Description
Technical field
The present invention relates to a kind of rotating shuttle device that is used for Sewing machines, the rotating shuttle device that more particularly is used for Sewing machines, wherein a part that tilts is formed on first flange of peg or spindle so that the coiling amount of permission bottom line has significant increase and prevents broken string and kinking, and wherein, need not consider the to sew sewing velocity and the thickness of material, employing has the coupler body of the pinch wheels of single form, needn't change coupler body so that obtain good sewing quality, thereby the labour who has obviously reduced member cost and workload and be used to replace member.
Background technology
Generally in Sewing machines, a rotating shuttle device 100 that is used to supply bottom line is set.Rotating shuttle device 100 is set at the driving shaft 10 that is rotatably coupled to driving arrangement, and this device is made of the peg or spindle 40 that a coupler body 20, is contained in a bobbin case BC in the coupler body 20 and the bottom line of reeling thereon.Bobbin case BC comprises the bobbin case base 30 and the bobbin case main body 50 of accepting peg or spindle 40 from peg or spindle 40 outsides that are contained in the coupler body 20.
In the bottom of bobbin case base 30, a upright axis of a cylinder 31 that is provided with is arranged.Peg or spindle 40 can be rotatably set on the axis of a cylinder 31.A groove 21 is formed on the inboard of coupler body 20.A hook 22 is formed on an end of structure body 20.Near hook 22, form a groove 23 that has slow radius curve, so that bottom line contacts with groove 23 through groove 23 simultaneously.The outside at peg or spindle base 30 forms a rail portion 32, and its rail groove 21 that is inserted into coupler body 20 is so that bobbin case base 30 is set in the coupler body 20, and coupler body 20 also can rotate.Simultaneously, semicircle pinch wheels 25 by fastener for example bolting on half part of the Outboard Sections of coupler body 20 so that bobbin case base 30 can rotary setting and bobbin case base 30 can be inserted into wherein or from then on separate.Pinch wheels 25 has the opposite hook 25a of that be formed on coupler body 20 and a hook 22.Say further, thread guides 26 by fixture for example bolt removably be fixed on second half of coupler body 20 Outboard Sections, so that mutually continuous with pinch wheels 25.Thread guides 26 also has the opposite hook 26a of hook 25a of and pinch wheels 25.
Bobbin case base (base hereinafter referred to as) 30 integrally links to each other each other with bobbin case main body (hereinafter referred to as main body) 20 and forms bobbin case BC.Adjacent with bobbin case BC and be set at a support (not shown) on the sewing machine main body and be inserted in the recess 33 that is formed at base 30 so that location bobbin case BC, the bobbin case BC location that is fixed like this.Say further, near recess 33, form the through hole that sewing needle passes through when pin moves down 34.
Peg or spindle 40 comprises the wireline reel 41 of the bottom line of reeling thereon, is formed on first flange 43 and second flange 45 that is formed on wireline reel 41 other ends of an end of wireline reel 41.Simultaneously, the applicant has applied for the peg or spindle of an extension, and the peg or spindle of this extension further extends wireline reel 41 and has one separates flange 47, and the recessed portion that wherein has an inclined-plane is formed between first and second flanges 43 and 45.
Now, the operation of aforesaid rotating shuttle device will be described following.
When a Sewing machines is operated, coupler body 20 rotations, and simultaneously, the thread take-up tension lever (not shown) and the suture needle of upper thread move up and down.Between two refundings of coupler body, suture needle hooks bottom line once.Because the operation of yarn take-up, desirable length of yarn is drawn out so that the bottom line of preparing next time hooks operation.
Fig. 2 is the diagrammatic sketch that a bobbin case BC and peg or spindle 40 are omitted, so that illustrate when suture needle 2 moves down, and the state that upper thread 3 hooks on coupler body 20 by suture needle 2,, Fig. 3 illustrates the moment that upper thread is hooked by coupler body 20, and Fig. 4 is the side view of Fig. 3.
Say that further Fig. 5-10 illustrates sewing operation successively, each accompanying drawing a), b), c), d), e) and f) be the front view of rotating shuttle device, and a '), b '), c '), d '), e ') and f ') state that coupler body 10 is reversed is shown, make the bottom-up of coupler body 20 and be convenient to understand.
If Sewing machines is operated, upper thread 3 is moved down by the suture needle of threading.Simultaneously, upper thread is hooked downwards by hook 22, and simultaneously coupler body 20 rotates (with reference to Fig. 2-6) along with the decline of suture needle.Because seam 2a is formed on a side of suture needle 2, and threading can be hooked downwards by the hook 22 of coupler body 20 by the upper thread of suture needle, above operation can be done.At this moment, if the spacing between suture needle 2 and hook 22 is far, because upper thread 3 is not hooked on hook 22, sewing thread is omitted sometimes or sewing operation is not normally finished.If described spacing is too near, suture needle and hook 22 are piled up, and broken needle takes place.
As mentioned above, the upper thread 3 that is hooked downwards by the hook 22 of coupler body 20 so that form a circle that is used for looping bobbin case BC, upwards hooks bottom line 4 (Fig. 7-10) by thread guides 26 guiding of coupler body 20 thus.As mentioned above, upper thread 3 can looping bobbin case BC be because pulled out by thread take-up tension lever in upper thread 3 stroke in front with the reason that forms coil.
The length of the upper thread of being pulled out by thread take-up tension lever when thread take-up tension lever makes a round trip is consistent with the length of the needed upper thread of looping bobbin case BC when coupler body 20 turns around.If increase and the amount of bottom line has the capacity of the coupler body 20 of substantial connection, the length of the upper thread of being pulled out by thread take-up tension lever is short to and makes thread breakage.If length is oversize, the tension force of bottom line can not be held, and thus, bottom line is to lower swing and fluffy and disorderly fluctuation on sewing thread.
If the coiling amount of bottom line increases, the number of times of the replacement work of peg or spindle is reduced, and then improves job schedule.Yet if the size of bobbin case increases along with the increase of bottom line coiling amount, because the length of the upper thread of being pulled out by thread take-up tension lever is defined, the curtailment of upper thread is with the looping bobbin case.In other words, because the coil of the upper thread of short length can not looping bobbin case BC, upper thread is fracture just.The unique answer that solves described problem is the length that increases thread take-up tension lever.Yet because the foundation structure of the extensive compatibility of Sewing machines must be changed, it is practically impossible.
Upper thread is in sweep 36 fractures, wherein, as the coil of the upper thread thread guides 26 by coupler body 20 broaden in the both sides of base 30 and main body 50 (Fig. 8), during subsequently from base 30 disengagings (Fig. 9), maximum tension force is applied to upper thread, and wherein bottom surface 37 and vertical surface 35 contact with each other after the starting point of the rail portion 32 that is formed at base 30.
As another countermeasure as shown in figure 11, a bobbin case base 30 ' is provided, one of them sweep 36 is round, a meshed portion 38 forms by a part of cutting bottom surface 37, make the seizure of upper thread minimum, and a guide rail 39 also is formed at sweep 36 so that avoid catching of upper thread.
Yet in order to increase the coiling amount of bottom line 4, the bottom surface 37 of base 30 must extend to the outside so that increase spatial accommodation.Therefore, the opening of bottom surface 37 and the perforate part 38 between the vertical surface 35 becomes big.As shown in figure 12, the excircle of first flange 43 of peg or spindle 40 exposes by the opening of perforate part 38.
Say that further it is many more that bottom line is reeled on peg or spindle 40, first flange 43 and second flange or separation flange 37 are because the tension force of bottom line self is stretched over the wide more of the outside.
As mentioned above, because the opening of first flange 43 of the peg or spindle perforate part 38 by being formed on base 30 bottom surfaces is exposed, and is stretched over the outside by the tension force of yarn, first flange 43 of peg or spindle 40 and the vertical surface 35 of base 30 separate.As a result, a problem occurs, promptly upper thread is caught by first flange 43, and first flange 43 is stretched over the outside of the vertical surface 35 of base 30 with high rotation speed, and the coil of upper thread breaks away from and eventual failures from base 30.
Therefore, although upper thread can pass through sweep 36 safely, because upper thread is caught by first flange 43 of peg or spindle, it is limited to improve the coiling amount of bottom line.
Like this, because the bottom surface 37 of first flange 43 and base 30 rubs brokenly, a problem occurred, the bottom line that promptly is wound up on the peg or spindle 40 loosens brokenly, so bottom line twines or fracture.Say that further when the peg or spindle rotation, yarn leaves from the outside of first flange.And the end that separation flange 47 is stretched over the outside can collide with suture needle.
Simultaneously, the function of hook 25a that is arranged on the pinch wheels 25 of coupler body 20 be in the end the stage grip upper thread so that the tension force of the upper thread that passes through such as above-mentioned can being held.
As shown in figure 13, preferably, the upper thread 3 and the bottom line 4 that intersect at the central part of object 5a and 5b can be sewed.When upper thread 3 and bottom line 4 core at object intersects, as shown in figure 14, the sewing thread trace straight line that is in line.Such result is only just obtained when the tension force of upper thread and bottom line is consistent each other.
Yet if the tension force of upper thread 3 is not held, as shown in figure 15, upper thread 3 lets droop.If the overtension of upper thread 3, as shown in figure 16, upper thread 3 upwards loosens and bottom line 4 fluffy and disorderly fluctuations (flutteredroughly).
As mentioned above, the hook 25a of the pinch wheels 25 of coupler body 20 keeps the tension force of upper thread, and grips the yarn through the main body 50 relative with base 30, loosens upper thread with speed at different time points according to the thickness that is sewed object.
For example, if with the described object of sewing at a high speed, hook 25a must have long distance with long-time gripping upper thread.If described object is thinner, described hook 25a also must the long period keep upper thread.
Therefore, because the pinch wheels 25 of the coupler body 20 of adjustment of tonicity has a different structure according to all objects and sewing velocity, a problem then occurs, promptly the user must prepare the coupler body of so many kind, and replaces coupler body when sewing operation each time.Say that further because the hook 25a of pinch wheels 25 grips upper thread in the bottom side, tension force is to lopsidedness, and the sewing thread trace straight line that is not in line, as shown in figure 17.Therefore, another problem having occurred is that sewing quality descends.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of rotating shuttle device that is used for Sewing machines, the part of one of them inclination is formed at the first flange place of peg or spindle, to allow bottom line coiling amount significantly to increase, and prevent broken string and kinking, wherein no matter the sewing velocity of sewing material and thickness how, the coupler body of employing has the sewing quality of single form to obtain.

The specific embodiment
The present invention will further be described by embodiment.Obviously it will be understood by those skilled in the art that these embodiment are that more specific description and scope of the present invention are limited by claims and be not implemented example and limit.
Figure 18 is the decomposition diagram that is used for the rotating shuttle device of Sewing machines according to the embodiment of the invention, and Figure 19 is the cross-sectional view of Figure 18.The rotating shuttle device that is used for Sewing machines 1 according to the embodiment of the invention comprises that one is arranged on the coupler body 25 on the driving shaft 10; One bobbin case BC, this bobbin case BC be provided with one that have a mast (studrod) 31 and be contained in bobbin case base 30 and a bobbin case main body 50 that peg or spindle is remained on the outside in the coupler body 20; And a peg or spindle 400, this peg or spindle 400 is formed with second flange that first flange and that an end that is formed on wireline reel by the wireline reel that is arranged on coiling bottom line among the bobbin case BC, contacts with the bottom surface with bobbin case base 30 is formed on the other end of wireline reel.The part of first flange 430 tilts so that form a sloping portion 431 towards winding part.
In the example of expansion peg or spindle 401, preferably, to separate flange 470 and have sloping portion 471, it is towards first flange 430 on its excircle tilt (with reference to Figure 18 and 19).
The mode of operation that is used for the rotating shuttle device of Sewing machines according to the present invention will be described with reference to Figure 22.
According to the present invention, because first flange 430 of peg or spindle 400 is formed with planar base surface 433 and formed sloping portion 431 with the side friction of bobbin case base 30, this sloping portion 431 tilts towards the winding part on its excircle, even the bottom surface 37 of bobbin case base 30 be projection increasing its inner space, the excircle of first flange 430 exposes by the perforate part 38 of bobbin case base 30.Therefore, although a large amount of bottom lines is winding on the peg or spindle 400, thereby apply the tension force of yarn, but between the vertical surface 35 of the far-end of first flange 430 and bobbin case base 30, do not form a gap, the coil of upper thread is not captured during sewing operation thus, and the coil of upper thread can get over sloping portion 431 and break away from easily when keeping the tension force of upper thread 3.
As mentioned above, the coil of upper thread can get over sloping portion 431 and break away from easily when keeping the tension force of upper thread, and then obtains following beneficial effect:
The first, the first flange 430 is because outside tiltedly part 431-was projected into, in other words, the flat bottoms 433 of first flange 430 was expanded, and the length of wireline reel 410 is extended along with the expansion of flat bottoms 433, thereby has significantly increased the coiling amount of peg or spindle.
In peg or spindle, further extend 1mm if be used for the length of wireline reel, the coiling amount of yarn improves 15-20%.Therefore, if first flange 430 is projected into the outside, flat bottoms 433 is expanded therefrom, and the coiling amount can be increased significantly.
The second, because the formation of sloping portion 431, flat bottoms 433 descends with the surface area of bottom surface 37 frictions of bobbin case base 30, and frictional resistance reduces, and bottom line is discharged comparably thus.Because the end of first flange 430 is not exposed to the outside of bobbin case base 30, prevents that like this bottom line from moving to the outside of first flange 430, even when peg or spindle rotates, can prevent broken string or kinking yet.
The 3rd, because the coil of upper thread can move past sloping portion 431 smoothly and leave from the bobbin case base easily, can prevent broken string like this.Say further,, can prolong the length of peg or spindle wireline reel 410 like this, thereby also increase the coiling amount of bottom line owing to bobbin case base 50 is projected into the inner space that the outside increases peg or spindle.
On the other hand, bobbin case main body 50 also can protrude through the outside so that increase the inner space.Further, because outstanding part 55 functions of bobbin case main body 50 are to keep the tension force of upper thread to leave up to the coil of upper thread, the existing hook 25a that is used to grip upper thread no longer needs.Therefore, no matter sewing sewing velocity of material and thickness are how, pinch wheels 25 generally can both be used as single-mode (with reference to Figure 22).
Therefore, owing to there is no need to prepare to have the coupler body of the multiple class of pinch wheels, wherein said pinch wheels has multiple shape according to the sewing velocity and the thickness of sewing material, and the equipment of operation Sewing machines just has been simplified.In addition, because tension force is accurately kept, sewing operation can be finished exactly, so that upper thread 3 and bottom line 4 are set at the mid portion (with reference to Figure 13 and 14) of sewing material, and then obtains good sewing quality.
Simultaneously,, be stretched over the outside, also can make the danger of suture needle 2 collisions drop to minimum, thereby improve security even separate the tension force of flange 470 by the coiling yarn because the part 471 that tilts also is formed on the far-end of separating flange 470.
When the present invention is described in detail, should be appreciated that the multiple variation here, replace and select not break away from the spirit and scope of the present invention that appended claims limits.
