Abstract
本实用新型涉及生产线急停装置，其包括多个常闭继电器、多个常闭急停开关和一PLC控制器，每一个常闭急停开关与对应的一个常闭继电器的控制线圈串接，所有常闭继电器的常开触点分别与PCL控制器电性连接，PLC控制器用于控制生产线设备的电源的通断；常闭继电器、常闭急停开关和PLC控制器均接入供电线路。 可以将常闭急停开关安装在生产线上不同的地方，一旦发生事故，不同工作点的工人都能通过触发离他最近的常闭急停开关，使整条生产线上的所有运转设备断电，从而避免了因设备停机不及时而造成更大的安全事故。
The utility model relates to an emergency stop device for a production line, which includes a plurality of normally closed relays, a plurality of normally closed emergency stop switches and a PLC controller, and each normally closed emergency stop switch is connected in series with the control coil of a corresponding normally closed relay. The normally open contacts of all normally closed relays are electrically connected to the PCL controller, and the PLC controller is used to control the on-off of the power supply of the production line equipment; the normally closed relays, the normally closed emergency stop switch and the PLC controller are all connected to the power supply line. The normally closed emergency stop switch can be installed in different places on the production line. Once an accident occurs, workers at different work points can cut off the power of all operating equipment on the entire production line by triggering the normally closed emergency stop switch closest to him. Thereby avoiding the greater safety accident caused by untimely shutdown of the equipment.
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)
