Description

Gegenstand der Erfindung ist eine Vorrichtung zum Entnadeln einer Warenbahn gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a device for Needling a web according to the preamble of Patent claim 1.

Bei der Veredelung von textilen Warenbahnen, insbesondere von gewirkten, geraschelten sowie gestrickten Textilien und auch bei Vliesstoffen wird die Warenbahn auf einem Spannrahmen entlang ihrer Längskanten durch Nadeln festgehalten. Am Ende des Spannrahmens muss die Warenbahn möglichst sorgfältig aus der Benadelung, welche üblicherweise an umlaufenden Transportbändern ausgebildet ist, entnommen werden. Die Entnahme kann durch keilförmig angeordnete in einem spitzen Winkel zur Warenbahn liegende und parallel zu den benadelten Bändern verlaufende Schienen erfolgen, welche die Warenbahn sukzessive aus der Benadelung abheben. Da in einem Spannrahmen am Ende des Durchlaufs der Materialbahn letztere meist zwischen den Nadeln gespannt gehalten wird, kann es beim Entnadeln zu Beschädigungen der Ränder der Materialbahn kommen, sobald diese nicht mehr vollständig von den Nadeln durchdrungen gehalten wird. In the finishing of textile webs, in particular knitted, knitted and knitted textiles and also in nonwovens, the web is on a Tenter frame along its longitudinal edges by needles recorded. At the end of the tenter the web must as carefully as possible from the Benadelung, which usually formed on rotating conveyor belts is to be taken. The removal may be by wedge-shaped arranged at an acute angle to the web lying and running parallel to the needled ribbons Rails take place, which successively from the Take out nobility. As in a tenter at the end of the Pass the material web latter usually between the Needles is kept taut, it can when peeling too Damage to the edges of the web come as soon as these are no longer completely penetrated by the needles is held.

Eine Aufgabe der vorliegenden Erfindung ist die Schaffung einer Vorrichtung zum Entnadeln einer Warenbahn, bei der die Warenbahn während des Entnadelns durch die Nadeln keine Schädigung erleidet.An object of the present invention is the creation a device for needling a web, in the the web during needling through the needles does not suffer damage.

Gelöst wird diese Aufgabe durch eine Vorrichtung gemäss den Merkmalen des Patentanspruchs 1. Vorteilhafte Ausgestaltungen der Vorrichtung sind in den abhängigen Ansprüchen definiert.This object is achieved by a device according to the features of claim 1. Advantageous Embodiments of the device are in the dependent Claims defined.

Mit der erfindungsgemässen Vorrichtung wird die Warenbahn während der Entnadelung und, sofern erwünscht, auch danach kontrolliert gehalten. Es können die von der Warenbahn quer zur Transportrichtung wirkenden Spannkräfte während der Entnadelung temporär von der Vorrichtung übernommen werden. Die Vorrichtung ermöglicht weiter eine kontrollierte Übergabe an das nachfolgende Transportmittel, sei es nun ein mit gleicher Geschwindigkeit laufendes Transportband oder ein Transportband mit geringerer Geschwindigkeit, um die Warenbahn zu stauchen und um der Warenbahn Gelegenheit zum Schrumpfen (Relaxen) zu geben.With the inventive device is the web during the needle-punching and, if desired, afterwards kept controlled. It can be from the web clamping forces acting transversely to the transport direction the needling temporarily taken from the device become. The device further allows one controlled transfer to the following one Means of transport, be it one with the same Speed running conveyor belt or one Conveyor belt at a lower speed to the Web to upsetting and the web opportunity to To give shrinking (relaxing).

In Figur 1 ist, durch ein Trapez dargestellt, ein Spannrahmen 1 mit zwei für den Warentransport bestimmten Spannrahmen-Ketten mit Nadelplatten 3 sichtbar. Die Spannrahmen-Ketten mit Nadelplatten 3 laufen endlos um Umlenkrollen 5,7 um und werden durch einen Motor M angetrieben. Zwischen den Umlenkrollen 5,7 sind die oberen Trume der Spannrahmen-Ketten 3 auf Gleitflächen 9 abgestützt. Die beiden Spannrahmen-Ketten 3 verlaufen im dargestellten Beispiel divergierend. Einlaufseitig an der Warenaufnahmestelle A liegen die beiden Spannrahmen-Ketten 3 folglich näher beieinander als an der Warenabgabestelle B. Die Ausbildung des Spannrahmens 1, wie er schematisch in den Zeichnungen dargestellt ist, wird nicht näher erläutert, da er aus dem Stand der Technik bekannt ist.In Figure 1, represented by a trapezoid, a Clamping frame 1 with two intended for the transport of goods Tenter chains with needle plates 3 visible. The Tenter chains with needle plates 3 are endless Pulleys 5.7 um and are powered by a motor M driven. Between the pulleys 5.7 are the upper Trume of the tenter chains 3 on sliding surfaces 9 supported. The two tenter chains 3 run in diverging example illustrated. On the inlet side at the Goods receiving point A are the two tenter chains 3 therefore closer together than at the goods delivery point B. The formation of the clamping frame 1, as shown schematically is shown in the drawings, does not get closer because it is known from the prior art.

Im Bereich der Warenbahnabgabestelle B ist zwischen den beiden Spannrahmen-Ketten 3 unmittelbar benachbart dazu je ein Transportmittel 11 angeordnet. Die beiden Transportmittel 11 können parallel zu den benachbarten Spannrahmen-Ketten 3 verlaufend angeordnet sein oder mit diesen einen spitzen Winkel beta einschliessen. Als Transportmittel werden vorzugsweise um mindestens zwei Umlenkrollen 13,15 umlaufende endlose Förderbänder oder -riemen 19 eingesetzt. Vorzugsweise ist zwischen den beiden Umlenkrollen 13,15 eine Auslenkrolle 17 eingesetzt, welche das obere Trum des auf den Umlenkrollen 13,15 umlaufenden Förderbandes 19 in zwei Trumabschnitte 19' und 19" unterteilt. Das untere Trum 19'" kann durch eine Stützrolle 21 ebenfalls nach oben ausgelenkt sein, sofern dies aus konstruktiven Gründen notwendig ist. Die Förderbänder 19 sind durch einen nicht dargestellten Motor, vorzugsweise ein Servomotor, antreibbar.
Über den Förderbändern 19 laufen je ein endloses Klemmband 23 über mindestens zwei Umlenkrollen 25,27 um. Deren untere Trume 23' liegen sowohl am Trumabschnitt 19' als auch am Trumabschnitt 19" auf und erfahren dadurch eine Umlenkung. Das obere Trum 23' kann, falls nötig, durch eine Auslenkrolle 29 angehoben werden.
Alternativ können auch an die Stelle von durch Auslenkrollen ausgelenkten Förderbändern je versetzt zueinander verlaufend Förderbänder eingesetzt werden, deren Trum den gewünschten Winkel einnehmen.
An der Stelle X schneidet das obere Trum 19' des Transportbandes 19 die Ebene E, in welcher die oberen Trume der Spannrahmen-Ketten 3 umlaufen im dargestellten Beispiel in einem spitzen Winkel alpha. Der Kreuzungswinkel zwischen der Ebene E und dem oberen Trum 19' kann bis zu 90° betragen.
Das Transportmittel 11, umfassend das Transportband 19 und das Klemmband 23 überragen den Warenbahnübergabebereich A und ragen zudem über ein an den Spannrahmen 1 anschliessendes Fördersystem 33. Dieses kann beispielsweise ein um Umlenkrollen 35 umlaufendes Band, Netz oder Gitter 37 sein, auf dem eine den Spannrahmen 1 durchlaufende Warenbahn 39 abgeführt wird.In the area of the web delivery point B, a respective transport means 11 is arranged immediately adjacent to each of the two clamping frame chains 3. The two transport means 11 may be arranged to extend parallel to the adjacent tenter frame chains 3 or enclose with these an acute angle beta. As a means of transport are preferably around at least two pulleys 13,15 circulating endless conveyor belts or belts 19 used. Preferably, a deflection roller 17 is inserted between the two deflection rollers 13, 15, which subdivides the upper run of the conveyor belt 19 circulating on the deflection rollers 13, 15 into two shoulder sections 19 'and 19 "The lower run 19'" can likewise be replaced by a support roller 21 be deflected upward, if this is necessary for design reasons. The conveyor belts 19 are driven by a motor, not shown, preferably a servo motor.
About the conveyor belts 19 each run an endless clamping belt 23 via at least two pulleys 25,27. Their lower strands 23 'rest both on the runner section 19' and on the runner section 19 '' and thereby undergo a deflection, The upper run 23 'can, if necessary, be lifted by a deflection roller 29.
Alternatively, it is also possible to use conveyor belts which are offset from one another by conveyor belts deflected by deflection rollers, and whose conveyor belts occupy the desired angle.
At the point X, the upper run 19 'of the conveyor belt 19 intersects the plane E, in which the upper strands of the tensioning frame chains 3 rotate in the example shown at an acute angle alpha. The crossing angle between the plane E and the upper run 19 'can be up to 90 °.
The transport 11, comprising the conveyor belt 19 and the clamping belt 23 project beyond the web transfer area A and also protrude via a subsequent to the clamping frame 1 conveyor system 33. This may be, for example, a circulating rollers 35 circulating belt, mesh or grid 37, on which a tenter 1 continuous web 39 is discharged.

Nachfolgend wird die Funktionsweise der Vorrichtung näher erläutert. In den Figuren wird von links die Warenbahn 39 in bekannter Weise zum Spannrahmen 1 geführt und entlang deren Kanten mit den Spannrahmen-Ketten 3 verbunden. Von den beiden Spannrahmen-Ketten 3, welche synchron angetrieben werden, wird die Materialbahn 39 im Beispiel eines divergierenden Spannrahmens 1 sukzessive quer zur Transportrichtung T auseinandergezogen. Kurz vor Erreichen der Warenbahnabgabestelle B gelangen die Kantenbereiche der Warenbahn 39 in Kontakt mit den Transportbändern 19 des Transportmittels 11. Infolge der in spitzem Winkel alpha nach oben verlaufenden Trume 19' der Transportbänder 19 werden die Ränder der Warenbahn 39 sukzessive angehoben und aus den Nadeln der Spannrahmen-Ketten 3 herausgeführt und damit die Verbindung zu den Nadelbändern 3 gelöst. Während des Herausführens der Warenbahnkanten wird die Warenbahn 39 vom unteren Trum 23' des Klemmbandes 23 an den Trumabschnitt 19' des Transportbandes 19 angepresst und damit festgehalten bzw. festgeklemmt. Die Klemmung der Warenbahn 39 beim Entnadeln hebt die Spannkräfte, welche durch das Dehnen der Warenbahn 39 im Spannrahmen 1 erzeugt worden sind, auf und verhindert, dass von den Nadeln Fasern aus der Oberfläche der Unterseite der Warenbahn 39 herausgezogen werden.
Besonders vorteilhaft erweist sich die Führung der Förderbänder 19 und Klemmbänder 23 in einem spitzen Winkel beta zur Transportrichtung der Spannrahmen-Ketten 3. Durch diese Massnahme wird die Warenbahn 39 während des Entnadelns durch die genannten Bänder weiter quer zur Transportrichtung T gestreckt und damit die Zugkräfte auf die Nadeln an den Spannrahmen-Ketten 3 vollständig aufgehoben.The operation of the device will be explained in more detail below. In the figures, the web 39 is guided from the left in a known manner to the clamping frame 1 and connected along the edges thereof with the tenter chains 3. Of the two clamping frame chains 3, which are driven synchronously, the material web 39 is pulled apart in the example of a divergent clamping frame 1 successively transversely to the transport direction T. Shortly before reaching the web delivery point B reach the edge portions of the web 39 in contact with the conveyor belts 19 of the transport 11. As a result of the acute angle alpha upwardly extending strands 19 'of the conveyor belts 19, the edges of the web 39 are successively raised and from the needles Tensioning frame chains 3 led out and thus solved the connection to the needle bands 3. During the lead-out of the web edges, the web 39 is pressed from the lower run 23 'of the clamping band 23 to the run portion 19' of the conveyor belt 19 and thus held or clamped. The clamping of the web 39 during needling raises the clamping forces which have been generated by the stretching of the web 39 in the clamping frame 1, and prevents fibers from the needles from being pulled out of the underside surface of the web 39.
Particularly advantageously, the leadership of the conveyor belts 19 and clamping straps 23 turns at an acute angle beta to the transport direction of the tenter chains 3. By this measure, the web 39 is further extended transversely to the transport direction T during the needling by said bands and thus the tensile forces the needles on the tenter chains 3 completely eliminated.

Die geführte Entnadelung der Warenbahn 39 vom Spannrahmen 1 ermöglicht es, die freigegebene Warenbahn 39 auf ein nachfolgendes Fördersystem 33 abzulegen, dessen Fördergeschwindigkeit v2 beispielsweise geringer sein kann als die Fördergeschwindigkeit v1 der Spannrahmen-Ketten 3, um der Materialbahn 39 Gelegenheit zum Schrumpfen/Relaxen zu geben. Die Fördergeschwindigkeit des Förderbandes 19 und des Klemmbandes 23 kann ebenfalls bezüglich der Geschwindigkeit v1 der Spannrahmen-Ketten 3 differieren, um die Entnadelung zu begünstigen.The guided needling of the web 39 from the clamping frame 1 makes it possible to deposit the released web 39 on a subsequent conveyor system 33, the conveying speed v 2 may be, for example, lower than the conveying speed v 1 of the tenter chains 3 to the material web 39 opportunity for shrinking / To give relax. The conveying speed of the conveyor belt 19 and the clamping band 23 may also differ with respect to the speed v 1 of the tenter chains 3 in order to favor the needling.
