Definitions

  • the invention relates to a device and a method for stretching a weft thread inserted into a shed, in particular for air jet looms.
  • weft threads are entered at high speeds in a shed. Due to the driving forces and due to the braking forces at the end of the weaving process, the weft threads are elastically stretched. Due to this elongation, the weft threads tend to jump back into the shed upon completion of the weft insertion and form loops or loops there. Such loops or loops mean weaving errors.
  • so-called stretching nozzles are arranged on the side opposite the entry side of the shed, which stretch with a stream of air the registered weft thread and keep stretched. This tensioning and stretching can be further supported by the fact that the so-called auxiliary blowing nozzles or relay nozzles remain switched on after the weft insertion for a certain period of time. In order to apply a sufficiently high force for the stretching, a relatively large length of weft thread must be taken up by the stretching nozzle. In addition, the air consumption of such a stretching nozzle is relatively high.
  • an air jet loom with a weft insertion device wherein the weft insertion device enters the weft thread via a weft insertion channel in the shed, the weft thread is supported in the shed over a plurality of juxtaposed Staffettendüsen to the catcher side, on the catch side a clamping device consisting of a Clamping and one or more guided transversely to the weft thread clamping threads, is arranged, which clamps the weft thread end during the Abbindevorganges, and in the weft direction before the clamping device a stretching device is arranged outside the reed, which stretches the weft thread defined in the clamping device to form a weft thread loop and with it.
  • the invention has for its object to provide an improved device for straightening a registered weft thread.
  • This object is achieved in that on the side opposite the entry side of a shed an operable by means of a control thread clamp for clamping the weft yarn is provided in front of - as seen in weft transport direction - an operable by means of a control device for deflecting the weft thread, and the Device for deflecting as actuating device includes at least one pneumatic piston-cylinder unit.
  • the thread clamp and the device for deflecting on the same side i. are arranged on the entry side opposite side of a shed. Otherwise the risk of loops or loops being created is particularly high on this side.
  • the thread clamp prevents the registered weft thread springs back into the shed. Since it will not be possible in most cases to clamp the weft exactly at the moment in which it has completed its insertion movement, but has not yet moved back again, the means for deflecting and tensioning is provided. This ensures that the weft is then held stretched when he should have moved back a bit. In this way it is achieved that the tension of the weft thread over the weaving width is substantially the same, so that a good fabric quality is obtained.
  • a device for detecting the movement of a weft thread is provided, the signal is converted into actuation signals for the thread clamp and the means for deflecting. Since differences in the entry movement of the weft threads can occur, it is advantageous if the operation of the thread clamp and the means for deflecting in response to the detected movement of the weft thread, since then a better timing is possible.
  • a detector of a Vorspultechniks that detects the number of withdrawn at a weft insertion turns of the weft.
  • the signal is triggered on the entry side, so that even at very high web speeds sufficient time remains to operate the thread brake and the device for deflecting in a timely manner.
  • the size of the deflection force of the device for deflecting the weft thread is adjustable, controllable or controllable.
  • This adaptation to weft threads with different materials is possible to stretch a weft sufficiently without tearing it.
  • the invention is provided in a further embodiment that the course of the deflection force during the deflection of the weft thread is adjustable. It can be done, for example, that are provided in a further embodiment of the invention, at least two independently operable devices for deflecting.
  • Independently actuatable means for deflecting may also be useful if the materials of two weft threads to be successively inserted are so different that a different deflection force makes sense for them and this different deflection force is not possible by changing the setting of the same device.
  • a method for stretching in which the weft thread is clamped at least approximately with the end of the entry on the opposite side of the entry side and then held by deflection stretched until it is struck, the weft thread with a piston Cylinder unit is deflected, which is controllable or regulated.
  • a weft thread 10 is withdrawn from a supply spool, not shown by means of a Vorspulsammlungs 11 and wound in several turns on a drum of this Vorspulauss.
  • the weft thread 10 is held in two main blowing nozzles 12, 13. Between the Vorspul réelle 11 and the Hauptblasdüsen 12, 13 a yarn brake 14 is arranged.
  • the weft thread is blown by means of the main blower nozzles 12, 13 in a shed, which is formed in the region of a reed 15 from warp threads, not shown.
  • the lamellae are provided in a known manner with a U-shaped recess which is open to the fabric edge of the fabric, not shown.
  • the transport of the weft thread 10 in the weft transport channel 16 is supported by Hilfsblasdüsen or Stafettendüsen 17, each of which directs a blast of air in the weft transport channel 16.
  • Weft threads usually consist of a relatively elastic material. Due to the high working speeds they are elastically stretched when entering into a shed and in particular when braking at the end of the weft insertion. This elastic elongation is the reason why a registered weft thread has the tendency to jump back into the interior of the shed, or into the interior of the weft transport channel 16. He then forms in this area loops, which lead to a weaving error.
  • a thread clamp 22 is provided which engages the registered weft thread 10 on the entry side opposite side of a shed and stuck. Since it is not ensured that the inserted weft thread is grasped in time, i. if it is still (sufficiently) stretched, on the side opposite the entry side of the shed the thread clamp 22 is preceded by a device 23 with which the weft thread 10 is deflected and thus tensioned.
  • the thread clamp 22 and the device 23 are designed and arranged so that they do not hinder the entry of a weft thread.
  • the control device 21 forms an actuating signal for the thread clamp 22 and the device 23 as a function of the detected movement of the weft thread 10 during entry. In order to have a sufficient time for the operation of the thread clamp 22 and the device 23, the movement of the weft thread 10 is detected on the entry side. In the embodiment, this is done by means of the detector 20, which counts the withdrawn during the weft insertion of the drum of the Vorspultechniks 11 turns.
  • the control device 21 forms the actuating signal for the thread clamp 22 and the device 23 in response to the signal, the penultimate withdrawn turn corresponds.
  • the beginning and the end of the operation of the yarn brake 22 and the device 23 can be adjusted via the control device 21 in order to adapt to the material of the weft threads and / or the type of fabric weave.
  • FIGS. 1 and 2 are provided as actuators for the thread clamp 22 and the device 23 pneumatic piston-cylinder units 24, 25, which have very short switching times, since between the beginning and end of pressing only relatively short periods of time are available which are on the order of 20 ms.
  • the piston-cylinder units 24, 25 of the embodiment are driven in both directions with compressed air, so that no return springs are present.
  • the beginning and end of the operation of the thread clamp 22 and the device 23 is determined by the control device 21, which controls the compressed air supply to the piston-cylinder units 24, 25 via solenoid valves 26, 27.
  • the solenoid valves 26, 27 are preferably 5/3-way valves.
  • compressed air source is a compressed air reservoir or compressed air tank 28, is stored in the compressed air at a relatively high pressure, for example 6 bar.
  • the piston-cylinder unit 24 of the thread clamp 22 is supplied directly with the high pressure via the valve 26, so that for the thread clamp 22 very short switching times can be achieved.
  • the piston-cylinder unit 25 of the device 23 for deflecting is subjected to a variable pressure. In this case, a pressure curve is sought, as shown for example in Fig. 5.
  • the piston-cylinder unit 25 of the device 23 is subjected to a high pressure in order to trigger the movement as quickly as possible. After that, the pressure is reduced to a lower value, so that the force is reduced, with which the weft thread 10 is kept taut.
  • the pressure profile shown in Fig. 5 is achieved in that the solenoid valve 27, a throttle valve 29 and a small reservoir 30 are connected upstream. As long as the solenoid valve 27 blocks the line in the extension direction to the piston-cylinder unit 25, a pressure builds up in the small reservoir 30, which essentially corresponds to the pressure in the compressed-air tank 28. If the solenoid valve 27 in the extension direction the connection to the piston-cylinder unit 25 ago, so this is briefly applied to the full pressure until the reservoir 30 is emptied so far that it is refilled with the throttled by the throttle valve 29 pressure. This results in the pressure curve shown in Fig.
  • the throttling of the throttle valve 29 is preferably adjustable via an input device and the control device 21 in order to adapt to different materials of the weft threads and / or also to different weave bindings.
  • the throttle position of the throttle valve 29 can also be adjusted, controlled or regulated during weaving.
  • the control device 21 is actuated by means of a solenoid valve 31 of the piston-cylinder unit 25 connects a second compressed air supply.
  • the designed as shut-off valve solenoid valve 31 is preceded by an adjustable throttle valve 32, which is set to a higher pressure value than the throttle valve 29.
  • the actuation of the solenoid valve 31 may by the controller 21 a predetermined setting of a time period or an angular position of the Main shaft of the loom done.
  • a position detector 33 is associated with the piston of the piston-cylinder unit 25 of the device 23, which outputs a signal depending on the position of the piston or in a predetermined position, the second pressure peak causes.
  • the beginning and the end of the actuation of the thread clamp 22 and the device 23 can take place in predetermined periods of time after the signal of the detector 20.
  • the beginning and the end of the pressing is also determined in dependence on the angular positions ⁇ of the main shaft of the loom, since the movement of the sley and thus of the reed 15 is associated with these angular positions.
  • the time span between the arrival of the weft thread at the weft detector 19 and the signal from the detector 20 can also be taken into account.
  • the elements of the thread clamp 22 and the device 23 are arranged on the batten of the loom, which carries the reed 15. The arrangement is made so that all elements are in the rest position outside the contour of the weft transport channel, as can be seen from Figure 6.
  • Fig. 2 there is a stationary clamping member 34 above the weft transport channel 16.
  • the piston-cylinder unit 24 is arranged below the weft transport channel so far that the outermost end of the piston 35 is in the rest position below the weft transport channel 16.
  • the piston-cylinder unit 25 is likewise arranged below the weft transport channel 16 such that the piston 36 is completely below the weft transport channel 16 in the rest position.
  • the device 23 includes two deflecting elements 37, 38, which are arranged above the weft transport channel 16.
  • the piston 36, together with the weft thread 10, can be moved into the region between the two deflection elements 37, 38, and takes the weft 10 with.
  • the deflection path of the weft thread 10 therefore corresponds to twice the travel of the piston 36.
  • the thread clamp 22 can be followed by another weft guard 39.
  • a stretching nozzle 40 may be arranged, which blows from a arranged below the weft transport channel 16 blowing a compressed air jet together with the end of the weft thread in a perpendicular to the weft transport channel 16 extending above the weft transport channel 16 arranged pipe.
  • the tube and the blow opening are aligned obliquely or parallel to the weft transport channel 16.
  • two means 23 and 23 'for deflecting the weft thread can be arranged one behind the other.
  • the device 23 'then also has a piston-cylinder unit 25', the piston between two stationary deflecting elements 37 and 37 'is movable upwards.
  • a second device 23 'for deflecting a registered weft thread can also be useful if the loom is running very fast and weft threads must be entered from very different material in a row.
  • the piston-cylinder unit 25 ' would have to be equipped with its own solenoid valve and its own pressure supply line, which can be controlled independently of the control device 21.
  • the device 23 can be provided as shown in Fig. 4.
  • the piston-cylinder unit 25 is with a fork-shaped piston 41 is provided, the two prongs between the deflecting elements 37 ', 37 and 38 are hineinbewegbar.
