Definitions

  • the invention relates to a method for holding a weft thread in the mixing tube of the main nozzle of a jet loom, in particular air jet loom, prior to the entry of the weft thread in a shed formed by warp threads.
  • the weft thread to be introduced into the shed is fed by a so-called yarn store, also called a pre-pulser or a pre-pulser, to a pneumatically-acting main nozzle of a predetermined length representing a weft insertion means.
  • the main nozzle has an injector and a mixing tube, which receives a weft thread and holds there until entry of the weft thread in the shed.
  • the remaining part of the weft thread is located between the main nozzle and the thread storage / Vorsputer and on the thread storage / Vorspuler itself and is there held up to the entry of the weft.
  • the weft thread located in the mixing tube of the main nozzle is held stretched before its entry by means of an air flow, which acts in the direction of the longitudinal central axis of the mixing tube.
  • an air flow acts in the direction of the longitudinal central axis of the mixing tube.
  • the actual weft insertion is very short and occurs depending on the yarn quality at a pressure of between 1.0 to 6 bar, the pressure of the holding air usually between 0.1 and 1.5 bar.
  • the pressure of the holding air in the main nozzle must be further increased in comparison to normal yarns in order to maintain the same constant as possible To achieve thread tension.
  • higher pressure in the main nozzle / injector usually results in higher air consumption.
  • a device for feeding weft threads for a loom with at least one nozzle which has an inflow opening for a pressure medium, which is formed so that the pressure medium undergoes a rotation about the longitudinal axis of the nozzle, whereby a in the device located weft yarn rotation or an additional rotation is granted.
  • the thus having a swirl pressure medium keeps the weft thread between the individual shots a longer time, with too high a rotation should be avoided, since otherwise would result in a tissue with reduced quality.
  • the air flow having a swirl in the mixing tube of the main nozzle is exerted on the weft thread essentially during the entire time while it waits for its entry into the shed.
  • the clamping device required for this purpose is arranged in the region of the outlet end of the mixing tube in which the weft thread passes into the shed.
  • the clamping device may for example consist of a slide which is displaceable transversely to the longitudinal direction of the mixing tube as a lifting member and clamps the weft thread located in the mixing tube between the passage opening of the slide and the inner wall of the mixing tube.
  • Another embodiment provides a transversely displaceable punch which presses the weft thread against the inner wall of the mixing tube.
  • a further embodiment of the known mixing device is provided, according to which a portion of the mixing tube is formed as an elastic intermediate piece.
  • the intermediate piece is to be compressed by two diametrically opposed lifting members, when they are moved against each other. The weft is then pinched by the compressed elastic spacer.
  • the weft thread is displaced laterally during clamping, so it is no longer in the central longitudinal axis of the mixing tube. Also in the third embodiment, this phenomenon is to be feared because only two lifting members are provided for compressing the elastic intermediate piece, the compression is therefore not strictly centrally symmetrical. A position of the weft thread outside the longitudinal center of the mixing tube prepares difficulties in the subsequent entry of the weft thread in the shed.
  • WO 02/095106 A1 deals with an air-jet weaving machine in which several main nozzles are combined with the associated mixing tubes to form a compact parallel arrangement.
  • This known air-jet loom is thus set up for generating weave patterns and processing multiple colors.
  • the weft threads located in the main nozzle and the mixing tube are held here by clamping action until the weft thread in question is released for entry.
  • the clamping devices are arranged between a Hilfsblasdüse and a Hauptblasdüse, so are always at the entrance of the main nozzles and thus outside of the mixing tube.
  • the clamping device is also equipped with mechanical clamping members in the air jet loom according to WO 02/095106 A1.
  • mechanical clamping members designed as a piston or plunger longitudinally displaceable clamping members are moved pneumatically. Under the influence of overpressure they clamp the associated weft thread against an inner wall of the clamping device, while the resetting of the clamping members and thus the release of the weft threads takes place in that the clamping members are connected to a vacuum source.
  • the invention has for its object to provide a method for holding a weft yarn in the mixing tube of the main nozzle of a jet loom, in particular air jet loom, and a jet loom for performing the method with which largely independent of the nature and quality of Schussgame the amount of holding air required can be significantly reduced or even completely waived holding air, which further a compact arrangement of main nozzles and mixing tubes is possible, the waste in fabric production are reduced and a negative impact is prevented by holding on the weft yarns, and the overall quality of the fabric produced is increased.
  • the inventive solution according to claim 1 thus consists in a method for holding a weft thread in the mixing tube of the main nozzle of a jet loom, in particular air jet loom, before the entry of the weft thread in a shed formed by warp shed, wherein a flexibly formed portion of the mixing tube by applying from outside by means of a Pressure medium is compressed and holds the weft thread clamped.
  • a purely hydraulic or pneumatic actuation takes place in that a pressure medium compresses the flexibly formed partial region of the mixing tube.
  • the weft thread is held clamped; this type of clamping causes the yarn of the weft yarn is not adversely modified. It has been shown that a clamp in this regard is not critical, while holding air the game relatively quickly and adversely modified.
  • the compression of the elastic portion of the Mixing tube by direct admission by means of a pressure medium allows a very low-inertia operation, which can accommodate the associated facilities to save space.
  • mechanical shocks that could lead to vibrations of the mixing tubes during operation, largely avoided in this type of operation.
  • the clamping takes place essentially in the region of the outlet end of the mixing tube.
  • this type of clamping a largely central arrangement of the weft thread in the mixing tube is ensured even without the application of retaining air. This favorable conditions for a correct entry of the weft thread in the shed are given when the weft thread is released to the entry.
  • the flexibly formed partial region of the mixing tube is deformed so far in the direction of its longitudinal central axis by means of the pressure medium that the weft thread is clamped in the region of the central longitudinal axis.
  • two diametrically opposed lifting members are provided, which can not uniformly compress the flexible and elastic portion, but only irregularly deforming, takes place in this type of process, an exactly centralsymmetrisches, uniform compression ,
  • the weft thread is clamped and held exactly in the central axis of the mixing tube.
  • the clamping device thus effectively forms a central closure, which aligns the weft centrally symmetrical and thus creates the optimal conditions for entry into the shed.
  • the already very low-inertia actuation according to the method of the invention is thereby further improved that, according to a further embodiment for accelerated cancellation of the clamping and release of the weft yarn of the flexible portion of the mixing tube is controlled from the outside under negative pressure.
  • the flexible portion of the mixing tube is controlled by means of compressed air at an overpressure of less than 2.0 bar for clamping and released by means of compressed air at a negative pressure of less than - 50.0 mbar.
  • the weft thread can then be inserted in the correct position in the shed. But to exclude any unwanted displacement of the weft before his entry into the shed and also to achieve its required extension, in a short transition period between the release of the clamp and the entry in the shed the weft thread can be kept temporarily by longitudinally flowing holding air.
  • a certain weft thread is held with retaining air only when it is inserted into the shed with the clamping open, when it is to be entered as the next weft thread due to the pattern.
  • the weft yarn is held only between arrival arrival of a previously entered weft thread and triggering of the pressure pulse before the entry of the next weft with holding air.
  • This embodiment of the method according to the invention is of course of the utmost importance in multicolor weft insertion. For this purpose, namely a certain weft yarn to get a longer waiting time, if required by the pattern. During the entire waiting period, the weft thread is thus held solely by clamping. In this time, holding air is not required, and thus eliminates the adverse effects of holding air on the weft thread by modifying it. Only when a weft thread is previously registered immediately, and the entry of the respective held weft thread is imminent, this weft yarn is held for a short time with holding air to bring him in the optimal state for its entry and a position within the position of the mixing tube.
  • the weft thread is held with a defined clamping force, so that it does not slip out of the main nozzle and still retains the optimum position for later entry as possible.
  • the method according to the invention it is possible to interweave yarns which hitherto could not or could not be readily woven with jet looms, in particular air jet looms, even for a high-quality fabric.
  • These include, for example, caterpillar twine and twisted elastic yarn, which can now be processed relatively easily with the method according to the invention, especially in air jet looms.
  • the method can be used particularly advantageously if weft threads of different colors are introduced in order to be able to weave specific patterns.
  • a significant advantage of the method according to the invention is that according to the pattern repeat in the case of several, usually for the main nozzle associated with each color, the clamping of the weft thread is pattern-dependent. In this case, the weft thread is kept clamped during its entire "waiting time" on the entry until just before his entry.
  • the short-term holding by means of holding air represents only an additional optimization, because in a centrally symmetric clamping anyway good conditions for a correct entry of the weft thread are given.
  • the weft thread receives the necessary thread tension and an optimal position in the mixing tube. Because of the only short exposure time of the holding air in the case of the method according to the invention, wherein retaining air is only required if the entry of the weft thread imminent, avoids the adverse modification of the weft thread by the holding air.
  • a jet loom in particular for carrying out the method according to one of claims 1 to 7, with at least one main nozzle, comprising an injector with a compressed air connection and a mixing tube adjoining the injector, with a clamping device arranged in the mixing tube, which is formed by a flexibly formed portion of the mixing tube and for clamping a weft thread located in the mixing tube to the inner wall of the mixing tube, and with a device for acting on the flexibly formed portions of the mixing tube by the pressure medium in the manner that the subregions when pressurized by the pressure medium under a certain pressure P, the weft thread clamping be compressed and return to its original position when pressure relief.
  • the clamping device is a central closure in the form of a pneumatic or hydraulic muscle.
  • the pneumatic or hydraulic muscle clamps the weft thread substantially in the region of the central longitudinal axis of the mixing tube.
  • the hydraulic or pneumatic muscle is due to the fact that a portion of the mixing tube is made of a flexible and highly elastic material.
  • the pressure medium especially compressed air, acts uniformly from the outside and centrally symmetric on the muscle, so that with maximum security a clamping in the region of the central longitudinal axis of the mixing tube comes about.
  • the pneumatic or hydraulic muscle is arranged between a first and a second mixing pipe section and connects the two mixing pipe sections sealingly, wherein the pressure medium acts on the muscle in a surrounding chamber.
  • An optimal positionally correct holding of the weft thread is achieved in that, according to a development, the clamping device is arranged on the nozzle opening of the mixing tube.
  • the control of the pneumatic or hydraulic muscle can be carried out in such a way that the pressure pulse triggered in the injector of the main nozzle for insertion of the weft thread releases the clamping effect of the clamping device.
  • This training is advantageous because the clamping must be canceled anyway before the entry of the weft thread in the shed.
  • the chamber can be connected to a vacuum source.
  • the release of the clamping action is thus not simply by the fact that the action of an overpressure from the outside is terminated on the muscle, but at the same time compressed air is blown through the interior of the muscle, and also the chamber surrounding the muscle can be exposed to the action of negative pressure.
  • the necessary connections can be made via solenoid valves, and as a vacuum source can serve a vacuum pump.
  • an advantageous development further consists in that the inventive jet loom is provided with a control device which causes a coordinated interaction in the supply of compressed air from a compressed air source to the injector and provided with a pressure sensor clamping device, wherein the compressed air serves as a pressure medium for the clamping device ,
  • the clamping device can be held in its open position immediately before the entry of the weft thread and holding air can be introduced into the mixing tube only when the clamping device is open via the injector.
  • the weft thread is held in the longest span of its "waiting time" by clamping by means of the pneumatic or hydraulic muscle. Only shortly before its entry is held by means of retaining air, whereby the position and the condition of the weft thread are optimally prepared for the entry in the shed. Compared to the prior art, this significantly reduces the risk that the game will be adversely modified by the holding.
  • the weft thread is separated in the direction of insertion by means of a cutting device. This happens at a time in the pressure pulse triggered by the injector of the main nozzle has dropped again so far that the pressure in the chamber surrounding the muscle outweighs and re-clamps the weft thread at the nip.
  • the control of the opening and closing of the clamping device takes place in dependence on the property of the muscle forming elastic piece of hose.
  • Such a pressure-balanced system in terms of the maximum pressure of the output from the injector of the main nozzle pressure and the pressure of the pressure medium, which compresses the muscle for holding the weft yarn is for particularly fast changing cycles, that in this case weaving cycles, for air jet looms particularly high speed suitable.
  • the inventive jet loom can still be modified with such a design of the control device in an advantageous manner that the clamping device is close enough to close the end of the entry of the weft yarn that the weft yarn is braked during this phase of his entry, so that he braked by the Clamp slips through.
  • This can be achieved by targeted control of the pressure difference / the pressure differences between the pressure pulse or the shape of the pressure pulse and the pressure or the pressure curve in the chamber surrounding the clamping device.
  • the clamping device then acts as a brake during a time range shortly before the end of the weft insertion.
  • this braking device can achieve a gentle removal of kinetic energy from the weft thread which has been accelerated to a high speed during the application. In this way, the directed at the end of the weft yarn usually to stop stop the Vorspulers movement of the weft yarn (spring back) is largely avoided.
  • serving as a thread brake clamping device can be counteracted this jumping back (loosening) of the weft thread to stop element, without - as it is common in the art - a higher Stafettendüsendruck, the use of a stretching nozzle and / or increased waste lengths are the result.
  • the clamping action during the gradual deceleration is controlled by the pressure difference so that the weft thread slips smoothly through the clamping device, without being himself modified. It has been found that the adjustments between the pressure or pressure curve in the chamber and the pressure pulse or the shape of the pressure pulse are so fine can be realized that the braking action is optimally adjustable depending on the type and quality of the weft. This effect is achieved without a deterioration of the tissue quality. Rather, the opposite is the case, because the quality of the fabric was significantly improved compared to an unrestrained entry of the weft.
  • a pre-pulse is triggered by the injector, which is detected by the pressure sensor and serves as a trigger of opening the clamp.
  • the amplitude of the pre-pulse is chosen so that it is greater by a defined amount than the pressure in the chamber surrounding the muscle, the duration of the pre-pulse at least equal to the duration of the entry of the protective thread.
