Abstract:
A method of making a brand change, on an automatic production system for processing tobacco articles and which produces a first product from first materials; the method has the steps of: stopping the automatic production system once production of the first product is completed; feeding second materials onto the automatic production system; restarting the automatic production system to commence production of a second product from the second materials; checking all the second products in a first lot to ensure each second product in the first lot conforms with production specifications; externally marking each second product in the first lot conforming with production specifications; and generating a pass signal when a given number of consecutive second products conforming with production specifications is produced.
Abstract:
A method and unit for applying labels to products fed by a conveyor along a conveying path; a number of pickup heads are fed along a feed path to withdraw the labels successively from a feeder and apply the labels successively to respective products on the conveyor; and, in the event of stoppage or malfunctioning, the pickup heads are fed along a reject path, adjacent to the feed path, to transfer at least some of the labels on the pickup heads to a collecting device.
Abstract:
A label feeder unit associated with a machine for packing tobacco products holds a stack of labels placed in a channel presenting an infeed end, and an outfeed end from which the labels are released to a take-up station, then picked up singly and transferred to a further unit of the machine. The outfeed end of the channel incorporates a transfer mechanism comprising a pair of contrarotating rollers placed on either side of the channel at a distance less than the width of the stack in such a way as to intercept the labels and transfer them to the take-up station, which is movable relative to the outfeed end of the channel under the pressure transmitted to the station by the labels taken up between the rollers. The transfer mechanism forms part of a feedback control loop by which the pressure registering through the labels at the take-up station is kept within prescribed limits.
Abstract:
A rigid container for tobacco items, defined by a tubular lateral wall (11) and by at least one end wall (6), and wherein one of the two walls (6, 11) has at least one inwardly concave portion (13; 82; 91; 96; 102; 113), and the other wall has at least one flat portion (8; 114), which mates with the concave portion (13; 82; 91; 96; 102; 113) along a convex outer edge portion (10, 115) of its own, and is formed from a panel (6′; 6′, 6″; 121a, 122a) having a first portion (6′a; 6′a, 6″a; 128) corresponding to the flat portion (8; 114), and a peripheral second portion defined by at least one curved strip (20; 20′, 20″; 127) bounded internally by a curved crease line (19; 19′, 19″; 126) extending along the convex outer edge portion (10; 115); the strip (20, 20′, 20″; 127) being folded squarely, by drawing, to define a convex border (23; 129) extending along the convex outer edge portion (10; 115), and being made integral with an inner surface of the concave portion (13; 82; 91; 96; 102; 113).
Abstract:
Packets of prismatic geometry referable to a longitudinal axis, presenting two larger side faces, two smaller flank faces and two end faces, are overwrapped by a method including a step in which each packet, enveloped initially by a tubular wrap projecting beyond the two end faces, is inserted into a holder of a transfer wheel in such a way that two appendages of the tubular wrap projecting at either end from a first flank face of the packet are flattened over the end faces; the appendages are pinned immediately along two lines coinciding substantially with the corner edges of the end face as the packet enters the relative holder, and held stably in position during a subsequent step of transferring the single packets from a feed station to an outfeed conveyor.

Abstract:
A method and device for folding an end portion of a substantially elliptical-section, tubular wrapping for a group of cigarettes, whereby the end portion of the tubular wrapping is folded by forming three first and three second folded flaps located on opposite sides of a major axis of the elliptical section of the tubular wrapping; the first and second flaps being defined respectively by a respective central flap and by two respective lateral flaps, each of the second flaps being specular with a corresponding first flap, and being located between the major axis of the elliptical section and a packing wheel supporting the tubular wrapping; the first flaps being folded first, commencing with the first central flap; and the second flaps being folded subsequently, commencing with the second lateral flaps.
Abstract:
A supply unit and a user unit employed in the manufacture of tobacco products, typically cigarettes and the like, are linked by a duct along which a mass of the cigarettes is advanced from the outfeed of the supply unit toward the infeed of the user unit. The advancing mass of cigarettes is parted at an intermediate zone of the duct either by rods or by a pair of frames, in such a way as to create a void that will accommodate a trolley directed into the duct from a housing by an elevator; once inside the duct, the trolley proceeds to push the mass of cigarettes from the intermediate zone toward the inlet of a hopper in such a way as to empty the duct completely, for example when changing over from one brand of cigarette to another. To advantage, the trolley is composed of two articulated structures so that its geometry and dimensions can be varied to match the variations in geometry and depth of the duct.
Abstract:
Groups containing a given number of products are produced using a transfer assembly, wherein a first, pocket-type output, conveyor of a production machine, and a second, pocket-type input, conveyor of a group-forming machine move continuously in a first and, respectively, second direction opposite each other, and are connected to each other by a pocket-type transfer member, which is interposed between the first and second conveyor, and is operated to selectively rotate about an axis of rotation crosswise to the first and second conveyor; or to translate, together with the second conveyor, crosswise to the axis of rotation to compensate for one or more voids on the first conveyor; or to translate, together with the first conveyor, crosswise to the axis of rotation to form, on the second conveyor, a succession of voids in time with the group-forming machine.
Abstract:
A multipurpose cartoning machine for packets of cigarettes, having a packet conveying assembly wherein a first conveyor feeds single packets, arranged in an orderly succession on edge, to an accumulating station for forming subgroups of packets placed flat one on top of the other, and a second conveyor is associated with the first conveyor to receive the packets conveyed by the first conveyor and to feed the packets to a packing device; the conveying assembly assuming a first configuration wherein the second conveyor is connected to the first conveyor at the accumulating station to receive, from the first conveyor, a succession of subgroups of packets laid flat, and a second configuration wherein the second conveyor is connected to the first conveyor upstream from the accumulating station to receive an orderly succession of single packets positioned on edge.
