Definitions

  • the invention relates to a device for storing thread-like material for weft insertion in looms, with a rotating disk carrying the material and a nozzle directed thereon for supplying air and material, furthermore with an eyelet arranged on the weft side of the loom for supplying the the disc pulled material into the weft insertion device.
  • the invention further relates to a method for operating the device.
  • the yarn to be stored is placed in a loop shape on the disk by a feed nozzle which is moved back and forth transversely to the direction of rotation of the disk.
  • the yarn is drawn off the carrier disk essentially perpendicular to the surface thereof.
  • the loop-shaped yarn deposit can easily get messy, so that individual loops can lie on top of each other.
  • the withdrawal of the stored yarn can be disturbed because often multiple loops lying one above the other can be removed at the same time instead of one after the other.
  • a vertical take-off from the carrier disk is required, because with the take-off running in the disk plane, twine loops lying one above the other would be taken off at the same time.
  • the object of the invention is to create a storage device which is particularly improved in this regard.
  • the device according to the invention consists in that a cover element, which is pressed against it under low pressure, preferably under its own weight, is arranged on the disc, under which the material on the disc can be stored in the form of a loop-shaped deposit.
  • the associated operating method consists in that the rotational speed of the disk and the feed speed of the material to be stored on it are adjusted to one another in such a way that the end of the loop-shaped material deposit stored on an annular support resting on the disk is at most up to the area of the intersection of the the feed eye lies on the center line of the support tangent.
  • the cover element can be used to deposit the loops in a particularly uniform manner without tangling the thread, e.g. B. Throwing single loops.
  • a clean, orderly intake of the material to be placed on the disk, for example thread, coming from the feed nozzle can be achieved.
  • the feed nozzle and thus the inlet section of the thread lie in an appropriate sector facing the feed eyelet, which means that when the thread is drawn off during the weft insertion, the stored deposit can be completely used up and a small piece of thread can be drawn directly from the feed nozzle.
  • a withdrawal direction lying in the plane of the storage disk is advantageous, as a result of which a particularly safe operation is achieved.
  • the cover can advantageously extend over a sector facing the feed eyelet, for example 120 ° above the disk, the thread deposit extending over approximately 90 °.
  • the thread is advantageously drawn from a section of the carrier disk which lies in the region of the intersection of the tangent placed by the feed eyelet on the center line of an annular support placed on the disk.
  • the pull-off resistance then becomes relatively low because the thread to be pulled rests only on a relatively short piece of the carrier disk.
  • a plate-shaped carrier disk 2 (diameter, for example, 140 mm) is rotatably mounted on a frame 1 attached to the loom 46 shown only on the weft side, which is set in continuous rotation by means of an endless belt drive 3 and a roller 4 from the loom drive.
  • the disc 2 carries z. B. in the outer part of a bristle 20 rest 5 z. B. from velor, needle felt or the like., On which a coming from a feed nozzle 6 thread 7 can be placed during the rotation (arrow 22) in a loop-shaped thread tray 8.
  • the thread 7 is fed to the nozzle 6 via a continuously rotating metering drum 11, which is driven synchronously by the weaving machine drive, a feed nozzle 30 and a feed tube 12.
  • the thread is drawn off a spool of the weaving machine, not shown.
  • a cover element 13 which extends over a sector B facing the feed eyelet 26 and extends approximately 120 °.
  • the lid is held in a bearing 14 which is rotatably arranged on a rod 15. This is fastened in a support 16 arranged on the frame 1.
  • the lid 13 is thus pivotable by 15 according to arrow 17. It is advantageously transparent and consists, for. B. made of plexiglass.
  • the edge 21 of the cover 13 facing the feed nozzle 6 is arranged in the direction of the circulation of the disc 2 (arrow 22) immediately after the nozzle 6.
  • a metallic part 48 adjoins the edge 21.
  • the end edge of the cover 13 is designated 10.
  • the maximum usable arc length C of the tray 8 is determined by them or the bearing 14.
  • the nozzle 6 is arranged on one leg 24 of an angle A between the connecting line 25 of the feed eyelet 26 of the weaving machine 46 and the axis 23 of the disk 2. It lies within a sector of approximately 30 °, measured from the connecting line 25 in the direction opposite to arrow 22.
  • the feed eyelet 26 of the weaving machine 46 contains a thread brake 27 which can be actuated via a linkage 28 according to arrow 29.
  • the main nozzle 31 for the weft insertion sits on the drawer 32 of the weaving machine, which is moved back and forth according to arrow 34 via a hollow shaft 33.
  • the reed is labeled 35, the weft line 36 and the thread guide channel 37.
  • the speed (e.g. 200 min- 1 ) of the disk 2 achieved by the drive at 3.4 and the feed speed (e.g. 18m / sec) of the thread 7 caused by the metering drum 11 are adjusted to one another such that the End 41 of the loop holder 8 lies in the area of the intersection 42 of the tangent 43 placed by the feed eyelet 26 on the center line 40 of the holder 5.
  • the weft thread 7 lies in the tangent 43.
  • the main nozzle 31 now receives air, so that the weft thread 7 is first drawn off at the end 41 of the support 8.
  • thread is continuously deposited on the disc 2 and this is rotated further.
  • the weft insertion is so rapid that during the movement of the eyelet 26 from the rear position, which is the most distant from the tissue stop, in FIG. 2, the upper position in the direction of the front reversing position 26a, the entire thread from the thread rest 8 is used up and still in during the stop Pieces from the tube 12 is drawn.
  • the thread 7 is braked by the thread brake 27. Now a new thread tray 8 is placed on the disc 2.
  • the cover member 13 is floating, i.e. it is only prevented by the shaft 15 from following the rotation of the disc 2.
  • the bearing 14a is open at the top.
  • the thread 7 withdrawn from the thread support 8 is pulled off the disc 2 in the plane of the disc 2, not approximately perpendicular to the disc 2.
  • the speed of the disk 2 and the feed speed of the thread 7 through the nozzle 6 are adjusted to one another in such a way that the thread support 8 is less than the arc C shown in FIG. B. only about 60 °.
  • the rest 8 should not extend far beyond the intersection 42, because otherwise the thread 7 would have to be pulled over a larger piece of the rest 5 with increased friction at the beginning of the weft insertion. There would also be an increased risk of thread confusion.
  • another design can also an air permeable, e.g. B. sieve-like pad 5 can be used through which the outflowing air can pass.
  • Di arc length C of the thread tray 8 can, for. B. at the same speed of the disc 2 and the same feed speed of the thread 7 through the nozzle 6 may also be shorter if, for example, a smaller entry length (weaving width) is present on the weaving machine. In contrast, to achieve this shorter entry length, the arc length of the thread deposit 8 can be equal to the amount C if the speed of the disk 2 is increased accordingly. In this case, the individual loops of the shelf 8 are pulled further apart, so that they lie less close together.
  • the axis 23 is in a horizontal position instead of in the vertical position provided in FIG. 1, so that the plane of the disk 2 is vertical; the lid 13 is then under low force, for. B. of one or more springs, pressed against the pad 5.
  • the axis 23 can also be above or below the connecting line 25 in FIG. 2, so that the disk 2 in FIG. 2 can be higher or lower.
