In the present embodiment, the front end face of the first pressing portion 16 is located behind the front end face of the cover plate 14 and directly above the cover opening 13.

[0041] The first guide slope gradually inclines downward along the entering direction of the bottle cap, and the height at the lowest point is the same as the height of the first pressing portion 16, so as to facilitate the smooth passing of the normal cover with the opening upward through the spacing. In the present embodiment, the inner side of the lower surface of the first cover channel 1 includes a second guide portion 19 having a second guide slope and used for guiding the bottle cap to enter, and the second guide portion 19 is located in front of the cover opening 13, and the second guide slope gradually inclines upward along the entering direction of the bottle cap, so as to facilitate the smooth entering of the normal cover with the opening upward.

[0045] Specifically, when the forward cover passes, the two sides of the first upper arc openings 182 are allowed to pass; after the reverse cover enters, the reverse cover is prevented from passing.

[0046] The above cover screening device further comprises a first sensor 7 for detecting whether the first arc segment 18 is stuck with the cover, and a first cover ejecting member 8 telescopically arranged in the first arc segment 18 along the arrangement direction of the pair of first side arc openings 183. In the embodiment, the first sensor 7 is arranged above the first arc surface 181 and is used for detecting whether the bottle caps are accumulated, when the bottle caps are accumulated, the first cover ejecting member 8 enters the first arc segment 18 through one side of the first side arc opening 183 and ejects the reverse cover in the first arc segment 18 from the other side of the first side arc opening 183, this structure can eject the reverse cover which is mistakenly entered.

[0047] Referring to Figure 2 As shown, in the embodiment, the second cover path 2 comprises a second arc segment 24, a horizontal U-shaped segment and a second cover exiting straight segment connected in sequence, the second arc segment 24 is located between the cover screening opening 13 and the second cover exiting opening 22 and is downwardly arc protruded, one end of the second arc segment 24 is higher than the other end.

[0048] Due to the downward protrusion of the second arc segment 24, the reverse cover entering from the cover screening opening 13 is turned to the forward cover with the opening inclined upward under the action of the curve. Specifically, when the forward cover passes, the two sides of the second upper arc openings 242 are allowed to pass; after the reverse cover enters, the reverse cover is prevented from passing.

[0049] The cap sorting device further comprises a second sensor 9 for detecting whether the second arc segment 24 is blocked by caps, and a second cap ejecting member 10 telescopically arranged in the second arc segment 24 along the arrangement direction of the pair of second side arc openings 243. In the embodiment, the second sensor 9 is arranged above the second arc surface 241 for detecting whether the caps are stacked, and when the caps are stacked, the second cap ejecting member 10 enters the second arc segment 24 through one of the second side arc openings 243 and ejects the inverted caps in the second arc segment 24 through the other second side arc opening 243, so that the caps mistakenly entered (inverted caps) can be ejected.

[0050] In cooperation with the U-shaped segment and the second cap outlet linear segment, the cap outlet direction of the second cap channel 2 is the same as that of the first cap channel 1, and the second cap outlet 22 and the first cap outlet 12 are aligned along the cap outlet direction.

[0051] In another embodiment, the cap sorting device further comprises a first cap flipping member (not shown) communicating with the first cap outlet 12 and a second cap flipping member (not shown) communicating with the second cap outlet 22, which are respectively used for flipping the forward caps into inverted caps to facilitate the subsequent mechanism requiring only inverted caps.

[0053] The forward caps with the opening upward and the inverted caps with the opening downward are sequentially fed into the first cap channel 1 through the first cap inlet 11, and when passing through the cap screening opening 13:

[0054] The forward caps directly pass through and enter the first arc segment 18 downward, and then are output through the first cap outlet 12;

[0055] The inverted caps are flipped downward and enter the second arc segment 24, and are output through the second cap outlet 22 after being flipped to have the opening upward.

[0056] When the first sensor 7 detects that the caps are stacked, the first cap ejecting member 8 enters the first arc segment 18 through one of the first side arc openings 183 and ejects the inverted caps in the first arc segment 18 through the other first side arc opening 183;

[0057] When the second sensor 9 detects that the caps are stacked, the second cap ejecting member 10 enters the second arc segment 24 through one of the second side arc openings 243 and ejects the inverted caps in the second arc segment 24 through the other second side arc opening 243.
