Description

本発明は、複写機、プリンタ、印刷機などの画像形成装置に併設する用紙後処理装置、及びこの用紙後処理装置を備えている画像形成システムに関するものである。   The present invention relates to a sheet post-processing apparatus provided in an image forming apparatus such as a copying machine, a printer, and a printing machine, and an image forming system including the sheet post-processing apparatus.

画像形成装置本体の下流側へ配置され、これから出力される記録紙などに綴じなどの後処理を施す用紙後処理装置は広く知られている。昨今、その機能は多機能化され、従来の端面綴じに加えて中綴じ処理も可能としたものが広く提案されている。かかる用紙後処理装置の普及に伴い、中綴じ時の折り部の膨らみの縮小、小口裁断等の製本品質向上への要求が高まってきているのが現状である。
中綴じ時の品質向上の1つとして、従来は用紙を搬送しつつ、用紙束の折り部全体をローラのニップで加圧する方式に代わり、用紙束を所定位置に停止させ、用紙搬送方向に直交する方向に移動可能な折りローラを移動させ、折り目部を強化する方法が提案されている(例えば、特許文献1乃至3参照)。
この方式のメリットとしては、折り部に対し局部的に押圧できるため比較的加圧力を弱くでき、必要な動力が少なく省エネルギであること、さらに加圧力が低いので、シワ、汚れ等の外観品質が向上すること等がある。

2. Description of the Related Art A sheet post-processing apparatus that is disposed on the downstream side of an image forming apparatus main body and performs post-processing such as binding on recording paper to be output from now on is widely known. In recent years, the functions have been multi-functionalized, and it has been widely proposed to be able to perform saddle stitching processing in addition to the conventional end face binding. With the widespread use of such a sheet post-processing apparatus, there is an increasing demand for bookbinding quality improvement such as reduction of the bulge of the folding portion at the time of saddle stitching and small edge cutting.
As one of the quality improvements at the time of saddle stitching, instead of conventionally pressing the entire folded portion of the sheet bundle with the nip of the roller while conveying the sheet, the sheet bundle is stopped at a predetermined position and orthogonal to the sheet conveying direction. A method has been proposed in which a folding roller that is movable in the direction of movement is moved to reinforce the crease (see, for example, Patent Documents 1 to 3).
The advantages of this method are that it can be pressed locally against the folded part, so that the applied pressure can be relatively weak, less power is required and energy is saved, and the applied pressure is low, so the appearance quality of wrinkles, dirt, etc. May improve.

図2乃至図8を参照して、本実施形態の増し折り動作について説明する。
折りローラ4及び折りプレート3により中折りされた用紙は、折り部を先頭にしてカッターユニットCに進入する。図2に示すカッターユニットCの上流に設けられたセンサSN1が紙先端部を検知すると、図3に示すように増し折りローラユニット移動モータ22が、用紙サイズ情報及び切断の長さ情報に基づき所定量回転し、束搬送駆動モータ24により束搬送ローラ9を回転させる。
次に、用紙束検知センサ16の用紙先端検知情報に基づき、用紙束を束搬送ローラ9にて所定量搬送したところで停止する。この停止位置は、図5に示すように、用紙束の折り部が折りローラ4のニップを出て、かつ用紙束後端の小口が所定量の切断長さを確保した位置である。
次に、増し折りローラ7による所定の増し折り動作が開始され、続けてトリマが動作することにより小口の断裁が行われる。トリミング動作が終了後、増し折り動作を行いつつ、図6に示すように増し折りローラユニット5は排紙ローラ12方向への移動を行う。
増し折り動作が終了すると、停止していた束搬送駆動モータ24が回転し、用紙束を排紙ローラ12方向へ搬送するとともに、排紙ローラ12も駆動され用紙束の排出が行われる(図7)。
With reference to FIG. 2 thru | or FIG. 8, the additional folding operation | movement of this embodiment is demonstrated.
The sheet folded in half by the folding roller 4 and the folding plate 3 enters the cutter unit C with the folding portion at the top. When the sensor SN1 provided upstream of the cutter unit C shown in FIG. 2 detects the leading edge of the paper, the additional folding roller unit moving motor 22 is operated based on the paper size information and the cutting length information as shown in FIG. The bundle transport roller 9 is rotated by the bundle transport driving motor 24 after a fixed amount of rotation.
Next, based on the sheet leading edge detection information of the sheet bundle detection sensor 16, the sheet bundle is stopped when a predetermined amount is conveyed by the bundle conveying roller 9. As shown in FIG. 5, the stop position is a position where the folded portion of the sheet bundle exits the nip of the folding roller 4 and the fore edge at the rear end of the sheet bundle secures a predetermined amount of cutting length.
Next, a predetermined additional folding operation by the additional folding roller 7 is started, and then the trimmer is operated to cut the fore edge. After completion of the trimming operation, the additional folding roller unit 5 moves in the direction of the paper discharge roller 12 as shown in FIG.
When the additional folding operation is completed, the stopped bundle conveyance drive motor 24 rotates to convey the sheet bundle toward the sheet discharge roller 12, and the sheet discharge roller 12 is also driven to discharge the sheet bundle (FIG. 7). ).

図8のフローチャートを用いてさらに説明すると、先ず、センサSN1がオンかどうか判断する(S1)。オンであるならば、増し折りローラユニット移動モータ22を所定量回転する(S2)。次に、束搬送駆動モータ24を回転させる(S3)。
用紙束検知センサ16がオンかどうかを判断し(S4)、オンならば、所定量搬送したら束搬送駆動モータ24の回転を停止する(S5)。次いで増し折り動作を開始し(S6)、トリミング動作を行う(S7)。次に、増し折りローラユニット移動モータ22を所定量回転する(S8)。
続いて、増し折り動作終了かどうかを判断する(S9)。終了でないならば、さらに増し折り動作を行う(S10)。
ステップS9において増し折り動作終了ならば、束搬送駆動モータ24を回転し(S11)、排紙ローラ12の駆動を開始する(S12)。次いで、センサSN2がオフかどうか判断する(S13)。オフならば、所定時間後排紙ローラ12の駆動を停止する(S14)。
以上により、切断後の用紙を増し折り動作を行いつつ、排紙ローラ12への搬送を行い、切断部から用紙束をすばやく退避させることで、従来生産性に対して不利とされていた搬送方向に直交に増し折りローラ7を移動させる増し折りローラユニット5においても次の用紙束の受け入れに対する待ち時間を最小とし、生産性を向上させることができる。また、前記増し折り方式によれば省エネルギで、シワ、汚れ等のない高品質な用紙後処理装置を提供することができる。
This will be further described with reference to the flowchart of FIG. 8. First, it is determined whether or not the sensor SN1 is on (S1). If it is ON, the additional folding roller unit moving motor 22 is rotated by a predetermined amount (S2). Next, the bundle conveyance drive motor 24 is rotated (S3).
It is determined whether or not the sheet bundle detection sensor 16 is on (S4). If the sheet bundle detection sensor 16 is on, rotation of the bundle conveyance drive motor 24 is stopped after a predetermined amount of conveyance (S5). Next, an additional folding operation is started (S6), and a trimming operation is performed (S7). Next, the additional folding roller unit moving motor 22 is rotated by a predetermined amount (S8).
Subsequently, it is determined whether or not the additional folding operation is completed (S9). If not finished, a further folding operation is performed (S10).
If the additional folding operation is completed in step S9, the bundle conveying drive motor 24 is rotated (S11), and the drive of the paper discharge roller 12 is started (S12). Next, it is determined whether the sensor SN2 is off (S13). If it is off, the drive of the paper discharge roller 12 is stopped after a predetermined time (S14).
As described above, the direction of conveyance, which has been disadvantageous for the conventional productivity, is achieved by performing conveyance to the paper discharge roller 12 while performing an additional folding operation of the cut sheet, and quickly retracting the sheet bundle from the cutting unit. Even in the additional folding roller unit 5 that moves the additional folding roller 7 orthogonally to the vertical direction, the waiting time for receiving the next sheet bundle can be minimized and the productivity can be improved. Further, according to the additional folding method, it is possible to provide a high-quality sheet post-processing apparatus that is energy-saving and free from wrinkles and dirt.
