Abstract

The measurement roller, to monitor the pressure development in a press roller gap, has a roller mantle (1) of plastics with at least one encapsulated pressure sensor (2) to show the pressure applied to the web (3) passing through the roller gap during the rotation of the press roller. A transmitter (5) for the measured values is also within the roller mantle plastics, with an electrical connection (4) to the sensor. The plastics mantle is reinforced by filaments (8), to which the pressure sensor(s) and transmitter(s) are attached for additional strength. The press roller is only used as a measurement roller for a defined measurement time.

Description

Die Erfindung betrifft einen Walzenmantel für eine rotierbare Presswalze zumindest teilweise aus einem Kunststoff bestehend, dessen Herstellung sowie die Anwendung des Walzenmantels in Presswalzen zum Messen des Druckverlaufs in einem Pressspalt einer Maschine zur Herstellung und/oder Veredlung einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn.The invention relates at least to a roll shell for a rotatable press roll partially consisting of a plastic, its production and use of the roll shell in press rolls for measuring the pressure curve in one Press nip of a machine for producing and / or finishing a paper, cardboard, Tissue or other fibrous web.

Die einzige Möglichkeit, den Druckverlauf im Pressspalt von durchbiegungsgesteuerten Presswalzen quantitativ zu erfassen, ist die Auswertung des hydrodynamischen Schmierfilms zwischen Walzenmantel und Stützeinrichtung, d.h. im allgemeinen dem Stützschuh. Dies erfordert jedoch eine feste Installation in der Presswalze und Bohrungen im Stützschuh.
Dies ist relativ aufwendig.
The only way to quantitatively record the pressure profile in the press nip of deflection-controlled press rolls is to evaluate the hydrodynamic lubricating film between the roll jacket and the support device, ie generally the support shoe. However, this requires a fixed installation in the press roll and holes in the support shoe.
This is relatively expensive.

Die Aufgabe der Erfindung ist es daher, die Messung des Druckverlaufs im Pressspalt mit einfachen Mitteln zu ermöglichen.The object of the invention is therefore to measure the pressure profile in the press nip with simple means.

Erfindungsgemäß wurde die Aufgabe hinsichtlich des Walzenmantels dadurch gelöst, dass sich im Kunststoff zumindest ein Drucksensor befindet. Dieser Drucksensor erfasst den, auf den Walzenmantel beim Lauf durch den Pressspalt auf den Kunststoff ausgeübten Druck. Dieser Druck ist ein Maß für den, auf die, durch den Pressspalt geführte Materialbahn ausgeübten Druck und kann so zur Auswertung bei Problemen verwendet werden. Diese Messvorrichtung ist einfach aufgebaut und mit einer hohen Genauigkeit verbunden.According to the invention, the object with respect to the roll shell was achieved by that there is at least one pressure sensor in the plastic. This pressure sensor detects the, on the roll shell when running through the press nip on the Plastic pressure. This pressure is a measure of who, by whom Press nip guided material web exerted pressure and can thus contribute to the evaluation Problems are used. This measuring device is simply constructed and with associated with high accuracy.

Um den Druckverlauf axial entlang des Pressspaltes erfassen zu können, sollten sich im Kunststoff mehrere, vorzugsweise zumindest axial über den Walzenmantel verteilt angeordnete Drucksensoren befinden. Die Drucksensoren können außerdem auch radial über den Walzenmantel verteilt sein, was den Messbereich erweitert. In order to be able to record the pressure curve axially along the press nip, should in the plastic several, preferably at least axially distributed over the roll shell arranged pressure sensors are located. The pressure sensors can also be distributed radially over the roll shell, which extends the measuring range.

Im Interesse einer zeitnahen Auswertung und einer einfach und funktionssicher aufgebauten Messvorrichtung sollte dem Drucksensor ein Messwert-Sender zugeordnet werden, welcher vorzugsweise im oder am Walzenmantel angeordnet ist.
Dabei kann jeder Drucksensor seinen eigenen oder mehrere Drucksensoren einen Messwert-Sender besitzen.
In the interest of timely evaluation and a simple and functionally reliable measuring device, a pressure transmitter should be assigned to the pressure sensor, which is preferably arranged in or on the roller shell.
Each pressure sensor can have its own pressure sensor or several pressure sensors.

Der Einbau der Messvorrichtung ist bei unterschiedlichen Arten von Walzenmänteln möglich. Dabei sollte jedoch der Walzenmantel zumindest überwiegend, vorzugsweise gänzlich aus Kunststoff und/oder zumindest ein äußere Schicht, vorzugsweise die Außenschicht des Walzenmantel aus Kunststoff bestehen.The installation of the measuring device is with different types of roller shells possible. However, the roller jacket should at least predominantly preferably entirely made of plastic and / or at least one outer layer, preferably the outer layer of the roll shell made of plastic.

Insbesondere wenn der Walzenmantel überwiegend oder gänzlich aus Kunststoff besteht, so besitzt dieser oft Verstärkungselemente, vorzugsweise in Form von Verstärkungsfäden. Diese Verstärkungselemente erhöhen die mechanische Belastbarkeit und die Formbeständigkeit des Walzenmantels. Hinsichtlich der sicheren Positionierung des Drucksensors ist es dabei vorteilhaft, wenn der Drucksensor mit zumindest einem Verstärkungselement mechanisch verbunden ist.Especially if the roller shell is predominantly or entirely made of plastic there is, this often has reinforcing elements, preferably in the form of Reinforcing threads. These reinforcing elements increase the mechanical Resilience and dimensional stability of the roll shell. With regard to the safe positioning of the pressure sensor, it is advantageous if the Pressure sensor is mechanically connected to at least one reinforcing element.

Um den Pressdruck im Pressspalt während der Druck-Messung erzeugen zu können, sollte zwischen der Achse der Presswalze und dem Walzenmantel eine Stützeinrichtung angeordnet sein.In order to be able to generate the press pressure in the press nip during the pressure measurement, should be a between the axis of the press roll and the roll shell Support device may be arranged.

Das erfindungsgemäße Verfahren zur Herstellung des Walzenmantels ist dadurch gekennzeichnet, dass der Drucksensor in den Walzenmantel oder die Schicht aus Kunststoff eingegossen wird. Dies ist relativ einfach und erlaubt außerdem, dass während der Herstellung des Walzenmantels mit dem Drucksensor auch der Messwert-Sender und/oder eine elektrische Verbindung zum Messwert-Sender eingegossen wird.The process according to the invention for producing the roll shell is thereby characterized in that the pressure sensor in the roll shell or layer Plastic is poured. This is relatively simple and also allows that during the manufacture of the roll shell with the pressure sensor Measured value transmitter and / or an electrical connection to the measured value transmitter is poured.

Für die Anwendung des Walzenmantels in Presswalzen zum Messen des Druckverlaufs in einem Pressspalt ist wesentlich, dass die Presswalze nur über eine begrenzte Mess-Zeit als Messwalze in der Maschine eingesetzt wird. Dadurch wird der Einsatz je nach Bedarf in mehreren Maschinen möglich, was den Aufwand noch weiter verringert.For the application of the roll jacket in press rolls for measuring the Pressure course in a press nip is essential that the press roll only over one limited measuring time is used as a measuring roller in the machine. This will Depending on requirements, the use in several machines is possible, which adds to the effort further decreased.

Dabei sollte ein die Signale des Messwert-Senders empfangender Messwert-Empfänger außerhalb des Walzenmantels oder sogar der Presswalze angeordnet sein.A receiver should receive the signals from the transmitter arranged outside the roll shell or even the press roll his.

Nachfolgend soll die Erfindung an mehreren Ausführungsbeispielen näher erläutert werden. In der beigefügten Zeichnung zeigt:

  • Figur 1: einen schematischen Teil-Querschnitt durch einen Pressspalt,
  • Figur 2. einen schematischen Teil-Längsschnitt durch den Pressspalt und
  • Figur 3: einen schematischen Querschnitt durch eine andere Pressanordnung.
  • The invention will be explained in more detail below using several exemplary embodiments. The attached drawing shows:
  • FIG. 1: a schematic partial cross section through a press nip,
  • Figure 2. shows a schematic partial longitudinal section through the press nip and
  • Figure 3: a schematic cross section through another press arrangement.
  • In den Figuren 1 und 2 wird die Faserstoffbahn 3 eventuell auch gemeinsam mit zumindest einem endlos umlaufenden Band, beispielsweise in Form eines Pressfilzes durch einen von der Presswalze und einer Gegenwalze 6 gebildeten Pressspalt geführt. Während die Gegenwalze 6 eine zylindrische Form besitzt, hat die zu Messzwecken eingebaute Presswalze einen flexiblen Walzenmantel 1. Dabei wird der Walzenmantel 1 über eine zwischen dem Walzenmantel 1 und der Achse der Presswalze angeordnete Stützeinrichtung 7 zur Gegenwalze 6 gedrückt. Die Stützeinrichtung 7 wird von einem hydraulisch angepressten Stützschuh gebildet, welcher zur Bildung eines verlängerten Pressspaltes mit der Gegenwalze 6 eine konkave Anpressfläche besitzt. Da hierdurch der Walzenmantel 1 während der Rotation einer enormen Belastung durch die Verformung im Bereich des Pressspaltes ausgesetzt ist, wird der Walzenmantel 1 von Verstärkungselementen 8 in Form von axial und radial verlaufenden Verstärkungsfäden verstärkt.In FIGS. 1 and 2, the fibrous web 3 may also be used together at least one endless belt, for example in the form of a press felt by a press nip formed by the press roll and a counter roll 6 guided. While the counter roller 6 has a cylindrical shape, it has Press roll built in for measuring purposes, a flexible roll jacket 1 Roller shell 1 over a between the roller shell 1 and the axis of Pressing device 7 pressed to the counter roller 6 pressed. The Support device 7 is formed by a hydraulically pressed support shoe, which to form an extended press nip with the counter roller 6 a has a concave contact surface. As a result, the roller shell 1 during Rotation of an enormous load due to the deformation in the area of the press nip is exposed, the roll shell 1 of reinforcing elements 8 in the form of reinforced axially and radially extending reinforcing threads.

    Um dabei den Druckverlauf im Pressspalt messen zu können, sind in den Walzenmantel 1 mehrere axial nebeneinander angeordnete Drucksensoren 2 eingegossen. Diese Drucksensoren 2 sind über eine ebenfalls in den Walzenmantel 1 eingegossene elektrische Verbindung 4 mit einem Messwert-Sender 5 verbunden, welcher die Messwert-Signale an einen außerhalb der Presswalze angeordneten Messwert-Empfänger übermittelt. Dieser Messwert-Empfänger ist mit einer Datenverarbeitungseinheit zur Auswertung der Messergebnisse verbunden.In order to be able to measure the pressure curve in the press nip, in the Roller jacket 1 a plurality of pressure sensors 2 arranged axially next to one another cast. These pressure sensors 2 are also in the roll shell 1 cast electrical connection 4 connected to a measured value transmitter 5, which arranged the measured value signals to an outside of the press roller Measured value receiver transmitted. This measurement receiver is with a Data processing unit connected for evaluating the measurement results.

    In beiden Fällen sind die Drucksensoren 2 mit den Verstärkungsfäden des Walzenmantels 1 mechanisch verbunden, so dass während des Eingießens bereits eine Fixierung gewährleistet ist. Während in dem in Figur 1 gezeigten Beispiel der Messwert-Sender 5 gemeinsam mit den Drucksensoren 2 in den Walzenmantel 1 eingegossen wurde und jedem Drucksensor 2 ein Messwert-Sender 5 zugeordnet ist, ist der Messwert-Sender 5 in Figur 2 außerhalb des Walzenmantels 1 an dessen Innenfläche befestigt. Gemäß Figur 2 sind mehrere oder sogar alle Drucksensoren 2 mit nur einem Messwert-Sender 5 verbunden, wobei sich der Messwert-Sender 5 außerhalb der Stützeinrichtung 7 am Ende des Walzenmantels 1 befindet und die elektrische Verbindung 4 entlang der Verstärkungsfäden verläuft.In both cases, the pressure sensors 2 with the reinforcing threads of the Roll shell 1 mechanically connected so that already during the pouring fixation is guaranteed. While in the example shown in Figure 1 Measured value transmitter 5 together with the pressure sensors 2 in the roll shell 1 was poured in and each pressure sensor 2 is assigned a measured value transmitter 5, is the measured value transmitter 5 in Figure 2 outside the roll shell 1 on the other Fixed inside surface. According to FIG. 2, several or even all pressure sensors 2 connected to only one measured value transmitter 5, the measured value transmitter 5 is located outside the support device 7 at the end of the roll shell 1 and the electrical connection 4 runs along the reinforcing threads.

    Figur 3 zeigt im Gegensatz hierzu einen Pressspalt, durch den während der Messung des Druckverlaufs im Pressspalt weder eine Faserstoffbahn 3 noch ein Band geführt wird. Außerdem haben die Gegenwalze 6 und die Presswalze eine zylindrische Form, wobei die Presskräfte über die Achsen der Presswalze und der Gegenwalze 6 eingeleitet werden. Die Presswalze besitzt hierzu einen Walzenmantel 1 aus Kunststoff, welcher sich auf einer Stützeinrichtung 7 in Form der Walzenachse abstützt. Da hier keine Verformung des Walzenmantels 1 wie in den obigen Beispielen erfolgt, sind auch keine Verstärkungselemente im Kunststoff erforderlich. In den Kunststoff sind axial und radial verteilt mehrere kompakte Messeinheiten jeweils in Form eines Drucksensors 2, der elektrischen Verbindung 4 und dem Messwert-Sender 5 eingegossen.In contrast, Figure 3 shows a press nip through which during the measurement of the pressure curve in the press nip neither a fibrous web 3 nor a band becomes. In addition, the counter roll 6 and the press roll have a cylindrical shape, wherein the press forces over the axes of the press roll and the counter roll 6 be initiated. For this purpose, the press roll has a roll jacket 1 Plastic, which is on a support device 7 in the form of the roller axis supported. Since there is no deformation of the roll shell 1 as in the above Examples are done, no reinforcing elements in the plastic are required. Several compact measuring units are distributed axially and radially in the plastic each in the form of a pressure sensor 2, the electrical connection 4 and the Measured value transmitter 5 cast in.
