[0024] Please refer to Figures 1 to 3 , the following further describes the present utility model with reference to the drawings and embodiments. The embodiments of the present application disclose a drug sorting device based on machine recognition (hereinafter referred to as drug sorting device), including a drug feeder 100 and a drug recognition part 400:

[0025] The discharge port of the medicine feeder 100 is connected to one end of a transparent medicine delivery tube 300 through an inclined downward outlet chute 200. A rotating shaft 310 is perpendicularly arranged to the central axis on one side of the transparent medicine delivery tube 300 deviating from the central axis. A plurality of medicine retaining plates 320 are arranged in a circumferential array around the rotating shaft 310. An adjacent pair of the medicine retaining plates 320 forms a medicine retaining chamber 330. At least one pair of medicine identification members 400 are arranged on the transparent medicine delivery tube 300. The medicine identification members 400 are arranged at one end away from the rotating shaft 310 along the medicine moving direction. The other end of the transparent medicine delivery tube 300 is connected to a first medicine outlet tube 340 and a second medicine outlet tube 350 in a Y-shaped manner. A medicine delivery valve is arranged at the connection of the transparent medicine delivery tube 300, the first medicine outlet tube 340 and the second medicine outlet tube 350. The medicine delivery valve is used to connect the transparent medicine delivery tube 300 with the first medicine outlet tube 340 or the second medicine outlet tube 350. Among them, the discharge port of the medicine feeder 100 is connected to the transparent medicine delivery tube 300 through an inclined downward outlet chute 200, which helps the medicine to smoothly and steadily slide into the transparent medicine delivery tube 300 under the action of gravity. The transparent medicine delivery tube 300 is located below the outlet chute 200 and is a vertical transparent pipe for guiding the continuous downward movement of the medicine. A rotating shaft 310 is arranged on one side deviating from the central axis of the transparent medicine delivery tube 300. The medicine retaining plates 320 are evenly arranged in a circumferential array around the rotating shaft 310. A medicine retaining chamber 330 is formed between an adjacent pair of the medicine retaining plates 320 for temporarily storing the medicine. The medicine retaining chamber 330 is not arranged on the central axis of the transparent medicine delivery tube 300 but deviates from the central axis of the medicine delivery tube. And the size of each medicine retaining chamber 330 is only enough for storing one medicine, so as to help control the medicine to fall one by one instead of continuously. At the medicine outlet end of the medicine retaining chamber 330, that is, below the medicine retaining chamber 330, at least one pair of medicine identification members 400 are arranged. The medicine identification members 400 are relatively arranged on or on both sides of the transparent medicine delivery tube 300 for identifying the characteristics of the falling medicine, such as size, shape, color, integrity, etc. For example, if it is a capsule medicine, only two medicine identification members 400 are needed at the front and back. If the medicine is in a cake shape, four medicine identification members 400 are needed. By installing the medicine identification members 400 in the four positive directions of the transparent medicine delivery tube 300, the falling medicine can be detected and identified without dead angles. The end of the transparent medicine delivery tube 300 is connected to the first medicine outlet tube 340 and the second medicine outlet tube 350. The transparent medicine delivery tube 300, the first medicine outlet tube 340 and the second medicine outlet tube 350 are interconnected to form a Y-shaped channel. A medicine delivery valve is arranged at the connection of the first medicine outlet tube 340 and the second medicine outlet tube 350. The medicine delivery valve is used to connect the transparent medicine delivery tube 300 with the first medicine outlet tube 340 or the second medicine outlet tube 350, so as to control the flow direction of the medicine to different medicine outlet tubes.

[0026] In the specific work, the finished medicines are put into the medicine feeder 100. After the medicines slide into the inclined outlet slide 200 from the discharge port of the feeder, they enter the transparent medicine delivery tube 300 along the outlet slide 200 and fall freely into the medicine retention chamber 330. The medicine retention plate 320 of the medicine retention chamber 330 rotates downward under the gravity of the medicines to continue to transport the medicines downward. During the falling process, the medicine identification element 400 will identify the integrity of the medicines, because the medicines may be broken, bumped, squeezed, etc. during the production or transportation process. Incomplete medicines, especially tablets, are more prone to incomplete defects, and incomplete tablets may cause reduced or insufficient efficacy, thereby increasing medical risks. After passing through the medicine identification part 400, the medicine continues to fall. When it reaches the intersection of the first medicine outlet pipe 340 and the second medicine outlet pipe 350, the medicine discharge valve opens or closes the transparent medicine discharge pipe 300 and connects the first medicine outlet pipe 340 or the second medicine outlet pipe 350 according to the recognition result of the medicine identification part 400, so that the medicine enters the correct channel and the medicine is sorted.

[0027] By using the above-mentioned drug sorting equipment, the drugs pass through the drug retention chamber 330, causing the drugs to fall one by one, providing a favorable time for the subsequent drug identification piece 400. After identification, the drugs are diverted through the guide plate 510, thereby improving the accuracy of drug detection, thereby ensuring that the drugs will not be missed, ensuring the quality of the drugs while improving production efficiency.

[0028] It should be noted that the medicine feeder 100 can be a medicine feeder 100 available on the market, such as a tablet counting and packaging machine, a vibration plate automatic feeder, a tablet centrifugal feeder, a fully automatic capsule, tablet, pill packaging machine or dispensing machine, etc.

[0029] To further improve the accuracy and reliability of detection, the drug identification element 400 includes any one of a laser scanner and a camera. The laser scanner and the camera can be used in combination or separately. The laser scanner is used to obtain the three-dimensional shape and contour data of the product through non-contact scanning, without direct contact with the drug, to avoid cross contamination, and can work in harsh environments and is not affected by light conditions; the camera can be used to detect the appearance integrity of the drug, or whether there is damage, cracks, stains, etc.

[0030] In order to accurately control the rotation speed of the rotating shaft 310, the medicine sorting device further includes a first driver, which is in transmission connection with the rotating shaft 310. If the rotating shaft 310 rotates only by the gravity of falling tablets, the falling speed of the tablets may be uneven or jammed. The first driver can be connected to control the rotation speed of the rotating shaft 310, that is, the falling speed of the medicines can be accurately controlled, and the speed at which the medicines fall one by one can be ensured.

[0031] To precisely control the deflector 510, the medicine dosing valve includes a second driver and a connecting shaft 500. The connecting shaft 500 is rotatably arranged at the connection of the first medicine outlet pipe 340 and the second medicine outlet pipe 350. A deflector 510 is arranged on the connecting shaft 500, and the second driver is in transmission connection with the connecting shaft 500. Among them, one end of the deflector 510 is connected to the connecting shaft 500, and the other end of the deflector 510 can make a reciprocating motion along the arc track of a circle with the connecting shaft 500 as the center. The deflector 510 is used to block the passage from the transparent medicine dosing pipe 300 to any one of the first medicine outlet pipe 340 or the second medicine outlet pipe 350. By using an electric signal to control the swing of the deflector 510, the speed is faster and more precise.

[0032] It should be noted that the medicine sorting device may further include a controller. The controller, the medicine identification component, and the second driver are in telecommunication connection. The controller controls the second driver to rotate clockwise or counterclockwise according to the identification result of the medicine identification component, driving the deflector 510 to open or close the passage from the transparent medicine dosing pipe 300 to any one of the first medicine outlet pipe 340 or the second medicine outlet pipe 350.

[0033] Furthermore, in order to better block the passage from the transparent medicine dosing pipe 300 to any one of the first medicine outlet pipe 340 or the second medicine outlet pipe 350 by the medicine dosing valve, the rotation angle of the connecting shaft 500 is 0 degrees to 120 degrees. Among them, the deflector 510 swings left and right with the connecting shaft 500 as the center through the connecting shaft 500 to block the passage of the first medicine outlet pipe 340 or the second medicine outlet pipe 350. In this application, the preferred swing angle is 0 degrees to 120 degrees. Too large or too small may cause the medicine to fall into the wrong channel, resulting in sorting failure.

[0034] To further isolate the medicine, the medicine retaining plate 320 includes a vertical portion 321 and a bent portion 322. One end of the vertical portion 321 is connected to the rotating shaft 310, and the other end is provided with the bent portion 322. The bent portion 322 extends in the rotating direction of the medicine retaining plate 320. Among them, if the medicine retaining plate 320 only has the vertical portion 321, the situation of medicine jamming may occur during the rotation process. By arranging the bent portion 322 at one end of the medicine retaining plate 320, the bent portion 322 can effectively isolate the medicine currently in the medicine retaining chamber 330, and it can also prevent the medicine that will enter the medicine retaining chamber 330 next from jamming on the medicine retaining plate 320, so that the medicine in the medicine retaining chamber 330 can be completely isolated from other medicines. The number of the medicine retaining plates 320 is 2 to 6. In this application, 4 is preferred. The number of the medicine retaining plates 320 is determined by the shape and size of the medicine.

[0035] To prevent the medicine from being damaged or squeezed during the falling process, the medicine retaining plate 320 is a flexible plate. Among them, when the medicine retaining plate 320 is a flexible plate and the medicine is falling, the medicine falling on the medicine retaining plate 320 can play a buffering role, and if the medicine gets stuck on the medicine retaining plate 320, it will not be squeezed.

[0036] To prevent the medicines from overlapping in the tube, the cross-sectional shape of the transparent medicine delivery tube 300 is any one of circular, square, and oval. Among them, the circular medicine delivery tube is mainly used for passing pill-shaped medicines, the square medicine delivery tube can pass cake-shaped medicines, and the oval medicine delivery tube can pass oval medicines. The specific shape can be changed according to different medicines. The medicines move in the medicine delivery tube, which can be through the action of gravity or the thrust from the medicine feeder 100.

[0037] To adapt to different medicine shapes, one end of the transparent medicine delivery tube 300 connected to the outlet slideway 200 is inclined. Among them, when the medicine is long strip-shaped, when the medicine falls into the medicine retaining chamber 330, the next medicine may also squeeze into the medicine retaining chamber 330. When the medicine enters the medicine retaining chamber 330 obliquely, the above situation can be avoided.

[0038] This application also discloses a medicine sorting system based on machine recognition, including the medicine sorting equipment based on machine recognition described in any one of the above, and further including a bracket 600. A conveyor belt 610 is installed at the lower part of the bracket 600. A number of positioning grooves 620 are provided on the conveyor belt 610, and medicine bottles 630 are arranged in the positioning grooves 620. A number of medicine sorting devices are installed at the upper part of the bracket 600. The medicine outlet of the first medicine outlet tube 340 is vertically corresponding to the moving track of the bottle mouth of the medicine bottle 630. Among them, after the medicine sorting is completed, the complete medicines can be introduced into the medicine bottle 630 through the first medicine outlet tube 340 to enter the next process section, while the incomplete and defective medicines enter the recycling box 640 through the second medicine outlet tube 350. In the specific work, the conveyor belt 610 sends the medicine bottle 630 below the medicine outlet of the first medicine outlet tube 340. After collecting a predetermined number of medicines, the conveyor belt sends the medicine bottle 630 filled with medicines into the next process section, and conveys a new empty medicine bottle 630 to below the medicine outlet of the first medicine outlet tube 340, and so on continuously, while the defective medicines all enter the recycling box 640 through the second medicine outlet tube 350.

[0039] It should be noted that the drug sorting system based on machine recognition further includes a drug recognition unit, a control unit, and a drug sorting unit: The drug recognition unit is used to recognize the integrity of the drug information obtained by the drug recognition component 400 and send the recognition signal to the control unit; among them, the drug information includes data such as the three-dimensional shape, contour data, or photo of the drug; The control unit is used to receive the recognition signal from the drug recognition unit and send an action signal to the drug sorting unit according to the recognition signal; among them, the control unit includes a single-chip microcomputer, a PLC controller, etc., which are responsible for receiving the recognition signal from the drug recognition unit and sending an action signal to the drug sorting unit to ensure accurate drug sorting; The drug sorting unit is used to receive the action signal and control the movement of the diversion plate 510. Among them, the drug sorting unit receives the action signal sent by the control unit, sends the action signal to the second driver, and the second driver rotates clockwise or counterclockwise to drive the diversion plate 510 to block the passage of the first medicine outlet pipe 340 or the second medicine outlet pipe 350.

[0040] In specific work, the drug enters the transparent medicine delivery pipe 300 through the inclined outlet chute 200 and enters the medicine retention chamber 330. When the drug continues to fall from the medicine retention chamber 330, the drug recognition component 400 obtains a photo of the drug, recognizes the integrity of the drug information obtained by the drug recognition component 400 and generates a recognition signal, and sends the recognition signal to the control unit. The control unit generates an action signal according to the recognition signal and sends the action signal to the second driver. If the first medicine outlet pipe 340 is the complete drug passage and the second medicine outlet pipe 350 is the recovered drug passage, then when the falling drug is a complete drug, the second driver drives the diversion plate 510 to rotate to block the second medicine outlet pipe 350, so that the drug flows out from the first medicine outlet pipe 340; when the falling drug is an incomplete drug, the second driver drives the diversion plate 510 to rotate to block the first medicine outlet pipe 340, so that the drug flows out from the second medicine outlet pipe 350.

[0041] The above embodiments only express the device layout mode of the present application, and its description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent application; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several adjustments and improvements can still be made, and these all belong to the protection scope of the present application; therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
