Eine solche Vorrichtung ist bereits aus der EP-A-0467117 bekannt. Dabei ist der Dickenfühler durch eine Mehrzahl von nebeneinander angeordneten und durch den Wickel einzeln verstellbaren Einzelfühlem gebildet, die sich über die Breite des Wickels erstrecken. In jedem Einzelfühler ist eine elektrische Messvorrichtung für die Erfassung der Stellung des Einzelfühlers zur Führung angeordnet. Damit stehen Signale für die Stellung jedes Einzelfühlers zur Verfügung, die es erlauben, Unterschiede in der Dicke des Wickels, die über die Breite des Wickels gesehen bestehen, zu erkennen.Such a device is already known from EP-A-0467117. Here is the thickness sensor by a plurality of side by side and individually adjustable by the winding Single sensor formed, which extend across the width of the winding. In each Single sensor is an electrical measuring device for detecting the position of the Single sensor arranged for guidance. So there are signals for the position of everyone Single sensors are available that allow differences in the thickness of the wrap that over seen the width of the wrap.
Ein Nachteil dieser bekannten Vorrichtung besteht darin, dass die Anordnung einer elektrischen Messvorrichtung in jedem Einzelfühler aufwendig und teuer ist. Arbeitet die Messvorrichtung mit Dehnmessstreifen, so muss jede einzelne Messvorrichtung vor der Inbetriebnahme sorgfältig geeicht werden, was ein aufwendiges Verfahren ist.A disadvantage of this known device is that the arrangement of a electrical measuring device in each individual sensor is complex and expensive. Does that work Measuring device with strain gauges, each individual measuring device must be in front of the Commissioning must be carefully calibrated, which is a complex process.
Es ist deshalb eine Aufgabe der vorliegenden Erfindung, wie sie in den Patentansprüchen gekennzeichnet ist, eine solche Vorrichtung zu schaffen, die einfacher und billiger ist, ohne dass Einbussen bei der Qualität der Messungen hingenommen werden müssen. It is therefore an object of the present invention as characterized in the claims is to create such a device that is simpler and cheaper without Losses in the quality of the measurements have to be accepted.
Dies wird dadurch erreicht, dass ein Übertragungselement, das zur Übertragung der Bewegung des Dickenfühlers an das Wegmesssystem in einer wählbaren, zur Bewegungsrichtung des Dickenfühlers beliebig geneigten Richtung ausgebildet und angeordnet ist. Dadurch kann ein Wegmesssystem in einer beliebig wählbaren Richtung arbeitend vorgesehen sein.This is achieved by having a transmission element that is used to transmit the movement of the thickness sensor to the position measuring system in a selectable direction of movement the thickness sensor is formed and arranged in any inclined direction. This can a position measuring system can be provided working in any direction.
Neben dem einfacheren Aufbau einer solchen Vorrichtung ergibt sich gemäss den Merkmalen des Anspruchs 5 der weitere Vorteil, dass gleichzeitig die Auslenkungen aller Einzelfühler addiert werden, so dass ein Signal entsteht, das die mittlere Dicke des Wickels darstellt. Somit muss dieses Signal nicht mehr durch elektrische Verarbeitung von Einzelsignalen ermittelt werden. Die Vorrichtung kann auf einfache Weise für einen, zwei oder mehrere Einzelfühler ausgelegt oder auch nachträglich auf mehrere Einzelfühler erweitert werden. Beim Einsatz der erfindungsgemässen Vorrichtung in einer Karde mit offenem Regelkreis, kann diesem direkt ein über die Breite gemittelter Wert für die Dicke des Wickels zugeführt werden, was eine genauere Regelung ermöglicht und zu einer verbesserten Gleichmässigkeit des Bandes am Auslauf der Karde führt.In addition to the simpler construction of such a device, the features also show of claim 5, the further advantage that the deflections of all individual sensors are added at the same time so that a signal is generated that represents the average thickness of the roll. Consequently this signal no longer has to be determined by electrical processing of individual signals become. The device can easily be used for one, two or more individual sensors designed or expanded to several individual sensors. When using the The device according to the invention in a card with an open control circuit can do this directly a width-averaged value for the thickness of the wrap can be supplied, which is a more accurate Regulation enables and to improve the uniformity of the belt on Carding spout leads.
Nachstehend wird die Erfindung anhand von Ausführungsbeispielen und Zeichnungen näher
erläutert. Es zeigen:
Fig. 1 zeigt eine erfindungsgemässe Vorrichtung. Dabei erkennt man einen Wickel 1, der auf
einer festen Führung 2 aufliegt und der vorzugsweise als loses Fasergebilde wie z.B. Watte oder
ein Vlies erscheint, das nachfolgend als Wickel bezeichnet wird. Ein Dickenfühler 3 ist auf dem
Wickel 1 aufliegend oder sogar eintauchend vorgesehen, der hier insbesondere als hohle Messwalze
3' ausgebildet ist. Die Innenfläche 4 der Messwalze 3' weist zwei ringförmige Nuten 5, 6
auf, die zur seitlichen Führung von Rollenpaaren 7, 8 dienen, die sich auf der Messwalze 3'
abstützen. Die Rollenpaare 7, 8 weisen Drehachsen 9, 10 auf, die in einem Wagen 11 gelagert
sind. Dieser weist eine Stütze 12 auf, die zur Lagerung einer Umlenkrolle 13 für ein Übertragungselement
14 dient, das biegsam aber möglichst unelastisch sein soll und hier beispielsweise
als Seil ausgebildet ist. Zwei weitere Umlenkrollen 15, 16 sind in einem Balken 17 gelagert, der
über Stimflächen 18, 19 der Messwalze 3' hinausragt und in dem das eine Ende 20 des Übertragungselementes
14 fest gelagert ist. Das andere Ende 21 des Übertragungselementes 14 ist
an ein Wegmesssystem 22 angeschlossen und bewegt sich in Richtung eines Pfeiles 23, wenn
die Messwalze 3' zur Führung 2 hin oder davon wegbewegt wird. Der Pfeil 23 zeigt damit eine
Richtung an, die zu einer Bewegungsrichtung des Dickenfühlers 3, wie sie durch einen Pfeil 24
angegeben ist, geneigt oder abgewinkelt ist. Das Wegmesssystem 22 besteht neben dem eigentlichen
Wegmesselement 22a auch aus einer Feder 22b, einer einstellbaren Lagerung 22c für
die Feder 22b am Balken 17 und einem Kupplungselement 22d für das Übertragungselement 14,
das hier auch als Messfläche für das eigentliche Wegmesselement 22a dient. Man erkennt hier
auch, dass eine Bewegung der Messwalze 3' in der Richtung des Pfeiles 24 wegen der Bildung
einer Schleife im Übertragungselement 14 eine doppelt so grosse Auslenkung des Endes 21 im
Bereiche des Wegmessystemes 22 ergibt. Damit kann auch eine Verdoppelung der Messgenauigkeit
erreicht werden. Die Anpresskraft des Dickenfühlers 3 gegen die Führung 2 wird (neben
der Schwerkraft) von der Feder 22b erzeugt.1 shows a device according to the invention. You can see a wrap 1 on
a
Fig. 2 zeigt einen Querschnitt durch die in Fig. 1 gezeigte Vorrichtung. Dann erkennt man wiederum
die Rollenpaare 7, 8, den Wagen 11 mit der Stütze 12 und der Umlenkrolle 13, sowie den
Balken 17 mit den Umlenkrollen 15, 16 und einer Achse 25 zu deren Lagerung im Balken 17. Wie
aus den Fig. 1 und 2 hervorgeht, bildet die Führung 2 hier im wesentlichen eine Ebene. FIG. 2 shows a cross section through the device shown in FIG. 1. Then you recognize again
the pairs of rollers 7, 8, the
Fig. 3 zeigt eine Vorrichtung mit drei Dickenfühlem 26, 27, 28, die hier alle auf einem gemeinsamen
Balken 29 über einer Führung 30 gelagert sind. Der Aufbau der Dickenfühler 26, 27, 28 ist
derjenige, der bereits aus den Fig. 1 und 2 bekannt ist. Dabei haben aber alle Dickenfühler 26,
27, 28 ein gemeinsames Übertragungselement 31 und ein gemeinsames Wegmesssystem 32,
das auf einer Seite der drei Dickenfühler 26, 27. 28 auf dem Balken 29 befestigt ist. Der Balken
29 kann beispielsweise in hier nicht näher dargestellter, aber bekannter Art und Weise mit der
Führung 30 verbunden sein, sich darauf abstützen oder in irgend einer anderen Weise, insbesondere
ortsfest und in einem festen Abstand zur Führung gelagert sein. Das Übertragungselement
31 durchquert hier mehrere Messwalzen, die zwischen dem Wegmesssystem 32 und
einer festen Lagerung 51 angeordnet sind. Im Wegmesssystem 32 ist auch eine feste Lagerung
32c für eine Feder 32b vorgesehen die über ein Kupplungselement 32d mit dem Übertragungselement
31 verbunden ist. Die Lagerung 32c ist längs des Balkens 29 verschieb- und einstellbar,
so dass die Spannkraft der Feder 32b und damit auch die Andruckkraft aller vorgesehenen Dikkenfühler
26, 27, 28 gemeinsam einstellbar ist.Fig. 3 shows a device with three
Fig. 4 zeigt nochmals den Einsatz eines erfindungsgemässen Dickenfühlers 3 über einer stationären
und ebenen Führung 2 mit einem Wickel 1, der durch hier nicht gezeigte Mittel in Richtung
eines Pfeiles 33 angetrieben ist und damit die Messwalze 3' antreibt. Im Bereiche des Dickenfühlers
3 erfährt der Wickel 1 eine Verdichtung, so dass sich seine Höhe auf einen Betrag a vemngert.FIG. 4 again shows the use of a
Fig. 5 zeigt einen Dickenfühler 3 wie er über einer runden Führung, hier einer Walze 34, die in
Richtung eines Pfeiles 35 angetrieben ist, angeordnet sein kann. Auch hier ergibt sich eine Verdichtung
des Wickels 1 auf den Betrag a.Fig. 5 shows a
Fig. 6 zeigt einen Dickenfühler 3 wie er über einer mehrteiligen Führung, hier aus zwei Walzen
36 und 37 bestehend, die in Richtung von Pfeilen 38 angetrieben sind, angeordnet sein kann.
Auch hier ergibt sich eine Verdichtung des Wickels 1 auf den Betrag a. Fig. 6 shows a
Fig. 7 zeigt die Anwendung eines erfindungsgemässen Dickenfühlers 39 im Umfeld einer Karde
40 mit nachgeschaltetem Kannensystem 41 zur Ablage von kardiertem Band 42. Karde und
Kannen weisen einen gemeinsamen mechanischen oder elektrischen Antrieb 43 und ein
Überwachungs- und Regelsystem 44 auf. Wie hier gezeigt, kann der Dickenfühler 39 im Bereiche
einer Einzugswalze 45 am Eingang zur Karde 40 vorgesehen und über eine Leitung 46
mit dem Überwachungs- und Regelsystem 44 verbunden sein.7 shows the use of a
Die Wirkungsweise der erfindungsgemässen Vorrichtung ist wie folgt:
Durch die unterschiedliche Dicke des bewegten Wickels 1 wird die Messwalze 3' mehr oder
weniger stark von der Führung 2 abgehoben. Dabei wird eine Bewegung der Messwalze 3'
über die Rollen 7, 8, den Wagen 11, die Stütze 12 und die Umlenkrolle 13 auf das Übertragungselement
14 übertragen, das dabei eine Schleife, die es im Bereiche der Umlenkrollen
13, 15, 16 bildet, vergrössert oder verkleinert. Durch die Bewegung des Übertragungselementes
wird ein Geber 47 im Wegmesssystem 22 mehr oder weniger ausgelenkt, was die Angabe
über die Dicke oder die Gleichmässigkeit des Wickels 1 liefert. Statt des Gebers 47 kann das
Wegmesssystem 22 aber auch berührungslos arbeiten.The operation of the device according to the invention is as follows:
Due to the different thickness of the moving roll 1, the measuring roller 3 'is more or less lifted off the
Bei der Anordnung mehrerer solcher Dickenfühler 26, 27, 28 nebeneinander, summieren sich
die Auslenkungen von drei Schleifen 48, 49, 50, so, dass sich an demjenigen Ende des Übertrangungselementes,
das am Wegmesssystem 32 befestigt ist, ein Signal ergibt, das der gemittelten
Dicke des Wickels 1 entspricht. Da alle Schleifen 48, 49, 50 von einer mittleren Auslenkung
auch bei einer Dicke Null des Wickels 1 ausgehen, werden sehr geringe Dicken auf einer
Messwalze mit grösseren Dicken auf einer anderen Messwalze verrechnet. Bei mehreren Dikkenfühlern
in Serieschaltung, wie aus der Fig. 3 bekannt, muss auch das Wegmesssystem 32
entsprechend geeicht werden.If several
