Description

Die Erfindung betrifft eine Sicherheitswerkbank mit einer Frontscheibe, die mindestens eine zusätzliche Reinigungsposition aufweist.The invention relates to a safety workbench with a front window, which has at least one additional cleaning position.

Sicherheitswerkbänke erfüllen verschiedene Funktionen. Sie dienen im Allgemeinen dem Schutz des innerhalb der Werkbank zu ver- oder bearbeitenden Produkts, der Bedienperson und/oder der Umwelt.Safety cabinets fulfill various functions. They are generally used to protect the product to be processed or machined within the workbench, the operator and / or the environment.

Der Grundaufbau von Sicherheitswerkbänken umfasst einen von einem Gehäuse umschlossenen Innenraum und eine Arbeitsöffnung auf der Gehäusefrontseite, die von einer verstellbaren Frontscheibe verschließbar ist. Der Innenraum wird im Sinne der Erfindung auch als Arbeitsraum oder Arbeitsinnenraum bezeichnet. Solche Sicherheitswerkbänke sind in verschiedensten Ausführungsformen im Stand der Technik, wie zum Beispiel in der DE 44 41 784 A1 , der DE 102 17 903 C1 , der DE 297 23 636 und der DE 100 17 196 A1 beschrieben.The basic structure of safety workbenches comprises an inner space enclosed by a housing and a working opening on the front side of the housing, which can be closed by an adjustable windshield. The interior is referred to in the context of the invention as a working space or working space. Such safety workbenches are in various embodiments in the prior art, such as in the DE 44 41 784 A1 , of the DE 102 17 903 C1 , of the DE 297 23 636 and the DE 100 17 196 A1 described.

Die Frontscheibe spielt bei den verschiedenen Schutzfunktionen der Sicherheitswerkbank eine wesentliche Rolle. Sie verschließt den Arbeitsraum in der Arbeitsposition weitgehend gegen die Außenumgebung und verhindert das Austreten von Partikeln, dient der Bedienperson unter Anderem als Spritzschutz und verhindert umgekehrt auch das Eindringen von Partikeln aus dem äußeren Umfeld in den Arbeitsinnenraum.The windscreen plays an essential role in the various protective functions of the safety workbench. It closes the working space in the working position largely against the outside environment and prevents the escape of particles, serves the operator among other things as a splash guard and conversely also prevents the penetration of particles from the external environment into the working space.

Die Frontscheibe kann in einer Sicherheitswerkbank im Wesentlichen drei unterschiedliche Positionen einnehmen, nämlich die offene Endlage in der die Frontscheibe und damit auch die Arbeitsöffnung maximal geöffnet ist, die Arbeitsposition in der die Frontscheibe die Arbeitsöffnung im oberen Bereich teilweise verdeckt und die geschlossene Endlage, in der die Frontscheibe die Arbeitsöffnung im Wesentlichen vollständig abschließt.The windscreen can take in a safety workbench substantially three different positions, namely the open end position in which the windscreen and thus the work opening is maximally open, the working position in which the windscreen partially obscures the work opening in the upper part and the closed end position, in the the windscreen substantially completely closes the work opening.

Sicherheitswerkbänke in Laboratorien, insbesondere solche, die für mikrobiologische Arbeiten geeignet sind, müssen strengen Sicherheitsanforderungen genügen. Sie weisen zusätzlich Gebläse- und/oder Ablufteinrichtungen auf, die durch gerichtete Luftströmungen beispielsweise durch Partikel oder Aerolsole kontaminierte Luft abführen und so zusätzlich die Bedienperson schützen. Eine solche Sicherheitswerkbank ist beispielsweise in der DE 10 2004 032 454 A1 beschrieben. Um einen sicheren Betrieb zu gewährleisten, darf in einer solchen Sicherheitswerkbank die Frontscheibe nicht über längere Zeit weit geöffnet bleiben, da sich bei einem zu großen Öffnungsquerschnitt der Arbeitsöffnung die benötigten Luftströmungen nicht aufrecht erhalten lassen und so Produkt- und Personenschutz nicht sichergestellt sind.Safety workbenches in laboratories, especially those that are suitable for microbiological work, must meet stringent safety requirements. In addition, they have fan and / or exhaust air devices, which dissipate air which has been contaminated by directed air flows, for example by particles or aerosol oils, and thus additionally protect the operator. Such a safety workbench is for example in the DE 10 2004 032 454 A1 described. In order to ensure safe operation, the windscreen must not remain wide open for a long time in such a safety workbench, since the required air flows can not be maintained if the opening of the work opening is too large, thus preventing product and personal protection.

Zudem soll eine Bedienperson durch die Frontscheibe der Sicherheitswerkbank den Arbeitsraum einsehen und die Vorgänge innerhalb des Arbeitsraumes beobachten können. Hierdurch ist eine optische Kontrolle des Arbeitsraums möglich.In addition, an operator should be able to see through the windscreen of the safety workbench the workspace and observe the processes within the workspace. As a result, an optical control of the workspace is possible.

Aus verschiedenen Gründen kann es notwendig sein, den kompletten Arbeitsraum einer Sicherheitswerkbank und damit insbesondere auch die Innenseite der Frontscheibe zu reinigen. Zum Einen kann hierdurch die jeweils erforderliche Reinheit des gesamten Arbeitsinnenraumes, beispielsweise auch durch Desinfektion, her- und sichergestellt werden. Zum anderen kann durch direkte Kontamination und Verschmutzung der Frontscheibe die Sicht und damit die optische Kontrolle der Vorgänge innerhalb des Arbeitsraumes behindert werden. Verschmutzungen müssen dementsprechend beseitigt werden.For various reasons, it may be necessary to clean the entire workspace of a safety cabinet and thus in particular the inside of the windscreen. On the one hand, the required purity of the entire working space, for example by disinfection, can be ensured and ensured. On the other hand, direct contamination and soiling of the windscreen can obstruct the view and thus the optical control of the processes within the working space. Soiling must be removed accordingly.

Bei den bekannten Sicherheitswerkbänken ist die Frontscheibe so gelagert, dass sie im Wesentlichen parallel zur Gehäusefrontseite hoch und herunter verschoben werden kann. Hier ist es nicht möglich, die komplette Innenseite der Frontscheibe zu reinigen. Der Bereich, der bei einer Reinigung gerade nicht erreicht werden kann, liegt zudem im normalen Sichtbereich von Bedienpersonen, so dass die optische Kontrolle behindert wird.In the known safety workbenches, the windshield is mounted so that it can be moved up and down substantially parallel to the housing front side. Here it is not possible to clean the entire inside of the windscreen. The area, which can not be reached when cleaning, is also in the normal field of view of operators, so that the optical control is obstructed.

Andere Frontscheiben des Stands der Technik weisen zusätzlich Scharniere oder andere Klappmechanismen auf. Hier kann die Frontscheibe nach oben geöffnet und auf ihrer Innenseite gereinigt werden. Bei diesem Vorgang ist die Arbeitsöffnung der Sicherheitswerkbank vollständig zur Umgebung geöffnet. Die Umgebung ist einer möglichen Kontamination ausgesetzt. Zudem ist die Bedienperson dem möglicherweise kontaminierten Arbeitsinnenraum ausgesetzt, da sie beim Reinigungsvorgang unweigerlich nahe an diesen herantreten muss. Besonders nachteilig ist, dass sie hierbei nahezu zwangsläufig unterhalb der zu reinigenden Frontscheibe zu stehen kommt.Other prior art windscreens additionally include hinges or other folding mechanisms. Here, the windscreen can be opened upwards and cleaned on its inside. During this process, the workbench of the safety cabinet is completely open to the environment. The environment is exposed to possible contamination. In addition, the operator is exposed to the potentially contaminated working space, as it inevitably has to approach them during the cleaning process. A particular disadvantage is that it almost inevitably comes to stand below the windscreen to be cleaned.

In dieser geöffneten Position sind die Sicherheitsfunktionen der Frontscheibe somit ausgeschaltet. Die kontaminierte Frontscheibe selbst stellt sogar ein zusätzliches Risiko dar.In this open position, the safety functions of the windscreen are thus switched off. The contaminated windscreen itself is even an additional risk.

Zusätzlich nachteilig an den Frontscheiben des Stands der Technik ist, dass die Reinigung nur von unterhalb der Öffnung der Scheibe erfolgen kann und somit die Bedienperson Gefahr läuft, beispielsweise durch herab fallenden Schmutz oder herab tropfende Reinigungsflüssigkeit selbst kontaminiert zu werden. Dies ist ein besonders gravierendes Sicherheitsrisiko, wenn sich für die Bedienperson bei der Reinigung eine Überkopf-Arbeitsposition ergibt.Another disadvantage of the windshields of the prior art is that the cleaning can be done only from below the opening of the disc and thus the operator is in danger of being contaminated by falling down dirt or dropping cleaning liquid itself. This is a particularly serious safety hazard if the operator is over-worried during cleaning.

Aufgabe der vorliegenden Erfindung ist daher die Bereitstellung einer Sicherheitswerkbank mit einer Frontscheibe, die die Nachteile des Stands der Technik überwindet und bei der die Frontscheibe leichter vollständig zu reinigen ist, ohne dabei den Arbeitsraum vollständig freizugeben. The object of the present invention is therefore to provide a safety workbench with a windshield which overcomes the disadvantages of the prior art and in which the windshield is easier to completely clean, without completely releasing the working space.

Die Lösung dieser Aufgabe gelingt mit der Sicherheitswerkbank gemäß Anspruch 1. Weitere Ausführungsformen sind in den Unteransprüchen wiedergegeben.The solution of this problem is achieved with the safety workbench according to claim 1. Further embodiments are given in the dependent claims.

Die Erfindung betrifft eine Sicherheitswerkbank mit einem von einem Gehäuse umschlossenen Arbeitsraum und einer Gehäusefrontseite, die eine Arbeitsöffnung aufweist, welche von einer verstellbaren Frontscheibe verschließbar ist, wobei erfindungsgemäß die Frontscheibe mindestens eine zusätzliche Reinigungsposition aufweist, in der sie mindestens teilweise unterhalb einer geschlossenen Endlage, bei der die Arbeitsöffnung vollständig abgedeckt ist, derart angeordnet ist, dass zwischen Scheibenoberkante und Gehäuse eine Reinigungsöffnung gebildet wird. In dieser speziellen Reinigungsposition der Frontscheibe entsteht also eine Eingriffsöffnung als Spalt zwischen der oberen Kante der Frontscheibe und dem darüber befindlichen Gehäuseabschnitt, der die Arbeitsöffnung nach oben begrenzt. Diese Öffnung wird im Sinne der Erfindung als Reinigungsöffnung bezeichnet. Durch diese Reinigungsöffnung kann eine Bedienperson von oben hinter die Frontscheibe greifen und Reinigungsarbeiten durchführen, sodass die Scheibe sowohl von oben als auch von unten (bei Stellung der Frontscheibe in Arbeitsposition) - und damit vollständig - gereinigt werden kann.The invention relates to a safety workbench with a work space enclosed by a housing and a housing front side which has a work opening which can be closed by an adjustable windshield, wherein according to the invention the windscreen has at least one additional cleaning position in which it is at least partially below a closed end position the work opening is completely covered, is arranged such that between the upper edge of the disc and the housing, a cleaning opening is formed. In this special cleaning position of the windshield so an engagement opening is formed as a gap between the upper edge of the windshield and the overlying housing portion which limits the work opening upwards. This opening is referred to as a cleaning opening in the context of the invention. Through this cleaning opening, an operator can grab from behind the front window and perform cleaning work, so that the disc both from above and from below (in position of the windscreen in working position) - and thus completely - can be cleaned.

Besonders vorteilhaft ist hierbei, dass sich während des Reinigungsvorganges bei der erfindungsgemäßen Sicherheitswerkbank keine Kontamination durch herabfallende Schmutzpartikel oder herabtropfende Reinigungsflüssigkeiten ergeben kann. Zusätzlich kann auch keine Überkopf-Arbeitssituation für die Bedienperson entstehen.It is particularly advantageous in this case that during the cleaning process in the safety workbench according to the invention no contamination can result from falling dirt particles or dripping cleaning liquids. In addition, no overhead work situation can arise for the operator.

Ein weiterer Vorteil ist, dass die Öffnung des Arbeitsraumes nur in dem Maße erfolgen muss, wie das Hineingreifen durch die Bedienperson dies erforderlich macht. Im Übrigen bleibt die Arbeitsöffnung durch die Frontscheibe abgedeckt, so dass auch während des Reinigungsvorgangs ihre Schutzfunktionen im Wesentlichen aufrechterhalten werden können. Insbesondere können vorteilhafterweise auch die notwendigen Luftströmungen im Arbeitsraum aufrecht erhalten werden. So gelingt es erfindungsgemäß auch während des Reinigungsvorgangs, den Personen-, Umwelt- und Produktschutz zu sichern und entsprechenden Sicherheitsanforderungen zu genügen.Another advantage is that the opening of the work space must be made only to the extent that the intervention of the operator makes this necessary. By the way, the work opening remains covered by the windscreen, so that even during the cleaning process their protective functions can be substantially maintained. In particular, advantageously, the necessary air flows in the working space can be maintained. Thus, according to the invention, it is also possible, during the cleaning process, to ensure the protection of persons, the environment and the product and to meet the corresponding safety requirements.

Um sicherzustellen, dass die Frontscheibe nicht zu weit abgesenkt wird und dadurch beispielsweise eine zu große Öffnung entsteht, die die Aufrechterhaltung der angesprochenen Schutzparameter nicht mehr erlaubt, können zweckmäßig Mittel vorgesehen werden, die eine zu starke Absenkung der Frontscheibe verhindern. Dies können mechanische oder sonstige Sperren sein, die ein Absenken über eine bestimmte Endposition hinaus verhindern. Zu diesem Zweck kann es sinnvoll sein, eine an sich bekannte Messeinrichtung vorzusehen, mit welcher die Scheibenposition bestimmt werden kann. Die Scheibe kann in üblicher Weise manuell oder automatisch über eine in die Sicherheitswerkbank integrierte Bedieneinheit in die jeweils gewünschte Position verfahren werden. Die Bedieneinheit kann dabei so programmiert sein, dass ein Verfahren über die Reinigungsposition hinaus nach unten nicht möglich ist. Zweckmäßig wird die Reinigungsposition derart gewählt, dass die freigegebene Reinigungsöffnung nicht größer ist als die zulässige Öffnungsgröße der Arbeitsöffnung in einer Arbeitsposition, in der von einer Bedienperson Arbeiten im Arbeitsinnenraum der Sicherheitswerkbank vorgenommen werden. In diesem Fall ist sichergestellt, dass die vorgeschriebenen Sicherheitsbedingungen weiter eingehalten werden.In order to ensure that the windscreen is not lowered too far and thus, for example, creates an excessively large opening, which no longer allows the maintenance of the mentioned protection parameters, means may be provided which prevent excessive lowering of the windshield. These may be mechanical or other barriers that prevent lowering beyond a certain end position. For this purpose, it may be useful to provide a known measuring device with which the disk position can be determined. The disk can be moved in the usual way manually or automatically via an integrated into the safety cabinet operating unit in the respective desired position. The operating unit can be programmed in such a way that a method beyond the cleaning position downwards is not possible. Suitably, the cleaning position is selected such that the released cleaning opening is not greater than the permissible opening size of the working opening in a working position in which to be made by an operator working in the working interior of the safety cabinet. In this case, it is ensured that the prescribed safety conditions are maintained.

Abgesehen von den Ausgestaltungen, die das Absenken der Frontscheibe in die Reinigungsposition ermöglichen, kann die erfindungsgemäße Sicherheitswerkbank analog den bislang bekannten Sicherheitswerkbänken ausgestaltet sein. Auch die Antriebsvorrichtungen für die Frontscheibe können grundsätzlich wie im Stand der Technik ausgebildet sein und müssen nur geringfügig modifiziert werden, um das Absenken über die Position hinaus, in der die Arbeitsöffnung vollständig geschlossen ist, zu erlauben. Zur beweglichen Lagerung der Frontscheibe können in üblicher Weise zum Beispiel entlang der seitlichen Scheibenkanten beidseitig Führungsschienen vorhanden sein, in denen die Scheibe auf und ab läuft. Diese Führungsschienen können zum einen nach unten offen sein, sodass die Frontscheibe, um in die Reinigungsposition zu gelangen, nach unten teilweise aus ihnen herausfährt. Dies hat den Vorteil, dass die Führungsschienen gegenüber herkömmlichen Sicherheitswerkbänken nicht verlängert werden müssen. Alternativ können die Führungsschienen verlängert werden, sodass die Frontscheibe beim Verfahren in die Reinigungsposition zumindest eine Strecke lang zusätzlich in ihnen geführt wird. Sind die Führungsschienen so lang, dass die unteren Scheibenseitenkanten auch in der Reinigungsposition noch in ihnen lagern, können die Führungsschienen an ihrem unteren Ende verschlossen werden, wobei die verschlossenen Enden als Stopper für die Scheibe dienen können.Apart from the embodiments that allow the lowering of the windscreen in the cleaning position, the safety workbench according to the invention can be configured analogously to the previously known safety workbenches. The drive devices for the windshield can basically be formed as in the prior art and need only be slightly modified in order to allow the lowering beyond the position in which the working opening is completely closed. For movable mounting of the windshield can be provided on both sides in a conventional manner, for example, along the side window edges guide rails in which the disc runs up and down. On the one hand, these guide rails can be open at the bottom, so that the front window partially moves downwards to reach the cleaning position. This has the advantage that the guide rails need not be extended compared to conventional safety workbenches. Alternatively, the guide rails can be extended so that the windscreen is additionally guided in the cleaning position at least a distance in the process. If the guide rails are so long that the lower disc side edges are still stored in the cleaning position, the guide rails be closed at its lower end, wherein the closed ends can serve as a stopper for the disc.

In einer weiteren Ausgestaltung der Erfindung kann die Frontscheibe zwei- oder mehrteilig ausgebildet sein. Der Einsatz der Frontscheibe ist hierdurch flexibler zu gestalten und kann an die jeweilige Arbeitssituation angepasst werden. Zweckmäßigerweise können in dieser Ausgestaltung die Teile der Frontscheibe unabhängig voneinander verstellt werden. Beispielsweise kann die Frontscheibe in einen oberen und einen unteren Teil getrennt sein. Diese Teile können auch teilweise oder vollständig überlappend angeordnet sein. In dieser erfindungsgemäßen Ausführungsform kann vorteilhafterweise auch nur der obere Teil der Frontscheibe in eine Reinigungsposition abgesenkt werden. Hierbei wird der obere Teil der Frontscheibe in eine Position unterhalb seiner geschlossenen Endlage verschoben, während der untere Teil der Frontscheibe in seiner Position der geschlossenen Endlage verbleibt. Hierbei wird der obere Teil zweckmäßig hinter den unteren Teil der Frontscheibe bewegt. Auf diese Weise kann das Gewicht der zu bewegenden Teile reduziert werden.In a further embodiment of the invention, the windscreen may be formed in two or more parts. The use of the windscreen is thereby made more flexible and can be adapted to the particular work situation. Conveniently, the parts of the windscreen can be adjusted independently of each other in this embodiment. For example, the windscreen can be separated into an upper and a lower part. These parts can also be arranged partially or completely overlapping. In this embodiment of the invention, advantageously, only the upper part of the windscreen can be lowered into a cleaning position. Here, the upper part of the windscreen is moved to a position below its closed end position, while the lower part of the windscreen remains in its position of the closed end position. Here, the upper part is suitably moved behind the lower part of the windscreen. In this way, the weight of the parts to be moved can be reduced.

Die Erfindung wird nachfolgend in beispielhafter Weise anhand von zwei Ausführungsvarianten in Verbindung mit der Zeichnung erläutert. Die Erfindung ist nicht auf diese Ausführungsformen beschränkt.

shows a safety cabinet according to the invention in perspective view with the windscreen in a cleaning position.

Figur 1 zeigt eine erfindungsgemäße Sicherheitswerkbank 1, die beispielsweise bei mikrobiologischen Arbeiten eingesetzt werden kann. Die Sicherheitswerkbank 1 weist ein Gehäuse 2 auf, welches einen Arbeitsinnenraum 3 umgibt. An der Gehäusefrontseite 4 ist eine verstellbare Frontscheibe 5 angeordnet. Die Frontscheibe 5 ist so in einem Rahmen 6 gelagert, dass sie in seitlichen Führungsschienen 13, 14 im Wesentlichen parallel zur Gehäusefrontseite 4 hoch und herunter verschoben werden kann. Durch Herunterschieben der Frontscheibe 5 kann die auf der Gehäusefrontseite 4 befindliche Arbeitsöffnung 7 verkleinert werden. Die Höhe der freigegebenen Arbeitsöffnung ergibt sich somit aus dem Spalt zwischen der Unterkante 8 der Frontscheibe 5 und der Arbeitsraum-Bodenplatte oder Arbeitsebene 9. In ihrer geschlossenen Endlage ist die Unterkante 8 der Frontscheibe 5 in gleicher Höhe mit der Arbeitsebene 9 angeordnet und verschließt die Arbeitsöffnung 7 vollständig. Zusätzlich weist die Sicherheitswerkbank 1 die üblicherweise aus dem Stand der Technik bekannten Komponenten wie Gebläse, Filter, Mess-, Auswerte-, Steuer- und Regeleinrichtungen, eine Bedieneinheit usw. auf. FIG. 1 shows a safety workbench 1 according to the invention, which can be used for example in microbiological work. The safety workbench 1 has a housing 2 which surrounds a working interior 3. At the front of the housing 4 an adjustable windscreen 5 is arranged. The windshield 5 is mounted in a frame 6 so that it can be moved in side guide rails 13, 14 substantially parallel to the housing front side 4 up and down. By pushing down the windscreen 5, the located on the front side 4 housing opening 7 can be reduced. The height of the released work opening thus results from the gap between the lower edge 8 of the windshield 5 and the working space base plate or work plane 9. In its closed end position, the lower edge 8 of the windscreen 5 is arranged at the same height with the working plane 9 and closes the work opening 7 completely. In addition, the safety cabinet 1 usually from the prior art known components such as fans, filters, measuring, evaluation, control and regulating devices, an operating unit, etc. on.

Die Figur 2 zeigt die Sicherheitswerkbank aus Figur 1, bei der die Frontscheibe 5 entsprechend der erfindungsgemäßen Ausgestaltung über die geschlossene Endlage hinaus in eine Reinigungsposition abgesenkt wurde. Hierdurch entsteht an der Oberseite der Frontscheibe 5 eine Reinigungsöffnung 10, die durch weiteres Herunterschieben vergrößert werden kann. Die Höhe der Reinigungsöffnung 10 ergibt sich somit aus dem Spalt zwischen der Oberkante 11 der Frontscheibe 5 und dem oberhalb der Arbeitsöffnung 7 befindlichen Gehäuseabschnitt. Die Frontscheibe 5 ragt in dieser Position unten aus ihrem Rahmen 6 und den Führungsschienen 13, 14 heraus.The FIG. 2 shows the safety workbench FIG. 1 in which the windshield 5 has been lowered according to the embodiment of the invention beyond the closed end position in a cleaning position. As a result, at the top of the front screen 5, a cleaning opening 10, which can be increased by further pushing down. The height of the cleaning opening 10 thus results from the gap between the upper edge 11 of the windshield 5 and located above the working opening 7 housing portion. The windscreen 5 protrudes in this position below from its frame 6 and the guide rails 13, 14 out.

Die Frontscheibe 5 besteht in der Regel aus Glas, beispielsweise einem geeigneten Verbundglas. Sie kann aber auch aus anderem geeigneten Material, beispielsweise aus Kunststoff, gefertigt sein. Die Frontscheibe 5 kann anstelle der Lagerung in einem Rahmen mit Führungsschienen alternativ oder zusätzlich durch andere bekannte Haltevorrichtungen gehalten sein, die ein Absenken in eine erfindungsgemäße Reinigungsposition ermöglichen.The windscreen 5 is usually made of glass, for example a suitable laminated glass. But it can also be made of other suitable material, such as plastic. The windscreen 5 may be held instead of the storage in a frame with guide rails alternatively or additionally by other known holding devices that allow lowering into a cleaning position according to the invention.

Die Lüftungsvorrichtungen, wie z.B. Gebläse, Umluft-, Abluft- und Filtereinrichtungen, entsprechen demjenigen, was für den sicheren Betrieb einer Sicherheitswerkbank gemäß den jeweiligen, auch gegebenenfalls gesetzlich vorgeschriebenen, Normen und Anforderungen erforderlich sind. Solche Einrichtungen sind beispielsweise in der DE 10 2004 032 454 A1 beschrieben.The ventilation devices, such as fans, recirculation, exhaust air and filter devices, correspond to what is required for the safe operation of a safety cabinet according to the respective standards and requirements, which may also be required by law. Such devices are for example in the DE 10 2004 032 454 A1 described.

Die Sicherheitswerkbank 1 kann zusätzlich eine integrierte Bedieneinheit für die Steuerung verschiedener Gerätefunktionen aufweisen. Dies hat den Vorteil, dass der Betrieb der Sicherheitswerkbank nicht nur komfortabler für die Bedienperson ist, sondern auch die verschiedenen Funktionen, wie zum Beispiel die Einstellung von Gebläse- und Ablufteinrichtungen und die Scheibenposition, besser kontrolliert werden können und der Betrieb damit sicherer ist.The safety cabinet 1 may additionally have an integrated operating unit for the control of various device functions. This has the advantage that the operation of the safety cabinet is not only more comfortable for the operator, but also the various functions, such as the setting of fan and exhaust units and the disc position, can be better controlled and the operation is safer.

Die Frontscheibe 5 kann manuell verstellt oder über die Bedieneinheit zum Steuern von Gerätefunktionen in die verschiedenen Positionen, also auch in die Reinigungsposition, verfahren werden. Die Frontscheibe 5 kann dabei in herkömmlicher Weise in jeder Lage von der oberen offenen Endlage bis hin zur Reinigungsposition mittels bekannter Arretierungen festgelegt werden.The windscreen 5 can be adjusted manually or via the operating unit for controlling device functions in the various positions, including in the cleaning position, proceed. The windscreen 5 can be determined in a conventional manner in any position from the upper open end position to the cleaning position by means of known detents.

In einer vorteilhaften Weiterbildung der Erfindung ist ein Verfahren der Frontscheibe 5 in die Reinigungsposition nur in einem speziell eingestellten Reinigungsmodus möglich. Dieser kann beispielsweise über einen speziellen Schalter in einer Bedieneinheit eingestellt werden. Dies hat den Vorteil, dass im normalen Arbeitsbetrieb oder Arbeitsmodus der Sicherheitswerkbank bei einem Verfahren der Frontscheibe nach unten nicht unbeabsichtigt die geschlossene Endlage überfahren werden kann, also nur ein gezieltes Anfahren der Reinigungsposition möglich ist. Hierdurch wird eine erhöhte Betriebssicherheit erreicht.In an advantageous embodiment of the invention, a method of the windscreen 5 in the cleaning position only in a specially set cleaning mode is possible. This can be set for example via a special switch in a control unit. This has the Advantage that in normal working mode or working mode of the safety cabinet in a process of the windscreen down not inadvertently the closed end position can be run over, so only a targeted approach to the cleaning position is possible. As a result, increased reliability is achieved.

Vorteilhafterweise kann die erfindungsgemäße Sicherheitswerkbank 1 auch mindestens eine zusätzliche Sicherheitsüberwachungseinrichtung, beispielsweise Sensoren zur Kontrolle der Abluftoder Umluftströmung oder der Lufteintrittsgeschwindigkeit, oder eine Messeinrichtung zur Messung der Position der Frontscheibe aufweisen. Hierdurch kann verhindert werden, dass die Sicherheitswerkbank unbemerkt in nicht einwandfreiem Zustand betrieben wird. Diese Überwachungsfunktionen laufen bevorzugt auch während der Reinigungsphasen der Frontscheibe weiter.Advantageously, the safety workbench 1 according to the invention can also have at least one additional safety monitoring device, for example sensors for checking the exhaust air or circulating air flow or the air inlet velocity, or a measuring device for measuring the position of the windscreen. This can prevent that the safety workbench is operated unnoticed in improper condition. These monitoring functions preferably continue during the cleaning phases of the windscreen.

Zweckmäßigerweise können zusätzlich mit der Sicherheitsüberwachungseinrichtung Sollwerte für die verschiedenen Funktionen festgelegt werden, bei deren Über- oder Unterschreiten ein optischer oder akustischer Alarm gegeben wird. Eine solche Alarmfunktion kann vorteilhafterweise auch für den Fall vorgesehen werden, dass ein Ausfail oder Defekt eines Bauteils der Sicherheitswerkbank durch die Überwachungseinrichtung festgestellt wird. Die erfindungsgemäße Sicherheitswerkbank kann hierdurch eine erhöhte Betriebsicherheit erreichen und sicherstellen.Expediently, setpoint values for the various functions can additionally be defined with the safety monitoring device, and if they are exceeded or fallen below an optical or acoustic alarm is given. Such an alarm function can advantageously also be provided in the event that a fail or defect of a component of the safety workbench is detected by the monitoring device.
