Further, I/0 interface arrangement of the present invention is made up of the first opening travel switch interface, the second opening travel switch interface, the first closing stroke switch interface, the second closing stroke switch interface, infrared sensor interface, interface of releasing the button, close push button interface, unlatching cylinder solenoid valve interface and closed cylinder solenoid valve interface; Each interface connects corresponding the first opening travel switch, the second opening travel switch, the first closing stroke switch, the second closing stroke switch, infrared sensor respectively, releases the button, close push button, unlatching cylinder solenoid valve and closed cylinder solenoid valve.
Further say, infrared sensor of the present invention is arranged between two fan safety door bodies.
The invention has the beneficial effects as follows: automatic open and close can be realized, and whether can have human body in the middle of automatic gauging safety door in closing course, close if any then not realizing, avoid safety door casualty accident, protection personal safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is safety door schematic diagram of the present invention;
Fig. 2 is I/0 interface arrangement schematic diagram of the present invention;
Fig. 3 is PLC programme diagram of the present invention;
In figure 1, opening travel switch 13 (SQ1) interface; 2, opening travel switch 14 (SQ2) interface; 3, closing stroke switch 17 (SQ3) interface; 4, closing stroke switch 18 (SQ4) interface; 5, infrared sensor (IR) interface; 6, to release the button (SB1) interface; 7, close push button (SB2) interface; 8, cylinder solenoid valve interface is opened; 9, closed cylinder solenoid valve interface; 10,11, safety door; 12, I/O interface arrangement; 13, opening travel switch (SQ1); 14, opening travel switch (SQ2); 15, infrared sensor; 16, guide rail; 17, closing stroke switch (SQ3); 18, closing stroke switch (SQ4).
Detailed description of the invention
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of Digit Control Machine Tool automatic safety door embodiment, comprise: opening travel switch 13 (SQ1) interface 1, opening travel switch 14 (SQ2) interface 2, closing stroke switch 17 (SQ3) interface 3, closing stroke switch 18 (SQ4) interface 4, infrared sensor (IR) interface 5, button (SB1) interface 6, button (SB2) interface 7, open cylinder solenoid valve interface 8, closed cylinder solenoid valve interface 9, safety door 10, safety door 11, I/O interface arrangement 12, opening travel switch (SQ1) 13, opening travel switch (SQ2) 14, infrared sensor 15, guide rail 16, folding travel switch (SQ3) 17, closing stroke switch (SQ4) 18 forms.Press and release the button 6, SB1 is 1, SQ1, SQ2, Y2 normally-closed contact is 1, opens cylinder solenoid valve interface 8 and obtains electric, namely Y1 is 1, safety door 10,11 is opened, when safety door 10,11 run simultaneously contact with opening travel switch 13 (SQ1), opening travel switch 14 (SQ2) time, SQ1 and SQ2 is 0 simultaneously, Y1 is 0, cylinder solenoid valve interface 8 dead electricity, safety door 10,11 stop motion, realizes opening completely; Press close push button 7, SB2 is 1, IR, SQ3, SQ4, Y1 normally-closed contact is 1, and closed cylinder solenoid valve interface 9 obtains electric, namely Y2 is 1, safety door 10,11 closes, when safety door 10,11 run simultaneously contact with closing stroke switch 17 (SQ3), closing stroke switch 18 (SQ4) time, SQ3 and SQ4 is 0 simultaneously, Y2 is 0, closed cylinder solenoid valve interface 9 dead electricity, safety door 10,11 stop motion, realizes completely closed; In closing course, if infrared sensor 15 is checked in the middle of safety door 11,12 human body, then IR normally-closed contact is 0, and normally opened contact is 1, Y2 is 0, can not realize closing, and avoids human body by safety door injury accident; Y1 and Y2 realizes interlocking by normally-closed contact, and namely safety door 11,12 can not be opened when closed, can not close when opening.
