Definitions

  • the present invention relates to a method of producing rigid hinged-lid packets of cigarettes.
  • the present invention may be used to advantage on packing machines for producing packets of cigarettes comprising a cup-shaped body and a lid coaxial with the cup-shaped body, and which are defined laterally by two small lateral walls, each defined by two longitudinal tabs gummed one on top of the other.
  • each packet is normally formed by step-feeding a blank of packing material and a respective inner wrapping, defined by a group of cigarettes enclosed in a sheet of foil paper, in a given first direction along a given first path, and gradually folding the blank about the inner wrapping to form an incomplete packet of cigarettes, i.e. a packet in which one longitudinal tab in each pair projects laterally from a front surface of the incomplete packet, whereas the other tab in the pair is folded squarely.
  • the incomplete packet is step-fed, crosswise to the longitudinal tabs, through a transfer station where it is engaged axially by a transfer device moving back and forth across the first path and in a second direction crosswise to the first direction to transfer the incomplete packet to a conveying device extending along a second path and through a gumming station.
  • the conveying device On receiving the incomplete packets, the conveying device feeds them in steps, with the respective longitudinal tabs parallel to the second direction, through the gumming station where given portions of the tabs are gummed, and then through a folding station where the tabs are folded squarely and gummed to the respective already-folded tabs to form a complete packet.
  • the above method has several drawbacks, mainly due to the packets being transferred from the first to the second path. That is, the transfer device, despite being relatively slow as compared with the conveying devices to which it is connected, engages each packet sharply in an attempt to speed up the transfer operation. Being step-operated, however, there is a limit to the speed at which such transfer devices can be operated without incurring vibration capable of impairing the structure and reliability of the packing machine.
  • a method of producing rigid hinged-lid packets of cigarettes having respective small lateral walls, each defined by two superimposed longitudinal portions comprising the steps of feeding a succession of blanks of packing material along a given path and in a given traveling direction by means of first conveying means, each blank comprising a central panel, two longitudinal lateral panels connected to the central panel and defining a first of said two longitudinal portions, two transverse end panels connected to the central panel, two front panels connected to the end panels, and, for each front panel, a further two longitudinal lateral panels defining a second of said two longitudinal portions, and each blank being fed along said path with the longitudinal lateral panels crosswise to said traveling direction; folding each blank to form a respective incomplete packet having said front panels parallel to said central panel, the respective first longitudinal portions folded squarely with respect to the central panel, and the respective second longitudinal portions coplanar with the front panels and projecting laterally with respect to the respective first longitudinal portions, the first and second longitudinal portions of each incomplete packet being arranged crosswise to said traveling direction

  • the end portion of portion 72 of branch P2 is so formed that pocket 58, on gradually approaching belt 50, permits insertion of belt 50 inside opening 66, and, as panel 25 contacts upper surface 55 of conveying branch 52, i.e. as pocket 58 begins traveling along portion 71 of branch P3, a transverse projection 54 collides with surface 76 of packet 2a at a speed V2 greater than the traveling speed V1 of packet 2a.
  • pocket 58 and projection 54 provides for extracting packet 2a longitudinally from seat 63, and for inserting packet 2a inside a conveying pocket 53 and inside channel 86 the instant packet 2a is withdrawn fully from seat 63.
