[0054] The present embodiment provides an anti-clamping pre-dividing envelope feeding device, and its feeding method includes the following steps:

[0055] S1. Load the first stack of envelopes to the rightmost upper wrapping position 10. The shift fork mechanism 4 moves to the rightmost position. The rightmost fork extends from the gap between the upper wrapping grid plate 13 and pushes the envelopes to the first conveying position 11. Then, load the second stack of envelopes to the rightmost upper wrapping position 10. The shift fork of the shift fork mechanism 4 descends and returns to the rightmost position, extending from the gap between the upper wrapping grid plate 13 again. The two shift forks move synchronously to push the first and second stacks of envelopes to the second conveying position 12 and the first conveying position 11, respectively. Then, the third stack of envelopes is loaded into the upper wrapping position 10 again.

[0056] S2: Top-scan camera 2 scans the code on the upper surface of the top envelope of the first stack of envelopes located at second conveying position 12. The first stack of envelopes is then lifted by lifting mechanism 9 to below suction cup 101 of gripping mechanism 1. Suction cup 101 picks up the top envelope and places it at transition position 7. Bottom-scan camera 8 scans the code on the lower surface of the envelope.

[0057] S3, the top scanning camera 2 scans the upper surface of the top envelope of the first stack of envelopes located at the second conveying position 12 again, and the lifting mechanism 9 lifts the first stack of envelopes upward again, so that the top envelope is raised to the suction height, and then the gripping mechanism 1 moves horizontally, so that the two suction cups 101 are respectively located above the transition position 7 and the second conveying position 11, and the envelopes on the two stations are simultaneously sucked up and moved to the discharge position 5 and the transition position 7 respectively. The envelopes transferred to the transition position 7 are scanned from the bottom again. If the envelopes transferred to the discharge position 5 are qualified after two scans, they are conveyed to the subsequent sorting mechanism, otherwise they are picked out; S3 is repeated until all the envelopes in the first stack are processed;

[0058] S4, then the two forks of the fork mechanism 4 act synchronously to move the second stack of envelopes and the third stack of envelopes to the second conveying position 12 and the first conveying position 11 respectively, and then the fourth stack of envelopes is loaded again to the packing position 10;

[0059] S5. Repeat S2 to S4 until all the envelopes in the second stack are processed, thus achieving continuous package supply.

[0060] In order to facilitate automatic diversion, this embodiment further provides a movable discharge position 5. The regulating cylinder 504 provided at the bottom of the conveyor belt 501 of the discharge position 5 can make the conveyor belt 501 tilt downward toward its loading end, and a waste box 6 is docked at the bottom. When unqualified envelopes are found after scanning, the unqualified parts can be directly dumped into the waste box 6 through the dumping conveyor belt.

[0061] During the package feeding process, the envelopes at the second conveying position 12 can be limited by the blocking fork 33 of the anti-retraction mechanism 3 to prevent the envelope stack from falling over during the suction process of the suction cup.
