Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
Suddenly stop interlocking system embodiment 1
Lower mask body is introduced a kind of urgency for numerically-controlled machine and is stopped interlocking system.
As shown in Figure 1, interlocking device is stopped for three number of units controlled machines and corresponding urgency, suddenly stop interlocking device to comprise: every platform lathe is provided with an emergent stop signal and produces loop, namely connected by emergency stop switch SB1 and detection relay coil KA1-1 and formed in the emergent stop signal generation loop of First numerically-controlled machine, the emergent stop signal of the second number of units controlled machine produces loop and is formed by emergency stop switch SB2 and detection relay coil KA1-2 series connection, the emergent stop signal input circuit of the 3rd number of units controlled machine is connected by emergency stop switch SB1 and detection relay K A1-3 and is formed, the power supply in three emergent stop signal generation loops is 24V power supply.Three pilot relay coil KA2-1, KA2-2, KA2-3 after parallel connection and a normally opened contact of detection relay K A1-1, a normally opened contact of KA1-2, a normally opened contact of KA1-3 are connected on the two ends of 24V power supply, formation control interlock circuit, the power supply controlling interlock circuit is 24V power supply.The normally closed contact of three pilot relays KA2-1, KA2-2, KA2-3 is connected on the emergent stop signal input terminal of respective counts controlled machine, namely a normally closed contact of pilot relay KA2-1 meets emergent stop signal input terminal I0.0-1, a normally closed contact of pilot relay KA2-2 meets emergent stop signal input terminal I0.0-2, a normally closed contact of pilot relay KA2-3 meets emergent stop signal input terminal I0.0-3, and the other end of three pilot relay normally closed contacts is all connected on the positive pole of 24V power supply.
When streamline normally works, each number of units controlled machine normally runs, now emergency stop switch is in closure state, detect relay K A1-1, KA1-2, KA1-3 and pilot relay KA2-1, KA2-2, KA2-3 and be all in obtain electricity condition, the normally opened contact of detection relay K A1-1, KA1-2, KA1-3 closes, the normally closed contact of pilot relay KA2-1, KA2-2, KA2-3 disconnects, and now the washout input terminal of each controller does not all have signal to input.When any one emergency stop switch is pressed, the emergent stop signal input circuit of this numerically-controlled machine is open, its detection relay coil dead electricity of going here and there, such as emergency stop switch SB2 is pressed, then detect relay K A1-2 dead electricity, thus detect the contact action of relay K A1-2, namely normally opened contact KA1-2 disconnects, the loop at this normally opened contact place disconnects, pilot relay KA2-1, KA2-2, the coil losing electricity of KA2-3, the normally closed contact KA2-1 of three pilot relays, KA2-2, KA2-3 action, closure state has been switched to from off-state, thus washout input terminal I0.0-1, I0.0-2, I0.0-3 place all has washout to input, three number of units controlled machines are emergent stopping simultaneously.
Suddenly stop interlocking system embodiment 2
Embodiment when above-described embodiment 1 gives that emergency stop switch is normally closed switch, to detect the contact of relay be normally opened contact, as other embodiments can also emergency stop switch be normal open switch, to detect the contact of relay be normally closed contact, as shown in Figure 2, only be that emergency stop switch is normal open switch from the different of embodiment 1, the contact of detection relay K A1-1 used, KA1-2 and KA1-3 is normally closed contact.
When streamline normally works, each number of units controlled machine normally runs, now emergency stop switch is in off-state, detection relay K A1-1, KA1-2, KA1-3 are in power failure state, pilot relay KA2-1, KA2-2, KA2-3 are in obtain electricity condition, the normally closed contact of detection relay K A1-1, KA1-2, KA1-3 closes, and the normally closed contact of pilot relay KA2-1, KA2-2, KA2-3 disconnects, and now the washout input terminal of each controller does not all have signal to input.When any one emergency stop switch is pressed, the emergent stop signal input circuit of this numerically-controlled machine closes, the coil of its detection relay of going here and there obtains coil all dead electricity that are electric, three pilot relays, the normally closed contact detecting relay switches to off-state by closure state, normally closed contact KA2-1, KA2-2, KA2-3 action of three pilot relays, closure state has been switched to from off-state, thus washout input terminal I0.0-1, I0.0-2, I0.0-3 place all has washout to input, three number of units controlled machines are emergent stopping simultaneously.
The urgency that above-described embodiment gives three number of units controlled machines stops interlocked control mode, and as other embodiments, the numerically-controlled machine of interlocked control can also be two, four, even more.
Above-described embodiment gives pilot relay contact used and is normally closed contact, as other embodiments, pilot relay contact used can also be normally opened contact, and its control mode is identical with embodiment 2 with embodiment 1, and the program just in corresponding controller does corresponding change.
Above-described embodiment gives and anxious stops interlocking device and the embodiment of system on numerically-controlled machine streamline, as other embodiments, urgency can also stop interlocking device and the industry such as system can also be used in other streamlines, such as glass grinding.
Suddenly stop interlocking device embodiment
Suddenly stopping interlocking device and the urgency in above system embodiment, to stop interlocking device identical, therefore repeat no more.
Be presented above the specific embodiment of the present invention, but the present invention is not limited to described embodiment.Under the thinking that the present invention provides; the mode easily expected to those skilled in the art is adopted to convert the technological means in above-described embodiment, replace, revise; and the effect played goal of the invention that is substantially identical with the relevant art means in the present invention, that realize is also substantially identical; the technical scheme of such formation is carried out fine setting to above-described embodiment and is formed, and this technical scheme still falls within the scope of protection of the present invention.
