Definitions

  • the present invention relates to a device for unstacking flat objects, in particular mail folds, in particular open, of the advertising brochure or other type, comprising a path for driving a stack of objects on edge in abutment against a bank of jogging, unstacking means disposed in front of the free face of the first ply of the stack and consisting of a translation member at a speed V i perpendicular to the stack, a ply transfer means unstacked at a speed V 2 and a member anti double socket inserted between these two means.
  • Such known devices include, as unstacking means, a member for translating the folds, for example consisting of a rotary perforated drum in which a vacuum is created and causing the first fold at a speed Vi.
  • a transfer member is arranged downstream of this unstacking means, this transfer member being at a speed V 2 , identical to Vi.
  • a member intended to avoid double sockets is generally disposed between these two members, consisting of a brush or hinged flap arrangement.
  • the invention makes it possible to solve these problems of unstacking and double grips on open plies.
  • the double anti-gripping member is a retaining member acting on the other face of the fold, activated as soon as a fold is supported by the transfer means and whose retaining force is less than 1 'translation force of the transfer means, and the speed Vi of the translation member is less than the speed V 2 of the transfer means.
  • a double grip has an offset between the front edges of the two folds concerned.
  • the device thanks to its retaining member, retains the second fold in the event of a double grip and allows the normal passage of the depilated fold in the absence of a double grip.
  • the positioning, management and efficiency of the unstacking and retaining members ensure that the open folds are not damaged.
  • the management of the system guarantees that this actuation is not triggered until said front edge is not driven by said transfer member, in order to avoid the opening of a fold under the antagonistic effects of the member unstacking on the one hand, acting on the rear front of the fold, and the retaining member on the other hand, maintaining the front part of this fold.
  • the activation or deactivation of the unstacking means and of the retaining member is carried out by putting their respective vacuum heads into operation or stopping.
  • the latter represents a destacking device according to the invention in top view.
  • the depression of the member 4 is such that its retaining force is less than the translational force by pinching the transfer means 5.
  • the unstacking means 3 is arranged on one side of the plane of the jogging edge 2 and the retaining member 4 and the transfer means 5 on the other side.
  • Detectors 6, 7, 13 made up of photoelectric sensors are placed on the path of the unstacked fold.
  • the first detector 13 is located downstream of the jogging edge and close to it.
  • the second detector 7 is located further downstream but preferably upstream of the vacuum head 4.
  • the third detector 6 is the most downstream; it is located near the pinch point of the belts 10, 12 of the transfer means 5.
  • the unstacking means 3 drives the fold at speed V i to the pinch point of the transfer means 5 where it is set to speed V 2 .
  • Vi can be equal to 2 m / s and V 2 to 3.2 m / s.
  • the rear edge of the depilated fold disables the sensor 7, deactivating the head 4 and initializing a time delay at the end of which the head 9 is reactivated for unstacking the next fold.
  • the rear edge of the depilated fold disrupts the sensor 6, initializing a time delay at the end of which the head 4 is deactivated and the head 9 reactivated.
  • the second fold is therefore put back in gear. Its front edge obscures the sensor 6, which has the effect of reactivating the head 4 and deactivating the head 9.
  • the rear edge of the second fold will, depending on the condition of sensors 13 and 7, reactivate the head 9 and deactivation of the head 4 according to the possibilities described above and applied to the third fold.
  • a low vacuum chamber 11 is installed next to the unstacking means 3 upstream thereof.
