Description

Die Erfindung betrifft ein Verfahren zur Verarbeitung von Faserbündeln, wobei Faserbündelabschnitte von einem Faserbündel abgeschnitten werden. Die Erfindung betrifft weiterhin eine Vorrichtung zur Verarbeitung von Faserbündeln. Bei den Faserbündeln handelt es sich insbesondere um Bündel von Fasern bzw. Filamenten aus thermoplastischem Kunststoff und nach einer Ausführungsform um Bündel aus Monofilamenten aus thermoplastischem Kunststoff. Die Fasern bzw. Filamente aus thermoplastischem Kunststoff werden zweckmäßigerweise mittels einer Extrusionsvorrichtung extrudiert.The invention relates to a method for processing fiber bundles, wherein fiber bundle sections are cut off from a fiber bundle. The invention further relates to a device for processing fiber bundles. The fiber bundles are, in particular, bundles of fibers or filaments made of thermoplastic material and, in one embodiment, bundles of monofilaments of thermoplastic material. The fibers or filaments of thermoplastic material are expediently extruded by means of an extrusion device.

Aus der Praxis sind Verfahren der eingangs beschriebenen Art in verschiedenen Ausführungsformen bekannt. In der Regel wird im Anschluss an eine Extrusionsvorrichtung für Filamente ein Strangwickler bzw. Borstenwickler positioniert und die Filamente werden zunächst aufgewickelt. Anschließend werden die Filamente durchtrennt und zu einem Faserbündel (sogenanntes Hank) zusammengefasst. Daraufhin werden die Faserbündel üblicherweise mit Folie oder Papier umwickelt. Im Anschluss daran werden die Faserbündel in Faserbündelabschnitte (sogenannte Pucks) aufgetrennt. Diese von dem Faserbündel abgetrennten Faserbündelabschnitte werden dann weiterverarbeitet bzw. verpackt. Das Umwickeln der Faserbündel mit Folie oder Papier dient zur Stabilisierung bzw. Fixierung der Faserbündel, insbesondere für das Abtrennen der Faserbündelabschnitte. Dieses Umwickeln ist aber aufwendig bzw. kostenaufwendig und die Folie oder das Papier muss in der Regel nachträglich wieder entfernt werden. Das wird beispielsweise mit Hilfe einer wasserlöslichen Folie realisiert.From practice, methods of the type described above are known in various embodiments. In general, following a filament extrusion device, a strand winder or bristle winder is positioned and the filaments are first wound up. Subsequently, the filaments are severed and combined to form a fiber bundle (so-called Hank). Then the fiber bundles are usually wrapped with foil or paper. Subsequently, the fiber bundles are separated into fiber bundle sections (so-called pucks). These fiber bundle sections separated from the fiber bundle are then further processed or packed. The wrapping of the fiber bundles with foil or paper serves to stabilize or fix the fiber bundles, in particular for the separation of the fiber bundle sections. However, this wrapping is complicated or costly and the film or paper must be removed later usually again. This is realized, for example, with the aid of a water-soluble film.

Anschließend wird der untere Greifer 9 wieder geschlossen bzw. wieder in Eingriff mit dem Faserbündel 1 gebracht und der Vorschubgreifer 10 wird geöffnet bzw. außer Eingriff mit dem Faserbündel 1 gebracht. Der Vorschubgreifer 10 wird wieder vertikal nach oben zurückbewegt und zwar vorzugsweise entsprechend dem vorangegangenen Hub des Faserbündels 1. Im Anschluss daran wird der untere Greifer 9 wieder geöffnet sowie der Vorschubgreifer 10 wieder geschlossen und das Faserbündel 1 mit dem daran angeschlossenen oberen Greifer 8 und dem daran angeschlossenen Vorschubgreifer 10 wird wiederum um einen Hub vorgeschoben und ein Faserbündelabschnitt 2 wird von dem Faserbündel 1 abgetrennt und so weiter fort. - Es liegt im Rahmen der Erfindung, dass der untere Greifer 9 während der Vorschubbewegungen des Faserbündels 1 in Richtung Schneideinrichtung 11 in der gleichen horizontalen Position bzw. Ebene verbleibt. Dagegen wird der obere Greifer 8 entsprechend den Vorschubbewegungen des Faserbündels 1 vertikal nach unten in Richtung Schneideinrichtung 11 nach und nach verfahren.Subsequently, the lower gripper 9 is closed again or brought back into engagement with the fiber bundle 1 and the feed gripper 10 is opened or disengaged from the fiber bundle 1. The feed gripper 10 is again moved back vertically upwards, and preferably according to the previous stroke of the fiber bundle 1. In the following the lower gripper 9 is opened again and the feed gripper 10 is closed again and the fiber bundle 1 with the attached upper gripper 8 and the attached feed gripper 10 is in turn advanced by one stroke and a fiber bundle section 2 is separated from the fiber bundle 1 and so on continued. It is within the scope of the invention that the lower gripper 9 remains in the same horizontal position or plane during the advancing movements of the fiber bundle 1 in the direction of the cutting device 11. In contrast, the upper gripper 8 is moved in accordance with the feed movements of the fiber bundle 1 vertically downwards in the direction of cutting device 11 gradually.

In der Fig. 8 ist dargestellt, dass nach bevorzugter Ausführungsform und im Ausführungsbeispiel die mit der Schneideinrichtung 11 abgetrennten und von dem Bündelgreifer 12 ergriffenen und abgelegten Faserbündelabschnitte 2 in einem als Transportsack ausgeführten Transport- und/oder Lagerbehälter 15 abgelegt werden. Der Transportsack wurde dazu von unten über eine Ablageeinrichtung 16 gezogen, die bevorzugt und im Ausführungsbeispiel eine Mehrzahl von vertikalen Kammern 17 aufweist. Die Faserbündelabschnitte 2 werden in diesen vertikalen Kammern 17 übereinander gestapelt. Zweckmäßigerweise befindet sich unter dem Transportsack eine in den Figuren nicht dargestellte Wägezelle. Bei Erreichen des gewünschten Gewichtes des gefüllten Transportsackes wird der Transportsack von der Ablageeinrichtung 16 entfernt und dazu der untere Boden 19 der Ablageeinrichtung 16 geöffnet. Somit rutschen die gestapelten Faserbündelabschnitte 2 in ihrer gestapelten bzw. ausgerichteten parallelen Orientierung in den Transportsack. Durch diese parallele Ausrichtung der Faserbündelabschnitte 2 wird eine besonders kompakte Stapelung der Faserbündelabschnitte 2 und ein besonders platzsparender Transport gewährleistet.In the Fig. 8 It is shown that according to a preferred embodiment and in the embodiment separated with the cutting device 11 and taken and deposited by the bundle gripper 12 fiber bundle sections 2 are stored in a designed as a transport bag transport and / or storage container 15. For this purpose, the transport bag was pulled from below over a depositing device 16, which preferably and in the exemplary embodiment has a plurality of vertical chambers 17. The fiber bundle sections 2 are stacked in these vertical chambers 17. Appropriately, located below the transport bag, a load cell, not shown in the figures. When the desired weight of the filled transport bag is reached, the transport bag is removed from the depositing device 16 and the lower bottom 19 of the depositing device 16 is opened for this purpose. Thus, the stacked fiber bundle sections 2 slip in their stacked orientation in the transport bag. This parallel alignment of the fiber bundle sections 2 ensures a particularly compact stacking of the fiber bundle sections 2 and a particularly space-saving transport.

In den Figuren wurde nicht dargestellt, dass nach einer bevorzugten Ausführungsform die mit der Schneideinrichtung 11 abgeschnittenen Faserbündelabschnitte 2 abwechselnd von zwei Bündelgreifern 12 ergriffen werden können und auch abwechselnd in zwei Transport- und/oder Lagerbehältern 15 abgelegt werden können. Dadurch wird in vorteilhafter Weise eine schnelle Taktzeit für den Betrieb der erfindungsgemäßen Vorrichtung erzielt. - Weiterhin wurde auch nicht dargestellt, dass die Greifer mit Hilfe eines Industrieroboters realisiert werden können und/oder auch Kettenfördersysteme in die erfindungsgemäße Vorrichtung integriert sein können.In the figures, it has not been shown that, according to a preferred embodiment, the fiber bundle sections 2 cut off by the cutting device 11 can be alternately gripped by two bundle grippers 12 and can also be deposited alternately in two transport and / or storage containers 15. As a result, a fast cycle time for the operation of the device according to the invention is advantageously achieved. - Furthermore, it was also not shown that the gripper can be realized with the help of an industrial robot and / or chain conveyor systems can be integrated into the device according to the invention.
