Description

Technical Field

[0001] This utility model relates to the field of silo docking, specifically a silo adaptive docking device. Background Technology

[0002] Powder silos are used to temporarily store powder materials and connect to upstream and downstream equipment, such as crushers, mixers, and packaging machines, to achieve continuous material transfer. They are commonly found in clean production environments in the pharmaceutical industry and must meet the requirements of sterility, dust prevention, and prevention of cross-contamination.

[0003] For example, Chinese Patent Publication No. CN115676440A discloses a fully enclosed material feeding and docking system, which relates to the field of material feeding equipment. It includes: a batching and receiving module, which is set on the top of the powder silo and is used to fill the powder silo with filler; the powder silo, which is used to receive the material from the batching and receiving module and deliver the received material to a predetermined work station; a feeding mechanism, which is used to dock with the powder silo to perform the feeding process; and a transfer module, which is used to move the powder silo to a predetermined position.

[0004] In summary, the existing silo connection method has many drawbacks, which are summarized as follows:

[0005] ① The existing silo docking device has unsanitary blind spots, and the forced positioning of the docking device causes material friction, which may generate metal foreign objects;

[0006] ② Due to the unevenness of the ground or the positioning accuracy required when AGV is handling, a flexible structure is needed to accommodate these size differences. However, the docking structure in the above patent document does not have a flexible design for the hopper, which can easily cause impact damage during docking.

[0007] ③ In addition, if a moving track is set in the docking structure, powder can easily get into the gaps or track surface in the working environment, causing pollution. Utility Model Content

[0008] To address the shortcomings of existing technologies, this invention provides an adaptive docking device for silos to solve the aforementioned problems.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0010] A silo adaptive docking device includes a displacement docking device and a docking support, wherein the displacement docking device is connected to the docking support.

[0011] The displacement docking device includes a front and rear side displacement device, a telescopic device, an upper and lower side displacement device, a docking transmission device, and a buffer device. One end of the telescopic device is fixed on the docking bracket, and the other end is connected to the front and rear side displacement device. The upper and lower side displacement device is connected to the front and rear side displacement device. The docking transmission device is connected to the upper and lower side displacement device through the buffer device.

[0012] Preferably, the buffer device includes a buffer connecting plate, a buffer limiting plate, a buffer film, a buffer built-in plate, a buffer spring assembly, and a buffer guide rail assembly. The buffer limiting plate is connected to both sides of the buffer connecting plate. The buffer film is located between the buffer built-in plate and the buffer connecting plate. The buffer film extends from both ends of the buffer built-in plate and connects to the buffer connecting plate. The buffer spring assembly is provided with a buffer center connector, which is connected to the buffer built-in plate. The buffer guide rail assembly is slidably connected to the buffer built-in plate. The docking end of the docking transmission device first contacts the pipe of the hopper, and its flared opening shape cooperates with the buffer spring assembly in the buffer device. A dual-buffer system is formed to avoid frictional damage to materials caused by forced positioning and reduce the generation of metal foreign objects. The system utilizes five components—front and rear displacement devices, telescopic devices, upper and lower displacement devices, docking and transmission devices, and buffer devices—to coordinate and complete the forward, backward, up, and down displacement and buffering actions. This replaces the previous method of determining the docking position solely by the lifting and lowering of the AGV trolley, thus reducing impact during docking. Front and rear thin films, upper and lower thin films, and buffer films are respectively placed on the tracks requiring displacement, such as the front and rear transmission components, upper and lower transmission components, and buffer guide rail components. This ensures that the displacement action is not affected and prevents powder from falling into the moving structure, causing displacement jamming and contamination.

The front and rear driving device is connected to the front and rear connecting structure. The front and rear connecting structure includes a front and rear connecting platform and a front and rear limiting plate.

[0023] ① The docking end of the docking transmission device first contacts the pipe of the silo. Its flared opening shape, together with the buffer spring group in the buffer device, forms a double buffering form to avoid frictional damage to the material caused by forced positioning and reduce the generation of metal foreign objects.

[0024] ② The front and rear displacement devices, telescopic devices, upper and lower displacement devices, docking and transmission devices, and buffer devices work together to complete the front and rear and upper and lower displacement and buffering actions, which replaces the original situation where the docking position was determined solely by the lifting and lowering of the AGV trolley, and also reduces the impact during docking.

The upper and lower displacement device 13 includes upper and lower cylinders 131, upper and lower transition plates 132, upper and lower transmission devices 133, and upper and lower connecting plates 134. The upper and lower cylinders 131 are fixed on the upper and lower connecting plates 134, and the telescopic ends of the upper and lower cylinders 131 are connected to the upper and lower transition plates 132.

The transmission movable plate 142 is hinged to the output end of the docking transmission device 14, and its opening and closing direction is limited to the side facing the output end. The docking end of the docking transmission device 14 has a flared outer opening, which is used in this design, but other opening shapes are also possible, as long as the maximum diameter is larger than the diameter of the transmission pipe of the docking transmission device 14. The purpose is to ensure smooth docking. A rubber inflation ring is installed inside the air bladder groove 141, and an inflation / deflation nozzle is installed on the outside.

[0043] When work begins, such as Figure 10The AGV shown will transport the hopper to the designated docking position, then lower the hopper and attach it to the docking bracket 2. Subsequently, the upper and lower cylinders 131 drive the upper and lower transition plates 132 to move upward under the limiting action of the upper and lower transmission devices 133, so that the docking transmission device 14 is aligned with the axis of the hopper's pipe outlet. Then, the front and rear cylinders 122 drive the upper and lower connecting plates 134 to move forward. The docking end of the docking transmission device 14 first contacts the hopper's pipe. The trumpet-shaped opening shape and the buffer spring group 155 in the buffer device 15 form a double buffer. After the hopper's pipe is docked in place, the rubber inflatable ring in the airbag groove 141 begins to inflate, so that the outer wall of the hopper's pipe is relatively sealed with the outer wall of the docking transmission device 14. The transmission movable plate 142 can prevent backflow when the transmission work is stopped. After the transmission process is completed, the operation can be repeated in reverse, and so on.
