However, the problem arises that the electromagnetic device on the guiding element needs to be fast, and the spring supply/heling method has a great disadvantage, that is, the generation of heat and the supply of the power supply cable on the woven fabric are "high cost. In addition, the disadvantage is that a control device needs to be installed and used to handle the synchronization problem when the textile speed is increased, or a complicated sensing mechanism is required. Although the European patent case Ep-A-0 69〇!6〇 also proposes a permanent magnet 乍 as a force generating device. However, it is suggested that a permanent magnet be placed near the end of the rapier return end at which the weft yarn is introduced to the starting end. A simple single-point weft yarn transfer method and a European patent application ΕΡ-Α-0 990 723 propose a solution to this problem. A rapier having a permanent magnet passes between a pair of permanent magnets, so that the rapier is at the position. Was opened. However, according to the European patent application ΕΡ-Α-0 990 723, measures to install permanent magnets along the rails must be discarded. A rapier device has been disclosed in the international patent application WO-A-99/60193, which has overcome the problem of high cost electromagnets on the weaving knives, which are provided on each rapier for opening and closing the rapier head 6 200825227 Electric actuator. It is proposed in the international patent application WO-A-99/60193 that the electric actuator comprises an electromagnet, a piezoelectric element or a linear motor. Although the provision of an electromagnet or a linear motor does not require the application of wires along the guiding elements to the woven fabric, the second rapier requires a relatively high power supply. To the use of a piezoelectric element as a source of force for the actuator, the problem of providing the necessary reaction force of the actuator is generated. In addition, the two rapiers must be powered, so they still need to carry the environment. The problem is basically not solved. SUMMARY OF THE INVENTION The object of the present invention is to improve the weft introducing device of the rapier loom described above. For rapiers and their guiding elements that require a large number of power cables to be laid, the power supply should be required. "U', this task is based on the material of the rapier loom described in item 1 of the patent application scope, and the cable wire for each electromagnetic switching element can be completely eliminated. In addition, the complex electronic control that must be used in '-0 690 160 1 can save the permanent magnets of the job and the closing _ on the slide rails, thus avoiding the bad setting of installing the permanent magnets under or above the rapier. The iron (four)/set is more simplified and more reliable. The side rods are arranged under the _ by, and ^ by the permanent magnets in the phase rods of the permanent magnetic weft yarns, and the permanent magnets in the rods and the slides. The rapier is delivered by the weft rapier, and the hunting is achieved by the parallel movement of the Dawei rapier and the weft rapier. To the second "II:: the introduction of the device is advantageous in the second paragraph of the patent application scope 2 (4), the slide rails of the axis of the shaft and the 7 200825227 five particularly advantageous according to the third application of the patent application park Said, the weft rapier and the % rapier are transported in parallel, and the yarn of the shaft is clamped, and the yarn clamp of the weft rapier has been closed. In order to assist the child to open and close or only In order to increase the force of opening and closing ^: the root shot, please fill in the 4 items of the cofferdam, and set the permanent magnets with the opposite polarity of the two magnetic poles on the sending rapier and the rapier, which can be along the sliding rail. A permanent magnet having the opposite polarity of the two magnetic poles is disposed at each of the weft receiving position and the weft releasing position.
