Description

Technical Field

[0001] This application relates to the field of pharmaceutical powder weighing equipment, and in particular to a sensitive pharmaceutical powder weighing device. Background Technology

[0002] Explosive powders and other sensitive powders pose a high risk, therefore, extreme caution must be exercised during material handling and weighing, and safety procedures must be strictly followed to prevent accidents. However, relying on manual handling and weighing of powders inevitably introduces significant subjectivity and uncertainty, and non-standard operations still occur from time to time. This not only leads to lower weighing accuracy and overall safety, resulting in significant risks and hidden dangers, but also results in low operational efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, this application proposes a sensitive powder picking and weighing device that can automatically pick up and weigh powder, thereby improving operational efficiency and reducing operational risks.

When the material picking mechanism moves from its initial position toward the material bin, the guide mechanism is in a first position, and the guide mechanism forces the picking rod to deflect downward and extend into the material bin to pick up the material; when the material picking mechanism moves away from the material bin back to its initial position, the guide mechanism is in a second position, and the picking rod moves horizontally. The material unloading cylinder is equipped with a material picking rod that quantitatively picks up material from the material hopper and pours it into the unloading cylinder; when the material picking mechanism is in its initial position, the material picking rod is located above the unloading cylinder. The weighing mechanism is located below the unloading cylinder; Conveyor line; Material feeding mechanism; The transfer mechanism picks up the receiving cup to receive the powder in the unloading cylinder and drives the receiving cup to switch between the weighing mechanism, the pouring mechanism, and the conveyor line.

After the material handling rod pours the powder into the unloading cylinder, the transfer mechanism clamps the receiving cup to receive the powder in the unloading cylinder and automatically transfers it to the weighing mechanism. Subsequently, the powder with the correct weight is sent to the conveyor line, while the powder with the incorrect weight is sent to the unloading mechanism for recycling. This device realizes automatic material handling and weighing screening of sensitive powders, with strong operational standardization, significantly improving work efficiency and reducing operational risks.

[0021] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. The embodiments of this application may omit unnecessary detailed descriptions. For example, detailed descriptions of well-known matters and repeated descriptions of actually identical structures may be omitted. This is to avoid making the following description unnecessarily lengthy and to facilitate understanding by those skilled in the art.

[0023] In this application, the technical features described in an open-ended manner include both closed technical solutions consisting of the listed features and open technical solutions that include the listed features.

[0024] Reference Figures 1 to 8This application discloses a sensitive drug powder weighing and dispensing device, including a working platform 100, a material bin 200, a dispensing mechanism 300, a guiding mechanism 400, a discharge cylinder 340, a weighing mechanism 500, a conveyor line 800, a pouring mechanism 600, and a transfer mechanism 700. The material bin 200 is fixedly installed on the working platform 100 for storing drug powder. The dispensing mechanism 300 is slidably installed on the working platform 100 along a first direction, thereby being able to move towards the material bin 200 to perform a dispensing operation, or move away from the material bin 200 to return to its initial position. The dispensing mechanism 300 includes a dispensing rod 310 for scooping up drug powder. The guiding mechanism 400 is slidably installed on the working platform 100 along a second direction, the first direction and the second direction being perpendicular to each other, and both the dispensing mechanism 300 and the guiding mechanism 400 are horizontally sliding. For example, if the first direction is set to a left-right direction, then the second direction is configured as a front-back direction.

[0025] Specifically, such as Figure 2 and Figure 6 As shown, the working platform 100 is equipped with a first slide rail 110 and a second slide rail 120. The length directions of the first slide rail 110 and the second slide rail 120 are perpendicular to each other. The material picking mechanism 300 is slidably installed on the first slide rail 110, and the guiding mechanism 400 is slidably installed on the second slide rail 120, forming two independent sliding degrees of freedom.

[0026] In some embodiments of this application, the guide mechanism 400 has a first position and a second position. When the guide mechanism 400 is in the first position, it is connected to the picking rod 310 on the picking mechanism 300. When the guide mechanism 400 is in the second position, it is disconnected from the picking rod 310. When the picking mechanism 300 moves from its initial position toward the material bin 200, the guide mechanism 400 remains in the first position. The guide mechanism 400 forces the picking rod 310 to deflect downwards, allowing the guide part to smoothly extend into the interior of the material bin 200 to complete the scooping action of the powder. The downward deflection design of the picking rod 310 allows it to contact the powder by "scooping" rather than "collision, squeezing, or friction," significantly reducing the risk of sensitive powder being ignited during the picking process and greatly improving the safety and reliability of the operation.

[0027] When the feeding mechanism 300 carries the acquired powder to its initial position away from the material bin 200, the guiding mechanism 400 switches to the second position. In this state, the feeding rod 310 maintains horizontal movement, smoothly conveying the acquired powder to the designated position, completing the entire feeding cycle.

[0028] In some embodiments of this application, the material handling mechanism 300 further includes a discharge cylinder 340, see reference Figure 3As shown, the picking rod 310 quantitatively picks up material from the material bin 200 and pours it into the unloading cylinder 340; when the picking mechanism 300 is in the initial position, the picking rod 310 is located above the unloading cylinder 340.

[0029] In some embodiments of this application, the transfer mechanism 700 grips the receiving cup for receiving medicinal powder and drives the receiving cup to transfer between the weighing mechanism 500, the unloading mechanism 600, and the conveyor line 800. The weighing mechanism 500 is located below the unloading cylinder 340 and is used to weigh the receiving cup and the medicinal powder inside it; the conveyor line 800 is arranged in parallel with the weighing mechanism 500 and is used to transport the receiving cup with qualified medicinal powder to the next process structure.

[0030] In some embodiments of this application, the dispensing mechanism 600 includes a waste cup 640 and a second gripper 610. The waste cup 640 is positioned at a specific location between the conveyor line 800 and the weighing mechanism 500 to collect powdered medicine that does not meet the weight requirements. The second gripper 610 is positioned above the waste cup 640 and is responsible for pouring the powdered medicine that does not meet the weight requirements into the waste cup 640.

[0031] In some embodiments of this application, such as Figure 5 , Figure 6 As shown, the material handling mechanism 300 includes a mounting plate 320, a first arm 321, a second arm 322, and a rolling element 323. The mounting plate 320 is slidably mounted on the first slide rail 110. The first arm 321 is rotatably mounted through the mounting plate 320 about its own axis. The material handling rod 310 is connected to the first end of the first arm 321 along its length, and the second arm 322 is connected to the second end of the first arm 321 along its length. The first arm 321 and the second arm 322 are arranged perpendicularly. The rolling element 323 is rotatably mounted at the end of the second arm 322 about its own axis. When the guide mechanism 400 is in the first position, the rolling element 323 is connected to the guide mechanism 400; when the guide mechanism 400 is in the second position, the rolling element 323 is disengaged from the guide mechanism 400.

[0032] In some embodiments of this application, reference is made to Figure 6 As shown, the guiding mechanism 400 is provided with a guide groove 410. When the guiding mechanism 400 is in the first position, the rolling element 323 on the picking mechanism 300 is embedded in the guide groove 410. During the process of the picking mechanism 300 moving from the initial position to the material bin 200, the rolling element 323 slides along the guide groove 410.

[0033] Reference Figure 6As shown, the guide groove 410 includes an arc segment 411. When the rolling element 323 slides along the arc segment 411, it will drive the first arm 321 to rotate around its own axis through the second arm 322, thereby ultimately causing the picking rod 310 to deflect. Specifically, when the rolling element 323 slides upward along the arc segment 411, it will drive the picking rod 310 to deflect downward, and the picking rod 310 will extend into the material bin 200 to pick up material; conversely, when the rolling element 323 slides downward along the arc segment 411, it will drive the picking rod 310 to deflect upward, so that the picking rod 310 returns to its initial horizontal state, thereby completing one picking action.

[0034] Furthermore, the arc segment 411 is located in the middle part of the guide groove 410, and both ends of the guide groove 410 are straight segments, and the straight segments at both ends are at the same height. Thus, when the rolling element 323 is located in the straight segment at either end of the guide groove 410, the picking rod 310 is stably kept in a horizontal state.

[0035] As described above, when the picking mechanism 300 carries the powder away from the material bin 200 and returns to its initial position, the guide mechanism 400 is in the second position, and the rolling element 323 disengages from the guide groove 410. At this time, the guide groove 410 can no longer affect the picking rod 310. To ensure that the picking rod 310 does not deflect unexpectedly during the movement of the picking mechanism 300 towards its initial position, that is, to ensure that the picking rod 310 always remains horizontal to stably convey the powder, the picking mechanism 300 of this application is further provided with a reset structure 324. The reset structure 324 is connected to the first arm 321. The reset structure 324 is used to drive the first arm 321 to rotate axially when needed, thereby driving the picking rod 310 to deflect precisely back to the horizontal position.

[0036] In some specific embodiments of this application, the reset structure 324 may adopt, for example... Figure 5 The torsion spring shown is fitted onto the first arm 321, with its two ends resting against the mounting plate 320. The torsion spring is precisely preloaded and calibrated to ensure that regardless of whether the material-retrieving rod 310 deflects upwards or downwards during the material-retrieving action, it provides a stable restoring torque, reliably driving the first arm 321 to rotate and ultimately accurately returning the material-retrieving rod 310 to its initial horizontal position.

[0037] It is worth noting that the specific implementation of the reset structure 324 is not limited to a torsion spring. It can also be designed as other mechanical or elastic structures with similar reset functions, depending on the spatial layout, load requirements, or cost considerations in the actual application scenario.

[0038] In some embodiments of this application, in order to achieve precise control over the amount of material picked up by the picking rod 310 each time and to ensure the standardization and consistency of the picking action, the sensitive powder picking device also includes a scraper structure 220, which is arranged on the path of the picking mechanism 300 returning from the material bin 200 to the initial position. (Refer to...) Figure 3 , Figure 4 As shown, the feeding rod 310 is provided with a concave receiving groove 311 specifically for holding the powder. The scraper structure 220 is configured such that when the feeding mechanism 300 completes feeding and moves away from the material bin 200 to the initial position, the scraper will clean up any excess or scattered powder outside the receiving groove 311 on the feeding rod 310 in a timely manner. This ensures that the amount of powder obtained by the feeding rod 310 in each feeding action is strictly limited to the capacity of a single receiving groove 311, so as to complete accurate quantitative feeding, avoid over- or under-feeding, and improve the accuracy and reliability of the entire feeding process.

[0039] In some specific embodiments of this application, reference is made to Figure 4 As shown, the material bin 200 defines a dedicated receiving cavity 210 for storing medicine powder. At the same time, a scraper structure 220 is installed on the material bin 200 and extends into the receiving cavity 210. This ensures that when the picking rod 310 performs a picking operation, any medicine powder scraped off the picking rod 310 by the scraper structure 220 can be guided back into the receiving cavity 210. This prevents the risk that medicine powder may cause by scattering outside the equipment and reduces the ineffective waste of medicine powder, making the material utilization more efficient.

[0040] In some embodiments of this application, the unloading cylinder 340 is disposed on the sliding path of the picking mechanism 300, and when the picking mechanism 300 is in the initial position, the picking rod 310 is exactly above the unloading cylinder 340, combined with Figure 2 and Figure 3 This allows for a clearer understanding. The main function of the unloading cylinder 340 is to receive the powder transferred from the picking rod 310. The picking rod 310 first obtains a fixed amount of powder from the receiving cavity 210 of the material bin 200, then moves to the initial position and unloads the powder into the unloading cylinder 340 for subsequent transfer or processing steps. Since the picking mechanism 300 completes the unloading action at the initial position, it only needs to have two clearly defined positions: a starting point and an ending point. No pauses or waiting are required during the entire process, simplifying the motion logic of the picking mechanism 300, greatly reducing the mechanical and control complexity of the entire equipment system, and helping to reduce manufacturing and maintenance costs. Furthermore, the fact that the picking mechanism 300 completes the unloading action at the initial position ensures that its position is highly consistent each time it performs an unloading operation, thus guaranteeing the reliability of the unloading process.

[0041] In some embodiments of this application, the unloading cylinder 340 is designed to be liftable and installed on the working platform 100. Specifically, when the material handling mechanism 300 slides toward the material bin 200, the unloading cylinder 340 descends, lowering its top below the plane of the working platform 100 to avoid obstructing or interfering with the horizontal movement path of the material handling mechanism 300 and to ensure smooth movement of the material handling mechanism 300. Conversely, when the material handling mechanism 300 completes material handling and returns to its initial position, and the material handling rod 310 pours powder into the unloading cylinder 340, the unloading cylinder 340 is controlled to rise to a preset height, bringing the open end of the unloading cylinder 340 close to the material handling rod 310 above it, and the material handling rod 310 then performs the unloading action. As the unloading cylinder 340 rises to a position close to the receiving rod 310, the distance between the unloading cylinder 340 and the receiving rod 310 decreases. During the process of the powder falling into the unloading cylinder 340 under gravity, the probability of powder scattering or being lost due to height difference and air turbulence is significantly reduced. This further improves the accuracy of the weight of powder transferred in a single receiving operation and reduces weight errors. The preset height position typically refers to the highest point or optimal receiving position that the unloading cylinder 340 can reach during its upward stroke.

[0042] In some embodiments of this application, reference is made to Figure 3 As shown, the picking rod 310 is connected to a rotating structure 330. The picking rod 310 is installed at the output end of the rotating structure 330, and the rotating structure 330 drives the picking rod 310 to rotate around its axis. Specifically, when the receiving groove 311 of the picking rod 310, carrying the powder, moves above the unloading cylinder 340, the rotating structure 330 drives the picking rod 310 to rotate 180 degrees around its own axis to pour the powder in the receiving groove 311 into the unloading cylinder 340 below. The rotating structure 330 is connected to the first arm 321. The rotating structure 330 can be a rotary cylinder, rotary hydraulic cylinder, rotary motor, or other rotary drive devices; this embodiment does not limit the type of rotary drive.

[0043] In some embodiments of this application, reference is made to Figure 2 , Figure 5As shown, the material handling mechanism 300 also includes a first sleeve 350, which is movably and vertically mounted on the working platform 100 and positioned above the unloading cylinder 340. When the material handling rod 310 pours material into the unloading cylinder 340, the first sleeve 350 moves downward, so that its cylinder body fits over the outside of the material handling rod 310, and its bottom portion extends into the unloading cylinder 340. Specifically, the first sleeve 350 is preferably a cylindrical structure with an open bottom, and an opening groove is provided on the side wall of the first sleeve 350 for the material handling rod 310 to be inserted laterally. By using the design of the first sleeve 350 fitting over the material handling rod 310 and partially extending into the unloading cylinder 340 during material pouring, a relatively closed transition channel can be formed, thereby greatly avoiding the scattering and escape of the powder during the transfer process, and further improving the accuracy and reliability of the powder handling process.

[0044] In some embodiments of this application, reference is made to Figure 5 As shown, a first striking structure 351 is also installed on the first sleeve 350. The first striking structure 351 is configured to strike the rod body or a specific part of the picking rod 310 in a timely manner during the action of the picking rod 310 pouring the powder into the unloading cylinder 340. The vibration ensures that the powder adhering to the inner wall of the receiving groove 311 of the picking rod 310 can be completely shaken off and poured into the unloading cylinder 340, so as to avoid inaccurate picking due to residue.

[0045] Similarly, in some embodiments of this application, reference is made to Figure 7 , Figure 8 As shown, a second striking structure 341 is also installed on the working platform 100. The second striking structure 341 is configured to strike the outer wall of the unloading cylinder 340 during the process of pouring the powder inside the unloading cylinder 340 into the receiving cup below. The resulting vibration causes the powder particles adhering to the inner wall of the unloading cylinder 340 to fall off, ensuring that the powder inside the unloading cylinder 340 is completely emptied and poured into the receiving cup, guaranteeing the integrity of the powder weight transferred each time. The second striking structure 341 is fixedly installed in the lower area of ​​the working platform 100 for striking the outer wall of the unloading cylinder 340. After the powder is poured from the receiving rod 310 into the unloading cylinder 340, a receiving cup is usually placed directly below the unloading cylinder 340 to finally receive the powder. Since the unloading cylinder 340 can be raised and lowered relative to the working platform 100, and the lower end of the unloading cylinder 340 is designed to pass through the working platform 100 and extend to the space below the working platform 100, the second striking structure 341 is set below the working platform 100 to avoid the second striking structure 341 obstructing or interfering with the horizontal movement of the receiving rod 310 above the working platform 100.

[0046] The first striking structure 351 ensures that the powder in the receiving groove 311 of the picking rod 310 is completely shaken off and transferred to the unloading cylinder 340 without any residue. The second striking structure 341 ensures that all the powder received in the unloading cylinder 340 is completely shaken off into the receiving cup below, also avoiding residue on the inner wall of the unloading cylinder 340. The two striking structures work together to minimize material loss during the picking and transfer process, thereby significantly improving the accuracy of the entire process from picking to final receiving. To simplify equipment management and maintenance, the first striking structure 351 and the second striking structure 341 preferably use striking equipment of the same model and specifications, such as electromagnetic striking devices or pneumatic striking hammers, which helps to reduce equipment procurement costs, spare parts inventory costs, and long-term operation and maintenance costs.

[0047] In some embodiments of this application, reference is made to Figure 1 As shown, the transfer mechanism 700 includes a first gripper 710 for directly clamping the receiving cup, a first adjustment structure 720 for driving the first gripper 710 to move horizontally, and a second adjustment structure 730 for driving the first gripper 710 to move vertically. The first adjustment structure 720 is responsible for driving the first gripper 710 to move in the horizontal plane, thereby realizing the switching of the gripper-driven receiving cup between the three stations of the weighing mechanism 500, the pouring mechanism 600, and the conveyor line 800; the second adjustment structure 730 is responsible for driving the first gripper 710 to move vertically. The specific mechanical configuration of the first adjustment structure 720 and the second adjustment structure 730 is not limited in this embodiment. After the first gripper 710 holds the receiving cup, the second adjustment structure 730 can drive the receiving cup to rise and fall between the outlet of the unloading cylinder 340 and the weighing pan of the weighing mechanism 500, so as to ensure that the receiving cup can rise to a position very close to the outlet of the unloading cylinder 340 when receiving material, thereby minimizing the flying and loss of powder caused by the drop difference during the process of the powder falling from the unloading cylinder 340 into the receiving cup, and further improving the accuracy of the transfer of powder weight.

[0048] In some embodiments of this application, reference is made to Figure 1As shown, the transfer mechanism 700 further includes a third adjustment structure 740, which is mounted on the first adjustment structure 720. A second adjustment structure 730 is mounted on the third adjustment structure 740, and the first gripper 710 is connected to the second adjustment structure 730. The third adjustment structure 740 can drive the second adjustment structure 730 to move vertically, thereby driving the first gripper 710 to move vertically. After the second adjustment structure 730 drives the first gripper 710 to pick up the receiving cup and rise below the unloading cylinder 340 to complete the receiving, the second adjustment structure 730 will first drive the first gripper 710 to descend to the end of its own stroke; then, the third adjustment structure 740 will start again, driving the entire second adjustment structure 730, together with the first gripper 710 and the receiving cup, to descend further, thereby placing the receiving cup stably on the weighing pan of the weighing mechanism 500. The two-stage descent achieved by the second adjustment structure 730 and the third adjustment structure 740 makes the receiving cup descend more smoothly and slowly, effectively avoiding the problem of the powder in the receiving cup being spilled due to sudden descent or shaking.

[0049] Correspondingly, when the receiving cup is placed on the conveyor line 800, a two-stage descent can be used to make the descent smoother and slower. Similarly, when the transfer mechanism picks up the receiving cup from the conveyor line 800 or from the weighing mechanism 500, a two-stage ascent can be achieved through the second adjustment structure 730 and the third adjustment structure 740 to ensure that the receiving cup rises more smoothly and slowly.

[0050] In some embodiments of this application, reference is made to Figure 7 , Figure 8 As shown, the discharging mechanism 600 includes a second gripper 610 and a rotating component 620. The second gripper 610 receives the receiving cup containing substandard powder from the first gripper 710 of the transfer mechanism 700. Then, the rotating component 620 drives the second gripper 610 to flip, thereby pouring the powder from the receiving cup into the waste cup 640 below. After the collected powder in the waste cup 640 reaches a certain weight or volume, it can be recycled manually or by connecting to an automatic recycling system.

[0051] In some embodiments of this application, in order to minimize the pollution of the environment and equipment caused by powder splashing when discharging substandard powder, the discharging mechanism 600 is also provided with a second sleeve 630. (See also...) Figure 3 , Figure 8As shown, the second sleeve 630 is movably and vertically mounted on the work platform 100 and positioned above the second gripper 610. When the second gripper 610 clamps the receiving cup and pours the powder into the waste cup 640, the second sleeve 630 descends to cover the second gripper 610, thereby suppressing the spread of dust generated during the pouring process. When the second sleeve 630 descends to a set height, the bottom portion of the second sleeve 630 extends into the waste cup 640.

[0052] In some embodiments of this application, reference is made to Figure 8 As shown, it is further preferred that the waste cup 640 or the second gripper 610 can be movable and raised. When the second gripper 610 pours material into the waste cup 640, the waste cup 640 can rise and the second sleeve 630 can fall, or the second gripper 610 can fall and the second sleeve 630 can fall, so as to further reduce the probability of the powder splashing out during the pouring process.

[0053] In some embodiments of this application, to avoid unnecessary spillage and waste of the powder during transfer and pouring, and to ensure highly accurate dosage of the powder each time, the pouring mechanism 600 designed in this application is also provided with a third tapping structure 631, as shown in the reference. Figure 3 , Figure 8 As shown, the third striking structure 631 is preferably installed on the second sleeve 630. When the second gripper 610 performs a tilting action, pouring the held powder into the waste cup 640, and after the second sleeve 630 has completed the operation of descending to the set height, the third striking structure 631 will be activated and strike the receiving cup currently held by the second gripper 610. The vibration will cause the powder adhering to the cup wall to completely fall off, further ensuring the integrity and accuracy of the powder transfer.

[0054] In some embodiments of this application, reference is made to Figure 1 , Figure 2 As shown, the work platform 100 is equipped with multiple material handling mechanisms 300, which are spaced apart along the conveying direction of the conveyor line 800. Correspondingly, the weighing mechanism 500, waste cup 640, pouring mechanism 600, and transfer mechanism 700 are all configured as multiple material handling mechanisms 300 to improve the compactness of the weighing device of this application, achieve efficient space utilization, and significantly improve the overall process efficiency and processing capacity through multi-station parallel operation.

[0055] In summary, the sensitive powder weighing and dispensing device of this application, through the coordinated operation of the dispensing mechanism 300 and the guiding mechanism 400, achieves automatic dispensing of the dispensing rod 310 within the material bin 200, reducing manual intervention and improving dispensing safety. The guiding mechanism 400 forces the dispensing rod 310 downwards and extends it into the material bin 200 to dispense the powder, enabling the dispensing rod 310 to complete the dispensing by scooping, reducing the risk of collision, compression, and friction between the dispensing rod 310 and the powder, further enhancing equipment safety. After the dispensing rod 310 pours the powder into the unloading cylinder 340, the transfer mechanism 700 clamps the receiving cup to collect the powder in the unloading cylinder 340 and automatically transfers it to the weighing mechanism 500. Subsequently, powder with acceptable weight is sent to the conveyor line 800, while unacceptable powder is sent to the unloading mechanism 600 for recycling. This device achieves automatic dispensing, weighing, and screening of sensitive powder, with strong operational standardization, significantly improving work efficiency and reducing operational risks.
