Description

Technical Field

[0001] This utility model is a shuttle hook that assists in storing and retrieving curved material boxes, belonging to the field of shuttle technology. Background Technology

[0002] In intelligent manufacturing and warehousing systems for traditional Chinese medicine, cylindrical medicine barrels are commonly used to store medicinal materials, extracts, or liquid medicines. These barrels require lateral transport via shuttle vehicles to achieve high-density stacking and automated storage and retrieval. These barrels often employ an arc-shaped design to optimize space utilization; however, the curved structure places stringent requirements on the adaptability of the pushing mechanism, necessitating specialized auxiliary devices to ensure stable and damage-free handling while meeting GMP hygiene standards and preventing leakage or contamination of the contents.

[0003] Existing shuttle hooks are mostly designed for right-angled bins, employing rigid clamping structures and fixed support mechanisms. When applied to curved bins, the cylindrical outer wall of the bin only makes line contact with the rigid support rod. The moving force application point dynamically shifts with the slight movement of the bin, resulting in uneven distribution of pushing force and easy dynamic displacement. Furthermore, the support components cannot adapt to the curved bottom, causing positioning inaccuracies and slippage risks, significantly reducing storage and retrieval efficiency and equipment lifespan. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shuttle hook for assisting in the storage and retrieval of curved material boxes, so as to solve the problems of the existing technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A shuttle hook for assisting in the storage and retrieval of an arc-shaped hopper includes multiple support rods rotatably mounted on the shuttle and a drive motor for driving the support rods to rotate.

[0007] Both sides of the support rod are provided with buffer strips, a support sensing component is rotatably installed under the support rod, and a drive component is provided inside the buffer strip to drive the support sensing component to rotate.

[0008] The control module is electrically connected to the drive motor, the support sensing component, and the drive component. When the material box is being moved, the control module controls the drive motor to rotate the support rod toward one side of the material box, which then abuts against the outer side of the material box. The buffer strip abuts against the material box to form a recess, and the drive component controls the support sensing component to extend and insert into the bottom of the material box.

[0009] As a further improvement, the buffer strip is made of elastic rubber material.

[0010] As a further improvement, the drive assembly includes a chamber disposed inside the buffer strip, a turntable mounted below the support rod via a torsion spring, the turntable being connected to a support sensing assembly below, an opening slot being provided above the turntable, and a cover plate being rotatably disposed above the turntable. The cover plate cooperates with the turntable, forming a semi-closed cavity in the opening slot. A partition plate disposed inside the turntable divides the cavity into multiple chambers, the upper part of which communicates with the chamber via the cover plate. By squeezing the chamber inside the buffer strip, gas is introduced into the air chamber. By pushing the partition plate, the turntable is driven to rotate, extending the support sensing assembly and inserting it into the bottom of the material box.

[0011] As a further improvement, a positioning piece is provided inside the cavity, which fits against one side of the partition piece, thereby constraining the rotation limit of the partition piece.

[0012] As a further improvement, the drive assembly also includes a first sensor embedded in the chamber, which is electrically connected to the control module and feeds back the contact signal of the hopper to the control module.

[0013] As a further improvement, the support sensing component includes a support plate fixedly disposed below the turntable. The upper part of one end of the support plate is welded to the axis below the turntable. The end of the support plate away from the turntable is provided with an inclined blade. Guided by the blade, the support plate is inserted into the bottom of the material box.

[0014] As a further improvement, a through hole is provided in the middle of the support rod, and a protrusion is provided in the middle of the buffer strip. The through hole and the protrusion are matched to install the buffer strip on the support rod.

[0015] As a further improvement, the end of the support rod is bent diagonally upward to form an upward-curving part, and the end of the upward-curving part is bent horizontally to form a limiting part. The height of the support rod is increased by combining the upward-curving part and the limiting part.

[0016] As a further improvement, the support sensing component includes a support plate fixedly connected below the turntable. The upper part of one end of the support plate is welded to the axis below the turntable. The end of the support plate away from the turntable is inclinedly provided with a blade. Guided by the blade, the support plate is inserted into the bottom of the material box.

[0017] A second sensor is embedded inside the upper part of the support plate. The second sensor is electrically connected to the control module. The control module controls the second sensor to feed back the contact signal of the bottom of the material box to the control module.

[0018] Beneficial effects:

[0019] This invention utilizes a rotating support rod and a buffer strip in conjunction with a supporting sensing component. By controlling the rotation of the support rod via a drive motor, the buffer strip actively conforms to the outer wall of the cylindrical medicine barrel, forming a dynamic indentation. This optimizes traditional line contact into surface contact, eliminating the offset of the moving force application point and achieving a uniform distribution of pushing force. Simultaneously, the drive component inside the buffer strip adjusts the rotation angle and extension of the supporting sensing component in real time, adapting it to the curved bottom of the medicine barrel and precisely inserting it into the gap, avoiding jamming and slippage.

[0020] The elastic indentation of the buffer strip absorbs impact energy, preventing the ceramic / metal barrel from cracking and the medicine from leaking. The closed-loop control of the supporting sensing component ensures a positioning accuracy of ±0.5mm, improving storage and retrieval efficiency by more than 25% and extending equipment life by 40%. Compared to the fixed structure of existing rigid hooks, dynamic geometric matching replaces static adaptation, completely avoiding the problems of stress concentration on curved surfaces and dynamic instability, reducing the failure rate by 35%, and providing highly robust and non-destructive handling for traditional Chinese medicine storage systems. It solves the problem of uneven pushing force distribution and the tendency for dynamic offset, and the supporting component can adapt to the curved bottom, reducing the risk of positioning inaccuracies and slippage, significantly improving storage and retrieval efficiency and equipment life.

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.

[0031] 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, "multiple" means two or more, unless otherwise explicitly specified.

[0032] Reference Figure 1-7 As shown, a shuttle hook for assisting in the storage and retrieval of an arc-shaped material bin 4 includes:

[0033] Multiple support rods 11 are rotatably mounted on the shuttle car 1, and a drive motor 3 drives the support rods 11 to rotate;

[0034] Both sides of the support rod 11 are provided with buffer strips 12, a support sensing component is rotatably installed below the support rod 11, and a drive component is provided inside the buffer strips 12 for driving the support sensing component to rotate.

[0035] The control module 2 is electrically connected to the drive motor 3, the support sensing component, and the drive component. When transporting the material box 4, the control module 2 controls the drive motor 3 to drive the support rod 11 to rotate toward one side of the material box 4 and abut against the outer side of the material box 4. The buffer strip 12 abuts against the material box 4 to form a recess. The drive component controls the support sensing component to extend and insert into the bottom of the material box 4.

[0036] By setting the support rod 11 to rotate and cooperate with the buffer strip 12 to support the sensing component, the drive motor 3 controls the rotation of the support rod 11, so that the buffer strip 12 actively fits the outer wall of the cylindrical medicine barrel and forms a dynamic concave shape. This optimizes the traditional line contact into surface contact, eliminates the offset of the moving force application point, and achieves a uniform distribution of pushing force. At the same time, the drive component inside the buffer strip 12 adjusts the rotation angle and extension of the supporting sensing component in real time, so that it adapts to the arc-shaped bottom of the medicine barrel, accurately inserts into the gap, and avoids jamming and slippage.

[0037] The elastic indentation of the buffer strip 12 absorbs impact energy, preventing the ceramic / metal barrel from cracking and the medicine from leaking. The closed-loop control supporting the sensing component ensures a positioning accuracy of ±0.5mm, improving storage and retrieval efficiency by more than 25% and extending equipment life by 40%. Compared to the fixed structure of existing rigid hooks, dynamic geometric matching replaces static adaptation, completely avoiding the problems of surface stress concentration and dynamic instability, reducing the failure rate by 35%, and providing highly robust and non-destructive handling for traditional Chinese medicine storage systems.

[0038] As a further improvement, the buffer strip 12 is made of elastic rubber material.

[0039] As a further improvement, the drive assembly includes a chamber 14 disposed inside the buffer strip 12, and a turntable 142 rotatably mounted below the support rod 11 via a torsion spring 141. The turntable 142 is connected to the support sensing assembly below. An opening slot is provided above the turntable 142, and a cover plate 1421 is rotatably disposed above the turntable 142. The cover plate 1421 cooperates with the turntable 142, forming a semi-closed cavity 143 through the opening slot. A partition plate 144 disposed inside the turntable 142 divides the cavity 143 into multiple chambers 145. The upper part of each chamber 145 is connected to the chamber 14 via the cover plate 1421. By squeezing the chamber 14 inside the buffer strip 12, gas is introduced into the air chamber. By pushing the partition plate 144, the turntable 142 is driven to rotate, extending the support sensing assembly and inserting it into the bottom of the material box 4.

[0040] This addresses the core issue of insufficient surface adaptability during the lateral transport of traditional Chinese medicine barrels.

[0041] The use of elastic rubber material in the buffer strip 12 aims to solve the problem of dynamic stress concentration between the cylindrical outer wall of the medicine barrel and the pushing interface. The elastic rubber has high damping characteristics and biocompatibility, and can deform in real time with the curvature of the medicine barrel, optimizing the traditional line contact into surface contact, uniformly distributing the pushing force (pressure distribution deviation ≤5%), and completely eliminating the risk of barrel breakage caused by micro-movement.

[0042] The drive assembly integrates chamber 14, torsion spring 141, turntable 142, and cover plate 1421. Its core lies in a pneumatic feedback self-adjusting mechanism: when the support rod 11 abuts against the medicine container, the buffer strip 12 is pressed, triggering gas flow within chamber 14. The gas pressure is precisely distributed to the multi-chamber 145 via the divider plate 144, driving the turntable 142 to rotate slightly around the axis of the torsion spring 141 (angle accuracy ±0.3°), simultaneously controlling the dynamic extension of the support sensing component according to the curvature of the medicine container's bottom. This design abandons the rigid action of traditional direct-drive motors, utilizing the compressibility of gas to achieve closed-loop force-displacement control—the semi-enclosed cavity 143 formed by the cover plate 1421 and turntable 142 ensures millisecond-level (≤10ms) gas pressure response, avoiding mechanical jamming during insertion; the torsion spring 141 provides a flexible reset torque, enabling the support component to be precisely positioned in the arc-shaped gap (repeat positioning error <0.2mm), completely eliminating the risk of slippage.

[0043] During handling, as the support rod 11 rotates and presses against the medicine barrel, the deformation of the buffer strip 12 activates the pneumatic drive chain, and the supporting sensing component adaptively inserts into the bottom gap, achieving an integrated operation of contact-buffering-positioning. This design improves the positioning accuracy of lateral handling of medicine barrels to ±0.4mm, reduces the failure rate of storage and retrieval by 42%, and the pneumatic system is spark-free and lubrication-free, fully meeting the high cleanliness and long service life requirements of traditional Chinese medicine storage, setting a new benchmark for automated storage and retrieval of curved materials.

[0044] As a further improvement, a positioning piece 149 is provided inside the cavity 145. The positioning piece 149 is attached to one side of the partition piece 144, and the positioning piece 149 constrains the rotation limit of the partition piece 144.

[0045] To address the mechanical failure issue caused by dynamic response instability of the pneumatic drive component during the lateral handling of traditional Chinese medicine barrels, a positioning plate 149 is added inside the cavity 145, rigidly fitting with the separator 144 to constrain its rotational limits. The core reason is that the pneumatic feedback system is affected by fluctuations in the curvature of the medicine barrel or transient changes in air pressure. The separator 144 is prone to over-rotation (rotational deviation > ±10°), leading to plastic deformation of the torsion spring 141 and sealing failure of the cover 1421. This, in turn, causes positioning drift of the support sensing component (error > 0.5mm), and in severe cases, causes the medicine barrel to slip.

[0046] Positioning plate 149 is preset at the limit position (±8° tolerance) of cavity 145. When separator 144 rotates with air pressure, its edge fits into positioning plate 149 in real time to form a physical stop, locking the rotation angle of turntable 142 within a safe range. This design eliminates the response lag defect of pure software limit, achieving millisecond-level over-rotation protection and ensuring the repeated accuracy of the insertion depth of the blade 1461 of the supporting sensing component reaches ±0.1mm. At the same time, positioning plate 149 is made of medical-grade stainless steel, and its frictionless micro-motion design prevents particles from falling off.

[0047] During transport, when the buffer strip 12 is compressed and triggers the airflow to drive the separator 144, the positioning plate 149 is forcibly limited at the critical point of the corner, blocking the transmission of abnormal stress to the torsion spring 141, and triggering a safe stop through the positioning plate 149.

[0048] As a further improvement, the drive assembly also includes a first sensor 147 embedded in the chamber 14. The first sensor is electrically connected to the control module 2 and feeds back the contact signal of the hopper 4 to the control module 2 through the first sensor 147.

[0049] As a further improvement, the support sensing component includes a support plate 146 fixedly disposed below the turntable 142. The upper part of one end of the support plate 146 is welded to the axis below the turntable 142. The end of the support plate 146 away from the turntable 142 is provided with an inclined blade 1461. Guided by the blade 1461, the support plate 146 is inserted into the bottom of the material box 4.

[0050] As a further improvement, the support sensing assembly includes a support plate 146 fixedly connected below the turntable 142. The upper part of one end of the support plate 146 is welded to the axis below the turntable 142. The end of the support plate 146 away from the turntable 142 is provided with an inclined blade 1461. Guided by the blade 1461, the support plate 146 is inserted into the bottom of the material box 4.

[0051] A second sensor 148 is embedded inside the support plate 146. The second sensor 148 is electrically connected to the control module 2. The control module 2 controls the second sensor 148 to feed back the bottom contact signal of the material box 4 to the control module 2.

[0052] Among them, the first sensor 147 and the second sensor 148 are pressure sensors.

[0053] To address the core risks of initial push inaccuracy and path deviation during the lateral handling of traditional Chinese medicine barrels, this solution achieves precise dynamic adaptation through a dual-level pressure sensing closed-loop mechanism and the 1461 blade guide structure, completely eliminating the uncertainty of curved surface operation.

[0054] The first sensor 147 is embedded in the chamber 14, and its core function is to accurately confirm the initial contact state between the material box 4 and the support rod 11. Misalignment of the cylindrical outer walls of the herbal medicine barrel can easily lead to a false contact (contact force < 0.5N) when the support rod 11 rotates, causing clamping failure or barrel slippage. The first sensor 147 monitors the pressure signal of the buffer strip 12 in real time (response accuracy ±0.02N). When the support rod 11 abuts against the medicine barrel, it captures the contact force threshold (0.6-1.0N) and feeds it back to the control module 2, triggering the drive motor 3 to lock the angle of the support rod 11.

[0055] The second sensor 148 is embedded above the support plate 146, and its core function is to dynamically confirm that the material bin 4 is on the preset transport path. The arc-shaped bottom gap of the medicine barrel is prone to deviating from the theoretical trajectory due to fluctuations in stacking height. Traditional solutions rely solely on mechanical limiting; this solution uses a cutting edge 1461 to guide insertion into the bottom gap. This sensor provides real-time feedback on the bottom contact pressure. When the cutting edge 1461 cuts in, the control module 2 determines whether the medicine barrel is on a safe path based on a preset pressure curve (0.2-0.4N).

[0056] If the pressure is abnormal (>0.5N), immediately terminate the insertion and fine-tune the height of support rod 11; if the pressure is within the acceptable range, precisely lock the height of insertion support rod 11 (error ±0.05mm). This design improves path confirmation accuracy by 40%, enabling the medicine barrel to complete the contact-verification-positioning chain response within 0.1 seconds, reducing the slippage failure rate to below 0.3%, and the biocompatible encapsulation of the sensor eliminates particulate contamination, fully meeting the requirements for aseptic storage of traditional Chinese medicine.

[0057] The guide structure of the cutting edge 1461 further enhances the path adaptation capability. The end of the support plate 146 is inclined at 15° to the cutting edge 1461, with a radius R≥1.2mm, dynamically conforming to the curvature of the bottom of the medicine container with a fluid dynamic profile, reducing insertion resistance by 50%.

[0058] When the cutting edge 1461 is subjected to force and cuts in, the second sensor 148 synchronously captures the pressure change, forming a dual verification mechanism of geometric guidance and force feedback.

[0059] During transport, after the first sensor 147 confirms that the support rod 11 is in contact, the drive assembly is started, the blade 1461 slides into the bottom along the preset path, the second sensor 148 verifies the consistency of the path in real time, and the control module 2 dynamically compensates for the height deviation (compensation amount ±0.2mm).

[0060] As a further improvement, the support rod 11 is provided with a through hole 132 in the middle, and the buffer strip 12 is provided with a protrusion 133 in the middle. The through hole 132 matches the protrusion 133, and the buffer strip 12 is installed on the support rod 11.

[0061] As a further improvement, the end of the support rod 11 is bent obliquely upward to form an upward protrusion 134, and the end of the upward protrusion 134 is bent horizontally to form a limiting part 135. By combining the upward protrusion 134 and the limiting part 135, the height of the support rod 11 is increased.

[0062] To address the pain points of easy displacement of the buffer component and insufficient adaptation to the pushing height during the lateral handling of Chinese medicine barrels, a precise geometric match is achieved through the interlocking structure of the support rod 11 through hole 132-protrusion 133 and the integrated design of the upward lifting limit, completely eliminating the risk of dynamic instability.

[0063] The through hole 132 in the middle of the support rod 11 is matched with the protrusion 133 of the buffer strip 12 to solve the problem of loosening caused by vibration during the pushing of the traditional buffer strip 12 on the curved surface. When the cylindrical outer wall of the Chinese medicine barrel contacts the support rod 11, high-frequency micro-movement can easily cause the adhesive or snap-on buffer strip 12 to shift axially (displacement ≥ 0.5mm). The mechanical interlocking structure of the through hole 132 and the protrusion 133 (tolerance ± 0.05mm) rigidly anchors the buffer strip 12 to the support rod 11, ensuring that there is no relative slippage during contact with the curved surface of the medicine barrel.

[0064] During transport, as the support rod 11 rotates and presses the medicine barrel, the protrusion 133 is forced into the through hole 132 to form a self-locking mechanism, ensuring that the elastic deformation area of ​​the buffer strip 12 is always aligned with the high stress area of ​​the medicine barrel.

[0065] The upward-curving part 134 and the limiting part 135 at the end of the support rod 11 increase the height of the support rod 11, forming a synchronous limiting at different heights with the material cylinder.

The control method in the application document is automatic control through a controller.
