Shuttle 12 is positioned under supporting plate, and this shuttle has the shuttle body with spur 12a, and this supporting plate does not illustrate in the drawings, and this supporting plate is arranged in the recess 11a of substrate 2.Shuttle 12 is configured to tubular shuttle.For holding the cylindricality supply shell 12 of shuttle thread supply, be arranged on shuttle body.The cylindricality axis of this supply shell 12b is vertical with the pivot center of shuttle 12.This supply shell 12b is configured to hold lower line bobbin.Therefore supply shell 12b is called reel case.
Shuttle 12 can rotate around horizontal shuttle axis 13.
In Fig. 2 in tangent position and in Fig. 3 the tangent line assembly 15 in initial position for both cutting off upper lines 11, cut off again shuttle thread or lower line 14(referring to Fig. 3).When making abundant sewing, these two lines 11,14 have large thickness, this thickness can be for example 1mm and more than.
In arc mode, around pivot axis 18 structure, take out line blade 16, thereby this is taken out line blade 16 and can between initial position and tangent position, be shifted around these pivot axis 18 pivotables.Take out line blade 16 and there is arc carrying body 19, on this carrying body by assembly adjutage 21 screw take out line blade 16 also for arc cutter blade 20.This carrying body 19 is thereby that in the arc initial position assembling, it is arranged to around shuttle 12.
Take out line blade carrying body 19 and be connected to non-rotatingly blade shaft 22, this blade shaft 22 is parallel to arm axle 6 along pivot axis 18 and extends in substrate 2.The pivot axis of taking out line blade carrying body 19 is parallel to shuttle axis 13.Unshowned, be wherein also like this in the vertically extending alternate embodiment of shuttle axis.In the case, the pivot axis of taking out line blade carrying body also vertically extends.In the situation that shuttle axis is vertical, takes out line blade 16 and be arranged to rotate 90 ° with opposition blade 17, thereby in this alternate configuration, take out the interoperable cut edge when line is cut off of line blade 16 and opposition blade 17 and extend substantially vertically.
Take out line blade 16 and have two take- up grooves 25,26 of arranging apart from each other, each take-up groove has cutter, and described cutter is with cut edge 26a separately.Cut edge 26a is the edge transition region between take- up groove 25 and 26 on the one hand, is the upside of taking out line blade 16 on the other hand.At the take-up groove 26 shown in the top of Fig. 3 for provoking upper lines 11, at the take-up groove 25 shown in the bottom of Fig. 3 for provoking lower line 14.These two take- up grooves 25 and 26 are arranged on the both sides of the blade base 27 of taking out line blade 16.
These two take- up grooves 25 and 26 are opening in the same direction, from the free end of taking out line blade 16 in initial position, looks, and this direction is takes out line blade 16 towards the direction of motion of take-up position and tangent position.
The exploded view of Fig. 5 further illustrates the screw 30 with counterbore head, and this screw 30 is for being fixed to opposition blade 17 the top contact-making surface 31 of back-up block 28.For this reason, screw 30 is screwed in the screw thread 32 being configured in contact-making surface 31.Screw 30 and opposition are also furnished with spherical cap 33 between blade 17, and this spherical cap 33 is configured to conical socket 34 in the tapped through hole 35 with the blade 17 that opposes and coordinates.
Between opposition blade 17 and contact-making surface 31, be furnished with for regulating the threaded 36 of this opposition blade 17.Screw-in depth in another screwed hole 37 according to screw 36 in the contact-making surface 31 of back-up block 28, can pre-determine the cut edge 38 of opposition blade 17 with respect to the relative cutting position of taking out the cut edge 26a of line blade 16.
The cutting pressure when radius of the blade base 27 by extending to cut point in take- up groove 25 and 26 regions produces tangent line between cut edge 26a and 38.
Sewing machines 1 is worked as follows: during making normally, take out line blade 16 in initial position.Under the effect of shuttle and pin 10, shuttle thread 14 and needlework 11 in known manner Cheng Huan and knotting to form stitching.When stitching forms EP (end of program), to these two strands, 11,14 starting tangent line operations.For this reason, actuated blade drive unit, this blade drive makes to take out line blade 16 by means of blade driving shaft 24, connecting rod 23 and blade shaft 22 and is pivoted to tangent position from initial position.This takes out 16 motions of line blade through take-up position, and in this take-up position, take-up groove 25 is provoked upper lines 11, and take-up groove 26 is provoked lower line 14.
Because for two take-up grooves 25 of two strands 11,14 and 26 the setting being separated from each other, can prevent that this two strand 11,14 from mutually interfering in take- up groove 25 and 26.
In the situation that groove 25,26 is provoked line 11,14, then opposition blade 17 arrives tangent position, and in this tangent position, line 11,14 is cut off taking out between the cut edge 26a of line blade 16 and the cut edge 38 of opposition blade 17.Then take out line blade 16 and return to initial position by the driving of parts 22 to 24.
To illustrate with other two kinds of configurations of taking out the tangent line assembly of line blade and opposition blade by means of Fig. 7 and Fig. 8 below.With above referring to figs. 1 through the corresponding parts of the parts of the tangent line assembly explanation of Fig. 6, will use identical Reference numeral and will no longer describe in detail.
According in the configuration of Fig. 7, extend obliquely with respect to the connecting line 30 between two cut edge 26a of take- up groove 25,26 cut edge 38 of opposition blade 17.This opposition blade cuts edge 38 in the region of tangent position with the β angle of 39 one-tenth 8 ° of this connecting lines.According in the configuration of Fig. 7, the cut edge 38 of opposition blade 17 meets at right angles with the direction of motion 40 of taking out the tangential motion with respect to opposition blade 17 of line blade 16.Thus, two cut edge 26a by take- up groove 25,26 are relative to each other offset this fact in the direction of motion 40, have produced the inclination stroke of opposition blade cuts edge 38 with respect to the connecting line 39 of two cut edge 26a.This skew can be for example completely in the scope in 1mm to 2mm.
Because above-mentioned inclination stroke, according in the configuration of Fig. 7, first the line of being provoked by take-up groove 25 is cut off, and is then that the line of being provoked by take-up groove 26 is cut off.Therefore shearing force between cut edge 26a and 38 is not to work simultaneously but one after the other work to cut off this two strand.
According in the configuration of the tangent line assembly of Fig. 8, opposition blade cuts edge 38 is not perpendicular to the direction of motion 40 extensions of taking out line blade 16, but with 40 one-tenth minimum angles α of this direction of motion, this angle [alpha] is less than 88 ° and in the configuration illustrating, be about 78 °.The line blade 16 of taking out in the configuration of Fig. 8 is also accurately constructed with respect to the layout of cut edge 26a as taking out line blade 16 of Fig. 6.Therefore according to the taking out in line blade 16 of Fig. 8, cut edge 26a is not arranged in relative to each other skew in the direction of motion 40.
Due to the inclination stroke at opposition blade cuts edge 38, when carrying out when line cuts off producing the continuous shearing force process of correspondence with minimum shearing force, then the line that is just first cut off and is provoked by take-up groove 26 as the line of being provoked by take-up groove 25 is cut off.
