Procedure for polishing elements in marble, granite or hard stone in general and associated device

摘要

Procedure for polishing elements in marble, granite or hard stones in general, associated with a device comprising a plurality of polishing stations 14 arranged in line and cooperating with a conveyor means 11 which advances in a substantially linear manner and feeds the piece to polish 13 between said stations 14, the procedure envisaging at least one phase 20 for reading and/or recognising the profile of the piece to polish 13 upstream from the first polishing station 14a and at least one phase 23 for washing and drying the polished surface downstream from the last polishing station 14b, the procedure being managed by a drive and control unit 17, at least downstream from the washing and drying phase 23, envisaging an in-line phase 24 for measuring the degree of brilliance of at least part of the surface of the polished piece 13 with consequent parameterisation of the brilliance value measured, said measurement phase 24 being associated at least with means for identifying the brilliance result obtained. Device for polishing elements in marble, granite or hard stones in general, comprising a plurality of polishing stations 14 arranged in line and cooperating with a conveyor means 11 which advances in a substantially linear manner and feeds the piece to polish 13 between said stations 14, the device comprising at least means 15 for reading and/or recognising the profile of the piece to polish 13 located upstream from the first polishing station 14a, and at least means of washing 18 and drying 19 the polished surface located downstream from the last polishing station 14b, said polishing device 10 having at least one drive and control unit 17 set up for the management and operation of the polishing device, comprising at least one unit 25 for measuring the degree of brilliance of at least part of the surface of the polished piece 13, located in line and downstream from said means of washing 18 and drying 19, said measurement unit 25 being associated with said drive and control unit 17 for providing at least one parameterised value corresponding to the brilliance value of said surface of the polished piece 13.
