Method for the step-by-step guidance of a machine operator of an extrusion device when changing from an application formula to a subsequent formula

A method for changing from an application formula to a subsequent formula in an extrusion device for a film machine,

• wherein the film machine comprises an optical display,
• the method comprising the following steps:
• identifying, by the film machine, a manual formula change request from a machine operator,
• displaying, by the display, the formula change request for the machine operator, wherein displaying the formula change request is a request to the machine operator, to now perform subsequent necessary manual steps himself,
• displaying, by the display, at least one concluding step to be performed for an application formula, wherein the at least one concluding step is performed in order to completely end the application formula,
• identifying, by the film machine, a manual confirmation input from the machine operator for the at least one concluding step,
• displaying, by the display, at least one preparatory step to be performed for a subsequent formula,
• identifying, by the film machine, a manual confirmation input from the machine operator for the at least one preparatory step, and
• concluding, by the film machine, a change from the application formula to the subsequent formula,
• wherein the method provides a step-by-step guidance of the machine operator of the extrusion device for the film machine when changing from the application formula to the subsequent formula,
• wherein the step of concluding the change is performed when the specified preparatory step and concluding step have been finalized and confirmed, so that a control device can now switch over into a normal operating mode for the production of the subsequent formula,
• wherein the film machine provides a feedback guidance of the machine operator wherein the feedback guidance comprises an interaction between the actions of the machine operator, automatically performed steps of the change, and corresponding return confirmations that the manual steps were performed,
• wherein the display for displaying the at least one concluding step or the at least one preparatory step is at a location of the film machine where the corresponding step is performed, and
• wherein the confirmation of the at least one concluding step is identified at a location where the corresponding identifying step is performed.
