Description
本発明は、紙幣や伝票類の紙葉類が集積されている紙葉類収納部から紙葉類を分離する紙葉類分離機構および紙葉類分離集積機構に関する。 The present invention relates to a paper sheet separating mechanism and a paper sheet separating and accumulating mechanism for separating paper sheets from a paper sheet storage unit in which paper sheets of bills and slips are accumulated.
従来の紙葉類分離機構は、紙葉類を繰出すときにステージを上方向に移動させることによって集積されている紙葉類をピッカローラに押し付けると共に、ピッカローラを回転させて紙葉類を１枚ずつ分離してフィードローラと分離ローラとの間に繰出している（例えば、特許文献１参照。）。
しかしながら、上述した従来の技術においては、紙葉類を繰出すときピッカローラで紙葉類を押圧しているため、集積されている紙葉類間でピッカローラが押圧している箇所に比較的大きな摩擦が生じて、１番目に繰出す紙葉類と２番目に繰出す紙葉類との間に生じる摩擦と、２番目に繰出す紙葉類と３番目に繰出す紙葉類との間に生じる摩擦とのバランスによって、繰出される１番目の紙葉類につられるように２番目の紙葉類が動いてその姿勢がずれてしまう場合があり、特に２番目の紙葉類の一方の側が繰出方向に動いてしまい、他方の側が動かなかった場合、紙葉類の姿勢が大きくずれた状態となり、このような紙葉類を繰出してしまうと紙葉類搬送路の途中でジャム等の障害を起こす原因になるという問題がある。 However, in the above-described conventional technology, when picking up paper sheets, the paper sheets are pressed by the picker roller. Therefore, the picker rollers are relatively pressed between the stacked paper sheets. A large amount of friction occurs between the first and second paper sheets, and the second and third paper sheets. Due to the balance with the friction generated between them, the second paper sheet may move as if it is pulled by the first paper sheet to be fed out, and the posture may be shifted. If one side moves in the feeding direction and the other side does not move, the posture of the paper sheet is greatly shifted, and if such a paper sheet is fed out, it will jam in the middle of the paper sheet transport path. There is a problem of causing a failure such as.
この問題が起きる場合の紙葉類間で生じる摩擦のバランスについて図を用いて説明する。
図８は従来の紙葉類に作用する力や摩擦を示す説明図であり、（ａ）は上方から見た図で、（ｂ）は集積している様子を側方から見た図である。図９は２番目に繰出される紙葉類にモーメントが作用した場合を示す説明図である。
The balance of friction generated between paper sheets when this problem occurs will be described with reference to the drawings.
8A and 8B are explanatory views showing the force and friction acting on the conventional paper sheets. FIG. 8A is a view seen from above, and FIG. 8B is a view seen from the side of the accumulation. . FIG. 9 is an explanatory diagram showing a case where a moment acts on the second paper sheet fed out.
ステージ上に集積されている最上位の紙葉類Ｐ１を紙葉類搬送路に繰出すとき、ステージを移動させて集積されている紙葉類Ｐを繰出方向に沿った中心線の両側に配置した２つのピッカローラに押し付けてピッカローラを回転させる。
これによってピッカローラで押圧した紙葉類Ｐ１をフィードローラと分離ローラとの間に繰出す。
When the uppermost paper sheet P1 accumulated on the stage is fed out to the paper sheet conveyance path, the stage is moved and the accumulated paper sheets P are arranged on both sides of the center line along the feeding direction. The picker roller is rotated by pressing against the two picker rollers.
As a result, the paper sheet P1 pressed by the picker roller is fed between the feed roller and the separation roller.
図８において、点Ａ、点Ｂはステージを移動させて集積されている紙葉類Ｐをピッカローラに押し付けたときに、紙葉類Ｐにピッカローラからの押圧力Ｎが作用する点である。
Ｌはピッカローラ間の長さである。
μ１２Ａは、２番目に繰出される紙葉類Ｐ２の点Ａで生じる紙葉類Ｐ１との間の静摩擦係数である。
In FIG. 8, points A and B are points where the pressing force N from the picker roller acts on the paper sheet P when the accumulated paper sheet P is pressed against the picker roller by moving the stage. .
L is the length between the picker rollers.
μ12A is a coefficient of static friction with the paper sheet P1 generated at the point A of the paper sheet P2 fed out second.
μ１２Ｂは、紙葉類Ｐ２の点Ｂで生じる紙葉類Ｐ１との間の静摩擦係数である。
μ２３Ａは、紙葉類Ｐ２の点Ａで生じる３番目に繰出される紙葉類Ｐ３との間の静摩擦係数である。
μ２３Ｂは、紙葉類Ｐ２の点Ｂで生じる紙葉類Ｐ３との間の静摩擦係数である。
ここで、紙葉類Ｐ１を繰出したときに紙葉類Ｐ２の点Ａに作用する繰出方向に向かう力ＦＡは、
μ12B is a coefficient of static friction with the paper sheet P1 generated at the point B of the paper sheet P2.
μ23A is a coefficient of static friction with the third paper sheet P3 produced at the point A of the paper sheet P2.
μ23B is a coefficient of static friction with the paper sheet P3 generated at the point B of the paper sheet P2.
Here, when the paper sheet P1 is fed out, the force FA acting on the point A of the paper sheet P2 in the feeding direction is:
また、紙葉類Ｐ１を繰出したときに紙葉類Ｐ２の点Ｂに作用する繰出方向に向かう力ＦＢは、
Further, when the paper sheet P1 is fed out, the force FB acting in the feeding direction acting on the point B of the paper sheet P2 is:
ここで、図９に示すように紙葉類Ｐ２に力ＦＡによって点Ａが動き、力ＦＢが作用したが点Ｂが動かなかった場合、紙葉類Ｐ２には点Ｂを中心としたモーメントが発生して紙葉類Ｐ２の姿勢がずれてしまう。
Here, as shown in FIG. 9, when the point A moves to the paper sheet P2 by the force FA and the force FB acts but the point B does not move, the paper sheet P2 has a moment centered on the point B. It occurs and the posture of the paper sheet P2 shifts.
このように集積されている紙葉類間の摩擦により、繰出される紙葉類Ｐ１と共に動いてしまう紙葉類Ｐ２において、紙葉類Ｐ２の一方の側が繰出方向に動き、他方の側が動かなかった場合にモーメントが作用して紙葉類Ｐ２の姿勢が大きくずれてしまう。
本発明は、上記の問題点を解決するためになされたもので、２番目に繰出す紙葉類にモーメントが作用し、その紙葉類の姿勢が大きくずれてしまうことで紙葉類ジャム等の障害が発生することを防止する手段を提供することを目的とする。
In the paper sheet P2 that moves together with the fed paper sheet P1 due to the friction between the accumulated paper sheets in this way, one side of the paper sheet P2 moves in the feeding direction and the other side does not move. In this case, the moment acts and the posture of the paper sheet P2 is greatly deviated.
The present invention has been made to solve the above-described problems. A moment acts on the second paper sheet to be fed out, and the posture of the paper sheet greatly deviates. It is an object of the present invention to provide a means for preventing the occurrence of a failure.
本発明は、上記課題を解決するために、往復移動可能に構成され、紙葉類が集積されているステージと、前記紙葉類の繰出方向に沿った中心線の両側に配置され、前記紙葉類を繰出すピッカローラとを備えた紙葉類分離機構において、紙葉類を繰出すとき、前記ステージに集積されている紙葉類の前記ピッカローラより繰出方向の上流側を押圧する押圧手段を設けたことを特徴とする。 In order to solve the above problems, the present invention is configured to be capable of reciprocating movement, and is disposed on both sides of a stage on which paper sheets are stacked, and a center line along a feeding direction of the paper sheets, In a paper sheet separating mechanism provided with a picker roller that feeds out leaves, when feeding paper sheets, a pressure that presses the upstream side in the feeding direction of the paper sheets accumulated on the stage from the picker roller Means is provided.
これにより、本発明は、紙葉類を繰出すときにピッカローラよりも紙葉類の繰出方向の上流でステージに集積されている紙葉類の両側に荷重をかけることにより、紙葉類間で荷重のかかる箇所で摩擦が作用して繰出される紙葉類に引張られるように２番目に繰出される紙葉類の両側に繰出方向の力が作用するため、紙葉類の一方の側が動いて他方の側が動かないことで発生するモーメントによって紙葉類の姿勢が大きくずれてしまうのを防止して、紙葉類ジャム等の障害の発生を防止することができるという効果が得られる。 As a result, the present invention provides a load between the paper sheets by applying a load to both sides of the paper sheets accumulated on the stage upstream of the picker roller in the paper feeding direction when feeding the paper sheets. Since the force in the feeding direction acts on both sides of the second paper sheet fed so as to be pulled by the paper sheet fed out by friction at the place where the load is applied, one side of the paper sheet is It is possible to prevent the occurrence of a paper jam and the like by preventing the posture of the paper sheet from being greatly displaced due to the moment generated by the movement and the other side not moving.

μ２３Ｄは、紙葉類Ｐ２の点Ｄで生じる紙葉類Ｐ３との間の静摩擦係数である。
μ２３Ｅは、紙葉類Ｐ２の点Ｅで生じる紙葉類Ｐ３との間の静摩擦係数である。
ここで、紙葉類Ｐ１を繰出したときに紙葉類Ｐ２の点Ｄで繰出方向に作用する力ＦＤは、
μ12D is a coefficient of static friction with the paper sheet P1 generated at the point D of the paper sheet P2.

Here, when the paper sheet P1 is fed, the force FD acting in the feeding direction at the point D of the paper sheet P2 is:
また、紙葉類Ｐ１を繰出したときに紙葉類Ｐ２の点Ｅで繰出方向に作用する力ＦＥは、
Further, when the paper sheet P1 is fed out, the force FE acting in the feeding direction at the point E of the paper sheet P2 is:
図５に示す点Ｂが動かない場合を示す説明図に示すように、力ＦＢだけでは点Ｂが動かない場合、力ＦＤの点Ｄと点Ｂとを結ぶ直線方向の分力（以下、分力ＦＤ´という。）と、力ＦＥとの合力が点Ｂに作用する。
As shown in the explanatory view showing the case where the point B shown in FIG. 5 does not move, when the point B does not move only with the force FB, the component force in the linear direction connecting the point D and the point B of the force FD (hereinafter referred to as “minute”). The resultant force of the force FE and the force FE acts on the point B.
図５において、θは力ＦＤが作用する方向と点Ｄと点Ｂとを結ぶ直線との角度である。
分力ＦＤ´は、
In FIG. 5, θ is an angle between the direction in which the force FD acts and a straight line connecting point D and point B.

このようにして、紙葉類Ｐの繰出方向に沿った中心線の両側を押圧する押圧ローラ１２ａ、１２ｂを設け、紙葉類Ｐを繰出すときに押圧ローラ１２ａ、１２ｂで紙葉類Ｐを押圧して荷重をかけることにより、押圧ローラ１２ａ、１２ｂからの荷重がかかっている箇所の紙葉類Ｐ間で摩擦力が生じ、繰出される紙葉類Ｐ１に引張られるように紙葉類Ｐ２の点Ｄに力ＦＤおよび点Ｅに力ＦＥが作用するため、紙葉類Ｐ１を繰出したときに紙葉類Ｐ２の点Ｂに作用する力ＦＢが点Ｂを動かすことがない場合は、力ＦＤの分力ＦＤ´と力ＦＥとの合力Ｆ´Ｂが点Ｂに作用して点Ｂを動かすので、紙葉類Ｐ２にモーメントが作用するのを防止する。
In this way, the pressing rollers 12a and 12b that press both sides of the center line along the feeding direction of the paper sheet P are provided, and when the paper sheet P is fed, the pressing rollers 12a and 12b are used to push the paper sheet P into the paper sheet P. By pressing and applying a load, a frictional force is generated between the paper sheets P where the load from the pressing rollers 12a and 12b is applied, and the paper sheets P2 are pulled by the fed paper sheets P1. Since the force FD acts on the point D and the force FE acts on the point E, when the force FB acting on the point B of the paper sheet P2 does not move the point B when the paper sheet P1 is fed out, Since the resultant force F′B of the FD component force FD ′ and the force FE acts on the point B to move the point B, the moment is prevented from acting on the paper sheet P2.
以上説明したように、本実施例では、紙葉類の繰出方向に沿った中心線の両側を押し付ける押圧ローラを設け、紙葉類を繰出すときに押圧ローラで集積されている紙葉類を押圧して荷重をかけて紙葉類間に摩擦力を生じさせることにより、紙葉類を繰出したときに２番目に繰出される押圧ローラからの荷重がかかる紙葉類の両側に繰出方向の力が作用するため、紙葉類の一方の側が動いて他方の側が動かないことで発生するモーメントで紙葉類の姿勢が大きくずれてしまうのを防止するので、紙葉類ジャム等の障害の発生を防止する。 As described above, in this embodiment, the pressing rollers that press both sides of the center line along the feeding direction of the paper sheets are provided, and the paper sheets accumulated by the pressing roller when the paper sheets are fed out. By pressing and applying a load to generate a frictional force between the paper sheets, a load from the pressing roller that is secondly fed when the paper sheets are fed is applied to both sides of the paper sheets in the feeding direction. Because the force acts, it prevents the paper sheet from being greatly displaced due to the moment that occurs when one side of the paper sheet moves and the other side does not move. Prevent occurrence.

また、紙葉類Ｐを繰出すために集積した紙葉類をピッカローラ９ａ、９ｂに押し付けるようにステージ３を移動させるときは、ステージ３上に集積した紙葉類Ｐを押圧ローラ１２ａ、１２ｂが継続的に押し付けるようにステージ３の移動に合わせて同方向にビルプレッシャ部２０を移動させる。
When the sheets P are not accumulated, that is, after all the conveyed sheets P are accumulated or when the sheets P are not accumulated or fed out, they are accumulated on the stage 3 by the pressing rollers 12a and 12b. The bill pressure unit 20 is moved so as to press the paper sheet P that has been pressed.
When the stage 3 is moved so as to press the paper sheets accumulated to feed out the paper sheets P against the picker rollers 9a and 9b, the paper sheets P accumulated on the stage 3 are pressed by the pressing rollers 12a and 12b. The bill pressure unit 20 is moved in the same direction in accordance with the movement of the stage 3 so as to be continuously pressed.
以上説明したように、本実施例では、上記実施例１の効果に加えて、ビルプレッシャ部を設け、搬送された紙葉類を集積しているときは押圧ローラを集積している紙葉類から離すようにビルプレッシャ部を移動させておき、紙葉類の集積が終了した後に押圧ローラで集積した紙葉類を押圧する位置までビルプレッシャ部を移動させ、紙葉類の繰出しのためにステージがピッカローラの方に移動するときに、押圧ローラが紙葉類を継続して押圧するようにビルプレッシャ部をステージと同方向に移動させるようにしたので、紙葉類分離集積機構の振動等によって紙葉類収納部内に集積した紙葉類の姿勢が乱れてしまうのを防止できる。 As described above, in this embodiment, in addition to the effects of the first embodiment, when the paper pressure is provided and the conveyed paper sheets are stacked, the paper sheets on which the pressing rollers are stacked. The bill pressure part is moved so as to be away from the paper sheet, and after the paper sheets are collected, the bill pressure part is moved to a position where the paper sheets accumulated by the pressure roller are pressed, and the paper sheets are fed out. When the stage moves toward the picker roller, the bill pressure unit is moved in the same direction as the stage so that the pressure roller continues to press the paper. Thus, it is possible to prevent the posture of the paper sheets accumulated in the paper sheet storage unit from being disturbed.
なお、上記各実施例においては、押圧ローラアームにスプリングを取付けて押圧手段としての押圧ローラが紙葉類を５０〜１００ｇ程度の荷重で押圧するとして説明したが押圧手段は前記に限らず、押圧ローラの自重等で５０〜１００ｇ程度の荷重がかかるように押圧ローラアームに押圧ローラを取付けるようにしてもよい。 In each of the above embodiments, it has been described that a spring is attached to the pressing roller arm and the pressing roller as the pressing means presses the paper sheets with a load of about 50 to 100 g. The pressure roller may be attached to the pressure roller arm so that a load of about 50 to 100 g is applied due to the weight of the roller.
