Description

本発明は、用紙処理装置に関する。   The present invention relates to a sheet processing apparatus.

従来から、複写機や複合機（ＭＦＰ：Multifunction Peripheral）などの画像形成装置から排出された用紙に対して、ステイプル（綴じ）処理などの後処理を行う用紙処理装置が知られている。   2. Description of the Related Art Conventionally, a paper processing apparatus that performs post-processing such as stapling (binding) processing on paper discharged from an image forming apparatus such as a copying machine or a multifunction peripheral (MFP) is known.

このような用紙処理装置は、画像形成装置から排出された用紙がステイプルトレイにスタックされる毎に、用紙の搬送方向及び用紙の幅方向に対して揃え動作を行い、用紙束を整合した後にステイプル処理を行う。   Such a paper processing apparatus performs an aligning operation in the paper transport direction and the paper width direction each time the paper discharged from the image forming apparatus is stacked on the staple tray, aligns the paper bundle, and then staples the paper. Process.

ところで、Ｚ折り処理（外三折り処理）など折り処理が施された用紙は、折り部が復元力によって元の状態に戻ろうとするため、ステイプルトレイにスタックした場合に膨らみ易いという問題がある。   By the way, a sheet subjected to folding processing such as Z-folding processing (outer three-folding processing) tends to swell when it is stacked on a staple tray because the folded portion tends to return to its original state by a restoring force.

このため、例えば特許文献１には、シート処理装置に用紙束の膨らみを押さえる押え込みロールを設け、ステイプル処理を行う枚数分の用紙がコンパイルトレイに積載されると、コンパイルトレイに積載された用紙束を押え込みロールで押さえ、その後にステイプル処理を行う技術が開示されている。   For this reason, for example, in Patent Document 1, when the sheet processing apparatus is provided with a pressing roll for suppressing the swelling of the sheet bundle, and the number of sheets to be stapled are stacked on the compile tray, the sheet bundle stacked on the compile tray. A technique is disclosed in which a pressing roll is pressed and then a stapling process is performed.

特許文献１に開示された技術によれば、コンパイルトレイに積載された用紙束の膨らみに伴い、用紙揃えが乱れた状態でステイプル処理が行われてしまうことを防止することができる。   According to the technique disclosed in Patent Document 1, it is possible to prevent the stapling process from being performed in a state where the sheet alignment is disturbed with the expansion of the sheet bundle loaded on the compile tray.

以下、添付図面を参照しながら、本発明にかかる用紙処理装置の実施形態を詳細に説明する。   Hereinafter, embodiments of a sheet processing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

まず、図１〜図４を参照しながら、用紙処理装置の構成について説明する。   First, the configuration of the sheet processing apparatus will be described with reference to FIGS.

図１は、本実施形態の用紙処理装置１の一例を示す構成図である。図１に示すように、画像形成装置などの本体装置６と接続された用紙処理装置１は、折り処理部２、用紙搬送路３、ステイプル処理部４、及び排紙トレイ５などを備える。   FIG. 1 is a configuration diagram illustrating an example of a sheet processing apparatus 1 according to the present embodiment. As shown in FIG. 1, a paper processing apparatus 1 connected to a main body device 6 such as an image forming apparatus includes a folding processing unit 2, a paper conveyance path 3, a stapling processing unit 4, a paper discharge tray 5, and the like.

本体装置６により画像が形成（印刷）された用紙に折り処理やステイプル（綴じ）処理を施すモードでは、本体装置６から画像が形成された用紙が用紙処理装置１の折り処理部２に送られる。   In a mode in which folding processing or stapling processing is performed on a sheet on which an image is formed (printed) by the main body device 6, the paper on which the image is formed is sent from the main body device 6 to the folding processing unit 2 of the paper processing apparatus 1. .

折り処理部２は、本体装置６から送られてきた用紙に対して、山折り処理、谷折り処理、Ｚ折り処理（外三折り処理）、又はＣ折り処理（内三折り処理）など各種折り処理を施す。   The fold processing unit 2 performs various folds such as a mountain fold process, a valley fold process, a Z fold process (an outer tri-fold process), or a C fold process (an inner tri-fold process) on the paper sent from the main body device 6. Apply processing.

用紙搬送路３は、折り処理部２により折り処理が施された用紙を搬送し、ステイプル処理部４へ送る。   The paper transport path 3 transports the paper that has been subjected to the folding processing by the folding processing unit 2 and sends it to the stapling processing unit 4.

ステイプル処理部４は、用紙搬送路３から送られてきた用紙に対して、ステイプル処理を施す。ステイプル処理部４の詳細については、後述する。   The staple processing unit 4 performs a stapling process on the paper sent from the paper transport path 3. Details of the staple processing unit 4 will be described later.

排紙トレイ５には、ステイプル処理部４によりステイプル処理が施された用紙束が排紙される。   A sheet bundle subjected to the staple processing by the staple processing unit 4 is discharged to the paper discharge tray 5.

図２は、本実施形態のステイプル処理部４の構成の一例を示す斜視図である。図３は、本実施形態のステイプル処理部４の構成の一例を示す左側面図である。図２及び図３に示すように、ステイプル処理部４は、飛び出し防止部材９ａ、ｂ、押さえ部材１０ａ、ｂ、ステイプルトレイ１１、叩きコロ１２、後端フェンス１３ａ、ｂ、ジョガーフェンス１４ａ、ｂ、ステイプルユニット１５、及び弾性部材２０ａ、ｂなどを備える。   FIG. 2 is a perspective view showing an example of the configuration of the staple processing unit 4 of the present embodiment. FIG. 3 is a left side view illustrating an example of the configuration of the staple processing unit 4 of the present embodiment. As shown in FIGS. 2 and 3, the staple processing unit 4 includes pop-out prevention members 9a and 9b, pressing members 10a and 10b, staple tray 11, hitting roller 12, rear end fences 13a and 13b, jogger fences 14a and 14b, A staple unit 15 and elastic members 20a and 20b are provided.

ステイプルトレイ１１（トレイの一例）は、用紙搬送路３から搬送されてくる用紙を順次スタックする。ステイプルトレイ１１には、飛び出し防止部材９ａ及び押さえ部材１０ａが移動可能な移動孔１１ａとともに、飛び出し防止部材９ｂ及び押さえ部材１０ｂが移動可能な移動孔１１ｂが設けられている。移動孔１１ａ、ｂは、ステイプルトレイ１１の搬送方向に設けられている。   A staple tray 11 (an example of a tray) sequentially stacks sheets conveyed from the sheet conveyance path 3. The staple tray 11 is provided with a movement hole 11a through which the pop-out prevention member 9a and the pressing member 10a can move, and a movement hole 11b through which the pop-out prevention member 9b and the pressing member 10b can move. The moving holes 11 a and 11 b are provided in the conveyance direction of the staple tray 11.

飛び出し防止部材９ａ、ｂは、ステイプルトレイ１１に搬送された用紙のステイプルトレイ１１からの飛び出しを防止する。飛び出し防止部材９ａ、ｂは、それぞれ、後述の押さえ部材１０ａ、ｂとともに、用紙搬送方向及びその逆方向、並びに用紙押さえ方向及びその逆方向（ステイプルトレイ１１と直交する方向）に移動可能に構成されている（図３の矢印参照）。   The pop-out prevention members 9 a and 9 b prevent the paper conveyed to the staple tray 11 from jumping out from the staple tray 11. The pop-out prevention members 9a and 9b are configured to be movable in the paper transport direction and its reverse direction, and the paper press direction and its reverse direction (a direction orthogonal to the staple tray 11) together with the press members 10a and b described later. (See arrow in FIG. 3).

後端フェンス１３ａ、ｂは、ステイプルトレイ１１の用紙搬送方向後端部に設けられている。   The rear end fences 13 a and 13 b are provided at the rear end of the staple tray 11 in the sheet conveyance direction.

叩きコロ１２（戻し部材の一例）は、ステイプルトレイ１１に用紙が搬送される毎に、搬送された用紙を戻し、用紙の後端を後端フェンス１３ａ、ｂへ突き立てる。具体的には、叩きコロ１２は、図示せぬソレノイドなどの駆動源のオン、オフに伴って振り子運動を行うことにより（図２の叩きコロ１２の矢印参照）、ステイプルトレイ１１に搬送された用紙を叩き、搬送された用紙を搬送方向と逆方向（下方向）に戻し、用紙の後端を後端フェンス１３ａ、ｂへ突き立てる。これにより、用紙の搬送方向が揃えられる。   The tapping roller 12 (an example of a return member) returns the conveyed sheet every time the sheet is conveyed to the staple tray 11 and pushes the rear end of the sheet toward the rear end fences 13a and 13b. Specifically, the hitting roller 12 is transported to the staple tray 11 by performing a pendulum motion as a driving source such as a solenoid (not shown) is turned on and off (see the arrow of the hitting roller 12 in FIG. 2). The sheet is struck, the conveyed sheet is returned in the direction opposite to the conveyance direction (downward), and the rear end of the sheet is pushed up to the rear end fences 13a and 13b. Thereby, the conveyance direction of the paper is aligned.

ジョガーフェンス１４ａ、ｂは、後端フェンス１３ａ、ｂへ突き立てられている用紙の幅方向を揃える。具体的には、ジョガーフェンス１４ａ、ｂそれぞれは、図示せぬモータ及びベルトなどの駆動源により、用紙の幅方向にスライド運動を行う（図２のジョガーフェンス１４ａ、ｂの矢印参照）。これにより、用紙の幅方向が揃えられる。   The jogger fences 14a, 14b align the width direction of the paper protruding to the rear end fences 13a, 13b. Specifically, each of the jogger fences 14a and 14b performs a sliding motion in the sheet width direction by a driving source such as a motor and a belt (not shown) (see arrows of the jogger fences 14a and 14b in FIG. 2). Thereby, the width direction of the paper is aligned.

押さえ部材１０ａ、ｂは、後端フェンス１３ａ、ｂへ用紙が突き立てられる毎に、突き立てられている用紙をステイプルトレイ１１に押さえつける。押さえ部材１０ａ、ｂの動作については後述する。押さえ部材１０ａ、ｂは、それぞれ飛び出し防止部材９ａ、ｂにより支持されている。   The pressing members 10a and 10b press the pushed paper against the staple tray 11 every time the paper is pushed to the rear end fences 13a and 13b. The operation of the pressing members 10a and 10b will be described later. The pressing members 10a and 10b are supported by the pop-out preventing members 9a and 9b, respectively.

弾性部材２０ａ、ｂは、それぞれ、押さえ部材１０ａと飛び出し防止部材９ａとの結合部、押さえ部材１０ｂと飛び出し防止部材９ｂとの結合部に用いられている。弾性部材２０ａ、ｂは、例えば、ばね機構などにより実現できる。   The elastic members 20a and 20b are used at the connecting portion between the pressing member 10a and the pop-out preventing member 9a and at the connecting portion between the pressing member 10b and the pop-out preventing member 9b, respectively. The elastic members 20a and 20b can be realized by a spring mechanism or the like, for example.

ステイプルユニット１５は、後端フェンス１３ａ、ｂへ突き立てられている用紙束が押さえ部材１０ａ、ｂによりステイプルトレイ１１に押さえつけられた状態でステイプル（綴じ）を行う。そして、ステイプルが行われた用紙束は、ステイプル処理部４に備えられている図示せぬ放出機構により排紙トレイ５に放出される。   The staple unit 15 performs the stapling (binding) in a state where the sheet bundle protruding to the rear end fences 13a and 13b is pressed against the staple tray 11 by the pressing members 10a and 10b. Then, the sheet bundle subjected to the stapling is discharged to the paper discharge tray 5 by a discharge mechanism (not shown) provided in the staple processing unit 4.

図４は、本実施形態の飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂの駆動機構の一例を示す斜視図である。図４に示すように、駆動機構は、搬送ベルト２１と、ステッピングモータ２２と、ソレノイド２３と、ガイド部材２４と、固定部材２５とを、備える。なお、駆動機構は、ステイプルトレイ１１の用紙スタック面の反対面側に位置する。   FIG. 4 is a perspective view showing an example of a drive mechanism for the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b according to the present embodiment. As shown in FIG. 4, the drive mechanism includes a conveyance belt 21, a stepping motor 22, a solenoid 23, a guide member 24, and a fixing member 25. The drive mechanism is located on the opposite side of the paper stack surface of the staple tray 11.

固定部材２５は、飛び出し防止部材９ａ及び９ｂを固定する。詳細には、固定部材２５は、飛び出し防止部材９ａ及び９ｂを用紙搬送方向及びその逆方向に対して固定する。   The fixing member 25 fixes the pop-out preventing members 9a and 9b. Specifically, the fixing member 25 fixes the pop-out prevention members 9a and 9b in the paper transport direction and the opposite direction.

ガイド部材２４は、飛び出し防止部材９ａ、ｂの用紙搬送方向及びその逆方向の移動をガイドする。   The guide member 24 guides the movement of the pop-out prevention members 9a and 9b in the paper transport direction and in the opposite direction.

ステッピングモータ２２の回転軸には、搬送ベルト２１が巻回されている。ステッピングモータ２２は、回転軸を回転させることにより搬送ベルト２１を無端移動させる。   A conveyor belt 21 is wound around the rotation shaft of the stepping motor 22. The stepping motor 22 moves the conveyor belt 21 endlessly by rotating the rotating shaft.

搬送ベルト２１は、ステッピングモータ２２の回転軸に巻回されているとともに、固定部材２５が固定されている。このため、ステッピングモータ２２の回転軸が正回転又は逆回転することにより、飛び出し防止部材９ａ、ｂがガイド部材２４によりガイドされながら、搬送ベルト２１、固定部材２５、及び飛び出し防止部材９ａ、ｂが一体となって用紙搬送方向又はその逆方向に移動する。これにより、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂの用紙搬送方向及びその逆方向への移動が実現される。   The conveyor belt 21 is wound around the rotation shaft of the stepping motor 22 and the fixing member 25 is fixed. For this reason, when the rotation shaft of the stepping motor 22 rotates forward or backward, the pop-out preventing members 9a and 9b are guided by the guide member 24, while the transport belt 21, the fixing member 25, and the pop-out preventing members 9a and 9b are They move together in the paper transport direction or in the opposite direction. Thereby, the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are moved in the paper transport direction and in the opposite direction.

ソレノイド２３は、ガイド部材２４を用紙押さえ方向又はその逆方向に移動させる。これにより、飛び出し防止部材９ａ、ｂがガイド部材２４と一体となって用紙押さえ方向又はその逆方向に移動し、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂの用紙押さえ方向又はその逆方向への移動が実現される。   The solenoid 23 moves the guide member 24 in the sheet pressing direction or the opposite direction. As a result, the pop-out preventing members 9a and 9b move integrally with the guide member 24 in the paper pressing direction or the opposite direction, and the pop-out preventing member 9a and the pressing member 10a, and the paper pressing of the pop-out preventing member 9b and the pressing member 10b. Movement in the direction or vice versa is realized.

なお、固定部材２５は、飛び出し防止部材９ａ及び９ｂを用紙押さえ方向及びその逆方向には固定していないため、ガイド部材２４を用紙押さえ方向及びその逆方向に移動しても、固定部材２５、搬送ベルト２１、及びステッピングモータ２２は用紙押さえ方向及びその逆方向には移動しない。   The fixing member 25 does not fix the pop-out prevention members 9a and 9b in the paper pressing direction and the opposite direction. Therefore, even if the guide member 24 is moved in the paper pressing direction and the reverse direction, the fixing member 25, The conveyor belt 21 and the stepping motor 22 do not move in the sheet pressing direction and in the opposite direction.

次に、図５〜図１２を参照しながら、用紙処理装置の動作について説明する。ここでは、折り処理部２により山折り処理が施された２枚の山折り用紙をステイプルする場合を例に取り説明する。   Next, the operation of the sheet processing apparatus will be described with reference to FIGS. Here, a case will be described as an example where two fold-folded sheets that have been subjected to the fold-folding process by the folding processing unit 2 are stapled.

図５は、本実施形態の用紙処理装置１において、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂがホームポジションに位置する状態の一例を示す斜視図である。飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、図５に示すように、飛び出し防止部材９ａ、ｂがそれぞれ移動孔１１ａ、ｂの用紙搬送方向前方に位置するとともに押さえ部材１０ａ、ｂがそれぞれ移動孔１１ａ、ｂ内に位置するホームポジションから、動作を開始する。   FIG. 5 is a perspective view illustrating an example of a state in which the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are located at the home position in the paper processing apparatus 1 according to the present embodiment. As shown in FIG. 5, the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are pressed while the pop-out preventing members 9a and 9b are respectively positioned in front of the movement holes 11a and b in the sheet conveying direction. The operation starts from the home positions where the members 10a and 10b are located in the movement holes 11a and 11b, respectively.

図６は、本実施形態の用紙処理装置１において、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂが飛出防止ポジションに移動した状態の一例を示す斜視図である。飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、図６に示すように、１枚目の山折り用紙Ｐ１がステイプルトレイ１１に搬送されてくると（図６の用紙Ｐ１の矢印参照）、ホームポジションから、飛び出し防止部材９ａ、ｂがそれぞれ移動孔１１ａ、ｂの用紙搬送方向前方に位置するとともに押さえ部材１０ａ、ｂがステイプルトレイ１１の用紙スタック面側に位置する飛出防止ポジションに移動する（図６の飛び出し防止部材９ａの矢印参照）。   FIG. 6 is a perspective view illustrating an example of a state in which the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are moved to the pop-out preventing position in the paper processing apparatus 1 according to the present embodiment. As shown in FIG. 6, the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are transported to the staple tray 11 as shown in FIG. From the home position, the pop-out prevention members 9a and 9b are located in front of the movement holes 11a and b in the paper transport direction, and the holding members 10a and 10b are located on the paper stack surface side of the staple tray 11, respectively. It moves to the protrusion prevention position (see the arrow of the pop-out prevention member 9a in FIG. 6).

具体的には、図示せぬセンサによりステイプルトレイ１１に用紙Ｐ１が搬送されたことが検知されると、図示せぬ制御装置によりソレノイド２３が駆動される。これにより、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、用紙押さえ方向と逆方向に移動し、ホームポジションから飛出防止ポジションに移動する。   Specifically, when it is detected by a sensor (not shown) that the paper P1 has been conveyed to the staple tray 11, the solenoid 23 is driven by a control device (not shown). Thereby, the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b move in the direction opposite to the paper pressing direction, and move from the home position to the pop-out preventing position.

なお、飛出防止ポジションは、ステイプルトレイ１１に搬送された用紙の飛出を防止できる位置、即ち、ステイプルトレイ１１に搬送された用紙が押さえ部材１０ａ、ｂを乗り越えてしまうことを防止できる位置であればよい。従って、ステイプルトレイ１１にスタックされている用紙の枚数に応じて飛出防止ポジションを異ならせてもよい。例えば、ステイプルトレイ１１にスタックされている用紙の枚数が増えるほど、ステイプルトレイ１１から離れた位置に飛出防止ポジションを設定するようにしてもよい。このようにすれば、ステイプルトレイに搬送された用紙のステイプルトレイからの飛び出しをより効果的に防止することができる。   The pop-out prevention position is a position where the paper conveyed to the staple tray 11 can be prevented from jumping out, that is, a position where the paper conveyed to the staple tray 11 can be prevented from getting over the pressing members 10a and 10b. I just need it. Therefore, the pop-out prevention position may be varied depending on the number of sheets stacked on the staple tray 11. For example, the jump prevention position may be set at a position farther from the staple tray 11 as the number of sheets stacked on the staple tray 11 increases. In this way, it is possible to more effectively prevent the paper conveyed to the staple tray from jumping out of the staple tray.

また、飛出防止ポジションは、用紙サイズや用紙に施された折り処理に応じて異ならせるようにしてもよい。このようにすれば、新たにステイプルトレイにスタックされる用紙のスタック不良をより低減することができる。   Further, the pop-out prevention position may be made different depending on the paper size and the folding process applied to the paper. In this way, it is possible to further reduce the stacking failure of sheets newly stacked on the staple tray.

図７は、本実施形態の用紙処理装置１における叩きコロ１２による用紙Ｐ１の搬送方向での揃え動作の一例を示す斜視図である。ステイプルトレイ１１に搬送された用紙Ｐ１が飛び出し防止部材９ａ、ｂにぶつかり、ステイプルトレイ１１にスタックされると、図７に示すように、スタックされた用紙Ｐ１を叩きコロ１２が叩き（図７の叩きコロ１２の矢印参照）、用紙Ｐ１を搬送方向と逆方向に戻す（図７の用紙Ｐ１の矢印参照）。   FIG. 7 is a perspective view illustrating an example of the alignment operation in the transport direction of the paper P1 by the tapping roller 12 in the paper processing apparatus 1 of the present embodiment. When the paper P1 conveyed to the staple tray 11 collides with the pop-out preventing members 9a and 9b and is stacked on the staple tray 11, as shown in FIG. 7, the stacked paper P1 is struck and the rollers 12 are struck (see FIG. 7). The sheet P1 is returned to the direction opposite to the transport direction (see the arrow of the sheet P1 in FIG. 7).

図８は、本実施形態の用紙処理装置１において、用紙Ｐ１が搬送方向で揃えられた状態の一例を示す斜視図である。用紙搬送方向の揃え動作が行われると、図８に示すように、用紙Ｐ１の後端が後端フェンス１３ａ、ｂへ突き立てられ、用紙の搬送方向で揃えられる。そして、叩きコロ１２が元の位置に戻ると（図８の叩きコロ１２の矢印参照）、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、飛出防止ポジションから、飛び出し防止部材９ａ、ｂがそれぞれ移動孔１１ａ、ｂの用紙搬送方向後方に位置するとともに押さえ部材１０ａ、ｂがステイプルトレイ１１の用紙スタック面側に位置する押さえ準備ポジションへの移動を開始する（図８の押さえ部材１０ａの矢印参照）。   FIG. 8 is a perspective view illustrating an example of a state in which the sheets P1 are aligned in the transport direction in the sheet processing apparatus 1 of the present embodiment. When the alignment operation in the sheet conveyance direction is performed, as shown in FIG. 8, the rear end of the sheet P1 is projected to the rear end fences 13a and 13b, and is aligned in the sheet conveyance direction. When the hitting roller 12 returns to the original position (see the arrow of the hitting roller 12 in FIG. 8), the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are moved from the pop-out preventing position. The pop-out prevention members 9a and 9b are located behind the movement holes 11a and b in the sheet conveying direction, and the pressing members 10a and 10b start to move to a pressing preparation position positioned on the sheet stack surface side of the staple tray 11 (FIG. 8 (see arrow of pressing member 10a).

具体的には、叩きコロ１２が元の位置に戻ると、図示せぬ制御装置によりステッピングモータ２２が駆動される。これにより、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、用紙搬送方向と逆方向に移動し、飛出防止ポジションから押さえ準備ポジションに移動する。   Specifically, when the hitting roller 12 returns to the original position, the stepping motor 22 is driven by a control device (not shown). As a result, the pop-out prevention member 9a and the pressing member 10a, and the pop-out prevention member 9b and the pressing member 10b move in the direction opposite to the paper transport direction, and move from the pop-out prevention position to the press preparation position.

なお、押さえ準備ポジションは、用紙サイズや用紙に施された折り処理に応じて異ならせるようにしてもよい。このようにすれば、新たにステイプルトレイにスタックされる用紙のスタック不良をより低減することができる。   Note that the presser preparation position may be varied depending on the paper size and the folding process applied to the paper. In this way, it is possible to further reduce the stacking failure of sheets newly stacked on the staple tray.

図９は、本実施形態の用紙処理装置１において、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂが押さえ準備ポジションに位置する状態の一例を示す斜視図である。飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、図９に示すように、押さえ準備ポジションに移動すると、続いて、押さえ準備ポジションから、押さえ部材１０ａ、ｂが後端フェンス１３ａ、ｂへ突き立てられている用紙Ｐ１をステイプルトレイ１１に押さえつける押さえポジションへの移動を開始する（図９の押さえ部材１０ａの矢印参照）。   FIG. 9 is a perspective view illustrating an example of a state in which the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are located at the press preparation position in the paper processing apparatus 1 according to the present embodiment. As shown in FIG. 9, when the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b move to the pressing preparation position, the pressing members 10a and 10b are moved from the pressing preparation position to the rear end. The movement to the pressing position that presses the paper P1 protruding to the fences 13a and 13b against the staple tray 11 is started (see the arrow of the pressing member 10a in FIG. 9).

具体的には、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂが押さえ準備ポジションに移動すると、図示せぬ制御装置によりソレノイド２３が駆動される。これにより、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、押さえ準備ポジションから、用紙押さえ方向に移動し、飛び出し防止部材９ａ、ｂがそれぞれ移動孔１１ａ、ｂの用紙搬送方向後方に位置するとともに押さえ部材１０ａ、ｂが用紙Ｐ１をステイプルトレイ１１に押さえつける押さえポジションに移動する。   Specifically, when the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b move to the pressing preparation position, the solenoid 23 is driven by a control device (not shown). As a result, the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are moved from the press preparation position in the paper pressing direction, and the pop-out preventing members 9a and 9b are moved to the paper in the moving holes 11a and b, respectively. The pressing members 10a and 10b are located at the rear in the transport direction and move to a pressing position that presses the paper P1 against the staple tray 11.

なお、図示は省略するが、ジョガーフェンス１４ａ、ｂによる用紙幅方向での揃え動作は、用紙Ｐ１が後端フェンス１３ａ、ｂへ突き立てられた後、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂが押さえ準備ポジションから押さえポジションへの移動を開始する前に行うものとする。但しこれに限定されるものではない。   Although not shown in the drawings, the jogger fences 14a and 14b perform the alignment operation in the paper width direction after the paper P1 is pushed to the rear end fences 13a and 13b, and then the pop-out prevention member 9a and the pressing member 10a. It is assumed that the prevention member 9b and the pressing member 10b are performed before the movement from the pressing preparation position to the pressing position is started. However, it is not limited to this.

図１０は、本実施形態の用紙処理装置１において、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂが押さえポジションに位置する状態の一例を示す斜視図である。図１０に示すように、押さえ部材１０ａ、ｂが後端フェンス１３ａ、ｂへ突き立てられている用紙Ｐ１をステイプルトレイ１１に押さえつけると、その後、２枚目の山折り用紙Ｐ２がステイプルトレイ１１に搬送されてくるので（図１０の用紙Ｐ２の矢印参照）、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、押さえポジションからホームポジションへの移動を開始する（図１０の飛び出し防止部材９ａの矢印参照）。   FIG. 10 is a perspective view illustrating an example of a state in which the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are located at the pressing position in the paper processing apparatus 1 according to the present embodiment. As shown in FIG. 10, when the pressing members 10 a and b press the paper P <b> 1 protruding to the rear end fences 13 a and 13 b against the staple tray 11, the second mountain folded paper P <b> 2 is then placed on the staple tray 11. Since it is conveyed (see the arrow of the paper P2 in FIG. 10), the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b start to move from the pressing position to the home position (FIG. 10). (See the arrow of the pop-out prevention member 9a).

具体的には、図示せぬ制御装置によりソレノイド２３及びステッピングモータ２２が駆動され、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、用紙押さえ方向及び用紙搬送方向に移動し、押さえポジションからホームポジションへ移動する。   Specifically, the solenoid 23 and the stepping motor 22 are driven by a control device (not shown), and the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b move in the sheet pressing direction and the sheet conveying direction. Then, move from the holding position to the home position.

図１１は、本実施形態の用紙処理装置１において、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂがホームポジションに位置する状態の一例を示す斜視図である。飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、２枚目の山折り用紙Ｐ２がステイプルトレイ１１に搬送されてくるのをホームポジションで待機する。そして、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、図１１に示すように、２枚目の山折り用紙Ｐ２がステイプルトレイ１１に搬送されてくると（図１１の用紙Ｐ２の矢印参照）、ホームポジションから飛出防止ポジションへの移動を開始する（図１１の飛び出し防止部材９ａの矢印参照）。   FIG. 11 is a perspective view showing an example of a state in which the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are located at the home position in the paper processing apparatus 1 according to the present embodiment. The pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b wait at the home position for the second mountain folded paper P2 to be conveyed to the staple tray 11. As shown in FIG. 11, the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are transported to the staple tray 11 as shown in FIG. The movement from the home position to the pop-out prevention position is started (see the arrow of the pop-out prevention member 9a in FIG. 11).

図１２は、本実施形態の用紙処理装置１において、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂが飛出防止ポジションに移動した状態の一例を示す斜視図である。ステイプルトレイ１１に搬送された用紙Ｐ２は、飛び出し防止部材９ａ、ｂにぶつかり、図１２に示すように、ステイプルトレイ１１にスタックされる。   FIG. 12 is a perspective view showing an example of a state in which the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b are moved to the pop-out preventing position in the paper processing apparatus 1 according to the present embodiment. The sheet P2 conveyed to the staple tray 11 collides with the pop-out preventing members 9a and 9b and is stacked on the staple tray 11 as shown in FIG.

以降、用紙Ｐ２に対しても、用紙搬送方向での揃え動作、用紙幅方向での揃え動作、用紙押さえ動作が行われる。そして、用紙Ｐ２に対する用紙押さえ動作が行われると、ステイプルユニット１５は、押さえ部材１０ａ、ｂにより用紙Ｐ１及びＰ２がステイプルトレイ１１に押さえつけられた状態でステイプルを行う。ステイプル実行後、飛び出し防止部材９ａ及び押さえ部材１０ａ、並びに飛び出し防止部材９ｂ及び押さえ部材１０ｂは、押さえポジションからホームポジションへ移動する。そして、ステイプルされた用紙Ｐ１及びＰ２の束は、ステイプル処理部４に備えられている図示せぬ放出機構により排紙トレイ５に放出される。   Thereafter, the alignment operation in the sheet conveyance direction, the alignment operation in the sheet width direction, and the sheet pressing operation are also performed on the sheet P2. When the sheet pressing operation is performed on the sheet P2, the staple unit 15 performs the stapling in a state where the sheets P1 and P2 are pressed against the staple tray 11 by the pressing members 10a and 10b. After the stapling is performed, the pop-out preventing member 9a and the pressing member 10a, and the pop-out preventing member 9b and the pressing member 10b move from the pressing position to the home position. The bundle of stapled sheets P1 and P2 is discharged to the paper discharge tray 5 by a discharge mechanism (not shown) provided in the staple processing unit 4.

以上のように、本実施形態によれば、ステイプルトレイに用紙がスタックされる毎に押さえ部材がステイプルトレイにスタックされている用紙をステイプルトレイに押さえつける。このため、折り処理が施された用紙がステイプルトレイにスタックされていてもステイプルトレイにスタック中の用紙の膨らみを抑えることができ、新たにステイプルトレイにスタックされる用紙のスタック不良を低減することができる。   As described above, according to the present embodiment, each time a sheet is stacked on the staple tray, the pressing member presses the sheet stacked on the staple tray against the staple tray. For this reason, even if the folded paper is stacked on the staple tray, the expansion of the paper in the stack on the staple tray can be suppressed, and the stacking failure of the paper newly stacked on the staple tray can be reduced. Can do.

また、本実施形態によれば、ステイプルトレイに用紙が搬送される毎に飛び出し防止部材が搬送された用紙のステイプルトレイからの飛び出しを防止する。このため、新たにステイプルトレイにスタックされる用紙のスタック不良を低減することができる。   Further, according to the present embodiment, the pop-out prevention member prevents the paper transported from the staple tray from being ejected each time the paper is transported to the staple tray. For this reason, it is possible to reduce the stacking failure of the paper newly stacked on the staple tray.

また、本実施形態によれば、押さえ部材が飛び出し防止部材により支持されており、１の機構で用紙の押さえつけ及び飛び出し防止を実現できる。   In addition, according to the present embodiment, the pressing member is supported by the pop-out preventing member, and it is possible to realize sheet pressing and pop-out prevention with one mechanism.
