Detailed ways

The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

Referring to Figure 1-8,

A shoe bag sewing device, comprising a frame 1, a sewing assembly 3 mounted on the frame 1 with a machine head 2 for sewing, a sewing mechanism arranged on the machine head 2, a sewing machine installed on the sewing assembly 3 Push-pull assembly 4 for pushing fabrics, also includes

The visual line drawing component 5 is installed on the frame 1, and the sewing track of the fabric is set through image recognition;

The edge back device 6 is arranged on the sewing mechanism and is used to adjust the sewing margin of the fabric;

When the rotating mechanism 7 drives the machine head 2 to rotate, the edge stopper 6 is kept perpendicular to the edge of the material.

In the above scheme, the frame 1 is mainly a platform for the sewing component 3 to work, and the visual line drawing component 5 is used to identify the fabric to be sewn, and the image is captured and processed, and the processed image is prefabricated. Trajectory coordinates, map the set sewing line, match the sewing line with the image, and then obtain the sewing track to be sewn on the current fabric, and pass the identified sewing track to the sewing component 3, and the sewing component 3 according to the track. fabric for sewing. Shoe bags are generally composed of two pieces of fabric, one of which corresponds to the toe cap and the other corresponds to the upper. The two need to form a three-dimensional structure when sewing. When matching the sewing trajectory, since the sewing trajectory of the two pieces of fabric is the same, so The length is also the same, but the length of the fabric corresponding to the upper is generally shorter, while the length of the corresponding toe cap is longer. At this time, the two need to be sewn, and the length of the toe cap will be compressed to the length of the slope. , so the toe cap will naturally form a three-dimensional structure, and the sewing track can be set through the visual line drawing component 5, so that the fabrics with different radians can be sewed together, and then the sewing of the three-dimensional structure can be realized, and more efficient automation can be realized. The specific line-drawing scheme can be adopted in the following way. On the material A, according to the parallel shrinkage of the edge by 1 mm, the corresponding length of the line is obtained. The X and Y coordinates of the point. The template sewing method used in the prior art can only be used for flat sewing. Of course, the prior art also has sewing for the toe cap of the shoe bag, but the sewing method in the prior art is to use three-dimensional clamps to align the shoes. The fabric of the head is shaped, and then stitched by plane sewing. This kind of stitching is inefficient and requires manual operation of fabric clamping. Since this solution still requires manual operation, most manufacturers still directly use manual sewing. This kind of sewing will have problems such as poor quality control, unattractive sewing effect, and low sewing efficiency.

Wherein, the setting of the edge back device 6 can keep the sewing margin consistent, making the sewing more beautiful. And the side rest 6 can cooperate with the rotation mechanism 7, utilize the rotation effect of the rotation mechanism 7, let the side rest 6 always abut against the edge of the fabric, and then keep the sewing distance consistent all the time, and the rotation mechanism 7 performs the rotation action according to the sewing track at the same time, so The turning mechanism 7 can rotate with the side rest 6 while rotating, so the side rest 6 can always abut against the edge of the fabric and maintain a vertical state, and then guide the sewing margin of the sewing assembly 3 to keep consistent, improving the appearance of sewing effect, and can make the sewing lines smoother.

Control; and visual line drawing component 5 is prior art, carries out image capturing by area array camera, and image is analyzed, preset trajectory is matched on image, after dividing coordinates, the trajectory of curve on coordinates can be obtained, The sewing of the trajectory can be completed through the coordinates.

Wherein, the rotating mechanism 7 includes a driving part 71 and a turntable 72, the needle bar 21 is arranged on the machine head 2, and the turntable 72 is coaxial with the needle bar 21 and is rotatably installed on the machine head 2, so The driving part 71 is installed on the machine head 2 and is linked with the turntable 72 to drive the turntable 72 to rotate; the edge stopper 6 and the push-pull assembly 4 are arranged on the turntable 72, and when the turntable 72 rotates, the side stopper 6 and the push-pull assembly 4 are arranged on the turntable 72. The push-pull assembly 4 rotates.

The driving part 71 can adopt a motor, and the motor can be a stepping motor or a servo motor; the motor can be linked with the turntable 72 through gears, and when the driving part 71 drives the turntable 72 to rotate back and forth, it can rotate with the edge stopper 6 and the pushing device , push by pushing foot 42 to ensure that the edge stopper 6 is kept perpendicular to the edge of the fabric. The direction of pushing can also be changed while rotating with the push-pull assembly 4, so that the lines sewn are smoother curves.

The push foot 42 also rotates up and down accordingly. By using this up and down rotation, the push foot 42 can cooperate with the presser foot 23. When the presser foot 23 moves downward, the push foot 42 moves downward to fit on the fabric. Among them, the pushing action of the push foot 42 is before the presser foot 23 touches the fabric downwards. At this time, the horizontal reciprocating mechanism 41 moves with the push foot 42, and then pushes the fabric, so that the next sewing point reaches the needle bar 21 below. This mode of cooperation can avoid the conflict between the pusher foot 42 and the presser foot 23, and utilize the longitudinal reciprocating mechanism 22 and the horizontal reciprocating mechanism 41 to carry out linkage. At this time, the work can be made more stable, ensuring that the cooperation between the presser foot 23 and the pusher foot 42 is more stable.
