Definitions

  • the invention relates to a thread monitor arrangement of a thread clamping device and a support profile on which the thread clamping device is arranged, wherein the support profile at least partially surrounds an interior in which the thread clamping device is arranged, wherein the support profile in cross section has a base and two legs extending from the base.
  • Such a thread monitor arrangement is known from GB 1 172 893 A.
  • warp beams or warp rolls in which a plurality of threads are wound side by side. From such warp beams, the so-called warp is pulled off during weaving or knitting.
  • the coils are arranged in a gate. Usually, a plurality of coils are arranged one above the other and a plurality of such groups of coils one behind the other.
  • V-gate An embodiment of such a gate is formed by a so-called V-gate.
  • the coils are placed on a plan, which has the shape of a V.
  • the threads are biased together via a pipe system and then guided individually through a thread monitor assembly.
  • the thread monitor assembly has a thread clamping device that holds the thread in the event of a fault, for example, when a thread breaks on the way to the warper or warp beam.
  • there is also a sensor on such a thread monitor arrangement which detects the presence of a thread. If several coils are arranged one above the other, then a corresponding number of thread monitor arrangements are arranged one above the other.
  • a support profile for this purpose, for example, has a rectangular or U-shape in cross section. Such a profile shape has a greater rigidity than, for example, a flat material.
  • the thread clamping device is attached to the support profile.
  • Such a design is known for example from DE 198 23 613.
  • the invention has for its object to facilitate at a less susceptible gate handling.
  • the thread monitor assembly is protected by the support profile. It is therefore less sensitive to contamination.
  • the risk that the operator injured on the thread monitor assembly is kept smaller. It is practically no longer possible that result in thread wraps around the thread clamping device.
  • the thread clamping device no longer bothers when replacing individual coils, which may be necessary if a coil is defective or empty.
  • the interior in the supporting profile thus gets an additional function. It not only serves to give the support profile a shape that leads to a higher rigidity. He now also serves to position the thread clamping device, so that the support profile provides protection for the thread clamping device.
  • the slot facilitates the insertion or threading of a thread in the thread monitor assembly. You no longer need an auxiliary tool, such as an eyelet on a handle, which leads first through the thread clamping device, then inserts the thread and then pulls the eyelet back. You can thread the thread with a predetermined length directly through the slot Lead in the base and then insert in the thread clamping device. Since the slot continues at least in one leg, but usually also in both, you can easily reach the thread clamping device even if it is located in the middle of the support profile. Such a slot is dimensioned so that it does not unduly weaken the support profile, that is, the remaining portions of the legs are sufficient to support the thread clamping devices, which are arranged on the support profile, to a sufficient extent.
  • the thread clamping device preferably has a stationary first clamping element attached to the carrier profile and a movable second clamping element fastened to a cover protection which at least partially covers the interior.
  • the thread clamping device is then able to generate or release a force acting on the thread by displacing the two clamping elements holding force.
  • the cover protector, to which the second clamping element is attached then has two functions. He covers on the one hand the interior, so that the risk of contamination of the interior is kept small. On the other hand, it also serves to support the clamping element. The cover thus has an additional hold function. As a result, the assembly of the thread clamping device is facilitated. You can set the first clamping element on the support section and the second element on the cover. By mounting the cover protector on the support profile the thread clamping device is then simultaneously assembled.
  • the cover protection against the support profile is displaced.
  • the cover protection gets so then a third function. It serves to displace the second clamping element relative to the first clamping element.
  • the action of the clamping device can be changed to the thread.
  • the two clamping elements are moved together, then the thread is held.
  • the two clamping elements are moved apart, then the thread is released.
  • the second clamping elements of all thread clamping devices can be arranged on the same cover, so that you can activate or deactivate all thread clamping devices with a single displacement movement.
  • At least one of the clamping elements has a spring-mounted clamping surface.
  • At least one of the clamping elements is designed as a spring element, for example as a leaf spring.
  • a spring element for example as a leaf spring.
  • a leaf spring is a simple element that can be made from spring steel. When using a leaf spring, the thread clamping device is very inexpensive.
  • the cover protector preferably has a controllable displacement drive. About this displacement drive can then control the thread clamping device. When using a spring-mounted clamping element, the thread clamping device can not only turn on and off. The controllable displacement drive can also adjust the thread tension.
  • the displacement drive has a deflection gear, with which it acts on the cover. So you do not have to arrange the displacement drive in the continuation of the cover, but can move him laterally. This measure ensures that the height of the gate does not have to be increased.
  • the cover is guided in the support profile.
  • the support profile thus ensures that the cover always has a predetermined orientation. With this orientation it is ensured that the two clamping elements of the thread clamping device can cooperate in the desired manner.
  • a yarn guide eyelet is arranged in front of and / or behind the thread clamping device in the thread running direction.
  • a thread guide eye for example be formed of ceramic. It ensures that the thread is always guided along a predetermined path when passing through the thread clamping device, so that a wear of the thread clamping device is prevented. It is ensured that the thread can not cut into any surfaces of the thread clamping device.
  • a thread sensor is arranged in the region of the thread clamping device.
  • the yarn sensor detects the presence of a thread and triggers, for example, the thread clamping device, if it is determined that the thread tension has dropped at the exit of the thread clamping device.
  • the support profile is attached to a gate frame, wherein the base of the support profile includes a predetermined acute angle with a longitudinal direction of the gate frame.
  • the gate frame ensures that one can use a variety of support profiles, each of which in turn carries a plurality of thread clamping devices.
  • the individual support profiles are held by the gate frame in a predetermined position to each other. Now, if one arranges the base of the carrier profile not parallel to the gate frame, but rotated by a few degrees, then the respective thread can be better introduced over the profile edge in the above-mentioned slot in the base.
  • Fig. 1 shows a gate arrangement 1, which is formed as a V-gate.
  • the gate assembly 1 serves to support a plurality of coils 2. From the coils 2 threads 3 are withdrawn and fed to a warping or labeling system 4. In plan view, the coils 2 are arranged along the legs of a V. At each position, where in Fig. 1, a coil 2 can be seen, a plurality of coils 2 can be arranged one above the other.
  • Each coil is associated with a thread monitor assembly 5, which is explained in more detail with reference to FIG. 2.
  • the thread monitor assembly 5 initially has a support profile 6, which has a U-shape in cross section.
  • the support section 6 thus has a base 7, depart from the two legs 8, 9.
  • the two legs 8, 9 are arranged at a right angle to the base 7. This is not mandatory.
  • the support profile 6 surrounds an interior 10 on three sides. On the base 7 opposite side of the interior 10 is covered by a cover 11.
  • the cover 11 may extend not only, as shown, over part of the length of the support profile 6, but also over its entire length.
  • the cover protector 11 has laterally projecting lugs 12 which are guided in guide slots 13 of the legs 8, 9 are.
  • the guide slots 13 are adjacent to the open side of the U.
  • the cover 11 is displaced in the direction of a double arrow 14 relative to the support section 6.
  • a toggle 15 is provided, which engages with a lever arm 16 in an opening 17 in the cover 11.
  • the cover protector 11 is raised or lowered.
  • a second lever arm 19 is provided, which can be moved in the direction of a double arrow 20, that is perpendicular to the base 7.
  • a non-illustrated drive is provided, for example, as a piston Cylinder arrangement can be executed.
  • the thread monitor arrangement has a thread clamping device 21, which is arranged in the space enclosed by the support profile 6 and the cover 11 11 cavity.
  • the thread clamping device 21 has a first clamping element 22 which is fixed to the support profile 6.
  • the first clamping element 22 is thus arranged stationary. It is formed by a curved leaf spring.
  • the thread clamping device 21 has a second clamping element 23 which is secured to the cover 11, for example by means of a fastening arm 24 shown only schematically.
  • a fastening arm 24 shown only schematically.
  • the second clamping element 23 is formed as a leaf spring.
  • the formation of the two clamping elements 22, 23 as leaf springs has the advantage that you can adjust the clamping force with which the thread 3 between the two clamping elements 22, 23, within certain limits. If the two clamping elements 22, 23 are moved against each other, then the clamping force increases with increasing movement of the cover 11 down. In the same way, one can gradually release the clamping force when the cover protector 11 is moved upwards with the second clamping element 23. This can avoid that at the moment of starting the warping or warping 4 abruptly collapses the thread tension. Rather, it is possible to reduce the thread tension gradually until the warping or warping system 4 has reached the desired operating speed.
  • yarn guide eyelets 26, 27 are arranged, which are formed of ceramic. This thread guide eyelets 26, 27 are therefore subject to little or no wear. They keep the thread 3 with the thread clamping device 21 open by both clamping elements 22, 23 away.
  • a thread sensor 28 is arranged, which reports whether a thread has been lost (thread breakage). If this is the case or the tension of the thread decreases, then the thread clamping device 21 is activated, ie the second clamping element 23 is moved against the first clamping element 22 and holds the thread firmly.
  • not only the thread guides 26, 27 have a slot 29.
  • the base 7 of the support profile 6 has a slot 30 which continues over a small distance in the two legs 8, 9. The slot can pass in the legs 8, 9 in a circular opening, which then coincides with the opening of the yarn guide 26, 27 or larger.
  • the thread monitor assembly 5 is arranged so that its base 6 is not arranged at a right angle, but at an acute angle to the longitudinal direction of a gate frame 31. This facilitates the insertion of the thread over the edge of the profile 6 in the slot 30.
  • the threads 3 are guided from the spools 2 through the slot 30 into the yarn guides 26, 27 and the yarn sensor 28. They automatically get into the thread clamping device 21, which is open for the purpose of introducing the threads 3 or only acts with a low tension on the threads.
  • the threads 3 are then fixed in the warping or warping 4, for example on a warping drum.
  • the thread clamping devices 21 are moved together, so that they exert a relatively large clamping force on the threads 3. With increasing speed of the warping or warping system 4, the force exerted on the threads 3 clamping force is withdrawn and thus lowered the thread tension. This can be easy Way done on the control of the position of the cover 11.
