Definitions

  • the invention relates to a compensation thread tensioner with a thread inlet, a thread spout, a compensation device between the thread inlet and the thread outlet, which is movable against a compensating force by a thread running from the thread inlet to the thread outlet thread and thereby changes their engagement geometry with the thread, and a reassurance between the thread inlet and the compensation means comprising two contiguous pacers between which the thread passes.
  • the invention relates to a gate with such a compensation thread tensioner.
  • the invention will be described below in connection with the warp preparation. However, it is not limited to this, but applicable everywhere where Thread is withdrawn from a spool and should be kept under a predetermined and uniform as possible voltage.
  • warp preparation many threads are simultaneously deducted from a corresponding number of coils, which are arranged in a gate. These many threads are then wound simultaneously on a warping drum, for example, the warping drum of a cone warping machine.
  • a thread tensioner for each thread. There are different designs for this.
  • the present invention is concerned with a so-called compensation thread tensioner.
  • a compensation thread tensioner acts on a compensation device in one direction a compensation force and in the other direction of the force acting on the thread train, so the thread tension.
  • the compensation device changes during its movement their engagement geometry with the thread and thus also the frictional engagement between the thread and the compensation device. If the tension in the thread becomes too great, the friction is reduced so that the thread tension decreases again. If, on the other hand, the thread tension becomes too small, then the friction is increased, so that the thread tension increases again. With this procedure, it is true that an absolutely constant thread tension can not be obtained. However, the thread tension fluctuations are within a tolerable range.
  • This calming device consists in the simplest case of two calming elements which abut each other. If the thread passes between the two calming elements, for example plate-like or plate-like elements, then it raises these two calming elements slightly apart. The pressure exerted by the two calming elements on the thread, but sufficient in many cases, to lead to a sufficient calming of the vibrations.
  • the invention has for its object to keep the yarn tension as evenly as possible.
  • the reassurance element is moved relative to the yarn and in a direction that does not coincide with the direction of movement of the yarn, at least in the contact region between the reassurance element and the thread.
  • the changes in yarn tension are due to the fact that the frictional conditions that affect frictional engagement between the yarn and the compensator are influenced by deposits that transfer from the yarn to the settlers. Such a deposit, such as a wear Avivagen, is then taken from time to time by the thread and transported to the compensation device. There it changes the frictional engagement, so that the desired uniformity in the thread tension can no longer be maintained.
  • the movement drive is designed as a rotary drive.
  • This is a relatively simple embodiment of the motion drive.
  • the motion drive puts the calming element in rotation. This rotation can be alternating in two directions of rotation. In a preferred embodiment, however, a single direction of movement is maintained, so that the reassurance element rotates continuously.
  • a calming element is adjacent to a base of the compensation thread tensioner and this calming element comprises the movement drive. You can then use the base of the compensation thread tensioner to accommodate the rotary drive. The transmission of drive energy from the motion drive to the reassurance element is not disturbed by the thread.
  • one of the calming elements is arranged at the bottom in the direction of gravity, and this calming element is connected to the movement drive.
  • this calming element is connected to the movement drive.
  • the movement drive preferably has an engine arranged on the compensation thread tensioner.
  • Such a motor does not have to provide greater drive power. He only has to be able to move the reassuring element associated with him, in particular to turn. Accordingly, such a motor can build relatively small. It is only necessary to transmit a drive power, for example electrical voltage, to the compensation thread tensioner.
  • the movement drive has a transmission element which is accessible from the outside.
  • an external drive for example, a transmission device, a shaft, a chain drive, a V-belt or the like, and to drive the reassurance element from the outside. This has the particular advantage that you can supply multiple compensation thread tensioner with a single motor, so that the reassurance of all connected compensation thread tensioner can be moved.
  • the compensation device has at least one pin, wherein a contact angle between the thread and the pin can be changed by a movement of the compensation device.
  • the frictional connection Among other things, the angle between the thread and the pin depends on the contact angle, that is, on the wrap angle with which the thread bears against the pin. This wrap angle will usually be significantly less than 180 °. For this reason, the term "contact angle” is preferably used instead of the term "wrap angle”.
  • the frictional engagement between the thread and the pin is determined by a non-rotatable pin according to the laws of rope friction. A non-rotatable pin is preferred here.
  • the pin is part of a group of three pins, over which the thread is U-shaped guidable. So you arrange the three pins so that a pin between the other two pins is arranged. Now, if the two pins on the one hand and a pen on the other hand can be moved relative to each other, then the thread is pulled more or less far into the U. Accordingly, the contact angle between the pins and the thread increases or decreases.
  • the object is achieved in a gate of the type mentioned above by using a compensation thread tensioner of the type described.
  • a plurality of compensation thread tensioners have a common movement drive. Accordingly, one saves, for example, a separate motor for each compensation thread tensioner.
  • a compensation thread tensioner 1 has a base 2 on which the parts described below are arranged.
  • the base 2 can be fixed with a clamping device 3 in a gate, not shown. Appropriately, each coil position in the gate associated with such a compensation thread tensioner.
  • the compensation thread tensioner 1 has a thread inlet 4 formed by an eyelet, for example, and a thread outlet 5 also formed by an eyelet, for example. Other configurations for thread inlet and thread outlet are possible.
  • the compensation device 6 has a lever 7 which can be pivoted about a pivot point 8.
  • the lever 7 is under the action of a spring 9, the force of which can be changed by an adjusting device 10.
  • the spring 9 tries to rotate the lever 7 clockwise about the pivot point 8.
  • the train of the thread 11 tries to pivot the lever 7 in a counterclockwise direction against the force of the spring 9 about the pivot point 8.
  • a pin 13 is arranged, which can be performed at a pivoting movement of the lever 7 about the pivot point 8 between two pins 14, 15, which are fixed to the base 7.
  • two pins 16, 17 are fixed to the lever 7, which can be guided past a pin 18 which is fixed to the base 2, when the lever is pivoted clockwise.
  • the calming device 19 has, as in Fig. 2 can be seen, a lower calming element 20 and an upper calming element 21.
  • the two calming elements 20, 21 are under the action of gravity to each other.
  • the thread 11 is guided between the two calming elements 20, 21 and lifts them apart, at least where the thread 11 runs along.
  • the two calming elements 20, 21 are formed as plates, which are each provided with a bevel 22 on their mutually facing edge regions in order to facilitate the threading of the thread 11.
  • the two calming elements 20, 21 are rotatably mounted on a common axis 23. An upward movement is limited by a stop 24.
  • the stopper 24 is as shown in Fig. 1 can be seen, laterally adjacent to the calming elements 20, 21 connected by a screw 25 to the base 2.
  • the stopper 24 simultaneously carries the axis 23rd
  • the carrier 26 is non-rotatably connected to a gear 28 which is in engagement with a further gear 29 which is driven by a motor 30 shown only schematically.
  • the gear 28 is arranged at a different position and with a drive shaft 31 is engaged, which is accessible from the outside.
  • the two settling elements 20, 21 rotate about the axis 23. This rotation takes place directly for the lower settling element 20 by the drive 30, 31.
  • the upper calming element 21 is entrained by friction from the lower calming element 20.
  • a common motion drive for a plurality of compensation thread tensioners 1 on a gate. Also, such a common motion drive can be dimensioned with a relatively low power, since the moment necessary to drive a single reassurance means 20 is comparatively small.
