Seen in the running direction of the clearing drum, behind the upper end of the turning channel, discharge devices in the form of slides, belts or the like are provided in order to discharge the trays arriving in a more convenient, reversible position in terms of dishwashing technology, separately from the crockery parts, transversely to the direction of rotation of the turning drum into washing devices which are not described.

  • EP 0 292 773 A2 discloses a clearing system for used food trays, in which a turning drum with radial driver fingers, together with stationary, curved rails, also form a turning channel for the laundry, with axial flushing nozzles in the turning channel Prewashing is provided.
  • the trays are removed by means of a tray belt, which in the initial section guides the trays diagonally upward and then further horizontally into and through a dishwasher.
  • the crockery parts are placed obliquely downwards on a dishwasher conveyor belt via a slide underneath, which acts on the further prewash nozzles, which feeds the crockery parts to the dishwasher in a flat support position; a singular transport device is assigned to the lower feed chute, which clocks the crockery parts onto the dishwasher belt.

  • the items to be washed, which are fed into the actual dishwasher, are thus already freed from the coarsest soiling, which makes the washing station simple and shorter.
  • the outer turning belt is designed as a chain conveyor belt, in which the inner and outer centers are spaced apart from one another in a substantially parallel manner, and at the same time are parallel to one another at a distance from the inner belt, forming a turning channel with the latter.

Abstract

In the case of a dishwashing machine for trays loaded with dishes, with a separating station having a turning device, with an entry and delivery station and with a washing station, provision is made for the feeding conveyor to be a transverse conveyor belt (37) with a corner transfer device (39). In addition, the inner conveyor belt (1) of the turning conveyor is a grid belt which has an eccentric orbit, substantially pear-shaped in the carrying-off direction, and which is path-guided at its outer edge. The outer belt (2) is designed as a double chain conveyor belt, the inner and outer strands of which are spaced substantially parallel to one another and to the turning semicircle and are path-guided. The take-off belts (24, 25, 26) are present in the same number as articles to be washed (20, 21, 22) of different dimensions. Lastly, in the washing station (III) washing conveyor belts (44, 45, 46) are provided in a vertical arrangement parallel one above the other in such a way that they cooperate in each case with one of the take-off belts and convey the article to be washed, in laid-flat position, on through the washing, flushing and drying zones. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Geschirrspülanlage für mit Geschirrteilen beladene Tabletts, wie sie beispielsweise in Selbstbedienungsrestaurants, Betriebskantinen und anderen Großkantinen oder -restaurants eingesetzt werden.The invention relates to a dishwasher for trays loaded with dishes, such as those used in self-service restaurants, company canteens and other large canteens or restaurants.

Eine solche Anlage ist aus der DE-PS 34 13 480 bekannt, in der eine Geschirrspülanlage mit einer Zuführ-, einer Wende-, Sortier- und Abräumvorrichtung und das Hindurchführen des Waschgutes auf Bändern durch den Spülmaschinenteil der Anlage beschrieben ist. Die Tabletts mit daraufliegendem Geschirr werden mit deren kurzen Seite quer zur Achse der Wendevorrichtung in diese eingebracht (Queranordnung). Diese Wende- und Sortiereinrichtung besteht aus einer Wendetrommel, über die ein Förderband geführt ist, das nach außen weisende Fingerglieder besitzt, die in die zugeführten Geschirrteile mitnehmend eingreifen. Der Wendehalbkreis des inneren Förderbandes ist von einem Trum eines Gegenhalterungs-Bandes so umgriffen, daß dieses die zwischen die beiden Bänder eingebrachten beladenen Tabletts gegen die Fingerglieder des inneren Förderbandes gedrückt hält. Etwas versetzt vom oberen Scheitelpunkt des Wendehalbkreises bzw. der Wendetrommel, ist in Richtung auf den Spülmaschinenteil etwas zurückgesetzt ein Tablettförderer so angeordnet, daß er mit dem Förderband, auf dem die um 180° gewendeten Waschgutteile auf den Fingergliedern liegend aufgesetzt sind, die Tabletts abhebt und im wesentlichen horizontal durch den Spülmaschinenteil führt. Das in der Wendevorrichtung innere Förderband ist an seinem entgegengesetzten Verlaufsende soweit in Abtransportrichtung gezogen, daß die auf den Fingergliedern seines oberen Trums flach aufliegenden Geschirrteile in einem leicht abfallenden Winkel durch den gesamten Spülmaschinenteil hindurchbefördert werden.Such a system is known from DE-PS 34 13 480, in which a dishwasher with a feeding, a turning, sorting and clearing device and the passage of the laundry on belts through the dishwasher part of the system is described. The short side of the trays with the crockery lying on them are introduced into the axis of the turning device (transverse arrangement). This turning and sorting device consists of a turning drum, over which a conveyor belt is guided, which has outwardly pointing finger links, which engage in the dishes supplied. The turning semicircle of the inner conveyor belt is encompassed by a strand of a counter-holder belt so that it holds the loaded trays inserted between the two belts against the fingers of the inner conveyor belt. Slightly offset from the upper vertex of the turning semicircle or the turning drum, a tray conveyor is set back in the direction of the dishwasher part so that it is connected to the conveyor belt on which the items to be washed turned by 180 ° on the phalanges are placed in a horizontal position, the trays are lifted off and are guided essentially horizontally through the dishwasher part. The inner conveyor belt in the turning device is pulled at its opposite end so far in the removal direction that the crockery parts lying flat on the fingers of its upper run are conveyed through the entire dishwasher part at a slightly sloping angle.

Durch die Eingabe der beladenen Tabletts durch den Beschickungsförderer ganz knapp unterhalb der Wendetrommel, aus einem Bereich, in dem das äußere Gegenhalteband und das innere Förderband ohne festen Abstand zueinander aufeinander aufliegen, kann ein Verklemmen und durch die Antriebskraft der beiden Bänder auch ein Beschädigen der Tabletts und der Geschirrteile stattfinden. Des weiteren ist eher nachteilig, daß zum einen das mit Fingergliedern bestückte, relativ lange Förderband und zum anderen der Tablettförderer ständig durch den Spülmaschinenteil hindurchlaufen, wo sie großen Hitzeeinwirkungen und der Einwirkung sehr aggressiver Waschmittel ausgesetzt sind. Hierdurch leiden im hohen Maße insbesondere die Fingerglieder des inneren Wende- und Geschirr-Förderbandes, deren Lebensdauer demzufolge sehr gering ist. Auch kann durch das Hindurchleiten sämtlicher Geschirrteile mit Hilfe des mit Fingergliedern bestückten Bandes nur mit relativ niedriger Einspeisegeschwindigkeit gefahren werden, es sei denn, daß der Spülmaschinenteil eine relativ große Länge aufweist, was sich wiederum wegen hohen Platzbedarfs negativ auswirkt.If the loaded trays are entered by the loading conveyor just below the turning drum, from an area in which the outer counter-holding belt and the inner conveyor belt rest on each other without a fixed distance from one another, jamming and damage to the trays due to the driving force of the two belts can occur and the dishes take place. Furthermore, it is rather disadvantageous that, on the one hand, the relatively long conveyor belt equipped with phalanxes and, on the other hand, the tray conveyor continuously run through the dishwasher part, where they are exposed to great heat and the action of very aggressive detergents. As a result, the fingers of the inner conveyor belt and tableware conveyor belt suffer to a great extent, the service life of which is consequently very short. Also, by passing all the dishes with the aid of the belt equipped with finger links, the feed speed can only be relatively low, unless the dishwasher part has a relatively long length, which in turn has a negative effect due to the high space requirement.

Aus der DE-PS 24 43 651 ist ein Abräumgerät für benutztes Speisegeschirr bekannt, das ein Vorrichtungsteil zum Zuführen, Wenden und Sortieren des Waschgutes aufweist. Es ist eine um eine horizontale Achse umlaufende Abräumtrommel mit radialgestellten, an der Trommel angebrachten, elastischen Mitnehmerfingern, auf der eine Mehrzahl von ortsfesten, gebogenen Schienen gegenübersteht, die mit der Trommeloberfläche einen Wendekanal bilden. In Laufrichtung der Abräumtrommel gesehen, sind hinter dem oberen Ende des Wendekanals Abfördereinrichtungen in Form von Rutschen, Bändern oder dergleichen vorgesehen, um die in spültechnisch günstiger, gewendeter Lage ankommenden Tabletts getrennt von den Geschirrteilen quer zur Umlaufrichtung der Wendetrommel in nicht beschriebene Spüleinrichtungen abzuführen. Eine komplette Anlage, die eventuell eine platzsparende Gesamtanordnung aufweist, als auch ein möglicher Vorwaschgang, ist nicht beschrieben.From DE-PS 24 43 651 a clearing device for used dishes is known, which has a device part for feeding, turning and sorting the laundry. It is a clearing drum with a horizontal axis radially positioned, elastic driver fingers attached to the drum, on which a plurality of stationary, curved rails face each other, which form a turning channel with the drum surface. Seen in the running direction of the clearing drum, behind the upper end of the turning channel, discharge devices in the form of slides, belts or the like are provided in order to discharge the trays arriving in a more convenient, reversible position in terms of dishwashing technology, separately from the crockery parts, transversely to the direction of rotation of the turning drum into washing devices which are not described. A complete system, which may have a space-saving overall arrangement, as well as a possible prewash cycle is not described.

Des weiteren ist aus der EP 0 292 773 A2 (88 107 486.8) eine Abräumanlage für benutzte Speisetabletts bekannt, bei der ebenfalls eine Wendetrommel mit radialen Mitnehmerfingern zusammen mit ortsfesten, gebogenen Schienen einen Wendekanal für das Waschgut bilden, wobei in dem Wendekanal axiale Spüldüsen zum Vorwaschen vorgesehen sind. Die Abnahme der Tabletts erfolgt durch ein Tablettband, das im Anfangsabschnitt schräg nach oben und dann weiter horizontal die Tabletts in und durch eine Spülmaschine führt. Die Geschirrteile werden über eine darunterliegende Rutsche, auf die weiteren Vorwaschdüsen einwirken, schräg nach unten auf ein Spülmaschinen-Förderband aufgesetzt, das die Geschirrteile in Flachauflageposition der Spülmaschine zuführt; dabei ist der unteren Zuführrutsche eine Vereinzelungs-Transporteinrichtung zugeordnet, die die Geschirrteile auf das Spülmaschinenband eintaktet. Wie die Weiterführung in der Spülmaschine vorgenommen wird, ist nicht beschrieben. Der Vereinzelungs-Abnahmeteil dieser bekannten Vorrichtung ist relativ aufwendig aufgebaut und erfordert in Längserstreckung der Vorrichtung verhältnismäßig viel Platz.Furthermore, EP 0 292 773 A2 (88 107 486.8) discloses a clearing system for used food trays, in which a turning drum with radial driver fingers, together with stationary, curved rails, also form a turning channel for the laundry, with axial flushing nozzles in the turning channel Prewashing is provided. The trays are removed by means of a tray belt, which in the initial section guides the trays diagonally upward and then further horizontally into and through a dishwasher. The crockery parts are placed obliquely downwards on a dishwasher conveyor belt via a slide underneath, which acts on the further prewash nozzles, which feeds the crockery parts to the dishwasher in a flat support position; a singular transport device is assigned to the lower feed chute, which clocks the crockery parts onto the dishwasher belt. How it is continued in the dishwasher is not described. The separating acceptance part of this known device is relatively complex and requires a relatively large amount of space in the longitudinal direction of the device.

Auch wird durch die anfänglich schräg aufwärts wegtransportierten Tabletts eine größere Bauhöhe benötigt. Des weiteren ist eine vollautomatische Spülanlage für Geschirrtabletts bekannt, bei der die beladenen Tabletts über eine Rollenzuführbahn in eine Wendevorrichtung eintransportiert und in deren Wendekanal zwischen einem inneren und einem äußeren Förderband eingebracht werden. Das äußere Förderband, das bahngeführt ist mit beiden Trums parallel zueinander und in Höhe des Wendehalbkreises parallel zum ebenfalls banhgeführten Innenband, ist mit seinem einen Ende im wesentlichen bis zum Scheitelpunkt des Wendehalbkreises hochgezogen, während das andere Ende in einen horizontalen Einlaufteil ausläuft. Die Innenband-Bahn ist leicht birnenförmig und weist nach außen ragende Halte-/Mitnahme-Stäbe auf. Das Innenband ist als Gitterband ausgebildet, so daß während dem Wenden die Waschlast von innen her gleich vorgespült werden kann. Die Tabletts und Geschirrteile werden durch Abnahme- und Sortierbänder von der Wendeeinrichtung übernommen und an drei weitere, quer zur Zuführung, Wende- und Abnahmerichtung laufende Bänder abgegeben. Tabletts und Teller werden danach in vertikaler Anordnung durch eine Spülmaschine transportiert, während die Schalen durch eine weitere, parallel angeordnete Spülmaschine laufen. Es ist ersichtlich, daß hier eine sehr komplexe und äußerst viel Platz beanspruchende Anlage zum Einsatz kommt, die bei Großküchen mit geringeren Raummöglichkeiten nicht einsetzbar ist.A larger overall height is also required due to the fact that the trays are initially transported diagonally upwards. A fully automatic dishwashing system for dish trays is also known, in which the loaded trays are transported into a turning device via a roller feed path and are introduced into their turning channel between an inner and an outer conveyor belt. The outer conveyor belt, which is track-guided with both runs parallel to one another and at the level of the turning semicircle parallel to the likewise guided internal belt, is pulled up with one end essentially to the apex of the turning semicircle, while the other end ends in a horizontal inlet part. The inner band web is slightly pear-shaped and has holding / entraining rods that protrude outwards. The inner belt is designed as a mesh belt so that the wash load can be rinsed from the inside while turning. The trays and crockery parts are taken over by the turning and sorting belts from the turning device and delivered to three further belts running transversely to the feeding, turning and removing direction. Trays and plates are then transported in a vertical arrangement through a dishwasher, while the trays pass through another dishwasher arranged in parallel. It can be seen that a very complex and extremely space-consuming system is used here, which cannot be used in commercial kitchens with less space.

Der Erfindung liegt daher die Aufgabe zugrunde, die Vorrichtung eingangs genannter Art so zu verbessern, daß eine kompakte, robuste Anlage mit großer Leistungsfähigkeit, hoher Lebensdauer und geringem Raumbedarf geschaffen wird.The invention is therefore based on the object to improve the device of the type mentioned in such a way that a compact, robust system with great performance, long service life and low space requirement is created.

Diese Aufgabe wird erfindungsgemäß durch eine Geschirrspülanlage mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Aus- bzw. Weiterbildungen des Erfindunsgegenstandes werden in den Unteransprüchen beschrieben.This object is achieved by a dishwasher with the features of Claim 1 solved. Advantageous developments and further developments of the subject matter of the invention are described in the subclaims.

Demgemäß besitzt die erfindungsgemäße Geschirrspülanlage, die im wesentlichen aus einer Trennstation, einer Aus- und Eintragstation, einer Wasch-, Spül- und Trockenstation und einer Ausschubstation besteht, einen Beschickungsförderer, der ein Querförderband mit einem Eckumsetzer ist. Hierdurch wird der Vorteil erzielt, daß die Geschirrtabletts quer in die Anlage eingefördert werden können, so daß in der eigentlichen Wasch-, Spül- und Trockenstation wesentlich an aktiver Waschhöhe gewonnen werden kann.Accordingly, the dishwasher system according to the invention, which essentially consists of a separating station, an outfeed and infeed station, a washing, rinsing and drying station and an outfeed station, has a loading conveyor which is a cross conveyor belt with a corner converter. This has the advantage that the dish trays can be fed transversely into the system, so that in the actual washing, rinsing and drying station the active washing height can be substantially increased.

Erfindungswesentlich ist des weiteren, daß so viele Austragbänder vertikal übereinander angeordnet sind, wie Waschgutteile (z. B. Tabletts, Teller, Schalen) unterschiedlicher Außen-Querabmessung transportiert werden müssen. Zudem sind in der Wasch-, Spül-und Trockenstation jeweils mit einem der Austrag-Sortierbänder zusammenwirkende und das Waschgut jeweils flachliegend bis zur separaten End-Teileaustragung weiterführende Wasch-Transportbänder in Übereinander-Parallelanordnung vorgesehen. Hierdurch wird der große Vorteil erreicht, daß für das gesamte Waschgut, also beispielsweise Tabletts, Teller und Schalen, nur ein einziger Wasch-, Spül- und Trockentunnel benötigt wird, in dem die sortierten Tabletts und Geschirrteile in vertikal übereinander und gleichzeitig zueinander parallel angeordneten Bändern durch die Wasch-, Spül- und Trockenstationen geführt werden. Hiermit wird sehr viel Platz in Anlagen-Querrichtung eingespart, da nur eine und nicht zwei oder mehr nebeneinander angeordnete Waschtunnel bzw. Spülmaschinen verwendet werden. Durch die flache Anordnung des Waschgutes auf den vertikal übereinander angeordneten und parallel zueinander geführten Waschbändern besteht oft die Möglichkeit, diese Bänder in platzsparender Anordnung übereinander so anzuordnen, daß relativ wenig Bauhöhe benötigt wird und trotzdem noch eine sehr gute Wasch-, Spül- und Trockenbehandlung möglich ist.It is also essential to the invention that as many discharge belts are arranged vertically one above the other as items to be washed (eg trays, plates, bowls) of different external transverse dimensions have to be transported. In addition, in the washing, rinsing and drying station, washing conveyor belts, each cooperating with one of the discharge sorting belts and lying flat, are carried in a superimposed parallel arrangement until the separate end parts are discharged. This has the great advantage that only a single washing, rinsing and drying tunnel is required for the entire laundry, for example trays, plates and bowls, in which the sorted trays and dishes are arranged vertically one above the other and at the same time parallel to one another through the washing, rinsing and drying stations. This saves a lot of space in the transverse direction of the system, since only one and not two or more washing tunnels or dishwashers arranged side by side are used. Due to the flat arrangement of the items to be washed on the washing belts which are arranged vertically one above the other and run parallel to one another there is often the possibility of arranging these tapes one above the other in a space-saving arrangement in such a way that relatively little overall height is required and nevertheless a very good washing, rinsing and drying treatment is possible.

Vorteilhaft ist, wenn das Innen-Wendeband als Gitterband ausgebildet ist, das eine in Abtransportrichtung im wesentlichen birnenförmig exzentrische Umlaufbahn aufweist. Das Gitterband ist an seinem äußeren Rand durchgehend bahngeführt, wobei entlang des Wendehalbkreises durch dieses hindurchwirkende Radialdüsen für die Vorwäsche des Waschgutes vorgesehen sind. Dadurch ist der große Vorteil gegeben, daß das Innen-Wendeband relativ kurz und platzsparend ausgebildet und angeordnet ist. Durch die auf ein Minimum reduzierte Länge des Innenbandes, und insbesondere dadurch, daß das Innenband nicht auch durch die Wasch-, Spül- und Trockenanlage mit hohen Temperaturen und aggressiven Mitteln hindurchgeführt wird, wird eine hohe Lebensdauer des Bandes, das ein in seinen Anschaffungskosten nicht gerade billiges Teil ist, erreicht. Durch die Ausbildung des Innenbandes als Gitterband ist zudem die Möglichkeit gegeben, das vorbeigeführte Waschgut insbesondere über Radialdüsen vorzuwaschen. Das in die eigentliche Spülmaschine eingeförderte Waschgut ist somit bereits von den gröbsten Verschmutzungen befreit, wodurch die Waschstation einfach und kürzer gestaltet werden kann. Das Außen-Wendeband ist dabei als Kettenförderband ausgebildet, bei dem der Innen- und der Außentrum zueinander im wesentlichen parallel bahngeführt beabstandet, und zudem gleichzeitig parallel auf Abstand zum Innenband, mit diesem einen Wendekanal bildend, ausgerichtet sind. Da Innen- und Außenband synchron und entlang des Wendehalbkreises genau beabstandet laufen, sind optimale Einspeise- und Wendeeigenschaften sichergestellt. Dabei ist von Vorteil, wenn das Außenband mit an der Bandseite angeordneten Tablett-Mitnehmern ausgerüstet ist, so daß die Mitnahme der Tabletts nicht nur über die Kraft der in die Geschirrteile eingreifenden Finger des Innenbandes stattfindet, sondern gleichzeitig auch ein Anschieben bzw. Abstützen des transportierten Tabletts stattfindet. Dabei kann von großem Vorteil sein, wenn das Tablett vom Eckumsetzer auf den Horizontal-Übernahmeteil des Beschickungsbereichs des Außenbandes so aufgesetzt wird, daß das Tablett erst durch einen Mitnehmer des Bandes von z.B. seitlichen Auflageschienen abgezogen und in den Wendehalbkreis eingebracht wird.It is advantageous if the inner turning belt is designed as a grid belt which has an orbital eccentric orbital shape which is essentially pear-shaped in the direction of removal. The grid belt is continuously guided on its outer edge, radial nozzles acting through it being provided for prewashing the items to be washed along the turning semicircle. This has the great advantage that the inner turning belt is relatively short and space-saving and arranged. Due to the reduced length of the inner band, and in particular that the inner band is not also passed through the washing, rinsing and drying system with high temperatures and aggressive agents, a long lifespan of the band, which is not a cost in its purchase just cheap part is reached. The design of the inner belt as a mesh belt also gives the possibility of prewashing the items to be washed past, in particular via radial nozzles. The items to be washed, which are fed into the actual dishwasher, are thus already freed from the coarsest soiling, which makes the washing station simple and shorter. The outer turning belt is designed as a chain conveyor belt, in which the inner and outer centers are spaced apart from one another in a substantially parallel manner, and at the same time are parallel to one another at a distance from the inner belt, forming a turning channel with the latter. Since the inner and outer belts run synchronously and exactly spaced along the turning semicircle, optimal feeding and turning properties are ensured. It is advantageous if the outer belt is equipped with tray drivers arranged on the belt side, so that the Taking the trays not only takes place via the force of the fingers of the inner band engaging in the crockery parts, but at the same time pushing or supporting the transported tray takes place. It can be of great advantage if the tray is placed from the corner converter onto the horizontal take-over part of the loading area of the outer belt in such a way that the tray is only removed by a carrier of the belt from, for example, lateral support rails and inserted into the turning semicircle.

Um noch platzsparender zu bauen und gleichzeitig eine sichere Abnahme der Tabletts und Geschirrteile vom Innenband zu erreichen, ist das Außenband bzw. dessen obere Umlenkrolle in bezug auf den oberen Scheitelpunkt des Wendehalbkreises um bis zu 30° zurückgesetzt. Dadurch kann das obere Tablett-Austragband bis zum Scheitelpunkt des Wendehalbkreises gezogen sein, wodurch eine tangentiale Übernahme der Tabletts vom Scheitelpunkt des Wendehalbkreises stattfindet, so daß unter dem oberen Tablett-Austragband mehr Platz für die Anordnung weiterer Austragbänder verbleibt.In order to build even more space-saving and at the same time achieve a safe removal of the trays and dishes from the inner belt, the outer belt or its upper deflection roller is set back by up to 30 ° with respect to the upper vertex of the turning semicircle. As a result, the upper tray discharge belt can be drawn up to the apex of the turning semicircle, as a result of which the trays are taken over tangentially from the apex of the turning semicircle, so that more space remains for the arrangement of further discharge belts under the upper tray discharge belt.

Gemäß einer weiteren Ausbildungsform ist, wie bereits teilweise vorerwähnt, das erste Austragband das Tablettaustragband, das tangential vom oberen Scheitelpunkt des Wendehalbkreises horizontal weggeführt wird. Als zweites Band ist ein schräg nach unten führendes Band, das Schrägband, so vorgesehen, daß es mit seinem einen Ende zunächst sämtliche weiteren Geschirrteile des Waschgutes übernimmt und mit seinem unteren Ende mit dem untersten Waschband zusammenwirkt. Je nach weiterer Anzahl von Waschgutteilen unterschiedlicher Dimensionen sind eine entsprechende Anzahl von Zwischenaaustragbändern vorgesehen, die im wesentlichen horizontal verlaufend angeordnet sind und mit jeweils einem der Zwischenwaschbänder zusammenwirken. So können beispielsweise bei Vorhandensein von drei Waschgutteilen wie Tablett, Teller und Salatschalen, ein oberes horizontales Tablettband, ein Schrägband, das die Salatschalen dem unteren Waschband übergibt und ein horizontales Zwischen- oder Mittelband vorgesehen sein, das die Teller von dem Schrägband abnimmt und dem Zwischen-Waschband übergibt. Es sind folglich, je nach Anzahl der Waschgutteile, die gleiche Anzahl Austragbänder und die gleiche Anzahl Waschbänder vorgesehen.According to a further embodiment, as already mentioned above, the first discharge belt is the tray discharge belt, which is led away horizontally tangentially from the upper vertex of the turning semicircle. As a second band, a band leading obliquely downwards, the bias band, is provided in such a way that with one end it initially takes over all other dishes of the items to be washed and interacts with the bottom washing band with its lower end. Depending on the further number of laundry items of different dimensions, a corresponding number of intermediate discharge belts are provided, which are arranged essentially horizontally and each with one of the Intermediate washing tapes work together. For example, if there are three items to be washed, such as a tray, plate and salad bowls, an upper horizontal tray belt, a bias belt that transfers the salad bowls to the lower washing belt and a horizontal intermediate or central belt that removes the plates from the bias belt and the intermediate -Washer belt passes. Depending on the number of items to be washed, the same number of discharge belts and the same number of washing belts are therefore provided.

In Weiterbildung des Erfindungsgedankens können vom oberen Scheitelpunkt des Wendehalbkreises, nach Abnahme der Tabletts durch das obere Horizontalaustragband beidseitig auf das Schrägband zuleitende Einlaufschrägen vorgesehen sein, die die Geschirrteile so auf das abwärts führende Schrägband aufschieben, daß zumindest die größeren Teller relativ mittig und die Schalen bzw. Kleinteile sicher auf dem schmäleren Schrägband aufliegen. Dabei ist von großem Vorteil, wenn das Schräg-Austragband an seiner, die Geschirrteile tragenden Bandaußenseite, eine Antirutschausführung aufweist. Diese kann in verschiedenförmigen Profilierungen bzw. Erhebungen wie Querwülsten, Noppen usw., bestehen. Um ein Rutschen sowohl in Abwärtstransportrichtung auch ein seitliches Abrutschen vom Band zu verhindern, ist weiterhin vorteilhaft, wenn im Falle von Rillen oder Wülsten diese eine V-Anordnung so aufweisen, daß das V mit der Spitze in die Abwärtstransportrichtung weist.In a further development of the concept of the invention, from the upper apex of the turning semicircle, after removal of the trays by the upper horizontal discharge belt, bevels leading to the bias tape on both sides can be provided, which push the dishes onto the downward bias bias tape so that at least the larger plates are relatively centered and the bowls or Small parts rest securely on the narrow bias tape. It is of great advantage if the inclined discharge belt has an anti-slip design on the outside of the belt carrying the dishes. This can consist of differently shaped profiles or elevations such as transverse beads, knobs, etc. In order to prevent slipping both in the downward transport direction and a lateral sliding off the belt, it is also advantageous if, in the case of grooves or ridges, they have a V arrangement such that the V points with the tip in the downward transport direction.

Es besteht jedoch auch die Möglichkeit, daß das Schräg-Austragband in seinem ersten Teil, das heißt bis zum Beginn eines der nachfolgenden Zwischenaustragbänder, als Austrag-Rutsche ausgebildet ist, die seitliche Führungswände aufweist, die im Überlaufteil zu dem Schrägband als nach innen führende Einlaufschrägen ausgebildet sind. Es ist zu erkennen, daß es nur sinnvoll ist, die Austragrutsche bis zu einem ersten Zwischenband zu führen, da ansonsten eine zu lange Beschleunigungstrecke für die Geschirrteile vorhanden ist.However, there is also the possibility that the inclined discharge belt in its first part, that is, up to the beginning of one of the subsequent intermediate discharge belts, is designed as a discharge chute which has lateral guide walls which in the overflow part lead to the inclined belt as inwardly leading bevels are trained. It can be seen that it only makes sense to move the discharge chute up to a first one Intermediate conveyor to lead, otherwise there is too long an acceleration distance for the dishes.

Von besonderem Vorteil ist auch, wenn die Horizontal-Austragbänder alle als Kettenförderbänder ausgebildet sind. Hierdurch wird eine leichte, offene Bauweise erzielt, die günstig für den Abtransport der vorgespülten, tropfnassen Waschgutteile sind und zudem eine hohe Lebensdauer und niedrige Störanfälligkeit besitzen. Auch eine Gesamtreinigung der Anlage wird durch diese Ausführungsform erleichtert.It is also particularly advantageous if the horizontal discharge belts are all designed as chain conveyor belts. This results in a light, open construction which is favorable for the removal of the pre-rinsed, dripping wet items and also has a long service life and low susceptibility to failure. Overall cleaning of the system is also facilitated by this embodiment.

Des weiteren ist wirkungsvoll, wenn der Beschickungsförderer eine angetriebene Rollenbahn ist, die in Querrichtung der Anlage bzw. in Achsrichtung der Wendeeinrichtung die Tabletts einspeist und wenn als Eckumsetzer ein zwischen den letzten Rollen der Zuführbahn angeordnetes, in gleicher Richtung wie das Außenband wirksames, Tabletteinschubband vorgesehen ist. Dabei ist von Vorteil, wenn die Zuführrollenbahn an ihrem Transport-Ende einen Endanschlag längsseitig, also für die mit ihrer Schmalseite vorneweg ankommenden Tabletts, aufweist. Dieser Endanschlag ist in Abstimmung mit der Anordnung der in Eintransportrichtung hinteren Seitenführung des Außenbandes abgestimmt, so daß ein genaues Ab- bzw. Aufschieben des Außenbandes auf den Kettenförderer erreicht wird. Das Tabletteinschubband ist dabei im Verhältnis zum Endanschlag so zwischen den Förderrollen angeordnet, daß es im wesentlichen mittig an der Längsseite des Tabletts angreift und dieses einschiebt. Dabei kann ein sicheres, paralleles Einschieben der beladenen Tabletts erreicht werden, wenn entweder das Einschubband selbst und der Mitnehmer etwas breiter ausgelegt sind oder dieses zumindest einen breiteren Mitnehmer aufweist, um das Tablett auch sicher zu führen. Zu diesem Zwecke können jedoch statt einem mittigen Band, zwei Bänder vorgesehen sein, die synchron zueinander laufen und deren Mitnehmer praktisch gleichzeitig an der Längsseite je eines Tabletts angreifen und dieses sicher und senkrecht zur Eintransportrichtung abschieben.
Das Tabletteinschubband oder die Tabletteinschubbänder können mit jeweils einem oder mehreren Mitnehmern ausgerüstet sein. Dieses ist selbstverständlich abhängig von der Bandlänge, der Tabletteinschubgeschwindigkeit und den Abständen, in welchen die Tabletts vom Rollenband in die Anlage eingebracht werden.Furthermore, it is effective if the feed conveyor is a driven roller conveyor that feeds the trays in the transverse direction of the system or in the axial direction of the turning device and if a tablet insertion belt, which is arranged between the last rollers of the feed conveyor and is effective in the same direction as the outer belt, is provided as a corner converter is. It is advantageous if the feed roller conveyor has an end stop on the longitudinal side at its transport end, that is to say for the trays arriving with its narrow side at the front. This end stop is coordinated with the arrangement of the rear side guide of the outer belt in the direction of transport, so that an exact pushing or pushing of the outer belt onto the chain conveyor is achieved. The tablet insertion belt is arranged in relation to the end stop between the conveyor rollers in such a way that it engages in the middle of the long side of the tray and pushes it in. A safe, parallel insertion of the loaded trays can be achieved if either the insertion belt itself and the driver are designed to be somewhat wider or at least have a wider driver in order to safely guide the tray. For this purpose, however, instead of a central belt, two belts can be provided which run synchronously with one another and whose drivers are practical At the same time, grasp one of the trays on the long side and push it off securely and perpendicular to the direction of transport.
The tablet insertion belt or the tablet insertion belts can each be equipped with one or more drivers. Of course, this depends on the belt length, the tablet insertion speed and the intervals at which the trays are inserted into the system from the roller belt.

Selbstverständlich ist von besonderem Vorteil, wenn die verschiedenen Förderbänder, insbesondere das Querförderband des Beschickungsförderers und das Einschubband, in bezug auf die Abschubfrequenz mit der Födergeschwindigkeit der Wendeeinrichtung bis hin zu den Waschbändern abgestimmt sind.Of course, it is particularly advantageous if the various conveyor belts, in particular the cross conveyor belt of the loading conveyor and the insertion belt, are matched in terms of the push-off frequency with the conveyor speed of the turning device up to the washing belts.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels unter Bezug auf die Zeichnung näher erläutert.The invention is explained in more detail below using an exemplary embodiment with reference to the drawing.

Aus Figur 1 ist ersichtlich, daß die erfindungsgemäße Geschirrspülanlage aus mehreren, in Wasch- und gleichzeitig Längsrichtung hintereinander angeordneten Stationen besteht. So sind eine Trenn- und Vorwaschstation I, eine Ein- und Austragstation II, eine Wasch-, Spül- und Trockenstation III und eine Ausschubstation IV vorgesehen. In der Zeichnung, Fig. 1, ist insbesondere die Wasch-, Spül- und Trockenstation III wesentlich gekürzt dargestellt worden, so daß die einzelnen Unterstationen beispielsweise die Anordnung von zwei Waschstationen, gefolgt von einer Spülstation und einer Trockenstation, nicht erkennbar sind.From Figure 1 it can be seen that the dishwasher according to the invention consists of several stations arranged one behind the other in the washing and longitudinal directions. So are a separation and prewash station I, an entry and discharge station II, a washing, rinsing and drying station III and an extension station IV is provided. In the drawing, Fig. 1, the washing, rinsing and drying station III in particular has been shown significantly shortened, so that the individual substations, for example the arrangement of two washing stations, followed by a rinsing station and a drying station, cannot be seen.

Die Trenn- und Vorwaschstation I besteht im wesentlichen aus einem birnenförmigen, umlaufenden Innenband 1, das auf seinem kreisförmigen Umfang teilweise von einem Außenband 2 so umgeben ist, daß zwischen Innen- und Außenband ein Wendekanal 3 mit konstantem Querschnitt gebildet wird. Das Außenband 2 ist dem Grunde nach als Kettenförderband ausgebildet, das aus zwei parallel und synchron zueinander laufenden Ketten gebildet ist. Die Förderketten sind bahngeführt, so daß eine konstante Beabstandung auch zum Innenband sichergestellt ist.The separating and prewashing station I consists essentially of a pear-shaped, circumferential inner band 1, which is partially surrounded on its circular circumference by an outer band 2 such that a turning channel 3 with a constant cross section is formed between the inner and outer band. The outer belt 2 is basically designed as a chain conveyor belt, which is formed from two chains running parallel and synchronously to one another. The conveyor chains are track-guided so that a constant spacing from the inner belt is ensured.

Das Außenband 2 verläuft in einem ersten Beschickungsbereich 4 horizontal und geht am unteren Ende 6 des Wendekanals 3 in einen von der Seite gesehen halbkreisförmig gebogenen Bereich über. Dieser endet am oberen, auslaufseitigen Ende 5 des Wendekanals 3 bzw. verläuft über eine obere umlenkrolle 7 als Außentrum 10, im wesentlichen parallel mit dem Innentrum 9, bis zur unteren bzw. Antriebsrolle 8 zurückgeführt wird. Die Antriebsrolle 8 steht mit einem Antrieb 11 in trieblicher Verbindung.The outer belt 2 runs horizontally in a first loading area 4 and merges at the lower end 6 of the turning channel 3 into an area which is curved in a semicircular shape as seen from the side. This ends at the upper, outlet-side end 5 of the turning channel 3 or runs over an upper deflection roller 7 as the outer center 10, essentially parallel to the inner center 9, until it is returned to the lower or drive roller 8. The drive roller 8 is in drive connection with a drive 11.

Das Innenband 1 besteht aus einem endlosen, inneren Gitterband, das auf einer birnenförmigen Bahn unter Einschluß des Krümmungsmittelpunktes 12 des Wendehalbkreises geführt ist.An der dem Wendekanal 3 abgewandten Seite ist ein Zahnradpaar 13, durch einen Antrieb 14 drehbar angetrieben, angeordnet, die mit ihren Zähnen in das innere Gitterband für dessen Antrieb eingreifen. Die Drehrichtung des Innenbandes 1 ist durch einen Pfeil 15 dargestellt und verläuft im Gegenuhrzeigersinn um den Krümmungsmittelpunkt 12 herum, synchron zum inneren Trum 9 des außerhalb hinter den Wendekanal 3 angeordneten Kettenförderbandes des Außenbandes 2, dessen Umlaufrichtung durch einen gekrümmten Pfeil 16 dargestellt ist. Das Gitterband des Innenbandes 1 ist mit in gleichmäßigen Abständen nach außen ragenden Mitnehmerstäben 17 bestückt, die in die in den Wendekanal 3 eintransportierten Geschirrteile 20, 21, 22 eingreifen in diese stützen bzw. mitnehmen. Diese Mitnehmerstäbe 17 können eine zur Bahnebene im wesentlichen senkrechte bzw. in Wendehalbkreiszone radiale Ausrichtung aufweisen. Sie können aber auch eine in Transportrichtung nach vorne weisende Schrägausrichtung von 10°-20° besitzen. Die schräge Ausführungsform hat den Vorteil, daß gleichzeitig eine größere Halteelastizität vorhanden ist.The inner band 1 consists of an endless, inner lattice band, which is guided on a pear-shaped path including the center of curvature 12 of the turning semicircle. On the side facing away from the turning channel 3, a pair of gears 13, rotatably driven by a drive 14, is arranged, which with their Engage teeth in the inner mesh belt to drive it. The direction of rotation of the inner band 1 is by a Arrow 15 is shown and runs counterclockwise around the center of curvature 12, synchronously with the inner run 9 of the chain conveyor belt of the outer belt 2 arranged outside behind the turning channel 3, the direction of rotation of which is shown by a curved arrow 16. The mesh belt of the inner belt 1 is equipped with driving rods 17 which project outwards at uniform intervals and which engage in the dishes 20, 21, 22 which are transported into the turning channel 3 and support or take them with them. These driver bars 17 can have an orientation that is essentially perpendicular to the path plane or radial in the turning semicircle zone. However, they can also have an oblique orientation of 10 ° -20 ° pointing forward in the transport direction. The oblique embodiment has the advantage that at the same time there is greater holding elasticity.

Im Inneren der Wendeeinrichtung, und zwar mit Auswirkung im Wendehalbkreis, sind radial durch das Gitterband des Innenbandes 1 wirksame Vorwaschdüsen 18 angeordnet, die das im Wendekanal 3 vorbeigeführte Waschgut, bestehend aus Tabletts 20, die mit Tellern 21 und Schalen 22 beladen sind, vorwaschen, das heißt von groben Schmutz befreien.In the interior of the turning device, with an effect in the turning semicircle, effective prewash nozzles 18 are arranged radially through the mesh band of the inner band 1, which prewash the items of washing passed in the turning channel 3, consisting of trays 20 loaded with plates 21 and trays 22, that means getting rid of coarse dirt.

Es ist zu erkennen, daß das obere Ende 5 bzw. die Umlenkrolle 7 des Außenbandes 2 vom Scheitel 23 der Wändeeinrichtung am Umfang zurückgesetzt ist. Diese Zurücksetzung kann ca. 30° betragen und hat den Vorteil, daß zum einen an Bauhöhe gespart wird und zum anderen am Scheitel 23 keine baulichen Maßnahmen vorhanden sind, die einer Anbringung weiterer Bauteile, wie z.B. Austragbänder, im Wege stehen. Auch wird das durch die Bandlänge und damit zusammenhängend die Länge der Führungen gekürzt. Dabei sind keine Nachteile in bezug auf den Weitertransport des gewendeten Waschgutes zu befürchten, da dieses bereits sicher auf den Mitnahmestäben 17 aufsteht und über den Scheitel 23 hinwegtransportiert wird.It can be seen that the upper end 5 or the deflection roller 7 of the outer belt 2 is set back from the apex 23 of the wall device on the circumference. This reset can be approximately 30 ° and has the advantage that, on the one hand, the overall height is saved and, on the other hand, there are no structural measures at the apex 23 which stand in the way of attaching further components, such as discharge belts. This is also shortened by the length of the belt and the length of the guides. There are no disadvantages to fear with regard to the further transport of the turned laundry, because this already stands securely on the driving rods 17 and is transported over the apex 23.

In der Ein- und Austragstation II sind im oberen Teil Austragbänder 24, 25, 26 vorgesehen, über die das gewendete Waschgut von den Mitnehmerstäben 17 des Innenbandes 1 abgenommen und flachliegend an die Waschstation III weitergegeben werden.In the entry and discharge station II, discharge belts 24, 25, 26 are provided in the upper part, via which the turned laundry is removed from the carrier bars 17 of the inner belt 1 and passed flat to the washing station III.

Das obere Austragband 24 ist ein horizontales Tablettband 24, das als Doppel-Kettenband ausgebildet ist und das um zwei Umlenkräder 27 und 28 geführt ist. Das erste Umlenkrad 27 ist am Scheitel 23 tangetial zum Innenband so angeordnet, daß es das Innenband so umgreift, daß die Ketten des Tablettbandes 24 die Tabletts 20 von den Mitnehmerstäben 17 abhebt und horizontal wegfördert.The upper discharge belt 24 is a horizontal tray belt 24 which is designed as a double chain belt and which is guided around two deflection wheels 27 and 28. The first deflection wheel 27 is arranged at the apex 23 tangentially to the inner belt so that it engages around the inner belt so that the chains of the tray belt 24 lifts the trays 20 from the carrier bars 17 and conveys them away horizontally.

Unterhalb des Tablettbandes 24 ist, etwas tiefer ansetzend und in Umlaufrichtung des Innenbandes 1 versetzt, schräg eine Rutsche 29 angesetzt, die ebenfalls die Funktion einer Abfördereinrichtung hat und in ein Schrägband 25 mit gleicher Neigung übergeht. Es wird aus Figur 1 jedoch auch ersichtlich, daß das Schrägband 25 auch direkt bis zwischen die Mitnehmerstäbe 17 des Innenbandes greifend gezogen sein kann, wodurch eine Austragrutsche 29 entfällt. Das Schrägband wirkt an seinen unteren, über Umlenkräder 32 geführtes Ende, mit dem unteren Waschband zusammen.Below the tray belt 24, starting a little deeper and offset in the circumferential direction of the inner belt 1, a slide 29 is attached at an angle, which also has the function of a removal device and merges into a bias belt 25 with the same inclination. However, it can also be seen from FIG. 1 that the bias tape 25 can also be drawn directly as far as between the driver bars 17 of the inner tape, so that a discharge chute 29 is not required. At its lower end, which is guided via deflection wheels 32, the bias binding cooperates with the lower washing belt.

Das vertikal unterhalb des Tablettbandes 24 angeordnete, horizontale Mittelband 26 weist im wesentlichen den gleichen Anfang auf wie das Schrägband 25, das heißt, sie haben zumindest die gleiche Antriebsachse 30, auf der, selbstverständlich jeweils in Querrichtung versetzt, die entsprechenden Antriebsradpaare sitzen. Das Mittelband 26 verläuft an seinem entgegengesetzten Ende um Umlenkräder 31 und ist in gleicher Weise wie das Tablettband 24 als Doppelketten-Förderband für den Transport der Teller 21 ausgebildet. Zu beachten ist, daß die Umlenkräder 28, 31 und 32 vertikal übereinander angeordnet sind, also daß alle drei Austragbänder 24, 25 und 26 bis zur gleichen Vertikalebene und damit auf identischen Abstand zur Waschstation III, heranreichen. Dabei kann das Schrägband 25 ein Noppenband sein, das heißt, es kann ein normales Transportband mit rutscharmer Gummi- oder Kunststoffbeschichtung sein, auf dessen oberer Transportfläche beispielsweise Noppen 51 oder andere Erhebungen als Antirutschvorkehrung angeordnet sind. Das Schrägband 25 kann jedoch auch ein Gitterband, ähnlich wie das Innenband 1 sein, nur daß statt der relativ langen Mitnehmerstäbe 17 ganz kurze Halte-Noppen bzw. -höcker stöpselförmig herausragend so angeordnet sind, daß sie die Schalen 22 sicher gegen zu schnelles Abwärtsrutschen oder seitliches Wegrutschen festhalten.The horizontal central belt 26 arranged vertically below the tray belt 24 has essentially the same beginning as the bias belt 25, that is to say they have at least the same drive shaft 30 on which the corresponding drive wheel pairs are seated, of course offset in the transverse direction. The middle band 26 runs at its opposite end around deflection wheels 31 and is designed in the same way as the tray belt 24 as a double chain conveyor belt for the transport of the plates 21. It should be noted that the deflection wheels 28, 31 and 32 are arranged vertically one above the other, that is to say that all three discharge belts 24, 25 and 26 reach the same vertical plane and thus at an identical distance from the washing station III. The bias belt 25 can be a nub belt, that is, it can be a normal conveyor belt with a non-slip rubber or plastic coating, on the upper transport surface of which, for example, nubs 51 or other elevations are arranged as anti-slip measures. However, the bias tape 25 can also be a mesh tape, similar to the inner tape 1, only that instead of the relatively long driver bars 17, very short holding knobs or protrusions are arranged in a plug-shaped manner so that they reliably prevent the trays 22 from sliding down too quickly or Hold on to the side.

Aus Figur 1 ist des weiteren zu erkennen, daß vertikal oberhalb der Antriebsachse 30 für das Mittelband 26 und das Schrägband 25, Antriebsräder 33 für das Tablettband 24 angeordnet sind. Sowohl die Antriebsräder 33 als auch die Antriebsachse 30 sind über eine Antriebskette oder ein Band 35 mit einem Antrieb 34 trieblich verbunden. Es ist des weiteren zu erkennen, daß die Bandantriebe 11, 14, 34 miteinander gekoppelt sind bzw. koppelbar sind, so daß gleiche Bandgeschwindigkeiten vorgebbar sind.From Figure 1 it can also be seen that vertically above the drive axis 30 for the central belt 26 and the bias belt 25, drive wheels 33 are arranged for the tray belt 24. Both the drive wheels 33 and the drive axle 30 are operatively connected to a drive 34 via a drive chain or a belt 35. It can also be seen that the belt drives 11, 14, 34 are coupled to one another or can be coupled, so that the same belt speeds can be specified.

Wie aus Figur 2 ersichtlich ist, weist die Austrag-Rutsche 29 Einlaufschrägen 36 auf, die auf Breite des Schrägbandes 25 zulaufen und die auf der Rutsche 29 abwärts sich bewegenden Teller 21 und Schalen 22 praktisch zentrieren, so daß sie von den nachfolgenden Bändern, das heißt die Teller 21 vom Mittelband 26 und die Schalen 22 vom Schrägband 25 sicher positioniert übernommen werden können.As can be seen from FIG. 2, the discharge chute 29 has inlet bevels 36 which run to the width of the bias belt 25 and which practically center the plates 21 and trays 22 which move downwards on the chute 29, so that they are separated from the subsequent belts by the is called the plate 21 of Center belt 26 and the shells 22 can be safely positioned positioned from the bias belt 25.

Wie aus Figur 3 in Verbindung mit Figur 1 ersichtlich, ist im unteren Teil der Ein- und Austragstation II ein Querförderer 37 mit seiner Längsausdehnung benachbart zum vorderen Antriebsende des Beschickungsbereichs des Außenbandes angeordnet. Der Querförderer 37 besteht aus einem angetriebenen Rollenband 38, auf dem die Tabletts 20 mit ihrer Schmalseite voran, also in Längsaus richtung, eingebracht werden. Er weist des weiteren einen Eckumsetzer 39 auf, über den die ankommenden Tabletts genau positioniert und quer von der Rollenbahn ab und auf die Förderkette des Außenbandes 1 aufgeschoben werden.As can be seen from FIG. 3 in conjunction with FIG. 1, a transverse conveyor 37 is arranged in the lower part of the entry and discharge station II with its longitudinal extension adjacent to the front drive end of the loading area of the outer belt. The cross conveyor 37 consists of a driven roller belt 38, on which the trays 20 with their narrow side ahead, that is, introduced in the longitudinal direction. It also has a corner converter 39, via which the incoming trays are positioned exactly and pushed across the roller conveyor and onto the conveyor chain of the outer belt 1.

Der Eckumsetzer 39 besteht im wesentlichen aus einem Endanschlag 40, der in seiner Anschlagsfunktion genau mit der hinteren Seitenführung des Außenbandes 2 abgestimmt ist. Des weiteren enthält der Eckumsetzer 39 ein Tabletteinschubband 41, das zwischen zwei aufeinanderfolgenden Rollen der Rollenbahn 38 so angeordnet ist, daß es über mindestens einen auf der Oberseite angebrachten Mitnehmer 42 im wesentlichen mittig an der der Außenbahn abgewandten Längsseite eines Tabletts 20 angreift und dieses auf das Außenband 2 aufschiebt. Es ist zu erkennen, daß das Tabletteinschubband 41 im wesentlichen die gleiche Transportgeschwindigkeit aufweisen sollte wie das Außenband 2; es sei denn, daß im Beschickungsbereich 4 eine Art Aufschieb-Kufen oder -schienen zum schnelleren aufsetzen der Tabletts 20 vorgesehen sind, zu denen die Tabletts dann durch die Außenband-Mitnehmer 19 auf die Außenband-Ketten aufgeschoben werden.The corner converter 39 essentially consists of an end stop 40, the stop function of which is precisely coordinated with the rear side guide of the outer belt 2. Furthermore, the corner converter 39 contains a tablet insertion belt 41, which is arranged between two successive rollers of the roller conveyor 38 in such a way that it engages essentially centrally on the longitudinal side of a tray 20 facing away from the outer conveyor via at least one driver 42 mounted on the top side and this on the Slides on outer band 2. It can be seen that the tablet insertion belt 41 should have essentially the same transport speed as the outer belt 2; unless a kind of slide-on runners or rails are provided in the loading area 4 for faster placement of the trays 20, for which the trays are then pushed onto the outer belt chains by the outer belt drivers 19.

Wie aus Figur 1 des weiteren erkennbar ist, weist das dargestellte Einschubband 41 zwei Mitnehmer 42 auf, die auf der Bandaußenseite gleich beabstandet sind und eine Höhe aufweisen, die etwas über den Tablettrand herausragt, so daß eine sichere Mitnahme über den oberen Tablettrand erfolgen kann.As can also be seen from FIG. 1, the insertion belt 41 shown has two drivers 42 which are equally spaced on the outside of the belt and have a height, that protrudes slightly above the tablet edge so that it can be carried safely over the upper tablet edge.

Wie aus Fig. 1 auch zu ersehen ist, enden alle drei Austragbänder, nämlich das Tablettband 24, das Mittelband 26 und das Schrägband 25, vor jeweils einem Waschband 44, 45 bzw. 46. Die drei Waschbänder 44, 45, 46 gehören zur Waschstation III und führen die horizontal flachliegend übernommenen Waschgutteile 20, 21, 22 durch die entsprechenden Wasch-, Spül- und Trockenabteilungen hindurch, bis in die Ausschubstation IV. Die Waschbänder 44, 45, 46 sind ebenfalls Kettenbänder oder zumindest Gitterbänder, die zum einen für die aufgespritzten Wasch- und Spülmittel und die aufgeblasene Trockenluft sehr gut durchlässig sind, und zum anderen sehr wenig anfällig gegen die doch sehr aggressiven Waschmittel und die hohe Wärmeeinwirkung sind.As can also be seen from FIG. 1, all three discharge belts, namely the tray belt 24, the middle belt 26 and the bias belt 25, each end in front of a washing belt 44, 45 and 46. The three washing belts 44, 45, 46 belong to the washing station III and lead the horizontally lying flat laundry parts 20, 21, 22 through the corresponding washing, rinsing and drying departments through to the extension station IV. The washing belts 44, 45, 46 are also chain belts or at least mesh belts, which for one sprayed detergent and dishwashing liquid and the blown dry air are very permeable, and on the other hand very little susceptible to the very aggressive detergents and the high heat.

In der Ausschubstation IV sind, mit den jeweiligen Enden der Waschbänder 44, 45, 46 zusammenwirkend, ein oberer seitlicher Tablettausschub 47, ein zwischenliegender, seitlicher Tellerausschub 48 und eine untere Schalenaustragung 49 vorgesehen.In the extension station IV, interacting with the respective ends of the washing tapes 44, 45, 46, an upper lateral tray extension 47, an intermediate lateral plate extension 48 and a lower tray discharge 49 are provided.

Alle vier Hauptstationen I, II, III und IV sind in einem gemeinsamen Gehäuse 50 zusammengefaßt, das erkennbar in minimaler Höhe und Länge und auch relativ schmaler, die Tabletts nur wenig überschreitender Querbreite, auslegbar ist.All four main stations I, II, III and IV are combined in a common housing 50, which is recognizable in terms of minimum height and length and also relatively narrow, the width of the trays only slightly exceeding.
