Abstract
An apparatus used on a spinning room preparation machine, which is specially a carding mechine, a draw frame, a combing machine or a bobbiner and has a drafting mechanism for drafting strand fibre materials, has a pair of scanning rollers pressed against one another for continuously recording the cross-sectional area and/or fibre amount of at least one fibre strip, wherein one of the rollers is immovable and the other roller is arranged that it can deviate from the immovable roller. The apparatus has a non-contact spacing sensor for measuring the spacing from the corresponding surface (sensedsurface). In order to arrange the spacing sensor in simple modus specially in limited spacing and improve the connection between the spacing sensor and the sensed surface, the spacing sensor is integrated to the holding element of the roller.
Description
Technical field:
The present invention relates to be used in spinning room preparation machine, carding machine particularly, drawing frame, device on combing machine or the Speed frames, these preparation facility have and are used for the drafter of drawing-off thigh shape fibrous material, this device is used for writing down continuously the cross-sectional area and/or the fibre weight of at least one ribbon, it has, and to be arranged to the measurement roller that presses mutually right, one of them roller is arranged to not removable and another roller is arranged to and can removes at never removable roller place, and has the contactless range sensor of the spacing that is used for measuring distance corresponding component surface (sensitive surface).
Background technology:
Usually to measure the rugosity of ribbon in the production practices, particularly for the neat and well spaced purpose that is incorporated into the one or more ribbons in the spinning room preparation machine.Also need to carry out this type of measures to be used for the quality control of the drafted material that comes out in the exit of machine.Except that described quality control, if predetermined mass change limit is exceeded and the high-quality product of therefore can't reentrying, the measured value relevant with the density of ribbon or rugosity also is used to closing machine.
In the known device with drafter (WO91/16595A), ribbon is directed into immovable roller and can be pressed against movably between the roller (traction roller and induction roller) on it.This traction roller and induction roller are fixed on the axle.This traction roller is installed in rotation in the clutch shaft bearing case by roller shaft.This clutch shaft bearing case immovably is arranged in the drawing frame.Described induction roller is installed in rotation in second bearing housing by roller shaft.This second bearing housing is being arranged in the drawing frame along the mode that direction A takes place to be offset.This skew produces the active force with the compression spring that contends with.This compression spring constriction answers roller against traction roller and rest on immovable parts of drawing frame.One measures plate is disposed on second bearing housing.This measurement plate has guaranteed that displacement transducer has reference planes accurately.Spacing B between this displacement transducer recorded bit displacement sensor and the measurement plate.The variation of spacing B is sent to the ribbon monitor by the variation of displacement transducer by voltage.This displacement transducer correspondingly is used as signal converter.The spacing B that is used as measuring distance is very little usually, promptly a few tenths of millimeter.Even the minimum change of the spacing between traction roller and the induction roller also can be noted by displacement transducer.This displacement transducer is fixed on immovable parts of drawing frame, and the compression spring is against thereon.As a result, these immovable parts and displacement transducer be disposed in second bearing housing clearance spaces away from roller nip one side at regular intervals in.A shortcoming just is to require sizable spacing in the space that is restricted.In addition, the arrangement that is used for the installation position displacement sensor is that the cost of mounting means is disadvantageous.At last, the installation of displacement transducer on immovable parts needs special adjusting or setting program.
Summary of the invention:
Therefore, the problem that the present invention is directed to provides a kind of device of describing at this paper the beginning part, it has avoided above-mentioned shortcoming, especially can particularly arrange range sensor in limited space in simple mode, and can improve the interrelational form of range sensor and sensitive surface.
This problem is solved by the described feature of claim 1.
By holding element, and so locate and the opposed sensitive surface of this range sensor, can obtain to save the arrangement in space in conjunction with range sensor and other roller.Range sensor can also while simplified structure and installation with favourable combination the between existing other roller holding element.The change of spacing is favourable for measuring the ribbon rugosity between the holding element.Range sensor mechanically is incorporated into the adjusting program of having simplified range sensor in the holding element in graceful especially mode.The arrangement simple in structure of this range sensor has been saved the space.Therefore this range sensor correspondingly makes up with the holding element of spinning room preparation machine, and this combination just can have a plurality of functions simultaneously like this.
Claim 2-75 has comprised useful improvement of the present invention.
