Abstract

In the opened state, the clamping ring (6) has no parts which connect its two end portions (6a, 6b) to one another, that is to say no clamping device consisting of a clamping lever and connecting lever. As a result, it is less expensive in manufacture than a clamping ring fitted with a clamping device. This is therefore very advantageous because the clamping rings are usually no longer used after the initial opening of a container, but thrown away. Serving for securing the ring in the closed state are a releasing mechanism (8), constructed as a lug, at one end portion (6b) of the ring and a corresponding opening (7) at the other end portion (6a), in the closed state the lug (8) being thrust through the opening (7) and secured in this position by a securing pin. For closing a clamping ring of this type, an inexpensive closing device can be used. <IMAGE>

Description

Ein Eimer ist ein Behälter mit einer zylindrischen oder leicht konische Wand und einem ebenen, kreisrunden Boden sowie einem abnehmbaren Deckel.A bucket is a container with a cylindrical or slightly conical wall and a flat, circular base and a removable lid.

Es ist üblich, derartige Eimer mit einem Eindrückdeckel zu verschliessen und den Mantelrand an der Einfüllöffnung zur Erhöhung der Stabilität, zur Erreichung eines luft- und flüssigkeitsdichten Verschlusses und zum Schutz gegen Beschädigung nach aussen umzurollen, also den Eimer mit einem Rollrand zu versehen. Zum Festhalten des eingesetzten Eindrückdeckels wird ein einen im wesentlichen V-förmigen Querschnitt aufweisender Spannring verwendet, dessen freie Enden durch einen aus einem Spannhebel und einem Verbindungshebel bestehenden Spannverschluss zusammengehalten werden. Wenn, wie das oft der Fall ist, derartige Spannringe nach dem ersten Öffnen des Eimers nicht mehr benützt sondern fortgeworfen werden, dann stellt sich das Problem, wie sich solche als Wegwerfartikel zu betrachtende Spannringe preiswerter als bisher herstellen lassen und wie sich allenfalls der Materialaufwand oder Materialverschleiss zu ihrer Herstellung vermindern lässt.It is customary to close such buckets with a press-in lid and to roll the edge of the jacket at the filling opening to increase stability, to achieve an air- and liquid-tight seal and to protect against damage to the outside, that is to say to provide the buckets with a rolled rim. A clamping ring having an essentially V-shaped cross section is used to hold the press-in cover used, the free ends of which are held together by a clamping lock consisting of a clamping lever and a connecting lever. If, as is often the case, such clamping rings are no longer used after the first opening of the bucket but are thrown away, then the problem arises as to how such clamping rings, which are to be regarded as disposable items, can be produced more cheaply than before and how the material expenditure or Material wear can be reduced to their manufacture.

Es wurde nun gefunden, dass ein Spannring, dessen freie Endabschnitte sich im geschlossenen Zustand überlappen, seine Funktion eben so gut erfüllt, wenn er so ausgebildet ist, dass die Ringenden im offenen Zustand des Rings nicht miteinander verbunden sind, wobei derjenige Endabschnitt, der im geschlossenen Zustand des Rings den anderen Endabschnitt überlappt, eine Öffnung aufzuweisen hat, während der andere Endabschnitt derart mit einer als Öse ausgebildeten Ausklinkung versehen sein muss, dass sich diese bei geschlossenem Zustand des Rings durch die vorgenannten Öffnungen hindurch stecken lässt. Es handelt sich also um einen Spannring ohne Spannverschluss. Die Erfindung betrifft daher auch eine ganz einfache Vorrichtung zum Schliessen derartiger Spannringe sowie eine etwas aufwendigere Schliessvorrichtung, die sich in einer Abfüll- und Verschliessstrasse ohne weiteres anordnen lässt.It has now been found that a clamping ring, the free end sections of which overlap in the closed state, fulfills its function just as well if it is designed in such a way that the ring ends are not connected to one another in the open state of the ring, the end section which in the closed state of the ring overlaps the other end section, has an opening, while the other end section must be provided with a notch designed as an eyelet, so that it can be inserted through the aforementioned openings when the ring is closed. It is a tension ring without a tension lock. The invention therefore also relates to a very simple device for closing such clamping rings and to a somewhat more complex closing device which can be easily arranged in a filling and sealing line.

Nachfolgend werden Ausführungsbeispiele der Erfindung anhand der beiliegenden Zeichnung beschrieben.Exemplary embodiments of the invention are described below with reference to the accompanying drawing.

In der Zeichnung zeigt

  • die Figur 1 einen Teil eines Vertikalschnittes durch einen Kesselrand mit lose aufgesetztem Dekkel, der mit einem noch offenen Spannring versehen ist,
  • die Figur 2 einen gleichartigen Schnitt jedoch nach dem Eindrücken des Deckels und dem Schliessen des Spannrings,
  • die Figur 3 einen Ausschnitt aus einem horizontalen Schnitt durch einen geöffneten Spannring,
  • die Figur 4 den gleichen Ausschnitt wie die Figur 3, aber bei geschlossenen Spannring,
  • die Figur 5 eine Draufsicht auf eine Schliessvorrichtung,
  • die Figur 6 die rechte Seite eines Vertikalschnitts durch eine andere Schliessvorrichtung und
  • die Figur 7 den mit VII bezeichneten Ausschnitt aus der Figur 6.
In the drawing shows
  • 1 shows a part of a vertical section through a kettle rim with a loosely attached lid, which is provided with a still open clamping ring,
  • 2 shows a similar section, however, after the cover has been pressed in and the clamping ring closed,
  • 3 shows a section of a horizontal section through an open clamping ring,
  • 4 shows the same section as FIG. 3, but with the clamping ring closed,
  • 5 shows a plan view of a locking device,
  • 6 shows the right side of a vertical section through another locking device and
  • 7 shows the section designated by VII from FIG. 6.

In den Figuren 1 und 2 ist der obere Rand einer mit 1 bezeichneten Kesselwandung dargestellt, der mit einer eingerollten Kante 2 der Breite B versehen ist.In Figures 1 and 2, the upper edge of a boiler wall designated 1 is shown, which is provided with a rolled edge 2 of width B.

In der Kesselöffnung sitzt der Eindrückdeckel 3. In der Figur 1 ist dieser Deckel lose ein- oder aufgelegt, während er in der Figur 2 vollständig in die Kesselöffnung eingedrückt ist, so dass diese verschlossen ist. Der Deckel 3 selber ist ebenfalls mit einem eingerollten Rand 4 versehen, wobei dieser Rand den Dichtungsring 5 aus elastischem Material festhält. Mit 6 ist der erfindungsgemässe Spannring bezeichnet, von welchem die Figuren 3 und 4 einen Horizontalschnitt darstellen. Es handelt sich also um einen offenen Ring mit V-förmigem Querschnitt. Die beiden freien Endabschnitte des Rings sind mit 6a und 6b bezeichnet. Der Endabschnitt 6a, der im geschlossenen Zustand des Rings den anderen Endabschnitt 6b überlappt oder überdeckt, weist eine Öffnung 7 auf, während der andere Endabschnitt 6b mit einer als Öse ausgebildeten Ausklinkung 8 versehen ist, wobei die Öffnung 7 und Öse 8 so bemessen sind, dass sich die Öse 8 bei geschlossenem Zustand des Rings 6, also dann wenn er, wie das in der Figur 2 dargestellt ist, satt am Deckel und am Bördelrand 2 des Eimers anliegt, durch die Öffnung 7 hindurchstekken lässt, wie das aus der Figur 4 ersichtlich ist. In diesem geschlossenen Zustand, der einen dichten Verschluss des Kessels gewährleistet, kann man durch die Öse 8 einen Sicherungsstift 9 hindurchstecken und so ein Öffnen des Rings 6 und damit natürlich auch ein Entfernen des Deckels 3 verhindern.The press-in cover 3 is seated in the boiler opening. In FIG. 1, this cover is loosely inserted or placed on, while in FIG. 2 it is fully pressed into the tank opening so that it is closed. The lid 3 itself is also provided with a rolled edge 4, this edge holding the sealing ring 5 made of elastic material. 6 is the tension ring according to the invention, of which FIGS. 3 and 4 represent a horizontal section. So it is an open ring with a V-shaped cross-section. The two free end sections of the ring are designated 6a and 6b. The end section 6a, which in the closed state of the ring overlaps or covers the other end section 6b, has an opening 7, while the other end section 6b is provided with a notch 8 designed as an eyelet, the opening 7 and eyelet 8 being dimensioned in such a way that that the eyelet 8 can be inserted through the opening 7 when the ring 6 is closed, i.e. when it, as shown in FIG. 2, fits snugly against the lid and the flanged edge 2 of the bucket, as in FIG. 4 can be seen. In this closed state, which ensures a tight closure of the boiler, a locking pin 9 can be inserted through the eyelet 8 and thus prevent the ring 6 from being opened and, of course, also from removing the cover 3.

Es ist nun besonders zweckmässig, wenn man die Öffnung 7 im Endabschnitt 6a so anordnet, dass der Abstand zwischen ihr und der benachbarten Endkante 6c 7T. B beträgt, und dem Ring gleichzeitig ein solche Form gibt, dass die Endkante 6c des Endabschnitts 6a an der Öse 8 ansteht. Das hat nämlich zur Folge, dass der Radius des offenen Ringes um grösser ist als der Radius des geschlossenen Rings, mit anderen Worten, dass der geöffnete Ring 6 derart lose auf dem Rand des Deckels 3 sitzt, dass er nicht abfällt und dass seine untere Kante 6d etwa auf der Mitte des Bördelrandes 2 des Eimers aufsteht, wie das in der Figur 1 dargestellt ist.It is now particularly expedient to arrange the opening 7 in the end section 6a such that the distance between it and the adjacent end edge 6c 7T. B, and at the same time gives the ring such a shape that the end edge 6c of the end section 6a abuts the eyelet 8. This means that the radius of the open ring is larger than the radius of the closed ring, in other words that the opened ring 6 sits so loosely on the edge of the cover 3 that it does not fall off and that its lower edge 6d stands approximately on the center of the flange edge 2 of the bucket, as shown in FIG. 1.

In dieser Lage wird nun der Ring mittels einer der erfindungsgemässen Schliessvorrichtungen geschlossen:

  • Die in der Figur 5 dargestellte Schliessvorrichtung weist ein kreisringförmiges Band 11 aus nicht-dehnbarem Material, also beispielsweise aus Federstahl, auf, das auf seiner Innenseite mit einzelnen gegeneinander gerichteten Zungen 12 versehen ist. Am einen Ende 11 des Bands 11 ist ein Spannhebel 13 schwenkbar befestigt, am anderen Ende 11 ein Verbindungshebel 14, dessen anderes Ende am Spannhebel 13 angelenkt ist. Zum Verschliessen eines Eimers wird nun der mit dem Spannring 6 versehene Deckel 3 so, wie das in der Figur 1 dargestellt ist, in die Eimeröffnung eingelegt. Dann wird der Deckel ganz in die Eimeröffnung hinein gedrückt, was ohne weiteres von Hand gemacht werden kann. Dann legt man die vorstehend beschriebene und in der Figur 5 dargestellte Verschliess-Einrichtung in geöffnetem Zustand auf den Deckelrand und den Spannring und schliesst sie durch Verschwenken des Spannhebels 13, wodurch auch der Spannring 6 zusammengedrückt wird, so dass die Öffnung 7 über die Öse 8 gebracht und die Öse 8 durch die Öffnung 7 hindurchgedrückt wird. In dieser Stellung wird der Sicherungsstift 9 eingestossen. Anstelle dieses Stifts kann auch eine Plombierschnur oder ein anderes den Verschluss sicherndes Element verwendet werden.
In this position, the ring is now closed by means of one of the closing devices according to the invention:
  • The closing device shown in FIG. 5 device has an annular band 11 made of non-stretchable material, for example spring steel, which is provided on its inside with individual tongues 12 directed towards each other. At one end 11 of the band 11, a tension lever 13 is pivotally attached, at the other end 11 a connecting lever 14, the other end of which is articulated on the tension lever 13. To close a bucket, the cover 3 provided with the clamping ring 6 is now inserted into the bucket opening as shown in FIG. 1. Then the lid is pushed all the way into the bucket opening, which can easily be done by hand. Then, in the open state, the closing device described above and shown in FIG. 5 is placed on the edge of the lid and the clamping ring and is closed by pivoting the clamping lever 13, which also compresses the clamping ring 6, so that the opening 7 via the eyelet 8 brought and the eyelet 8 is pushed through the opening 7. In this position the locking pin 9 is pushed in. Instead of this pin, a sealing cord or another element securing the closure can also be used.

Die Figuren 6 und 7 zeigen eine andere zum Schliessen des erfindungsgemässen Spannrings dienende Schliessvorrichtung, die besonders gut zum Einbau in eine Eimer-Abfüll- und Verschliessstrasse geeignet ist. Zum Abstellen der gefüllten und zu verschliessenden Eimer 20 dient hier eine mit Positionierungshilfen versehene horizontale Abstellplatte 21, wobei als Positionierungshilfen beispielsweise konzentrische Kreisrillen 21 dienen können, die den gleichen Durchmesser haben wie die Bodenkanten 20a der zu verschliessenden Eimer 20.FIGS. 6 and 7 show another closing device which serves to close the clamping ring according to the invention and which is particularly well suited for installation in a bucket filling and closing line. A horizontal storage plate 21 provided with positioning aids is used to set down the filled and to be closed buckets 20, wherein concentric circular grooves 21, which have the same diameter as the bottom edges 20a of the buckets 20 to be closed, can serve as positioning aids.

Oberhalb dieser Abstellplatte 21 befindet sich ein als Ganzes mit 22 bezeichneter, vertikal verschiebbarer Schliesskopf der an einem oder an zwei Bolzen 23 aufgehängt ist, auf den bzw. auf die mittels eines Handhebels oder einer pneumatischen Vorrichtung die Auf- und Abwärtsbewegung übertragen wird. Ein Anschlag wird entsprechend der Höhe der zu verschliessenden Eimer 20 so angebracht, dass die Abwärtsbewegung des Schliesskopfs 22 weder eine Beschädigung des Eimers 20 noch seines Deckels 24 zur Folge haben kann. Dieser Schliesskopf 22 weist einen zylinderartigen, aber mit einer Aussparung versehenen, im Grundriss also etwa C-förmigen Körper 25 auf, der oben mit einem an dem oder an den Bolzen 23 befestigten Deckel 26 abgeschlossen ist. Die Innenfläche dieses C-förmigen Körpers 25 besitzt einen sich nach unten konisch erweiternden Abschnitt 25a, an den sich an seinem oberen Ende ein zylindrischer Abschnitt 25b anschliesst. Mittels zweier oder dreier je in einer Hülse 27 verschiebbarer Stifte 28 ist am Zylinder-Deckel 26 ein Ring 29 aufgehängt. Sein Aussendurchmesser ist, wie man aus den Figuren 6 und 7 ersehen kann, um ein weniges kleiner als der Innendurchmesser des durch den Spannring 30 zu sichernden Eimerdekkels 24. Dieser Ring 29 lässt sich entgegen der Kräfte von Federn 31 nach oben gegen den Zylinderdeckel 26 hin verschieben.Above this storage plate 21 there is a, as a whole, 22, vertically displaceable closing head which is suspended from one or two bolts 23, to which the up and down movement is transmitted by means of a hand lever or a pneumatic device. A stop is attached according to the height of the buckets 20 to be closed in such a way that the downward movement of the closing head 22 cannot damage the bucket 20 or its lid 24. This closing head 22 has a cylinder-like body 25, but provided with a recess, which is approximately C-shaped in plan view, which is closed at the top with a cover 26 attached to or on the bolts 23. The inner surface of this C-shaped body 25 has a downwardly conically widening section 25a, which is adjoined at its upper end by a cylindrical section 25b. A ring 29 is suspended from the cylinder cover 26 by means of two or three pins 28, each of which can be displaced in a sleeve 27. As can be seen from FIGS. 6 and 7, its outside diameter is a little smaller than the inside diameter of the bucket cover 24 to be secured by the clamping ring 30. This ring 29 can be pushed upwards against the forces of springs 31 against the cylinder cover 26 move.

Eine solche Anordnung wird man in einer Eimer-Abfüll- und Schliessanlage nach der Eimerabfüllstation anordnen und zwar so, dass jeder Eimer zuerst durch eine Zufuhrvorrichtung mit einem Deckel 24 versehen wird, der einerseits von einem Spannring 30 umgeben ist, bevor der Eimer 20 auf die Abstellplatte 21 gelangt. Wenn dann der Eimer 20 auf die Abstellplatte 21 angelangt und dort richtig positioniert ist, wird der Schliesskopf 22 von Hand oder automatisch oder halbautomatisch, d.h. durch Handauslösung beispielsweise einer pneumatischen Einrichtung nach unten verschoben, so dass der Ring 29 auf den Eimerdeckel 24 zu liegen kommt. Beim weitern Abwärtsschieben drückt dieser Ring 29 als Deckelschliesser den Eimerdeckel 24 ganz in den Eimer 20 hinein; beim anschliessenden Weiterschieben des Kopfs 22 bleibt der Ring 29 auf dem Deckel 24 stehen und der C-förmige Körper 25 bewegt sich weiter nach unten. Dadurch gleitet seine konische Innenfläche 25a über den Spannring 30 und verkleinert dessen Radius, bis der Spannring den kleinstmöglichen Umfang angenommen hat, wie das in den Figuren 2, 4 und 7 dargestellt ist. Nun kann man den Spannring durch das Einstecken eines Sicherungsstifts 9 in dieser Lage sichern und den Schliesskopf 22 wieder hochziehen.Such an arrangement will be arranged in a bucket filling and closing system after the bucket filling station in such a way that each bucket is first provided with a lid 24 by a feed device, which is surrounded on the one hand by a clamping ring 30 before the bucket 20 is on the Parking plate 21 arrives. Then when the bucket 20 arrives on the storage plate 21 and is correctly positioned there, the closing head 22 is operated manually or automatically or semi-automatically, i.e. by manual triggering, for example, a pneumatic device moved downward so that the ring 29 comes to rest on the bucket lid 24. When pushed further down, this ring 29, as a lid closer, presses the bucket lid 24 all the way into the bucket 20; when the head 22 is then pushed further, the ring 29 remains on the cover 24 and the C-shaped body 25 moves further downward. As a result, its conical inner surface 25a slides over the clamping ring 30 and reduces its radius until the clamping ring has assumed the smallest possible circumference, as is shown in FIGS. 2, 4 and 7. Now you can secure the clamping ring in this position by inserting a locking pin 9 and pull up the closing head 22 again.

Aus dem vorstehend beschriebenen ergibt sich, dass der erfindungsgemässe Spannring gegenüber den bisher üblichen, mit einem Spannverschluss versehenen Spannringen nicht nur den Vorteil der Materialersparnis bei der Herstellung hat, sondern auch den Vorteil einer wesentlich grösseren Sicherheit im Gebrauch:

  • Einerseits ist es möglich mit der erfindungsgemässen Schliessvorrichtung höhere Schliesskräfte zu erzeugen als mit einem am Spannring angeordneten Spannverschluss mit seinem doch relativ kurzen Spannhebel, so dass der Deckel dichter und sicherer mit dem Eimer verbunden ist. Andererseits ist der erfindungsgemässe Spannring frei von vorstehenden Teilen, die bei Transportunfällen, also beispielsweise bei irgendwelchen Stürzen hängenbleiben und sich dann öffnen können, und von angeschweissten Teilen, die bei Transportunfällen wegbrechen können und dann ebenfalls ein Öffnen des Spannrings zur Folge haben.
It follows from the above-described that the tension ring according to the invention has not only the advantage of saving material during manufacture, but also the advantage of considerably greater safety in use, compared to the tension rings provided previously with a tension lock:
  • On the one hand, it is possible to generate higher closing forces with the closing device according to the invention than with a clamping lock arranged on the clamping ring with its relatively short clamping lever, so that the lid is connected to the bucket more tightly and securely. On the other hand, the tension ring according to the invention is free of protruding parts which get caught in transport accidents, for example in the event of a fall and can then open, and of welded-on parts which can break away in transport accidents and then likewise result in the tension ring being opened.

Eine durch den neuen Spannring verbesserte Sicherheit ist besonders für Eimer wichtig, in denen sogenanntes Gefahrengut enthalten ist, also irgendwelche Flüssigkeiten oder pastöse Massen oder auch Granulate, die beim unbeabsichtigten Austreten Umweltschäden verursachen können.Improved safety due to the new clamping ring is particularly important for buckets in which a so-called dangerous good is contained, i.e. any liquids or pasty masses or granules that can cause environmental damage if they escape unintentionally.
