Embodiment Construction

[0027] exist figure 1 shows a position-controlled drive 7 with a valve 6 according to the prior art. Installed in the position control drive housing 9: a push rod 10 protruding from the position control drive housing 9 and supported in the position control drive housing in an axially movable manner, for axially moving the push rod 10 The main shaft driving device 11, the driving motor 12, the electronic control device 13 and the encoding device 14 for accurately determining the position of the push rod 10 are provided.

[0028] In order to fit all these components in the housing 9, the construction of the housing 9 must be very expensive. Furthermore, the housing 9 must be detachably closed by means of several screw connections in order to open and close it for maintenance purposes.

[0029] The electronic control units 13 of the individual position-controlled drives 7 are connected to one another via a series circuit, so that the signal of the lateral adjustment device 1 mu...

Abstract

The invention relates to a position-controlled drive for driving a valve (6), in particular for driving a dilution water valve such as that used in fiber web manufacturing machines, the position-controlled drive comprising a drive housing body (9), a push rod (10) protruding from the drive device housing (9) and axially movably supported in the drive device housing, for axially moving the push rod (10) ) spindle drive device (11) and drive motor (12), wherein the drive motor (12) is a stepper motor (17) or a synchronous motor, which can be arranged outside the drive device housing (9) A control unit is used to adjust the drive motor, wherein the moving stroke of the push rod (10) is determined by counting the integral steps of the stepper motor (17).

Description

technical field [0001] The invention relates to a position-controlled drive device and a position-controlled drive system for driving valves, in particular for driving dilution water valves such as those used in fiber web manufacturing machines. Background technique [0002] It is known to have a fiber web manufacturing machine with a headbox to which a material suspension is supplied via a plurality of conduits from a distributor, wherein the individual volume flows are regulated by several adjustable valves. [0003] It is also known to implement a further zoned supply of material in the headbox for adjusting the basis weight (basis weight) of the paper. Such a mixing device is known, for example, from patent document DE4019593. A mixing device is described here which mixes a plurality of volume partial flows to produce a constant mixed volume flow. To this end, the individual volume fractions are conducted into the mixer and are regulated interdependently by means of a ...
