Definitions

  • the present invention relates to a movable box feeder feeder, more specifically intended to equip the sheet feed magazine with a processing machine, in particular for shaping, of corrugated cardboard boxes.
  • suction feeders are very widely used in the industry of corrugated cardboard boxes, and are described in numerous patents, such as for example French patents 1 343 103 and 1 568,091.
  • All these devices use one or more suction boxes, movable in the longitudinal direction, and the upper part of which is closed by a horizontal plate provided with holes, which transmits the vacuum to the sheet and thus allows, during at least part of the cycle of extraction, to grip the cardboard.
  • the feeder shown is a feeder very similar to that described in the French patent 1343103 (or US 3,226,108) cited above. It includes in particular a magazine 1, containing the stack 2 of sheets of corrugated cardboard to be extracted one by one from the underside of said stack, and delimited at the rear by a stop 3 adjustable according to the format of the sheets, and at the l 'before by the margin knife 4 defining with the margin table 5 a sufficient space to let pass a sheet of cardboard and only one.
  • the box 6 is connected to a vacuum source, not shown, by means of a pipe 8 and a distribution solenoid valve 9.
  • the solenoid valve 9 is controlled so as to that the vacuum is applied to the box 6 during its removal and advancement phase from the bottom sheet of the stack, and is released during the backward phase of said box.
  • the vacuum is applied to the bottom sheet through a horizontal plate 10 provided with holes 11 and the surface of which advantageously has the shape of sawtooth undulations clearly visible in FIG. 1.
  • an opening 13 of rectangular shape for example is cut in the plate 12 forming the upper periphery of the body of the box 6 so as to form a bottomless bowl whose edges form, with the upper face 14 of the periphery 12, an acute angle a, advantageously of the order of 45 degrees, as it appears clearly in FIGS. 1 and 2.
  • the edges of the suction plate 10 are cut so as to have a shape complementary to that of the edges 13 of the perimeter plate 12.
  • the plate 10 is intended to be screwed onto the body of the box 6 using the screws 16, fitting tightly into the bottomless bowl 13. Between the two is placed a flat and thin continuous seal 17 made of flexible material, virtually overhanging the edges of the bowl 13 and in extension therewith, as can be seen in the drawings, so as to form, with the suction plate 10, a suction cup with edges 26 raised upwards and forming an angle acute has with the horizontal.
  • the seal 17 is formed from a flat frame 18, shown in Figure 3, provided with a central opening at the four corners of which slots are cut at 45 degrees 20.
  • the Applicant has found that excellent results are obtained by using the sheet with belts, conventionally constituted of a woven nylon fabric on which a sheet of plastic material is glued, and mounting the seal 17 so that the fabric is located upwards, that is to say looks towards the stack 2, or towards the interior of the suction cup (10-17) of the invention.
  • the thickness of the suction plate 10 and that of the flexible frame 17 are determined relative to the periphery 12 so that the upper face 21 of the plate 10 is located above the upper face 14 of the periphery 12, with a difference in height at least equal to the thickness of the frame 17. In this way, the flexible frame 17 will never have to support the weight of the stack 2.
  • the operation of the device of the invention is as follows: when the vacuum is applied to a curved sheet 22, the leak is limited by the edges of the flexible frame 17, and the assembly (10-17) behaves like a hollow suction cup positively sucking the sheet 22 and straightening it at 23 while the frame 17 is folded over the periphery 12 as seen in FIG. 1.
  • the straightened sheet 23 can therefore be driven forward by the advance of the box 6, then be taken over by the driving rollers 7.
