Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1 bzw. 6 als auch eine Vorrichtung gemäß dem Oberbegriff des Patentanspruchs 9.The invention relates to a method according to the preamble of patent claims 1 and 6 as well as a device according to the preamble of claim 9.

- Einbringen eines Trennpapiers in das Innere eines textilen Schlauchs;
- Bereitlegen des Schlauchs derart, dass er in zwei übereinander liegenden Lagen flächig vorliegt;
- oberflächliches Anschmelzen einer ersten begrenzten Fläche der oberen Schlauchlage;
- oberflächliches Anschmelzen einer zweiten, der ersten begrenzten Fläche gegenüberliegenden begrenzten Fläche der unteren Schlauchlage, und
- Durchtrennen des Schlauchs im Bereich der begrenzten Fläche
- Introducing a release paper into the interior of a textile tube;
- Providing the tube such that it is present in two superimposed layers surface;
- superficial melting of a first limited area of the upper tube layer;
- Superficial melting of a second, the first limited area opposite limited surface of the lower tube layer, and
- Cutting the hose in the area of the limited area
Bei einem mit einem solchen Verfahren erzeugten Produkt soll ein Herausfallen von Fadenstücken im Schnittkantenbereich verhindert werden, um ein den Sicherheitsvorschriften entsprechendes, zuverlässiges Bauteil in Form eines auf beiden Seiten aufgeschnittenen Schlauchabschnitts zu erzeugen. Dieses Bauteil soll als so genannter Schrumpfschlauch verwendet werden. Die Wärmbehandlung soll in einer solchen Weise durchgeführt werden, dass die z.B. thermoplastischen Filamente und Fäden des textilen Schlauchs in dem wärmebeharadelten, begrenzten Flächenbereich, der als so genannter "geschweißter Balken" bezeichneter ist, leicht anschmelzen. Obwohl durch das Anbringen eines Trennpapiers im Inneren des Schlauchs verhindert werden soll, dass bei dem oberflächlichen Anschmelzen der äußeren Oberflächen der unteren und oberen Schlauchlagen ein Verkleben oder Verschweißen der gegenüberliegenden Innenwände des Schlauchs nicht stattfindet, bleibt die Gefahr, dass im Bereich der späteren Durchtrennung des Schlauchs liegende Fäden und Filamente durch Verkleben oder Verschweißen arretiert werden.In a product produced by such a method falling out of pieces of thread in the cutting edge region is to be prevented in order to produce a safety component corresponding, reliable component in the form of a section cut open on both sides hose section. This component is to be used as a so-called shrink tubing. The heat treatment should be carried out in such a way that the e.g. thermoplastic filaments and filaments of the textile tube in the heat-needled, limited area, which is referred to as a so-called "welded bar", melt easily. Although the application of a release paper inside the tube to prevent that in the surface melting of the outer surfaces of the lower and upper tube layers gluing or welding of the opposite inner walls of the hose does not take place, the danger remains that in the later section of the Tubing threads and filaments are locked by gluing or welding.
Ein Verschmelzen oder Verkleben der Filamente und Fäden ist für ein als Schrumpfschlauch zu verwendendes Produkt jedoch unerwünscht, da die Fäden sich beim späteren Verarbeitungsprozess, d.h. während des Schrumpfprozesses, noch gegeneinander verschieben sollen. Miteinander verklebte oder verschmolzene Fäden und Filamente können daher den abschließenden Schrumpfprozess des Hohlschlauchs auf dem zu umschrumpfenden Objekt beeinträchtigen.However, fusion or bonding of the filaments and filaments is undesirable for a product to be used as a shrink tubing, since the filaments may be lost during later processing, i. during the shrinking process, yet to shift against each other. Fused together or fused threads and filaments can therefore affect the final shrinkage process of the hollow tube on the object to be shrunk.
Die
Aus der
Die der Erfindung zugrunde liegende Problematik beruht darauf, dass ein flach aufgespulter textiler Schlauch abgespult und flach liegend orthogonal zur Längsrichtung in Abschnitte gleicher Länge geschnitten werden soll.The problem underlying the invention is based on the fact that a flat-wound textile hose unpacked and lying flat orthogonal to the longitudinal direction in sections of equal length to be cut.
Es wird ausgegangen von einem Schlauch, bestehend aus längs verlaufende, vorzugsweise aus Polyestermaterial bestehenden Multifilen (= Kettfäden) und quer, d.h. in Umfangsrichtung verlaufenden Monofilen (= Schussfaden = spätere Schrumpffäden).It is assumed that a hose consisting of longitudinally extending, preferably made of polyester material multifilaments (= warp threads) and transversely, i. in the circumferential direction running monofilaments (= weft thread = later shrink threads).
Die Multifil-Faserstränge haben die Eigenschaft, sich nach dem Schneiden aufzuspleißen. Die nebeneinander verlaufenden Multifil-Stränge, die den Monofil-Faden abwechselnd über- und unterlaufen, sind nicht miteinander verbunden. Bedingt durch den Web- und Aufspulprozess verläuft der Monofil-Strang im Gewebe in der Regel nicht orthogonal zur Schlauchlängsrichtung und nicht parallel zur Schnittkante und nicht geradlinig, sondern wellig/kurvig.The multifilament fiber strands have the property of splitting after cutting. The side-by-side multifilament strands, which alternately over- and under-run the monofilament, are not interconnected. Due to the weaving and winding process, the monofilament strand in the fabric generally does not run orthogonally to the tube longitudinal direction and not parallel to the cut edge and not straight, but wavy / curvy.
Wenn der Schlauch rechtwinklig zur Längsrichtung geschnitten wird, kann der Monifil-Faden ein bis mehrmals durchtrennt werden, so dass im Gewebe mehrere Monifil-Faden-Stücke vorliegen können. Der zur Längsrichtung quer verlaufende, verwebte Monofil-Faden ist an der seitlich und längs verlaufenden Naht einmal verknotet. Ansonsten wird der Monofil-Faden durch die Verflechtung/Verwebung mit den Multifil-Fasersträngen fest gehalten.If the tube is cut perpendicular to the longitudinal direction, the Monifil thread can be severed one to several times, so that there may be several Monifil thread pieces in the fabric. The longitudinally transverse, woven monofilament thread is knotted once at the side and longitudinal seam. Otherwise, the monofilament thread is held firmly by the entanglement / interweaving with the multifilament fiber strands.
Wird dieses Gewebe/Geflecht durch das orthogonal zur Schlaulängsrichtung verlaufende Schneiden aufgelöst, dann spleißen die elastischen Fäden der Multifil-Fasern auseinander und die nebeneinander liegenden und den Monofilfaden umschließenden Multifil-Faserstrände spreizen sich, so dass sich die Gewebestruktur und der Gewebeverband auflöst.When this tissue / braid is disintegrated by the cutting orthogonal to the crawl longitudinal direction, the elastic threads of the multifilament fibers splice and the multifilament fiber strands adjoining each other and surrounding the monofilament threads spread, dissolving the tissue structure and the tissue structure.
Dadurch kann sich der Monofil-Faden aus dem Gewebeverband lösen, so dass kurze Teilstücke des Monofil-Fadens an der Schnittkante herausfallen. Diese Schnittstücke verursachen Probleme und müssen verhindert oder entfernt werden.As a result, the monofilament thread can be released from the woven fabric, so that short sections of the monofilament thread fall out of the cut edge. These cuts cause problems and must be prevented or removed.
Durch das Öffnen der Multifil-Fasern und -Faserstränge franst die Schnittkante des Schlauches aus, was vermieden werden muss.By opening the multifilament fibers and fiber strands fringes the cutting edge of the hose, which must be avoided.
Die Erfindung geht aus von einem Verfahren gemäß dem Oberbegriff des Patentanspruchs 1.The invention is based on a method according to the preamble of patent claim 1.
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber den bekannten Verfahren verbessertes Verfahren zu schaffen, um zu erreichen, dass die Fäden im Bereich der Schlauchenden für den späteren Verarbeitungs- bzw. Schrumpfprozess ausreichend konditioniert sind.The invention has for its object to provide a comparison with the known methods improved method to achieve that the threads are sufficiently conditioned in the region of the hose ends for the subsequent processing or shrinking process.
Zur Lösung dieser Aufgabe dienen die Merkmale des Kennzeichens von Anspruch 1.To solve this problem, the features of the characterizing part of claim 1 serve.
Die Pressbacken, die die Monofil-Fäden halten, so dass der Schlauch nicht schrumpft, pressen auch die Fäden der jeweils unteren und oberen Schlauchlagen ineinander, so dass die Fäden sich verhaken. Damit diese durch Kaltverpressen entstandenen Verhakungen = Retentionen sich nicht wieder lösen, müssen die Fäden bzw. Fasern ausreichend erwärmt werden, so dass die plastische Verformung der ineinander verpressten Fasern und die dadurch entstandenen Retentionen bedingt haltbar werden.The pressing jaws, which hold the monofilament threads so that the tube does not shrink, also press the threads of the respective lower and upper tube layers into each other so that the threads become entangled. So that these entanglements created by cold pressing = retention If they do not come loose again, the threads or fibers must be heated sufficiently, so that the plastic deformation of the fibers pressed into each other and the resulting retention are conditionally preserved.
Nach dem Verpressen des Gewebes muss das aus Kunststofffasern bestehende Gewebe abkühlen, so dass die Verpressung und die Retentionen bedingt dauerhaft haltbar werden.After the tissue has been pressed, the tissue consisting of synthetic fibers must cool down, so that the compression and the retention become conditionally durable.
Da bei dem Schlauch zwei Schlauch- bzw. Gewebelage übereinander liegen, die sich nicht bleibend miteinander verhaken dürfen (nur die Fasern jeder einzelnen Schlauch- bzw. Gewebelage dürfen sich verhaken), müssen beiden Lagen voneinander getrennt werden. Das Trennelement ist vorzugsweise wärmeleitend, muss hitzebeständig sein und darf sich nicht zersetzen, darf keinen Druck aufnehmen und der erweichte Kunststoff darf nicht daran haften.Since the hose has two layers of hose or fabric that are not allowed to get stuck together (only the fibers of each individual hose or fabric layer may get caught), both layers must be separated from each other. The separating element is preferably thermally conductive, must be heat-resistant and must not decompose, it must not absorb pressure and the softened plastic must not adhere to it.
Das Trennelement kann entweder im Anschluss an die Wärmebehandlung oder während der Wärmebehandlung im Wärmebehandlungsgerät wirksam sein.The separator may be effective either following the heat treatment or during the heat treatment in the heat treatment apparatus.
Das Pressen, das Erwärmen, das Abkühlen und das Schneiden in der Mitte des gepressten Bereiches muss schnell erfolgen, da das Verfahren für eine Serienteilfertigung mit hoher Taktfrequenz und Menge taugen soll.The pressing, heating, cooling and cutting in the middle of the pressed area must be done quickly, since the process for a series part production with high clock frequency and quantity is good.
Der problematische Verlauf der Monofil-Fäden lässt sich vorzugsweise durch abwechselndes Recken/Strecken und Entspannen rechwinklig zur Längsrichtung korrigieren, so dass beim Schneiden weniger Monofil-Faden-Stücke entstehen und die nach dem Schneiden entstandene Schnittkante weniger zum Ausfransen neigt.The problematic course of the monofilament threads can preferably be corrected by alternating stretching / stretching and relaxing at right angles to the longitudinal direction, so that fewer monofilament thread pieces are formed during cutting and the cut edge resulting after cutting is less susceptible to fraying.
Vorzugsweise wird ein Schlauch verwendet, dessen in Umfangsrichtung verlaufenden Fäden, insbesondere die Schussfäden, strahlungsvernetze Polyolefinfäden sind.Preferably, a hose is used whose circumferentially extending threads, in particular the weft threads, are radiation-crosslinked polyolefin threads.

Die erfindungsgemäß verwendete Maschine überträgt die Ultraschallenergie vorzugsweise mittels einer auf- und abbewegbaren Sonotrode 3, der als Wiederlager ein Amboss 4 gegenüberliegt. Diesem Wärmebehandlungsgerät 3, 4 wird in Richtung des Pfeiles f1 ein Schlauch 2 zugeführt, der im Bereich der Stufe (a) zu zwei flächig übereinanderliegenden unteren und oberen Lagen 2.1, 2.2 zusammengelegt ist. Im Bereich der Stufe (b) des Wärmebehandlungsgerätes 3, 4 werden die Fäden der beiden Schlauchlagen 2.1 und 2.2 soweit erwärmt, dass die Gewebefäden unter Druckanwendung warm verformt und sich im Pressbereich "y" jeder der beiden Schlauchlagen bedingt haltbar ineinander verpressen bzw. verhaken.The machine used according to the invention preferably transmits the ultrasound energy by means of a sonotrode 3 which can be moved up and down, which as an abutment lies opposite an
Der Begriff "bedingt haltbar ineinander verpresst" entspricht damit nicht einem "dauerhaften haltbaren Verschmelzen" der Gewebefäden.The term "conditionally durable pressed into each other" thus does not correspond to a "durable durable fusion" of the fabric threads.
Um zu verhindern, dass die Fäden der beiden unteren und oberen Gewebelagen 2.1 und 2.2 bleibend miteinander verhakt bleiben, folgt gemäß einer ersten Ausführungsform der Erfindung auf das Wärmebehandlungsgerät 3, 4 ein vorzugsweise aus Metall bestehendes Trennelement 11, vorzugsweise in Form einer Kugel oder eines Walzenkörpers. Auf dieses Trennelement 11 folgt eine Trennelement-Rückhaltevorrichtung, bestehend aus einer vorzugsweise stationären Walze 14 und einer damit zusammenwirkenden, auf- und abbewegbaren Walze 13. Das Trennelement 11 wird zu Beginn eines Verfahrenszyklusses hinter dem Wärmebehandlungsgerät 3, 4 in das offene vorlaufende Schlauchende eingeführt, wobei die Trennelement-Rückhaltevorrichtung 13, 14 geöffnet wird, indem die obere bewegliche Walze 13 soweit angehoben wird, dass das Trennelement 11 in den Schlauch eingeschoben werden kam. Das vorzugsweise aus Metall bestehende Trennelement 11 hat entweder die Form einer Kugel oder eines Walzenkörpers mit sich vorzugsweise zu den Walzenenden hin verjüngenden Querschnitten und abgerundeten Enden. Die unteren und oberen Schlauchlagen 2.1 und 2.2 werden mittels des Trennelementes 11 im Anschluss an die Wärmebehandlungs- und Pressstufe (B) voneinander getrennt bzw. von einander abgehoben, bevor der Schlauch 2 von den Walzen 13, 14 einer die dritte Stufe "a" bildenden Schneidvorrichtung zugeführt, die gemäß
