　例えば、一般的な新聞用オフセット輪転印刷機は、複数の給紙装置と、複数の印刷ユニットと、ターンバー装置と、折機とから構成されており、各給紙装置から印刷ユニットにウェブが供給されると、各ウェブに対して印刷が施され、ターンバー装置で多数のウェブの走行ルートが変更されてから所定の順番に重ね合わされた後、折機にて、ウェブが縦折りされてから所定の長さで横裁断され、横折されることで折帖が形成され、排紙される。 For example, a general web offset press for newspapers is composed of a plurality of paper feeding devices, a plurality of printing units, a turn bar device, and a folding machine, and a web is supplied from each paper feeding device to the printing unit. Then, printing is performed on each web, and after a plurality of web traveling routes are changed by the turn bar device, the webs are overlapped in a predetermined order, and then the web is vertically folded by a folding machine. The paper is cut by the length of, and a fold is formed by being horizontally folded, and is discharged.
　このような新聞用オフセット輪転印刷機における折機には、ロータリ（ブレード）フォルダ式とジョウフォルダ式の２種類がある。ロータリフォルダ式の折機は、縦折りを行う三角板の下方に鋸胴と折胴が対向して設けられていると共に、折胴の下方に一対の折込ローラが設けられ、この折込ローラの下方に折帖を排紙する羽根車が設けられて構成されている。この鋸胴は、外周部に鋸刃が装着される一方、折胴は、外周部にこの鋸刃を受け止める鋸刃受が装着されている。また、折胴は、外周部に針装置と折ブレードが周方向に所定の間隔で設けられている。 There are two types of folding machines in such newspaper rotary printing presses: rotary (blade) folder type and jaw folder type. The rotary folder type folding machine is provided with a saw cylinder and a folding cylinder facing each other below a triangular plate for vertical folding, and a pair of folding rollers provided below the folding cylinder, below the folding rollers. An impeller for discharging the signature is provided. The saw cylinder is provided with a saw blade on the outer peripheral portion, while the folding cylinder is provided with a saw blade receiver for receiving the saw blade on the outer peripheral portion. Further, the folding cylinder is provided with a needle device and a folding blade at an outer peripheral portion at a predetermined interval in the circumferential direction.
　従って、所定の順番に重ね合わせられた複数のウェブは、三角板により縦折りが施された後、各種ローラにより折胴に送られると、まず、所定の位置で針装置によりその先端部が保持され、この状態で折胴が所定角度回転する。次に、鋸胴にて、鋸刃と鋸刃受が一致し、この鋸刃によりウェブがシート状に裁断されると共に、針装置によるウェブの保持が解除される。続いて、折胴の折ブレードが回動して先端部が折胴の周面から突出し、シートを折胴の周面から引き剥がす。一方、一対の折込ローラが折胴の周面から引き剥がされたシートを挟持することで折帖が形成され、この折帖は羽根車により順次受取られて排紙される。 Therefore, when a plurality of webs stacked in a predetermined order are vertically folded by a triangular plate and then sent to the folding cylinder by various rollers, first, the tip portions are held by the needle device at a predetermined position. In this state, the folding cylinder rotates by a predetermined angle. Next, the saw blade and the saw blade support coincide with each other in the saw cylinder, and the web is cut into a sheet shape by the saw blade, and the holding of the web by the needle device is released. Subsequently, the folding blade of the folding cylinder is rotated so that the leading end projects from the circumferential surface of the folding cylinder, and the sheet is peeled off from the circumferential surface of the folding cylinder. On the other hand, a pair of folding rollers sandwich the sheet peeled off from the peripheral surface of the folding cylinder to form a signature, and the signature is sequentially received by the impeller and discharged.
　一方、ジョウフォルダ式の折機は、縦折りを行う三角板の下方に鋸胴と折胴と咥胴がそれぞれ対向して設けられていると共に、咥胴の下方に折帖を排紙する羽根車が設けられて構成されている。この鋸胴は、外周部に鋸刃が装着される一方、折胴は、外周部にこの鋸刃を受け止める鋸刃受が装着されている。また、折胴は、外周部に針装置と折ブレードが周方向に所定の間隔で設けられている。さらに、咥胴は、外周部に咥え装置が周方向に所定の間隔で設けられている。 On the other hand, in the jaw folder type folding machine, a saw cylinder, a folding cylinder, and a saddle cylinder are respectively provided below a triangular plate that performs vertical folding, and an impeller that discharges signatures below the saddle cylinder.

Further, the folding cylinder is provided with a needle device and a folding blade at an outer peripheral portion at a predetermined interval in the circumferential direction. Further, the collar body is provided with a gripping device at a predetermined interval in the circumferential direction on the outer peripheral portion.
　従って、所定の順番に重ね合わせられた複数のウェブは、三角板により縦折りが施された後、各種ローラにより折胴に送られると、まず、所定の位置で針装置によりその先端部が保持され、この状態で折胴が所定角度回転する。次に、鋸胴にて、鋸刃と鋸刃受が一致してこの鋸刃によりウェブがシート状に裁断されると共に、針装置によるウェブの保持が解除される。続いて、折胴の折ブレードが前進して先端部が折胴の周面から突出し、ウェブを折胴の周面から引き剥がす。一方、咥胴の咥え装置が折胴の周面から引き剥がされたシートを挟持することで折帖が形成され、この折帖は羽根車により順次受取られて排紙される。 Therefore, when a plurality of webs stacked in a predetermined order are vertically folded by a triangular plate and then sent to the folding cylinder by various rollers, first, the tip portions are held by the needle device at a predetermined position. In this state, the folding cylinder rotates by a predetermined angle. Next, in the saw cylinder, the saw blade and the saw blade support coincide with each other, and the web is cut into a sheet by the saw blade, and the holding of the web by the needle device is released. Subsequently, the folding blade of the folding cylinder moves forward, the tip projects from the circumferential surface of the folding cylinder, and the web is peeled off from the circumferential surface of the folding cylinder. On the other hand, a folding device is formed by holding the sheet peeled off from the peripheral surface of the folding cylinder by the clamping device of the folding cylinder, and the folding is sequentially received by the impeller and discharged.

　折胴１０１１は、円柱状に形成された回転可能な胴部１０１１ａの周面に保持部１０１１ｂが設けられている。保持部１０１１ｂは、胴部１０１１ａの回転軸心を挟んで１８０度対向した位置の２箇所で、胴部１０１１ａの軸の延在方向に沿って複数配置されている。この保持部１０１１ｂは、図には明示しないが、カム機構により折胴１０１１の回転に連動して作動するものであり、所定の位置で胴部１０１１ａの周面から外側に突出させた針によりシート群Ｓ’の端部を刺して保持することができる一方、所定の位置で針を胴部１０１１ａの周面の内側に待避させてシート群Ｓ’の端部の保持を解除することができる。 The folding cylinder 1011 is provided with a holding portion 1011b on the peripheral surface of a rotatable barrel portion 1011a formed in a columnar shape. A plurality of holding parts 1011b are arranged along the extending direction of the axis of the body part 1011a at two positions 180 degrees opposite to each other with the rotation axis of the body part 1011a interposed therebetween. Although not clearly shown in the drawing, the holding portion 1011b is operated in conjunction with the rotation of the folding cylinder 1011 by a cam mechanism, and the sheet is formed by a needle protruding outward from the peripheral surface of the trunk portion 1011a at a predetermined position. While the end portion of the group S ′ can be stabbed and held, the holding of the end portion of the sheet group S ′ can be released by retracting the needle inside the peripheral surface of the body portion 1011a at a predetermined position.
　また、折胴１０１１は、胴部１０１１ａの周面に折ブレード１０１１ｃが設けられている。保持部１０１１ｂは、保持部１０１１ｂとほぼ９０度位相がずれ、胴部１０１１ａの回転軸心を挟んで１８０度対向した位置の２箇所で、胴部１０１１ａの軸の延在方向に亘って配置されている。この折ブレード１０１１ｃは、図には明示しないが、カム機構により折胴１０１１の回転に連動して作動するものであり、所定の位置で胴部１０１１ａの周面の外側に突出することで、シート群Ｓ’の一部（中央部）を胴部１０１１ａの周面から外側に押し出して引き剥がす一方、所定の位置で胴部１０１１ａの周面の内側に待避してシート群Ｓ’から離隔する。 Further, the folding cylinder 1011 is provided with a folding blade 1011c on the peripheral surface of the trunk portion 1011a. The holding unit 1011b is arranged at two positions 180 degrees out of phase with the holding unit 1011b and opposed to each other by 180 degrees across the rotation axis of the barrel 1011a, and extends in the extending direction of the axis of the barrel 1011a. ing. Although not shown in the drawing, the folding blade 1011c is operated in conjunction with the rotation of the folding cylinder 1011 by a cam mechanism, and protrudes to the outside of the peripheral surface of the trunk 1011a at a predetermined position. A part (central part) of the group S ′ is pushed outward from the peripheral surface of the body part 1011a to be peeled off, and is separated from the sheet group S ′ by being retracted inside the peripheral surface of the body part 1011a at a predetermined position.
　咥胴１０１２は、折胴１０１１と同じ直径の円柱状に形成された胴部１０１２ａの周面に咥機構１０１２ｂが設けられている。咥機構１０１２ｂは、胴部１０１２ａの回転軸心を挟んで１８０度対向した位置の２箇所で、胴部１０１２ａの軸の延在方向に沿って複数配置されている。 The saddle drum 1012 is provided with a saddle mechanism 1012b on the peripheral surface of a barrel portion 1012a formed in a cylindrical shape having the same diameter as the folding drum 1011. A plurality of scissors mechanisms 1012b are arranged along the extending direction of the shaft of the trunk portion 1012a at two positions facing each other by 180 degrees across the rotation axis of the trunk portion 1012a.
　これら折胴１０１１と咥胴１０１２とは、互いに逆方向に同期して回転可能に構成されており、かつ回転に際して移動する折ブレード１０１１ｃと咥機構１０１２ｂとが互いに対向するように回転位相が一致されている。そして、折ブレード１０１１ｃと咥機構１０１２ｂとが互いに対向して合致したとき、折胴１０１１の保持部１０１１ｂで保持されていたシート群Ｓ’が、折ブレード１０１１ｃにより押し出されつつ咥機構１０１２ｂにより咥えられる。すなわち、折ブレード１０１１ｃにより押し出されたシート群Ｓ’の一部（中央部）が咥機構１０１２ｂにより咥えられて折り目となって横折りされる。また、本実施の形態における第一折畳部１０１は、折胴１０１１の胴部１０１１ａの周面の２箇所に折ブレード１０１１ｃが設けられ、咥胴１０１２の胴部１０１２ａの周面の２箇所に咥機構１０１２ｂが設けられていることから、折胴１０１１及び咥胴１０１２の半周につき１つのシート群Ｓ’を横折りする。なお、第一折畳部１０１は、折胴１０１１の胴部１０１１ａの周面の１箇所に折ブレード１０１１ｃが設けられ、咥胴１０１２の胴部１０１２ａの周面の１箇所に咥機構１０１２ｂが設けられている構成であれば、折胴１０１１及び咥胴１０１２の１周につき１つのシート群Ｓ’を横折りすることになる。 The folding cylinder 1011 and the saddle cylinder 1012 are configured to be rotatable in synchronization with each other in the opposite directions, and the rotational phases are matched so that the folding blade 1011c and the saddle mechanism 1012b that move during the rotation face each other. ing. When the folding blade 1011c and the scissor mechanism 1012b face each other and match, the sheet group S ′ held by the holding unit 1011b of the folding cylinder 1011 is pushed by the scissor mechanism 1012b while being pushed out by the folding blade 1011c. It is done. That is, a part (center portion) of the sheet group S ′ pushed out by the folding blade 1011 c is held by the folding mechanism 1012 b and is folded horizontally as a fold. Further, the first folding unit 101 in the present embodiment is provided with folding blades 1011c at two locations on the circumferential surface of the trunk portion 1011a of the folding drum 1011 and at two locations on the circumferential surface of the trunk portion 1012a of the rod barrel 1012. Since the scissors mechanism 1012b is provided, one sheet group S ′ is folded horizontally per half circumference of the folding cylinder 1011 and the saddle cylinder 1012. The first folding unit 101 is provided with a folding blade 1011c at one location on the circumferential surface of the barrel portion 1011a of the folding drum 1011 and a saddle mechanism 1012b at one location on the circumferential surface of the barrel portion 1012a of the saddle barrel 1012. In the case of the configuration, one sheet group S ′ is folded horizontally per one turn of the folding cylinder 1011 and the rod cylinder 1012.
　第二折畳部１０２は、第一折畳部１０１により横折りされたシート群Ｓ’をシート群Ｓ’の送り方向Ｒに沿う方向で縦折りして折帖を形成するものであり、チョッパ装置として構成されている。 The second folding unit 102 is configured to vertically fold the sheet group S ′ horizontally folded by the first folding unit 101 in a direction along the feeding direction R of the sheet group S ′ to form a fold. It is configured as a device.
　チョッパ装置は、第一折畳部１０１の咥胴１０１２に隣接して設けられている。このチョッパ装置は、チョッパテーブル１０２１が水平に配設されている。チョッパテーブル１０２１の位置には、咥胴１０１２が開放した横折りのシート群Ｓ’を上下方向から挟むように設けられた１対のコンベア１０２２が配置されている。各コンベア１０２２は、複数のプーリ１０２２ａと、各プーリ１０２２ａに掛け渡された無端状のベルト１０２２ｂとを有し、プーリ１０２２ａの回転によりベルト１０２２ｂが循環するように構成されている。各コンベア１０２２は、ベルト１０２２ｂが互いに逆方向に同期して回転可能に構成され、チョッパテーブル１０２１の上面位置にて各ベルト１０２２ｂの間でシート群Ｓ’を挟みつつ搬送する。 The chopper device is provided adjacent to the rod body 1012 of the first folding unit 101. In this chopper device, a chopper table 1021 is disposed horizontally. At the position of the chopper table 1021, a pair of conveyors 1022 provided so as to sandwich the horizontally folded sheet group S ′ with the rod cylinder 1012 open from above and below is arranged. Each conveyor 1022 has a plurality of pulleys 1022a and an endless belt 1022b stretched over each pulley 1022a, and is configured such that the belt 1022b circulates as the pulley 1022a rotates. Each conveyor 1022 is configured such that the belts 1022b can rotate in synchronization with each other in opposite directions, and conveys the sheet group S 'between the belts 1022b at the upper surface position of the chopper table 1021.
　チョッパテーブル１０２１は、その所定の位置にシート群Ｓ’の送り方向Ｒに沿ってスリット１０２１ａが形成されており。さらにチョッパテーブル１０２１には、スリット１０２１ａよりシート群Ｓ’の送り方向Ｒの下流側にストッパ１０２１ｂが設けられている。このストッパ１０２１ｂは、各コンベア１０２２により搬送されるシート群Ｓ’の先端部が当接することで、シート群Ｓ’の折り位置を規定するものである。 The chopper table 1021 has slits 1021a formed at predetermined positions along the feeding direction R of the sheet group S '. Further, the chopper table 1021 is provided with a stopper 1021b on the downstream side in the feeding direction R of the sheet group S 'from the slit 1021a. The stopper 1021b defines the folding position of the sheet group S 'when the leading end of the sheet group S' conveyed by each conveyor 1022 comes into contact.
　また、スリット１０２１ａの上方には、チョッパブレード１０２３が配置されている。チョッパブレード１０２３は、スリット１０２１ａに挿通可能な板状に形成され、ストッパ１０２１ｂに当接したシート群Ｓ’の幅方向の中央部に接触しつつシート群Ｓ’をスリット１０２１ａ内に押し込むように図示しない昇降手段により上下方向に移動可能に構成されている。スリット１０２１ａを通過して下降したシート群Ｓ’は、中央部に縦折りの折り目が形成されて折帖となる。 Further, a chopper blade 1023 is disposed above the slit 1021a. The chopper blade 1023 is formed in a plate shape that can be inserted into the slit 1021a, and pushes the sheet group S ′ into the slit 1021a while being in contact with the central portion in the width direction of the sheet group S ′ that is in contact with the stopper 1021b. It is configured to be movable in the vertical direction by the lifting means that does not. The sheet group S ′ descending after passing through the slit 1021a is formed with a longitudinal fold at the center to form a fold.
　なお、上述した各コンベア１０２２のベルト１０２２ｂは、シート群Ｓ’の幅方向で所定隙間をもって複数並設されており、チョッパテーブル１０２１のスリット１０２１ａに対応する位置に隙間を有している。 Note that a plurality of the belts 1022b of each conveyor 1022 described above are arranged side by side with a predetermined gap in the width direction of the sheet group S ', and have gaps at positions corresponding to the slits 1021a of the chopper table 1021.
　また、チョッパテーブル１０２１の下方には、スリット１０２１ａに対向して、一対の折込ローラ１０２４が回転可能に設けられている。折込ローラ１０２４は、スリット１０２１ａを通過して下降する折帖をニップ圧により挟み込んで折り曲げる。また、折込ローラ１０２４の下方には、折帖を受け取って排紙装置６に送る排紙コンベア１０２５が設けられている。 In addition, a pair of folding rollers 1024 is rotatably provided below the chopper table 1021 so as to face the slit 1021a. The folding roller 1024 sandwiches and folds the signature that descends through the slit 1021a by the nip pressure. Further, below the folding roller 1024, a paper discharge conveyor 1025 that receives a signature and sends it to the paper discharge device 6 is provided.
　したがって、折り装置（折機）５では、連続して異なる画像が印刷されたウェブＷを、断裁装置７により画像ごとの所定長さのシートＳに裁断し、次に重ね装置８によりシートＳの端部を位置決めしつつ予め設定された所定枚数を重ねたシート群Ｓ’とし、次に搬送装置９によりシート群Ｓ’を搬送し、次に搬送されたシート群Ｓ’を折畳装置１０により一括して受け取ってから折り畳んで折帖を形成する。 Therefore, in the folding device (folder) 5, the web W on which different images are continuously printed is cut into a sheet S having a predetermined length for each image by the cutting device 7, and then the sheet S is formed by the overlapping device 8. The sheet group S ′ is formed by stacking a predetermined number of sheets set in advance while positioning the end, and then the sheet group S ′ is conveyed by the conveying device 9, and the conveyed sheet group S ′ is then conveyed by the folding device 10. Fold it together and fold it to form a signature.
　ところで、載置台８１に重ねられるシートＳの所定枚数は、ウェブＷに印刷される画像数に応じて予め設定されている。この所定枚数は、予め印刷機１に設定された画像数や、断裁装置７における断裁数（鋸胴７１１及び受胴７１２の回転数）や、断裁装置７と重ね装置８との間に設けたセンサ（図示せず）などから知ることができる。 Incidentally, the predetermined number of sheets S stacked on the mounting table 81 is set in advance according to the number of images printed on the web W. The predetermined number is provided in advance between the number of images set in the printing machine 1, the number of cuts in the cutting apparatus 7 (the number of rotations of the saw cylinder 711 and the receiving cylinder 712), and between the cutting apparatus 7 and the stacking apparatus 8. It can be known from a sensor (not shown).
　また、載置台８１に重ねられてシート群Ｓ’となるシートＳの枚数は、印刷物のページ数に伴う。したがって、同じ印刷物を連続して印刷する場合、載置台８１に重ねられるシートＳの枚数は印刷物ごとに同じであるが、別の印刷物を印刷するときには、そのページ数に伴って載置台８１に重ねられるシートＳの枚数は変わる。 Further, the number of sheets S stacked on the mounting table 81 to become the sheet group S ′ depends on the number of pages of the printed material. Therefore, when printing the same printed material continuously, the number of sheets S stacked on the mounting table 81 is the same for each printed material, but when printing another printed material, it is stacked on the mounting table 81 according to the number of pages. The number of sheets S to be changed varies.
　一方、載置台８１に重ねられたシート群Ｓ’を搬送装置９から受け取る第一折畳部１０１の折胴１０１１は、カム機構により折胴１０１１の回転に連動して作動することで、回転の所定の位置で胴部１０１１ａの周面から外側に突出させた針によりシート群Ｓ’の端部を刺して保持することで、シート群Ｓ’を受け取る。すなわち、上記回転の所定の位置は、シート群Ｓ’を搬送装置９から受け取る位置である。 On the other hand, the folding cylinder 1011 of the first folding unit 101 that receives the sheet group S ′ stacked on the mounting table 81 from the conveying device 9 is operated in conjunction with the rotation of the folding cylinder 1011 by the cam mechanism, so The sheet group S ′ is received by sticking and holding the end of the sheet group S ′ with a needle protruding outward from the peripheral surface of the body 1011 a at a predetermined position. That is, the predetermined position of the rotation is a position where the sheet group S ′ is received from the conveying device 9.
　このような構成においては、印刷物に応じて載置台８１に重ねられるシートＳの枚数が変わると、シートＳが所定枚数のシート群Ｓ’になるまでの時間が変わる。この場合、折胴１０１１では、シート群Ｓ’を搬送装置９から受け取る回転の所定の位置が決まっているため、載置台８１に重ねられるシートＳの枚数の変化に応じて回転速度、すなわち、折畳装置１０が搬送装置９からシート群Ｓ’を受け取るタイミングを変える必要がある。 In such a configuration, when the number of sheets S stacked on the mounting table 81 changes according to the printed matter, the time until the sheets S become a predetermined number of sheet groups S ′ changes. In this case, in the folding cylinder 1011, a predetermined rotation position for receiving the sheet group S ′ from the conveying device 9 is determined, so that the rotation speed, that is, the folding, is changed according to the change in the number of sheets S stacked on the mounting table 81. It is necessary to change the timing at which the tatami mat apparatus 10 receives the sheet group S ′ from the transport apparatus 9.
　そこで、本実施の形態では、制御部１００により、載置台８１に重ねられるシートＳの枚数の変化に応じて折胴１０１１の回転速度を制御している。制御部１００は、マイコンなどで構成されている。制御部１００には、印刷機１に設定された画像数や、断裁装置７における鋸胴７１１および受胴７１２の回転数や、断裁装置７と重ね装置８との間に設けたセンサ（図示せず）などから、載置台８１に重ねられるシートＳの所定枚数が入力される。また、制御部１００には、印刷装置４での印刷速度や、断裁装置７の断裁速度に相当する鋸胴７１１および受胴７１２の回転速度や、断裁装置７における断裁下流搬送部７３の搬送速度などから、載置台８１に送られるシートＳの送り速度が入力される。そして、制御部１００では、シートＳの送り速度とシートＳの所定枚数との比により定めた折胴１０１１の回転速度情報が予め記憶されており、この回転速度情報に基づいた回転速度となるように折胴１０１１を回転駆動するモータＭの回転数を制御する。なお、咥胴１０１２は、折胴１０１１と回転が同期するように、折胴１０１１のモータＭで駆動されている。したがって、折胴１０１１のモータＭの回転数を制御することで、折胴１０１１と同期する咥胴１０１２の回転速度も制御できる。 Therefore, in the present embodiment, the rotation speed of the folding cylinder 1011 is controlled by the control unit 100 in accordance with the change in the number of sheets S stacked on the mounting table 81. The control unit 100 is configured by a microcomputer or the like. In the control unit 100, the number of images set in the printing machine 1, the number of rotations of the saw cylinder 711 and the receiving cylinder 712 in the cutting apparatus 7, and a sensor (not shown) provided between the cutting apparatus 7 and the stacking apparatus 8 are illustrated. Etc.), a predetermined number of sheets S to be stacked on the mounting table 81 is input. The control unit 100 also includes a printing speed in the printing apparatus 4, a rotation speed of the saw cylinder 711 and the receiving cylinder 712 corresponding to the cutting speed of the cutting apparatus 7, and a conveyance speed of the cutting downstream conveyance section 73 in the cutting apparatus 7. From the above, the feeding speed of the sheet S to be sent to the mounting table 81 is input. In the control unit 100, the rotational speed information of the folding cylinder 1011 determined by the ratio between the sheet S feeding speed and the predetermined number of sheets S is stored in advance, and the rotational speed is based on the rotational speed information. The number of rotations of the motor M that rotationally drives the folding cylinder 1011 is controlled. Note that the saddle cylinder 1012 is driven by the motor M of the folding cylinder 1011 so that the rotation is synchronized with the folding cylinder 1011. Therefore, by controlling the rotation speed of the motor M of the folding cylinder 1011, the rotation speed of the rod cylinder 1012 synchronized with the folding cylinder 1011 can also be controlled.
　続いて、折り装置５の詳細な動作について説明する。図３～図１１は、折機の動作図である。ここでは、折り装置５における重ね装置８、搬送装置９及び第一折畳部１０１の動作を説明する。 Subsequently, the detailed operation of the folding device 5 will be described. 3 to 11 are operation diagrams of the folding machine. Here, operation | movement of the stacking apparatus 8, the conveying apparatus 9, and the 1st folding part 101 in the folding apparatus 5 is demonstrated.
　図３に示すように、重ね装置８では、載置台８１が上昇した位置にあり、この載置台８１の載置面８１ａに、断裁装置７により断裁されたシートＳが一枚ずつ送られ、位置決部８２の突当面８２ａに突き当たって位置決めされながら重ねられる。なお、このとき、第一折畳部１０１の折胴１０１１及び咥胴１０１２は、共に同期して回転している。 As shown in FIG. 3, in the stacking device 8, the mounting table 81 is in a raised position, and the sheets S cut by the cutting device 7 are sent to the mounting surface 81 a of the mounting table 81 one by one. It is piled up while being positioned by abutting against the abutting surface 82a of the determining portion 82. At this time, the folding cylinder 1011 and the rod cylinder 1012 of the first folding unit 101 are both rotated in synchronization.
　図４に示すように、載置台８１に重ねられたシートＳが予め設定された所定枚数に至った場合、載置台８１が搬送装置９の位置まで下降する。次に、搬送装置９の把持部９２によりシート群Ｓ’をつかむ。 As shown in FIG. 4, when the number of sheets S stacked on the mounting table 81 reaches a predetermined number, the mounting table 81 is lowered to the position of the conveying device 9. Next, the sheet group S ′ is grasped by the grip portion 92 of the transport device 9.
　図５に示すように、搬送装置９の回転部９１の回転により、把持部９２でつかまれているシート群Ｓ’の端部が第一折畳部１０１の折胴１０１１の胴部１０１１ａの周面に接近する。この搬送装置９の回転部９１の回転に同期して折胴１０１１は、保持部１０１１ｂがシート群Ｓ’の端部の位置に配置される。この所定位置において保持部１０１１ｂは、胴部１０１１ａの周面から外側に突出させた針によりシート群Ｓ’の端部を刺して保持する。なお、このとき、シート群Ｓ’がなくなった載置台８１は上昇する。 As shown in FIG. 5, the end portion of the sheet group S ′ held by the grip portion 92 is rotated by the rotation portion 91 of the conveying device 9 so that the circumferential surface of the body portion 1011 a of the folding cylinder 1011 of the first folding portion 101. To approach. In synchronism with the rotation of the rotation unit 91 of the conveying device 9, the holding unit 1011b of the folding cylinder 1011 is disposed at the end position of the sheet group S '. In this predetermined position, the holding portion 1011b stabs and holds the end portion of the sheet group S ′ with a needle protruding outward from the peripheral surface of the body portion 1011a. At this time, the mounting table 81 where the sheet group S ′ has been removed rises.
　図６～図９に示すように、折胴１０１１の回転に伴い、保持部１０１１ｂに保持されたシート群Ｓ’は、胴部１０１１ａの周面に巻き付くようにして送られる。その間、図６に示すように、上昇した載置台８１には、断裁装置７により断裁されたシートＳが位置決めされながら重ねられる。そして、図７に示すように、載置台８１に重ねられたシートＳが予め設定された所定枚数に至った場合、載置台８１が搬送装置９の位置まで下降し、搬送装置９の把持部９２によりシート群Ｓ’をつかむ。さらに、図８に示すように、搬送装置９の回転部９１の回転により、把持部９２でつかまれているシート群Ｓ’の端部を第一折畳部１０１の折胴１０１１の胴部１０１１ａの周面に接近させ、折胴１０１１のもう一つの保持部１０１１ｂによりシート群Ｓ’の端部を保持する。そして、シート群Ｓ’がなくなった載置台８１は上昇し、図９に示すように、断裁装置７により断裁されたシートＳが位置決めされながら重ねられる。このように、本実施の形態の折り装置５では、順次、断裁されたシートＳを重ねたシート群Ｓ’を折胴１０１１に搬送しつつ折胴１０１１に保持させている。 As shown in FIGS. 6 to 9, as the folding cylinder 1011 rotates, the sheet group S ′ held by the holding part 1011b is fed so as to be wound around the circumferential surface of the cylinder part 1011a. Meanwhile, as shown in FIG. 6, the sheet S cut by the cutting device 7 is superimposed on the elevated mounting table 81 while being positioned. As shown in FIG. 7, when the number of sheets S stacked on the mounting table 81 reaches a predetermined number, the mounting table 81 is lowered to the position of the transport device 9, and the grip portion 92 of the transport device 9. To grasp the sheet group S ′. Further, as shown in FIG. 8, the rotation of the rotation unit 91 of the conveying device 9 causes the end of the sheet group S ′ held by the gripping unit 92 to be moved to the body 1011 a of the folding cylinder 1011 of the first folding unit 101. The end portion of the sheet group S ′ is held by another holding portion 1011b of the folding cylinder 1011 so as to approach the peripheral surface. Then, the mounting table 81 where the sheet group S ′ has disappeared moves up, and the sheets S cut by the cutting device 7 are stacked while being positioned, as shown in FIG. 9. As described above, in the folding device 5 of the present embodiment, the sheet group S ′ on which the cut sheets S are sequentially stacked is conveyed to the folding cylinder 1011 and is held by the folding cylinder 1011.
　図１０に示すように、折胴１０１１及び咥胴１０１２の同期回転により、折ブレード１０１１ｃと咥機構１０１２ｂとが対向する所定位置に到達した場合、折ブレード１０１１ｃが胴部１０１１ａの周面の外側に突出する。すると、折ブレード１０１１ｃによりシート群Ｓ’の一部（中央部）が押し出されつつ咥機構１０１２ｂにより咥えられる。これにより、折ブレード１０１１ｃにより押し出されたシート群Ｓ’の一部（中央部）が咥機構１０１２ｂにより咥えられて折り目となって横折りされる。なお、このとき、保持部１０１１ｂは、針を胴部１０１１ａの周面の内側に待避させてシート群Ｓ’の端部の保持を解除する。 As shown in FIG. 10, when the folding blade 1011c and the saddle mechanism 1012b reach a predetermined position by the synchronous rotation of the folding cylinder 1011 and the saddle cylinder 1012, the folding blade 1011c is placed outside the peripheral surface of the trunk portion 1011a. Protruding. Then, a part (center part) of the sheet group S ′ is pushed out by the folding mechanism 1012 b while being pushed out by the folding blade 1011 c. As a result, a part (center portion) of the sheet group S ′ pushed out by the folding blade 1011 c is held by the folding mechanism 1012 b and is folded horizontally as a fold. At this time, the holding unit 1011b releases the holding of the end portion of the sheet group S ′ by retracting the needle inside the circumferential surface of the body unit 1011a.
　図１１に示すように、咥胴１０１２の回転により、咥機構１０１２ｂにより咥えられた状態でシート群Ｓ’を送る。そして、シート群Ｓ’が第二折畳部１０２のコンベア１０２２に接近した位置に至った所定位置で咥機構１０１２ｂによるシート群Ｓ’の咥えを開放し、このシート群Ｓ’を第二折畳部１０２に受け渡す。なお、第二折畳部１０２では、上述したようにシート群Ｓ’がさらに縦折りされて折帖とされる。 As shown in FIG. 11, the sheet group S ′ is fed in a state of being gripped by the saddle mechanism 1012 b by the rotation of the saddle drum 1012. Then, the sheet group S ′ is opened by the saddle mechanism 1012b at a predetermined position where the sheet group S ′ reaches the position close to the conveyor 1022 of the second folding unit 102. Delivered to the tatami mat unit 102. In the second folding unit 102, as described above, the sheet group S 'is further folded vertically to form a fold.
　なお、上述した折り装置５の動作において、重ね装置８の載置台８１は、昇降可能に構成され、載置面８１ａに重ねられたシートＳが予め設定された所定枚数に至った場合、搬送装置９の位置まで下降するが、この限りではない。例えば、載置台８１が固定されており、搬送装置９がシート群Ｓ’をつかむ位置に配置され、載置面８１ａに重ねられたシートＳが予め設定された所定枚数に至った場合、位置決部８２を待避させつつ把持部９２によりシート群Ｓ’をつかむように構成してもよい。 In the operation of the folding device 5 described above, the mounting table 81 of the stacking device 8 is configured to be movable up and down, and when the sheet S stacked on the mounting surface 81a reaches a predetermined number of sheets, the transport device Although it falls to the position of 9, it is not limited to this.
