Then the PLC controller controls the cache cylinder 32 of the first conveying unit 18 to move, so that its piston squeezes the wedge block 31, so that the quantitative egg particles in the corresponding cache perforation 17 fall into the first egg particle chamber of the No. 1 tray 6, and the synchronous action makes the quantitative egg particles in the corresponding cache perforation 17 of the second conveying unit 19 fall into the third egg particle chamber of the No. 1 tray 6; the unloading process is relatively fast, and the unloading is completed at an interval set time (such as 200 milliseconds-300 milliseconds), and the respective cache cylinders 32 are controlled to move at any time, so that the piston is retracted to enable the blocking plate 30 to block the corresponding cache perforation 17; the interval set time After a certain time, the PLC controller controls the first motor 2 to drive the conveyor belt 1 to continue rotating, and gives a signal to control the No. 1 cylinder 26 to operate, so that it drives the No. 1 block to retract so as not to block the No. 1 tray 6, and the No. 1 tray 6 continues to be transported until the No. 2 sensor detects the No. 1 tray 6, which is at the position of the No. 2 tray 7 (which can be called the No. 2 tray 7), and then gives a signal to operate the No. 2 cylinder 27, so that its piston extends out to block the No. 2 tray 7, and the conveyor belt 1 continues to rotate at this time, and waits for the new tray to be transported to the position of the No. 1 tray 6, and then gives a signal to stop the conveyor belt 1 from rotating. At this time, the corresponding conveying units corresponding to the No. 2 tray 7 and the No. 1 tray 6 respectively operate to transport a certain amount of eggs to the corresponding egg chamber 4; the unloading process is relatively fast, and the unloading is completed at an interval set time (such as 200 milliseconds-300 milliseconds), and the respective cache cylinders 32 are controlled to operate at any time, so that the pistons are retracted to enable the blocking plate 30 to block the corresponding cache perforations 17;After the set time interval, the PLC controller controls the first motor 2 to drive the conveyor belt 1 to continue rotating, and gives a signal to retract the pistons of the No. 1 cylinder 26 and the No. 2 cylinder 27, and the No. 1 pallet 6 and the No. 2 pallet 7 continue to be conveyed until the No. 3 sensor detects the No. 2 pallet 7, which is in the position of the No. 3 pallet 8 (can be called the No. 3 pallet 8), and then gives a signal to activate the No. 3 cylinder 28, so that its piston extends out to resist the No. 3 pallet 8. At the same time, until the No. 2 sensor detects the No. 1 pallet 6, which is in the position of the No. 2 pallet 7 (can be called the No. 2 pallet 7), and then gives a signal to activate the No. 2 cylinder 27, so that its piston extends out to resist the No. 2 pallet 7. The conveyor belt 1 continues to rotate, and when the new tray is transported to the position of tray No. 1 6, a signal is given to stop the conveyor belt 1, and then the No. 1 cylinder 26 is actuated to extend its piston to resist the No. 1 tray 6, and the corresponding conveying units of tray No. 3 8, tray No. 2 7 and tray No. 1 6 are actuated respectively to convey a certain amount of eggs to the corresponding egg chamber 4, and the unloading is completed after a set time interval (such as 200 milliseconds to 300 milliseconds), and the respective cache cylinders 32 are controlled to act at any time to retract their pistons so that the blocking plate 30 can block the corresponding cache perforations 17; after the set time interval, the PLC controller controls the first motor 2 to drive the conveyor belt 1 to continue rotating. In this cycle, the synchronous delivery of eggs to the three trays is completed. ;

[0083] In the above actions, each conveying unit performs the following synchronous actions:

[0084] As mentioned above, the quantitative egg particles in a certain cache perforation 17 are transported to the egg particle chamber 4, and then a signal is given to make the second motor rotate ninety degrees. At this time, the cache perforation 17 is facing the feed pipe 12. At this time, the PLC controller controls the solenoid valve to open, and a number of egg particles in the egg particle containing body 9 fall into the storage body 11, and the storage body 11 transports the quantitative egg particles to the corresponding cache perforation 17 through the feed pipe 12 connected thereto. The quantitative egg particles are counted by the counter 14. After the counter 14 counts the quantitative egg particles, a signal is given to close the solenoid valve, and the electromagnet switch 10 is controlled to move, so that the storage body 11 corresponds to the delay tube 13, so that a number of egg particles that exceed the quantitative egg particles due to the signal transmission delay are transported to the egg particle collection body 15, and the egg particles can be used again. The second motor rotates 90 degrees so that the buffer perforations 17 with a certain amount of egg stored inside can face the funnel 33 below it, and the buffer perforations 17 without egg inside can face the feeding tube 12 above it. This arrangement can realize uninterrupted delivery of a certain amount of egg.
