Definitions

  • the invention relates to a device for stacking flat objects according to the preamble of patent claim 1.
  • the object of the invention is therefore to provide a device according to the preamble of claim 1, with which objects made of lobed or light or wrinkled material can also be stacked.
  • objects made of lobed or light or creasing material can be placed straight on top of one another for the purpose of stacking them, since these are stretched out and held by the blown air stream above the stacking point and are braked by the suction air nozzles and below which Blown air flow swept area are moved so that after their release they can fall gently and essentially unaffected by blown air and kinetic energy on the stacking site or the stack being formed.
  • DE-A-2040549 discloses a stacking device for flat objects which are sucked in at their rear ends by a roller provided with suction openings during their stacking.
  • the flat objects to be stacked are placed upright on their leading edges, one after the other, by a suction belt conveyor on a lower edge, the suction roller being provided with suction nozzles only over half of its circumference and with blowing air nozzles over the other half.
  • the roller detects the flat objects conveyed in the vertical direction with its suction nozzles in its rear end region and thereby pulls them off the suction belt conveyor. Since the roller rotates, the blowing air nozzles blow air into the gap between the removed flat object and the suction belt conveyor so that it is completely removed from the suction belt.
  • the known device is relatively complex, it is not suitable for stacking flat objects made of lobed, light and wrinkled material, since they cannot be stacked upright.
  • the lower deflection rollers are expediently rotatably mounted on a shaft which is provided with radial suction air nozzles located between the deflection rollers and which are connected to a suction air duct running axially in the shaft.
  • the mouths of the suction air nozzles are located approximately in a tangential plane of the deflecting rollers, so that they can suck in the workpieces in the region of their rear edges when passing through the conveying planes.
  • a control is provided which delivers the workpieces to the double belt conveyor in such a way that the passage of the suction nozzles through the conveyor plane coincides with the passage of the rear edge region of the objects.
  • the speed of the suction air nozzles is therefore matched to the cycle of the workpieces.
  • Several rows of suction air nozzles can also be offset at an angular distance from one another.
  • a tubular film web 3 made of lobed, light thermoplastic material is advanced by feed rollers 1, 2 and fed to a cross-welding separation station 4, 5, which is arranged behind the feed rollers 1, 2 in the conveying direction.
  • the cross welding separating station consists of a separating jaw 4 that can be moved up and down and a welding roller 5 assigned to it.
  • the individual workpieces separated from the separating seam jaw are introduced between an upper 6 and a lower conveyor belt 7, the deflecting roller 8 of the upper belt 6 adjacent to the separating seam jaw 4 being designed as a tipper roller in order to pull off any workpieces adhering to the separating seam jaw.
  • Both the upper and the lower conveyor belt 6, 7 each consist of a plurality of individual belts arranged next to one another at a distance.
  • the two front deflection rollers 9 and 10 of the conveyor belts 6 in the conveying direction and 7 are provided with a plurality of annular grooves, through which blown air nozzles 11 and 12 are passed and the blown air is directed so that the individual workpieces ejected from belts 6 and 7 are discharged by the blown air stream to such an extent that they are free on a lower discharge belt 13 can fall down.
  • the lower conveyor belt 13 is assigned a stop 14 which limits the path of the workpieces in the horizontal direction and which can be pulled up by a piston-cylinder unit 15 if a loot stack 16 is formed which is to be transported away from the belt 13.
  • the ends of the individual workpieces 17 are gripped by suction air nozzles 18 shortly before exiting the pair of belts 6, 7, braked and by rotating the nozzles in Moved clockwise down towards the stack 16. As soon as a workpiece 17 has reached the position shown in broken lines in FIG. 1, the suction air is switched off and the workpiece can then fall freely onto the stack 16.
  • the suction air is controlled as follows:
  • the axis 19 of the deflection roller 10 of the lower conveyor belt has a through hole 20.
  • the suction air nozzles 18 are screwed into the shaft 19, namely that they are connected to the bore 20.
  • a rotary valve 21 is placed on one end of the shaft 19 and has an opening angle of approximately 80 °.
  • the shaft 19 itself makes one revolution per bag.
  • several freely rotating belt rollers 22 are placed on the shaft 19, over which the belts of the conveyor belt 7 run.
  • the belt 7 is driven via the deflection roller adjacent in the welding roller 5, while the drive of the shaft 19 is achieved via a cam plate 23, which is connected to the shaft 19, for example, via a chain or a V-belt.
  • Fig. 1 shows that on the cam 23, a roller 24 runs, which is attached to a lever 25 which in turn is pulled down by a spring 26, so that the roller 24 is constantly pressed against the cam 23.
  • the lever 25, which is mounted at 27, carries an angled holder 28, the free leg of which, depending on the position of the cam plate 23, projects above or releases the stack 16 to be formed.
  • the lever 28 thus serves as a so-called wind deflector and is designed in such a way that the entire end face of the stack to be formed, which faces the blown air nozzles 11 and 12, is completely covered.
  • blowing air nozzles 11 protrude rearward from the pair of belts 6 and 7 in the transport direction, while the lower blowing air nozzles 12 are shorter so as not to obstruct the path of the workpieces 17.

Claims (4)

1. Dispositif pour empiler des articles plats (17) tels que sachets, sections tubulaires ou articles semblables, de préférence en matière flasque et/ou légère et froissante comprenant une double bande transporteuse (6, 7) se composant de différentes bandes tournant en parallèle à une certaine distance, entre lesquelles des buses soufflant de l'air (11, 12) sont disposées à proximité des poulies de renvoi (9, 10) avant par rapport au sens de l'avancement, buses qui sont disposées dans le sens de l'avancement et qui servent à décharger les articles (17), comprenant également une table d'empilement ou une bande transporteuse de piles (13) et une butée mobile avant (14) qui détermine le bord avant de la pile (16), butée à laquelle arrivent les articles (17) déchargés l'un après l'autre, caractérisé par le fait que des buses aspirant de l'air (18) sont prévues qui tournent autour de l'axe des poulies de renvoi (10) inférieures et aspirent les extrémités arrière des articles (17) avant qu'ils ne quittent la double bande transporteuse (6, 7) et qui livrent lesdits articles après un mouvement de basculement dans la zone au-dessous des buses soufflant de l'air (11, 12).
