Definitions

  • the invention relates to a transfer device for rectangular objects, in particular objects to be wrapped in cling film, preferably cigarette packets, with a conveyor for the successive delivery of the objects and a device for taking the delivered objects up to a straight slide for pushing the objects to a subsequent packaging station, in particular one Foil wrapping device (see for example DE-A-2 642 474).
  • the object of the invention is to provide a device of the type mentioned, which enables very short cycle times and nevertheless a gentle treatment of the objects.
  • entrainment members are provided for the flying transfer of the objects to a pocket of the device for carrying the objects, the pocket being coupled to a drive in such a way that it runs through a closed path, with a portion of its circulation in the direction of extension of the slider and the sequence of movements of the pocket and the slider are synchronized such that the slider has only a low relative speed when entering the pocket during its orbital movement in the direction of extension of the slider.
  • the cuboid objects are moved synchronously in the transport direction by the take-away device, which comprises the pocket, and the slide, and each is transferred on the fly, so that they never come to a standstill, so that very short cycle times are made possible.
  • the bag also has the task of making the impact speed of the slider as small as possible and of keeping the object in motion, so that no unnecessary stops are required, but a continuous transfer takes place.
  • the bag makes it possible to save time for the forward and backward movements necessary for the transfers from the conveyor or to the subsequent packaging station.
  • the movement of the bag in the direction in front of the slide relieves the pressure of a driving element for transferring the object from the conveyor into the pocket, so that there is practically no relative movement between the object and the driving element associated with friction.
  • the latter After transferring the objects into the pocket, the latter is preferably moved into a position adjacent to a slide via a parallelogram drive and the object moved through the pocket in the direction of movement of the slide is conveyed further by the slide, the relative speed between the moment the slide hits the object can be brought to a low value, ie almost to zero, so that the articles are treated extremely gently.
  • the actual speed of the object and the pusher at the moment of impact is the speed of the bag in relation to the machine frame of the packaging machine. After the slider strikes the object, the slider is correspondingly accelerated to push the object out of the pocket into a subsequent receiving member.
  • the object can be inserted into the bag using a drive wheel.
  • cigarette packets 1 to be provided with a cover made of transparent film are fed via a conveyor, not shown.
  • the cigarette packs 1 are conveyed one against the other with a narrow side downwards and pressed in the direction of the driving wheel 3, so that after taking a cigarette pack 1 with a driving nose 4, the following cigarette pack 1 comes into contact with the driving wheel 3.
  • the diameter of the driving wheel 3 between two driving lugs 4 decreases continuously by the radial length of the driving lug 4, so that the pack of cigarettes 1 coming into contact continuously comes into the recess in front of the respective driving lug 4.
  • the driving wheel 3 pushes the respectively received cigarette packet 1 into a pocket 6.
  • the pocket 6 is connected to a parallelogram drive 7, which comprises two rods 8, which are each connected to one side of the pocket 6.
  • the rods 8 are hinged at the other end to a crank 9 which is seated on a shaft 10.
  • a link 11 is articulated on each rod 8, the other end of which is rotatably mounted about a fixed axis 11a.
  • the crank 9 and the link 11 have the same length, the longitudinal axes of the rods 8 always running parallel to the connecting line of the center points of the shaft 10 and the axes 11a.
  • the pocket 6 is moved by the parallelogram drive 7 in a movement consisting of a vertical and a horizontal component out of the path of the driving wheel 3 in the conveying direction up to a slide guide 13 so that the carried cigarette packet 1 comes to rest against a resilient upper stop 12.
  • the driving wheel 3 by continuing to turn the driving wheel 3, the cigarette packet 1 is pushed further and further into the pocket 6 until it is completely accommodated in the pocket 6 and the corresponding driving nose 4 dips away.
  • the slide guide 13 receives a slide 14 which is displaceable via a crank 15 in order to push the cigarette packet 1 upon alignment of the pocket 6 with the slide guide 13 and a feed channel through the latter into a cell of a revolver, not shown, during the passage of the feed channel, a corresponding section made of transparent film, which is held ready to extend across the conveyor path of the slide 14, is taken along.
  • the movements of pocket 6 and slider 14 are coordinated such that the slider 14 has a speed almost equal to that of the cigarette packet 1 when it hits the cigarette packet 1 moved from the bag 6 in the direction of the feed channel, which speed then increases to the cigarette packet 1 slide out of pocket 6. In this way, the cigarette packets 1 are handled extremely gently despite the high packaging speeds.
  • the pocket 6 has bottom-side slot-shaped recesses 6 '(Fig. 2) through which the driver lugs 4 dive away when transferring the cigarette packet 1, while the pocket 6 on the top side only has edge strips 6', so that the slide 14 is unhindered by the movement of the pocket 6 drive through and emerge from the pocket 6.
  • the cigarette packet 1 Due to the "flying transfers", the cigarette packet 1 remains completely in the flow and does not suffer a standstill which impairs the conveying speed.
  • the drive takes place via a common drive shaft 17, with which a gear wheel 18 connected to the shaft 2 is in meshing engagement. Furthermore, there are two cam disks 19, 20 arranged at a distance from one another on the drive shaft 17, while the shaft 10 is connected to a lever 21 which carries two rollers 22 which engage with the cam disks 19 and 20, via which the crank 9 passes - And pivoted here and thus the pocket 6 is moved synchronized with the movement of the driving wheel 3.
  • the revolver in the cells of which the cigarette packs 1 are inserted for wrapping in the section made of transparent film, is also driven by the drive shaft 17 via corresponding gear elements step by step in accordance with the cell division of the revolver in synchronization with the shaft 2.
  • the driving wheel 3 can, as can be seen from Fig. 2, have a circumferential radial groove 24, so that the driving wheel 3 consists essentially of two axially spaced and connected via a hub part wheel parts.
  • the side parts of the pocket 6 each have a longitudinally extending groove 25 on the outside, while the rods 8 have corresponding projections 26 which are received by the grooves 25, so that changing the pocket 6 does not require any complex adjustment.
  • the conveyor for delivering the cigarette packs 1 comprises a belt 28 provided with driving lugs 4 and guided around corresponding deflection wheels 27, the Drive lugs 4 push the cigarette packs 1 into the pocket 6 one after the other.
  • the pocket-side deflection wheel 27 can also be designed like the driving wheel 3 and can be provided with driving lugs 4 instead of the belt 28.
  • a multi-joint drive can also be used.
