Description

Die Erfindung betrifft ein Walzenwechselwerkzeug mit einer über einen Haken an einer Walzenmaschine abstützbaren Ausbauvorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a roll change tool with a supportable via a hook on a roll machine expansion device according to the preamble of patent claim 1.

Aus der DE 196 33 668 C1 ist ein derartiges Walzenwechselwerkzeug bekannt, das die jeweils zu wechselnde Walze auf einer Führungsbahn aus dem Walzenstapel entfernt. Dazu muß die Walze auf der Führungsbahn in eine Walzenaufnahme hineinrollen. Eine direkte Bewegungssteuerung der Walze auf der Führungsbahn ist hierbei nicht möglich, weil die Bewegung durch die Schwerkraftwirkung verursacht wird. Darüber hinaus bedingt die Führungsbahn einen langen Hebel, damit die Walze aus der Walzenebene des Walzenstapels herausbewegt wird. Nur in Verbindung mit einem Gegengewicht an der Walzenaufnahme kann sichergestellt werden, daß in allen Fällen der Schwerpunkt des Walzenwechselwerkzeugs unterhalb der Hubvorrichtungs-Halterung liegt.From DE 196 33 668 C1, such a roll change tool is known which removes the respective roll to be changed on a guide track from the roll stack. For this purpose, the roller must roll on the guideway in a roller mount. A direct movement control of the roller on the guideway is not possible here, because the movement is caused by the force of gravity. In addition, the guideway requires a long lever, so that the roller is moved out of the rolling plane of the roller stack. Only in conjunction with a counterweight on the roll holder can be ensured that in all cases the center of gravity of the roll change tool is below the Hubvorrichtungs holder.

Dadurch hat der Hebel immer eine Ausrichtung im wesentlichen in horizontaler Richtung, wenn das Walzenwechselwerkzeug am Walzenwechselkran hängt. Ein solches Walzenwechselwerkzeug hat den Nachteil, daß ein großer Hebelarm erforderlich ist, der nicht nur mit einem Gegengewicht belastet ist, sondern durch eine Rollbewegung der Walze auch eine zusätzliche Belastung erfährt.As a result, the lever always has an orientation substantially in the horizontal direction when the roll change tool depends on the roll changing crane. Such a roll change tool has the disadvantage that a large lever arm is required, which is not only loaded with a counterweight, but also undergoes an additional load by a rolling movement of the roller.

Aus DE 196 33 669 C1 ist ein Walzenwechselwerkzeug mit zwei einander gegenüberliegenden Walzenaufnahmen und einem Haltearm bekannt. Der Haltearm steht dabei seitlich zu einer Ebene, die durch die Mittelachsen der Walzenaufnahmen gebildet ist, vor. Das Walzenwechselwerkzeug besitzt einen Aufhängepunkt, an dem ein Kranhaken angreifen kann.From DE 196 33 669 C1 a roll change tool with two opposing roll receptacles and a holding arm is known. The holding arm stands laterally to a plane which is formed by the central axes of the roller mounts before. The roll change tool has a suspension point on which a crane hook can attack.

Aus DE 198 56 517 A1 ist eine Vorrichtung zum Walzenaustausch bei einem Kalander bekannt, die eine Transportvorrichtung für den An- und Abtransport der Walzen aufweist. Eine von der Transportvorrichtung mitnehmbare Wechselvorrichtung weist je eine Aufnahmevorrichtung für eine erste und eine zweite Walze auf. Eine Transportvorrichtung in der Form eines Krans besitzt einen Haken, an welchem eine Wechselvorrichtung mit einem Zapfen hängt.From DE 198 56 517 A1 discloses a device for roller replacement in a calender is known which has a transport device for the supply and removal of the rollers. A removable device which can be entrained by the transport device has in each case a receiving device for a first and a second roller. A transport device in the form of a crane has a hook on which a changing device hangs with a pin.

Aufgabe der Erfindung ist es daher, ein Walzenwechselwerkzeug nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, das einen einfachen und schnellen Walzenwechsel ermöglicht.The object of the invention is therefore to provide a roll change tool according to the preamble of patent claim 1, which allows a simple and fast roll change.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.This object is solved by the features of the characterizing part of patent claim 1.

Hierdurch wird ein Walzenwechselwerkzeug geschaffen, das eine zu wechselnde Walze mittels Laufkatzen einfach und platzsparend aus dem Walzenstapel entfernt. Dabei greift das Walzenwechselwerkzeug von oben an der auszuwechselnden Walze an. Die Walze wird also hängend aufgenommen. Ein weiterer Vorteil liegt darin, daß dadurch auch der seitliche Zugang zur Walzenmaschine deutlich verbessert wird. Die Bewegungssteuerung der Walze ist zudem direkt. Darüber hinaus ermöglicht das Walzenwechselwerkzeug einen zielgerichteten schnellen Walzenwechsel, da das Walzenwechselwerkzeug beim Einhängen an der Walzenmaschine über den Schaftfortsatz gelenkt wird. Die Ausbauvorrichtung ist ferner kompakt.As a result, a roll-changing tool is provided which removes a roll to be changed by means of trolleys in a simple and space-saving manner from the roll stack. In this case, the roll change tool engages from above on the roller to be replaced. The roller is thus added hanging. Another advantage is that thereby also the lateral access to the rolling machine is significantly improved. The movement control of the roller is also direct. In addition, the roll change tool allows a targeted rapid roll change, since the roll change tool is steered when hanging on the roll machine on the shaft extension. The expansion device is also compact.
