Description

Die Erfindung bezieht sich auf eine Kompaktierpresse für mit Rahmen umgebene Abluftfilter mit hydraulisch auf den Pressentisch wirkenden Kolben sowie einem feststehenden Pressenoberteil und einem dagegen beweglichen Pressenuntertisch bzw. -backen, wobei an beiden Preßbacken mittels zweier Kniehebel gemeinsam eine oder zwei spiegelbildlich angeordnete Quertraversen angelenkt sind, die nach Art einer Kniehebelpresse mittels der Kniehebel gemeinsam durch die Preßbackenbewegung automatisch senkrecht bzw. quer zur Preßrichtung der Backen in Richtung Pressenmitte einrückbar sind.The invention relates to a compacting press for exhaust air filters surrounded by a frame with pistons which act hydraulically on the press table and a fixed upper press part and a press lower table or jaws which can move against it, one or two cross-members arranged in mirror image fashion being articulated on the two press jaws by means of two toggle levers, which can be automatically engaged by means of the toggle lever movement by means of the toggle lever movement perpendicularly or transversely to the pressing direction of the jaws in the direction of the center of the press.

Das Ausschleusen von sperrigen, zum Teil kontaminierten Gegenständen wie mit Rahmen umgebenen Abluftfiltern aus sog. Heißen Zellen-Anlagen z.B. in der Kerntechnik ist ein bisher unbefriedigend gelöstes Problem. Zu diesem Zweck sollen die Filter kompaktiert bzw. verdichtet werden, so daß jeweils mehrere Zusammen in einen Transportbehälter geschleust und mit diesem abtransportiert werden können.The removal of bulky, partially contaminated objects such as exhaust air filters surrounded by frames from so-called hot cell systems e.g. in nuclear technology is a previously unsatisfactorily solved problem. For this purpose, the filters are to be compacted or compressed, so that several can be put together in a transport container and transported away with it.

Aus der DE-A-15 42 508 ist eine Hochdruckpresse bekannt, die senkrecht von oben nach unten wirkende Hauptambosse bzw. Druckplatten aufweist, an deren Grundplatte mit Hilfe von Kniehebeln jeweils oben und unten angelenkte weitere seitliche Backen angelenkt sind, die senkrecht zur Hauptpreßrichtung von der Seite her Richtung Preßmitte wirken. Diese seitlich wirkenden Backen können jedoch nur eine einfache Bewegung ausführen, die beim Zusammenfahren der Presse aus einem Einschwenken und beim Auseinanderfahren derselben in einem Ausschwenken bestehen. Beim Zusammenpressen von gerahmten Abluftfiltern erweist es sich jedoch als besonders nachteilig, daß damit kein besonders günstig geformter Preßling, der sich in Standardabfallfässern verpacken läßt, erzielt werden kann.From DE-A-15 42 508 a high pressure press is known which has main anvils or pressure plates acting vertically from top to bottom, on the base plate of which further articulated lateral jaws are articulated with the aid of toggle levers, which are perpendicular to the main pressing direction of act from the side towards the press center. However, these laterally acting jaws can only perform a simple movement, which consists of swiveling in when the press is moved together and swiveling out when the press is moved apart. When compressing framed exhaust air filters, however, it proves to be particularly disadvantageous that a particularly cheaply shaped compact which can be packaged in standard waste drums cannot be achieved with it.

Hier will die vorliegende Erfindung Abhilfe schaffen. Aufgabe dieser Erfindung ist es, eine Presse anzugeben, mit welcher sich ein mit einem Rahmen versehener Abluftfilter in eine besonders günstige, kompakte Form bringen läßt.The present invention seeks to remedy this. The object of this invention is to provide a press with which an exhaust air filter provided with a frame can be brought into a particularly favorable, compact form.

Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst diese Aufgabe dadurch, daß der bzw. die unteren Kniehebel um einen Drehpunkt schwenkbar an einem Nocken mitangelenkt sind, der seinerseits um einen weiteren Drehpunkt drehbar in einer Ausnehmung des unteren Pressenbackens befestigt ist und der mittels eines, an einem dritten Anlenk- bzw. Drehpunkt angreifenden Federelements abhängig von seiner jeweiligen Lage. um seinen Drehpunkt im Backen jeweils in Richtung Pressenmitte bzw. Pressenaußenseite drehbar ist und daß der Nocken eine zur Pressenmitte gerichtete Nockenfläche aufweist, die gegen eine schräge Anlauffläche der Aussparung gerichtet und beim Drehen des Nockens in Richtung Pressenmitte an diese zur Anlage schwenkbar ist. Weitere besonders vorteilhafte Merkmale gemäß der vorliegenden Erfindung sind in den Ansprüchen enthalten.The invention, as characterized in the claims, achieves this object in that the lower toggle lever (s) are pivotally pivoted about a pivot point on a cam, which in turn is fastened in a recess of the lower press jaw about a further pivot point and by means of a spring element acting on a third articulation or pivot point depending on its respective position. is rotatable about its pivot point in the jaw in the direction of the press center or the outside of the press and that the cam has a cam surface directed towards the press center, which is directed against an oblique contact surface of the recess and, when the cam is rotated in the direction of the press center, can be pivoted to the system for this purpose. Further particularly advantageous features according to the present invention are contained in the claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß sich mit Hilfe der durch die Erfindung vorgeschlagenen Presse handelsübliche, mit Rahmen versehene Filter zu kompakten Presslingen verarbeiten lassen. Andererseits ist die Presse selbst so kompakt ausgebildet, daß sie sich ohne weiteres in handelsüblichen Fässern transportieren läßt, die allgemein zum Ein- und Ausschleusen von Gegenständen in die erwähnten Heißen Zellen-Anlagen verwendet werden.The advantages achieved by the invention are essentially to be seen in the fact that, with the help of the press proposed by the invention, commercially available, frame-provided filters can be processed into compact compacts. On the other hand, the press itself is so compact that it can be easily transported in commercially available drums which are generally used to inject and discharge objects into the hot cell systems mentioned.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigen

  • die Fig. 2 die Vorrichtung nach dem Pressen und
  • die Fig. 3 eine Draufsicht auf die Fig. 1 und 2 sowie

The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. Show it
  • 1 is a side view of the press before the pressing process and
  • 2 shows the device after pressing and
  • 3 is a plan view of FIGS. 1 and 2 as well
  • 4a to f the function of the buckling device for the frame of the filter to be pressed or compacted in half.

Die in den Fig. 1 bis 3 dargestellte Pressvorrichtung soll einerseits speziell radioaktiv verseuchte Filter 1 kompaktieren, andererseits selbst so kompakt sein, daß sie durch gebräuchliche Schleusöffnungen sogenannter Heißer Zellen ein- bzw. ausgebracht werden kann.The press device shown in FIGS. 1 to 3 is intended on the one hand to compact specially radioactive contaminated filter 1 and on the other hand to be so compact that it can be inserted or removed through the usual lock openings of so-called hot cells.

Zwischen dem unteren Pressbacken 2 bzw. Pressentisch und dem oberen Backen 3 befindet sich der eingelegte Filter 1, der normalerweise aus vielfach gefaltetem Filtergewebe besteht, welches gewöhnlich von einem Holzrahmen 4 umgeben ist. Der untere Pressbacken bzw. Pressentisch 2 wird hydraulisch gegen den oberen 3 gepreßt, so daß der Filter 1 auf ein geringeres Volumen kommt-wie in Fig. 2 gezeigt-gebracht wird.Between the lower press jaw 2 or press table and the upper jaw 3 there is the inserted filter 1, which normally consists of filter fabric which has been folded many times and which is usually surrounded by a wooden frame 4. The lower press jaw or press table 2 is pressed hydraulically against the upper 3, so that the filter 1 has a smaller volume, as shown in FIG. 2.

Der obere Pressbacken 3 ist mittels der Führungsanker 5 und 6 fest mit der Bodenplatte 7 verbunden. In dieser Bodenplatte 7 sind weiterhin die Kolbenstangen 8 und 9 verankert, die an ihrem oberen Ende mit Kolbenringen versehene Kolben 10 und 11 aufweisen. Die Kolben 10 und 11 gleiten in Zylinderräumen 12 und 13, die in dem Zylinderaufnahmestück 14 eingebracht sind. Das Zylinderaufnahmestück 14 ist an seinem unteren Ende fest mit dem unteren Pressbacken 2 verbunden und am oberen Ende in der Platte 16 gelagert, die gleichzeitig den Boden 17 der Zylinder 12, 13 bildet Die Teile 8 bis 14, d.h. die Elemente des hydraulischen Antriebs sind jeweils doppelt also auf jeder Seite einmal vorhanden und demnach paarweise an den Außenseiten der Pressbacken 2 und 3 angeordnet, so daß sich der zusammenzupressende Filter nach Entfernung einer der seitlichen Quertraversen 18 dazwischen einlegen läßt.The upper press jaw 3 is firmly connected to the base plate 7 by means of the guide anchors 5 and 6. The piston rods 8 and 9 are further anchored in this base plate 7 and have pistons 10 and 11 provided with piston rings at their upper end. The pistons 10 and 11 slide in cylinder spaces 12 and 13 which are introduced into the cylinder receiving piece 14. The cylinder receiving piece 14 is fixedly connected at its lower end to the lower press jaw 2 and is supported at the upper end in the plate 16, which at the same time forms the bottom 17 of the cylinders 12, 13. The parts 8 to 14, ie the elements of the hydraulic drive, are each double So once on each side and therefore arranged in pairs on the outside of the pressing jaws 2 and 3, so that the filter to be compressed can be inserted between one after removal of one of the lateral cross members 18.

Das Zylinderaufnahmestück 14 durchdringt dabei den oberen Pressbacken 3 in einer seitlichen Ausnehmung 15, so daß sich bei Hochbewegen des Zylinderaufnahmestükkes 14 die beiden Pressbacken 2 und 3 aneinanderlegen bzw. der dazwischenliegende Filter 1 kompaktiert wird.The cylinder receiving piece 14 penetrates the upper pressing jaw 3 in a lateral recess 15, so that when the cylinder receiving piece 14 is moved up, the two pressing jaws 2 and 3 abut one another or the filter 1 in between is compacted.

Um ein Auseinanderlaufen des gepressten Filters zu verhindern, muß der Filterrahmen 4 vor Beginn des Pressvorganges von außen nach innen eingeknickt bzw. eingekerbt werden, damit sich der Filter zu einem kompakten Pressling kompaktieren läßt. Dies geschieht mit der an der Presse angebrachten, in den Fig. 4a bis 4f genauer dargestellten, zusätzlichen Einknick- bzw. Einkerbvorrichtung.In order to prevent the pressed filter from running apart, the filter frame 4 must be kinked or notched from the outside inwards before the pressing process begins, so that the filter can be compacted into a compact compact. This is done with the additional buckling or notching device attached to the press and shown in more detail in FIGS. 4a to 4f.

Das Hauptelement dieser Kerbvorrichtung sind die beiden spiegelbildlich an beiden Seiten der Presse angeordneten Quertraversen 18, die nach innen zum Filter 1 bzw. zur Pressenmitte 32 hingerichtete Schneidkanten 19 aufweisen und die an den Kniehebeln 20 und 21 schwenkbar befestigt sind. Der Antrieb der Kniehebel ist der Übersichtlichkeit halber in den Fig. 1 bis 3 weggelassen, jedoch im Detail in den Fig. 4a bis 4f rechtshälftig gezeigt. Die Kniehebel 20 und 21 sind an ihren anderen Enden an den beiden Pressbacken 3 und 2 befestigt, der obere Kniehebel 20 dabei mittels des abschraubbaren Zwischenstückes 22, der untere auf ähnliche Weise. Durch Entfernen des Zwischenstückes 22 können die Quertraversen 18 leicht abgebaut bzw. weggeschwenkt werden, um zu Transportzwecken den Umfang der Presseinrichtung zu reduzieren oder um den zu kompaktierenden Filter zwischen die Pressbacken einlegen zu können.The main element of this notching device are the two cross members 18, which are arranged in mirror image on both sides of the press, which have cutting edges 19 directed inwards towards the filter 1 or the press center 32 and which are pivotably attached to the toggle levers 20 and 21. For the sake of clarity, the drive of the toggle levers is omitted in FIGS. 1 to 3, but is shown in detail in the right half in FIGS. 4a to 4f. The toggle levers 20 and 21 are attached at their other ends to the two pressing jaws 3 and 2, the upper toggle lever 20 by means of the unscrewable intermediate piece 22, the lower in a similar way. By removing the intermediate piece 22, the crossbeams 18 can be easily dismantled or pivoted away in order to reduce the size of the pressing device for transport purposes or to be able to insert the filter to be compacted between the pressing jaws.

In den Figuren 4a bis 4f sind für identische Teile dieselben Positionsnummern wie in den Fig. 1 bis 3 verwendet. Der obere Kniehebel 20 ist mit seinem oberen Ende um den Drehpunkt 23 schwenkbar am oberen Pressbacken 3 und mit seinem unteren Ende um den Drehpunkt 24 an der Quertraverse 18 angelenkt. Der untere Kniehebel 21 ist mit seinem oberen Ende ebenfals an der Traverse 18 um den Drehpunkt 25 angelenkt, an seinem unteren Ende 26 jedoch um den weiteren Drehpunkt 29 drehbar an den Betätigungsnocken 27, der seinerseits um einen erneuten Drehpunkt 28 drehbar an dem unteren Pressbacken befestigt ist. Die beiden Kniehebel 20 und 21 mit den Quertraversen 18 bilden somit, da sie um die Drehpunkte 23 und 29 an den Pressbacken bzw. 24 und 25 an der Quertraverse schwenkbar sind, eine seitliche Zusatzpresseinrichtung ähnlich einer Kniehebelpresse, d.h. beim Gegeneinanderfahren der Pressbacken 2 und 3 drücken die Kniehebel 20 und 21 die Quertraverse 18 mit ihrer Schneidkante 19 nach innen in Richtung Pressenmitte 32 bzw. gegen den Filterrahmen 4. Damit diese Bewegung beim Zusammenfahren zunächst zwangsläufig erfolgt, wird auf den Nocken 27 an einem exzentrisch zum Nockendrehpunkt 28 gelegenen weiteren Dreh- bzw. Anlenkpunkt 30 eine Zugkraft 31 angelegt, die den Nocken in Richtung Pressenmitte 32-bei der gezeichneten Ausführungsform gegen den Uhrzeigersinn-zu drehen sucht. Diese Kraft 31 wird durch das beweglich am unteren Pressbacken 2 angelenkte Zugfederelement 33 erzeugt. Wie bereits erwähnt, ist der Nocken 27 um seine Achse 28 drehbar in einer Aussparung 34 des unteren Pressbackens 2 gelagert. Die Aussparung 34 wird zur Pressenmitte 32 hin durch die schräg nach oben/innen verlaufende Anlauffläche 35 begrenzt, gegen die sich der Nokken 27 bis zum Anlegen seiner zur Pressenmitte 32 gerichteten Nockenfläche 36 drehen läßt. Am oberen Ende der Anlauffläche 35 befindet sich noch eine Nase 37 als Anschlagsbegrenzung, bis zu welcher sich der unteren Kniehebel 21 in Richtung Pressenmitte 32 schwenken läßt.In FIGS. 4a to 4f, the same item numbers as in FIGS. 1 to 3 are used for identical parts. The upper toggle lever 20 is pivoted at its upper end about the pivot point 23 on the upper press jaw 3 and at its lower end about the pivot point 24 on the crossbar 18. The lower toggle lever 21 is also articulated with its upper end on the crossbeam 18 about the pivot point 25, but at its lower end 26 it is rotatable about the further pivot point 29 on the actuating cam 27, which in turn is rotatably fastened to the lower press jaw about a further pivot point 28 is. The two toggle levers 20 and 21 with the crossbeams 18 thus, since they can be pivoted about the pivot points 23 and 29 on the press jaws or 24 and 25 on the crossbeam, form a lateral additional pressing device similar to a toggle lever press, i.e. when the pressing jaws 2 and 3 move against each other, the toggle levers 20 and 21 press the crossbar 18 with their cutting edge 19 inwards towards the press center 32 or against the filter frame 4. So that this movement inevitably takes place when moving together, the cam 27 becomes eccentric on one a tensile force 31 is applied to the further fulcrum or articulation point 30 located at the cam fulcrum 28 and attempts to rotate the cam in the direction of the press center 32 — counterclockwise in the embodiment shown. This force 31 is generated by the tension spring element 33 articulated on the lower press jaw 2. As already mentioned, the cam 27 is mounted rotatably about its axis 28 in a recess 34 in the lower press jaw 2. The recess 34 is bounded towards the press center 32 by the run-up surface 35 which runs obliquely upwards / inwards, against which the cam 27 can be rotated until its cam surface 36 directed towards the press center 32 is in contact. At the upper end of the contact surface 35 there is also a nose 37 as a limit stop, up to which the lower toggle lever 21 can be pivoted in the direction of the press center 32.

Die Funktion der Presseinrichtung ist nun wie folgt, wobei sich dieselben Baulemente spiegelbildlich auch an der linken Seite der Presse befinden, die in den Fig. 4a bis 4f nicht dargestellt ist:

  • Fig. 4a: Der Filter 1 ist zwischen die Pressbacken 2 u. 3 beigelegt. Der hydraulische Antrieb 8 bis 14 erzeugt die Bewegung in Pfeilrichtung 39 und 40. Durch die Zugkraft 31 wird der Nocken 27 nach innen gezogen, die Kniehebel 20 und 21 sind in Richtung der Pfeile 38 gespannt.
  • Fig. 4b: Der Nocken 27 kommt mit der Nockenfläche 36 zum Anliegen an die Anlauffläche 35 und somit zum Stillstand. Auf die Quertraverse 18 werden Druckkräfte 41 und 42 ausgeübt, die dieselbe nach innen drücken.
  • Fig. 4c u.d: Die Schneidkanten 19 der Traversen 18 knicken den Rahmen 4 des Filters 1 nach innen bis die unteren Kniehebel 21 an der Nase 37 zur Anlage bzw. zum Stillstand kommen.
  • Fig. 4e: Der untere Kniehebel 21 wird dadurch wieder nach außen gedrückt. Der Nocken 27 dreht sich um den Drehpunkt 28 bis der weitere Drehpunkt 30 unterhalb diesen zu liegen kommt und die Kraft 31 die Kniehebel 20 und 21 mit der Traverse 18 wiederum nach außen zieht. Der Filter 1 wird dabei durch die Kräfte 39 und 40 kompaktiert.
  • Fig. 4f: Der Filterrahmen 4 ist eingeknickt und der Filter 1 kompaktiert, die Pressbacken 2 und 3 befinden sich in der oberen Totpunktstellung, die Traverse 18 zu den Kniehebeln 20 und 21 ist automatisch nach außen weggeklappt. Nach Zurückfahren in die Ausgangsstellung 4a kann der kompaktierte Filter nach Wegklappen der Quertraversen 18 entnommen und ein neuer eingelegt werden.
    Figure imgb0001
The function of the press device is now as follows, the same structural elements also being mirror images on the left side of the press, which is not shown in FIGS. 4a to 4f:
  • Fig. 4a: The filter 1 is between the press jaws 2 u. 3 enclosed. The hydraulic drive 8 to 14 generates the movement in the direction of the arrows 39 and 40. The cam 27 is pulled inwards by the tensile force 31, the toggle levers 20 and 21 are tensioned in the direction of the arrows 38.
  • Fig. 4b: The cam 27 comes with the cam surface 36 to the abutment surface 35 and thus comes to a standstill. Compression forces 41 and 42 are exerted on the crossbeam 18, which push the same inwards.
  • Fig. 4c ud: The cutting edges 19 of the traverses 18 bend the frame 4 of the filter 1 inwards until the lower toggle levers 21 come to rest on the nose 37 or come to a standstill.
  • Fig. 4e: The lower toggle lever 21 is pressed outwards again. The cam 27 rotates about the pivot point 28 until the further pivot point 30 comes to lie below it and the force 31 in turn pulls the toggle levers 20 and 21 with the cross member 18 outwards. The filter 1 is compacted by the forces 39 and 40.
  • Fig. 4f: The filter frame 4 is buckled and the filter 1 compacted, the press jaws 2 and 3 are in the top dead center position, the cross member 18 to the toggle levers 20 and 21 is automatically folded outwards. After returning to the starting position 4a, the compacted filter can be removed after the cross-members 18 have been folded away and a new one can be inserted.
