Abstract
A cleaning system for cleaning a band circulating in a paper making machine; the system comprising: at least one detecting device configured to detect at least one parameter indicative of the cleaning conditions of the band on at least one portion of the band; at least one cleaning device provided with at least one nozzle to create a jet of a cleaning fluid; the nozzle being arranged so that the jet of cleaning fluid is directed towards the band; a control device configured to regulate the cleaning device on the basis of the at least one parameter indicative of the cleaning of the band.
Claims13
A cleaning system for cleaning a band (2) circulating in a paper making machine (3);
- the system (1) comprising:
- at least one detecting device (4) configured to detect at least one parameter indicative of the cleaning conditions of the band (2) on at least one portion of the band (2);
- at least one cleaning device (5) provided with at least one nozzle (9) to create a jet of a cleaning fluid;
- the nozzle (9) being arranged so that the jet of cleaning fluid is directed towards the band (2);
- a control device (6) configured to regulate the cleaning device (5) on the basis of the at least one parameter indicative of the cleaning conditions of the band (2);
- a first moving assembly (7) configured to move the detecting device (4) along a direction (A) transversal to the circulation direction (S1) of the band (2);
- the detecting device (4) being active during the movement so as to detect a plurality of parameters indicative of the cleaning conditions of the band (2) in different portions of the band (2);
- wherein the first moving assembly (7) comprises:
- a first moving device (20);
- a first carriage (19) moved by the first moving device (20) and coupled to the detecting device (4);
- a first guide (18) configured to guide the movement of the first carriage (19) and extending along an axis (A) substantially transversal to the circulation direction (S1) of the band (2);
- a second moving assembly (8) configured to move the cleaning device (5) along a direction (A) transversal to the circulation direction (S1) of the band (2), wherein the second moving assembly (8) comprises:
- a second moving device;
- a second carriage moved by the second moving device and coupled to the cleaning device (5);
- and
- a second guide configured to guide the movement of the carriage and extending along an axis (A) substantially transversal to the circulation direction (S1) of the band (2);
- and
- a supporting frame (17) supporting the second guide (18);
- the supporting frame (17) comprising two substantially identical uprights (22) coupled to the second guide (18) and resting on the floor or on an appropriate support base at the sides of the band (2);
- wherein the second guide (18) and the uprights (22) define a bridge structure.
