Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical granule packaging technology, and in particular to a device for precise quantitative feeding of pharmaceutical granules. Background Technology

[0002] Health supplements are a type of food, sharing the common characteristics of general food, and can regulate the body's functions. Modern health supplements are generally processed in factories using fully automated processes, which are more hygienic and efficient.

[0003] However, in the packaging process of health supplements, quantitative sorting and packaging are generally carried out by machinery and equipment. By controlling the machine, bagged health supplements are quantitatively dispensed into boxes according to multiple varieties and fixed dosage ratios, making them convenient to carry after sealing. Since the accuracy of the quantity of each granule in health supplements is crucial, the need for feeding equipment with high accuracy and high reliability is urgent. Therefore, this application proposes a precise quantitative feeding device for pharmaceutical granules to ensure the accurate quantity of granules dispensed. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a precise quantitative feeding device for pharmaceutical granules with accurate output quantity.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a precise quantitative feeding device for pharmaceutical granules, including a sorting ring body. The inner circumference of the sorting ring body is distributed with multiple vertically arranged sorting and feeding channels. Each sorting and feeding channel is provided with a movable pusher plate below it and a discharge execution mechanism that drives each movable pusher plate to extend and retract radially along the sorting ring body. Each movable pusher plate is provided with a pharmaceutical granule discharge port corresponding to each sorting and feeding channel.

[0006] As a preferred technical solution, when the movable pusher plate is retracted, the granule outlet is located below the sorting and feeding channel; when the movable pusher plate is extended, the granule outlet is located outside the sorting ring.

[0007] As a preferred technical solution, the circumference of the sorting ring is provided with multiple radial guide grooves, and each of the movable pusher plates slides along the corresponding radial guide groove.

[0008] As a preferred technical solution, there is a reserved gap between the top of the movable pusher plate and the bottom of the sorting and unloading channel.

[0009] As a preferred technical solution, the discharge actuator is a push-pull electromagnet, and the telescopic rod of the push-pull electromagnet is fixedly connected to one end of the movable push plate.

[0010] As a preferred technical solution, a receiving tank is provided outside the plurality of movable pusher plates.

[0011] As a preferred technical solution, the receiving tank is a conical tank with a narrowed bottom, and the top opening of the receiving tank is located outside the plurality of movable push plates.

[0012] As a preferred technical solution, a pill counter is provided at the bottom outlet of the receiving tank.

[0013] As a preferred technical solution, it also includes a controller, which controls the number of discharge executions of the discharge actuator. The number of discharge particles detected by the particle counter is transmitted to the controller, and the controller compares and judges the detected number of discharge particles with the number of discharge executions.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: This application utilizes movable pusher plates to achieve single-particle feeding of medicine granules. By arranging multiple movable pusher plates and combining them with independently controlled multiple discharge actuators, the movable pusher plates can move according to the required number of medicine granules. This method of one-to-one correspondence between movable pusher plates, discharge actuators, and medicine granules can achieve the purpose of accurate feeding of medicine granules. In addition, combined with the reserved gap of medicine granules, it can be ensured that medicine granules of various postures can be successfully discharged in one go without the occurrence of medicine jamming. Furthermore, the medicine granule counter at the lower discharge port detects the number of medicine granules and feeds it back to the controller. The controller compares the number of medicine granules received with the number of actuated discharge actuators to detect whether the equipment is faulty and whether the discharge is accurate. This feedback method achieves closed-loop control. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0018] like Figure 1 and Figure 2 As shown, a pharmaceutical granule sorting and feeding mechanism includes a mounting frame on which a storage tank 100, a sorting and feeding device 200, and a receiving tank 300 are mounted. The storage tank 100 is positioned above the sorting and feeding device 200 and fixed to the mounting frame, while the receiving tank 300 is positioned below the sorting and feeding device 200 and fixed to the mounting frame. The sorting and feeding device 200 is rotatably mounted on the mounting frame and includes a slow-release sorting device and a quantitative feeding device. The slow-release sorting device is used to sort and temporarily store the pharmaceutical granules. The quantitative feeding device is used to discharge the temporarily stored pharmaceutical granules in the slow-release sorting device according to a specified quantity, and finally collects them into a medicine box through the receiving tank 300, thus completing the precise quantitative feeding of pharmaceutical granules. The quantitative feeding device is the precise quantitative feeding device for pharmaceutical granules of this application.

[0019] like Figure 2 and Figure 3As shown, the precise quantitative feeding device for pharmaceutical granules includes a rotating sorting ring 201. The inner wall of the sorting ring 201 is provided with a storage ring platform 202. Multiple vertically arranged sorting and feeding channels 203 are distributed on the storage ring platform 202. The sorting ring 201 also has a guide cone 204 that slopes downwards from the center to the storage ring platform 202. Above the sorting ring 201 is a storage tank 100 that continuously supplies pharmaceutical granules. Pharmaceutical granules continuously enter the sorting ring 201 from the storage tank 100. Within the sorting ring 201, the material enters the sorting and feeding channel 203 along the guide cone 204. Within the sorting and feeding channel 203, the medicine granules are sorted, arranged, and temporarily stored. Below each sorting and feeding channel 203 is a corresponding movable pusher plate 205 and a discharge actuator that drives each movable pusher plate 205 to extend and retract radially along the sorting ring 201. Each movable pusher plate 205 has a medicine granule discharge port 206 corresponding to each sorting and feeding channel 203. The size of each medicine granule discharge port 206 is only sufficient to hold one medicine granule, ensuring that only one medicine granule is discharged during each extension and retraction of the movable pusher plate 205.

[0020] The number of movable pusher plates 205 corresponds one-to-one with the number of sorting and feeding channels 203. A movable pusher plate 205 is located below each sorting and feeding channel 203, and each movable pusher plate 205 is equipped with a discharge actuator. The discharge actuator drives the corresponding movable pusher plate 205 to extend and retract along the sorting ring 201. When the movable pusher plate 205 is retracted, the granule outlet 206 is located below the sorting and feeding channel 203. (See attached image for retracted state). Figure 6 When the movable pusher plate 205 is extended, the granule outlet 206 is located outside the sorting ring 201. (See attached image for extended state.) Figure 7 Each of the aforementioned dispensing actuators is independently controlled, and can operate simultaneously or separately under the control of the controller. This means that each of the movable pusher plates 205 is independently extended and retracted. The number and frequency of the dispensing actuator's actions are related to the number of pills to be dispensed. In this embodiment, there are 12 movable pusher plates 205. When 5 pills need to be dispensed, 5 of the dispensing actuators are controlled to operate simultaneously; when 10 pills need to be dispensed, 10 of the dispensing actuators are controlled to operate simultaneously; when 24 pills need to be dispensed, all 12 dispensing actuators can be controlled to operate simultaneously once, and then controlled to operate simultaneously again. Of course, the number of movable pusher plates 205 is not limited to 12; it can be 24, 30, or more.

[0021] See Figure 4The sorting ring 201 has multiple radial guide grooves 207 around its periphery, and each movable pusher plate 205 slides and extends along the corresponding radial guide groove 207. In this embodiment, the sorting ring 201 is composed of two parts, an upper body and a lower body. The radial guide grooves 207 are located at the bottom end of the upper body. The lower body is used to install the discharge actuator and cooperates with the upper body to limit the movable pusher plate 205. The left and right widths of the radial guide grooves 207 correspond to the left and right widths of the movable pusher plate 205, and also limit the movable pusher plate 205.

[0022] In this embodiment, the discharge actuator is a push-pull electromagnet 208, and the telescopic rod of the push-pull electromagnet 208 is fixedly connected to one end of the movable pusher plate 205. The push-pull electromagnet 208 is a miniature type, which has two advantages: firstly, its small structural size and small space occupation; secondly, its electromagnetically controlled telescopic action is fast, which can improve the discharge speed and increase the efficiency of high-frequency operation. Of course, the discharge actuator is not limited to a push-pull electromagnet; it can also be other telescopic mechanisms, such as a telescopic rod.

[0023] Because the pills are roughly elliptical in shape, their posture within the sorting and feeding channel 203 and the pill outlet 206 is random; they may be upright, flat, or tilted. To ensure that pills of various postures can be successfully pushed out by the movable pusher plate 205 one pill at a time, a pre-reserved gap 209 is provided between the top of the movable pusher plate 205 and the bottom of the sorting and feeding channel 203. The height of the pill outlet 206 of the movable pusher plate 205 is equal to the height of a flattened pill. See [link to relevant documentation]. Figure 8 At this time, the reserved gap 209 can accommodate 1 / 2 of a pill. When the movable pusher plate 205 extends, the pill located in the reserved gap 209 will not be pushed out or stuck. The height of the pill outlet 206 of the movable pusher plate 205 plus the height of the reserved gap 209 is equal to the height of the upright pill. See [reference needed]. Figure 9 .

[0024] Because the movable pusher plate 205 extends and retracts very quickly, its combination with the loose feeding of the granules and the setting of the reserved gap 209 can ensure that granules of various postures are pushed out by the movable pusher plate 205 one by one each time, without jamming the granules.

[0025] In this embodiment, the diameter of the granules is about 3 mm, the thickness is about 2 mm, and the straight-line distance when the granules are tilted is about 3.7 mm. Therefore, the inner diameter of the sorting and feeding channel 203 is 3.8 mm, the diameter of the granule outlet 206 is 4 mm, the height is 2 mm, and the height of the reserved gap 209 is 1 mm.

[0026] Below the sorting and feeding device 200, there is a corresponding medicine receiving tank 300. The medicine receiving tank 300 is fixed on the mounting frame. The top opening of the medicine receiving tank 300 is located outside the plurality of movable pusher plates 205. Since the plurality of movable pusher plates 205 are arranged circumferentially, when the movable pusher plates 205 are extended, the medicine particles will fall downward into the medicine receiving tank 300. Therefore, the top opening of the medicine receiving tank 300 is located outside the movable pusher plates 205 in the extended state.

[0027] The receiving tank 300 is a conical tank with a narrowed bottom. A drug counter is provided at the discharge port at the bottom of the receiving tank 300. The drug counter is used to calculate the number of drug particles discharged and feed it back to the controller.

[0028] The working principle of this embodiment is as follows: Before discharge, the sorting and feeding channel 203 is filled with medicine granules in an orderly manner, waiting for the medicine granules to be discharged; when the medicine box moves to the bottom discharge port of the receiving tank 300 of this mechanism under the drive of the conveyor line, the controller receives the instruction to control the corresponding number of discharge actuators to operate, and discharge the corresponding number of medicine granules through the movable pusher plate 205, which fall into the medicine box through the medicine storage tank 100 and the medicine granule counter. The medicine box enters the next process under the drive of the conveyor line.

[0029] The device also includes a controller that controls the discharge execution quantity of the discharge actuator. The number of discharged drug particles detected by the drug particle counter is transmitted to the controller. The controller compares the detected number of discharged drug particles with the number of discharge executions. If the number of discharged drug particles is equal to the number of discharge executions, the drug particle discharge is deemed qualified. If the number of discharged drug particles is not equal to the number of discharge executions, the drug particle discharge is deemed unqualified.

[0030] As the pills pass through the pill counter, the counter detects the number of pills dispensed and sends feedback to the controller. The controller compares this number with the number dispensed by the dispensing actuator. If the numbers match, the dispensing is accurate and error-free, and the pill box continues to move to the next sorting unit. If the numbers differ, the dispensing is defective, the controller issues an alarm, and staff promptly inspect the box to determine if a dispensing actuator has malfunctioned or if pills are stuck. This feedback mechanism achieves closed-loop control.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
