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

Sizing material is located sampling control method automatically
Technical field
The invention provides a kind ofly for the rubber tyre production run, automatically locate and complete the control method of sampling for glue stuff compounding, belong 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 mixing process, need the sizing material of specifying train number is positioned sampling, censorship with the glue stuff compounding quality assessment, and expect to obtain to improve the Data support of raw material, rubber mixing technique and sizing material stability.
The sampling of current sizing material location, more is operating personnel obtain based on the empirical data of many train numbers sizing material binder removal length, and sample time is comparatively fixing, does not consider the equipment of production scene, the actual conditions of personnel's judgement.
Easily cause larger error because of sampling operation personnel's carelessness or error in judgement, or even sampling train number, the mistake of sample time, thereby lose the checking reference role of sampling censorship.
The sizing material character of different formulations, sampling craft 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 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 sampling control method automatically, no matter whether dispose the predetermined formula information database of setting up of subsidiary engine primary control program, can both be in the situation that different sampling crafts, sizing compound formula, binder removal device parameter realize location sampling operation automatically.
