Description

Die Erfindung betrifft eine Pressenentleereinrichtung, bestehend aus einem höhenbeweglichen Pressenentleerkorb mit Kettenfördervorrichtung und mehreren, an den Längsseiten des Pressenentleerkorbs angeordneten Auflagen mit einem Schlitzbereich für Pressunterlagen für eine Mehretagenpresse, einer im Schlitzbereich angeordneten Abfördervorrichtung für nacheinander von dem Pressenentleerkorb weitergegebenen Spanplatten.The invention relates to a press emptying device, consisting of a vertically movable press emptying basket with chain conveyor device and a plurality of supports arranged on the long sides of the press emptying basket with a slot area for press supports for a multi-day press, a discharge device arranged in the slot area for particle boards passed in succession from the press emptying basket.

Pressenentleereinrichtungen sind hinter Mehretagenpressen angeordnet, um nach Beendigung des Pressvorgangs eine möglichst rasche Entleerung der Mehretagenpresse zu ermöglichen und unabhängig von dieser eine Weiterförderung fertig gepresster Spanplatten in kontinuierlichem Betrieb durchzuführen. Bisher werden die fertig gepressten Spanplatten einschliesslich ihrer Unterlagen aus der Presse in einem Pressenentleerkorb abgelegt und anschliessend aus diesem einer hinter dem Pressenentleerkorb angeordneten Trennstation zugeführt, in der eine Trennung zwischen fertig gepressten Spanplatten und Unterlagen stattfindet, wobei bei flexiblen Unterlagen die flexiblen Unterlagen nach der Trennung durch einen Abwärtsförderer wieder einem Rückförderer zugeführt werden, der die von den Spanplatten befreiten Unterlagen zur Schüttstation zurückführt (DE-A-16 53 319)Press emptying devices are arranged behind multi-daylight presses in order to enable the multi-daylight press to be emptied as quickly as possible after completion of the pressing process and to carry out further conveying of finished pressed chipboard in continuous operation regardless of this. So far, the finished pressed chipboard including its documents from the press are stored in a press emptying basket and then fed from this to a separation station arranged behind the press emptying basket, in which a separation between the pressed particle board and documents takes place, with flexible documents the flexible documents after the separation are fed back by a downward conveyor to a return conveyor which returns the documents freed from the chipboard to the pouring station (DE-A-16 53 319)

Durch die DE-B-1 104162 ist eine dem Oberbegriff des Anspruchs 1.) entsprechende Pressenentleervorrichtung bekannt geworden. Diese gestattet jedoch nicht, eine einfache Pressenentleerung durchzuführen, da für eine derartige Entleereinrichtung zusätzlich ein Ausfahrbalken vorgesehen sein muss, der durch den dort vorgesehenen freien Schlitzbereich bewegt wird, um gleichzeitig alle mit Spanplatten versehenen Unterlagbleche aus der geöffneten Presse herausziehen zu können. Auch ist hier noch eine zusätzliche Trennstation hinter der Pressenentleereinrichtung erforderlich.From DE-B-1 104162 a press emptying device corresponding to the preamble of claim 1) has become known. However, this does not allow a simple press emptying, since an extension bar must be provided for such an emptying device, which is moved through the free slot area provided there, in order to be able to pull out all of the underlay plates provided with chipboard from the open press at the same time. An additional separation station behind the press emptying device is also required here.

Bei Kleinanlagen führen diese Systeme der Entleerung und Trennung zu erheblichem Aufwand, der sich in der Anlagenlänge und im Maschinenpreis deutlich niederschlägt. Um diesen Nachteil zu beseitigen, liegt der Erfindung die Aufgabe zugrunde, einen Pressenentleerkorb gleichzeitig als Trenneinrichtung für das Trennen von fertig gepressten Spanplatten, von deren flexiblen Unterlagen und als Abwärtsförderer für die leeren abzutransportierenden flexiblen Unterlagen zu verwenden. Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass ein in einer vertikalen Richtung offener Käfig vorgesehen ist, dass für jede Spanplatte und jede zugehörige Pressunterlage ein zugehöriges Kettenförderpaar vorgesehen ist, das zur Abförderung von Spanplatten eine Rollenbahn und zur Ablage der von den Spanplatten abgeschälten flexiblen Pressunterlagen ein in der Mitte ebenfalls offenes Hilfsdeck vorgesehen ist, sowie dass zur Rückführung abgeschälter flexibler Pressunterlagen eine Abfördervorrichtung unterhalb des Käfigs angeordnet ist. Durch diese erfinderische Lösung wird eine zusätzliche Trennung, eine Abwärtsförderung und eine Zuförderung zum Rückförderer für flexible Unterlagen, wie sie der Stand der Technik unbedingt besitzen musste, völlig vermieden; es wird also ein Abschälvorgang, der gleichzeitig in einen Rückführvorgang einmündet, innerhalb der Pressenentleereinrichtung erreicht. Eine Ausgestaltung des Erfindungsgegenstandes besteht darin, dass der Käfig u-förmig und nach unten offen ist. Durch diese Ausgestaltung wird die Befestigung des Abförderers direkt auf dem Fundament ermöglicht, und es kann der u-förmige Käfig an diesem Förderer vorbeibewegt werden.In small systems, these systems of emptying and separation lead to considerable effort, which is clearly reflected in the length of the system and the price of the machine. In order to eliminate this disadvantage, the invention has for its object to use a press emptying basket at the same time as a separating device for separating finished pressed chipboard, its flexible documents and as a downward conveyor for the empty flexible documents to be removed. This object is achieved according to the invention in that a cage which is open in a vertical direction is provided, and that for each chipboard and each associated press pad there is an associated chain conveyor pair which uses a roller conveyor for removing chipboard and for storing the flexible press pads peeled off the chipboard in the middle there is also an open auxiliary deck, and that a return device is arranged below the cage for the return of peeled flexible press documents. This inventive solution completely avoids additional separation, a downward conveyance and a conveyance to the return conveyor for flexible documents, as the state of the art absolutely had to have; a peeling process, which simultaneously leads to a return process, is thus achieved within the press emptying device. One embodiment of the subject matter of the invention is that the cage is U-shaped and open at the bottom. This configuration enables the removal of the removal conveyor directly on the foundation, and the U-shaped cage can be moved past this conveyor.

In noch weiterer Ausgestaltung des Erfindungsgegenstandes wird vorgeschlagen, dass im Bereich der Umlenkung der Kettenförderer eine trommelartige Verkleidung vorgesehen ist. Diese Verkleidung dient insbesondere der sauberen Führung der abzuschälenden flexiblen Unterlage.In yet another embodiment of the subject matter of the invention, it is proposed that a drum-like cladding be provided in the region of the deflection of the chain conveyor. This cladding is used in particular to cleanly guide the flexible base to be peeled off.

In noch weiterer Ausgestaltung hiervon wird vorgeschlagen, dass im Bereich der Umlenkung der Kettenförderer Führungen angeordnet sind. Zufolge Anordnung von Führungen ist eine sichere Umlenkung der Unterlagen gewährleistet, ohne dass das freie Ende der Unterlagen bei einem Hochschnellen eine Zerstörung der abzufördernden Spanplatte verursacht.In a further embodiment of this, it is proposed that guides are arranged in the region of the deflection of the chain conveyor. As a result of the arrangement of guides, the documents are deflected securely without the free end of the documents causing the chipboard to be removed from being destroyed in the event of a rush.

Als eine noch weitere Ausgestaltung des Erfindungsgegenstandes wird vorgeschlagen, dass mindestens das unterste Kettenfördererpaar im Bereich seiner rücklaufenden Trume mit einem Hilfsdeck versehen ist. Die Anordnung eines Hilfsdecks hat den beachtlichen Einfluss, dass die Kopfleisten der flexiblen Unterlagen wohlpositioniert von der Abfördervorrichtung übernommen werden können.As a still further embodiment of the subject matter of the invention, it is proposed that at least the lowest pair of chain conveyors be provided with an auxiliary deck in the area of its returning dreams. The arrangement of an auxiliary deck has the considerable influence that the headers of the flexible documents can be taken over by the removal device in a well-positioned position.

Zur wohlpositionierten Abförderung der von den flexiblen Unterlagen befreiten Spanplatten wird es als eine Ausgestaltung des Erfindungsgegenstandes angesehen, dass Quetschrollen mit einer Rollenbahn hinter der Trennstelle angeordnet sind. Durch Einsatz der mit regelbarer Geschwindigkeit umlaufenden Quetschrollen wird trotz diskontinuierlichem Entladen und Trennen ein kontinuierlicher Weitertransport der fertiggepressten Spanplatten ermöglicht.For the well-positioned removal of the chipboard freed from the flexible documents, it is regarded as an embodiment of the subject matter of the invention that pinch rollers with a roller conveyor are arranged behind the separation point. Thanks to the use of the pinch rollers rotating at an adjustable speed, the finished pressed chipboard can be transported continuously despite the discontinuous unloading and cutting.

Die Erfindung wird nachstehen anhand der Zeichnung näher erläutert.The invention is explained below with reference to the drawing.

Es zeigen:

  • Figur 1a, 1b, 1c, 1d, schematisch dargestellt den Entleer-, Trenn- und Abfördervorgang von fertiggepressten Spanplatten mit Unterlagen mit einem erfindungsgemässen Entleerkorb.
Show it:
  • Figure 1a, 1b, 1c, 1d, shown schematically the emptying, separating and removal process of pre-pressed chipboard with documents with an emptying basket according to the invention.

Eine Pressenentleereinrichtung bestehend aus einem Pressenentleerkorb 1, in dem Kettenfördererpaare 3, 4, 5 angeordnet sind, und bei der eine Abfördereinrichtung 6 vorgesehen ist, befindet sich zwischen einer schematisch dargestellten Dreietagenpresse 2 und einer Rollenbahn 8 mit mindestens einem Quetschrollenpaar 9.A press emptying device consisting of a press emptying basket 1, in which chain conveyor pairs 3, 4, 5 are arranged, and in which a discharge device 6 is provided, is located between a schematically illustrated three-day press 2 and a roller conveyor 8 with at least one pinch roller pair 9.

Der Pressenentleerkorb 1 besitzt weiterhin eine Einzugsvorrichtung 10, die nur in Figur 1 a dargestellt ist, um die in der Dreietagenpresse 2 vorhandenen fertiggepressten Spanplatten 11, einschliesslich flexibler Unterlagen 12 in den Einflussbereich der Kettenfördererpaare 3,4 und 5 zu bringen. Die Kettenfördererpaare 3, 4 und 5 besitzen Mitnehmer 13, mit denen sie hinter Kopfleisten 14 der flexiblen Unterlagen 12 fassen können. Damit werden aus der Dreietagenpresse 2 gleichzeitig alle mit Spanplatten 11 versehenen flexiblen Unterlagen 12 auf die Kettenfördererpaare 3, 4, 5 aufgefahren. Nachdem alle Kettenfördererpaare, die gleichzeitig als Etagen des Pressenentleerkorbs 1 anzusehen sind, mit flexiblen Unterlagen 12, die die Spanplatten 11 tragen belegt sind, wird anschliessend, wie in Figur 1 b dargestellt, ein Abschälvorgang und der gleichzeitige Rückführvorgang der flexiblen Unterlagen 12 durchgeführt.The press emptying basket 1 also has a feed device 10, which is only shown in FIG to bring the finished pressed chipboard 11, including flexible documents 12, into the area of influence of the chain conveyor pairs 3, 4 and 5. The chain conveyor pairs 3, 4 and 5 have drivers 13, with which they can grip behind headers 14 of the flexible documents 12. Thus, from the three-day press 2, all flexible documents 12 provided with particle boards 11 are simultaneously moved onto the chain conveyor pairs 3, 4, 5. After all pairs of chain conveyors, which are to be regarded as tiers of the press emptying basket 1 at the same time, are covered with flexible documents 12 which carry the chipboard 11, a peeling process and the simultaneous return process of the flexible documents 12 are then carried out, as shown in FIG. 1 b.

Das Kettenfördererpaar 5 das zusammen mit Decks 21 als Auflagen für die mit Spanplatten 11 versehenen flexiblen Unterlagen die unterste Etage des Pressenentleerkorbs 1 bildet, wird durch einen nicht dargestellten Motor in Gang gesetzt. Dabei werden die Kopfleisten 14 der flexiblen Unterlagen 12 von den an dem Kettenfördererpaar 5 angeordneten Mitnehmern 13 zum Antriebskettenräder 24 herumgeführt. Dabei ist der Bereich zwischen dem auf der linken und der rechten Seite des Pressenentleerkorbs 1 angeordneten Kettenförderer 5 mit einer trommelartigen Verkleidung 25 versehen, die zum einen die Verbindungs- und Antriebswelle der Antriebskettenräder 24 schützt, und zum anderen als Gleitunterlage für die flexible Unterlage 12 dient. Im Bereich der Umlenkung 26 werden somit zwangsläufig wie in Figur 1 b dargestellt, Spanplatte 11 und flexible Unterlage 12 voneinander getrennt. Die Spanplatte 11 wird von Quetschwalzen 9 übernommen und einer Rollenbahn 8 zur wieteren Bearbeitung zugeführt, die flexible Unterlage 12 wird mit den rücklaufenden Trummen 27 des Kettenfördererpaares 5 auf ein Hilfsdeck 15 aufgefahre und dort abgelegt; anschliessend wird auch der Antriebsmotor des Kettenfördererpaares 5 abgebremst.The chain conveyor pair 5 which, together with decks 21 as supports for the flexible documents provided with chipboard 11, forms the bottom floor of the press emptying basket 1 is set in motion by a motor, not shown. The headers 14 of the flexible documents 12 are guided from the drivers 13 arranged on the chain conveyor pair 5 to the drive sprockets 24. The area between the chain conveyor 5 arranged on the left and the right side of the press emptying basket 1 is provided with a drum-like cladding 25, which on the one hand protects the connecting and drive shaft of the drive sprockets 24, and on the other hand serves as a sliding support for the flexible support 12 . In the region of the deflection 26, chipboard 11 and flexible base 12 are thus necessarily separated from one another, as shown in FIG. 1b. The chipboard 11 is taken over by squeeze rollers 9 and fed to a roller conveyor 8 for further processing, the flexible base 12 is moved with the returning strands 27 of the chain conveyor pair 5 onto an auxiliary deck 15 and deposited there; then the drive motor of the chain conveyor pair 5 is braked.

Nachdem somit die unterste Etage des Pressenentleerkorbs entleert und gleichzeitig eine Trennung zwischen flexibler Unterlage 12 und Spanplatte 11 stattgefunden hat, wird der Pressenentleerkorb 1 um eine Etage abgesenkt, sodass nunmehr mit dem Kettenfördererpaar 4 die Entleerung und Trennung der nächsten Etage von Spanplatte 11 und flexibler Unterlage 12, wie oben für die unterste Etage beschrieben, durchgeführt werden kann.After the bottom floor of the press emptying basket has been emptied and at the same time there has been a separation between the flexible base 12 and the chipboard 11, the press emptying basket 1 is lowered by one level, so that the chain conveyor pair 4 now empties and separates the next floor from the chipboard 11 and the flexible base 12, as described above for the bottom floor.

Hierbei kann erfindungsgemäss anstelle eines zwischen Kettenfördererpaar 5 und Kettenfördererpaar 4 angeordneten Hilfsdecks 15 das Kettenfördererpaar 5 mit seinen Decks 21 selbst als Hilfsdeck zur Zwischenlagerung der abgeschälten flexiblen Unterlage 12 dienen.Here, according to the invention, instead of an auxiliary deck 15 arranged between the pair of chain conveyors 5 and the pair of chain conveyors 4, the pair of chain conveyors 5 with their decks 21 themselves can serve as an auxiliary deck for the intermediate storage of the peeled flexible base 12.

Um zu verhindern, dass die von der Spannplatte 11 befreite flexible Unterlage 12 mit dem nicht an Kopfleisten 14 geführten Ende 20 hochschnellt, sind Führungen 16 in jeder Etage vorgesehen.In order to prevent the flexible base 12 freed from the clamping plate 11 from springing up with the end 20 not guided on the head strips 14, guides 16 are provided on each floor.

Figur 1 c verdeutlicht, wie nach Entleerung des Pressenentleerkorbs 1 der Rücktransport der flexiblen Unterlagen 12 durchgeführt wird. Die unterste Etage ist mit der auf dem Hilfsdeck 15 aufliegenden flexiblen Unterlage 12 in den Wirkbereich der Abfördereinrichtung 6 gekommen. Die Abfördereinrichtung 6 wird über einen nicht dargestellten Antriebsmotor in Pfeilrichtung angetrieben und übernimmt so die flexiblen Unterlagen 12 die zunächst noch mit ihren Kopfleisten 14 von den Mitnehmern 13 der Kettenförderer 3, 4 und 5.hintergriffen sind. Wie in Figur 1 b noch schematisch dargestellt übergibt die Abfördereinrichtung 6 die flexible Unterlage 12 an ein weiteres.Rücktransportband, von dem aus die flexible Unterlage zu einer nicht dargestellten Schüttstation zum Wiederbelegen mit neuem Spanmaterial gebracht wird.FIG. 1 c illustrates how the flexible documents 12 are transported back after the press emptying basket 1 has been emptied. The bottom floor has come into the effective area of the removal device 6 with the flexible base 12 resting on the auxiliary deck 15. The discharge device 6 is driven by a drive motor, not shown, in the direction of the arrow and thus takes over the flexible documents 12, which are initially behind with their head strips 14 by the drivers 13 of the chain conveyors 3, 4 and 5. As shown schematically in FIG. 1b, the removal device 6 transfers the flexible base 12 to another return conveyor belt, from which the flexible base is brought to a pouring station, not shown, for re-loading with new chip material.

In Figur 1d ist ein Querschnitt entsprechend der Linie A-A durch den Pressenentleerkorb 1 dargestellt, in dem der Pressenentleerkorb 1 als nach unten offener U-förmiger Käfig 25 darge- stellt ist, in dem die Kettenfördererpaare 3, 4, 5 die die drei Etagen darstellen vorhanden sind und wobei deren rücklaufende Trume 27 von Hilfsdecks 15 im Abstand unterfangen sind. Gleichzeitig ist in diesem Schnitt die Abfördereinrichtung 6, die auf einem Sockel 17 angeordnet ist, der sich. : auf einem Fundament 18 abstützt, dargestellt. Bei taktweisem Abwärtsbewegen des Pressenentleerkorbs 1, kann die Abfördereinrichtung 6 in einem Schlitz 19 relativ zu dem abwärtsbewegten Pressenentleerkorb hochfahren und die einzelnen flexiblen Unterlagen 12 abfördern. Zweckmässiger Weise ist die Abfördereinrichtung 6 als Bandförderer ausgebildet. In Abhängigkeit der Höhe des Sockels 17 kann eine Abförderung der flexiblen Unterlagen 12 durch die Abfördereinrichtung bereits dann beginnen, wenn die erste flexible Unterlage auf dem Hilfsdeck 15 aufliegt. Die Abförderung geschieht dann hier nicht erst wie in Figur 1 dargestellt, wenn alle Etagen entleert sind, sondern lediglich um einen Takt gegenüber der Trennung verschoben. Der hierdurch erreichte Zeitgewinn ist offensichtlich.In Figure 1d a cross-section along line AA is represented by the Pressenentleerkorb 1, in which the Pressenentleerkorb 1 is shown as shaped U-downwardly open cage 25 in which the chain conveyor pairs 3, 4, 5, the three storey represent available are and where the returning dreams 27 of auxiliary decks 15 are undercut. At the same time in this section is the discharge device 6, which is arranged on a base 17, which is. : supported on a foundation 18, shown. When the press emptying basket 1 is moved downwards in cycles, the removal device 6 can move up in a slot 19 relative to the downward moving press emptying basket and convey the individual flexible documents 12 away. The removal device 6 is expediently designed as a belt conveyor. Depending on the height of the base 17, removal of the flexible documents 12 by the removal device can already begin when the first flexible base lies on the auxiliary deck 15. The removal does not take place here, as shown in FIG. 1, when all floors have been emptied, but only shifted by one cycle with respect to the separation. The time saved is obvious.

Das in Figur 1 c gestrichelt dargestellte Ende 20 einer flexiblen Unterlage 12, soll die Verhinderung des Hochschnellens dieses Endes durch die Führung 16 die oberhalb eines jeden Kettenfördererpaares angeordnet ist, verdeutlichen. Wie insbesondere aus Figur 1 d erkennbar, sind Decks 21 vorgesehen, die wie die Hilfsdecks 15 nur über eine bestimmte Breite des Pressenentleerkorbs 1 nach Innen ragen, sodass eindeutig der Schlitz 19 entsteht, in dem eine Relativbewegung zwischen der Abfördereinrichtung 6 und dem Pressenentleerkorb stattfinden kann. Wie der Figur 1 d weiterhin zu entnehmen ist, sind die Kettenfördererpaare 3, 4 und 5 ausserhalb der Decks 21 und Hilfsdecks 15 angeordnet. Aus Figur 1 d ist deutlich erkennbar, dass die Abfördereinrichtung 6 mit einer Umlenkung 23 vor den Umlenkungen der Kettenfördererpaare 3, 4 und 5 endet, da für den Antrieb dieser Kettenfördererpaare die Wellen über die volle Breite des Pressenentleerkorbs durchgeführt sind.The end 20 of a flexible base 12 shown in dashed lines in FIG. 1 c is intended to illustrate the prevention of this end from flipping up by the guide 16 which is arranged above each pair of chain conveyors. As can be seen in particular from FIG. 1 d, decks 21 are provided which, like the auxiliary decks 15, protrude inward only over a certain width of the press emptying basket 1, so that the slot 19 is clearly created, in which a relative movement between the removal device 6 and the press emptying basket can take place . As can also be seen from FIG. 1 d, the chain conveyor pairs 3, 4 and 5 are arranged outside the decks 21 and auxiliary decks 15. It can be clearly seen from FIG. 1 d that the discharge device 6 ends with a deflection 23 before the deflections of the chain conveyor pairs 3, 4 and 5, since the shafts are driven over the full width of the press emptying basket for driving these chain conveyor pairs.
