    专利说明:

    The invention relates to a drafting system for a spinning preparation machine, in particular for a route, carding or comber, according to the preamble of claim 1.
    In a known device (DE 10 347 192 A) a cleaning rod (cleaning strip) is present, which is mounted with its ends in each case on a push rod and the push rod has a bearing element for the cleaning rod. The cleaning rod rests on the top roller, which it constantly cleans during operation. Due to the rotation of the top roller and the constantly changing contact with the lateral surface of the upper roller, the touching, immovable area of the stationary cleaning rod is subject to a constant wear attack. The cleaning rod is installed in only one position in the machine, so that there is only one wear edge on the circumference of the cleaning body. This substantially linear or line-like contact is widened with increasing wear and approximately planar, so that the cleaning effect of the cleaning rod is impaired.
    The invention is based on the object to provide a device of the type described above, which avoids the disadvantages mentioned, which allows in particular a structurally simple manner a wear-resistant contact between the component and the counter element, thereby optimizing the effectiveness of the wearing component allows.
    The solution of this object is achieved according to the invention by a drafting system with the features of independent claim 1.
    The dependent claims have advantageous developments of the invention the subject.
    The invention will be explained in more detail with reference to exemplary embodiments shown in the drawings.

    Referring to Fig. 1, a drafting system S, e.g. Trützschler track TD 08, available. The drafting system S is designed as a 4-over-3 drafting system, that is, it consists of three lower rollers I, II, III (I output lower roller, II middle lower roller, III input lower roller) and four top rollers 1, 2, 3rd 4. In the drafting system S, the warp of the fiber structure 5 takes place from several slivers. The delay is composed of pre-delay and main delay. The pairs of rollers 4 / III and 3 / II form the Vorverzugsfeld, and the roller pairs 3 / II and 1.2 / I form the main drafting zone. The output lower roller I is driven by the main motor (not shown) and thus determines the delivery speed. The input and middle bottom rollers III and II are driven by a control motor (not shown). The top rollers 1 to 4 are pressed by pressure elements 91 to 94 (loading device) in pivotable about pivot bearing arms 11a to 11 d (see Fig. 2) against the lower rollers I, II, III and obtained via friction thus their drive. The direction of rotation of the rollers I, II, III; 1, 2, 3, 4 is indicated by curved arrows. The fiber structure 5, which consists of a plurality of slivers, runs in the direction A. The lower rollers I, II, III are mounted in punches 16a, 16b (see Fig. 2), which are arranged on the machine frame 17. The top rollers 1, 2, 3, 4 are mounted in holding elements 13a, 13b (see FIG.
    According to Fig. 2, the upper roller 4 is associated with the portal-shaped pressure arm 11a, which consists of two lateral pneumatic cylinders 9a1und 9a2 (pressure elements), a common support member 12a, two holding elements 13a and 13b and two intermediate elements 14a1und 14a2. The pressure arm 11a is pivoted together with the top roller 4 about a pivot bearing 10 which is attached to the punch 16a. The holding elements 13a and 13b are - seen in side view - angled (rectangular), wherein the one angular arm of the holding member 13a is rotatably mounted in each case in the region of its free end on the pivot bearing 10. The angle arm of the retaining element 13b has in the region of its free end a (not shown) part of a locking device, the closure latch can be brought into and out of engagement with a bolt fixedly mounted on the machine frame. The pressure arm 11a is shown in the unlocked and opened position. 21 denotes a cleaning strip.
    According to Fig. 3, the upper roller 4 is associated with the portal-shaped pressure arm 11a. (The upper rollers 1 to 3 - not shown - a corresponding pressure arm 11 assigned.) The pressure arm 11a is formed as a housing made of glass fiber reinforced plastic and produced by injection molding. The housing is an integral component that is unitarily formed and includes the support member 12, the two bodies of the pressing members 9a1 and 9a2 (impression cylinder), two intermediate members 14a and 14b, and two support members 13a and 13b. The cleaning strip 21 is in operation on the top roller 4 and acts as a scraper. The cleaning strip 21 has at its two ends in each case a fork 23a, 23b, which, e.g. are screwed to the cleaning strip 21. The forks 23a, 23b are made of vibration-damping plastic, to avoid vibration excitation of the cleaning roller 21 on the upper roller. The arrangement on the piston rods 19a, 19b, an exact position of the cleaning bar 21 is realized to the upper roller 4, since the guidance of the upper roller 4 and the position of the piston rods 19a, 19b is ensured by the pressure arm 11a.
    The forks 23a, 23b rest on two elastic elements, e.g. two O-rings 20a and 20b, respectively, which are attached to the piston rods 19a and 19b, respectively. As a result, the cleaning bar 21 against falling, e.g. from the piston rods 19a, 19b, prevented. To remove the cleaning strip 21 must be pulled only from one side with the fork on the elastic element. The insertion of the cleaning strip 21 is reversed. The forks 23a, 23b can rest on the O-rings 20a, 20b by gravity. Conveniently, there is a clearance between the forks 23a, 23b and the push rods 19a, 19b.
    The cleaning strip 21 is formed as a rod 211mit circular cross-section. At each end of the rod 211 there is a hexagonal plug 212, 213 in one piece (see Fig. 4a). In Fig. 4 213 is shown visibly, while the hex plug is installed in the fork 23 a is present. The plugs 213is associated with a fork 23a and 23b, respectively. The forks 23a and 23b each have a hexagonal socket 232bzw. 233, in which the plug 213 are inserted form-fitting. The forks 23a, 23b are attached to the cleaning strip 21 after insertion with screws 24a bzw.24b.
    If a surface portion of the cleaning bar 21 is worn by frictional engagement with the upper roller 4 during operation and thus the cleaning effect is impaired, the cleaning rod 21 is removed and the mounting screws 24a, 24b released, the forks 23a, 23b deducted from the stretchers 213 and Cleaning rod 21 is rotated axially by one pitch. Subsequently, in the reverse order, the forks 23a, 23b are placed on the plug 213, the fastening screws 24a, 24b tightened and the cleaning rod 21 re-installed. In this structurally simple manner, a predetermined untapped area of the rod 21 is set and locked.
    In Fig. 5a, a bearing element 16a (punch, drafting stone) for the end region of a lower roll, e.g. Bottom roller III, with two built-in wear pins 251, 252 shown. The Verschleissstifte 251, 252 are in vertical holes 261bzw. 262formschlüssig arranged (see bore 261in Fig. 5b) and protrude with a part of its lateral surface (cylinder portion) via an open slot in the wall portion of the bore 261, 262 outwardly out.
    Each bearing element 16a and 16b has two lugs 161bzw. 162, which are arranged parallel to one another and enclose an intermediate region, in each of which a fastening lug 18a, 18b (see Fig. 2a) is provided on the bearings 15a, 15b for the lower roller III. These attachment lugs 18a, 18b are wearingly engaged with the wear pins 251, 252. The approaches 161bzw. 162is each a fastener 271, 272 for the Verschleissstifte 251bzw. 252zugeordnet. The fasteners 271, 272werden with screws 281bzw. At the beginnings 161bzw. 162befestigt. As shown in FIG. 6a, each wear pin 251 has at its two ends in each case a plug 25, 25 which is positively engaged with a recess 27 in the fastening element 271. In the example, the plug 25 consists of two parallel cut-outs of the Verschleissstiftes 251 and the recess 27 from a mounted in the fastener 271 groove with a rectangular cross-section.
    In operation, when the cylinder jacket surface protruding from the slot of the bore 261 is worn, the wear pin 251 is withdrawn from the bore 261 after removal of the fastener 271, rotated axially 90 °, turned 180 °, and re-installed and anchored in the bore 261 in that position , In this way, an unworn portion of the wear pin 251 protrudes out of the slot.
    As shown in FIGS. 6a and 6b, the plugs 25 and 25 are arranged at the two ends of the wear pin 251 rotated 90 ° to each other and aligned.
