Abstract

Sposób nawijania bez tulejowego folii rozciągliwej oraz trzpień obrotnicy nawijarki do nawijania bez tulejowego folii rozciągliwej, charakteryzujący się tym, że nawija się folię w pierwszej fazie bez rozciągania, kontaktowo z dociskiem momentowym o regulowanej sile naciągu, którą nawija się do średnicy zwoju równej średnicy rolki (10), podpierającej kieł (9), po czym po dojściu zwoju do średnicy rolki (10), podpierającej kieł (9) przechodzi się w tryb nawijania szczelinowego, które realizowane jest przez oprogramowanie maszyny w sterowniku PLC, przy czym podczas nawijania szczelinowego folii trzpień, umieszczony na obrotnicy, odsuwa się cyklicznie od wałka nawijającego na odległość stanowiącą grubość nawijanej foli powiększonej o wielkość 5 do 7 µm na jeden obrót trzpienia. Trzpień obrotnicy nawijarki składa się z rdzenia wewnętrznego (2) oraz z tulei zewnętrznej (1), przy czym rdzeń wewnętrzny (2) ma wewnętrzną komorę powietrzną (4) z rozmieszczonymi otworami (5) wypływu powietrza do komory utworzonej pomiędzy płaszczem zewnętrznym rdzenia wewnętrznego (2) a płaszczem wewnętrznym tulei zewnętrznej (1) stanowiącą komorę zewnętrzną powietrza (3), zaś wewnętrzna komora powietrzna (4) połączona jest przelotowo z piastą trzpienia (8) i zakończona z wyprowadzonym na zewnątrz zaworem (7) sprężonego powietrza, przy czym tuleja zewnętrzna (1) ma otwory (6) wypływu powietrza na zewnątrz tulei zewnętrznej (1).A method of winding without a sleeve for stretchable film and a winding spindle of the winder for winding without a sleeve for stretchable film, characterized by the fact that the film is wound in the first phase without stretching, in contact with a momentary clamp with an adjustable tension force, which is wound to a coil diameter equal to the diameter of the roll ( 10), supporting the center (9), and then, after the coil reaches the diameter of the roll (10) supporting the center (9), the slot winding mode is switched to, which is carried out by the machine software in the PLC controller, and during the slot winding of the foil, the spindle , placed on the turntable, moves cyclically away from the winding roller to a distance equal to the thickness of the wound film increased by 5 to 7 µm per one revolution of the spindle. The winder spindle consists of an inner core (2) and an outer sleeve (1), where the inner core (2) has an internal air chamber (4) with spaced holes (5) for air outflow into the chamber formed between the outer jacket of the inner core ( 2) and the inner jacket of the outer sleeve (1) constituting the outer air chamber (3), and the inner air chamber (4) is connected through-through to the pin hub (8) and ends with a compressed air valve (7) leading outside, wherein the sleeve the outer sleeve (1) has holes (6) for air flow outside the outer sleeve (1).
