Description

折り目入れ折り装置Folding and folding device
　本発明は、用紙に折り目を入れて、その折り目に沿って用紙を折るように構成された折り目入れ折り装置に関するものである。 The present invention relates to a crease and fold device configured to crease a sheet and fold the sheet along the crease.
　折り目入れ折り装置は、用紙に折り目を入れて、その折り目に沿って用紙を折るように構成されている。従来の折り目入れ折り装置は、例えば特許文献１の通り、用紙に折り目を入れるための折り目入れ機構と、折り目入れ機構から搬送される用紙を折り目に沿って折るための折り機構と、折り目入れ機構および折り機構の動作を制御するための制御部と、を備えている。 The crease and fold device is configured to crease a sheet and fold the sheet along the crease. A conventional crease and fold device includes, for example, a crease mechanism for folding a sheet, a fold mechanism for folding a sheet conveyed from the crease mechanism, and a crease mechanism as disclosed in Patent Document 1. And a control unit for controlling the operation of the folding mechanism.
　折り目入れ機構は、用紙を搬送するための搬送ローラと、搬送ローラによって搬送された用紙に折り目を入れるための折り目入れ部と、を備えている。折り機構は、先端で折り目入れ機構から搬送される用紙を折り目に沿って押すための折ナイフと、所定の間隔を置いて互いに平行に配置され、折ナイフの先端が間隔に対向するように配置された一対の折ローラと、を備えている。そして、折ナイフによって押された用紙が折ローラの間隔に導入されることで、用紙が折り目に沿って折られる。 The crease setting mechanism includes a conveyance roller for conveying the sheet and a crease unit for folding the sheet conveyed by the conveyance roller. The folding mechanism is arranged in parallel with each other with a folding knife for pushing the paper conveyed from the folding mechanism at the tip along the crease, and arranged so that the tip of the folding knife faces the gap. A pair of folding rollers. Then, the sheet pushed by the folding knife is introduced into the interval between the folding rollers, so that the sheet is folded along the crease.
　ところで、用紙に折り目を入れて、その折り目に沿って用紙を折るとき、図１６（Ａ）の通り、折り目の窪み部を折ナイフの先端で押して、折り目に沿って用紙を折る場合と、図１６（Ｂ）の通り、折り目の突出部を折ナイフの先端で押して、折り目に沿って用紙を折る場合とがある。
　用紙が厚紙の場合には、図１６（Ａ）の通り、折り目と同じ方向に用紙を折ると、用紙が開いて、綺麗に折ることができない。そのため、用紙が厚紙の場合には、図１６（Ｂ）の通り、用紙が開かないように、折り目と逆方向に用紙を折る。
　また、用紙が薄紙の場合には、折り目と逆方向に用紙を折ると、用紙の折り部が膨らんで綺麗に折ることができない。そのため、用紙が薄紙の場合には、用紙の折り部が膨らまないように、折り目と同じ方向に用紙を折る。 By the way, when a sheet is creased and the sheet is folded along the crease, as shown in FIG. 16 (A), the depression of the crease is pushed with the tip of the folding knife and the sheet is folded along the crease. As shown in FIG. 16B, the sheet may be folded along the crease by pushing the protruding part of the crease with the tip of the folding knife.
When the paper is thick, as shown in FIG. 16A, if the paper is folded in the same direction as the fold, the paper opens and cannot be folded neatly. Therefore, when the paper is thick, as shown in FIG. 16B, the paper is folded in the direction opposite to the fold so that the paper does not open.
In addition, when the paper is thin, if the paper is folded in the direction opposite to the fold, the folded portion of the paper swells and cannot be folded neatly. Therefore, when the paper is thin, the paper is folded in the same direction as the fold so that the folded portion of the paper does not swell.
　従来の折り目入れ折り装置では、折り目入れ部は、用紙の一方面側に配置された凸部と、用紙の他方面側に配置された凹部と、を備え、凸部および凹部を互いに近づけることで、用紙の一方面が窪み、用紙の他方面が突出した折り目が形成される。このように、折り目入れ部は、１組の凸部および凹部を備えているだけなので、用紙の一方面が窪み、用紙の他方面が突出した１種類の折り目しか形成できない。 In the conventional crease and fold device, the crease portion includes a convex portion disposed on one side of the paper and a concave portion disposed on the other side of the paper, and the convex portion and the concave portion are brought close to each other. A crease is formed in which one side of the paper is recessed and the other side of the paper protrudes. As described above, the crease forming portion only includes a pair of convex portions and concave portions, so that only one type of crease in which one surface of the paper is recessed and the other surface of the paper protrudes can be formed.
　従来の折り目入れ折り装置では、折り機構は、先ず、第１の折ナイフが用紙の他方面から折り目を押して、次に、第２の折ナイフが用紙の一方面から折り目を押して、２回用紙を折る。そのため、用紙は、第１の折ナイフでは折り目と逆方向に折られるが、（図１６（Ｂ）参照）、第２の折ナイフでは折り目と同じ方向に折られる（図１６（Ａ）参照）。その結果、用紙が厚紙の場合には、第２の折ナイフで折り目と同じ方向に折られた用紙の折り部が開いて（図１６（Ａ）参照）、綺麗に折ることができなかった。また、用紙が薄紙の場合には、第１の折ナイフで折られた用紙の折り部が膨らんで、綺麗に折ることができなかった。 In the conventional crease and folding device, the folding mechanism is such that the first folding knife first pushes the crease from the other side of the paper, and then the second folding knife pushes the crease from the one side of the paper, and the paper is turned twice. Fold. Therefore, the sheet is folded in the direction opposite to the fold in the first folding knife (see FIG. 16B), but is folded in the same direction as the fold in the second folding knife (see FIG. 16A). . As a result, when the paper is thick paper, the folding portion of the paper folded in the same direction as the crease with the second folding knife opened (see FIG. 16A), and could not be folded neatly. In addition, when the paper is thin, the folded portion of the paper folded with the first folding knife swells and cannot be folded neatly.

　上記の通り、本発明に係る折り目入れ折り装置では、折り目入れ部は、用紙の搬送方向に沿って配置された第１折り目入れユニットおよび第２折り目入れユニットを備えている。第１折り目入れユニットは、用紙の一方面側に配置された第１凸部と、用紙の他方面側に配置された第１凹部と、を備え、第１凸部および第１凹部を互いに近づけることで、用紙の一方面が窪み、用紙の他方面が突出した第１折り目が形成される。第２折り目入れユニットは、用紙の一方面側に配置された第２凹部と、用紙の他方面側に配置された第２凸部と、を備え、第２凹部および第２凸部を互いに近づけることで、用紙の他方面が突出し、用紙の一方面が窪んだ第２折り目が形成される。 As described above, in the crease and fold device according to the present invention, the crease unit includes the first crease unit and the second crease unit arranged along the sheet conveyance direction. The first crease unit includes a first convex portion disposed on one side of the paper and a first concave portion disposed on the other side of the paper, and brings the first convex portion and the first concave portion closer to each other. As a result, a first fold is formed in which one side of the paper is recessed and the other side of the paper protrudes. The second crease unit includes a second concave portion disposed on one side of the paper and a second convex portion disposed on the other side of the paper, and brings the second concave portion and the second convex portion closer to each other. Thus, a second fold is formed in which the other side of the sheet protrudes and the one side of the sheet is recessed.
　折り機構の折ナイフが用紙の他方面から折り目を押すように構成されているとき、第１折り目入れユニットで折り目を入れると、用紙の他方面に折り目の突出部を形成できるので、折り目の突出部を折ナイフで押すことができる。したがって、厚紙の用紙を綺麗に折ることができる。また、このとき、第２折り目入れユニットで折り目を入れると、用紙の他方面に折り目の窪み部を形成できるので、折り目の窪み部を折ナイフで押すことができる。したがって、薄紙の用紙を綺麗に折ることができる。 When the folding knife of the folding mechanism is configured to push the crease from the other side of the paper, if the crease is made by the first crease unit, the crease protrusion can be formed on the other side of the paper. The part can be pushed with a folding knife. Therefore, it is possible to fold the thick paper neatly. At this time, if a crease is made by the second crease unit, a crease recess can be formed on the other side of the sheet, and therefore the crease recess can be pushed with a fold knife. Therefore, it is possible to fold thin paper neatly.
　上記の通り、本発明に係る折り目入れ折り装置では、第１折り目入れユニットおよび第２折り目入れユニットが、異なる向きの２組の凹部および凸部を備えており、異なる向きの折り目を用紙に形成できるので、折り目と同じ方向に折ナイフの先端が折り目を押す場合と折り目と逆方向に折ナイフの先端が折り目を押す場合との双方で用紙を折ることができ、用紙が厚紙であっても薄紙であっても、用紙を綺麗に折ることができる。 As described above, in the crease and fold device according to the present invention, the first crease unit and the second crease unit have two sets of concave portions and convex portions in different directions, and folds in different directions are formed on the paper. You can fold the paper both when the tip of the folding knife pushes the crease in the same direction as the fold and when the tip of the folding knife pushes the crease in the opposite direction to the fold. Even thin paper can be folded neatly.

When the position where the first fold line 400 is formed is disposed at the position of the first convex portion 40 and the first concave portion 41, the sheet S is stopped by the stop of the transport rollers 10 and 11. Then, the first concave portion 41 approaches the first convex portion 40, and the first fold 400 is formed on the paper S. In the first crease 400, one surface (upper surface) S1 of the paper S is recessed, and the other surface (lower surface) S2 of the paper S protrudes.
　その後、図３の通り、第２折り目５００を形成する位置が、第２凸部５０および第２凸部５１の位置に配置されるように、搬送ローラ１０，１１の回転量を制御して、用紙Ｓが搬送方向Ｆに搬送される。第２折り目５００を形成する位置が、第２凸部５０および第２凹部５１の位置に配置されると、搬送ローラ１０，１１の停止によって、用紙Ｓが停止される。そして、第２凸部５０が第２凹部５１に近づいて、用紙Ｓに第２折り目５００が形成される。第２折り目５００は、用紙Ｓの一方面（上面）Ｓ１が突出して、用紙Ｓの他方面（下面）Ｓ２が窪んでいる。 Thereafter, as shown in FIG. 3, the rotation amount of the transport rollers 10 and 11 is controlled so that the position where the second fold line 500 is formed is arranged at the position of the second convex part 50 and the second convex part 51, The sheet S is transported in the transport direction F.

　その後、図１０の通り、第１折り目４００を形成する位置が、第１凸部４０および第１凸部４１の位置に配置されるように、搬送ローラ１０，１１の回転量を制御して、用紙Ｓが搬送方向Ｆに搬送される。第１折り目４００を形成する位置が、第１凸部４０および第１凹部４１の位置に配置されると、搬送ローラ１０，１１の停止によって、用紙Ｓが停止される。そして、第１凹部４１が第１凸部４０に近づいて、用紙Ｓに第１折り目４００が形成される。第１折り目４００は、用紙Ｓの一方面（上面）Ｓ１が窪んで、用紙Ｓの他方面（下面）Ｓ２が突出している。 Thereafter, as shown in FIG. 10, the rotation amount of the transport rollers 10 and 11 is controlled so that the position where the first fold line 400 is formed is arranged at the position of the first convex portion 40 and the first convex portion 41. The sheet S is transported in the transport direction F. When the position where the first fold line 400 is formed is disposed at the position of the first convex portion 40 and the first concave portion 41, the sheet S is stopped by the stop of the transport rollers 10 and 11. Then, the first concave portion 41 approaches the first convex portion 40, and the first fold 400 is formed on the paper S. In the first crease 400, one surface (upper surface) S1 of the paper S is recessed, and the other surface (lower surface) S2 of the paper S protrudes.
　その後、図１１の通り、第２折り目５００が第１折ナイフ２３の先端２３ａの位置に配置されるように、搬送ローラ１１および第１折ローラ２０の回転量を制御して、用紙Ｓが搬送方向Ｆに搬送される。用紙Ｓは、第２搬送ローラ１１から排出されて、排出された用紙Ｓは、第１折ローラ２０および第１押えローラ２００に挟まれて送られる。このとき、第２折ローラ２１の逆方向の回転によって用紙Ｓが搬送方向Ｆと逆方向に搬送されないように、第２押えローラ２１０は第２折ローラ２１から離れている。第２折り目５００が第１折ナイフの先端２３ａの位置に配置されると、搬送ローラ１１、第１および第２折ローラ２０，２１の停止によって、用紙Ｓが停止される。 Thereafter, as shown in FIG. 11, the rotation amount of the conveying roller 11 and the first folding roller 20 is controlled so that the second fold 500 is arranged at the position of the tip 23 a of the first folding knife 23, and the sheet S is conveyed. It is conveyed in the direction F. The paper S is discharged from the second conveying roller 11, and the discharged paper S is sandwiched between the first folding roller 20 and the first pressing roller 200 and sent. At this time, the second pressing roller 210 is separated from the second folding roller 21 so that the sheet S is not conveyed in the direction opposite to the conveyance direction F by the rotation of the second folding roller 21 in the reverse direction. When the second fold line 500 is disposed at the position of the tip 23a of the first fold knife, the sheet S is stopped by the stop of the transport roller 11, the first and second fold rollers 20, 21.
　その後、図１２の通り、第２押えローラ２１０が第２折ローラ２１に近接して、第１折ナイフ２３が駆動する。そして、第１折ローラ２０が時計方向に回転し、第２折ローラが反時計方向に回転する。これによって、第１折ナイフ２３の先端２３ａが第２折り目５００を押して、第２折り目５００が、第１および第２折ローラ２０，２１の第１間隙２０１に導入される。したがって、第１折ナイフ２３の先端２３ａは、第２折り目５００の窪み部を押す。そして、第１間隙２０１に導入された用紙Ｓが、第２折り目５００に沿って折られて、第１および第２折ローラ２０，２１から排出される。これによって、用紙Ｓは、第２折り目５００と同じ方向に折られる。 Thereafter, as shown in FIG. 12, the second presser roller 210 comes close to the second folding roller 21 and the first folding knife 23 is driven. Then, the first folding roller 20 rotates in the clockwise direction, and the second folding roller rotates in the counterclockwise direction. As a result, the tip 23 a of the first folding knife 23 pushes the second fold 500, and the second fold 500 is introduced into the first gap 201 between the first and second folding rollers 20, 21. Therefore, the tip 23 a of the first folding knife 23 presses the recess of the second fold 500. Then, the sheet S introduced into the first gap 201 is folded along the second fold line 500 and discharged from the first and second folding rollers 20 and 21. As a result, the sheet S is folded in the same direction as the second fold line 500.
　その後、図１３の通り、第１折り目４００が第２折ナイフ２４の先端２４ａの位置に配置されるように、第１および第２折ローラ２０，２１の回転によって、用紙Ｓが搬送方向Ｆ’に配送される。搬送方向Ｆ’は、搬送方向Ｆに対してほぼ直角方向に向いている。このとき、第３折ローラ２２の逆方向の回転によって用紙Ｓが搬送方向Ｆ’と逆方向に搬送されないように、第３押えローラ２２０は第３折ローラ２２から離れている。第１折り目４００が第２折ナイフ２４の先端２４ａに配置されると、第１および第２折ローラ２０，２１の停止によって、用紙Ｓが停止される。 Thereafter, as shown in FIG. 13, the sheet S is moved in the transport direction F ′ by the rotation of the first and second folding rollers 20 and 21 so that the first fold 400 is disposed at the position of the tip 24a of the second folding knife 24. Delivered to. The transport direction F ′ is directed substantially perpendicular to the transport direction F. At this time, the third pressing roller 220 is separated from the third folding roller 22 so that the sheet S is not conveyed in the direction opposite to the conveyance direction F ′ by the reverse rotation of the third folding roller 22. When the first fold 400 is disposed at the tip 24a of the second fold knife 24, the sheet S is stopped by the stop of the first and second fold rollers 20, 21.
　その後、図１４の通り、第３押えローラ２２０が第３折ローラ２２に近接して、第２折ナイフ２４が駆動する。そして、第１折ローラ２０が時計方向に回転し、第２折ローラが反時計方向に回転し、第３折ローラ２２が時計方向に回転する。これによって、第２折ナイフ２４の先端２４ａが第１折り目４００を押して、第１折り目５００が、第２および第３折ローラ２１，２２の第２間隙２０２に導入される。したがって、第２折ナイフ２４の先端２４ａは、第１折り目４００の窪み部を押す。そして、第２間隙２０２に導入された用紙Ｓが、第１折り目４００に沿って折られて、第２および第３折ローラ２１，２２から排出される。これによって、用紙Ｓは、第１折り目５００と同じ方向に折られる。 Thereafter, as shown in FIG. 14, the third presser roller 220 approaches the third folding roller 22, and the second folding knife 24 is driven. Then, the first folding roller 20 rotates in the clockwise direction, the second folding roller rotates in the counterclockwise direction, and the third folding roller 22 rotates in the clockwise direction. As a result, the tip 24 a of the second folding knife 24 pushes the first fold 400, and the first fold 500 is introduced into the second gap 202 of the second and third folding rollers 21 and 22. Therefore, the tip 24 a of the second folding knife 24 presses the recess of the first fold 400. Then, the sheet S introduced into the second gap 202 is folded along the first fold 400 and discharged from the second and third folding rollers 21 and 22. As a result, the sheet S is folded in the same direction as the first fold line 500.
　上記の動作によって、図１５の通り、用紙Ｓは、第１および第２折り目４００，５００に沿って折られる。このとき、上記の通り、本発明に係る装置は、厚紙の用紙Ｓを第１および第２折り目４００，５００と同じ方向に折ることができるので、用紙Ｓの折り部が膨らまずに綺麗に折られる。 By the above operation, as shown in FIG. 15, the sheet S is folded along the first and second fold lines 400 and 500. At this time, as described above, the apparatus according to the present invention can fold the thick paper S in the same direction as the first and second folds 400 and 500, so that the folded portion of the paper S is folded neatly without swelling. It is done.
