Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Beschlichten einer Fadenschar mit mindestens einem Schlichteabteil zum Kontaktieren des Garns der Schar mit Schlichteflotte und mindestens einem Schlichtequetschwerk, das aus gegeneinander gepreßten Walzen besteht.The invention relates to a method and an apparatus for coating a Thread sheet with at least one size compartment for contacting the yarn of the sheet with sizing liquor and at least one sizing squeezer that separates from each other pressed rollers.
Es sind Quetschwerke sehr verschiedener Art und Aufgabe sowie für die Behandlung diverser Substrate bekannt, z.B. für Bänder, Bahnen oder Fadenscharen, Textilien oder Papier sowie als Kalander.They are squeezers of very different types and tasks as well as for treatment known of various substrates, e.g. for tapes, webs or thread sheets, textiles or Paper as well as a calender.
Aus der GB-A 830 836 ist ein Verfahren und eine Vorrichtung zur automatischen Regelung eines kontinuierlichen Auftrags einer bestimmten Menge Feststoff oder Flüssigkeit auf eine bewegte Warenbahn, z.B. Papier, beschrieben. Zur Regelung des Stoffauftrages wird der Achsabstand zwischen zwei Walzen eines Quetschwerks durch ein mechanisches Hubgetriebe variiert.GB-A 830 836 describes a method and a device for automatic control a continuous application of a certain amount of solid or liquid on a moving web, e.g. Paper, described. To regulate the material order, the The center distance between two rollers of a crushing unit is varied by a mechanical lifting gear.
In Schlichtvorrichtungen ist es üblich, die zu behandelnde Fadenschar mit Schlichteflotte zu beaufschlagen, insbesondere in einem Trog zu tauchen und dann in einem Quetschwerk überschüssige Schlichte abzutrennen. Eine solche Vorrichtung wird in DE 32 03 087 A1 beschrieben. Im Bekannten werden Mittel zum Einstellen des Anpreßdrucks der beiden Walzen in deren Quetschfuge vorgesehen. Der Anpreßdruck der Walzen kann in Abhängigkeit von der Schlichtemenge geregelt werden, die nach dem Quetschen auf der Fadenschar verbleibt.In sizing devices, it is customary to treat the thread sheet to be treated with a sizing liquor to act, especially to dive in a trough and then in a Squeeze out excess sizing. Such a device is in DE 32 03 087 A1 described. Known are means for adjusting the contact pressure of the two rollers provided in their pinch joint. The contact pressure the rollers can be regulated depending on the amount of size that after squeezing remains on the thread sheet.
Es gibt Meßgeräte, sogenannte Auftragsmeßgeräte, die es erlauben, die Menge der auf einer Fadenschar nach dem Quetschen verbleibenden Schlichte zu messen. Mit den Meßwerten können Quetschdruck-Regler gesteuert werden. Derartige Meßsysteme werden in DE 42 34 279 A1 angegeben. There are measuring devices, so-called order measuring devices, which allow the amount of measure the size remaining on a thread sheet after squeezing. With The squeeze pressure controller can be controlled from the measured values. Such measuring systems are specified in DE 42 34 279 A1.
Das Maß der Beschlichtung einer Fadenschar kann unter anderem abhängig sein von deren Vorbehandlung, etwa von der ursprunglichen Feuchte, es kann auch abhängig sein von der Geschwindigkeit, mit der die Schlichte aufgetragen und abgequetscht wird, es kann weiterhin abhängig sein, von der Konzentration der aufgetragenen Schlichte. Wenn eine bestimmte Schlichtemenge erwünscht ist, werden die genannten Auftragsmeßgeräte, unter Umstanden an mehreren Stellen, z B. vor dem Schlichten und nach dem Abquetschen, vorgesehen. Die Meßergebnisse werden mit dem Ziel benutzt, den Quetschdruck, das heißt die spezifische Flächenpressung des Quetschwerks, so zu regeln, daß die vorgegebene Schlichtemenge auf der Fadenschar verbleibt.The degree of sizing of a thread group can be dependent, among other things it can also depend on their pretreatment, for example on the original moisture be of the speed with which the size is applied and squeezed off it may continue to depend on the concentration of the applied Plain. If a certain amount of size is desired, the Order measuring devices mentioned, under certain circumstances in several places, e.g. before Finishing and after squeezing. The measurement results are used with the aim of the squeezing pressure, that is the specific surface pressure of the squeeze mechanism to be regulated so that the specified amount of size on the thread sheet remains.
Herkommliche Vorrichtungen zum Einstellen und Regeln des Quetschdrucks arbeiten mit hydraulischen oder pneumatischen Zylindern. In der Regel wird die eine Walze des Quetschwerks fest eingespannt, wahrend man die andere Walze mit Hilfe hydraulischer oder pneumatischer Zylinder gegen die erste Walze preßt. Die Einstellung des Quetschdrucks und das Nachregeln des Drucks erfolgt also durch direkte Vorgabe von Druckwerten. Die entsprechenden Zylinder lassen sich auf einfache Weise, beispielsweise durch kurzzeitiges Öffnen oder Schließen eines Druckmittelventils, steuern. Bei sehr kompakten Anlagen, wie sie z.B. in DE 198 32 163 5 (98501) beschrieben werden, wird aber ein wesentlicher Nachteil pneumatischer oder hydraulischer Steuerungen gravierend. Diesen Systemen immanent ist namlich eine stets mehr oder weniger große Hysterese; das heißt der Quetschdruck des Walzenpaars in der Quetschfuge ändert sich auf unterschiedlichen Kennlinien, je nachdem ob er steigt oder fallt.Conventional devices for setting and regulating the squeeze pressure work with hydraulic or pneumatic cylinders. As a rule, one The roller of the crushing machine is firmly clamped, while the other roller is attached Hydraulic or pneumatic cylinders press against the first roller. The Setting the squeezing pressure and readjusting the pressure is therefore carried out by direct specification of pressure values. The corresponding cylinders can be opened simple way, for example by briefly opening or closing one Pressure fluid valve, control. In very compact systems, such as in DE 198 32 163 5 (98501), but becomes a major pneumatic disadvantage or hydraulic controls serious. Is immanent to these systems namely a more or less large hysteresis; that is the squeeze pressure of the roller pair in the pinch joint changes on different characteristic curves, depending on whether it rises or falls.
Ursache für die vorgenannten Hysterese-Erscheinungen sind Reibungswiderstände zwischen Kolben und Zylinder der bekannten pneumatischen oder hydraulischen Einrichtungen. Es gibt in der Praxis auch reibungsfrei arbeitende Systeme dieser Art mit sogenannten Balgzylindern. Diese Vorrichtungen arbeiten mit relativ großen Fluid-Volumen (Luft oder Flüssigkeit), die bei einer Druckverstellung in den Balg eingelassen oder aus dem Balg herausgedrückt werden müssen. Probleme bereiten die Balgzylinder-Systeme vor allem im Fall einer schnellen Geschwindigkeitsänderung, insbesondere bei einem Not-Stopp, der jeweiligen Maschine. In der Regel soll dann der vom Quetschwerk ausgeübte Druck fast augenblicklich bzw. in wenigen Sekunden auf ein von Qualität oder Viskosität des jeweiligen Schlichtemittels abhängiges Maß herabgesetzt werden. Eine solche plötzliche Druckänderung läßt sich mit herkömmlichen Balgzylinder-Systemen nicht erreichen, weil die Durchlaßquerschnitte der auf eine Regelbarkeit des Balgzylinderdrucks ausgelegten Ventile eine augenblickliche Druckbelastung nicht zulassen. Die durch den Einsatz der Balgzylinder erreichte Verminderung der Hysterese wird also durch eine beschränkte Reaktionsgeschwindigkeit und damit eine verspätete Druckentlastung bei Not-Stopps erkauft.The cause of the aforementioned hysteresis phenomena are frictional resistances between piston and cylinder of the known pneumatic or hydraulic Institutions. In practice, there are also systems of this type that work smoothly with so-called bellows cylinders. These devices work with relatively large ones Volume of fluid (air or liquid) that is in the bellows during a pressure adjustment must be let in or pushed out of the bellows. Cause problems the bellows cylinder systems, especially in the event of a rapid change in speed, especially in the event of an emergency stop of the respective machine. As a rule, should then the pressure exerted by the squeeze mechanism almost instantaneously or in a few Seconds depending on the quality or viscosity of the respective sizing agent Dimension can be reduced. Such a sudden change in pressure can be not reach with conventional bellows cylinder systems, because the passage cross sections of the valves designed for controllability of the bellows cylinder pressure Do not allow instantaneous pressure loading. The through the use of the bellows cylinder The reduction in hysteresis is achieved by a limited reaction speed and thus a delayed pressure relief during emergency stops he buys.
Der Erfindung liegt die Aufgabe zugrunde, die Genauigkeit der Einstellung des Quetschdrucks zu verbessern und die Regelung im wesentlichen hysterefrei zu machen, ohne die Reaktionsgeschwindigkeit zu beschränken.The invention has for its object the accuracy of the setting of To improve the squeezing pressure and to make the control essentially hysterical, without limiting the speed of reaction.
Die erfindungsgemäße Lösung besteht für das eingangs genannte Verfahren darin, daß der Anpreßdruck der Walzen unmittelbar durch Einstellen von deren Achsabstand gesteuert wird. Einige Verbesserungen und weitere Ausgestaltungen der Erfindung werden in den Unteransprüchen beschrieben.The solution according to the invention for the above-mentioned method consists in that the contact pressure of the rollers directly by adjusting their center distance is controlled. Some improvements and further refinements of the invention are described in the subclaims.
Der Erfindung liegt die Erkenntnis zugrunde, daß sich der Achsabstand der Quetschwalzen proportional zum Flächendruck und damit zum Abquetscheffekt ändert. Diese Proportionalität gilt insbesondere in den beim Abquetschen befeuchteter bzw. beschlichteter Fadenscharen üblichen Druckbereichen. Statt einer Zylinderdruckvorgabe (hydraulisch oder pneumatisch) wird erfindungsgemäß der gegenseitige Abstand der Walzenachsen - also unmittelbar ein Weg - eingestellt. Überraschenderweise liefert die unmittelbare und damit beliebig schnelle Wegeinstellung einen reproduzierbaren und hysteresefreien Meßwert proportional zum Flachendruck des Quetschwerks und damit zum Abquetscheffekt.The invention is based on the finding that the center distance of the Squeeze rollers change proportionally to the surface pressure and thus to the squeezing effect. This proportionality applies particularly to those moistened when squeezed or sized thread groups usual pressure ranges. Instead of a cylinder pressure specification (hydraulic or pneumatic) according to the invention is the mutual Distance between the roller axes - that is, a path directly. Surprisingly provides the immediate and therefore arbitrarily quick path setting a reproducible and hysteresis-free measured value proportional to the surface pressure of the crushing mechanism and thus to the squeezing effect.
Der Quetschdruck wird also erfindungsgemäß durch direkte Vorgabe von Wegwerten, nämlich des Achsabstands, geregelt. Der jeweilige Weg laßt sich mit Hilfe mechanischer, also verzogerungsfrei wirkender Mittel, z.B. durch ein mechanisches Hubgetriebe bzw. ein Spindelgetriebe aber auch durch hydraulische oder pneumatische Hubelemente, bei steigendem und fallendem Druck gleich bzw. exakt reproduzierbar einstellen, so daß die der Erfindung zugrundeliegende Aufgabe in nahezu idealer Weise gelöst wird. Wenn im vorliegenden Zusammenhang von der Hysteresefreiheit der Quetschdruckeinstellung gesprochen wird, heißt das, daß die Quetschdruckvorgabe im Rahmen der angestrebten Genauigkeit hysteresefrei ist.According to the invention, the squeezing pressure is determined by directly specifying path values, namely the center distance, regulated. The respective path can be i.e. agents without delay, e.g. through a mechanical Hoist gear or a spindle gear but also by hydraulic or pneumatic Lifting elements, with increasing and falling pressure the same or exactly reproducible adjust so that the object underlying the invention in almost ideally is solved. If in the present context of freedom from hysteresis the squeeze pressure setting is spoken, it means that the Squeeze pressure specification within the desired accuracy is hysteresis-free.
Es wird ein Verfahren zum Steuern des Anpreßdrucks der um ihre Achsen rotierbaren Walzen eines Quetschwerks beschrieben. Um eine hysteresefreie und im Fall eines Not-Stopps praktisch augenblickliche Änderung des Anpreßdrucks zu erreichen, wird dieser unmittelbar durch Einstellen des Achsabstands der Walzen gesteuert. Ein wesentlicher Vorteil der Erfindung bei normalen Druckregelungen ist die Hysteresefreiheit. Hierzu kommt vor allem der Vorteil der einen Druckbefehl mechanisch und damit unmittelbar folgenden QuetschdruckanderungIt becomes a method for controlling the contact pressure of the rotatable axes Rolling a crushing machine described. To a hysteresis-free and in the case to achieve an almost instantaneous change in the contact pressure of an emergency stop, this is controlled directly by adjusting the center distance of the rollers. A major advantage of the invention in normal pressure controls is that From hysteresis. In addition, there is the advantage of a mechanical pressure command and thus the immediately following change in pinch pressure
