Definitions

  • the apparatus described here is of the type comprising:
  • the semi-finished pack that is pushed out of the forming wheel is pressed by two opposing forces, on its larger walls, and, in this condition, its two outer flaps, still to be folded, of the smaller side walls, are folded against the corresponding inner flaps to form these walls and complete the pack.
  • the aforementioned opposing device configured to act in opposition to the pusher member, is constituted by a counter-pusher arranged to engage the aforesaid second wall of the semi-finished pack and move simultaneously with the pusher member, accompanying the displacement of the pack, and exerting thereon a force opposite to that exerted by the pusher member.
  • the present invention proposes to provide an improved solution with respect to the known apparatuses indicated, in particular, with a simpler structure and a more reliable operating mode.
  • the pack shown is a "hinged-lid" pack type.
  • the casing 2 consists of a container 2A, which contains the group of cigarettes G, and has, at the top, an opening for picking up the cigarettes, and a lid 2B, which is hinged to the container 2A so that it is movable between a closed position and an open position.
  • the casing 2 has a parallelepiped shape, defining a front wall 21, a rear wall 211, two shorter side walls 2III, an upper wall 2IV and a lower wall 2V.
  • Figure 3 represents a blank for forming the casing 2 shown in Figure 2 .
  • flaps are indicated in the figures, with the reference numerals 109, 110, 111 and 112, respectively (the flaps of the same portion being indicated with the same reference number), starting from the edges of the portion 102.
  • portions 102 and 107 together define the front wall 21, the portions 104 and 105 the rear wall 211, and the flaps 109, 110, 111 and 112 define the side walls 2III.
  • the portions 103 and 106 instead define, respectively, the upper wall 2IV and the lower wall 2V of the casing 2.
  • the apparatus described herein is arranged to associate together a blank 100 with a group of cigarettes G, and to fold the blank around the group of cigarettes G so as to obtain a closed casing 2 containing the group of cigarettes G.
  • the apparatus described herein comprises, first of all, a forming wheel 20, which is rotatable about a rotation axis I, and is provided along its periphery with a plurality of seats 22, arranged to receive and maintain the blank 100 and the group of cigarettes G in a given reciprocal position.
  • the loading position C1 is at 270° - with reference to a theoretical trigonometric circumference centered on the axis I - and the unloading position C2 is at 180°.
  • the forming of the casing 2 therefore, envisages the folding of the other portions, and of the various flaps of the blank, against the group of cigarettes G.
  • This pack is oriented with the walls 21 and 211 orthogonal to the radial direction of the wheel.
  • the apparatus described herein comprises a pusher member 30, arranged to engage the wall 211 of the semi-finished pack that has reached the unloading position C2, and to push the pack out of the seat 22 and of the wheel 20, along a direction X coinciding with the radial direction of the wheel.
  • the pusher member 30 is constituted of a stem member mounted in a movable manner inside the forming wheel, along the direction X, and provided with a disc-like end portion 30A, facing outwardly from the wheel, and of an opposite end portion 30B, on which a toothed profile is provided, arranged to be engaged by means for actuating the pusher member.
  • a drying channel is provided for the glue that has previously been applied to the blank 100 to fix it in the closed configuration of the casing 2.
  • the apparatus described herein comprises a conveying section 50 for the packs, configured for connecting the forming wheel 20 with the mentioned drying channel (not illustrated).
  • the formed packs P2 accumulate within this section, creating a row of packs that extends along the direction X, and in which the packs are in mutual contact at their longer side walls.
  • the row of packs P2 advances in steps along the feeding direction X, in a manner synchronized with the movement of the pusher member 30 (in some embodiments, pushed by the same member 30, as will be seen below).
  • the two members 52B act on these walls by friction so as to exert an action on the packs P2 that is resistant to their movement along the direction X.
  • the two members 52B consist of two fixed plates that press on the walls 2III of the packs P2 to cause a given friction force.
  • the packs P2 advance with respect to the two plates 52B, pushed by the same pusher member 30.
  • the packs braked by the plates 52B exert a force on the wall 21 of the semi-finished pack which is opposite to the force exerted by the pusher member 30.
  • the two plates 52B can be adjustable in position to vary the force with which they press on the packs.
  • the optimal adjustment can be identified by means of a series of tests carried out on the apparatus in operation, during a preparation step of the packing installation.
  • the two belt members 53B are mounted on respective pulleys so as to extend along a closed loop path, and define respective opposed straight branches 53B', oriented along the feeding direction X.
  • the packs P2 engaged by the two belt members 53B advance along the direction X pushed by the pusher member 30.
  • the braking device 54 exerts an action resistant to the movement of the two branches 53B', which is transmitted to the same packs P2, through the friction force exerted by the belt members 53B' on the walls 2III of the packs.
  • the force exerted on the wall 2I of the semi-finished pack P1 therefore depends on the action of the braking device 54.
  • the braking device 54 can be an electromagnetic brake, which can be adjusted by the control unit of the installation. In this case as well, the optimal adjustment can be identified by means of tests carried out on the apparatus during operation.
  • the two belt members 53B move together with the packs and there is no relative motion between them.
  • the packs P2 are, however, moved by the same belt members 53B, which are operated by the drive system 56.
  • the movement of the belt members 53B is controlled on the basis of the actuation of the pusher member 30, so that the packs P2 only move after the semi-finished pack P1 has been brought against them, and the expected force between the packs P2 and the pack P1 has been determined, opposite to the force exerted by the pusher member 30.
  • the two belt members 53B are able to guarantee a predefined and precise positioning of the packs, for example, in order to carry out the rejection of defective packs through a window provided along the conveying section 50, and can also recover any empty spaces between adjacent packs.
  • the two blocks 58 each have a tapered edge 58A, facing the forming wheel 20, and a horizontal wall 58B which extends, without interruption, from the tapered edge 58A, and faces the wall 58B of the opposite block 58.
  • the distance between the two walls 58B is substantially equal to the width of the two walls 2I and 2II of the semi-finished pack P1 that is present in the unloading position C2.
  • the two walls 58B perform the function of keeping the flaps 109 and 112 in the just-reached closed condition.
  • the member 70 comprises a rod provided with a pair of teeth 72 protruding laterally and spaced apart from each other by a distance slightly less than the distance of the walls 58B of the two blocks 58 .
  • This member is controlled by a respective actuator (not illustrated) in a straight movement along a horizontal direction, between an inoperative position in which the two teeth 72 are kept outside the passage W, and the pack P1 can be inserted into this passage, and an operative position in which the two teeth 72 are placed within or overlapping the passage W (with respect to a view according to a plane orthogonal to the direction X), so as to engage the wall 211 of the pack P1, after this has been inserted into the passage W and has been released by the pusher member 30.
  • a pair of rods with teeth is provided, positioned symmetrically with respect to the passage W.
  • the apparatus described herein therefore, comprises a folding device configured to partially fold the flaps 109 and 112 towards the flaps 110 and 111.
  • the seat 22 is arranged with blocking elements configured to hold these flaps in the folded condition, to avoid their elastic return.
  • these elements are constituted by simple teeth 23 positioned in two diametrically opposite peripheral areas of the seat 22, on which the flaps 109, 112 are carried after the portion 102 of the blank 100 has been folded above the group of cigarettes G.
  • the blank 100 is received together with a group of cigarettes G inside a seat 22 of the forming wheel which is in the loading position C1.
  • the blank 100 is folded around the group of cigarettes G and is presented at the unloading position C2 in the configuration shown in Figure 4 .
  • the semifinished pack P1 thus obtained is pushed out of the seat 22 by the pusher member 30.
  • the semi-finished pack P1 is first brought into contact with the row of already formed packs P2, arranged in the conveying section 50.
  • the row of packs P2 exerts an action resistant to the movement of the pack P1, generating a predetermined force on the wall 21 thereof, opposite to that exerted on the wall 211 by the pusher member 30.
  • the pack P1 continues to advance, and its flaps 109, 112 encounter the edges 58A, which then fold these flaps against the flaps 110, 111.
  • the completed pack is inserted into the inlet passage W of the conveying section 50 and is held back by a possible retraction by the retaining device 70.
  • the pack passes through the section 50 in a stepwise motion and reaches the drying channel mentioned above.
  • the forming wheel 20, which in the illustrated example is mounted with its own vertically arranged rotation axis I, may also be mounted according to other arrangements, for example, with its rotation axis arranged horizontally.
  • outer casing 2 of the pack may also envisage other configurations, and its opposite walls which are engaged by the pusher 30 and the row of already formed packs P2, may not necessarily be its longer walls, and likewise its flaps that are bent by the blocks 58 are not necessarily the flaps of its shorter side walls.
