Description

Technical Field

[0001] This utility model is a dual-track guided storage and retrieval mechanism for a shuttle, belonging to the field of shuttle technology. Background Technology

[0002] Shuttle vehicles are suitable for automated warehousing, logistics distribution, and smart shelving, especially in environments with high requirements for precision, efficiency, and stability. Currently, most traditional warehousing and retrieval systems use simple robotic arms or track systems. Traditional warehousing and retrieval technologies often focus on simple mechanical connections and linear track control. In high-density warehousing, the goal is usually to maximize storage space and minimize track costs. Therefore, the more storage locations are set up laterally in the same storage and retrieval area, the higher the storage capacity of that area.

[0003] Existing shuttles can usually only perform telescopic storage and retrieval activities in one direction. If it is necessary to add unidirectional storage positions, the extension distance of the storage and retrieval plate needs to be increased. However, after the storage and retrieval plate extends a long distance, due to the lack of support points, it is difficult to effectively maintain the stability of the loading box on the storage and retrieval plate, which is prone to positional displacement, thereby affecting the overall placement accuracy.

[0017] As a further improvement, the first motor is electrically connected to the control module, and the control module controls the first motor to drive the drive wheel to rotate in the forward direction. Through the meshing of the second toothed belt and the rack, the second stage plate is controlled to move to the left.

[0018] The first motor is electrically connected to the control module. The control module controls the first motor to drive the drive wheel to rotate in the opposite direction. The second toothed belt and the rack mesh together to control the second stage plate to move to the right.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0040] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Reference Figure 1-8 As shown, a dual-track guided access mechanism for a shuttle includes: a frame 1, a bidirectional guided telescopic assembly 5 mounted on the frame 1, and a first drive assembly that drives the bidirectional guided telescopic assembly 5 to extend to the left / right.

[0042] The bidirectional guide telescopic assembly 5 includes several sets of limiting rods 61 for limiting the material box 4, and a second drive assembly for driving the limiting rods 61 to extend / retract.

[0043] Control module 3, which is electrically connected to the first drive component and the second drive component;

[0044] The bidirectional guide telescopic assembly 5 includes a set of primary plates 63 that are laterally movably mounted on the frame 1 and secondary plates 65 that are slidably mounted on the inner side of the primary plates 63.

[0045] The control module 3 controls the first driving component to drive the primary plate 63 and the secondary plate 65 to extend to the left / right side in stages and surround the target material box 4. The control module 3 also controls the second driving component to drive the limiting rod 61 to extend and limit the material box 4, and cooperates with the first driving component to control the secondary plate 65 and the primary plate 63 to retract in opposite directions in stages.

[0046] Existing shuttle systems typically employ unidirectional telescopic pallets and tracks. This design presents stability and efficiency issues in high-density storage and tasks requiring high precision. For example, in traditional systems, the limited support points after the pallet extends a long distance can easily cause the loading bin to shift, affecting storage accuracy and subsequent operations. Especially when additional storage space is needed, the existing design often requires extending the pallet's extension distance, which exacerbates instability and impacts work efficiency and accuracy.

[0047] By introducing the bidirectional guided telescopic component 5, the shuttle can perform telescopic storage and retrieval operations in both left and right directions. This improves the utilization rate of storage space, allows for flexible selection of the storage and retrieval direction as needed, and optimizes spatial layout and operational efficiency.

[0048] By adding multiple sets of limit rods 61 and cooperating with the second drive assembly for precise control, these limit rods can stabilize the positioning of the material box 4 during storage and retrieval, prevent positional deviation during long-distance extension and retraction, and improve the accuracy and stability of the storage and retrieval process.

[0049] The bidirectional telescopic assembly 5, employing a laterally movable primary plate 63 and a sliding secondary plate 65, ensures that the material bin 4 is safely and precisely surrounded and supported during storage and retrieval. The control module 3 controls the extension and retraction of these two plates via electrical connection, ensuring no unnecessary shaking or displacement during operation.

[0050] Advantages over existing technologies:

[0051] Existing unidirectional storage and retrieval systems are prone to instability during extension and retraction, especially when the storage plate extends, which can cause the hopper to shift and affect accuracy. This solution, however, employs a bidirectional guiding design and precise limit rod control, ensuring the stability of the hopper during storage and retrieval and significantly improving accuracy.

[0052] Existing systems typically rely on unidirectional track layouts, which limits space utilization in high-density storage environments. This solution, however, utilizes a bidirectional guided telescopic assembly 5 in conjunction with a flexible control module 3, enabling more efficient use of storage space while reducing costs associated with track expansion.

[0053] This solution offers the flexibility of bidirectional access, while traditional systems typically only handle unidirectional access. This dual-track design allows for adjustments to storage locations as needed, effectively addressing evolving warehousing demands and material management requirements, thus increasing the system's scalability and adaptability.

[0054] The control module 3 enables precise control of the primary plate 63, the secondary plate 65, and the limit rod 61, ensuring that the shuttle maintains accuracy without any interference during storage and retrieval. The advantage of this precise control is that it significantly reduces errors and improves overall operational efficiency.

[0055] To control the smooth extension of the primary plate 63 to the left / right, a toothed plate 631 is provided below the primary plate 63;

[0056] The first drive assembly includes a gearbox motor assembly 632 fixedly mounted on the frame 1, a drive shaft 633 inserted into the gearbox motor assembly 632, and drive gears 634 mounted at both ends of the drive shaft 633. The gearbox motor assembly 632 is electrically connected to the control module 3.

[0057] Two sets of drive wheels 635 are rotatably mounted on the frame 1. The two drive wheels 635 in the same set are connected by a first toothed belt 636. The outer side of the first toothed belt 636 meshes with the toothed plate 631 and the drive gear 634.

[0058] Since the primary plate 63 needs to extend smoothly on the frame to perform storage and retrieval operations, if the primary plate 63 relies directly on ordinary linear drive, it may be affected by friction, misalignment, and uneven power, resulting in instability or even jamming during extension. By setting the gear plate 631 to cooperate with the transmission system and utilizing the meshing action of gears, the smoothness of the extension process can be greatly improved.

[0059] The toothed plate being positioned below the primary plate allows the drive and control systems to precisely control the plate's extension and retraction via gears and belts, without the instability issues caused by traditional sliding friction.

[0060] Simultaneously, the combination of the gearbox motor unit 632 and the drive shaft 633 enables efficient power transmission. Through this design, the gearbox motor unit converts electrical energy into mechanical energy and transmits it to the transmission system, thereby driving the extension of the primary plate. The transmission system ensures stable power transmission through the cooperation of gears and toothed belts.

[0061] Gears and toothed belts ensure precise synchronization during the drive process, avoiding extension errors caused by sliding friction or inaccurate mechanical parts in traditional electric drive devices. The meshing between the transmission wheel 635 and the toothed belt 636 ensures the accuracy of power transmission, enabling the first-stage plate 63 to extend precisely according to the instructions of the control module.

[0062] The gearbox motor assembly 632 includes a gearbox welded to the frame 1 and a motor fixedly installed at one end of the gearbox. The gearbox is usually equipped with two sets of meshing gears, one of which is fixed to the output shaft of the motor, and the other gear is welded to the transmission shaft 633 and is coaxial with the transmission shaft 633. Since the gearbox motor assembly 632 is a conventional configuration, it will not be described in detail.

[0063] To improve the stability of the extended primary plate 63, a set of positioning plates 64 are fixedly installed in the middle of the frame 1. The upper and lower edges of the positioning plates 64 facing the primary plate 63 are provided with multiple sets of first guide wheels 641. The upper and lower edges of the primary plate 63 facing the positioning plates 64 are provided with a set of first guide strips 642. Two first guide strips 642 are provided with first grooves 643 facing opposite sides, and the first guide wheels 641 abut against the first grooves 643.

[0064] To improve the stability of the extension of the secondary plate 65, multiple sets of second guide wheels 651 are provided on the upper and lower edges of the primary plate 63 facing the secondary plate 65, and a set of second guide strips 652 are provided on the upper and lower edges of the secondary plate 65 facing the primary plate 63. Two second guide strips 652 are provided with second grooves 653 facing adjacent sides, and the second guide wheels 651 abut against the second grooves 653.

[0065] The positioning plate 64 and the first guide bar 642, first guide wheel 641, second guide bar 652 and second guide wheel 651 on the side of the secondary plate 65 form a double-rail lateral unfolding posture with opposite receiving directions, which greatly improves the support stability.

[0066] The first drive assembly includes a set of drive wheels 654 rotatably mounted on the first-stage plate 63. Two drive wheels 654 are connected by a second toothed belt 655. A first motor 66 is fixedly mounted on the first-stage plate 63 to control the rotation of the drive wheels 654. The output shaft 22 of the first motor 66 is fixedly connected to the shaft of one of the drive wheels 654. A rack 67 is fixedly mounted on the second-stage plate 65 facing the first-stage plate 63. The rack 67 meshes with the second toothed belt 655.

[0067] As a further improvement, the first motor 66 is electrically connected to the control module 3. The control module 3 controls the first motor 66 to drive the drive wheel 654 to rotate in the forward direction. The second toothed belt 655 is engaged with the rack 67 to control the secondary plate 65 to move to the left.

[0068] The first motor 66 is electrically connected to the control module 3. The control module 3 controls the first motor 66 to drive the drive wheel 654 to rotate in the opposite direction. The second toothed belt 655 is engaged with the rack 67 to control the secondary plate 65 to move to the right.

[0069] To improve the stability of the primary and secondary plates, primary plate 63 and secondary plate 65 may be affected by uneven forces during extension, leading to unstable movement or positional deviation. By installing a positioning plate 64 in the middle of the frame 1, along with guide wheels 641 and guide strips 642, friction and instability between the primary plate 63 and the frame can be effectively avoided, ensuring smooth and stable movement.

[0070] The positioning plate 64, through the cooperation of multiple first guide wheels 641 and first grooves 643, forms a precise guide track, ensuring that the first-stage plate 63 extends stably along the correct trajectory. Similarly, the extension of the second-stage plate 65 is also precisely controlled by second guide wheels 651 and second grooves 653.

[0071] To enhance support stability through dual-rail lateral deployment, the first-stage plate 63 and the second-stage plate 65 are designed with first guide bar 642 and second guide bar 652, respectively, forming a dual-rail lateral deployment posture. The two guide wheels engage with their respective grooves, controlling the plate movement while preventing any unnecessary lateral offset. This dual-rail system improves the support stability of the plates, ensuring they remain vertical or horizontal throughout the deployment process, reducing structural deformation and excessive vibration.

[0072] The dual-track lateral deployment design avoids the skew problem that may be caused by a single track, and greatly improves the stability of the primary and secondary plates under different working conditions.

[0073] To ensure the smooth extension of the secondary plate 65 on the primary plate 63, a first drive assembly is employed, including a drive wheel 654 mounted on the primary plate and a cooperating second toothed belt 655. Through precise electric control, the secondary plate 65 can move precisely to the left or right, thereby meeting different operational requirements.

[0074] The first motor 66 works in conjunction with the rack 67 via the toothed belt 655, further enhancing the precise transmission between the secondary plate 65 and the primary plate 63. The meshing of the rack 67 and the toothed belt 655 ensures the stability of power transmission and can efficiently control the movement of the secondary plate 65, avoiding transmission inaccuracies caused by friction and wear.

[0075] Through this multi-layered guidance and drive design, the primary board 63 and the secondary board 65 not only possess higher stability but also maintain lower wear during long-term, high-frequency use. This reduces malfunctions caused by friction and motion instability, extending the equipment's lifespan.

[0076] To achieve precise limit control of the material box, the limit rod 61 is rotatably mounted inside the secondary plate 65. The second drive assembly includes a second motor 62 whose output end is fixedly connected to the bottom of the limit rod 61. The second motor 62 is fixedly mounted on the side of the secondary plate 65 facing the primary plate 63. The second motor 62 is electrically connected to the control module 3, and the control module 3 controls the second motor 62 to drive the limit rod 61 to rotate in the forward / reverse direction.

[0077] The rotation of the limit rod 61 is controlled by the second motor 62, enabling precise positioning and limiting functions. By controlling the rotation direction of the second motor (forward / reverse), the limit rod can be precisely adjusted to ensure that the equipment or system moves within a predetermined range or angle during operation, preventing it from exceeding the set range.

[0078] Example 2;

[0079] Reference Figure 1-8 As shown, this embodiment is basically the same as embodiment 1, except that it is based on embodiment 1 and further improved. Specifically, it also includes an auxiliary limiting component disposed in the middle of the frame 1 for adsorbing the bottom of the material box 4, and an identification unit disposed in the middle of the frame 1 for identifying the working state of the limiting rod 61. The identification unit is electrically connected to the control module.

[0080] Move the material box 4 above the auxiliary limiting component;

[0081] The identification unit identifies that the limiting rod 61 is in the extended state, and the control module 3 drives the auxiliary limiting component to adsorb the bottom of the material box 4.

[0082] The frame 1 includes a base plate 2 welded and fixed to its upper center. The identification unit includes a plurality of first sensors 68 embedded on the two sides of the base plate 2 facing the secondary plate 65. The spacing between the plurality of first sensors 68 is consistent with the spacing between the plurality of limiting rods 61. When the primary plate 63 and the secondary plate 65 are reset, the unfolded limiting rods 61 are located directly above the first sensors 68.

[0083] The auxiliary limiting component includes multiple sets of adsorption ports 681 disposed on the base plate 2 and an air pump 682 fixedly installed below the base plate 2. The multiple adsorption ports 681 are connected to the air intake port of the air pump 682 through pipes. Each set of adsorption ports 681 is located between two first sensors 68. A second sensor 683 is provided corresponding to each set of adsorption ports 681. The second sensor 683 is embedded in the base plate 2.

[0084] To further improve the stability of the material bin during transfer, an auxiliary limiting component, including multiple suction ports and an air pump, is used to precisely suction the bottom of the material bin when needed, ensuring that the bin does not shift during transportation. The cooperation of the pipeline and air pump ensures that the suction ports accurately suction the bottom of the material bin, avoiding operational instability caused by displacement or slippage.

[0085] The combination of the air pump and the adsorption port utilizes the principle of negative pressure to make the adsorption effect stronger and more stable, ensuring that the material box remains fixed throughout the transportation and operation process, avoiding errors caused by movement, vibration or misoperation.

[0086] The identification unit accurately identifies the working state of the limiting rod 61 through multiple first sensors 68. This design can monitor the state of the limiting rod in real time and determine whether it is in the extended state, which is very important for the automated control system. Through the coordinated work of the control module 3 and the sensors, the auxiliary limiting component can be automatically driven to adsorb the bottom of the material box when the limiting rod is in the extended state, thereby realizing automated operation and reducing manual intervention.

[0087] Thanks to the collaboration between the identification unit and the control module, the system can sense the state of the limit lever in real time and react accordingly. Through precise control and feedback mechanisms, it can quickly respond to external changes, improving the system's response speed and accuracy.

[0088] By ensuring that the spacing between multiple first sensors 68 and the limit rod 61 is consistent, the identification unit can accurately detect the state of the limit rod. Through connection with the control module 3, the sensors can determine the state when the limit rod resets, thereby driving other components to operate accurately. This precise sensor layout and control effectively avoids misoperation and ensures the reliability and accuracy of operation.

[0089] Each set of adsorption ports is equipped with a second sensor 683. These sensors can accurately reflect the working status of the adsorption ports, further improving the accuracy of the adsorption process. This ensures that each adsorption port can work accurately as needed, and that the material box can be reliably adsorbed and fixed.
