Description

本発明は、丁合機、詳しくは給紙棚に積み重ねた用紙のガイドに関するものである。 The present invention relates to a collating machine, and more particularly to a guide for sheets stacked on a sheet feeding shelf.

縦方向に多段の給紙棚を配置し、各給紙棚に積み重ねた用紙を１枚ごと所定の順に積み重ねて搬出してなる丁合機はよく知られている。このような丁合機では、各給紙棚に積み重ねた用紙を確実に給紙するために、各給紙棚に積み重ねた用紙の自由な移動を抑制するガイド板が設けられる。 2. Description of the Related Art A collating machine in which multistage sheet feeding shelves are arranged in the vertical direction and the sheets stacked on each sheet feeding shelf are stacked one by one in a predetermined order and carried out is well known. In such a collating machine, a guide plate that suppresses free movement of the sheets stacked on each sheet feeding shelf is provided in order to reliably feed the sheets stacked on each sheet feeding shelf.

図４は一つの給紙棚の給紙機構を示すもので、（ａ）は給紙棚に多数の用紙を積み重ねた丁合初期状態を示す側面図、（ｂ）は丁合が進み給紙棚の用紙の枚数が少数となった状態を示す側面図である。この図４において、１は用紙の残量に応じて昇降する給紙棚、２はガイド板、３は捌きエアを噴出すノズル、４は給紙ローラ、５は送りローラ、６は搬送ベルト、Ｐは用紙である。丁合時には、ノズル６から噴出すエアで１枚に捌かれた給紙棚上の用紙Ｐは給紙ローラ４で吸着して送りローラ５に送られ、搬送ベルト６上に他の給紙棚から搬出された用紙の上に積み重ねる。この積み重ねを多段の各給紙棚で行われて一冊分丁合いされる。 4A and 4B show a sheet feeding mechanism of one sheet feeding shelf. FIG. 4A is a side view showing an initial collating state in which a large number of sheets are stacked on the sheet feeding shelf, and FIG. It is a side view which shows the state in which the number of sheets of the shelf became a small number. In FIG. 4, 1 is a paper feed shelf that moves up and down according to the remaining amount of paper, 2 is a guide plate, 3 is a nozzle that blows air, 4 is a paper feed roller, 5 is a feed roller, 6 is a conveyor belt, P is paper. At the time of collation, the paper P on the paper feed shelf that has been rolled up by the air ejected from the nozzle 6 is attracted by the paper feed roller 4 and sent to the feed roller 5, and another paper feed shelf is placed on the transport belt 6. Stack on the paper unloaded from. This stacking is performed at each of the multistage paper feed shelves and collated for one book.

給紙棚１に多数の用紙Ｐを積み重ねて載置したとき、積み重ねた用紙Ｐの給紙側と反対側の端部に当接して、個別に用意した用紙Ｐの上下方向の移動をガイドするガイド板２を配置する。ガイド板２はその上端には給紙側に向けて折れ曲がる折曲片２ａが形成されており、この折曲片２ａにより捌きエアの吹き付けで用紙Ｐがめくれ上がって移動し、給紙ローラ４から外れてしまうことを防止するものである。 When a large number of sheets P are stacked and placed on the sheet feeding shelf 1, they contact the end of the stacked sheets P opposite to the sheet feeding side to guide the vertical movement of the individually prepared sheets P. A guide plate 2 is arranged. The guide plate 2 is formed with a bent piece 2a that is bent toward the paper feed side at the upper end thereof, and the paper P is turned up and moved by blowing air by the bent piece 2a. This prevents it from coming off.

このようなガイド板２の給紙棚１から折曲片２ａまでの高さは、給紙棚１に積み重ねる用紙束の厚みの最大値以上とされている。そのために、給紙棚１に積み重ねる用紙Ｐの枚数を多くし、ガイド板２の高さを高くすると、丁合が進み給紙棚１の用紙の枚数が少数になるにしたがい給紙棚１が上昇し、図４（ｂ）に示すように捌きエアの吹き付けで最上部の用紙Ｐがめくれ上がってその端部が折曲片２ａに当接するまで大きく移動し、給紙ミスを発生するという問題がある。また、このようなガイド板２は個別に作成されているので紛失しやすく、さらには給紙棚１に用紙を載置する度に、多段の給紙棚１のそれぞれに個別に配置しなければならないという面倒な問題があった。 The height of the guide plate 2 from the sheet feeding shelf 1 to the bent piece 2a is set to be equal to or greater than the maximum value of the thickness of the sheet bundle stacked on the sheet feeding shelf 1. For this reason, when the number of sheets P stacked on the sheet feeding shelf 1 is increased and the height of the guide plate 2 is increased, the sheet feeding shelf 1 is changed as the collation progresses and the number of sheets in the sheet feeding shelf 1 decreases. As shown in FIG. 4 (b), the uppermost sheet P is turned up by blowing air and moves greatly until the end of the sheet P comes into contact with the bent piece 2a. There is. Further, since such guide plates 2 are created individually, they are easily lost, and each time a sheet is placed on the paper feed shelf 1, it must be individually arranged on each of the multistage paper feed shelves 1. There was a troublesome problem of not becoming.

本発明が解決しようとする課題は、多段の給紙棚を有する丁合機において、各給紙棚へのガイドの配置が簡単であるとともに、給紙棚に積み重ねる用紙束の厚みにかかわらず給紙ミスを発生しにくいガイドを備えた丁合機を提供し、斯かる問題を解消する点である。 The problem to be solved by the present invention is that, in a collating machine having multi-stage paper feed shelves, the guides are easily arranged on the paper feed shelves, and the paper feed is performed regardless of the thickness of the stack of paper stacked on the paper feed shelves. The present invention is to provide a collating machine provided with a guide that is less likely to cause a paper error, and to solve such a problem.

本発明は、多段の給紙棚を有し、各給紙棚から供給された１枚ごとの用紙を所定の順に積み重ねて搬出してなる丁合機において、前記多段の給紙棚を複数段に分割し、分割した複数段の給紙棚にまたがり各給紙棚に積み重ねた用紙の端縁に当接する移動自在のガイド軸を、分割した複数段ごとに設置するとともに、前記各ガイド軸に各給紙棚に積み重ねた用紙のめくれ上がりを防止する部材を固定してなることを特徴とする。 The present invention provides a collating machine having a multi-stage paper feed shelf and stacking and feeding out the sheets supplied from each paper feed shelf in a predetermined order. A movable guide shaft that abuts against the edge of the paper stacked on each paper feed shelf across the plurality of divided paper feed shelves is installed for each of the divided multiple stages, and A member for preventing the sheets stacked on each sheet feeding shelf from being turned up is fixed .

本発明によれば、ガイド軸を移動して給紙棚から退避させた状態で給紙棚に積み重ねた用紙を載置し、載置後ガイド軸を移動して積み重ねた用紙の端縁に当接する。この当接は一度に複数段の給紙棚について同時に行うことができ、給紙棚へのガイドの配置が簡単となる。また、ガイド軸は丁合機に設置しているので、紛失することがなく、さらに、給紙する所定のレベルに固定して用紙のめくれ上がりを防止する部材を設けているので、給紙棚に積み重ねる用紙Ｐの枚数にかかわらず常に用紙のめくれ上がり移動による給紙ミスを確実に防止することができ、給紙棚に載置する用紙の枚数を大幅に増加することができる。 According to the present invention, the sheets stacked on the sheet feeding shelf are placed in a state where the guide shaft is moved and retracted from the sheet feeding shelf, and after the loading, the guide shaft is moved so as to contact the edge of the stacked sheets. Touch. This abutment can be performed simultaneously for a plurality of stages of paper feed shelves at a time, and the arrangement of the guides on the paper feed shelves is simplified. Further, since the guide shaft is installed in collator, without lost, further, since the set only a member for preventing upward and fixed to a predetermined level curling of the paper to be fed, the paper feed Regardless of the number of sheets P stacked on the shelf, it is possible to reliably prevent a sheet feeding error due to the sheet turning up and moving, and to greatly increase the number of sheets placed on the sheet feeding shelf.

多段の給紙棚を有する丁合機において、各給紙棚へのガイドの配置が簡単であるとともに、給紙棚に積み重ねる用紙束の厚みにかかわらず給紙ミスを発生しにくいガイドを備えた丁合機を提供する目的を、丁合機の機枠に回動自在に固定したアームに連結したガイド軸を、複数段の給紙棚にまたがって設置することにより達成した。 In the collating machine having multi-stage paper shelves, the guides are easily arranged on each paper feed shelf, and the guides are less likely to cause paper feed errors regardless of the thickness of the stack of paper stacked on the paper feed shelves. The purpose of providing a collating machine was achieved by installing a guide shaft connected to an arm that was rotatably fixed to the machine frame of the collating machine across multiple stages of paper feeding shelves.

図１および図２は実施例に係る丁合機の構成を示す斜視図、図３は図１に示す丁合機における給紙棚の給紙機構の動作を示す説明図で（ａ）は給紙棚に多数の用紙を積み重ねた丁合初期状態を示す側面図、（ｂ）は丁合が進み給紙棚の用紙の枚数が少数となった状態を示す側面図である。 1 and 2 are perspective views showing the configuration of the collating machine according to the embodiment. FIG. 3 is an explanatory view showing the operation of the paper feeding mechanism of the paper feeding shelf in the collating machine shown in FIG. FIG. 4B is a side view showing an initial collating state in which a large number of sheets are stacked on a paper shelf, and FIG. 5B is a side view showing a state in which collation has progressed and the number of sheets in the paper feeding shelf has become a small number.

本実施例に係る丁合機Ａは、図１に示すように給紙棚１１を縦方向に６段配列して構成され、各給紙棚１１の給紙機構自体は図４に示す従来の給紙機構と同様である。図１における１２は、各給紙棚１１の側部に沿って位置する機枠であり、この機枠１２の端面１２ａに、３段分の給紙棚１１に対応する間隔を隔てて取付金具１３が固着され、この取付金具１３に３段分の給紙棚１１に対応する２本の支点軸１４がそれぞれ回転自在に取付けられている。 As shown in FIG. 1, the collating machine A according to this embodiment is configured by arranging six stages of sheet feeding shelves 11 in the vertical direction, and the sheet feeding mechanism itself of each sheet feeding shelf 11 is the conventional one shown in FIG. This is the same as the paper feed mechanism. In FIG. 1, reference numeral 12 denotes a machine frame positioned along the side of each paper feed shelf 11, and mounting brackets are provided on the end surface 12 a of the machine frame 12 at intervals corresponding to the paper feed shelves 11 for three stages. 13 is fixed, and two fulcrum shafts 14 corresponding to the three-stage paper feed shelves 11 are rotatably attached to the mounting bracket 13.

各１本の支点軸１４の取付金具１３に位置する一方の端部に電磁ブレーキ１７がそれぞれ設置され、また支点軸１４の両端にはそれぞれアーム１５が固定され、このアーム１５の先端に、両端のアーム１５間に伸びるガイド軸１６が固定されている。すなわち、ガイド軸１６は３段分の給紙棚１１ごとにまたがって伸び、電磁ブレーキ１５が開放されている場合にはそれぞれ支点軸１４を支点として３段分の給紙棚１１に接近、離間する方向に自在に回動する。 An electromagnetic brake 17 is installed at one end portion of the mounting bracket 13 of each one fulcrum shaft 14, and an arm 15 is fixed to each end of the fulcrum shaft 14. A guide shaft 16 extending between the arms 15 is fixed. In other words, the guide shaft 16 extends over the three stages of the paper feed shelves 11, and when the electromagnetic brake 15 is opened, the guide shaft 16 approaches and separates from the three stages of the paper feed shelves 11 with the fulcrum shaft 14 as a fulcrum. Rotate freely in the direction of

各給紙棚１１には、ガイド軸１６が移動する切欠き１１ａが形成され、この切欠き１１ａの寸法は給紙棚１１に載置する最小寸法の用紙の端部の中央部に位置する寸法とされている。ガイド軸１６には、各給紙棚１１が給紙する位置と対応する所定のレベルに用紙のめくれ上がりを防止する部材、この実施例ではリング１８が固定されている。 Each paper feed shelf 11 is formed with a notch 11a through which the guide shaft 16 moves. The size of the notch 11a is a dimension located at the center of the end of the smallest size paper placed on the paper feed shelf 11. It is said that. On the guide shaft 16, a member for preventing the sheet from turning up to a predetermined level corresponding to the position where each sheet feeding shelf 11 feeds paper, in this embodiment, a ring 18 is fixed.

このように構成した丁合機Ａで丁合を行う場合、図１に示すようにガイド軸１６を回動して給紙棚１１から退避させ、各給紙棚１１に丁合する用紙を積み重ねて載置する。そのあとガイド軸１６を回動して図２に示すように積み重ねた用紙Ｐの端部に当接し、丁合機Ａを駆動する。電磁ブレーキ１７は丁合機Ａの駆動と連動するようにされており、丁合機Ａの駆動によって電磁ブレーキ１７が動作しガイド軸１６の移動を禁止する。 When collating is performed with the collating machine A configured as described above, as shown in FIG. 1, the guide shaft 16 is rotated to be retracted from the paper feed shelf 11, and sheets to be collated are stacked on each paper feed shelf 11. To place. Thereafter, the guide shaft 16 is rotated to come into contact with the end portion of the stacked sheets P as shown in FIG. The electromagnetic brake 17 is interlocked with the driving of the collating machine A, and the electromagnetic brake 17 is operated by the driving of the collating machine A to prohibit the movement of the guide shaft 16.

この禁止により図３（ａ）に示すように、ガイド軸１６は積み重ねた用紙Ｐの端部に当接した状態を維持し、ガイド軸１６に固定しためくれ上がりを防止するリング１８は給紙棚１１に積み重ねた最上部の用紙Ｐの近傍上方に位置し、これにより給紙を確実に行うことができる。 As a result of this prohibition, as shown in FIG. 3A, the guide shaft 16 is kept in contact with the end portion of the stacked sheets P, and the ring 18 that is fixed to the guide shaft 16 and prevents fold-up is provided in the sheet feeding shelf. 11 is located above the uppermost paper P stacked on the paper 11, so that paper can be reliably fed.

丁合が進められると給紙棚１１に積み重ねた用紙Ｐの枚数は減少し、その減少に応じて給紙棚１１は上昇する。このときめくれ上がりを防止するリング１８はガイド軸１６に固定されているので、図３（ｂ）に示すように減少した枚数の最上部の用紙Ｐの近傍上方に位置し、これにより給紙棚１１に積み重ねた用紙Ｐの枚数が減少しても給紙を確実に行うことができる。 As collation proceeds, the number of sheets P stacked on the paper feed shelf 11 decreases, and the paper feed shelf 11 rises in accordance with the decrease. At this time, the ring 18 that prevents turning-up is fixed to the guide shaft 16, so that it is positioned in the vicinity of the uppermost sheet P of the reduced number of sheets as shown in FIG. Thus, even if the number of sheets P stacked on the sheet 11 decreases, the sheet can be reliably fed.

以上の実施例に係る丁合機Ａでは、給紙棚１１を縦方向に６段配列して構成し、給紙棚１１を３段ごとに分割して各３段ごとの給紙棚１１にまたがってガイド軸１６を設けているが、給紙棚の段数は任意であり、また、分割する段数も任意である。また、ガイド軸１６の移動を電動機などで制御するようにしてもよい。 In the collating machine A according to the above embodiment, the paper feed shelves 11 are arranged in six stages in the vertical direction, and the paper feed shelves 11 are divided into three stages to form the paper feed shelves 11 for each three stages. The guide shaft 16 is provided across the sheet, but the number of stages of the paper feed shelves is arbitrary, and the number of stages to be divided is also arbitrary. Further, the movement of the guide shaft 16 may be controlled by an electric motor or the like.
