- the present invention further relates to a clamping ring with the clamping ring locking device.
- clamping rings have a U-shaped or trapezoidal cross-sectional profile, in which a flat or rounded center piece connects an upper and a lower clamping ring leg. At least one of the two clamping ring legs is designed to run obliquely, often both clamping ring legs are also designed to run obliquely, the distance between the two clamping ring legs increasing inward towards the center of the clamping ring.
- a collar-shaped flange edge angled upwards and / or downwards can adjoin the upper and / or lower clamping ring legs.
- the clamping ring locking device bridges the two ends of the clamping ring, with the clamping ring-side swivel bearing base of the tensioning lever being welded onto one end of the clamping ring and the clamping ring-side swiveling bearing base of the tension bracket being firmly welded to the other end of the clamping ring.
- the clamping lever When the clamping lever is closed, the closed clamping ring has its smallest diameter, and when the clamping lever is opened, the opened clamping ring has its largest diameter.
- the largest diameter of the open clamping ring is required when putting on and removing the clamping ring from the lid flange edge and barrel body flange edge; for this, the clamping lever must be held in the fully opened position by hand.
- the smallest diameter of the closed clamping ring with the clamping lever folded in is required for axially clamping and pressing the drum lid with the drum lid seal onto the drum body mouth or the drum body edge.
- Tension rings with tension ring locking device for releasably securing a barrel lid on a lidded barrel are known in a wide variety of embodiments, such. B. from the publication DE 20 2013 000 452 U1 (Berger ).
- the clamping lever In the case of the clamping ring described therein, the clamping lever is fixed in the locking position by structural means in order to prevent the clamping lever or the clamping ring lock from opening accidentally or unintentionally.
- the clamping lever is closed in the closed position, there are many other proposed solutions in the known prior art.
- the present invention is aimed at a different set of problems.
- the clamping ring locking device with its two swivel bearing bases must be welded onto the two ends of the clamping ring. Since the clamping lever is only connected to the tension bracket by means of a pivot bolt, and the tension lever and tension bracket are also pivotably mounted on the outside by means of pivot bearings on the two pivot bearing bases, this prefabricated component unit is a comparatively unstable affair that is difficult to handle.
- the tensioning lever of the tensioning ring when opening a lidded barrel, the tensioning lever of the tensioning ring must be brought into a wide open position and held manually in order to be able to lift the opened tensioning ring from the barrel lid or lidded barrel.
- the tensioning lever of the tensioning ring When closing the lidded barrel, the tensioning lever of the tensioning ring must in turn be held in the wide open position with the largest diameter and only then can the opened tensioning ring be placed over the edge of the attached barrel lid and the lidded barrel edge and firmly closed.
- the tensioning lever and / or the tension bracket are provided with a special locking device which fixes the tensioning lever in a wide open position with an opening angle of greater than 90 °.
- the clamping ring locking device By fixing the clamping ring locking device in the wide open clamping lever positioning by means of the locking device designed as a snap-locking device, the clamping ring locking device can be handled much better during further processing.
- the clamping ring locking device which consists of four there is individual connected components pivotably connected via pivot bearings, now no longer a labile chain of components, but can be used in a defined rigid positioning in a storage magazine and then z. B. be fed to an automatic welding machine for welding the swivel bearing base with the clamping ring blank.
- the fully welded clamping ring with fixed clamping ring locking device in wide open clamping lever position can be transported by an automatic gripping and conveying device to a lidded barrel closing machine, where the widely spread tensioning ring is automatically placed on a lidded barrel with barrel lid and is closed.
- the locking device is designed as a snap-lock device with a snap element and a locking element, the snap element being arranged either on the tension bracket or on the clamping lever and the locking device Element is arranged correspondingly opposite on the clamping lever or on the tension bracket.
- the mutual fixation of the clamping lever and the tension bracket causes a wide spreading or wide opening of the clamping ring locking device, thereby creating the possibility of storing and transporting this component group in a defined stable arrangement and handling a clamping ring provided with the clamping ring locking device according to the invention generally to simplify and facilitate.
- the tension bracket has two parallel, opposite outer flanks, each of which is provided on its inner side with at least one protruding projection directed towards the opposite outer flank, which when the tensioning lever is positioned wide open in a corresponding manner engages in a matching recessed depression or recess in both outer sides of the side walls of the clamping lever.
- the two parallel, opposite outer flanks of the tension yoke hang together via a common center piece and are designed as a one-piece component. This results in a higher stability of the entire clamping ring locking device.
- the snap-locking device arranged between the tension bracket and the clamping lever is designed in such a way that when the clamping lever is positioned wide open, the snap element engages the locking element, the clamping lever having an opening angle of greater than 160 ° is fixed against the tension bracket.
- the tension bracket is designed to be extended on both sides by a short distance beyond the pivot bearing C common to the clamping lever, and these extensions each have an indentation on the outside and, accordingly, an inwardly pointing projection (locking cam) on the inside, a recess is provided in the side walls of the tensioning lever on both sides at a corresponding point, in which the projection can be snapped and latched in place when the tensioning lever is positioned wide open opposite (vis-a-vis).
- the clamping lever When considering a clamping ring with a closed clamping ring lock, the clamping lever rests on the clamping ring and the opening angle is zero. When the clamping ring lock is open, the clamping lever generally protrudes at right angles from the clamping ring, i. H. the opening angle is about 90 degrees. The tension ring is no longer under tension, but must still be opened and held by hand to place it on the drum lid and to remove it from the edge of the lid. By fixing the clamping ring locking device in a wide open position with an opening angle of the clamping lever of greater than 160 °, the clamping ring can easily be removed from the edge of the barrel or from the edge of the lid without the clamping lever having to be constantly held by hand. Likewise, it is now possible to place clamping rings with a fixation of the clamping ring closure device in fully open position and with the largest possible diameter in automatic lidded barrel closing systems fully automatically on barrel lids of lidded barrels and to close them.
- the clamping lever is on its side opposite the pivot bearing C - at the same distance as the inwardly pointing projections (locking cams) on the extension of the tension bracket from the pivot bearing C - equipped on both sides with corresponding depressions in its side walls in such a way that the Projections on the extension of the tension bracket with the fully closed positioning of the tensioning lever are designed to be snapped and latched into the corresponding depressions in the side walls of the tensioning lever as a locking device for the tensioning lever.

Description
Die vorliegende Erfindung betrifft eine Spannring-Verschlusseinrichtung für einen Spannring mit einem Spannhebel und einem ein- oder zweiteiligen Zugbügel, die beide jeweils mittels Schwenklager verschwenkbar auf einem spannringseitigen Schwenklagersockel befestigt sind, wobei der Zugbügel und der Spannhebel mittels eines weiteren gemeinsamen Schwenklagers verschwenkbar miteinander verbunden sind. Die vorliegende Erfindung betrifft weiterhin einen Spannring mit der Spannring-Verschlusseinrichtung.The present invention relates to a clamping ring locking device for a clamping ring with a clamping lever and a one- or two-part tension bracket, both of which are pivotably attached to a pivot bearing base on the clamping ring side by means of pivot bearings, the tension bracket and the tension lever being pivotably connected to one another by means of a further common pivot bearing . The present invention further relates to a clamping ring with the clamping ring locking device.
Spannringe weisen in aller Regel ein U-förmiges bzw. trapezförmiges Querschnittsprofil auf, bei dem ein flaches bzw. gerundetes Mittelstück einen oberen und einen unteren Spannringschenkel verbindet. Wenigstens einer der beiden Spannringschenkel ist schräg verlaufend ausgebildet, oftmals sind auch beide Spannringschenkel schräg verlaufend ausgebildet, wobei der Abstand der beiden Spannringschenkel nach innen zum Mittelpunkt des Spannringes hin zunimmt. Bei besonderen Ausführungsformen von Spannringen kann sich an den oberen oder/und unteren Spannringschenkel ein nach oben oder/und unten abgewinkelter kragenförmiger Flanschrand anschließen.As a rule, clamping rings have a U-shaped or trapezoidal cross-sectional profile, in which a flat or rounded center piece connects an upper and a lower clamping ring leg. At least one of the two clamping ring legs is designed to run obliquely, often both clamping ring legs are also designed to run obliquely, the distance between the two clamping ring legs increasing inward towards the center of the clamping ring. In the case of special embodiments of clamping rings, a collar-shaped flange edge angled upwards and / or downwards can adjoin the upper and / or lower clamping ring legs.
Die Spannring-Verschlusseinrichtung überbrückt die beiden Enden des Spannringes, wobei auf dem einen Ende des Spannringes der spannringseitige Schwenklagersockel des Spannhebels und auf dem anderen Ende des Spannringes der spannringseitige Schwenklagersockel des Zugbügels fest aufgeschweißt sind. Bei einem zugeklappten Spannhebel weist der geschlossene Spannring seinen kleinsten Durchmesser und bei einem aufgeklappten Spannhebel weist der geöffnete Spannring seinen größten Durchmesser auf. Der größte Durchmesser des geöffneten Spannringes ist erforderlich beim Aufsetzen und Abnehmen des Spannringes vom Deckelflanschrand und Fasskörperflanschrand, dazu muss der Spannhebel von Hand in voll aufgeklappter Position gehalten werden. Der kleinste Durchmesser des geschlossenen Spannringes mit angeklapptem Spannhebel ist zum axialen Verspannen und Aufeinanderpressen des aufgelegten Fassdeckels mit der Fassdeckeldichtung auf die Fasskörpermündung bzw. den Fasskörperrand erforderlich.The clamping ring locking device bridges the two ends of the clamping ring, with the clamping ring-side swivel bearing base of the tensioning lever being welded onto one end of the clamping ring and the clamping ring-side swiveling bearing base of the tension bracket being firmly welded to the other end of the clamping ring. When the clamping lever is closed, the closed clamping ring has its smallest diameter, and when the clamping lever is opened, the opened clamping ring has its largest diameter. The largest diameter of the open clamping ring is required when putting on and removing the clamping ring from the lid flange edge and barrel body flange edge; for this, the clamping lever must be held in the fully opened position by hand. The smallest diameter of the closed clamping ring with the clamping lever folded in is required for axially clamping and pressing the drum lid with the drum lid seal onto the drum body mouth or the drum body edge.
Spannringe mit Spannring-Verschlusseinrichtung zur lösbaren Befestigung eines Fassdeckels auf einem Deckelfass sind in den verschiedensten Ausführungsformen bekannt, so z. B. aus der Druckschrift
Die vorliegende Erfindung ist demgegenüber auf eine andere Problematik ausgerichtet. Bei der Herstellung von Spannringen muss einerseits die Spannring-Verschlusseinrichtung mit ihren beiden Schwenklagersockeln auf die beiden Enden des Spannringes aufgeschweißt werden. Da der Spannhebel nur mittels eines Schwenkbolzens mit dem Zugbügel verbunden ist, und Spannhebel und Zugbügel außenseitig ebenfalls mittels Schwenklager auf den beiden Schwenklagersockeln verschwenkbar gelagert sind, stellt diese vorgefertigte Bauteileinheit eine vergleichsweise labile Angelegenheit dar, die schwierig zu handhaben ist.In contrast, the present invention is aimed at a different set of problems. When producing clamping rings, on the one hand the clamping ring locking device with its two swivel bearing bases must be welded onto the two ends of the clamping ring. Since the clamping lever is only connected to the tension bracket by means of a pivot bolt, and the tension lever and tension bracket are also pivotably mounted on the outside by means of pivot bearings on the two pivot bearing bases, this prefabricated component unit is a comparatively unstable affair that is difficult to handle.
Andererseits muss beim Öffnen eines Deckelfasses der Spannhebel des Spannringes in eine weit geöffnete Position gebracht und manuell gehalten werden, um den geöffneten Spannring vom Fassdeckel bzw. Deckelfass abheben zu können. Beim Verschließen des Deckelfasses muss wiederum der Spannhebel des Spannringes in weit geöffneter Position bei größtem Durchmesser gehalten werden und erst dann kann der geöffnete Spannring über den Rand des aufgesetzten Fassdeckels und den Deckelfassrand gesetzt und fest geschlossen werden.On the other hand, when opening a lidded barrel, the tensioning lever of the tensioning ring must be brought into a wide open position and held manually in order to be able to lift the opened tensioning ring from the barrel lid or lidded barrel. When closing the lidded barrel, the tensioning lever of the tensioning ring must in turn be held in the wide open position with the largest diameter and only then can the opened tensioning ring be placed over the edge of the attached barrel lid and the lidded barrel edge and firmly closed.
Es ist Aufgabe der vorliegenden Erfindung, die Handhabung einer Spannring-Verschlusseinrichtung als vorgefertigte Bauteileinheit bei der Weiterverarbeitung als auch die Handhabung eines Spannringes mit aufgeschweißter Spannring-Verschlusseinrichtung beim Verschließen und Öffnen eines Deckelfasses mit Fassdeckel zu vereinfachen und eine weitergehende Automatisierung bei der Spannring-Fertigung sowie bei Deckelfass-Verschließmaschinen zu ermöglichen.It is the object of the present invention to simplify the handling of a clamping ring closure device as a prefabricated component unit during further processing as well as the handling of a clamping ring with a welded-on clamping ring closure device when closing and opening a lidded barrel with a barrel lid and further automation in the production of the clamping ring to enable lidded drum closing machines.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die beiden Bauteile Spannhebel und Zugbügel mit konstruktiven Mitteln versehen sind, die in funktioneller gegenseitig aufeinander abgestimmten Wirkungsweise zwischen den beiden Bauteilen als Schnapp-Rast-Einrichtung zur Fixierung der Spannring-Verschlusseinrichtung in weit geöffneter Spannhebel-Positionierung ausgebildet sind.This object is achieved according to the invention in that the two components clamping lever and tension bracket are provided with constructive means, which are functionally mutually coordinated between the two components as a snap-latch device for fixing the clamping ring locking device in the widely open clamping lever positioning are.
Als konstruktive Mittel sind dabei der Spannhebel oder/und der Zugbügel mit einer speziellen Arretierungs-Einrichtung versehen, die den Spannhebel in einer weit geöffneten Positionierung mit einem Öffnungswinkel von größer 90° fixiert.As structural means, the tensioning lever and / or the tension bracket are provided with a special locking device which fixes the tensioning lever in a wide open position with an opening angle of greater than 90 °.
Durch die Fixierung der Spannring-Verschlusseinrichtung in weit geöffneter Spannhebel-Positionierung mittels der als Schnapp-Rast-Einrichtung ausgebildeten Arretierungs-Einrichtung kann die Spannring-Verschlusseinrichtung bei der Weiterverarbeitung viel besser gehandhabt werden. Als vorgefertigte Bauteileinheit ist die Spannring-Verschlusseinrichtung, die aus vier einzelnen jeweils über Schwenklager verschwenkbar zusammenhängenden Bauteilen besteht, nun keine labile Bauteilekette mehr, sondern kann in definierter starrer Positionierung in ein Vorratsmagazin eingesetzt und dann z. B. einem Schweißautomaten zur Verschweißung der Schwenklagersockel mit dem Spannring-Rohling zugeführt werden. Nach Fertigstellung des Schweißvorganges kann der fertig geschweißte Spannring mit fixierter Spannring-Verschlusseinrichtung in weit geöffneter Spannhebel-Positionierung von einer automatischen Greif- und Förder-Einrichtung zu einer Deckelfass-Verschließmaschine transportiert werden, wo der weit aufgespreizte Spannring automatisch auf ein Deckelfass mit Fassdeckel aufgesetzt und verschlossen wird.By fixing the clamping ring locking device in the wide open clamping lever positioning by means of the locking device designed as a snap-locking device, the clamping ring locking device can be handled much better during further processing. As a prefabricated component unit, the clamping ring locking device, which consists of four there is individual connected components pivotably connected via pivot bearings, now no longer a labile chain of components, but can be used in a defined rigid positioning in a storage magazine and then z. B. be fed to an automatic welding machine for welding the swivel bearing base with the clamping ring blank. After completion of the welding process, the fully welded clamping ring with fixed clamping ring locking device in wide open clamping lever position can be transported by an automatic gripping and conveying device to a lidded barrel closing machine, where the widely spread tensioning ring is automatically placed on a lidded barrel with barrel lid and is closed.
In konstruktiver Ausgestaltung der Erfindung ist vorgesehen, dass die Arretierungs-Einrichtung als Schnapp-Rast-Einrichtung mit einem Schnapp-Element und einem Rast-Element ausgebildet ist, wobei das Schnapp-Element entweder an dem Zugbügel oder an dem Spannhebel angeordnet und das Rast-Element entsprechend gegenüberliegend an dem Spannhebel oder an dem Zugbügel angeordnet ist.In a structural embodiment of the invention it is provided that the locking device is designed as a snap-lock device with a snap element and a locking element, the snap element being arranged either on the tension bracket or on the clamping lever and the locking device Element is arranged correspondingly opposite on the clamping lever or on the tension bracket.
Durch die gegenseitige Fixierung von Spannhebel und Zugbügel wird eine weite Aufspreizung bzw. weite Öffnung der Spannring-Verschlusseinrichtung bewirkt und dadurch die Möglichkeit geschaffen, diese Bauteilgruppe in definierter stabiler Anordnung zu lagern, zu transportieren und die Handhabung eines mit der erfindungsgemäßen Spannring-Verschlusseinrichtung versehenen Spannringes allgemein zu vereinfachen und zu erleichtern.The mutual fixation of the clamping lever and the tension bracket causes a wide spreading or wide opening of the clamping ring locking device, thereby creating the possibility of storing and transporting this component group in a defined stable arrangement and handling a clamping ring provided with the clamping ring locking device according to the invention generally to simplify and facilitate.
In konkreter Ausgestaltung der Erfindung ist vorgesehen, dass die bzw. der Zugbügel zwei parallele, sich gegenüberliegende Außenflanken aufweist, die jeweils auf ihrer Innenseite mit wenigstens einem hervorstehenden, zur gegenüberliegenden Außenflanke gerichteten Vorsprung versehen sind, der bei weit geöffneter Positionierung des Spannhebels in entsprechender Weise in eine darauf abgestimmte rückspringende Vertiefung oder Aussparung in beiden Außenseiten der Seitenwandungen des Spannhebels einrastet.In a specific embodiment of the invention, it is provided that the tension bracket has two parallel, opposite outer flanks, each of which is provided on its inner side with at least one protruding projection directed towards the opposite outer flank, which when the tensioning lever is positioned wide open in a corresponding manner engages in a matching recessed depression or recess in both outer sides of the side walls of the clamping lever.
Insbesondere bei Spannringen mit größerem Durchmesser z. B. für 220 I Deckelfässer hängen die beiden parallelen, sich gegenüberliegenden Außenflanken der Zugbügel über ein gemeinsames Mittelstück zusammen und sind als einteiliges Bauteil ausgebildet. Dadurch wird eine höhere Stabilität der gesamten Spannring-Verschlusseinrichtung bewirkt.Especially with clamping rings with a larger diameter z. B. for 220 I lidded barrels, the two parallel, opposite outer flanks of the tension yoke hang together via a common center piece and are designed as a one-piece component. This results in a higher stability of the entire clamping ring locking device.
Bei einer weiteren Ausgestaltungsform der Spannring-Verschlusseinrichtung ist die zwischen Zugbügel und Spannhebel angeordnete Schnapp-Rast-Einrichtung derart ausgebildet, dass bei weit geöffneter Positionierung des Spannhebels das Schnapp-Element mit dem Rast-Element in Eingriff gelangt, wobei der Spannhebel mit einem Öffnungswinkel von größer 160° gegen den Zugbügel fixiert ist.In a further embodiment of the clamping ring locking device, the snap-locking device arranged between the tension bracket and the clamping lever is designed in such a way that when the clamping lever is positioned wide open, the snap element engages the locking element, the clamping lever having an opening angle of greater than 160 ° is fixed against the tension bracket.
Bei der bevorzugten erfindungsgemäßen Ausgestaltungsform der Spannring-Verschlusseinrichtung ist der Zugbügel beidseitig um ein kurzes Stück über das mit dem Spannhebel gemeinsame Schwenklager C hinaus verlängert ausgebildet und diese Verlängerungen weisen jeweils außenseitig eine Einformung und entsprechend innenseitig jeweils einen nach innen weisenden Vorsprung (Rastnocke) auf, wobei in den Seitenwandungen des Spannhebels beidseitig an entsprechender Stelle eine Vertiefung vorgesehen ist, in welche der Vorsprung bei weit geöffneter Positionierung des Spannhebels gegenüberliegend (vis a vis) fixierend einschnappbar und einrastbar ausgebildet ist.In the preferred embodiment of the clamping ring locking device according to the invention, the tension bracket is designed to be extended on both sides by a short distance beyond the pivot bearing C common to the clamping lever, and these extensions each have an indentation on the outside and, accordingly, an inwardly pointing projection (locking cam) on the inside, a recess is provided in the side walls of the tensioning lever on both sides at a corresponding point, in which the projection can be snapped and latched in place when the tensioning lever is positioned wide open opposite (vis-a-vis).
Bei Betrachtung eines Spannringes mit geschlossenem Spannring-Verschluss liegt der Spannhebel auf dem Spannring auf und der Öffnungswinkel ist gleich Null. Bei einem geöffneten Spannring-Verschluss steht der Spannhebel in aller Regel rechtwinkelig vom Spannring ab, d. h. der Öffnungswinkel beträgt etwa 90 Grad. Der Spannring steht nun nicht mehr unter Spannung, muss aber zum Aufsetzen auf den Fassdeckel sowie zum Abnehmen vom Deckelrand weiter von Hand geöffnet und gehalten werden. Durch die Fixierung der Spannring-Verschlusseinrichtung in weit geöffneter Positionierung mit einem Öffnungswinkel des Spannhebels von größer 160° kann der Spannring demgegenüber leicht vom Fassrand bzw. vom Deckelrand abgenommen werden, ohne dass dabei der Spannhebel ständig von Hand gehalten werden muss. Ebenso ist es nun möglich, Spannringe mit einer Fixierung der Spannring-Verschlusseinrichtung in vollständig geöffneter Positionierung und mit größtmöglichem Durchmesser in automatischen Deckelfass-Verschließanlagen vollautomatisch auf Fassdeckel von Deckelfässern aufzusetzen und zu verschließen.When considering a clamping ring with a closed clamping ring lock, the clamping lever rests on the clamping ring and the opening angle is zero. When the clamping ring lock is open, the clamping lever generally protrudes at right angles from the clamping ring, i. H. the opening angle is about 90 degrees. The tension ring is no longer under tension, but must still be opened and held by hand to place it on the drum lid and to remove it from the edge of the lid. By fixing the clamping ring locking device in a wide open position with an opening angle of the clamping lever of greater than 160 °, the clamping ring can easily be removed from the edge of the barrel or from the edge of the lid without the clamping lever having to be constantly held by hand. Likewise, it is now possible to place clamping rings with a fixation of the clamping ring closure device in fully open position and with the largest possible diameter in automatic lidded barrel closing systems fully automatically on barrel lids of lidded barrels and to close them.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist der Spannhebel auf seiner dem Schwenklager C entgegengesetzten Seite - im gleichen Abstand wie die nach innen weisenden Vorsprünge (Rastnocken) auf der Verlängerung des Zugbügels vom Schwenklager C - beidseitig mit entsprechenden Vertiefungen in seinen Seitenwandungen derart ausgestattet, dass die Vorsprünge auf der Verlängerung des Zugbügels bei vollständig geschlossener Positionierung des Spannhebels fixierend als Verschlusssicherung für den Spannhebel in die entsprechenden Vertiefungen in den Seitenwandungen des Spannhebels einschnappbar und einrastbar ausgebildet sind.In a further advantageous embodiment of the invention, the clamping lever is on its side opposite the pivot bearing C - at the same distance as the inwardly pointing projections (locking cams) on the extension of the tension bracket from the pivot bearing C - equipped on both sides with corresponding depressions in its side walls in such a way that the Projections on the extension of the tension bracket with the fully closed positioning of the tensioning lever are designed to be snapped and latched into the corresponding depressions in the side walls of the tensioning lever as a locking device for the tensioning lever.
Die Vertiefungen können auch als Langlöcher ausgebildet sein, wie die bereits vorhandenen Langlöcher im Spannhebel zur bekannten Verschlusssicherung mittels Plombierung durch eine Spannringöse.The depressions can also be designed as elongated holes, like the elongated holes already present in the tensioning lever for the known locking protection by means of a lead seal through a tension ring eyelet.

Derartige Spannringe werden z. B. zum Verschließen von Deckelfässern verwendet. Die Fassdeckel bestehen zumeist aus Kunststoff oder Metall, die Deckelfasskörper können ebenfalls aus Kunststoff, Metall oder ausgewickeltem Kraftpapier (Fiberdrum, Papptrommeln) bestehen. Die Spannringe bestehen aus verzinktem Stahlblechprofil und können Durchmessergrößen von 80 mm bis 2000 mm mit Materialstärken zwischen 0,5 mm bis 2,5 mm aufweisen. Standardmäßig liegt der Durchmesser zwischen 100 mm und 800 mm. In Querschnittsbetrachtung weisen die Spannringe ein aufgeweitetes U-förmiges bzw. trapezförmiges Profil mit oder ohne kragenförmigem Flanschrand auf. Die Spannringe können unterhalb der Spannring-Verschlusseinrichtung mit einer kurzen Überlappung, langen Überlappung oder ohne Überlappung ausgebildet sein.Such clamping rings are z. B. used to close lidded drums. The barrel lids are mostly made of plastic or metal, the barrel bodies can also be made of plastic, metal or wrapped kraft paper (fiber drum, cardboard drums). The clamping rings are made of a galvanized sheet steel profile and can have diameters from 80 mm to 2000 mm with material thicknesses between 0.5 mm and 2.5 mm. The standard diameter is between 100 mm and 800 mm. When viewed in cross-section, the clamping rings have a widened U-shaped or trapezoidal profile with or without a collar-shaped flange edge. The clamping rings can be formed below the clamping ring closure device with a short overlap, long overlap or without an overlap.

Der dargestellte Spannring-Verschluss 10 befindet sich in normal geöffneter Position, bei welcher der Spannhebel 14 üblicherweise in einer 90°-Position spannungsfrei verharrt und dabei etwa rechtwinkelig vom Spannring 12 absteht.The clamping
Gemäß der vorliegenden Erfindung ist der Spannring-Verschluss 10 im Nahbereich um das gemeinsame Schwenklager 26 von Spannhebel 14 und Zugbügel 16 mit einer Arretierungs-Einrichtung 28 versehen, die in vorliegender Ausführungsform als Schnapp-Rast-Einrichtung mit einem Rast-Element 42 und einem Schnapp-Element 44 zwischen dem Zugbügel 16 und dem Spannhebel 14 ausgebildet ist. Das Rast-Element 42 kann entweder an dem Zugbügel 16 oder dem Spannhebel 14 und das Schnapp-Element 44 entsprechend gegenüberliegend an dem Spannhebel 14 oder an dem Zugbügel 16 angeordnet sein. Im vorliegenden Fall dient das erwähnte Langloch 44 gleichzeitig als Schnapp-Element in geöffneter Position des Spannhebels 14. Als Rast-Element 42 sind in die Außenflanken des Zugbügels 16 von außen her zwei nebeneinander angeordnete runde Einformungen eingepresst, die auf der Innenseite der Zugbügelflanken als hervorstehende Rastnocken ausgebildet sind.According to the present invention, the clamping
Die konstruktive Besonderheit dieses Spannring-Verschlusses 10 besteht demnach darin, dass die Schnapp-Rast-Einrichtung in einer weit geöffneten Positionierung des Spannhebels 14 in einer aufeinander abgestimmten funktionellen Wirkungsweise zwischen Spannhebel 14 und Zugbügel 16 einrastet und den Spannhebel 14 - bezogen auf den spannhebelseitigen Schwenklagersockel 22 - in weit geöffneter Positionierung mit einem Öffnungswinkel von größer 90° fixiert. Dabei schnappen die Rastnocken-Rast-Elemente 42 in die Langloch-Schnapp-Elemente 44 ein.The special design feature of this
Diese weit geöffnete Positionierung des Spannring-Verschlusses 10 mit den in die (nicht sichtbaren) Langloch-Schnapp-Elemente 44 eingeschnappten Rastnocken-Rast-Elementen 42 ist in
Die Fixierung des Spannhebels 14 gegenüber dem Zugbügel 16 in weit geöffneter Positionierung macht aus der Verschlusseinrichtung 10 eine stabile Bauteileinheit, die bei der Spannringfertigung wesentlich leichter zu handhaben ist. Für eine serienmäßige Massenfertigung wird die vorgefertigte Verschlusseinrichtung nun als stabile Bauteileinheit in definierter aufgespreizter Form zur Lagerung und zum Transport in großen Stückzahlen in ein entsprechendes gitterartiges Haltegestell eingesetzt. Diese Haltegestelle werden dann zu einem Schweißautomaten transportiert und dort einem Vorratsmagazin zugeführt, so dass eine von einem Greifer des Schweißautomaten daraus einzeln entnommene aufgespreizte bzw. weit geöffnete Verschlusseinrichtung automatisch einem von anderer Seite zugeführten Spannring-Rohling aufgesetzt und automatisch mit diesem verschweißt wird. Die fertigen Spannringe mit aufgeschweißter Verschlusseinrichtung werden dann im weit aufgespreizten Zustand in ein anderes Rahmengestell eingelagert und zu einem vorgesehenem Einsatzort mit einer automatischen Deckelfass-Verschließmaschine transportiert. Dort wird maschinell jedem Deckelfasskörper ein Fassdeckel aufgelegt und ein fertiger weit geöffneter Spannring über den Rand des Fassdeckels aufgesetzt und zugespannt und das Deckelfass somit automatisch verschlossen.The fixing of the clamping
Bei schwereren Spannringen 12 für größere Deckelfässer sind die Spannring-Verschlusseinrichtungen 10 nicht mehr mit zwei separaten blechstreifenartigen Zugbügeln versehen, sondern mit einem einteiligen Zugbügel 16 ausgestattet, bei dem die zwei parallelen, sich gegenüberliegenden blechstreifenartigen Außenflanken 30, 32 über das gemeinsame Mittelstück 40 miteinander zusammenhängen. Die nachfolgenden Detailbeschreibungen der konstruktiven Ausgestaltung für einen einteiligen Zugbügel 16 sollen natürlich ebenso für zweiteilige Zugbügel gelten.In the case of heavier clamping rings 12 for larger lidded barrels, the clamping
Bei der bevorzugten Ausführungsform der Erfindung ist der Zugbügel 16 hinter dem spannringseitigen Schwenklager 26 (= Drehgelenk C) um ein kurzes Stück verlängert ausgebildet. Dieses kurze Stück einer Verlängerung 54 ist etwa so lang wie die Außenflanken 30, 32 des Zugbügels 16 hoch sind, d. h. im konkreten Fall weist die Verlängerung 54 eine Länge zwischen 8 mm und 36 mm, vorzugsweise 12 mm, auf. Die Länge der Verlängerung soll gerade so lang gestaltet sein, dass ein elastisches Verhalten der Schnapp-Rast-Einrichtung gewährleistet und ein plastisches Verbiegen der Verlängerung ausgeschlossen ist.In the preferred embodiment of the invention, the
Auf jeder Außenseite der Verlängerung 54 ist eine Einformung 50 eingeprägt, die auf der Innenseite der Verlängerung 54 als nach innen weisender Vorsprung 52 ausgebildet ist. Dieser innenseitige Vorsprung 52 ist im vorliegenden Fall als runde Rastnocke ausgebildet und stellt das Rast-Element zu einem auf der Außenseite des Spannhebels 14 angeordneten Schnapp-Element (Rundloch, Langloch) dar.
On each outer side of the
Grundsätzlich wird als Rast-Element ein Vorsprung (34, 52) bzw. eine um ca. 0,5 mm bis 1,5 mm vorspringende Rastnocke bzw. Erhebung und als Schnapp-Element eine entsprechende Vertiefung (44, 48, 56) wie ein Langloch, Rundloch, Nut, Rille, längliche Einsenkung bzw. Einformung angesehen, die in Zusammenwirkung eine Schnapp-Rast-Einrichtung ergeben.Basically, a projection (34, 52) or a locking cam or elevation protruding by approx. 0.5 mm to 1.5 mm is used as the locking element and a corresponding recess (44, 48, 56) such as a snap element Long hole, round hole, groove, groove, elongated depression or indentation viewed, which result in a snap-lock device in cooperation.
