Description

Die Erfindung betrifft eine Vorrichtung zum Aufreißen von Säcken gemäß des Oberbegriffes des Patentanspruches 1.The invention relates to a device for tearing bags according to the The preamble of claim 1.

Eine derartige Vorrichtung ist beispielsweise durch die EP 0 686 562 A1 bekannt. Diese Vorrichtung weist einen Rahmen auf, in dem die Aufreißtrommel, die mit Aufreißelementen besetzt ist, drehbar angeordnet ist. Diesen Aufreißelementen sind Gegenhalteelemente einer Gegenhaltevorrichtung zugeordnet, die mittels eines Hydraulikzylinders gegen die Trommel gedrückt werden. Die Gegenhalteelemente und die Aufreißtrommel bilden einen nach oben sich öffnenden Keil. Wenn die Gegenhalteelemente sehr dicht an der Trommel anliegen, kommt es im unteren Bereich aufgrund der Reibung zu dem Effekt, daß die Gegenhalteelemente durch die Aufreißtrommel mit den Säcken beziehungsweise mit dem sich in den Säcken befindlichen Material sehr stark gegen die Trommel gezogen werden, so daß es sogar teilweise zu einer Selbsthemmung kommt und die Drehbewegung blockiert wird.Such a device is known for example from EP 0 686 562 A1. This Device has a frame in which the tear drum, which with Tear elements is occupied, is rotatably arranged. These tear elements are Counter holding elements assigned to a counter holding device, which by means of a Hydraulic cylinders are pressed against the drum. The counterhold elements and the ripping drum form a wedge that opens upwards. If the Counter-holding elements lie very close to the drum, it occurs in the lower one Area due to the friction to the effect that the counter holding elements by the Tear-off drum with the sacks or with the ones in the sacks material is pulled very strongly against the drum, so that it even partially self-locking occurs and the rotary movement is blocked.

Der Erfindung liegt die Aufgabe zugrunde, auf einfache Weise sicher zu stellen, daß die Gefahr der Selbsthemmung auf einfache Weise verhindert wird.The invention has for its object to ensure in a simple manner that the The risk of self-locking is prevented in a simple manner.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Infolge dieser Maßnahme kann die Stellung des gekrümmten Bereiches der Gegenhaltevorrichtung zu der Aufreißtrommel verändert werden, so daß die Stellung der Gegenhalteelemente der Gegenhaltevorrichtung zu der Aufreißtrommel verändert wird. Somit kann der Spalt beziehungsweise der Öffnungswinkel zwischen dem Gegenhalteelement und der Trommel verändert werden, indem die oberen zu den unteren Gliedern der Gegenhalteelemente der Gegenhaltevorrichtung in ihrer Stellung zueinander verändert werden. Eine optimale Anpassung läßt sich dadurch erreichen, daß zumindest der untere Bereich der Gegenhalteelemente als Gliederkette ausgebildet ist, wobei zwischen den einzelnen Gliedern Koppel- und/oder Stellelemente in Form von Hydraulikzylindern oder anderen Stellmotoren angeordnet sind. Es ist auch möglich, anstelle aktiver Stellelemente, passive Koppelelemente, wie beispielsweise einstellbare Federelemente oder Gegengewichte einzusetzen. This object is achieved by the characterizing features of Claim 1 solved. As a result of this measure, the position of the curved Area of the counter-holding device to the tear drum are changed so that the position of the counter-holding elements of the counter-holding device in relation to the ripping drum is changed. Thus, the gap or the opening angle between the counter-holding element and the drum can be changed from the top to the lower links of the counter-holding elements of the counter-holding device in their position to be changed to each other. An optimal adaptation can be achieved that at least the lower area of the counter-holding elements as a link chain is formed, with coupling and / or adjusting elements between the individual links are arranged in the form of hydraulic cylinders or other servomotors. It is also possible, instead of active control elements, passive coupling elements, such as adjustable spring elements or counterweights.

Es hat sich gezeigt, daß es jedoch in vielen Fällen ausreicht, wenn das Gegenhalteelement in zwei Gliedern unterteilt ist, die mit einem Gelenk verbunden sind und wobei in dem Gelenkbereich zwischen den beiden Gliedern eine Koppel- und/oder Stellvorrichtung angeordnet ist. Hierbei ist vorteilhaft, wenn das die beiden Glieder verbindende Gelenk sich jeweils im Übergangsbereich zwischen dem gradlinigen und gekrümmt verlaufenden Bereich befindet. In vorteilhafter Weise liegen die die beiden Glieder verbindenden Gelenke etwa auf der Höhe der Aufreißtrommel.It has been shown that in many cases it is sufficient if that Counter-holding element is divided into two links that are connected with a joint and wherein in the joint area between the two links a coupling and / or Actuating device is arranged. It is advantageous if this is the two links connecting joint each in the transition area between the straight and curved area is located. The two are advantageously located Links connecting joints at about the level of the ripping drum.

Eine vorteilhafte Anordnung der Stellvorrichtung ergibt sich dadurch, daß sie auf der der Trommel abgewandten Seite des Gegenhalteelementes angeordnet ist.An advantageous arrangement of the actuator results from the fact that it on the the side of the counter-holding element facing away from the drum.

Weitere Einzelheiten der Erfindung sind der Beispielsbeschreibung und den Zeichnungen zu entnehmen.Further details of the invention are the example description and the Take drawings.
