Definitions

  • This invention relates to a device capable of effecting the transfer of cigarettes gathered together in batches, each batch corresponding to a packet, from the line in which the formation of the batches occurs to the line in which the batches are conditioned into packets, in auto matic conditioning-wrapping-packing machines for cigarettes.
  • the apparatuses operate in manner such that the cigarettes are presented, during their conditioning, always arranged transversally with respect to the direction of adwance of the production cycle. Moreover, in the same machines, the batches of cigarettes designed to form the sin gle packets are constantly contained, protected and guided within surfaces or by holding means in general; this in order to maintain the batches, for the duration of the working, perfectly compact and already conformed, in the arrangement of the cigarettes which form said batches, as they will be packed.
  • the principal purpose of this invention is that of providing a device which can transfer batches of cigarettes from the line in which they are formed to the line of conditioning into packets in manner such that the batches, already conformed as they will be packed in packets, are constantly guided, accompanied, and never stressed, in particular manner of the axial direction, so as to guarantee the integrity of the cigarettes.
  • a further object of this invention is that of providing a device which can achieve the above-mentioned transfer at high speed, so as to be able to be easily adapted to conditioning machines having high production speeds of packets of cigarettes per unit time.
  • a device for the intermittent transfer of successive batches of cigarettes arranged in side-by-side relationship according to one or more parallel layers which is characterized in that it comprises a wheel or hub provided with radial princers, said pincers comprising a first jaw and a second jaw, mean capable of rotating said hub intermittently about its own shaft in phase with the presentation of the successive batches of cigarettes to the device, means capable of cyclically separating said jaws so as to pass during the rotation from a first opening position, in order to receive the batch of cigarettes, through a closing position for the transfer of said batch, to a sec ond opening position opposite in position to said first position, for the abandonment of said batch, the holding surface of at least one of said jaWs having a plurality of side-by-side cradles developing according to the shaft of said wheel, each of said cradles being shaped so as to receive longitudinally a cigarette, pusher means being provided for the introduction of the cigarettes inside said jaws, so that
  • FIG. 1 shows, part in view and part vertical longitudinal sections, according to different planes, a device according to the invention in its application to a machine for conditioning cigarettes into packets;
  • FIG. 2 shows the same device part in view and part in vertical cross-sections according to different planes.
  • the device according to the invention is described in its advantageous application to a conditioning machine, for packets of cigarettes. of the class described in my co-pending patent application No. 721,525, filed Apr. 15, 1968.
  • the machine comprises, in substance, a formation line of batches of cigarettes, which batches, once formed, are transferred towards successive conditioning stations advancing in step according to a direction perpendicular to the shaft of the cigarettes, that is transversally to themselves.
  • be primary motion shaft is indicated by reference numeral 1 and is supported by the rigid framework 111.
  • Said shaft nay coincide with the primary shaft of the conditioning nachine, or may be derived from this, or still may be inlependent.
  • the shaft 1 carries, rigid with it, two cog Wheels 2 and 3.
  • a shaft 4, perpendicular to said shaft 1 1nd supported at 5 and 6 by the framework 1a, has a :og wheel 7 rigidly mounted on it which meshes with the :og wheel 2. In this manner the motorization of the shaft 1 occurs.
  • the same shaft 4 carries moreover, rigid with it, 1 rhomboid cam, or revolving drum, 8.
  • the cam 8 prolided at the opposite ends with a pair of rollers 9 and [0, enters into engagement with the profile of a revolvng Maltese-cross member 11, entraining it in rotation with cyclically variable speed.
  • the Maltese cross wheel 11 is rigid with a shaft 12, parallel to the shaft 4, which projects from the rigid framework It: bearing at its end a wheel with four radial pincers generally indicated at 13.
  • the wheel 13 comprises a hub 14 secured on the shaft 12 and free to revolve with it.
  • the four pincers are symmetrically arranged m the said hub 14, that is, aligned and opposite two-by- :wo according to two perpendicular diameters.
  • Each incer comprises a first jaw 15, and a second jaw 16. Both the jaws are fork-shaped, so that, in practice, each pincer may be considered as being formed of the combinaion of two equal pincers, parallel and side-by-side.
  • the jaw 15 is secured by conventional means to the rub 14, being consequently rigid with it.
  • the jaw 16 is .nstead secured by conventional means to a spindle 17, which is supported so as to be free to revolve, in an ec- :entric position, by said hub 14. Said spindle 17 consequently develops parallelly to said shaft 12. It extends :owards the framework of the machine.
  • Each of the jaws l5 defines a holding surface plane 15a, while each of the aws 16 has a holding surface, corresponding and side-byside with the said surfaces 15a, having an undulating proile so as to define a succession of side-by-side cradles 16a.
  • each cradle has a cylindrical IIC shape whose radius is substantially equal to the radius )f the cross-section of a cigarette, and whose peripheral development is less than half the circumference of the lCCtlOIl of the cigarette. Therefore, as is known, the ciga- :ettes which are packaged in packets are arranged there side-by-side according to two or more parallel layers; :he batches of cigarettes which reach the device according :o the invention are already conformed to this arrangement.
  • the jaws 15 and 16 are parallel and spaced apart by a distance corresponding to the thickness of the batch of cigarettes (the :otal thickness of the parallel layers of cigarettes); while be number of cradles 16a will be equal to the number of :igarettes in side-by-side arrangement in one of the ex- :ernal layers of the group, in order to be able to house :hem.
  • a radial arm 18 is attached to the end of the spindle 17, :he end 19 of said radial arm being collar-shaped and forming a support for the shaft 20 of a revolving roller 21.
  • Said roller 21 engages with a disc cam 22 and, more prezisely, with an eccentric groove 23 formed in the surface of said cam.
  • Said cam 22 is mounted idle coaxially to the shaft 12. It is furthermore provided with a stirrup or arm 24 which extends radially and whose end forms the pivot for the end of a tie-rod 25 whose other end is articulated in 26 to a lever 27 with two arms 28 and 29.
  • Said lever 27 is pivoted about a shaft 30 and at the end of said arm 29 it carries an idle roller 31 which cooperates with a cam 32 with eccentric frontal groove 33.
  • the cam 32 is carried by a shaft 34 perpendicular to the main shaft 1 and is entrained in rotation, through a cogwheel 35 rigid with said shaft 34, by the wheel 3 carried by the main shaft 1.
  • the idle cam 22 is constrained, through the tie-rod 25 and the lever 27, to the movement followed by the roller 31 in its engagement with the cam 32. Consequently the cam 22 accomplishes an oscillating rotational movement about the shaft 12.
  • lever 36 In an intermediate section of the longitudinal development of the lever 36 is attached the common shaft of a pair of revolving rollers 39 and 40. This pair of rollers co-operate with a cam 41 rigid with the shaft 34 and provided with a double eccentric guide 42 and 43 for the rollers 39 and 40, respectively.
  • said lever 36 At its upper end, said lever 36 is pivoted, with the interposition of a link 44, at 45 to a parallelepiped protuberance 46. Situated on either side of said protuberance, and rigid with it, are two aligned sections of a horizontal rod-like member 47, which consequently develops parallelly to the shaft 1.
  • the lever 36 Due to the rotation of the shaft 34, and in consequence of the cam 41, the lever 36 performs an oscillating movement about its own pivot shaft 38, so that the rod-like member 47 is also similarly associated to a reciprocal to-and-fro movement in the direction of its own shaft.
  • the shaft 47 is constrained, in its longitudinal translational movement, by the engagement of the rollers 48, revolving about the shaft 49 rigid with the said protuberance 46, inside a longitudinal guide 50.
  • a protuberance 51 forming the support base of a first translator member 52, is rigidly attached to the shaft 47, while a further protuberance 51a, forming the support base of a second translator member 52a designed to cooperate with the member 52, is rigidly attached to the shaft 47a.
  • two vertical and preferably arched surfaces are defined, 53 and 53a respectively, parallel between each other and spaced apart by a section substantially corresponding to the length of the larger side of the bases of the packets of cigarettes.
  • the members 52 and 52a develop along two vertical parallel planes respectively which are contained inside two vertical parallel planes containing the branches of the forked jaws 15 and 16.
  • the profiling of the cams 41 and 41a is such that, as has been said, a certain displacement of phase exists between their movements. More particularly, the members 52 and 52a translate rigidly until arriving in the proximity of the end (for instance the right end looking at FIGURE 1) of their displacement.
  • the translator members 52 and 52a enter into the space contained between the branches of the said fork. More precisely the holding surfaces 53 and 53a are arranged in the range of the beginning and the end of the succession of the side-by-side arrangement of cradles of one of the pincers which is arranged horizontally and to the left of the support hub. In this position of the said pincer, a face presented by the support member 54 is practically aligned with the plane defined by the cradles of the relative jaw, inside the branches of the jaw. Furthermore, said member 54 has a longitudinal aperture in order to allow the insertion of the translator 52 between the jaws. The opposite limit switch of the rods 47 and 47a causes the two translator members 52 and 52a to translate (to the left in FIG. 1) until arriving to the first station of the line for conditioning the cigarettes into packets, where the batches of cigarettes are given up to other members.
  • the rotation, with uniform angular speed, of the main shaft 1 is transmitted, through the cog wheels 2 and 7, to the cam or revolving drum 8, which consequently also rotates with uniform motion about the shaft 4.
  • the periodic rotation coincides with the step of advancement of the single batches of cigarettes coming from the formation line of the batches.
  • the step may consequently accord with the time interval between the formation of two successive batches of cigarettes. More precisely, to each complete turn of the cam 8 there corresponds a rotation for half a turn of the cross 11, as well as the formation and advancement of two batches of cigarettes.
  • the wheel 13, being rigid with the shaft 12, is consequently also subjected to the same intermittent running, and similarly the four pincers forming said wheel.
  • each of the movable jaws 16 accomplishes, during the same rotation, oscillations about its own engaging spindle 17.
  • These oscillations are determined by the cam 22 which, through the engagement of its own eccentric groove 23 with the roller 21 carried by the radial arm 18 rigid with the spindle 17 causes the latter, during the revolution of the said cam about the shaft 12, to complete reciprocal oscillating rotations which are transformed into corresponding movements of the movable jaws 16 which are rigid with said spindle.
  • the cam 22 is arranged in such manner that at each complete rotation of the Wheel 13 the jaws 16 open and close twice, upon reaching the two opposite horizontal positions.
  • the translator members 52 and 52a effect their translational movement, rigidly with the shaft 47 and 47a, in synchronism with the rotation of the four pincers.
  • This translational movement is caused, as has been said, by the engagement of the levers 36 and 36a with the cams 41 and 41a.
  • the phase between the reciprocal movements of the members 52 and 52a and the rotation of the pincers is such that when a pair of opposite pincers is near to the horizontal position, correspondingly the members 52 and 52a, having arrived at the end of their journey (on right, in FIG. 1), they open slightly. Therefore the parallel and vertical surfaces 53 and 53:: are already in proximity of the position which will be assumed by the two ends of the cradled profile 22 when the relative pincer has reached the horizontal positions.
  • the batch is transversally inserted in the device, when a pincer is in a horizontal position and its jaws are spaced apart. More precisely, the batch of cigarettes must be already arranged for insertion in manner such that the cigarettes of the upper layer of the batch are exactly in correspondence, once inserted between the jaws, and the jaws are closed, with the side-by-side cradles of the right hand divergeable pincer.
  • the insertion of the cigarettes, transversally to the plane of the pincer wheel 13, is effected by a suitable pusher means (not shown) which push the batch of cigarettes at their tips until they are inserted inside the jaws which, in this position of the pincer, are spaced apart.
  • the cigarettes of the upper layer are exactly in correspondence with the cradles of the movable jaw. It must be noted that such transfer, transversal with respect to the jaws but axial with respect to the cigarettes, does not endanger the conservation or the integrity of the cigarettes. In fact, in order to effect the transfer the cigarettes are simply pushed without opposition, without therefore the exercise of stresses which may be harmful.
  • the movable jaw closes on the fixed jaw and the cigarettes are retained with a minimal effort of the jaws.
  • the device capable of effecting the transfer of batches of cigarettes perfectly achieves all the predetermined objects. More particularly, the transfer is effected in such manner as to safeguard the maximum integrity of the cigarettes and retain them constantly arranged in a compact batch forming the finished packet.
  • a transfer mechanism for said bundles comprising a rotary member having radially extending arms terminating in jaws, each of said jaws comprising a fixed element and an element displaceable parallel thereto, said jaws being adapted to grasp said bundle at said first station and to release said bundle at said second station, intermittent drive means for said rotary member including a Maltese Cross wheel attached thereto, a rotary cam actuating said wheel, cam means for separating said jaws at said second station, and a pair of pincers adapted to grasp the ends of said cigarettes in said bundle at said second station prior to separation of said jaws and means actuated after separation of said jaws for displacing said closed pincers in a direction radial to said jaws, thereby removing said bundle.
