Abstract

Known machines for gluing folding cartons for the production of folding cartons from blanks have devices for transporting the blanks through the machine which comprise lower conveying belts (7) and upper conveying belts (14), the lower conveying belts (7) being mounted on a roller cheek (8) which can be transversally moved by a drive and the upper conveying belts (14) being mounted on a transversally mobile roller track. The invention provides for an endless rope or band-like element, preferably a wire rope (21), to be arranged in the machine such that it is able to move freely in its longitudinal direction and forms two strands, so that a loop (21) below the conveying plane of the blanks extends cross-wise across the width of the machine and a second loop (22) which is parallel to the first loop (21) above the machine extends cross-wise across the width of the machine. The roller cheek (8) is fixedly joined to one strand of the lower loop (21) and the roller track (15) can be clamped to the other strand of the upper loop (22). In this way the roller track (15) is entrained during a transverse movement of the roller cheek (8).

Stand der TechnikState of the art

Faltschachtelklebemaschinen zur Herstellung von Faltschachteln aus Zuschnitten weisen bekannterweise mehrere Bearbeitungsstationen auf, die von den Zuschnitten/Schachteln nacheinander durchlaufen werden:Folding box gluing machines for the production of folding boxes from blanks are known to have multiple processing stations by the blanks / boxes be run through one after the other:

Die Zuschnitte werden zunächst in einem Einleger mit hoher Geschwindigkeit aus einem Stapel nacheinander abgezogen und einzeln entweder direkt einer Faltstation oder zunächst einem sogenannten Vorbrecher zugeführt, der der Faltstation vorgeschaltet ist. In der Faltstation werden die mit einem Klebestreifen versehenen Zuschnitteile zur Herstellung einer Klebeverbindung um 180° umgelegt, also gefaltet. im Vorbrecher werden die Faltlappen vor dem Auftragen von Klebstoff vor- und zurückgefaltet, damit die entsprechenden Längsrillinien durch Knicken um 180° weich und geschmeidig gemacht werden.The blanks are first made in a feeder at high speed peeled off one after the other and individually either directly from a folding station or first fed to a so-called primary crusher, the folding station is connected upstream. In the folding station they are provided with an adhesive strip Cut parts folded through 180 ° to create an adhesive connection, i.e. folded. in the primary crusher, the folding flaps are pre- and pre-applied folded back so that the corresponding longitudinal creasing lines are soft by 180 ° and be made supple.

Im Anschluß an die Faltstation folgt üblicherweise eine sogenannte Überleitstation, in der die Schachteln gezählt, markiert und - falls schadhaft - ausgeschleust werden können. Danach folgt eine Sammel- und Preßeinrichtung, in der zunächst ein Schuppenstrom aus gefalteten Zuschnitten gebildet wird, der anschließend zwischen Preßbändern für einige Zeit unter Druck gehalten wird, damit die beiden Zuschnitteile an der Klebenaht verbunden werden. Als Abschluß folgt üblicherweise eine Packeinrichtung, in der die flachliegend gefalteten Faltschachteln in Umkartons gepackt werden.The folding station is usually followed by a so-called transfer station, in who counted the boxes, marked them and, if they were defective, removed them can. This is followed by a collection and pressing device, in the first one Scale stream is formed from folded blanks, which then between Press belts are kept under pressure for some time so the two cut pieces be connected at the adhesive seam. A packing facility usually follows at the end, in which the flat folded folded boxes are packed in cardboard boxes become.

Der Transport der Zuschnitte durch die einzelnen Bearbeitungsstationen erfolgt mittels oberer und unterer Förderriemen, die jeweils auf ihrer den Zuschnitten abgewandten Seite abgestützt sind. In der Regel werden über die Maschinenbreite zwei Paare von schmalen Riemen eingesetzt, die zur Anpassung auf verschiedene Schachtelformate für die optimale Berührungslinie mit den Zuschnitten quer positioniert werden können. Bekannterweise sind die oberen Förderriemen mit ihrer Befestigung anhebbar, damit bei einem Stau in der Maschine die Schachteln entfernt werden können.The blanks are transported through the individual processing stations by means of upper and lower conveyor belts, each on their side facing away from the blanks Are supported. Usually two pairs of are across the machine width narrow straps used to adapt to different box formats can be positioned transversely with the blanks for the optimal line of contact. As is known, the upper conveyor belts can be raised with their fastening, so in the event of a jam in the machine, the boxes can be removed.

Es ist bekannt, die Förderstrecken aus einzelnen Segmenten aufzubauen. Jeder der unteren Transportriemen eines Segments ist in einer sogenannten Rollenwange gelagert, die sich über die gewünschte Förderstrecke erstreckend angeordnet ist und an ihrer Oberseite über ihre Länge eine Reihe von schmalen Rollen enthält, die den oberen Trum des Förderriemens an seiner Unterseite abstützen. Jeder obere Förderriemen eines Segments ist an einer sogenannten Rollenschiene gelagert, die sich ebenfalls in Transportrichtung über die gewünschte Förderstrecke erstreckt und an ihrer Unterseite eine Reihe von Rollen aufweist, von denen die Oberseite der unteren Trums der Förderriemen abgestützt werden. Rollenwangen und Rollenschienen sind jeweils quer positionierbar, damit sie in der gewünschten Arbeitsposition unmittelbar übereinander angeordnet sind, um die Zuschnitte zwischen den fördernden Trums der Förderriemen zu halten und zu transportieren. Zumindest die Förderriemen der unten angeordneten Rollenwangen sind angetrieben. Die Förderriemen der zugehörigen oberen Rollenschienen sind entweder freilaufend gelagert oder-beispielsweise bei der Verarbeitung von dicken Zuschnitten aus Wellpappe - ebenfalls angetrieben, damit keine Markierungen auftreten. It is known to build the conveyor lines from individual segments. Everyone who lower conveyor belt of a segment is in a so-called roller cheek stored, which is arranged extending over the desired conveyor line and a series of narrow rolls containing the Support the upper run of the conveyor belt on its underside. Any top Conveyor belts of a segment are mounted on a so-called roller track also extends in the transport direction over the desired conveyor line and has on its underside a number of rollers, of which the top of the lower strands of the conveyor belts are supported. Roller cheeks and roller rails can be positioned transversely so that they are in the desired working position are arranged directly one above the other to cut the blanks between the conveying To hold and transport the belt of the conveyor belt. At least the conveyor belts the roller cheeks arranged below are driven. The conveyor belts of the Associated upper roller rails are either stored freely or, for example when processing thick blanks from corrugated cardboard - likewise driven so that no markings occur.

Bei den bekannten Faltschachtelklebemaschinen sind die Teile, an denen die oberen Rollenschienen befestigt sind, konstruktiv sehr aufwendig gestaltet, damit sie synchron zu den zugehörigen Rollenwangen quer positioniert und zugleich angehoben werden können.In the known folder gluer, the parts on which the upper Roller rails are attached, designed to be very complex, so that they positioned transversely to the associated roller cheeks and raised at the same time can be.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention

In Förderrichtung (von rechts nach links) beginnt die Faltschachtelmaschine mit einem Einleger 1, der die zu verarbeitenden Zuschnitte mit hoher Geschwindigkeit aus einem Stapel nacheinander abzieht und einzeln der nachfolgenden Bearbeitungsstation zuführt. Auf den Einleger 1 folgt ein Vorbrecher 2, der im vorliegenden Ausführungsbeispiel zweistufig ausgebildet ist. Der Vorbrecher 2 enthält Faltelemente, um Faltlappen vor und zurück zu falten, damit die entsprechenden Längsrillinien durch Knicken um 180° weich und geschmeidig gemacht werden. Die zweistufige Ausführungsform ermöglicht es, mehr Längs- und Querrillinien zu brechen und zusätzliche Faltungen durchzuführen. Bei bestimmten Schachtelformen werden auch bereits innerhalb des Vorbrechers Klebstoffauftragwerke angeordnet, um zusätzliche Klebestreifen in Längsrichtung aufzutragen. Auf den Vorbrecher 2 folgt als nächste Arbeitsstation die Faltstation 3, an deren Anfang ein Auftragwerk 4 für Klebstoff, üblicherweise für Leim, angeordnet ist. Das Klebstoffauftragwerk 4 enthält Leimdüsen oder Leimscheiben, von denen der Klebstoff streifenförmig auf die Zuschnitte aufgebracht wird. Anschließend werden die Faltlappen der Zuschnitte von Faltelementen gefaltet.In the direction of conveyance (from right to left) the folding box machine starts with a Insert 1 which cuts the blanks to be processed at high speed from one The stack is removed one after the other and individually from the subsequent processing station supplies. The feeder 1 is followed by a primary crusher 2, which in the present exemplary embodiment is designed in two stages. The primary crusher 2 contains folding elements in order Fold flaps back and forth so that the corresponding longitudinal crease lines go through Kinks by 180 ° can be made soft and smooth. The two-stage Embodiment enables more longitudinal and transverse creasing lines to be broken and perform additional folds. With certain box shapes, too already arranged within the primary crusher for additional Apply adhesive strips lengthways. The primary crusher 2 follows next Work station the folding station 3, at the beginning of which an applicator 4 for adhesive, usually for glue. The adhesive applicator 4 contains glue nozzles or glue discs, of which the adhesive strips on the blanks is applied. Then the folding flaps of the blanks of folding elements folded.

Die flachliegend gefalteten Schachteln werden anschließend einer Überleitstation 5 zugeführt, von der sie einer nachfolgend angeordneten Sammel- und Preßeinrichtung 6 übergeben werden. Beim Übergang von der Überleitstation 5 zur Sammel- und Preßeinrichtung 6 wird ein Schuppenstrom aus den gefalteten Schachteln hergestellt. Die Sammel- und Preßeinrichtung 6 weist Preßbänder auf, mittels deren die Klebenähte unter Druck gehalten werden, bis der Klebstoff sicher abgebunden ist.The flat folded boxes then become a transfer station 5 supplied, from which they are arranged in a downstream collecting and pressing device 6 are handed over. At the transition from the transfer station 5 to the collecting and Press device 6 produces a shingled stream from the folded boxes. The collecting and pressing device 6 has press belts, by means of which the adhesive seams be kept under pressure until the adhesive has set securely.

Beim Transport durch den Vorbrecher 2 und die Faltstation 3 werden die flachliegend gefalteten Zuschnitte zwischen oberen und unteren Förderriemen gehalten, wobei üblicherweise zwei Riemenpaare über die Maschinenbreite angeordnet sind, die sich in Förderrichtung aus einzelnen Segmenten aufbauen. Jedes der aus einem oberen und unteren Förderriemen bestehenden Riemenpaare eines Segments muß zur Einstellung der optimalen Angriffsposition an den sich ändernden Zuschnittsformaten querpositionierbar im Rahmen der Maschine gelagert sein. In Figur 2 sind der Aufbau eines Riemenpaares mit seiner Lagerung in der Maschine einschließlich der Mittel zur Querverstellung detailliert dargestellt:When transported through the primary crusher 2 and the folding station 3, they are lying flat folded blanks held between upper and lower belts, being Usually two pairs of belts are arranged across the machine width, which are in Build up the conveying direction from individual segments. Each of an upper and Lower conveyor belts existing belt pairs of a segment must be adjusted the optimal attack position on the changing blank formats can be positioned transversely be stored in the machine. In Figure 2 are the structure of a Belt pair with its storage in the machine including the means for Cross adjustment shown in detail:

Der untere Förderriemen 7 ist an einer sich in Förderrichtung erstreckenden Rollenwange 8 gelagert, die auf bekannte Weise im Maschinenrahmen aufgehängt und mittels Verstellspindeln querpositionierbar ist. Die in Figur 2 nicht dargestellten Verstellspindeln sind mit ihren Enden in den Seitenwänden 9, 10 der Klebemaschine befestigt. Sie sind mit einem Drehantrieb verbunden, der eine Querverschiebung der Rollenwange 8 bewirkt. An der Oberkante der Rollenwange 8 ist eine Reihe von Rollen 11 frei drehbar befestigt, von denen der obere Trum des Förderriemens 7 abgestützt wird. Der Förderriemen 7 ist endlos in sich geschlossen. Er wird zu Beginn und am Ende der Rollenwange 8 von Riemenscheiben 12, 13 umgelenkt, wobei die auslaufseitig umlenkende Riemenscheibe 13 zum Antreiben des Riemens 7 quer verschiebbar auf einer angetriebenen Welle sitzt, z. B. einer Vielkantwelle, die ebenfalls mit ihren Enden in den Seitenwänden 9, 10 der Maschine gelagert ist. Die Rollenwange 8 mit dem unteren Förderriemen 7 kann so zwischen den Seitenwänden 9, 10 querverschoben werden, um die gewünschte Arbeitsposition einzunehmen.The lower conveyor belt 7 is on a roller cheek extending in the conveying direction 8 stored, which is suspended in the machine frame in a known manner and can be positioned transversely by means of adjusting spindles. The not shown in Figure 2 Adjusting spindles are with their ends in the side walls 9, 10 of the gluing machine attached. They are connected to a rotary drive that causes a transverse displacement of the Roller cheek 8 causes. On the upper edge of the roller cheek 8 is a series of Rollers 11 are freely rotatable, of which the upper run of the conveyor belt 7th is supported. The conveyor belt 7 is closed endlessly. He will start and deflected at the end of the roller cheek 8 by pulleys 12, 13, the pulley 13 deflecting on the outlet side for driving the belt 7 transversely slidably sits on a driven shaft, e.g. B. a polygonal shaft, the is also supported with its ends in the side walls 9, 10 of the machine. The Roller cheek 8 with the lower conveyor belt 7 can thus between the side walls 9, 10 are moved laterally to take up the desired working position.

Der obere Förderriemen 14 ist an einer sogenannten Rollenschiene 15 gelagert, die am unteren Ende eines gabelförmigen Tragteils 16 befestigt ist. Der untere Trum des Förderriemens 14 wird an seiner Oberseite ebenfalls von Rollen abgestützt. Der obere Förderriemen 14 ist entweder frei umlaufend gelagert oder er ist ebenfalls angetrieben, dann allerdings gegensinnig zum unteren Förderriemen 7, damit sich die fördernden Trums beider Riemen 7, 14 in die gleiche Richtung bewegen.The upper conveyor belt 14 is mounted on a so-called roller rail 15, which on lower end of a fork-shaped support member 16 is attached. The lower strand of the Conveyor belt 14 is also supported on its top by rollers. The upper Conveyor belt 14 is either freely rotating or is also driven, then in opposite directions to the lower conveyor belt 7, so that the conveying strands of both belts 7, 14 move in the same direction.

Der obere Teil des Tragteils 16 der Rollenschiene 15 ist als Laufwagen 17 gestaltet, der an einem Tragbalken 18 aufgehängt ist. Der Tragbalken 18 erstreckt sich über die Maschinenbreite in einer gewissen Höhe oberhalb der Förderebene der Zuschnitte. Er ist mit seinen beiden Enden jeweils an einem seitlichen Ständer 19, 20 vertikal bewegbar befestigt. Die Ständer 19, 20 sind an den Seitenwänden 9, 10 der Maschine festgeschraubt. Durch diese Konstruktion ist der Laufwagen 17 mit der daran hängend befestigten Rollenschiene 15 frei querverschiebbar in der Maschine aufgehängt.The upper part of the support part 16 of the roller rail 15 is designed as a carriage 17, which is suspended from a support beam 18. The support beam 18 extends over the Machine width at a certain height above the conveying level of the blanks. He is vertical with its two ends each on a side stand 19, 20 movably attached. The stands 19, 20 are on the side walls 9, 10 of the Machine screwed. Due to this construction, the carriage 17 with the attached roller rail 15 freely movable in the machine suspended.

Damit die Zuschnitte sicher zwischen den beiden Förderriemen 7, 14 gehalten werden, muß die Rollenschiene 15 jeweils exakt oberhalb einer Rollenwange 8 angeordnet sein. Bei einer Änderung der Position müssen somit die Rollenwange 8 und die Rollenschiene 15 synchron verschoben werden. Dies erfolgt nach der Erfindung mit folgenden, konstruktiv sehr einfachen Mitteln: So that the blanks are held securely between the two conveyor belts 7, 14 the roller rail 15 must be exactly above a roller cheek 8 be arranged. If the position changes, the roller cheek 8 and the roller rail 15 are moved synchronously. This is done after the Invention with the following, structurally very simple means:

Ein in sich geschlossenes, also endloses band- oder seilförmiges Element, vorzugsweise ein Drahtseil 21, ist so zwischen den beiden Seitenplatten 9, 10 der Maschine in seine Längsrichtung frei bewegbar gespannt, daß eine Schlaufe 21 unterhalb der Förderebene der Zuschnitte im Bereich der Rollenwange 8 quer über die Maschinenbreite verläuft. Die zweite Schlaufe 22 am anderen Ende des Drahtseils verläuft parallel zur ersten Schlaufe 21 oberhalb der Förderebene, bevorzugt oberhalb der Rollenschiene 15 im Bereich des Laufwagens 17, quer über die Maschinenbreite. Zwischen der unteren Schlaufe 21 und der oberen Schlaufe 22 werden die beiden Stränge 23 des Drahtseils in einem seitlichen Ständer (Ständer 19) nach oben geführt. Wie aus Figur 2 ersichtlich, beginnt das doppelsträngig geführte Drahtseil an einer Umlenkrolle 24, die an der Innenseite einer Seitenwand (Seitenwand 10) frei drehbar gelagert ist. Eine erste untere Schlaufe 21 verläuft dann geradlinig unterhalb des Bereichs der Rollenwange 8 zu der anderen Seitenwand (Seitenwand 9). Dort werden beide Stränge 23 senkrecht nach oben umgelenkt und verlaufen innerhalb des Ständers 19 nach oben bis in den Bereich oberhalb des Tragbalkens 18. In dieser Höhe werden die beiden Stränge 23 in einen waagerechten Verlauf umgelenkt und verlaufen wieder waagerecht, die Schlaufe 22 bildend, zu der anderen Maschinenseite. Dort ist das Ende der Schlaufe 22 um Umlenkrollen geführt, die frei drehbar an dem Ständer 20 gelagert sind.A self-contained, that is, endless band-shaped or rope-shaped element, preferably a wire rope 21, is between the two side plates 9, 10 of the machine stretched freely in its longitudinal direction that a loop 21 below the Conveying plane of the blanks in the area of the roller cheek 8 across the machine width runs. The second loop 22 runs at the other end of the wire rope parallel to the first loop 21 above the conveying plane, preferably above the Roller rail 15 in the area of the carriage 17, across the machine width. Between the lower loop 21 and the upper loop 22, the two Strands 23 of the wire rope in a side stand (stand 19) led upwards. As can be seen from Figure 2, the double-stranded wire rope starts at one Deflection roller 24, which is freely rotatable on the inside of a side wall (side wall 10) is stored. A first lower loop 21 then runs in a straight line below the Area of the roller cheek 8 to the other side wall (side wall 9). There will be both strands 23 are deflected vertically upwards and run within the Stand 19 up to the area above the support beam 18. In this Height, the two strands 23 are deflected into a horizontal course and again run horizontally, forming the loop 22, to the other side of the machine. There, the end of the loop 22 is guided around deflection rollers, which are freely rotatable the stand 20 are stored.

Das Drahtseil 21, 22, 23 dient als Schleppseil für die obere Rollenschiene 15, um diese bei einer Querverstellung der Rollenwange 8 synchron mitzuschleppen. Dazu ist die Rollenwange 8 mit einem Strang der unteren Schlaufe 21 über ein laschenförmiges Element 25 verbunden, so daß bei einer Verstellung der Rollenwange 8 mittels des Sprindeltriebs dieser Strang in die entsprechende Richtung mitgezogen wird. Der Laufwagen 17 der Rollenschiene 15 weist eine Klemmeinrichtung 26 auf, mit der er an den anderen Strang der oberen Schlaufe 22 festgeklemmt werden kann. In festgeklemmtem Zustand bewegt sich der Laufwagen 17 mit der daran befestigten Rollenschiene 15 so synchron mit der Rollenwange 8. Er wird bei einer Querverschiebung der Rollenwange 8 in die entsprechende Richtung mitgezogen, ohne daß er einen eigenen Antrieb benötigt. The wire rope 21, 22, 23 serves as a tow rope for the upper roller rail 15 in order to carry them synchronously with a transverse adjustment of the roller cheek 8. Is to the roller cheek 8 with a strand of the lower loop 21 over a tab-shaped Element 25 connected so that when adjusting the roller cheek 8 by means of of the spindle drive this strand is pulled in the corresponding direction. The Carriage 17 of the roller rail 15 has a clamping device 26 with which it can be clamped to the other strand of the upper loop 22. In clamped state, the carriage 17 moves with the attached Roller rail 15 so synchronized with the roller cheek 8. It is in a transverse shift the roller cheek 8 pulled in the corresponding direction without it needs its own drive.

Bevorzugt ist der unterhalb der oberen Schlaufe 22 angeordnete Tragbalken 18 begrenzt vertikal bewegbar in den Ständern 19, 20 gelagert. Die vertikale Bewegbarkeit des Tragbalkens 18 mit den darauf aufgehängten Rollenschienen 15 ermöglicht es, einen vorbestimmten Abstand zwischen den fördernden Trums der beiden Förderriemen 7, 14 einzustellen. Zugleich können die Rollschienen 15 nach oben in eine Wartungsposition bewegt werden, bei der beispielsweise sich stauende Zuschnitte entfernt werden können. Bevorzugt erfolgt die vertikale Bewegung des Tragbalkens 18 mittels zweier Pneumatikzylinder, die jeweils in einem Ständer 19, 20 angeordnet den Tragbalken 18 nach oben gegen einen einstellbaren Anschlag drücken. Die gewünschte vertikale Position der Rollschienen 15 kann so über die verstellbaren Anschläge eingestellt werden.The supporting beam 18 arranged below the upper loop 22 is preferred limited vertically movable stored in the stands 19, 20. The vertical mobility of the support beam 18 with the roller rails 15 suspended thereon it, a predetermined distance between the conveying strands of the two Adjust conveyor belts 7, 14. At the same time, the roller rails 15 can be moved upwards a maintenance position is moved in which, for example, jamming Cuts can be removed. The vertical movement of the Support beam 18 by means of two pneumatic cylinders, each in a stand 19, 20th arranged the support beam 18 upwards against an adjustable stop to press. The desired vertical position of the roller rails 15 can thus over the adjustable stops.
