Description

本発明は、郵便物などの紙葉類束から紙葉類を一通ずつ分離して下流の処理部に供給する紙葉類分離機構及び紙葉類分離方法に関し、さらには、このような紙葉類分離機構を備える紙葉類供給装置に関する。   The present invention relates to a paper sheet separating mechanism and a paper sheet separating method for separating paper sheets one by one from a bundle of paper sheets such as postal items and supplying them to a downstream processing unit, and further to such a paper sheet. The present invention relates to a paper sheet supply device including a paper separation mechanism.

郵便物などの紙葉類束から紙葉類を一通ずつ分離して下流の処理部に供給する紙葉類分離機構が知られている。例えば、図１８に示す紙葉類供給装置は、紙葉類束１０を立位で載置する載置台１０１と、載置された紙葉類束１０を下流に向けて搬送する搬送コンベア１０２と、搬送コンベア１０２の終端部まで搬送された紙葉類束１０から紙葉類１１を一通ずつ分離して下流の処理部に供給する紙葉類分離機構１０３とを備えて構成されている。   2. Description of the Related Art There is known a paper sheet separation mechanism that separates paper sheets one by one from a bundle of paper sheets such as mail and supplies them to a downstream processing unit. For example, the paper sheet supply apparatus shown in FIG. 18 includes a mounting table 101 on which the paper sheet bundle 10 is placed in a standing position, and a transport conveyor 102 that transports the placed paper sheet bundle 10 toward the downstream. And a paper sheet separating mechanism 103 that separates the paper sheets 11 one by one from the paper sheet bundle 10 transported to the terminal end of the transport conveyor 102 and supplies them to the downstream processing unit.

このような紙葉類供給装置において、載置台１０１に立位で載置された紙葉類束１０は、搬送コンベア１０２に設けられるコンパートメント１０４により姿勢を維持したまま、コンパートメント１０４及び底面ベルト１０５によって紙葉類分離機構１０３に向けて搬送される。紙葉類分離機構１０３に到着した紙葉類束１０は、先頭の紙葉類１１から順に、吸着ベルト１０６を介して真空吸着室１０７に吸着され、吸着ベルト１０６の周回運動により所定の搬送方向（矢印方向）に一通ずつ供給される。   In such a paper sheet supply apparatus, the paper sheet bundle 10 placed in a standing position on the mounting table 101 is maintained by the compartment 104 provided on the transport conveyor 102 and is maintained by the compartment 104 and the bottom belt 105. It is conveyed toward the paper sheet separating mechanism 103. The paper sheet bundle 10 that has arrived at the paper sheet separating mechanism 103 is adsorbed to the vacuum adsorbing chamber 107 via the adsorbing belt 106 in order from the leading paper sheet 11, and is moved in a predetermined transport direction by the circumferential movement of the adsorbing belt 106. It is supplied one by one (in the direction of the arrow).

しかしながら、上記のように構成される吸着ベルト方式の紙葉類分離機構１０３では、密着力が強い紙葉類束１０から一通の紙葉類１１を分離する場合、一通だけを上手く分離することができずに、二通以上を同時に供給してしまうことがあった。例えば、表面がビニールコーティングされた紙葉類同士を重ねた場合、紙葉類同士が強い密着力で結合されてしまうため、吸着ベルト１０６による吸着・搬送作用では分離されず、複数枚が重なった状態で供給されてしまうという問題があった。   However, in the suction belt type paper sheet separating mechanism 103 configured as described above, when separating one paper sheet 11 from the paper sheet bundle 10 having strong adhesion, only one paper can be separated well. In some cases, two or more messages were supplied simultaneously. For example, when paper sheets with vinyl coatings on top of each other are stacked, the paper sheets are bonded with a strong adhesion, so that they are not separated by the adsorption / conveying action by the adsorption belt 106, and a plurality of sheets overlap. There was a problem of being supplied in the state.

そこで、可動式の吸着ヘッド（吸盤）を用いて、紙葉類の端部を紙葉類束から引き剥がす吸着・引き剥がし手段（捕捉手段）と、端部が引き剥がされた紙葉類を紙葉類束から分離する分離手段（剥離手段）と、紙葉類束から分離された紙葉類を下流の処理部に向けて搬送する搬送手段とを備える紙葉類分離機構が提案されている（例えば、特許文献１参照）。このような紙葉類分離機構によれば、紙葉類の端部を部分的に吸着し、紙葉類束から引き剥がすことができるので、吸着ベルト式の紙葉類分離機構に比べて、優れた分離性能を発揮することが可能である。
特開昭６３−１０６２４５号公報 Therefore, using a movable suction head (suction cup), the suction / peeling means (capturing means) for peeling off the edge of the paper sheet from the bundle of paper sheets, and the paper sheet with the edge peeled off. There has been proposed a paper sheet separating mechanism that includes a separating means (separating means) for separating from a paper sheet bundle and a conveying means for conveying the paper sheet separated from the paper sheet bundle toward a downstream processing unit. (For example, refer to Patent Document 1). According to such a paper sheet separation mechanism, the edge of the paper sheet can be partially adsorbed and peeled off from the paper sheet bundle, so compared to the adsorption belt type paper sheet separation mechanism, Excellent separation performance can be exhibited.
JP 63-106245 A

しかしながら、特許文献１に記載される紙葉類分離機構の吸着ヘッドは、紙葉類の面に対して垂直方向に直線運動するに過ぎないため、端部同士が強い力で密着している紙葉類束の場合、紙葉類の引き剥がしに失敗する可能性があった。   However, since the suction head of the paper sheet separation mechanism described in Patent Document 1 merely moves linearly in a direction perpendicular to the surface of the paper sheet, the paper whose edges are in close contact with each other with a strong force In the case of leaf bundles, there was a possibility that peeling of paper sheets could fail.

本発明は、上記の事情にかんがみなされたものであり、密着力の強い紙葉類束から紙葉類を確実に一通ずつ分離し、安定的に供給することができる紙葉類分離機構、紙葉類分離方法及び紙葉類供給装置の提供を目的とする。   The present invention has been considered in view of the above circumstances, a paper sheet separating mechanism that can reliably separate paper sheets one by one from a paper sheet bundle having strong adhesion and can be stably supplied, paper An object is to provide a leaf separation method and a paper sheet supply apparatus.

That is, the suction head provided in the paper sheet separating mechanism of the present invention peels off the end of the sucked paper sheet from the paper sheet bundle by twisting motion, so that the linear motion in the direction perpendicular to the surface of the paper sheet Compared to conventional suction heads that only peel off, excellent peeling performance can be exhibited.

また、本発明の紙葉類分離機構は、前記分離手段が、回転自在な分離ローラを備え、当該分離ローラを、前記吸着・引き剥がし手段によって部分的に引き剥がされた紙葉類と紙葉類束との間の隙間に入り込ませることにより、紙葉類を紙葉類束から分離する構成としてある。

The paper sheets are separated from the paper sheet bundle by entering the gap between the paper bundles.
If it does in this way, the paper sheet partially peeled off by the adsorption | suction and peeling means can be isolate | separated quickly and reliably from a paper sheet bundle.

また、本発明の紙葉類分離機構は、前記搬送手段が、前記分離ローラとの間で紙葉類を挟む搬送ローラを備え、当該搬送ローラの回転駆動により、紙葉類束から分離された紙葉類を前記処理部に向けて搬送する構成としてある。

また、本発明の紙葉類分離方法は、紙葉類束から紙葉類を一通ずつ分離して下流の処理部に供給する紙葉類分離方法であって、紙葉類の端部を吸着して紙葉類束から引き剥がす吸着・引き剥がし工程と、端部が引き剥がされた紙葉類を紙葉類束から分離する分離工程と、紙葉類束から分離された紙葉類を前記処理部に向けて搬送する搬送工程とを含み、前記吸着・引き剥がし工程が、紙葉類の端部を吸着し、かつ、吸着した紙葉類の端部をひねることにより行われる方法としてある。
このようにすると、密着力の強い紙葉類束から紙葉類を確実に一通ずつ分離し、安定的に供給することができる。 The paper sheet separation method of the present invention is a paper sheet separation method for separating paper sheets from a bundle of paper sheets one by one and supplying them to a downstream processing unit, and adsorbs the edge of the paper sheets. Then, an adsorption / peeling process for peeling off the paper sheet bundle, a separation process for separating the paper sheet whose edge has been peeled off from the paper sheet bundle, and a paper sheet separated from the paper sheet bundle As a method in which the adsorption / peeling step is performed by adsorbing an end portion of the paper sheet and twisting the end portion of the adsorbed paper sheet. is there.
If it does in this way, paper sheets can be reliably separated one by one from a paper sheet bundle with strong adhesion, and can be supplied stably.

また、本発明の紙葉類分離方法は、前記分離工程が、回転自在な分離ローラを、端部が引き剥がされた紙葉類と紙葉類束との間の隙間に入り込ませることにより行われる方法としてある。
このようにすると、部分的に引き剥がされた紙葉類を、紙葉類束から迅速かつ確実に分離させることができる。 In the paper sheet separation method of the present invention, the separation step is performed by causing a rotatable separation roller to enter a gap between the paper sheet from which the end is peeled off and the paper sheet bundle. There is as a method to be called.
In this way, the partially peeled paper sheet can be quickly and reliably separated from the paper sheet bundle.

また、本発明の紙葉類分離方法は、前記搬送工程が、前記分離ローラとの間で紙葉類を挟む搬送ローラの回転駆動により行われる方法としてある。
このようにすると、分離された紙葉類を確実に搬送できるだけでなく、分離ローラを搬送手段の一部に兼用し、搬送手段の構造を簡略化することができる。 Further, the paper sheet separating method of the present invention is a method in which the transporting process is performed by rotationally driving a transport roller that sandwiches the paper sheet with the separation roller.

以下、本発明の実施形態について、図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 3 is a plan view showing a paper sheet transport mechanism (standing position maintaining transport state) of the paper sheet supply apparatus according to the embodiment of the present invention, and FIG. 4 is a paper sheet supply apparatus according to the embodiment of the present invention. FIG. 5 is a plan view showing the paper sheet transport mechanism (posture control transport state) of the paper sheet supply apparatus according to the embodiment of the present invention. FIG. 6 is a front view showing a paper sheet transport mechanism (attitude control transport state) of the paper sheet supply apparatus according to the embodiment of the present invention.

これらの図に示すように、紙葉類搬送機構２０は、立位状態で紙葉類束１０が設置される載置台２１と、紙葉類束１０の姿勢を支えつつ搬送の付加力を与えるエンドプレート２２と、立位状態を維持しながら紙葉類束１０を搬送する立位維持搬送手段２３と、立位維持搬送手段２３の終端部まで搬送された紙葉類束１０を紙葉類分離機構３０に向けて搬送しつつ、紙葉類束１０の姿勢を制御する姿勢制御搬送手段２４とを備えている。   As shown in these drawings, the paper sheet transport mechanism 20 provides an additional force for transport while supporting the posture of the paper sheet bundle 10 and the mounting table 21 on which the paper sheet bundle 10 is placed in a standing position. The end plate 22, a standing maintenance transport unit 23 that transports the sheet bundle 10 while maintaining the standing state, and the sheet bundle 10 transported to the end portion of the standing maintenance transport unit 23 An attitude control conveying means 24 that controls the attitude of the sheet bundle 10 while conveying toward the separation mechanism 30 is provided.

立位維持搬送手段２３は、紙葉類１１の下端部と係合する爪付きの搬送ベルト２５を備えている。
搬送ベルト２５は、載置台２１に沿って二本並設されており、エンドプレート２２とほぼ同速で駆動することにより、紙葉類束１０が立位状態を維持したまま下流の姿勢制御搬送手段２４に向けて搬送される。 The standing position maintaining conveyance unit 23 includes a conveyance belt 25 with a claw that engages with a lower end portion of the paper sheet 11.
Two conveyor belts 25 are arranged side by side along the mounting table 21, and are driven at substantially the same speed as the end plate 22, so that the sheet bundle 10 is maintained in the standing state and the downstream attitude control conveyance is performed. It is conveyed toward the means 24.

姿勢制御搬送手段２４は、紙葉類１１の下端部と係合する爪付きの搬送ベルト２６と、紙葉類１１の姿勢を検知する角度検知センサ２７とを備えている。
搬送ベルト２６は、搬送ベルト２５から紙葉類１１を引き継ぐように二本並設されている。
角度検知センサ２７は、姿勢制御搬送手段２４の搬送経路に配置され、紙葉類１１の角度検知を行う。例えば、姿勢制御における紙葉類１１の目標角度が３０°である場合、正面から見て紙葉類１１の搬送方向に対して３０°で交わる直線上に三つの角度検知センサ２７を配置し、これらの角度検知センサ２７の検知タイミングにもとづいて紙葉類１１の角度検知を行う。 The attitude control conveyance means 24 includes a conveyance belt 26 with claws that engages with the lower end of the paper sheet 11, and an angle detection sensor 27 that detects the attitude of the paper sheet 11.
Two conveyance belts 26 are arranged side by side so as to take over the paper sheet 11 from the conveyance belt 25.
The angle detection sensor 27 is disposed in the conveyance path of the attitude control conveyance unit 24 and detects the angle of the paper sheet 11. For example, when the target angle of the paper sheet 11 in the posture control is 30 °, the three angle detection sensors 27 are arranged on a straight line that intersects at 30 ° with respect to the conveyance direction of the paper sheet 11 when viewed from the front. Based on the detection timing of these angle detection sensors 27, the angle of the paper sheet 11 is detected.

上記のように構成された紙葉類搬送機構２０において、図３及び図４に示すように、載置台２１（搬送ベルト２５）に紙葉類束１０を立位状態で載置すると、載置された紙葉類束１０は、エンドプレート２２及び搬送ベルト２５の搬送駆動により、立位状態を維持したまま下流に向けて搬送される。
図５及び図６に示すように、紙葉類束１０は、搬送ベルト２５から搬送ベルト２６に順次引き継がれる。搬送ベルト２６は、搬送ベルト２５（エンドプレート２２）よりも高速で搬送駆動するので、紙葉類束１０は、角度を変化させながら下流に向けて搬送される。その際、角度検知センサ２７によって紙葉類束１０の角度を検知し、搬送ベルト２５の駆動速度をフィードバック制御することによって、紙葉類束１０の角度を任意の値に調整することが可能になる。例えば、本実施形態では、搬送ベルト２６の終端部における紙葉類束１０の目標角度を３０°として、搬送ベルト２５の駆動速度をフィードバック制御する。 In the paper sheet transport mechanism 20 configured as described above, as shown in FIGS. 3 and 4, when the paper sheet bundle 10 is placed in a standing position on the placing table 21 (conveyor belt 25), the paper sheet is placed. The sheet bundle 10 thus conveyed is conveyed downstream while maintaining the standing state by the conveyance drive of the end plate 22 and the conveyance belt 25.
As shown in FIGS. 5 and 6, the sheet bundle 10 is successively transferred from the conveyance belt 25 to the conveyance belt 26. Since the transport belt 26 is transported and driven at a higher speed than the transport belt 25 (end plate 22), the sheet bundle 10 is transported downstream while changing the angle. At that time, the angle of the sheet bundle 10 can be adjusted to an arbitrary value by detecting the angle of the sheet bundle 10 by the angle detection sensor 27 and feedback controlling the driving speed of the conveying belt 25. Become. For example, in the present embodiment, the target angle of the sheet bundle 10 at the end portion of the conveyance belt 26 is set to 30 °, and the drive speed of the conveyance belt 25 is feedback-controlled.

Yes.

吸着・引き剥がし手段３１は、真空源に接続され、紙葉類１１の端部を吸着する吸着ヘッド３４と、吸着ヘッド３４を所定方向に移動させるアーム３５とを備えている。ここで、アーム３５は、吸着ヘッド３４を紙葉類１１の面に対して垂直方向に移動させるだけでなく、紙葉類１１の面に対して吸着ヘッド３４の吸着面を傾ける方向、すなわち吸着した紙葉類１１の端部をひねる方向に吸着ヘッド３４を移動させる。例えば、図７の（ｂ）に示す矢印方向に吸着ヘッド３４を移動させるように、アーム３５が駆動される。   The suction / peeling means 31 includes a suction head 34 that is connected to a vacuum source and sucks the end of the paper sheet 11 and an arm 35 that moves the suction head 34 in a predetermined direction. Here, the arm 35 not only moves the suction head 34 in a direction perpendicular to the surface of the paper sheet 11, but also tilts the suction surface of the suction head 34 with respect to the surface of the paper sheet 11, that is, suction. The suction head 34 is moved in a direction in which the end of the paper sheet 11 is twisted. For example, the arm 35 is driven so as to move the suction head 34 in the arrow direction shown in FIG.

分離手段３２は、回転自在な分離ローラ３６を備え、この分離ローラ３６を、吸着・引き剥がし手段３１によって部分的に引き剥がされた紙葉類１１と紙葉類束１０との間の隙間に入り込ませることにより、紙葉類１１を紙葉類束１０から完全に分離させる。
本実施形態では、回転駆動するプーリ３７に、三本の分離ローラ３６ａ〜３６ｃを放射状に突設している。各分離ローラ３６ａ〜３６ｃは、プーリ３７の回転方向に所定の間隔を存して並列し、所定のプーリ３７の回転に伴って公転するだけでなく、ローラ軸を中心とする自転も許容されている。そして、吸着ヘッド３４で部分的に引き剥がされた紙葉類１１と紙葉類束１０との間の隙間に、これらの分離ローラ３６ａ〜３６ｃを順次入り込ませることにより、紙葉類１１が紙葉類束１０から完全に分離される。

搬送手段３３は、分離ローラ３６ｃとの間で紙葉類１１を挟む搬送ローラ３９を備え、当該搬送ローラ３９の回転駆動により、紙葉類束１０から分離された紙葉類１１を下流の処理部に向けて搬送するように構成されている。
なお、上記の紙葉類分離機構３０では、分離ローラ３６の公転面の角度や吸着ヘッド３４の運動方向を調整することにより、様々な角度姿勢（水平姿勢や垂直姿勢を含む）の紙葉類束に対応可能である。また、紙葉類搬送機構２０における紙葉類の角度検知に応じて、分離ローラ３６の公転面の角度や吸着ヘッド３４の運動方向を自動的に調整するようにしてもよく、このようにすると、紙葉類分離機構３０の分離性能をより高めることができる。 The transport unit 33 includes a transport roller 39 that sandwiches the paper sheet 11 with the separation roller 36c, and the paper sheet 11 separated from the paper sheet bundle 10 by downstream driving of the transport roller 39 is processed downstream. It is comprised so that it may convey toward a part.
In the paper sheet separating mechanism 30 described above, the paper sheets of various angular postures (including a horizontal posture and a vertical posture) are adjusted by adjusting the angle of the revolution surface of the separation roller 36 and the moving direction of the suction head 34. Can handle bundles. Further, the angle of the revolution surface of the separation roller 36 and the direction of movement of the suction head 34 may be automatically adjusted according to the detection of the angle of the paper sheet in the paper sheet transport mechanism 20.

When the rearmost separation roller 36c reaches the position facing the conveying roller 39, the rotation drive of the pulley 37 is temporarily stopped. (Separation process)
Next, as shown in FIG. 10, the suction of the paper sheet 11 by the suction head 34 is released, and the transport roller 39 is driven to rotate. As a result, the paper sheet 11 sandwiched between the transport roller 39 and the separation roller 36c is transported toward the downstream processing unit. At this time, the conveyance guide 38 prevents the paper sheet 11 from sagging. (Conveying process)
When the conveyance of the paper sheet 11 is completed, as shown in FIG. 11, the pulley 37 is driven to rotate again, and the separation rollers 36a to 36c are returned to the original position. (Home return process)
