Abstract
The utility model relates to an automatic frequency conversion numerical control industrial door which comprises a power switch 1 and a servo motor 4 for controlling an automatic door to open and close, wherein a rotary shaft of the motor 4 is provided with a brake gate 5 and a limit switch 8. The automatic door is controlled by a programmable controller 3. The motor 4 is connected with a speed regulation frequency changer 2, and the rotary shaft of the motor 4 is connected with a rotary encoder 6 through a coupler, wherein count values of the rotary encoder 6 are inputted into the programmable controller 3. The automatic door can also realize human sensing automatic control, and the rotary encoder is used for measuring limiting to ensure that the limiting of the automatic door is accurate. The utility model uses frequency conversion for power supply, ensures that the processes of speed reduction, braking and stop are transited smoothly, and has the advantages of low running noise and favorable sealing performance.
Description
The utility model relates to a kind of industrial door of automatic control, as rolling door, sliding door, last slide etc.
At present, the general industry door does not have speed-regulating function because control circuit is simple, and mechanical limit switch causes when cutting out sealing poor because machining accuracy is not enough, and repetitive error is bigger.Owing to be full voltage starting, starting current is big, and the motor feels hot seriously, it is big, mechanical to impact, electric noise is big, and it is also big to wear and tear, and often breaks down in use.In order to improve the precision of automatic door, generally be that control section is improved in the prior art, for example Chinese patent application CN2218243Y discloses a kind of " the programme-control servomechanism installation of automatic door ", be to cooperate five microswitches as the stage monitoring and control of sliding door orbit position automatically by a coding circuit, this apparatus structure is fairly simple, only be program coding, can not carry out digital spacing control.
The purpose of this utility model is to obtain a kind of automatic industrial door, is to adopt digital spacing control, and the startup of Frequency Converter Control motor, braking can reduce startups, braking is impacted, make its parking spot accurate, operate steadily, noise is little, good airproof performance.
For achieving the above object, the technical solution that the utility model proposes is:
A kind of frequency conversion numerical control automatic industrial door, it comprises: the servomotor 4 of power switch 1, the folding of control automatic door, damper brake 5 and limit switch 8 are arranged in the rotating shaft of motor 4, be to adopt programmable controller 3 to control, the power input of motor 4 is connected to speed governing frequency converter 2, the rotating shaft of motor 4 links to each other with rotary encoder 6 through coupler, and the count value input programmable logic controller 3 of rotary encoder 6 realizes that numeral is spacing.
Introduce an embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is depicted as the circuit theory schematic diagram of the utility model frequency conversion numerical control automatic industrial door.
Referring to accompanying drawing, 1 is that (φ 3, and 380v), three-phase alternating current is divided into two-way, and one road input converter 2 (FVR15E9S) is realized the folding of variable frequency regulating speed control automatic door through the output UVW of frequency converter 2 control servomotor 4 for power switch; Another road is through fuse 12 inputs control device 3 (FX able to programme
0-14MR) as power supply.The rotating shaft of motor 4 is coupled through coupler and rotary encoder 6 (E6A2-CW5), relevant position with the rotary encoder detecting gate, the revolution of motor 4 is imported control device 3 able to programme, carry out precise counting by the high-speed counter in the control device 3 able to programme and realize spacing Digital Control, 8 is the limit switch of motor.Control device 3 able to programme also is connected to manual changeover switch 11, realizes that the people feels automatic control, and a is for manually descending, b is for manually up, and c is work automatically, and switch 11 is felt infrared ray sensor 10 with the people and connected, can realize that the people opens the door, the people walks automatically and closes the door, and 9 is conveyor trip switch.On the axle of motor 4 damper brake 5 is arranged, control device 3 able to programme is through 5 actions of damper brake relay 7 control damper brakes.
The utility model can be realized contactless control owing to adopt programmable controller to control, and directly controls frequency converter by programmable controller; Measure the displacement digital quantity of door with rotary encoder, it is spacing to carry out numeral by the spacing setting value of control device able to programme, can not have repetitive error like this, guarantees that automatic door is spacing accurate; Variable-frequency control technique carries out the characteristic of the optimum start-up that starts/stop all by designing requirement/stop, deceleration-braking-stopped process is all seamlessly transitted, electric during parking, machinery does not all have impact phenomenon, has significantly reduced mechanical shock and noise, has prolonged the application life of equipment.The utility model can be applied in occasions such as senior commercial building, hotel, hospital, scientific research department, military project department.
