Definitions

  • the invention relates to a device for monitoring the thread travel on a bobbin creel, in particular on a slip creel according to the preamble of claim 1.
  • Such devices have the task of imparting a certain thread tension to the threads drawn from the bobbin creel, but also reducing the thread tension, e.g. in the event of a thread break and to determine when the machine comes to a standstill to clamp the threads to prevent them from running on.
  • Comparable devices were used in particular in the case of V-shaped slip gates in which the threads are deflected in the direction of the winding device directly at the guard needle.
  • EP-A-311 781 Devices of comparable generic type are described, for example, in US Pat. No. 4,598,184 or in EP-A-311 781.
  • the clamping devices have always been subjected to constant pressure, with each thread quality being clamped with the same clamping force.
  • EP-A-311 781 the spring device is provided with an additional control spring which allows the clamping jaw to be relieved.
  • EP-A-311 781 the spring device is provided with an additional control spring which allows the clamping jaw to be relieved.
  • such a relief is only possible within a whole vertical row of clamping devices, since the relief takes place via the vertical control rod for opening and closing the clamping jaws.
  • an individual adjustment of the spring force on each individual clamping device is not possible.
  • the clamping force can be adapted to the thread quality, regardless of the position of the respective winding point in the creel. So far, it has been common to install springs of different strengths in the clamping devices, but this required complex disassembly.
  • This object is achieved according to the invention with a device which has the features in claim 1.
  • the adjusting device assigned to each clamping device allows the spring force on the spring device to be adapted to the individual circumstances in the simplest way.
  • the spring device is particularly advantageously designed as a compression spring which is mounted on a pressure pin connected to the clamping jaw, the pressure pin cooperating at its end with a guide link and being able to be pressed against the spring force in the open position and the abutment of the compression spring being adjustable on the pressure pin is trained.
  • the displaceable abutment allows the compression spring to be tensioned or relaxed in the simplest way.
  • the abutment can be adjusted particularly advantageously with a linearly displaceable slide which has a guide link.
  • the setting device could practically only consist of this slide, which can be set manually, for example.
  • a particularly advantageous actuation of the slide can also be achieved with a pivotally mounted adjusting lever which engages with a sliding joint in the slide at its free end.
  • the setting lever can be turned with a screwdriver, for example.
  • this can be fixed by a cover plate, which at the same time also covers the clamping device and the adjusting device and thus protects against dust and fibers.
  • the cover plate can have an opening with a Have mark at which the set position of the adjusting lever can be read. Securing the setting once selected with the cover plate has the advantage that this setting is not lost due to improper manipulation.
  • the cover plates would have to be loosened, which may only be done by authorized personnel.
  • a particularly great flexibility of the device results when the needle of the thread monitor is also pretensioned with a tension spring, the bearing point of which on the frame is adjustable for changing the tensile force.
  • the thread tension or the reaction time of the guard needle can also be adapted to the drawn threads within certain limits.
  • the tension spring can also be attached to a pivotably mounted adjusting lever.
  • Clamping device and thread monitor do not necessarily have to be arranged together within a bobbin creel.
  • the clamping device and the thread monitor form a structural unit with a common base plate and if the adjusting lever for the clamping device and the adjusting lever for the thread monitor can be fixed with a common cover plate.
  • the setting for the spring force acting on the guard needle can also be secured in the same way, with a corresponding opening in the cover plate and a marking also making it possible to read the setting from the outside.
  • the device consists of a unit in which the clamping device 1 and the thread monitor 2 are arranged on a common base plate 7.
  • This base plate is fixed to the vertical U-profile 30, which is arranged in front of each vertical row of winding units on the gate.
  • the thread 3 comes from the thread spool, not shown, between a movable jaw 5 and a rigid clamping rib 8 and is deflected at the guard needle 32, where it runs in the direction of arrow a against the winding device.
  • the clamping jaw 5 has a hub 11, in which a pressure pin 6 is fastened with the aid of a securing pin 12. At its free end, this pressure pin has a rounded head 9 which is enlarged in diameter and which cooperates with a guide link 25 on a vertical control rod 24.
  • the pressure pin 6 is guided on the one hand in a bore 13 in the clamping rib 8 and on the other hand in a bore 15 in the base plate 7 in such a way that the clamping jaw 5 can be moved plane-parallel to the clamping rib 8.
  • the clamping jaw 5 is pressed against the clamping rib 8 with the aid of a compression spring 4. This compression spring is supported on the enlarged head 9 and lies on a washer 10 serving as an abutment.
  • a slide 17 is arranged, which can be moved linearly and approximately at right angles to the pressure pin 6.
  • the slide has a slot 18, which allows the pressure pin 6 to overlap in any relative position. While the slide is flat on the side of the clamping rib 8, it has a guide link 19 on the opposite side, on which the washer 10 can slide. In its upper area, the slide is provided with a horizontal groove 20.
  • the slide is actuated by means of an adjusting lever 21. This is rotatably mounted on the base plate 7 and has a slot 23 into which a screwdriver can be inserted.
  • a cam 22 at the free end of the adjusting lever forms, together with the groove 20 in the slide 17, a thrust joint, with the aid of which the rotary movement is converted into a thrust movement.
  • the thread monitor 2 has the monitor needle 32 already briefly mentioned, which is, however, only indicated in FIG. 1.
  • This guard needle has a hook-shaped end and is pivotally mounted on a joint 34.
  • the watchdog needle is designed as a double lever, a tension spring 35 being attached to the lever arm 33, which provides the watchdog needle with a specific torque.
  • the opposite end of the tension spring 35 is suspended on a rotatably mounted adjusting lever 36, which is also provided with a slot 39 for rotation.
  • the end of the lever arm 33 also interacts with a switching device 37, which triggers a switching operation for stopping the machine and activating the clamping device 1 at a certain lever position.
  • the base plate 7 is at three different locations with threaded holes 16 provided. These holes are used to fasten a cover plate 26, as can be seen from FIG. 3. This cover plate can be screwed against the base plate 7 using screws 27.
  • the two adjusting levers 21 and 36 are arranged in the plane of the base plate in such a way that they can no longer pivot when the cover plate is screwed on. However, openings 28 and 40 are arranged in the cover plate through which the position of the adjusting levers can be viewed. Markings 29 and 38 on the cover plate also allow the selected setting to be read.
  • the cover plate 26 is laterally provided with a wing 43 which projects beyond the U-profile 30.
  • a hook-shaped slot 31 is arranged through which the thread can be inserted.
  • An upper rib 41 runs along this slot, which also serves as a catch bearing for the guard needle 32 in a lowered position in the event of a thread break. This position is indicated in FIG. 3 by dash-dotted lines.
  • a lower rib 42 on the cover plate serves as a rear boundary for the guard needle 32 with normal thread tension in the operating position.
  • the watchdog needle can be unhooked from the joint 34 in the simplest way by means of a bayonet lock, which is not shown here.
  • FIG. 4 again shows the device according to FIG. 1 with the same basic setting of the spring device, but with the clamping jaw closed.
  • This position is reached when the machine is at a standstill, which can be triggered, for example, by a thread break. If the thread tension suddenly decreases, the tension spring 35 pulls the lever arm 33 in the direction of the arrow b upwards, the guard needle 32 being pivoted in the direction of the arrow c.
  • the activated switching device 37 switches off the winding machine and simultaneously activates the control rod 24, which is moved in the direction of arrow d with the aid of a drive device, not shown.
  • the guide link 25 releases the pressure pin 6, which is moved under the tension of the pressure spring 4 in the direction of arrow e.
  • the clamping jaw 5 is pressed against the clamping rib 8, wherein the thread is prevented from running on and is kept taut.
  • FIG. 5 shows the device again with the jaw 5 closed or with the guard pin 32 lowered.
  • the different setting of the two setting levers can be read on the scale on the cover plate 26. Of course, depending on the individual case, only one of the two settings can be changed.
