[0043] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0044] like Figure 1 and Figure 2 As shown, an automatic shoelace threading device of the present embodiment includes a loading and positioning component 3 which is driven by a translation mechanism 2 to move horizontally in the Y direction, and a shoe upper 10 is fixedly clamped on the loading and positioning component 3; a belt pulling mechanism 9 and a belt inserting claw 8 are arranged in sequence above the loading and positioning component 3, and the belt inserting claw 8 is driven by a belt inserting moving mechanism 7 in combination with a belt inserting lifting mechanism 70 to move in the X direction and the Z direction; a belt connecting claw 5 is arranged below the loading and positioning component 3, and the belt connecting claw 5 is driven by a belt connecting moving mechanism 50 and a belt connecting lifting mechanism to move in the X direction and the Z direction; the belt inserting claw 8, the loading and positioning component 3, and the belt connecting claw 5 are arranged one by one from top to bottom.

[0045] In this embodiment, the Y direction corresponds to the spacing arrangement direction of the shoe holes on the upper 10, the X direction corresponds to the arrangement direction of the two rows of shoe holes on the upper 10, and the Z direction corresponds to the direction of tightening the shoelace 20 and threading it up and down.

[0046] In this embodiment, after the shoe upper 10 is fixed on the loading and positioning assembly 3, the upper strap insertion clamp 8 and the lower strap connection clamp 5 cooperate with each other and combine with the movement of the translation mechanism 2 to cross-thread the shoelaces 20 between the two rows of shoe holes, thereby realizing the automatic threading of the shoelaces 20 on the shoe upper 10 and effectively replacing manual work; the shoelace pulling mechanism 9 can also effectively ensure that the shoelaces 20 are smooth when being threaded.

[0047] The shoelace threading device in this embodiment can also be used for threading the shoelaces 20 on the upper 10 having three rows, four rows, etc. of shoe holes. Through the cooperation of the upper strap insertion clamp 8 and the lower strap connection clamp 5, the ends of the shoelaces 20 are threaded in order upward and downward in the shoe holes of the upper 10 according to the preset shoelace threading form and pattern.

[0048] In this embodiment, the strap insertion jaws 8 and the strap pulling mechanism 9 move up and down alternately. When the strap insertion jaws 8 move downward to insert the shoelace 20 head toward the vamp 10, the strap pulling mechanism 9 moves upward so as to slightly tighten and flatten the shoelace 20 upward, effectively preventing the shoelace 20 from being accidentally entangled or coiled. When the strap insertion jaws 8 clamp the shoelace 20 head and move up to tighten the shoelace 20, the strap pulling mechanism 9 can move downward to avoid the movement of the strap insertion jaws 8 and facilitate the next action of flattening the shoelace 20, thereby effectively ensuring the smooth and smooth process of threading the shoelace 20 and ensuring the stable and consistent threading of the shoelace 20.

[0049] The strap inserting jaws 8 and the strap connecting jaws 5 each include two corresponding ends of the shoelace 20. The two strap inserting jaws 8 constitute a group of two ends of the inserted shoelace 20, and the two strap connecting jaws 5 constitute a group of two ends of the inserted shoelace 20. Therefore, in the same step, the two strap inserting jaws 8 can insert the ends corresponding to the two ends of the shoelace 20 in turn, and at the same time, the two lower strap connecting jaws 5 can receive and insert the ends of the shoelace 20 in turn, thereby completing a cross-threading of the shoelace 20 and effectively improving the efficiency of shoelace threading.

[0050] Of course, in actual use, the two upper strap inserting jaws 8 can also form a group and cooperate with the single lower strap connecting jaw 5 to perform the shoelace threading operation; for example, after one end of the shoelace 20 is inserted downward by one of the upper strap inserting jaws 8, it is received by the strap connecting jaw 5 and passed back upward from the other shoe hole, and the same strap inserting jaw 8 clamps the end of the shoelace 20 just inserted upward from the top, and then the other strap inserting jaw 8 performs the same action, thereby completing a cross-threading of the shoelace 20; the threading of the shoelace 20 on the vamp 10 can also be achieved, but the threading speed is relatively slow.

[0051] The single belt inserting clamping jaw 8 and the single belt connecting clamping jaw 5 have the same structure, both of which include a clamping finger cylinder, and the output part of the clamping finger cylinder is equipped with clamping jaws that move towards or away from each other.

[0052] In this embodiment, the clamping jaws can be contoured according to the shape of the end of the shoelace 20 to effectively ensure that the clamping jaws can reliably clamp the end of the shoelace.

[0053] It also includes a vertically arranged frame 6, a belt-pulling mechanism 9 is installed on the middle part of the frame 6 via a belt-pulling lifting mechanism 98, and a belt-inserting moving mechanism 7 is installed on the upper part of the frame 6 via a belt-inserting lifting mechanism 70, so as to realize the independent up and down movement of the belt-pulling mechanism 9 and the belt-inserting moving mechanism 7.

[0054] In this embodiment, the belt-pulling lifting mechanism 98 and the belt-inserting lifting mechanism 70 can adopt existing conventional lifting mechanisms, such as linear driving power including air cylinders, oil cylinders, electric cylinders, etc., or a linear driving power composed of a motor through a lead screw and a screw pair, or other lifting mechanisms that can realize the up and down movement of the belt-pulling mechanism 9 and the belt-inserting mechanism 7.

[0055] One or more belt inserting claws 8 are installed on the side of the belt moving mechanism 7; a belt pulling rod 94 arranged axially along the X direction is installed in the belt pulling mechanism 9, and one or more belt pulling rods 94 are arranged corresponding to the belt inserting claws 8. A single belt pulling rod 94 moves along the X direction driven by the translation driving power 93.

[0056] In this embodiment, one group of strap insertion jaws 8 corresponds to threading the shoelace 20 on one shoe upper 10 , and multiple groups of strap insertion jaws 8 thread the shoelaces 20 on multiple shoe uppers 10 simultaneously and synchronously.

[0057] In this embodiment, one end of the lace-pulling rod 94 is mounted on the second translation driving power 93, and the other end of the lace-pulling rod 94 is passed under the shoelace 20 in combination with the movement in the X direction, so that the shoelace 20 can be pulled up and straightened by moving the lace-pulling rod 94 upward.

[0058] exist Figure 2 In the illustrated embodiment, the structure of the belt-pulling mechanism 9 is as follows: it includes a belt-pulling lifting seat 96 installed on a belt-pulling lifting mechanism 98, and the belt-pulling lifting seat 96 is installed on the side of the frame 6 for sliding up and down via a belt-pulling guide rail 97; supports 91 are installed at intervals at both ends of the belt-pulling lifting seat 96, and a single support 91 is installed with a translation driving power 1 92, and the output end of the translation driving power 1 92 is arranged toward the Y direction, and belt-pulling seats 95 are installed at the output ends of the translation driving power 1 92 on both sides, and translation driving power 2 93 is installed at intervals along the X direction on the belt-pulling seat 95, and a belt-pulling rod 94 is installed at the output part of the translation driving power 2 93.

[0059] In this embodiment, the translation driving power 1 92 drives the belt-pulling seat 95 and the belt-pulling rod 94 to move in the Y direction. When combined with the movement in the X direction, the belt-pulling rod 94 can hang and loosen the shoelace 20, and can also effectively avoid the upward and downward movement of the belt-inserting clamp 8.

[0060] like Figure 3As shown, the structure of the tape insertion moving mechanism 7 is as follows: it includes a tape insertion lifting seat 71 installed on the tape insertion lifting mechanism 70, a support plate 74 is installed on the side of the tape insertion lifting seat 71, and tape insertion translation forces 73 are installed at intervals on the upper and lower inner sides of the support plate 74, and tape insertion translation blocks 72 are respectively installed on the output parts of the single tape insertion translation forces 73, and the tape insertion translation blocks 72 pass forward through the support plate 74 and are then installed with tape insertion seats 76; two tape insertion seats 76 are slidably installed on the front side of the support plate 74 along the X direction via the tape insertion translation guide rail 75, and tape insertion claws 8 are respectively installed on the sides of the single tape insertion seats 76.

[0061] In this embodiment, two tape insertion translation forces 73 drive two of the same group of tape insertion jaws 8 through the tape insertion translation block 72 and the tape insertion seat 76, respectively, to achieve independent movement of the two tape insertion jaws 8 in the same group in the X direction; at the same time, multiple groups of tape insertion jaws 8 can be synchronously moved under the same power, achieving the efficiency of one driving three.

[0062] like Figure 5 As shown, the structure of the loading and positioning component 3 is as follows: it includes a translation seat 23 installed on the translation mechanism 2, a supporting part for supporting the upper 10 is installed on the translation seat 23, and quick pressing heads 31 are symmetrically installed on the translation seats 23 located on both sides of the supporting part, and a pressing block 32 is installed on the output part of the quick pressing head 31; the upper 10 is laid flat on the supporting part, and the pressing blocks 32 are pressed on both sides of the upper 10; a vertical seat 33 is also installed on the side of the translation seat 23, and a shoelace 20 is hung on the vertical seat 33, and a socket 331 for inserting the ends of the shoelace 20 is opened at the top of the vertical seat 33; thereby, the upper 10 and the shoelace 20 on the loading and positioning component 3 are simultaneously loaded and clamped, which is convenient for automatically threading the shoelace 20 on the upper 10 after loading.

[0063] In this embodiment, an intermediate wheel 36 is rotatably installed on the back of the vertical seat 33, and vertical long grooves 332 are symmetrically opened on the vertical seat 33 located on both sides of the intermediate wheel 36, and the self-weight wheels 34 are slidably installed in the vertical long grooves 332 respectively; a wedge block 35 is also installed on the vertical seat 33 located above the intermediate wheel 36, and the bottom surface of the wedge block 35 facing the intermediate wheel 36 is set as an upward inclined surface.

[0064] When loading, the self-weight wheel 34 is located at the bottom end of the vertical long groove 332 under the action of its own weight. At this time, the self-weight wheel 34 is lower than the intermediate wheel 36; the middle part of the shoelace 20 is hung above the intermediate wheel 36, and the two ends of the shoelace 20 are respectively wrapped downwardly under the self-weight wheel 34, and then the two ends of the shoelace 20 are moved up and the bundle ends are inserted into the plug holes 331 at the top of the vertical seat 33; after the bundle ends of the shoelace 20 are clamped by the strap clamping claw 8 from the top of the vertical seat 33, the two ends of the shoelace 20 will be pulled upward relative to the vertical seat 33 as the strap clamping claw 8 moves upward, and the self-weight wheel 34 passively moves up along the vertical long groove 332; when the self-weight wheel 34 moves up to slightly above the intermediate wheel 36, the middle part of the shoelace 20 will be separated from the intermediate wheel 36, and combined with the bottom surface of the wedge block 35 guiding the middle part of the shoelace 20 outward, the shoelace 20 can finally be smoothly separated from the loading positioning assembly 3.

[0065] It also includes a lifting auxiliary mechanism 4, such as Figure 6 As shown, the lifting auxiliary mechanism 4 includes a lifting seat 44 installed on the side of the support seat 41 and moved up and down by a lifting driving power 43 and a lifting guide rail 42.

The contour block 46 moves upward and is fitted between the pressure blocks 32 on both sides, and the pins 45 are fitted into the shoe holes of the shoe upper 10.

[0066] In this embodiment, the support base 41 is installed on the side of the turntable base 11 .

[0067] When in use, the lifting auxiliary mechanism 4 moves upward, so that the profiling block 46 moves upward and passes through the supporting part of the translation seat 23, and the upper 10 is placed on the supporting part. The middle part of the upper 10 will be supported by the profiling block 46, and the shoe holes on both sides of the upper 10 will be respectively fitted into the pins 45 on both sides of the profiling block 46 to achieve the positioning of the upper 10; then, force is applied to the quick pressing head 31, so that the pressing block 32 presses down on the upper 10 on both sides of the shoe holes, so as to achieve the fixation of the upper 10 on the translation seat 23 and complete the loading of the upper 10.

[0068] like Figure 4 As shown, the loading and positioning assembly 3 is installed on the turntable 1 via the translation mechanism 2, the turntable 1 is installed on the turntable seat 11, and the turntable 1 is driven by the rotation driving power 12 to rotate relative to the turntable seat 11 in the horizontal plane; at least a loading position and a shoelace threading position are arranged along the circumference of the turntable 1, a jacking auxiliary mechanism 4 is installed on the side of the turntable seat 11 at the loading position, and a belt connecting clamp 5 is installed on the side of the turntable seat 11 at the shoelace threading position.

[0069] In this embodiment, the turntable 1 is provided to facilitate manual loading of materials to the loading position and automatic threading of shoelaces at the shoelace threading position. The simultaneous and continuous actions at the two workstations help to improve efficiency.

[0070] In this embodiment, the setting of the translation mechanism 2 not only helps to realize and ensure the movement of the upper 10 in the Y direction when the shoelaces 20 are worn, but also can drive the loading positioning assembly 3 to move outward and closer during manual loading through the action of the translation mechanism 2 to facilitate the loading operation.

[0071] In one embodiment, two groups of loading and positioning components 3 are respectively installed on the turntable 1 via two groups of translation mechanisms 2.

The belt connecting seat 57 is slidably mounted on the belt connecting lifting seat 53 along the X direction via a belt connecting translation guide rail 56, and a belt connecting clamping claw 5 is installed on the belt connecting seat 57; the two belt connecting clamping claws 5 installed on the opposite sides of the synchronous belt 54 move toward or away from each other to form a group, which is coordinated with the threading of the shoelace 20 on the same shoe upper 10; the synchronous belt 54 is driven by a motor 542 via a driving wheel 541 for circular transmission.

[0079] This embodiment also provides a method for using the automatic shoelace tightening device, comprising the following steps:

[0080] Step 1: Load the upper 10 and the shoelace 20 respectively, and clamp and fix the upper 10 on the loading and positioning assembly 3. Specifically:

[0081] Loading of the vamp 10: the lifting auxiliary mechanism 4 works, the profiling block 46 moves upward through the supporting portion of the translation seat 23, and the vamp 10 is placed on the supporting portion. The middle part of the vamp 10 will be supported by the profiling block 46, and the shoe holes on both sides of the vamp 10 will be respectively fitted into the pins 45 on both sides of the profiling block 46 to achieve the positioning of the vamp 10; then, force is applied to the quick pressing head 31, so that the pressing block 32 presses down on the vamp 10 on both sides of the shoe hole, and the vamp 10 is fixed on the translation seat 23, and the loading of the vamp 10 is completed; the lifting auxiliary mechanism 4 moves downward and disengages.

[0082] Loading of the shoelace 20: The middle part of the shoelace 20 is hung above the middle wheel 36, and the two ends of the shoelace 20 are respectively wound downward under the self-weight wheel 34, and then the two ends of the shoelace 20 are moved up and the bundle ends are inserted into the socket 331 at the top of the vertical seat 33 to complete the loading of the shoelace 20.

[0083] The turntable 1 rotates, so that the loading and positioning assembly 3 clamped with the shoelace 20 and the upper 10 moves to the shoelace threading position, that is, rotates below the strap inserting clamping jaw 8 and above the strap connecting clamping jaw 5.

[0084] Step 2: The shoelace clamping claws 8 clamp the ends of the shoelace 20, and the two shoelace clamping claws 8 insert the ends of the shoelace 20 downward into the shoe holes of the vamp 10 from top to bottom.

[0085] After the lace insertion claws 8 clamp the two ends of the shoelace 20 on the feeding positioning assembly 3, the two ends of the shoelace 20 are inserted downward into the shoe holes of the vamp 10. At the same time, they can be hung on the shoelace 20 by the lace pulling mechanism 9, and the shoelace 20 can be slightly tightened and flattened through the upward movement of the lace pulling mechanism 9; when the lace insertion claws 8 clamp the shoelace 20 and move up to tighten the shoelace 20, the lace pulling mechanism 9 can move downward to avoid the movement of the lace insertion claws 8 and facilitate the next action of flattening the shoelace 20.

[0086] In the first insertion round of the strap clamp 8, as the strap clamp 8 moves, the two ends of the shoelace 20 will be pulled upward relative to the vertical seat 33, and the self-weight wheel 34 will passively move upward along the vertical long groove 332; when the self-weight wheel 34 moves upward to slightly above the intermediate wheel 36, the middle part of the shoelace 20 will be separated from the intermediate wheel 36, combined with the bottom surface of the wedge block 35 guiding the middle part of the shoelace 20 outward, so that the shoelace 20 can finally be smoothly separated from the loading and positioning assembly 3.

[0087] Step 3: The lace clamping claw 5 catches the two ends of the shoelace 20 from below the vamp 10, and combined with the movement of the translation mechanism 2, the lace clamping claw 5 inserts the two ends of the shoelace 20 upward into the other pair of shoe holes.

[0088] Step 4: In combination with the movement of the translation mechanism 2, the strap insertion clamp 8 and the strap connection clamp 5 cooperate to clamp the ends of the shoelace 20 from the top and bottom of the vamp 10 in turn, repeating the second and third steps to thread the shoelace 20 on the vamp 10, and the strap insertion clamp 8 releases the clamping of the ends of the shoelace 20.

[0089] Step 5: The turntable 1 rotates, and the shoe upper 10 with the shoelace 20 is rotated to the loading position, and the material is unloaded manually, and then loaded.

[0090] The present invention effectively replaces manual work, greatly improves and ensures the efficiency and effect of shoelace threading, is particularly suitable for threading flat shoelaces, and has good practicality.

[0091] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
