Description

Technical Field

[0001] This utility model relates to the field of cargo lifting technology, and in particular to a shuttle system. Background Technology

[0002] With technological advancements, automated storage and retrieval systems (AS / RS) have become increasingly widespread, and their continuous optimization has significantly promoted the development of modern logistics. An AS / RS includes a shuttle system, which in turn includes a cargo elevator. The cargo elevator is typically located on one side of the aisle, and containers enter and exit the warehouse via it. The cargo elevator's loading platform carries the containers, and the elevator is generally driven up and down by a synchronous belt mechanism. After prolonged use, synchronous belts are prone to wear and tear, and may even break. A broken synchronous belt causes the loading platform to plummet rapidly, posing a significant safety hazard and increasing the risk of accidents. Utility Model Content

[0032] 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 present 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, not the entire structure.

[0033] In the description of this utility model, 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 utility model based on the specific circumstances.

[0034] 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 first feature is at a higher horizontal level than 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 first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] This utility model discloses a shuttle system, such as Figure 1 and Figure 2As shown, the shuttle system includes a rack 50, rack rails 40, anti-fall rails 30, a cargo elevator 20, an anti-fall device 10, and a shuttle 70. The rack 50 has a storage layer with multiple storage positions and a temporary storage position 51. In a first direction, the temporary storage position 51 is located at the end of the storage layer; that is, the rack 50 includes a temporary storage position 51 located at the end in the first direction. The rack rails 40 are located between two adjacent racks 50 and extend along the first direction. The shuttle 70 is mounted on the rack rails 40, which guide the movement of the shuttle 70 between the two racks 50. The shuttle 70 can reciprocate between the storage positions and the temporary storage position 51, transporting goods to or from either position. The anti-fall rails 30 are fixed vertically. The cargo elevator 20 and the shelf 50 are arranged side by side in the first direction, with the cargo elevator 20 located on the side closest to the temporary storage position 51. The cargo elevator 20 includes a column 21 and a loading platform 22. The loading platform 22 is vertically mounted on the column 21 and can be moved to a docking position with the temporary storage position 51, allowing the loading platform 22 to retrieve and place goods from the temporary storage position 51. A fall arrestor 10 is provided on the loading platform 22 and has a first state of gripping the fall arrestor rail 30 and a second state of releasing the fall arrestor rail 30.

[0037] When the anti-fall device 10 is in the first state, because the anti-fall device 10 grips the anti-fall guide rail 30 and the anti-fall guide rail 30 is fixedly installed, the position of the loading platform 22 relative to the shelf 50 is fixed, thus achieving the purpose of preventing the loading platform 22 from falling. When the anti-fall device 10 is in the second state, the anti-fall device 10 releases the anti-fall guide rail 30, so that the setting of the anti-fall device 10 will not affect the normal lifting and lowering of the loading platform 22, nor will it add extra resistance to the normal operation of the loading platform 22, which is conducive to ensuring the smooth and efficient lifting and lowering of the loading platform 22.

[0038] Since the anti-fall device 10 is installed on the loading platform 22 and can move up and down with the loading platform 22, when the loading platform 22 needs to stop falling, the anti-fall device 10 switches to the first state to achieve anti-fall; when the loading platform 22 does not need to stop falling, the anti-fall device 10 switches to the second state, which will not generate resistance to the movement of the loading platform 22 along the anti-fall guide rail 30, so that the loading platform 22 can move smoothly along the anti-fall guide rail 30, reducing the power requirements of the drive mechanism that drives the lifting and lowering of the loading platform 22.

[0039] Compared to existing shuttle systems that do not have a fall prevention function, the shuttle system provided by this utility model has a fall prevention device 10. The fall prevention device 10 can switch to the first state of holding the fall prevention guide rail 30, which enables the shuttle system to have the function of preventing the cargo platform 22 from falling. The cargo platform 22 will not fall suddenly due to drive failure, which improves the safety of the cargo platform 22 during the lifting process and reduces the probability of safety accidents.

[0040] Continue to refer to Figure 1 As shown, the shuttle system also includes a layer-changing elevator 60, which is arranged side-by-side with the shelf rails 40 in a first direction. Specifically, each shelf rail 40 includes guide rail members 41 spaced apart in a third direction. Each guide rail member 41 includes a docking section 411 that protrudes into a temporary storage position 51 and can dock with the layer-changing elevator 60. This arrangement allows the shuttle 70 to run to the layer-changing elevator 60, using the layer-changing elevator 60 to switch between different storage layers of the shelf 50.

[0041] Optionally, the shelf 50 has multiple storage layers spaced vertically, and the temporary storage positions 51 on the multiple storage layers are located at the same end of the shelf 50. Each storage layer of the shelf 50 is provided with a corresponding shelf rail 40, and the multiple shelf rails 40 are spaced vertically. Optionally, the vertically arranged anti-fall guide rail 30 is fixed to the multiple shelf rails 40, and the anti-fall guide rail 30 is connected to the docking section 411. The fixing method includes, but is not limited to, welding or connector connection. Of course, in other embodiments, the anti-fall guide rail 30 can also be fixed to other structures and is not limited to the shelf rails 40.

[0042] Optionally, the anti-fall guide rail 30 is a T-shaped guide rail. In some embodiments, the anti-fall guide rail 30 can guide the vertical movement of the loading platform 22.

[0043] It should be noted that the cargo elevator 20 also includes a drive mechanism (not shown in the figure) for driving the lifting of the loading platform 22. Optionally, the drive mechanism is a synchronous belt mechanism. The specific structure of the synchronous belt mechanism and its connection relationship with the loading platform 22 are existing technologies and will not be described in detail here.

[0044] In this embodiment, the shuttle system also includes a control mechanism, which can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control all the electrical control components of the cargo elevator 20, the anti-fall device 10, the shuttle 70, and the floor-changing elevator 60 to perform their respective functions.

[0045] The anti-fall device 10 is installed on the cargo platform 22 of the shuttle system and works in conjunction with the anti-fall guide rail 30 to prevent the cargo platform 22 from falling in a timely manner when the drive mechanism that drives the lifting and lowering of the cargo platform 22 malfunctions, thus giving the shuttle system an anti-fall function.

[0046] Specifically, such as Figures 3 to 9 As shown, the fall arrestor 10 includes a mounting base 100 for fixing to the loading platform 22. By installing the mounting base 100 on the loading platform 22, the entire fall arrestor 10 can be installed on the loading platform 22.

[0047] The fall arrestor 10 also includes a gripper mechanism 200, which is mounted on the fixed base 100. Specifically, the gripper mechanism 200 includes a guide mechanism and two gripper members 201, forming a clamping space 2001 between the two gripper members 201. The fall arrestor guide rail 30 passes through the clamping space 2001, and at least one gripper member 201 is movably mounted on the guide mechanism, making the width of the clamping space 2001 adjustable.

[0048] The fall arrestor 10 also includes a triggering mechanism 300, which is mounted on the fixed base 100. Each triggering mechanism 300 includes a trigger plate 301 that can move along a second direction. The trigger plate 301 can drive the gripper 201 to move along the guide mechanism from a first position to a second position. The gripper 201 in the second position can grip the fall arrestor rail 30, while the gripper 201 in the first position can release the fall arrestor rail 30. The second direction is as follows: Figure 3 As shown, in one embodiment, the second direction is the vertical direction.

[0049] It should be noted that one of the two gripper pieces 201 can be fixed on the fixed base 100, and the other can be movably disposed on the guide mechanism. Under the drive of the trigger plate 301, the movable gripper piece 201 is driven to move closer to or away from the fixed gripper piece 201, thereby changing the width of the clamping space 2001. Alternatively, both gripper pieces 201 can be movably disposed on the guide mechanism. Under the drive of the trigger plate 301, the two gripper pieces 201 move closer to or away from each other, thereby changing the width of the clamping space 2001.

[0050] The anti-fall device 10 is installed on the loading platform 22 and can move up and down with the loading platform 22. When the loading platform 22 needs to be stopped from falling, the trigger plate 301 can move in the second direction and drive the gripper 201 to move along the guide mechanism to reduce the width of the clamping space 2001, so that the two grippers 201 can hold the anti-fall guide rail 30 tightly, thereby achieving anti-fall. When the loading platform 22 does not need to be stopped from falling, the gripper 201 remains in the first position and does not contact the anti-fall guide rail 30, so it will not generate frictional resistance to the loading platform 22. The anti-fall device 10 is not only low in cost and reusable, but also does not generate resistance to the movement of the loading platform 22 along the anti-fall guide rail 30 when the loading platform 22 does not need to be stopped from falling, so that the loading platform 22 can move smoothly along the anti-fall guide rail 30, reducing the power requirements of the drive mechanism that drives the lifting and lowering of the loading platform 22.

[0051] Continue to refer to Figure 3 As shown, the fixed base 100 includes a first side plate 101 and a second side plate 102, which are vertically connected. A gripper mechanism 200 is mounted on the first side plate 101, and a triggering mechanism 300 is mounted on the first side plate 101 and the second side plate 102. The second side plate 102 is mounted on the side of the loading platform 22. The installation methods include, but are not limited to, connecting with connectors, welding, etc.

[0052] Optionally, the mounting base 100 further includes a top plate 103 and a bottom plate 104. The top plate 103 is connected to the top of the first side plate 101 and the second side plate 102, and the bottom plate 104 is connected to the bottom of the first side plate 101 and the second side plate 102. The arrangement of the top plate 103 and the bottom plate 104 can enhance the structural strength of the mounting base 100. Further optionally, both the top plate 103 and the bottom plate 104 are triangular plates.

[0053] Continue to refer to Figure 4 and Figure 5 As shown, the guiding mechanism includes a guide seat 202, which guides the gripper members 201. Specifically, the guide seat 202 is fixed on the fixed base 100, and a guide groove 2021 is provided through the guide seat 202 along the second direction. Both gripper members 201 are disposed in the guide groove 2021. At least one side wall of the guide groove 2021 forms a first guide slope 2022, and at least one gripper member 201 is provided with a second guide slope 2011, which slides against the first guide slope 2022.

[0054] When only one gripper 201 moves, the guide groove 2021 has only one side wall forming a first guide slope 2022, and the moving gripper 201 is provided with a second guide slope 2011. The fixed gripper 201 is fixed at the other side wall of the guide groove 2021. When both grippers 201 can move, the two inner side walls of the guide groove 2021 both form the first guide slope 2022. The guide groove 2021 is a flared opening that is narrow at the top and wide at the bottom. Both grippers 201 are provided with a second guide slope 2011.

[0055] Continue to refer to Figure 5 As shown, when both gripper parts 201 are movable, the guide seat 202 includes a connecting part 2024 and two guide parts 2023. The connecting part 2024 is used to connect the two guide parts 2023. A guide groove 2021 is formed between the connecting part 2024 and the guide parts 2023. The inner side wall of each guide part 2023 forms a first guide slope 2022. The gripper part 201 has a wedge-shaped structure. One side wall of the gripper part 201 forms a second guide slope 2011. The second guide slopes 2011 of the two gripper parts 201 abut against the first guide slopes 2022 of the two guide parts 2023 in a one-to-one correspondence.

[0056] Continue to refer to Figure 6 As shown, the side wall surface of the gripper 201 opposite to the second guide inclined surface 2011 is the clamping surface 2012, and a clamping space 2001 is formed between the two clamping surfaces 2012. Optionally, the clamping surface 2012 is provided with an anti-slip structure, which can be an anti-slip pattern, an anti-slip pad, etc.

[0057] Continue to refer to Figure 3 and Figure 4 As shown, the guiding mechanism includes a gripper plate 203, which covers the gripper component 201. One of the gripper plate 203 and the gripper component 201 has a limiting groove 2013, and the other has a limiting pin 204, which passes through the limiting groove 2013. The number of gripper plates 203 can be one or two, and each gripper plate 203 corresponds one-to-one with a movable gripper component 201.

[0058] It should be noted that the gripper plate 203 and the guide seat 202 can exist simultaneously or independently. When the gripper plate 203 and the guide seat 202 exist simultaneously, the gripper plate 203 is fixed to the guide portion 2023 of the guide seat 202, and the width of the gripper plate 203 is greater than the width of the guide portion 2023, so that an installation space for the limiting gripper 201 can be formed between the gripper plate 203 and the connecting portion 2024. When the gripper plate 203 exists independently, the gripper plate 203 is fixed to the fixing seat 100, specifically fixed to the first side plate 101.

[0059] Optionally, the limiting groove 2013 is an oblong groove, and the number of limiting pins 204 is at least two. The straight line where the multiple limiting pins 204 are located is parallel to the extension direction of the limiting groove 2013, and the angle between this direction and the second direction is an acute angle.

[0060] Continue to refer to Figure 5 As shown, the gripper mechanism 200 also includes an upper cover plate 205, which is connected to the top of the guide seat 202. The upper cover plate 205 partially blocks the top opening of the guide groove 2021, and the upper cover plate 205 is also provided with a clearance groove for the fall arrestor rail 30. Optionally, the upper cover plate 205 is generally U-shaped, and the two protruding parts of the upper cover plate 205 are respectively fixed to the top of the two guide parts 2023.

[0061] Optionally, each protrusion of the upper cover plate 205 is further provided with a second threaded hole 2051, which is connected to the guide groove 2021. The second threaded hole 2051 is used for the ejector stud (not shown in the figure) to pass through. After the gripper 201 grips the anti-fall guide rail 30, the gripper 201 can be pushed downward by rotating the ejector stud through the second threaded hole 2051, so that the two grippers 201 release the anti-fall guide rail 30, which facilitates later maintenance.

[0062] Continue to refer to Figure 3 and Figure 4 As shown, the gripper mechanism 200 also includes a fine-tuning bolt 206. The gripper 201 has a first threaded hole 2014. One end of the fine-tuning bolt 206 is threaded into the first threaded hole 2014, and the other end abuts against the trigger plate 301. By turning the fine-tuning bolt 206, the length of the portion of the fine-tuning bolt 206 exposed outside the first threaded hole 2014 can be changed. Since the initial position of the trigger plate 301 remains unchanged, the initial position of the gripper 201 can be adjusted by changing the length of the portion of the fine-tuning bolt 206 exposed outside the first threaded hole 2014.

[0063] The number of fine-tuning bolts 206 is not less than the number of movable gripper pieces 201. When both gripper pieces 201 are movable, such as Figure 6 As shown, each gripper 201 is provided with a first threaded hole 2014, and two fine-tuning bolts 206 are respectively threaded into the two first threaded holes 2014.

[0064] Optionally, the trigger plate 301 includes two trigger parts, each corresponding to one of the two gripper pieces 201. Specifically, the two trigger parts are respectively connected to the two gripper pieces 201 via two fine-tuning bolts 206.

[0065] To limit the trigger plate 301 to its initial position during non-fall-stopping moments, thereby maintaining the gripper 201 in the first position and preventing the loading platform 22 from failing to rise and fall normally due to the gripper 201 accidentally gripping the anti-fall guide rail 30, and to ensure that the trigger plate 301 can automatically move to the second position when fall-stopping is required, refer to... Figure 3 As shown, the trigger mechanism 300 also includes a limiting structure and a first elastic member 302. The limiting structure has a limiting state and an unlocked state. In the limiting state, the limiting structure limits the trigger plate 301 to the third position (i.e., the initial position of the trigger plate 301), thereby limiting the gripper 201 to the first position. In the unlocked state, the limiting structure releases the limiting of the trigger plate 301. The first elastic member 302 has a tendency to move the trigger plate 301 from the third position to the fourth position. Under the drive of the first elastic member 302, the trigger plate 301 pushes the gripper 201 to the second position. That is, the first elastic member 302 can provide elastic force to the trigger plate 301, thereby making the gripper 201 have a tendency to move towards the second position.

[0066] Optionally, the first elastic element 302 is a helical spring.

[0067] In order to install the first elastic element 302, the triggering mechanism 300 also includes a support base 303, which is fixed on the fixed base 100 and spaced apart from the guide mechanism in the second direction. One end of the first elastic element 302 elastically abuts against the support base 303, and the other end elastically abuts against the trigger plate 301.

[0068] Optionally, the support 303 is a frame structure formed by splicing plates.

[0069] To improve the movement accuracy of the trigger board 301, continue to refer to... Figure 3 As shown, the triggering mechanism 300 also includes a guide post 304 and a bushing 305. The support base 303 has mounting holes, and the bushing 305 is disposed within the mounting holes. One end of the guide post 304 is connected to the trigger plate 301, and the other end passes through the bushing 305. The cooperation of the guide post 304 and the bushing 305 guides the movement of the trigger plate 301 in the second direction, thereby achieving high-precision movement of the trigger plate 301.

[0070] Optionally, bushing 305 is an oil-free bushing.

[0071] Optionally, there are two guide posts 304 and two bushings 305. The top ends of the two guide posts 304 are respectively connected to the two trigger parts, and the bottom ends are respectively inserted into the two bushings 305.

[0072] Optionally, the helical spring is sleeved outside the guide post 304.

[0073] In some embodiments, such as Figure 7 As shown, the limiting structure includes a first link 306 that can rotate around a first axis. The first link 306 includes a pressing part 3061, which has a limiting position that presses against the trigger plate 301 and a release position that disengages from the trigger plate 301.

[0074] In order to control the pressing part 3061 of the first link 306 to switch between the limited position and the release position, in some embodiments, referring to... Figure 7 As shown, the limiting structure also includes an electromagnetic mechanism 307, a first pin 3091, and a second connecting rod 308. One end of the first connecting rod 306 is rotatably connected to a rotating shaft seat 3092 mounted on the fixed base 100 via the first pin 3091. The electromagnetic mechanism 307 includes an electromagnet shaft 3071 capable of telescoping in a third direction. The electromagnet shaft 3071 is rotatably connected to the other end of the first connecting rod 306 via the second connecting rod 308. The third direction is as follows... Figure 7 As shown, in one embodiment, the third direction is the horizontal direction.

[0075] Optionally, an elongated hole 3062 is provided at the other end of the first connecting rod 306. The triggering mechanism 300 also includes a second pin 3093, which passes through the elongated hole 3062 and is threadedly connected to the second connecting rod 308. This allows the second pin 3093 to move within the elongated hole 3062, making the linkage mechanism composed of the first connecting rod 306 and the second connecting rod 308 more flexible.

[0076] When fall arrest is required, the electromagnetic mechanism 307 is activated, and the electromagnet shaft 3071 can retract, thereby driving the first link 306 to rotate around the first axis through the second link 308. During the rotation of the first link 306, the pressing part 3061 moves from the limiting position to the release position, and the trigger plate 301 moves upward under the drive of the first elastic member 302, thereby pushing the gripper 201 to the second position and gripping the fall arrest guide rail 30.

[0077] Optionally, the limiting structure also includes a fixing frame, which is fixed to the inner side of the second side plate 102, and the electromagnetic mechanism 307 is fixed on the fixing frame.

[0078] In some embodiments, continue to refer to Figure 8 As shown, the limiting structure also includes a second elastic element 3094. One end of the second elastic element 3094 is connected to the electromagnet shaft 3071, and the other end is connected to the fixed base 100. The second elastic element 3094 has a tendency to move the pressing part 3061 toward the limiting position. The second elastic element 3094 can tighten the electromagnet shaft 3071, thereby preventing the first connecting rod 306 from malfunctioning and accidentally disengaging from the trigger plate 301 when the electromagnetic mechanism 307 is not energized, thus preventing the clamping part from accidentally gripping the anti-fall guide rail 30.

[0079] Optionally, the second elastic element 3094 is a tension spring. A first tension spring post 3095 is provided on the electromagnet shaft 3071, and a second tension spring post 3096 is provided on the inner side of the first side plate 101. The two ends of the tension spring are hooked onto the first tension spring post 3095 and the second tension spring post 3096, respectively.

[0080] Of course, in other embodiments, in addition to using the electromagnetic mechanism 307 to provide power for the rotation of the linkage mechanism, other mechanisms can also be used to provide power for the first link 306, such as a combination of a motor and a rotating component. The rotating component can be a gear component, and the first link 306 is eccentrically connected to the gear component and rotates.

[0081] Furthermore, continue to refer to Figure 8 and Figure 9 As shown, the fall arrestor 10 also includes a detection mechanism 400 and an alarm mechanism (not shown in the figure). The detection mechanism 400 is mounted on the fixed base 100, specifically on the first side plate 101. The detection mechanism 400 can trigger the alarm mechanism to issue an alarm signal when the gripper 201 leaves its detection range. The detection mechanism 400 can promptly issue a signal to stop the drive mechanism of the loading platform 22 when the gripper 201 grips the fall arrestor rail 30, thus preventing the drive mechanism from continuing to run and damaging the shuttle system when the gripper 201 mistakenly grips the fall arrestor rail 30.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
