Definitions

  • the present invention relates to a device for separating double sockets. It also relates to a device for unstacking flat objects equipped with this separator.
  • This separator device can have the following drawbacks: It is desirable that the withdrawal of the separator does not take place, in particular in the case of a weakly rigid fold, in order to avoid excessive deformation of this fold, and this withdrawal which is of predetermined amplitude does not allow the handling of thick mail.
  • a device for unstacking flat objects comprising means for supplying flat objects, gripping means for flat objects, a device for separating double sockets according to the invention comprising retaining means, and transfer means, this unstacking device being characterized in that the separating device is placed between the gripping means and the transfer means, and in that the retaining means are controlled so that a force restraint is exercised each time an object is driven by the transfer means.
  • a destacking device 10 comprises a conveyor belt 14 on which are placed flat objects 9, for example folds, backed by a pallet 7 moving at the same speed as the belt 14, a supply magazine 13 in which folds 1-3 fall after leaving the conveyor belt 14, a gripping device 17, a double tap separator 20 and a transfer device 16.
  • the gripping device 17 comprises a perforated belt 15 moving around return pulleys .
  • a vacuum device 12, placed inside the belt, produces a vacuum zone opposite the supply magazine 13 and the double outlet separator 20.
  • the double outlet separator 20 comprises a first part 21 connected to the frame 18 of the unstacking device 10 by a first articulation 28 of axis substantially parallel to the axes of the return pulleys of the gripper 17, and a second part 19 connected to the first part 21 by a second articulation 29 with an axis substantially parallel to the axis of the first articulation 28.
  • This second part 19 supports a vacuum head 22 connected to a vacuum generating device (not shown in Figure 1).
  • Fm holding force
  • the separator 20 is activated by the front edge of an "object", whether this comprises a single fold or whether it consists of a double socket. For example, this activation can be commanded by occultation of a passage detector (not shown) located at the level of the separator 20. This is deactivated by the rear edge of this "object” by deactivation of another passage detector also not shown).
  • the separator 20 is in any case activated when the first passage detector is obscured.
  • this single fold is at the same time driven by the gripper 17 in the transfer device 16 to be immobilized there before its transfer to devices for sorting (not shown), and the separator 20 is deactivated as soon as the second passage detector is deactivated.
  • the separator of double sockets must be able to be retracted by flat objects with a weak force in order to avoid any risk of deterioration of fragile folds and blockage of the unstacking device 10. It is then necessary to provide an appropriate connection of the vacuum head 22 to a vacuum generator 34 so that the vacuum head 22 is not directly subjected to opposing forces due to the vacuum which it would be necessary to compensate. This connection must also follow the withdrawal movement due to thick folds and be of negligible stiffness. The solution of a separator sliding in the duct is not satisfactory because the force due to the vacuum would oppose that of the spring ensuring the maintenance of the separator against objects. An oscillatory movement would therefore inadvertently distance the mail separator. FIG.
  • the double outlet separator 30 comprises a first rigid conduit 37 having the shape of a bent tube and having a first part 31 the end of which acts as a vacuum head 22 and is in contact with a flat object 1 resting on a transfer support 35 and moving in a predetermined transfer direction Dt, and a second part 32 of axis substantially perpendicular to the first part 31 and integral with a structure 33 movable relative to a fixed support 38 in a direction of displacement Dm substantially parallel to the axis of the first part 31 of the rigid conduit 37.
  • the bent rigid conduit 37 is guided in a guide part 41 having a slot whose shape substantially follows the path of movement of the second part 32 of the rigid conduit 37, for example an arc of a circle.
  • the movable structure 33 integral with the rigid conduit 37 is equipped with a stop comprising for example a stop ball 46 in contact with a frame plane 48.
