Apparatus for controlling machines for cleaning of fibers

Abstract

Machine setting values containing similar functions are grouped together as a group in a setting value table and as many tables, as present groups, are correlated to machine operating elements. Parameter vectors are obtained from each table, effectuating a predetermined machine setting and the totality of the parameter vectors represent (for instance along a diagram axis) settings for the associated operating element. The group formation of setting values for a fine cleaning machine encompasses, for instance, setting values of the knife or carding element-distance from the beater circle, the point density of the carding element, the clamping distance of the feed trough or funnel from the clothing of the opening roller, and the rotational speed of the opening roller. These setting values are grouped together in a first group and included in a first table for forming parameter vectors for the cleaning intensity. The offset distance between a fiber guide and knife and the length of the separation gap between the knife and fiber guide are grouped together in a second group and included in a second table for the formation of parameter vectors for the quantity of waste. The setting elements of the fine cleaning machine can be linked by these parameter vectors and characteristic numbers of the parameter vectors are correlated to a respective operating element, which operating elements, due to linking of the setting elements by the table-linking, in each setting collectively define a working point of the fine cleaning machine.
