Definitions

  • This invention relates to the sliding guide which is provided in the revolving flat card for guiding the flat bars in their working positions.
  • each sliding guide is formed by a plastic element provided on the flexible arch.
  • the plastic element is not only provided on the flexible bend, but also partially wraps around the toothed belt wheels, which deflect the cover bars at the ends of the sliding guide.
  • the tensile forces generated by the flat bars on the plastic element therefore act as wrap pressure on the toothed belt wheels, which has caused the special solution according to DE-A-4108921.
  • the invention provides, in the aforementioned first aspect, a flat bar conveyor system for a revolving flat card, the flat bars being fastened to the traction means in such a way that the flat bars are conveyed through the traction means at all points, characterized in that at least one plastic element is fastened in this way to each guide bow of the card that the flat bars are guided in their working positions by the plastic elements, the flat bar guide being designed at the entry point where the flat bars are brought into contact with the plastic elements in such a way that no load peaks occur on the plastic elements.
  • the flat bar guide at the entry point can be designed such that the contact surfaces of the flat bars approach the guide surface of a plastic element in a direction almost tangentially to the curvature of the guide surface.
  • the attachment of the plastic element to the arch is preferably outside the area where the flat bars are guided by the plastic element, which significantly improves the accessibility of the attachment.
  • the application of the flat bars to the plastic element without load peaks is preferably achieved without special formation of the flat bars themselves. This can be done, for example, by providing an inlet element that connects to the plastic element.
  • the guiding of the flat bars through the traction means can, however, be so precise that the desired effect both without special training of the Flat bars as well as without an additional guide element is achieved.
  • the flat bars exert frictional forces on an elongated plastic element. These frictional forces act on the one hand in the wear of the plastic element, on the other hand in the tensile force in the plastic element. These statements apply both in the cases where the plastic element wraps around a deflection roller and in the cases where no wrapping is provided.
  • the invention provides a plastic element as a sliding guide for the flat bars of a revolving flat card, characterized in that means are provided to generate a signal when the wear on the plastic element exceeds a predetermined amount.
  • the invention provides a plastic element as a sliding guide for the flat bars of a revolving flat card, characterized in that the element is connected to a carrier in such a way that the tensile forces at no point in the plastic element exceed a predetermined dimension.
  • the invention provides a plastic element as a sliding guide for the flat bars of a revolving flat card, characterized in that an elongated plastic element is composed by a plurality of individually interchangeable links.
  • the invention provides a revolving flat card, which has a flexible arch for guiding the flat rods during their run through the work area, characterized in that the sliding surface is on the flexible arch is formed by a plurality of individual elements which are distributed over the arch.
  • the arrangement can be made such that a flat rod simultaneously touches several of these elements when sliding over the arch.
  • the individual elements are preferably attached individually to the arch.
  • the flat bars must be placed on the arch without destroying the individual elements in the entry area. This can be done, for example, by providing an inlet element which adjoins the bend. However, the guiding of the flat bars can be so precise that the desired effect is achieved both without special design of the flat bars and without an additional guide element.
  • the individual elements in the infeed area can, however, be specially selected in order to withstand the forces generated during application.
  • Figure 1 shows a revolving flat card according to DE-A-3835776 with a frame 10, Briseur 16, reel 17, customer 21 and Traveling cover set 19.
  • the traveling cover set 19 comprises a hundred and six flat bars 29, of which forty-one are in the working position, two endless traction means 28 (for example chains or toothed belts), of which only one such means is visible in FIG. 1, and four pairs of deflection wheels 22, 23, 24.25, of which only one wheel of each pair is visible in FIG. 1.
  • the wheels of the pair 25 are driven to move the traction means in the direction of the arrow 30.
  • the traction means or their respective wheels form two movement paths in a vertical plane.
  • the reference numerals 41 to 49 indicate a modular division of the outer surface of the drum according to DE-A-3835776. This division is of no importance for the present invention and is not explained in more detail.
  • Each flat bar 29 is fastened at one end to one and at the other end to the other traction means 28 and is at right angles to both.
  • the rods 29 are therefore moved along the paths during operation when the traction means 28 are moved along their own lengths by rotating the deflection wheels 25.
  • the rods 29 are fastened to the traction means 28 in such a way that the fastening means (not shown) must be loosened in order to remove the rod from the traction means.
  • fastening means not shown
  • the machine frame 10 comprises two side plates 32 (FIG. 2) (side walls), which receive the bearing axis 31 for the rotatable drum 17 and carry support parts 27 (FIG. 1) for the cover set 19.
  • the side shields are shown in FIG. 2 without details, but are explained in more detail below with reference to FIG. 4.
  • the preferred flat bar conveyor system generally corresponds to the arrangement according to FIG. 1 of DE-C-1115621, which is shown in FIG. 3 of this application.
  • the Deflection rollers 22, 23 (only roller 23 shown in Fig. 3) is formed with teeth 20.
  • the flat bars 29 are fastened at their two ends to a flexible band 28A (for example a toothed belt) by means of clamping devices 29A.
  • the clamping devices 29A are formed as teeth that match the gear wheels 22, 23.
  • a flat rod is placed against a sliding guide surface 52 (FIG. 3), the belt path being tensioned between the wheels 22, 23 in order to press the flat rods against the sliding guide surface 52 .
  • This flat bar conveyor system is not absolutely necessary, but is taken as an example in the explanations below. Smaller changes in the clamping devices are explained below with reference to FIG. 4.
  • the outer surface of the drum 17 is provided with a set, the surfaces of the flat bars 29, which are directed outwards from the cover set 19, likewise.
  • Much of the carding work is done between a cover bar and the reel as the bar moves from the entry point E (Fig. 1) to an exit point A, this movement in the same direction as the rotation of the reel (in unison) or (as shown in Fig. 1) opposite to the reel movement can take place.
  • the flat rod (or its clothing) must maintain a precise distance from the drum. This distance is not determined by the cover set 19 itself, but by the aforementioned slide guides 52, which are provided on the upwardly facing surfaces of the side walls 32. Each slide guide can be formed (and even adjusted) exactly in relation to the axis of rotation of the drum, as will now be explained with reference to FIG. 4.
  • each sliding guide is formed on a respective flexible arch 34.
  • the bow 34 has lugs 35 which are mounted on the respective side plate 32 by means of adjustable fastenings (not shown).
  • the flexible sheet 34 can be curved more or less with respect to the axis of rotation of the drum 17 in order to influence the design of the sliding guide with respect to the drum.
  • each flexible sheet is provided with a plastic element which forms the actual sliding guide, this element being guided around the deflection wheels 22, 23.
  • a plastic element 50 (e.g. a plastic strip) is attached to the flexible sheet 34 in such a way that it forms the sliding surface 52 for the flat bars 29.
  • the plastic element is in the form of a plastic strip, which is inserted in a groove 51 in the upward surface of the sheet 34.
  • the thickness of the strip is greater than the depth of the groove, so that the strip protrudes from the groove.
  • the protruding part of the strip (or the surface facing upwards thereof) forms the aforementioned sliding surface for the flat bars.
  • the element 50 extends along the arc 34 away from a fastening 54 which lies outside the region G (FIG. 1) which is covered by the flat bars 29.
  • This attachment 54 is located in front of the entry point E (viewed in the direction of movement of the flat bars).
  • Each flat bar 29 is provided at each end with a "flat head" which includes both a slider 29B and the aforementioned clamping device 29A.
  • the slider 29B is integrally formed with the working body of the rod 29, while the clamping device 29A is a first one, with the slider formed from one piece, part and a second removable clamping part.
  • the clamping part is fastened to the first part by a screw 27 (FIG. 4), the belt 28A being clamped between the first and the second part.
  • the sliders 29B of the flat bars 29 in their working positions sit snugly on the plastic element 50, so that the distance between the lid set and the drum set is determined by the position of the plastic element 50 relative to the flexible sheet 34.
  • the flat bars 29 therefore exert tensile forces on the plastic element 50 in the direction of the flat bar movement 30. It is therefore only necessary to also fasten the plastic element 50 at its end remote from the fastening 54 if the direction of movement of the flat bars 29 must be expected to be reversed.
  • no second fastening is provided outside the working area G of the flat bars 29, because such additional fastening could possibly lead to malfunctions if the element 50 is elongated during operation.
  • the sliders 29B are normally provided with two sliding surfaces 56, 58 (FIG. 5), each of which is approximately 1/3 the width of the cover rod and therefore sit snugly on the curved sliding surface 52 of the plastic element 50 when the flat rod 29 is opposite the Flexible arch 34 has taken up its working position.
  • the flat rod sliding surfaces 56, 58 are normally ground at right angles to the two side surfaces 60 of the slider, which leaves an edge K at the transition between these surfaces. This edge K can lead to problems at the entry point E, as will now be explained with reference to FIG.
  • the sliding surfaces 56, 58 of the flat bars 29 should move approximately in a tangential direction with respect to the curved element 50 during the entry. If this is not the case, either the front or the rear edge K of the flat rod sliding surfaces as the first part of the rod 29 will touch the plastic element 50 and result in a strong scraping effect (if not a "peeling").
  • edges K of the flat bars 29 are not damaging Trigger effects, even if the sliding surfaces 56, 58 of the flat bars do not move exactly tangentially with respect to the plastic element 50 when they run in.
  • this makes the production of the flat bars 29 more expensive, in particular because this measure is not necessary for flexible sheets 34 without plastic sliding surfaces.
  • FIG. 7 A suitable practical solution is shown in FIG. 7 and consists in providing an inlet element 62 which is located in the “wedge gap” between the inlet slider of the flat bars 29 and the plastic element 50.
  • the inlet element 62 has an inlet surface 63 which adjoins the sliding surface 52 of the plastic element 50 approximately tangentially. Any unsuitable angular positions of the flat bars 29 can therefore be corrected by contact with the inlet element 62 before the first contact with the plastic element 50. Since the inlet element 62 is located in front of the actual inlet point E, it does not matter that the position of the cover rod on the inlet element 62 relative to the drum 17 is not ideal. For the same reason, wear marks on element 62 are of secondary importance.
  • the measures already described can avoid peak loads in the plastic element 50. A gradual wear of the plastic element 50 can not be avoided and should not. It is an advantage of using such a plastic element 50 that it is particularly subject to wear, while both the flat bars 29 and the flexible sheet 34 are spared.
  • the flexible arch can be manufactured precisely.
  • the plastic element 50 according to this invention is inexpensive to manufacture, yet is dimensioned precisely, so that the necessary precision is ensured after installation. Element 50 is easy to replace.
  • Such an exchange could e.g. with periodic maintenance work.
  • the variant now addressed has two current conductors 72 (metal wires) embedded in the cross section of the element 70, the current conductors 72 extending over the entire length of the element 70 and normally being insulated from one another by the plastic. With a predetermined degree of wear of the plastic element 70, a flat rod 29 touches the current conductor 72 and forms a current-conducting bridge between them.
  • the current conductors 72 of the plastic element 70 are connected to a voltage source 74, so that a current flows into the current conductor 72 during the aforementioned bridging (FIG. 9).
  • a sensor S in an evaluation unit 76 reacts to this current and generates a display, on a card of the card with the indication that the flat bars 29 are now in contact with the current conductors 72.
  • a plastic element according to this invention is in any case exposed to considerable tensile forces during operation.
  • the height these tensile forces depend on the frictional forces between the sliders of the flat bars and the plastic element. These frictional forces in turn depend on the total number of flat bars in the working position, the curvature of the flexible sheet and the sliding properties of the surfaces in contact.
  • the design of the card and its function set limits for the designer to influence the parameters mentioned. The machine designer must therefore expect the high tensile forces mentioned in the plastic element and take them into account accordingly. If no countermeasures are taken, these tensile forces add up in the longitudinal direction away from the fastening, which can lead to particularly serious effects at the end of the plastic element remote from the fastening.
  • relief means are provided in the variants according to FIG. 10, which transfer the tensile forces prevailing therein to the flexible bend at least at one point between the ends of the plastic element.
  • the plastic element is thereby divided into at least two longitudinal parts, so that the summation of the tensile forces over the entire length of the plastic element is prevented.
  • FIG. 10 there is only one such relief means 82 for the element 80.
  • This arrangement generally corresponds to the variant according to FIG. 5, namely in that the plastic element 80 is inserted in a groove 81 in the flexible bend 79.
  • the relief means 82 consists of a pin 82 which is pressed into corresponding holes in the side walls of the arc 79 forming the grooves 81 after a suitable bore has been formed in the plastic strip 80.
  • FIG. 11 shows a further variant with many such places, at which the tensile forces are transmitted to the flexible sheet. This is done by means of "teeth" 84 on the edges of the element 86, which fit together with corresponding teeth 88 in the flexible sheet.
  • teeth 88 on the flexible arch can be formed on clamping elements 92 which connect the plastic element 86 to the flexible arch 90.
  • the plastic element 86 is embedded between the clamping elements 92, which requires a corresponding design of the flat rod head (not shown) in order to avoid contact of the slider 93 or the clamping device 95 with the clamping elements 92.
  • the aforementioned clamping elements 92 can extend over the entire length of the plastic element 86, or they can be distributed along the plastic element 86 as individual elements.
  • Figures 13 and 14 show a variant of the plastic element, according to which this element is composed of a plurality of individual pieces.
  • the figures show only one example of this configuration of the plastic element 100, according to which each section 102 covers the flexible arch 104, angled side parts 106 engaging in grooves 108 in the side surfaces of the flexible arch 104 in order to hold the plastic element on the arch.
  • the individual pieces 102 can be pushed together and held by end stops (not shown). However, each piece 102 (e.g. by pins 105, Fig. 14) can be fixed to the bow 104.
  • each piece is preferably cut obliquely at its ends, namely obliquely, both in relation to the longitudinal direction of the assembled element and in relation to the transverse direction (perpendicular to the length of the plastic element).
  • the plastic element can not only be divided into sections in the longitudinal direction. For example, several relatively thin strips are placed side by side to form a sliding surface for the flat bars.
  • a possible embodiment is shown in FIG. 15, and this last-mentioned figure also shows that such a relatively thin element 110 is not necessarily straight, but can have a serpentine configuration.
  • each element 110 can be pressed into a groove formed for this purpose in the flexible bend 112.
  • 16 also shows that this serpentine design of the plastic element is also possible when using a single plastic element 114 per flexible sheet 116.
  • This variant has the advantage of a certain self-cleaning effect, since when the surface is scraped through the flat bars, the dirt and other particles are pushed from the plastic strip 114 onto the supporting flexible sheet 116.
  • the snake-like variants have the advantage that the frictional forces no longer act as tensile forces in the elongated plastic elements.
  • the deformation forces generated in the plastic are released directly to the side surfaces of the grooves receiving the plastic elements. In this case, additional fastening is unnecessary if the curvature of the element is sufficiently pronounced.
