Description

Rail system {RAIL SYSTEM}

The present invention relates to a rail system, and more specifically, to a rail system in which H-beams are connected in line to provide a track on which a moving object can run.

The term logistics is an abbreviation for physical distribution and is a general term for the function or activity of effectively moving products and goods from producers to consumers. Logistics generally refers to several activities such as packaging, unloading, transportation, storage and information. Typically, transporting products or goods goes through several processes such as packaging, storage, collection/loading, transportation, unloading/delivery, and storage. No matter what means of transportation is used, it is impossible to move products and goods without going through this process. Physical distribution is a comprehensive view of the entire movement.

In recent years, mass production, mass sales, and mass consumption have become the trends of the times, and the importance of logistics is gradually increasing as the need to streamline the flow of materials between them has increased. Additionally, the growth of logistics companies is remarkable.

To increase competitiveness, logistics companies are introducing unmanned automation systems to large logistics warehouses and expanding the use of robots in places where it is difficult to work with humans, thereby saving labor costs and increasing work efficiency and productivity. In automated logistics warehouses, automated equipment such as stacker cranes, shuttles, lifts, box pickers, and gantry robots are mainly used.

Gantry robots used in the logistics industry are installed to move along tracks and can pick up and transport various items. Gantry robots are suitable for work in relatively large work areas and can utilize the space near the ceiling of a building to the maximum, so they are used in various fields such as logistics warehouses and various automated factories.

For the smooth operation of a gantry robot, a rail system is needed to provide a track on which the gantry robot can travel. Generally, the rail system for running a gantry robot consists of H-beams connected in sequence.

However, in the process of constructing a rail system, it is difficult to connect two H-beams placed adjacent to each other so that their ends exactly match due to various reasons such as processing errors or assembly errors of the H-beams. A rail system in which adjacent H-beams are connected misaligned greatly reduces the running stability of the gantry robot.

Therefore, when constructing a rail system, it is very important to connect adjacent H-beams so that each end matches.
