Definitions

  • ABSTRACT A device for sorting and packing round-bar-shaped or tubular articles and, more particularly, cigarette tubes or cigarette filter tubes.
  • the device comprises a funnel-shaped container the downwardly tapering portion of which terminates in a chute having a bottom, side walls and a front wall, the front wall being designed as an ejector and the rear wall having an ejector orifice; a cut-off slide, or a plurality of cut-off slides arranged in pairs, and disposed between the container and the chute which serves as a batching chamber; and a belt which rests flatly on the bottom of the chute at right angles to the longitudinal axes of articles in the chute and/or on the inner surfaces of the side walls of the chute.
  • the belt is adapted to be reciprocated or gradually moved by means of an external drive mechanism.
  • the belt may be arranged with one end thereof outside the chute and attached to a fixed support such as the frame of the device and with its other end resiliently connected to a motion-imparting device adapted to impart a motion to the belt in the longitudinal direction thereof.
  • a motion-imparting device adapted to impart a motion to the belt in the longitudinal direction thereof.
  • the invention relates to a device for sorting and packing round-bar-shaped or tubular articles, especially cigarette tubes or cigarette filter tubes.
  • the present invention contemplates the provision of a device comprising a funnel-shaped container, the downwardly tapering portion of which terminates in a chute bounded by a bottom, the front wall of said chute being designed as an ejector and the rear wall having an ejector orifice and one cut-off slide or several cutoff slides arranged in pairs between the container and the chute, which serves as a batching chamber.
  • a belt rests flatly on the bottom of the chute at right angles to the tubes in the chute and/or on the inner surfaces of the side walls of the chute and the belt is reciprocated or gradually moved by means of an external drive.
  • the belt is arranged with one end thereof outside the chute and attached to the frame of the device by means of a tension spring element and with its other end connected to a motion-imparting device adapted to act in the longitudinal direction of the belt.
  • the individual tubes adjoin one another as closely as possible and are positioned so as to fill any gaps.
  • the invention thus ensures that upon dividing the tubes by the cut-off slide any tubes which are obliquely shifted in the container do not drop into the chute in this inclined position in which position they would take up so much space that the number of tubes dropping into the chute thereafter would not correspond to what would completely fill the chute. Moreover, any tubes disposed in an inclined position can interfere with the working cycle during the ejecting operation. 4
  • the device according to the present invention can be simplified if, instead of the non-extensible belt, there is used a belt which is elastically extensible in its longitudinal direction and which acts directly on the frame of the device with its one end and is connected at its other end to a motion-imparting device adapted to impart a reciprocating motion to the belt.
  • the motion-imparting device can be in the form of a mechanicalcrank gear coupled with the drive of the machine. However, it is also possible to use an electromagnetically driven vibrator as the motion-imparting device.
  • the width of the belt can vary.
  • filterless tubes it is expedient to adapt the width of the belt to the length of the tubes in order to avoid damage to the sensitive tubes.
  • filter tubes it is preferable to adjust the width of the belt to the length of one filter and to arrange the belt in the region of the filters.
  • the belt it is also conceivable to design the belt as a narrow strip and to arrange it approximately in the mid region of the tubes.
  • a further problem encountered heretofore is solved in that above the chute, in the region of the tube ends, there is provided a slot nozzle for blowing air on to the tubes ready for ejection.
  • the slot nozzle is inclined downward and extends over the width of the chute.
  • The. air blast is directed on to the tube ends before the tubes are separated from one another by means of a cutting knife and while the tubes in the batching chamber are ejected by means of an ejector slide into a waiting container. In this manner the position of the individual tubes is stabilized and the tubes are prevented from shifting to an inclined position. While thetubes are dropping from the funnel-shaped container into the batching chamber the air blast is interrupted.
  • a plurality of nozzles disposed adjacent one another may be provided.
  • FIG. 1 is a vertical section of one embodiment of a device according to this invention:
  • FIG. 2 is a view, partly in section, taken along the line II-II of FIG. 1;
  • FIG. 3 is a diagrammatic representation of the device in FIG. 1 which shows the separation of the tubes in the batching chamber from the container.
  • a funnel-shaped drawingoff container 11 for the cigarette tubes is designed as a replaceable magazine for the tubes (not shown in detail in the drawings) while its lower, smallerorifice can be detachably connected to a chute 13.
  • the width of the container 11 and that of the chute l3 correspond to the length of one tube.
  • An ejector for the tubes is disposed in the front wall 15 of the chute 13 in the lower region of said wall.
  • the ejector 17 is movable on a rod 16 in the longitudinal direction of the tubes.
  • the length of the sheet cover 18 can also be increased depending on the length of stroke of the ejector 17.
  • the height of the upper edge of the ejector 17 is so chosen that a specific layer 19 of the tubes 12 which are arranged and staggered in individual layers in the chute 13, projects above it.
  • the ejector orifice 20 in the rear wall'2l is bounded on its upper edge by a guide strip 22.
  • the guide strip 22 is in the upper region of the tube layer 19 and has a butting face23 directed toward the tubes.
  • the guide strip 22 also is a component of a feed channel 27 for the tubes 12.
  • a packing container 28, such as a buckettype chute or thelike, for receiving the ejected tubes is arranged behind the feed channel 27.
  • the lower portion of the chute 13 is closed by a bottom 32.
  • the bottom 32 is vertically adjustable and lockable by means of an adjusting mechanism 14, so that tubes of different lengths can be ejected.
  • the height of the ejector 17 is then adapted to the changed position of the bottom 32 this can be done simply by changing the ejector 17.
  • a thin non-extensible belt 40 rests flatly on the bottom at right angles to the cigarette tubes 12.
  • One end of the belt 40 is secured to a frame 42 by means of a tension spring 41.
  • the other end of the belt 28 acts on a mechanical crank gear 44 by way, of a coupling 43.
  • angle sheet irons 45 which are laterally adjustable in the bottom 32, are provided so that when widening the chute 13 the bottom surface can be increased correspondingly.
  • the outer ends of the belt 40 pass through apertures 46 provided in the angle sheet irons 46.
  • Guides 48 are provided on the opposed side walls 47 of the chute 13. Slides 49 and 50, which are movable toward one another and which separate a specific number of filter tubes from the container 11, are guided in the guides 48. The width of the slides 49 and 50 only slightly exceeds the length of a filter.
  • a slot nozzle 51 which is inclined with respect to the ends of the filter tubes, is arranged above the chute 13 on the rear wall 21.
  • the slot nozzle 51 is adapted to direct an air blast at the filter tube ends before commencing the tube ejecting operation.
  • the tubes are thus stablized in their position.
  • a plurality of slot nozzles 51 extending side by side over the width of the chute may be provided in order to exert an air blast against the entire line of tube.
  • Vibrators 26, which facilitate directing the tubes dropping from the container 11 into the chute 13, to individual superjacent staggered layers, are secured to the side walls 43 of the chute 13.
  • the tubes dropping from the container 11 into the chute 13 are at first loosely packed in the chute 13 and are not accurately positioned so as to fill gaps. However, because of the reciprocating motion of the belt 40 acting on the crank gear 44 at least the lower tube layers are laterally reciprocated and at the same time are subjected to a slight rotary motion about their own axes.
  • the tubes in the chute are thus quickly and accurately aligned in a simple manner and an optimum volume of tubes for filling the batching chamber is thus obtained.
  • the tubes in the chute are then separated from the container by means of the cut-off slides 49 and 50.
  • the slide 49 is partially moved between the cigarette tubes 12. Thereafter, the slide 50 is also moved between the tubes 12 from the opposite side but to such an extend that it approaches the slide 49 to within a distance therefrom which is slightly smaller than the diameter of one tube.
  • the slide 50 pushes the slide 49 out of the container 11 until it alone covers the entire cross section of the chute. Tubes lying between the slides are pushed either into the container 11 or into the chute 13. Since the slides seize the tubes only at their filter ends, it can happen that a tube is moved into an inclined position and even upon the subsequent filling of the chute 13 this tube would remain in an inclined position in the chute and would thus prevent optimum filling of the chute 13.
  • the ejecting operation would be obstructed by the inclined tube.
  • the reciprocating motion of the belt 40 takes care of aligning such inclined tubes in parallel with the other tubes. An optimum degree of filling in the chute is thus obtained.
  • the tubes in the chute are pushed by the ejector 17 by way of the feed channel 27 into a packing container kept in readiness.
  • the slot nozzle 51 directs an inclined air blast at the ends of the tubes 12 from above, so that the tubes can be easily pressed downward and are stabilized in their position for ejection.
  • the guide strip 22 may be replaced by a brush strip, as a braking device for the tube layer lying above the layer 19.
  • the sheet cover 18 on the ejector l7 prevents the tubes from dropping down from the container 11 during the ejecting operation. Only when the ejector is again in its initial position do tubes drop from the container 11 into the chute 13.
  • this type of packing device it is expedient either to adapt the belt 40 to the length of the filterless cigarette tubes or to design it as a narrow belt and to so arrange it in the mid-region of the filter tubes that it rests flatly on the bottom 32.
  • the device according to the invention it is thus also possible to reciprocate the belt as an endless belt or to accelerate it continuously and in addition gradually increase or retard its speed.
  • a device as claimed in claim 1 wherein a plurality of cut-off slides is provided with the cut-off slides arranged in opposing pairs between the container and the chute.
  • a device as claimed inclaim 1 characterized in that one end of the belt is attached to a frame by means of a tension spring element and the other end of the belt is connected to a motion imparting device adapted to impart reciprocating motion to the belt in the longitudinal direction of the belt.
  • a device as claimed in claim 1 characterized in that the external drive mechansim comprises a mechanical crank gear and a coupling connecting said belt and said mechanical crank gear.
  • a device characterized in that the width of the belt corresponds to the length of the filter of a cigarette tubeand that the belt is disposed in the region of the tube filters on the bottom of the chute.
  • a device characterzed in that the belt consists of a narrow strip and is arranged approximately in the mid-region of the cigarette tubes.
  • a device especially according to claim 1 characterized in that a nozzle for blowing air onto the tubes ready for ejection is provided above the chute in the region of the tube ends, said nozzle being inclined downward and extending over the width of the chute.
  • a device characterized in that the nozzle extends over the width of the chute and is formed by several individual nozzles arranged side by side.
  • a device characterized in that the air blast from said-nozzle is interrupted during the time in which the tubes drop from the funnelshaped container into the batching chamber.
