The hood parts are brought in two different positions such as fixed and releasing positions, by rotating or linear displacement relative to one another. The hood parts are connected with each other in the fixed position, and the former part is removed from the latter part in the releasing position without using a tool. The bayonet joint component is formed as a groove and tongue assembly and a fixing element i.e. fixing screw (11).

Description

Die Erfindung betrifft eine Schutzhaube für ein rotierendes Objekt, insbesondere für eine Schleifscheibe einer Schleifmaschine, beispielsweise eines Doppelschleifers, mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a protective hood for a rotating object, in particular for a grinding wheel of a grinding machine, for example a double grinder, with the features of the preamble of claim 1.

Schleifinaschinen, insbesondere Doppelschleifer, müssen unter Berücksichtigung der Gefährdung von Bedienungspersonen bei einem Bruch der mit hoher Geschwindigkeit rotierenden Schleifscheibe mit einer den vorhandenen Unfallverhütungsvorschriften entsprechenden Schutzhaube für die Schleifscheibe ausgerüstet sein. Eine solche Schutzhaube umgibt die Schleifscheibe im Regelfall allseitig mit Ausnahme eines Ausschnittes an der Vorderseite der Schleifmaschine, um von dort Schleifgut an die Schleifscheibe heranführen zu können.Grinding machines, in particular double grinders, must be equipped with a protective cover for the grinding wheel corresponding to the existing accident prevention regulations taking into account the endangerment of operators in the event of a break of the grinding wheel rotating at high speed. Such a protective cover generally surrounds the grinding wheel on all sides, with the exception of a cutout on the front side of the grinding machine, in order to be able to introduce abrasive material therefrom to the grinding wheel.

Bei der bekannten Schutzhaube, von der die Erfindung ausgeht ( DE-A-29 38 411 ), befindet sich am Ausschnitt eine einstellbare Auflage für das Schleifgut. Außerdem befindet sich regelmäßig am Ausschnitt ein einstellbares Visier aus hochfestem, transparentem Material, durch das ein Benutzer die Bearbeitungsstelle des Schleifgutes zwar optisch betrachten kann, jedoch vor radial weggeschleuderten Partikeln geschützt ist.In the known protective hood, from which the invention proceeds ( DE-A-29 38 411 ), located at the neckline an adjustable support for the sanding. In addition, there is regularly at the neck of an adjustable visor made of high-strength, transparent material, through which a user can visually look at the processing point of the grinded, but is protected from radially thrown particles.

Die Befestigung der Schutzhaube an der Schleifmaschine erfolgt regelmäßig so, daß die dem Gehäuse der Schleifmaschine zugekehrte Seitenwand der Schutzhaube einfach mit mehreren auf dem Umfang verteilt angeordneten Befestigungsschrauben am Gehäuse der Schleifmaschine befestigt ist.The attachment of the guard on the grinding machine is done regularly so that the housing of the grinding machine facing side wall of the guard is simply mounted with a plurality of distributed around the circumference arranged fastening screws on the housing of the grinding machine.

Bei der bekannten Schutzhaube, von der die Erfindung ausgeht, ist diese Befestigung darüber hinaus so getroffen, daß die Verbindungsbauteile zur Aufnahme kinetischer Energie einer zu Bruch gegangenen Schleifscheibe bleibend plastisch verformbar sind.In the known protective hood, from which the invention proceeds, this attachment is also made such that the connecting components for absorbing kinetic energy of a broken grinding wheel are permanently plastically deformable.

Bekannt aus der Praxis ist auch eine Schutzhaube, die radial zweigeteilt ist. Hierbei sind die beiden Haubenteile an einer Überlappung durch eine Vielzahl von Verbindungsschrauben als Verbindungsbauteile verbunden.Known from practice is also a protective hood, which is divided into two radially. Here, the two hood parts are connected to an overlap by a plurality of connecting screws as connecting components.

In beiden Fällen ist die Demontage bzw. Öffnung der Schutzhaube zum Auswechseln des rotierenden Objekts, insbesondere der Schleifscheibe einer Schleifmaschine, langwierig, weil eine Vielzahl von Schraubverbindungen gelöst werden müssen. Das birgt im übrigen das zusätzliche Risiko, daß eine Bedienungsperson aus Bequemlichkeit nach dem Auswechseln der Schleifscheibe nicht mehr alle Verbindungsschrauben einschraubt, sondern nur einige der Verbindungsschrauben verwendet. Damit besteht dann ein erhebliches Sicherheitsrisiko beim Betrieb der Schleifmaschine.In both cases, the disassembly or opening of the protective cover for replacing the rotating object, in particular the grinding wheel of a grinding machine, tedious because a variety of screw must be solved. Incidentally, this involves the additional risk that an operator no longer screwed in all the connecting screws for convenience after replacing the grinding wheel, but only uses some of the connecting screws. There is then a considerable safety risk during operation of the grinding machine.

Entsprechende Schwierigkeiten gibt es bei Schutzhauben für rotierende Objekte aller Art, beispielsweise bei Auswuchtvorrichtungen, Schleudermaschinen, Zentrifugen o.dgl.. Ein besonderes Anwendungsfeld der vorliegenden Schutzhaube ist allerdings in der Tat eine Schleifmaschine, insbesondere in Form eines Doppelschleifers.Corresponding difficulties exist with protective hoods for rotating objects of all kinds, for example in balancing devices, centrifugal machines, centrifuges or the like. However, a particular field of application of the present protective cover is indeed a grinding machine, in particular in the form of a double-disc grinder.

Der Lehre der vorliegenden Erfindung liegt das Problem zugrunde, das Öffnen der Schutzhaube zu vereinfachen und den Betrieb mit geschlossener Schutzhaube dennoch sicherer zu machen.The teaching of the present invention is based on the problem of simplifying the opening of the guard and to make the operation with the guard closed still safer.

Das zuvor aufgezeigte Problem ist bei einer Schutzhaube mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The aforementioned problem is solved in a protective hood with the features of the preamble of claim 1 by the features of the characterizing part of claim 1.

Erfindungsgemäß wird ein Verdrehen oder lineares Verschieben der beiden Haubenteile relativ zueinander als solches genutzt, um zwischen einer Fixierposition und einer Löseposition zu unterscheiden. Dazu sind die Verbindungsbauteile als Bajonettverbindungsbauteile ausgeführt. Damit ist sichergestellt, daß stets alle Bajonettverbindungsbauteile in Fixierposition in Eingriff miteinander stehen. Das zuvor geschilderte, aus der Bequemlichkeit einer Bedienungsperson resultierende Gefährdungspotential fällt hier also systematisch weg. Gleichzeitig ist das Fixieren und Lösen der Haubenteile voneinander wesentlich einfacher als bei der aus dem Stand der Technik bekannten Schutzhaube.According to the invention, a twisting or linear displacement of the two hood parts relative to one another is used as such to distinguish between a fixing position and a release position. For this purpose, the connecting components are designed as bayonet connection components. This ensures that all bayonet connection components are always in the fixing position in engagement with each other. The above-described, resulting from the convenience of an operator hazard potential falls here so systematically. At the same time fixing and releasing the hood parts from each other is much easier than in the known from the prior art guard.

Bevorzugte Ausgestaltungen und Weiterbildungen der Lehre sind Gegenstand der Unteransprüche.Preferred embodiments and further developments of the teaching are the subject of the dependent claims.

Besonders zweckmäßig ist eine Ausführung der Bajonettverbindungsbauteile als Pilzkopfzapfen und zugeordnete Schlüssellochöffnungen. Aber auch abschnittsweise unterbrochene Nut-/Feder-Verbindungen können in zweckmäßiger Weise als Bajonettverbindungsbauteile genutzt werden.Particularly useful is an embodiment of the bayonet connection components as mushroom pin and associated keyhole openings. But also broken sections tongue and groove connections can be used in a useful manner as a bayonet connection components.

Besonders zweckmäßig ist es, wenn bei einem rotierenden Objekt auch die Haubenteile der Schutzhaube kreisscheibenförmig gestaltet sind und durch Verdrehen um ihre Mittelachse gegeneinander in die Fixierposition bzw. die Löseposition gebracht werden.It is particularly useful if in a rotating object and the hood parts of the guard are designed circular disc-shaped and are brought by rotation about their central axis against each other in the fixing position or the release position.

Besonders interessant ist eine Konstruktion, bei der vorgesehen ist, daß mindestens ein Verbindungsbauteil alternativ oder zusätzlich als werkzeugbetätigtes Fixierelement, insbesondere als Fixierschraube, ausgeführt ist. Mit einem einzigen Fixierelement, insbesondere einer einzigen Fixierschraube, kann man die Haubenteile relativ zueinander in der Fixierposition festlegen und damit die gewünschte Sicherung erreichen. Anstelle einer Fixierschraube kann ein werkzeugbetätigtes Fixierelement auch ein werkzeugbetätigter Exzenter oder eine werkzeugbetätigte, in die Fixierstellung vorgespannte Rastnase sein.Particularly interesting is a construction in which it is provided that at least one connecting component is alternatively or additionally designed as a tool-operated fixing element, in particular as a fixing screw. With a single fixing element, in particular a single fixing screw, you can set the hood parts relative to each other in the fixing position and thus achieve the desired backup. Instead of a fixing screw, a tool-operated fixing element can also be a tool-operated eccentric or a tool-actuated latching nose biased into the fixing position.

Anstelle eines von manchen Unfallverhütungsvorschriften vorgeschriebenen werkzeugbetätigten Fixierelementes, insbesondere in Form einer Fixierschraube, kann man bei geschickter Konstruktion auch ein manuell betätigbares Fixierelement vorsehen. Dabei kann es sich insbesondere um einen Exzenterklemmhebel oder um eine in die Fixierstellung vorgespannte, manuell aus der Fixierstellung heraus bewegbare Rastnase o.dgl. handeln. Auch damit läßt sich durch ein im Betrieb nicht verlierbares Bauteil die Fixierposition der beiden Haubenteile sicherstellen.Instead of a prescribed by some accident prevention regulations tool-operated fixing, in particular in the form of a fixing screw, one can also provide a manually operable fixing in skillful construction. This may in particular be an eccentric clamping lever or a biased into the fixing position, manually from the fixing position movable latching nose or the like. act. Even so, the fixation position of the two hood parts can be ensured by a non-loss in operation component.

Im folgenden wird nun die Erfindung anhand einer lediglich ein bevorzugtes Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Bei der Erläuterung der Zeichnung werden auch weitere Ausgestaltungen, Vorteile und Besonderheiten der erfindungsgemäßen Schutzhaube diskutiert. In der Zeichnung zeigt

In the following the invention will now be explained in more detail with reference to a drawing showing only a preferred embodiment. In the explanation of the drawing, further embodiments, advantages and features of the protective hood according to the invention are discussed. In the drawing shows

Dargestellt in Fig. 1 ist als Beispiel für den Einsatz einer erfindungsgemäßen Schutzhaube eine Schleifmaschine in Form eines Doppelschleifers mit einem Gehäuse 1, an dem sich unten ein Fuß 2 zum Anbringen auf einer Werkbank o.dgl. und oben ein Motorblock 3 mit dem darin befindlichen elektrischen Antriebsmotor befindet. Am Fuß 2 befindet sich ein Ein-/Aus-Schalter 4 für den Antriebsmotor. Rechts und links am Motorblock 3 befindet sich jeweils eine Schleifscheibe 5, die von einer Schutzhaube 6 mit Ausnahme eines Ausschnittes 7 zum Heranführen von Schleifgut geschützt ist.Shown in Fig. 1 is an example of the use of a protective hood according to the invention, a grinding machine in the form of a double grinder with a housing 1, at the bottom of a foot 2 for attachment to a workbench or the like. and above, an engine block 3 is located with the electric drive motor therein. At foot 2 is an on / off switch 4 for the drive motor. Right and left of the engine block 3 is in each case a grinding wheel 5, which is protected by a protective hood 6 with the exception of a cutout 7 for bringing abrasive material.

Am Ausschnitt 7 sieht man bei beiden Schleifscheiben 5 jeweils eine einstellbare Auflage 8 für das Schleifgut und oberhalb des Ausschnittes 7 jeweils ein einstellbares Visier 9, durch das eine Bedienungsperson geschützt ist, wenn sie die Arbeit mit dem Schleifgut an der Schleifscheibe 5 beobachtet.At the neck 7 one sees in both grinding wheels 5 each an adjustable support 8 for the abrasive and above the cutout 7 each have an adjustable visor 9, by which an operator is protected when she observes the work with the abrasive on the grinding wheel 5.

Wie bereits im allgemeinen Teil der Beschreibung ausgeführt worden ist, ist eine Schleifmaschine, insbesondere in Form eines Doppelschleifers, ein bevorzugtes Ausführungsbeispiel für den Einsatz einer erfindungsgemäßen Schutzhaube 6, nicht aber der einzige Anwendungsfall. Anwendung kann eine erfindungsgemäße Schutzhaube bei allen Arten von Vorrichtungen mit rotierenden Objekten finden, bei denen im Betrieb Gefahren für die Bedienungsperson bestehen, beispielsweise auch bei Auswuchtvorrichtungen, Schleudermaschinen, Zentrifugen o.dgl..As has already been stated in the general part of the description, a grinding machine, in particular in the form of a double grinder, is a preferred embodiment for the use of a protective hood 6 according to the invention, but not the only application. Application can find a protective hood according to the invention in all types of devices with rotating objects in which there are dangers for the operator during operation, for example, in balancing devices, centrifugal machines, centrifuges or the like.

Für eine derartige Schutzhaube 6, die aus einem ersten Haubenteil 6a und einem zweiten Haubenteil 6b besteht, das am ersten Haubenteil 6a befestigt ist, ist wesentlich, daß die dazu vorhandenen Verbindungsbauteile 10 im Betrieb nicht verlierbar sind. Bevorzugt ist es im übrigen, wenn das zweite Haubenteil 6b vom ersten Haubenteil 6a nur unter Verwendung eines Werkzeugs lösbar ist. Für die Lehre der Erfindung ist das aber nicht zwingend.For such a protective hood 6, which consists of a first hood part 6a and a second hood part 6b which is fastened to the first hood part 6a, it is essential that the connecting components 10 present for this purpose can not be lost during operation. Moreover, it is preferred if the second hood part 6b can be detached from the first hood part 6a only by using a tool. But this is not mandatory for the teaching of the invention.

Wesentlich ist nun, daß die beiden Haubenteile 6a, 6b durch Verdrehen oder lineares Verschieben relativ zueinander in zwei unterschiedliche Positionen bringbar sind, nämlich in eine Fixierposition, in der die Haubenteile 6a, 6b miteinander verbunden sind (Fig. 2), und in eine Löseposition, in der das zweite Haubenteil 6b ohne Verwendung eines Werkzeugs vom ersten Haubenteil 6a lösbar ist, und daß die Verbindungsbauteile 10 als Bajonettverbindungsbaueile 10 ausgeführt sind. Für die Erläuterungen der Vorteile dieser Konstruktion darf auf den allgemeinen Teil der Beschreibung verwiesen werden.It is essential that the two hood parts 6a, 6b can be brought into two different positions by twisting or linear displacement relative to one another, namely into a fixing position in which the hood parts 6a, 6b are connected to one another ( Fig. 2 ), and a release position in which the second hood part 6b is detachable from the first hood part 6a without using a tool, and that the connection parts 10 are made as bayonet connection parts 10. For the explanation of the advantages of this construction, please refer to the general part of the description.

Im dargestellten und bevorzugten Ausführungsbeispiel ist vorgesehen, daß die Bajonettverbindungsbauteile 10 als Pilzkopfzapfen 10a und zugeordnete Schlüssellochöffnungen 10b ausgeführt sind. Man sieht dies in Fig. 2 und 3 besonders deutlich. Durch eine Drehung des zweiten Haubenteils 6b gegenüber dem ersten Haubenteil 6a entgegen dem Uhrzeigersinn werden die beiden Haubenteile 6a, 6b in die Fixierposition gebracht, die in Fig. 2 dargestellt ist.In the illustrated and preferred embodiment, it is provided that the bayonet connection components 10 are designed as mushroom pin 10 a and associated keyhole openings 10 b. You can see this in Fig. 2 and 3 especially clear. By a rotation of the second hood part 6b relative to the first hood part 6a in the counterclockwise direction, the two hood parts 6a, 6b are brought into the fixing position, which in Fig. 2 is shown.

Bereits oben diskutiert worden ist eine andere Konstruktion für die Bajonettverbindungsbauteile 10, nämlich dergestalt, daß die Bajonettverbindungsbauteile 10 als abschnittsweise unterbrochene Nut-/Feder-Verbindungen ausgeführt sind. Auch weitere Varianten von Bajonettverbindungstechniken können eingesetzt werden.Already discussed above is another construction for the bayonet connection components 10, namely such that the bayonet connection components 10 are designed as partially interrupted groove / tongue connections. Other variants of bayonet connection techniques can be used.

Das in Fig. 2 und 3 dargestellte bevorzugte Ausführungsbeispiel zeigt ferner, daß mindestens ein Verbindungsbauteil 10 alternativ oder zusätzlich als werkzeugbetätigtes Fixierelement 11, insbesondere als Fixierschraube, ausgeführt ist. Genauer gesagt ist ein Pilzkopfzapfen oben rechts durch eine Kreuzschlitz-Fixierschraube als Fixierelement 11 ersetzt worden. Diese Fixierschraube wird mit einem Kreuzschlitz-Schraubendreher festgesetzt und dadurch ist das komplette zweite Haubenteil 6b gegenüber dem ersten Haubenteil 6a festgesetzt. Von selbst sind dabei allerdings alle Bajonettverbindungsbauteile 10 miteinander in Eingriff, so daß eine optimale Sicherung der Schutzhaube 6 realisiert ist. Werkzeugbetätigt können auch andere Fixierelemente arbeiten, z.B. ein Exzenter oder eine Rastung.This in Fig. 2 and 3 illustrated preferred embodiment also shows that at least one connecting member 10 is alternatively or additionally designed as a tool-operated fixing element 11, in particular as a fixing screw. More specifically, a mushroom peg has been replaced in the upper right by a Phillips screw as a fixing member 11. This fixing screw is fixed with a Phillips screwdriver and thereby the complete second hood part 6b is fixed relative to the first hood part 6a. By itself, however, all bayonet connection components 10 are engaged with each other, so that an optimal backup of the protective cover 6 is realized. Tool-operated, other fixing elements work, such as an eccentric or a detent.

Grundsätzlich ist die Lehre der Erfindung auch dann mit Vorteil anwendbar, wenn nicht ein werkzeugbetätigtes Fixierelement 11, sondern ein manuell betätigbares Fixierelement vorgesehen ist, insbesondere ein Exzenterklemmhebel oder eine in die Fixierstellung vorgespannte Rastnase o.dgl.. Auch damit wird eine komplette Verriegelung der beiden Haubenteile 6a, 6b miteinander erreicht.In principle, the teaching of the invention is also advantageously applicable, if not a tool-operated fixing element 11, but a manually operable Fixing element is provided, in particular a Exzenterklemmhebel or biased into the fixing position locking lug or the like .. Also, a complete locking of the two hood parts 6a, 6b is achieved with each other.

Angedeutet in Fig. 2 und gut zu erkennen rechts in Fig. 3 ist eine Besonderheit der hier dargestellten Konstruktion, die darin besteht, daß dem gleichzeitig als Bajonettverbindungsbauteil 10a ausgeführten Fixierelement 11 ein Blockierelement 12 zugeordnet ist, durch das eine Bewegung des zugeordneten Bajonettverbindungsbauteils 10b formschlüssig blockiert ist, wenn das Fixierelement 11 seine Fixierstellung einnimmt. Dieses Blockierelement 12 ist im dargestellten Ausführungsbeispiel einfach als kleiner, nach außen auftragender Steg am zweiten Haubenteil 6b ausgeführt. Ist die das Fixierelement 11 bildende Fixierschraube fest angezogen worden, so liegt sie hinter dem Blockierelement 12 und eine Drehung des zweiten Haubenteils 6b gegenüber dem ersten Haubenteil 6a im Uhrzeigersinn ist durch das Blockierelement 12 formschlüssig ausgeschlossen.Indicated in Fig. 2 and good to see right in Fig. 3 is a peculiarity of the construction shown here, which consists in that at the same time designed as a bayonet connection member 10a fixing element 11 is associated with a blocking element 12 by which a movement of the associated bayonet connection member 10b is positively locked, when the fixing member 11 assumes its fixing position. This blocking element 12 is in the illustrated embodiment simply designed as a small, outwardly applying web on the second hood part 6b. If the fixing screw 11 forming fixing screw has been tightened, it is behind the blocking element 12 and a rotation of the second hood part 6b relative to the first hood part 6a in the clockwise direction is positively excluded by the blocking element 12.

Fig. 2 und 3 zeigen weiter im Zusammenhang, daß die beiden Haubenteile 6a, 6b gemeinsam eine kreisscheibenförmige Schutzhaube 6 bilden, die in einer Mittelebene oder einer dazu parallelen Ebene in die beiden Haubenteile 6a, 6b geteilt ist. Im dargestellten Ausführungsbeispiel ist das erste Haubenteil 6a gewissermaßen kreisscheibenförmig-topfförmig ausgestaltet, während das zweite Haubenteil 6b als kreisscheibenförmiger, flacher Deckel ausgeführt ist. In der Mitte des ersten Haubenteils 6a sieht man im übrigen die Durchtrittsöffnung 13 für die Antriebswelle, auf der die Schleifscheibe 5 aufgespannt ist. Fig. 2 and 3 show further in context that the two hood parts 6a, 6b together form a circular disc-shaped protective hood 6, which is divided in a central plane or a plane parallel thereto in the two hood parts 6a, 6b. In the illustrated embodiment, the first hood part 6a is designed as it were circular disk-shaped cup-shaped, while the second hood part 6b is designed as a circular disc-shaped, flat lid.
