In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
Fig. 1 and Fig. 2 are please referred to, a kind of sewing control method S100 of sewing machine provided in an embodiment of the present invention is suitable for
Sewing has the tubular clothing of foldable layer 200, and the sewing control method S100 of the sewing machine includes: sewing needle assemblies to rotation
Foldable layer 200 sew, be used to arrange the outer of foldable layer 200 in the pinch roller of the side setting rotation of the sewing needle assemblies
The pinch roller is arranged if the perimeter M of the outer layer 202 of foldable layer 200 is greater than the perimeter S of the inner layer 201 of foldable layer in layer 202
Revolving speed is higher than the revolving speed of the foldable layer.Wherein, the tubular clothing refers to that the cross section of clothing is annular in shape, common
There are the ring waist portions of underpants, the trouser legs of trousers, bottom of T-shirt etc., in the present embodiment by taking the ring waist portions of underpants as an example；Described
Foldable layer is specifically the tubular clothing stepped construction that its end fold inward is formed when carrying out sewing processing；The outer layer week
Long length of the outer layer along its circumferencial direction for referring to foldable layer.
It is further elaborated in conjunction with Fig. 2, Fig. 2 is the unfolded state schematic diagram of foldable layer 200, foldable layer 200
The perimeter M of outer layer 202 has more length L than the perimeter S of inner layer 201, and the revolving speed by the way that pinch roller is arranged is higher than turning for foldable layer 200
Speed, pinch roller can sew needle assemblies doubling lamination 200 sewed during by outer layer 202 relative to inner layer 201 toward folding
The rotation direction of lamination 200 is stirred, in this way, sewing one needle of needle assemblies sewing every to inner layer 201, so that it may incorporate some outer layers more
202, for the outer layer after sewing as shown in 202', fold is uniform, and sewing quality is high.If the revolving speed for being not provided with pinch roller is higher than foldable layer
200 revolving speed, flat, the partial folds serious situation that is easy to appear foldable layer part of foldable layer 200 after sewing.
Referring to Fig. 3, mode as an improvement of this embodiment, if the inner layer 201 and 202 stress of the outer layer are drawn
It pulls, the deformation quantity of the outer layer 202 is less than the deformation quantity of the internal layer 201, then the revolving speed of the pinch roller is arranged lower than the folding
The revolving speed of lamination 200.
In the practical sewing process of reality, it can usually find that clothing to be sewed moves towards different due to lines, lead to clothing
The deformation quantity generated when stress is pullled is different, and on the basis of direction of travel when being sewed by clothing, usually the lines of clothing is in cross
When line (parallel with the direction of travel of clothing) or vertical line (vertical with the direction of travel of clothing), clothing stress pulls the shape of generation
Variable is smaller, and when the lines of clothing is in twill (being in angle with the direction of travel of clothing), clothing stress pulls the deformation of generation
It measures larger.Specifically by taking underpants as an example, the preceding width of underpants there is a variety of different lines, and each section lines stress pulls generation
Deformation quantity is different.
In the present embodiment, if inner layer 201 and 202 stress of outer layer are pullled, the deformation quantity of outer layer 202 is less than internal layer 201
When deformation quantity, the revolving speed by the way that pinch roller is arranged is lower than the revolving speed of foldable layer 200, and pinch roller can stir outer layer 202, so that outer layer
202 deformation quantity is consistent with the deformation quantity of internal layer 201, in this way, outer layer 202 and internal layer 201 are sewed after sewing will not a little occur

It is further described in detail in conjunction with Fig. 3, the unfolded state of foldable layer 300 shown in Fig. 3, due to outer layer 202
Deformation quantity be less than inner layer 201 deformation quantity, after 200 stress of foldable layer struts, the length of inner layer 201 is extended for D+D' by D, outside
The length of layer 202 becomes H+H', D'> H' from H.For inner layer 201, after strutting, B point is moved to B1 point, for outer layer
For 202, C point is moved to C1 point, if inner layer 201 is consistent with the deformation quantity of outer layer 202, C1 point should be sutured with B1 point, now
Since the deformation quantity of outer layer 202 is less than the deformation quantity of inner layer 201, lead to C1 point and the suture of B2 point namely inner layer 201 and outer layer
202 sewing point is misplaced, in this way, after external force revocation, inner layer 201 and outer layer 202 are multiple when the sewing of foldable layer 200 terminates
Position, outer layer 202 and internal layer 201 are distorted, and cause fold to tilt, sewing quality is low.And by setting pinch roller, and pinch roller is set
Revolving speed be lower than foldable layer 200 revolving speed, in this way, pinch roller can by outer layer 202 toward 200 direction of travel of foldable layer reversely stir,
So that C1 point reaches B1 point, when the sewing of foldable layer 200 terminates, after external force revocation, inner layer 201 and outer layer 202 reset, outer layer 202
It will not be distorted with inner layer 201, fold not run-off the straight, sewing quality height.
