Description

Die Erfindung betrifft eine Halteplatte für einen Staubsaugerbeutel, die eine Einlassöffnung aufweist, wobei die Halteplatte durch Thermoformen und anschließendes Stanzen einer Folie aus einem thermoplastischen Material gebildet ist.The invention relates to a holding plate for a vacuum cleaner bag having an inlet opening, wherein the holding plate is formed by thermoforming and then punching a film of a thermoplastic material.

Halteplatten für Staubsaugerfilterbeutel sind im Stand der Technik bekannt und werden aus Pappe oder Kunststoff hergestellt.Holding plates for vacuum cleaner filter bags are known in the art and are made of cardboard or plastic.

Papphalteplatten werden aus Pappbogen ausgestanzt. Gegebenenfalls werden Gummidichtungen aufgeklebt. Dickere und festere Papphalteplatten entstehen durch Aufeinanderlegen oder Aufeinanderfalten und verkleben mehrerer Lagen Pappe. Ein Dichtgummi kann dabei auch zwischen zwei Papplagen fixiert sein. Gebräuchlich ist auch die Ausstattung mit einem manuellen oder automatischen Verschluss, mit dem es möglich ist, den Filterbeutel vor der Entnahme aus dem Staubsauger zu verschließen. Es sind Lösungen mit Schiebern, z.B. EP 1 284 629 B1 , und Klappen, z.B. DE 296 15 163 U1 , bekannt. Halteplatten aus Pappe lassen sich auch in kleinen Serien kostengünstig produzieren, da die Werkzeugkosten für die Stanzwerkzeuge gering sind. Ein grundsätzliches Problem ist aber die Befestigung der Papphalteplatte auf dem Filterbeutel, insbesondere auf Filterbeuteln aus Vliesstoffen. Eine Verklebung mit dem Filterbeutel führt nicht zu den gewünschten hohen Abreißkräften, da die Pappe dazu neigt zu delaminieren und die Klebeverbindung somit nicht stärker sein kann als die Kraft, die zum Delaminieren führt. Die DE 102 03 434 A1 beschreibt eine Verschweißung einer Papphalteplatte mit einem Filterbeutel aus Vliesstoff, wenn die Papphalteplatte aufwendig mit Kunststoff beschichtet wird.Cardboard panels are punched out of cardboard sheets. If necessary, rubber seals are glued on. Thicker and stronger paperboard plates are created by stacking or folding on one another and bonding several layers of cardboard. A rubber seal can also be fixed between two cardboard layers. Also common is the equipment with a manual or automatic closure, with which it is possible to close the filter bag before removal from the vacuum cleaner. There are solutions with sliders, eg EP 1 284 629 B1 , and flaps, eg DE 296 15 163 U1 , known. Cardboard holding plates can be produced inexpensively even in small batches since the tooling costs for the punching tools are low. A fundamental problem, however, is the attachment of the cardboard board on the filter bag, especially on filter bags made of nonwovens. Bonding with the filter bag will not result in the desired high pull-off forces as the paperboard tends to delaminate and thus the adhesive bond may not be stronger than the force that results in delamination. The DE 102 03 434 A1 describes a welding of a paperboard plate with a filter bag made of nonwoven fabric, when the papal plate is consuming coated with plastic.

Kunststoffhalteplatten werden im Spritzgussverfahren hergestellt, wie in der DE 201 01 471 beschrieben. Dieses erlaubt komplexe Formen und die Integration von Dichtungen durch 2K-Spritzgussverfahren. Die P 21 16579.7-15 und die G 86 22 890.0 offenbaren einstückige Kunststoffhalteplatten mit angeformten Dichtlippen. Die Verbindung zu den heute gebräuchlichen Vliesfilterbeuteln erfolgt meist durch Ultraschallschweißverfahren. Auch gebräuchlich ist die Verklebung mit dem Filterbeutel mittels Schmelzkleber. Neben den angespritzten Elastomerdichtungen sind auch Dichtelemente gebräuchlich bei denen das Filterbeutelmaterial als Dichtelement fungiert oder bei dem eine Folie oder eine Dichtmembran auf die Halteplatte aufgeklebt oder zwischen Halteplatte und Filterbeutel positioniert ist oder sich im Inneren des Filterbeutels befindet. Eine Kunststoffhalteplate mit einer manuell zu betätigenden Verschlussklappe offenbart die DE 10 2007 053 151 A1 . Vollautomatisch schließende Kunststoffhalteplatten offenbaren die DE 10 2008 046 200 Al sowie die DE 20 2008 018 055 U1 .Plastic holding plates are produced by injection molding, as in the DE 201 01 471 described.

Wie vorstehend gezeigt, besitzen somit die eigentlich mit geringen Kosten herzustellenden Halteplatten aus Pappe den Nachteil, dass diese nicht mit Kunststoffvliesbeutel ohne Probleme verbunden werden können und auf der anderen Seite ist das Herstellen von Kunststoffhalteplatten im Spritzgussverfahren sehr aufwendig, weil hierzu jeweils ein entsprechendes Werkzeug, das sehr kostenintensiv ist, hergestellt werden muss.Thus, as shown above, the cardboard holding plates which are actually to be produced at low cost have the disadvantage that they can not be connected to plastic nonwoven bags without problems and, on the other hand, the production of plastic holding plates by injection molding is very complicated, because in each case a corresponding tool, which is very expensive, must be produced.

Ausgehend hiervon ist es deshalb die Aufgabe der vorliegenden Erfindung eine Halteplatte vorzuschlagen, die einerseits kostengünstig mit einfachen Werkzeugen herstellbar ist und die anderseits auch problemlos mit Filterbeuteln aus Vliesstoffmaterial verbunden werden kann.Based on this, it is therefore the object of the present invention to propose a holding plate, on the one hand inexpensive to produce with simple tools and on the other hand can be easily connected to filter bags made of nonwoven material.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Die Unteransprüche zeigen vorteilhafte Weiterbildungen auf.This object is solved by the features of claim 1. The dependent claims show advantageous developments.

Erfindungsgemäß wird somit eine Halteplatte für einen Staubsaugerbeutel, der bevorzugt aus einem Vliesmaterial gebildet ist, vorgeschlagen, die durch thermoformen und anschließendes Stanzen einer Folie aus einem thermoplastischen Material gebildet ist.According to the invention, a holding plate for a vacuum cleaner bag, which is preferably formed from a nonwoven material, is proposed, which is formed by thermoforming and then punching a film of a thermoplastic material.

Dadurch, dass erfindungsgemäß die Halteplatte durch Thermoformen (Tiefziehen) und Stanzen hergestellt wird, stehen kostengünstige Halteplatten aus einem thermoplastischen Material zur Verfügung, die sich problemlos mit dem thermoplastischen Vliesmaterial eines Staubsaugerfilterbeutels verbinden lassen. Der Herstellungsprozess des Thermoformens (Tiefziehen) ist schnell und kostengünstig. Die Werkzeugkosten sind niedrig und erlauben somit auch ein günstigeres Herstellen von Kleinserien. Das Thermoformen ist ein Verfahren zur Umformung thermoplastischer Kunststoffe. Gemäß der Erfindung wird das Thermoformen mit einer Folie durchgeführt. Der Prozess des Thermoformen und die hierzu erforderlichen Werkzeuge sind dem Fachmann bekannt. Gebräuchliche Verfahren sind hierbei das sog. Vakuumformen und das Druckluftformen. Der Vorteil des Vakuumformen besteht darin, dass sowohl die Maschinen als auch die Werkzeuge preiswert sind. Beim Vakuumformen kann dabei eine sog. Negativverformung durchgeführt werden, bei der meist ein Stempel eingesetzt wird. Die Positivverformung, die ebenfalls möglich ist, wird meist nur für flache oder reliefartige Teile eingesetzt. Grundsätzlich ist auch ein Druckluftformen möglich. Das Vakuumformen ist aber gemäß der vorliegenden Erfindung begünstigt, da die Maschinen für das Druckluftformen teuer sind und für die Werkzeuge ein hoher Aufwand erforderlich ist.Due to the fact that, according to the invention, the holding plate is produced by thermoforming (deep-drawing) and stamping, cost-effective holding plates made of a thermoplastic material are available which can be easily connected to the thermoplastic nonwoven material a vacuum cleaner filter bag connect. The manufacturing process of thermoforming (deep drawing) is fast and inexpensive. The tooling costs are low and thus allow a cheaper production of small batches. Thermoforming is a process for forming thermoplastics. According to the invention, the thermoforming is carried out with a film. The process of thermoforming and the tools required for this purpose are known in the art. Common methods here are the so-called. Vacuum forming and compressed air forming. The advantage of vacuum forming is that both the machines and the tools are inexpensive. When vacuum forming, a so-called. Negative deformation can be carried out, in which usually a punch is used. The positive deformation, which is also possible, is usually used only for flat or relief-like parts. Basically, a compressed air forming is possible. However, the vacuum forming is favored according to the present invention, since the machines for the compressed air forming are expensive and for the tools a lot of effort is required.

Ein weiterer Vorteil der erfindungsgemäßen Halteplatte, die nach einem wie vorstehend beschriebenen Thermoformen erhalten wird, besteht darin, dass das thermoplastische Material der Halteplatte frei gewählt werden kann, so dass auch ein problemloses Verbinden beispielsweise durch Ultraschallschweißen, mit dem thermoplastischen Material eines Vliesstofffilterbeutel möglich ist. Hervorzuheben ist, dass der Materialeinsatz gering ist und die erforderliche Stabilität über die Foliendicke und z. B. eingebrachte Versteifungsrippen gesteuert werden kann. Weiterhin zeichnet sich die neue Halteplatte dadurch aus, dass die Folien, die für das Thermoformen eingesetzt werden, üblicherweise eine starke Anisotropie aufweisen, so dass sich diese gezielt dahingehend ausgenützt werden kann, dass die Biegesteifrichtung sich in die Richtung der Halteplatte erstreckt, die nicht durch Rippen oder Sicken verstärkt sein kann oder die stärker belastet wird. Ein entscheidender Vorteil der Halteplatte nach der Erfindung besteht somit darin, dass die Halteplatten sich nicht nur einfach und kostengünstig herstellen lassen, sondern dass die Eigenschaften gezielt eingestellt werden können unter Ausnutzung der Anisotropie der Folien und dem Einbringen von Rippen bzw. Sicken. Weiter hervorzuheben ist, dass die Halteplatte nach der Erfindung auch aus mehrschichtigen Folien aufgebaut sein können und wobei dann sich die Folien in der Auswahl des thermoplastischen Materials unterscheiden können, so dass die nach außengerichtete Seite aus einem anderen thermoplastischen Material bestehen kann, wie diejenige Seite, die mit dem Vliesstoffmaterial verbunden ist.Another advantage of the holding plate according to the invention, which is obtained after a thermoforming as described above, is that the thermoplastic material of the holding plate can be chosen freely, so that a trouble-free connection, for example by ultrasonic welding, with the thermoplastic material of a nonwoven filter bag is possible. It should be emphasized that the material usage is low and the required stability over the film thickness and z. B. introduced stiffening ribs can be controlled. Furthermore, the new holding plate is characterized in that the films that are used for thermoforming, Usually have a strong anisotropy, so that it can be exploited specifically to the effect that the bending direction extends in the direction of the holding plate, which can not be reinforced by ribs or beads or more heavily loaded. A decisive advantage of the retaining plate according to the invention is thus that the retaining plates can not only be produced easily and inexpensively, but that the properties can be adjusted specifically by taking advantage of the anisotropy of the films and the introduction of ribs or beads. It should also be emphasized that the holding plate according to the invention can also be constructed of multilayer films and in which case the films may differ in the selection of the thermoplastic material, so that the outwardly directed side may consist of another thermoplastic material, such as the one side, which is connected to the nonwoven material.

Neben durchsichtigen oder gefärbten Folien sind auch geschäumte Folien einsetzbar. Dadurch lässt sich dem Materialeinsatz noch weiter reduzieren. Faserverstärkte Folien, die ebenfalls beim Thermoformen verwendet werden können und die bei der Erfindung bevorzugt sind, weisen hinsichtlich der mechanischen Belastbarkeit eine noch höhere Anisotropie auf als unverstärkte Folien. Auch damit lässt sich der Materialeinsatz weiter reduzieren bzw. die die Festigkeit der Platten verbessern. Die Folien lassen sich ebenfalls beim Umformen mit Filmscharnieren versehen.In addition to transparent or colored films and foamed films can be used. As a result, the use of materials can be further reduced. Fiber-reinforced films, which can also be used in thermoforming and which are preferred in the invention, have an even higher anisotropy in terms of mechanical strength than unreinforced films. Even with this, the use of materials can be further reduced or improve the strength of the plates. The films can also be provided with film hinges during forming.

Die erfindungsgemäße Halteplatte ist dabei bevorzugt als einstückiges Bauteil ausgebildet. Der Thermoformprozess, der für die erfindungsgemäße Halteplatte eingesetzt wird, erlaubt es zudem, dass die Halteplatte und die Klappe gemeinsam als einstückiges Bauteil ausgebildet ist, wobei auch in einer bevorzugten Ausführungsform noch vorgesehen sein kann, dass die Klappe über ein Scharnier mit der Halteplatte einstückig verbunden ist.The holding plate according to the invention is preferably designed as a one-piece component. The thermoforming process, for the holding plate according to the invention is used, it also allows that the holding plate and the flap is formed together as a one-piece component, wherein even in a preferred embodiment can still be provided that the flap is integrally connected via a hinge to the holding plate.

Von der stofflichen Seite her ist es bevorzugt, wenn das thermoplastische Material der Folie aus Polyprophylen (PP), Polyethylen (PE), Polyvinylchlorid (PVC), Polycarbonat (PC) und/oder Polyethylenterephthelat (PET) ausgewählt ist. Die vorstehend genannte Auswahl betrifft nur bevorzugte Ausführungsformen. Allgemein können die Halteplatten aus allen dem Fachmann bekannten thermoplastischen Materialien bestehen.From the material side, it is preferred that the thermoplastic material of the film of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polycarbonate (PC) and / or polyethylene terephthalate (PET) is selected. The above selection relates only to preferred embodiments. In general, the holding plates may consist of all known to the expert thermoplastic materials.

Die Folie, die beim Thermoformen verwendet wird, kann dabei auch eine mehrschichtige Folie mit einer Dicke im Bereich von 0,2 bis 2,5 mm, bevorzugt mit einer Dicke von 0,5 bis 1,5 mm sein. Selbstverständlich umfasst die Erfindung auch Ausführungsformen, bei denen nur eine einzige Folie in dem vorstehend genannten Dickenbereich verwendet wird. Bevorzugt ist es dabei, wenn bei mehrschichtigen Folien diese aus zwei bis zwanzig Schichten gebildet ist. Derartige mehrschichtige Folien, d.h. Laminate, die dann im Thermoformprozess zugeführt werden, sind ebenfalls im Stand der Technik bekannt und handelsüblich. Bei der erfindungsgemäßen Halteplatte kann dadurch, dass beim Thermoformprozess auch mehrschichtige Folien eingesetzt werden können, diese so ausgebildet sein, dass z.B. diejenige Schicht, der Laminatfolie, die in Richtung des Vliesstoffbeutels orientiert wird, aus einem thermoplastischen Material mit einem niedrigeren Schmelzpunkt besteht, als die außenseitigeThe film used in thermoforming can also be a multilayer film having a thickness in the range of 0.2 to 2.5 mm, preferably in a thickness of 0.5 to 1.5 mm. Of course, the invention also includes embodiments in which only a single film in the thickness range mentioned above is used. In the case of multilayer films, this is preferably formed from two to twenty layers. Such multilayer films, ie laminates, which are then fed in the thermoforming process are also known in the art and commercially available. In the case of the holding plate according to the invention, as a result of the fact that multilayer films can also be used in the thermoforming process, they can be designed so that, for example, that layer, the laminate film which is oriented in the direction of the nonwoven fabric bag, consists of a thermoplastic material having a lower melting point than the one outside

Ebenso können gezielt Farbeffekte und/oder Rippen und Verstärkungen in die Folien eingebracht werden.Layer. As a result, a light welding is possible. The use of multilayer laminate films also allows for the possibility of one or more of the films being reinforced. Likewise, color effects and / or ribs and reinforcements can be deliberately introduced into the films.

Die Erfindung wird nachstehend anhand zweier Figuren näher erläutert.The invention will be explained in more detail below with reference to two figures.

Figur 1 zeigt eine Draufsicht einer erfindungsgemäßen Halteplatte und Figur 2 schematisch den Ablauf des Prozesses beim Thermoformen. FIG. 1 shows a plan view of a holding plate according to the invention and FIG. 2 schematically the process of thermoforming.

Die in Figur 1 dargestellte Halteplatte 1 weist eine Einlassöffnung 2 auf, die mit einer Klappe 3 verschließbar ist. Die in Figur 1 gezeigte Ausführungsform ist als einstückiges Bauteil ausgebildet, d.h. die Halteplatte 1 wurde durch Thermoformen und Stanzen aus einer Folie gebildet. Die Halteplatte 1, wie sie in Figur 1 beschrieben ist, weist weiterhin Verstärkungsrippen 4 auf. Die Verstärkungsrippen 4 können verschiedenartig ausgebildet sein. Bevorzugt sind sie wie die Verstärkungsrippe 4 in Pfeilform in einer hoch-tief Struktur ausgebildet. Die Verstärkungsrippe 4 kann auch durch Verstärkungsfasern die in der Folie vorhanden sind ersetzt sein oder in Kombination mit den Verstärkungsrippen vorhanden sein. Die Klappe 3 ist dabei über ein Scharnier 5 einstückig mit der Halteplatte 1 verbunden. Dadurch, dass sich die Klappe 3 mit der Halteplatte 1 über ein Filmscharnier 5 verbinden lässt, ist eine kostengünstige Produktion von Halteplatten möglich, denn die Klappe 3 muss nicht in einem separaten Arbeitsgang mit dem restlichen Bauteil der Halteplatte 1 verbunden werden, sondern lässt sich einstückig ausbilden. Als Material für die Halteplatte 1, wie sie in Figur 1 dargestellt ist, lassen sich beliebige Materialen, die thermoplastisch verformbar sind, einsetzen. Die Auswahl des thermoplastischen Materials richtet sich dabei nach dem Einsatzzweck. So kann es vorteilhaft sein, die Halteplatte 1 aus zwei übereinander angeordneten Schichten aus unterschiedlichen Kunststoffen zu bilden. Für diesen Fall ist die dem Filterbeutel zugewandte Lage aus einem thermoplastischen Material mit einem niedrigeren Schmelzpunkt, als die dem Filterbeutel abgewandte Seite gebildet, so dass der Schweißprozess zum Verbinden der Halteplatte 1 mit dem Filterbeutel schnell und energiesparend erfolgen kann.In the FIG. 1 shown retaining plate 1 has an inlet opening 2, which is closable with a flap 3. In the FIG. 1 embodiment shown is formed as a one-piece component, ie, the holding plate 1 was formed by thermoforming and punching of a film. The holding plate 1, as in FIG. 1 is described, further comprises reinforcing ribs 4. The reinforcing ribs 4 may be formed in various ways. Preferably, they are like the reinforcing rib 4 in arrow shape formed in a high-deep structure. The reinforcing rib 4 may also be replaced by reinforcing fibers present in the foil or in combination with the reinforcing ribs. The flap 3 is connected via a hinge 5 integral with the retaining plate 1. The fact that the flap 3 can be connected to the holding plate 1 via a film hinge 5, a cost-effective production of holding plates is possible because the flap 3 does not have to be connected in a separate operation with the rest of the mounting plate 1, but can be made in one piece form. As a material for the holding plate 1, as in FIG. 1 is shown, any materials that are thermoplastically deformable, can be used. The selection of the thermoplastic material depends on the purpose. Thus, it may be advantageous to form the holding plate 1 of two superposed layers of different plastics. In this case, the layer facing the filter bag is formed from a thermoplastic material with a lower melting point than the side facing away from the filter bag, so that the welding process for connecting the holding plate 1 to the filter bag can be done quickly and energy-saving.

In Figur 2 ist in schematischer Darstellung einer aus dem Stand der Technik bekannte Anlage zum Thermoformen mit Rollenmaterial gezeigt. Wie aus Figur 2 hervorgeht, wird von einer Rolle 10 das Folienmaterial in eine Aufwärmstation 11, die Heizstrahler 12 aufweist, geführt. In der Aufwärmstation 11 können dabei Heizstrahler 12 ein oder beidseitig vorhanden sein. In der Werkzeugstation 13 wird die Folie dann mittels Spannrahmen festgehalten, Vorstrecker und das Thermoformwerkzeug fahren durch die Folienebene durch und geben die fertige Kontur schon grob vor. Nachfolgend wird dann Druckluft von der einen und Vakuum von der anderen Seite erzeugt, um die Folie rasch und stark an die gekühlte Wandung (Kontur) des Formwerkzeuges 15 zu bringen. Die erkaltete und nun feste Folie wird von dem Formwerkzeug 15 getrennt und im nächsten Arbeitsschritt der Ausstanzstation 14 zugeführt.In FIG. 2 is shown in a schematic representation of a known from the prior art system for thermoforming with roll material. How out FIG. 2 is apparent from a roll 10, the film material in a warm-up station 11, the radiant heater 12, out. In the warm-up station 11, radiant heaters 12 can be present on one or both sides. In the tool station 13, the film is then held by means of clamping frames, pre-stretchers and the thermoforming tool pass through the film plane and give the finished contour before roughly. Subsequently, compressed air is then generated by one and vacuum from the other side to bring the film quickly and strongly to the cooled wall (contour) of the mold 15. The cooled and now solid film is separated from the mold 15 and fed to the punching station 14 in the next step.

Der wie vorstehend bei Figur 2 beschriebene Arbeitsablauf wird auch für die in Figur 1 dargestellte Halteplatte angewendet.The as in the above FIG. 2 described workflow is also for the in FIG. 1 shown holding plate applied.
