Description
Die Erfindung betrifft eine Palettenwelle, insbesondere für Etikettiermaschinen, die mit einer Kunststoffumspritzung versehen ist.The invention relates to a pallet shaft, in particular for labeling machines, which is provided with a plastic extrusion.
Aus dem bisherigen Stand der Technik sind Palettenwellen auch zur Verwendung bei Etikettiermaschinen bekannt.From the prior art pallet shafts are also known for use in labeling machines.
So offenbart die
Auch die
Die
Insgesamt werden die verwendeten Palettenwellen häufig als Vollwellen oder als dickwandige Hohlwellen ausgestaltet, um eine hinreichende Festigkeit und Biegesteifigkeit zu ermöglichen.Overall, the pallet shafts used are often designed as solid shafts or thick-walled hollow shafts to allow sufficient strength and flexural rigidity.
Der Erfindung liegt daher die Aufgabe zugrunde, Palettenwellen zur Verfügung zu stellen, die trotz hoher Biegesteifigkeit eine geringere Masse aufweisen. Ferner ist es Aufgabe der Erfindung, eine Etikettiermaschine, die eine oder mehrere Etikettenpaletten umfasst, mit leichteren aber dennoch stabilen Palettenwellen auszustatten.The invention is therefore based on the object to provide pallet shafts available that have a lower mass despite high bending stiffness. It is another object of the invention to provide a labeling machine comprising one or more label pallets, with lighter but stable pallet shafts.
Diese Aufgabe wird durch die Palettenwelle für eine Etikettiermaschine nach Anspruch 1 gelöst. Die Unteransprüche beinhalten zweckmäßige Ausgestaltungen der Palettenwelle.This object is achieved by the pallet shaft for a labeling machine according to claim 1. The subclaims include expedient embodiments of the pallet shaft.
Ferner wird durch die Etikettiermaschine nach Anspruch 10 eine Vorrichtung zum Etikettieren von Behältern, wie Flaschen, mit gewichtsreduzierten aber dennoch stabilen Palettenwellen bereitgestellt.Further provided by the labeling machine according to claim 10, an apparatus for labeling containers, such as bottles, with weight-reduced but stable pallet shafts.
Die erfindungsgemäße Palettenwelle zeichnet sich dadurch aus, dass sie eine Zentralstange umfasst, die von einer Kunststoffumspritzung umgeben ist. Das Umspritzen einer Zentralstange mit Kunststoff, beispielsweise faserverstärktem Kunststoff, kann die Biegesteifigkeit erhöhen und bedeutet gleichzeitig eine Verringerung der Masse, verglichen mit einer Palettenwelle gleichen Umfangs, die vollständig aus Metall besteht. Ebenso gestattet die Kunststoffumspritzung eine zusätzliche Verstärkung von Verbindungen der Zentralstange mit anderen Bauteilen.The pallet shaft according to the invention is characterized in that it comprises a central rod which is surrounded by a plastic extrusion. Injecting a central rod with plastic, such as fiber reinforced plastic, can increase the flexural rigidity and at the same time reduce the mass compared to a pallet shaft of the same circumference made entirely of metal. Likewise, the plastic extrusion allows additional reinforcement of connections of the central rod with other components.
Erfindungsgemäß ist die Palettenwelle dadurch gekennzeichnet, dass an dem einen Ende der Zentralstange eine Metallscheibe, die an der Zentralstange befestigt ist, in die Kunststoffumspritzung eingearbeitet ist. Die Metallscheibe kann dazu genutzt werden, die mechanische Festigkeit einer eventuell an diesem Ende angebrachten Verzahnung zu erhöhen. Durch das Einarbeiten der Metallscheibe in die Kunststoffumspritzung wird darüber hinaus die Befestigung der Metallscheibe an die Zentralstange unterstützt und die Wahrscheinlichkeit, dass es zu einem Bruch oder einer Beschädigung der Verbindung zwischen Metallscheibe und Zentralstange kommt, kann reduziert werden bzw. ein entsprechender Bruch effektiv verhindert werden.According to the invention the pallet shaft is characterized in that at the one end of the central rod, a metal disc which is fixed to the central rod, is incorporated in the plastic extrusion. The metal disc can be used to increase the mechanical strength of a possibly attached to this end teeth. By incorporating the metal disk in the plastic extrusion, the attachment of the metal disk is supported on the central rod beyond and the probability that it will break or damage the connection between the metal disc and the central rod can be reduced or a corresponding breakage can be effectively prevented ,
Weiterhin ist an demselben Ende eine Stirnverzahnung vorgesehen und/oder die Metallscheibe besteht teilweise oder vollständig aus ferromagnetischem Material. Die Stirnverzahnung in Verbindung mit der zumindest teilweise magnetisierbaren Metallscheibe stellt eine lösbare Verbindung der Palettenwelle zur Palettensteuerung dar.Furthermore, a spur toothing is provided at the same end and / or the metal disc consists partially or completely of ferromagnetic material. The spur toothing in conjunction with the at least partially magnetizable metal disc is a detachable connection of the pallet shaft for pallet control.
Die Stirnverzahnung und die Metallscheibe stellen eine selbstzentrierende und spielfreie Verbindung der Welle mit der Steuerung dar. Das wird erreicht durch die Metallscheibe, die mit einem entsprechenden Gegenstück in der Palettensteuerung eine axiale Haltekraft ausprägen kann. Durch die Anordnung der Stirnverzahnung wird dann eine entsprechende Verbindung hergestellt. Dadurch kann der Verschleiß, der beispielsweise durch Ausschlagen entstehen kann, vermieden werden.The spur gear and the metal disc represent a self-centering and backlash-free connection of the shaft with the controller. This is achieved by the metal disc, which can express an axial holding force with a corresponding counterpart in the pallet control. The arrangement of the spur gear teeth, a corresponding connection is then made. As a result, the wear, which can occur, for example, by knocking, can be avoided.
Weiterhin ist die Palettenwelle dadurch gekennzeichnet, dass die Kunststoffumspritzung der Palettenwelle eine Auslassung am anderen Ende der Welle aufweist.Furthermore, the pallet shaft is characterized in that the plastic extrusion of the pallet shaft has an omission at the other end of the shaft.
Diese Auslassung bzw. Freilegung kann als Gleitlagersitz dienen, mit dem die Palettenwelle in eingebautem Zustand in einem Gegenlager fixiert sein kann.This omission or exposure can serve as a sliding bearing seat, with which the pallet shaft can be fixed in the installed state in an abutment.
In einer weiteren Ausführungsform der Palettenwelle ist die Zentralstange als Hohlwelle ausgebildet. Das ermöglicht gegenüber der Verwendung von Vollwellen, beispielsweise aus Stahl oder anderem Material, bei gleichem Umfang, eine erhebliche Gewichtsersparnis, wobei die eventuell auftretenden Stabilitätseinbußen der Gesamtkonstruktion durch die Kunststoffumspritzung teilweise kompensiert werden.In a further embodiment of the pallet shaft, the central rod is designed as a hollow shaft. This allows compared to the use of solid shafts, for example made of steel or other material, with the same extent, a significant weight savings, the possibly occurring stability losses of the overall construction are partially compensated by the plastic encapsulation.
In einer weiteren Ausführungsform wird als Material für die Zentralstange Stahl oder Aluminium oder Karbon verwendet. Die Verwendung von Stahl bietet dabei eine hohe Materialfestigkeit und Widerstandsfähigkeit. Aluminium und Karbon sind demgegenüber wesentlich leichter, allerdings erfordert insbesondere Aluminium bei gleicher Biegesteifigkeit einen größeren Umfang der Palettenwelle.In another embodiment, the material used for the central rod is steel or aluminum or carbon. The use of steel offers a high material strength and resistance. In contrast, aluminum and carbon are much lighter, but aluminum in particular requires a larger circumference of the pallet shaft with the same flexural rigidity.
In einer Ausführungsform besteht die Kunststoffumspritzung der Palettenwelle aus faserverstärktem Kunststoff. Diese Form von Kunststoff ist besonders geeignet, um die Materialeigenschaften der Palettenwelle, insbesondere die Biegesteifigkeit und die Verbindung der unterschiedlichen Bauteile zu verbessern.In one embodiment, the plastic extrusion coating of the pallet shaft consists of fiber-reinforced plastic. This form of plastic is particularly suitable to improve the material properties of the pallet shaft, in particular the flexural rigidity and the connection of the different components.
In einer weiteren Ausführungsform ist die Palettenwelle dadurch gekennzeichnet, dass der Querschnitt der Palettenwelle wenigstens im Bereich der Auslassung eine nicht-runde Geometrie aufweist. Da die Palettenwelle mit der Palette gerade im Bereich der Auslassung verbunden wird, kann eine nicht-runde Geometrie der Palettenwelle in mindestens diesem Abschnitt zur Herstellung einer stellungsgerechten und formschlüssigen Verbindung zur Palette ohne Verwendung von zusätzlichen Bauteilen beitragen.In a further embodiment, the pallet shaft is characterized in that the cross section of the pallet shaft has a non-circular geometry at least in the region of the omission. Since the pallet shaft is connected to the pallet just in the area of the omission, a non-circular geometry of the pallet shaft in at least this section can contribute to the production of a positional and positive connection to the pallet without the use of additional components.
In einer Ausführungsform weist die Materialdicke der Kunststoffumspritzung über den gesamten umspritzten Bereich eine Schwankung von weniger als 5 mm, vorzugsweise 2 mm, vorzugsweise weniger als 1 mm auf. Die damit einhergehende, möglichst positionsunabhängige Materialdicke der Kunststoffumspritzung kann gerade bei hohen Drehzahlen zusätzliche Drehmomente verhindern und ermöglicht geringe Schwankungen in der Qualität jeder Palettenwelle sowie einzelnen Bereiche einer jeden Palettenwelle.In one embodiment, the material thickness of the plastic extrusion over the entire overmoulded region has a fluctuation of less than 5 mm, preferably 2 mm, preferably less than 1 mm. The concomitant, as independent of position as possible material thickness of the plastic extrusion can prevent additional torques, especially at high speeds and allows small fluctuations in the quality of each pallet shaft and individual areas of each pallet shaft.
In einer Ausführungsform der Palettenwelle ist die Stirnverzahnung eine Hirth-Verzahnung. Die Verwendung einer Hirth-Verzahnung erlaubt eine möglichst kompakte Ausführung der Verbindung mit der Palettensteuerung.In one embodiment of the pallet shaft, the front toothing is a Hirth toothing. The use of a Hirth toothing allows the most compact possible connection to the pallet control.
In einer weiteren Ausführungsform ist die Palettenwelle dadurch gekennzeichnet, dass die Verzahnung in gleichmäßiger Teilung ausgeführt ist. Dadurch kein ein umfänglich möglichst konstanter Kraftübertrag realisiert werden und somit Ausschlagen oder unerwünschte Drehmomente verhindert werden.In a further embodiment, the pallet shaft is characterized in that the toothing is designed with a uniform pitch. Thereby no one as extensively as possible Force transfer can be realized and thus knocking out or unwanted torques can be prevented.
In einer Ausführungsform ist die Palettenwelle dadurch gekennzeichnet, dass im Bereich der Verbindung der Palettenwelle mit der Steuerung eine Freilegung zum Einbringen eines Indexstifts vorgesehen ist. Dadurch kann eine stellungsgerechte Positionierung gewährleistet werden. So wird erreicht, dass die Palettenwelle nur in exakt einer Position in die Steuerung eingepasst werden kann.In one embodiment, the pallet shaft is characterized in that in the region of the connection of the pallet shaft with the control, an exposure for insertion of an index pin is provided. As a result, position-correct positioning can be ensured. This ensures that the pallet shaft can only be fitted in exactly one position in the control.
