Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen von (quaderförmigen) Packungen aus mindestens einem Zuschnitt aus faltbarem Verpackungsmaterial, wie Papier, (dünnem) Karton oder dergleichen, mit einem Leimaggregat mit mindestens einer Leimdüse zum Auftragen von Leim auf Packungsteile, insbesondere auf Faltlappen.The invention relates to a device for producing (cuboid) packs from at least one blank foldable packaging material, such as paper, (thin) cardboard or the like, with a glue unit with at least one glue nozzle for applying glue to package parts, especially on Folding rag.

Bei der Herstellung von Packungen aus durch Verleimen miteinander verbundenen Packungsteilen, insbesondere Faltlappen, werden zunehmend Leimaggregate eingesetzt, die berührungslos Leimportionen, insbesondere Leimpunkte auf die Verpackungszuschnitte übertragen. Derartige Leimdüsen bedürfen einer besonderen Behandlung bei zeitweiligem Stillstand der Verpackungsmaschine. Betriebsunterbrechungen treten in der Praxis bei allen Verpackungsmaschinen auf, auch bei solchen für die Fertigung von Zigarettenpackungen. Bei den Leimdüsen besteht die Gefahr, daß diese durch Aushärten des Leims beim Wiederanfahren der Verpackungsmaschine nicht mehr betriebsbereit sind, insbesondere durch Zusetzen der Düsen. When making packs by gluing them together connected pack parts, especially folding flaps glue aggregates are increasingly used, the contactless glue portions, especially glue spots on the packaging blanks transfer. Such glue nozzles require a special one Treatment when the packaging machine is temporarily at a standstill. Business interruptions occur in practice for everyone Packaging machines, including those for manufacturing of cigarette packs. With the glue nozzles there is a risk that by curing the glue when restarting the packaging machine is no longer operational, in particular by clogging the nozzles.

Bekannt ist eine Vorrichtung (EP 0 647 562 A1), bei der ein Leimaggregat mit Leimdüsen eingesetzt wird zum Aufbringen von punktförmigen Leimbildern auf Faltlappen von Zuschnitten. Das Leimaggregat ist von Hand aus einer Arbeits- bzw. Leimstellung herausnehmbar und als separate Einheit in eine Halterung einer Wartungsstation einsetzbar. Im Bereich derselben können notwendige Wartungsarbeiten an dem Leimaggregat durchgeführt werden. Hierzu gehört auch, dass das Leimaggregat in der Wartungsstation unter Betriebsbedingungen erprobt wird, wobei Leimportionen von einem Sammelbehälter aufgenommen werden. Die Wartungsstation ist entfernt von der Arbeits- bzw. Beleimungsstation angeordnet.A device is known (EP 0 647 562 A1) in which a Glue unit with glue nozzles is used to apply punctiform glue pictures on folding flaps of blanks. The Glue unit is manually from a working or glue position removable and as a separate unit in a holder Maintenance station can be used. In the area of the same can be necessary Maintenance work on the glue unit are carried out. This also includes that the glue unit in the maintenance station is tested under operating conditions, with glue portions be picked up by a collecting container. The maintenance station is removed from the work or gluing station arranged.

IT 1278185 (Anmeldung Nr BO 95 A000204, Veröffentlicht am 11. November 1996) offenbart ein feststehend positioniertes Leimaggregat, unter welches eine leimauffangvorrichtung bewegbar ist.IT 1278185 (Registration No. BO 95 A000204, Published on November 11, 1996) a fixedly positioned glue unit, under which a glue collecting device is movable.

Der Erfindung liegt die Aufgabe zugrunde, bei Verpackungsmaschinen mit Leimdüsen aufweisenden Leimaggregaten sicherzustellen, dass bei zeitweiliger Betriebsunterbrechung der Verpackungsmaschine das Leimaggregat bzw. die Leimdüsen gleichwohl betriebsbereit bleiben. The invention has for its object in packaging machines ensure with glue units having glue nozzles, that if the packaging machine is temporarily shut down the glue unit or the glue nozzles nevertheless remain operational.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Vorrichtung durch folgende Merkmale gekennzeichnet:

  • a) das Leimaggregat ist an einem Stellgetriebe angebracht,
  • b) bei Unterbrechung des Verpackungsprozesses ist das Leimaggregat durch das Stellgetriebe aus einer den Packungen bzw. Zuschnitten benachbarten Arbeits- bzw. Beleimungsstellung herausbewegbar in eine Wartestellung,
  • c) das Leimaggregat bzw. dessen Leimdüsen sind in der Wartestellung von Zeit zu Zeit betätigbar, wobei von dem Leimaggregat bzw. den Leimdüsen abgegebene Leimportionen von einer Auffangvorrichtung aufgefangen werden,
  • d) in der Wartestellung sind die Leimdüsen in einer aufrechten Stellung positioniert.
  • To achieve this object, the device according to the invention is characterized by the following features:
  • a) the glue unit is attached to an actuating gear,
  • b) if the packaging process is interrupted, the gluing unit can be moved out of a working or gluing position adjacent to the packs or blanks into a waiting position,
  • c) the glue unit or its glue nozzles can be actuated from time to time in the waiting position, glue portions dispensed by the glue unit or the glue nozzles being collected by a collecting device,
  • d) in the waiting position, the glue nozzles are positioned in an upright position.
  • Der Erfindungsgedanke besteht demnach darin, bei Betriebsunterbrechung der Verpackungsmaschine die Tätigkeit der Leimdüsen gleichwohl aufrechtzuerhalten, wenn auch mit reduzierter Taktzahl. Zu diesem Zweck werden die Leimdüsen aus einer Arbeits- bzw. Beleimungsstelle in unmittelbarer Nachbarschaft zu den Packungen herausbewegt und in einer entfernten Wartestellung von Zeit zu Zeit durch Abgabe von Leimportionen betätigt. Ein Aushärten des Leims im Bereich der Düsen wird dadurch vermieden.The idea of the invention is therefore in the event of business interruption the packaging machine the activity of the glue nozzles to be maintained, albeit with reduced Number of bars. For this purpose, the glue nozzles are removed from a working or gluing point in the immediate vicinity the packs moved out and in a distant waiting position operated from time to time by dispensing glue portions. This prevents the glue from hardening in the area of the nozzles.

    Das Leimaggregat mit vorzugsweise mehreren nebeneinander angeordneten Leimdüsen ist an einem besonderen Stellgetriebe angeordnet, vorzugsweise in Gestalt eines Vier-Gelenk-Getriebes. Dieses ermöglicht eine besondere Bewegungscharakteristik für das Leimaggregat, nämlich aus einer schrägen Arbeits- bzw. Beleimungsstellung der Leimdüsen in eine aufrechte Position derselben, seitlich versetzt. In dieser vom Faltrevolver entferntliegenden Wartestellung wird das Leimaggregat durch zeitweiliges, insbesondere taktweises Betätigen der Leimdüsen in funktionsfähigem Zustand gehalten. Die abgegebenen Leimportionen werden beispielsweise durch eine Wanne aufgefangen. Bei erneuter Inbetriebnahme der Verpackungsmaschine wird das Leimaggregat in die Arbeits- bzw. Beleimungsstellung zurückbewegt.The glue unit preferably with several arranged side by side Glue nozzle is arranged on a special actuator, preferably in the form of a four-bar gearbox. This enables a special movement characteristic for the glue unit, namely from an oblique working or gluing position the glue nozzles in an upright position, laterally offset. In this remote from the folding turret The glue unit is put on hold by temporary in particular cyclical actuation of the glue nozzles in functional Condition kept. The glue portions delivered are caught, for example, by a tub. When renewed The glue unit is put into operation of the packaging machine moved back to the working or gluing position.

    Eine weitere Besonderheit der Erfindung besteht darin, daß das Leimaggregat (zusätzlich) in eine Wartungsstellung bewegt werden kann. Diese Position des Leimaggregats ist so gewählt, daß der Zugang zu den einzelnen Leimdüsen zur Durchführung von Reinigungs-, Wartungs- und eventuell Testarbeiten erleichtert ist. Vorzugsweise wird hierzu das Leimaggregat durch eine Linearführung in achsparalleler Richtung zum Faltrevolver verschoben.Another special feature of the invention is that Glue unit (additional) to be moved into a maintenance position can. This position of the glue unit is chosen so that access to the individual glue nozzles for cleaning, Maintenance and possibly test work is made easier. For this purpose, the glue unit is preferably guided by a linear guide shifted in the axis-parallel direction to the folding turret.

    Weitere Einzelheiten der Erfindung beziehen sich auf die Lagerung und Betätigung des Leimaggregats sowie auf die Anordnung einer Auffangwanne. Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigt:

    In den Zeichnungen ist ein bevorzugtes Anwendungsbeispiel gezeigt, nämlich die Herstellung von Zigarettenpackungen des Typs Weichbecher. Bei diesem Verpackungstyp werden Zuschnitte 10 aus Papier oder ähnlichem Verpackungsmaterial zu einer becherförmigen Umhüllung als Teil der Packung gefaltet. Hierzu dient ein Faltrevolver 11, von dem in den Zeichnungen lediglich ein Ausschnitt schematisch gezeigt ist. Der Faltrevolver kann beispielsweise wie gemäß DE 35 45 884 ausgebildet sein.A preferred application example is shown in the drawings, namely the manufacture of cigarette packs of the type Soft cup. With this type of packaging, blanks 10 are made Paper or similar packaging material into a cup-shaped Envelope folded as part of the pack. This is what a Folding turret 11, only a section of which in the drawings is shown schematically. The folding turret can, for example as designed according to DE 35 45 884.

    Am äußeren Umfang des Faltrevolvers 11 sind mehrere verteilt angeordnete, im Querschnitt rechteckige Faltdorne 12 angeordnet. Diese übernehmen jeweils einen Zuschnitt 10. Auf dem Faltdorn 12 wird der Zuschnitt zum Becher gefaltet. In einem ersten Faltschritt (Fig. 1, Fig. 2) wird der Zuschnitt 10 U-förmig um den querliegenden Faltdorn 12 herumgelegt, so daß auf der in Transportrichtung rückwärtigen Seite ein Innenlappen 13 und ein Außenlappen 14 gebildet sind. Zur Verbindung derselben wird auf die in Radialrichtung nach außen gekehrte Seite des Innenlappens 13 Leim aufgetragen. Nach Umfalten des mit Leim versehenen Innenlappens 13 wird der Außenlappen 14 außen gegen diesen gefaltet und durch den Leim mit dem Innenlappen 13 verbunden.Several are distributed on the outer circumference of the folding turret 11 arranged, in cross section rectangular folding mandrels 12 arranged. These each take a cut 10. On the folding mandrel 12 the blank is folded into a cup. In a first Folding step (Fig. 1, Fig. 2), the blank 10 is U-shaped the transverse folding mandrel 12 folded so that on the in Transport direction rear side an inner tab 13 and a Outer lobes 14 are formed. To connect the same is on the radially outward-facing side of the inner lobe 13 glue applied. After folding over the glued one Inner lobe 13, the outer lobe 14 is against this outside folded and connected by the glue to the inner tab 13.

    Zum Aufbringen des Leims auf den Innenlappen 13 dient ein Leimaggregat 15. Dieses ist ortsfest am Außenumfang des Faltrevolvers 11 positioniert, und zwar außerhalb der Bewegungsbahn der Faltdorne 12, jedoch unmittelbar benachbart zu diesen. Während der vorzugsweise kontinuierlichen Drehbewegung des Faltrevolvers 11 wird Leim auf die nach außen gekehrte Seite der Innenlappen 13 aufgebracht.A is used to apply the glue to the inner tabs 13 Glue unit 15. This is stationary on the outer circumference of the folding turret 11 positioned, namely outside the path of movement the folding mandrels 12, but immediately adjacent to them. While the preferably continuous rotary movement of the folding turret 11 is glue on the outward side of the inner tabs 13 applied.

    Bei dem vorliegenden Ausführungsbeispiel werden Leimpunkte, also punktförmig gestaltete Leimbereiche auf den Innenlappen 13 aufgebracht. Vorzugsweise handelt es sich dabei um eine in Längsrichtung des Innenlappens 13 verlaufende Reihe von mehreren nebeneinanderliegenden Leimpunkten. Bei dem vorliegenden Ausführungsbeispiel werden sieben Leimpunkte auf den Faltlappen übertragen.In the present exemplary embodiment, glue dots, that is, punctiform glue areas on the inner tabs 13 upset. It is preferably an in Longitudinal direction of the inner tab 13 extending series of several adjacent glue points. In the present Embodiment are seven glue points on the folding flap transfer.

    Das Leimaggregat 15 besteht zu diesem Zweck aus mehreren nebeneinander angeordneten Leimdüsen 16. Jede der in Axialrichtung des Faltrevolvers 11 bzw. in Längsrichtung des Innenlappens 13 nebeneinanderliegenden Leimdüsen 16 überträgt einen Leimpunkt auf den Innenlappen 13. Bei dem genannten Beispiel des Leimbildes sind demnach sieben Leimdüsen 16 als Einheit nebeneinander positioniert (Fig. 3).For this purpose, the glue unit 15 consists of several side by side arranged glue nozzles 16. Each of the axially of the folding turret 11 or in the longitudinal direction of the inner tab 13 adjacent glue nozzles 16 transmits one Glue point on the inner lobe 13. In the example mentioned The glue pattern is therefore seven glue nozzles 16 side by side as a unit positioned (Fig. 3).

    Die Leimdüsen sind in einer Arbeits- bzw. Beleimungsstellung gemäß Fig. 1 unmittelbar benachbart zur Bewegungsbahn der Zuschnitte 10 positioniert. Aufgrund der verpackungstechnischen Vorgaben ist das Leimaggregat 15 versetzt zu einer (gedachten) vertikalen Mittelebene des Faltrevolvers 11 positioniert. Damit der Leim durch die Leimdüsen 16 in senkrechter Richtung zur Ebene des Innenlappens 13 übertragen wird, sind die Leimdüsen 16 in einer schrägen Ebene bzw. mit schräggerichteten Achsen positioniert (Fig. 1).The glue nozzles are in a working or gluing position 1 immediately adjacent to the movement path of the blanks 10 positioned. Due to the packaging technology The glue unit 15 is offset from an (imaginary) vertical center plane of the folding turret 11 positioned. In order to the glue through the glue nozzles 16 in the vertical direction to Level of the inner lobe 13 is transferred, the glue nozzles 16 in an inclined plane or with inclined axes positioned (Fig. 1).

    Bei Betriebsunterbrechung der Verpackungsmaschine, also bei zeitweiligem Stillstand des Faltrevolvers 11 oder bei fehlenden Zuschnitten 10 auf den Faltdornen 12 wird das Leimaggregat 15 aus der Arbeits- bzw. Beleimungsstellung gemäß Fig. 1 herausbewegt in eine vom Faltrevolver 11 entferntliegende Wartestellung gemäß Fig. 2. In dieser Wartestellung wird die Betriebsbereitschaft bzw. die Funktionsfähigkeit des Leimaggregats 15 aufrechterhalten. Zu diesem Zweck wird das Leimaggregat 15 von Zeit zu Zeit betätigt durch Abgabe von Leimportionen durch die Leimdüsen 16. Diese arbeiten demnach wie beim Beleimungsprozeß, wobei die Anzahl der Arbeitstakte des Leimaggregats 15 gegenüber dem ordnungsgemäßen Arbeitsablauf reduziert sein kann. Jedenfalls wird durch diesen Blindbetrieb des Leimaggregats 15 die Funktionsfähigkeit desselben, nämlich der Leimdüsen 16, bis zur Wiederaufnahme des Betriebs der Verpackungsmaschine erhalten.When the packaging machine is interrupted, i.e. at temporary standstill of the folding turret 11 or in the absence of The glue unit 15 is cut 10 on the folding mandrels 12 from the working or gluing position according to FIG. 1 moved out into a waiting position remote from the folding turret 11 2. In this waiting position, the operational readiness or the functionality of the glue unit 15 maintained. For this purpose the glue unit 15 operated from time to time by dispensing portions of glue through the glue nozzles 16. These therefore work as in the gluing process, where the number of work cycles of the glue unit 15 reduced compared to the proper workflow can be. In any case, this blind operation of the Glue unit 15 the functionality of the same, namely the Glue nozzles 16 until the packaging machine resumes operation receive.

    Die vom Leimaggregat 15 abgegebenen Leimportionen werden aufgefangen, und zwar durch eine Auffangwanne 17. Diese ist ortsfest positioniert, nämlich in der Wartestellung des Leimaggregats 15 gemäß Fig. 2 unterhalb der Leimdüsen 16.The glue portions delivered by the glue unit 15 are collected, by a drip pan 17. This is stationary positioned, namely in the waiting position of the glue unit 15 below the glue nozzles 16.

    In der Wartestellung des Leimaggregats 15 sind die Leimdüsen 16 in einer aufrechten Stellung positioniert (Fig. 2), um die Aufrechterhaltung des Betriebs zu erleichtern. Darüber hinaus sind die Leimdüsen 16 etwas seitlich versetzt gegenüber der Arbeits-bzw.
