Abstract
Description
Die
Erfindung bezieht sich auf ein Verfahren zum dichten Verschließen von
becherförmigen
Behältern
mit einer Folie mittels einer Vorrichtung, welche mit einer Schweißeinrichtung
ausgerüstet
ist, die zum Verschweißen
einer auf einen Behälter
aufgelegten Folie mit einem umlaufenden Rand desselben dient, bei
welcher mehrere Aufnahmen zum Einsetzen einzelner Behälter mit
jeweils gleichem Abstand zueinander an einem endlosen Träger angebracht werden,
der durch einen elektrischen Motor angetrieben und mit taktweisem
Vorschub in gleichbleibender Richtung jeweils um einen dem Abstand
der Aufnahmen voneinander entsprechenden Abschnitt gleichbleibender
Länge bewegt
wird, und bei welcher entlang des Trägers unterschiedliche Stationen
angeordnet werden, von denen eine die Schweißeinrichtung ist und an denen
pro Takt der Vorrichtung jeweils eine der Aufnahmen während des
Halts des Trägers positioniert
wird sowie auf eine Vorrichtung zur Durchführung des Verfahrens (

Die
Bei
dem bekannten Verfahren nach der eingangs erwähnten
Der Erfindung liegt die Aufgabe zugrunde, das eingangs geschilderte Verfahren bzw. die entsprechende Vorrichtung so weiterzubilden, daß eine zentrische Position der jeweiligen Aufnahme zumindest in der Schweißeinrichtung als eine der Stationen auf einfache Weise sichergestellt werden kann.Of the Invention is based on the object described at the outset To develop the method or the corresponding device in such a way that a centric Position of the respective receptacle at least in the welding device be secured as one of the stations in a simple way can.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,
- – daß zumindest die Schweißeinrichtung als eine der Stationen durch einen elektrischen Stellmotor parallel zum Träger verstellbar ausgeführt wird,
- – daß in Bewegungsrichtung des Trägers unmittelbar vor der Schweißeinrichtung ein mit dem Träger schlupffrei verbundener Abtaster angeordnet wird, der den Abstand zwischen zwei aufeinander folgenden Aufnahmen als Istwert erfaßt, und
- – daß der Abtaster mit einem Positionsgeber gekoppelt wird, der einen Vergleich des Istwerts mit dem ihm eingeprägten Sollwert des Abstands zwischen zwei Aufnahmen durchführt und der bei einer Abweichung der beiden Werte voneinander ein Signal an den Stellmotor liefert, durch welches die Schweißeinrichtung nach Maßgabe des jeweiligen Istwerts des Abstands jeweils in eine zu der in der Schweißeinrichtung haltenden Aufnahme zentrische Position verschoben wird.
- - That at least the welding device is designed as one of the stations by an electric servomotor parallel to the carrier adjustable
- - That in the direction of movement of the carrier immediately before the welding device with the carrier slip-free connected scanner is arranged, which detects the distance between two successive shots as an actual value, and
- - That the scanner ge with a position sensor is coupled, which performs a comparison of the actual value with the impressed setpoint value of the distance between two recordings and which delivers a signal to the actuator in a deviation of the two values from one another, by which the welding device in each case in accordance with the respective actual value of the distance the centric position held in the welding device is shifted.
Mit diesem Verfahren und der entsprechenden Vorrichtung wird der tatsächliche Abstand der Aufnahmen voneinander jeweils vor einer Station erfaßt, die dann rechtzeitig in eine zur jeweiligen Aufnahme zentrische Position gebracht werden kann. Es ist damit berücksichtigt, daß einerseits bereits bei der Anbringung der Aufnahmen an einem Träger die Abstände zwischen den einzelnen Aufnahmen nicht auf der ganzen Länge des Trägers exakt gleichlang sind. Diese Abstände können vielmehr innerhalb zulässiger Fertigungstoleranzen schwanken. Andererseits wird bei diesem Verfahren auch berücksichtigt, daß die Abstände zwischen den Aufnahmen sich ändern können, wenn der Träger bei längerem Betrieb der Vorrichtung infolge der auf ihn einwirkenden Zugkräfte nach und nach länger wird. Das mit diesem Verfahren auf einfache Weise durchführbare exakte Einstellen von Station und Aufnahme in eine zentrische Lage zueinander ist besonders bei der Schweißeinrichtung von Bedeutung, weil auf diese Weise ein positionsgenaues Verschweißen von Behälter und Folie sichergestellt ist. Die Aufnahmen selbst haben bei Einsatz dieses Verfahrens auf dem Träger eine feste, unverrückbare Position. Dadurch kann einerseits ihr Abstand voneinander durch den Abtaster mit großer Genauigkeit ermittelt werden. Andererseits ist damit für die Behälter sichergestellt, daß keine durch eine möglicherweise lockere Aufnahme bewirkte ruckelnde Bewegung auftreten kann, die besonders bei in den Behältern befindlichen dünnflüssigen Produkten schädlich wäre.With This method and the corresponding device will be the actual Distance between the recordings each detected in front of a station, the then timely in a centric position for each recording can be brought. It is thus taken into account that on the one hand already when attaching the images to a carrier the distances between the individual shots not on the whole length of the carrier are exactly the same length. These distances can rather within permissible manufacturing tolerances vary. On the other hand, this method also takes that the distances between the recordings can change, if the carrier for a longer time Operation of the device due to the tensile forces acting on it and after longer becomes. The exact feasible with this method in an easy way Setting station and recording in a centric position to each other is special with the welding device important because in this way a positionally accurate welding of container and foil is ensured. The pictures themselves are in use this procedure on the carrier a solid, immovable Position. This can on the one hand their distance from each other the scanner with great accuracy be determined. On the other hand, it is ensured for the container that no possibly through one Loose recording can cause jerky motion that may occur especially when in containers low-viscosity products would be harmful.
Das Verfahren nach der Erfindung wird anhand des in den Zeichnungen dargestellten Ausführungsbeispiels einer Vorrichtung nach der Erfindung erläutert.The Method according to the invention is based on the in the drawings illustrated embodiment a device according to the invention explained.
