Definitions

  • the invention relates to a needle roller for textile machines, in particular an opening roller for open-end spinning machines, in the roller body of which numerous needles arranged in several rows are arranged and fastened with the blunt needle end in openings in the roller body in such a way that the longitudinal axes of the needles are each connected to the one by the associated one Radius guided opening form an angle of 0 to 40 °, preferably 0 to 30 °.
  • Such needle rollers are described, for example, in Swiss patent specification 630 121. With these rollers, the needles are individually fastened in corresponding bores in the roller body, usually soldered.
  • the invention has for its object to further develop the known needle rollers for textile machines in such a way that both the manufacture and the repair of these needle rollers is technically simpler and consequently also cheaper and can also be carried out by the textile companies themselves.
  • the pinstripe advantageously consists of a plastic, as is known per se for such pinstripes.
  • the pinstrip can also consist of a suitable metal alloy, into which the needles are incorporated when the strip is cast.
  • the grooves of the roller body are machined into the roller body near the lateral surface, in such a way that the longitudinal axis of the groove runs parallel to the longitudinal axis of the roller.
  • the roller body can be designed as a separate rotationally symmetrical component and can be arranged on a corresponding bearing. But it is also possible to manufacture roller bodies and bearings from a single piece.
  • the grooves can have any cross-sectional shape. Round cross-sectional shapes are particularly simple and also advantageous in some respects (see below).
  • the pinstripes must also have correspondingly round cross-sections so that they fit tightly against the inner surface Surfaces of the grooves can be inserted into them.
  • the grooves each end in open gaps of the roll surface, so that the needles protrude through these gaps and can run in a known manner perpendicular to the roll surface or at a more or less inclined angle thereto.
  • the cross-sectional shape of the pinstripes can also deviate from the round cross-sectional shape, for example square, rectangular, hexagonal, octagonal, dovetail-shaped, teardrop-shaped or similar.
  • the cross-sectional shape of the grooves will also have to be appropriate so that the pinstripes can be picked up and stored firmly in the grooves.
  • the needles do not emerge vertically from the outer surface of the roller body, but - as is known per se - form an angle of, for example, 30 ° with the outer surface (more precisely: with the tangent to the outer surface). If this angle is to be kept unchanged after a single adjustment, it is possible to take it into account in the manufacture of the pinstrip and the roller grooves, the desired needle angles then inevitably resulting after fitting the pinstrip in these grooves.
  • the edges of the opening gaps define an angle of at least 40 ° around the longitudinal axis of the groove. This measure should be used if the needles are to form an angle deviating from 90 ° with the tangent to the lateral surface.
  • the needles In conventional needle rollers, it is known that the needles form more or less straight rows in the direction of the roller longitudinal axis. The needles of one row should preferably be slightly offset with respect to the needles of the next row, so that the needles are in a gap and no straight lines can form between the needles.
  • the roller body be arranged between two flange-like end disks, or the like in the area of the pin strip end faces against these cams. have different heights.
  • the cams of the two end disks are therefore arranged with respect to one another such that a higher cam of one disk is opposed to a lower cam of the other disk and vice versa and that the height difference of the cams corresponds to the desired distance between the longitudinal axes of the needles.
  • the arrangement can be created in such a way that the needles which follow one another in the circumferential direction are each offset by 1/10 of the needle spacing within a row. It then emerges that such a "rotation cycle" occurs three times in succession in the circumferential direction.
  • the pinstripe by means of cams or the like. to move and set, it is important that the end plates that wear the cams, be mounted in the correct position.
  • the end disks and the end faces of the roller body have interlocking registration marks. These registration marks can be pins and holes. They must be arranged and dimensioned so that they do not interfere with the smooth running when the needle rollers rotate. It must either be balanced the roller or the arrangement and dimensioning must be such that the centrifugal moments of the registration marks are the same.
  • the pin strips each have an eccentric pin on their end faces, which engages in a corresponding recess in the one end plate and that this end plate is adjustable by an angular amount that is sufficient to fit the pin strips in their grooves to adjust the positive or negative needle inclination angle.
  • the end plate must of course be lockable after the adjustment, which can be accomplished in a very simple manner by equipping the end plate with corresponding arc-shaped elongated holes instead of with holes for the locking screws.
  • the invention further relates to a method for producing a needle roller for textile machines.
  • This method is characterized in that the roller body, the bearing parts and the end disks are produced by shaping or injection molding. These manufacturing methods ensure that the highest level of economy is achieved in the manufacture. The methods cannot be used with the previously known needle rollers because of the numerous bores for the individual anchoring of the needles.
  • the needle roller shown in the drawing consists of a cylindrical roller body 1, in which numerous needles 5, arranged in several rows 2; 3; 4, are arranged. These needles 5 are each anchored with their blunt end in a pinstrip 6, which is made, for example, of plastic or metal, and fastened with this in a groove 7 of the roller body.
  • the grooves can have any cross-section; however, they should match the cross-sectional shape of the pinstripes.
  • the roller body 1 is equipped with pin strips 6 in the desired manner. Then the roller body thus prepared 1 pushed onto the bearing 9 and attached to the bearing by attaching the end plate 10.
  • the bearing 9 is equipped with a drive shaft 11, which in turn is rotatably arranged in a fixed bearing 12.
  • the front disk 13 of the bearing 9 and also the end disk 10 are each equipped with cams 14 and 15.
  • the height of these cams is different and is set up so that a higher cam follows in the circumferential direction after a lower cam.
  • the end plate 10 can be fastened with screws which extend through the screw holes 16 of the end plate 10 and engage in screw threads 17 of the bearing 9.
  • the assembled parts are shown again in FIG. 5. The same parts are labeled with the same reference numerals.
  • FIG. 6-14 different cross-sectional shapes of both the pinstrip 6 and the grooves 7 are shown. From Fig. 6 it can be seen that the cross-sectional shapes can be rectangular. In Fig. 7 they are dovetail-shaped, in Fig. 8 flattened round; 9 circular; 10 drop-shaped;
  • the pinstrip 6 is equipped on one end face 18 with eccentrically arranged pins 19. In the case of assembled parts, this pin 19 engages in a recess 20 which is located on the inner surface of the end plate 10.
  • the arrangement has the effect that, by turning the end plate 10, the pinstrip 6 is carried along via the pin 19 and the needles are consequently inclined according to the degree of rotation.
  • positive or negative inclination angles of the needles 9 can be set. After the desired inclination has been reached, the needles are locked by fixing the end plate 10.
  • the gap 8 through which the needles 5 protrude outwards is somewhat larger than the diameter of the needle at this point. It is proposed to make the gap so large that its edges define an angle of at least 40 ° around the longitudinal axis.
