Abstract

A baling press for fibrous materials, such as textile fibers, is equipped with a baling box into which a baling ram is movable under hydraulic or pneumatic pressure. The baling box is supported on a base and has hinged walls which are hinged to one another and/or to the base. These hingeable box walls are locked to each other in the box closing position by a piston cylinder locking device in which the piston rod is provided at its free end with a locking member which cooperates with a respective locking element attached to the adjacent wall.

Description

Die Erfindung betrifft eine Presse für textile Fasern mit einem Pressenstempel, einem Pressenboden und einem diese seitlich umgebenden Presskastenmantel, dessen Wände aneinander verschwenkbar gelagert und miteinander in der Pressstellung durch eine Verriegelungseinrichtung verriegelbar sind, die aus einer am Ende einer Wand schwenkbar gelagerten Kolbenzylindereinrichtung mit einem Sperrglied besteht, das an der in der Schliessstellung senkrecht dazu angeordneten Kastenwandung anliegt. (vgl. Oberbegriff des Anspruchs 1).The invention relates to a press for textile fibers with a press ram, a press base and a press box casing surrounding it laterally, the walls of which are pivotally mounted to one another and can be locked together in the pressing position by a locking device which consists of a piston-cylinder device with a locking member which is pivotably mounted at the end of a wall exists that bears against the box wall arranged perpendicular to it in the closed position. (see preamble of claim 1).

Pressen der genannten Art sind in verschiedenen Ausführungsformen bekannt und dienen insbesondere zum Herstellen grosser Ballen aus kurzen oder langen Fasern. Während des Pressens verdichten sich die Fasern im Pressenkasten und drücken mit verhältnismässig grosser Kraft gegen die Kastenwände, wodurch häufig Schwierigkeiten beim Öffnen der Verriegelungseinrichtung auftreten. Diese steht nach dem Pressvorgang unter einer solch hohen Vorspannung, dass sie sich nur schwer öffnen lässt.Presses of the type mentioned are known in various embodiments and are used in particular for producing large bales from short or long fibers. During the pressing, the fibers in the press box become denser and press against the box walls with a relatively great force, which often causes difficulties when opening the locking device. After the pressing process, it is under such high prestress that it is difficult to open.

Durch die FR-A-2 297 217 ist eine Presse für Textilfasern anfangs genannter Art bekannt. Wichtig für eine solche Vorrichtung zum Verschliessen der Pressenkastenmantelwände ist, dass sie in ihrer Funktion einfach und damit robust aufgebaut ist, dass sie beim Pressen die Kammerwände auch gegen den mehrere Tonnen grossen Innendruck aneinander festhält und sie nach dem Pressvorgang ein voneinander Entfernen der Pressenkastenmantelwände bei unter Pressdruck stehendem Ballen ermöglicht, ohne dass dabei Teile zerstört werden oder die Pressenkastenmantelwände mit hörbarem Geräusch infolge des hohen Pressdruckes voneinander weg schwingen. Der Schliessmechanismus nach der französischen Veröffentlichung wird auf die Dauer diesen Anforderungen nicht gerecht. Die Konstruktion der Verriegelungseinrichtung ist sehr aufwendig. Auch ist die Anlage der Verschlussstange an der benachbarten Schliesswand nur kurze Zeit nach dem beginnenden Öffnen der Verriegelungsvorrichtung gewährleistet, woraufhin sie dann mit Federdruck aufschwingen wird, was eine Gefahr für die die Presse bedienenden Arbeiter bedeutet.FR-A-2 297 217 discloses a press for textile fibers of the type mentioned initially. It is important for such a device for closing the press box jacket walls that its function is simple and therefore robust, that it holds the chamber walls together against the several tons of internal pressure during pressing and that they remove the press box jacket walls from one another after the pressing process Bale standing press pressure allows without destroying parts or swinging the press box jacket walls away from each other with audible noise due to the high press pressure. The locking mechanism after the French publication does not meet these requirements in the long run. The construction of the locking device is very complex. Also, the engagement of the locking bar on the adjacent closing wall is ensured only a short time after the locking device begins to open, whereupon it will then swing open with spring pressure, which means a danger for the workers operating the press.

Eine Lösung für dieses Problem ist auch nicht aus der Vorrichtung nach der DE-A-1 964 862 zu entnehmen. Abgesehen davon, dass die dort beschriebene Vorrichtung zum Herstellen von Hohlkörpern aus thermoplastischem Material keine Berührungspunkte mit Chemiefaserpressen hat, würde die aus dieser Schrift bekannte Verriegelungseinrichtung den oben beschriebenen Anforderungen für eine Presse nicht standhalten. Im verschlossenen Zustand dieser Vorrichtung dient ein Splint zum Verriegeln der Kammerwandung. Zum Öffnen der Verriegelungseinrichtung ist der Zylinder zurückzuziehen, was allein wegen des hohen Pressdruckes bei Chemiefaserpressen nicht möglich ist. Unterstellt, es ginge, so würden sich die miteinander verschlossenen Presskastenwände schlagartig voneinander wegbewegen.A solution to this problem cannot be found in the device according to DE-A-1 964 862 either. Apart from the fact that the device described there for producing hollow bodies from thermoplastic material has no points of contact with chemical fiber presses, the locking device known from this document would not meet the requirements for a press described above. In the closed state of this device, a split pin is used to lock the chamber wall. To open the locking device, the cylinder has to be pulled back, which is not possible with chemical fiber presses simply because of the high pressing pressure. Assuming it would work, the closed press box walls would suddenly move away from each other.

Weiterhin ist noch die US-A-3 099 205 zu erwähnen, deren Vorrichtung ebenfalls der Gattung entspricht. Die hier jedoch starr befestigte Kolbenzylindereinrichtung weist an ihrem Schliessende einen über die zu verschliessende Wandung verschwenkbaren Bügel auf. Der Bügel ist von Hand zu bewegen. Es ist einleuchtend, dass ein Bewegen des Bügels im Presszustand zum Öffnen der Türe nicht möglich ist. Ausserdem ist dazu eine Bedienungsperson erforderlich.Also to be mentioned is US-A-3 099 205, the device of which also corresponds to the genus. The piston-cylinder device, however, rigidly attached here, has at its closing end a bracket that can be pivoted over the wall to be closed. The bracket can be moved by hand. It is obvious that it is not possible to move the bracket in the pressed state to open the door. An operator is also required for this.

Der Erfindung liegt die Aufgabe zugrunde, Massnahmen vorzusehen, um ein einwandfreies selbsttätiges Schliessen und Öffnen der Verriegelungseinrichtung für die aufschwenkbaren Wände des Pressenkastens sicher zu stellen.The invention has for its object to provide measures to ensure a proper automatic closing and opening of the locking device for the swing-open walls of the press box.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, dass am freien Ende des Kolbens der Kolben- zylindereinrichtung das Sperrglied angeordnet ist und die Achse der Kolbenzylindereinrichtung in der Schliessstellung die Ebenen der beiden miteinander verriegelbaren Wände schräg schneidet.To achieve this object, the invention provides that the locking member is arranged at the free end of the piston of the piston-cylinder device and the axis of the piston-cylinder device in the closed position intersects the planes of the two lockable walls at an angle.

Die Verriegelungseinrichtung arbeitet nur kraftschlüssig und hält die miteinander zu verriegelnden Wände allein aufgrund der von der Kolbenzylindereinrichtung aufgebrachten Schliesskraft.The locking device only works non-positively and holds the walls to be locked together solely on the basis of the closing force applied by the piston-cylinder device.

Sobald der Druck in der Kolbenzylindereinrichtung nachlässt, öffnen sich die miteinander verriegelten Wände des Presskastens langsam entsprechend der steuerbaren Bewegung der Kolbenzylindereinrichtung. Hierbei ist es völlig unbeachtlich, wie hoch der Innendruck im Pressenkasten war. Er kann niemals zu einem Verklemmen der Verriegelunseinrichtung führen, wie dies bei mechanisch verriegelnden Einrichtungen der Fall ist.As soon as the pressure in the piston cylinder device decreases, the interlocked walls of the press box slowly open in accordance with the controllable movement of the piston cylinder device. It is completely irrelevant how high the internal pressure was in the press box. It can never cause the locking device to jam, as is the case with mechanically locking devices.

Weitere Merkmale der Erfindung gehen aus der Beschreibung und den Ansprüchen im Zusammenhang mit der Zeichnung hervor.Further features of the invention emerge from the description and the claims in connection with the drawing.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, näher beschrieben. Dabei zeigen:

Eine erfindungsgemässe Presse 1 gern. Figur 1 zum Herstellen von Ballen aus textilen Fasern weist mindestens einen Pressenstempel 2 und einen Pressenkasten 3 auf, dessen Wände 4 und 5 bzw. 6 und 7 an einem Stützrahmen 8 bzw. aneinander schwenkbar angeordnet und miteinander in der Schliessstellung verriegelbar sind. Das obere Ende der Presse 1 ist ebenso wie der Antrieb für den Pressenstempel 2 in den Figuren nicht dargestellt, da diese Teile grundsätzlich bekannt und nicht Gegenstand der Erfindung sind.A press 1 according to the invention. Figure 1 for the manufacture of bales from textile fibers has at least one press ram 2 and a press box 3, the walls 4 and 5 or 6 and 7 of which are pivotably arranged on a support frame 8 or against one another and can be locked together in the closed position. The upper end of the press 1 is like the drive for the press die 2 in the figures not shown, since these parts are generally known and are not the subject of the invention.

Die beiden einander gegenüber stehenden Wände 4 und 5 des Pressenkasten 3 sind voneinander weg schwenkbar am Stützrahmen 8 auf Achsen 9, 10 gelagert. Die Wand 6 ist an der einen Wand 5 um eine Achse 11 schwenkbar gelagert und die letzte Wand 7 ist mit Hilfe von Lenkern 12, 13, 14 und 15 an den beiden sich gegenüber stehenden Wänden 4 und 5 angelenkt. Wenn die beiden Wände 4 und 5 daher aus der Schliessstellung gemäss Figur 2 in die geöffnete Stellung gemäss Figur 3 auseinander schwenken, bewegt sich die Wand 7 senkrecht zu ihrer Ebene ein Stück nach aussen. Die die Wand 7 tragenden Lenker 12-15 sind zweckmässigerweise bogenförmig, wie aus den Figuren hervorgeht.The two opposing walls 4 and 5 of the press box 3 are pivotally mounted on the support frame 8 on axes 9, 10. The wall 6 is mounted on the one wall 5 so as to be pivotable about an axis 11 and the last wall 7 is articulated on the two opposing walls 4 and 5 with the aid of links 12, 13, 14 and 15. If the two walls 4 and 5 therefore pivot apart from the closed position according to FIG. 2 into the open position according to FIG. 3, the wall 7 moves a bit outwards perpendicularly to its plane. The handlebars 12-15 carrying the wall 7 are expediently curved, as can be seen from the figures.

Die Wand 6 ist relativ zur Wand 5 nur um wenige Grad verschwenkbar gelagert und gemäss Ausführungsbeispiel mit einer Verriegelungseinrichtung 16 versehen. Diese Verriegelungseinrichtung 16 besteht aus Kolben-Zylindereinrichtungen 17, die schwenkbar an der Wand 5 gelagert sind und je ein Sperrglied 18 an ihrem freien Ende 19 aufweisen. Zweckmässigerweise sind zwei Kolben-Zylindereinrichtungen 17 an der Wand 6 in Konsolen 20 bzw. 21 um Achsen 22 bzw. 23 verschwenkbar gelagert und lassen sich mit Hilfe von Kolben- Zylindereinrichtung 24 aus der in Figur 2 dargestellten Schliessstellung in die in Figur 3 wiedergegebene Stellung «auf» verschwenken.The wall 6 is only pivotably pivotable by a few degrees relative to the wall 5 and, according to the exemplary embodiment, is provided with a locking device 16. This locking device 16 consists of piston-cylinder devices 17 which are pivotally mounted on the wall 5 and each have a locking member 18 at their free end 19. Two piston-cylinder devices 17 are expediently mounted on the wall 6 in brackets 20 and 21 about axes 22 and 23 and can be moved from the closed position shown in FIG. 2 to the position shown in FIG. 3 with the aid of piston-cylinder device 24. on »swivel.

Das Sperrglied 18 der Verriegelungseinrichtung 16 ist ein starr am freien Ende 19 der Kolbenstange 25 angeordnetes, etwa halbkugelförmiges bzw. balliges Haltestück, dessen Durchmesser grösser ist als der Kolbenstangendurchmesser. Dem Sperrglied bzw. Haltestück 18 mit seiner halbkugelförmigen Haltefläche 26 ist an der anderen Wand 4 ein Halteteil 27 mit einer kalottenförmigen Haltefläche 28 mit einem Eintrittsschlitz 29 zugeordnet. Einzelheiten hierzu sind in den Figuren 3 und 4 dargestellt.The locking member 18 of the locking device 16 is a rigidly arranged at the free end 19 of the piston rod 25, approximately hemispherical or spherical holding piece, the diameter of which is larger than the piston rod diameter. The locking member or holding piece 18 with its hemispherical holding surface 26 is assigned a holding part 27 with a dome-shaped holding surface 28 with an entry slot 29 on the other wall 4. Details of this are shown in FIGS. 3 and 4.

Beim Verschliessen des Pressenkastens 3 tritt die Kolbenstange 25 in den Eintrittsschlitz 29 ein, woraufhin der Kolben in das Innere des Zylinders 30 der Kolben-Zylindereinrichtung 17 verschoben wird. Hierbei legt sich das Haltestück 18 in die kalottenförmige Haltefläche 28 und verschliesst den Pressenkasten kraftschlüssig.When the press box 3 is closed, the piston rod 25 enters the entry slot 29, whereupon the piston is displaced into the interior of the cylinder 30 of the piston-cylinder device 17. Here, the holding piece 18 lies in the dome-shaped holding surface 28 and closes the press box in a force-fitting manner.

Zum Öffnen des Pressenkastens 3 wird zunächst der Schliessdruck im Zylinder 30 allmählich zum Beispiel durch Einschaltung einer Drossel abgesenkt, bis der im Pressenkasten befindliche Ballen keinen Druck mehr auf die Wände 4-7 ausübt. Sodann wird die Kolbenstange 25 nach aussen verschoben, bis sie das Halteteil 27 vollkommen freigegeben hat und die Wände auseinandergeschwenkt werden können.To open the press box 3, the closing pressure in the cylinder 30 is first gradually reduced, for example by switching on a throttle, until the bale in the press box no longer exerts pressure on the walls 4-7. Then the piston rod 25 is moved outwards until it has completely released the holding part 27 and the walls can be pivoted apart.

Alle Teile der Verriegelungseinrichtung 16 sind schliesslich derart angeordnet, dass die Achse bzw. die Achsen 31 (siehe Figur 2) der Kolben-Zylindereinrichtungen 17 in der Schliessstellung die Ebenen 32 bzw. 33 der beiden miteinander verriegelten Wände 4 und 6 schräg schneidet.Finally, all parts of the locking device 16 are arranged in such a way that the axis or the axes 31 (see FIG. 2) of the piston-cylinder devices 17 in the closed position intersect the planes 32 and 33 of the two interlocked walls 4 and 6.

Die Versorgungsleitungen und die Steuereinrichtungen für die verschiedenen Kolben-Zylindereinrichtungen sind in den Figuren der besseren Übersicht wegen nicht dargestellt.The supply lines and the control devices for the various piston-cylinder devices are not shown in the figures for the sake of clarity.

Wie vor allem aus Figur 1 hervorgeht, stützt sich jede der beiden Schwenkachsen 9 bzw. 10 der Wände 4, 5 auf einer Feder 34 ab, die in einer Bohrung 35 im Grundrahmen bzw. Stützrahmen 8 angeordnet ist. Die Wände 4 bzw. 5 sind vorzugsweise starr mit der ihnen zugeordneten Achse 9 bzw. 10 verbunden und werden dadurch von den Federn 34 in einer Richtung vertikal nach oben beaufschlagt bzw. die Wände 4, 5 stützen sich auf den sehr starken Federn 34 ab. Über Konsolen 36-38 sind die Wände 4 und 5 mit den Achsen 9 bzw. 10 verbunden, die in unteren Lagern 39 und oberen Lagern 40 geführt bzw. abgestützt sind. Aus den oberen Lagern 40 greifen die Achsen 9 und 10 noch ein Stück heraus und tragen dort jeweils ein Zahnrad 41 bzw. 42, die über kämmende Zwischenräder 43 und 44 jeweils gegenläufig drehend miteinander verbunden sind. Von dem einen Zahnrad 41 ragt schliesslich noch ein Schwenkhebel 45 weg, der von einer Kolben- Zylindereinrichtung 46 verstellbar ist, die mit ihrem einen Ende 47 am Schwenkhebel 45 und mit ihrem anderen Ende 48 an einem Kastenoberteil 49 der Presse 1 angelenkt ist. Sobald die Kolben- Zylindereinrichtung 46 den Schwenkhebel 45 verschwenkt, öffnen bzw. schliessen die beiden Wände 4 und 5 synchron.As can be seen above all from Figure 1, each of the two pivot axes 9 and 10 of the walls 4, 5 is supported on a spring 34 which is arranged in a bore 35 in the base frame or support frame 8. The walls 4 and 5 are preferably rigidly connected to the axis 9 and 10 assigned to them and are thereby acted upon vertically upwards by the springs 34 or the walls 4, 5 are supported on the very strong springs 34. The walls 4 and 5 are connected to the axes 9 and 10 via brackets 36-38, which are guided or supported in lower bearings 39 and upper bearings 40. From the upper bearings 40, the axles 9 and 10 still pull out a little and each carry a gear 41 and 42, respectively, which are connected to each other in opposite directions via meshing intermediate wheels 43 and 44. Finally, a swivel lever 45 protrudes from the one gear wheel 41, which can be adjusted by a piston-cylinder device 46, which is articulated with its one end 47 on the swivel lever 45 and with its other end 48 on a box upper part 49 of the press 1. As soon as the piston-cylinder device 46 pivots the pivot lever 45, the two walls 4 and 5 open or close synchronously.

Der Stützrahmen 8 ist im wesentlichen U- bzw. jochförmig und umfasst eine Bodenplatte 50 sowie eine Lagerplatte 51, auf der für jede Presskastenwand 4-7 mehrere Druckstücke 52 angeordnet sind. Vorzugsweise sind jeder Wand zwei Druckstücke 52 zugeordnet, wie aus Figur 3 hervorgeht.The support frame 8 is essentially U-shaped or yoke-shaped and comprises a base plate 50 and a bearing plate 51 on which a plurality of pressure pieces 52 are arranged for each press box wall 4-7. Two pressure pieces 52 are preferably assigned to each wall, as can be seen from FIG. 3.

An der Unterseite der Wände 4-7 befinden sich ebenfalls Druckstücke 53 in gleicher Anzahl und liegen in der Schliessstellung gemäss Figur 1 auf den unteren Druckstücken 52 auf, wenn sich der Pressenstempel 2 während eines Arbeitsganges absenkt. Sobald jedoch die Verriegelungseinrichtung 16 geöffnet wurde, heben die Federn 34 über die Achsen 9 und 10 die Wände 4 und 5 und dadurch auch die Wände 6 und 7 soweit an, bis sich die unteren Druckstücke 52 und die oberen Druckstücke 53 nicht mehr berühren und sich die Wände 4-7 frei öffen lassen.On the underside of the walls 4-7 there are also the same number of pressure pieces 53 and, in the closed position according to FIG. 1, rest on the lower pressure pieces 52 when the press ram 2 lowers during an operation. However, as soon as the locking device 16 has been opened, the springs 34 raise the walls 4 and 5 and thus also the walls 6 and 7 via the axes 9 and 10 until the lower pressure pieces 52 and the upper pressure pieces 53 no longer touch and touch let the walls open 4-7.

Bei den Federn 34 handelt es sich um eine Hubeinrichtung, die sicherstellt, dass die Wände 4-7 berührungsfrei öffnen und schliessen.The springs 34 are a lifting device which ensures that the walls 4-7 open and close without contact.

Der Pressenstempel 2 arbeitet im Presskasten 3 gegen einen Boden 54, doch versteht es sich, dass anstelle des starr angeordneten Bodens 54 auch ein unterer, zweiter beweglicher Gegenstempel vorgesehen sein könnte, ohne dass dadurch der Kern der Erfindung verlassen wird. Der Boden 54 ruht auf einem Zwischenstück 55, das sich zwischen den Druckstücken 52, 53 befindet und oben auf der Lagerplatte 51 angeordnet ist.The press die 2 works in the press box 3 against a base 54, but it goes without saying that, instead of the rigidly arranged base 54, a lower, second movable counter-die could also be provided without thereby leaving the core of the invention. The bottom 54 rests on an intermediate piece 55, which is located between the pressure pieces 52, 53 and is arranged on top of the bearing plate 51.

Der U-förmige Stützrahmen weist oberhalb der Lagerplatte 51 bzw. des Bodens 54 sowie seitlich bzw. hinter den Achsen 9 und 10 ein Tragteil 56 auf, dessen oberes Ende 57 horizontal wegragt und die oberen Lager 40 für die Achsen 9 und 10 aufweist und ferner den Kastenoberteil 49 mit dem Pressenstempel 2 trägt.The U-shaped support frame has a support member 56 above the bearing plate 51 or the base 54 and laterally or behind the axes 9 and 10, the upper end 57 of which projects horizontally and the upper bearing 40 for the axes 9 and 10 and further carries the box top 49 with the press ram 2.

Es versteht sich schliesslich, dass in den Figuren aus Platzgründen bzw. im Interesse einer besseren Übersicht eine Vielzahl konstruktiver Einzelheiten nur angedeutet und nicht detailliert dargestellt ist, wie beispielsweise die lediglich prinzipmässig erkennbaren Schwenkachsen 58 und 59 bzw. 60 und 61 der die Wand 7 tragenden Lenker 12 bis 15.Finally, it goes without saying that in the figures, for reasons of space or in the interest of a better overview, a large number of structural details are only indicated and not shown in detail, such as, for example, the pivot axes 58 and 59 or 60 and 61 of the wall 7 that can only be recognized in principle Handlebars 12 to 15.
