The explanation of most preferred embodiment
According to the present invention, weft selector be applied to dobbies will illustrate in greater detail as follows, referring to Fig. 1 to Fig. 6.
As shown in the figure, many weft selecting rod 11(are 3 in this situation) be installed in rotation on the axle 14, axle 14 usefulness supporting plates 12 and plate washer 13 are contained in frame 10 the insides.Every weft selecting rod 11 makes it around axle 14 to counterclockwise rotating by spring 15.Weft selecting rod 11 has first deep-slotted chip breaker 11a along its bottom end surface, and axle 14 is centers of curvature of circular arc.Also be fastened on the weft selecting rod 11 in manipulation flexible axle 16 its bottom embedded groove 11a of the guide post 19 that connection weft selecting rod 11 and back will be explained with bolt 17.Handling flexible axle 16 is movably, and it is inserted through frame in the eyelet that is bored on the backbar 20 of supporting plate 12 and plate washer 13 in the bottom, in the upper end, by the eyelet that is bored on the carriage 22 that is installed in upper spider 21 bottom surfaces securely by conduit 18.
Corresponding flexible axle 16 and 26 places relative deep- slotted chip breaker 11a, 19a and the tangential direction of 19c, and at this position, they are fixed on corresponding connecting rod 11 and 19.According to this structure, as shown in Figure 2, as weft yarn Y
2Be in off-position, promptly the front end of weft selecting rod 11 is raised, and the end portion of handling flexible axle 16 almost is embedded in first deep-slotted chip breaker 11a along the total length of groove 11a.On the other hand, the ground, upper part of handling flexible axle 16 embeds in second deep-slotted chip breaker 19a, and an end of control flexible axle 26 almost embeds in the 3rd the groove 19c along the total length of groove 19c.In contrast, as shown in Figure 4, as weft yarn y
2Be in the operating position, when being the front end decline of weft selecting rod 11, the end sections ground of handling flexible axle 16 embeds in first deep-slotted chip breaker 11a, and its other end almost embeds in the second deep-slotted chip breaker 19a along the total length of groove 19a, and the end parts ground of controlling flexible axle 26 simultaneously embeds in the 3rd the deep-slotted chip breaker 19c.
Because a series of jacquard pattern (not shown) controlled motions and when position shown in Figure 1 moved to position shown in Figure 3, guide post 19 rotated to counterclockwise around axle 23, the direction of the elastic force that is produced with spring 24 is opposite when jack stick 25.Thus, corresponding weft selecting rod 11 rotates to clockwise direction around axle 14, and the direction of the elastic force that is produced with spring 15 is opposite.Therefore, as shown in Figure 5, weft yarn y
2Be positioned at weft insertion device 29 and give on the fixed track along conduction band 27 weft yarn is introduced shed open, shed open is made up of warp thread T on the slay 28 of loom, thereby motion of weft-insertion could be realized.If weft yarn y
2Motion of weft-insertion constantly repeat, jack stick 25 is maintained at position shown in Figure 3, simultaneously weft yarn y
2 Weft insertion device 29 also maintains operating position shown in Figure 4, so that can grip weft yarn.If another root weft yarn y
1Or y
3Y continues
2Later on by wefting insertion 1 and weft yarn y
2Corresponding jack stick just is returned to position shown in Figure 1, thereby corresponding therewith weft selecting rod 11 also returns to off-position shown in Figure 2.Simultaneously, corresponding to weft yarn y
1Or y
3Another jack stick 25 be in the position of Fig. 3, and its corresponding wefting insertion bar 19 and weft selecting rod 11 are thereupon weft yarn y
1Or y
3Bring the operating position into.
As mentioned above, according to jack stick 25 selected rotational motions, corresponding guide post 19 and weft selecting rod 11 correspondingly rotate around axle 23 and 14.So weft yarn y
1, y
2And y
3In a weft yarn correspondingly move to the operating position selectively.In this process, handling flexible axle 16 always leads by deep-slotted chip breaker 11a, 19a and 19c reposefully with control flexible axle 26, the result produces an external force that trends towards making the flexible axle swing along flexible axle length vertical direction, and this external force does not make a difference to weft selecting rod and the clamping weft yarn on it.This is that therefore in fact the component perpendicular to flexible axle do not exist because the end of all flexible axles tangentially embeds in the deep-slotted chip breaker.In addition, opposite with the prior art device, weft selecting rod 11 and jack stick 25 seamlessly are rigidly connected each other.Therefore, though the horizontal displacement of jack stick 25 because the vertical displacement of guide post 19 and deflection greatly, weft selecting rod 11 just by directly, transmission reposefully, simultaneously, weft yarn is arranged in exactly according to the uniform time interval and gives fixed position.This has just got rid of the interference between the adjacent weft and has stoped at shed open place formation loose weft and mixed weft.
According to present embodiment, as illustrated in Figures 5 and 6, when corresponding weft selecting rod 11 promotes, be present in the y between the edge of the thread-carrier 30 that is used to guide weft yarn and the fabric W on the loom
1, y
2And y
3Each part be positioned on the imaginary line L, this imaginary line connects the fell W of thread-carrier 30 and fabric W
1On the contrary, when weft selecting rod 11 descends, y then
1, y
2And y
3Each part be positioned under the imaginary line L.That is exactly, and this weft yarn places operating position (representing with chain-dotted line) and all the other weft yarns are in off-position, and they draw back mutually round about.When weft yarn was mobile between above two kinds of positions, even when weft yarn tangles mutually, this state had been promoted the separation between each root weft yarn.Mixed weft just can be exempted fully like this.
Fig. 7 represents the technique device that has earlier.Insert slidably in the elongated slit 4b because handle flexible axle 8, this device is difficult to assemble exactly, has faint impact resistance simultaneously.Obviously, according to the present invention, this device has been exempted above-mentioned shortcoming.
Certainly, as described above, the present invention is applicable to the loom that replaces dobby device with the jacquard weave shedding motion.
