Compress member (compress pin) 11 is made detailed description.Fig. 3 is the stereogram of expression compress member 11.Compress member 11 comprises the compress body (infrastructure body) 22 that the basic bar member (superstructure body) 21 that is fixed in presser feet holder 10 is connected with lower end with basic bar member 21.Base bar member 21 forms extend up and down elongated lamellar, and the end is formed with by inserting the fixed part 21a that logical through hole constitutes for screw thereon, is used for this base bar member 21 is fixed on presser feet holder 10.Fixed part 21a forms the elongated long hole shape of extending up and down.Thus, but the fixed position of up-down adjustment compress member 11 relative presser feet holders 10.On the abutting part 11a that is located at the pars intermedia of basic bar member about in the of 21, be formed with by insert the slotting logical 11b of portion that logical through hole constitutes for shank 5 again.Be formed with the pin 24 of overshooting shape near the bottom of basic bar member 21, the downside of pin 24 is provided with the not shown screw that is used for fixing screw 23.
Compress body 22 forms elongated lamellar that above-below direction extends, and the upper end is formed with the connecting hole 25 that is made of through hole.The width dimensions of connecting hole 25 according to the pin 24 chimeric one-tenth of basic bar member 21 roughly closely state set.Again, the downside at connecting hole 25 is formed with the band shoulder hole 26 that the head of screw 23 can be embedded.Connecting hole 25 and band shoulder hole 26 form the long long hole shape of above-below direction.Thus, but the fixed position of using screw 23 up-down adjustment compress bodies 22 basic relatively bar members 21.
On the other hand, the bottom of compress body 22 bends to the approximate right angle shape, forms the horizontal plane shape.For the compress member 11 of present embodiment, at the lower surface of this compress body (infrastructure body) 22 bottoms wired sheet 28 of dodging is installed, shape and structure that this line is dodged sheet 28 have feature.The upper end that line is dodged sheet 28 is embedded into and is installed in (with reference to Fig. 4) in the through hole of being located at compress body 22 bottoms.As Fig. 3～shown in Figure 6, line is dodged sheet 28 is had the pinprick 27 (with reference to Fig. 6 (b)) of the oval shape of using for suture needle 7 break-through by central authorities general cylindrical shape shape formation, be formed with at the lower surface of positive central authorities (along the place ahead central authorities of pinprick 27 major diameter directions) and protrude the roughly preceding push projection of V word shape (first push projection) 29 downwards, at lower surface, be formed with the outstanding downwards back push projection (second push projection) 31 of height identical with preceding push projection 29 along the rear central authorities (opposite side of preceding push projection 29) of identical major diameter direction.Before utilizing push projection 29 and back push projection 31 with sewn object A by being pressed on the needle plate 3.Online cylinder bottom of dodging sheet 28, before the both sides of push projection 29 be formed with symmetrical pair of angled face (line is kept out of the way portion) 30, this pair of angled face (line is kept out of the way portion) 30 is along with from this preceding push projection 29 side and the rear is left and tilt upward gradually to the left and right.That is, preceding push projection 29 is not only to push and is used projection, and is the top on each inclined plane 30.This inclined plane (line is kept out of the way portion) 30 plays line and dodges effect.Also say so, this inclined plane 30 has been configured to following form: when the through wires hole 7a from suture needle 7 extradite the motion of following this sewn object A to the upper thread T of sewn object A move during during with preceding push projection 29 (being the top on inclined plane 30) butt, by this upper thread T is moved along this inclined plane 30, thereby make this upper thread T keep out of the way not needle point position contacting with this suture needle 7.
Line is dodged the configuration of the preceding push projection (first push projection) 29 on the sheet 28 and is considered that preferably the configuration of the through wires hole 7a of suture needle 7 decides.So-called upper thread T just in time contacts (might damage upper thread T thus) and is meant that sewn object moves to (also comprising situation about tilting slightly) occasion of entrance side from the outlet side of through wires hole 7a along the axle center of the through wires hole 7a of suture needle 7 with the needle point of suture needle 7.That is, the sort of occasion, the upper thread T that exposes because of the outlet side from through wires hole 7a moves to entrance side, and the damage possibility takes place so can contact with the needle point of suture needle 7.Therefore, determine inclined plane 30, dodge so that upper thread T dodges the inclined plane 30 of sheet 28 along the line at the sort of occasion.For this reason, in this first example, line is dodged the through wires hole 7a entrance side position that preceding push projection (first push projection) 29 on the sheet 28 is arranged to be in suture needle 7, inclined plane 30 is set in its both sides.Thus, the upper thread T desire of exposing when the outlet side from through wires hole 7a will can be dodged on some inclined planes 30 along the left and right sides at the position of preceding push projection (first push projection) 29 when entrance side moves.In addition, for the ease of threading, normally suture needle 7 is fixed into the form of the inlet of through wires hole 7a, is in side in front of the Sewing machines so be configured to be positioned at preceding push projection (first push projection) 29 its positions of the through wires hole 7a entrance side of suture needle 7 towards the Sewing machines front.
Making of head of sewing machine H to said structure made an explanation.At first, by being moved relative to casing 1 slidingtype, shank box 2 selects shank 5 arbitrarily.Thus, the engagement pin 8a of the shank holder 8 corresponding with selecteed shank 5 engages with the engaging recessed part 9a of shank drive member 9, and the thread take-up tension lever 19 corresponding to this shank 5 engages with take-up drive rod 20 simultaneously.Under this state, in case machine spindle 4 revolution, selecteed shank 5 just pumps, and corresponding with this shank 5 simultaneously thread take-up tension lever 19 also swings up and down.
At this moment, when shank 5 begins when top dead-centre descends, compress member 11 also begins to descend with shank 5.Again, supporting member 14 begins to descend when shank 5 begins to descend.For this reason, set the decrease speed of supporting member 14 for be somewhat slower than shank 5 decrease speed.Thus, engagement pin 10a pulls up to supporting member 14 and is supported member 14 at a certain time point and stops.Thereafter, engagement pin 10a is being supported under the state of supporting member 14, compress member 11 descends until arriving bottom dead centre with the decrease speed of supporting member 14.During this period, because of the decrease speed of the decrease speed specific pressure cloth component 11 of shank 5 fast, so shank holder 8 to presser feet holder 10 near and make helical spring 12 become compressive state.When compress member 11 was in bottom dead centre, the preceding push projection 29 and the back push projection 31 that utilize the line of being located at its lower end to dodge sheet 28 had formed sewn object A by the state that is pressed on the needle plate 3.
When compress member 11 arrives after bottom dead center, helical spring 12 is compressed with the decline of shank holder 8, and shank 5 is proceeded to descend simultaneously.Thus, suture needle 7 is thrust among the sewn object A, and arrival after bottom dead center is transformed into rising and pulls out pin.During this period, compress member 11 stays in bottom dead centre.Shank 5 pulls out pin from sewn object A after, compress member 11 begins to rise from bottom dead centre with supporting member 14, and pin folder 6 clips packing ring 13 ground and abutting part 11a butt at a certain time point.Thereafter, utilize pin folder 6 that abutting part 11a is pushed to, compress member 11 rises with shank 5, and suture needle 7 and compress member 11 revert to state shown in Figure 2.
Make an explanation to dodge the keeping out of the way of upper thread T that sheet 28 carries out by line below.Fig. 4 to Fig. 6 is the figure that the structure that is used to illustrate compress member 11 illustrates the action of suture needle 7 and compress member 11 simultaneously.Fig. 4 is the side view (partial sectional view) of suture needle 7 and compress member 11, Fig. 5 (a) is the side view (partial sectional view) of the needle point of the lower end of compress member 11 and suture needle 7, Fig. 5 (b) is its front view, Fig. 6 (a) is the front view of the needle point of the lower end of compress member 11 and suture needle 7, and Fig. 5 (b) is its vertical view.As shown in Figure 4, after having carried out the making of a certain stitching, sewn object A followed the front side (left side among the figure) of making moving of framework and moving to Sewing machines for next stitching.Thus, extradite upper thread T to sewn object A shown in double dot dash line T ' from the through wires hole 7a of suture needle 7, with open state quickly towards front and back to inclination.Under this state, upper thread T is in position under the needle point of suture needle 7 sometimes.The tip portion of having represented the suture needle 7 of this occasion among Fig. 5.At this moment, shown in this Fig. 5 (b), upper thread T is in the position relative with preceding push projection 29.Under this state, in case sewn object A continues to the front of Sewing machines side shifting then upper thread T and preceding push projection 29 butts.Thereafter, with preceding push projection 29 butts in a certain to the left and right inclined plane 30 of upper thread T divide a word with a hyphen at the end of a line.As shown in Figure 6, inclined plane, upper thread T one edge 30 risings that travel to inclined plane 30 are dodged to the side of suture needle 7 on one side.Thus, the upper thread T that is arranged under the needle point of suture needle 7 keeps out of the way out from the needle point mobile route of suture needle 7.Like this, can avoid the needle point of suture needle 7 to contact with upper thread T.
In addition, after suture needle 7 was just extracted from sewn object A, compress member 11 was near the position of bottom dead centre.Like this, even when after suture needle 7 is just extracted, making framework beginning sewn object A mobile immediately from sewn object A, extradite preceding push projection 29 butts of dodging sheet 28 to the upper thread T of sewn object A with moving of sewn object A with line from the through wires hole 7a of suture needle 7.Thus, the same with aforesaid occasion, upper thread T travels to a certain inclined plane 30, the left and right sides, by 30 rising and to dodge the side of suture needle 7 along the inclined plane.Like this, even when after suture needle 7 is just extracted, beginning sewn object A mobile immediately from sewn object A, make upper thread T leave the needle point mobile route of suture needle 7 because of utilizing inclined plane 30, so even when suture needle 7 risings, can prevent that also the pin of suture needle 7 from contacting with upper thread T.
What represent among Fig. 6 is the occasion that upper thread T the past push projection 29 travels to the inclined plane 30 on right side, but upper thread T in the past push projection 29 to travel to which inclined plane, the left and right sides 30 be that the various situations such as moving direction of the sewn object A during according to stitching decide, under situation about having, also can divide a word with a hyphen at the end of a line on inclined plane 30 to the left.
Upper thread T as mentioned above, adopts the compress member 11 of Sewing machines, even also can utilize inclined plane 30 to make upper thread T keep out of the way out with the needle point mobile route that is arranged in suture needle 7 that moves of sewn object A from the needle point mobile route of suture needle 7 with present embodiment.Like this, can prevent effectively that the needle point of suture needle 7 from contacting with upper thread T, can not damage upper thread T or broken string.Again, adopt the Sewing machines of present embodiment, only need just can prevent effectively that in that inclined plane 30 (line with inclined plane 30 is installed is dodged sheet 28) is set on the compress member 11 needle point of suture needle 7 from contacting with upper thread T on compress member 11.Thus, can make Sewing machines construct uncomplicatedization, can not cause component count to increase and the cost rising.And, adopt the Sewing machines of present embodiment, owing to utilize the inclined plane 30 of being located at compress member 11, can make upper thread T from the needle point mobile route of suture needle 7, keep out of the way out, so the action of making of Sewing machines can be with the same in the past with making the moving of sewn object A in the action usually.Thereby do not need to make the Sewing machines rotating speed to descend or make shank 1 pin that jumps, do not worry to reduce the embroidery efficient of Sewing machines.
[second embodiment]
Below the embroidery machine that uses the compress pin in the second embodiment of the invention is made an explanation.In addition, in the accompanying drawing and explanation thereof of second embodiment, with the general part mark prosign of first embodiment, the detailed description of omitting this part.Below the item beyond Shuo Ming the item is identical with first embodiment.Fig. 7 represents to have the side view (partial sectional view) of head of sewing machine HH of the embroidery machine of second embodiment.Compare with the head of sewing machine H of first embodiment, the component parts of the head of sewing machine HH of present embodiment and actuating mechanism are different slightly.That is, the compress member 50 with head of sewing machine HH is integrally formed with parts, and this point constitutes different with the compress member 11 that head of sewing machine H is had by basic bar member 21 and 22 two parts of compress body.Again, presser feet holder 10 is not set on head of sewing machine HH, the upper end of compress member 50 directly is installed on the periphery of shank 5.Meanwhile, engagement pin 10a that is located at presser feet holder 10 and the supporting member 14 that supports engagement pin 10a have also been omitted.
The compress pin of second embodiment of the invention is that compress member 50 integral body form the elongated tabular of extending up and down, has the planar 50a of upper side abuts portion and the planar middle abutting part 50b of level that is located at pars intermedia of level that is located at the upper end.On 50a of upper side abuts portion and middle abutting part 50b, be formed with the slotting logical portion (not shown) that constitutes by the through hole that connects for shank 5.Be provided with between shank holder 8 and the 50a of upper side abuts portion compress member 50 applied below the helical spring 12 of power.Compress member 50 is along with the decline of shank holder 8, utilizes the application of force of helical spring 12 and descends with shank 5.Stop its decline on the position of packing ring 51 butts of compress member 50 on the lower surface of the 50a of upper side abuts portion and the lateral frame 2b that is located at shank box 2 bottoms.This position becomes the bottom dead centre of compress member 50.
When compress member 50 arrives after bottom dead center, helical spring 12 is compressed with the decline of shank holder 8, and shank 5 is proceeded to descend simultaneously.Thus, suture needle 7 is thrust among the sewn object A, and arrival after bottom dead center is transformed into rising and pulls out pin.During this period, compress member 50 stays in bottom dead centre.Shank 5 pulls out pin from sewn object A after, pin folder 6 clips packing ring 13 ground and middle abutting part 50b butt.Thereafter, utilize pin folder 6 that middle abutting part 50b is pushed to, compress member 50 rises with shank 5,
The compress member 50 of present embodiment has line that the compress member 11 with first embodiment possessed and dodges sheet 28 difform lines and dodge sheet 52.That is, dodge sheet 52 at the tectosome bottom of compress member 50 hookup wire.Fig. 8 is the enlarged front view of suture needle 7 and compress member 50.The preceding push projection (first push projection) 54 that line is dodged sheet 52 is formed at the position (second place) on (in the face of the place ahead middle position (primary importance) along pinprick 27 major diameter directions) deflection right side from the front.That is, in this second embodiment, the preceding push projection (first push projection) 54 that line is dodged sheet 52 is set at the second place that staggers with primary importance corresponding to the through wires hole 7a entrance side of suture needle 7.And the left side of push projection 54 formed the shape that tilts upward around left direction (clockwise direction) along with the past push projection 54 before push projection 54 continuous inclined planes (line is kept out of the way portion) 53 only were located in the past.That is, inclined plane 53 is arranged to leave inclination form that preceding push projection (first push projection) 54 rises such gradually by primary importance (the place ahead central authorities).The inclined plane (line is kept out of the way portion) of such form is not set on the right side of preceding push projection 54 in addition.Like this, dodge at the line of second embodiment and be formed with an inclined plane (line is kept out of the way portion) 53 on the sheet 52.
Adopt the line of this second embodiment to dodge sheet 52, by preceding push projection 54 being formed at the position on the deflection right side of seeing from the front, when upper thread T is arranged in the needle point mobile route of suture needle 7, upper thread T be not at first with preceding push projection 54 (being the top on inclined plane 53) but with the way on inclined plane 53 in butt, then, this upper thread T 53 keeps out of the way the left side of suture needle 7 (because of tension force increases with moving of sewn object A along the inclined plane, so up along the inclined plane with the form that discharges upper thread T tension force), from the needle point mobile route of suture needle 7, break away from.Thus, in the present embodiment, when rising or descend, suture needle 7 can prevent that also the needle point of suture needle 7 from contacting with upper thread T.
Above embodiments of the invention are described, but the present invention is not limited to the foregoing description.Can variously be out of shape in the technical thought range of in the scope of patent application and specification and accompanying drawing, putting down in writing.For example, in above-mentioned first embodiment, expression be to be the example that basic bar member 21 and compress body 22 have constituted compress member 11 by mutual two different parts, but also can be the basic bar member 21 and the compress body 22 of compress member 11 is integrally formed by parts.
Again, sheet (line is kept out of the way portion) dodged by line so long as the shape that can make upper thread T keep out of the way out from the needle point mobile route of suture needle 7, then be not limited to the inclined plane of the such rectilinear form in the inclined plane 30,53 shown in the foregoing description, also the inclined plane that constitutes by curve forms such as spherical shape or arc surface shapes.In addition, line is dodged sheet 28,52 if had inclined plane 30,53 as described above and push projection (preceding push projection 29,54), and then the concrete shape of other parts is not limited to the shape shown in the foregoing description.
Again, what represent in the foregoing description is that the line that will have inclined plane 30,53 is dodged the example that sheet 28,52 is installed on compress member 11,50, but it is integrally formed also line can be dodged the tectosome of sheet and compress member.
What represent in the foregoing description is that the present invention is applicable to two kinds of different head of sewing machine H, the example of HH, and the concrete structure that is suitable for head of sewing machine of the present invention is not limited to the foregoing description.Again, what represent in the foregoing description is the example that the present invention is applicable to multi-needle embroidery machine, and the present invention also is applicable to the other types Sewing machines beyond the multi-needle embroidery machine certainly.
