A capsule medicine dispensing machine

Abstract

This utility model relates to the field of pharmaceutical packaging technology, specifically to a capsule pharmaceutical packaging machine. This device, through precise mechanical coordination, ensures that each capsule enters its designated position independently and vertically during the packaging process. Under the continuous action of the vibrating block, the capsules are effectively dispersed and fall one by one into the first through-hole, achieving automatic and neat arrangement. This effectively avoids problems such as capsule tipping or sticking that may occur during manual operation. Subsequently, the capsules accurately fall into the second through-hole of the feeding plate. Each hole is strictly limited to accommodating only a single capsule. The feeding plate is driven by a lead screw to perform precise and controllable step-by-step movement, ensuring that only when the second through-hole moves to the predetermined position will the capsule be released due to the loss of base support. This combination of physical isolation and precise displacement fundamentally guarantees the absolute accuracy and consistency of the packaging quantity each time, greatly reducing packaging errors and achieving a high degree of automation and continuous operation.

Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging technology, and in particular to a capsule pharmaceutical packaging machine. Background Technology

[0002] Capsule filling machines are specialized equipment widely used in the pharmaceutical industry and pharmacy settings. Their main function is to separate and fill large quantities of bulk capsules into designated containers or packaging units according to specific quantity requirements. The core objective of this equipment is to achieve automatic capsule counting and filling operations, replacing tedious and error-prone manual operations and improving overall filling efficiency. Its basic workflow typically includes capsule feeding, posture adjustment, quantity measurement, and final filling into the target container. It is one of the important tools to ensure standardized and regulated drug filling production.

[0003] However, traditional capsule filling machines have a significant limitation in practical applications: they are difficult to achieve truly precise quantitative filling. Many traditional machines use volumetric methods or simple vibration feeding combined with baffles for filling. This method can only roughly control the range of capsules per batch and cannot accurately guarantee that the number of capsules output each time is constant and accurate. It is easily affected by factors such as slight differences in capsule size, fluctuations in feeding speed, or mechanical gaps, which can lead to deviations in the actual filling quantity. This uncertainty in quantity may result in drug waste or inaccurate dosage, especially in situations requiring strict quantitative filling, such as fixed-dose blister packaging or vial filling. The fuzzy control method of traditional equipment is difficult to meet the high-precision and high-reliability filling requirements. Utility Model Content

[0004] The purpose of this invention is to provide a capsule medicine filling machine that solves the problem that traditional capsule medicine filling machines cannot accurately control the quantity of medicines filled.

[0005] To achieve the above objectives, this utility model provides a capsule drug filling machine, including an operating table. A support plate is fixedly mounted on the upper surface of the operating table, a feeding hopper is fixedly mounted on the side of the support plate, a feeding mechanism is fixedly mounted on the bottom surface of the feeding hopper, and a filling mechanism is fixedly mounted on the upper surface of the operating table. The feeding mechanism includes a first motor, and the first motor is fixedly mounted on the side of the support plate away from the feeding hopper. An eccentric wheel is fixedly mounted on the output shaft end of the first motor. The operating table provides a basic support platform for the entire device, the support plate is used for vertically mounting the relevant components of the feeding mechanism, the feeding hopper is responsible for holding the capsule drugs to be filled, the feeding mechanism performs the function of vibrating conveying and arranging the capsules, the first motor provides the rotational power required by the feeding mechanism, the eccentric wheel converts the rotational motion of the first motor into motion along a specific trajectory, the guide block restricts the movement path of the movable rod to ensure its linear reciprocating motion, the movable rod transmits power through linear reciprocating motion under the constraint of the guide block, and the connecting rod connects the eccentric wheel and the movable rod to convert rotation into linear motion.

[0006] A guide block is fixedly installed on the side of the support plate away from the center, and a movable rod is movably installed inside the guide block. One end of the movable rod is connected to the eccentric wheel through a connecting rod.

[0007] The connecting rod and the eccentric wheel are connected by a rotating shaft. A vibration block is fixedly installed at the other end of the movable rod. The rotating shaft provides a rotation fulcrum for the movable connection point between the connecting rod and the eccentric wheel. The vibration block receives the reciprocating motion of the movable rod and generates directional vibration.

[0008] The vibrating block has several equidistant first through holes in the vertical direction. The vibrating block is connected to the support plate by a guide frame. The first through holes are opened on the vibrating block so that the capsules fall vertically one by one and are arranged neatly under the action of vibration. The guide frame stabilizes the movement of the vibrating block and prevents it from deviating.

[0009] The dispensing mechanism includes a second motor, which is fixedly installed at the edge of the operating table. The upper surface of the operating table is provided with a movable groove. The second motor provides the rotational power required by the dispensing mechanism, and the movable groove provides a track space for the material unloading plate to move horizontally.

[0010] The upper surface of the movable groove is movably provided with a feeding plate. The end of the feeding plate away from the second motor has a second through hole corresponding to the first through hole. The feeding plate carries the arranged capsules and performs quantitative movement. The second through hole is opened on the feeding plate to receive vertical capsules from the first through hole at the initial position. Each hole position is limited to accommodating only one capsule.

[0011] The upper surface of the operating table is fixedly provided with a base, and a feeding chute is opened on the side of the base away from the movable groove. The base supports the feeding plate and the second through hole on it in the initial position to prevent the capsule from falling off prematurely.

[0012] The operating platform is equipped with a lead screw that rotates inside. A ball nut is movably mounted on the lead screw. The ball nut is connected to the bottom of the feeding plate. The lead screw is driven to rotate by a second motor, which converts the rotational motion into linear displacement. The ball nut works in conjunction with the lead screw to precisely convert the rotational motion of the lead screw into the linear movement of the feeding plate, driving the feeding plate to slide within the movable groove.

[0013] This device, through precise mechanical coordination, ensures that each capsule enters its designated hole independently and vertically during the dispensing process. Under the continuous action of the vibrating block, the capsules are effectively dispersed and fall one by one into the first through hole, achieving automatic and neat arrangement. This effectively avoids problems such as capsule tipping or sticking that may occur during manual operation. Subsequently, the capsules accurately fall into the second through hole of the feeding plate. Each hole is strictly limited to holding only one capsule. The feeding plate is precisely controlled to move stepwise via a lead screw, ensuring that only when it moves to the predetermined position of the second through hole will the capsule be released due to the loss of base support. This combination of physical isolation and precise displacement fundamentally guarantees the absolute accuracy of the dispensing quantity each time. This device ensures accuracy and consistency, greatly reducing packaging errors and enabling highly automated and continuous operation. Its ingenious design integrates feeding and packaging functions, simplifying the operation process. Simply feed a large number of capsules into the hopper at once, start the motor, and the feeding mechanism automatically completes the vibration conveying, posture adjustment, and orderly arrangement of the capsules, continuously supplying them to the packaging station. The packaging mechanism automatically performs precise dispensing plate displacement and quantitative capsule release. The entire process, from capsule arrangement to quantitative packaging, is fully automated, eliminating the need for manual placement or intervention in the packaging process. This significantly improves packaging efficiency while reducing the labor intensity of operators, providing a solid guarantee for continuous, large-volume packaging operations.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-4 A capsule medicine dispensing machine includes an operating table 1. A support plate 2 is fixedly mounted on the upper surface of the operating table 1. A feeding hopper 3 is fixedly mounted on the side of the support plate 2. A feeding mechanism 4 is fixedly mounted on the bottom surface of the feeding hopper 3. A dispensing mechanism 5 is fixedly mounted on the upper surface of the operating table 1. The feeding mechanism 4 includes a first motor 401. The first motor 401 is fixedly mounted on the side of the support plate 2 away from the feeding hopper 3. An eccentric wheel 402 is fixedly mounted on the output shaft end of the first motor 401. The operating table 1 provides a basic installation platform and support for the entire dispensing machine. The support plate 2 is used to install and fix the relevant components of the feeding mechanism 4. The feeding hopper 3 is used to hold the capsule medicine to be dispensed. The feeding mechanism 4 is responsible for arranging and conveying the capsules in an orderly manner. The feeding mechanism 4 includes a first motor 401 that provides rotational power. The first motor 401 drives the eccentric wheel 402 to rotate. The eccentric wheel 402 converts the rotational motion into motion along a specific trajectory through its eccentric structure.

[0022] A guide block 403 is fixedly installed on the side of the support plate 2 away from the support plate. A movable rod 404 is movably installed inside the guide block 403. One end of the movable rod 404 is connected to the eccentric wheel 402 via a connecting rod 405. The connecting rod 405 and the eccentric wheel 402 are connected via a rotating shaft 406. A vibrating block 407 is fixedly installed at the other end of the movable rod 404. The vibrating block 407 has several equidistant first through holes 408 in the vertical direction. The vibrating block 407 is connected to the support plate 2 via a guide frame 409. The dispensing mechanism 5 includes a second motor 501. The second motor 501 is fixedly installed at the edge of the operating table 1. A movable groove 502 is opened on the upper surface of the operating table 1. The guide block 403 restricts the movement direction of the movable rod 404 so that it can only perform linear reciprocating motion. The movable rod 404 transmits linear reciprocating motion under the constraint of the guide block 403. The power unit, connecting rod 405, connects eccentric wheel 402 and movable rod 404, converting the rotational motion of eccentric wheel 402 into linear reciprocating motion of movable rod 404. Rotating shaft 406 provides a rotation fulcrum for the movable connection between connecting rod 405 and eccentric wheel 402. Vibration block 407 is fixed to one end of movable rod 404 and reciprocates linearly with movable rod 404 to generate directional vibration. First through hole 408 is opened on vibration block 407. Under the vibration of vibration block 407 and gravity, capsules fall vertically one by one and are arranged neatly. Guide frame 409 connects vibration block 407 and support plate 2 to stabilize the movement of vibration block 407 and prevent it from deviating. Dispensing mechanism 5 is responsible for dispensing and releasing quantitative capsules. Dispensing mechanism 5 includes a second motor 501 that provides rotational power to drive dispensing action. Movable groove 502 provides horizontal movement track space for feed plate 503.

[0023] A feeding plate 503 is movably mounted on the upper surface of the movable groove 502. A second through hole 504, corresponding to the first through hole 408, is opened at the end of the feeding plate 503 away from the second motor 501. A base 505 is fixedly mounted on the upper surface of the operating table 1. A feeding chute 506 is opened on the side of the base 505 away from the movable groove 502. A lead screw 507 is rotatably mounted inside the operating table 1. A ball nut 508 is movably mounted on the lead screw 507. The ball nut 508 is connected to the bottom of the feeding plate 503. The feeding plate 503 moves horizontally within the movable groove 502 to carry the arranged capsules. The second through hole 504 is opened on the feeding plate 503 and initially receives the capsules from the first through hole 408. Each of the vertically arranged capsules in 08 is limited to holding only one capsule in each second through hole 504. The base 505 supports the feed plate 503 and the second through hole 504 on it in the initial position, so that the capsule is temporarily held in the second through hole 504 and does not fall. The feed chute 506 is opened on the base 505. When the second through hole 504 moves above it, it receives the falling capsule and guides it to the next stage. The lead screw 507 is driven to rotate by the second motor 501. The ball nut 508 cooperates with the lead screw 507 to accurately convert the rotational motion of the lead screw 507 into its own linear motion. The ball nut 508 is connected to the feed plate 503 and drives the feed plate 503 to make precise horizontal linear movement in the movable groove 502.

[0024] Working principle: First, the operator places the capsules to be packaged into the feeding hopper 3. Then, the first motor 401 is started. The first motor 401 drives the eccentric wheel 402, which is fixed to its output shaft, to rotate. The eccentric wheel 402 transmits the rotational motion to the movable rod 404 through the connecting rod 405 connected to the rotating shaft 406. The movable rod 404 performs stable linear reciprocating motion under the constraint of the guide block 403. The movable rod 404 drives the vibrating block 407, which is fixed to it, to reciprocate synchronously. The reciprocating motion of the vibrating block 407 is transmitted through the guide frame 409 and acts on the support plate 2. Under the continuous reciprocating vibration generated by the vibrating block 407, the capsules in the feeding hopper 3 move downward in an orderly manner along the inclined surface of the feeding hopper 3 and gradually disperse. Some capsules... Under the influence of vibration and gravity, the medicine falls into multiple equidistant first through holes 408 vertically opened on the vibrating block 407. Under the continuous action of vibration and gravity, the medicine adjusts its posture within the first through holes 408, eventually arranging itself vertically. The neatly arranged capsules continue to fall, sequentially dropping out from the bottom of the first through holes 408 and into the dispensing mechanism 5 located on the upper surface of the operating table 1, specifically onto the upper surface of the base 505. At this point, the capsules are positioned above the feeding plate 503. The feeding plate 503, away from the second motor 501, has second through holes 504 corresponding to the position and size of the first through holes 408. Each second through hole 504 initially faces the upper surface of the base 505. Due to the support of the base 505, each second through hole 504... 4. It can only hold one vertically positioned capsule. The capsule temporarily remains in the second through hole 504 without falling out. When dispensing is required, the second motor 501 is started. The second motor 501 drives the lead screw 507, which is rotated inside the operating table 1, to rotate. The rotation of the lead screw 507 causes the ball nut 508 on it to move linearly along the axis of the lead screw 507. The ball nut 508 drives the feeding plate 503 connected to it to move horizontally away from the second motor 501 in the movable groove 502 opened on the upper surface of the operating table 1. As the feeding plate 503 moves, the second through hole 504 on it also moves synchronously. When the second through hole 504 moves to the feeding chute 5 opened on the side of the base 505 away from the movable groove 502... When the base 505 is above point 06, the support surface of the base 505 is interrupted at this point, and the bottom of the second through hole 504 loses support and opens. The capsule medicine originally contained in the second through hole 504 falls down under the action of gravity, slides out through the feeding chute 506, and enters the subsequent dispensing container or packaging stage. By precisely controlling the rotation angle or time of the second motor 501, the distance of each movement of the feeding plate 503 can be controlled, thereby precisely controlling how many second through holes 504 move above the feeding chute 506 each time, realizing the release of a fixed number of capsule medicines each time, and completing the quantitative dispensing operation. The entire dispensing process is coordinated by two core steps: feeding vibration arrangement and quantitative moving feeding. The feeding mechanism 4 ensures the continuous supply and orderly arrangement of capsule medicines.The five dispensing mechanisms enable precise release of quantitatively measured capsule medications.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
