    1. ② Rack
      1. Pallet Rack
      2. - Since goods are stored in pallet units, goods can be loaded when they are brought on pallets. Also, in the case of cargo that is difficult to gather on a pallet unit or manual work, it can be stored as a picking rack by attaching a shelf to the rack.

        - Pallet rack has excellent stability and economy because the optimal member is selected according to the load condition of cargo, and it is a prefabricated structure. Each part is easily disassembled and combined, so it is easy to adjust the number of units and transfer. In addition, the rack size can be selected freely by using various accessories, and it is divided into the connection type and independent type.

      1. Drive in Rack

        - The rack acts as both the storage and the aisle for the forklift, so it is reasonable for storage and unloading of heavy objects. In addition, it is a storage system suitable for the storage method of goods that are stored in a first-in, first-out and first-in, last-out manner in a pallet unit for a large amount of cargo.

        - It is a structure that supports the cargo in the form of an arm so that a forklift can enter. Aisles between the racks are not required, allowing large volumes of cargo to be stored.

    1. ③ Conveyor
      1. The conveyor is a conveying device that connects from the workplace to the rack when the stored goods are received or released. It is mainly used for transporting parts inside factories, transporting semi-completed products, transporting coal and oar in mines and ports, and transporting soil and sand from construction sites. It is also used as a moving workbench in combination with a worker.

      2. Conveyors have been established as the most basic transport and unloading equipment in the logistics industry. Since most are manufactured and installed, their types and forms are very diverse.

      3. Conveyors include non-motorized conveyors, dock boards, belt conveyors, etc.

    1. ④ Dock
      1. Mobile Dock
      2. - A mobile dock is a facility for easy access of logistics equipment (forklifts, etc.) to transportation means such as containers. By connecting the ground and the vehicle, the logistics equipment can be directly mounted on the means of transport.

        - That is, loading and unloading of cargo can be conducted more effectively. It has the advantage of being free to move its position as it is equipped with wheels.

      3. Fixed Type Dock
      4. - By installing in a fixed location, the height difference between the upper deck and the vehicle can be resolved. There are mechanical and hydraulic types of height adjustment methods.

    1. ⑤ Freight Elevator
      1. An elevator or a lift is a device that moves people or cargo vertically. The size and load of the freight elevator are determined depending on the structure of the building or the convenience of the user according to the purpose of transporting the cargo.

      2. The types of freight elevators include hydraulic, rope-type, etc.

    1. ⑧ Automatic Sorting Machine
      1. The automatic sorting machine combines the products transferred to each area in one line and checks the product information through the recognizer. It is one of the various automation systems that are indispensable in logistics centers that improve work efficiency, as a piece of equipment for detailed classification. It is used by postal centers and courier companies in Korea.

      2. The automatic sorting machine should have the ability to classify itself by inferring new data from various experiences, not just memorizing data simply.

  4. Logistics EquipmentLogistics Equipment
    1. ① Forklift
      1. The correct name is forklift truck, which means a truck with a fork as the name suggests. Forklifts have an L-shaped special iron bar (fork) that loads in front of the vehicle body in structure, and a mast that raises the load to a certain height. That is, the fork lifts, so it is called a forklift.

      2. When cargo is loaded on the fork, a force (overturning moment) to fall forward is applied with the front wheel as the center. At this time, the vehicle body must not fall forward, so weight must be attached to the rear of the car body to prevent it from falling forward.

  5. Forklift Forklift
    1. ② Lift
      1. A lift is equipment that is used to load the rolltainer, etc. into the vehicle by adjusting the height of the table. In general, table lifts are installed to match the height of the floor by pit work, and a freight elevator can also be manufactured using this.

      2. Lifts include mobile table lifts, low-top table lifts, U-type table lifts, etc.

    1. ③ Drum Lift
      1. Drum lift is the equipment used to transport the drum or to put the contents in the drum into a mixer or blender. It is used for transportation and loading.

    1. ④ Rolltainer
      1. Rolltainer is also called a roll cage or roll box pallet. Wheels are attached to the pallet, allowing it to be transported, where there is no forklift or pallet truck.

      2. The types of rolltainer include U-type, L-type, super, security, cold storage, and rolltainer container shelves.

  7. Transport RobotTransport Robot
    1. ① AGV(Automated Guided Vehicle)
      1. AGV is a robot that moves based on data by recognizing RFID or tags attached to the driving lane. It moves on a path guided by magnetic tape attached to the floor or ceiling, a QR code, or a rail like a train track. Despite the difficulty of quickly changing the path due to its predetermined path, there is an advantage of high-speed movement from its dedicated path.

      2. This is mainly used by companies that have large-scale logistics warehouses that can sufficiently install infrastructure such as magnetic tape or rails necessary for the movement of robots.

    1. ② AMR(Autonomous Mobile Robot)
      1. AMR is an autonomous mobile robot. Unlike AGV, AMR can move without setting a movement path for a robot in advance. This is because it can detect the surrounding environment by using data from the onboard camera, radar, and infrared sensor, avoiding obstacles and finding the destination by itself.

      2. Compared to AGV, AMR is suitable for workshops or small warehouses, where the robot’s working path can change frequently. Also, AMR is more suitable for airports and department stores, where it is difficult to install various infrastructures such as magnetic tape because the space is too wide.

  8. Operating SystemOperating System
    1. ① DPS(Digital Picking System)
      1. DPS is a system that notifies the area where the cargo to be shipped is stored, including the number of outgoing cargo, as a signal device called a light module is installed in the rack or storage area.

      2. When it is linked to the barcode or when picking for the specified quantity is completed, the signal is turned off to notify the control center of the picking status.

      3. This is suitable for small quantities and frequent picking of various kinds. It can reduce the delivery time and the case of mis-shipping due to incorrect picking.

    1. ② DAS(Digital Assort System)
      1. DAS is a system that picks all the products to be shipped out in a certain location and directs the type and quantity of the product by the data system and puts the correct quantity when many products are put into a box for each delivery location.

      2. The operation errors are reduced compared to manual operation, and the allocation speed and accuracy are improved.

    1. ③ DPC(Digital Picking Cart System)
      1. A computer is installed in the picking cart so that the workers can pick the correct product and quantity according to the proper picking order by guiding the worker with the type of shipment, the number of products, and the storage location for each shipment destination (consignee).

      2. This can be conducted without specifying a separate picking location, allowing flexible responses to changes in quantity.

      3. This is an efficient picking method that can reduce time by checking products ordered through a cart with DPS, and preparing for inspection and shipment simultaneously.
