Abstract (en)

The assembly (10) to position and/or transfer a roller (14) at a papermaking machine has at least one lifting system (20) at the machine frame (18), linked to the machine frame (18) at one side and the bearing pedestal (22) of the roller (14) at the other side. The lifting system (20) is fitted with a sliding movement across the load-bearing direction, and the roller axis, at the machine frame (18) and bearing pedestal (22). Sliding couplings (24,26) are at the machine frame (18) and bearing pedestal (22), as linkage points for the lifting system (20). The lifting system (20) has at least one lifting cylinder (20'). An upper linkage point (28), between the lifting system (20) and the machine frame (18), is set to reduce the horizontal movement of the roller (14) to a min. through distortion of the machine frame (18) when under a load. The lifting system (20) and/or the bearing pedestal (22) at the roller (14) are additionally linked at the sides to the machine frame (18) by at least one setting cylinder (32). For a blanket change, the lifting system (20) and the setting cylinder are controlled and set so that the roller (14) only has a vertical movement, and the setting cylinder (32) is not charged for a blanket change. The lifting system (20) and the setting cylinder (32) are in a combination for control so that the roller (14) can be given a movement away from the vertical, and the setting cylinder (32) can move the roller (14) horizontally independently of the lifting system (20). The setting cylinder (32) gives the roller (14) a side movement, when it has been lifted into the upper position and locked in place. A lifting system (20) is for each bearing pedestal (22) at both ends of the roller (14), and a side movement can be given to both ends of the roller (14). The lifting system (20) is brought to the upper roller (14) of a web press station with two press rollers (14,16). A mechanical lock is at the lifting system (20) and the setting cylinder (32), to secure the weight of the lifted and/or deflected roller (14) for safety in the event of a cable break.

Eine Vorrichtung 10 zur Positionierung und/oder Verlagerung einer in einer Papiermaschine eingesetzten Walze 14 umfaßt wenigstens eine an einem Maschinengestell 18 abgestützte Hubeinrichtung 20, die einerseits an dem Maschinengestell 18 und andererseits an einem der Walze 14 zugeordneten Lagerbock 22 angelenkt ist. Die Hubeinrichtung 20 ist sowohl an dem Maschinengestell 18 als auch an dem der Walze 14 zugeordneten Lagerbock 22 jeweils allgemein quer zur Lastrichtung und Walzenachse verschiebbar befestigt. <IMAGE>
