Ein Aufgussbeutel dieser Art ist durch die EP 1 273 529 A1 bekannt. In dieser
Druckschrift ist aber nicht offenbart, welche Verfahrensschritte erforderlich sind, um
den Zugfaden auf wirtschaftliche Weise durch die einzelnen Ausnehmungen zu
ziehen und um dem Aufgussbeutel zu schlingen.An infusion bag of this type is known from
Aufgabe der Erfindung ist es daher, ein Verfahren zur maschinellen Umschlingung eines Aufgussbeutels mit einem Zugfaden zu schaffen, mittels dem in wenigen Verfahrensschritten derartige Aufgussbeutel maschinell und kostengünstig hergestellt werden können. Der dazu erforderliche Maschinenaufwand soll gering gehalten werden, auch sollen Störungen bei der Verstellung des Zugfadens weitgehend vermieden werden. Die einzelnen aufeinanderfolgenden Verstellbewegungen der auf den Zugfaden einwirkenden Verstellglieder sollen vielmehr einfach auszuführen sein, dennoch soll eine stets sichere Halterung des Zugfadens im Bereich des Aufgussbeutels und dessen nahezu vollständiges Ausdrücken gewährleistet sein.The object of the invention is therefore to provide a method for machine wrapping to create an infusion bag with a drawstring by means of which in few Process steps such infusion bag mechanically and inexpensively can be produced. The required machinery costs should be low are also meant to interfere with the adjustment of the drawstring be largely avoided. The single consecutive Adjustments of the acting on the drawstring adjusting should Rather, it should be easy to execute, but should always be a secure holder of Drawstring in the area of the infusion bag and its almost complete Be guaranteed expressions.
Gemäß der Erfindung ist das Verfahren zur maschinellen Umschlingung eines Aufgussbeutels dadurch gekennzeichnet, dass der Zugfaden zunächst auf einer Seite des Aufgussbeutels zumindest bis in Höhe der Ausnehmungen des Kopfteils U-förmig ausgerichtet und als Schlingen durch die Ausnehmungen zur anderen Seite hindurchgeführt wird, dass sodann im Bereich des Bodens des Aufgussbeutels zwei weitere Schlingen ausgeformt werden, die etwa gleichartig zu den im Bereich des Kopfteils gebildeten Schlingen verlaufen, und dass danach die dem Boden des Aufgussbeutels zugeordneten Schlingen durch die im Kopfteil gehaltenen Schlingen hindurchgeführt und zur Bildung der Zugglieder aufgezogen werden.According to the invention, the method of machine wrapping is a Infusion bag characterized in that the drawstring initially on a Side of the infusion bag at least up to the level of the recesses of the head part U-shaped aligned and as loops through the recesses to the other side is passed through that then in the region of the bottom of the infusion bag two Further loops are formed, which are approximately similar to those in the area of Head loop formed loops, and that after that the bottom of the Aufgussbeutels associated loops by held in the head part loops be passed and reared to form the tension members.
Zweckmäßig ist es hierbei, wenn die U-förmige Ausformung des Zugfadens mittels eines an den seitlichen Abstand der beiden im Kopfteil des Aufgussbeutels vorgesehenen Ausnehmungen angepassten Schiebers, eines Zuggliedes oder eines ähnlichen Führungsgliedes erfolgt, mittels dem der Zugfaden zwischen vorzugsweise zwei seitlich angeordneten Führungsrollen in Richtung des Aufgussbeutels verformbar ist.It is expedient here, if the U-shaped configuration of the drawstring means one at the lateral distance of the two in the head part of the infusion bag provided recesses adapted slider, a tension member or a similar guide member takes place by means of which the pull thread between preferably two laterally arranged guide rollers in the direction of the infusion bag is deformable.
Die dem Boden des Aufgussbeutels zugeordneten Schlingen können auf einfache Weise mit Hilfe zweier im Bereich des Bodens in den Aufgussbeutel eingearbeiteter Ausnehmungen oder mittels eines oder zwei mit Abstand zu dem Boden angeordneter Führungsglieder gebildet werden, durch die bzw. zwischen denen und dem Boden der Zugfaden hindurchgeführt wird, wobei die im Bereich des Bodens des Aufgussbeutels vorgesehenen Schlingen mit Hilfe einer Rolle oder dergleichen als Führungsglied ausgeformt werden können, die mit Abstand zu dem Boden angeordnet ist und zwischen der und dem Boden der Zugfaden jeweils hindurchgeführt wird. The loops associated with the bottom of the infusion bag can be simple Way with the help of two in the area of the soil in the infusion bag incorporated Recesses or by means of one or two spaced from the ground arranged guide members are formed by or between which and the bottom of the drawstring is passed, taking in the area of the bottom the infusion bag provided loops by means of a roller or the like can be formed as a guide member, the distance from the ground is arranged and between the and the bottom of the drawstring respectively is passed.
Bei mit Hilfe einer Rolle als Führungsglied gebildeten Schlingen sollte der Zugfaden, um ein seitliches Abrutschen zu verhindern, im Bereich des Bodens in in diesen eingearbeiteten oder eingeformten Einschnitten geführt werden.When using a role as a guide member loops formed the drawstring, to prevent lateral slipping, in the area of the floor in in this incorporated or molded incisions are performed.
Wirtschaftlich ist es, die dem Kopfteil und dem Boden des Aufgussbeutels zugeordneten Schlingen jeweils durch ein gesondertes Verstellglied z. B. in Form einer Doppelnadel zu bilden und die dem Kopfteil des Aufgussbeutels zugeordneten Schlingen bei der Bildung der dem Boden zugeordneten Schlingen durch ein die im Kopfteil ausgeformten Schlingen hindurchzuführenden Verstellglied zu arretieren.Economically, it is the headboard and the bottom of the infusion bag associated loops each by a separate adjusting z. B. in shape to form a double needle and assigned to the head part of the infusion bag Loops in the formation of the loops associated with the soil by a in the To lock head part formed loops to be passed adjusting member.
Eine besonders einfache Umschlingung ist zu bewerkstelligen, wenn das zur Bildung der das Kopfteil des Aufgussbeutels durchgreifenden Schlingen verwendete Verstellglied in den Bereich des Bodens verstellt, vorzugsweise verschwenkt und von den Schlingen gelöst wird und dass danach mittels dieses Verstellgliedes die Schlingen im Bereich des Bodens ausgeformt werden. Bei dieser Verfahrensweise ist nur ein als Doppelnadel gestaltetes Verstellglied zur Bildung der Umschlingungen erforderlich.A particularly simple wrap is to accomplish, if that to education which used the head part of the infusion bag sweeping loops Adjustment member adjusted in the region of the bottom, preferably pivoted and of the loops is released and that thereafter by means of this adjusting the Slings are formed in the area of the soil. In this procedure is only designed as a double needle adjustment for forming the wraps required.
Zur gemeinsamen Ausformung der das Kopfteil durchgreifenden Schlingen und der im Bereich des Bodens vorgesehenen Schlingen können aber auch zwei mit seitlichem Abstand zueinander angeordnete Hakennadeln vorgesehen werden, die bei der Ausformung der im Bereich des Bodens zu bildenden Schlingen zweckmäßigerweise, um Verhakungen zu vermeiden, in einen Freiraum der dem Kopfteil zugeordneter Schlingen verdreht werden.For joint shaping of the head part sweeping loops and the However, slings provided in the area of the floor can also be two with lateral spaced hook needles are provided, the in forming the loops to be formed in the area of the ground expediently, in order to avoid entanglements, in a free space of the Head part associated slings are twisted.
Eines oder beide Zugglieder des Zugfadens können vorzugsweise in den Endbereichen mit Etiketten oder ähnlichem versehen werden.One or both tension members of the drawstring can preferably in the End areas are provided with labels or the like.
Um den Transport des Aufgussbeutels zu erleichtern, ist es ferner angebracht, den den Aufgussbeutel umgreifenden Zugfaden nach dem Anbringen des Etikettes zum Beispiel mit Hilfe einer verstellbaren Rolle derart zu spannen, dass das Etikett an dem Kopfteil des Aufgussbeutels anliegt. In order to facilitate the transport of the infusion bag, it is also appropriate to the the infusion bag embracing drawstring after attaching the label to Example with the help of an adjustable role to stretch so that the label abuts the head of the infusion bag.
Dies kann in der Weise erfolgen, dass überschüssige Teile des Zugfadens nach dem Verspannen mit dem Aufgussbeutel mit Hilfe eines verstellbaren Schiebers oder einer Rolle in dem Aufgussbeutel oder zwischen zwei Kammern verwahrt werden.This can be done in such a way that excess parts of the drawstring after the Clamp with the infusion bag using an adjustable slider or a roll in the infusion bag or between two chambers are kept.
Angezeigt ist es auch, die beiden im Bereich des Bodens des Aufgussbeutels gebildeten Schlingen beim Aufziehen der Schlingen in einer Kulisse oder dergleichen zu führen.It is also shown, the two in the area of the bottom of the infusion bag formed loops when putting the slings in a backdrop or to lead the like.
Werden Aufgussbeutel nach dem erfindungsgemäßen Verfahren gefertigt, so ist nicht nur gewährleistet, dass einen Aufgussbeutel jeweils zwei Umschlingungen, ausgerichtet in den vorgesehenen Bereichen, umgeben, um diesen auspressen zu können, sondern vor allem ist eine wirtschaftliche maschinelle Herstellung der Umschlingungen in kurzer Zeit möglich, ohne dass dabei Störungen des Betriebsablaufes auftreten. Aufgrund der nur wenigen Verfahrensschritte, wobei die Verstellglieder nahezu stets geradlinig verstellt werden, ist nämlich sichergestellt, dass Überbeanspruchungen des Zugfadens, zum Beispiel durch Umlenkungen, ausgeschlossen sind, so dass dieser nicht beschädigt wird und dadurch bedingte Betriebsunterbrechungen nicht in Kauf zu nehmen sind.If infusion bags are produced by the method according to the invention, then this is not only ensures that an infusion bag has two wraps, aligned in the intended areas, surrounded to squeeze this out but, above all, is an economical machine manufacturing the Wraps in a short time possible, without disturbing the Operating sequence occur. Due to the few process steps, the Actuators are almost always rectilinearly adjusted, namely, it is ensured that overstressing the drawstring, for example by deflections, are excluded, so that this is not damaged and conditional Business interruptions are not to be accepted.
Des weiteren ist der Bauaufwand zur Betätigung der als Hakennadel, Doppelnadel oder Schieber ausgebildeten Verstellglieder durch Zug- oder Druckkräfte gering, auch sind die Verstellglieder problemlos zu verstellen und zu steuern, eine kostengünstige Umschlingung von Aufgussbeuteln mittels Zugfäden ist demnach leicht zu bewerkstelligen. Das vorschlagsgemäße Verfahren ermöglicht es demnach, Aufgussbeutel mit zwei Umschlingungen ohne Schwierigkeiten herzustellen.Furthermore, the construction cost to operate as a hook needle, double needle or slide trained adjusting by tensile or compressive forces low, Also, the adjusting members are easy to adjust and control, one Cost-effective wrapping of infusion bags by means of drawstrings is accordingly easy to do. The proposed method thus makes it possible Make infusion bags with two wraps without difficulty.

Der Zugfaden 11, der auf einer Rolle 12 bevorratet ist und in der erforderlichen
Länge mittels einer Schere 15 abgetrennt wird, wird gemäß den nachfolgenden
Verfahrensschritten um den Aufgussbeutel 1 geschlungen und zum Schluss mit
einem Etikett 10 versehen. Zunächst wird der Zugfaden 11 unterhalb des
Aufgussbeutels 1 ausgerichtet (Fig. 1) und nachfolgend mittels eines Schiebers 16 in
die in Figur 2 gezeigte Lage gebracht. Unter Zuhilfenahme zweier mit Abstand
zueinander angeordneter Rollen 13 und 14 ist der Zugfaden 11 auf der Rückseite
des Aufgussbeutels 1 derart ausgerichtet, dass der Zugfaden 11 in Höhe der
Ausnehmungen 4 und 6 bzw. 5 und 7 verläuft.The
Sodann werden, wie dies in den Figuren 3, 4 und 5 dargestellt ist, durch ein erstes
Verstellglied 21 und ein zweites Verstellglied 22, die als Doppelnadel ausgebildet
sind, Schlaufen 31 und 32 bzw. 33 und 34 ausgeformt. Die Schlaufen 31 und 32, die
über ein an dem Aufgussbeutel 1 anliegendes Zwischenstück 35 miteinander
verbunden sind, durchgreifen hierbei die im Kopfteil 2 vorgesehenen Ausnehmungen
4 bzw. 5, die Schlaufen 33 und 34 die im Boden 3 vorgesehenen Ausnehmungen 6
und 7. Mit Hilfe eines dritten Verstellgliedes 23, das ebenfalls als Doppelnadel
gestaltet ist und durch die Schlingen 31 und 32 zugeführt wird, werden die Schlingen
33 und 34 gemäß Figur 6 erfasst und gemäß Figur 7 durch die Schlingen 31 bzw. 32
gezogen. Sodann werden die Schlingen 33 und 34, die dabei durch eine Kulisse 17
geführt werden, aufgezogen, so dass diese Teile des Zugfadens 11 zwei Zugglieder
11' und 11" bilden, an denen das Etikett 10 zu befestigen ist.Then, as shown in Figures 3, 4 and 5, by a
Die dem Boden 3 des Aufgussbeutels 1 zugeordneten Schlingen 33 und 34 können
auch, wie dies in Figur 10 gezeigt ist, mit Hilfe einer Rolle 18 ausgeformt werden. Die
Rolle 18 ist hierbei mit Abstand zu dem Boden 3 angeordnet, so dass der Zugfaden
11 zwischen diesem und der Rolle 18 mit Hilfe des Verstellgliedes 22
hindurchgezogen werden kann. Der Boden 3 des Aufgussbeutels 1 könnte bei dieser
Verfahrensweise, um ein Abrutschen des Zugfadens zu verhindern, mit Einschnitten
versehen sein.The
ln den Figuren 11, 12, 13 und 14 ist dargestellt, dass sowohl die Schlingen 31 und 32
wie auch die Schlingen 33 und 34 mit Hilfe des Verstellgliedes 21 auszuformen sind.
Nach dem Ausformen der Schlingen 31 und 32 wird das Verstellglied 21 gemäß der
in Figur 11 eingezeichneten Linie verschwenkt, so dass dieses sich vor den
Ausnehmungen 6 und 7 befindet und durch diese zur Aufnahme des Zugfadens 11
hindurchgeführt werden kann (Fig. 13). Nach dem vollständigen oder teilweisen
Aufziehen der Schlingen 31 und 32 durch die Ausnehmungen 6 und 7, sowie die
Schlingen 31 und 32 hindurch wird an den dadurch gebildeten Zuggliedern 11' und
11" das Etikett 10 befestigt (Fig. 15 und 16).FIGS. 11, 12, 13 and 14 show that both the
An Stelle des Verstellgliedes 21 können auch, wie dies in Figur 13 mit eingezeichnet
ist, zwei einzelne Hakennadeln 24 und 25 vorgesehen werden. Damit beim
Zurückführen der Hakennadeln 24 und 25 keine Verhakungen auftreten, sollten diese
derart in einen Freiraum der Schlingen 31 und 32 verdreht werden, dass eine
Berührung mit dem Zugfaden 11 nicht eintritt.Instead of the adjusting
Damit das Etikett 10 beim Transport des Aufgussbeutels 12 an diesem anliegt, wie
dies in Figur 18 gezeigt ist, ist es zweckmäßig, überschüssige Teile 11''' und 11""
des Zugfadens 1 zu verwahren. Dies ist in der Weise zu bewerkstelligen, dass
gemäß Figur 16 mit Hilfe eines Stabes 19, der auf der Rückseite des Aufgussbeutels
1 zwischen diesem und den Umschlingungen des Zugfadens 11 einzuführen ist,
gemäß Figur 17 von dem Aufgussbeutel 1 wegbewegt wird. Die Schlingen 31 und 32
werden dabei zugezogen, das Etikett liegt am Kopfteil 2 an, so dass die
überschüssigen Teile 11'" und 11"" des Zugfadens 1 im Aufgussbeutel 1 verwahrt
werden können.Thus, the
Dies ist gemäß den Figuren 19 und 20 mit Hilfe eines Schiebers 20 oder eines
Stabes 20' zu bewerkstelligen. Der Schieber 20 wird dazu durch den Boden 3 des
Aufgussbeutels 1 gestoßen, so dass der überschüssige Teil 11'" zwischen den
