Description

Technical Field

[0001] This utility model relates to the technical field of drug sorting devices, specifically a drug verification and sorting device for pharmacies. Background Technology

[0002] Most existing hospital pharmacies are equipped with drug sorting devices that can automatically dispense medications based on prescription information. These devices typically read prescription information, retrieve the corresponding medication from the shelf, and transport it to a medicine basket, achieving a degree of automation. However, existing drug sorting devices have some shortcomings in the medication transfer process. For example, most devices lack effective limits on the amount of medication dispensed at the discharge end, resulting in medications being piled up haphazardly in the medicine basket. Pharmacists still need to perform further manual sorting and verification upon receiving the medications, which not only increases their workload but also prolongs patients' waiting time for their prescriptions.

[0003] Patent CN218950205U discloses a drug sorting device, including a bracket, a motor fixedly mounted on the bracket, a first rotating shaft fixedly connected to the output end of the motor, a second rotating shaft rotatably mounted on the bracket, a synchronous belt connecting the first and second rotating shafts, a drive gear fixedly mounted on the second rotating shaft, and a conveyor belt for transporting drugs meshing with the drive gear. A drug storage box is placed on the bracket. The motor drives the first rotating shaft to rotate, the first rotating shaft drives the second rotating shaft to rotate via the synchronous belt, the second rotating shaft drives the drive gear to rotate, and the drive gear drives the conveyor belt to move, thereby transporting drugs. By moving the position of the second connecting rod, the position of the second roller is adjusted. Through the cooperation of the first and second rollers, the discharge amount at the discharge end of the conveyor belt can only be the corresponding amount of material discharged at one time according to the position of the second roller.

[0004] Although the existing technology described above limits the amount of material discharged at the conveyor belt outlet by the cooperation of the first and second rollers, allowing the discharge amount to be adjusted according to the position of the second roller, it still has the following drawbacks: On the one hand, due to the gap between the two adjacent first rollers and the fact that the first rollers cannot rotate independently, the corners of the boxed medicines are easily stuck between the adjacent rollers, affecting the smooth transport of the medicines; on the other hand, the existing sorting device lacks a medicine verification function. When medicines for multiple patients are transported in sequence, there is no effective verification mechanism, and the medicine baskets are fixed and cannot be automatically replaced, which can easily lead to the medicines being missorted or mixed into the medicine baskets of other patients, affecting medication safety. In view of this, we propose a pharmacy medicine verification and sorting device. Utility Model Content

[0005] The purpose of this invention is to provide a pharmacy drug verification and sorting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pharmacy drug verification and sorting device includes a first U-shaped plate, inside which is a first conveyor belt for transporting drugs. A first motor, which is a stepper motor, is located on the front side of the first U-shaped plate near the left end to drive the first conveyor belt. The first motor is powered by an external power source and drives one of the rotating shafts of the first conveyor belt to rotate, thereby causing the first conveyor belt to transport drugs to the right. Guide components are provided on both the front and rear sides of the inner wall of the first U-shaped plate. The bottom of the guide components is close to the upper surface of the first conveyor belt. The right ends of the two guide components arranged in opposite directions can be adjusted forward and backward, thereby adjusting the distance between the right ends of the two guide components, and thus ensuring that the drugs are transported in an orderly manner with the center in place.

[0008] The first U-shaped plate is equipped with a verification component, which is located to the right of the guide component. The verification component has six barcode scanners in the front, back, left, right, top, and bottom positions, which can scan the barcodes on the medicine boxes to achieve the verification function. An infrared counter is provided on the first U-shaped plate near the output end of the first conveyor belt to count the number of medicines after verification, that is, the number of medicines required for a single patient. When the medicines are verified and the infrared counter detects the output of the last box of medicines, the first motor stops working and the third motor starts working to transport the medicine basket containing the medicines backward, so that the new medicine basket moves directly under the guide plate. Then the first motor starts working and the third motor stops working to avoid the mixing of medicines.

[0009] A second U-shaped plate is provided at the bottom right side of the first U-shaped plate. A second conveyor belt is provided inside the second U-shaped plate. A third motor for driving the second conveyor belt is provided on the right side of the second U-shaped plate near the front end. The third motor is powered by an external power source. The second motor, the third motor, the first motor, and the infrared counter are coordinated by the same controller. Medicine baskets are placed at equal intervals on the top of the second conveyor belt. The third motor drives one of the rotating shafts of the second conveyor belt to rotate, thereby causing the second conveyor belt to transport the medicine baskets backward.

[0010] Preferably, the guiding component includes a first U-shaped fixing seat and a second U-shaped fixing seat fixedly connected to the inner wall side of the first U-shaped plate.

A second motor for driving the guide belt is provided at the top of the U-shaped movable plate and near the left end. The second motor is powered by an external power source and starts and stops synchronously with the first motor. The second motor drives the guide belt to work, and the guide belt can actively move the medicine to the right. In conjunction with the first conveyor belt, it can ensure that the medicine moves smoothly to the right and avoid the medicine getting stuck.

[0012] Preferably, an internally threaded fixing tube is provided in the middle of the front side of the second rotating block, and a threaded rod is internally threaded to the internally threaded fixing tube. A third U-shaped fixing seat is provided on the right side of the back of the U-shaped movable plate. A third rotating block is rotatably connected between the upper and lower sides of the inner wall of the third U-shaped fixing seat. The front end of the threaded rod is rotatably connected to the middle of the rear side of the third rotating block. By rotating the threaded rod, the position of the right end of the U-shaped movable plate can be adjusted, thereby adjusting the distance between the right ends of the two guide components, so that the medicine moves closer to the middle of the first conveyor belt, which is beneficial for the verification component to scan the barcode on the medicine box.

[0013] Preferably, a rotating wheel is provided on the outer wall of the threaded rod near the rear side of the third rotating block, so as to facilitate the operator to rotate the threaded rod.

[0014] Preferably, the verification component includes a fixed base plate, the front and rear ends of which are fixedly connected to the front and rear sides of the inner wall of the first U-shaped plate, respectively.

A connecting horizontal plate is provided in the middle of the left and right sides of the U-shaped frame. An mounting inclined plate is provided on the opposite sides of the two connecting horizontal plates. A barcode scanner is provided at the bottom of the two mounting inclined plates, respectively, for scanning the barcodes located on the left and right sides of the medicine box. This ensures that the barcode on the medicine box is effectively identified without requiring the barcode on the medicine box to always face the same position.

[0016] Preferably, a guide plate is provided between the front and rear sides of the inner wall of the first U-shaped plate and near the right end. The left side of the guide plate is in contact with the outer surface of the first conveyor belt, and the right side of the guide plate is located directly above the medicine basket, guiding the checked medicine to the medicine basket.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This pharmacy's drug verification and sorting device, by setting up verification components, uses six barcode scanners to scan the barcodes on the medicine boxes from all angles during the drug transfer process, ensuring the accuracy of drug verification.
