CONTROL AND MANAGEMENT APPARATUS FOR PRODUCTION AND PACKAGING LINES FOR PAPER ROLLS

摘要

Downstream of the cutters (TR1, TR1', TR2, TR2') linked to the two magazines (MAG1, MAG2) collecting the paper rods generated by the rewinding machines (RIB1, RIB2), flow splitting equipment (D1, D1', D2, D2') is provided. One product flow originating from the splitter linked to one magazine and one product flow originating from another splitter linked to another magazine reach a flow adder (S12, S12') performing the inverse function of joining together in one flow the two product flows to feed them to a corresponding packaging machine (M1, M2). The other product flows generated by the splitting equipment fed singularly to respective packaging machines (M3, M4, M5, M6). The status of the various machines is monitored by an electronic process nit (CPU), which can be programmed and interrogated by suitable means (PC).In the event of slowdown or stoppage of one of the shared machines (M1, M2), the missing flow of products, leads to an automatic balanced accumulation of rods in the magazines of the two lines. Via these same shared machines it is also possible to take up from the magazines accumulations of rods after any slowdown.The sharing the two magazines in the product accumulation phase improves the efficiency of the plant.
