Description

Technical Field

[0001] This invention belongs to the field of stacking equipment technology, specifically relating to an aisle-type stacker for pharmaceutical packaging boxes. Background Technology

[0002] Automated storage and retrieval systems (AS / RS) are a core component of modern logistics systems. Aisle stacker cranes, as key equipment, are primarily responsible for the automated storage and retrieval of goods within high-level racking aisles. Their performance directly determines the efficiency and reliability of the entire warehousing system. Aisle stacker cranes for pharmaceutical packaging boxes are specialized automated storage equipment designed specifically for the characteristics of pharmaceutical packaging boxes. They are primarily used in the aisles of automated storage and retrieval systems in the pharmaceutical industry. Through three-dimensional coordinated movement of walking, lifting, and extension, they achieve precise storage and retrieval of pharmaceutical packaging boxes between racks and aisles, multi-level stacking, and intelligent sorting.

[0003] Currently, traditional aisle-type stacker cranes generally adopt a structure with a single-layer fork and a lifting platform. During storage and retrieval operations, the lifting platform needs to lift and lower the forks to the height of each target storage location, performing only one "store" or "retrieve" action at a time. For items such as pharmaceutical packaging boxes, which have relatively uniform specifications but high throughput requirements, the stacker crane needs to frequently travel between the warehouse entrance and storage locations at different heights. A significant amount of time is consumed in idle operation and repeated lifting and lowering processes, making it difficult to further improve the overall throughput efficiency. Moreover, energy consumption is high, and frequent start-stop and lifting and lowering operations increase equipment energy consumption and lead to high operating costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a lane-type stacker for pharmaceutical packaging boxes.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a lane-type stacker crane for pharmaceutical packaging boxes, including a traveling steel rail, a mounting base slidably connected to the traveling steel rail, a support frame symmetrically fixedly connected to the upper end of the mounting base, multiple sets of limiting rails opened inside the support frame, and a gantry frame fixedly connected to the upper end of the support frame; a drive assembly fixedly connected to one side of the mounting base, a lifting auxiliary assembly slidably connected to the support frame, a lifting platform fixedly connected between the lifting auxiliary assemblies, a lifting drive assembly fixedly installed on the support frame, multiple sets of telescopic fork assemblies arranged sequentially from top to bottom on the lifting platform, and multiple layers of moving assemblies fixedly installed on the lifting platform.

[0006] Through the above technical solution, the setting of the drive component makes the device less prone to derailment, thereby greatly improving the overall work efficiency and saving the time of loading and unloading packaging boxes. The setting of multi-layer moving components and telescopic fork components reduces the time of back-and-forth movement, raising and lowering the device, allowing multiple packaging boxes to be placed at one time.

[0007] Furthermore, the drive assembly includes a drive fixing plate fixedly mounted to the mounting base, a drive motor fixedly mounted on the upper end of the drive fixing plate, main side traveling wheels symmetrically and rollingly arranged on both sides of the traveling rail, the main side traveling wheels being fixedly connected to the output end of the drive motor, multiple sets of auxiliary side traveling wheels symmetrically and rotatably connected on both sides of the mounting base, a support groove being provided in the mounting base, and multiple sets of mounting rollers being evenly and rotatably connected in the support groove.

[0008] Through the above technical solution, the output end of the drive motor drives the main side walking wheels on both sides to move back and forth along the walking rail, providing the main driving force. Multiple sets of auxiliary side walking wheels on both sides closely follow the sides of the walking rail to assist rolling. Together with the multiple sets of rollers installed in the support groove, the stability of the device during movement is enhanced.

[0009] Furthermore, the lifting auxiliary component includes a lifting box that is slidably connected to the support frame. A first mounting groove is provided inside the lifting box. First mounting grooves are provided on both sides of the lifting box. A first lifting wheel is rotatably connected in the first mounting groove. A second lifting wheel is rotatably connected in each of the first mounting grooves. The first and second lifting wheels are respectively disposed in the limiting track and roll in contact with the limiting track.

[0010] Through the above technical solution, the first and second lifting wheels in the lifting auxiliary component can roll along the limiting track in the support frame, thereby realizing the vertical limiting function of the telescopic fork assembly during the lifting process, thus ensuring that the telescopic fork assembly can stably and quickly reach the specified height of the shelf.

[0011] Furthermore, the lifting drive assembly includes a lifting backplate frame fixedly connected to a support frame on one side. A reduction motor is fixedly installed on the lifting backplate frame. Two drive winches are fixedly connected to the output end of the reduction motor. Two sets of tensioning wheels are symmetrically arranged above the reduction motor. The tensioning wheels are fixedly connected to the support frame. Two sets of first guide wheels are fixedly installed on one side of the upper end of the gantry frame. Two sets of third guide wheels are fixedly installed on the other side of the upper end of the gantry frame. Two sets of second guide wheels are symmetrically fixedly installed at the lower end of the lifting platform. Two sets of positioning blocks are fixedly connected to the upper end of the support frame on the other side. Steel wire ropes are respectively sleeved on the two drive winches. The two steel wire ropes are respectively wound between the corresponding two sets of tensioning wheels, first guide wheels, second guide wheels, and third guide wheels. The ends of the two steel wire ropes away from the drive winches are respectively fixed to the corresponding positioning blocks. The steel wire ropes pass through the two sets of lifting auxiliary components in sequence.

[0012] With the above technical solution, when the corresponding shelf position is reached, the reduction motor is started. The reduction motor drives the drive winches on both sides to rotate. Under the traction of the steel cable in the drive winch, the lifting platform can be moved up or down.

[0013] Furthermore, the multi-layer moving assembly includes a drive cylinder fixedly connected to the lifting platform. A drive frame is fixedly connected to the output end of the drive cylinder. A first moving frame is fixedly connected to both ends of the drive frame. A second moving frame is slidably connected inside the first moving frame. A third moving frame is slidably connected inside the second moving frame. The side of the first moving frame near the telescopic fork assembly is fixedly connected to the lower telescopic fork assembly. The side of the second moving frame near the telescopic fork assembly is fixedly connected to the telescopic fork assembly in the middle position. The side of the third moving frame near the telescopic fork assembly is fixedly connected to the upper telescopic fork assembly. Synchronous belt assemblies are respectively installed inside the first and second moving frames.

[0014] Through the above technical solution, the first, second and third moving frames of the multi-layer moving assembly can be raised synchronously under the drive of the driving cylinder. This allows the distance between the telescopic fork assemblies to be adjusted according to the different heights between the loading openings of the shelf, so that the device can place multiple goods at the same time.

[0015] Furthermore, the synchronous belt assembly includes synchronous pulleys rotatably connected to the first and second movable frames. A conveyor belt is sleeved between the synchronous pulleys on both sides. A set of synchronous belt assemblies is respectively arranged at the front and rear positions on both sides of the first and second movable frames. A first fixing block is fixedly connected inside the lifting platform. The first fixing block is fixedly connected to the conveyor belt installed on the first movable frame. A second fixing block is fixedly connected to the other end of the conveyor belt on the first movable frame away from the first fixing block. The second fixing block is fixedly installed on the outside of the second movable frame. A third fixing block is fixedly installed on one side of the synchronous pulley on the second movable frame. The third fixing block is fixedly connected to the first movable frame. A fourth fixing block is fixedly connected to the other end of the synchronous pulley on the second movable frame away from the third fixing block. The fourth fixing block is fixedly connected to the third movable frame.

[0016] Through the above technical solution, the output end of the drive cylinder pushes the drive frame, the drive frame moves upward and lifts the first moving frame. At the same time as the first moving frame moves upward, the first fixed block fixes the position of the synchronous wheel inside the first moving frame, so that the side of the synchronous wheel close to the first fixed block moves downward. Furthermore, the other side of the synchronous wheel drives the second fixed block fixedly connected to the second moving frame to move upward, so that the second moving frame moves upward. Similarly, when the second moving frame rises, the end of the synchronous wheel inside the second moving frame close to the third moving frame drives the third moving frame to move upward.

[0017] Furthermore, the telescopic fork assembly includes a mounting base, with two symmetrically arranged mounting bases each rotatably connected to a first synchronous belt group. A mounting motor is located on one side of each mounting base, and a drive shaft is fixedly connected to the output end of the mounting motor. The drive shaft is fixedly connected to the drive pulley inside one end of the first synchronous belt group. A fixed rack is engaged with the upper end of the first synchronous belt group, and a second telescopic frame is fixedly connected to the upper end of the fixed rack. A sliding frame is fixedly connected to the lower end of the second telescopic frame. Fixed guide rails are symmetrically fixed to both ends of the mounting base, and the sliding frame is slidably connected to the fixed guide rails. First side racks are symmetrically fixed to both sides of the mounting base, and second synchronous belt groups are symmetrically arranged on both sides of the second telescopic frame. The first side racks engage with the second synchronous belt groups. A third telescopic frame is slidably connected to the upper end of the second telescopic frame, and second side racks are symmetrically fixed to both sides of the inner wall of the third telescopic frame. The second side racks engage with the other side of the second synchronous belt group. A packaging box is placed on top of the telescopic fork assembly.

[0018] With the above technical solution, when the device rises to the designated position, the motor starts and drives the drive shaft to rotate. When the drive shaft rotates, it can simultaneously drive the two sets of first synchronous belts to rotate synchronously. When the two sets of first synchronous belts rotate, they can drive the fixed rack to move due to the meshing action. At the same time, the fixed guide rail can limit the movement of the second telescopic frame through the cooperation between it and the sliding frame. Furthermore, when the second telescopic frame moves, the first side rack meshes with the second synchronous belt set, thereby driving the second synchronous belt set to operate. The other side of the second synchronous belt set meshes with the second side rack on the inner wall of the third telescopic frame, thereby simultaneously driving the third telescopic frame to move. This achieves the simultaneous extension or retraction of the second and third telescopic frames, which is convenient for subsequent material loading and unloading.

[0019] Furthermore, a fixed base is fixedly connected to the side of the mounting frame away from the drive assembly, and a control cabinet is fixedly installed on the upper end of the fixed base. One side of the control cabinet is fixedly connected to the support frame through a fixed back rib, and support ribs are symmetrically fixedly connected to the lower surface of the fixed base.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention designs a matching multi-layer moving component and a telescopic fork component. Under the drive of the driving cylinder, the first moving frame, the second moving frame and the third moving frame can rise synchronously. Then, the distance between the telescopic fork components can be adjusted according to the different heights between the loading and unloading openings of the shelf. This not only allows multiple boxes to be placed at one time, greatly improving the efficiency of loading and unloading boxes, but also reduces the unnecessary back-and-forth loading and unloading time and the time for the lifting platform to rise and fall. The time to complete one box loading and unloading can realize the loading and unloading of multiple boxes at the same time, greatly improving the loading efficiency. (2) By designing a drive component, the drive component drives the mounting base to move on the walking rail. The output end of the drive motor drives the main side walking wheels on both sides to move back and forth along the walking rail, providing the main driving force. Multiple sets of auxiliary side walking wheels on both sides closely follow the sides of the walking rail to assist in rolling. In addition, the combined action with multiple sets of mounting rollers in the support groove enhances the stability of the device during movement. The drive component can quickly drive the stacking device to the corresponding shelf position or loading position, reduce the lateral force of the entire stacking device, increase the grip, and thus achieve stable forward and backward movement of the drive component.

Support ribs 17 are symmetrically fixedly connected to the lower surface of the fixed base 15.

[0026] like Figures 1-6 As shown, the lifting auxiliary component 3 includes a lifting box 30 slidably connected to the support frame 12. A first mounting groove 31 is provided inside the lifting box 30, and first mounting grooves 32 are provided on both sides inside the lifting box 30. A first lifting wheel 33 is rotatably connected in the first mounting groove 31, and a second lifting wheel 34 is rotatably connected in the first mounting groove 32. The first lifting wheel 33 and the second lifting wheel 34 are respectively set in the limiting rail 13 and roll in contact with the limiting rail 13. The first lifting wheel 33 and the second lifting wheel 34 in the lifting auxiliary component 3 can roll along the limiting rail 13 in the support frame 12, thereby realizing the vertical limiting function of the telescopic fork assembly 5 during the lifting process, thereby ensuring that the telescopic fork assembly 5 can stably and quickly reach the specified height of the shelf.

[0027] like Figures 1-5As shown, the lifting drive assembly 6 includes a lifting backplate frame 60 fixedly connected to one side support frame 12. A reduction motor 61 is fixedly installed on the lifting backplate frame 60. Two drive winches 62 are fixedly connected to the output end of the reduction motor 61. Two sets of tension wheels 63 are symmetrically arranged above the reduction motor 61 and are fixedly connected to the support frame 12. Two sets of first guide wheels 64 are fixedly installed on one side of the upper end of the gantry frame 14, and two sets of third guide wheels 66 are fixedly installed on the other side of the upper end of the gantry frame 14. Two sets of second guide wheels 65 are symmetrically fixedly installed on the lower end of the lifting platform 7. Two sets of fixed guide wheels 65 are fixedly connected to the upper end of the other side support frame 12. Positioning block 67, two drive winches 62 are respectively fitted with steel wire ropes 68. The two steel wire ropes 68 are respectively wound between the corresponding two sets of tensioning wheels 63, first guide wheel 64, second guide wheel 65 and third guide wheel 66. The ends of the two steel wire ropes 68 away from the drive winches 62 are respectively fixed to the corresponding positioning block 67. The steel wire ropes 68 pass through the two sets of lifting auxiliary components 3 in sequence. When they reach the corresponding shelf position, the reduction motor 61 is started. The reduction motor 61 drives the drive winches 62 on both sides to rotate. Under the traction drive of the steel wire ropes 68 in the drive winches 62, the lifting platform 7 can be moved up or down.

[0028] like Figures 1-8 As shown, the multi-layer moving assembly 4 includes a drive cylinder 43 fixedly connected to the lifting platform 7. A drive frame 44 is fixedly connected to the output end of the drive cylinder 43. A first moving frame 40 is fixedly connected to both ends of the drive frame 44. A second moving frame 41 is slidably connected inside the first moving frame 40. A third moving frame 42 is slidably connected inside the second moving frame 41. The side of the first moving frame 40 near the telescopic fork assembly 5 is fixedly connected to the lower telescopic fork assembly 5. The side of the second moving frame 41 near the telescopic fork assembly 5 is fixedly connected to the telescopic fork assembly 5 in the middle position. The side of the third moving frame 42 near the telescopic fork assembly 5 is fixedly connected to the upper telescopic fork assembly 5. Synchronous belt assemblies 45 are respectively installed in the first moving frame 40 and the second moving frame 41. Under the drive of the drive cylinder 43, the first moving frame 40, the second moving frame 41 and the third moving frame 42 can rise synchronously. The distance between the telescopic fork assemblies 5 can be adjusted according to the different heights between the loading openings of the shelf, so that the device can place multiple goods at the same time.

[0029] like Figures 1-8As shown, the synchronous belt assembly 45 includes synchronous pulleys 46 rotatably connected to the first movable frame 40 and the second movable frame 41. A conveyor belt 47 is sleeved between the synchronous pulleys 46 on both sides. A set of synchronous belt assemblies 45 is respectively arranged at the front and rear positions on both sides of the first movable frame 40 and the second movable frame 41. A first fixing block 48 is fixedly connected inside the lifting platform 7. The first fixing block 48 is fixedly connected to the conveyor belt 47 installed on the first movable frame 40. A second fixing block 49 is fixedly connected to the other end of the conveyor belt 47 on the first movable frame 40 away from the first fixing block 48. The second fixing block 49 is fixedly installed on the outside of the second movable frame 41. A third fixing block 410 is fixedly installed on one side of the synchronous pulleys 46 on the second movable frame 41. The third fixing block 410 is fixedly connected to the first movable frame 40. A fourth fixed block 411 is fixedly connected to the end of the synchronous pulley 46 away from the third fixed block 410. The fourth fixed block 411 is fixedly connected to the third movable frame 42. The output end of the drive cylinder 43 pushes the drive frame 44, and the drive frame 44 moves upward to lift the first movable frame 40. At the same time as the first movable frame 40 moves upward, the first fixed block 48 fixes the position of the synchronous pulley 46 inside the first movable frame 40, so that the synchronous pulley 46 moves downward on the side closer to the first fixed block 48. Furthermore, the other side of the synchronous pulley 46 drives the second fixed block 49 fixedly connected to the second movable frame 41 to move upward, so that the second movable frame 41 moves upward. Similarly, when the second movable frame 41 rises, the end of the synchronous pulley 46 inside the second movable frame 41 that is closer to the third movable frame 42 drives the third movable frame 42 to move upward.

[0030] like Figures 1-12As shown, the telescopic fork assembly 5 includes a mounting base 50. Two symmetrically arranged mounting bases 50 each have a first synchronous belt group 51 rotatably connected to them. A mounting motor 53 is located on one side of each mounting base 50. A drive shaft 52 is fixedly connected to the output end of the mounting motor 53. The drive shaft 52 is fixedly connected to the drive pulley inside one end of the first synchronous belt group 51. A fixed rack 55 is meshed and driven at the upper end of the first synchronous belt group 51. A second telescopic frame 54 is fixedly connected to the upper end of the fixed rack 55. A sliding frame 56 is fixedly connected to the lower end of the second telescopic frame 54. Fixed guide rails 57 are symmetrically fixedly connected to both ends of the mounting base 50. The sliding frame 56 is slidably connected to the fixed guide rails 57. First side racks 58 are symmetrically fixedly connected to both sides of the mounting base 50. Second synchronous belt groups 59 are symmetrically arranged on both sides of the second telescopic frame 54. The first side racks 58 mesh and drive with the second synchronous belt groups 59. A third telescopic frame 510 is slidably connected to the upper end of the second telescopic frame 54. Second side racks are symmetrically fixedly connected to both sides of the inner wall of the third telescopic frame 510. The rack 511, the second side rack 511 meshes with the other side of the second synchronous belt group 59 for transmission. A packaging box is placed on top of the telescopic fork assembly 5. When it rises to the designated position, the motor 53 starts and drives the drive shaft 52 to rotate. When the drive shaft 52 rotates, it can simultaneously drive the two first synchronous belt groups 51 to rotate synchronously. When the two first synchronous belt groups 51 rotate, due to the meshing action, they can drive the fixed rack 55 to move. At the same time, the fixed guide rail 57 can limit the movement of the second telescopic frame 54 through the cooperation between it and the sliding frame 56. Furthermore, when the second telescopic frame 54 moves, due to the meshing between the first side rack 58 and the second synchronous belt group 59, it can drive the second synchronous belt group 59 to operate. The other side of the second synchronous belt group 59 meshes with the second side rack 511 on the inner wall of the third telescopic frame 510, which can simultaneously drive the third telescopic frame 510 to move. This realizes the simultaneous extension or retraction of the second telescopic frame 54 and the third telescopic frame 510, which is convenient for subsequent material loading and unloading.

[0031] The working principle of this embodiment is as follows: the drive component 2 drives the mounting base 11 to move on the walking rail 1. The output end of the drive motor 21 drives the main side walking wheels 22 on both sides to move back and forth along the walking rail 1, providing the main driving force. Multiple sets of auxiliary side walking wheels 23 on both sides closely follow the sides of the walking rail 1 to assist rolling. Together with the multiple sets of mounting rollers 25 in the support groove 24, the stability of the device during movement is enhanced. The drive component 2 can quickly drive the stacking device to the corresponding shelf position or loading position, reducing the lateral force of the entire stacking device, thereby realizing the stable forward and backward movement of the drive component 2. When multiple sets of packaging boxes need to be placed at once, the drive cylinder 43 is activated. The output end of the drive cylinder 43 pushes the drive frame 44, which moves upward and lifts the first moving frame 40. At the same time as the first moving frame 40 moves upward, the first fixed block 48 fixes the position of the synchronous wheel 46 inside the first moving frame 40, causing the synchronous wheel 46 to move downward on the side closer to the first fixed block 48. Furthermore, the other side of the synchronous wheel 46 drives the second fixed block 49 fixedly connected to the second moving frame 41 to move upward, causing the second moving frame 41 to move upward. Similarly, when the second moving frame 41 rises, the synchronous wheel 46 inside the second moving frame 41 drives the third moving frame 42 to move upward, so that the multi-layer moving assembly 4, driven by the drive cylinder 43, can raise the first moving frame 40, the second moving frame 41, and the third moving frame 42 simultaneously. This allows the distance between the telescopic fork assemblies 5 to be adjusted according to the different heights between the shelf loading openings, enabling the device to place multiple goods simultaneously.
