Description

本発明は、複数枚の用紙が重ね合わされた紙束を1枚ずつの用紙に分離しやすいように捌く紙捌き装置及び紙捌き方法に関する。   The present invention relates to a paper handling apparatus and a paper handling method for easily separating a paper bundle in which a plurality of papers are overlapped into one paper.

従来より、クレジットカードや携帯電話の利用明細書は、所定の用紙に利用明細情報が印字され、封筒に封入されて利用者に発送されているが、利用明細書を発送するクレジットカード会社や携帯電話会社のほとんどは、広告情報が掲載された印刷物を利用明細書とともに封筒に封入して利用者に発送している。   Conventionally, the usage statement information of a credit card or a mobile phone is printed on a predetermined sheet of usage statement information and enclosed in an envelope and sent to the user. Most telephone companies enclose printed materials with advertisement information in an envelope together with a usage statement and send them to users.

また、広告情報が掲載された印刷物が封筒に封入されてなるダイレクトメールやビジネスメールにおいても、複数の印刷物がダイレクトメールやビジネスメールの送付先に応じた組み合わせで封筒に同封され、発送されている。   Also, in direct mail and business mail in which printed materials with advertisement information are enclosed in envelopes, multiple printed materials are enclosed in envelopes and sent in combinations according to the destination of direct mail or business mail. .

このように複数の印刷物を1つの封筒に同封する場合は、まず、1つの封筒に同封する複数の印刷物を組み合わせる必要がある。従来より、複数の印刷物を組み合わせる場合は、組み合わされる複数の印刷物を、その種類毎に設けられたフィーダから1枚ずつフィードし、フィードされた印刷物を搬送する搬送経路上にて順次重ね合わせることが行われ、それにより、複数の印刷物が組み合わされている(例えば、特許文献1参照。)。そのため、印刷物を1枚ずつフィードするフィーダのそれぞれには、フィードされる印刷物がその種類毎に複数枚重ね合わされて供給されることになる。   Thus, when enclosing a plurality of printed materials in one envelope, it is necessary to combine a plurality of printed materials enclosed in one envelope first. Conventionally, when combining a plurality of printed materials, it is possible to feed the combined printed materials one by one from a feeder provided for each type, and sequentially superimpose them on a conveyance path for conveying the fed printed materials. This is done, and a plurality of printed materials are combined (for example, refer to Patent Document 1). Therefore, a plurality of printed materials to be fed are superimposed and supplied to each feeder that feeds printed materials one by one.

搬送経路上で組み合わされた複数の印刷物は、その後、1つの封筒に封入されることになる。

The plurality of printed materials combined on the conveyance path are then sealed in one envelope.

しかしながら、上述したように印刷物等の用紙が複数枚重ね合わされた場合、重ね合わされた用紙どうしが静電気等の作用によって密着してしまい、フィーダにかけられた際、一度に複数枚の用紙がフィードされてしまう、いわゆるダブルフィードが生じてしまう虞れがある。そこで、複数枚重ね合わされた用紙をフィーダにかける際に、複数枚の用紙が重ね合わされた紙束を作業員が手作業で波打たせるように揺動させることにより、1枚ずつの用紙に分離しやすいように捌くことが行われているが、この作業は人手による作業であるため、一度に捌くことができる用紙の枚数には限度があり、1つのフィーダにかけられる用紙の枚数や、用紙がかけられるフィーダの数が多い場合、作業効率が著しく低下してしまうという問題点がある。   However, as described above, when a plurality of sheets such as printed matter are overlapped, the overlapped sheets are brought into close contact with each other by the action of static electricity or the like, and a plurality of sheets are fed at once when applied to the feeder. In other words, so-called double feed may occur. Therefore, when a plurality of stacked sheets are loaded on the feeder, the sheet stack on which the plurality of sheets are stacked is swung so as to be manually waved to separate the sheets one by one. However, since this is a manual operation, there is a limit to the number of sheets that can be rolled at one time, and the number of sheets that can be applied to a single feeder is limited. When the number of feeders to be applied is large, there is a problem that work efficiency is remarkably lowered.

本発明は、上述したような従来の技術が有する問題点に鑑みてなされたものであって、重ね合わされた複数枚の用紙を人手によらずに分離しやすいように捌くことができる紙捌き装置及び紙捌き方法を提供することを目的とする。   The present invention has been made in view of the problems of the prior art as described above, and is a paper-making apparatus capable of separating a plurality of stacked sheets so as to be easily separated without manual intervention. And a paper-making method.

上記目的を達成するために本発明は、
重ね合わされた複数枚の用紙を分離しやすいように捌く紙捌き装置であって、
前記重ね合わされた複数枚の用紙を表裏から挟み込む一対の押さえ部材と、
前記一対の押さえ部材に挟み込まれた前記複数枚の用紙に対して、該複数枚の用紙の一端部側から前記押さえ部材によって挟み込まれた領域に空気を吹き付ける空気吹付手段とを有し、
前記一対の押さえ部材はそれぞれ、前記複数枚の用紙面に平行に、かつ、前記空気吹付手段からの空気の吹き付け方向に直交する方向に並んだ2つの平板部から構成され、該2つの平板部の当該2つの平板部が並ぶ方向外側の領域が前記複数枚の用紙に接し、当該2つの平板部が並ぶ方向内側の領域が前記複数枚の用紙との間に空隙を有するように前記複数枚の用紙の挟み込む面に対して傾斜して配置されている。
In order to achieve the above object, the present invention provides:
A paper making apparatus that easily separates a plurality of stacked sheets,
A pair of pressing members for sandwiching the plurality of superimposed sheets of paper from the front and back;
An air spraying means for blowing air to a region sandwiched by the pressing member from one end side of the plurality of sheets sandwiched between the pair of pressing members;
Each of the pair of pressing members is composed of two flat plate portions arranged in parallel to the surface of the plurality of sheets and in a direction orthogonal to the air blowing direction from the air blowing means. The plurality of sheets so that the outer region in the direction in which the two flat plate portions are aligned is in contact with the plurality of sheets, and the inner region in the direction in which the two flat plate portions are aligned has a gap between the plurality of sheets. The sheet is disposed to be inclined with respect to the sheet sandwiching surface.

上記のように構成された本発明においては、重ね合わされた複数枚の用紙が一対の押さえ部材によって表裏から挟み込まれた状態で、この複数枚の用紙に対して、複数枚の用紙の一端部側から押さえ部材によって挟み込まれた領域に空気吹付手段から空気が吹き付けられると、吹き付けられた空気が複数枚の用紙間を通って反対側に抜けて、複数枚の用紙が分離することになる。その際、一対の押さえ部材がそれぞれ、複数枚の用紙面に平行に、かつ、空気吹付手段からの空気の吹き付け方向に直交する方向に並んだ2つの平板部から構成され、この2つの平板部の2つの平板部が並ぶ方向外側の領域が複数枚の用紙に接し、2つの平板部が並ぶ方向内側の領域が複数枚の用紙との間に空隙を有するように複数枚の用紙の挟み込む面に対して傾斜して配置されているので、この押さえ部材によって複数枚の用紙に局所的に圧力が加わることがなく、それにより、複数枚の用紙間に過度の摩擦が生じず、また、空気吹付手段から複数枚の用紙に空気が吹き付けられた際、2つの平板部が並ぶ方向内側と複数枚の用紙との間の空隙にて複数枚の用紙が広がり、それにより、複数枚の用紙がその領域で大きく離れることになり、その後、複数枚の用紙がフィーダにかけられた際に分離しやすくなる。また、複数枚の用紙の中に折り曲げられた用紙が混入していた場合、その折り曲げ状態における開放側から空気が吹き付けられると、吹き付けられた空気が、その用紙の開放された側から入り込んで開放されていない側に突き当たり、それにより、折り曲げられた用紙が、吹き付けられた空気によって空気が吹き付けられる側とは反対側に飛び出す。これにより、折り曲げられた用紙を検出することもできる。   In the present invention configured as described above, in a state where a plurality of stacked sheets are sandwiched from the front and back by a pair of pressing members, one end side of the plurality of sheets with respect to the plurality of sheets When air is blown from the air blowing means to the area sandwiched by the pressing members, the blown air passes between the plurality of sheets and escapes to the opposite side, and the plurality of sheets are separated. At that time, each of the pair of pressing members is composed of two flat plate portions arranged in parallel to a plurality of paper surfaces and in a direction orthogonal to the air blowing direction from the air blowing means. The surface on which the plurality of sheets are sandwiched so that the outer area in the direction in which the two flat plate portions are aligned contacts a plurality of sheets, and the inner area in the direction in which the two flat plate portions are aligned has a gap between the plurality of sheets Therefore, the pressing member does not locally apply pressure to the plurality of sheets, thereby preventing excessive friction between the plurality of sheets and air. When air is blown onto the plurality of sheets from the spraying means, the plurality of sheets spreads in the gap between the inner side in the direction in which the two flat plate portions are aligned and the plurality of sheets. Will be far away in that area. Thereafter, a plurality of sheets is easily separated upon subjected to the feeder. In addition, when folded paper is mixed in a plurality of sheets, if air is blown from the open side in the folded state, the blown air enters from the opened side of the paper and is released. It strikes the side that is not, and thus the folded sheet jumps out to the side opposite to the side where the air is blown by the blown air. Thereby, the folded paper can also be detected.

以上説明したように本発明においては、重ね合わされた複数枚の用紙を表裏から挟み込む一対の押さえ部材と、一対の押さえ部材に挟み込まれた複数枚の用紙に対して、複数枚の用紙の一端部側から押さえ部材によって挟み込まれた領域に空気を吹き付ける空気吹付手段とを有し、一対の押さえ部材のそれぞれが、複数枚の用紙面に平行に、かつ、空気吹付手段からの空気の吹き付け方向に直交する方向に並んだ2つの平板部から構成され、この2つの平板部の2つの平板部が並ぶ方向外側の領域が複数枚の用紙に接し、2つの平板部が並ぶ方向内側の領域が複数枚の用紙との間に空隙を有するように複数枚の用紙の挟み込む面に対して傾斜して配置されている構成としたため、空気吹付手段から複数枚の用紙に空気が吹き付けられた際、吹き付けられた空気が複数枚の用紙間を通って反対側に抜けて、複数枚の用紙が分離することになるが、その際、2つの平板部が並ぶ方向内側と複数枚の用紙との間の空隙にて複数枚の用紙が広がり、それにより、複数枚の用紙がその領域で大きく離れることになり、重ね合わされた複数枚の用紙を人手によらずに分離しやすいように捌くことができる。   As described above, in the present invention, a pair of pressing members that sandwich a plurality of stacked sheets from the front and back, and one end portion of the plurality of sheets with respect to the plurality of sheets sandwiched between the pair of pressing members. Air blowing means for blowing air to the area sandwiched by the pressing member from the side, and each of the pair of pressing members is parallel to the plurality of sheets and in the direction of air blowing from the air blowing means. Consists of two flat plate portions arranged in an orthogonal direction, and an outer region in the direction in which the two flat plate portions of the two flat plate portions are in contact with a plurality of sheets, and a plurality of inner regions in the direction in which the two flat plate portions are arranged. Since the structure is arranged so as to be inclined with respect to the surface where the plurality of sheets are sandwiched so that there is a gap between the sheets, when the air is blown from the air blowing means to the plurality of sheets, The attached air passes between the multiple sheets and escapes to the opposite side, separating the multiple sheets. At that time, between the inner side in the direction in which the two flat plates are aligned and the multiple sheets A plurality of sheets spread in the gap of the plurality of sheets, so that the plurality of sheets are largely separated in the region, and the plurality of stacked sheets can be easily separated without human intervention. .

以下に、本発明の実施の形態について図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

The air supply unit 61 and the air supply nozzle 62 constituting air blowing means for blowing air to a plurality of sheets, and the end surface supporting members 20a and 20b of the mounting table 30 and the pressing members 10a and 10b are placed in a region surrounded by the air supply unit. When the placed paper is lifted by the air blown from the air supply nozzle 62 and jumps upward, the optical sensor 51 detects that fact and the fact that the paper has been lifted is optical. A patrol light 52 that lights when it is detected by the capacitors 51, and a control unit 53 for lighting Patlite 52 based on the detection result of the optical sensor 51.

端面支え部材20a,20bは、載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置された紙束を構成する複数枚の用紙の端面を支えるものであって、コの字型を有し、コの字型の1つの面が紙束の一方の表出面の一部に当接する当接面21a,21bとなる。また、当接面21a,21bに対向する面には、当接面21a,21bに当接した紙束を当接面21a,21bに対して弾性力によって押し付ける押し付け部材である押し付けばね22a,22bが取り付けられている。なお、押し付け部材としては、当接面21a,21bに当接した紙束を当接面21a,21bに対して弾性力によって押し付ける押し付けばね22a,22bではなく、空気圧やモータ等を利用することも考えられる。この端面支え部材20a,20bは、載置台30上に載置される用紙の大きさに合わせて互いの間隔を調節できるように移動自在に構成されている。   The end surface support members 20a and 20b support the end surfaces of a plurality of sheets constituting a sheet bundle placed in an area surrounded by the end surface support members 20a and 20b and the pressing members 10a and 10b of the mounting table 30. Thus, it has a U-shape, and one surface of the U-shape becomes contact surfaces 21a and 21b that contact a part of one exposed surface of the paper bundle. Further, pressing springs 22a and 22b, which are pressing members that press the paper bundle contacting the contact surfaces 21a and 21b against the contact surfaces 21a and 21b by an elastic force, are provided on the surfaces facing the contact surfaces 21a and 21b. Is attached. As the pressing member, air pressure, a motor, or the like may be used instead of the pressing springs 22a and 22b that press the paper bundle in contact with the contact surfaces 21a and 21b against the contact surfaces 21a and 21b by elastic force. Conceivable. The end surface support members 20a and 20b are configured to be movable so that the distance between them can be adjusted according to the size of the paper placed on the placement table 30.

押さえ部材10a,10bはそれぞれ、2つの端面支え部材20a,20bを結ぶ方向に並んだ2つの平板部11a,12a及び11b,12bから構成されている。この平板部11aと平板部12a、並びに平板部11bと平板部12bは、互いに連結しており、連結部分が2つの押さえ部材10a,10bが離れる方向に突出したV字形状となっている。このような平板部11a,12aの角度は、支持板15aに取り付けられた角度調節部14aによって調節され、また、平板部11b,12bの角度は、支持板15bに取り付けられた角度調節部14bによって調節されている。この角度調節部14a,14bを用いることにより、載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置された複数枚の用紙の種類等に応じて、平板部11a,12a及び11b,12bの角度を調節することができる。また、2つの押さえ部材10a,10bのうち一方の押さえ部材10aは、載置台30に取り付けられた調節用ハンドル13を回すことによって、押さえ部材10bとの間隔が調節可能となっている。   Each of the holding members 10a and 10b includes two flat plate portions 11a and 12a and 11b and 12b arranged in a direction connecting the two end surface support members 20a and 20b. The flat plate portion 11a and the flat plate portion 12a, and the flat plate portion 11b and the flat plate portion 12b are connected to each other, and the connecting portion has a V shape protruding in the direction in which the two pressing members 10a and 10b are separated. The angles of the flat plate portions 11a and 12a are adjusted by the angle adjusting portion 14a attached to the support plate 15a, and the angles of the flat plate portions 11b and 12b are adjusted by the angle adjusting portion 14b attached to the support plate 15b. It has been adjusted. By using the angle adjusting portions 14a and 14b, a flat plate is formed according to the types of the plurality of sheets placed in the region surrounded by the end surface support members 20a and 20b and the pressing members 10a and 10b. The angles of the parts 11a, 12a and 11b, 12b can be adjusted. In addition, one of the two pressing members 10a and 10b can adjust the interval between the pressing member 10b by turning the adjusting handle 13 attached to the mounting table 30.

載置台30には、2つの押さえ部材10a,10bが対向する領域に表裏貫通した穴部31が形成されており、この穴部31に対向する領域に、エアー供給器61から供給された空気を排出するエアー供給ノズル62が配置されている。それにより、エアー供給器61から供給された空気が載置台30の穴部31が形成された領域に対してエアー供給ノズル62によって吹き付けられることになる。そして、エアー供給ノズル62は、載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置された用紙の重ね合わせ方向に支持軸63によって穴部31に対向しながら移動可能に構成されている。すなわち、押さえ部材10a,10bをそれぞれ構成する2つの平板部11a,12a及び11b,12bは、エアー供給ノズル62からの空気の吹き付け方向に直交する方向に並んでいることになる。また、図2に示すように、エアー供給ノズル62はその先端部が複数のエアー吹出口64からなり、複数のエアー吹出口64は、載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置された用紙の重ね合わせ方向に直交する方向に配列されている。   The mounting table 30 is formed with a hole portion 31 penetrating front and back in a region where the two pressing members 10a and 10b are opposed to each other, and air supplied from the air supply device 61 is supplied to the region facing the hole portion 31. An air supply nozzle 62 for discharging is disposed. Thereby, the air supplied from the air supply device 61 is blown by the air supply nozzle 62 to the region where the hole 31 of the mounting table 30 is formed. The air supply nozzle 62 is opposed to the hole 31 by the support shaft 63 in the stacking direction of the paper placed in the area surrounded by the end surface support members 20a and 20b and the pressing members 10a and 10b of the placement table 30. It is configured to be movable. That is, the two flat plate portions 11a, 12a and 11b, 12b constituting the pressing members 10a, 10b are arranged in a direction orthogonal to the direction of blowing air from the air supply nozzle 62. As shown in FIG. 2, the air supply nozzle 62 has a plurality of air outlets 64 at its tip, and the plurality of air outlets 64 include the end surface support members 20 a and 20 b and the holding member 10 a of the mounting table 30. 10b are arranged in a direction perpendicular to the overlapping direction of the sheets placed in the area surrounded by 10b.

光学センサ51は、一対のセンサからなり、一方から照射された光が他方にて受光されているかどうかによって一対のセンサ間に物体が存在するかどうかを検出するものであって、載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に用紙が載置された状態ではセンサ間に用紙が存在せず、載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置された用紙がエアー供給ノズル62から吹き付けられる空気によって持ち上げられた場合にその用紙がセンサ間に存在するような位置に配置されている。   The optical sensor 51 includes a pair of sensors, and detects whether or not an object exists between the pair of sensors based on whether light emitted from one is received by the other. In a state where the sheet is placed in the region surrounded by the end surface support members 20a and 20b and the pressing members 10a and 10b, no sheet exists between the sensors, and the end surface support members 20a and 20b of the mounting table 30 and the pressing member 10a, When the paper placed in the area surrounded by 10b is lifted by the air blown from the air supply nozzle 62, the paper is arranged at a position between the sensors.

以下に、上記のように構成された紙捌き装置1を用いた紙捌き方法について説明する。   Hereinafter, a papermaking method using the papermaking apparatus 1 configured as described above will be described.

図3は、図1に示した紙捌き装置1の載置台30上に複数枚の印刷物40が載置された状態を示す図である。   FIG. 3 is a diagram showing a state in which a plurality of printed materials 40 are placed on the placement table 30 of the paper making apparatus 1 shown in FIG.

図3に示すように、図1に示した紙捌き装置1を用いて捌く複数枚の印刷物40からなる紙束は、その一端部が載置台30に当接するように、用紙向き検出装置1の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置される。この際、調節用ハンドル13を回すことにより、2枚の平板部11a,12aからなる押さえ部材10aを移動させ、紙捌き装置1の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置された複数枚の印刷物40からなる紙束を、一対の押さえ部材10a,10bによって表裏から挟み込むようにする。すなわち、押さえ部材10a,10bをそれぞれ構成する平板部11a,12a、並びに11b,12bは、印刷物40の面に平行に並べられていることになる。押さえ部材10a,10bは、互いに連結した平板部11aと平板部12a、並びに平板部11bと平板部12bが、連結部分が2つの押さえ部材10a,10bが離れる方向に突出したV字形状となっているため、平板部11a,11b,12a,12bは、印刷物40に当接する面に対して傾斜した状態となり、押さえ部材10a,10bの2つの端面支え部材20a,20bを結ぶ方向、すなわち、平板部11a,12a、並びに平板部11b,12bが並ぶ方向外側の領域が印刷物40にそれぞれ接し、平板部11a,12a、並びに平板部11b,12bが並ぶ方向内側の領域が印刷物40との間に空隙を有するようになる。また、押さえ部材10a,10bによって表裏から挟み込まれた複数枚の印刷物40からなる紙束は、紙束の表出面となる印刷物40の一部が端面支え部材20a,20bの当接面21a,21bに当接し、重ね合わされた複数枚の印刷物40からなる紙束が押し付けばね22a,22bによって当接面21a,21bに押し付けられる。この際、光学センサ51を構成する一対のセンサ間には印刷物40が存在していないため、光学センサ51においては印刷物40が検出されていない状態となっている。また、載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域には穴部31が形成されているため、この領域に載置された印刷物40はそれぞれの一部が穴部31から表出することになる。   As shown in FIG. 3, a paper bundle made up of a plurality of printed products 40 that are rolled using the paper handling device 1 shown in FIG. 1 is arranged so that one end of the paper bundle 40 comes into contact with the mounting table 30. It is placed in a region surrounded by the end face support members 20a, 20b and the pressing members 10a, 10b. At this time, by rotating the adjustment handle 13, the pressing member 10a composed of the two flat plate portions 11a and 12a is moved and surrounded by the end surface supporting members 20a and 20b and the pressing members 10a and 10b of the paper making apparatus 1. A paper bundle composed of a plurality of printed materials 40 placed in the region is sandwiched from the front and back by a pair of pressing members 10a and 10b. That is, the flat plate portions 11a, 12a and 11b, 12b constituting the pressing members 10a, 10b, respectively, are arranged in parallel to the surface of the printed matter 40. The pressing members 10a and 10b have a V-shape in which the flat plate portion 11a and the flat plate portion 12a connected to each other, and the flat plate portion 11b and the flat plate portion 12b protrude in a direction in which the two pressing members 10a and 10b are separated from each other. Therefore, the flat plate portions 11a, 11b, 12a, and 12b are inclined with respect to the surface that contacts the printed matter 40, and the direction connecting the two end surface support members 20a and 20b of the pressing members 10a and 10b, that is, the flat plate portion. 11a, 12a and the areas outside in the direction in which the flat plate portions 11b, 12b are arranged are in contact with the printed matter 40, respectively, and the regions inside the direction in which the flat plate portions 11a, 12a and the flat plate portions 11b, 12b are arranged have a gap between them. To have. Further, in a paper bundle composed of a plurality of printed materials 40 sandwiched between the front and back by the pressing members 10a and 10b, a part of the printed material 40 that becomes the exposed surface of the paper bundle is a contact surface 21a and 21b of the end surface support members 20a and 20b. A paper bundle made up of a plurality of printed products 40 that are in contact with each other is pressed against the contact surfaces 21a and 21b by the pressing springs 22a and 22b. At this time, since the printed matter 40 does not exist between the pair of sensors constituting the optical sensor 51, the printed matter 40 is not detected in the optical sensor 51. Moreover, since the hole part 31 is formed in the area | region enclosed by the end surface support members 20a and 20b and the pressing members 10a and 10b of the mounting base 30, the printed matter 40 mounted in this area is partly each. It will be exposed from the hole 31.

次に、上述したように紙捌き装置1の載置台30上に載置された複数枚の印刷物40からなる紙束を捌く際の動作について説明する。   Next, an operation when a paper bundle made up of a plurality of printed materials 40 placed on the placement table 30 of the paper handling apparatus 1 as described above will be described.

図4は、図1に示した紙捌き装置1にて載置台30上に載置された紙束を捌く際の動作を説明するための図であり、端面支え部材20a側から見た図である。   FIG. 4 is a view for explaining the operation when the paper bundle placed on the placing table 30 is spread by the paper making apparatus 1 shown in FIG. 1, and is a view seen from the end face supporting member 20a side. is there.

図4に示すように、複数枚の印刷物40が重ね合わされた紙束を、その印刷物70の一端部がそれぞれ載置台30に当接するように載置台30上に載置し、上述したように一対の押さえ部材10a,10bによって表裏から挟み込み、空気吹付部であるエアー供給器61及びエアー供給ノズル62を駆動させると、エアー供給器61からエアー供給ノズル62に空気が送られてエアー供給ノズル62のエアー吹出口64から空気が排出されるとともに、エアー供給ノズル62が押さえ部材10b側から押さえ部材10a側に支持軸63に沿って移動しはじめる。   As shown in FIG. 4, a paper bundle in which a plurality of printed materials 40 are overlaid is placed on the mounting table 30 such that one end of the printed material 70 is in contact with the mounting table 30. When the air supply unit 61 and the air supply nozzle 62, which are air blowing parts, are driven by the pressing members 10a and 10b, the air is supplied from the air supply unit 61 to the air supply nozzle 62, and the air supply nozzle 62 Air is discharged from the air outlet 64, and the air supply nozzle 62 starts to move along the support shaft 63 from the pressing member 10b side to the pressing member 10a side.

エアー供給ノズル62は、載置台30の穴部31に対向する領域に配置されているため、エアー供給器61から供給された空気は、エアー供給ノズル62によって、載置台30の穴部31から表出した印刷物40の端部側から吹き付けられる。また、エアー供給ノズル62は、初期状態として、押さえ部材10b側に配置されており、また、エアー供給ノズル62を構成する複数のエアー吹出口64が、載置台30上に載置された印刷物40の重ね合わせ方向に直交する方向に配列されているため、エアー供給ノズル62から排出された空気は、載置台30上に載置された印刷物40のうち、まず、押さえ部材10bに接している印刷物40に吹き付けられ、その後、エアー供給ノズル62の移動に伴って、その他の印刷物に1枚ずつ順次吹き付けられていくことになる。これにより、載置台30上に載置される印刷物40の載置台30と接する辺を第1の辺部とすると、押さえ部材10a,10bをそれぞれ構成する2枚の平板部11a,12a、並びに11b,12bは、第1の辺部と平行に並んでおり、この第1の辺部側からエアー供給ノズル62によって印刷物40に空気が吹き付けられることになる。   Since the air supply nozzle 62 is disposed in a region facing the hole portion 31 of the mounting table 30, the air supplied from the air supply device 61 is exposed from the hole portion 31 of the mounting table 30 by the air supply nozzle 62. It is sprayed from the end side of the printed matter 40 that has been taken out. In addition, the air supply nozzle 62 is disposed on the holding member 10 b side as an initial state, and a plurality of air outlets 64 constituting the air supply nozzle 62 are printed on the mounting table 30. Since the air discharged from the air supply nozzle 62 is arranged in a direction orthogonal to the overlapping direction of the printed matter 40, the printed matter 40 that is in contact with the pressing member 10b among the printed matter 40 placed on the placement table 30 is firstly printed. 40, and then, as the air supply nozzle 62 moves, the other printed matter is sequentially blown one by one. Accordingly, when the side of the printed material 40 placed on the placement table 30 that contacts the placement table 30 is the first side, the two flat plate portions 11a, 12a, and 11b that respectively constitute the pressing members 10a and 10b. , 12b are arranged in parallel with the first side, and air is blown onto the printed matter 40 by the air supply nozzle 62 from the first side.

エアー供給ノズル62から排出された空気が、載置台30上に載置された印刷物40に吹き付けられると、図4に示すように、エアー供給ノズル62によって吹き付けられた空気が印刷物40の表裏、すなわち、載置台30上に載置された複数枚の印刷物40の間を通って載置台30とは反対側に抜け、それにより、載置台30上に載置された複数枚の印刷物40がエアー供給ノズル62から吹き付けられた空気によって一旦分離する。   When the air discharged from the air supply nozzle 62 is blown onto the printed product 40 placed on the mounting table 30, the air blown by the air supply nozzle 62, as shown in FIG. Then, the plurality of printed materials 40 placed on the mounting table 30 pass between the plurality of printed materials 40 to the opposite side of the mounting table 30, whereby the plurality of printed materials 40 placed on the mounting table 30 are supplied with air. Once separated by the air blown from the nozzle 62.

そして、エアー供給ノズル62が支持軸63によって印刷物40の重ね合わせ方向に移動することにより、載置台30上に載置された複数枚の印刷物40のそれぞれに対して、エアー供給ノズル62から空気が順次吹き付けられていき、それにより、載置台30上に載置された複数枚の印刷物40の全てがエアー供給ノズル62から吹き付けられた空気によって一旦分離し、載置台30上に載置された紙束が捌かれることになる。   The air supply nozzle 62 moves in the overlapping direction of the printed matter 40 by the support shaft 63, so that air is supplied from the air supply nozzle 62 to each of the plurality of printed items 40 placed on the placement table 30. Paper that is sequentially blown, whereby all of the plurality of printed products 40 placed on the placement table 30 are once separated by the air blown from the air supply nozzle 62, and the paper placed on the placement table 30 A bunch will be sown.

なお、上述したような複数枚の印刷物40が重ね合わされた紙束を載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置して、複数枚の印刷物40が重ね合わされた紙束を押さえ部材10a,10bによって表裏から挟み込み、押さえ部材10a,10bに挟み込まれた印刷物40に対して穴部31を介してエアー供給ノズル62から空気を吹き付ける処理を、制御部(不図示)による制御によって自動化して行うことも考えられる。その場合、複数枚の印刷物40が重ね合わされた紙束が載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に載置されたことが検知されると、押さえ部材10aが押さえ部材10bに向かう方向に移動して押さえ部材10a,10bによって複数枚の印刷物40が重ね合わされた紙束を表裏から挟み込み、その後、押さえ部材10a,10bによって紙束が表裏から挟み込まれた旨が検知されると、上述したようにエアー供給器61及びエアー供給ノズル62が駆動し、エアー供給器61からエアー供給ノズル62に空気が送られてエアー供給ノズル62のエアー吹出口64から空気が排出され、印刷物40に対して空気が吹き付けられる構成とすることが考えられる。   Note that a plurality of printed materials 40 are placed by placing a paper bundle on which a plurality of printed materials 40 as described above are superimposed on a region surrounded by the end surface support members 20a and 20b and the pressing members 10a and 10b of the mounting table 30. The control unit performs a process of sandwiching a stack of paper sheets from the front and back by the pressing members 10a and 10b and blowing air from the air supply nozzle 62 to the printed matter 40 sandwiched between the pressing members 10a and 10b through the hole 31. It is also conceivable to perform this automatically by control (not shown). In that case, when it is detected that the sheet bundle in which the plurality of printed materials 40 are stacked is placed in the region surrounded by the end surface support members 20a and 20b and the holding members 10a and 10b of the mounting table 30, the holding member 10a moves in a direction toward the pressing member 10b, and a paper bundle in which a plurality of printed materials 40 are overlapped by the pressing members 10a and 10b is sandwiched from the front and back, and then the paper bundle is sandwiched from the front and back by the pressing members 10a and 10b. When the effect is detected, the air supply device 61 and the air supply nozzle 62 are driven as described above, and air is sent from the air supply device 61 to the air supply nozzle 62 and air is supplied from the air outlet 64 of the air supply nozzle 62. It is conceivable that air is blown to the printed matter 40.

ここで、押さえ部材10a,10bの形状によって生じる作用について説明する。   Here, an operation caused by the shape of the pressing members 10a and 10b will be described.

図5は、図1に示した紙捌き装置1の押さえ部材10a,10bの形状によって生じる作用を説明するための図である。   FIG. 5 is a view for explaining the action caused by the shape of the pressing members 10a and 10b of the paper making apparatus 1 shown in FIG.

上述したように、押さえ部材10a,10bが、互いに連結した平板部11aと平板部12a、並びに平板部11bと平板部12bが、連結部分が2つの押さえ部材10a,10bが離れる方向に突出したV字形状となっているため、載置台30の端面支え部材20a,20bと押さえ部材10a,10bによって囲まれた領域に複数枚の印刷物40が重ね合わされた紙束が載置されると、平板部11a,12a、並びに平板部11b,12bが並ぶ方向外側の領域が印刷物40の紙束にそれぞれ接し、平板部11a,12a、並びに平板部11b,12bが並ぶ方向内側の領域が印刷物40の紙束との間に空隙を有するようになる。   As described above, the pressing members 10a and 10b are connected to each other by the flat plate portion 11a and the flat plate portion 12a, and the flat plate portion 11b and the flat plate portion 12b are V portions whose connecting portions protrude in the direction in which the two pressing members 10a and 10b are separated. When the paper bundle in which a plurality of printed materials 40 are stacked is placed in the region surrounded by the end surface support members 20a and 20b and the pressing members 10a and 10b of the mounting table 30 because of the letter shape, the flat plate portion 11a, 12a and the area outside in the direction in which the flat plate portions 11b, 12b are arranged are in contact with the paper bundle of the printed matter 40, and the area inside the direction in which the flat plate portions 11a, 12a and the flat plate portions 11b, 12b are arranged is the paper bundle of the printed matter 40 There will be a gap between them.

そして、載置台30に形成された穴部31は、2つの押さえ部材10a,10bが対向する領域に形成されているため、エアー供給ノズル62のエアー吹出口64から排出された空気は、印刷物40の2つの押さえ部材10a,10bによって挟み込まれた領域に吹き付けられることになる。   And since the hole part 31 formed in the mounting base 30 is formed in the area | region where the two pressing members 10a and 10b oppose, the air discharged | emitted from the air blower outlet 64 of the air supply nozzle 62 is printed matter 40. The two pressing members 10a and 10b are sprayed onto the region sandwiched between the two pressing members 10a and 10b.

すると、図5に示すように、紙束を構成する印刷物40のうち、2つの押さえ部材10a,10bによって挟み込まれた領域が、印刷物40と押さえ部材10a,10bとの間の空隙にて押さえ部材10a,10bに沿うように広がり、エアー供給ノズル62から空気が吹き付けられている印刷物40とそれに面して重ね合わされた印刷物40とが互いに離れ、それにより、複数枚の印刷物40がその領域で大きく離れることになり、その後、複数枚の印刷物40が重ね合わされた紙束がフィーダにかけられた際に1枚ずつの印刷物40に分離しやすくなる。   Then, as shown in FIG. 5, the area sandwiched by the two pressing members 10 a and 10 b in the printed material 40 constituting the paper bundle is a pressing member in the gap between the printed material 40 and the pressing members 10 a and 10 b. 10a and 10b, and the printed material 40 that is blown with air from the air supply nozzle 62 is separated from the printed material 40 that is overlapped with the printed material 40, so that a plurality of printed materials 40 are enlarged in that region. After that, when a paper bundle in which a plurality of printed materials 40 are overlapped is put on the feeder, the printed materials 40 are easily separated into individual printed materials 40.

また、上述した処理によって印刷物40が捌かれる際、複数枚の印刷物40が等間隔に一旦分離するため、エアー供給ノズル62から空気を吹き付ける処理と同時に、光センサ等を用いて印刷物40の枚数をカウントすることもできる。また、捌かれた紙束は、重ね合わされた複数枚の印刷物40が等間隔となって重ね合わされた状態となるため、その後、カウンタ等を用いて枚数をカウントすることもできる。   Further, when the printed matter 40 is spread by the above-described processing, the plurality of printed matter 40 is once separated at equal intervals. Therefore, simultaneously with the process of blowing air from the air supply nozzle 62, the number of printed matter 40 is determined using an optical sensor or the like. You can also count. Further, since the stacked paper bundle is in a state in which a plurality of the printed products 40 are overlapped at equal intervals, the number of sheets can be counted using a counter or the like thereafter.

なお、上述した実施の形態においては、1枚のシートからなる印刷物40を載置台30上に載置し、エアー供給ノズル62から吹き付ける空気によって印刷物40を1枚ずつ分離しやすくする例を示したが、複数枚の紙片が綴じられたり折り畳まれたりして構成された冊子等を本発明の用紙として載置台30上に載置し、エアー供給ノズル62から吹き付ける空気によって冊子を1冊ずつ分離しやすくすることも考えられる。   In the above-described embodiment, an example in which the printed matter 40 made of one sheet is placed on the placement table 30 and the printed matter 40 is easily separated one by one by the air blown from the air supply nozzle 62 is shown. However, a booklet configured by binding or folding a plurality of paper pieces is placed on the placement table 30 as the paper of the present invention, and the booklets are separated one by one by the air blown from the air supply nozzle 62. It is possible to make it easier.

ここで、上述した紙捌き装置1においては、重ね合わされた複数枚の印刷物40の中に、複数枚の印刷物40を重ね合わせる際に折り曲げられた印刷物が混入していた場合、その印刷物を検出することもできる。以下に、その動作について説明する。   Here, in the papermaking apparatus 1 described above, when a printed product that is folded when a plurality of printed products 40 are overlapped with each other, the printed product 40 is detected. You can also. The operation will be described below.

図6は、図1に示した紙捌き装置1において、重ね合わされた複数枚の印刷物40の中に折り曲げられた印刷物が混入していた場合にその印刷物を検出する動作を説明するための図であり、(a)は印刷物の重ね合わせ状態を示す図、(b)は(a)に示したように重ね合わされた印刷物40の中から折り曲げられた印刷物41が検出される状態を示す図である。   FIG. 6 is a diagram for explaining an operation of detecting the printed material when the folded printed material is mixed in the multiple printed materials 40 in the papermaking apparatus 1 shown in FIG. (A) is a diagram showing a superimposed state of printed materials, and (b) is a diagram showing a state in which a folded printed material 41 is detected from the superimposed printed materials 40 as shown in (a). .

複数の印刷物40が重ね合わされる際、重ね合わされるもののうち1枚の印刷物41が図6(a)に示すように折り曲げられた状態で重ね合わされたものとする。   When a plurality of printed materials 40 are overlaid, it is assumed that one of the printed materials 41 is overlaid in a folded state as shown in FIG.

このように折り曲げられた印刷物41を含む複数の印刷物40が、印刷物41の折り曲げ状態における開放側が載置台30側となるように載置台30上に載置され、その状態でエアー供給ノズル62から空気が吹き付けられると、折り曲げられていない印刷物40においては、上述したようにエアー供給ノズル62から吹き付けられた空気がその表裏を通って載置台30とは反対側に抜けるため、載置台30から持ち上げられることはないが、折り曲げられた印刷物41においては、図6(b)に示すように、エアー供給ノズル62から吹き付けられた空気が開放された側から内部に入り込んで開放されていない側に突き当たり、それにより、載置台30上から持ち上げられて空気が吹き付けられる側とは反対側に飛び出す。エアー供給ノズル62から吹き付けられた空気によって持ち上げられた印刷物41は、重ね合わされた印刷物40が一対の押さえ部材10a,10bによって挟み込まれているため、エアー供給ノズル62から印刷物40に空気が吹き付けられなくなった後も、載置台30に接するような元の状態に戻ることはないが、重ね合わされた印刷物40が押し付けばね22a,22bによって端面支え部材20a,20bの当接面21a,21bに押し付けられることによって、エアー供給ノズル62から吹き付けられた空気によって持ち上げられた印刷物41が、エアー供給ノズル62から空気が吹き付けられなくなった後に、載置台30に接するような元の状態に戻ってしまう可能性をさらに低減することができる。   A plurality of printed materials 40 including the printed material 41 folded in this manner are placed on the mounting table 30 such that the open side of the printed material 41 in the folded state is the mounting table 30 side, and air is supplied from the air supply nozzle 62 in that state. Is blown up, the printed material 40 that is not bent is lifted from the mounting table 30 because the air blown from the air supply nozzle 62 passes through the front and back sides to the opposite side of the mounting table 30 as described above. However, in the folded printed matter 41, as shown in FIG. 6B, the air blown from the air supply nozzle 62 enters the inside from the opened side and hits the unopened side, Thereby, it is lifted from the mounting table 30 and jumps out to the side opposite to the side where air is blown. The printed matter 41 lifted by the air blown from the air supply nozzle 62 is not blown from the air supply nozzle 62 to the printed matter 40 because the superimposed printed matter 40 is sandwiched between the pair of pressing members 10a and 10b. After that, the original state that comes into contact with the mounting table 30 is not restored, but the superimposed printed material 40 is pressed against the contact surfaces 21a and 21b of the end surface support members 20a and 20b by the pressing springs 22a and 22b. Therefore, there is a possibility that the printed matter 41 lifted by the air blown from the air supply nozzle 62 may return to the original state where it comes into contact with the mounting table 30 after the air is no longer blown from the air supply nozzle 62. Can be reduced.

このようにしてエアー供給ノズル62から吹き付けられた空気によって印刷物41が持ち上げられると、光学センサ51を構成する一対のセンサのうち一方から照射された光が印刷物41によって遮られ、他方のセンサにて受光されなくなる。   When the printed matter 41 is lifted by the air blown from the air supply nozzle 62 in this way, the light emitted from one of the pair of sensors constituting the optical sensor 51 is blocked by the printed matter 41, and the other sensor No light is received.

すると、その旨が制御器53に通知され、制御器53の制御によってパトライト52が点灯し、載置台30上に載置された印刷物40の中に、折り曲げられて重ね合わされた印刷物が存在する旨が示され、載置台30から持ち上げられた印刷物41が印刷物40の中から一旦抜き取られる。   Then, the fact is notified to the controller 53, the patrol light 52 is turned on by the control of the controller 53, and the printed material 40 placed on the mounting table 30 includes a printed material that is folded and superimposed. The printed matter 41 lifted from the mounting table 30 is once extracted from the printed matter 40.

なお、重ね合わされた複数枚の印刷物40の中に折り曲げられた印刷物41が混入していた場合、上述したようにエアー供給ノズル62から吹き付けられる空気によってその印刷物を検出するためには、検出される印刷物が大きく折り曲げられている必要があるが、上述した処理によって捌かれた紙束は、重ね合わされた複数枚の印刷物40が等間隔となって重ね合わされた状態となっているため、大きく折り曲げられていないものであっても、目視にてその印刷物を検出しやすくなる。   In addition, when the folded printed matter 41 is mixed in a plurality of the printed matter 40 that is overlapped, it is detected in order to detect the printed matter by the air blown from the air supply nozzle 62 as described above. Although the printed material needs to be largely folded, the paper bundle that has been rolled up by the above-described processing is in a state of being largely folded because a plurality of superimposed printed materials 40 are overlaid at equal intervals. Even if it is not, the printed matter can be easily detected visually.

なお、本形態においては、複数枚の用紙が重ね合わされた紙束を挟み込む一対の押さえ部材10a,10bが、2枚の平板部11a,12a、並びに11b,12bが互いに連結してV字型となったものを例に挙げて説明したが、重ね合わされた用紙が載置台30上に載置された場合に、エアー供給ノズル62からの空気の吹き付け方向に直交する方向に並んだ2つの平板部から構成され、この2つの平板部が並ぶ方向外側の領域が用紙に接し、2つの平板部が並ぶ方向内側の領域が用紙との間に空隙を有するように複数の用紙の挟み込む面に対して傾斜して配置されるものでれば、丸みを有するものや、2枚の平板部が連結せず、ハの字型のもの等であってもよい。ただし、2枚の平板部が互いに連結したものの方が、エアー供給ノズル62から排出された空気が一対の押さえ部材の外側に漏れることがなく、それにより、重ね合わされた複数枚の用紙を離れやすくすることができる。   In this embodiment, a pair of pressing members 10a and 10b sandwiching a bundle of sheets on which a plurality of sheets are overlapped, the two flat plate portions 11a and 12a, and 11b and 12b are connected to each other to form a V shape. As an example, the two flat plate portions arranged in a direction orthogonal to the direction of blowing air from the air supply nozzle 62 when the stacked paper is placed on the placement table 30 have been described. The surface on which a plurality of sheets are sandwiched so that the area on the outside in the direction in which the two flat plate portions are arranged is in contact with the paper, and the area on the inside in the direction in which the two flat plate portions are arranged has a gap between the two sheets As long as it is inclined and arranged, it may be round, or the two flat plate portions may not be connected, and may have a square shape. However, in the case where the two flat plate portions are connected to each other, the air discharged from the air supply nozzle 62 does not leak to the outside of the pair of pressing members, thereby easily separating a plurality of stacked sheets. can do.

また、押さえ部材10a,10bの上端部を互いに離れる方向に広げることにより、重ね合わされた複数枚の用紙を、載置台30の押さえ部材10a,10bと端面支え部材20a,20bとで囲まれる領域に載置しやすくすることも考えられる。   Further, by expanding the upper end portions of the pressing members 10a and 10b in the direction away from each other, a plurality of overlapped sheets are placed in a region surrounded by the pressing members 10a and 10b and the end surface support members 20a and 20b of the mounting table 30. It is also possible to make it easier to place.

また、本形態においては、エアー供給ノズル62が、図2に示したように、載置台30上に載置された印刷物の重ね合わせ方向に直交する方向に配列された複数のエアー吹出口64を先端部に有するものであるが、載置台30上に載置された印刷物の重ね合わせ方向に直交する方向を長手方向とする長手形状の吹出口を1つだけ有するものであってもよく、また、その形状が長手形状でないものであってもよい。ただし、載置台30上に載置された印刷物の重ね合わせ方向に直交する方向に複数のエアー吹出口64が配列されたものや、載置台30上に載置された印刷物の重ね合わせ方向に直交する方向を長手方向とする長手形状の吹出口を1つだけ有するものである場合は、載置台30上に載置された印刷物と平行に印刷物の1枚ずつにスポット的に多くの空気を順次吹き付けることができるため、エアー供給ノズル62から吹き付けられた空気によって印刷物を持ち上がりやすくすることができる。   Further, in this embodiment, as shown in FIG. 2, the air supply nozzle 62 includes a plurality of air outlets 64 arranged in a direction orthogonal to the overlapping direction of the printed material placed on the placement table 30. Although it has in a front-end | tip part, it may have only one longitudinally shaped blower outlet which makes the direction orthogonal to the superimposition direction of the printed matter mounted on the mounting base 30 a longitudinal direction, The shape may not be a longitudinal shape. However, a plurality of air outlets 64 are arranged in a direction orthogonal to the overlapping direction of the printed material placed on the mounting table 30 or a direction orthogonal to the overlapping direction of the printed material placed on the mounting table 30. In the case where there is only one longitudinal outlet having the longitudinal direction as the direction to be printed, a large amount of air is sequentially spotted on each printed matter in parallel with the printed matter placed on the placing table 30. Since it can be sprayed, the printed matter can be easily lifted by the air blown from the air supply nozzle 62.

また、本形態においては、載置台30上に載置された印刷物に対して載置台30の穴部31を介して空気を吹き付けるエアー供給ノズル62が、支持軸63によって印刷物の重ね合わせ方向に穴部31に対向しながら移動する構成としているが、エアー供給ノズル62を固定するとともに載置台30を印刷物の重ね合わせ方向に移動させることによりエアー供給ノズル62と載置台30との相対位置を変化させ、エアー供給ノズル62から排出された空気が吹き付けられる印刷物を変えていく構成とすることも考えられる。また、エアー供給ノズル62と載置台30とを固定し、エアー供給ノズル62を載置台30の穴部31の全体に対して一度に空気を吹き付ける構成とすることも考えられる。   Further, in the present embodiment, the air supply nozzle 62 that blows air through the hole portion 31 of the mounting table 30 to the printed material placed on the mounting table 30 has a hole in the overlapping direction of the printed material by the support shaft 63. The air supply nozzle 62 is fixed and the mounting table 30 is moved in the overlapping direction of the printed matter to change the relative position between the air supply nozzle 62 and the mounting table 30.
