Description

Die Erfindung betrifft eine Kratzenrauhmaschine für textile Warenbahnen.The invention relates to a scraping machine for textile webs.

Mit einer Kratzenrauhmaschine wird die Oberfläche der textilen Warenbahn aufgerauht (Rauheffekt) und somit insbesondere ein erhöhtes Wärmehaltungsvermögen und ein wolliger, flauschiger Griff erzielt. Zur Erreichung eines Rauheffektes ist eine Relativgeschwindigkeit (Differenzgeschwindigkeit) zwischen der Umfangsgeschwindigkeit der angetrieben Kratzenwalzen (Gegenstrichwalzen und/oder Strichwalzen) und der Geschwindigkeit der zu rauhenden textilen Warenbahn erforderlich.The surface of the textile web is roughened with a scratch roughening machine (rough effect) and thus, in particular, increased heat retention and a woolly, fluffy feel. To achieve a roughening effect, a relative speed (differential speed) between the peripheral speed of the driven scraping rollers (counter-coating rollers and / or line rollers) and the speed of the textile fabric web to be roughened is required.

Es ist bereits eine Kratzenrauhmaschine bekannt (DE-OS 39 23 611), bei der im Tambour mehrere mit Kratzenwalzen bestückte Rauhwalzeneinheiten angeordnet sind. Entsprechend einer Ausführungsform weisen diese Rauhwalzeneinheiten in beiderends vorgesehenen Aufnahmen jeweils zwei Kratzenwalzen der einen Walzenart und eine Kratzenwalze der anderen Walzenart auf. Damit ist es möglich, durch das Drehen und anschließende Arretieren der Rauhwalzeneinheiten das Verhältnis von Gegenstrichwalzen zu Strichwalzen zu ändern, beispielsweise von 1 : 1 auf 3 : 1, wenn in jeder Rauhwalzeneinheit zwei Gegenstrichwalzen und eine Strichwalze gelagert sind, oder nur mit Gegenstrichwalzen zu rauhen. Bei dieser Lösung sind jedoch nur die sich in Arbeitsstellung befindenden Kratzenwalzen angetrieben, was bei einer Änderung des Verhältnisses von Gegenstrichwalzen zu Strichwalzen und der damit verbundenen Schaffung des erforderlichen Antriebes der sich nunmehr in Arbeitsstellung befindenden Kratzenwalzen zu einem reletav hohen Aufwand führt.A scraper roughening machine is already known (DE-OS 39 23 611), in which a plurality of scraper roller units equipped with scraper rollers are arranged in the drum. According to one embodiment, these roughing roller units each have two scraping rollers of one type of roller and one scraping roller of the other type of roller in the receptacles provided at both ends. This makes it possible to change the ratio of counter-coating rollers to coating rollers, for example from 1: 1 to 3: 1, if two counter-coating rollers and one coating roller are stored in each coating roller unit, or only to be roughened with counter-coating rollers by rotating and then locking the cleaning rollers . With this solution, however, only the scraping rollers in the working position are driven, which results in a change in the ratio from counter-coating rollers to coating rollers and the associated creation of the required drive of the scraping rollers now in the working position leads to a relatively high outlay.

Hier will die Erfindung Abhilfe schaffen, mit dem Ziel, den Aufwand für das Ändern des Verhältnisses von der einen zu der anderen Art von Kratzenwalzen zu verringern.The invention aims to remedy this, with the aim of reducing the effort for changing the ratio of one to the other type of scraping rollers.

Der Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Kratzenrauhmaschine zu schaffen, bei der sämtliche in jeder Rauhwalzeneinheit gelagerten Kratzenwalzen angetrieben werden.The invention, as characterized in the claims, solves the problem of creating a scraper roughing machine in which all scraper rolls mounted in each roughing roll unit are driven.

Durch die erfindungsgemäße Lösung ist es möglich, relativ schnell einen Wechsel des Verhältnisses der einen zu der anderen Art von Kratzenwalzen vornehmen zu können.The solution according to the invention makes it possible to be able to change the ratio of one to the other type of scraper rollers relatively quickly.

Im folgenden wird die Erfindung anhand lediglich eines Ausführungsbeispieles näher erläutert. In der dazugehörigen Zeichnung zeigt

The invention is explained in more detail below with the aid of only one exemplary embodiment. In the accompanying drawing shows

Wie aus Fig. 1 und Fig. 2 zu entnehmen ist, besitzt der zur Kratzenrauhmaschine gehörende Tambour im wesentlichen eine in den Lagerstellen 1 des Maschinengestells gelagerte Tambourwelle 2 mit zwei Tambourscheiben 3 und einem Tambourantriebsgetriebe 4 sowie an der Peripherie der Tambourscheiben 3 mehrere gelagerte Rauhwalzeneinheiten 5. Zu jeder Rauhwalzeneinheit 5 gehören unter anderem zwei Aufnahmen 5.1, in denen drei angetriebene Kratzenwalzen 6 - zwei Gegenstrichwalzen 6.1 und eine Strichwalze 6.2 - gelagert sind. Bei beispielsweise einer Kratzenrauhmaschine mit vierundzwanzig sich in Arbeitsstellung befindenden Kratzenwalzen 6 (Fig. 1) ist der Tambour mit zwölf Rauhwalzeneinheiten 5 und bei einer Kratzenrauhmaschine mit zweiunddreißig sich in Arbeitsstellung befindenden Kratzenwalzen 6 ist der Tambour mit sechzehn Rauhwalzeneinheiten 5 bestückt. Als die sich in Arbeitsstellung befindenden Kratzenwalzen 6 werden diejenigen betrachtet, die sich auf dem Teilkreis 6.3 befinden. Aus Gründen der Übersichtlichkeit wurde auf die Darstellung weiterer zur Kratzenrauhmaschine gehörender Baugruppen, wie Gestell, Warenbahnführung etc. verzichtet. Ebenfalls wurden aus Gründen der übersichtlichkeit von den in der Kratzenrauhmaschine vorhandenen Rauhwalzeneinheiten 5 in Fig. 2 lediglich zwei gezeigt, und zwar, um einmal den Antrieb der Gegenstrichwalzen 6.1 - rechte Seite der Fig. 2 - und zum anderen den Antrieb der Strichwalzen 6.2 - linke Seite der Fig. 2 - übersichtlicher darstellen zu könkönnen, wobei von der in Fig. 1 gezeigten Anordnung der Rauhwalzeneinheiten 5 in Fig. 2 abgewichen wurde.As can be seen from FIGS. 1 and 2, the spool belonging to the scraping machine essentially has a spool shaft 2, which is mounted in the bearing points 1 of the machine frame, with two spool discs 3 and a spool drive 4, as well as a plurality of nested roller units 5 on the periphery of the spool discs 3 Each pick-up roller unit 5 includes, among other things, two receptacles 5.1, in which three driven scraper rollers 6 - two counter-coating rollers 6.1 and one coating roller 6.2 - are mounted. For example, in a scraper roughening machine with twenty four scraper rollers 6 (FIG. 1) in the working position, the reel is equipped with twelve scraper roller units 5, and in a scraper roughening machine with thirty two scraper rollers 6 in the working position, the reel is equipped with sixteen roughing roller units 5. The scraping rollers 6 in the working position are considered to be those located on the pitch circle 6.3. For the sake of clarity, no other components belonging to the scraper roughing machine, such as the frame, web guide, etc. have been shown. Likewise, for reasons of clarity, only two of the roughing roller units 5 present in the scraper roughing machine were shown in FIG. 2, namely in order to drive the counter-coating rollers 6.1 - right side of FIG. 2 - and on the other hand to drive the line rollers 6.2 - left Side of FIG. 2 - to be able to represent in a clearer manner, wherein the arrangement of the roughing roller units 5 in FIG. 2 shown in FIG. 1 was deviated from.

In den folgenden Darlegungen zum Ausführungsbeispiel wird dabei auf den Antrieb dieser in Fig. 2 gezeigten Kratzenwalzen 6 eingegangen. Für die übrigen Rauhwalzeneinheiten 5 liegt die Analogie zu den beiden gezeigten Rauhwalzeneinheiten 5 und den darin gelagerten Kratzenwalzen 6 einschließlich ihres Antriebes vor. Es sei ferner darauf verwiesen, daß von den zwei Gegenstrichwalzen 6.1 und der einen Strichwalze 6.2 pro Rauhwalzeneinheit 5 in der oberen in Fig.2 dargestellten Rauhwalzeneinheit 5 lediglich zwei Gegenstrichwalzen 6.1 und in der unteren in dieser Fig. 2 dargestellten Rauhwalzeneinheit 5 lediglich eine Gegenstrichwalze 6.1 und eine Strichwalze 6.2 eingezeichnet sind.In the following explanations of the exemplary embodiment, the drive of the scraping rollers 6 shown in FIG. 2 is discussed. For the other roughing roller units 5 there is an analogy to the two shown roughing roller units 5 and the scraping rollers 6, including their drive, mounted therein. It should also be pointed out that of the two counter-coating rollers 6.1 and the one coating roller 6.2 per roughing roller unit 5, only two counter-coating rollers 6.1 in the upper roughing roller unit 5 shown in FIG. 2 and only one counter-coating roller 6.1 in the lower leveling roller unit 5 shown in FIG. 2 and a line roller 6.2 are shown.

An der Peripherie der beiden Tambourscheiben 3 befinden sich Lagerstellen 7 fuer die Aufnahmen 5.1. In diesen Lagerstellen 7 sind die Rauhwalzeneinheiten 5 gemeinsam oder getrennt voneinander schwenkbar und durch jeweils eine Arretiervorrichtung 8 gegenüber der (den) Tambourscheibe(n) 3 in ihrer Lage fixierbar. Durch das Schwenken der Rauhwalzeneinheiten 5 ist es möglich, das Verhältnis von sich in Arbeitsstellung befindenden Gegenstrichwalzen 6.1 zu Strichwalzen 6.2 zu ändern, wie es beispielsweise aus der nachstehenden Aufstellung ersichtlich ist.

Figure imgb0001
On the periphery of the two reel disks 3 there are bearing points 7 for the receptacles 5.1. In these bearing points 7, the roughing roller units 5 can be swiveled together or separately from one another and can be fixed in position by means of a locking device 8 relative to the drum disk (s) 3. By pivoting the roughing roller units 5, it is possible to change the ratio of the counter-coating rollers 6.1 in the working position to the line rollers 6.2, as can be seen, for example, from the list below.
Figure imgb0001

Jede Kratzenwalze 6 besitzt zu ihrer Lagerung in den Lagerstellen 5.11 der Aufnahmen 5.1 beiderends je einen Zapfen, und zwar die Gegenstrichwalze 6.1 den Antriebszapfen 6.11 auf der einen Seite und den Zapfen 6.12 auf ihrer Gegenseite und die Strichwalze 6.2 den Antriebszapfen 6.21 auf der einen Seite und den Zapfen 6.22 auf ihrer Gegenseite. Ferner befinden sich auf den Antriebszapfen 6.11 und 6.21 fest angeordnete Riemenscheiben 9 sowie auf dem Zapfen 6.12 einer der beiden in jeder Rauhwalzeneinheit 5 gelagerten Gegenstrichwalzen 6.1 eine lose mitlaufende Riemensscheibe 10.Each scraper roller 6 has a pin for its storage in the bearing points 5.11 of the receptacles 5.1, namely the counter-stroke roller 6.1, the drive pin 6.11 on one side and the pin 6.12 on its opposite side and the line roller 6.2 the drive pin 6.21 on the one side and the pin 6.22 on its opposite side. There are also fixed pulleys 9 on the drive journals 6.11 and 6.21 and on the journals 6.12 of one of the two counterstroke rollers 6.1 mounted in each roughing roller unit 5 there is a loose pulley 10.

In jeder Aufnahme 5.1 der Rauhwalzeneinheiten 5 ist jeweils eine Welle 11 gelagert. Auf jeder Welle 11 befindet sich eine für den Antrieb der Welle 11 dienende Riemenscheibe 12 und eine für den Antrieb der Kratzenwalzen 6 dienende Riemenscheibe 13. Die antriebsseitige Verbindung von den Antriebsscheiben 14 zu den Riemenscheiben 12 erfolgt durch einen Riementrieb 15 und zwischen den Riemenscheiben 13 und den auf den Antriebszapfen 6.11 und 6.21 der Rauhwalzen 6 angeordneten Riemenscheiben 9 durch Riementriebe 16.A shaft 11 is mounted in each receptacle 5.1 of the roughing roller units 5. On each shaft 11 there is a pulley 12 which drives the shaft 11 and a pulley 13 which drives the scraper rollers 6. The drive-side connection from the drive pulleys 14 to the pulleys 12 takes place by means of a belt drive 15 and between the pulleys 13 and the pulleys 9 arranged on the drive pins 6.11 and 6.21 of the roughing rollers 6 by means of belt drives 16.

In Fig. 3 ist der Antrieb der in einer Rauhwalzeneinheit 5 gelagerten Gegenstrichwalzen 6.1 dargestellt. Hierbei umschließt ein erster Riementrieb 16 jeweils die auf der Welle 11 und die auf den Antriebszapfen 6.11 der beiden Gegenstrichwalzen 6.1 angeordneten Riemenscheiben 9 auf einem Teil ihres Umfanges.FIG. 3 shows the drive of the counter-coating rollers 6.1, which are mounted in a roughing roller unit 5. Here, a first belt drive 16 encloses each on the shaft 11 and the pulleys 9 arranged on the drive journal 6.11 of the two counter-coating rollers 6.1 over part of their circumference.

Der Antrieb der in der Rauhwalzeneinheit 5 gelagerten Strichwalzen 6.2 (Fig. 4) erfolgt über einen zweiten Riementrieb 16, der die auf der anderen Welle 11 der Rauhwalzeneinheit 5 fest angeordnete Riemenscheibe 13 und die auf dem Antriebszapfen 6.21 der Strichwalze 6.2 fest angeordnete Riemenscheibe 9 und die auf dem Zapfen 6.12 der Gegenstrichwalze 6.1 lose mitlaufende Riemenscheibe 10 auf einem Teil ihres Umfanges umschließt.The line rollers 6.2 (FIG. 4) mounted in the surface roller unit 5 are driven via a second belt drive 16, which has the belt pulley 13 fixedly arranged on the other shaft 11 of the surface roller unit 5 and the belt pulley 9 and fixedly arranged on the drive pin 6.21 of the line roller 6.2 the belt pulley 10 which loosely runs on the journal 6.12 of the counter-coating roller 6.1 over part of its circumference.

Wie aus Fig. 3 und Fig. 4 hervorgeht, umschließen die Riementriebe 16 in jeder Rauwalzeneinheit 5 sowohl beim Antrieb der Gegenstrichwalzen 6.1 wie auch beim Antrieb der Strichwalze 6.2 jeweils drei Riemenscheiben 9, 9 und 13 (Antrieb der Gegenstrichwalzen 6.1) beziehungsweie 9, 10 und 13 (Antrieb der Strichwalze 6.2).As can be seen from FIGS. 3 and 4, the belt drives 16 in each roughing roller unit 5 each encompass three pulleys 9, 9 and 13 (drive of the counter-coating rollers 6.1) and 9, 10 both when driving the counter-coating rollers 6.1 and when driving the coating roller 6.2 and 13 (drive of the line roller 6.2).

Die Kratzenrauhmaschine arbeitet wie folgt:
Die textile Warenbahn 18 wird durch eine am Eingang und eine weitere am Ausgang der Kratzenrauhmaschine angeordnete Zugwalze 17 über den Tambour geführt und aufgrund der zwischen der Tranportgeschwindigkeit der textilen Warenbahn 18 und der Umfangsgeschwindigkeit der sich in Arbeitsstellung befindenden Kratzenwalzen 6 vorhandenen Relativgeschwindigkeit (Differenzgeschwindigkeit) gerauht. Die Differenzgeschwindigkeit wird dabei durch den Antrieb der Kratzenwalzen 6 wie auch durch die Rotationsbewegung des Tambours beeinflußt. Die Bewegungsrichtung der textilen Warenbahn 18 ist in Fig. 1, 3 und 4 durch Pfeile dargestellt. Dieses trifft auch auf die in Fig. 1 gezeigte Drehrichtung des Tambours zu, wobei der Pfeil mit der unterbrochenen Linie die Drehrichtung des Tambours beim sogenannten Gegenrauhen darstellt.
The scraper roughing machine works as follows:
The textile web 18 is guided over the reel by a pulling roller 17 arranged at the entrance and another at the exit of the scraper roughing machine and roughened due to the relative speed (differential speed) between the transport speed of the textile web 18 and the peripheral speed of the scraping rollers 6 in the working position. The differential speed is influenced by the drive of the scraper rollers 6 as well as by the rotational movement of the drum. The direction of movement of the textile web 18 is shown in Fig. 1, 3 and 4 by arrows. This also applies to the direction of rotation of the drum shown in FIG. 1, the arrow with the broken line representing the direction of rotation of the drum during the so-called counter-roughening.

Die Kratzenwalzen 6 werden wie folgt angetrieben:
Für den Antrieb der Gegentrichwalzen 6.1 und den der Strichwalzen 6.2 ist jeweils zwischen der Riemenscheibe 14 und den Riemenscheiben 12 eine kraftschlüssige Leistungsübertragung durch einen Riementrieb 15 zu den in den Aufnahmen 5.1 gelagerten Wellen 11 vorhanden. Zwischen der auf der Welle 11 einer jeden gegenstrichwalzenantriebsseitigen Aufnahme 5.1 angeordneten Riemenscheibe 13 und den auf den Antriebszapfen 6.11 der zu dieser Rauhwalzeneinheit 5 gehörenden Gegenstrichwalzen 6.1 angeordneten Riemenscheiben 9 ist die kraftschlüssige Leistungsübertragung durch den Riementrieb 16 gebildet (Fig. 3).
The scraper rollers 6 are driven as follows:
For driving the counter-scraper rollers 6.1 and that of the scraper rollers 6.2, there is a non-positive power transmission between the pulley 14 and the pulleys 12 through a belt drive 15 to the shafts 11 mounted in the receptacles 5.1. The non-positive power transmission through the belt drive 16 is formed between the pulley 13 arranged on the shaft 11 of each receptacle roller drive-side receptacle 5.1 and the belt pulleys 9 arranged on the drive journal 6.11 of the counter-stroke rollers 6.1 belonging to this roughing roller unit 5 (FIG. 3).

Für den Antrieb der Strichwalzen 6.2 (Fig. 4) ist zwischen der auf der Welle 11 einer jeden strichwalzenantriebsseitigen Aufnahme 5.1 angeordneten Riemenscheibe 13 und den auf den Antriebszapfen 6.21 der zu dieser Rauhwalzeneinheit 5 gehörenden Strichwalzen 6.2 angeordneten Riemenscheiben 9 die kraftschlüssige Leistungsübertragung durch den Riementrieb 16 gebildet. Um denselben Umschlingungswinkel auch auf der Antriebsseite der Strichwalze 6.2 zu besitzen, befindet sich in dieser Antriebsverbindung eine lose auf dem Zapfen 6.12 der Gegenstrichwalze 6.1 gelagerte Riemenscheibe 10.For driving the line rollers 6.2 (FIG. 4), the non-positive power transmission through the belt drive 16 is between the belt pulley 13 arranged on the shaft 11 of each holder 5.1 on the line roller drive and the belt pulleys 9 arranged on the drive journal 6.21 of the line rollers 6.2 belonging to this roughing roller unit 5 educated. At the same wrap angle on the drive side too owning the line roller 6.2, there is a pulley 10 loosely mounted on the journal 6.12 of the counter-line roller 6.1 in this drive connection.

Im Ausführungsbeispiel wurden als Antriebselemente die Riementriebe 15, 16 genannt. Hierbei können vozugweise Keil- und/oder Zahnriemen oder aber auch andere Übertragungselemente, auch in Kombination mit den vorstehend genannten Übertragungselementen, Anwendung finden. Auf die Darstellung der Spannelemente für die Riementriebe 15, 16 wurde ebenfalls aus Gründen der Übersichtlichkeit verzichtet.In the exemplary embodiment, the belt drives 15, 16 were mentioned as drive elements. V-belts and / or toothed belts or else other transmission elements can also be used here, also in combination with the transmission elements mentioned above. The tensioning elements for the belt drives 15, 16 have also not been shown for reasons of clarity.

Der Antrieb der Gegenstrichwalzen 6.1, der Strichwalzen 6.2, des Tambours und der Zugwalzen 17 kann sowohl durch einen gemeinsamen Motor, aber auch durch gesonderte regelbare Motoren erfolgen. Insbesondere sind die Antriebe der Gegenstrichwalzen 6.1 und der Strichwalzen 6.2 getrennt voneinander regel- beziehungsweise steuerbar.The counter-coating rollers 6.1, the coating rollers 6.2, the drum and the drawing rollers 17 can be driven both by a common motor but also by separate controllable motors. In particular, the drives of the counter-coating rollers 6.1 and the coating rollers 6.2 can be regulated or controlled separately from one another.

Ohne von der Erfindung abzuweichen, ist es ferner möglich, daß jede Rauhwalzeneinheit 5 anstelle von zwei Gegentrichwalzen 6.1 und einer Strichwalze 6.2 mit einer Gegenstrichwalze 6.1 und zwei Strichwalzen 6.2 bestückt ist. Ferner ist es auch möglich, die Rauhwalzeneinheit 5 so zu gestalten, daß die Rauhwalzeneinheit 5 mit einer anderen Anzahl von Gegenstrichwalzen 6.1 und Strichwalzen 6.2 zu bestückenWithout deviating from the invention, it is furthermore possible for each roughing roller unit 5 to be equipped with a counter-coating roller 6.1 and two coating rollers 6.2 instead of two counter-scraper rollers 6.1 and a scraper roller 6.2. Furthermore, it is also possible to design the nip roller unit 5 in such a way that the nip roller unit 5 can be equipped with a different number of counter-coating rollers 6.1 and line rollers 6.2

Eine weitere Möglichkeit wird darin gesehen, daß die unterschiedliche Walzenart auch darin bestehen kann, daß Gegenstrichwalzen 6.1 oder Strichwalzen 6.2 mit unterschiedlichem Kratzenbeschlag versehen sind.Another possibility is seen in the fact that the different Type of roller can also consist in that counter-coating rollers 6.1 or line rollers 6.2 are provided with different scraper fittings.
