Description

Technical Field

[0001] This utility model belongs to the field of capsule processing technology, specifically a capsule turning device for capsule processing. Background Technology

[0002] In the production of traditional Chinese medicine capsules, capsules such as Gujinwan, Zhenqi Jiangtang, Shenling Tongluo, and Yandan Yixin occupy an important position in the pharmaceutical market due to their unique formulas and significant clinical efficacy. During the processing and production of these capsules, the orientation of the capsules is strictly required. The correct orientation of the capsules directly affects the accuracy of subsequent filling, sealing and other processes and the finished product qualification rate. However, in the actual capsule transportation process, due to the slight differences in the weight distribution of the capsules, the orientation can easily become disordered, which in turn affects the quality stability and production efficiency of the medicine.

[0003] Currently, existing capsule turning devices on the market generally suffer from technical defects such as complex structure, low turning efficiency, and poor stability. For formulations like Gujinwan Capsules and Zhenqi Jiangtang Capsules, which have extremely high requirements for sealing and appearance consistency, traditional devices cannot accurately control the posture of the finished capsules. During the sealing process, this often leads to misalignment between the capsule cap and the capsule body, resulting in gaps or incomplete sealing. This not only reduces product sealing but may also lead to misjudgments in quality inspection due to appearance defects. For example, weight detection data may fluctuate due to capsule orientation deviation, and sealing tests may fail due to abnormal capsule placement. For products with stringent packaging specifications, such as Shenling Tongluo Capsules and Yandan Yixin Capsules, disordered capsule orientation will prevent automated packaging equipment from accurately positioning, resulting in misaligned boxes, incorrect placement of instructions, etc., seriously affecting packaging efficiency and significantly reducing the finished product qualification rate.

[0004] Even more challenging is that existing technologies are insufficient to meet the urgent need for large-scale production of finished Chinese medicine capsules. On the one hand, relying on manual intervention to adjust the capsule orientation is costly and inefficient, making it unsuitable for production scales of tens of thousands or even higher per day. On the other hand, traditional equipment lacks stability and is prone to jamming due to capsule orientation confusion during prolonged operation, leading to frequent downtime for maintenance and severely disrupting production continuity.

The telescopic end of the electric telescopic rod 12 is fixedly connected to the arc-shaped top 13. The arc-shaped top 13 is used in conjunction with the corresponding placement mechanism 2. The upper end of the belt conveyor 14 is fixedly connected to the ejection mechanism. The ejection mechanism is used in conjunction with the separation mechanism. The separation mechanism is fixedly connected to the frame of the belt conveyor 14. An electric telescopic rod 3 21 is provided on the belt conveyor 14. The electric telescopic rod 3 21 is used in conjunction with the corresponding placement mechanism 2.

[0027] Each of the placement mechanisms 2 includes a base plate 3, a slide rail 4, a placement plate 5, and multiple placement holes 22;

[0028] The base plate 3 is fixedly connected to the conveyor belt of the circular conveyor 1. The lower end of the placement plate 5 is connected to the upper end of the base plate 3 through the slide rail 4. The placement plate 5 is provided with a plurality of placement holes 22 in an array.

[0029] The launching mechanism includes a fixed frame 15, an electric telescopic rod 16, a lifting plate 17, and multiple top columns 18.

[0030] The fixed frame 15 is fixedly connected to the belt conveyor 14. The top end of the fixed frame 15 is fixedly connected to the fixed end of the electric telescopic rod 16. The telescopic end of the electric telescopic rod 16 is fixedly connected to the upper end of the lifting plate 17. The lower end of the lifting plate 17 is provided with a plurality of top columns 18, and the plurality of top columns 18 correspond one-to-one with the plurality of placement holes 22 on the corresponding placement plate 5.

[0031] The separation mechanism includes a fixed frame 19 and multiple partitions 20;

[0032] The fixed frame 19 is fixedly connected to the belt conveyor 14. Multiple partitions 20 are evenly distributed on the lower end face of the fixed frame 19, and the multiple partitions 20 are correspondingly arranged with multiple top columns 18.

[0033] This capsule turning device for capsule processing achieves capsule screening, posture adjustment, and conveying through the coordinated operation of multiple components. Its working principle is as follows:

[0034] 1. Preliminary screening and placement of capsules: The capsules to be processed are poured into the drug delivery chamber 6. The bottom of the drug delivery chamber 6 slides against the placement plate 5 of the placement mechanism 2. Under the action of gravity, the capsules slide along the inclined plate 7 to the placement plate 5. The placement plate 5 is provided with multiple placement holes 22 that match the shape and size of the capsules. Taking advantage of the fact that the diameter of the capsule cap is larger than that of the capsule body, qualified capsules can fall smoothly into the placement holes 22. Capsules with incorrect posture or incorrect size remain on the surface of the placement plate 5 (some placement holes 22 are allowed to be empty). At this time, the external power supply starts the motor 10. The motor 10 drives the brush roller 9 to rotate. The brush bristles throw out the unqualified capsules on the surface of the placement plate 5, ensuring that the capsules in the placement holes 22 have the correct posture and are qualified, thus completing the preliminary screening.

[0035] 2. Capsule transfer and pushing: The circular conveyor 1 is driven by a motor to drive the chain or belt to continuously rotate, which drives the capsule placement mechanism 2 to move. When the placement mechanism 2 rotates to the point where the belt conveyor 14 connects with the circular conveyor 1, it is preferable to use a PLC controller to control the circular conveyor 1 to stop running and start the belt conveyor 14 at the same time. Then, the electric telescopic rod 12 extends, and the arc-shaped top 13 at its telescopic end pushes the placement plate 5 on the capsule placement mechanism 2 above the separation mechanism.

[0036] III. Capsule Separation and Conveying: Preferably, a PLC controller is used to control the electric telescopic rod 16 to move downwards, and the lifting plate 17 fixed at its telescopic end descends accordingly. Multiple top posts 18 at the lower end of the lifting plate 17 correspond one-to-one with the placement holes 22 on the placement plate 5. Capsules in the correct posture in the placement holes 22 are pushed into the corresponding two partitions 20. The top posts 18 are made of a material with a certain hardness and wear resistance, and the ends are smooth to avoid damaging the capsules. The partitions 20 of the separation mechanism provide a stable conveying channel for the capsules, preventing the capsules from changing their posture during the conveying process and ensuring that the capsules are stably conveyed to the next process in the correct posture.

[0037] IV. Placement Mechanism Reset and Cycle: After the capsule is pushed out, it is preferable to use a PLC controller to control the electric telescopic rod 21 to push the placement mechanism 2 back onto the conveyor belt of the circular conveyor 1. The action of the electric telescopic rod 21 ensures that the placement mechanism 2 is accurately reset. Then, the circular conveyor 1 continues to operate and enters the next working cycle.

[0038] By using a PLC controller to precisely control the actions of components such as the circular conveyor 1, belt conveyor 14, motor 10, electric telescopic rod 12, electric telescopic rod 26, and electric telescopic rod 31 according to a predetermined program, the PLC controller's programming interface allows for flexible setting of parameters such as the action time, sequence, and delay of each component, ensuring efficient and stable operation of the device. The preferred PLC controller is the Siemens S7-200 SMART or Omron CP series PLC.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
