Description

Die Erfindung betrifft eine Leimauftragsvorrichtung zum Auftragen von Leim auf Bestandteile von Schlauch- oder Bahnstücken nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a glue application device for applying glue to components of hose or track pieces according to the preamble of patent claim 1.

Bei der Herstellung beispielsweise von Beuteln oder Säcken, die vorzugsweise aus Papier bestehen, ist es notwendig, Leim auf Teile der für die Herstellung von Beuteln oder Säcken notwendigen Vor- oder Zwischenprodukte aufzutragen. Hierbei handelt es sich in der Regel um Bahnstücke oder, wenn diese bereits zu einem Schlauch zusammengelegt worden sind, auch Schlauchstücke. Soll etwa eine Papiertüte oder ein Papierbeutel mit einem Boden, der durch einfaches Umlegen eines Endes des Schlauchabschnitts auf eine Außenseite gebildet wird, hergestellt werden, so wird in der Regel Schlauchstück im Bereich des umzulegenden Endes einseitig mit Leim beaufschlagt. Solche Schlauchabschnitte werden häufig parallel zu ihrer Schlauchachse durch eine Vorrichtung zum Herstellen dieser Beutel transportiert. Die Falzkante, um die ein Ende des Schlauchabschnitts umgelegt wird, verläuft dann quer zur Transportrichtung der Schlauchabschnitte. Oft wird der Schlauchabschnitt dazu mit dem umzulegenden Ende voraus transportiert. Insbesondere zum Versehen von Bestandteilen der Schlauch- oder Bahnstücke mit Leim werden diese Stücke mit Mitteln zum Halten, beispielsweise Klemmstücken oder Zangen, auf einer Transportvorrichtung gehalten. In der Regel ist diese Transportvorrichtung ein trommelartiger Rotationskörper, der mit Nuten parallel zur Rotationsachse versehen ist, in welche Falzmesser das Bahn- oder Schlauchstück zur Falzung hineindrücken können. Die den Nuten benachbarten Bereiche der Transportvorrichtung dienen als Gegenlage bei dem Leimauftrag.For example, in the manufacture of bags or sacks, preferably made of paper, it is necessary to apply glue to parts of the precursor or intermediate products necessary for the manufacture of bags or sacks. These are usually pieces of track or, if these have already been folded into a tube, also pieces of hose. If, for example, a paper bag or a paper bag with a bottom, which is formed by simply turning one end of the hose section to an outer side, are produced, then, as a rule, piece of hose is loaded on one side with glue in the region of the end to be folded. Such tube sections are often transported parallel to their tube axis by a device for making these bags. The folded edge around which one end of the tube section is folded, then runs transversely to the transport direction of the tube sections. Often the tube section is transported to the front end to be umzulegenden. In particular, for providing components of the hose or track pieces with glue, these pieces are held by means for holding, for example clamping pieces or pliers, on a transport device. In general, this transport device is a drum-like body of revolution, which is provided with grooves parallel to the axis of rotation, in which folding blade can push the web or hose piece for folding. The grooves Adjacent areas of the transport device serve as an abutment in the glue application.

Der Leim wird in der Regel innerhalb der Leimauftragsvorrichtung in einem Leimreservoir, beispielsweise einem Leimbehälter, zur Verfügung gestellt und durch Leimtransportmittel auf die zu beleimenden Bestandteile der Schlauch- oder Bahnstücke transportiert. Die Leimtransportmittel definieren so einen Leimtransportweg. Das Leimreservoir kann eine untere, längliche Öffnung aufweisen. Unterhalb dieser Öffnung ist zumindest ein Mittel zur Leimentnahme angeordnet, welches in das Leimreservoir hineingreift und so Leim entnimmt und an weitere Leimübertragungsmittel weiterleitet. In der Regel ist dieses Mittel zur Leimentnahme als Walze ausgebildet. Es kann aber auch als umlaufendes Band ausgebildet sein, welches um Walzen geführt wird. Der Leim belegt die Walzen- oder die Bandoberfläche im wesentlichen in deren gesamter Breite.The glue is usually provided within the glue application device in a glue reservoir, for example a glue container, and transported by glue transport means onto the components of the hose or web pieces to be glued. The glue transporting agents thus define a glue transport path. The glue reservoir may have a lower elongate opening. Below this opening at least one means for Leimentnahme is arranged, which engages in the glue reservoir and thus removes glue and passes on to further glue transfer agent. As a rule, this means of sedimentation is designed as a roller. But it can also be designed as a circulating belt, which is guided around rollers. The glue occupies the roll or strip surface substantially in their entire width.

Der mit dem Mittel zur Leimentnahme transportierte Leim wird zumindest teilweise von einer Übertragungsvorrichtung abgenommen. Dazu weist die Übertragungsvorrichtung häufig für den Leimtransport vorgesehene Bestandteile und/oder Außenoberflächen auf. Diese Bestandteile können erhaben sein. Nachdem die Übertragungsvorrichtung in Wirkverbindung mit dem Mittel zur Leimentnahme gestanden hat, sind die Bestandteile und/oder Außenoberflächen der Übertragungsvorrichtung meist vollständig mit Leim beaufschlagt. Durch eine Berührung wird anschließend Leim in Form einer Leimspur auf die Schlauch- oder Bahnstücke übertragen. Ein erhabener Bestandteil kann beispielsweise als Formatteil ausgeprägt sein, das auf das Format der mit Leim zu versehenden Bestandteile von Schlauch- oder Bahnstücken abgestimmt ist, d. h. sowohl in Richtung der Schlauchachse als auch quer zur Schlauchachse die Ausdehnung der zu beleimenden Bestandteile hat. Bei der eingangs beschriebenen Herstellung von Beuteln mit einem umgelegten Ende ist dieses Formatteil oft ein mit einer rechteckigen Oberfläche versehenes, stempelartiges Element, das um eine Achse rotiert. Bei Formatwechseln der Schlauch- oder Bahnstücke ist zumindest die Breite des stempelartigen Elementes an die neue Breite der Beutel anzupassen.The glue transported by the means for sedimentation is at least partially removed by a transfer device. For this purpose, the transmission device often provided for the glue transport components and / or outer surfaces. These ingredients can be sublime. After the transfer device has been in operative connection with the means for sedimentation, the components and / or outer surfaces of the transfer device are usually fully loaded with glue. By a touch glue is then transferred in the form of a glue trace on the hose or track pieces. A raised component may for example be pronounced as a format part, which is tailored to the format of the glue to be provided components of hose or track pieces, ie both in the direction of the tube axis and transverse to the tube axis, the expansion of the components to be glued. In the above-described production of bags with a folded end of this format part is often provided with a rectangular surface, stamp-like element which rotates about an axis. When changing the format of the hose or web pieces, at least the width of the stamp-like element is adapted to the new width of the bag.

Formatteile können aber auch auswechselbar auf einer Walze aufgebracht sein. Bei einem Formatwechsel der Schlauch- oder Bahnstücke können die Formatteile abgezogen und durch solche anderen Formats ersetzt werden.Format parts can also be applied interchangeably on a roller. In a format change of the hose or track pieces, the format parts can be deducted and replaced by such other format.

Bei den beschriebenen Leimauftragsvorrichtungen des Standes der Technik müssen also bei einem Formatwechsel der Schlauch- oder Bahnstücke die Übertragungsvorrichtung oder zumindest Bestandteile davon ausgetauscht oder verändert werden. Insbesondere bei der Herstellung von Beuteln mit umgelegten Enden muss das stempelartige Element, mit dessen Breite auch die Breite der Leimspur auf den Schlauch- oder Bahnstücken festgelegt ist, zumindest bei jeder Veränderung der Schlauch- oder Bahnstückbreite ausgetauscht werden. Die Ausdehnung des stempelartigen Elementes in Richtung der Schlauch- oder Bahnachse kann dagegen oft erhalten bleiben. Dies führt zu unnötigen Stillständen der gesamten Vorrichtung und ist zudem, da die Übertragungsmittel' innerhalb der Vorrichtung nur schwer zu erreichen sind, sehr aufwändig. Beides führt daher zu hohen Umrüstkosten bei einem Formatwechsel der Schlauch- oder Bahnstücke beziehungsweise der daraus hergestellten Beutel.In the described glue application devices of the prior art, therefore, the transfer device or at least components thereof must be exchanged or changed during a format change of the hose or web pieces. In particular, in the production of bags with folded ends, the stamp-like element, with the width of the width of the glue line is set on the hose or track pieces must be replaced at least with each change in the hose or web piece width. The expansion of the stamp-like element in the direction of the hose or web axis, however, can often be maintained. This leads to unnecessary stoppages of the entire device and is also, since the transfer means' within the device are difficult to achieve, very expensive. Both therefore leads to high Umrüstkosten in a format change of the hose or web pieces or the bag made therefrom.

Die Patentschrift GB 896,291 beschreibt eine Klebstoffauftragsvorrichtung, bei der die Ausdehnung der Leimspur quer zur Transportrichtung der Beutel veränderbar ist. Dazu wirkt mit dem Leimentnahmemittel eine Walze zusammen, die dreieckförmige Ausnehmungen aufweist. Der von dem Leimentnahmemittel mitgenommene Leim kann zum Teil die Ausnehmung passieren, ein weiterer Teil des Leims wird durch die Walze von dem Leimentnahmemittel entfernt. Durch die Drehung der Walze kommen verschiedene Querschnitte des Dreiecks mit dem Leimentnahmemittel in Kontakt, so dass die Breite der Leimspur einstellbar ist.The patent GB 896,291 describes an adhesive application device in which the extension of the glue line is changeable transversely to the transport direction of the bag. For this purpose cooperates with the Leimentnahmemittel a roller having triangular recesses. The glue entrained by the sediment can partially pass through the recess, and another part of the glue is removed by the roller from the sediment. As a result of the rotation of the roller, different cross-sections of the triangle come into contact with the sampler so that the width of the glue track is adjustable.

Allerdings ist bei dieser Anordnung von Nachteil, dass das Profil der Leimspur nach außen abgeflacht ist, so dass ein gleichmäßiger Leimauftrag über die Breite des Beutels nicht mehr gewährleistet ist. Außerdem verändert sich mit der Verdrehung der Walze auch die Höhe der Leimspur. Diese Ist also nicht mehr getrennt einstellbar.However, in this arrangement, a disadvantage that the profile of the glue line is flattened outwards, so that a uniform glue application across the width of the bag is no longer guaranteed. In addition, with the rotation of the roller and the height of the glue line changed. This is therefore no longer separately adjustable.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zum Auftragen von Leim auf Bestandteile von Schlauch- oder Bahnstücken vorzuschlagen, bei der ein gleichmäßiger Leimauftrag über die Breite der zu beleimenden Beutel möglich ist.The object of the present invention is therefore to propose a device for applying glue to components of hose or track pieces, in which a uniform application of glue across the width of the bag to be glued is possible.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Demnach ist die Ausdehnung der Leimspur bereits auf der Übenragungsvorrichtung quer zur Transportrichtung der Schlauch- oder Bahnstücke veränderbar. Hierbei und im Folgenden ist mit den Begriffen "Ausdehnung" und "Breite" die Ausdehnung quer zur Transportrichtung der Schlauch- oder Bahnstücke gemeint.According to the invention, this object is solved by the features of the characterizing part of claim 1. Accordingly, the extent of the glue trace is already changeable on the surveying device transversely to the transport direction of the tube or web pieces. Here and below is meant by the terms "expansion" and "width" the extension transverse to the transport direction of the hose or track pieces.

Durch diese Maßnahme belegt der Leim nur eine vorbestimmte Fläche auf der zumindest einen Obertragungsvorrichtung oder auf den für den Leimtransport vorgesehenen Bestandteilen und/oder Außenoberflächen. Die Ausdehnung der Leimspur wird also noch vor der Berührung von Übertragungsvorrichtung und Schlauch- oder Bahnstücken an die Breite der mit Leim zu versehenden Flächen der Schlauch- oder Bahnstücke angepasst. Damit kann eine Leimspur der vorgesehenen Breite auf die Schlauch- oder Bahnstücke übertragen werden, ohne dass bei einer Änderung der Breite der Schlauch- oder Bahnstücke eine Änderung der Gestalt der Übertragungsvorrichtung vorgenommen werden muss. Weist die Übertragungsvorrichtung beispielsweise zum Leimtransport erhabene Bestandteile auf so können diese auch bei einem Formatwechsel der Schlauch- oder Bahnstücke beziehungsweise der zu produzierenden Beutel an der Übertragungsvorrichtung verbleiben. Die Breite von für den Leimtransport vorgesehenen Bestandteilen der Übertragungsvorrichtung, also beispielsweise von erhabenen Teile wie etwa Formatteile oder stempelartige Elemente, braucht nun nicht mehr an die Breite der mit Leim zu versehenden Flächen der Schlauch- oder Bahnstücke angepasst zu werden. Die für den Leimtransport vorgesehenen Bestandteile können Breiten aufweisen, die größer sind als die Breite der für den betreffenden Produktionsauftrag verarbeiteten Schlauch- oder Bahnstücke. Es ist daher ausreichend, diese Bestandteile mit einer Breite vorzusehen, die der maximalen Breite der in der Vorrichtung verarbeitbaren Schlauch- oder Bahnstücke entspricht. Eine Lagerhaltung für solche Bestandteile der Übertragungsvorrichtung, also für erhabene Bestandteile wie etwa stempelartige Elemente oder Formatteile, kann unterbleiben, was sich neben verkürzten Stillstandszeiten der Vorrichtung beim Formatwechsel kostendämpfend auswirkt.By this measure, the glue occupies only a predetermined area on the at least one transfer device or on the glue transport provided components and / or outer surfaces. The extent of the glue trace is thus adapted to the width of the surfaces to be provided with glue hose or track pieces before contact of the transfer device and hose or track pieces. In order for a glue trace of the intended width can be transferred to the hose or track pieces without a change in the shape of the transfer device must be made when changing the width of the hose or web pieces. If, for example, the transfer device has raised components for glue transport, then they can remain on the transfer device even if the format of the tube or web pieces or the bags to be produced changes. The width of intended for the glue transport components of the transfer device, so for example, of raised parts such as format parts or stamp-like elements, now no longer needs to be adapted to the width of the areas to be provided with glue hose or track pieces. The components provided for the glue transport may have widths which are greater than the width of the hose or web pieces processed for the relevant production order. It is therefore sufficient to provide these components with a width that corresponds to the maximum width of the hose or web pieces that can be processed in the device. A storage for such components of the transfer device, ie for raised components such as stamp-like elements or format parts, can be omitted, which in addition to reduced downtime of the device during format change cost-effective effect.

Mit der erfindungsgemäßen Leimauftragsvorrichtung können noch weitere Vorteile erzielt werden. So kann auch bereits die Breite der Leimspur in dem oder auf dem Mittel zur Leimentnahme verändert werden. Zu diesem Zweck kann auch vom Mittel der Leimentnahme Leim wieder abgenommen werden. Es ist jedoch auch möglich, die Leimspur nur in einer Ausdehnung auf die Mittel zur Leimentnahme aufzutragen, die im wesentlichen der späteren Ausdehnung der Leimspur auf den Schlauch- oder Bahnstücken entspricht. Dadurch wird der gesamte vom Mittel zur Leimentnahme weitergeleitete Leim durch das Übertragungsmittel abgenommen, so dass - anders als in einer Vorrichtung des Standes der Technik, kein überschüssiger Leim an dem Mittel zur Leimentnahme antrocknen kann. Besonders deutlich wird diese Tatsache, wenn das Mittel zur Leimentnahme als Walze ausgebildet ist. In Leimauftragsvorrichtungen des Standes der Technik waren die Enden der Walzen regelmäßig mit an- oder ausgetrocknetem Leim verschmutzt. Vor allem letzteres führte häufig zu hohem Wartungsaufwand, der bei einer erfindungsgemäßen Vorrichtung stark verringert ist.With the glue application device according to the invention still further advantages can be achieved. Thus, even the width of the glue trace in or on the means for Leimentnahme be changed. For this purpose glue can also be removed again from the means of glueing. However, it is also possible to apply the glue lane only in one extension to the means for Leimentnahme, which corresponds essentially to the subsequent expansion of the glue trace on the hose or track pieces. As a result, the entire passed on by the means for Leimentnahme glue by the Transfer means removed, so that - unlike in a device of the prior art, no excess glue on the means for Leimentnahme can dry. This fact becomes particularly clear when the agent for sedimentation is designed as a roller. In prior art size applicators, the ends of the rolls were regularly soiled with dried or dried glue. Especially the latter often led to high maintenance, which is greatly reduced in a device according to the invention.

In bevorzugter Ausgestaltung der Erfindung sind Leimflussbegrenzungsmittel vorgesehen, welche in den Leimtransportweg einführbar sind. Auf diese Weise ist der Leimfluss abschnittsweise begrenzbar. So können die Leimflussbegrenzungsmittel derart in den Leimtransportweg einführbar sein, dass durch die Positionierung der Leimflussbegrenzungsmittel die Ausdehnung der Leimspur quer zur Transportrichtung der Schlauch- und Bahnstücke definierbar ist. Durch die Einführung beziehungsweise Positionierung von Leimflussbegrenzungsmitteln kann also die Breite der Leimspur bei einem Formatwechsel der zu produzierenden Beutel mit besonders geringem Aufwand angepasst werden. Die Leimflussbegrenzungsmittel können dabei unterschiedliche Funktionen haben. Sie können den Leim, der über die Breite der Schlauchstücke hinausgeht, wieder von dem Mittel zur Leimentnahme oder von der Übertragungsvorrichtung entfernen. Dies kann durch Abkratzen oder Abschaben erfolgen. Auch können trichterförmig angeordnete Leimflussbegrenzungsmittel vorgesehen sein, die die mit einer Anfangsbreite auf dem Mittel zur Leimentnahme aufgetragene Leimspur in ihrer Ausdehnung quer zur Transportrichtung der Schlauch- oder Bahnstücke im Verlaufe des Leimtransports begrenzen. Mit anderen Leimflussbegrenzungsmitteln kann bereits die Anfangsbreite der Leimspur an die Breite der Schlauch- oder Bahnstücke angepasst werden.In a preferred embodiment of the invention, glue flow limiting means are provided, which can be inserted into the glue transport path. In this way, the glue flow can be limited in sections. Thus, the Leimflussbegrenzungsmittel can be inserted into the glue transport path such that the extension of the glue line is transverse to the transport direction of the hose and track pieces defined by the positioning of the Leimflussbegrenzungsmittel. By introducing or positioning Leimflussbegrenzungsmitteln so the width of the glue track can be adjusted in a format change of the bags to be produced with very little effort. The Leimflussbegrenzungsmittel can have different functions. You can remove the glue, which goes beyond the width of the pieces of hose, again from the means for Leimentnahme or from the transfer device. This can be done by scraping or scraping. Also funnel-shaped Leimflussbegrenzungsmittel can be provided which limit the applied with an initial width on the Leimentnahme Leimspur in their extension transverse to the transport direction of the hose or track pieces in the course of glue transport. With other Leimflussbegrenzungsmitteln already the initial width of the glue line can be adapted to the width of the hose or track pieces.

Hierbei ist es besonders bevorzugt, wenn das oder die Leimflussbegrenzungsmittel quer zur Transportrichtung der Schlauch- oder Bahnstücke, also entlang der Achse des rotierenden Leimtransportmittels, verschiebbar ist oder sind. Auf diese Weise kann bei einem Formatwechsel der zu produzierenden Beutel die Ausdehnung der Leimspur auf besonders einfache Weise angepasst werden.In this case, it is particularly preferred if the or the glue flow limiting means is or can be displaced transversely to the transport direction of the tube or web pieces, ie along the axis of the rotating glue transport means. In this way, in a format change of To be produced bags the expansion of the glue track can be adapted in a particularly simple manner.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung kann das zumindest eine Leimflussbegrenzungsmittel eine Seitenwand des Leimbehälters sein. Je nach Breite des zu beleimenden Bereichs des Schlauch- oder Bahnstückes kann die untere Auslassöffnung des Leimbehälters vergrößert oder verkleinert werden, so dass bereits am Anfang des Leimtransportweges die Ausdehnung der Leimspur beeinflusst werden kann. Zu diesem Zweck können auch lediglich die Abdichtelemente verschoben werden, die den Spalt zwischen dem Leimbehälter und dem Mittel zur Entnahme von Leim abdichten, so dass kein Leim durch diesen Spalt verloren geht.In a further advantageous embodiment of the invention, the at least one Leimflussbegrenzungsmittel be a side wall of the glue container. Depending on the width of the area of the hose or web piece to be glued, the lower outlet opening of the glue container can be enlarged or reduced so that the extent of the glue trace can already be influenced at the beginning of the glue transport path. For this purpose, only the sealing elements can be moved, which seal the gap between the glue container and the means for removing glue, so that no glue is lost through this gap.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist das zumindest eine Leimflussbegrenzungsmittel ein streifenförmiges Element. Mit diesem streifenförmigen Element kann Leim von dem zumindest einen Mittel zur Leimentnahme und/oder von der Übertragungsvorrichtung entfernt oder die Auftragung von Leim in der Breite begrenzt werden. Dieses streifenförmige Element kann dabei mit einer Kante oder Teilen davon an die Oberfläche des Mittels zur Leimentnahme angestellt werden. Das streifenförmige Element wirkt dabei wie ein Rakelmesser und kann Leim von der Oberfläche abnehmen und eine Leimspur der vorgesehenen Breite erzeugen. Dabei kann der abgenommene Leim auf geeignete Weise, etwa durch ein Auffang- und Weiterleitungssystem, wieder dem Leimreservoir zugeführt werden. Derartige streifenförmige Elemente lassen sich auf sehr einfache und damit bequeme Weise relativ zu den Mittel zur Leimentnahme verschieben. Dies kann manuell oder motorisch erfolgen. Ein verschiebbares streifenförmiges Element lässt sich dabei auch in Kombination mit einem Leimbehälter mit zumindest einer verschiebbaren Seitenwand oder in Kombination mit einem verschiebbaren Leimbehälter einsetzen.In a further preferred embodiment of the invention, the at least one glue flow-limiting means is a strip-shaped element. With this strip-shaped element, glue can be removed from the at least one means for holding and / or from the transfer device, or the application of glue in the width can be limited. This strip-shaped element can be employed with an edge or parts thereof to the surface of the means for Leimentnahme. The strip-shaped element acts like a doctor blade and can remove glue from the surface and produce a glue trace of the intended width. In this case, the removed glue can be supplied to the glue reservoir in a suitable manner, for example by a collecting and forwarding system. Such strip-shaped elements can be moved in a very simple and thus convenient way relative to the means for Leimentnahme. This can be done manually or by motor. A displaceable strip-shaped element can also be used in combination with a glue container with at least one displaceable sidewall or in combination with a displaceable glue container.

Vorteilhaft ist dabei, wenn das streifenförmige Element zumindest teilweise aus Metall besteht. Wenn die Oberfläche des Mittels zur Leimentnahme aus Gummi oder ähnlichem Material besteht, wird derartig ein effektives Zusammenwirken erreicht, so dass Leim durch das streifenförmige Element zuverlässig abgenommen wird.It is advantageous if the strip-shaped element is at least partially made of metal. If the surface of the composition is made of rubber or similar material, then such an effective interaction achieved so that glue is reliably removed by the strip-shaped element.

Oft sind besteht die Oberfläche des Mittels zur Leimentnahme aus einem Metall, beispielsweise Messing. Dann kann es vorteilhaft sein, wenn das streifenförmige Element zumindest teilweise aus Kunststoff besteht. ,Often, the surface of the sedimentation agent is a metal, such as brass. Then it may be advantageous if the strip-shaped element is at least partially made of plastic. .

Fig. 1 zeigt eine Prinzipskizze einer Vorrichtung 1 zum Aufbringen von Leim auf Bestandteile von Schlauch- oder Bahnstücken. Ein Schlauchstück 2 wird auf einer rotierenden Transporttrommel 3, die in einem nicht gezeigten Maschinengestell drehbar gelagert ist, mit Hilfe der nicht näher beschriebenen Haltevorrichtungen gehalten und in Transportrichtung z transportiert. Das Schlauchstück liegt auf einer Gegenlage 4 zum Falzmesser auf. Durch Zusammenwirken des nicht dargestellten Falzmessers mit der Gegenlage 4 wird das Schlauchstück mit einer Falzkante 8 versehen. Oberhalb der Transporttrommel ist eine Leimübertragungsvorrichtung 5 angeordnet, die um die Achse 6 drehbar im nicht gezeigten Maschinengestell gelagert ist. Im Betrieb dreht die Transporttrommel 3 in Richtung des Pfeils A, die Leimübertragungsvorrichtung 5 in Richtung des Pfeils B. An der Leimübertragungsvorrichtung 5 sind so genannte Leimsegmente 7 mit Abstand zur Achse 6 angebracht. Dieser Abstand kann konstant oder veränderbar sein. Insbesondere ist es denkbar, dass der Abstand, etwa durch eine Kurvenführung, sich im Laufe einer Umdrehung der Transporttrommel 3 verändert. Die Leimsegmente 7 übertragen Leim im Bereich der Falzkante 8 auf die Schlauchstücke 2, so dass nach einem späteren Umlegen des abgefalzten Endes 9 der beleimte Bereich vollständig abgedeckt ist. Im weiteren Verlauf der Rotation der Transporttrommel 3 wird durch ein nicht dargestelltes Bauteil, beispielsweise eine auf der Oberfläche der Transporttrommel 3 abrollende Rolle, das abgefalzte Ende 9 auf eine Außenoberfläche des Schlauchstücks 2 umgeklappt. Fig. 1 shows a schematic diagram of a device 1 for applying glue to components of hose or track pieces. A piece of tubing 2 is held on a rotating transport drum 3, which is rotatably mounted in a machine frame, not shown, with the aid of the holding devices not described in more detail and transported in the transport direction z. The piece of hose rests on an abutment 4 to the folding blade. By interaction of the folding blade, not shown, with the counter-layer 4, the piece of hose is provided with a folded edge 8. Above the transport drum, a glue transfer device 5 is arranged, which is mounted rotatably about the axis 6 in the machine frame, not shown. In operation, the transport drum 3 rotates in the direction of the arrow A, the glue transfer device 5 in the direction of the arrow B. At the glue transfer device 5 so-called glue segments 7 are mounted at a distance from the axis 6. This distance can be constant or changeable. In particular, it is conceivable that the distance, for example by a curve guide, changes in the course of a revolution of the transport drum 3. The glue segments 7 transfer glue in the region of the folded edge 8 onto the tube pieces 2, so that after a later folding of the folded end 9 the glued area is completely covered. In the further course of the Rotation of the transport drum 3 is folded over by an unillustrated component, for example, a rolling on the surface of the transport drum 3 role, the folded end 9 on an outer surface of the hose piece 2.

Die Falzkanten 8 werden, wie bereits beschrieben, durch ein nicht dargestelltes Falzmesser in das Schlauchstück eingebracht. Dieses Falzmesser ist beweglich an der Leimübertragungsvorrichtung 5 befestigt. Der Abstand des Falzmessers zur Achse 6 wird durch eine Kurvensteuerung variiert, so dass das Falzmesser beim Passieren der Leimwalze 10 leicht zur Achse 6 hingezogen wird, um die Leimwalze 10 nicht zu berühren. Weiterhin dient die Kurvensteuerung dem Hineindrücken des Schlauchstücks 2 in die Nut 11 der Gegenlage 4 zur Erzeugung der Falzkante.The folded edges 8 are, as already described, introduced by a not shown folding blade in the hose piece. This folding blade is movably attached to the glue transfer device 5. The distance of the folding blade to the axis 6 is varied by a cam control, so that the folding blade when passing the glue roller 10 is easily attracted to the axis 6, so as not to touch the glue roller 10. Furthermore, the cam control serves to push the hose piece 2 into the groove 11 of the counter-layer 4 to produce the folded edge.

Die Leimwalze 10, von der die Leimsegmente 7 den Leim abnehmen, ist drehbar in Seitenrahmen 12, von denen in der Fig. 1 einer sichtbar ist und welche mit dem Maschinenrahmen, beispielsweise über Traversen oder sonstige Verbindungselemente, verbunden sind, gelagert. Oberhalb der Leimwalze 10 ist ein Leimbehälter 13 angeordnet, der an seiner Unterseite eine längliche Öffnung aufweist, die jedoch vollständig durch die Leimwalze 10 abgedeckt ist. Auf diese Weise wird der durch die untere Öffnung des Leimbehälters 13 durchtretende Leim vollständig durch die Leimwalze 10 mitgenommen. Um das Austreten des Leims zwischen den Seitenwänden 14 des Leimbehälters 13 und der Leimwalze 10 zu vermeiden, sind dort Abdichtelemente 15 vorgesehen.The glue roller 10, from which the glue segments 7 remove the glue, is rotatable in side frames 12, of which in the Fig. 1 one is visible and which are connected to the machine frame, for example via trusses or other fasteners, stored. Above the glue roller 10, a glue container 13 is arranged, which has on its underside an elongated opening, which is completely covered by the glue roller 10. In this way, the glue passing through the lower opening of the glue container 13 is completely entrained by the glue roller 10. In order to avoid the leakage of the glue between the side walls 14 of the glue container 13 and the glue roller 10, sealing elements 15 are provided there.

Die Umfangsgeschwindigkeit der Leimwalze 10 ist so bemessen, dass sich die Oberfläche der Leimwalze 10 während einer vollständigen Rotation der Leimübertragungsvorrichtung 5 um die Breite des Leimsegmentes 7 oder um die Summe der Breiten der Leimsegmente fortbewegt hat. Die Umlaufgeschwindigkeit kann dabei variieren. Auf diese Weise wird sichergestellt, dass der an der Leimwalze anhaftende Leim vollständig abgenommen wird.The peripheral speed of the glue roller 10 is dimensioned so that the surface of the glue roller 10 has moved during a complete rotation of the glue transfer device 5 by the width of the glue segment 7 or by the sum of the widths of the glue segments. The rotational speed can vary. In this way it is ensured that the glue adhering to the glue roller is completely removed.

In dem Seitenrahmen 12 ist eine Ausnehmung 16 vorgesehen. In dieser Ausnehmung 16 ist eine Rolle 17 angeordnet, die durch die Schraube 18 gedreht werden kann. Auf dem oberen Scheitelpunkt der Rolle 17 liegt ein messerartiger Streifen 19 auf, der sich in axialer Richtung der Leimwalze 10 erstreckt. Durch die Drehung der Rolle 17 kann nun der Streifen 19 in axialer Richtung der Leimwalze bewegt werden. Der Streifen 19 liegt mit einer Seitenkante an der Leimwalze 10 an und nimmt Teile des von der Leimwalze 10 transportierten Leims von dieser ab. In diesem Zusammenhang ist zu betonen, dass durch Ergreifen des Streifens 19 dieser auch direkt manuell verschoben werden kann. Dies ist insbesondere dann möglich, wenn der Streifen von außerhalb der Seitenrahmen 12 erfassbar ist. In diesem Fall kann sogar auf die Schraube 18, die Rolle 17 und die Ausnehmung 16 verzichtet werden.In the side frame 12, a recess 16 is provided. In this recess 16, a roller 17 is arranged, which can be rotated by the screw 18. On the upper vertex of the roller 17 is a knife-like strip 19, which extends in the axial direction of the glue roller 10. By the rotation of the roller 17, the strip 19 can now be moved in the axial direction of the glue roller. The strip 19 rests against the glue roller 10 with a side edge and removes parts of the glue transported by the glue roller 10 therefrom. In this context, it should be emphasized that by grasping the strip 19, this can also be moved directly manually. This is possible in particular if the strip can be detected from outside the side frames 12. In this case, even the screw 18, the roller 17 and the recess 16 can be dispensed with.

Die Fig. 2 zeigt die Ansicht des Schnitts II-II in Fig. 1. In dieser Figur sind nochmals die Seitenrahmen 12, die Leimwalze 10, die Schrauben 18, die Rollen 17 und die Streifen 19 zu sehen. Auf nicht dargestellte Weise ist ein Halterahmen 20 mit dem Leimbehälter, dem Seitenrahmen 12 und/oder dem Maschinenrahmen verbunden. In diesem Halterahmen 20 ist ein Haltebalken 21 verschiebbar gelagert. Die Verschiebung in im wesentlichen radialer Richtung der Leimwalze 10 erfolgt durch eine Stellschraube 22, die in ein in den Halterahmen 20 eingebrachtes Innengewinde eingeschraubt und die drehbar, aber unverschieblich in dem Halterahmen 20 gelagert ist. Dieser Haltebalken 21 dient den Streifen 19 als Gegenlage, so dass sie auch bei Drehung der Leimwalze 10 ortsfest verbleiben. In diesen Haltebalken 21 sind Führungen eingearbeitet, die ein Verschieben der Streifen in axialer Richtung der Leimwalze 10 zulassen, aber eine Verschiebung in radialer Richtung zu vermeiden.The Fig. 2 shows the view of section II-II in Fig. 1 , In this figure, the side frames 12, the glue roller 10, the screws 18, the rollers 17 and the strips 19 can be seen again. In a manner not shown, a holding frame 20 is connected to the glue container, the side frame 12 and / or the machine frame. In this holding frame 20, a holding bar 21 is slidably mounted. The displacement in a substantially radial direction of the glue roller 10 is effected by a set screw 22, which is screwed into an inserted into the holding frame 20 internal thread and which is rotatably mounted but immovably in the holding frame 20. This holding bar 21 serves the strip 19 as an abutment, so that they remain stationary even when the glue roller 10 is rotated. In these support bar 21 guides are incorporated, which allow a displacement of the strips in the axial direction of the glue roller 10, but to avoid a shift in the radial direction.

Weiterhin ist ein nicht sichtbarer Abstreifbalken vorgesehen. Mit diesem Abstreifbalken ist die Höhe der Leimspur auf der Leimwalze 10 beeinflussbar. Für die Verschiebung dient eine zweite, in ein in den Halterahmen 10 eingebrachtes Innengewinde eingeschraubte Stellschraube 23. Mit dieser Stellschraube 23 erfolgt ein Feinjustage in bezug auf die Leimwalze 10.Furthermore, a non-visible scraper bar is provided. With this Abstreifbalken the height of the glue trace on the glue roller 10 can be influenced. For the displacement serves a second, screwed into an inserted into the holding frame 10 internal screw set screw 23. With this screw 23 is a fine adjustment with respect to the glue roller 10th

Der Balken 20 und der Abstreifbalken können auch als ein einziges Bauteil, welche also beide Funktionen in sich vereint, ausgestaltet sein.The beam 20 and the scraper bar can also be designed as a single component, which thus combines both functions in itself.

Insgesamt ist also durch Drehungen an den Schrauben 18, 22, 23 die Größe des Durchlasses 24 und damit die Dimension der Leimspur festlegbar, so dass nur eine vorbestimmte Menge Leim das Leimsegment erreicht. Insbesondere die Breite der von dem Leim belegten Fläche auf der Leimwalze 10 und damit auch auf dem Leimsegment 7 ist durch die gezeigte Vorrichtung in einfacher Weise einstellbar. Bezugszeichenliste 1 Vorrichtung zum Auftragen von Leim auf Bestandteile von Schlauch- oder Bahnstücken 2 Schlauchstück 3 Transporttrommel 4 Gegenlage zum Falzmesser 5 Leimübertragungsvorrichtung 6 Drehachse der Leimübertragungsvorrichtung 7 Leimsegment 8 Falzkante 9 abgefalztes Ende 10 Leimwalze 11 Nut 12 Seitenrahmen 13 Leimbehälter 14 Seitenwand des Leimbehälters 15 Abdichtelement 16 Ausnehmung 17 Rolle 18 Schraube 19 messerartiger Streifen 20 Halterahmen 21 Haltebalken 22 Stellschrauben 23 Stellschrauben 24 Leimdurchlass A Drehrichtung der Transporttrommel 3 B Drehrichtung der Leimübertragungsvorrichtung 5 z Transportrichtung der Schlauchstücke 2 Overall, therefore, by rotation of the screws 18, 22, 23, the size of the passage 24 and thus the dimension of the glue track can be fixed, so that only a predetermined amount of glue reaches the glue segment. In particular, the width of the area occupied by the glue on the glue roller 10 and thus also on the glue segment 7 can be adjusted in a simple manner by the device shown.
