Abstract
Description
Die Erfindung betrifft eine Anordnung zur automatischen Umreifung von Packstücken nach dem Oberbegriff des Anspruchs 1.The invention relates to an arrangement for automatic strapping of packages according to the preamble of claim 1.
Derartige Umreifungseinrichtungen sind in der Verpackungstechnik seit langem bekannt. Eine Anordnung mit den eingangs genannten Merkmalen ist beispielsweise der
Solche Maschinen dienen dem automatischen Umreifen von Packstücken in kurzer zeitlicher Aufeinanderfolge. Dabei wird das Umreifungsband aus thermoplastischem Kunststoff von einer auf einer Spule aufgewickelten Rolle, die drehbar auf einer Aufnahmevorrichtung der Maschine gelagert ist, zur Umwicklung eines Packstücks jeweils stückweise abgerollt. Sobald das Umreifungsband auf der Rolle aber zu Ende geht, muss die Maschine angehalten und die alte Rolle gegen eine neue mit genügend Material ausgewechselt werden. Danach kann dann der Umreifungsvorgang für weitere Packstücke fortgesetzt werden.Such machines are used for automatic strapping of packages in a short time sequence. In this case, 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.
Aufgabe der vorliegenden Erfindung ist es demgegenüber, eine Anordnung der eingangs genannten Art mit möglichst einfachen technischen Mitteln dahin gehend weiterzuentwickeln, dass in einem automatischen Umreifungsbetrieb der Anordnung Maschinenstillstandszeiten auch dann vermieden oder zumindest minimiert werden können, wenn das Umreifungsband auf der Spule zu Ende geht.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.
Erfindungsgemäß wird diese Aufgabe auf ebenso überraschend einfache wie wirkungsvolle Art durch die Merkmale des Anspruchs 1 gelöst.According to the invention this object is achieved in a surprisingly simple as well as effective way by the features of claim 1.
Sobald das Umreifungsband auf der ersten Spule zu Ende geht oder Abspulprobleme (z.B. Unterspulung) auftreten, kann schon das Umreifungsband auf der zweiten Spule bereitstehen und (manuell oder automatisch) durch Verschweißen an das Umreifungsband der ersten Spule angekoppelt werden, ohne dass Maschinenstillstandszeiten beim Wechsel der Bandentnahme auf die zweite Spule auftreten. Schon in einer Betriebsphase, in der mit dem Umreifungsmedium der ersten Spule gearbeitet wird, kann bereits die zweite Spule während des Maschinenlaufs auf die dafür vorgenommene Aufnahmevorrichtung gesetzt werden und dort in Bereitschaft zur Verfügung stehen.Once the strapping on the first coil comes to an end or Abspulprobleme (eg Unterspulung) occur, 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. Already in an operating phase, in which the strapping medium of the first bobbin is used, 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.
Besonders bevorzugt ist eine Ausführungsform der erfindungsgemäßen Anordnung, bei der die Andockvorrichtung eine Arretiereinrichtung zum passgenauen Zusammenführen der überlappenden Stücke der beiden Umreifungsbänder aufweist. Dies erleichtert den Spulenwechsel von einer leeren zu einer neuen vollen Spule erheblich und ermöglicht im Prinzip auch einen vollautomatischen Wechsel. Aber auch bei einer manuellen Bedienung stellt die Arretiereinrichtung eine große Hilfe dar.Particularly preferred is an embodiment of the arrangement according to the invention, in which 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.
Bei einer vorteilhaften Weiterbildung dieser Ausführungsform umfasst die Arretiereinrichtung eine Klemmvorrichtung zum Festhalten mindestens eines der beiden überlappenden Stücke, vorzugsweise des Rollenanfangs des Umreifungsbandes von der zweiten Spule, sodass ein Wegrutschen aus der Arretiereinrichtung vor dem Verschweißen der beiden Stücke sicher verhindert wird. Die Klemmvorrichtung kann auch zunächst nur den Rollenanfang des Umreifungsbandes von der zweiten Rolle aufnehmen, während diese in Bereitschaft steht, und erst beim eigentlichen Wechsel der Entnahme von der ersten auf die zweite Spule auch das entsprechende Überlappungsstück des Umreifungsbandes von der ersten Spule ergreifen. Je nach Anordnung kann aber eine Klemmung des überlappenden Bandstücks von der ersten Spule auch erst in der Schweißvorrichtung erfolgen.In an advantageous development of this embodiment, 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. Depending on the arrangement, however, a clamping of the overlapping piece of tape from the first coil can also take place only in the welding device.
Die Anordnung der Erfindung weist eine Detektionseinrichtung zum Erkennen der Ankunft des spulenseitigen Rollenendes des auf der ersten Spule aufgewickelten Umreifungsbandes auf. Damit wird auch ein automatischer Wechsel der Spulen bei Erreichen des Rollenendes ermöglicht. Zumindest kann eine derartige Detektionseinrichtung aber auch ein Signal für einen manuellen Wechsel auslösen.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.
In einer technisch einfach realisierbaren Lösung umfasst die Detektionseinrichtung einen optischen Sensor, insbesondere eine Lichtschranke.In a technically easily realizable solution, the detection device comprises an optical sensor, in particular a light barrier.
Gemäß der Erfindung ist ein Reflektor auf der Spulenoberfläche der ersten und zweiten Spule jeweils angeordnet, der von der auf die Spule gewickelten Rolle überdeckt wird, und der bei Erreichen des Rollenendes für den optischen Sensor sichtbar wird. So lässt sich die Detektion der Ankunft des Rollenendes mit äußerst einfachen und preisgünstigen Mitteln erreichen. Übrigens wird in der Regel der optische Sensor nicht bei Erreichen des eigentlichen Rollenendes, sondern bereits ein wenig vorher sichtbar, sodass genügend Zeit für einen Entnahmewechsel von der ersten auf die jeweils zweite Spule zur Verfügung steht.According to the invention, 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. Thus, the detection of the arrival of the role end can be achieved with extremely simple and inexpensive means. Incidentally, 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.
In einer Ausführungsform umfasst die Schweißvorrichtung mindestens einen erhitzbaren Schweißstempel. Diese Technologie ist preiswert und seit vielen Jahren auf dem Markt erhältlich.In one embodiment, the welding device comprises at least one heatable welding punch. This technology is inexpensive and has been available on the market for many years.
Zur Verbesserung der Handhabung ist eine weitere Ausführungsform der erfindungsgemäßen Anordnung von Vorteil, bei der die Arretiervorrichtung nach dem Zusammenführen und Andocken der überlappenden Stücke der beiden Umreifungsbänder aus dem Abwickelbereich der zweiten Spule wegschwenkbar ist. Dadurch wird einerseits Platz für den Einsatz der Schweißvorrichtung zum Verschweißen der Umreifungsbänder der beiden Spulen in ihrem Überlappungsbereich geschaffen, andererseits steht die Andockvorrichtung nach dem Verschweißen einer weiteren Entnahme von Umreifungsband nicht mehr im Wege.To improve handling, 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. As a result, on the one hand space is created for the use of the welding device for welding the strapping of the two coils in their overlapping area, on the other hand, the docking device is no longer in the way after welding another removal of strapping.
Ebenso ist es vorteilhaft, wenn die Andockvorrichtung auf einem Schlitten angeordnet ist, der relativ zu den Vorrichtungen für die drehbare Aufnahme der ersten und der zweiten Spule linear verfahrbar ist. Auch kann die Schweißvorrichtung gemeinsam mit der Andockvorrichtung verschwenkbar und/oder linear verfahrbar angeordnet sein.It is also advantageous if 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. Also, the welding device can be arranged together with the docking device pivotable and / or linearly movable.
Bei einer weiteren besonders bevorzugten Ausführungsform der erfindungsgemäßen Anordnung schließlich ist eine Schneidevorrichtung, insbesondere ein Messer, zum Abtrennen des Bandrestes des Umreifungsbandes von der ersten Spule nach dem Verschweißen mit dem Umreifungsband von der zweiten Spule vorgesehen. Nach dem Abschneiden des Bandrestes kann dann die Vorrichtung zur Aufnahme der ersten Spule weggeschwenkt oder weggefahren und die leere gegen eine neue, volle Spule ausgetauscht werden, die dann ihrerseits als "zweite" Spule wieder in Bereitschaft steht, bis die nunmehr als "erste" Spule dienende Spule durch die neue Spule ersetzt werden soll.In a further particularly preferred embodiment of the arrangement according to the invention, finally, a cutting device, in particular a knife, for separating the band remainder of the Strapping band provided by the first coil after welding to the strapping of the second coil. After cutting off the tape remnant, 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.
In den Rahmen der vorliegenden Erfindung fällt auch ein Verfahren zum Betrieb der oben beschriebenen erfindungsgemäßen Anordnung, bei dem der Überlappungsbereich der zu verschweißenden Teilstücke von Umreifungsband der beiden Spulen so gewählt wird, dass er den Rollenanfang des Umreifungsbandes der zweiten Spule und einen vom Rollenende des Umreifungsbandes der ersten Spule höchstens eine Wicklungslage entfernten Bandabschnitt, insbesondere das Rollenende des Umreifungsbandes der ersten Spule, umfasst. Hierdurch lässt sich ein "fliegender Wechsel" von einer gerade leer werdenden Spule auf eine neue volle Spule bewerkstelligen, was insbesondere einen automatischen Langzeitdauerbetrieb der Verpackungseinrichtung ermöglicht. Allerdings sollte nicht das allerletzte Bandende auf der Rolle der ersten Spule abgewartet werden, sondern der Wechsel sollte schon kurz vor Erreichen desselben eingeleitet werden, damit sichergestellt ist, dass zur Umreifung des nächsten anstehenden Packstücks auf jeden Fall genügend Umreifungsband von der entsprechenden Rolle zur Verfügung steht.In the context of the present invention also falls a method for operating the above-described arrangement according to the invention, in which 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. This makes it possible to accomplish a "flying change" from a coil becoming empty to a new full coil, which in particular enables automatic long-term operation of the packaging device. However, you should not wait for the very last end of the tape on the roll of the first reel, but the change should be initiated shortly before reaching the same, so that it is certain that for strapping the next upcoming package enough strapping from the appropriate role is available ,
Bei einer einfachen Variante des erfindungsgemäßen Verfahrens kann ein Wechsel der Entnahme von Umreifungsband zur Umreifung von Packstücken von der ersten zur zweiten Spule manuell erfolgen. Insbesondere das Beladen der Aufnahmevorrichtung mit der zweiten Spule wird in der Regel von Hand ausgeführt werden. Falls das Bandende der ersten Spule nicht mehr allzu weit entfernt ist, kann dann auch gleich ein manueller Wechsel zur Entnahme von der zweiten Spule eingeleitet werden.In a simple variant of the method according to the invention, a change of the removal of strapping for strapping packages from the first to the second coil can be done manually. In particular, 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.
Vorteilhaft ist aber auch eine Verfahrensvariante, bei der ein Wechsel der Entnahme von Umreifungsband zur Umreifung von Packstücken von der ersten zur zweiten Spule nach dem Erkennen der Ankunft des spulenseitigen Rollenendes des auf der ersten Spule aufgewickelten Umreifungsbandes automatisch erfolgt. Auf diese Weise kann die jeweils in Betrieb befindliche Bandrolle bis zu ihrem Ende voll ausgenutzt werden, ohne dass eine Bedienungsperson beim Wechsel bereitstehen muss.Also advantageous is a method variant in which a change of removal of strapping for strapping packages from the first to the second coil after detecting the arrival of the coil side roller end of the wound on the first coil strapping is done automatically. In this way, each in-service tape roll can be fully utilized to its end, without an operator must be available when changing.
Maschinenstillstandszeiten werden hiermit auf ein Minimum reduziert bzw. treten bei geeigneter Verfahrensgestaltung außerhalb der Wartungsperioden überhaupt nicht mehr auf. Eine operative Voraussetzung für diesen vollautomatischen Betrieb ist aber zumindest die oben erwähnte Detektionseinrichtung zum Erkennen der Ankunft des Rollenendes, damit der Wechsel automatisch ausgelöst werden kann. Unerlässlich ist dann auch eine Schneidevorrichtung, um die erste Spule körperlich vom weiteren Betrieb abzukoppeln, der mit der Bandentnahme von der zweiten Spule fortgesetzt wird. Schließlich sollte für den automatischen Verfahrensablauf auch noch die Andockvorrichtung und eventuell die Schweißvorrichtung aus dem Arbeitsbereich der Anordnung wegbewegt werden können.Machine downtimes are hereby reduced to a minimum or occur at a suitable process design outside the maintenance periods no longer on. However, 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. Finally, for the automatic procedure also the docking device and possibly the welding device should be moved away from the working area of the arrangement.
