Description

Die vorliegende Erfindung betrifft eine Verwendung einer Schneidvorrichtung und ein Verfahren zum Schneiden von vorgefertigten Quersiegelnähten eines mit Lebensmittel, insbesondere mit Schmelzkäse, gefüllten Schlauches aus Kunststofffolie, wobei jede Quersiegelnaht des zu bearbeitenden und kontinuierlich zugeführten Folienschlauches eine Portion des Lebensmittels von der nächsten Portion trennt, wobei die Vorrichtung eine rotierende und mit mindestens einer Messerklinge bestückte Messerhalterung, insbesondere in Form einer Messerwalze, aufweist und wobei die Messerklinge beim Schneiden einer Quersiegelnaht ein Gegenlager, insbesondere eine gegenläufige Gegenwalze, beaufschlagt.The present invention relates to a use of a cutting device and a method for cutting prefabricated transverse sealing seams of a plastic film filled with food, in particular processed cheese, wherein each transverse seam of the film tube to be processed and continuously fed separates a portion of the food from the next portion the device has a rotating knife holder equipped with at least one knife blade, in particular in the form of a knife roll, and wherein the knife blade acts upon an abutment, in particular a counter-rotating counter roll, when cutting a transverse seam.

Derartige Schneidvorrichtungen sind beispielsweise aus der Herstellung einzeln verpackter Schmelzkäsescheiben bekannt. Ein solches Verfahren zur Herstellung und die entsprechende Vorrichtung sind beispielsweise in der DE 42 04 357 A1 gezeigt. Dabei wird geschmolzener Käse in einen an einer Längsnaht versiegelten Folienschlauch gefüllt, der dann flach gewalzt und nachfolgend gekühlt wird. In diesem Fall wird das von Folie umgebene Käseband erst nach dem Kühlen ("Kaltverdrängen") portioniert, indem der Käse an Querstreifen verdrängt und der vom Käse befreite Folienschlauch an diesen Querstreifen durch Hitzeeinwirkung versiegelt wird. Dieses Verdrängen geschieht bei modernen Maschinen schon, solange die Käsemasse noch heiß ist ("Heißverdrängen"). Um aus dieser "Kette" respektive diesem Band aneinander hängender Scheiben einzelne Scheiben zu machen, werden die einige Millimeter breiten, von den Quersiegelungen gebildeten Nähte mit dem oder den Messern der Schneidvorrichtung durchtrennt. Dabei können derartige Schneidvorrichtungen in der Art von Guillotinen ausgebildet sein. Als besonders vorteilhaft hat sich jedoch der Einsatz von Messerwalzen erwiesen, deren federnde Messerklingen auf der gehärteten Oberfläche einer Gegenwalze schneiden, wobei die Kette der Einzelscheiben durch die beiden Walzen hindurch geführt wird. Eine ähnliche Vorrichtung ist auch aus der EP 0 887 273 A1 bekannt.Such cutting devices are known, for example, from the production of individually packaged melted cheese slices. Such a method for the production and the corresponding device are for example in the DE 42 04 357 A1 shown. Here, molten cheese is filled in a sealed at a longitudinal seam film tube, which is then rolled flat and then cooled. In this case, the cheese strip surrounded by film is portioned only after cooling ("cold-rolling") by displacing the cheese to horizontal stripes and the foil-free tube of the cheese is heat-sealed to these transverse strips. This displacement is already happening in modern machines, as long as the cheese mass is still hot ("Heißverdrängen"). In order to make individual disks out of this "chain" or band of disks hanging from each other, the seams, which are a few millimeters wide and formed by the transverse seals, are severed with the blade (s) of the cutting device. In this case, such cutting devices may be designed in the manner of guillotines. Particularly advantageous, however, the use of knife rollers has proven to cut the resilient knife blades on the hardened surface of a backing roll, the chain of individual discs is passed through the two rollers. A similar device is also from the EP 0 887 273 A1 known.

Ein Nachteil der bekannten Schneidvorrichtungen ist, dass die Messerklingen nach einer bestimmten Anzahl von Schnitten stumpf werden und ausgewechselt werden müssen. Das rührt daher, dass die doppellagige meist aus Polypropylen bestehende Folie einer Stärke von etwa 50 Mikrometern in dem zu schneidenden Zustand verhältnismäßig zäh ist. Das Abstumpfen der Messerklingen beeinflusst die Standzeit negativ und mindert die Produktivität der Maschine. Zudem sind die auszutauschenden Messerklingen an sich ein Kostenfaktor, zu dem die Montage mit der aufwendigen Justierung hinzukommt.A disadvantage of the known cutting devices is that the knife blades after a certain number of cuts become dull and must be replaced. This is due to the fact that the double-layer film, which is mostly made of polypropylene and has a thickness of about 50 micrometers, is relatively tough in the state to be cut. The blunting of the knife blades negatively affects the service life and reduces the productivity of the machine. In addition, the knife blades to be replaced are in themselves a cost factor, to which the assembly with the elaborate adjustment added.

Aufgabe der Erfindung ist es nunmehr bei einem einfachem Aufbau eine wegen geringerer Abnutzung der Messerklingen verlängerte Standzeit zu gewährleisten.The object of the invention is now to ensure a prolonged service life due to less wear of the knife blades with a simple structure.

Diese Aufgabe wird durch die die Verwendung einer Schneidvorrichtung nach Anspruch 1 und das Verfahren zum Schneiden nach Anspruch 12 gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen genannt.This object is achieved by the use of a cutting device according to claim 1 and the method of cutting according to claim 12. Advantageous embodiments are mentioned in the subclaims.

Ein wesentlicher Grundgedanke der Erfindung liegt darin, die Messerhalterung mit einem Heizelement zu versehen, das eine gezielte Erwärmung der Messerklinge verursacht. Dabei ist als "gezielte Erwärmung der Messerklinge" eine solche Erwärmung gemeint, die über die normale Betriebstemperatur der Messerklinge hinausgeht und die vor allem nicht zu einer bemerkenswerten Erwärmung der Messerhalterung führt, die aufgrund von Wärmeausdehnung deren Geometrie im Hinblick auf ihre reibungslose Funktion unbehebbar verändern würde. Die erfindungsgemäße Erwärmung ist insbesondere auch nicht so stark, dass die Folie an der Quersiegelnaht durch Schmelzen geöffnet wird. Die Temperatur der Messerklinge bleibt demach unterhalb der Schmelztemperatur des für die Folie verwendeten Kunststoffes.An essential basic idea of the invention is to provide the knife holder with a heating element that causes a targeted heating of the knife blade. It is meant as a "targeted heating of the knife blade" such a warming that goes beyond the normal operating temperature of the knife blade and especially does not lead to a remarkable heating of the knife holder, due to thermal expansion of their geometry in With regard to their smooth functioning would be irreversible. The heating according to the invention is in particular not so strong that the film is opened at the transverse sealing seam by melting. The temperature of the knife blade remains below the melting temperature of the plastic used for the film.

An dieser Stelle sei hervorgehoben, dass sich die erfindungsgemäße Vorgehensweise von dem Stand der Technik, wie er beispielsweise in der DE 39 20 867 A1 offenbart ist, unterscheidet. Dort wird in einem einzigen Arbeitsschritt das Produkt dem zu schneidenden Bereich des Schlauches verdrängt, dieser Bereich querversiegelt und dabei geschnitten. Das Messer führt somit zugleich ein Verschließen und Trennen durch. Es existiert an keiner Stelle die vorgefertigte Quersiegelnaht. Somit ist diese Vorgehensweise bei dem hier vorliegenden mit Lebensmittel, insbesondere mit Schmelzkäse, gefüllten Schlauch nicht möglich, da im Verarbeitungsprozess zunächst eine Kette zusammenhängender Portionen gebildet und einer Kühlung zugeführt werden muss. Erst die so vorverarbeiteten Portionen werden dann vereinzelt.At this point it should be emphasized that the procedure according to the invention of the prior art, as it is for example in the DE 39 20 867 A1 disclosed differs. There, the product is displaced in a single step, the area to be cut of the hose, this area transversely sealed and thereby cut. The knife thus simultaneously performs a closing and separating. At no point does the prefabricated transverse seam exist. Thus, this procedure is not possible with the present here with food, especially with processed cheese, filled hose, since in the processing process, first a chain of contiguous portions must be formed and fed to a cooling. Only the thus preprocessed portions are then separated.

Bei der erfindungsgemäßen zusätzlichen Erwärmung gilt es, diese möglichst von den Lagern fern zu halten. Dieses Ziel kann dadurch erreicht werden, dass die Messerhalterung an sich so konzipiert ist, dass der Wärmefluss im Wesentlichen an die Messerklinge geleitet wird. Dies kann durch die Materialwahl oder das Vorsehen von Isolierungen und/oder das Einrichten einer Wärmefalle, beispielsweise in Form einer Kühlung durch eine entsprechende Kühleinrichtung, beeinflusst werden. Besonders vorteilhaft, da besonders einfach zu realisieren ist es jedoch, wenn das Heizelement derart in der Nähe der Messerklinge und mit entsprechendem Wärmekontakt zur Messerklinge angeordnet ist, dass ein Großteil der Heizleistung der Messerklinge möglichst direkt zugeführt wird und diese stärker als die restliche Messerhalterung erwärmt.In the additional heating invention, it is important to keep them away from the camps as possible. This goal can be achieved by the fact that the knife holder itself is designed so that the heat flow is essentially passed to the knife blade. This can be influenced by the choice of material or the provision of insulation and / or the establishment of a heat trap, for example in the form of cooling by a corresponding cooling device. Particularly advantageous, since it is particularly easy to implement, however, when the heating element is arranged in the vicinity of the knife blade and with appropriate thermal contact with the knife blade, that a large part of the heating power of the knife blade is fed directly as possible and this heated more than the rest of the knife holder.

Generell liegt der Vorteil der Erwärmung der Messerklinge darin, dass der lokal kurzzeitig erwärmte Folienschlauch der Messerklinge beim Schneiden einen verminderten Widerstand entgegensetzt, so dass der Grad der Abnutzung der Messerklinge verringert und damit die Standzeit der Schneidvorrichtung erhöht wird. Schließlich wird der aus Kunststofffolie, beispielsweise aus Polypropylen, gebildete Folienschlauch durch die Erwärmung an der Schnittstelle weicher, als er bei Raumtemperatur ist, so dass er sich leichter schneiden lässt. Es hat sich gezeigt, dass sich die Standzeit der Messerklingen auf die erfindungsgemäße Weise um ein Vielfaches erhöhen lässt. Dabei hat sich auch herausgestellt, dass es vorteilhaft ist, wenn die Heizleistung und die Anordnung des Heizelementes so gewählt wird, dass an der Schneidkante der Messerklinge eine Temperatur von über 80°C, insbesondere von etwa 100°C, erzeugt wird. Temperaturen von bis zu 130°C sind nicht ausgeschlossen.In general, the advantage of heating the knife blade is that the local briefly heated film tube of the knife blade during cutting opposes a reduced resistance, so that the degree of wear of the Reduced knife blade and thus the life of the cutting device is increased. Finally, the film tube formed of plastic film, such as polypropylene, becomes softer when heated at the interface than it is at room temperature, so that it is easier to cut. It has been found that the service life of the knife blades can be increased many times in the manner according to the invention. It has also been found that it is advantageous if the heating power and the arrangement of the heating element is selected so that at the cutting edge of the knife blade a temperature of about 80 ° C, in particular of about 100 ° C, is generated. Temperatures of up to 130 ° C are not excluded.

Als Heizelement kann beispielsweise eine kommerziell erhältliche Heizpatrone ausreichender Größe eingesetzt werden, die in eine in der Messerhalterung eingebrachte Bohrung gehalten und über eine Spannung versorgt wird. Die Dimensionierung der Heizpatrone und deren Spannungsversorgung ist entsprechend der Geometrie der Messerhalterung anzupassen. Die Heizleistung der Heizpatronen kann der Anlagengeschwindigkeit angepasst werden, um die gewünschte Temperatur zu erhalten. Auch wenn die Messung der aktuellen Temperatur durch einen entsprechenden Sensor und auch deren Regelbarkeit von einem gewissen Vorteil ist, so ist sie nicht unbedingt nötig. Schließlich schneidet die Schneidvorrichtung "im Notbetrieb" auch ohne beheizte Messerklinge.As a heating element, for example, a commercially available heating cartridge of sufficient size can be used, which is held in an introduced in the knife holder bore and powered by a voltage. The dimensioning of the heating cartridge and its power supply must be adjusted according to the geometry of the blade holder. The heating capacity of the heating cartridges can be adapted to the system speed to obtain the desired temperature. Even if the measurement of the current temperature by a corresponding sensor and its controllability of a certain advantage, it is not absolutely necessary. Finally, the cutting device cuts "in emergency mode" even without a heated knife blade.

Da es konstruktiv aufwendig ist, unerwünschte Wärmeausdehnungen, die die Lage der Messerklinge verändern, zu minimieren und sich solche Veränderungen mitunter nicht vollständig vermeiden lassen, ist es besonders vorteilhaft, wenn die Messerklinge federnd an der Messerhalterung gehalten ist, so dass ein Federn der Messerklinge in Schneidrichtung möglich ist. Dabei ist die Federkraft so einzustellen, dass ein für die Schneidwirkung ausreichender Druck erhalten bleibt. Die erfindungsgemäße Federung kann sich dabei aus der Messerklinge selbst oder über ein federnd aufgehängtes Aufnahmeteil, in dem die Messerklinge gehalten ist, ergeben. Tatsächlich ist die Idee der Querschneidvorrichtung mit federnd aufgehängter Messerklinge gewissermaßen unabhängig von der erfindungsgemäßen Messerhalterung mit Heizelement. Allerdings ergeben sich gerade aus der Kombination der beiden Ideen besondere Vorteile.Since it is structurally complex to minimize unwanted thermal expansions that change the position of the knife blade, and sometimes can not be completely avoided, it is particularly advantageous if the knife blade is resiliently held on the knife holder, so that springs of the knife blade in Cutting direction is possible. The spring force must be adjusted so that a sufficient pressure for the cutting action is maintained. The suspension according to the invention can be obtained from the knife blade itself or via a spring-mounted receiving part in which the knife blade is held. In fact, the idea of the cross-cutting device with spring-suspended knife blade is effectively independent of the knife holder according to the invention with heating element. However, the combination of the two ideas offers particular advantages.

Ein Vorteil einer solchen Federung liegt vor allem in der damit einhergehenden Erhöhung der Toleranz der Messerklinge gegenüber einer eventuellen Dejustierung, die beim Betrieb geschehen kann. Dieser Vorteil kommt besonders dann zum Tragen, wenn die Messerhalterung und das Gegenlager als Walzen ausgebildet sind und die Messerklinge sich beim Schnitt exakt gegen die glatte und gehärtete Oberfläche der Gegenwalze anlegen muss. Bei einer solchen Anordnung erzeugt jede Dejustierung einen Spalt zwischen der Messerklinge und der Oberfläche der Gegenwalze, so dass der Schnitt nicht vollständig durchgeführt werden kann. Mit der erfindungsgemäßen gefederten Aufhängung, die vorteilhafterweise auch noch ein kleines Spiel in anderen Freiheitsgraden zulässt, wird eine solche Spaltbildung vermieden. Dadurch, dass die Federung eine gewisse Toleranz gegen Dejustierung bewirkt, reduziert sich auch der Aufwand bei der Montage der Messerklingen.An advantage of such a suspension is above all in the associated increase in the tolerance of the knife blade against a possible maladjustment that can occur during operation. This advantage is particularly useful if the knife holder and the counter bearing are designed as rollers and the knife blade must create exactly when cutting against the smooth and hardened surface of the backing roll. With such an arrangement, each misalignment creates a gap between the knife blade and the surface of the backing roll so that the cut can not be completed. With the sprung suspension according to the invention, which advantageously also allows a small clearance in other degrees of freedom, such a gap formation is avoided. The fact that the suspension causes a certain tolerance against misalignment, also reduces the effort during assembly of the knife blades.

Im Hinblick auf eine besonders hohe Fertigungsgeschwindigkeit ist es vorteilhaft, wenn die Messerhalterung als rotierendes Mittel, insbesondere in Form der schon erwähnten Messerwalze ausgebildet ist, wobei diese insbesondere mit mehreren, vorteilhafterweise mit vier Messerklingen, bestückt ist. Im Fall eines solchen Messerwalze ist es dann vorteilhaft, wenn das Gegenlager von einer gegenläufigen Gegenwalze, die insbesondere eine Oberfläche aus Hartmetall hat, gebildet wird. Die Gegenwalze kann einen etwas anderen Durchmesser als die Messerwalze haben. Um einen weiteren Antrieb einzusparen, ist es besonders vorteilhaft, wenn die Messerwalze die Gegenwalze über aufeinander abrollende Randbereiche antreibt. Über ein solcher mit geringem Schlupf behafteten Antrieb oder über etwas unterschiedliche Walzendurchmesser wird bewirkt, dass die Messerklinge nicht immer dieselbe Stelle des Gegenlagers beaufschlagt, so dass es zu einer gleichmäßigen Abnutzung des Gegenlagers kommt. Vorteilhafterweise ist das Lager der Gegenwalze auch etwas vorgespannt, um den entsprechenden Anpressdruck zu erzeugen und um Toleranzen auszugleichen.With regard to a particularly high production speed, it is advantageous if the knife holder is designed as a rotating means, in particular in the form of the already mentioned knife roller, which is in particular equipped with several, advantageously with four knife blades. In the case of such a knife roller, it is advantageous if the counter-bearing is formed by an opposing counter-roller, which in particular has a surface made of hard metal. The counter roll may have a slightly different diameter than the knife roll. In order to save a further drive, it is particularly advantageous if the knife roller drives the counter roller over successive rolling edge regions. About such a low-slip drive or a slightly different roller diameter causes the knife blade is not always applied to the same point of the thrust bearing, so that it comes to a uniform wear of the thrust bearing. Advantageously, the bearing of the backing roll is also biased slightly to produce the corresponding contact pressure and to compensate for tolerances.

Im Falle einer solchen Messerwalze gibt zwei vorteilhafte Möglichkeiten, die Messerklingen zu haltern: In dem einen Fall wird die Aufnahme für eine Messerklinge von einem separaten Aufnahmeteil ausgebildet, das in einer radial ausgerichteten Führung in der Messerwalze gehalten und von Federn beaufschlagt ist. Eine solche Konstruktion bietet zwar mehr Möglichkeiten bezüglich der Einstellungsparameter, doch ist die Justierung schon wegen der hohen Anzahl von Teilen aufwendig. In einer besonders einfachen Alternative, bildet das Material der Messerwalze die Anlageflächen selber aus. Die Anlageflächen sind gewissermaßen in das Material der Messerwalze eingelassen, wobei entsprechend justierende Anlagekanten vorgesehen sein können. Die Messerklingen brauchen dann nur an diese Anlageflächen angesetzt und befestigt zu werden. Um eine Federung zu erhalten, sind die Anlageflächen etwas kürzer als die Messerklingen, so dass diese mit ihrem Überstand bei entsprechender Halterung federn.In the case of such a knife roller are two advantageous ways to support the knife blades: In the one case, the receptacle for a knife blade is formed by a separate receiving part which is held in a radially oriented guide in the knife roller and acted upon by springs. Although such a design offers more options in terms of setting parameters, but the adjustment is already complicated because of the high number of parts. In a particularly simple alternative, the material of the knife roller forms the contact surfaces themselves. The contact surfaces are admitted to some extent in the material of the knife roller, which may be provided correspondingly adjusting abutment edges. The knife blades then need only be attached to these contact surfaces and fastened. In order to obtain a suspension, the contact surfaces are slightly shorter than the knife blades, so that they feather with their supernatant with appropriate support.

Vorteilhafterweise wird die Quersiegelung beim Schnitt nicht völlig durchtrennt, sondern gewissermaßen perforiert, so dass nach dem Schnitt Folienstege verbleiben, an denen die Kette zusammen hält und noch ein Stück bis zur endgültigen Abtrennung der einzelnen Glieder weiter befördert werden kann. Das endgültige Abtrennen geschieht dann beispielsweise durch Abreißen, indem die vorlaufende Portion, insbesondere die Käsescheibe, im Verhältnis zur nachlaufenden etwas beschleunigt wird. Eine solche "Perforierung" kann dadurch erzeugt werden, dass die Schnittkante der Messerklinge kürzer als die Quersiegelnaht ist, so dass beim Schnitt zwei Stege am Rand stehen bleiben. Um diese Perforierung zu erreichen, können auch Nuten in die Messerklingen eingeschliffen werden.Advantageously, the transverse seal is not completely severed during the cut, but perforated as it were, so that after the cut Folienstge remain, where the chain holds together and can be transported a piece until the final separation of the individual elements on. The final separation is done for example by tearing off by the leading portion, in particular the cheese slice, in relation to the trailing something is accelerated. Such a "perforation" can be generated in that the cutting edge of the knife blade is shorter than the transverse seal, so that two webs stop at the edge when cutting. To achieve this perforation, grooves can also be ground into the knife blades.

Besonders vorteilhaft ist es auch, wenn die Messerwalze und die Gegenwalze in einem gemeinsamen Modul zusammengefasst werden, das leicht auswechselbar an der Maschine gehalten ist. Ein solches Modul hat den Vorteil, dass die Messerklingen vormontiert und justiert werden können. Um die Austauschbarkeit zu ermöglichen, wird die Messerwalze mit einer in der Antriebswelle angeordneten elektrischen Steckverbindung ausgestattet, über die die Versorgungsleitungen des oder der Heizelemente mit entsprechenden, in der Welle verlaufenden Kabeln kontaktiert werden können.It is also particularly advantageous if the knife roller and the counter roller are combined in a common module, which is held easily replaceable on the machine. Such a module has the advantage that the knife blades can be preassembled and adjusted. In order to enable the interchangeability, the knife roller is arranged with a in the drive shaft equipped electrical connector, via which the supply lines of the heating elements or with corresponding, running in the shaft cables can be contacted.

The invention will be described below with reference to FIG FIGS. 1 to 4 explained in more detail. It shows
  • FIG. 1 a section through the cross-cutting device used in the invention,
  • FIG. 2 : A cross cutting module with knife roll and counter roll,

Der in Figur 1 dargestellte Schnitt durch eine Querschneidvorrichtung zeigt an seinem Ende ein Querschneidmodul 1 (siehe auch Figur 2), mit einer (geschnitten dargestellten) als Querschneidzylinder ausgebildeten rotierenden Messerwalze 2 und einer Gegenwalze 4, deren Oberfläche 3 mit Hartmetall belegt ist. Die von den zusammenhängenden Käsescheiben gebildete Kette wird von oben an einem Leitblech 17 vorbei zwischen die Walzen geführt. Das Querschneidmodul 1 ist an einer Montagewand 5 der Maschine festgeschraubt. In Figur 1 zu erkennen ist zudem der Antrieb der Messerwalze 2 über die Antriebswelle 6, in deren zentralen Bohrung 7 nicht dargestellte Kabel für die Versorgung von Heizelementen geführt sind. Der Antrieb geschieht über einen nicht dargestellten Servomotor, der über das Schneckengetriebe 8 auf die Antriebswelle 6 wirkt. Das Schneckengetriebe 8 ist über ein Distanzstück 9 an der Montagewand 5 gehalten, wobei die Antriebswelle 6 in der Montagewand 5 über ein Kugellager 10 gelagert ist.The in FIG. 1 shown section through a cross-cutting device shows at its end a transverse cutting module 1 (see also FIG. 2 ), with a (shown cut) designed as a cross-cutting cylinder rotating knife roller 2 and a counter-roller 4, the surface 3 is covered with carbide. The chain formed by the coherent cheese slices is passed from above to a guide plate 17 between the rollers. The cross cutting module 1 is screwed to a mounting wall 5 of the machine. In FIG. 1 can be seen also the drive of the knife roller 2 via the drive shaft 6, in the central bore 7, not shown cables for the supply of heating elements are performed. The drive is done via a servomotor, not shown, which acts on the drive shaft 6 via the worm gear 8. The worm gear 8 is held by a spacer 9 on the mounting wall 5, wherein the drive shaft 6 is mounted in the mounting wall 5 via a ball bearing 10.

Das Ende der Antriebswelle 6 hat eine Bohrung mit Keilnabenprofil, in die ein entsprechendes Keilwellenprofil 11 der Messerwalze 2 (s. Figur 3) eingesteckt ist. Am Gehäuse des Schneckengetriebes 8 ist eine Halterung 12 für einen Initiator vorgesehen, der die Nocken 13 der Kupplung 14 abfragt und somit die Position der Messerklingen definiert. Die Versorgungsspannung für die Heizelemente wird über eine Schleifringeinheit 15 zugeführt und über die nicht dargestellten Versorgungskabel der Messerwalze 2 zugeführt. In Figur 1 weiter zu erkennen, ist eine Lichtschrankeneinrichtung 18, mit der die Ankunft einer Quersiegelnaht detektiert wird. Entsprechend dieser Ankunft wird der Servomotor so gesteuert, dass die Messerklingen die Quersiegelnaht mittig durchtrennen.The end of the drive shaft 6 has a bore with spline profile, in which a corresponding spline 11 of the knife roller 2 (s. FIG. 3 ) is inserted. On the housing of the worm gear 8 is a holder 12 for an initiator provided, which interrogates the cam 13 of the clutch 14 and thus defines the position of the knife blades. The supply voltage for the heating elements is supplied via a slip ring unit 15 and fed via the supply cable, not shown, of the knife roller 2. In FIG. 1 to further recognize is a light barrier device 18, with the arrival of a transverse seal seam is detected. According to this arrival, the servo motor is controlled so that the knife blades cut through the transverse sealing seam in the middle.

In Figur 2 ist ein separates Querschneidmodul 1 mit einer Messerwalze 2 und einer gegenläufigen Gegenwalze 3 dargestellt. Zu erkennen ist das Keilwellenprofil 11 der Messerwalze 2 und der darin befindliche elektrische Steckkontakt 19. Die Steckverbindung zur Antriebswelle schafft somit die mechanische und die elektrische Kopplung des Querschneidmoduls 1 zum Antrieb. Mit der Steckverbindung kann das komplette Querschneidmodul von der Anlage abgenommen und durch ein anderes ersetzt werden. Der Antrieb der Gegenwalze 3 geschieht über die aufeinander abrollenden Ränder 20 und 21 der beiden Walzen 2 und 3. Aus Figur 2 ersichtlich ist auch eine von vier Messerklingen 22, die an der Messerwalze 2 gehalten sind.In FIG. 2 a separate cross-cutting module 1 with a knife roller 2 and an opposite counter-roller 3 is shown. The spline profile 11 of the knife roller 2 and the electrical plug-in contact 19 located therein can be seen. The plug connection to the drive shaft thus provides the mechanical and the electrical coupling of the transverse cutting module 1 to the drive. With the plug connection, the complete cross cutting module can be removed from the system and replaced by another one. The drive of the counter roll 3 is done via the successive rolling edges 20 and 21 of the two rollers 2 and 3. Off FIG. 2 also visible is one of four knife blades 22 which are held on the knife roller 2.

Besser ersichtlich sind die Messerklingen 22 aus Figur 3, die eine Messerwalze 2 zeigt. In dieser Ausführungsform sind in der Messerwalze 2 separate Aufnahmeteile 23 (Figur 3b) angeordnet, die jeweils eine sich über die gesamte aktive Länge der Messerwalze 2 erstreckenden Messerklinge 22 aufnehmen. Die Messerklingen 22 werden über Schrauben 25 gehalten und im Aufnahmeteil justiert. Die Aufnahmeteile 23 haben jeweils eine Anlagefläche, an der die Messerklinge flächig und mit gutem Wärmekontakt anliegt. Sie sind in einer in das Vollmaterial der Walze 2 eingebrachten Führung geführt und darin in radialer Richtung beweglich. Von Federn 24 werden die Aufnahmeteile 23 in radialer Richtung beaufschlagt. So ist die jeweilige Messerklinge in Schneidrichtung federnd an der Messerhalterung gehalten.The knife blades 22 are better visible FIG. 3 showing a knife roller 2. In this embodiment, in the knife roller 2 separate receiving parts 23 (FIG. FIG. 3b ), each receiving a knife edge 22 extending over the entire active length of the knife roller 2. The knife blades 22 are held by screws 25 and adjusted in the receiving part. The receiving parts 23 each have a contact surface on which the knife blade rests flat and with good thermal contact. They are guided in a guided in the solid material of the roller 2 guide and movable therein in the radial direction. Of springs 24, the receiving parts 23 are acted upon in the radial direction. Thus, the respective knife blade is held resiliently in the cutting direction on the knife holder.

In Figur 3b sind Bohrungen 26 zu erkennen, die in die Aufnahmeteile 23 eingebracht sind und die jeweils ein Heizelement zur gezielten Erwärmung derIn FIG. 3b are holes 26 can be seen, which are introduced into the receiving parts 23 and each having a heating element for the targeted heating of

Messerklinge 22 aufnehmen. Auf diese Weise ist das Heizelement derart angeordnet, dass ein Großteil seiner Heizleistung der Messerklinge 22 zugeführt wird und diese stärker als die Messerhalterung erwärmt.Record knife blade 22. In this way, the heating element is arranged such that a large part of its heating power of the knife blade 22 is supplied and this heated more than the knife holder.

In Figur 4 ist eine andere Art der Messerwalze 2 gezeigt, die auch ein Keilwellenprofil 11 und einen Stecker 19 aufweist, die aber eine andere Art der Anbringung der Messerklingen 22 hat. Insbesondere aus Figur 4b ist ersichtlich, dass die Messerklingen 22 in der Ebene einer Sekante senkrecht zum Radius der Walze angebracht sind. Dazu sind im Vollmaterial der Messerhalterung Anlageflächen 27 ausgebildet, an denen die flächig Messerklingen 22 anliegen. Sie sind an Anlagekanten am Vollmaterial angelegt und werden durch Spannpratzen 28 an ihrer der Schneidkante 29 abgewandten Kante gehalten. In das Material der Walze sind in unmittelbarer Nähe der Anlageflächen 27 Bohrungen 30 zur Aufnahme der Heizelemente eingebracht. Die Messerklingen 22 werden von Flachmaterial aus Hartmetall mit rechteckigem Querschnitt gebildet, wobei die vier Kanten das Flachmaterials jeweils eine Schnittkante ausbilden. Eine Messerklinge weist somit vier Schneiden auf. Das Flachmaterial kann auch aus HSS oder pulvermetallurgischem Material sein.In FIG. 4 is another type of knife roller 2 is shown, which also has a spline 11 and a connector 19, but has a different way of attaching the knife blades 22. In particular from FIG. 4b It can be seen that the knife blades 22 are mounted in the plane of a secant perpendicular to the radius of the roller. For this purpose, contact surfaces 27 are formed in the solid material of the knife holder, against which the flat knife blades 22 abut. They are applied to abutment edges on the solid material and are held by clamping claws 28 at its edge facing away from the cutting edge 29. In the material of the roller 27 bores 30 are introduced for receiving the heating elements in the immediate vicinity of the contact surfaces. The knife blades 22 are formed of flat material made of hard metal with a rectangular cross-section, wherein the four edges of the sheet each forming a cutting edge. A knife blade thus has four cutting edges. The sheet may also be made of HSS or powder metallurgical material.

Die Federung der Messerklingen 22 wird über die einseitige Halterung und die nicht komplette Auflage auf der Anlagefläche 27 gewährleistet. Wegen dieser speziellen Halterung ist eine Federung in Richtung des Pfeils A und damit auch in radialer Schneidrichtung gegeben. Die Laufrichtung ist mit Pfeil B gekennzeichnet.The suspension of the knife blades 22 is ensured by the one-sided support and the non-complete support on the contact surface 27. Because of this special bracket is a suspension in the direction of arrow A and thus given in the radial cutting direction. The running direction is marked with arrow B.
