Definitions

  • the invention relates to an arrangement for automatic strapping of packages according to the preamble of claim 1.
  • Such machines are used for automatic strapping of packages in a short time sequence.
  • the strapping band made of thermoplastic material is unrolled piece by piece from a wound on a spool roll, which is rotatably mounted on a receiving device of the machine, for wrapping a package. But once the strapping on the roll comes to an end, the machine must be stopped and the old roll replaced with a new one with enough material. Then then the strapping process can be continued for more packages.
  • EP-A1-0 662 438 discloses an apparatus including the features of the preamble of claim 1.
  • Object of the present invention is in contrast to further develop an arrangement of the type mentioned with the simplest technical means that in an automatic strapping operation of the arrangement machine downtime can be avoided or at least minimized even when the strapping on the coil comes to an end.
  • the strapping on the second coil ready and (manual or automatic) can be coupled by welding to the strapping of the first coil, without machine downtime when changing the Tape removal on the second coil occur.
  • Abspulprobleme eg Unterspulung
  • the second bobbin can already be placed on the pickup device made for this purpose during the machine run and be available there in readiness.
  • the docking device has a locking device for precisely matching merging of the overlapping pieces of the two strapping bands. This considerably facilitates the bobbin change from an empty to a new full bobbin and, in principle, also permits a fully automatic change. But even with a manual operation, the locking device is a great help.
  • the locking device comprises a clamping device for holding at least one of the two overlapping pieces, preferably the beginning of the roll of the strap from the second coil, so that slipping out of the locking device before welding the two pieces is reliably prevented.
  • the clamping device can also initially only record the beginning of the reel of the strap from the second role, while it is on standby, and only take the corresponding overlap piece of the strapping of the first coil at the actual change of removal from the first to the second coil.
  • a clamping of the overlapping piece of tape from the first coil can also take place only in the welding device.
  • the arrangement of the invention comprises a detection device for detecting the arrival of the coil side roller end of the wound on the first coil strapping. This also allows an automatic change of the coils upon reaching the roll end. However, at least such a detection device can also trigger a signal for a manual change.
  • the detection device comprises an optical sensor, in particular a light barrier.
  • a reflector is arranged on the coil surface of the first and second coil respectively, which is covered by the wound on the coil reel, and which is visible on reaching the roll end for the optical sensor.
  • the detection of the arrival of the role end can be achieved with extremely simple and inexpensive means.
  • the optical Sensor usually the optical Sensor not on reaching the actual role end, but already a little before visible, so that there is enough time for a removal change from the first to the second coil available.
  • the welding device comprises at least one heatable welding punch. This technology is inexpensive and has been available on the market for many years.
  • another embodiment of the arrangement according to the invention is advantageous, in which the locking device can be pivoted away from the unwinding region of the second coil after the merging and docking of the overlapping pieces of the two strapping bands.
  • the docking device is arranged on a carriage which is linearly movable relative to the devices for rotatably receiving the first and the second coil.
  • the welding device can be arranged together with the docking device pivotable and / or linearly movable.
  • a cutting device for separating the band remainder of the Strapping band provided by the first coil after welding to the strapping of the second coil.
  • the device for receiving the first reel can then be swung away or moved away and the blank can be exchanged for a new, full reel, which in turn stands in readiness as a "second" reel until the reel is now called the "first" reel Serving coil to be replaced by the new coil.
  • the overlapping region of the parts to be welded strapping of the two coils is selected so that it is the beginning of the reel of the second spool and one of the roll end of the strapping the first coil at most one winding layer removed band portion, in particular the roll end of the strapping band of the first coil comprises.
  • a change of the removal of strapping for strapping packages from the first to the second coil can be done manually.
  • the loading of the receiving device with the second coil will usually be carried out by hand. If the end of the tape of the first coil is no longer too far away, then a manual change to the removal of the second coil can then be initiated.
  • Machine downtimes are hereby reduced to a minimum or occur at a suitable process design outside the maintenance periods no longer on.
  • an operative prerequisite for this fully automatic operation is at least the above-mentioned detection device for detecting the arrival of the roll end, so that the change can be triggered automatically.
  • a cutting device is then also essential in order to physically decouple the first coil from the further operation, which is continued with the tape removal from the second coil.
  • the docking device and possibly the welding device should be moved away from the working area of the arrangement.
  • FIGURE shows a schematic representation of essential functional components of an embodiment of the arrangement according to the invention.

  • the coil itself is omitted for clarity in the figure.
  • the device 10 for coupling a on a second coil (which is also not shown) rolled strapping to the strapping of the first coil.
  • the device 10 comprises a second device 2 for rotatably receiving the second coil, a docking device 3 for overlapping each of a portion of the strapping of the second coil and a welding device 4 for welding the strapping of the two coils in its overlapping region.
  • the docking device 3 includes, inter alia, a locking device 5 for precisely matching merging of the overlapping pieces of strapping of the two coils.
  • the locking device 5 in turn comprises a clamping device for holding at least one of the two overlapping pieces.
  • a cutting device 7 is provided, which comprises a knife for separating the band remainder of the strapping band from the first spool after welding to the strapping band from the second spool.

Abstract

L'invention concerne un système permettant de cercler des colis de manière automatique, dans chaque cas avec une bande de cerclage en matière plastique. La bande de cerclage est enroulée sous forme de rouleau sur une première bobine. Il est prévu un premier dispositif (1) pour loger la première bobine de manière rotative, première bobine d'où la bande de cerclage est dévidée à l'unité pour entourer un colis. Ledit système se caractérise en ce qu'il est prévu un dispositif (10) pour raccorder une bande de cerclage enroulée sur une seconde bobine, à la bande de cerclage de la première bobine. Ledit dispositif (10) comprend un second dispositif (2) pour loger la seconde bobine de manière rotative, un dispositif d'accouplement (3) permettant le chevauchement, dans chaque cas, d'une section partielle de la bande de cerclage de la première bobine et d'une section terminale libre de la bande de cerclage de la seconde bobine, ainsi qu'un dispositif de soudage (4) pour souder les bandes de cerclage des deux bobines dans leur zone de chevauchement. Ce système permet d'effectuer, sans grande complexité technique, des changements de matériaux de cerclage, sans temps d'arrêt des machines ou avec des temps d'arrêt minimisés.
