Preferred version of the present invention
Now, with hereinafter with reference to the structure of description of drawings according to electronic double lift jacquard shedding device of the present invention.
In fabric weaving machine, separately to form shed open, this device comprises a lifting-hook executor 101 and an electromagnet to electronic double lift jacquard shedding device of the present invention with many warp thread.
This lifting-hook executor 101 has one and is assembled together with the hook 103 of control with the relative position of lifting-hook 120 with lifting-hook 120, and lifting-hook executor 101 utilizes steady pin 102 and a frame assembled together, thereby with an angle rotary of being scheduled to.Based on steady pin 102, lifting-hook executor 101 forms permanent magnet 104,105 on its both sides.This permanent magnet is to form like this, that is: the appropriate section of this lifting-hook executor body is magnetized or permanent magnetic iron block can be inserted lifting-hook executor body.When determining the magnetic force direction of this permanent magnet, if a side magnet forms one ' N ' utmost point in its surface, then opposite side magnet also forms ' N ' utmost point in its surface.That is, these permanent magnets form mutually the same magnetic pole in its surface.This is because if electromagnet is magnetized, and an end of electromagnetic core forms ' N ' utmost point, and the other end forms ' S ' utmost point, thereby makes the lifting-hook executor produce pulling force and produce repulsion at its other end at the one end.
Electromagnet forms by twine a coil 110 on one " Contraband " shape electromagnetic core 109.It is relative and be assembled together by pin 108 and framework 130 that the two ends of electromagnetic core all are designed to permanent magnet with lifting-hook executor 101.With electromagnetic core be the two ends that holistic holding components 107 and 111 is formed at electromagnetic core, comprise a pin hole on it, so it is fixed by the pin on the framework 130 108 and 112.It is feasible that electromagnetic core directly contacts this layout with permanent magnet, still holding components 107 and 111 is made than electromagnetic core and is protruded some so that the permanent magnet that is formed on the lifting-hook executor is desirable with this layout that electromagnetic core does not directly contact.If the two ends of electromagnetic core directly contact with permanent magnet on being formed at the lifting-hook executor, then since between magnet very strong pulling force be difficult to electromagnetic core and permanent magnet are separated.Furthermore, if electromagnetic core directly appends on this magnetic pole, then this magnetic pole will apply very strong pulling force.Yet if the gap occurs between this magnetic pole and the Magnetized Material, this magnet only shows very weak magnetic force.Therefore, permanent magnet is inserted into end than darker position, lifting-hook executor surface or holding components 107 and 111 and forms that more to protrude than the end of electromagnetic core be desirable, and electromagnetic core does not directly contact with permanent magnet like this.
If the signal of telecommunication is applied on the magnet spool 110, then electromagnet is magnetized, thus the permanent magnet of repulsion lifting-hook executor one side and attract the permanent magnet of its opposite side.Therefore, this lifting-hook executor 101, is formed at hook 103 and lifting-hook 120 coupled/separated on the lifting-hook executor 101, thereby has controlled the relative motion of lifting-hook 120 with respect to lifting-hook executor 101 when 101 revolutions of lifting-hook executor to side direction revolution.
One spring 106 is installed between the end and framework of lifting-hook executor 101, thus make lifting-hook executor 101 under the effect of elastic force with predetermined direction revolution and be in its initial position (shown in broken circle among Fig. 1 ' A ').In the case, if the signal of telecommunication is applied on the magnet spool 110, then electromagnet is magnetized.The direction of magnetization of electromagnet determines, causes electromagnet to attract to be arranged in the permanent magnet on the side that spring 106 is installed and repels permanent magnet on the side relative with the side that spring is installed.Therefore, lifting-hook executor 101 is removed the power of spring 1 06 and is turned round (shown in broken circle among Fig. 1 ' B ') round about to a normal position, therefore the hook of lifting-hook executor matches with the groove 121 or 122 of lifting-hook 120, thus the relative motion of control lifting-hook 120.Then, if the signal of telecommunication disappears, electromagnet loses magnetism, and lifting-hook executor 101 is got back to its initial position (position ' A ') under the thrust of spring 106.
Therefore, if send the signal of telecommunication here, then the motion up and down of lifting-hook 120 is controlled, thereby formed shed open by griffing 140 driving from the jacquard control module.
Lifting-hook 120-2 is griffed 140 to be promoted, and if the signal of telecommunication be applied on the electromagnet, under the magneticaction of electromagnet, the lifting-hook executor becomes state ' B '.Like this, the hook 103 of lifting-hook executor matches with the groove 122 of lifting-hook, even and griffe to descend, lifting-hook 120-2 does not also descend and remains on above-mentioned state.If there is not the signal of telecommunication to be applied on the electromagnet, because the magnetic force of electromagnet, executor becomes state ' A '.The hook 103 of lifting-hook executor no longer matches with the groove 121 of lifting-hook like this, and if griffe to descend, lifting-hook 120-1 also descends.At this moment, griffe to be adjusted to direction respect to one another up and down for two and move, thereby make shedding operated by jacquard machine in the double action mode with carry out at a high speed.If loom moves at faster speed, then griffe to move apace, and make the repeating motion of lifting-hook very fast.In the case, the power that is applied on the lifting-hook is produced by the synergy of electromagnet magnetic force, permanent magnet magnetic force and spring force, this just makes the lifting-hook executor move with very fast speed and more reliable mode, and this makes that wrong generation is reduced significantly.
Can obviously find out from above-mentioned, electronic double lift jacquard shedding device can be controlled the motion of lifting-hook executor by the synergy of electromagnet magnetic force, permanent magnet magnetic force and spring force, whereby the lifting-hook executor can be at full speed and more reliable mode move, this makes reliability of operation obtain significant improvement.
