[0001] This application is a divisional application of the application filed on September 16, 2020, with application number 202080057992.5 and invention title "Polishing System for Footwear". Technical Field

[0002] This article relates to systems and methods for polishing footwear components during manufacturing. Background Technology

[0003] Polishing is a process of conditioning the surface of an article through mechanical engagement with it. It is used to polish components that form at least a portion of footwear articles (such as shoes) to improve surface appearance, future manufacturing processes (e.g., better adhesion of paints, dyes, materials, adhesives), and / or dimensions. Polishing is traditionally a labor-intensive process. Summary of the Invention

[0004] Various aspects of this document provide a system for polishing components forming footwear articles. The system includes various discrete modules for effectively polishing different surfaces of the component. In an exemplary aspect, the component is the sole portion of a footwear article. The system includes a vision system that effectively captures the component and helps determine the available operation, position, and / or dimensions of other modules of the system. The system also includes a sidewall polishing module for effectively polishing the sidewalls of the component. The system includes an upper surface polishing module that effectively polishes the surfaces of the component exposed upwards in the system. For example, a sole component may be processed in the system such that the surface processed in the system that would be the ground-facing surface of the sole component when in a wearing configuration is the upper surface as the sole component passes through the system. The system also includes a lower surface polishing module for effectively polishing the lower surface of the component (i.e., the surface opposite the upper surface). The system may also include one or more transport mechanisms for effectively conveying the component through the system. Furthermore, it is conceivable that the system may have two (or more) lines, each line serving a portion of a paired footwear component (e.g., the right sole on a first processing line of the system and the left sole on a second processing line of the system).

[0005] This paper also envisions a method for polishing footwear components using a polishing system. The method includes polishing the sidewalls of the component (such as the sole portion) using a sidewall polishing module of the system. The method also includes polishing the upper surface of the component using a brush from an upper surface polishing module. The brush of the upper polishing module rotates along a first portion of the upper surface in a first direction, and the brush rotates along a second portion of the upper surface in an opposing second direction. The method further includes transferring the component from the upper surface polishing module to a lower surface polishing module. The method includes polishing the lower surface of the component at the lower surface polishing module using a brush and a compression member.

[0027] This document provides apparatus, systems, and / or methods for polishing components of footwear products. Polishing is a mechanical process that alters the surface of a product. This alteration can result from surface removal or buffing. Footwear components can be polished to achieve a desired appearance or surface finish. Footwear components can be polished to remove manufacturing residues such as mold release agents, oils, surface contaminants, residual molding materials, etc. For example, the sole of a footwear product may be molded from a foamed polymer composition and then polished on one or more surfaces to achieve a suitable finish. The polymer composition may include ethylene to vinyl acetate (“EVA”), polyurethane (“PU”), silicone, etc. The polishing operation may occur during anticipated subsequent manufacturing operations such as coloring, adhesive application, molding, etc.

[0028] Polishing is achieved through physical contact between a polishing surface and the part to be polished, causing material abrasion on the surface of the part. The polishing surface can be a brush-like (hereinafter referred to as a "brush") element comprising multiple bristles positioned to interact with the surface of the part to be polished. The brush element can move relative to the surface of the part to be polished, the surface of the part to be polished can move relative to the brush element, or a combination of both the brush element and the surface of the part to be polished can move. Movement of the brush element includes movement of the brush as a whole relative to the surface of the part to be polished in the X, Y, and / or Z directions. Movement of the brush element also includes rotational movement of the brush about the X, Y, and / or Z axes (e.g., rotation or turning of the brush). Movement of the brush element also includes a combination of movement of the brush as a whole in the X, Y, and / or Z directions and rotation of the brush about one or more of the X, Y, and / or Z axes.

[0029] Polishing can also be accomplished by effectively altering the surface of footwear components through additional mechanisms. For example, polishing can be achieved by blasting a medium (e.g., media blasting). The medium can be any combination, such as dry ice (CO2 in solid form), baking soda (sodium bicarbonate), salt (sodium chloride), sand, etc. In these examples, pressure (such as compressed air) is used to blast the medium onto the component surface to abrade it. However, in some instances, media polishing results in residual medium being trapped in the component, additional costs associated with acquiring or cleaning the medium, and environmental pollution caused by the airborne distribution of the medium. Accordingly, some aspects envisioned herein rely on the mechanical interaction between the polishing surface (e.g., bristles on a brush) and the component instead of media abrasion.

[0030] Because footwear components can have complex curves and shapes, various polishing modules are envisioned, each uniquely configured to address the shape of the footwear component (such as the sole). In an exemplary aspect, the system envisions a first module configured to polish the sidewall surfaces of the component. For sole components, the sidewalls form various concave (e.g., midfoot region) and convex (toe and heel ends) curves, which presents a challenge for consistent polishing in a non-automatic manner. The system also envisions an upper surface polishing module configured to polish the upward-facing surfaces of the component as it passes through the system. As will be depicted herein, the upward-facing surfaces of the component can be the expected ground-facing surfaces of the footwear when in a wearing condition. Because the component is supported from below in the upper surface module, a series of clamps configured to hold the first portion of the component can clamp it while a second portion is polished, and the module can clamp the second portion of the component while the first portion is polished. As will be discussed, the direction of brush movement and / or rotation can be varied for the first and second portions to achieve the desired polishing result. In an exemplary aspect, the system also envisions a lower surface polishing module configured to polish the downward-facing surface of a component. The downward-facing surface in the envisioned system can be the foot-facing surface of the sole component when in a wearing orientation. The downward-facing surface of the sole can have a complex curve caused by sidewall portions extending from the downward-facing surface toward the polishing device. Accordingly, to effectively polish the downward-facing surface of the sole component, the bristles extend through the length of the sidewalls to effectively contact the downward-facing surface (e.g., the foot-facing surface of the sole when in a wearing configuration). As will be discussed, this can be accomplished using downward pressure from a top plate and a series of support rollers on either side of the brush with bristles extending above a support plane defined by the series / multiple support rollers. Additional configurations and combinations are envisioned in conjunction with the system.

[0031] Turn to the attached diagram and then turn specifically. Figure 1 , Figure 1 An example of a system 100 for polishing components of footwear articles according to exemplary aspects thereof is depicted. System 100 includes multiple modules with different intended functions. Figure 1 Vision module 102, sidewall polishing module 104, upper surface polishing module 106, and lower surface polishing module 108 are conceived and described. It should be understood that any of the modules can be arranged in an alternative order or sequence. Additionally, it is conceivable that one or more modules can be completely omitted. In one aspect, when vision module 102 is included, its direction of component flow ( Figure 1Located ahead of one or more polishing modules in the Y-axis direction, the vision module effectively identifies the part, part location, part orientation and / or part size, and can then control or assist one or more polishing modules in polishing the part.

[0032] Vision module 102 includes vision system 114 and computing device 112. Computing device 112 includes one or more processors, memory, and other components known in the art, which allow the computing device to convert images captured by vision system 114 into usable information to identify parts, part locations, part orientations, and / or part dimensions, and to provide instructions to one or more polishing modules to properly polish the parts. Wired or wireless logical connections may connect computing device 112 to one or more elements of system 100 (e.g., vision system 114) and / or one or more modules of system 100 to transmit information (e.g., data, instructions).

[0033] The vision system 114 includes an image detection device. Examples of image detection devices include, but are not limited to, a camera. A camera can effectively capture images in the visible spectrum, ultraviolet (UV) spectrum, infrared (IR) spectrum, grayscale, and color scales, as two-dimensional images, as three-dimensional images, as still images, and / or as moving images (e.g., video). The vision system 114 may include one or more light sources, such as those used in [the system]. Figure 6 As depicted in the diagram. The vision system 114 can be calibrated and / or capture a calibration object to help the vision system 114 and / or computing device 112 determine the size, location, orientation, and / or identity of a part. The determined size, location, and / or orientation of the part relative to a known position of the system 100 allows the system 100 to transfer the part to one or more modules with known positioning, location, and / or orientation for subsequent operations.

[0034] The sidewall polishing module 104 includes a first polishing mechanism 128 having a first brush 130 having a cylindrical shape and a plurality of bristles extending outward from a rotation axis 134 of the first brush 130. The brush used herein is an instrument having a central core with bristles extending outward from the core. An example of a brush is a cylindrical core with bristles extending outward around its entire circumference. This brush configuration forms a cylindrical polishing tool capable of rotating about a rotation axis, thereby exposing the bristles to the common surface to be polished throughout the rotation. Alternative arrangements of the bristles and / or core are also contemplated.

[0035] Brush bristles can be formed from a variety of materials. Typically, bristles are a section of material with varying levels of hardness. When viewed in a plane perpendicular to the longitudinal length of the bristles, they can also have various cross-sectional shapes. These cross-sectional shapes can be circular, square, oval, irregular, straight, triangular, etc. The cross-sectional shape can affect the polishing properties of the brush. The material forming the bristles can also be adjusted. Examples of bristles include organic-based materials (e.g., hair, fur, feathers, plant-based), metals (e.g., brass, bronze, steel), and / or polymers (e.g., nylon, polypropylene). The length of the bristles extending from the core can also be adjusted to change the polishing outcome of the brush. It is conceivable that any of the bristle configurations (e.g., material, size, shape) envisioned herein can be applied to any of the brushes also provided herein.

[0036] A first brush 130 includes a plurality of bristles extending outward from a core, through which a rotation shaft 134 extends. The plurality of bristles form a diameter 136 of the first brush 130. The diameter 136 is between 100 mm and 180 mm. This range allows for an effective surface speed at the proposed rotational speed (e.g., 500 to 1,500 RPM, discussed below) to bring the brush surface into contact with the part to be polished. In one exemplary aspect, the diameter 136 is between 120 mm and 160 mm. In another exemplary aspect, the diameter 136 is between 140 mm and 150 mm.

[0037] The first polishing mechanism 128 also includes a first brush rotary driver 132. The first brush rotary driver 132 may be a direct drive mechanism directly connected to the first brush 130, as depicted. Alternatively, the first brush rotary driver 132 may be remotely coupled via one or more transmission couplings (e.g., belts, chains, gears). The first brush rotary driver 132 may be an electric motor, a hydraulic motor, or other mechanical actuator that converts energy into rotational energy. The first brush rotary driver 132 may have a variable speed at which it can operate. Those speeds associated with the first brush 130 are from 500 RPM to 3000 RPM. In yet another example, the envisioned rotational speed provided by the first brush rotary driver 132 is in the range of 1000 to 2400 RPM. In yet another example, the envisioned rotational speed of the first brush rotary driver 132 is from 1400 to 2200 RPM. These envisioned rotational rates, associated with the brush sizes provided herein (e.g., 100 mm to 180 mm), provide the desired surface polishing for the envisioned component composition (e.g., EVA). As will be discussed below, it is envisioned that the brush rotational speed can vary along different portions of the component to be polished. This variation in rotational speed is related to the rate of movement (non-rotation) of the brush as a whole relative to the component, which will be discussed in more detail below. The speed of the first brush rotation driver 132 can be controlled by a computing device such as computing device 112.

[0038] In addition to adjusting the rotational speed of the first brush 130 at different positions relative to the component, it is also conceivable that the angle of the rotation axis 134 can be adjusted, as described below. Figure 8B As depicted. This adjustable approach angle between the first brush 130 and the component allows the brush to better conform to the complex geometry of the component being polished. Therefore, the angle of the rotation axis 134 can be adjusted according to the position of the component relative to the brush.

[0039] Furthermore, it is conceivable that the depth of brush offset can vary based on the relative position of the brush and the component. For example, the first brush 130 may have interaction, with approximately 7 mm to 14 mm of bristles interacting with the component. Specifically, it is conceivable that in a first position, 12 to 14 mm of bristles of the first brush 130 overlap (e.g., engage) with the component, but in another position, 7 to 9 mm of bristles of the first brush 130 overlap with the component. Additionally, as... Figure 7As best depicted, the first footwear component retainer moving mechanism is rotatable during the polishing operation of the sidewall. The rotational rate of the first footwear component retainer moving mechanism can vary based on the relative position between the first brush 130 and the component. In an example, the rotational speed of the first footwear component retainer moving mechanism can be in the range of 22 to 31 revolutions per minute (RPM). For example, based on the surface being polished, in a first relative position between the first brush 130 and the component, the first footwear component retainer moving mechanism can rotate at 22 to 23 RPM, and in a second position, the first footwear component retainer moving mechanism can rotate at 29 to 31 RPM.

[0040] The sidewall polishing module 104 includes a first footwear component retainer 116. The first footwear component retainer 116 includes a heel support 118, a midfoot support 120, and a toe support 122. Gaps exist between the various supports of the first footwear component retainer 116. A first gap 124 and a second gap 126 are depicted. It is conceivable that any number of gaps of any size and / or position can be implemented. The gaps provide a first advantage because they allow for individual adjustment of the support portions. For example, the gaps allow for independent hinged and movement of different support portions when the style, size, and / or shape of the supported footwear component changes. Each support portion can be supported by a support element (e.g., a threaded element, a friction locking element, a pin, a notch) with adjustable characteristics that allow for changes in the height and relative position of the support portion. Another advantage of the gaps will be discussed below. Figure 5 The description is more detailed, which allows the transfer mechanism to store and retrieve the parts to be polished on the first footwear component holder 116.

[0041] In one aspect, the first footwear component retainer 116 is movable. For example, the first footwear component retainer 116 can be moved in the X, Y, and / or Z directions by one or more moving mechanisms (e.g., actuators). The first footwear component retainer 116 can also be rotated about the X, Y, and / or Z axes by one or more moving mechanisms. Accordingly, it is conceivable that the first footwear component retainer 116 can be moved in the X, Y, and / or Z directions, and the first brush 130 can also be moved (and angularly adjustable) in the X, Y, and / or Z directions. The movement of both the first footwear component retainer 116 and the first brush 130 allows for faster throughput and greater flexibility when polishing complex shapes of footwear components. The movement of the first footwear component retainer 116 can be controlled by a computing device such as computing device 112.

[0042] If in Figure 7As depicted in Figure 8, the sidewall polishing module 104 also includes one or more clamping members that effectively secure the component to be polished to the first footwear component retainer 116. In an exemplary aspect, the clamping members utilize the first footwear component retainer 116 to compress the footwear component.

[0043] The upper surface polishing module 106 includes a second brush 140 having a cylindrical shape and a plurality of bristles extending outward from a rotation axis 142. The second brush 140 has a diameter 146 because the bristles extend outward from a core through which the rotation axis 142 extends. The diameter 146 is between 100 mm and 180 mm. This range allows for an effective surface speed at the proposed rotational speed (e.g., 500 to 3,000 RPM) to bring the brush surface against the part to be polished. In one exemplary aspect, the diameter 146 is between 120 mm and 160 mm. In another exemplary aspect, the diameter 146 is between 140 mm and 150 mm.

[0044] The second polishing mechanism also includes a second brush rotary driver 144. The second brush rotary driver 144 can be a direct drive mechanism directly connected to the second brush 140, as depicted. Alternatively, the second brush rotary driver 144 can be remotely coupled via one or more transmission couplings (e.g., belts, chains, gears). The second brush rotary driver 144 can be an electric motor, a hydraulic motor, or other mechanical actuator that converts energy into rotational energy. The second brush rotary driver 144 can have variable speeds at which it can operate. Those speeds associated with the second brush 140 are from 500 RPM to 1500 RPM. In yet another example, the envisioned rotational speed provided by the second brush rotary driver 144 is in the range of 700 to 1400 RPM. In yet another example, the envisioned rotational speed of the second brush rotary driver 144 is from 900 to 1300 RPM. These envisioned rotational speeds, associated with brush sizes (e.g., 100 mm to 180 mm) provided herein, provide the desired surface polishing for envisioned component compositions (e.g., EVA). As will be discussed below, it is conceivable that the brush rotation speed can vary along different parts of the part to be polished. This variation in rotation speed is related to the rate of movement (non-rotation) of the brush as a whole relative to the part, which will be discussed in more detail below. The speed of the second brush rotation driver 144 can be controlled by a computing device such as computing device 112.

[0045] The rotation axis 142 extends in a direction perpendicular to the rotation axis 134 of the sidewall polishing module 104. This alternative direction of the rotation axis reduces throughput time because it allows for linear contact between the brush and the component on the upper surface, rather than rotational contact. In other words, the brush's rotation axis is parallel to the plane that typically extends from the surface to be polished, allowing for higher system throughput and producing the desired polishing results.

[0046] The upper surface polishing module 106 also includes a second footwear component holder 138. The second footwear component holder 138 is similar in features to those already discussed with respect to the first footwear component holder 116. In one aspect, the second footwear component holder 138 is movable. For example, the second footwear component holder 138 can be moved in the X, Y, and / or Z directions by one or more moving mechanisms (e.g., actuators). The second footwear component holder 138 can also be rotated about the X, Y, and / or Z axes by one or more moving mechanisms. Accordingly, it is conceivable that the second footwear component holder 138 can be moved in the X, Y, and / or Z directions, and the second brush 140 can also be moved in the X, Y, and / or Z directions. The movement of both the second footwear component holder 138 and the second brush 140 allows for faster throughput and greater flexibility when polishing complex shapes of footwear components. The movement of the second footwear component holder 138 can be controlled by a computing device such as computing device 112.

[0047] If in Figures 9 to 11 As illustrated in more detail, the upper surface polishing module additionally includes one or more clamping members that selectively clamp the component to the second footwear component retainer 138.

[0048] The lower surface polishing module 108 includes a third brush 152 having a cylindrical shape and a plurality of bristles extending outward from a rotation axis 154. The third brush 152 has a diameter 156 because the bristles extend outward from a core through which the rotation axis 154 extends. The diameter 156 is between 100 mm and 180 mm. This range allows for an effective surface speed at the proposed rotational speed (e.g., 500 to 1,500 RPM) to bring the brush surface against the part to be polished. In one exemplary aspect, the diameter 156 is between 120 mm and 160 mm. In another exemplary aspect, the diameter 156 is between 152 mm and 150 mm.

[0049] The third polishing mechanism also includes a third brush rotary driver (not shown). The third brush rotary driver can be a direct drive mechanism directly connected to the third brush 152, as depicted. Alternatively, the third brush rotary driver can be remotely connected via one or more transmission couplings (e.g., belts, chains, gears). The third brush rotary driver can be an electric motor, a hydraulic motor, or other mechanical actuator that converts energy into rotational energy. The third brush rotary driver can have a variable speed at which it can operate. Those speeds associated with the third brush 152 are from 500 RPM to 3000 RPM. In yet another example, the envisioned rotational rate provided by the third brush rotary driver is in the range of 700 to 1520 RPM. In yet another example, the envisioned rotational rate of the third brush rotary driver is from 900 to 1300 RPM. These envisioned rotational rates, associated with brush sizes (e.g., 100 mm to 180 mm) provided herein, provide the desired surface polishing for envisioned component compositions (e.g., EVA). As will be discussed below, it is conceivable that the brush rotation speed can vary along different parts of the part to be polished. This variation in rotation speed is related to the rate of movement (non-rotation) of the brush as a whole relative to the part, which will be discussed in more detail below. The speed of the third brush rotation drive can be controlled by a computing device such as computing device 112.

[0050] The rotation axis 154 extends in a direction perpendicular to the rotation axis 134 of the sidewall polishing module 104. This alternative direction of the rotation axis reduces throughput time because linear contact, rather than rotational contact, can be maintained between the brush and the part on the lower surface. In other words, the rotation axis of the third brush 152 is parallel to the plane that the surface to be polished typically extends, which allows the system to have higher throughput and produce the desired polishing results.

[0051] The lower surface polishing module 108 also includes a series of rollers 148, 150. The rollers form a support surface defining a support plane 110 over which footwear components pass during the lower surface polishing operation. The rollers can be free-rolling or they can be powered. For example, the rollers can rotate freely in response to the movement of footwear components on the rollers. Alternatively, the rollers can rotate in response to a drive source (such as an actuator) to help move the footwear components through the lower surface polishing module 108. Each of the rollers includes a rotation axis parallel to a rotation axis 154. The support plane 110 defined by the rollers 148, 150 can be used as a reference plane for the elements of the lower surface polishing module 108. For example, the rotation axis 154 is below the support plane 110. The bristles of a third brush 152 extend above the support plane 110 to effectively engage the lower surface of the footwear component being polished. A pressure plate 158 (discussed immediately below) is located above the support plane 110. The positioning of various components relative to the support plane 110 allows the system 100 to effectively and as intended polish the footwear components.

[0052] The lower surface polishing module 108 also includes a pressure plate 158. The pressure plate 158 is effectively movable in at least the Y and Z directions. The movement of the pressure plate 158 is accomplished using one or more actuators, which may be controlled by a computing device such as computing device 112. Movement in the Z direction allows the pressure plate 159 to press the footwear component against rollers 148, 150 and the third brush 152. This compression allows the third brush 152 to effectively polish the lower surface of the footwear component. The pressure plate 158 has a component contact surface 160, which can be textured to enhance the adhesion between the pressure plate 158 and the footwear component as the footwear component moves relative to the third brush 152 via the pressure plate 158.

[0053] Although Figure 1 The image depicts a single processing line of system 100, but it is conceivable that two or more lines can operate in system 100. For example, a first line and a replicated second line can operate in parallel to polish a right shoe component and a left shoe component. The first line has a shoe component holder configured to support the "right" shoe component, and the second line has a shoe component holder configured to support the "left" shoe component.

[0054] Although not depicted, it is conceivable that one or more logical connections exist between the components / elements of the depicted system 100. For example, wired and / or wireless connections may exist between any components / elements of system 100 to effectively communicate and control the polishing operation. Logical connections allow system 100 to adjust one or more parameters (e.g., brush position, brush position transition speed, support position, support speed, conveying speed, rotational speed, rotational direction, timing, clamping position, clamping activation).

[0055] Furthermore, it is conceivable that one or more conveying mechanisms may be included in parts of system 100 to convey footwear components to and from modules of system 100. This will be discussed in conjunction with... Figure 5 Exemplary transmission mechanisms are discussed.

[0056] It is conceivable that one or more components / parts / modules of system 100 may be omitted. It is also conceivable that one or more components / parts / modules of system 100 may be arranged in alternative relative positions. It is conceivable that system 100 may include additional components / parts / modules.

[0057] Figure 2 An exemplary footwear article 200 is depicted according to various aspects thereof. Footwear article 200 includes an upper 202 and a sole 204. The sole 204 has sidewalls 206 and a ground-facing surface 208. The sole 204 also has a sidewall adjacent to the upper 202 and... Figure 2 The unnumbered surface facing the foot is opposite to surface 208 facing the ground. Although athletic shoes are depicted, it is conceivable that footwear can be any style of footwear, such as sandals, slippers, boots, dress shoes, etc.

[0058] The sole 204 can be a monolithic sole formed of a homogeneous material. The sole 204 can be a combination of an outsole and a midsole, wherein the outsole forms at least a portion of the ground-facing surface 208, and the midsole forms at least a portion of the foot-facing surface. The sole 204 may include additional elements such as air pockets (e.g., air bladders) and mechanical impact damping devices (e.g., compression springs). The sole 204 can be formed from various materials, such as EVA, PU, ​​silicone, polypropylene, etc. In an exemplary aspect, the sole 204 is at least partially formed from injected and foamed EVA, which is then polished prior to final formation according to the concepts provided herein. In yet another example, the sole 204 is at least partially formed from injected and foamed EVA, which is in its final shape prior to polishing according to the concepts provided herein.

View 300 includes reference numerals A to H, which are for reference only and are not actually included in the ground-facing surface 208. Reference numerals A 302, B 304, C 306, D 308, E 310, F 312, G 314, and H 316 are provided. Reference numeral A 302 is located at... Figure 2The heel end of the footwear 200 has reference mark E 310 located at the toe, reference mark C 306 located on the outer side, and reference mark G 314 located on the inner side. Additional specific reference marks are also depicted, such as reference mark I 318, reference mark J 320, reference mark K 322, reference mark L 324, reference mark M 326, and reference mark N 328. Each reference point can be referenced based on the angular position of the sole 204 relative to a center point. In an example, reference mark C 306 may represent 0 degrees (or 360 degrees), and each point in a clockwise direction is relative to reference mark C 306. For example, reference mark E 310 is 90 degrees, reference mark G 314 is 180 degrees, and reference mark A 302 is 270 degrees. Continuing this example, reference mark I 318 is approximately 10 degrees, reference mark J 320 is approximately 60 degrees, reference mark K 322 is approximately 100 degrees, reference mark L 324 is approximately 120 degrees, reference mark M 326 is approximately 200 degrees, and reference mark N 328 is approximately 210 degrees. Specific sections between reference marks I 318 and J 320, between reference marks K 322 and L 324, and between reference marks M 326 and N 328 will be discussed below. In this example, each of these specific sections provides the advantage of adjusting one or more polishing variables to achieve the desired polishing result given the geometry of the sole 204 at each of these sections. As will be provided below, Figure 1 Some operations of the system 100 respond to the location where the polishing operation occurs by operating at different movement speeds, rotation speeds, brush angles, and rotation directions. In those instances, for illustrative purposes, [the following will be shown]. Figure 3 The reference marker is used as an instance reference.

[0060] Figure 4 A top plan view of an exemplary footwear component retainer 400 according to various aspects thereof is depicted. Footwear component retainer 400 is... Figure 1 Enlarged plan view of the elements discussed in relation to the first footwear component retainer 116. As previously indicated, it is conceivable that the footwear component retainer 400 can have any number of supports of any size / shape.

[0061] The heel support 118, midfoot support 120, and toe support 122 can be formed of any material. In various respects, the supports are formed of polymeric or metallic materials. The size, shape, orientation, and spacing of the supports can vary depending on the footwear component to be polished by the system. Gap 124 and 126 can be adjusted to accommodate different sizes of the footwear component. The adjustment of gap 124 and 126 can be limited such that the supports provide sufficient support for the polishing operation (e.g., the gaps may not increase beyond a size sufficient to maintain the dimensional stability of the footwear component during polishing). The dimensions of the gaps can also be limited such that they are held above the dimensions required for one or more elements of the conveying mechanism to pass through them for storing and / or retrieving the footwear component from the footwear component holder 400.

[0062] Figure 5 It describes various aspects based on this article. Figure 4 A footwear component holder 400 has a conveying mechanism 502 that interacts with it. In this example, the conveying mechanism 502 includes a lower fork having a first fork tooth 504 and a second fork tooth 506 that respectively pass through gaps 124 and 126. The conveying mechanism 502 also includes an upper fork 508. The conveying mechanism 502 is movable in the X, Y, and / or Z directions, and rotates about each of these directions. The lower fork teeth 504, 506 and the upper fork tooth 508 effectively compress the footwear component therebetween to efficiently store, convey, and retrieve the footwear component. The spacing between the first fork tooth 504 and the second fork tooth 506 and the spacing between the first gap 124 and the second gap 126 engage such that both the first fork tooth 504 and the second fork tooth 506 can pass through the respective gaps to store and / or retrieve the footwear component. The compression gripping of the footwear component by the conveying mechanism 502 allows the known position and orientation of the footwear component to be used for storage and positioning at various modules of the system provided herein.

[0063] The transmission mechanism 502 can be used in various ways to... Figure 1 The system moves within 100. Examples include linear actuators, stepper motors, belts, chains, gear drives, etc. Any combination of movement methods can be used to move in the X, Y, and / or Z directions. Furthermore, any combination of movement methods can be used to generate compressive force between the lower fork teeth 504, 506 and the upper fork tooth 508.

[0064] Figure 6 A schematic diagram of a vision system module 600 according to an exemplary aspect of this document is depicted. The vision system module 600 is... Figure 1Enhanced depiction of vision module 102. Vision system module 600 includes computing device 112, vision system 114, first illumination source 602, second illumination source 604, footwear component holder 606, conveying mechanism 502, and sole 204 (depicted in dashed lines for illustrative purposes).

[0065] The footwear component retainer 606 includes a heel support 608, a midfoot support 610, and a toe support 612. The components of the footwear component retainer 606 are similar to... Figure 1 First footwear component retainer 116 and Figure 4 The footwear component retainer 400 has similarly named elements. The lower fork of the conveying mechanism is depicted as having passed through the gap in the footwear component retainer 606 to hold the sole 204 on the footwear component retainer 606. The upper fork 508 is depicted as compressing the sole 204 into the footwear component retainer 606; however, it is conceivable that the upper fork 508 and the conveying mechanism 502 can be moved together from the field of view of the vision system 114 in various ways.

[0066] The first illumination source 602 and the second illumination source 604 can be any suitable illumination source for the vision system 114 (e.g., UV light emission, IR light emission, visible spectrum emission). Furthermore, although depicted on the upper surface of the sole 204 (i.e., Figure 2 The light source is located below the ground-facing surface 208, but it is conceivable that one or more light sources could be above the sole 204. The location of the light source below the upper surface (i.e., the surface captured by the vision system 114) allows for the generation of contrast in the sole 204. In the absence of additional illumination from the light source on the upper surface, the periphery of the sole 204 will generate an luminous contrast relative to the additional illumination from the light source below the sole 204. This contrast provides enhanced shape detection through the vision system 114. Although two discrete light sources are depicted, it is conceivable that any number of light sources can be implemented at any location.

[0067] The vision system module 600 is envisioned to capture one or more images of the sole 204 to identify one or more characteristics of the sole 204. Characteristics may include, but are not limited to, size, shape, style, position, orientation, identification code (e.g., barcode), etc. Figure 1 The system 100 can use the determined characteristics to control Figure 1 The system 100 is used for polishing and general operation. For example, it can guide the conveying mechanism to grip footwear components from the footwear component holder 606 to a specific location so that the footwear components are properly positioned at the future footwear component holder. The system can also use determinations from the vision system module 600 to determine parameters (e.g., position, speed, direction, pressure) for future polishing operations at different modules of the system.

[0068] Although Figure 6 A specific arrangement of elements and components is described, but it is conceivable that any combination of components can be used. Additionally, it is conceivable that additional elements and components can be integrated with the vision system module 600.

[0069] Figure 7 , Figure 8A and Figure 8B It describes the various aspects from this article. Figure 1 An enhanced view of the sidewall polishing module 104. Figure 7 A top plan view of the sidewall polishing module 700 according to various aspects of this document is depicted. As indicated above, the sidewall polishing module 700 is combined with... Figure 1 An enhanced view of the features discussed in the sidewall polishing module 104. Figure 7 The first brush moving mechanism 708 is also depicted. The first brush moving mechanism is configured to move the first brush 130 in the X, Y, and / or Z directions. The first brush moving mechanism is also configured to move the first brush 130 at various angles relative to one or more elements, as described below. Figure 8B As depicted. The first brush moving mechanism 708 is operated by actuation, such as an electric actuator and / or a pneumatic actuator, to adjust the position of the first brush 130. The actuation can be by, for example, an electric actuator and / or a pneumatic actuator. Figure 1 The computing device 112 is controlled by the computing device. The first brush moving mechanism 708 can move the first brush 130, thereby applying pressure to footwear components (such as...) at a desired angle. Figure 2 The expected force is applied to the sidewall of the shoe sole (204).

[0070] The anticipated force can be described by the amount of brush depth interacting with the component. This level of interaction can be expressed as a depth offset. The depth offset is the amount of brush bristles or brush overlapping the component, measured from the distal end of the bristles. The depth offset can be any amount, but it is envisioned to be approximately 10 mm at some locations relative to the component's first brush 130. At other locations, it can be envisioned that the first brush 130 is at... Figure 3 There is a first depth offset (e.g., 12 to 14 mm) between reference mark I 318 and reference mark J 320, and the first brush 130 is in Figure 3 There is a second depth offset (e.g., 7 to 9 mm) between reference mark K 322 and reference mark L 324, and the first brush 130 is in Figure 3 There is a third depth offset (e.g., 10 mm) between reference mark M 326 and reference mark N328. In this example, based on the complex curvature of the footwear at the provided section, the depth offset of the first brush 130 is adjusted to achieve a sufficient polishing result. Alternative depth offsets and positions are envisioned, and they can be implemented independently.

[0071] The sidewall polishing module 700 also includes a first footwear component retainer moving mechanism 702. The first footwear component retainer moving mechanism 702 effectively moves the first footwear component retainer in the X, Y, and / or Z directions and (or alternatively) rotates the first footwear component retainer about the X, Y, and / or Z directions. Figure 1 As depicted, the first footwear component retainer moving mechanism 702 effectively rotates the first footwear retainer about the Z direction. The rotational speed of the first footwear component retainer moving mechanism 702 is variable. Accordingly, it is conceivable that the first footwear component retainer moving mechanism 702 can be directed towards a first portion of the footwear component (e.g., a relatively straight portion of the footwear component, such as in...). Figure 3 Reference mark B 304 and Figure 3 The reference mark D 308 (between) rotates at a first speed, and the first footwear component retainer moving mechanism 702 can target the second part of the footwear component (e.g., the curved portion of the footwear component, such as in...). Figure 3 Reference mark D 308 and Figure 3 The reference mark F 312 rotates at a second speed (e.g., slower than the first speed).

[0072] In a specific instance, it is conceivable that the first footwear component retainer moving mechanism 702 moves in a clockwise manner (e.g., Figure 7 In the "A" direction) at a first rate (e.g., 22 to 23 RPM) Figure 3 The first footwear component retainer moving mechanism 702 rotates between reference mark I 318 and reference mark J 320 at a second rate (e.g., 19 to 20 RPM). Figure 3 The reference mark K 322 rotates between the reference mark L 324, and the first footwear component retainer moving mechanism 702 moves at a third rate (e.g., 29 to 31 RPM). Figure 3 The reference mark M 326 rotates between reference mark N 328. In this example, based on the complex curvature of the footwear article in the provided section, the rotational speed of the first footwear component retainer moving mechanism 702 is adjusted to achieve sufficient polishing results. Alternative rates and positions are envisioned, and they can be implemented independently.

[0073] The direction of rotation of the first footwear component retainer moving mechanism 702 about its axis in the Z direction is also related to the direction of rotation of the first brush 130 about its axis of rotation 134. It is conceivable that the first brush 130 rotates in a first direction (e.g., clockwise), while the first footwear component retainer moving mechanism 702 rotates in the opposite direction (e.g., counterclockwise). This relative rotation has the effect of reducing the speed of interaction between the first brush 130 and the footwear component, and pushing brushed residue to the front portion of the brush. Alternatively, it is conceivable that the first brush 130 rotates in the first direction (e.g., clockwise), and the first footwear component retainer moving mechanism 702 rotates in a common direction. This configuration results in brushed residue from the footwear component being discharged behind the brushed surface, which prevents accidental abrasion from brushed residue to achieve a consistent polish.

[0074] As previously provided, it is conceivable that the first brush 130 can rotate at a variable speed (e.g., 2, 3, 4, 5, 6 or more discrete speeds). This variable rotation speed can be selected to make the number of brush rotations consistent for each part of the footwear component. For example, it is conceivable that the first brush 130 can be targeted at a first part of the footwear component (e.g., a relatively straight portion of the footwear component, such as in…). Figure 3 Reference mark B 304 and Figure 3 The first brush 130 rotates at a first speed between reference marks D 308, and the first brush 130 can target a second part of the footwear component (e.g., a curved portion of the footwear component, such as in...). Figure 3 Reference mark D 308 and Figure 3 The first brush (between reference mark F 312) rotates at a second speed (e.g., slower than the first speed). Therefore, the coordination between the first brush rotation speed, the rotation of the first footwear component retainer moving mechanism 702, and the first brush moving mechanism 708 provides a more uniform and desired polishing result.

[0075] In a specific instance, it can be envisioned that the first brush 130 rotates clockwise (e.g., Figure 7 In the "A" direction) at a first rate (e.g., 1300 to 1500 RPM) Figure 3 Rotating between reference mark I 318 and reference mark J 320, the first brush 130 operates at a second rate (e.g., 2100 to 2300 RPM) on... Figure 3 The reference mark K 322 rotates between the reference mark L 324, and the first brush 130 operates at a third rate (e.g., 1700 to 1900 RPM). Figure 3The reference mark M 326 rotates between reference mark N 328. In this example, based on the complex curvature of the footwear at the provided section, the rotational speed of the first brush 130 is adjusted to achieve sufficient polishing results. Alternative speeds and positions are envisioned, and they can be implemented independently.

[0076] The variability in the speed of the first brush 130, provided by the first brush rotation driver 132, allows for consistent polishing of the sidewalls. Due to the complex curves and non-linear surface of the sole 204, the first brush 130 does not move along the sidewall at a uniform rate. Because the movement of the first brush 130 along the sidewall is inconsistent, a uniform rotational rate of the first brush 130 would result in over-polishing at locations where the first brush 130 traverses the sidewall more slowly and / or under-polishing at locations where the first brush 130 traverses the sidewall more quickly. Accordingly, in some respects, there is a positive correlation between the rate at which the first brush 130 traverses the surface to be polished and the rotational rate of the first brush 130. In other words, when the first brush has a larger rate of movement along the polishing surface of the footwear component, the rotational rate of the first brush is larger relative to the portion of the footwear component where the first brush 130 has a smaller rate of movement. Additionally, the variable rate of brush rotation also allows for variability in the polishing effect produced by the first brush 130. For example, at the location where additional polishing is to be performed (e.g., based on detection by a vision system such as vision module 102), the rotational speed of the first brush 130 can be increased from the standard rate to create a greater number of revolutions of the cylindrical brush in the area identified for additional polishing.

[0077] Figure 8A It describes various aspects based on this article. Figure 7 Side view of the sidewall polishing module 700. The sidewall polishing module 700... Figure 8A The view best illustrates the first clamp 704 and the second clamp 706. Clamps 704 and 706 have clamping surfaces that contact and compress the sole 204 to secure the sole 204 to the first footwear component retainer 116 for polishing operations performed by the first brush 130. Each of the first clamp 704 and the second clamp 706 is independently movable in a first respect. Alternatively, the first clamp 704 and the second clamp 706 can move together. Figure 8AAs depicted, the clamps move linearly along the Z-axis to generate compressive force on the sole 204. A moving mechanism, not depicted but contemplated, moves in coordination with the first footwear component retainer moving mechanism 702. Accordingly, during the polishing operation, as the first footwear component retainer moving mechanism 702 moves the first footwear component retainer 116, the clamps can move and maintain the compressive force on the sole 204. In other words, it is contemplated that the moving mechanisms associated with the first clamp 704 and the second clamp 706 are synchronized with the movement of the first footwear component retainer moving mechanism 702. This synchronized movement allows the footwear component to be repositioned relative to the first brush 130 during the polishing operation while remaining fixed to the first footwear component retainer 116 by the clamps.

[0078] Figure 8B It describes various aspects based on this article. Figure 7 A front view of the sidewall polishing module 700. Specifically depicted is the angular adjustability of the first brush 130, as shown by an alternative position of the first brush 130 as an angled first brush 130A. The angular variability of the first brush 130 at angle 718 allows the sidewall polishing module 700 to better compensate for and regulate the recoil force that can be generated between the bristles of the first brush 130 and the component when a perpendicular intersection occurs between the component (e.g., the sidewall) and the brush bristles. By introducing angle 718, the interaction between the first brush 130 and the component in a non-perpendicular manner allows the bristles of the first brush 130 to convert the force generated between the first brush 130 and the component into a polishing force, rather than the force converted by the first brush 130 (e.g., recoil force). Additionally, angle 718 allows for interaction between more parts of the component that change away from the sidewall portion. Accordingly, in one aspect, transitions between the various modules of the system can be achieved. (Ending with "A") Figure 8B The elements represent angled forms of similar numbered features. For example, an angled first brush 130A is an angled depiction of the first brush 130. Similarly, a rotation axis 134A is an angled depiction of the rotation axis 134.

[0079] Figure 7 , Figure 8A and Figure 8BThe sidewall polishing module 700 is adapted to perform a polishing operation on footwear components (such as sole 204). This operation can be expressed as a series of steps. Initially, the footwear component is compressed between a support surface (e.g., heel support 118, midfoot support 120, toe support 122) and a clamping surface (e.g., first clamp 704, second clamp 706). The process continues to bring the first brush 130 into contact with the footwear component at a first position (e.g., heel end, toe end). The first brush 130 rotates at a first rate while contacting the footwear component at the first position. The footwear component is repositioned relative to the first brush 130, such as by moving back and forth along the sidewall surface. This repositioning can occur by motion generated by the rotation of the first footwear component retainer moving mechanism 702 about an axis of rotation 134 parallel to the first brush 130. Additionally or alternatively, repositioning occurs by linear movement of the first brush 130 by means of the first brush moving mechanism 708. Repositioning allows the first brush 130 to contact the sole 204 at a second location different from the first location. The second location can be the medial or lateral side of the sole 204 in the midfoot region. When the first brush 130 contacts the second location, the first brush 130 rotates at a second rate. This second rotation rate can be a faster rate than the first brush 130. As previously discussed, this could be a result of the first brush 130 traversing the sidewall portion including the second location at a faster rate than the sidewall portion having the first location.

[0080] Figure 9 and Figure 10 It describes the various aspects from this article. Figure 1 An enhanced view of the upper surface polishing module 106. Specifically, Figure 9 The first configuration is described according to various aspects of this article. Figure 1 A front view of the upper surface polishing module 106. A second footwear component retainer 138 is depicted having a sole 204 supported thereon. A first clamp 902 and a second clamp 904 are also depicted. A second brush 140 having a rotation axis 142 is depicted having a second brush moving mechanism 906 that effectively moves the second brush 140 in at least the Z direction; however, in some respects it is also conceivable that the second brush moving mechanism can move the second brush 140 in or around the X, Y, and / or Z directions.

[0081] The first clamp 902 is in Figure 9The first clamp 902 is depicted in a clamping position, while the second clamp 904 is in a released position. The clamping position is the relationship between the clamp and the footwear component retainer, such that compressive force is applied to the footwear component between the clamp and the component retainer to secure the footwear component. In the released position, the clamp and the component retainer (e.g., a support surface) are not positioned relative to each other to apply retaining compressive force to the footwear component. Movement of the first clamp 902 and the second clamp 904 is achieved by a moving mechanism, such as an actuator, which effectively positions the clamps in the clamping or released position. Control of the moving mechanism is achieved by, for example, a... Figure 1 The calculation device 112 performs the calculation. Alternatively, the change between the clamping and releasing positions is achieved by manual operation. The movement of the clamp in the upper surface polishing module can be in the Z direction, but it is also conceivable that the clamp can move / rotate in the X, Y and / or Z directions. The first clamp 902 clamps the heel end of the sole 204, while the second clamp 904 effectively clamps the toe end of the sole 204.

[0082] During the polishing operation, the second brush 140 is repositioned along the upper surface of the sole 204 (the surface 208 facing the ground when in the wearing configuration) to polish the upper surface. This repositioning of the second brush 140 is accomplished by a second brush moving mechanism 906, which effectively moves at least in the Y and Z directions, such as... Figure 9 As depicted. Additionally, it is conceivable that the second brush moving mechanism 906 effectively moves / rotates the second brush 140 along or about the X, Y, and / or Z directions. The second brush moving mechanism 906 operates in conjunction with a moving mechanism (such as an actuator) that operates with controlled speed and position. Speed ​​and / or position control can be achieved by, for example... Figure 1 The computing device indicator of computing device 112.

[0083] The second brush moving mechanism 906 effectively applies force to the sole 204 via the second brush 140. This force can be adjusted to achieve the desired polishing result. In some aspects, the second brush moving mechanism 906 applies a force to the footwear component that creates a pressure of 2 to 3 kg / cm³. In this example, the second brush comprises nylon bristles. In an exemplary aspect, 2 to 3 kg / cm³ 3The pressure applied is the effective amount of pressure required to achieve a sufficient polishing result on the EVA article. This also results in an interaction of approximately 5 mm between the brush bristles and the footwear component. In other words, the second brush 140 is positioned such that the footwear component is approximately 15 mm within the radius of the second brush 140. For example, in an exemplary aspect, if the second brush 140 has a diameter of 145 mm (radius of 72.5 mm), the footwear component is positioned approximately 67.5 mm from the axis of rotation 142 of the second brush 140. It should be understood that any offset distance can be used, and this offset distance will vary based on the material to be polished, the brush material, the desired polishing result, the brush rotation speed, the brush movement speed, etc. It should be understood that any pressure can be applied. It should also be understood that any amount of bristle interaction (e.g., the depth to which the component interaction penetrates the bristles) can be contemplated.

[0084] From a system perspective, the offset distance can be expressed as the distance from the support surface of the second footwear component retainer 138. For example, while the above example describes the distance the footwear component extends into the bristles, the same concept can be expressed from a system perspective, where the same position of the brush can be measured relative to the support surface of the footwear component retainer. In other words, achieving a specific insertion of the known footwear component into the bristles of the brush also results in a known offset of the same brush from the support surface of the footwear component retainer that supports the footwear component.

[0085] like Figure 1 As depicted, the second brush 140 rotates about a rotation axis 142 via a second brush rotation driver 144. The second brush rotation driver 144 effectively rotates in a first direction (e.g., as shown in the image). Figure 9 In the direction of “A” (counterclockwise direction) or in the second direction (e.g., as shown in the image), Figure 9 The second brush 140 rotates in the clockwise direction (as depicted by the direction "B" in the diagram). During the polishing operation on the upper surface, it is conceivable that the second brush 140 rotates in the first direction with respect to the first portion of the upper surface, and the second brush 140 rotates in the second direction with respect to the second portion of the upper surface.

[0086] This variable direction of rotation allows footwear components to be held in place during the polishing process. For example... Figure 9As depicted, a second brush 140 polishes the heel end of the sole 204, while a first clamp 902 secures the heel end of the sole. In this example, the second brush 140 can rotate counterclockwise as it moves from the heel end to the toe. This rotation applies tension to the relatively flexible sole 204. This tension helps hold the sole 204 securely against the support surface of the second footwear component retainer 138. This is in contrast to the compressive force generated by the clockwise rotation of the second brush 140. In some instances, the compressive force can lift the sole 204 from the second footwear component retainer 138, thus reducing the effective hold provided by the first clamp 902. Figure 10 As will be shown, when the second brush 140 moves in the opposite direction from toe to heel, the second brush 140 can rotate clockwise to apply tension to the sole 204. Therefore, it is conceivable that a relationship exists between the direction of travel of the brush and the direction of rotation of the brush. In other words, when the brush moves in the first direction, it rotates counterclockwise, and when the brush moves in the second direction (opposite to the first direction), it rotates clockwise.

[0087] Figure 10 The second configuration is described according to various aspects of this article. Figure 9 A front view of the upper surface polishing module. In this second configuration, the second brush 140 moves from the toe towards the heel. Accordingly, the first clamp 902 is in the released position to prevent obstruction of the second brush 140 from polishing the upper surface. The second clamp 904 is in the clamping position, holding the sole 204 to the support surface of the second footwear component retainer 138. As previously discussed, due to the different travel direction of the second brush 140, in... Figure 10 The second brush 140 can be used in conjunction with it. Figure 9 The rotation direction is different from the rotation direction.

[0088] Additionally or alternatively, the rotation direction can also be adjusted based on the proximity of the second brush 140 to the toe or heel end. Because the first clamp 902 and the second clamp 904 hold the sole 204 in a mid-position relative to the toe and heel ends, the rotational movement of the second brush 140 can remove the sole 204 from the supporting surface during the polishing process, as is done when the portion of the sole 204 extending between the end (e.g., the heel or toe end) and the clamp is polished at the same end. Accordingly, in an exemplary aspect, a change in the rotation direction of those portions extending between the end and the clamping position can have the same alternative rotation direction as the other portions of the upper surface.

[0089] Figure 11 It describes various aspects based on this article. Figure 9A top plan view of the upper surface polishing module. The first clamp 902 and the second clamp 904 are depicted as extending across the width of the sole 204. One or more of the first clamp 902 and the second clamp 904 can be in a clamping or releasing position at a given time. Additionally, although described in this example as movement in the Z direction between the clamping and releasing positions, it is conceivable that the releasing position could result in rotation about different directions or movement in different directions. Additionally, as... Figure 11 As shown, the length of the second brush 140 in the longitudinal direction is at least as wide as the footwear component to be polished. This length allows for a reduction in the number of passes of the second brush 140 over the surface to be polished.

[0090] The upper surface polishing module is configured to perform a polishing operation on the upper surface of the footwear. The polishing operation can be expressed as a series of steps including pressing the footwear component between the support surface of the second footwear component retainer 138 and the clamping surface of the first clamp 902, such as... Figure 9 As depicted. A second brush 140 contacts the sole 204 at a first position, such as the toe of the foot. The second brush 140 rotates in a first direction while contacting the sole 204 at the first position. The first direction of rotation may be counterclockwise in a first instance, or clockwise in a second instance. These steps continue to move the second brush along the surface to be polished. Figure 10 As depicted, the first clamp 902 moves to the released position, while the second clamp 904 moves to the clamping position. The second brush 140 contacts the sole 204 in a second position (e.g., at the heel end) different from the first position. When the second brush 140 is in the second position, it rotates in a second direction. As the second brush 140 rotates in the second direction, it is conveyed along at least a portion of the surface to be polished. In this example, the brush can be conveyed in the first direction when it rotates in the first direction, and it can be conveyed in the second direction when it rotates in the second direction. However, the brush can rotate in both the first and / or second directions while being conveyed in a common direction along the surface of the sole 204.

[0091] Figures 12 to 13 It describes the various aspects from this article. Figure 1 An enhanced view of the lower surface polishing module 108. Specifically, Figure 12 A front view of the lower surface polishing module in the first configuration, according to various aspects of this paper, is depicted. (See attached image.) Figure 12The depicted lower surface polishing module provides a third brush 152 having a rotation axis 154. The third brush 152 includes a plurality of bristles extending outward from the rotation axis 154. The outward extension of the bristles can extend from a core through which the rotation axis 154 extends. The third brush 152 is located between a plurality of rollers forming a footwear component retainer. Rollers 148, 150 are exemplary rollers. Any number of rollers can be combined to form a footwear retainer for the lower surface polishing module. A support plane 1202 is formed by the support surfaces of the plurality of rollers 148, 150.

[0092] like Figure 12 As depicted, the rotation axis 154 is below the support plane 1202, while the bristles of the third brush 152 extend above the support plane 1202. The bristles of the third brush 152 extending above the support plane 1202 are advantageous for the sole 204 and, when in a wearing configuration, polish the foot-facing surface opposite the ground-facing surface of the sole 204. The sole 204 forms a cup-shaped structure, wherein the foot-facing surface is recessed from the distal end of the sidewall. In other words, the sidewall of the sole 204 causes the foot-facing surface of the sole 204 to be offset from the support plane 1202. The extension of the bristles above the support plane 1202 allows the sole 204 to travel along the support plane 1202 while still allowing the bristles to meaningfully engage with the foot-facing surface offset from the support plane 1202 to effectively polish the foot-facing surface of the sole 204. In this example, the amount of bristle extension above the support plane 1202 (e.g., on the side of the support plane 1202 opposite to the axis of rotation 154) can be adjusted based on the offset between the support plane 1202 and the surface facing the foot caused by the sidewall height.

[0093] The rotation direction of the third brush 152 can be counterclockwise (e.g., Figure 12 (in the "A" direction) or in a clockwise manner (e.g., Figure 12 (in the "B" direction). The third brush 152 is rotated by a third brush rotation mechanism, such as an actuator. The third brush rotation mechanism can be connected to the discussed... Figure 1 The second brush rotation driver 144 is similar. The third brush rotation mechanism can be composed of, for example, Figure 1The computing device 112 is controlled by a computing device. The computing device can adjust one or more parameters, such as the rotation direction and speed of the third brush 152. The computing device can adjust the rotation direction, for example, based on the position of the sole 204 or the pressure plate 158. For example, when the pressure plate pushes the sole 204 across the third brush 152, the third brush 152 can rotate in a first direction, such as clockwise, for a portion of the sole 204. For different portions of the sole 204 (e.g., the heel end portion), the third brush 152 can rotate in an opposite direction (e.g., counterclockwise). The third brush 152 can rotate in the first direction more than 50% of the length of the pressure plate 158, which passes the third brush 152 at the rotation axis 154 in the conveying direction. The third brush 152 can rotate in the first direction more than 75% of the length of the pressure plate 158, which passes the third brush 152 at the rotation axis 154 in the conveying direction (e.g., the material flow direction).

[0094] In this example, because the sole 204 has a cup-shaped structure, the direction of brush rotation can be chosen to prevent the bristles from engaging with the sidewalls of the sole 204 and causing interference with the surface to be brushed. For example, when the sole 204 is moved in the toe-to-heel direction, the brush can rotate clockwise as the toe of the sole 204 approaches to prevent the toe sidewall from bending into the foot-facing surface of the sole 204. In other words, when the third brush 152 rotates counterclockwise, the bristles of the third brush 152 can engage with the toe sidewall and push the sidewall towards the heel, thus obscuring a portion of the foot-facing surface of the sole 204. A similar obscuring of the foot-facing surface occurs when the third brush 152 rotates clockwise as the heel of the sole 204 approaches. To address this, some aspects envision changing the rotation direction of the third brush 152 based on the position of the sole 204 relative to the third brush 152.

[0095] The lower surface polishing module also includes a compression movement mechanism 1206 that effectively moves the pressure plate 158 in a plane parallel to the support plane 1202. The compression movement mechanism 1206 can be an actuator, such as a linear actuator, belt drive, chain drive, helical drive, pneumatic drive, hydraulic drive, etc. The compression movement mechanism 1206 can also move in the X, Y, and / or Z directions. For example, the compression movement mechanism 1206 effectively moves in the Z direction (i.e., perpendicular to the support plane 1202) to provide effective compression of the sole 204 against the support plane 1202 and the third brush 152. This compressive force provided by the compression movement mechanism 1206 can be measured at the sole 204 as 2 to 3 kg / cm². 3 In some instances, additional ranges of force or pressure were envisioned, such as 1 to 5 kg / cm². 3 .

[0096] Figure 13 The second configuration is described according to various aspects of this article. Figure 12 A front view of the lower surface polishing module. A second configuration is provided to show the rotation direction of the third brush 152, which is the same as... Figure 12 The rotation directions appear to be opposite. For example, when the heel end of the sole (and the associated portion of the pressure plate 158, which effectively holds the sole 204 close to the third brush 152 while also moving the sole 204 in the material direction) approaches the third brush 152, the third brush 152 can rotate in a counterclockwise direction. The third brush 152 can rotate more than 75% of the length of the pressure plate 158 in the first direction to provide a continuous polishing pattern on the main portion of the sole 204 before changing the direction of rotation. In an exemplary aspect, this unevenly distributed rotation along the length of the pressure plate can result in a more uniform polishing result on the majority of the area polished by the lower surface polishing module.

[0097] The pressure plate 158 is depicted as having a component contact surface 160 with a textured surface that forms a mating plane 1204 for conveying the sole 204. The texture can have any style and degree. In an exemplary aspect, the texture helps create a mechanical engagement between the pressure plate 158 and the footwear component, such that even in response to the rotational movement of the third brush 152 acting on the opposing surface of the sole 204, the linear movement in the material flow direction provided by the pressure plate 158 is translated into a similar movement by the sole 204. In other words, the texture of the component contact surface 160 provides more mechanical engagement to hold the sole 204 to the pressure plate 158 than the mechanical engagement created between the third brush 152 when polishing the sole 204.

[0098] The lower surface polishing module effectively polishes the lower surface of the footwear component. The process of polishing the lower surface of the footwear component using the lower surface polishing module can be expressed as a series of steps, including compressing the footwear component between a pressure plate 158 and a footwear component holder comprising a plurality of rollers 148, 150. Each of the plurality of rollers 148, 150 has a rotation axis parallel to the rotation axis 154 of a third brush 152. The rotation axis 154 is on a first side of a support plane 1202 formed by the plurality of rollers 148, 150. At least a portion of the bristles of the third brush 152 extends to a second side of the support plane 1202 for engagement with the footwear component. These steps include contacting at least a portion of the bristles of the third brush 152 with the footwear component at a first position (e.g., at the toe of the foot) and rotating the third brush 152 in a first direction at the first position. These steps additionally include conveying the article along the support plane 1202 by linear movement of the pressure plate 158. This conveying moves the footwear component from a first position to a second position in the first direction. At the second position, the third brush 152 rotates in the second direction while polishing the footwear component. During the polishing operation, the third brush 152 can engage with the footwear component such that the footwear component at the first position extends at least 5 mm into the diameter of the third brush 152.

[0099] Figures 14 to 17 Flowcharts are provided depicting various methods for polishing footwear components using the system provided herein. It is conceivable that additional steps may be included in these methods. It is also conceivable that various steps may be omitted from the methods provided herein. Furthermore, it is conceivable that the steps of these methods may be performed in a different order than depicted in the illustrated flowcharts, while still achieving polished footwear components.

[0100] Figure 14 A flowchart 1400 depicts a method for polishing components of a footwear article according to various aspects of this document. The method begins at block 1402, where the sidewalls of the footwear component are polished using a sidewall polishing module. The method continues to block 1404, where the footwear component is conveyed to an upper surface polishing module. This conveying can be achieved via a fork-like support and a compression mechanism (e.g., Figure 5 This is achieved using a conveying mechanism 502, which effectively retracts the footwear component from the footwear component holder of the sidewall polishing module and the upper surface polishing module and stores the footwear component in the footwear component holder. The method continues at frame 1406, where the upper surface of the footwear component is polished by the upper surface polishing module. At frame 1408, the method continues to convey the article to the lower surface polishing module. A conveying mechanism (such as...) can be used. Figure 5 The conveying mechanism 502 is used to perform the conveying. At box 1410, the method includes polishing the lower surface of the article at the lower surface polishing module.

[0101] Figure 15 A flowchart 1500 depicts a method for polishing the sidewall surface of a component of a footwear article according to various representations herein. At block 1502, the method includes compressing the footwear component (e.g., the article) between a support surface and a clamping surface (e.g., ...). Figure 7 The compression between the first clamp 704 and the first footwear component retainer 116. The method continues to frame 1504, where the rotating brush contacts the footwear component in a first position. For example, when the first brush 130 rotates at a first rate, the first brush 130 can be at any two reference marks (e.g., Figure 3 The sole 204 is contacted between (or at these two reference marks) A302, B304, C306, D308, E310, F312, G315, or H316, as depicted in box 1506. The method continues at box 1508, where a rotating brush contacts the article in a second position. The rotating brush can maintain contact with the footwear component from the first position to the second position to provide continuous polishing of surfaces (such as sidewall surfaces or other surfaces) to contact the footwear component in the second position. At box 1510, the rotating brush rotates at a second rate when in the second position. In examples, the second rate can be faster or slower than the first rate, and the difference in rotation rate can result in a variation in the speed at which the rotating brush travels along the surface of the footwear component to achieve a consistent polishing result.

[0102] Figure 16 A flowchart 1600 depicts a method for polishing the upper surface of a component of a footwear article according to various representations herein. The method begins at box 1602, which indicates compressing the footwear component against a support surface and a first clamping surface (e.g., Figure 9 The method continues to frame 1604, where a rotating brush (e.g., ...) is located between the first clamp 902 and the second footwear component retainer 138. Figure 9 The second brush 140) in the first position (e.g., Figure 9 The sole 204 (at the toe) contacts the footwear component. Frame 1606 provides rotation of the rotating brush in a first position in a first direction. Frame 1608 provides compression of the article between a supporting surface and a second clamping surface. For example, when... Figure 9 As the second brush 140 is conveyed along the ground-facing surface 208 to polish the surface, the second brush 140 approaches the portion of the ground-facing surface 208 that is obstructed by the first clamp. In this example, in order to polish the surface contacted by the first clamp, the second clamp (e.g., Figure 10The second clamp 904 holds the previously polished portion of the surface while the first clamp releases to expose the surface to be polished by the second brush 140. At frame 1610, the rotating brush contacts the footwear component in a second position different from the first position. At frame 1612, the brush rotates in a second direction in the second position. In this example, the alternative direction of rotation allows the polishing action of the rotating brush to aid in securing the footwear component (e.g., pushing the footwear component into the support surface) to the support surface, rather than the direction of rotation of the rotating brush inhibiting (e.g., lifting the footwear component from the support surface) securing the footwear component to the support surface.

[0103] Figure 17 A flowchart 1700 depicts a method for polishing the lower surface of a component of a footwear article according to various aspects of this document. The method includes block 1702, which depicts compressing the article against a compression member and multiple rollers (such as…). Figure 12 Between the pressure plate 158 and a plurality of rollers 148, 150. The method continues to frame 1704, where a rotating brush (such as a third brush 152) contacts the footwear component at a first position. Frame 1706 provides rotation of the rotating brush in a first direction at a first position on the surface of the footwear component. Frame 1708 provides rotation of the footwear component in the first direction (such as in…) Figure 9 The sole 204 (in the direction from toe to heel) is transmitted across the rotating brush. Frame 1710 provides rotation of the rotating brush in a second position, such as near the heel end (e.g., within 1 to 15 cm of the heel end), in a second direction.

[0104] at last, Figure 18 It describes the various aspects from this article. Figure 1 The system 100 has a bilinear configuration 1800. Although this description focuses on a single line for illustrative purposes, it is conceivable that multiple lines can operate in parallel. For example, the first line 1804 and the second line 1808 can operate in parallel in a common system. Each of the first line 1804 and the second line 1808 includes the lines described herein. Figure 1 All modules and concepts discussed in System 100. In an exemplary aspect, the right side of a pair of shoes is polished in the first of the two lines of the double-line configuration 1800, and the left side of the pair of shoes is polished in the second of the two lines. An operator may provide the shoe components at an inlet 1802 of the first line 1804, and an operator may provide the shoe components at an inlet 1806 of the second line 1808.
