Abstract

1. 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 Waschanlage für Natratzen, insbesondere Schaumstoffmatratzen, bei welcher die Natratzen kontinuierlich durch flache, mit Transoorteinrichtungen für die Matratzen versehene Wannen geführt werden, welche mit Waschflüssigkeit. Desinfektionsmittel oder Frischwasser gefüllt sind, wobei die Matratzen während des Durchlaufs durch rotierende Bürsten, durch Stauchwalzen und durch Wasserstrahlrohre der notwendigen Waschmechanik ausgesetzt sind, und bei welcher die Matratzen nach dem Durchlaufen von Waschzone, Desinfektionszone und Spülzone durch eine walzenpresse entwässert und einen Warmluftstrom getrocknet werden.The invention relates to a washing system for sodium mattresses, in particular foam mattresses, in which the sodium mattresses are continuously guided through flat tubs provided with transor devices for the mattresses, which contain washing liquid. Disinfectant or fresh water are filled, whereby the mattresses are exposed to the necessary washing mechanics during the passage through rotating brushes, upsetting rollers and water jet pipes, and in which the mattresses are drained by a roller press after passing through the washing zone, disinfection zone and rinsing zone and a warm air stream is dried .

In Krankenhäusern ist es üblich, dass beim Patientenwechsel die Betten komulett desinfiziert werden. Dabei werden die Bettwäsche und meist auch die Bettgestelle gewaschen und desinfiziert. Die Matratzen jedoch werden mit wenigen Ausnahmen nur desinfiziert, das heisst, sie werden nicht gewaschen. Dabei werden die in den Matratzen befindlichen Verschmutzungen wie Harn, Blut, verschütete 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. With a few exceptions, however, 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. Die zahlreichen für Wäsche entwickelten Waschmaschinen können zwar auch Matratzen waschen, jedoch ist das Volumen der Matratzen im Verhältnis zu Wäsche viel zu gross, sodass selten mehr als eine oder zwei Matratzen in eine Waschmaschine passen. Dadurch wird eine sehr geringe Leistung der Maschine bei sehr höhen Kosten erreicht. Daher werden meist nur besonders stark verschmutzte Matratzen gewaschen, oft noch von Hand und mit dem Wasserschlauch.This is handled because there are no washing machines with which you can wash mattresses at an economically reasonable cost. The numerous washing machines developed for laundry can also wash mattresses, but the volume of the mattresses is far too large in relation to laundry, so that rarely more than one or two mattresses fit in a washing machine. This results in a very low machine performance at very high costs. Therefore, usually only become special heavily soiled mattresses washed, often by hand and with a water hose.

Die Aufgabe der Erfindng ist es eine Vaschanlage zu entwickln, welche in der Lage ist, zu vertretbaren Kosten die im Krankenhgus anfallenden Ketratzen zu Waschen, zu desinfizieren und zu trocknen.The object of the invention is to develop a washing system which is capable of washing, disinfecting and drying the ketraids occurring in the hospital at a reasonable cost.

Erfindungsgsgemäss besteht eine solche Anlame aus mehreren übereinander oder hintereinander angeordneten flachen Wannen, die zur Aufnahme der aschflüssigkeit, der Desinfektionsflüssigkeit und der Spülflässigkeit dienen. Die Matratzen werden kontinuierlich durch mehrere wannen hindurchgeführt, wobei sich die Vorschubgeschwindigkeit nach der notwendigen aschzeit sowie nach der erforderlichen Einwirkungszit des Pesinfektionsbades richtet. Die Leistung der Aniage bestimmt sich daher bei gegebener Einwirkungszeit nach der Anzahl der hintereinander oder übereinander angeordneten Wannen, wobei mehr Wannnen eine grösserer Vorschubgeschwindigkeit erlauben und daher eine prössere Stundenleistung ermöglichen.According to the invention, such an anlame consists of a plurality of flat troughs arranged one above the other or one behind the other, which serve to hold the ash liquid, the disinfectant liquid and the rinsing liquid. The mattresses are continuously passed through several trays, whereby the feed rate depends on the necessary ash time and the required exposure time of the pesinfection bath. The performance of the aniage is therefore determined for a given exposure time according to the number of troughs arranged one behind the other or one above the other, with more troughs permitting a higher feed speed and therefore enabling a higher hourly output.

Um einen einwandfreien Durchlauf der Matratzen zu gewährleisten müssen die Wannen mit einer Transoorteinrichtung versehen sein. Diese besteht entweder aus Rollenbahnen welche in der Wanne und daher in der Waschflüssigkeit liegen, wobei die seitlichen Wangen der Wanne so hoch sind, dass die Rollenbahn und die daraufliegende Matratze von der Waschflüssigkeit bedeckt sind. Den Vorschub besorgen angetriebene Vorschubwalzen, welche von oben auf der Matratze aufliegen und leicht angedrückt werden. Alternativ kann der Transport und der Vorschub auch durch angetriebene Gurte erfolgen. Beim Austritt der Matratze aus einer Wnne wird diese durch Umlenkrollen oder durch Umlenkgurte der nächsten Wanne zugeführt welche hinter oder über oder unter der ersten Wpnne angeordnet sein kann. Zweckmässig erscheint eine Ausführung, bei welcher die wannen übereinander liegen und bei welcher die Matratzen von unten nach oben gefördert werden, da bei dieser Anordnung die wasch- und Spülbäder ohne den Einsatz von Pumpen im Gegenstrom genutzt werden können. 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 Dsmofvervrauch.To ensure that the mattresses run properly, the tubs must be equipped with a transoor device. This consists either of roller conveyors which lie in the tub and therefore in the washing liquid, the side cheeks of the tub being so high that the roller conveyor and the mattress lying thereon are covered by the washing liquid. The feed is provided by driven feed rollers, which rest on the mattress from above and are lightly pressed on. Alternatively, the transport and feed can also be carried out by driven belts. Upon exit of the mattress from a Wnne it is carried by guide rollers or Umlenkgurte the next tray which fed behind or above or below the first W p nne may be disposed. An execution appears expedient in which the tubs are one above the other and the mattresses are conveyed from bottom to top, since with this arrangement the wash and rinse baths can be used in countercurrent without the use of pumps. Part of the rinse water from the top tub is used for the underlying wash or disinfection bath, 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 dsmof consumption.

Während des Durchlaufs durch die einzelnen Bäder müssen die Matratzen bewegt werden, um einen Austausch der von den Matratzen aufgesaugten 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 up by the mattresses with the free liquid in the tub.

Die dazu notwendige Jaschmechanik wird erzeugt, indem man die Matratzen in schneller Folge zusammenporesst und wieder freigibt. Dies geschieht durch Nalzen, welche von oben-die Matratze zusammendrücken und dann wieder freigeben. Dabei richtet sich die Häufigkeit der Walzenbewegung nach der gewünschten Stärke der Waschmechanik. Diese Stauchwalzen - sie stauchen die Matratze zusammen - führen also eine senkrechte Bewegung von oben nach unten und von unten nach oben aus. Bei grösseren Anlagen mit grosserer Durchlaufgeschwindigkeit und dadurch notwendiger grösserer mechanischer Einwirkung werden mehrere Walzen auf einem umlaufenden Walzenkäfig angeordnet, welcher durch seine Drehung die einzelnen Walzen nacheinander auf die Matratze presst und wieder abhebt.The necessary jash mechanics are created by piling up and releasing the mattresses in quick succession. This is done by tapping, which compress the mattress from above and then release it again. The frequency of the roller movement depends on the desired strength of the washing mechanism. These upsetting rollers - they compress the mattress - therefore perform a vertical movement from top to bottom and from bottom to top. In the case of larger systems with a higher throughput speed and, as a result, greater mechanical action, more rollers 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 off again.

Zum Entfernen grober Verschmutzungen werden eine oder mehrere Waschbürsten eingesetzt wie man diese von Auto-Waschanlagen kennt. Diese werden aber nur bei starker Verschmutzung eingeschaltet. Bei normaler Verschmutzung bleiben die Bürsten ausgeschaltet, um mechanische Schädigungen der Martratze zu vermeiden.To remove coarse dirt, one or more washing brushes are used, as is known from car washes. 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 Rohre benutzt, welche an der Unterseite zur Matratze hin Wasseraustrittsöffnungen haben. Durch den Druck, mit welchem das Spülwasser aus diesen Strahlrohren austritt, dringt es tief in die Matratze ein und erzeugt dadurch einen guten Spükeffekt.To introduce the fresh water, pipes are used which are arranged across the tub and are located close to the mattress and have water outlet openings on the underside towards the mattress. By pressure, with which the rinse water exits from these jet pipes, penetrates deep into the mattress and thus creates a good rinsing effect.

Die gleichen Rohre kann man auch im Vorwaschbereich und im Waschbereich einsetzen, wodurch eine zusätzliche Waschwirkung erzeugt wird.The same tubes 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 Naschbäder und das Spülbad durchlaufen het, wird sie zwischen zwei Entwässerugswalzen hindurchgefügrt, bei welchen die obere Walze durch Federdruck oder nneumatrschen Druck auf die untere Walze gedrückt wird. Dadurch wird der grösste Teil des Wassers entfernt. Die in der Matratze verbliebene Restfeuchte wird durch einen Narmluftstrom entfernt welcher im Gegenstrom an der Matratze vorbeigeführt wird, nachdem diese die Entwässerungswalzen verlassen hat. Danach wird die Matratze aus der Anlage ausarestossen und ist wieder verwendungsfähig.After the mattress has passed through the various nibbling baths and the rinsing bath, it is inserted between two dewatering rollers, 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 by an air flow which is passed in counterflow to the mattress after it has left the dewatering rollers. The mattress is then ejected from the system and can be used again.
