Abstract
The invention relates to an automatic positioning and sampling control method for a sizing material, which is used for realizing automatic positioning of sampling equipment and accurate control on a sampling point and avoiding mistakes such as missed sampling, incorrect sampling and the like which are caused by manual operation or negligence. When a formula information database is connected, the sizing discharging length lx or the sizing discharging weight mx of a currently produced sizing material used for determining a sizing discharging length sampling point xn or a sizing discharging weight sampling point yn of each train number is searched and abstracted from the formula information database. When the formula information database is not connected, the sizing discharging length lx or the sizing discharging weight mx of the currently produced sizing material is generated according to data which are measured or input manually in advance, so that the sizing discharging length sampling point xn or the sizing discharging weight sampling point yn of each train number is further determined. When a sampling technique before cooling is adopted, the sizing discharging length sampling point xn of each train number is determined according to the sizing discharging length lx of the currently produced sizing material; and when the sampling technique after cooling is adopted, the sizing discharging sampling point yn of each train number is determined according to the sizing discharging weight mx of the currently produced sizing material.
Description
Technical field
The present invention provides a kind of rubber tyre production run that is used for, and locatees and accomplish the control method of sampling automatically to glue stuff compounding, belongs to rubber manufacturing machinery and automation control area.
Background technology
Along with constantly bringing forth new ideas of rubber tyre manufacturing technology, the sizing material mixing production of multiple formulations has obtained penetration and promotion.For improving the whole homogeneity of quality, auxiliary agent dispersiveness and sizing material in the mixing process, need the sizing material of specifying train number is positioned sampling, censorship with the glue stuff compounding quality assessment, and expectation obtains to improve the data support of raw material, rubber mixing technique and sizing material stability.
The location sampling of current sizing material, more is the empirical data acquisitions of operating personnel based on many train numbers sizing material binder removal length, sample time is comparatively fixing, does not consider the equipment of production scene, the actual conditions that personnel judge.
Cause than mistake because of sampling operation personnel's carelessness or error in judgement easily, or even take a sample train number, the mistake of sample time, thereby the checking reference role that sampling is inspected by ready samples lost.
The sizing material character of different formulations, the sampling technology all can be different; Mix under the prerequisite of producing at current polygamy side sizing material; How taking practicable automatic sampling algorithm to control sampling equipment to realize the automatism and the consistance of location sampling, is the technical barrier that present urgent need solves.
Summary of the invention
Sizing material of the present invention is located the sampling control method automatically; No matter whether dispose the predetermined prescription information database of setting up of subsidiary engine primary control program, can both under the situation of different sampling technology, sizing compound formula, binder removal device parameter, realize locating automatically sampling operation.
The objective of the invention is; Be to solve above-mentioned existing issue and realize sampling equipment automatic location, join the accurate control of sampling point; Avoid because of mistakes such as the leakage that manually-operated or carelessness cause are got, mistake is got, improve the consistance of accuracy, promptness and the sampling of many train numbers sizing material of sizing material censorship.
For realizing the foregoing invention purpose, said sizing material is located the sampling control method automatically, is the sampling of in specifying the mixing back sizing material of train number, carrying out well-distributed points.
Wherein, under the prerequisite that connects the prescription information database that is equipped with sampling sizing compound formula parameter in advance, sampling technology or cooling back sampling technology before selecting to take to cool off;
Based on sampling technology before the cooling, the per car binder removal length l of at first from the prescription information database, inquiring about this train number sizing material
