For example, if a misjudgment occurs during the previous detection, so that the complete product packaging is identified as a defective product packaging, such products are recycled and used normally through secondary detection; for the products determined to have defects, they are classified according to the severity of the defects through secondary detection. For example, the first level is reusable after repair, and the second level is to be destroyed because it cannot be repaired.

[0098] The embodiment of the present invention further provides a control method for a boxed product rejection device for a T-shaped channel, which is applied to the electrical control component of the boxed product rejection device for a T-shaped channel in the above embodiment. The method includes:

[0099] S1. Obtaining location information of defective boxed products;

[0100] S2. When the boxed product with defects is located above the first photoelectric sensor 10, the first conveying channel 101 is controlled to stop conveying;

[0101] S3, after the first conveying channel 101 stops conveying, the automatic lifting component 2 is controlled to rise, so that the automatic conveying component contacts the boxed products, and the automatic conveying component is controlled to convey the defective boxed products to the rejection channel 4.

[0102] In this embodiment, Figure 10 As shown, when the defective boxed product is delivered to the top of the first photoelectric sensor 10, the electrical control component 5 controls the first conveying channel 101 to stop conveying, controls the automatic lifting component 2 to rise, so that the automatic conveying component contacts the boxed product, and the automatic conveying component conveys the defective boxed product to the rejection channel 4. After the boxed defective product is delivered to the rejection channel 4, when the first photoelectric sensor 10 detects that there is no product at the rejection station, the drive motor 17 is controlled to stop rotating, the lifting cylinder 21 is retracted, the automatic conveying component descends, and the first conveying channel 101 is controlled to continue conveying.

[0103] In a specific embodiment, Figure 1 and Figure 11 As shown in the figure, the position of the boxed product A is the last station of the boxed product assembly line in the direction X that reaches the rejection station, and its arrival signal is input to I0.1 of the PLC by the third photoelectric sensor 9. The position of the boxed product B is the last station of the boxed product assembly line in the direction Y that reaches the rejection station, and its arrival signal is input to I0.0 of the PLC by the second photoelectric sensor 8.

[0104] When the upstream process detects that one of the boxed product A and the boxed product B is a defective product, it is assumed that the boxed product A is a defective product. When the upstream process detects that the boxed product A is a defective product, and the boxed product A arrives at the rejection station before the boxed product B, the first photoelectric sensor 10 detects that the boxed product A arrives at the rejection station, and the high-level signal is fed back to I0.2 of the PLC. The PLC outputs a low-level signal to control the boxed product assembly line direction Y to stop conveying. At the same time, the PLC sends a high-level signal Q0.0 to energize the left coil of the three-position five-way electromagnetic reversing valve, and the electromagnetic reversing valve is turned on, and the lifting cylinder 21 extends. The piston rod of the lifting cylinder 21 lifts the automatic conveying assembly as a whole through the piston rod connector 25, the piston push plate 24, and the load connecting plate 13. At the same time, the four cylinder motion guide columns 22 are pushed upward along the corresponding guide sleeves 23 to ensure the stability of the cylinder movement. At this time, the defective boxed product is lifted together with the automatic conveying assembly.

[0105] When the second magnetic induction switch 27 detects that the jacking cylinder 21 extends in place, it sends the high-level signal to I0.4 of the PLC. The PLC outputs a high-level signal Q0.2 to make the relay coil energized and conductive. The relay auxiliary contact controls the contactor to close, and the drive motor 17 starts to rotate. The drive motor 17 converts the rotational speed into the required speed through the reducer 12. The output shaft of the reducer 12 drives the driving gear 40 to rotate. Under the action of the chain 42, the power is transferred from the driving gear to the driven gear 41. The driven gear 41 transmits the power to the belt power input shaft 43 through a flat key. Since there are 3 identical driving belt pulleys 54 evenly distributed on the belt power input shaft 43, therefore, under the action of the belt 52 and the tensioning pulley 16, the power on the belt power input shaft 43 is finally transmitted to the corresponding driven belt pulley 15, and the 3 belts 52 rotate synchronously. The boxed defective product A moves along the running direction of the belt under the action of the frictional force on the belt surface, and finally transports the boxed defective product A to the rejection channel 4.

[0106] After the boxed defective product A is transported to the rejection channel 4, when the first photoelectric sensor 10 detects that there is no product at the rejection station, it sends the low-level signal to the point I0.2 of the PLC. The PLC's Q0.2 outputs a low-level signal, and this low-level signal makes the relay coil de-energized. The relay auxiliary contact controls the contactor to disconnect, and the drive motor 17 stops rotating. At the same time, the PLC point Q0.1 outputs a high-level signal to make the right coil of the three-position five-way electromagnetic directional valve energized. The electromagnetic directional valve changes its direction, and the jacking cylinder 21 retracts. When the first magnetic induction switch 26 detects that the jacking cylinder 21 retracts in place, it sends the high-level signal to the PLC point I0.3. The PLC outputs a high-level signal to control the boxed product assembly line direction Y to continue conveying. Thus, the rejection process is completely completed.

[0107] In the above embodiments of the present invention, the boxed product rejection device and control method for the T-shaped channel can realize the non-destructive rejection of boxed defective products on the T-shaped conveying channel, ensure that the outside of the boxed products is not damaged and the internal strip products are not damaged, and can effectively reduce the production cost and the labor intensity of workers.
