Man­u­fac­tur­er-inde­pen­dent Wind­ing Application

Test-Set­up

In order to be able to test the soft­ware under approx­i­mate­ly real con­di­tions, a mod­el from Fis­chertech­nik was built with elec­tri­cal hard­ware. A feed unit in the mid­dle between the two wind­ing units ensures a con­stant web speed. In a real appli­ca­tion, for exam­ple, a cal­en­der could be used here. The dancer reg­u­la­tion was imple­ment­ed on the left side. With this method, the mate­r­i­al is guid­ed behind the winder via a ver­ti­cal­ly freely mov­able dancer. The dancer should always stay in a mid­dle posi­tion, the reg­u­la­tion reacts to devi­a­tions from this posi­tion. The dis­place­ment mea­sure­ment is car­ried out by a slide poten­tiome­ter. For the sec­ond method, the ten­sion con­trol, a fixed deflec­tion roller is used, with force sen­sors attached to the foun­da­tion. Here the ten­sion is used as a con­trol variable.

Expan­sion of the pos­si­ble use

The Siemens library LCon is used for the PLC-based con­trol. It already con­tains all the nec­es­sary com­po­nents for com­pen­sat­ing of fric­tion and accel­er­a­tion and for imple­ment­ing the var­i­ous con­trol process­es. The mod­ules were used and para­me­ter­ized in soft­ware for con­trol­ling the entire sys­tem. Using the mod­el, a com­plete man­u­fac­tur­er-inde­pen­dent imple­men­ta­tion of both oper­at­ing modes could be achieved.
All data aris­ing in the process are vis­i­ble on the user inter­face on the sys­tem, con­trol para­me­ters can be adjust­ed there direct­ly. This not only results in greater flex­i­bil­i­ty, but also faster com­mis­sion­ing is pos­si­ble. The mod­el is used for fur­ther devel­op­ments and training.
