Definitions

  • the present invention relates to a unit and a method for supplying sheets of wrapping material for cigarette packets and a machine for packing said packets.
  • cigarette packets are divided into packets of the soft type and rigid type, the latter frequently having a hinged lid.
  • the soft packets comprise a group of cigarettes enveloped by an internal wrapping obtained from a sheet of wrapping material and by an external label surrounding the internal wrapping with the exclusion of the top part thereof.
  • the rigid packets comprise a group of cigarettes enveloped by an internal wrapping obtained from a sheet of wrapping material and an external casing obtained by means of folding of a blank, typically made of cardboard, defining a box-shaped body and a lid hinged with the said box-shaped body.
  • the wrapping sheet generally consists of tin foil or a paper material.
  • these cartons must be made so that the packets arranged alongside each other in the packaging have wrapping sheets of different types, for example made of the same material, but with a different colour, or even made of different material.
  • Document GB 2 132 975 A discloses a feed unit according to the preamble of claim 1.
  • the object of the present invention is to provide a unit and a method for supplying sheets of wrapping material for cigarette packets able to satisfy the abovementioned requirement.
  • this object is achieved by a unit and a method for supplying sheets of wrapping material for cigarette packets, comprising the technical features contained in one or more of the accompanying claims.
  • first wrapping material M1 and the second wrapping material M2 may both be made of the same paper material, but may differ in terms of surface colouring or may be made of different materials such as paper material and tin foil.
  • Each wrapping sheet F1, F2 has preferably a long rectangular form.
  • first sheets F1 will be used to refer to the wrapping sheets of the first wrapping material M1 and the term “second sheets” F2 will be used to refer to the sheets of the second wrapping material M2.
  • the wrapping machine 100 comprises a feed unit 1 supplying the wrapping sheets F1, F2 and a station 5 for wrapping groups G1, G2 of cigarettes G1, G2 using these wrapping sheets F1, F2.
  • the feed unit 1 is intended to supply the wrapping sheets to the wrapping station 5.
  • the feed unit 1 is designed to supply in a cyclically alternating manner the first sheets F1 along a first feed path P1 and the second sheets F2 along a second feed path P2.
  • the machine 100 is provided with a first reel B1 which is unwound so as to supply a first continuous strip N1 of the first type of material M1.
  • the first reel B1 is mounted on a motor-driven spindle 16 which can be imparted a rotational movement so as to unwind and supply the first strip N1.
  • the machine 100 also comprises a plurality of rollers 18, 19, 20, 21, 22 which are intended to be partly flanked by the first strip N1.
  • the rollers 18, 19, 20, 21, 22 define a path P4 for supplying the first strip N1, namely a path for unwinding the first strip N1 from the reel B1.
  • a station for forming weakening lines on the first strip N1 is shown schematically and denoted by 35.

  • Supplying of the second sheets F2 along the second feed path P2 will be described more briefly than supplying of the first sheets F1 since it is similar to supplying of said first sheets F1.
  • the machine 100 is provided with a second reel B2 which is unwound so as to supply continuously a second strip N2 of the second type of material M2.
