Description

Die Erfindung betrifft eine Vorrichtung zum Behandeln einer endlosen Ware mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a device for treating an endless product with the features of the preamble of claim 1.

Aus der DE-OS 34 19 487 ist eine Vorrichtung der eingangs genannten Art bekannt, bei der eine Textilbahn oder dergleichen über eine Mehrzahl von oberen und unteren Umlenkwalzen geführt wird, wobei wenigstens eine der oberen Umlenkwalzen mit Antrieben versehen ist. Weiter ist eine Pendelwalze vorgesehen, die die gewünschte Warenspannung bewirkt. Die Antriebe werden dabei über ein Signal gesteuert, das der Differenz zwischen den Kräften, die von der Textilbahn auf zwei der Walzen ausgeübt wird, entspricht.From DE-OS 34 19 487 a device of the type mentioned is known, in which a textile web or the like is guided over a plurality of upper and lower deflecting rollers, at least one of the upper deflecting rollers being provided with drives. A pendulum roller is also provided, which brings about the desired fabric tension. The drives are controlled by a signal that corresponds to the difference between the forces exerted by the textile web on two of the rollers.

Aus der CH-A-458 004 ist es weiter bekannt, eine Regelgröße für das Antriebsmoment durch Messung der auf eine ausgangsseitig angeordnete, nicht angetriebene Walze zu gewinnen.From CH-A-458 004 it is also known to obtain a controlled variable for the drive torque by measuring the non-driven roller arranged on the output side.

Das Regelverhalten der eingangs genannten Vorrichtung ist ungenügend.The control behavior of the device mentioned at the beginning is insufficient.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Vorrichtung derart auszubilden, daß diese ein besseres Regelverhalten zeigt.The invention has for its object to design the device mentioned in such a way that it shows better control behavior.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung an.According to the invention, this object is achieved by the features specified in the characterizing part of claim 1. The subclaims indicate advantageous embodiments of the invention.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der Zeichnung, in der Ausführungsbeispiele der Erfindung schematisch dargestellt sind. Dabei zeigt:

Fig. 1
ein erstes Ausführungsbeispiel der Erfindung, und
Fig. 2
ein zweites Ausführungsbeispiel der Erfindung.
Further features and advantages of the invention result from the drawing, in which exemplary embodiments of the invention are shown schematically. It shows:
Fig. 1
a first embodiment of the invention, and
Fig. 2
a second embodiment of the invention.

Die Vorrichtung besteht aus einer Mehrzahl von in einem Gehäuse 54 aufgenommenen oberen Umlenkwalzen 10, 12, 14, die jeweils über Antriebe 16, 18, 20 angetrieben werden, und nicht angetriebenen unteren Umlenkwalzen 22, 24, 26, 28, 30 sowie einer zwischen den eingangsseitigen unteren Umlenkwalzen 22, 24 angeordneten Pendelwalze 32 (insoweit entspricht die Vorrichtung weitgehend der aus der DE-OS 34 19 487 vorbekannten Vorrichtung).The device consists of a plurality of upper deflection rollers 10, 12, 14 accommodated in a housing 54, each of which is driven by drives 16, 18, 20, and non-driven lower deflection rollers 22, 24, 26, 28, 30 and one between the lower deflection rollers 22, 24 arranged on the input side, pendulum roller 32 (to this extent the device largely corresponds to the device known from DE-OS 34 19 487).

Bei beiden Ausführungsbeispielen ist die letzte der unteren Umlenkwalzen 30 mit Kraftmeßlagern 34 versehen, dessen Ausgangssignal an einen Istwert-Signaleingang 40 einer Regeleinrichtung 36 zugeführt wird. Diese als Thyristor-Speisegerät ausgebildete Regeleinrichtung 36 wirkt auf die Antriebe 16, 18, 20 der oberen Umlenkwalzen 10, 12, 14 (obwohl bei den dargestellten Ausführungsbeispielen alle drei oberen Umlenkwalzen mit gesonderten Antrieben versehen ist, ist es auch ausreichend, wenn lediglich eine oder zwei der oberen Umlenkwalzen 10, 12, 14 angetrieben wird, bzw. angetrieben werden).In both exemplary embodiments, the last of the lower deflection rollers 30 is provided with force measuring bearings 34, the output signal of which is fed to an actual value signal input 40 of a control device 36. This control device 36, designed as a thyristor supply device, acts on the drives 16, 18, 20 of the upper deflecting rollers 10, 12, 14 (although in the exemplary embodiments shown, all three upper deflecting rollers are provided with separate drives, it is also sufficient if only one or two of the upper deflecting rollers 10, 12, 14 is driven or driven).

Bei dem in Fig. 1 dargestellten Ausführungsbeispiel ist ein manuell einstellbarer Druckminderer 42 vorgesehen, der die Pendelwalze 32 beaufschlagt. Über einen Druck/Strom-Wandler 44 wird der Druck, mit dem die Pendelwalze 32 beaufschlagt wird, in ein elektrisches Signal umgewandelt, das über einen Anpassungsverstärker 46 an einen Sollwert-Signaleingang 38 der Regeleinrichtung 36 angelegt wird.In the exemplary embodiment shown in FIG. 1, a manually adjustable pressure reducer 42 is provided which acts on the pendulum roller 32. Via a pressure / current converter 44, the pressure with which the pendulum roller 32 is acted upon is converted into an electrical signal, which is applied via an adaptation amplifier 46 to a setpoint signal input 38 of the control device 36.

Das Ausführungsbeispiel nach Fig. 2 unterscheidet sich von dem nach Fig. 1 insofern, als hier der an dem Sollwert-Signaleingang 38 anliegende, manuell zu wählende Wert über ein Potentiometer 48 bestimmt wird, wobei dieses elektrische Signal über einen Anpassungsverstärker 50 und einen Strom/Druck-Wandler 52 auf die Pendelwalze 32 aufgegeben wird.The exemplary embodiment according to FIG. 2 differs from that according to FIG. 1 in that the value to be selected manually at the setpoint signal input 38 is determined via a potentiometer 48, this electrical signal using an adaptation amplifier 50 and a current / Pressure converter 52 is abandoned on the pendulum roller 32.

Das gegenüber dem Stand der Technik verbesserte Regelverhalten der Vorrichtung beruht darauf, daß nicht zwei Ist-Werte miteinander verglichen werden, sondern die von der Regelstrecke abgegebene Regelgröße (nämlich die Kraft an der letzten der Umlenkwalzen 30) mit einem vorgegebenen Sollwert verglichen wird. Die manuell eingegebene Eingangsgröße wird zu diesem Zweck gleichzeitig auf die das Stellglied bildende Pendelwalze 32 sowie auf die Regelstrecke bestehend aus dem Thyristor-Speisegerät 36, dem Antrieb 16, 18, 20 und dem Kraftmittel 34 gegeben.The control behavior of the device, which is improved compared to the prior art, is based on the fact that two actual values are not compared with one another, but rather the control variable emitted by the controlled system (namely the force on the last of the deflection rollers 30) is compared with a predetermined target value. For this purpose, the manually entered input variable is simultaneously applied to the pendulum roller 32 forming the actuator and to the controlled system consisting of the thyristor supply device 36, the drive 16, 18, 20 and the power means 34.

Die Vorsehung eines Druck/Strom-Wandlers 44 bzw. eines Strom/Druck-Wandlers 52 sowie der Anpassungsverstärker 46 bzw. 50 beruht darauf, daß Pendelwalze 32 und das Thyristor-Speisegerät ihrer Eingangsgrößen unterschied licher Form, nämlich einerseits pneumatisch oder hydraulisch und andererseits elektrisch benötigen.The provision of a pressure / current converter 44 or a current / pressure converter 52 as well as the matching amplifier 46 or 50 is based on the fact that the pendulum roller 32 and the thyristor supply device differentiate their input variables Licher form, namely pneumatic or hydraulic on the one hand and electrical on the other hand.

Die in der vorstehenden Beschreibung, in der Zeichnung sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung ihren verschiedenen Ausführungsformen wesentlich sein.The features of the invention disclosed in the above description, in the drawing and in the claims can be essential both individually and in any combination for the implementation of the invention in its various embodiments.
