When the accommodating part drives the capsule to move, the capsule moves along the conveying channel. A weighing platform 24 for weighing and a first discharge port 231 and a second discharge port 232 are sequentially provided on the conveying channel along the conveying direction. , so that the capsule is first driven by the accommodating part to the weighing platform 24 for weighing during transportation, and then the capsule is taken out after weighing, and then the next accommodating part drives the capsule to move to the weighing platform 24 to weigh the next capsule, and the weighed capsule is driven to the subsequent discharge port for discharge. An openable and closable blocking member 22 is provided in the first discharge port 231, and the blocking member 22 can be closed when the capsule weight is qualified, and opened when the capsule weight is unqualified, or the blocking member 22 can be closed when the capsule weight is unqualified, and opened when the capsule weight is qualified, so as to realize the screening of qualified capsules and unqualified capsules.

[0026] In order to improve the stability of the containing part, in some embodiments, the conveying part of the conveying device 1 includes two groups of conveying structures, the two groups of conveying structures are arranged in parallel, and each of the containing parts is arranged between the two conveying structures and fixedly connected to the two conveying structures.

[0027] Specifically, each group of conveying structures includes a conveying member 11 and two connecting wheels 12, the two connecting wheels 12 are arranged in parallel, the conveying member 11 is sleeved between the two connecting wheels 12, so that the conveying members 11 of the two conveying structures are arranged in parallel, and each of the accommodating parts is sequentially arranged between the two conveying members 11 along the length direction of the conveying member 11. The conveying part of the conveying device 1 also includes a first driving member 13, which is connected to one of the connecting wheels 12 of the two groups of conveying structures and is used to drive the connecting wheels 12 to rotate. The several accommodating parts of the conveying device 1 include a fixed plate 14 and a limiting plate 15, the fixed plate 14 is horizontally arranged between the two conveying structures, and its two ends are respectively fixedly connected to the outer side surfaces of the two conveying members 11, the middle part of the fixed plate 14 is provided with a mounting groove 141, the limiting plate 15 is vertically arranged in the mounting groove 141, and the limiting plate 15 is provided with a limiting groove 151 for accommodating capsules. During implementation, the capsule is placed in the limiting groove 151 of the limiting plate 15, and the bottom of the capsule is placed on the conveying channel. The first driving member 13 drives one of the connecting wheels 12 of the two groups of the conveying structures to rotate, thereby driving the transmission of the two conveying members 11, driving the fixed plate 14 and the limiting plate 15 connected to the conveying member 11 to move along the conveying direction, and then driving the capsule to move along the conveying channel, passing through the weighing platform 24 and the discharge port in turn.

[0028] In some embodiments, the transmission member 11 is a chain or a belt, and the first driving member 13 is preferably a motor. When the transmission member 11 is a chain, the corresponding connecting wheel 12 is a gear, and the motor drives the gear to rotate, thereby driving the movement of the chain mounted on the two gears; when the transmission member 11 is a belt, the corresponding connecting wheel 12 is a pulley, and the motor drives the pulley to rotate, thereby driving the movement of the belt mounted on the two pulleys.

[0029] In order to ensure the accuracy of the inspection, in some embodiments, a controller can also be provided to control the motor to stop for a period of time after the motor-driven transmission member drives the capsule to move to the weighing platform 24, so that the capsule remains stationary for weighing, which is beneficial to improving the accuracy of the inspection; specifically, the stopping of the motor can be controlled by setting a sensor or by utilizing a delay device.

The guide device 2 includes a guide plate 21, and the guide plate 21 is horizontally arranged between the two conveying structures. Specifically, the mounting frame of the conveying structure is fixed on the workbench 3, and the guide plate 21 is fixedly connected to the mounting frame. Moreover, the guide plate 21 and the workbench 3 are located in the same horizontal plane, and the top of the guide plate 21 corresponds to the bottom of the limit plate 15 located above; the blocking member 22 includes a blocking plate 221 and a second driving member, and the blocking plate 221 is arranged in the first discharge port 231, and a rotating shaft is arranged at one end of the blocking plate 221, and the two ends of the rotating shaft are rotatably connected to the guide plate 21, and the cross-sectional area of ​​the first discharge port 231 gradually decreases from bottom to top. The second driving member is connected to the rotating shaft, and is used for driving the blocking plate 221 to swing around the rotating shaft through the rotating shaft, so that the swing stroke of the blocking plate 221 has a first position and a second position.

[0035] Preferably, the second driving member includes a swing motor, the driving angle of the swing motor is 0 to 90°, and the second driving member also includes a first gear 222 and a second gear 223. The first gear 222 is fixedly mounted on the rotating shaft at the end of the sealing plate 221, and the second gear 223 is meshed and rotatably connected with the first gear 222, and the second gear 223 is connected to the driving shaft of the swing motor. The driving force of the swing motor can be transmitted to the sealing plate 221 through the first gear 222 and the second gear 223. When the blocking plate 221 is located at the first station, the blocking plate 221 is horizontally fitted in the first discharge port 231, and the top surface of the blocking plate 221 and the top surface of the guide plate 21 are located on the same horizontal plane; when the blocking plate 221 is located at the second station, the blocking plate 221 is perpendicular to the guide plate 21; when the blocking plate 221 switches from the first station to the second station, the blocking plate 221 is driven by a swing motor to rotate downward 90°, and when the blocking plate 221 switches from the second station to the first station, the blocking plate 221 is driven by a swing motor to rotate upward 90°.

[0037] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0038] It is understandable that, in order to facilitate loading, a loading device such as a vibrating loading tray can also be set at the loading position to automatically place the capsule medicines in the accommodating portion in order, while preventing the staff from touching the medicines with their hands. In order to facilitate cleaning of the limit plate 15 and the guide plate 21, the limit plate 15 and the guide plate 21 are set to be detachable, and the limit plate 15 and the guide plate 21 can be fixed by bolt connection. In order to facilitate the separate storage of the inspected medicines, a material guide pipe can be installed below the first discharge port 231 and the second discharge port 232, and the material guide pipe can be tilted and led out to be placed in the qualified box and the unqualified box respectively, so that the inspected medicines can be stored separately.

[0039] Working principle: During implementation, according to the conveying direction, the capsule medicine is sequentially fed into the limiting groove 151 of the limiting plate 15, so that the capsule medicine is placed on the top surface of one end of the guide plate 21, and the first driving member 13 drives one of the connecting wheels 12 of the two groups of the conveying structures to rotate, thereby driving the transmission of the two conveying members 11, driving the fixed plate 14 and the limiting plate 15 connected to the conveying member 11 to move along the conveying direction, thereby driving the capsule to move along the length direction of the guide plate 21, passing through the weighing platform 24 and the discharge port in turn, and the capsule is firstly received by the receiving part during conveying. The capsule is driven to the weighing platform 24 for weighing, and then taken out after weighing. Then, the capsule is driven by the next accommodating part to move to the weighing platform 24 for weighing the next capsule, and the weighed capsule is driven to the subsequent discharge port for discharge. The weighing platform 24 sets a qualified range through the control system. When it is detected that the weight of the capsule medicine is not appropriate, the blocking member 22 is closed, and the capsule medicine is brought to the second discharge port 232 for discharge. When the weight of the capsule medicine is qualified, the blocking member 22 is opened, and the capsule medicine directly falls into the first discharge port 231 for discharge.
