Abstract

<P>PROBLEM TO BE SOLVED: To provide a paper feeder adaptable to various thicknesses of paper while adjusting the paper into an optimum shape depending on the thickness of the paper when sucked. <P>SOLUTION: The paper having a thin and soft cover can be sucked into a narrow recessed portion at the center of a table 1, and the sucked paper can be carried passing under a stopper 3 in the state of preventing the carriage of the after-second cover. On the other hand, the paper having a thick and hard cover can be largely deformed by enlarging the width of the recessed portion at the center of the table 1 with manual operation or the drive of a motor, and so it can be sucked by a suction part 4 so that the sucked cover 2a can be carried passing under the stopper 3. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

本発明は、テーブルに積載した用紙を下から順番に吸引して送り出す給紙装置に関する。   The present invention relates to a sheet feeding device that sucks and feeds sheets stacked on a table in order from the bottom.

印刷された一冊分の用紙束(本身)と表紙とを綴じ処理して製本する場合、この用紙束と表紙を無線綴じ処理を行う製本機や有線綴じ処理を行う用紙綴じ機が設置されている場所に運搬し、この製本機や用紙綴じ機により適宜に綴じ処理が行われる。一般的には一冊分の用紙束が厚いものに対しては製本機で、比較的に薄いものでは用紙綴じ機で綴じられて製本される。   When binding a bundle of printed sheets (the body) and the cover, a bookbinding machine that performs wireless binding and a sheet binding machine that performs wired binding is installed. It is transported to a place where it is present, and the binding process is appropriately performed by the bookbinding machine and the sheet binding machine. In general, a bookbinding machine is used for a thick sheet bundle, and a bookbinding machine is used for a relatively thin sheet bundle.

そして、上記のような製本機や用紙綴じ機では、一冊分の用紙束と表紙給紙装置に積載されている表紙がそれぞれ搬送されて用紙集積部で重ね合わされ、重ね合わされた一冊分の用紙束と表紙とが製本機あるいは用紙綴じ機に搬送され、糊を使用した無線綴じ処理あるいはステッチャーによる綴じ処理が行われる。このとき、表紙給紙装置として、積載した表紙を下から順番に吸引して送り出す給紙装置が使用されることがある(例えば、特許文献1参照)。   In the bookbinding machine and the sheet binding machine as described above, the sheet bundle for one book and the cover sheet loaded on the cover sheet feeding device are respectively transported and overlapped at the sheet stacking unit, and the overlapped one book is stored. A bundle of sheets and a cover are conveyed to a bookbinding machine or a sheet binding machine, and a wireless binding process using glue or a binding process by a stitcher is performed. At this time, as a cover sheet feeding apparatus, a sheet feeding apparatus that sucks and feeds the stacked covers in order from the bottom may be used (for example, see Patent Document 1).

特開2001−72269号公報JP 2001-72269 A

上記のようにテーブルに積載した用紙を下から順番に吸引して送り出す給紙装置においては、重送を防止する手段としてストッパを設けて吸引された用紙以外は搬送されないようにしている。そして、用紙の給紙時には、テーブルの中央の凹部に設けられた吸引部によって用紙が吸引されることにより通常の積載状態からストッパの下をくぐり抜けることができる位置に引き寄せられ一枚ずつ送り出される。
しかしながら、ストッパの下をくぐり抜けるためには、用紙の吸引される部分が若干変形する必要があるが、用紙の種類によっては変形の抵抗が大きくなるので、テーブルの中央の凹部が一定の形状では対応できる範囲が限られてしまう、という問題があった。
As described above, in the sheet feeding device that sucks and feeds the sheets stacked on the table in order from the bottom, a stopper is provided as a means for preventing double feeding so that only the sucked sheets are conveyed. When the paper is fed, the paper is sucked by a suction portion provided in the concave portion at the center of the table, so that the paper is drawn to a position where it can pass under the stopper from the normal stacking state and sent out one by one.
However, in order to pass under the stopper, it is necessary to slightly deform the sucked portion of the paper. However, depending on the type of paper, the deformation resistance increases, so the concave portion at the center of the table can be used with a fixed shape. There was a problem that the range that can be done was limited.

本発明は、上記の問題に鑑みてなされたもので、用紙吸引時の用紙形状を用紙の厚みに応じて最適な形状に調整可能であり、様々な厚みの用紙に対応することができる給紙装置を提供することを目的とする。   The present invention has been made in view of the above problems, and can adjust the paper shape at the time of paper suction to an optimal shape according to the thickness of the paper, and can supply paper of various thicknesses. An object is to provide an apparatus.

本発明の給紙装置は、用紙を積載するテーブルと、上記テーブルの中央部分の空間部に設けられた、用紙を吸引・搬送する手段と、積載された用紙の搬送方向側に設けられた、用紙の搬送を食い止めるストッパとを備え、上記テーブルの中央部分の空間部に吸引された用紙が上記ストッパの下をくぐって搬送される給紙装置であって、上記テーブルを用紙の幅方向で移動可能とすることにより、上記テーブルの中央部分の空間部の幅を調整可能としたことを特徴とする。 The sheet feeding device of the present invention is provided in a table for stacking sheets, a means for sucking / conveying sheets provided in a space portion in a central portion of the table, and provided in a conveying direction side of the stacked sheets. And a stopper for stopping the conveyance of the sheet, and a sheet feeding device in which the sheet sucked into the space in the central portion of the table is conveyed under the stopper, and the table is moved in the width direction of the sheet. By making it possible, the width of the space portion of the central portion of the table can be adjusted.

本発明の給紙装置によれば、用紙積載テーブルを移動させることができ、テーブルの中央部分の空間部の幅を調整可能であるので、用紙が変形し吸引されるのに必要なスペースを必要に応じて調整することが可能となる。例えば、用紙が薄く、柔らかい場合には、狭い幅でも吸引可能であるので、テーブルの中央部分の空間部の幅を狭くすることにより、2枚目以降の表紙が搬送されるのを防止することができ、一方、用紙が厚く、固い場合には、テーブルの中央部分の空間部の幅を広げることによって用紙を大きく変形させることができ、用紙を送り出すことができる。 According to the paper feeding device of the present invention, the paper stacking table can be moved and the width of the space portion at the center of the table can be adjusted, so that a space necessary for the paper to be deformed and sucked is required. It becomes possible to adjust according to. For example, if the paper is thin and soft, it can be sucked even with a narrow width. Therefore, by reducing the width of the space at the center of the table, it is possible to prevent the second and subsequent covers from being conveyed. On the other hand, when the paper is thick and hard, the paper can be greatly deformed by widening the width of the space at the center of the table , and the paper can be fed out.

以下、本発明に係る給紙装置を、用紙束と表紙を重ね合わせる重ね合わせ装置の表紙給紙装置として用いた実施例について説明する。
図1は用紙束と表紙を重ね合わせる重ね合わせ装置を示す図であり、1は表紙2を積載するテーブル、3は積載された表紙の搬送方向側に設けられた、表紙の搬送を食い止めるためのストッパ、4はテーブル1の中央部分の空間部に設けられた吸引部、5aは移動ベルト、5b、5cは移動ベルト駆動ローラである。吸引部4は移動ベルト5aに固着されており、移動ベルト駆動ローラ5b、5cによって移動ベルト5aが回転移動することにより、吸引部4に吸引された表紙2が一枚ずつ送り出される。これらのテーブル1、ストッパ3、吸引部4、移動ベルト5a、移動ベルト駆動ローラ5b、5cが本発明の給紙装置を構成している。
Hereinafter, an embodiment in which the paper feeding device according to the present invention is used as a cover paper feeding device of an overlaying device that superimposes a sheet bundle and a cover will be described.
FIG. 1 is a diagram showing a superimposing device that superimposes a stack of sheets and a cover. 1 is a table on which a cover 2 is stacked, and 3 is provided on the transport direction side of the stacked cover to stop the transport of the cover. The stopper 4 is a suction portion provided in the space of the central portion of the table 1, 5a is a moving belt, 5b and 5c are moving belt drive rollers. The suction unit 4 is fixed to the moving belt 5a. When the moving belt 5a is rotated by the moving belt driving rollers 5b and 5c, the cover 2 sucked by the suction unit 4 is sent out one by one. The table 1, the stopper 3, the suction part 4, the moving belt 5a, and the moving belt driving rollers 5b and 5c constitute the paper feeding device of the present invention.

図2は給紙装置の部分拡大図であり、図に示すように、ストッパ3の先端はテーブル1の表紙2の載置面より下方に位置しており、表紙の搬送を阻止できるようになっている。また、吸引部4はテーブル1の中央部分の空間部に設けられており、表紙2の一番下の表紙2aが吸引部4によって空気吸引により吸引された後、移動ベルト5aが駆動されることにより、吸引された表紙2aがストッパ3の下をくぐって搬送される。そして、テーブル1は図示矢印方向に手動または駆動モータにより移動させることができ、テーブル1の中央部の空間部の幅を表紙の厚さや固さに応じて調整することができる。 FIG. 2 is a partially enlarged view of the sheet feeding device. As shown in FIG. 2, the tip of the stopper 3 is positioned below the mounting surface of the cover 2 of the table 1 so that the conveyance of the cover can be prevented. ing. The suction unit 4 is provided in the space of the central portion of the table 1, and the moving belt 5a is driven after the bottom cover 2a of the cover 2 is sucked by the suction unit 4 by air suction. As a result, the sucked cover sheet 2a passes under the stopper 3 and is conveyed. The table 1 can be moved manually or by a drive motor in the direction of the arrow shown in the figure, and the width of the space at the center of the table 1 can be adjusted according to the thickness and hardness of the cover.

一方、図1の6aは搬送ベルト、6b、6cは搬送ベルト駆動ローラ、6d、6eは押えローラであり、これらの搬送ベルト6a、搬送ベルト駆動ローラ6b、6c、押えローラ6d、6eにより給紙装置から搬送されてくる表紙2が用紙束と表紙を重ね合わせる合流位置まで搬送される。また、7a、8aは搬送ベルト、7b、7c、8b、8cは搬送ベルト駆動ローラ、7d、7e、8d、8eは押えローラであり、これらの搬送ベルト7a、8a、搬送ベルト駆動ローラ7b、7c、8b、8c、押えローラ7d、7e、8d、8eにより丁合い装置等から搬送されてくる本身が、本身と表紙を重ね合わせる合流位置まで搬送される。   On the other hand, 6a in FIG. 1 is a conveyor belt, 6b and 6c are conveyor belt drive rollers, and 6d and 6e are press rollers. Paper is fed by these conveyor belts 6a, conveyor belt drive rollers 6b and 6c, and presser rollers 6d and 6e. The cover 2 conveyed from the apparatus is conveyed to a joining position where the sheet bundle and the cover are overlapped. Reference numerals 7a and 8a denote conveyance belts, 7b, 7c, 8b and 8c denote conveyance belt drive rollers, and 7d, 7e, 8d and 8e denote press rollers. These conveyance belts 7a and 8a and conveyance belt drive rollers 7b and 7c , 8b, 8c, and the pressing rollers 7d, 7e, 8d, 8e, the main body conveyed from the collating device or the like is conveyed to a joining position where the main body and the cover are overlapped.

そして、本身と表紙の重ね合わせ時には、図2に示すように、表紙2の一番下の表紙2aが吸引部4により吸引された後、移動ベルト5aが駆動されることにより、吸引された表紙2aがストッパ3の下をくぐって搬送され、図3に示すように、搬送ベルト6aにより本身と表紙を重ね合わせる合流位置10まで搬送される。一方、この表紙2の搬送と同期して、図3に示すように、丁合装置等からの本身9が搬送ベルト7a、8aによって搬送され、本身と表紙を重ね合わせる合流位置10で表紙2と重ね合わせられた後、次工程の製本装置等に搬送される。   When the main body and the cover are overlapped, as shown in FIG. 2, the lower cover 2a of the cover 2 is sucked by the suction portion 4, and then the moving belt 5a is driven to drive the sucked cover. 2a is transported under the stopper 3, and is transported to the joining position 10 where the body and the cover are overlapped by the transport belt 6a as shown in FIG. On the other hand, in synchronization with the transport of the cover 2, as shown in FIG. 3, the main body 9 from the collating device or the like is transported by the transport belts 7a and 8a, and the cover 2 After being overlaid, it is conveyed to a bookbinding apparatus or the like in the next process.

図2は表紙が薄い場合のテーブルの位置を示す図であり、この場合、表紙が薄く、柔らかいので、テーブル1の中央部分の空間部の幅が狭くても表紙の吸引が可能であり、吸引された表紙をストッパ3の下をくぐらせて搬送ベルト6aの方向に搬送することができるとともに、2枚目以降の表紙が搬送されるのを防止することができる。一方、表紙が厚い用紙の場合には、テーブル1の中央部分の空間部の幅が狭いと、吸引が足らず、表紙はストッパ3により止められてしまう。このような場合には、図4に示すように、手動またはモータ駆動によりテーブル1の中央部分の空間部の幅を拡げることにより、厚く固い用紙であっても、大きく変形させることができるので、吸引部4によって吸引することができ、吸引された表紙2aをストッパ3の下をくぐらせて搬送ベルト6aの方向に搬送することが可能となる。 FIG. 2 is a diagram showing the position of the table when the cover is thin. In this case, since the cover is thin and soft, the cover can be sucked even if the space of the central portion of the table 1 is narrow. The covered cover can pass under the stopper 3 and be conveyed in the direction of the conveying belt 6a, and the second and subsequent covers can be prevented from being conveyed. On the other hand, when the cover is thick, if the width of the space portion at the center of the table 1 is narrow, suction is insufficient and the cover is stopped by the stopper 3. In such a case, as shown in FIG. 4, even a thick and hard paper can be greatly deformed by expanding the width of the space portion of the central portion of the table 1 by manual or motor drive. The suction part 4 can be sucked, and the sucked cover 2a can be passed under the stopper 3 and transported in the direction of the transport belt 6a.

以上のように、用紙積載テーブルを可動としたことにより、テーブルの中央部分の空間部の幅を調整することができ、用紙が変形し吸引されるのに必要なスペースを必要に応じて調整することができるので、厚く、固い用紙であっても給紙を行うことができる。 As described above, by making the paper stacking table movable, the width of the space at the center of the table can be adjusted, and the space necessary for the deformation and suction of the paper is adjusted as necessary. Therefore, even thick and hard paper can be fed.

なお、上記の実施例では、本発明の給紙装置を表紙の給紙装置に適用した例について説明したが、本発明の給紙装置は、表紙以外の様々な用紙の給紙を行う場合にも使用することができる。   In the above-described embodiment, the example in which the paper feeding device of the present invention is applied to the cover paper feeding device has been described. However, the paper feeding device of the present invention is used when feeding various paper other than the cover. Can also be used.
