Definitions

  • the mail is placed on edge on a carpet, against a pallet. Thanks to a simultaneous motorization of the conveyor and the pallet, the mail advances towards the gripper.
  • the carpet leads to an abrupt change in level, called in the following fall, near the mail gripper.
  • the supply magazine located between this chute and the gripper, is designed to receive folds or flat objects awaiting unstacking.
  • the gripper includes vacuum zones in front of which a perforated belt passes.
  • the mail When leaving the gripper, the mail passes in front of the vacuum zone of the double outlet separator, located on the other side of the mail. This body retains the mail which would be driven by friction by the previous mail, so as to let go only one mail at a time.
  • the mail is taken up in a transfer device which provides the interface between the unstacking device and a sorting device.
  • the object of the invention is to provide a transfer device capable of stopping a flat object of "any" thickness and in particular large format at the output of a unstacking device, to deliver this flat object on demand to a device sorting and whose arrangement contributes to minimizing the dispersion of downtime of flat objects inside it.
  • a device for transferring flat objects for transferring to sorting means flat objects at the outlet of a device for unstacking flat objects, characterized in that it comprises means for pinch a flat object initially located in a transfer plane, these means being arranged to move in a direction substantially perpendicular to the foreground and in that these pinch means are controlled to immobilize said flat object while awaiting authorization transfer to sorting means.
  • the pinching means comprise two pinching rollers comprising on their periphery a soft material and at least one of which is movable in a second plane of movement perpendicular to said first plane and, for each roller, a set of drive belts stretched around said roller and at least one return pulley disposed on either side of said roller.
  • the device for unstacking flat objects comprising means for supplying flat objects, gripping means, means for separating double sockets, and a device for transferring flat objects according to the invention is characterized in that the device for transferring flat objects comprises means for gripping a flat object previously driven by gripping means, these gripping means being controlled so that said flat object is transferred by said transfer device after reception a transfer authorization.
  • the unstacking device 10 comprises a movable belt 14 on which the mail is placed on edge, a supply store 13, a gripper for flat objects 16, a separator for double sockets 11 and a device for transferring flat objects 20 according to the invention.
  • the gripper 16 comprises a perforated belt 15 moving in front of a depression zone 12.
  • the flat objects placed on the mat 14 reach the edge of this mat, they are entrained in the supply store 13.
  • the first flat object is attracted by the gripper 16 due to the vacuum generated at the vacuum zone through the perforations of the belt 15.
  • the latter drives this flat object in a direction perpendicular to the direction of movement of the belt 14, towards the double tap separator 11.
  • This separator comprises a vacuum zone and has the function of retain a flat object that may have been frictionally driven by a previous flat object.
  • the flat object 1, placed on edge on a substantially horizontal plane 31 is then driven in a substantially vertical transfer plane P between two pinch rollers 21, 22 mounted opposite to the plane P.
  • Each pinch roller 21, 22 is arranged between two pulleys 23 and 24, respectively 25 and 35.
  • pulleys 23, 24, respectively 25, 35 are mounted in an alignment parallel to the plane P so that the pulleys 23 and 25, respectively 24 and 35 are made face with respect to the plane P and define a passage for a fold extending in the plane P.
  • Two belts 27, 30 engage the roller 21 and the pulleys 23 and 24 on two levels and two belts 28, 29 engage the roller 22 and pulleys 24 and 35 on two levels facing belts 27 and 30 respectively with respect to the plane P.
  • the pinch rollers 21, 22 preferably have on their periphery a crown made of soft material 21a, 22a which makes it possible to eliminate any risk of rebound of the mail and contributes to obtaining an almost immediate stop of a pinched ply between the two rollers.
  • These pinch rollers have a sufficiently large diameter to promote the penetration of thick folds between them.
  • the diameter of the rollers 21 and 22 is larger than that of the pulleys 23, 24, 25, 35 so that the belts 28, 29 only come into contact with the belts 27, 30 respectively at a pinch point located between the axes of the two rollers and indicated by the point of intersection between plane P and plane D in Figure 2.
  • the motorization of the transfer device 20 can be ensured either at the level of the pinch rollers 21, 22, or at the level of the pulleys 23, 24, 25, 35.
  • the two pinch rollers 21, 22 can move freely in a displacement plane D perpendicular to the plane of transfer of the folds.
  • only one of the pinch rollers is mobile, the other remaining fixed.
  • the movable roller (s) in the plane D disappears before a fold which enters the passage between the pulleys 24 and 35 and the belts 27 to 30 kept tensioned, act to bring the two rollers 21, 22 together one against the other in such a way as to pinch the fold.
  • the transfer device 20 is preferably placed as close as possible to the gripper 16 and has a transfer plane P which is preferably parallel to the gripping plane. Furthermore, the double tap separator 11 is preferably placed between the two belt levels 28, 29 and upstream of the pinch rollers 21, 22, with reference to FIG. 3.
  • the pinch rollers 21, 22 have the function of immobilizing each flat object while awaiting an authorization for transfer to sorting buckets (not shown). This transfer authorization can be issued by control and processing means associated with the sorting means. To maintain an acceptable flow, the pinch rollers are placed immediately after the double tap separator 11.
  • a transfer device therefore makes it possible to ensure an almost immediate stop of each fold taken into account whatever its thickness and its shape and therefore contributes to considerably reducing the dispersion generally observed in the stop of the folds.
