In the embodiment shown in the figure, it is a wireless detector, which transmits a wireless detection signal to the cigarette pack passing below through the hollow channel, and then detects the cigarette pack.

[0031] The cigarette pack conveying channel of the present embodiment is formed by setting a frame-shaped cover plate above the conveying device for conveying the cigarette pack 100 to limit the upward movement of the cigarette pack 100, and setting a plurality of spaced connecting plates 13 and strip baffles to form the frame-shaped cover plate. The formed hollow channel can facilitate the detection of the cigarette pack 100 by the cigarette pack detector 21, and at the same time can make the cigarette pack conveying channel convey the cigarette pack 100 more stable and reliable.

[0032] In some embodiments, as shown in the figure, the distance between the first strip baffle 11 and the second strip baffle 12 is less than the length of the cigarette pack 100 conveyed by the conveying device. This embodiment can effectively limit the upward jump of the cigarette pack. In some embodiments not shown in the figure, the distance between the first strip baffle 11 and the second strip baffle 12 is greater than the length of the cigarette pack 100 conveyed by the conveying device, but the distance between adjacent connecting plates is less than the width of the cigarette pack 100 conveyed by the conveying device.

[0033] In some embodiments, the second strip baffle 12 is hinged to the frame. In this embodiment, the frame-shaped cover can be opened or closed by rotating the second strip baffle 12 relative to the frame. In the open state, the cigarette pack can be manually taken out from above, and in the closed state, the frame-shaped cover can limit the upward jumping of the cigarette pack.

[0034] In some embodiments, as shown in the figure, the frame includes a first baffle 31 and a second baffle 32 respectively arranged on both sides of the conveying device and arranged opposite to each other. The first baffle 31 and the second baffle 32 are used to limit the movement of the cigarette package 100 from both sides of the cigarette package 100 when the conveying device conveys the cigarette package 100, and the second strip baffle 12 is hinged to the second baffle 32.

The second strip baffle 12 is hinged to the second baffle 32 by fixing a connecting block 42 on the connecting plate, and a connecting seat 41 is provided on the strip baffle where the first baffle 31 is located. The second strip baffle 12 is hinged to the second baffle 32 by hingedly connecting the connecting block 42 and the connecting seat 41.

[0035] In some embodiments, the cigarette pack conveying channel further includes an open holding device, which is used to hold the frame-shaped cover in an open position when the frame-shaped cover is rotated to an open position relative to the frame. In the embodiment shown in the figure, the axis of the hinge between the second strip baffle 12 and the second baffle wall 32 is along the conveying direction, and when the second strip baffle 12 is rotated to an open position relative to the second baffle wall 32, the open holding device is connected to the frame-shaped cover to hold the frame-shaped cover in this position. The open holding device can be set as a connecting member near the position, such as a hook member. In some embodiments, the open holding device includes a first magnetic member provided on the frame and a second magnetic member 51 provided above the frame-shaped cover, and when the frame-shaped cover is rotated to the open position, the first magnetic member and the second magnetic member 51 are attached by magnetic force.

When the frame-shaped cover is rotated to the open position, the second magnetic member 51 just contacts the first magnetic member from below, and the first magnetic member and the second magnetic member 51 are attached by magnetic force, and the magnetic force keeps the frame-shaped cover in the open position. When the magnetic force is overcome manually or by other means, the first magnetic member and the second magnetic member 51 can be separated, so that the frame-shaped cover is rotated to a closed position that limits the cigarette pack from jumping upward. In some embodiments, one of the first magnetic member and the second magnetic member 51 can also be a magnetic member, and the other is a non-magnetic metal member that can attract each other with the magnetic member.

[0036] In some embodiments, as shown in the figure, the cigarette packet conveying channel also includes a handle 14 fixedly connected to the frame-shaped cover plate, and the handle 14 is used for manual operation to rotate the frame-shaped cover plate relative to the frame.

[0037] In some embodiments, the cigarette pack detector 21 includes a photoelectric sensor. The cigarette pack detector is used to detect whether the cigarette packs on the conveying device maintain a suitable distance. For example, the cigarette pack detector 21 sends a photoelectric signal, and the photoelectric signal is blocked when the cigarette pack passes by. By detecting the blocking time and the conveying speed of the conveying device, the distance between adjacent cigarette packs can be determined.

[0038] In some embodiments, the cigarette pack detection device includes an L-shaped plate 22 fixedly connected to a connecting plate 13, and the cigarette pack detector 21 is fixedly connected to the L-shaped plate 22. The cigarette pack detector 21 is mounted on the connecting plate 13 via the L-shaped plate 22.
