Description

Die Erfindung bezieht sich auf eine Reinigungsscheibe nach dem Oberbegriff des Patentanspruchs 1 sowie auf ein Verfahren zur Herstellung der Reinigungsscheibe nach dem Oberbegriff des Patentanspruchs 5.The invention relates to a cleaning disc according to the preamble of patent claim 1 and to a method for producing the cleaning disc according to the preamble of patent claim 5.

Aus der DE 20 2015 002 688 U1 kann ein maschinell angetriebenes Reinigungsgerät und eine Reinigungsscheibe entnommen werden, die mittels des Reinigungsgerätes während des Betriebszustandes in Rotation versetzt und in Richtung eines zu reinigenden Untergrundes abgesenkt ist. Die Reinigungsscheibe besteht vollständig aus einem Melaminharz-Schaum-Material, durch das eine Reinigungsschicht gebildet ist. Darüber hinaus weist die Reinigungsscheibe eine weitere Schicht auf, um deren Form zu stabilisieren. Während des Reinigungsvorganges ist die Reinigungsschicht aus Melaminharz-Schaum dem Untergrund zugewandt. Aufgrund der von dem Reinigungsgerät ausgeübten Rotation und entsprechend eingesetzten chemischen Reinigungsmitteln können unterschiedlich ausgestaltete Untergründe gesäubert werden. Durch die Rotationsbewegungen der Reinigungsscheibe entsteht eine Reibkraft zwischen dieser und dem Untergrund, wodurch die Reinigungsscheibe im Verlauf ihres Betriebes abgenutzt ist. Folglich verringert sich währenddessen die Dicke der Reinigungsscheibe bis diese vollständig aufgebraucht ist.From the DE 20 2015 002 688 U1 a mechanically driven cleaning device and a cleaning disc can be removed, which is set in rotation by means of the cleaning device during the operating state and is lowered in the direction of a substrate to be cleaned. The cleaning disk consists entirely of a melamine resin foam material, through which a cleaning layer is formed. In addition, the cleaning disc has another layer to stabilize its shape. During the cleaning process, the cleaning layer made of melamine resin foam faces the surface. Due to the rotation exerted by the cleaning device and the corresponding use of chemical cleaning agents, different surfaces can be cleaned. The rotational movements of the cleaning disk create a frictional force between the latter and the substrate, as a result of which the cleaning disk is worn out in the course of its operation. As a result, the thickness of the cleaning disk decreases in the meantime until it is completely used up.

Da das Reinigungsgerät über eine höhenverstellbare Antriebsvorrichtung verfügt, die mit der Reinigungsscheibe trieblich gekoppelt ist, kann der Dickenverlust der Reinigungsscheibe permanent ausgeglichen sein. Gleichwohl ist die Reinigungsscheibe ab einer gewissen Dicke auszutauschen und durch eine neue Reinigungsscheibe zu ersetzen.Since the cleaning device has a height-adjustable drive device which is drivingly coupled to the cleaning disc, the loss in thickness of the cleaning disc can be permanently compensated. Nevertheless, the cleaning disc to be replaced from a certain thickness and replaced with a new cleaning disc.

Solche Reinigungsscheiben aus einem Melaminharz-Schaum weisen eine extrem hochwertige Reinigungskraft für harte Untergründe, beispielsweise Fliesen, Feinsteinzeug, Naturstein, Parkett oder Kunststoffbeläge auf. Folglich können mittels der Reinigungsscheibe Reinigungsgeräte verwendet werden, die über eine geringe Antriebskraft bzw. Drehmoment für die Rotation der Reinigungsscheibe verfügen, ohne dass der gewünschte Reinigungseffekt beeinträchtigt ist. Nachteiliger Weise können die Reinigungsscheibe aus einem Textilmaterial oder sonstigen anderen Werkstoffen die Reinigungswirkung einer Reinigungsscheibe aus Melaminharz-Schaum nicht erreichen. Die Reinigungsscheiben aus einem anderen Werkstoff als Melaminharz-Schaum sind jedoch in ihrer Herstellung wesentlich kostengünstiger und für Reinigungsgeräte mit einer geringen Antriebsleistung zu verwenden. Da die Reibkräfte von Reinigungsscheiben aus einem Melaminharz-Schaum wesentlich höher sind als bei textilen Reinigungsscheiben, treten oftmals Störungen an den Reinigungsgeräten wegen diesen Überlastungen auf. Dies behindert den Arbeitsablauf erheblich, da solche Stillstandszeiten ungeplant erfolgen und langwierig sind.Such cleaning disks made of a melamine resin foam have an extremely high-quality cleaning power for hard surfaces, for example tiles, fine stoneware, natural stone, parquet or plastic coverings. Consequently, by means of the cleaning disk, cleaning devices can be used which have a low driving force or torque for rotating the cleaning disk, without the desired cleaning effect being impaired. Disadvantageously, the cleaning disk made of a textile material or other other materials cannot achieve the cleaning effect of a cleaning disk made of melamine resin foam. However, the cleaning discs made of a material other than melamine resin foam are significantly cheaper to produce and can be used for cleaning devices with a low drive power. Since the frictional forces of cleaning disks made of melamine resin foam are significantly higher than with textile cleaning disks, the cleaning devices often malfunction due to this overload. This significantly impedes the workflow, since such downtimes are unplanned and lengthy.

Aufgrund der Werkstoffeigenschaften des verwendeten Melaminharz-Schaum entstehen oftmals erhöhte Reibungskräfte zwischen dieser und einem Untergrund. Wenn der Untergrund jedoch aus einem empfindlichen Material gefertigt ist, können diese Melaminharz-Schaum-Reinigungsscheiben Beschädigungen an der Oberfläche des Untergrundes hervorrufen. Zudem sind die Standzeiten solcher Reinigungsscheiben aus Melaminharz-Schaum im Vergleich mit herkömmlichen Reinigungsscheiben aus einem textilen oder sonstigen Werkstoff geringer.Due to the material properties of the melamine resin foam used, increased frictional forces often arise between this and a substrate. However, if the floor is made of a sensitive material, these melamine resin foam cleaning disks can cause damage to the surface of the floor. In addition, the service life of such cleaning disks made of melamine resin foam is shorter in comparison with conventional cleaning disks made of a textile or other material.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Reinigungsscheibe der eingangs genannten Gattung derart weiterzubilden, dass die vorgenannten Nachteile ausgeräumt sind, dass also die Standzeiten der Reinigungsscheibe erhöht sind, ohne dass deren Reinigungswirkung beeinträchtigt ist. Gleichzeitig soll die Reibkraft, die zwischen der Reinigungsscheibe und einem zu säubernden Untergrund vorhanden ist, durch die Materialeigenschaften der erfindungsgemäßen Reinigungsscheibe exakt vorgegeben bzw. vorbestimmt sein, sodass Beschädigungen auf der Oberfläche eines zu reinigenden Untergrundes durch einen unsachgemäßen Gebrauch des Reinigungsgerätes mit einer solchen Reinigungsscheibe vermieden sind. Zudem soll die reduzierte Reibkraft unter Beibehaltung der Reinigungswirkung der Einsatz von Reinigungsgeräten mit einer geringen Antriebskraft gestalten.The invention is therefore based on the object of further developing a cleaning disc of the type mentioned at the outset in such a way that the aforementioned disadvantages are eliminated, ie the service life of the cleaning disc is increased without its cleaning effect being impaired. At the same time, the frictional force that is present between the cleaning disk and a substrate to be cleaned should be precisely specified or predetermined by the material properties of the cleaning disk according to the invention, so that damage to the surface occurs of a substrate to be cleaned are avoided by improper use of the cleaning device with such a cleaning disk. In addition, the reduced frictional force while maintaining the cleaning effect should allow the use of cleaning devices with a low driving force.

Diese Aufgaben werden erfindungsgemäß durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 für den Aufbau der Reinigungsscheibe und durch die Merkmale des Verfahrensanspruches 5 für die Herstellung der Reinigungsscheibe gelöst.These objects are achieved according to the invention by the features of the characterizing part of patent claim 1 for the structure of the cleaning disc and by the features of method claim 5 for the production of the cleaning disc.

Weitere vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Further advantageous developments result from the dependent claims.

Dadurch, dass zwischen den Melaminharz-Schaum-Partikeln mehrere vereinzelte Stücke eingebracht sind, die aus einem textilen oder künstlichen Material, vorzugsweise aus einem Polyester-non-woven-Material, bestehen, entsteht eine Reinigungsscheibe mit einem gleichbleibenden hochwertigen Reinigungseffekt und durch die Zumischung von Stücken aus Polyester-non-woven-Material verringert sich in Abhängigkeit von dem Verhältnis zwischen Melaminharz-Schaum-Partikeln und den zu gemischten Polyester-non-woven-Stücken eine einstellbare Reibkraft. Demnach kann bereits mit der Auswahl einer entsprechenden Reinigungsscheibe die unterschiedlichen Oberflächeneigenschaften von zu reinigenden Untergründen und die Antriebsleistung der vorhandenen Reinigungsgeräte berücksichtigt werden, um diese vor Beschädigungen durch eine unsachgemäße Benutzung des Reinigungsgerätes bzw. mit einer Reinigungsscheibe mit hoher Reibkraft vermieden sein.The fact that several individual pieces made of a textile or artificial material, preferably a polyester non-woven material, are inserted between the melamine resin foam particles results in a cleaning disc with a consistently high-quality cleaning effect and the admixture of Pieces of polyester non-woven material decreases an adjustable frictional force depending on the ratio between melamine resin foam particles and the mixed polyester non-woven pieces. Accordingly, the different surface properties of the substrates to be cleaned and the drive power of the existing cleaning devices can already be taken into account when selecting a corresponding cleaning disc, in order to prevent them from being damaged by improper use of the cleaning device or with a cleaning disc with high frictional force.

Durch die Herstellungsschritte dieser Reinigungsscheibe können zudem die abgeschnittenen Materialien wiederverwendet werden, denn die überstehende an dem Außenumfang der aus den Druckzylinder entfernten Reinigungsscheibe bestehen aus einem identischen Werkstoff, nämlich Polyester-non-woven-Material, sodass die dort entstehenden Reste für die weitere Herstellung von neuen Reinigungsscheiben verwendet werden können.Through the manufacturing steps of this cleaning disc, the cut materials can also be reused, because the protruding parts on the outer circumference of the cleaning disc removed from the printing cylinder are made of an identical material, namely polyester non-woven material, so that the residues produced there can be used for the further production of new cleaning discs can be used.

Aufgrund der relativ lang bemessenen Austrocknungsperiode, währenddessen eine konstante Druckkraft auf die im Inneren des Druckzylinder eingeschlossenen Partikel und Stücke einwirken, entsteht ein formstabiles Gewebe oder Gebilde mit beliebigen Außenkonturen bzw. Querschnitten, bspw. rund, rechteckig, elliptisch oder dgl., dessen Dicke individuell auswählbar ist, da die jeweiligen Reinigungsscheiben vereinzelt mit unterschiedlichen Höhen abgeschnitten werden können. Die aufgrund der vorhandenen Fehlertoleranzen entstehenden Überstände an dem Außenumfang der gesamten Reinigungsscheibe könne nachfolgend mithilfe eines Messers oder eines sonstigen Werkzeugs derart abgeschnitten sein, dass eine Reinigungsscheibe mit einem vorgegebenen Durchmesser gebildet ist. Auch die Bohrung im Zentrum der Reinigungsscheibe ist individuell ausgestaltbar, sodass die derart hergestellten Reinigungsscheiben vorteilhafter Weise für eine Vielzahl von unterschiedlichen Reinigungsgeräten einsetzbar sind.Due to the relatively long drying period, during which a constant compressive force is exerted on the particles trapped inside the pressure cylinder and pieces act, a dimensionally stable fabric or structure is created with any outer contours or cross-sections, e.g. round, rectangular, elliptical or the like. The thickness of which can be selected individually, since the respective cleaning discs can be cut off individually with different heights. The overhangs on the outer circumference of the entire cleaning disc that occur due to the existing error tolerances can subsequently be cut off using a knife or another tool in such a way that a cleaning disc with a predetermined diameter is formed. The hole in the center of the cleaning disc can also be designed individually, so that the cleaning discs produced in this way can advantageously be used for a large number of different cleaning devices.

Durch die Zumischung von unterschiedlichen Volumenanteilen der Melaminharz-Schaum-Partikel und der Polyester-non-woven-Stücke in einem Mischer kann die Reinigungswirkung der Reinigungsscheibe sowie deren Reibkraft vorgegeben sein. Je höher der Anteil der Melaminharz-Schaum-Partikel im Verhältnis zu den eingemischten Polyester-non-woven-Stücken ausgestaltet ist, desto größer ist die entstehende Reibkraft und die Reinigungswirkung geht vorteilhafter Weise erst bei einer signifikanten Reduzierung der Melaminharz-Schaumpartikel auf unter 10 % des gesamten Volumenanteils zurück. Solange demnach ein genügend groß bemessener Anteil von Melaminharz-Schaum-Partikel in der Reinigungsscheibe vorhanden sind, ist eine ausreichende Reinigungswirkung erreicht.The cleaning effect of the cleaning disk and its frictional force can be predetermined by mixing in different volume fractions of the melamine resin foam particles and the polyester nonwoven pieces in a mixer. The higher the proportion of melamine resin foam particles in relation to the polyester non-woven pieces mixed in, the greater the frictional force that occurs and the cleaning effect advantageously only starts when the melamine resin foam particles are significantly reduced to below 10%. of the total volume fraction. Accordingly, as long as a sufficiently large proportion of melamine resin foam particles are present in the cleaning disk, an adequate cleaning effect is achieved.

In den Figuren 1 bis 5 sind die Verfahrensschritte zur Herstellung einer Reinigungsscheibe 1 zu entnehmen, die insbesondere für ein maschinell angetriebenes Reinigungsgerät einsetzbar ist. Die Reinigungsscheibe 1 wird durch das Reinigungsgerät im Betriebszustand um ihre Längsachse 2 rotierend angetrieben oder das Reinigungsgerät erzeugt oszillierende Schwingungen, durch die insbesondere rechteckförmige Reinigungsscheiben 1 eine Bewegung ausüben, durch die ein guter Reinigungseffekt entsteht. Solche Reinigungsgeräte sind als Oszillator-Exzentergeräte bekannt.In the Figures 1 to 5 the process steps for the production of a cleaning disc 1 can be seen, which can be used in particular for a machine-driven cleaning device. The cleaning disc 1 is driven by the cleaning device to rotate about its longitudinal axis 2 in the operating state, or the cleaning device generates oscillating vibrations, through which, in particular, rectangular cleaning discs 1 exert a movement that produces a good cleaning effect. Such cleaning devices are known as oscillator eccentric devices.

Gemäß Figur 1 besteht die Reinigungsscheibe 1 aus einer Vielzahl von Melamin-Harzschaum-Partikeln 6 und Polyester- bzw. Polyamid-non-woven-Stücken 11, die in einem Mischer 12 zu einem möglichst homogenen Gewebe 6, 11 vermengt sind. In Abhängigkeit von den gewählten Volumenanteilen der Partikel 6 und der Stücke 11 soll das in dem Mischer 12 vermengte Gewebe 6, 11 eine möglichst gleichmäßige Anordnung von Partikeln 6 und Stücken 11 aufweisen. Während des Mischvorganges in dem Mischer 12 wird ein Kleber 7 in Tropfenform gleichmäßig zugeführt, sodass sich die Oberflächen der Partikel 6 und der Stücke 11 mit den Tropfen des Kleber 7 benetzen und folglich durch die Klebeeigenschaften des Klebers 7 aneinanderhaften. Folglich entsteht in dem Mischer 12 ein Gewebe aus Melamin-Harzschaum-Partikel 6 und Polyester-non-woven-Stücken 11.According to figure 1 the cleaning disc 1 consists of a large number of melamine resin foam particles 6 and polyester or polyamide non-woven pieces 11, which are mixed in a mixer 12 to form a fabric 6, 11 that is as homogeneous as possible. Depending on the selected volume proportions of the particles 6 and the pieces 11, the tissue 6, 11 mixed in the mixer 12 should have an arrangement of particles 6 and pieces 11 which is as uniform as possible. During the mixing process in the mixer 12, an adhesive 7 is fed evenly in the form of drops, so that the surfaces of the particles 6 and the pieces 11 are wetted with the drops of the adhesive 7 and consequently adhere to one another by the adhesive properties of the adhesive 7. Consequently, a fabric made of melamine resin foam particles 6 and polyester non-woven pieces 11 is produced in the mixer 12.

Figur 2 ist zu entnehmen, dass das derart in dem Mischer 12 hergestellte Gewebe 6, 11 in einen Druckzylinder 13 überführt ist. Der Druckzylinder 13 weist eine vorgegebene Höhe oder Länge auf und ist üblicherweise rund ausgestaltet. Jede andere Querschnittsform für den Druckzylinder 13 ist möglich, bspw. rechteckig, elliptisch oder dgl. Die beiden seitlichen Stirnseiten des Druckzylinders 13 sind einerseits mittels einer Bodenplatte 17 und andererseits mittels einer Druckplatte 18 verschlossen. Sobald der Innenraum des Druckzylinders 13 vollständig mit dem Gewebe 6, 11 befüllt ist, wird die Druckplatte 18 beispielsweise durch eine Gewindespindel 19 in Richtung des Innenraums des Druckzylinders 13 zugestellt. Folglich ist das eingefüllte Gewebe 6, 11 vollständig in dem Druckzylinder 13 eingeschlossen und die Druckplatte 18 übt eine Druckkraft F auf das in dem Druckzylinder 13 vorhandene Gewebe 6, 11 aus. Dadurch, dass das Gewebe 6, 11 der Druckkraft F über einen bestimmten Zeitraum von beispielsweise 24 Stunden ausgesetzt ist, verdichtet sich das Gewebe 6, 11 und die vorhandenen Lufteinschlüsse werden ausgepresst. Bei dieser Ausgestaltung des Druckzylinders 13 handelt es sich um eine beispielhafte Ausführung; jede weitere Querschnittsform für den Druckzylinder 13 ist möglich, um die Reinigungsscheibe 1 an die vorhandenen Einsatzzwecke anzupassen. figure 2 It can be seen that the fabric 6 , 11 produced in the mixer 12 in this way is transferred to a pressure cylinder 13 . The pressure cylinder 13 has a predetermined height or length and is usually designed around. Any other cross-sectional shape for the pressure cylinder 13 is possible, e.g. rectangular, elliptical or the like. As soon as the interior of the printing cylinder 13 is completely filled with the fabric 6, 11, the printing plate 18 is advanced in the direction of the interior of the printing cylinder 13, for example by a threaded spindle 19. Consequently, the filled tissue 6, 11 is completely enclosed in the impression cylinder 13 and the pressure plate 18 exerts a compressive force F on the tissue 6, 11 present in the impression cylinder 13. Due to the fact that the tissue 6, 11 is exposed to the compressive force F over a certain period of time, for example 24 hours, the tissue 6, 11 is compressed and the air pockets that are present are pressed out. This embodiment of the pressure cylinder 13 is an exemplary embodiment; any other cross-sectional shape for the pressure cylinder 13 is possible in order to adapt the cleaning disc 1 to the existing purposes.

Sobald der Verdichtungs- und Austrocknungszeitpunkt erreicht ist, kann das Gewebe aus Partikeln 6 und Stücken 11 aus dem Druckzylinder 13 gemäß Figur 4 entnommen werden. Aufgrund der vorgegebenen Geometrie des Druckzylinders 13 entsteht eine zylinderförmige Kontur, die eine dem Druckzylinder 13 entsprechende Länge und Durchmesser aufweist. Da die Höhen der zu verwendenden Reinigungsscheibe 1 unterschiedlich sein können, können die entsprechenden vereinzelten Reinigungsscheiben 1 aus dieser zylinderförmigen Kontur mittels eines Messers abgetrennt sein.As soon as the compression and drying time has been reached, the tissue of particles 6 and pieces 11 can be removed from the pressure cylinder 13 according to FIG figure 4 be removed. Due to the predetermined geometry of the pressure cylinder 13, a cylindrical contour is created which has a length and diameter corresponding to the pressure cylinder 13. Since the heights of the cleaning disc 1 to be used can be different, the corresponding individual cleaning discs 1 can be separated from this cylindrical contour by means of a knife.

Da in dem Druckzylinder 13 die Gewindespindel 19 im Zentrum des Druckzylinders 13 angeordnet ist, entsteht im Zentrum des Gewebes 6, 11 eine Bohrung 3. Sobald das Gewebe 6, 11 zur Bildung der Reinigungsscheibe 1 vereinzelt ist, ist es erforderlich, dass das Gewebe 6, 11 mittels einer Trägerschicht 4 versteift ist. Die Trägerschicht 4 als Rückenmaterial besteht dabei aus einem Polyester-non-woven-Material oder einem Klett-Material. Der Durchmesser der Trägerschicht 4 ist an den gewünschten Durchmesser der Gewebeausbildung 6, 11 anzupassen, sodass die jeweiligen Überstände 15 mittels eines Messers 16 gemäß der rechten Seite des Figur 5 abgetrennt sind. Folglich verlaufen die Außenumfänge des Gewebes 6, 11 und der Trägerschicht 4 fluchtend zueinander.Since the threaded spindle 19 is arranged in the center of the pressure cylinder 13 in the pressure cylinder 13, a hole 3 is formed in the center of the fabric 6, 11. As soon as the fabric 6, 11 has been separated to form the cleaning disk 1, it is necessary for the fabric 6 , 11 is reinforced by means of a carrier layer 4 . The backing layer 4 as backing material consists of a polyester non-woven material or a Velcro material. The diameter of the carrier layer 4 is to be adapted to the desired diameter of the fabric formation 6, 11, so that the respective projections 15 are cut off using a knife 16 according to the right-hand side of the figure 5 are separated. Consequently, the outer circumferences of the fabric 6, 11 and the carrier layer 4 are aligned with one another.

Zudem ist die Bohrung 3 des Gewebes 6, 11 und der Trägerschicht 4 an die vorgegebenen Durchmesser der Reinigungsgeräte anzupassen. Im Betriebszustand ist die Trägerschicht 4 der Antriebsscheibe des Reinigungsgeräts zugewandt und steht mit dieser in einer trieblichen Wirkverbindung. Die aus den Melaminharz-Schaum-Partikeln 6 und den Polyester-non-woven-oder Klett-Material-Stücken 11 bestehenden Gewebe sind dem Untergrund zugewandt.In addition, the bore 3 of the fabric 6, 11 and the carrier layer 4 must be adapted to the specified diameter of the cleaning device. In the operating state, the carrier layer 4 faces the drive pulley of the cleaning device and is operationally connected to it. The fabric consisting of the melamine resin foam particles 6 and the polyester non-woven or Velcro material pieces 11 face the ground.

Da die Reinigungsscheibe 1 nunmehr aus einem Gewebe aus Partikeln 6 und Stücken 11 aus unterschiedlichen Materialien besteht, können die Reinigungseigenschaften an die jeweilige Untergrundbeschaffenheit angepasst sein. Je härter der Untergrund bzw. dessen Oberfläche ist, desto mehr Anteil von Melamin-Harzschaum-Partikeln 6 sind in dem Gewebe vorhanden. Der Anteil von Melamin-Harzschaum-Partikeln 6 kann dabei zwischen 10 % und 90 % liegen. Die Polyester-non-woven-Stücke 11 werden in entsprechender Weise gemäß Figur 1 in den Mischer 12 eingefüllt. Die Formstabilität der Reinigungsscheibe 1 ist durch die Trägerschicht 4 erreicht.Since the cleaning disk 1 now consists of a fabric made of particles 6 and pieces 11 made of different materials, the cleaning properties can be adapted to the respective surface conditions. The harder the substrate or its surface, the more melamine resin foam particles 6 are present in the fabric. The proportion of melamine resin foam particles 6 can be between 10% and 90%. The polyester non-woven pieces 11 are provided in a corresponding manner figure 1 poured into the mixer 12. The dimensional stability of the cleaning disc 1 is achieved by the carrier layer 4 .
