Definitions

  • the invention relates to a weaving machine with an entry system for a plurality of usually different weft threads according to the Preamble of claim 1.
  • each weft thread at least one thread supply, a thread store with integrated brake on the thread take-off side e.g. in form of Brush ring, a thread monitor, a thread brake, and one Include thread feeder as part of a color picker and a gripper.
  • the Weft threads run from the thread supply through the thread store, the Thread monitor, the thread brake and the thread feeder either in that Fabric in which the weft thread is bound or in a Thread clamp in which the weft thread is held.
  • the weft thread is inserted into the career of the Relocated and picked up by the gripper.
  • the involved Weft thread is cut off and inserted into the open shed.
  • the pinched weft thread is inserted and struck as well as after cut off the nip.
  • a disadvantage of this registration system is that for everyone Weft thread a thread monitor and at least one thread brake is provided, in which the drawn weft always remains.
  • the thread brake is soiled by the abrasion, so that the Thread brake must be cleaned periodically to prevent thread breaks avoid.
  • the invention has for its object a weaving machine with a to create a simplified and reliable registration system.
  • a thread store In the entry system with a thread supply, a thread store, a color selector and a gripper run out the weft threads from the thread supply to the thread store and the thread feeder of the Color picker in the fabric.
  • a thread guide between thread store and color selector, so that only one friction point formed by the thread feeder is present.
  • the color picker puts a weft thread in front of the hook using a thread feeder, which takes over the weft and enters it in the open shed. It only a thread brake is provided to the submitted Brake weft. Because every weft thread goes into the thread brake the thread brake cleans itself.
  • FIGS. 1 and 2 show one Execution of a registration system with e.g. four weft threads with e.g. different color or thickness and / or structure can be entered.
  • the entry system contains a supply spool 2 for each weft thread 1, a thread store 3 with an integrated brake on the thread take-off side e.g.
  • Thread feeder 5 in the form of a brush ring and a color picker 4 with four Thread feeder 5 and for all four weft threads together Guide organs 6 for calming the weft thread, which in Area of action of the thread feeder 5 are arranged as well Thread brake 7, a sensor 8, with which the thread tension is measured and the weft thread to be entered is monitored and one Thread monitor 9 for detecting an unintentional double shot, which are arranged after the color selector 4 in the running direction of the thread and a gripper 10.
  • the supply spools 2, the thread storage 3 and the Color pickers 4 are arranged in a known manner on the weaving machine.
  • the Guide elements 6, the thread brake 7, the sensor 8 and the thread monitor 9 are arranged on a guide part 11 for the gripper.
  • the Guide elements 6 are designed as pins.
  • the thread feeder 5, the Thread brake 7, the sensor 8 and the thread monitor 9 are with a Control device (not shown) of the weaving machine transmitting signals connected to control the entry.
  • the weft threads 1 are in a stop position (Fig.1), starting from the thread storage 3 via the Thread runners 4 run into the fabric 11 and outside the track of the gripper are held.
  • the entry is based on a control command the corresponding thread feeder 4 the one to be entered in the shed Move the weft thread from the holding position to a transfer position. In this transfer position, the weft thread 1 crosses the career of Gripper.
  • the weft thread is passed to the guide members 6 designed to calm the weft. While moving into that by the warp threads 12 formed shed 14 takes the gripper with his Thread clamp 15 on the weft thread.
  • the im Tied weft in the nip of the thread clamp inserted so that the weft thread is held in the thread clamp (Fig.2).
  • the weft thread is scanned and on the other hand the Weft thread drawn into the brake gap of the thread brake 7. Then the weft thread in the area of the fabric edge cut a cutter.
  • the weft is with the sensor 8 brought into contact with the course of the thread tension to measure during the insertion of the weft thread and if necessary in the same or a subsequent entry cycle if necessary change and monitor the weft to, for example, a Detect thread breakage and to give a loom stop signal.
  • FIG. 3 differs from the embodiment Fig.1 characterized in that in addition to the first thread brake 7, a second Thread brake 21 is provided, e.g. to increase the braking effect.
  • This thread brake is provided with a guide bracket 22 to the to insert the weft thread to be submitted securely into the thread brake 21. It it is pointed out that only the second thread brake is provided can be.
  • FIGS. 4 shows a third embodiment of an entry system. This Execution differs from that of FIGS. 1 and 2 in that the Thread brake 7 is arranged on the sley.
  • the advantage of this solution is that the effect of the thread brake up to the time of Leaf stroke is maintained.
  • This thread brake 25 is made up of two brake pins 26 and the respective one Thread feeder 5 is formed, which presents a selected weft thread.
  • This version represents the simplest solution with which, in addition to the submission function, the braking function is executable. The Size of the loop and therefore the braking effect on the measure of Draft of the thread feeder controllable in relation to the brake pins.
  • FIG. 6 shows a modified version of the thread brake according to FIG. 5.
  • the thread brake 27 contains two fixed brackets 28 which are spaced apart are mounted to each other on the guide part 11 for the gripper and a linear movable bracket 29, which is connected to an actuator 30 and relative to the fixed bracket 28 is adjustable. It goes without saying that also several both fixed and movable brackets are provided with e.g. the distribution of a reduced stroke.
  • the weaving machine contains a registration system for a plurality of in usually different weft threads, which for each weft thread a thread supply 2, a thread store 3 and a color selector 4 for optionally presenting the weft threads and a gripper 10 for insertion of the weft thread provided.
  • a registration system for a plurality of in usually different weft threads, which for each weft thread a thread supply 2, a thread store 3 and a color selector 4 for optionally presenting the weft threads and a gripper 10 for insertion of the weft thread provided.
