Definitions

  • the invention relates to a device for producing tubular bag packs according to the preamble of the main claim.
  • a device of this type which has become known from DE-A-2134475
  • two endless conveyor belts of the pulling device are driven intermittently via a chain drive, the chain of which wraps around the drive wheels for the conveyor belts in a relatively small arc, so that the individual sections of the chain run at an angle to one another Straight lines.
  • This drive allows only a narrowly limited adjustment of the two conveyor belts against each other together with their drive wheels for format change. It is therefore desirable for the conveying means of the pulling device to have a traction mechanism drive which allows the distance between the conveying means to be adjusted in a large range in a simple manner.
  • the device according to the invention with the characterizing features of the main claim has the advantage that a continuous adjustment of the distance between the conveying means can be carried out in a wide range without intervention in their drive. In the event of mutual adjustment, the parallel sections of the traction mechanism drive automatically compensate for their change in length.
  • a packaging material web 1 running from a supply roll (not shown) is guided over deflecting rollers 10, 11 and a shaping shoulder 12, which forms it around a shaping and filling tube 13 to form a tube 2.
  • a longitudinal sealing jaw 14 welds the two overlapping edges to form a longitudinal seam 3 and a pair of transverse sealing jaws 15, 16 divides the tube 2 into individual pouch packs 4 after filling a portion of the filling material through the forming and filling tube 13.
  • a pair of conveyor belts 20, 21 is arranged to advance the hose 2 by one bag length each. The opposite strands of the two conveyor belts 20, 21 rest on the hose 2 and pull it down by friction.
  • the belts 20, 21 are preferably perforated and their tensile strands run in front of a vacuum chamber, so that the frictional connection between the hose and the conveyor belt is increased by the pressure difference generated.
  • the carriers 26, 27 are displaceable against one another transversely to the conveying direction of the hose 2 on two straight rods 28, 29 in the machine frame 30.
  • the brackets 26, 27 can each be clamped in a specific position by means of locking screws 31, 32.
  • the lower deflection roller 23 of one conveyor belt 20 is connected directly to a drive wheel 34 via a shaft 33 mounted in the carrier 26 and the deflection roller 25 of the other conveyor belt 21 is connected to another drive wheel 35 via a gear train.
  • the gear train serving to reverse the direction of rotation has two intermeshing, equal-sized gears 36, 37, of which one 36 is connected via a shaft 38 to the deflection roller 25 and the other 37 via a shaft 39 to the second drive wheel 35, the shafts 38 and 39 are rotatably mounted in the carrier 27.
  • the axes of rotation of the two drive wheels 34, 35 lie in a plane which is parallel to the direction of displacement of the carriers 26, 27 or the longitudinal axes of the rods 28, 29.
  • the two toothed drive wheels 34, 35 are wrapped by an endless toothed belt 40 on half of their circumference, which is guided over two deflection rollers 41, 42, a deflection wheel 43 and a drive wheel 44.
  • the toothed belt 40 touches the drive wheels 34, 35, the drive wheel 44 and the deflection wheel 43 with its inside, whereas the deflection rollers 41, 42 touch with its outside.
  • the two deflection rollers 41, 42 have the same diameter and are mounted on the brackets 20, 21 above and offset from the drive wheels 34, 35 and rotatably mounted, their axes of rotation lying in a plane that is parallel to the plane of the axes of rotation of the drive wheels 34, 35 is.
  • the deflection wheel 43 and the drive wheel 44 which are mounted in the machine frame 30, have the same diameter and can be rotated about axes which lie in a top plane parallel to the two planes mentioned above.
  • the three planes mentioned, in which the axes of rotation of the drive wheels 34, 35, the deflection rollers 41, 42 and the deflection and drive wheel 43, 44 lie, are each at such a distance from one another that the free distances of the toothed belt 40 also run in parallel planes . These are in particular the route 45 between the two drive wheels 34, 35, the distance 46 between the deflection wheel 43 and the deflection roller 41 on a support 26 and the distance 47 between the deflection roller 42 on the other support 27 and the drive wheel 44.
  • This parallelism of the distances 45-47 of the toothed belt 40 results in Moving the carrier 26, 27 to adjust the distance between the conveyor belts 20, 21 no increased tension and also no sag of the toothed belt 40.
  • a moving apart and moving together of the conveyor belts 20, 21 to pull the hose 2 or to change the format is therefore after loosening the locking screws 31, 32 can be carried out quickly and easily.
  • the toothed belt 40 which transmits the drive to the drive wheels 34, 35 for the conveyor belts 20, 21, is driven by the drive wheel 44, which is driven intermittently by an electric motor 49 via a belt drive 48.
  • the electric motor 49 is in each case switched on and off by a suitable control device as a function of the print mark spacing on the packaging material web 1 or on a measuring wheel 50 resting on the packaging material web 1.
