Description

Technical area

[0001] The present application relates to the field of activation and bonding technology, in particular to a self-adapting integrated precision system for activating and bonding shoe materials. State of the art

[0002] Shoes have a long history of development. The most primitive footwear, sewn from animal skins, emerged as early as the Neolithic Yangshao culture over 5,000 years ago. Shoes served as a protective tool for humans to prevent foot injuries. Originally, fur-trimmed footwear was invented to prevent foot problems or trauma under specific circumstances. The evolution of footwear led to the diversity of models and functions that is ubiquitous today.

[0003] Material activation and bonding is a key process in shoe manufacturing. Shoe components (such as the upper, midsole, and outsole) must be precisely bonded to the shoe blank fixed on the last using hot-melt adhesives or activator substances. Conventional systems have the following shortcomings: Manually measuring the material dimensions and alignment of the strips is inefficient and error-prone, leading to high scrap rates. The use of resistance heating or open convection ovens causes temperature fluctuations, leading to inconsistent material activation. Local overheating or incomplete melting impairs bond strength. Fixed stop blocks and uniform pressure parameters make it difficult to quickly change between different shoe categories (sports, leather, children's shoes) and cause high changeover costs. The decentralized control of the units (material feed, transfer, pressing) leads to asynchronous workflows. This slows down the production cycle and is incompatible with intelligent production lines. Contents of this application

[0004] On this basis, the aim of the present application is to provide a self-adapting integrated precision system that reduces manual labor and increases efficiency.

[0005] This application covers the following technical solutions.

The advantageous effects of the present application are:

[0007] In the present application, the shoe material is transported by the transfer device from the material feed device to the activation box for activation. After activation, the transfer device applies the shoe material to the shoe body to be processed on the shoe last, and the hold-down device presses the shoe material and the shoe body to be processed together, effectively combining the functions of activation and pressing in one device. The system is easy to operate, safe, and efficient. The temperature-stabilizing device heats the shoe material on the material feed device with hot air to prevent curling of the shoe material, which would impair bonding efficiency.The temperature control device is located in the activation box. It measures the temperature in the activation box via the temperature sensor and transmits the temperature signal to the temperature controller. The temperature controller controls the switching on and off of the heating plate, thereby achieving temperature control. The inspection module is used to measure the size of the shoe material and adjust the distance between the two material stop plates on the sides of the transfer device to fine-tune the placement of the shoe material. The image camera is used to check the position of the shoe last. Depending on the position of the shoe last, the angle of the shoe material is adjusted via the rotary cylinder of the transfer device so that it better fits the shoe body to be processed and processing efficiency is improved.

It is obvious that the described embodiments represent only a portion of the embodiments of the present application and do not encompass all embodiments. All other embodiments that a person skilled in the art can achieve without creative effort based on the embodiments of the present application fall within the scope of the present application.

[0009] In the description of the present application, it should be noted that the directions or positional relationships indicated by terms such as "vertical," "top," "bottom," and "horizontal" are based on the directions or positional relationships shown in the accompanying drawings and are intended only to simplify the description of the present application. They do not mean or imply that the designated devices or elements have a particular orientation or must be constructed and operated in a particular orientation. They are therefore not to be understood as limiting the present application. Furthermore, the terms "first," "second," "third," and "fourth" are for descriptive purposes only and are not to be interpreted as indicating relative importance.

[0010] In the description of the present application, it should also be noted that the terms "establish," "install," "connect," and "connect" are to be understood in their broadest sense, unless expressly stated or limited otherwise. For example, it may refer to a fixed connection, a detachable connection, or an integrated connection; a mechanical connection or an electrical connection; a direct connection or a connection via an intermediate medium; or a connection between two elements. A person skilled in the art will understand the specific meaning of the above terms in the present application based on the specific circumstances.

[0011] Fig. 1 to 7 show some embodiments of the present application relating to a self-adapting, integrated precision system for activating and bonding shoe materials, comprising a control panel 10, a frame 11, a material feed device 20, a transfer device 30, an activation box 40, a hold-down device 50, and a material intake control device 60; wherein the control panel 10 is connected to the frame 11; the frame 11 is connected to a temperature-stabilizing device 70; the material feed device 20 is arranged below the temperature-stabilizing device 70; the transfer device 30 comprises a gripping device 35, wherein the gripping device 35 is equipped with a testing module 36 for checking the dimensions of a shoe material 23, and the testing module 36 is arranged above the material feed device 20;the activation box 40 is arranged on one side of the transfer device 30, wherein the activation box 40 comprises a heating plate 41 and a temperature control device 80 connected to the heating plate 41, wherein the temperature control device 80 comprises a temperature sensor 81 and a temperature controller 82; the hold-down device 50 is arranged on one side of the activation box 40, and the hold-down device 50 comprises a plurality of image cameras 51, wherein the image cameras 51 are arranged above the material take-up control device 60; the material take-up control device 60 is arranged below the hold-down device 50, wherein the material take-up control device 60 serves to place a shoe last 61, and the image cameras 51 serve to check the position of the placed shoe last 61.

[0012] Furthermore, the inspection module 36 is integrated into the gripping device 35 to scan the contour dimensions (e.g., length, width, curvature) of the shoe material 23 above the material feed device 20 in real time. Compared to conventional manual measurement, this effectively reduces errors and provides an accurate database for subsequent activation treatment and bonding positioning, thereby avoiding bonding errors due to dimensional deviations of the shoe material 23.

[0013] Several image cameras 51 are arranged around the shoe last 61 and serve to detect the position of the shoe last 61. Using image processing techniques (e.g., edge detection, angle calculation), the inclination angles and position deviations of the shoe last 61 can be quickly detected, eliminating the inefficiency of conventional devices that rely on manual visual inspection. This is particularly suitable for the automated production of shoe lasts with complex surfaces.

[0014] As in Fig. As shown in Figure 1, the control panel 10 is connected to the material feed device 20, the transfer device 30, the heating plate 41, the hold-down device 50, and the material take-up control device 60, respectively. By controlling the material feed device 20, the transfer device 30, the heating plate 41, the hold-down device 50, and the material take-up control device 60 via the control panel 10, manual labor is effectively replaced and efficiency is increased.

[0016] Specifically, the material feeding device 20 comprises, as shown in Fig. 5, a material feed electric cylinder 21, a material feed floor plate 22, and a plurality of limit assemblies 90; the material feed electric cylinder 21 serves to raise and lower the material feed floor plate 22; the material feed floor plate 22 serves to place the shoe material 23, and the plurality of limit assemblies 90 are arranged on both sides of the material feed floor plate 22. Specifically, the material feed electric cylinder 21 drives the material feed floor plate 22 upward, thereby feeding the shoe material 23, while at the same time, according to the size of the shoe material 23, the material feed distance is adjusted by the limit assembly 90 to ensure normal feeding of the shoe material 23 and prevent falling during lifting, which would impair processing.

[0017] Specifically, as in Fig. 5, two limit assemblies 90 are arranged, each limit assembly 90 comprising a material stop plate 91, a material stop connecting plate 92, a first sliding block 93, a first sliding rail 94, a material stop bottom plate 95, a second sliding block 96, and a second sliding rail 97; wherein the material stop plate 91 is arranged on one side of the material stop connecting plate 92; the material stop connecting plate 92 is connected to the first sliding block 93; the first sliding block 93 is movably connected to the first sliding rail 94; the first sliding rail 94 is fixed above the material stop bottom plate 95; the material stop bottom plate 95 is connected above the second sliding block 96; the second sliding block 96 is movably connected to the second sliding rail 97; and the second sliding rail 97 is connected to the frame 11.The inspection module 36 and the limit assembly 90 form an intelligent control loop for "inspection, feedback, and regulation" via the operation panel 10, thereby achieving fully automatic adaptive adjustment of the positioning of the shoe material 23. Specifically, the inspection module 36 is connected to the operation panel 10 and acquires the dimensions of the shoe material 23 in real time via the inspection module 36. The operation panel 10 synchronously calculates the target distance between the two material stop plates 91 and activates a cylinder or other drive device to drive the first sliding block 93 and the second sliding block 96, which slide on the first slide rail 94 and the second slide rail 97, respectively, to adjust the distance between the two material stop plates 91, thereby effectively improving the positioning accuracy and accommodating different material sizes.In some embodiments, the control panel 10 may be an existing technology control system, such as a PLC or an ARM industrial computer.

[0018] As in Fig. 6, the transfer device 30 further comprises a first linear module 31, a second linear module 32, a transfer lifting cylinder 33, and a rotary cylinder 34; wherein the first linear module 31 is connected to the frame 11 and serves to drive the second linear module 32; the second linear module 32 is connected to the first linear module 31, and the second linear module 32 serves to drive the transfer lifting cylinder 33; the transfer lifting cylinder 33 is connected to the rotary cylinder 34; the rotary cylinder 34 is connected to the gripping device 35, which serves to grip the shoe material 23. Specifically, the transfer lifting cylinder 33 begins to lower when the material feeding device 20 feeds the shoe material 23, and the shoe material 23 is gripped via the gripping device 35. Under the drive of the second linear module 32, the transfer lifting cylinder 33 moves and transports the shoe material 23 into the activation box 40 for activation.After activation, the shoe material 23 is transported via the first linear module 31 above the material take-up control device 60. The transfer lifting cylinder 33 brings the shoe material 23 into contact with a shoe body to be processed on the shoe last 61, thereby completing the transfer. In one embodiment, the gripping device 35 can be a vacuum suction cup or another existing device with a gripping function for gripping the shoe material 23.

[0019] In particular, as in Fig. As shown in Figure 4, the temperature sensor 81 is arranged inside the activation box 40. The temperature sensor 81 is connected to the temperature controller 82, which is connected to the heating plate 41. The temperature controller 82 serves to receive signals from the temperature sensor 81 to start and stop the heating plate 41. Specifically, the temperature inside the activation box 40 is measured by the temperature sensor 81, and the temperature signal is transmitted to the temperature controller 82. The temperature controller 82 controls the starting and stopping of the heating plate 41 to achieve temperature control.

[0020] Specifically, the hold-down device 50 comprises, as shown in Fig. 2, a press-down drive module 52 and a press-down block 53 are shown; the press-down drive module 52 serves to raise and lower the press-down block 53. Specifically, the press-down drive module 52 can be an electric cylinder, a gas cylinder, or another module with a lifting and lowering function to press the press-down block 53 downward, compressing the shoe material 23 and the shoe body to be processed, which can replace manual pressing and improve efficiency.

[0021] As in Fig. As shown in Figure 7, the material take-up control device 60 includes a pressure plate 62, an adjustment bracket 63, an adjustment screw 64, a transmission rod 65, and a positioning pin 66. The pressure plate 62 is connected to the top of the adjustment bracket 63. The two ends of the adjustment screw 64 are each connected to an adjustment link block 67, to each end of which an adjustment plate 68 is hinged. One end of the adjustment plate 68 is hinged to the drive rod 65. The positioning pin 66 is connected to the top of the drive rod 65, and the positioning pin 66 serves to insert and secure the shoe last 61.When the positioning pin 66 needs to be raised, the adjusting screw 64 in the two adjusting link blocks 67 is rotated, thereby moving the adjusting link blocks 67 inward, and moving the adjusting plates 68 on both sides of the adjusting link blocks 67 to both ends, thereby raising the drive rod 65 to adjust the height of the positioning pin 66 and thus ensuring the pressing pressure between the shoe body to be machined in the shoe last 61 and the shoe material 23.

[0022] Specifically, as in Fig.1, the image camera 51 is connected to the control panel 10, and the control panel 10 is connected to the rotary cylinder 34. Specifically, the image camera 51 serves to check the applied position of the last 61, and depending on the applied position of the last 61, the control panel 10 controls the rotary cylinder 34 to adjust the angle of the shoe material 23 to better fit the shoe body to be processed, thereby improving processing efficiency.

[0023] In the present application, the shoe material 23 is transported by the transfer device 30 from the material feed device 20 to the activation box 40 for activation. After activation, the transfer device 30 applies the shoe material 23 to the shoe body to be processed on the shoe last 61, and the hold-down device 50 presses the shoe material 23 and the shoe body to be processed together, effectively combining the functions of activation and pressing in one device. The system is easy to operate, safe, and efficient. The temperature-stabilizing device 70 heats the shoe material 23 on the material feed device 20 with hot air to prevent the shoe material 23 from curling, which would impair the bonding efficiency.The temperature control device 80 is arranged in the activation box 40. It measures the temperature in the activation box 40 via the temperature sensor 81 and transmits the temperature signal to the temperature controller 82. The temperature controller 82 controls the switching on and off of the heating plate 41, thereby achieving temperature control. The inspection module 36 is used to measure the size of the shoe material 23 and to adjust the distance between the two material stop plates 91 on the sides of the transfer device 30 in order to adjust the placement of the shoe material 23. The image camera 51 is used to check the position of the shoe last 61. Depending on the position of the shoe last 61, the angle of the shoe material 23 is adjusted via the rotary cylinder 34 of the transfer device 30 so that it is better adapted to the shoe body to be processed and processing efficiency is improved.

[0024] The above description merely represents some technical solutions of the present application, which are described in a relatively concrete and detailed manner, but should not be understood as limiting the scope of the patent claims.
