Modes for Carrying Out the Invention

[0011] Hereinafter, embodiments will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated. <Embodiment 1> In Embodiment 1, an example of the scenario to which the present invention is applied will be described. First, in Embodiment 1, for example, in a store, a shoe manufacturing system for manufacturing made-to-order shoes according to the user's feet will be described. In the following description, among the shoe manufacturing system, in particular, based on the foot shape data measured by the measuring device, shoe mold data is generated, and further, processing data for processing the members constituting the upper of the shoe is generated, and the part for manufacturing the shoe mold (last) and the upper will be described.

[0012] FIG. 1 is a schematic diagram showing a configuration example of a shoe manufacturing system 10 according to Embodiment 1. Referring to FIG. 1, the shoe manufacturing system 10 includes a data generation device 100, a measuring device 200 for measuring the foot shape, a shoe mold manufacturing device 400 for manufacturing a shoe mold based on the shoe mold data, and a processing device 600 for processing the members constituting the upper based on the processing data. Depending on the store, or from a remote location such as the user's home, the foot shape may be measured using a mobile terminal 300 such as a smartphone instead of the measuring device 200. Further, the data generation device 100 can communicate with a data server 500 installed inside or outside the store.

[0013] The data generation device 100 generates shoe mold data based on the foot shape data obtained from the measuring device 200 or the mobile terminal 300, and further generates processing data for processing the members constituting the upper of the shoe based on the shoe mold data. FIG. 2 is a schematic diagram showing a hardware configuration example of the data generation device 100 according to Embodiment 1. Referring to FIG. 2, the data generation device 100 includes a processor 102, a main memory 104, an input unit 106, an output unit 108, a storage 110, an optical drive 112, and a communication controller 120. These components are connected via a processor bus 118.

[0014] The processor 102 is composed of a CPU, a GPU, etc., and can read programs (for example, the OS 1102 and the processing program 1104) stored in the storage 110, expand them in the main memory 104, and execute them. In the processor 102, the processing program 1104 that calculates the shoe-type data based on a predetermined algorithm from the footprint data received by the input unit 106 (including the additional information if there is any) is executed. Further, in the processor 102, the processing program 1104 that further calculates the processing data for processing the members constituting the upper of the shoe based on the calculated shoe-type data is executed. The processor 102 that executes the processing program 1104 corresponds to the calculation unit of the data generation device 100.

[0015] The main memory 104 is composed of a volatile storage device such as a DRAM or an SRAM. The storage 110 is composed of a non-volatile storage device such as an HDD or an SSD, for example.

[0016] In the storage 110, in addition to the OS 1102 for realizing basic functions, a processing program 1104 for providing the function as the data generation device 100 is stored. That is, when the processing program 1104 is executed by the processor 102 of the data generation device 100, it calculates shoe type data from the foot type data and further calculates the processing data. Further, in the storage 110, a shoe type database 1106 including a plurality of shoe type data, a sole database 1108 including sole data corresponding to the area on the sole side of the shoe, and a member database 1109 including information on members constituting the upper are stored. Note that the shoe type data stored in the shoe type database 1106 may be only upper data corresponding to the area on the upper side of the shoe. Only the data frequently used is stored in the storage 110 in the shoe type database 1106, the sole database 1108, and the member database 1109, and the other data may be stored in the data server 500. Further, only lists are stored in the shoe type database 1106, the sole database 1108, and the member database 1109, and the plurality of shoe type data, the plurality of sole data, and the information itself on the members constituting the upper may be stored in the data server 500.

[0017] The input unit 106 includes an input interface that is connected to the measuring device 200 or the mobile terminal 300 and receives foot type data from the measuring device 200 or the mobile terminal 300. Further, the input unit 106 is composed of a keyboard, a mouse, a microphone, a touch device, etc., and can further receive additional information selected by the user. The additional information is information other than the information on the foot size and the shape of the foot, and from the content of the information, it can be classified into information on the shape of the shoe, information on the use of the shoe, and information on the user's foot. The information on the shape of the shoe includes information on the user's preference, information on the shoes the user is wearing, existing shoe type data, information on the shape of the opening, information on the material of the upper, information on the shape of the sole, etc. The information on the use of the shoe includes running data, information on the competition to be used, etc. The information on the user's foot includes information on the pressure on the instep, foot pressure information, information on the deformation of the foot type, etc.

[0018] In addition, the additional information can be classified into factual information and selection information based on the content of the information. Here, factual information is objective information that can be represented by numerical data such as length, pressure, speed, etc. On the other hand, selection information is subjective information of the user, such as loose, tight, fast, slow, etc., which is information selected through hearings with the user.

[0019] For example, as information regarding the user's preferences, there is information on the user's preferences that the shape of the toe area is "loose", the shape of the midfoot area is "tight", and the shape of the heel area is "normal". This information on the user's preferences is selection information that can be collected through hearings with the user, and can be obtained by having the user input their preferences for each area of the shoe into the portable terminal 300. The processor 102 may calculate shoe form data by reflecting not only the foot form data regarding the foot size and shape of the foot, but also the above additional information.

[0020] The output unit 108 includes an output interface that outputs the shoe form data calculated by the processor 102 to the shoe form manufacturing apparatus 400 and outputs the processing data to the processing apparatus 600. Further, the output unit 108 is composed of a display, various indicators, a printer, etc., and outputs the processing result from the processor 102 and the like.

[0021] The communication controller 120 exchanges data with other control devices and the like using wired communication or wireless communication. The data generation device 100 may exchange foot form data and additional information with the measurement device 200 or the portable terminal 300 via the communication controller 120, exchange shoe form data with the shoe form manufacturing apparatus 400 via the communication controller 120, or exchange processing data with the processing apparatus 600 via the communication controller 120. Note that a USB controller connected to the processor bus 118 may be provided separately from the communication controller 120 to exchange data with other control devices and the like via a USB connection.

[0022] The data generation device 100 has an optical drive 112, and a program stored therein may be read from a recording medium 114 (for example, an optical recording medium such as a DVD (Digital Versatile Disc)) that non-transiently stores a computer-readable program and installed in the storage 110 or the like.

[0023] A processing program 1104 or the like executed by the data generation device 100 may be installed via a computer-readable recording medium 114, or may be installed in a form downloaded from a server device or the like on a network. Also, the functions provided by the data generation device 100 according to Embodiment 1 may be realized by using a part of the modules provided by the OS.

[0024] FIG. 2 shows a configuration example in which the processor 102 executes a program to provide functions necessary for the data generation device 100. However, some or all of these provided functions may be implemented using a dedicated hardware circuit (for example, an ASIC or an FPGA). Also, the configuration of the data generation device 100 shown in FIG. 2 is an example and is not limited to this configuration.

[0025] The measuring device 200 is a three-dimensional foot scanner using laser measurement. By placing the foot on the top plate and having the laser measurement devices built into the walls provided on both sides sandwiching the foot move from the toe to the heel of the foot for measurement, three-dimensional foot data of the user can be obtained. Note that the measuring device 200 is not particularly limited as long as it can measure three-dimensional foot data. Also, a mobile terminal 300 such as a smartphone may be used to photograph the user's foot, acquire image data of the foot, and generate foot data from the image data of the foot photographed by software installed in advance.

[0026] Figure 3 is a schematic diagram of foot shape data. Figure 3(a) is a perspective view of three-dimensional foot shape data I obtained by measurement with the measuring device 200 or the mobile terminal 300. The foot shape data I shown in Figure 3(a) has a large amount of data depending on the resolution. Therefore, instead of directly sending the three-dimensional foot shape data I to the data generation device 100, the measuring device 200 or the mobile terminal 300 sends the foot shape data F converted into data based on the homologous model shown in Figure 3(b) to the data generation device 100. Here, the foot shape data F based on the homologous model is foot shape data that represents the object shape with a polyhedron of the same topological geometric structure using 295 points of data anatomically associated with the foot shape. Note that the foot shape data is not limited to the foot shape data F based on the homologous model, and as long as it can represent the object shape of the foot shape data I shown in Figure 3(a), it may be foot shape data based on a model created by dividing the foot shape into a plurality of predetermined cross-sections and connecting a plurality of representative points identified within the cross-section.

[0027] Although it has been described that the three-dimensional foot shape data I is converted into the foot shape data F based on the homologous model by the measuring device 200 or the mobile terminal 300, the three-dimensional foot shape data I may be converted into the foot shape data F based on the homologous model by the data generation device 100. Further, the mobile terminal 300 may not generate foot shape data by simply photographing the user's foot and acquiring image data of the foot, but may generate foot shape data by the data generation device 100 based on the image data of the foot photographed by the mobile terminal 300.

[0028] The shoe form manufacturing device 400 is a 3D printer, a CNC (computerized numerical control) machine tool, etc. that manufactures a shoe form based on shoe form data. If the shoe form manufacturing device 400 is a 3D printer, a three-dimensional shoe form is manufactured from resin based on the shoe form data generated by the data generation device 100. The shoe form to be manufactured is not limited to resin and may be cardboard or the like. When manufacturing a shoe form from the cardboard, the shoe form manufacturing device 400 may be a device that cuts the cardboard or a device that outputs a shape pattern for cutting the cardboard. Further, when the shoe form is a shoe form whose shape can be changed, the shoe form manufacturing device 400 becomes a device that changes the shoe form based on the shoe form data generated by the data generation device 100.

[0029] The processing device 600 is a cutting device or the like that cuts the members constituting the upper based on the processing data. If the members constituting the upper are sheet-like members such as cloth, the processing data is cutting data for cutting out the members constituting the upper from the sheet-like members. The members constituting the upper are not limited to sheet-like members such as cloth, and any member can be used as long as it can constitute the upper. For example, when a part of the upper is formed of resin, the members constituting the upper may be produced by a 3D printer.

[0030] If the processing device 600 is a cutting device, the data generation device 100 generates cutting data as the processing data suitable for the cutting device, and if the processing device 600 is a 3D printer, the data generation device 100 generates 3D data as the processing data suitable for the 3D printer. Since the processing device 600 can process the members constituting the upper based on the processing data without using a shoe mold, it is not limited to the material and manufacturing method of the shoe mold produced by the shoe mold manufacturing device 400. Further, since the processing device 600 processes the members constituting the upper only with the processing data, it is not necessary to wait for the shoe mold to be produced by the shoe mold manufacturing device 400 and then process the members constituting the upper. Therefore, since these operations can be performed in parallel, the time required to manufacture shoes can be shortened.

[0031] An example of shortening the time required to manufacture shoes will be described. First, in shoe manufacturing, it is mainly necessary to go through the following manufacturing steps (a) to (g). (a) Creation of shoe mold data (3D data) for the shoe mold (b) Creation of processing data (cutting data) for the upper from the shoe mold data (c) When producing the shoe mold from, for example, cardboard, creation of cardboard cut data from the shoe mold data and cutting the cardboard with a laser cutting device based on the cut data (d) Cutting the members constituting the upper with a laser cutting device based on the processing data (e) Assembly of the cut cardboard to produce an assembled shoe mold (f) Sew the cut member (e.g., cloth) into the shape of the upper (g) Cover the assembled shoe form with the sewn upper and heat it with steam to shrink the upper In such a manufacturing step, since the processing data of the upper is created in step (b) without waiting for the step of manufacturing the shoe form in (e), steps (c) and (d) can be performed in parallel. Since there is no need to wait for the timing of cutting the cardboard in (c) and cutting the members constituting the upper in (d), the start of the processing after step (e) can be advanced.

[0032] FIG. 4 is a schematic diagram for explaining how the data generation device 100 according to Embodiment 1 calculates shoe form data and processing data. First, the data generation device 100 selects shoe form data U close to the foot form data from the library La of a plurality of shoe form data stored in the shoe form database 1106 (step S4a). Further, the data generation device 100 selects sole data determined in advance according to the shoes to be manufactured, or sole data selected by the user, from the library Lb of a plurality of sole data stored in the sole database 1108 (step S4b).

[0033] In the example shown in FIG. 4, an example of separately selecting and combining the shoe form data U and the sole data S is shown. However, the data generation device 100 may select only the shoe form data close to the foot form data from the library in which a plurality of shoe form data are stored, correct the upper data corresponding to the upper side region of the selected shoe form data to match the foot form data, and use the sole data corresponding to the sole side region as it is. Of course, the data generation device 100 may correct the upper data corresponding to the upper side region of the selected shoe form data to match the foot form data and correct the sole data corresponding to the sole side region to match the sole data selected by the user. Further, the data generation device 100 may calculate and generate shoe form data based on a predetermined algorithm from the foot form data instead of selecting and correcting data from the library stored in the database.

[0034] The data generation device 100 corrects the part of the selected shoe model data U that is different from the foot model data (for example, the surface part of the instep), and when there is input of additional information, generates the shoe model data U in which a specific part of the shoe model data U is corrected by reflecting the additional information (step S4c). Specifically, based on the user's preference information (additional information) that the shape of the toe area is "loose", the data generation device 100 increases the cross-sectional shape of the shoe model data of the toe area by, for example, 3%, and based on the user's preference information (additional information) that the shape of the heel area is "tight", decreases the cross-sectional shape of the shoe model data of the heel area by, for example, 2%.

[0035] Also, the data generation device 100 corrects the selected sole data S to match the selected shoe model data U (step S4d). The data generation device 100 combines the corrected shoe model data U and the corrected sole data S to generate the shoe model data K. The shoe model data K is the final shoe model data generated by calculation from the foot model data.

[0036] Furthermore, based on the generated shoe form data K, the data generation device 100 calculates machining data for machining the members constituting the upper of the shoe (step S4e). The data generation device 100 may calculate the machining data based only on the upper data corresponding to the upper side region of the shoe form data instead of the shoe form data. When the member constituting the upper is a sheet-like member, the machining data becomes cutting data for cutting out the shapes A1 and A2 of the upper from the sheet-like member as shown in FIG. 4. The shape A1 of the upper corresponds to the side surface portion of the upper, and the shape A2 of the upper corresponds to the bottom surface portion of the upper. Also, the shape A2 of the upper corresponds to the shape on the sole side of the shoe form data. Since the member constituting the upper is easy to be molded along the shape of the shoe form, a sheet-like member containing a thread having heat shrinkability may be adopted. The data generation device 100 may calculate the assumed heat shrinkage rate of the thread contained in the sheet-like member and correct the cutting data based on the calculation result. For example, the data generation device 100 may correct the cutting data so that the direction in which the heat shrinkage rate of the thread is large becomes larger than the other directions. Hereinafter, an example of a sheet-like member containing a thread having heat shrinkability will be described. Of course, the member constituting the upper is not limited to the sheet-like member described below, and may be other materials or members having other shapes.

[0037] FIG. 5 is a schematic view of a sheet-like member containing a thread having heat shrinkability. The sheet-like member shown in FIG. 5 includes a sheet-like first layer 31, a sheet-like second layer 32 laminated outside the first layer 31, and a sheet-like third layer 33 laminated inside the first layer 31. The first layer 31 includes a thread 311 having heat shrinkability. The first layer 31 is made of a knitted fabric (knitted fabric) or a woven fabric (woven fabric) having internal voids 312. The knitting method in the knitted fabric is not particularly limited, and can be, for example, raschel knitting or tricot knitting. The weaving method in the woven fabric is also not particularly limited, and can be, for example, plain weaving or twill weaving. Note that the sheet-like member is not limited to the case where it is composed of three layers of the first layer 31, the second layer 32, and the third layer 33.

[0038] The second layer 32 is made of a non-woven fabric. The non-woven fabric can be made of, for example, polyester fibers. Since the fibers of the non-woven fabric of the second layer 32 are intertwined, it does not have an internal void corresponding to the internal void 312 of the first layer 31.

[0039] In the upper part, the first layer 31 is disposed closer to the inside (the side closer to the wearer's foot when worn) than the second layer 32, and further, the third layer 33 is disposed closer to the inside than the first layer 31. That is, the first layer 31 is the middle layer, the second layer 32 is the outer layer, and the third layer 33 is the inner layer. The first layer 31, the second layer 32, and the third layer 33 are subjected to needle punching and the three layers are integrated. Although it has been described that the three layers of the first layer 31, the second layer 32, and the third layer 33 are integrated by needle punching, needle punching may not be performed.

[0040] Here, the "internal void" refers to the space existing between fibers such as yarns constituting a knitted or woven fabric, or between aggregates of fibers. Also, generally in a knitted or woven fabric, when the fibers are arranged so as to extend in the plane direction, it refers to the space penetrating in the normal direction of the plane, or the space divided in the plane direction. Further, when the distance is maintained between adjacent ones of the intersections of the fibers, it is the space surrounded by the intersections of a plurality of fibers. When using a fused yarn as described later, the intersections of the fibers after being fused by thermoforming the upper part are in a fixed state, and the intersecting fibers (yarns) are fixed to each other. The "internal void" corresponds to, for example, the mesh openings (refer to the internal void 312 formed by the yarn 311 (weft) and the yarn 313 (warp) in the woven fabric of the first layer 31 shown as the second overlapping sheet in FIG. 5) or the open portion of the fabric. In the first embodiment, the distance between adjacent intersections of the fibers is set to 1 to 5 mm. Alternatively, the space ratio in the plane direction occupied by the knitted or woven fabric is set to 15 to 30%. These two conditions can be set to satisfy either one of them.

[0041] Since the first layer 31 has the internal void 312, the deformation (shrinkage) of the heat-shrinkable yarn 311 and the movement of the intersecting yarns 313 (see Fig. 6(b)) accompanying this are allowed by the space of the internal void 312. Therefore, the space of the internal void 312 does not inhibit the deformation of the first layer 31 by the heat-shrinkable yarn 311. Accordingly, since the first layer 31 can be deformed as designed, it is easy to set the conditions (heating temperature, heating time, etc.) for heat shrinkage.

[0042] Fig. 6 is a schematic diagram for explaining the first layer 31 including the heat-shrinkable yarn 311. Fig. 6(a) is a perspective view schematically showing the configuration of a yarn made of a core-sheath material. Fig. 6(b) shows the initial state of the fabric, Fig. 6(c) schematically shows the state where the weft yarn has shrunk, and Fig. 6(d) schematically shows the state where the warp yarn and the weft yarn are welded.

[0043] The heat-shrinkable yarn 311 contained in the first layer 31 can be made of a core-sheath material in which a core 3111 (inner peripheral portion) and a sheath 3112 (outer peripheral portion) are integrally formed, as schematically shown in Fig. 6(a). This yarn 311 is a fusible yarn that fuses by heat, and the core 3111 and the sheath 3112 have different melting points. In this yarn 311, the melting point of the sheath 3112 is lower than that of the core 3111. For this reason, by heating the upper before molding when molding the upper, the entire yarn 311 is shrunk and only the portion of the sheath 3112 is melted. Therefore, the shape-retaining action by the sheath 3112 and the elastic action by the core 3111 can be made compatible. As this heat-shrinkable yarn 311, for example, a yarn containing a polyester resin, more specifically, a sheath-core material made of a polyester-based thermoplastic elastomer, and a sheath-core material in which the core 3111 is made of a polyester-based thermoplastic elastomer and the sheath 3112 is made of a polyamide-based thermoplastic elastomer can be used.

[0044] Further, the first layer 31 can be composed of a woven fabric in which one of the warp or weft is a yarn 311 having heat shrinkability, or a knitted fabric in which 10% or more is a yarn 311 having heat shrinkability. In the case of a woven fabric, the yarn 311 having heat shrinkability (warp or weft) is arranged along the width direction in the upper part. Note that it is (technically) common for the yarn 311 having heat shrinkability to be used as the weft. For this reason, FIG. 6(b) shows the configuration of the woven fabric in the first layer 31 when the yarn 311 having heat shrinkability is used as the weft. According to this configuration, by heating the first layer 31, as shown in FIG. 6(c), the yarn 311 (weft) shrinks in the length direction (due to the shrinkage in the direction indicated by the arrow, the interval between adjacent yarns 313 (warp), yarns 313 (warp) changes to be smaller). Then, the sheath 3112 of the yarn 311 made of the core-sheath material melts and adheres to the yarn 313 (warp) (the adhesion point 314 indicated by a black circle in FIG. 6(d)). In this way, the first layer 31 is deformed. By utilizing this deformation, it is possible to appropriately mold the upper into a desired shape, specifically, along the shape of a shoe.

[0045] As described above, the data generation device 100 according to the first embodiment generates shoe form data for manufacturing shoes from the measured foot form data. The data generation device 100 includes an input unit 106 that receives the foot form data, a processor 102 (calculation unit) that calculates shoe form data from the foot form data received by the input unit 106, and an output unit 108 that outputs the shoe form data calculated by the processor 102. The processor 102 further calculates processing data for processing the members constituting the upper of the shoe based on the calculated shoe form data. The output unit 108 further outputs the processing data calculated by the processor 102. The shoe manufacturing system 10 includes a measuring device 200 that measures the foot form and outputs the foot form data to the data generation device 100, the above-described data generation device 100, a shoe form manufacturing device 400 that manufactures a shoe form based on the shoe form data generated by the data generation device 100, and a processing device 600 that processes the members constituting the upper based on the processing data generated by the data generation device 100.

[0046] Accordingly, the data generation device 100 according to Embodiment 1 calculates processing data adapted to the processing device 600 that processes the members constituting the upper of the shoe. Therefore, it is not limited to the material and manufacturing method of the shoe mold, and the time required to manufacture the shoe can be shortened. Further, in the shoe manufacturing system 10, a shoe mold is manufactured from the shoe mold data generated by the data generation device 100, and the members constituting the upper are processed based on the processing data. Therefore, the members constituting the upper can be processed without waiting for the manufacture of the shoe mold, and the time required to manufacture the shoe can be shortened.

[0047] The shoe mold data preferably includes at least one of upper data (first data) corresponding to the area on the upper side of the shoe and sole data (second data) corresponding to the area on the sole side of the shoe. For example, when manufacturing shoes with the same-shaped soles, the sole data can be shared. Further, the processor 102 preferably calculates the processing data based on the upper data. Thereby, the object of calculating the processing data can be limited to the upper data.

[0048] The member constituting the upper is a sheet-like member, and the processing data is preferably cutting data for cutting at least one sheet-like member. In particular, the member constituting the upper is a sheet-like member containing a heat-shrinkable thread, and the processor 102 preferably calculates the assumed heat shrinkage rate of the thread contained in the sheet-like member and corrects the cutting data based on the calculation result. Thereby, the data generation device 100 can generate cutting data for cutting an appropriate shape of the upper from the sheet-like member to conform to the shape of the shoe mold. <Embodiment 2> In the data generation device 100 according to Embodiment 1, an example of calculating machining data for machining members constituting the upper of a shoe based on shoe form data was described. In the data generation device 100 according to Embodiment 2, not only machining data but also heating conditions for machining a sheet-like member are calculated. Note that the shoe manufacturing system and data generation device according to Embodiment 2 have the same configuration as the shoe manufacturing system 10 and data generation device 100 according to Embodiment 1, and the same reference numerals are given and detailed description will not be repeated.

[0049] Hereinafter, when the sheet-like member includes a heat-shrinkable thread, an example will be described in which the data generation device 100 calculates cutting data (machining data) for cutting the sheet-like member and also calculates heating conditions for heating the cut sheet-like member and shaping it to fit the shoe form. FIG. 7 is a flowchart for explaining a method by which the data generation device according to Embodiment 2 generates shoe form data from foot form data. First, the data generation device 100 receives foot form data measured by the measuring device 200 or the mobile terminal 300 (step S101).

[0050] The data generation device 100 receives information on members constituting the upper (step S102). Specifically, when the members constituting the upper are sheet-like members including a heat-shrinkable thread as shown in FIG. 5, the data generation device 100 receives information such as the shape of the sheet, the material, and the heat shrinkage rate of the thread used. Specifically, based on the information on the members constituting the upper selected by the user at the input unit 106, information corresponding to the members is read from a database stored in advance in the storage 110 or the data server 500. FIG. 8 is a diagram for explaining an example of a database in which information on members constituting the upper is stored.

[0051] In FIG. 8, information such as member A, member B, and member C, which constitute the upper, is stored in the database. As shown in FIG. 5, member A is a member that forms the upper with three layers integrated into a single sheet. Therefore, in the information of member A in the database, "sheet (3 layers)" is stored as shape information, "layer containing heat-shrinkable yarn" is stored as material information, and "heat shrinkage rate" information is stored as other information. Member B is a member that forms the upper with three sheets. Therefore, in the information of member B in the database, information on sheet B1, information on sheet B2, and information on sheet B3 are stored. In the information of sheet B1, "sheet (B1)" is stored as shape information, and "cloth" is stored as material information. In the information of sheet B2, "sheet (B2)" is stored as shape information, and "resin" is stored as material information. In the information of sheet B3, "sheet (B3)" is stored as shape information, "containing heat-shrinkable yarn" is stored as material information, and "heat shrinkage rate" information is stored as other information. Member C is a member that forms the upper by processing with a 3D printer. Therefore, in the information of member C in the database, "processed with a 3D printer" is stored as shape information, "thermoplastic resin" is stored as material information, and "3D printer setting conditions" information is stored as other information.

[0052] Returning to FIG. 7, the data generation device 100 calculates shoe form data from the foot form data (step S103). Based on the shoe form data calculated in step S103, the data generation device 100 calculates processing data for processing the members that constitute the upper of the shoe (step S104). The processing data calculated by the data generation device 100 differs depending on the information of the members that constitute the upper received in step S102. Specifically, when the member that constitutes the upper is member A, the data generation device 100 calculates cutting data for cutting the shape of the upper from a single sheet. Since member A has a layer containing heat-shrinkable yarn, the data generation device 100 calculates the assumed heat shrinkage rate of the yarn contained in the sheet-like member and corrects the cutting data based on the calculation result.

[0053] Also, when the member constituting the upper is member B, the data generation device 100 calculates cutting data for cutting the shape of the upper for each of the three sheets. Since sheet B3 contains a thread having heat shrinkability, the data generation device 100 calculates the assumed heat shrinkage rate of the thread contained in the sheet-like member, and corrects the cutting data of sheet B3 based on the calculation result. Further, when the member constituting the upper is member C, the data generation device 100 calculates processing data for processing the shape of the upper with a 3D printer.

[0054] Returning to FIG. 7, the data generation device 100 determines whether the member constituting the upper is a sheet-like member containing a thread having heat shrinkability (step S105). When the member constituting the upper is a sheet-like member containing a thread having heat shrinkability (YES in step S105), the data generation device 100 calculates information regarding heating conditions based on the information of the member constituting the upper received in step S102 and the processing data calculated in step S104. Specifically, information such as the material and heat shrinkage rate of the thread having heat shrinkability can be obtained from the information of the member constituting the upper, and information such as the size of the upper can be obtained from the processing data. The data generation device 100 calculates heating conditions such as the heating temperature and heating time when the member constituting the upper is steam-heated and molded to fit the shoe form based on this information. For example, if the size of the upper is large, the data generation device 100 increases the heating time, and if the thread has a high heat fusion temperature, the data generation device 100 increases the heating temperature.

[0055] In addition, when the data generation device 100 calculates processing data for processing the shape of the upper with a 3D printer, it may calculate the setting conditions of the 3D printer from the information of the member constituting the upper. Specifically, the data generation device 100 calculates optimal setting conditions considering information such as the size of the upper obtained from the processing data based on the setting conditions of the 3D printer obtained from the information of the member constituting the upper.

[0056] After step S106, or when the member constituting the upper is not a sheet-like member including a thread having heat shrinkability (NO in step S105), the data generation device 100 outputs the calculated results (boot mold data, processing data, heating conditions, etc.) from the output unit 108. (Step S107) The boot mold data output from the data generation device 100 is received by the boot mold manufacturing device 400. The boot mold manufacturing device 400 manufactures a boot mold based on the received boot mold data. The processing data output from the data generation device 100 is received by the processing device 600. The processing device 600 processes the member constituting the upper based on the received processing data. When the processing data is cutting data, the processing device 600 cuts out the shape of the upper from the sheet-like member based on the cutting data. The heating conditions output from the data generation device 100 are received by a heating device (not shown). The heating device heats the member constituting the upper based on the received heating conditions and can form the shape of the upper along the shape of the boot mold.

[0057] As described above, in the data generation device 100 according to the second embodiment, the processor 102 calculates information regarding the heating conditions when processing the sheet-like member cut with the cutting data, and the output unit 108 further outputs the information regarding the heating conditions calculated by the processor 102. Thereby, it becomes possible to form an appropriate shape of the upper along the shape of the boot mold.

[0058] Further, it is preferable that the input unit 106 further receives information on the member constituting the upper, and the processor 102 corrects the processing data based on the received information on the member constituting the upper. For example, when the member constituting the upper is member B, the processor 102 calculates the assumed heat shrinkage rate of the thread of the sheet B3 including the thread having heat shrinkability, and corrects the cutting data (processing data) based on the calculation result, but does not correct the cutting data (processing data) for the other sheets B1 and B2. Thereby, the data generation device 100 can generate processing data for processing an appropriate shape of the upper for conforming to the shape of the boot mold.

[0059] Furthermore, when the members constituting the upper are composed of a plurality of sheet-like members, the processor 102 preferably calculates cutting data for each of the sheet-like members. For example, when the member constituting the upper is member B, the data generation device 100 calculates cutting data for each of sheets B1 to B3. Thereby, the data generation device 100 can generate optimal cutting data for each of sheets B1 to B3. <Other Modifications> In FIG. 1, the shoe manufacturing system 10 of one store including the data generation device 100, the measuring device 200, the shoe mold manufacturing device 400, and the processing device 600 has been described. However, depending on the store, a store that does not have the measuring device 200 and measures the foot shape using a mobile terminal 300 such as a smartphone may be included in the shoe manufacturing system 10. Also, a store that does not have the shoe mold manufacturing device 400 and the processing device 600, and manufactures shoes by manufacturing a shoe mold with the shoe mold manufacturing device 400 of another store or manufacturing an upper with the processing device 600 may be included in the shoe manufacturing system 10. FIG. 9 is a schematic diagram showing a state where shoe manufacturing systems of various stores are connected to the data server 500.

[0060] As shown in FIG. 9, the shoe manufacturing system 10 is arranged in each of a plurality of stores A to C. For example, stores A and C are small stores in the city, and in stores A and C, a store clerk takes a picture of the user's foot with the mobile terminal 300 and measures the foot shape data with the mobile terminal 300, or the user himself measures the foot shape data with the mobile terminal 300 at home or the like and the store accepts it. On the other hand, store B is a large store in a shopping mall or the like, and in store B, a store clerk measures the user's foot with the measuring device 200 to obtain foot shape data. The foot shape data obtained at each of stores A to C is processed by the data generation device 100 at each store, but may be stored in the data server 500 arranged at a manufacturer or the like together with the user's personal information via the network 5.

[0061] In the manufacturer, the shoe last data and sole data of existing shoes are created and stored in the shoe last database and the sole database in the data server 500. By storing the shoe last data and sole data of existing shoes in the shoe last database and the sole database in the data server 500, it is possible to select shoe last data close to the foot type data from the library of the shoe last database or select the sole data selected by the user from the library of the sole database from the data generation device 100 provided in the store. In addition, the data generation device 100 can search for the shoe last data and sole data of the shoes used by the user from the shoe last database and the sole database in the data server 500. The information stored in the data server 500 is not limited to the shoe last data and sole data of existing shoes, and may also store the user's running data, the shoe last data created by the user last time, information on the competition to be used, information on the material of the upper, and the like.

[0062] Note that the data server 500 is not limited to being arranged in a manufacturer different from the store, and may be arranged in other places or within a specific store. For example, the data server 500 may be arranged in any one of stores A to C. In addition, a plurality of shoe manufacturing systems 10 may be arranged in one store, and furthermore, a local data server communicable with the plurality of shoe manufacturing systems 10 may be arranged in the one store. Also, the data server 500 may be realized in the form of a cloud service.

[0063] The embodiments disclosed this time should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is shown not by the above description but by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
