[0007] The container enters the unpacking area, is unpacked manually, and then is placed in the first conveying mechanism. After the first conveying mechanism transports the container to the loading station, the container is placed in the mounting part on the turntable. Through the rotation of the turntable, the container passes through the filling station, sealing station and unloading station in sequence to complete the filling of the container. After the container is filled, the filling system of the filling station needs to be manually cleaned and sterilized. Considering the interference between the operating stations, how to reasonably arrange them? In the present invention, a loading station, a filling station, a sealing station and a discharging station are sequentially arranged on the circumference of the turntable, and then the unpacking area is arranged on the side of the discharging station, thereby avoiding interference between manual operation in the unpacking area and manual operation in the filling station. At the same time, the unpacking station is specifically arranged on the side of the discharging station to reduce the conveying distance between the unpacking station and the loading station, and reduce the conveying space. In addition, the product after filling in the discharging station is output through the second conveying mechanism, and the second conveying mechanism discharges in the direction of the first conveying mechanism. The second conveying mechanism can be arranged without adding additional space. On the whole, the various spaces on the filling device in the present invention that require manual operation will not interfere with each other, and the operation is convenient. At the same time, the space can be reasonably utilized, and the space occupancy is small.

[0008] A further technical solution of the present invention is that a partition is provided between the unpacking area and the potting area.

[0009] The partition reduces the mutual influence between the unpacking area and the filling area, ensuring a sterile environment for filling.

[0010] A further technical solution of the present invention is that a CIPSIP system is provided on the filling station.

[0011] The CIPSIP system is the abbreviation of the Cleaning and Sterilization in Place system. After filling is completed, the filling mechanism needs to be processed to ensure the cleanliness of subsequent filling; the CIPSIP system requires manual operation.

[0012] A further technical solution of the present invention is: the mounting portion comprises side plates and a limiting plate, the side plates are arranged at intervals to accommodate containers, and the limiting plate is provided with a limiting groove for limiting the container pipe mouth.

[0013] The container is placed between the side plates to accommodate the container, and the limiting grooves on the limiting plates fix the container, thereby completing the fixation of the container; the container pipe mouth is stuck in the limiting groove, and the limiting plates on both sides play a role in preventing the containers from colliding with each other and causing damage.

[0014] A further technical solution of the present invention is: a filling mechanism is provided on the filling station, the filling mechanism comprises a positioning member and a filling needle for filling, the positioning member is movable for fixing the container nozzle, and the filling needle is liftable and arranged above the container nozzle.

[0015] The positioning piece can move toward the container and form a clamping structure for fixing the container with the mounting portion, thereby ensuring the stability of the container when the filling needle fills the container and ensuring the filling accuracy.

[0016] A further technical solution of the present invention is: a welding mechanism is provided on the sealing station, and the welding mechanism includes a first linear drive guide rail and a welding head. The welding head can slide along the first linear drive guide rail to pass through the containers on the hanging belt part in sequence, and the welding head can move to both sides of the container. The welding head can be opened and closed for welding the container pipe mouth.

[0017] The welding head slides along the first linear drive guide to the container, extends to both sides of the container and then approaches each other to weld the container mouth, then returns to the first linear drive guide and continues to weld the containers on the sealing station in turn.

[0018] A further technical solution of the present invention is: a first cylinder is provided at the end of the welding head, a second cylinder is provided below the first cylinder, the second cylinder is placed on the first linear drive guide rail, and the driving direction of the first linear drive guide rail is perpendicular to the driving direction of the second cylinder.

[0019] There are two welding heads, which are moved closer to or farther away from each other through the first cylinder at the end. The second cylinder below the first cylinder can drive the first cylinder to move in a direction perpendicular to the first linear drive guide rail, so that the two welding heads can move to both sides of the container on the side of the first linear drive guide rail respectively. The second cylinder can move on the first linear drive guide rail, so that the containers on the turntable can be welded in turn.

[0020] A further technical solution of the present invention is: the discharging station is provided with a discharging mechanism and a pushing mechanism placed on the side of the container, the discharging mechanism is used to clamp the container from both sides to lift it, and the pushing mechanism is used to detach the container from the mounting portion.

[0021] After the container rotates to the unloading station, the unloading mechanism first clamps the container and then rises to weaken the gravity of the container on the mounting portion, and then the container is pushed out from the mounting portion by the pushing mechanism, which is convenient and not easy to damage the container; after the container is detached from the mounting portion, the unloading mechanism releases the container, and the container falls into the second conveying mechanism for unloading.

[0022] A further technical solution of the present invention is: the pushing mechanism includes a pushing drive and a pushing piece, the number of the pushing pieces is equal to the number of containers on the discharging station, and the pushing piece is connected to the pushing drive for the pushing piece to move in the reverse direction of the loading direction of the mounting part.

[0023] The discharging mechanism rises after clamping the container, and the pushing member pushes the container out of the mounting portion under the action of the pushing drive, and the pushing direction of the pushing member is opposite to the feeding direction of the mounting portion.

[0024] A further technical solution of the present invention is that the first conveying mechanism and the second conveying mechanism are both conveying mesh belts.

[0025] The discharging end of the second conveying mechanism is provided with a discharging area perpendicular to the second conveying mechanism, and the discharging area can be used for further processing of the filled containers.

[0026] Beneficial effects of the present invention: In the present invention, a loading station, a filling station, a sealing station and a discharging station are sequentially arranged on the circumference of the turntable, and then the unpacking area is arranged on the side of the discharging station, thereby avoiding interference between manual operation in the unpacking area and manual operation in the filling station. At the same time, the unpacking station is specifically arranged on the side of the discharging station to reduce the conveying distance between the unpacking station and the loading station, and reduce the conveying space. In addition, the product after filling at the discharging station is output through the second conveying mechanism, and the second conveying mechanism discharges in the direction of the first conveying mechanism. The second conveying mechanism can be arranged without adding additional space. On the whole, the various spaces on the filling device in the present invention that require manual operation will not interfere with each other, and are convenient to operate. At the same time, the space can be reasonably utilized, and the space occupancy is small. BRIEF DESCRIPTION OF THE DRAWINGS
