Definitions

  • the present invention relates to a device "for supplying sheets to a processing machine, such as a feeder intended to equip a machine for shaping corrugated boxes.
  • suction feeders such as that described in United States patent No. 3226108, in which the sheet to be fed is made integral with a box on which a vacuum is applied cyclically, said box being also animated with a longitudinal back and forth movement in conjunction with a drive of the sheet by rollers placed directly downstream of this box.
  • These devices allow the sheets to pass under the margin knives located downstream of the feeder without the risk of jamming.
  • it happens with such devices in particular when treating thin, therefore light sheets, that these are put across, or "delta", the lateral edges remaining behind the upstream front of the sheet. , which gives a bad introduction.
  • delta the lateral edges remaining behind the upstream front of the sheet.
  • the feeder according to the invention allows, while not having the drawbacks of the previous devices, to have margin security under the knives inherent in suction feeders of the prior art while having perfect security in the register, whatever whatever the thickness of the carton.
  • It includes a flat and substantially horizontal margin table, a front stop or "margin knife” allowing one sheet to pass at a time, a rear pusher animated by a back and forth movement longitudinal and constituted by a ruler margin or a set of aligned claws, having in all cases a front heel-shaped machining to receive the rear edge of the sheet to be pushed, a rear stopper intended to support the rear of the pack of sheets and placed above of said pusher, and is characterized in that it further comprises one or more suction boxes situated (s) at the front and under said margin table and animated (s) with a longitudinal reciprocating movement by via a transmission linked to that moving said pusher so that their strokes are substantially in agreement during at least a first part of the forward stroke of said pusher corresponding to at least the longitudinal distance of
  • the box 12 and the rule 8 are kinematically linked to each other so that their respective longitudinal reciprocating strokes are conjugated according to the graph in Figure 2 where the stroke angle 0 is plotted on the abscissa, the stroke distance c on the ordinate, the curve relating to the box 12 being drawn in a strong line and that relating to the rule 8 in a thin line.
  • the solenoid valve is controlled. 13, for example by a conventional control with photocells sensitive to the longitudinal position of the box 12, so that vacuum is applied to the box. 12, during the first part C of the race corresponding to its advance, then be released thereafter.
  • the lever 18 communicates its oscillation movement on the one hand to the box 12 by 1 'intermediate a first set of connecting rods (19, 20), and secondly to rule 8 via a second set of connecting rods (21, 22), these sets of connecting rods being arranged, for example as in the figure, so as to communicate to the box 12 and to the rule 8 conjugate longitudinal movements in accordance with the graph of FIG. 2.
  • the pushing heel 9 can have a height greater than the thickness of a sheet, so that it is thus possible to have the maximum pushing efficiency even with thin sheets, especially without damaging the rear edge. Furthermore, in the case of a lower sheet 23 which would be tiled or curved, therefore unable to pass under the knife 3 which, with the prior devices, would cause a cardboard jam, the box 12 would then only suck air so that the back of the tiled sheet 23 would remain on the projection 11 and the introduction would be stopped without loss of material.
  • the device of the invention makes it possible to recover this defect, because the sheet will be readjusted in the next cycle on the heel of the rule, thus regaining its good margin position.
