The present disclosure relates to a sewing machine that sews patterns by moving a cloth holding frame holding a workpiece cloth in an X direction and a Y direction respectively based on sewing data of a pattern selected by a user and a controller therefore. The controller determines a cloth feed start timing so that an X feed start timing to execute an X directional feed for every feed operation in each sewing operation precedes a Y feed start timing to execute Y directional feed based on the sewing data. The controller allows cloth feed execution without an upper thread being wound on the sewing needle.
Description
Technical field
The present invention relates to a kind of stitch data according to the selected pattern of operator makes the cloth that is keeping processing cloth keep frame to move the Sewing machines and the control device thereof of sewing pattern respectively on directions X and Y direction.
Background technology
In the past, electronic sewing machine make cloth keep processing cloth that frame kept with the directions X of main shaft quadrature and with the Y direction of spindle parallel on move sewing pattern independently.The various work feeds of controlling have been proposed so that all stitchings all become the control device of complete stitching (perfect stitch) when sewing pattern.
For example, Japan put down into control device that patent application in 6 years discloses the disclosed automated sewing Sewing machines of No. 31065 communique (the 3rd～5 page, Fig. 2, Fig. 4) make sewing pattern when (being equivalent to the pattern among the application) sewing data (being equivalent to the stitch data among the application) according to sewing pattern drive servo motor.Servo motor makes cloth keep frame to move on X, Y direction.Control device is made sewing pattern according to the order of sewing data usually.Produce when adding coiling mark (hitch stitch) in sewing data, control device is made sewing pattern (from oppositely making) according to the reverse order of sewing data.
In the control device of the disclosed automated sewing Sewing machines of above-mentioned communique, keep frame different to the order of directions X and the feeding of Y direction because of making cloth, upper thread interweaves (winding) sometimes to suture needle.Promptly produce and add the coiling mark.At this moment and since upper thread on draw impedance to become big, therefore can cause upper thread on draw badly, tightening up of line is poor, thereby has the problem that can't form beautiful stitching.
For example, in Figure 13, upper thread 9 from the rear (Y direction) forwards (+Y direction) pass the pinprick 18a of suture needle 18.Expression be suture needle 18 from previous needle downing position N0 to-directions X and-the next needle downing position Na of Y direction forms the situation of stitching.-directions X ,-the Y direction indication be court-directions X ,-Y direction work feed.Behind court-Y direction work feed at first again during court-directions X work feed, the situation below occurring.The upper thread 9 that passes pinprick 18a towards the place ahead is hooking behind the right side of suture needle 18 leading sections towards left, thereby is wrapped on the leading section of suture needle 18.Promptly produce and add the coiling mark.Under this winding state, processing cloth W is thrust in suture needle 18.At this moment, tightening up of line is poor, can't form beautiful stitching.
Figure 14 represents be suture needle 18 from previous needle downing position N0 to+directions X and-the next needle downing position Nb of Y direction forms the situation of stitching.Behind court-Y direction work feed at first again during court+directions X work feed, the upper thread 9 that passes pinprick 18a towards the place ahead is hooking behind the left side of suture needle 18 leading sections towards right-hand, thereby is wrapped on the leading section of suture needle 18.Promptly produce and add the coiling mark.Under this winding state, processing cloth W is thrust in suture needle 18.This moment, tightening up of line was poor, can't form beautiful stitching too.
Summary of the invention
The object of the present invention is to provide a kind of Sewing machines and control device thereof, to processing cloth when carrying out work feed, can not carry out work feed under the upper thread that passes the suture needle pinprick can not be wound into situation in the suture needle, tightening up of line is good, can form beautiful stitching.
The control device of the Sewing machines of the Sewing machines of technical scheme 1 and technical scheme 7 has: make mechanism, this is made mechanism and comprises suture needle and rotating shuttle on the shank, and with motor of sewing machine as drive source; And the actuation mechanism of frameing shift, this actuation mechanism of frameing shift can be in horizontal plane drives independently along the directions X of quadrature and Y direction will process the cloth that cloth remains on above the needle plate and keep frameing shift moving, described directions X is the direction towards quadrature of the pinprick that has with suture needle, described Y direction for the pinprick that has with suture needle towards parallel direction, come sewing pattern according to stitch data.The control device of Sewing machines is determined the work feed time started according to the stitch data of described pattern, to make X feeding time started along described directions X work feed early than the Y feeding time started along described Y direction work feed when respectively making the work feed of action at every turn.
Adopt said structure, arrive the pinprick of suture needle via thread take-up tension lever from the upper thread of line supply source, from the suture needle pinprick towards parallel direction, be that the rear side (Y direction side) of Y direction passes towards the front side (+Y direction side) of Y direction.Because control device carries out earlier carrying out along the work feed of Y direction along the work feed of directions X when respectively making the work feed of action again at every turn, the upper thread that therefore passes the suture needle pinprick towards the place ahead can not be wrapped in the suture needle, is positioned at left side or right side with respect to suture needle.
In the work feed of court-directions X, upper thread goes towards the left side from pinprick, and in the work feed of court+directions X, upper thread goes towards the right side from pinprick.Because control device is at the work feed that towards determine after carry out Y direction of the upper thread that extends from pinprick with respect to suture needle, though therefore Y direction work feed for-Y direction, with upper thread pass pinprick to pass direction opposite, upper thread can not be wrapped in the suture needle yet.Therefore, the stitching on the next needle downing position after work feed finishes smartens up, and tightening up of line becomes good.
The control device of the Sewing machines of the Sewing machines of technical scheme 2 and technical scheme 8 after the described X feeding time started with ormal weight along described directions X work feed, then along described Y direction work feed.
Adopt said structure, can prevent reliably that upper thread is wrapped in the suture needle.
In the control device of the Sewing machines of the Sewing machines of technical scheme 3 and technical scheme 9, the work feed judging part judges whether when work feed and can carry out work feed with the feeding amount that has increased the ormal weight work feed of described directions X on the basis of the feeding amount of described Y direction along the Y direction.In described work feed judgement section judges is can not work feed the time, and deceleration instruction portion sends instruction, slows down with the rotating speed to described motor of sewing machine.
Adopt said structure, owing to deceleration instruction portion slows down to the rotating speed of motor of sewing machine, so the generation of work feed time is more than needed, and the work feed that can carry out directions X reliably earlier carries out the work feed of Y direction again.
The control device of the Sewing machines of the Sewing machines of technical scheme 4 and technical scheme 10 has storing mechanism, but this storing mechanism stores the speed feeding amount information of the cloth feed amount correspondence of the rotating speed that makes described motor of sewing machine and Y direction, and described work feed judging part is judged according to stitch data and the speed feeding amount information that is stored in the storing mechanism.
Adopt said structure, even the rotation speed change of motor of sewing machine, the work feed judging part also can judge whether reliably can work feed.
In the control device of the Sewing machines of the Sewing machines of technical scheme 5 and technical scheme 11, the exit position of the bottom line that bottom line outlet test section comes out to the pin hole from described rotating shuttle towards described needle plate is in the right side or is in the left side with respect to the extended line that moves up and down track of described suture needle to be detected.In the directions X feeding amount that obtains by stitch data during less than described ormal weight, described control device determines to carry out according to the detected exit position of described bottom line outlet test section in the directions X of described ormal weight work feed+directions X or-directions X.
When the extended line that moves up and down track with respect to suture needle at bottom line was positioned at the right side, if upper thread leans against the right side of suture needle, then upper thread can not be wrapped in the suture needle.When the extended line that moves up and down track with respect to suture needle at bottom line was positioned at the left side, if upper thread leans against the left side of suture needle, then upper thread can not be wrapped in the suture needle.
In the control device of the Sewing machines of the Sewing machines of technical scheme 6 and technical scheme 12, with the feeding amount that on the basis of the directions X feeding amount that obtains by stitch data, increased virtual feeding amount towards described determined+directions X or-directions X carries out work feed.After this, the control device of Sewing machines and Sewing machines is with described virtual feeding amount work feed in the opposite direction.
When being " roughly zero " in directions X feeding amount, upper thread with respect to suture needle towards about not clear.At first on the direction of determining according to the detected exit position of bottom line outlet test section, carry out work feed with virtual feeding amount (unnecessary work feed).After this, the control device of Sewing machines is along Y direction work feed.Thus, can prevent that upper thread is wrapped in the suture needle.After this, in order to eliminate the virtual feeding amount (unnecessary work feed) of directions X, the control device of Sewing machines before work feed finishes with the reverse feeding of virtual feeding amount.

Main axis rotation angle detecting sensor 40 detects the anglec of rotation of main shaft 13.Main axis rotation angle detecting sensor 40 for example is made of rotary encoder.
Store in advance in ROM37: the distinctive work feed control program of various control programs, the application described later and being used to of control Sewing machines 1 is made a plurality of stitch datas of a plurality of patterns etc.ROM37 also stores speed feeding scale shown in Figure 8.But the cloth feed amount of the Y direction under the rotating speed that speed feeding scale makes motor of sewing machine 42 and this rotating speed is corresponding.ROM37 is equivalent to the application's storing mechanism.
In RAM38, suitably be provided with zone, counter zone of the operation result that interim storage CPU36 computing obtains etc.
The work feed control of control device 35 being carried out with reference to the flow chart of Fig. 9 describes.Wherein, the symbol Si (i=11,12,13 among the figure ...) be each step.
When beginning control shown in Figure 9 (beginning), control device 35 at first standby is made sign on (S11: not) to starting shutdown switch 24 outputs.If the operator selects to want the pattern made and carries out start-up operation (S11: be) to starting shutdown switch 24, then control device 35 is changed to initial value " 1 " (S12) with the count value N of stitching counter, read in (making) data of the stitching numbering of this stitching count value N indication, the directions X feeding amount XD of union data and Y direction feeding amount YD (S13).
When the directions X work feed reaches the small feeding amount of regulation (S18: be), control device 35 beginning Y direction feedings (S19).After this, control device 35 carries out the Y direction work feed of Y direction feeding amount YD and the directions X work feed of directions X feeding amount XD remainder simultaneously.When the Y direction work feed of the directions X work feed of directions X feeding amount XD and Y direction feeding amount YD finishes (S20: be), control device 35 judges whether stitching count value N is final stitching (S21).If stitching count value N is not that (S21: not), then control device 35 makes stitching count value N add 1 (S22) to final stitching (in making), carries out S13 step afterwards repeatedly.If stitching count value N is final stitching (S21: be), then control device 35 stops Sewing machines 1, makes to handle to get back to S11.
In S14, (S14: not), but then the rotating speed of 35 pairs of motor of sewing machine 42 of control device slows down to enlarge the time (S23) of work feed if control device 35 is judged as the Y direction work feed of the feeding amount of the small feeding amount of regulation that can not carry out having increased directions X on the basis of Y direction feeding amount YD.The part of the treatment S 23 of control device 35 is equivalent to the application's deceleration instruction portion.
(S15: not), control device 35 detects bottom line exit position (S24) according to the signal of bottom line outlet configuration switch 34 when directions X feeding amount XD is equal to or less than regulation feeding amount (being roughly 0.5mm).Then, set virtual positive negative direction (+directions X or-directions X) of carrying out work feed along directions X (S25) according to the testing result of bottom line exit position (dummy).And, to the upper thread UT that extends towards the place ahead from the pinprick 18a of suture needle 18 setting with respect to the directions X of suture needle 18 towards (+directions X or-directions X).Even not set the purpose of this virtual directions X work feed and be in order not produce during for " zero " or " roughly zero " yet and add the coiling mark at directions X feeding amount XD.
Bottom line DT when bottom line outlet opening 28a comes out (with reference to Fig. 3, Fig. 5) utilizing bottom line outlet configuration switch 34 to set so that need make upper thread UT lean against the left side of suture needle 18.At this moment, because the bottom line outlet of the bottom line DT that extends from vertical rotating shuttle 25 is in the left side with respect to the extended line N that moves up and down track of suture needle 18, therefore as virtual directions X feeding, control device 35 is set " left side :-directions X " forcibly for.
Bottom line DT when bottom line outlet opening 28b comes out (with reference to Fig. 6) utilizing bottom line outlet configuration switch 34 to set so that need make upper thread UT lean against the right side of suture needle 18.At this moment, because the bottom line outlet of the bottom line DT that extends from vertical rotating shuttle 25 is in the right side with respect to the extended line N that moves up and down track of suture needle 18, therefore as virtual directions X feeding, control device 35 is set " right side :+directions X " forcibly for.
The positive negative direction that control device 35 is set in the S25 with the directions X feeding amount XD that is equal to or less than regulation feeding amount and virtual feeding amount DD (for example being roughly 0.5mm) (+directions X or-directions X) is carried out work feed (S26).After this, control device 35 carries out the Y direction feeding (S27) of Y direction feeding amount YD.Control device 35 is carried out S20 step afterwards with the virtual reverse feeding of feeding amount DD (S28) of unnecessary work feed.
The part of S14 in the execution work feed control (Fig. 9) of control device 35 is equivalent to the work feed judging part.The data (Fig. 8) that are stored in the speed feeding scale in the ROM37 are equivalent to speed feeding amount information.The part of S24 in the execution work feed control of control device 35 is equivalent to bottom line outlet test section.
Action and effect to work feed control describes below.
Among Figure 10, when the front end of suture needle 18 was positioned at the extreme higher position, the phase angle of main shaft 13 was 0 °.But control device 35 judges whether can be in the feeding time to stipulate that to have increased directions X on the basis of Y direction feeding amount YD the feeding amount of small feeding amount carries out Y direction work feed according to the set information of the rotating speed of motor of sewing machine 42 and speed feeding scale shown in Figure 8.For example describe for the situation of " 2mm " for " 2mm ", Y direction feeding amount YD at the directions X feeding amount XD that forms the next stitching Na of current stitching N0 (as shown in figure 11) back formation being used for.The small feeding amount of the regulation of directions X is " 0.5mm ".
As shown in Figure 8, when the rotating speed of motor of sewing machine 42 is 3000rpm, but the cloth feed amount of maximum Y direction is 2.9mm.When the rotating speed of motor of sewing machine 42 is 2900rpm, but the cloth feed amount of maximum Y direction is 3.9mm.As shown in Figure 8, when Y direction cloth feed amount is equal to or greater than 4mm, need be equal to or less than the rotating speed of 2800rpm.The feeding amount of above-mentioned Y direction can realize during for 3000rpm at rotating speed for the work feed of " 2mm+0.5mm=2.5mm ".
When but the front end of suture needle 18 moved to time started of feeding time of needle plate 7 upsides, control device 35 court-directions X at first earlier carried out work feed to stipulate small feeding amount (0.5mm).In the moment that the work feed of the small feeding amount of the regulation of this court-directions X finishes, the work feed of beginning court-Y direction.After this, the remaining feeding amount court-directions X of " 1.5mm " that control device 35 obtains after with the small feeding amount of regulation that has deducted " 0.5mm " from directions X feeding amount XD carries out work feed, carries out work feed with the Y direction feeding amount YD court-Y direction of " 2mm ".
As shown in figure 11, because control device 35 is at first to stipulate that small feeding amount (0.5mm) carries out work feed to-directions X, therefore suture needle 18 this moment is corresponding with point " N0x " on the X-axis that has moved 0.5mm from needle downing position N0 court+directions X.At this moment, as shown in figure 12, the upper thread UT that passes the pinprick 18a of suture needle 18 from the rear towards the place ahead can not be wrapped in the suture needle 18, but towards the direction of previous stitching N0, be that left extends.Control device 35 carries out the work feed of the remainder of court-directions X from this moment, and carries out the work feed of court-Y direction.Consequently, as Figure 11, shown in Figure 12, suture needle 18 is positioned on the next stitching Na.At this moment, upper thread UT can not be wrapped in the suture needle 18, but goes towards previous needle downing position N0.
Below to directions X feeding amount XD near " 0.2mm " of " roughly zero ", can't realize that the situation of stipulating small feeding amount (0.5mm) describes with the work feed of initial directions X.Control device 35 (is roughly-0.7mm) court-directions X work feed with the small feeding amount that increased virtual feeding amount DD (for example being 0.5mm) on the basis of directions X feeding amount XD according to the signal of bottom line outlet configuration switch 34.Consequently, even directions X feeding amount XD is " roughly zero ", also can with upper thread UT with respect to suture needle 18 towards set for do not produce the expectation that adds the mark that winds the line towards.But, in order to eliminate the virtual unnecessary work feed of directions X, control device 35 before work feed finishes with the reverse feeding of virtual feeding amount DD.
Below the change form that has changed described embodiment is partly described.
1) when respectively making the work feed of action (each pin), at first the small feeding amount of regulation of carrying out work feed along directions X is set the roughly 0.5mm that drives X-axis CD-ROM drive motor 45 with ten pulses for, but can set feeding amount arbitrarily for according to the thickness of thickness, kind or the suture needle 18 of upper thread UT.
2) when respectively making the work feed of action (each pin), but towards the work feed time started of directions X be the zero hour of work feed time.
When little and directions X feeding amount XD is greater than Y direction feeding amount YD in the cloth feed amount of directions X and Y direction, also can make the work feed time started as follows.
Can be set for extreme higher position in suture needle 18 (main shaft 13 0 °) the feeding time started and finish the feeding of directions X feeding amount XD and Y direction feeding amount YD half (XD/2, YD/2) separately.At this moment, because directions X feeding amount XD greater than Y direction feeding amount YD, therefore begins the feeding of directions X earlier.
3) also can behind the work feed that has carried out whole directions X feeding amount XD, begin the work feed of Y direction.At this moment, but need finish the work feed of directions X and the work feed of Y direction in the time at work feed.
4) in the present embodiment, utilize two bottom line outlet opening 28a, 28b being located on the shuttle sleeve 28 to switch the bottom line exit position.Control device 35 utilizes bottom line exit position configuration switch 34 to discern the bottom line exit position.Also can replace this mechanism as follows.
