Description

Technical Field

[0001] This invention relates to an automated storage and retrieval system, and more particularly to an automated storage and retrieval system for irregularly shaped structural members and a method for storing and retrieving these members. Background Technology

[0002] Automated storage and retrieval systems (AS / RS) are automated storage and retrieval devices that can store and retrieve large quantities of materials within a limited area. With industry development, a large number of products and materials require convenient access anytime, anywhere to achieve efficient production. Some companies produce long, rod-shaped components, which are manufactured according to different customer requirements. These customized components vary greatly in length. The storage and transfer of these irregularly shaped components has always been a key factor limiting enterprise capacity. Current technology involves directly stacking the manufactured components on the ground, but the number of stacks cannot be too high, and stacking also has specification restrictions: the bottom layer of components must be the longest, and the length of components stacked higher must decrease. This conventional stacking method presents difficulties in retrieving goods. When shipping, if the bottom layer of long components needs to be shipped first, manual handling and unloading are required, resulting in time-consuming and labor-intensive processes. Therefore, designing an automated storage and retrieval system suitable for components of varying lengths to significantly improve the efficiency of storing and retrieving these components has become a problem that needs to be solved on-site. Summary of the Invention

[0003] This invention provides an automated three-dimensional storage system and method for storing and retrieving irregularly shaped rods, solving the technical problem of convenient storage and retrieval of irregularly shaped long rod materials.

[0004] The present invention solves the above technical problems through the following technical solutions: An automated three-dimensional storage system with staggered rods includes a row of left columns and a row of right columns arranged at intervals. The left and right columns are arranged in a left-right correspondence and form a cuboid frame outline. A top beam connects the top of each left column to the top of the corresponding right column. A top rail is installed between the bottom surfaces of each top beam along the front-back direction. A ground rail is installed on the ground between the left and right columns along the front-back direction. A large-span, ultra-long stacker crane system is movable between the ground rail and the top rail. Horizontal cantilever supports extending to the right are arranged at intervals from bottom to top on the left columns, and horizontal cantilever supports extending to the left are arranged at intervals from bottom to top on the right columns.

[0005] The long-span stacker crane system consists of a traveling frame, a portal frame, and an intelligent controller. A lifting platform is installed on the portal frame, and a combined fork is installed on the lifting platform. Long rods are installed on the combined fork.

[0006] The underframe of the traveling vehicle is equipped with front traveling wheels, rear traveling wheels, front lower guide wheel sets, and rear lower guide wheel sets, which are clamped to the two sides of the ground rail. The top crossbeam of the portal frame is equipped with front upper guide wheel sets and rear upper guide wheel sets, which are clamped to the two sides of the overhead rail.

[0007] A method for storing and retrieving long rods in an automated three-dimensional warehouse system with irregularly shaped rods includes a rack identification sensor installed on a portal frame, and rack markings on both the right-hand and left-hand horizontal cantilever supports. The travel drive system and the control system of the combined forklift of the large-span, ultra-long stacker crane system are electrically connected to an intelligent controller. When long rods need to be stored, the intelligent controller automatically identifies the rack markings on the right-hand or left-hand horizontal cantilever supports using the rack identification sensor, and stores the long rod on the corresponding cantilever rack according to its length. When long rods need to be retrieved, the intelligent controller automatically identifies the rack markings on the right-hand or left-hand horizontal cantilever supports using the rack identification sensor, and uses the combined forklift to remove the long rod from the cantilever rack and place it on the lifting platform.

[0008] This invention solves the drawbacks of stacking long structural materials by using a combination of cantilever steel structure racks, a large-span ultra-long stacker crane system, and an intelligent warehouse management system for calculation and control, thus greatly increasing the storage capacity of long structural materials in the warehouse. By reading and calculating the length of each structural material through the intelligent warehouse management system, it enables the sequential and classified storage of different long structural materials, greatly improving the storage and retrieval efficiency of long structural materials in the automated warehouse.

Detailed Implementation

[0010] The present invention will now be described in detail with reference to the accompanying drawings: An automated three-dimensional storage system with irregularly shaped pillars includes a row of left columns 1 and a row of right columns 2 arranged at intervals. The left columns 1 and right columns 2 are arranged correspondingly to each other and form a cuboid frame outline. A top beam 3 connects the top of each left column 1 to the top of the corresponding right column 2, forming a portal frame. Multiple portal frames are arranged at intervals along the front-back direction. Between the bottom surfaces of the top beams 3 of each portal frame, along the front-back direction... A ceiling track 4 is installed. A ground track 5 is installed on the ground between the left column 1 and the right column 2, running in the front-to-back direction. A large-span, ultra-long stacker crane system 6 is installed between the ground track 5 and the ceiling track 4. The large-span, ultra-long stacker crane system 6 travels back and forth along the ground track 5. On the left column 1, horizontal cantilever supports 7 are installed at intervals from bottom to top. The corresponding horizontal cantilever supports 7 on the adjacent left columns form a support frame for long rods. On the right column 2, horizontal cantilever supports 8 are installed at intervals from bottom to top.

[0011] The large-span, ultra-long stacker crane system 6 consists of a traveling frame 11, a portal frame 12, and an intelligent controller 9. A lifting platform 13 is installed on the portal frame 12, and a combined fork 14 is installed on the lifting platform 13. Long rods 10 are installed on the combined fork 14. The combined fork 14 can pick up and put down the long rods 10 by extending and lowering. The intelligent controller 9 can control the traveling frame 11 to move along the ground rail 5 between the left and right racks in the forward and backward direction, transporting the long rods 10 to the corresponding storage location. The intelligent controller 9 can identify the storage location on the left and right racks and control the combined fork 14 to store and retrieve the long rods 10.

[0012] The underframe 11 of the traveling vehicle is equipped with a front traveling wheel 15, a rear traveling wheel 16, a front lower guide wheel assembly 17, and a rear lower guide wheel assembly 18. The front lower guide wheel assembly 17 and the rear lower guide wheel assembly 18 are clamped on the two sides of the ground rail 5. The top crossbeam of the portal frame 12 is equipped with a front upper guide wheel pair 19 and a rear upper guide wheel pair 20. The front upper guide wheel pair 19 and the rear upper guide wheel pair 20 are clamped on the two sides of the overhead rail 4 to ensure that the main structure of the large-span ultra-long stacker crane system 6 runs in a straight line in the front-to-back direction between the portal frames.

[0013] A method for storing and retrieving long rods in an automated three-dimensional warehouse system with irregular rods is disclosed. A rack identification sensor is installed on the portal frame 12 of a large-span, ultra-long stacker crane system 6. Rack markings are also provided on the right-facing horizontal cantilever support 7 and the left-facing horizontal cantilever support 8. The travel drive system and the control system of the combined forklift 14 of the large-span, ultra-long stacker crane system 6 are electrically connected to an intelligent controller 9. When a long rod 10 needs to be stored, the intelligent controller 9 automatically identifies the rack markings on the right-facing horizontal cantilever support 7 or the left-facing horizontal cantilever support 8 using the rack identification sensor, and stores the long rod 10 on the corresponding cantilever rack according to its length. When a long rod 10 needs to be retrieved, the intelligent controller 9 automatically identifies the rack markings on the right-facing horizontal cantilever support 7 or the left-facing horizontal cantilever support 8 using the rack identification sensor, and uses the combined forklift 14 to remove the long rod 10 from the cantilever rack and place it on the lifting platform 13.

[0014] The intelligent warehouse management system in the intelligent controller 9 uses internal software algorithms to assign serial numbers to the horizontal cantilever supports of each layer of the cantilever steel structure racking system, and further refines the horizontal cantilever supports between adjacent groups of steel structures. When the lifting platform 13 in the large-span ultra-long stacker crane system 6 picks up the long rod 10 through the combined forks 14, it first retrieves the length information of the long rod 10 through the material management system inside the production enterprise. After obtaining the length information, the intelligent warehouse management system calculates the location where the long rod 10 should be stored. The large-span ultra-long stacker crane system 6 places the long rod 10 on the corresponding horizontal cantilever support of the storage steel structure according to the information given by the intelligent warehouse management system. When the next long rod 10 needs to be stored, the intelligent warehouse management system can directly match the front end and rear end of the long rod 10 through calculation and store them sequentially.
