Abstract
A simulated cold extrudate profile, which defines a profile of an extrudate in a cooled state, by a cold profile modeling unit, the determination of a deviation of the cold extrudate profile from a specified extrudate profile by means of a comparison unit and an optimization, based on the deviation, of the process parameters by means of a parameter determining unit, in such a way that a deviation of a cold extrudate profile that is produced from the extrudate profile that is specified becomes small.
Claims14
An apparatus for controlling an extrusion installation having at least one extrusion head for shaping at least one extrudate, the apparatus comprising:
- a profile determining unit configured to determine a warm extrudate profile of at least one extrudate, wherein the warm extrudate profile defines geometric data of the extrudate in a warm state;
- a first cold-profile modeling unit configured, on the basis of the warm extrudate profile and initial process parameters, to parameterize, using artificial intelligence, an extrudate model which determines a first cold extrudate profile of the extrudate in a cooled state;
- a comparison unit configured to determine a first deviation between the determined first cold extrudate profile and a specified extrudate profile,
- a parameter determining unit configured, using the first deviation, to optimize process parameters and to determine changed process parameters, such that a deviation of a cold extrudate profile dimension that is produced from the specified extrudate profile is less than two percent;
- a selection unit configured to select, during extrusion, the changed process parameters as the input for an actuating unit if the deviation is less than or equal to a threshold value of less than two percent, and
- the actuating unit configured to control the extrusion installation with the changed process parameters in order to produce a second warm extrudate.
A computer-implemented method for controlling an extrusion installation, comprising:
- a) determination of a warm extrudate profile of at least one extrudate by a profile determining unit, wherein the warm extrudate profile defines geometric data of the extrudate in a warm state,
- b) parameterization, using artificial intelligence, of an extrudate model by a first cold profile modeling unit on the basis of the warm extrudate profile and initial process parameters,
- wherein the extrudate model determines a first cold extrudate profile of the extrudate in a cooled state,
- c) determination of a first deviation between the determined first cold extrudate profile and a specified extrudate profile by a comparison unit,
- d) optimization of process parameters and determination of changed process parameters using the first deviation by a parameter determining unit, such that a deviation of a cold extrudate profile dimension that is produced from the specified extrudate profile is less than two percent,
- e) selection, during extrusion, of the changed process parameters as the input for an actuating unit of the extrusion installation if the deviation is less than or equal to a threshold value of two percent, by a selecting unit, and
- f) control of the extrusion installation with the changed process parameters by an actuating unit.
