Description

Technical Field

[0001] This application relates to the field of pharmaceutical manufacturing equipment technology, specifically a fully automated hard capsule filling device. Background Technology

[0002] In the pharmaceutical manufacturing industry, hard capsule filling is a crucial step. While traditional hard capsule filling equipment can achieve a certain degree of automation, there is still room for improvement in filling accuracy, production efficiency, and equipment stability. With the rapid development of the pharmaceutical industry, the requirements for hard capsule filling equipment are also increasing.

[0003] An existing patent (publication number: CN210020394U) discloses a fully automatic hard capsule filling device, including a chassis and a frame fixedly installed on the upper part of the chassis. A rotating filling seat is mounted on the upper surface of the chassis, and a capsule placement block is mounted on the side wall of the rotating filling seat. Multiple capsule placement slots are provided on the upper surface of the capsule placement block. A dust suction hood is installed on the sealing cover of the capsule placement block, and a drug-blocking mesh is installed on the inner wall of the dust suction hood. The dust suction hood moves up and down via an electro-hydraulic actuator. The beneficial effect is that the fully automatic hard capsule filling device of this invention can directly suction air from the capsule placement slots, thus ensuring that the powder in the capsule placement slots is completely removed, avoiding residual powder in the capsule placement slots, resulting in thorough powder cleaning and good practicality.

[0004] While the devices described in the aforementioned comparative documents can prevent residual powder in the capsule container, they cannot perform quality inspection on the filled hard capsules or automatically remove defective products. To address these issues, a fully automatic hard capsule filling device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a fully automated hard capsule filling device that utilizes photoelectric sensors in conjunction with pneumatic rejection components to achieve low-cost quality inspection, automatically reject unqualified products, and ensure the quality of the final product.

[0006] To achieve the above objectives, this application provides the following technical solution: a fully automatic hard capsule filling device, comprising a frame, a rotating capsule filling seat assembly, a capsule supply assembly, a powder filling assembly, a finished product output assembly, and a quality inspection assembly. The quality inspection assembly includes a fixed plate fixedly connected to the outer surface of the frame. A discharge hopper, a small conveying assembly, and a first cylinder are fixedly connected to the upper surface of the fixed plate. A deceleration channel is fixedly connected to the output end of the discharge hopper. A vibrator is fixedly connected to the bottom surface of the deceleration channel. Two baffles are fixedly connected to the upper surface of the small conveying assembly. A rejection plate and a protective plate are slidably connected to the inner walls of the two baffles, respectively. A photoelectric sensor is installed directly above the baffles. A defective discharge port is opened on the upper surface of the fixed plate.

[0007] A guide rail is fixedly connected to the upper surface of the baffle, and a guide block is slidably sleeved on the inner wall of the guide rail. A first L-shaped plate and a second L-shaped plate are fixedly connected to both sides of the guide block, and the output end of the first cylinder is fixedly connected to the outer surface of the second L-shaped plate.

[0008] The above scheme utilizes a quality inspection component to perform quality checks on the capsules output from the finished product output component. This automatically removes defective products, ensuring the quality of the finished product. During the inspection process, the vibrator and the first cylinder are activated. The vibrator causes the capsules in the discharge hopper to move towards the deceleration channel. The first cylinder drives the guide block to reciprocate along the inner wall of the guide rail. Each reciprocating motion of the guide block causes the first and second L-shaped plates to separate a capsule from the discharge hopper and transport it through the deceleration channel. Each capsule output through the deceleration channel falls sequentially into the small conveying component. Then, a photoelectric sensor detects the closure status of each capsule. Combined with the rejection plate and the protective plate, this achieves automatic rejection of defective products, ensuring the quality of the finished product.

[0009] Furthermore, the rotating capsule filling assembly, capsule supply assembly, powder filling assembly, and finished product output assembly are all mounted on the upper surface of the frame. Two support rods are fixedly connected to the upper surface of the fixing plate, and the top ends of the two support rods are fixedly connected to the bottom surface of the finished product output assembly.

[0010] The above solution, through the addition of support rods, can improve the stability of the finished product output components and optimize the actual usage effect.

[0011] Furthermore, the output end of the finished product output component is connected to the input end of the discharge hopper, the input end of the deceleration channel is connected to the output end of the discharge hopper, and the output end of the deceleration channel is connected to the input end of the small conveying component.

[0012] The above scheme allows for convenient delivery of filled capsules via the finished product output component. The filled capsules are then transported to the discharge hopper via the finished product output component. The capsules in the discharge hopper are then conveyed via a deceleration channel. The capsules in the deceleration channel are then conveyed via a small conveying component, where quality inspection is performed.

[0013] Furthermore, two second cylinders are fixedly connected to the upper surface of the fixing plate, and the output shaft ends of the two second cylinders are fixedly connected to the sides of the rejection plate and the protective plate that are far apart from each other.

[0014] With the above scheme, when the two second cylinders are started, they will drive the rejection plate and the protective plate to move respectively, which will facilitate the automatic rejection of unqualified capsules.

[0015] Furthermore, a discharge channel is installed below the non-conforming discharge port, and a placement plate is fixedly connected to the outer surface of the frame. The upper surface of the placement plate is provided with a non-conforming collection box and a conforming collection box.

[0016] With the above scheme, the defective capsules that fall into the defective discharge port will be transported to the designated location through the discharge channel. The placement plate can be used to conveniently and stably place the defective collection box and the qualified collection box.

[0017] Furthermore, magnetic absorbing plates A are fixedly connected to the bottom surfaces of both the unqualified collection box and the qualified collection box, and two magnetic absorbing plates B are fixedly connected to the upper surface of the placement plate, with magnetic absorbing plates A and magnetic absorbing plates B being compatible.

[0018] The above scheme uses magnetic plates A and B to magnetically attach unqualified and qualified collection boxes to the upper surface of the placement plate, thereby ensuring the stability of the unqualified and qualified collection boxes when collecting capsules.

[0019] Furthermore, the output end of the discharge channel is adapted to the unqualified collection box, and the output end of the small conveying component is adapted to the qualified collection box.

[0020] With the above solution, unqualified capsules conveyed in the discharge channel will fall into the unqualified collection box, while qualified capsules output from the small conveying component will be conveyed to the qualified collection box, thus enabling convenient classification and processing of qualified and unqualified capsules.

[0021] Furthermore, a main controller is fixedly connected to the outer surface of the frame, and the electrical components inside the frame, the rotating capsule filling seat assembly, the capsule supply assembly, the powder filling assembly, the finished product output assembly, and the quality inspection assembly are all electrically connected to the main controller.

[0022] The above scheme allows for convenient control of the electrical components in the device via a central controller, simplifying the operation process.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects: This fully automatic hard capsule filling equipment uses a quality inspection component to inspect the capsules output from the finished product output component. It automatically rejects defective products, ensuring product quality. During the inspection process, a vibrator and a first cylinder are activated. The vibrator moves the capsules in the discharge hopper towards the deceleration channel. The first cylinder drives a guide block to reciprocate along the inner wall of the guide rail. Each reciprocating motion of the guide block causes the first and second L-shaped plates to separate one capsule from the discharge hopper, which is then conveyed in the deceleration channel. This achieves precise separation of individual capsules, ensuring the continuity and stability of the inspection process. Each capsule output from the deceleration channel falls sequentially into a small conveying component. A photoelectric sensor detects the closure status of each capsule. Combined with the second cylinder, rejection plate, and protective plate, this system automatically rejects defective products, ensuring product quality. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of a fully automatic hard capsule filling device includes a frame 1, a rotating capsule filling seat assembly 2, a capsule supply assembly 3, a powder filling assembly 4, a finished product output assembly 5, and a quality inspection assembly 6. The rotating capsule filling seat assembly 2, capsule supply assembly 3, powder filling assembly 4, and finished product output assembly 5 are all mounted on the upper surface of the frame 1. The quality inspection assembly 6 includes a fixing plate 601 fixedly connected to the outer surface of the frame 1. Two support rods 623 are fixedly connected to the upper surface of the fixing plate 601, and the top ends of the two support rods 623 are fixedly connected to the bottom surface of the finished product output assembly 5. The support rods 623 improve the stability of the finished product output assembly 5 and optimize the actual usage effect. A discharge hopper 60 is fixedly connected to the upper surface of the fixing plate 601. 2. The small conveying component 605 and the first cylinder 611 are connected to the output end of the discharge hopper 602, which is fixedly connected to the deceleration channel 603. The output end of the finished product output component 5 is connected to the input end of the discharge hopper 602, the input end of the deceleration channel 603 is connected to the output end of the discharge hopper 602, and the output end of the deceleration channel 603 is connected to the input end of the small conveying component 605. The finished product output component 5 can conveniently convey the filled capsules, which will be conveyed to the discharge hopper 602 through the finished product output component 5. The capsules in the discharge hopper 602 will be conveyed through the deceleration channel 603, and the capsules in the deceleration channel 603 will be conveyed through the small conveying component 605, where quality inspection will be performed.

[0028] Please see Figure 2 , Figure 3 and Figure 4A vibrator 604 is fixedly connected to the bottom surface of the deceleration channel 603. When the vibrator 604 is activated, the deceleration channel 603 vibrates, thereby conveying the capsules in the discharge hopper 602 into the deceleration channel 603 for further conveying. Two baffles 606 are fixedly connected to the upper surface of the small conveying assembly 605. A rejection plate 614 and a protective plate 615 are slidably connected to the inner walls of the two baffles 606, respectively. Two second cylinders 613 are fixedly connected to the upper surface of the fixed plate 601. The output shaft ends of the two second cylinders 613 are fixedly connected to the opposite sides of the rejection plate 614 and the protective plate 615. When the two second cylinders 613 are activated, they will drive the rejection plate 614 and the protective plate 615 to move, thereby facilitating the automatic rejection of unqualified capsules. A photoelectric sensor 612 is installed directly above the baffle 606. By setting the photoelectric sensor 612, the closing state of the capsule conveyed by the small conveying assembly 605 below can be detected. Please see Figure 3 , Figure 4 and Figure 5 The upper surface of the fixed plate 601 has a defective discharge port 616, and a discharge channel 617 is installed below the defective discharge port 616. A placement plate 618 is fixedly connected to the outer surface of the frame 1. The upper surface of the placement plate 618 has a defective collection box 619 and a qualified collection box 620. Defective capsules that fall into the defective discharge port 616 will be transported to a designated position through the discharge channel 617. The placement plate 618 can conveniently and stably place the defective collection box 619 and the qualified collection box 620. The bottom surface of the defective collection box 619 and the qualified collection box 620 are fixedly connected to magnetic suction pieces A621. The upper surface of the placement plate 618 is fixedly connected to two magnetic suction pieces B622. 1. Adapted to magnetic suction plate B622, the magnetic suction plates A621 and B622 can magnetically attract the unqualified collection box 619 and the qualified collection box 620 to the upper surface of the placement plate 618, thereby ensuring the stability of the unqualified collection box 619 and the qualified collection box 620 when collecting capsules. The output end of the discharge channel 617 is adapted to the unqualified collection box 619, and the output end of the small conveying component 605 is adapted to the qualified collection box 620. The unqualified capsules conveyed in the discharge channel 617 will fall into the unqualified collection box 619, and the qualified capsules output from the small conveying component 605 will be conveyed to the qualified collection box 620, thereby facilitating the classification and processing of qualified and unqualified capsules.

[0029] Please see Figure 1 , Figure 2 and Figure 4A guide rail 607 is fixedly connected to the upper surface of the baffle 606. A guide block 608 is slidably sleeved on the inner wall of the guide rail 607. A first L-shaped plate 609 and a second L-shaped plate 610 are fixedly connected to both sides of the guide block 608, respectively. The first L-shaped plate 609 and the second L-shaped plate 610 are slidably sleeved on both sides of the deceleration channel 603. The output end of the first cylinder 611 is fixedly connected to the outer surface of the second L-shaped plate 610. When the first cylinder 611 is started, it drives the second L-shaped plate 610 to reciprocate. Through the reciprocating movement of the second L-shaped plate 610, and in conjunction with the guide rail 607 and the guide block 608, It can drive the first L-shaped plate 609 to move back and forth. Each time the guide block 608 moves back and forth, a capsule can be transported through the deceleration channel 603, thereby enabling the detection of the closure status of each capsule, which is more practical. The outer surface of the frame 1 is fixedly connected to the main controller 7. The electrical components inside the frame 1, the rotating capsule filling seat assembly 2, the capsule supply assembly 3, the powder filling assembly 4, the finished product output assembly 5, and the quality detection assembly 6 are all electrically connected to the main controller 7. The main controller 7 can be used to conveniently control the electrical components in the device, simplifying the operation process.

[0030] In this embodiment, a fully automatic hard capsule filling device, through a quality inspection component 6, can perform quality inspection on the capsules output from the finished product output component 5, automatically rejecting unqualified products to ensure the quality of the finished product. During the inspection process, the vibrator 604 and the first cylinder 611 are activated. The activation of the vibrator 604 causes the capsules in the discharge hopper 602 to move towards the deceleration channel 603. The activation of the first cylinder 611 drives the guide block 608 to reciprocate along the inner wall of the guide rail 607. At this time, the guide block 608 reciprocates by one step. Each round trip can drive the first L-shaped plate 609 and the second L-shaped plate 610 to separate a capsule from the discharge hopper 602 and convey it in the deceleration channel 603, achieving the effect of precise separation of individual capsules and ensuring the continuity and stability of the detection process. Each capsule output through the deceleration channel 603 will fall into the small conveying component 605 in sequence, and then the closure status of each capsule will be detected by the photoelectric sensor 612. Combined with the second cylinder 613, the rejection plate 614 and the protective plate 615, the unqualified products will be automatically rejected to ensure the quality of the finished product.

[0031] The working principle of the above embodiment is as follows: After the equipment is started, empty capsules are conveyed by the capsule supply component 3 through the rotating capsule filling seat component 2, and then the empty capsules are filled by the powder filling component 4. Finally, the finished product output component 5 conveys the filled capsules to the discharge hopper 602, and then drives the vibrator 604 and the first cylinder 611 to work. When the vibrator 604 is started, the capsules can enter the deceleration channel 603 in an orderly manner from the discharge hopper 602. The first cylinder 611 pushes the guide block 608 to reciprocate along the guide rail 607, which drives the first L-shaped plate 609 and the second L-shaped plate 610 to periodically separate individual capsules to the small conveying group. The capsules are fed into the small conveying assembly 605. The photoelectric sensor 612 then monitors the closure status of the capsules on the small conveying assembly 605 in real time. If an unclosed or damaged capsule is detected, the two corresponding second cylinders 613 immediately drive the rejection plate 614 and the protective plate 615 to push the defective capsules into the defective discharge port 616. The capsules then fall into the defective collection box 619, which is magnetically fixed above the placement plate 618, through the discharge channel 617. The qualified capsules continue to slide along the small conveying assembly 605 into the qualified collection box 620. This process can accurately detect the quality of the capsules, which can significantly improve production efficiency and product qualification rate while ensuring high-precision filling and stable quality.
