As shown in Figures 1 and 2, Sewing machines 1 has the pedal 8 that works as input switch.According to the operator to pedal 8 enter into action with and the amount of entering into, can make various inputs indications such as the beginning of action/stop.
(stitch data and make action)
Below, stitch data 51 is described and based on the action of making of the Sewing machines 1 of this stitch data 51.Stitch data 51 comprises the information that is used for making the needle downing position of the predefined stitching of formation on the thing.Each needle downing position of stitch data 51 comprises the relevant information of assigned position (point of origin P) distance apart on the X-Y plane with itself and cloth pressing 22 and lower plate 21.Initial needle downing position, comprise with itself and point of origin P in X-direction and the relevant information of Y direction distance apart, the needle downing position that second stitching is later comprises the information relevant with the distance of previous needle downing position on X-direction and Y direction with it.That is, the needle downing position shown in the stitch data 51 is and the corresponding relative position information of needle downing position before.Control part 40 adds up, stores and manage the later needle downing position information of second stitching by beginning from initial needle downing position, can also obtain absolute location information.To the fall pin sequence number that falls of pin order of each needle downing position additional representation.The pin sequence number that falls is that the pin sequence number that falls with initial needle downing position is made as zero and progressive whole number value successively.
CPU 41, by positional information based on each needle downing position of stitch data 51, drive X-axis motor 25 and Y-axis motor 26, cloth pressing 22 and lower plate 21 are moved, thereby make and make thing and move, and the timing that control moves up and down needle bar 11 by the driving of sewing machine electromotor 6, with the corresponding position of each needle downing position of stitch data 51 on the pin that falls, form stitching on the thing making.
Specifically, as shown in Figure 3, CPU 41 at first makes cloth pressing 22 and lower plate 21 move to point of origin P, and cloth pressing 22 and lower plate 21 are moved so that with the corresponding position of initial needle downing position be positioned at pin hole directly over (empty feeding).Then,, then needle bar 11 is descended, carry out and the corresponding pin that falls of initial needle downing position by driving sewing machine electromotor 6 if carry out the action of entering into to pedal 8.And after pulling out pin, before the pin that next time falls, CPU 41 drives X-axis motor 25 and Y-axis motor 26, carries out feed motion in that needle bar 11 is risen, and makes cloth pressing 22 and lower plate 21 move rate of travel based on next needle downing position information.In addition, by the pin that falls once more, form stitching.Then, till the last needle downing position of stitch data 51, carry out same action.
(judgement of site error)
Below, illustrate that needle downing position has or not the judgement of site error.
In making action, with respect to the positional information of each needle downing position shown in the stitch data 51, actual needle downing position may produce error.That is, with respect to the anglec of rotation of corresponding X-axis motor 25 of each needle downing position and Y-axis motor 26, carrying out producing deviation sometimes with this needle downing position corresponding fall X-axis motor 25 during pin and the anglec of rotation of Y-axis motor 26.CPU 41 is based on the testing result of X-axis encoder 28 and Y-axis encoder 29, calculate based on the anglec of rotation of the X-axis motor 25 of the positional information of each needle downing position shown in the stitch data 51 and Y-axis motor 26 and the anglec of rotation of X-axis motor 25 when falling pin and Y-axis motor 26 between deviation (as the function of " error detection unit ").The anglec of rotation separately of 41 pairs of X-axis motor 25 of CPU, Y-axis motor 26 is carried out deviation calculation, under the situation of some at least deviations, judge that the pin that falls that produces this deviation has produced site error (as the function of " identifying unit ") more than or equal to deviation detection threshold D.CPU 41 is at the pin that falls that produces site error, with this needle downing position sequence number when falling pin X-direction and the deviation of Y direction be associated, be recorded among the deviation record buffer memory device 44a.
As shown in Figure 4, at the deviation detection threshold is under the situation of " 10 ", what be recorded in site error among the deviation record buffer memory device 44a falls pin information as shown in Figure 5, is that some at least deviations in the deviation (deviation Y) of deviation (deviation X), Y direction of X-direction are more than or equal to 10.In addition, the numerical value of the unit of deviation detection threshold and deviation X and deviation Y and unit in the present embodiment, are the umber of pulses of each encoder output when detecting the anglec of rotation for arbitrarily.
As mentioned above, have the EEPROM 44 of deviation record buffer memory device 44a, work as " error needle downing position information memory cell ".
The information of each needle downing position obtains, and promptly utilizes the detection of X-axis encoder 28 and Y-axis encoder 29, carries out before being used for the feed motion of next needle downing position.Below, it is elaborated.
CPU 41 monitors the anglec of rotation of the main shaft that spindle encoders 7 are detected, needle bar 11 move up and down the position for the position of regulation (suture needle extract from cloth regulation regularly) time, the feed motion that control is undertaken by travel mechanism 20.
Specifically, if the anglec of rotation of main shaft surpasses the predetermined data output angle, then CPU 41 reads the positional information of next needle downing position.Then, begin angle, then utilize X-axis encoder 28 and Y-axis encoder 29 to detect the X-axis motor 25 of this moment and the anglec of rotation of Y-axis motor 27, carry out feed motion then if the anglec of rotation of main shaft surpasses the feeding of regulation.
In addition, CPU 41 is behind feed motion, before the timing of the positional information of reading next needle downing position, based on the testing result of X-axis motor 28 and Y-axis motor 29, judge that needle downing position has or not site error, under the situation of location error in deviation record buffer memory device 44a record.For example, after the positional information of reading second pin, before the feed motion of the pin that falls that is used for second pin, by obtaining the testing result of X-axis encoder 28 and Y-axis encoder 29, the X-axis motor 25 when obtaining carrying out the initial pin that falls (first pin) and the anglec of rotation of Y-axis motor 27, afterwards from second pin fall pin before the positional information of reading the 3rd pin during, the record when finishing the judgement of site error of first pin and site error.In addition, also can store the X-axis encoder 28 of each needle downing position, the testing result of Y-axis encoder 29, after making action, carry out site error uniformly and judge.
Data output angle and feeding begin angle, are stored in ROM 43 or EEPROM44 some, are read by CPU 41 when making the action beginning.
CPU 41 is for the judgement of site error, is that the two is judged to the relative position error and absolute position error.
In the present embodiment, along with making continuing of action, the deviation of the anglec of rotation of X-axis motor 25, Y-axis motor 26 increases gradually and produces site error, its result, produce as absolute location coordinates under the situation of site error, CPU 41 judges that this needle downing position produces site error.For example, according to the positional information pin that falls, at least one deviation after second pin among deviation X, the deviation Y is each to be increased under 2 the situation, produces site error at the 6th pin at first pin.In this case, because the 6th pin only produces 2 with respect to the 5th pin deviation, thus relative site error do not produced, but by the accumulative total site error, for absolute position, because of the accumulative total of deviation produces site error based on the 6th pin of the positional information of stitch data 51.In this case, CPU 41 judges that the 6th pin produces site error.
On the other hand, suppose to produce site error at first pin.In this case, since feed motion based on relative position information, so after second pin, pin all falls in the position of the site error that comprises first pin.At this moment, if the pin that falls of second pin carries out according to the positional information of the needle downing position of stitch data 51, then the site error that produces because of first pin of second pin produces the site error as the absolute position, but second pin does not produce relative site error with respect to first pin.In this case, CPU 41 judges that first pin produces site error, judges that second pin does not produce site error.That is, CPU 41, for the needle downing position after the needle downing position that produces site error, judge site error based on the relative position error with respect to previous needle downing position.In addition, for not producing site error with respect to the absolute location coordinates that begins accumulative total from initial needle downing position, but produce the needle downing position of relative site error with respect to previous needle downing position, CPU 41 judges it is the needle downing position that produces site error.
In the present embodiment, before judging site error of generation based on absolute location information, judge based on the absolute position, produced in judgement under the situation of absolute position error, whether next needle downing position has been produced the relative position error with respect to the relative position that is determined the needle downing position that has produced the absolute position error judge.
Can at random determine the compound decision condition of the relative position error and absolute position error.For example, can be provided for judging the threshold value (the 1st threshold value) of absolute position error respectively and be used to judge the threshold value (the 2nd threshold value) of the relative position error, under situation more than or equal to some or these two threshold values, judge to produce site error, also can utilize other decision method.Certainly, also can only judge some in the relative position error or the absolute position error.
(demonstration of site error)
Below, the demonstration of the information relevant with the needle downing position that produces site error is described.
Making in the operation of carrying out based on stitch data 51, exist under the situation of the pin that falls that produces site error, control part 40 shows that on the display part 31 of guidance panel 30 expression produces the picture (error image display frame) of the needle downing position of site error.That is, display part 31 works as " display unit ".
As shown in Figure 6, error image display frame, utilize the point on the picture, be presented at the position relation of whole needle downing position of setting in the stitch data 51, and, be presented at and make the needle downing position that produces the needle downing position of site error in the action and do not produce site error wherein with discernible state.In the present embodiment, to be different from the color of other needle downing position, show and the corresponding point of needle downing position that produces site error.In addition, in Fig. 6, produce the needle downing position of site error with circle (inner blank point) expression, do not produce the needle downing position of site error with an expression, but in the display frame of reality, represent to produce the needle downing position of site error with redness, represent needle downing position that does not produce site error etc. with black, thereby can discern.Certainly, have or not site error, do not limit display packing as long as can discern.
Utilize above-mentioned processing, the CPU 41 of control part 40 works as the error indicative control unit.
In error image display frame, show enter key E.If press enter key E, then finish the demonstration of error image display frame, show to be used to make the picture (making picture) of operation.
Below, utilize Fig. 7 that the action of Sewing machines 1 is described.This control is undertaken by the control of CPU 41.
If the operator will make thing and be arranged in the travel mechanism 20, via the input of guidance panel 30, select stitch data 51, make the indication input of action beginning, then CPU 41 is set at initial value of zero (step S1) with pin counting number A.Then, if the operator carries out the action of entering into of pedal 8, then drive sewing machine electromotor 6 and make main axis rotation (step S2).
Be accompanied by the rotation of main shaft, utilize spindle encoder 7 to carry out the detection of main axis rotation angle.If the anglec of rotation of main shaft surpasses data output angle (step S3: be), then from stitch data 51, obtain the positional information (step S4) of next needle downing position.And, if surpassing feeding, the anglec of rotation of main shaft begins angle (step S5: be), then utilize X-axis encoder 28 and Y-axis encoder 29 to detect the anglec of rotation (step S6) of X-axis motor 25 and Y-axis motor 26, carry out feed motion (step S7) based on the positional information of the needle downing position of in step S4, obtaining then.
And, the X-axis motor of relatively in step S6, obtaining 25, the anglec of rotation of Y-axis motor 26 and based on the X-axis motor 25 of the positional information of its needle downing position in the stitch data 51, the anglec of rotation of Y-axis motor 26, calculation deviation X, deviation Y.At this moment, under the situation of in deviation X, deviation Y at least one more than or equal to the deviation of deviation detection threshold (step S8: be), judge with the pin that falls of the pin sequence number that falls of counting the identical value of A and produce site error, deviation X, the deviation Y of this needle downing position are recorded among the deviation record buffer memory device 44a, and as the pin sequence number that falls, with the counting value of A and this deviation X, deviation Y is corresponding and be recorded among the deviation record buffer memory device 44a (step S9).
Then, CPU 41 adds 1 (step S10) in the value of counting A.Any of deviation X, deviation Y all is less than or equal to (step S8: not), jump to the processing of step S10 under the situation of deviation detection threshold in step S8.
Then, whether judgement finishes (step S11) according to the pin that falls of the positional information of all needle downing positions of stitch data 51, is not having (step S11: not), be back to the processing of step S3 under the situation about finishing.Under the situation that all pins that falls finish (step S11: be), judge the pin that falls (step S12) that whether has record among the deviation record buffer memory device 44a.In deviation record buffer memory device 44a, under the situation of the pin that falls of existence record (step S12: be), carry out error image display frame and show processing (step S13), finish this then and make action.In deviation record buffer memory device 44a, there is not (step S12: not), finish to make action under the situation of the pin that falls of record.

(action effect of the Sewing machines of present embodiment)
According to present embodiment, judge based on the needle downing position of stitch data 51 and be formed under the situation of error between the needle downing position of making the stitching on the thing at CPU 41 more than or equal to deviation detection threshold D, CPU 41 judges that this needle downing position produces site error, the information of the error that this needle downing position and this needle downing position of storage representation is had in the deviation record buffer memory device 44a of EEPROM 44.In addition, CPU 41 shows error image display frame on display part 31.Therefore, the operator can grasp and have or not the needle downing position that produces site error, and which needle downing position can grasp the needle downing position that produces site error be.Therefore, needn't be used for determining, grasping the visual examination that easily produces the needle downing position of site error at tailoring pattern, the problem that a large amount of manpowers that are accompanied by visual examination and the detection that poor stitching quality takes place are omitted can be eliminated, the needle downing position that produces site error can be easily filtered out.
In addition, error image display frame, be presented at the position relation of each needle downing position that comprises in the stitch data 51, and by produce the needle downing position of site error with red display, do not produce the needle downing position of site error with black display, have or not site error with discerning thereby utilize Show Color to show.Thus, the operator can grasp which needle downing position that is comprised more clearly and produce site error in being formed at the stitching of making on the thing.And, when repeatedly making action, suppose under the situation about comparing in the position of making generation site error in the action separately, the contrast that can easily produce the needle downing position of site error, very effective for the needle downing position of determining, grasp easy generation site error.
In addition, for the error that is used to judge site error, judge and judge at following two errors and have or not site error, that is: with the point of origin P benchmark, the absolute position of each needle downing position of in stitch data 51, setting and be formed on error (absolute position error) between each needle downing position of the stitching of making on the thing; And in stitch data 51 relative position relation between the needle downing position of two continuous positions and be formed on error (the relative position error) between the relative position relation between the needle downing position of the corresponding stitchings of needle downing position in the stitching of making on the thing and these two positions.Under the situation of utilizing the absolute position error, CPU41 detects the site error of distance in the precalculated position of making the stitching that forms on the thing.Utilizing under the situation of the relative position error, CPU 41 detects the site error of the needle downing position that makes the tailoring pattern distortion that is formed by stitching.In addition, before judging site error of generation by absolute positional relation, utilize absolute positional relation to judge, after judgement has produced the absolute position error, utilize relative position relation to judge, even thereby needle downing position owing to absolute position error of generation afterwards all produces site error in absolute positional relation, and do not produce under the situation of site error at the relative position relation that is used for forming stitching between continuous needle downing position, can judge not produce site error.That is,, can carry out the judgement of flexible more site error, can easily judge by the decision condition of operator's desired position error by site error is judged in sum of errors the relative position error combination in absolute position.
In addition, travel mechanism 20 has: X-axis motor 25 and Y-axis motor 26, and they make lower plate 21 and cloth pressing 22 move along X-Y plane; X-axis encoder 28 and Y-axis encoder 29, they are separately positioned on X-axis motor 25 and the Y-axis motor 26, detect the anglec of rotation of the rotating shaft of each motor, 41 couples of CPU compare based on the anglec of rotation of the X-axis motor 25 of stitch data and Y-axis motor 26 with by the anglec of rotation of X-axis encoder 28 and Y-axis encoder 29 detected X-axis motor 25 and Y-axis motor 26, calculation deviation X, deviation Y judge to have or not site error.Thus, can carry out error-detecting, judge thereby can carry out site error based on clear and definite and accurate error-detecting based on the numerical error of mechanical organ.
(other)
In addition, Sewing machines of the present invention in the scope that does not break away from feature of the present invention, also can form the embodiment different with above-mentioned embodiment.
For example, handle the various processing of carrying out by software, also can be provided for bearing the isolated plant of its part or a plurality of processing for CPU 41.In addition, also can be undertaken by analog circuit.
The error-detecting of needle downing position also can be undertaken by other method.For example, the sensor (linear transducer etc.) that other kind is set be can enumerate on Sewing machines 1, the lower plate 21 and the X-direction of cloth pressing 22, the methods such as position of Y direction detected.As long as can detect the X-direction of lower plate 21 and cloth pressing 22, the position of Y direction, also can utilize the sensor of other kind etc.
In addition, in above-mentioned example, carry out the detection of needle downing position in the next one timing of pin before beginning that fall, but be not limited thereto, for example, also can detect needle downing position in the timing before the suture needle that descends arrives cloth.Under this situation regularly, can more effectively detect the site error that causes because of the influence of moving the inertia after just stopping at cloth.In addition, the suture needle that descends has just arrived the timing before the cloth, because of fabric thickness different, but can detect by the fixing timing of the arrival of the suture needle under the average thickness of obtaining in advance main shaft angle, also can import fabric thickness in advance, obtain suture needle thus and arrive the main shaft angle, detecting with the corresponding timing of fabric thickness.
