Description

Die Erfindung betrifft eine Walze, insbesondere eine Saugwalze einer Papiermaschine, die an mindestens einer Stirnseite einen eine Öffnung abdeckenden Deckel und ein Anzeigenpaneel aufweist.The invention relates to a roller, in particular a suction roll of a paper machine, which has at least one end face a lid covering an opening and a display panel.

Fig. 1 zeigt eine aus dem Stand der Technik bekannte Saugwalze 10 einer hier nicht näher dargestellten Papiermaschine. Die Saugwalze 10 weist an ihrer Stirnseite 11 ein Anzeigenpaneel 12 auf, das mit verschiedenen analogen Anzeigeeinrichtungen 13, 14 und 15 versehen ist. Das Anzeigenpaneel 12 ist in der Regel durch einen hier nicht näher dargestellten Deckel verdeckt. Bei geschlossenem Deckel können die Anzeigeeinrichtungen 13, 14 und 15 nicht abgelesen werden. Da zum Ablesen der Anzeigeeinrichtungen 13, 14 und 15 der relativ schwere Deckel geöffnet und wieder verschlossen werden muss, ist ein schnelles Ablesen im Vorübergehen nicht möglich. Da der Deckel in ein Scharnier 16 eingehängt ist, ist zum Öffnen des Deckels, insbesondere bei großen Walzendurchmessern, außerdem ein relativ hoher Platzbedarf erforderlich. Wenn man statt des Deckels eine transparente Haube vorsieht, dann verschmutzt die relativ große Haubenfläche schnell, so dass die Anzeigeeinrichtungen 13, 14 und 15 schlecht oder nur kurzzeitig ablesbar sind.Fig. 1 shows a known from the prior art suction roll 10 of a paper machine not shown here. The suction roller 10 has on its front side 11 on a display panel 12 which is provided with various analog display devices 13, 14 and 15. The display panel 12 is usually covered by a lid, not shown here. When the lid is closed, the display devices 13, 14 and 15 can not be read. Since for reading the display devices 13, 14 and 15 of the relatively heavy lid must be opened and closed again, a quick reading in passing is not possible. Since the lid is hung in a hinge 16, a relatively large amount of space is also required to open the lid, especially for large roll diameters. If you provide a transparent hood instead of the lid, then the relatively large hood surface contaminates quickly, so that the display devices 13, 14 and 15 are poor or only briefly read.

Eine Walze, welche der in Fig. 1 gezeigten Saugwalze entspricht, ist auch aus der EP 1 082 490 B1 bekannt.A roller which corresponds to the suction roller shown in FIG. 1 is also known from EP 1 082 490 B1.

Die Erfindung hat die Aufgabe eine Walze der eingangs genannten Art dahingehend zu verbessern, dass zukünftig die Anzeigeeinrichtungen ohne den Deckel öffnen zu müssen, abgelesen werden können.The invention has the object to improve a roller of the type mentioned in that future display devices without having to open the lid, can be read.

Die Erfindung löst die gestellte Aufgabe durch eine Walze der eingangs genannten Art, bei der erfindungsgemäß das Anzeigenpaneel am Deckel angeordnet ist. Folglich muss zum Ablesen der Anzeigeeinrichtungen der Deckel nicht mehr geöffnet werden. Die Anzeigeinstrumente können jetzt schnell im Vorübergehen abgelesen werden. Selbstverständlich kann das Anzeigenpaneel mit beliebig vielen Anzeigeeinrichtungen versehen sein.The invention solves the problem set by a roller of the type mentioned, in which according to the invention the display panel is arranged on the lid. consequently to read the display devices, the lid must not be opened. The gauges can now be quickly read in passing. Of course, the display panel can be provided with any number of display devices.

Wenn man für Wartungsarbeiten oder zum Verstellen eines Saugkastens ins Innere der Walze gelangen muss, kann der Deckel zum Öffnen der Öffnung verschwenkt werden. Um den Deckel auch bei beengten Platzverhältnissen öffnen zu können, kann der Deckel mittels zueinander paralleler Verbindungselemente verschwenkbar an der Walze angeordnet sein. Ein platzraubendes Drehscharnier ist somit nicht mehr erforderlich.If you need to get into the interior of the roller for maintenance or for adjusting a suction box, the lid can be pivoted to open the opening. In order to open the lid even in confined spaces, the lid can be arranged by means of mutually parallel connecting elements pivotally mounted on the roller. A space-consuming rotary hinge is therefore no longer required.

Alternativ ist es auch möglich den Deckel zum Öffnen der Öffnung parallel zur Öffnung zu verschieben. Dann kann der Deckel ebenfalls bei beengten Platzverhältnissen problemlos geöffnet werden. Damit der Deckel parallel zur Öffnung verschoben werden kann, können Stangenführungen, Kettenführungen, Kulissenführungen und andere dem Fachmann bekannte Konstruktionen verwendet werden.Alternatively, it is also possible to move the lid to open the opening parallel to the opening. Then the lid can also be easily opened in confined spaces. In order that the cover can be moved parallel to the opening, rod guides, chain guides, slide guides and other constructions known to those skilled in the art can be used.

In einer weiteren alternativen Ausführungsform ist es möglich, dass der Deckel an die mindestens eine Stirnseite angeschraubt ist. Da ein in der Walze untergebrachter Saugkasten in der Regel nicht verstellt werden muss und auch Formatverstellungen einer Materialbahn nur sehr selten durchgeführt werden müssen, ist es kaum erforderlich den Deckel von der Walze zu lösen. Die Anzeigeeinrichtungen können dann durch im Deckel vorgesehene Ausschnitte überwacht werden.In a further alternative embodiment, it is possible that the lid is screwed to the at least one end face. Since a suction box accommodated in the roll usually does not have to be adjusted and also format adjustments of a material web need only be carried out very rarely, it is hardly necessary to detach the cover from the roll. The display devices can then be monitored by cutouts provided in the lid.

In einer Weiterbildung der Erfindung kann das Anzeigenpaneel von einem Rahmen umgeben sein. Das Anzeigenpaneel kann unabhängig vom Walzendurchmesser immer dieselben Abmessungen aufweisen. Der das Anzeigenpaneel umgebende Rahmen kann jedoch an den jeweiligen Walzendurchmesser angepasst werden. Der Rahmen kann als Blechteil oder als tiefgezogenes Kunststoffteil gefertigt werden.In a further development of the invention, the display panel may be surrounded by a frame. The display panel can always have the same dimensions regardless of the roll diameter. However, the frame surrounding the display panel can be adapted to the respective roll diameter. The frame can be manufactured as a sheet metal part or as a deep-drawn plastic part.

Wenn der Rahmen aus Kunststoff gefertigt wird, kann die Tiefziehform flexibel an den Durchmesser des jeweils zu fertigenden Rahmen angepasst werden. Zu diesem Zweck kann die Tiefziehform aus konzentrischen Ringelementen aufgebaut sein, die je nach gewünschtem Durchmesser zusammengestellt werden.If the frame is made of plastic, the thermoforming mold can be flexibly adapted to the diameter of the respective frame to be produced. For this purpose, the thermoforming mold can be constructed of concentric ring elements, which are assembled according to the desired diameter.

Das Anzeigenpaneel kann digitale Anzeigeeinrichtungen, wie beispielsweise LED- oder LCD-Anzeigen, aufweisen. Digitale Anzeigeeinrichtungen sind leichter ablesbar, störungsunempfindlicher und platzsparender als analoge Anzeigeeinrichtungen. Weil digitale Anzeigeeinrichtungen platzsparend angeordnet werden können, ermöglichen sie die Anordnung von mehr Anzeigeeinrichtungen als bisher.The display panel may include digital display devices such as LED or LCD displays. Digital display devices are easier to read, less sensitive to interference and space-saving than analog display devices. Because digital display devices can be arranged to save space, they allow the arrangement of more display devices than before.

Um ein unerwünschtes Verschmutzen des Deckels und der unter der Deckeloberfläche hinter transparenten Abdeckungen angeordneten Anzeigeeinrichtungen zu vermeiden, können Randbereiche des Deckels abgeschrägt sein. Dann können Verunreinigungen gut vom Deckel abfließen, so dass die Anzeigeeinrichtungen jederzeit gut ablesbar sind.In order to avoid undesirable fouling of the lid and arranged under the lid surface behind transparent covers display devices, edge portions of the lid can be chamfered. Then contaminants can drain well from the lid, so that the display devices are easy to read at any time.

Alternativ oder zusätzlich zu den abgeschrägten Randbereichen des Deckels können die auf dem Anzeigenpaneel angeordneten Anzeigeeinrichtungen durch eine mit einem Deckel verschließbare und öffenbare Inspektionsöffnung abgelesen werden. Zum Ablesen der Anzeigeeinrichtungen kann der Deckel verschwenkt werden. Nach dem Ablesen der Anzeigeeinrichtungen kann der Deckel wieder über die Inspektionsöffnung zurückgeschwenkt werden. Der Deckel schützt somit die Inspektionsöffnung vor unerwünschten Verunreinigungen.As an alternative or in addition to the beveled edge regions of the lid, the display devices arranged on the display panel can be read through an inspection opening which can be closed with a lid and opened. For reading the display devices, the lid can be pivoted. After reading the display devices, the lid can be swung back over the inspection opening. The lid thus protects the inspection opening from unwanted contamination.

Vorzugsweise sind die Anzeigeeinrichtungen digitale oder analoge Anzeigeeinrichtungen.Preferably, the display devices are digital or analog display devices.

Die auf den Anzeigeeinrichtungen dargestellten Messwerte und Messdaten können elektronisch erfasst und dargestellt werden. Durch die elektronische Erfassung der Messwerte können diese an mehreren Orten gleichzeitig dargestellt werden. Außer der Darstellung der Messwerte auf dem die Walze an ihrer Stirnseite abdeckenden Deckel können diese an einer Stuhlung der Papiermaschine in ergonomisch sinnvoller Höhe an einer spritzgeschützten Stelle durch eine zusätzliche Anzeigeeinrichtung dargestellt werden. Außerdem können die Messwerte in einer Leitwarte oder in einem mobilen Handanzeigenpaneel dargestellt werden.The measured values and measured data displayed on the display devices can be recorded and displayed electronically. By electronically recording the measured values, these can be displayed simultaneously in several places. Except the representation of the measured values on the cover covering the roller on its front side, these can be represented on a paper machine frame in an ergonomically sensible height at an injection-protected point by an additional display device. In addition, the measured values can be displayed in a control room or in a mobile hand-held display panel.

Damit die Anzeigeeinrichtungen vor Beschädigungen geschützt sind, kann das Anzeigenpaneel mit einem Rammschutz versehen sein.So that the display devices are protected from damage, the display panel can be provided with a ramming protection.

Zusätzlich oder alternativ zum Rammschutz kann das Anzeigenpaneel mit einer flexiblen Oberfläche ausgestattet sein.Additionally or alternatively to the ramming protection, the display panel can be equipped with a flexible surface.

In einer weiteren Ausgestaltung der Erfindung kann das Anzeigenpaneel preiswert aus einem tiefgezogenen Blech oder aus Kunststoff gefertigt sein.In a further embodiment of the invention, the display panel can be made inexpensively from a deep-drawn sheet metal or plastic.

Sowohl die Blechvariante als auch die Kunststoffvariante ermöglichen es, das Anzeigenpaneel als eine Sandwichkonstruktion zu fertigen. Durch die Sandwichkonstruktion ist das Anzeigenpaneel robust gegen äußere Stöße, Schläge und dergleichen.Both the sheet metal version and the plastic version make it possible to manufacture the display panel as a sandwich construction. Due to the sandwich construction, the display panel is robust against external shocks, impacts and the like.

Aus Gründen der Sicherheit kann der Deckel mit Griffschalen versehen sein, die mit teilweise abgedeckten Mulden versehen sind. Ein Bedienpersonal kann somit die Griffschalen zum Öffnen oder zum Verschließen des Deckels hintergreifen. Weil die Mulden teilweise verdeckt sind, verschmutzen die Griffschalen kaum. Außerdem verhindern die Griffschalen ein Verhaken von Kleidungsstücken, so dass sie Unfälle vermeiden.For reasons of safety, the lid may be provided with handles which are provided with partially covered troughs. An operator can thus engage behind the handles for opening or closing the lid. Because the hollows are partially covered, the handles scarcely pollute. In addition, the handles prevent hooking garments so that they avoid accidents.

Der Deckel kann mit einer Aussparung zur Durchführung von Schläuchen und/oder Rohren und/oder Kabeln und dergleichen versehen sein. Auf diese Weise können Flansche an der Stirnseite der Walze zum Anschluss der Rohre und/oder Schläuche entfallen. Dadurch werden der Montageaufwand und das Leckagerisiko deutlich reduziert.The lid may be provided with a recess for the passage of hoses and / or pipes and / or cables and the like. In this way, flanges on the front side of the roller for connecting the tubes and / or hoses omitted. As a result, the installation effort and the risk of leakage are clear reduced.

Die Schläuche und/oder Rohre und/oder Kabel können zu einem Bündel zusammengefasst sein. Durch die Bündelung der Schläuche und/oder Rohre und/oder Kabel können die Leitungen geordnet geführt werden, wodurch Wartungsarbeiten erleichtert werden. Um die Schläuche und/oder Rohre und/oder Kabel zu bündeln, können handelsübliche Kabelkanäle verwendet werden.The hoses and / or pipes and / or cables can be combined to form a bundle. By bundling the hoses and / or pipes and / or cables, the lines can be sorted out, making maintenance easier. To bundle the hoses and / or pipes and / or cables, commercially available cable ducts can be used.

Nachfolgend werden verschiedene Ausführungsbeispiele anhand der beiliegenden Zeichnungen näher erläutert.Various exemplary embodiments will be explained in more detail below with reference to the accompanying drawings.

Fig. 2 zeigt eine Walze 20, die eine Saugwalze einer hier nicht näher dargestellten Papiermaschine ist. Die Walze 20 weist an ihrer Stirnseite eine Öffnung 21 auf. Die Öffnung 21 kann durch einen Deckel 22 geöffnet und verschlossen werden. Auf dem Deckel 22 ist ein Anzeigenpaneel 23 angeordnet. Das Anzeigenpaneel 23 ist mit Anzeigeeinrichtungen 24 versehen. Mit den Anzeigeeinrichtungen 24 werden während des Betriebes aufgenommene Messwerte dargestellt, wie beispielsweise Unterdrücke, ein Vakuum über der Breite einer Materialbahn, Temperaturen, Drehzahlen, elektrische Messgrößen und dergleichen. Da das Anzeigenpaneel 23 mit den Anzeigeeinrichtungen 24 außen auf dem Deckel 22 angebracht ist, können die Anzeigeeinrichtungen 24 auch abgelesen werden, wenn der Deckel 22 die Öffnung 21 freigibt, weil Wartungsarbeiten im Inneren der Walze 20 ausgeführt oder, weil ein hier nicht erkennbarer Saugkasten verstellt werden muss. Die Ausrichtung der Anzeigeeinrichtungen 24 ist von der Stellung des Saugkastens unabhängig.Fig. 2 shows a roller 20 which is a suction roll of a paper machine not shown here. The roller 20 has an opening 21 on its front side. The opening 21 can be opened and closed by a cover 22. On the lid 22, a display panel 23 is arranged. The display panel 23 is provided with display devices 24. With the display devices 24 recorded during operation, measured values are shown, such as negative pressures, a vacuum over the width of a web, temperatures, speeds, electrical measurements and the like. Since the display panel 23 is mounted with the display devices 24 on the outside of the lid 22, the display devices 24 can also be read when the cover 22 releases the opening 21, because maintenance is carried out inside the roller 20 or because a suction box, not recognizable here, is adjusted must become. The orientation of the indicators 24 is independent of the position of the suction box.

Damit die Öffnung 21 auch bei beengten Platzverhältnissen geöffnet werden kann, kann der Deckel 22 parallel zur Öffnung 21 verschoben werden (siehe Fig. 3). Um den Deckel 22 parallel zur Öffnung 21 verschieben zu können, können hier nicht näher dargestellte Stangenführungen, Kettenführungen, Kulissenführungen und dergleichen verwendet werden.Thus, the opening 21 can be opened even in confined spaces, the lid 22 can be moved parallel to the opening 21 (see Fig. 3). In order to move the cover 22 parallel to the opening 21, not shown rod guides, chain guides, slotted guides and the like can be used here.

In einer weiteren bevorzugten Ausführungsform ist es möglich, dass der Deckel 22 mittels zueinander paralleler Verbindungselemente 40 mit der Walze 20 verbunden ist (siehe Fig. 4). Durch die zueinander parallel angeordneten Verbindungselemente 40 kann der Deckel 22 beim Freigeben der Öffnung 21 von der Öffnung 21 weggeschenkt werden und zum Verschließen der Öffnung 21 zur Öffnung 21 hingeschwenkt werden. Die parallel zueinander angeordneten Verbindungselemente 40 ermöglichen ebenfalls ein Öffnen der Öffnung 21 bei beengten Platzverhältnissen. Beim Verschwenken des Deckels 22 muss dieser nur um einen minimalen Weg, welcher der Länge der Verbindungselemente 40 entspricht, von der Öffnung 21 abgehoben werden. Durch die in den Fign. 3 und 4 dargestellten Konstruktionen zum Öffnen und zum Verschließen der Öffnung 21 muss der Deckel 22 nicht mehr mit einem platzraubenden Drehscharnier an die Walze 20 angebunden werden.In a further preferred embodiment, it is possible for the cover 22 to be connected to the roller 20 by means of mutually parallel connecting elements 40 (see FIG. 4). By connecting elements 40 arranged parallel to one another, the cover 22 can be dispensed away from the opening 21 when the opening 21 is released and can be pivoted to close the opening 21 to the opening 21. The mutually parallel connecting elements 40 also allow opening of the opening 21 in confined spaces. When pivoting the lid 22, this only has to be lifted off the opening 21 by a minimum distance corresponding to the length of the connecting elements 40. By the in Figs. 3 and 4 shown constructions for To open and close the opening 21, the lid 22 no longer has to be connected to the roller 20 with a space-consuming rotary hinge.

In einer weiteren bevorzugten Ausführungsform ist es möglich, den Deckel 22 auf die Öffnung 21 aufzuschrauben. Dies ist eine sehr preiswerte Alternative, die ebenfalls sehr sinnvoll ist, weil der in der Walze 20 untergebrachte Saugkasten üblicherweise nach der Inbetriebnahme der Walze 20 beziehungsweise der Papiermaschine nicht mehr verstellt werden muss. Auch Formatverstellungen, die im Inneren der Walze 20 durchgeführt werden müssen, sind nur sehr selten erforderlich. Folglich muss der Deckel 22 nur in ganz seltenen Fällen von der Öffnung 21 abgeschraubt werden.In a further preferred embodiment, it is possible to screw the lid 22 onto the opening 21. This is a very inexpensive alternative, which is also very useful, because the accommodated in the roller 20 suction box usually does not need to be adjusted after the commissioning of the roller 20 and the paper machine. Even format adjustments that must be performed inside the roller 20, are required only very rarely. Consequently, the lid 22 must be unscrewed from the opening 21 only in very rare cases.

Die Fign. 5 und 6 zeigen einen Deckel 50 und 60 mit jeweils einem Anzeigenpaneel 51 und 61, die jeweils Anzeigeeinrichtungen 52 und 62 aufweisen. Die Anzeigeeinrichtungen 52, 62, wie auch die Anzeigeeinrichtungen 24 aus Fig. 2, können vorteilhafterweise LED- oder LCD-Anzeigen sein. Da die digitalen Anzeigeeinrichtungen 24, 52 und 62 platzsparend angeordnet werden können, können durch ihre Verwendung mehr Informationen dargestellt werden als bisher bei der Verwendung von analogen Anzeigeeinrichtungen. Außerdem sind die digitalen Anzeigeeinrichtungen 24, 52 und 62 leichter ablesbar, störungsunempfindlicher und platzsparender als analoge Anzeigeeinrichtungen.The Fign. FIGS. 5 and 6 show a lid 50 and 60 each having a display panel 51 and 61, each having indicators 52 and 62, respectively. The display devices 52, 62, as well as the display devices 24 of FIG. 2, may advantageously be LED or LCD displays. Since the digital display devices 24, 52 and 62 can be arranged in a space-saving manner, their use allows more information to be displayed than hitherto when analog display devices were used. In addition, the digital display devices 24, 52 and 62 are easier to read, less sensitive to interference and space-saving than analog display devices.

Die Anzeigenpaneele 51 und 61 können unabhängig von Durchmesser einer Walze 53 und 63 immer dieselben Abmessungen aufweisen. Somit können die Anzeigenpaneele 51 und 61 in Walzen mit unterschiedlichen Durchmessern eingebaut werden. Ein das Anzeigenpaneel 51 umgebender Rahmen 54 und ein das Anzeigenpaneel 61 umgebender Rahmen 64 kann jedoch an den jeweiligen Durchmesser der Walze 53 und 63 angepasst werden. Die Rahmen 54 und 64 können als Blechteil oder als tiefgezogenes Kunststoffteil gefertigt werden.The display panels 51 and 61 may always have the same dimensions regardless of the diameter of a roller 53 and 63. Thus, the display panels 51 and 61 can be installed in rollers of different diameters. However, a frame 54 surrounding the display panel 51 and a frame 64 surrounding the display panel 61 may be adapted to the respective diameter of the roller 53 and 63. The frame 54 and 64 can be manufactured as sheet metal part or as a deep-drawn plastic part.

Die Deckel 50 und 60 sind jeweils mit einer Aussparung 56 und 66 versehen, durch die Schläuche 57 und 67 geführt werden. Durch die Aussparungen 56 und 66 können seither erforderliche Flansche an der Stirnseite der Walze 20 zum Anschluss der Schläuche 57 und 67 entfallen. Dadurch kann der Montageaufwand und das Leckagerisiko reduziert werden.The covers 50 and 60 are each provided with a recess 56 and 66 through which tubes 57 and 67 are guided. Through the recesses 56 and 66 can since then required flanges on the front side of the roller 20 for connecting the tubes 57 and 67 accounts. As a result, the installation effort and the risk of leakage can be reduced.

Die Schläuche 57 und 67 sind zu einem Bündel zusammengefasst. Durch die Bündelung der Schläuche 57 und 67 wird eine geordnete Leitungsführung erzielt, wodurch durchzuführende Wartungsarbeiten erleichtert werden. Zum Bündeln der Schläuche 57 und 67 können handelsübliche Kabelkanäle verwendet werden.The hoses 57 and 67 are combined into a bundle. By bundling the tubes 57 and 67 an orderly routing is achieved, making maintenance to be performed easier. For bundling the tubes 57 and 67 commercially available cable channels can be used.

Der Rahmen 54 des Deckels 50 und der Rahmen 64 des Deckels 60 weisen jeweils abgeschrägte Randbereiche 55 und 65 auf. Durch die abgeschrägten Randbereiche 55 und 65 können Verunreinigungen gut von den Deckeln 50 und 60 abfließen. Somit sind die Anzeigeeinrichtungen 52 und 62 jederzeit gut ablesbar.The frame 54 of the lid 50 and the frame 64 of the lid 60 each have beveled edge portions 55 and 65. By the chamfered edge portions 55 and 65, contaminants can flow well from the covers 50 and 60. Thus, the display devices 52 and 62 are always easy to read.

Fig. 7 zeigt einen Deckel 70. Nicht näher erkennbare Anzeigeeinrichtungen, die auf einem ebenfalls nicht erkennbaren Anzeigenpaneel angeordnet sind, können durch eine Inspektionsöffnung 71 abgelesen werden. Die Inspektionsöffnung 71 kann mit einem Deckel 72 verschlossen oder geöffnet werden. Zu diesem Zweck kann der Deckel 72 in Richtung eines Pfeiles 73 hin- und hergeschwenkt werden. Folglich vermeidet der Deckel 72 eine Verschmutzung der Inspektionsöffnungen 71, sodass die Anzeigeeinrichtungen jederzeit gut abgelesen werden können.Fig. 7 shows a lid 70. Indeterminate display devices which are arranged on a likewise not recognizable display panel can be read through an inspection opening 71. The inspection opening 71 can be closed or opened with a cover 72. For this purpose, the lid 72 can be swung back and forth in the direction of an arrow 73. Consequently, the cover 72 avoids contamination of the inspection openings 71, so that the display devices can be read well at any time.

Die Anzeigenpaneele 23, 51 und 61 können zum Schutz der Anzeigeeinrichtungen 24, 52 und 62 vor Beschädigungen mit einem Rammschutz versehen sein.The display panels 23, 51 and 61 may be provided to protect the display devices 24, 52 and 62 from damage with a crash protection.

Zusätzlich oder alternativ zum Rammschutz können die Anzeigenpaneele 23, 51 und 61 mit einer flexiblen Oberfläche versehen sein.In addition or as an alternative to the crash protection, the display panels 23, 51 and 61 may be provided with a flexible surface.

Um die Anzeigenpaneele 23, 51 und 61 preiswert herstellen zu können, können sie aus einem tiefgezogenen Blech oder aus Kunststoff gefertigt sein. Die Anzeigenpaneele 23, 51 und 61 können aus einer Sandwichkonstruktion gefertigt sein. Dadurch sind die Anzeigenpaneele 23, 51 und 61 robust gegen äußere auf sie einwirkende Stöße, Schläge und dergleichen.In order to produce the display panels 23, 51 and 61 inexpensively, they can be made of a deep-drawn sheet metal or plastic. The display panels 23, 51 and 61 can be made of a sandwich construction be. Characterized the display panels 23, 51 and 61 are robust against external shocks, blows and the like acting on them.

Aus Sicherheitsgründen können die Deckel 22, 50, 60 und 70 mit Griffschalen versehen sein, die teilweise abgedeckte Mulden aufweisen. Zum Öffnen oder zum Verschließen der Deckel 22, 50, 60 und 70 kann ein Bedienpersonal die Griffschalen hintergreifen. Da die Mulden teilweise verdeckt sind, verschmutzen sie kaum. Ferner verhindern die Griffschalen, dass sich Kleidungsstücke verhaken können, wodurch Unfälle vermieden werden.For safety reasons, the covers 22, 50, 60 and 70 may be provided with handle shells having partially covered wells. To open or close the lid 22, 50, 60 and 70, an operator can reach behind the handles. Since the hollows are partially covered, they hardly pollute. Furthermore, the handles prevent garments from getting caught, thereby avoiding accidents.

Die auf den Anzeigeeinrichtungen 24, 52 und 62 dargestellten Messwerte werden elektronisch erfasst. Die elektronische Erfassung der Messwerte ermöglicht ihre Darstellung an mehreren Orten gleichzeitig. Außer der Darstellung der Messwerte auf den Deckeln 22, 50, 60 und 70 können diese an einer Stuhlung der Papiermaschine angezeigt werden. Außerdem ist es möglich, die Messwerte in einer Leitwarte oder in einem mobilen Handanzeigenpaneel darzustellen.The measured values displayed on the display devices 24, 52 and 62 are detected electronically. The electronic acquisition of the measured values enables their representation in several places at the same time. Apart from the representation of the measured values on the covers 22, 50, 60 and 70, these can be displayed on a pulp of the paper machine. In addition, it is possible to display the measured values in a control room or in a mobile hand-held display panel.
