The following describes the control system of Sewing machines 1.As shown in Figure 1, control device 150 substantially is made of CPU151, RAM152, ROM153, calculation processing apparatus with system busbar that they are coupled together.And, control device 150 also have display frame display unit (for example, LCD) 154, be located at the touch panel 155 on display unit 154 display surfaces and be used to indicate the operating pedal 156 of making beginning.
In ROM153, store and be used for controlling the control program of Sewing machines 1 and the control data that uses at this control program.CPU151 calculates as the working region and according to the control program that is stored among the ROM153 with RAM152, and carries out various computings according to the signal from touch panel 155 or encoder 157 inputs.In addition, CPU151 corresponding to the signal of result of calculation to Spindle Motor 14, shank rotary actuator 20, send button motor 32, button height adjust motor 35, work feed motor 51, differential motor 72, electromagnetic valve 108 and display unit 154 outputs.Control device 150 with this to Spindle Motor 14, shank rotary actuator 20, send button motor 32, button height adjust motor 35, work feed motor 51, differential motor 72, tongue piece cylinder 66, button rotation cylinder 37 and display unit 154 are controlled, and Sewing machines 1 (promptly, eedle up-down mechanism 10, needle bar swinging mechanism 11, button differential attachment 70, button rotating mechanism 46, button Height Adjustment mechanism 40, send deduction structure 30, and cloth feeding mechanism 50) carries out making (the following nail catcher that simply is called) or tie around button and to make relevant action with the floating seam that button is floated over the state on the cloth.
Describe in detail to make and make below with reference to Fig. 6 or Fig. 7 and (nail catcher is made and made and call nail catcher and make around the button knot around the button knot around button knot with the nail catcher of Sewing machines 1.)。Fig. 6 is the side view of button 200 and the position relation of cloth 300 when being illustrated in nail catcher and making.Fig. 7 is that the position that is illustrated in button 200 and cloth 300 when button knot is made concerns vertical view.In addition, below, to making as button 200 (forming porose 201,202,203,204 on the button 200) and nail catcher with four hole buttons is that parallel sewing (repeat successively after the pin that falls of hole 201 and 202, and repeat making to hole 203 and 204 successively with falling pin) describes.In addition, in Fig. 6, arrange for front and back in hole 201 and hole 202, and also arrange for front and back in hole 203 and hole 204, and arrange for the diagonal angle in hole 201 and hole 204.
At first, the operator comprises that the leading section ground of tongue piece 57 is positioned at cloth on the tongue piece 57, and draws in output cylinder bar 66a with tongue piece cylinder 66, and tongue piece support sector 59 is to having hanged rotation.Therefore, the leading section of tongue piece 57 moves to spring clamping part 60a, 60a, and cloth and tongue piece 57 together are clamped on spring clamping part 60a, the 60a.At this moment, pin hole 57b sees almost consistent with pin hole 60b from above-below direction.To the cloth of such location, be configured near the leading section of tongue piece 57 (that is, cloth maintaining part 60 near) being clamped in button 200 in the chuck portion 90.
After cloth 300 is positioned on the cloth maintaining part 60, be held in the button 200 in the chuck portion 90, move to position as shown in Figure 6 by button travel mechanism 100, and cloth 300 is moved to position shown in Figure 6 by cloth feeding mechanism 50.That is, cloth feeding mechanism 50, cloth 300 move to make pin hole 60b and pin hole 57b be positioned at eedle 5 under, simultaneously button travel mechanism 100 moves into place button 200 under eedle 5.Describe the action of button travel mechanism 100 in detail, promptly be that button rotation mechanism 46 is flat condition to button 200, and button Height Adjustment mechanism 40 from cloth 300 leave certain intervals (below, this is called button height j (as shown in Figure 7) at interval) button 200 is moved to the top of cloth 300, and, button differential attachment 70 and send deduction structure 30 button 200 move to make button 200 central part (that is cornerwise cross part in the diagonal in hole 201 and hole 204 and hole 203 and hole 204) be positioned at eedle 5 under.The preparation of nail catcher like this, just is through with.
Then, needle bar swinging mechanism 11 make eedle 5 be positioned at hole 201 directly over the position.And, eedle up-down mechanism 10 together moves back and forth up and down eedle 5 and shank 9, and cloth feeding mechanism 50 is keeping button 200 and cloth 300 relative relation ground, position that cloth 300 is moved back and forth forwards, backwards, send deduction structure 30 that button 200 is moved back and forth forwards, backwards simultaneously.Therefore, eedle 5 replaces the pin that falls on hole 201 and hole 202, and upper thread worn hang between button 200 and the cloth 300 (below, call left side seam and buckle line 205 wearing the line that hangs between hole 201 and hole 202 and the cloth 300).And button 200 moves forward and backward with cloth 300, be eedle 5 from the hole 201 and hole 202 when the Shang order goes out, carry out.
After the sewing finishing to hole 201 and 202, needle bar swinging mechanism 11 make eedle 5 be positioned at hole 204 directly over the position.Then, eedle up-down mechanism 10 together moves back and forth eedle 5 and shank 9 up and down, and cloth feeding mechanism 50 is keeping button 200 and cloth 300 relative relation ground, position that cloth 300 is moved back and forth forwards, backwards, send deduction structure 30 that button 200 is moved back and forth forwards, backwards simultaneously.Therefore, eedle 5 replaces the pin that falls on hole 203 and hole 204, and imposes right seam button line 206 make on hole 203 and hole 204 and cloth 300.
After the sewing finishing to hole 203 and hole 204, tangent mechanism cuts off upper thread, and button rotating mechanism 46 makes button 200, and the opening 56a place of lower plate 56 (promptly) hangs at the rear of cloth 300 (in other words, the front end of tongue piece 57).Like this, the position relation that button 200 and cloth 300 are relative just as shown in Figure 7.Then, needle bar swinging mechanism 11 moves eedle 5, cloth feeding mechanism 50 moving cloths simultaneously, and place with this eedle 5 left side seam button line 205 near root (left side seam is buckled line 205 and passed the position of cloth 300) directly over.At this moment, send deduction structure 30 also keeping the relative mobile button 200 in relation ground, position of button 200 and cloth 300.
Then, eedle up-down mechanism 10 together moves back and forth eedle 5 and shank 9 up and down, and needle bar swinging mechanism 11 and eedle up-down mechanism 10 interlocks, and eedle 5 and shank 9 one is coexisted swing on the seam button line 205,206.Like this, eedle 5 repeats alternately to descend in the ground, right side that the left side and the right seam of left side seam button line 205 are buckled line 206.At this moment, when cloth feeding mechanism 50 is keeping button 200 and cloth 300 relative relation ground, position that cloth 300 is moved forward, send deduction structure 30 that button 200 is moved forward.Like this, from needle falling point P1 to button 200 with the word shape make and reel around button line 207 that a left side seam buckle line 205 and right seam buckle on the line 206, and form this making of word shape stitching around detaining to tie.
Around the button sewer after be through with near the button 200, eedle 5 moves up and down and swings on one side, cloth feeding mechanism 50 keeps the relative relation ground, position of button 200 and cloth 300 mobile backward on the contrary cloth 300 on one side, send deduction structure 30 mobile backward on the contrary button 200 simultaneously.With this, from implementing to make to needle falling point P2 near the button 200 around the button knot.
The action of Sewing machines 1 is controlled Spindle Motor 14, shank rotary actuator 20, is sent button motor 32, button height adjust motor 35, button rotation cylinder 37, work feed motor 51, tongue piece cylinder 66 and differential motor 72 by control device 150 usefulness CPU151 as mentioned above.
The following describes around the button knot and make.Fig. 8 is divided into from make (that is the making when, button 200 and cloth 300 forwards mobile of cloth 300 to button 200 making around the button knot.Below being called moves ahead makes.Shown in Fig. 8 (a).) and from make (that is the making when, button 200 and cloth 300 rearward mobile of button 200 to cloth 300.Below be called to return and make.Shown in Fig. 8 (b)) skeleton diagram.And, as shown in Figure 7, illustrate distance cloth 300 front ends apart from the g part and apart between the distance h part of button 200, implemented to make around button knot.And, below, the zone of implementing around the button knot is made is called area I, and area I from the length of cloth direction (being fore-and-aft direction) as length i.As can be seen from Figure 7, button height j=is apart from g+ distance h+length i.
Moving ahead to make and return to make simultaneously is divided into three when regional making around the button knot at cloth feeding direction, the pin number of times that falls of the per unit length of cloth feeding direction (below, be called line density) all different in each zone.Make moving ahead, the regional A of cloth 300 sides (length of the cloth feeding direction of regional A be length a), the line density of the area B (length of the cloth feeding direction of area B is length b) between the zone C (length of the cloth feeding direction of zone C is length c) of button 200 sides, regional A and the zone C has nothing in common with each other.Equally, make returning, the line density of the area E (length of the cloth feeding direction of area E is length e) between regional F (length of the cloth feeding direction of regional F is length f), region D and the regional F of the region D of button 200 sides (length of the cloth feeding direction of region D is length d), cloth 300 sides has nothing in common with each other.And, length i=length a+ length b+ length c=length d+length e+ length f.
Concrete is, eedle 5 every swings once (promptly, eedle 5 drops to the right-hand decline (or buckle the left of line 205 from decline from right-hand the dropping at left side seam of buckle line 206 at right side seam) of buckle line 206 at right side seam from the left at left side seam button line 205) button 200 and the amount of feeding of the fore-and-aft direction of cloth 300 (below, only be called spacing), all different in each regional A～F.In detail, i.e. the spacing Pc of the spacing Pa of regional A and zone C, its spacing Pb than area B is little, and the spacing Pd of region D and the spacing Pf of regional F are littler than the spacing Pe of area E.That is, the line density of regional A and zone C is bigger than the line density of area B, and region D and regional F line density are bigger than the line density of area E.And spacing Pa can equate also that with spacing Pc spacing Pd also can equate with spacing Pf.In addition, length d is different with length c, and length d is littler than length c.In addition, length a is different with length f, and length f is longer than length a.In a word, make difference switching time of its spacing moving ahead to make and return.
In order to reach aforesaid purpose, control device 150 is carrying out when the button knot is made, as control eedle up-down mechanism 10 (Spindle Motor 14), needle bar swinging mechanism 11 (shank rotary actuator 20), cloth feeding mechanism 50 (work feed motor 51) and send deduction structure 30 (sending button motor 32) followingly.At first, control device 150 control eedle up-down mechanism 10, needle bar swinging mechanism 11, cloth feeding mechanism 50 and send deduction structure 30, make eedle 5 drop to needle falling point P1 (make to call to begin to reinforce make) to this.Then, control device 150 control send deduction structure 30 and cloth feeding mechanism 50, make send deduction structure 30 button 200 forwards a displacement g and cloth feeding mechanism 50 300 of clothes displacement g forwards.At this moment, control device 150 control eedle up-down mechanism 10 and needle bar swinging mechanisms 11 make needle bar swinging mechanism 11 eedle 5 swing slightly left, and eedle up-down mechanism 10 descend eedle 5.
Subsequently, control device 150 control eedle up-down mechanism 10 and needle bar swinging mechanisms 11 eedle up-down mechanism 10 is moved back and forth eedle 5 up and down, and needle bar swinging mechanism 11 are swung eedle 5 to the left and right.In the process that moves up and down that repeats eedle 5, control device 150 is controlled cloth feeding mechanisms 50 and is sent deduction structure 30, make cloth feeding mechanism 50 in eedle 5 every swings once spacing Pa of cloth 300 feeding forwards, and send deduction structure 30 in eedle 5 every swings once spacing Pa of button 200 feeding forwards.Like this, the zigzag that is spaced apart spacing Pa that imposes between hole 201 and hole 203 at regional A is made (making around the button knot).
Reach the first spacing change of location Y1, and the zigzag of the regional A that is through with make after (promptly, moved from make beginning button 200 and 300 of clothes around button knot ' after g+ length a '), control device 150, control cloth feeding mechanism 50 and send deduction structure 30, make the amount of feeding of each swing change to Pb.Concrete is, during in eedle 5 declines and in swing next time, if 300 of button 200 and clothes have been fed spacing Pa, then when eedle 5 drops to area B next time, control device 150, control cloth feeding mechanism 50 and send deduction structure 30, the amount of feeding of each swing is next time changed to spacing Pb.Then, control device 150 control cloth feeding mechanisms 50 and send deduction structure 30 make cloth feeding mechanism 50 cloth 300 a pitch of feed Pb forwards, and send deduction structure 30 that button 200 is swung a pitch of feed Pb forwards in each of eedle 5.Certainly, control device 150 is proceeded the driving up and down of eedle up-down mechanism 10 and the balancing point of needle bar swinging mechanism 11 and is driven.With this, make in the zigzag that is spaced apart spacing Pb that area B imposes between hole 201 and hole 203.
From making around the button knot, 300 of button 200 and clothes forwards moved ' apart from g+ length a+ length b ', and when arriving the second spacing change of location Y2, control device 150, control cloth feeding mechanism 50 and send deduction structure 30, make the amount of feeding of each swing change to spacing Pc.With this, make in the zigzag that is spaced apart spacing Pc that zone C imposes between hole 201 and hole 203.
From making around the button knot, 300 of button 200 and clothes have forwards moved ' apart from g+ length a+ length b+ length c ', and when arriving the 3rd spacing change of location Y3,150 of control device send the feeding side f of deduction structure 30 and system cloth feeding mechanism 50 to being converted to the rear.And in the process that moves up and down that repeats eedle 5, control device 150 is controlled cloth feeding mechanisms 50 and is sent deduction structure 30, make cloth feeding mechanism 50 in eedle 5 every swings once spacing Pd of cloth 300 feeding forwards, and send deduction structure 30 in eedle 5 every swings once spacing Pd of button 200 feeding forwards.With this, begin to return and make, and make in the zigzag that is spaced apart spacing Pd that region D imposes between hole 201 and hole 203.
Make from returning, 300 of button 200 and clothes forwards move ' length d ', and when arriving the 4th spacing change of location Y4, control device 150 is controlled cloth feeding mechanism 50 and sent deduction structure 30, makes the amount of feeding of each swing change to Pe.With this, make in the zigzag that is spaced apart spacing Pe that area E imposes between hole 201 and hole 203.And, to make from returning, 300 of button 200 and clothes have forwards moved ' length d+length e ', and when arriving the 5th spacing change of location Y5, control device 150 is controlled cloth feeding mechanism 50 and is sent deduction structure 30, makes the amount of feeding of each swing change to Pf.With this, make in the zigzag that is spaced apart spacing Pf that regional F imposes between hole 201 and hole 203.When regional F finished to make in a zigzag, control device 150 control eedle up-down mechanism 10, needle bar swinging mechanism 11, cloth feeding mechanism 50 and send deduction structure 30 made eedle 5 drop to needle falling point P2 and (this are made to call to finish to reinforce make.)。
As mentioned above, on seam button line 205,206, implement to make and return and make making of constituting around buckle to tie by moving ahead.
As on the above-mentioned Sewing machines 1, can carry out the data setting of various project, so that on cloth, follow closely the style of the button or the change nail catcher of different shape.That is, implemented nail catcher before the button knot is made, on display unit 154, show setting picture shown in Fig. 9 (a) and (b) by control device 150 at Sewing machines 1.Seen the method for the operator of picture, can import the data of each project with operation (touch) touch panel 155.Control device 150 is according to importing Data Control Spindle Motor 14, shank rotary actuator 20, sending button motor 32, button height adjust motor 35, button rotation cylinder 37, work feed motor 51, tongue piece cylinder 66 and differential motor 72.

The operator (is to touch the touch panel 155 that shows projects icon 404～416 parts in fact, to touch project icon 404～416.Below, identical when touching icon with it.) set numerical value corresponding to the project of projects icon 404～416.For example, when the operator touched project icon 410, display frame just switched to the picture shown in Fig. 9 (b).That is, project display part 401 is converted to numerical value input display part 417.On numerical value input display part 417, showing " 0 "～numerical value icon (ellipsis), carriage return icon 418 and the project icon 419 of " 9 ".Project icon 419, the icon with touching at Fig. 9 (a) of expression is the same.The operator is to touch the numerical value icon of " 0 "～" 9 ", can import the numerical value of project (in Fig. 9 (b), being length C) corresponding to project icon 419, and at last to touch carriage return icon 418, the numerical value of project settings for importing corresponding to project icon 419.In addition, in case touched carriage return icon 418, then display frame just is converted to the picture shown in Fig. 9 (a).And,, be that control device 150 carries out the demonstration signal being exported to display unit 154 by CPU151 according to the signal (corresponding to the signal that touches part) from touch panel 155 outputs to Fig. 9 (a) or (b) conversion of picture.And control device 150 carries out by CPU151 according to the numerical value from the signal identification operator input of touch panel 155 output, and carries out the setting value of projects this numerical value is stored among the RAM152.
Below, the handling process of the control device 150 that is calculated by CPU151 is described, and with reference to the action with the Sewing machines 1 of this processing of the process description of Figure 10.At first, by control device 150 picture as Fig. 9 (a) is presented on the display unit 154, and judges by control device 150 whether the operator has trampled operating pedal 156 (whether having exported connection signal from operating pedal 156) (step S1).When (step S1: in the time of not), control device 150 does not judge whether the operator has touched touch panel 155 and imported the numerical value (data) (step S2) of projects in the picture shown in Fig. 9 (b) from operating pedal 156 output connection signals.When control device 150 is judged as the operator when having imported the numerical value (step S2: be) of projects, projects are set at the numerical value (step S3) of input with control device 150 and the processing of control device 150 enters step S1.When the operator did not import the numerical value (step S2: deny) of projects, the processing of control device 150 then entered step S1.Before operating pedal 156 is trampled by the operator, the processing of control device 150 repeating steps S1～step S3, and set the numerical value of importing projects.
When operating pedal 156 was trampled (step S1: be) by the operator, the processing of control device 150 then entered step S4.In addition, when the operator did not import the numerical value of projects and trampled operating pedal 156, control device 150 was set at projects and gives the default value that is stored in ROM153 earlier.In step S4, control device 150 according to every destination data (that is, numerical value or the default value imported), calculates to make with nail catcher and tie around button and makes relevant needle downing position etc.At this moment, control device 150 is used from button height j to deduct length a, length c, calculate length b apart from the method for g and distance h, and uses from button height j and deduct length d, length f, calculate length e apart from the method for g and distance h.
Then, control device 150 is controlled Spindle Motor 14, shank rotary actuators 20, is sent button motor 32, button height adjust motor 35, work feed motor 51, differential motor 72 and electromagnetic valve 108, and implements above-mentioned nail catcher (step S5) with this.
Then, control device 150 control button rotation cylinder 37 turn to outstanding state (step S6) to button 200 from flat condition by button rotating mechanism 46.Then, control device 150 carries out the above-mentioned control (step S7) of making that begins to reinforce.Then, control device 150 control Spindle Motor 14, shank rotary actuators 20, send button motor 32 and work feed motor 51 (step S8), and by eedle up-down mechanism 10, needle bar swinging mechanism 11, send deduction structure 30 and cloth feeding mechanism 50 to go into the above-mentioned zigzag of implementing spacing Pa at regional A like that to make.Then, the order change (step S9～step S13) by spacing Pb, spacing Pc, spacing Pd, spacing Pe, spacing Pf of the amount of feeding that button motor 32 and work feed motor 51 make the pin that falls is each time sent in control device 150 control.With this, use by eedle up-down mechanism 10, needle bar swinging mechanism 11, send deduction structure 30 and cloth feeding mechanism 50 to implement in proper order to make in a zigzag at area B, zone C, region D, area E and regional F successively.Then, control device 150 carries out the control (step S14) that above-mentioned end reinforcing is made.
As mentioned above, in the present embodiment, as shown in figure 11, after making around the button knot, seam button line 205,206 is tied tight around buckle knot sewing line (that is the line that twines with eedle 5 at seam) 207 when the button knot is made.Particularly, in regional A (regional F), zone C (region D) since be wrapped on the seam button line 205,206 to tie sewing line 207 more around buckle, so near the seam button line 205,206 button 200 and cloth 300 is tied tight solidly.Therefore, button 200 can fully keep the state that hanged with respect to cloth 300, and the nail catcher of implementing to have aesthetic property is made.On the other hand, owing to be wrapped in less on the seam button line 205,206,, also shortened to tie and made the required time around button so not only controlled the use amount of suture around buckle knot sewing line 207 in area B (area E).In addition, even area B (area E) be wrapped on the seam button line 205,206 to tie sewing line 207 less around buckle, if but be wrapped in button 200 with respect near the seam button line 205,206 the cloth 300 to tie sewing line 207 more around buckle, then seam button line 205,206 can fully be kept the state of having hanged, and keeps the hanged state of button 200 with respect to cloth 300.In a word, use present embodiment, can reach and both can implement to have making of aesthetic property, can boost productivity and reduce the purpose of use cost again around the button knot.
In addition, in the present embodiment, as shown in Figure 8, can consider think button 200 sides around button knot sewing line 207 density big near button 200 to the second spacing change of location Y2 as the first area, and think the cloth side around button knot sewing line 207 density big near cloth 300 to the 5th spacing change of location Y5 as second area, and other parts as the 3rd zone.
In addition, in the present embodiment, as shown in Figure 8, the spacing change of location that making moves ahead makes is with to return the spacing change of location of making different.Promptly, the move ahead spacing change of location Y1 that makes and the return spacing change of location Y5 that make corresponding with it has deviation at fore-and-aft direction, and move ahead the spacing change of location Y2 that makes and the return spacing change of location Y4 that make corresponding with it also have deviation at fore-and-aft direction.
(other embodiment)
In the above-described embodiments, be to swing eedle 5 to the left and right basically, so that the left and the right seam that make the needle downing position of eedle 5 alternately be repeated on left side seam button line 205 are buckled the right-hand of line 206 at needle bar swinging mechanism 11 in the button knot is made.That is, (spacing is to descend at the left of left side seam button line 205 amount of feeding to descend during right side seam is buckled line 205 right-hand button 200 and cloth 300 from eedle 5 in each spacing.) go up eedle 5 declines once.But, also can on each spacing, descend repeatedly by eedle 5.That is, control device 150 also can be controlled needle bar swinging mechanism 11, makes the eedle 5 that descends at least a time between left side seam button line 205 or right seam are buckled line 206 or they.For example, shown in Figure 12 (a), if needle downing position 1. (right seam button line 206 right-hand needle downing position) and needle downing position 4. (needle downing position of buckleing line 205 lefts is stitched on a left side) as the needle downing position of full swing amplitude, then control device 150 control eedle up-down mechanism 10, needle bar swinging mechanism 11, send deduction structure 30 and cloth feeding mechanism 50, make eedle 5 by needle downing position 1.～needle downing position order 7. descends.And, shown in Figure 12 (b), if needle downing position 1. with needle downing position 5. as the needle downing position of full swing amplitude, then control device 150 control eedle up-down mechanism 10, needle bar swinging mechanism 11, send deduction structure 30 and cloth feeding mechanism 50, make eedle 5 by needle downing position 1.～needle downing position order 9. descends.Eedle 5 is at left side seam button line 205 or right seam buckles line 206 or which the regional decline between them can, but particularly (perhaps in the initial swing of area B or area E and a last swing, at regional A, zone C, region D or regional F), preferably eedle 5 descends between left side seam button line 205 or right seam are buckled line 206 or they.Under above situation, decline how many times eedle also can be set with touch panel 155 between two needle downing positions that constitute the full swing amplitude.
If eedle 5 descends between left side seam button line 205 or right seam buckles line 206 or they, the effect that the line of making around the button knot that then can obtain to make rear region A, zone C, region D or regional F is not offset to area B or area E.Therefore, because near the seam button line 205,206 cloth 300 and button 200 is maintained at the state of tying tight solidly, so seam button line 205,206 is maintained at the state that has hanged with respect to cloth 300.That is to say, keeping and have button 200 by the nail catcher of the aesthetic property of cloth 300.
In addition, the present invention is not limited to the foregoing description, as long as without departing from the spirit and scope of the present invention, also can carry out the change of various improvement and design.
For example, though used the touch panel 155 that is used to import projects numerical value, also can use the input unit of keyboard, mouse or guidance panel etc. to replace touch panel 155.
In addition, nail catcher is made and is not limited to parallel making, and also can make (repeating successively to repeat the pin that falls to hole 202 and hole 203 successively behind the pin that falls in hole 201 and hole 204) with cross, and also can be with other nail method.In addition, button also is not limited to four hole buttons, also can be two hole buttons.In addition, cloth 300 and button 200 are to distinguish feeding forwards, backwards by independent drive source, but also can use same drive source.
In addition, in the above-described embodiments, be with shank rotary actuator 20 make to the left and right swing of eedle 5, with send button motor 32 make button 200 forwards, backwards the moving of direction, make button 200 the moving and make cloth 300 direction mobile and carry out the change of the relative position of eedle 5 and button 200 forwards, backwards of direction to the left and right with differential motor 72 with work feed motor 51.But, also can not swing with eedle 5, and only button 200 and cloth 300 forwards, backwards left and right directions move, 300 pairs of eedles 5 of button 200 and cloth are relatively moved, that is, as long as the relative position of change eedle 5 and button 200.
In addition, make moving ahead, be three zones that are divided into regional A, area B, zone C, and make returning, and is three zones that are divided into region D, area E, regional F, but also can the different zone of spacing divide more.Certainly, even regional change is many, near the zone button 200 and cloth 300, preferably its per unit length ties number of times tying often around button than other zones around button.
And, the number of regions of making of moving ahead with return the number of regions of making and need not be identical number, for example, as described in present embodiment, change the words of spacing that move ahead and make the zone at regional A, B, C with regard to having met the demands, then make returning, just the change of spacing can be do not carried out on the way,, then sewing speed can be improved if use the same big spacing to make with area B, and can boost productivity, and reduce the use amount of suture.
In addition, in above-mentioned present embodiment, the setting that having carried out respectively moves ahead makes and return the setting of making, but also can only carry out a side setting and the opposing party is reflected a side setting.Promptly, for example, also can be respectively applied for length f and spacing Pf among the regional F to length a and spacing Pa, the setting of length b and spacing Pb is respectively applied for length e in the area E and spacing Pe, length c and spacing Pc are respectively applied for length d and spacing Pd in the region D.
In addition, in above-mentioned present embodiment, strengthen near the button 200 and near the cloth 300 density with the method for change spacing around button knot sewing line 207, but be not limited to the change of spacing, for example, also can make coming and going repeatedly to carry out in a zigzag near the button 200 and before and after near the cloth 300 with same spacing, that strengthens like this ties the density of sewing line 207 around button.But, in this case down,, can carry out the nail catcher of shapeliness and tie around button and make so the method for distance falls in change because the part that comes and goes repeatedly is big than other parts.
(invention effect)
According to the present invention, because at least in the first area or a side of second area, at per unit length The decline of upper eedle is stitched the seam of detaining on the line so be wound in often in first area or second area Line is more, and near cloth or button seam button line is tied tight. In addition, because in the 3rd zone, The decline number of times of eedle is few on the per unit length, has not only controlled the use amount of suture, and has shortened Make the required time around the button knot. That is, owing near cloth or button, seam button line is tied tight, so Can realize implementing stitching the button line is fully kept with respect to the state that hanged of cloth and is had the nail of aesthetic property Button and boost productivity and reduce the purpose of the use cost of suture.
In addition, because the eedle that in seam button line, descends at least a time, so can prevent because passing through seam button line Suture and making make crooked around button knot. Therefore, can maintain near the seam button of tying tight cloth or the button The state of line, and keep seam button line with respect to the state that cloth has hanged, keep the nail catcher with aesthetic property.
