Description
Technical field
The present invention relates to a kind of shuttle and Sewing machines that prevents the first stitch off-line when making beginning.
Background technology
In the past, had a kind of vertical shuttle that forms upper thread ring and this upper thread ring and bottom line are interweaved from the upper thread of the pinprick extension of suture needle that catches on spur.As this vertical shuttle, have two kinds of rotating shuttle and shuttles.Rotating shuttle can rotate at high speed, in sewing machine for covering chain stitch etc., uses morely.Shuttle is capable of using to be arranged on the pin portion of bearing on the driver of shuttle in the driving and to block deviating from of when making suture needle.Because very fast from the upper thread ring off-line of spur, so shuttle can make the line tensioning well.
This shuttle be used on thick cloth, the to tie a knot Sewing machines etc. of seam.The shuttle that disclosed Sewing machines in the fair 10-328461 communique of Japanese Patent Laid is for example arranged.This shuttle comprises: be fixed on big shuttle body on the framework of base plate, from the place ahead be fixed on the ring-type on this big shuttle body big shuttle, be installed in big shuttle (and big shuttle body) inner shuttle and make in this back and forth driver of rotation of shuttle.In middle shuttle, be provided with shuttle sleeve, shuttle sleeve winds bottom line.Be fixed with the shuttle thread guide plate at big shuttle body with above the big shuttle.On this shuttle thread guide plate, be formed with the breach that allows roughly " T " word shape that suture needle passes.Pass breach and after below moving in suture needle, when rising, from the upper thread of the pinprick extension of suture needle collude just changeing on the spur of shuttle.At this moment, utilize shuttle thread guide plate (breach) to make the upper thread ring that is enlarged by spur be separated to the front side and the rear side of middle shuttle.
In this Sewing machines, as stated, suture needle is when extreme lower position has risen a little beginning to make, and upper thread colludes on the spur.Thus, while upper thread ring enlarges the outer side shifting at middle shuttle.Be later than suture needle and when moving on the extreme lower position, it is roughly maximum that upper thread ring expands at thread take-up tension lever, trend towards throwing off from spur.When middle shuttle rotated roughly half cycle towards positive veer, upper thread ring was thrown off from spur.Shuttle reverses from this moment, simultaneously, is accompanied by the rising of thread take-up tension lever, the upper thread ring tensioning.Thus, the bottom line and the upper thread that extend from shuttle sleeve interweave, thereby form stitching.
In this Sewing machines, between the needle plate of base plate and shuttle thread guide plate, be provided with tangent mechanism sometimes.But this tangent mechanism cuts off upper thread and bottom line through the reciprocating motion of moving knife when making EO.In this case, but when moving knife moves ahead, but the upper thread and the bottom line of cloth side are caught by the seizure portion of usefulness moving knife.But moving knife is when retreating and the dead knife upper thread and the bottom line that interactively quickly cut off the cloth side.
In the shuttle of said Sewing machines, in making operation, the upper thread of the upper thread of suture needle side, cloth side and bottom line pass the peristome of big shuttle body and the breach of shuttle thread guide plate.When making EO, between needle plate and shuttle thread guide plate, utilize tangent mechanism side by side to cut off the upper thread and the bottom line of these cloth sides quickly.At this moment, the reaction of the bottom line of the shuttle sleeve side of having cut off when cutting off beated, and plays pendulum.
Especially crooking or bottom line when having very strong retractility at bottom line, can beat in the narrow range in breach in the end of the bottom line that has cut off.Sometimes the end of this bottom line can be wound on the shuttle thread guide plate, or passes the pin hole of needle plate and move to the upside of needle plate.In this case, bottom line is in the very difficult state that interweaves with upper thread ring.Under this state, when next made beginning, existence can't form the problem of stitching on first stitch.
Summary of the invention
The object of the present invention is to provide a kind of can with next make bottom line that when beginning can keep with the form that upper thread ring intersects cutting off, can be when next makes beginning first stitch form the shuttle and the Sewing machines of stitching under can the situation of off-line reliably.
Shuttle of the present invention; Comprise: be installed in the anterior big shuttle of big shuttle body and be located at this big shuttle dismantledly inner and contain the shuttle sleeve of bottom line shuttle; It is characterized in that; Be formed with the bottom line that cuts off with in sewing finishing time the first notch part on the top of said big shuttle, on said big shuttle, be provided with and can supply suture needle to insert logical shuttle thread guide plate to the front side guiding of said big shuttle, and said shuttle thread guide plate be provided with second notch part with the said first notch part opposed position.
Thus, if when sewing finishing, cut off the bottom line from the extension of bottom line shuttle, the bottom line that has then cut off passes first notch part on the top of big shuttle and mobile to the front side (promptly open distolateral) of big shuttle.Thus, the bottom line that has cut off becomes the state that hangs down towards the open end side direction downside of big shuttle.Under this state, to make on first stitch in when beginning at next, upper thread ring and bottom line interweave reliably, thereby, reliably from the first stitch formation stitching with not having off-line.
In addition, the bottom line that has cut off pass big shuttle first notch part and shuttle thread guide plate second notch part and to the open end of big shuttle side shifting, thereby become the state that hangs down towards the open end side direction downside of big shuttle.Thus, as stated, can be reliably from the first stitch formation stitching.
In the present invention; Best said shuttle sleeve comprises outstanding and with the bottom line guiding bight of leading section guiding from the bottom line of said bottom line shuttle to the top, and said first notch part and said second notch part be arranged on said bottom line guiding corresponding position, bight on.Thus, the bottom line that has cut off pass big shuttle first notch part and shuttle thread guide plate second notch part and to the open end of big shuttle side shifting.In this case, identical when shuttle sleeve being installed in the big shuttle, the bottom line that has cut off becomes the state that the open end side direction downside from the leading section in bottom line guiding bight towards big shuttle hangs down.Thus, as stated, can be reliably from the first stitch formation stitching.
In the present invention, said first notch part and said second notch part are preferably the gap width taper narrower than rear side of front side.Thus, the bottom line that has cut off passes behind first notch part and second notch part side shifting forwards easily, thereby can improve bottom line to the side directed effect in the open end of big shuttle.

Carry out detailed explanation in the face of shuttle 7 down.
Shuttle 7 has like Fig. 2～big shuttle body 11 shown in Figure 4.Big shuttle body 11 is cylindrical vessel shape roughly, is fixed on the framework F (with reference to Fig. 1) of base plate 1.Be provided with the fastener 12 of pairing left and right in the front portion of big shuttle body 11.Front portion at big shuttle body 11 is fixed with the roughly big shuttle 13 of ring-type.This big shuttle 13 utilizes fastener 12 can be installed on the big shuttle body 11 in the past with installing and removing.Shuttle 14 in the inside of big shuttle body 11 and big shuttle 13 is equipped with.On middle shuttle 14, shuttle sleeve 15 is installed dismantledly.Should utilize not shown driver back and forth to rotate by middle shuttle 14.Driver utilizes lower shaft 16 (with reference to Fig. 2, Fig. 3 etc.) and moving up and down of suture needle 6 synchronously back and forth to rotate.Shuttle 7 comprises these big shuttle bodies 11, big shuttle 13, middle shuttle 14, shuttle sleeve 15 and driver etc.
Near the junction surface of big shuttle body 11 and big shuttle 13, be formed with the gathering sill 17 of ring-type.Middle shuttle 14 fronts are seen as roughly semicircle shape.On an end of middle shuttle 14, be formed with the spur 14a that catches on from the upper thread 22 of the pinprick extension of suture needle 6.On the whole length of the peripheral part of middle shuttle 14, be formed with the guide part 14b that the cross section is a convex.Middle shuttle 14 can be directed guide part 14b with being free to slide in gathering sill 17.Middle shuttle 14 synchronously back and forth rotates with moving up and down of suture needle 6 through the reciprocal rotation of driver.
The front end of middle shuttle 14 forms open shape in order shuttle sleeve 15 to be installed dismantledly.On middle shuttle 14, be fixed with along the rearward end of the axle 18 of fore-and-aft direction extension.On this axle 18, shuttle sleeve 15 is installed.The bottom line shuttle (not shown) that is wound with bottom line 23 (with reference to Figure 11, Figure 12) is installed on shuttle sleeve 15 dismantledly.Shown in Fig. 4, Figure 11 etc., the upper end of shuttle sleeve 15 be formed with to above outstanding bottom line guiding bight 15a.Bottom line guiding bight 15a guides the bottom line 23 that reaches the outside from the upper end of the periphery wall of shuttle sleeve 15 with leading section (upper end).
Be formed with in the upper end of big shuttle body 11 and be used to the opening portion 19 that supplies suture needle 6 and upper thread to pass.Gathering sill 17 does not have and opening portion 19 corresponding parts.Be provided with shuttle thread guide plate 20 at big shuttle body 11 with above the big shuttle 13.Shuttle thread guide plate 20 utilizes screw 21 to be fixed on the big shuttle body 11 with freely installing and removing.The suture needle that is formed with roughly " T " word shape in the substantial middle portion of this shuttle thread guide plate 20 is passed with breach hole 20a.
As shown in Figure 3, to pass on the edge part with breach hole 20a in suture needle, the part outstanding to needle downing position N constitutes the separated time 20b of portion.The 20b of this separated time portion will open from the cloth lateral side wire 22b branch that machining cloth CL (with reference to Fig. 7) extends at the rear side (with reference to Fig. 6) of needle downing position N.The 20b of separated time portion will open from the thread take-up tension lever lateral side wire 22a branch that said thread take-up tension lever is supplied with in the front side of needle downing position N (with reference to Fig. 6).Thus, catching on spur 14a when upper thread ring 22c (with reference to Fig. 7) being enlarged, utilize shuttle thread guide plate 20 (20b of separated time portion) that upper thread ring 22c is become and separate with rear side in the front side of middle shuttle 14 easily from the upper thread 22 of the pinprick extension of suture needle 6.
Shown in Fig. 2, Fig. 3, Fig. 5 etc., be formed with the upper thread ring pressing part 13a of the central portion that is positioned on the left and right directions on the top of big shuttle 13.Upper thread ring pressing part 13a pushes down said upper thread ring 22c from the place ahead and makes it be formed on spur 14a side.Be formed with and the left side adjacency of upper thread ring pressing part 13a and the first notch part 13b that extends along fore-and-aft direction on the top of big shuttle 13.The first notch part 13b forms the rear portion and is communicated with and unlimited front side with said opening portion 19.This first notch part 13b is the gap width of the front side taper (with reference to Figure 13) narrower than rear side.Thus, the bottom line 23 that has cut off passes behind the first notch part 13b of taper side shifting forwards easily.
The upper end of the bottom line guiding bight 15a of shuttle sleeve 15 is entrenched in the bottom of the first notch part 13b.Thus, can realize the spline of shuttle sleeve 15, it is stable that the mounting position of shuttle sleeve 15 also becomes.
On shuttle thread guide plate 20, with respect to the first notch part 13b from above opposed position be formed with the second notch part 20c that extends along fore-and-aft direction.The second notch part 20c forms rear portion and suture needle and passes that left part with breach hole 20a links to each other and front side opens wide.This second notch part 20c is the same with the first notch part 13b, also is the gap width taper narrower than rear side of front side.Thus, the bottom line 23 that has cut off passes behind the first notch part 13b that is all taper and the second notch part 20c side shifting forwards easily.
But moving knife 25 is provided in the downside of needle plate 9.As shown in Figure 6, be the downside that the center can be supported on needle plate 9 with rotating freely but moving knife 25 utilizes screw 27 with the level with near the position of the portion right-hand member of big shuttle 13.Dead knife 26 is overlooked and is " L " word shape roughly.But dead knife 26 is configured in the positive upside of moving knife 25 with the form corresponding with the roughly left-half of big shuttle 13.Dead knife 26 utilizes hold-down screw 26b to be fixed on the needle plate 9 the scalable installation site.Leading section at this dead knife 26 is formed with blade 26a down.
But the leading section at moving knife 25 is formed with the 25a of acute angle-shaped line combing portion (Japanese: be eight one).Be formed with the line guide portion 25b of the broad warp shape of guiding cloth lateral side wire 22b continuously with this line combing 25a of portion.Be formed with the 25c of seizure portion of the flexing shape that the cloth lateral side wire 22b to line guide portion 25b guiding catches continuously with this line guide portion 25b.But be formed with the blade 25e that is positioned near the circle the line combing 25a of portion at the leading section of moving knife 25.Be formed with the 25d of the portion of keeping out of the way that the bending ground that supplies thread take-up tension lever lateral side wire 22a to retreat caves in continuously with the line combing 25a of portion.
But what Fig. 6 represented is the state of moving knife 25 shuttle eras.At this moment, but should moving knife 25 make blade 25e be positioned at the front side of cloth lateral side wire 22b and bottom line 23.But the position of this moving knife 25 is called position of readiness.But on the right part of moving knife 25, be connected with along the leading section of the rod member 28 of fore-and-aft direction extension.The rearward end of rod member 28 links to each other with said tangent line driving mechanism.If rod member 28 is driven forwards predetermined stroke by the tangent line driving mechanism, but then moving knife 25 deasil just changes (moving ahead) to position shown in Figure 8 from position of readiness.But the position of moving knife 25 at this moment is called the turned position.If rod member 28 by the tangent line driving mechanism to the rear drive predetermined stroke, but then moving knife 25 reverses (retreating) widdershins to position of readiness from the turned position.
With reference to Fig. 6～Figure 12 the effect of said structure is described.
Making at last in the circulation when sewing finishing descends and when its extreme lower position has risen a little, utilizes spur 14a to catch the upper thread ring 22c of cloth lateral side wire 22b in the front side of suture needle 6 in suture needle 6.This upper thread ring 22c is enlarged by spur 14a.At this moment, like Fig. 6, shown in Figure 7, utilize the 20b of separated time portion to separate cloth lateral side wire 22b and separate thread take-up tension lever lateral side wire 22a in the front side of needle downing position N at the rear side of needle downing position N.
If but moving knife 25 deasil moves ahead under the driving of rod member 28, then the 25a of line combing portion clamp-ons between these two upper thread 22a, the 22b from the left side.At this moment, but moving knife 25 is kept out of the way among the 25d of portion thread take-up tension lever lateral side wire 22a, and via line guide portion 25b cloth lateral side wire 22b and bottom line 23 is directed to the 25c of seizure portion side (with reference to Fig. 8, Fig. 9).
But retreat widdershins under the driving of rod member 28 as if moving knife 25, but then moving knife 25 makes them forwards move (with reference to Figure 10, Figure 11) under the state that captures cloth lateral side wire 22b and bottom line 23 with the 25c of seizure portion.At this moment, but the blade 25e of the blade 26a of dead knife 26 and moving knife 25 meet, side by side cut off cloth lateral side wire 22b and bottom line 23.At last, but moving knife 25 get back on the original position of readiness.Like this, but if cut off the bottom line 23 that comes out from the upper end of the bottom line of shuttle sleeve 15 guiding bight 15a through retreating of moving knife 25 quickly, but the bottom line 23 that has then cut off is beated to the cutting direction of moving knife 25.In other words, shown in figure 12, the bottom line 23 that has cut off forwards side (opening of big shuttle 13 is distolateral) is beated.
Consequently, this bottom line that has cut off 23 is forwards jumped out through the second notch part 20c of shuttle thread guide plate 20 and the first notch part 13b on big shuttle 13 tops easily.The bottom line of jumping out 23 becomes the state that hangs down to downside towards the opening distolateral (the place ahead) of big shuttle 13 from the upper end of the bottom line guiding bight 15a of shuttle sleeve 15.State during this state and the shuttle sleeve that contains the bottom line shuttle 15 are installed in the shuttle 14 time is identical.Thus, make on first stitch in when beginning at next, upper thread ring 22c and said bottom line 23 interweave reliably, thereby, reliably from the first stitch formation stitching with not having off-line.
Like this; The bottom line 23 that when the top of big shuttle 13 is formed with sewing finishing, has cut off is to the first side directed notch part 13b of the open end of big shuttle 13; Can supply suture needle 6 to insert logical shuttle thread guide plates 20 at big shuttle body 11 with being provided with above the big shuttle 13, shuttle thread guide plate 20 with the first notch part 13b opposed position on be formed with the second notch part 20c.Thus, the bottom line 23 that when sewing finishing, has cut off pass big shuttle 13 the first notch part 13b and shuttle thread guide plate 20 the second notch part 20c and towards the open end side shifting of big shuttle 13, thereby hang down to downside.Thus, make on first stitch in when beginning at next, upper thread ring 22c and said bottom line 23 interweave reliably, thereby, reliably from the first stitch formation stitching with not having off-line.
The first notch part 13b and the second notch part 20c are the gap width taper narrower than rear side of front side.Thus, the bottom line 23 that has cut off is side shifting forwards behind the first notch part 13b that passes taper and the second notch part 20c easily, thereby can improve bottom line 23 to the side directed effect in the open end of big shuttle 13.
But between shuttle 7 and needle plate 9, be provided with the tangent mechanism 8 that cuts off cloth lateral side wire 22b and bottom line 23 through the reciprocating motion of moving knife 25.But but the bottom line 23 that when sewing finishing, cuts off through retreating of moving knife 25 follows retreating of moving knife 25 to pass the first notch part 13b and the second notch part 20c, thereby move to the front side of big shuttle 13.Thus, adopt the Sewing machines M of said structure, can be reliably from the first stitch formation stitching.
Change form to having changed above-mentioned example partly describes.
Shown in figure 13, on the big shuttle 13 of shuttle 7A, be formed with the first notch part 13b.Be configured in big shuttle body 11 and comprise cutting apart guide plate 20A and cutting apart guide plate 20B of pairing left and right with big shuttle 13 top shuttle thread guide plates.Cutting apart guide plate 20A and cutting apart guide plate 20B is utilizing screw 21 to be fixed on dismantledly on the big shuttle body 11 under the state that is separated from each other.
Thus, second notch part can be saved, and the effect identical can be obtained with above-mentioned example.
