[0003] [Patent Document 1] Patent No. 6685303 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, shoe molds for making custom-made shoes have had to be made using a cutting machine or a three-dimensional printer (hereinafter referred to as a "3D printer"). However, in recent years, shoe molds made by various manufacturing methods have been developed. In this disclosure, a model name is given to each shoe mold made by a different manufacturing method, and for example, a shoe mold made by a cutting machine is called a cutting machine model, and a shoe mold made by a 3D printer is called a 3D printer model. These models of shoe molds made by different manufacturing methods are collectively called a shoe mold model.

[0011] Hereinafter, each embodiment will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[0012] [Embodiment 1] In the first embodiment, an example of a situation in which the present invention is applied will be described. In the first embodiment, a shoe last making device will be described that measures a user's foot shape in a store, selects at least one shoe last model from a plurality of shoe last models made by different manufacturing methods based on the measured user's foot shape, and outputs shoe last making data corresponding to the selected shoe last model.

[0013] Fig. 1 is a diagram for explaining an overview of a shoe last production assisting device 100 according to embodiment 1. Referring to Fig. 1, the shoe last production assisting device 100 is installed in a store. The shoe last production assisting device 100 can communicate with a measuring device 200, a mobile terminal 300 such as a smartphone, and / or a data server 500.

[0014] The measuring device 200 is used to measure the foot shape of a user. The measuring device 200 may be installed in the same store as the shoe last making assisting device 100, or may be installed in a store different from the shoe last making assisting device 100. The mobile terminal 300 is used to measure the foot shape of a user at the user's home or in a store that does not have the measuring device 200. The data server 500 is installed in a manufacturer and stores personal information of the user, the user's shoe purchase history, shoe last data of existing shoes, shoe last data created by the user last time, etc.

[0015] The shoe last production support device 100 receives the user's foot last data from the measurement device 200 or the mobile terminal 300, and selects at least one type of shoe last model from among a plurality of types of shoe last models made by different methods based on the received user's foot last data. In the first embodiment, a 3D printer model, a cutting machine model, a flat part model, a variable model, a three-dimensional part model, and a hybrid model are adopted as the shoe last model. Details of each shoe last model will be described later with reference to Figs. 4 and 5.

[0016] Furthermore, the shoe last making assisting device 100 calculates making data (described later with reference to FIG. 7) necessary for making a shoe last corresponding to the selected shoe last model, and displays the calculated making data on the display 150.

[0017] The shoe last production assisting device 100 may receive shoe last data used to produce the user's shoes, and select at least one shoe last model from among a plurality of shoe last models with different manufacturing methods based on the received shoe last data. In this case, the shoe last production assisting device 100 acquires shoe last data of shoes previously purchased by the user or shoe last data created by the user from the data server 500 as shoe last data to be used to produce the user's shoes.

[0018] Furthermore, the shoe last production assisting device 100 may output the production data by a printer, or may transmit the production data to a shoe last production device 400 that can communicate with the shoe last production assisting device 100.

[0019] Fig. 2 is a schematic diagram showing an example of a hardware configuration of the shoe last production assisting device 100 according to the embodiment 1. With reference to Fig. 2, the shoe last production assisting 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.

[0020] The processor 102 is composed of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), etc., and can read out programs (for example, an OS (Operating System) 1102 and a processing program 1104) stored in the storage 110, deploy them in the main memory 104, and execute them. The processor 102 executes the processing program 1104, which selects a shoe last model based on a predetermined algorithm from the foot last data or shoe last data received by the input unit 106, and calculates production data for a shoe last corresponding to the selected shoe last model. The processor 102 that executes the processing program 1104 corresponds to the calculation unit of the shoe last production assisting device 100.

[0021] The main memory 104 is configured with a volatile storage device such as a dynamic random access memory (DRAM) or a static random access memory (SRAM). The storage 110 is configured with a non-volatile storage device such as a hard disk drive (HDD) or a solid state drive (SSD).

[0022] The storage 110 stores an OS 1102 for realizing basic functions, as well as a processing program 1104 for providing the functions of the shoe last production assisting device 100. That is, the processing program 1104 is executed by the processor 102 of the shoe last production assisting device 100 to select a shoe last model and calculate production data of a shoe last corresponding to the selected shoe last model. Furthermore, the storage 110 stores a foot last database 1106, a shoe last database 1107, and a recommended shoe last model database 1108.

[0023] The foot shape database 1106 stores reference foot shape data by size. Average foot shape data is used as the reference foot shape data. Note that the foot shape database 1106 may store reference foot shape data not only by size but also by gender, age, and / or purpose.

[0024] The shoe last database 1107 stores reference shoe last data by size. Average shoe last data is used as the reference shoe last data. Note that the shoe last database 1107 may store reference shoe last data not only by size but also by gender, age, and / or purpose.

[0025] Recommended shoe last models are stored by condition in the recommended shoe last model database 1108. The recommended shoe last model database 1108 is referenced when the processor 102 selects a shoe last model. The recommended shoe last models will be described later with reference to FIG.

[0026] Note that the foot pattern database 1106 and the shoe pattern database 1107 may store only frequently used data in the storage 110, and the other data may be stored in the data server 500. Also, the foot pattern database 1106 and the shoe pattern database 1107 may store only lists, and a plurality of pieces of foot pattern data and a plurality of pieces of shoe pattern data themselves may be stored in the data server 500.

[0027] The input unit 106 receives information related to the user's shoes. The input unit 106 includes an input interface that is connected to the measuring device 200, the mobile terminal 300, or the data server 500 and receives information from the measuring device 200, the mobile terminal 300, or the data server 500. The input unit 106 also includes a keyboard, a mouse, a microphone, a touch device, and the like for receiving information. The input unit 106 that receives information related to the user's shoes corresponds to the reception unit of the shoe last making assisting apparatus 100.

[0028] The output unit 108 outputs the production data calculated by the processor 102. The output unit 108 is composed of a display, various indicators, a printer, etc., and outputs processing results and the like from the processor 102. The output unit 108 may also include an output interface that outputs the production data calculated by the processor 102 to the shoe last making device.

[0029] The communication controller 120 exchanges data with other control devices, etc., using wired or wireless communication. The shoe last production assisting device 100 receives foot last data from the measurement device 200 or the mobile terminal 300 via the communication controller 120. The shoe last production assisting device 100 may also receive shoe last data from the data server 500 via the communication controller 120. The shoe last production assisting device 100 may also transmit production data to the shoe last production device 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, and data may be exchanged with other control devices, etc., via the USB connection.

[0030] The optical drive 112 reads a program stored in a recording medium 114 (e.g., an optical recording medium such as a DVD (Digital Versatile Disc)) that non-transiently stores a computer-readable program, and installs the read program in the storage 110, etc.

[0031] The processing program 1104 executed by the shoe last making assisting device 100 may be installed via the computer-readable recording medium 114, or may be installed by downloading from a server device on a network. The functions provided by the shoe last making assisting device 100 according to the first embodiment may be realized by using some of the modules provided by the OS.

[0032] 2 shows an example of a configuration in which the processor 102 executes a program to provide functions required for the shoe last production assisting device 100, but some or all of these provided functions may be implemented using a dedicated hardware circuit (for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array)). The configuration of the shoe last production assisting device 100 shown in FIG. 2 is merely an example, and is not limited to this configuration.

[0033] 3 is a diagram showing an example of a functional configuration of the shoe last production assisting apparatus 100 according to embodiment 1. The shoe last production assisting apparatus 100 includes a receiving unit 131, a calculating unit 132, and an output unit .

[0034] The reception unit 131 is realized by the above-mentioned input unit 106. The reception unit 131 receives information about the user's shoes. The information about the user's shoes includes factual information and information about the shoes selected by the user (hereinafter referred to as "selection information").

[0035] The actual information is foot shape data of the user or shoe shape data used to make shoes for the user. The foot shape data of the user is transmitted from the measurement device 200 or the mobile terminal 300. The shoe shape data used to make shoes for the user is transmitted from the data server 500.

[0036] The selection information is, for example, a request regarding the shape of the shoes, the intended use of the shoes, a request regarding the upper material, a request regarding delivery date, and / or a request regarding cost. A request regarding the shape of the shoes is, for example, a request regarding the degree of tightness (tight, loose, etc.) and a request regarding the height of the opening. A request regarding the intended use of the shoes is, for example, everyday use, walking, running, a specific sport, etc. A request regarding the upper material is, for example, a request to use a heat-shrinkable material for the upper. A request regarding delivery date is, for example, how many days the shoes should be delivered. A request regarding cost is, for example, at what cost the shoes should be made.

[0037] The selection information is input by the user using a keyboard, a mouse, a microphone, a touch device, or the like. Note that the selection information shown in FIG. 3 is merely an example, and the selection information is not limited to these. The selection information may also include information on shoes currently worn by the user, information on shoes worn by the user in the past, and the like. In addition, it is preferable that the information on the user's shoes received by the receiving unit 131 includes both fact information and selection information, but it is sufficient that at least fact information is included, and selection information does not have to be included.

[0038] The calculation unit 132 is realized by the above-mentioned processor 102. When the factual information accepted by the acceptance unit 131 is the user's foot shape data, the calculation unit 132 refers to the foot shape database 1106 and extracts foot shape data close to the accepted user's foot shape data as reference foot shape data. The calculation unit 132 compares the user's foot shape data with the extracted reference foot shape data and calculates the difference between the user's foot shape and the reference foot shape. The calculation unit 132 refers to the recommended shoe last model database 1108 and selects a shoe last model corresponding to the difference. The calculation unit 132 calculates production data required to produce a shoe last corresponding to the selected shoe last model based on the user's foot last data.

[0039] When the factual information received by the receiving unit 131 is shoe last data used to make the user's shoes, the calculation unit 132 refers to the shoe last database 1107 and extracts shoe last data close to the accepted shoe last data used to make the user's shoes as reference shoe last data. The calculation unit 132 compares the shoe last data used to make the user's shoes with the extracted reference shoe last data and calculates the difference between the shoe last used to make the user's shoes and the reference shoe last. The calculation unit 132 refers to the recommended shoe last model database 1108 and selects a shoe last model corresponding to the difference. The calculation unit 132 calculates production data required to make a shoe last corresponding to the selected shoe last model based on the shoe last data used to make the user's shoes.

[0040] When the receiving unit 131 receives a request (selection information) regarding the shape of the shoes other than the factual information, the calculation unit 132 may correct the calculated difference amount based on the request and select a shoe last model according to the corrected difference amount. In detail, the calculation unit 132 refers to the recommended shoe last model database 1108 and selects a shoe last model corresponding to the corrected difference amount.

[0041] In such a case, the calculation unit 132 outputs production data based on the user's foot shape data or shoe last data used to produce the user's shoes, and the user's request regarding the shape of the shoes.

[0042] In addition, when the receiving unit 131 receives, in addition to the factual information, information (selected information) about shoes the user is currently wearing or shoes (selected information) that the user has worn in the past, the calculation unit 132 may identify the tendency of the user's feet (spreading to the sides, bunions, etc.) based on the information, correct the calculated difference amount based on the identified tendency, and select a shoe model according to the corrected difference amount.

[0043] In such a case, the calculation unit 132 outputs production data based on the user's foot shape data or shoe shape data used to produce shoes for the user and the identified features.

[0044] Furthermore, when the reception unit 131 receives selection information such as the intended use of the shoes, requests regarding upper materials, requests regarding delivery time, and / or requests regarding costs in addition to the factual information, the calculation unit 132 may select a shoe last model based on the difference amount and the selection information. In detail, the calculation unit 132 refers to the recommended shoe last model database 1108 and selects a shoe last model corresponding to the difference amount and the selection information.

[0045] In the following, the "difference amount" includes not only the difference amount calculated by the calculation unit 132, but also the corrected difference amount when the difference amount is corrected. Furthermore, when there are multiple types of shoe last models corresponding to the recommended shoe last model database 1108, the calculation unit 132 selects all types of corresponding shoe last models.

[0046] The output unit 108 outputs the production data calculated by the calculation unit 132. The output unit 108 may output the shoe last model selected by the calculation unit 132 together with the production data. If the output unit 108 is configured as a display, the production data is displayed on the display. If the output unit 108 is configured as a printer, the production data is output by the printer. If the output unit 108 includes an output interface for outputting to a shoe last making device, the production data is transmitted to the shoe last making device. The production data is output by at least one method of displaying on a display, outputting by a printer, and transmitting to a shoe last making device.

[0047] Here, a description will be given of a plurality of types of shoe last models manufactured by different methods, which are used in the first embodiment. Fig. 4 is a diagram showing an example of a shoe last model. The shoe last models are roughly divided into a first shoe last model and a simple shoe last model.

[0048] The first shoe last model is a solid type shoe last model, which is a model that reproduces the production data calculated by the calculation unit 132 relatively faithfully. The first shoe last model includes, for example, a 3D printer model produced by laminating resin or pulp using a 3D printer, and a cutting machine model produced by cutting hard materials such as wood using a cutting machine. In order to produce a shoe last for a 3D printer model, in addition to a 3D printer, a separate facility for melting resin or pulp may be required in some cases. In addition, a cutting machine is required to produce a shoe last for a cutting machine model.

[0049] On the other hand, the simple shoe last model is easier to make than the first shoe last model, and can be made by a store clerk at the store. As an example, four simple shoe last models (a second shoe last model, a third shoe last model, a fourth shoe last model, and a fifth shoe last model) are shown in FIG. 4.

[0050] The second shoe last model is a model in which an engagement groove is formed in each of a plurality of planar parts, and each planar part is attached to the engagement groove. The planar parts are created by cutting a wooden board such as medium density fiberboard (MDF) with a laser processing machine. The material of the planar parts is not limited to MDF, but may be other wooden boards such as insulation fiberboard (IB) or hard fiberboard (HB). As the IB, A-class insulation board, tatami board, or sheathing board may be used as the material of the planar parts. As the HB, standard board or tempered board may be used as the material of the planar parts. Furthermore, the material of the planar parts is not limited to the above-mentioned wooden board, but may be any material capable of producing a shoe last, such as highly recyclable cardboard, cork, plywood, particle board, metal, or thermoplastic resin. As an example, FIG. 4 shows a planar parts model produced by assembling a plurality of MDF planar parts. To produce a shoe last for the second shoe last model, a cutting machine such as a laser processing machine is required.

[0051] The third shoe last model is a variable model produced by adjusting the adjustment amounts of a plurality of adjustment parts. The third shoe last model is the easiest model to produce among the shoe last models shown in Fig. 4. As an example, Fig. 4 shows a variable model 40. As shown in Fig. 4, the variable model 40 is provided with a plurality of adjustment parts 41 and an adjustment mechanism 42 for adjusting the positions of the adjustment parts 41, so that the positions of the adjustment parts 41 can be changed.

[0052] The fourth shoe last model is a model made by stacking a plurality of three-dimensional parts. As an example, Fig. 4 shows a voxel model (three-dimensional part model) made by stacking a plurality of voxels, which are box-shaped three-dimensional parts. As another example, the fourth shoe last model may be a model made by stacking a plurality of spherical beads, which are spherical three-dimensional parts, or a model made by stacking a plurality of cylindrical beads, which are cylindrical three-dimensional parts.

[0053] The fifth shoe last model is a hybrid model in which different shoe last models are combined. As an example, Fig. 4 shows a model in which only a predetermined area is made of the second shoe last model based on the simplest third shoe last model.

[0054] The predetermined area is an area where the degree of shape coincidence between the user's foot shape and the reference foot shape, or the degree of shape coincidence between the shoe shape used to make the user's shoes and the reference shoe shape, is less than a threshold (for example, an area corresponding to the instep, an area corresponding to the toes, etc.). In the hybrid model shown in Fig. 4, a different shoe shape model is applied to each area based on the degree of shape coincidence between the user's foot shape and the reference foot shape, or the degree of shape coincidence between the shoe shape used to make the user's shoes and the reference shoe shape.

[0055] As another example of a specified area, the specified area may be an area where the curvature of the user's foot shape or the shoe mold used to make the user's shoes is above a threshold (for example, an area corresponding to the instep, an area corresponding to the toes, etc.).

[0056] In the hybrid model shown in FIG. 4, the simplest third shoe last model is applied to the area where the shape coincidence is equal to or greater than the threshold, and the second shoe last model is applied to the area where the shape coincidence is less than the threshold, but this is merely an example. The hybrid model may be a model in which different shoe last models are combined, so it may be a model in which only a predetermined area is made with the fourth shoe last model based on the third shoe last model, or a model in which only a predetermined area is made with the second shoe last model or the fourth shoe last model based on the first shoe last model. The hybrid model may also be a model in which only a predetermined area is made with at least one of the first shoe last model, the second shoe last model, the third shoe last model, and the fourth shoe last model based on an existing shoe last.

[0057] As shown in FIG. 4, each shoe last model has different manufacturing methods and materials, and therefore each shoe last model has different characteristics. Here, the characteristics of each shoe last model will be described. FIG. 5 is a diagram showing an example of the characteristics of each shoe last model. In FIG. 5, "shape reproducibility" means the degree to which the shape of the user's foot can be reproduced by the shoe last, "heat resistance" means the heat resistance of the shoe last, "production time" means the time required to produce the shoe last, and "cost" means the cost required to produce the shoe last.

[0058] In Figure 5, each shoe last model is rated on a 5-point scale for "production time" and "cost," with a higher number being assigned to a shoe last model that takes longer to produce a shoe last, and a higher number being assigned to a shoe last model that costs more to produce a shoe last. The features of each shoe last model are described below.

[0059] The first shoe last model has a feature of high shape reproducibility compared to the simple shoe last model. On the other hand, the first shoe last model tends to take more time and cost to create a shoe last compared to the simple shoe last model.

[0060] The simple shoe last model has an advantage that the time and cost required for making a shoe last can be reduced compared to the first shoe last model.

[0061] The variable model has the advantage that, among the shoe last models shown in FIG. 5, the time required to make the shoe last is the shortest, and the cost required to make the shoe last is also the lowest.

[0062] The two-dimensional part model, the three-dimensional part model, and the hybrid model are positioned intermediately among the shoe last models shown in FIG. 5 in terms of shape reproducibility, the time required to make a shoe last, and the cost required to make a shoe last.

[0063] A two-dimensional part model has a characteristic that the cost of making a shoe last may be higher than that of a three-dimensional part model and a hybrid model. A three-dimensional part model has a characteristic that the time required to make a shoe last may be longer than that of a two-dimensional part model and a hybrid model. A hybrid model can reduce the time and cost required to make a shoe last compared to a two-dimensional part model and a three-dimensional part model.

[0064] Another characteristic is that, compared to other shoe last models, the 3D printer model may have inferior heat resistance depending on the material used. Note that the numerical values ​​shown in FIG. 5 are merely examples. Also, the characteristics shown in FIG. 5 are merely examples, and the characteristics of each shoe last model are not limited to those shown in FIG. 5. The shoe last production assistance device 100 stores a recommended shoe last model database 1108 created based on the characteristics of each shoe last model, and the calculation unit 132 (see FIG. 3) selects a shoe last model by referring to the recommended shoe last model database 1108.

[0065] Fig. 6 is a diagram showing an example of the recommended shoe last model database 1108 according to embodiment 1. As shown in Fig. 6, the recommended shoe last model database 1108 associates conditions with shoe last models recommended under the conditions (models marked with a circle in the figure). The recommended shoe last model database 1108 is referred to when the calculation unit 132 (see Fig. 3) selects a shoe last model.

[0066] In Figure 6, "difference from reference" refers to the amount of difference between the user's foot shape and the reference foot shape, or the amount of difference between the last used to make the user's shoes and the reference last, "delivery time" refers to the number of days the user can wait for the delivery of the shoes, and "cost" refers to the cost of making the shoes.

[0067] The calculation unit 132 is configured to identify corresponding conditions based on information (only factual information, or factual information and selection information) regarding the user's shoes received by the receiving unit 131 (see FIG. 3) and to select a shoe model associated with the identified conditions.

[0068] The recommended shoe last model according to the "difference from the reference" is determined based on the shape reproducibility of each shoe last model, and the greater the difference from the reference, the higher the shape reproducibility of the shoe last model is associated with the shoe last model. As a result, the greater the difference from the reference, the higher the shape reproducibility of the shoe last model is selected.

[0069] The recommended shoe last model according to the "purpose of use" is determined based on the shape reproducibility of each shoe last model, and shoe last models with relatively high shape reproducibility are associated with uses that involve relatively more forward and backward or side-to-side movement (such as soccer, basketball, running, etc.). As a result, when shoes are used for uses that involve relatively more forward and backward or side-to-side movement, shoe last models with relatively high shape reproducibility are selected.

[0070] The recommended shoe last model according to the "upper material" is determined based on the heat resistance of each shoe last model, and shoe last models with high heat resistance are associated with uppers made of heat shrink material. As a result, if you wish to use a heat shrink material for the upper, you can select a shoe last model with high heat resistance.

[0071] The recommended shoe last model according to the "delivery date" is determined based on the production time of each shoe last model, and the shorter the delivery date, the shorter the shoe last model that is associated with it. As a result, if there is a request to receive shoes quickly, a shoe last model that requires a short time to produce a shoe last is selected.

[0072] The recommended shoe last model according to "cost" is determined based on the cost required to produce each shoe last model and the shape reproducibility of each shoe last model, and a shoe last model with low cost required to produce a shoe last is associated with a cost priority, and a shoe last model with high shape reproducibility is associated with a shape reproducibility priority over cost. As a result, when there is a demand for cost priority, a shoe last model with low cost required to produce a shoe last is selected, and when there is a demand for shape reproducibility priority over cost, a shoe last model with high shape reproducibility is selected.

[0073] If the shoe last model selected based on the information on the user's shoes received by the receiving unit 131 is a hybrid model, the calculation unit 132 further determines a combination of shoe last models and an application area. As an example of a determination method, the calculation unit 132 calculates the shape matching degree between the user's foot last and a reference foot last, or the shape matching degree between a shoe last used to make the user's shoes and the reference shoe last, and determines the shoe last model to be applied based on the matching degree. The calculation unit 132 determines the application of a simple shoe last model such as a variable model to an area where the matching degree is equal to or greater than a threshold, and determines the application of a shoe last model with high shape reproducibility to an area where the matching degree is less than the threshold.

[0074] As another example, the calculation unit 132 calculates the curvature of the user's foot shape or a shoe shape used to make the user's shoes, and determines the shoe shape model to be applied based on the curvature. The calculation unit 132 determines the application of a simple shoe shape model such as a variable model to an area where the curvature is less than a threshold, and determines the application of a shoe shape model with high shape reproducibility to an area where the curvature is equal to or greater than the threshold.

[0075] It should be noted that the conditions shown in Fig. 6 and the shoe last models recommended under those conditions are merely examples and are not limited to these. The item names and numerical values ​​of each condition and the application of each shoe last model shown in Fig. 6 are also examples and are not limited to these. In addition, it is sufficient for the recommended shoe last model database 1108 to include a recommended shoe last model according to the "amount of difference from the reference", and it may or may not include recommended shoe last models according to other conditions.

[0076] Furthermore, the recommended shoe last model database 1108 may include recommended shoe last models corresponding to the manufacturing method of the shoes, in addition to the recommended shoe last models corresponding to the conditions shown in Fig. 6. As an example of such a case, when the shoes are manufactured by a method that requires a process of pressing the sole and the upper, the recommended shoe last model database 1108 may be constructed so that a shoe last model with high strength is selected.

[0077] Fig. 7 is a diagram showing an example of production data output by the shoe last production assisting device 100 according to embodiment 1. Upon completion of selection of the shoe last model, the calculation unit 132 (see Fig. 3) calculates and outputs production data corresponding to the selected shoe last model.

[0078] If the selected shoe last model is a 3D printer model, the calculation unit 132 calculates and outputs 3D printer control data, that is, printing data such as STL (Standard Triangulated Language) data, and data on the layering direction.

[0079] If the selected shoe last model is a cutting machine model, the calculation unit 132 calculates and outputs control data for the cutting machine.

[0080] When the selected shoe last model is the second shoe last model, the calculation unit 132 calculates and outputs cross-section data of the shoe last and cutting data for creating flat parts corresponding to each cross-section.

[0081] If the selected shoe last model is the third shoe last model, the calculation unit 132 calculates and outputs the adjustment amount of each adjustment part.

[0082] When the selected shoe last model is the fourth shoe last model, the calculation unit 132 calculates and outputs the number of three-dimensional parts, the size of the three-dimensional parts, and the arrangement (layout) of the three-dimensional parts. The calculation unit 132 may determine the size of the three-dimensional parts to be used according to the shape reproducibility desired by the user.

[0083] When the selected shoe last model is the fifth shoe last model, the calculation unit 132 calculates and outputs the production data required for producing the shoe lasts of each combined shoe last model. As an example, when the selected shoe last model is a model in which the second shoe last model and the third shoe last model are combined, the calculation unit 132 calculates and outputs the cross-section data, the cutting data, and the adjustment amount of each adjustment part.

[0084] When the selected shoe last model is the second shoe last model and the shoes are manufactured by a method that requires a pressure bonding process between the sole and the upper, the calculation unit 132 may make corrections such as increasing the number of flat parts when calculating the manufacturing data, thereby increasing the strength of the shoe last.

[0085] Furthermore, when the selected shoe last model is the fourth shoe last model and the shoes are manufactured by a method that requires a pressure bonding process between the sole and the upper, the calculation unit 132 may make corrections such as increasing the number of three-dimensional parts when calculating the manufacturing data, thereby increasing the strength of the shoe last.

[0086] Fig. 8 is a flow chart showing an example of the processing performed by the shoe last making assisting apparatus 100 according to embodiment 1. A series of processing shown in Fig. 8 is executed by the processor 102 (see Fig. 2).

[0087] In step S805, the processor 102 receives foot last data of the user or shoe last data used to make shoes for the user, which is received via the input unit 106 (see FIG. 2).

[0088] In step S810, the processor 102 accepts the selection information accepted by the input unit 106. If the selection information has not been accepted by the input unit 106, the processor 102 skips the process of step S810 and proceeds to step S815.

[0089] In step S815, when the processor 102 has received the user's foot shape data in step S805, the processor 102 compares the user's foot shape data with the reference foot shape data and calculates the amount of difference between the user's foot shape and the reference foot shape. In addition, when the processor 102 has received the shoe shape data used to make the user's shoes in step S805, the processor 102 compares the shoe shape data used to make the user's shoes with the reference shoe shape data and calculates the amount of difference between the shoe shape used to make the user's shoes and the reference shoe shape data.

[0090] In step S820, the processor 102 selects at least one type of shoe last model according to the difference amount calculated in step S815. If the processor 102 receives selection information in step S810, the processor 102 selects at least one type of shoe last model according to the difference amount calculated in step S815 and the selection information received in step S810.

[0091] In step S825, the processor 102 calculates production data corresponding to the shoe last model selected in step S820.

[0092] In step S830, the processor 102 outputs the production data calculated in step S825. As a result, the production data is displayed on a display provided in the shoe last production assisting device 100. The production data may be output by a printer or may be transmitted to the shoe last production device. In step S830, the processor 102 may output the shoe last model selected in step S820 together with the production data calculated in step S825.

[0093] After step S830, the processor 102 ends the series of processes shown in FIG. In addition, if there are multiple types of shoe last models selected by the processor 102 in step S820, the processor 102 may output all of the selected shoe last models as recommended shoe last models, prompting the worker or user to select a shoe last model, and calculate the production data only for the shoe last model selected by the worker or user.

[0094] 8, the processor 102 selects a shoe last model in step S820, and then calculates and outputs the production data, but it may simply select a shoe last model and output the selected shoe last model. In other words, the shoe last production assisting device 100 may only have a function of presenting a recommended shoe last model, such as selecting a shoe last model that meets the conditions from among a plurality of shoe last models based on information about the user's shoes, and outputting the selected shoe last model.

[0095] In this way, the shoe last production assistance device 100 of embodiment 1 selects at least one shoe last model from multiple shoe last models made using different manufacturing methods based on the received user's foot last data or shoe last data used to produce the user's shoes.

[0096] Furthermore, the shoe last production assistance device 100 according to embodiment 1 can accept selection information in addition to the user's foot last data or the shoe last data used to produce the user's shoes, and selects at least one shoe last model from among multiple shoe last models produced by different manufacturing methods based on the accepted user's foot last data or the shoe last data used to produce the user's shoes and the selection information.

[0097] Therefore, according to the shoe last making assistance device 100 of the first embodiment, the optimum shoe last model that meets the conditions is selected from a plurality of shoe last models, thereby reducing the effort of the worker making the shoe last.

[0098] Furthermore, the shoe last production assisting device 100 according to the first embodiment calculates and outputs production data corresponding to the selected shoe last model. Conventionally, it was necessary to calculate production data using different software or different devices for each shoe last model, but according to the shoe last production assisting device 100 according to the first embodiment, production data corresponding to the selected shoe last model is calculated and output, reducing the burden on the operator.

[0099] [Embodiment 2] In the second embodiment, a description will be given of a shoe last making system including the above-mentioned shoe last making assisting device 100 and a shoe last making device that makes a shoe last using the making data calculated by the shoe last making assisting device 100.

The input unit 406 corresponds to the receiving unit of the shoe last production apparatus 400.

[0106] The output unit 408 is configured with a display or the like, and outputs the processing results from the processor 402, etc.

[0107] The communication controller 420 exchanges data with other control devices, etc., using wired or wireless communication. The shoe last making device 400 receives the making data from the shoe last making assisting device 100 via the communication controller 420.

[0108] The optical drive 412 reads a program stored in a recording medium 414 (e.g., an optical recording medium such as a DVD) that non-transiently stores a computer-readable program, and installs the read program in the storage 410, etc.

[0109] The processing program 4104 executed by the shoe last making apparatus 400 may be installed via a computer-readable recording medium 414, or may be installed by downloading from a server device on a network. The functions provided by the shoe last making apparatus 400 according to the second embodiment may be realized by using some of the modules provided by the OS.

[0110] 10 shows an example of a configuration in which the processor 402 executes a program to provide functions required for the shoe last making device 400, but some or all of these provided functions may be implemented using a dedicated hardware circuit (e.g., ASIC or FPGA, etc.) The configuration of the shoe last making device 400 shown in FIG. 10 is merely an example, and is not limited to this configuration.

Of the processing shown in Fig. 11, steps S1105 to S1130 are executed by the processor 102 of the shoe last making assisting apparatus 100 (see Fig. 2), and steps S1135 and S1140 are executed by the processor 402 of the shoe last making apparatus 400 (see Fig. 10).

[0112] In steps S1105 to S1125, the processor 102 performs the same processes as those in steps S805 to S825.

[0113] In step S1130, the processor 102 transmits the production data calculated in step S1125 to the shoe last making device 400.

[0114] In step S1135, the processor 402 receives the production data from the shoe last production assisting apparatus 100.

[0115] In step S1140, the processor 402 creates a shoe last using the production data received from the shoe last production assistance apparatus 100.

[0116] After step S1140, the shoe last making system 10 ends the series of processes shown in FIG.

[0119] Therefore, according to the shoe last making system 10 of the second embodiment, the most suitable shoe last model that meets the conditions is selected from a plurality of shoe last models, thereby reducing the effort of the worker making the shoe last.

[0120] In addition, in the past, it was necessary to calculate production data for each shoe last model using different software or different devices, and then produce a shoe last using the calculated production data. However, according to the shoe last production system 10 of embodiment 2, production data corresponding to the selected shoe last model is calculated, and the shoe last is produced using the production data, thereby reducing the workload of the worker.
