The specific embodiment
In conjunction with Fig. 1 to Fig. 6 the form of implementation of Sewing machines open system of the present invention is described.
As depicted in figs. 1 and 2, this opening device 1 is used in by the outer shuttle of being fixed on the shuttle axle 4 that synchronously rotates with the elevating movement of pin 9 and rotatably is embedded in sewing machine for covering chain stitch that the interior shuttle 10 in the outer shuttle 9 constituted with in the horizontal shuttle.The engaging protrusion 10a that the periphery of shuttle 10 is provided with highlightedly in said is flush-mounted between a pair of latch for printed circuit 12,13 that is arranged on below the needle plate 11 movably.
Opening device 1 inside shuttle 10 lateral bending songs.When owing to eccentric cam 5 along with the rotation of shuttle axle 4 is rotated, when the restriction that shuttle guid arm 2 is guided connecting rod 3 because of shuttle in being subjected in making is swung, will be as shown in Figure 5 with the opening device end 1a that interior shuttle contact site 10b is inconsistent, depict elliptic motion trace.That is, the opposite spin of shuttle 10 outside shuttle direction of rotation A in making, thus when engaging protrusion 10a broke away from latch for printed circuit 12, opening device end 1a depicted elliptic motion trace to the clockwise direction identical with outer shuttle 9 direction of rotation A.
Suppose that outer end position with interior shuttle contact site 10b is initial point, is that Y-axis, vertical with it line are X-axis through the line of interior shuttle contact site 10b, at this moment, above-mentioned elliptical trajectory is on Y direction, promptly elongate along the direction of interior shuttle contact site 10b.By this elliptical trajectory as can be known, before interior shuttle contact site 10b soon contacted, the speed of opening device end 1a was reduced to low speed.Therefore, can not produce the two strike note of opening device end 1a and interior shuttle contact site 10b basically.In addition, as shown in Figure 3, velocity component when contacting with interior shuttle contact site 10b as opening device end 1a, the component of Y direction is greater than the component of directions X, so when upper thread can be fully guaranteed by the time between engaging protrusion 10a and the latch for printed circuit 12, the oscillating quantity of interior shuttle 10 can be suppressed less, therefore, can make the tension stability of bottom line, form good seam mark.And at opening device end 1a with after interior shuttle contact site 10b contacts, though the translational speed of X-direction is quickened, but in leaving before the shuttle contact site 10b, to slow down again and be low speed, therefore, interior shuttle 10 will rotate lentamente, can avoid the powerful rotation of Yin Neisuo 10 and the engaging protrusion 10a that causes and the bump of latch for printed circuit 13, can not produce big strike note.
As shown in Figure 5, opening device 1 of the present invention, after shuttle 10 rotation, upper thread ring passed through in making, the direction that opening device end 1a leaves from interior shuttle 10 was roughly along the Y-axis positive direction of interior shuttle contact site 10b.
The direction that postrotational reset direction and opening device end 1a of shuttle 10 leaves from interior shuttle 10 in this means antithesis, thereby the returning of interior shuttle 10 become easy (and prior art is equidirectional).Therefore, can make the over half of elliptical trajectory, act on engaging protrusion 10a is left from latch for printed circuit 12.In other words, the forward of the Y-axis of elliptical trajectory part (upper section of X-axis), promptly on the length direction of elliptical trajectory, the position part laterally of shuttle 10 can accomplish 10～50% in opening device end 1a leaves.Therefore, as shown in Figure 3, can guarantee that the upper thread ring has the sufficient time (interior shuttle blocking part) between the engaging protrusion 10a and latch for printed circuit 12 of interior shuttle 10 to pass through, and, as shown in Figure 4, can guarantee that upper thread has time enough to pass through between opening device end 1a and interior shuttle contact site 10b.
In contrast to this, by the explanation that conventional example shown in Figure 7 is done as can be known, the direction that postrotational reset direction and opening device end 20a of shuttle 27 leaves from interior shuttle 27 in it is equidirectional.Therefore, when the stroke of opening device is longer,, then will shorten its action time if reduce the distance that acts on interior shuttle contact site.Therefore, engaging protrusion 27a shortened with the time that latch for printed circuit 29 keeps separating, and the time of passing through of upper thread is hard up.And when the stroke of opening device more in short-term, though opening device end 20a act in the time lengthening of shuttle contact site 27b, the distance of shuttle contact site 27b in can not fully guaranteeing to leave.
In addition, opening device of the present invention is set like this, and promptly as shown in Figure 6, the angle when spur 9a overlaps with eedle drop point 11a in addition is as 0 degree and the anglec of rotation of shuttle in the scopes of 250～290 degree the time can make the upper thread ring by opening device end 1a.In the time of in being in above-mentioned angular range, opening device end 1a and interior shuttle 10 the two interval on Y direction must be set at the distance that at least the upper thread ring is passed.And, in the time of in above-mentioned angular range, by being set at, opening device end 1a on elliptical trajectory, arrives apart from interior shuttle 10 position (the P point among Fig. 5) farthest, can accomplish that P point to the distance of interior shuttle is minimum, therefore, can make the elliptical trajectory minimum that opening device end 1a is described, make the peripheral structure compactness of shuttle.
Want to satisfy above all conditions, the two the line and the angle theta of the center line of interior shuttle guid arm 2 of the linking part center and opening device end of shuttle guid arm 2, interior shuttle guiding connecting rod 3 is 40～70 to spend in can making.
At last, be that the 2nd form of implementation of opening device of circular trace and the difference of above-mentioned form of implementation describe with regard to the movement locus of opening device end in conjunction with Fig. 8.
This opening device 1 ' be fixed on the rotating shaft 15 that driven by not shown drive source and rotate.As this drive source, for example can make drive source with the shuttle axle equally with above-mentioned form of implementation.At this moment, via gear etc. same rotating speed is passed to rotating shaft 15 from the shuttle axle.
This opening device 1 ' act on the interior shuttle 10 owing to describe the circus movement track with the opening device end, so the strike note of shuttle contact site 10b is compared with the opening device of above-mentioned form of implementation to some extent and is increased in opening device end 1 ' a bump, but opening device end 1 ' a and the direction of leaving after interior shuttle contact site 10b contacts, be similarly along the direction of interior shuttle contact site 10b with above-mentioned form of implementation, therefore, not only can guarantee that the upper thread ring has enough nargin by the time of interior shuttle blocking part (the engaging protrusion 10a of shuttle 10 and the part between the latch for printed circuit 12 in being equivalent in the above-mentioned form of implementation), but also can guarantee that upper thread has time enough to pass through between opening device end 1 ' a and the interior shuttle contact site 10b.
In conjunction with Fig. 9～Figure 13 the 3rd form of implementation of Sewing machines opening device of the present invention is described.
As the open system of the 3rd form of implementation, near the opening device 1 of interior shuttle guid arm 2, link the swinging end that the interior shuttle guiding connecting rod 3 that is supported swingably by interior shuttle guiding pitman shaft 6 is arranged swingably by pin 7.
Interior shuttle guiding pitman shaft 6 is provided with a plurality of.Connect apertures 3a, 3b on the interior shuttle guiding connecting rod 3, that link with interior shuttle guiding pitman shaft 6 also are provided with a plurality of.Connect apertures 2a, 2b on the interior shuttle guid arm 2, that link with interior shuttle guiding connecting rod 3 also are provided with a plurality of.
As shuttle, generally select for use corresponding to the sew cloth kind of material and the kind of used suture and can obtain the shuttle of best upper thread ring by the time.Because various shuttles, the phase place of its eccentric cam 5 etc. has delicate difference, and therefore, even carry out the binding of each parts with same form, the movement locus of opening device end 1a also changes to some extent, can not obtain optimum efficiency.For this reason, can be by selecting certain combination (example of diagram has 8 kinds of combinations) of above-mentioned a plurality of [interior shuttle guiding pitman shaft 6,6], [connect apertures 3a, 3b], [connect apertures 2a, 2b] for use, to obtain movement locus corresponding to the ideal opening device end 1a of used shuttle.Fig. 2～shown in Figure 4 is the example of its combination.
In conjunction with Figure 13, a plurality of connect apertures with interior shuttle guiding connecting rod 3 are coupled together and the form of implementation that forms slotted hole 3c describes.Adopt this structure, the fixed position of interior shuttle guiding pitman shaft 6 can be set on the optional position of slotted hole 3c, therefore, compare, can carry out more meticulous adjustment with a plurality of connect apertures 3a, 3b are set.
At this moment, interior shuttle guiding pitman shaft 6, be with under the nut 15 at the slotted hole 3c place of shuttle guiding connecting rod 3 in upper and lower being configured in, the state that tubular band stepped screw 16 passes, be fixed on the installation ground B by screw 14, and fixing following carry out of interior shuttle guiding connecting rod 3 on interior shuttle guiding pitman shaft 6.That is, shuttle guiding connecting rod 3 moves with respect to interior shuttle guiding pitman shaft 6 along slotted hole 3c in making, and on optional position nut 15 is tightened on the tubular band stepped screw 16 and is fixed.
In conjunction with Figure 14, the 4th form of implementation of Sewing machines opening device of the present invention is described.This opening device major part is also identical with the 3rd form of implementation, only difference is described.
The feature of this opening device is that interior shuttle guiding pitman shaft 6 is provided with eccentric axial portion 6a, when shuttle was guided on the pitman shaft 6 in interior shuttle guiding connecting rod 3 was fixed in, and some the fixing among optional majority connect apertures 3a, the 3b, this point does not have different with the 1st form of implementation.Therefore, some advantages of fixing of this opening device in having optional majority connect apertures 3a, 3b, also has following advantage.Promptly, the eccentric axial portion 6a of interior shuttle guiding pitman shaft 6 that will be in some connect apertures 3a, 3b is fixed to when ground B being installed going up by screw 14, in can screwing by instruments such as screwdrivers the head of shuttle guiding pitman shaft 6 and change arbitrarily in shuttle guiding connecting rod 3 with respect to the position of eccentric axial portion 6a.Thus, can obtain identical with the 1st form of implementation, the effect of setting the fixed position of interior shuttle guiding connecting rod 3 on interior shuttle guiding pitman shaft 6 by slotted hole 3c arbitrarily shown in Figure 5.That is, can carry out trickle adjustment and obtain the movement locus of desirable opening device end 1a.
Because the present invention as above constitutes, so have following effect.
That is, shuttle is to the opposite spin of outer shuttle direction of rotation the time in ordering about, and the actuating quantity of the internal shuttle contact site of opening device is little, and speed of action is low, and therefore, when having that fixedly the technical scheme of opening device similarly plays a role, sound is minimum with existing.In addition, because the actuating quantity of the internal shuttle contact site of opening device is little, the oscillating quantity of shuttle reduces in making, bottom line tension is stable, and its result can form good seam mark.And, can the elongated surfaces wire loop time of stable opening during by opening device end and Nei Suo blocking part.And component number is same as the prior art, and manufacturing cost also is identical degree, and operability does not have different with prior art yet.
Particularly, because it is available to be provided with a plurality of interior shuttle guiding pitman shafts, and being provided with a plurality of and interior shuttle on interior shuttle guiding connecting rod, to guide the coupling position that pitman shaft links available, therefore, and corresponding, the best opening device end movement locus of shuttle that can obtain Yu be adopted.
