Definitions

  • the invention relates to a device for transferring flat objects, in particular folding boxes, according to the preamble of claim 1.
  • Such transfer devices are arranged between a storage magazine for folding boxes and the conveying device of a cartoning machine and are used for removing a folding box from the magazine, opening and Transfer the same into a conveyor cup of the conveyor.
  • the suction cups of a suction head are arranged on its carrier in such a way that they grip a wall of the folding box in such a way that it has sufficient rigidity when it is opened or pressed on.
  • the arrangement of the suction cups of a suction head therefore depends on the format of the folding boxes to be treated, in particular on their width and length.
  • the transfer device according to the invention with the characterizing features of the invention has the advantage that, when changing the format, only individual suction cups are activated by adjustment to the working level or are deactivated by adjustment to the rest position, which can be carried out in a very short time.
  • the adjustment of suction cups to the rest position, in which the suction cups are physically set back from their working position, also has the advantage that the switched off suction cups do not come into contact with part of the folding boxes or with parts of the device.
  • FIG. 1 shows a folding box transfer device in a front view
  • FIG. 2 shows a part of the transfer device according to FIG. 1 in a front view in a different setting
  • FIG. 3 shows a suction head of the transfer device in longitudinal section
  • FIG. 4 shows a suction head in cross section in the plane IV-IV of the figure 3rd
  • the folding box transfer device is arranged between a magazine 11 for flat-lying folding boxes 1 and a conveyor device 14 of a cartoning machine equipped with driver pairs 12, 13. It has a three-armed rotary star 15, each with a suction head 20 at the end of each arm 16, 17, 18.
  • the rotary star 15 rotates on a circular path and is additionally rotated about its axis 19, so that its arms 16, 17, 18 are on one Move cycloid track.
  • the cycloidal path C which has four reversal points F, G, H, I, is shown in broken lines.
  • each suction head 20 has two cup-shaped suction cups 21, 22, which are open to the outside and whose suction level can be adjusted in a common gripping plane.
  • the suckers 21, 22 of each suction head 20 assume a working position (FIG. 1).
  • One of the two suction cups 21, 22 of each suction head 20, namely the one trailing in the conveying direction of the rotary star 15, is fastened on a threaded connector 23 which is seated in a radial bore 24 of each arm 16, 17, 18 of the rotary star 15 which forms a support and is secured with a lock nut 25.
  • each suction head 20 is seated on a connecting piece 27 which is displaceable in a second radial bore 28 of the arm 16, 17, 18 which is parallel to the first.
  • the radial bore 24 cuts a transverse bore 29 in each arm 16, 17, 18 and the radial bore 28 penetrates it.
  • the transverse bore 29 is connected to a vacuum source via a connecting piece 30, a line 31 and a control valve (not shown).
  • the second suction cup 22 of each suction head 20 is adjustable with the nozzle 27 in relation to the first suction cup 21 or to the working plane formed with the opening, in two positions, a working position in which its opening lies in the same gripping or working plane as that of the first sucker 21, and a rest position in which its opening is set back relative to the working plane (FIG. 2).
  • the displaceable nozzle 27 has two axially offset annular grooves 33, 34 in its circumference, one of which engages in the arm 16, 17, 18 a displaceable locking pin 35.
  • the locking pin 35 which penetrates the arm 16, 17, 18 transversely carries a stop head 36 at one end and a hat-shaped button 37 at the other, which holds the pin 35 in the locking position shown via a compression spring 38.
  • a constriction 39 in the pin 35 enters the area of the grooves 33, 34, so that the lock is released and the nozzle 27 with the suction cup 22 in the radial bore 28 can be axially displaced into another position.
  • the length of the nozzle 27 of the second suction cup 22 is selected so that in its working position, in which the opening of the suction cup 22 lies in the working plane, its free end 41 projects openly into the transverse bore 29, so that the suction cup 22 is activated by the negative pressure .
  • the free end 41 of the connecting piece 27 projects in its lower position, the rest position, into the part 40 of the radial bore 28 which projects beyond the transverse bore 29, so that its end face lies with the opening of the through bore 26 in the part 40 of the radial bore 28 which it closes and thereby the suction cup 22 is not connected to the vacuum shaft.
  • the connecting piece 27 In the area of its free, lower end 41, the connecting piece 27 carries a sealing ring 32 which ensures a complete seal in the projecting part 40 of the radial bore 28.
  • the movable suction cup 22 is brought into the radially outer position, the working position in which the opening of the suction cup 22 lies in the same working plane as that of the other fixed suction device 21 belonging to the same suction head 20. In this position, both suction devices 21 and 22 can be activated via the control valve with negative pressure.
  • the adjustable suction device 22 is moved into its rest position, in which its opening is set back from the working plane and in which the effect of the vacuum is interrupted. A spatial disturbance is also not possible in this rest position.
  • the nozzle 27 of the suction cup 22 is displaceable and lockable in two positions with a lock.
  • the connector 27 can also be provided with a thread and adjusted by screws to adjust its working and rest position in the radial bore.
  • the suction heads 20 of the rotary star 15 are brought one after the other to the lower end of the magazine 11, there take a provided, lying flat folding box 1 on a wall 2 delimited by folding grooves and pull this folding box out of the magazine 11 downwards.
  • push-on fingers 45 pivot against a wall 3, which is connected to the fixed wall 2 via a folding line 4, and press on the fixed folding box 1 before it is transferred between a pair of drivers 12, 13 of the conveying device 14 .
  • the transfer device only a single rotary star 15, each with a pair of suction cups 21, 22 on each arm 16, 17, 18, is shown.
  • the transfer device can also be equipped with two or more axially congruent rotating stars, so that the folding boxes are kept rigid over their entire length.
  • the suction cups of the additional rotating stars are designed and arranged as described above.
