Embodiment Construction

[0033] figure 1 A hydraulic actuator device 10 according to the invention is schematically shown associated with a handling device of a web roll and / or take-up shaft of a fiber web machine. exist figure 1 In the embodiment of , the fiber web machine is the winding section 1.10 of a slitter-winder for winding so-called consumer rolls 1.14. Here, there is a hydraulic actuator device 10 arranged in association with the pinch bar 1.12 of the winding section 1.10, by means of which hydraulic actuator device 10 the coil set to be wound can be supported and / or loaded from one direction. The winding section 1.10 here is a so-called carrier roll winder, and the roll group formed from the partial web W is wound up supported by a carrier roll 1.16 and a belt roll 1.18. Of course, these belt rolls could be another backup roll.

[0034] exist figure 1 In an embodiment of the present invention, the hydraulic actuator device 10 used as the power unit for unloading or loading the coil gro...

Abstract

The present invention relates to a hydraulic actuator arrangement (10), comprising a hydraulic actuator (12, 15, 55, 56) and a control device (14) to control the flow of hydraulic medium to and / or from the hydraulic actuator. The hydraulic actuator arrangement (10) comprises an energy accumulator unit (26, 27) connected to the hydraulic medium discharged from the hydraulic actuator. The invention also relates to hydraulic treatment arrangement for fiber web machine web rolls and / or reeling shafts, which comprises at least one machine element (1.10) driven by the hydraulic actuator arrangement (10).

Description

technical field [0001] The object of the invention is a hydraulic actuator arrangement according to the preamble of claim 1 , comprising a hydraulic actuator and control means for controlling the flow of hydraulic medium to and / or from the hydraulic actuator. [0002] Another object of the invention is a handling device for web rolls and / or take-up shafts of a fiber web machine according to the preamble of claim 8, comprising at least a machine element. Background technique [0003] Fiber webs are processed in many different ways using various equipment of fiber web machines. Fiber web machines and their equipment require high operating precision and they are bulky. Therefore, the power supply equipment used must be very precise, but at the same time the power requirements can be very high. The power required especially when handling web rolls and take-up shafts (drums, tambour) can be quite high. Therefore, hydraulic actuators are commonly used as power supply equipment...
