Definitions

  • the invention relates to a weft measuring feeder according to the preamble of claim 1 or according to the preamble of the independent claim 2.
  • a measuring feeder is known from EP-A-0 060 234 and EP-A-0 253 359, the storage drum of which consists of several segments separated in the circumferential direction. Some of the segments can be adjusted radially asymmetrically to the storage drum axis in order to change the circumferential length of the storage drum.
  • the stop device contains only a single stop element, which is retractable in order to release the thread for withdrawal, and is engaged again shortly before reaching the predetermined thread length in order to measure the thread length.
  • an actuator for adjusting the segments is also provided during operation in order to set or readjust the correct thread length.
  • EP-A-0 253 359 also describes a measuring feeder whose storage drum has an unchangeable diameter and a fixed circumferential length.
  • the stop device contains a plurality of stop elements distributed in the circumferential direction around the storage drum, which can be individually controlled via a control device in order to assemble the predetermined thread length from entire turns and from fractional turns, which can be adjusted by the circumferential spacings of the stop elements.
  • the thread length is set such that the shortening occurring due to the thread tension stored in the elastic windings is taken into account when the pulled-off thread section is relaxed is.
  • a high speed level and / or a high thread tension occurs during mixed change weaving if, in the event of a feeder malfunction (yarn break), another feeder takes over the function of the disturbed feeder.
  • a high level of speed can also occur briefly when weaving patterns with blatant pattern variations.
  • the thread length can only be set in steps which depend on the pitch of the stop elements.
  • the spacing between the divisions cannot be very small for constructional reasons and for reasons of cost. In some cases, the set thread length is therefore longer than actually required, which also means expensive waste of thread material.
  • the invention has for its object to provide a weft measuring feeder either of the type specified in the preamble of claim 1 or in the preamble of the independent claim 2, which is structurally simple and reliable, and in which the thread length is independent of the storage drum type as low as possible Loss of thread material and without risk of short weft threads can be adjusted optimally short and precisely.
  • the thread length can be adjusted optimally short and precisely by means of the radially adjustable segments, because in the case of a high thread speed level and / or a high thread pull-off tension the spreading body is temporarily and quickly extended in order to wind the threads on the storage drum for this operating condition to enlarge and thus largely compensate for the greater shortening of the thread section that is drawn off when the thread is relaxed.
  • the design and control engineering concept of the measurement feeder remains essentially unchanged. The expansion body is extended so quickly by the energy accumulator that an immediate adaptation to the changing situation takes place.
  • the expansion body works with its energy accumulator in addition to the diameter adjustability given per se and allows an additional, rapid increase in the thread length during operation if the danger of too short weft threads occurs with the thread length set short with regard to low rejects.
  • the normal diameter adjustability using the radially adjustable segments would be too sluggish for such a quick adjustment.
  • the thread length can be finer graded with the spreading body even with large spacing distances between the stop elements with the aid of the spreading body, because with the spreading body the spacing distances between at least some stop elements are increased becomes.
  • the construction effort for modifying the storage drum is low.
  • the expanding body is also rapidly extended at a momentary high speed level and / or with increasing thread take-off tension from the supply spool in order to enlarge the windings on the storage drum to compensate for the greater shortening to be expected when the drawn-off thread section is relaxed.
  • the winding length is expediently increased in at least one step, specifically temporarily, ie only for the operating condition which is critical with regard to compliance with the set thread length.
  • the movement variants according to claim 4 lead to the same result in different ways, namely an adjustment of the winding length in the supply.
  • the feed element which is wobbled relative to the storage drum, assumes a double function according to claim 6 because it uses its kinetic energy to extend and possibly reset the expansion body.
  • permanent or switching magnets or at least one permanent magnet is used as an energy store.
  • the expansion body is a flap which is pivoted outward about an axis approximately parallel to the drum axis.
  • the trigger is actuated and actuated from the outside, and is brought into effect either between the windings or in an area outside the supply. This also takes into account the fact that because of the winding movement of the thread, the advancing thread supply and the revolving thread drawn from the outside, no direct physical access to the storage drum is possible, except for the access between two thread passages or between the relatively slowly advancing thread windings.
  • the reset device according to claim 10 has enough time to move the expansion body into the passive position when the critical operating situation is over.
  • the specified drives can be precisely controlled and enable rapid and precise movements.
  • the trigger has a double function, since it triggers and resets the expansion body.
  • a weft measuring feeder F according to FIG. 1 has a housing 1 in which a drive motor 2 for a winding member 3 which can be driven to rotate and a stationary storage drum D are mounted.
  • the storage drum D which is designed, for example, in the manner of a rod cage, defines a peripheral surface 4, to which a stop device 5 with a stop element 6 is assigned.
  • the stop element 6 can be adjusted between the stop position shown, in which the thread Y is prevented from being taken off and held in place, and a release position in which a portion of the thread Y can be removed in the direction of the arrow from a supply 7 consisting of windings overhead of the storage drum D.
  • an elongated expansion body 9 is arranged which, by means of an energy accumulator S arranged in the storage drum D, moves from the passive position 9II shown in solid lines into an over the adjacent peripheral surface 4 protruding spreading position 9I is extendable to increase the length of the winding.
  • a trigger 10 for triggering the energy store S or a lock 18 holding the expansion body 9 (FIG. 3) is provided outside the storage drum D.
  • a reset device 11 is also provided for returning the expansion body 9 to the passive position 9II.
  • the diameter of the storage drum D is adjustable (double arrow 12).
  • the motor 2 for the winding member 3 is accommodated in the housing 1.
  • the storage drum D defines with its circumferential surface 4 a support for the turns in the supply 7, from which the thread Y can be pulled off overhead and under the stop device 5.
  • the diameter of the storage drum D cannot be changed.
  • the expansion body 9 can be extended by means of the energy store S in the storage drum D into the expansion position 91, in which it protrudes over the peripheral surface 4.
  • the expansion body 9 can be returned to the passive position 9II (shown in solid lines), in which it is flush with the peripheral surface 4 or even withdraws behind it.
  • the trigger 10 and the reset 11 are arranged on the stop device 5.
  • the expansion body 9 expediently extends beyond the supply 7 on both sides in the direction of the drum axis.
  • the trigger 10 or the reset 11 engages in the area of the supply 7, or where there is an engaged Stop element 6 of thread Y does not move, ie in FIGS. 1 and 2 near the right end of storage drum D.
  • the spreading body 9 drawn in solid lines 9II in solid lines is a finger 13 of the storage drum D designed as a rod cage and is pivotably mounted on an arm 15 about a pivot axis 14 lying approximately parallel to the circumference of the storage drum D.
