Definitions

  • the invention relates to a controllable device for feeding a clamped Weft to a rapier and the arrangement of necessarily at least a weft return device which interacts with the controllable device, the weft feeder and clamping device minimizing the Weft thread waste is used in the manufacture of fabric on rapier weaving machines and the at least one weft return device the weft in the feed phase tense.
  • each type of weft thread to be entered necessarily has a different waste length.
  • the thread clamp positioned closest to the fabric edge realizes a relatively small drop length
  • the weft thread drop of the weft threads, which are held by the other thread clamps is comparatively increasingly larger.
  • the increase in the length of the waste is device-related and, as already mentioned, a considerable disadvantage.
  • the device for carrying out the method should be briefly characterized. Thereafter, a device for the presentation and clamping of weft threads in a rapier weaving machine is known.
  • the device essentially comprises a feed lever with a thread clamp for each weft thread to be inserted into a shed.
  • the feed levers are arranged side by side and approximately parallel to the fabric edge on the entry side.
  • the clamp of the first feed lever is closest to the fabric edge in positions A and C, while the clamp of the last feed lever is positioned furthest away from the fabric edge.
  • a controllable weft clamping device with several clamping points is known, each clamping point being displaceable relative to a reference plane and furthermore the clamping points being arranged one above the other at constant intervals and one clamping point each being able to be moved into the reference plane.
  • controlled weft selector ie each clamping point of the controlled clamping device is assigned a controlled weft selector due to its function, it is advantageously achieved on the one hand that the weft to be entered into the shed can be moved into a first reference plane and in which it can be moved by the gripper is easily taken over.
  • the clamping point in question can be moved into a second reference plane, which corresponds to the position of the binding point of the tissue. It is hereby achieved that when the weft thread strikes the binding point of the fabric, the weft thread is picked up by the relevant clamping point of the clamping device and the weaving compartment on the insertion side is held taut between the fabric edge and the clamping point. This is advantageous for the cutting process of the thread scissors arranged between the clamping point and the fabric edge. A minimization of the weft thread waste cannot be achieved with this, however, because the weft threads cannot be presented to the rapier immediately.
  • EP 0 644 286 A1 which has also become known, discloses a controllable one Weft thread clamping device with several clamping points, their structure and function in is essentially disclosed by DE-OS 25 31 954.
  • a weft feeder and clamping device has a plurality of weft feeders with a clamp and is arranged in the weaving machine in combination with at least one weft return device and interacts so that all wefts to be entered in a loom in a predetermined sequence are designed based on the inventive design of the Weft feeder and clamping device and their arrangement in the weaving machine a minimum of weft waste is realized.
  • control engineering measures advantageously achieve that at least during the feeding of the relevant weft a retraction of the weft thread and thus a desired tension force can be generated in the weft thread for the rapier gripper, which is necessary in particular for the safe takeover of the weft thread by the rapier gripper.
  • FIG. 1 shows the structural structure of the device 6 according to the invention with a plurality of feed levers 15.
  • Each feed lever 15 has at its free end a clamp 16 for receiving the end of a weft thread 3 to be fed to a gripper 2, see also FIGS. 4, 5 and 9.
  • the other end of the feed lever 15 has, as shown in FIG. 1a, a through bore 15a in the direction of the longitudinal axis 15d, in which a groove 15b is formed over the length of the bore 15a, parallel to the longitudinal axis 15d.
  • a guide lug 15c extends at an angle to the groove 15b and also parallel to the longitudinal axis 15d.
  • a shaft 13 is received by a shaft 13 via the bore 15a in such a way that they can be displaced together on the circumference of the shaft 13 in the direction of the central axis 13a.
  • the shaft 13 is held between a first extension 11 and a second extension 12 of a carrier part 10 so as to be rotatable about its axis 13a.
  • the lugs 11 and 12 protrude at right angles from the support part 10 in the manner of a bracket.
  • the device 6 has a profile-like guide part 19, which according to FIG. 3 is provided with a longitudinal groove 20 running parallel to the central axis 13a of the shaft 13 and with a groove 21 running transversely to the longitudinal groove 20.
  • the groove 21 lies in a plane which is referred to as the reference plane 7.
  • the reference plane 7 is here the plane in which a rapier gripper 2 takes over the weft thread 3 supplied by a weft thread feeder and clamping lever 15 for entry into a shed 1. 2, a driver 14 is arranged on the shaft 13 in the reference plane 7.
  • a control program of the weaving machine according to FIG.
  • the drive transmission means is here, for example, a coupling gear, which is connected to a cam disk 31a of a machine-specific drive shaft 31.
  • the coupling gear 23 consists of a scanning roller 23a which is in a scanning connection with the cam disk 31a, the coupling joints 23b, 23c and the coupling rods 23d, 23e, 23f.
  • a spring element 32 which is fixed to the machine, ensures that the scanning roller 23a does not lift off the cam disk 31a rotating in the direction of the arrow 33.
  • the coupling gear 23 there may also be an electromotive drive which, according to FIG. 1, is connected directly to the actuating shaft 13 and rotates it in the direction of the double arrow 13b together with the relevant weft feed lever 15 about the central axis 13a.
  • the rotary movement lies within an angle of rotation lying between positions A and B.
  • FIG. 3 shows the guide part 19 designed in the manner of a profile with the longitudinal groove 20 and the transverse groove 21 extending from the longitudinal groove 20, which, as mentioned above, the Reference plane 7 for the weft threading to the gripper 2 is.
  • the nose 15c of the feed lever 15 concerned engages in the transverse groove 21 when the weft feed function is used.
  • the guide part 19 is connected to the carrier part 10 in a suitable manner and by suitable means.
  • FIG. 4 schematically shows the position of the weft feed lever 15 with the weft thread 3 held in the weft clamp 16 of each feed lever 15.
  • the feed levers 15 are positioned near a weft scissors 8 arranged on the left edge of a fabric 26.
  • each feed lever 15 between the rest position A and the working position B corresponds approximately to a weft length of at least 30 mm, which advantageously results in reduced waste per weft insertion.
  • FIG. 5 there is a feed lever 15 of the schematically represented device 6 in the working position B.
  • a weft selection needle 5a of the weft selection device 5 that has been moved from the rest position F.
  • the weft thread 3 is taken over in the working positions B and D by the gripper 2.
  • the rapier gripper 2 carries the weft thread 3 in the direction of the arrow 34 into an open shed 1 up to approximately the middle of the same, in which it is taken over by a slave rapier, not shown.
  • Figures 6 and 7 show a in the path S, see also Figure 5, the weft 3 between a thread storage and delivery device 4 and the weft selection device 5 weft retrieval device 9.
  • the retrieval of the relevant weft 3 is here in connection with the Feeding the weft thread through the relevant feed lever 15 to the rapier gripper 2 is a necessary prerequisite so that in every case the weft thread takeover by the rapier gripper 2 is a tensioned weft thread 3.
  • the return device 9 is designed as a pneumatically acting nozzle device and in Figure 7, the return device 9 is designed as an electromagnetically driven device.
  • the return device can also be designed as a weft winding or looping device driven by an electric motor.
  • the weft retrieval can be carried out by controlled movement of the relevant the weft 3 leading weft selector needle 5a done by the needle 5a in a Position E is moved, which is not the working and or advance position D of the needle 5a.
