[0039] Please see Figures 1-9 In this embodiment of the present invention, an automatic shoelace feeding and threading device for shoelace threading includes: a workbench 7 and a processing group disposed on the workbench 7; the processing group includes, in sequence: a feeding device 1, a discharging device 3, a threading device 5, and a transfer device 4 extending from the shoe upper feeding device 1 to the threading device 5.
[0040] In actual processing, multiple independent processing groups can be set up on the workbench 7 to improve overall processing efficiency;
[0041] The shifting device 4 is equipped with a clamping fixture 2. During processing, the manual cooperating with the feeding device 1 clamps the shoe upper and shoelaces into the clamping fixture 2. Then, the shifting device 4 sequentially feeds the clamping fixture 2 into the lacing device 5, and the lacing device 5 completes the shoelace lacing process of the shoe upper in the clamping fixture 2. Afterward, the shifting device 4 moves the clamping fixture 2 to the unloading device 3, and the unloading device 3 performs the unloading process of the shoe upper in the clamping fixture 2.
[0042] Furthermore, the clamping fixture 2 includes: a fixture base 23 and a shoe upper clamping assembly 21 and a shoelace clamping assembly 22 mounted on the fixture base 23;
[0043] The shoe upper clamping assembly 21 includes: a jig middle plate 216 disposed in the middle of the jig base 23, a pair of fixed clamping plates 215 installed on both sides of the jig middle plate 216, and a pair of movable clamping plates 213 disposed on both sides of the jig middle plate 216.
[0044] The bottom of the movable clamping plate 213 is hinged to the fixture base 23, and a clamping cylinder 211 is also provided in the middle of the fixture base 23. An opening and closing connecting frame 212 is provided between the clamping cylinder 211 and the movable clamping plates 213 on both sides.
[0045] During processing, the shoe upper is put on the shoe upper clamping assembly 21. The two shoelace perforation surfaces of the shoe upper are located between the movable clamping plate 213 and the fixed clamping plate 215. The clamping cylinder 211 drives the movable clamping plate 213 to flip up along the hinge position and cooperate with the fixed clamping plate 215 to realize the clamping action of the shoe upper.
[0046] Furthermore, both the fixed clamping plate 215 and the movable clamping plate 213 are provided with several U-shaped clearance slots 214, which correspond one-to-one with the shoelace holes on the shoe upper. When the shoe upper is clamped, the clearance slots 214 enable the fixed clamping plate 215 and the movable clamping plate 213 to clamp the entire shoe upper while exposing the shoelace holes, making it convenient to thread the shoelaces.
[0047] The shoelace clamping assembly 22 is located at the front end of the shoe upper clamping assembly 21, and includes: a shoelace fixing clamp 221 fixedly installed on the jig base 23, a shoelace movable clamp 222 movably installed on the jig base 23, and a clamping moving module 223 that drives the shoelace movable clamp 222 to move back and forth; during processing, the clamping moving module 223 drives the shoelace movable clamp 222 to cooperate with the shoelace fixing clamp 221, which can realize the clamping of the rope at both ends of the shoelace.
[0048] Furthermore, the opening and closing frame 212 includes: an opening and closing center seat 212a mounted on the clamping cylinder 211, and opening and closing connecting rods 212b extending to the movable clamping plates 213 on both sides at both ends of the opening and closing center seat 212a; the two ends of the opening and closing connecting rods 212b are respectively hinged to the opening and closing center seat 212a and the movable clamping plates 213.
[0049] When clamping the shoe upper, the clamping cylinder 211 drives the opening and closing center seat 212a to rise, and the opening and closing connecting rod 212b brings the two sets of movable clamping plates 213 together towards the center, which, together with the fixed clamping plate 215, realizes the clamping action of the shoe upper.
[0050] Furthermore, the feeding device 1 includes: a shoe upper feeding unit 11 for feeding shoe uppers and a shoelace feeding unit 12 for feeding shoelaces;
[0051] The shoe upper feeding unit 11 includes: a shoe upper feeding assembly 11B and a shoe upper pulling assembly 11A;
[0052] The shoe upper placement assembly 11B includes: a pair of shoe upper placement Z-axis cylinders 117 arranged parallel to each other on both sides of the traveling processing direction of the transfer device 4; a shoe upper placement X-axis cylinder 114 that moves toward the center position is mounted on the shoe upper placement Z-axis cylinder 117; a positioning seat 115 arranged parallel to the fixed clamping plate 215 is mounted on the shoe upper X-axis cylinder 114; and a plurality of positioning pin rods 116 extending toward the center are provided on the positioning seat 115; the positioning pin rods 116 can be inserted into the shoelace holes of the shoe upper.
[0053] The shoe upper assembly 11A includes: a shoe upper Y-axis cylinder 113 located at the upper end of the traveling processing direction of the shifting device 4, and a shoe upper Z-axis cylinder 111 located at the very upper end of the traveling processing direction of the shifting device 4. The shoe upper Z-axis cylinder 111 is connected to the shoe upper Y-axis cylinder 113 via a connecting frame; and a set of shoe upper guide wheels 112 are provided on the shoe upper Z-axis cylinder 111.
[0054] During the shoe upper clamping process, the shoe upper pulling assembly 11A and the shoe upper releasing assembly 11B perform corresponding processing actions respectively:
[0055] Among them, the upper-pulling assembly 11A works by driving the upper-pulling guide wheel 112 down to between the two shoelace perforation surfaces of the upper through the upper Z-axis cylinder 111. Then, the upper-pulling Y-axis cylinder 113 drives the upper-pulling guide wheel 112 to move along the upper. The loading personnel and the upper-pulling guide wheel 112 apply force to both sides to straighten the upper.
[0056] The upper placement assembly 11B operates by using the Z-axis cylinder 117 to move the positioning pin 116 down to a specific height. Then, the X-axis cylinder 114 moves the positioning pin 116 towards the center. The loading personnel adjust the height of the upper to ensure the positioning pin 116 can smoothly pass through the shoelace holes, thus achieving the positioning of the upper installation. Finally, the clamping fixture 2 clamps the upper, completing the clamping process for the entire upper loading process.
[0057] The shoelace feeding unit 12 includes: a belt-pulling cylinder 122 located at the lower end of the traveling processing direction of the frame-shifting device 4. The belt-pulling cylinder 122 moves vertically upward, and a belt-pulling plate 121 is installed on the shoelace-pulling cylinder.
[0058] When the shifting device 4 moves the clamping fixture 2 toward the lacing device 5, the pulling cylinder 122 drives the pulling plate 121 to rise and hook the shoelace. During the continuous movement of the shifting device 4 and the clamping fixture 2, since the main body of the shoelace is soft, it is impossible to clamp the shoelace itself when the shoelace movable clamp 222 and the shoelace fixed clamp 221 are engaged. This achieves the effect of pulling the shoelace out from the clamping position of the shoelace movable clamp 222 and the shoelace fixed clamp 221 until the rope of the shoelace enters the clamping position, thus completing the pulling work. This processing method can realize the automatic fixed-length work of shoelace feeding (making the two ends of the shoelace the same length), effectively improving the work efficiency of shoelace feeding.
[0059] Furthermore, the moving device 4 includes: a set of moving modules 41, a lifting module 43 mounted on the moving modules 41, and a clamping fixture 2 mounted on the lifting module 43 (the lifting module 43 is provided with a mounting base 42);
[0060] The shifting module 41 extends from the loading position of the loading device 1 to the processing position of the wiring device 5. During operation, the shifting module 41 and the lifting module 43 work together to drive the clamping fixture 2 to cooperate with the loading device 1, the unloading device 3 and the wiring device 5 respectively to achieve processing cooperation.
[0061] Furthermore, the cable-tying device 5 comprises: a unit frame 51 and a cable-tying unit 53 and a cable-pressing unit 52 mounted on the unit frame 51;
[0062] The cable tie unit 53 includes two sets of parallel cable tie groups 531 and a transfer cable group 532 disposed between the cable tie groups 531;
[0063] The cable pulling assembly 531 includes a set of transverse cable pulling cylinders 312 mounted on the unit frame 51 and cable pulling claws 311 horizontally mounted on the piston seat of the transverse cable pulling cylinders 312;
[0064] The cable transfer assembly 532 includes a cable transfer base 322 mounted on the unit frame 51 and a cable transfer module 321 for driving the cable transfer base 322 to rotate. The cable transfer base 322 is equipped with a pair of vertically arranged cable transfer claws 324 and a cable transfer cylinder 323 for driving the two sets of cable transfer claws 324 to move to both sides.
[0065] The wire pressing unit 52 in the wire-binding unit 53 includes a wire pressing lifting module 521 and two wire pressing uprights 522 mounted on the unit frame 51. The wire pressing uprights 522 are slidably engaged with the unit frame 51, and the lower end of the wire pressing uprights 522 is provided with a wire pressing clamping cylinder 523 for realizing wire clamping work.
[0066] During processing, the shoelace ends are clamped by the thread-turning claw 324 and taken from the clamping fixture 2. Then, the moving frame module 41 continues to move forward to align the thread-turning claw 324 with the shoelace hole, with the thread-turning claw 324 positioned in the middle of the two shoe uppers. Then, the thread-turning moving cylinder 323 drives the two thread-turning claws 324 to open to both sides, allowing the end of the shoelace to pass from the inside of the shoelace hole to the outside. Then, the horizontal thread-pulling cylinder 312 drives the thread-pulling claw 311 forward to pull the end of the shoelace that has passed through the shoelace hole. Then, the horizontal thread-pulling cylinder 312 moves backward to realize the thread-pulling action. Then, the thread-pressing lifting module 521 drives the thread-pressing clamping cylinder 523 downward to clamp the shoelace. Then, the thread-pressing lifting module 521 drives the thread-pressing clamping cylinder 523 to continue downward to pull the entire shoelace out of the shoe upper, completing the first thread-tying process.
[0067] Then, two rotating clamps 324 grab the shoelace cord from the pull clamp 311 again. Then, the rotating cylinder 323 drives the rotating clamps 324 to converge towards the center and move to the middle position of the two shoe uppers. Then, the fixture moves forward one working position so that the rotating clamps 324 are aligned with the next shoelace hole. Then, the rotating module 321 drives the rotating clamps 324 to rotate 324 at 30°, so that the two shoelaces are crossed (cross-lacing method). Then, the above shoelace lacing work is repeated to complete the shoelace processing work.
[0068] Furthermore, the unloading device 3 includes: an unloading bracket, an unloading transverse moving module 31 mounted on the unloading bracket, and an unloading lifting module 32 mounted on the unloading transverse moving module 31;
[0069] The unloading lifting module 32 is equipped with a set of unloading and picking claws 34 for clamping and picking up materials, a heel pressure plate 35 for pressing down the heel position of the shoe upper, and a pressure plate cylinder 33 for driving the heel pressure plate 35 to descend.
