Definitions

  • the invention relates to a device for feeding blanks to a packaging station, in particular from outer paper blanks for soft cigarette packs to cigarette-holding cells of a folding packer, with a conveying and gluing section conveying at a constant speed, at the end of which a conveying device is arranged, the conveying elements of which are intermittent at a conveying speed which can be driven between a maximum value corresponding to the speed of the conveying and gluing line and the current standstill in such a way that the cutting can be carried out at the time of the current standstill from a holding device of the packaging station which is adjacent to the delivery end of the device at this time.
  • Such a device is known from EP-C-0 133 511, in which a conveying and gluing section is provided which has rollers which can be driven at constant speed. This is followed by a suction belt which can be driven intermittently at a transport speed which varies between a maximum value corresponding to the speed of the rollers and the current standstill, such that the respective cut at the time of the current standstill is adjacent to the end of delivery at the time Suction belt located holder of the packaging station can be taken over, the last roll in the conveying direction of the conveying and gluing section having a flattened size such that the blank is released from the roll after detection by the suction belt.
  • the blanks can run due to the action of swirl, so that they are not positioned with sufficient accuracy in the packaging station.
  • the end position is not sufficiently precise when it comes to a standstill.
  • the object of the invention is to provide a device of the type mentioned at the outset, which makes it possible to cut the blanks in the packaging station practically without running and positioning precisely.
  • the conveying elements of the conveying device are formed by a pair of rollers which has at least one roller with a flattened portion such that the cut by means of the trailing axial edge (s) of the flattened portion (s) against a stop in a slightly curved position can be pressed, with the pair of rollers being followed by a guide path into which air outlet openings of an air supply device open, the air outlet openings opening into the guide path at an acute angle to the conveying direction of the blanks on the glued side of the blanks.
  • the air flow used here supports the transport of the blank and causes corresponding air cushions to form, through which the blank is guided without running up to a positioning stop, against which the blank is rolled by the pair of rollers in a slightly curved and therefore precise position to the object to be packed is pressed.
  • FIG. 1 shows schematically a partial side view of a device for feeding outer paper blanks for a soft cigarette pack to a revolver of a folding packer.
  • FIG. 2 shows a section through an air supply device for the device from FIG. 1.
  • blanks 1 are fed, for example, from a magazine and transported and glued further on a conveyor and gluing line, as is shown, for example, in EP-PS 0 133 511.
  • the conveying and gluing section ends in guides 2, 3 which are arranged partially opposite one another, in the area of which a pair of rolls 4 is arranged, the rolls 5 ', 5''of which with roller rings 6 on the areas of the blanks 1 which are not glued in the conveying and gluing section attack while the areas of the rolls 5 ', 5''lying between the roller rings 6 prevent contact with the glued areas of the blank 1 radially inward.
  • the rollers 5 ', 5' ' also have a flat 7 in the area of the roller rings 6 and are mounted mirror-symmetrically with respect to the flat 7.
  • the roller 5 'facing the non-glued side of the blank 1 protrudes with its roller rings 6 through recesses 8 in the guide 2 into the conveying path for the blanks 1.
  • the pair of rollers 4 can be driven intermittently at a transport speed which varies between a maximum value corresponding to that of the preceding part of the conveying and gluing section and momentary standstill, such that the blank 1 abuts a stop 9 radially inward from one at the moment of standstill with cell 11 of a revolver 12 of a folding packer already wrapped with inner paper 10 and filled with cigarettes.
  • the turret 12 is further provided, for example, with pressers 13 which can be pivoted via a cam control and which are adjacent to the respective cell 11 and which can be swiveled against the cell 11 after the blank 1 has been fed in, around the blank 1 against the wall of the cell 11 which runs in the direction of rotation of the turret 12 to press.
  • two folding thumbs 14, 15 are arranged radially on the outside and inside, so that the sections of the blanks 1 protruding radially inwards and outwards relative to the respective cell 11 are folded over by one cell division in the direction of the cell when the turret 12 is advanced .
  • the folding thumb 14 is connected to the guide 2, while the folding thumb 15 comprises a radial section 16 which forms the stop 9 and, with a guide plate 17, a gap 18 for receiving the leading end of the blank 1. On the inlet side, the gap 18 is widened in a funnel shape.
  • An air supply device 19 which is connected to an air supply line 20, is located between the roller 5 ′′ facing the glued side of the blank 1 and the outer circumference of the turret 12.
  • the air supply device 19 has guide webs 21 which extend in the transport direction of the blanks 1 in the areas of the blanks 1 which are not glued.
  • the guide webs 21 are each provided with a continuous groove 22 in the transport direction, an air outlet opening 23 opening into the grooves 22 in each case Channel 24 are connected to the air supply line 20.
  • the air outlet openings 23 expediently open into the conveying path for the blanks 1 at an acute angle of, for example, 15 to 30 ° in the transport direction.
  • the air flow generated by the air supply device 19 is expediently essentially laminar and supports the transport of the blank 1.
  • the respective blank 1 is gripped by the leading axial edges 25 of the flats 7 and transported by means of the roller rings 6 of the pair of rollers 4 forming the transporting roller gap.
  • the trailing axial edges 26 of the flats 7 engage with the blank 1 and preferably press it against the stop 9, so that the blank 1 bulges slightly relative to the adjacent cell wall.
  • the presser 13 then clamps the blank 1 against the cell 11, while turning the rollers 5 ', 5' 'increases the gap between the edges 26, so that when the revolver 12 is turned further, there is still a cell division section of the blank 1 located in the area between the rollers 5 ', 5' 'can be removed.
  • a cell belt or the like can also be used. use.
