Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Transport von Reinigungsgut durch eine Durchlaufspülmaschine sowie auf eine Durchlaufspülmaschine mit kontinuierlichem Transport des Spülgutes.The invention relates to a method for transporting items to be cleaned by a continuous dishwasher and to a continuous dishwasher with continuous transport of the items to be washed.

Die aus
Gemäß dieser Lösung wird die Durchlaufgeschirrspülmaschine, abgesehen von einem am Einlauf und am Auslauf angeordneten Transportband, von einem einzigen Transportband durchzogen. Alle Zonen, seien es die Waschzone, die Reinigungszone sowie eine Klarspülzone werden mit der gleichen Geschwindigkeit durchfahren. Gemäß dieser Lösung wird ein zyklischer nicht kontinuierlicher Transport des in der Durchlaufgeschirrspülmaschine zu reinigenden Reinigungsgutes vorgeschlagen, wobei ein schneller Transport kurze Einwirkungszeiten des Reinigungsfluides nach sich zieht, während beim Anhalten der Transporteinrichtung lange Einwirkzeiten erzielbar sind. Bei anderen Maschinen auf dem Markt wird das Spülgut kontinuierlich durch die Maschine transportiert. Bei diesen Maschinen gibt die verfahrenstechnisch langsamste Zone hinsichtlich der Transportgeschwindigkeit die Geschwindigkeit für alle weiteren Zonen der Maschine vor.According to this solution, the continuous dishwasher, apart from a arranged at the inlet and the outlet conveyor belt, of a single conveyor belt traversed. All zones, be it the washing zone, the cleaning zone or a final rinse zone are passed through at the same speed. According to this solution, a cyclic non-continuous transport of the cleaning material to be cleaned in the continuous dishwasher is proposed, whereby a rapid transport entails short exposure times of the cleaning fluid, while long exposure times can be achieved when the transport device is stopped. For other machines on the market, the items to be washed are continuously transported through the machine. In these machines, the slowest zone in terms of transport speed dictates the speed for all other zones of the machine.
Bei Durchlaufspülmaschinen erfordert zum Beispiel der Klarspülschritt, dass innerhalb einer möglichst geringen Zeit eine Mindestwassermenge auf das Spülgut aufgebracht wird, um einen ausreichend dicken Wasserfilm zum Abschwemmen von Partikeln zu erzeugen. Bei kleinen Transportgeschwindigkeiten einer Transporteinrichtung, wie beispielsweise eines kontinuierlich sich durch die Durchlaufspülmaschine bewegenden Transportbandes, wird bezogen auf die Anzahl der jeweiligen Spülgüter zu viel Klarspülwasser verbraucht, weil das Spülgut relativ lange im Bereich der Frischwasserklarspülung verbleibt.In continuous-flow dishwashers, for example, the rinsing step requires that a minimum amount of water is applied to the items to be washed within the shortest possible time in order to produce a sufficiently thick film of water to wash off particles. At low transport speeds of a transport device, such as a continuously moving through the continuous flow conveyor belt, is consumed based on the number of the respective items to be rinsed too much rinse water because the items remain relatively long in the fresh water rinse.
Ausgehend vom skizzierten Stand der Technik und des aufgezeigten technischen Problems, liegt der Erfindung die Aufgabe zugrunde, eine Durchlaufspülmaschine bereitzustellen, in der bei einer kontinuierlichen Transportgeschwindigkeit einer Transporteinrichtung die Dauer von Spül-, Klarspül- oder Trocknungsphasen optimiert werden kann. Erfindungsgemäß wird diese Aufgabe durch die Merkmale des unabhängigen Patentanspruches gelöst.Based on the outlined prior art and the technical problem outlined, the object of the invention is to provide a continuous-flow dishwasher in which the duration of rinsing, rinsing or drying phases can be optimized at a continuous transport speed of a transport device. According to the invention, this object is solved by the features of the independent claim.
Der erfindungsgemäß vorgeschlagenen Lösung folgend wird in einer der Behandlungszonen einer Durchlaufgeschirrspülmaschine eine direkt wirkende Sprühvorrichtung zum Eintrag eines Reinigungsmediums oder ein Spülsystem relativ zur Transportrichtung des Spülgutes durch die Durchlaufgeschirrspülmaschine bewegt. Die Relativbewegung des direkt wirkenden Sprühsystems für ein Reinigungsmedium oder eines Spülsystems zum Auftragen von Frischwasser und Spülflüssigkeit kann sowohl relativ in Transportrichtung des Spülgutes als auch relativ entgegen zur Transportrichtung des Spülgutes durch die Behandlungszonen der Durchlaufspülmaschine erfolgen.Following the solution proposed according to the invention, a direct-acting spray device for introducing a cleaning medium or a rinsing system relative to the transport direction of the ware is moved through the continuous-dish dishwasher in one of the treatment zones of a continuous dishwashing machine. The relative movement of the direct-acting spray system for a cleaning medium or a rinsing system for applying fresh water and rinsing liquid can be carried out both relatively in the transport direction of the ware and relatively opposite to the transport direction of the ware through the treatment zones of the continuous dishwasher.
Gemäß einer vorteilhaften Ausführungsvariante der erfindungsgemäß vorgeschlagenen Lösung kann ein Sprühsystem oder Spülsystem, welches von beiden Seiten auf das durch die Durchlaufspülmaschine transportierte Spülgut einwirkt auf einem Schlitten aufgenommen sein, der mittels eines separaten unabhängigen Antriebes relativ zur Transporteinrichtung, so zum Beispiel eines umlaufenden Transportbandes verschiebbar sein kann. Gemäß dieser Ausführungsvariante kann der Verfahrweg des Schlittens, an welchem das relativ zur Transporteinrichtung bewegbare Sprühsystem, Spülsystem oder das direkt wirkende Sprühsystem aufgenommen sind, in beide Richtungen durch Endschalter erfasst werden. Die Endschalter, die an den Endpunkten des jeweiligen Verfahrweges in Verfahrrichtung des Schlittens vorgesehen sind, stehen mit einer Maschinensteuerung in Verbindung. Über den ersten Endschalter kann zum Beispiel die Zeit erfasst werden, bis das Spülgut zum ersten Endschalter gelangt. Daraus kann die Transportgeschwindigkeit des Spülgutes durch die Maschinensteuerung errechnet werden. Abhängig von der ermittelten Transportgeschwindigkeit kann nunmehr der separate, den Schlitten antreibende Antrieb angesteuert werden und zum Beispiel das Frischwasserspülsystem, welches auf dem Schlitten aufgenommen ist, entweder in Transportrichtung des Spülgutes durch die Durchlaufspülmaschine verfahren oder entgegen der Transportrichtung des Spülgutes durch die Durchlaufspülmaschine verfahren. Dadurch wird in vorteilhafter Weise erreicht, dass bei Durchlaufspülmaschinen sowohl Frischwasser als auch zur Aufheizung des Frischwassers benötigte Heizenergie sowie Reinigungsmittel, d.h. eingetragene Chemie in beträchtlichem Umfange eingespart werden kann. Durch den ersten Endschalter wird nicht nur die Transportgeschwindigkeit des Spülgutes durch die Durchlaufspülmaschine erfasst, sondern gleichzeitig mit der Ansteuerung des separaten Antriebs für den Schlitten eine Pumpe, welche aufgeheiztes Frischwasser fördert und ein Magnetventil ansteuert. Abhängig von dem in der Maschinensteuerung errechneten Wert für die Transportgeschwindigkeit des Spülgutes durch die Durchlaufspülmaschine, wird von der Maschinensteuerung die Bewegungsgeschwindigkeit des Schlittens optimiert.According to an advantageous embodiment of the proposed solution according to the invention, a spray system or flushing system, which acts from both sides on the transported by the continuous dishwasher items to be taken on a carriage which be displaceable by means of a separate independent drive relative to the transport device, such as a revolving conveyor belt can. According to this embodiment variant, the travel path of the carriage, on which the spray system movable relative to the transport device, flushing system or the direct-acting spray system are accommodated, can be detected in both directions by limit switches. The limit switches, which are provided at the end points of the respective travel in the direction of travel of the carriage, are connected to a machine control. For example, the time can be detected via the first limit switch until the items to be washed reach the first limit switch. From this, the transport speed of the items to be washed can be calculated by the machine control. Depending on the determined transport speed, the separate drive driving the carriage can now be actuated and, for example, the fresh water rinsing system accommodated on the carriage either moved in the transport direction of the items to be washed by the continuous dishwasher or moved counter to the transport direction of the items to be washed by the continuous dishwasher. As a result, it is achieved in an advantageous manner that in continuous-flow dishwashers both fresh water and heating energy required for heating the fresh water and cleaning agents, i. considerable savings can be made in registered chemistry. By the first limit switch not only the transport speed of the items to be washed is detected by the continuous dishwasher, but at the same time with the control of the separate drive for the carriage a pump which promotes heated fresh water and drives a solenoid valve. Depending on the value calculated in the machine control for the transport speed of the items to be washed by the continuous dishwasher, the machine controller will optimize the movement speed of the slide.
Wird zum Beispiel der Schlitten innerhalb der Klarspülzone einer Durchlaufspülmaschine angeordnet, sind am Schlitten Frischwasserklarspülsysteme aufgenommen, die das Spülgut von dessen Oberseite und dessen Unterseite benetzen. Gelangt der Schlitten in eine durch einen zweiten Endschalter feststellbare Position, kann durch Erreichen des zweiten Endschalters der separate Antrieb reversiert werden, so dass der Schlitten und die darin aufgenommenen Frischwasserklarspülsysteme wieder ihre Ausgangsposition im Bereich des ersten Endschalters einnehmen. Gleichzeitig mit dem Erreichen des zweiten Endschalters durch das nunmehr klargespülte Spülgut, kann die Klarspülung ausgeschaltet werden, d.h. die Maschinensteuerung steuert das Magnetventil zur Frischwasserbeaufschlagung einer in der Klarspülzone einer Durchlaufspülmaschine vorgesehenen Pumpe.If, for example, the carriage is arranged within the final-rinse zone of a continuous-flow dishwasher, fresh-water rinsing systems are accommodated on the carriage, which wet the items to be washed from the upper side and the lower side thereof. If the carriage arrives in a position detectable by a second limit switch, the separate drive can be reversed by reaching the second limit switch, so that the carriage and the freshwater rinsing systems accommodated therein again assume their starting position in the region of the first limit switch. Simultaneously with the achievement of the second limit switch by the now clearly rinsed dishes, the rinse can be turned off, ie the machine controller controls the solenoid valve for fresh water admission of a pump provided in the final rinse zone of a continuous-flow dishwasher.
In einer weiteren Ausführungsvariante des der Erfindung zugrunde liegenden Gedankens, kann ein Direktsprühsystem oder ein Spülsystem wie zum Beispiel ein Frischwasserklarspülsystem innerhalb einer entsprechenden Behandlungszone der Durchlaufspülmaschine um eine Schwenkachse verschwenkt werden. Auch gemäß dieser Ausführungsvariante sind dann dem jeweils relativ zur das Spülgut aufnehmenden Transporteinrichtung der Durchlaufspülmaschine separat ansteuerbare Antriebe zugeordnet. Gemäß dieser Ausführungsvariante wird die Schwenkbewegung des Spülsystems oder des Direktsprühsystems durch Detektoren erkannt. Abhängig vom Erreichen eines ersten Detektors durch das Spülgut, wird der Schwenkantrieb aktiviert und kann nach Durchfahren der entsprechenden Behandlungszone detektiert durch einen am Ende der Behandlungszone angeordneten zweiten Detektor auch wieder abgeschaltet werden. Hinsichtlich zum Beispiel der Frischwasserbeaufschlagung eines derartigen relativ bewegbaren Spülsystems sei auf das im Zusammenhang mit der ersten Ausführungsvariante Gesagte verwiesen.In a further embodiment of the idea underlying the invention, a direct spray system or a flushing system such as, for example, a fresh water rinsing system can be pivoted about a pivot axis within a corresponding treatment zone of the continuous-flow dishwasher.

According to this embodiment, the pivoting movement of the flushing system or the direct spray system is detected by detectors. Depending on the arrival of a first detector through the items to be washed, the pivot drive is activated and, after passing through the corresponding treatment zone, can also be switched off again by a second detector arranged at the end of the treatment zone. With regard to, for example, the application of fresh water to such a relatively movable rinsing system, reference is made to what has been said in connection with the first embodiment variant.
Durch das Erreichen des ersten Detektors durch das Spülgut kann auch gemäß dieser Ausführungsvariante durch die Maschinensteuerung die Transportgeschwindigkeit des Spülgutes durch die Durchlaufspülmaschine errechnet werden. Abhängig von dem errechneten Wert für die Transportgeschwindigkeit kann die Bewegungsgeschwindigkeit, d.h. die Winkelgeschwindigkeit der Sprühsysteme um die Schwenkachse optimiert vorgegeben werden.By reaching the first detector through the items to be washed, the transport speed of the items to be washed can also be calculated by the continuous dishwasher according to this embodiment by the machine control. Depending on the calculated value for the transport speed, the movement speed, i. the angular velocity of the spray systems can be specified optimized around the pivot axis.
Mit den oben dargestellten Ausführungsvarianten des der Erfindung zugrunde liegenden Gedankens lassen sich, gleichgültig, ob in einer Spülzone, einer Pumpenklarspülzone oder einer Frischwasserklarspülzone eingesetzt, jeweils optimierte Einwirkzeiten sowie Wassermengen bzw. Reinigermengen erreichen, die einerseits die von der Durchlaufspülmaschine verbrauchte Wassermenge reduzieren, andererseits die Heizenergie auf das unbedingt notwendige Maß begrenzen und schließlich den Eintrag von Chemie in die erfindungsgemäß vorgeschlagene Spülmaschine erheblich herabsetzen.With the above-described embodiments of the invention underlying idea can be, regardless of whether used in a rinse zone, a Pumpenklarspülzone or a Frischwasserklarspülzone, respectively optimized exposure times and water quantities or detergent quantities reach, on the one hand reduce the amount of water consumed by the continuous dishwasher, on the other hand Limit heating energy to the absolutely necessary level and finally significantly reduce the entry of chemistry in the inventively proposed dishwasher.

In der Vorabräumzone 3 sind gemäß der Darstellung in
Der Vorabräumzone 3 ist eine Waschzone 4 nachgeschaltet. An Stelle der in
Der mindestens einen Waschzone 4 der Durchlaufspülmaschine 1 ist die Pumpenklarspülzone 5 nachgeschaltet. Innerhalb der Pumpenklarspülzone 5 befindet sich ein oberes Pumpenklarspülsystem 33 sowie ein unteres Pumpenklarspülsystem 34. Vom unteren Pumpenklarspülsystem 34 aus erstreckt sich ein Rücklauf 35 in einen Tank 36. Aus dem Tank 36 saugt eine Pumpe 37 Reinigungsfluid an und fördert dieses wiederum zum oberen Pumpenklarspülsystem 33 bzw. zum unteren Pumpenklarspülsystem 34. Auch die in der Pumpenklarspülzone 5 angeordnete Pumpe 37 steht mit der Maschinensteuerung 55 der Durchlaufspülmaschine 1 in Verbindung.The at least one
Der Pumpenklarspülzone 5 ist eine Frischwasserklarspülzone 6 nachgeschaltet.The
Innerhalb der Frischwasserklarspülzone 6 sind ein oberes Frischwasserklarspülsystem 41 sowie ein unteres Frischwasserklarspülsystem 42 angeordnet. Durch die Frischwasserklarspülsysteme 41, 42 wird das auf der Transporteinrichtung 11 aufgenommene Spülgut 10 in Transportrichtung 9 durch die Frischwasserklarspülzone 6 transportiert. In der in
Auch die direkt wirkenden Sprühsysteme, mit denen beispielsweise ein höher konzentrierter Reiniger in die Behandlungszonen 3, 4 oder 5 eingebracht wird, kann dem erfindungsgemäß vorgeschlagenen Konzept folgend, so innerhalb der jeweiligen Behandlungszone angeordnet werden, dass dieses ebenfalls relativ zur Transporteinrichtung 11 bewegt werden kann. Weiterhin ist auch denkbar, dass in der Trockenzone 7 angeordnete Trocknungsgebläse 51 relativ zum in Transportrichtung 9 transportierten Spülgut 10 zu bewegen, so zum Beispiel um eine Schwenkachse zu verschwenken.The direct-acting spray systems, with which, for example, a highly concentrated cleaner is introduced into the
Nachfolgend wird der der Erfindung zugrunde liegende Gedanke am Beispiel einer Frischwasserklarspülzone 6 der Durchlaufspülmaschine 1 detaillierter erläutert. Wie Figur 1 zu entnehmen ist, sind das obere Frischwasserklarspülsystem 41 und das untere Frischwasserklarspülsystem 42 auf einem verfahrbar ausgestalteten Schlitten 49 aufgenommen. Der Schlitten 49 kann zum Beispiel so ausgestaltet sein, dass dieser an seiner Unterseite eine Verzahnung aufweist, in welche ein über einen separaten Antrieb 50 antreibbares Zahnrad 57 eingreift. Je nach Rotationsrichtung des separaten Antriebes 50 kann auf diese Weise der Schlitten 49 innerhalb der Frischwasserklarspülzone 6 verfahren werden. Demzufolge sind auch die auf dem Schlitten 49 aufgenommenen Frischwasserklarspülsysteme 41 bzw. 42 innerhalb der Frischwasserklarspülzone 6 verfahrbar. Der Schlitten 49 kann in eine Verfahrrichtung 39 entgegen der Transportrichtung 9 der Transporteinrichtung 11 oder in eine Verfahrrichtung 40 mit der Transportrichtung 9 der Transporteinrichtung 11 bewegt werden.Hereinafter, the idea underlying the invention is explained in more detail using the example of a fresh
In Transportrichtung 9 des Spülgutes 10 gesehen, befindet sich im Eintrittsbereich der Frischwasserklarspülzone 6 ein erster Signalgeber 53. Der Endpunkt des Verfahrweges des Transportschlittens in Verfahrrichtung 39 entgegen der Transportrichtung 9, ist durch Bezugszeichen 44 gekennzeichnet. In Transportrichtung 9 des Spülgutes 10 durch die Durchlaufspülmaschine 1 gesehen, befindet sich im Austrittsbereich der Frischwasserklarspülzone 6 ein zweiter Signalgeber 54. Der Endpunkt des Verfahrweges 40 in Transportrichtung 9 des Spülgutes 10 durch die Durchlaufspülmaschine 1 ist durch Bezugszeichen 43 gekennzeichnet. Die auf dem verfahrbaren Schlitten 49 aufgenommenen Frischwasserklarspülsysteme 41, 42 sind über eine bewegliche Wasserzuführung 48 mit einer Pumpe 46 verbunden. Der Pumpe 46, die ihrerseits mit der Maschinensteuerung 55 verbunden ist, ist ein Magnetventil 47 vorgeschaltet, welches ebenfalls durch die Maschinensteuerung 55 betätigbar ist. Aus der Frischwasserklarspülzone 6 erstreckt sich ein Rücklauf 45 in den Tank 36, der der Pumpenklarspülzone 5 zugeordnet ist und in den überschüssiges Frischwasser aus der Frischwasserklarspülzone 6 abläuft. Das durch die Pumpe 46 dem oberen Frischwasserklarspülsystem 41 und dem unteren Frischwasserklarspülsystem 42 zugeführte Frischwasser kann sowohl vorgewärmt, d.h. in einem Boiler auf Temperatur gebracht sein oder es kann sich auch um Kaltwasser handeln.Seen in the
Der Vollständigkeit halber sei erwähnt, dass der Frischwasserklarspülzone 6 gemäß der Darstellung in
Nach Passage der mindestens einen Waschzone 4 bzw. der Pumpenklarspülzone 5, wird der Zeitpunkt des Eintritts des gereinigten Spülgutes 10 in die Frischwasserklarspülzone 6 durch den ersten Signalgeber 53 erfasst. Der erste Signalgeber 53 steht mit der Maschinensteuerung 55 in Verbindung. In der Maschinensteuerung 55 wird aus dem durch den ersten Signalgeber 53 erfassten Eintrittszeitpunkt des gereinigten Spülgutes 10 in die Frischwasserklarspülzone 6 die Transportgeschwindigkeit der Transporteinrichtung 11 errechnet, mit welcher das Spülgut 10 in Transportrichtung 9 durch die Durchlaufspülmaschine 1 transportiert wird. Gleichzeitig wird bei Detektion von Spülgut 10 durch den ersten Signalgeber 53 der separate Antrieb 50, mit welchem der Schlitten 49 angetrieben wird, angesteuert. Der Antrieb 50 bewegt den Schlitten 49 mit den daran aufgenommenen Frischwasserklarspülsystemen 41 bzw. 42 in Verfahrrichtung 39, d.h. entgegen der Transportrichtung 9 des Spülgutes 10 durch die Frischwasserklarspülzone 6. Durch den ersten Signalgeber 53 wird über die Maschinensteuerung 55 das Magnetventil 47 sowie die Pumpe 46 angesteuert, so dass die am Schlitten 49 aufgenommene Frischwasserklarspülsysteme mit Frischwasser beaufschlagt werden. Die Geschwindigkeit, mit der der Schlitten 49 bewegt wird, kann in Abhängigkeit von der in der Maschinensteuerung 55 ermittelten Transportgeschwindigkeit des Spülgutes 10 in Transportrichtung 9 hinsichtlich des Frischwasserverbrauchs optimal eingestellt werden. So ist sichergestellt, dass gerade die zum vollständigen Abschwemmen von Partikeln vom Spülgut 10 erforderliche Frischwassermenge in die Frischwasserklarspülzone 6 der Durchlaufspülmaschine 1 eingetragen wird.After passage of the at least one
Erreicht der Schlitten 49 mit den daran aufgenommenen Frischwasserklarspülsystemen 41, 42 den vorderen Endpunkt 44 in Verfahrrichtung 39 entgegen der Transportrichtung 9 des Spülgutes 10, wird der dem Schlitten 49 zugeordnete Antrieb 50 reversiert und verschiebt den Schlitten 49 in Verfahrrichtung 40, d.h. in Richtung der Transportrichtung 9 des Spülgutes 10, so lange bis der hintere Endpunkt 43 erreicht ist. Bei Erreichen des hinteren Endpunktes 43 und bei Detektion des Spülgutes 10 durch den zweiten Signalgeber 54 erfolgt eine Ansteuerung des Magnetventiles 47 durch die Maschinensteuerung 55 sowie ein Abschalten der Frischwasserförderpumpe 46, was ebenfalls durch die Maschinensteuerung 55 initiiert wird.If the
Von der Frischwasserklarspülzone 6 aus tritt das gereinigte und nun klargespülte Spülgut 10 in die Trocknungszone 7 ein, in der das die Frischwasserklarspülzone 6 verlassende Spülgut getrocknet und gegebenenfalls abgekühlt wird.From the fresh
