Description

Ship manufacturing process for the implementation of a smart factory {SHIP MANUFACTURING PROCESS FOR REALIZING SMART FACTORY}

The present invention relates to the production process of the ship manufacturing process, more specifically, based on the information provided in the design, re-processing appropriately for the production environment, DB for various data generated in the re-processing process and manage by production shop, It is related to the shipbuilding process for the implementation of a smart factory that can establish an initial production plan based on the preceding information and enable each process to respond organically when a variable occurs.

In general, in the shipbuilding process, the design performs modeling by reflecting various preceding information delivered in the form of a hard copy, and generates and transmits information for production based on this.

However, various information is generated depending on the production environment.Each data exists individually, making it difficult to effectively manage it, and establishing a production plan based on the information provided in the initial design and responding appropriately when various variables occur. There is a difficult aspect.

For example, referring to Figure 1, the shipbuilding process according to the prior art will be described below.

First, design data for each line is generated and transmitted based on the member information stored in the design information DB 10 (S11). Here, the design information is modeled using shipbuilding-specific 3D modeling software input into the design information DB (10), for example, information is extracted based on Tribon Modeling or AM modeling, and design data for each line is generated. And for transmission (S11), the necessary information is different depending on the workshop (production shop), and this causes data to exist for each line in the production of multiple series lines within the same ship.

Thereafter, a production plan is established based on the transmitted information (S12) and a production operation is performed (S13).

Here, in the overall shipbuilding process, the design participates proactively and the production plays a role to assist with this. In case of establishing a plan for each transmission based on the initially provided design information, if the design quantity changes or the preceding process is delayed in the middle In the case, inconsistency between the plan and the performance information occurs, and the problem of accumulation and loss of waiting time is often caused.

Subsequently, feedback generated in the production process is transmitted to the design part in the form of a wired call or field improvement request form, and after reviewing the request, the design part judges whether it is reflected (S15) and selects the applicable line to determine the result. Reply to production and apply to complete the production operation (S16).

Therefore, as described above, information management methods are different for each design source, history management is difficult due to information change, and it is difficult to respond appropriately in the absence of a person in charge, and various variables such as design quantity changes or prior schedule delays that occur after establishing a production plan are accumulated. As a result, it adversely affects the entire ship manufacturing process, and production information varies depending on the production shop, so there is a problem that design information exists for each line.

Referring to Figure 2, the ship manufacturing process for the implementation of a smart factory according to the present invention, as a whole, for ship construction, design integration DB input step (S110), design information transfer DB storage step (S120), production information Generation step (S130), information integrity check step (S140), production shop-specific data management step (S150) and feedback step (S160), production plan establishment step (S170), and production line-specific production operation step (S180) And, including the production operation feedback step (S190), the main point is to create, manage and apply production information that can organically respond to changes in the manufacturing environment according to design information.

First, in the design integration DB input step (S110), a design schedule is established and stored according to a standard plan for ship building or ship manufacturing, and various preceding information is reflected in modeling and stored, and production technology data is designed and integrated. (110).

Here, the modeling may include the structural member model storage DB (database for the entire structure stored after member modeling), which is a data DB of shipbuilding-specific 3D modeling software, such as Tribon or AM mentioned above. Production technical data may include block division, main plate processing tips, scaffolding, TEMP.ACC.HOLE, welding shrinkage, or LIFT'G PLAN (lifting plan) data.

Next, in the design information transmission DB storage step (S120), according to the information transmitted from the design integrated DB 110, design data and 3D model information are generated and stored in the design information transmission DB 120.

Here, the design information may include member shape information and member attribute information. Specifically, the design information, as shown at the top of FIG. 3, material, thickness, weight, area, shape, and bending information Curved modeling including part information, weld angle and joint length, margin and excess and variance increase, and pin jig information and template modeling) information.

Next, in the production information generation step (S130), an assembly line (assembly symbol) is assigned to each piece of design information transmitted from the design information transmission DB 120, and the assembly line is executed by performing auto nesting. And production information for each thickness. Here, the production information may include member shape information and member attribute information.

Specifically, the production information generation step (S130), as shown at the bottom of FIG. 3, the step of granting the assembly line for each member (S131), and executing the auto nesting (S132), and the assembly line and It consists of the step of placing the members by thickness (S133) and the step of generating information by assembly line and thickness based on the material ordering information and cutting information (S134), but the cutting information includes cutting file, material and thickness and weight. And member information including marking information, cutting and marking length, and cutting and marking idling length.

Next, in the information integrity check step (S140), the information integrity or information consistency of the design information and the production information of the design information transmission DB 120 is checked, and production technology data and production information input to the design integration DB 110 are checked. Check the information integrity or information consistency.

Next, in the data management step for each production shop (S150), if the information consistency between the design information and the production information and the information technology information and the production information are consistent, the design information and production information is transmitted to the production information DB 130 It manages data for each production shop.

For example, as shown in FIG. 7, the production information DB 130 is produced in-house production information 131 for line 1 (No.01) produced in a domestic in-house production shop and in a domestic outside production shop. It includes outside production information (132) for line 2 (No.02) and foreign production information (133) for line 3 (No.03) produced in an overseas production shop, and the line is connected through an internal communication network. Information about and production information DB 130 may share information with each other.

Alternatively, in the feedback step (S160), as shown in FIG. 4, if the information matching of the design information and the production information, or the information matching between the production technology data and the production information (if the information is mismatched) (S161, S162) , After reporting the inconsistency information (S163), the subject of information incompatibility is identified and fed back (S164).

For example, if information inconsistency is inconsistent, and if the subject of information incompatibility is design information, it is corrected and transmitted to the design information transmission DB 120 (S165). If the subject of information incompatibility is production information, it is corrected to produce information DB 130. If the subject of information incompatibility is the production technology information, it is corrected and transmitted to the design information transmission DB 120 (S167) for input and feedback.

Next, in the production plan establishment step (S170), an initial production plan or a subsequent production plan is established according to the prior information corresponding to the reference plan, production information, and process status information for each production shop.

For example, as shown at the top of FIG. 5, the production plan determines the production shop, establishes the production schedule, establishes the initial production plan (S171), and subsequently determines that it is necessary to modify the production plan when changing the preceding information. If it is, the production shop or production schedule is changed to establish a subsequent production plan (S172), and production by transmission line is performed according to the initial production plan or the subsequent production plan.

On the other hand, the change of the production shop and the change of the production schedule can affect each other in both directions and affect the process rate for each line.

Next, in the production operation step for each line (S180), the production operation for each line is performed according to the established production plan.

Here, as shown at the bottom of FIG. 5, the production process rate for each transmission line is checked (S181), and if it is determined that the production plan needs to be modified, the production shop or production schedule is changed (S182), and production for each transmission line is performed. Steps may be repeatedly performed at a specific process rate or at a specific production process (S183), and if it is determined that the production plan is not required to be modified, a step of immediately performing production by transmission line may be repeatedly performed at a specific process rate or at a specific production process. (S183).

Next, in the production work feedback step (S190), as shown in FIG. 6, the feedback items generated during the production work are registered (S191), the feedback reflecting subject is identified (S192), and if the subject of the feedback is design information, design Reflected in the feedback data (S193), the design information is transmitted (S194) and the production information is generated (S196) and stored in the production information DB 130 (S197), or if the subject of the feedback is production information, it is reflected in the production feedback data (S195) The production information is generated (S196) and stored in the production information DB 130 (S197).

Therefore, by constructing the ship manufacturing process for the implementation of the smart factory as described above, by checking information integrity and by identifying the subject of incompatibility, the production plan is corrected according to the changed prior information, production shop or production schedule. By changing, you can establish a follow-up production plan and adaptively perform production for each transmission line. For feedback that occurred during production work, determine whether the subject of feedback reflection is design information or production information, and reflect it in the production information DB and store it. The information provided in the design can be compared with the information generated in production to ensure consistency, and the information necessary for production can be integrated and managed in the DB, and the manufacturing process is organically connected to supply the necessary members at the right time and wait. It is possible to prevent problems of accumulation or loss of members.

The configurations shown in the embodiments and drawings described in this specification are only one of the most preferred embodiments of the present invention, and do not represent all of the technical spirit of the present invention, and various equivalents that can replace them at the time of this application It should be understood that there may be water and variations.
