Description

Die Erfindung betrifft eine Gefäßfüllmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a vessel filling machine according to the preamble of claim 1.

Es ist bereits eine derartige Gefäßfüllmaschine bekannt, bei der die Halterungen mit den eingesetzten Spülkappen sowohl in ihrer Arbeitsposition als auch in ihrer Ruheposition vollständig außerhalb der Schutzwand liegen, die das Eindringen von Scherben, Flüssigkeitsresten usw. ins Innere der Gefäßfüllmaschine verhindert. Die Spülkappen und ihre Halterungen dagegen sind vollkommen ungeschützt und können daher im normalen Füllbetrieb leicht beschädigt und verunreinigt werden. Außerdem behindern diese störenden Anbauten eine Sauberhaltung bzw. Sterilhaltung der Umgebung der Füllorgane, wie es im Sinne einer möglichst keimfreien Abfüllung erstrebenswert ist.Such a vessel filling machine is already known, in which the holders with the rinsing caps used, both in their working position and in their rest position, lie completely outside the protective wall which prevents the penetration of fragments, liquid residues, etc. into the interior of the vessel filling machine. The flushing caps and their holders, on the other hand, are completely unprotected and can therefore easily be damaged and contaminated in normal filling operation. In addition, these disruptive attachments prevent the environment around the filling elements from being kept clean or sterile, as is desirable in the sense of as sterile filling as possible.

Das gleiche gilt für andere bekannte Gefäßfüllmaschinen, bei denen die Spülkappen bzw. deren Halterungen unmittelbar an den Huborganen für die Gefäße angeordnet sind (DE-OS 37 22 495) oder die Spülkappen schwenkbar am umlaufenden Träger für die Füllorgane gelagert sind (DE-OS 28 04 423).The same applies to other known vessel filling machines, in which the flushing caps or their holders are arranged directly on the lifting elements for the vessels (DE-OS 37 22 495) or the flushing caps are pivotably mounted on the rotating carrier for the filling elements (DE-OS 28 04 423).

Der Erfindung liegt die Aufgabe zugrunde, bei einer Gefäßfüllmaschine der eingangs genannten Art mit einfachen Mitteln die in der Ruhestellung befindlichen Halterungen und Spülkappen besser gegen Beschädigungen und Verunreinigungen zu schützen.The invention has for its object to protect the holders and rinsing caps in the rest position better against damage and contamination in a vessel filling machine of the type mentioned with simple means.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Bei einer erfindungsgemäßen Gefäßfüllmaschine liegen somit die Halterungen und die von diesen getragenen Spülkappen in ihrer Ruheposition, wenn sie also nicht benötigt werden, völlig innerhalb der Schutzwand bzw. hinter den Deckeln und können daher durch die im normalen Füllbetrieb unweigerlich anfallenden Scherben, Flüssigkeitsspritzer usw. nicht beaufschlagt werden. Außerdem sind im normalen Füllbetrieb außerhalb der Schutzwand im Bereich der Füllorgane keine unnötigen Anbauten vorhanden, so daß dieser Bereich aufgrund seiner "glatten" Gestalt durch Abspritzen mit Desinfektionsmittel oder dgl. leicht sauber gehalten werden kann.In a vessel filling machine according to the invention, the brackets and the rinsing caps carried by them are therefore completely in the protective wall or behind the lids in their rest position, so when they are not needed, and therefore cannot be broken due to the shards, liquid splashes, etc. that are inevitably produced in normal filling operation be charged. In addition, there are no unnecessary attachments in the area of the filling elements in the normal filling operation outside the protective wall, so that this area can easily be kept clean due to its "smooth" shape by spraying with disinfectant or the like.

Es ist ohne weiteres machbar, für alle Halterungen in der Schutzwand eine einzige Öffnung in Form eines ringartigen Schlitzes anzubringen, die z.B. durch eine heb- und senkbare Ringblende abgedeckt bzw. freigegeben wird. Nach der im Anspruch 2 angegebenen Weiterbildung der Erfindung jedoch ist jedem Füllorgan eine eigene Öffnung mit einem eigenen Deckel zugeordnet. Auf diese Weise ist ein individuelles Öffnen und Schließen möglich und die Schwächung der Schutzwand wird gering gehalten.It is easily feasible to make a single opening in the form of an annular slot for all mounts in the protective wall, which can be raised and lowered, for example Ring aperture is covered or released. According to the development of the invention specified in claim 2, however, each filling element is assigned its own opening with its own cover. In this way, individual opening and closing is possible and the weakening of the protective wall is kept to a minimum.

Die einzelnen Deckel können entweder fluchtend oder überdeckend mit der Schutzwand ausgebildet werden. Entsprechende Weiterbildungen der Erfindung sind in den Ansprüchen 3 und 4 angegeben.The individual lids can either be aligned or overlapping with the protective wall. Corresponding developments of the invention are specified in claims 3 and 4.

Die einzelnen Deckel können z.B. als Klappdeckel ausgebildet sein, die beim Ausfahren der Halterung entgegen einer Federkraft selbsttätig aufgedrückt werden. Nach der im Anspruch 5 angegebenen Weiterbildung der Erfindung jedoch ist jeder Deckel am äußeren Ende seiner Halterung befestigt. Auf diese Weise wird eine eigene Lagerung und Betätigung für die Deckel vermieden.The individual lids can e.g. be designed as a hinged lid, which are automatically pressed against the spring force when the holder is extended. According to the development of the invention specified in claim 5, however, each cover is attached to the outer end of its holder. In this way, a separate storage and actuation for the lid is avoided.

Andere vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen 6 bis 21 angegeben.Other advantageous developments of the invention are specified in subclaims 6 to 21.

Die Gefäßfüllmaschine nach den Fig. 1 bis 3 ist zum Füllen von nicht gezeigten Gefäßen in Form von Glasflaschen mit einem kohlensäurehaltigen Getränk unter Gegendruck eingerichtet. Sie weist einen um eine senkrechte Drehachse 14 umlaufenden ringförmigen Rotor 15 auf, an dessen Unterseite gleichmäßig über den Umfang verteilt mehrere kurvengesteuerte Huborgane 16 für die Gefäße angeordnet sind. Die Huborgane 16 sind nach außen hin teilweise durch einen am Rotor 15 befestigten zylindrischen Schutzmantel 17 abgedeckt.The vessel filling machine according to FIGS. 1 to 3 is set up for filling vessels, not shown, in the form of glass bottles with a carbonated beverage under counterpressure. It has an annular rotor 15 rotating around a vertical axis of rotation 14, on the underside of which a plurality of cam-controlled lifting members 16 for the vessels are arranged, evenly distributed over the circumference. The lifting members 16 are partially covered on the outside by a cylindrical protective jacket 17 attached to the rotor 15.

Auf dem Rotor 15 stützt sich über mehrere senkrechte Schraubspindeln 18 konzentrisch zur Drehachse 14 ein Ringkessel 19 mit mehreren Kammern für Flüssigkeit, Spanngas, Rückgas usw. ab. An der Außenseite des Ringkessels 19 sind gleichmäßig über den Umfang verteilt mehrere Füllorgane 1 befestigt, jeweils eines über jedem Huborgan 16. Die Füllorgane 1 weisen am unteren Ende einen Auslaufstutzen 20 für die Flüssigkeit und ein diesen konzentrisch durchsetzendes Rückgasrohr 21 auf und sind im Inneren mit nicht gezeigten Steuerventilen für Flüssigkeit, Spanngas, Rückgas usw. ausgestattet.On the rotor 15 is supported by a plurality of vertical screw spindles 18 concentrically to the axis of rotation 14, an annular bowl 19 with several chambers for liquid, span gas, return gas, etc. On the outside of the ring bowl 19, a plurality of filling elements 1 are attached, distributed uniformly over the circumference, one each over each lifting element 16. The filling elements 1 have an outlet connection 20 for the liquid at the lower end and a return gas pipe 21 concentrically penetrating them and are inside with Control valves for liquid, span gas, return gas, etc., not shown.

An jedem Füllorgan 1 ist ein Schlitten 11, bestehend aus zwei parallelen Stangen und zwei Querstegen, höhenbeweglich gelagert. Der Schlitten 11 trägt am unteren Ende eine Zentrierglocke 22 und am oberen Ende eine Kurvenrolle 23. Die Kurvenrollen 23 wirken mit einer ortsfesten Steuerkurve 29 zusammen und steuern so die Höhenlage bzw. Höhenbewegung der Schlitten 11 mit ihren Anbauten. Zusätzlich ist an der Oberseite jedes Füllorgans 1 ein winkelförmiger Riegel 13 schwenkbar gelagert, der im normalen Füllbetrieb durch eine Druckfeder 30 außer Eingriff mit dem Schlitten 11 gehalten wird (siehe Fig. 3). Am freien Ende des unteren horizontalen Schenkels des Riegels 13 ist eine weitere Kurvenrolle 32 gelagert, die mit einem ortsfesten Kurvenstück 31 zusammenwirken kann. Dieses steht im normalen Füllbetrieb außerhalb der Umlaufbahn der Kurvenrollen 32. Zu Beginn des Spülbetriebs wird es in die Umlaufbahn der Kurvenrollen 32 eingefahren und drückt entgegen der Kraft der Druckfedern 30 den oberen senkrechten Schenkel der Riegel 13 unter den oberen Quersteg der Schlitten 11, die zuvor durch die Steuerkurve 29 entsprechend angehoben worden sind (siehe Fig. 1, rechte Seite). Der Riegel 13 verbleibt durch Selbsthemmung in dieser Sperrstellung, auch in den Bereichen, in denen die Steuerkurven 29 und 31 unterbrochen sind. Der Kurvenverlauf ist in Fig. 1 strichpunktiert angedeutet; die Umlaufrichtung ist durch einen Pfeil markiert. Durch ein leichtes Anheben des Schlittens 11 über die Steuerkurve 29 wird der Riegel 13 durch die Druckfeder 30 selbsttätig in die in Fig. 3 gezeigte Neutralstellung zurückbewegt und der Schlitten 11 kann durch die Steuerkurve 29 gesteuert abgesenkt werden.On each filling element 1, a slide 11, consisting of two parallel rods and two crosspieces, is mounted so that it can move in height. The carriage 11 carries a centering bell 22 at the lower end and a cam roller 23 at the upper end. The cam rollers 23 cooperate with a fixed control cam 29 and thus control the height or movement of the carriage 11 with its attachments. In addition, an angular bolt 13 is pivotally mounted on the top of each filling element 1, which is kept out of engagement with the slide 11 by a compression spring 30 during normal filling operation (see FIG. 3). At the free end of the lower horizontal leg of the bolt 13, a further cam roller 32 is mounted, which can cooperate with a fixed cam piece 31. This is in normal filling operation outside the orbit of the cam rollers 32. At the beginning of the flushing operation, it is inserted into the orbit of the cam rollers 32 and presses the upper vertical leg of the bolt 13 under the upper crosspiece of the carriage 11, previously, against the force of the compression springs 30 have been raised accordingly by the control curve 29 (see FIG. 1, right side). The bolt 13 remains in this locked position by self-locking, even in the areas in which the control curves 29 and 31 are interrupted. The curve is indicated by dash-dotted lines in FIG. 1; the direction of rotation is marked by an arrow. By slightly lifting the slide 11 above the control curve 29, the bolt 13 is automatically moved back into the neutral position shown in FIG. 3 by the compression spring 30 and the slide 11 can be lowered in a controlled manner by the control curve 29.

An der Unterseite des Ringkessels 19 ist konzentrisch zur Drehachse 14 eine zylindrische Schutzwand 5 aus rostfreiem Stahlblech befestigt. Diese liegt radial innerhalb der Füllorgane 1 und der Schlitten 11 und überdeckt mit ihrem unteren Ende den Schutzmantel 17.On the underside of the ring bowl 19, a cylindrical protective wall 5 made of stainless steel sheet is attached concentrically to the axis of rotation 14. This lies radially inside the filling elements 1 and the slide 11 and covers the protective jacket 17 with its lower end.

An der Innenseite der Schutzwand 5 sind für jedes Füllorgan 1 übereinander zwei radial zur Drehachse 14 verlaufende Stangen 9 befestigt. Auf jedem Paar von Stangen 9 ist eine Halterung 2 verschiebbar gelagert, die durch eine schmale Platte gebildet wird, welche radial zur Drehachse 14 ausgerichtet ist. An jeder Halterung 2 greift ein Antriebsorgan 4 in Form eines doppelt wirkenden Pneumatikzylinders an, der andererseits mit den Stangen 9 verbunden ist. Am radial äußeren Ende jeder Halterung 2 ist ein kreisrunde Aufnahmebohrung 8 ausgebildet, in die eine Spülkappe 3 lose einsteckbar ist.On the inside of the protective wall 5, two rods 9 extending radially to the axis of rotation 14 are fastened one above the other for each filling element 1. On each pair of rods 9, a bracket 2 is slidably mounted, which is formed by a narrow plate which is aligned radially to the axis of rotation 14. On each bracket 2, a drive element 4 acts in the form of a double-acting pneumatic cylinder, which on the other hand is connected to the rods 9. At the radially outer end of each holder 2, a circular receiving bore 8 is formed, into which a flushing cap 3 can be inserted loosely.

Die rotationssymmetrische Spülkappe 3 besitzt am oberen Ende einen verbreiterten Bund 10, mit dem sie an der Oberseite der Halterung 2 aufliegt und so höhenmäßig fixiert ist. Unterhalb des Bundes 10 ist die Spülkappe 3 rohrartig, wobei ihr Außendurchmesser etwas kleiner ist als der Durchmesser der Aufnahmebohrung 8. Das untere Ende der Spülkappe 3 ist geschlossen und außen konisch verjüngt, wodurch das Einstecken in die Aufnahmebohrung 8 erleichtert wird. Die obere Stirnseite jeder Spülkappe 3 im Bereich des Bundes 10 weist einen Dichtring 35 auf und ist derart an die Zentrierglocke 22 angepaßt, daß sie flüssigkeitsdicht an diese anschließbar ist.The rotationally symmetrical flushing cap 3 has a widened collar 10 at the upper end, with which it rests on the top of the holder 2 and is thus fixed in terms of height. Below the collar 10, the flushing cap 3 is tube-like, its outer diameter being somewhat smaller than the diameter of the receiving bore 8. The lower end of the flushing cap 3 is closed and tapered on the outside, which makes it easier to insert into the receiving bore 8. The upper end face of each rinsing cap 3 in the region of the collar 10 has a sealing ring 35 and is adapted to the centering bell 22 in such a way that it can be connected to it in a liquid-tight manner.

Unterhalb jedes Paares von Stangen 9 ist in der Schutzwand 5 eine Öffnung 6 ausgebildet, durch die die zugehörige Halterung 2 mit eingehängter Spülkappe 3 kollisionsfrei hindurch bewegt werden kann. An der radial nach außen weisenden Stirnseite jeder Halterung 2 ist ein flacher Deckel 7 befestigt, der exakt in die Öffnung 6 paßt und diese somit bei entsprechender Lage seiner Halterung 2 fluchtend mit der Schutzwand 5 verschließt. Der Deckel 7 hat eine T-artige Grundform, wobei der horizontale Querschenkel hinsichtlich Länge und Dicke mit dem Bund 10 der Spülkappe 3 übereinstimmt.Below each pair of rods 9, an opening 6 is formed in the protective wall 5, through which the associated holder 2 with the flushing cap 3 attached can be moved through without collision. On the radially outward-facing end face of each holder 2, a flat cover 7 is fastened, which fits exactly into the opening 6 and thus closes it flush with the protective wall 5 when its holder 2 is in the appropriate position. The cover 7 has a T-like basic shape, the horizontal cross leg corresponding in length and thickness to the collar 10 of the flushing cap 3.

Im normalen Füllbetrieb nehmen alle Halterungen 2 mit ihren eingesteckten Spülkappen 3 die in Fig. 3 dargestellte Ruheposition ein. Dabei befinden sich alle Halterungen 2 und alle Spülkappen 3 vollständig innerhalb bzw. hinter der zylindrischen Schutzwand 5, deren Öffnungen 6 durch die Deckel 7 verschlossen sind. Die Halterungen 2 und Spülkappen 3 sind somit gut geschützt gegen die Einwirkung von Scherben, Füllflüssigkeiten, Reinigungsflüssigkeiten usw. Andererseits wird die Hubbewegung der zu füllenden Gefäße mit den Huborganen 16 nicht behindert und es ist der "glatte" Bereich unterhalb der Füllorgane 1 und außerhalb der Schutzwand 5 infolge fehlender Anbauten leicht sauber bzw. steril zu halten.In normal filling operation, all holders 2 with their inserted flushing caps 3 assume the rest position shown in FIG. 3. All holders 2 and all flushing caps 3 are located completely inside or behind the cylindrical protective wall 5, the openings 6 of which are closed by the cover 7. The brackets 2 and rinsing caps 3 are thus well protected against the action of cullet, filling liquids, cleaning liquids, etc. On the other hand, the lifting movement of the vessels to be filled with the lifting members 16 is not hindered and it is the "smooth" area below the filling members 1 and outside of the Protective wall 5 easy to keep clean or sterile due to missing attachments.

Zur Einleitung des Reinigungsbetriebes werden als erstes alle Gefäße aus der Gefäßfüllmaschine entfernt und der Ringkessel 19 wird vollständig entleert. Die nicht gezeigten Elemente für den Gefäßtransport, insbesondere die Transportsterne und Führungsbögen für die Zufuhr und Abfuhr der Gefäße auf bzw. von den Huborganen 16 können an Ort und Stelle verbleiben. Dann werden bei langsam umlaufenden Rotor 15 im Bereich zwischen Auslaufstern und Einlaufstern, wo die Schlitten 11 mit den Zentrierglocken 22 ihre in Fig. 1 auf der linken Seite und in Fig. 3 dargestellte untere Endlage einnehmen, nacheinander alle Halterungen 2 durch Betätigung ihrer Antriebsorgane 4 aus der Ruheposition radial nach außen in die Arbeitsposition bewegt. Dabei geben als erstes die Deckel 7 die Öffnungen 6 frei und die Halterungen 2 mit den Spülkappen 3 durchdringen die Öffnungen 6. Die Arbeitsposition der Halterungen 2 und Spülkappen 3 ist in Fig. 3 strichpunktiert angedeutet und in Fig. 2 dargestellt.To initiate the cleaning operation, all the vessels are first removed from the vessel filling machine and the ring bowl 19 is completely emptied. The elements not shown for the vessel transport, in particular the transport stars and guide sheets for the supply and discharge the vessels on or from the lifting elements 16 can remain in place. Then, with the rotor 15 rotating slowly, in the area between the outlet star and the inlet star, where the carriages 11 with the centering bells 22 assume their lower end position shown in FIG. 1 on the left-hand side and in FIG. 3, all holders 2 are actuated one after the other by actuating their drive elements 4 moved radially outward from the rest position into the working position. First, the covers 7 open the openings 6 and the holders 2 with the flushing caps 3 penetrate the openings 6. The working position of the holders 2 and flushing caps 3 is indicated by dash-dotted lines in FIG. 3 and shown in FIG. 2.

Es ist zu sehen, daß hierbei jede Spülkappe 3 konzentrisch zu ihrer Zentrierglocke 22 liegt und diese, die mit leichtem Spiel im Schlitten 11 gelagert ist, an ihrer Unterseite berührt. Außerdem werden in der Arbeitsposition die Spülkappen 3 durch eine an jedem Schlitten 11 unterhalb der Zentrierglocke 22 ausgebildete Aufnahme 12 in Form zweier Finger gehalten, die an gegenüberliegenden Seiten der Spülkappe 3 an der Unterseite des Bundes 10 angreifen. In der in Fig. 3 gezeigten Position fluchtet die Oberseite der Halterung 2 mit der Oberseite der Aufnahme 12. Wie auch die Fig. 2 deutlich zeigt, ist die Aufnahme 12 nach innen und außen hin offen, so daß die Spülkappen 3 durch die Radialbewegung ihrer Halterung 2 problemlos in die Aufnahme 12 eingefahren und die Deckel 7 vorher zwischen den Fingern der Aufnahme 12 hindurchgefahren werden können. Die Zentrierung der Spülkappen 3 erfolgt zunächst durch ihren rohrartigen Bereich in Verbindung mit der Aufnahmebohrung 8.It can be seen that each rinsing cap 3 is concentric with its centering bell 22 and touches it on its underside, which is supported in the slide 11 with slight play. In addition, the flushing caps 3 are held in the working position by a receptacle 12 in the form of two fingers formed on each slide 11 below the centering bell 22, which engage on opposite sides of the flushing cap 3 on the underside of the collar 10. In the position shown in Fig. 3, the top of the bracket 2 is aligned with the top of the receptacle 12. As also clearly shown in Fig. 2, the receptacle 12 is open inwards and outwards, so that the flushing caps 3 by the radial movement of their Bracket 2 can be easily inserted into the receptacle 12 and the cover 7 can be passed between the fingers of the receptacle 12 beforehand. The flushing caps 3 are first centered by their tubular area in connection with the receiving bore 8.

Im weiteren Verlauf der Umlaufbewegung werden die Schlitten 11 mit den in der Aufnahme 12 hängenden Spülkappen 3 durch die Steuerkurve 29 angehoben und zusammen mit den Zentrierglocken 22 flüssigkeitsdicht an das Füllorgan 1 angepreßt. Dabei werden die Spülkappen 3 anfänglich durch die Aufnahmebohrungen 8 und dann durch die Rückgasrohre 21 seitlich fixiert. Dann werden in der bereits beschriebenen Weise die Riegel 13 durch das Kurvenstück 31 betätigt und die Spülkappen 3 somit ohne Einwirkung der Steuerkurve 29 für eine beliebige Anzahl von Umläufen in der Spülstellung fixiert. Dabei wird in der bei der CIP-Reinigung üblichen Weise das im Kreislauf umgepumpte flüssige Reinigungsmittel durch die Spülkappen 3 vom Auslaufstutzen 20 hin verlustfrei zum Rückgasrohr 21 umgeleitet.In the further course of the orbital movement, the slides 11 with the flushing caps 3 hanging in the receptacle 12 are raised by the control cam 29 and pressed together with the centering bells 22 in a liquid-tight manner against the filling element 1. The purge caps 3 are initially fixed laterally through the receiving bores 8 and then through the return gas tubes 21. Then, in the manner already described, the bolts 13 are actuated by the curve piece 31 and the flushing caps 3 are thus fixed in the flushing position for any number of cycles without the action of the control cam 29. Here, in the manner customary in CIP cleaning, the liquid detergent pumped around in the circuit is diverted through the flushing caps 3 from the outlet nozzle 20 to the return gas pipe 21 without loss.

Am Ende des Reinigungsbetriebes wird das Reinigungsmittel abgelassen und die Schlitten 11 mit den Spülkappen 3 werden in der bereits beschriebenen Weise durch Ausklinken der Riegel 13 wieder abgesenkt. Dabei fädeln sich die verjüngten unteren Enden der von den Aufnahmen 12 getragenen Spülkappen 3 in die Aufnahmebohrungen 8 ein, bis die Spülkappen 3 wieder mit ihrem Bund 10 auf den Halterungen 2 aufliegen. Nunmehr werden durch Betätigung der Antriebsorgane 4 die Halterungen 2 mit den eingesteckten Spülkappen 3 nacheinander zurück in ihre Ruhestellung gefahren. Dabei fährt jede Spülkappe 2 radial nach innen aus ihrer Aufnahme 12 heraus und durch die Öffnung 6 hindurch, bis diese letztlich durch ihren Deckel 7 verschlossen wird, nachdem dieser die Aufnahme 12 passiert hat.At the end of the cleaning operation, the cleaning agent is drained off and the slides 11 with the flushing caps 3 are lowered again in the manner already described by releasing the latches 13. The tapered lower ends of the rinsing caps 3 carried by the receptacles 12 thread into the receiving bores 8 until the rinsing caps 3 rest on the brackets 2 again with their collar 10. Now, by actuating the drive elements 4, the holders 2 with the inserted flushing caps 3 are moved one after the other back into their rest position. Each rinsing cap 2 moves radially inward out of its receptacle 12 and through the opening 6 until it is finally closed by its cover 7 after it has passed the receptacle 12.

Während des Reinigungsbetriebes können die Halterungen 2 in ihrer Arbeitsposition verbleiben oder auch vorübergehend zurück in die Ruheposition verfahren werden. Sowohl Arbeits- als auch Ruheposition werden durch senkrechte Anschlagleisten 33, 34 definiert, die an der Oberseite jeder Halterung 2 befestigt sind und gleichzeitig deren Lagerung auf den Stangen 9 übernehmen. Die Anschlagleisten 33, 34 wirken mit einer Verbindungslasche 25 zwischen dem Antriebsorgan 4 und den Stangen 9 einerseits und mit der Schutzwand 5 andererseits zusammen.During the cleaning operation, the holders 2 can remain in their working position or can also be moved back temporarily into the rest position. Both working and rest position are defined by vertical stop bars 33, 34 which are attached to the top of each bracket 2 and at the same time take over their storage on the rods 9. The stop bars 33, 34 cooperate with a connecting strap 25 between the drive element 4 and the rods 9 on the one hand and with the protective wall 5 on the other hand.

Die Gefäßfüllmaschine nach Fig. 4 und 5 entspricht weitgehend derjenigen nach Fig. 1 bis 3; im Nachstehenden werden nur die Abweichungen beschrieben: Es ist unter jedem Füllorgan 1 an der Innenseite der Schutzwand 5 eine radial und horizontal angeordnete Stange 36 in Form eines nach unten hin offenen C-Profils befestigt. In der Stange 36 ist eine Halterung 37 verschiebbar gelagert, die durch eine längliche Platte aus Kunststoff gebildet wird. An deren radial außen liegendem Ende ist die Aufnahmebohrung 8 für die Spülkappe 3 ausgebildet, die an der Oberseite mit einer Erweiterung zur Aufnahme des Bundes 10 versehen ist. Die Oberseite der Spülkappe 3 fluchtet mit der Oberseite der Halterung 37 und liegt in der Ruheposition dicht unter der geschlossenen Oberseite der Stange 36, die so eine Abdeckung bildet. Auf diese Weise wird das Eindringen von Fremdkörpern usw. ins Innere der in ihrer Ruheposition befindlichen Spülkappe 3 zuverlässig verhindert.The vessel filling machine according to FIGS. 4 and 5 largely corresponds to that according to FIGS. 1 to 3; only the deviations are described below: a radially and horizontally arranged rod 36 in the form of a C-profile which is open at the bottom is fastened under each filling element 1 on the inside of the protective wall 5. In the rod 36, a holder 37 is slidably mounted, which is formed by an elongated plate made of plastic. At its radially outer end, the receiving bore 8 for the flushing cap 3 is formed, which is provided on the top with an extension for receiving the collar 10. The top of the flushing cap 3 is flush with the top of the holder 37 and lies in the rest position just below the closed top of the rod 36, which thus forms a cover. In this way, the penetration of foreign bodies etc. into the interior of the flushing cap 3 which is in its rest position is reliably prevented.

Das Antriebsorgan 4 in Form eines doppelt wirkenden Pneumatikzylinders liegt gleichfalls an geschützter Stelle innerhalb der Halterung 37 bzw. der Stange 36 und ist an einem Ende an der freien Stirnseite der Stange 36 befestigt. Das andere Ende stützt sich über einen Querstift 38 an der Halterung 37 ab.The drive member 4 in the form of a double-acting pneumatic cylinder is also located at a protected location within the holder 37 or the rod 36 and is attached at one end to the free end face of the rod 36. The other end is supported by a cross pin 38 on the bracket 37.

Die Spülkappe 3 ist am unteren Ende mit einer Auslauföffnung 26 versehen, in der ein Ventilkörper 27 verschiebbar gelagert ist. Hängt die Spülkappe 3 frei in ihrer Aufnahme 12, so verschließt der Ventilkörper 27 unter Einfluß seines Eigengewichts die Auslauföffnung 26. Befindet sich dagegen die Spülkappe 3 in ihrer Aufnahmebohrung 8, so wird der Ventilkörper 27 durch ein Steuerorgan 28 in Form eines am unteren Ende des Deckels 7 ausgebildeten horizontalen Schenkels offen gehalten, so daß die Reinigungsflüssigkeit auslaufen kann. Der Deckel 7 ist wiederum an der radial äußeren Stirnseite der Halterung 37 befestigt.The flushing cap 3 is provided at the lower end with an outlet opening 26 in which a valve body 27 is slidably mounted. If the flushing cap 3 hangs freely in its receptacle 12, the valve body 27 closes the outlet opening 26 under the influence of its own weight. On the other hand, if the flushing cap 3 is in its receiving bore 8, the valve body 27 is actuated by a control element 28 in the form of a valve at the lower end of the Cover 7 trained horizontal leg kept open so that the cleaning liquid can leak. The cover 7 is in turn attached to the radially outer end face of the holder 37.

Wie in Fig. 2 angedeutet ist, kann die Schutzwand 5 auch aus einzelnen Segmenten aufgebaut sein und zwischen die Gefäße bzw. Füllorgane eingreifende Trennwände 24 aufweisen. Auch kann die Aufnahme und Anpressung der Spülkappen in der Arbeitsposition durch die Huborgane 16 oder mit den Halterungen verbundene eigene Hubantriebe erfolgen und es können die Spülkappen während der Arbeitsposition in den Halterungen verbleiben.As indicated in FIG. 2, the protective wall 5 can also be constructed from individual segments and can have dividing walls 24 engaging between the vessels or filling elements. The flushing caps can also be picked up and pressed on in the working position by the lifting members 16 or their own lifting drives connected to the holders, and the flushing caps can remain in the holders during the working position.
