Technical field
The present invention relates to a kind of emergency stop interlock and system more particularly to a kind of emergency stop of more numerically-controlled machine tools interlocking dresses
It sets and system.
Background technology
With the modernization of industry, automation, intelligentized development, the continuous propulsion of industry 4.0, the high-volume stream in enterprise
Waterline processing operation has increasingly tended to intelligent, automation, and more numerically-controlled machine tools are linked to be one using truss robot
Unattended automatic production line has become a kind of trend.But on automatic production line, emergency stop switch is arranged each
On a single numerically-controlled machine tool, by next emergency stop switch can only one numerically-controlled machine tool of emergency stop, other numerically-controlled machine tools still be in work
Make state, this allow for the product formation before the emergency stop lathe overstock, the product cutout after emergency stop lathe, being caused for enterprise need not
The loss wanted, therefore there is an urgent need for a kind of schemes to solve the problems, such as this so that emergent stopping can interlock realization, press any lathe
Emergency stop switch realizes all fronts emergency stop of entire pipelining.
Invention content

Fig. 2 is the schematic diagram of emergency stop interlock system embodiment 2.
Specific implementation mode
The present invention will be further described in detail below in conjunction with the accompanying drawings.
Emergency stop interlock system embodiment 1
Lower mask body introduces a kind of emergency stop interlock system for numerically-controlled machine tool.
As shown in Figure 1, for three numerically-controlled machine tools and corresponding emergency stop interlock, emergency stop interlock includes：Every
Lathe is set there are one emergent stop signal generation circuit, i.e. the emergent stop signal of First numerically-controlled machine tool generates circuit by emergency stop switch SB1
Connect and to be formed with detection relay coil KA1-1, the emergent stop signal of second numerically-controlled machine tool generate circuit by emergency stop switch SB2 and
Detection relay coil KA1-2 connects to be formed, and the emergent stop signal input circuit of third platform numerically-controlled machine tool is by emergency stop switch SB1 and inspection
It surveys relay KA1-3 to connect to be formed, it is 24V power supplys that three emergent stop signals, which generate the power supply in circuit,.Three after parallel connection
It controls relay coil KA2-1, KA2-2, KA2-3 and detects one of a normally opened contact of relay KA1-1, KA1-2 often
Open contact, a normally opened contact of KA1-3 is connected on the both ends of 24V power supplys, form control interlock circuit, control interlock circuit
Power supply is 24V power supplys.The normally-closed contact of three control relays KA2-1, KA2-2, KA2-3 are connected to corresponding numerical control
On the emergent stop signal input terminal of lathe, that is, a normally-closed contact for controlling relay KA2-1 connects emergent stop signal input terminal
A normally-closed contact of I0.0-1, control relay KA2-2 meet emergent stop signal input terminal I0.0-2, control relay KA2-3
A normally-closed contact meet emergent stop signal input terminal I0.0-3, the other ends of three control relay normally closed contacts are connected on
The anode of 24V power supplys.
When assembly line works normally, each numerically-controlled machine tool normal operation, at this time emergency stop switch be in closed state, detect
Relay KA1-1, KA1-2, KA1-3 and control relay KA2-1, KA2-2, KA2-3 detect relay all in electricity condition is obtained
The normally opened contact of KA1-1, KA1-2, KA1-3 are closed, and the normally-closed contact of control relay KA2-1, KA2-2, KA2-3 disconnect, this
When each controller washout input terminal inputted without signal.It, should when any one emergency stop switch is pressed
The emergent stop signal input circuit of numerically-controlled machine tool is open, the detection relay coil dead electricity gone here and there, such as emergency stop switch SB2 quilts
It presses, then detects relay KA1-2 dead electricity, the contact to detect relay KA1-2 acts, i.e. normally opened contact KA1-2 disconnections,
Circuit where the normally opened contact disconnects, the coil losing electricity of control relay KA2-1, KA2-2, KA2-3, three control relays
Normally-closed contact KA2-1, KA2-2, KA2-3 action, closed state has been switched to from off-state, to which washout is defeated
Entering has washout input at terminal I0.0-1, I0.0-2, I0.0-3, three numerically-controlled machine tools while emergent stopping.
Emergency stop interlock system embodiment 2
Above-described embodiment 1 give emergency stop switch be normally closed switch, detect relay contact be normally opened contact when reality
Apply mode, as other embodiment can be using emergency stop switch normal open switch, detect relay contact as normally-closed contact, such as
Shown in Fig. 2, with embodiment 1 be different only in that emergency stop switch be normal open switch, detection relay KA1-1, KA1-2 used and
The contact of KA1-3 is normally-closed contact.
When assembly line works normally, each numerically-controlled machine tool normal operation, at this time emergency stop switch be off, detect
Relay KA1-1, KA1-2, KA1-3 are in power failure state, and control relay KA2-1, KA2-2, KA2-3 are in obtain electricity condition,
The normally-closed contact for detecting relay KA1-1, KA1-2, KA1-3 is closed, and the normally closed of control relay KA2-1, KA2-2, KA2-3 is touched
Point disconnects, and the washout input terminal of each controller is inputted without signal at this time.When any one emergency stop switch quilt
When pressing, the emergent stop signal input circuit of the numerically-controlled machine tool is closed, and the coil for the detection relay gone here and there obtains electric, three controls
The coil of relay all dead electricity, the normally-closed contact for detecting relay switch to off-state, three control relays by closed state
Normally-closed contact KA2-1, KA2-2, KA2-3 action of device, has switched to closed state, to washout from off-state
There are washout input, three numerically-controlled machine tools while emergent stopping at input terminal I0.0-1, I0.0-2, I0.0-3.
Above-described embodiment gives the emergency stop interlocked control mode of three numerically-controlled machine tools, as other embodiment, interlocking
The numerically-controlled machine tool of control can also be two, four, even more.
It is normally-closed contact that above-described embodiment, which gives control relay contact used, as other embodiment, institute
Control relay contact can also be normally opened contact, and control mode is identical as embodiment 1 and embodiment 2, only corresponds to
Program in controller does corresponding change.
Above-described embodiment gives emergency stop interlock and embodiment of the system on numerically-controlled machine tool assembly line, as it
His embodiment can also be used with emergency stop interlock and system in industries such as other assembly lines, such as glass grinding.
Emergency stop interlock embodiment
Emergency stop interlock is identical with the emergency stop interlock in system above embodiment, and so it will not be repeated.
The specific implementation mode of the present invention is presented above, but the present invention is not limited to described embodiment.At this
It invents under the thinking provided, to the technology hand in above-described embodiment by the way of being readily apparent that those skilled in the art
Duan Jinhang transformation, replace, modification, and play the role of with the present invention in relevant art means it is essentially identical, realize hair
Improving eyesight it is also essentially identical, the technical solution formed in this way is finely adjusted above-described embodiment to be formed, this technical solution
It still falls in protection scope of the present invention.
