s2: when the pusher is detected to be at the preparation position, the third metal sensor detects a steel billet, the pusher pushes the steel billet to move forward, and the steel billet is pushed to reach the second hoisting position;
when the metal sensor IV detects that the steel pusher is in place, the steel pusher stops moving forward, and the steel pusher automatically resets to a preparation position;
while counter + 1;
s3: when the pusher is detected to be at the preparation position, the third metal sensor detects a steel billet, the pusher pushes the steel billet to move forward, and the steel billet is pushed to reach the first hoisting position;
when the metal sensor five detects in place, the pusher stops advancing, and when the metal sensor four and the metal sensor five detect simultaneously, the pusher stops acting to wait for hoisting;
when the counter is equal to 6, the pusher stops acting and waits for hoisting to form linkage;
the linkage conditions are specifically as follows:
when the metal sensor IV and the metal sensor V are simultaneously sensed, 6 steel billets are exactly arranged between the hoisting position II and the hoisting position I, the steel pusher is locked to be prevented from moving, and the phenomenon that one steel pusher is provided with more steel billets is prevented;
when the metal sensor IV and the metal sensor V do not sense simultaneously, the condition that the pusher does not meet the first 6 is indicated, and the linkage is not needed, so that the pusher can normally run.
S4: and when the metal sensor IV and the metal sensor V cannot detect, the recovery counter is 0, the counting is repeated, and the pusher is automatically controlled to retreat and automatically reset to a preparation position.

Please refer to fig. 1-2, which are a method for automatically controlling a pusher.
Arranging a metal sensor five X5 on a first hoisting position, arranging a metal sensor four X4 on a second hoisting position, and arranging a metal sensor three X3 on a preparation position; the first hoisting position and the second hoisting position are separated by a distance of 6 steel bars;
the square billet falls on a roller way of the steel pusher, and a second metal sensor X2 detects the square billet in place;
when the billet is detected by the metal sensor three X3, the pusher is also detected at the preparation position, and at the moment, the pusher pushes the billet to advance Y1 to push the billet to reach the second hoisting position. And stopping the steel pusher from advancing until the metal sensor four X4 detects that the steel pusher is in place, and automatically resetting the steel pusher to a preparation position at the moment. While counter C0+ 1.
When a billet is detected by the metal sensor three X3, the pusher also detects that the billet is at a preparation position, the pusher pushes the billet to advance Y1 to push the billet to reach a first hoisting position, when the metal sensor five X5 detects that the billet is in place, the pusher stops advancing, and when the metal sensor four X4 and the metal sensor five X5 detect simultaneously, the pusher stops acting to wait hoisting, and when a counter C0 is equal to 6, the pusher stops acting to wait hoisting, so that linkage is formed.
When the four X4 metal sensors and the five X5 metal sensors simultaneously sense, 6 steel billets are exactly arranged between the second hoisting position and the first hoisting position, the pusher is locked to be prevented from moving, and the phenomenon that one steel billet is supported by more steel billets is prevented;
when the four X4 metal sensors and the five X5 metal sensors do not sense simultaneously, the condition that the pusher does not meet the condition of one first 6 steel is indicated, and the pusher does not need to be interlocked, so that the pusher can normally run.
Since the counter C is equal to 1 for 1 billet and 6 for one A, the crane is waited to be hoisted after one A. When the metal sensor four X4 and the metal sensor five X5 cannot detect, the recovery counter C0 counts again at 0, and automatically controls the pusher to retreat Y2 and automatically resets to a preparation position.
