Description

Technical Field

[0002] In the production process of traditional Chinese medicine tablets, an efficient and accurate conveying link is crucial. At the same time, in order to meet the subsequent production requirements of bottling or canning traditional Chinese medicine tablets, most conveying lines need to quantitatively convey traditional Chinese medicine tablets.

[0003] Most traditional quantitative conveying methods for traditional Chinese medicine tablets rely on manual operation or simple mechanical structures. Manual quantitative conveying has extremely low efficiency and is greatly affected by human factors. It is difficult to ensure that the number of tablets conveyed each time is accurately the same, and dosage deviation is likely to occur, seriously affecting the stability and uniformity of the quality of the medicine. Some existing simple mechanical quantitative conveying devices, such as equipment using gravity feeding in combination with a fixed-volume hopper, although improve the conveying efficiency to a certain extent, have extremely poor adaptability to traditional Chinese medicine tablets of different shapes, sizes, and weights, and often experience situations such as material jamming and leakage, and cannot achieve accurate quantitative conveying, thus unable to meet the strict requirements of modern pharmaceutical production for efficient and accurate quantitative conveying. Therefore, there is an urgent need for an automatic conveying line for traditional Chinese medicine tablets to solve the above problems. Summary of the Invention

[0020] Advantages of the present invention:

[0021] For the automatic conveying line of traditional Chinese medicine tablets provided by the present invention, when the tablet body is being conveyed, since the included angle between the circular frame and the horizontal direction is 15°, the tablet bodies poured into the circular frame can be concentrated and stacked below the inside of the circular frame. Subsequently, the operator starts the motor, and the motor can drive the second rotating column and the first helical gear to rotate together. Through the meshing between the first helical gear and the second helical gear, the first rotating column can be driven to rotate together, and the feeding tray located in the circular frame is fixedly connected to the first rotating column. When the first rotating column rotates, the feeding tray can be driven to rotate together. At this time, when the feeding holes formed in the feeding tray rotate to the lower part of the stacked tablet bodies, the tablet bodies will fall into the inside of the feeding holes due to gravity, thus realizing the automatic quantitative conveying of the tablet bodies, meeting the usage requirements of people. And during the rotation of the feeding tray, a small amount of tablet bodies staying on the top of the feeding tray can be scraped off by the baffle, and the scraped tablet bodies will fall back to the stacking place again due to gravity to carry out the quantitative conveying work of the next cycle. And while the first rotating column is rotating, the semi-cylindrical block arranged on its outer wall will generate a certain centrifugal force. Through the combined action of this centrifugal force and the first spring in the vibration assembly, the feeding tray can be made to shake left and right while doing circular motion, so that the stacked tablet bodies can be more easily filled into the feeding holes, avoiding the situation of missing filling and ensuring the accuracy of the entire quantitative conveying process.

[0022] An automatic conveying line for traditional Chinese medicine tablets provided by the present invention, through the provided detection component, when the feeding hole on the feeding tray rotates to the blanking chute, the tablets in the feeding hole will immediately fall into the guiding frame, and then fall into the conveyor belt through the guiding frame for subsequent conveying work. And during the process of the tablet body falling from the blanking chute, the surface of the tablet body can be imaged by a high-speed camera to detect whether there are defects on the surface of the tablet body, so that the entire conveying line can also detect the surface defects of the tablet body during the conveying process of the tablet body.

[0023] An automatic conveying line for traditional Chinese medicine tablets provided by the present invention works under the alternating drive of the first and second half-tooth rings on the third rotating column through the air-blowing component, blowing air to flip the falling tablets, which can assist the high-speed camera to comprehensively detect the tablet body, improve the detection accuracy, and the air flow can buffer the tablets to prevent them from colliding and being damaged by the protective pad. When the first half-tooth ring meshes with the fourth helical gear, another air-blowing component works, and the cross pipe and the nozzle generate air flow to quickly blow the tablets at the bottom of the guiding frame onto the conveyor belt, avoiding the residue of the tablet body at the bottom of the guiding frame. At the same time, during this process, the semi-cylindrical block drives the connecting column and the fixed ball to rotate, squeezing the convex block to drive the connecting plate to drive the swinging pipe to swing reciprocally under the cooperation of the second spring, expanding the blowing area of the nozzle to prevent dead angles when blowing the tablets, ensuring the efficient and smooth entire conveying process of the tablet body.

[0038] A power assembly for driving the batching assembly to perform circular motion is arranged inside the box body 1;

[0039] Inside the box body 1, a vibration assembly 11 and a detection assembly are provided;

[0040] The batching assembly includes a circular frame 7 fixedly connected to the outer wall of the top of the box body 1. The circular frame 7 forms an angle of 15° with the horizontal direction. A feeding tray 8 is arranged inside the circular frame 7. Feeding holes 12 are formed in the top of the feeding tray 8. The specifications of the feeding holes 12 are adapted to the specifications of the tablet body 13. A blanking groove 45 is formed in the top of the box body 1. A baffle 9 is fixedly connected to the circumferential inner wall of the circular frame 7. By means of the batching assembly arranged on the top of the box body 1, with the circular frame 7 forming an angle of 15° with the horizontal direction, the tablet bodies 13 can be naturally stacked at the lower part of the circular frame 7. The feeding holes 12 on the feeding tray 8 are adapted to the specifications of the tablet bodies 13. During the rotation of the feeding tray 8, the tablet bodies 13 fall into the feeding holes 12 due to gravity, realizing automatic quantitative conveying. The baffle 9 in the circular frame 7 can scrape off the excess tablets on the top of the feeding tray 8, enabling them to participate in the quantitative conveying cycle again.

[0041] Preferably, the power assembly includes a motor 2 fixedly connected to the outer wall of one side of the box body 1. The output end of the motor 2 is fixedly connected to a second rotating column 33. A first bevel gear 37 is fixedly connected to the circumferential outer wall of the second rotating column 33. A second bevel gear 38 is meshed with the circumferential outer wall of the first bevel gear 37. A fixed seat 36 is fixedly connected to the inner wall of the bottom of the box body 1. The fixed seat 36 is rotationally connected to the second rotating column 33. A first rotating column 14 is fixedly connected to the circumferential inner wall of the second bevel gear 38. The first rotating column 14 is fixedly connected to the feeding tray 8. In the power assembly, the output end of the motor 2 is connected to the second rotating column 33. The second rotating column 33 drives the first bevel gear 37 to rotate. The first bevel gear 37 is meshed with the second bevel gear 38, thereby driving the first rotating column 14 to rotate, and then driving the feeding tray 8 to perform circular motion, providing power support for quantitative conveying.

[0042] Preferably, a semi-cylindrical block 15 is fixedly connected to the circumferential outer wall of the first rotating column 14. Two vibration assemblies 11 are arranged at both ends of the first rotating column 14. The vibration assembly 11 includes a fixed frame 1101. First springs 1102 are fixedly connected to both inner walls of the fixed frame 1101. One end of each first spring 1102 is fixedly connected to a rotating seat 1103. The rotating seat 1103 is rotatably connected to the first rotating column 14. Rectangular grooves 1104 are formed in both inner walls of the fixed frame 1101. A sliding column 1105 is fixedly connected to the circumferential outer wall of the rotating seat 1103. One end of the sliding column 1105 passes through the inside of the rectangular groove 1104. A limiting disc 1106 is fixedly connected to the circumferential outer wall of the sliding column 1105. A fixed frame 10 is fixedly connected to the top outer wall of the circular frame 7. The fixed frame 10 is fixedly connected to the fixed frame 1101. When the semi-cylindrical block 15 on the first rotating column 14 rotates, a centrifugal force is generated, which cooperates with the first spring 1102 in the vibration assembly 11. The fixed frame 1101 of the vibration assembly 11 is fixed to the top of the circular frame 7 through the fixed frame 10. Under the action of the first spring 1102, the rotating seat 1103 slides in the rectangular groove 1104 through the sliding column 1105, driving the feeding tray 8 to sway left and right, making it easier for the stacked tablet bodies 13 to be filled into the feeding holes 12, and improving the accuracy of quantitative conveying.

[0043] Preferably, a guiding frame 17 is fixedly connected to the inside of the box body 1. The guiding frame 17 is arranged directly below the material discharging groove 45. A protective pad 16 is adhesively connected to the inner wall of the guiding frame 17. An arc-shaped plate 25 is fixedly connected to one side of the protective pad 16. A material leakage groove is formed in the bottom inner wall of the guiding frame 17. The material leakage groove is located above the conveyor belt 6. Since the guiding frame 17 in the box body 1 is directly below the material discharging groove 45, the tablet bodies 13 falling from the feeding holes 12 enter the guiding frame 17 through the material discharging groove 45. At the same time, the protective pad 16 on the inner wall of the guiding frame 17 can protect the tablet bodies 13 from being damaged during the sliding process. The arc-shaped plate 25 helps to guide the sliding direction of the tablet bodies 13. The material leakage groove at the bottom of the guiding frame 17 enables the tablet bodies 13 to accurately fall onto the conveyor belt 6 for subsequent conveying.

[0044] Preferably, the detection assembly includes fixing plates 27 fixedly connected to both inner walls of the guiding frame 17. A high-speed camera 28 for detecting surface defects of the tablet bodies 13 is fixedly connected to the outer wall of one side of each fixing plate 27. The high-speed camera 28 in the detection assembly is fixed to the fixing plates 27 on both inner walls of the guiding frame 17. When the tablet bodies 13 fall from the material discharging groove 45 into the guiding frame 17, the high-speed camera 28 collects images of their surfaces, and can detect whether there are defects on the surfaces of the tablet bodies 13, realizing the quality detection function during the conveying process.

[0045] Preferably, one end of the second rotating column 33 is fixedly connected to a third rotating column 34. The circumferential outer wall of the third rotating column 34 is fixedly connected with a first half tooth ring 39 and a second half tooth ring 40 respectively. The first half tooth ring 39 and the second half tooth ring 40 are respectively engaged with a fourth helical gear 44 and a third helical gear 43. Blowing components 32 are arranged on the tops of the third helical gear 43 and the fourth helical gear 44. During the rotation of the third rotating column 34, the first half tooth ring 39 and the second half tooth ring 40 are alternately engaged with the fourth helical gear 44 and the third helical gear 43, thereby driving the blowing components 32 on the top to work and providing air flow power for auxiliary detection and cleaning of the tablets.

[0046] Preferably, the blowing component 32 includes an air collecting hood 3201 fixedly connected inside the box body 1. The circumferential inner wall of the air collecting hood 3201 is fixedly connected with a cross plate 3204. A rotating shaft 3203 is rotatably connected inside the cross plate 3204. A transverse plate 41 is fixedly connected to one inner wall of the box body 1. The rotating shaft 3203 is rotatably connected with the transverse plate 41. One end of the rotating shaft 3203 is provided with a shaft sleeve. The circumferential outer wall of the shaft sleeve is fixedly connected with a fan blade 3202. An air inlet hole is formed in the bottom of the box body 1 below the fan blade 3202. The air inlet hole at the bottom of the box body 1 allows external air to enter. After being accelerated by the fan blade 3202, an air flow is formed to provide an air source for subsequent blowing operations.

[0047] Preferably, a bent pipe 35 is fixedly connected to the top outer wall of one air collecting hood 3201. The other end of the bent pipe 35 is fixedly connected to a circular shell 31. Through holes 30 are formed in the bottom of the material guiding frame 17 and the protective pad 16. The through holes 30 are communicated with the circular shell 31. When the blowing component 32 works, the air flow is discharged upward through the bent pipe 35, the circular shell 31 and the through holes 30, and impacts against the falling tablet body 13, causing the tablet body 13 to flip, facilitating comprehensive detection by the high-speed camera 28, and at the same time playing a buffering role to prevent the tablet body 13 from vertically falling and contacting the protective pad 16 and being damaged.

[0048] Preferably, a first air duct 22 is fixedly connected to the top outer wall of the other air collecting hood 3201. The other end of the first air duct 22 is fixedly connected to a hose 21. The end of the hose 21 far from the first air duct 22 is fixedly connected to a swing pipe 23. Circular grooves 24 are formed on one side of the material guiding frame 17 and the protective pad 16. One end of the swing pipe 23 passes through the inside of the circular groove 24. A transverse pipe 26 is inserted into one end of the swing pipe 23. Nozzles 29 are inserted on the circumferential outer wall of the transverse pipe 26 at equidistant intervals. Both ends of the transverse pipe 26 are rotatably connected to the material guiding frame 17. When the corresponding blowing component 32 works, the air flow enters the transverse pipe 26 through the first air duct 22, the hose 21 and the swing pipe 23 and is blown out from the nozzles 29, quickly blowing the tablet body 13 at the bottom of the material guiding frame 17 onto the conveyor belt 6 to prevent tablet residues.

[0049] Preferably, a connecting plate 42 is fixedly connected to the circumferential outer wall of the swing pipe 23. On one outer wall of the connecting plate 42, second springs 46 are fixedly connected at equal intervals. The other ends of the second springs 46 are fixedly connected to one outer wall of the material guiding frame 17. A convex block 18 is fixedly connected to one outer wall of the connecting plate 42. A connecting column 20 is fixedly connected to the circumferential outer wall of the semi-cylindrical block 15. One end of the connecting column 20 is fixedly connected to a fixed ball 19. When the first rotating column 14 rotates, the semi-cylindrical block 15 drives the connecting column 20 and the fixed ball 19 to rotate. The fixed ball 19 presses against the convex block 18, causing the connecting plate 42 to drive the swing pipe 23 to rotate. After the fixed ball 19 separates from the convex block 18, the second spring 46 causes the connecting plate 42 and the swing pipe 23 to reset, realizing the reciprocating swing of the swing pipe 23, expanding the blowing area of the nozzle 29, and avoiding dead angles when blowing off the tablet body 13.

[0050] In summary, by means of the above technical solutions of the present invention, when it is necessary to convey the tablet body 13, the tablet body 13 can be first poured into the circular frame 7. Since the included angle between the circular frame 7 and the horizontal direction is 15°, the tablet body 13 poured into the circular frame 7 can be concentrated and stacked below the inside of the circular frame 7. Subsequently, the operator starts the motor 2, and the motor 2 can drive the second rotating column 33 and the first bevel gear 37 to rotate together. Through the meshing between the first bevel gear 37 and the second bevel gear 38, the first rotating column 14 can be driven to rotate together. And the feeding tray 8 located in the circular frame 7 is fixedly connected to the first rotating column 14. When the first rotating column 14 rotates, the feeding tray 8 can be driven to rotate together. At this time, when the feeding hole 12 opened on the feeding tray 8 rotates to the lower part of the stacked tablet body 13, the tablet body 13 will fall into the inside of the feeding hole 12 due to gravity, thus realizing the automatic quantitative conveying of the tablet body 13, meeting the use of people. And during the rotation of the feeding tray 8, a little of the tablet body 13 staying on the top of the feeding tray 8 can be scraped off by the baffle 9. After being scraped off, the tablet body 13 falls back to the stacking place again by gravity to carry out the quantitative conveying work of the next cycle;

[0051] And while the first rotating column 14 rotates, a certain centrifugal force will be generated by the semi-cylindrical block 15 provided on its outer wall. Through this centrifugal force and the combined action of the first spring 1102 in the vibration assembly 11, the feeding tray 8 can be shaken left and right while doing circular motion, so that the stacked tablet body 13 can be more easily filled into the feeding hole 12, avoiding the situation of missing filling, and ensuring the accuracy of the whole quantitative conveying process;

[0052] When the feeding hole 12 on the feeding tray 8 rotates to the blanking chute 45, the tablets in the feeding hole 12 will immediately fall into the guiding frame 17, and then fall into the conveyor belt 6 through the guiding frame 17 for subsequent conveying work. And during the process of the tablet body 13 falling from the blanking chute 45, the surface of the tablet body 13 can be imaged by the high-speed camera 28 to detect whether there are defects on the surface of the tablet body 13, so that the entire conveying line can also detect the surface defects of the tablet body 13 during the conveying process of the tablet body 13. At the same time, during the rotation of the second rotating column 33, the third rotating column 34 can be driven to rotate together, and the outer walls of the third rotating column 34 are respectively fixedly connected with a first half-tooth ring 39 and a second half-tooth ring 40. When the second half-tooth ring 40 meshes with the third helical gear 43, the first half-tooth ring 39 is separated from the fourth helical gear 44 at this time. The entire air-blowing assembly 32 is driven to work through the third helical gear 43, so that air can be blown into the circular shell 31 through the elbow pipe 35. The blown air is discharged upward through the through hole 30. The upward discharged air flow will counteract the falling tablet body 13, so that the tablet body 13 can be flipped during the falling process, enabling the high-speed camera 28 to detect each area of the tablet body 13, improving the detection accuracy of the tablet body 13. And the rising air flow can also play a good auxiliary buffering role, avoiding the situation that the tablet body 13 falls vertically and contacts the protective pad 16 and is damaged. As the third rotating column 34 continues to rotate, when the first half-tooth ring 39 meshes with the fourth helical gear 44, the second half-tooth ring 40 is separated from the third helical gear 43 at this time. At this time, the tablet body 13 falls to the bottom of the guiding frame 17 and gradually rolls onto the conveyor belt 6. At the same time, the rotation of the fourth helical gear 44 can drive another air-blowing assembly 32 to work, so that air flows can be generated in the cross pipe 26 and the nozzle 29. The air flow generated by the nozzle 29 can quickly blow the tablet body 13 falling on the bottom of the guiding frame onto the conveyor belt 6, avoiding the residue of the tablet body 13 on the guiding frame;

[0053] While the nozzle 29 generates an air flow to blow the tablet body 13, the semi-cylindrical block 15 can drive the connecting column 20 and the fixed ball 19 to rotate together. The convex block 18 can be squeezed through the fixed ball 19, so that the connecting plate 42 can drive the swing pipe 23 to rotate. When the fixed ball 19 is separated from the convex block 18, the connecting plate 42 and the swing pipe 23 can be reset through the second spring 46, so that the swing pipe 23 reciprocally swings while the nozzle 29 generates an air flow to blow the tablet body 13, effectively expanding the blowing area of the nozzle 29 and avoiding dead angles during the process of blowing the tablet body 13.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
