Description

Technical Field

[0001] This utility model relates to the field of material transportation system technology, and in particular to a material separation device and a material transportation system. Background Technology

[0002] In automated pharmaceutical manufacturing, material transfer and process coordination are crucial for ensuring production efficiency and material safety. Materials are typically transported in batches within carriers. Upon arrival at the target workstation, automated separation is required. The materials then proceed to subsequent processes, while the empty carriers are recycled and reused to create a closed-loop, highly efficient production transport system that meets the industry's requirements for continuity and cleanliness.

[0003] The mainstream solution in the current technology is a gripping separation device with a multi-axis manipulator as its core. Its core structure includes a multi-axis motion module, an end-effector gripping component, a position detection module, and a control system. During operation, the main conveyor belt delivers the carrier to the separation station. The position detection module collects the material coordinates and feeds them back to the control system. The control system drives the manipulator to move above the material, and the end-effector gripping component removes the material and transfers it to the subsequent conveyor line. Empty carriers enter the recycling channel.

[0004] However, robotic arms need to complete multiple complex movements from positioning and grasping to transfer, and the overall movement path is relatively long, which increases the time required for a single separation operation. This makes it difficult to meet the high efficiency requirements for material turnover in pharmaceutical automated production, especially in the scenario of continuous processing of batch materials, where the efficiency shortcoming is even more prominent.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

[0052] Please see Figures 1 to 3 This embodiment provides a material separation device for separating materials from a carrier and transporting the separated materials and the empty carrier to their respective locations.

[0053] The material separation equipment includes a frame 1, a lifting mechanism 2, a gripping mechanism 3, a conveying mechanism 4, a first conveying line 5, and a second conveying line 6. The conveying mechanism 4 is configured to carry and transport materials and carriers along a preset path. The lifting mechanism 2 is mounted on the frame 1 and configured to drive the conveying mechanism 4 to rise and fall, enabling the conveying mechanism 4 to stop at at least two preset height positions. The gripping mechanism 3 is mounted on the frame 1 and located above the conveying mechanism 4, and is configured to grip the materials on the conveying mechanism 4. The first conveying line 5 is mounted on the frame 1 and corresponds to one of the preset height positions to receive and transport the separated materials conveyed by the conveying mechanism 4. The second conveying line 6 is mounted on the frame 1 and corresponds to another preset height position to receive and transport the separated empty carriers conveyed by the conveying mechanism 4.

[0054] During separation, the conveying mechanism 4 first receives the externally supplied carrier carrying materials and conveys the carrier and materials together along a preset path to directly below the gripping mechanism 3. Then, the gripping mechanism 3 grips and holds the materials on the conveying mechanism 4 in place. The lifting mechanism 2 drives the conveying mechanism 4 to move to one of the preset height positions that matches the second transport line 6. The conveying mechanism 4 then conveys the empty carrier to the second transport line 6. Subsequently, the gripping mechanism 3 releases the materials and places them back on the conveying mechanism 4. Then, the lifting mechanism 2 drives the conveying mechanism 4 to move to another preset height position that matches the first transport line 5. The conveying mechanism 4 then conveys the materials to the first transport line 5. This completes the separation of the materials and the carrier, and the materials and the carrier are respectively conveyed to the next process by the first transport line 5 and the second transport line 6.

[0055] With this configuration, the gripping mechanism 3 is positioned above the conveying mechanism 4, allowing for material gripping and holding without long-distance movement. The lifting mechanism 2 only needs to drive the conveying mechanism 4 to switch between preset heights that match the second conveying line 6 and the first conveying line 5, eliminating the need for long-distance back-and-forth movement of the robotic arm, shortening the overall movement path, and reducing the time required for a single separation operation. This adapts to the high-efficiency requirements of pharmaceutical production for material turnover speed.

[0056] Meanwhile, the conveyor mechanism 4 receives the carrier and transports it to the separation station, the gripping mechanism 3 grips and releases the material, the lifting mechanism 2 drives the conveyor mechanism 4 to switch heights, and the conveyor mechanism 4 transports empty carriers and carriers carrying materials respectively. Each link does not need to rely on the long-distance movement of the robotic arm, the action connection is faster, the action gap in batch processing is reduced, the continuous processing capacity of batch materials is improved, and thus the efficiency is improved.

[0057] To further optimize the accuracy and smoothness of the material gripping action, the lifting mechanism 2 drives the conveying mechanism 4 to stop at three preset height positions, with the highest preset height position corresponding to the position of the gripping mechanism 3 on the frame 1. When the lifting mechanism 2 drives the conveying mechanism 4 to the highest preset height position, the gripping mechanism 3 can grip the material carried by the conveying mechanism 4.

[0058] Understandably, by aligning the highest preset height position of the conveying mechanism 4 with the setting position of the gripping mechanism 3, the gripping mechanism 3 can grip materials without adjusting its height, only needing to complete the gripping action, thus further shortening the time consumed in a single gripping operation and better meeting the high efficiency requirements of pharmaceutical production for material turnover speed.

[0059] It is also understandable that the gripping mechanism 3 only needs to be able to grip and release materials. The movement is more stable, and the connection gap caused by height adjustment is reduced. In the scenario of continuous processing of batch materials, the risk of jamming caused by movement deviation can be reduced, and the overall operation efficiency can be improved.

[0060] In this embodiment, the gripping mechanism 3 includes a suction cup disposed above the conveying mechanism 4. The suction cup is used to adsorb the material carried on the conveying mechanism 4 to achieve gripping. The suction cup adsorbs through surface contact, which results in a more uniform pressure distribution compared to the point / line contact of mechanical gripping. This effectively protects the integrity of the material and avoids damage to the packaging or the contents.

[0061] It should be noted that the gripping mechanism 3 also needs to include other supporting components such as a negative pressure generating device, connecting pipes, and control elements. The negative pressure generating device generally uses a vacuum pump or vacuum generator to generate negative pressure. One end of the connecting pipe is connected to the interface of the suction cup, and the other end is connected to the negative pressure generating device to generate negative pressure. The control element is an existing solenoid valve, which is used to control the opening and closing of the connecting pipe, thereby adjusting the air pressure state of the suction cup.

[0062] Furthermore, among the three preset height positions, the preset height position corresponding to the second transport line 6 is the lowest of the three preset height positions, so that when the conveying mechanism 4 descends from the highest preset height position to the lowest preset height position, the lifting mechanism 2 can descend along a one-way path without switching the up and down direction midway, shortening the action stroke and response time of the lifting mechanism 2, further reducing the total time of a single separation operation, and adapting to the high efficiency requirements of pharmaceutical production for material turnover speed.

[0063] Meanwhile, the highest preset height position (grabbing position), the middle preset height position corresponding to the first transport line 5, and the lowest preset height position (second transport line 6) form a top-down layered layout, so that the grabbing mechanism 3, the first transport line 5, and the second transport line 6 do not cross or interfere with each other in space, avoid action conflicts between different conveying links, and improve the rationality of the overall layout of the equipment.

[0064] In addition, the conveying mechanism 4 has a more continuous motion process of descending from the highest position to the lowest position and then resetting and rising to the highest position, reducing the need for back-and-forth adjustments in the lifting direction, further shortening the action gap in batch material processing, and alleviating the problem of insufficient batch processing efficiency in the prior art.

[0065] Specifically, the gripping mechanism 3 also includes a position detection element 31 mounted on the frame 1. The position detection element 31 is used to detect whether the conveying mechanism 4 has reached the highest preset height position. When the position detection element 31 detects that the conveying mechanism 4 has reached the highest preset height position, the position detection element 31 can trigger the gripping mechanism 3 to start, so as to perform a gripping operation on the material on the conveying mechanism 4.

[0066] Understandably, by detecting the highest preset height position of the conveying mechanism 4 through the position detection component 31, it is possible to immediately confirm whether the conveying mechanism 4 is in the gripping adaptation position, avoid empty gripping, mis-gripping, or material damage caused by misalignment between the material and the gripping mechanism 3, ensure gripping accuracy, and meet the requirements of pharmaceutical production for material handling precision.

[0067] It should be noted that the position detection component 31 can be a photoelectric sensor or an inductive proximity switch, both existing technologies. If a photoelectric sensor is used, its transmitter and receiver are respectively set at corresponding positions on the frame 1. When the conveying mechanism 4 rises to the highest preset height, the components of the conveying mechanism 4 will block or reflect the light beam, causing a change in the sensor's received signal. If an inductive proximity switch is used, it determines the position by detecting changes in the magnetic field of the metal conveying mechanism 4. After detecting that the conveying mechanism 4 has reached the highest preset height, the position detection component 31 will output a trigger signal to the control system, thereby activating the gripping mechanism 3 to perform the gripping operation.

[0068] Specifically, the lifting mechanism 2 includes a guide member 21, a support frame 22, and a drive assembly 23. The guide member 21 is disposed on the frame 1 and extends vertically. The support frame 22 is slidably engaged with the guide member 21 and can rise and fall along the guide member 21. The support frame 22 is configured to carry and convey the mechanism 4. The drive assembly 23 is disposed on the frame 1 and is configured to drive the support frame 22 to rise and fall along the guide member 21.

[0069] As can be seen from the above, the guide component 21 is fixed to the frame 1 in the vertical direction, providing precise guidance for the support frame 22, so that the support frame 22 drives the conveying mechanism 4 to move along the preset vertical path when it is raised and lowered, avoiding deviation or shaking, and ensuring the positioning accuracy of the conveying mechanism 4 at each preset height position, thus providing a foundation for the gripping mechanism 3 to accurately grip materials and the conveying mechanism 4 to accurately connect with the first transport line 5 and the second transport line 6.

[0070] In addition, the sliding fit between the support frame 22 and the guide member 21 and the support conveying mechanism 4 can improve the structural stability of the lifting process. Especially when batch materials are processed continuously, the conveying deviation caused by unstable support can be reduced.

[0071] It is worth noting that the guide component 21 can be a guide rail or guide post extending in the vertical direction, which is fixed to the frame 1 by bolts or other connecting parts. The cross-section of the guide rail can be T-shaped, rectangular, or circular, while the guide post can be cylindrical, with a smooth surface to reduce sliding friction. The support frame 22 can be a frame structure, with sliders or sleeves adapted to the guide component 21 on one or both sides. The inner shape of the slider matches the cross-section of the guide rail, and the inner diameter of the sleeve matches the outer diameter of the guide post. Sliding engagement is achieved by the engagement of the slider and the guide rail or the sleeve and the guide post. The top or side of the support frame 22 has a mounting surface for fixing the conveying mechanism 4 with fasteners, ensuring that the conveying mechanism 4 rises and falls synchronously and stably with the support frame 22.

[0072] Furthermore, the drive assembly 23 includes a counterweight 231, a flexible transmission component 230, a fixed pulley 232, and a drive wheel 233. The fixed pulley 232 is disposed on the frame 1 and located above the support frame 22. The flexible transmission component 230 is wound around the fixed pulley 232, with one side connected to the support frame 22 and the other side connected to the counterweight 231. The drive wheel 233 is configured to wind around or release the flexible transmission component 230 on the side where the support frame 22 is located.

[0073] With this configuration, the counterweight 231 can balance the weight of the support frame 22, the conveying mechanism 4 and the material it carries, which greatly reduces the driving force required for the drive wheel 233 to drive the support frame 22 to rise and fall. This reduces equipment energy consumption, reduces wear on the drive wheel 233, extends the service life of the drive assembly 23, and avoids impacts caused by excessive driving force during lifting and lowering.

[0074] In addition, the drive wheel 233 is driven by the flexible transmission component 230 on the side of the support frame 22. By controlling the rotation speed of the drive wheel 233, the lifting speed and stop position of the support frame 22 can be precisely adjusted, adapting to the lifting needs of different weight vehicles and materials, and improving the flexibility and accuracy of lifting control.

[0075] It should be noted that the drive wheel 233 preferably adopts a cylindrical wheel body, and the wheel axle is connected to the output shaft of the drive motor through a coupling. The circumferential surface of the wheel body is provided with grooves or teeth adapted to the flexible transmission component 230, which can form meshing or friction transmission with the flexible transmission component 230 (such as a timing belt or chain). When the drive motor starts, the power is transmitted to the drive wheel 233 through the wheel axle. The drive wheel 233 rotates and drives the flexible transmission component 230 wound on it to move. In turn, the flexible transmission component 230 pulls or releases the support frame 22, realizing the lifting and lowering drive of the support frame 22 along the guide member 21.

[0076] To improve the stability of the counterweight 231 during lifting, the drive assembly 23 also includes a guide rod 234 and a roller 235. The guide rod 234 is mounted on the frame 1 and extends along the lifting path of the counterweight 231. The roller 235 is rotatably mounted on the counterweight 231, and the roller 235 rolls in cooperation with the guide rod 234 to guide the counterweight 231 to lift smoothly along the extension direction of the guide rod 234, thereby providing motion guidance for the counterweight 231. The rolling cooperation between the roller 235 and the guide rod 234 can limit the lateral offset or sway of the counterweight 231 during lifting, preventing the counterweight 231 from generating lateral tension on the flexible transmission component 230 due to offset, thereby reducing friction and wear between the flexible transmission component 230 and the fixed pulley 232 and drive wheel 233, extending the service life of the transmission components, and ensuring the stability of power transmission.

[0077] Specifically, the conveying mechanism 4 includes multiple parallel and spaced conveying rollers 41 and a conveying drive component that drives the multiple conveying rollers 41 to rotate. The multiple conveying rollers 41 together form a bearing surface for carrying materials and carriers. The multiple parallel and spaced conveying rollers 41 have line contact with the carrier and materials, with a small and uniformly distributed contact area, which can reduce frictional resistance during the conveying process, allowing the carrier and materials to move smoothly along the preset path, avoiding deviation caused by uneven friction, and ensuring that they are accurately conveyed to the area directly below the gripping mechanism 3, providing a stable foundation for subsequent gripping actions.

[0078] The conveying drive typically includes a drive motor and a transmission assembly. The drive motor can be a speed-adjustable motor to adapt to different conveying speed requirements. The transmission assembly commonly consists of sprockets and chains or synchronous belts and pulleys, which are connected to the sprockets or pulleys at the ends of each conveying roller 41 via chains or synchronous belts. During operation, the drive motor outputs power, which drives multiple conveying rollers 41 to rotate synchronously and in the same direction via the transmission assembly, so that the carrier and materials on the bearing surface are smoothly conveyed along a preset direction.

[0079] This embodiment also provides a material transport system, which includes a feeding conveyor line 100 and the aforementioned material separation device. The feeding conveyor line 100 is configured to transport a vehicle carrying material. The material separation device is configured to receive the vehicle carrying material, and is further configured to separate the material from the vehicle, and transport the separated material and the empty vehicle to corresponding locations respectively.

[0080] Understandably, the feeding conveyor line 100 can be seamlessly connected with the material separation equipment, continuously transporting the carriers containing materials to the conveying mechanism 4 of the material separation equipment without manual intervention. This avoids efficiency losses and material contamination risks caused by manual transfer, and meets the requirements of pharmaceutical production for continuity and cleanliness.

[0081] It should be noted that the feeding conveyor line 100 can be any of the existing conveying structures, and this embodiment does not impose any requirements or restrictions on it.

[0082] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
