Definitions

  • the present invention relates to a method for controlling a thread store according to the preamble of claim 1 and a spinning device according to the preamble of claim 3.
  • a thread store according to the preamble of claim 1
  • a spinning device according to the preamble of claim 3.
  • the thread supplied at constant speed is not included constant speed from the winding device can be wound onto a package.
  • this is due to the fact that conical coils rotate at a constant speed but, due to their conicity, have different circumferential lengths. If the thread is laid in the area of the smaller diameter of the conical bobbin, a smaller amount of thread is wound up than if the thread guide deposits the thread in the area of the large diameter of the conical bobbin.
  • the prior art has proposed using thread stores which ensure that the thread which is currently unwindable is temporarily stored, this thread store being filled to the maximum when the thread guide passes the thread in the area of the small diameter of the conical bobbin, while the thread store stores the smallest thread loop when the thread guide deposits in the area of the large diameter of the conical bobbin.
  • the thread stores are pivotable levers which are positively controlled depending on the movement of the thread guide.
  • a traversing rod extending over the spinning machine is provided. From the thread storage device, the thread is formed into a loop transverse to its direction of travel, which is made larger or smaller as required by the pivotable lever.
  • a winding device for conical cross-wound bobbins in which a thread store is provided for receiving the temporarily excess thread, which is designed as a spring-loaded dancer arm that deflects the thread transversely to the thread running direction and holds it under tension. Due to the spring 35, the size of the thread loop automatically becomes larger when more thread is delivered than is wound up. Conversely, the thread store is able to dispense the thread again if necessary. The thread loop is not positively controlled.
  • a similar thread store is known from the RU 14 rotor spinning machine from Schubert & Salzer Maschinenfabrik Aktiengesellschaft in D 8070 Ingolstadt, in which the dancer arm deflects the thread transverse to the bobbin axis towards the inside of the machine.
  • the force of the spring acting on the dancer arm can be changed by means of an adjusting device, so that bobbins with different thread tension can be produced at the winding point.
  • Such thread stores are used not only for the winding of conical bobbins, but also if, for example, the thread is waxed at the same time during winding. The resulting irregularities in the thread tension are corrected by the thread store.
  • the known thread stores have the disadvantage that when the thread tension changes or the thread loop is reduced beyond the working area of the dancer arm, contact between the dancer arm and the thread is not always guaranteed. If the dancer arm is quickly brought in the direction of its end position of the working area when the thread tension rises, it happens that the dancer arm detaches from the thread and then, due to the spring, is suddenly returned to it. This can lead to thread breaks.
  • the inventive design of the spinning device or its thread storage means that when tension peaks occur in the yarn during the thread storage is maximum, these do not lead to thread breaks.
  • the dancer arm is not lifted by the stretching thread, but remains in constant contact with it. Additional stresses on the thread due to the dancer arm striking back on the thread can thereby be avoided.
  • a stop is provided against which the dancer arm strikes before it leaves its normal working range. This stop is particularly easy to attach an additional elastic element, which then transmits its force to the dancer arm. It is particularly advantageous if the force of the additional elastic element is significant is larger than that of the first elastic member. This ensures that the tension peaks of the yarn can be intercepted.
  • the dancer arm has an extension which extends beyond its pivot point and with which it cooperates with the stop and the additional elastic element.
  • an automatic maintenance device of a spinning machine can move the dancer arm on this extension. This is necessary, for example, when spinning on an open-end spinning machine.
  • the dancer arm can be placed on the thread in a precisely controlled manner.
  • the first elastic element is fastened via a swivel arm. The pretension of the first elastic element is changed by pivoting the swivel arm. This makes it possible to adjust the tension of the thread with which it is to be wound onto the bobbin.
  • the invention is particularly advantageous when the swivel arms are connected, for example, to a machine side or to several winding stations on the spinning device via a control rod. This makes it possible to set the thread tension simultaneously on all or more winding positions. It's just that necessary to adjust the control rod, for example on the machine end frame.
  • the thread store is designed such that the dancer arm executes its movement in a plane that is horizontal.
  • the effect of this is that gravity influences on the dancer arm are avoided, as a result of which the thread tension of the thread to be wound can be kept better constant.
  • This arrangement of the dancer arm only has to be moved against its inertia. Movement against gravity, e.g. by lifting the center of gravity with a dancer arm moving in a vertical plane, is eliminated.
  • the thread store 1 has a dancer arm 11 which is rotatably mounted on a base body 2.
  • a swivel arm 3 is rotatably attached to the base body 2.
  • An elastic element 12 is stretched from the swivel arm 3 to the dancer arm 11, by means of which a force is exerted on the dancer arm 11 which allows it to form a yarn loop against the tension of the yarn.
  • the swivel arm 3 has a groove 31 into which a control pin 71 of the control rod 7 engages (cf. FIG. 3).
  • the stop 4 is rotatably mounted on the base body 2 and is held in its basic position shown in FIG. 1 by means of the additional elastic element 41.
  • the dancer arm 11 has an extension 13 with which it rests in the illustration of FIG.
  • the dancer arm 11 of Figure 1 is shown in one end position within its working area. This is the position in which it is deflected most without the force of the additional elastic element 41 already being applied to it.
  • the yarn loop is formed or enlarged by the dancer arm 11 by pivoting to the right in the direction of arrow P when viewed in FIG. 1.
  • the force that the first elastic element 12 exerts on it becomes smaller since it is a spring with a spring constant.
  • the thread does not run over rollers, but is guided through the hook 14 of the dancer arm 11. If the situation arises that the tension of the thread increases, although the dancer arm 11 is already in its end position shown in FIG.
  • the extension 13 makes it possible in a simple manner for an automatic maintenance device to pivot the dancer arm 11 into a desired position. For example, in the case of open-end devices, it is necessary for the dancer arm 11 to be pivoted further against the direction of the arrow P during the piecing process. This is necessary in order to be able to return the thread for piecing.
  • the extension 13 enables simple control of the dancer arm by a maintenance device, because the extension 13 can be pressed in a simple manner, for example by a rod, in the direction of the swivel arm 3.
  • a control pin 71 (see also FIG. 3) is moved in the direction of the arrow F.
  • the swivel arm 3 rotates to the right or to the left, as a result of which the spring 12 is rotated accordingly.
  • Swivel arm 3 is rotatable about the mounting 32 mounted. The thread tension of the wound thread can thus be adjusted in a simple manner.
  • FIG. 2 shows a side view of the thread store 1 from FIG. 1.
  • FIG. 3 shows two thread stores 1 mounted in the spinning device 8, from which parts of the machine frame 81 are visible.
  • the control rod 7 is also mounted on the machine frame 81 and is used to adjust the preload of the spring 12.
  • the thread store A in the image of FIG. 3 below, is a thread store, the swivel arm 3 of which is similar Position is like that of Figure 1.
  • the spring 12 is only slightly tensioned. By moving the control rod 7 in Figure 3, A in the direction of arrow G, the pivot arm 3 is placed in the position shown in Figure 3B. In this position, the spring 12 is maximally biased.
  • the pivoting of the swivel arm 3 takes place in that the control pin is moved in the groove 31 of the swivel arm 3, the control pin 71 being movable only in the direction of arrow G and in the opposite direction. Because it cannot perform any transverse movements, the swivel arm 3 is forced to swivel its attachment 3, which results in a greater or lesser tension in the spring 13.
  • the control rod 7 can be designed so that it is guided along an entire machine side, so that all thread stores connected to it can be changed in the bias of their spring 12 at the same time.
  • the thread stores are arranged in the spinning device 8 so that their dancer arms 11 execute their movement in a horizontal plane. With this arrangement, no influences of gravity are transmitted to the thread guided by the dancer arm. Due to the lightweight construction of the dancer arm 11, the influences on the thread, which arise due to the inertia of the dancer arm, are also very small.
