If the set weight is met, the drive unit is activated to drive the two push plates to move toward the quantitative discharge port, and the drugs are discharged through the quantitative discharge port. If the drug weight is greater than the set weight, the push plate movement speed is controlled and the weight change of the weighing trough is monitored in real time. When the output drug dosage reaches the set value, the push plate is driven to move in the opposite direction to push back the excess drug. If the drug weight is less than the set weight, the drug is further added to the weighing trough and the weight change of the weighing trough is monitored in real time until the set value is reached. This achieves accurate weighing and quantitative discharge of drugs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A specific embodiment of the present invention is described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0031] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] To facilitate patient dosage, medications are typically packaged in individual, pre-packaged quantities. Therefore, on the pharmaceutical production line, medications are first weighed and packaged. Common medications include solids, liquids, and semi-solids, and different medication forms require different weighing methods on the production line.

[0033] Currently, weighing systems on production lines are often used in conjunction with drug delivery systems. For example, dynamic weighing is used for solid and semi-solid drugs, with a belt scale installed along the drug delivery path. This controls the material flow rate and coordinates with the belt scale to achieve drug weighing. For liquid drugs, flow control is used, with a weighing filler ensuring precise delivery of the liquid dosage.

[0034] However, existing weighing methods for pharmaceutical production lines rely primarily on flow rate control and rough adjustments to dosage input, often only providing a rough dosage range and making it difficult to accurately weigh the dosage. While methods like balance weighing are suitable for accurately weighing small batches of drugs, they are not suitable for large-scale pharmaceutical production lines.

[0035] To this end, an embodiment of the present invention provides a weighing device for a pharmaceutical production line, which can be set on the pharmaceutical production line to weigh and quantitatively output the pharmaceuticals on the conveying path, and ensure that the output pharmaceutical dosage can reach the set value, thereby achieving accurate weighing of the pharmaceutical dosage.

[0036] At least one embodiment of the present invention provides a weighing device for a pharmaceutical production line, comprising a mounting seat, a pharmaceutical input port, a weighing assembly, and a discharging assembly. The pharmaceutical input port is provided on the mounting seat, and a quantitative discharging assembly is provided in the pharmaceutical input port for discharging the pharmaceuticals in intervals and in a quantitative manner; the weighing assembly comprises a weighing trough and a weight detection system, the pharmaceutical input end is connected to the weighing trough, the weight detection system is mounted on the mounting seat, and the weighing trough is movably provided on the weight detection system, and the weight detection system is used to detect the weight change of the weighing trough in real time; the discharging assembly comprises at least two push plates and a driving unit, the two push plates are slidably provided in the weighing trough, and the lower edge of the push plates is in contact with the bottom of the weighing trough, and the driving unit is used to drive the two push plates to slide back and forth in the weighing trough; wherein, a quantitative discharging port is provided on the bottom of the weighing trough, and the quantitative discharging port is located on one side of the two push plates.

[0037] In the weighing device for a pharmaceutical production line provided by the above-mentioned embodiment of the present invention, the drugs on the production line enter the weighing trough in a quantitative manner through the drug input port, and the weight detection system obtains the weight value of the drugs in the weighing trough by detecting the weight change of the weighing trough. If the weight value of the drugs reaches the set value, the driving part pushes the two push plates to move so that the drugs are discharged from the discharge port; if the weight value of the drugs does not reach the set value, the discharge amount of the drugs can be controlled by controlling the moving speed of the push plates, or drugs can be gradually added to the weighing trough, and the weight changes of the weighing trough can be monitored in real time, so as to accurately control the dosage of the drugs output from the discharge port.

[0038] The present invention is described below by means of several specific embodiments. To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the present invention appears in more than one drawing, the component may be represented by the same reference numeral in each drawing.

[0039] Reference Figure 1 、 Figure 2 and Figure 3As shown, an embodiment of the present invention provides a weighing device for a drug production line, comprising a mounting base 1 , a drug input port 2 , a weighing component 3 and a discharging component 4 . The medicine input port 2 is arranged on the mounting base 1, and a quantitative discharge component 21 is provided in the medicine input port 2, which is used to discharge the medicines at intervals and in a quantitative manner; the weighing component 3 includes a weighing trough 31 and a weight detection system 32, the medicine input end is connected to the weighing trough 31, the weight detection system 32 is installed on the mounting base 1, and the weighing trough 31 is movably arranged on the weight detection system 32, and the weight detection system 32 is used to detect the weight changes of the weighing trough 31 in real time; the discharge component 4 includes at least two push plates 41 and a driving part 42, the two push plates 41 are slidably arranged in the weighing trough 31, and the lower side of the push plates 41 is in contact with the bottom of the weighing trough 31, and the driving part 42 is used to drive the two push plates 41 to slide back and forth in the weighing trough 31; wherein, a quantitative discharge port 43 is opened on the bottom of the weighing trough 31, and the quantitative discharge port 43 is located on one side of the two push plates 41.

[0040] Specifically, the mounting base 1 is used to mount and fix the drug input port 2, the weighing assembly 3, etc. The mounting base 1 can be used to install a weighing device on the drug production line, thereby achieving the goal of weighing the drugs on the production line and then outputting them in a quantitative manner. For example, the mounting base 1 is a frame structure, and the drugs on the drug production line are transported to the packaging system via a conveyor belt. The mounting base 1 can be located at the end of the conveyor belt. The drugs on the conveyor belt are first weighed and then transported to the packaging system for packaging, thereby accurately controlling the dosage of the drugs. Therefore, the specific structure of the mounting base 1 is not particularly limited in the present invention, and in actual application, it can be specifically selected according to the method of transporting the drugs on the production line.

[0041] A drug inlet 2 is provided on the mounting base 1, through which drugs on the production line can enter the weighing trough 31. For example, the drug inlet 2 is an inclined trough-shaped structure. Drugs on the drug production line are transported via a conveyor belt, and a weighing device is provided at the end of the conveyor belt. Drugs on the conveyor belt can be directly transported into the drug inlet 2, thereby transporting the drugs to the weighing trough 31. Furthermore, a quantitative discharge assembly 21 is provided in the drug inlet 2. The quantitative discharge assembly 21 can achieve the stepwise input of a certain dosage range of drugs into the weighing trough 31 by controlling the flow rate of drug input or discharging the drugs at intervals, facilitating subsequent weighing and quantitative discharge.

[0042] The weighing assembly 3 includes a weighing trough 31 and a weight detection system 32. The weighing trough 31 can be a trough-shaped structure with a horizontal or curved bottom. The weight detection system 32 can be a pressure weighing device. The weight detection system 32 is mounted on the mounting base 1, and the weighing trough 31 is mounted on the weight detection system 32. The weight detection system 32 can monitor the weight changes of the weighing trough 31 in real time. For example, after the medicine is delivered to the weighing trough 31, the overall weight of the weighing trough 31 changes. The weight change value of the weighing trough 31 is the weight of the input medicine.

[0043] The discharging assembly 4 includes two push plates 41 and a driving part 42. The push plates 41 are slidably arranged in the weighing trough 31, and the lower side of the push plates 41 is in contact with the bottom of the weighing trough 31. A quantitative discharging port 43 is provided on the bottom of the weighing trough 31 for discharging the weighed medicines.

[0044] During the drug production process, the drugs on the production line enter the weighing trough 31 through the drug input port 2. The weight detection system 32 detects the weight of the input drugs and compares the drug weight value with the set drug dosage standard value to determine the weight of the drugs in the weighing trough 31. If it meets the set weight, the drive unit 42 is started to drive the two push plates 41 to move to one side of the quantitative discharge port 43 to output the drugs through the quantitative discharge port 43; if the drug weight is greater than the set weight, the moving speed of the push plate 41 can be controlled and the weight change of the weighing trough 31 can be monitored in real time. When the output drug dosage reaches the set value, the push plate 41 is driven to move in the opposite direction; if the drug weight is less than the set weight, the drug continues to be input until the set value is reached, thereby achieving accurate weighing and quantitative discharge of the drugs.

[0045] In the above embodiment, when the weight of the medicine in the weighing trough 31 is greater than the set value, the remaining medicine will be pushed back by the push plate 41. If it continues to be stored in the weighing trough 31 and mixed with the newly input medicine, multiple weighings will cause too much medicine to be deposited in the weighing trough 31, which is not conducive to the efficiency and accuracy of weighing.

[0046] To this end, an embodiment of the present invention provides an improved approach.

[0047] Reference Figure 1 、 Figure 2As shown, the bottom of the weighing trough 31 is also provided with a residual discharge port 44, and the residual discharge port 44 and the quantitative discharge port 43 are symmetrically arranged on both sides of the two push plates 41. During weighing, if the weight of the medicine in the weighing trough 31 is greater than the set value, the two push plates 41 can be driven by the driving unit 42 to move toward the residual discharge port 44, thereby discharging the excess medicine from the residual discharge port 44. Alternatively, when the weight detection system 32 detects that the weight of the medicine is greater than the set value, the medicine that does not meet the dosage standard can be directly pushed into the residual discharge port 44. However, since the dosage of the medicine input into the weighing trough 31 by the quantitative discharge component 21 is kept within a certain dosage range, it is difficult to accurately reach the set value. Therefore, it is still necessary to accurately control the dosage of the output medicine by controlling the moving speed of the push plate 41.

[0048] Furthermore, a conveying portion 5 is provided below the quantitative discharge port 43, and a circulating feeding portion 6 is provided below the residual discharge port 44. The discharge end of the circulating feeding portion 6 is connected to the weighing trough 31. After being accurately weighed in the weighing trough 31, the medicine is discharged from the quantitative discharge port 43. The quantitative medicine falls onto the conveying portion 5 and can be transported to the packaging system in the production line for packaging through the conveying portion 5. After the excess medicine is discharged through the residual discharge port 44, it is collected and can be transported to the weighing trough 31 again through the circulating feeding portion 6. When the weight of the medicine in the weighing trough 31 is less than the set value, the circulating feeding portion 6 can be used to input the medicine into the weighing trough 31 without the need to input it from the medicine input port 2. This can effectively avoid interfering with the frequency of the medicine input port 2 inputting the medicine into the weighing trough 31 at intervals.

[0049] In the above embodiment, when the weight of the medicine in the weighing trough 31 is greater than the set weight, the medicine cannot be completely pushed into the quantitative discharge port 43 by the pushing plate 41. It is necessary to control the moving speed of the pushing plate 41 to control the dosage of the medicine dropped, which is not convenient for accurately controlling the dosage of the medicine.

[0050] To this end, an embodiment of the present invention provides an improved approach.

[0051] Reference Figure 3 As shown, a baffle plate 45 is provided at the edge of the quantitative discharge port 43 close to the push plate 41, and a plurality of leakage ports are spaced apart on the baffle plate 45. When the push plate 41 moves, the push plate 41 away from the quantitative discharge port 43 can be aligned with the edge of the discharge port on the side where the leakage port is provided.

[0052] Specifically, when the two push plates 41 move toward the side close to the quantitative discharge port 43, they push the medicines from the leakage port to the quantitative discharge port 43. A portion of the medicines will temporarily stay between the two adjacent leakage ports. As the push plate 41 away from the quantitative discharge port 43 gradually moves toward the edge of the baffle plate 45, it will gradually push the medicines on the baffle plate 45 down. When the dosage of the medicines is equal to the set value, the push plate 41 moves to a position aligned with the end of the baffle plate 45, and the push plate 41 can push all the medicines down. When the dosage of the medicines is greater than the set value, the medicines can be gradually pushed down by controlling the movement speed of the push plate 41 and monitoring the weight change of the weighing trough 31 in real time. When the output medicine dosage reaches the set value, the push plate 41 moves in the opposite direction and pushes the excess medicines into the residual discharge port 44.

[0053] Furthermore, the opening of the leakage port gradually expands as it moves away from the push plate 41. For example, the opening of the leakage port may be trapezoidal, with the opening on the side of the leakage port away from the blocking plate 45 being larger than the opening on the other side. As a result, the distance between two adjacent leakage ports gradually increases as it moves closer to the push plate 41. Therefore, when the push plate 41 pushes the medicine that is stuck between the two adjacent leakage ports, the medicine can be effectively prevented from falling out of the leakage ports.

[0054] In one embodiment of the present invention, referring to Figure 2 As shown, the movable end of the driving part 42 is movably connected to the two pushing plates 41. The two pushing plates 41 and the weighing trough 31 will not have relative displacement in the vertical direction, and the two pushing plates 41 and the driving part 42 can have any relative displacement in the vertical direction.

[0055] For example, a chute is provided on the weighing trough 31, and a slider is provided on the push plate 41, which slides in the chute. Utilizing the slider and chute, the push plate 41 can be restricted to sliding only along the length of the weighing trough 31. Therefore, when the weighing trough 31 undergoes vertical displacement due to weight changes, the push plate 41 is moved along with it, thereby ensuring that the bottom edge of the push plate 41 always fits in contact with the bottom of the weighing trough 31. This allows the push plate 41 to push all the medicines when it moves, avoiding any residue and improving weighing accuracy.

[0056] In an exemplary embodiment of the present invention, the driving portion 42 includes two electric push rods respectively connected to the two push plates 41 , and the electric push rods are fixedly connected to the mounting base 1 .

[0057] Specifically, one end of the electric push rod is fixedly connected to the mounting base 1, and the telescopic end of the electric push rod is connected to the push plate 41. A strip hole is vertically opened on the push plate 41, and the telescopic end of the electric push rod passes through the strip hole. Limit sleeves fixedly mounted on the electric push rod are provided on both sides of the push plate 41. This allows the electric push rod to drive the push plate 41 to move back and forth, and when the push plate 41 undergoes vertical displacement, it will not be restricted by the electric push rod.

[0058] In another exemplary embodiment of the present invention, a sealing sleeve is provided on the edge where the pusher plate 41 is in contact with the weighing trough 31. The provision of the sealing sleeve facilitates the pusher plate 41 to push the medicine more thoroughly and avoid omission.

[0059] In one embodiment of the present invention, the weighing device for a pharmaceutical production line further includes a touch screen 7 and a control component 8. The touch screen 7 is used to display the weight data of the weighing trough 31 in real time and set the dosage standard value. The control component 8 is electrically connected to the drive unit 42 and the detection system, and is used to control the operation of the drive unit 42 based on the detection data of the detection system.

[0060] Specifically, the dosage standard value of the weighed medicine is set through the touch screen 7, and the data information is transmitted to the control component 8, and the weight data information detected by the weight detection system 32 is also transmitted to the control component 8, so that the control component 8 controls the driving direction, driving speed, etc. of the driving part 42 according to the received data information.

[0061] The above inventions are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
