating of metallic material, said coating limiting one side of the airgap.
  • Device characterized in that the coating consists of a material which can be magnetized and the covering strip of a nonmagnetic material.
  • Device characterized in that the feed-in of the cigarettes is greater than the feed-out and that the sensing member is arranged to be activated when the width of the airgap falls below a predetermined value.
