Description

Technical Field

[0001] This invention relates to the field of footwear manufacturing, and more particularly to a multi-axis intelligent adhesive spraying system for mixed-thread production of shoe soles. Background Technology

[0002] In the footwear manufacturing industry, the bonding of the sole and upper is a crucial process, and adhesive spraying, as a key step before bonding, directly impacts the quality and efficiency of the final product. With the continuous development of the footwear market, consumers' demands for footwear styles and sizes are becoming increasingly diverse, requiring footwear manufacturers to efficiently and accurately produce various sizes of footwear.

[0003] Traditional methods of applying adhesive to shoe soles have many drawbacks. Firstly, some companies use manual adhesive application, which is not only labor-intensive but also prone to problems such as glue leakage and over-application, leading to unstable product quality and a high defect rate. Secondly, manual adhesive application is inefficient and cannot meet the demands of large-scale production, limiting the company's production capacity and market competitiveness.

[0004] On the other hand, although some companies have introduced automated glue spraying equipment, these devices are often single-function and can usually only perform glue spraying operations on specific models of shoe soles. When faced with mixed production lines of different shoe sole models, traditional automated glue spraying equipment cannot flexibly adjust the glue spraying parameters and the position and angle of the glue spraying components, making it difficult to meet diverse production needs. This results in companies needing to equip themselves with multiple glue spraying machines of different models, increasing equipment procurement costs, space occupation, and equipment maintenance complexity.

[0005] In addition, some existing automated glue spraying equipment cannot make real-time adjustments based on the precise position and angle of the sole on the conveying device during the glue spraying process. The positioning between the glue spraying component and the sole is not precise enough, which can easily cause glue spraying position deviation, affecting the adhesion between the sole and the upper, and thus affecting the overall quality of the shoe.

[0006] Therefore, developing an intelligent glue spraying system that can efficiently and accurately spray glue continuously onto different types of shoe soles and automatically adjust the glue spraying components according to the position and angle of the shoe sole has become a technical problem that the footwear manufacturing industry urgently needs to solve. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-axis intelligent glue spraying system for shoe sole mixing production, which can efficiently and accurately spray glue continuously onto different models of shoe soles.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a multi-axis intelligent glue spraying system for shoe sole mixing production, the multi-axis intelligent glue spraying system for shoe sole mixing production comprising: An electric three-axis displacement platform, wherein the electric three-axis displacement platform is mounted on a frame; The selection unit includes a selection motor mounted on the electric three-axis displacement platform and a selection platform fixed on the rotating shaft of the selection motor; Several angle-adjusting motors are arranged around the selection platform along the rotation shaft of the selection motor; Several glue spraying sections are provided, each corresponding to a shaft of the angle adjustment motor. Each glue spraying section is connected to a glue supply system via a flexible pipe. A solenoid valve is provided at the connection point between the flexible pipe and the glue spraying section. Each glue spraying section has a glue spraying groove on its spraying surface. The glue spraying groove on each glue spraying section is used to spray glue onto different models of shoe soles. The shape of the glue spraying groove is consistent with the shape of the bonding area between the shoe sole and the shoe upper. A conveying device is disposed below the glue spraying section, and shoe soles to be glued are conveyed on the conveying device; An intelligent control unit is installed on the conveying device. The intelligent control unit is electrically connected to the electric three-axis displacement platform, the selection motor, the angle adjustment motor, the solenoid valve, and the conveying device. The intelligent control unit controls the electric three-axis displacement platform, the selection motor, the angle adjustment motor, the solenoid valve, and the conveying device according to the model, position, and angle of the shoe sole.

[0009] In one embodiment, the electric three-axis displacement platform includes an X-axis lead screw and slider mechanism, a Y-axis lead screw and slider mechanism, and a Z-axis lead screw and slider mechanism. The Y-axis lead screw and slider mechanism is mounted on the frame, the Z-axis lead screw and slider mechanism is mounted on the slider of the Y-axis lead screw and slider mechanism, the X-axis lead screw and slider mechanism is mounted on the slider of the Z-axis lead screw and slider mechanism, and the selection motor is mounted on the slider of the X-axis lead screw and slider mechanism.

[0010] In one embodiment, the adhesive spraying unit includes: The main body has the solenoid valve mounted on it. The main body has a glue-containing cavity inside it. One end of the glue-containing cavity is connected to the solenoid valve, and the other end of the glue-containing cavity is connected to the glue-spraying groove. A sliding groove is provided in the middle of the glue-spraying surface of the main body. A clamping block, which is slidably fitted onto the slide groove; An elastic element is disposed within the slide groove, one end of which is connected to the main body and the other end of which is connected to the clamping block.

[0011] In one embodiment, the distance between the edge of the clamping block and the adhesive spray groove is 0.5~1cm.

[0012] In one embodiment, the conveying device includes: support; The active roller and the driven roller are rotatably mounted on the support. A conveyor belt, which is mounted on the driving roller and the driven roller; A conveyor motor is fixed on the bracket, and the shaft of the conveyor motor is connected to the drive roller.

[0013] In one embodiment, a support portion is further included, the support portion being disposed on the conveying device, the support portion comprising: A base plate, which is fixed to the bracket; An electric telescopic rod is fixed to the base plate and is electrically connected to the intelligent control unit. A support platform is fixed to the telescopic end of the electric telescopic rod. The support platform is located below the glue spraying section. When the intelligent control unit controls the conveyor motor to stop running, the intelligent control unit controls the electric telescopic rod to extend so that the top surface of the support platform is in close contact with the bottom surface of the upper conveyor belt.

[0014] In one embodiment, the intelligent control unit includes: A high-precision camera is mounted on the bracket and is used to monitor the model, position, and angle of the shoe sole entering the adhesive spraying area. The processor is electrically connected to the high-precision camera, the electric three-axis displacement platform, the selection motor, the angle adjustment motor, the solenoid valve, and the conveyor motor.

[0015] In one embodiment, a T-shaped identification mark is also included, which is attached to a specific position on the upper surface of the sole, and the T-shaped identification mark has a different color on different models of soles, and the high-precision camera identifies the T-shaped identification mark.

[0016] The above-described technical solutions in the embodiments of the present invention have at least the following technical effects or advantages: The multi-axis intelligent glue spraying system for mixed-line production of shoe soles provided in this invention utilizes a conveying device to continuously transport shoe soles to be sprayed with glue. When the shoe sole moves to the area below the glue spraying section, the system can automatically complete a series of glue spraying operations, including shoe sole positioning, glue spraying section selection, position and angle adjustment, and glue spraying. Then, it continues to transport the next shoe sole for glue spraying, realizing continuous operation of shoe sole glue spraying, greatly improving production efficiency, and effectively meeting the needs of large-scale production.

[0017] Furthermore, the system incorporates a selection unit where a selection motor drives a selection platform to rotate, aligning the glue spraying units corresponding to different sole models with the appropriate spraying position. The intelligent control unit precisely controls the selection motor's rotation angle based on the sole model, selecting the appropriate spraying unit for the current sole type. This design allows the system to flexibly handle the glue spraying needs of different sole models on a single production line, eliminating the need for separate spraying equipment for each model. This reduces equipment procurement costs and space requirements, while enhancing equipment versatility and production flexibility for businesses.

[0018] Furthermore, the intelligent control unit accurately identifies the type, position, and angle of the sole after it moves to below the adhesive spraying section. Based on the precise position of the sole, it controls the electric three-axis displacement platform to adjust horizontally, ensuring the selected adhesive spraying section is directly above the sole. Based on the angle of the sole, it controls the angle adjustment motor to rotate, aligning the adhesive spraying section with the horizontal angle of the sole, ensuring the adhesive spraying channel precisely aligns with the area on the sole that will bond to the upper. This automatic adjustment mechanism based on the actual condition of the sole greatly improves the accuracy of adhesive spraying, avoids problems such as glue leakage and excess glue, guarantees the quality of the bonding between the sole and the upper, and thus improves the overall quality of the shoe.

[0019] The entire glue spraying process is automatically controlled by the intelligent control unit, which coordinates the operation of components such as the electric three-axis displacement platform, selection motor, angle adjustment motor, solenoid valve, and conveying device, eliminating the need for manual intervention. This not only reduces errors caused by manual operation and improves production efficiency and product quality stability, but also reduces reliance on manual labor, lowers labor costs, and avoids potential safety hazards associated with manual operation, thereby enhancing the safety and reliability of the production process.

[0020] Finally, by setting a spray groove on the spraying surface of the spraying unit that matches the shape of the bonding area between the sole and the upper, during the spraying process, the glue is sprayed out from the spray groove, quickly and evenly covering the ring-shaped area on the sole and upper to be bonded with glue in one go. Compared to the traditional method of using a glue gun to spray glue along this ring-shaped area, there is no need for the glue gun to move repeatedly on the sole surface, which greatly shortens the spraying time, significantly improves the spraying efficiency, and further enhances the overall production speed.

[0021] In summary, the multi-axis intelligent glue spraying system for shoe sole mixing production of the present invention has significant effects in improving production efficiency, enhancing equipment applicability, ensuring glue spraying accuracy, improving glue spraying efficiency, and realizing automated production.

[0029] Please see Figures 1 to 3This application provides a multi-axis intelligent glue spraying system for shoe sole mixing production, including an electric three-axis displacement platform 1, a selection unit 2, several angle adjustment motors 3, several glue spraying units 4, a conveying device 5, and an intelligent control unit. The electric three-axis displacement platform 1 is mounted on a frame. The selection unit 2 includes a selection motor 21 mounted on the electric three-axis displacement platform 1 and a selection platform 22 fixed to the rotating shaft of the selection motor 21. The angle adjustment motors 3 are arranged around the rotating shaft of the selection motor 21 on the selection platform 22. The glue spraying units 4 are correspondingly mounted on the rotating shafts of the angle adjustment motors 3. The glue spraying units 4 are connected to the glue supply system through flexible pipes 46. Solenoid valves 45 are provided at the connection positions between the flexible pipes 46 and the glue spraying units 4. Each glue spraying unit 4 has a glue spraying groove 41 on its spraying surface, and the glue spraying groove 41 on each glue spraying unit 4 is used to spray glue onto different models of shoe soles 9. The shape of the glue spraying groove 41 is consistent with the shape of the adhesive area between the shoe sole 9 and the upper. The conveying device 5 is located below the glue spraying section 4, and conveys the shoe soles 9 to be glued. The intelligent control unit is located on the conveying device 5 and is electrically connected to the electric three-axis displacement platform 1, the selection motor 21, the angle adjustment motor 3, the solenoid valve 45, and the conveying device 5. The intelligent control unit controls the electric three-axis displacement platform 1, the selection motor 21, the angle adjustment motor 3, the solenoid valve 45, and the conveying device 5 according to the model, position, and angle of the shoe sole 9.

[0030] The multi-axis intelligent glue spraying system for mixed-line production of shoe soles 9 provided by this invention utilizes a conveying device 5 to transport the shoe soles 9 to be glued. When the shoe soles 9 move with the conveying device 5 to below the glue spraying section 4 (e.g. Figure 1 As shown), at this time, the intelligent control unit recognizes the sole 9 and controls the conveying device 5 to stop operating, so that the sole 9 stops below the glue spraying section 4. Then, the intelligent control unit recognizes the type of sole 9 and its precise position and angle. Furthermore, the intelligent control unit controls the selection motor 21 to rotate a specific angle according to the type of sole 9, so that the glue spraying section 4 matching the type of sole 9 rotates to the lowest position (glue surface horizontally downwards), completing the selection of the glue spraying section 4. Simultaneously, the intelligent control unit controls the electric three-axis displacement platform 1 to adjust horizontally according to the precise position of the sole 9, so that the selected glue spraying section 4 is directly above the sole 9. At the same time, the intelligent control unit controls the angle adjustment motor 3 to rotate according to the angle of the sole 9, so that the glue spraying section 4 rotates to the same horizontal angle as the sole 9, so that the glue spraying groove 41 of the glue spraying section 4 aligns with the area on the sole 9 that is to be bonded to the upper (e.g., ...). Figure 2 (As shown). Then, the intelligent control unit controls the electric three-axis displacement platform 1 to descend until the adhesive spraying surface of the adhesive spraying unit 4 is in close contact with the sole 9. After that, the intelligent control unit opens the solenoid valve 45 on the adhesive spraying unit 4, so that the adhesive is accurately and quickly sprayed onto the area on the sole 9 that is to be bonded to the upper (as shown). Figure 3(As shown). After the glue spraying is completed, the intelligent control unit controls the solenoid valve 45 to close and controls the electric three-axis displacement platform 1 to rise so that the glue spraying part 4 is detached from the sole 9. Then, the control unit controls the conveying device 5 to continue operating until the next sole 9 moves under the glue spraying part 4. The above steps are repeated to continuously spray glue onto the sole 9.

[0031] The multi-axis intelligent glue spraying system for mixed-line production of shoe soles 9 provided by this invention can continuously spray glue onto shoe soles 9 with high efficiency, and can spray glue onto different models of shoe soles 9 on a single glue spraying line, making it highly adaptable. Furthermore, the glue spraying unit 4 can automatically adjust according to the specific position and angle of the shoe sole 9 in the glue spraying area, ensuring accuracy. The entire glue spraying process is fully automatic, requiring no manual intervention. Moreover, by setting a glue spraying groove 41 on the glue spraying surface of the glue spraying unit 4, which matches the shape of the bonding area between the shoe sole 9 and the upper, the glue can be quickly sprayed from the glue spraying groove 41 to fully cover the annular area where the shoe sole 9 and the upper are bonded, resulting in higher efficiency compared to the traditional method of using a glue gun to spray glue along this annular area. Finally, because this system is equipped with an electric three-axis displacement platform 1 and an angle adjustment motor 3, the position and angle of the shoe sole 9 can be changed at will when it is placed on the conveyor device 5. There is no need to restrict the specific placement position and angle. Compared with traditional glue spraying equipment that requires the shoe sole 9 to be placed in a specific position (such as the center of the conveyor device 5) and at a specific angle (such as the length of the shoe needing to be perpendicular to the running direction of the conveyor belt 52), the process of placing the shoe sole 9 to be glued onto the conveyor belt 52 is easy and convenient.

[0032] In one embodiment, the electric three-axis displacement platform 1 includes an X-axis lead screw and slider mechanism 11, a Y-axis lead screw and slider mechanism 12, and a Z-axis lead screw and slider mechanism 13. The Y-axis lead screw and slider mechanism 12 is mounted on the frame, the Z-axis lead screw and slider mechanism 13 is mounted on the slider of the Y-axis lead screw and slider mechanism 12, and the X-axis lead screw and slider mechanism 11 is mounted on the slider of the Z-axis lead screw and slider mechanism 13. A selector motor 21 is mounted on the slider of the X-axis lead screw and slider mechanism 11. The X-axis lead screw and slider mechanism 11, the Y-axis lead screw and slider mechanism 12, and the Z-axis lead screw and slider mechanism 13 are all adjusted by rotating the lead screw driven by a motor. The lead screw and slider mechanism has high adjustment accuracy, enabling the glue spraying part 4 to be accurately adjusted to be directly above the sole 9 and accurately lowered during glue spraying to ensure that the glue spraying part 4 is tightly attached to the sole 9.

[0033] like Figure 6-7As shown, in one embodiment, the adhesive spraying unit 4 includes a main body 42, a clamping block 43, and an elastic element 44. A solenoid valve 45 is disposed on the main body 42, and an adhesive receiving cavity 421 is provided within the main body 42. One end of the adhesive receiving cavity 421 is connected to the solenoid valve 45, and the other end of the adhesive receiving cavity 421 is connected to the adhesive spraying groove 41. A sliding groove is provided in the middle of the adhesive spraying surface of the main body 42. The clamping block 43 is slidably fitted onto the sliding groove. The elastic element 44 is disposed within the sliding groove, with one end connected to the main body 42 and the other end connected to the clamping block 43.

[0034] During the glue spraying process, the intelligent control unit controls the Z-axis lead screw slider mechanism 13 to move downward, causing the glue spraying part 4 to descend until the pressing block 43 is pressed against the sole 9. As the glue spraying part 4 continues to descend, the force between the pressing block 43 and the sole 9 causes the pressing block 43 to overcome the elastic force of the elastic element 44 (which may be a spring, sheet, or other structure) and slide towards the inside of the main body 42. The elastic force of the elastic element 44 is then applied to the sole 9 through the pressing block 43, thereby pressing and fixing the sole 9 onto the conveying device 5, preventing the sole 9 from moving during the glue spraying process and causing deviation in the glue spraying position. After the adhesive-sprayed surface of the main body 42 comes close to the sole 9, the intelligent control unit controls the Z-axis lead screw slider mechanism 13 to stop moving and controls the solenoid valve 45 to open, so that the adhesive in the flexible pipe 46 (specifically, a bent corrugated pipe) is input into the adhesive cavity 421, thereby squeezing out the original adhesive in the adhesive cavity 421 from the lower adhesive spraying groove 41. After being squeezed out of the adhesive spraying groove 41, the adhesive adheres to the lower sole 9, thus completing the adhesive spraying process of the sole 9. Then, the intelligent control unit controls the Z-axis lead screw slider mechanism 13 to move upward, while simultaneously controlling the solenoid valve 45 to close, so that the adhesive stops being output from the adhesive spraying groove 41. The upward movement of the Z-axis lead screw slider mechanism 13 causes the clamping block 43 to release the sole 9, so that the adhesive-sprayed sole 9 can continue to move forward under the conveying of the conveying device 5.

[0035] Specifically, regarding the descent distance of the Z-axis lead screw slider mechanism 13 during glue spraying, since the thickness of different models of shoe soles 9 varies, the intelligent control unit, after identifying the model of the shoe sole 9, will set the descent distance of the Z-axis lead screw slider mechanism 13 according to the pre-input thickness corresponding to the shoe sole 9 model, so as to ensure that during glue spraying, the Z-axis lead screw slider mechanism 13 can accurately lower the glue spraying part 4 to a position close to the shoe sole 9.

[0036] like Figure 7As shown, in one embodiment, the distance between the edge of the clamping block 43 and the glue spraying groove 41 is 0.5~1cm. By leaving a distance of 0.5~1cm between the edge of the clamping block 43 and the glue spraying groove 41, the clamping block 43 is prevented from obstructing the glue spraying of the glue spraying groove 41, and the clamping action of the clamping block 43 can cover most of the area of ​​the sole 9 to the maximum extent, thereby improving the fixing effect of the sole 9. At the same time, when spraying glue on some thinner soles 9, the clamping block 43 with its edge close to the glue spraying groove 41 can also prevent the edge of the sole 9 from lifting, thereby improving the quality of glue spraying.

[0037] In one embodiment, the conveying device 5 includes a support 51, a drive roller, a driven roller, a conveyor belt 52, and a conveyor motor 53. The driven roller is rotatably mounted on the support 51. The conveyor belt 52 is mounted on the drive roller and the driven roller. The conveyor motor 53 is fixed to the support 51, and its shaft is connected to the drive roller. The conveyor motor 53 drives the drive roller to rotate, thereby driving the conveyor belt 52 and the driven roller to rotate, thus transporting the shoe sole 9 on the conveyor belt 52.

[0038] In one embodiment, a support portion 7 is further included, which is disposed on the conveying device 5. The support portion 7 includes a base plate 71, an electric telescopic rod 72, and a support platform 73. The base plate 71 is fixed to the bracket 51. The electric telescopic rod 72 is fixed to the base plate 71 and is electrically connected to the intelligent control unit. The support platform 73 is fixed to the telescopic end of the electric telescopic rod 72 and is located below the glue spraying section 4. When the intelligent control unit controls the conveyor motor 53 to stop operating, the intelligent control unit controls the electric telescopic rod 72 to extend, so that the top surface of the support platform 73 is in close contact with the bottom surface of the upper conveyor belt 52.

[0039] like Figure 4 As shown, a support unit 7 is provided to prevent the sole 9 from moving downwards during the glue spraying process due to the elastic deformation of the conveyor belt 52. When the intelligent control unit stops the conveyor motor 53, it controls the electric telescopic rod 72 to extend, so that the top surface of the support platform 73 is in close contact with the bottom surface of the upper conveyor belt 52. The support platform 73 provides support force and supports the conveyor belt 52. This prevents the conveyor belt 52 from deforming and bending downwards when subjected to pressure from the clamping block 43 in the glue spraying section 4, which would reduce the horizontal height of the sole 9 and affect the glue spraying process.

[0040] Furthermore, after the adhesive is applied, before the intelligent control unit controls the conveyor device 5 to continue operating, the intelligent control unit controls the electric telescopic rod 72 to retract, causing the support platform 73 to descend and detach from the conveyor belt 52, thus preventing friction between the conveyor belt 52 and the support platform 73 during operation and protecting the conveyor belt 52.

[0041] In one embodiment, the intelligent control unit includes a high-precision camera 61 and a processor 62. The high-precision camera 61 is mounted on a bracket 51 and is used to monitor the model, position, and angle of the shoe sole 9 entering the adhesive spraying area. The processor 62 is electrically connected to the high-precision camera 61, the electric three-axis displacement platform 1, the selection motor 21, the angle adjustment motor 3, the solenoid valve 45, and the conveying motor 53.

[0042] In one embodiment, a T-shaped identification mark 8 is also included. The identification mark is affixed to a specific position on the upper surface of the sole 9, and the color of the T-shaped identification mark 8 is different on different models of soles 9. The high-precision camera 61 identifies the T-shaped identification mark 8. The high-precision camera 61 accurately determines the specific model of the sole 9 based on the color of the T-shaped identification mark 8, determines the position of the sole 9 based on the position of the T-shaped identification mark 8, and determines the angle of the sole 9 based on the angle of the T-shaped identification mark 8. Thus, the high-precision camera 61 can accurately and quickly obtain the model, position, and angle information of the sole 9.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
