  • Publication number: 20180343980
    Abstract: Systems and methods for monitoring the quality of a surface treatment applied to an article in a manufacturing process are provided. A surface treatment may be applied to at least a portion of an article. A thermal profile of the article may be obtained and used to determine temperature indications of different regions of the article to which the surface treatment has been applied. A standard model of the article may be obtained that includes model regions having model temperature ranges. The temperature indications of the article can be compared with the model temperature ranges to determine if any temperature indications are outside of a corresponding model temperature range. The article may be a shoe part. The surface treatments may include the application of heat, plasma, dye, paint, primer, and/or the application of other materials, substances, and/or processes.

  • Publication number: 20180345300
    Abstract: A nozzle dispenses a material, such as an adhesive, primer, paint, or other coating, through a dispensing port on to a substrate. The spray pattern provided by the nozzle defines, at least in part, an application pattern of the material on to the substrate. An air mask port integral with the nozzle or a separate nozzle expels a mask stream of pressurized gas. The mask stream projects toward the substrate to aid in limiting an application of the material beyond an application line on the substrate. The air-mask port and the dispensing port may be moved relative to the substrate and/or the application line such that the mask stream provides a barrier to the material being applied.

  • Publication number: 20180325219
    Abstract: An apparatus for buffing a shoe part includes a housing adapted to be articulated around at least a portion of the footwear part. A rotating spindle is positioned in the housing and has a buffing surface for engagement with the footwear part. A carriage is slideably connected to the housing and holds the spindle such that the buffing surface can be moved closer to and further away from the footwear part. An actuator is in the housing and in contact with the carriage. The actuator applies force to the carriage to increase the force of the buffing surface onto the footwear part. A biasing member is in the housing and in contact with the carriage. The biasing member exerts force onto the carriage in a direction opposite the force exerted by the actuator.

  • Publication number: 20180279722
    Abstract: Manufacturing of a shoe or a portion of a shoe is enhanced by executing various shoe-manufacturing processes in an automated manner. For example, shoe parts may be retrieved and temporarily assembled according to preset relative positions to form part stacks. The part stacks may be retrieved with the relative positioning of the shoe parts being maintained and placed at a stitching machine for more permanent attachment via stitching of the parts to form a shoe assembly. Movement during stitching of a conveyance mechanism that transfers the part stack from the stacking surface to the stitching machine and movement of a needle associated with the stitching machine may be controlled by a shared control mechanism such that the movements are synchronized with respect to one another. Vision systems may be leveraged to achieve movement and position information between and at machines and locations.

  • Publication number: 20180251608
    Abstract: Rubber pellets are coated with an anti-tack material. The anti-tack material may be comprised of a metallic stearate, such as magnesium stearate. The coated rubber pellets are loaded on to a rotational conveyance mechanism that rotates at a speed and radial amount to provide an interaction time between the rubber pellets and the anti-tack material. The coated rubber pellets may then be dried in a centrifuge dryer having a plurality of angled fins extending from a rotational shaft.

  • Patent number: 10065326
    Abstract: Acquisition or pick-up tools that themselves aid in improving the ease with which images of an acquired substrate may be captured, and methods of operating such pick-up tools, are provided. The pick-up tools may include a pick-up surface adapted to interface with a foreign substrate and a light source integrated with the pick-up tool such that light emitted from the light source passes through the pick-up surface to the foreign substrate when the foreign substrate is temporarily coupled with the pick-up surface to create a silhouette of the foreign substrate. A vision system may be adapted for capturing the silhouette of the foreign substrate when the foreign substrate is temporarily coupled with the pick-up surface. The substrate pick-up surface may be formed of one of a transparent, a semi-transparent, or a translucent material such that light may at least partially pass there through.

  • Publication number: 20180169913
    Abstract: Molded rubber objects may be molded and de-molded by defining both a desired final form for the molded rubber object and a tab extending from the final form of the molded rubber object using a cavity in a mold. Rubber pellets may be dispensed in predetermined amounts at desired location(s) within the cavity to provide the rubber needed to form the molded rubber object. Heat and pressure may be applied to the mold to cause the rubber pellets to fill the cavity defining both the desired final form of the molded rubber object and the tab. After the heat and pressure has been applied, a gripping device may grasp the tab and move the tab in a direction and with sufficient force to peel the rubber object from the mold cavity. If desired, the tab may be removed from the molded rubber object.

  • Publication number: 20180129185
    Abstract: Manufacturing of a shoe or a portion of a shoe is enhanced by executing various shoe-manufacturing processes in an automated fashion. For example, information describing a shoe part may be determined, such as an identification, an orientation, a color, a surface topography, an alignment, a size, etc. Based on the information describing the shoe part, automated shoe-manufacturing apparatuses may be instructed to apply various shoe-manufacturing processes to the shoe part, such as a pickup and placement of the shoe part with a pickup tool.
