Definitions

  • the invention relates to a method and a device for opening or spreading the flap / flaps of a cardboard or folding box already closed on the bottom.
  • the flaps which are still open, are in a position that does not hinder the packaging process. In particular, they must not stand in the way of the goods to be packaged and should therefore, if possible, be directed with their free edge away from the box, ie facing outwards.
  • suction devices or swivel arms are used in known devices of the type mentioned, with the aid of which the closure flaps are brought into the desired opening position.
  • the problem with these known devices is that they are format-dependent, ie they have to be set up for the respective box sizes and converted when the format is changed, which requires a longer machine stop.
  • the control and storage of the suction cups and swivel arms is complex and complicated and therefore prone to failure.
  • a device and a method for packaging bottles are also known, cardboard or folding boxes with opened closure flaps also being pushed over bottles to be packed.
  • the known device has two roller chains, which are arranged parallel to one another and laterally under the transport path of the folding boxes.
  • the two roller chains run faster than the transport path of the folding boxes and also serve as supports for bars.
  • these rods engage their front closure flap in the transport direction and fold them outward. This is done through form-fitting Attack of the bar on the closure flap and due to the higher running speed of the roller chains compared to the transport path for the folding boxes.
  • the invention has for its object to provide a method and a device for opening or spreading the flaps of the bottom already closed folding boxes, the method should be as simple and straightforward as possible and the device can work regardless of the format.
  • the invention provides that the folding box with the bottom pointing up and the flap hanging down is lowered from a floating position in such a way that the flap strikes a driver moving in the opening direction and is then moved by the latter in the opening direction.
  • the closure flap is loosely placed with its free edge on the driver moving in its opening direction.
  • the driver then pivots the closure flap in the opening direction corresponding to its direction of movement by frictional contact.
  • the folding box is lowered further until the closure flap or the closure flaps are spread out sufficiently.
  • the drivers can be endless belts, linearly movable sliding pieces or rollers.
  • the upper strand serves as a driver, the belts rotating with their respective upper strand in a direction away from each other. This direction also corresponds to the desired opening direction for the closure flaps.
  • Envelope packaging machine 1 which contains a stacking station 2 with a flap disc 3 for individually arriving envelopes.
  • Envelope stacks 4 are formed in the stacking station 2 and then moved on a work table 5 into a packaging station 6 in a manner not of interest here, in which cartons or folding boxes 7 closed on the bottom with hanging, sufficiently opened, i.e. with their free edges slightly flaps 8, 9 and 10, 11 pushed over the stack of envelopes 4 moved there in accordance with the illustration of the folding box 7a in FIG. 1.
  • the full folding boxes 7 are then turned in a manner not of interest here and finally closed, as is indicated in principle without further details in accordance with the dashed lines to the left of the packaging station 6 in FIG. 1.
  • the drivers 14 move , 15 away from each other and open or spread or open the flaps 8, 9 in the opening direction, the folding box 7 being continuously lowered until they not only with their flaps 8, 9 according to FIG. 3, but also with their Flaps 8, 9 carrying side walls 23, 24 flies on the carriers 14, 15.
  • the flaps 8, 9 are at a right angle to the side walls 23, 24 in a sufficient opening position so that they can then be transported further to the packaging station 6 after being lifted out of the flap opening station 13, where they can then be handled without problems can be pushed over a stack of envelopes 4 located there.
  • FIG. 2 The transport of a folding box 7 closed on the bottom to the flap opening station 13 and from there to the packaging station 6 (FIG. 2) takes place, for example, with the aid of a robot-like transport device 25 (FIG. 1), which uses one or more suction devices 26 to fold the boxes 7 on the bottom carries and can be moved, for example, along a rail 27 between the different stations both in the horizontal direction and in the vertical direction along one or more columns 28 (FIG. 1).
  • a robot-like transport device 25 FIG. 1
  • suction devices 26 to fold the boxes 7 on the bottom carries and can be moved, for example, along a rail 27 between the different stations both in the horizontal direction and in the vertical direction along one or more columns 28 (FIG. 1).
  • the closure flap opening station 13 comprises a worktop 29 or a table 29 with two recesses 31, 32 which are separated by a central web 30 and run parallel to one another.
  • the drivers 14 On the central web 30 are the drivers 14 which move away from one another during operation. 15 arranged.
  • these drivers 14, 15 are endless belts, as is also shown in detail in FIG. 7.
  • deflection rollers 33 and drive rollers 34 for each band-shaped driver 14, 15 are mounted in the table 29 and lie with their upper runs 35, 36 corresponding to the arrows in FIGS. 3 and 7 slightly above the plane of the surface 37 of the table 29.
  • the deflection rollers 33 and drive rollers 34 are arranged sunk into the table 29, the position of the adjacent rollers 33 being selected such that they are within the width B of a folding box 7 or the distance from the side walls 23, 24 and thus from the closure flaps thereof 8, 9 lie.
  • the two band-shaped carriers 14, 15 according to FIGS. 3, 4 and 7 are also aligned in one plane.
  • the length of the two band-shaped carriers 14, 15 is preferably different.
  • One band-shaped driver 14 can be relatively short, while the other band-shaped driver 15 can have any length. This makes it possible to fold boxes 7 of different sizes on and to process the same flap opening station 13, when one flap 8 is pivoted in the opening direction by the relatively short, band-shaped driver 14, while the other closure flap 9 attaches to the length of the band-shaped driver 15 at any point and then also opens there becomes.
  • the two recesses 31 and 32 also serve as opening aids for closure flaps, specifically for the long side flaps 10, 11.
  • the central web 30 points downwards or in the direction of removal accordingly 3 diverging side surfaces 38, 39. so that the side flaps 10, 11 open sufficiently for many applications if they slide with their free edges 40, 41 along the side surfaces 38, 39 of the central web 30 when the folding boxes 7 are lowered.
  • the result of such an opening or spreading process is shown in FIG. 4.
  • the endless belts serving as drivers 14, 15 are e.g. Rubber bands or rubber-like bands with a sufficient coefficient of friction and preferably lie with their upper run 35, 36 on the central web 30, which is provided with a recess 42 only in the area of the folding box 7 or the two deflecting rollers 33.
