Die in den Figuren dargestellte und dort allgemein mit 1 bezeichnete Reinigungsmaschine dient zum Reinigen von Kästen 2 bzw. 2a, die zur Aufnahme von Behältern, beispielsweise Flaschen (Kasten 2) oder Dosen (Kasten 2a) bestimmt sind. Die Maschine 1 besteht im wesentlichen aus einem langgestreckten bzw. quaderförmigen Gehäuse 3, welches einen Innenraum bzw. Behandlungsraum 4 umschließt, in dem die zum Waschen und Reinigen der Kästen 2 bzw. 2a notwendigen Funktionselemente und Aggregate (insbesondere Tauchbad und Spritzdüsen) untergebracht sind. Der Innenraum 4 ist beispielsweise durch nicht dargestellte, an einer Längsseite des Gehäuses 3 vorgesehene großflächige, d.h. mannshohe Türen mit großen Fenstern zugänglich, durch die die Arbeitsweise der Maschine 1 einfach und übersichtlich überwachbar ist.The cleaning machine shown in the figures and designated generally by 1 is used to clean boxes 2 and 2a, respectively, which are intended to receive containers, for example bottles (box 2) or cans (box 2a). The machine 1 consists essentially of an elongated or cuboidal housing 3, which encloses an interior or treatment chamber 4, in which the necessary for washing and cleaning the boxes 2 and 2a functional elements and units (in particular immersion bath and spray nozzles) are housed. The interior 4 is, for example, by not shown, provided on a longitudinal side of the housing 3 large, ie. man-high doors with large windows accessible through which the operation of the machine 1 is easily and clearly monitored.

Zwischen einem an der in der Figur 1 linken Stirnseite 5 des Gehäuses 3 im unteren Bereich vorgesehenen Kasteneinlauf 6 und einem an der in dieser Figur an der rechten Stirnseite 7 im oberen Bereich vorgesehenen Kastenauslauf 8 ist eine bei der dargestellten Ausführungsform einspurige Fördereinrichtung gebildet, auf der die zu reinigenden Kästen 2 bzw. 2a durch den Innenraum 4 und an den an der Fördereinrichtung gebildeten Behandlungs- bzw. Waschelementen vorbei bewegt werden.Between one on the left in Figure 1 end face 5 of the housing 3 in the lower region provided in the box inlet 6 and on the in this figure at the right end 7 in the upper area provided box outlet 8 in the illustrated embodiment, a single-lane conveyor is formed on the the boxes 2 or 2a to be cleaned are moved past the interior 4 and past the treatment or washing elements formed on the conveyor.

Wie in der Figur 1 weiterhin dargestellt ist, besteht diese Fördereinrichtung im wesentlichen aus drei in vertikaler Richtung etagenartig übereinander angeordneten horizontalen Förderstrecken 9 - 11, auf denen die Kästen in Förderrichtung A bewegt werden und von denen die unterste Förderstrecke 9 als Tauchbad ausgeführt ist, in welchem die zu reinigenden Kästen 2 bzw. 2a in einer Reinigungsflüssigkeit untergetauch werden. Die mittlere Transportstrecke 10 und die obere Transportstrecke 11 sind jeweils von eigenständigen, endlos umlaufend angetriebenen Förderketten 12 (Figur 6) gebildet, die mit ihrer oberen, horizontalen Länge jeweils eine Standfläche für die Kästen 2 bzw. 2a bilden und die Transportebene TE der Transportstrecke definieren.As further illustrated in FIG. 1, this conveying device consists essentially of three horizontal conveying sections 9 - 11, which are stacked one above the other in the vertical direction and on which the boxes move in the conveying direction A. are and of which the lowermost conveyor line 9 is designed as an immersion bath, in which the boxes to be cleaned 2 and 2 are submerged in a cleaning liquid.

Die Förderstrecken 10 und 11 weisen weiterhin an den Längsseiten jeweils ein seitliches Führungsgeländer 13 auf, welches sich in horizontaler Richtung entlang der betreffenden Transportstrecke parallel zur Förderrichtung A erstreckt. Die als Scharnierbandketten ausgebildeten Förderbänder 12 sind jeweils so angetrieben, daß sich die notwendige Förderrichtung A für die Kästen 2 bzw. 2a ergibt, d.h. bei der für die Figur 1 gewählten Darstellung an der Transportstrecke 10 von rechts nach links und an der Transportstrecke 11 von links nach rechts.The conveyor sections 10 and 11 also have on the longitudinal sides in each case a lateral guide railing 13, which extends in the horizontal direction along the relevant transport path parallel to the conveying direction A. The conveyor belts 12 designed as hinge belt chains are each driven in such a way that the necessary conveying direction A for the boxes 2 or 2 a results, ie. in the representation selected for the figure 1 on the transport path 10 from right to left and on the transport path 11 from left to right.

Zwischen der Transportstrecke 9 und der Transportstrecke 10 sowie der Transportstrecke 10 und der Transportstrecke 11 ist jeweils ein Wende- oder Aufwärtsförderer 14 bzw. 15 vorgesehen, in dem die Kästen 2 bzw. 2a gewendet werden, so daß bei der dargestellten Ausführungsform die Kästen, die auf ihrem Boden aufstehend dem Kasteneinlauf 6 zugeführt werden, die als Tauchbad ausgebildete Transportstrecke 9 in dieser Orientierung durchlaufen, dann über den Aufwärtsförderer 14 gewendet, d.h. mit dem Kastenboden oben liegend an die Transportstrecke 10 übergeben werden und von dort über den Aufwärtsförderer 15 abermals gewendet, wieder mit dem Boden unten liegend über die Transportstrecke 11 an den Kastenauslauf 9 gelangen.Between the transport path 9 and the transport path 10 and the transport path 10 and the transport section 11, a respective turning or upward conveyor 14 and 15 is provided in which the boxes 2 and 2a are turned so that in the illustrated embodiment, the boxes standing on the floor of the box inlet 6 are supplied to the trained as an immersion bath transport path 9 in this orientation, then turned over the upward conveyor 14, ie lying with the box bottom lying on top of the transport section 10 and turned from there over the upward conveyor 15 again, again with the bottom lying down over the transport route 11 to the box outlet 9.

An den Transportstrecken 10 und 11 sowie auch an den Aufwärtsförderern 14 und 15 sind zur Behandlung der Kästen unter anderem Spritzdüsen 16 für die jeweilige Wasch- oder Behandlungsflüssigkeit (Wasser mit Reinigungszusätzen sowie Frischwasser zum Klarspülen usw.) vorgesehen.On the transport routes 10 and 11 and also on the upward conveyors 14 and 15, spray nozzles 16 for the respective washing or treatment liquid (water with cleaning additives and fresh water for rinsing etc.) are provided for the treatment of the boxes.

Die Aufwärtsförderer 14 und 15 sind jeweils als Klemmbackenförderer ausgebildet, in denen die Kästen 2 bzw. 2a seitlich durch Klemmen an Klemmbacken gehalten sind, die an umlaufend angetriebenen und an Rahmen oder Trägern 43 geführten Klemmbackenbändern 44 vorgesehen sind (fig. 7). Derartige Klemmbackenförderer sind dem Fachmann bekannt.The up-feeders 14 and 15 are each formed as a jaw conveyor in which the boxes 2 and 2a are held laterally by clamping jaws which are provided on circumferentially driven and guided to frame or carriers 43 jaw bands 44 (Fig. 7). Such jaw conveyors are known in the art.

An den Transportstrecken 10 und 11, aber auch an der Transportstrecke 9 ist jeweils ein oberes, als Niederhalter dienendes Führungsgeländer (Führungsschiene) 17 vorgesehen, welches sich oberhalb der jeweiligen Transportstrecke in einer die Transportrichtung A einschließenden vertikalen Mittelebene M vorgesehen ist.On the transport routes 10 and 11, but also on the transport path 9 is an upper, serving as hold-down guide rails (guide rail) 17 is provided, which is provided above the respective transport path in a transport direction A enclosing the vertical center plane M.

Wie in der Figur 1 auch dargestellt ist, besitzen die Kästen 2 und 2a unterschiedliche Größe und Höhe, wobei bei der dargestellten Ausführung die Kästen 2 übliche Flaschenkästen zur Aufnahme von Getränkeflaschen und die Kästen 2a aus einem geeigneten Material, beispielsweise aus Kunststoff hergestellte Trays zur Aufnahme von Dosen sind.As also shown in Figure 1, the boxes 2 and 2a have different size and height, in the illustrated embodiment, the boxes 2 usual crates for holding beverage bottles and the boxes 2a made of a suitable material, for example made of plastic trays for receiving of cans are.

Um mit ein und derselben Maschine Kästen unterschiedlicher Größe bzw. Höhe, beispielsweise die Kästen 2 und 2a behandeln zu können, und hierfür ein schnelles Umrüsten der Maschine 1 von einer Kastenhöhe auf eine andere Kastenhöhe zu ermöglichen, sind die Führungsgeländer 17 über eine Einstellvorrichtung in der Höhe, d.h. in vertikaler Richtung einstellbar, wie dies in den Figuren mit dem Doppelpfeil B angedeutet ist.In order to be able to handle with the same machine boxes of different size or height, for example, the boxes 2 and 2a, and this to allow a quick conversion of the machine 1 from a box height to another box height, the guide railings 17 via an adjustment in the Height, ie adjustable in the vertical direction, as indicated in the figures with the double arrow B.

Die für diese Höhenverstellung vorgesehene Verstellvorrichtung ist mehr im Detail in den Figuren 2 und 3 wiedergegeben und dort allgemein mit 18 bezeichnet. Für jedes Führungsgeländer 17 ist bei der dargestellten Ausführungsform eine eigene Verstellvorrichtung 18 vorgesehen. Diese besteht jeweils im wesentlichen aus einer oberen, als Stange ausgebildeten Hubschiene 19, die bei der dargestellten Ausführungsform von einem C- oder U-Profil gebildet und oberhalb der zugehörigen Führungsschiene 17 derart angeordnet ist, daß die offene Seite dieses Profils nach unten, d.h. in Richtung auf die Führungsschiene 17 weist. Die Hubschiene 19, die mit ihrer Längserstreckung parallel zur zugehörigen Führungsschiene 17 und gemeinsam mit dieser in der Mittelebene M angeordnet ist, ist in Längsrichtung, d.h. in horizontaler Richtung parallel zur Förderrichtung A um einen vorgegebenen Hub (Doppelpfeil C) verschiebbar. Hierfür sind an einem Rahmen 20 des Gehäuses 3 mehrere Rollen 21 um Achsen senkrecht zur Mittelebene M frei drehbar gelagert, und an von Rahmenelementen 20 nach unten wegstehenden flachen Armen 22. Auf diesen Rollen 21 liegt die Schiene 19 auf, und zwar zwischen den Armen 22 und damit durch diese gegen seitliches Herunterrutschen gesichert.The adjustment device provided for this height adjustment is reproduced in more detail in FIGS. 2 and 3 and designated there generally by 18. For each guide rail 17, a separate adjusting device 18 is provided in the illustrated embodiment. This consists essentially of an upper, designed as a rod stroke rail 19, which formed in the illustrated embodiment of a C or U-profile and above the associated Guide rail 17 is arranged such that the open side of this profile downwards, ie in the direction of the guide rail 17 has. The lifting rail 19, which is arranged with its longitudinal extent parallel to the associated guide rail 17 and together with this in the center plane M, in the longitudinal direction, ie in the horizontal direction parallel to the conveying direction A by a predetermined stroke (double arrow C) displaced. For this purpose, a plurality of rollers 21 freely rotatably supported about axes perpendicular to the median plane M on a frame 20 of the housing 3, and on frame members 20 downwardly projecting flat arms 22. On these rollers 21, the rail 19 is located, between the arms 22nd and thus secured by this against lateral slipping.

An der Verstell- oder Hubschiene 19 sind mehrere als Rollenketten ausgebildete Ketten 23 jeweils mit einem Ende befestigt, und zwar bei der dargestellten Ausführungsform bei jeder Verstellvorrichtung 18 insgesamt drei Ketten in gleichmäßigen Abständen derart, daß sich jeweils eine Kette 23 im Bereich jeden Endes der Schiene 19 bzw. der zugehörigen Führungsschiene 17 und eine Kette 23 sich in der Mitte der jeweiligen Schiene 19 bzw. Führungsschiene 17 befindet. Jede Kette 23 ist dabei mit ihrem oberen Ende zwischen den Schenkeln des U- bzw. C-Profils der Hubschiene 19 gehalten (Befestigungspunkt 24) und über eine diesem Befestigungspunkt 24 benachbarte Rolle 21 geführt, so daß jede Kette 23 über diese Rolle 21 nach unten hängt. Jede Kette 23 ist weiterhin mit ihrem unteren Ende bei 25 an der Oberseite der zugehörigen Führungsschiene 17 befestigt.On the adjustment or lifting rail 19 a plurality of chains formed as roller chains 23 are each attached with one end, in the illustrated embodiment at each adjustment 18 a total of three chains at equal intervals such that in each case a chain 23 in the region of each end of the rail 19 and the associated guide rail 17 and a chain 23 is located in the middle of the respective rail 19 and guide rail 17. Each chain 23 is held with its upper end between the legs of the U- or C-profile of the lifting rail 19 (attachment point 24) and guided over this attachment point 24 adjacent roller 21, so that each chain 23 via this roller 21 down hangs. Each chain 23 is further fixed at its lower end at 25 at the top of the associated guide rail 17.

Wie der Figur 1 zu entnehmen ist, erstrecken sich sämtliche Ketten 23 jeder Hub- oder Verstelleinrichtung 18 jeweils gleichsinnig über die ihrem Befestigungspunkt 24 benachbarte Rolle 21, und zwar bei der für die Figur 1 gewählten Darstellung ausgehend von dem oberen Befestigungspunkt 24 im Gegenuhrzeigersinn um etwa einen Viertel Umfang der zugehörigen Rolle 21. Weiterhin ist die Anordnung so getroffen, daß in der einen Endstellung des Hubes C, die der untersten Stellung der Führungsschiene 17 entspricht, sich der obere Befestigungspunkt 24 an der Rolle 21 oder in unmittelbarer Nähe dieser Rolle befindet, während in der anderen Extremstellung des Hubes C, die der oberen Stellung der Führungsschiene 17 entspricht, der obere Befestigungspunkt 24 von der zugehörigen Rolle 21 einen größeren Abstand aufweist. In beiden Fällen ist die jeweilige Kette 23 über die zugehörige Rolle 21 geführt.As can be seen from FIG. 1, all the chains 23 of each lifting or adjusting device 18 each extend in the same direction over the roller 21 adjacent to its attachment point 24, in the case of the representation chosen for FIG. 1, starting from the upper attachment point 24 in the counterclockwise direction a fourth circumference of the associated roller 21. Furthermore, the arrangement is such that in the one end position of the stroke C, which corresponds to the lowermost position of the guide rail 17, the upper attachment point 24 is located on the roller 21 or in the immediate vicinity of this role, while in the other Extreme position of the stroke C, which corresponds to the upper position of the guide rail 17, the upper attachment point 24 of the associated roller 21 has a greater distance. In both cases, the respective chain 23 is guided over the associated roller 21.

Die Ausbildung der Hubschiene 19 als C- oder U-Profil und die Befestigung der Ketten 23 im Inneren dieses Profils haben den Vorteil, daß die Hubschiene 19 auf den Rollen 21 aufliegt und über die gleichen Rollen 21 auch die Ketten 23 geführt sind. Anstelle des C-Profils kann für die Hubschienen 19 auch ein anderes Profil, beispielsweise ein Vollprofil oder ein Rohrprofil mit quadratischem oder rechteckförmigem Querschnitt verwendet sein, wobei dieses Profil dann jeweils im Bereich der Rollen 21 mit einer zur Unterseite hin offenen Ausnehmung für die Ketten 23 derart versehen ist, daß im Bereich der Ausnehmung ein U- oder C-förmiger Querschnitt erhalten ist. Weiterhin ist es möglich, die Rollen 21 jeweils mit einer Umfangsnut für die Ketten 23 zu versehen, wobei die jeweilige Hubschiene dann seitlich von dieser Nut auf der Rolle aufliegt.The design of the lifting rail 19 as a C or U-profile and the attachment of the chains 23 in the interior of this profile have the advantage that the lifting rail 19 rests on the rollers 21 and the chains 23 are guided over the same rollers 21. Instead of the C-profile can be used for the lifting rails 19 and another profile, for example, a solid profile or a tubular profile with square or rectangular cross-section, which profile then each in the region of the rollers 21 with an open towards the bottom recess for the chains 23rd is provided such that in the region of the recess a U- or C-shaped cross-section is obtained. Furthermore, it is possible to provide the rollers 21 each with a circumferential groove for the chains 23, wherein the respective lifting rail then rests laterally from this groove on the roller.

Über einen Antrieb, beispielsweise über einen Seilzug 26, kann die jeweilige Hubschiene 19 in Richtung des Doppelpfeiles C durch Drehen an einem an der Außenseite des Gehäuses 3 vorgesehenen Einstellrad 27 verschoben und damit die Höhe der zugehörigen Führungsschiene 17 eingestellt werden. Bei der dargestellten Ausführungsform ist für jede Verstellvorrichtungen 18 ein eigenes Einstellrad 27 mit zugehörigem Antrieb bzw. Seilzug 26 vorgesehen. Grundsätzlich besteht aber auch die Möglichkeit, sämtliche Verstellvorrichtungen 18 über ein gemeinsames Stellglied, beispielsweise Einstellrad 27, zu betätigen. Selbstverständlich kann diese Einstellung auch motorisch, beispielsweise durch einen Elektromotor oder ein anderes motorisches Stellglied oder Antrieb erfolgen.Via a drive, for example via a cable 26, the respective lifting rail 19 can be moved in the direction of the double arrow C by turning on a provided on the outside of the housing 3 dial 27 and thus the height of the associated guide rail 17 can be adjusted. In the illustrated embodiment, a separate dial 27 is provided with associated drive or cable 26 for each adjustment 18. In principle, however, it is also possible to actuate all adjustment devices 18 via a common actuator, for example dial 27. Of course, this setting can also be done by motor, for example by an electric motor or another motor actuator or drive.

Die Führungsschienen 17 liegen bei der dargestellten Ausführungsform dann, wenn die Kästen 2 bzw. 2a gegen diese Führungsschienen zur Anlage kommen, mit ihrem Massengewicht gegen die Kästen an und bestehen bei der dargestellten Ausführungsform aus einem am Umfang geschlossenen Hohl- oder Rohrprofil mit quadratischem Querschnitt.The guide rails 17 are in the illustrated embodiment, when the boxes 2 and 2a come to rest against these guide rails, with their mass weight against the boxes and consist in the illustrated Embodiment of a closed at the circumference hollow or tubular profile with square cross-section.

Zumindest an dem bezogen auf die Förderrichtung A vorderen Ende ist an jeder Führungsschiene 17 eine kürzere Führungsschiene 17a mit einem Ende angelenkt (Gelenk 28) und mit dem anderen Ende gelenkig (Gelenk 29) mit einem an dem Gehäuse 3 bzw. an einem dortigen Rahmenteil 20 vorgesehenen Lager 30 verbunden, und zwar derart, daß die Längserstreckung der Führungsschiene 17a der gemeinsamen Mittelebene M mit der Längserstreckung der zugehörigen Führungsschiene 17 liegt.At least at the front end relative to the conveying direction A, a shorter guide rail 17a is articulated at each guide rail 17 with one end (joint 28) and hinged at the other end (joint 29) with one on the housing 3 or on a frame part 20 there provided bearing 30, in such a way that the longitudinal extent of the guide rail 17a of the common center plane M with the longitudinal extent of the associated guide rail 17 is located.

Das Gelenk 28 ist so ausgebildet, daß es ein Schwenken zwischen den Führungsschienen 17 und 17a um eine Achse senkrecht zur Mittelebene M ermöglicht. Das am Lager 30 gebildete Gelenk 29 ist so ausgebildet, daß es ein Schwenken um eine senkrecht zur Mittelebene M liegende Achse sowie gleichzeitig auch ein radiales Verschieben in horizontaler Richtung ermöglicht. Bei der dargestellten Ausführungsform ist das Gelenk 29 ein Stift-Schlitz-Gelenk.The hinge 28 is formed so as to allow pivoting between the guide rails 17 and 17a about an axis perpendicular to the median plane M. The hinge 29 formed on the bearing 30 is formed so that it allows pivoting about an axis perpendicular to the median plane M axis and at the same time also a radial displacement in the horizontal direction. In the illustrated embodiment, the hinge 29 is a pin-and-slot joint.

Durch die Führungsschienen 17a wird zum einen verhindert, daß Flaschenkästen 2 bzw. 2a sich am Anfang der jeweiligen Führungsschiene 17 durch eventuelles Anlaufen gegen das dortige Ende dieser Führungsschiene sperren könnten, d.h. durch die Führungsschienen 17a werden die in die jeweilige Förderstrecke 9, 10 bzw. 11 einlaufenden Kästen 2 bzw. 2a also zuverlässig unter die zugehörige Führungsschiene 17 geleitet. Gleichzeitig wird durch die Führungsschienen 17a auch eine Stabilisierung der zugehörigen Führungsschiene 17 erreicht, insbesondere auch gegen ein unerwünschtes Pendeln um eine Achse parallel zur Förderrichtung A. Durch die Gelenke 28 und 29 ist trotz der jeweiligen Führungsschiene 17a eine Höhenverstellung der Führungsschiene 17 in der vorbeschriebenen Weise möglich. Auch die Führungsschienen 17a bestehen jeweils aus einem Rohrprofil mit quadratischem Querschnitt.By the guide rails 17a is prevented on the one hand that bottle crates 2 or 2a could lock at the beginning of the respective guide rail 17 by possibly starting against the local end of this guide rail, ie by the guide rails 17a in the respective conveyor section 9, 10 and 11 incoming boxes 2 and 2a so reliably guided under the associated guide rail 17. At the same time stabilization of the associated guide rail 17 is achieved by the guide rails 17a, in particular against unwanted oscillation about an axis parallel to the conveying direction A. By the joints 28 and 29, despite the respective guide rail 17a, a height adjustment of the guide rail 17 in the manner described above possible. The guide rails 17a each consist of a tube profile with a square cross-section.

Wie die Figur 1 zeigt, werden die Kästen 2, 2a, die eine sehr unterschiedliche Höhe aufweisen können, von der Transportstrecke 10 an den anschließenden Aufwärtsförderer 15 in einer Positionierung übergeben, die der Positionierung dieser Kästen auf der Transportstrecke 10 entspricht, d.h. die Kästen sind mit ihrer offenen Seite im Bereich des Aufwärtsförderers 15 außen liegend mit einem radialen Abstand von der Mittelachse 31 der halbkreisförmigen Bewegungsbahn dieses Aufwärtsförderers angeordnet, der (radiale Abstand) dem Abstand entspricht, den die Transport- oder Förderebene der Transportstrecke 10 von dieser Mittelachse 31 aufweist. Die Transport- oder Förderebene der darüber liegenden Transportstrecke 11 besitzt aber einen wesentlich kleineren Abstand von der Mittelachse 31, wobei die Differenz dieser Abstände etwas größer ist als die größte Höhe der zu verarbeitenden Kästen.As shown in FIG. 1, the boxes 2, 2a, which may have a very different height, are transferred from the transport path 10 to the adjoining upward conveyor 15 in a positioning corresponding to the positioning of these boxes on the transport path 10, i. the boxes are arranged with their open side in the region of the upward conveyor 15 outboard with a radial distance from the central axis 31 of the semicircular trajectory of this upward conveyor which corresponds (radial distance) the distance that the transport or conveying plane of the transport path 10 from this central axis 31 has. However, the transport or conveying level of the overlying transport section 11 has a much smaller distance from the central axis 31, wherein the difference of these distances is slightly larger than the maximum height of the boxes to be processed.

Um nicht nur die Kästen 2 größerer Höhe, sondern auch die Kästen 2a kleinerer Höhe schonend und geräuscharm verarbeiten zu können, ist an dem Übergang zwischen dem Aufwärtsförderer 15 und der Transportstrecke 11 eine einstellbare Kastenführung 32 vorgesehen, über die die Kästen 2 bzw. 2a mit ihrer Unterseite gleitend auf das Förderband bzw. auf die Scharnierbandkette 12 der Transportstrecke 11 gelangen und über die somit eine schonende und insbesondere auch geräuscharme Übergabe von Kästen kleinerer Höhe, beispielsweise der Kästen 2a, erreicht wird.In order to handle not only the boxes 2 greater height, but also the boxes 2a smaller height gently and quietly, an adjustable box guide 32 is provided at the transition between the upward conveyor 15 and the transport section 11 through which the boxes 2 and 2a with sliding on its underside onto the conveyor belt or onto the hinge belt 12 of the transport path 11 and via which a gentle and, in particular, low-noise transfer of boxes of smaller height, for example the boxes 2 a, is achieved.

Am Übergang zwischen dem Aufwärtsförderer 14 und der Transportstrecke 10 ist bei der dargestellten Ausführungsform eine deratige Kastenführung 32 nicht erforderlich, da davon ausgegangen wird, daß die Kästen 2 oder 2a beim Hindurchbewegen durch die als Tauchbad ausgebildete Transportstrecke 9 in der dortigen Reinigungsflüssigkeit aufschwimmen und über die dortige Führungsschiene 17 mit ihrer offenen Oberseite auf einem Niveau gehalten werden, dessen Abstand von der Mittelachse 31 des Aufwärtsförderers 14 gleich oder etwa gleich demjenigen Abstand ist, den die Transportebene der Transportstrecke 10 von dieser Mittelachse 31 aufweist. Grundsätzlich besteht aber die Möglichkeit, auch am Übergang zwischen dem Aufwärtsförderer 14 und der Transportstrecke 10 eine derartige Kastenführung 32 vorzusehen.At the transition between the upward conveyor 14 and the transport path 10 a deratige box guide 32 is not required in the illustrated embodiment, since it is assumed that the boxes 2 or 2a when passing through the formed as a dip bath transport path 9 in the local cleaning liquid and float over the local guide rail 17 are held with its open top at a level whose distance from the central axis 31 of the upward conveyor 14 is equal to or approximately equal to the distance that the transport plane of the transport path 10 from this central axis 31 has. Basically, there is the possibility, even at the transition between the Upward conveyor 14 and the transport path 10 to provide such a box guide 32.

Die Kastenführung 32 besteht im wesentlichen aus zwei von jeweils einem Rohrprofil gebildeten Gleitschiene 33, die jeweils an einem Ende mittels eines Gelenks 34 an einen Rahmen 35 der Transportstrecke 11 angelenkt sind, und zwar schwenkbar um eine horizontale Achse senkrecht zur Mittelebene M bzw. zur Transportrichtung A. Der Rahmen 35 bildet die Führung für die Scharnierbandkette 12 sowie die Lagerung für die Führungs- und Umlenkräder dieser Kette.The box guide 32 consists essentially of two sliding rails 33 each formed by a tubular profile, which are articulated at one end by means of a joint 34 to a frame 35 of the transport path 11, namely pivotable about a horizontal axis perpendicular to the center plane M and to the transport direction A. The frame 35 forms the guide for the hinge band 12 and the storage for the guide and deflection wheels of this chain.

Die Gelenke 34 der beiden Gleitschienen 33 sind achsgleich angeordnet. Mit ihren freien, gebogenen Enden reichen die Gleitschienen 33 in den Aufwärtsförderer 15 hinein. Die Gleitschienen 33 sind beidseitig von der Scharnierbandkette 12 vorgesehen. Etwa in der Mitte sind die beiden Gleitschienen 33 an der Unterseite über einen Quersteg 36 verbunden, der mit seiner Längserstreckung parallel zur Achse der Gelenke 34 liegt. An den Enden des Quersteges 36 ist jeweils mittels eines Gelenks 37 ein Hebel 38 mit einem Ende angelenkt, dessen anderes Ende mittels eines Gelenks 39 an einem Arm 40' eines Winkelhebels 40 angelenkt ist. Der Winkelhebel 40 ist mittels eines Gelenkes 41 an einem Rahmenteil 20 des Gehäuses 3 angelenkt. Das freie Ende des anderen Armes 40" des Winkelhebels 40 ist über ein Zugglied 42 mit der Hubschiene 19 derjenigen Verstellvorrichtung 18 verbunden, mit der die Höhenverstellung der Führungsschiene 17 der darunter liegenden Transportstrecke 10 erfolgt.The joints 34 of the two slides 33 are arranged coaxially. With their free, curved ends, the slide rails 33 extend into the upward conveyor 15. The slide rails 33 are provided on both sides of the hinge belt 12. Approximately in the middle of the two slide rails 33 are connected at the bottom via a transverse web 36, which is parallel to the axis of the joints 34 with its longitudinal extent. At the ends of the cross bar 36, a lever 38 is articulated by means of a joint 37 with one end, the other end is articulated by means of a hinge 39 to an arm 40 'of an angle lever 40. The angle lever 40 is articulated by means of a hinge 41 on a frame part 20 of the housing 3. The free end of the other arm 40 "of the angle lever 40 is connected via a tension member 42 with the lifting rail 19 of that adjusting device 18, with which the height adjustment of the guide rail 17 of the underlying transport path 10 takes place.

Der Hebel 38 sowie die Arme 40' und 42" des Winkelhebels 40 liegen in einer Ebene parallel zur Mittelebene M. Die Gelenke 37, 39 und 41 liegen mit ihren Gelenkachsen senkrecht zu dieser Mittelebene. Die Anordnung ist weiterhin so getroffen, daß beim Verstellen der Hubschiene 19 für die Führungsschiene 17 der Transportstrecke 10 im Sinne eines Absenkens dieser Führungsschiene 17 die beiden Gleitschienen 33 um die Gelenke 34 mit ihren freien Enden nach oben geschwenkt werden bzw. bei einem Anheben der angesprochenen Führungsschiene 17 ein Schwenken der Gleitschienen 33 nach unten erfolgt. Hiermit wird also in Abhängigkeit von der Einstellung der Führungsschiene 17 der dem Aufwärtsförderer 15 vorausgehenden Transportstrecke 10 die am Ausgang des Aufwärtsförderers 15 vorgesehene Kastenführung 32 selbsttätig richtig auf die Höhe der Kästen 2 bzw. 2a derart eingestellt, daß der Abstand der freien Enden der Gleitschienen 33 von der Mittelachse 31 etwa gleich oder geringfügig größer ist als der Abstand der mit verstellten Führungsschiene 17 der Transprtstrecke 10 von der zugehörigen Transportebene TE und somit die innerhalb des Aufwärtsförderers 15 noch gehaltenen Kästen vor der Übergabe an die Transportstrecke 11 mit ihrem Boden auf die gekrümmten Enden der Gleitschienen 33 aufgleiten und dann entlang dieser Gleitschienen 33 schonend und nahezu geräuschlos auf die Transportstrecke 11 gelangen.The lever 38 and the arms 40 'and 42 "of the angle lever 40 lie in a plane parallel to the median plane M. The joints 37, 39 and 41 lie with their axes of articulation perpendicular to this median plane Lifting rail 19 for the guide rail 17 of the transport path 10 in the sense of lowering this guide rail 17, the two slides 33 are pivoted about the joints 34 with their free ends up or at a lifting of the aforementioned guide rail 17 pivoting of the slide rails 33 down. Thus, depending on the setting of the guide rail 17 of the upward conveyor 15 preceding transport path 10 provided at the output of the upward conveyor 15 box guide 32 automatically adjusted properly to the height of the boxes 2 and 2a such that the distance between the free ends of the slide rails 33rd from the central axis 31 is approximately equal to or slightly larger than the distance with the displaced guide rail 17 of the Transprtstrecke 10 of the associated transport plane TE and thus within the upward conveyor 15 still held boxes before transfer to the transport section 11 with its bottom on the curved ends slide on the slide rails 33 and then gently and almost noiseless along the slide rails 33 reach the transport route 11.

Die Einstellung der Kastenführung 32 erfolgt also über das gemeinsame Einstellelement für die Höheneinstellung der Führungsschiene 17 der Kastenführung 32 in Transportrichtung A vorausgehenden Transportstrecke 10.The setting of the box guide 32 thus takes place via the common adjusting element for the height adjustment of the guide rail 17 of the box guide 32 in the transport direction A preceding transport path 10th

Um Kästen 2 bzw. 2a verarbeiten zu können, die in horizontaler Richtung und quer zur Förderrichtung A unterschiedliche Breite aufweisen, ist es üblich und bekannt, die Förderbreite der Aufwärtsförderer 14 bzw. 15 einzustellen, und zwar jeweils durch Verstellen der beiden Rahmenteile 43 des jeweiligen Aufwärtsförderers senkrecht und symmetrisch zur Mittelebene M. An den Rahmenteilen 43 sind die die Klemmbacken bildenden Transportbänder 44 geführt. Diese Verstellung erfolgt über Spindeln 45, die über einen gemeinsamen Antrieb betätigbar sind, beispielsweise über einen manuellen Antrieb an der Außenseite des Gehäuses 3. Um beim Verstellen der Förderbreite der Aufwärtsförderer 14 und 15 zugleich auch eine Breitenverstellung zumindest der Transportstrecken 10 und 11 bzw. der dortigen Führungsgeländer 13 zu erreichen, ist jedes Führungsgeländer 13 beidendig über eine Hebelanordnung 46 mit einem Rahmenelement 43 antriebsmäßig verbunden.In order to process boxes 2 and 2a, which have different width in the horizontal direction and transverse to the conveying direction A, it is common and known to adjust the conveying width of the upward conveyor 14 and 15, respectively by adjusting the two frame parts 43 of the respective Upward conveyor perpendicular and symmetrical to the median plane M. At the frame members 43 which form the jaws conveyor belts 44 are guided. This adjustment takes place via spindles 45 which can be actuated via a common drive, for example via a manual drive on the outside of the housing 3. To adjust the width of the conveyor belt width of the upward conveyor 14 and 15 at the same time a width adjustment of at least the transport routes 10 and 11 and To reach there guide railing 13, each guide railing 13 is connected at both ends via a lever assembly 46 to a frame member 43 drivingly connected.

Die Hebelanordnung 46 besteht aus einem Hebel 47, der über die der jeweiligen Transportstrecke 10 bzw. 11 abgewandte Außenseite des Führungsgeländers 13 schräg wegsteht und an einem Ende mittels eines Gelenkes 48 am Führungsgeländer und am anderen Ende mittels eines Gelenks 49 an einem Rahmenteil 20 des Gehäuses 3 angelenkt ist. In der Mitte ist der Hebel 47 über ein Gelenk 50 mit einem Ende eines Steuerhebels 51 verbunden, dessen anderes Ende über ein Gelenk 52 mit dem Rahmenteil 43 gelenkig verbunden ist. Die Gelenkachsen der Gelenke 48, 49, 50 und 52 sind jeweils vertikale Achsen. Bei der Verstellung der Förderbreite der Aufwärtsförderer 14 bzw. 15 (Doppelpfeil D) wird über den Steuerhebel 51 der zugehörige Hebel 47 für eine Breitenverstellung des seitlichen Führungsgeländers 13 geschwenkt. Über mehrere, dem Hebel 47 entsprechende Hebel 47a ist das Führungsgeländer 13 zwischen seinen beiden Enden im Gehäuse 3 abgestützt.The lever assembly 46 consists of a lever 47 which obliquely via the respective transport path 10 and 11 facing away from the outside of the guide railing 13 protrudes and is articulated at one end by means of a hinge 48 on the guide railing and at the other end by means of a hinge 49 on a frame part 20 of the housing 3. In the middle of the lever 47 is connected via a hinge 50 with one end of a control lever 51, the other end via a hinge 52 to the frame part 43 is pivotally connected. The hinge axes of the joints 48, 49, 50 and 52 are each vertical axes.
