Abstract

Dispositivo per l'azionamento di un sistema a rulli per il trasporto di materiale in fogli, in particolare pellicole di fosforo eccitabile e/o lastre radiografiche, a velocità costante, in un dispositivo di rilevazione e/o esposizione degli stessi, caratterizzato dal fatto che perlomeno un rullo (1a) del sistema (1) è azionabile; dal fatto che un rotismo a frizione (2) con un albero di uscita (2a) per ciascun rullo (1a) azionato è installato in modo che di volta in volta un albero di uscita (2a) ed un albero (1b) di un rullo (1a) azionato, risultino coassiali fra loro e che siano collegati tramite un giunto di uscita (5); dal fatto che un albero di ingresso (2b) del rotismo a frizione (2) è coassiale ad un albero (3b) di un motore di azionamento (3), essendo collegato mediante un giunto di ingresso (4) con un albero (3b) stesso; e dal fatto che il motore (3) è un motore a passi.Device for driving a roller system for the transport of sheet material, in particular excitable phosphorus films and / or radiographic plates, at constant speed, in a device for detecting and / or exposing them, characterized in that at least one roller (1a) of the system (1) is operable; by the fact that a friction gear (2) with an output shaft (2a) for each driven roller (1a) is installed so that each time an output shaft (2a) and a shaft (1b) of a roller (1a) operated, are coaxial with each other and connected by an outlet joint (5); by the fact that an input shaft (2b) of the friction gear (2) is coaxial with a shaft (3b) of a drive motor (3), being connected by an input joint (4) with a shaft (3b) same; and the fact that the motor (3) is a stepping motor.
