Description

Technical Field

[0001] This utility model relates to the field of chemical and pharmaceutical production technology, specifically a cross-layer vertical feeding system suitable for solid dosage form production. Background Technology

[0002] In the chemical and pharmaceutical manufacturing industries, the closed-loop transfer of materials has always been a tedious, crucial, and labor-intensive production process. The transfer of materials from one production area to another affects the transfer speed, the physical labor of personnel, and the production efficiency of equipment. This is especially true for large-scale material transfers, which pose a challenge to the entire cleanroom environment. Cross-contamination, mixing, and heavy manual labor are problems that arise during transfer. Previously, material transfer relied primarily on manual labor or container transport, requiring constant personnel involvement. This vertical drop conveyor system perfectly solves the problem of wasted human and physical resources, achieving unmanned and intelligent operation. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a cross-layer vertical material feeding system suitable for solid dosage form production. It achieves automated conveying of drugs to be packaged, enabling operation across regions, floors, and equipment. Furthermore, its enclosed design eliminates the risks of leakage, mixing, and cross-contamination during the conveying process, thus saving manpower while achieving safe, efficient, and unmanned material handling.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A multi-layer vertical feeding system suitable for solid dosage form production includes: Stainless steel pipes are installed, extending vertically. A silicone tube is fitted inside a stainless steel tube, with both ends of the silicone tube being sealed to the corresponding ends of the stainless steel tube, thereby forming an annular sealed gap between the silicone tube and the stainless steel tube. PE pipe, inserted inside silicone pipe; The air inlet and air outlet are respectively located on the wall of the stainless steel pipe and connected to the annular sealed gap.

[0005] Furthermore, a material tank is connected to the upper end of the stainless steel pipe, and the material tank is designed to be movable.

[0006] Furthermore, the upper end of the stainless steel pipe is connected to the material tank via a flexible connector.

[0007] Furthermore, the position of the material tank is determined by a guide positioning plate.

[0008] Furthermore, a level gauge for detecting material level is installed at the upper end of the stainless steel pipe.

[0009] Furthermore, a respirator for balancing pressure is installed at the upper end of the stainless steel tube.

[0010] Furthermore, the lower end of the stainless steel pipe is equipped with a clamp joint for connecting downstream equipment.

[0011] The beneficial effects of this utility model are: (1) The start and stop control of the material in the PE pipe is achieved by controlling the air pressure of the silicone tube. When the material needs to fall, the silicone tube is depressurized and the material falls by gravity; when the material needs to be stopped, air is introduced into the silicone tube to pressurize it, causing it to expand and compress the PE pipe, thereby stopping the material. In addition, an airbag is formed during the falling process to ensure that the material is transported without damage over a height difference of about 4 meters.

[0012] (2) It realizes the automated conveying of medicines to be packaged and supports seamless operation across regions, floors and equipment. Its fully enclosed design can effectively prevent leakage, confusion and cross-contamination during the conveying process, while greatly saving manpower and ensuring the safety and efficiency of material flow.

[0013] (3) Automated and closed-loop material transport between clean areas has been achieved. The material starts from the clean area, passes through the general area, and is safely delivered to another clean area in a closed environment throughout the process, effectively eliminating the risk of leakage, confusion and cross-contamination, and realizing unmanned operation.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1-3As shown, a cross-floor vertical material feeding system suitable for solid dosage form production includes a stainless steel pipe 7 extending vertically. In a specific embodiment, the stainless steel pipe 7 passes vertically through the floor slab, enabling material transport between floors. A silicone tube 8 is fitted inside the stainless steel pipe 7, with both ends of the silicone tube 8 sealed to the corresponding ends of the stainless steel pipe 7, forming an annular sealed gap between the silicone tube 8 and the stainless steel pipe 7. The silicone tube 8 is elastic. A PE tube 6 passes inside the silicone tube 8. The PE tube 6 has a low coefficient of friction, facilitating material transport. During material transport, the material is conveyed downwards in free fall along the inner wall of the PE tube 6, with the silicone tube 8 responsible for inflation and buffering to control the falling speed. An inflation port 9 and an exhaust port 10 are respectively located on the wall of the stainless steel pipe 7 and connected to the annular sealed gap. Through the inflation port 9, the annular sealed gap formed between the silicone tube 8 and the stainless steel pipe 7 can be pressurized and inflated, causing the silicone tube 8 to expand and press against the PE tube 6, thereby blocking the material flow. The pressure is released and the air is vented through the vent 10 through the annular sealed gap formed between the silicone tube 8 and the stainless steel tube 7, and the material inside the PE tube 6 falls down by gravity.

[0019] The upper end of the stainless steel pipe 7 is connected to a material tank 1, which is a movable structure. The position of the material tank 1 is determined by a guide positioning plate 2. The upper end of the stainless steel pipe 7 is connected to the material tank 1 via a flexible connection 3, allowing the material in the material tank 1 to enter the stainless steel pipe 7.

[0020] A level gauge 4 for detecting material level is installed at the upper end of the stainless steel pipe 7, and a breather 5 for balancing pressure is also installed at the upper end of the stainless steel pipe 7. The level gauge 4 can detect the material and control the falling speed of the material. The breather 5 serves to balance the air pressure inside the pipe.

[0021] The lower end of the stainless steel pipe 7 is provided with a clamp joint 11 for connecting downstream equipment. The stainless steel pipe 7 is connected to other equipment through the clamp joint 11, so that the material in the stainless steel pipe 7 can enter other equipment.

[0022] In practice, the start and stop of material flow within the PE pipe 6 are controlled by adjusting the air pressure in the silicone tube 8. When material needs to fall, the silicone tube 8 is depressurized, and the material falls under gravity. When material needs to be stopped, air is introduced into the silicone tube 8 to increase its pressure, causing it to expand and compress the PE pipe 6, thereby stopping the material flow. Furthermore, during the descent, the silicone tube 8 forms an airbag buffer, ensuring undamaged material transport over a height difference of approximately 4 meters.

[0023] This system automates the transport of pharmaceuticals awaiting packaging, supporting continuous and seamless operation across areas, floors, and equipment. The system employs a fully enclosed design, ensuring that materials remain sealed throughout the transport process, effectively preventing leakage, mixing, and cross-contamination. Materials originate from the cleanroom, pass through general production areas, and safely arrive at the target cleanroom, requiring no manual intervention throughout the entire process. This achieves automated and sealed flow between cleanrooms. This transport method significantly saves manpower while ensuring the safety and high efficiency of material flow, eliminating the risk of contamination.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
