Description

Die Erfindung bezieht sich auf eine Maschine zum Einhüllen eines elastisch komprimierbaren Stapels, insbesondere von Druckschriften und Zeitungen, in eine Folienbanderole und zum Umreifen des umhüllten Stapels mit einem Band, die einen Einlauf-Flachförderer für den Stapel, einen mit Zwischenraum sich daran anschließenden Fördertisch, Einrichtungen zur Bildung eines den Zwischenraum durchlaufenden Folienvorhangs, eine über dem Fördertisch angeordnete Preßeinrichtung zum Zusammenpressen des Stapels vor dem Schließen der Banderole, eine hinter dem Folienvorhang angeordnete Schweißeinrichtung zum Schließen und Abschweißen der vom Folienvorhang um einen auf dem Fördertisch liegenden Stapel gebildeten Banderole zum Schließen und Abschweißen der vom Folienvorhang um einen auf dem Fördertisch liegenden Stapel gebildeten Banderole und eine mit dem in der Schweißstellung auf dem Fördertisch liegenden Stapel zusammenwirkenden Umreifungseinrichtung sowie eine Steuereinrichtung umfaßt.The invention relates to a machine for wrapping an elastically compressible stack, in particular of printed matter and newspapers, in a foil band and for strapping the wrapped stack with a belt, which has an infeed flat conveyor for the stack, a conveyor table adjoining it, Means for forming a film curtain passing through the intermediate space, a pressing device arranged above the conveyor table for pressing the stack together before closing the banderole, a welding device arranged behind the film curtain for closing and welding the banderole formed by the film curtain around a stack lying on the conveyor table for closing and Welding the banderole formed by the film curtain around a stack lying on the conveyor table and one with the strapping device interacting in the welding position on the conveyor table and comprising a control device.

Es ist eine Maschine dieser Art bekannt (DE-A-19 63 531), in welcher der zu verpackende Zeitschriftenstapel auf dem Einlaufförderband von einem Preßbalken erfaßt wird, der mit dem Stapel weiterläuft, bis dieser auf dem Fördertisch die Stellung erreicht hat, in der er von der Banderole des Folienvorhangs umhüllt ist und später verschweißt wird. Der Preßbalken wird dann zurückgezogen und die Banderole wird durch den Schweißvorgang geschlossen und von dem Folienvorhang abgetrennt. Danach senkt sich auf den in seiner Stellung verharrenden Stapel die Umreifungseinrichtung herab, um die Umreifung durchzuführen.A machine of this type is known (DE-A-19 63 531) in which the stack of magazines to be packaged on the infeed conveyor belt is gripped by a press beam which continues to run with the stack until it has reached the position on the conveyor table in which it is wrapped in the banderole of the foil curtain and is later sealed. The press beam is then withdrawn and the banderole is closed by the welding process and separated from the film curtain. The strapping device then lowers onto the stack which remains in its position in order to carry out the strapping.

In der Praxis ist es jedoch üblich geworden, den Umhüllungsprozeß vom Umschnürungsprozeß derart zu trennen, daß zwei gesonderte Maschinen hintereinander angeordnet werden. Dies geht zum einen darauf zurück, daß zumindest in Europa nicht dieselben Hersteller für die Produktion von Umhüllungs-und Umreifungsmaschinen in Frage kommen; das zugehörige Herstellungs- und Wartungs-Know-how ist vielmehr industriell getrennt. Außerdem wünschen die Verbraucher, daß bei einem Schaden der einen Maschine diese ersetzt werden kann, ohne daß auch gleichzeitig die andere ersetzt werden muß. Indessen ist natürlich der Aufwand für die Herstellung zweier Maschinen größer als derjenige für eine einzige Maschine.In practice, however, it has become common to separate the wrapping process from the strapping process in such a way that two separate machines are arranged one behind the other. On the one hand, this is due to the fact that, at least in Europe, the same manufacturers are not suitable for the production of wrapping and strapping machines; the associated manufacturing and maintenance know-how is rather separated industrially. In addition, consumers wish that if one machine is damaged, it can be replaced without the other having to be replaced at the same time. However, the effort to manufacture two machines is of course greater than that for a single machine.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Maschine der eingangs genannten Art zu schaffen, die den europäischen Herstellungs- und Wartungsvoraussetzungen angepaßt ist und dennoch unaufwendig ist.The invention is therefore based on the object to provide a machine of the type mentioned, which is adapted to the European manufacturing and maintenance requirements and is still inexpensive.

Die erfindungsgemäße Lösung besteht darin, daß die Maschine aus zwei gesonderten, steuerungsmäßig verbindbaren Maschineneinheiten besteht, von denen die erste den Einlauf-Flachförderer, die Einrichtungen zur Bildung des Folienvorhangs und die Schweißeinrichtung und die zweite wenigstens einen Teil des Fördertisches und die Preß- und Umreifungseinrichtung umfaßt.The solution according to the invention consists in that the machine consists of two separate machine units which can be connected in terms of control, the first of which is the flat infeed conveyor, the devices for forming the film curtain and the welding device and the second at least part of the conveyor table and the pressing and strapping device includes.

Bei den herkömmlichen, hintereinander geschalteten Umhüllungs-und Umreifungsmaschinen war es selbstverständlich, daß jede Maschine für sich eine selbständig und unabhängig betreibbare Einheit darstellte, jeweils mit einem Einlauf-Förderband und einem Fördertisch, auf welchem die jeweils vorzunehmende Bearbeitung stattfindet. Von diesem Prinzip geht die Erfindung ab; jede Einheit wird sozusagen nur halb ausgeführt und durch die andere ergänzt, indem die eine Maschineneinheit lediglich das Einlauf-Förderband und die andere den für beide Bearbeitungsschritte verwendeten Fördertisch umfaßt. Dabei wird gleichwohl der Vorteil aufrechterhalten, daß die beiden Einheiten von unterschiedlichen Herstellern stammen können, die jeweils das Know-how der Umhüllungstechnik einerseits und der Umreifungstechnik andererseits beherrschen und auch jeweils die Wartung an den von ihnen stammenden Maschinen ohne Rücksicht auf die andere durchführen können. Im Betrieb tritt die scheinbar paradoxe Situation ein, daß die zu umhüllenden Gegenstände bereits in der zweiten Maschine angekommen sind, wenn die der ersten Maschine zugehörigen Verarbeitungsschritte vollzogen werden.With the conventional wrapping and strapping machines connected in series, it was a matter of course that each machine represented an independently and independently operable unit, each with an infeed conveyor belt and a conveyor table on which the processing to be carried out takes place. The invention proceeds from this principle; each unit is, so to speak, only half completed and supplemented by the other, in that one machine unit only comprises the infeed conveyor belt and the other the conveyor table used for both processing steps. Nevertheless, the advantage is maintained that the two units can come from different manufacturers, each of which have mastery of the know-how of wrapping technology on the one hand and strapping technology on the other hand and can also carry out maintenance on the machines they produce, regardless of the other. In operation, the apparently paradoxical situation arises that the objects to be wrapped have already arrived in the second machine when the processing steps associated with the first machine are carried out.

Damit der funktionelle übergang gewährleistet ist, sind die Maschineneinheiten zweckmäßigerweise formschlüssig aneinander anschließend ausgebildet.To ensure the functional transition, they are Machine units are expediently formed in a form-fitting manner.

Die Preßeinrichtung zum Zusammenpressen des Stapels, bevor die diesen umhüllende Banderole geschlossen wird, wird vorteilhafterweise von der Umreifungseinrichtung gebildet. Es ist dann lediglich eine Preßeinrichtung erforderlich. Nach einem besonderen Merkmal der Erfindung kann die Steuereinrichtung so ausgebildet sein, daß das Umreifen spätestens gleichzeitig, besser aber vor dem Schließen der Banderole erfolgt. Dann wird nämlich die nach dem Zusammenpressen des Stapels darin gespeicherte Dehnkraft von der Umreifung aufgenommen und die Schweißnaht der Banderole entsprechend entlastet. Das ergibt den Vorteil, daß die Schweißwerkzeuge bzw. die den Stapel zusammendrückende Preßeinrichtung gelöst werden können, bevor die Schweißnaht erkaltet und damit widerstandsfähig geworden ist. Die Einsparung derjenigen Zeit, die normalerweise für die Auskühlung der Schweißnaht erforderlich ist, kann zu einer beträchtlichen Kürzung der Taktzeit benutzt werden.The pressing device for compressing the stack before the band enveloping it is advantageously formed by the strapping device. Then only a press device is required. According to a special feature of the invention, the control device can be designed so that the strapping takes place at the same time at the latest, but better before the band is closed. Then the stretching force stored in it after the stack is compressed is absorbed by the strapping and the weld seam of the sleeve is relieved accordingly. This has the advantage that the welding tools or the pressing device which compresses the stack can be released before the weld seam has cooled and has thus become resistant. The saving of the time normally required for the cooling of the weld seam can be used for a considerable reduction in the cycle time.

Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnungen erläutert, die ein vorteilhaftes Ausführungsbeispiel veranschaulichen. Es zeigen:

  • Fig. 1 eine schematische Seitenansicht der Maschine und
  • Fig. 2 bis 5 Teilansichten gemäß Fig. 1 in aufeinanderfolgenden Funktionsstadien.
The invention is explained in more detail below with reference to the drawings which illustrate an advantageous embodiment. Show it:
  • Fig. 1 is a schematic side view of the machine and
  • 2 to 5 partial views according to FIG. 1 in successive functional stages.

Die Umhüllungs-Maschineneinheit 1 weist ein Maschinengestell auf, dessen dem Betrachter zugewendeteter Seitenteil 2 von den durchgezogenen Linien 3 umgrenzt ist und auf Rädern 14 ruht, die ggf. arretierbar sind. Der dem Betrachter abgewendete Seitenteil des Maschinengestells hat im wesentlichen dieselbe Gestalt. Zwischen den beiden Seitenteilen 2 des Maschinengestells, die durch nicht dargestellte Gestellteile starr miteinander verbunden sind, ist als Einlauf-Flachförderer ein Förderband 5 mit Umlenkwalzen 6, 7 vorgesehen, dessen Förderfläche horizontal ist und deren Förderrichtung mit der Pfeilrichtung übereinstimmt. Im oberen und unteren Bereich des Maschinengestells ist je eine Lagerung 8 für eine Folienrolle 9 vorgesehen, deren Bahnen über eine bekannte Walzenanordnung 10 zur Bildung eines Folienvorhangs 11 zusammengeführt und miteinander verbunden sind, der vertikal unmittelbar hinter dem Förderband 5 quer zur Förderrichtung des Förderbands angeordnet ist. Ein Balken 12 mit Schweiß- und Trennvorrichtung ist innerhalb des Maschinengestells vertikal beweglich (siehe Pfeil) geführt und mit einer entsprechenden Antriebseinrichtung versehen. Ferner ist eine Steuereinrichtung 13 für den Balkenantrieb vorhanden. In Fig. 1 ist der Balken in seiner Ruhestellung dargestellt. Vertikal, d.h. in Führungsrichtung unterhalb des Balkens ist ortsfest innerhalb des Maschinengestells der Schweißgegenbalken 14 angeordnet, mit dem der Schweißbalken 12 beim Trennschweißen zusammenwirkt. Der Schweißgegenbalken 14 ist zweckmäßigerweise innerhalb des Maschinengestells der Umhüllungs-Maschineneinheit gehalten, kann aber ggf. auch an der Umreifungs-Maschineneinheit vorgesehen sein.The wrapping machine unit 1 has a machine frame, the side part 2 facing the viewer is delimited by the solid lines 3 and rests on wheels 14, which can be locked if necessary. The side part of the machine frame facing away from the viewer has essentially the same shape. Between the two side parts 2 of the machine frame, which are rigidly connected to one another by frame parts (not shown), a conveyor belt 5 with deflection rollers 6, 7 is provided as a flat infeed conveyor, the conveying surface of which is horizontal and the direction of conveyance corresponds to the direction of the arrow. In the upper and lower area of the machine frame, a bearing 8 is provided for a film roll 9, the tracks of which are brought together and connected to one another via a known roller arrangement 10 to form a film curtain 11, which is arranged vertically directly behind the conveyor belt 5 transversely to the conveying direction of the conveyor belt . A bar 12 with welding and cutting device is vertically movable within the machine frame (see arrow) and provided with a corresponding drive device. There is also a control device 13 for the beam drive. In Fig. 1 the bar is shown in its rest position. Vertical, i.e. In the guide direction below the bar, the welding counter bar 14, with which the welding bar 12 interacts during the separation welding, is arranged in a stationary manner within the machine frame. The welding counter bar 14 is expediently held within the machine frame of the wrapping machine unit, but can also be provided on the strapping machine unit if necessary.

Die Umreifungs-Maschineneinheit 14 weist ein Maschinengestell 15 auf, das von der Linie 16 umgrenzt ist, die teilweise im Bereich der Verdeckung durch den Seitenteil des Maschinengestells 2 gestrichelt angedeutet ist. Die Umreifungs-Maschineneinheit ruht auf Rädern 17 und ist teilweise von den Seitenteilen 2 der Umhüllungs-Maschineneinheit seitlich umfaßt. Dies hat einerseits den Vorteil, daß die Umhüllungs-Maschineneinheit eine für ihre Stabilität hinreichende Standlänge besitzt und daß zum anderen die Lage der Umreifungs-Maschineneinheit seitlich gegenüber der Umhüllungs-Maschineneinheit hinreichend genau festgelegt wird.The strapping machine unit 14 has a machine frame 15 which is delimited by the line 16, which is partially in the area of concealment by the side part of the Machine frame 2 is indicated by dashed lines. The strapping machine unit rests on wheels 17 and is partially surrounded laterally by the side parts 2 of the wrapping machine unit. On the one hand, this has the advantage that the wrapping machine unit has a sufficient standing length for its stability and, on the other hand, that the position of the strapping machine unit is fixed sufficiently precisely laterally with respect to the wrapping machine unit.

Die Umreifungs-Maschineneinheit 14 weist oberseitig zwei aufeinanderfolgende, einen Zwischenraum 18 einschließende Förderbänder 19 und 20 auf, die den Auslauf-Flachförderer bilden und deren Förderfläche horizontal und in derselben Höhe ist wie diejenige des Förderbands 5. Oberhalb der Förderbänder 19, 20, und zwar im Bereich des Zwischenraums 18 befindet sich eine Brücke 21, die zwei Preßstempel 22 aufweist, die in der in Fig. 1 gezeigten Ruhestellung sich außerhalb des Förderwegs der zu verpackenden Zeitungsstapel befinden und sich quer über diesen hinweg erstrecken. Sie sind in nicht dargestellten Führungen innerhalb der Brücke 21 vertikal parallel zu sich selbst bewegbar. Für ihre nicht gezeigten Antriebseinrichtungen ist eine Steuereinrichtung 23 vorgesehen. In Förderrichtung hinter der Brücke 21 ist eine Anschlageinrichtung 24 vorgesehen, die derart gesteuert ist, daß sie in einer Stellung dem zu verpackenden Stapel den Förderweg versperrt und ihn ggf. dabei ausrichtet, und in einer anderen Stellung den Förderweg freigibt.The strapping machine unit 14 has on the top two successive conveyor belts 19 and 20 including an intermediate space 18, which form the discharge flat conveyor and whose conveying surface is horizontal and at the same height as that of the conveyor belt 5. Above the conveyor belts 19, 20, specifically in the area of the intermediate space 18 there is a bridge 21 which has two press rams 22 which, in the rest position shown in FIG. 1, are located outside the conveying path of the stack of newspapers to be packed and extend across them. In guides, not shown, they can be moved vertically parallel to themselves within the bridge 21. A control device 23 is provided for their drive devices, not shown. In the conveying direction behind the bridge 21, a stop device 24 is provided which is controlled in such a way that it blocks the conveying path in one position and, if necessary, aligns it with the stack to be packed, and releases the conveying path in another position.

Zusätzlich zu der Umfassung der Umreifungs-Maschineneinheit durch das Gestell der Umhüllungs-Maschineneinheit oder statt dessen können formschlüssige Verbindungen vorgesehen sein, die einen korrekten Anschluß der Förderwege und die örtliche Abstimmung der Funktionsteile sicherstellen. Ferner sind die beiden Maschineneinheiten mit einer Steuerungsverbindung versehen, die dafür sorgt, daß ihre Funktionen zeitlich so aufeinander abgestimmt erfolgen, wie dies in der folgenden Funktionsbeschreibung erläutert ist.In addition to or instead of encircling the strapping machine unit by the frame of the wrapping machine unit, form-fitting connections can be provided which ensure correct connection of the conveying paths and the local connection Ensure coordination of the functional parts. Furthermore, the two machine units are provided with a control connection which ensures that their functions are coordinated with one another in time, as is explained in the following functional description.

Gemäß Fig. 1 gelangt zunächst ein zu verpackender Zeitungsstapel 25 in Pfeilrichtung von einem nicht dargestellten Förderer her auf das Förderband 10. Wenn die Förderbänder 19, 20 noch nicht frei sind oder der Balken 12 sich noch nicht in seiner Ruhestellung befindet, wird das Förderband 10 angehalten, bis die Bedingungen zur Weiterförderung erfüllt sind. Der Stapel gelangt dann in die Stellung gemäß Fig. 2 auf den Förderbändern 19, 20, und zwar in die durch den Anschlag 24 definierte Stellung, in welcher der Förderbandzwischenraum 18 und die Brücke 21 etwa mittig zum Stapel liegen. Bei der Bewegung aus der Stellung gemäß Fig. 1 in diejenige gemäß Fig. 2 nimmt der Stapel den Folienvorhang 11 mit, so daß er von dem Folienband auf seiner Unterseite, der in Förderrichtung vorne liegenden Seite und der Oberseite umhüllt ist.1, a stack of newspapers 25 to be packed first reaches the conveyor belt 10 from a conveyor (not shown) when the conveyor belts 19, 20 are not yet free or the bar 12 is not yet in its rest position, the conveyor belt 10 stopped until the conditions for further funding are met. The stack then arrives in the position shown in FIG. 2 on the conveyor belts 19, 20, specifically in the position defined by the stop 24, in which the conveyor belt gap 18 and the bridge 21 are located approximately in the middle of the stack. When moving from the position according to FIG. 1 into that according to FIG. 2, the stack takes the film curtain 11 with it, so that it is encased by the film strip on its underside, the side lying in the conveying direction and the top side.

Anschließend fährt gemäß Fig. 3 das Preßstempelpaar 22 nieder, der Zeitungsstapel wird zusammengedrückt und mit einem Band 26 quer zur Förder- und Folienrichtung umreift. Anschließend fährt der Schweißbalken 12 nieder, rafft den Folienvorhang 11 auf der in Förderrichtung hinten liegenden Seite des Stapels zusammen und verschweißt ihn, wie dies in Fig. 4 dargestellt ist. Währenddessen wird der Stapel zusammengedrückt gehalten, und zwar durch das in Preßstellung befindliche Stempelpaar 22 oder die Umreifung 26. Jedenfalls muß in dem Augenblick, in welchem der Balken die Schweißstellung wieder nach oben verläßt, der Stapel durch eines dieser beiden Organe im komprimierten Zustand gehalten sein.3, the pair of press rams 22 moves down, the newspaper stack is compressed and strapped with a band 26 transversely to the conveying and film direction. The welding bar 12 then moves down, gathers the film curtain 11 on the side of the stack located at the rear in the conveying direction and welds it, as is shown in FIG. 4. In the meantime, the stack is kept compressed, namely by the pair of punches 22 in the pressing position or the strapping 26. In any case, at the moment when the bar is the Leaves welding position again upwards, the stack must be kept in the compressed state by one of these two organs.

Anschließend kann der verpackte und umschnürte Stapel 25 seine Förderbewegung fortsetzen, indem die Förderbänder 19, 20 eingeschaltet und/oder der Anschlag 24 gelöst wird.The packaged and tied stack 25 can then continue its conveying movement by switching on the conveyor belts 19, 20 and / or releasing the stop 24.
