Definitions

  • the invention relates to a cross-sealing device for a tubular bag packaging machine with at least one pair of cross-sealing jaws, which can be placed on a plastic tube that may be moved in the direction of its longitudinal axis, in this case transverse to its longitudinal axis by a transverse sealing seam in each case Dividing packaging, and with at least one pair of scraper bars leading the cross seal jaws, arranged symmetrically to one another and parallel to the cross seal seam and symmetrically moved with respect to one another and along the sealing area, which clamps the plastic tube between them inside and along at least part of the sealing area, Paint over at least one area of the plastic tube provided for the transverse sealing seam in such a way that the packaged goods are stripped from this area into the tubular bag packaging to be sealed.
  • a cross seal device of this type is already known from German Offenlegungsschrift DE 37 32 033 A1. It ensures that the area of the later transverse sealing seam is kept free of packaging material until the sealing has taken place.
  • the movement of the scraper bars is included coupled to that of the cross seal jaws in order to avoid failed attempts by such forced guidance. It must namely be ensured that the stripping bars are already below the cross seal jaws when they produce the sealing seam, and they have to move faster along the sealing area than the plastic tube in order to remove any packaging material present in the area of the subsequent sealing seam to intervene the previous, actual packaging volume.
  • the scraper bars are connected to the cross seal jaws by means of pivoted levers and, like the cross seal jaws, are guided by a cam control.
  • the invention is therefore based on the object of designing a cross-sealing device of the type specified in the introduction in such a way that highly sensitive and expensive mechanical positive guides for the scraper bars are no longer required and the components used are low-wear and easily replaceable without extensive set-up work, and that they are user-friendly the system can be easily adapted to different packaging tasks.
  • an endless, flexible drive belt is provided on both sides and symmetrically to the sealing area, that the stripping rods are attached in pairs to the two drive belts, that the drive belts continue to be from a common one Drive are driven synchronously via a drive roller and that a control device is also provided for this drive, which controls the movement of the stripping bars independently of the movements of the plastic tube and the cross-sealing jaws, the drive belts preferably each being formed by an endlessly closed toothed belt will.
  • a fixed mechanical assignment of the movement of the stripping bars to that of the cross seal jaws is no longer necessary in the cross seal device according to the invention.
  • the belt drive provided instead has the advantage that the components used are not subject to constant mechanical wear and require no expensive special manufacture, but can be put together from commercially available parts and easily replaced by replacing them.
  • the special control of the scraper bars allows the cross-sealing device to be adapted to very different packaging tasks, for example taking into account the respective packaged goods and the type and size of the plastic tube used and the tubular bag packaging.
  • An arrangement of the drive belt that is spatially adapted to the movement of the stripping bars occurs when the preferably spur-toothed inside of the drive belt is guided over one of each of the drive rollers and a plurality of first tensioning rollers, the drive roller being expediently provided at the end of the sealing area, so that the stripping bars are pulled
  • the belt of the drive belt is always located when you cover the plastic hose.
  • the drive belts which are arranged symmetrically in space with respect to the sealing area, can be driven easily synchronously in such a way that the drive torque is introduced into the drive rollers by means of a common belt drive connected to the drive, it being favorable if the slippage of the belt drive on the drive rollers is minimized by at least one second tension roller, it is best that the second tension roller (s) is (are) arranged so that the wrap angle on the two drive rollers is almost the same.
  • a servo motor is provided for the drive, which is speed-controlled by a position controller which regulates the time-dependent position of the stripping bars, which position can be measured in a simple manner by a proximity switch, for example via a servo amplifier.
  • a position controller which regulates the time-dependent position of the stripping bars, which position can be measured in a simple manner by a proximity switch, for example via a servo amplifier.
  • Such position controls can be carried out very precisely and without inertia, especially with electronic measuring and control means, so that the functional separation of the drives from cross-sealing jaws and stripping bars has no disadvantageous consequences for their spatial assignment.
  • a considerable improvement of the state of the art is also the possibility created by the invention of changing the setpoints of such a position control, for which purpose it is expedient if the position controller has an incremental encoder for the speed control of the servo motor.
  • An adjustment can be carried out in a user-friendly manner if a display is provided on the position controller as a setpoint setting for determining the stripping path covered by the stripping rods that clamp the plastic tube and strip the packaging material into the tubular pouch packaging within the sealing area.
  • the sealing area is arranged vertically, because the packaged goods are subjected to gravity and cannot flow back into the area of the sealing seam when they have already been stripped off.
  • an upper stripping path piece can be set, which is just below that on the transverse sealing seam adjacent cross seal jaws ends, but it is instead or additionally also possible that a lower stripping path piece is adjustable, which begins just below the cross seal jaws resting on the cross seal seam. Both stripping path pieces together form the stripping path, which can be modified in this way.
  • a transverse sealing device consists of two elastic and arranged mirror-symmetrically on a rectilinear sealing area 1
  • Endless drive belts 2 which are each guided via associated first tensioning rollers 21 and (FIG. 4) are each driven by a drive roller 22.
  • a plastic tube 3 is conveyed vertically downward through the sealing area 1 in the direction specified by a directional arrow 31, packaging material 30 being introduced into the plastic tube 3 in a known manner and not further explained in the drawing.
  • FIG. 1 two mutually movable cross seal jaws 4 are indicated, which are shown in somewhat greater detail in Fig. 4.
  • the cross seal jaws 4 are each provided with two sealing surfaces 41, which produce two parallel cross seal seams on the squeezed plastic tube 3.
  • a cutting device is provided between the sealing surfaces 41, which is omitted in the drawing for the sake of clarity and serves to separate the tubular bag packages 32 from the plastic tube 3.
  • the details are customary.
  • the cross-sealing jaws 4 are synchronized with one another, but are driven independently of the drive belts 2 and only lie temporarily against the plastic tube 3 within the sealing area 1 for the purpose of sealing and separating the tubular bag packaging 32, schematically in FIG. 1 a dotted representation of the cross-seal jaws 4 which have already been removed from the area of the plastic tube 3 is indicated.
  • the way of driving the cross seal jaws 4 is not related to the invention; an example can be found above Publication can be taken.
  • Stripping rods 23 are attached in pairs to the drive belts 2 in such a way that the mirror symmetry of the drive belts 2 is maintained.
  • Fig. 1 two pairs, in Fig. 4 four pairs of scraper strips 23 can be seen, suggesting in this way that the paired number of scraper bars 23 is relatively variable and can be adapted to the respective packaging tasks.
  • a position controller 5 is used as the central control unit for the control of the drive belts 2 of the transverse sealing device according to the invention, which controls the operation of the drive belts 2 as a function of a setpoint value adjustment that can be made on a display 51 and of the actual value for the position of the stripping bars 23 controls, which is measured by a proximity switch 52 (Fig. 4).
  • the input variables obtained in this way are processed electronically in a suitable manner; the output variables dependent thereon for regulating the position, speed and acceleration of the stripping bars 23 are - amplified in a servo amplifier 53 - fed to a servo motor 61 which drives the drive rollers 22 via a gear 62 (FIG. 4).
  • a position control can also take place if the position controller 5 is equipped with an incremental encoder for the speed of the servo motor 61.
  • the stripping path 10 means the distance within the sealing area 1 that is required for complete removal of packaging material 30 from the area of the plastic tube 3 intended for the sealing and within which the stripping bars 32 along the slower moving plastic tube 3, this jammed between them, to be moved.
  • Fig. 3 shows that it is possible to set an "upper” stripping path 10a, which ends just below the position which the cross seal jaws 4 assume during the production of the cross seal seam.
  • a "lower” stripping path 10b begins at this point and extends in the direction of the arrow 31.
  • the entire stripping path 10 as well as the stripping path pieces 10a and 10b can be changed within limit values fixed to the device.
  • a drive 6, which consists essentially of the servo motor 61 and the gear 62, drives the drive rollers 22. It is provided with a belt drive 64 according to FIG. 4, second tensioning rollers 63 ensuring that a sufficient wrap angle on the drive rollers 22 is provided slip-free, synchronous drive guaranteed.
  • One fixed piece on the transverse sealing device 7 is underlaid on the drawn run of the respective drive belt 2, so that it cannot avoid when the stripping rods 23 on the plastic hose 3 are effective.
