Description

Technical Field

[0001] This invention relates to the field of slipper manufacturing technology, and in particular to a slipper production line and manufacturing method. Background Technology

[0002] Slippers typically lack a back section and are made by piecing together the upper and sole.

[0003] Currently, the edging and sewing of disposable slippers in hotels are all done by hand, which is labor-intensive and demanding. Furthermore, the quality of the slippers requires a high level of skill from the workers, resulting in inconsistent production quality.

[0004] Therefore, there is an urgent need for a slipper production line and production method, as well as solutions to the aforementioned problems. Summary of the Invention

[0005] One objective of this invention is to provide a slipper production line that enables automated slipper production, reduces labor intensity, and improves stability.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The slipper production line includes:

[0008] The shoe upper folding unit includes a shoe upper feeding assembly and a shoe upper folding assembly, wherein the shoe upper feeding assembly is used to feed the shoe upper to the shoe upper folding assembly, and the shoe upper folding assembly is used to fold the shoe upper;

[0009] The upper-sole composite unit includes a sole feeding assembly, an upper-sole composite assembly, an upper-sole composite holding assembly, an upper-sole dragging and holding mechanism, and an upper-sole sewing mechanism. The sole feeding assembly is used to feed the sole to the upper-sole composite holding assembly. The upper-sole composite assembly is used to combine the folded upper onto the sole. The upper-sole composite holding assembly is used to hold the sole and the folded upper into a shoe body to be sewn. The upper-sole dragging and holding mechanism is used to hold and drag the shoe body to be sewn. The upper-sole sewing mechanism is used to sew the shoe body to be sewn that is dragged by the upper-sole dragging and holding mechanism.

[0010] As an optional embodiment of the slipper production line, the upper-sole composite assembly includes a transfer mechanism and a gripper mechanism. The gripper mechanism includes a gripper seat, a first gripper plate, a second gripper plate, and a gripping drive. The first gripper plate is disposed on the gripper seat, and the second gripper plate is movably disposed on the gripper seat and opposite to the first gripper plate. The gripping drive is throttlely connected to the second gripper plate and is used to drive the second gripper plate closer to or further away from the first gripper plate to grip or release the folded upper. The gripper seat is disposed on the transfer mechanism, and the transfer mechanism is used to cyclically move the gripper mechanism between the upper folding assembly and the upper-sole composite retaining assembly.

[0011] As an optional embodiment of the slipper production line, the transfer mechanism includes a support frame, a rotating frame, a rotating drive component, a transfer application traverse mechanism, and a transfer application lifting mechanism. The rotating frame is rotatably mounted on the support frame. The rotating drive component is connected to the rotating frame and is used to drive the rotating frame to rotate. The transfer application traverse mechanism is mounted on the rotating frame. The transfer application lifting mechanism is mounted on the transfer application traverse mechanism. The gripper seat is mounted on the transfer application lifting mechanism.

[0012] As an optional embodiment of the slipper production line, the upper folding unit further includes an upper folding table, and the upper feeding component and the upper folding component are each corresponding to the upper folding table and are disposed on the corresponding upper folding table. There are two upper folding units.

[0013] The upper and sole composite unit includes an upper and sole composite frame. The sole feeding component, the upper and sole composite holding component, the upper and sole dragging and holding mechanism and the upper and sole sewing mechanism are all corresponding to the upper and sole composite frame and are set on the corresponding upper and sole composite frame. There are two upper and sole composite units.

[0014] Two of the aforementioned composite upper and two of the aforementioned folding upper are arranged circumferentially around the support frame. The rotating frame includes four horizontal bars that radiate outward from the center. The rotating transverse movement mechanism, the rotating lifting mechanism, and the gripper mechanism are all corresponding to the horizontal bars. The rotating transverse movement mechanism is slidably mounted on the corresponding horizontal bar.

[0015] As an optional embodiment of the slipper production line, it further includes an upper material bin and a sole material bin. Two upper folding frames are distributed adjacently in the circumferential direction on the outer periphery of the support frame. The upper material bin is located between two adjacent upper folding frames in the circumferential direction. Two upper-sole composite frames are distributed adjacently in the circumferential direction on the outer periphery of the support frame. The sole material bin is located between two upper-sole composite frames in the circumferential direction. The upper feeding assembly is used to take material from the upper material bin, and the sole feeding assembly is used to take material from the sole material bin.

[0016] As an optional embodiment of the slipper production line, the upper-sole composite retaining assembly includes a support platform and an upper-sole temporary pressing assembly. The support platform has a feeding station, and the sole feeding assembly is used to feed the sole to the feeding station. The upper-sole temporary pressing assembly includes an auxiliary frame, a translation component, a translation drive component, a vertical guide component, a temporary holding component, and a downward pressing drive component. The auxiliary frame is disposed on the support platform. The translation component is slidably disposed on the auxiliary frame in the horizontal direction. The vertical guide component is disposed on the translation component. The temporary holding component is slidably disposed on the vertical guide component. The translation drive component is used to drive the translation component to slide so that the temporary holding component is close to or away from the top of the feeding station. The downward pressing drive component is used to drive the temporary holding component to slide up and down so as to press and hold the sole and the folded upper on the support platform to form the shoe body to be sewn, or to release the shoe body to be sewn.

[0017] As an optional embodiment of the slipper production line, the upper and sole dragging and holding mechanism includes a mobile robot and a dragging and holding member. The dragging and holding member is disposed on the mobile robot. The mobile robot can adjust the height of the dragging and holding member so that the dragging and holding member presses against the shoe body to be sewn. The mobile robot can also translate the dragging and holding member so that the dragging and holding member drives the shoe body to be sewn to slide on the support platform.

[0018] As an optional embodiment of the slipper production line, the upper and sole composite retaining assembly further includes a sole positioning mechanism. The sole positioning mechanism includes a first conformal positioning member, a second conformal positioning member, and a positioning drive member. The first conformal positioning member and the second conformal positioning member are arranged opposite to each other on both sides of the loading station. The positioning drive member is used to drive the first conformal positioning member to move closer to or away from the second conformal positioning member.

[0019] Another objective of this invention is to provide a slipper manufacturing method that maintains the shape of the upper and the shoe body to be sewn during the automated slipper production process until the finished slippers are produced.

[0020] To achieve this objective, the present invention adopts the following technical solution:

[0021] A slipper manufacturing method, implemented based on any of the slipper production lines described above, includes the following steps:

[0022] S1. When the upper folding assembly folds and maintains the shape of the upper, the upper-sole composite assembly holds the upper.

[0023] S2. The shoe upper folding assembly releases the folded shoe upper, and the upper-sole composite assembly moves the shoe upper onto the sole.

[0024] S3. While the upper and sole composite component continuously holds the upper, the upper and sole composite retaining component presses the upper against the sole, so that the upper and the shoe body remain as a shoe body to be sewn together.

[0025] S4. The upper and sole composite assembly loosens the shoe upper.

[0026] S5. The surface-to-bottom dragging and holding mechanism presses against and holds the shoe body to be sewn;

[0027] S6. The upper and lower composite retaining component loosens the shoe body to be stitched;

[0028] S7. The upper and lower dragging and holding mechanism drags and holds the shoe body to be sewn, and works with the upper and lower sewing mechanism to complete the sewing of the shoe body to be sewn.

[0029] Another object of the present invention is to provide a slipper production method that maintains the shape of the upper and the shoe body to be sewn during the automated production process of slippers until the finished slippers are produced.

[0030] To achieve this objective, the present invention adopts the following technical solution:

[0031] A slipper production method, implemented based on an optional embodiment of the slipper production line described above, includes the following steps:

[0032] S1. When the shoe upper folding assembly folds the shoe upper, the rotating lifting mechanism raises and lowers the shoe upper so that the gripper mechanism is vertically equal to the shoe upper and the gripper mechanism opens.

[0033] S2. When the shoe upper folding assembly maintains the shape of the shoe upper, the lateral shifting mechanism laterally shifts the gripper mechanism, causing the gripper mechanism to move to both sides of the shoe upper, and the gripper mechanism closes to grasp the shoe upper;

[0034] S3. The shoe upper folding assembly is released and reset;

[0035] S4. The lifting mechanism and the transverse movement mechanism together drive the gripper mechanism to move to the installation position;

[0036] S5. The rotary drive component drives the rotary frame to rotate;

[0037] S6. The rotating lifting mechanism and the rotating lateral movement mechanism together drive the gripper mechanism to move, so that the shoe upper is assembled on the shoe sole;

[0038] S7. While the gripper mechanism continuously holds the upper, the upper-to-sole composite retaining component presses the upper against the sole, keeping the upper and the shoe body as a shoe body to be sewn together.

[0039] S8. The gripper mechanism opens, releasing the shoe upper, and the transfer mechanism resets.

[0040] S9. The surface-to-bottom dragging and holding mechanism presses against and holds the shoe body to be sewn;

[0041] S10, The upper and lower composite retaining assembly loosens the shoe body to be stitched;

[0042] S11. The upper and lower dragging and holding mechanism drags and holds the shoe body to be sewn, and works with the upper and lower sewing mechanism to complete the sewing of the shoe body to be sewn.

[0043] Beneficial effects:

[0044] The slipper production line provided by this invention includes a sole feeding component that feeds the sole to an upper-sole composite holding component, an upper feeding component that feeds the upper to an upper folding component, an upper folding component that folds the upper, and an upper-sole composite component that assembles the folded upper onto the sole. The upper-sole composite holding component holds the sole and the folded upper together to form the shoe body to be sewn, ensuring that the sole and upper are relatively fixed and have a certain degree of compactness, facilitating direct sewing of the shoe body by the upper-sole sewing mechanism. An upper-sole dragging holding mechanism replaces the upper-sole composite holding component in holding the shoe body to be sewn and drags it, working in conjunction with the upper-sole sewing mechanism to complete the sewing of the shoe body, producing a finished slipper. This slipper production line achieves automated slipper production, reduces labor intensity, and improves the stability of the production process and product quality.

[0045] The slipper production method provided by this invention enables the upper and the shoe body to be sewn to be transferred hand-by-hand between different processes, so that the upper and the shoe body to be sewn are always kept under pressure during production flow, and finished slippers are obtained.

[0063] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0064] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0065] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0066] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0067] like Figure 1 As shown, this embodiment provides a slipper production line, specifically including an upper folding unit 1 and an upper-sole composite unit. In this embodiment, both the upper and sole used to manufacture the slippers have a certain amount of elastic deformation.

[0068] like Figure 1 As shown, the upper folding unit 1 includes an upper feeding assembly 10 and an upper folding assembly 12. The upper feeding assembly 10 is used to feed the upper to the upper folding assembly 12, and the upper folding assembly 12 is used to fold the upper. The upper-sole composite unit includes a sole feeding assembly 2, an upper-sole composite assembly 3, an upper-sole composite holding assembly 4, an upper-sole dragging and holding mechanism 5, and an upper-sole sewing mechanism 6. The sole feeding assembly 2 is used to feed the sole to the upper-sole composite holding assembly 4. The upper-sole composite assembly 3 is used to combine the folded upper onto the sole. The upper-sole composite holding assembly 4 is used to hold the sole and the folded upper into a shoe body to be sewn. The upper-sole dragging and holding mechanism 5 is used to hold and drag the shoe body to be sewn. The upper-sole sewing mechanism 6 is used to sew the shoe body to be sewn dragged by the upper-sole dragging and holding mechanism 5.

[0069] The slipper production line provided in this embodiment supplies the sole to the upper-sole composite retaining assembly 4 via the sole feeding component 2, and the upper feeding component 10 to the upper folding assembly 12. The upper folding assembly 12 folds the upper. After the upper is folded, the upper-sole composite assembly 3 combines the folded upper onto the sole. The upper-sole composite retaining assembly 4 holds the sole and the folded upper together as the shoe body to be sewn, keeping the sole and upper relatively fixed and compact to facilitate the upper-sole sewing mechanism 6 in directly sewing the shoe body. The upper-sole dragging retaining mechanism 5 replaces the upper-sole composite retaining assembly 4 in holding the shoe body to be sewn and drags it, working in conjunction with the upper-sole sewing mechanism 6 to complete the sewing of the shoe body, producing finished slippers. The slipper production line provided in this embodiment achieves automated slipper production, reduces labor intensity, and improves the stability of production processes and product quality.

[0070] like Figures 1-5 As shown, optionally, the upper-sole composite assembly 3 includes a transfer mechanism 31 and a gripper mechanism 32. The gripper mechanism 32 includes a gripper seat 321, a first gripper plate 322, a second gripper plate 323, and a gripping drive member 324. The first gripper plate 322 is disposed on the gripper seat 321, and the second gripper plate 323 is movably disposed on the gripper seat 321 and opposite to the first gripper plate 322. The gripping drive member 324 is convexly connected to the second gripper plate 323 and is used to drive the second gripper plate 323 closer to or further away from the first gripper plate 322 to grip or release the folded upper. The gripper seat 321 is disposed on the transfer mechanism 31, which is used to cyclically move the gripper mechanism 32 between the upper folding assembly 12 and the upper-sole composite holding assembly 4. The gripper mechanism 32 is used to grip the folded upper and apply a certain clamping force to maintain the shape of the folded upper and prevent the upper from deforming back to its original shape, thus affecting the production process.

[0071] like Figures 1-5As shown, optionally, the transfer mechanism 31 includes a support frame 311, a rotating frame 312, a rotating drive member 313, a lateral transfer mechanism 314, and a lifting mechanism 315. The rotating frame 312 is rotatably mounted on the support frame 311. The rotating drive member 313 is connected to the rotating frame 312 and is used to drive the rotating frame 312 to rotate. The lateral transfer mechanism 314 is mounted on the rotating frame 312. The lifting mechanism 315 is mounted on the lateral transfer mechanism 314. The gripper seat 321 is mounted on the lifting mechanism 315. The lateral movement mechanism 314 can drive the gripper mechanism 32 on the lateral lifting mechanism 315 to move in a straight line and adjust the position of the gripper mechanism 32 in the horizontal direction. The rotating frame 312 can also adjust the position of the gripper mechanism 32 in the horizontal direction. The lateral lifting mechanism 315 can drive the gripper mechanism 32 on it to rise and fall and adjust the position of the gripper mechanism 32 in the vertical direction, so as to facilitate the alignment of the gripper mechanism 32 with the folded shoe upper, or to allow the gripper mechanism 32 to move the folded shoe upper to the sole. The transfer mechanism 31 can drive the gripper mechanism 32 to rotate, move laterally and rise and fall, and also helps to avoid interference between the gripper mechanism 32 and the transfer mechanism 31 and other structures during the transfer process.

[0072] like Figure 1 As shown, optionally, the upper folding unit 1 further includes an upper folding table 11, with the upper feeding assembly 10 and the upper folding assembly 12 each corresponding to the upper folding table 11 and disposed on the corresponding upper folding table 11. There are two upper folding units 1. The upper and sole composite unit includes an upper and sole composite table 7, with the sole feeding assembly 2, the upper and sole composite holding assembly 4, the upper and sole dragging holding mechanism 5, and the upper and sole sewing mechanism 6 each corresponding to the upper and sole composite table 7 and disposed on the corresponding upper and sole composite table 7. There are two upper and sole composite units. The two upper and sole composite tables 7 and the two upper folding tables 11 are arranged circumferentially around the support frame 311. The rotating frame 312 includes four horizontal bars that radiate from the center outwards in a transverse direction. The rotating transverse shifting mechanism 314, the rotating lifting mechanism 315, and the gripper mechanism 32 each correspond to one of the horizontal bars. The rotating transverse shifting mechanism 314 is slidably disposed on the corresponding horizontal bar.

[0073] In other words, the two sole supply components 2 supply two soles to the corresponding two upper-sole composite retaining components 4. The two upper folding components 12 can fold two uppers simultaneously. Two of the four gripper mechanisms 32 corresponding to the crossbars can simultaneously grip the two folded uppers at the two upper folding components 12, while the other two gripper mechanisms 32 can combine the gripped uppers onto the two soles, forming two shoe bodies to be sewn together, thus producing a pair of slippers simultaneously. In this embodiment, when the two crossbars are operating at the two upper folding components 12, the other two crossbars are operating at the two upper-sole composite retaining components 4. Optionally, the included angle between the four crossbars is 90°.

[0074] like Figure 1 As shown, optionally, the slipper production line also includes an upper material bin 8 and a sole material bin 9. Two upper folding tables 11 are circumferentially adjacent to each other on the outer periphery of the support frame 311. The upper material bin 8 is circumferentially located between the two adjacent upper folding tables 11. Two upper-sole composite tables 7 are circumferentially adjacent to each other on the outer periphery of the support frame 311. The sole material bin 9 is circumferentially located between the two upper-sole composite tables 7. The upper feeding component 10 is used to take material from the upper material bin 8, and the sole feeding component 2 is used to take material from the sole material bin 9. The upper material bin 8 can conveniently supply uppers to the two upper folding units 1, and the sole material bin 9 can conveniently supply soles to the upper-sole composite retaining components 4 on the two upper-sole composite units, thereby achieving high efficiency and automation of the slipper production line and reducing labor intensity and labor costs.

[0075] like Figure 6 As shown, optionally, the upper and sole composite holding assembly 4 includes a support platform 41 and an upper and sole temporary pressing assembly 42. The support platform 41 has a feeding station, and the sole feeding assembly 2 is used to feed the sole to the feeding station. The upper and sole temporary pressing assembly 42 includes an auxiliary frame 421, a translation component 422, a translation drive component 423, a vertical guide component 424, a temporary holding component 425, and a downward pressing drive component 426. An auxiliary frame 421 is mounted on a support platform 41. A translation component 422 is slidably mounted on the auxiliary frame 421 in a horizontal direction. A vertical guide component 424 is mounted on the translation component 422. A temporary holding component 425 is slidably mounted on the vertical guide component 424. A translation drive component 423 drives the translation component 422 to slide, so that the temporary holding component 425 is close to or away from the top of the loading station. A downward drive component 426 drives the temporary holding component 425 to slide up and down, so as to press and hold the sole and the folded upper on the support platform 41 to form the shoe body to be sewn, or to release the shoe body to be sewn. After the clamping mechanism of the upper and sole composite assembly 3 places the folded upper on the support platform 41, the upper and sole composite holding assembly 4 presses and holds the upper and sole together, so that both maintain a preset pressure shape.

[0076] Preferably, there are two temporary pressing components 42 for the upper and lower surfaces, which are arranged opposite each other on the left and right sides of the feeding station, so that the shape of the shoe body to be sewn can be more accurately maintained.

[0077] like Figure 7 As shown, optionally, the upper and lower sole dragging and holding mechanism 5 includes a mobile robot 51 and a dragging and holding member 52. The dragging and holding member 52 is mounted on the mobile robot 51. The mobile robot 51 can adjust the height of the dragging and holding member 52 so that the dragging and holding member 52 presses against the shoe body to be sewn. The mobile robot 51 can also translate the dragging and holding member 52 so that the dragging and holding member 52 drives the shoe body to be sewn to slide on the support platform 41. The mobile robot 51 presses the dragging and holding member 52 against the shoe body to be sewn, maintaining the compressed shape of the shoe body. The mobile robot 51 drives the dragging and holding member 52 to translate and drive the shoe body to be sewn to slide on the support platform 41, thereby cooperating with the upper and lower sole sewing mechanism 6 to complete the sewing of the shoe body to be sewn, producing a finished slipper.

[0078] like Figure 6 As shown, optionally, the upper-sole composite retaining assembly 4 further includes a sole positioning mechanism 43. The sole positioning mechanism 43 includes a first conformal positioning member 431, a second conformal positioning member 432, and a positioning drive member 433. The first conformal positioning member 431 and the second conformal positioning member 432 are arranged opposite to each other on both sides of the loading station. The positioning drive member 433 is used to drive the first conformal positioning member 431 to move closer to or away from the second conformal positioning member 432. The first conformal positioning member 431 and the second conformal positioning member 432 adjust the position of the sole by conforming to the shape of the sole surface, thereby facilitating the gripper mechanism 32 to place the folded upper onto the sole according to a preset trajectory.

[0079] The following is a further description of the working process of the slipper production line:

[0080] like Figure 2 and Figure 3 As shown, the upper feeding assembly 10 includes an upper gripping mechanism 101 and a rodless cylinder 102 for upper gripping. The rodless cylinder 102 is fixedly connected to the upper folding platform 11 by screws, and the upper gripping mechanism 101 is fixedly connected to the rodless cylinder 102 by screws. After the upper gripping mechanism 101 grips the upper from the upper storage compartment 8, it moves the gripped upper laterally to above the upper folding assembly 12 via the rodless cylinder 102. Then, the upper gripping mechanism 101 places the upper on it into the upper folding assembly 12, and then the upper feeding assembly 10 returns to its initial state. The structural design of the upper gripping mechanism 101 can be referenced from the gripper mechanism 32, and will not be described in detail here.

[0081] like Figure 3As shown, the upper folding assembly 12 includes an upper positioning mechanism 121 and an upper folding mechanism 122. The upper positioning mechanism 121 positions the upper based on the shape of its outer contour. The upper folding mechanism 122 folds the upper by pressing it down and then moving it along the contour. After the upper is placed in the upper folding mechanism 122 by the upper gripping mechanism 101, the upper positioning mechanism 121 first positions the upper, and then the upper folding mechanism 122 completes the folding. Further details on the working principle and structure of the upper folding assembly 12 can be found in existing technology and will not be elaborated here.

[0082] like Figures 2-5 As shown, the lateral movement mechanism 314 includes a lateral guide rail 3141, a lateral drive member 3142, and a lateral moving member 3143. The lateral guide rail 3141 and the lateral drive member 3142 are fixed on corresponding horizontal bars. The lateral moving member 3143 is slidably disposed on the lateral guide rail 3141. The lateral drive member 3142 is connected to the lateral moving member 3143, and the lateral drive member 3142 can drive the lateral moving member 3143 to move horizontally. The lifting mechanism 315 includes a vertical guide rail 3151, a vertical drive member 3152, and a vertical moving member 3153. The vertical guide rail 3151 and the vertical drive member 3152 are fixed on corresponding lateral moving members 3143. The vertical moving member 3153 is slidably disposed on the vertical guide rail 3151. The vertical drive member 3152 is connected to the vertical moving member 3153, and the vertical drive member 3152 can drive the vertical moving member 3153 to move vertically.

[0083] like Figure 4 and Figure 5 As shown, the gripper seat 321 includes two opposing bearing seats, which are fixedly connected to the vertical moving member 3153 by screws. One end of the second gripper plate 323 is provided with a gear shaft 326, which is rotatably mounted on the two bearing seats. The first gripper plate 322 is fixedly connected to the bearing seat or the vertical moving member 3153 by screws. The gripping drive member 324 is connected to the vertical moving member 3153 by screws. The gripping drive member 324 is a cylinder, and a rack 325 is threadedly connected to its piston shaft. The rack 325 meshes with the gear shaft 326, so that the gripping drive member 324 can drive the second gripper plate 323 to open and close relative to the first gripper plate 322, thereby realizing the gripping action of the shoe upper.

[0084] like Figure 4 and Figure 5As shown, the rotary drive component 313 includes a servo motor 3131 and a reducer 3132. The servo motor 3131 and the reducer 3132 are fixedly connected together by screws. Both are located below the support frame 311. The reducer 3132 is fixedly connected to the support frame 311 by screws. The support frame 311 is provided with a bearing seat. The rotating shaft 3133 is rotatably mounted on the bearing seat. The rotating shaft 3133 passes through the bearing seat from top to bottom, and its lower end is connected to the reducer 3132 by a coupling. Four crossbars are fixedly connected to the upper end of the rotating shaft 3133 by screws. Under the transmission action of the reducer 3132, coupling, and rotating shaft 3133, the servo motor 3131 drives the four crossbars to rotate at a certain angle according to the program setting. Combined with the gripping of the shoe upper by each gripper mechanism 32, the transfer of pairs of shoe uppers between the two shoe upper folding units 1 and the two upper-sole composite units is completed.

[0085] After the two shoe upper folding mechanisms 122 complete the folding of the two shoe uppers, the rotating frame 312 rotates, and the two transfer mechanisms 31 drive the gripper mechanism 32 to move laterally and move up and down. The two gripper mechanisms 32 grasp the two folded shoe uppers. The structure of the sole feeding assembly 2 is the same as that of the shoe upper feeding assembly 10, and will not be described again here. After the two sole feeding assemblies 2 place the soles from the sole material bin 9 onto the loading station of the two support platforms 41, they automatically reset. The rotating frame 312, transfer mechanism 31, and gripper mechanism 32 transfer the two grasped shoe uppers to the two soles respectively.

[0086] As shown in Figure 6, both the first conformal positioning component 431 and the second conformal positioning component 432 are shoe sole positioning blocks. The positioning drive component 433 consists of two shoe sole positioning cylinders, which are fixed at intervals on the upper support platform 41. The two shoe sole positioning blocks correspond one-to-one with the two shoe sole positioning cylinders and are positioned on the corresponding shoe sole positioning cylinders. After the shoe sole is placed on the support platform 41, the first conformal positioning component 431 and the second conformal positioning component 432 position it and maintain its position.

[0087] like Figure 6 As shown, the auxiliary frame 421 is fixedly connected to the support platform 41 by screws. A horizontal linear guide rail is fixed on the auxiliary frame 421. The translation component 422 is a horizontal moving plate, which is slidably set on the horizontal linear guide rail. The translation drive component 423 is fixedly connected to the auxiliary frame 421 by screws. The drive end of the translation drive component 423 is fixedly connected to the horizontal moving plate. The translation drive component 423 can drive the horizontal moving plate to make horizontal movements.

[0088] like Figure 6As shown, the vertical guide member 424 includes a vertical guide bearing and a vertical guide shaft. The vertical guide bearing is mounted on the horizontal moving plate, and the vertical guide shaft slides through the vertical guide bearing. The temporary pressing member 425 is a shoe upper pressing block, which is fixedly connected to the vertical guide shaft by screws. The downward pressing drive member 426 is fixedly connected to the horizontal moving plate by screws and is also fixedly connected to the shoe upper pressing block. The downward pressing drive member 426 can drive the shoe upper pressing block to make vertical movements, thereby realizing the pressing work of the shoe upper and the sole. In this embodiment, both the translation drive member 423 and the downward pressing drive member 426 are three-axis cylinders.

[0089] After the upper is placed on the sole, the horizontal moving plate moves horizontally and the upper pressing block moves vertically, thereby pressing down the sewing edges of the upper and sole, keeping the upper and sole as the shoe body to be sewn. Then, the first conformal positioning member 431 and the second conformal positioning member 432 are reset to release the shoe body to be sewn.

[0090] like Figure 7 As shown, the base of the mobile robot 51 is fixed to the support platform 41 with screws. The drag-holding member 52 is fixedly connected to the movable end of the mobile robot 51 with screws. The drag-holding member 52 is provided with a pressure block, which can press into the shoe body to be sewn, so as to drag the shoe body to be sewn to slide on the support platform 41. The upper and lower sewing mechanism 6 is a sewing machine with an edge-binding pull tube, which is set on the support platform 41.

[0091] After the upper and sole composite component 3 is reset, the mobile robot 51 moves the dragging and holding component 52 to press down the assembled sole and upper (i.e. the shoe body to be sewn). Then the upper and sole composite holding component 4 is reset, leaving the necessary space for the mobile robot 51 to drag the shoe body to be sewn.

[0092] After the sewing is completed, the finished slippers are taken out of the production line by the mobile robot 51 to complete the unloading of the finished slippers. Then the mobile robot 51 is reset to wait for the next batch of slippers.

[0093] This embodiment also provides a slipper production method, which is implemented based on the above-mentioned slipper production line, combined with... Figures 1-7 As shown, it includes the following steps:

[0094] S1. When the upper folding component 12 is folded and maintains the shape of the upper, the upper-sole composite component 3 grips the upper.

[0095] S2, the upper folding component 12 releases the folded upper, and the upper-to-sole composite component 3 moves the upper onto the sole;

[0096] S3. While the upper and sole composite component 3 is continuously holding the upper, the upper and sole composite retaining component 4 presses the upper against the sole, keeping the upper and the shoe body as a shoe body to be sewn together.

[0097] S4, Loosen the upper and sole composite components 3.

[0098] S5, the upper and lower dragging and holding mechanism 5 presses and holds the shoe body to be sewn;

[0099] S6. Loosen the shoe body to be stitched, as part of the upper and sole composite retaining component 4.

[0100] S7. The upper and lower dragging and holding mechanism 5 drags and holds the shoe body to be sewn, and works with the upper and lower sewing mechanism 6 to complete the sewing of the shoe body to be sewn.

[0101] This embodiment enables the shoe upper and the shoe body to be sewn to be transferred hand-by-hand between different processes, so that the shoe upper and the shoe body to be sewn are always kept under pressure during production flow, and finished slippers are obtained.

[0102] Optionally, the slipper manufacturing method includes the following steps:

[0103] S1. When the shoe upper folding assembly 12 folds the shoe upper, it uses the lifting mechanism 315 to lift and lower, so that the gripper mechanism 32 is vertically equal to the shoe upper, and the gripper mechanism 32 opens.

[0104] S2. When the shoe upper folding assembly 12 maintains the shape of the shoe upper, the transverse shifting mechanism 314 is used to transverse the gripper mechanism 32, so that the gripper mechanism 32 is moved to both sides of the shoe upper and the gripper mechanism 32 closes to grasp the shoe upper.

[0105] S3. The shoe upper folding assembly 12 is released and reset;

[0106] S4. The lifting mechanism 315 and the transverse moving mechanism 314 together drive the gripper mechanism 32 to move to the installation position.

[0107] S5, Rotary drive component 313 drives the rotating frame 312 to rotate;

[0108] S6. The rotating lifting mechanism 315 and the rotating transverse movement mechanism 314 jointly drive the gripper mechanism 32 to move, so that the upper is assembled on the sole.

[0109] S7. While the gripper mechanism 32 is continuously gripping the upper, the upper and sole composite retaining component 4 presses the upper against the sole, keeping the upper and the shoe body as a shoe body to be sewn together.

[0110] S8. The gripper mechanism 32 opens, releasing the shoe upper, and the transfer mechanism 31 resets.

[0111] S9. The upper and lower dragging and holding mechanism 5 presses and holds the shoe body to be sewn;

[0112] S10, the upper and lower composite retaining component 4 is loosened to be stitched;

[0113] S11. The upper and lower dragging and holding mechanism 5 drags and holds the shoe body to be sewn, and works with the upper and lower sewing mechanism 6 to complete the sewing of the shoe body to be sewn.

[0114] The specific operation steps for surface-bottom composite component 3 are as follows:

[0115] As the shoe upper folds, the vertical moving member 3153, under the action of the vertical driving member 3152, lowers the gripper mechanism 32 to a low position. Then, the clamping driving member 324 opens the gripper mechanism 32. After the shoe upper is folded, the horizontal moving member 3143, under the action of the horizontal driving member 3142, moves the gripper mechanism 32 laterally, causing it to scoop into the folded shoe upper. Then, the clamping driving member 324 closes the gripper mechanism 32, securing the shoe upper. The corresponding shoe upper folding mechanism 122 then resets. After resetting, the transfer mechanism 31 moves the gripper mechanism 32 and the shoe upper on it to a safe position. The gripping of the folded shoe upper is thus completed.

[0116] After both shoe uppers are gripped, the rotating frame 312 rotates, causing the four gripping mechanisms to rotate at a certain angle. After the upper and sole composite unit completes the feeding of the two soles, the upper and sole composite component 3 will perform the combination of the shoe upper and sole.

[0117] The horizontal movement mechanism 314 drives the gripper mechanism 32 and the upper on it to move horizontally, so that the upper moves to the top of the sole at the loading station. Then, the lifting mechanism 315 drives the gripper and the upper on it to a lower position, so that the upper and the sole are combined. Then, the upper and sole composite holding component 4 presses down the sewn edge of the upper, that is, presses the upper and the sole together, realizing and holding the upper and sole of the slipper to form a composite. Then, the gripper mechanism 32 opens, and the sole positioning mechanism 43 resets, leaving the necessary space for the resetting of the transfer mechanism 31. Then, the horizontal movement mechanism 314 drives the opened gripper mechanism 32 to move, so that it resets horizontally. At this time, the gripper mechanism 32 has disengaged from the upper and sole composite holding component 4. Then, the lifting mechanism 315 resets, and the upper and sole composite is completed.
