The user 60 may generate a try-on image through the electronic device 61 and the image of foot and the shoe design data captured by the electronic device 61. In other words, the shoemaking system 100 in another embodiment of the present disclosure may further provide a preview image to the user 60 by Augmented Reality (AR).

In the present embodiment, after providing the purchase data (Step S12) to the user, the shoemaking system 100 asks the user whether or not to produce the designed shoes corresponding to the purchase data through the communication unit 110 (Step S13). If the user submits a negative answer, the shoemaking system 100 immediately stops producing the shoes according to the shoe design data at this time (Step S14).

After the shoemaking system 100 receives the order data (Step S13), the shoemaking system 100 begins to produce the shoes based on the shoe design data through the shoemaking device 150 (Step S15). The shoemaking device 150 uses the upper material and the sole material selected from the shoe design data to produce the designed shoes. At the same time while the designed shoes are produced, the shoemaking method in the present embodiment further generates a tracking tag for each pair of the shoes (Step S16). After producing the shoes, the abovementioned tracking tag is sent to the user together with the designed shoes. The shoemaking system 100 may wait for the tracking information corresponding to the tracking tag in a default time (Step S17). The default time, for example, may be three days after shipping, a week after shipping, etc, determined by the time required for delivery. After the default time is passed, if the shoemaking system 100 hasn't received the tracking information yet, then the shoemaking system may further submit a message to the user to ask for receipt status (Step S18) to ensure that the user indeed receives the designed shoes purchased by the user.

After the shoemaking system 100 receives the tracking information, the order may be completed immediately (Step S19). Through the abovementioned shoemaking method in the present embodiment, the process of user purchasing the shoes may be completed by an automatic service. At the same time, it can be ensured that the user receives the designed shoes purchased by the user, so that a more perfect shoes purchase service is provided.

On the other hand, the shoemaking system and the shoemaking method according to the present disclosure not only may produce the designed shoes by the abovementioned specialized and customized method, but also may provide purchase services to a plurality of users such as group purchase or crowd funding. In another embodiment, the purchase data, for example, includes an estimated fee of production and an estimated time of production. But the purchase data may further include a production fee for group purchase, a production quantity for group purchase, and a production time for group purchase.

In the second embodiment of the present disclosure, the user first provides the shoe design data (Step S21), and the purchase data is provided according to the shoes design data (Step S22). In addition to the estimated fee of production and the estimated time of production calculated according to the stock amount and cost of the sole material and the stock amount and cost of the upper material, the production fee of group purchase and the production time of group purchase calculated by larger quantity of the group purchase may also be added to the purchase data and integrally provided to the user; that is, a providable discounted price is calculated based on the larger quantity and is integrally provided to the users with the purchase data as a reference.

In the present embodiment, the production fee of group purchase may be calculated by a quantity of group purchase, or by a plurality of quantities of group purchase of different ranges, where the corresponding production fee of group purchase is calculated according to the different quantities of group purchase. The present disclosure isn't limited to the method of data presentation for the production fee and the production quantity of group purchase in the purchase data.

Please refer to FIG. 3. The shoemaking system in the present embodiment, after providing the purchase data to the user (Step S22), may first ask the user, for example, through the operation interface of the webpage or the application whether or not the user would like to make a group purchase (Step S23). If the user submits the command of denying, the shoemaking system asks the user whether or not the shoes need to be produced by a specialized or customized method (Step S24). If the user submits the command of denying production again, then the shoemaking method used in the shoemaking system in the present embodiment may stop the process of purchasing and shoemaking according to the shoes design data immediately (Step S25). If the user just needs to produce an individual quantity of shoes that is required for the user by the specialized or customized method, the order data may be submit immediately to make the shoemaking system produce the designed shoes (Step S27).

When the shoemaking system in the present embodiment receives the command from the user to confirm production, the shoemaking system begins to gather the quantity for group purchase openly (Step S26). In particular, the shoemaking system in the present embodiment uploads the shoes design data to a digital tally platform. The digital tally platform, for example, may be a social networking site or a group purchase website, and the digital tally platform lets other users or browsing users select whether or not to join in the group purchase through the social networking site or the group purchase website. In the step S26 of gathering quantities of group purchase, the shoemaking system may produce the designed shoes immediately after the quantity of group purchase achieves a default quantity (Step S27). The quantities of group purchase may be gathered by setting a regular tally time. The designed shoes are produced according to the final tally quantity, but the present disclosure isn't limited thereto.

After completing the step S27 of producing the designed shoes, the shoemaking system in the present embodiment generates a tracking tag corresponding to each pair of shoes (Step S28), and confirms whether or not to receive the tracking information generated by the tracking tag corresponding to the purchased shoes (Step S29). If the tracking information hasn't been received, the receipt status corresponding to the buyer is asked immediately (Step S210). If the tracking information is received, the order corresponding to the designed shoes may be completed immediately (Step S211).

Through the abovementioned shoemaking method in the present embodiment, when the user selects the method of group purchase, as the quantity of group purchase is increased, the production fee of the designed shoes is then decreased, and the shoemaking system may calculate the corresponding discount value and the cost of production saved after mass production as a reference for the maker of the shoemaking system after gathering the quantities of group purchase(Step S26), but the present disclosure isn't limited thereto.

Based on the shoemaking system and the shoemaking method of the abovementioned embodiment, the shoemaking system and the shoemaking method according to the present disclosure not only may provide an automatic shoemaking method, but also may further provide a customized shoemaking service to the users. At the same time, when the users want to further reduce the price, a large lot of production may be achieved by group purchase or crowd funding to reduce the prices.

On the other hand, in another embodiment of the present disclosure, the shoemaking system may further compare the data of the existing shoes to the shoe design data. FIG. 4 is a flowchart of the shoemaking method in the third embodiment of the present embodiment. Please refer to FIG. 4. In the shoemaking method in the third embodiment of the present disclosure, after the shoemaking system obtains the shoe design data through the communication unit (Step S31), the shoe design data is compared to the data of a plurality of existing shoes in the shoes database (Step S32). For example, the shoemaking system searches whether there is a combination of the upper data and the sole data of these shoes data in the shoes database that is the same as or similar to the shoe design data (Step S33). If existing designed shoes similar to the shoe design data are found, a message is provided to the electronic device of the user through the communication unit to let the user reference the existing designed shoes (Step S34). Related information such as the production fee and the production time of the existing designed shoes are also provided at the same time, and the shoemaking system asks the user whether or not to produce the shoes based on the existing designed shoes (Step S35). If the shoemaking system receives from the user a command to confirm production, the designed shoes may begin to be produced immediately (Step S36).

In the present embodiment, if there is no existing shoes data in the shoes database that is the same as or similar to the shoe design data provided by the user, or if the user chooses not to produce the designed shoes based on the data of the existing shoes, then the shoemaking system in the present embodiment provides the purchase data to the user as a reference (Step S37), and waits for the user to indicate whether or not to submit the order data (Step S38). If the user submits the command of denial, the purchase is canceled immediately (Step S39). If the user submits the order data, the designed shoes begins to be produced immediately (Step S36). As mentioned above, the shoemaking method and the shoemaking system in the embodiment of the present disclosure not only may produce the shoes according to the design request of each user, but also may compare the existing designed shoes with the products in the stock, and gives the user more selections. The speed of production and the delivery may be accelerated by having the existing designed shoes and the products in the stock, and the cost of production may be reduced to promote selling the products at the same time.

Please refer to a side view of the first pickup device 153 shown by FIG. 6, wherein the first pickup device 153 further includes the image capture unit 1532. When the upper 70 is set on the shoe last 71 and captured by the four claws 1531, the first pickup device 153 will first move the upper 70 and the shoe last 71 to allow the image capture unit 1532 to capture the image. The processing unit 151 may calculate the position of a mounting hole 72 of the shoe last 71 relative to the four claws 1531 according to the image captured by the image capture unit 1532, and provide a position command to the first pickup device 153. The first pickup device 153 makes the mounting hole of the shoe last 71 set on the upper 70 correspond to the first support 1521A according to the abovementioned position command, so that the upper 70 and the shoe last 71 may be disposed on the first support 1521A, and moved through the first plate 1522 of the first conveying device 152.

The shoemaking system of the present disclosure not only may automatically process the upper, but also further processes the sole automatically. FIG. 7 is a diagram of a device of the shoemaking system in the fourth embodiment of the present disclosure. Please refer to FIG. 7. In the fourth embodiment of the present disclosure, the shoemaking device 250, similar to the shoe making device 150, includes the processing unit 251, and the first conveying device 252 connected to the processing unit 251, the first pickup device 253, the scanning device 254, the first coating device 255 and the first applying device 256. The first conveying device 252 sequentially moves the upper 80 obtained from the first pickup device 253 to the scanning device 254, the first coating device 255 and the first applying device 256. The shoemaking device of the present embodiment further includes the second conveying device 262, the second coating device 265 and the second applying device 266. An operator, for example, may dispose the sole 90 on the second conveying device 262. The second conveying device 262 sequentially moves the sole 90 to the scanning device 254, the second coating device 265 and the second applying device 266.

When the sole 90 is moved to the scanning area D of the scanning device 254 by the second conveying device 262, the scanning device 254 scans the upper 90 to obtain three-dimensional structure data. The processing unit 251 decides a second coating path and a second applying path based on the three-dimensional structure data. When the second conveying device 262 moves the sole 90 to the second coating device 265, the second coating device 265 sprays the second treating agent to the sole 90 according to the second coating path; when the second conveying device 262 moves the sole 90 to the second applying device 266, the second applying device 266 applies the second adhesive to the sole 90 according to the second applying path. Through the first conveying device 252, the first coating device 255 and the first applying device 256, the upper 80 may be coated with the first adhesive. Through the second conveying device 262, the second coating device 265 and the second applying device 266, the sole 90 may be applied by the second adhesive. The upper 80 and the sole 90 may be combined by the first adhesive and the second adhesive.

In particular, the second conveying device 262 of the present embodiment further includes a second plate 2622. The second plate 2622 is configured to carry the sole, and the second plate 2622 in the present embodiment, for example, may further comprise a plate 2621. The sole 90 may be disposed on the plate 2621. The second plate 2622 substantially extends along a plane, and the second plate 2622 rotates about the rotation axis 2623 perpendicular to the plate. The second conveying device 262 moves the sole 90 by rotating the second plate 2622.

Furthermore, the first plate 2522 of the first conveying device 252 in the present embodiment is rotatable about the direction d1, and the second plate 2622 of the second conveying device 262 is rotatable about a direction d2. Thus the first conveying device 252 and the second conveying device 262 may move the upper 80 and the sole 90 to the scanning area D to be scanned together at the same time. As such, the three-dimensional structure data may include a three-dimensional structure corresponding to the upper 80 and the sole 90 at the same time.

Please refer to FIG. 7. On the other hand, the second coating device 265 may spray the second treating agent in the second coating area E. The second applying device 266 is configured to spray the second adhesive in the second applying area F. The second coating area E and the second applying area F are distributed on the second plate 2622, hence the second plate 2622 may immediately and sequentially moves the sole 90 to the scanning area D, the second coating area E, and the second applying area F by rotating.

Please refer to FIG. 8. In the present embodiment, the abovementioned shoemaking device 250 further includes a heating device 272, a cooling device 273 and a cleaning device 274. After operators P1-P3 combine the upper 80 and the sole 90 to form a shoe 81, the shoe 81 is set on a conveyor 271. The heating device 272 heats the shoe 81, the cooling device 273 cools the shoe 81 heated by the heating device 272, so that the connection between the upper 80 and the sole 90 is further enhanced. The cleaning device 274 further cleans the shoe 81 after the shoe 81 is cooled. The shoemaking device 250 may further comprise a packing device 275. The cleaned shoe 81 may form a product 82 through the packing device 275 to be prepared for shipment. As mentioned above, for example, the tracking tag may also be disposed on the product 82 in the packing device 275. The shoemaking device of the present embodiment 250 may further automatically complete producing the shoe 81 through the abovementioned device. However, the heating device, the cooling device, the cleaning device and the packing device may be disposed according to the needs, and the present disclosure isn't limited thereto.

As mentioned above, the shoe making device 150 and 250 in the embodiment of the present disclosure may automate the processing of the upper, and the needs for space is decreased. A plurality of shoemaking device 150 are set in a factory building as a plurality of working stations to enhance the efficiency of the shoemaking. The shoemaking device 250 may further process the sole, then the shoemaking process may be completed effectively by automation technologies. Thus, the shoe making device 150 may provide an automated process with further space saving.

In the following sentence, the scanning method and the coating method in the embodiment of the present disclosure are further described in detail according to the scanning device, the first coating device and the first coating path. The coating method and the coating device according to the present disclosure are not limited to the scanning devices 154 and 254, and the first coating devices 155 and 255, and the second coating device 265. The coating method according to the present disclosure may further be applied to the independently disposed scanning device and coating device, and may further be the scanning device and the coating device integrally disposed with another device, the present disclosure isn't limited thereto. In the following, examples will be described using the scanning device 154 and the first coating device 155.

FIG. 9A is a vertical diagram of the upper in the embodiment of the present disclosure; FIG. 9B is a diagram of the three-dimensional structure data of the upper of FIG. 9A. Please refer to FIG. 9A, herein the surfaces 73 and 74, for example, may be a lower surface configured to bind the upper to the sole. In particular, for example, they may be midsoles of an upper of the present embodiment. After the surfaces 73 and 74 are scanned by the scanning device 154, the three-dimensional structure data may be obtained. The three-dimensional structure data of the present embodiment, for example, may be formed by Structured Light, that is, it is formed by sequentially scanning with laser of different sizes. The light spots of different sizes will be formed in the three-dimensional structure data based on the pixels of different sizes. The scanning results obtained by laser beam of three different sizes are taken as examples in the following sentences, but the present disclosure isn't limited thereto. In particular, when the scanning device 154 scans the surface 73 with the widest light beam, for example, the scanning result formed by the pixel 91 may be obtained; when the scanning device 154 scans the surface 73 with the second widest light beam, for example, the scanning result formed by the pixel 92 may be obtained; when the scanning device 154 scans the surface 73 with the narrowest light beam, for example, the scanning result formed by the pixel 93 may be obtained. Through the abovementioned method, the scanning method used in the present embodiment may obtain the three-dimensional structure data Data1 according to the surface 73 and may obtain the three-dimensional structure data Data2 according to the surface 74.

Based on the three-dimensional structure data Data1 and Data2, the coating method of the present embodiment may directly determine a coating path. The coating method in the present embodiment moves the position of the nozzle relative to the surface of the object according to the positions of the pixels. FIGS. 10A and 10B are diagrams of an embodiment of the coating device spraying a surface. Please refer to FIG. 10A. The processing device may immediately decide the position of a nozzle 1551 of the first coating device 155 according to the position of the pixels in the three-dimensional structure data Data1 and Data2. Such position is preferably a center position, which makes the nozzle 1551 of the first coating device 155 face a position X1 on the surface 73 to which one of the pixels corresponds.

The coating method of the present embodiment may decide the distance between the nozzle 1551 and the surface 73 of the object according to the size of the pixels. Please refer to FIG. 10A. In particular, when the pixel area is larger, the distance between the nozzle 1551 and the surface 73 of the object H1 may be increased, and the surface 73 is coated with the larger width W1. Please refer to FIG. 10B. When pixel area is smaller, the distance between the nozzle 1551 and the surface 73 of the object may be decreased, and the surface 73 is coated with the narrower width W2. In other words, when the three-dimensional structure data Data1 is obtained through the abovementioned scanning device, the coating method of the present embodiment also decides a nozzle path of the coating device at the same time, and the process of calculating the large amount of path is eliminated.

In particular, in the coating method of the present embodiment, the processing unit of the first coating device 155 itself or the processing unit connected to the first coating device 155 may first determine a default distance according to the depth data of the three-dimensional structure data, and set a default value to compare with the size of the pixels. When the coating path is modified according to the three-dimensional structure data, if the pixel size of the three-dimensional data is larger than the default value, the distance between the position of the nozzle corresponding to the pixel and the surface is increased; if the pixel size of the three-dimensional data is smaller than the default value, the distance between the position of the nozzle corresponding to the pixel and the surface is decreased. Through the abovementioned modification method, the coating method in the present embodiment may efficiently decide the coating path.

On the other hand, the length of time of the nozzle 1551 spraying the surface 73 of the object may also be decided according to the pixel size. Please refer to FIG. 10A. When the pixel size is larger, the first coating device 155 generates a command of a longer coating time corresponding to the pixel; when the pixel size is smaller, the first coating device 155 generates the command of a shorter coating time corresponding to the pixel. Through the abovementioned method, the coating method in the present embodiment not only may efficiently generate a moving path of the nozzle 1551 of the first coating device 155, but also may uniformly coat the surface 73.

The coating method of the present embodiment may further quickly generate an efficient moving path according to the position of the pixels in the three-dimensional structure data. FIG. 11 is a diagram of the pixel and the coating path in the embodiment of the present disclosure. In particular, please refer to FIG. 11. The processing unit connected to the first coating device 155 may move the nozzle of the first coating device 155 according to paths R1, R2 calculated based on the positions of the pixels 91, 92, and 93 in the three-dimensional structure data, preferably, based on the center positions of the pixels 91, 92, and 93 in the three-dimensional structure data. Furthermore, the first coating device 155 of the present embodiment and the processing unit connected to it may further respectively set the corresponding moving path according to the arrangement of the pixels 91, 92, 93.

Taking the present embodiment as an example, a rectangular range in which the two largest pixels 91 are arranged vertically is taken as a unit. All of the arrangement patterns of the pixels 91, 92, and 93 in the rectangular range are limited. A fixed moving path may be recorded for each of the arrangement, and the coating paths of the whole surface are put together as a table, so that an efficient coating method is provided.

The coating method and the coating device in the embodiment of the present disclosure are not limited to being used with coating treating agents. In another embodiment, they may be further applied to adhesives, spray paint, etc., and the present disclosure isn't limited thereto.

In summary, the shoemaking method and the shoemaking system according to the embodiment of the present disclosure automates the processing of uppers, accelerating the production of shoes by the automation and saving the cost of manpower at the same time. The shoemaking method and the shoemaking system of the embodiment of the present disclosure can further automate the processing of soles, decreasing the need for manpower for the process of bonding a sole and a upper. The shoemaking system of the embodiment of the present disclosure can also save space. A plurality of work stations may be set up in a factory building for work to be conducted at the same time, so that the efficiency of production is also enhanced.
