Description

本発明は、シートスタックに排出されるシートを方向調整するための装置に関する。   The present invention relates to an apparatus for adjusting the direction of sheets discharged to a sheet stack.

シートを処理する機械の排紙装置に、シートスタックに排出されるシートのための前縁ストッパを設けることは公知である。搬送されてスタックを形成するシートは、前縁ストッパに当接されて、したがって正確にシートスタック上に排出される。   It is known to provide a leading edge stopper for a sheet discharged to a sheet stack in a sheet discharge device of a machine for processing sheets. The sheets that are conveyed to form the stack are abutted against the leading edge stopper and are therefore accurately discharged onto the sheet stack.

主に２種類の前縁ストッパ支承部が公知である。最初の前縁ストッパ支承部は、上位の支承箇所を有しており、上位の支承箇所から前縁ストッパが下向きに延びており、この場合前縁ストッパはスタックから離間する方向で旋回可能に支承されている。このような前縁ストッパは、たとえばドイツ連邦共和国特許出願公開第１０１５２８８４号明細書から公知である。ここでは有利には、旋回のあとで、補助スタック装置、たとえば支持板またはレーキを送られてくるシートまたはシート流に軽く押し込むことができる。このような構造の欠点によれば、個々の前縁ストッパのための、上位に位置する支承軸がサンプルシートの取出を妨げている。   Two main types of leading edge stopper bearings are known. The first leading edge stopper bearing portion has an upper bearing position, and the leading edge stopper extends downward from the upper bearing position. In this case, the leading edge stopper is pivotably supported in a direction away from the stack. Has been. Such a leading edge stopper is known, for example, from German Offenlegungsschrift 10 152 884. Here, advantageously, after swiveling, the auxiliary stacking device, for example a support plate or rake, can be pushed lightly into the incoming sheet or sheet stream. Due to the disadvantages of such a structure, the upper support shaft for the individual leading edge stoppers prevents the sample sheet from being removed.

これに対してドイツ連邦共和国特許出願公開第３４２３２６５号明細書には、下位に位置する前縁ストッパ軸を有する前縁ストッパが記載されている。この前線ストッパの有する利点によれば、旋回可能に配置された前縁ストッパが、簡単なサンプルシートの取出を実現しており、しかしながらその欠点によれば、補助スタック装置、たとえば支持板またはレーキをたとえばノンストップ運転に関して専ら前縁軸の下方で押し込むことしかできない。なぜならば上位のスタック領域へのアプローチは、前縁ストッパおよび前縁ストッパ軸によって妨げられるからである。
ドイツ連邦共和国特許出願公開第１０１５２８８４号明細書 ドイツ連邦共和国特許出願公開第３４２３２６５号明細書 In contrast, German Offenlegungsschrift 3,423,265 describes a leading edge stopper having a leading edge stopper shaft located below. According to the advantage of this front stopper, the pivotable leading edge stopper provides a simple sample sheet removal, however, according to its disadvantages, an auxiliary stack device, for example a support plate or rake, can be used. For example, for non-stop operation, it can only be pushed under the front edge shaft. This is because the approach to the upper stack area is hindered by the leading edge stopper and the leading edge stopper shaft.
German Patent Application No. 10152848 German Patent Application Publication No. 3423265

したがって本発明の課題は、冒頭で述べたような形式の、シートスタックに排出されるシートを方向調整するための装置を改良して、簡単なサンプルの取出を実現し、しかも補助スタック装置を上位のスタック領域でスタックに押し付けることのできるようなものを提供することである。   Accordingly, an object of the present invention is to improve a device for adjusting the direction of a sheet discharged to a sheet stack of the type described at the beginning, to realize a simple sample removal, and to improve the auxiliary stack device. It is to provide something that can be pushed onto the stack in the stack area.

この課題を解決するための本発明の装置によれば、前縁ストッパが、互いに平行に配置された２つの回転軸線を備えており、前縁ストッパが、選択的に上位の回転軸線または下位の回転軸線を中心に旋回可能に支承されている。   According to the apparatus of the present invention for solving this problem, the leading edge stopper includes two rotation axes arranged in parallel to each other, and the leading edge stopper is selectively connected to the upper rotation axis or the lower rotation axis. It is supported so as to be pivotable about the rotation axis.

本発明のように構成されていると、特に繰り返し動作、たとえばサンプル取出のために、シートを処理する機械の排紙装置へのアプローチが簡素化され、また補助スタック装置、たとえば支持板またはレーキの供給が簡素化され、簡単な操作が保証されている。   When configured in accordance with the present invention, the approach to the paper discharge device of the machine that processes the sheet is simplified, especially for repetitive operations such as sample removal, and the auxiliary stack device such as a support plate or rake is simplified. Supply is simplified and easy operation is guaranteed.

特に前縁ストッパ軸の機能の分離によって（前縁ストッパの回転軸線は複数の前縁ストッパを結合するための桁の外側に位置している）、前縁ストッパは選択的に下方または上方に旋回可能に配置することができる。前縁ストッパ軸のために独立した２つの回転軸線を配置したことによって、補助スタック装置を供給するための、前縁ストッパの上方旋回も、サンプル取出のための下方旋回も許容される。   In particular, by separating the function of the leading edge stopper shaft (the rotation axis of the leading edge stopper is located outside the beam for connecting the leading edge stoppers), the leading edge stopper is selectively pivoted downward or upward It can be arranged as possible. The arrangement of two independent axes of rotation for the leading edge stopper shaft allows the leading edge stopper to swivel to supply the auxiliary stacking device and the swiveling downward to remove the sample.

有利な実施形態では、前縁ストッパ軸は、周期的に駆動可能な旋回装置を備えており、旋回装置は、前縁ストッパを送られてくるシートのサイクルで運動させ、これによってスタック形成が最適化される。   In an advantageous embodiment, the leading edge stopper shaft is provided with a swiveling device that can be driven periodically, the swiveling device moving the leading edge stopper in the cycle of the fed sheet, so that the stack formation is optimal. It becomes.

次に本発明の実施の形態を図示の実施例を用いて詳しく説明する。   Next, embodiments of the present invention will be described in detail using the illustrated examples.

シート７を処置する機械、たとえば印刷機１は、給紙装置２と少なくとも１つの印刷装置３；４と排紙装置６とを備えている。シート７はシートスタック（積紙）８から取り出されて、個別化されるかまたはうろこ状にされて給紙台９を介して印刷装置３；４に供給される。印刷装置３；４は、公知の形式でそれぞれ版胴１１；ｌ２を備えている。版胴１１；１２はそれぞれフレキシブルな刷版を固定するための装置１３；１４を備えている。さらに各版胴１１；１２に、半自動式または全自動式に刷版交換を行うための装置１６；１７が対応配置されている。   A machine for treating the sheet 7, for example, the printing machine 1, includes a paper feeding device 2, at least one printing device 3; The sheet 7 is taken out from the sheet stack (stacked paper) 8, individualized or scaled, and supplied to the printing apparatus 3; 4 through the sheet feeding table 9. The printing devices 3; 4 are each provided with a plate cylinder 11; Each of the plate cylinders 11; 12 is provided with a device 13; 14 for fixing a flexible printing plate. Furthermore, each plate cylinder 11; 12 is provided with a corresponding device 16; 17 for performing plate change in a semi-automatic or fully automatic manner.

シートスタック８は、昇降制御可能なスタックプレート１０を備えている。シート７の取出は、いわゆる吸着ヘッド１８を用いてシートスタック８の上面から行われ、吸着ヘッド１８は、とりわけシート７を個別化するための幾つかの昇降サッカ１９および送りサッカ２１を備えている。さらに上位に位置するシート層をほぐすための送風装置２２、およびスタック後ガイドのための接触エレメント２３が設けられている。シートスタック８、特にシートスタック８の上位のシート７を方向調整するために、側方および後方の幾つかのストッパ２４が設けられている。   The sheet stack 8 includes a stack plate 10 that can be controlled to move up and down. The sheet 7 is taken out from the upper surface of the sheet stack 8 by using a so-called suction head 18, and the suction head 18 is provided with several lifting suckers 19 and feed suckers 21 for individualizing the sheets 7, among others. . Further, a blower 22 for loosening a sheet layer located at the upper level and a contact element 23 for a post-stack guide are provided. In order to adjust the direction of the sheet stack 8, in particular the upper sheets 7 of the sheet stack 8, several lateral and rear stops 24 are provided.

排紙装置６は、とりわけシートスタック２７を収容するためのメーンスタックプレート２６を備えている。シート７はチェングリッパシステム２８によってシートスタック２７に供給される。前縁ストッパ（前当て）２９は、上位のスタック領域でスタック前縁３１に沿って配置されていて、かつ正確なスタック形成を助成する。処理しようとするシート幅（紙判幅）にわたって分配配置するために、幾つかの前縁ストッパ２９が相互間隔を有して共通の桁３２に配置されている。桁３２は端部でそれぞれレバー３３；３４を備えており、レバー３３；３４は自由端部で継手３６；３７と枢着式に結合されている。両側でシートスタック２７の後方に配置された枢支箇所は、共通の上位の回転軸線３８を有している。枢支箇所とは反対側の端部で、継手３６；３７は電動モータ４２；４３の出力軸３９；４１に取り付けられている。出力軸３９；４１は共通の下位の回転軸線４４を有している。   The paper discharge device 6 includes a main stack plate 26 for accommodating the sheet stack 27, among others. The sheet 7 is supplied to the sheet stack 27 by a chain gripper system 28. The front edge stopper (front pad) 29 is disposed along the stack front edge 31 in the upper stack area and assists accurate stack formation. A number of leading edge stoppers 29 are arranged in a common girder 32 with a mutual spacing in order to distribute them over the sheet width (paper width) to be processed. The spar 32 is provided at its end with a lever 33; 34, respectively, which is pivotally connected to a joint 36; 37 at its free end. The pivot points arranged on both sides behind the sheet stack 27 have a common upper rotation axis 38. The joint 36; 37 is attached to the output shaft 39; 41 of the electric motor 42; 43 at the end opposite to the pivot point. The output shafts 39; 41 have a common lower rotation axis 44.

電動モータ４２；４３は、図３に示したように、前縁ストッパ２９を、下位の回転軸線４４を中心に周期的に繰り返される小さな旋回運動で変位させる。旋回運動は、有利にはシートを処理する機械のサイクルで行われ、かつシートスタック２７上の正確なシート排出を保証する。   As shown in FIG. 3, the electric motors 42 and 43 displace the leading edge stopper 29 by small turning motions that are periodically repeated about the lower rotation axis 44. The swivel movement is advantageously performed in the cycle of the machine that processes the sheets and ensures accurate sheet ejection on the sheet stack 27.

ここでは旋回運動は、たとえばモータの反転または伝動装置たとえばカム−ローラ−伝動装置によって形成される。   Here, the swivel movement is formed, for example, by a motor reversal or a transmission device, for example a cam-roller transmission.

前縁ストッパ２９は、選択的に鉛直方向から、上位の回転軸線３８または下位の回転軸線４４を中心に水平位置に旋回することができる。上位の回転軸線３８は有利にはスタック上縁高さまたはその下に配置されている。   The leading edge stopper 29 can be selectively turned from the vertical direction to a horizontal position around the upper rotation axis 38 or the lower rotation axis 44. The upper axis of rotation 38 is preferably arranged at or below the stack upper edge height.

したがって図５に示したように、シートスタック２７から回転軸線３８を中心に上方旋回する前縁ストッパ２９の旋回運動は、全シートスタック２７に対する係合を解除する。したがって補助スタック装置たとえば支持板またはレーキをスタック領域の任意の位置に取り付けることができる。   Therefore, as shown in FIG. 5, the pivoting movement of the leading edge stopper 29 that pivots upward from the sheet stack 27 around the rotation axis 38 releases the engagement with respect to all the sheet stacks 27. Thus, auxiliary stack devices such as support plates or rakes can be attached at any location in the stack area.

図４に示したように、シートスタック２７から下位の回転軸線４４を中心に下方旋回する前縁ストッパ２９の旋回運動は、上位のシートスタック領域に対する係合を解除するので、たとえば簡単なサンプルシートの取出が実現される。   As shown in FIG. 4, the pivoting movement of the leading edge stopper 29 that pivots downward from the sheet stack 27 about the lower rotation axis 44 releases the engagement with the upper sheet stack region. Is realized.
