Description

Technical Field

[0001] This utility model relates to the field of stacking basket technology, and in particular to an automatic stacking device for medicine baskets. Background Technology

[0002] The hospital's intravenous medication preparation center (IVF center) is located in an environment designed according to international standards and drug characteristics, where professional staff prepare intravenous medications according to standard procedures. The preparation follows the principle of "one basket per prescription," with each prescription's medication stored in a separate basket, resulting in a high usage of these baskets. Due to the special nature of the medicines and the possibility of spills or leaks during handling, medicine baskets are easily contaminated. To ensure the hygiene of the medicines and the cleanliness of the preparation environment, medicine baskets must be thoroughly cleaned promptly after use. Currently, medicine baskets are mostly cleaned manually, with staff washing, soaking, disinfecting, and then drying them in water tanks in a cleaning room. This manual cleaning method has significant drawbacks: First, it consumes a lot of time and manpower, resulting in low efficiency; second, the cleaning process is difficult to supervise, and quality is uncontrollable; third, it requires a large area for drying, and the drying time is long; fourth, operators are in prolonged contact with the cleaning solution and medicine baskets, potentially suffering harm from residual medicine. In summary, existing methods for cleaning medicine baskets suffer from problems such as low efficiency, uncontrollable quality, large space occupation, and safety hazards. In order to adapt to the automated full-process cleaning of medicine baskets, there is an urgent need to provide a device for automatically stacking medicine baskets. Utility Model Content

[0003] This utility model discloses an automatic stacking device for medicine baskets to solve the above-mentioned technical problems in related technologies.

[0004] To solve the above problems, the present invention adopts the following technical solution: In a first aspect, this application provides an automatic stacking device for medicine baskets, comprising: The basket conveyor unit includes a horizontal conveyor belt and a drive mechanism that drives its operation; A lifting unit is installed on the conveying path of the horizontal conveyor belt, including a basket pallet that can be lifted vertically and a lifting mechanism that drives it to lift. The initial position of the basket pallet is lower than the plane of the horizontal conveyor belt. The stacking basket unit includes at least two rotatable stacking basket wedges arranged around the periphery of the basket body support plate, and the stacking basket wedges are provided with support portions for hanging the edges of the medicine basket; The controller is electrically connected to the drive mechanism of the basket conveying unit and the lifting mechanism of the lifting unit, and is used to control the timing of the conveying and lifting actions. The initial position of the stacked basket wedge encroaches on the lifting path space of the medicine basket. When the medicine basket is lifted by the basket support plate, the stacked basket wedge is rotated to avoid the side pressure of the medicine basket. When the medicine basket falls back after rising to the set height, the stacked basket wedge rotates in the opposite direction to reset, so that the supporting part hangs on the edge of the medicine basket to achieve suspension and positioning.

[0005] The technical solution adopted in this utility model can achieve the following beneficial effects: The automatic stacking device for medicine baskets in this application can be used for automatic stacking of medicine baskets after washing and drying. It can be used in the entire process of automatic medicine basket washing, and of course, it can also be used in other scenarios that require stacking. Specifically, it has the following advantages: (1) The automatic stacking device for medicine baskets in this application realizes automatic conveying and stacking of medicine baskets through the coordinated action of the basket conveying unit, the lifting unit and the stacking unit. With the controller, the timing can be precisely controlled, and continuous operation can be achieved, greatly reducing manual intervention and solving the problem of low efficiency of manual methods, while reducing the cost of human labor input.

[0006] (2) The automatic stacking device for medicine baskets in this application ensures a stable and consistent stacking process through standardized mechanical structure actions (the rotation angle of the stacking wedges and the lifting height are precisely controlled by the controller), avoids the randomness of manual operation, and improves the quality controllability of the post-processing of medicine baskets.

[0007] (3) The automatic stacking device for medicine baskets in this application can be integrated into the entire automatic cleaning process of medicine baskets, and can be linked with equipment such as cleaning devices and drying devices to form an automated closed loop, solve the problem of disconnection between various links in the manual process, promote the upgrading of medicine basket processing from decentralized manual operation to a highly efficient automated system, and comprehensively optimize the overall efficiency of medicine basket processing in the static dispensing center.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] The medicine baskets used in the sterile compounding center mostly feature a perforated mesh design with a flat mesh panel at the bottom and guardrails around the perimeter, with flanges at the top of the guardrails. This structure facilitates the loading and unloading of medicines, allows the cleaning solution to flow smoothly during ultrasonic cleaning, ensuring full contact with all parts of the basket, prevents medicines from falling out through the guardrails, and reduces the overall weight of the basket, making it easier to handle and clean. In terms of materials, the medicine baskets are typically made of food-grade or medical-grade plastics that are chemically resistant and have high strength, such as polypropylene (PP) or polyethylene (PE).

[0014] like Figures 1-9 As shown, this application provides an automatic stacking device for medicine baskets, comprising: The basket conveyor unit includes a horizontal conveyor belt and a drive mechanism that drives its operation; The lifting unit is located on the conveying path of the horizontal conveyor belt and includes a vertically lifting basket pallet 2 and a lifting mechanism 3 that drives its lifting. The initial position of the basket pallet 2 is lower than the plane of the horizontal conveyor belt. The stacking basket unit includes at least two rotatable stacking basket wedges 4 arranged around the periphery of the basket support plate 2, and the stacking basket wedges 4 are provided with a support portion 402 for hanging the edge of the medicine basket; The controller is electrically connected to the drive mechanism of the basket conveying unit and the lifting mechanism 3 of the lifting unit, and is used to control the timing of the conveying and lifting actions. The initial position of the stacking basket wedge 4 encroaches on the lifting path space of the medicine basket. When the medicine basket is lifted by the basket support plate 2, the stacking basket wedge 4 is squeezed laterally by the medicine basket and rotates to avoid it. When the medicine basket falls back after rising to the set height, the stacking basket wedge 4 rotates in the opposite direction to reset, so that the support part 402 hangs on the edge of the medicine basket to achieve suspension and positioning.

[0015] In some embodiments, the basket conveying unit further includes a frame 8 and a horizontal support plate 9 disposed on the top surface of the frame 8; The horizontal conveyor belt includes a first conveyor belt 10 and a second conveyor belt 11 arranged parallel to both sides of the horizontal support plate 9. The distance between the first conveyor belt 10 and the second conveyor belt 11 is less than the width of the medicine basket. When the medicine basket is placed, it satisfies the following condition: the bottom areas on both sides of the medicine basket are supported on the first conveyor belt 10 and the second conveyor belt 11 respectively. The horizontal support plate 9 has through holes 12 at the positions corresponding to the basket support plate 2, which are adapted to the size of the basket support plate 2. It can be understood that the frame 8 of the basket conveying unit, the horizontal support plate 9, and the first conveyor belt 10 and the second conveyor belt 11 on both sides can stably support and convey the medicine basket by controlling the distance between the first conveyor belt 10 and the second conveyor belt 11 to be less than the width of the medicine basket, thus avoiding tilting or falling during the conveying process. The through holes 12 of the horizontal support plate 9 provide space for the lifting and lowering of the basket support plate 2, ensuring that the lifting unit operates smoothly on the conveying path without interfering with the conveying process, thereby improving the overall stability of the medicine basket conveying and the coordination between the conveying unit and the lifting unit.

[0016] In some embodiments, two guide rods 13 are symmetrically arranged along the horizontal conveyor belt conveying path, and the two guide rods are mirror-symmetrical in structure; the two guide rods 13 are respectively arranged on the outer side of the first conveyor belt 10 and the second conveyor belt 11, and the guide rods 13 include: The main body of the rod, 1301, extends parallel to the transmission direction; The guide head 1302 is located on the feed side; The guide heads 1302 of the two guide rods 13 form an outward V-shape. This means that the two guide rods 13 are symmetrically structured, and the outward V-shape of the guide heads 1302 gradually guides the medicine basket to the center of the path during feeding, preventing tilting. The symmetrical structure of the rod body 1301 parallel to the conveying direction provides lateral restraint, thus stably guiding the medicine basket accurately into the basket support plate 2, laying the foundation for subsequent stable stacking. During discharge, the symmetrical structure of the rod body 1301 parallel to the conveying direction also provides lateral restraint for the medicine basket, preventing the stacked medicine baskets from tipping over due to a shift in the center of gravity. This optimizes the conveying trajectory throughout the process, improves positioning accuracy and stability, and enhances the overall smoothness of the device's operation.

[0017] In some embodiments, the stacking basket wedge 4 has a rod-shaped body 401, the middle of which is rotatably connected to the mounting brackets 15 on both sides of the horizontal conveyor belt via a pivot 14; the support part 402 is fixed to the first end of the rod-shaped body 401, and the support part 402 includes a guide slope 4021 for guiding the medicine basket to rise during the lifting stage and a support plane 4022 for catching the edge of the basket when the medicine basket falls back. The stacking basket unit further includes a force balancing component, which is connected to the second end of the rod-shaped body 401. The force balancing component includes: The return spring 16 provides a pulling force to raise the support portion 402; The pull-down assembly provides the pulling force to lower the support portion 402. Understandably, the rod-shaped main body 401 of the stacking wedge 4 is connected to the mounting bracket 15 via the central pivot 14. The guide slope 4021 of the support portion 402 guides the medicine basket to rise smoothly, reducing compression resistance; the support plane 4022 stably hooks onto the edge of the basket when it falls back, ensuring reliable suspension. In conjunction with the reset spring 16 of the force balance assembly and the pull-down assembly, the stacking wedge 4 can flexibly rotate to avoid compression when the medicine basket is raised, and accurately reverse its reset when the medicine basket falls back, ensuring that the support portion 402 stably hooks onto the edge of the medicine basket. The bidirectional tension adjustment of the force balance assembly makes the movement of the stacking wedge 4 smoother and more controllable, avoiding jamming or reset deviation caused by unstable force, thus improving the reliability of the stacking action.

[0018] In some embodiments, the reset spring 16 is connected to the mounting bracket 15 via the mounting plate 30.

[0019] In some embodiments, the pull-down assembly is a cylinder-driven structure, comprising a servo cylinder 17 and a connecting rod 18 connected to the output end of the servo cylinder 17. The other end of the connecting rod 18 is connected to the second end of the rod-shaped body 401. The servo cylinder 17 is electrically connected to the controller. It is understood that by adopting a cylinder-driven structure and being electrically connected to the controller, the action of the servo cylinder 17 can be precisely controlled by the controller, thereby controlling the rotation angle and reset timing of the stacking wedge block 4. The stable driving force of the servo cylinder 17, combined with the electronic control response speed, can adapt to the stacking requirements of medicine baskets of different specifications, making the action of the stacking wedge block 4 more precise and efficient, and enhancing the adaptability of the device to diverse working conditions.

[0020] In some embodiments, the basket support plate 2 has a rectangular structure, with its width matching the width of the medicine basket and its length less than the length of the medicine basket. It is understood that the width of the rectangular basket support plate 2 matching the medicine basket limits lateral displacement of the medicine basket, ensuring a correct placement posture; the shorter length allows the bottom sides of the medicine basket to be supported on the first conveyor belt 10 and the second conveyor belt 11 respectively, ensuring stable support during transport and providing reasonable force space for the lifting of the basket support plate 2, preventing the medicine basket from swaying during the transition between transport and lifting, and improving the smoothness of the connection process.

[0021] In some embodiments, there are four stacking wedges 4, each located on one side of the basket support plate 2. It is understood that the four stacking wedges 4, positioned on both sides of the basket support plate 2, can symmetrically support the medicine basket from all sides, ensuring balanced force distribution and reducing tilting caused by unilateral force. Multi-point support enhances suspension stability, better adapts to changes in the center of gravity due to increased stacking height, and improves the overall reliability of the stacking.

[0022] In some embodiments, two stacking wedges 4 located on the same side of the basket support plate 2 are connected by a connecting rod 19. The connecting rod 18 is connected to the rod-shaped body 401 of the stacking wedge 4 via the connecting rod 19. It is understood that the connection of the two stacking wedges 4 on the same side of the basket support plate 2 via the connecting rod 19, and the connection of the connecting rod 18 to the connecting rod 19, ensures greater consistency in their actions, whether the medicine basket is being squeezed and pushed aside during lifting or being reset and supported under the control of the force balance component. This avoids uneven force distribution on the medicine basket caused by deviations in the action of a single stacking wedge 4. Simultaneously, the connecting rod 19 enhances the structural integrity of the stacking wedges 4 on the same side, reducing deformation or loosening during long-term use, improving the stability and reliability of the stacking wedges 4's action, and ensuring precise and controllable stacking process.

[0023] In some embodiments, the basket support plate 2 is provided with: The first baffle 5 is vertically fixed to the feeding side of the medicine basket; The second baffle 6 is vertically fixed to the discharge side of the medicine basket; Wherein, the height of the first baffle 5 is less than the height of the second baffle 6; when the basket pallet 2 is in the feeding station: the top of the first baffle 5 is lower than or level with the horizontal conveyor belt plane, and the top of the second baffle 6 is higher than the horizontal conveyor belt plane. When the basket pallet 2 is at the discharge position, the top of the second baffle 6 is flush with the horizontal conveyor belt plane. It can be understood that the first baffle 5 and the second baffle 6 on the basket pallet 2, through height difference and positional changes, ensure that during feeding, the height of the basket pallet 2 is controlled by the controller, and the structure of the second baffle 6, which is higher than the horizontal conveyor belt plane, blocks the medicine basket, ensuring that the medicine basket accurately stops on the pallet. During discharge, the height of the basket pallet 2 is controlled by the controller, and the top of the second baffle 6 is flush with the horizontal conveyor belt plane. At this time, the bottom of the medicine basket detaches from the basket pallet 2, and the bottom of the medicine basket is located on the first conveyor belt 10, the support plate, and the second conveyor belt 11, facilitating the smooth transport of stacked medicine baskets. The low height design of the first baffle 5 avoids obstructing the medicine basket from entering the pallet, thus achieving precise positioning and smooth flow of the medicine basket during the feeding and discharging stages. Meanwhile, during the stacking and lifting stage, the first baffle 5 and the second baffle 6 form a bidirectional limit from the feeding side and the discharging side to ensure that it is within the range of action of the stacking wedge 4 and to ensure the accuracy of stacking. During the discharging stage after stacking is completed, the first baffle 5 and the second baffle 6 form a bidirectional limit from the feeding side and the discharging side to prevent the medicine basket from shifting during the process of descending to the plane of the horizontal conveyor belt.

[0024] In some embodiments, a first sensor 7 is also included to detect whether the medicine basket has reached the basket support plate 2. The first sensor 7 is electrically connected to the controller. It is understood that the first sensor 7, electrically connected to the controller, can detect in real time whether the medicine basket has reached the basket support plate 2 and transmit a signal to the controller to trigger subsequent lifting and stacking actions. This design enables the device to automatically sense the position of the medicine basket, replacing manual judgment, reducing human intervention, ensuring that actions such as conveying, lifting, and stacking are sequentially connected, and improving the automation level of the entire process.

[0025] In some embodiments, the first sensor 7 is a capacitive proximity sensor, which is embedded in the tray, and the top surface of the capacitive proximity sensor is coplanar with the bearing surface of the tray 2. It is understood that the capacitive proximity sensor embedded in the tray with its top surface coplanar with the bearing surface allows for sensitive detection of whether the medicine basket is in place, without obstructing placement of the medicine basket or causing it to wobble due to a protruding structure. Its planar design avoids physical interference between the sensor and the medicine basket, ensuring detection accuracy while not affecting the stable placement of the medicine basket on the tray.

[0026] In some embodiments, the first sensor 7 is a photoelectric sensor. Of course, the type of the first sensor 7 is not limited to that of this application, as long as it can detect in real time whether the medicine basket has reached the basket support plate 2 and transmit the signal to the controller to trigger subsequent lifting and stacking actions.

[0027] In some embodiments, the mounting frame 15 is also provided with an anti-tipping structure to prevent the stacked medicine baskets from tipping over. The anti-tipping structure on the mounting frame 15 can provide lateral support to the medicine baskets during the stacking process, preventing the medicine baskets from tipping over due to increased stacking height or external disturbance. This design enhances the overall stability of the stacked medicine baskets, reduces the risk of the medicine baskets falling or being damaged, and ensures the safety of the stacking process.

[0028] In some embodiments, the anti-tipping structure consists of two vertical support rods 1 mounted on the mounting frame 15. The two vertical support rods 1 are respectively positioned at the two corners of the medicine basket feeding side, and the cross-section of the vertical support rod 1 is L-shaped, with the apex of the L-shape of the support rod corresponding to the position of the outer corner of the medicine basket.

[0029] In some embodiments, the lifting mechanism 3 is a cylinder-driven mechanism or a motor-driven screw structure.

[0030] In some embodiments, the frame 8 has a first housing 20 on its outer side, the mounting bracket 15 has a second housing 21 on its outer side, and the mounting bracket 15 has a top cover 22 on its top, which is connected to the second housing 21.

[0031] In some embodiments, the drive mechanism of the basket conveying unit includes: Drive motor 25; The reducer 26 has its input end connected to the output shaft of the drive motor 25; The synchronous horizontal conveyor belt assembly includes a driving pulley 28, a driven pulley 29, and a drive belt 24 surrounding both, wherein: The drive wheel 28 is fixedly connected to the output shaft of the reducer 26; The first drive shaft 23 and the second drive shaft 27 are rotatably connected to the feed side and the discharge side of the mounting frame 15, respectively, and are parallel to each other; the driven wheel 29 is sleeved on the first drive shaft 23; The first transmission wheel and the second transmission wheel are coaxially sleeved on the first transmission shaft 23; The third and fourth transmission wheels are coaxially mounted on the second transmission shaft 27. The first conveyor belt 10 is mounted on the first drive wheel and the third drive wheel; The second conveyor belt 11 is fitted onto the second drive wheel and the fourth drive wheel.

[0032] The working process of the automatic stacking device for Chinese medicine baskets in this application is as follows: S1: Device initialization, each unit resets. The basket support plate 2 is in its initial position (lower than the plane of the horizontal conveyor belt, and the first baffle 5 is lower than or flush with the plane of the horizontal conveyor belt, while the second baffle 6 is higher than the plane of the horizontal conveyor belt). The stacking basket wedge 4 enters the lifting path in its initial position. The first guide rod 13 and the second guide rod 13 remain symmetrical. The first sensor 7 is on standby. The controller coordinates each component to enter the standby working state.

[0033] S2: Medicine basket feeding guide. The medicine basket enters through the feeding side. The outward V-shaped guide head 1302 of the first guide rod 13 and the second guide rod 13 guides it to correct the deviation and moves along the rod body 1301 towards the center of the conveying path, and is smoothly conveyed to the top of the basket pallet 2.

[0034] S3: The medicine basket is positioned and stopped. The medicine basket is transported to the basket pallet 2 and stops on the basket pallet 2 due to the obstruction of the second baffle 6 (which is higher than the horizontal conveyor belt plane). The first sensor 7 detects the medicine basket and transmits the signal to the controller, triggering subsequent actions.

[0035] S4: The medicine basket is lifted to avoid obstruction. The controller commands the lifting mechanism 3 to start, the basket support plate 2 rises and lifts the medicine basket. The side of the medicine basket gradually squeezes the guide slope 4021 of the stacking basket wedge block 4, forcing the stacking basket wedge block 4 to rotate and avoid obstruction. The first baffle 5 and the second baffle 6 limit the movement in both directions, ensuring that the medicine basket rises smoothly along the guide slope 4021 with a stable posture, and avoiding jamming with the support part 402.

[0036] S5: The stacking basket wedge 4 resets and supports. After the medicine basket is raised to the set height, it falls back. The stacking basket wedge 4 rotates in the opposite direction and resets under the action of the force balance component. When the medicine basket falls back to the corresponding position, the supporting plane 4022 hooks the edge of the medicine basket, completing the first medicine basket suspension and positioning. The basket support plate 2 descends and resets.

[0037] S6: Repeat the stacking operation. Subsequent medicine baskets are stacked under the suspended medicine baskets in sequence through steps S2-S5. The edge of each medicine basket is positioned by the supporting plane 4022 of the stacking wedge 4. The four stacking wedges 4 are symmetrically stressed. The guide slope 4021 plays a smooth guiding role during each lifting. The anti-tipping structure ensures the stability of the stacking.

[0038] S7: After stacking is completed and the medicine baskets are stacked to the set quantity, the lifting mechanism 3 rises and lifts the stacked medicine baskets, causing them to detach from the supporting plane 4022 of the stacking wedge block 4; the pull-down component of the force balancing mechanism pulls down the stacking wedge block 4, and the stacking wedge block 4 rotates to avoid it; then the controller controls the lifting mechanism 3 to drive the basket support plate 2 to descend to the discharge station. At this time, the top of the second baffle 6 is flush with the horizontal conveyor belt plane, and the stacked medicine baskets fall onto the first conveyor belt 10 and the second conveyor belt 11, and are conveyed to the discharge side by the guide rod 13, completing one stacking operation.

[0039] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
