See also Fig. 2, the synchronous shuttle guiding device of magnetic control shuttle loom of the present invention has a slay 28, this slay 28 is microscler and has two ends and a pars intermedia, and a reed 25 is fixed on the slay 28, longitudinally also is provided with a race 27 in the end face upper edge of slay 28, and respectively have a microscler separator 7 to be fixed in slay 28 end faces in race 27 both sides, and seeing also Fig. 3, Fig. 3 is the stereogram of this separator 7.Separator 7 comprises first end 72, the second end 73, central portion 74 and a plurality of shim 75, and wherein, first end 72 has the first relative end face 721 and first composition surface 722; The second end 73 has the second opposed end face 731 and second composition surface 732; Central portion 74 has relative central end face 741 and central composition surface 742; Shim 75 is connected with respectively in above-mentioned first end face 721 in spaced mode, second end face 731, with central end face 741, each shim 75 all has a sliding surface 751 simultaneously, and the sliding surface 751 of all shims 75 is all on same horizontal plane, and above-mentioned first end face 721, first composition surface 722, second end face 731, second composition surface 732 all is to tilt and is close gradually to the horizontal plane at above-mentioned sliding surface 751 places, make that the shim that is connected with on the first end 72 of separator 7 and the second end 73 is shorter, and institute's shim that is connected with is longer on the central portion 74.
Please consult Fig. 2 and Fig. 3 simultaneously, separator 7 is connected by its composition surface (i.e. first composition surface 722,742, the second composition surfaces 732, central composition surface) and slay 28, two flanks 241 that shuttle 24 is had by itself and the sliding surface 751 that is separated sheet 75 supports.Please consult Fig. 4 simultaneously, a shuttle body 23 is arranged in the race 27, is connected with the drive 29,30 of being located at slay 28 two ends by a cable wire 21, and power makes that by drive 29 inputs shuttle body 23 can reciprocating motion in race 27.
See also Fig. 5, during operation shuttle 24 be positioned over shuttle body 23 directly over, contain first magnet 232 and second magnet 242 in shuttle body 23 and the shuttle 24 respectively, therefore between first magnet 232 and second magnet 242, form a magnetic field space, make magnet 232,242 opposite magnetic pole is faced and generation suction mutually, therefore when shuttle body 23 reciprocating motions, because magnet 232,242 interattractions, shuttle 24 is moved thereupon and remain at shuttle body 23 directly over, last warp thread 35 passes reed 25 and shim 75 formation shed opens with following warp thread 34, can hold shuttle 24 and shuttle back and forth betwixt.
Because magnet 232,242 attract mutually, when shuttle body 23 moves, please contrast Fig. 3 and Fig. 5, first composition surface 722, second composition surface 732 and the central composition surface 742 of the wheel 231 butt separators 7 of shuttle body 23 and rolling, so shuttle body 23 is always vacant state.
Because shuttle body 23 reciprocating motion in race 27, therefore speed is very fast when the pars intermedia of process slay 28, when arriving slay 28 two ends, then need to slow down and stop and turning back, when shuttle body 23 slows down, shuttle 24 may break away from the attraction of shuttle body 23 and outwards fly out because of the cause of inertia force, take place for fear of this kind out-of-control phenomenon, therefore when arriving slay 28 two ends, shuttle body 23 must increase magnet 232,242 attraction, see also Fig. 6 A, Fig. 6 A is the synchronous shuttle guiding device cutaway view Amplified image at the slay pars intermedia, leave between shuttle 24 and the shuttle body 23 suitable apart from d for whole following warp thread 34 by (in fact all following warp thread are not neat forming a line, but have height to rise and fall), be approximately 3.5mm to 4mm apart from d and just can avoid when the picking shuttle 24 bottom frictions to warp thread 34 down.See also Fig. 6 B, Fig. 6 B is the cutaway view Amplified image at the synchronous shuttle guiding device at slay both ends, because at first of separator, two ends there is no warp thread and pass through, therefore the distance of shuttle 24 and shuttle body 23 can further be dwindled again, Here it is, and why once to mention the shim that is connected with on the central portion 74 of separator 7 in front longer, and institute's shim that is provided with is shorter on first end 72 and the second end 73, as shown in Figure 5, if shim 75 is long, represent magnet 232,242 distances are bigger, thus magnet suction can be a little less than, and if shim 75 is shorter, then represent magnet 232,242 distances are smaller, so magnet suction can be more intense.
At the trial, if adopt the high magnetic magnet of rubidium iron boron (the known the strongest magnet of magnetic force at present), when at the slay middle section, the distance that shuttle body 23 and shuttle are 24 is 4mm, suction is approximately 3kg, if when its distance is close to 2mm at the slay two ends, then suction can reach 8kg, to weave the loom of 75 inches cloth width of cloth, shuttle weight is 0.07 kilogram, long 360 centimeters of race, the situation that the per minute picking is several 200, shuttle 24 is at the inertia breakaway force at race 27 two ends 4kg only, and therefore the synchronous shuttle guiding device of magnetic control shuttle loom of the present invention can satisfy the demands fully.
Because utilizing, the present invention shortens between magnet apart from increasing magnetic attraction, in fact promptly be to reach by the thickness that changes separator, therefore the identical similar structures of multiple efficacies can be arranged, length as shim among Fig. 7 95 is identical, but first end 92 and the second end 93 are thinner than central portion 94, look from integral body, separator 9 is still thinner at the slay two ends, and magnetic attraction is stronger.
See also Fig. 8, Fig. 8 is a structure of representing the another kind of different types of shuttle body according to Fig. 5, and shuttle body 26 directly is resisted against on the separator 7 because of the suction of magnet 232,242, with aforementioned by wheel against mode different.
