Definitions

  • the invention relates to a measuring delivery device according to the preamble of patent claim 1.
  • a known measuring delivery device (WO 98/37265) the storage body in the winding direction in front of the stop element is assigned an adjustable between a braking position and a passive position brake shoe, the task is to temporarily the thread section between the last last turn and the stopper moved to the stop position stabilize. The brake shoe is moved in response to the adjustment of the stop element in the braking position and back again.
  • the invention has for its object to provide a measuring delivery device of the type mentioned, which is characterized during and after the thread withdrawal by an improved thread control. Part of the task is to improve the thread control in a measuring delivery device that completely releases several turns for withdrawal from the rod cage with a very small-diameter rod cage from the winding action by windings are pushed off substantially axially from the rod cage, then without internal mechanical support freely in space remain, and be consumed before collapsing by the entry process.
  • the brake element located in a permanent braking position with respect to the rod takes surprisingly when pushing forward the turns on the rods and / or during the deduction no negative impact on the thread geometry or the insertion speed, although each thread winding or more simultaneously temporarily the braking resistance between the thread support surface and the braking surface is exposed. If necessary, the thread windings are placed close to each other when passing through the braking zone, possibly even brought into intimate contact, without losing the well-ordered configuration on the rod cage. This is probably due to uniform permanent action.
  • the brake element at least a large part of the thread on the bars controlled so that the windings maintain their proper configuration and the voltage increase over frictional forces is largely consumed.
  • the braking member may contact or even be resiliently pressed against the thread support surface, or may be positioned a predetermined distance from the thread support surface which is less than the amount of turn of the thread. As a result, each turn experiences a predetermined braking effect.
  • At least two brake elements are arranged symmetrically.
  • the turns can not be oriented obliquely.
  • the brake element is designed or arranged resiliently substantially radially to the rod cage axis. This creates a well-measured braking effect, in which the brake element can yield. This is also important if, for example, a thickening of the thread must happen.
  • the resilient compliance of the brake element also ensures an immediate return the braking element in the predetermined permanent braking position, so that all continuous windings are exposed to substantially the same braking effect.
  • the braking element with the thread-carrying surface forms a tapering inlet gap and an expanding outlet gap, between which there is a braking zone along which the thread-carrying surface and the braking surface are at least substantially parallel to one another in the drawing-off direction. Due to this design, the braking effect gradually increases to a maximum, then remains z-B. temporarily at the maximum, and then gradually decreases again. This kinematics is important for a clean thread control. Occurs during the braking phase with the maximum braking force from the trigger side forth a voltage increase, then this is at least largely consumed by the braking effect, without bringing the forwards in the withdrawal direction turns disorder or cause a yarn breakage.
  • the braking element is arranged at an end portion of the thread support surface lying at the withdrawal end, so that the turns are only brought into contact with each other immediately before the withdrawal end of the rod cage and thereby braked in a controlled manner.
  • the circumferentially seen width of the thread support surface or the braking zone decreases in the withdrawal direction, whereby the braking effect decreases, although the specific surface pressure increases.
  • the braking zone can theoretically be linear. In order to treat the thread as gently as possible, it is expedient, however, to form it in the circumferential direction with a finite width.
  • the braking element is a runner, which is guided in an external stationary guide substantially radially to the rod cage axis movable and acted upon by a spring in the direction of the rod.
  • the friction properties of the braking surface and the spring force lead to a predetermined, well-metered braking effect.
  • the extension stroke of the runner from the guide is limited by a stop, so that the permanent braking position is a braking position, in which the braking surface is applied either with a predetermined contact pressure on the thread support surface or maintains a predetermined distance.
  • the spring force with which the braking surface acts is expediently adjustable in order to be able to adapt to different thread qualities.
  • braking elements are provided in a permanent braking position at more than two to a maximum of all bars.
  • a particularly symmetrical distribution of the braking effects results with four braking elements offset by approximately 90 ° from each other.
  • an engagement opening for the stop element is provided in a selected rod, and is in the winding direction before the engagement opening for the same rod or for a provided in the winding direction preceding a brake rod in the permanent braking position.
  • the first braking effect occurs at an optimally short distance from the stop element on the thread when the stop element ends the thread withdrawal.
  • each brake element is a spring tongue, which is held stationary in the withdrawal direction before and / or behind the braking zone.
  • a spring tongue requires little installation space and is able to produce a very precisely predictable braking effect.
  • the brake elements are arranged in a ring body comprising the rod cage, which defines, so to speak, a common guide and support for all brake elements.
  • each rod is associated with a brake element, and are provided at least for some brake elements Passiviervorraumen.
  • the number of actually active and permanently braking brake elements can be selected as needed.
  • the brake elements held in the passive position exert no braking effect.
  • the effective diameter of the rod cage is variable to make an adjustment to the respective weaving width, and the brake elements or their guides should be arranged radially adjustable to a diameter change of the Rod cage again to be able to set the desired braking effects.
  • a particularly expedient embodiment is characterized in that the rod cage has an outer diameter between about 20 to 60 mm, that along a selected rod is provided in the withdrawal direction exclusively by the thread windings into a defined stop position transportable stop element, and that at least at two order each in about 90 ° relative to the selected rod in the circumferential direction staggered rods per a brake element is provided in a permanent braking position. So that at least the last arranged in the winding direction before the stop element braking element at the voltage increase after completion of the entry process, the energy consumes as desired and holds the thread turns controlled, the yarn braking zone should be aligned at this braking element in the circumferential direction at least approximately to the defined stop position.
  • the selected rod is one of the lowermost rods of the rod cage positioned with a substantially horizontal rod cage axis, and the at least two diametrically opposed brake members lie approximately in the same horizontal plane.
