Abstract
Description
Eine Vorrichtung zum Entleeren eines Schlauchbeutels mit den im ersten Teil des Anspruchs 1 angegebenen Merkmalen ist aus
Die Verklebung bewirkt, daß der Inhalt des Schlauchbeutels, der bei Druckeinwirkung (üblicherweise durch einen von hinten einwirkenden Kolben) mittels einer in dem Aufnahmeteil vorhandenen Aufbrecheinrichtung geöffnet wird, nur durch die Austrittsöffnung des Aufnahmeteils und von dort an die vorgesehene Verwendungsstelle (beispielsweise den Einlaß eines Mischers), nicht aber aus dem kappenartigen Aufnahmeteil nach hinten fließen kann.The bonding causes the contents of the tubular bag, which is under pressure (usually by a rearwardly acting piston) is opened by means present in the receiving part Breaker, only through the outlet opening of the receiving part and from there to the intended use point (for example, the inlet of a Mischers), but not from the cap-like receiving part can flow backwards.
Eine weitere Funktion der Verklebung besteht darin, den stirnseitigen Schlauchbeutelbereich festzuhalten, so daß er beim Aufbringen des Entleerungsdrucks im Bereich des Aufnahmeteils nicht ausweichen kann, sondern der Folienbereich, der über einer die Aufbrecheinrichtung enthaltenden Vertiefung liegt, sich in diese hinein auswölbt und unter die zum Aufbrechen erforderliche Spannung gesetzt wird.Another function of the bond is to hold the front-side tubular bag area so that it can not escape when applying the emptying pressure in the region of the receiving part, but the film area, which lies above a recess containing the breaker bulges into it and under the Breaking up required tension is set.
Der zeitliche Ablauf beim Erreichen dieser Spannung ist insbesondere dann von Bedeutung, wenn zwei oder mehrere Schlauchbeutel in einem gemeinsamen Gerät und einer entsprechend mehrteiligen Aufnahmeeinrichtung gleichzeitig entleert werden. Handelt es sich beispielsweise um ein aus zwei Komponenten herzustellendes pastenartiges Material, so ist es erwünscht, daß der in kleinerer Menge vorliegende Katalysator-Bestandteil kurz vor dem Basis-Bestandteil auszuströmen beginnt, damit beide Bestandteile gleichzeitig den Mischer erreichen. Um diesen zeitlichen Ablauf zu gewährleisten, kommt es unter anderem darauf an, daß das Aufbrechen jeder Folie bei einer bestimmten Ausbringkraft erfolgt. Auch aus diesem Grund ist eine ordnungsgemäße Verklebung - oder generell Fixierung - zwischen dem Schlauchbeutel und dem die Aufbrecheinrichtung tragenden Aufnahmeteil von BedeutungThe timing of reaching this voltage is particularly important when two or more tubular bags are emptied simultaneously in a common device and a corresponding multi-part recording device. For example, if it is a paste-like material to be made of two components, it is desirable that the smaller amount of catalyst component begin to flow out shortly before the base component so that both components reach the mixer at the same time. Among other things, to ensure this timing, it is important that the breaking of each film takes place at a certain dispensing force. For this reason too, a proper bonding - or generally fixation - between the tubular bag and the receiving part carrying the breaker is important
Aus
Der Erfindung liegt die Aufgabe zugrunde, eine möglichst sichere und dichte Fixierung des Schlauchbeutels an dem Aufnahmeteil zu gewährleisten.The invention has for its object to ensure the most secure and tight fixation of the tubular bag on the receiving part.
Die Lösung dieser Aufgabe gelingt mit den im Anspruch 1 angegebenen Merkmalen.The solution of this problem is achieved with the features specified in claim 1.
Die danach an der Stirnseite des Schlauchbeutels angreifende Fixierung zwischen Schlauchbeutel und Aufnahmeteil findet im wesentlichen in der Ebene statt, in der die Aufbrecheinrichtung wirkt und sich der von ihr beaufschlagte Teil der Schlauchbeutelfolie befindet. Gleichzeitig liegt die Fixierstelle nahe an der Aufbrecheinrichtung. Aus beiden Gründen läßt sich beim Fixieren der Folie am Aufnahmeteil der oben erläuterte, für den Aufbrechvorgang wichtige Kraft/Zeit-Verlauf besser einhalten.The then acting on the front side of the tubular bag fixation between tubular bag and receiving part takes place substantially in the plane in which the breaker acts and is the acted upon by her part of the tubular bag film. At the same time the fixing point is close to the breaker. For both reasons, when fixing the film on the receiving part of the above-explained, important for the Aufbrechvorgang force / time course can be better met.
Im Gegensatz zum Stand der Technik ist bei der erfindungsgemäßen Gestaltung die Zone, in die der Schlauchbeutel beim Entleerungsvorgang hinein gequetscht wird, von jeglicher seitlichen Fixierung frei. Daher läßt sich der Ausbringkolben ungehindert vorschieben, bis der Schlauchbeutel vollständig zusammengedrückt und restlos entleert ist.In contrast to the prior art, in the design according to the invention, the zone into which the tubular bag is squeezed during the emptying process is free of any lateral fixation. Therefore, the dispensing piston can be pushed forward unhindered until the tubular bag is completely compressed and completely emptied.
Ferner wird durch die Tatsache, daß die Fixierstelle die im Schlauchbeutel zu erzeugende Öffnung unmittelbar umgibt, diejenige Substanzmenge klein, die sich innerhalb der Fixierung unter dem Schlauchbeutelboden sammeln kann, ohne an die Austrittsöffnung zu gelangen.Further, by the fact that the fixing point immediately surrounds the opening to be created in the tubular bag, that amount of substance which can collect within the fixation under the tubular bag bottom without reaching the outlet opening becomes small.
Die Gestaltung nach Anspruch 1 hat den Vorteil einer genauen Orientierung des Schlauchbeutels an der Querfläche des Aufnahmeteils. Die dabei angenommene Vorformung des Schlauchbeutelendes ist auch zur Erzielung einer ebenen und zu der Querfläche parallelen Fixierfläche am Schlauchbeutel günstig.The design according to claim 1 has the advantage of a precise orientation of the tubular bag on the transverse surface of the receiving part. The assumed preforming of the tubular bag end is also favorable for achieving a flat and parallel to the transverse surface fixing surface on the tubular bag.
Besteht die Fixierung gemäß Anspruch 2 in einer Verklebung, so ergibt sich der Vorteil, daß der Klebstoff praktisch nicht über den Rand des Aufnahmeteils nach außen treten kann, so daß auch Sauberkeit und Aussehen des gefüllten und mit dem Aufnahmeteil verbundenen Erzeugnisses verbessert werden. Gleichzeitig wird die für eine genügende Fixierung und Dichtung erforderliche Klebstoffmenge minimal.If the fixation according to claim 2 in a bond, so there is the advantage that the adhesive practically can not pass over the edge of the receiving part to the outside, so that the cleanliness and appearance of the filled and connected to the receiving part product can be improved. At the same time, the amount of adhesive required for sufficient fixation and sealing becomes minimal.
Die Ausgestaltung der Erfindung nach Anspruch 3 vermeidet, daß noch flüssige Teile des Klebstoffs in den Austrittsbereich der Substanz gelangen.The embodiment of the invention according to claim 3 avoids that still get liquid parts of the adhesive in the exit region of the substance.
Die Weiterbildung der Erfindung nach Anspruch 4 und 5 ist insofern zweckmäßig, als sich der gefüllte Schlauchbeutel ohne weiteres so vorformen läßt, daß er an seinem in das Aufnahmeteil einzuführenden Ende einen umlaufenden ringförmigen Vorsprung erhält, der bündig in die Nut eingeführt und in ihr fixiert werden kann.The development of the invention according to claim 4 and 5 is expedient in that the filled tubular bag can readily be preformed so that it receives at its end to be inserted into the receiving part a circumferential annular projection which is inserted flush into the groove and fixed in it can.
Anspruch 6 bezieht sich auf eine Aufbrecheinrichtung, die sich in Verbindung mit der erfindungsgemäßen stirnseitigen Fixierung zwischen Schlauchbeutel und Aufnahmeteil besonders gut eignet.Claim 6 refers to a breaker, which is particularly well suited in connection with the frontal fixation according to the invention between tubular bag and receiving part.
