摘要：The object of research is methods for analyzing the geometric parameters of textile packages formatted on machines with separate processes of yarn formation and winding. One of the most problematic places for analyzing the deviation of the shape of packages from the required is a large amount of information about the coordinates of the points of the surface of the package obtained as a result of measurements. Elimination of this problem is possible due to the creation of a volumetric packing model that allows to visually assess the presence of defects on the package surface and carry out a subsequent quantitative analysis.In the course of the research, an experimental method is proposed for obtaining primary data characterizing the shape of individual meridional sections of the package. An experimental setup has been developed that makes it possible to obtain data and store it in digitized form, and a method for converting the data obtained into a volumetric geometric model of a textile package.It is established that the developed model allows to obtain a number of single indicators of deviation of the shape of the bobbins from the given one and further to work on the formation of a complex index for evaluating the quality of the bobbin shape. Complex evaluation of the quality of the package form can be obtained by the weighted average method. The average weighted index is constructed as a dependence, the arguments of which are single quality indicators and parameters of their weight.The estimation of applicability of the developed complex indicator for the analysis of the form of packages is carried out. To do this, the package lot analysis is carried out, which confirmed the reproducibility of the package shape analysis process with the help of the proposed complex indicator, as well as the correspondence of the estimates obtained by the proposed method to visual estimates.The method of complex quantitative evaluation of the form of packages, presented in this paper, allows to carry out optimization experiments and on their basis to assign such adjustable parameters of winding mechanisms that will allow to receive packages of the required quality. When developing new winding equipment, it will be possible to lay down the necessary mechanisms for regulating the winding process.
