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 means for carrying a stack of folds on edge in abutment against a jogging edge, means for unstacking sequentially said folds, this unstacking means being disposed in front of the free face of the first fold of the stack and carrying out a translation of said fold at a speed V1 perpendicular to the stack under control of means for detecting the position of the fold, a transfer means to transfer the depilated fold at a speed V2, a double anti-gripping member interposed between these two destacking and transfer means, this double anti-gripping member being a vacuum head acting on the other face of the fold to retain it and having a retention force which is less than the translation force of the transfer means, the speed V1 of the translation member being less than l at speed V2 of the transfer means.
  • the object of the invention is to solve these problems of unstacking and double sockets on open pleats.
  • a double grip has an offset between the front edges of the two folds concerned.
  • the device thanks to three detectors makes it possible to control the double anti-grip member to retain the second fold in the event of a double grip and to allow the normal passage of the depilated fold in the absence of a double grip, which ensures that the open folds are not damaged .
  • the actuation of the double anti-socket member when the front edge of the fold is taken care of for the transfer member makes it possible 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 double anti-socket member on the other hand, maintaining the front part of this fold.
  • the fold in double grip if it exists, is stopped by the retaining member. There is no risk of it being damaged since it is not in contact with the unstacking member.
  • this fold is in turn engaged in the transfer member.
  • the invention also extends to a method of implementing such a unstacking device as defined in claims 6 and 7.
  • 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 V1 to the pinch point of the transfer means 5 where it is set to speed V2.
  • V1 can be equal to 2m / s and V2 to 3.2m / s.
  • 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 allow, depending on the state of the sensors 13 and 7, the reactivation of the head 9 and the 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.
