Description

Die Erfindung bezieht sich auf eine diskontinuierlich arbeitende Presse zum Zusammenballen lockeren Gutes, mit einem in einem Preßraum hin- und herbewegbaren Preßstempel, einer das Gut in den Preßraum fördernden Zufördereinrichtung und einem zur Erfassung des Gefüllzustandes vorgesehenen, oberhalb einer in einer der Seitenwandungen befindlichen Füllöffnung angeordneten Fühler, der mit einem sowohl das Zuführen als auch das Pressen des Gutes steuernden Organ zusammenwirkt.The invention relates to a discontinuously operating press for baling loose goods, with a press ram that can be moved back and forth in a press room, a feed device that conveys the goods into the press room, and a device provided for detecting the state of filling, arranged above a filling opening located in one of the side walls Sensor that interacts with an organ that controls both the feeding and the pressing of the goods.

Bei dem Zusammenballen lockerer Materialien wie beispielsweise Altpapierschnitzeln od. dgl. füllt sich der Preßraum einer Presse sehr rasch mit dem zu pressenden Gut, wobei dieses im Preßraum sehr locker zu liegen kommt, was zur Folge hat, daß je Preßvorgang nur ein geringes Volumen an Preßgut zustandekommt. Dieses ist besonders dann der Fall, wenn mit üblichen optischen Fühlern wie beispielsweise Lichtschranken od. dgl. ein bestimmter Füllungsgrad der Presse festgestellt und sodann der Preßvorgang automatisch oder von Hand aus eingeleitet wird.When agglomerating loose materials such as scrap paper or the like, the baling chamber of a press fills very quickly with the material to be pressed, which comes to rest very loosely in the baling chamber, which means that only a small volume of material to be pressed per pressing operation comes about. This is particularly the case when a certain degree of filling of the press is determined using conventional optical sensors such as light barriers or the like, and then the pressing process is initiated automatically or by hand.

Durch die britische Patentschrift 1 261 418 ist eine diskontinuierlich arbeitende Presse bekannt, bei der eine Lichtschranke die Aufschüttung des zusammenzuballenden lockeren Gutes bis in einen mit dem Preßraum verbundenen Einlaßschacht erfaßt. Da die Lichtschranke somit nur betätigt wird, wenn der Preßraum und der entsprechende Abschnitt des Einlaßschachtes locker mit dem zusammenzuballenden Material gefüllt sind, muß bis zum Erreichen eines bestimmten Ballenvolumens die Presse mehrmals hintereinander betätigt werden, was einen großen Aufwand sowohl an Zeit und als auch an Energie zur Folge hat.British Patent 1 261 418 discloses a discontinuously operating press in which a light barrier detects the filling of the loose material to be gathered up into an inlet shaft connected to the baling chamber. Since the light barrier is only actuated when the baling chamber and the corresponding section of the inlet shaft are loosely filled with the material to be aggregated, the press must be actuated several times in succession until a certain bale volume is reached, which is very time-consuming and time-consuming Energy.

Eine ähnliche Presse zeigt auch die deutsche Offenlegungsschrift 2201 327, bei der in der gleichen Weise oberhalb einer in einer der Seitenwandungen befindlichen Füllöffnung eine Lichtschranke angeordnet ist, die ein Absenken des Preßstempels bewirkt, sobald das in dem Preßraum gelangende Gut soweit aufgeschüttet ist, daß dieses Gut den Lichtstrahl unterbricht. Dieser Konstruktion haftet jedoch immer noch der Übelstand an, daß das zu pressende Papiermaterial, das im allgemeinen zuvor mittels Aktenvernichtern in Streifen oder auch Partikelchen zerschnitten wird, sich auch bei absolutem leerem Preßraum am Auge der Lichtquelle festsetzen kann, wodurch der Lichtstrahl auch dann unterbrochen wird, wenn die Preßkammer noch völlig leer ist.A similar press is also shown in German Offenlegungsschrift 2201 327, in which a light barrier is arranged in the same way above a filling opening located in one of the side walls, which causes the press ram to be lowered as soon as the goods entering the press room have been filled up to such an extent that the latter Well interrupts the light beam. This construction, however, still suffers from the disadvantage that the paper material to be pressed, which is generally cut into strips or particles beforehand by means of document shredders, can still adhere to the eye of the light source even with an absolutely empty press space, as a result of which the light beam is also interrupted when the bale chamber is still completely empty.

Gegenüber diesem zuvor aufgezeigten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, bei einer solchen Presse die Steuerung sowohl der mit einem Reißwerk ausgestatteten Zufördereinrichtung als auch des Preßstempels sicherer zu gestalten und somit beim Pressen einen höheren Wirkungsgrad zu erreichen.Compared to this prior art shown above, the object of the invention is to make the control of both the feed device equipped with a tearing mechanism and the press ram more reliable in such a press and thus to achieve a higher efficiency during pressing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Fühler oberhalb der schon zuvor erwähnten Seitenwandungen befindlichen Füllöffnung in den Preßraum hineinragt und als allseitig federnder Stab ausgebildet ist, der auf einen vorbestimmten erhöhten Staudruck des mittels der Zufördereinrichtung in den Preßraum eingebrachten Gutes anspricht und durch den Preßstempel elastisch aus dessen Bewegungsbahn herausschwenkbar ist.This object is achieved in that the sensor protrudes above the already mentioned side walls filling opening into the press chamber and is designed as a spring on all sides, which responds to a predetermined increased back pressure of the material introduced into the press chamber by means of the feed device and by the press ram can be elastically pivoted out of its movement path.

Bei dieser Gestaltung wird das Anwachsen des sich in dem Preßraum ansammelnden lockeren Gutes durch einen allseitig federnden mechanisch auf das Anwachsen des Gutes ansprechenden Stab überwacht, der bei einem vorbestimmten erhöhten Staudruck einen ihm zugeordneten Schalter umschaltet, wodurch die mit dem Reißwerk ausgerüstete Zufördereinrichtung stillgesetzt und der Preßstempel in Bewegung gesetzt wird, der das in dem Preßraum befindliche Gut zusammenpreßt. Da dieser federnde Stab infolge seiner eigenen elastischen Vorspannung erst auf einen vorbestimmten erhöhten Staudruck des sich in dem Preßraum ansammelnden Gutes anspricht, ist es unmöglich, daß einzelne in dem Preßraum umherirrende Teile oder Partikel des zu pressenden Gutes bereits einen ausreichend großen Druck auf den elastischen Stab ausüben und so etwa ein noch unerwünschtes Umschalten des zugeordneten Schalters bewirken. Dieser elastische Stab registriert somit mit absoluter Sicherheit im oberen Bereich der Preßkammer den jeweiligen Füllstand derselben auch dann, wenn es sich bei dem aus einem Aktenvernichter od. dgl. stammenden Gut um weiches und flexibles Streifenmaterial handelt. Durch die Elastizität des federnden Stabes wird auf das sich in der Preßkammer ansammelnde Gut aber auch ein gewisser Gegendruck ausgeübt, der ein Vorpressen des sich ansammelnden Gutes zur Folge hat, wobei dieser von dem federnden Stab ausgeübte Druck jedoch noch immer so gering zu bemessen ist, daß eine sichere Funktion auch eines der Presse vorgeschalteten Aktenvernichters gewährleistet und somit auch kein Rückstau, der die Funktion des Aktenvernichters zum Erliegen bringen würde, zu befürchten ist.In this design, the growth of the loose material accumulating in the baling chamber is monitored by a rod that responds mechanically to the growth of the material on all sides and that switches a switch assigned to it at a predetermined increased dynamic pressure, thereby stopping the feeder equipped with the tearing mechanism and the Press ram is set in motion, which compresses the material located in the press room. Since this resilient rod, due to its own elastic prestress, only responds to a predetermined increased dynamic pressure of the material accumulating in the press space, it is impossible for individual parts or particles of the material to be pressed that are straying in the press space to already have a sufficiently large pressure on the elastic rod exercise and thus cause an undesired switching of the assigned switch. This elastic rod thus registers with absolute certainty the respective filling level in the upper region of the press chamber even if the material originating from a document shredder or the like is soft and flexible strip material. Due to the elasticity of the resilient rod, however, a certain counter pressure is also exerted on the material accumulating in the bale chamber, which results in a pre-pressing of the accumulating material, although this pressure exerted by the resilient rod is still so small that that a safe function of a document shredder connected upstream of the press is guaranteed and therefore no backwater which would bring the function of the document shredder to a standstill must be feared.

Darüber hinaus läßt sich dieser federnde Stab beim Absenken des Preßstempels leicht aus dessen Bewegungsweg herausschwenken. Infolge seiner flexiblen Ausbildung kann der federnde Stab auch insofern unbegrenzt lang ausgebildet werden, als er sich problemlos in den verbleibenden Zwischenraum zwischen der Rückwand und dem Preßschemel abdrängen läßt.In addition, this resilient rod can be easily pivoted out of the path of movement when the ram is lowered. As a result of its flexible design, the resilient rod can also be made indefinitely long in that it can be easily pushed into the remaining space between the rear wall and the press stool.

Eine beispielsweise Ausführungsform dieser Erfindung ist aus der folgenden Beschreibung einer in einer Zeichnung in der Seitenansicht und teilweise geschnitten dargestellten Presse zu entnehmen.An exemplary embodiment of this invention is evident from the following description of a press shown in a drawing in side view and partly in section remove.

Ein durch einen Motor 16 antreibbares Reißwerk 1 zerkleinert einerseits das zu pressende Papier in schmale Streifen oder Schnitzel und fördert andererseits das zerkleinerte Papier in einen Preßraum 2, in dem ein Preßstempel 3 hin-und herbewegbar ist. Der Preßraum 2 wird in seinem unteren Bereich von einem Preßkorb 4 gebildet, der auf Rollen 5 aus der Presse ausfahrbar ist. Oberhalb des Preßkorbes 4 ist der Preßraum 2 durch Seitenwandungen 6 begrenzt. In einer der Seitenwandungen 6 ist eine Füllöffnung 7 vorgesehen, in die ein vom Reißwerk 1 kommender Einlaßschacht 8 einmündet.A tearing mechanism 1 which can be driven by a motor 16, on the one hand, shreds the paper to be pressed into narrow strips or chips and, on the other hand, conveys the shredded paper into a press chamber 2, in which a press ram 3 can be moved back and forth. The press chamber 2 is formed in its lower region by a press basket 4 which can be extended from the press on rollers 5. Above the press basket 4, the press chamber 2 is delimited by side walls 6. In one of the side walls 6, a filling opening 7 is provided, into which an inlet shaft 8 coming from the tearing mechanism 1 opens.

In dem oberhalb der Füllöffnung 7 befindlichen Bereich des Preßraumes 2 ist ein als federnder Stab ausgebildeter Druckfühler 9 vorgesehen, der in die Bewegungsbahn des Preßstempels 3 ragt und aus derselben durch den sich abwärts bewegenden Preßstempel 3 elastisch herausschwenkbar ist. Der stabförmige Druckfühler 9 betätigt bei eingeschwenkter Lage einen nicht besonders dargestellten Schalter, durch welchen bei Überschreiten eines vorbestimmten Staudrucks an dem stabförmigen Druckfühler 9 und bei entsprechender Verbiegung desselben das Reißwerk 1 ausgeschaltet wird.In the area of the press chamber 2 located above the filling opening 7, a pressure sensor 9 designed as a resilient rod is provided, which projects into the movement path of the press ram 3 and can be elastically pivoted out of it by the downwardly moving press ram 3. When the position is swiveled in, the rod-shaped pressure sensor 9 actuates a switch (not shown in particular), by means of which the tear mechanism 1 is switched off when a predetermined dynamic pressure at the rod-shaped pressure sensor 9 is exceeded and when the latter is bent accordingly.

Ist die Presse mit einer automatischen Steuervorrichtung versehen, so kann durch den von dem Druckfühler 9 betätigten Schalter nach Abschalten des Reißwerkes 1 auch der nicht dargestellte Antrieb des Preßstempels 3 eingeschaltet und damit der eigentliche Preßvorgang eingeleitet werden.If the press is provided with an automatic control device, then the drive of the press ram 3 (not shown) can also be switched on by the switch actuated by the pressure sensor 9 after the tear-off mechanism 1 has been switched off, and the actual pressing process can thus be initiated.

Die vorstehend beschriebenen Bauelemente werden von Tragsäulen 14 getragen, die an einer Grundplatte 15 angeordnet sind.The components described above are supported by support columns 14 which are arranged on a base plate 15.

Bei Benutzung der Presse wird das zu pressende Papier durch das Reißwerk 1 in schmale Streifen oder Schnitzel zerteilt und durch den Einlaßschacht 8 und die Füllöffnung 7 in den Preßraum 2 hineingefördert. Die Förderung hält an, bis im Preßraum 2 das Preßgut durch das die Zuförderung bewirkende Reißwerk 1 so stark vorverdichtet ist, daß infolge des Staudrucks der als federnder Stab ausgebildete Druckfühler 9 elastisch verbogen und damit durch den nicht dargestellten Schalter das Reißwerk 1 außer Betrieb gesetzt und der Preßstempelantrieb eingeschaltet wird. Erst jetzt erfolgt die erste eigentliche Pressung der Papierschnitzel durch den herabgehenden Preßstempel 3, der in seiner unteren Preßstellung einige Zeit verharrt, um bei seinem anschließenden Rückhub ein Wiederausdehnen des gepreßten Materials zu verringern. Der Druckfühler 9 wird beim Herabgehen des Preßstempels 3 durch denselben aus dessen Bewegungsbahn elastisch herausgeschwenkt und verbleibt während des Preßvorganges in dem Zwischenraum zwischen dem Preßstempe) 3 bzw. den die Seitenflächen naCll hinten fortsetzenden Abdeckplatten und den Seitenwandungen 6 des Preßraumes. Anschließend wird der Preßstempel 3 in seine Ausgangsstellung zurückbewegt, wobei der Druckfühler 9 wieder in seine Ausgangsstellung zurückkehrt, sobald der Preßstempel 3 in seiner oberen Endstellung zurückgekehrt ist. Nun kann das Reißwerk 1 wieder in Betrieb gesetzt werden, um wieder so lange weitere lockere Papierschnitzel oder -streifen auf die Oberfläche des bereits gepreßten Ballen zu fördern, bis durch den sich wiederum neu aufbauenden Staudruck der Druckfühler 9 erneut betätigt wird. Daraufhin wiederholt sich der vorstehend geschilderte Ablauf des Preßvorganges. Das Füllen des noch freien Preßraumes erfolgt dabei so oft, bis sich der Preßstempel 3 in seiner unteren Preßstellung nurmehr knapp unter dem oberen Rand des Preßkorbes 4 befindet. Ist der Preßstempel 3 dann in seine Ausgangslage zurückgekehrt, so wird der Preßkopf 4 auf seinen Rollen 5 aus der Presse herausgefahren, der gepreßte Ballen dem Preßkorb 4 entnommen und derselbe sodann wieder in die Presse eingefahren.

When using the press, the paper to be pressed is divided into narrow strips or chips by the tearing mechanism 1 and conveyed through the inlet shaft 8 and the filling opening 7 into the press chamber 2. The funding continues until the material to be pressed is pre-compressed to such an extent in the pressing chamber 2 that the pressure sensor 9, which is designed as a resilient rod, is elastically bent due to the dynamic pressure and, as a result, the tearing machine 1 is put out of operation by the switch (not shown) and the ram drive is switched on. Only now does the first actual pressing of the shredded paper take place by the descending press ram 3, which remains in its lower press position for some time in order to reduce re-expansion of the pressed material on its subsequent return stroke. The pressure sensor 9 is pivoted elastically out of its movement path when the press ram 3 goes down and remains during the pressing process in the space between the press die 3 or the cover plates continuing the side surfaces and the side walls 6 of the press room. Then the press ram 3 is moved back into its starting position, the pressure sensor 9 returning to its starting position as soon as the press ram 3 has returned to its upper end position. Now the tearing unit 1 can be put into operation again in order to convey further loose paper chips or strips onto the surface of the already pressed bale until the pressure sensor 9 is actuated again by the back pressure which builds up again. The above-described sequence of the pressing process is then repeated. The filling of the still free pressing space takes place until the press ram 3 in its lower pressing position is only just below the upper edge of the pressing basket 4. When the press ram 3 has then returned to its initial position, the press head 4 is moved out of the press on its rollers 5, the pressed bale is removed from the press basket 4 and the same is then retracted into the press.
