Background technology
For example, form the buttonholing machine of radial stitching in the end in this button of round-nose button hole lock seaming seam hole, have: needle bar reciprocating mechanism, it carries out the pin swing with the amplitude of oscillation of regulation on one side, Yi Bian needle bar is moved up and down; Slew gear, it makes needle bar and the revolution of looper device base of carrying out the pin swing; And the cloth feed mechanism, it makes cloth mobile arbitrarily along horizontal plane (X-Y plane).
For example in patent documentation 1, record on one side and carry out the needle bar actuating mechanism that the pin swing moves up and down needle bar on one side with the amplitude of oscillation of regulation.
In addition, for example record looping mechanism at patent documentation 2, the looper device base that it has pairing left and right looper device and disposes wire grip.
In addition, for example record slew gear in patent documentation 3, it makes described needle bar and the revolution of looper device base of carrying out the pin swing.

In addition, for example in patent documentation 5, record control module, it generates the tailoring pattern data of the described tailoring pattern of being set by described pattern selected cell, based on the tailoring pattern data of this generation described needle bar actuating mechanism, described slew gear and described cloth feed mechanism is controlled.
The situation that to carry out round-nose button hole lock seaming seam shown in Figure 13 describes as an example.Round-nose button hole lock seaming seam is to make through right parallel portion L1, round end hole right lower quadrant L2, round end hole top L3, round end hole lower left quarter L4, each position of left parallel portion L5.
At right parallel portion L1 place, while carry out pin swing from interior pin (near the needle downing position in button hole: the stain the figure) outwards pin (from the button hole away from needle downing position: the white point the figure) carry out the timing that pin is swung, utilize the cloth feed mechanism to carry out the cloth feeding towards the Y direction rear with prescribed distance, thereby form stitching.
At round end hole right lower quadrant L2 place, on the basis of the action identical with right parallel portion L1, by in the timing of carrying out the pin swing from the outside pin of interior pin, utilize the cloth feed mechanism also to carry out the cloth feeding to the X-direction inboard, thereby form inclination stitching toward the outer side.
At L3 place, top, round end hole, while carrying out the pin swing in the timing of carrying out the pin swing from the outside pin of interior pin, utilize the cloth feed mechanism to X-direction and Y direction with circular-arc and carry out the cloth feeding with prescribed distance, and utilize slew gear that needle bar and looper device base are formed on the direction at stitching and turn round with predetermined angular unit, thereby form circular-arc radial stitching.
At round end hole lower left quarter L4 place, while carrying out the pin swing in the timing of carrying out the pin swing from the outside pin of interior pin, utilize the cloth feed mechanism along Y direction with prescribed distance with cloth to the feeding of cloth feeding side, and also carry out the cloth feeding to the X-direction outside, thereby form the inclination stitching towards the inboard.
At left parallel portion L5 place, while carry out pin swing in the timing of carrying out the pin swing from the outside pin of interior pin, utilize the cloth feed mechanism towards Y direction the place ahead with prescribed distance feeding cloth, thereby the formation stitching.
Thus, under the situation that stitching is formed obliquely or forms pivotally, compare with the stitching under the situation of utilizing pin swing straight ahead, the consumption of reaching the standard grade can produce difference.
The curve map of the consumption of reaching the standard grade in each position L1 to L5 of the above-mentioned round-nose button hole lock seaming of expression seam is among Figure 14, be made as at the consumption with parallel portion L1, L5 under the situation of standard consumption, consumption increases in the right lower quadrant L2 of round end hole, in the top L3 of round end hole, reduce slightly, in the lower left quarter L4 of round end hole, further reduce.
That is, at round end hole right lower quadrant L2 place, owing to utilize the cloth feed mechanism to the opposition side feeding cloth of pin swaying direction, therefore the distance from interior pin needle downing position to outer pin needle downing position lengthens, its result, the consumption of reaching the standard grade increase.
In addition, at L3 place, top, round end hole, because with radial formation stitching, therefore the pin needle downing position becomes close with the interval of interior pin needle downing position in, its result, from interior pin needle downing position extremely outside the pin needle downing position distance and the pin amplitude of oscillation about equally, its result, the consumption of reaching the standard grade reduces.
In addition, at round end hole lower left quarter L4 place, owing to utilize the cloth feed mechanism to the direction feeding cloth identical with the pin swaying direction, therefore the distance from interior pin needle downing position to outer pin needle downing position shortens, its result, the consumption of reaching the standard grade minimizing.
Thus, under the situation that stitching is formed obliquely or forms pivotally, compare with the stitching under the situation of pin swing and straight ahead, the consumption of reaching the standard grade produces difference respectively.And, the X that the difference of the consumption of respectively reaching the standard grade can be when tilting, the cloth amount of movement of Y direction or angle of revolution unit and change.The variation of consumption is bigger if reach the standard grade, then can occur reaching the standard grade with the tightness of poor stitching quality such as the bouncing pilotage of not tiing a knot of rolling off the production line or line inhomogeneous make inequality, and the situation of the aesthetic property variation that cloth is wrinkling etc. after making.
For the variable quantity of the consumption that suppresses to reach the standard grade to prevent above-mentioned situation, when making round end hole right lower quadrant L2 or round end hole lower left quarter L4, carry out the amplitude of oscillation that the amount of feeding of the directions X of cloth is proofreaied and correct is proofreaied and correct.
For example, illustration situation that round end hole right lower quadrant L2 shown in Figure 15 is made and describing.Under the situation of not carrying out amplitude of oscillation correction, when suture needle is swung from position P1 to position P2, utilize the cloth feed mechanism with cloth to Y-direction feeding amount of feeding Y1, and, with the opposition side feeding amount of feeding X1 of cloth to the pin swaying direction, so amount of feeding X1 is added among the pin amplitude of oscillation H.And, when suture needle is swung from position P2 to position P3, the cloth invariant position, suture needle is swung.Repeating this action all makes until round end hole right lower quadrant L2 and finishes.
Relative therewith, proofread and correct if implement the amplitude of oscillation, then when suture needle was swung to the right, with cloth opposition side to the suture needle swaying direction on directions X, feeding deducted the amount (X1-a) of corrected value a from amount of feeding X1.On the other hand, when suture needle is swung left, with cloth opposition side feeding corrected value a to the pin swaying direction on directions X.Thus, at round end hole right lower quadrant L2, with the consumption inhibition corrected value a that reaches the standard grade of each pin.

(the processing of control module: the generation of tailoring pattern data)
If carry out the setting input of the setup parameter of Fig. 4, CPU 71 tailoring pattern data that to generate an example of the data content of (calculating) tailoring pattern data shown in Figure 7 be the list form then.
In Fig. 7, " pin falls " is illustrated in each the interior pin under the situation of carrying out a round-nose button hole lock seaming seam, the pin that falls of outer pin, and the pin number is that interior pin, 2 pins that fall of outer pin are counted 1 pin.
" position " represents each position such as the left parallel portion in the affiliated round-nose button hole lock seaming seam of each pin number, right parallel portion, arc sections, round end hole right lower quadrant, round end hole lower left quarter.
" feeding platform XY coordinate " represents the target location of each pin on the X-Y of feeding platform 51 coordinate system.The position, whereabouts of the cloth cutting knife of feeding platform 51 is initial point and apart from the needle bar position of initial point, pre-determines to be set value.Each pin that falls " feeding platform X coordinate " calculates at each position according to setup parameter.For example, at parallel portion 105,106 places, feeding platform 51 is not mobile in X-direction.At round end hole right lower quadrant 102 and round end hole lower left quarter 103 places, according to " feeding platform Y coordinate " described later, calculate in the mode of the shape that becomes rake or arc sections.In addition, the mode of describing arc track with interior pin in arc sections 101 is calculated.
In addition, each pin that falls " feeding platform Y coordinate " calculates according to setup parameter at each position.For example, at right parallel portion 105 and round end hole right lower quadrant 102, left parallel portion 106 and round end hole lower left quarter 103 places, according to " making length " from setup parameter and deduct the part of arc sections 101 and calculating divided by the value that " parallel portion pin number " obtains, at arc sections 101 places, describe the mode of arc track according to interior pin and calculate.
" rotary position " represents the anglec of rotation of the slewing motor 24 of each pin.The angle of revolution of arc sections 101 is that 180 ° are calculated divided by setup parameter " round end vent needle number ".
" needle downing position " is to calculate according to the location variation sum that " feeding platform XY coordinate " and pin are swung the suture needle that causes.
The Δ X of " fall needle gage from " is the variable quantity with the needle downing position X of the last pin that falls, and Δ Y is the variable quantity with the needle downing position Y of the last pin that falls.In addition, L be with the X of the last pin that falls, the synthetic variable quantity that obtains of variable quantity of Y direction.This L represents the distance between the needle downing position of interior pin-outer pin.
" interior pin → outer pin variation delta L " expression is the variable quantity under the situation of benchmark with the distance L between parallel portion 105,106 needle downing position.That is, therefore parallel portion 105,106 Δ L all are 0 owing to be benchmark, about the Δ L at other positions, then calculate by (needle gage that falls at each position is from L)-(needle gage that falls of parallel portion is from L).
" feeding platform XY amount of movement " is the number of drive pulses of the corresponding X-axis motor 52 of each pin, Y-axis motor 53, calculates according to the difference with the value last pin that falls " feeding platform XY coordinate ".
" revolution amount of movement " is the number of drive pulses at the slewing motor 24 of each pin, calculates according to the difference with the value last pin that falls " rotary position ".
For example, the resolution setting of each pulse of X-axis motor 52 and Y-axis motor 53 is 0.1[mm], the resolution setting of each pulse of slewing motor 24 is 1[°].
The tailoring pattern data that generate by above-mentioned processing are stored in the EEPROM 74.
In addition, the CPU 71 that generates the tailoring pattern data by above-mentioned processing works as data generating unit.
If generate above-mentioned tailoring pattern data, then the tailoring pattern data of round end hole right lower quadrant 102 and round end hole lower left quarter 103 are implemented the correction of regulation.For example, CPU 71 is when generating the tailoring pattern data of round end hole right lower quadrant 102 and round end hole lower left quarter 103, the amount of feeding at the directions X of round end hole right lower quadrant 102 and round end hole lower left quarter 103 is the part of a reference value (the 1st a reference value), to the corrected value of this directions X amount of feeding application specifies.On the other hand, not the part of a reference value (the 1st a reference value) at the amount of feeding of the directions X of round end hole right lower quadrant 102 and round end hole lower left quarter 103, the corrected value that CPU 71 will be corresponding with the ratio of this directions X amount of feeding and a reference value is applied to the amount of feeding of directions X.
Below, the flow chart based on the Fig. 8 that is carried out by CPU 71 specifies the order for the data creation method that generates corrected value.
At first, in step S1, judge whether lower-left, the round end hole pin amplitude of oscillation in any setup parameter that inputs to guidance panel 75 is identical with the pin amplitude of oscillation ww of the whole benchmark of seam of lockstitching a border as round-nose button hole, under identical situation, do not need to proofread and correct at round end hole right lower quadrant 102, change step S8 over to, under different situations, round end hole right lower quadrant 102 needs to proofread and correct, and changes step S2 over to.
In step S2, the value that will form the absolute value maximum in the amount of feeding of directions X of each pin number of round end hole right lower quadrant (rake) 102 is set as the 1st a reference value (a reference value).As shown in Figure 9, at round end hole right lower quadrant 102, though the amount of feeding Y1 to Y4 of Y-direction is identical value, the amount of feeding of directions X is that the initial amount of feeding X1 that handles the needle and the last amount of feeding X4 that handles the needle are littler than other amount of feeding X2, X3 that handle the needle.In this step S2, with form the absolute value maximum among the directions X amount of feeding X1 to X4 that respectively handles the needle of round end hole right lower quadrant 102 value, be that amount of feeding X2, X3 set as the 1st a reference value.
In step S3, variable N is set to 0.
In step S4, variable N adds 1 value that obtains becomes new variable N.
In step S5, count the 1st corrected value of N as the pin in each the pin number that forms round end hole right lower quadrant 102, set the directions X amount of feeding of counting N with pin on duty that deducts that amplitude of oscillation ww obtains from round end hole right lower quadrant amplitude of oscillation wx after, the value that obtains divided by the 1st a reference value.Wherein, if counting the amount of feeding of the directions X of N, pin is the value identical with the 1st a reference value, is above-mentioned maximum that then the 1st corrected value is to deduct the amplitude of oscillation and the value that obtains from the round end hole right lower quadrant amplitude of oscillation.On the other hand, count at pin under the amount of feeding of directions X of the N situation different with the 1st a reference value, the ratio of this directions X amount of feeding and the 1st a reference value and deducts from the round end hole right lower quadrant amplitude of oscillation that value that the amplitude of oscillation obtains multiplies each other and the value that obtains becomes the 1st corrected value.
That is, are parts of a reference value (the 1st a reference value) at the amount of feeding of the directions X of rake 102, for the amount of feeding of this directions X, as the corrected value (the 1st corrected value) of regulation, use " (round end hole right lower quadrant amplitude of oscillation wx-amplitude of oscillation ww) * 1 ".
In addition, the amount of feeding for the directions X of rake 102 is not the part of a reference value (the 1st a reference value), for this directions X amount of feeding, corrected value (the 1st corrected value) as regulation is used " (round end hole right lower quadrant amplitude of oscillation wx-amplitude of oscillation ww) * (absolute value of the amount of feeding of directions X)/(a reference value) ", uses the corrected value corresponding with the ratio of this directions X amount of feeding and described a reference value.
In step S6, will add the numerical value that the 1st corrected value obtained by step S5 obtains at the amount of feeding that pin is counted the directions X of N, set the amount of feeding of counting the directions X of N as new pin.
In step S7, judge whether pin is counted N is the total needle amount that forms round end hole right lower quadrant 102, changes step S4 under the situation that is not total needle amount over to, changes step S8 under the situation that is total needle amount over to.
In step S8, judge whether lower-left, the round end hole pin amplitude of oscillation in the setup parameter that inputs to guidance panel 75 is identical with pin amplitude of oscillation ww, under identical situation, do not need to proofread and correct at round end hole lower left quarter 103, finish to proofread and correct and handle, under different situations, round end hole lower left quarter 103 needs to proofread and correct, and changes step S9 over to.
In step S9, the value that forms the absolute value maximum in the amount of feeding of directions X of each pin number of round end hole lower left quarter 103 is set as the 2nd a reference value (a reference value).
In step S10, variable M is set to 0.
In step S11, variable M is added 1 value that obtains be made as new variable M.
In step S12, count the 2nd corrected value of M as the pin in each the pin number that forms round end hole lower left quarter 103, set the amount of feeding of the directions X of counting M with pin on duty that deducts that the amplitude of oscillation obtains from the round end hole lower left quarter amplitude of oscillation after, the value that obtains divided by the 2nd a reference value.Wherein, if counting the amount of feeding of the directions X of M, pin is the value identical with the 2nd a reference value, is above-mentioned maximum that then the 2nd corrected value is to deduct the amplitude of oscillation and the value that obtains from the round end hole lower left quarter amplitude of oscillation.On the other hand, count at pin under the amount of feeding of directions X of the M situation different with the 2nd a reference value, the ratio of the amount of feeding of this directions X and the 2nd a reference value and deducts from the round end hole lower left quarter amplitude of oscillation that the amplitude of oscillation value of obtaining multiplies each other and the value that obtains becomes the 2nd corrected value.
That is, are parts of a reference value (the 2nd a reference value) at the amount of feeding of the directions X of rake 102, for the amount of feeding of this directions X, as the corrected value (the 2nd corrected value) of regulation, use " (the round end hole lower left quarter amplitude of oscillation-amplitude of oscillation ww) * 1 ".
In addition, the amount of feeding at the directions X of rake 102 is not the part of a reference value (the 2nd a reference value), the amount of feeding for this directions X, use " (round end hole lower left quarter amplitude of oscillation x-amplitude of oscillation ww) * (absolute value of the amount of feeding of directions X)/(a reference value) ", that is, use the corrected value corresponding with the ratio of the amount of feeding of this directions X and described a reference value.
In step S13, will in counting the amount of feeding of directions X of M, pin add the value that the 2nd corrected value obtained obtains in step S12, set the amount of feeding of counting the directions X of M as new pin.
In step S14, judge whether pin is counted M is the total needle amount that forms round end hole lower left quarter 103.Under the situation that is not total needle amount, change step S11 over to, under the situation that is total needle amount, finish to proofread and correct and handle.
