Description

本発明は、印刷機本体から排出される多量の印刷用紙を、綺麗に揃えて積載するための紙受け装置における紙受け処理方法に関する。 The present invention relates to a paper receiving method in a paper receiving device for neatly stacking a large amount of printing paper discharged from a printing machine main body.
従来、印刷機本体から排出される多量の用紙を、揃えて積載する紙受け装置として、印刷機本体の用紙排出側の端部にU字形成ガイド機構を配置し、紙受け台上に、用紙幅より狭い間隔で一対の幅ガイドを配置した装置があり、紙受け処理方法として、前記U字形成ガイド機構により、印刷済みの用紙を、用紙幅方向(用紙排出方向と直角方向)の両端が高くなるU字状に形成して、紙受け台の上方に排出し、前記一対の幅ガイドにて、前記用紙をU字状態に維持しつつ落下させ、紙受け台に積載している(特許文献1及び2参照)。   Conventionally, as a paper receiving device that stacks a large amount of paper discharged from the printing machine main body, a U-shaped formation guide mechanism is arranged at the end of the printing machine main body on the paper discharge side, and the paper is placed on the paper receiving table. There is an apparatus in which a pair of width guides are arranged at an interval narrower than the width. As a paper receiving processing method, the U-shaped formation guide mechanism is used to place printed paper at both ends in the paper width direction (perpendicular to the paper discharge direction). It is formed in a U-shape that rises, is discharged above the paper cradle, is dropped while maintaining the U-shape with the pair of width guides, and is loaded on the paper cradle (patent) Reference 1 and 2).
また、前記紙受け装置に、昇降自在なエレベータ式の紙受け台を備えたものがあり、積載用紙の積載量を検知センサーにより検知し、印刷済みの用紙が所定高さまで積載された状態となったときに、自動的に紙受け台を下降するようになっている(特許文献2参照)。   In addition, the paper receiving device includes an elevator-type paper receiving table that can be moved up and down. The amount of stacked paper is detected by a detection sensor, and the printed paper is stacked to a predetermined height. The paper tray is automatically lowered (see Patent Document 2).
特開平11−43258号公報(第1,第2及び第4図)Japanese Patent Laid-Open No. 11-43258 (FIGS. 1, 2 and 4) 特開2004−83221号公報(図2及び図6等)Japanese Unexamined Patent Publication No. 2004-83221 (FIGS. 2 and 6 etc.)
U字状態で排出される印刷済みの用紙を、単に、一対の幅ガイド間でU字状態を維持しつつ落下させる方法では、用紙の種類によって、特に、硬くて腰の強い(剛性の高い)用紙を使用する場合、落下途中で幅ガイド間に用紙が引っ掛かかり、後続の用紙が次々とその上に積載され、積載不良の原因となることがある。   In the method of simply dropping printed paper discharged in a U-shape while maintaining the U-shape between a pair of width guides, it is particularly hard and firm (high rigidity) depending on the type of paper. When using paper, the paper is caught between the width guides in the middle of dropping, and subsequent papers are stacked one after another, which may cause a stacking failure.
また、紙受け台が昇降するエレベータ式の紙受け装置では、前記検知センサーが、引っ掛かった用紙を検出することにより、誤った積載量を検知することになり、所定の積載量まで達していない状態で、エレベータが下降し続けるという不具合が生じることがある。エレベータの下降動作が所定時間以上続くと、紙受け装置が異常状態(ジャム状態)であると検出し、自動的に印刷動作を停止する(特許文献2の段落「0103」〜「0106」)。このように、印刷動作を停止することは、作業能率の低下につながる。   Further, in an elevator type paper receiving apparatus in which the paper receiving table is raised and lowered, the detection sensor detects an erroneously loaded amount by detecting the caught paper, and does not reach a predetermined loaded amount. Therefore, there may be a problem that the elevator continues to descend. If the lowering operation of the elevator continues for a predetermined time or more, it is detected that the paper receiving device is in an abnormal state (jam state), and the printing operation is automatically stopped (paragraphs “0103” to “0106” in Patent Document 2). Thus, stopping the printing operation leads to a reduction in work efficiency.
なお、本件出願人は、上記のような紙受け装置を有する孔版印刷機において、印刷版胴を内蔵する印刷機本体に対し、給紙装置全体を印刷用紙の幅方向に移動することにより、印刷用紙に対する画像の用紙幅方向の位置を調節するできる孔版印刷機を開発している(未公開)。かかる構造の場合、紙受け台のU字状態保持部材上の所定位置に印刷用紙を積載するために、紙受け装置全体を給紙装置と同様に用紙幅方向に移動しようとすれば、印刷機全体が大形化し、構造がさらに複雑化する。   In addition, in the stencil printing machine having the paper receiving device as described above, the applicant of the present invention performs printing by moving the entire paper feeding device in the width direction of the printing paper with respect to the printing machine body incorporating the printing plate cylinder. A stencil printing machine that can adjust the position of the image in the paper width direction with respect to the paper has been developed (unpublished). In the case of such a structure, in order to stack the printing paper at a predetermined position on the U-shaped holding member of the paper receiving tray, if the entire paper receiving device is moved in the paper width direction like the paper feeding device, the printing machine The whole size is increased and the structure is further complicated.
(発明の目的)
本発明は、印刷用紙の種類に関係無く、印刷機本体からU字状態で排出される印刷済みの用紙を、U字状態に維持しつつ、引っ掛かることなく、紙受け台上に整然とU字状に積載できる紙受け処理方法を提供することを目的としている。また、印刷機本体から排出ささる印刷済みの用紙の幅方向の位置が、紙受け装置のU字状態保持部材の用紙幅方向の位置とずれていても、速やかにU字状態保持部材の用紙幅方向の中心線と印刷用紙の幅方向の中心線とが合致するように、位置補正し、積載できる紙受け処理方法を提供することも目的としている。

持ち上げガイド部51は、三角錐状に形成されており、側方から見て、排紙ベルト21の上面に略一致する高さの後端51aから前方に向けて所定角度をもって高くなり、前端が最も高くなっている。また、前方から見て、左右幅の中央側から端部側に向かって高くなっており、さらに、上方から見て、前方に向かって左右幅が広がるように形成されている。このU字形成ガイド機構28によると、用紙Pの左右幅の中央部分を吸引ベルト31で吸引しつつ、用紙Pの左右端部を、持ち上げガイド部51により徐々に持ち上げ、用紙Pの全体を上向きのU字状に変形させて、前方(F)に排出する。   The lifting guide portion 51 is formed in a triangular pyramid shape, and when viewed from the side, the lifting guide portion 51 becomes higher at a predetermined angle from the rear end 51a having a height substantially coincident with the upper surface of the paper discharge belt 21, and the front end is increased. It is the highest. In addition, the width is increased from the center side to the end side when viewed from the front, and further, the width is increased from the center toward the front as viewed from above. According to this U-shaped formation guide mechanism 28, the left and right end portions of the paper P are gradually lifted by the lifting guide portion 51 while the central portion of the left and right width of the paper P is sucked by the suction belt 31, and the entire paper P is directed upward. It is transformed into a U shape and discharged forward (F).
(紙受け装置の構成)
図6において、U字状態保持部材42は、左右幅の中心線O3に対して左右対称に配置されると共に、前記中心線O3から左右幅方向の外方に向かって高くなる三角形状に形成されている。また、各U字状態保持部材42は、左右幅中央側の端部が、紙受け台41に、回動軸42aを介して回動自在に支持されており、回動軸42a回りに回動することにより、紙受け台41の上面に対する傾斜角度θ1を変更できるようになっている。すなわち、剛性の高い厚紙等を積載する場合は傾斜角θ1を小さくし、剛性の低い薄い紙等を積載する場合には傾斜角度紙θ1を大きく設定できるようになっている。
(Configuration of paper receiving device)
In FIG. 6, the U-shaped state holding member 42 is symmetrically arranged with respect to the center line O3 of the left and right width, and is formed in a triangular shape that increases from the center line O3 toward the outside in the left and right width direction. ing. In addition, each U-shaped state holding member 42 has an end portion on the center side of the left and right widths supported by the paper receiving base 41 so as to be rotatable via a rotation shaft 42a, and rotates around the rotation shaft 42a. By doing so, the inclination angle θ1 with respect to the upper surface of the paper tray 41 can be changed. That is, the inclination angle θ1 can be reduced when stacking thick paper with high rigidity, and the inclination angle paper θ1 can be set large when stacking thin paper with low rigidity.
左右の幅ガイド44,45は、紙受け台41の上面に対して略垂直姿勢に立設される共に、左右方向(用紙幅方向)に移動可能となっており、それぞれベルト式伝動機構等の伝動機構54、56等を介して駆動モータ53、55に連結し、個別に左右方向(用紙幅方向)に移動できるようになっている。   The left and right width guides 44 and 45 are erected in a substantially vertical posture with respect to the upper surface of the paper tray 41 and are movable in the left and right direction (paper width direction). It is connected to drive motors 53 and 55 via transmission mechanisms 54 and 56, etc., and can be moved individually in the left-right direction (paper width direction).
図7に示すように、両幅ガイド44,45は、通常、両ガイド面の間隔D1が平面状態の用紙幅A1(図3参照)よりも狭くなるガイド位置に位置しており、これにより、印刷済みの用紙Pを、両ガイド部材44,45間でU字状態に維持しつつ、U字状態保持部材42上まで落下ガイドするようになっている。   As shown in FIG. 7, the both width guides 44 and 45 are usually located at the guide position where the distance D1 between the two guide surfaces is narrower than the sheet width A1 (see FIG. 3) in the flat state. The printed paper P is guided to drop onto the U-shaped state holding member 42 while maintaining the U-shaped state between the guide members 44 and 45.
本実施の形態では、幅ガイド44,45の構成として、上記構造に加え、駆動モータ53,55により、図6に実線で示すように、前記ガイド位置よりも左右方向の外方側へ離れた退避位置まで、移動できるようになっている。各幅ガイド44,45におけるガイド位置と退避位置との間の距離W1は、少なくとも一方の幅ガイド45が退避位置まで移動した時に、その一方の幅ガイド45のガイド面が、印刷機本体1から排出される用紙Pの左右方向の一方の端縁(図6では右端縁)に略相当する位置にくるように、設定されている。具体的には、図4のように、給紙装置2の給紙ユニット16を左右方向の一方、たとえば右方にd1だけ移動した時に、その移動量d1と略同距離W1だけ、右方向に移動した位置を、退避位置と設定している。   In the present embodiment, the width guides 44 and 45 are separated from the guide position by the drive motors 53 and 55 outward in the left-right direction as shown by the solid lines in addition to the structure described above. It can be moved to the retreat position. The distance W1 between the guide position and the retracted position in each of the width guides 44 and 45 is such that when at least one width guide 45 moves to the retracted position, the guide surface of the one width guide 45 is separated from the printing press main body 1. It is set so as to come to a position substantially corresponding to one edge (the right edge in FIG. 6) in the left-right direction of the discharged paper P. Specifically, as shown in FIG. 4, when the paper feeding unit 16 of the paper feeding device 2 is moved by d1 in one of the left and right directions, for example, to the right, it is moved to the right by approximately the same distance W1 as the movement amount d1. The moved position is set as the retreat position.
なお、後で詳しく説明するが、実際の紙受け処理作業においては、左右の幅ガイド44,45の一方のみがガイド位置と退避位置との間で往復移動し、残りの幅ガイドは、ガイド位置に固定された状態に維持される。   As will be described in detail later, in actual paper receiving processing, only one of the left and right width guides 44 and 45 reciprocates between the guide position and the retracted position, and the remaining width guides are moved to the guide position. It is maintained in a fixed state.
図3において、止めガイド46は、前後方向(用紙排出方向F)に対して略直角な姿勢で配置されており、図示しないが、ベルト式電動機構等を介して駆動モータに連結しており、駆動モータにより、前後方向に移動できるようになっている。また、前記U字状態保持部材42は、前後方向に間隔を置いて複数対に配置されている。   In FIG. 3, the stop guide 46 is disposed in a posture substantially perpendicular to the front-rear direction (paper discharge direction F), and although not shown, is connected to a drive motor via a belt-type electric mechanism or the like. The drive motor can move in the front-rear direction. The U-shaped state holding members 42 are arranged in a plurality of pairs at intervals in the front-rear direction.
(給紙装置及び紙受け装置の左右位置調節)
(1)図3において、給紙装置2上の左右の幅ガイド13間の中心線を符号O1で示し、印刷機本体1内の印刷版胴11の左右幅の中心線を符号O2で示し、前述のように紙受け装置2のU字状保持部材42の左右幅の中心線を符号O3で示し、また、用紙Pの左右幅をA1で示し、用紙Pの左右幅中心線を符号O4で示している。図3の状態は、印刷機上の前記中心線O1,O2,O3が同一直線上に揃っている状態を示している。なお、説明の都合上、給紙装置2の左右の幅ガイド13間の中心線O1を、簡単に「給紙側中心線」と称し、印刷版胴11の左右幅中心線O2を、簡単に「版胴中心線」と称し、紙受け装置2のU字状保持部材42の左右幅の中心線O3を、簡単に「U字状態中心線」と称し、用紙Pの左右幅A1を、簡単に「用紙幅」と称し、用紙Pの左右幅の中心線O4を、簡単に「用紙幅中心線」と称し、て、以下説明する。
(Adjusting the left and right positions of the paper feeder and paper receiver)
(1) In FIG. 3, the center line between the left and right width guides 13 on the paper feeder 2 is indicated by reference numeral O1, the center line of the left and right width of the printing plate cylinder 11 in the printing machine body 1 is indicated by reference numeral O2, As described above, the center line of the left and right width of the U-shaped holding member 42 of the paper receiving apparatus 2 is indicated by reference symbol O3, the left and right width of the paper P is indicated by A1, and the left and right width center line of the paper P is indicated by reference symbol O4. Show. The state of FIG. 3 shows a state where the center lines O1, O2, and O3 on the printing press are aligned on the same straight line. For convenience of explanation, the center line O1 between the left and right width guides 13 of the sheet feeding device 2 is simply referred to as a “sheet feeding side center line”, and the left and right width center line O2 of the printing plate cylinder 11 is simply denoted. The center line O3 of the left and right width of the U-shaped holding member 42 of the paper receiving apparatus 2 is simply referred to as the “plate cylinder center line”, simply referred to as the “U-shaped center line”, and the left and right width A1 of the paper P is simply The center line O4 of the right and left width of the sheet P is simply referred to as “sheet width center line” and will be described below.
(2)図3において、印刷を開始する前、用紙Pを給紙装置2に積載する時には、給紙装置2の幅ガイド13の左右幅D0を、用紙幅A1と略一致するように調節する。この場合、左右の幅ガイド13を給紙側中心線O1に対して同時に左右対称に移動することにより調節する。続いて、紙受け装置3の幅ガイド44の左右幅D1を、前記用紙幅A1よりも少し短い幅、具体的には、使用する大きさの用紙PをU字状に安定して積載できる幅に設定する。この場合も、給紙装置2の調節と同様に、左右の幅ガイド44、45を同時に、U字状態中心線O3に対して左右対称に移動する。 (2) In FIG. 3, before starting printing, when the paper P is stacked on the paper feeding device 2, the left and right width D0 of the width guide 13 of the paper feeding device 2 is adjusted so as to substantially match the paper width A1. . In this case, adjustment is performed by moving the left and right width guides 13 simultaneously symmetrically with respect to the paper feed side center line O1. Subsequently, the left and right width D1 of the width guide 44 of the paper receiving device 3 is a width that is slightly shorter than the paper width A1, specifically, a width that allows the paper P of a size to be used to be stably stacked in a U-shape. Set to. Also in this case, similarly to the adjustment of the sheet feeding device 2, the left and right width guides 44 and 45 are simultaneously moved symmetrically with respect to the U-shaped center line O3.
(3)上記のように、用紙幅A1に対応するように給紙装置2の幅ガイド13の左右幅D0を調節し、かつ、前記左右幅D0よりも少し短くなるように紙受け装置3の幅ガイド44、45の左右幅D1を調節した後、印刷用紙P上の画像の左右方向の位置を調節する。この場合、図4に示すように、給紙装置2の給紙ユニット16を、印刷版胴11に対して左右方向に移動調節する。たとえば、給紙ユニット16の全体を右方向に距離d1だけ移動することにより、印刷用紙P上の画像の左右方向の位置は、左方に距離d1だけ移動することになる。 (3) As described above, the left and right width D0 of the width guide 13 of the paper feeding device 2 is adjusted so as to correspond to the paper width A1, and the paper receiving device 3 is adjusted to be slightly shorter than the left and right width D0. After adjusting the left-right width D1 of the width guides 44, 45, the position of the image on the printing paper P in the left-right direction is adjusted. In this case, as shown in FIG. 4, the paper feeding unit 16 of the paper feeding device 2 is moved and adjusted with respect to the printing plate cylinder 11 in the left-right direction. For example, by moving the entire paper feed unit 16 by the distance d1 in the right direction, the position in the left-right direction of the image on the printing paper P is moved to the left by the distance d1.
上記給紙装置2の左右方向の移動調節と同時に、紙受け装置2においては、左側の幅ガイド44はガイド位置に固定状態とし、右側の幅ガイド45は、紙受け処理作業中において、印刷機本体1から排出される印刷用紙1枚毎に、図4で示す退避位置と図5で示すガイド位置との間で往復移動するように設定する。この調節作業において、紙受け装置3又は紙受け台41は左右方向に移動しないので、U字状態保持部材42のU字状態中心線O3は、給紙側中心線O1に対して、相対的に左方に距離d1だけずれた状態となっている。   Simultaneously with the adjustment of the lateral movement of the paper feeding device 2, in the paper receiving device 2, the left width guide 44 is fixed at the guide position, and the right width guide 45 is used in the printing machine during the paper receiving processing operation. For each sheet of printing paper ejected from the main body 1, it is set so as to reciprocate between the retracted position shown in FIG. 4 and the guide position shown in FIG. In this adjustment operation, the paper receiving device 3 or the paper receiving base 41 does not move in the left-right direction, so that the U-shaped center line O3 of the U-shaped state holding member 42 is relatively relative to the paper feeding side center line O1. The distance is shifted to the left by a distance d1.
(印刷作業及び紙受け処理作業)
(1)図1において、画像読取装置4で原稿を読み取り、製版装置6で製版し、製版後の孔版原紙(マスター)を印刷版胴11に装着する。
(Printing work and paper receiving processing work)
(1) In FIG. 1, an original is read by the image reading device 4, the plate making device 6 makes a plate, and the stencil sheet (master) after plate making is mounted on the printing plate cylinder 11.
(2)給紙装置2の給紙台17上に所定枚数の印刷用紙Pを積載し、印刷作業をスタートすると、給紙台17上の印刷用紙Pは、エア吸着式搬送ベルト機構18及び捌き板19の作用により、最上位から一枚ずつ孔版印刷機本体1内の搬送機構9に送り込まれる。 (2) When a predetermined number of print sheets P are stacked on the sheet feed tray 17 of the sheet feeder 2 and the printing operation is started, the print sheets P on the sheet feed tray 17 are separated from the air adsorption transport belt mechanism 18 and the paper. Due to the action of the plate 19, the sheets are fed one by one from the top to the transport mechanism 9 in the stencil printing machine main body 1.
(4)孔版印刷機本体内1において、搬送機構9により前方に搬送される印刷用紙Pは、タイミングローラ26が印刷版胴11の回転と同期して駆動することにより、印刷版胴11と押圧ローラ12の間の画像形成部分に送り込まれ、この画像形成部において、印刷用紙の表面に印刷が施される。 (4) In the stencil printing machine main body 1, the printing paper P conveyed forward by the conveyance mechanism 9 is pressed against the printing plate cylinder 11 by the timing roller 26 being driven in synchronization with the rotation of the printing plate cylinder 11. The image is sent to an image forming portion between the rollers 12, and printing is performed on the surface of the printing paper in the image forming portion.
(5)印刷後の用紙Pは排紙装置8に排出され、排紙ベルト31に吸着された状態で前方に搬送されると共に、U字形成ガイド機構28により、上向きのU字状態に形成され、紙受け装置3の紙受け台41の上方に排出される。この時、前記図4のように、給紙装置2を右方に距離d1だけ移動している場合には、図6のように、用紙Pは、用紙幅中心線O4がU字状態中心線O3から右方に略d1だけ状態で排出される。 (5) The printed paper P is discharged to the paper discharge device 8 and conveyed forward while being attracted to the paper discharge belt 31, and is formed in an upward U-shaped state by the U-shaped formation guide mechanism 28. Then, the paper is discharged above the paper receiving table 41 of the paper receiving device 3. At this time, when the paper feeding device 2 is moved to the right by the distance d1 as shown in FIG. 4, the paper width center line O4 of the paper P is U-shaped center line as shown in FIG. It is discharged from O3 to the right by approximately d1.
(9)紙受け装置3では、図6に示すように、左側の幅ガイド44はガイド位置に固定されているが、右側の幅ガイド45は退避位置まで移動した状態となっており、かかる状態の幅ガイド44,45間に、前述のようにU字状態の印刷済みの用紙Pが排出される。すなわち、排出される用紙Pの右端縁が、右側幅ガイド45のガイド面と略同じ位置となるか、右側ガイド45のガイド面よりも少し左方に位置した状態で、排出される。 (9) In the paper receiver 3, as shown in FIG. 6, the left width guide 44 is fixed at the guide position, but the right width guide 45 is moved to the retracted position. As described above, the printed sheet P in the U-shape is discharged between the width guides 44 and 45. That is, the paper P to be discharged is discharged in a state where the right edge of the paper P is substantially at the same position as the guide surface of the right width guide 45 or slightly to the left of the guide surface of the right guide 45.
(10)用紙Pが両幅ガイド44,45間で落下している途中において、図6に仮想線で示すように、右側幅ガイド45を退避位置からガイド位置まで左方に移動する。これにより、落下中の用紙Pは左方に押され、用紙幅中心線O4がU字状態中心線O3と略一致する位置まで用紙Pは位置補正され、U字状態保持部材42上の所定位置(用紙中心線O4とU字状態中心線O3とが一致した位置)に、U字を保持した状態で積載される。 (10) While the paper P is falling between the width guides 44 and 45, the right width guide 45 is moved to the left from the retracted position to the guide position, as indicated by a virtual line in FIG. As a result, the falling paper P is pushed to the left, and the paper P is position-corrected to a position where the paper width center line O4 substantially coincides with the U-shaped center line O3. The paper is stacked in a state where the U-shape is held at the position where the sheet center line O4 and the U-shape state center line O3 coincide.
後から順次排出される印刷済みの用紙Pに対しても、右側の幅ガイド45は、用紙一枚に対して、ガイド位置と退避位置との間を一往復し、各用紙Pの左右方向の位置を、左方へ位置補正して、U字状態保持部材42上の所定位置に順次積載する。   The right width guide 45 also makes a round trip between the guide position and the retracted position with respect to one sheet of paper P, which is sequentially ejected later, and the left and right direction of each sheet P The positions are corrected to the left and sequentially stacked at predetermined positions on the U-shaped state holding member 42.
また、該実施の形態では、止めガイド46が前後方向にジョガー動作するので、紙受け台41のU字状態保持部材42上に積載される用紙Pの前後方向の位置も、綺麗に揃えられる。   In this embodiment, since the stop guide 46 performs a jogger operation in the front-rear direction, the positions in the front-rear direction of the sheets P stacked on the U-shaped holding member 42 of the paper receiving base 41 are also neatly aligned.
上記紙受け処理作業の説明は、図4及び図5のように、給紙装置2の給紙ユニット16を、印刷版胴11に対して右方に位置調節した場合を説明したが、給紙装置2の給紙ユニット16を、図3の左方に位置調節した場合には、右側の幅ガイド45をガイド位置に固定し、左側の幅ガイド44を、ガイド位置と退避位置との間で往復移動させることにより、紙受け装置3に排出される用紙Pを、右方に位置補正する。   In the description of the paper receiving process, the case where the paper feeding unit 16 of the paper feeding device 2 is adjusted to the right with respect to the printing plate cylinder 11 as shown in FIGS. When the position of the sheet feeding unit 16 of the apparatus 2 is adjusted to the left in FIG. 3, the right width guide 45 is fixed to the guide position, and the left width guide 44 is moved between the guide position and the retracted position. By reciprocating, the position of the paper P discharged to the paper receiving device 3 is corrected to the right.
上記紙受け処理方法によると、印刷機本体1からU字状態で排出された印刷済みの用紙Pは、落下途中で幅ガイド44,45に引っ掛かることなく、紙受け台41のU字状態保持部材42上に整然と揃った状態で積載される。また、印刷機本体1から排出される用紙Pの用紙幅中心線O4が、U字状態保持部材42のU字状態中心線O3からずれていても、右側(又は左側)の幅ガイド45が退避位置とガイド位置との間で往復移動することにより、用紙PをU字状態保持部材42上の所定位置へ確実に移動させることができる。特に、給紙装置2の給紙ユニット16全体が左右方向に移動することにより、印刷用紙P上の画像の左右方向の位置を調節する印刷機であっても、印刷機本体1から排出される用紙Pを、確実にU字状態保持部材42の所定位置に整然と積載することができる。   According to the paper receiving processing method, the printed paper P discharged from the printing machine main body 1 in a U-shaped state is not caught by the width guides 44 and 45 in the middle of dropping, and the U-shaped holding member of the paper receiving base 41 is used. It is loaded in an orderly manner on 42. Even if the sheet width center line O4 of the sheet P discharged from the printing press main body 1 is deviated from the U-shaped state center line O3 of the U-shaped state holding member 42, the right (or left) width guide 45 is retracted. By reciprocating between the position and the guide position, the paper P can be reliably moved to a predetermined position on the U-shaped state holding member 42. In particular, even if the printing machine adjusts the position of the image on the printing paper P in the horizontal direction by moving the entire paper feeding unit 16 of the paper feeding device 2 in the horizontal direction, it is discharged from the printing machine body 1. The sheets P can be reliably stacked in a predetermined position on the U-shaped state holding member 42 reliably.
また、排出される用紙Pを一枚ずつ位置補正するので、総ての用紙Pを、確実に、U字状態保持部材42上の所定位置に、綺麗に整えて積載することができる。   Further, since the positions of the discharged sheets P are corrected one by one, all the sheets P can be reliably arranged and stacked at predetermined positions on the U-shaped state holding member 42 with certainty.
(第1の実施の形態の幅ガイドの変形例)
(1)図8及び図9は幅ガイドの変形例であり、図8は、図6と同様に右側幅ガイド45が退避位置に位置している状態、図9は図7と同様に右側幅ガイド45が元のガイド位置に戻った状態である。左右の幅ガイド44,45は、上半部が下半部44a,45aよりもU字状態中心線O3側に来るように、階段状に形成されている。したがって、左右の幅ガイド44,45の上半部の間隔D3は、下半部の間隔D1よりも更に狭くなっている。
(Modification of the width guide of the first embodiment)
(1) FIGS. 8 and 9 show modified examples of the width guide. FIG. 8 shows a state in which the right width guide 45 is located at the retracted position as in FIG. 6, and FIG. 9 shows the right width as in FIG. In this state, the guide 45 is returned to the original guide position. The left and right width guides 44 and 45 are formed in a step shape so that the upper half portion is closer to the U-shaped center line O3 side than the lower half portions 44a and 45a. Therefore, the distance D3 between the upper half portions of the left and right width guides 44 and 45 is further narrower than the distance D1 between the lower half portions.
該変形例によると、用紙PがU字状態保持部材42上に積載された時に、用紙Pは少し広がるので、用紙を更に整然と積載することができる。   According to the modified example, when the paper P is stacked on the U-shaped state holding member 42, the paper P spreads a little, so that the paper can be stacked more orderly.

The width guides 44 and 45 include first guide members 44-1 and 45-1 on the inner side of the left and right width, and first guide members 44-1 and 45-1 on the outer side of the left and right width. It is comprised by 2 guide members 44-2 and 45-2.
図16において、内側の第1ガイド部材44−1,45−1は、略垂直な平板状に形成されると共に、前後方向に間隔を置いて、たとえば3つの矩形状の窓孔が形成されている。また、内側の第1ガイド部材44−1,45−1の下半部44a,45aは、前後方向に相互に間隔をおいた一対の押圧片により構成されており、上記各下半部44a、45aは第1ガイド部材44−1,45−1の上半部に対し、左右幅の外方側に来るように階段状に形成されている。外側の第2ガイド部材44−2,45−2は、略垂直な枠状部分の下端に、第1ガイド部材44−1,45−1の下端よりも下方に突出すると共に、前記枠状部分よりも左右幅の内方側に突出する押圧部44b、45bが形成されている。   In FIG. 16, the inner first guide members 44-1 and 45-1 are formed in a substantially vertical flat plate shape, and, for example, three rectangular window holes are formed at intervals in the front-rear direction. Yes. Further, the lower half portions 44a, 45a of the inner first guide members 44-1, 45-1 are configured by a pair of pressing pieces spaced from each other in the front-rear direction, and each of the lower half portions 44a, 45a is formed in a step shape so as to come to the outer side of the left-right width with respect to the upper half of the first guide members 44-1, 45-1.

(紙受け処理作業)
(1)薄い用紙Pの位置補正及びジョガーを行う場合
薄い用紙Pを紙受け処理する場合には、前述の用紙Pの位置補正作業後に、第2ガイド部材44−2,45−2によるジョガー動作を行う。以下、詳しく説明する。
(Paper receiving processing work)
(1) When performing thin paper P position correction and jogger When thin paper P is subjected to paper receiving processing, the jogger operation by the second guide members 44-2 and 45-2 after the above-described paper P position correction work. I do. This will be described in detail below.
図19及び図20は、薄い用紙Pを位置補正する工程を示しており、通常(非ジョガー動作時)、第2のガイド部材44−2,45−2の押圧部44b、45bの押さえ面は、前述のように、第1のガイド部材44−1,45−1の下半部44a、45aと同一面に設定されている。用紙の位置補正を行う場合には、図19に実線で示すように、一方、たとえば左側の第1ガイド部材44−1と第2ガイド部材44−2は、ガイド位置に固定しておき、右側の第1ガイド部材45−1と第2ガイド部材45−2を、実線で示す退避位置と仮想線で示すガイド位置(図20の位置)との間で往復移動させることにより、用紙Pを左方に移動し、用紙幅中心線O4をU字状態中心線O3に一致させる。   19 and 20 show the process of correcting the position of the thin paper P. Normally, the pressing surfaces of the pressing portions 44b and 45b of the second guide members 44-2 and 45-2 are as follows (during non-jogger operation). As described above, the first guide members 44-1, 45-1 are set on the same plane as the lower half portions 44a, 45a. When the paper position is corrected, as shown by a solid line in FIG. 19, on the other hand, for example, the first guide member 44-1 and the second guide member 44-2 on the left side are fixed at the guide positions and the right side is fixed. The first guide member 45-1 and the second guide member 45-2 are reciprocated between a retracted position indicated by a solid line and a guide position indicated by an imaginary line (the position shown in FIG. 20), whereby the paper P is moved to the left. The sheet width center line O4 is made to coincide with the U-shaped state center line O3.
図21は、上記位置補正の後、ジョガー動作を行う工程を示している。左右の第1部材44−1,45−1を共にガイド位置に固定した状態とし、左右の第2ガイド部材44−2、45−2を、図20の状態と図21の状態との間で左右幅に往復移動させる。すなわち、左右の第2ガイド部材44−2,45−2にジョガー動作をさせ、第2のガイド部材44−2,45−2の押圧部44b、45bにより、用紙Pの左右の端縁を揃えると共に、用紙Pを上方から見て右又は左に傾いている場合には、前後方向に真っ直ぐ延びる状態に補正する。   FIG. 21 shows a step of performing a jogger operation after the position correction. The left and right first members 44-1 and 45-1 are both fixed at the guide position, and the left and right second guide members 44-2 and 45-2 are placed between the state of FIG. 20 and the state of FIG. Move back and forth to the left and right width. That is, the left and right second guide members 44-2 and 45-2 are jogged and the left and right edges of the paper P are aligned by the pressing portions 44b and 45b of the second guide members 44-2 and 45-2. At the same time, when the sheet P is tilted to the right or left as viewed from above, the sheet P is corrected to extend straight in the front-rear direction.
このジョガー動作は、一枚の用紙Pに対して1回だけ行っても、複数回行ってもよい。
このように、位置補正作業に加え、ジョガーも行うようにすると、より一層、用紙を綺麗に揃えて積載することができる。
This jogger operation may be performed once for a single sheet of paper P or multiple times.
In this way, if the jogger is performed in addition to the position correction work, the sheets can be further aligned and stacked.
(2)増厚量が比較的少ない厚紙(用紙P)を位置補正する場合
図22は、図14に示す紙受け装置3において、比較的、増厚量が少ない厚紙(用紙P)を位置補正する場合の第2ガイド部材44−2,45−2の設定状態を示している。第2のガイド部材44−2,45−2の押圧部44b、45bの押さえ面は、第1のガイド部材44−1,44−2の上半部のガイド面と同一面に揃えられており、第1のガイド部材44−1,45−1の上半部の左右幅D3は、前記図21の左右幅D1と略同じか、少し広く設定されている。ただし、用紙Pの左右幅A1よりは短く設定されている。
(2) When correcting the position of thick paper (paper P) with a relatively small amount of increase FIG. 22 shows the position correction of thick paper (paper P) with a relatively small amount of increase in the paper receiving device 3 shown in FIG. The setting state of the 2nd guide members 44-2 and 45-2 in the case of doing is shown. The pressing surfaces of the pressing portions 44b and 45b of the second guide members 44-2 and 45-2 are aligned with the guide surfaces of the upper half portions of the first guide members 44-1 and 44-2. The left and right width D3 of the upper half of the first guide members 44-1, 45-1 is set to be substantially the same as or slightly wider than the left and right width D1 of FIG. However, it is set shorter than the left-right width A1 of the paper P.
用紙Pの位置補正をする場合は、前記図19と同様に、図22に実線で示すように、左側の第1ガイド部材44−1と第2ガイド部材44−2は、ガイド位置に固定しておき、右側の第1ガイド部材45−1と第2ガイド部材45−2を、実線で示す退避位置と仮想線で示すガイド位置との間で往復移動させることにより、用紙Pを左方に移動し、用紙幅中心線O4をU字状態中心線O3に一致させる。   When correcting the position of the paper P, the left first guide member 44-1 and the second guide member 44-2 are fixed at the guide positions as shown by the solid line in FIG. The right first guide member 45-1 and second guide member 45-2 are reciprocated between the retracted position indicated by the solid line and the guide position indicated by the phantom line, thereby moving the paper P to the left. The sheet width center line O4 is moved to coincide with the U-shaped state center line O3.
なお、厚紙の場合は、剛性が大きいので、特にジョガー動作を行わなくとも、用紙Pの左右端を揃えることができる。   In the case of thick paper, since the rigidity is high, the left and right edges of the paper P can be aligned without performing a jogger operation.
(2)増厚量が大きい厚紙(用紙P)を位置補正する場合
図23は、図22で使用する厚紙よりも、増厚量が大きい用紙Pを位置補正する場合の第2ガイド部材44−2,45−2及びU字状態保持部材42(図示せず)の設定状態を示している。
(2) When correcting the position of thick paper (paper P) having a large thickness increase FIG. 23 shows the second guide member 44-when correcting the position of the paper P having a larger thickness than the thick paper used in FIG. 2, 45-2 and the setting state of the U-shaped state holding member 42 (not shown) are shown.
第2ガイド部材44−2,45−2は、図22と同様に、それらの押圧部44b、45bの押さえ面が、第1のガイド部材44−1,44−2の上半部のガイド面と同一面に揃えられており、第1のガイド部材44−1,45−1の上半部の左右幅D3は、用紙幅A1と略同じ幅に設定されている。さらに、U字状態保持部材42(図示せず)は、紙受け台41の下側に収納されており、したがって、用紙Pはフラットな状態で紙受け台41上に保持されるようになっている。   As in FIG. 22, the second guide members 44-2 and 45-2 are such that the pressing surfaces of the pressing portions 44b and 45b are the guide surfaces of the upper half of the first guide members 44-1 and 44-2. The left and right widths D3 of the upper half portions of the first guide members 44-1, 45-1 are set to be substantially the same as the sheet width A1. Further, the U-shaped state holding member 42 (not shown) is stored below the paper receiving table 41, and therefore the paper P is held on the paper receiving table 41 in a flat state. Yes.
用紙Pの位置補正をする場合は、前記図19と同様に、図23に実線で示すように、左側の第1ガイド部材44−1と第2ガイド部材44−2は、ガイド位置に固定しておき、右側の第1ガイド部材45−1と第2ガイド部材45−2を、実線で示す退避位置と仮想線で示すガイド位置との間で往復移動させることにより、用紙Pを左方に移動し、用紙Pをフラットに保った状態で、用紙中心線O4をU字状態中心線O3に一致させる。   When correcting the position of the paper P, the left first guide member 44-1 and the second guide member 44-2 are fixed at the guide position as shown by the solid line in FIG. The right first guide member 45-1 and second guide member 45-2 are reciprocated between the retracted position indicated by the solid line and the guide position indicated by the phantom line, thereby moving the paper P to the left. In the state where the sheet P is moved and kept flat, the sheet center line O4 is made to coincide with the U-shaped state center line O3.
なお、この場合、剛性が大きいので、特にジョガー動作を行わず、かつ、U字状に曲げなくとも、用紙Pの左右端を揃えることができる。   In this case, since the rigidity is large, the left and right edges of the paper P can be aligned without performing a jogger operation and bending it into a U shape.
