Description

Eine Vorrichtung zum Entleeren eines Schlauchbeutels mit den im ersten Teil des Anspruchs 1 angegebenen Merkmalen ist aus DE 295 01 255 U bekannt. Der Schlauchbeutel wird dort in das kappenartige Aufnahmeteil so eingelegt, daß seine Stirnseite an der Stützwand des Aufnahmeteils anliegt, und an seinem Umfang mit der Umfangswand des Aufnahmeteils verklebt oder in sonstiger Weise an dieser fixiert.A device for emptying a tubular bag with the features specified in the first part of claim 1 from DE 295 01 255 U known. The tubular bag will be there in the cap-like receiving part inserted so that its front side abuts against the support wall of the receiving part, and at its Glued circumference with the peripheral wall of the receiving part or otherwise fixed to this.

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, when pressure is applied (usually by one of Rear acting piston) by means of a in the receiving part existing breaker is opened, only by the Outlet opening of the receiving part and from there to the intended Place of use (for example, the inlet of a Mixer), but not from the cap-like receiving part can flow behind.

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 the Hold the front tubular bag area so that he when applying the evacuation pressure in the region of the receiving part can not evade, but the film area, the above a recess containing the breaker lies, arching into it and breaking into it required voltage 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 especially important if two or more Tubular bag in a common device and one accordingly multi-part receiving device simultaneously emptied become. For example, is it one of two components paste material to be produced, so it is desirable that the present in a smaller amount catalyst component just before the base ingredient starts to pour out, so that both components reach the mixer at the same time. To ensure this timing, comes It inter alia on the fact that the breaking up of each slide takes place at a certain application force. Also from this Reason is a proper gluing - or general fixation - Between the tubular bag and the breaker bearing receiving part of importance

Aus DE 94 00 524 U ist eine weitere Vorrichtung zum Entleeren eines Schlauchbeutels bekannt. Dort ist am vorderen Ende des Schlauchbeutels ein Ring mit einer Dichtfläche angeklebt, die beim Entleervorgang mit einer in einem kappenartigen Aufnahmeteil vorgesehen Anlage dichtend zusammenwirkt.From DE 94 00 524 U is another device for emptying a tubular bag known. There is at the front A ring with a sealing surface glued to the end of the tubular bag, when emptying with one in a cap-like Receiving part provided plant sealingly cooperates.

Der Erfindung liegt die Aufgabe zugrunde, eine möglichst sichere und dichte Fixierung des Schlauchbeutels an dem Aufnahmeteil zu gewährleisten.The invention is based on the object as possible safe and tight fixation of the tubular bag on the receiving part to ensure.

Die Lösung dieser Aufgabe gelingt mit den im Anspruch 1 angegebenen Merkmalen.The solution of this problem succeeds in claim 1 specified characteristics.

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 attacking on the front side of the tubular bag Fixation between tubular bag and receiving part finds held substantially in the plane in which the breaker acts and the acted upon by her part of Tubular bag film is located. At the same time the fixation point lies near the breaker. For both reasons can be when fixing the film on the receiving part of the above explained, for the breaking process important force / time course better comply.

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 is in the inventive Design the zone into which the tubular bag squeezed in during the emptying process, of any lateral fixation free. Therefore, the dispensing piston can be advance unhindered until the tubular bag is complete 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.Furthermore, by the fact that the fixing point the immediately surrounding the opening to be produced in the tubular bag, the amount of substance small that is within the fixation can collect under the tubular bag bottom, without the To get to the exit opening.

Die Gestaltung nach Anspruch 2 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 2 has the advantage of accurate Orientation of the tubular bag on the transverse surface of the Receiving part. The assumed preforming of the tubular bag end is also to achieve a level and to the Transverse surface parallel fixing surface on the tubular bag low.

Besteht die Fixierung gemäß Anspruch 3 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. Does the fixation according to claim 3 in a bond, so there is the advantage that the adhesive is practical can not pass out over the edge of the receiving part, so that also cleanliness and appearance of the filled and with the Receiving part connected product can be improved. At the same time, that is sufficient for a sufficient fixation and sealing Required amount of adhesive minimal.

Die Ausgestaltung der Erfindung nach Anspruch 4 vermeidet, daß noch flüssige Teile des Klebstoffs in den Austrittsbereich der Substanz gelangen.The embodiment of the invention according to claim 4 avoids that still liquid parts of the adhesive in the exit area get the substance.

Die Weiterbildung der Erfindung nach Anspruch 5 und 6 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 5 and 6 is appropriate insofar as the filled tubular bag readily preformed so that he at his in the receiving part to be inserted end a circumferential annular Get projection that is flush inserted into the groove and into it can be fixed.

Anspruch 7 bezieht sich auf eine Aufbrecheinrichtung, die sich in Verbindung mit der erfindungsgemäßen stirnseitigen Fixierung zwischen Schlauchbeutel und Aufnahmeteil besonders gut eignet.Claim 7 refers to a breaker, which in conjunction with the frontal end of the invention Fixation between tubular bag and receiving part especially good.

FIG. 3
an end view of the receiving part in the direction of arrow III-III of Figure 2.

Gemäß der Zeichnung ist der aus einer Kunststoffolie hergestellte Schlauchbeutel 10 generell zylindrisch und an seinen Enden jeweils mit einem Clip 11 verschlossen.According to the drawing, the tubular bag 10 made of a plastic film is generally cylindrical and closed at its ends in each case with a clip 11 .

Das aus Kunststoff einstückig gespritzte Aufnahmeteil 12 weist eine Querwand 13 auf, die eine Stützfläche für das Ende des Schlauchbeutels 10 bildet. In Richtung des Schlauchbeutels (in der Zeichnung nach oben) wird die Querwand 13 von einer Umfangswand 14 umgeben. In entgegengesetzter Richtung (in der Zeichnung nach unten) geht von der Querwand 13 eine Vertiefung 15 aus, die in einer Austrittstülle 16 mündet. Gemäß Figur 3 hat die Vertiefung 15 in der Draufsicht etwa die Form eines Kreissegments, wobei ihre gekrümmte Wand parallel zur Umfangswand 14 des Aufnahmeteils 12 verläuft.The integrally molded plastic injection-molded part 12 has a transverse wall 13 , which forms a support surface for the end of the tubular bag 10 . In the direction of the tubular bag (in the drawing upwards), the transverse wall 13 is surrounded by a peripheral wall 14 . In the opposite direction (in the drawing down) goes from the transverse wall 13 from a recess 15 , which opens into an outlet nozzle 16 . According to Figure 3, the recess 15 in plan view has approximately the shape of a circle segment, wherein its curved wall is parallel to the peripheral wall 14 of the receiving part 12 .

Innerhalb der Vertiefung 15 sind zu beiden Seiten der zentrisch angeordneten Austrittstülle 16 zwei Dorne 17 angeformt. Die Dorne 17 sind in ihrer Länge so bemessen, daß ihre Spitzen gegenüber der von der Querwand 13 gebildeten Stützfläche zurückgesetzt sind.Within the recess 15 16 two mandrels 17 are integrally formed on both sides of the centrally arranged outlet spout 16. The mandrels 17 are so dimensioned in their length that their tips are set back relative to the support surface formed by the transverse wall 13 .

Die Vertiefung 15 ist von einer Ringnut 18 umgeben, die längs der Umfangswand 14 verläuft und, soweit es die gegebenen Abmessungen zulassen, von der Vertiefung 15 durch einen Steg 19 getrennt ist.The recess 15 is surrounded by an annular groove 18 which extends along the peripheral wall 14 and, as far as the given dimensions allow, is separated from the recess 15 by a web 19 .

Der gefüllte und mit den Clips 12 verschlossene Schlauchbeutel 10 wird vor seinem Einsetzen in den Aufnahmeteil 12 so vorgeformt, daß er an dem entsprechenden Ende einen umlaufenden Ringvorsprung 20 erhält. Bei diesem Verformungsvorgang wird gleichzeitig der untere Beutelzipfel mit dem unteren Clip 11 nach innen gedrückt, so daß eine - mit Ausnahme des Ringvorsprungs 20 - im wesentlichen ebene Stirnfläche entsteht.The filled and closed with the clips 12 tubular bag 10 is preformed before its insertion into the receiving part 12 so that it receives a circumferential annular projection 20 at the corresponding end. In this deformation process, the lower bag tab with the lower clip 11 is pressed inward at the same time, so that - with the exception of the annular projection 20 - is formed substantially flat face.

Beim anschließenden Einführen des Schlauchbeutels 10 in den Aufnahmeteil 12 gelangt der Ringvorsprung 20 in die mit Klebstoff 21 gefüllte Ringnut 18, wo die Fixierung stattfindet.During the subsequent insertion of the tubular bag 10 in the receiving part 12 of the annular projection 20 enters the filled with adhesive 21 annular groove 18 , where the fixation takes place.

Anstelle der beschriebenen Verklebung kann auch mit einer Verschweißung gearbeitet werden, wobei die zum Verschweißen erforderliche Wärme dem Bereich der Ringnut 18 und dem darin befindlichen Ringvorsprung 20 des Schlauchbeutels 10 zugeführt wird.Instead of the described bonding can also be carried out with a weld, wherein the heat required for welding is supplied to the region of the annular groove 18 and the annular projection 20 of the tubular bag 10 therein.

Ferner kann anstelle der in der Zeichnung dargestellten beiden Dorne 17 auch eine anders gestaltete, beispielsweise mit einem Messer arbeitende Aufbrecheinrichtung vorgesehen sein.Furthermore, instead of the two pins 17 shown in the drawing, a differently shaped, for example, working with a knife breaking device may be provided.

Als weitere Variante kann die Querwand 13 zur Aufnahme des unteren Beutelzipfels samt Clip 11 mit einer Vertiefung versehen sein.As a further variant, the transverse wall 13 may be provided with a recess for receiving the lower bag lobes together with the clip 11 .
