Definitions

  • the invention relates to a method according to the preamble of patent claim 1 and a thread delivery device according to the preamble of patent claim 14.
  • WO-A-92/04490 and EP-A-0 699 790 known method is formed on a storage body, a winding of adjacent or spaced turns.
  • the entry system pulls the thread from the roll over the front end of the storage body.
  • the windings on the storage body can be moved forward by different feed devices.
  • the storage body is axially longer than the winding. Pulling off creates a thread balloon that produces significant thread tension variations and significant thread tension that slows down the entry. In order to achieve high entry speeds, considerable energy expenditure in the entry system is required. Conversely, this means a high mechanical load for the weft.
  • the filament winding formed on the stationary support is constantly supported on the support from the inside, ie also during withdrawal after release of the stoppage element from its Intervention with the support.
  • the thread is pulled off from the foremost turn in the withdrawal direction and beyond the front end of the support.
  • considerable centrifugal forces act on the weft thread, which lead to an undesirable strong balloon effect.
  • the weft yarn lifts itself off the support and, in a free-flying spiral shape, looks for the way to extend the axis of the support.
  • the stop element is responsible for both initiating an entry and terminating it.
  • the weft thread is withdrawn from the rotationally driven measuring support via the forward end of the support in the withdrawal direction.
  • all formed turns of thread on the support are supported from the inside. It therefore creates an undesirable balloon effect.
  • a catching and releasing element designed as a catching needle is pivotally mounted in the interior of the rotationally driven measuring support, which is pushed cyclically outwards through a lift arranged in the drive shaft and pulled inwards. As soon as the catching needle has been pushed outwards between two turns of thread, it is moved in the drawing-off direction through the enlarging thread winding into the catching position defined in the measuring support.
  • the fishing pin is two-armed, so that one arm makes a sizing on every other trigger, while then the other arm by the force exerted on one arm adjustment the thread turns is moved back to the starting position.
  • a yarn feeding device with a rotationally driven support can no longer meet the requirements of modern weaving machines in terms of yarn speed and picking frequency due to the large moving masses.
  • the invention has for its object to provide a method and a yarn feeding device of the type mentioned, with which with low energy consumption, even with high performance of modern weaving machines with high reliability optimally short entry times are possible.
  • the winding section released from the support for withdrawal in ordered turns shows, among other things because of its inertial behavior and the dimensional stability of the turns, a tendency to remain in space essentially without any mechanical inner support in such a way that the weft thread first pulls off without any balloon formation inside and continues to run centrally out of the tube and the turns successively clean consumes, down to the last nachge deviste and possibly still supported on the support turn.
  • the released winding section does not collapse.
  • the turns do not tend to entangle or collapse, provided that the withdrawal is fast and accurate in time controlled tuning to the release of the winding section.
  • the method can be surprisingly short insertion times achieve, with which it is possible to optimally use the performance of modern weaving machines in terms of high thread speeds and high insertion frequencies.
  • the released thread winding section may be the released thread winding section from the outside if necessary. Be Supported. Such support But it is more a security measure.
  • the winding speed of the at least substantially continuous winding process is expediently matched to the insertion frequency and the length of the respectively inserted weft thread section such that each entry consumes the released winding section before the next following winding section is released. Even at extremely high yarn speeds, it is surprisingly evident that the centrally drawn weft yarn consumes the foremost turn in the withdrawal direction substantially radially inwards and without a balloon and the tubular configuration of the turns in the released winding section is maintained until the end of the entry with optimum thread geometry.
  • the released winding section may contain a number of turns of thread substantially corresponding to the weft length to be entered, or a larger number corresponding to a plurality of wefts to be inserted successively.
  • the turns in the winding section are released by overfilling the inner support beyond its discharge end.
  • the released turns are consumed in the deduction, before the released winding section could collapse or mess up.
  • the overfilling takes place by the continuous winding of the weft thread material.
  • the windings may be released by forward feeding of the roll on the support beyond its discharge end.
  • feed devices of any kind can be consulted.
  • the filament winding and its released part can be conveyed in the withdrawal direction obliquely upwards or upwards.
  • the procedure it is important in the released winding section whose tendency, even without internal mechanical support, so to speak, to remain free in space, to extend as long as possible.
  • This tendency also depends on the dimensional stability of the thread material and the turns inherent, at least temporarily, in the winding section.
  • the dimensional stability is high when the turns are wound with a curvature of the thread material that corresponds at least approximately to the smallest natural and forced curvature storage capability of the weft thread material.
  • This curvature storage capability can be explained as follows: If a section of the weft thread material is placed on a smooth surface, with the ends of the section being guided to each other as far as possible, then the weft thread section acquires a specific curvature.
  • the weft section relaxes to a residual curvature that represents its smallest natural curvature storage capability.
  • different weft thread materials differ only slightly in this regard or behave very similarly. If the weft yarn material in the roll is curved at least substantially with the smallest natural curvature storage capability, then the windings in the released winding section have no appreciable tendency to increase or decrease the winding radius so that the released winding section will be the tubular configuration formed by winding on the inner support maintains relatively long. Mutual adhesion between the uniform and contacting turns may assist this.
  • the suture delivery device is designed to perform the method of sizing the weft length for a loom that does not limit the weft length itself, e.g. for a jet loom.
  • the serving of dimensioning stop element is moved in its engagement position without own drive through the forward funded filament winding into the stop position.
  • the stop member is placed in the correct position for dimensioning the length in front of a turn just formed on the support in the engagement position, without affecting the conveying movement, and moves with the forwardly funded winding until it finally reaches the stop position in which it limits the withdrawn weft length.
  • a positive drive is provided, which adjusts the stop element exclusively in its release position substantially opposite to the take-off direction, while simultaneously thread turns can be deducted without obstruction by the stop element.
  • the stop element positioned in its engagement position is responsible for terminating the entry.
  • the stop element cooperates functionally with a thread clamp, which is responsible for the beginning of the entry and is controlled in time to the working movements of the stop element.
  • the thread clamp holds the weft thread, while the stop element is moved back in the release position, in the starting position, and releases the weft thread exactly at the beginning of the entry process.
  • the entry is terminated by the caught stop element in the stop pest before the thread clamp retains the thread in preparation for retracting the stop element.
  • the thread clamp holding the thread is adjustable so that is relaxed by its Verstellhub towards the stop element located in the stop element of the present therebetween weft thread section and relaxed when the stop element is moved for the next entry in the release position.
  • This adjustment of the thread clamp eliminates disturbances in the tubular configuration of the thread winding.
  • it may be expedient to move the thread clamp at least in the final phase of an entry from the movement space of the thread eg with a further actuator or even with the auxiliary drive. This would minimize the risk of the thread getting caught. If necessary.
  • a joint In order to have to move as little mass as possible at the taking place in the withdrawal direction of the stop element through the filament winding, a joint should be provided between the stop element and its drive. Furthermore, the stop element should be guided in the direction of movement in order to have exact positioning, at least in the stop position, which is important for the length dimensioning.
  • This guide can either be a defined hinge axis perpendicular to the take-off direction, and / or a guide track extending exactly in this direction in the support or even in a structure adjacent to this on the outside.
  • Structurally simple and functionally safe is a positive drive on a magnetic basis.
  • a stationary solenoid (solenoid) pulls or pushes the at least partially magnetically conductive stop element in the release position using the joint in the starting position.
  • other drives can be used for this purpose.
  • a perfect positioning of the stop element in the stop position is achieved by a stop in the guide either in the support or in the structure adjacent to the outside.
  • the filament winding moves the stop element in the conveying direction against the stop.
  • a controlled thread brake (end-of-insertion brake) is used in this technique usually, which dampens the voltage increase.
  • Such controlled thread brakes are expensive and require a complex control.
  • the damping takes place in that the stop element is deflected against a predetermined elastic counterforce substantially in the circumferential direction of the support, under the energy which is transferred to the stop element when the weft thread is stopped. Due to the deflection against the elastic counterforce, the weft thread is slowed down more slowly or energy is consumed which eliminates or considerably reduces the weft tension tip. As a result, a controlled thread brake for this task can be omitted.
  • This function can be achieved, for example, in that the stop element itself is elastically restoring, for example, with a resilient joint region, so that it is deflected like a spiral spring only under the energy increase of the stretch and mitigates the thread tension increase.
  • a lateral abutment for the stop element could be provided in the support or in a structure adjacent to the support, which laterally movable with the arranged stop element under the force of the weft thread against the predetermined counter force shifted to consume energy. Once the draft is over, the abutment or the stop element is back in the circumferential direction.
  • the thread clamp which is responsible for the beginning of the entry, is of considerable importance, since the release time of the weft thread must be tuned very precisely to the operation of the loom and should pass as short time between the command of the initiation of the entry and the release of the weft ,
  • the thread clamp is therefore a trigger of the entry, wherein the thread clamp in the thread path takes up as little space and just so close to the front end of the support is effective that the released thread winding part can be provided undisturbed to the entry in the desired size.
  • the adjustability of the thread clamp in the withdrawal direction is important in order to be able to relax the weft thread section present after the entry between the thread clamp holding the thread and the stop element located in the stop pest, and possibly also a disabling part of the thread clamp at least substantially to move out of the thread movement area.
  • a rotary drive for example, a stepper motor is suitable.
  • a linear drive and a magnet assembly can be used.
  • An effective clamping in the narrowest space and with precisely dosed clamping force can be achieved by a notch-like clamping area in a slim extension of the thread clamp, wherein the clamping force is generated mechanically by spring force. Because the clamping of the thread is a process of secondary importance, because then the weft thread is trapped by the stop element anyway. The spring force must ensure that the clamping force is sufficient to hold the weft under the tension generated by the entry system.
  • the thread clamp releases the weft thread at the exact desired time and as quickly as possible when the entry is to be initiated.
  • This can be functionally easily achieved by means of a switching magnet whose armature the weft thread clamped captive bolt with a predetermined distance opposite when the solenoid is energized. Thanks to the space between them, the fitting has enough time to overcome the breakaway friction and convert the magnetic force that builds up into high speed, building up high kinetic energy and accelerating it hard before it hits the bolt.
  • the shift solenoid does not need to gradually overcome the spring force starting from the zero speed, but does so abruptly with the then already achieved acceleration and kinetic energy of the valve. It comes to the sudden release of the trapped weft. In practice, release times in the range of only one millisecond can be achieved.
  • the filament winding in its released and no longer supported from the inside part for a long time tends to maintain the tubular configuration
  • External support maintains the tubular configuration and allows the weft yarn to be withdrawn radially inward from the forwardmost turn in the haul-off direction and then along the extension of the support axis so as not to create a delaying and depleting balloon and the desired high picking speed or short entry time can be achieved.
  • the guide surfaces may be formed so as to support at least the lower half of the released filament winding part. Optionally, more or even the whole filament winding part is supported. In this case, the guide surface of part surfaces or rods or the like. Existence to generate as little friction on the released filament winding part, or only there friction, where it is considered appropriate, e.g. at the top of the foremost turns in the withdrawal direction to prevent them from tipping forward.
  • At least a part of the guide surface in the withdrawal direction may be inclined upward inclined obliquely. This favors keeping the released filament winding member compact and dense as it moves forward and also when the filament is withdrawn.
  • a retaining element in the form of a lamella or a brush should be arranged above the yarn winding, the cooperates with the front end of the support to slow down the weft thread before it is brought to a complete stop at the stop element.
  • This retaining element must be adjustable so that it comes into effect only at the desired time, namely at the end of the entry, and in the remaining time does not affect the released filament winding part.
  • the support is a rod cage.
  • the fingers have individual Exzenterverstellvorraumen with a
  • the support for carrying out the method has a relatively small diameter, approximately corresponding to the smallest natural and forced curvature storage capability of the weft thread material, a simple eccentric adjustment device is sufficient because a diameter variation corresponding to a thread turn length only requires a relatively small radial adjustment path.
  • the location cam is either rotated in the carrier and displaces the finger outward or inward, or the location cam is rotated in the finger, and moves with his finger over its eccentric portion in the carrier.
  • an outer diameter between about 20 and 50 mm is appropriate, preferably between about 30 to 40 mm. This is a range of diameters within which the smallest natural and forced curl storage capability of most weft materials is.
  • the thread clamp should be aligned approximately in the direction of the stretched thread with the area at which the stop element penetrates into the support.
  • the reliability of the method can be significantly increased with a loop suppression body centrally located on the support and projecting approximately in alignment with the support axis in the withdrawal direction so that its free end protrudes at a position the support lies.
  • the fundamental advantage of the method are extremely high entry speeds or short entry times. This positive effect results from the fact that the thread when pulling on the foremost turn of the liberated winding section without balloon formation runs directly substantially radially inward and then only in the axial direction in the loom. This movement takes place with very high speed and high dynamics.
  • the loop suppression body has a rotationally symmetrical lateral surface, which tapers in the direction of the free end. This facilitates the slipping of a sling and prevents its rotation. The shape also prevents the loop from tightening under the withdrawal tension.
  • the loop-suppression body is a pin, preferably a conical pin. It also provides an ideal way to place a trigger sensor that registers each withdrawn turn.
  • the outer diameter of the pin should be at least near its free end, only a fraction of the diameter of the support.
  • the free end should protrude significantly beyond the front of the support to function in the area where the thread runs inward from the released lap section.
  • the free end in the withdrawal direction even downstream of the position of the thread clamp to reach into a range from which no looping and thus the risk of rotation of loops can occur more.
  • the lateral surface should be smooth and formed with low friction, optionally it has a low-friction support.
  • Low friction in this case means low friction for the thread material. Because the suppression body needs only by its physical arrangement and extension in about withdrawal direction to cause that emerging in the loop loops can not twist, and should exert as little delaying mechanical load on the thread.
  • a feed principle can be used with a wobble element, which is driven synchronously with the winding element, but does not rotate, but only generates a wobbling motion by its inclined axis, which transmits it to the emerging from the winding element and formed on the support first thread turn, the then pushes the thread turns lying in front of it.
  • the feed elements between the rods of the rod cage use a common drive with a skew with respect to the axis of the support or the drive shaft of the winding element axis.
  • the tension-free and loosely presented thread winding part for triggering is released by overfilling the support.
  • a supporting wiper can assist in releasing the filament winding compactly with its tubular configuration from the retracting support.
  • the support is associated with an auxiliary support at the front, which is first used to form an internally supported filament winding, but then pulled away from the support coaxially to release the filament winding part, which is intended for entry.
  • the auxiliary support can be supported by a scraper, which favors the compact holding the liberated Fadenwickelabitess.
  • the stretch or whip effect at the end of an entry in a jet loom supplied with a metering yarn feeding device with weft threads is due to the abrupt delay of the inserted weft yarn on the stopper.
  • controlled thread brakes are used, leading the interception of the weft thread on the stop element begin to brake and gradually retard the weft.
  • Controlled yarn brakes of this type require precise electronic control and are complex and expensive.
  • the stopper responsible for the whip effect is itself used to dampen the voltage rise at the entry end. That is, the damping takes place in the weft exactly where the unwanted voltage increase would be generated.
  • the stop element is deflectable substantially in the circumferential direction of the support against a predetermined elastic force over a damping stroke. Namely, the stopper is moved from a first catching position in which it starts to delay the weft thread and is acted upon by its reaction force through the damping stroke to a second catch position, wherein energy is consumed before the weft yarn comes to a complete halt.
  • the stop element is reset, which allows a total of a very clean thread control and leads to a subsequently cleanly stretched weft.
  • the damping element which is accommodated movably in a stationary guide with a predetermined direction of movement and adjustable against spring force, is adjusted by the acted upon by the reaction force of the weft yarn stop element against the spring force on the damping stroke, so that energy consumed and the yarn is gradually braked, without a significant Increase in tension.
  • the movement of the damping element need not be strictly oriented in the circumferential direction of the support, but it could quite well be an oblique direction of movement to be chosen, which approximately coincides with the direction of the resultant, resulting from the substantially circumferentially acting force in the thread from the last deduction-side winding to the stop element and the force acting substantially in the withdrawal direction force of the thread on the stop element results.
  • the automatic reset of the damping element after the removal of the thread tension tip offers the advantage of withdrawing the weft thread at least a small piece.
  • the filament winding is already formed with a plurality of turns of thread which are larger than adjacent and define points of attack for each one of a plurality of stop elements.
  • the stop elements are hook-shaped and, for example, rotationally adjustable and are brought in their co-movement with the thread winding sequentially engaged in the prepared for them enlarged turns. This is particularly useful when the filament winding is formed with a size that corresponds to a plurality of weft thread lengths to be successively entered.
  • endless weft yarn material Y for example, from a thread supply, not shown, into a displaceable by a drive M in a substantially continuous rotary winding movement R rotatable winding element W and pulled by this on an inner mechanical support S in successive or adjacent turns T is wound as a tube-like winding, which moves forward on the support S at a speed V in the arrow direction.
