Description

Die Erfindung betrifft das Gebiet des Streichens von Faserstoffbahnen. Dabei kommen Papierbahnen, Kartonbahnen oder andere Bahnen in Betracht.The invention relates to the field of coating fibrous webs. In this case, paper webs, board webs or other webs into consideration.

Es gibt eine Vielzahl von Systemen zum Streichen einer Faserstoffbahn aus Papier oder dergleichen. Siehe zum Beispiel DE 44 02 744 A1 , DE 44 02 108 A1 , DE 44 01 737 A1 , DE- A1 196 000 46 .There are a variety of systems for coating a fibrous web of paper or the like. See for example DE 44 02 744 A1 . DE 44 02 108 A1 . DE 44 01 737 A1 . DE-A1 196 000 46 ,

Solche Anlagen können auf unterschiedliche Weise aufgebaut sein. So kann die Anlage einer Walze umfassen, die im Betrieb von der Faserstoffbahn umschlungen ist, rotiert, und dabei die Faserstoffbahn mitnimmt. Die Streichfarbe wird von einer Auftragseinrichtung direkt auf die Faserstoffbahn aufgetragen.Such systems can be constructed in different ways. Thus, the system may comprise a roller, which is looped around in operation by the fibrous web, rotating, thereby entraining the fibrous web. The coating color is applied directly to the fibrous web by an applicator.

Die Streichfarbe kann aber auch in einem indirekten Verfahren zunächst auf die Mantelfläche einer umlaufenden Walze aufgetragen und von der Mantelfläche sodann an die laufende Faserstoffbahn abgegeben werden.The coating color can also be applied in an indirect process initially on the lateral surface of a rotating roller and then discharged from the lateral surface to the moving fibrous web.

Es gibt verschiedene Arten von Auftragseinrichtungen. Im vorliegenden Falle sollen vor allem Düsenauftragswerke betrachtet werden, bei welchen aus einer maschinenbreiten Düse ein freier Strahl des Streichmediums, beispielsweise Streichfarbe aufgebracht wird, entweder im direkten oder im indirekten Verfahren.There are different types of applicators. In the present case, in particular nozzle applicators are to be considered, in which from a machine-wide nozzle, a free jet of the coating medium, such as coating color is applied, either in the direct or in the indirect process.

In der Auftragseinrichtung ist oftmals eine Rakeleinrichtung vorgesehen. Auch hierfür kommen unterschiedliche Bauarten in Betracht. Üblicherweise verwendet man eine Rakeleinrichtung mit einer Rakelklinge, oder einer Rakelleiste oder einem rotierenden Rakelstab. Auch so genannte Luftmesser kommen zum Einsatz.In the applicator often a doctor device is provided. Again, different types come into consideration. Usually, a squeegee device with a doctor blade, or a squeegee bar or a rotary squeegee bar is used. Even so-called air knives are used.

Die Auftragseinrichtung erstreckt sich über die gesamte Breite der Maschine. Sie ist von einem Tragbalken getragen. Der Tragbalken ist verschwenkbar, und zwar aus einer abgefahrenen oder Ruheposition, in welcher die eigentliche Auftragseinrichtung von der Mantelfläche der Walze einen größeren Abstand hat, in eine angestellte oder Arbeitsposition, in welcher sich die Auftragseinrichtung nahe bei der Faserstoffbahn oder bei der Mantelfläche der Walze befindet, um die Streichfarbe oder ein anderes Auftragsmedium aufzutragen.
Der Tragbalken ist ebenso in umgekehrter Reihenfolge, also von der angestellten in die abgefahrene Position verfahrbar.The applicator extends over the entire width of the machine. It is supported by a stringers. The support beam is pivotable, namely from a worn or rest position in which the actual application device from the lateral surface of the roller has a greater distance, in a salaried or working position in which the applicator is close to the fibrous web or the lateral surface of the roller to apply the coating or other application medium.
The support beam is also in reverse order, so moved from the salaried in the worn position.

Unterhalb des Tragbalkens mit der von ihm getragenen Auftragseinrichtung befindet sich ein Laufsteg. Während der Tragbalken verfahrbar ist - im Allgemeinen um eine horizontale Achse verschwenkbar -, so ist der Laufsteg ortsfest. Beim Übergang zwischen der Ruheposition und der Arbeitsposition beziehungsweise umgekehrt findet somit eine Relativbewegung zwischen diesen beiden Bauteilen - Tragbalken einerseits und Laufsteg andererseits - statt. Hierbei besteht eine große Gefahr für das Bedienungspersonal, sofern sich dieses auf dem Laufsteg befindet. Eine Schwenkbewegung des Tragbalkens kann sehr plötzlich eintreten. Kommt es nämlich zu einer Produktionsunterbrechung, beispielsweise durch ein Abreißen der Papierbahn oder eine sonstige Störung, so wird die Auftragseinrichtung mit dem Tragbalken von der Walze weggeschwenkt, in Richtung auf den Laufsteg. Dabei besteht für das Personal Quetschgefahr zwischen der Auftragseinrichtung und dem Laufsteg.Below the supporting beam with the applicator carried by him is a catwalk. While the support beam is movable - generally pivotable about a horizontal axis -, so the catwalk is stationary. In the transition between the rest position and the working position or vice versa thus finds a relative movement between these two components - support beams on the one hand and catwalk on the other hand - instead. There is a great danger to the operating personnel, if this is on the catwalk. A pivoting movement of the support beam can occur very suddenly. If, for example, there is a stoppage of production, for example due to a tearing off of the paper web or any other disturbance, then the applicator device is pivoted away from the roller with the support beam, in the direction of the catwalk. There is a risk of crushing between the job application and the catwalk.

Um diese Gefahrenstelle abzusichern, werden bisher Schutzzäune um die Auftragseinrichtung herum angeordnet, die einen Eintritt oder einen Eingriff in die Gefahrenzonen nicht zulassen. Auch hat man schon den kritischen Raum durch ein Tuch abgedeckt. Führt der Tragbalken eine Abschwenkbewegung aus, so wird das Tuch gestaucht oder in Falten gelegt, und bietet dann keinen zuverlässigen Schutz für das Bedienungspersonal gegen Quetschen.In order to safeguard this danger point, so far protective fences are arranged around the applicator around, which does not allow entry or intervention in the danger zones. Also you have already covered the critical space by a cloth. If the stringers deflect, the cloth will be squashed or wrinkled, and will not provide reliable protection for the operator against squashing.

Auch könnte man an zusätzliche Steuerungen denken, um jegliche Schwenkvorgänge zuverlässig und sicher zu betreiben. Derartige steuertechnische Mittel mit Hardware und Software bedeuten jedoch einen hohen Aufwand und sind daher kostenintensiv.Also, one could think of additional controls to operate any panning operations reliably and safely. Such tax technical However, means with hardware and software mean a lot of effort and are therefore costly.

Der Erfindung liegt die Aufgabe zugrunde, eine gemäß dem Oberbegriff gestaltete Anlage derart zu gestalten, dass das Bedienungspersonal gegen Unfälle zufolge von Schwenkbewegungen des Tragbalkens mit der darauf befindlichen Auftragseinrichtung zuverlässig geschützt wird.The invention has for its object to design a designed according to the preamble system such that the operator is reliably protected against accidents by pivotal movements of the support beam with the applicator device located thereon.

Diese Aufgabe wird mit einer Anlage gemäß Anspruch 1 gelöst.This object is achieved with a system according to claim 1.

Der Kerngedanke besteht darin, einen gespannt bzw. straff gehaltenen Vorhang vorzusehen, der als mechanische Schutzeinrichtung wirkt. Erfindungsgemäß ist der Vorhang mit seinem oberen Ende an den Tragbalken angeschlossen und folgt diesem bei dessen Schwenkbewegung. Der Vorhang ist zu jedem Zeitpunkt gespannt. Er ist somit zu keinem Zeitpunkt gefaltet, sondern stellt eine positive Absperrung gegen jegliches Eingreifen in die Gefahrenzone dar. Die Lösung ist somit zuverlässig bezüglich der Sicherheit des Bedienungspersonales oder einer sonstigen sich dort befindlichen Person. Sie ist außerordentlich einfach im Aufbau, nicht störanfällig und kostengünstig. Irgendwelche Steuerungseinrichtungen sind entbehrlich.The core idea is to provide a taut or held curtain that acts as a mechanical protection device. According to the invention, the curtain is connected with its upper end to the support beam and follows this in its pivoting movement. The curtain is always curious. It is therefore not folded at any time, but represents a positive barrier against any intervention in the danger zone. The solution is thus reliable in terms of the safety of the operator or any other person located there. It is extremely simple in construction, not prone to failure and cost-effective. Any control devices are unnecessary.

Unter der Ausdrucksweise "Vorhang" wird jegliches flächige, biegeschlaffe Gebilde verstanden. Es kann sich dabei um ein Tuch handeln. Das Tuch kann aus Stoff oder aus Gummi oder aus sonstigem Material sein. Es kann gelocht oder geschlitzt sein. Auch ist ein dünnes Blech denkbar, oder ein Netz. Denkbar ist auch ein sich überlappendes und in seiner Höhe ausfahrbares Blech.The term "curtain" is understood to mean any flat, pliable structure. It can be a cloth. The cloth may be made of cloth or of rubber or other material. It can be perforated or slotted. Also a thin sheet metal is conceivable, or a net. It is also conceivable overlapping and extendable in height sheet.

Eine vorteilhafte Ausführung kann darin bestehen, dass der Vorhang durch eine an seinem unteren Ende angreifende Spanneinrichtung gespannt gehalten ist.An advantageous embodiment may consist in that the curtain is held under tension by a tensioning device acting on its lower end.

Als Spanneinrichtung ist in erster Linie an ein Gewicht zu denken, das an die Unterkante des Vorhangs angehängt wird. Auch könnte eine Feder an der Unterkante angreifen. Der Vorhang kann auch über eine Umlenkrolle geführt sein.As a tensioning device is primarily to think of a weight that is attached to the lower edge of the curtain. Also, a spring could attack on the lower edge. The curtain can also be guided over a deflection roller.

Schließlich kann die Spanneinrichtung ganz einfach darin liegen, dass der Vorhang ein genügend großes Eigengewicht hat, so dass er ohne weiteres Zutun in einer Vertikalebene herabhängt. Es könnte dann der Fall sein, wenn man als Vorhang beispielsweise einen ausgedienten Papiermaschinenfilz verwendet.Finally, the tensioning device can simply be that the curtain has a sufficiently high dead weight so that it hangs down in a vertical plane without any further action. It could be the case, for example, when using a worn paper machine felt as a curtain.

Die Erfindung sowie der Stand der Technik sind anhand der Zeichnung näher erläutert. Darin ist im Einzelnen Folgendes dargestellt:

Figur 1
zeigt eine erste Ausführungsform einer Anlage gemäß der Erfindung mit der Auftragseinrichtung in Arbeitsposition.
Figur 2
zeigt den Gegenstand von Figur 1 mit der Auftragseinrichtung in Ruheposition.
Figur 3
zeigt eine zweite Ausführungsform einer Anlage gemäß der Erfindung mit der Auftragseinrichtung in Arbeitsposition.
Figur 4
zeigt den Gegenstand von Figur 3 mit der Auftragseinrichtung in Ruheposition.
Figur 5
zeigt eine bekannte Anlage mit der Auftragseinrichtung in Arbeitsposition.
Figur 6
zeigt die bekannte Anlage gemäß Figur 5 mit der Auftragseinrichtung in Ruheposition.
The invention and the prior art are explained in more detail with reference to the drawing. It details the following:
FIG. 1
shows a first embodiment of a plant according to the invention with the applicator in working position.
FIG. 2
shows the item of FIG. 1 with the applicator in rest position.
FIG. 3
shows a second embodiment of a plant according to the invention with the applicator in working position.
FIG. 4
shows the item of FIG. 3 with the applicator in rest position.
FIG. 5
shows a known system with the applicator in working position.
FIG. 6
shows the known system according to FIG. 5 with the applicator in rest position.

Die Anlage gemäß Figur 1 umfasst eine Walze 1, die von einer laufenden Faserstoffbahn 2 aus Papier umschlungen ist.The system according to FIG. 1 comprises a roller 1, which is looped by a running fibrous web 2 of paper.

Man erkennt ferner eine Auftragseinrichtung 3. Diese weist eine maschinenbreite Auftragslippe 4 auf. Die Auftragseinrichtung 3 ist von einem Tragbalken 5 getragen. Der Tragbalken 5 ist mittels eines Schwenkhebels 6 um eine horizontale Schwenkachse 7 verschwenkbar.Furthermore, an application device 3 can be seen. This has a machine-wide application lip 4. The applicator 3 is supported by a support beam 5. The support beam 5 is pivotable about a horizontal pivot axis 7 by means of a pivoting lever 6.

Unterhalb des Tragbalkens 5 und seitlich versetzt gegen diesen befindet sich ein Laufsteg 8 für das Bedienpersonal der Anlage bzw. der Streicheinrichtung.Below the support beam 5 and laterally offset against this is a catwalk 8 for the operator of the system or the coating device.

Es ist ein flächiger, biegeschlaffer Vorhang 9 vorgesehen. Dieser ist mit seinem oberen Ende am Tragbalken 5 befestigt. An seinem unteren Ende greift mindestens ein Gewicht 10 an. Dabei ist der Vorhang zwischen zwei Rollen 11, 12 geführt.It is a flat, limp curtain 9 provided. This is fastened with its upper end to the support beam 5. At its lower end at least one weight 10 attacks. The curtain between two rollers 11, 12 is guided.

Der Vorhang erstreckt sich über die gesamte Breite der Maschine. Auch eine geringere Erstreckung als über die gesamte Breite wäre denkbar.The curtain extends over the entire width of the machine. Even a smaller extension than over the entire width would be conceivable.

Der Auftragseinrichtung 3 ist - in Umlaufrichtung der Walze 1 gesehen - eine Rakeleinrichtung 13 nachgeschaltet. Diese umfasst eine Rakelklinge 14, ferner ein Leitblech 15 zum Abführen des abgerakelten Überschusses von Streichfarbe.The applicator 3 is - seen in the direction of rotation of the roller 1 - a doctor device 13 downstream. This comprises a doctor blade 14, further a baffle 15 for discharging the scraped-off excess of coating color.

Während des Betriebes läuft die Walze 1 um, im vorliegenden Falle im Uhrzeigersinn. Die Papierbahn 2 bewegt sich in Richtung des Pfeils. Ein maschinenbreiter Strahl wird mittels der Düsen- Auftragseinrichtung 3 gegen die Papierbahn 2 gerichtet. Die Rakeleinrichtung 13 rakelt einen gewissen Überschuss des aufgebrachten Streichfarbenfilms ab, so dass ein gleichmäßiger Film nach der Rakeleinrichtung 13 auf der Papierbahn 2 verbleibt.During operation, the roller 1 is running, clockwise in the present case. The paper web 2 moves in the direction of the arrow. A machine-wide beam is directed against the paper web 2 by means of the nozzle applicator 3. The squeegee device 13 strips off a certain excess of the applied coating color film, so that a uniform film remains behind the squeegee device 13 on the paper web 2.

Figur 2 veranschaulicht die Ruheposition des Tragbalkens 5. Dieser ist von der Papierbahn 2 abgefahren. Das Gewicht 10 befindet sich in seiner unteren Position. Der Vorhang 9 ist durch das Gewicht straff gespannt. FIG. 2 illustrates the rest position of the support beam 5. This has departed from the paper web 2. The weight 10 is in its lower position. The curtain 9 is taut by the weight.

Die Anlage gemäß der Figuren 3 und 4 ist genau so aufgebaut, wie jene gemäß Figur 3. Lediglich der Vorhang 9 ist etwas anders geführt. Er greift nämlich mit seinem einen Ende am Laufsteg 8 an. Er umschlingt eine Umlenkrolle 16. Dort befindet sich das im Sinne der Erfindung obere Ende des Vorhanges 9.The plant according to the Figures 3 and 4 is exactly the same as the one according to FIG. 3 , Only the curtain 9 is slightly different. He attacks namely with his one end on the catwalk 8. He wraps around a pulley 16. There is located in the context of the invention, the upper end of the curtain. 9

Auch hier ist der Vorhang zu jedem Zeitpunkt straff gespannt.Again, the curtain is taut at any time.

Bei beiden Anlagen, jener gemäß der Figuren 1 und 2 und jener gemäß der Figuren 3 und 4, ist zu jedem Zeitpunkt die Gefahrenzone abgesperrt, das ist jene Zone, die sich zwischen der linken Kante des Laufsteges 8 und der rechten unteren Kante des Tragbalkens 5 befindet.For both systems, that according to the FIGS. 1 and 2 and that according to the Figures 3 and 4 , the danger zone is shut off at any time, that is the zone which is located between the left edge of the catwalk 8 and the right lower edge of the support beam 5.

Anders ist es bei der konventionellen Anlage gemäß der Figuren 5 und 6.It is different in the conventional system according to the Figures 5 and 6 ,

Die Anlage ist im Grunde genau so aufgebaut, wie die zuvor beschriebenen, erfindungsgemäßen Anlagen. Man sieht jedoch, dass die Gefahrenzone durch ein Tuch 17 abgesperrt ist. Dieses schlägt im abgefahrenen Zustand des Tragbalkens 5, das heißt in der Ruheposition, Falten 18. Damit herrschen keine definierten Verhältnisse, so dass durchaus eine Quetsch- oder Verletzungsgefahr für die auf dem Laufsteg 8 befindliche Person und auch ein Verklemmen des faltigen Vorhanges besteht.The system is basically constructed exactly as the systems of the invention described above. It can be seen, however, that the danger zone is shut off by a cloth 17. This beats in the worn state of the support beam 5, that is, in the rest position, folds 18. Thus prevail no defined conditions, so that quite a crushing or injury to the person on the catwalk 8 person and also jamming of the wrinkled curtain exists.

Statt eines Laufsteges kann jegliche andere Art von Arbeitsbühne vorgesehen sein.Instead of a catwalk, any other type of work platform can be provided.
