The eedle of this Sewing machines in cylinder bed falls the left side at place, and promptly the left side of the position that moves up and down of 2 eedles 5,6 is provided with first cutter 11 of following formation.First bears the rear portion that cutting knife 13 usefulness screws 12 are fixed on cylinder bed 1.This first bear cutting knife 13 the front end edge needle plate below extend to eedle and fall near the place.First billhook, 16 usefulness stepped screws 14 are installed in rotation on the front portion a little partially of cylinder bed 1.On the leading section of this billhook 16, forming hook 15 (toe-in closes mechanism).In addition, bear first and setting up holddown spring 17 on the cutting knife 13.Since the rotation hook 15 of first billhook arrive first bear cutting knife 13 front ends below the time, holddown spring 17 with hook 15 be pressed in bear cutting knife 13 below.Rearward end at this billhook is provided with slotted hole 18.
At the left end of cylinder bed 1, cylinder 19 has been installed, on the piston rod 20 of this cylinder 19, with screw 22 adjustable positions fixing and making moving plate 21.Doing to be provided with pin 23 on moving plate 21 upper surfaces.This pin 23 is entrenched in the slotted hole 18 of first billhook 16.In addition, cylinder 19 is connected to (diagram is omitted) on the source of high pressure air by managing 24.Because the action of air pressure from source of high pressure air is advanced and retreat the moving plate 21 of doing that is fixed on the piston rod 20 in the direction of arrow A.Because do the advance and retreat motion of moving plate 21, first billhook 16 rotates in the direction of arrow B around stepped screw 14.
Fall the right side at place at the eedle of cylinder bed 1, be provided with second cutter 25 of following formation.This second cutter 25, as the wire cutter of recording and narrating in the fair 5-68280 communique of spy (U, S, Pat, 4,726,305), changeable be position of readiness (Fig. 8) near the mobile alignment of the active position of the mobile alignment of lopping device 3 and disengaging lopping device 3.Second billhook 28 is advanced and retreat between progressive position and going-back position above the 3b of sheet portion of lopping device 3 in above-mentioned active position and is moved.On the leading section of this second billhook 28, be set up in parallel two hooks 26,27.At above-mentioned active position, be provided with second immovably and bearing cutting knife 30.Bear second and to have set up holddown spring 29 on the cutting knife 30.By this holddown spring 29 second billhook 28 is crimped on second and bears on the cutting knife 30, and bear cutting knife 30 co-operatings cut-out line at the going-back position and second of second billhook 28.This second billhook 28 is driven by drive units such as solenoid not shown in the figures and cylinders.
The method that prevents that sewing thread unclamps when with Fig. 2 to Fig. 8 sewing termination of the present invention being described.As shown in Figure 2, on this Sewing machines, cloth W is carried by the direction of work feed teeth directional arrow F.On the cloth W that is transferred by being through the stitch S that eedle line 8,9 on left and right sides pin 5,6 and the lopping device 7 and looper thread 10 form needle tracking form 406 respectively.As shown in Figure 2, during near the sewing termination of cloth, eedle 5,6 roughly be in top dead-centre, lopping device 3 roughly be in left dead point, when being progressive position, cylinder 19 actions are rotated billhook 16 to clockwise direction.Because the rotation of first billhook 16, forwards move from the rear of lopping device 3 top of the 3b of sheet portion of hook 15 crosscut lopping devices 3.Because should move, as shown in Figure 3, hook 15 colludes the looper thread 10 of linking the aperture 3e of lopping device 3 from cloth W.
Then, left and right sides pin 5,6 drops in the triangle of the line that 3b of sheet portion and eedle line 8,9 by looper thread 10, lopping device form.With the decline of eedle 5,6, lopping device 3 then falls back on right-hand from the preceding side shifting of eedle.As shown in Figure 4, looper thread 10 is combined and form long slightly circle 10L in the front of eedle 5 location by hook 15.After this, lopping device 3 limits through right dead point, be going-back position.It is mobile to advance to left at the rear side of eedle 5,6, and the limit holds with both hands with both hands and gets the new needle thread loop 8L that is formed by the eedle that rises again through bottom dead centre, 9L (Fig. 5 (a)).Be Fig. 5 (a) expression from roughly the advance state of 1 pin of the state of Fig. 2.The long circle 10L that is combined in looper thread on the hook 15 lopping device 3 slightly above, keeping its original state.
At this moment, because the action of cylinder 19, first billhook 16 is to counterclockwise rotating.Because the rotation of first billhook 16, hook 15 arrives the below of bearing cutting knife 13 front ends, cuts off the bound fraction that is attached to the looper thread 10 on the hook 15.At this disengagement phase, by the driving of drive unit not shown in the figures, second billhook 28, the second bears cutting knife 30 and holddown spring 29 is switched to active position, and meanwhile, 28 forward travels of second billhook are to left.Hook 26,27 thus, move to the left side (Fig. 6) that eedle falls the place along the top of the 3b of sheet portion of lopping device 3.
Then, when 28 setbacks of second billhook when right-hand, hook 26 catches on the looper thread 10 of linking lopping device 3 from cloth W, hook 27 catches on two needle thread loop 8L, 9L that link eedle from cloth W through the 3b of sheet portion of lopping device.Second billhook 28 is colluded under the bonding state on the hook 26,27 at each bar line, retreats mobile (Fig. 7) to right-hand.Then, two needle thread loop 8L, 9L that are in bonding state arrive second at hook 27 and are cut off when bearing on the cutting knife 30.
Be in the looper thread 10 of bonding state, because the setback of second billhook 28 is crooked at leisure.When this bending proceeded to a certain degree, the end of a thread 10e that has been cut off was by being formed on the final needle thread loop 8LL on the cloth, and 9LL is pulled out the right side.Second billhook 28, the second bears cutting knife 30 and holddown spring 29 is switched to position of readiness then.As shown in Figure 8, the end of a thread 10e side that is pulled out is clamped by hook 26 and holddown spring 29.That is to say, link residual very short of the end of a thread 10f of the looper thread on the cloth W.The end of a thread 10e of looper thread that remains in lopping device 3 sides is extracted among the 9LL by from final needle thread loop 8LL.So, the end of a thread 10f that has been cut off only otherwise from the needle thread loop 8LL of final left pin, extract, the sewing terminal of cloth just can not unclamp.
In the above-described embodiments, the long circle 10L that is attached to looper thread on the hook 15 lopping device 3 hold with both hands with both hands get needle thread loop 8L, 9L after, as shown in Figure 6, be cut off because the below of cutting knife 13 front ends is born in hook 15 arrival.Yet this cut-out can be walked half pin at the driving Sewing machines and carry out under the state of the going-back position of the progressive position arrival of lopping device 3 shown in Figure 3 lopping device 3 shown in Figure 4.Promptly the long circle 10L of looper thread be formed under the state hook 15 arrived bear cutting knife 13 front ends below cut off the bound fraction (Fig. 5 (b)) that is attached to the looper thread 10 on the hook 15.Hold with both hands with both hands with lopping device 3 and to get after new needle thread loop 8L, the 9L, make to be set up in parallel above the 3b of sheet portion of lopping device 3, to move to the left side that eedle falls the place at the hook 26,27 of the leading section of the 2nd billhook 28.So, become the state identical even under Fig. 4 state, cut into the long circle 10L limit of circle device line with Fig. 6.If the following method of Fig. 6 is carried out like that according to above-mentioned, the phenomenon that also can not unclamp at the cloth sewing terminal.
Above-mentioned double-thread overlock sewing machine, the going-back position of lopping device fall the right side at place at eedle.But, be the double-thread overlock sewing machine of the going-back position of lopping device, if the phenomenon that the mechanism that is equivalent to first cutter and second cutter is housed, also can unclamp at the cloth sewing terminal in the left side.In addition, though above-mentioned double-thread overlock sewing machine has two eedles is not limited thereto.Illustrate that with Fig. 9 to Figure 16 above-mentioned sewing thread unclamps second embodiment of the method for preventing.As shown in Figure 9, this Sewing machines is also carried cloth by work feed tooth 2 to arrow F direction, on the cloth W that is transferred, by being through the stitch Sx that eedle line 8x on eedle 5x and the lopping device 3x and looper thread 10x form stitched version 401 respectively.When sewing end of a period, eedle 5x near cloth roughly are in top dead-centre, when lopping device 3x roughly was in right dead point and is progressive position, billhook 16x was to counterclockwise rotating.Because the rotation of billhook 16x, forwards move from the rear of lopping device 3x the top of the blade portion 3xb of hook 15x crosscut lopping device 3x.Owing to should move, as shown in figure 10, on the hook 15x hook link the looper thread 10x of the aperture 3xe of lopping device 3x from cloth W.
Then, eedle 5x drops to by looper thread 10x, in the triangle of the line that the 3xb of sheet portion of lopping device and eedle line 8x form.With the decline while of this eedle 5x, lopping device 3x retreats from the front side shifting of eedle and to left.Drive Sewing machines and walk half pin, go to the going-back position of lopping device 3x shown in Figure 11 from the progressive position of lopping device 3x shown in Figure 10, looper thread 10x is combined on the forward position of eedle 5x and forms long slightly circle 10xL by hook 15.At this moment, because the action of cylinder (figure does not show), the first billhook 16x rotates as illustrated in fig. 12 along clockwise direction.Because the rotation of the first billhook 16x, hook 15x arrives the below of bearing cutting knife 13x front end, and the bound fraction that is attached to the looper thread 10x of hook 15x is cut off.
Subsequently, Yi Bian lopping device 3x limit through left dead point the rear side of eedle 5x advance move to right-hand, hold with both hands with both hands and get the new needle thread loop 8xL (Figure 13) that forms by the eedle that rises again through bottom dead centre.At this moment, the 2nd billhook 28x, the 2nd bears cutting knife 30x and holddown spring 29x is switched to active position, and meanwhile, the second billhook 28x is to right-hand forward travel.Thus, hook 26x, 27x moves to the right side (Figure 14) that eedle falls the place along the top of the 3xb of sheet portion of lopping device 3x.And when left was arrived in the second billhook 28x setback, hook 26x colluded the looper thread 10x that links lopping device 3x from cloth W, and hook 27x colludes the needle thread loop 8xL that links eedle from cloth W through the 3xb of sheet portion of lopping device.Colluded under the bonding state on hook 26x, the 27x at each bar line, the second billhook 28x is to left setback (Figure 15).Hook 27x one arrives second and bears cutting knife, is in bonding state needle thread loop 8xL and just is cut off.
Be in the looper thread 10x of bonding state, because the setback of the second billhook 28x is crooked at leisure.When this bending proceeded to a certain degree, the end of a thread 10xe that cuts off was pulled out the left side by the final needle thread loop 8xLL that is formed on the cloth.Then, the second billhook 28x, second bears cutting knife 30x and holddown spring 29x is switched to position of readiness.As shown in figure 16, the end of a thread 10xe that pulls out is clamped by hook 26x and holddown spring 29x.That is to say that link residual very short of the end of a thread 10xf of the looper thread on the cloth, the end of a thread 10xe that remains in the looper thread of lopping device 3x side extracts from final needle thread loop 8xLL.So, the end of a thread 10xf that has cut off only otherwise from the needle thread loop 8xLL of final left pin, extract, the sewing terminal of cloth just can not unclamp.
Though just do not described in detail about the driving of 1 pin of Sewing machines or half pin and the starting control of each cutter, can utilize the rotation control device of known motor of sewing machine and means such as control by the signal that is located at the revolution detector on the machine spindle.In addition, the front end 10e of the looper thread that is cut off and clamp if 10xe is very long, can make hook 26, and 26x arrives second billhook 28, and 28x cuts off front end 10e, the 10xe of looper thread.
As mentioned above, according to the present invention,, only link the final needle thread loop of looper thread head on being formed on cloth of lopping device and extract, so can prevent reliably that looper thread from unclamping from the terminal of stitch because among the looper thread head that cuts off.And, according to the present invention, because it is short to link the looper thread head of this sewing terminal, so, even do not append the operation of winning, also can obtain sewings of high grade to the end of a thread.
