To the future-oriented optimal smart factory logistics control education system that can analyze the production efficiency according to the arrangement of various types of process paths while transporting transport objects between processes by introducing AGV (Automation Guided Vehicle) It is about.

In general, a logistics system is based on a transport device using a conveyor to reduce labor costs and increase productivity, and a robot can be installed around it to work.

Learners of these logistics systems often try and make their own designs, learn the skills of those who have the skills, or learn from people with design skills, but in the actual field, they need a manpower that can be applied immediately after employment. Logistics education equipment was proposed, preferring to have basic design capabilities even when hiring new hires.

1A and 1B are diagrams showing a conventional logistics education device and a state in which the logistics education device is composed of two sets and arranged in a 'a' shape on a plane.

Specifically, in Patent No. 10-1279454 (invention name: logistics education device), the block 10, the first driving block 20, the second driving block 30, and the belt 40 as shown in Fig. 1A. ), A magnet 51, 52, 53, and a logistics control device consisting of a motor 60 are assembled into two sets, respectively, as shown in FIG. 1B, the first set part 100 and the second set part 200 The first set part 100 and the second set part 200 are arranged in a 'a' shape on a flat surface in a state configured as an object discrimination sensor 1, a first contact sensor 2, A second contact sensor (3), a first drive cylinder (4), a first feed robot (5), a second feed robot (6), a second drive cylinder (7) and a controller (8) are added, and the controller (8) is the object discrimination sensor (1) and the first and second contact sensors (2) (3) are electrically connected, the transfer member (1a) above the belt (40) of the first set part (100) ), The first set unit 100 is driven by driving the motor 60 of the first set unit 100. Transfer the transfer body (1a) disposed on the belt 40 of the upper, and when the transfer body (1a) is in contact with the first contact sensor (2), the motor (60) of the second set unit (200) To drive the transfer body 1a located above the belt 40 of the second set unit 200, and when the transfer body 1a contacts the second contact sensor 3, The first and second transfer robots 5 and 6 for stopping the driving of the motor 60 of the second set unit 200 so that learners transfer the blocks 10 and the conveying body 1a using the principle of the conveyor ) Is simply assembled without the need for a separate tool, and by allowing the learner to write a program of the controller himself, the learning ability can be improved by practicing with simple tasks from installation to operation of the automatic logistics system.

On the other hand, in the current manufacturing industry, as the number of skilled workers decreases due to the aging, it is difficult to properly respond when problems occur in the production site, and the product life cycle is shortening, and as it changes to customized mass production, a light and flexible production system is required. As the IT technology advances, the paradigm is changing to a smart factory that enables custom manufacturing that can reflect user needs, virtual manufacturing using software, and collaborative manufacturing through the interlocking of all product value chains. In addition to manufacturing powerhouses such as Germany, the United States, etc., this new paradigm is increasing production efficiency and enhancing manufacturing competitiveness through eco-friendly customized production.

This smart factory is a concept that extends from the factory automation that existed before, and integrates the entire process of product planning, design, production, distribution, etc. into information and communication technology, and integrates customized products with minimum cost time. As a future factory that produces, based on the core technologies of the Internet of Things (IoT) and cyber physical systems (CPS), all stages of manufacturing are automated and informatized, and the entire value chain is aimed at a production system that works in real time like a single factory.

In other words, data is collected and analyzed in real time through sensors installed in the facilities and machines in the factory, and all the situations in the factory can be seen at a glance, and it can be analyzed and controlled according to the purpose, unmanning production facilities and automating management. Factory automation is optimized for each unit process, so it is difficult to see that the entire process is organic, and it is possible to freely link data between processes before and after, enabling optimization from a holistic point of view. The implemented manufacturing operating environment is the basis for implementing a flexible manufacturing system suitable for multi-product complex production.

From this, the necessity of training for the smooth operation of the smart factory in the manufacturing field has increased, but there has been a problem that the device or system corresponding thereto is not sufficient.

In particular, there is a need for education that can cultivate the ability to analyze and increase production efficiency while freely deforming from a fixed process arrangement such as a conveyor that is basically applied to a logistics control system.

First, in the I-line, compared to the L-line and U-line, the moving distance of the AGV 130 is short, so that the production time is shorter, but the space for arranging each process execution module 120 is vertically long and horizontal This is only possible if the space is short.

Next, the L-line and the U-line can efficiently arrange the process in a limited space, but the moving distance of the AGV 130 is long, so that the total production time is long.

Here, when each process performing module 120 is freely disposed, for example, when a processing process takes a long time, for example, when a delay in production time occurs in a specific process, the facility is added to the process. The simulation can be interpreted as a smooth production of the entire process, which can shorten the total production time.

In addition, when additional equipment is added to the limited space as described above, the most efficient arrangement can be simulated in advance.

From this, a fixed line process, such as a conveyor, is devised as an independent module for each process of the entire production, and AGV is substituted for the conveyor to transport the transport along the process paths that are variously formed between processes. As a whole, you will be able to learn to improve productivity in the smart factory, which is a new environment for manufacturing companies, and at this time, the strength of the smart factory manufacturing environment, data-based decision-making method (data collection, analysis, and productivity improvement through informatization) Quality improvement method).
