Description

Die Erfindung bezieht sich auf eine Sicherung-Positioniervorrichtung für die, von den Lagereinbaustücken von Walzgerüsten abgekuppelten, auf, ortsfest am Walzgerüst angeordnete Haltenippel aufsteckbaren Kuppelenden von Versorgungsschläuchen.The invention relates to a fuse positioning device for those uncoupled from the bearing chocks of roll stands clip-on holding nipples fixed on the roll stand Dome ends of supply hoses.

Vorrichtungen dieser Art dienen dazu, die Kuppelenden der, am Walzgerüst selbst geführten und befestigten Versorgungsschläuche, nachdem diese von den Anschlüssen an den Lagereinbaustücken der Walzen des Walzgerüstes abgekuppelt worden sind, so zu sichern, daß die Schläuche bei dem nachfolgenden Ausfahren der Walzen mit den Lagereinbaustücken zum Zwecke des Walzenwechsels die Verfahrbewegungen nicht behindern und auch nicht beschädigt werden.Devices of this type serve the dome ends of the, on Roll stand self-guided and attached supply hoses, after this from the connections to the bearing chocks of Rolls of the roll stand have been uncoupled so that the hoses during the subsequent extension of the rollers with the Bearing chocks for the purpose of changing the rollers do not hinder or be damaged.

Eine bekannte Sicherungsvorrichtung für diesen Zweck besteht aus einer Reihe von, den jeweiligen Kuppelenden der Versorgungsschläuche zugeordneten Haltenippeln, auf die die Kuppelenden aufsteckbar sind. Diese Haltenippel sind fest, meistens in Reihe auf einer Tragplatte angeordnet, die an geeigneter Stelle des Walzgerüstes befestigt ist. Die Vorrichtung hat den Nachteil, daß sich die für den Walzenwechsel notwendige Freigabemeldung nur auf die visuelle Überprüfung der Vorrichtung stützen kann, und es ist, wie der praktische Betrieb gezeigt hat, die Möglichkeit vorhanden, daß je nach Art des Walzgerüsten und der Anordnung der Bedienungs- und Hilfsarmaturen an den Gerüstständern von der Bedienungsperson übersehen werden kann, daß einer oder mehrere der aufzusteckenden Kuppelenden der Versorgungsschläuche nicht aufgesteckt werden.A known safety device for this purpose consists of a series of, the respective dome ends of the supply hoses assigned holding nipples on which the dome ends can be attached. These holding nipples are fixed, usually in a row on a support plate arranged, which is attached to a suitable location of the roll stand. The device has the disadvantage that it is for the roll change necessary release notification only on the visual inspection of the Device can support, and it is like the practical operation has shown the possibility that depending on the type of roll stand and the arrangement of the operating and auxiliary fittings on the Scaffolding stands can be overlooked by the operator that one or more of the dome ends of the supply hoses to be attached not to be plugged on.

Der Erfindung liegt die Aufgabe zugrunde diesen Nachteil zu beseitigen und eine Vorrichtung der gattungsgemäßen Art zu schaffen, die sicherstellt, daß die Freigabemeldung für den Walzenwechsel erst abgegeben wird, wenn alle aufzusteckenden Kuppelenden sich in der vorgesehenen Aufsteckposition befinden.The object of the invention is to eliminate this disadvantage and to provide a device of the generic type which ensures that the release message for the roll change is is given when all of the dome ends to be attached are in the intended plug-in position.

Diese Aufgabe wird dadurch gelöst, daß die Haltenippel jeweils auf, in einem Rahmen parallel zueinander geführten Schiebekeilen angeordnet sind, die, federbeaufschlagt in Keilausnehmungen einer gemeinsamen Schaltstange ein- und mittels je einer zugeordneten Zugstange aus diesen herausziehbar sind, wobei die Schaltstange, federbeaufschlagt, quer zur Schieberichtung der Schiebekeile gegen ein Schaltelement in Schaltposition bewegbar ist, wenn sämtliche Schiebekeile mit auf Ihre Haltenippel aufgesetzten Kuppelenden aus den zugeordneten Keilausnehmungen heraus bewegt worden sind.This object is achieved in that the holding nipples on arranged in a frame parallel sliding wedges are the, spring-loaded in wedge recesses of a common Switch rod on and by means of an associated pull rod can be pulled out of these, the switching rod, spring-loaded, transverse to the sliding direction of the sliding wedges against a switching element is movable in the switching position when all sliding wedges with dome ends attached to your holding nipples from the assigned Wedge recesses have been moved out.

Diese Ausbildung der Vorrichtung stellt ohne vorherige Sichtüberprüfung sicher, daß die Schaltstange des Schaltelements erst betätigen kann, wenn die Kuppelenden aller Versorgungsschläuche auf die zugehörigen Haltenippel aufgesetzt worden sind.This design of the device provides without prior visual inspection sure that the switching rod of the switching element is actuated first can if the dome ends of all supply hoses on the associated nipples have been placed.

Wie die Erfindung weiter vorsieht, kann jeder der Schiebekeile an der, den Keilausnehmungen abgewandten Seite mit einer, in einer Wand des Rahmens geführten Zugstange verbunden sein, die von einer, gegen die Wand und den Schiebekeil abgestützen Zylinderfeder umfaßt wird. Vorteilhafter Weise kann dabei eine, die Reihe der auf den Schiebekeilen befindlichen Haltenippel in der, in die Keilausnehmungen eingreifenden Position der Schiebekeile abdeckende, ortsfest mit dem Rahmen verbundene Kulissenscheibe mit, die Haltenippel für das Aufstecken der Kuppelenden der Versorgungsschläuche in der, aus den Keilausnehmungen herausgezogenen Position freigebenden Ausnehmungen versehen sein.As the invention further provides, each of the sliding wedges can the side facing away from the wedge recesses with one in a wall of the frame guided drawbar connected by one, against the wall and the sliding wedge supported cylinder spring is included. Advantageously, one can, the row on the sliding wedges retaining nipple located in the, in the wedge recesses engaging position of the sliding wedges covering, stationary with connected to the frame backdrop, the holding nipple for Attach the dome ends of the supply hoses in the, from the Wedge recesses withdrawn position releasing recesses be provided.

Das Schaltelement wird zweckmäßig als, durch die Schaltstange beeinflußbarer Näherungsschalter ausgebildet.The switching element is expediently influenced by the switching rod Proximity switch designed.

Diese Ausbildungsform bringt den weiteren Vorteil mit sich, daß die Haltenippel für das Aufstecken der Kupplungsenden der Versorgungsschläuche nur zugänglich sind, wenn sie durch Herausziehen der Schiebekeile aus den Keilausnehmungen durch Betätigung der Zugstange, aus der, bisher durch die Kulissenscheibe abgedeckten Position in die Freigabeposition unterhalb der Ausnehmungen der Kulissenscheibe gebracht worden sind. Die Schiebekeile sind bei, auf den Haltenippel aufgestecktem Kuppelende auch positionsgesichert, da die Haltenippel in diesem Falle nicht mehr in die abgedeckte Position unterhalb der Kulissenscheibe bewegbar sind.This form of training has the further advantage that the Holding nipple for attaching the coupling ends of the supply hoses are only accessible if they are pulled out Sliding wedges from the wedge recesses by actuating the pull rod, from the position previously covered by the link plate in the release position below the recesses in the link plate have been brought. The sliding wedges are on the Holding nipple attached dome end also secured position, because in this case, the holding nipples no longer in the covered position are movable below the link plate.

Wie aus Fig. 1 zu ersehen sind die im Walzgerüst 1 geführten Lagereinbaustücke 2 und 3 der Walzen 4 und 5 jeweils mit einer Anschlußplatte 6 bzw. 7 versehen, die die Anschlußnippel für die Kuppelenden der am Walzgerüst 1 befestigten Versorgungsschläuche 8a, 8b, 8c, 8d bzw. 9a, 9b, 9c, 9d aufweist. Die Versorgungsschläuche sind hier in der Anschlußposition in unterbrochenen Linien angedeutet. Wenn die Versorgungsschläuche mit ihren Kuppelenden von den Anschlußnippeln der Anschlußplatte 6 bzw. der Anschlußplatte 7 gelöst worden sind, werden sie, wie in vollen Linien dargestellt mit Ihren Kuppelenden auf die Haltenippel 10a, 10b, 10c, 10d bzw. 11a, 11b, 11c, 11d der hier mit SV1 bzw. SV2 bezeichneten Sicherungvorrichtung aufgesetzt.As can be seen from FIG. 1, the bearing chocks guided in the roll stand 1 2 and 3 of the rollers 4 and 5 each with a connecting plate 6 or 7 provided that the connection nipple for the dome ends the supply hoses 8a, 8b, 8c attached to the roll stand 1, 8d or 9a, 9b, 9c, 9d. The supply hoses are here indicated in broken lines in the connection position. If the supply hoses with their dome ends from the connection nipples the connection plate 6 or the connection plate 7 has been released are, as shown in full lines with your dome ends to the holding nipples 10a, 10b, 10c, 10d or 11a, 11b, 11c, 11d of the securing device designated here as SV1 or SV2 put on.

Diese, in Fig. 2 wiedergegebene Sicherungvorrichtung besteht aus einem Rahmen 15, in dem die Schiebekeile SK1, SK2, SK3 und SK4 in Richtung des eingezeichneten Doppelpfeils S verschiebbar geführt sind. Auf den Schiebekeilen SK1, SK2, SK3, SK4 sind die Haltenippel HN1, HN2, HN3, HN4 angeordnet. Die Schiebekeile greifen in der für die Schiebekeile SK1, SK3 und SK4 dargestellten Position in Keilausnehmungen KA1, KA3, KA4 einer, ebenfalls in dem Rahmen 15 quer zur Verschieberichtung der Schiebekeile verschiebbar geführten Schaltstange 16 ein und halten diese in der dargestellten Position, die unter dem Druck der Feder 17 steht, fest. Die Schiebekeile SK1 - SK4 sind an der, dem Keilansatz abgewandten Seite mit einer Zugstange 18 verbunden, die ebenfalls in dem Rahmen 17 geführt ist, sie wird von einer, gegen die Rückseite des Schiebekeils und den Rahmen 15 abgestützen Zylinderfeder 19 umfaßt. Auf dem Rahmen 15, über den Schiebekeilen SK1 - SK4 befindet sich eine Kulissenscheibe 20 mit längsschlitzförmigen Ausnehmungen 21 für die Haltenippel HN1 - HN4. Auf diese Kulissenscheibe 20 ist ein Winkelprofil 22 aufgesetzt, dessen, parallel zur Kulissenscheibe 20 liegender Schenkel die Haltenippel HN1 - HN4 abdeckt, wenn sich der zugehörige Schiebekeil SK1 - SK4 in seiner, in die entsprechende Keilausnehmung KA1 - KA4 eingreifenden Position befindet. Die Kuppelenden der Versorgungsschläuche können in dieser Position nicht auf die Haltenippel aufgesetzt werden. Dies ist erst möglich, wenn sich der Schiebekeil, hier Schiebekeil SK2 in der, aus der entsprechenden Keilausnehmung herausgezogenen Position befindet. Ist das Kuppelende dann auf den Haltenippel aufgesetzt dann wirkt dieses, vgl. wieder den Schiebekeil SK2 wie ein Anschlag gegen die Kante 22a des Abdeckschenkels des Winkelprofils 22. This securing device shown in FIG. 2 consists of a frame 15 in which the sliding wedges SK1, SK2, SK3 and SK4 in Direction of the double arrow S shown slidably guided are. The holding nipples are on the sliding wedges SK1, SK2, SK3, SK4 HN1, HN2, HN3, HN4 arranged. The sliding wedges grip in the for the sliding wedges SK1, SK3 and SK4 shown position in wedge recesses KA1, KA3, KA4 one, also transversely in the frame 15 for the sliding direction of the sliding wedges Switch rod 16 and hold it in the position shown, which is under the pressure of the spring 17, fixed. The sliding wedges SK1 - SK4 are on the side facing away from the wedge with a pull rod 18 connected, which is also guided in the frame 17, it is by one, against the back of the sliding wedge and the frame 15 supported cylinder spring 19 includes. On the frame 15, over the Sliding wedges SK1 - SK4 there is a link plate 20 with longitudinal slot-shaped recesses 21 for the holding nipples HN1-HN4. An angular profile 22 is placed on this link plate 20, whose, parallel to the link plate 20 leg Holding nipple HN1 - HN4 covers when the associated sliding wedge SK1 - SK4 in its corresponding wedge recess KA1 - KA4 engaging position. The dome ends of the supply hoses cannot hold the nipple in this position be put on. This is only possible when the sliding wedge, here sliding wedge SK2 in, from the corresponding wedge recess pulled position. Is the end of the dome on the Then the nipple is in place, cf. the sliding wedge again SK2 like a stop against the edge 22a of the cover leg of the angle profile 22.

Wie ersichtlich wird die Schaltstange 16 solange in der dargestellten Position festgehalten, als sich noch mindestens ein Schiebekeil in der entsprechenden Keilausnehmung befindet. Sind alle Kuppelenden der entsprechenden Versorgungsleitungen auf die zugeordneten Haltenippel HN1 - HN4 der Schiebekeile SK1 - SK4 aufgesetzt, was, wie erläutert nur möglich ist, wenn die Schiebekeile außer Eingriff mit ihren zugehörigen Keilausnehmungen gebracht worden sind, dann kann sich die Schaltstange 16 aufgrund ihres Eigengewichtes, unterstützt durch die Feder 17 nach unten bewegen, womit der, ebenfalls in dem Rahmen 15 angeordnete Näherungsschalter 23, der das Freigabesignal bewirkt in Einschaltstellung gebracht wird.As can be seen, the shift rod 16 is shown in FIG Position held when there is still at least one sliding wedge is located in the corresponding wedge recess. Are all dome ends the corresponding supply lines to the assigned holding nipples HN1 - HN4 of the sliding wedges SK1 - SK4 put on what, how explained is only possible if the sliding wedges are out of engagement with their associated wedge recesses have been brought, then can the shift rod 16 is supported due to its own weight move down by the spring 17, whereby the, also in the Frame 15 arranged proximity switch 23, which the release signal is brought into the on position.
