転されて搬出されるようになっていた。Rubber roll with high surface friction coefficient and high elasticity 01.0
2.03 are arranged in a V-shape in contact with each other, and from the lower side of the 10th-rule 01 to the 10th-rule 01 and the second
Loading chute 04 toward the contact area of 0-roe o2 and the 30th
20th-rule 02 and 30th-rule from the left side of
An unloading chute 05 facing the contact part of the second o-ru 03 is disposed, and a reversing chute 06 opening vertically downward is disposed directly above the second o-ru 02, and a stopper 07 is provided within the reversing chute 06. , the distance from the surface of the 20th-rule 02 to the stopper 07 is set slightly shorter than the length of the paper 08, and while rotating the 10th-rule 01, Ii and the 30th-rule 03 clockwise, 20
When the paper 08 is sent to the carry-in chute 04 with the -rule 02 rotated counterclockwise, the paper 08 is sandwiched between the 10th-rule 01 and the 20th-rule 02 and carried into the reversing chute 06. The rear end 08a of the sheet 08 is pushed upward by the frictional force with the 20th rule 02, causing the sheet 08 to buckle.
Due to the rotation of the 20th-rule 02 and the springback of the paper 08, the rear end 08a of the paper 08 is moved to the 20th-rule 02 and the 30th
The paper 08 is sandwiched between the paper rolls 03 and 03, and is inverted and delivered to the delivery chute 05.

このような従来の用紙反転装置においては、通常の用紙
についての反転機能にはなんら問題はないが、特別にカ
ール量の大きな用紙については問題がある。In such a conventional paper reversing device, there is no problem with the reversing function for normal paper, but there is a problem with paper that has a particularly large amount of curl.

がなされない不具合を生じる。That is, normally, the leading edge of the paper that is sandwiched between the 10th rule 01 and the 20th rule 02 and carried into the reversing chute 06 hits the stopper 07, causing buckling and the trailing edge 08
Due to the rotation of the 20th-rule 02 and the springback of the paper 08, the paper a moves to the contact area between the 20th-rule 02 and the 30th-rule 03, is reversed, and is conveyed out, but the paper with the largest curl In the case of 10th-rule 01 and 20th-rule 02
As a result, the curl formed on the paper is maintained when it is carried into the reversing chute 06, so that the springback due to buckling is weakened and the trailing edge 08a of the paper slides on the surface of the 20th-rule 02 and becomes the 20th-rule 02. It does not move to the contact area with No. 30-ru 03, but maintains the state shown in FIG. 3, causing a problem in which it is not turned over or carried out.
本発明はかかる点に鑑みなされたものでその目的とする

工芝9に把えられ、強制的に第20−ル2と第30−ル
3の接触部分に移動させられて両ロール2,3により搬
出される。Therefore, the trailing edge of the paper that is sandwiched between the 10th-rule 1 and the 2nd [1-2] and conveyed into the reversing chute 6 is gripped by the artificial turf 9, and is forced into the 20th-rule 2 and the 30th-rule. - moved to the contact area of roll 3 and carried out by both rolls 2, 3.
よって用紙のカール遣に関係なく反転が確実に行われる
。Therefore, reversal is performed reliably regardless of the curling of the paper.
第4図は第1臼−ル1と第20−ル2の接触した状態を
示す斜視図であり、両ロール1.2とも、軸方向4箇所
の対向する位置に溝が形成されており、第20−ル2の
該溝には表面に人工芝9を有するリング10が嵌着され
て第20−ル2と一体に回動できる。FIG. 4 is a perspective view showing a state in which the first milling roll 1 and the twentieth milling roll 2 are in contact, and both rolls 1.2 have grooves formed at four opposing positions in the axial direction. A ring 10 having artificial grass 9 on its surface is fitted into the groove of the 20th rule 2 and can rotate together with the 20th rule 2.
人工芝9の先端は溝以外のロール部分よりも外側に突出
しており、対向する第10−ル1の溝に嵌合する。The tip of the artificial turf 9 protrudes outward from the roll portion other than the groove, and fits into the groove of the opposing 10th rule 1.
第4図では省略したが第30−ル3についても第10−
ル1と同様で軸方向の4箇所に溝が形成され第2「1−
ル2の人工芝9と嵌合している。Although omitted in Figure 4, Section 30-3 also includes Section 10-3.
It is the same as 1-1, but grooves are formed at 4 locations in the axial direction.
It is fitted with the artificial turf 9 of Ru 2.
用紙反転機構を該3個のロール1,2.3の前記溝部分
における断面図(第5図)に基づいて説明する。The paper reversing mechanism will be explained based on a sectional view (FIG. 5) of the groove portions of the three rolls 1, 2.3.
第20−ル2は駆動ロールであり、上方および左方にお
いて接触する第1.第30−ル1.3は押えロールであ
る。The 20th roll 2 is a driving roll, and the 1st roll 2 is in contact with the upper and left sides. Rule 30-1.3 is a presser roll.
第20−ル2の溝に嵌着されたリング10の人工芝9が
第1、第30−ル1.3の溝に嵌合している。The artificial grass 9 of the ring 10 fitted into the groove of the 20th rule 2 is fitted into the grooves of the first and 30th rules 1.3.
第20−ル2が反時計回りに回転させられると、ロール
部分で接触した第1.第30−ル1,3は時計回りに回
転する。When the 20th wheel 2 is rotated counterclockwise, the first 20th wheel 2 is in contact with the roll portion. 30th-rules 1 and 3 rotate clockwise.
反転シュート6への用紙8の搬入は第10−ル1と第2

スI−ツバ−7により用紙8が押しドげられ、用紙8の
後端は第20−ル2の人工芝9の芝目に嵌まり込む。The paper 8 is carried into the reversing chute 6 by the 10th-rule 1 and the 2nd
[The paper 8 is sandwiched between the contact rolls of the 20th-rule 2, and the paper 8 is pushed away by the carry-in intrusion I-flange 7, and the trailing edge of the paper 8 touches the grass grain of the artificial turf 9 of the 20th-rule 2. get stuck in.
そして第2[1−ル2の回転により用紙の後端は第30
−ル3側に移動させられ、第20−ル2と第30−ル3
の接触[1一層部分に挟まれ反転搬出される。Then, due to the rotation of the second [1-2], the trailing edge of the paper is
- moved to the 3rd side, 20th - 2nd and 30th - 3rd
Contact [1] It is sandwiched between the first layer parts and is turned over and carried out.
したがってカール缶の大きな用紙であっても用紙後端は
スリップせずに人工芝の芝目に嵌まり込んで移動させら
れるので反転が確実になされる。Therefore, even if the paper is a large curled can, the trailing edge of the paper fits into the grain of the artificial turf without slipping and is moved, so that reversal is ensured.
本実施例では用紙後端のスリップを防止するため人工芝
を用いたが、第6図(1)、(2)に示すような電車形
状または水車形状をなすゴム等の弾性部材でできたリン
グを前記実施例のリングに替えて使用することもできる
。In this example, artificial turf was used to prevent the trailing edge of the paper from slipping, but a ring made of an elastic material such as rubber in the shape of a train or water wheel as shown in Fig. 6 (1) and (2) was used. It is also possible to use the ring in place of the ring in the above embodiment.
