  • the magnetic starter 246 has four contact pairs, which are normally open, of which the pair 1, 5 for self-excitation, whilst the magnetic starters 247 and 248 each have live contacts, of which the pair 1, 6 is normally closed and the other pairs normally open.
  • the contact pairs 2, 7 of said magnetic starters 247 and 248 are made of self-excitation contact pairs of the same magnetic starters 247 and 248.

  • the line above the neutral line which is shown by thinner dots shows the opening time of the related microswitch and the line below said neutral line sho-ws the closure time of the same microswitch.
  • FIG. 11 shows the manner in which the compartments 105, which are used for transporting the cigarettes, are formed and the manner in which the cigarettes themselves are arranged in said compartments.
  • Said compartments 105 are formed by a bottom 10'5a, a rear wall or face 105b and two sides 105C. The front and upper Sides are opened.
  • the cigarettes 253 are arranged in a parallel manner, with an axis which is essentially perpendicular to the rear face 105b, up to the moment in which they are completely full, as shown in FIG. 1l.
  • the ends of the sides 105C are slightly inclined towards the interior of the compartments, in their upper end portion and at least the rear Wall 105b is made totally or partially of magnetizable material.
  • the compartments 105, full of cigarettes, are brought, by hand or by mechanical actuation not shown, to the chains 62, 63, so as to bear with their bottom 105a on the series of idle rollers 194 and with their Wall 105b against the series of idle rollers 192 and 193 (see FIG. 9).
  • the device is then arranged (see FIG. 7) for an automatic cyclical working, by acting on the setup member 241, so as t bring into the closure position 1, 3 and 2, 5 the contacts of the microswitch 240
  • the pushbutton of the microswitch 251 is actuated, whereby its contacts 1, 2 are closed. Consequently, through the same microswitch 2'51, the magnetic starter 246 is excited, which thus closes its contacts and is kept self-excited, as far as its contact pairs 1, concerned, this self-excitation occurring through the microswitch 24 associated to the cyclical cam 17 for stopping the machine and the microswitch 252, normally closed, for a manual stopping of the machine itself.
  • the rotation of the shafts 50 and 53 in the direction of the arrows f2 and f3 respectively causes the front branch of the chains 62, ⁇ 63 and 64, 65 to advance in the direction of the arrows ;f and f1 respectively, conveying the compartments, which are replenished with cigarettes and which are carried by the chains 62, 63 towards the upperside and conveying the empty compartments which arrive at the chain 64, 65, downwards, as will be seen hereinafter.
  • the closure of said microswitch 26 causes the magnetic starter 248 to be excited through a pair of contacts 1, 6, which are normally closed, of the magnetic starter 247; the magnetic starter 248 remains in its self-excited condition as a consequence of the position of the pair of contacts 2, 7 and of the closed microswitch 210.
  • the closure of the pairs of contacts 3, 8; 4, 9 and 5, 10 of said magnetic starter 248 causes the electrical motor 196 to be started, which through the transmission belt 199 and pulley 200 drives into rotation the chain wheels 202, 203 and thus displaces the chains 204, 205 in the direction of the arrow f4.
  • the striking member 213, which is secured to the chains 204, 205 comes within the range of the actuation member 212 ⁇ of the microswitch 210, opening its contacts so as to brake the feeding of the magnetic starter 248, which, by its magnetic release, opens its contacts, stopping the electrical motor y1'96 and thus the movement of the same chains 204, 205, which have pushed the full compartment in said position 105B.
  • cam 40 causes the shaft 174 and thus the frame 176 to rotate in the direction of arrow f5, through the idle roller 165 of lever 166, the rod 170 and the radially extended sleeve 172, 173, whereby the compartment which is full of cigarettes is brought from the position 105B to the position 105C on the rotatable head 98 (see FIGS. 4, 5).
  • Said cam 40 is shaped so as to cause the frame -176 to rotate in a direction which is opposite to the arrow f5, rst bringing it in a position which is diagrammatically shown by the dotted line 2'54 corresponding to the maximum removal from the rotatable head 98, so as to allow said rotatable head 98 to effect a 180 rotation, as will be now seen, in fact, the rotation of the driving shaft 16 with the help of the gear 39 causes the gear 84 to rotate and thus the member 82 with the idle rollers 83, 83 and the annular groove 81 to also rotate, while said member 82 is axially displaced by the cam 37, 38 and the rotatable lever 76 so that the idle rollers 83, 83 are brought in the plane of the Maltese cross 86, which is made to -rotate along with one of said idle rollers 83 or 83', according to a pre-established rotation ratio between the gears 39 and 84.
  • the rotation of the Maltese cross 86 causes the chain wheel 89 secured to said cross 86 also to rotate and thus, by means of the chain 90 wound on the chain wheel 91 it causes the rotatable head 98 to eifect a 180 rotation, whereby the compartment which is full of cigarettes, is brought from the position C to the position 105D where the cigarettes are discharged in the hopper 233 beneath.
  • the semi-oval shaped members, 242, 242 and 243, 243', made of electrically conducting material are also made to rotate, whereby, as a consequence of said rotation, the semi-oval shaped members 242 and 243 are brought into contact with the wiping contacts 244 and 244 respectively.
  • the connection of the semi-oval shaped member 243 with the corresponding wiping contact 245 causes the electromagnets 139, 139' to be excited, this excitation occurring in timed relationship with the cyclical cam 20, which closes its associated microswitch 27; said electromagnet 139, 139" causes the members 113, 113' to spread apart or space away between each other and thus the opening of the discharge mouth of the compartment in position 105D, whereby the cigarettes are permitted to fall from said compartment in the hopper 233 beneath.
  • the electromagnets 139, 139 operate through respective mechanisms 120, 120'; 121, 121' and 127, 127', and against the resisting action of the associated springs 163, 163'.
  • connection of the semi-oval member 242 with the corresponding wiping Contact 244 causes the excitation of the electromagnet 143, 143', in timed relationship with the cyclical cam 21 which closes its associated micros-witch 28 (see FIGS. 7, 8); said electromagnet 143, 143 with the help of the relative associated two-arm members 151, 151' and against the resisting action of springs related thereto (which are not shown in the accompanying drawing) cause the plate 159, 159 to spread apart, thus freeing the empty compartment, whereby it can be removed, -as will be seen now, from the position 105C of the rotatable head 98, to be transferred in the position 105B of the rotatable frame 176.
  • the rotatable fname 176 is made to oscillate through the cam 40 and the relative mechanism which has been heretofore described, so as to be brought from its most removed position to the nearest position with respect to the rotatable head 98 and simultaneously, in timed relationship with the cyclical cam 22 closing its associated microswitch 29, the electromagnet 232 is excited, which comes into engagement with the empty compartment in its position 105C and brings it in the position 105B, as a consequence of the rotation whereby said frame returns in the position 105B, which rotation is transmitted by the action of said cam 40 (see FIGS. 7, 8).
  • a microswitch 25 is closed by means of the cyclical cam 18.
  • the closure of said microswitch 25 causes the magnetic starter 247 to become excited through the contact pair 1, 6 which is normally closed, of the magnetic starter 248, said magnetic starter 247 remaining self-excited as a consequence of the position of its pair of contacts 2, 7 and through the closed microswitch 209.
  • the closure of the contact pairs 3, 8; 4, 9 and 5, 10 of said magnetic starter 247 causes the electrical motor 196 to be put into motion, with a rotation direction which is opposite to that which has been described as a consequence of the excitation of the magnetic starter 248 and thus chains 204, 205 are put in motion in a direction which is opposite to the arrow f4.
  • Said magnetic starter 246 remains then self-excited, as already seen and hence, the driving shaft 16 is actuated, in a timed relationship with the cyclical cam 20, which opens its associated microswitch, by the dis-energization of the electromagnet 139, 139', which in this disenergizing condition allows the members 113, 113' to be brought again in their starting closure position under the action of the resisting springs 163, 163', said dri-ving shaft 16 causing as already seen, the rotatable head 98 to eiTect a new rotation, bringing the empty compartment from the position 105D to the position 105C and the full box, which, as already seen, arrived into the position 105C, from this latter position to the discharge position 105D, thus repeating the cyclical working operations, which have been already described.
