Abstract
The utility model relates to a production line emergency shutdown device which comprises a plurality of normally-closed relays, a plurality of normally-closed emergency shutdown switches and a PLC. Each normally-closed emergency shutdown switch is in tandem connection with a control coil of one corresponding normally-closed relay, normally-open contacts of all the normally-closed relays are respectively in electric connection with the PLC, and the PLC is used for controlling on-off of a power source of production line equipment; the normally-closed relays, the normally-closed emergency shutdown switches and the PLC are connected into a power supply circuit. The normally-closed emergency shutdown switches can be installed at different positions of a production line, thus, workers at different working positions can power off all the operating equipment in the whole production line by triggering the normally-closed emergency shutdown switches which are closest to the workers once an accident happens, and therefore more serious safety accidents caused by delay of equipment shutdowns can be avoided.
Description
Technical field
The utility model relates to the production line emergency stop device.
Background technique
At present, the running device on production line does not have emergency stop device, and one while having an accident, and often can not shut down in time and cause larger accident.
The model utility content
The purpose of this utility model is to propose a kind of production line emergency stop device, and it can solve the problem that running device on current production line does not have emergency stop device.
In order to achieve the above object, the technological scheme that the utility model adopts is as follows:
The production line emergency stop device, it comprises a plurality of normally closed relays, a plurality of normally closed emergency stop switch and a PLC controller, the control coil serial connection of each normally closed emergency stop switch and a corresponding normally closed relay, the normally opened contact of all normally closed relays is electrically connected with the PCL controller respectively, and the PLC controller is for the break-make of the power supply of production control line equipment; Normally closed relay, normally closed emergency stop switch and PLC controller all access power supply line.
Preferably, the quantity of described normally closed emergency stop switch and normally closed relay is three.
The utlity model has following beneficial effect:
Normally closed emergency stop switch can be arranged on to places different on production line; once have an accident; the workman of different operating point can be by triggering the normally closed emergency stop switch nearest from him; make all running device outages on whole production line, thereby avoided causing not in time larger security incident because of equipment downtime.
The accompanying drawing explanation
The ladder diagram of the production line emergency stop device that Fig. 1 is the utility model preferred embodiment.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further.
As shown in Figure 1, a kind of production line emergency stop device, it comprises normally closed relay KM1, normally closed relay KM2, normally closed relay KM3, normally closed emergency stop switch JA1, normally closed emergency stop switch JA2, normally closed emergency stop switch JA3 and PLC controller (figure does not draw).
Normally closed emergency stop switch JA1 is connected in series with the control coil of normally closed relay KM1.Normally closed emergency stop switch JA2 is connected in series with the control coil of normally closed relay KM2.Normally closed emergency stop switch JA3 is connected in series with the control coil of normally closed relay KM3.
The normally opened contact K3 of the normally opened contact K1 of normally closed relay KM1, the normally opened contact K2 of normally closed relay KM2, normally closed relay KM3 also is electrically connected with the PLC controller respectively.
The PLC controller is for the break-make of the power supply of production control line equipment.Normally closed relay KM1, normally closed relay KM2, normally closed relay KM3, normally closed emergency stop switch JA1, normally closed emergency stop switch JA2, normally closed emergency stop switch JA3 and PLC controller all access power supply line.Power supply line has main switch S to control break-make.
The working procedure of the present embodiment is as follows:
Main switch S closure, line conduction, the normally opened contact K3 of the normally opened contact K1 of normally closed relay KM1, the normally opened contact K2 of normally closed relay KM2, normally closed relay KM3 is all in closed state.Now, the power supply of PLC controller apparatus for production line processed is in channel status, apparatus for production line energising work.
While having an accident on production line, trigger normally closed emergency stop switch JA1, normally closed emergency stop switch JA2, any one in normally closed emergency stop switch JA3, the normally opened contact K3 of the normally opened contact K1 of corresponding normally closed relay KM1 or the normally opened contact K2 of normally closed relay KM2 or normally closed relay KM3 disconnects, now, after the state that the PLC controller detects the normally opened contact K3 of the normally opened contact K2 of the normally opened contact K1 of normally closed relay KM1 or normally closed relay KM2 or normally closed relay KM3 changes (receiving the PLC input signal), the power supply of production control line equipment is in turnoff state, the apparatus for production line power down, quit work.
For a person skilled in the art, can make other various corresponding changes and distortion according to technological scheme described above and design, and these all changes and the distortion all should belong to the protection domain of the utility model claim within.
Claims (2)
1. production line emergency stop device, it is characterized in that, comprise a plurality of normally closed relays, a plurality of normally closed emergency stop switch and a PLC controller, the control coil serial connection of each normally closed emergency stop switch and a corresponding normally closed relay, the normally opened contact of all normally closed relays is electrically connected with the PCL controller respectively, and the PLC controller is for the break-make of the power supply of production control line equipment; Normally closed relay, normally closed emergency stop switch and PLC controller all access power supply line.
2. production line emergency stop device as claimed in claim 1, is characterized in that, the quantity of described normally closed emergency stop switch and normally closed relay is three.
