Description

Technical Field

[0001] This invention relates to the field of pharmaceutical weighing and testing technology, and in particular to a material turning and weighing device. Background Technology

[0002] In existing technologies, product weighing and sorting are generally two separate processes. Drugs are placed statically into the weighing equipment for weighing, and then unqualified products are sorted out. Weighing and sorting are thus separated into two processes, with most products undergoing re-inspection via random sampling after packaging. Another approach is a dynamic checkweighing and sorting machine that integrates weighing and sorting into a single structure. However, existing technologies, where weighing and sorting are separate processes and each product is inspected individually, result in a large workload, high labor intensity, and low production efficiency. The random sampling method for weighing is also inefficient, prone to missed inspections, and has a low pass rate. Furthermore, existing dynamic checkweighing and sorting machines are insufficient for meeting the high weight accuracy requirements of drugs, exhibiting low checkweighing accuracy and failing to guarantee the overall quality of the drugs.

[0003] According to patent document CN212158777U, a pharmaceutical weighing platform includes a platform and a weighing scale. The platform is placed at the output end of a pharmaceutical conveyor belt. A recessed groove is formed on the platform surface, and the weighing scale is placed within the groove. The surfaces of the pharmaceutical conveyor belt, the weighing scale, and the platform are all on the same plane. An elastic locking device is installed on the platform, containing an elastic element. Under the elastic force of the elastic element, the elastic locking device is kept in a state that prevents the weighing scale from disengaging from the groove. An auxiliary release rod is installed at the bottom of the platform. The auxiliary release rod interacts with the elastic locking device; driving the auxiliary release rod enables the elastic locking device to engage. After the device releases the weighing scale, it pushes the weighing scale out of the placement slot. In use, after the platform and weighing scale are placed at the output end of the conveyor belt, the medicine automatically moves to the surface of the weighing scale under the action of inertia after the conveyor belt outputs the medicine, thereby realizing the weighing. This avoids the cumbersome operation of manually placing the medicine on the weighing scale, improves production efficiency, and reduces labor costs. Regarding the above technical solution, although the medicine is transported through the conveyor belt, the tilt angle of the conveyor belt and the landing position of the medicine cannot be adjusted during use, and the interval between medicines cannot be adjusted during the transport of medicines, which is inconvenient during use.

[0015] Optionally, a vertical plate is welded onto the base, and a buffer plate is fixed to the top of the vertical plate. The buffer plate includes a qualified discharge plate and an unqualified discharge plate, which are respectively distributed on one side of the arc-shaped base.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: 1. This invention features adjustable spacing between medicines, thereby controlling the speed and position of medicine descent. It solves the problem in the prior art that medicines cannot be weighed one by one on the weighing equipment. By installing baffles between the positioning plates, the baffles are selectively installed according to the length of the medicines and the required spacing. The displacement mechanism pushes one end of the transmission seat to move. When the transmission seat is moved, the overall tilt angle of the transmission belt is changed. The adjustment of the tilt angle avoids damage caused by medicines falling too high. 2. This invention has the ability to change the position of the medicine drop point, solving the problem that medicines of different sizes cannot be evenly spread on the weighing equipment. The displacement mechanism changes the position of one end of the transmission seat by moving the fixed block. After the transmission belt drops the medicine onto the arc-shaped seat, the displacement mechanism drives one end of the transmission seat to move horizontally. The horizontal displacement of one end of the transmission seat changes the tilt angle. After the tilt angle of the transmission belt is adjusted, the medicine can be slowly spread on the arc-shaped seat for weighing, thereby avoiding the impact of medicines that are too large falling out of the arc-shaped seat. 3. This invention has the effect of buffering medicines, solving the problem of damage caused by medicines falling from a height to the weighing point. The curved plate is movably installed inside the curved groove. After the medicine falls on the curved plate, the curved plate rotates through the support column and torsion spring. The rotation of the curved plate achieves the initial buffering of the medicine. In addition, the curved seat as a whole achieves secondary buffering and shock absorption through the damper and tension mechanism. 4. This invention has the effect of assisting the outward discharge of medicines, solving the problem of slow outward discharge of medicines when tilted in existing products. By rotating the arc-shaped seat, the arc-shaped plate loses its center of gravity as the medicine rotates. The torsion spring moves the arc-shaped plate outward through the support column. One end of the arc-shaped plate pushes the medicine off the reinforcing plate to fall outward more quickly, which is beneficial for the subsequent sorting and discharge of medicines.

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 10As shown, a material turning and weighing device includes: a base 1, with a vertical plate 2 welded to the top of the base 1, a mounting seat 3 welded to the side of the vertical plate 2, a mounting plate 4 fixed to the top of the mounting seat 3, a weighing sensor 5 fixedly mounted on the top of the mounting plate 4, and a support seat 10 welded to the base 1; a transmission assembly 11, including a transmission seat 22, with a servo motor 27 fixedly mounted on the transmission seat 22, an active roller mounted on the servo motor 27, the active roller rotatably mounted between the transmission seats 22, a transmission belt 26 rotatably mounted on the active roller, and a driven roller rotatably mounted at the other end of the transmission belt 26, the driven roller rotatably mounted at one end of the transmission seat 22; and a weighing assembly 28, including a movable seat 37, the movable seat 37 rotatably mounted on the support seat 10, an arc-shaped seat 38 movably mounted on the movable seat 37, and a rotating seat 9 movably mounted at the other end of the arc-shaped seat 38. An arc-shaped groove 48 is formed on the 38, and an arc-shaped plate 39 is movably installed inside the arc-shaped groove 48. The arc-shaped plate 39 rotates inside the arc-shaped groove 48 via a support column 41 and a torsion spring 42. When medicine falls onto the arc-shaped plate 39, a reinforcing plate 40 blocks and limits one end of the arc-shaped plate 39. The presence of the reinforcing plate 40 effectively prevents one end of the arc-shaped plate 39 from tilting upwards. In addition, it provides initial buffer protection after the medicine falls onto the arc-shaped plate 39, preventing the medicine from colliding with the reinforcing plate 40 and falling outwards. Furthermore, the fall of the medicine causes the arc-shaped seat 38 to shake inside the mounting groove via a positioning block 44 and a damper 45. The damper 45 and the tension mechanism 46 work together to achieve secondary buffer protection. The tension mechanism 46 is a tension spring. When the tension spring is compressed, it generates a rebound force. The presence of the damper 45 causes the tension mechanism 46 to push the positioning block 44 back to its original position.

[0022] Please see Figures 6 to 8A reinforcing plate 40 is movably installed on the top between the arc-shaped plates 39. The reinforcing plate 40 is welded and fixed to the arc-shaped seat 38. Support columns 41 are fixed at both ends of the arc-shaped plates 39. Torsion springs 42 are fixed to the sides of the support columns 41. The support columns 41 are rotatably installed on the inner wall of the arc-shaped groove 48 through the torsion springs 42. Positioning columns 43 are fixed at both ends of the arc-shaped seat 38. Positioning blocks 44 are fixed at one end of the positioning columns 43. A damper 45 is fixed at the bottom of the positioning blocks 44. A tension mechanism 46 is installed on the side of the damper 45. A mounting block 47 is fixed at one end of the damper 45. Mounting slots are opened on both the movable seat 37 and the rotating seat 9. The mounting block 47 is fixedly installed inside the mounting slot. A motor seat 6 is welded to the side of the upright plate 2. A drive motor 7 is fixedly installed on the motor seat 6. A rotating rod is installed on the drive motor 7. A coupling 29 is installed at one end of the rotating rod. A positioning disk 30 is fixed at one end, and an output shaft 34 is fixed on the positioning disk 30. In use, the drive motor 7 drives the output shaft 34 on the coupling 29 to rotate. The output shaft 34 and the positioning disk 30 rotate together. The rotation of the positioning disk 30 cooperates with the proximity sensor 33 to perform subsequent homing. A receiving end is fixed on the positioning disk 30. When the receiving end is aligned with the proximity sensor 33, the position status of the arc-shaped seat 38 can be quickly determined, thereby judging whether the arc-shaped seat 38 has reached the homing state. After the arc-shaped seat 38 reaches the homing state, the transmission component 11 is activated to transfer the medicine. During drug transfer, the position and spacing of the baffles are selected according to the size of the drugs. The baffles slide between the positioning plates 25. After installation, limit beads are fixed to the sides of the baffles, and these limit beads are movably installed inside the fixing holes 36 for fixation. Later, external pulling force is used to quickly remove the baffles from the positioning plates 25, activating the displacement mechanism 19 to push the fixing block 20 horizontally. The horizontal movement of the fixing block 20 drives one end of the transmission seat 22 outward via the rotating column 21. After the external movement, the slider 14 on the transmission seat 22 descends downward inside the slide groove 13. As the slider 14 descends, it compresses the support mechanism 17. The support mechanism 17 is a support spring. After being compressed, the support spring generates a rebound force, which pushes the slider 14 to move upward and return to its original position. When the slider 14 moves downward, the limit block 16 moves towards the servo motor 27 inside the limit groove 23. As one end of the transmission seat 22 controls the position and height of its other end in conjunction with the arc-shaped seat 38, the medicine is buffered and protected to avoid damage caused by the medicine falling from a height.

[0023] Please see Figures 3 to 5A limit seat 31 is installed on the output shaft 34. The limit seat 31 is fixedly installed on the top of the upright plate 2. A fixing frame 32 is fixed on the top of the upright plate 2. A proximity sensor 33 is fixedly installed on the fixing frame 32. A rotating shaft 35 is fixed to one end of the output shaft 34. One end of the rotating shaft 35 is welded to one side of the rotating seat 9. A limit groove 23 is opened on the side of the transmission seat 22. A reset mechanism 24 is fixed inside the limit groove 23. A limit block 16 is fixed to one end of the reset mechanism 24. A rotating shaft 15 is rotatably installed on the side of the limit block 16. A slider 14 is rotatably installed on one end of the rotating shaft 15. An opening 12 is formed on the support base 10, and a groove 13 is formed on the inner wall of the opening 12. A slider 14 is movably installed inside the groove 13. A support mechanism 17 is fixed inside the groove 13, and one end of the support mechanism 17 is fixedly installed on the slider 14. In use, the reset mechanism 24 is a reset spring. The reset spring deforms after being stretched. The deformed reset mechanism 24 drives the limit block 16 to return to its original position. After the fixed block 20 drives the transmission base 22 to tilt, the transmission belt 26 moves the medicine towards the arc-shaped base 38 as the servo motor 27 rotates. The medicine can be placed at the baffle, which blocks the medicine. After the medicine falls from the baffle, the transmission belt 26 stops rotating. After the medicine falls onto the arc-shaped base 38, it falls onto the arc-shaped plate 39. One end of the arc-shaped plate 39 retracts into the arc-shaped groove 48. When one end of the arc plate 39 rotates, the rotation of the support column 41 completes the rotational deformation of the torsion spring 42. The movement of the arc plate 39 provides initial buffering for the medicine. After the medicine falls onto the arc seat 38, it is weighed by the weighing sensor 5. When the weight reaches the standard, the drive motor 7 is started to drive the arc seat 38 to rotate to the left. As the arc seat 38 rotates to the left, the medicine falls from the qualified discharge plate on one side to the other side for collection. When the weight of the medicine does not meet the standard, the arc seat 38 rotates to the right, and the medicine on the arc seat 38 is discharged outward from the unqualified discharge plate. With the rotation of the arc seat 38, the arc plate 39 loses its center of gravity as the medicine rotates. The torsion spring 42 pushes the arc plate 39 outward through the support column 41. One end of the arc plate 39 pushes the medicine to fall outward from the reinforcing plate 40 at an accelerated speed, which is beneficial for the subsequent sorting and discharge of the medicine.

[0024] Please see Figures 3 to 5A fixing groove 18 is formed on the inner wall of the opening 12. A fixing block 20 is movably installed inside the fixing groove 18. A displacement mechanism 19 is installed on the fixing block 20 and is fixedly installed on the support base 10. A rotating column 21 is rotatably installed on the fixing block 20, and one end of the rotating column 21 is fixedly installed on one end of the transmission base 22. A positioning plate 25 is fixed on the transmission belt 26. A baffle is movably installed between the positioning plates 25. Fixing holes 36 are formed on both the baffle and the positioning plate 25. Anti-slip grooves are formed on the surfaces of the driving roller and the driven roller. A friction plate is fixed on the inner wall of the transmission belt 26 and cooperates with the anti-slip groove. A vertical plate is welded onto the base 1, and a buffer plate 8 is fixed to the top of the vertical plate. The buffer plate 8 includes a qualified discharge plate and an unqualified discharge plate, which are respectively distributed on one side of the arc-shaped seat 38. When in use, if it is not necessary to use the baffle to limit and fix the medicine, the fixing bolts are removed from the inside of the fixing hole 36, and the baffle is removed from between the positioning plates 25. The positioning plate 25 is a hard rubber plate. The rubber plate will deform when it moves to the active roller and the driven roller. After deformation, the positioning plate 25 is stretched. After the positioning plate 25 is stretched, the connection of the baffle will not be damaged. Therefore, the conveyor belt 26 can be rotated during the use of the positioning plate 25 and the baffle. When the length of the medicine is long, the displacement mechanism 19 is first activated to push the fixed block 20 to move in the direction of the drive motor 7. As the fixed block 20 moves, it drives the conveyor seat 22 through the rotating column 21. As one end moves, the overall tilt angle of the transmission seat 22 decreases, making it easier to transport large medicines. Large medicines are less likely to fall off the transmission belt 26 during transport. When one end of the medicine falls onto the arc plate 39 along with the transmission belt 26, the displacement mechanism 19 retracts, causing the fixed block 20 to move. The fixed block 20 moves back to its original position towards the support seat 10. As the fixed block 20 returns to its original position, the support mechanism 17 pushes the slider 14 upward, and the reset mechanism 24 pulls the limit block 16 downward. Through the movement of the slider 14 and the limit block 16, the top of the transmission seat 22 tilts upward, increasing the tilt angle. One end of the transmission belt 26 gently places the medicine inside the arc plate 39 for weighing, thus preventing large medicines from falling onto the arc seat 38 and ensuring stable weighing of the medicines later.

[0025] Working principle: During use, the distance between the baffles is selected according to the size of the medicine. The baffles are installed on the positioning plates 25. The medicine is manually placed on one side of the baffle, and the baffle limits the movement of the medicine. During installation, the baffles slide between the positioning plates 25. After the baffles are installed between the positioning plates 25, they are fixed to the positioning plates 25 by external fixing bolts. The displacement mechanism 19 is activated to push the fixing block 20 to move horizontally. The horizontal movement of the fixing block 20 drives one end of the transmission seat 22 to move outward through the rotating column 21. After one end of the transmission seat 22 moves outward, the slider 14 on the transmission seat 22 descends downward inside the slide groove 13. As the slide descends, it compresses the support mechanism 17, which is a support spring. The spring, when compressed, generates a rebound force, which pushes the slider 14 upwards to return to its original position. When the slider 14 moves downwards, the limiting block 16 moves towards the servo motor 27 within the limiting groove 23. As one end of the transmission seat 22 controls the position and height of its engagement with the arc-shaped seat 38, the servo motor 27 is activated, driving the active roller and transmission belt 26 to rotate. As the transmission belt 26 rotates, it pushes the medicine through the baffle. When the medicine reaches one end of the transmission belt 26, it falls into the arc-shaped seat 38. After the medicine falls from the front baffle, the transmission belt 26... After the rotation stops, the medicine falls onto the arc-shaped seat 38 and then onto the arc-shaped plate 39. One end of the arc-shaped plate 39 retracts into the arc-shaped groove 48. When one end of the arc-shaped plate 39 rotates, the support column 41 rotates, causing the torsion spring 42 to deform. The movement of the arc-shaped plate 39 provides initial cushioning for the medicine. The presence of the reinforcing plate 40 effectively prevents the arc-shaped plate 39 from tilting upwards. Furthermore, after the medicine falls onto the arc-shaped plate 39, it provides initial cushioning protection, preventing the medicine from colliding with the reinforcing plate 40 and falling outwards. Additionally, the falling medicine causes the arc-shaped seat 38 to be positioned within the mounting groove via the positioning block 44 and the damper 45. The damper 45 and the tension mechanism 46 work together to achieve secondary buffer protection. The tension mechanism 46 is a tension spring. After being compressed, the tension spring generates a rebound force. The presence of the damper 45 causes the tension mechanism 46 to push the positioning block 44 to slowly return to its original position. After the medicine falls onto the arc-shaped seat 38, it is weighed by the weighing sensor 5. When the weight reaches the standard, the drive motor 7 is started to drive the arc-shaped seat 38 to rotate to the left. As the arc-shaped seat 38 rotates to the left, the medicine falls from the qualified discharge plate on one side to the side for collection. When the weight of the medicine does not meet the standard, the arc-shaped seat 38 rotates to the right, and the medicine on the arc-shaped seat 38 is discharged from the unqualified discharge plate. When not using a baffle to limit and fix the medicine, the fixing bolts are removed from the inside of the fixing hole 36, and the baffle is removed from between the positioning plates 25. The positioning plates 25 are made of rigid rubber plates. The rubber plates deform when they move to the drive roller and driven roller, and the deformed positioning plates 25 are stretched. After the positioning plates 25 are stretched, the connection between the baffles will not be damaged. Therefore, the conveyor belt 26 can be rotated during the use of the positioning plates 25 and the baffles. When the length of the medicine is long, the displacement mechanism 19 is first activated to push the fixing block 20 to move towards the drive motor 7. As the fixing block 20 moves, it drives one end of the transmission seat 22 to move through the rotating column 21. After the transmission seat 22 moves, the overall tilt angle of the transmission seat 22 becomes smaller, and the conveyor belt 26 tilts. The smaller angle facilitates the transport of large medicines, making it less likely for them to fall off the conveyor belt 26. When one end of the medicine falls onto the arc plate 39 along with the conveyor belt 26, the displacement mechanism 19 retracts, causing the fixed block 20 to move. The fixed block 20 moves back to its original position towards the support seat 10. As the fixed block 20 returns to its original position, the support mechanism 17 pushes the slider 14 upward, and the reset mechanism 24 pulls the limit block 16 downward. Through the movement of the slider 14 and the limit block 16, the top of the conveyor seat 22 tilts upward. After the conveyor seat 22 tilts upward, the angle of inclination increases, and one end of the conveyor belt 26 gently places the medicine inside the arc plate 39 for weighing. This avoids large medicines falling onto the arc seat 38, ensuring stable weighing of the medicines in the later stages.
