本発明の課題は要求に応じてほとんど残すことなく欠陥枚葉紙を主紙流から除去できる、積紙上へ枚葉紙を搬送する装置を提供することである。   An object of the present invention is to provide an apparatus for transporting a sheet of paper onto a stack of paper that can remove defective sheets from the main paper stream with very little on demand.

本発明の課題は、請求項1の特徴を有する装置によって解決された。   The object of the invention has been solved by a device having the features of claim 1.

有利な構成は従属請求項に記載されている。   Advantageous configurations are set forth in the dependent claims.

本発明によれば枚葉紙の搬送路において、副紙流に裁断装置が配置されている。欠陥紙は主紙流から排出されかつ自動的に裁断装置に引渡される。裁断された枚葉紙材料は吸出しにより除去されることができる。   According to the present invention, the cutting device is arranged in the sub-sheet flow in the sheet conveyance path. The defective paper is discharged from the main paper stream and automatically delivered to the cutting device. The cut sheet material can be removed by suction.

本発明はチェーンに固定されたグリッパにおいて枚葉紙が前縁もしくは後縁にて把持される排紙部を備えた枚葉印刷機において有利な形式で使用可能である。チェーンは変向ローラを介して案内されかつ軌道に沿って積紙の上を導かれる。作業員によって又は検出器を用いて、反故紙が印刷されたことが認識されると、チェーン軌道の下側軌道区分におけるグリッパは積紙の上の領域では開放されない。欠陥紙は変向ローラを介して先へ導かれ、副紙流にて裁断装置に供給される。裁断装置が切刃を有する2つの逆向きに回転するシリンダから成っていると、欠陥紙は一方のシリンダに固定されたグリッパシステムにより引取られる。この場合には吸込み装置は上側の軌道区分の上側に設けられる。   The present invention can be used in an advantageous manner in a sheet-fed printing press provided with a paper discharge unit in which a sheet is gripped by a leading edge or a trailing edge in a gripper fixed to a chain. The chain is guided through turning rollers and guided over the stack along the track. When it is recognized by the operator or using the detector that the waste paper has been printed, the gripper in the lower track section of the chain track is not released in the area above the stack. The defective paper is guided to the front through the turning roller and is supplied to the cutting device in the sub-paper flow. If the cutting device consists of two counter-rotating cylinders with cutting edges, the defective paper is taken up by a gripper system fixed to one of the cylinders. In this case, the suction device is provided above the upper track segment.

以下、図示の実施例に基づき本発明を説明する。   Hereinafter, the present invention will be described based on illustrated embodiments.

図1には枚葉印刷機の排紙装置における積紙2の上へ枚葉紙1を搬送する装置が概略的に示されている。排紙装置はチェーン3に固定されたグリッパ4から8までを有するチェーングリッパシステムを有している。チェーン3は変向ドラム9に巻掛けられかつ軌道に沿って案内されている。チェーングリッパシステムの下側のチェーン区分は部分領域10では積紙2の上面に対しほぼ平行に延在している。枚葉印刷機の最後の印刷部から搬送されて来る枚葉紙の前縁は前縁グリッパ4,6,8に把持され、枚葉紙の後縁は後縁グリッパ5,7に把持されている。前縁グリッパ4,6,8と後縁グリッパ5,7は同期的に循環する。グリッパ4から8まではそれぞれグリッパブリッジの上に位置している。グリッパ4から8までの開閉はそれぞれグリッパ軸10から15で行われる。グリッパ軸10から15はそれぞれローラレバー伝動装置16から20と連結されている。   FIG. 1 schematically shows an apparatus for transporting a sheet 1 onto a stack 2 in a sheet discharge device of a sheet-fed printing machine. The paper discharge device has a chain gripper system having grippers 4 to 8 fixed to the chain 3. The chain 3 is wound around a turning drum 9 and guided along a track. The lower chain section of the chain gripper system extends substantially parallel to the upper surface of the stack 2 in the partial region 10. The leading edge of the sheet transported from the last printing section of the sheet-fed printing machine is gripped by the leading edge grippers 4, 6 and 8, and the trailing edge of the sheet is gripped by the trailing edge grippers 5 and 7. Yes. The leading edge grippers 4, 6, 8 and the trailing edge grippers 5, 7 circulate synchronously. The grippers 4 to 8 are respectively located on the gripper bridge. The grippers 4 to 8 are opened and closed by gripper shafts 10 to 15, respectively. The gripper shafts 10 to 15 are connected to roller lever transmissions 16 to 20, respectively.

主紙流における積紙2の上に排紙するためには枚葉紙1は前縁グリッパ4,6,8と後縁グリッパ5,7で積紙2の上へ搬送される。積紙2の上側ではローラレバー伝動装置16から20のローラが制御カム21,22の上を走行する。その際各グリッパ4から8は開放される。主紙流における枚葉紙1は積紙2の上面の上へ落下する。積紙2は生産の進行に相応して下降させられるので落下高さはほぼコンスタントである。   In order to discharge paper onto the stacked paper 2 in the main paper flow, the sheet 1 is conveyed onto the stacked paper 2 by the leading edge grippers 4, 6, 8 and the trailing edge grippers 5, 7. On the upper side of the stack 2, the rollers of the roller lever transmissions 16 to 20 run on the control cams 21 and 22. At this time, the grippers 4 to 8 are opened. The sheet 1 in the main paper flow falls onto the upper surface of the stack 2. Since the stack 2 is lowered according to the progress of production, the drop height is almost constant.

欠陥枚葉23が発生すると、枚葉印刷機の制御装置から信号が発せられ、この信号は主紙流における制御カム21,22をローラレバー伝動装置16から20までのローラ軌道の外にもたらす。ローラが制御カム21,22の上を転動しないので、主紙流にてグリッパ4から8は開放させられない。欠陥枚葉紙23はグリッパ5,6により副紙流にて引続き搬送され、変向ドラム9を介し、チェーン23の上側のチェーン区分に達する。チェーン3の軌道の上側と下側とにおいては上側のチェーン区分にて前縁グリッパ4,6,8と後縁グリッパ5,7とのために別の制御カム24,25が配置されている。欠陥枚葉紙23,24を把持する前縁グリッパ4,6,8のローラが制御カム24に乗り上げると、該当する前縁グリッパ4,6,8が開放される。この場合、欠陥枚葉紙23,24の前縁はシュレッダローラ26の上に配置されたグリッパブリッジのグリッパ25により把持される。グリッパ25を開閉するためには不動のカム27が設けられている。シュレッダローラ26は第2のシュレッダローラ28と協働する。両方のシュレッダローラ28は同期的に回転し、チェーン3の送り速度に相応する周速度を有している。シュレッダローラ26,28はその軸29,30で互いに平行に支承されている。軸30は鉛直方向で軸29よりもいくらか高く位置しているので、グリッパ4,8は衝突することなくシュレッダローラ28を通過する。両方のシュレッダローラ26,28は互いに協働する刃を有している。欠陥枚葉紙がシュレッダローラ26,28の間のギャップに達すると、グリッパ25が開放される。枚葉紙23,24はストリップ33に裁断され、ストリップ33は吸出し装置35の構成部分であるホッパ34に達する。後縁グリッパ5,7のためのローラレバー伝動装置のローラが制御カム25に乗り上げると欠陥枚葉紙23,24の後縁が解放される。枚葉紙の残りはシュレッダローラ26,28でギャップ32内へ搬送され、引続き裁断される。吸出し装置35は裁断された枚葉紙が残らず枚葉印刷機から除去されるために役立つ。   When a defective sheet 23 is generated, a signal is issued from the control device of the sheet printing machine, and this signal brings the control cams 21 and 22 in the main paper flow out of the roller track from the roller lever transmissions 16 to 20. Since the rollers do not roll on the control cams 21 and 22, the grippers 4 to 8 cannot be opened by the main paper flow. The defective sheet 23 is continuously conveyed in the sub-sheet flow by the grippers 5 and 6 and reaches the upper chain section of the chain 23 via the turning drum 9. On the upper and lower sides of the track of the chain 3, separate control cams 24, 25 are arranged for the leading edge grippers 4, 6, 8 and the trailing edge grippers 5, 7 in the upper chain section. When the rollers of the leading edge grippers 4, 6, and 8 that grip the defective sheets 23 and 24 run on the control cam 24, the corresponding leading edge grippers 4, 6, and 8 are released. In this case, the leading edges of the defective sheets 23 and 24 are gripped by the gripper 25 of the gripper bridge disposed on the shredder roller 26. In order to open and close the gripper 25, an immovable cam 27 is provided. The shredder roller 26 cooperates with the second shredder roller 28. Both shredder rollers 28 rotate synchronously and have a peripheral speed corresponding to the feed speed of the chain 3. The shredder rollers 26 and 28 are supported parallel to each other by their shafts 29 and 30. Since the shaft 30 is positioned somewhat higher than the shaft 29 in the vertical direction, the grippers 4 and 8 pass through the shredder roller 28 without colliding. Both shredder rollers 26, 28 have blades that cooperate with each other. When the defective sheet reaches the gap between the shredder rollers 26, 28, the gripper 25 is opened. The sheets 23 and 24 are cut into strips 33, and the strips 33 reach a hopper 34 that is a constituent part of the suction device 35. When the rollers of the roller lever transmission for the trailing edge grippers 5 and 7 run on the control cam 25, the trailing edges of the defective sheets 23 and 24 are released. The remainder of the sheet is conveyed into the gap 32 by the shredder rollers 26 and 28 and is continuously cut. The suction device 35 is useful for removing all the cut sheets from the sheet press.

図2にはシュレッダローラ26,28が詳細に示されている。シュレッダローラ26,28はピン36から39を有し、該ピン36から39でシュレッダローラ26,28は枚葉印刷機の排紙装置のフレーム40に支承されている。シュレッダローラ26,28の外套面にはそれぞれ1つの方形の切刃プロフィール41,42が構成されている。切刃プロフィール41,42の溝とウエブ44は交互に係合しあっている。溝43もしくはウエブ44の側面45,46は切断面を形成している。シュレッダローラ26のグリッパは回転可能に支承されたグリッパ軸47に配置されている。グリッパ軸47はローラ49を有するローラレバー48と連結されている。ローラ49はカム27(図1)の上を転動する。グリッパ25の幅はウエブ44の幅よりもわずかである。各グリッパ25にはシュレッダローラ28にて切欠き50が配属されている。この切欠き50内へグリッパ25がシュレッダローラ26,28の回転に際して侵入する。1つの切欠き50の幅は溝43の幅よりも狭く構成されている。   FIG. 2 shows the shredder rollers 26 and 28 in detail. The shredder rollers 26 and 28 have pins 36 to 39, and the shredder rollers 26 and 28 are supported by the frame 40 of the paper discharge device of the sheet-fed printing machine. One rectangular cutting edge profile 41, 42 is formed on the outer surface of the shredder rollers 26, 28, respectively. The grooves of the cutting edge profiles 41 and 42 and the web 44 are alternately engaged with each other. The side surfaces 45 and 46 of the groove 43 or the web 44 form a cut surface. The gripper of the shredder roller 26 is disposed on a gripper shaft 47 that is rotatably supported. The gripper shaft 47 is connected to a roller lever 48 having a roller 49. The roller 49 rolls on the cam 27 (FIG. 1). The width of the gripper 25 is slightly smaller than the width of the web 44. A notch 50 is assigned to each gripper 25 by a shredder roller 28. The gripper 25 enters the notch 50 when the shredder rollers 26 and 28 rotate. The width of one notch 50 is narrower than the width of the groove 43.

図3には枚葉印刷機のチェーン排紙装置の下側のチェーン区分に欠陥枚葉紙51の放出装置と裁断装置が配置されている本発明の変化実施例が示されている。積紙への搬送路には2つのシュレッダローラ52,53が配置されている。シュレッダローラ52,53の軸54,55は互いに平行にかつ鉛直方向で互いにずらされて位置している。欠陥枚葉紙51は積紙の上に置かれるのではなく、前縁グリッパ56で引続き搬送される。搬送路にてシュレッダローラ52の前には制御カム57が配置されている。この制御カム57はグリッパ56を開放する。ブロー条片58で枚葉紙51の前縁は、前縁が変向ローラ60,61に巻掛けられかつシュレッダローラ52の外套面に接する搬送ベルト59により掴まれるまでシュレッダローラ52に向かって押し下げられる。搬送ベルト59は枚葉紙51をシュレッダローラ52,53の間のギャップ62へ搬送する。図1と図2と関連して記述したように枚葉紙51はストリップ63に裁断され、吸出し装置64で枚葉紙印刷機から除去される。   FIG. 3 shows a modified embodiment of the present invention in which a discharge device for a defective sheet 51 and a cutting device are arranged in the lower chain section of the chain discharge device of the sheet-fed printing press. Two shredder rollers 52 and 53 are arranged on the conveyance path to the stacked paper. The shafts 54 and 55 of the shredder rollers 52 and 53 are positioned parallel to each other and shifted in the vertical direction. The defective sheet 51 is not placed on the stacked paper but is continuously conveyed by the leading edge gripper 56. A control cam 57 is disposed in front of the shredder roller 52 in the conveyance path. This control cam 57 opens the gripper 56. The leading edge of the sheet 51 at the blow strip 58 is pushed down toward the shredder roller 52 until the leading edge is wound around the deflecting rollers 60 and 61 and is gripped by the conveying belt 59 in contact with the outer surface of the shredder roller 52. It is done. The conveyance belt 59 conveys the sheet 51 to the gap 62 between the shredder rollers 52 and 53. As described in connection with FIGS. 1 and 2, the sheet 51 is cut into strips 63 and removed from the sheet press by a suction device 64.
