Description

Die Erfindung betrifft ein Leimwerk für eine Etikettiermaschine, mit einem Leimtank, der mit Leim befüllbar ist, wobei der Leim auf eine Beleimungswalze des Leimwerks aufbringbar ist.The invention relates to a gluing unit for a labeling machine, with a glue tank which can be filled with glue, wherein the glue can be applied to a gluing roller of the gluing unit.

Die Erfindung betrifft auch eine Etikettiermaschine mit einem solchen Leimwerk.The invention also relates to a labeling machine with such a gluing unit.

Aus dem Stand der Technik sind Etikettiermaschinen und Beleimungsvorrichtungen etwa aus der DE 36 08 773 A1 bekannt. Die diesbezügliche Druckschrift bezieht sich auf eine Beleimungsvorrichtung für eine Etikettiermaschine mit einer insbesondere einen elastischen Mantel aufweisenden Leimwalze und einem sich mit einer insbesondere unelastischen Leimaufnahmefläche auf dem Mantel der Leimwalze abwälzenden Etikettenaufnahmeelement. Damit Fehletiketten, die vom Etikettenentnahmeelement nicht für die Etikettierung abgenommen worden sind, sich nicht vor einem Leimschaber stauen und die empfindliche Oberfläche der Leimwalze beschädigen, ist vorgesehen, dass die Oberfläche der Leimwalze als Reibfläche zum Zwecke eines mechanischen Abtrags von Etiketten ausgebildet ist und/oder die Haftfähigkeit des Mantels der Leimwalze und die Haftfähigkeit der Leimaufnahmefläche des Etikettenentnahmeelementes derart aufeinander abgestimmt sind, dass Fehletiketten von der Leimaufnahmefläche beim Abwälzen des Etikettenentnahmeelementes am Mantel der Leimwalze auf der Leimaufnahmefläche haften bleiben.Labeling machines and gluing devices are known from the state of the art, for example DE 36 08 773 A1 known. The relevant document relates to a gluing device for a labeling machine with a particular an elastic jacket having glue roller and a rolling in particular with a non-elastic glue receiving surface on the jacket of the glue roller label receiving element. To prevent mis-labels that have not been removed from the label removal element for labeling, do not accumulate in front of a glue scraper and damage the sensitive surface of the glue roller, it is provided that the surface of the glue roller is designed as a friction surface for the purpose of mechanical removal of labels and / or the adhesion of the jacket of the glue roller and the adhesiveness of the glue receiving surface of the label removal element are matched to one another such that defective labels from the glue receiving surface adhere to the surface of the glue removal surface during rolling of the label removal element on the glue receiving surface.

Eine ähnliche Vorrichtung, nämlich eine Rundum-Etikettiervorrichtung ist auch aus dem deutschen Gebrauchsmuster DE 20 2005 002 793 U1 der derzeitigen Anmelderin bekannt. Eine solche Etikettiermaschine ist zum Etikettieren von Behältern, wie Dosen, PET-Flaschen, Glasflaschen oder Büchsen mit Rundum-Etiketten mindestens aufweisend eine Behälterzufuhr, einen Behältertisch, eine Behälterabfuhr und mindestens ein Etikettieraggregat für Rundum-Etiketten, wobei das Etikettieraggregat aus mindestens einer Etikettenrolle, einer Etikettenzuführung, einer Schneideinrichtung, einem Greiferzylinder und mindestens einem Leitwerk besteht, ausgebildet. Die dortige Rundum-Etikettiervorrichtung ist dadurch gekennzeichnet, dass die Schneideinrichtung durch eine rotierende Vakuumwalze und ein rotierendes Trennelement gebildet wird, wobei das rotierende Trennelement an dessen Umfang mindestens ein Trennwerkzeug, insbesondere ein Schneidmesser, besitzt.A similar device, namely an all-around labeling device is also from the German utility model DE 20 2005 002 793 U1 known to the present applicant. Such a labeling machine is for labeling containers, such as cans, PET bottles, glass bottles or rifles with wrap-around labels at least comprising a container feed, a container table, a container removal and at least one labeling unit for wrap-around labels, the labeling unit comprising at least one label roll, a label feed, a cutting device, a gripper cylinder and at least one tail exists. The local all-around Etikettiervorrichtung is characterized in that the cutting device is formed by a rotating vacuum roller and a rotating separator, wherein the rotating Separating element on the circumference at least one cutting tool, in particular a cutting blade has.

Um ein Etikettenstück mit einem Leimstreifen versehen zu können, wird dabei ein Leimwerk eingesetzt. Das Leimwerk besteht aus einem Leimtank, einer Leimheizung, einer Leimleiste, einer Leimpumpe und Schnellspannelementen. Der in den Leimtank gegebene und über die Leimheizung verflüssigte und somit verarbeitbare Heißleim wird über die Leimpumpe aus dem Leimtank gepumpt und der Leimwalze an deren Mantelfläche zugeführt. Ein Leimschaber mit einer Schabeleiste ist der Leimwalze so nahe zugestellt, dass die Schabeleiste bei der Rotation der Leimwalze den überflüssigen Leim abzieht und nur ein dünner Leimfilm auf der Mantelfläche der Leimwalze verbleibt. Der an der Leimleiste verbleibende Leim wird dem Leimtank erneut zugeführt, womit ein Leimkreislauf entsteht. Die Einzelelemente sind jedoch fest miteinander verbunden, was bei der Vornahme der Reinigung des Leimwerkes, insbesondere der Beleimungswalze von Nachteil ist. Solche Leimwerke, müssen mit hohem Aufwand gereinigt werden. Die Reinigung ist aber gerade bei einer Heißleimanwendung von großer Bedeutung.To be able to provide a label piece with a glue strip, a gluing unit is used. The gluing unit consists of a glue tank, a glue heating, a glue bar, an glue pump and quick clamping elements. The hot glue added to the glue tank and liquefied via the glue heating and thus processable is pumped out of the glue tank via the glue pump and fed to the glue roller on its lateral surface. A glue scraper with a strip of glue is delivered to the glue roller so close that the strip of strips removes the superfluous glue during the rotation of the glue roller and only a thin glue film remains on the surface of the glue roller. The glue remaining on the glue bar is fed back to the glue tank, creating a glue circulation. However, the individual elements are firmly connected to each other, which is disadvantageous when carrying out the cleaning of the gluing unit, in particular the gluing roller. Such Glue works, must be cleaned with great effort. However, cleaning is of great importance in a hot glue application.

Prozessbedingt kommt es immer wieder zu sogenanntem Leimeinbrand und einer Verschmutzung der Beleimungswalze. Bei Reinigungszyklen muss die Beleimungswalze manuell vom Bediener gereinigt werden. Die Beleimungswalze wird dabei mit einem Reinigungsmittel eingesprüht und anschließend mit einer Stahlbürste manuell gereinigt. Der entstehende Schmutz kann in den fest verbundenen Leimtank wandern und den darin befindlichen Leim verschmutzen. Es ist die Aufgabe der vorliegenden Erfindung, eine vereinfachte Reinigung zu ermöglichen und dabei eine Verschmutzung des Leimtanks verhindern.Due to the process, so-called glue burn-in and contamination of the gluing roller occur time and again. During cleaning cycles, the gluing roller must be manually cleaned by the operator. The gluing roller is sprayed with a cleaning agent and then cleaned manually with a steel brush. The resulting dirt can migrate into the firmly bonded glue tank and contaminate the glue inside. It is the object of the present invention to enable a simplified cleaning and thereby prevent contamination of the glue tank.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Leimtank eine Koppelstelle aufweist, an der ein Leimschaber wieder entfernbar anbringbar ist. Die Anmelderin hat im Rahmen eines Projektes den Leimtank konstruktiv vom Leimwerk getrennt. Dadurch ist ein Abkoppeln bei Reinigungszyklen leicht möglich. Statt des Leimtanks oder eines Leimschabers kann ein speziell dafür vorgesehener Reinigungsbehälter angeschlossen werden, der die Schmutzreste auffängt. Eine auch als Schnittstelle bezeichnete Koppelstelle wurde entsprechend ausgebildet, so dass ein wechselbares Leimschabersystem geschaffen ist. An dieser Koppelstelle kann zum Durchführen der Reinigungsarbeiten statt eines Leimschabers eine Reinigungseinheit eingesetzt, vorzugsweise eingeklippst werden.This object is achieved in that the glue tank has a coupling point to which a glue scraper is removably attachable again. The applicant has structurally separated the glue tank from the gluing plant. This makes it easy to uncouple during cleaning cycles. Instead of the glue tank or a glue scraper, a specially designed cleaning container can be connected, which catches the dirt residue. A coupling point, also referred to as an interface, has been designed accordingly, so that a replaceable glue scraper system is created. At this coupling point can be used to perform the cleaning work instead of a glue scraper, a cleaning unit, preferably clipped.

Durch eine entsprechende Ausgestaltung kann vor dem Reinigen der Beleimungswalze der Leimtank mit seinem Anschluss von der Koppelstelle entfernt werden, der Leimschaber entfernt werden und stattdessen eine Reinigungseinheit eingesetzt werden. Diese Reinigungseinheit ermöglicht dann ein vom Leimtank getrenntes Reinigen des Leimwerkes. Die Reinigung kann somit automatisch erfolgen. Auch ist die Qualität der Reinigung höher als bei einer manuellen Reinigung und in dieser Güte auch reproduzierbar.By means of a corresponding embodiment, before the cleaning of the gluing roller, the glue tank with its connection can be removed from the coupling point, the glue scraper can be removed and instead a cleaning unit can be used. This cleaning unit then allows a separate from the glue tank cleaning the gluing unit. The cleaning can be done automatically. Also, the quality of the cleaning is higher than with a manual cleaning and in this quality also reproducible.

Vorteilhafte Ausführungsformen sind in den Unteransprüchen beansprucht und werden nachfolgend näher erläutert.Advantageous embodiments are claimed in the subclaims and are explained in more detail below.

So lässt sich die Reinigung verbessern, wenn die Koppelstelle bei abgenommenem Leimschaber zur Aufnahme einer Reinigungseinheit ausgebildet ist.Thus, the cleaning can be improved if the coupling point is formed with removed glue scraper for receiving a cleaning unit.

Wenn benachbart zu der Koppelstelle ein Anschluss eines Leimtanks wieder entfernbar mit dem Leimwerk verbindbar ist, so kann eine gleichförmige Leimschicht auf der Beleimungswalze eingestellt werden und eventuelle Unrundheiten oder Höhenunterschiede auf der Oberfläche der Beleimungswalze ausgeglichen werden.If, adjacent to the coupling point, a connection of a glue tank is removably connectable to the gluing unit, a uniform glue layer on the gluing roller can be adjusted and any irregularities or height differences on the surface of the gluing roller can be compensated.

Es ist von Vorteil, wenn zwischen dem Leimtank und dem Anschluss eine zum Leimleiten ausgebildete Leitung, wie ein Schlauch, vorhanden ist. Auf diese Weise kann der Leimtank auch in einer gewissen Entfernung von dem Leimwerk positioniert werden, was die Packaging-Maße des Leimwerkes und einer diese einsetzende Etikettiermaschine verbessert wird. Aufgrund eines Schlauches ist eine gewisse Flexibilität auch realisierbar, so dass der An- und Abkoppelvorgang des Leimtankes montagefreundlich ist.It is advantageous if between the glue tank and the terminal for a trained Leimleiten line, such as a hose is present. In this way, the glue tank can also be positioned at a certain distance from the gluing unit, which improves the packaging dimensions of the gluing unit and of a labeling machine employing it. Due to a hose a certain flexibility is also feasible, so that the coupling and uncoupling of the glue tank is easy to install.

Die Beleimungsqualität lässt sich steigern, wenn der Leimschaber eine an die Mantelfläche der Beleimungswalze heranfahrbare Schabeleiste aufweist.The quality of gluing can be increased if the glue scraper has a scraping strip approachable to the outer surface of the gluing roller.

Wenn die Reinigungseinheit eine Anschlussöffnung zum Zuführen eines Reinigungsmediums aufweist, so kann ein gesteuertes oder geregeltes Zuführen des Reinigungsmediums erreicht werden. Die Reinigungsleistung lässt sich dadurch nahezu beliebig einstellen.If the cleaning unit has a connection opening for supplying a cleaning medium, controlled or regulated feeding of the cleaning medium can be achieved. The cleaning performance can thus be set almost arbitrarily.

Wenn die Reinigungseinheit durch Leitung eines Reinigungsmediums, wie Druckluft und/oder eines Lösungsmittels, ausgelegt ist, so kann ein verschmutztes Reinigungsmittel einfach abgeleitet und entsorgt werden. Dies ist insbesondere zur Erfüllung von Umweltstandards von großem Vorteil.If the cleaning unit is designed by conducting a cleaning medium, such as compressed air and / or a solvent, a soiled cleaning agent can be easily removed and disposed of. This is particularly advantageous for meeting environmental standards.

Um eine Druckbeaufschlagung der Oberfläche der Beleimungswalze mit dem Reinigungsmittel zu ermöglichen, ist es von Vorteil, wenn die Reinigungseinheit zumindest eine der Beleimungswalze zugewandte Düse, vorzugsweise mehrere Düsen, was einen gleichbleibenden Reinigungserfolg nach sich zieht, aufweist.In order to allow pressurization of the surface of the gluing roller with the cleaning agent, it is advantageous if the cleaning unit has at least one nozzle facing the gluing roller, preferably several nozzles, which results in a consistent cleaning success.

Die Reinigungswirkung lässt sich noch erhöhen, wenn die Reinigungseinheit auf zumindest einer Außenseite zumindest einer Reinigungsbürste, vorzugsweise mehrere Reinigungsbürsten, die weiter vorzugsweise direkt neben den Düsen angeordnet sind, aufweist.The cleaning effect can be further increased if the cleaning unit has at least one outer side of at least one cleaning brush, preferably a plurality of cleaning brushes, which are furthermore preferably arranged directly next to the nozzles.

Besonders gute Wirkung haben Reinigungsbürsten aus Stahl, die auch besonders kostengünstig fertigbar und verbaubar sind. Alternativ können auch Reinigungsbürsten aus Messing, Kunststoff oder VA-Material verwendet werden.Cleaning brushes made of steel, which are also particularly inexpensive manufacturable and installable, have a particularly good effect. Alternatively, cleaning brushes made of brass, plastic or VA material can be used.

Die Aufgabe wird auch durch eine Etikettiermaschine mit einem Leimwerk gemäß der Erfindung gelöst.The object is also achieved by a labeling machine with a gluing unit according to the invention.

Die Figuren sind schematischer Natur und zeigen in perspektivischer Darstellung ein erstes Ausführungsbeispiel. Die Figuren sind lediglich zum Verständnis der Erfindung vorgesehen. In den Figuren sind die gleichen Elemente mit denselben Bezugszeichen versehen.The figures are schematic in nature and show a perspective view of a first embodiment. The figures are merely intended for understanding the invention. In the figures, the same elements are provided with the same reference numerals.

In Fig. 1 ist ein Leimwerk 1 dargestellt. Das Leimwerk 1 ist Teil einer Etikettiermaschine, die in Gänze nicht dargestellt ist. Das Leimwerk 1 ist mit einem Leimtank 2 verbunden. Der Leimtank 2 ist von dem Leimwerk 1 abkoppelbar. Er ist somit wieder entfernbar mit dem Leimwerk 1 verbindbar. Das Leimwerk 1 weist eine Koppelstelle 3 auf, an der ein auf diese Koppelstelle 3 angepasster Anschluss 4 wieder anbringbar ist. In dem vorliegenden Ausführungsbeispiel wird der Leimtank 2 über eine Leitung 5, die als Schlauch 6 ausgebildet ist, mit der Koppelstelle 3 verbunden, wobei ein Leimschaber 7 die Fluidleitung des Leimes zu der Oberfläche einer Beleimungswalze 8, die im Inneren des Leimwerkes 1 rotierbar angeordnet ist, sicherstellt.In Fig. 1 is a gluing unit 1 shown. The gluing unit 1 is part of a labeling machine, which is not shown in its entirety. Glue plant 1 is connected to a glue tank 2. The glue tank 2 can be decoupled from the gluing unit 1. He is thus removable again connected to the Glue 1. The gluing unit 1 has a coupling point 3 to which a connection 4 adapted to this coupling point 3 can be attached again. In the present embodiment, the glue tank 2 is connected via a line 5, which is designed as a hose 6, with the coupling point 3, wherein a glue scraper 7, the fluid line of the glue to the Surface of a Beleimungswalze 8, which is arranged rotatably inside the gluing unit 1, ensures.

Die Beleimungswalze 8 ist in Fig. 3 erkennbar, da in den anderen Figuren entweder der Leimschaber 7 oder eine Reinigungseinheit 9 die Sicht auf die Beleimungswalze 8 verdeckt. Die singuläre Reinigungseinheit 9 ist in Fig. 4 zu erkennen, genauso wie in den Figuren 5 und 6.The gluing roller 8 is in Fig. 3 recognizable, since in the other figures, either the glue scraper 7 or a cleaning unit 9 obscured the view of the gluing roller 8. The singular cleaning unit 9 is in Fig. 4 to recognize, as well as in the FIGS. 5 and 6 ,

Der Leimschaber 7 weist eine Schabeleiste auf, die heranfahrbar und mit einem geringen Spalt zur Oberfläche der Beleimungswalze 8 einstellbar angeordnet ist.The glue scraper 7 has a Schabeleiste, which is arranged to be approachable and adjustable with a small gap to the surface of the gluing roller 8.

Der Schlauch 6 kann ein weiteres Ende 10 aufweisen, das eine entsprechende Ausformung aufweist, um am Leimtank 2 angekoppelt zu werden. Auch dieses Ende 10 ist vom Leimtank 2 entfernbar, genauso wie durch das Entfernen des Leimschabers 7 im Bereich der Koppelstelle 3 die Verbindung zwischen dem Inneren des Leimwerkes 1, in dem die Beleimungswalze 8 angeordnet ist, und dem Leimtank 2 unterbrochen ist.The tube 6 may have another end 10 which has a corresponding shape to be coupled to the glue tank 2. Also, this end 10 is removable from the glue tank 2, just as by removing the glue scraper 7 in the region of the coupling point 3, the connection between the interior of the gluing unit 1, in which the gluing roller 8 is arranged, and the glue tank 2 is interrupted.

Die vom Leimtank 2 getrennte Konfiguration des Leimwerkes 1 mit noch eingesetztem Leimschaber 7 ist in Fig. 2 dargestellt. In Fig. 3 ist nicht nur die Koppelung vom Leimtank 2 gelöst, sondern auch der Leimschaber 7 aus dem Leimwerk 1 entfernt.The separate from the glue tank 2 configuration of Glue 1 with still inserted glue scraper 7 is in Fig. 2 shown. In Fig. 3 not only is the coupling of the glue tank 2 solved, but also the glue scraper 7 removed from the gluing unit 1.

In Fig. 4 ist in einem nachfolgenden Schritt der Montage die Beleimungswalze 8 durch die an der Koppelstelle 3 des Leimwerkes 1 eingesetzte Reinigungseinheit 9 verdeckt.In Fig. 4 In a subsequent step of the assembly, the gluing roller 8 is covered by the cleaning unit 9 inserted at the coupling point 3 of the gluing unit 1.

Die Reinigungseinheit 9 ist grundsätzlich kastenförmig ausgebildet und weist einen zusätzlichen Griff 11 auf, der die Handhabbarkeit der Reinigungseinheit 9 erleichtert.The cleaning unit 9 is basically box-shaped and has an additional handle 11, which facilitates the handling of the cleaning unit 9.

An einem unteren Abschnitt der Reinigungseinheit 9 ist eine Anschlussöffnung 12 zur Zufuhr eines Reinigungsmediums ausgebildet. Der Anschluss 12 kann als Gegenteil eines Klips-Elementes ausgebildet sein. Wird beispielsweise ein Schlauch auf die Anschlussöffnung 12 aufgeklippst, so kann Druckluft, ein Reinigungsmittel oder Mischungen davon unter Druck in das Innere der Reinigungseinheit 9 verbracht werden.At a lower portion of the cleaning unit 9, a connection opening 12 for supplying a cleaning medium is formed. The terminal 12 may be formed as the opposite of a clip element. If, for example, a hose is clipped onto the connection opening 12, compressed air, a cleaning agent or mixtures thereof can be brought under pressure into the interior of the cleaning unit 9.

Wie in der gedrehten Darstellung von Fig. 6 gut zu erkennen ist, sind auf der der Beleimungswalze 8 zugewandten Seite 13 in Reihe und Äquidistant zueinander angeordnete Düsen 14 angeordnet. Benachbart zu diesen Düsen sind eine Vielzahl von Reinigungsbürsten 15 angeordnet. In dem dargestellten Ausführungsbeispiel sind nicht alle Reinigungsbürsten 15 dargestellt, um die Positionierung der Düsen 14 visuell zu erleichtern. Allerdings ist auch genau so eine Ausgestaltung wie in Fig. 6 denkbar. Von Vorteil ist es jedoch, wenn die Fläche 13 zur Gänze mit Reinigungsbürsten 15 bedeckt ist, wobei in den Zwischenräumen zwischen den Reinigungsbürsten 15 die Düsen 14 angeordnet sind. Auch mehrere Reihen an Düsen 14 sind dabei denkbar.As in the rotated presentation of Fig. 6 can be clearly seen, are arranged on the Beleimungswalze 8 facing side 13 in series and equidistantly arranged nozzles 14. Adjacent to these nozzles, a plurality of cleaning brushes 15 are arranged. In the illustrated embodiment, not all of the cleaning brushes 15 are shown to visually facilitate the positioning of the nozzles 14. However, this is just as a design as in Fig. 6 conceivable. It is advantageous, however, if the surface 13 is completely covered with cleaning brushes 15, wherein in the spaces between the cleaning brush 15, the nozzles 14 are arranged. Several rows of nozzles 14 are conceivable.

Die Reinigungsbürsten 15 gelangen mit der Beleimungswalze 8 in Kontakt, während das Reinigungsmedium durch die Düsen 14 in Richtung der Beleimungswalze 8 ausgestoßen wird. Dabei werden auch die Reinigungsbürsten 15, die vorzugsweise aus Stahl gefertigt sind, wieder gereinigt.The cleaning brushes 15 come into contact with the gluing roller 8 while the cleaning medium is ejected through the nozzles 14 in the direction of the gluing roller 8. In this case, the cleaning brushes 15, which are preferably made of steel, cleaned again.

Die Beleimungswalze 8 wird dann mit chemischen Reinigungsmitteln eingesprüht und die Verschmutzung zusätzlich mechanisch durch die Reinigungsbürsten 15 gelöst. Dieser Reinigungszyklus ist nach einer vorgegebenen Betriebsstundenzahl durchzuführen. Dadurch wird die Produktionsleistung gesteigert.The Beleimungswalze 8 is then sprayed with chemical cleaning agents and the pollution additionally solved mechanically by the cleaning brush 15. This cleaning cycle must be carried out after a specified number of operating hours. This increases production output.
