Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging technology, specifically to a tracked grain counting machine. Background Technology

[0002] Tracked pellet counting machines use a tracked line to count and transport pellets. After being transported to the feeding position, the pellets are generally fed by their own gravity. However, if the pellets are light and sticky, they are prone to sticking together when fed by their own gravity and cannot be successfully fed. In addition, the pellets will repeatedly jump and rotate in the feeding channel during the falling process, which will slow down the falling speed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tracked granule counting machine with a simple structure that can assist in the feeding of medicine granules and accelerate the feeding speed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A tracked pellet counting machine includes a circulating conveyor belt. The circulating conveyor belt includes a first sprocket and a second sprocket located at the bottom, a third sprocket located at the top, and a conveyor chain wound around the three sprockets. The conveyor chains between each sprocket are arranged at an angle. Multiple pellet counting mold groups are arranged at intervals on the conveyor chain. A feeding mechanism is provided between the first sprocket and the third sprocket. An air blowing mechanism and a feeding channel are respectively provided on the inner and outer sides of the conveyor chain at the second sprocket. The air blowing direction of the air blowing mechanism is the x-direction. The midline of the angle formed by the front end and the rear end of the conveyor chain of the second sprocket is y. The x and y are parallel, and the air blowing position is located on the side of the y-direction closer to the rear end of the conveyor chain. The pellet counting mold group is provided with a material receiving cavity and an air channel communicating with the material receiving cavity.

[0006] As a further improvement to the above technical solution:

[0007] The tracked counting machine further includes a first detection mechanism located between the third sprocket and the second sprocket, and a second detection mechanism located between the first sprocket and the second sprocket. The first detection mechanism is used to detect whether the counting die group carries a qualified number of pills before entering the feeding channel, and the second detection mechanism is used to detect whether there are any pills that were not successfully fed after the counting die group passes through the feeding channel.

[0008] Below the feeding channel is a guide channel for docking with the bottle body. Below the guide channel are a filling and bottling area and a waste collection area. The tracked counting machine also includes a moving drive mechanism, which drives the guide channel to move horizontally between the filling and bottling area and the waste collection area. The moving drive mechanism is electrically connected to the first detection mechanism.

[0009] The tracked pellet counter also includes a third detection mechanism, which is used to detect whether the material in the feeding channel has entered the guide channel.

[0010] The guide channel is connected to a vibration drive mechanism for driving the guide channel to vibrate during material feeding.

[0011] The feeding mechanism includes a feeding bin that extends from above the first sprocket to above the third sprocket and is connected to a set of multiple molds. The feeding bin has an opening at one end near the third sprocket, and a blower mechanism is provided between the opening and the set of multiple molds. The blowing direction of the blower mechanism is opposite to the conveying direction of the set of multiple molds.

[0012] A brush wheel is provided on the side of the feeding bin near the third sprocket. The brush wheel is used to brush away excess particles in the mold assembly.

[0013] Static electricity elimination mechanisms are provided on the feeding hopper and between the third sprocket and the second sprocket.

[0014] The feeding hopper is also equipped with a vibration mechanism.

[0015] The tracked grain counting machine also includes a human-machine interface and a warning light, which is used to issue a prompt in case of an abnormality.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The tracked counting machine disclosed in this utility model has a counting mold assembly that is fed by the feeding mechanism and then conveyed backward. After reaching the second sprocket, the material chamber begins to tilt downward, and the medicine granules in the material chamber fall down by their own gravity. After continuing to run to the blowing mechanism, the blowing mechanism blows air into the air passage to help the medicine granules fall into the feeding channel.

[0018] In this tracked granule counter, the blowing direction (x) of the air blowing mechanism is parallel to the centerline (y), and the air blowing position is located on the side of the rear conveyor chain closer to the centerline (y). The air blowing method is intermittent, meaning that the counting molds in the counting mold group tilt downwards before blowing air to assist the granules in falling downwards, rather than blowing air upwards. This ensures that the granules can fall smoothly into the feeding channel below, preventing lighter, more viscous granules from failing to fall successfully under their own weight. At the same time, the air blowing mechanism can accelerate the falling speed of the granules, reducing the repeated jumping and rotating of the granules in the feeding channel, thereby reducing the adhesion of granules to the feeding channel during filling and improving the accuracy of counting and filling.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Figures 1 to 3This invention illustrates an embodiment of the present invention. The tracked counting machine of this embodiment includes a circulating conveyor belt 1. The circulating conveyor belt 1 includes a first sprocket 11 and a second sprocket 12 located below, a third sprocket 13 located above, and a conveyor chain 14 wound around the three sprockets. The conveyor chains 14 between each sprocket are arranged at an angle. Multiple counting mold groups 2 are arranged at intervals on the conveyor chains 14. A feeding mechanism 3 is provided between the first sprocket 11 and the third sprocket 13. An air blowing mechanism 6 and a feeding channel 4 are respectively provided on the inner and outer sides of the conveyor chain 14 at the second sprocket 12. The air blowing direction of the air blowing mechanism 6 is the x-direction. The midline of the angle formed by the front end and the rear end of the conveyor chain 14 of the second sprocket 12 is y. x and y are parallel, and the air blowing position is located on the side of y closer to the rear end of the conveyor chain 14. The counting mold group 2 is provided with a material receiving cavity 21 and an air channel 22 communicating with the material receiving cavity 21.

[0028] In this tracked counting machine, the counting mold group 2 is fed by the feeding mechanism 3 and then conveyed backward. After reaching the second sprocket 12, the material chamber 21 begins to tilt downward. The medicine particles in the material chamber 21 fall by their own gravity and continue to run to the air blowing mechanism 6. The air blowing mechanism 6 blows air into the air passage 22 to help the medicine particles fall into the feeding channel 4.

[0029] like Figure 3 As shown, in this tracked counting machine, the blowing direction x of the air blowing mechanism 6 is parallel to the centerline y, and the air blowing position of the air blowing mechanism 6 is located on the side of y close to the rear conveyor chain 14. The air blowing method is intermittent air blowing, that is, the counting mold in the counting mold group 2 tilts downward and then blows air to assist the medicine to fall downward, rather than blowing air upward, to ensure that the medicine can fall smoothly into the feeding channel 4 below, avoiding the failure of the lighter and more viscous medicine to fall successfully by its own weight. At the same time, the air blowing mechanism 6 can accelerate the falling speed of the medicine and reduce the repeated jumping and rotating of the medicine in the feeding channel 4, thereby reducing the adhesion of the medicine to the feeding channel 4 during filling and improving the accuracy of counting and filling.

[0030] In this embodiment, the tracked counting machine further includes a first detection mechanism 7 located between the third sprocket 13 and the second sprocket 12, and a second detection mechanism 5 located between the first sprocket 11 and the second sprocket 12. The first detection mechanism 7 is used to detect whether the counting die group 2 carries a qualified number of pills before entering the feeding channel 4. The second detection mechanism 5 is used to detect whether there are any pills left in the counting die group 2 after passing through the feeding channel 4 that were not successfully fed. The first detection mechanism 7 can detect whether the feeding of the counting die group 2 is qualified. If the number of pills in the counting die group 2 is exactly the set number, the feeding is qualified and meets the bottling conditions. If the number of pills in the counting die group 2 is more or less than the set number, the feeding is unqualified and does not meet the bottling conditions. The second testing agency 5 checks whether there are still undischarged particles in the counting mold group 2 after discharging through the feeding channel 4. If particles are found to remain in the counting mold group 2, it indicates that the particles in the counting mold group 2 have not completely fallen into the feeding channel 4, which will lead to a reduction in the actual amount of bottling particles and unqualified discharging. If no particles are found to remain in the counting mold group 2, the discharging is qualified.

[0031] In this embodiment, a guide channel 8 for docking with the bottle body is provided below the feeding channel 4. A filling and bottling area and a waste collection area are provided below the guide channel 8. The tracked counting machine also includes a moving drive mechanism 9, which drives the guide channel 8 to move horizontally between the filling and bottling area and the waste collection area. The moving drive mechanism 9 is connected to the first detection mechanism 7. Specifically, both the feeding channel 4 and the guide channel 8 are funnel-shaped, and the inlet of the feeding channel 4 is larger than the inlet of the guide channel 8, which can pass through the particles falling from the counting mold group 2. The outlet of the guide channel 8 is the same size as the bottle opening of the bottle to be filled, which plays a role in guiding the filling. The outlets of the feeding channel 4 and the guide channel 8 are staggered in the horizontal direction.

[0032] The feeding channel 4 connects to the bottle via the guide channel 8 to facilitate bottle filling. Before filling, the bottle is transported to the filling and bottling area to await filling. If the first detection mechanism 7 detects that the number of particles in the counting mold group 2 is qualified, the moving drive mechanism 9 drives the guide channel 8 to move to the filling and bottling area, so that the outlet of the guide channel 8 connects with the bottle mouth of the bottle to be filled, and waits for bottling. If the first detection mechanism 7 detects that the number of particles in the counting mold group 2 is unqualified, the moving drive mechanism 9 drives the guide channel 8 from the filling and bottling area to the waste collection area, so that the outlet of the guide channel 8 is offset from the bottle mouth of the bottle to be filled and connects with the waste collection container to collect waste. The unqualified bottle at this time can be rejected in the subsequent bottle conveying process.

[0033] In this embodiment, the tracked granule counter further includes a third detection mechanism 10, which is used to detect whether the material in the feeding channel 4 has entered the guide channel 8. The third detection mechanism 10 detects whether all the granules in the feeding channel 4 have entered the guide channel 8. If no granules remain in the feeding channel 4, the bottling conditions are met. If granules remain in the feeding channel 4, the amount of bottling granules will be reduced, and the bottling conditions will not be met.

[0034] In this embodiment, the first detection mechanism 7, the second detection mechanism 5, and the third detection mechanism 10 detect the qualification of feeding, unloading, and bottling to improve the accuracy of the number of bottling particles and ensure the product qualification rate. If the first detection mechanism 7 fails to detect the failure, the guide channel 8 needs to be moved for rejection. If the second detection mechanism 5 and the third detection mechanism 10 fail to detect the failure, the machine needs to be stopped or other qualification compensation processes need to be performed to further improve the accuracy of subsequent particle counting and filling.

[0035] In this embodiment, the guide channel 8 is connected to a vibration drive mechanism 15 for driving the guide channel 8 to vibrate and discharge material. Since the outlet of the guide channel 8 is small, the vibration drive mechanism 15 can reduce the blockage of particles at the outlet of the guide channel 8 and help the particles in the guide channel 8 fall smoothly into the bottle.

[0036] In this embodiment, the feeding mechanism 3 includes a feeding bin 31, which extends from above the first sprocket 11 to above the third sprocket 13 and is connected to the counting mold group 2. The feeding bin 31 has an opening 311 at one end near the third sprocket 13. A blower mechanism 32 is provided between the opening 311 and the counting mold group 2, and the blowing direction of the blower mechanism 32 is opposite to the conveying direction of the counting mold group 2. The feeding bin 31 extending from above the first sprocket 11 to above the third sprocket 13 improves feeding efficiency. The blower mechanism 32 blowing in the opposite direction to the conveying direction of the counting mold group 2 can blow excess adhered particles back to the feeding bin 31, ensuring the qualified quantity of particles in the counting mold group 2.

[0037] In this embodiment, a brush wheel 33 is provided on the side of the feeding bin 31 near the third sprocket 13. The brush wheel 33 is used to brush away excess particles in the counting mold group 2. The rotation direction of the brush wheel 33 is also opposite to the conveying direction of the counting mold group 2. The rotation of the brush wheel 33 brushes away the adhering excess particles, and the brushed particles return to the feeding bin 31 under the blowing action of the blower mechanism 32.

[0038] In this embodiment, static elimination mechanisms are provided on the feeding hopper 31 and between the third sprocket 13 and the second sprocket 12. These static elimination mechanisms (not shown in the figure) reduce adhesion between particles and between particles and the mold plate, further improving the accuracy of feeding, unloading, and bottling processes.

[0039] In this embodiment, a vibration mechanism 16 is also provided on the feeding hopper 31 to further prevent the particles in the feeding hopper 31 from sticking together and clumping.

[0040] In this embodiment, the tracked grain counting machine also includes a human-machine interface and a warning light. The warning light is used to issue a prompt in case of abnormality. The operator can set the operating parameters through the human-machine interface (not shown in the figure). If the second detection mechanism 5 and the third detection mechanism 10 fail the detection, the warning light (not shown in the figure) will emit an audible and visual prompt to remind the operator to stop the machine for handling.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
