Abstract:
1. An apparatus for production of cigarette packs of the hinge-lid pack type from pack and lid blanks, each pack comprising a box part and a lid, each pack having front, rear and side faces delimited by upright pack edges, said apparatus comprising: a) means for producing the packs whose said pack edges are right-angled, round or beveled, said means comprising a folding turret having a plurality of shaping pockets in which the blanks are folded around the pack contents during the production of the cigarette packs, said folding turret having stationary, immovable shaping elements, and shaping subassemblies with displaceable rounding tools, said folding turret being arranged in respective configurations corresponding to a cross-sectional design of the pack edges; b) means to withdraw said displaceable rounding tools in an inoperative position when said displaceable rounding tools do not correspond to the type of pack to be produced; c) means to interchange said folding turret having said shaping pockets with a second folding turret having a plurality of shaping pockets correspond to a type of pack to be produced and with a respective shape of the pack edges, d) wherein the interchangeable folding turrets are provided with first sensor, and the shaping subassemblies are provided with a second sensor, said first and second sensors having scanning means to scan and to produce scanned data, e) central control means, connected to the first and second sensors for checking the scanned data of the folding turrets that are to be exchanged with respect to correct allocation thereof; means for generating an error signal on an occurrence of an incorrect said allocation, the central control means checking the scanned data of the second sensor of the shaping subassemblies for the purpose of checking the position of the rounding tools corresponding to the type of pack to be produced in each case; and means for generating an error signal on an occurrence of an incorrect said position of the rounding tools corresponding to the type of pack to be produced.
