Abstract

Plastic packaging films are ultrasonically welded in binding round or sealing packages or stacks longitudinally in reference to their direction of movement; in the process the packages/stacks are passed through a curtain of the film so that they are covered on three sides, and a strip of the curtain is projected so as to cover the fourth side behind the package/stack. A device takes a loop of the curtain over an ultrasonic welding head to a cutter. ADVANTAGE - The process has the advantages of ultrasonic over thermal welding i.e. avoids the problems arising with heating and it enables the material to be prepd. immediately for use.

Description

Die Erfindung betrifft ein Ultraschall-Schweißverfahren das ermöglicht, Pakete und Stapel vornehmlich von Zeitun­ gen und Illustrierten und Pappen, in Längsrichtung zu ihrer Bewegungsrichtung in Verpackungslinien kontinuierlich mit­ tels Kunststoffbändern zu umreifen und zu verschließen.The invention relates to an ultrasonic welding process this enables parcels and stacks primarily from Zeitun and magazines and cardboards, lengthways to her Direction of movement in packaging lines continuously strapping and sealing with plastic straps.

Bei herkömmlichen Verpackungslinien zum Umreifen von Paketen oder Stapeln mit Verpackungsbändern, ist es erforderlich, auch Umreifungen in Längsrichtung zu der Bewegungsrichtung der Pakete oder Stapel, durchzuführen. Bisher wurden zum Ver­ schließen dieser Umreifungen Heißschweiß-Verfahren benutzt. Im Gegensatz hierzu arbeitet das Ultraschall-Schweißverfahren mit nach außen hin nicht in Erscheinung tretender Erwärmung und damit sofortiger Betriebsbereitschaft.With conventional packaging lines for strapping packages or stacking with packing tapes, it is necessary also strapping in the longitudinal direction to the direction of movement of the packets or stacks. So far, ver close this strapping used hot welding process. In contrast, the ultrasonic welding process works with warming that does not appear to the outside and thus immediate operational readiness.

Aufgabe der Erfindung ist es, diese Vorteile des Ultraschall- Schweißverfahrens in Verpackungslinien zum Umreifen und Ver­ schließen von Paketen oder Stapeln mit Kunststoff-Verpackungs­ bändern in Längsrichtung zu der Bewegungsrichtung der Pakete oder Stapel, vorzunehmen.The object of the invention is to take advantage of ultrasound Welding process in packaging lines for strapping and packaging closing packages or stacks with plastic packaging tapes longitudinally to the direction of movement of the packets or stack.

Das zu umgreifende Paket oder der Stapel wird durch einen an sich bekannten Verpackungsband-Vorhang geführt und damit auf drei Seiten von dem Kunststoff-Verpackungsband umhüllt und durch einen Kunststoffband-Finger der Bandvorhang zunächst um die noch offene hintere Seite vom Paket oder dem Stapel geführt. Gemäß der Er­ findung wird nun der Kunststoffband-Vorhang als offene Schlaufe mit einem Kunststoffband-Überbringer in die Ultraschall-Verschließ­ einrichtung gebracht. Die Verschließeinrichtung übernimmt diese Kunststoffband-Schlaufe und legt und schneidet sie mittels Zangen und Messer so zurecht, daß der sich bewegende Ultraschall-Schweiß­ kopf eine zweifache Überlappungs-Schweißung des Kunststoff-Umrei­ fungsbandes vornehmen kann. Durch diese zweifache Überlappungs­ schweißung wird erreicht, daß die für die Festigkeit der Umreifung erforderliche Überlappungslänge an das Paket oder den Stapel ange­ schmiegt mit dem eigentlichen Paket- oder Stapel-Umreifungsband verschweißt wird und vom Paket oder Stapel nicht absteht. The package or stack to be wrapped is one by itself known packaging tape curtain and thus on three Sides of the plastic packaging tape and wrapped by one Plastic tape fingers the tape curtain first around the still open one rear side of the package or the stack. According to the Er The plastic tape curtain is now found as an open loop a plastic tape deliverer in the ultrasonic sealer facility brought. The closing device takes care of this Plastic strap loop and puts and cuts it using pliers and knives so that the moving ultrasound sweat head a double overlap weld of the plastic outline tion band can make. Because of this double overlap Welding is achieved for the strength of the strapping required length of overlap to the package or stack nestles with the actual package or stack strapping is welded and does not protrude from the package or stack.  

Der neu abgeschnittene Kunststoffband-Anfang wird unterhalb der Paket- oder Stapelbewegungs-Ebene zur Bildung eines neuen Um­ reifungsband-Vorhanges in einer Zange festgehalten. Hiermit steht das Ultraschall-Schweißverfahren für einen neuen Arbeitszyklus bereit.The newly cut plastic tape start is below the Packet or stack movement level to form a new order maturing tape curtain held in pliers. Hereby stands the ultrasonic welding process for a new working cycle ready.

In den folgenden Figuren ist dieser Arbeitszyklus näher erläutert. InThis working cycle is explained in more detail in the following figures. In

Fig. 1 bildet die Vorratsspule 1 für das Kunststoffband, dessen Anfang in der rechten Unterzange 2 und der rechten Oberzange 3 unter der Paket- oder Stapel-Bewegungsebene 5 festgehalten wird, einen Kunststoffband-Vorhang 6. Das Paket oder der Stapel 4 bewegt sich in Pfeilrichtung zum Kunststoffband-Vorhang 6. In Fig. 1 forms the supply reel 1 for the plastic tape, the beginning of which is held in the right lower pliers 2 and the right upper pliers 3 under the package or stack movement plane 5 , a plastic tape curtain 6 . The package or stack 4 moves in the direction of the arrow toward the plastic tape curtain 6 . In

Fig. 2 hat das Paket oder der Stapel 4 den Kunststoffband-Vor­ hang 6 durchfahren und wird dabei vom Kunststoffband-Vorhang 6 auf drei Seiten eingehüllt. Die Ultraschall-Schweißgegenplatte 8 wird in die Umreifungsebene zwischen Paket- oder Stapel-Unterseite und der Oberseite vom Kunststoffband-Vorhang 6 geschoben. Die linke Zange 7 hält das Kunststoffband unter der Ultraschall-Schweißgegenplatte 8 fest. Die rechte Oberzange 3 gibt den Kunststoffband-Anfang frei, der Glattstreifer 9 glättet sporadisch den von der Oberzange 3 frei­ gegebenen Kunststoffband-Anfang unter der Ultraschall-Schweißgegen­ platte 8. In Fig. 2, the package or stack 4 has passed through the plastic band Before hang 6 and is thereby wrapped by the plastic strip curtain 6 on three sides. The ultrasonic welding counterplate 8 is pushed into the strapping plane between the bottom of the package or stack and the top of the plastic band curtain 6 . The left pliers 7 hold the plastic band under the ultrasonic welding counter plate 8 . The right upper pliers 3 releases the start of the plastic band, the smooth stripper 9 sporadically smoothes the start of the plastic band released by the top pliers 3 under the ultrasonic welding counter plate 8 . In

Fig. 3 legt der Kunststoffband-Finger 10 den Kunststoffband-Vor­ hang 6 um die hintere Seite von Paket oder Stapel 4. In Fig. 3 sets the plastic tape finger 10, the plastic tape before hang 6 around the rear side of the package or stack 4th In

Fig. 4 bringt der Kunststoffband-Überbringer 11 den Kunststoff­ band-Vorhang 6 in einer offenen Schlaufe 12 über den Ultraschall- Schweißkopf 13. In Fig. 4 brings the plastic tape deliverer 11, the plastic tape curtain 6 in an open loop 12 over the ultrasonic welding head 13th In

Fig. 5 wird die rechte Oberzange 3 in die offene Schlaufe 12 ge­ führt. Der Ultraschall-Schweißkopf 13 bewegt sich in Richtung der Ultraschall-Schweißgegenplatte 8. Voraus eilt die rechte Unterzange 2, die sich gegen die rechte Oberzange 3 klemmt und an ihrer Seite ein geringfügig nacheilendes Messer 14 führt, das die mit der rechten Unterzange 2 angeklemmte, offene Schlaufe 12 so abschneidet, daß der ankommende Ultraschall-Schweißkopf 13 das bereits um das Paket oder den Stapel gelegte Kunststoffumreifungsband mit dem Kunststoffband- Anfang und der aufgeschnittenen, offenen Schlaufe 12, durch eine zweifache Überlappungsschweißung verbindet. Fig. 5, the right upper pliers 3 leads into the open loop 12 ge. The ultrasonic welding head 13 moves in the direction of the ultrasonic welding counterplate 8 . In advance rushes the right lower pliers 2 , which clamps against the right upper pliers 3 and carries a slightly lagging knife 14 on their side, which cuts off the open loop 12 clamped with the right lower pliers 2 so that the incoming ultrasonic welding head 13 already does this around the package or the stack of plastic strapping connected to the beginning of the plastic band and the cut open loop 12 , by means of a double overlap weld.

Die Ultraschall-Schweißgegenplatte 8, die linke Zange 7, der Bandüberbringer 11, der Bandfinger 10, sowie der Ultra­ schall-Schweißkopf 13 kehren in ihre jeweiligen Ausgangs­ lagen zurück und das fertig umreifte Paket oder der Stapel ist freigegeben.The ultrasonic welding counter plate 8 , the left pliers 7 , the band transferring 11 , the band finger 10 , and the ultrasonic welding head 13 return to their respective starting positions and the finished strapped package or the stack is released.

In Fig. 6 hat die rechte Zange zwischen ihrer rechten Unterzange 2 und ihrer rechten Oberzange 3 den neuen Kunststoffband-Anfang unterhalb der Paket- oder Stapel-Bewegungsebene festgeklemmt. Zwischen sich und der Kunststoffband-Vorratsspule 1 bildet sich dadurch ein neuer Kunststoffband-Vorhang 6, der für den neuen Arbeitszyklus bereitsteht.In Fig. 6, the right pliers between their right lower pliers 2 and their right upper pliers 3 have clamped the new plastic band start below the package or stack movement plane. A new plastic tape curtain 6 is thus formed between itself and the plastic tape supply spool 1 , which is ready for the new working cycle.
