[0002] In the pharmaceutical industry, a swinging tablet counter is usually used in the process of filling tablets and capsules into medicine bottles. The working principle of the swinging tablet counter is that there are several counting holes on the counting disc. When working, the counting holes will rotate around the axis of the counting disc. During this period, the drugs will be stuck in the counting holes and will be connected with the feeding hole at a certain moment, and finally the drugs will fall into the filling container. The swinging tablet counter is mainly used to ensure the balanced dosage of drugs in each bottle of medicine.

[0003] The traditional swing tablet counter can basically realize the one-to-one positioning of the tablet counting holes and the drugs by relying on the drug's own weight. However, when filling tablets, tablets may be stacked, resulting in multiple tablets being stuck in one tablet counting hole, which leads to differences in drug loading. At present, some improved swing tablet counters directly set a support structure on the material protection barrel. Although it has a certain function of supporting excess drugs, it is necessary to open holes on the original swing tablet counter, which makes unloading and replacement difficult. At the same time, the opened holes can only be used with a support structure of a specific height, and the use function is limited. For this reason, while solving the differences in drug filling in traditional swing tablet counters, optimizing the installation structure has become the main problem that needs to be solved at this stage.

[0035] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0036] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0037] This embodiment provides an improved swing chip counting machine assembly, referring to Figures 1 to 5, which includes a disc-shaped counting plate 1, and a mounting through hole A11 is provided in the center of the counting plate 1, which can provide installation space for other components later. The counting plate 1 is evenly provided with three groups of counting holes 12 that penetrate the counting plate 1 along the circumferential direction, and the number and size of single holes contained in each group of counting holes 12 are the same; in this embodiment, by selecting counting plates 1 with different single hole specifications, tablets of different specifications can be used for loading. In this embodiment, the single holes of each group of the counting holes 12 are arranged in 5 rows along the radial direction of the counting plate 1 and in 9 rows in the circumferential direction, and are distributed in a fan-shaped manner in space.

[0038] The improved swing counting machine assembly also includes a discharge tray 2 in the shape of a disc. The upper surface of the discharge tray 2 contacts the lower surface of the counting tray 1, the discharge tray 2 coincides with the axis of the counting tray 1, and the lower surface of the discharge tray 2 is tilted and fixed on an external support structure. The counting tray 1 forms a coaxial relative rotational motion with the discharge tray 2 when rotating axially. A mounting through hole B21 having the same diameter as the mounting through hole A11 is provided in the central part of the discharge tray 2. A material protection barrel A23 is provided along the circumference of the edge of the discharge tray 2, the top end of the barrel body of the material protection barrel A23 is kept horizontal, and the inner diameter of the material protection barrel A23 is the same as the outer diameter of the counting tray 1. The material protection barrel A23 is used to prevent tablets from falling into the external space during the operation of the tablet counting machine, and can limit the displacement of the counting tray 1 so that it can only perform axial rotational motion on the discharge tray 2. The discharge tray 2 is provided with a strip-shaped discharge hole 22 along its radial direction. During the coaxial relative rotation of the sheet counting tray 1 and the discharge tray 2 , the discharge hole 22 can be completely connected with each of the sheet counting holes 12 .

[0039] The improved swing chip counter assembly also includes a rotating transmission shaft 3, referring to Figure 5 The rotating transmission shaft 3 is cylindrical as a whole, and its diameter is the same as that of the mounting through hole A11. Its main body passes through the through space formed by the mounting through hole A11 and the mounting through hole B21. A card ledge 31 is provided on the top of the rotating transmission shaft 3 to limit the insertion depth of the rotating transmission shaft 3. At the same time, the bottom of the card ledge 31 is connected to the upper surface of the tablet counting disk 1, so that the movement relationship between the rotating transmission shaft 3 and the tablet counting disk 1 is always consistent. A card slot 32 is provided at the bottom of the rotating transmission shaft 3 for connecting a device that provides rotational power. A material protection barrel B33 is provided along the circumference of the edge of the card ledge 31 of the rotating transmission shaft 3. When used in conjunction with the material protection barrel A23, it can limit the tablets to always stay in the effective loading area.

[0040] The improved swing chip counter assembly also includes a positioning clamp assembly 4. Figure 3, the bottom of the positioning clamp assembly 4 is provided with a groove-shaped member 41, and positioning holes A411 are horizontally opened on the two side walls of the groove-shaped member 41. The top of the positioning clamp assembly 4 is provided with an insert 42 in the shape of an elongated thin sheet, and a sliding groove 421 is opened along the length direction of the insert 42. The positioning clamp assembly 4 also includes a U-shaped clip 43, which is used to fix the position of the positioning clamp assembly 4. The U-shaped clip 43 is clamped on the body of the protective barrel A23. The clamping legs on both sides of the U-shaped clip 43 are both curved, which can better achieve the fixing effect. The U-shaped clip 43 is provided with a protrusion 431 on the clamping leg located in the protective barrel A23, and the protrusion 431 is provided with a matching positioning bolt B4311, and the positioning bolt B4311 can slide in the sliding groove 421, so as to adjust the position of the U-shaped clip 43 on the insert 42. The side of the protrusion 431 away from the clamping leg is a plane and can overlap with the inserting piece 42, so as to facilitate the connection between the inserting piece 42 and the protrusion 431. A lever 432 is provided on the other clamping leg of the U-shaped clamping piece 43 for levering the U-shaped clamping piece 43 open.

[0041] The improved swing chip counter assembly also includes two brushes 5. Figure 4 , the two brushes 5 are radially arranged along the tablet counting disk 1, and the brush 5 includes a brush head 53, which can be slightly bent and has a length slightly longer than the distance between the material protection tube A23 and the material protection tube B33, so as to limit the movement range of the tablets in the unloading disk. The brush 5 also includes a brush handle 54, on which a positioning bolt A541 is provided, which can be matched with the positioning hole A411 to achieve the fixation between the brush 5 and the positioning clamp assembly 4. Since the height of the material protection tube A23 along the circumference of the discharge disk 2 is different, the position of the positioning bolt B4311 can be adjusted to make the brush 5 contact with the tablet counting disk 1. While brushing off the excess tablets in the tablet counting hole 12, the brush 5 is also used to limit the position of the tablets in the tablet counting disk 1 to prevent too many tablets from being accumulated in the tablet counting disk 1 and overflowing upward to the position of the discharge hole 22, resulting in a difference in the loading.

[0042] The improved swing tablet counting machine assembly also includes a material guide tube 6 with a smooth interior. The material guide tube 6 is in the shape of a stacked quadrangular pyramid, and tablets can slide into the material guide tube 6. A ring-shaped connecting piece 61 is provided on the top of the material guide tube 6 to achieve the connection between the material guide tube 6 and the discharge tray 2. The connecting piece 61 is fixed below the discharge hole 22, and the middle opening area can completely form a through space with the discharge hole 22. The bottom of the material guide tube 6 extends to the top of the external filling container, and the tangential dimension of the material guide tube 6 gradually decreases along the extension path. A plastic tube 62 with a smooth interior is provided at the bottom of the material guide tube 6. One end of the plastic tube 62 is sleeved on the bottom end of the discharge hole 22, and the other end can be adjusted according to the working conditions to introduce the tablets into the external filling container.

[0043] The improved swing chip counting machine assembly further includes a power source 7, which provides rotational kinetic energy for the rotation transmission shaft 3. The power source 7 is provided with an inclined body 71 on the top, and a protruding mounting support body 73 is provided on the inclined body 71, and the discharge tray 2 is fixed on the mounting support body 73. The inclined body 71 is also provided with a rotating shaft 72 protruding from its surface, and a key 721 matching the slot 32 is provided on the rotating shaft 72.

[0044] Before turning on the power source 7, select a sheet counting disk 1 with a suitable specification of sheet counting holes 12, and combine the brush 5 and the positioning clamp assembly 4. Adjust the position of the brush 5 along the circumferential direction of the sheet counting disk 1, wherein the brush A51 is set in the left area of ​​the sheet counting disk 1 and coincides with the horizontal line passing through the axis of the sheet counting machine; the brush B52 is set in the lower right area and forms a 45-degree angle with the horizontal line on the plane where the sheet counting disk 1 is located. Clamp the U-shaped clip 43 on the body of the material protection barrel A23, and adjust the position of the positioning bolt B4311 in the sliding groove 421 so that the bottom surface of the brush 5 contacts the upper surface of the sheet counting disk 1. At this time, the material protection barrel A23, the material protection barrel B33, the brush A51, and the brush B52 divide the sheet counting disk 1 into two areas a and b. The area with a relatively low horizontal position is area a, i.e., the loading area, and the external hopper is installed above this area; the other area is area b, i.e., the discharging area, and the discharging hole 22 is opened in this area. After adjusting the positions between the components, the external hopper is opened. Since the discharging tray 2 is tilted, the tablets will be accumulated in the loading area. At the same time, under the support of the brush 5, more tablets can be appropriately filled in the loading area to increase the area for the accumulated tablets, thereby making the charging process more complete.

[0045] After a portion of tablets are piled up in the loading area, the power source 7 is turned on, and the rotating shaft drives the rotating transmission shaft 3 to rotate counterclockwise, thereby driving the counting plate 1 to rotate counterclockwise. Since the brush A51 and the brush B52 are both fixed, the tablets will be subject to resistance during the axial rotation of the counting plate 1 and will always be retained in the loading area. The size of the counting hole 12 is slightly larger than the size of the tablets. When the counting hole 12 enters the loading area, under the action of the gravity of the piled tablets, the tablets at the bottom will enter the counting hole 12, and because friction will be generated when the tablets collide with each other during movement, the tablets that fall into the counting hole 12 will continuously adjust their positions and finally be completely placed in the counting hole 12.

[0046] In the process of counting tablets, in order to prevent tablets from falling off, the thickness of the counting hole 12 selected by the swinging tablet counting machine is often slightly larger than the thickness of the tablets, which may result in a situation where multiple tablets are stacked and stuck in one counting hole 12. In the absence of obstruction, static friction will be generated between the tablets in a single hole, and they may fall into the discharge hole 22 together with the rotation of the counting disc 1, resulting in overloading.

[0047] In view of this phenomenon, the filtering effect of the brush B52 can avoid it. When the tablet counting holes 12 pass through the brush B52, there is no extra space between the brush B52 and the tablet counting plate 1 for the tablets that exceed the plate surface to pass through. The brush B52 will retain the extra tablets on each of the tablet counting holes 12 in the loading area, reducing the tablet filling difference. When the tablet counting holes 12 are moved to a high place, the inclined installation of the tablet counting plate 1 can make the center of gravity of the stacked tablets fall outside the plate surface of the tablet counting plate 1, and the tablets automatically slide down under the action of gravity, further reducing the filling difference.

[0048] When the tablet counting hole 12 is connected with the discharge hole 22, the tablets will sequentially pass through the tablet counting hole 12, the discharge hole 22, the guide tube 6, and the plastic tube 62 and fall into the external filling container. At the same time, the tablet counting hole 12 continues to pass through the brush A51 and enters the loading area again to be loaded again. The tablet counting plate 1 has different specifications of tablet counting holes 12 to meet the filling requirements of different quantities and sizes of drugs.

[0049] In this embodiment, by adding a brush 5 and a positioning clamp assembly 4, it is possible to clean the excess tablets in the tablet counting hole 12, and the brush 5 and the positioning clamp assembly 4 are easy to install and operate, and can be flexibly installed in different positions according to working conditions. Compared with the improved method of the support structure directly fixed on the traditional swing tablet counting machine, the components in this embodiment are more convenient to disassemble and replace, and there is no need to open holes in the original structure. While solving the tablet stacking phenomenon in the traditional swing tablet counting machine, the installation structure is optimized.
