Abstract
The invention mainly discloses a control method for a PLC (programmable logic controller) safe protective door of a machine; the control method is characterized by comprising the following steps: the opening limit is located at a normally close state, when a person presses an AN (anti-creeping), a current can pass though the switch (the switch is self-locked under pulse trigger), the current is conducted, a motor rotates forwards, the motor stops when reaching the position of an opening limiting switch, thereby finishing the opening; after an automatic door is remained at the limiting position for 30s automatically, then entering the closing process, the motor rotates inversely until the automatic reaches a closing limit; when closing the door, when a person presses the AN switch, the door stops closing and returns back to the opening limit, waits for 30s, and then enters the closing process; when the opening state is in need for a long time due to maintaining, the AN switch is pressed for a long time so as to transfer to be a manual state, namely the door is unlikely to close automatically after 30s, and the AN switch is pressed for a long time again when needing to close the door. The control method has the advantages of PLC control, simple structure, easy operation and reasonable process.
Description
Technical field
The invention belongs to the electromechanical integration field, specifically a kind of controlling method of PLC safety protective door of machinery.
Background technique
Machinery is as Infrastructure indispensable in the industrialized production, for the raising of industrialized production efficient provides many convenient, still since machinery in working order in, the general working environment that all can make high speed, danger brings hidden danger for the safety of workman's working environment.
Summary of the invention
Main task of the present invention is to provide a kind of controlling method of PLC safety protective door of machinery specifically a kind of in order to stop above-mentioned hidden danger, the controlling method of the PLC safety protective door of the machinery that the dangerous partial design protective door of machinery is realized.
In order to solve above technical problem, the controlling method of the PLC safety protective door of a kind of machinery of the present invention, it is characterized in that: step is as follows:
1) door open limit is in normally off, when the people is arranged by AN, has electric current to pass through (switch is that pulse triggering is to its self-locking) on the switch, and electric current is connected, the motor forward, and behind the arrival door open limit switching position, motor stops, and finishes and opens the door;
2) when automatic door after spacing position stops, automatic timing 30 seconds, power door operation enters the process of closing the door afterwards, motor reversal is until automatic door is to closing door limiting;
3), at closing time, the switch by AN is arranged, just stop to close the door and being back to door open limit, and after waiting for 30 seconds, enter again the program of closing the door;
4) if because of maintenance relation, need long-time door opening state, longly press the AN switch, namely change manual state over to, no longer automatic door-closing after 30 seconds needs at closing time, and length is pressed AN and got final product again.
The invention has the advantages that: PLC control, simple in structure, easy to operate, and program is reasonable.
Embodiment
The PLC safety protective door of machinery of the present invention is mainly in frame and is provided with track, and door travels in orbit.Be provided with the AN button at door, this button is controlled by PLC, by driven by motor during the moving up and down of door, the motor forward that moves upward moves downward motor reversal.
Below be the concrete controlling method of PLC safety protective door: 1) door open limit is in normally off, when the people is arranged by AN, has electric current to pass through (switch is that pulse triggering is to its self-locking) on the switch, electric current is connected, and the motor forward is behind the arrival door open limit switching position, motor stops, and finishes and opens the door;
2) when automatic door after spacing position stops, automatic timing 30 seconds, power door operation enters the process of closing the door afterwards, motor reversal is until automatic door is to closing door limiting;
3), at closing time, the switch by AN is arranged, just stop to close the door and being back to door open limit, and after waiting for 30 seconds, enter again the program of closing the door;
4) if because of maintenance relation, need long-time door opening state, longly press the AN switch, namely change manual state over to, no longer automatic door-closing after 30 seconds needs at closing time, and length is pressed AN and got final product again.
Claims (1)
1. the controlling method of the PLC safety protective door of a machinery, it is characterized in that: step is as follows:
1) door open limit is in normally off, when the people is arranged by AN, has electric current to pass through (switch is that pulse triggering is to its self-locking) on the switch, and electric current is connected, the motor forward, and behind the arrival door open limit switching position, motor stops, and finishes and opens the door;
2) when automatic door after spacing position stops, automatic timing 30 seconds, power door operation enters the process of closing the door afterwards, motor reversal is until automatic door is to closing door limiting;
3), at closing time, the switch by AN is arranged, just stop to close the door and being back to door open limit, and after waiting for 30 seconds, enter again the program of closing the door;
4) if because of maintenance relation, need long-time door opening state, longly press the AN switch, namely change manual state over to, no longer automatic door-closing after 30 seconds needs at closing time, and length is pressed AN and got final product again.
