  • Putting the separator fingers s 10 in the active separation position is carried out from the retracted waiting position in the grooves 14, by a compression spring 45 which is disposed between the carriage 28 and the carriage 24 and which biases the latter downstream at start of deployment of the extension of the jack 36.
  • the jack 36 When the predetermined count has been reached, the jack 36 is extended and, from the start of this stroke, the spring 45 acts in the manner of a trigger to release ins both the separating fingers 10 in the active position, this spring 45 pushing the carriage 24 and the separating fingers 10 downstream, overcoming the antagonistic action of the counterweight 42. As the articles 3 of the following batch are delivered on the table 4 behind the separating fingers 10, they exert an action directed downstream which overcomes the counterweight return force 42.

  • the upper strand 58 of the endless belt 55 carries a pawn 59 to which one end is hung a tension spring 60, the other end of which is attached to the carriage 24.
  • the heel 40 of its rod cooperates with the stop 41 secured to the carriage 24 and of the lower strand 56 to bring the carriage 24 backwards and simultaneously rotate the belt 55 anticlockwise ( Figure 8), against the action of the return spring 60.
  • the belt 52 is also driven in the same direction and the pin 50 carried by its strand lower 52 drives the auxiliary carriage 46 upstream and upward by tilting the separating fingers 10 to bring them into a position close to the tangent to the output drum 2.
  • the compression spring 45 slightly displaces the carriage 24, and consequently the stop 41 and the pin 57, downstream, by turning the belt 55 clockwise, this movement being further facilitated by the tension spring 60. As shown in solid lines in FIG.

  • FIGS. 1 to 3 another characteristic of the present invention is illustrated according to which means are provided for rotating 90 °, alternately in one direction and in the other, successive complete batches of articles which are deposited on the second conveyor 13, this rotation taking place in the plane of the articles, that is to say in a horizontal plane in the example considered, so that the excess thickness which may exist at one end of the batches, is located alternately on one side and the other at the outlet of the machine, for compensation of the excess thicknesses during the stacking of successive batches, for making up packages.
  • the articles 3 consist of bags or sachets which, at one end, for example the downstream end on the drum 2 and therefore the upstream end on the conveyor 13, have an increased thickness by a flap 3a for constituting and closing the bottom of the bags 3.
  • the accumulated extra thicknesses give the batches a trapezoid shape in vertical and longitudinal section. Thanks to the 90 ° rotation alternately on one side and the other, the extra thicknesses, at the exit of the machine, are located alternately to the left and to the right, the alternation being done from one batch to the other if machine 1 has only one production line, or in pairs of batches if machine 1 has two production lines.
  • the manufacturing machine 1 comprises two manufacturing lines, the rotation means therefore comprise two vertical tanks 89 without bottom which are located downstream of the conveyor 13 and which are capable of two movements: a rotational movement 90 ° in one direction or the other around a vertical axis, and a vertical upward or downward movement parallel to this axis.
  • Each bin for the batch receiving position shown in Figures 1 and 2, has a total opening upstream and has three vertical side walls 90.
  • Each tray is therefore in the form of a U open upstream.
  • the tanks 89 are fixedly suspended from a plate 91 secured to the lower end of a vertical rod 92 situated in the median longitudinal plane of the machine.
  • the vertical rod 92 is carried by a fixed bracket 93 which further supports means 94, for example an electric motor, for rotating the rod 92 by 90 ° in one direction or the other, and means 95, for example a double-acting cylinder, for vertically moving the rod 92.
  • the motor 94 and the cylinder 95 are controlled to cause the following sequence of operations, starting from the position in FIG. 1 for which the tanks 89 are in the low position of receipt of the two batches of articles.
  • the rod 92 rotates 90 ° in one direction or the other, in the opposite direction to the rotation applied to the previous pair of lots, so as to cause the two lots to be aligned according to the longitudinal direction of the machine.
  • the extra thicknesses of the lots which were initially upstream, are then, after this rotation, to the left or to the right.
  • the rod 92 is then raised to cause the tanks 89 to be raised, so as to free the tanks from the lots and allow them to be routed downstream. Then the tanks 89 are brought back to the initial low position, by lowering and rotating the rod 92 90 ° in the other direction.
  • the bottom of the tanks 89 is constituted by a movable surface 97 belonging to a conveyor 98 which, preferably, is distinct from conveyor 13 and which, also preferably, is constituted by a full endless belt.
  • the conveyor 98 is intermittently driven to move continuously until the end of the rotation of the trays, to stop at the end of this rotation at least until the end of the lifting of the trays, and to move again until the end of the rotation associated with the next cycle.
  • the conveyor 98 must be driven during the rotation of the tanks 89 so as to maintain in the corresponding tank that of the batches of articles which, during the rotation, moves downstream.
  • the transporter 98 At the end of the rotation and during the lifting of the bins, the transporter 98 must be stopped so as not to drive the lower part of the batches while their upper part still cooperates with the bins. When the tanks are fully raised, the transporter 98 is again actuated to drive the batches thus turned 90 ° downstream. The transporter 98 is followed, downstream, by another transporter 99 which ensures the evacuation of the batches with a view to their manual or automatic manipulation for the constitution of packages by stacking the batches.
  • FIGS. 13 to 15 various variants can be provided for the rotation of the batches of articles 3 transferred to the conveyor 13 by the drum 12.
  • the two batches of articles 3, aligned transversely are first offset transversely relative to the machine, while being brought into abutment against each other to then be routed downstream and be rotated by a single tray 89 ′.
  • the two batches of articles 3, aligned transversely are first separated from one another transversely, then they are each rotated by 90 ° by an individual tray 89 ⁇ .
  • one pair of batches out of two is offset transversely, as in FIG.
  • the invention allows the automatic handling of articles 3 at the outlet of the manufacturing machine 1, this handling being able to be done in particular thanks to the movement of the transfer drum 12 always in the same direction, by absorbing the production rate of machine 1 which can be very high; for example, this production rate can be 45,000 bags / hour, which represents, for batches of 100 bags, a cycle lasting 8 seconds for the separation means 9, the transfer drum 12 and the means of rotation, this duration being compatible with the structure given to the various means of the invention.
