Abstract
The invention relates to an online detection method of the length of a foil roll, belonging to the technical field of online detection of the length of foil rolls. The online detection method comprises the following steps of: installing a pulse signal switch before the process of reeling each roll of foils, wherein the pulse signal switch can be used for detecting the rotating cycle number of a foil driving roller and transmitting pulse signals to a programmable controller; measuring the actual diameter of the foil driving roller and inputting the numerical value into the programmable controller; and in the reeling process of each roll of foils, accumulating the pulse signals transmitted from the pulse signal switch through the programmable controller so as to obtain the rotating cycle number of the foil driving roller. The online detection method is convenient to use, has the meter-based detection precision up to micron grade by regulating the influence on the meter-based detection precision from the velocity deviation between a driving roller system and a strip material as well as the micro deviation of the driving roller diameter and can be used for carrying out precise regulation according to the wearing capacity of hardware at all times, thereby greatly improving the length detection precision of the foil roll. The invention enables the control precision to reach +/-0.001 percent; therefore, the deviation of a roll of 3000-meter foils is only 0.03 meter.
Description
Technical field
The present invention relates to length of foil roll online measuring technique field, is a kind of online detection method of length of foil roll.
Background technology
At present foil rice online detection method of length best control precision for ± 0.5%. main flow detection technique scheme is: in live roll system rotary encoder is installed, rotary encoder feeds counting machine with the signal that gathers, and it is long to calculate rice again.But there is following defective in it: 1, rotary encoder itself exists ± 0.3% detection error; 2, all exist between domestic control convenience live roll system and the band ± linear velocity deviation more than 0.2%; 3, be subjected to the restriction of hardware manufacture craft tolerance limit, there are the deviation ± 0.1% or more in live roll footpath actual value and ideal value, and live roll is long-term uses the wearing and tearing that have trace, thereby affect a meter long accuracy of detection, have irreducibility.When control accuracy was ± 0.5%, the foil deviation that a volume is 3000 meters had just reached 15 meters.
Summary of the invention
The invention provides a kind of online detection method of length of foil roll, overcome the deficiency of above-mentioned prior art, it can effectively solve the length of foil roll degree and detect the low problem of control accuracy.
Technical scheme of the present invention realizes by following measures: a kind of online detection method of length of foil roll, before every roll-leaf material coiling process, the impulse singla switch that can detect foil live roll revolution number is installed first, and this impulse singla switch is passed to Programmable Logic Controller with impulse singla; Measure the actual diameter of foil live roll and numerical value is inputed in the programmable controller program; In every roll-leaf material coiling process, the impulse singla that is transmitted by Programmable Logic Controller pulse signals switch adds up and obtains the rotation week number of foil live roll; Behind every roll-leaf material coiling process, through calculating the perimeter of foil live roll, the rotation week number of the perimeter of foil live roll and foil live roll multiplied each other namely obtains the first actual length that foil is rolled up by the actual diameter of foil live roll.
The below is the further optimization and/or improvements to the foregoing invention technical scheme:
Detect respectively the linear velocity of high regime foil volume and the linear velocity of live roll system by the high precision speed-measuring instrument, when the linear velocity that when the linear velocity of high regime foil volume and live roll is is inconsistent, calculate both linear differentials and the ratio between the high regime foil spiral speed, the first length addition with the foil volume after again the first length of the ratio that obtains and foil volume being multiplied each other namely obtains the second actual length that foil is rolled up.
The present invention is easy to use, by the impact of the micro-deviation of the velocity deviation between adjustment live roll system and the band and live roll footpath on the long accuracy of detection of rice, the long accuracy of detection of rice can reach micron order, and can carry out accurate adjustment according to the abrasion loss of hardware at any time, therefore greatly improved length of foil roll degree accuracy of detection.By the present invention make control accuracy reached ± 0.001%, the foil deviation that such volume is 3000 meters only has 0.03 meter.
The specific embodiment
The present invention is not subjected to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual conditions.
The invention will be further described below in conjunction with embodiment:
This online detection method of length of foil roll is before every roll-leaf material coiling process, and the impulse singla switch that can detect aluminium foil live roll revolution number is installed first, and this impulse singla switch is passed to Programmable Logic Controller with impulse singla; Measure the actual diameter of foil live roll and numerical value is inputed to Programmable Logic Controller; In every roll-leaf material coiling process, the impulse singla that is transmitted by Programmable Logic Controller pulse signals switch adds up and obtains the rotation week number n of foil live roll; Behind every roll-leaf material coiling process, calculated the perimeter D of foil live roll by the actual diameter C process of foil live roll, the rotation week number n of the perimeter D of foil live roll and foil live roll multiplied each other namely obtains the first actual length L1 of foil volume, i.e. D=C * π, L1=D * n.
Can according to actual needs, above-mentioned online detection method of length of foil roll be made further optimization and/or improvements:
Detect respectively the linear velocity H of high regime foil volume and the linear velocity I of live roll system by the high precision speed-measuring instrument, when the linear velocity I that when the linear velocity H of high regime foil volume and live roll is is inconsistent, calculate both linear differentials and the ratios delta V between the high regime foil spiral speed, the first length L 1 addition with the foil volume after again the first length L 1 of the ratios delta V that obtains and foil volume being multiplied each other namely obtains the second actual length L2 that foil is rolled up, i.e. L2=L1+ (L1 * Δ V).
The foil deviation that present foil rice online detection method of length best control precision is 3000 meters of ± 0.5%, one volumes has just reached 15 meters.
The present invention is through actual test: make control accuracy reached ± 0.001%, the foil deviation that such volume is 3000 meters has just reached 0.03 meter.
Above technical characterictic has consisted of most preferred embodiment of the present invention, and it has stronger comformability and best implementation result, can increase and decrease according to actual needs non-essential technical characterictic, satisfies the demand of different situations.
