In the invention, a notch can be arranged on the vertical baffle 61, and when the yarn rod is required to be guided out from the lower discharging guide plate 65, the power mechanism 64 drives the lower discharging guide plate 65 to move out from the notch, so that the yarn rod can directly fall onto the lower discharging guide plate 65 and is guided out from the lower discharging guide plate 65.

In the present invention, the yarn bar for recognizing most of the yarn wound around it may have other configurations, as shown in fig. 11 to 13, the recognition unit in this embodiment includes a yarn recognition mechanism 9 for recognizing most of the yarn wound around it, the yarn recognition mechanism 9 includes a mounting seat 91, a swinging rod 92 connected to the mounting seat 91 and capable of swinging relative to the connection point, and a proximity switch 93 provided on the mounting seat 91; the two ends of the swinging rod 92 are respectively provided with a contact piece 94 which extends to the conveying unit and can be contacted with a yarn rod on the conveying unit and a sensing piece 95 which is close to the proximity switch 93. When the yarn rod is conveyed on the conveying unit and conveyed to the station of the yarn identifying mechanism 9, the yarn rod is conveyed between the contact piece 94 and the conveying unit, the conveying is stopped, the yarn rod is contacted with the contact piece 94, the swinging rod 92 can swing around the connecting position, so that the yarn rod pushes the contact piece 94 to move, the swinging rod 92 is driven to swing, and after the swinging rod 92 swings, the sensing piece 95 at the other end of the swinging rod 92 swings along with the swinging piece, so that displacement change occurs between the sensing piece 95 and the proximity switch 93. When yarns with different thicknesses are wound on the yarn rod, the displacement of the contact piece 94 is different, and the displacement change sensed by the proximity switch 93 is different, so that whether most of the yarns are wound on the yarn rod can be judged according to the displacement change sensed by the proximity switch 93.

As shown in fig. 11 and 12, the contact 94 of the present invention may have various structures, for example, the contact 94 may be a roller. The invention adopts the structural form of the roller, can reduce the friction force with the yarn of the yarn bar and avoid damaging the yarn. The yarn identifying mechanism 9 includes a stopper rod 99 provided on the mount 91 for restricting the rotation angle range of the swing lever 92. The swing lever 92 is provided with a limit groove 921 which is matched with the limit lever.

As shown in fig. 11 and 12, in order to maintain the recognition accuracy, the yarn recognizing mechanism 9 further includes a return spring 96 provided between the mount 91 and the swing lever 92. After one yarn rod is identified, the swinging rod 92 is restored to the original position under the action of the reset spring 96, so that the next yarn rod is identified conveniently. The mounting seat 91 is provided with a mounting column 97, the swing rod 92 is provided with a connecting column 98, and two ends of the return spring 96 are respectively connected to the mounting column 97 and the connecting column 98.

According to the invention, a plurality of sensors can be arranged along the conveying direction of the conveying unit, and the sensors are used for sensing the conveying positions of the yarn bars so as to be matched and connected with each station.
