Description

Die Erfindung betrifft einen Bodenmacherzylinder einer Beutelmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a Bodenmacherzylinder a bag machine after the preamble of claim 1.

Beutelmaschinen sind bekannt. Sie werden beispielsweise in Schriften DE 42 05 062 A1, DE 197 02 144 A1 und F 2 548 161 gezeigt. In der Regel ist das funktionale Kernstück einer solchen Maschine ein Bodenmacherzylinder. Dieser Bodenmacherzylinder übernimmt in der Regel Schlauchstücke, welche aus einem Papierschlauch, der von einer Abwickeleinheit abgewickelt worden ist, in einer Abrisseinheit zu Papierschlauchstücken oder -abschnitten vereinzelt worden ist. Der Bodenmacherzylinder übernimmt diese Papierschlauchstücke, arretiert diese an seinem Umfang und führt sie während einer Umdrehung verschiedenen Bearbeitungsstationen, die um den Bodenmacherzylinder angeordnet sind, zu. Hierbei werden an den Schlauchstücken Einschläge ausgebildet, welche verleimt und zusammen gefaltet werden und auf diese Weise feste Beutelböden bilden. In der Regel wird das Schlauchstück mit dem späteren Boden voraus transportiert.Pouch machines are known. They are used, for example, in DE 42 05 062 A1, DE 197 02 144 A1 and F 2 548 161. In general, that is functional core of such a machine is a bottoming cylinder. This Bottom cylinder usually takes pieces of hose, which made a paper tube which has been unwound from an unwinding unit, in a tear unit to paper tube pieces or sections isolated has been. The Bodenmacherzylinder takes over these paper tube pieces, locks it to its circumference and guides it during a turn various processing stations that are around the floor maker cylinder are arranged, too. Here are the hose pieces impacts formed, which are glued and folded together and on this Form solid bag bottoms. In general, the hose piece with the transported later soil ahead.

Zur Schließung des Bodens ist eine der Bodenklappen, welche zur Bildung des Bodens übereinander gelegt werden müssen, zu ergreifen und zu falten. Eine der Bodenklappen kann dadurch geschlossen werden, dass diese Bodenklappe auf einen fest montierten Widerstand läuft und dadurch umgeklappt wird. Die zweite Bodenklappe muss jedoch in Transportrichtung umgeklappt werden. Dazu muss diese Bodenklappe kurzzeitig schneller bewegt werden als das Schlauchstück. Zu diesem Zweck befinden sich am Umfang des Bodenmacherzylinders rotierende Teile, die in der Regel sichelförmig ausgebildet sind. Diese werden vorzugsweise über Ellipsenräder angetrieben, welche mechanisch mit dem Antrieb des Bodenmacherzylinders gekoppelt sind. Mithilfe der Ellipsenräder werden die rotierenden Teile kurzzeitig in einer so hohen Geschwindigkeit bewegt, dass sie sich schneller als das Schlauchstück bewegen und so die Bodenklappe zu schließen vermögen. Dabei ist es aber auch wichtig, die Phasenlage, die die rotierenden Teile relativ zum Bodenmacherzylinder einnehmen, in Abhängigkeit von dem Bodenformat und damit in Abhängigkeit von der Größe der Bodenklappe einzustellen. Bei einem Formatwechsel ist es daher erforderlich, die rotierenden Teile von dem Antrieb zu lösen, gemäß dem neuen Format neu zu justieren und wieder zu befestigen. Zusätzlich müssen die rotierenden Teile gegen solchen größeren oder kleineren Ausmaßes ausgetauscht werden, wenn Schlauchstücke kleinerer beziehungsweise größere Breite zur Herstellung von Beuteln verwendet werden.To close the floor is one of the bottom flaps, which is used to form the Soil must be placed on top of each other, to grab and fold. A The bottom flaps can be closed by using this bottom flap on a fixed resistor runs and is folded over. The second bottom flap, however, must be folded in the transport direction. This bottom flap must be moved faster than that for a short time Piece of hose. For this purpose, the scope of the Treadmill rotating parts, usually sickle-shaped are formed. These are preferably driven by elliptical wheels, which are mechanically coupled to the drive of the Bodenmacherzylinders. Using the elliptical wheels, the rotating parts are briefly in such a way high speed moves faster than the hose piece move and thus be able to close the bottom flap. But that's it Also important, the phase position, the rotating parts relative to Take Bodenmacherzylinder, depending on the soil format and to adjust depending on the size of the bottom flap. At a Format change therefore requires the rotating parts from the drive to be readjusted and readjusted according to the new format. In addition, the rotating parts against such larger or smaller Extent are replaced when pieces of hose smaller or larger width used for the production of bags become.

Diese Anpassungen der rotierbaren Teile bei einem Formatwechsel ist jedoch sehr umständlich und zeitraubend.However, these adjustments of the rotatable parts in a format change is very cumbersome and time consuming.

Aufgabe der vorliegenden Erfindung ist es daher, eine Beutelmaschine vorzuschlagen, bei der die Anpassung der rotierenden Teile an neue Beutelformate einfacher und schneller erfolgen kann.Object of the present invention is therefore a bag machine to propose adapting the rotating parts to new ones Bag formats can be done easier and faster.

Die Aufgabe wird durch die Merkmale der kennzeichnenden Teile der Ansprüche 1 und 4 gelöst.The task is characterized by the characteristics of the characterizing parts of the Claims 1 and 4 solved.

Demzufolge ist die Phasenlage des rotierbaren Teils zum Bodenmacherzylinder bei Betrieb der Beutelmaschine verstellbar. Auf diese Weise wird vermieden, zum Zwecke des Formatwechsels die Beutelmaschine still zu setzen. Weiterhin muss das rotierbare Teil bei einem Formatwechsel nicht mehr ausgetauscht werden. Ein Formatwechsel kann damit bedeutend schneller erfolgen.As a result, the phase position of the rotatable part is the grounding cylinder adjustable during operation of the bag machine. This will avoid to put the bag machine down for the purpose of format change. Farther the rotatable part no longer needs to be replaced when the format is changed become. A format change can thus be done much faster.

Besonders vorteilhaft ist es, wenn die Bewegung des Bodenmacherzylinders und des rotierbaren Teils mechanisch gekoppelt sind und wenn in der Beutelmaschine zumindest ein Differential vorgesehen ist, mit welchem die Verstellung der Phasenlage vorgenommen wird. In einem solchen Differential kann der Teil, welcher die rotierbaren Teile antreiben, gegenüber dem Antrieb des Bodenmacherzylinders verdreht werden. Dieses kann beispielsweise mechanisch, aber auch mittels eines Stellmotors erfolgen.It is particularly advantageous if the movement of the Bodenmacherzylinders and the rotatable part are mechanically coupled and when in the Bag machine at least one differential is provided with which the Adjustment of the phase position is made. In such a differential For example, the part which drives the rotatable parts can be opposite to the drive twisted the Bodenmacherzylinders. This can for example mechanically, but also by means of a servomotor.

In einer weiteren Ausführungsform der Erfindung sind für den Bodenmacherzylinder und das rotierbares Teil unterschiedliche Antriebe vorgesehen. Dabei kann die Verstellung der Phasenlage zwischen dem Bodenmacherzylinder und dem rotierbaren Teil über ein unterschiedliche Ansteuerung der Antriebe vornehmbar sein. In dieser Ausführungsform wird die Verwendung von getrieblichen Mitteln vermieden, wodurch die Verschleißanfälligkeit der Beutelmaschine erheblich reduziert wird.In a further embodiment of the invention are for the Bodenmacher cylinder and the rotatable part different drives intended. In this case, the adjustment of the phase angle between the Bodenmacherzylinder and the rotatable part on a different Control of the drives be vornehmbar. In this embodiment, the Using geared means avoided, causing the Susceptibility to wear of the bag machine is significantly reduced.

Weitere Details und Ausführungsbeispiele der vorliegenden Erfindung werden in der gegenständlichen Beschreibung und der Zeichnung offenbart.Further details and embodiments of the present invention will become in the subject description and the drawing.

Figur 1 zeigt eine skizzierte Seitenansicht einer Beutelmaschine 135. Diese Figur wurde eingefügt, um den technischen Hintergrund der erfindungsgemäßen Vorrichtungen zu zeigen. Hierbei geht es in erster Linie um die Beschreibung der Kernfunktion einer solchen Beutelmaschine, die im Bereich der Schlauchabschnittbildung und Bodenmachung besteht. Hierzu wird an dieser Stelle noch einmal angemerkt, dass der Bodenmacherzylinder und der Bodenöffner auch in den deutschen Auslegeschriften 1611699 sowie 1080846 erklärt sind. Der in Figur 1 gezeigten Beutelmaschine wird eine Papierbahn 100 von rechts nach links in der Transportrichtung der Papierbahn beziehungsweise der Beutelbestandteile z zugeführt. In der Schlauchbildungsstation 101, welche die Walzen 102 umfasst, die auch das Transportband 103 führen, wird die Papierbahn zu einem Schlauch 130 zusammengelegt. Dieser Vorgang wird auch durch die Striche 104 symbolisiert, welche die Ränder der Papierbahn bei ihrem Zusammenlegen darstellen. Der fertige Papierschlauch 130 wird dem Abreißwerk 131 zugeführt. Zu diesem Abreißwerk gehören zunächst die Vorzugswalzen 106, welche die Papierbahn führen und die Papierbahnen zwischen gegeneinander in Opposition stehenden Vorzugswalzen arretieren. Nach dem Durchlaufen der Walzenspalte zwischen den Vorzugswalzen wird der Papierschlauch von dem Messer 108, welches an dem rotierenden Messerträger 107 arretiert ist, welcher das Messer entlang der gestrichelten Bahn 107a führt, perforiert. Beim Perforationsvorgang selbst bildet der Gegendruckzylinder 109 eine Gegenlage. An dem Messerträger 107 sind zwei Messer 108 angebracht, so dass bei einer Umdrehung des Messerträgers 107 zwei Querschnitte auf der Schlauchbahn 130 entstehen. Der Gegendruckzylinder 109 vollführt während dieser Zeit zwei Umdrehungen. Der vorperforierte Schlauch kommt sodann in den Walzenspalt zwischen den beiden Abreißzylindern 110, welche schneller laufen als die Vorzugswalzen 106. Dadurch wird der Schlauch an der Perforationsstelle abgerissen, was zwischen dem Messer 108 und dem Walzenspalt zwischen den Abreißzylindern 110 erfolgt. Es bleibt anzumerken, dass der Papierschlauch jetzt zu Papierschlauchabschnitten 112 vereinzelt ist. Diese Papierschlauchabschnitte 112 werden zunächst von den Transportwalzen 111 weiter transportiert. Sie erreichen die Längseinschnittstation 105, bei der zwischen den beiden Walzen 116 ein Längsschnitt in das vordere Ende des Schlauchabschnitts eingebracht wird, was zur anschließenden Bodenbildung notwendig ist. Nach der Längseinschnittstation 105 werden die Schlauchabschnitte der Bodenöffnungsstation 114, welche hauptsächlich aus dem Bodenöffner 113 besteht, zugeführt. Hier werden die Böden geöffnet. Wie bereits erwähnt zeigt die vorgenannte deutsche Auslegeschrift 1611609 einen solchen Bodenöffner. Schließlich werden die Schlauchstücke dem Bodenmacherzylinder 115 zugeführt, der diese übernimmt und an verschiedenen Bearbeitungsstationen, welche um den Bodenmacherzylinder angeordnet sind, vorbeiführt. Die erste dieser Stationen ist die Bodenfaltungs- und -Beleimungsstation 117. Die einzelnen Elemente dieser Station sind nur skizziert dargestellt und können den zitierten Druckschriften entnommen werden. In jedem Fall sind sie dem Fachmann bekannt. Nach Durchlaufen der Bodenfaltungs- und - beleimungsstation werden die Böden in der Bodenschließungsstation fixiert beziehungsweise angepresst. Dieses geschieht hauptsächlich dadurch, dass die Schlauchabschnitte beziehungsweise Beutel zwischen dem Bodenmacherzylinder 115 und einem Pressband 119, welches von den Walzen 125 geführt wird, verpresst werden. Bei der gezeigten Beutelmaschine laufen die Schlauchabschnitte beziehungsweise Beutel 112 dann um einen Umkehrzylinder 120, welcher dafür sorgt, dass sich die Beutel beziehungsweise Schlauchabschnitte weiter von rechts nach links in der Transportrichtung der Beutelbestandteile z bewegen. In der Regel werden die mit fertig gelegten und fixierten Böden versehenen Schlauchabschnitte dann weiteren Bearbeitungsstationen zugeführt. So werden die Beutel oft bedruckt und/oder mit Tragegriffen versehen. An dieser Stelle wird jedoch auf die Darstellung solcher Arbeitsstationen verzichtet. Es wurde ebenfalls darauf verzichtet, die Abwicklungen für die Papierbahn 100, welche der Schlauchbildungsstation 101 vorgelagert sind, zu zeigen.FIG. 1 shows a sketched side view of a bag machine 135 Figure has been added to the technical background of show devices of the invention. This is primarily about the description of the core function of such a bag machine used in the Area of tubing section formation and grounding. For this purpose is at this point once again noted that the Bodenmacherzylinder and the Bodenöffner also in the German Auslegeschriften 1611699 as well 1080846 are explained. The bagging machine shown in FIG. 1 becomes a Paper web 100 from right to left in the transport direction of the paper web or the bag components z supplied. In the Hose forming station 101, which includes the rollers 102, which also includes the Lead conveyor belt 103, the paper web to a tube 130th merged. This process is also symbolized by the lines 104, which represent the edges of the paper web when folded. Of the finished paper tube 130 is fed to the tear-off unit 131. To this Tear-off include initially the preferred rollers 106, which the paper web lead and the paper webs in opposition to each other Lock preferred rollers. After passing through the nips between the preferred rollers of the paper tube from the knife 108, which at the rotating blade carrier 107 is locked, which the knife along the dashed path 107a leads, perforated. Forms itself during the perforation process the counter-pressure cylinder 109 a counter-position. On the knife carrier 107 are two knives 108 attached so that upon one rotation of the knife carrier 107 two cross sections on the tube web 130 arise. Of the Counter-pressure cylinder 109 performs two revolutions during this time. Of the Preperforated hose then enters the nip between the both tear-off cylinders 110, which run faster than the feed rollers 106. As a result, the hose is torn off at the perforation, what between the knife 108 and the nip between the breakaway cylinders 110 takes place. It should be noted that the paper tube now too Paper tube sections 112 is isolated. These paper tube sections 112 are first transported by the transport rollers 111 on. she reach the longitudinal cutting station 105, between the two rollers 116 introduced a longitudinal section in the front end of the hose section becomes what is necessary for subsequent soil formation. After Long incision station 105, the tube sections of Bottom opening station 114, which mainly from the bottom opener 113th exists, supplied. This is where the floors are opened. As already mentioned shows the aforementioned German Auslegeschrift 1611609 such a bottom opener. Finally, the pieces of tubing the Bodenmacherzylinder 115th supplied, which takes these and at various processing stations, which are arranged around the Bodenmacherzylinder passes. The first of these stations is the bottom folding and gluing station 117. The individual elements of this station are only sketched and can the cited references are taken. In any case, they are the Specialist known. After passing through the floor folding and - gluing station, the floors are fixed in the floor closing station or pressed. This happens mainly in that the tube sections or bag between the Bodenmacher cylinder 115 and a press belt 119, which from the rollers 125 is guided, be pressed. Run in the bag machine shown the tube sections or bag 112 then one Reverse cylinder 120, which ensures that the bag or Hose sections continue from right to left in the transport direction of the Move bag components z. In general, those who are finished with and fixed bottoms then hose sections further Supplied processing stations. So the bags are often printed and / or provided with carrying handles. At this point, however, is on the presentation dispensed with such workstations. It was also waived, the Windings for the paper web 100, which of the hose forming station 101 are upstream, to show.

Figur 2 zeigt jedoch noch einmal einen Beutel, wie er in einer solchen Beutelmaschine 135 hergestellt werden kann. Dieser Beutel 123 besitzt Seitenfalten 122.However, Figure 2 shows once again a bag, as in such a Bag machine 135 can be made. This bag 123 has Gussets 122.

Die Figur 3 zeigt einen etwas fortgeschritteneren Beutel 121 mit Tragegriffen 124, welche zusätzlich mit einem Deckblatt 125 an dem Beutel fixiert worden sind. Auch Tragegriffe und die Verfahren und Vorrichtung zu deren Herstellung und der Anbringung am Beutel sind dem Fachmann bekannt und werden beispielsweise in der DE 42 05 062 A1, welche eingangs schon erwähnt wurde, gezeigt. In der Regel bilden solche Tragegriffstationen Bestandteile der Beutelmaschine, welche dem Bodenmacherzylinder nachgelagert sind. Die Traggriffstation kann jedoch auch bereits vor der Schlauchbildungsstation angeordnet sein Figur 6 verdeutlicht auch noch einmal die Gestaltung des Beutels. So ist die Breite und Höhe des Beutels noch einmal dargestellt. Die Höhe des Beutels wird durch die Schlauchabschnittlänge, welche von der Abreißstation definiert wird, bestimmt. Bei der gezeigten Beutelmaschine wird die Höhe des Sackes beziehungsweise die Schlauchabschnittslänge in erster Linie durch den Durchmesser des Umfangkreises des Messerträgers 107 bestimmt. Die Breite ergibt sich aus der Breite der Papierbahn und den Einstellungen der Schlauchlegestation 101. Auch bei Breitenwechseln müssen umfangreiche Änderungen der Einstellungen der Werkzeuge, beispielsweise am Bodenmacherzylinder, vorgenommen werden.FIG. 3 shows a somewhat more advanced bag 121 with carrying handles 124, which has been additionally fixed with a cover sheet 125 to the bag are. Also carrying handles and the method and apparatus for their preparation and the attachment to the bag are known in the art and are for example in DE 42 05 062 A1, which was already mentioned at the beginning, shown. As a rule, such carrying handle stations form part of the Bag machine, which are downstream of the Bodenmacherzylinder. The But carrying handle station can also already before the hose forming station Figur 6 also clarifies once again the design of the Bag. So the width and height of the bag is shown again. The Height of the bag is determined by the length of hose section, which of the Abreißstation is defined determined. In the bag machine shown is the height of the bag or the hose section length in the first Line through the diameter of the circumferential circle of the knife carrier 107th certainly. The width results from the width of the paper web and the Settings of the hose station 101. Even with width changes must extensive changes to the settings of the tools, for example on Bodenmacherzylinder, be made.

Die Figur 4 zeigt einen Ausschnitt der der Bodenstation 117 in einer Detailansicht. Der Antrieb der Bodenfaltungsstation erfolgt durch eine nicht dargestellte Welle, welche ein Umlenkgetriebe 1 mit einem Antriebsdrehmoment versorgt. Dem Umlenkgetriebe vorgelagert sind Ellipsenzahnräder, welche für Geschwindigkeitsdifferenzen im Vergleich zur Geschwindigkeit der Antriebswelle sorgen. Über zwei Zahnräder 2, 3 wird das Drehmoment auf die Welle 4 übertragen, welche wiederum in einem Differentialgetriebe 5 endet. Dieses Differentialgetriebe 5 treibt ein weiteres Zahnrad 6 an. Mithilfe des Differentialgetriebes 5 kann eine Phasenverschiebung zwischen der Welle 4 und dem Zahnrad 6 erreicht werden. Das Zahnrad 6 treibt über ein weiteres Zahnrad 7 die Welle 8 an. Von der Welle 8 wird Drehmoment von dem Umlenkgetriebe 9 auf das rotierbare Teil, welches als Blech 10 ausgeführt ist, übertragen. Dieses Blech 10, welches sichelförmig ausgebildet sein kann, wird dadurch in Rotation versetzt. Aufgrund der zeitweise höheren Rotationsgeschwindigkeiten während eines Umlaufs im Vergleich zur Rotationsgeschwindigkeit der Antriebswelle ist das Blech 10 in der Lage, die Bodenklappe in Transportrichtung des Schlauchstücks umzuklappen. Das Umlenkgetriebe 9 ist an einem Träger 11 befestigt. Dieser Träger 11 ist in Richtung des Doppelpfeiles A in Richtung der Schiene 12 verschieblich gelagert. Auf diese Weise kann der Schließmechanismuss, bestehend aus dem Umlenkgetriebe 9 und dem Blech 10 auf die Breite des Schlauchstückes eingestellt werden, ohne das Blech austauschen zu müssen.

The drive of the bottom folding station is effected by a shaft, not shown, which supplies a deflection gear 1 with a drive torque. The deflection gear is preceded by elliptical gears, which provide for differences in speed compared to the speed of the drive shaft. About two gears 2, 3, the torque is transmitted to the shaft 4, which in turn ends in a differential gear 5. This differential gear 5 drives another gear 6. By means of the differential gear 5, a phase shift between the shaft 4 and the gear 6 can be achieved. The gear 6 drives the shaft 8 via another gear 7. From the shaft 8 torque from the reversing gear 9 on the rotatable part, which is designed as a sheet 10, transmitted. This sheet 10, which may be sickle-shaped, is thereby set in rotation. Due to the temporarily higher rotational speeds during a revolution compared to the rotational speed of the drive shaft, the sheet 10 is able to fold down the bottom flap in the transport direction of the hose piece. The deflection gear 9 is fixed to a carrier 11. This carrier 11 is slidably mounted in the direction of the double arrow A in the direction of the rail 12. In this way, the closing mechanism, consisting of the deflection gear 9 and the sheet 10 can be adjusted to the width of the hose piece without having to replace the sheet.
