Specific embodiment
Sewing machine is usually using at least two forward line to generate stitching in workpiece（stitch）.Workpiece can be a piece of knits
Object is placed on needle plate, and needle plate, which is located at, to be attached to below the suture needle on shank.Pinprick is worn with upper thread（top thread）.
Threading suture needle by workpiece and passes through needle plate, so that at least pinprick passes through workpiece.When suture needle is from its extreme lower position to superinverse
During row, a circle upper thread is which created.Mechanism below needle plate catches the circle upper thread, and is secured to what is provided by spool
On bottom line, so as to generate stitching.The mechanism of crawl upper thread is usually made of shuttle and spool sub-assembly.Spool, the spool of bottom line,
In shuttle.The shuttle（shuttle）Pass through the motor rotation in sewing machine.The up and down motion of motor and suture needle synchronously turns
Move the shuttle.Shuttle includes shuttle, which has bill.Planar coil around bottom line and is generated purl by bill.Shuttle and
When rotated with the movement of suture needle so that bill crawl with the often circle upper thread for moving upwards generation of suture needle.The rotation of shuttle
Turning must timing（timed）So that bill is in suitable position compared with the movement of suture needle, and otherwise upper thread and bottom line may not
Form suitable stitching.
The timing of system（timing）The commonly referred to as timing of sewing machine（timing）.With suture needle is caused to swing to a left side
In the sewing machine of the horizontal suture needle swing mechanism of side position and location right, when suture needle is in the possible position of each of which, seam
Threading the timing of machine may be undesirable.When sewing machine " absonant ", that is, when sewing machine timing is not optimal, bill may
Optimum position is not on compared with pinprick.This can be happened at when suture needle is in different lateral positions.This may cause matter
Measure stitching, bouncing pilotage and the broken string of difference.In general, when bill is more than the suture needle risen, the lowest part of bill should be placed exactly in pin
The top of eye.In the sewing machine with horizontal suture needle swing mechanism, as one of suture needle in its a variety of possible lateral position
When at position, bill is only existed in compared with pinprick in optimum position.The other factors for being related to the current sewing conditions of sewing machine also may be used
Sewing machine can be caused absonant.
Fig. 1 a-1f describe the sewing sub-assembly 100 of the prior art.In sub-assembly 100 of sewing, suture needle 101 is in centre
In lateral position.In Fig. 1 c and 1d, suture needle 101 is in leftmost side lateral position.In Fig. 1 e and 1f, suture needle is in rightmost side transverse direction position
It puts.In all Fig. 1 a-1f, when moving upwards generation coil by suture needle 101, the bill 102 of shuttle 103 will capture
Planar coil（It is not shown）At the time of sewing machine is described.As illustrated by figs. 1 a-1f, according to horizontal suture needle position, line is captured in bill 102
At the time of circle, bill 102 will be in different upright positions compared with the pinprick 104 of suture needle 101.
In the sewing sub-assembly of the prior art, if timing is such, i.e., when suture needle 101 is in left-most position,
Bill 102 in the suitable position compared with pinprick 104, and when suture needle 101 is in any other lateral position, sew by the prior art
The bill 102 of sub-assembly may become too low or too high compared with pinprick 104.The variable timing system of the prior art is therefore not
It is optimal, and bill is not accurately positioned all horizontal suture needle positions.This may cause ropy stitching, bouncing pilotage and
Broken string.
Each aspect of the present invention and each embodiment provide the improved variable timing system of sewing machine so that can to avoid by
Ropy stitching, bouncing pilotage and broken string caused by the timing of difference.
Disclosed variable timing system may insure that bill is in suitable position compared with pinprick, but regardless of the transverse direction of suture needle
Position, otherwise can also adjust can make sewing machine become absonant sewing condition.According to each side and each embodiment, improve
Variable timing system include with grabbing the shuttle of line bill.Variable timing system further includes the first helical teeth on shuttle
Wheel and the lower axle for being configured to synchronously rotate shuttle with the vertical movement of the shank with sewing machine.The variable timing system is also wrapped
Include the second helical gear that can be engaged in lower axle and with the first helical gear.In first helical gear and the second helical gear
It is at least one optionally to move in the axial direction.
Variable timing system can also include control device, be configured to processing and represent that sewing machine is currently sewed the number of state
According to, and the equipment can respond the data of processing and optionally generate control signal.Variable timing system can also include driving
Actuating unit is configured to receive control signal, and will be axially moved the helical gear for being transferred to and being axially movable.Drive force mechanisms
The helical teeth being axially movable can be moved axially and take turns to a position in multiple selectable positions, to ensure that bill is in
Suitable position, the multiple selectable position provide in the scope for extending to the second end position from the first end position.
According to second aspect, the method for disclosing to be selectively adjusted the timing of the variable timing system of sewing machine.
Variable timing system is included with the shuttle and the first helical gear on shuttle for grabbing money bill.Variable timing system is also
Including lower axle, which is configured to synchronously rotate shuttle with the vertical movement of the shank of sewing machine；With the second helical gear, peace
It can be engaged in lower axle and with the first helical gear.It is at least one optional in first helical gear and the second helical gear
Move in the axial direction to property.This method includes the data for state of currently sewing by control device processing expression sewing machine.
The data that this method further includes in response to processing selectively generate control signal, and in response to control signal, will be axially moved
