Definitions

  • the present invention concerns a method and a device for supplying weft thread in a weaving machine, as well as a brake and/or damper mechanism for weft thread applied thereby.
  • weft thread is taken from a weft accumulator, and this weft thread is brought in the shed via insertion devices, after which the inserted length of weft thread is beaten against the cloth line in the known manner by means of the reed.
  • weft thread is inserted by means of nozzles, in particular one or several main nozzles and relay nozzles
  • the weft thread is exposed to relatively large tensions, which may lead to thread breaks. These tensions occur especially at the end of the insertion cycle.
  • the supply of weft thread is interrupted at the end of the insertion cycle by blocking the weft thread on the insertion side of the shed. Due to this sudden blocking, and also because the weft thread has a certain inertia, relatively large tensions arise.
  • the present invention aims a method and device for supplying weft thread which are improved in relation to the known embodiments.
  • the invention in the first place concerns a method for supplying weft thread in a weaving machine, in particular a pneumatic loom, whereby weft thread is taken from a weft accumulator and this weft thread is brought in the shed via insertion devices, and whereby this weft thread is carried between the above-mentioned weft accumulator and above-mentioned insertion devices along a brake and damper mechanism with which, during the insertion cycle, it is possible to exert a brake action as well as a damping action on the weft thread, characterised in that the weft thread is carried, in the above-mentioned brake and damper mechanism, along at least one movable thread guide on the one hand, which can bring about a damping effect with regard to the tension in the weft thread, and also along at least two other thread guides on the other hand, of which at least one can be moved and which always allow for a bending, irrespective of the position of the first-mentioned thread guide.
  • This method offers the advantage that when the thread guides which have to bring about the brake effect are excited, a bending is always guaranteed, even when, due to a failure of the thread guide which has to bring about the damping effect, the latter thread guide can no longer provide for a bending as such. Hence, this also implies that the brake effect remains guaranteed, even when the damping action should fail.
  • Another advantage consists in that the brake effect, if required, can be disconnected from the damping effect.
  • the thread guides which make sure that a bending of the weft thread is always possible, or at least the movable thread guide or thread guides that are part of them, are driven and moved by means of a position control, for example by means of a step motor.
  • a position control for example by means of a step motor.
  • the movable thread guide which is intended to bring about a damping effect is forced with a certain force out of the path of the weft thread, at least during certain parts of the insertion cycle. In this manner, it is possible to set a specific stress level above which damping occurs.
  • the movable thread guide which aims to bring about a damping effect is preferably forced into a stop position by means of said force, with such a force that this thread guide, at least while said force is being exerted, is only released from the stop position during stress peaks in the weft thread.
  • a stop position offers the advantage that the thread guide bringing about the damping effect remains in one and the same position during the normal brake action, so that the bending of the weft thread can only be controlled by means of the movement of the other thread guides, which allows for an accurate adjustment.
  • the thread guide which aims to bring about a damping effect is excited with gas pressure, at least during the periods when a damping action is required, in particular air pressure, either overpressure or underpressure.
  • gas pressure in particular air pressure
  • Such a control by means of gas pressure, in particular air pressure offers the advantage that one has a relatively large adjustment range.
  • the movement of said thread guide is carried out by means of a transmission mechanism upon which can be exerted a force by means of gas pressure on one side, resulting in a lateral force on the thread guide on the other side, whereby the above-mentioned transmission has such a transmission ratio that there is a force reduction.
  • a transmission mechanism upon which can be exerted a force by means of gas pressure on one side, resulting in a lateral force on the thread guide on the other side, whereby the above-mentioned transmission has such a transmission ratio that there is a force reduction.
  • a transmission mechanism with a transmission ratio so that the force is at least reduced by half, in other words, a specific force is obtained by means of a gas pressure, resulting in a force at the thread guide which is half or less than half of the first-mentioned force.
  • the invention also concerns a device for supplying weft thread in a weaving machine which makes it possible to realise the above-mentioned method.
  • the construction of such a device will become clear from the following description.
  • This document also describes a device for supplying weft thread in a weaving machine, in particular in a pneumatic loom, whereby this device comprises a damper mechanism for stress peaks in the weft thread, with a thread guide which, under the influence of the thread tension, can be moved against a specific force, characterised in that this damper mechanism for exciting and moving the thread guide bringing about the damping action comprises devices, such as a little pressure cylinder or such, which can be excited by means of a gas pressure, in particular air pressure, either overpressure or underpressure, whereby these devices are connected to the above-mentioned thread guide via a transmission, whereby this transmission provides for a force reduction.
  • the invention concerns a device 1 for supplying weft thread 2 in a weaving machine 3.
  • This device 1 comprises devices 4 for supplying weft thread 2 from a weft accumulator 5, as well as insertion devices 6 to systematically bring the supplied weft thread 2 in the shed 7.
  • the weft accumulator 5 consists of one or several bobbins 8, while the devices 4 are formed of an accumulator 9 which, as is known, consists of a prewinder drum 10 upon which weft thread 2 can be wound by means of a winding arm 11, and along which is provided a pin 12 which can be activated which, by means of a control, allows weft thread 2 to be either or not taken from the prewinder drum 10.
  • the actual insertion devices 6 consist of one or several nozzles, in this case a main nozzle 13 and several relay nozzles 14 provided in the shed 7.
  • the reed 15 and the formed cloth line 16 are indicated in figure 2 , as well as the warp threads 17, a thread collection element 18 arranged at the end of the shed 7 and a weft cutter 19 arranged at the inlet of the shed 7.
  • the present invention is special in that the device 1 comprises a brake and damper mechanism 20 for the weft thread which is provided between the above-mentioned devices 4 and the insertion devices 6, whereby this brake and damper mechanism 20 at least consists of at least one movable thread guide 21 which can bring about a damping effect with regard to the tension in the weft thread 2, as well as of at least two other, in this case even four other thread guides 22-23-24-25, at least one of which, but in this case two, namely 23 and 24, are movable, which always allow for a bending, irrespective of the position of the first-mentioned thread guide 21.
  • the thread guides 22 and 25 are preferably arranged fixed, and the thread guide 21 is situated in line with the thread guides 22 and 25 when in rest.
  • the movable thread guides 23 and 24 are situated in such a position when in rest that they do not provoke a bending of the weft thread 2, at least when the thread guide 21 is in rest as well.
  • the thread guides 21, 22 and 25 preferably consist, as represented, of thread eyes, while the thread guides 23 and 24 are formed of elements which are arranged alongside the weft thread 2.
  • the thread guides 21, 23 and 24 are movable in directions which stand crosswise to the general feed-through direction of the weft thread 2.
  • the thread guides 23 and 24 are fixed to one another and can be moved together by means of drive devices 26 which preferably allow for a position control, in other words which make it possible to bring the thread guides 23 and 24 in one or several specific positions, possibly as a function of different parameters and either or not as a function of the course of the insertion cycle.
  • these drive devices 26 consist of a controllable step motor.
  • the yarn break mechanism 20 is provided with devices 27 with which a certain force F can be exerted on the thread guide 21, according to the direction of movement in which the thread guide 21 can be moved.
  • These devices 27 preferably consist of a drive element which can be switched on and off which, when switched on, forces the thread guide 21 into a stop position with said force F, determined by a stop 28, such that, in this stop position, the thread guide 21 is situated in the prolongation or almost the prolongation of the path which is normally followed by the weft thread 2, in other words in the position as represented in figure 3 .
  • the devices 27 make it possible to set the value of the force F such that the thread guide 21 can only be released from the stop position during stress peaks in the weft thread 2.
  • the devices 27 are preferably made such that, when these devices 27 are not excited, the thread guide 21 concerned freely follows the position of the weft thread 2.
  • the weft thread 2 When a length of weft thread 2 must be inserted in the shed 7, the weft thread 2, as is generally known, is released at the accumulator 9 by withdrawing the pin 12, and the weft thread 2 is blown in the shed 7 by activating the nozzles concerned, in particular the main nozzle 13 and the relay nozzles 14. As a result, the weft thread 2 will move through the shed 7, until its front end has reached the far end of the shed 7. At that moment, the yarn supply as of the accumulator 9 is interrupted by exciting the pin 12.
  • a yarn brake as well as a tension damping are provided during the weft cycle by means of the yarn brake mechanism 20.
  • the thread guides 21 and 23-24 are in the position as represented in figure 3 , whereby it is clear that there is no braking or damping whatsoever, as all these guides are in line with the fixed guides 22 and 25.
  • the devices 27 are preferably permanently excited, and the guide 21 is thus permanently pushed into the stop position.
  • the thread guides 23 and 24 are moved by means of the drive devices 26, as a result of which, as represented in figure 4 , several bendings are realised, so that a brake effect is created due to the ensuing friction between the weft thread 2 and the respective thread guides.
  • the drive devices 26 allow for a position control, the position of the thread guides 23-24 can be set as a function of different parameters, such as the required brake effect, the nature of the weft thread and the like. Also a control as a function of the course of the insertion cycle is possible, either or not on the basis of feedback values.
  • the brake effect reduces the speed of the weft thread 2 and thus also its remaining inertia, so that when the weft thread 2 is stopped, the yarn tension therein is lower than in the case when no braking action would have preceded.
  • the invention is special in that, by doing as described above, it is always possible to obtain a brake effect by means of a bending, even when, due to failures, the damping effect provided by the thread guide 21, would get lost.
  • This is schematically illustrated in figure 6 .
  • This figure shows that when a force F is no longer exerted on the thread guide 21, and the latter thus ends up in line with the thread guides 23 and 24, it is still possible to bring about a good bending and brake effect.
  • the invention also offers the advantage that the damping effect can be switched off, while at the same time a brake effect can still be realised.
  • FIGS 7 to 9 represent a practical embodiment of the brake and damper mechanism 20.
  • the thread guides 22 and 25 hereby consist of thread eyes provided in supports 29 and 30.
  • the thread guides 23 and 24 are formed of a brace 31 mounted on a shaft 32 which can be revolved by means of a step motor 33.
  • the thread guide 21 consists of a thread eye which is provided at the end of an element which can rotate around a shaft 34, in particular a lever 35, which can work in conjunction with the stop 28.
  • the mechanism 20 is provided with devices 27 which make it possible to excite the thread guide 21 by means of gas pressure, in particular air pressure, in order to obtain the above-mentioned damping effect.
  • the devices 27 comprise a little pressure cylinder 36 to which compressed air can be supplied via a controlled valve 37.
  • the pressure cylinder 36 has a piston 38 which is coupled to the lever 35 so that, by supplying compressed air, the lever 35 is moved and forced against the stop 28.
  • the lever 35 forms a transmission mechanism which preferably provides for a force reduction, since, as indicated in figure 9 , the lever arm A is shorter than the lever arm B. A is preferably smaller than or equal to the half of B, so that the force is at least reduced by half.
  • brace 31 When in rest, the brace 31 is in a position as represented in figures 8 and 10 .
  • Another advantage is the very low inertia of the transmission and its drive, since no mechanical springs or electromagnetic elements need to be used. As a result, the system concerned can easily react with a high frequency on a stepwise thread tension increase, it will have a low time constant and can easily make deflections when necessary.
  • the lever 35 can be made in a simple manner as a movable finger which can push laterally against the weft thread 2, whereby this finger is situated outside the path of the weft thread 2 when in rest, whereas it swings while being excited and is pushed with a certain force against the weft thread 2.
  • use can be made of devices to push the above-mentioned finger with a certain force against the weft thread 2 on the one hand, and of recall devices to bring the finger in a position of rest when it is not activated on the other hand.
  • the magnitude of the force F can possibly be adjusted, for example as a function of different parameters.
  • Such an adjustment may take place on the basis of parameters that are known beforehand, for example the type of weft thread 2, or on the basis of parameters which vary during the weaving, either or not as a function of measurement data.
