a transmission carrier 21 extending at least from the feed position 11 to the discharge position 12;
the driving assembly 22 is in driving connection with the transmission carrier 21; and
the first detection piece 31 is arranged at the front side of the discharging position 12 in an adjacent mode and is electrically connected with the driving assembly 22;
the driving component 22 is used for driving the transmission carrier 21 to transmit, and enabling the transmission carrier 21 to have a moving trend larger than the section step distance D; when the first detecting element 31 detects a preset material signal, the driving assembly 22 controls the transmission carrier 21 to slow down and stop so that the preset material stops at the discharging position 12; and the section step distance D is the distance between two adjacent preset materials.
Without loss of generality, in this embodiment, a material is placed on the transmission carrier 21 at intervals of a preset distance. When the material is removed in a manner of removing only one material from the discharge position 12 at a time (at this time, the preset material is one material), after the material on the discharge position 12 is removed, the driving assembly 22 is required to drive the transmission carrier 21 to transmit the preset distance, so that the next material can be transmitted to the discharge position 12, that is, the step distance D at this time is the preset distance. When the material group is moved away in a manner of moving away N (N is a natural number greater than 1) materials from the discharge position 12 at one time (at this time, the preset material includes a combination of N materials at intervals), after the N materials on the discharge position 12 are moved away, the driving assembly 22 is required to drive the transmission carrier 21 to transmit N preset distances, so that the next group of N materials can be transmitted to the discharge position 12, that is, the step distance D at this time is N preset distances.

Optionally, the first optical fiber detector is provided with an optical fiber detection head, and the preset material signal includes N edge-change signals detected by the optical fiber detection head; that is, when the optical fiber detection head of the first optical fiber detector detects the continuous variation signal of the light for N times, it may be determined that the preset material signal has been detected. In the embodiment, only one optical fiber detection head is needed to be arranged on the first optical fiber detector, so that the cost can be saved; however, the design is not limited thereto, and in other embodiments, the first optical fiber detector may also include N optical fiber detection heads, and at this time, when the N optical fiber detection heads simultaneously detect the material signal, it may be determined that the predetermined material signal has been detected.
