Description
Technical Field
[0001] This utility model relates to a tablet testing instrument in the pharmaceutical and health product fields, and in particular a multifunctional tablet testing instrument. Background Technology
[0002] Many pharmaceutical and health product manufacturing standards stipulate that tablet production must be carried out on-site for sampling and testing of indicators such as tablet hardness, weight, and thickness. Currently, while there are many automated tablet weight testing devices, hardness testing mostly involves manual feeding, squeezing the tablets using a simple press, and then manually removing any fragments. Thickness testing is mostly done manually with calipers. These processes are labor-intensive and the quality of testing is uncontrollable. Existing technologies rarely offer fully automated equipment that can comprehensively test weight, hardness, and thickness; most are complex in structure and cumbersome in operation. For example, during feeding, it is difficult to separate adjacent tablets, resulting in uncontrollable and slow separation, and uncontrollable tablet posture; the feeding mechanism cannot serve as a testing platform, and the material transfer structure is complex; the fragment removal mechanism after tablet crushing is complex; and the single-layer material transfer mechanism leads to low efficiency for each functional testing platform. Utility Model Content
[0003] This invention addresses the shortcomings of existing technologies by proposing a tablet detector.
[0004] The technical measures adopted in this utility model are as follows: a tablet detector, comprising a control cabinet, a base, and a feeding device, a transferring device, and a squeezing device mounted on the base. The squeezing device includes a linear drive device and its driven pressure head, a pressure seat connected to a force sensor, and a squeezing platform located in front of and below the pressure seat. The force sensor is connected to the base. A separation trough exists between the transferring device and the feeding device. The feeding device connects to the separation trough, which is connected to a third linear vibrator. At the material outlet, the separation trough gradually transforms into a preparation platform. Both the preparation platform and the squeezing platform are horizontally arranged. The independently vibrating preparation platform makes it easier to separate adjacent tablets from the feeding device, resulting in controllable and faster separation. Compared to the drop-feed method, the tablet posture of the vibrating and translating feeding is more controllable. The squeezing platform is not higher than the preparation platform. The transferring device consists of a linear drive device and its driven displacement rod, with the displacement rod aligned with the line connecting the squeezing platform and the preparation platform. When the preparation platform stops vibrating, various functional tests can be performed directly on the tablets, resulting in higher structural utilization.
[0005] Another specific feature of this solution is that the extrusion platform is connected to the fourth linear vibrator, and the extruded fragments can be automatically vibrated and conveyed out of the extrusion platform.
[0006] The machine base also has a linear thickness gauge fixed to the base. Its test head is a linearly moving thickness gauge push rod. The thickness gauge is placed below the side of the material preparation platform. One end of the thickness gauge push rod is fixed to the thickness plate by a cantilever. The other end of the thickness gauge push rod is supported in a non-fixed manner by a vertically movable device. The thickness plate faces the material preparation platform. The moving direction of the thickness gauge push rod is perpendicular to the material preparation platform. The plane of the thickness plate is perpendicular to the thickness gauge push rod. Before testing the tablet thickness, the vertically movable device is first lowered to touch the material preparation platform to find the zero point. Then, the tablet enters the material preparation platform, and the vertically movable device is lowered again to touch the tablet. The difference between the two readings of the thickness gauge is the tablet thickness.
[0007] The feeding device includes a feeding trough and a queuing trough connected to it. The feeding trough is connected to a first linear vibrator, the queuing trough is connected to a second linear vibrator, and the queuing trough is connected to a separation trough.
[0008] The linear drive mechanism of the shifting device includes a shifting motor, a shifting guide rail, a shifting slider, and a shifting light-blocking plate connected to the shifting slider. It also includes a third photoelectric sensor and a fourth photoelectric sensor fixed to the base. A shifting rod is connected to the shifting slider. For easy disassembly and cleaning, a shifting head is connected to the end of the shifting rod. The end of the shifting head that contacts the tablet is shaped like a knife handle, which can intercept tablets vibrating from the preparation platform, achieving rapid feeding without allowing tablets to escape from the platform. It also prevents the knife handle from contacting the tablet when the shifting head retracts. The shifting slider is connected to the shifting light-blocking plate. The light-blocking signal when the shifting light-blocking plate passes through the third and fourth photoelectric sensors can be used to determine the position of the shifting head, thereby determining the position of the tablet being detected.
[0009] The linear drive unit of the extrusion device includes an extrusion guide rail rigidly connected to the machine base, an extrusion slide block driven by a screw that slides on the extrusion guide rail, and an extension block connected to the extrusion slide block. The press head is installed at the end of the extension block, which can be easily disassembled and cleaned. The screw is connected to the drive motor through a coupling or gear belt.
[0010] The extrusion platform is connected to the fourth linear vibrator via the fourth vibrator connector. The pressure seat is connected to the force sensor via the extrusion connector, and the force sensor is connected to the machine base via the extrusion connector. The pressure seat, extrusion connector, and force sensor are connected together in a cantilevered manner, facing the pressure head.
[0011] The upper surface of the extrusion platform also has grooves parallel to the running direction of the press head. The cross-sectional shape of the press head is also adapted to the cross-sectional shape of the extrusion platform so that the two surfaces can move relative to each other in close contact. When encountering long strip tablets, the transfer head moves the long strip tablets to the groove. The fourth linear vibrator vibrates to make the long strip tablets lie parallel in the groove along the length direction. Finally, the press head extrudes the tablets along the length direction of the tablets.
[0012] If no fragmentation agent is needed, the shifting head continues to eject the tablet until it is pushed into the complete hopper.
[0013] The tablets stored in the feeding trough are slowly output to the queuing trough, which lines the tablets into a queue and outputs them one by one. After a tablet is detected by a photoelectric sensor and output to the separation trough, the feeding trough and the queuing trough stop vibrating. This tablet is separated from the subsequent tablets. The third linear vibrator continues to move the tablet until it is moved to the preparation platform. At this time, there is only one tablet on the preparation platform. Then, the shifting head moves this tablet to various test positions.
[0014] When the tablets reach the extrusion platform, the control cabinet controls the pressure head to move linearly and extend, extruding the tablets directly in front of the pressure seat. After the tablets are broken, the pressure head retracts. At the same time, the fourth linear vibrator drives the extrusion platform to vibrate, conveying the broken tablets in the direction of the retracted pressure head to the crushing bin located at the lower end of the extrusion platform.
[0015] There is at least one test platform between the material preparation platform and the extrusion platform, and the stroke of the shift rod spans across the material preparation platform, the test platform, and the extrusion platform.
[0016] One of the testing platforms is the second testing platform. The second testing platform does not contact the other platforms. It is connected to the load-bearing end of the weighing sensor fixed on the base through a weighing transition block. The weighing sensor is connected to the control cabinet to realize the test of tablet weight.
[0017] The thickness gauge can be placed directly above the material preparation platform. The lower end of the thickness gauge's top rod is fixed to the thickness measuring plate, while the upper end of the thickness gauge's top rod is supported in a non-fixed manner by a vertically movable device. The thickness gauge's top rod moves downward to test the position of the material preparation platform and the tablets respectively, thereby obtaining the tablet thickness.
[0018] A discharge bin is set below the material preparation platform along its vibrating conveying direction. When the number of tablets tested exceeds the number required to be tested, the tablets from the queuing trough can be directly conveyed to the discharge bin instead of being sent to each testing platform, so as to facilitate recycling and save costs.
[0019] The material transfer rod transforms into a double-layered fork-shaped fork plate seat, extending two parallel flat plates arranged vertically, serving as the upper and lower plates respectively. For easy disassembly and cleaning, the upper plate aligns with the upper transfer plate, and the lower plate aligns with the lower transfer plate. From top to bottom, the upper transfer plate, preparation platform, lower transfer plate, and weighing platform are arranged sequentially. The fork plate seat drives the upper and lower transfer plates to move horizontally in a straight line. The preparation platform is interspersed between the upper and lower transfer plates, and the lower transfer plate is interspersed between the weighing platform and the preparation platform. All plates and platforms do not interfere with each other. The upper transfer plate and preparation platform... The spacing between the forklift plates is less than the thickness of the tablets. The spacing between the preparation platform and the lower transfer plate is less than the thickness of the tablets. The spacing between the lower transfer plate and the weighing platform is less than the thickness of the tablets. The height of the weighing platform is not less than the height of the extrusion platform. At the maximum stroke of the forklift plate, the length of the lower transfer plate plus the length of the lower plate can reach the side of the extrusion platform closest to the complete hopper. At this time, the forklift plate does not interfere with the preparation platform. The total length of the lower transfer plate plus the lower plate is greater than the total length of the upper transfer plate plus the upper plate than the length of the preparation platform in the stroke direction of the forklift plate. When the forklift plate extends to transfer material, the upper transfer plate first moves the tablets off the preparation platform. The tablets fall onto the upper surface of the lower transfer plate. The forklift plate retracts, and the tablets are blocked by the preparation platform and fall onto the weighing platform. The next time the forklift extends to transfer material, the upper transfer plate first moves the tablets off the preparation platform, and the tablets fall onto the upper surface of the lower transfer plate. At the same time, the lower transfer plate moves the tablets that were originally on the weighing platform to the extrusion platform. The forklift retracts, and the tablets on the lower transfer plate are blocked by the preparation platform and fall onto the weighing platform.
[0020] In this way, tablets from two test platforms can be moved simultaneously to the next two test platforms each time. Compared to the single transfer head method, which can only move one tablet to the next test platform at a time while leaving the other test platforms idle, this method greatly improves efficiency.
[0021] First, a separation tank exists between the transfer device and the feeding device. This separation tank transforms into a platform at the material outlet, allowing tablets to be spaced apart for convenient testing. The feeding process is controllable; the feeding platform contains only one tablet, which can be directly used as a testing platform. The operation is simple and space-saving.
[0022] II. The material transfer device consists of a linear drive unit and its driven displacement rod. The displacement rod is directly opposite the line connecting the extrusion platform and the material preparation platform. The material transfer structure is simple and economical.
[0023] Third, the extrusion platform is connected to the fourth linear vibrator, making the removal of tablet fragments simpler and more automatic after hardness testing.
[0024] Fourth, the long-stroke shifting head and complete hopper can significantly reduce tablet costs, and tablets that do not need to be crushed to test hardness can be recycled.
[0025] 5. The material transfer head cutter handle design facilitates the consistency of all material movement trajectories, making testing more controllable.
[0026] VI. The groove design and vibration conditioning of the indenter enable the compression test of long strip tablets in the length direction.
[0027] 7. Using a linear thickness gauge, the tablet thickness is measured twice by lifting it with its top rod in a non-fixed manner. This method is simple and economical.
[0028] 8. The weighing platform is designed between the material preparation platform and the extrusion platform, allowing multiple platforms to work simultaneously for higher efficiency.
[0029] 9. A discharge hopper is set up in front of the material preparation platform to recycle excess test tablets and save costs.
[0030] 10. The double-layer transfer plate design of the fork seat plate allows one transfer mechanism to move materials on multiple workstations simultaneously, greatly improving inspection efficiency. Attached Figure Description

Detailed Implementation
[0040] Example 1: A tablet detector, see Figure 1-2 It includes a control cabinet, a base 29, and a feeding device, a transferring device, and an extrusion device mounted on the base 29. The feeding device includes a feeding trough 1 and a queuing trough 2. The feeding trough 1 is connected to a first linear vibrator 27, and the queuing trough 2 is connected to a second linear vibrator 26. The extrusion device includes a linear drive device and its driven pressure head 22, a pressure seat 32 connected to a force sensor 15, and an extrusion platform 20 located in front of and below the pressure seat 32. The force sensor 15 is connected to the base 29. There is also a separation trough 3 between the transferring device and the feeding device. The queuing trough 2 connects to the separation trough 3, and the separation trough 3 is connected to a third linear vibrator 24. The separation trough 3 gradually changes from a trough to a platform at the material outlet. This platform is called the material preparation platform 51. The material preparation platform 51 and the extrusion platform 20 are connected. All components are arranged horizontally, with the extrusion platform 20 not higher than the material preparation platform 51. The material transfer device consists of a linear drive device and its driven displacement rod 56. The displacement rod 56 is directly opposite the line connecting the extrusion platform 20 and the material preparation platform 51. The extrusion platform 20 is connected to the fourth linear vibrator.
[0041] The linear drive device of the extrusion unit includes an extrusion guide rail 23 rigidly connected to the base 29, an extrusion slider 25 driven by a screw and sliding on the extrusion guide rail 23, and an extension block 33 connected to the extrusion slider 25. The pressure head 22 is installed at the end of the extension block 33, which can be easily disassembled and cleaned. The screw is connected to the drive motor through a coupling 66 or a gear belt.
[0042] The extrusion platform 20 is connected to the fourth linear vibrator 16 via the fourth vibrator connector 41. The pressure seat 32 is connected to the force sensor 15 via the extrusion connector 31. The force sensor 15 is connected to the machine base 29 via the extrusion connector 40. The pressure seat 32, the extrusion connector 31, and the force sensor 15 are connected together in a cantilevered manner and face the pressure head 22.
[0043] The linear drive device of the shifting device includes a shifting motor 42, a shifting guide rail 73, a shifting slider 9, and a shifting light-blocking plate 35 connected to the shifting slider 9. It also includes a third photoelectric sensor 34 and a fourth photoelectric sensor 57 fixed to the base 29. A shifting rod 56 is connected to the shifting slider 9. For easy disassembly and cleaning, a shifting head 58 is connected to the end of the shifting rod 56. The end of the shifting head 58 that contacts the tablet is designed in a shape similar to a knife handle, which can intercept the tablets 12 vibrating from the preparation platform 51 and prevent the knife handle from contacting the tablets 12 when it retracts. The shifting slider 9 is connected to the shifting light-blocking plate 35. The light-blocking signal when the shifting light-blocking plate 35 passes through the third photoelectric sensor 34 and the fourth photoelectric sensor 57 can be used to determine the position of the shifting head 58, thereby determining the position of the tablet being detected.
[0044] See Figure 3-8 The tablets stored in the feeding trough 1 are slowly output to the queuing trough 2. The queuing trough 2 arranges the tablets in a queue and outputs them one by one. After the first photoelectric sensor 37, which shines on the outlet of the feeding trough 1, detects that a tablet has been output to the separation trough 3, the feeding trough 1 and the queuing trough 2 stop vibrating. This tablet 12 is separated from the subsequent tablets. The third linear vibrator 24 continues to move the tablet 12 until the tablet is moved to the preparation platform 51 and is detected by the second photoelectric sensor 21. At this time, there is only one tablet 12 on the preparation platform 51. Then, the shifting head 58 moves this tablet 12 to each test position.
[0045] See Figure 3-4 When the tablets reach the extrusion platform 20, the control cabinet controls the pressure head 22 to move linearly and extend, extruding the tablets directly in front of the pressure seat 32. After the tablets are broken, the pressure head 22 retracts. At the same time, the fourth linear vibrator 16 drives the extrusion platform 20 to vibrate, conveying the broken tablets in the direction of the retraction of the pressure head 22 to the crushing bin 19 located on the lower side of the end of the extrusion platform 20.
[0046] The upper surface of the extrusion platform 20 also has grooves parallel to the running direction of the extruder head 22. The cross-sectional shape of the extruder head 22 is also adapted to the cross-sectional shape of the extrusion platform 20 so that the surfaces of the two can move relative to each other in close contact. When encountering a long strip tablet, the transfer head 58 moves the long strip tablet to the groove. The fourth linear vibrator 16 vibrates to make the long strip tablet lie parallel to the length direction in the groove. The extruder head 22 finally extrudes the tablet along the length direction of the tablet. If the tablet is not required to crush the tablet, the transfer head 58 continues to push the tablet until it is pushed into the complete material hopper 17.
[0047] Example 2: A tablet detector, similar to Example 1, will not be repeated here. See [link to example]. Figure 3-8 The difference lies in that the base 29 also has a linear thickness gauge fixed to the base 29. Its test head is a linearly moving thickness gauge rod 7. One end of the thickness gauge rod 7 is fixed to the thickness plate 4 through the cantilever 6, and the other end of the thickness gauge rod 7 is supported in a non-fixed manner by a vertically movable device. The thickness plate 4 is directly facing the material preparation platform 51. The moving direction of the thickness gauge rod 7 is perpendicular to the material preparation platform 51. The thickness plate 4 is perpendicular to the thickness gauge rod. Before the tablet thickness test, the vertically movable device is first lowered to touch the material preparation platform 51 to find the zero point of the thickness test. Then, the tablet 12 enters the material preparation platform 51, and the vertically movable device is lowered to touch the tablet again. The difference between the two readings of the thickness gauge is the thickness of the tablet 12.
[0048] The thickness gauge can be placed directly above the material preparation platform 51. The lower end of the thickness gauge top rod 7 is fixed to the thickness measuring plate, and the upper end of the thickness gauge top rod 7 is supported in a non-fixed manner by a vertically movable device. The thickness gauge top rod 7 moves downward to test the position of the material preparation platform 51 and the tablet respectively, and the thickness of the tablet 12 is obtained.
[0049] Example 3: A tablet detector, similar to Example 1, will not be repeated here. See [link to example]. Figure 1-8 The difference is that there is at least one test platform 65 between the material preparation platform 51 and the extrusion platform 20, and the stroke of the shift rod 56 spans the material preparation platform 51, the test platform 65, and the extrusion platform 20.
[0050] Example 4: A tablet detector, similar to Example 3, will not be repeated here. See [link to example]. Figure 3-8 The difference is that one of the test platforms 65 is the second test platform 18. The second test platform 18 does not contact the other platforms. It is connected to the bearing end of the weighing sensor 30 fixed on the base 29 through the weighing transition block 28. The weighing sensor 30 is connected to the control cabinet to realize the weight test of the tablet 12.
[0051] See Figure 5-8The material preparation platform 51 is provided with a discharge bin 14 below its vibration conveying direction. When the number of tests exceeds the number of tests required, the tablets 12 from the queuing tank 2 can be directly conveyed to the discharge bin 14 instead of being sent to each test platform for recycling.
[0052] Example 5: A tablet detector, similar to Example 4, will not be repeated here. See [link to example]. Figure 3-8 The difference lies in that the material transfer rod 56 is replaced by a double-layer fork-shaped fork plate seat 5, which extends two parallel flat plates arranged vertically, namely the upper plate and the lower plate. The upper plate connects to the upper material transfer plate 10, and the lower plate connects to the lower material transfer plate 13. From top to bottom, the upper material transfer plate 10, the preparation platform 51, the lower material transfer plate 13, and the weighing platform 18 are arranged in sequence. The fork plate seat 5 drives the upper material transfer plate 10 and the lower material transfer plate 13 to move horizontally in a straight line. The preparation platform 51 is inserted between the upper material transfer plate 10 and the lower material transfer plate 13, and the lower material transfer plate 13 is inserted between the weighing platform 18 and the preparation platform 51. All the flat plates and platforms do not interfere with each other. The upper material transfer plate 10 and the preparation platform 51 are connected by a fork plate seat 51. The spacing between the two sides is less than the thickness of the tablet 12. The spacing between the preparation platform 51 and the lower transfer plate 13 is less than the thickness of the tablet 12. The spacing between the lower transfer plate 13 and the weighing platform 18 is less than the thickness of the tablet 12. The height of the weighing platform 18 is not less than the height of the extrusion platform 20. At the maximum stroke of the fork plate 5, the length of the lower transfer plate 13 plus the length of the lower plate can reach the side of the extrusion platform 20 close to the complete material bin 17. At this time, the fork plate 5 does not interfere with the preparation platform 51. The total length of the lower transfer plate 13 plus the lower plate is greater than the total length of the upper transfer plate 10 plus the upper plate than the length of the preparation platform 51 in the stroke direction of the fork plate 5. When the fork plate 5 extends to transfer material, the upper transfer plate 10 first moves the tablets on the preparation platform 51 out of the preparation platform 51. The tablet 12 falls onto the upper surface of the lower transfer plate 13. The fork plate 5 retracts, and the tablet 12 is blocked by the preparation platform 51 and falls onto the weighing platform 18. The next time the fork plate seat 5 extends to transfer material again, the upper transfer plate 10 first moves the tablets 12 off the preparation platform 51, and the tablets 12 fall onto the upper surface of the lower transfer plate 13. At the same time, the lower transfer plate 13 moves the tablets 12 that were originally on the weighing platform 18 to the extrusion platform 20. The fork plate seat 5 retracts, and the tablets 12 on the lower transfer plate 13 are blocked by the preparation platform 51 and fall onto the weighing platform 18.
[0053] In this way, tablets from two test platforms can be moved simultaneously to the next two test platforms each time. Compared to the single transfer head 58, which can only move one tablet to the next test platform at a time while leaving the other test platforms idle, this method greatly improves efficiency.
