This apparatus for sewing 21 includes sewing machine body 25, feed rolls 26, feeding motor 27, operation panel 28, control loop 30 and feeding motor drive circuit 31.In these inscapes, constitute by operation panel 28, control loop 30, feeding motor drive circuit 31 and to send into size Control device 20.
As the sewing machine body 25 of making mechanism, be that ribbon 24 is made mechanism on cloth 23.Sewing machine body 25, with needle plate 35 and pressing plate 36 the cloth 23 (Fig. 3 and shown in Figure 4 on the summary horizontal supporting face that is placed on cloth supporting station 34, in Fig. 1 and Fig. 2, do not show) hold under the arm, with feed dog (figure does not show) it is sent towards the predetermined direction of making on one side, make pin towards the past double action of driving direction up and down on one side, like this, can make.In addition, in apparatus for sewing 21, ribbon 24 is admitted to sewing machine body 25, ribbon 24 can be sewn on the cloth 23.
As the feed rolls 26 of sending into mechanism, be the mechanism that ribbon 24 is sent into sewing machine body 25, specifically, be the mechanism that ribbon 24 is sent into the ribbon supply port of pressing plate 36, it has pair of rolls 38,39.In each roller 38,39, one of them roller 38 is bigger than the external diameter of another roller 39, and two rollers are around the axis rotation that is parallel to each other, and flexibly rotation then and linkedly mutually.These each rollers 38,39 are being seized ribbon 24 rotations on both sides by the arms, like this, ribbon 24 can be sent into sewing machine body 25.
As the feeding motor 27 of sending into driving mechanism, be the mechanism that feed rolls 26 rotations are driven, for example it can be a stepper motor.This feeding motor 27 makes any the roller rotation in each roller 38,39, in this example, is to make roller 38 rotations, and like this, another roller 39 rotates also drivenly.
Comprise the ribbon feed arrangement of feed rolls 26 and feeding motor 27, be installed on the sewing machine body 25.Above sewing machine body 25, be provided with for example be bearing on the pillar (figure do not show), be called the ribbon feedway (scheming not show) of be with auto-feeder.The ribbon feed arrangement can be sent into sewing machine body 25 to the ribbon of supplying with from the ribbon feedway 24.
Fig. 5 is the front elevation of expression operation panel 28.As shown in Figures 1 to 4, operation panel 28 include input block 40, as the display part 41 of indication mechanism.Input block 40 is mechanisms that input requires size, and this requires size is the size that will be sewn on the ribbon 24 of presumptive area on the cloth 23.Comprising the information of being imported by input block that requires size, be sent to control loop 30, control loop 30 control display parts 41 show display part 41 and are comprising the information of being imported by input block 40 that requires size.
According to the different goods 22 of making, when being sewn into ribbon 24 on the cloth 23, particularly when making ribbon 24, exist sometimes ribbon 24 is applied tension force, makes in the part on the cloth 23 and ribbon 24 is not applied tension force, makes the part on cloth 23 with nature with elongation state with elastic extension.The former partly is in order to form wrinkle on the cloth after making 23, to make cloth 23 be contraction-like; The latter partly is in order not form wrinkle on the cloth after making 23, to make cloth 23 be open and flat shape.At this moment, in the apparatus for sewing 21, according to the state after finishing, in other words according to when making, ribbon 24 being applied tension force, the Zone Full of making ribbon 24 on the cloth 23, be divided into several regional parts, each area part has operation separately, makes like this.For example, when the bottom of s trouser leg oral area of female pants shown in Figure 3 is provided with elastic cord, be divided into the 1st～the 3rd such three operations.
Setting tension force in each operation, be in each operation, when on the area part of correspondence, making, to the tension force that ribbon 24 applies, be the operation sequence number for the 1st in the 1st operation of " 1 " set tension force, operation sequence number for the 2nd in the 2nd operation of " 2 " set tension force ..., the operation sequence number is that n in the n operation of " n " sets tension force.Therefore, in the example of Fig. 3, import the 1st～the 3rd and set tension force.
Each inter process length (below be sometimes referred to as " feeding length "), be the lengthwise dimension that is sewn on the ribbon 24 on each operation institute corresponding region part, be in the 1st operation the 1st feeding length, the 2nd feeding length in the 2nd operation ..., the n feeding length in the n operation.Therefore, in the example of Fig. 3, import the 1st～the 3rd feeding length.Each feeding length is the size that does not apply the nature of tension force, and no matter the corresponding region part is open and flat part or constriction, all with finish after make measure-alike in the goods.This feeding length is equivalent to the requirement size, is during each sewing procedure action, should send into the size of the ribbon 24 of sewing machine body 25.
Revising setting value, is the correction value of sending into size that is used to revise feed rolls 26.In theory, each roller (sheet) 38,39 of sending into roller 26 whenever rotates a circle, can send into ribbon 24 with the full girth equivalent size of each roller 38,39, but, owing to reasons such as the retractility of ribbon 24 and materials, the size of the ribbon of sending into when each roller 38,39 rotates a circle 24, inequality with the full girth of each roller 38,39 sometimes.Being used for revising the value of this point, is exactly above-mentioned correction setting value, and this correction value is being with thing 24 to set to each.Girth described here is meant the Zhou Fangxiang size of outer peripheral face; Said full girth is meant along the Zhou Fangxiang size of the outer peripheral face in full week of roller 38,39 all directions.
Input information by input block 40 inputs is sent to control loop 30.Indication mechanism 41 controlled loops 30 controls can show this input information, so, when the above-mentioned input information of input,,, have convenience Yi Bian carry out input operation on one side can confirm the input information that shows.
In addition, control loop 30 has the function of sending into detecting unit.That is, storing the actuating quantity trace routine in advance in memory, CPU reads and carries out the actuating quantity trace routine, like this, detects the actuating quantity of feed rolls 26.Specifically, directly do not detect the actuating quantity of feed rolls 26, but the number of drive pulses of instrumentation instruction feeding motor 27 actions.The actuating quantity of this instrumentation umber of pulse Pcount as feeding motor 26.
In this example, feeding motor 27 is stepper motors, sends into motor drive circuit (below be sometimes referred to as " drive circuit ") 31 from 30 pairs of control loops and gives and driving pulse, sends instruction like this and makes 27 actions of feeding motor.Drive circuit 31 makes 27 actions of feeding motor be equivalent to certain rotation number of a driving pulse according to the instruction from control loop 30, in other words, makes the certain anglec of rotation of feeding motor 27 actions, just makes the output shaft rotation.Below, sometimes the rotation of output shaft is called the rotation of feeding motor 27.
Like this, give number of drive pulses with drive circuit 31 from control loop 30, corresponding with the actuating quantity of feeding motor 27, therefore, also be the value corresponding with the actuating quantity of feed rolls 26.In this example,, detect feeding motor 26 actuating quantities by this number of drive pulses of instrumentation.
In addition, control loop 30 has the function of computing unit.Promptly, storing required actuating quantity calculation procedure in memory in advance, CPU reads and carries out required actuating quantity calculation procedure, calculates required actuating quantity, this required actuating quantity is to send into and the actuating quantity of required feed rolls 26 for the corresponding ribbon of size 24 that requires of handle and input.Specifically, according to the 1st～the n feeding length of input, in each operation, obtain and set umber of pulse Pulse, as required actuating quantity.This sets umber of pulse Pulse, with for ribbon 24 umber of pulses that send into, that 27 rotations of feeding motor are required these the 1st～the n feeding lengths suitable.At this moment, consider the correction setting value of input, calculate.
More particularly, during each sewing procedure action, sending into sewing machine body 2
The size of 5 ribbon 24 is made as L, sets umber of pulse Pulse and can use following formula (1) to calculate.
Pulse＝(L/P)×C…(1)
P in the formula (1) is when a driving pulse is given with drive circuit 31, the girth of the feed rolls 26 suitable with the rotation number (anglec of rotation) of feed rolls 26.As previously mentioned, feed rolls 26 has the different pair of rolls of external diameter 38,39, and this pair of rolls 38,39 is rotated linkedly, so the girth corresponding with 1 pulse is identical.Above-mentioned girth is the value relevant with any roller, in this enforcement, is the girth relevant with roller 38.
In addition, the C in the formula (1) is the feeding correction value.This feeding correction value C, being used for revising the full girth of each roller 38,39, poor with the size of each roller 38,39 actual ribbon of sending into 24 when rotating a circle (below be sometimes referred to as " actual feeding size "), is the full girth of each roller 38,39 and the ratio of actual feeding size.
Below, be that example specifies with roller 38.If the full girth of a roller (sheet) 38 is X, the actual feeding of roller 38 is of a size of Y, and then feeding correction value C represents with formula (2).
C＝Y/X…(2)
Here, by the correction setting value of input block 40 inputs, can be feeding correction value C, also can be actual feeding size Y.The full girth X of roller 38 is sizes of machinery, is certain value, so, be stored in advance in the memory of control loop 30, also import the actual feeding size Y that causes variation by ribbon 24 by instrumentation, also can calculate feeding correction value C by control loop 30.Which kind of situation no matter, feeding correction value C can obtain according to the correction setting value of input.
In addition, control loop 30 has the function of judging unit.That is, storing determining program in advance in memory, CPU reads and carries out determining program, and the actuating quantity that detects (below be sometimes referred to as " detection actuating quantity ") is compared judgement with required actuating quantity.Specifically, control loop 30 aforementioned instrumentation to instrumentation umber of pulse Pcount and aforementioned setting umber of pulse Pulse compare, whether judge both consistent.
In addition, control loop 30 has the function of control module.That is, storing the motor control program in advance in memory, CPU reads and carries out the motor control program, and according to judged result, control feeding motor 27 makes feed rolls 26 carry out the action of aequum.Specifically, set tension force according to the 1st～the n, at the state that the tension force of this input is imposed on ribbon 24, driving pulse is given and drive circuit 31, this driving pulse makes 27 actions of feeding motor, ribbon 24 can be sent into like this.Drive circuit 31 according to the driving pulse from control loop 30, makes 27 actions of feeding motor.
Send into size Control device 20, have Sewing machines turn-sensitive device 45, this Sewing machines turn-sensitive device 45 is mechanisms of detecting the actuating quantity of sewing machine body 25.Specifically, driving shaft is used to drive the pin that is located on the sewing machine body 25 etc., detects the rotation number (anglec of rotation) of driving shaft, delivers to control loop 30.This Sewing machines turn-sensitive device 45 for example is provided in a side of the rotary encoder on the driving shaft of sewing machine body 25.When the angle that every rotation is scheduled to, produce pulse, control loop 30 is delivered in this pulse.
The tension force of ribbon 24 is meant in the position of being seized on both sides by the arms by needle plate 35 and pressing plate 36, and is fed roller 26 and seizes tension force between the position on both sides by the arms.If make feed speed and feed rolls 26 in the sewing machine body 25 to send into speed identical, then can ribbon not applied tension force; If make the feed speed of feed rolls 26, be lower than the feed speed in the sewing machine body 25, then can to ribbon 24 apply with its speed than corresponding tension force.Therefore, the setting tension force the tension adjustment of ribbon 24 is imported to each operation keeps this tension force, can send into ribbon 24.
When tension adjustment, also tension pick-up 46 can be set, this tension pick-up 46 detects the position of being seized on both sides by the arms by needle plate 35 and pressing plate 36 and is fed roller 26 and seizes tension force between the position on both sides by the arms.According to the detection tension force of this tension pick-up, control loop 30 sends instruction, makes 27 actions of feeding motor, becomes setting tension force.
Fig. 6 is a flow chart, and expression is by sending into the size Control method of sending into that size Control device 30 is carried out.Specifically, the control action of expression control loop 30.The state of above-mentioned input information having been imported at input block 40, in the sewing machine body 25 making the action beginning time, the control action in the control loop 30 enters step s1 from step s0.At step s1, the initial value of operation sequence number (operation No) is set at " 1 ", enter step s2.
At step s2, from memory, read in setting tension force, this setting tension force is set corresponding to the No operation.For example, when operation No is the 1st operation of " 1 ", reads in the 1st and set tension force; When operation No is the 2nd operation of " 2 ", reads in the 2nd and set tension force; , like this, read in the setting tension force of corresponding setting with operation.This setting tension force read in end after, enter step s3.
At step s3, from memory, read in feeding length, this feeding length is set corresponding to the No operation.For example, when operation No is the 1st operation of " 1 ", read in the 1st feeding length; When operation No is the 2nd operation of " 2 ", read in the 2nd feeding length; , like this, read in the feeding length of corresponding setting with operation.The feeding length that reads in like this, substitution should be sent into the size L of the ribbon 24 of sewing machine body 25 during this sewing procedure action, enter step s4.
At step s4, with above-mentioned formula (1), calculate with the corresponding operation of present operation No in setting umber of pulse Pulse, enter step s5.At step s5, with instrumentation umber of pulse Pcount reset.At this constantly, become the state of the setting tension force that reads at the tension force of ribbon 24, control loop 30, make with the corresponding operation of operation No in the feeding of ribbon 24 and the action of sewing machine body 25 synchronously begin, ribbon is sent into sewing machine body 25, and give and driving pulse to feeding motor drive circuit 31, then, before this operation finishes, feeding motor drive circuit 31 is given and driving pulse, make ribbon 24 and sewing machine body 25 action synchronously, send into with keeping setting tension force.
Then enter step s6,, judge whether feeding motor 27 rotates at step s6.Specifically, be to judge whether driving pulse is given and feeding motor drive circuit 31.When being judged as feeding motor 27 when not rotating, return step s6, be judged as before feeding motor 27 rotated, the action of step s6 repeatedly when being judged as feeding motor 27 when having rotated, enters step s7.
At step s7, judge that feeding motor 27 is towards positive veer, promptly sends into the direction rotation of ribbon 24 or towards reverse directions, promptly retract the direction rotation of ribbon 24.Specifically, be to judge the pulse of giving with feeding motor drive circuit 31, make it towards positive direction rotation or the driving pulse that rotates in the opposite direction.Why will carry out this judgement, be because feeding motor 27 is a tension force of regulating ribbon 24, sometimes slightly ribbon 24 past pulling back.
When feeding motor 27 is during towards the rotation of positive veer, enter step s8, to each pulse, on instrumentation umber of pulse Pcount, add " 1 ", enter step s10.If feeding motor 27 is when reverse directions is rotated, enter step s9, to each pulse, from instrumentation umber of pulse Pcount, deduct " 1 ", enter step s10.
At step s10, judge whether instrumentation umber of pulse Pcount is identical with setting umber of pulse Pulse.If inequality, then be judged as present operation and do not finish, return step s6.If identical, then be judged as present operation and finish, enter step s11.
At step s11, judge whether to exist subsequent processing.Specifically, be to judge whether present operation sequence number is identical with the process number of input.If inequality, then be judged as subsequent processing, enter step s12, on present operation sequence number, add " 1 ", return step s
2。If identical, then being judged as does not have subsequent processing, enters step s13, the finishing control action.
According to above-mentioned size Control device 20 and the control method sent into, drive feed rolls 26 by feeding motor 27, when ribbon 24 is sent into sewing machine body 25, feeding length according to the ribbon 24 that is input to each operation, control loop 30 calculates the umber of pulse Pulse that number of drive pulses is promptly set, and this number of drive pulses is suitable with the rotation number (anglec of rotation) of the required feeding motor 27 for the ribbon 24 of sending into this feeding length.In addition, control loop 30 gives number of drive pulses with drive circuit 31 by instrumentation, judge by control loop 30 whether this instrumentation umber of pulse Pcount is identical with setting umber of pulse Pulse, control back 30 control feeding motors 27, make the rotation number of feeding motor 27 suitable with setting umber of pulse Pulse.
Like this, by importing the feeding length that will make the ribbon 24 on cloth 23, the rotation number that 27 rotations of feeding motor can be sent into the ribbon 24 of this length makes feed rolls 26 rotations, ribbon 24 can be sent into.Therefore, even for example because of the operation condition of the sewing machine bodies such as rotary speed 25 of driving shaft or have or not the state etc. of superimposed etc. cloth 23 to cause the difference of making spacing, also can prevent the influence that size is subjected to above-mentioned difference of making of ribbon 24, can make ribbon 24 with high dimensional accuracy.And when realizing this high dimensional accuracy, the operator is as long as the input feeding length needn't consider that the operation condition of sewing machine body 25 and the state ground of cloth 23 carry out input operation, can make input operation very easy.
The tension force of the ribbon 24 when making on cloth 23, be applied between sewing machine body 25 at feed rolls 26, because the upstream side at feed rolls 26 does not apply tension force, so, even the setting tension force difference of each operation, the size of sending into respect to feed rolls 26 1 week rotation also keeps necessarily, and tension force does not influence sends into size, can easily control and send into size.Among the step s9 of Fig. 6, feed rolls 26 is counter-rotatings, and this is just for adjustment of tonicity, and in error range, control is easy to the influence of sending into size.
Above-mentioned example is only represented an example of the present invention, within the scope of the invention, can change its formation.For example, in the aforesaid example, control loop 30 is as sending into detecting unit, still, also can as shown in Figure 1 motor turn-sensitive device 29 be set additionally, with it as sending into detecting unit.This motor turn-sensitive device 29, the actuating quantity that detects feeding motor 27 is the rotation number (anglec of rotation) of feeding motor 27.The rotation number of detected feed rolls 26 is delivered to control loop 30.Specifically, motor turn-sensitive device 29 for example is provided in a side of the rotary encoder on the feeding motor 27, during the predetermined angle of every rotation, produces pulse, and control loop 30 is delivered in this pulse.At control loop 30, this pulse of instrumentation obtains the instrumentation umber of pulse.This instrumentation umber of pulse also is the value corresponding with the actuating quantity of feed rolls 26, can replace the instrumentation umber of pulse of instrumentation driving pulse, can carry out same control.
In addition, in the aforementioned example, requiring size is the size of feeding length of the every operation of input, still, also can not adopt and require size, but import size after the finishing of each operation.Size after finishing is that the area part of the cloth 23 of each operation correspondence is made size after finishing, is the size when not applying the nature of external force after making.Size after this is finished, also be and the corresponding value of size that during a sewing procedure action, should send into the ribbon 24 of sewing machine body 25, consider factors such as the material of cloth 23 and thickness, can be after finish size, obtain ribbon 24 sizes that during a sewing procedure action, should send into sewing machine body 25.Therefore, can carry out the control same with previous embodiment.
In the aforementioned example, be to have exemplified the example that some operations are arranged, but also be applicable to the situation of having only an operation, can reach excellent effect.In addition, in aforementioned example, be to adopt feed rolls as sending into mechanism, adopt the feeding motor as sending into driving mechanism, still be not limited to this, also can adopt other structure.In addition, send into the detection of size, also can not adopt and detect the rotation number of sending into motor, but adopt optical pickocff, directly detect the amount of sending into of ribbon.In addition, about cloth and ribbon, also can be the material beyond the previous example.
Scope not breaking away from the present invention's spirit and principal character can have other various examples.Therefore, aforementioned example only is to exemplify, and scope of the present invention is represented in the claims, not limited by specification.In addition, various distortion or change in the claim scope, all within the scope of the present invention.
