Apparatus on a drafting system of a spinning room machine, for weighting drafting system rollers
First Claim
1. An apparatus on a drafting system of a spinning room machine, for weighting a drafting system roller, the apparatus comprising:
- at least one pressure-medium system including;
a pressure-medium cylinder;
a piston acted upon by a pressure medium and axially movable inside the cylinder; and
a piston rod connected to the piston and passing through an end of the cylinder to apply weighting to the roller,at least one inductive displacement sensor disposed within the pressure-medium system and configured to detect movements of the piston in two directions and produce a corresponding output signal;
an evaluation device coupled to the output signal and producing a displacement signal corresponding to a measured displacement of the piston; and
an electronic control and regulation device coupled to the at least one inductive displacement sensor and configured to receive the displacement signal, wherein the electronic control and regulation device is adapted to compare the displacement signal to stored predetermined maximum and minimum values relating to allowable lap formation on the roller and wear to the roller, respectively.

Abstract
In an apparatus on a drafting system of a spinning room machine, especially a draw frame, carding machine, combing machine or the like, for weighting the drafting system rollers, at least one pressure-medium cylinder with a piston is acted upon by pressure medium and is arranged so as to be axially movable inside a cylinder housing. A piston rod extends from piston passing through at least one cylinder cover that defines the cylinder housing at the end. In order to improve the apparatus, for determining the position of the piston with the piston rod, at least one inductive displacement sensor is integrated into the pressure-medium system, and the inductive displacement sensor is connected to an evaluation device.

22. A method for weighting a drafting system roller of a spinning room machine, comprising:
-
weighting said roller with a pressure-medium system comprising a pressure-medium cylinder and a piston which is acted upon by a pressure medium, wherein the piston is arranged so as to be axially movable inside the cylinder and wherein a piston rod connected to the piston passes through an end of the cylinder to apply weighting to the roller; detecting movements of the piston in two directions with at least one inductive displacement sensor disposed within the pressure-medium system; producing a displacement signal corresponding to a measured displacement of the piston by an evaluation device coupled to the output signal; receiving the displacement signal by an electronic control and regulation device coupled to the at least one inductive displacement sensor; and comparing the displacement signal, by the electronic control and regulation device, to stored predetermined maximum and minimum values relating to allowable lap formation on the roller and wear to the roller, respectively. - View Dependent Claims (23, 24)
