Description

Technical Field

[0001] The invention relates to the field of shoe processing, in particular to a shoe upper processing method. Background Art

[0002] In the process of shoe manufacturing, the bonding of the upper and the outsole is a crucial process, which is directly related to the quality and durability of the finished shoe. To ensure the bonding effect, the upper treatment before bonding is indispensable, especially the area where the upper and the outsole contact (i.e. the area to be processed), which needs to be carefully polished and glued before bonding.

[0003] The current automated upper processing equipment used in the market usually combines the upper with the last, and then uses a precise robot to move the last and the upper as a whole to the designated polishing area. After polishing, the robot moves the last and the upper to the glue spraying area for gluing. This process seems efficient, but it faces many challenges in actual operation.

[0004] During the grinding process, the upper material will produce a lot of powdery debris. These powders not only pollute the working environment, but also easily penetrate into the transmission mechanism of the robot and the gaps of the driving components, resulting in transmission obstruction, equipment performance degradation, and even malfunction. Although the entire equipment can be covered by a box, the robot and other equipment are all located in the box.

[0005] In the glue spraying process, the glue (or treatment agent) is transported to the nozzle of the robot through a flexible hose (the reason for using a hose is that the robot needs to move and flip during spraying, so an organic polymer hose is used to avoid affecting the movement of the robot) and sprayed out in a mist form to cover the area to be processed on the upper. However, the mist glue (or treatment agent) is highly corrosive. Once it adheres to the gap between the hose or the driving parts of the robot, it will cause corrosion damage to these parts, seriously affecting the service life of the equipment. At the same time, because the glue (or treatment agent) is corrosive to the pipeline (because the glue and treatment agent contain polymer materials, and the hose is also formed of polymer materials, the glue or treatment agent will corrode the pipeline), it is also very easy to cause blockage at the nozzle, seriously affecting the production efficiency of the equipment.

[0006] In order to deal with the negative impact of powder, glue or treatment agent on the equipment, operators have to perform tedious cleaning work regularly. This not only increases the labor intensity of operators, but also needs to be done when the equipment is stopped, which seriously affects the continuity and efficiency of the production line. Therefore, how to effectively solve the problem of equipment contamination caused by powder, glue or treatment agent during the upper treatment process has become a technical problem that needs to be solved urgently in the current footwear manufacturing field. Summary of the invention

[0007] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a shoe upper processing method, which can concentrate the grinding or glue brushing or treatment agent brushing processes of the shoe upper to be processed area in a closed box, effectively avoiding the influence of powder generated during grinding on other equipment (such as manipulators, drive motors, etc.), and also preventing the corrosion of glue or treatment agents to other equipment, thereby improving the cleanliness of the production environment and the service life of the equipment.

[0008] Specifically, a method for processing a shoe upper includes the following steps: Combine the upper with the last; The to-be-processed area of ​​the upper is sent into a processing box through a shoe last, and then the processing box is sealed, wherein the to-be-processed area is the area where the upper contacts the outsole; The workpiece located in the box cover is rotated to process the area to be processed. The workpiece is a grinding wheel or a glue brush surrounding and contacting the area to be processed. When the workpiece is a grinding wheel, the processing is grinding the area to be processed. When the workpiece is a glue brush, the processing is brushing glue on the area to be processed.

[0009] Optionally, a driving member of the working member is located outside the processing box.

[0010] Optionally, the processing box has an opening for facilitating the entry and exit of the shoe last, and a box cover is installed at the opening to achieve airtightness of the processing box.

[0011] Optionally, the box cover is two cover plates, and the two cover plates can be opened by opening horizontally, rotating, or opening opposite to each other; the inner edges of the two cover plates have a fitting arc surface, and the fitting arc surface can fit with the upper combined with the shoe last.

[0012] Optionally, when the processing is to apply glue or a treatment agent to the upper processing area, the glue brush is soaked with glue or a treatment agent, or the processing box contains glue or a treatment agent that contacts the glue brush.

[0013] Optionally, the grinding wheel is composed of multiple unit grinding wheels; the rubber brush is composed of multiple unit brushes.

[0014] Optionally, the rubber brush is composed of multiple unit brushes.

[0015] Optionally, the unit brush includes a power shaft drivingly connected to the driving member, and a plurality of long bristles are arranged on the power shaft.

[0016] The present invention has the following advantages: The present invention is a processing method for the upper processing area (the area where the upper contacts the outsole), which can concentrate the grinding or brushing of the upper processing area or brushing of the treatment agent in a closed box, effectively avoiding the influence of the powder generated during grinding on other equipment (such as manipulators, drive motors, etc.), and also preventing the corrosion of other equipment by glue, thereby improving the cleanliness of the production environment and the service life of the equipment. Compared with the traditional glue spraying, the glue brushing method has a better bonding effect. Through the brushing method, the glue (or treatment agent) is in more complete contact with the upper processing area (because the brushing process presses the glue on the upper processing area), thereby improving the gluing effect between the upper and the outsole, and enhancing the overall quality and stability of the shoes.

[0017] Since glue and treatment agent are both organic polymer substances, the traditional process requires the reciprocating rotation of the robot arm, and only organic polymer hoses can be used for pipelines. Therefore, it is difficult to solve the corrosion and blockage of the pipeline by the glue and treatment agent. However, in the method described in the present invention, since the supply of glue and treatment agent is non-injection, there is no need for complex rotation and movement like the robot arm, so corrosion-resistant metal hard pipes can be used to effectively solve the corrosion and blockage problems.

DETAILED DESCRIPTION

[0019] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0020] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0021] As mentioned in the background technology, the upper processing automation equipment currently used in the market usually tightly combines the upper with the shoe last, and then uses a precise robot to move the shoe last and the upper as a whole to a designated polishing area. After polishing, the robot moves the shoe last and the upper to the glue spraying area for gluing. This process seems efficient, but it faces many challenges in actual operation.

[0022] During the grinding process, the upper material will produce a lot of powdery debris. These powders not only pollute the working environment, but also easily penetrate into the transmission mechanism of the robot and the gaps of the driving components, resulting in transmission obstruction, equipment performance degradation, and even malfunction. Although the entire equipment can be covered by a box, the robot and other equipment are all located in the box.

[0023] In the glue spraying process, the glue (or treatment agent) is transported to the nozzle of the robot through a flexible hose (the reason for using a hose is that the robot needs to move and flip during spraying, so an organic polymer hose is used to avoid affecting the movement of the robot) and sprayed out in a mist form to cover the area to be processed on the upper. However, the mist glue (or treatment agent) is highly corrosive. Once it adheres to the gap between the hose or the driving parts of the robot, it will cause corrosion damage to these parts, seriously affecting the service life of the equipment. At the same time, because the glue (or treatment agent) is corrosive to the pipeline (because the glue and treatment agent contain polymer materials, and the hose is also formed of polymer materials, the glue or treatment agent will corrode the pipeline), it is also very easy to cause blockage at the nozzle, seriously affecting the production efficiency of the equipment.

[0024] In order to deal with the negative impact of powder and glue (or treatment agent) on the equipment, operators have to perform tedious cleaning work regularly. This not only increases the labor intensity of operators, but also needs to be done when the equipment is shut down, which seriously affects the continuity and efficiency of the production line.

[0025] Based on the above reasons, the present invention provides a method for processing a shoe upper, such as Figure 1 As shown, the method comprises the following steps: Step S100, combining the upper with the shoe last; Step S200, sending the to-be-processed area of ​​the upper into a processing box through a shoe last, and then sealing the processing box; the to-be-processed area is the area where the upper contacts the outsole; Step S300, rotating the workpiece in the box cover to process the area to be processed.

[0026] In step S300, the workpiece is a grinding wheel or a rubber brush surrounding and contacting the area to be processed; When the workpiece is a grinding wheel, the processing is grinding the area to be processed; When the workpiece is a glue brush, the processing is to brush glue on the area to be processed.

[0027] Through the above technical features, the grinding or brushing of the upper processing area or the brushing of the treatment agent can be concentrated in a closed box, which effectively avoids the influence of the powder generated during grinding on other equipment (such as manipulators, drive motors, etc.), and also prevents the corrosion of glue (or treatment agent) to other equipment, thereby improving the cleanliness of the production environment and the service life of the equipment. Compared with the traditional spraying method, the brushing method has a better bonding effect. By brushing, the glue or treatment agent is in more complete contact with the upper processing area (because the brushing process presses the glue or treatment agent on the upper processing area), thereby improving the gluing effect between the upper and the outsole, and enhancing the overall quality and stability of the shoe.

[0028] In one embodiment, the driving member of the working piece is located outside the processing box. The driving member is arranged outside the processing box, which can effectively avoid the influence of powder or glue on the driving member. Optionally, the driving member can be a motor that drives the working piece to rotate or a motor equipped with a reducer, or other equipment that can drive the working piece to rotate.

[0029] In one embodiment, the driving member of the working member is installed in a processing box, and a driving member protection box is installed in the processing box; the driving member is independently sealed and protected by the protection box to prevent the driving member from being affected by powder, glue or treatment agent; and placing the driving member in the processing box can make the overall structure more compact.

[0030] In order to facilitate the entry and closed processing box of shoe lasts, such as Figure 2-Figure 4 and Figure 6 As shown, in one embodiment, the processing box 100 has an opening for facilitating the entry and exit of the shoe last, and a box cover 200 is installed at the opening to achieve the sealing of the processing box.

[0031] For example, Figure 3 and Figure 6 As shown, the box cover 200 is composed of two cover plates 201, which can be opened by opening horizontally, rotating, or opening in opposite directions; the inner edges of the two cover plates 201 have a fitting arc surface 2011, which can fit with the upper 400 combined with the shoe last 300.

[0032] Alternatively, the box cover may also be a rotary cover, a split cover, or other cover forms. The above technical features can facilitate the entry and exit of the shoe last combined with the upper, and the cover plate and the upper are fitted with an arc surface to achieve airtightness, thereby preventing the powder, glue or treatment agent in the treatment box from overflowing.

[0033] In order to achieve the application of glue or treatment agent to the processing area, in one embodiment, when the processing is to apply glue (or treatment agent) to the upper processing area, the glue brush is soaked with glue (or treatment agent), or the processing box contains glue (or treatment agent) in contact with the glue brush. This technical feature can improve the glue application efficiency and make the glue application more uniform.

[0034] In one embodiment, the grinding wheel is composed of a plurality of unit grinding wheels, for example, Figure 3 and Figure 4 As shown, the grinding wheel is composed of a plurality of unit grinding wheels; at the same time, in order to facilitate the rotation of the grinding wheel, the grinding wheel can be used as follows Figure 7 The unit grinding wheels 500 shown are formed, and an arc-shaped grinding surface adapted to (fitting) a part of the upper area to be processed is opened on the unit grinding wheel. The arc-shaped grinding surfaces of multiple unit grinding wheels are combined to form an arc-shaped surface of the area to be processed. When the unit grinding wheel rotates, the arc-shaped grinding surface can better grind the area to be processed and comprehensively cover the area to be processed.

[0035] In one embodiment, the rubber brush is composed of a plurality of unit brushes 600, for example, Figure 8As shown, the unit brush has a power shaft, which is connected to a driving member, and a number of long bristles are installed on the power shaft. The long bristles can better adapt to the arc surface of the area to be processed. When the arc surface of the area to be processed is concave, the glue is brushed through the end of the long bristles. When the arc surface of the area to be processed is convex, the glue (or treatment agent) is brushed through the middle or middle-rear part of the long bristles. The technical feature can make the glue brushing effect of the area to be processed better and adapt to the areas to be processed with different arc surfaces; the form of brushing glue (or brushing treatment agent) has a better bonding effect than traditional spraying glue. Through the form of brushing, the contact between the glue and the area to be processed of the upper is more sufficient (because the brushing process is to press the glue on the area to be processed of the upper), thereby improving the gluing effect between the upper and the outsole, and enhancing the overall quality and stability of the shoe.

Various modifications to these embodiments will be apparent to one 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 will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
