Definitions

  • the invention relates to a revolver with pockets arranged along the circumference for receiving objects, in particular packs, the pockets being delimited by at least two approximately parallel side walls which can be moved relative to one another in order to enlarge or reduce the cross section of the pockets.
  • Revolvers are rotatingly driven organs for the transport of packages or package contents in connection with packaging machines.
  • a revolver is provided with pockets on the outer circumference, each of which contains the contents of the pack or the packs, which may have already been partially completed.
  • the packaging manipulations are carried out on these, in particular folding processes as well as welding or gluing of blanks.
  • the centrifugal forces can lead to the undesired relative displacements within the pockets. This is especially true if the package contents, e.g. B. a single item, with considerable play in the pack is included.
  • the invention is based on the object of developing and developing a revolver of the type described in the introduction such that displacements of packs and other objects within the pockets of the revolver are avoided even at high rotational speeds.
  • the revolver according to the invention is characterized in that the side walls are each connected to different, independently movable partial revolvers.
  • the partial revolvers are preferably rotatable relative to one another about a common axis.
  • An actuator can be controlled so that the partial revolvers - and thus the side walls of the pockets - perform a short relative stroke to one another during the standstill phases, so that the cross-section of the pockets is slightly expanded or narrowed.
  • the objects or packs can be inserted or ejected into them.
  • the cross section of the pockets is narrowed so that the contents of the pockets are fixed under clamping action. This prevents the objects or packs from being able to be moved in the pockets open on the radially outer side as a result of centrifugal forces.
  • the turret 10 shown is used in conjunction with or as part of a packaging machine.
  • it is an example of the wrapping of elongated packs 11 in an outer wrapper 12 made of cellophane or plastic.
  • the pack 11 made of (thin) cardboard has been produced and filled in the area of other units of the packaging machine.
  • the content of the pack 11 is a solid, single object, namely a tube 13. This is accommodated with play in the pack 11, which is rectangular in cross section, so that the tube 13 can carry out relative movements within the pack 11.
  • tubular tabs 14 and 15 of the outer covering 12 are folded over one after the other against the associated radially outward-facing side surface 16 of the pack 11 and finally connected to one another by sealing. Furthermore, end folds can be carried out by folding members, which are not shown in the drawings.
  • the revolver 10 has a plurality of, in the present case six pockets 17. These are delimited in the circumferential direction of the turret 10 by side walls 18 and 19. The radially outer side of the pockets is open, so that the packs 11 can be inserted and pushed out of a (horizontally directed) pocket 17 by radial displacement.
  • the pockets 17 are further delimited by end walls 20 and 21 acting in the axial direction.
  • the radially inner end of the pockets 17 is formed by a bottom wall 22.
  • At least the side walls 18 and 19 can be moved relative to one another, in the sense of expanding or reducing the free cross section of the pockets 17.
  • the packs 11 can be inserted without problems in the region of an insertion station 23 into a horizontally directed pocket 17 , namely together with the U-shaped outer wrapping 12 surrounding the pack 11.
  • the packs 11 finished with respect to the outer wrapper 12 are pushed out again in the region of an ejection station 24 from a likewise horizontally oriented pocket 17 in the radial direction.
  • the clockwise movement of the revolver 10 takes place in the example shown in the counterclockwise direction, so that the (two) pockets 17 filled with packs 11 are directed upwards in the region between the insertion station 23 and the extension station 24.
  • a cross-sectional expansion of the pockets 17 by moving the side walls 18, 19 apart therefore does not result in the packs 11 being able to slide out of the pockets 17 pointing upwards.
  • the turret 10 consists of several, namely here of two partial turrets 25 and 26. These are each assigned one of the side walls 18 and 19. With relative adjustment the partial revolvers 25, 26 to one another are therefore also adjusted the side walls 18, 19 as part of one or the other partial revolvers 25, 26.
  • the partial revolvers 25 and 26 together form the revolver 10 and can be rotated as a unit.
  • the partial revolvers 25 and 26 can be rotated about a common axis.
  • the partial turret 26 is firmly connected to a drive shaft or a shaft journal 27.
  • the partial turret 25, however, is rotatably mounted on the shaft journal 27.
  • the partial revolvers 25 and 26 in the present case each consist of approximately radially directed revolver arms 28, 29 and 30, 31. At the ends of these arms 28, 29 and 30, 31, the side walls 18 and 19 are arranged, but not over the Full length of the revolver 10 continuously, but only as a short or narrow leg.
  • the packs 11 are therefore not covered over their entire length within a pocket 17 by side walls 18, 19 and the bottom wall 22, but only at the ends of the elongated packs 11.
  • Each pocket 17 accordingly consists of two end pockets for receiving the end regions of the pack 11 This is exposed in the middle area between arms 28 or 29 and 30 or 31.
  • the bottom wall 22 in the area of the turret arms 30 and 31 is dimensioned in the axial direction as well as the side walls 19 arranged on the same turret arms 30, 31.
  • the turret arms 28 and 29 assigned to the side walls 18 of a pocket 17 are fastened at an axial distance from one another in each case to a collar 32, 33 on the shaft journal 27 or at the end of the latter.
  • the partial turret 25 is mounted on the shaft journal 27 between the collars 32, 33, specifically with a continuous rotating sleeve 34.
  • the partial revolvers 25, 26 are adjustable relative to one another along an angle 36 by means of an actuating gear 35.
  • the Actuator 35 consists of a toggle lever arrangement with tabs 37 and 38. These are each articulated or pivotally connected to the sides of adjacent turret arms 28 on the one hand and 30 on the other.
  • the two tabs 37 and 38 are brought together in a common joint 39.
  • a feeler roller 40 is mounted in this.
  • the actuating gear 35 consisting of the tabs 37 and 38 is loaded in the direction of moving the side walls 18 and 19 of the pockets 17 together, that is to say in the direction of a reduction in the pocket cross section.
  • a tension spring 41 anchored to the turret 10 at the other end acts on the knee joint, namely in the common joint 39.
  • the tension spring 41 is only effective. This means that a force reducing the cross section of the pockets 17 is exerted on the partial revolvers 25, 26. The packs 11 are held in the pockets during this phase under clamping action.
  • the partial revolvers 25, 26 move relative to each other in the sense of a movement of the side walls 18, 19 apart.
  • the knee joint is acted upon against the force of the tension spring 41 in the sense of a reduction in the angular position between the tabs 37 and 38 .
  • An actuator acts on the feeler roller 40 of the tabs 37 and 38 in the sense of a radially outward movement.
  • the adjustment is effected by a cam 42 or 43.
  • the feeler roller 40 runs on the outer circumference of the cam plate 42 when the tabs 37, 38 are adjusted.
  • the cams 42, 43 are arranged concentrically with the turret 10, so that during the (cyclical) rotary movement of the turret 10 the feeler roller 40 can run outside the cam cams 44 on the cam 42 or in the cam groove 45 of the cam 43.
  • the cam plate 42 or 43 is rotatably mounted with a guide sleeve 46 on a fixed hollow pin 47. This in turn is mounted on a load-bearing element of the packaging machine, in the exemplary embodiment in FIG. 4 on a gear housing 48.
  • the shaft journal 27, the drive of which is located in the gear housing 48, passes through the hollow journal 46.
  • the crank disk 42 or 43 only executes a rotary movement along the angle 36 during the standstill phase of the turret 10, namely to adjust the turret arms 28 to 31 relative to one another.
  • This reciprocating rotary movement is generated by a push rod 49, which is articulated to the cam plate 42 or 43.
  • the push rod 49 is suitably driven, e.g. by a pressure medium cylinder (not shown).
  • the packs 11 are introduced via a horizontal pack track 50 into the pocket 17 facing them together with the outer wrapper 12.
  • the lower or rearward tubular flap 15 is folded over against the outer side surface 16 of the pack 11 by a folding finger 52.
  • the upper or front tubular tab 14 is also folded over against the side surface 16, specifically by means of a stationary, curved guide wall 53 which extends lengthways a pitch circle outside the range of motion of the turret 10 extends.
  • the overlapping tube tabs 14, 15 are sealed or pre-sealed by a first sealing member 54.
  • the tube tabs 14, 15 are sealed (final sealed) by a further, second sealing element 55.
  • the finished package 11 is pushed out of the horizontally lying pocket 17 into a likewise horizontally directed discharge path 56.
  • a pusher 57 comes into effect, which is arranged so that it can be moved back and forth between the turret arms 28 ... 31.
  • the movement phase of the folding turret is preferably 120 ° of a work cycle.
  • the entire standstill phase is 240 °.
  • the standstill phase is expediently divided into two partial phases of 120 ° each.
  • a first standstill phase of 120 ° the tubular flaps 14 and 15 are sealed by the sealing members 54 and 55.
  • the side walls 18, 19 of the pockets 17 remain in the closed or clamped position, that is to say in the narrow position.
  • the side walls 18, 19 are moved apart, that is to say the pockets 17 are opened.
  • the packs 11 can now be pushed in and out.
