Fig. 2 is the flow chart that is used to illustrate following drive controlling, promptly, utilize the not shown control device for sewing-machine in the band sewing machine for sewing of present embodiment and the control module 19 of band material feeding apparatus 2, at one end portion is sewn to the other end of the band material T that makes on owner's body M, utilize forked parts 24 to form bending states or do not bend and under the state that extends, on making owner's body M, form the 3rd and reinforce seam S3 and when sewing up, as the drive controlling of the described X-axis driving pulse motor XPM and the Y-axis driving pulse motor YPM of mobile unit 15.
In addition, in the present embodiment, the shape of the band of formation is under the state that does not bend in the extension of the other end of band material T as shown in Figure 8, makes and is making on owner's body M.This shape of reinforcing seam as shown in figure 10, form straight line made and word make the stitching shape that the length and width size that combines is represented with x, y respectively, be used to form the moving range of the described presser feet of this stitching, illustrate with chain-dotted line among Fig. 3 to Fig. 5 below.In addition, in Fig. 3 to Fig. 5, the locational grip unit 13 that will be arranged in the state of clamping band material T is represented by dotted lines, and the grip unit 13 that will be positioned on the home described later is represented with solid line, in addition, the grip unit 13 that will be positioned on the initial position is represented with double dot dash line.
In the present embodiment, at first, judge whether the timing of decontroling for the clamping that makes band material T (ST1).
For example, band after making is for reinforcing under the situation of the shape of stitching S3 to form the 3rd under the state by the other end side of grip unit 13 clamping band material T, because regularly at this, formed the 3rd and reinforced seam S3, so become the timing (ST1 is for being) that initial position was decontroled and was back in the clamping that makes 13 pairs of band materials of grip unit T.In addition,, so presser feet 5 need in order to form reinforcing seam not move thus, can with grip unit 13 not interfere because making of band finished this moment.
Thus, control module 19 is removed after the clamping of band material T in that cylinder C2 is driven, X-axis driving pulse motor XPM is driven and make the grip unit 13 of having decontroled band material T on the width of band material T, retreat (ST2), be back to initial position and finish.
In addition, do not reinforce seam S3 rather than make under the situation of the timing that the clamping of band material T decontrols (ST1 for not) forming the 3rd as yet, afterwards, whether judge the shape of the band material T the other end side in the band of making that sets, be the shape (ST3) of not using forked parts 24 to form.
The shape of the other end side of the band material T in the band of making, for using forked parts 24 to be bent under the situation of shape of U word shape (ST3 for not), make after the other end bends, mobile unit 15 is retreated along X-direction, be back to initial position.Timing in the bending action end, in order from the band material T that reels, to extract the fork 24A of forked parts 24, need forked parts 24 be moved along directions X by mobile unit 15, but because forked parts 24 and grip unit 13 utilize mobile unit 15 to move together, so lasting mode that moves along directions X till grip unit 13 arrives initial position, with carry out the mobile phase ratio along the Y direction, can make grip unit 13 move to the position of leaving from the moving range of presser feet 5 with shorter required time.Specifically, driving by cylinder C5, make the direction of grip unit 13 from making the throughput direction quadrature of owner's body M when making, move to the transport path of making owner's body M, under the state of clamping band material T on the fork, make revolving actuator RA1 rotation, band material T is wound on the forked parts 24 and makes band material T be bent into U word shape.During this period, make the other end of band material T pass and decontrol from grip unit 13.Then, make X-axis driving pulse motor XPM driving and mobile unit 15 is moved along X-direction, forked parts 24 are extracted from the band material T that reels, simultaneously, make grip unit 13 that band material T is decontroled retreat (ST2), be back to initial position and finish along the width (X-direction) of band material T.In addition, on the other end of the band material T that bends, use known method to form the 3rd thereafter and reinforce seam S3.
In addition, the shape of the other end of the band material T in the band of making, be the band made in the present embodiment like this, do not use under the situation of shape of forked parts 24 (ST3 is for being), described grip unit 13 is kept out of the way from the moving range of the presser feet 5 corresponding with the geomery of the reinforcing seam that sets, on one side the method for selecting to be back to initial position is judged.
As described method, have two kinds of methods: the X-direction back-off method, it only makes described X-axis driving pulse motor XPM drive, and mobile unit 15 is moved along X-direction, and grip unit 13 is kept out of the way along X-direction; And Y direction back-off method, it is in or the while more Zao than the driving of X-axis driving pulse motor XPM, described Y-axis driving pulse motor YPM is driven with described X-axis driving pulse motor XPM, mobile unit 15 is moved along Y direction, grip unit 13 is kept out of the way along Y direction.In the present embodiment, in described selection course, obtain and make grip unit 13 keep out of the way to required time of the home that leaves from the moving range of described presser feet 5 with beeline and compare in described two kinds of methods, control to select the shorter method of required time.
Specifically, in the X-direction back-off method, obtaining the grip unit 13 that makes clamping that band material T be arranged moves along X-direction, distance (coordinate figure) when moving to from position (X-direction home) that the moving range of the presser feet 5 corresponding with the geomery of the reinforcing that sets seam is left, move the required time with this, simultaneously, in the Y direction back-off method, obtaining the grip unit 13 that makes clamping that band material T be arranged moves along Y direction, distance (coordinate figure) when moving to from position (Y direction home) that the moving range of the presser feet 5 corresponding with the geomery of the reinforcing that sets seam is left, move the required time (ST4) with this, control and select the shorter method of required time (ST5).
As described selection, also can carry out following method, promptly, to in the X-direction back-off method, the displacement (coordinate figure) of clamping grip unit 13 that band material T arranged till the described X-direction home, with in the Y direction back-off method, the displacement (coordinate figure) of clamping grip unit 13 that band material T arranged till the described Y direction home compares, control to select the shorter method of displacement.But, because the speed of X-axis driving pulse motor XPM and Y-axis driving pulse motor YPM can change respectively, so under situation about merely only selecting according to displacement, existence can't reduce the possibility of the stand-by period when forming the reinforcing seam of the other end, therefore in the present embodiment, keep out of the way according to the mobile required time.

After this shift action is finished, X-axis driving pulse motor XPM is driven and mobile unit 15 is moved along X-direction, make the grip unit 13 that band material T is decontroled on the width (X-direction) of band material T, retreat to the X-axis coordinate identical with initial position.
Then, Y-axis driving pulse motor PM is driven and mobile unit 15 is moved along Y direction, advance (ST6) along the length direction (Y direction) of band material T, be back to initial position and finish by making grip unit 13.In addition, in Fig. 4, be illustrated in the track of the described grip unit 13 under the situation of carrying out this control by arrow.
In addition, as the drive controlling under the situation of having selected the Y direction back-off method, also can be as shown in Figure 5, by Y-axis driving pulse motor YPM being driven make mobile unit 15 to move along Y direction, simultaneously, make X-axis driving pulse motor XPM driving and mobile unit 15 is moved along X-direction, be about to before the width (X-direction) of band material T is gone up the arrival X-axis coordinate identical with initial position in grip unit 13, make Y-axis driving pulse motor YPM driving once more and mobile unit 15 is moved along Y direction, grip unit 13 is advanced (ST6) on the length direction (Y direction) of band material T, thereby be back to initial position and finish.In addition, in Fig. 5, be illustrated in the track of the described grip unit 13 under the situation of carrying out this control with arrow.
Under the situation of above-mentioned Y direction back-off method, the 3rd reinforces making of seam S3, can begin in the stage that the hold assembly 13 that retreats along Y direction is positioned at the Y-axis coordinate identical with the home of described Y direction, can make until the clamping of being undertaken by the grip unit 13 of band material T and decontrol and make the time shortening of reinforcing till stitching, make the operating efficiency raising.
In addition, the present invention is not limited to above-mentioned embodiment, can carry out various changes as required.
