Furthermore, the invention is directed to a sheet transport, which is in particular part of such a sheet-storage arrangement. The invention is also directed to a plant, in particular corrugated plant, with at least one such sheet storage arrangement.
  • Sheet deposit arrangements are well known in the art through prior public use. They are used for storing or stacking sheets in sheet stacks. A disadvantage of these sheet storage arrangements is that occasionally disturbances occur when stacking the sheets, which can lead to damage of at least one sheet or the sheet storage arrangement. A shutdown of the entire system can also be the result.
  • the invention has for its object to provide a sheet-storage arrangement that is particularly prone to failure or able to work extremely trouble-free.
  • a corresponding sheet transport or a corresponding system should also be delivered.

  • An endless drive belt 60 is guided around the drive shaft 58, the first guide roller 51 and the coupling roller 57 outside a frame wall 56.
  • the axis of rotation of the drive shaft 58 is parallel to the axis of rotation of the first guide roller 51.
  • the sheet extraction device 48 has a sheet feed region 61, which is present between the first guide roller 51 and the second guide roller 52.
  • the sheet feeding portion 61 thus extends between the lower conveyor belt 36 and the sheet stacking chamber 47. Er joins directly to the lower conveyor belt 36.
  • the webbing 49 extends straight from the lower conveyor belt 36 to the sheet stacking chamber 47 and slightly downward.
  • the sheet feed region 61 ends at the second guide roller 52.
  • the sheet drawing-out device 48 Downstream of the sheet feeding region 61 with respect to the circulating direction 50, the sheet drawing-out device 48 has a sheet stacking portion 69 provided between the second deflecting roller 52 and the third deflecting roller 53.
  • the sheet stacking portion 69 extends immediately adjacent to the sheet stacking chamber 47 along.
  • the webbing 49 extends straight down from the second deflecting roller 52.
  • the webbing 49 includes there against a vertical V at an angle w, which is between 1 ° and 8 °. It extends in the sheet stacking area 69 just over a length 1 which is between 6 cm and 40 cm, more preferably between 8 cm and 15 cm.
  • the sheet extracting means 48 Downstream of the sheet stacking area 69 with respect to the direction of rotation 50, the sheet extracting means 48 has a return area 62.
  • the return area 62 extends between the third guide roller 53 and the first guide roller 51.
  • the tension roller 54 and fourth guide roller 55 In the return region 62, the webbing 49 extends from the third guide roller 53 to the first guide roller 51 back. There, the webbing 49 extends at least partially opposite to the webbing 49 in the sheet-feed area 61st
  • the webbing 49 has an outwardly facing outer side 63 and an inner side 64 opposite the latter. From the outer side 63, there are several endless receiving recesses 65 of the webbing 49, which run parallel run to each other and are arranged equidistantly distributed over a direction perpendicular to the direction of rotation 50 extending width direction of the webbing 49.
  • the receiving recesses 65 are identical. They extend in the direction of rotation 50 of the webbing 49.
  • the receiving recesses 65 are bounded in the width direction by opposing flanks of the webbing 49. They have a constant width or width. In the area of the receiving recesses 65, the webbing 49 thus has a reduced, constant thickness.
  • the first sheet depositing device 39 has a bow retainer 66.
  • the bow retainer 66 comprises a cross member 67 which extends across the entire width of the webbing 49 and perpendicular to the direction of rotation 50 of the webbing 49.
  • the cross member 67 is disposed on the frame walls 56 and the frame 42. He runs below the third guide roller 53 and adjacent to this.
  • the cross member 67 extends horizontally.
  • a plurality of sheet retaining members 68 of the sheet retainer 66 jump upwardly and vertically, respectively.
  • the sheet retention members 68 are bar-shaped and extend down along the sheet stacking area 69. They are parallel to each other.
  • Each sheet retention member 68 has an upper free head end 70 which is formed by a horizontally extending head edge of the respective sheet retention member 68 and is fully received in the sheet receiving portion 65 in the sheet stacking portion 69.
  • the first sheet depositing device 39 has a pressure roller 71.
  • the pressure roller 71 extends horizontally and is freely rotatably mounted in a pivotable arm arrangement 72. It runs adjacent and parallel to the second circulation roller 52.
  • FIG. 2 shows then enters the stacked corrugated sheet 35 with its leading end 74 in the sheet stacking chamber 47 a.
  • the leading end 74 is pushed by the webbing 49 in the sheet stacking chamber 47 of the feed slot 73 on an already properly deposited corrugated sheet 35 and the stack bottom 46 away.
  • the leading end 74 of the corrugated sheet 35 thus leaves the webbing 49 after the feed gap 73.
  • a trailing end 75 of this corrugated sheet 35 is initially in the sheet stacking portion 69 on the webbing 49 on.
  • the trailing end 75 of the corrugated sheet 35 remains in contact with the webbing 49 even after passing through the feed nip 73. It enters the sheet stacking area 69 and is thus from the down there running Gurtband 49 targeted down to the already properly filed sheet 35 and the stack bottom 46 guided ( Fig. 3 ).
  • the trailing end 75 of the corrugated sheet 35 first reaches the head ends 70 of the sheet retention members 68.
  • the trailing end 75 of the corrugated paper sheet 35 slides downwardly on the sheet retention members 68 downwardly so forth continue down the corrugated sheet 35 ( Fig. 4 ). In this case, a relative movement between the corrugated sheet 35 and the sheet retention elements 68 occurs.
  • the trailing end 75 of the corrugated sheet 35 is preferably at least partially on the webbing 49 in the sheet stacking area 69 between the sheet retention elements 68 on.
  • the second sheet storage device 40 operates analogously.
