Definitions

  • the invention relates to a method and a device for collating printed sheets, in particular folded sheets and / or single sheets, according to the preamble of claims 1 and 8, respectively.
  • Collating machines are known with arranged in a row landing stations, each consisting of a magazine for receiving a folded sheet stack, from a trigger drum with a gripper mechanism for detecting and subtracting a respective bottom folded from the folded sheet pile folding sheet and from an intermediate support for temporary storage of the separated folding sheet.
  • the accumulation conveyor has a Falzbogenabzugsraum perpendicular oriented collection channel in which move a conveyor chain, which strip the individual folded sheets of the individual intermediate pads and gather together to form a book block on the collection channel.
  • DE 14 86 744 B is such a working with direction change collating machine shown. It also has reciprocating intermediate tables, whereby the individual folded sheets are pre-accelerated for the entrainment by the carriers of the collecting conveyor.
  • a disadvantage of the known separating devices is that the weight of the folded sheet stack rests on the respectively lowermost folding sheet with the consequence of corresponding frictional forces between the lowermost sheet to be drawn off and the following folded sheet of the stack. This can lead to markings on sensitive surfaces. In addition, there is a risk that the following folded sheet is entrained. To minimize the frictional forces stack lifter and Blas Kunststoffdüsen are used, with the blowing air an air cushion between the lowermost and the following folded sheet is to be generated. This often succeeds only partially, since the introduced blast air escapes from the stack according to the principle of least resistance.
  • the present invention has for its object to provide a method and apparatus for collating sheets, especially folded sheets and / or single sheets, according to the preamble of claim 1 and claim 8, which allow a reliable and gentle product gentle separation of the sheet.
  • the idea of the invention lies in the fact that the printed sheet stack is carried in the magazine by an air cushion, whereby the air cushion immediately forms between the lowest printed sheet and the remainder stack with the lifting off of the respectively lowest printed sheet without the air cushion collapsing.
  • the stack is also carried by the air cushion at a constant level when the lowermost signature is lifted, while the lifted signature is carried away from the stack within the air cushion and finally completely separated from the stack by the air cushion, thereby allowing a frictionless exit port.
  • the air cushion is generated by a laterally introduced below the stack blowing air flow. It is expedient if the lowermost sheet in the area of the blast air flow is lifted off the stack. As soon as the blast air flow reaches between the partially lifted printed sheet and the remaining stack, the air cushion forms there, namely, the sheet being instantaneously completely separated from the stack.
  • a preferred embodiment of the method according to the invention provides that the printed sheet completely separated from the stack is pressed by the pressure of the air cushion onto a conveying surface presenting a support surface, whereby a slip-poor acceleration to a high exporting speed is made possible.
  • a preferred embodiment of the invention provides that by venting the air cushion, a certain altitude of the stack bottom side is maintained. In conjunction with the amount of air supplied to the air cushion results from the venting a simple pressure control for the air cushion.
  • the stack is supported at an angle inclined from the air cushion, wherein an outer side of the stack is supported on a wall weight relieving.
  • a preferred embodiment of the invention provides that the printed sheet is conveyed away parallel to the conveying direction of the collecting conveyor and fed to the collecting conveyor substantially at a synchronous conveying speed. The sheets separated from the magazine are fed to the collecting conveyor without change of direction.
  • the figures show a gathering machine designated as a whole by 1, which is essentially formed by a collecting conveyor 10 and a plurality of laying stations 15 arranged in series above it, wherein only a single landing station is shown in the figures for reasons of illustration.
  • a single folded sheet 3 is removed from a stack 4 same folded sheet and fed to the accumulation conveyor 10 for stack formation in each case.
  • the collecting conveyor 10 is formed of a conveying channel 11, with an inclined channel bottom 11 b and a perpendicular channel wall 11 a, and one in (collecting) conveying direction F with a continuous conveying speed v S driven conveyor chain 12 with arranged in the same mutual distance , the book block 2 formed in the conveyor channel 11 in front of her pushing drivers 13, wherein the back 3 a of the book block or the signatures 3 abuts against the vertical channel wall 11 a.
  • the inventively designed landing station 15 has a magazine 20 with lateral magazine boundaries 21 a to d and with a pelvis 23 as a lower part in which by feeding a Blas Kunststoffstroms V a Falzbogenstapel 4 supporting air cushion LP is formed.
  • the basin 23 is formed by a front and a rear side wall 24 a and b, a left and a right side wall 25 and 26 and a bottom 27th
  • the magazine 20 with the pelvis 23 is arranged inclined at an angle such that the folded sheets create in the folded sheet stack 4 with her back 3 a to the right side wall 26.
  • the right side wall 26 has up to the upper magazine area extending conveyor belt 22 with profiled wings, which provide for a further weight relief and at the same time serve to Nachellen the folded sheet stack 4.
  • the Blas Kunststoffstrom V is introduced with a arranged in the right side wall 26, connected to a Blas Kunststoffska not shown Blas Kunststoffdüse 29 into the basin 23 and escapes when resting a folded sheet stack 4 mainly through vents 25 a in the opposite side wall 25. It creates an air cushion LP with a pressure P to the atmosphere, which is able to carry the folding sheet stack 4 according to the hovercraft principle.
  • the Tragieri is in the area of the vents 25 a, which allow easy pressure control: with the resting of the folded sheet stack 4 on the air cushion LP, the vents 25 a partially covered, whereby their effective passage cross-section for discharging the air cushion LP vents Operablas Kunststoffströme V i reduced is.
  • the air cushion LP raises the folded sheet stack 4, which leads to an increase in the passage cross section with the result of a corresponding pressure drop in the air cushion LP until the pressure P is again in equilibrium with the stack weight of the folded sheet stack 4 to be supported.
  • the effective passage cross-section is reduced so that an air cushion LP adjusts with a correspondingly higher pressure P.
  • the separating device for separating the respective lowermost folding sheet 3 from the magazine 20 has at least one nipple 30 which acts clockwise in the rear, near-edge edge region on the signatures 3 and lifts the signatures 3 in the region of the Blas Kunststoffdüse 29 from the folded sheet stack 4 down.
  • the Blas Kunststoffstrom V passes into the space between the raised and the following folding sheet, whereby the air cushion LP is formed in the space and the bottom most folded sheet 3 is completely separated from the folded sheet stack 4 instantly.
  • Clockwise moving stack lifter 32 in the right side wall 26 thereby support the remaining stack and ensure that the folded sheet stack 4 is still maintained at the constant Tragieri.
  • the completely separated from the folded sheet stack 4 signatures 3 is pressed by the pressure P of the air cushion LP lying flat on the bottom 27 of the basin 23 and pressed in particular on a 27 running parallel to the collecting conveyor 10, continuously driven conveyor belt 31 in the ground, creating a slip acceleration on a high, approximately at the (collecting) conveying speed v S lying exporting speed v H is made possible.
  • the signatures 3 is transported absolutely frictionless to the folded sheet stack 4 through an exit gap 28 in the front side wall 24 a, wherein the further transport outside of the magazine 20 is ensured by pressure rollers 34 which act on the out of the magazine 20 reaching out conveyor belt 31.
  • the transported out folded sheet 3 is transported from a conveyor belt 10 inclined to the accumulation conveyor 35, formed from a lower and upper conveyor belt 36, 37 and a support plate 38 to the collecting conveyor 10 and transported at the conveying speed v H in front of the respective driver 13.
  • the individual folded sheet 3 is thus transported without change of direction from the magazine 20 and supplied with almost synchronous conveying speed v H the collecting conveyor 10 for stack formation.
