Description

Technical Field

[0001] This invention relates to the field of stacker crane technology for automated warehouses, and more specifically to a stacker crane for automated warehouses. Background Technology

[0002] A warehouse stacker crane is a type of equipment specifically designed for stacking goods in a warehouse. It can automate the storage, retrieval, and handling of goods. Depending on the usage and function, warehouse stacker cranes are divided into various types, including stationary stacker cranes, mobile stacker cranes, high-bay stacker cranes, and automated warehouse systems. Warehouse stacker cranes can significantly improve warehouse work efficiency and logistics operation accuracy, reduce human error and labor costs, and have become an indispensable piece of equipment in modern logistics management.

[0003] High-bay stacker cranes are commonly used in automated warehouses. However, existing high-bay stacker cranes have been found to have drawbacks. Each time, the crane needs to retrieve a single pallet containing items from the rack, transport it to several rows within the warehouse, and then retrieve the next pallet. When retrieving or placing multiple non-stackable pallets, the crane must make multiple trips between the rack and the destination, which is often located at the warehouse entrance. This significant travel distance severely impacts warehouse storage and retrieval efficiency. Furthermore, most existing stacker cranes use a single-station setup, performing multiple tasks with a single stacking structure, which is not highly efficient. Therefore, a new stacker crane for automated warehouses is needed to further improve efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a stacker crane for automated warehouses, which solves the problem of low efficiency by setting up a dual-station cross-working configuration, and solves the efficiency problem of transporting single items at a time by using multiple placement groups for intermediate storage.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figures 1-10The diagram shows a stacker crane for automated warehouses. The stacker crane includes a movable base 1 at the bottom, with multiple movable wheels 2 symmetrically arranged on both sides of the bottom of the movable base 1 for easy movement and stacking within the warehouse. Two first supports 4 are located at opposite ends of the top of the movable base 1. Two second supports 5 are also located at opposite ends of the top of the movable base 1. Two third supports 6 are located on the same side of the second supports 5, positioned between the two second supports 5, and symmetrically distributed about the longitudinal centerline of the movable base 1. A PLC controller is connected between the bottom of the two third supports 6 to automatically control the operation of the stacker crane. Furthermore, a placement plate 44 is provided on one side of the first supports 4. The placement plate 44 is also located in the middle of the two first supports 4. Multiple placement groups are equally spaced on the placement plate 44. The multiple placement groups are arranged vertically. Each placement group includes two symmetrically arranged support rods 45 for supporting and placing items. When the items are collected and placed, they are transferred to the placement rack in the automated warehouse. The first support 4, the second support 5, the third support 6 and the top of the placement plate 44 are connected to the top plate 3. Lifting motors 7 are set at the positions of the two third supports 6 on the top plate 3. The stacker is divided into two workstations, left and right, which are symmetrically arranged. Each workstation is equipped with a lifting mechanism for collecting or placing items. The lifting mechanism is controlled by a PLC controller for automated lifting. The lifting mechanisms of the two workstations work alternately to improve the overall efficiency of collecting or placing items, thereby improving the overall work efficiency.

[0036] Further such as Figure 1 and Figures 4-7 As shown, the above-mentioned lifting mechanism includes a horizontally movable base 20 installed on one side inside the second bracket 5 and the third bracket 6. The horizontally movable base 20 is provided with a second connecting block 22 and a first connecting block 21 corresponding to the positions of the second bracket 5 and the third bracket 6. The second connecting block 22 is slidably disposed in a groove opened on the inner side of the second bracket 5, and the first connecting block 21 is slidably disposed in a groove opened on the inner side of the third bracket 6. A lifting screw 18 is rotatably disposed in the groove opened on the inner side of the third bracket 6. A rotating guide rod 19 is disposed in the groove opened on the inner side of the second bracket 5. Furthermore, the lifting screw 18 passes through the top plate 3 and is connected to the output rod of the lifting motor 7. The first connecting block 21 is threadedly connected to the lifting screw 18, and the second connecting block 22 is slidably sleeved with the guide rod 19. The lifting motor 7 can drive the horizontally movable base 20 to move flexibly in the vertical direction.

[0037] Further details are as follows Figure 6 and Figure 7As shown, a horizontal moving motor is fixed to the outer end of each of the two horizontal moving bases 20. A sliding groove is provided inside the horizontal moving base 20, and a horizontal screw 23 is rotatably installed in the sliding groove. A first push plate 24 is threaded onto the horizontal screw 23. The rotation of the horizontal moving motor drives the first push plate 24 to move horizontally. When it moves to the inner limit position, it is exactly between the two support rods 45. A first telescopic structure is symmetrically arranged on both sides of the first push plate 24. A second push plate 28 is provided on the top surface of the first push plate 24. The second push plate 28 and the two first telescopic structures are connected to each other. A telescopic structure is connected, and the first telescopic structure extends and retracts on the first push plate 24. The second push plate 28 is further provided with second telescopic structures on both sides of its top. A third push plate 31 is provided on the top surface of the second push plate 28. The third push plate 31 is connected to the two second telescopic structures. The two second telescopic structures move on the second push plate 28. Through the cooperation of the first telescopic structure and the second telescopic structure, the first push plate 24, the second push plate 28 and the third push plate 31 can extend outward to collect or place items.

[0038] Furthermore, the first telescopic structure includes two symmetrically opened first motion slots on the top surface of the first push plate 24. Two first screws 26 are rotatably disposed in the two first motion slots. Two first motors 27 are correspondingly disposed on the side of the first push plate 24 near the horizontal moving base 20. The output rods of the two first motors 27 are connected to the corresponding first screws 26, driving them to move. Two sliders 42 are symmetrically disposed at the bottom of the second push plate 28 near the first push plate 24. Both sliders 42 are slidably disposed in the first motion slots and threadedly connected to the corresponding first screws 26, realizing the movement of the second push plate 28. Similarly, the second telescopic structure includes a second movement groove symmetrically opened on the top surface of the second push plate 28. A second screw 29 is rotatably arranged in the two second movement grooves. Two second motors 30 are correspondingly arranged on the side of the third push plate 31 near the second push plate 28. The output rods of the two second motors 30 are connected to the corresponding second screws 29. Two sliders 43 are symmetrically arranged at the bottom of the side of the third push plate 31 near the second push plate 28. Both sliders 43 are slidably arranged in the second movement grooves and are threadedly connected to the corresponding second screws 29 to realize the telescopic movement of the third push plate 31.

[0039] In operation, the stacker crane is moved to the working position by the PLC controller, and the first motor 27 and the second motor 30 on both sides are started simultaneously to extend the second push plate 28 and the third push plate 31 until the third push plate 31 is positioned to the outside, collecting the items to be stacked in the automated warehouse. After collection, the PLC controller controls the first motor 27 and the second motor 30 to reverse, retracting the second push plate 28 and the third push plate 31. Then, the lifting motor 7 is started, driving the lifting mechanism and the items on it to move vertically. When the lifting mechanism is level with the placement position, the horizontal movement motor is started, driving the first push plate 24 to move between the two support rods 45. The lifting mechanism lowers slightly, placing the items on the two support rods 45. The PLC controller controls the lifting mechanisms on both sides to synchronously shift and rotate. Once the placement plate 44 is full, the PLC controller controls the stacker crane to move to the placement rack in the automated warehouse. Simultaneously, two lifting motors 7 are started, moving the lifting mechanism to the corresponding horizontal height. The horizontal movement motor is then started, driving the first push plate 24 to move between the two support rods 45. The lifting mechanism rises, lifting the items, and then returns to its original position. The lifting motor 7 drives the lifting mechanism to descend until it moves to the corresponding position on the placement rack. The first motor 27 and the second motor 30 on both sides are started, extending the second push plate 28 and the third push plate 31 until the third push plate 31 carries the items onto the placement rack. The lifting mechanism lowers slightly, placing the items on the placement rack. The first motor 27 and the second motor 30 reverse, retracting the second push plate 28 and the third push plate 31, and proceeding with the transfer of the next item.

[0040] Example 2

[0041] like Figures 6-8 As shown, it is basically the same as in Embodiment 1, except that the third push plate 31 is symmetrically provided with two mounting grooves, and the limiting plate 32 is slidably installed in the two mounting grooves. Multiple first springs 33 are provided between the limiting plate 32 and the bottom of the mounting groove. The head of the limiting plate 32 is a guide slope with the guide slope tilted outward.

[0042] When collecting items, the supporting area of ​​the third push plate 31 is expanded by the limiting plates 32 on both sides, and the pallet of the items is locked in place to maintain the stability of the support.

[0043] Example 3

[0044] like Figures 1-3 and Figures 9-10As shown, it is basically the same as Embodiment 2, except that multiple support mechanisms are vertically and equally spaced between the first support 4 and the placement plate 44 of the two workstations. The multiple support mechanisms are arranged vertically and equally spaced, dividing the vertical space into multiple work areas. Each work area corresponds to the placement area of ​​the automated warehouse rack. The support mechanism includes support grooves 8 symmetrically opened on the opposite side of the first support 4 and the placement plate 44. Adjusting screws 9 are rotatably installed in the two support grooves 8. The top of the adjusting screws 9 is connected to a connecting gear 10, and the bottom of the adjusting screws 9 is threadedly connected to a movable seat 11. The movable seat 11 has an upper mounting part and a lower mounting part, and the two sides are opposite to each other. A first connecting rod 12 is rotatably connected between the upper mounting parts and the first connecting rod 12 and the upper mounting parts to prevent rotation. An end face gear 13 is fixedly connected to one end of the first connecting rod 12 near the upper mounting part. The end face gear 13 has end face teeth at the position corresponding to the connecting gear 10 and meshes with the connecting gear 10. Furthermore, a moving gear 15 is connected in the middle of the first connecting rod 12. First support rollers 14 are symmetrically sleeved on both sides of the moving gear 15. The two first support rollers 14 are movably sleeved on the first connecting rod 12. The two corresponding lower mounting parts are rotatably connected to a second connecting rod 16, and a second support roller 17 is rotatably sleeved in the middle of the second connecting rod 16.

[0045] Furthermore, in order to cooperate with the support mechanism, a second mounting groove is provided in the middle of the bottom surface of the second push plate 28. A rack plate 34 is slidably arranged in the second mounting groove. The bottom surface of the rack plate 34 is provided with teeth, which mesh with the tooth groove of the moving gear 15. A plurality of second springs 35 are connected between the rack plate 34 and the second mounting groove.

[0046] Furthermore, a mounting groove three is horizontally opened at the bottom of the first push plate 24, and a support plate 36 is slidably arranged in the mounting groove three. A through groove 38 is opened at the tail of the support plate 36. A push block 41 is set in the middle of the bottom surface of the second push plate 28 near the first push plate 24. A sliding groove 25 is opened in the middle of the first push plate 24. The push block 41 passes through the sliding groove 25 and cooperates in the through groove 38 to push the support plate 36. A mating groove 37 is opened in the middle of the top surface of the first push plate 24 to cooperate with the protruding rack plate 34 to avoid interference movement. The length of the through groove 38 is greater than that of the push block 41, so as to achieve the effect of delayed pushback and further extend the support time. A mounting groove four is opened below the head of the support plate 36. A pressure plate 39 is slidably arranged in the mounting groove four. Multiple third springs 40 are set between the pressure plate 39 and the mounting groove four. Furthermore, guide surfaces are set at both ends of the rack plate 34 and the pressure plate 39 to facilitate support and guidance.

[0047] The initial positions of the first support roller 14 and the second support roller 17 are horizontal with the bottom surface of the second push plate 28 and the bottom surface of the pressure plate 39.

[0048] When the second push plate 28 extends outward, it reaches the head of the upper mounting part and contacts the first support roller 14, sliding relative to it. The first support roller 14 rolls. Due to the damper, the first connecting rod 12 does not rotate during the sliding process. When it moves to the middle, the rack plate 34 meshes with the moving gear 15, causing the first connecting rod 12 to rotate against the damping. The rotation of the first connecting rod 12 causes the end face gear 13 to rotate, which in turn causes the connecting gear 10 to rotate. The connecting gear 10 then causes the adjusting screw 9 to rotate, which in turn causes the moving seat 11 to move downward. The moving seat 11 then causes the first connecting rod 12 to rotate. The second link 16 moves down, creating a gap with the bottom surface of the second push plate 28 to avoid interference with the slight descent of the lifting mechanism. Due to the elastic extension and retraction of the rack plate 34, the rack plate 34 remains engaged with the moving gear 15 during the downward movement of the first link 12. As the second push plate 28 extends towards the center, the push block 41 simultaneously pushes the support plate 36 out. When the rack plate 34 engages with the moving gear 15 at the center, the pressure plate 39 just contacts the second support roller 17. As the first link 12 and the second link 16 continue to extend downward, the pressure plate 39 continues to contact the second support roller 17 due to its elasticity.

[0049] When the second push plate 28 retracts inward, the rack plate 34 drives the moving gear 15 to rotate in the opposite direction. The moving gear 15 drives the first connecting rod 12 to rotate in the opposite direction. The first connecting rod 12 drives the end face gear plate 13 to rotate. The end face gear plate 13 drives the connecting gear 10 to rotate. The connecting gear 10 drives the adjusting screw 9 to rotate. The adjusting screw 9 drives the moving seat 11 to move upward. The moving seat 11 drives the first connecting rod 12 and the second connecting rod 16 to move upward, supporting the second push plate 28 and the support plate 36, and further supporting the first push plate 24. This prevents the torque on the supported items from being concentrated at the connection between the first push plate 24 and the horizontal moving base 20, and on the slider 42 connecting the second push plate 28 and the first push plate 24. The support of the first support roller 14 and the second support roller 17 further improves the service life of the lifting mechanism and ensures the stability during the stacking process.
