Technical Field

[0001] This invention relates to the field of smart logistics technology, and in particular to a composite lifting device and a cargo inbound / outbound system. Background Technology

[0002] In order to improve the efficiency of goods storage and picking, modern warehousing has vigorously promoted and developed "goods-to-person" technology, and shuttle goods-to-person technology is one of the mainstream technologies of goods-to-person.

[0003] Goods are carried in and out of the warehouse by shuttle cars and cargo elevators. In order to facilitate the movement of shuttle cars on and off the shelves during the arrangement or maintenance of the shelves, shuttle elevators (which can be maintenance elevators or layer-changing elevators) are usually arranged at the end of the shelves to carry the shuttle cars on and off the shelves.

[0004] To achieve the above functions, separate cargo elevators and shuttle elevators are required. Each cargo elevator and shuttle elevator has its own corresponding and independent drive mechanism, resulting in a large number of devices in the cargo inbound and outbound system, a complex structure, and high cost.

[0005] Therefore, there is an urgent need for a composite lifting device and a goods entry and exit system to improve the above problems. Summary of the Invention

[0006] One objective of this invention is to provide a composite lifting device in which the shuttle lifting mechanism and the cargo lifting mechanism can share a single drive mechanism.

Detailed Implementation

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0053] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the horizontal thickness of the first feature is greater than that of the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the horizontal thickness of the first feature is less than that of the second feature.

[0055] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0056] Example 1

[0057] like Figure 1 As shown, this embodiment provides a goods inbound / outbound system, which includes a three-dimensional rack and a shuttle 300. The three-dimensional rack includes multiple sets of racks 200 arranged side by side and spaced apart. Each rack 200 includes multiple storage locations 210 for temporary storage of goods. Adjacent racks 200 form aisles, and shuttle tracks 220 are provided in the aisles. The shuttle 300 can move in the shuttle tracks 220, thereby realizing the switching of the shuttle 300 to different positions in the three-dimensional rack, thereby realizing the action of picking up and placing goods to the designated storage locations 210.

[0058] In addition, the shelving 200 is vertically equipped with multiple storage locations 210. The goods inbound / outbound system of this embodiment also includes a shuttle lifting mechanism 20 and a goods lifting mechanism 30. Both the shuttle lifting mechanism 20 and the goods lifting mechanism 30 can move vertically so that the shuttle 300 or the goods lifting mechanism 30 corresponds to the storage location 210 or aisle on the corresponding level, and the shuttle 30 and the goods lifting mechanism 30 carry the goods in and out of the warehouse. At the same time, in order to facilitate the shuttle 300 to move up and down the shelving during deployment or maintenance, a maintenance lift is generally installed at the end of the shelving 200 to carry the shuttle 300 to move up and down the shelving 200.

[0059] To achieve the above functions, it is necessary to separately arrange the cargo lifting mechanism 30 and the shuttle lifting mechanism 20. The cargo lifting mechanism 30 and the shuttle lifting mechanism 20 each have their own corresponding and independent drive mechanisms, resulting in a large number of devices included in the cargo inbound and outbound system, a complex structure, and high cost.

[0060] To solve the above problems, such as Figure 1 and Figure 2 As shown, the goods inbound / outbound system includes a composite lifting device 100, which includes a frame 10, a shuttle lifting mechanism 20, a goods lifting mechanism 30, a drive mechanism 40, and a first quick-release mechanism 50. The drive mechanism 40 is mounted on the frame 10 and includes an output end 44, which can move vertically relative to the frame 10. The goods lifting mechanism 30 is connected to the output end 44. The first quick-release mechanism 50 is located between the output end 44 and the shuttle lifting mechanism 20, and can selectively lock or unlock the output end 44 and the shuttle lifting mechanism 20.

[0061] In other words, the lifting device 100 can switch between two working modes simply by setting up a drive mechanism 40:

[0062] 1) In the first working mode: When the first quick release mechanism 50 unlocks the output end 44 and the shuttle lifting mechanism 20, the drive mechanism 40 can only drive the cargo lifting mechanism 30 to move vertically relative to the frame 10. The first working mode mainly corresponds to the cargo lifting mechanism 30 picking up and placing goods on the shelf 200. In this mode, when only the cargo lifting mechanism 30 needs to be lifted, there is no need to drive the shuttle lifting mechanism 20 to do useless lifting and lowering movements, thus reducing the energy consumption of the drive mechanism 40.

[0063] 2) In the second working mode: When the first quick-release mechanism 50 locks the output end 44 and the shuttle lifting mechanism 20, the drive mechanism 40 can simultaneously drive the cargo lifting mechanism 30 and the shuttle lifting mechanism 20 to move vertically relative to the frame 10. The second working mode mainly corresponds to the need to simultaneously realize the cargo lifting mechanism 30 picking up and placing goods on the shelf 200, and the need to put the shuttle 300 on or off the shelf.

[0064] In summary, the composite lifting device 100 provided in this embodiment can adapt to different application scenarios, and the shuttle lifting mechanism 20 and the cargo lifting mechanism 30 can share a set of drive mechanism 40. The drive mechanism 40 can realize the different working modes of the shuttle lifting mechanism 20 and the cargo lifting mechanism 30. The cargo inbound and outbound system contains a small number of devices, and the cargo inbound and outbound system has a simple structure and low cost.

[0065] Combination Figures 3-5The structure of the first quick-release mechanism 50 is described below, such as... Figures 3-5 As shown, the first quick-release mechanism 50 includes a first locking member 51, a second locking member 52, and a driving member 53. The first locking member 51 is disposed at the output end 44 of the driving mechanism 40, and the second locking member 52 is disposed on the shuttle lifting mechanism 20. The driving member 53 is used to drive the first locking member 51 and the second locking member 52 to move relative to each other, so that the first locking member 51 and the second locking member 52 are locked or unlocked. Through the setting of the driving member 53, the first locking member 51 and the second locking member 52 can be quickly switched between the locked state and the unlocked state, which facilitates the rapid switching of the composite lifting device 100 in different working modes.

[0066] Specifically, such as Figure 5 As shown, the first locking member 51 includes a mounting base 511 and a snap-fit ​​plate 512. The mounting base 511 is disposed on the output end 44 of the drive mechanism 40. The snap-fit ​​plate 512 has a pivot shaft 5121 extending vertically, which is pivotally connected to the mounting base 511. A insertion groove 5122 is formed on the side of the snap-fit ​​plate 512 away from the pivot shaft 5121, extending inward from its outer edge. The drive member 53 includes a drive body 531 and an output shaft 532 that can rotate relative to it. The drive body 531 is disposed on the output end 44 of the drive mechanism 40. The output shaft 532 is coaxially fixed with the pivot shaft 5121. The drive member 53 can drive the snap-fit ​​plate 512 to rotate relative to the mounting base 511, so that the second locking member 52 is inserted into the insertion groove 5122. The locking of the first locking member 51 and the second locking member 52 can be achieved through the simple structure of the first quick-release mechanism 50. Figure 4 As shown, the driving component 53 can also drive the latching plate 512 to rotate in the opposite direction to the mounting base 511, so that the insertion slot 5122 separates from the second locking component 52, thereby unlocking the first locking component 51 and the second locking component 52. Specifically, the driving component 53 in this embodiment can be a servo motor, which can achieve precise control of the position of the latching plate 512. Of course, in other embodiments, the driving component 53 can also be a linear drive mechanism, a linear drive mechanism integrated with a linkage mechanism, etc., as long as it can realize the unlocking and locking actions of the first locking component 51 and the second locking component 52.

[0067] Furthermore, the first quick-release mechanism 50 may also include a mounting base, which is fixed to the output end 44 of the drive mechanism 40, and the drive body 531 is fixed to the mounting base, thereby achieving a stable connection between the drive body 531 and the output end 44 of the drive mechanism 40. In addition, the positions of the mounting base and the output end 44 of the drive mechanism 40 are adjustable, facilitating fine-tuning of the relative positions of the drive body 531 and the output end 44 of the drive mechanism 40. Furthermore, the mounting base may have a clearance hole through which the output shaft 532 can pass. The output shaft 532 is connected to the clearance hole via a bearing. The bearing provides stable support for the output shaft 532 and prevents wear on the output shaft 532.

[0068] like Figure 4 and Figure 5 As shown, the first quick-release mechanism 50 also includes a retainer 54, which is fixed to the output end 44 of the drive mechanism 40. The retainer 54 includes a receiving groove 541 with an opening 5411. When the second locking member 52 is inserted into the insertion groove 5122, the retaining plate 512 is engaged in the receiving groove 541. The retainer 54 cooperates with the mounting base 511 to provide stable support for the retaining plate 512, preventing the retaining plate 512 from deforming and drooping downwards. This ensures that the second locking member 52 and the insertion groove 5122 are always aligned, guaranteeing a smoother insertion action between the second locking member 52 and the insertion groove 5122. The number of retainers 54 can be one, two, or more. If at least two are provided, at least two retainers 54 are arranged horizontally, and at least two retainers 54 can provide stable support for the retaining plate 512.

[0069] In addition, the composite lifting device 100 also includes a second quick-release mechanism, which is disposed between the output end 44 and the cargo lifting mechanism 30. The second quick-release mechanism can selectively lock or unlock the output end 44 and the cargo lifting mechanism 30. When the output end 44 and the cargo lifting mechanism 30 are in the unlocked state, the drive mechanism 40 cannot drive the cargo lifting mechanism 30 to move in the vertical direction; when the output end 44 and the cargo lifting mechanism 30 are in the locked state, the drive mechanism 40 can drive the cargo lifting mechanism 30 to move in the vertical direction.

[0070] In other words, by simply setting up a drive mechanism 40, the lifting device 100 can switch between the first two working modes and the third working mode:

[0071] In the third working mode: the second quick-release mechanism unlocks the output end 44 and the cargo lifting mechanism 30, and the first quick-release mechanism 50 locks the output end 44 and the shuttle lifting mechanism 20. The drive mechanism 40 can drive only the shuttle lifting mechanism 20 to move vertically relative to the frame 10. The scenario corresponding to the third working mode is that only the shuttle 300 needs to be lifted or lowered, such as only needing to transport the shuttle 300 to a predetermined position, needing to remove the shuttle 300 to be repaired, or needing to put the repaired shuttle 300 back on to a predetermined position. In this mode, when only the shuttle 300 needs to be lifted or lowered, there is no need to drive the cargo lifting mechanism 30 to perform useless lifting and lowering movements, thus reducing the energy consumption of the drive mechanism 40.

[0072] The second quick-release mechanism can be selected from a structure similar to the first quick-release mechanism 50, which will not be described in detail in this application.

[0073] It should be noted that when the shuttle lifting mechanism 20 or the cargo lifting mechanism 30 is unlocked from the output end 44, the shuttle lifting mechanism 20 or the cargo lifting mechanism 30, which does not move vertically with the output end 44, is located at the bottom layer.

[0074] Combination Figures 3-5 The structure of the drive mechanism 40 will be described, such as Figures 3-5 As shown, the drive mechanism 40 includes a first drive wheel 411, a second drive wheel 412, a first annular drive belt 413, and a rotary drive output component 47. The first drive wheel 411 and the second drive wheel 412 are both pivotally connected to the frame 10 and are arranged at intervals in the vertical direction. The rotary drive output component 47 is used to drive the first drive wheel 411 or the second drive wheel 412 to rotate. The first annular drive belt 413 is sleeved on the outer periphery of the first drive wheel 411 and the second drive wheel 412 and is tensioned by the first drive wheel 411 and the second drive wheel 412. The output end 44 is connected to the first annular drive belt 413. The output end 44 can be selectively connected to the shuttle lifting mechanism 20 and / or the cargo lifting mechanism 30. When the rotary drive output component 47 is working, it drives the first transmission wheel 411 or the second transmission wheel 412 to rotate, thereby causing the first annular transmission belt 413 to rotate, thus realizing the movement of the output end 44 in the vertical direction, thereby realizing the movement of the shuttle lifting mechanism 20 and / or the cargo lifting mechanism 30 in the vertical direction.

[0075] like Figure 2 and Figure 3 As shown, the frame 10 includes a connecting plate 12 and two columns 11. The columns 11 extend vertically and are arranged side by side with intervals. The connecting plate 12 is connected to the top of the two columns 11. The connecting plate 12 and the two columns 11 together form a receiving space for accommodating the drive mechanism 40.

[0076] Secondly, such as Figure 4 and Figure 5 As shown, the output end 44 includes a mounting plate 441, a first guide wheel 442, and a second guide wheel 443. Both the first guide wheel 442 and the second guide wheel 443 are pivotally connected to the mounting plate 441. The first guide wheel 442 includes a second pivot shaft extending along the direction of goods entering and leaving the warehouse, and the second pivot shaft is pivotally connected to the output end 44. The first guide wheel 442 can roll along the frame 10. The second guide wheel 443 includes a third pivot shaft extending in a direction perpendicular to the direction of goods entering and leaving the warehouse, and the third pivot shaft is pivotally connected to the output end 44. The second guide wheel 443 can roll along the frame 10. The arrangement of the first guide wheel 442 and the second guide wheel 443 enables the output end 44 to move relatively smoothly relative to the frame 10 in the vertical direction, avoiding jamming problems when the output end 44 moves in the vertical direction. In addition, the specific positions of the first guide wheel 442 and the second guide wheel 443 can guide the output end 44 to move in the vertical direction, thus preventing the output end 44 from deviating from the frame 10 when it moves in the vertical direction.

[0077] Combination Figure 3 The structure of the cargo lifting mechanism 30 is described, such as... Figure 3 As shown, the cargo lifting mechanism 30 includes a mounting frame 31, a second annular transmission belt 34, a first conveyor roller 32, and a second conveyor roller 33. The mounting frame 31 can be selectively connected to the drive mechanism 40. The first and second conveyor rollers 32 and 33 are pivotally connected to the mounting frame 31 and both extend in a direction perpendicular to the cargo entry / exit direction. The first and second conveyor rollers 32 and 33 are arranged along the cargo entry / exit direction, and the first and / or second conveyor rollers 33 can rotate relative to the mounting frame 31. The second annular transmission belt 34 is sleeved on the outer periphery of the first and second conveyor rollers 32 and 33 and is tensioned by both the first and second conveyor rollers 32 and 33. When the first or second conveyor roller 33 is working, the second annular transmission belt 34 can rotate relative to the mounting frame 31, enabling the transfer of goods on the belt to the shelf 200 and the transfer of goods on the shelf 200 to the cargo lifting mechanism 30.

[0078] Combination Figure 6 The structure of the shuttle lifting mechanism 20 is described below, such as... Figure 6As shown, the shuttle lifting mechanism 20 includes a carrier platform 21 and a guide rail 22. The carrier platform 21 has a channel 211 extending along the running direction of the shuttle 300. The guide rail 22 extends along the running direction of the shuttle 300 and is disposed in the channel 211. The guide rail 22 can connect with the shuttle track 220. The shuttle 300 is disposed in the channel 211 and can move along the guide rail 22. The shuttle 300 can move along the guide rail 22 onto the shuttle track 220. In addition, the carrier platform 21 is provided with weight reduction holes, thereby achieving the lightweighting of the shuttle lifting mechanism 20.

[0079] Example 2

[0080] like Figure 7 and Figure 8 As shown, this embodiment provides a composite lifting device 100, the structure of which is basically the same as that of the composite lifting device 100 in Embodiment 1, the main difference being:

[0081] Two cargo lifting mechanisms 30 are configured, positioned on either side of the shuttle lifting mechanism 20. A single drive mechanism 40 can drive any number of the two shuttle lifting mechanisms 20 to move vertically, enabling the composite lifting device 100 to operate in different modes. When one drive mechanism 40 simultaneously drives both cargo lifting mechanisms 30 to move vertically, the efficiency of loading and unloading cargo is improved.

[0082] The cargo lifting mechanism 30 also includes a fourth transmission component 45. The first transmission component 41 can drive one cargo lifting mechanism 30 to move vertically, and the fourth transmission component 45 can drive another cargo lifting mechanism 30 to move vertically. The drive mechanism 40 can selectively drive the first transmission component 41 and / or the fourth transmission component 45 to work.

[0083] Specifically, the first transmission assembly 41 further includes a first transmission shaft 414 and a first clutch 415. The first transmission shaft 414 is pivotally connected to one side of the frame 10, and the second transmission wheel 412 is coaxially mounted on the first transmission shaft 414 with the first clutch 415. The cargo lifting mechanism 30 further includes a second transmission assembly 42, a third transmission assembly 43, and a fourth transmission assembly 45. The fourth transmission assembly 45 includes a seventh transmission wheel 451, a second transmission shaft 452, a second clutch 453, an eighth transmission wheel, and a fifth annular transmission belt. The seventh transmission wheel 451 and the eighth transmission wheel are distributed vertically and pivotally connected to another frame 10. The fifth annular transmission belt is sleeved on the outer periphery of the seventh transmission wheel 451 and the eighth transmission wheel and is tensioned by the seventh transmission wheel 451 and the eighth transmission wheel. Another cargo lifting mechanism 30 can be fixedly connected to the fifth annular transmission belt, and the seventh transmission wheel 451 and the second clutch 453 are coaxially fixed on the second transmission shaft 452. The first drive shaft 414 is connected to the output shaft of the rotary drive output component 47 via the second drive assembly 42, and the second drive shaft 452 is connected to the output shaft of the rotary drive output component 47 via the third drive assembly 43, thereby enabling the transmission of power from the rotary drive output component 47 to the first drive assembly 41 or to the fourth drive assembly 45.

[0084] like Figure 8 As shown, the second transmission assembly 42 includes a third transmission wheel 421, a fourth transmission wheel 422, and a third annular transmission belt 423. The third transmission wheel 421 is coaxially fixed to the first transmission shaft 414, and the fourth transmission wheel 422 is coaxially fixed to the output shaft of the rotary drive output component 47. The third annular transmission belt 423 surrounds the third transmission wheel 421 and the fourth transmission wheel 422 and is tensioned by both the third transmission wheel 421 and the fourth transmission wheel 422. When the output shaft of the rotary drive output component 47 rotates, the fourth transmission wheel 422 rotates, driving the third annular transmission belt 423 and the third transmission wheel 421 to rotate, thereby realizing the rotation of the first transmission shaft 414.

[0085] like Figure 8 As shown, the third transmission assembly 43 includes a fifth transmission wheel 431, a sixth transmission wheel 432, and a fourth annular transmission belt 433. The sixth transmission wheel 432 is coaxially fixed to the second transmission shaft 452, and the fifth transmission wheel 431 is coaxially fixed to the output shaft of the rotary drive output component 47. The fourth annular transmission belt 433 surrounds the fifth transmission wheel 431 and the sixth transmission wheel 432 and is tensioned by both of them. When the output shaft of the rotary drive output component 47 rotates, the fifth transmission wheel 431 rotates, driving the fourth annular transmission belt 433 and the sixth transmission wheel 432 to rotate, thereby realizing the rotation of the second transmission shaft 452.

[0086] When both the first clutch 415 and the second clutch 453 are engaged, the power output from the rotary drive output component 47 is transmitted to the second drive wheel 412 through the first drive shaft 414, and the first transmission assembly 41 can drive the cargo lifting mechanism 30 thereon to move vertically; at the same time, the power output from the rotary drive output component 47 is transmitted to the seventh drive wheel 451 through the second drive shaft 452, and the fourth transmission assembly 45 can drive the cargo lifting mechanism 30 thereon to move vertically.

[0087] When the first clutch 415 is engaged and the second clutch 453 is disengaged, the power output from the rotary drive output component 47 is transmitted to the second drive wheel 412 through the first drive shaft 414. The first transmission assembly 41 can drive the cargo lifting mechanism 30 on it to move in the vertical direction. At the same time, the power on the rotary drive output component 47 cannot be transmitted to the cargo lifting mechanism 30 corresponding to the fourth transmission assembly 45. The cargo lifting mechanism 30 corresponding to the fourth transmission assembly 45 is not coupled to the rotary drive output component 47, thus reducing the energy consumption of the rotary drive output component 47.

[0088] When the first clutch 415 is disengaged and the second clutch 453 is engaged, the power on the rotary drive output component 47 cannot be transmitted to the cargo lifting mechanism 30 corresponding to the first transmission component 41. The cargo lifting mechanism 30 corresponding to the first transmission component 41 is not coupled to the rotary drive output component 47, reducing the energy consumption of the rotary drive output component 47. The power output by the rotary drive output component 47 can be transmitted to the seventh transmission wheel 451 through the fourth transmission component 45. The fourth transmission component 45 can drive the cargo lifting mechanism 30 on it to move in the vertical direction.

[0089] Of course, in other embodiments, the cargo lifting mechanism 30 can also be set to three, four, or at least two, and any one of the cargo lifting mechanisms 30 can be selected to move in the vertical direction by a drive mechanism 40, which is also within the protection scope of this application.

[0090] Note that the foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
