The situation carrying out the round-nose button hole lock seaming seam shown in Figure 13 is carried out as an example
Explanation.Round-nose button hole lock seaming seam is through right parallel portion L1, round end hole right lower quadrant L2, circle
Head bore top L3, round end hole lower left quarter L4, each position of left parallel portion L5 and sew.
At right parallel portion L1, carry out pin and swing from interior pin (close button hole
Needle downing position: the stain in figure) outwards pin (from button hole away from needle downing position: figure
White point) carry out the timing of pin swing, utilize cloth feeding mechanism towards Y direction rear
Carry out cloth feeding with prescribed distance, thus form stitching.
At the right lower quadrant L2 of round end hole, on the basis of the action identical with right parallel portion L1,
By carrying out the timing of pin swing from the outside pin of interior pin, utilize cloth feeding mechanism also to X
Carry out cloth feeding inside direction of principal axis, thus form the inclination stitching towards outside.
At the top L3 of round end hole, carry out pin swing and carrying out from the outside pin of interior pin
The timing that pin swings, utilizes cloth feeding mechanism to X-direction and Y direction with arc-shaped
And carry out cloth feeding with prescribed distance, and slew gear is utilized to make needle bar and looper base
Formed at stitching and turn round with predetermined angular unit on direction, thus form the radiation of arc-shaped
Shape stitching.
At the lower left quarter L4 of round end hole, carry out pin and swing entering from the outside pin of interior pin
The hand-manipulating of needle swing timing, utilize cloth feeding mechanism along Y direction with prescribed distance by cloth
Material is to cloth feeding side feeding, and also carries out cloth feeding outside X-direction, thus
Form the inclination stitching towards inner side.
At left parallel portion L5, carry out pin swing and carrying out pin from the outside pin of interior pin
The timing swung, utilizes cloth feeding mechanism towards Y direction front with prescribed distance feeding
Cloth, thus form stitching.
Thus, in the case of stitching is formed obliquely or is formed pivotally, swing with utilizing pin
Stitching in the case of straight ahead is compared, and the consumption reached the standard grade can produce difference.
Notationally state the consumption of reaching the standard grade in each position L1 to L5 of round-nose button hole lock seaming seam
In curve map i.e. Figure 14 of amount, the consumption of parallel portion L1, L5 is being set to standard consumption
In the case of amount, in the right lower quadrant L2 of round end hole, consumption increases, at round end hole top L3
In slightly reduce, reduce further in the lower left quarter L4 of round end hole.
That is, at the right lower quadrant L2 of round end hole, owing to utilizing cloth feeding mechanism to pin swing side
To opposition side feeding cloth, therefore add to the distance of outer pin needle downing position from interior pin needle downing position
Long, its result, the consumption reached the standard grade increases.
It addition, at the top L3 of round end hole, due to radial formation stitching, therefore in pin
The interval of needle downing position and interior pin needle downing position becomes close, its result, from interior pin needle downing position to
The distance of pin needle downing position is roughly equal with the pin amplitude of oscillation, its result, and consumption of reaching the standard grade reduces.
It addition, at the lower left quarter L4 of round end hole, owing to utilizing cloth feeding mechanism to put to pin
The direction feeding cloth that dynamic direction is identical, therefore from interior pin needle downing position to outer pin needle downing position
Distance shortens, its result, and consumption of reaching the standard grade reduces.
Thus, in the case of stitching is formed obliquely or is formed pivotally, swing also with pin
Stitching in the case of straight ahead is compared, and consumption of reaching the standard grade produces difference respectively.Further, respectively
Reach the standard grade consumption difference can along with tilt time X, the cloth amount of movement of Y direction or revolution
Angular unit and change.The changing greatly of consumption if reached the standard grade, then there will be and reach the standard grade and roll off the production line
The uneven sewing of the tightness of the stitching defects such as the bouncing pilotage do not tied a knot or line is uneven and cloth
Expect the situation that the wrinkling aesthetic property waited after sewing is deteriorated.
In order to the variable quantity of the consumption that suppresses to reach the standard grade is to prevent above-mentioned situation, in sewing round end hole
During right lower quadrant L2 or round end hole lower left quarter L4, the amount of feeding carrying out the X-direction to cloth enters
The amplitude of oscillation correction of row correction.
Such as, illustrate situation that the round end hole right lower quadrant L2 shown in Figure 15 is sewed and
Illustrate.In the case of not carrying out amplitude of oscillation correction, in suture needle from position P1 to position P2
During swing, utilize cloth feeding mechanism by cloth to Y-direction feeding amount of feeding Y1, and,
By cloth to the opposition side feeding amount of feeding X1 of pin swaying direction, therefore amount of feeding X1 is added in
In pin amplitude of oscillation H.Further, when suture needle swings to position P3 from position P2, cloth position
Constant, suture needle swings.Repeat this action until round end hole right lower quadrant L2 has all sewed
Become.
On the other hand, if implementing amplitude of oscillation correction, then when suture needle swings to the right, by cloth
In the X direction to the opposition side of suture needle swaying direction, feeding deducts corrected value from amount of feeding X1
The amount (X1-a) of a.On the other hand, when suture needle swings to the left, by cloth in X-direction
On to the opposition side feeding corrected value a of pin swaying direction.Thus, at round end hole right lower quadrant L2,
By the consumption suppression corrected value a that reaches the standard grade of each pin.

The part of quasi-value (the 1st a reference value), CPU 71 will be with this X-direction amount of feeding and a reference value
The corresponding corrected value of ratio, be applied to the amount of feeding of X-direction.
Below, flow chart based on the Fig. 8 performed by CPU 71, illustrate for generating
The order of the data creation method of corrected value.
First, in step sl, it is judged that input any setup parameter to guidance panel 75
In the pin pendulum of lower-left, the round end hole pin amplitude of oscillation and the benchmark overall as round-nose button hole lock seaming seam
Width ww is the most identical, under identical circumstances, need not correction at round end hole right lower quadrant 102,
Proceeding to step S8, in different situations, round end hole right lower quadrant 102 needs correction, proceeds to
Step S2.
In step s 2, each pin number in round end hole right lower quadrant (rake) 102 will be formed
The value of the maximum absolute value in the amount of feeding of X-direction sets as the 1st a reference value (a reference value).
As it is shown in figure 9, at round end hole right lower quadrant 102, although the amount of feeding Y1 to Y4 of Y-direction
It is identical value, but the amount of feeding of X-direction is the initial amount of feeding X1 handled the needle and last

103 need correction, proceed to step S9.
In step s 9, entering of the X-direction of each pin number of round end hole lower left quarter 103 will be formed
The value giving the maximum absolute value in amount sets as the 2nd a reference value (a reference value).
In step slo, variable M is set to 0.
In step s 11, the value adding 1 by variable M and obtaining is set to new variable M.
In step s 12, as the pin number in each pin number forming round end hole lower left quarter 103
2nd corrected value of M, sets and deducts, from the round end hole lower left quarter amplitude of oscillation, the value that the amplitude of oscillation obtains and be multiplied by
After the amount of feeding of the X-direction of pin number M, the value obtained divided by the 2nd a reference value.Wherein,
If the amount of feeding of the X-direction of pin number M be the value identical with the 2nd a reference value, the most above-mentioned
Big value, then the 2nd corrected value is the value deducting the amplitude of oscillation from the round end hole lower left quarter amplitude of oscillation and obtaining.Separately
On the one hand, in the case of the amount of feeding of X-direction of pin number M and the 2nd a reference value are different,
The amount of feeding of this X-direction and the ratio of the 2nd a reference value, deduct with from the round end hole lower left quarter amplitude of oscillation
The amplitude of oscillation obtains being worth the value being multiplied and obtain and becomes the 2nd corrected value.
That is, the amount of feeding in the X-direction of rake 102 is a reference value (the 2nd a reference value)
Part, for the amount of feeding of this X-direction, as the corrected value (the 2nd corrected value) of regulation,
Application " (the round end hole lower left quarter amplitude of oscillation-amplitude of oscillation ww) × 1 ".
It addition, the amount of feeding in the X-direction of rake 102 is not a reference value (the 2nd benchmark
Value) part, for the amount of feeding of this X-direction, apply " (round end hole lower left quarter amplitude of oscillation x
-amplitude of oscillation ww) × (absolute value of the amount of feeding of X-direction)/(a reference value) ", i.e. should
With the corrected value corresponding with the ratio of the amount of feeding of this X-direction and described a reference value.
In step s 13, will add in step in the amount of feeding of the X-direction of pin number M
The value that the 2nd corrected value obtained in S12 obtains, sets the X-direction as new pin number M
The amount of feeding.
In step S14, it is judged that whether pin number M is the total of formation round end hole lower left quarter 103
Pin number.In the case of not being total needle amount, proceed to step S11, tie in the case of being total needle amount
Beam alignment processes.
