Description of the Related Art A sheet post-processing apparatus that is disposed on the downstream side of an image forming apparatus and performs folding processing and binding processing on a sheet bundle on which an image is formed is known. Since the folded sheet bundle is swollen by its restoring force, the sheet bundle that has been folded is simply discharged and stacked on the discharge tray. Can not. Further, the stacking state of the sheet bundle becomes messy.
そこで、排紙トレイ上に用紙束を効率的に積載する方法として、用紙束を搬送する搬送手段を排紙トレイに設けたり、排出される用紙束の勢いを利用して、用紙束を瓦積み状に積載する用紙束積載装置が提案されている（例えば、特許文献１，２を参照）。 Therefore, as a method for efficiently stacking the sheet bundle on the sheet discharge tray, a conveying means for conveying the sheet bundle is provided on the sheet discharge tray, or the sheet bundle is stacked by using the momentum of the sheet bundle to be discharged. A sheet bundle stacking apparatus that stacks in a shape has been proposed (see, for example, Patent Documents 1 and 2).
しかしながら、前記提案の用紙束積載装置では、排紙トレイに排出された用紙束を整える手段がなく、例えば図６に示すように、排紙トレイ１１上に排出された用紙束Ｐ１の姿勢が乱れると、排紙トレイ１１上に続いて排出される用紙束Ｐ２〜Ｐ５も積載姿勢が乱れることになる。 However, in the proposed sheet bundle stacking apparatus, there is no means for adjusting the sheet bundle discharged to the sheet discharge tray, and the posture of the sheet bundle P1 discharged onto the sheet discharge tray 11 is disturbed, for example, as shown in FIG. As a result, the stacking postures of the sheet bundles P2 to P5 subsequently discharged onto the sheet discharge tray 11 are also disturbed.
本発明はこのような従来の問題に鑑みてなされたものであり、その目的は、排出時に用紙束の姿勢が乱れても用紙束の姿勢を整えることができ、排紙トレイ上に用紙束を瓦積み状に整然と積載できる用紙束積載装置及び用紙後処理装置を提供することにある。 The present invention has been made in view of such a conventional problem, and an object of the present invention is to adjust the posture of the paper bundle even when the posture of the paper bundle is disturbed at the time of discharge.

A sheet post-processing apparatus using the sheet bundle stacking apparatus according to any one of claims 1 to 3 is provided.
本発明に係る用紙束積載装置及び用紙後処理装置によれば、排出時に用紙束の姿勢が乱れても、排紙トレイ上に用紙束が瓦積み状に整然と積載される。これにより、排紙トレイの用紙束の効率的に積載できる。また、使用者が排紙トレイ上の用紙束を取り去り易くなる。 According to the sheet bundle stacking apparatus and the sheet post-processing apparatus according to the present invention, even when the posture of the sheet bundle is disturbed at the time of discharge, the sheet bundle is stacked on the sheet discharge tray in an orderly manner. Thereby, it is possible to efficiently stack the sheet bundle on the paper discharge tray. In addition, the user can easily remove the sheet bundle on the paper discharge tray.
以下、本発明に係る用紙束積載装置及び用紙後処理装置について図に基づいて詳細に説明するが、本発明はこれらの実施形態に何ら限定されるものではない。 Hereinafter, the sheet bundle stacking apparatus and the sheet post-processing apparatus according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments.
図１に、本発明に係る用紙後処理装置５及び用紙束積載装置１の一例を示す概略構成図を示す。用紙後処理装置５は画像形成装置４に接続されていて、画像形成装置４から排出される画像形成済みの用紙に対して、孔開け処理やステープルによる綴じ処理、折り処理などを行う。孔開け処理部８は搬送路５１に設けられており、綴じ処理部７及び折り処理部６は搬送路５１から分岐して下方に向かう搬送路５４に設けられている。 FIG. 1 is a schematic configuration diagram illustrating an example of a sheet post-processing apparatus 5 and a sheet bundle stacking apparatus 1 according to the present invention. The sheet post-processing device 5 is connected to the image forming device 4 and performs punching processing, stapling processing, folding processing, and the like on the image-formed paper discharged from the image forming device 4. The punching processing unit 8 is provided in the conveyance path 51, and the binding processing unit 7 and the folding processing unit 6 are provided in the conveyance path 54 branched from the conveyance path 51 and directed downward.
画像形成装置４から排出された用紙は、用紙後処理装置５の搬送路５１に搬入され、綴じ処理や折り処理を行わない場合には、搬送路５２を通って第１排紙トレイ５３に排出される。一方、綴じ処理や折り処理を行う場合には、搬送路５１から搬送路５４へ搬送される。いずれの場合にも、必要により、孔開け処理部８によって用紙に孔が開けられる。 The sheet discharged from the image forming apparatus 4 is carried into the conveyance path 51 of the sheet post-processing apparatus 5, and is discharged to the first discharge tray 53 through the conveyance path 52 when the binding process and the folding process are not performed. Is done. On the other hand, when the binding process or the folding process is performed, the sheet is conveyed from the conveyance path 51 to the conveyance path 54. In either case, a hole is formed in the sheet by the hole punching processing unit 8 as necessary.
搬送路５４に搬送された用紙は集積トレイ６２に集積される。集積トレイ６２の下端には、集積された用紙束の下端位置を位置決めすると共に用紙束を挟持し集積トレイ６２内を移動させる先端位置決め具６３が配置されている。 The sheets conveyed to the conveyance path 54 are accumulated on the accumulation tray 62. At the lower end of the stacking tray 62, a leading end positioning tool 63 for positioning the lower end position of the stacked sheet bundle and sandwiching the sheet bundle and moving in the stacking tray 62 is disposed.
集積トレイ６２の上部には、ステープルによって用紙束を綴じる綴じ処理部７が配置されている。用紙束の綴じ位置は使用者によって指定され、先端位置決め具６３によって用紙束が集積トレイ６２内を上下移動することによって調整される。 A binding processing unit 7 that binds a bundle of sheets with staples is disposed on the upper side of the stacking tray 62. The binding position of the sheet bundle is designated by the user, and the sheet bundle is adjusted by the tip positioning tool 63 as the sheet bundle moves up and down in the stacking tray 62.
集積トレイ６２の上下方向略中央部の一方の側面近傍には、用紙を折り処理するための一対の折りローラ対６６が配置され、集積トレイ６２を挟んで折りローラ対６６と向かい合う位置には折りナイフ６５が配置されている。 A pair of folding roller pairs 66 for folding the paper is disposed near one side surface of the central portion of the stacking tray 62 in the vertical direction, and is folded at a position facing the folding roller pair 66 across the stacking tray 62. A knife 65 is arranged.
図２に、用紙束Ｐの中央部をステープルで綴じた後、当該中央部で折り処理する場合の工程図を示す。まず、図２（ａ）に示すように、集積トレイ６２に一揃えの用紙束Ｐが集積されると、用紙束Ｐの下端が先端位置決め具６３によって挟持され、用紙束Ｐの中央部が綴じ処理部７に位置するように用紙束Ｐは上方へ移動される。そして、用紙束Ｐの中央部が綴じ処理部７によって綴じられる。 FIG. 2 shows a process chart in the case where the central portion of the sheet bundle P is stapled and then folded at the central portion. First, as shown in FIG. 2A, when the aligned sheet bundle P is stacked on the stacking tray 62, the lower end of the sheet bundle P is sandwiched by the leading edge positioning tool 63, and the central portion of the sheet bundle P is bound. The sheet bundle P is moved upward so as to be positioned in the processing unit 7. Then, the center portion of the sheet bundle P is bound by the binding processing unit 7.
次いで同図（ｂ）に示すように、先端位置決め具６３によって用紙束Ｐの綴じられた中央部が折りナイフ６５と対向する位置に移動される。そして、折りナイフ６５が集積トレイ６２内に突出するとともに、折りローラ対６６が回転開始し、用紙束Ｐの中央部が折りローラ対６６に挟み込まれる。折りナイフ６５は用紙束Ｐが折りローラ対６６に挟み込まれたところで元の位置に戻る。用紙束Ｐは、折りローラ対６６によって挟持加圧されることによって中折り状態となる。用紙束Ｐの先端が排紙検知センサＳ２によって検知されると、排紙ローラ対６７が回転を開始し、同図（ｃ）のように、排紙ローラ対６７によって用紙束Ｐは用紙束積載装置１（図１に図示）に排出される。この一連の動作が、用紙束Ｐが、使用者が入力した部数となるまで繰り返し行われる。 Next, as shown in FIG. 5B, the center portion where the sheet bundle P is bound is moved to a position facing the folding knife 65 by the tip positioning tool 63. Then, the folding knife 65 protrudes into the stacking tray 62, the folding roller pair 66 starts to rotate, and the central portion of the sheet bundle P is sandwiched between the folding roller pair 66. The folding knife 65 returns to the original position when the sheet bundle P is sandwiched between the folding roller pair 66. When the sheet bundle P is nipped and pressed by the pair of folding rollers 66, the sheet bundle P is in a middle folded state. When the leading end of the sheet bundle P is detected by the sheet discharge detection sensor S2, the sheet discharge roller pair 67 starts rotating, and the sheet bundle P is loaded by the sheet discharge roller pair 67 as shown in FIG. It is discharged into the device 1 (shown in FIG. 1). This series of operations is repeated until the sheet bundle P reaches the number of copies input by the user.
なお、以上説明した折り処理は、用紙束Ｐの中央部をステープルで綴じた後、当該中央部で折り処理する中折り処理であったが、本発明における折り処理は、これに限定されるものではなく、三つ折り処理や四つ折り処理などであってももちろん構わない。ただし、三つ折りや四つ折りなどの折り処理をする場合には、折りローラ対を増設する必要がある。 The folding process described above is an intermediate folding process in which the central part of the sheet bundle P is stapled and then folded at the central part. However, the folding process in the present invention is limited to this. Of course, it does not matter even if it is a tri-fold process or a four-fold process. However, when folding processing such as tri-folding or quadruple folding is performed, it is necessary to add a pair of folding rollers.
次に、図３及び図４を用いて用紙束積載装置１について以下説明する。図３は、用紙束積載装置１の垂直断面図であり、図４は、用紙束積載装置の斜視図である。用紙束積載装置１は、折り処理された用紙束Ｐを積載する排紙トレイ１１と、排紙トレイ１１上に排出された用紙束Ｐを略水平方向に搬送する搬送手段１２と、排紙トレイ１１の、用紙束排出方向上流側に設けられた、排出された用紙束Ｓの積載姿勢を整える整合部材１３と、排紙トレイ１１上の積載された用紙束Ｓを押圧する押さえ部材１４とを有する。 Next, the sheet bundle stacking apparatus 1 will be described below with reference to FIGS. 3 and 4. 3 is a vertical sectional view of the sheet bundle stacking apparatus 1, and FIG. 4 is a perspective view of the sheet bundle stacking apparatus. The paper bundle stacking apparatus 1 includes a paper discharge tray 11 on which the folded paper bundle P is stacked, a transport unit 12 that transports the paper bundle P discharged onto the paper discharge tray 11 in a substantially horizontal direction, and a paper discharge tray. 11, an alignment member 13 provided on the upstream side in the sheet bundle discharge direction for adjusting the stacking posture of the discharged sheet bundle S, and a pressing member 14 for pressing the stacked sheet bundle S on the discharge tray 11. Have.
排紙トレイ１１には、排出ローラ対６７から排出された用紙束Ｓが着地する部分に用紙束Ｓがあるかどうかを検知するセンサーＳ１が設けられている。このセンサーＳ１から出力される信号に基づいて用紙束積載装置１の動作が制御される。動作制御内容は後述する。 The paper discharge tray 11 is provided with a sensor S <b> 1 that detects whether or not the paper bundle S is in a portion where the paper bundle S discharged from the discharge roller pair 67 lands. The operation of the sheet stacking device 1 is controlled based on the signal output from the sensor S1. The details of the operation control will be described later.
搬送手段１２は、排紙トレイ１１に内設されており、ローラー１２２ａと、ローラー１２２ｂと、これらのローラー間に張架され回転自在の搬送ベルト１２１と、ローラー１２２ａを回転させるモーターＭとを有する。搬送ベルト１２１は用紙束排出方向に対して垂直方向（以下、「幅方向」と記すことがある）に所定間隔隔てて２つ設けられている。排出ローラ対６７から排出された用紙束Ｐは、搬送ベルト１２１によって排紙トレイ１１上を用紙束排出方向上流側及び下流側に搬送される。 The conveying means 12 is provided in the paper discharge tray 11, and includes a roller 122a, a roller 122b, a rotatable conveying belt 121 stretched between these rollers, and a motor M that rotates the roller 122a. . Two conveying belts 121 are provided at a predetermined interval in a direction perpendicular to the sheet bundle discharging direction (hereinafter, also referred to as “width direction”). The sheet bundle P discharged from the discharge roller pair 67 is conveyed on the sheet discharge tray 11 to the upstream side and the downstream side in the sheet bundle discharge direction by the conveyance belt 121.
整合部材１３は、断面Ｌ字の棒状部材からなり、用紙束排出方向及び排紙トレイ１１の積載面に対して垂直な当接面１３１を有している。整合部材１３は、幅方向に所定間隔隔てて２つ設けられている。もちろ幅方向全体にわたる長さの整合部材１３を１つ設けても構わない。また、用紙束の幅方向両端を整える整合部材をさらに設けても構わない。 The alignment member 13 is a bar-shaped member having an L-shaped cross section, and has a contact surface 131 that is perpendicular to the sheet bundle discharge direction and the stacking surface of the sheet discharge tray 11. Two alignment members 13 are provided at a predetermined interval in the width direction. Needless to say, one alignment member 13 having a length over the entire width direction may be provided. Further, an alignment member for adjusting both ends in the width direction of the sheet bundle may be further provided.
押さえ手段１４は、長手部１４１ａと短手部１４１ｂとが「Ｌ」字状に一体成形された棒状部材１４１と、棒状部材１４１の屈曲部に回転自在に設けられたコロ１４２とを有し、幅方向に所定間隔を隔てて２つ設けられている。棒状部材１４１の長手部の端部が用紙後処理装置５の本体に揺動自在に軸支され、押さえ手段１４の自重によってコロ１４２が搬送ベルト１２１に当接している。コロ１４２は、搬送ベルト１２１の回転によって従動回転する。 The holding means 14 includes a rod-shaped member 141 in which a long portion 141 a and a short portion 141 b are integrally formed in an “L” shape, and a roller 142 that is rotatably provided at a bent portion of the rod-shaped member 141. Two are provided at predetermined intervals in the width direction. The end of the longitudinal portion of the rod-shaped member 141 is pivotally supported by the main body of the paper post-processing apparatus 5, and the roller 142 is in contact with the transport belt 121 by the weight of the pressing means 14. The roller 142 is rotated by the rotation of the conveyor belt 121.
本発明に係る用紙束積載装置１の大きな特徴は、排紙トレイ１１に排出された用紙束Ｐを、搬送ベルト１２１によって用紙束排出方向上流側に移動させて整合部材１３に当接させて用紙束Ｐの積載姿勢を整えることにある。 The major feature of the sheet bundle stacking apparatus 1 according to the present invention is that the sheet bundle P discharged to the sheet discharge tray 11 is moved to the upstream side in the sheet bundle discharge direction by the conveyor belt 121 and brought into contact with the alignment member 13 to form the sheet. It is to arrange the stacking posture of the bundle P.
図５に、排紙トレイ１１に用紙束Ｐが連続して排出され積載される工程図を示す。折り処理された用紙束Ｐ１が排紙トレイ１１に排出されると、センサーＳ１によって用紙束Ｐ１の排出が検知される（図５（ａ））。すると、モーターＭが起動して搬送ベルト１２１が時計回りに回転し、用紙束Ｐ１は用紙束排出方向上流側に搬送される。そして、用紙束Ｐ１の用紙排出方向後端が整合部材１３の当接面１３１に当接する（同図（ｂ））。これにより、用紙束Ｐ１の積載姿勢が整えられる。 FIG. 5 is a process diagram in which the sheet bundle P is continuously discharged and stacked on the discharge tray 11. When the folded sheet bundle P1 is discharged to the sheet discharge tray 11, the discharge of the sheet bundle P1 is detected by the sensor S1 (FIG. 5A). Then, the motor M is activated and the conveying belt 121 rotates clockwise, and the sheet bundle P1 is conveyed upstream in the sheet bundle discharging direction. Then, the rear end of the sheet bundle P1 in the sheet discharge direction comes into contact with the contact surface 131 of the alignment member 13 ((b) in the figure). Thereby, the stacking posture of the sheet bundle P1 is adjusted.
ここで、用紙束Ｐ１を用紙束排出方向上流側に搬送する距離は、用紙束Ｐ１の種類によって変化させるのが好ましい。すなわち、用紙束Ｐ１を構成する用紙の斤量やサイズが大きいほど、また用紙束Ｐ１を構成する用紙枚数が多いほど、用紙束はＰ１排紙トレイ１１上の排出ローラ対６７から近い位置に着地し、用紙束Ｐ１の用紙束排出方向後端と整合部材１３との距離Ｌ１は短くなるので、用紙束Ｐ１を用紙束排出方向上流側に搬送する距離は短くてもよい。ただし、整合部材１３に用紙束Ｐ１を当接させる必要があるので、用紙束Ｐ１の搬送距離は距離Ｌ１より長くなければならない。用紙束Ｐ１の搬送距離の具体例を表１に示す。 Here, it is preferable that the distance for transporting the sheet bundle P1 upstream in the sheet bundle discharge direction is changed according to the type of the sheet bundle P1. In other words, the larger the amount and size of the sheets constituting the sheet bundle P1 and the larger the number of sheets constituting the sheet bundle P1, the closer the sheet bundle to the position closer to the discharge roller pair 67 on the P1 sheet discharge tray 11. Since the distance L1 between the rear end of the sheet bundle P1 in the sheet bundle discharge direction and the alignment member 13 is shortened, the distance for conveying the sheet bundle P1 upstream in the sheet bundle discharge direction may be short. However, since it is necessary to bring the sheet bundle P1 into contact with the alignment member 13, the conveyance distance of the sheet bundle P1 must be longer than the distance L1. Table 1 shows specific examples of the transport distance of the sheet bundle P1.
整合部材１３によって用紙束Ｐ１の積載姿勢が整えられると、搬送ベルト１２１が反時計回りに回転し、用紙束Ｐ１の用紙束排出方向先端と用紙束排出方向後端との間に、次に排出される用紙束Ｐ２の用紙束排出方向先端が位置するように、用紙束Ｐ１は用紙束搬送方向下流側に搬送される（図５（ｃ））。次いで、排出ローラ対６７から次の用紙束Ｐ２が排紙トレイ１１に排出される。用紙束Ｐ２は、その用紙束排出方向先端が用紙束Ｐ１の用紙束排出方向先端から距離Ｌ２上流側にずれた位置に積載される（図５（ｄ））。なお、用紙束Ｐ２の排紙トレイ１１への排出は、用紙束Ｐ１の前記位置への搬送後であってもよいし、用紙束Ｐ１の前記位置への搬送と同時であってもよい。後者の場合、用紙束Ｐ２の排紙トレイ１１への着地は、センサーＳ２の出力信号に基づいて行えばよい。用紙束Ｐ１と用紙束Ｐ２とのずれ距離Ｌ２に特に限定はない。排紙トレイ１１の用紙束Ｐの積載量を多くするためには短くするのが好ましく、積載された用紙束Ｐを個々に分けやすくするためには長くするのが好ましい。通常、距離Ｌ２は１０ｍｍ〜２０ｍｍの範囲が好ましい。 When the stacking posture of the sheet bundle P1 is adjusted by the aligning member 13, the conveying belt 121 rotates counterclockwise, and the sheet bundle P1 is next discharged between the front end of the sheet bundle discharge direction and the rear end of the sheet bundle discharge direction. The sheet bundle P1 is conveyed downstream in the sheet bundle conveyance direction so that the leading end of the sheet bundle P2 in the sheet bundle discharge direction is positioned (FIG. 5C). Next, the next sheet bundle P <b> 2 is discharged from the discharge roller pair 67 to the discharge tray 11. The sheet bundle P2 is stacked at a position where the leading end in the sheet bundle discharging direction is shifted to the upstream side of the distance L2 from the leading end in the sheet bundle discharging direction of the sheet bundle P1 (FIG. 5D). The discharge of the sheet bundle P2 to the sheet discharge tray 11 may be performed after the conveyance of the sheet bundle P1 to the position or at the same time as the conveyance of the sheet bundle P1 to the position. In the latter case, the landing of the sheet bundle P2 on the paper discharge tray 11 may be performed based on the output signal of the sensor S2. There is no particular limitation on the deviation distance L2 between the sheet bundle P1 and the sheet bundle P2. In order to increase the stacking amount of the sheet bundle P on the discharge tray 11, it is preferable to shorten the stacking amount, and in order to easily separate the stacked sheet bundles P, it is preferable to increase the stacking amount. Usually, the distance L2 is preferably in the range of 10 mm to 20 mm.
そして、用紙束Ｐ２に対しても、図５（ａ）〜（ｃ）に示した動作が行われ、用紙束Ｐ２は積載姿勢が整えられた後、次の用紙束の受け入れ位置に搬送される。このような動作が、所定部数の用紙束が排出されるまで繰り返され、一連の用紙束は排紙トレイ１１上に瓦積み状に整然と積載される The operations shown in FIGS. 5A to 5C are also performed on the sheet bundle P2, and the sheet bundle P2 is transported to the receiving position of the next sheet bundle after the stacking posture is adjusted. . Such an operation is repeated until a predetermined number of sheet bundles are discharged, and the series of sheet bundles are stacked on the sheet discharge tray 11 in a tiled manner.
本発明に係る用紙束積載装置及び用紙後処理装置は、排出時に用紙束の積載姿勢が乱れても、排紙トレイ上に用紙束を瓦積み状に整然と積載でき有用である。 The sheet bundle stacking apparatus and the sheet post-processing apparatus according to the present invention are useful because they can stack the sheet bundle on the sheet discharge tray in an orderly manner even when the stacking posture of the sheet bundle is disturbed at the time of discharge.
