[0041] like image 3 As shown, the liquid filling device includes a storage tank 42, and the storage tank 42 is provided with a ventilation hole 44, a liquid level gauge 43 and a pneumatic valve 41 for inputting liquid, such as Figure 4 As shown, twelve infusion tubes 37 communicating with the storage box 42 are arranged side by side under the storage box 42, a filling nozzle 39 is installed at the lower end of the infusion tube 37, and a container righting is installed on the filling nozzle 39. Positioner 35, the inner hole of the container centering positioner 35 is an inverted funnel shape, which plays the purpose of centering and positioning the container. A ball valve 36 and a solenoid valve 34 are installed between the infusion pipe 37 and the storage tank 42. The pneumatic valve 23 is mounted on the pipe 37 .
[0042] like Figure 5 As shown, the lower part of the storage box 42 is provided with a filling nozzle line changing device, and the filling nozzle line changing device includes a filling nozzle line changing carriage 20, and two filling nozzle changers are arranged transversely on the frame 31. The line trolley track 30, the filling nozzle line changing trolley 20 can slide back and forth along the filling nozzle line changing trolley track 30 through the bearing 19, and a side of the filling nozzle line changing trolley 20 can push The filling nozzle line changing carriage 20 slides the execution cylinder 27 and the execution cylinder 28. Positioning sensors 24 and 25 are respectively provided at the positions on both sides of the filling nozzle wire changing carriage 20 to control the filling nozzle during changing. When the line is in the corresponding position with the bottle body on the second conveyor belt B or the third conveyor belt C, the filling nozzle mounting frame 26 for fixing the filling nozzle 39 is provided on the filling nozzle line changing carriage 20. The filling nozzle The mounting frame 26 is adjusted up and down through the height adjustment screw 21 of the filling nozzle, the height adjustment screw 33 of the filling nozzle, the filling nozzle lifting cylinder 22 and the filling nozzle lifting cylinder 29, which are respectively installed at both ends thereof, so as to adapt to different heights. High bottle body.
[0043] During operation, the first conveyor belt drive motor 32 is activated to drive the first conveyor belt A to rotate, and the second conveyor belt drive motor 16 and the third conveyor belt drive motor 17 are activated to drive the second conveyor belt B and the third conveyor belt C to rotate, respectively. At this time, the bottle baffle cylinder 2 is in an open state, and the bottle baffle cylinder 3 is in a bottle blocking state. When the bottle body passes through the photoelectric sensor 1 and counts to the set value in turn, the bottle body baffle cylinder 2 acts to block the bottle, so that the bottle body before and after the bottle body baffle cylinder 2 is separated by a distance, and then the bottle body baffle cylinder 2 is passed through the bottle body baffle cylinder. 2. Set a delay, control the bottle baffle cylinder 2 and the bottle baffle cylinder 3 to release the bottle at the same time, and the photoelectric sensor 4 starts to count. When the set value is reached, the bottle baffle cylinder 3 acts to block the bottle, and at the same time The bottle feeding line changing device composed of the bottle feeding line changing baffle 7 and the bottle feeding line changing baffle 38 is controlled by the baffle swinging cylinder 5 and the baffle swinging cylinder 6 to swing, so that the bottle body is changed by the first conveyor belt A. On the second conveyor belt B, at the same time, the bottle body baffle cylinder 11 blocks the bottles, and at this time, the first conveyor belt A works again to continue to feed the bottles.
[0044] At the same time, when the photoelectric sensor 8 counts to the set value, the second conveyor belt drive motor 16 of the bottle baffle cylinder controls the second conveyor belt B to stop rotating, and the execution cylinder 27 and the execution cylinder 28 control the filling nozzle to move from the initial state to Above the second conveyor belt B, after the positioning proximity sensor 25 receives the signal, it controls the filling nozzle lifting cylinder 22 and the filling nozzle lifting cylinder 29 to descend, so that the filling nozzle 39 and the container centering positioner 35 are close to the bottle mouth and start filling. .
[0045] When the filling is completed, the filling nozzle lifting cylinder 22 and the filling nozzle lifting cylinder 29 lift the filling nozzle 39 and the container centralizer 35 to wait for line change.
[0046] Then, the bottle body baffle cylinder 11 is opened, and the second conveyor belt driving motor 16 drives the second conveyor belt B to rotate, and starts to release the bottle body filled with liquid. When the bottle output photoelectric sensor 12 counts to the set value, the bottle body baffle cylinder 11 acts to block the bottle again, and the bottle output change line baffle 15 changes the line of the filled bottle body to the first conveyor belt A to be sent out for filling. installed.
[0047] The empty bottle in front is counted by the photoelectric sensor 4 and enters synchronously, waiting for filling. The execution cylinder 27 and the execution cylinder 28 control the filling nozzle to move from the initial state to the top of the third conveyor belt C. At this time, the photoelectricity on the third conveyor belt C The sensor 9 counts to the set value, the second conveyor belt drive motor 17 controls the third conveyor belt C to stop rotating, the execution cylinder 27 and the execution cylinder 28 control the filling nozzle to move above the third conveyor belt C, and the positioning proximity sensor 24 accepts Signal to control the filling nozzle lifting cylinder 22 and the filling nozzle lifting cylinder 29 to descend, so that the filling nozzle 39 and the container centering positioner 35 are close to the bottle mouth and start filling.
[0048] When the filling nozzle 39 performs filling, the solenoid valve 34 and the pneumatic valve 23 are all opened under the control of the PLC, and the solenoid valve 34 is closed in advance a few seconds before the end of the filling to slow down the filling speed and slow down the water hammer. The purpose of two-speed filling is to prevent overflow.
[0049] When the filling is completed, the filling nozzle lifting cylinder 22 and the filling nozzle lifting cylinder 29 lift the filling nozzle 39 and the container centralizer 35 to wait for line change.
[0050] Then, the bottle body baffle cylinder 13 is opened, and the third conveyor belt driving motor 17 drives the third conveyor belt C to rotate, and starts to release the bottle body filled with liquid. When the bottle output photoelectric sensor 14 counts to the set value, the bottle body baffle cylinder 13 acts to block the bottle again, and the bottle output change line baffle 18 changes the line of the filled bottle body to the first conveyor belt A to be sent out for filling. installed.
[0051] The invention completes a fully automatic working cycle through the reciprocating action under the control of the programming controller. The invention enables the bottle body to be filled continuously by changing the line of the bottle body, which overcomes the traditional filling machine as the bottle body. When filling, it is necessary to wait for the defect of entering the bottle, which shortens the interval time between bottles and improves the filling efficiency.
