Definitions

  • the present invention relates to a method of peeling sheets of paper stacked in reams of sheets by applying the ream against a curved surface to peel the sheets of this ream, in particular printed sheets, preferably valuable papers, as well as delivery devices. implementing this process.
  • patent DE-B 26 41 214 one describes such a device for taking off the reams of sheets.
  • This device is mounted in the path of the reams and comprises at least one pair of transport rollers forming between them a slot through which the reams of sheets pass, the width of this slot being less than the thickness of the ream, and the coat of at least one of these rollers being of elastic material.
  • buffer stocks are built up, generally in the form of oars or stacks, typically comprising 250, 500 or 1000 sheets.
  • the transfer of these reams of sheets from one processing device to the next is generally done on pallets with several reams.
  • Automatic palletizing, trolley guidance and automated storage systems are known in the state of the art.
  • One of the main difficulties in automating the chains of current devices for processing paper sheets therefore results from the handling of paper in the transfer of the reams from the pallet to a feeder while taking off the sheets, especially sheets of paper. value.
  • This operation is currently carried out by workers who peel the leaves of a row from each other, folding their edges, ventilating them and jogging them by hand, before feeding the feeder to the feed unit. printing or other processing device.
  • the object of the present invention is to allow the automation of the take-off operation.
  • This object is achieved by a method which is characterized in that the ream is applied against a curved surface to peel off the sheets of this ream by exerting pressure forces against the outer sheet of said ream along at least one line application parallel to the generators of the curved surface, that said application line is moved perpendicular to the generators of the curved surface over the entire length of the train and then beyond each of the edges of the sheets, releasing the sheets, l the intensity of said pressure forces remaining sufficient during their movement to maintain the leaves against the curved surface, the speed of said movement being adjusted so that the leaves released successively move away from the remaining curved leaves by restoring a flat train, and this formed train is jogged.
  • the stack of fallen leaves is shaped into a ream of irregular contours can be carried out by tilting the plate and jogging by a hydraulic system or by eccentric, or by any jogger known in the prior art.
  • the jogging table comprises a plate 1, composed of fixed elements 11, 12, and mobile elements 13, 14, 15, 16.
  • the mobile elements 13 and 14 can assume a position aligned with the elements 11, 12 and 15 to form a continuous support for a ream of sheets R, as shown in Figure 1, or can be moved below the fixed elements 11, 12 to leave an open area 17 ( Figures 2 and 3).
  • Below the center of the plate 1 is a retractable part in the shape of a piston 2 as well as, on either side of it, two rollers 61 and 62.
  • the perforated zone 17 is sufficient to allow passage to these rollers 61, 62 and to this piston 2 which can move in the vertical direction.
  • the movable elements 15, 16 form in their vertical position of the side walls of the tray.
  • the entire plate 1 can be tilted using a hydraulic cylinder 3 (FIG. 5) which lowers the fixed element 12.
  • a motor 5 is provided, fixed below the fixed element 11, and causing an unbalance 6 which vibrates the plate 1.
  • the take-off device 4 comprises a deformation cylinder 41, mounted in a frame 42 ( Figure 6) which carries, on one side of the cylinder 41, two jacks 44, 45 with their piston rods 48, 49 ( Figures 5 and 6) and, on the other side of the cylinder 41, two jacks 44 ', 45' with their piston rods 48 ', 49' ( Figure 6).
  • All these jacks are mounted on the frame 42 so as to rotate about the same axis, coaxial with the axis 43 of the cylinder 41, and are provided, for this purpose, with pins 46, 46 'respectively 47, 47' forming a part with the casings of the corresponding cylinders and being perpendicular to the axis of the corresponding rod 48, 48 ', respectively 49, 49'.
  • the pins 46 and 47 are housed in the frame 42, free to rotate, by rolling bearings 50, 51 and 52, the bearing 51 in the middle being common to the two jacks 44, 45.
  • the pins 46 'and 47' are housed in the bearing bearings 50 ', 51' and 52 ', the bearing 51' in the middle being common to the two jacks 44 'and 45'.
  • the cylinder rods 48, 48 ′ and 49, 49 ′ carry, according to FIGS. 5 and 6, take-off rollers 61 and 62 respectively which are free to rotate around their axes 63 and 64 and extend parallel to the axis 43 of the cylinder 41.
  • the take-off roller 61 is provided, on either side, with pins 65, 65 'housed so as to rotate in bearings provided in said rods 48 and 48'.
  • the take-off roller 62 is provided with pins, invisible in FIG. 6 (hidden by the pins 65, 65 '), these pins are housed in bearings of the rods 49, 49' of the jacks 45, 45 '.
  • two motors 55 and 56 respectively are provided, fixed on the upper part of the frame 42.
  • the pins 46, 46 'of the cylinders 44, 44' are extended by two pulleys 53, 53 'driven by the belts 54, 54' of the first motor 55.
  • the motor 55 can drive the jacks 44, 44 'around the axis 43 of the cylinder 41, driving the take-off roller 61 around of the cylinder 41 on which it rolls.
  • the movement of the motor 55 is transmitted to the belts 54, 54 'by means of two bevel gears 68 and a transmission shaft 67 at the ends of which pulleys 59, 59' receiving said belts are fixed. 54, 54 '.
  • the same drive system is provided for turning the jacks 45, 45 'around the axis 43 driving the take-off roller 62; this system comprises the motor 56, two belts 58, 58 'and two pulleys 57, 57' fixed on the pins 47, 47 '.
  • the movement of the motor 56 is transmitted to the belts 58, 58 'by two bevel gearboxes 70 and a transmission shaft 69 carrying the pulleys 60, 60' at its ends.
  • the rollers 61, 62 can be moved, on the one hand, in the radial direction relative to the cylinder 41 under the effect of the jacks 44, 44 ', respectively 45, 45' and, on the other hand , around the cylinder 41 in the angular direction on paths coaxial with the cylinder 41 and parallel to its surface.
  • These movements of the rollers around the cylinder 41 can be simultaneous, preferably symmetrical in the opposite direction, or independent of one another, the movements being carried out successively.
  • the elements 13 and 14 are lowered and separated from each other below the plate 1.
  • the piston 2 acting as a support, presses the oar R against the cylinder 41 serving as a guide for the mounting of the two rollers 61 and 62 ( Figure 2).
  • the rollers 61 and 62 then raise the train R, under the action of the jacks 44, 44 ', 45, 45' and press it against the cylinder 41 with a constant force.
  • the piston 2 is lowered ( Figure 3).
  • the plate 1 is lowered on one side using the jack 3 and the elements 13, 14 are closed; under the effect of the inclination and of a vibrating movement created by the unbalance 6 driven in rotation by the motor 5, the train R is jogged against the raised edge 15, that is to say made regular, as shown figure 5.
  • the train is then pushed using a pusher P '( Figure 6) in a direction F', perpendicular to the input direction F ( Figure 1), on a margin table to feed, for example, a printing machine.
  • the cylinder 41 shown in the figures is a cylinder of revolution, with a circumference slightly greater than the size of the sheets of paper. Any other shape of the directing curve (fraction of a circle, ellipse, parabola, etc.) of the cylindrical surface ensuring a difference in radii of curvature between the first and the last sheet of the ream can be used.
  • rollers 61 and 62 have been shown as solid rollers whose diameter is less than the thickness of the train; they can take other forms, for example, be provided with transverse grooves making it possible to breathe air tangentially to the sheets beginning to detach.
  • the rollers 61 and 62 can be actuated by screw jacks, etc .; their angular displacement can be effected by a multiple transmission motor or several independent motors around coaxial axes; they can be replaced by any mechanical device allowing a bar to roll or slide in a continuous movement on the edge of the curved train.
  • the pushers P, P ' can be replaced by any suitable manipulator arm or conveyor system.
