[0039] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0040] See also Figures 1 to 5 The figure shows a shoe production line of the present invention, which includes an outsole production line 1, a shoe body production line 2, a first oven 3, and a second oven 4, wherein the outsole production line 1 is used for processing the outsole, the shoe body production line 2 is used for processing the shoe body, the first oven 3 is used for baking the treatment agent on the outsole and the treatment agent on the shoe body, and the second oven 4 is used for baking the glue on the outsole and the glue on the shoe body.

[0041] Specifically, see Figure 1 and Figure 4 As shown, the outsole production line 1 includes: an outsole treatment agent spraying unit 11, an outsole glue spraying unit 12, and an outsole conveying line 13. The outsole treatment agent spraying unit 11 is used to spray the treatment agent on the outsole; the outsole glue spraying unit 12 is used to spray glue on the outsole; the outsole conveying line 13 is used to sequentially convey the outsole to the outsole treatment agent spraying unit 11, the first oven 3, the outsole glue spraying unit 12, and the second oven 4 to complete the processing of the outsole.

[0042] See also Figure 1 and Figure 5 As shown, the shoe production line 2 includes: a grinding unit 21, a line drawing unit 22, a roughening unit 23, a shoe treatment agent spraying unit 24, a shoe glue spraying unit 25, a shoemaking tooling conveyor line 26, a shoemaking tooling recovery line 27, and a transfer device 28. Among them, the grinding unit 21 is used to grind the bottom of the shoe body to make the sole flat; the line drawing unit 22 is used to draw lines on the shoe body; the roughening unit 23 is used to roughen the shoe body to facilitate the bonding of the shoe body; the shoe treatment agent spraying unit 24 is used to spray the treatment agent on the shoe body; the shoe glue spraying unit 25 is used to spray glue on the shoe body; the shoemaking tooling conveyor line 26 is used to sequentially convey the shoemaking tooling 20 equipped with the shoe last 10 to the grinding unit 21, the line drawing unit 22, the roughening unit 23, the shoe last 10, and the shoe last 10. The shoe body treatment agent spraying unit 24, the first oven 3, the shoe body glue spraying unit 25, and the second oven 4 realize automatic processing of the shoe body at each workstation. After the shoe body processing is completed, it is removed from the shoemaking tooling 20 together with the shoe last 10. The shoemaking tooling recovery line 27 recovers the shoemaking tooling 20 to the polishing unit, and the operator installs the shoe last 10 with the shoe body to be processed on the shoemaking tooling 20; the transfer device 28 is used to transport the shoemaking tooling 20 between the shoemaking tooling conveying line 26 and the shoemaking tooling recovery line 27.

[0043] See also Figures 1 to 3As shown, the outsole conveyor line 13, the shoemaking tool conveyor line 26, and the shoemaking tool recovery line 27 are arranged from top to bottom to save space, and the outsole production line 1 and the shoe body production line 2 can share the first oven 3 and the second oven 4, which improves the utilization rate of the ovens, reduces production costs, saves processing time, and improves processing efficiency.

[0044] See also Figure 2 and Figure 3 As shown, the shoemaking tooling conveyor line 26 and the shoemaking tooling recovery line 27 are located at corresponding ends, and a transfer device 28 is provided at each end of the shoemaking tooling conveyor line 26 in the transport direction. The transfer device 28 at least includes a transfer conveyor belt 281 that can move up and down relative to the ground. Figure 3 As shown, at the end of the shoemaking tool conveyor line 26, the shoemaking tool 20 with the shoe last 10 removed is transported to the shoemaking tool recovery line 27 via the transfer device 28, see Figure 2 As shown, the shoemaking tool 20 on the shoemaking tool recovery line 27 is transported back to the shoemaking tool conveying line 26 via the transfer device 28 for installation of a new shoe last 10 .

[0045] The outsole treatment agent spraying unit 11 corresponds to the shoe body treatment agent spraying unit 24 in upper and lower positions, and the outsole glue spraying unit 12 corresponds to the shoe body glue spraying unit 25 in upper and lower positions, so as to save space of the production line.

[0046] The line drawing unit 22 , the thickening unit 23 , the shoe body treatment agent spraying unit 24 , and the shoe body glue spraying unit 25 are all provided with a shoe making tool offline conveying device 5 for conveying the shoe making tool 20 .

[0047] See also Figures 6 to 12 As shown, the shoemaking tooling offline conveying device 5 moves the shoemaking tooling 20 from the shoemaking tooling conveying line 26 to the robot 7. The ends of the robots 7 of different processing units are installed with corresponding processing devices (such as a drawing device, a roughening device, a spraying device, etc.). When the shoe body on the shoemaking tooling 20 is processed in a certain processing unit, the shoemaking tooling offline conveying device 5 transports the shoemaking tooling 20 back to the shoemaking tooling conveying line 26.

[0048] The shoemaking tooling offline conveying device 5 comprises a frame 51, a push-pull block 52 capable of sliding horizontally relative to the frame 51, and a lifting block 53 capable of sliding up and down relative to the frame 51. Figures 7 to 9 As shown, the lifting block 53 and the shoemaking tooling conveyor line 26 are arranged on the same side of the frame 51 , and the shoemaking tooling 20 is conveyed on the shoemaking tooling conveyor line 26 .

[0049] See also Figure 8 and Fig. 9As shown, the lifting block 53 can lift the shoemaking tool 20 from the shoemaking tool conveying line 26. The shoemaking tool offline conveying device 5 also includes a connecting mechanism, which includes a protrusion 54 protruding in the vertical direction and a groove 55 for the protrusion 54 to be inserted into. One of the protrusion 54 and the groove 55 is fixedly arranged on the shoemaking tool 20, and the other is fixedly arranged on the push-pull block 52. When the shoemaking tool 20 is conveyed on the shoemaking tool conveyor line 26, the protrusion 54 and the groove 55 do not contact each other; when the shoemaking tool 20 moves along the shoemaking tool conveyor line 26 to align with the push-pull block 52, the lifting block 53 lifts the shoemaking tool 20, and the protrusion 54 is inserted into the groove 55. The push-pull block 52 can pull the shoemaking tool 20 from the shoemaking tool conveyor line 26 to the frame 51, and then process the shoe body on the shoemaking tool 20. After the processing is completed, the push-pull block 52 pushes the shoemaking tool 20 back to the lifting block 53, and the lifting block 53 then transports the shoemaking tool 20 to the shoemaking tool conveyor line 26. The conveying device has a simple structure, a small load, low cost, high reliability, and is suitable for multiple shoemaking processes. In this embodiment, see Figure 8 , Fig. 9 , Fig.13 As shown, the protrusion 54 is arranged on the upper part of the shoemaking tool 20, and two mutually parallel limiting plates 521 are arranged on the lower part of the push-pull block 52. The two limiting plates 521 and the push-pull block 52 form a groove 55. Since there are many shoemaking tools 20 on the production line, the protrusion 54 is arranged on the shoemaking tool 20 to reduce the overall production cost. In this embodiment, the extension direction of the groove 55 is perpendicular to the movement direction of the push-pull block 52.

[0050] See also Fig.11 and Fig.12 As shown, a clamping mechanism corresponding to the push-pull block 52 is provided on one end of the frame 51 away from the lifting block 53, and the clamping mechanism includes at least two clamping blocks 56 that can slide horizontally toward each other, and the clamping mechanism has a clamping state and an unlocking state. When the clamping mechanism is in the clamping state, the two clamping blocks 56 are close to each other to clamp the shoe last 10, and when the clamping mechanism is in the unlocking state, the two clamping blocks 56 are away from each other, and the shoemaking tooling 20 with the shoe last 10 installed can be pulled between the clamping blocks 56 by the push-pull block 52. The clamping device can fix the shoe last 10 to prevent the shoe last 10 from moving during processing such as grinding and marking.

[0051] See also Fig.17 and Fig.18 As shown, the shoe last 10 is provided with two clamping grooves 102 . When the clamping mechanism is in a clamping state, the ends of the clamping blocks 56 can be cooperatively inserted into the clamping grooves 102 , further preventing the shoe last 10 from moving in the vertical direction.

[0052] A dustproof plate 561 located at the same height is fixedly provided on the upper part of each clamping block 56, and two corresponding dustproof plates 561 are provided with relative clearance grooves 5611. When the clamping device is in the clamping state, the two dustproof plates 561 are connected, and the shoe last 10 is clamped between the two clearance grooves 5611. This can prevent pollutants such as particles and flying dust generated during the processing from falling onto the conveying mechanism, thereby avoiding the wear of moving parts caused by this, extending the service life of the conveying device, and keeping the conveying device clean. As a preferred embodiment, the periphery of the dustproof plate 561 is provided with a baffle plate 562 extending upward, which is used to prevent pollutants on the dustproof plate 561 from falling onto the conveying device, thereby improving the dustproof ability.

[0053] See also Figure 6 , Figure 7 , Fig.11 As shown, each push-pull block 52 is correspondingly provided with two guide plates 57, which are fixed on the frame 51 and extend in a direction parallel to the movement direction of the push-pull block 52. The two guide plates 57 and the frame 51 form a guide groove 58 for the shoemaking tool 20 to slide in cooperation. The guide groove 58 can ensure that the shoemaking tool 20 is in a relatively accurate position when it is pulled onto the frame 1, thereby ensuring the processing accuracy. The end of the guide groove 58 close to the lifting block 53 is in a trumpet shape, so that the shoemaking tool 20 can enter the guide groove 58 easily.

[0054] See also Figure 6 , Figure 7 , Fig.10 , Fig.11 As shown, as a preferred embodiment, two push-pull blocks 52 are arranged on the frame 51, and the movement directions of the two push-pull blocks 52 are parallel, and each push-pull block 52 is correspondingly provided with a clamping mechanism and a guide groove 58. When the shoemaking tool conveying mechanism of the present invention is working, one push-pull block 52 pulls the shoemaking tool 20 on the shoemaking tool conveying line 26 to the robot 7 for processing, and the other push-pull block 52 pushes the processed shoemaking tool 20 back to the shoemaking tool conveying line 26, and the two push-pull blocks 52 move alternately to improve the processing efficiency.

[0055] The grinding unit 21 comprises an automatic sole grinding device 6, see Fig.13 and Fig.14 The figure shows an automatic sole polishing device, which can be used to polish the sole arranged on the shoe last 10. Fig.17 and Fig.18As shown, the shoe material can be sleeved on the shoe last 10, and the end of the shoe last 10 away from the sole is a mounting portion 101, and the shoe last 10 is connected to the shoemaking tool 20 through the mounting portion 101. The automatic sole polishing device 6 includes a polishing machine 61 for polishing the sole, a lifting mechanism 62 for disconnecting or connecting the shoe last 10 from the shoemaking tool 20, and a polishing robot 63, and the end of the polishing robot 63 has a connection portion that can be connected to the mounting portion 101. The lifting mechanism 62 includes a base 621, and at least one clamping claw assembly 622 for grabbing the shoe last 10, and the clamping claw assembly 622 is slidably arranged on the base 621. After the clamping claw assembly 622 grasps and lifts the shoe last 10, the shoe last 10 is separated from the shoemaking tooling 20, so that the grinding robot 63 can be connected to the mounting portion 101 of the shoe last 10, and then the grinding robot 63 moves the shoe last 10 to the grinding machine and grinds the sole on the shoe last 10. After the grinding is completed, the grinding robot 63 re-places the shoe last 10 at the clamping claw assembly 622, and the clamping claw assembly 622 re-installs the shoe last 10 on the shoemaking tooling 20, and the shoe last 10 can be transported to other shoemaking stations along with the shoemaking tooling 20. Therefore, the automatic sole grinding device 6 is easy to be integrated into the automatic shoemaking production line; the mounting portion 101 of the shoe last 10 can be connected to the shoemaking tooling 20 or the grinding robot 63, and has good versatility and can reduce equipment costs.

[0056] See also Fig.16 As shown, the clamping jaw assembly 622 includes a first clamping jaw 6221, a second clamping jaw 6222, and a slider 6223 that can slide up and down relative to the base 621. The first clamping jaw 6221 and the second clamping jaw 6222 are both rotatably connected to the slider 6223. When the shoe last 10 needs to be clamped, the first clamping jaw 6221 and the second clamping jaw 6222 rotate toward each other; when the shoe last 10 needs to be released, the first clamping jaw 6221 and the second clamping jaw 622 rotate away from each other. The shoe last 10 is provided with a clamping groove 102 for the first clamping jaw 6221 and the second clamping jaw 6222 to partially fit and insert, so that the clamping jaw assembly 622 can clamp the shoe last 10 more firmly.

[0057] The first clamping jaw 6221 is rotatably connected to the slider 6223 via the first axis 623, and the second clamping jaw 6222 is rotatably connected to the slider 6223 via the second axis 624. There is a distance between the first axis 623 and the second axis 624, so that when the clamping jaw assembly 622 is disengaged from the shoe last 10, the first clamping jaw 6221 and the second clamping jaw 6222 can be opened at a smaller angle, thereby reducing the stroke of the first clamping jaw 6221 and the second clamping jaw 6222 and improving the clamping force of the clamping jaw assembly 622.

[0058] See also Figures 14 to 16As shown, the lifting mechanism 62 is provided with two clamping jaw assemblies 622, and the movement directions of the two clamping jaw assemblies 622 are parallel. One clamping jaw assembly 622 is used to remove the shoe last 10 from the shoemaking tooling 20, and the polishing robot 63 transfers the removed shoe last 10 to the other clamping jaw assembly 622, which is responsible for installing the shoe last 10 on the shoemaking tooling 20, thereby improving production efficiency.

[0059] See also Fig.13 As shown, the toe of the shoe last 10 is arranged on the shoemaking tool 10 in a direction away from the clamping jaw assembly 622 to facilitate clamping of the clamping jaw assembly 622 .

[0060] In summary, a shoemaking production line of the present invention integrates outsole processing and shoe body processing, and can realize spraying treatment agent and glue on the outsole, as well as grinding, marking, roughening, spraying treatment agent and glue on the shoe body, thereby reducing manual work as much as possible, ensuring production quality, reducing labor costs, and avoiding labor injuries to workers; at the same time, the outsole processing and shoe body processing are layered and produced synchronously, which improves production efficiency, saves production space, and can make full use of the first oven 3 and the second oven 4, improve equipment utilization rate, and reduce the cost of the production line.
