In this embodiment, the vision monitoring system 5 includes cameras, and a plurality of cameras are arranged above the brush roller 4 at equal intervals, and the phenomenon of particle lacking in the particle counting holes in the particle counting strips is monitored in real time.

The rotating shaft of the chain wheel 11 is also sleeved with a cam mechanism 6, the cam mechanism 6 comprises a rotating wheel 13, a cam 18 and an ejector plate 17, and the cam 18 is fixedly arranged on the filling device. The rotating wheel 13 and the chain wheel 11 rotate coaxially and synchronously, the rotating wheel 13 is provided with guide grooves 10, as shown in fig. 9, the direction of the guide grooves 10 is radial, the tail end of the guide grooves is positioned on the circumferential surface of the rotating wheel 13, and a plurality of guide grooves 10 are arranged on the circumference at equal intervals and are radial; the cam 18 is arranged outside the rotating wheel, the cam 18 is provided with a cam groove 14, and the end part of the ejector plate 17 is provided with a roller 15; the roller 15 penetrates the guide groove 10 and can roll in the cam groove 14; the thimble plate 17 is further provided with thimbles 16, the positions of the thimbles 16 correspond to the positions of the grain counting holes on the grain counting strips 3 one by one, and the outer diameter of the thimbles 16 is slightly smaller than the aperture of the grain counting holes, so that the thimbles 16 can penetrate through the grain counting holes.

Sorting mechanism 7 includes letter sorting passageway 9, lower whirl baffle 21 and last whirl baffle 22, and lower whirl baffle 21 is connected with revolving cylinder 33, and revolving cylinder 33 drive lower whirl baffle 21 is rotatory along its pivot, and last whirl baffle 22 is connected with letter sorting cylinder 23, and rotatory baffle 22 is rotatory along its pivot in the drive of letter sorting cylinder 23.

The filling mechanism 8 comprises a filling cylinder 26, a filling inlet 29 of the filling cylinder 26 is communicated with the sorting discharge port 20, a filling outlet 30 of the filling cylinder 26 is communicated with a small bottle opening used for filling dripping pills on the production line, a baffle 28 is arranged in the filling cylinder 26, the filling cylinder 26 is also connected with a filling cylinder 24, and the filling cylinder 24 drives the filling cylinder 26 to move up and down.

The filling cylinder 26 is further connected with a vibrator 25 and a blowing head 27, and the blowing head 27 is communicated with the inner cavity of the filling cylinder 26. The lower part of the inner cavity of the filling cylinder 26 is in an inverted cone shape, a filling outlet 30 at the bottom of the filling cylinder 26 is the end point of the inverted cone shape, and the size of the filling outlet 30 is slightly larger than the inner diameter of the bottle mouth of the small bottle, so that the bottle mouth is pressed, and blanking is carried out.

The counting strip 3 is also provided with flanges 34 on both sides. The flanges 34 are fixedly arranged on the filling device and are positioned at two sides of the plurality of strips 3, so that the dripping pills can be prevented from splashing out of the filling device. The grain counting plates at two end parts of the grain counting strip 3 are zero grain counting plates 31, and the other grain counting plates are middle grain counting plates 32. Wherein, the zero-number counting plate 31 plays a role of starting counting without filling dripping pills; the middle tablet counting plate 32 is filled with pills.

When the machine works, the chain wheel 11 rotates anticlockwise, and the counting strips 3 filled with the dropping pills move obliquely upwards. Meanwhile, the brush roller 4 above the chain 2 rotates anticlockwise to sweep the dropping pills which do not enter the counting holes down, and the dropping pills return to the guide sliding plate 12 and then enter the counting strips 3 again. The pill particles in the particle counting bar 3 move to the cam mechanism 6 along with the rotation of the chain 2.

In operation, as shown in fig. 9-16, the sprocket 11 and the runner 13 rotate synchronously, the cam 18 is fixed, the sprocket 11 drives the plurality of strips 3 to move, and the runner 13 drives the ejector plate 17 to move. The rollers 15 at both ends of the ejector plate 17 pass through the guide grooves 10 and are stopped in the cam grooves 14. As the sprocket 11 and the runner 13 rotate, the roller 15 rolls along the cam groove 14, and the sprocket 11 and the runner 13 complete one movement cycle of the roller 15 along the cam groove 14 for each rotation. The outside diameter of the thimble 16 is slightly smaller than the aperture of the counting holes, so that the thimble on the thimble plate can gradually eject the dripping pills in the counting holes in the movement process of the thimble plate by virtue of the shape of the cam groove 14, when the roller 15 rolls to the position where the cam groove 14 protrudes, as shown in fig. 16, the thimble 16 can just penetrate through the counting holes to eject the dripping pills in the counting holes out of the counting holes, so that the dripping pills orderly and continuously enter the sorting mechanism 7.

During working, the vision monitoring system 5 monitors whether a particle lack phenomenon exists in the particle counting holes, if the particles do not exist in the particle counting strips and the particle number in the sorting mechanism 7 does not meet the requirement of filling number, the lower rotating baffle 21 of the sorting mechanism 7 is positioned in the position in the figure 21, and the dropping pills are stored in the sorting channel 9; if no granules are in the counting strips and the quantity of the granules in the sorting mechanism meets the requirement of the filling quantity, the lower rotary baffle 21 of the sorting mechanism 7 moves to the position in the figure 22, and the dripping pill granules freely fall down and enter the filling mechanism 8; if the counting strips have a particle lack condition, the lower rotating baffle 21 and the upper rotating baffle 22 of the sorting mechanism 7 move to the positions in fig. 23, the upper rotating baffle 22 rotates to the upper end to abut against the inner wall of the filling cylinder 26, the upper rotating baffle 22 forms a waste channel, and at the moment, the dropping pill particles in the particle lack counting strips do not enter the sorting mechanism 7 temporarily; subsequently, when the ejector pins 16 eject out the pill particles in the above-mentioned lacking pieces, the pill particles will directly flow out through the waste passage after entering the sorting inlet 19, and are recovered.

In operation, before the pill particles enter the filling mechanism 8, the filling cylinder 26 moves downward to the filling outlet 30 and presses against the mouth of the vial just under the action of the filling cylinder 24, and the pill particles falling from the sorting outlet 20 enter the filling cylinder 26 through the filling inlet 29. Under the blowing action of the blowing head 27 and the vibration action of the vibrator 25, the dropping pill particles fall down in an accelerated way; meanwhile, the baffle 28 prevents the dropping pill particles from spirally falling on the conical surface of the inverted conical cavity of the filling cylinder 26, and the dropping of the dropping pill particles is accelerated. Finally, the dripping pill particles flow out of the filling outlet 30 into a vial to complete filling.
