The specific embodiment
Fig. 1 and Fig. 2 have to implement the amplification plan view that idle loop of the present invention sews up the major part of the approximate three-dimensional map of overlock machine of the used apparatus for sewing a thread chain into a seam of method and apparatus for sewing a thread chain into a seam.In addition, in apparatus for sewing a thread chain into a seam of the present invention, putting on prosign with the inscape that traditional apparatus for sewing a thread chain into a seam of Figure 11～shown in Figure 13 is general, omit its explanation or simplification, mainly is to be that the center describes with the structure different with conventional apparatus.
Among Fig. 1, the 11st, the transverse slat of overlock machine M, on the assigned position of this transverse slat 11, fixing needle plate 3 with fall pin portion 1 and sealing formation usefulness claw 2 shown in Figure 2, form with near the front side the cardinal extremity of claw 2 at sealing, it is disconnected with cutting knife 20 (only represent movable upper cutter portion on the drawing, omitted fixed down cutter portion) to be provided with the sewing end-grain cutting.Again, top at needle plate 3, except the presser feet 4 that is fixed with idle loop paw 6 described later, also be provided with sewing sensor (omitting diagram), this sewing sensor is to by being supported on the shank 13 on the Sewing machines base plate 12, pin folder 13a and with respect to the described pin portion 1 that falls drive up and down reciprocating motion freely pin 14 and needle plate 13 above have or not sewing to detect, when having sewing (dark state), the rotation of permission Sewing machines, simultaneously, at the right rear side of making direction of advance X, dispose the idle loop shearing devices (because of being technique known with respect to needle plate 3, the Therefore, omited diagram), and, right side at needle plate 3, dispose and drive swing idle loop suction tube 5 freely around fulcrum gyroaxis 15, again in the front of this idle loop suction tube 5, configuration pushes guider 17 by the idle loop that erecting bed 16 is installed on Sewing machines base plate 12.
As shown in Figure 3, described idle loop suction tube 5 around fulcrum gyroaxis 15, can drive in following 3 positions swing freely, promptly after cutting off by the idle loop shearing device, the idle loop A that accepts to be blown back sucks the 1st position of maintenance; Sucking under the state that keeps this idle loop A, retreating the sealing that is rocked to described needle plate 3 and form with near disconnected the 2nd position of carrying out standby of the sewing end-grain cutting of the front portion claw 2 cardinal extremities with near the position of cutting knife 20; The action beginning of sewing up along with idle loop A further retreats swing to the direction Y opposite with making direction of advance X from the 2nd position, idle loop A is introduced the 3rd position in the sealing of making starting end We of follow-up sewing W.
Again, at the side end of described presser feet 4, but fixing position, left and right sides adjustment idle loop paw 6 freely, as shown in Figure 4 and Figure 5, this idle loop paw 6 comprises: relatively fall pin portion 1 and the claw 2 of needle plate 3 are for dwindling the fall 6a of pin portion and the claw 6b of similar shape; To divide a word with a hyphen at the end of a line in the inside of presser feet 4 side, have the idle loop guide part 6c on inclined plane by the idle loop A landing of side to the pin portion 1 that falls, 6a of idle loop suction tube 5 drawings; And the groove 6d that landing is divided a word with a hyphen at the end of a line and led in the chimeric maintenance of the idle loop A of the inside side, with the introducing towards the sealing S of follow-up sewing W of this idle loop A by this idle loop guide part 6c.In facial 6e, 6f are led in the introducing of these idle loop paw 6 the insides with a pair of room of the both sides relative position of gathering sill 6d away from the room of side edge one side of sewing W lead facial 6e the fall pin portion 1 nearest, 6a and be indexed to and the opposite left side of sewing W side edge with respect to the side edge of gap material W.
And, described idle loop pushes guider 17 and constitutes by fixedly remaining on the cylinder 18 on the erecting bed 16 and pushing guide 19 with the fixedly connected idle loop of the piston rod 18a front end of this cylinder 18, push the front end of guide 19 at idle loop, be formed with the roughly idle loop hook 19a of portion of V word shape.This idle loop pushes guider 17 shown in the solid line of Fig. 1 and Fig. 6, this idle loop pushes guide 19 and normally retreats the oblique upper right side position of standby to needle plate 3 and presser feet 4, with from the 2nd position of described idle loop suction tube 5 to the mobile interlock of the swing of the 3rd position, arrow as Fig. 1, shown in the dotted line of Fig. 2 and the solid line of Fig. 7, by moving to the Z turnover, the idle loop hook 19a of portion of front end is introduced pin portion 1 to the oblique lower left in the stretching, extension path that intersects at idle loop A, the part of the idle loop A of side pushes idle loop on the idle loop paw 6 facial 6e side that leads its displacement is moved in front of the 6a.
Below, with reference to the operating state variation diagram of Fig. 6 and Fig. 7 and the time diagram of Fig. 8, the idle loop of the apparatus for sewing a thread chain into a seam of the overlock machine of said structure is sewed up method make an explanation.
Move ahead the sewing finishing end of sewing at the time point that becomes non-detection (bright state) by sewing sensor, this sensor, the idle loop shearing device begins to suck, remaining idle loop is sucked, the thread-loosening device of known technology is ON simultaneously, loose ends continues to turn round on one side on one side, till the predefined number of handling the needle of overlock machine M, formed the idle loop of certain-length during this period.Set the number of handling the needle in case arrive, then Sewing machines M stops revolution, and described idle loop shearing device cuts off the idle loop that sucks, and the idle loop that will cut off simultaneously is towards blowing out in the opposite direction with suction side.Immediately standby is shifted to the 1st position in the idle loop suction tube 5 of the 2nd position of Fig. 3 then, and begin to suck, after the idle loop A that will blow out from the idle loop shearing device attracted to keep, swing moved to the 2nd position and carries out standby again, simultaneously, presser feet 4 rises with separating above the needle plate 3.Under this state, pedal is placed OFF, the sewing sewing finishing moves ahead.
Secondly, suction remains in the idle loop A of described idle loop suction tube 5 by moving to the swing of the 2nd position of this idle loop suction tube 5, be introduced into the front of the pin portion 1 that falls of needle plate 3, under this state, the follow-up sewing W of back has come on the needle plate 3, its make starting end We be in make direction of advance X go up with the roughly same line of the disconnected usefulness of sewing end-grain cutting cutting knife 20 on, in case by described sewing sensor (dark state), then presser feet 4 descends, top butt with needle plate 3, thread-loosening device becomes OFF simultaneously, removes loose ends, the form that formation can begin to make.
Under this state, in case pedal places ON, then Sewing machines M begins revolution, and sewing W makes the pin portion 1 that falls that beginning ora terminalis e arrives needle plate 3 towards making direction of advance X until this.During this period, the sealing that is wound on needle plate 3 forms and still to be wound onto on this claw 3 with the idle loop A on the claw 2.
Then, sewing W is towards making direction of advance X feeding, this sealing of making beginning ora terminalis e arrival needle plate 3 forms with near the position claw 2 front ends, when making beginning ora terminalis e when the disconnected size with cutting knife 20 of sewing end-grain cutting arrives the position of specific length, Sewing machines M stopped after the revolution stipulated time, described idle loop suction tube 5 moves to the 3rd position from the swing of the 2nd position simultaneously, and as shown in Figure 6, idle loop A is by the front side of drawing to fall pin portion 1,6a.Thus, idle loop A travels to the inside side by the idle loop guider 6c landing on the idle loop paw 6, is remained on the introducing of the inside with in the gathering sill 6d by chimeric.
Thereafter, idle loop pushes guider 17 start immediately, as shown in Figure 7, idle loop pushes guide 19 and moves towards the turnover of oblique lower left, the 19a of hook portion that the part of idle loop A pushes guide 19 front ends by idle loop thereupon is pushed into idle loop that displacement moves to gathering sill 6d one side who the is formed with idle loop paw 6 the insides facial 6e side that leads, then, keep being disengaged by the attraction of idle loop suction tube 5 with idle loop A.
And, in case the Sewing machines M after stopping to return to the rotation of regulation, thus, follow-up sewing W feeds towards making direction of advance X, begin to make, make the handling the needle of initial stage of beginning and be pushed into the side end of the idle loop A of the disconnected cut-out portion with cutting knife 20 of sewing end-grain cutting by this with sewing W, cut off by cutting knife 20, thread chain part after this cut-out is introduced among the sealing S that makes starting end of sewing W and sews up, but this moment, carry out displacement and move because the part of idle loop A is pushed into idle loop that idle loop paw 6 the insides the are formed with gathering sill 6d one side facial 6e side that leads, so as shown in Figure 9, a part of A1 that is introduced into the idle loop A among the sealing S of sewing W is sewed up by the needlework ny that forms sealing S.Like this, when sewings washing etc., even apply big power to sewing W, the idle loop A that also can prevent from reliably to be sewed up among the sealing S deviates from from sealing S, keeps the good surface appearance form all the time, and can guarantee original anti-off-line function when reinforcing seam.
Again, the number of handling the needle in basic when seam after above-mentioned idle loop sews up is at the time point that has arrived setting, and described idle loop pushes guider 17 and replys and move to the position, oblique upper right side shown in Fig. 1 solid line, and, idle loop suction tube 5 returns the 2nd position, and the idle loop of preparing next time sews up.
In addition; in above-mentioned example; the idle loop that pushes gathering sill 6d one side of idle loop paw 6 the insides as the part with the idle loop A facial 6a side that leads is carried out the device that displacement is moved; to use Fig. 1; the idle loop of Fig. 6 and structure shown in Figure 7 pushes guider 17 and is illustrated for example; but also but dual-purpose device shown in Figure 10 replaces above-mentioned device; promptly use eccentric cam etc. to make the position off normal of fulcrum gyroaxis 15; front end motion track when swing the 3rd position also will keep left than track shown in Figure 2 so that idle loop suction tube 5 is from the 2nd position, by this idle loop suction tube 5 part of idle loop A is pushed the idle loop facial 6e side that leads and carries out displacement and move.When adopting the structure of this displacement mobile device by idle loop suction tube 5 dual-purpose idle loop A, the idle loop that no longer needs to be arranged on the required large space in needle plate 3 right sides pushes guider 17, can reduce all costs of device and realize miniaturization.
Again, the idle loop that pushes gathering sill 6d one side of presser feet 6 the insides as the part with the idle loop A facial 6e side that leads is carried out the device that displacement is moved, except above-mentioned each example, also can be in the position, oblique upper right side of needle plate 3 and presser feet 4, setting has the nozzle that blows the idle loop function, make the air that blows out from this nozzle blow to idle loop A, perhaps in the position, oblique upper left side of needle plate 3 and presser feet 4, idle loop is set attracts mouth or turnover to retreat the mobile movable idle loop hooking part freely of driving, dependence attracts the idle loop sucking action of mouth by this idle loop or relies on hook introducing effect by the idle loop of idle loop hooking part, and a part that makes idle loop A moves to the displacement facial 6e side displacement of leading.
And in above-mentioned example, illustrated is double-needle cup seaming machine M, but also is applicable to single needle or 3 pin overlock machines, can obtain and above-mentioned same action effect.
