Description

This disclosure relates to a shoe last making assistance device and a shoe last making system.

When custom-made shoes are made to fit a user's feet, the foot shape is measured with a measuring device, and shoe last data is generated based on the measured foot last data. A shoe last for making the shoes is then created based on the generated shoe last data (for example, Patent Document 1).

Patent No. 6685303

Traditionally, shoe molds for making custom-made shoes 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 using a variety of manufacturing methods have been developed. In this disclosure, a model name is given to each shoe mold made using a different manufacturing method, and for example, a shoe mold made using a cutting machine is referred to as a cutting machine model, and a shoe mold made using a 3D printer is referred to as a 3D printer model. These models of shoe molds made using different manufacturing methods are collectively referred to as shoe mold models.

When there are multiple shoe last models made using different manufacturing methods, it is necessary to select the most suitable shoe last model by considering conditions such as the precision, cost, and manufacturing time of the shoes to be manufactured. However, experience and know-how are required to select the most suitable shoe last model that meets the conditions from multiple shoe last models made using different manufacturing methods, which places a heavy burden on the worker who makes the shoe lasts.

[First embodiment]
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.

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

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 support device 100, or may be installed in a store different from the shoe last making support 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 at a manufacturer and stores the user's personal information, the user's shoe purchase history, shoe last data of existing shoes, and shoe last data created by the user last time.

The shoe last manufacturing 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 shoe last model from among a plurality of shoe last models manufactured 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 used as shoe last models. Details of each shoe last model will be described later with reference to Figures 4 and 5.

Furthermore, the shoe last production support device 100 calculates the production data (described later with reference to FIG. 7) required to produce a shoe last corresponding to the selected shoe last model, and displays the calculated production data on the display 150.

The shoe last production support device 100 may receive shoe last data used to produce the user's shoes, and select at least one shoe last model from among multiple shoe last models with different manufacturing methods based on the received shoe last data. In this case, the shoe last production support device 100 obtains 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.

The shoe last production support device 100 may also output the production data using a printer, or may transmit the production data to a shoe last production device 400 that can communicate with the shoe last production support device 100.

Fig. 2 is a schematic diagram showing an example of the hardware configuration of the shoe last production support device 100 according to the first embodiment. With reference to Fig. 2, the shoe last production support 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.

The processor 102 is composed of a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit), and can read out programs (for example, an OS (Operating System) 1102 and a processing program 1104) stored in the storage 110, and deploy and execute them in the main memory 104. 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 shoe last production data 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 support device 100.

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

In addition to an OS 1102 for implementing basic functions, the storage 110 stores a processing program 1104 for providing the functions of the shoe last production support device 100. That is, the processing program 1104 is executed by the processor 102 of the shoe last production support device 100 to select a shoe last model and calculate production data for the shoe last according to the selected shoe last model. In addition, the storage 110 stores a foot last database 1106, a shoe last database 1107, and a recommended shoe last model database 1108.

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.

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.

The recommended shoe last model database 1108 stores recommended shoe last models by condition. 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. 6.

In addition, the foot shape database 1106 and the shoe shape 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 shape database 1106 and the shoe shape database 1107 may store only lists, and multiple pieces of foot shape data and multiple pieces of shoe shape data themselves may be stored in the data server 500.

The input unit 106 accepts information about 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 accepts information from the measuring device 200, the mobile terminal 300, or the data server 500. The input unit 106 also includes a keyboard, mouse, microphone, touch device, etc. for accepting information. The input unit 106 that accepts information about the user's shoes corresponds to the acceptance unit of the shoe last making assistance device 100.

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 the processing results 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 production device.

The communication controller 120 exchanges data with other control devices, etc., using wired or wireless communication. The shoe last production support 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 support device 100 may also receive shoe last data from the data server 500 via the communication controller 120. The shoe last production support 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.

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.

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

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

Figure 3 is a diagram showing an example of the functional configuration of the shoe last production support device 100 according to the first embodiment. The shoe last production support device 100 includes a receiving unit 131, a calculating unit 132, and an output unit 108.

The reception unit 131 is realized by the input unit 106 described above. 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").

The factual information is the user's foot shape data, or shoe shape data used to make shoes for the user. The user's foot shape data 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.

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.), a request regarding the height of the opening, etc. 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, how much the shoes should cost to make.

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

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 that is 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 shape model database 1108 and selects a shoe shape model that corresponds to the difference. The calculation unit 132 calculates production data required to produce a shoe shape corresponding to the selected shoe shape model based on the user's foot shape data.

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 similar to the received 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.

When the reception unit 131 receives a request (selection information) regarding the shape of the shoes in addition to 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.

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 the user's shoes and the user's requests regarding the shape of the shoes.

In addition, when the receiving unit 131 receives information (selected information) about shoes the user is currently wearing or shoes the user has worn in the past in addition to the factual information, the calculation unit 132 may identify the tendency of the user's feet (wide feet, 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.

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 the user's shoes and the identified features.

In addition, if the reception unit 131 has received 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 that corresponds to the difference amount and the selection information.

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.

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 that outputs to a shoe last production device, the production data is transmitted to the shoe last production device. The production data is output by at least one of the following methods: display on a display, output by a printer, and transmission to a shoe last production device.

Here, we will explain the multiple types of shoe last models that are manufactured using different methods and are used in the first embodiment. Figure 4 is a diagram showing an example of a shoe last model. The shoe last models are broadly divided into a first shoe last model and a simple shoe last model.

The first shoe last model is a solid type shoe last model, and is a model that relatively faithfully reproduces the production data calculated by the calculation unit 132. The first shoe last model includes, for example, a 3D printer model produced by layering 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 some cases, separate equipment for melting resin or pulp is required in addition to the 3D printer. Also, in order to produce a shoe last for a cutting machine model, a cutting machine is required.

In contrast, 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, FIG. 4 shows 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).

The second shoe mold 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 mold, such as highly recyclable cardboard, cork, plywood, particle board, metal, or thermoplastic resin. As an example, FIG. 4 shows a planar part model that is made by assembling multiple MDF planar parts. To make the shoe mold for the second shoe mold model, a cutting machine such as a laser processing machine is required.

The third shoe last model is a variable model that is created by adjusting the adjustment amounts of multiple adjustment parts. The third shoe last model is the easiest model to create 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 multiple 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.

The fourth shoe mold model is a model created by stacking multiple three-dimensional parts. As an example, FIG. 4 shows a voxel model (three-dimensional part model) created by stacking multiple voxels, which are box-shaped three-dimensional parts. As another example, the fourth shoe mold model may be a model created by stacking multiple spherical beads, which are spherical three-dimensional parts, or a model created by stacking multiple cylindrical beads, which are cylindrical three-dimensional parts.

The fifth shoe last model is a hybrid model that combines different shoe last models. As an example, FIG. 4 shows a model based on the simplest third shoe last model, with only a specific area made from the second shoe last model.

The specified area is an area where the degree of shape match between the user's foot shape and the reference foot shape, or the degree of shape match 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 match between the user's foot shape and the reference foot shape, or the degree of shape match between the shoe shape used to make the user's shoes and the reference shoe shape.

As another example of a predetermined area, the predetermined 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 equal to or greater 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, the simplest third shoe last model is applied to areas where the degree of shape matching is equal to or greater than a threshold, and the second shoe last model is applied to areas where the degree of shape matching is less than the threshold, but this is merely one example. The hybrid model may be a model in which different shoe last models are combined, so it may be a model based on the third shoe last model, with only a specified area made with the fourth shoe last model, or a model based on the first shoe last model, with only a specified area made with the second shoe last model or the fourth shoe last model. The hybrid model may also be a model based on an existing shoe last, with only a specified area 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.

As shown in Figure 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 explained. Figure 5 is a diagram showing an example of the characteristics of each shoe last model. In Figure 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.

In Figure 5, each shoe last model is rated on a 5-point scale for "production time" and "cost," with higher numbers being assigned to shoe last models that take longer to produce and higher numbers being assigned to shoe last models that cost more to produce. The features of each shoe last model are explained below.

The first shoe last model has the characteristic of being highly shape reproducible compared to the simple shoe last model. On the other hand, compared to the simple shoe last model, the first shoe last model tends to take more time and cost to create.

The simplified shoe last model has the advantage that it can reduce the time and cost required to create a shoe last compared to the first shoe last model.

The variable model has the advantage that it takes the shortest time to create a shoe last among the shoe last models shown in Figure 5, and also has the lowest cost to create the shoe last.

The two-dimensional part model, three-dimensional part model, and hybrid model are in the middle of the shoe last models shown in Figure 5 in terms of shape reproducibility, time required to make the shoe last, and cost required to make the shoe last.

A two-dimensional part model has the 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 the 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.

Other characteristics of the 3D printer model include the possibility that it may have inferior heat resistance depending on the material used, when compared to other shoe last models. 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 support 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.

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

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 shoe shape used to make the user's shoes and the reference shoe shape, "delivery time" refers to the number of days the user can wait for the delivery of the shoes, and "cost" refers to the cost involved in making the shoes.

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

The recommended shoe last model according to the "difference from the standard" is determined based on the shape reproducibility of each shoe last model, and the greater the difference from the standard, the higher the shoe last model's shape reproducibility is associated. As a result, the greater the difference from the standard, the higher the shoe last model's shape reproducibility is selected.

The recommended shoe last model according to "use purpose" 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, a shoe last model with relatively high shape reproducibility is selected.

The recommended shoe last model for each "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. This means that if you wish to use a heat shrink material for the upper, a shoe last model with high heat resistance will be selected.

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. This allows a shoe last model that takes less time to produce a shoe last to be selected if there is a request to receive shoes quickly.

The recommended shoe last model according to "cost" is determined based on the cost of producing each shoe last model and the shape reproducibility of each shoe last model, and shoe last models with low cost of producing a shoe last are associated with a focus on cost, and shoe last models with high shape reproducibility are associated with a focus on shape reproducibility over cost. As a result, when there is a demand for cost-first preference, a shoe last model with low cost of producing a shoe last is selected, and when there is a demand for shape reproducibility over cost, a shoe last model with high shape reproducibility is selected.

When 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 degree of shape match between the user's foot last and a reference foot last, or the degree of shape match between the 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 degree of match. The calculation unit 132 determines the application of a simple shoe last model such as a variable model to areas where the degree of match is equal to or greater than a threshold, and determines the application of a shoe last model with high shape reproducibility to areas where the degree of match is less than the threshold.

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

Note 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.

The recommended shoe last model database 1108 may also include recommended shoe last models according to the manufacturing method of the shoes, in addition to the recommended shoe last models according to the conditions shown in FIG. 6. As an example of such a case, when shoes are manufactured using a method that requires a crimping process of 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.

Figure 7 is a diagram showing an example of production data output by the shoe last production assistance device 100 according to embodiment 1. When the selection of the shoe last model is completed, the calculation unit 132 (see Figure 3) calculates and outputs production data corresponding to the selected shoe last model.

When the selected shoe last model is a 3D printer model, the calculation unit 132 calculates and outputs the 3D printer control data, i.e., printing data such as STL (Standard Triangulated Language) data, and stacking direction data.

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

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

When 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.

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.

When the selected shoe last model is the fifth shoe last model, the calculation unit 132 calculates and outputs the production data required to produce 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, cutting data, and the adjustment amount of each adjustment part.

When the selected shoe last model is the second shoe last model and the shoes are manufactured using 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. This can increase the strength of the shoe last.

In addition, when the selected shoe last model is the fourth shoe last model and the shoes are manufactured using 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. This can increase the strength of the shoe last.

Figure 8 is a flowchart showing an example of processing performed by the shoe last production support device 100 according to embodiment 1. The series of processing shown in Figure 8 is executed by the processor 102 (see Figure 2).

In step S805, the processor 102 receives the user's foot shape data or shoe shape data to be used in making the user's shoes, which is received by the input unit 106 (see FIG. 2).

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.

In step S815, if 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, if the processor 102 has received shoe shape data to be used in making the user's shoes in step S805, the processor 102 compares the shoe shape data to be used in making the user's shoes with the reference shoe shape data and calculates the amount of difference between the shoe shape to be used in making the user's shoes and the reference shoe shape.

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.

In step S825, the processor 102 calculates manufacturing data corresponding to the shoe last model selected in step S820.

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 assistance 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.

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.

In the series of processes shown in FIG. 8, the processor 102 selects a shoe last model in step S820, and then calculates and outputs the production data, but it is also possible to simply select a shoe last model and output the selected shoe last model. In other words, the shoe last production assistance 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 multiple shoe last models based on information about the user's shoes, and outputting the selected shoe last model.

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

The shoe last manufacturing support device 100 according to the first embodiment can receive selection information in addition to the user's foot last data or the shoe last data used to manufacture the user's shoes, and selects at least one shoe last model from among multiple shoe last models manufactured using different manufacturing methods based on the received user's foot last data or the shoe last data used to manufacture the user's shoes and the selection information.

Therefore, according to the shoe last manufacturing support device 100 of the first embodiment, the optimal shoe last model that meets the conditions is selected from among multiple shoe last models, thereby reducing the effort of the worker who manufactures the shoe last.

The shoe last production support 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 support 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 worker.

Figure 10 shows an example of a configuration in which the processor 402 executes a program to provide the 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). Also, the configuration of the shoe last making device 400 shown in Figure 10 is an example, and is not limited to this configuration.

Figure 11 is a flowchart showing an example of processing performed by the shoe last making system 10 according to embodiment 2. Of the processing shown in Figure 11, steps S1105 to S1130 are executed by the processor 102 of the shoe last making assistance device 100 (see Figure 2), and steps S1135 and S1140 are executed by the processor 402 of the shoe last making device 400 (see Figure 10).

In steps S1105 to S1125, the processor 102 performs the same processing as in steps S805 to S825.

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

In step S1135, the processor 402 receives production data from the shoe last production assistance device 100.
