(moving cutter mechanism)
Then, with reference to Fig. 3～Fig. 5 moving cutter mechanism 50 is described.
Here, Fig. 3 is that stereogram, Fig. 4 of the cut-out possibility state of cutter mechanism 50 and pin knee-action mechanism 40 are that stereogram, Fig. 5 of the cutter mechanism 50 and the cut-out restriction state of pin knee-action mechanism 40 are the stereograms from the moving cutter mechanism 50 of the direction observation different with Fig. 3 and Fig. 4.
As Fig. 3～shown in Figure 5, moving cutter mechanism 50 has: the central cutter 51 that forms center joint-cutting S; Have central cutter 51 in the bottom and in chain-drive section 12c along the supported slidably cutting knife rod 52 of Z-direction; Be fixed on the sewing machine stand and support the axle sleeve 53 of cutting knife rod 52 along long side direction slidably; Fixed equipment is at the cutting knife rod abut 54 in the long side direction centre position of cutting knife rod 52; Be arranged on the hornblock 55 on the cutting knife rod abut 54; Being fixedly supported on the sewing machine stand 12 and by hornblock 55 makes cutting knife rod 52 not rotate the guide housing 56 that moves of the above-below direction that leads; Cutter motor 57 as the stepper motor of the drive source of central cutter 51 knee-actions; The connected toggle-action lever 59 in eccentric cam 58, one ends that output shaft 57b by relative cutter motor 57 is installed by off-centre; The swing end is connected the input arm 60 of the other end of toggle-action lever 59; One end is connected with input arm 60 and is fixed on that bearing 70 on the sewing machine stand supports and the turning cylinder 61 that rotates; The other end and the turning cylinder 61 integrally formed output arms of swinging 62 at turning cylinder 61; One end is connected the first connecting rod body 63 of the swing end of output arm 62; Connect the other end of first connecting rod body 63 and the second connecting rod body 64 of cutting knife rod abut 54; As the cylinder 65 that possible state of the cut-out of central cutter 51 and cut-out restriction state is carried out the drive source of change action; One end is connected on the push rod of cylinder 65 and carries out the lever part 66 of wobbling action; The binding connecting rod body 67 of the tie point J of connection first connecting rod body 63 and second connecting rod body 64 and the other end of lever part 66; When giving prominence to, cylinder 65 make push rod stop at the stop 68 of assigned position.
Above-mentioned moving cutter mechanism 50, can and cut off between restriction and the state at cut-out possibility state and switch, described switching possibility state, be meant the state that up and down reciprocatingly moves and transmit that when cylinder 65 is positioned at going-back position (state of Fig. 3), the rotary driving force of cutter motor 57 is changed into central cutter 51, described cut-out restriction state is meant that the rotary driving force of cutter motor 57 when cylinder 65 is positioned at progressive position (state of Fig. 4) can not be delivered to the state of central cutter 51.
That is, above-mentioned lever part 66, with its long side direction centre position fulcrum that is swing and at the axis of oscillation of this fulcrum towards being supported on the sewing machine stand 12 under the state of Y direction.And when cylinder 65 was in the state of stepping back, lever part 66 was via linking connecting rod body 67, with the point of contact J of first connecting rod body 63 and second connecting rod body 64 maintain with its oscillation center line that pulls to specific output arm 62 by under the position on.
Drive if under this state, carry out the rotation of above-mentioned cutter motor 57,, can make an end of toggle-action lever 59 carry out circular motion then by being installed in the eccentric cam 58 on the output shaft 57b of Y direction.Toggle-action lever 59 is by the circular motion of one end, and the motion of can advancing and retreat of its other end is swung thereby input arm 60 is produced.Thus, turning cylinder 61 rotates, and makes output arm 62 swings.
The point of contact J of first connecting rod body 63 and second connecting rod body 64 is restricted to and only can carries out being the center, being the state of the circular motion of radius with this binding connecting rod body 67 with the end (with the binding end of lever part 6) that links connecting rod body 67.And, carry out this circular motion by point of contact J, the oscillating motion of output arm 62 can make cutting knife rod 52 and central cutter 51 knee-actions via first connecting rod body 63 and second connecting rod body 64, cuts off action.
On the other hand, when cylinder 65 is in the state that advances, the push rod of this cylinder 65 is limited in the position with stop 68 butts, lever part 66 is via linking connecting rod body 67, and the point of contact J of first connecting rod body 63 and second connecting rod body 64 is pulled on and maintains on the line that becomes the oscillation center of output arm 62 line.
