Definitions

  • This invention relates to the technical sector of machines for packaging products.
  • the invention relates to a machine for packaging articles in the tobacco industry, such as, for example, cigarettes, using hinged-lid packets.
  • Hinged-lid packets are packets substantially formed by a box-shaped body, which defines a containment space inside of which the product is enclosed, and a lid hinged to an open end of the container body to rotate between an open position and a closed position of the latter.
  • Each packet is generally made from a blank which has a plurality of crease lines, which substantially delimit the various panels which will form the walls of the container following folding of the blank.
  • Prior art packing machines form the packet and wrap the blank around the product.
  • the prior art machines wrap the group in a first wrapping material, usually aluminium, making a partial wrapping, proceeding in subsequent steps to the making of the complete packet.
  • the prior art machines comprise a succession of folding stations in which the blank, after having been coupled to the partial wrapping, is progressively folded around it to form the complete packet.
  • the Applicant has observed that the prior art has drawbacks which make the use not very well performing and unsuitable for the requirements of the sector.
  • the technical purpose which forms the basis of the invention is to propose a packaging machine which overcomes at least some of the above-mentioned disadvantages of the prior art.
  • the aim of the invention is to provide a packaging machine which is able to be effectively integrated inside a production plant, maintaining high levels of quality and production.
  • the invention describes a machine for packaging articles in the tobacco industry, in particular for packaging cigarettes using hinged-lid packets, which comprises a first section which moves intermittently and a second section which moves continuously.
  • a succession of groups of articles are fed to the first section and at least a first wrapping material designed to wrap around each group of articles to obtain a semi-finished packet defining a partial wrapping of each group of articles, in particular an inner wrapper.
  • the second section which is configured to receive the semi-finished packets from the first section, and is fed with at least a second wrapping material, in particular a blank made of cardboard, intended to wrap the semi-finished packet to obtain a complete packet.
  • a second wrapping material in particular a blank made of cardboard
  • this structure makes it possible to optimise the process for transferring the articles to the packaging machine and their subsequent processing to make the complete packet.
  • the numeral 100 denotes in general the machine for packaging articles in the tobacco industry according to the invention, which will hereinafter be referred to as the machine 100.
  • the machine 100 is particularly designed and suitable for packaging articles in the tobacco industry, such as, for example, cigarettes, by means of hinged-lid packets and comprises a first section 100a which moves intermittently and a second section 100b which moves continuously.
  • the first section 100a is fed, from production or transport processes situated upstream of the machine 100, with a plurality of articles which will be divided into groups "A" and at least a first wrapping material "B” designed to wrap each group "A” of articles to obtain a semi-finished packet "C" which defines a partial wrapping.
  • the first wrapping material "B" is, for example, defined by a web of aluminium, tin foil or other paper suitable for covering in a sealed fashion a group of cigarettes retaining the aroma.
  • the second section 100b is fed from the first section 100a with the semi-finished packet "C" and, from production or transport processes situated upstream of the machine 100, at least a second wrapping material "D", such as, for example, a cardboard blank, designed to wrap the semi-finished packet "C” to make the complete packet "E".
  • a second wrapping material "D" such as, for example, a cardboard blank
  • This functional separation of the machine 100 guarantees a correct integration of the machine 100 inside the production plant in which it operates, optimising in particular the process for feeding the articles to be processed.
  • the machine 100 is able to process in parallel groups "A" of articles which it receives from the upstream processes, making a semi-finished packet "C” which is then fed to the portion of the machine 100 which operates continuously and is designed for making the complete packet "E".
  • the making of the semi-finished packet "C” makes it possible to guarantee the containment of the product "A" inside the machine 100, from when it is received in the first section 100a until it is transferred to its second section 100b, where the complete packet "E" will be made.
  • the machine 100 comprises an interface conveyor 110, interposed between them and configured to receive in an intermittent fashion the semi-finished packets "C" from the first section 100a and then transfer them continuously to the second section 100b.
  • the interface conveyor 110 therefore makes it possible to mediate the passage of the semi-finished packets "C" from that part of the machine 100 which makes them and which operates intermittently to that part of the machine 100 designed to make the complete packet "E" and which operates continuously.
  • the interface conveyor 110 comprises a conveyor belt 111 supported on a support 112 and having a plurality of drawers 113 designed to receive and retain the semi-finished packets "C" arriving from the first section 100a.
  • the conveyor belt 111 defines a closed path which has a forward branch 111a and a return branch 111b.
  • the forward branch 111a defines a straight forward path facing the first section 100a wherein the semi-finished packets "C" can be transferred intermittently to the interface conveyor 110 from the first section 100a.
  • the return branch 111b defines a straight return path, parallel to the straight forward path, facing the second section 100b, wherein the semi-finished packets "C" can be transferred continuously from the interface conveyor 110 to the second section 100b.
  • the forward branch 111a has a discontinuous feed speed, in particular intermittent, whilst the return branch 111b has a continuous and constant feed speed.
  • the support 112 is movable along a sliding direction "X" parallel to the path defined by the forward branch 111a and the return branch 111b, according to a loading movement and a repositioning movement.
  • the support 112 is always moved along the sliding direction "X" with a feed direction opposite the following movement.
  • the support 112 is moved alternately along the sliding direction "X" according to a loading movement, therefore with a first feed direction, or according to the repositioning movement, therefore with a second feed direction opposite to the first feed direction.
  • the speed of movement of the support 112 is of equal module and direction and opposite sense relative to a tangential speed of movement of the forward branch 111a of the conveyor belt 111 in such a way that the drawers 112 present in the forward branch 111b are substantially stationary relative to the first section 100a to receive from it semi-finished packets C, with intermittent motion.
  • the support 112 moves along the sliding direction "X" at a speed such as to compensate overall for the speed of rotation of the forward branch 111a of the conveyor belt 111 relative to the support 112 (for example, by feeding the support 112 and making the forward branch 111a slide backwards).
  • drawers 113 present in the toward branch 111a are substantially fixed, both relative to the first section 100a and relative to the second section 100b.
  • the drawers 113 present in the return branch 111b have an overall speed, relative to the first section 100a and to the second section 100b, greater than only the speed of rotation of the conveyor belt 111, since the positive contribution given by the speed of movement of the support 112 will be added, which has the same direction as the tangential speed of movement of the return branch 111b.
  • the speed of rotation of the conveyor belt 111 in the return branch 111b added to the speed of movement of the support 112 will be equal to a predetermined transfer speed designed to allow the continuous transfer of the semi-finished packets "C" from the interface conveyor 110 to the second section 100b.
  • the speed of movement of the support 112 is equal to a tangential speed of movement of the forward branch 111a of the conveyor belt 111 in such a way that the drawers 113 present in the forward branch 111a are movable relative to the first section 100a and in particular with a speed greater than the speed (constant) with which the drawers 113 of the return branch 111b move.
  • the drawers 113 present in the return branch 111b have an overall speed, relative to the first section 100a and to the second section 100b, which is less than the speed of rotation of the conveyor belt 111, since the contribution given by the speed of movement of the support 112 will be subtracted, which in this case has a direction opposite to the tangential speed of movement of the return branch 111b.
  • the speed of rotation of the conveyor belt 111 in the return branch 111b added to the speed of movement of the support 112 is in any case equal to the predetermined transfer speed.
  • the rotation speed of the conveyor belt 111 and of the movement of the support 112 are modified, only one or both, depending on whether the loading or repositioning movement is performed, in such a way that the drawers 113 present in the return branch 111b are movable relative to the second section 100b again according to the transfer speed, which remains constant irrespective of the movement performed by the support 112, in such a way as to allow continuous transfer to the second section 100b of the semi-finished packets "C" which have been received from the first section 100a.
  • the first section 100a comprises a grouping station 120, a station 130 for feeding the first wrapping material "B" and a wrapping station 140.

  • the bottom portion of the hopper 121 is divided into a plurality of lower mouths 121b arranged side by side horizontally and each divided by a plurality of walls into substantially vertical channels arranged side by side horizontally.
  • Each of the channels is designed to receive into it a stack of articles superposed on each other.
  • Suitable extractor elements extract the articles in succession from the bottom ends of the channels, at each bottom mouth 121b of the hopper, to form them in separate groups "A" for example by releasing layers to form a group of standard cigarettes (for example twenty cigarettes).
  • the grouping station 120 comprises a grouping conveyor 122 which has a plurality of drawers 122a designed to receive respective groups "A" of articles after they have been formed at the outfeed from the hopper 121.
