  • This gradient of application can result in an insufficient amount of material application for quality control purposes.

  • a result of the greater coverage area of the second application pattern may, in an exemplary aspect depicted in FIG. 5 , be a reduction in application edge consistency that is therefore compensated for with an overlapping area with another application pattern or subsequent overlap with the same application pattern as will be discussed in FIG. 7 hereinafter.
  • a depth 504 is achieved in the area 412 .
  • a depth similar to depth 504 is also achieved in the area 410 , in an exemplary aspect. It is understood that the depth of the area 412 and 410 may be similar or different in aspects hereof. Similarly, it is contemplated that the depth 504 may be within a range of 10 to 60 micrometers to achieve acceptable quality metrics in footwear construction; however, it is contemplated as being greater or lesser in thickness in alternative aspects. Further, in an overlap area, such as area 414 , it is contemplated that the combination of materials from the first nozzle and from the second nozzle also results in a material thickness within the range of 10 to 60 micrometers. This exemplary range of adhesive thickness allows for traditionally used materials in the footwear manufacturing industry to achieve a sufficient bond for quality control purposes.

  • the material 602 deposited by the first nozzle 104 and the material 604 deposited by the second nozzle 106 of FIG. 4 overlap and form a converged portion 606 .
  • the height transition from material 602 to material 604 is not as pronounced as in the depiction of FIG. 5 as a result of material interactions, such as surface tension and material attraction as the materials interact at the converged portion 606 .
  • the converged portion 606 and the boundary portion of material 604 may have a smaller quantity in some portions than other portions, but the amount of material overlap to form the converged portion 606 is sufficient, in an exemplary aspect, to achieve quality standards.
  • FIG. 7 depicts a multipass material coverage 700 from a multiple-nozzle tool, in accordance with aspects hereof.
  • the material 724 is applied in two passes: a first pass 720 and a second pass 722 .
  • the multiple-nozzle tool applies material such that a first nozzle applies a first material 702 , 710 to a perimeter boundary forming boundary edges 704 and 712 , respectively.
  • the boundary edges provide a sufficient degree of consistency of material application at exterior perimeters.
  • the first nozzle 104 of FIG. 4 may be implemented to apply the material 702 and 710 .
  • a second material 706 in the first pass 720 and a second material 714 in the second pass 722 provide a greater coverage area of material than the first material 702 , 710 applications.
  • the second nozzle 106 from FIG. 4 may be effective for applying the second material 706 , 714 .
  • the first pass 720 and the second pass 722 cause an overlap 718 of second material 706 , 714 .
  • the overlap 718 of second material in an exemplary aspect, compensates for a more inconsistent boundary edge than provided by the first nozzle 104 , in an exemplary aspect.
  • the second material is applied to an internal area defined by an exterior perimeter of the boundary edges 704 , 712 , the lower consistency in application amount relative to the first material does not have as much of an impact on quality standards, in an exemplary aspect.
  • the second material may be applied to a central area of a sole as opposed to proximate where a biteline is defined, there is less opportunity for tearing or peeling to cause a separation of parts if the material is an adhesive at the central area as opposed to the biteline/intersection of disparate components.
  • overlaps compensate for variability in boundary edges that may occur with the application of the second material by a nozzle adapted to apply over a greater area with less consistency than a nozzle that applies a more precise, limited material, such as the first nozzle.
  • the overlapping portions of the second application patterns compensate for variability in the boundary edges of the second application pattern to ensure sufficient material is applied.
  • FIG. 8 depicts an application 800 of adhesive to a footwear component 802 (e.g., sole) by the multiple-nozzle tool 102 , in accordance with aspects hereof.
  • the tool 102 as previously described includes the first nozzle 104 having the first application pattern and the second nozzle 106 having the second application pattern, wherein the second application pattern provides a greater coverage area than the first application pattern.
  • the first application pattern provides a more controlled, precise, and consistently applied material at the boundary edges that ensures sufficient and appropriate material application at an application boundary/edge for quality control, in an exemplary aspect.
  • the footwear component 802 is depicted as a sole, but it can be any component in an article of footwear, such as a lasted upper.
  • the footwear component 802 is depicted as having a perimeter 804 at which an applied material is intended to be applied, but not to extend past.
  • the perimeter 804 may be a bonding edge, such as a biteline where a sole and an upper intersect. If the material extends beyond the perimeter 804 , the material may extend into a visible portion of the footwear that detracts from an intended visual appearance. Similarly, if the material fails to extend to the perimeter 804 , the sole and a bonded upper may be prone to separation at the intersection. As such, a consistent and precise application of material up to the perimeter 804 is attempted by use of the multiple-nozzle tool 102 and the first nozzle 104 .
  • the material application depicted in FIG. 8 is the first pass 720 from FIG. 7 prior to the application of the second pass 722 .
  • the first material 702 is applied such that the boundary edge 704 corresponds with the perimeter 804 .
  • the second material 706 covers a greater surface area of the footwear component 802 than the first material 702 .
  • an interior area is, in an exemplary aspect, an area that does not include a perimeter edge intended to have a high consistency application of material. With respect to footwear, an interior area may be the bottom surface of a lasted upper up to an area covered by a more precisely applied material.
  • the area within the perimeter 804 has material applied by the multiple-nozzle tool 102 .
  • the multiple-nozzle tool 102 may follow a robot tool path that controls the location of material application to ensure application up to the perimeter 804 and providing sufficient overlap between material portions and passes.
  • the tool path is depicted by an arrow 806 as the multiple-nozzle tool 102 extends from a medial side of the footwear component 802 towards a toe end before eventually heading in a heel-ward direction along the lateral side of the footwear component 802 , in this exemplary aspect.
  • This loop-like tool path allows for the second nozzle 106 to remain more proximate the interior and the first nozzle 104 to remain more proximate the perimeter 804 while applying material on the article of footwear component 802 , in this exemplary aspect.
  • the cross-section of FIG. 7 depicts an exemplary material application across an article of footwear component, such as the article of footwear component 802 of FIG. 8 .
  • FIG. 9 depicts an alternative multiple-nozzle tool 902 , in accordance with aspects hereof.
  • a first nozzle 904 is coupled by a coupling element 914 with a second nozzle 906 .
  • the first nozzle 904 has an output port 907 providing a first application pattern 910 of a material.
  • the second nozzle 906 has an output port 908 providing a second application pattern 912 of a material.
  • the first application pattern 910 is more controlled, precise, and consistent in material application at boundary edges than the second application pattern 912 .
  • the second application pattern 912 provides greater surface area coverage than the first application pattern 910 . Therefore, as discussed with respect to the multiple-nozzle tool 102 previously, the first nozzle is adapted to apply material, such as adhesive, proximate a perimeter and the second nozzle is adapted to apply material over a larger surface area with less edge boundary precision.
  • an angle between the first nozzle 904 and the second nozzle 906 as maintained by the coupling element 914 is configured such that the first application pattern 910 and the second application pattern 912 overlap at a component's (e.g., sole) surface at a known distance therefrom to ensure sufficient material application.
  • a component's e.g., sole
  • pressure, nozzle angle, volume, approach angle, and the like may all be varied dynamically during the application of the material by one or more instructions from a computing device. Therefore, a static configuration is not limiting.
  • FIG. 10 depicts a flow diagram representing a method 1000 of applying material with a multiple-nozzle tool, in accordance with aspects hereof.
  • material is applied to an article from a multiple-nozzle tool, such as the multiple-nozzle tool 102 of FIG. 1 or from the multiple-nozzle tool 902 of FIG. 9 .
  • the material may be any material, such as a colorant, adhesive, primer, or surface treatment.
  • the material may be liquid, gel, particulate, or the like.
  • some materials may be powder based, some may be liquid based, and some may be viscous solutions.
  • the application of the material may be controlled by a computing device in connection with one or more components, such as a movement mechanism (e.g., robot), a vision system, material pressurization/pump components, and the like.
  • the method continues contemporaneously applying the material from a second nozzle of the multiple-nozzle tool to the article.
  • the first nozzle applies the material at an application perimeter edge and the second nozzle applies the material more interior on the article from the application perimeter edge.
  • Contemporaneous application of the material contemplated both the first and second nozzles applying the material at a common time to prevent, in an exemplary aspect, a multiple-pass operation of discrete tools. Instead, a common tool movement can position both the first nozzle and the second nozzle appropriately for application of material. This may reduce cycle time for applying the material as the number of independent movements may be reduced, in an exemplary aspect.
  • an interior portion of an article is a location on the article that is distal from a perimeter at which consistency (e.g., consistent volume of material, precise application of material) is intended.
  • the first nozzle applies a smaller volume of material over a smaller area than the second nozzle.
  • the second nozzle applies a greater volume of material in a given time than the first nozzle that is contemporaneously applying material, in an exemplary aspect.
  • the method may also include moving the multiple-nozzle tool while applying the material such that the material applied from the second nozzle at a first time overlaps with the material applied by the second nozzle at a second time. This creates the overlap 718 of FIG. 7 . Additionally, this allows for the first nozzle to continue to apply material along a perimeter and the second nozzle to apply material at an interior portion while still providing the material across the whole intended article, in an exemplary aspect.
  • nozzles may be implemented. For example, a three, four, or five-nozzle system may be used.
  • Each of the nozzles may have different application patterns depending on the article and intended application. Therefore, it is contemplated that a consistent application pattern may be used within an interior of the article and a large surface area application pattern may be used proximate a perimeter, in an exemplary aspect.
  • FIGS. 11 and 12 depict a multiple-nozzle tool system 1100 , in accordance with aspects hereof.
  • the multiple-nozzle tool 102 is depicted as being moveable by the movement mechanism 112 , in this depiction.
  • Efficiencies of the system may be achieved through the independently moveable conveyance mechanisms 1102 , 1104 capable of retrieving, positioning, and delivering one or more parts relative to the multiple-nozzle tool 102 .
  • the retrieval and delivery portions of a manufacturing cycle may not utilize the multiple-nozzle tool 102 , causing that tool to remain idle during those portions.
  • 11 is positioned by the conveyance mechanism 1102 for the multiple-nozzle tool 102 to apply material (e.g., adhesive) thereto while a second part 1108 is depicted as being retrieved by the conveyance mechanism 1104 .
  • material e.g., adhesive
  • FIG. 12 the first part 1106 is delivered following the application of material by the multiple-nozzle tool 102 and the second part 1108 has been retrieved and is receiving material from the multiple-nozzle tool 102 .
  • This reciprocating action reduces cycle time and increases the return on investment for the multiple-nozzle tool 102 as it is applying material a greater portion of time rather than sitting idle as parts are retrieved and/or delivered.
  • a first step may include retrieving a first part with a first conveyance mechanism.
  • the first part is positioned by the first conveyance mechanism in a location suitable for a multiple-nozzle tool to apply material at defined locations with appropriate spray characteristics.
  • the multiple-nozzle tool applies a material, such as an adhesive, to the first part at specified locations with at least a first and a second nozzle working in cooperation to efficiently and precisely apply the material along a defined boundary and interior portion.
  • the first part is delivered from the multiple-nozzle tool by the first conveyance mechanism.
  • a second conveyance mechanism retrieves a second part prior to the second part being delivered by the first conveyance mechanism. For example, while the first part is having material applied thereon by the multiple-nozzle tool, the second conveyance mechanism may retrieve the second part. Following the application of material to the first part, the multiple-nozzle tool may then reposition to apply material to the second part. During the application of material to the second part, the first part may be delivered by the first conveyance mechanism, in an exemplary aspect.
  • FIGS. 11 and 12 While one or more multiple-nozzle tools are depicted in connection with FIGS. 11 and 12 , it is contemplated that the arrangement and configurations provided may be implemented with any tool or process. For example, it is contemplated that a sewing machine, a printer, a painter, a cutting machine, an assembly apparatus, and the like may be implemented in connection with the depicted conveyance mechanism arrangements to achieve manufacturing efficiencies, in exemplary aspects. For example, instead of a multiple-nozzle tool performing an operation as described in connection with FIGS.
  • a material coating tool e.g., a paint sprayer, an ink sprayer, a durable water repellant applicator, or the like
  • a material coating tool may apply one or more materials to portions of article of footwear in a manner similarly depicted in FIGS. 11 and 12 .
  • alternative tool paths may be implemented in connection with FIGS. 11 and 12 . For example, depending on an operation to be performed, a different tool path used by the tool performing the operation may be implemented to achieve the operation.
