Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen von Behältern, insbesondere von Behältern für gefährliche Flüssigkeiten, in der die Behälter mit nach unten gekehrter Ausgußöffnung von endlosen in ihren Umkehrpunkten um horizontale Achsen umlaufenden Kettenbändern taktweise an den in gleichen Abständen hintereinanderliegenden Behandlungsstationen gefördert werden.The invention relates to a device for cleaning containers, in particular containers for dangerous liquids, in which the containers with the pouring opening turned down are conveyed intermittently from endless chain belts revolving in their reversal points around horizontal axes at the treatment stations located one behind the other at equal intervals.

Bekannte derartige Vorrichtungen dienen in den meisten Anwendungsformen zum Reinigen und auch zum Wiederfüllen von Büchsen, Flaschen oder kleineren Fässern für den Bedarf der Genuß- und Nahrungsmittelindustrie, die von verhältnismäßig leicht löslichen Inhaltsresten gereinigt werden sollen. Eine der eingangs genannten Vorrichtungen, beschrieben in DE A 38 24 379, ist für die Reinigung von kleineren flaschenartigen Behältern oder kleineren Fässern bestimmt. Bei ihr werden diese Behältnisse zunächst in mehreren Reinigungsstationen über Reinigungsköpfen unter Anheben vom Kettenband gespült und nach Durchgang durch eine Wartestation wieder von Füllköpfen gefüllt, wobei die Düsenköpfe auf die Armatur der Behälter passende Masken aufweisen.Known devices of this type are used in most forms of application for cleaning and also for refilling cans, bottles or smaller barrels for the needs of the food and beverage industry, which are relatively easily soluble Residual content should be cleaned. One of the devices mentioned at the outset, described in DE A 38 24 379, is intended for cleaning smaller bottle-like containers or smaller drums. In this case, these containers are first rinsed in several cleaning stations via cleaning heads while lifting them from the chain belt and, after passing through a waiting station, are filled again with filling heads, the nozzle heads having masks that match the fitting of the containers.

Mit keiner der bekannten Reinigungsvorrichtungen lassen sich die aus Kunststoff bestehenden stapelbaren Behälter für gefährliche Flüssigkeiten so reinigen, daß die gereinigten Behälter den geltenden und zu erwartenden Sicherheitsbedingungen und Vorschriften genügen. Die im Verkehr befindlichen Behälter für gefährliche Flüssigkeiten sind in vielen Fällen infolge ihrer Formgebung schwer oder nicht restlos entleerbar oder ihre Entleerung erfolgt nicht mit der notwendigen Sorgfalt. Es muß daher vor der Reinigung der Innenwände für eine vollständige und sichere Restentleerung gesorgt werden, wobei die erhaltenen Flüssigkeitsreste mit Sicherheit aufgefangen und entsorgt werden müssen. Ebenso muß die Reinigungsflüssigkeit vollständig entfernt werden, bevor der Behälter mit Luft ausgetrocknet wird.None of the known cleaning devices can be used to clean the stackable containers for dangerous liquids, which are made of plastic, in such a way that the cleaned containers meet the applicable and expected safety conditions and regulations. In many cases, the containers for dangerous liquids on the market are difficult or impossible to empty due to their shape, or they are not emptied with the necessary care. It is therefore necessary to ensure complete and safe emptying of the residues before cleaning the inner walls, and the liquid residues obtained must be collected and disposed of with certainty. The cleaning liquid must also be completely removed before the container is dried out with air.

Hieraus ergibt sich die der Erfindung gestellte Aufgabe der sicheren Entleerung der Reste der vorher in den Behältern beförderten Flüssigkeit und der vollständigen Reinigung auch schwer zugänglicher Innenbereiche sowie der vollständigen Entleerung und Austrocknung der benutzten Reinigungsflüssigkeit. Ferner muß die Vorrichtung die ihr von Hand oder automatisch zugeführten Behälter in einfacher Weise aufnehmen und nach ihrer Behandlung wieder abgeben. Die Vorrichtung muß auch auf die verschiedenen Behälterformen und -grössen leicht umstellbar sein sowie einen großen Durchsatz je Zeit ermöglichen.This results in the object of the invention of safely emptying the remnants of the liquid previously transported in the containers and the complete one Cleaning even hard-to-reach interior areas as well as the complete emptying and drying out of the cleaning liquid used. Furthermore, the device must pick up the containers fed to it manually or automatically and dispense them again after their treatment. The device must also be easily convertible to the different container shapes and sizes and allow a large throughput per time.

Die Aufgaben werden durch die angegebenen Maßnahmen gelöst, wie sie im Patentanspruch 1 und in den von diesem abhängigen Patentansprüchen gekennzeichnet sind.The tasks are solved by the specified measures, as they are characterized in claim 1 and in the dependent claims.

Die in Figur 1 dargestellte Vorrichtung weist ein langgestrecktes etwa 1,5 m hohes Gestell 1 auf, an dessen Enden je zwei horizontale Achsen 2 mit Kettenrädern 3 vorgesehen sind, auf denen ein endloses Kettenband 4 für den Transport der zu reinigenden Behälter 5 umläuft. Dieses Kettenband 4 besteht aus zwei seitlich angeordneten, auf den Kettenrädern 3 laufenden Gliederketten 6, die in Abständen von in etwa der üblichen Breite der Behälter 5 mit Querstäben 7 untereinander verbunden sind. Auf diesen Querstäben 7 sind Masken 8 für die Aufnahme der Behälter 5 angeordnet, die an die Form des Oberteils der Behälter 5 anpaßbar oder nach der Bauform der zur Reinigung anfallenden Behälter 5 auswechselbar sind und einen Durchbruch für die Ausgußöffnung 9 der Behälter 5 aufweisen.The device shown in Figure 1 has an elongated frame about 1.5 m high, at the ends of which two horizontal axes 2 are provided with sprockets 3, on which an endless chain belt 4 rotates for the transport of the containers 5 to be cleaned. This chain belt 4 consists of two laterally arranged link chains 6 running on the chain wheels 3, which are connected to one another at intervals of approximately the usual width of the containers 5 with cross bars 7. On these cross bars 7 there are masks 8 for accommodating the containers 5, which can be adapted to the shape of the upper part of the containers 5 or can be exchanged according to the design of the containers 5 resulting for cleaning and have an opening for the pouring opening 9 of the containers 5.

Die Behälter für gefährliche Flüssigkeiten haben üblicherweise eine Quaderform mit abgerundeten Ecken und Kanten meist rechteckiger Draufsicht. Die Ausgußöffnung 9 muß, um eine vollständige Entleerung des Behälters 5 zu ermöglichen, in der Mitte der Oberkante einer der Behälterschmalseiten 10 vorgesehen sein.The containers for dangerous liquids usually have a cuboid shape with rounded corners and edges, usually a rectangular plan view. The pouring opening 9 must be provided in the middle of the upper edge of one of the narrow sides of the container 10 in order to enable complete emptying of the container 5.

Die Masken 8 sind so ausgestaltet, daß der aufgesetzte Behälter 5 mit seiner größeren Breitseite 11 quer zum Kettenband 4 und dessen Förderrichtung und zudem schräg mit seiner die Ausgußöffnung 9 aufweisenden Kante nach unten gestellt ist, um ein Auslaufen und Abtropfen der im Behälter 5 noch enthaltenen Rest- bzw. Reinigungsflüssigkeit zu ermöglichen.The masks 8 are designed in such a way that the attached container 5 with its larger broad side 11 is positioned transversely to the chain belt 4 and its conveying direction and also obliquely with its edge having the pouring opening 9 downwards, in order to allow the contained in the container 5 to leak and drip To enable residual or cleaning liquid.

Die Quer- und Schrägstellung der Behälter 5 ermöglicht zudem einen langen Hubweg von Düsenköpfen 12, 13, die von einer Lanze 14 von einem Arbeitszylinder 15 schräg von unten und von der Außenseite des Gestells 1 in die Ausgußöffnung 9 des Behälters 5 eingefahren werden können.The transverse and inclined position of the container 5 also enables a long stroke of nozzle heads 12, 13, which can be inserted obliquely from below by a lance 14 from a working cylinder 15 and from the outside of the frame 1 into the pouring opening 9 of the container 5.

Wie Figur 2 dies zeigt, sind die Masken 8 an ihrer in Laufrichtung vorderen Seite an einem Querstab 7 des Kettenbandes 4 angelenkt und sie sind an ihrer Rückseite an dem nachfolgenden Querstab mit Langlöchern befestigt, um die Bewegung beim Umlauf um die Kettenräder 3 und die dabei eintretende Verkürzung der Abstände der Querstäbe 7 auszugleichen. Die Maske 8 liegt auf der für die Ausgußöffnung 9 des Behälters 5 bestimmten Seite parallel zu der Gliederkette 6, der in der Zeichnung linken, auf den beiden sie tragenden Querstäben 7 unmittelbar auf, auf ihrer anderen Seite bei der anderen Gliederkette 6' auf einem Lagerbock 16, wodurch sich die Schrägstellung des Behälters 5 ergibt. Dieser wird durch den Rahmen 17 in der Maske 8 festgehalten. Im Bereich der Ausgußöffnung 9 des Behälters 5 weist die Maske 8 eine Durchbrechung 18 für den Zugang der Düsenköpfe 12, 13 auf. In jeder Bearbeitungsstation kann ein von einem Arbeitszylinder 19 andrückbarer Niederhalter 20 auf dem Boden des Behälters 5 angreifen, der ihn in der Maske 8 festdrückt.As FIG. 2 shows, the masks 8 are articulated on their front side in the direction of travel to a cross bar 7 of the chain belt 4 and they are fastened on the back to the subsequent cross bar with elongated holes in order to ensure the movement during the rotation around the chain wheels 3 and thereby compensate for the shortening of the distances between the cross bars 7. The mask 8 lies on the side intended for the pouring opening 9 of the container 5 parallel to the link chain 6, the one on the left in the drawing, directly on the two cross bars 7 carrying it, on its other side with the other link chain 6 'on a bearing block 16, which results in the inclination of the container 5. This is held in the mask 8 by the frame 17. In the area of the pouring opening 9 of the container 5, the mask 8 has an opening 18 for the access of the nozzle heads 12, 13. In each processing station, a hold-down device 20 that can be pressed by a working cylinder 19 can engage on the bottom of the container 5 and press it down in the mask 8.

Die Behälter 5 werden auf der in Figur 1 linken Seite des Gestells 1 von den sich am Kettenband 4 nach oben drehenden Masken 8 aufgenommen. Sie können dazu entweder von Hand oder automatisch von einem Förderband positioniert werden. Die Behälter 5 durchlaufen zunächst die Abtropfstationen 21 und 22, unter denen sich eine Auffangwanne 23 befindet, in der die sich aus den Behältern 5 entleerende Flüssigkeit gesammelt wird.The containers 5 are on the left in Figure 1 of the frame 1 from the chain belt 4 upwards rotating masks 8 added. They can be positioned either manually or automatically by a conveyor belt. The containers 5 first pass through the draining stations 21 and 22, under which there is a collecting trough 23 in which the liquid emptying from the containers 5 is collected.

Um ein restloses Entleeren von Flüssigkeiten höherer Viskosität zu erreichen, kann in der letzten Abtropfstation 22 eine Schwenk- und Rüttelvorrichtung vorgesehen sein, wie dies Figur 3 darstellt. Dazu muß die Maske 8' auf der in der Zeichnung zu Figur 3 linken Seite entlang der Gliederkette 6 in einem Gelenk 24 nach oben schwenkbar sein und auf dem Lagerbock 16 lose aufliegen. Auf der in der Zeichnung rechten Seite ist ein Rüttler 25 vorgesehen. Dieser Rüttler 25 besteht aus einem seitlich am Gestell 1 schräg nach innen gestellten Arbeitszylinder 26, der eine Kolbenstange 27 aus- und einfahren kann, an deren oberen Ende ein Kopf 28 aus elastomerem Material vorgesehen ist. An den Masken 8 ist bei dieser Ausführungsform je ein Arm 29a vorgesehen, an dem der Kopf 28 angreift. Durch entsprechende Steuerung des Arbeitszylinders 26 kann der Behälter 5 entweder um das Gelenk 24 geschwenkt und/oder in einer, der Viskosität der zu entfernenden Restflüssigkeit entsprechenden Frequenz bei kleiner Amplitude gerüttelt werden. Auf der anderen Seite des Gestells 1 ist an einem feststehenden Arm 30 ein elastischer Puffer 31 vorgesehen, gegen den das obere Eck des Behälters 5 anschlägt und der ein Herauskippen des Behälters 5 bei der Schwenkbebewegung verhindert. Die Schwenk- und Rüttelbewegung des Rüttlers 25 erfolgt nicht nur gegen das Gewicht des Behälters 5, sondern vor allem gegen die Wirkung einer Feder 32, die zwischen der Maske 8 und dem Lagerbock 16 gespannt ist. Wenn ein solcher Rüttler 25 vorgesehen ist, müssen alle Masken 8, so wie vorstehend beschrieben, gegen die Kraft der Feder 32 um das Gelenk 24 schwenkbar sein.In order to achieve complete emptying of liquids of higher viscosity, a swiveling and vibrating device can be provided in the last draining station 22, as shown in FIG. 3. For this purpose, the mask 8 'on the left side in the drawing of FIG. 3 must be pivotable upwards in a joint 24 along the link chain 6 and rest loosely on the bearing block 16. A vibrator 25 is provided on the right side in the drawing. This vibrator 25 consists of a laterally on the frame 1 obliquely inward working cylinder 26 which can extend and retract a piston rod 27, at the upper end of which a head 28 is provided made of elastomeric material. In this embodiment, one arm 29a is provided on the masks 8, on which the head 28 engages. By appropriate control of the working cylinder 26, the container 5 can either be pivoted about the joint 24 and / or shaken at a low amplitude corresponding to the viscosity of the residual liquid to be removed. On the other side of the frame 1, an elastic buffer 31 is provided on a fixed arm 30, against which the upper corner of the container 5 strikes and the prevents the container 5 from tipping out during the pivoting movement. The pivoting and shaking movement of the vibrator 25 takes place not only against the weight of the container 5, but above all against the action of a spring 32 which is tensioned between the mask 8 and the bearing block 16. If such a vibrator 25 is provided, all masks 8, as described above, must be pivotable about the joint 24 against the force of the spring 32.

Die auf der Unterseite des Gestells 1 zurückgeführten leeren, nach unten hängenden Masken 8 würden für die Kraft der Feder 32 zu schwer sein und abkippen. Es sind daher an den Enden der Arme 29a Rollen 33 vorgesehen, die auf einer in den Zeichnungen nicht dargestellten Bahn laufen, sobald die Masken 8 auf die Unterseite des Gestells 1 um die in der Figur 1 rechten Kettenräder 3 nach unten geschwenkt werden.The empty, downward hanging masks 8 which are led back to the underside of the frame 1 would be too heavy for the force of the spring 32 and would tip over. There are therefore provided at the ends of the arms 29a rollers 33 which run on a path not shown in the drawings as soon as the masks 8 are pivoted downward on the underside of the frame 1 about the chain wheels 3 on the right in FIG.

Nach der letzten Abtropfstation bzw. der mit der vorstehenden Rüttelvorrichtung versehenen Station 22 gelangen die Behälter 5 in die eigentliche Reinigungsstation 34, in der der Düsenkopf 13 durch ihre Ausgußöffnung 9 in sie eingefahren wird. Der Düsenkopf 13 ist am Ende der Lanze 14 angeordnet, die von dem Arbeitszylinder 15 in die Behälter 5 geschoben und nach Beendigung des Reinigungsvorgangs zurückgezogen wird und durch die Reinigungsflüssigkeit zum Düsenkopf 13 unter Druck zugeführt wird. Der Düsenkopf 13 weist Düsenöffnungen auf, durch die die gesamte Innenwandung Behälter 5 mit der Reinigungsflüssigkeit ausgespritzt wird. An der Lanze 14 ist eine weitere Düsenanordnung 35 vorgesehen, die beim Einfahren der Lanze 14 in den Behälter 5 kurz oberhalb der Ausgußöffnung 9 liegt und schräg nach unten gerichtete Düsenöffnungen aufweist, um die schwer zugänglichen inneren Schulterbereiche beiderseits der Ausgußöffnung 9 des Behälters 5 zu erreichen. Des weiteren ist an der Lanze 14 um diese liegend ein Düsenring 36 vorgesehen, der mit der Zuleitung für die Reinigungsflüssigkeit in der Lanze 14 mit einer Rohrleitung 37 in Verbindung steht und der bei ausgefahrener Lanze 14 außen um den Gewindestutzen 38 der Ausgußöffnung 9 liegt. Mit den nach innen gerichteten Düsen dieses Düsenringes 36 werden die Gewindegänge und der Ansatz des Gewindestutzens 38 besprüht, die von der im Behälter 5 enthalten gewesenen Flüssigkeit beim Verfüllen, Ausgießen und vor allem beim Abtropfen verunreinigt wurden. Um den Düsenring 36 ist eine an der Lanze 14 befestigte Auffangschale 39 vorgesehen, die mit einer Schlauchleitung 40 mit einem Sammelbecken 41 verbunden ist, in das die rückfließende Reinigungsflüssigkeit von einer Pumpe 42 abgezogen wird.After the last draining station or the station 22 provided with the above vibrating device, the containers 5 enter the actual cleaning station 34, in which the nozzle head 13 is inserted into it through its pouring opening 9. The nozzle head 13 is arranged at the end of the lance 14, which is pushed into the container 5 by the working cylinder 15 and withdrawn after the cleaning process has ended and is supplied to the nozzle head 13 under pressure by the cleaning liquid. The nozzle head 13 has nozzle openings through which the entire inner wall of the container 5 with the cleaning liquid is sprayed out. A further nozzle arrangement 35 is provided on the lance 14, which is located just above the pouring opening 9 when the lance 14 moves into the container 5 and has obliquely downwardly directed nozzle openings in order to reach the difficult to access inner shoulder areas on both sides of the pouring opening 9 of the container 5 . Furthermore, a nozzle ring 36 is provided on the lance 14, which is connected to the supply line for the cleaning liquid in the lance 14 with a pipeline 37 and which, when the lance 14 is extended, lies outside around the threaded connector 38 of the pouring opening 9. With the inwardly directed nozzles of this nozzle ring 36, the threads and the attachment of the threaded connector 38 are sprayed, which were contaminated by the liquid contained in the container 5 during the filling, pouring and especially when dripping. Around the nozzle ring 36, a collecting bowl 39 is provided which is attached to the lance 14 and which is connected by a hose line 40 to a collecting basin 41 into which the cleaning liquid flowing back is drawn off by a pump 42.

In dieser Station 34 ist es vor allem notwendig, den Behälter 5 gegen den Druck des Aussprühens mit Reinigungsflüssigkeit in der Maske 8 durch Niederhalter 20 festzuhalten, der an einer am Gestell 1 feststehenden Stange 43 höhenverschiebbar befestigt ist.In this station 34, it is above all necessary to hold the container 5 against the pressure of spraying with cleaning liquid in the mask 8 by holding-down device 20, which is fastened in a height-displaceable manner on a rod 43 fixed to the frame 1.

Nach der Reinigungsstation 34 folgt wieder eine Abtropfstation 44, die ebenfalls mit einem Rüttler 25 versehen sein kann wie die Station 22. Die Reste der Reinigungsflüssigkeit werden in eine Sammelwanne 45 entleert, die wiederum mit dem Sammelbehälter 41 über ein Rohr 46 in Verbindung steht.After the cleaning station 34 there is again a draining station 44, which can also be provided with a vibrator 25 like station 22. The residues of the cleaning liquid are emptied into a collecting trough 45, which in turn is connected to the collecting container 41 via a pipe 46.

Die letzte Station ist die Trocknungsstation 47, in der, wie in der Reinigungsstation, ein Düsenkopf 13 von einer von einem Arbeitszylinder 15 bewegten Lanze 14 in die Ausgußöffnung 9 des Behälters 5 eingefahren werden kann. Durch diese Lanze 14 und die Düsen des Düsenkopfes 13 wird hier heiße Druckluft in den Behälter 5 eingeblasen, wobei wiederum die kritischen Räume der Behälterschultern durch die Düsenanordnung besonders berücksichtigt sind.The last station is the drying station 47, in which, as in the cleaning station, a nozzle head 13 can be inserted into the pouring opening 9 of the container 5 by a lance 14 moved by a working cylinder 15. Through this lance 14 and the nozzles of the nozzle head 13, hot compressed air is blown into the container 5, again the critical spaces of the container shoulders being particularly taken into account by the nozzle arrangement.

An der Lanze 14 der Trocknungsstation 47 ist wie in der Reinigungsstation 34 eine Auffangschale 39 mit einer Schlauchleitung 40 zum Sammelbehälter 41 vorgesehen, um die noch abtropfenden Reste der Reinigungsflüssigkeit abzuführen.On the lance 14 of the drying station 47, as in the cleaning station 34, a collecting bowl 39 with a hose line 40 to the collecting container 41 is provided in order to discharge the residues of the cleaning liquid that are still dripping.

Nach Beendigung der Trocknung werden die Behälter 5 am in der Zeichnung zu Figur 1 rechten Ende des Gestells 1 bei der Abwärtsbewegung des Kettenbandes 4 entweder von Hand abgenommen oder bei Abkippen der Masken 8 auf ein Transportband abgegeben.After drying has ended, the containers 5 are either removed by hand at the right end of the frame 1 in the drawing of FIG. 1 during the downward movement of the chain belt 4 or are released onto a conveyor belt when the masks 8 are tilted.

Die Masken 8 bestehen aus einer Grundplatte 29, auf der der Rahmen 17, der aus in Langlöchern verschiebbaren Teilen 48, 49, 59, 51 besteht, steht. Diese Teile lassen sich an die jeweilige Behälterform einstellen und mit Flügelschrauben 52, 53, 54 sichern.The masks 8 consist of a base plate 29 on which the frame 17, which consists of parts 48, 49, 59, 51 which can be displaced in elongated holes, stands. These parts can be adjusted to the respective container shape and secured with wing screws 52, 53, 54.

Die gesamte Anlage ist in ihren einzelnen Funktionen und Bewegungen elektronisch gesteuert. Das Steuerpult ist in Figur 1 auf der linken Seite des Gestells 1 bei 55 gezeigt.The entire system is electronically controlled in its individual functions and movements. The control panel is shown in Figure 1 on the left side of the frame 1 at 55.
