Description

Technical Field

[0001] This invention belongs to the technical field, specifically an intelligent storage rack for automated warehouses. Background Technology

[0002] Currently, automated warehouses generally use a single-rail stacker crane and a single transfer car arranged in the middle of double-row racks to complete the entry and exit of goods. The stacker crane relies on steel wire ropes / cables to achieve the vertical lifting of the forks and the load-bearing frame. The cable needs to pass through the top guide wheel for reversing and limiting. During the long-term reciprocating winding and unwinding process, the cable continuously generates sliding friction between the cable and the guide wheel and guide seat. The most common maintenance method is manual lubrication. However, the timing of lubrication cannot match the equipment load conditions. When the cargo is being lifted, the cable is under the maximum tension and friction is the most intense, but dry friction due to lack of oil often occurs. In contrast, excessive oil is easily applied during the unloaded lowering stage, resulting in uneven lubrication. In view of this, an intelligent storage rack for automated warehouses is proposed. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given the following technical problems in the existing technology: the common maintenance method is to manually add lubricating oil periodically. The timing of lubrication cannot match the equipment load conditions. When the cargo is lifted, the cable bears the maximum tension and the friction is the most intense, but dry friction due to lack of oil often occurs. In the unloaded lowering stage, it is easy to apply too much oil, resulting in uneven lubrication.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent storage rack for automated warehouses, comprising a storage rack, guide rails, and a transfer mechanism; The guide rail includes a lower guide rail and an upper guide rail, which are arranged in parallel. The lower guide rail is located at the bottom and the upper guide rail is located at the top. The transfer mechanism includes a lower guide platform, a bracket, and an upper guide platform. The lower guide platform is slidably mounted on the lower guide rail. The bracket is used to connect the lower guide platform and the upper guide platform. The upper guide platform is slidably mounted on the upper guide rail. A guide component is provided at the edge of the upper guide platform, a first chamber is provided at the center of the guide component, and a second chamber is provided on both sides of the guide component near the first chamber. The first chamber is provided with a rotatable guide wheel, and a package box is provided at the end of the first chamber near the guide component; The second chamber is equipped with a transmission mechanism.

[0006] As a preferred technical solution for intelligent storage racks in automated warehouses, the storage rack includes a first storage rack and a second storage rack, with the guide rail positioned between the first and second storage racks.

[0007] As a preferred technical solution for intelligent storage racks in automated warehouses, the support frame is equipped with a sliding U-frame, which is used for carrying and transferring goods.

[0008] As a preferred technical solution for intelligent storage racks used in automated warehouses, a winding machine is provided on the outside of the support frame, and a guide cable is wound on the winding machine. The other end of the guide cable passes through the guide assembly and is connected to the U-frame.

[0009] As a preferred technical solution for intelligent storage racks in automated warehouses, a liquid storage box is provided at the end of the second chamber near the guide component. The liquid storage box and the package box are connected by a pipe, and the side of the liquid storage box is provided with an elastic protrusion.

[0010] As a preferred technical solution for intelligent storage racks in automated warehouses, the transmission mechanism includes a central shaft, an outer cylinder, and a transverse plate. The central shaft is rotatably disposed in a second chamber. The central shaft and the guide wheel are coaxially driven, wherein the central shaft rotates together with the guide wheel. The outer cylinder rotates unidirectionally on the inner wall of the second chamber, and the central shaft is located at the center of the outer cylinder.

[0011] As a preferred technical solution for intelligent storage racks in automated warehouses, a triangular block is fixedly arranged on the inner edge of the outer cylinder, the triangular block is triangular in shape, and a rotating rod is rotatably arranged on the outer periphery of the central shaft through a torsion spring.

[0012] As a preferred technical solution for intelligent storage racks in automated warehouses, the outer cylinder has a groove on its outer periphery, and a linkage groove is formed on the inner edge of the groove. The linkage groove has multiple uneven arc segments.

[0013] As a preferred technical solution for intelligent storage racks in automated warehouses, a transverse sliding plate is provided in the groove, and a straight rod is provided on the side of the end of the transverse sliding plate. The straight rod is located in the linkage groove and can drive the transverse sliding plate to change position.

[0014] As a preferred technical solution for intelligent storage racks in automated warehouses, a guide seat is provided along the inner edge of the second chamber, and the transverse plate passes through the guide seat to ensure horizontal movement of the transverse plate.

[0015] The beneficial effects of this invention are: When the cargo is lifted and the winding machine winds the guide cable in direction A, the guide wheel synchronously drives the central shaft to rotate in the same direction. The rotating rod engages with the short side of the triangular block on the inner side of the outer cylinder, driving the outer cylinder to rotate synchronously. The concave and convex linkage grooves on the outer circumference of the outer cylinder push the straight rod, causing the transverse plate to reciprocate and extend, intermittently squeezing the elastic protrusion on the side of the liquid storage box. The lubricating fluid in the liquid storage box is sent into the package box through a pipeline, continuously spraying and contacting the guide cable, greatly reducing dry friction between the cable and the guide wheel and guide components, improving the durability of the entire transmission component of the cable and guide wheel, and making the transport of goods smoother. When the winding machine releases the cable and lowers the goods along direction B, the central shaft rotates in the opposite direction, and the rotating rod slides along the long slope of the triangular block, preventing the outer cylinder from rotating. The transverse plate no longer presses against the liquid storage box, and the lubricant output stops. Lubrication is only supplied during the stage of maximum friction when the goods are lifted under load; no lubricant is consumed during the unloaded lowering stage, avoiding unnecessary waste of lubricant and reducing warehouse maintenance consumable costs.

A first chamber 400 is opened at the center of the guide assembly 305. Second chambers 500 are opened on both sides of the guide assembly 305 near the first chamber 400. Reference Figure 10 and Figure 11 A guide wheel 401 is rotatably provided in the first chamber 400, and a package box 402 is provided at the end of the first chamber 400 near the guide assembly 305; Reference Figure 7 , Figure 8 and Figure 11 The second chamber 500 is provided with a liquid storage box 501 at the end near the guide component 305. The liquid storage box 501 and the package box 402 are connected by a pipe. The side of the liquid storage box 501 is provided with an elastic protrusion 502. Reference Figure 8 , Figure 9 , Figure 11 and Figure 12 A transmission mechanism 600 is configured in the second chamber 500. The transmission mechanism 600 includes a central shaft 601, an outer cylinder 602, and a transverse plate 608. The central shaft 601 is rotatably disposed in the second chamber 500. The central shaft 601 and the guide wheel 401 are coaxially driven, wherein the central shaft 601 rotates together with the guide wheel 401. The outer cylinder 602 rotates unidirectionally on the inner wall of the second chamber 500, and the central shaft 601 is located at the center of the outer cylinder 602. A triangular block 603 is fixedly disposed on the inner edge of the outer cylinder 602. The triangular block 603 is triangular in shape. The outer edge of the central shaft 601... A rotating rod 604 is rotatably provided around the periphery of the outer cylinder 602 via a torsion spring; a groove 605 is provided on the outer periphery of the outer cylinder 602, and a linkage groove 606 is provided on the inner edge of the groove 605, with multiple uneven arc segments on the linkage groove 606; a transverse sliding plate 608 is provided in the groove 605, and a straight rod 607 is provided on the side of the end of the transverse sliding plate 608, which is located in the linkage groove 606 and can drive the transverse sliding plate 608 to change position; a guide seat 609 is provided on the inner edge of the second chamber 500, and the transverse sliding plate 608 passes through the guide seat 609 to ensure that the transverse sliding plate 608 moves horizontally.

[0033] In this plan Figure 9 In the diagram, A represents the winding direction of the 306 guide cable, and B represents the unwinding direction.

[0034] This implementation allows for the following: Goods are placed in the U-frame 303 and transported to the designated first or second storage rack 101 position via the lower guide 300. The winding machine 304 then winds the guide cable 306, lifting the goods. The guide cable 306 drives the guide wheel 401 to rotate, which in turn drives the central shaft 601 to rotate. At this moment, the central shaft 601 moves in the direction A. The rotating rod 604 abuts against the short side of the triangular block 603, causing the outer cylinder 602 to rotate. During rotation, the outer cylinder 602, relying on the linkage groove 606 and the straight rod 607, reciprocates to drive the transverse plate 608 to extend and retract, thereby achieving intermittent compression of the elastic protrusion 502. This allows lubricating / anti-wear fluid to be introduced into the package box 402 and guided to the guide cable 306, enabling the guide cable 306 to... When under pressure during transmission, the friction of the guide cable 306 is reduced, thereby improving its overall service life and making the overall operation smoother. After the goods are transferred to the second storage rack 101 or the first storage rack 100, the rewinder 304 controls the guide cable 306 to unwind. During the unwinding process, the guide cable 306 drives the guide wheel 401 and the central shaft 601 to move in the B direction. The long slope of the triangular block 603 can squeeze the rotating rod 604. Under the unidirectional rotation of the outer cylinder 602 and the action of the rotating rod 604 and the triangular block 603, the guide wheel 401 will not affect the outer cylinder 602 when rotating. This ensures that the lubricating / anti-wear fluid will not overflow and act on the guide cable 306 when it is unwinding, ensuring the conservation of lubricating / anti-wear fluid during the labor-saving process. At the same time, it can also ensure that after lubrication / anti-wear is performed immediately after startup, it does not need to be lubricated / anti-wear performed again very soon.
