Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, specifically to a system for applying adhesive to shoes. Background Technology

[0002] Adhesive bonding is a common shoe-making process that uses adhesives to bond the upper and sole together to form a shoe. Adhesives consist of solvents and resins; the solvents include some volatile components. The adhesive application process is a major contributor to organic waste gas generation in shoe manufacturing. Furthermore, because production lines cannot allow adhesives to cure naturally (requiring a long time), they need to accelerate the curing process, leading to increased concentrations of organic waste gas in the workshop. With increasingly stringent health and environmental standards in various regions, automated painting systems and waste gas collection systems are gradually being adopted. Existing automated painting systems can be equipped with multiple sensors to scan and identify the areas to be coated with adhesive, and algorithms to generate painting paths and perform the painting operation, significantly reducing the amount of manual adhesive application. However, in actual operation, although automated painting systems reduce manual labor, the amount of adhesive used is still greater than that used manually. After traditional manual application of glue and lamination of the upper and bottom, it is still necessary to clean the upper surface with a cleaning agent. There are many types of cleaning agents. Environmentally friendly ones are generally industrial ethanol, but often strong cleaning agents are needed to remove the residues adhering to the upper surface. These cleaning agents all have volatile organic components. Furthermore, with the adoption of automatic glue spraying, more glue is used in the automatic glue spraying operation, and some of the glue adheres to the upper surface as glue mist. Therefore, more cleaning is required accordingly. Utility Model Content

[0003] To address the above shortcomings, the purpose of this invention is to provide an adhesive application system that reduces the impact of adhesive mist.

[0004] Therefore, this utility model provides a system for applying adhesive to shoes, including an auxiliary device. The auxiliary device includes a housing with a cavity inside. The top surface of the housing has an opening, the shape of which matches the edge shape of the upper and last assembly structure. The upper and last assembly structure is placed upside down in the housing, and the area of ​​the upper and last assembly structure to be glued is exposed at the opening of the housing. An automatic glue spraying system sprays glue onto the exposed target area to be glued.

[0005] Furthermore, the auxiliary device is located in the automatic glue spraying process, which is equipped with a conveyor belt. The auxiliary device is located on the conveyor belt, and the automatic glue spraying system is located on one or both sides of the conveyor belt in the box.

[0006] Furthermore, the system includes a top plate extending from one end of the molding production line to the other. The molding production line includes an automatic glue spraying process. The box is fixed on the top plate, and a gas collection pipe is installed above the box for drawing gas from inside the box. Both ends of the box are set as manual operation positions.

[0007] Furthermore, a number of windows are provided on one side of the housing, and the windows correspond to the positions of the automatic glue spraying system. The windows are equipped with baffles made of transparent material, and the baffles can be opened.

[0008] Furthermore, the auxiliary device is provided with an elastic strip along the opening. When the upper and last combination structure is inserted into the opening, the elastic strip abuts against the edge of the upper and last combination structure to prevent the sprayed glue from contacting the upper.

[0009] Furthermore, the outer shell is provided with a positioning block inside, and the shoe last is provided with a positioning groove corresponding to the position of the shoe opening, so that the positioning block can be inserted into the positioning groove for cooperation.

[0010] Furthermore, the outer casing is provided with a shielding component that can cover the opening to seal the internal cavity when the auxiliary device is not filled with the upper and last assembly structure, thus preventing adhesive mist from entering the cavity from the opening.

[0011] Furthermore, the side wall of the outer casing is provided with a strip-shaped hole, one end of which is provided with a limiting groove. A pull rod is disposed in the strip-shaped hole, and a film is fixed on the pull rod. The pull rod can move into the limiting groove so that the film covers the opening.

[0012] Furthermore, a compression spring is provided between the pull rod and the side wall.

[0013] Furthermore, it also includes an automatic sealing component, which is fixed on the box below the conveyor belt. The limiting groove and the strip hole are provided with a beveled transition. The end of the pull rod is provided with a cylindrical limiting block, which cooperates with the strip hole. The automatic sealing device includes a striking rod. When the limiting block of the auxiliary device moves to contact the striking rod under the action of the conveyor belt, the striking rod pushes the pull rod to the beveled side. Under the action of the spring tension, the pull rod enters the limiting groove along the beveled side.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] This invention discloses a system for applying adhesive to shoes. The upper and last are housed within a closed shell, with the midsole and the foot area glued to the midsole exposed through an opening in the shell. The automatic adhesive spraying system does not affect the upper within the closed shell. The adhesive spraying process is enclosed in a sealed box, with a gas collection pipe at the top to create negative pressure suction within the sealed space. This solves the problem of the large amount of adhesive used by the automatic spraying system negatively impacting the environment and the upper. In a specific embodiment of this invention, considering that some auxiliary devices are idle during the production process, if the opening is open, the adhesive sprayed by the system could enter and affect subsequent use. Therefore, a shielding component is provided to prevent this. Attached Figure Description

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Reference Figures 1 to 4As shown, a system for applying adhesive to shoes according to this utility model includes an auxiliary device 5. The auxiliary device 5 includes a housing 501 with a cavity inside. An opening 502 is provided on the top surface of the housing 501. The shape of the opening 502 matches the bottom edge shape of the upper and last combination structure 6. The upper and last combination structure 6 is placed upside down in the housing 501, and the area of ​​the upper and last combination structure 6 to be glued is exposed at the opening 502 of the housing. An automatic glue spraying system sprays glue onto the exposed target area to be glued. In this embodiment, the auxiliary device 5 described above is closed on all sides except for the top opening 502. The interior of the outer shell 501 provides space for placing the upper and last assembly structure 6. A rectangular positioning groove is provided at the position corresponding to the shoe opening of the last. A positioning block 503 is provided inside the outer shell 501. The shape of the positioning block 503 matches the rectangular positioning groove. The positioning block 503 and the positioning groove can be fixed together using a strong magnet, or the cavity in the outer shell 501 can be formed to resemble the surface of the last. When the upper and last assembly structure is placed inside the outer shell 501, stable placement is achieved. (Refer to...) Figure 3 As shown, the auxiliary device 5 has an elastic strip 504 along the opening 502. When the upper and last assembly structure 6 is inserted into the opening 502, the elastic strip 504 abuts against the edge of the upper and last assembly structure 6 to prevent the sprayed glue from contacting the upper. The elastic strip 504 serves two purposes: first, to facilitate the insertion of the upper and last assembly structure into the outer casing 501; and second, to provide a seal. (Refer to...) Figure 1 As shown, the auxiliary device 5 is located in the automatic glue spraying process 1, which is part of the molding production line. The top plate 3 extends from one end of the molding production line to the other. The automatic glue spraying process 1 is equipped with a sealed box 2, which is fixed to the top plate 3. A gas collection pipe 7 is installed above the box 2 to draw gas from inside the box 2. The conveyor belt 4 enters from one end of the box 2 and exits from the other end. Curtains are installed at the inlet and outlet of the conveyor belt to reduce the leakage of organic gas. The auxiliary device 5 is fixed to the conveyor belt 4, which can be a chain. The automatic glue spraying system is located on one or both sides of the conveyor belt 4 in the box 2. The two ends of the box 2 are set as manual operation stations, which are used to manually or otherwise insert the upper and last combination structure 6 into the auxiliary device 5, or to separate the upper and last combination structure 6 from the auxiliary device 5, to replenish glue in areas where glue spraying is incomplete, and to clean dirty areas.

[0024] In the above embodiments, reference is made to Figure 1 As shown, several windows are provided on one side of the housing 2, corresponding to the positions of the automatic glue spraying system. Each window has a transparent baffle 8 that can be opened. The baffle 8 allows observation of the automatic glue spraying system's operation; any abnormalities or malfunctions can be addressed by opening the baffle 8.

[0025] In the above embodiments, reference is made to Figure 4As shown, the outer casing 501 of the auxiliary device 5 is equipped with a shielding component, which can cover the opening 502 to seal the internal cavity when the upper and last assembly structure 6 is not placed inside the auxiliary device 5, preventing glue mist from entering the cavity from the opening 502. Specifically, the side wall of the outer casing 501 is provided with a strip-shaped hole, one end of which is provided with a limiting groove 506. A pull rod is set in the strip-shaped hole, and a film is fixed on the pull rod. The pull rod can move into the limiting groove 506 so that the film covers the opening 502. A compression spring is provided between the pull rod and the side wall. It also includes an automatic closing component, which is fixed on the box 2 below the conveyor belt 4. A bevel 505 is provided between the limiting groove 506 and the strip-shaped hole for transition. The end of the pull rod is provided with a cylindrical limiting block 9, which cooperates with the strip-shaped hole. The automatic sealing device includes a bumper 10, which can be U-shaped. When the limiting block 9 of the auxiliary device 5 moves to contact the bumper 10 under the action of the conveyor belt 4, the U-shaped bumper engages with the limiting blocks 9 on both sides of the auxiliary device 5. The bumper pushes the pull rod to the inclined side 505, and the pull rod enters the limiting groove 506 along the inclined side 505 under the action of the spring tension. In this embodiment, the pull rod is manually reset at the manual operation station, and the opening 502 is opened to insert the upper and last combination structure 6. The auxiliary device enters the box 2 under the action of the conveyor belt 4 for automatic glue spraying. After glue spraying, the glued upper and last combination structure is taken out at another manual operation station. It should be noted that, in order to facilitate the removal of the combination structure, the outer shell 501 can be designed as a top and bottom flip-top structure. After the upper and last combination structure 6 is taken out, the conveyor belt 4 and the auxiliary device 5 enter the box 2 for automatic glue spraying. Figure 5 The lower stroke, as shown, contacts the impact rod 10. Under the action of the impact rod 10, the limiting block and pull rod are pushed to the vicinity of the limiting groove 506, and under the action of the inclined plane and spring force, they enter the limiting groove 506, achieving automatic closure. When the auxiliary device reaches the manual operation position at the entrance, the operator resets and places the side panel and last assembly structure 6. This automatic closure structure ensures that, under non-full-load operation, some idle auxiliary devices will not enter the glue, thus avoiding affecting subsequent use.
