Definitions

  • the invention relates to a Fadenmessunter réelle according to the preamble of claim 1.
  • Fadenmessunterello be used on jet looms, especially air jet looms to deduct weft thread material from a thread storage on the storage body in adjacent or separated windings vitespeichem forward the stored turns of thread towards the front end of the storage body, for each entry process only one measured by the stop number from turns to the trigger to release, initiate the shot, and finally, for example stop the shot by means of the stopping device.
  • thread measuring devices are known WO-A-02/33157 having a storage body with an extremely small diameter and a stop device with a stop pin, which measures the respective number of thread turns to be released for withdrawal and terminates the shot, while a withdrawal direction in front of the storage body arranged, controlled thread clamp initiates each shot.
  • the turns formed by the take-up on the storage surface are successively pushed forward, while they move the stop pin to a predetermined end position. Since each shot is initiated by the controlled thread clamp, and the end of the storage body is just past the end position of the stop pin, multiple turns of thread are released across the front end in a tubular configuration until the start of the next shot, up to and during the shot inner support so to speak, remain free in the room and then pulled back to the stop pin back.
  • the storage body consists of a respect to the axis of the storage body eccentric, substantially cylindrical housing having a substantially smaller outer diameter than the outer diameter of the storage body, as well as in the cylindrical housing radially adjustable L-shaped brackets.
  • the cylindrical housing is covered at the front end of the storage body by a radially disposed wall.
  • the radial legs of the bracket are slightly set back against the wall.
  • a plurality of stop pins are peripherally driven by a gear, which are extended and retracted alternately over the outer periphery of the storage body.
  • the invention has for its object to provide a Fadenmesstrade réelle, in the operation with high firing frequency and firing speed looping is reliably avoided.
  • the extension part provides the thread turns before and during the shot only a local inner support.
  • the support and the counter surface converging to the support cause each Fadenwindung free on the front end of the storage body practically almost only selectively supported on the support, while the trigger over the rest of their 360 ° extension without any inner support and without balloon effect inside in Essentially to extend the axis of the storage body is pulled.
  • the friction on the support and caused by the support during the withdrawal movement irregularity in the yarn path lead surprisingly reliable that each foremost Fadenwindung separated and withdrawn alone. This eliminates the risk of looping.
  • the oblique mating surface further prevents turns from being tightened on the extension portion, as each contracting turn is deported by the slope of the mating surface from the extension portion.
  • the counter surface can start at the outer diameter of the storage body.
  • the extension part is a kind of right-angled triangle, eg as a two-dimensional flat surface or only of rods which define a catheter and the hypotenuse of the at least substantially right-angled triangle.
  • each thread turn riding on it is supported by the central overhead position of the support so that it can not rotatably shift about the axis of the storage body.
  • Line contact between the turns of thread and the support is sufficient to provide the required suspension support, and also results in low frictional resistance to the turns of thread. Nevertheless, it is even possible to use flat or broader conditions, such as to keep the thread turns wide open by taking advantage of the natural curvature storage capacity of the thread material.
  • the extension part could e.g. Alternatively take a 9 o'clock position on the storage body.
  • the storage surface of the storage body is defined by outer surfaces about the axis with spaces of distributed fingers.
  • the fingers end, preferably, freely at the front end of the storage body.
  • the overlay of the extension extends the outer surface of one of the fingers. It is advantageous if there is no tangible transition between the support and the outer surface of the finger.
  • the extension part, the support extends the outer surface of the finger, should be appropriate attached directly to the finger.
  • the extension part is even formed integrally with the finger.
  • the extension part could additionally be supported on the storage body, for example on a diametrically opposite other finger.
  • extension part Since different shapes of the extension part may provide optimal effect for different thread materials, it is expedient if the extension part is mounted exchangeably on the storage body against another extension part formed with a different shape.
  • the extension part is a rod, e.g. made of plastic or wire.
  • a blade could be provided, the cutting edge or back forms the support.
  • the oblique mating surface which shunts contracting turns of thread from the extension part, is expedient even incorporated into the extension part.
  • the extension part may be a slate cone or truncated cone.
  • the base diameter of the cone or truncated cone may be smaller than the diameter of the front end of the storage body. Then each thread turn reaching the overlay relaxes immediately over most of its 360 ° extension.
  • the cone or truncated cone forms both the support and the counter surface.
  • a cone or truncated cone as an extension part could have a straight, convex or concave generatrix.
  • the extension part could also be a hollow body with upper and lower narrow sides and a rectangular or oval cross-section.
  • the cross-sectional width should correspond at least to the width of the outer surface of the finger from which the extension part extends.
  • the support can be conveniently formed by a narrow side of the hollow body, this narrow side should be either slightly curved or rounded in the middle area flat and rounded at the edges.
  • the opposite narrow side of the hollow body forms in the withdrawal direction obliquely to a tip region of the hollow body rejecting counter surface.
  • the mating surface could begin within the outer diameter of the storage body, if space is needed in this area for other thread control members of the Fadenmesstrade convinceds.
  • the support may be parallel or converging to the axis. A certain convergence or falling curvature may facilitate forward feeding of the turns of thread and / or the consumption of turns of thread on withdrawal.
  • the mating surface has an end portion approximately parallel to the axis of the storage body, the tendency of the loosened turns of thread to lift off the support during withdrawal is alleviated.
  • the stop pin taken along by the thread windings it is expedient to provide the stop pin on a location of the storage body lying below in relation to the direction of gravitation.
  • the stop pin expediently cooperates with the finger, which lies diametrically opposite the finger extended by the rest.
  • the extension part should have a geometric shape, which ensures that at the end of the withdrawal process extending thread in no case gets caught on the extension part, but freed from the extension part and extends directly to the stop pin.
  • stop pin which is arranged in and against the withdrawal direction and radially movable, engages in a guide slot of the storage body, which defines the end position of the stop pin in the thread turns caused by the movement of the stop pin, in which the stop pin the entry process completed.
  • a controlled thread clamp downstream of the front end of the storage body is appropriate.
  • a lying below the storage body in the withdrawal direction behind the front end guide surface makes an additional, the withdrawal behavior favoring support the freed yarn turns, but only from the outside of the tubular configured, released filament winding.
  • the cover surface is arranged to be yielding outwards and defines a thread turn control gap with the outer surface of the finger and the support. In this gap, the turns of thread are arranged next to each other in order and guided while pushing.
  • cover surface is elastically biased from the outside against the outer surface of the finger and the support. Irregularities in the thread and / or knots can thus happen unhindered.
  • the cover surface In order to shift the yarn turns along their path from the finger to the support surface in a controlled manner, it is expedient for the cover surface to extend beyond the end of the support, starting at a distance from the take-up element along the finger and the support. In the region in which the cover surface extends beyond the end of the support, the cover surface suppresses the tendency of the released turns to ascend upon withdrawal.
  • the cover surface is formed by the underside of a spring element. This can be flat or rod-shaped or linear.
  • the spring element is a leaf spring, which is resiliently held in a stationary support.
  • the leaf spring is resiliently deflectable about a tilt axis, which extends approximately parallel to the storage body axis and laterally offset from the contact region between the leaf spring and the support is arranged.
