Abstract
The sewing machine is provided with a knot forming part for forming a knot of a needle thread and a cutting part for cutting the needle thread. After the end of a series of sewing work, with the needle thread stretched between a piece of cloth and a needle, a knot of the needle thread is formed by the knot forming part. Subsequently, the needle thread is cut just under the knot by the cutting part to provide the knot at the sewing start side end part of the needle thread. In the case of again starting sewing with the sewing machine, the occurrence of a skip stitch and a bird's nest state can be prevented by the knot.
Description
This invention relates to a kind of Sewing machines and uses the bind of this kind Sewing machines.
Generally speaking, suture needle is being carried upper thread and is being penetrated in the object to be sewn, for upper thread and bottom line are knitted together mutually, has the bottom that the shuttle of bottom line or upper thread that looper will come out are pulled to object to be sewn in it from object to be sewn.Thereby along with the feeding of object to be sewn, the mutual cooperation campaign of suture needle and shuttle or looper forms stitching continuously, thereby object to be sewn is stitched together.
By accompanying drawing 8 (a), 8 (b), 8 (c) and accompanying drawing 9 illustrate the shortcoming that common bind exists.
Fig. 8 (a) has represented to be placed on two object to be sewn 1 and 2 and suture needle 14 and pass the upper thread of suture needle pinprick 14a of suture needle 14 bottoms.Suture needle 14 pushes away is being with upper thread 10 to move downward and pass object to be sewn, is carrying upper thread 10 when suture needle later on again to lowest point and is moving upward.Just in this moment, the end 10b that is stretched in the upper thread between object to be sewn and the suture needle 14 is loosened, and the upper thread that loosens just forms a coil 10a, just shown in accompanying drawing 8 (b).
In order to allow bottom line in the shuttle by coil 10a and upper thread 10 formation coils, the pinhock 5 of shuttle has hooked coil 10a, yet when first coil of formation began, upper thread end 10b was by hook 5 downward tractives, sometimes the end of a thread part 10b can be drawn out object to be sewn 1 and 2, shown in Fig. 8 (c).This is because upper thread cephalic par 10b rests in the object to be sewn and do not have other any means can resist the pulling force of hook 5, shown in Fig. 8 (b).
Therefore, just shown in 10c among Fig. 9, upper thread is not knitted mutually with bottom line and is in the same place, thereby just defect is jumped in formation.When object to be sewn 1 and 2 was fed, the upper thread end 10b (shown in Fig. 8 c) that passes object to be sewn just was clipped between object to be sewn 2 and the needle plate 7.
Begin part from first coil and extend the upper thread head 10b come and bottom line 17 at object to be sewn 17 following mutual mats.Fig. 9 is shown tangles relatively mutually than orderliness, and is actually suture mat completely.
Like this, in common bind, have following shortcoming, begin part at seam trace circle exactly and can see jumping defect and entanglement phenomenon.This shortcoming is without any the pulling force of means antagonism to shuttle direction hand-pulled noodles line 10b because of upper thread end 10b.These problems such as jumping defect and entanglement, can be found in the formed seam mark of Sewing machines that various use upper threads 10 and bottom line 17 are sewed.These problems even also be present in the formed chain-type stitch of the Sewing machines that only uses upper thread.
To be the sewing-machine foot that do not show by a this country be pressed in upper thread end 10b below the presser feet a kind of method that addresses these problems, thereby make upper thread end 10b can stop the top of object to be sewn, and this is one of them example.
Yet the shortcoming of this solution is to make upper thread end 10b begin part at seam trace circle to extend oversizely, and also must carry out the extra work excessive thread ends part of going to prune away after sewing finishes.
It also has the another one shortcoming simultaneously, is that example illustrates with the sewing buttons, and this situation Sewing machines does not need bottom line.Specifically, adjusting the upper thread tension controller can make upper thread head 10b just remain between button and the object to be sewn.Yet upper thread head 10b can not be in identical position reliably, and its can extend out in the button or pass object to be sewn.This is because upper thread head 10b portion comes balance such as the top pulling force of having said that comes from object to be sewn bottom without any means.
A kind of Sewing machines and a kind of bind that adopts this Sewing machines have been the purpose of this invention is to provide.In order to solve upper thread head this problem of means without any the opposing pulling force, Sewing machines of the present invention can make the upper thread end be cut by the material of being sewed and hold.
According to a first aspect of the invention, the bind of this this Sewing machines of use is characterized in that at the upper thread head end locking thing (Capture) being arranged, and upper thread just can be stopped by plane object to be sewn like this.
Specifically, be exactly locking thing, thereby make the upper thread head-end location not move by object to be sewn blocking surface the end of a thread end.
When using the Sewing machines work of upper thread and bottom line at the same time, the crotch of shuttle is when the hand-pulled noodles line of needle plate below, thereby the upper thread head can not resembled the motion of shuttle direction by the object to be sewn surface barrier, has therefore just prevented the appearance of seam defect.
And, can not occur tangling yet, just be not pulled to shuttle on one side because the upper thread head end is basic.
With regard to Sewing machines scope of the present invention, the Sewing machines that the suture needle of any employing zone face line is sewed to plane object to be sewn can both solve the appearance of float and entanglement, specifically, these Sewing machiness only comprise the Sewing machines with a upper thread sewing, the Sewing machines of working together with upper thread, bottom line and shuttle or looper etc.
In only using the Sewing machines sewing process of upper thread, original upper thread head is located unfixed problem with respect to the seam thing and is solved the while and also eliminated the entanglement phenomenon.The present invention brings any restriction can for seam mark style.
The single line head broken into knot or a metal or a wood or some synthetic resin or single thread be adhered on the line or with linear system together, can play the effect of locking thing.Be coated with on line sclerosis synthetic resin also can be as the locking thing.
If it has liquid synthetic resin enough big viscosity single line can be fixed on above the object to be sewn also can to do the locking thing.
According to second aspect of its invention, use upper thread and bottom line to participate in the bind of the Sewing machines of sewing simultaneously, it is characterized in that, after each sewing, can make a call to a toe-in in one of the upper thread that passes pinprick.
Specifically, except sewing for the first time, on upper thread, can also form other locking tieing.Thereby, just stoped the appearance of line defect and entanglement.
After beginning sewing, one section its tension force of upper thread that is between object to be sewn and the suture needle is not tight, so be easy to catch it and make a call to a knot on top.Here used a kind of device of not knowing to come on upper thread, to tie a knot and cut off suture.
According to a third aspect of the present invention, this Sewing machines is characterised in that, a reciprocating motion of suture needle is brought the upper thread head end into object to be sewn, can stitch a locking of the upper thread formation thing that stretches between thing and the suture needle so that near the locking thing of upper thread that makes a what pass pinprick forms device.
Specifically, form at the locking thing and just to begin to sew after forming a locking thing on the upper thread that device passing suture needle, the effect of this method is identical with first aspect of the present invention.
At the device of tiing a knot on the single line or will coat a small pieces metal of stickum in advance or a small pieces synthetic resin or small pieces are wooden or an one thread adheres to the device on the upper thread or above-mentioned material is provided with an otch in advance, the device that it and an object are fastened can be used as locking thing formation device then.
According to a fourth aspect of the present invention, the Sewing machines that this kind uses upper thread and bottom line to work simultaneously, it is characterized in that it has a locking thing to form device and shear plane line apparatus, this device is installed near passing by that section upper thread of suture needle eye, the locking thing forms device and will be stretched in upper thread between object to be sewn and the suture needle and make a call to a knot and cutting off upper thread by cutting facility near the place of knot then, so that after having sewed, toe-in is stayed on the one section upper thread that passes pinprick.
Specifically, just as second aspect of bind of top said use Sewing machines of the present invention, one section upper thread that knotting device will stitch between thing and the suture needle is made a call to a knot, cutting facility is being cut off upper thread near the place of knot then, so just knot can be stayed the head end of upper thread, be convenient to next sewing action.
Therefore, make a call to a knot at the upper thread head end and can stop appearance seam defect and entanglement when the seam mark begins.And the above any one device of crossing can be used as knotting device, and shear well known already also can be used as the upper thread clipping apparatus.

For instance, Japanese Utility Model publication sho.44-27164 number this knotting device is disclosed.
About this point, comprise that as this Sewing machines of representing among Fig. 1 one can carry the suture needle 14 that upper thread 10 thrusts object to be sewn 12, one can swing up and down the shank 15 of pin 14, one can take out the suitable take-up steel wire 16 of stringing, one can knit bottom line 17 and upper thread 10 shuttle (not marking) together as shown in Figure 7 below object to be sewn 12, one can be with hello the dog (not marking) of object to be sewn 12 feedings, one places the sewing and the plate 18 of sewing piece 12, one needle plate 7 and that can allow sewing needle 14 pass object to be sewn 12 can fully be adjusted the tension control mechanism 20 of upper thread 10 with respect to the tension force size of bottom line 17, so that upper thread 10 after crosslinked and bottom line 17 are embedded in the middle of the object to be sewn 12.
Knotting device in this embodiment comprises, as shown in Figure 2, one knotting part 21 as locking thing formation device, one can catch upper thread 10 with it scissors part 22 of cutting off between knot 10 and object to be sewn 12, one drives the drive unit (not shown) of knotting part 21 and scissors part 22, the outer sleeve 23 (allowing in the inner sleeve 23a knotting part 21 and scissors 22 parts to move up and down in overall as one) that inner sleeve 23a is arranged in one, a fixture 24 and that outer sleeve is fixed on the frame is controlled the control device (not shown) of whole knotting part 21 and 22 actions of scissors part by the drive unit of above-mentioned mistake.
Knotting part 21 comprises that one first grabs line bar 21a and second and grabs line bar 21d.First grabs line bar 21a and second, and to grab line bar 21d all be not only long but also thin plate, and in order correspondingly to become hook 21b, a 21B at a capitiform separately, they all have a gap 21c, 21f respectively.
First grabs line bar 21a and second grabs line bar 21d and is superimposed with each other together, and hook 21e prolongs one section from hook 21b.In other words, second grab line bar 21d and grab the line bar corresponding to first and advance one section.
Knotting part 21 rotatably is loaded in the inner sleeve 23a, and inner sleeve 23a is installed in the outer sleeve 23 with sliding type.And it all is slidable in inner sleeve 23a that each of knotting part 21 is grabbed the line bar.
Two spinning movement and sliding actions of grabbing line bar 21a and 21d of controlling organization control that the top was said.
At fixing blade 22a edge the edge of a knife is arranged.The blade portion of the edge of a knife position what of movable blades 22b itself and fixed blade 22a is divided on the opposed edges.

When knotting part 21 when pushing upper thread 10 to scissors part 22, upper thread 10 is just partly guided and finally makes upper thread 10 to enter space between spring 22c and the blade 22a by the perk of spring 22C head end, so that upper thread is gripped firmly.
In addition, inner sleeve 23a also has one the 3rd drive unit (not shown) in addition, be used for outside cutting part 22, movable blade 22b being driven, more than the said controlling organization of sewing on the platform that be installed in, control the motion of whole knotting device 13 by two electric wire 23b and two electric wire 23c.
Article two, electric wire 23b transmits the motion of signal controlling inner sleeve with respect to outer sleeve, and control first is grabbed line bar 21a and second and grabbed the motion of line bar 21d with respect to inner sleeve 23a.Article two, electric wire 23c transmission signal controlling first is grabbed line bar 21a and second and is grabbed rotatablely moving of line bar 21d, and control scissors part 22 is cut off upper thread.
The bind that a use comprises the Sewing machines of above said knotting device 13 will be described now.
What at first, Fig. 2 (a) illustrated is the state of Sewing machines before once upper thread is not being cut later in sewing again.
Here, inner sleeve 23a advances to upper thread 10, shown in Fig. 2 (b), this be for allow scissors part 22 movable blades 22a and grab wire spring 22c space between them and grip upper thread 10, the part of tiing a knot then 21 stretches from inner sleeve 23a, catch upper thread 10 so that grab hook portion 21b and the 21e of line bar 21a and 21d, final, the knotting part 21 of hooking line 10 returns to position at first again.
Shown in Fig. 3 (a) is the vertical view of scissors part 22 shown in Fig. 2 (b).Said as the front, as inner sleeve 23a during towards upper thread 10 motions that are stretched between seam thing 12 and the suture needle 14, upper thread 10 be pushed into fixed blade 22a and grab the space between the wire spring 22c and be placed on fixed blade 22a and movable blades 22b between, then, shown in Fig. 3 b, knotting part 21 in sleeve 23a, turn round 180 ° so that upper thread 10 in order to form circle 10a quilt grabbed and rolled a week on line bar 21a and the 21d.
First grabs line bar 21a along moving towards the direction of inner sleeve 23a, while second grabs line bar 21d and moves along deviating from outer sleeve 23a direction, shown in Fig. 4 (a), so that when the revolution of knotting part 21, enter space between hook 21b and the 21e from circle 10a to the upper thread the suture needle 10 shown in Fig. 4 (b).
First grabs line bar 21a deviates from the motion of inner sleeve 23a direction, while second grabs line bar 21d and moves towards inner sleeve, so that between the two edges of 21b and 21e, catch upper thread 10, grab line bar 21a and grab line bar 21d and turn round 180 ° again, then inner sleeve 23a is towards the motion of outer sleeve 23 directions, so that hook 21b and 21e are pulled out outside the coil 10a.
Shown in Fig. 5 a, grab line bar 21a and 21d and catch upper thread 10 part adjacent, and it is pulled out in the middle of circle 10a with coil 10a.When grabbing the line bar when catching upper thread 10 to move with inner sleeve 23a, coil 10a can tighten round that section upper thread of extracting out from circle, because coil 10a is positioned at two devices that produce friction effects, promptly upper thread tension control mechanism 20 and grabbing between the wire spring 22c finally forms toe-in 11.
In order to allow toe-in 11 stay to pass the head end of the upper thread 10 of pinprick, movable blade 22b is driven and action takes place and cuts off upper thread 10.Part 21 and the scissors part 22 of tiing a knot this moment is mutually from must be far away; This is the process of tiing a knot for convenience of explanation, and in fact, for the ease of cutting off upper thread 10 near the place of knot 11, they are to be close to configuration mutually.
Sewing machines is cut off upper thread 10 after sewing finishes, sewing finishes thereby make once, and Sewing machines is then prepared sewing next time.When object to be sewn 12a and 12b were placed on suture needle 14 times, next sewing process began, just shown in Fig. 6 (a).
When sewing needle 14 penetrates object to be sewn 12, thereby upper thread 10 and can not pass from object to be sewn because the knot 11 of head end can be caught and can rest on above the object to be sewn by object to be sewn.
In when sewing, when moving downward, suture needle 14 moves upward after arriving its minimum point, and one section upper thread 10 between knot 11 and pin 14 is slacken correspondingly, and the line after loose can form coil 10b.
Bottom line 6 is for crosslinked together with upper thread 10, and gripped by shuttle, catches coil 10b by the hook 5 of shuttle, and the shuttle of possessing bottom line 6 is passed coil 10b.
As top described mistake, when the hook 5 of shuttle hooks coil 10b, the cephalic par branch of upper thread 10 moves downward, and shuttle can pass coil 10b, yet because the knot of being beaten 11 enough makes the upper thread head end can not pass object to be sewn forever greatly.Therefore, beginning part at first coil does not occur with regard to not having to jump defect and tangle.
Material feeding unit, suture needle 14 and shuttle three's the mutual coordinated movement of various economic factors make with upper thread 10 and bottom line 17 two sheet material 12a and 12b to be stitched becomes possibility.
As top said mistake, when the hook 5 of shuttle hooked coil 10b, the head portion of upper thread 10 is hauled to be moved downward, and shuttle passes circle 10b, yet, because knot 11 is very big, thereby make the upper thread head forever can not be by object to be sewn 12.Therefore, defect and entanglement just can not appear jumping in the beginning part at first coil.
And because the upper thread head end can not be pulled to one side of following shuttle, tangling also can disappear.
With regard to the scope of application of Sewing machines of the present invention, any can the Sewing machines that plane seam thing stitches all can being used with the suture needle that is installed with line, specifically, this Sewing machines can comprise the Sewing machines that only needs upper thread, need the Sewing machines of upper thread and bottom line and shuttle or looper simultaneously.
In the Sewing machines sewing process of demand side line sewing only, the problem that the upper thread head end can not be fixed its position with respect to object to be sewn is solved, and tangling does not simultaneously come across this kind sewing process yet.The present invention does not have opposite joint mark decorative pattern to bring any restriction yet.
With single line make a call to one the knot or with a wood, metal, some synthetic resin or a yarn adhere to or are tied on the single line, or the like these can play the locking thing effect, after coating the hardening of high viscosity synthetic resin on the single line, also can play the locking thing effect.
If the synthetic resin of liquid has enough viscosity upper thread can be adhered on the object to be sewn, also can play the effect of locking thing.
In the present embodiment, after having stitched with upper thread 10 and bottom line 6, knotting device 13 can be made a call to a knot 11 on upper thread, yet, when the operator changes the another one upper thread, he can be placed in the head end of the upper thread that newly changes and grab between wire spring 22c and the fixed blade 22a, handles Sewing machines then and has knotting 11.
If the knot of being beaten 11 is big inadequately with respect to the eyelet of object to be sewn, knot 11 can pass through object to be sewn.In this case, 10a is just enclosed in the motion or increase the revolution number of times of grabbing the line bar and twine number of times to increase upper thread of repeating to tie a knot, and institute is tied a knot 11 become enough greatly.
