Abstract

The device has a container for a cleaning fluid, and has equipment which is arranged outside the fluid, in order to support the sponge (2) while it is being squeezed. The force which is necessary to squeeze the sponge is generated by a pressing roller (7,8,9), and the device has conveyor equipment (4) in order to move the plate from the cleaning fluid to the supporting equipment. The latter is a pressing roller (6) which supports the sponge in a position from which it can be withdrawn. The conveyor equipment may be driven by an electric motor (18), and may have at least one conveyor belt (5).

Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen einer einen Schwamm aufweisenden Schwammscheibe mit einem Behälter für Reinigungsflüssigkeit und mit außerhalb der Reinigungsflüssigkeit angeordneten Mitteln zum Abstützen des Schwamms beim Ausdrücken.The invention relates to a device for cleaning a sponge disc having a sponge with a container for cleaning liquid and with means arranged outside the cleaning liquid for supporting the sponge when squeezing out.

Solche Vorrichtungen werden insbesondere zum Reinigen von Schwammscheiben eingesetzt, welche zum Abwaschen von frisch verfugten Fliesen einer Wand oder eines Bodens vorgesehen sind. Die Schwammscheibe hat in der Regel einen auf einem Brett montierten Griff und an der dem Griff abgewandten Seite des Brettes den Schwamm. Eine aus der Praxis bekannte Vorrichtung hat als Mittel zum Abstützen des Schwamms beim Ausdrücken zwei auf dem Behälter mit Reinigungsflüssigkeit befestigte Rollen. Zur Reinigung taucht man die Schwammscheibe in die Reinigungsflüssigkeit ein und rollt sie anschließend über die Rollen. Hierbei wird eine zum Ausdrücken des Schwamms erforderliche Anpresskraft von Hand aufgebracht. Dieser Vorgang wird mehrmals wiederholt, bis der Schwamm gründlich gereinigt ist. Das Reinigen des Schwamms ist mit der bekannten Vorrichtung jedoch sehr zeitaufwendig und nimmt häufig genauso viel Zeit in Anspruch, wie das Abwaschen der Fliesen. Zur Vermeidung eines verbleibenden Grauschleiers auf den Fliesen muss das Abwaschen der Fliesen und das Reinigen des Schwamms möglichst schnell erfolgen. Eine Reinigung der Schwammscheibe, während man mit einer zweiten Schwammscheibe die Fliesen abwäscht, ist mit der bekannten Vorrichtung ohne zusätzliche Hilfskraft nicht möglich.Such devices are used in particular for cleaning sponge disks, which are provided for washing freshly grouted tiles on a wall or floor. The sponge disc usually has a handle mounted on a board and the sponge on the side of the board facing away from the handle. A device known from practice has two rollers attached to the container with cleaning liquid as a means for supporting the sponge when it is squeezed out. For cleaning, immerse the sponge disc in the cleaning liquid and then roll it over the rollers. Here, a pressing force required to squeeze out the sponge is applied by hand. This process is repeated several times until the sponge is thoroughly cleaned. However, cleaning the sponge with the known device is very time-consuming and often takes just as much time as washing the tiles. To avoid a remaining gray haze on the tiles, wash the tiles and clean the sponge as quickly as possible. A cleaning of the sponge disc while washing the tiles with a second sponge disc is with the known device not possible without additional help.

Der Erfindung liegt das Problem zugrunde, eine Vorrichtung der eingangs genannten Art so zu gestalten, dass sie die Schwammscheibe besonders zuverlässig reinigt, ohne die Aufmerksamkeit einer die Fliesen abwaschenden Person zu erfordern.The invention is based on the problem of designing a device of the type mentioned at the outset in such a way that it cleans the sponge disk particularly reliably without requiring the attention of a person washing the tiles.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass sie Andrückmittel zum Erzeugen einer erforderlichen Andrückkraft beim Ausdrücken des Schwamms und eine Fördereinrichtung zur Bewegung der Schwammscheibe aus der Reinigungsflüssigkeit zu den Mitteln zum Abstützen des Schwamms und in eine außerhalb der Reinigungsflüssigkeit befindliche Entnahmeposition aufweist.This problem is solved according to the invention in that it has pressing means for generating a required pressing force when squeezing the sponge and a conveying device for moving the sponge disk from the cleaning liquid to the means for supporting the sponge and into a removal position located outside the cleaning liquid.

Durch diese Gestaltung wird die Schwammscheibe einfach in den Behälter mit der Reinigungsflüssigkeit gelegt. Hierbei nimmt der Schwamm der Schwammscheibe Reinigungsflüssigkeit auf. Die Fördereinrichtung bewegt die Schwammscheibe zu den Mitteln zum Abstützen des Schwamms, wo die zum Ausdrücken erforderliche Kraft aufgebracht wird, und schließlich in die Entnahmeposition. Dieser Vorgang kann beliebig oft wiederholt werden, bis die Schwammscheibe gründlich gereinigt ist. Da dieser Reinigungsvorgang keine oder nur eine geringe Aufmerksamkeit erfordert, kann man während dieser Zeit die Fliesen mit einer zweiten Schwammscheibe abwaschen. Anschließend wird die verschmutzte Schwammscheibe in die Reinigungsflüssigkeit gelegt und die saubere Schwammscheibe aus der Entnahmeposition entnommen. Dank der Erfindung lässt sich eine besonders große Fläche verfugter Fliesen von einer Person in sehr kurzer Zeit abwaschen. Da die Vorrichtung die zum Ausdrücken des Schwamms erforderliche Andrückkraft aufbringt, gestaltet sich die Reinigung der Schwammscheibe besonders ermüdungsfrei. Die erfindungsgemäße Vorrichtung eignet sich zur Reinigung einer nahezu beliebig gestalteten Schwammscheibe, welche beispielsweise einen besonders saugfähigen Schwamm oder einen mit einem relativ dünnen Vlies aufweist. Die Schwammscheibe kann weiterhin an ihrer Oberseite einen Handgriff, einen langen Stiel zur Reinigung der Fliesen im Stehen oder dergleichen aufweisen.With this design, the sponge disc is simply placed in the container with the cleaning liquid. The sponge in the sponge disc absorbs cleaning fluid. The conveyor moves the sponge disc to the means for supporting the sponge, where the force required for squeezing is applied, and finally to the removal position. This process can be repeated any number of times until the sponge disc is thoroughly cleaned. Since this cleaning process requires little or no attention, the tiles can be washed off with a second sponge during this time. The soiled sponge disc is then placed in the cleaning liquid and the clean sponge disc is removed from the removal position. Thanks to the invention, a particularly large area of grouted tiles can be washed off by a person in a very short time. Since the device applies the pressing force required to squeeze out the sponge, the cleaning of the sponge disk takes place particularly fatigue-free. The device according to the invention is suitable for cleaning an almost arbitrarily designed sponge disc, which has, for example, a particularly absorbent sponge or one with a relatively thin fleece. The sponge disc can also have a handle on its top, a long handle for cleaning the tiles while standing, or the like.

Der Antrieb der Fördereinrichtung könnte beispielsweise mit einer Handkurbel oder einem Hebel erfolgen. Zur Betätigung der Handkurbel oder des Hebels muss man jedoch das Abwaschen der Fliesen kurzzeitig unterbrechen. Eine Unterbrechung des Abwaschens lässt sich gemäß einer vorteilhaften Weiterbildung der Erfindung vermeiden, wenn die Vorrichtung einen Elektromotor zum Antrieb der Fördereinrichtung aufweist.The conveyor could be driven, for example, with a hand crank or a lever. To operate the hand crank or the lever, you have to briefly interrupt the washing of the tiles. An interruption of the washing can be avoided according to an advantageous development of the invention if the device has an electric motor for driving the conveyor.

Die Fördereinrichtung könnte beispielsweise mehrere in einer Reihe angeordnete, von dem Elektromotor angetriebene Rollen aufweisen. Hierdurch wird der Schwamm zuverlässig von der Fördereinrichtung erfasst und zu den Mitteln zum Abstützen des Schwamms bewegt. Die Fördereinrichtung besteht jedoch gemäß einer anderen vorteilhaften Weiterbildung der Erfindung aus wenigen Bauteilen und gestaltet sich konstruktiv besonders einfach, wenn die Fördereinrichtung zumindest ein Förderband aufweist.The conveyor could, for example, have a plurality of rollers arranged in a row and driven by the electric motor. As a result, the sponge is reliably gripped by the conveying device and moved to the means for supporting the sponge. According to another advantageous development of the invention, however, the conveyor device consists of a few components and is structurally particularly simple if the conveyor device has at least one conveyor belt.

Die Mittel zum Abstützen des Schwamms und die Andrückmittel gestalten sich gemäß einer vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn sie als Mittel zum Abstützen des Schwamms zumindest eine Ausdrückrolle oder ein Förderband und als Andrückmittel eine mit geringem Abstand oberhalb der Ausdrückrolle oder des Förderbandes angeordnete Andrückrolle aufweist. Durch diese Gestaltung wird die Schwammscheibe von der Fördereinrichtung zu der Ausdrückrolle bewegt und dabei von der Andrückrolle gegen die Ausdrückrolle oder das Förderband gedrückt. Die aus dem Schwamm ausgedrückte Reinigungsflüssigkeit läuft dabei an der Ausdrückrolle nach unten oder seitlich an dem Förderband vorbei.According to an advantageous development of the invention, the means for supporting the sponge and the pressing means are structurally particularly simple if, as means for supporting the sponge, they have at least one squeezing roller or a conveyor belt and as pressing means a pressure roller arranged at a short distance above the squeezing roller or the conveyor belt having. With this design, the sponge disc is removed from the conveyor moved to the squeezing roller and thereby pressed by the pressure roller against the squeezing roller or the conveyor belt. The cleaning liquid squeezed out of the sponge runs down the squeezing roller or past the conveyor belt.

Mit der erfindungsgemäßen Vorrichtung lassen sich unterschiedlich dicke Schwammscheiben reinigen, wenn der Abstand der Andrückrolle zu dem Förderband oder der Ausdrückrolle verstellbar ist.With the device according to the invention, sponge disks of different thicknesses can be cleaned if the distance between the pressure roller and the conveyor belt or the pressure roller is adjustable.

Die Schwammscheibe wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gründlich gereinigt, wenn sie eine Sprühanlage zum Besprühen des Schwamms mit Reinigungsflüssigkeit hat.According to another advantageous development of the invention, the sponge disc is cleaned particularly thoroughly if it has a spray system for spraying the sponge with cleaning liquid.

Verbrauchte Reinigungsflüssigkeit wird gemäß einer anderen vorteilhaften Weiterbildung von sauberer Reinigungsflüssigkeit getrennt, wenn die Vorrichtung eine Führung der aus dem Schwamm ausgedrückten Reinigungsflüssigkeit in einen zweiten, von dem Behälter mit Reinigungsflüssigkeit getrennten Behälter aufweist. Hierdurch wird schmutzige, aus dem Schwamm ausgedrückte Reinigungsflüssigkeit in den zweiten Behälter gelenkt. Die Reinigungsflüssigkeit bleibt hierdurch weitgehend sauber und wird bei Bedarf nachgefüllt.According to another advantageous development, used cleaning liquid is separated from clean cleaning liquid if the device has a guide of the cleaning liquid squeezed out of the sponge into a second container separated from the container with cleaning liquid. This directs dirty cleaning fluid squeezed out of the sponge into the second container. As a result, the cleaning liquid remains largely clean and is refilled if necessary.

Zur weiteren Verbesserung der Reinigung der Schwammscheibe trägt es bei, wenn die Vorrichtung gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine den Elektromotor schaltende Steuerungseinrichtung zum mehrmaligen Bewegen der Schwammscheibe in die Reinigungsflüssigkeit und zu den Mitteln zum Abstützen des Schwamms aufweist. Versuche haben gezeigt, dass eine zwei- bis dreimalige Wiederholung des Reinigungsvorganges zur zuverlässigen Reinigung der Schwammscheibe ausreicht.It helps to further improve the cleaning of the sponge disc if, according to another advantageous development of the invention, the device has a control device that switches the electric motor for moving the sponge disc several times into the cleaning liquid and for the means for supporting the sponge. Tests have shown that repeating the cleaning process two or three times is sufficient to reliably clean the sponge disc.

Die Vorrichtung ist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung kostengünstig herstellbar, wenn das Förderband aus Kunststoff gefertigt ist. Das Förderband zeichnet sich durch eine hohe Stabilität aus, wenn es eine Kette aus Metallgliedern hat.According to another advantageous development of the invention, the device can be produced inexpensively if the conveyor belt is made of plastic. The conveyor belt is characterized by high stability if it has a chain made of metal links.

Die in die Reinigungsflüssigkeit eingelegte Schwammscheibe wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders zuverlässig von dem Förderband erfasst, wenn das Förderband nach oben weisende Noppen zur Mitnahme der Schwammscheibe aufweist. Hierbei können eine Vielzahl von Noppen vorgesehen sein, die in den Schwamm einhaken und die Schwammscheibe mitführen. Alternativ dazu können auch wenige, besonders lang gestaltete Noppen vorgesehen sein, die die Schwammscheibe hintergreifen. Hierbei müsste der Abstand der Noppen größer sein als die Schwammscheibe lang ist.According to another advantageous development of the invention, the sponge disc inserted in the cleaning liquid is captured particularly reliably by the conveyor belt if the conveyor belt has knobs pointing upwards for taking the sponge disc with it. Here, a plurality of knobs can be provided which hook into the sponge and carry the sponge disc with it. As an alternative to this, a few particularly long nubs can also be provided which engage behind the sponge disc. The distance between the knobs should be larger than the sponge disc is long.

Die Schwammscheibe ist gegenüber den Andrückrollen sicher positioniert, wenn seitlich neben dem Förderband und/oder der Ausdrückrolle eine Führungsschiene zur Führung der Schwammscheibe angeordnet ist.The sponge disc is securely positioned with respect to the pressure rollers if a guide rail for guiding the sponge disc is arranged on the side next to the conveyor belt and / or the pressure roller.

Die Steuerung des Elektromotors gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn sie zum Schalten des Elektromotors in Abhängigkeit von der Position der Schwammscheibe ausgebildete Sensorelemente aufweist. Als Sensorelemente lassen sich beispielsweise von der Schwammscheibe zu betätigende Kontaktschalter einsetzen.According to another advantageous development of the invention, the control of the electric motor is particularly simple if it has sensor elements designed to switch the electric motor as a function of the position of the sponge disc. Contact switches that can be actuated by the sponge disk can be used as sensor elements, for example.

Die Sensorelemente sind gemäß einer anderen vorteilhaften Weiterbildung der Erfindung unempfindlich gegen Verschmutzung, wenn die Sensorelemente zur Erfassung der Position eines in der Schwammscheibe angeordneten Magneten ausgebildet sind. Hierfür eignen sich beispielsweise Reedkontakte als Sensorelemente.According to another advantageous development of the invention, the sensor elements are insensitive to contamination if the sensor elements are used to detect the position of a magnet arranged in the sponge disc are trained. For example, reed contacts are suitable as sensor elements.

Die Figur 1 zeigt eine in einem mit Reinigungsflüssigkeit gefüllten Behälter 1 angeordnete Vorrichtung zum Reinigen einer einen Schwamm 2 aufweisenden Schwammscheibe 3. Die Vorrichtung hat eine Fördereinrichtung 4 mit mehreren Förderbändern 5, 5a und eine Ausdrückrolle 6. Oberhalb der Förderbänder 5, 5a und der Ausdrückrolle 6 sind drei in einer Reihe angeordnete Andrückrollen 7 - 9 angeordnet.1 shows a device arranged in a container 1 filled with cleaning liquid for cleaning a sponge disc 3 having a sponge 2. The device has a conveyor device 4 with a plurality of conveyor belts 5, 5a and an ejection roller 6. Above the conveyor belts 5, 5a and the ejection roller 6, three pressure rollers 7 - 9 arranged in a row are arranged.

Die Figur 2 zeigt, dass auf jeder Seite der Vorrichtung jeweils drei Andrückrollen 7 - 12 angeordnet sind. Die Andrückrollen sind auf einer Wippe 13 in ihrer Höhe und ihrer Neigung verstellbar angeordnet. Die Förderbänder 5 weisen an ihrer Oberseite eine Vielzahl von Noppen 14 auf und werden von in einem Rahmen 15 der Vorrichtung gelagerten Rollen 16, 17 angetrieben. Eine der Rollen 17 der Förderbänder 5, 5a wird von einem Elektromotor 18 über einen Keilriemen 19 angetrieben. Der Rahmen 15 hat in seinen Endbereichen jeweils einen Endschalter 20, 21, deren Signale einer Steuerungseinrichtung 22 des Elektromotors 18 zugeführt werden. Die Schwammscheibe 3 wird seitlich von einer Führungsschiene geführt.FIG. 2 shows that three pressure rollers 7-12 are arranged on each side of the device. The pressure rollers are arranged on a rocker 13 in their height and their inclination adjustable. The conveyor belts 5 have a plurality of knobs 14 on their upper side and are driven by rollers 16, 17 mounted in a frame 15 of the device. One of the rollers 17 of the conveyor belts 5, 5a is driven by an electric motor 18 via a V-belt 19. The frame 15 has in its end regions each have a limit switch 20, 21, the signals of which are fed to a control device 22 of the electric motor 18. The sponge disc 3 is guided laterally by a guide rail.

Nach einem Einlegen der Schwammscheibe 3 in den Behälter 1 saugt der Schwamm 2 Reinigungsflüssigkeit auf. Anschließend betätigt die Schwammscheibe 3 den unteren Endschalter 21, wodurch der Elektromotor 18 eingeschaltet wird. Das Schalten des Elektromotors 18 kann wahlweise nach einer vorgegebenen Verzögerungszeit oder sofort erfolgen. Anschließend wird die Schwammscheibe 3 von den Förderbändern 5, 5a aus der Reinigungsflüssigkeit heraus zu der Ausdrückrolle 6 bewegt. Dabei drücken die Andrückrollen 7 - 12 die Schwammscheibe 3 gegen die Ausdrückrolle 6 und damit die Reinigungsflüssigkeit aus dem Schwamm 2 heraus. Die Andrückrollen 7 - 12 sind in Richtung der Ausdrückrolle 6 geringfügig geneigt. Hierdurch wird ein einfaches Einfädeln der Schwammscheibe 3 und ein kontinuierliches Ausdrücken des Schwamms 2 gewährleistet. Der Elektromotor 18 bewegt die Schwammscheibe 3 weiter, bis sie gegen den oberen Endschalter 20 gelangt. Anschließend wird der Elektromotor 18 umgeschaltet und bewegt die Schwammscheibe 3 wieder in die Reinigungsflüssigkeit zurück. Dieser Vorgang wiederholt sich zwei- bis dreimal. Anschließend schaltet der obere Endschalter 20 den Elektromotor 18 ab. Die Schwammscheibe 3 bleibt in der an dem oberen Endschalter 20 anliegenden Position liegen. Diese Position kennzeichnet die Entnahmeposition, in der sich die gereinigte Schwammscheibe 3 einfach von der Vorrichtung entnehmen lässt. Wenn man eine zweite Schwammscheibe in die Reinigungsflüssigkeit legt, saugt sich ihr Schwamm mit der Reinigungsflüssigkeit voll und gelangt gegen das Förderband 5. Nach Herausnahme der in der Entnahmeposition liegenden Schwammscheibe wird der Elektromotor 18 gestartet und die zweite Schwammscheibe gereinigt.After the sponge disc 3 has been inserted into the container 1, the sponge 2 absorbs cleaning liquid. Then the sponge disc 3 actuates the lower limit switch 21, whereby the electric motor 18 is switched on. The switching of the electric motor 18 can either take place after a predetermined delay time or immediately. The sponge disc 3 is then moved out of the cleaning liquid by the conveyor belts 5, 5a to the squeezing roller 6. The pressure rollers 7-12 press the sponge disc 3 against the pressure roller 6 and thus the cleaning liquid out of the sponge 2. The pressure rollers 7-12 are inclined slightly in the direction of the pressure roller 6. This ensures simple threading of the sponge disc 3 and continuous squeezing of the sponge 2. The electric motor 18 continues to move the sponge disc 3 until it reaches the upper limit switch 20. The electric motor 18 is then switched over and moves the sponge disk 3 back into the cleaning liquid. This process is repeated two to three times. The upper limit switch 20 then switches off the electric motor 18. The sponge disc 3 remains in the position in contact with the upper limit switch 20. This position characterizes the removal position in which the cleaned sponge disc 3 can easily be removed by the device. If a second sponge disc is placed in the cleaning liquid, its sponge soaks up the cleaning liquid and reaches the conveyor belt 5. After the sponge disc in the removal position has been removed, the electric motor 18 is started and the second sponge disc is cleaned.

Die Figur 3 zeigt eine erfindungsgemäße Vorrichtung mit einer Sprühanlage 24 zum Besprühen der Schwammscheibe 3 mit Reinigungsflüssigkeit. Die Sprühanlage 24 hat eine in dem Behälter 1 angeordnete Förderpumpe 25 und eine unterhalb des Förderbandes 5 angeordnete Spritzdüse 26. Das Förderband 5 besteht aus Ketten 27 mit Metallgliedern 28 und wird gemeinsam mit der Ausdrückrolle 6 von dem Elektromotor 18 über eine Kette 29 schlupffrei angetrieben. An den Enden der Führungsschiene 23 sind jeweils ein Sensorelement 30, 31 angeordnet, welche zur Erfassung der Position der Schwammscheibe 3 ausgebildet sind. Hierfür ist in der Schwammscheibe 3 ein Magnet 32 angeordnet. Die Sensorelemente 30, 31 erzeugen in Abhängigkeit einer Änderung des magnetischen Feldes ein elektronisches Signal, mit dem die Förderpumpe 25 und der Elektromotor 18 des Förderbandes 5 und der Ausdrückrolle 6 geschaltet wird. Hierdurch wird die Position der Schwammscheibe 3 verschmutzungsunabhängig erfasst. Unterhalb der Ausdrückrolle 6 ist ein weiterer Behälter 33 angeordnet, der aus dem Schwamm 2 der Schwammscheibe 3 ausgedrückte Reinigungsflüssigkeit aufnimmt.FIG. 3 shows a device according to the invention with a spray system 24 for spraying the sponge disk 3 with cleaning liquid. The spray system 24 has a feed pump 25 arranged in the container 1 and a spray nozzle 26 arranged below the conveyor belt 5. The conveyor belt 5 consists of chains 27 with metal links 28 and is driven together with the ejection roller 6 by the electric motor 18 via a chain 29 without slippage. At the ends of the guide rail 23 a sensor element 30, 31 are arranged, which are designed to detect the position of the sponge disc 3. For this purpose, a magnet 32 is arranged in the sponge disc 3. Depending on a change in the magnetic field, the sensor elements 30, 31 generate an electronic signal with which the feed pump 25 and the electric motor 18 of the conveyor belt 5 and the squeezing roller 6 are switched. As a result, the position of the sponge disc 3 is detected regardless of contamination. A further container 33 is arranged below the squeezing roller 6 and holds cleaning liquid squeezed out of the sponge 2 of the sponge disk 3.
