The weighing sensor 7 corresponds to the discharge end of the conveying tube 15. The medicine falls on the weighing sensor 7 from the discharge end of the conveying tube 15. The weight of the medicine is weighed by the weighing sensor 7, and the obtained weight data is transmitted to the controller. After receiving the weight signal of the medicine transmitted by the weighing sensor 7, the controller can determine whether the weight of the medicine is correct. Indeed, when the medicine is damaged, the weight of the medicine will be reduced, so the controller will control the output shaft of the motor of the driving component in this embodiment to rotate, so that the sorting platform 6 is tilted, so that the damaged medicine on the weighing sensor 7 rolls into the collection frame 4. When the weight of the medicine is correct, the controller will control the output shaft of the motor to rotate in the opposite direction, so that the sorting platform 6 is tilted to the other side, so that the medicine falls on the transmission conveyor belt 2, and the medicine is transported to the sorting frame 13 through the transmission of the conveyor belt 2, so that the complete and damaged medicines are sorted, and the sorting efficiency of the medicines is improved. The use of the weighing sensor 7 and the controller used in this embodiment is the existing technology, and no new program or algorithm is involved;
[0022] like Figure 1As shown, a third slide groove is provided on the top of the mounting frame 3, and a second slider which is slidably matched with the second slide groove and fixed to the bottom of the collecting frame 4 is provided in the third slide groove. The third slider is welded or glued to the bottom of the collecting frame 4, and the collecting frame 4 is fixed to the top of the mounting frame 3 by sliding the third slider into the third slide groove, so as to facilitate the installation and disassembly of the collecting frame 4. When there are too many damaged drugs in the collecting frame 4, the collecting frame 4 can be removed from the mounting frame 3 to empty the drugs in the collecting frame 4; and magnets are fixed to the side walls of the sorting frame 13, and metal blocks which are attracted to each other by magnets are fixed on the supporting columns of the drug conveying frame 1 at the discharging end of the conveyor belt 2, so as to facilitate the fixing of the sorting frame 13 at the discharging end of the conveyor belt 2. When there are too many drugs in the sorting frame 13, the sorting frame 13 can be removed from the drug conveying frame 1 to empty the drugs in the sorting frame 13 for subsequent drug sorting;
[0023] like Figure 1 As shown, a guide plate 14 is obliquely arranged in the sorting frame 13, and the inner wall of the sorting frame 13 is welded or welded with an inclined guide plate 14. When the medicine falls from the conveyor belt 2 onto the guide plate 14, and then rolls along the guide plate 14 into the sorting frame 13, the guide plate 14 reduces the height of the medicine to avoid damage to the medicine;
[0024] like Figure 1 and Figure 2 As shown, the top of the weighing sensor 7 and the top of the sorting platform 6 are located on the same horizontal plane. When the sorting platform 6 is tilted, the medicine can roll from the weighing sensor 7 to the sorting platform 6 and then fall from the edge of the sorting platform 6, so that the medicine can roll more smoothly on the sorting platform 6.
[0025] During actual use, the medicine is put into the feed hopper 9, and the blocking component blocks the conveying pipe 15. When the medicine needs to be sorted, the conveying pipe 15 is unblocked by the blocking component, so that the medicine passes through the conveying pipe 15 and falls onto the weighing sensor 7 on the top of the sorting platform 6, and is weighed by the weighing sensor 7. When the weight of the medicine meets the standard, the driving component drives the sorting platform 6 to tilt, so that the medicine falls from the sorting platform 6 to the transmission conveyor belt 2, and then the medicine is transported to the sorting frame 13 through the conveyor belt 2 to collect the medicine. If the weight of the medicine does not meet the standard, the driving component causes the sorting platform 6 to tilt to the other side, so that the medicine falls from the sorting platform 6 to the collection frame 4, thereby distinguishing and sorting the complete or damaged medicine, thereby improving the sorting efficiency.
[0026] Example 2
[0027] This embodiment further illustrates the technology. Figure 1 and Figure 3As shown, the blocking component includes a mounting groove provided on the delivery pipe 15, and two symmetrically distributed first slide grooves are provided on the inner wall of the delivery pipe 15 corresponding to the mounting groove, and a blocking plate 19 sliding in the slide groove is provided between the two first slide grooves, one side of the blocking plate 19 is located outside the mounting groove and fixed with a limiting plate 17, an insertion hole is provided on the outer wall of the delivery pipe 15, and a plug rod 18 plugged with the insertion hole is fixed on the limiting plate 17, the diameter of the delivery pipe 15 is smaller than the length of the blocking plate 19, the blocking plate 19 moves in the two first slide grooves between the inner walls of the delivery pipe 15, one side of the blocking plate 19 is located in the delivery pipe 15, and the other side thereof is located outside the delivery pipe 15, the blocking plate 19 located outside the delivery pipe 15 is connected to the limiting plate 17, a plug rod 18 is welded or glued on the inner wall of the limiting plate 17, and the plug rod 18 is plugged with the insertion hole provided on the outer wall of the delivery pipe 15. When in use, The limiting plate 17 is moved to drive the blocking plate 19 to move in the first slide groove in the conveying pipe 15. When the side wall of the blocking plate 19 contacts the inner wall of the conveying pipe 15, the insertion rod 18 on the limiting plate 17 is inserted into the insertion hole of the outer wall of the conveying pipe 15, so that the conveying pipe 15 is blocked by the blocking plate 19 to prevent the medicine from falling onto the sorting platform 6 through the conveying pipe 15. The diameter of the gap between the blocking plate 19 and the inner wall of the conveying pipe 15 can also be adjusted according to the diameter of different medicines, so that the diameter of the medicine is adapted to the gap, so that the amount of medicine falling on the sorting platform 6 is fixed, and the medicine can be better sorted. The discharging end of the conveying pipe 15 extends out of the through slot and approaches the sorting platform 6. Without affecting the inclination of the sorting platform 6, the discharging end of the conveying pipe 15 approaches the sorting platform 6, so that the distance the medicine falls is reduced, and it is prevented that the medicine is damaged when it falls too far and contacts the weighing sensor 7 of the sorting platform 6.
