Description

Die Erfindung betrifft eine Gefäßverschließmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a vessel closure machine according to the preamble of claim 1.

Es ist bereits eine derartige Gefäßverschließmaschine bekannt, bei der an der Unterseite der Verschließköpfe U-förmige, nach außen hin offene Taschen für die Kronenkorken ausgebildet sind, aus denen die von einem Dauermagneten im Auswerfer gehaltenen Kronenkorken nur geringfügig nach unten überstehen (DE-GM 1 947 169). Die Abstreifeinrichtung weist eine dicht unter den Taschen angeordnete, schräg nach außen verlaufende ortsfeste Kante auf. In den Verschließköpfen hängengebliebene Flaschenreste können durch die schräge Kante ausgeschieden werden. Die Entfernung nicht verarbeiteter Kronenkorken dagegen ist infolge des geringen Überstands äußerst problematisch, so daß Störungen durch doppelt zugeführte oder sich im Bereich der Zuführeinrichtung verhakende Kronenkorken nicht auszuschließen sind.Such a vessel sealing machine is already known in which U-shaped, outwardly open pockets for the crown caps are formed on the underside of the sealing heads, from which the crown caps held by a permanent magnet in the ejector only protrude slightly downwards (DE-GM 1 947 169). The stripping device has a fixed edge which is arranged closely under the pockets and runs obliquely outwards. Bottle remains stuck in the capping heads can be excreted through the sloping edge. The removal of unprocessed crown corks, on the other hand, is extremely problematic due to the small overhang, so that malfunctions caused by crown corks being fed in twice or getting caught in the area of the feed device cannot be ruled out.

Bei einer anderen gattungsgemäßen Gefäßverschließmaschine stehen die wiederum durch einen Dauermagneten im Auswerfer getragenen Kronenkorken mit ihrer vollen Höhe gegenüber der unteren Stirnseite der Verschließköpfe über, so daß nicht verarbeitete Kronenkorken durch eine radial zur Umlaufbahn der Verschließköpfe ausgerichtete ortsfeste Abstreifkante abgenommen und in einen nach unten verlaufenden Abfuhrkanal eingeführt werden können (DE-PS 27 40 440). Ungünstig ist jedoch die ungenügende Fixierung und Mitnahme der Kronenkorken sowohl im Bereich zwischen Zuführeinrichtung und Verschließzone als auch zwischen Verschließzone und Abstreifeinrichtung.In another generic vascular sealing machine, these are in turn by a permanent magnet in the ejector worn crown corks with their full height relative to the lower end face of the closing heads, so that unprocessed crown corks can be removed by a fixed scraping edge oriented radially to the orbit of the closing heads and inserted into a downward-running discharge channel (DE-PS 27 40 440). However, the inadequate fixation and entrainment of the crown caps is disadvantageous both in the area between the feed device and the sealing zone and between the sealing zone and the stripping device.

Der Erfindung liegt die Aufgabe zugrunde, bei einer gattungsgemäßen Gefäßverschließmaschine mit einfachen Mitteln die Wirkung der Abstreifeinrichtung derart zu verbessern, daß auch nicht oder nur geringfügig gegenüber der Unterseite der Verschließköpfe vorstehende, nicht verarbeitete Kronenkorken oder dgl. sicher und störungsfrei von den Verschließköpfen entfernt werden.The invention has for its object to improve the effect of the stripping device in a generic vascular sealing machine with simple means in such a way that unprocessed crown corks or the like which protrude from the underside of the sealing heads or the like are removed safely and without interference from the sealing heads.

Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.

Bei einer erfindungsgemäßen Gefäßverschließmaschine ist kein mechanischer Kontakt zwischen den nicht verarbeiteten Kronenkorken und einer Abstreifkante oder dgl. erforderlich. Die Kronenkorken werden vielmehr durch den oder die Magneten der Abstreifeinrichtung berührungslos entgegen der Kraft der Haltemagneten von den Verschließköpfen wegbewegt. Dies trifft auch dann zu, wenn die Kronenkorken nicht oder nur geringfügig gegenüber der unteren Stirnseite der Verschließköpfe nach unten überstehen.In the case of a vascular sealing machine according to the invention, no mechanical contact between the unprocessed crown caps and a stripping edge or the like is required. Rather, the crown corks are moved away from the closing heads in a contactless manner against the force of the holding magnets by the magnet or magnets of the stripping device. This also applies if the crown corks do not or only slightly protrude downwards relative to the lower end face of the closing heads.

Im einfachsten Fall genügt ein starker Magnet, der mit einem ausreichenden Abstand unterhalb der Bewegungsbahn der Verschließköpfe angeordnet ist, so daß er eine gewisse Anzahl Kronenkorken aufnehmen kann. Er muß dann ab und zu manuell von den angesammelten Kronenkorken befreit werden. Auch ist es denkbar, mehrere auf einer geschlossenen Bahn synchron zu den Verschließköpfen umlaufende Magneten einzusetzen, von denen jeder jeweils einen Kronenkorken von einem Verschließkopf abnehmen kann. Von den umlaufenden Magneten können die Kronenkorken dann mittels eines feststehenden Abstreifers entfernt werden.In the simplest case, a strong magnet, which is arranged at a sufficient distance below the movement path of the closing heads, is sufficient so that it can hold a certain number of crown caps. From time to time, he has to be manually removed from the accumulated crown caps. It is also conceivable to use a plurality of magnets rotating on a closed path synchronously with the closing heads, each of which can remove a crown cap from a closing head. The crown caps can then be removed from the rotating magnets using a fixed scraper.

Besonders zweckmäßig ist es, wenn gemäß den in den Ansprüchen 2 und 3 angegebenen Weiterbildungen der Erfindung die Verschließköpfe selbst für den Transport und die Zentrierung der nicht verarbeiteten Kronenkorken herangezogen werden. Hierdurch wird zum einen ein exakter, störungsfreier Transport der nicht verarbeiteten Kronenkorken vom Verschließbereich zur Abstreifeinrichtung sichergestellt. Zum anderen wird auf einfache Weise die Möglichkeit geschaffen, mittels mehrerer ortsfester Magnete und einer ortsfesten Gleitbahn für einen zuverlässigen Abtransport der abgezogenen Kronenkorken zu sorgen. Entsprechende Weiterbildungen der Erfindung sind in den Ansprüchen 4 bis 14 angegeben.It is particularly expedient if, according to the developments of the invention specified in claims 2 and 3, the closing heads themselves are used for the transport and centering of the unprocessed crown caps. On the one hand, this ensures an exact, trouble-free transport of the unprocessed crown caps from the sealing area to the stripping device. On the other hand, the possibility is created in a simple manner to ensure reliable removal of the removed crown caps by means of a plurality of fixed magnets and a fixed slideway. Corresponding developments of the invention are specified in claims 4 to 14.

Im Nachstehenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen beschrieben. Es zeigen:

In the following an embodiment of the invention will be described with reference to the drawings. Show it:

Die in Fig. 1 und 2 nur teilweise dargestellte Gefäßverschließmaschine ist zum Verschließen von nicht gezeigten Getränkeflaschen mit metallischen, magnetisch beeinflußbaren Kronenkorken 3 eingerichtet. Sie weist einen trommelartigen Rotor 17 mit senkrechter Drehachse auf, an dessen Umfang gleichmäßig verteilt mehrere Verschließköpfe 1 gesteuert höhenbeweglich angeordnet sind. Läuft der Rotor 17 in Richtung des Pfeiles 18 kontinuierlich um, so beschreiben die senkrecht ausgerichteten Verschließköpfe 1 eine kreisförmige Umlaufbahn 19.The vessel closure machine shown only partially in FIGS. 1 and 2 is designed for closing beverage bottles, not shown, with metallic, magnetically influenceable crown caps 3. It has a drum-like rotor 17 with a vertical axis of rotation, on the circumference of which a plurality of closing heads 1 are arranged so as to be vertically movable in a controlled manner. If the rotor 17 rotates continuously in the direction of the arrow 18, the vertically aligned sealing heads 1 describe a circular orbit 19.

Wie die Fig. 2 zeigt, weist jeder Verschließkopf 1 an seiner Unterseite einen rotationssymmetrischen Verschließkonus 20 auf, in dessen Innerem ein zylindrischer Auswerfer 21 gefedert höhenbeweglich gelagert ist. Der Auswerfer 21 ist an seiner unteren, horizontalen Stirnseite mit einem Haltemagneten 2 für einen Kronenkorken 3 versehen. Die untere Stirnseite des Auswerfers 21 liegt in seiner unteren Endposition etwas höher als die untere Stirnseite des Verschließkonus 20 bzw. des Verschließkopfs 1. Hierdurch wird eine Vertiefung 10 gebildet, die den vom Haltemagneten 2 fixierten Kronenkorken 3 vollständig aufnimmt, ohne daß er nach unten übersteht. An der entgegen der Umlaufrichtung der Verschließköpfe 1 weisenden Rückseite jedes Verschließkopfs ist ein nach unten vorstehender, nockenförmiger Mitnehmer 9 ausgebildet. Die Mitnehmer 9 liegen mittig zur Umlaufbahn 19 und sind in ihrer quer zur Umlaufrichtung liegenden Abmessung wesentlich schmäler als ein Kronenkorken 3. Durch die Vertiefungen 10 wird ein exakt zentrierter Korkensitz gewährleistet, während durch die Mitnehmer 9 an jeder beliebigen Stelle der Umlaufbahn 19 ein formschlüssiger, zuverlässiger Transport von Kronenkorken 3 möglich ist.As shown in FIG. 2, each closing head 1 has a rotationally symmetrical closing cone 20 on its underside, in the interior of which a cylindrical ejector 21 is spring-mounted and can be moved in height. The ejector 21 is provided on its lower, horizontal end face with a holding magnet 2 for a crown cap 3. In its lower end position, the lower end face of the ejector 21 is somewhat higher than the lower end face of the closing cone 20 or the closing head 1. This forms a recess 10 which completely receives the crown cork 3 fixed by the holding magnet 2 without it protruding downward . On the back of each capping head pointing counter to the direction of rotation of the capping heads 1 a cam-shaped driver 9 projecting downward is formed. The drivers 9 are located in the center of the orbit 19 and are substantially narrower than a crown cork 3 in their dimensions lying transversely to the direction of rotation. The recesses 10 ensure an exactly centered cork seat, while the drivers 9 provide a positive, at any point in the orbit 19 reliable transport of crown caps 3 is possible.

Die Gefäßverschließmaschine nach Fig. 1 und 2 weist ferner eine Zuführeinrichtung 4 für die Kronenkorken 3 auf, in der die in einer Rutsche 22 angeförderten Kronenkorken mittels nicht dargestellter Transportorgane in einen Fügungskanal 23 bewegt werden, von wo sie durch die Mitnehmer 9 weggerissen und unter Mitwirkung der Haltemagneten 2 in die Vertiefungen 10 eingeführt werden. Die so mit Kronenkorken bestückten Verschließköpfe 1 laufen zur nicht gezeigten Verschließzone, wo durch gesteuertes Absenken der Verschließköpfe 1 die Kronenkorken 3 an die Flaschenmündungen angedrückt und umgebördelt werden. Anschließend laufen die Verschließköpfe 1 im allgemeinen leer zurück zur Zuführeinrichtung 4, wo sie wiederum mit Kronenkorken 3 bestückt werden.1 and 2 also has a feed device 4 for the crown corks 3, in which the crown corks conveyed in a chute 22 are moved into a joining channel 23 by means of transport elements, not shown, from where they are torn away by the drivers 9 and with the cooperation the holding magnet 2 are inserted into the recesses 10. The capping heads 1 thus equipped with crown corks run to the capping zone, not shown, where the crown corks 3 are pressed against the bottle mouths and flanged by controlled lowering of the capping heads 1. Then the closing heads 1 run generally empty back to the feed device 4, where they are again fitted with crown caps 3.

In Umlaufrichtung der Verschließköpfe 1 gesehen unmittelbar vor der Zuführeinrichtung 4 ist eine Abstreifeinrichtung 5 für in der Verschließzone, z.B. infolge Fehlens der entsprechenden Flaschen, nicht verarbeitete und daher zurück in Richtung Zuführeinrichtung 4 laufende Kronenkorken 3 angeordnet. Die Abstreifeinrichtung 5 weist eine horizontale Platte 15 auf, in der auch die Zuführeinrichtung 4 integriert ist und die durch zwei senkrechte Säulen 24 am feststehenden, nicht gezeigten Oberteil der Gefäßverschließmaschine abnehmbar befestigt ist.Viewed in the direction of rotation of the sealing heads 1, immediately before the feeding device 4, a stripping device 5 is arranged for crown caps 3 which have not been processed in the sealing zone, for example as a result of the lack of the corresponding bottles, and therefore run back in the direction of the feeding device 4. The stripping device 5 has a horizontal plate 15, in which the feed device 4 is also integrated and which is supported by two vertical columns 24 fixed, not shown upper part of the vessel closure machine is removably attached.

In die Platte 15 ist konzentrisch und mittig zur Umlaufbahn 19 eine bogenartige, rinnenförmige Gleitbahn 11 eingearbeitet, deren Breite geringfügig größer ist als der Durchmesser eines Kronenkorkens 3. Die Gleitbahn 11 ist in Umlaufrichtung der Verschließköpfe 1 leicht schräg nach unten geneigt. Dabei ist der höher liegende Anfangsbereich der Gleitbahn 11, dessen Länge etwa einem Korkendurchmesser entspricht, mit geringem Abstand unterhalb der Umlaufbahn der Verschließköpfe 1 angeordnet und etwas weniger stark geneigt als der anschließende Bereich. Im Umlaufbereich der Mitnehmer 9 ist die Gleitbahn 11 mit einer nutförmigen Ausnehmung 12 versehen, in welche die Mitnehmer 9 mit Spiel eintauchen.In the plate 15 concentrically and centrally to the orbit 19, an arc-shaped, groove-shaped slideway 11 is incorporated, the width of which is slightly larger than the diameter of a crown cap 3. The slideway 11 is inclined slightly obliquely downward in the direction of rotation of the closing heads 1. The higher starting area of the slideway 11, the length of which corresponds approximately to a cork diameter, is arranged at a short distance below the orbit of the closing heads 1 and is slightly less inclined than the subsequent area. In the area around the driver 9, the slideway 11 is provided with a groove-shaped recess 12, into which the driver 9 plunges with play.

Im Anfangsbereich der Gleitbahn 11 ist beiderseits der Ausnehmung 12 jeweils ein als zylindrischer Dauermagnet ausgebildeter Magnet 6, 7 von unten in der Platte 11 befestigt, derart, daß seine obere Stirnfläche dicht unterhalb der Bodenfläche der Gleitbahn 11 liegt. Die beiden Magneten 6, 7 sind ausreichend stark, um einen nicht verarbeiteten Kronenkorken 3 entgegen der Kraft des Haltemagneten 2 aus der Vertiefung 10 eines vorbeilaufenden Verschließkopfs 1 schlagartig nach unten gegen den Anfangsbereich der Gleitbahn 11 zu ziehen. Dies ist auf der rechten Seite der Fig. 2 dargestellt. Ein weiterer, als zylindrischer Dauermagnet ausgebildeter Magnet 8 sitzt im Anschluß an die Magneten 6, 7 mittig unter der Umlaufbahn 19 bzw. der Ausnehmung 12, derart, daß seine obere Stirnfläche dicht unterhalb der Bodenfläche der Ausnehmung 12 liegt. Durch diesen Magneten 8 wird ein durch die Magneten 6, 7 angezogener Kronenkorken 3 weiter in Kontakt mit der geneigten Gleitbahn 11 gehalten, während er durch den in die Ausnehmung 12 eintauchenden Mitnehmer 9 in Umlaufrichtung vorgeschoben wird. Die seitliche Führung des Kronenkorkens 3 erfolgt hierbei durch die senkrechten Seitenflächen der Gleitbahn 11, die vom höher liegenden Anfangsbereich bis zum tiefer liegenden Endbereich der Gleitbahn 11 durchlaufen.In the initial region of the slideway 11, a magnet 6, 7 designed as a cylindrical permanent magnet is fastened on both sides of the recess 12 from below in the plate 11 such that its upper end face lies just below the bottom surface of the slideway 11. The two magnets 6, 7 are strong enough to suddenly pull an unprocessed crown cap 3 against the force of the holding magnet 2 out of the recess 10 of a passing closing head 1 against the initial region of the slideway 11. This is shown on the right side of FIG. 2. Another, designed as a cylindrical permanent magnet magnet 8 sits in connection to the magnets 6, 7 in the middle under the orbit 19 or the recess 12, such that its upper end face lies just below the bottom surface of the recess 12. This magnet 8 keeps a crown cap 3 attracted by the magnets 6, 7 in contact with the inclined slideway 11, while it is advanced in the circumferential direction by the driver 9 immersed in the recess 12. The lateral guidance of the crown cap 3 takes place here through the vertical side surfaces of the slideway 11, which run from the higher starting area to the lower end area of the slideway 11.

Beginnend am oberen Ende des stärker geneigten Bereichs ist die Gleitbahn 11 an beiden Längsseiten mit von oben am unteren Rand der Kronenkorken 3 angreifenden, parallelen Führungselementen 13, 14 in Form von schmalen Blechstreifen versehen, die auf der Platte 15 festgeschraubt sind. Die Führungselemente 13, 14 verhindern ein Abheben der Kronenkorken 3; die Mitnehmer 9 können ungehindert zwischen ihnen hindurchlaufen. Die Führungselemente 13, 14 sind über das untere Ende der Gleitbahn 11 hinaus verlängert und verlaufen im Bereich ihrer Verlängerung bogenförmig nach unten durch eine Durchtrittsöffnung 16 in der Platte 15. Die Durchtrittsöffnung 16 ist ausreichend dimensioniert, um einen ungehinderten Durchtritt eines Kronenkorkens 3 zu ermöglichen. Im Bereich der Magneten 6, 7 und 8 wird ein Kronenkorken 3 durch den Mitnehmer 9 desjenigen Verschließkopfs 1, von dem er abgezogen worden ist, über die ortsfeste Gleitbahn 11 hinweggeschoben. Die Förderwirkung des Mitnehmers 9 hält noch über den Magneten 8 hinaus an, bis der Kronenkorken 3 aus dem Wirkungsbereich sämtlicher Magneten im wesentlichen heraus ist. Im Anschluß daran wird der von den Führungselementen 13, 14 niedergehaltene Kronenkorken 3 durch den Hangabtrieb und seine Bewegungsenergie auf der Gleitbahn 11 weiter nach unten und durch die Durchtrittsöffnung 16 in der Platte 15 transportiert und schließlich von den gebogenen Enden der Führungselemente 13, 14 nach unten hin zu einem nicht gezeigten Sammelbehälter umgelenkt. Diese Enden können auch mit seitlichen Führungsflächen für die Kronenkorken 3 versehen sein.Beginning at the upper end of the more inclined area, the slideway 11 is provided on both longitudinal sides with parallel guide elements 13, 14 which engage from above on the lower edge of the crown caps 3 in the form of narrow metal strips which are screwed onto the plate 15. The guide elements 13, 14 prevent the crown caps 3 from being lifted off; the drivers 9 can pass freely between them. The guide elements 13, 14 are extended beyond the lower end of the slideway 11 and, in the region of their extension, run downward in the shape of an arc through a passage opening 16 in the plate 15. The passage opening 16 is dimensioned sufficiently to enable an unimpeded passage of a crown cap 3. In the area of the magnets 6, 7 and 8, a crown cork 3 is pushed over the stationary slideway 11 by the driver 9 of the closing head 1 from which it has been pulled off. The conveying effect of the driver 9 continues beyond the magnet 8 until the crown cap 3 is essentially out of the effective range of all magnets. Subsequently, the one held down by the guide elements 13, 14 Crown cork 3 by the slope drive and its kinetic energy on the slideway 11 further down and through the passage opening 16 in the plate 15 and finally deflected downward from the bent ends of the guide elements 13, 14 to a collecting container, not shown. These ends can also be provided with lateral guide surfaces for the crown caps 3.
