Problems solved by technology

One disadvantage is that it requires considerable spacing in a constrained space
Furthermore, the arrangement for mounting the displacement sensor, ie the outlay for the mounting, is disadvantageous
Finally, the installation of displacement transducers on non-movable parts requires special adjustment or setup procedures

Embodiment Construction

[0016] Such as figure 1 As shown, a draw frame 1 (for example a Trützschler TD03 type draw frame) has a drafting unit 2 , upstream of which is an inlet 3 of the drafting unit 2 and downstream of which is an outlet 4 . The sliver 5 from the can (not shown) is drawn by the take-off roller into the sliver guide 6 and conveyed past the measuring element (distance sensor 9). The drafting mechanism 2 is designed as a 4-up and 3-down drafting mechanism. That is, it includes three bottom rollers I, II, III (output bottom roller I, middle bottom roller II, input bottom roller III) and four top rollers 11, 12, 13, 14. For the fiber strip combined body 5 formed by a plurality of fiber strips 5 IV The drafting is carried out by the drafting mechanism 2. The drafting process includes pre-drafting and main drafting. The roller pairs 14 / III and 13 / II constitute the pre-drafting zone and the roller pairs 13 / II and 11, 12 / I constitute the main drafting zone. Fiber strip merged body 5 I D...

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: [0001] The invention relates to a device for use on a spinning room preparation machine, in particular a card, draw frame, comber or roving frame, which has a drafting mechanism for drawing strand-like fiber material, the device for Continuously record the cross-sectional area and / or fiber quantity of at least one fiber strip having a pair of measuring rollers arranged to press against each other, one roller being arranged immovably and the other roller being arranged movable from the immovable roller and has a non-contact distance sensor for measuring the distance from the corresponding component surface (sensing surface). Background technique: [0002] It is common in production practice to measure the thickness of the fiber sliver, in particular for the purpose of leveling the introduction of one or more fiber slivers into the spinning room preparation machine. Such measurements are also required at the exit of the machine for quality control of the draw...
