Definitions

  • the present invention relates to a device for stacking and picking sheets at the output of a rotary press comprising a stop device defining a stop surface capable of stopping the sheets in order to stack them along the stop surface, the stop surface having an upper limit, a separator movable between an open position away from a stack of sheets and a position engaged in the stack of sheets.
  • DE 10206056316 A1 discloses a sheet stacking and picking device comprising stops for stopping the sheets and forming a stack and a separator adapted to be disposed on the top of the stack to retain the following sheets arriving at the top of the stack, the stops being pivotable so as to clear a passage under the separator to allow the passage of a clamp capable of taking a sheet on the top of the stack.
  • An object of the invention is to provide a sheet stacking and picking device adapted for removing sheets at the output of a high speed press.
  • the invention proposes a stacking and sampling device of the aforementioned type, characterized in that the separator moves between the disengaged position and the engaged position while crossing the stop surface while passing under the upper limit.
  • the invention also relates to a rotary press capable of printing a strip of continuous material and separating it into individual sheets, comprising a sheet stacking device as described above.
  • the stacking and sampling device 2 represented on the Figures 1 to 4 is adapted to be disposed at the outlet of a press (not shown) providing separate independent sheets at high rate, in particular at the output of a rotary press exiting the sheets in the form of a sheet 4 in which the sheets overlap partially, and to form a stack 6 of leaves.
  • the sheet 4 of sheets arrives substantially horizontally in a longitudinal direction (arrow F1) and the sheets are stacked vertically to form the stack 6.
  • the stacking and sampling device 2 comprises a stop device 8 able to stop the sheets so as to form the stack 6.
  • the stop device 8 is arranged so that the sheets of the sheet 4 abut by their downstream edge (considering the displacement of the sheets along arrow F1 at the outlet of the press) against the stop device 8 and are stopped on the top of the pile 6.
  • the stopper 8 defines a substantially vertical stop surface 9 extending between a lower limit 10 and an upper limit 12.
  • the sheets are stacked on a support (not shown) which is provided with compensation means so that the height of the support gradually decreases as a function of the increasing weight of the stack 6.
  • the compensation means comprise, for example, springs supporting the support.
  • the stacking and sampling device 2 is suitable for allowing sheets to be taken from the top of the stack 6.
  • the stacking and sampling device 2 comprises a separator 14 insertable into the stack 6 so as to separate the stacked sheets from the following sheets.
  • the separator 14 is movable between an open position ( figure 1 ) in which it is disengaged from the stack 6 and an engaged position ( figure 2 ) in which it is engaged in the battery 6.
  • the separator 14 is arranged to engage just above the stack 6, in the sheet 4.
  • the separator 14 in the released position ( figure 1 ) is disposed on the side of the stop surface 9 opposite the battery 6. Between the disengaged position ( figure 1 ) and the engaged position ( figure 2 ), the separator 14 passes through the stop surface 9 by moving between the lower limit 10 and the upper limit 12, and in particular under the upper limit 12.
  • the separator 14 is movably mounted between its disengaged position and its position engaged by sliding perpendicular to the stacking direction, that is to say by substantially horizontal sliding (arrow F2 on the figure 1 ).
  • the separator 14 is fixed on a base 16 slidably mounted on at least one rod 18 fixed on the stop device 8 and extending horizontally from the stop device 8.
  • the displacement of the separator 14 is for example controlled manually.
  • the base 16 is provided with a handle 20 for pushing or pulling the separator 14 manually respectively in the stack 6 and out of the stack 6.
  • the separator 14 in the engaged position ( figure 2 ) is movable vertically between a low position ( figure 2 ) and a high position ( Figures 3 and 4 ).
  • the separator 14 In the low position, the separator 14 is movable between its unobstructed position ( figure 1 ) and its engaged position ( figure 2 ). Moving the separator 14 upwards from its low engaged position ( figure 2 ) to its upper engaged position ( Figures 3 and 4 ) makes it possible to disengage the top of the stack 6 to collect one or more sheets on top of the stack 6.
  • the stop device 8 is able to provide an opening under the separator 14 enabling a sheet to be taken from the top of the stack 6.
  • the stop device 8 comprises a lower part 22 movable between a raised position in which it defines at least partly the stop surface 9 for stopping the leaves, and a lowered position for defining a leaf removal opening under the separator 14.
  • the lower part 22 in the raised position ( figure 2 ) extends substantially vertically along the stack 6.
  • the lower portion 22 is rotatable about a horizontal axis A (arrow F4 on the figure 3 ) away from battery 6 to the lowered position ( figure 4 ) in which it extends substantially horizontally.
  • the lower portion 22 can oscillate according to the arrow T to stamp the sheets.
  • the lower part 22 and the separator 14 are arranged so that the separator 14 moves from its unobstructed position to its engaged position by passing above the lower part 22.
  • the stop device 8 is adapted to stop the following sheets arriving on top of the separator 14 in the engaged position high or low.
  • the stop device 8 comprises an upper portion 24 movable together with the separator 14 between the lower position in which the upper portion 24 at least partially defines the stop surface 9, and the upper position in which the upper part 24 stops the leaves arriving on the top of the separator 14. The following sheets are thus stacked on the separator 14.
  • the upper part 24 and the separator 14 are arranged so that the separator 14 moves from its unobstructed position to its engaged position by passing below the upper part 24.
  • the rods 18 are fixed on the upper part 24 so that the separator 14 moves vertically together with the upper part 24.
  • the sampling device 2 is initially in a stack configuration in which the lower part 22 is in the raised position and the separator 14 and the upper part 24 are in the low position, the separator 14 being in the disengaged position.
  • the separator 14 is moved to the engaged position ( figure 2 ). In doing so, the separator 14 passes between the lower part 22 and the upper part 24, passing above the lower part 22 and below the upper part 24, and engages over the stack 6. Then, the separator 14 and the upper part 24 are moved together in the high position ( figure 3 ). Then, the lower part 22 is moved to the lowered position ( figure 4 ).
  • the stacking and sampling device 2 is thus in a sampling configuration ( figure 4 ) in which it is possible to take one or more leaves on top of the stack 6 underneath the separator 14.
  • the removal of sheets is done manually or via a PLC.
  • the sheets retained by the separator 14 are spaced from the top sheets of the stack 6.
  • the front edges are spaced apart, the rear edges remaining in contact.
  • the stacking and sampling device 2 is brought back to the stacking configuration of the sheets on the stack 6 by an inverse sequence.
  • the battery 6 is thus closed.
  • the separator 14 is in the form of a plate provided with a front edge (considering the displacement of the separator from its disengaged position to its position engaged along the arrow F2) for insertion into the pile 6 in the form of a point 26 facilitating inserting the separator 14 into the stack 6.
  • the lower part 22 comprises a shaft 28 extending along the axis A and rotating about this axis A and several lower stops 30, 32 distributed along the shaft 28 being spaced apart.
  • the lower stops 30, 32 are fixed on the shaft 28.
  • the lower portion 22 is rotatable by rotation of the shaft 28 about its axis A.
  • the lower stops 30, 32 extend substantially vertically upwards from the shaft 28, and at least partly define the stop surface 9.
  • the lower stops 30, 32 extend substantially horizontally.
  • the shaft 28 is at a lower height than the separator 14 in the low position.
  • the lower portion 22 comprises two lower lateral stops 30.
  • the lower lateral stops 30 are long.
  • the separator 14 is located at a height less than that of the upper ends of the lower lateral abutments 30.
  • the lower lateral abutments 30 have a spacing sufficient to allow the passage of the separator 14 between them without interference between the lower lateral abutments 30 and the separator 14 .
  • the lower portion 22 comprises two intermediate lower stops 32.
  • the intermediate lower stops 32 are short.
  • the separator 14 is at a height greater than that of the upper ends of the lower intermediate stops 32. The separator 14 is therefore insertable into the stack 6 by passing above the intermediate lower stops 32 without interference between the intermediate lower stops 32 and the separator 14.
  • the upper portion 24 includes a transverse bar 34 and upper stops 36, 38 distributed along the cross bar 34 and extending downwardly from the crossbar 34.
  • the upper stops 36, 38 define at least partially the stop surface 9.
  • the crossbar 34 is located at a height greater than that of the separator 14, so that the separator 14 passes under the cross bar 34 between its disengaged position and its engaged position.
  • the upper portion 24 comprises two upper lateral stops 36.
  • the upper lateral stops 36 are long.
  • the separator 14 is at a height greater than that of the lower ends of the upper lateral stops 36.
  • the upper lateral stops 36 have between them a spacing sufficient to allow the passage of the separator 14 between them without interference between the upper lateral stops 36 and the separator 14.
  • the upper part 24 comprises two retractable stops 38 arranged to be located in a free state on the path of the separator 14 and to be retracted during the displacement of the separator 14 in the engaged position.
  • Each retractable abutment 38 is rotatably mounted about a substantially horizontal and longitudinal axis B, that is to say perpendicular to the plane of the stop surface 9.
  • the retractable stops 38 are spaced apart from one another with a spacing smaller than the width of the separator 14.
  • the retractable stops 38 are adapted to retract due to the displacement of the separator 14 in the engaged position. More specifically, the retractable stops 38 are separated by the separator 14 when the latter is moved into the engaged position.
  • the retractable stops 38 are mounted freely rotatable and biased down under the effect of their own weight.
  • Each retractable abutment 38 is arranged facing an intermediate lower abutment 32 and comes to the free state in contact with the upper free end of an intermediate lower abutment 32.
  • Each retractable abutment 38 is thus associated with an intermediate lower abutment 32 which defines a complementary abutment, the retractable abutment and the complementary abutment together forming a sheet-locking element extending over the entire height of the stop surface 9.
  • the lower intermediate stops 32 have inclined upper edges 39 oriented laterally outwardly.
  • the upper edges 39 are here inclined substantially at 45 °.
  • each retractable abutment 38 is in contact by a lateral edge with the upper edge 39 of the intermediate lower abutment 32.
  • the abutments retractable 38 are inclined with their lower ends more spaced than their upper ends rotatably mounted on the cross bar 34. The initial inclined position of the retractable stops 38 ensures the displacement in the desired direction when moving the separator 14 in the engaged position .
  • long stops (lower lateral stops 30 and upper lateral stops 36) extend vertically substantially over the entire height of the stop surface 9, between the lower limit 10 and the upper limit 12. As a variant, they extend only a portion of the height of the stop surface 9.
  • upper and lower stops overlap vertically to ensure continuity of the sheet locking elements over the entire height of the stop surface 9, between the lower limit 10 and the upper limit 12.
  • the transverse bar 34 is mounted vertically movable by means of two cylinders 40.
  • the separator 14 is vertically movable together with the transverse bar 34. To do this, the rods 18 are fixed to the transverse bar 34.
  • the separator 14 When moving the separator 14 from its unobstructed position ( figure 6 ) to its engaged position ( figure 7 ), the separator 14 comes into contact with the retractable stops 38 and spreads them allowing the passage of the separator 14 between the lower limit 10 and the upper limit 12 defined in particular between the transverse bar 34 and the shaft 28. Once the separator 14 inserted in the stack 6, the transverse bar 34 is displaced upwards, which causes the separator 14 to move in the up position ( figure 8 ). Then, the shaft 28 is pivoted about its axis A so as to retract the lower part 22 and to define an opening for taking a sheet from the top of the stack ( figure 9 ).
  • the insertion of the separator 14 through the stopping surface 9 defined by the stopping device 8 in the stacking configuration of the sheets makes it possible to insert the separator 14 between the sheets without interrupting the arrival of the sheets at a rate raised in the form of a sheet, and without damaging the leaves.
  • the stop device 8 serves to hold the stack 6, to stop the sheets arriving on the top of the separator 14 in the engaged position and to provide an opening for taking a sheet from the stack 6.
  • the stop surface defined by stops makes it possible to provide abutments that do not interfere with the separator 14 and / or stops interfering with the separator 14 to ensure effective blocking of the sheets while allowing the separator 14 to pass through the stop surface 9.
  • the stacking and sampling device 2 of Figures 1 to 9 comprises a lower portion 22 and an upper portion 24 between which the separator 14 passes.
  • the stacking device 2 comprises only a lower part 22, the separator 14 passing above it or through an opening, for example between stops spaced from it, or only an upper part 24, the separator passing below it through an opening of the upper part defined for example between stops spaced therefrom.
  • the stacking and sampling device 2 of the Figures 1 to 9 comprises upper retractable stops 38 on the upper part 24 and lower complementary stops 32 on the lower part 22.
  • at least one retractable stop is provided on a lower part.
  • the or each lower retractable stop can be biased upwards by return means such as a spring, and retractable downwards, for example by the action of the separator 14 moving in the engaged position.
  • return means such as a spring
  • Such a lower retractable stop is optional, associated with an upper complementary stop.
  • the separator 14 is mounted simply sliding on the upper part.
  • the separator 14 is further retractable in an inactive position away from the stack 6 when it is not necessary to use it.
  • the separator 14 is slidably mounted relative to an auxiliary transverse beam 41 which is rotatably mounted relative to the transverse bar 34 about a horizontal axis C and longitudinal. So, as illustrated on the figure 11 , the separator 14 can be retracted by rotation of the transverse beam 41 so as to raise it vertically and to separate the separator 14.
  • the separator 14 is slidably mounted by sliding its lateral edges 14A in two guides, and a slider 43 in a central slot 14B of the separator 14.
  • FIGS 12 to 14 illustrate another embodiment of a stacking and picking device 2 for placing the separator 14 in an inactive position.
  • the separator 14 in the disengaged position is pivotable about a horizontal and transverse axis D so as to orient the separator 14 vertically.
  • the separator 14 is slidably mounted on a base 42 rotatably mounted on the transverse bar 34 about the axis D.
  • the separator 14 is here slidably mounted on the base 42 by means of slots 44 formed in the separator 14 in which slide slides 46 integral with the base 42.

  • the separator 14 is configured to lift the sheets above the separator 14 due to its insertion into the stack of sheets.
  • the separator 14 has a substantially flat front portion 60 for inserting the separator 14 into a stack of sheets, extended rearwardly by a raised rear portion 62 inclined upwardly and rearwardly with respect to the front part 60.
  • the separator 14 When inserting the separator 14 into the stack of sheets, the latter is moved from front to back.
  • the front portion 60 fits first in the stack of sheets.
  • Further insertion of the separator 14 causes the rear portion 62 to be inserted into the stack of sheets. Because of the inclination of the rear portion 62, it follows that the sheets above the separator 14 are raised, in particular their edges located on the insertion side of the separator 14. It is then possible to take a or several leaves under the separator 14.
  • the separator 14 further comprises angled arms 64 for fixing the separator 14 extending rearwardly and upwardly from the front portion 60, on either side of the rear portion 62, to allow assembly separator 14 on a support.
  • the arms 64 are disengaged from the space behind and under the rear portion 62 to allow an operator to take sheets.
  • the separator 14 is disposed in a sampling device similar to any one of the Figures 1 to 14 , except that it is not necessary to provide means for lifting the separator 14 after insertion into the stack 6 of sheets.
  • the sampling procedure is simplified.
  • the separator 14 is moved from its unobstructed position ( figure 16 ) to its engaged position ( figure 17 ) then the lower part 22 is moved to the lowered position (arrow F4 on figure 17 ) so as to extract one or more sheets through the stop device 8 ( figure 18 ).
  • the stacking and sampling device 2 is suitable for being placed at the outlet of a rotary press 50 as illustrated on FIG. figure 19 .

  • an output rate of the sheets is 500 sheets, or 650 sheets per minute.
  • the rotary press 50 comprises a reeling unit 52 of a strip of continuous material (for example a strip of paper), at least one printing unit 54 making it possible to print the strip, and a cutting unit 56 making it possible to cut transversely the strip into individual sheets.
