Technical Field

[0001] The utility model relates to the field of logistics storage and transportation automation, in particular to an automatic storage-in and -out device for flat storage. Background Art

[0002] Flat warehouses are traditional warehouses that use ground storage, as opposed to automated high-rise warehouses. Because flat warehouses do not use high-level shelf systems and automated handling equipment, goods are usually placed directly on the ground or on low-level shelves, and are generally handled and stored by forklifts or manual labor. Flat warehouses have the following advantages: simple structure, relatively low construction cost, and high flexibility; they are suitable for scenarios with small storage requirements, low frequency of inbound and outbound storage, or a wide variety of goods that are difficult to automate.

[0003] At present, the traditional method of moving goods in the warehouse is to use forklifts or manual transportation by oxen.

[0055] 2. The in-and-out trolley moves from the transfer trolley to the corresponding lane, and then uses the code reader to identify the landmark QR code in the flat warehouse to confirm the placement of the cargo box. The in-and-out trolley picks up the cargo box by controlling the X-axis and Y-axis, and then exits the corresponding lane to reach the transfer platform. The in-and-out trolley places the picked-up cargo box on the roller line on the transfer platform.

[0056] 3. The transfer platform moves horizontally to the docking position with the ground receiving line, and the cargo boxes on the roller line are transported to the ground receiving line to complete the cargo unloading work.

[0057] 4. When the cargo box is transported from the ground receiving line to the destination, the transfer platform moves horizontally so that the roller line on the transfer platform docks with the ground receiving line, and the cargo box is transported from the receiving line to the roller line.

[0058] 5. Before the transfer platform is docked with the roller line or after the docking is completed and the cargo box is received, the inbound and outbound trolley needs to be driven onto the transfer platform and follow the transfer platform to the aisle location where the cargo box needs to be placed.

[0059] 6. When the transfer platform reaches the aisle where the cargo box is placed, the track is docked with the trolley track. The trolley picks up the cargo box on the roller line through the end picker it carries and drives the walking wheels to move it from the transfer platform to the corresponding aisle warehouse. Then, the barcode reader recognizes the landmark QR code in the flat warehouse to confirm the placement of the cargo box. The trolley controls the X-axis and Y-axis to place the cargo box on the corresponding pallet to complete the warehousing of the cargo box.
