Description

Die Erfindung betrifft ein Verfahren zum (halbautomatischen) Verbinden von Materialbahnen aus Verpackungsmaterial, nämlich einer ablaufenden Bahn - Ablaufbahn - mit einer neuen Bahn - Neubahn - mittels Tape. Weiterhin betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for the (semi-automatic) joining of material webs of packaging material, namely an expiring web - runway - with a new train - Neubahn - by means of tape. Furthermore, the invention relates to a device for carrying out the method.

Die fortlaufenden Versorgung von Verpackungsmaschinen mit bahnförmigem Verpackungsmaterial ist bei zunehmender Leistung der Verpackungsmaschinen und dadurch bedingtem hohen Materialverbrauch ein besonderes Problem. Es geht darum, eine neue Materialbahn an eine ablaufende Materialbahn bei Verbrauch einer zugeordneten Bobine anzuschließen. Bekannt sind manuelle Verbindungsaggregate - Splice-Vorrichtungen -, aber auch vollautomatisch arbeitende Einrichtungen. Letztere sind apparativ sehr aufwendig und darüber hinaus störanfällig. Derartige Vorrichtungen wurden bereits in US 4,415,127 und GB 859 386 offenbart.The continuous supply of packaging machines with web-shaped packaging material is a particular problem with increasing performance of the packaging machines and consequent high material consumption. The idea is to connect a new material web to an outgoing material web while consuming an associated bobbin. Are known manual connection units - Splice devices - but also fully automatic operating devices. The latter are very complex in terms of apparatus and moreover prone to failure. Such devices have already been in US 4,415,127 and GB 859,386 disclosed.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen für eine rationelle Verbindung von Materialbahnen vorzuschlagen, die eine hohe Leistung ermöglichen bei geringem apparativen Aufwand und hoher Sicherheit gegen Störanfälligkeit.The invention has for its object to propose measures for a rational connection of webs, which allow high performance with low equipment costs and high security against susceptibility.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Splice-Verfahren durch folgende Merkmale gekennzeichnet:

  1. a) die Ablaufbahn wird bei Einleitung des Splice-Vorgangs während der fortlaufenden Bewegung mit einem beidseitig klebenden Tape versehen,
  2. b) ein vorbereitetes Ende - Anfangsstück - der Neubahn wird in einem Abstand von der Ablaufbahn bereitgehalten,
  3. c) zur Verbindung mit der Ablaufbahn wird das Anfangsstück der Neubahn an die Ablaufbahn gedrückt, wenn das mit der Ablaufbahn geförderte Tape dem Anfangsstück der Neubahn gegenüberliegt,
  4. d) unmittelbar nach Verbindung von Ablaufbahn und Neubahn wird die Ablaufbahn durchtrennt.
To solve this problem, the splicing method according to the invention is characterized by the following features:
  1. a) the runway is provided at the initiation of the splicing process during the continuous movement with a double-sided adhesive tape,
  2. b) a prepared end - initial piece - the new rail is kept at a distance from the runway,
  3. c) for connection to the runway, the start piece of the new reel is pressed against the run-off track when the tape conveyed with the run-flat path is opposite the beginning piece of the new web,
  4. d) immediately after the connection of the runway and the new runway the runway is severed.

Bei diesem Verfahren wird die Zuführung des bahnförmigen Verpackungsmaterials nicht unterbrochen, sondern im Wesentlichen mit unveränderter Fördergeschwindigkeit aufrecht erhalten.In this method, the supply of the web-shaped packaging material is not interrupted, but maintained substantially unchanged in conveying speed.

Die Neubahn wird erfindungsgemäß so vorbereitet, dass ein insbesondere durch Druckmarken oder andere Kennzeichen an der Bahn vorbestimmbares Anfangsstück in exakter Relativlage gegenüber der Ablaufbahn bereitgehalten und bei im Wesentlichen unveränderter Fördergeschwindigkeit durch die Ablaufbahn über das doppelseitig klebenden Tape mitgenommen. Von besonderer Bedeutung ist die Zuführung des Tapes zur Ablaufbahn durch einen Tapeförderer bzw. eine Taperolle, die kurzfristig auf die Bewegungsgeschwindigkeit der Ablaufbahn beschleunigt wird zur Übergabe des Tapes an diese.According to the invention, the new reed is prepared in such a way that an initial piece, predeterminable in particular by printed marks or other markings on the web, is held in exact relative position with respect to the runway and taken along at substantially the same conveying speed by the runway via the double-sided adhesive tape. Of particular importance is the feeding of the tape to the runway by a tape conveyor or a Taperolle which is accelerated at short notice on the speed of movement of the runway to the transfer of the tape to this.

Die erfindungsgemäße Vorrichtung umfasst eine Splice-Einheit mit jeder Bahn zugeordneter Bahnwalze, von denen mindestens eine achsparallel verstellbar ist zur Schaffung von unterschiedlichen Abständen der benachbarten Bahnwalzen voneinander. Des Weiteren ist jeder Bahnwalze eine Taperolle zugeordnet. Diese ist jeweils mit einem Trennmesser versehen, welches in korrekter Relativstellung zum Tape die Ablaufbahn durchtrennt, und zwar im Zusammenwirken mit der jeweiligen Bahnwalze.The device according to the invention comprises a splicing unit with a web roll assigned to each web, of which at least one axis-parallel is adjustable in order to create different distances of the adjacent web rolls from one another. Furthermore, each web roll is assigned a taper roller. This is in each case provided with a separating knife, which cuts through the runway in the correct relative position to the tape, in cooperation with the respective web roll.

In Fig. 5 , A snapshot at the beginning of a web change operation, the web roll 23 of the process sheet 13 and the web roll 24 of the new rail 15 is assigned. The webs 13, 15 each run in a region of 90 ° around the web rolls 23, 24, namely from a horizontal conveying plane into a vertical conveying plane. The web rolls 23, 24 are mounted parallel to the axis and at a variable distance from each other, such that between the web rolls 23, 24, a gap of different width for the passage of the webs 13, 15 is provided.

Jeder Bahnwalze 23, 24 ist eine Taperolle 25, 26 zugeordnet. Diese sind oberhalb der zugeordneten Bahnwalze 23, 24 gelagert. Die Taperollen 25, 26 dienen zur Zuführung des Tapes 22 zur jeweiligen Ablaufbahn 13 und zum Anlegen des Tapes 22 an diese. Das beidseitig klebende Tape 22 ist in einem besonderen Umfangsbereich der Taperolle 25, 26 positioniert, der eine geringere Haftung des Tapes 22 aufweist, insbesondere im Bereich einer Silikonbeschichtung 27 der Taperolle 25, 26.Each web roll 23, 24 is assigned a taper roller 25, 26. These are mounted above the associated web roll 23, 24. The Taperollen 25, 26 are used to supply the tape 22 to the respective runway 13 and for applying the tape 22 to this. The double-sided adhesive tape 22 is positioned in a special peripheral region of the tapered rollers 25, 26, which has a lower adhesion of the tape 22, in particular in the region of a silicone coating 27 of the tapered rollers 25, 26.

Eine Besonderheit ist die Anbringung eines Trennmessers 28 an der Taperolle 25, 26. Das Trennmesser 28 wirkt mit der jeweiligen Bahnwalze 23, 24 zusammen, auf der die Ablaufbahn 13 aufliegt. Der Trennschnitt wird durch das Trennmesser 28 auf der entsprechend ausgebildeten, nämlich gehärteten Oberfläche der Bahnwalze 23, 24 ausgeführt. Durch die Verbindung mit der Taperolle 25, 26 folgt der Trennschnitt in exaktem Abstand zu dem aufgelegen Tape 22. Zwischen den beiden Bahnwalzen 23, 24 befindet sich ein annähernd dreieckförmige Führungskörper 29, der die Bahnen 13, 15 jeweils im Bereich der Anlage an den Bahnwalzen 23, 24 führt.A special feature is the attachment of a separating knife 28 on the taper roller 25, 26. The cutting knife 28 cooperates with the respective web roll 23, 24, on which the run-off path 13 rests. The separating cut is carried out by the separating knife 28 on the correspondingly formed, namely hardened surface of the web roll 23, 24. By the connection with the Taperolle 25, 26 follows the separating cut at an exact distance to the aufgelagegen tape 22. Between the two web rolls 23, 24 is an approximately triangular guide body 29, the webs 13, 15 each in the area of the system to the web rolls 23, 24 leads.

Die Bahnwalzen 23, 24 und die Taperollen 25, 26 sind mit Achszapfen bzw. Antriebswellen in Tragwänden 30, 31 eines Traggestells drehbar gelagert (Fig. 9). Die Taperolle 25, 26 wird durch einen Motor 32 angetrieben, der über eine Welle 33 mit Kupplung 34 auf die Taperolle 25, 26 einwirkt.The track rollers 23, 24 and the Taperollen 25, 26 are rotatably mounted with axle journals or drive shafts in support walls 30, 31 of a support frame ( Fig. 9 ). The Taperolle 25, 26 is driven by a motor 32 which acts via a shaft 33 with coupling 34 on the Taperolle 25, 26.

Die relative, achsparallele Verstellung der Bahnwalzen 23, 24 zueinander wird durch ein Exzentergetriebe bewirkt. Bei dem gezeigten Beispiel ist lediglich die Bahnwalze 24 auf einer Exzenterwelle 35 gelagert, die versetzt zu einer Antriebswelle 36 verläuft. Die Exzenterwelle 35 ist durch ein gesondertes Getriebe drehbar, und zwar durch einen auf der Exzenterwelle 35 angebrachten Schwenkarm 37, der mit einem (Druckmittel-)Zylinder 38 bzw. mit dessen Kolbenstange verbunden ist. Durch Betätigen des Exzentergetriebes wird die Bahnwalze 24 quer bewegt unter Verringerung oder Vergrößerung des Abstands von der anderen Bahnwalze 23.The relative, axially parallel adjustment of the web rolls 23, 24 to each other is effected by an eccentric gear. In the example shown, only the web roll 24 is mounted on an eccentric shaft 35, which extends offset to a drive shaft 36. The eccentric shaft 35 is rotatable by a separate gear, by a mounted on the eccentric shaft 35 pivot arm 37 which is connected to a (pressure medium) cylinder 38 and with its piston rod. By operating the eccentric gear, the web roll 24 is moved transversely to reduce or increase the distance from the other web roll 23.

Zu der Splice-Einheit 19 gehören weiterhin Schneidorgane zum positionsgenauen Durchtrennen der jeweiligen Neubahn 15 vor Beginn des Wechselvorgangs. Es handelt sich dabei um jeweils ein quer zur Neubahn 15 bewegbares, rollen- bzw. scheibenförmiges Messer 39. Dieses ist an einer Halterung 40 auf der Tischplatte 20 angebracht. Das Messer 39 sitzt an einem Schlitten 41, der von Hand quer über die Neubahn 15 bzw. quer über die Tischplatte 20 bewegbar ist. Der Schlitten 41 ist zu diesem Zweck auf einer Führungsstange 42 verschiebbar gelagert. Das drehende Messer 39 arbeitet bei Durchführung des Trennschnitts mit einer Rechtkante bzw. Richtschiene 43 auf der Tischplatte 20, also unterhalb der Neubahn 15, zusammen. Die Richtschiene 43 gewährleistet zusammen mit dem Messer 39 einen exakten, präzisen Trennschnitt der Neubahn 15, insbesondere an markierter bzw. definierter Position.To the splice unit 19 further includes cutting members for positionally accurate severing of the respective new web 15 before the beginning of the change process. It is in each case a transversely to Neubahn 15 movable, roller or disc-shaped knife 39. This is attached to a bracket 40 on the table top 20. The knife 39 is seated on a carriage 41, which is movable by hand across the new web 15 or across the table top 20. The carriage 41 is slidably mounted on a guide rod 42 for this purpose. The rotating blade 39 works when performing the separating cut with a right edge or horizontal rail 43 on the table top 20, ie below the new rail 15, together. The alignment rail 43, together with the knife 39, ensures an exact, precise separation cut of the new web 15, in particular at the marked or defined position.

Weiterhin gehört zur Splice-Einheit 19 ein in Förderrichtung auf die Bahnwalzen 23, 24 folgender Bahnspeicher 44. Dieser bildet mit Hilfe von ortsfesten Umlenkrollen 45 und mit diesen zusammenwirkenden weiteren Umlenkrollen 46 an einem Arm 47 mehrere Bahnschleifen, die durch Schwenkbewegung des Arms 47 vergrößert oder verkleinert werden können. Einem Drehlager 48 des Arms 47 ist ein Sensor 49 zugeordnet, der die exakte Winkelstellung des Drehlagers 48 und damit des Arms 47 erkennt. Aus der Stellung des Drehlagers 48 ergibt sich die Speicherlänge der Ablaufbahn 13. Der Sensor 49 steuert den Antrieb der Bobinen 14, 16 bzw. der Tragzapfen 10, 11.Furthermore, one of the splice unit 19 in the conveying direction on the web rolls 23, 24 following web memory 44. This forms by means of stationary pulleys 45 and cooperating with these further pulleys 46 on an arm 47 a plurality of track loops, which increases by pivoting movement of the arm 47 or can be downsized. A pivot bearing 48 of the arm 47 is associated with a sensor 49 which detects the exact angular position of the pivot bearing 48 and thus of the arm 47. From the position of the pivot bearing 48 results in the memory length of the process path 13. The sensor 49 controls the drive of the reels 14, 16 and the trunnions 10, 11th

Eine Besonderheit sind die ausgewählten Antriebe nach Maßgabe der Funktion und Wirtschaftlichkeit. Die Bobinen 14, 16 bzw. die Tragzapfen 10, 11 werden jeweils durch Drehstrommotoren 50, 51 angetrieben. Diese können kurzfristig auf die erforderliche Drehgeschwindigkeit hochgefahren werden, dienen aber auch als Motorbremse. Die Bahnwalzen 23, 24 sowie die Taperollen 25, 26 werden hingegen durch Schrittmotoren angetrieben, also einer einfacheren Ausführung eines Servomotors. Die Schrittmotoren gewährleisten jeweils exakte Bewegungsschritte.A special feature are the selected drives in accordance with the function and efficiency. The bobbins 14, 16 and the support pins 10, 11 are each driven by three-phase motors 50, 51. These can be quickly raised to the required rotational speed, but also serve as an engine brake. The web rolls 23, 24 and the Taperollen 25, 26, however, are driven by stepper motors, so a simpler design of a servomotor. The stepper motors ensure precise movement steps.

Bei einem Bahn- bzw. Bobinenwechsel wird mit der beschriebenen Vorrichtung wie folgt vorgegangen: Rechtzeitig vor Beginn des Bahnwechsels wird die Neubahn 15 (manuell) vorbereitet. Hierzu wird ein von der Neubobine 16 abgezogenes Anfangsstück 52 der Neubahn 15 in eine exakte Position gebracht, die sich aus Fig. 5 ergibt. Die Neubahn 15 bzw. das Anfangsstück 52 erstreckt sich bis in den Bereich des geringsten Abstandes der Bahnwalzen 23, 24 voneinander und etwas darüber hinaus. Diese exakte Länge des Anfangsstücks 52 wird beim Bilden einer Anfangskante der Neubahn 15 mit Hilfe des Messers 39 geschaffen. Dabei wird der Trennschnitt an vorgegebener Position durchgeführt, nämlich unter Bezugnahme auf eine an der Bahn angebrachte Druckmarke oder eine gestalterische Bedruckung der Neubahn 15. Das mit dem Trennschnitt des Messers 39 geschaffenen Anfangsstück 52 wird durch eine mechanische Messeinrichtung bestimmt. Zu diesem Zweck wird eine Bahnschleife 53 gezogen zwischen den beiden Umlenkwalzen 17, 18, und zwar mit einer bewegbaren Zwischenwalze 54, die zwischen den Umlenkwalzen 17, 18 quer bewegt wird unter Mitnahme einer bestimmten Länge der Neubahn 15 (Fig. 3, rechts). Die Zwischenwalze 54 ist an einem Betätigungsarm 55 angebracht, der aus einer in Fig. 3 links gezeigten Ausgangsposition in die in Fig. 3 rechts gezeigte Arbeitsstellung bewegt wird. In der Ausgangsstellung ist der Zwischenwalze 54 ein Überwachungsorgan zugeordnet, nämlich ein Initiator 56. Dieser stellt sicher, dass der Bahnwechselvorgang erst nach Bildung der Bahnschleife 53 eingeleitet wird. In der Stellung gemäß Fig. 3, rechts kann nun (von Hand) der Trennschnitt mittels Messer 39 durchgeführt werden zur Schaffung einer exakten Vorderkante der Neubahn 15.In the case of a change of track or bobbin, the procedure described is as follows: In time before the start of the change of course, the new line 15 is prepared (manually). For this purpose, a deducted from the Neubobine 16 initial piece 52 of the new rail 15 is brought into an exact position, which is made Fig. 5 results. The new web 15 or the starting piece 52 extends into the region of the smallest distance of the web rolls 23, 24 from each other and slightly beyond. This exact length of the initial piece 52 is created in forming a leading edge of the new web 15 by means of the knife 39. In this case, the separating cut is carried out at a predetermined position, namely with reference to a printed mark applied to the web or design printing of the new web 15. The initial piece 52 created by the separating cut of the knife 39 is determined by a mechanical measuring device. For this purpose, a web loop 53 is drawn between the two guide rollers 17, 18, with a movable intermediate roller 54 which is moved transversely between the guide rollers 17, 18, taking along a certain length of the new rail 15 (FIG. Fig. 3 , right). The intermediate roller 54 is attached to an actuating arm 55, which consists of a in Fig. 3 shown on the left in the in Fig. 3 right shown working position is moved. In the initial position of the intermediate roller 54 is assigned a monitoring element, namely an initiator 56. This ensures that the web change operation is initiated only after the formation of the web loop 53. In the position according to Fig. 3 , right now can be performed by hand, the separation cut by means of knife 39 to create an exact leading edge of the new rail 15.

Der Betätigungsarm 55 mit Zwischenwalze 54 kehrt danach in die Ausgangsstellung zurück. Für die manuelle Einführung des Anfangsstücks 52 der Bahn in die Splice-Position (Fig. 5, Fig. 6) steht nun ein hinsichtlich der Länge exakt bemessenes Anfangsstück 52 der Neubahn 15 zur Verfügung.The actuating arm 55 with intermediate roller 54 then returns to the starting position. For manual insertion of the leader 52 of the web into the splice position (FIG. Fig. 5, Fig. 6 ) is now in terms of length exactly sized initial piece 52 of the new lug 15 available.

Es wird sodann das Tape 22 auf die der Ablaufbahn 13 zugeordnete Taperolle 25 aufgelegt, und zwar im Bereich der Silikonbeschichtung 27 (Fig. 5). Bei unverändert weiter laufender Ablaufbahn 13 wird das Tape 22 auf die Ablaufbahn 13 übertragen (Fig. 6). Dazu ist es erforderlich, die Taperolle 25 während einer Teildrehung auf die Geschwindigkeit der Ablaufbahn 13 zu beschleunigen. Dies wird in der Weise erreicht, dass die Taperolle 25 zunächst in entgegengesetzter Richtung gedreht wird (Fig. 5) und sodann nach dieser "Ausholbewegung" bei Drehrichtungsumkehr auf die Geschwindigkeit der Neubahn 15 beschleunigt wird bis zur Übergabe des Tapes 22 (Fig. 6).It is then the tape 22 is placed on the runway 13 associated Taperolle 25, in the region of the silicone coating 27 (FIG. Fig. 5 ). If the runway 13 continues to run unchanged, the tape 22 is transferred to the runway 13 ( Fig. 6 ). For this purpose, it is necessary to accelerate the Taperolle 25 during a partial rotation to the speed of the Ablaufbahn 13. This is achieved in such a way that the taper roller 25 is first rotated in the opposite direction ( Fig. 5 ) and then after this "Ausholbewegung" when reversing the direction of rotation on the speed of the new rail 15 is accelerated until the transfer of the tape 22 (FIG. Fig. 6 ).

Unmittelbar nach Übergabe des Tapes 22 an die Ablaufbahn 13 wird die das Anfangsstück 52 der Neubahn 15 haltende Bahnwalze 24 durch Betätigen des Zylinders 38 verstellt auf einen geringen Abstand von der gegenüberliegenden Bahnwalze 23 (Fig. 6). Des Weiteren wird die Bahnwalze 24 ebenfalls drehend angetrieben. Wenn das Tape 22 in den Bereich des geringsten Abstandes zwischen den beiden Bahnwalzen 23, 24 gelangt, erfolgt eine klebende Verbindung mit dem Anfangsstück 52. Die nachfolgende Neubahn 15 wird nun durch die Ablaufbahn mitgezogen. Zugleich ist infolge fortgesetzter Drehbewegung der Taperolle 25 das zu dieser gehörende Trennmesser 28 wirksam geworden und hat die Ablaufbahn 13 an der Oberseite der Bahnwalze 23 durchtrennt (Fig. 7, Fig. 8) unter Bildung des Reststücks 21. Die (neue) Ablaufbahn 13 wird mit unveränderter Geschwindigkeit gefördert, wobei ein genau definierter Zuschnitt im Bereich der Tapeverbindung später ausgesondert wird.Immediately after transfer of the tape 22 to the run-off track 13, the web roller 24 holding the starting piece 52 of the new web 15 is adjusted by actuating the cylinder 38 to a small distance from the opposite web roll 23 (FIG. Fig. 6 ). Furthermore, the web roll 24 is also driven in rotation. If the tape 22 reaches the area of the smallest distance between the two web rolls 23, 24, there is an adhesive connection with the starting piece 52. The following new sheet 15 is now pulled along by the runway. At the same time as a result of continued rotational movement of the taper roller 25 belonging to this separating knife 28 has become effective and has the runway 13 at the top of the web roll 23 severed ( Fig. 7, Fig. 8 ) with the formation of the remainder piece 21. The (new) run-off track 13 is conveyed at the same speed, whereby a precisely defined blank in the area of the tape connection is later separated out.

Gewisse Schwankungen bei der Fördergeschwindigkeit der Ablaufbahn 13 werden durch den Bahnspeicher 44 ausgeglichen, wobei Abweichungen von einer Mittelstellung über den Sensor 49 erfasst und als Steuersignal dem Drehstrommotor 50, 51 des einen oder anderen Tragzapfens 10, 11 zugeleitet werden mit der Folge einer Verzögerung oder Erhöhung der Drehgeschwindigkeit.Certain fluctuations in the conveying speed of the process path 13 are compensated by the web memory 44, wherein deviations are detected by a center position via the sensor 49 and fed as a control signal to the three-phase motor 50, 51 of one or the other trunnions 10, 11 with the result of a delay or increase the rotational speed.
