Abstract
The invention relates to a roll gap pressure adjustment method of steel plate coating machine, in particular to an automatic pressure adjustment method of the coating machine coating roll and the fluid taking roll. The invention mainly solves the technical problem that the manual adjustment method can not adjust the pressure intensity of the coating roll and the fluid taking roll in real time. The technical proposal of the invention is an automatic pressure adjustment method of the coating machine coating roll and the fluid taking roll , comprising the steps as follows: storage steps: add or subtract 300 Pa to or from the pressure value SV and then feed the result value into the 2D register; comparison steps: compare the result value with the PV value measured by the pressure sensor, examine whether the PV value is within the limit; if the PV value is within the limit, the adjustments finishes; if the PV value is not within the limit, enter the signal transmission steps; the signal transmission steps: close the normal open of the time relay and send running signals or running speed signals to the servo amplifier; the adjustment steps: adjust the pressure through the servo amplifier, and the adjustment finishes after the SV value reaches the setting range. The invention mainly applies to the automatic adjustment of the pressure between the roll A and the roll P of the coating machine.
Description
Technical field:
The present invention relates to a kind of steel plate coating machine roll gap pressure method of adjustment, particularly a kind of coating machine coating roller with get liquid roller pressure Automatic adjustment method.
Background technology:
Silicon steel coating machine coating roller (A roller) and the pressure oscillation of getting between liquid roller (P roller) in process of production relies on the operative employee manually to revise all the time.Because pressure oscillation is more frequent in producing in the recent period, and undulating value is bigger, cause force value between A, P roller can't satisfy the requirement of production technology.The coating of former coating machine and the pressure of getting between the liquid roller are regulated with reference to Fig. 1, and according to coating roller and big or small given (the SV value) of getting liquid roller gap, the operative employee is according to the size of manual adjustments SV value, then by servo amplifier control servomotor.
The main drawback that original technology exists has: 1) can't adjust coating roller and the pressure size of getting the liquid roller in real time.2) increased operative employee's labour intensity greatly.3) be not inconsistent with the supermatic mentality of designing of coating machine, wasted existing equipments resources.
Summary of the invention:
The purpose of this invention is to provide a kind of coating machine coating roller and get liquid roller pressure Automatic adjustment method, mainly solve the manual setting method and can't adjust coating roller and the technical problem of getting the pressure size of liquid roller in real time.Technical scheme of the present invention is: a kind of coating machine coating roller with get liquid roller pressure Automatic adjustment method, may further comprise the steps:
Storing step will be sent into the 2D register behind the pressure SV value plus-minus 300Pa;
Comparison step compares SV value and the PV value that pressure sensor records of plus-minus 300Pa, inspection PV value whether in scope, if in scope, the adjusting end, if no longer in the scope, the entering signal forwarding step;
The signal forwarding step closes the normal switching of the time relay to servo amplifier transmission run signal and running speed signal;
Regulating step is regulated the pressure size by servo amplifier, and the setting range interior back adjusting that arrives the SV value finishes.
A kind of coating machine coating roller with get liquid roller pressure self-checking device, comprise coating roller and get the liquid roller, it is characterized in that also comprising with coating roller with get a pressure sensor and the computer that the liquid roller links to each other, described computer comprises:
Memory cell will be sent into the 2D register behind the pressure SV value plus-minus 300Pa;
Comparing unit compares SV value and the PV value that pressure sensor records of plus-minus 300Pa, and checks the PV value whether in scope, if in scope, if the adjusting end no longer in the scope, is carried out the signal transmission;
Signal transmitting unit closes the normal switching of the time relay to servo amplifier transmission run signal and running speed signal;
Regulon is regulated the pressure size by servo amplifier, and the setting range interior back adjusting that arrives the SV value finishes.
Beneficial effect of the present invention is: having solved original force value can't self-regulating drawback, and guaranteeing that motor can be with pressure size all-the-time stable in the desired scope of technology under the prerequisite of frequent movement, thereby can significantly promote product quality and improve operative employee's labour intensity.

The specific embodiment:
With reference to Fig. 2,3, a kind of coating machine coating roller with get liquid roller pressure Automatic adjustment method, may further comprise the steps:
Storing step will be sent into the 2D register behind the pressure SV value plus-minus 300Pa;
Comparison step compares SV value and the PV value that pressure sensor records of plus-minus 300Pa, inspection PV value whether in scope, if in scope, the adjusting end, if no longer in the scope, the entering signal forwarding step;
The signal forwarding step closes the normal switching of the time relay to servo amplifier transmission run signal and running speed signal;
Regulating step is regulated the pressure size by servo amplifier, and the setting range interior back adjusting that arrives the SV value finishes.
A kind of coating machine coating roller with get liquid roller pressure self-checking device, comprise coating roller and get the liquid roller, it is characterized in that also comprising with coating roller with get a pressure sensor and the computer that the liquid roller links to each other, described computer comprises:
Memory cell will be sent into the 2D register behind the pressure SV value plus-minus 300Pa;
Comparing unit compares SV value and the PV value that pressure sensor records of plus-minus 300Pa, and checks the PV value whether in scope, if in scope, if the adjusting end no longer in the scope, is carried out the signal transmission;
Signal transmitting unit closes the normal switching of the time relay to servo amplifier transmission run signal and running speed signal;
Regulon is regulated the pressure size by servo amplifier, and the setting range interior back adjusting that arrives the SV value finishes.
With reference to Fig. 4, B800 is at the newly-increased automatic pressure of panel and regulates button as shown at right, and B0D7 originally was the manual adjustments conclusion button, now with this push button function expansion, has added the end automatic regulation function.Figure below is B800 and the realization of B0D7 push button function in program.M6540 is the interlocking of manual mode.
With reference to Fig. 5, W1D6 takes from pressure sensor and send in register D1280 after 100, M4252 closure after pressing B800, numerical value among the D1280 is added, delivers to D1158 and D1160 respectively after subtracting 3, M4253 puts 1 when equating with D1280 as D1128 (PV value), this moment M4253 relay T80 normally closed some turn-off time, time relay T81 just can't export that (T80 increases pressure, T81 reduces pressure), thus the servomotor frequent movement avoided.
And only have when the PV value greater than SV value 300Pa or PV value during less than SV value 300Pa program M4253 can be set to 0 automatically, thereby so that T80 or T81 put 1.
So far, do the action of real-time relatively rear drive servomotor by the pressure P V value that pressure sensor obtains with setting value SV, formed a new closed loop.
Last T80 or T81 be afterwards action in 3 seconds regularly, and 6 as sending the servomotor responsiveness into the D5040 register take T80 as illustration.
With reference to Fig. 7, the rising edge of getting T80 is sent K200000 into D5090 makes servomotor obtain the moving target value.
With reference to Fig. 8, the adhesive of T80 coil meanwhile makes M6528 put 1, and servomotor obtains the START signal.Translational speed has been arranged, and action desired value and START signal servomotor just can be revised the pressure size of AP roller automatically.
