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 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 mit Presseinrichtung sowie eine Steuereinrichtung umfasst.The invention relates to a machine for wrapping an elastically compressible stack, in particular of publications and newspapers, in a foil band and for strapping the wrapped stack with a belt, which has a flat infeed conveyor for the stack, a conveyor table adjoining it, Devices for forming a film curtain passing through the intermediate space, a welding device arranged behind the film curtain for closing and welding off the band formed by the film curtain around a stack lying on the conveyor table, for closing and welding off the band formed by the film curtain around a stack lying on the conveyor table, and one with the strapping device interacting with the pressing device and a control device in the welding position lying on the conveyor table.

Es ist eine Maschine dieser Art bekannt (DE-A-19 63 531), in welcher auf den zu verpakkenden Zeitschriftenstapel eine erste Presseinrichtung wirkt, die vor dem Verschweissen der Umhüllung entfernt wird, und in der nach dem Umhüllen eine der Umreifungseinrichtung zugehörige zweite Presseinrichtung auf den Stapel einwirkt.A machine of this type is known (DE-A-19 63 531), in which a first press device acts on the stack of magazines to be packaged, which is removed before the wrapping is welded, and in the second press device associated with the strapping device after the wrapping acts on the stack.

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 having to replace the other 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 of creating a machine of the type mentioned at the outset which is adapted to the European production and maintenance requirements and is nevertheless 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, wobei die Steuerungseinrichtung (13, 23) so ausgebildet ist, dass die sich quer zur Förderrichtung über den Stapel erstreckende Presseinrichtung (22) den Stapel zusammenpresst, bevor die Banderole (11) auf der in Förderrichtung hinten liegenden Seite gerafft und geschlossen wird.The solution according to the invention consists in that the machine consists of two separate machine units that can be connected in terms of control, the first of which is the infeed flat 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 The control device (13, 23) is designed such that the pressing device (22), which extends across the stack transversely to the conveying direction, presses the stack together before the band (11) is gathered and closed on the side lying in the conveying direction.

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. Die der ersten Maschineneinheit zugeordneten Funktionen werden durchgeführt, wenn sich der Stapel in der zweiten Maschineneinheit befindet, wobei die Presseinrichtung der Umreifungsvorrichtung wirksam wird, bevor die Umhüllung geschlossen ist und obwohl dies verhindert, dass sie um den gesamten Stapel gleichmässig stramm gezogen werden kann. Die beiden Einheiten können von unterschiedlichen Herstellern stammen, die jeweils das Know-how der Umhüllungstechnik einerseits und der Umreifungstechnik andererseits beherrschen und auch jeweils die Wartung der von ihnen stammenden Maschinen ohne Rücksicht auf die andere durchführen können.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. The functions associated with the first machine unit are performed when the stack is in the second machine unit, with the strapping device press acting before the wrapper is closed and although this prevents it from being pulled evenly around the entire stack. The two units can come from different manufacturers, who each have the know-how of the wrapping technology on the one hand and the strapping technology on the other hand and can also carry out the maintenance of the machines they produce, regardless of the other.

Damit der funktionelle Übergang gewährleistet ist, sind die Maschineneinheiten zweckmässigerweise formschlüssig aneinander anschliessend ausgebildet.In order to ensure the functional transition, the machine units are expediently designed to be positively connected to one another.

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.According to a special feature of the invention, the control device can be designed such that the strapping takes place at the same time at the latest, but better before the banderole 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 that 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 in schematischer Darstellung ohne Berücksichtigung der tatsächlichen Kompressions- und Spannungsverhältnisse.
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 in a schematic representation without taking into account the actual compression and tension conditions.

Die Umhüllungs-Maschineneinheit 1 weist ein Maschinengestell auf, dessen dem Betrachter zugewendeter Seitenteil 2 von den durchgezogenen Linien 3 umgrenzt ist und auf Rädern 4 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 12' angeordnet, mit dem der Schweissbalken 12 beim Trennschweissen zusammenwirkt. Der Schweissgegenbalken 12' 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 of which is delimited by the solid lines 3 and rests on wheels 4 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 beam 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. Vertically, ie in the guide direction below the bar, the welding counter bar 12 'is arranged in a fixed position within the machine frame, with which the welding bar 12 interacts during the separation welding. The welding counter bar 12 '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 Verdekkung 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 indicated by dashed lines in the area of the covering by the side part of the machine frame 2. 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 length for its stability and, on the other hand, that the position of the strapping machine unit on the side relative to the wrapping machine unit is determined with sufficient accuracy.

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 punches 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 Steuerungsverbin- dung 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 coordination of the functional parts. Furthermore, the two machine units with a Steuerun are sverbin- g dung provided that ensures that their functions temporally matched to one another take place, as discussed in the following functional description.

Gemäss Fig. 1 gelangt zunächst ein zu verpakkender 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 packaged first arrives at the conveyor belt 10 from a conveyor (not shown) in the direction of the arrow. If 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 lie 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 band on its underside, the front side 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 stamps 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 shown in FIG. 4. In the meantime, the stack is kept compressed, namely by the pair of punches 22 in the press position or the strapping 26. In any case, at the moment when the bar leaves the welding position again upwards, the stack must be held in a 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 strapped stack 25 can then continue its conveying movement by switching on the conveyor belts 19, 20 and / or releasing the stop 24.
