A continuously operating washing plant for mattresses, wherein the goods to be washed are led by means of a transportation device past a device effecting the washing mechanism and through several treating baths provided in tubs, characterized by that the tubs (1) for the various treating baths, as washing baths, disinfecting baths, or rinsing baths, are arranged one above the other.

Description

Die Erfindung betrifft eine kontinuierlich arbeitenden Waschanlage für Matratzen gemäß dem Oberbegriff des Patentanspruchs 1 insbesondere für Schaumstoffmatratzen.The invention relates to a continuously operating washing system for mattresses according to the preamble of claim 1, in particular for foam mattresses.

In Krankenhäusern ist es üblich, daß beim Patientenwechsel die Betten komplett desinfiziert werden. Dabei werden die Bettwäsche und meist auch die Bettgestelle gewaschen und desinfiziert. Die Matratzen jedoch werden mit wenigen Ausnahmen nur desinfiziert, daß heißt, sie werden nicht gewaschen. Dabei werden die in den Matratzen befindliche Verschmutzungen wie Harn, Blut, verschüttete Getränke und sonstige Substanzen nicht entfernt, sondern nur durch Erhitzen keimfrei gemacht. Der nächste Patient liegt dann auf desinfiziertem Schmutz, meist nur durch ein Bettuch getrennt.In hospitals it is common for beds to be completely disinfected when changing patients. The bed linen and mostly the bed frames are washed and disinfected. However, with a few exceptions, the mattresses are only disinfected, which means that they are not washed. The dirt in the mattresses such as urine, blood, spilled drinks and other substances are not removed, but only made germ-free by heating. The next patient then lies on disinfected dirt, usually only separated by a sheet.

Dies wird so gehandhabt, weil es bisher keine Waschmaschinen gibt, mit welchen man zu wirtschaftlich vertretbaren Kosten Matratzen waschen kann.This is done because there are no washing machines with which you can wash mattresses at an economically reasonable cost.

Die zahlreichen für Wäsche entwickelten Waschmaschinen können zwar auch Matratzen waschen, jedoch ist das Volumen der Matratzen im Verhältnis zur Wäsche viel zu groß, sodaß selten mehr als eine oder zwei Matratzen in eine Waschmaschine passen. Dadurch wird ein sehr geringe Leistung der Maschine bei sehr hohen Kosten erreicht. Daher werden meist nur besonders stark verschmutzte Matratzen gewaschen, oft noch von Hand und mit dem Wasserschlauch.The numerous washing machines developed for laundry can also wash mattresses, but the volume of the mattresses is far too large in relation to the laundry, so that rarely more than one or two mattresses fit into a washing machine. This results in very low machine performance at very high costs. For this reason, only particularly heavily soiled mattresses are washed, often by hand and with a water hose.

In der DE-A-1 920 307 wird zwar eine Wasch-und Trockenanlage für Matratzen beschrieben, bei welcher das Waschgut kontinuierlich durch verschiedene Behandlungsbäder gefördert und einer Waschmechanik unterzogen wird, diese Anlage ist aber in mancherlei Hinsicht für den Einsatz in Krankenhäusern oder dgl. nicht geeignet. Ein wesentlicher Nachteil besteht darin, daß die hintereinander liegenden Behandlungszonen eine sehr große Aufstellungsfläche erfordern, welche in der Regel in der Wäscherei nicht zur Verfügung steht. Darüberhinaus ist die Transportvorrichtung sowie die eigentliche mechanische Waschvorrichtung sehr aufwendig. Eine ausreichende mechanische Waschwirkung mittels Ultraschall-Erzeugung ist nicht gegeben. Aus den genannten Gründen dürfte sich diese Anlage auch nicht in der Praxis eingeführt haben.DE-A-1 920 307 describes a washing and drying system for mattresses in which the laundry is continuously conveyed through various treatment baths and subjected to a washing mechanism, but in many respects this system is suitable for use in hospitals or the like. not suitable. A major disadvantage is that the treatment zones located one behind the other require a very large installation area, which is generally not available in the laundry. In addition, the transport device and the actual mechanical washing device are very complex. A sufficient mechanical washing effect by means of ultrasound generation is not given. For the reasons mentioned, this system should not have been put into practice.

Der Erfindung liegt die Aufgabe zugrunde eine kontinuierlich arbeitende Waschanlage für Matratzen zu schaffen, die einfach im Aufbau ist und wenig Platz beansprucht, sodaß mit vertretbaren Kosten die Matratzen einwandfrei gereinigt werden können.The invention has for its object to provide a continuous washing system for mattresses, which is simple in construction and takes up little space, so that the mattresses can be cleaned properly with reasonable costs.

Erfindungsgemäß besteht eine solche Anlage aus mehreren übereinander angeordneten Wannen, die zur Aufnahme der Waschflüssigkeit, der Desinfektionsflüssigkeit und der Spülflüssigkeit dienen. Die Matratzen werden kontinuierlich durch mehrere Wannen hindurchgeführt, wobei sich die Vorschubgeschwindigkeit nach der notwendigen Waschzeit sowie nach der erforderlichen Einwirkungszeit des Desinfektionsbades richtet. Die Leistung der Anlage bestimmt sich daher bei gegebener Einwirkungszeit nach der Anzahl der übereinander angeordneten Wannen, wobei mehr Wannen eine größere Vorschubgeschwindigkeit erlauben und daher eine größere Stundenleistung ermöglichen.According to the invention, such a system consists of a plurality of trays arranged one above the other, which serve to hold the washing liquid, the disinfecting liquid and the rinsing liquid. The mattresses are continuously passed through several trays, the feed rate depending on the necessary washing time and the required exposure time of the disinfection bath. The performance of the system is therefore determined for a given exposure time according to the number of trays arranged one above the other, with more trays allowing a higher feed rate and therefore enabling a higher hourly output.

Um einen einwandfreien Durchlauf der Matratzen zu gewährleisten müssen die Wannen mit einer Transporteinrichtung versehen sein.To ensure that the mattresses run smoothly, the trays must be equipped with a transport device.

Den Vorschub besorgen vorzugsweise angetriebene Vorschubwalzen, welche von oben auf der Matratze aufliegen und leicht angedrückt werden.The feed is preferably provided by driven feed rollers, which rest on the mattress from above and are lightly pressed on.

Alternativ kann der Transport und der Vorschub auch durch angetriebene Gurte erfolgen.Alternatively, the transport and feed can also be carried out by driven belts.

In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel dargestellt.In the drawing, the invention is illustrated using an exemplary embodiment.

Gemäß Fig. 7 sind drei flache Wannen 1 übereinander angeordnet, durch welche die flach liegenden Matratzen mittels einer Transportvorrichtung geführt werden. Diese besteht aus einer Reihe von Vorschubwalzen 3, welche von oben auf der Matratze aufliegen und leicht angedrückt werden. Zur Verringerung des Gleitwiderstandes liegen die Matratzen auf Rollenbahnen 2. Die seitlichen Wangen der Wannen 1 sind so hoch, daß die auf den Rollenbahnen liegenden Matratzen von der Waschlüssigkeit bedeckt sind. Beim Austritt der Matratze aus einer Wanne wird diese durch Umlenkrollen 9 der nächsten Wanne zugeführt. Bei Anordnung der Behandlungsbäder übereinander werden die Matratzen von unten nach oben gefördert und die Wasch- und Spülbäder können den Einsatz von Pumpen im Gegenstrom genutzt werden. Dabei wird ein Teil des Spülwassers aus der obersten Wanne für das darunterliegende Klarwaschbad oder Desinfektionsbad genutzt, ein anderer Teil des Spülwassers und des Klarwaschwassers für die in der untersten von drei Wannen stattfindende Vorwäsche. Dieses Verfahren sichert niedrigen Wasserverbrauch und Dampfverbrauch.7, three flat tubs 1 are arranged one above the other, through which the flat mattresses are guided by means of a transport device. This consists of a series of feed rollers 3, which rest on the mattress from above and are pressed lightly. To reduce the sliding resistance, the mattresses lie on roller conveyors 2. The side cheeks of the tubs 1 are so high that the mattresses lying on the roller conveyors are covered by the washing liquid. When the mattress emerges from a tub, it is fed to the next tub by deflecting rollers 9. If the treatment baths are arranged one above the other, the mattresses are conveyed from bottom to top and the washing and rinsing baths can be used in countercurrent with pumps. Part of the rinse water from the top tub is used for the wash or disinfection bath underneath, another part of the rinse water and wash water is used for the prewash in the bottom of three tubs. This process ensures low water consumption and steam consumption.

Während des Durchlaufs durch die einzelnen Bäder müssen die Matratzen bewegt werden, um einen Austausch der von den Matratzen ausgesaugten Waschflüssigkeit mit der in der Wanne befindlichen freien Flüssigkeit zu erreichen.During the passage through the individual baths, the mattresses have to be moved in order to exchange the washing liquid sucked out of the mattresses with the free liquid in the tub to reach.

Die dazu notwendige Waschmechanik wird erzeugt, indem man die Matratzen in schneller Folge zusammenpresst und wieder freigibt. Dies geschieht durch Stauchwalzen 5 welche von oben die Matratze zusammendrücken und dann wieder freigeben Fig. 3. Dabei richtet sich die Häufigkeit der Walzenbewegung nach der gewünschten Stärke der Waschmechanik. Diese Stauchwalzen -sie stauchen die Matratzen zusammen- führen also eine senkrechte Bewegung von oben nach unten und von unten nach oben aus. Bei größeren Anlagen mit größerer Durchlaufgeschwindigkeit und dadurch notwendiger größerer mechanischer Einwirkung werden mehrere Walzen 6 auf einem umlaufenden Walzenkäfig angeordnet, welcher durch seine Drehung die einzelnen Walzen nacheinander auf die Matratze preßt und wieder abhebt (Fig. 4).The necessary washing mechanism is created by pressing the mattresses together in quick succession and releasing them again. This is done by upsetting rollers 5, which compress the mattress from above and then release it again. FIG. 3. The frequency of the roller movement depends on the desired strength of the washing mechanism. These compression rollers - they compress the mattresses - therefore perform a vertical movement from top to bottom and from bottom to top. In larger systems with a higher throughput speed and therefore a greater mechanical action, a plurality of rollers 6 are arranged on a rotating roller cage which, by its rotation, presses the individual rollers one after the other onto the mattress and lifts them again (FIG. 4).

Zum Entfernen grober Verschmutzungen werden eine oder mehrere Waschbürsten 7 eingesetzt wie man diese von Auto-Waschanlagen kennt (Fig. 5). Diese werden aber nur bei starker Verschmutzung eingeschaltet. Bei normaler Verschmutzung bleiben die Bürsten ausgeschaltet, um mechanische Schädigung der Matratze zu vermeiden.To remove coarse dirt, one or more washing brushes 7 are used, as is known from car washes (FIG. 5). However, these are only switched on when heavily soiled. With normal soiling, the brushes remain switched off to avoid mechanical damage to the mattress.

Zum einbringen des Frischwassers werden quer über die Wanne angeordnete dicht an der Matratze liegende Strahlrohre 8 benutzt, welche an der Unterseite zur Matratze hin Wasseraustrittsöffnungen haben (Fig. 8) . Durch den Druck, mit welchem das Spülwasser aus diesen Strahlrohren austritt, dringt es tief in die Matratze ein und erzeugt dadurch einen guten Spüleffekt.For introducing the fresh water, jet tubes 8 are used which are arranged transversely across the tub and lie close to the mattress and have water outlet openings on the underside towards the mattress (FIG. 8). Due to the pressure with which the rinsing water emerges from these jet pipes, it penetrates deep into the mattress and thus creates a good rinsing effect.

Die gleichen Strahlrohre kann man auch im Vorwaschbereich und im Waschbereich einsetzen, wodurch eine zusätzliche Waschwirkung erzeugt wird.The same jet pipes can also be used in the pre-wash area and in the wash area, which creates an additional washing effect.

Nachdem die Matratze die verschiedenen Waschbäder und das Spülbad durchlaufen hat, wird sie zwischen zwei Entwässerungswalzen 10 hindurchgeführt, bei welchen die obere Walze durch Federdruck oder pneumatischen Druck auf die untere Walze gedrückt wird. Dadurch wird der größte Teil des Wassers entfernt. Die in der Matratze verbliebene Restfeuchte wird in der Trocknungsvorrichtung 11 durch einen Warmluftstrom entfernt, welcher im Gegenstrom an der Matratze vorbeigeführt wird, nachdem diese die Entwässerungswalzen verlassen hat. Danach wird die Matratze aus der Anlage ausgestoßen und ist wieder verwendungsfähig.After the mattress has passed through the various washing baths and the rinsing bath, it is passed between two dewatering rollers 10, in which the upper roller is pressed onto the lower roller by spring pressure or pneumatic pressure. This will remove most of the water. The residual moisture remaining in the mattress is removed in the drying device 11 by a warm air flow, which is passed in counterflow to the mattress after it has left the dewatering rollers. Then the mattress is ejected from the system and can be used again.

In Fig. 2 ist angedeutet, daß im Bedarfsfalle die durch die Vorschubwalzen 3 bewirkte Transportbewegung durch einen umlaufenden Transportgurt 4 unterstützt werden kann.In Fig. 2 it is indicated that the transport movement caused by the feed rollers 3 can be supported by a circumferential conveyor belt 4 if necessary.

Die in die untere Wanne eingeschobene Matratzen durchlaufen kontinuierlich die einzelnen Behandlungsbäder, werden dabei durch die Vorschubwalzen 3 vorwärtsbewegt, durch die Stauchwalzen 5 bzw. 6 einer mechanischen Waschwirkung unterzogen, durch die Entwässerungswalzen 10 entwässert und anschließend getrocknet, sodaß sie fertig am anderen oberen Ende entnommen werden können.The mattresses inserted into the lower tub continuously pass through the individual treatment baths, are moved forward by the feed rollers 3, are subjected to a mechanical washing action by the upsetting rollers 5 and 6, are dewatered by the dewatering rollers 10 and then dried, so that they are removed at the other upper end can be.
