Description

この発明は、段ボールシート等のシートを送るシート送り装置に関する。   The present invention relates to a sheet feeding device for feeding a sheet such as a cardboard sheet.

段ボールシートに印刷を施す印刷機は、一般に、上下一対の送りローラからなるシート送り装置で段ボールシートを版胴に送るようにしている。しかし、段ボールシートにシート送り方向と直角方向の罫線があると、その罫線の位置で送りローラが段ボールシートを挟むニップ圧が低くなり、段ボールシートの送りが不安定になって、印刷にずれを生じる。   In general, a printing machine that performs printing on a corrugated cardboard sheet feeds the corrugated cardboard sheet to a plate cylinder by a sheet feeding device including a pair of upper and lower feed rollers. However, if the cardboard sheet has a ruled line perpendicular to the sheet feeding direction, the nip pressure at which the feeding roller sandwiches the cardboard sheet at the position of the ruled line becomes low, the cardboard sheet feed becomes unstable, and printing is displaced. Arise.

この印刷ずれを防止するために、図７（ａ）に示すように上下一対の送りローラをシート送り方向に２列配置し、その送りローラで、送り出し装置３０から送り出された段ボールシート３１を挟んで印刷機の版胴３２と圧胴３３の間に送り込むようにしたシート送り装置が知られている。このシート送り装置においては、段ボールシート３１の表面が罫線３１ａの位置で一方の列の送りローラ３４、３５から離れても、他方の列の送りローラ３６、３７が段ボールシート３１を挟んでいるので、段ボールシート３１を精度よく送ることができる。   In order to prevent this printing misalignment, as shown in FIG. 7A, a pair of upper and lower feed rollers are arranged in two rows in the sheet feeding direction, and the corrugated sheet 31 fed from the feeding device 30 is sandwiched between the feeding rollers. There is known a sheet feeding apparatus that feeds between a plate cylinder 32 and an impression cylinder 33 of a printing press. In this sheet feeding apparatus, even if the surface of the corrugated cardboard sheet 31 is separated from the feeding rollers 34 and 35 in one row at the position of the ruled line 31a, the feeding rollers 36 and 37 in the other row sandwich the corrugated cardboard sheet 31. The cardboard sheet 31 can be fed with high accuracy.

しかし、図７（ｂ）に示すように罫線３１ａが段ボールシート３１の前端付近にあると、下流側の送りローラ３６、３７が段ボールシート３１の前端を挟み込む前に、段ボールシート３１の罫線３１ａが上流側の送りローラ３４、３５と対向して、段ボールシート３１の送りが不安定になる。また、段ボールシート３１の後端付近に罫線がある場合も、上流側の送りローラ３４、３５が段ボールシートの後端を送り出した後に、段ボールシート３１の罫線３１ａが下流側の送りローラ３６、３７と対向して、段ボールシート３１の送りが不安定になる。   However, if the ruled line 31 a is near the front end of the cardboard sheet 31 as shown in FIG. 7B, the ruled line 31 a of the cardboard sheet 31 is moved before the downstream feed rollers 36 and 37 sandwich the front end of the cardboard sheet 31. The feed of the corrugated cardboard sheet 31 becomes unstable facing the upstream feed rollers 34 and 35. Further, even when there is a ruled line near the rear end of the corrugated cardboard sheet 31, after the upstream feed rollers 34 and 35 send out the rear end of the cardboard sheet 31, the ruled line 31 a of the corrugated cardboard sheet 31 becomes the downstream feed rollers 36 and 37. The feeding of the cardboard sheet 31 becomes unstable.

この問題は、送りローラのローラ径を小さくして、上流側の送りローラと下流側の送りローラの設置間隔を小さくすることによって解消することができるが、ローラ径が小さくなると送りローラがたわんで共振しやすくなるので、ローラ径を必要以上に小さくすることができない。   This problem can be solved by reducing the roller diameter of the feed roller and reducing the installation interval between the upstream feed roller and the downstream feed roller. However, if the roller diameter is reduced, the feed roller bends. Since it becomes easy to resonate, the roller diameter cannot be made smaller than necessary.

そこで、この従来のシート送り装置では、図７（ａ）（ｂ）に示すように、上流側の送りローラ３４、３５を下流側の送りローラ３６、３７の間に入り込ませることによって、上流側の送りローラ３４、３５と下流側の送りローラ３６、３７の設置間隔を小さくしているが、この設置間隔は、上流側の送りローラ３４、３５と下流側の送りローラ３６、３７とが互いに干渉しない範囲でしか小さくすることができない。そのため、このシート送り装置を用いても、段ボールシート３１の前端付近または後端付近に罫線３１ａがあると段ボールシート３１を精度よく送ることができなかった。   Therefore, in this conventional sheet feeding apparatus, as shown in FIGS. 7A and 7B, the upstream-side feeding rollers 34 and 35 are inserted between the downstream-side feeding rollers 36 and 37, so that the upstream side The installation interval between the feed rollers 34 and 35 and the downstream feed rollers 36 and 37 is reduced, but the installation interval between the upstream feed rollers 34 and 35 and the downstream feed rollers 36 and 37 is mutually reduced. It can only be reduced within the range where it does not interfere. Therefore, even if this sheet feeding device is used, if the ruled line 31a is near the front end or the rear end of the cardboard sheet 31, the cardboard sheet 31 cannot be fed accurately.

この発明は、シートの前端付近または後端付近に罫線があるときにも、そのシートを精度よく送れるようにすることを課題とする。   It is an object of the present invention to make it possible to feed a sheet with high accuracy even when there are ruled lines near the front end or the rear end of the sheet.

上記の課題を解決するために、上下一対の送りローラからなるローラユニットをシート送り方向に対して直角方向に間隔をあけて複数設け、その隣り合うローラユニットをシート送り方向に互いにずらして配置し、前記複数のローラユニットの上側の送りローラを同時に回転させる上側ローラ駆動手段と、前記複数のローラユニットの下側の送りローラを同時に回転させる下側ローラ駆動手段とを設け、回転する上側の前記送りローラと下側の前記送りローラでシートを挟んで送る構成を採用した。   In order to solve the above problems, a plurality of roller units composed of a pair of upper and lower feed rollers are provided at intervals in a direction perpendicular to the sheet feeding direction, and the adjacent roller units are arranged to be shifted from each other in the sheet feeding direction. An upper roller driving means for simultaneously rotating the upper feed rollers of the plurality of roller units; and a lower roller driving means for simultaneously rotating the lower feed rollers of the plurality of roller units. A configuration is adopted in which the sheet is sandwiched between the feed roller and the lower feed roller.

この構成の段ボール送り装置は、シート送り方向に対して直角方向に隣り合うローラユニットが互いに分かれているので、その隣り合うローラユニットのシート送り方向のずれ量を自由に設定することができる。そのため、シートの前端付近または後端付近に罫線があるときにも、隣り合うローラユニットのシート送り方向のずれ量を、シートの前端または後端から罫線までの距離よりも小さく設定することによってシートを精度よく送ることができる。   In the corrugated cardboard feeding device having this configuration, the roller units adjacent to each other in the direction perpendicular to the sheet feeding direction are separated from each other, so that the deviation amount of the adjacent roller units in the sheet feeding direction can be freely set. Therefore, even when there is a ruled line near the front edge or the rear edge of the sheet, the deviation amount in the sheet feeding direction of the adjacent roller unit is set smaller than the distance from the front edge or the rear edge of the sheet to the ruled line. Can be sent accurately.

前記上側ローラ駆動手段は、前記上側の送りローラと平行に設けた上回転駆動軸と、その上回転駆動軸の回転を前記上側のそれぞれの送りローラに伝達するトルク伝達手段とで構成すると好ましい。このようにしたものは、上側のそれぞれの送りローラが共通の上回転駆動軸で駆動されるので、上側のそれぞれの送りローラの回転速度が一致し、シートをより精度よく送ることができる。   The upper roller driving means is preferably constituted by an upper rotation driving shaft provided in parallel with the upper feeding roller and torque transmitting means for transmitting the rotation of the upper rotation driving shaft to the upper feeding rollers. In this configuration, the upper feed rollers are driven by a common upper rotation drive shaft, so that the rotational speeds of the upper feed rollers coincide with each other, and the sheet can be fed more accurately.

さらに、前記複数のローラユニットを、交互にシート送り方向にずれる千鳥状の配置とし、上流側に位置する上側の送りローラと下流側に位置する上側の送りローラの中間の上方に前記上回転駆動軸を配置したものは、送りローラと上回転駆動軸とが上下に並ぶので、シート送り方向の設置スペースが小さく済み、フレキソフォルダグルア等の印刷機ユニットへの組み込みが容易である。   Further, the plurality of roller units are arranged in a staggered manner that are alternately shifted in the sheet feeding direction, and the upper rotational drive is performed above the middle of the upper feeding roller located on the upstream side and the upper feeding roller located on the downstream side. In the case where the shaft is arranged, the feed roller and the upper rotation drive shaft are arranged vertically, so that the installation space in the sheet feed direction is small, and it is easy to incorporate into a printing press unit such as a flexo folder gluer.

同様に、前記下側ローラ駆動手段は、前記下側の送りローラと平行に設けた下回転駆動軸と、その下回転駆動軸の回転を前記下側のそれぞれに伝達するトルク伝達手段とで構成すると好ましく、さらに、前記複数のローラユニットを、交互にシート送り方向にずれる千鳥状の配置とし、上流側に位置する下側の送りローラと下流側に位置する下側の送りローラの中間の下方に前記下回転駆動軸を配置するとより好ましい。   Similarly, the lower roller driving means includes a lower rotation drive shaft provided in parallel with the lower feed roller, and torque transmission means for transmitting the rotation of the lower rotation drive shaft to the lower side. Preferably, the plurality of roller units are arranged in a zigzag pattern so as to be alternately shifted in the sheet feeding direction, and below the middle between the lower feeding roller located on the upstream side and the lower feeding roller located on the downstream side. More preferably, the lower rotary drive shaft is disposed in

この発明のシート送り装置は、シート送り方向に対して直角方向に隣り合うローラユニットのシート送り方向のずれ量を自由に設定することができるので、シートの前端付近または後端付近に罫線があるときにも、そのシートを精度よく送ることができる。   In the sheet feeding apparatus according to the present invention, since the deviation amount in the sheet feeding direction of the roller units adjacent to each other in the direction perpendicular to the sheet feeding direction can be freely set, there is a ruled line near the front end or the rear end of the sheet. Sometimes, the sheet can be sent with high accuracy.

図１に、この発明のシート送り装置の実施形態を示す。この装置は、上下一対の送りローラ１、２からなる複数のローラユニット３を有する。このローラユニット３は、段ボールシートの送り出し装置４から送り出された段ボールシート５を挟んで印刷機の版胴６と圧胴７の間に送り込む。   FIG. 1 shows an embodiment of the sheet feeding apparatus of the present invention. This apparatus has a plurality of roller units 3 composed of a pair of upper and lower feed rollers 1 and 2. The roller unit 3 feeds between the plate cylinder 6 and the impression cylinder 7 of the printing press with the cardboard sheet 5 fed from the cardboard sheet feeding device 4 interposed therebetween.

ローラユニット３はそれぞれ、図２に示すようにシート送り方向に対して直角方向に間隔をあけて配置されており、隣り合うローラユニット３、３がそれぞれ、シート送り方向に互いにずれるように配置されている。そのシート送り方向のずれ量は、シート前端またはシート後端から罫線５ａまでの距離が最も短い段ボールシートのその距離よりも小さく設定されている。そのため、いずれの段ボールシート５についても、図３に示すように罫線５ａが上流側の送りローラ１、２と対向するときは、下流側の送りローラ１、２で挟まれており、また、罫線５ａが下流側の送りローラ１、２と対向するときは、上流側の送りローラ１、２で挟まれており、安定して送られる。   As shown in FIG. 2, the roller units 3 are arranged at intervals in the direction perpendicular to the sheet feeding direction, and the adjacent roller units 3 and 3 are arranged so as to be shifted from each other in the sheet feeding direction. ing. The amount of deviation in the sheet feeding direction is set smaller than that of the corrugated cardboard sheet having the shortest distance from the sheet front end or sheet rear end to the ruled line 5a. Therefore, in any of the corrugated cardboard sheets 5, as shown in FIG. 3, when the ruled line 5a faces the upstream feed rollers 1 and 2, the cardboard sheet 5 is sandwiched between the downstream feed rollers 1 and 2, and the ruled line When 5a opposes the downstream feed rollers 1 and 2, it is sandwiched between the upstream feed rollers 1 and 2, and is stably fed.

上側の送りローラ１は、図４に示すように上ステー８でそれぞれ回転可能に支持されており、その一端にギア９が設けられている。また上ステー８には、上側の送りローラ１と平行な上回転駆動軸１０が回転可能に設けられており、この上回転駆動軸１０には、上側の送りローラ１のギア９と噛み合うギア１１が設けられている。上回転駆動軸１０は、駆動装置（図示せず）で駆動されて回転するようになっており、上回転駆動軸１０が回転すると、その回転運動がギア１１、９を介して上側の送りローラ１にそれぞれ伝わってその送りローラ１を同時に回転させる。そのため、上側のそれぞれの送りローラ１の回転速度が一致し、段ボールシート５がより精度よく送られる。   As shown in FIG. 4, the upper feed roller 1 is rotatably supported by an upper stay 8, and a gear 9 is provided at one end thereof. The upper stay 8 is rotatably provided with an upper rotation drive shaft 10 parallel to the upper feed roller 1. The upper rotation drive shaft 10 has a gear 11 that meshes with the gear 9 of the upper feed roller 1. Is provided. The upper rotary drive shaft 10 is driven to rotate by a driving device (not shown), and when the upper rotary drive shaft 10 rotates, the rotational motion is transferred to the upper feed roller via the gears 11 and 9. 1 and the feed roller 1 are simultaneously rotated. Therefore, the rotational speeds of the upper feed rollers 1 coincide with each other, and the cardboard sheet 5 is fed with higher accuracy.

また、上側のそれぞれの送りローラ１は、上ステー８で個別に支持されているのでたわみにくい。そのため、上側の送りローラ１が共振しにくく、段ボールシート５を高速で送るときにも送りの精度がよい。   Further, since each upper feed roller 1 is individually supported by the upper stay 8, it is difficult to bend. For this reason, the upper feed roller 1 is unlikely to resonate and the feeding accuracy is good even when the cardboard sheet 5 is fed at high speed.

上ステー８は、上下方向に移動可能にフレーム１２に取り付けられている。このフレーム１２には、図５に示すように上ステー８と接触する調整カム１３が回転可能に設けられており、調整カム１３を駆動装置（図示せず）で回転させると、その調整カム１３が上ステー８を押し動かして上下方向に移動させる。このとき、上側の送りローラ１が上ステー８と一緒に移動するので、上側の送りローラ１と下側の送りローラ２の間の隙間の大きさが変化する。このようにして、上側の送りローラ１と下側の送りローラ２の間の隙間の大きさを変えることができ、その隙間の大きさを段ボールシート５の厚みや反りの状態に応じて調整することによって、段ボールシート５をより精度よく送ることができる。   The upper stay 8 is attached to the frame 12 so as to be movable in the vertical direction. As shown in FIG. 5, the frame 12 is provided with an adjustment cam 13 that contacts the upper stay 8 in a rotatable manner. When the adjustment cam 13 is rotated by a drive device (not shown), the adjustment cam 13 is rotated. Pushes and moves the upper stay 8 to move it up and down. At this time, since the upper feed roller 1 moves together with the upper stay 8, the size of the gap between the upper feed roller 1 and the lower feed roller 2 changes. In this way, the size of the gap between the upper feed roller 1 and the lower feed roller 2 can be changed, and the size of the gap is adjusted according to the thickness of the corrugated cardboard sheet 5 and the state of warping. As a result, the corrugated cardboard sheet 5 can be fed more accurately.

上回転駆動軸１０は上ステー８で支持されており、調整カム１３を回転させて上側の送りローラ１を上下方向に移動させたときに、上回転駆動軸１０が一緒に移動してギア１１とギア９の噛み合いを維持するようになっている。   The upper rotation drive shaft 10 is supported by the upper stay 8, and when the adjustment cam 13 is rotated to move the upper feed roller 1 in the vertical direction, the upper rotation drive shaft 10 moves together to move the gear 11. And the meshing of the gear 9 is maintained.

下側の送りローラ２も、図４に示すようにそれぞれ下ステー１４で回転可能に支持されており、一端にギア１５が設けられている。このギア１５は、下側の送りローラ２と平行に配置された下回転駆動軸１６のギア１７と噛み合っている。そのため、下回転駆動軸１６を駆動装置（図示せず）で回転させると下側の送りローラ２がそれぞれ同時に回転する。下ステー１４は、両端がフレーム１２に固定されている。   The lower feed roller 2 is also rotatably supported by the lower stay 14 as shown in FIG. 4, and a gear 15 is provided at one end. This gear 15 meshes with a gear 17 of a lower rotary drive shaft 16 arranged in parallel with the lower feed roller 2. Therefore, when the lower rotation drive shaft 16 is rotated by a drive device (not shown), the lower feed rollers 2 are simultaneously rotated. Both ends of the lower stay 14 are fixed to the frame 12.

このように、下側のそれぞれの送りローラ２も、下ステー１４で個別に支持されているのでたわみにくい。そのため、下側の送りローラ２が共振しにくく、段ボールシート５を高速で送るときにも送りの精度がよい。   In this way, the lower feed rollers 2 are also individually supported by the lower stay 14 and thus are not easily bent. Therefore, the lower feeding roller 2 is less likely to resonate, and the feeding accuracy is good even when the cardboard sheet 5 is fed at high speed.

ローラユニット３は、図６に示すようにシート送り方向に交互にずれる千鳥状の配置とし、図５に示すように上流側に位置する送りローラ１と下流側に位置する送りローラ１の中間の上方に上回転駆動軸１０を配置すると好ましい。このようにすると、送りローラ１と上回転駆動軸１０が上下に並ぶので、シート送り装置のシート送り方向の設置スペースが小さく済み、フレキソフォルダグルア等の印刷機ユニットへの組み込みが容易となる。また、上側のそれぞれの送りローラ１と上回転駆動軸１０との軸心間距離が統一されるので、上回転駆動軸１０と上側のそれぞれの送りローラ１とを連結するギアを共通化して、メンテナンス性と経済性をともに向上させることができる。   As shown in FIG. 6, the roller unit 3 has a staggered arrangement that is alternately shifted in the sheet feeding direction, and is intermediate between the feeding roller 1 located on the upstream side and the feeding roller 1 located on the downstream side as shown in FIG. It is preferable to dispose the upper rotation drive shaft 10 above. In this way, since the feed roller 1 and the upper rotational drive shaft 10 are arranged vertically, the installation space in the sheet feeding direction of the sheet feeding device can be reduced, and it can be easily incorporated into a printing press unit such as a flexo folder gluer. Further, since the distance between the axial centers of the upper feed rollers 1 and the upper rotary drive shaft 10 is unified, the gears that connect the upper rotary drive shaft 10 and the upper feed rollers 1 are made common, Both maintainability and economy can be improved.

同様に、下回転駆動軸１６も、千鳥状に配置したローラユニット３の隣り合う送りローラ２、２の中間の下方に配置すると好ましい。   Similarly, the lower rotation drive shaft 16 is also preferably arranged below the middle of the adjacent feed rollers 2 and 2 of the roller units 3 arranged in a staggered manner.

ローラユニット３は、図では千鳥状の配置としているが、たとえば中央のローラユニットから遠いほど下流側にずれるＶ字状の配置としてもよく、シート送り方向に対して直角方向に隣り合うローラユニットがシート送り方向に互いにずれる配置であればよい。   The roller units 3 are arranged in a staggered pattern in the figure, but for example, they may be arranged in a V-shape that shifts to the downstream side as the distance from the central roller unit increases. Any arrangement that deviates in the sheet feeding direction may be used.

上回転駆動軸１０の回転を上側の送りローラ１に伝達するトルク伝達手段はギアに限定されない。たとえばチェーン、タイミングベルト、Ｖベルトなどで行なってもよい。下回転駆動軸１６の回転を下側の送りローラ２に伝達するトルク伝達手段についても同様である。   The torque transmission means for transmitting the rotation of the upper rotation drive shaft 10 to the upper feed roller 1 is not limited to a gear. For example, a chain, a timing belt, a V belt, or the like may be used. The same applies to the torque transmission means for transmitting the rotation of the lower rotation drive shaft 16 to the lower feed roller 2.

上記実施形態では、上側の送りローラ１と上回転駆動軸１０とをギアで連結して上側のそれぞれの送りローラ１を同時に回転させているが、たとえば送りローラごとにモータ等の駆動装置を設け、その駆動装置を同時に駆動することによって同時に回転させるようにしてもよい。このようにすれば、段ボールシート５の大きさに応じて送りローラ１を選択的に駆動し、部品の消耗を最小限に抑えることができる。下側の送りローラ２の駆動についても同様である。   In the above embodiment, the upper feed roller 1 and the upper rotational drive shaft 10 are connected by a gear and the upper feed rollers 1 are simultaneously rotated. For example, a drive device such as a motor is provided for each feed roller. The drive devices may be rotated simultaneously by driving them simultaneously. In this way, it is possible to selectively drive the feed roller 1 in accordance with the size of the corrugated cardboard sheet 5 and to minimize the consumption of parts. The same applies to the driving of the lower feed roller 2.

また、上記実施形態では、搬送するシートとして段ボールシートを挙げて説明したが、たとえば表面に溝が形成された樹脂シートなど、他のシートを搬送してもよい。   In the above-described embodiment, a corrugated cardboard sheet has been described as the sheet to be conveyed. However, other sheets such as a resin sheet having a groove formed on the surface may be conveyed.
