Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical dispensing equipment, and in particular to a counting plate vibration device. Background Technology

[0002] When bottling some pills or granules, counting plates are often used for counting and dispensing. In existing technology, multiple spaced-apart counting plates are used to convey and dispense the pills. Specifically, a dispensing device drops pills onto multiple counting plates, filling the pill holes. As the filled counting plates are conveyed, the pills are transported to the dispensing area. The dispensing area has separate collection bins for collecting the pills. After being conveyed to the dispensing area, the pills on the counting plates fall into the corresponding collection bins for collection, and then the filling is completed. The number of pills falling into the collection bins within a unit time interval remains relatively consistent, thus achieving the purpose of counting and dispensing pills per bottle.

[0003] However, during the process of the pills being transported from the counting plate to the dispensing area, due to the viscosity of the outer surface of the pills or the holes in the counting plate, or due to electrostatic adsorption of the pills, the pills cannot fall from the holes in the counting plate into the collection bin immediately after being transported to the dispensing area, resulting in inaccurate numbers of pills dispensed in each bottle. Utility Model Content

[0004] In view of the above problems, this utility model is proposed to provide a counting plate vibration device that overcomes or at least partially solves the above problems, and can solve the problem that pills cannot all fall into the collection chamber on the counting plate due to viscosity or static electricity.

[0005] Specifically, this utility model provides a vibrating device for counting plates, including a frame, on which two sprocket groups are arranged symmetrically from left to right.

[0007] Optionally, each link of the chain is provided with a connecting plate on its outer side, and the connecting plate has a threaded hole inside; Each of the counting plates has through holes at both ends. The two through holes are respectively aligned with the threaded holes at the same horizontal position of the chains on both sides.

[0008] Optionally, the outer edge of the outer ring of each bearing assembly is configured as a continuous, undulating wave shape, wherein the vertical distance between the crests and troughs of the wave shape is less than the height of the teeth in the third sprocket.

[0009] Optionally, it also includes a transmission mechanism and multiple bearing vibration drive mechanisms; each bearing vibration drive mechanism is mounted on the frame and connected to one of the bearing assemblies; The bearing vibration drive mechanism includes: a connecting frame, a translation rod, a cam, and an elastic element; The connecting frame is mounted on the frame; The translation rod passes through the connecting frame and slides longitudinally with the connecting frame. The front end of the translation rod extends out of the front side of the connecting frame and is connected to the bearing assembly at the end. The cam's shaft extends laterally and is rotatably connected to the connecting frame; the outer edge of the cam contacts the rear end of the translation rod. The elastic element extends longitudinally and is sleeved on the translation rod. One end is connected to the connecting frame and the other end is connected to the translation rod. It is configured to apply to the translation rod and move it backward, so that the rear end of the translation rod always abuts against the outer edge of the cam. The transmission mechanism is disposed between the two second sprockets and configured to transmit power from the two second sprockets to each of the cams.

[0010] Optionally, the connecting frame has a first rod and two second rods, the two second rods are arranged in parallel longitudinal direction, and the first rod is connected to the two ends on the same side of the two second rods; The first rod slides through the translation rod, and the translation rod extends to one end between the two second rods, where a rectangular plate is installed. One end of the elastic element is connected to the rectangular plate, and the other end is connected to the rear end of the first rod. The cam is rotatably connected to the rear ends of the two second rods. The width of the rectangular plate is equal to the distance between the two second rods.

[0011] Optionally, a limiting plate is installed between the two second rods, the translation rod passes longitudinally through the limiting plate, and the limiting plate is located behind the rectangular plate.

[0012] Optionally, the straight-line distance between the base circle radius and the maximum instantaneous radius of the cam is less than the height of the teeth in the third sprocket.

[0013] Optionally, the transmission mechanism includes a drive shaft and multiple belt drive components; The drive shaft extends laterally and is coaxially mounted between the two second sprockets; each of the belt drive components is connected between the drive shaft and each cam.

[0015] In the vibrating counting plate device of this utility model, multiple bearing assemblies abutting the rear end of the counting plate generate abutting pressure on the counting plate. The outer ring of the bearing assembly momentarily jams the counting plate at the third sprocket and the counting plate at the detachment from the third sprocket, causing the pills adhering to the medicine hole or attracted to the medicine hole by electrostatics to be driven out of the medicine hole, thereby completing the reliable detachment of the pills and ensuring the accurate quantity of medicine entering each bottle, achieving the purpose of accurate filling.

[0016] Furthermore, in the counting plate vibration device of this utility model, by tightening the positions of the two fastening nuts on the same threaded rod, the distance between the mounting rod and the lower frame of the mounting bracket is adjusted, thereby adjusting the position of the two bearing assemblies on the mounting rod. This changes the contact position between the two bearing assemblies and the rear end face of the counting plate, altering the contact pressure and thus changing the magnitude of the instantaneous stopping force. Users can flexibly adjust the instantaneous stopping force of the counting plate at the third sprocket according to actual needs, resulting in a high degree of adaptability.

[0017] Furthermore, in the counting plate vibration device of this utility model, when the two second sprockets rotate, they drive multiple cams to rotate synchronously through a power transmission mechanism. The rotation of the cams pushes the translation rod in the direction of rotation, compressing the elastic element. As the cams rotate, the elastic element applies a backward force to the translation rod, causing the translation plate to reciprocate along the longitudinal direction. This causes the bearing assembly at the end to continuously strike the rear end face of the counting plate, generating a continuous striking force that reliably dislodges the pill from the pill hole in the counting plate. In this embodiment, the synchronous rotation of the cams, in conjunction with the elastic element, applies a reciprocating force to the translation plate, thereby continuously striking the rear end face of the counting plate. This facilitates the reliable dislodgement of the pill from the pill hole in the counting plate. The rotation frequency of the cams is synchronized with the rotation frequency of the counting plate, ensuring that the striking frequency is synchronized with the rotation frequency of the counting plate. During rapid operation, a high-efficiency striking frequency is maintained, ensuring efficient dislodgement.

[0024] Figure 1 This is a three-dimensional schematic structural diagram according to an embodiment of the present utility model, such as... Figure 1 As shown, and refer to Figures 2 to 7 This utility model embodiment provides a vibrating device for a counting plate 7, including a frame 1. Two sprocket sets 2 are symmetrically arranged on the frame 1. The shafts of the sprockets in each sprocket set 2 extend laterally and are rotatably mounted on the frame 1. Specifically, the symmetrical structure of the sprocket sets 2 facilitates the transmission of the counting plate 7. Each sprocket set 2 includes multiple sprockets, each sprocket at a different position serving to plan the transmission path of the counting plate 7, thereby completing the process of loading and dispensing the medicine.

[0025] Each sprocket assembly 2 includes a first sprocket 3, a second sprocket 4, and a third sprocket 5. The first sprocket 3 is located at the rear of the frame 1, the second sprocket 4 is located on the upper side of the frame 1, and the third sprocket 5 is located at the front of the frame 1. Specifically, the three sprockets are arranged in a triangle. The travel area between the first sprocket 3 and the second sprocket 4 is the loading area, the travel area between the second sprocket 4 and the third sprocket 5 is the conveying area, the position of the third sprocket 5 is the drop position in the main dispensing area, and the travel area between the third sprocket 5 and the first sprocket 3 is the return area. The pills are loaded in the loading area, conveyed to the dispensing area, and then dropped and dispensed at the drop position. The counting plate 7 after dropping then returns through the return area.

[0026] Each sprocket assembly 2 is surrounded by a chain 6. Multiple counting plates 7 are installed between two chains 6, each extending laterally and spaced apart along the length of the chain 6. Specifically, the two chains 6 serve as transmission components, and the counting plates 7 are installed laterally between them, ensuring reliable sprocket-chain transmission. Furthermore, when a counting plate 7 rotates to the sprocket position, its upper and lower ends can be raised without affecting its transmission. The counting plates 7 in the return and loading zones are not shown in the attached diagram.

[0027] Multiple bearing assemblies 8 are arranged laterally on the frame 1, each positioned between two third sprockets 5. The inner ring of each bearing assembly 8 extends laterally and is mounted on the frame 1. The outer ring of each bearing assembly 8 abuts against the rear end face of the counting plate 7, generating abutment pressure on the counting plate 7. Specifically, each bearing assembly 8 has an inner ring, an outer ring, and internal balls, thus forming a bearing component. The bearing assemblies 8 are located in the area between the two third sprockets 5. While the outer ring of the bearing assembly 8 abuts against the rear end face of the counting plate 7, it can rotate with the counting plate 7. However, due to the abutment action of the bearing assembly 8 at the rear end of the counting plate 7, when the counting plate 7 rotates to the position of the third sprocket 5, the rear end of the counting plate 7 contacts the outer ring of the bearing component, causing a jam and generating a certain forward abutment force during the movement of the counting plate 7. Specifically, this abutment pressure does not cause the chain links at both ends of the counting plate 7 to disengage from the third sprockets 5. At this time, the back of the counting plate 7 is in line contact with the outer ring of the bearing assembly 8. After the contact is completed and the contact force is lost, the jamming occurs again. At the position of the third sprocket 5, most of the pills will fall off due to their own weight. For the pills that are stuck in the pill hole or attracted by static electricity, the jamming of the bearing assembly 8 will drive them out of the pill hole by the instantaneous jamming force, thus completing the reliable release of the pills.

[0028] When the counting plate 7 vibration device of this utility model is in use, the synchronous rotation of the first sprocket 3, the second sprocket 4 and the third sprocket 5 drives the two sets of chains 6 to move synchronously. During the movement, when it moves to the travel area between the first sprocket 3 and the second sprocket 4, the loading device on it fills the loading hole on the counting plate 7 in this area with pills. As it moves, it enters the travel area between the second sprocket 4 and the third sprocket 5. When the counting plate 7 moves to the third sprocket 5, the rear end of the counting plate 7 contacts the outer ring of the bearing and causes a momentary jam, generating a certain forward resisting force on the counting plate 7 during its movement. At this point, the back of the counting plate 7 is in line contact with the outer ring of the bearing assembly 8. After the contact is completed and the contact force disappears, a momentary jamming occurs again. At the position of the third sprocket 5, most of the pills will fall off due to their own weight. For pills that are stuck in the pill holes or attracted by static electricity, the momentary jamming of the bearing assembly 8 drives them out of the pill holes, thus completing the reliable detachment of the pills. The detached pills enter the corresponding collection chamber 30 for counting and collection, thus completing the subsequent single-bottle filling. The detached counting plate 7 moves into the travel area between the third sprocket 5 and the first sprocket 3 to form a cycle.

[0029] In this embodiment of the invention, multiple bearing assemblies 8 abutting the rear end of the counting plate 7 generate abutting pressure on the counting plate 7. The outer ring of the bearing assembly 8 momentarily jams the counting plate 7 at the third sprocket 5 and the counting plate 7 disengaging from the third sprocket 5, causing the pills adhering to or attracted to the medicine hole due to electrostatic attraction to be driven out of the medicine hole, thereby completing the reliable disengagement of the pills and ensuring the accurate quantity of medicine entering each bottle, achieving the purpose of precise filling.

[0030] In some embodiments of this utility model, such as Figure 2 As shown, it also includes multiple mounting racks 9. Each mounting rack 9 is arranged at a horizontal interval and is installed at an angle on the frame 1. Each mounting rack 9 is a rectangular frame structure. Specifically, the number of each mounting rack 9 matches the number of collection bins 30.

[0031] Two bearing assemblies 8 are disposed on the underside of the mounting bracket 9 and are installed via connecting assembly 10. That is, two bearing assemblies 8 are installed on the underside of each mounting bracket 9 to ensure that the force on the number plate 7 at the same location is uniform.

[0032] The connecting assembly 10 includes a mounting rod 11, two threaded rods 12, and four sets of fastening nuts 13. One threaded rod 12 engages with both fastening nuts 13. The mounting rod 11 extends laterally and is positioned on the lower side of the mounting bracket 9. The two threaded rods 12 are arranged parallel and spaced apart, with their lower ends connected to the upper side of the mounting rod 11, and their upper ends extending upwards and passing through the lower frame of the mounting bracket 9. Specifically, the mounting rod 11 and the two threaded rods 12 form a U-shaped structure, with the two threaded rods inserted into the lower frame of the mounting bracket 9 along its inclined direction.

[0033] Each threaded rod 12 has an external thread 14 at the portion passing through the lower frame of the mounting bracket 9. Two fastening nuts 13 are threaded into the external thread 14 and are respectively placed on the upper and lower sides of the lower frame of the mounting bracket 9. Specifically, the distance between the mounting rod 11 and the lower frame of the mounting bracket 9 can be adjusted by tightening the fastening nuts 13 on the upper and lower sides, thereby achieving the purpose of adjusting the height. Bearing assemblies 8 are installed at both ends of the mounting rod 11.

[0034] In this embodiment of the invention, by tightening the positions of the two fastening nuts 13 on the same threaded rod 12, the distance between the mounting rod 11 and the lower frame of the mounting bracket 9 is adjusted, thereby adjusting the positions of the two bearing assemblies 8 on the mounting rod 11. This changes the contact position between the two bearing assemblies 8 and the rear end face of the counting plate 7, altering the contact pressure and thus changing the magnitude of the instantaneous locking force. Users can flexibly adjust the instantaneous locking force of the counting plate 7 at the third sprocket 5 according to actual needs, resulting in a high degree of adaptability.

[0035] In some embodiments of this utility model, such as Figure 2 As shown, each link of the chain 6 is provided with a connecting plate 15 on its outer side, and the connecting plate 15 has a threaded hole. Specifically, the threaded hole corresponds to the space area in the middle of the connection.

[0036] Each counting plate 7 has through holes at both ends, which are aligned with threaded holes at the same horizontal position on both sides of the chain 6. Fastening bolts 16 are threaded into these through holes. Specifically, the counting plates 7 are installed on the links of the two chains 6 in the same horizontal direction using the fastening bolts 16. This allows the counting plates 7 to have a small degree of freedom when passing each sprocket, enabling them to momentarily stop. The length of a single chain link can be equal to or unequal to the width of the counting plate 7; the counting plate 7 simply needs to be installed on a single chain link during installation.

[0037] In an embodiment of the utility model, the counting plate 7 is installed on the links of two chains 6 in the same horizontal direction by fastening bolts 16, so that the counting plate 7 can have a small degree of freedom when passing each sprocket, so as to make a momentary stop.

[0038] In some embodiments of this invention, the outer edge of the outer ring of each bearing assembly 8 is configured as a continuous, undulating wave shape, with the vertical distance between the crests and troughs of the wave shape being less than the height of the teeth in the third sprocket 5. In this embodiment, the wave shape allows the outer ring to move with the counting plate 7 during contact with its rear end face, and also applies intermittent locking forces to the counting plate 7 during rotation, ensuring that the pills on the counting plate 7 can completely detach from the medicine hole. The fact that the vertical distance between the crests and troughs of the wave shape is less than the height of the teeth in the third sprocket 5 ensures that the chain links at both ends of the counting plate 7 will not detach from the third sprocket 5 during the locking process caused by the outer ring, ensuring safety and reliability.

[0039] In some embodiments of this utility model, such as Figure 6 As shown, the vibration device of the counting plate 7 also includes a transmission mechanism 18 and multiple bearing vibration drive mechanisms 17. Each bearing vibration drive mechanism 17 is mounted on the frame 1 and connected to one of the bearing assemblies 8. That is, power is transmitted to the bearing vibration drive mechanism 17 through the transmission mechanism 18, and thus transmitted to the bearing assembly 8.

[0040] The bearing vibration drive mechanism 17 includes: a connecting frame 19, a translation rod 20, a cam 21, and an elastic element 22.

[0041] The connecting frame 19 is mounted on the frame 1. A translation rod 20 passes through the connecting frame 19 and slides longitudinally with it. The front end of the translation rod 20 extends beyond the front side of the connecting frame 19 and connects to the bearing assembly 8 at its end. Specifically, the longitudinal sliding engagement between the translation rod 20 and the connecting rod involves a rectangular hole in the connecting frame 19, within which the translation rod 20 slides, allowing it to move only longitudinally along the connecting frame 19.

[0042] The cam 21 has a lateral axis and is rotatably connected to the connecting bracket 19. The outer edge of the cam 21 contacts the rear end of the translation rod 20.

[0043] The elastic element 22 extends longitudinally and is sleeved on the translation rod 20. One end is connected to the connecting frame 19, and the other end is connected to the translation rod 20. It is configured to apply force to the translation rod 20 and move it backward, causing the rear end of the translation rod 20 to always abut against the outer edge of the cam 21. That is, the cam 21 pushes the translation rod 20 towards the rear, compressing the elastic element 22. As the cam 21 rotates, the elastic element 22 applies a rearward force to the translation rod 20, causing the translation plate to reciprocate along the longitudinal direction, thereby causing the bearing assembly 8 at the end to continuously strike the rear end face of the counting plate 7. This generates a continuous striking force, reliably dislodging the pill from the medicine hole in the counting plate 7.

[0044] The transmission mechanism 18 is positioned between the two second sprockets 4 and configured to transmit the power from the two second sprockets 4 to each cam 21. In other words, the power mechanism transmits the synchronized rotational power of the two sprockets to each cam 21. If the counting plate 7 has a high conveying speed, the cam 21 rotates quickly, resulting in a high frequency of continuous striking. Conversely, the striking frequency is slow. The striking frequency is synchronized with the conveying speed of the counting plate 7.

[0045] In use, the vibration device of the counting plate 7 of this utility model, when the two second sprockets 4 rotate, drive multiple cams 21 to rotate synchronously through the power transmission mechanism 18. The rotation of the cams 21 pushes the translation rod 20 in the direction of rotation, compressing the elastic element 22. As the cams 21 rotate, the elastic element 22 applies a backward force to the translation rod 20, causing the translation plate to reciprocate along the longitudinal direction, thereby causing the bearing assembly 8 at the end to continuously strike the rear end face of the counting plate 7. This generates a continuous striking force, reliably detaching the pill from the pill hole in the counting plate 7. In this embodiment, the synchronous rotation of the cams 21, in conjunction with the elastic element 22, applies a reciprocating force to the translation plate, thereby continuously striking the rear end face of the counting plate, which is beneficial for the reliable detachment of the pill from the pill hole in the counting plate. The rotation frequency of the cams 21 is kept synchronous with the rotation of the counting plate, so that the striking frequency is also synchronous with the rotation of the counting plate. During rapid operation, a high-efficiency striking frequency is maintained, ensuring detachment efficiency.

[0046] In some embodiments of this utility model, such as Figure 7 As shown, the connecting frame 19 has a first rod 23 and two second rods 24, which are arranged parallel longitudinally. The first rod 23 is connected to the two ends of the two second rods 24 on the same side. That is, a U-shaped structure is formed between the two second rods 24 and the first rod 23. A translation rod 20 slides through the first rod 23. A rectangular plate 25 is installed at one end of the translation rod 20 between the two second rods 24. One end of the elastic element 22 is connected to the rectangular plate 25, and the other end is connected to the rear end of the first rod 23. A cam 21 is rotatably connected to the rear end of the two second rods 24. The width of the rectangular plate 25 is equal to the distance between the two second rods 24.

[0047] In this embodiment, the rectangular plate 25 allows the translation plate to reliably move between the two second rods 24 without rotation or displacement in other directions, thus ensuring the reliability of the movement.

[0048] In some embodiments of this utility model, such as Figure 7 As shown, a limiting plate 26 is installed between the two second rods 24, and the translation rod 20 passes longitudinally through the limiting plate 26. The limiting plate 26 is located behind the rectangular plate 25. The limiting plate 26 is used to limit the extreme position of the translation rod 20's rearward movement. By setting the limiting plate 26, the position of the translation plate's rearward movement can be limited, thus eliminating the need to strictly pursue the design of the cam 21's major and minor diameters.

[0049] In some embodiments of this invention, the linear distance between the base circle radius and the maximum instantaneous radius of the cam 21 is less than the height of the teeth in the third sprocket 5. This ensures that the chain links at both ends of the counting plate 7 will not detach from the third sprocket 5 during the impact of the outer ring, thus ensuring safety and reliability.

[0050] In some embodiments of this utility model, such as Figure 6 As shown, the transmission mechanism 18 includes a drive shaft 27 and multiple belt drive components. The drive shaft 27 extends laterally and is coaxially mounted between two second sprockets 4. Each belt drive component connects the drive shaft 27 to each cam 21. Each belt drive component includes two drive pulleys 28 and a drive belt 29, with the drive belt 29 sleeved between the two drive pulleys 28. One drive pulley 28 is fixed to the drive shaft 27, and the other drive pulley 28 is fixed to the cam 21. In this embodiment, the belt drive ensures reliable power transmission.

[0051] In some embodiments of this utility model, such as Figure 1As shown, it also includes multiple collection chambers 30. The number of collection chambers 30 is consistent with the number of bearing vibration drive mechanisms 17. The multiple collection chambers 30 are arranged laterally at intervals and installed at the front end of the frame 1. The multiple collection chambers 30 are located on the front side of multiple counting plates 7 and laterally separate the multiple counting plates 7. In this embodiment, by using the collection chambers 30 set at the second sprocket 4, the pills on the counting plates 7 within a unit interval can be collected. For example, each interval of collection chamber 30 corresponds to three sets of pill holes on the counting plate 7, and the three sets of counting plates 7 hold six pills. As the counting plates 7 rotate, after rotating through ten sets of counting plates 7, the number of pills falling into the collection chamber 30 is sixty. This achieves the purpose of accurate counting.

[0052] In some embodiments of this utility model, such as Figure 3 As shown, the angle of inclination of the line connecting the center points of the first sprocket 3 and the second sprocket 4 is generally between 25 and 35 degrees with the horizontal direction, ensuring that pills falling onto them can reliably roll into the pill holes on the counting plate 7. The angle of inclination of the line connecting the center points of the first sprocket 3 and the second sprocket 4 is generally between 45 and 55 degrees with the horizontal direction. The angle of inclination of the line connecting the center points of the first sprocket 3 and the second sprocket 4 is generally between 5 and 15 degrees with the horizontal direction.

[0053] In some embodiments of this utility model, such as Figure 1 As shown, the two first sprockets 3 serve as the power input components of the chain 6. Pulleys are installed coaxially on the shafts of the two first sprockets 3, and power input is achieved by setting a belt drive between the output shaft of the drive motor and the shaft.

[0054] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
