Description
Technical field
This utility model relates to a kind of Delayed power failure device, a kind of Delayed power failure device being applicable to electronic materials-taking machine,
Belong to technical field of engineering machinery.
Background technology
Electronic materials-taking machine is widely used in the places such as steel scrap factory, steel mill, harbour, have use alternating current, environmental protection,
The features such as work efficiency is high, maintenance cost is low.But currently used electronic materials-taking machine is complete in work, human pilot closes machine
After device, complete machine power-off, controller data is not the most disposed and stores sometimes, and this just brings much inconvenience to work.
Summary of the invention
The purpose of this utility model is to provide a kind of Delayed power failure device being applicable to electronic materials-taking machine, and this device is at machine shutdown
Rear power supply relay can continue to work a period of time, processes and storage for controller data, work light time-delay closing, main
Motor closed mode confirmations etc., it is many convenient to bring to work.
For achieving the above object, the technical solution adopted in the utility model is: a kind of delay cut-off being applicable to electronic materials-taking machine
Device；Including key switch, diode, power supply relay, controller, the B end of the key switch in described circuit passes through
Electric fuse connects accumulator, and the ACC end of key switch connects one end of diode, and the BR end of key switch connects the DI of controller
End；The other end of described diode connects 86 ends and the DO end of controller of power supply relay；Described power supply relay
30 ends by electric fuse connect accumulator, 85 end ground connection of power supply relay；The 24V end of described controller is by insurance
Silk is connected with 87 ends of power supply relay, the GND end ground connection of controller.
The beneficial effects of the utility model are: described in be applicable to the Delayed power failure device of electronic materials-taking machine, can be to power cut-off
Device does delay cut-off control so that after shutdown, power supply relay can continue to work a period of time so that controller can process
With storage data, work light time-delay closing, mair motor is closed, is used this device convenient, flexible, safe and reliable.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model；
In figure: 1. key switch, 2. diode, 3. power supply relay, 4. controller.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As it is shown in figure 1, a kind of Delayed power failure device being applicable to electronic materials-taking machine, including key switch 1, diode 2, electricity
Source relay 3, controller 4, the B end of the key switch 1 in described circuit connects accumulator, key switch 1 through electric fuse
ACC end connect one end of diode 2, the BR end of key switch 1 connects the DI end of controller 4；Key switch is placed in OFF
During shelves, ACC end, BR end are not turned on B end；When key switch 1 is placed in ON shelves, ACC end, BR end turn on B end.
The other end of described diode 2 connects 86 ends and the DO end of controller 4 of power supply relay 3；Diode 2 is
One-way conduction, electric current can only flow to 86 ends of power supply current collector 3 from the ACC end of key switch 1.
When 86 ends of described power supply relay 3 are energized, the solenoid between power supply relay 86 end and 85 ends will produce
Magnetic force, by the contact adhesive between 30 ends and 87 ends of power supply relay 3 so that 30 ends of power supply relay 3 and 87
End conducting, 30 ends of described power supply relay 3 connect accumulator, 85 end ground connection of power supply relay 3 by electric fuse.
The DI end of described controller 4 can detect whether key switch 1 is placed in ON shelves, and the DO end of controller 4 can export
24V electricity.The 24V end of described controller 4 is connected with 87 ends of power supply relay 3 by electric fuse, the GND of controller 4
End ground connection.
When electronic materials-taking machine is started shooting, key switch 1 rotates to ON shelves, and+24V the unidirectional current of accumulator is driven by diode 2
Dynamic power supply relay 3 works；After power supply relay 3 work, controller 4 energising is started working；The DI end inspection of controller 4
Measuring the signal that key switch 1 is opened, the DO end of controller 4 output+24V unidirectional current, such power supply relay 3 is by key
Switch 1 and controller 4 drive jointly, and car load enters "on" position.
During the shutdown of electronic materials-taking machine, key switch 1 rotates to OFF shelves, and driving power supply relay 3 cancelled by key switch 1
Dynamic, due to the unidirectional general character of diode 2 ,+24V the unidirectional current of controller DO end does not turns on DI end, so this
Time controller 4 DI end the signal that key switch 1 is closed detected, controller 4 can calculate needs according to actual needs and prolong
Time the concrete time, delay time stops driving to power supply relay 3 to rear by DO end, and power supply relay 3 stops work
Make, car load all electrical equipments power-off.
