Abstract
Description
Technical Field
[0001] This utility model relates to shoe processing equipment, specifically a shoe upper gluing device. Background Technology
[0002] In footwear manufacturing, the bonding of the upper to the outsole is a crucial step that directly affects the quality and durability of the finished shoe. To ensure a good bond, pre-bonding treatment of the upper is essential, especially the area where the upper contacts the outsole (i.e., the area to be processed on the upper). This area requires meticulous sanding and gluing before bonding.
[0003] In existing automated equipment, when applying glue, the robotic arm and other equipment are usually placed in a protective box. This makes it easier for the robotic arm to move the shoe last with the shoe upper attached, and also makes it easier for the robotic arm to move the glue spray nozzle around the shoe upper processing area. However, this method has the following problems.
[0004] When applying adhesive or treatment agent, the mist-like adhesive or treatment agent can easily adhere to the outer wall of the robot arm or robot arm hose, causing corrosion to the equipment components. Utility Model Content
[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a shoe upper gluing device, which achieves gluing or application of the gluing agent by contacting the shoe upper processing area with a glue-soaked layer containing glue or treatment agent. The glue-soaked layer is formed of a soft porous material with restorative deformation (such as a sponge). By restoring deformation, the glue or treatment agent can be better bonded to the shoe upper processing area.
[0006] Specifically, a shoe upper gluing device includes a box with an upper opening. An impregnation layer soaked with a chemical agent is provided on the inner bottom of the box. The chemical agent is glue or a treatment agent. The shoe upper processing area is the area where the shoe upper contacts or separates from the impregnation layer by moving the shoe last in and out of the box. The shoe upper processing area is the area where the shoe upper contacts the outsole.
[0007] Optionally, the impregnation layer is formed of a soft, porous material with recoverable deformation.
[0008] Optionally, the impregnation layer has an arc-shaped groove adapted to the shoe upper processing area.
[0009] Optionally, the box body is provided with a drug addition tube that contacts the impregnation layer.
[0010] Optionally, the housing is provided with several agent addition tubes arranged around the impregnation layer.
[0011] Optionally, the reagent addition tube is connected to a glue storage chamber via a pipe, and the pipe is equipped with a valve.
[0012] Optionally, a lid is provided at the opening end of the box body. Optionally, the lid is two cover plates, and the inner edges of the two cover plates have a fitting arc surface that can fit with the shoe upper attached to the shoe last.
[0013] This utility model has the following advantages:
[0014] This invention relates to a shoe upper gluing device. It achieves gluing or application of a coating layer, which is impregnated with adhesive or a treatment agent, by contacting the shoe upper processing area. The adhesive layer is formed of a soft, porous material with resilience (such as a sponge). Due to its resilience, especially during compression, the area of the shoe upper processing area in contact with the adhesive layer is depressed, while the uncompressed area remains depressed and may even tend to converge towards the processing area. This results in better bonding between the adhesive or treatment agent and the processing area. This invention avoids the environmental or equipment impact caused by sprayed adhesive or treatment agent during traditional spraying methods.
[0015] When a soft, porous material (such as a sponge) forms a dipped layer that comes into contact with the shoe upper processing area, the agent (glue or treatment agent) in the dipped layer is applied to the processing area through extrusion. As the processing area separates from the dipped layer, the dipped layer recovers its shape, absorbing excess agent from the processing area and preventing it from becoming overloaded. The agent can be replenished through an agent addition tube and a glue reservoir, ensuring the dipped layer has sufficient agent. Attached Figure Description

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0026] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
[0027] As described in the background section, in existing automated equipment, when applying glue, the robotic arm and other equipment are usually placed in a protective box. This is beneficial for the robotic arm to move the shoe last with the shoe upper attached, and also makes it convenient for the robotic arm to move the glue spray nozzle around the shoe upper processing area. However, this method has the following problems.
[0028] When applying adhesive or treatment agent, the mist-like adhesive or treatment agent can easily adhere to the outer wall of the robot arm or robot arm hose, causing corrosion to the equipment components.
[0029] To overcome the above problems, such as Figures 1-8 As shown, this embodiment provides a shoe upper gluing device, including a box 100 with an upper opening. An impregnation layer 500, which is soaked in a chemical agent, is provided on the inner bottom of the box. The chemical agent is glue or a treatment agent. The shoe upper processing area 401 of the shoe upper 400 enters and exits the box through a moving shoe last 300 to contact or separate from the impregnation layer. The shoe upper processing area is the area where the shoe upper contacts the outsole. The impregnation layer 500 is formed of a soft, porous material with recovery deformation (such as sponge).
[0030] The aforementioned technical features enable the application of adhesives or treatment agents to the shoe upper processing area. This is achieved by bringing a layer soaked in adhesive or treatment agent into contact with the processing area, thus completing the application. This avoids the environmental or equipment impact caused by spraying adhesives or treatment agents during traditional spraying methods. Furthermore, the adhesive layer formed from a soft, porous material (such as a sponge) applies the agent (adhesive or treatment agent) to the processing area through compression when in contact with it. As the processing area separates from the adhesive layer, the layer recovers its shape, absorbing excess agent from the processing area and preventing excessive agent buildup.
[0031] In use, the shoe upper is moved into the box through the shoe last 300 via the lateral moving mechanism 301 (such as a cylinder) and the longitudinal moving mechanism 302 (such as a cylinder). The shoe upper is pressed down to a certain depth and held for a certain period of time. Then, the shoe upper is slowly lifted by the shoe last. After the shoe upper is separated from the glued layer, it is held for a certain period of time before being moved apart to facilitate the application of glue or treatment agent to the next shoe upper.
[0032] To improve the contact effect between the shoe upper processing area and the dipped layer, or to enhance the wrapping effect of the dipped layer on the contact area after contact, in one embodiment, the dipped layer has an arc-shaped groove 501 adapted to the shoe upper processing area. This arc-shaped groove allows the dipped layer to make more precise contact with the shoe upper processing area, preventing excessive coverage of the contact area of the dipped layer on the shoe upper during pressing (because excessive coverage can cause the glue or treatment agent to exceed the shoe upper processing area).
[0033] To ensure sufficient agent (adhesive or treatment agent) in the impregnation layer, in one embodiment, the housing is provided with agent addition pipes 600 that contact the impregnation layer. Preferably, the housing is provided with several agent addition pipes 600 arranged around the impregnation layer. The agent addition pipes are connected to a storage chamber 700 via a conduit 800, which is equipped with a valve 801. The agent is stored in the storage chamber, the flow of the agent is controlled by the valve, and the agent can be guided to the impregnation layer from multiple directions via the agent addition pipes, ensuring that the impregnation layer is sufficiently and uniformly impregnated with agent. When adding agent, the valve is opened, and the agent is delivered to the impregnation layer by squeezing or other power (such as a pump).
[0034] To reduce the risk of foreign objects entering the box, in one embodiment, a lid 200 is provided at the opening end of the box. Optionally, the lid consists of two cover plates 201, the inner edges of which have a fitting arc surface 2011 that can fit against the shoe upper attached to the shoe last. The lid reduces the risk of foreign objects entering the box and affecting the gluing or finishing process.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
