Description
Technical Field
The invention belongs to the field of metallurgical industry, and relates to an automatic control method of a pusher.
Background
A local/remote selection switch and an extension/retraction selection switch are arranged on the cooling bed and the operation box of the steel pushing and separating machine.
The manual mode uses the push-out and retract buttons to control the action of the pusher.
In an automatic mode, when a proximity switch on a front end beam of a casting blank collecting rack detects a casting blank, a steel pusher automatically pushes the casting blank out to a hoisting position. In actual production operation, equipment automation control is disabled often because of signal detection of a detection switch is inflexible, a manual operation problem or a program problem, and a manual mode is often used.

The PLC is used for controlling the PLC to release people from heavy and tedious physical labor in a simpler mode, so that the PLC is not easily influenced by emotion and technical level of people, and process operation is stably performed. The automation is realized, the performance is stable, and a larger space is provided for the production and development of enterprises.
In order to achieve the above purpose, the present invention provides the following technical solutions:
an automatic control method of a pusher, comprising the steps of:
s1: arranging a metal sensor five on a hoisting position one, arranging a metal sensor four on a hoisting position two, and arranging a metal sensor three on a preparation position; a distance of 6 pieces of steel is arranged between the first hoisting position and the second hoisting position;
the square billet falls on a roller way of the pusher, and the second metal sensor detects the square billet in place;
s2: when the pusher is detected to be in the preparation position, the metal sensor III detects the steel billet, and the pusher pushes the steel billet to advance to push the steel billet to reach the lifting position II;
stopping the advance of the pusher until the metal sensor IV detects the position, and automatically resetting the pusher to the preparation position;
a simultaneous counter +1;
s3: when the pusher is detected to be in the preparation position, the metal sensor III detects the steel billet, and the pusher pushes the steel billet to advance to push the steel billet to reach the first hoisting position;
when the metal sensor five detects the position, the pusher stops advancing, and when the metal sensor four and the metal sensor five detect the position at the same time, the pusher stops acting and waits for hoisting;
when the counter is equal to 6, stopping the action of the pusher, waiting for hoisting, and forming a chain;
the linkage conditions are specifically as follows:
when the metal sensor IV and the metal sensor V sense at the same time, the fact that 6 billets are exactly arranged between the second hoisting position and the first hoisting position is indicated, the pusher is locked to prohibit movement, and the phenomenon of multiple first billets is prevented;
when the metal sensor IV and the metal sensor V do not sense at the same time, the steel pusher is not required to be interlocked without meeting the condition of A6, so that the steel pusher can normally operate.
S4: and when the metal sensor IV and the metal sensor V cannot detect, the recovery counter is 0, the steel pusher is automatically controlled to retreat and automatically reset to the preparation position.
A computer device comprising a memory, a processor and a computer program stored on the memory and capable of running on the processor, the processor implementing the method of claim 1 when executing the computer program.
A computer readable storage medium having stored thereon a computer program which, when executed by a processor, implements the method of claim 1.

Please refer to fig. 1-2, which is an automatic control method of 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; a distance of 6 pieces of steel is arranged between the first hoisting position and the second hoisting position;
the square billet falls on a roller way of a pusher, and a metal sensor II X2 detects the square billet in place;
when the metal sensor three X3 detects the steel billet, the pusher also detects the preparation position, and at the moment, the pusher pushes the steel billet to advance by Y1 and pushes the steel billet to reach the second hoisting position. And stopping the pushing machine from advancing until the metal sensor four X4 detects the position, and automatically resetting the pushing machine to the preparation position at the moment. While counter c0+1.
When the metal sensor three X3 detects a billet, the pusher also detects that the preparation position is adopted, the pusher pushes the billet to advance by Y1, the billet is pushed to reach the lifting position I, when the metal sensor five X5 detects that the pusher stops advancing, and when the metal sensor four X4 and the metal sensor five X5 simultaneously detect, the pusher stops acting and waits for lifting, and when the counter C0=6, the pusher stops acting and waits for lifting, so that linkage is formed.
When the metal sensor IV X4 and the metal sensor V X5 sense at the same time, the fact that 6 billets are exactly arranged between the second hoisting position and the first hoisting position is indicated, the steel pusher is locked to prohibit movement, and the phenomenon of multiple first billets is prevented;
when the metal sensor four X4 and the metal sensor five X5 do not sense at the same time, the steel pusher is free from interlocking when the steel pusher does not meet the condition of first 6, so that the steel pusher can normally operate.
Because the counter C is equal to 1 and represents 1 billet, 6 billets are equal to one first, and one first waits for the crane to hang away. When the metal sensor four X4 and the metal sensor five X5 cannot detect, the recovery counter C0 is 0 for recounting, and the pusher is automatically controlled to retreat Y2 to be automatically reset to the preparation position.
