Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Example one
As shown in fig. 1, the method for controlling the bottom line allowance of the long seam line comprises the following steps:
s1, when the bottom line allowance insufficiency signal is received, judging whether the current suture line is a long suture line, if so, executing a step S2; if not, the sewing is continued to finish the thread cutting after the current thread is sewn, and the shuttle peg is replaced by stopping the sewing machine;
wherein, the long suture is the suture with the length of the bottom line to be consumed being X and X being more than M, and M is the remaining length of the bottom line, as shown in figure 2.
The bobbin thread margin length M can be preset and can be guaranteed to be a fixed length value, and the specific implementation can be realized by the technical scheme that a section of reserved length L of the bobbin thread is wound on the bobbin along one direction, then the bobbin thread is folded back, and the bobbin thread is continuously wound on the bobbin along the opposite direction until the bobbin is fully wound, as disclosed in the monitoring method and the monitoring device with the patent name of the bobbin thread margin for the sewing machine with the publication number of CN 109706646A. The length of each suture can be automatically known by the system through the pattern diagram of the template, and then the length is compared with the set margin length M of the bottom thread to judge whether the current suture is a long suture. The bottom line margin may be detected by other detection techniques, such as by a photo sensor, which will not be described in detail herein, and a bottom line margin deficiency signal may be provided when a margin deficiency is detected. If the current sewing thread is judged not to be the long sewing thread, the allowance of the bottom thread is enough to finish sewing the current sewing thread, so that the system does not need to do special treatment, the machine is stopped when the current sewing thread is finished, and the shuttle peg is replaced.
S2, if the suture is determined to be a long suture, identifying all virtual trimming points N1 and N2 … Nn on the current suture, virtually dividing the current suture into M segments by the virtual trimming points N1 and N2 … Nn, and calculating the lengths of the segments as Y1 and Y2 … Ym, wherein M is N +1, and Y1 and Y2 … Ym are both less than M, as shown in fig. 3;
the virtual thread trimming points N1 and N2 … Nn are respectively arranged at the positions of the current thread convenient to trim; the starting point and the end point of the current suture are respectively A and B, Y1 corresponds to the distance from the point A to the virtual trimming point N1, Y2 corresponds to the distance from N1 to N2, and so on, Ym corresponds to the distance from Nn to the point B, as shown in FIG. 3.
The virtual trimming points N1 and N2 … Nn are only added on the long stitches, and are edited on the template pattern drawing by a computer when the template pattern drawing is manufactured in advance, because the situation that the margin of the bottom stitches is not enough to completely sew the long stitches can occur only on the long stitches, and the length of the short stitches is less than the margin length of the bottom stitches, the situation that the bottom stitches are not enough to completely sew the short stitches can not occur after the margin shortage signal is received, and therefore, the virtual trimming points are only needed to be edited on the long stitches when the template pattern drawing is manufactured. The positions convenient for trimming are specifically corner positions in a template pattern drawing or positions capable of being covered by other fabrics and the like, namely the positions on the current sewing line which does not affect the attractiveness of the fabrics are the positions which do not appear too much on the appearance of the sewing line after trimming wiring processing is carried out on the virtual trimming points, the wiring is not obvious, and the attractiveness of the sewing line is not affected too much. The purpose of adding the virtual trimming point is to perform trimming wiring on the bottom line at a designated place, and the phenomenon that the wiring is performed at the place when the unordered bottom line is used up is avoided, so that the seam is not attractive easily.
The specific calculation method for the lengths of the sections Y1 and Y2 … Ym respectively comprises the following steps: defining the starting point A of the current suture line as an X-axis origin, AB as an X-axis direction, and after all virtual trimming points N1 and N2 … Nn are edited, each virtual trimming point corresponds to a determined X value, and then calculating Y1 and Y2 … Ym values according to the X values.
S3, detecting and calculating the current position C of the needle, and calculating the distance from the current position C to the starting point A to be Z, as shown in figure 3, if Z + M is larger than X, finishing thread cutting after finishing sewing the current thread, and stopping to replace the bobbin; otherwise, calculating to obtain an x value through a formula Y1+ Y2+ … + Yx which is not less than Z + M which is less than Y1+ Y2+ … + Y (x +1), and controlling to finish thread cutting and stop the machine to replace the shuttle peg when the sewing is continued to the virtual thread cutting point Nx;
wherein, the current position C is the current position of the needle on the current suture line when the bottom line allowance insufficiency signal is received; x is more than or equal to 1 and less than or equal to n. The specific detection calculation method of the current position C of the machine needle comprises the following steps: according to the number of sewing machine needles accumulated between the starting point A of the current sewing line and the time when the insufficient bottom line allowance signal is received, calculating an X value on an X axis formed by the AB at the moment by combining the needle pitch of each needle, and obtaining a current position C; and calculating the Z value by combining the starting point A.
The method comprises the following specific steps:
when Z + M is larger than X, the allowance of the bottom thread is enough to finish sewing the current thread, so that the thread is only required to be normally sewn and cut. Otherwise, the margin of the bottom thread is not enough to sew the current thread, and the thread is required to be cut at a proper virtual thread cutting point so as to avoid the phenomenon that the thread is not beautiful due to disordered thread cutting.
For example, when Y1 is less than or equal to Z + M is less than Y1+ Y2, which indicates that the bottom thread allowance can be used up between the virtual thread cutting points N1 and N2, the sewing is controlled to cut thread at the virtual thread cutting point N1 and the bobbin is replaced; when Y1+ Y2 is more than or equal to Z + M and less than Y1+ Y2+ Y3, the bobbin thread residual quantity is used up between the virtual thread cutting points N2 and N3, the sewing is controlled to cut thread at the virtual thread cutting point N2 and the shuttle peg is replaced; and by analogy, when Y1+ Y2+ … + Yn is less than or equal to Z + M and less than Y1+ Y2+ … + Y (n +1), indicating that the bottom thread allowance can be used up between the virtual thread cutting point Nn and the termination point B, controlling the sewing to cut the thread at the virtual thread cutting point Nn and replacing the shuttle peg. According to the Y1+ Y2+ … + Yx is less than or equal to Z + M and less than Y1+ Y2+ … + Y (x +1), the specific virtual trimming point is controlled to perform trimming, so that the beneficial effects that the bottom line is trimmed at the set virtual trimming point to avoid disordered trimming to cause unattractive sewing are achieved, the bottom line can be used up as far as possible on the basis of ensuring the beneficial effects, the bottom line is efficiently utilized, and the cost is reduced.
