Definitions

  • the present invention relates to an arrangement in containers for rod-shaped objects lying parallel to each other, especially cigars or cigar bunches, and provided with a discharge shaft located in the bottom of the container, which shaft is movable back and forth in relation to the container in the transverse direction of the objects.
  • the bottom of the container comprises a cylindrical surface of a piston, which can be rotated back and forth and which is provided with a diametrically located discharge shaft.
  • the objects are largely prevented from arching by the fact that the inlet opening of the shaft in the container bottom is movable back and forth.
  • the object of the present invention is to effect an arrangement in which the above inconveniences are eliminated and which, in addition, can be implemented with substantially smaller demands on space.
  • the bottom of the container comprises two longitudinally extending members made of a highly flexible material, extending in the transverse direction of the objects and suitable for supporting them, each member being attached to one of two opposite sidewalls of the container and kept taut by a tensile force acting upon it.
  • Each member extends towards the other and around one of the two rollers rotatably mounted parallel to the objects and attached to a base part movable in relation to the container, with a distance between the rollers adapted to the width of the discharge shaft.
  • a substantial advantage of the invention is that the bottom of the container is essentially immobile in relation to the container. Thus no rotation is imparted to the objects on the container bottom when the shaft passes an object, the object will first drop down into the inlet opening of the shaft and then be raised up under positive influence from the support members at the edges of the shaft, the movement thus having the character of a continuous wave motion.
  • the two support members may each comprise a broad belt of rubber or plastic, for example, or two parallel thin belts or strips, the support members being provided with thin ends, which are wound around the respective rollers.
  • the rollers may also be constructed as pulley rollers and the support members wound round separate wind-on and wind-off rollers rotatably mounted in the movable base section.
  • the rollers used for winding the support members on and off must in both cases be driven, this being suitably effected by providing the support members with sprocket wheels meshing with a chain, which is firmly fixed in relation to the container, or a corresponding transmission, e.g. a gear wheel and rack.
  • the rollers may also be mutually connected by a chain, the wind-on roller being driven by the wind-off roller.
  • the support members can be kept stretched more easily if they are connected to the container, or a part, which is connected to it, by means of resilient fastening members.
  • Driving the wind-on and wind-off rollers during simultaneous elastic stretching of the support members can also be effected by applying a continuously operating torque to the rollers, e.g.
  • torsion can be effected by means of resilient members placed between the wheels and the rollers.
  • each support member extends around one of two additional rollers mounted on the movable stand section, each support member having a free end firmly connected to the container or the end of the same member, which is connected to the containers sidewall.
  • This embodiment requires the same space in the direction of movement of the movable stand section as the known arrangement with the rotary piston described above.
  • a reduction of the demand on space can easily be achieved, however, by connecting the two support members with each other via pulley rollers firmly fixed in relation to the container, to form a single endless loop.
  • the carrier member comprises a single wide belt
  • the loop must normally extend around the top of the container.
  • the loop can be divided into two arbitrarily placed branches running on either side of the container.
  • FIG. 1 is a vertical projection, partly insection, of an arrangement for filling a belt provided with press compartments and advanced step'by-step, with cigars;
  • FIG. 2 shows in section an example of the means of driving a wind-on and wind-off roller taken along lines II-ll;
  • FIG. 3 is a section through the belt with the press compartments in FIG. 1 taken along lines III-III;
  • FIG. 4 shows a modified form of the wind-on and wind-off rollers in FIG. 1;
  • FIGS. 5-8 show a further four embodiments in the same projection as in FIG. 1.
  • FIG. 1 The arrangement shown in FIG. 1 has a stand 1, on which a container 2 for cigars is placed.
  • a movable stand section 4 is mounted so that it may slide along two guides 3.
  • a wide rubber belt 5 is fixed in the stand 1 by means of springs 6 attached at 6' and 11' to the stand 1.
  • the belt 5 extends from the lower edge of a wall 7 of the container 2 around a pulley roller 8 rotatably mounted on the stand section 4 and is then wound around a roller 9 likewise rotatably mounted on the stand section 4 and to which this end of the belt 5 is fixed.
  • a belt 10 is fixed by one end in the stand 1 via springs 11.
  • the belt 10 extends from the lower edge of a wall 12 of the container, around a pulley roller 13, which is rotatably mounted on the stand section 4 and is wound on to a roller 14, likewise rotatably mounted on the stand section 4.
  • the stand section 4 is further provided with a pulley roller 15 across which runs a belt 17 provided with press compartments 16 and two pulley rollers 18, which abut the upper side of the edges of the belt 17 outside the press compartments in such a way that the belt 17 describes an S-shaped path.
  • the compartments 16 are enlarged and at this point on the stand section 4 is the outlet opening of a channel 19 firmly fixed to the stand section, for supplying cigars 20 to the press compartments 16.
  • the upper end of the channel 19 is located in the space between the pulley rollers 8, 13 through which the cigars 20 fall down into the channel 19.
  • the belt 17 is intended to be driven step-by-step, for example in the direction shown by an arrow 21, cigars being supplied to the press compartments 16 only during the idle periods.
  • a latching arm 22 with a iatching plate 23 is mounted on the stand section 14 and can be pivoted between two stops 24 so that the latching plate 23 can be inserted beneath the lower outlet opening of the channel 19.
  • a rectilinearly reciprocating arm 25 is hinged to the latching arm 22 to drive both the movable stand section 4 and the latching arm 22.
  • the wind-on and wind-off rollers 9, 14 are each provided with a sprocket wheel 26 firmly attached to the roller, which sprocket wheel rolls into engagement with a chain 27 firmly attached to the stand 1 when the movable stand section 4 moves, the initial rotational setting of the rollers 9, 14 being so adjusted that the belts 5, 10 are stretched to the necessary extent.
  • FIGS. 1-3 operate in the following way. While the belt 17 is at rest, the arm 25 is moved by a mechanism, not shown, in the direction indicated by an arrow 28, the arm 22 and the latching plate 23 being drawn into abutment with one of the stops 24 so that the pile of cigars 20 in the channel 19 slide downwards a short distance and rest with the lowest cigar located in a compartment 16, after which the movable stand section 4 with the rollers 8, 9, 13, 14, and 18 and the channel 19 are set in motion.
  • the compartments 16 are enlarged one after the other by the rollers 15, 18 and each receives a cigar 20 from the channel 19.
  • the belt 10 is wound off the roller 14 and the belt 5 wound onto the roller 9 while cigars fall down into the shaft between the rollers 8, l3 and the walls of the channel 19 as cigars are inserted into the compartments 16.
  • the movement is interrupted and the am is moved in the opposite direction.
  • the latching arm 22 is pivoted by arm 25 anticlockwise to abut the other stop 24, the latching plate 23 being inserted under the lower outlet opening of the channel 19 and stopping the downward supply of cigars, after which the movable stand section 4 executes a return movement until the shaft is close to the wall 12.
  • the belt 17 Before the work cycle described above can be repeated, the belt 17 must be advanced to step encompassing all the compartments 16 filled during the preceding work cycle, this taking place most conveniently during the return movement of the stand section section 4. If the speed, at which the belt 17 is advanced, is not too great, the relative speed between the belt 17 and the stand section 4 may be sufiiciently low to permit the downward supply of cigars into the compartments 16 during the return movement of the stand section 4 as well, the latching means 22, 23 then obviously being removed.
  • the wind-on and wind-off rollers 9, 14 can be moved up to the position of the pulley rollers 8, 13 as shown in FIG. 4, this reducing the demand on space.
  • FIG. 5 shows a further modification of the arrangement illustrated in FIGS. 13, each carrier member 5, 10 being arranged to form an endless belt.
  • the wind-on and wind-off rollers 9, 14 in FIG. 1 have been removed and the belts 5, 10 have been drawn around two further pulley rollers 29, 30 rotatably mounted on the stand section 4 and both ends of the belts have been attached directly in the container 2.
  • the stand section is mounted on pins 39, which project from the end walls of the stand section 4 and is provided with an arm 40 to which a reciprocating actuating arm 41 is hinged.
  • the pivotal stand section 4 may also be mounted on pins located higher up on the stand section 4, at half the height of the channel 19 for example, and be provided with known means for discharging an object in one or both pivotal positions.
  • the invention can also be applied to advantage in cigarette packing machines, in which it has thus far been difficult to achieve a sufficiently even flow of cigarettes from a container down through several parallel feed channels. Irregularities in the flow have been caused primarily by a strong tendency for the cigarettes to arch in the container and by an adverse effect of the devices used to overcome this arching, which devices interfere with the downward supply of cigarettes into the upper opening of the channels.
  • a batch of cigarettes is pushed over from the lower part of the channels to a stationary container on a conveyor belt, which is movable step-by-step.
  • the shaft comprising several channels, and the container can be constructed in accordance with what was shown in FIG. 1 for example.
  • the transfer of the batches of cigarettes may conveniently take place when the shaft is halfway between the walls 7 and 12 and the movable stand section 4 can be constructed to move alternately towards one wall and the other 7, l2 and back between the transfers to fill cigarettes into the channels of the shaft.
  • the shaft 19 is divided into a plurality of channels by partition walls 42 at the upper edges of which rollers 46 are rotatably mounted parallel to the cigarettes 20 and that the batches of cigarettes are discharged in the longitudinal direction of the cigarettes from the lower part of the shaft 19 to.
  • the discharge of a batch of cigarettes is arranged to take place while the movable stand section 4 is moving in the direction indicated by an arrow 45, which also indicates the direction of movement of the belt 44, with the lower part of the shaft 19 located directly in front of a holder 43.
  • the piston of the discharge mechanism When the batch of cigarettes has been placed in the holder 43, the piston of the discharge mechanism is drawn back and the stand section 4 moved back towards the wall 7 while the channels are filled with cigarettes.
  • the time available for filling the lower part of the channels with cigarettes is substantially greater than in the case where the batches of cigarettes are transferred from a stationary shaft to a moving holder by a movable carriage which, in principle, comprises the lower part of the shaft, as the cigarettes are fed into in an extremely short period when it is at rest in its starting position.
  • the rollers 46 are suitably driven by a rubber belt or the like driven by one or'both of the rollers 8, 13, in such a manner that the direction of rotation and peripheral speed of the rollers 46 is the same as the direction of rotation and peripheral speed of the rollers 8, 13.
  • rollers 9, 14 are driven either in the same manner as that shown in FIG. 1 or in one of the ways mentioned in the introduction.
  • the rollers 8, 13 may also of course be dispensed with and replaced by the rollers 9, 14 as shown in FIG. 4.
  • An apparatus for discharging from a container rodshaped objects, especially cigars, cigar bunches, or cigarettes, lying parallel to each other and to two opposite sidewalls of said container, each of said sidewalls having a bottom edge comprising a stand supporting said container, a movable stand section, means for journalling said stand section beneath said container, two spaced rollers having axes of rotation positioned in parallel with said objects, means to rotatably journal said rollers on said stand section, support means of easily flexible material attached to said stand and extending at least from said bottom edges of saidsidewalls to said rollers and around at least a .portion of said rollers, means for keeping said support means of easily flexible material taut, said support means forming a bottom of said container and presenting an inlet opening of a discharge shaft defined by the interspace between said rollers, and means for moving said stand section to and from between positions in which the inlet opening of said discharge shaft is positioned adjacent said bottom edges of said sidewalls.
  • rollers are designed as pulley rollers and that said support means are wound around wind-on and wind-off rollers which are rotatably mounted in the movable stand section and driven by a mechanism for tauting said support means.
  • said support means comprise two endless belts extending around said rollers and for each belt a further roller mounted on the movable stand section.
