[0002] When counting and filling pills, vibration discharging is generally adopted. Through vibration, the pills are arranged in a certain pattern, and then the neatly arranged pills are counted and filled.

[0003] The existing feeding device, such as the dripping pill granule counting and filling device with the patent number CN200410014466.3, discloses that a ring-shaped conveyor belt is used to convey the dripping pills, and granule counting holes are used to count the number of dripping pills. Finally, the pills are bottled through a filling funnel. However, the feeding device has the following problems:

[0004] 1) If the feed particles are sticky, there will be problems of adhesion and an increase in the number of particles, resulting in inaccurate granule counting and bottling.

[0005] 2) Bottles with inaccurate bottling cannot be detected and rejected, affecting the bottling qualification rate.

[0006] 3) When feeding and bottling, the sticky particles cannot fall automatically under the action of gravity, resulting in a decrease in the number of particles and inaccurate bottling. Content of the Utility Model

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a crawler type granule counting machine that improves the accuracy of the number of granule bottles and ensures the product qualification rate.

[0008] To solve the above technical problems, the utility model adopts the following technical solutions:

Along the conveying direction of the circulating conveyor belt, a feeding mechanism, a third detection mechanism, a first detection mechanism, a transition channel and a second detection mechanism are sequentially arranged. A blanking channel for docking with a bottle body is arranged below the transition channel. The third detection mechanism is used to detect whether the granule counting die set carries a qualified number of particles before entering the transition channel. The first detection mechanism is used to detect whether the particles in the transition channel enter the blanking channel. The second detection mechanism is used to detect whether there are still particles that have not been successfully blanked in the granule counting die after blanking through the transition channel.

[0010] As a further improvement of the above technical solution:

[0011] Below the blanking channel are provided a filling and bottling area and a waste collection area. The crawler type granule counting machine further includes a moving drive mechanism, which is used to drive the blanking channel to translate between the filling and bottling area and the waste collection area. The third detection mechanism is connected to the moving drive mechanism.

[0012] The circulating conveyor belt includes a first sprocket and a second sprocket provided below, a third sprocket provided above, and a conveyor chain wound around the three sprockets. The granule counting die set is arranged on the conveyor chain. The conveyor chain between each sprocket is inclined. The feeding mechanism is located between the first sprocket and the third sprocket. The third detection mechanism and the first detection mechanism are located between the third sprocket and the second sprocket. The transition channel is located below the second sprocket. The second detection mechanism is located between the second sprocket and the first sprocket.

[0013] The feeding mechanism includes a feeding bin, which extends from above the first sprocket to above the third sprocket and is communicated with the granule counting die set. An opening is provided at one end of the feeding bin close to the third sprocket. A blowing mechanism is provided between the opening and the granule counting die set. The blowing direction of the blowing mechanism is opposite to the conveying direction of the granule counting die set.

[0014] A brush wheel is provided on one side of the feeding bin close to the third sprocket, and the brush wheel is used to brush off the excess granules in the granule counting die set.

[0015] Static eliminators are provided on the feeding bin and between the third sprocket and the second sprocket.

[0016] The blanking channel is connected with a jitter drive mechanism for driving the blanking channel to jitter and discharge materials.

[0017] A vibration mechanism is provided on the feeding bin.

[0018] The crawler type granule counting machine further includes a knocking and discharging mechanism and a blowing and discharging mechanism, and both the knocking and discharging mechanism and the blowing and discharging mechanism are used to assist the granules in the granule counting die set to fall into the blanking channel.

[0019] The crawler type granule counting machine further includes a human-machine interaction interface and a warning lamp, and both the first detection mechanism and the second detection mechanism are connected to the warning lamp.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] The counting die set of the crawler-type granule counter disclosed by the present utility model can carry a fixed number of granules, thereby realizing counting. It is fed through the feeding mechanism under the conveyance of the circulating conveyor belt, and then the third detection mechanism detects the counting die set to check whether the counting die set carries a qualified number of granules. If the number of granules in the counting die set is exactly the set number, the feeding is qualified and meets the bottling condition. If the number of granules in the counting die set is more or less than the set number, the feeding is unqualified and does not meet the bottling condition. Then, after being conveyed to the discharging position, it falls into the transition channel by its own gravity, and finally discharges and fills through the discharging channel. During the discharging process, the first detection mechanism detects whether all the granules in the transition channel enter the discharging channel. If it is detected that there are no remaining granules in the transition channel, it meets the bottling condition. If it is detected that there are still remaining granules in the transition channel, it will cause a reduction in the number of granules for bottling and does not meet the bottling condition. After the discharging is completed, the second detection mechanism detects whether there are still granules that have not been successfully discharged in the counting die after discharging through the transition channel. If it is detected that there are still remaining granules in the counting die, it indicates that the granules in the counting die have not completely fallen into the transition channel, which will cause a reduction in the number of granules for bottling and the discharging is unqualified. If it is detected that there are no remaining granules in the counting die, the discharging is qualified. In summary, only when the third detection mechanism for detecting whether the feeding is qualified, the first detection mechanism for detecting whether the bottling is qualified, and the second detection mechanism for detecting whether the discharging is qualified all detect qualified, can it be recognized as a qualified product. If any one of the detection mechanisms detects unqualified, it is an unqualified product.

[0022] During the feeding, discharging, and filling processes of the crawler-type granule counter of the present utility model, the third detection mechanism, the second detection mechanism, and the first detection mechanism are respectively set to detect the qualification of feeding, discharging, and bottling, improving the accuracy of the number of granules for bottling and ensuring the product qualification rate.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality of" is two or more unless otherwise specifically defined.

[0029] In the present utility model, unless otherwise clearly specified and defined, the terms "assembled", "connected", "joined", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] Figure 1 and Figure 2 Fig. shows an embodiment of the present utility model. The crawler-type granule counting machine of this embodiment includes a circulating conveyor belt 1 and a plurality of granule counting die sets 2 arranged at intervals on the circulating conveyor belt 1. A feeding mechanism 3, a third detection mechanism 9, a first detection mechanism 4, a transition channel 5, and a second detection mechanism 6 are successively arranged along the conveying direction of the circulating conveyor belt 1. A blanking channel 16 for docking with a bottle body is arranged below the transition channel 5. The third detection mechanism 9 is used to detect whether the granule counting die set 2 carries a qualified number of particles before entering the transition channel 5. The first detection mechanism 4 is used to detect whether the particles in the transition channel 5 enter the blanking channel 16. The second detection mechanism 6 is used to detect whether there are still particles that have not been successfully blanked in the granule counting die set 2 after blanking through the transition channel 5.

[0031] The counting die set 2 of the crawler-type counting machine can carry a fixed number of particles, thereby realizing counting. The particles are loaded through the loading mechanism 3 under the transportation of the circulating conveyor belt 1, and then the third detection mechanism 9 detects the counting die set 2 to detect whether the counting die set 2 carries a qualified number of particles. If the amount of particles in the counting die set 2 is exactly the set amount, the loading is qualified and meets the bottling conditions. If the amount of particles in the counting die set 2 is more or less than the set amount, the loading is unqualified and does not meet the bottling conditions. Then, after being transported to the unloading position, it falls into the transition channel 5 by its own gravity, and finally is unloaded and filled through the unloading channel 16. During the unloading process, the first detection mechanism 4 detects whether all the particles in the transition channel 5 have entered the unloading channel 16. If it is detected that there are no particles remaining in the transition channel 5, it meets the requirements. If it is detected that there are still residual particles in the transition channel 5, the amount of bottling particles will be reduced, and the bottling conditions will not be met. After the unloading is completed, the second detection mechanism 6 detects whether there are still unsuccessfully unloaded particles in the counting mold group 2 after unloading through the transition channel 5. If it is detected that there are still residual particles in the counting mold group 2, it indicates that the particles in the counting mold group 2 have not completely fallen into the transition channel 5, which will lead to a reduction in the amount of bottling particles and unloading is unqualified. If it is detected that there are no residual particles in the counting mold group 2, the unloading is qualified. In summary, only when the third detection mechanism 9 for detecting whether the loading is qualified, the first detection mechanism 4 for detecting whether the bottling is qualified and the second detection mechanism 6 for detecting whether the unloading is qualified are all qualified can it be identified as a qualified product. If one detection mechanism detects unqualified, all are unqualified products.

[0032] During the unloading and filling process of the crawler-type pellet counting machine, the third detection mechanism 9, the second detection mechanism 6 and the first detection mechanism 4 are respectively provided to detect the eligibility of loading, unloading and bottling, thereby improving the accuracy of the number of bottled pellets and ensuring the product qualification rate.

[0033] Further preferably, in this embodiment, the transition channel 5 and the discharge channel 16 are both funnel-shaped, and the entrance of the transition channel 5 is larger than the entrance of the discharge channel 16, which can transition the particles falling from the several pellet mold groups 2, and the outlet of the discharge channel 16 is consistent with the size of the bottle mouth of the bottle to be filled, which plays a role in guiding the filling, and the outlets of the transition channel 5 and the discharge channel 16 are staggered in the horizontal direction.

[0034] In this embodiment, a filling and bottling area and a waste collection area are provided below the feed channel 16. The crawler-type pellet counting machine further includes a mobile drive mechanism 8, which is used to drive the feed channel 16 to translate between the filling and bottling area and the waste collection area. A third detection mechanism 9 is connected to the mobile drive mechanism 8. Before filling, the bottles are transported to the filling and bottling area to wait for filling. If the third detection mechanism 9 detects that the number of pellets in the pellet counting die set 2 is qualified, the mobile drive mechanism 8 drives the feed channel 16 to move to the filling and bottling area, so that the outlet of the feed channel 16 docks with the bottle mouth of the bottle to be filled, and waits for bottling. If the third detection mechanism 9 detects that the number of pellets in the pellet counting die set 2 is unqualified, the mobile drive mechanism 8 drives the feed channel 16 from the filling and bottling area to the waste collection area, so that the outlet of the feed channel 16 is staggered with the bottle mouth of the bottle to be filled and docks with a waste collection container to collect waste. The unqualified bottles at this time can be discarded during the subsequent bottle conveying process.

[0035] In this embodiment, the circulating conveyor belt 1 includes a first sprocket 11 and a second sprocket 12 located at the bottom, a third sprocket 13 located at the top, and a conveyor chain 14 wound around the three sprockets. The counting die set 2 is located on the conveyor chain 14, and the conveyor chains 14 between the sprockets are arranged at an angle. The loading mechanism 3 is located between the first sprocket 11 and the third sprocket 13. The third detection mechanism 9 and the first detection mechanism 4 are located between the third sprocket 13 and the second sprocket 12. The transition channel 5 is located below the second sprocket 12, and the second detection mechanism 6 is located between the second sprocket 12 and the first sprocket 11. This reduces the chance of particles falling after loading and before unloading, improves the accuracy of counting and filling, and allows the particles to fall by their own gravity after reaching the transition channel 5, saving power and having a compact and reasonable structure.

[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 die set 2. An opening 311 is provided at one end of the feeding bin 31 near the third sprocket 13. A blower mechanism 32 is provided between the opening 311 and the counting die set 2. The blowing direction of the blower mechanism 32 is opposite to the conveying direction of the counting die set 2. The feeding bin 31 extends from above the first sprocket 11 to above the third sprocket 13, which can improve the feeding efficiency. The blowing direction of the blower mechanism 32 is opposite to the conveying direction of the counting die set 2, which can blow the excess particles stuck to the feeding bin 31 back to ensure the qualified number of particles in the counting die set 2.

[0037] In this embodiment, a brush wheel 33 is provided on the side of the loading bin 31 near the third sprocket 13. The brush wheel 33 is used to brush away excess particles in the counting die set 2. The rotation direction of the brush wheel 33 is also opposite to the conveying direction of the counting die set 2. The brush wheel 33 rotates to brush away excess particles that are adhered to the counting die set 2. The brushed particles are then blown back to the loading bin 31 by the air blower mechanism 32.

[0038] In this embodiment, static eliminators 10 are provided both on the feeding bin 31 and between the third sprocket 13 and the second sprocket 12. The static eliminators 10 can reduce the adhesion between particles and between particles and the die plate, further improving the accuracy in the processes of feeding, discharging, and bottling.

[0039] In this embodiment, a jitter driving mechanism 7 for driving the jitter discharging of the discharging channel 16 is connected to the discharging channel 16. Since the outlet of the discharging channel 16 is small, the jitter driving mechanism 7 can reduce the blockage of particles at the outlet of the discharging channel 16 and assist the particles in the discharging channel 16 to smoothly fall into the bottle body.

[0040] In this embodiment, a vibration mechanism 15 is provided on the feeding bin 31. Further avoid the adhesion of particles in the feeding bin 31.

[0041] In this embodiment, the crawler-type grain counting machine further includes a knocking and discharging mechanism 17 and a blowing and discharging mechanism 18, and both the knocking and discharging mechanism 17 and the blowing and discharging mechanism 18 are used to assist the particles in the grain counting die set 2 to fall into the discharging channel 16. Avoid the situation where particles cannot successfully fall due to their own gravity, reduce the adhesion between particles and the die plate, further improve the accuracy in the processes of discharging and bottling, and at the same time can also accelerate the discharging speed and improve the filling speed.

[0042] In this embodiment, the crawler-type grain counting machine further includes a human-machine interface 19 and a warning lamp 20, and both the first detection mechanism 4 and the second detection mechanism 6 are connected to the warning lamp 20. The operator can set the operating parameters through the human-machine interface 19. If the first detection mechanism 4 and the second detection mechanism 6 detect unqualified, the warning lamp 20 gives an audible and visual prompt to remind the operator to stop the machine for processing.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the above-disclosed technical content, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change, and modification made to the above embodiments according to the technical essence of the present utility model without departing from the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
