Description
本発明は、紙葉送りローラ及び紙葉送り装置に関する。 The present invention relates to a paper sheet feeding roller and a paper sheet feeding device.
紙葉送り装置は、プリンタ、ファックス等のＯＡ機器に使用され、紙葉を送り出す機能を有している。例えば、特許文献１に開示されている紙葉類搬送用ローラは、支持体の外周側にローラ本体を取り付けて構成する。ローラ本体は、支持体との間に空洞を形成するように配置した筒状部と、筒状部の軸方向における両端それぞれに連設したリング状の側壁とを備える。支持体の外周面に、２本の環状溝と、各環状溝から分岐する第１及び第２の分岐溝を設ける。側壁の内周縁部２は環状溝に嵌合する。内周縁に軸方向両側に突出する第１及び第２の突出部を設ける。突出部は、分岐溝に嵌合する。 The paper sheet feeder is used for OA devices such as printers and fax machines, and has a function of feeding paper sheets. For example, a paper sheet conveying roller disclosed in Patent Document 1 is configured by attaching a roller body to the outer peripheral side of a support. The roller main body includes a cylindrical portion disposed so as to form a cavity between the roller body and a ring-shaped side wall provided continuously at both ends in the axial direction of the cylindrical portion. Two annular grooves and first and second branch grooves branched from each annular groove are provided on the outer peripheral surface of the support. The inner peripheral edge 2 of the side wall is fitted into the annular groove. First and second projecting portions projecting on both sides in the axial direction are provided on the inner peripheral edge. The protrusion fits into the branch groove.
特許文献１の記載によれば、側壁の内周縁部に設けられた突出部又は凹部が、環状溝に設けられた凹部又は突出部に嵌合することにより、ローラ本体が支持体に対して周方向に滑り回転することが防止される。 According to the description of Patent Document 1, the protrusion or recess provided on the inner peripheral edge of the side wall is fitted into the recess or protrusion provided in the annular groove, so that the roller body is surrounded by the support. It is prevented from sliding in the direction.
ところで、この種の紙葉類搬送用ローラを用いた紙葉送り装置では、紙葉に対して、ねじりや、蛇行を生じさせることなく、ローラの回転方向に素直に送りが係ることが必要である。そのためには、ローラから紙葉の表面に印加される圧力（弾性圧力）が、ローラの全幅に亘って、位置的な変動を生じることなく、均一になることが要求される。 By the way, in this type of paper sheet feeding device using a paper sheet conveying roller, it is necessary to directly feed the paper sheet in the rotational direction without twisting or meandering. is there. For this purpose, the pressure (elastic pressure) applied from the roller to the surface of the paper sheet is required to be uniform over the entire width of the roller without causing positional fluctuations.
ところが、特許文献１で代表される従来の紙葉類搬送用ローラは、ローラの軸方向の両端に支持片を配置した構造であるため、支持片の連接する部分において、紙葉類に対する圧力が大きくなり、その中間部で圧力が低下する中だるみの加圧特性となり易くい。このため、ローラ幅方向で見た紙葉類に対する圧力が不均一となり、紙葉送りにねじりや蛇行を生じさせることがあった。 However, the conventional paper sheet transport roller represented by Patent Document 1 has a structure in which support pieces are arranged at both ends in the axial direction of the roller. It becomes large, and it is easy to have a moderate pressurization characteristic in which the pressure drops in the middle part. For this reason, the pressure with respect to the paper sheet viewed in the roller width direction becomes non-uniform, which may cause twisting and meandering in the paper sheet feeding.
本発明の課題は、紙葉を、ねじりや、蛇行を生じさせることなく、直線的に送ることができる紙葉送りローラ及び紙葉送り装置を提供することである。 An object of the present invention is to provide a paper sheet feeding roller and a paper sheet feeding device capable of feeding a paper sheet linearly without causing twisting or meandering.
上述した課題を解決するため、本発明に係る紙葉送りローラは、紙葉接触部と、第１支持片と、第２支持片とを含む。前記紙葉接触部、前記第１支持片及び前記第２支持片は、弾力性を有する部材よりなり、内部に空洞を有する連続体でなる。前記紙葉接触部は、円筒状であって、その外周面が紙葉接触面を構成し、前記第１支持片及び前記第２支持片は、互いに間隔を隔て、前記紙葉接触部の軸方向の両端縁からその内側に距離をおいて、前記紙葉接触部の内面に立設され、軸心の周りに軸孔を有する。 In order to solve the above-described problem, the paper sheet feeding roller according to the present invention includes a paper sheet contact portion, a first support piece, and a second support piece. The paper sheet contact portion, the first support piece, and the second support piece are made of an elastic member, and are a continuous body having a cavity inside. The paper sheet contact portion has a cylindrical shape, and an outer peripheral surface thereof constitutes a paper sheet contact surface, and the first support piece and the second support piece are spaced apart from each other, and the shaft of the paper sheet contact portion A distance from the both end edges in the direction to the inside thereof is provided on the inner surface of the paper sheet contact portion, and an axial hole is formed around the axis.
上述した紙葉送りローラは、支持体と組み合わされ、紙葉送り装置を構成する。両者の組み合わせにおいて、第１支持片及び第２支持片の内周縁が、ローラ支持体に設けられた凹溝に嵌め込まれる。 The paper sheet feeding roller described above is combined with a support to constitute a paper sheet feeding device. In the combination of both, the inner peripheral edges of the first support piece and the second support piece are fitted into the concave grooves provided in the roller support.
ここで、本発明に係る紙葉送りローラにおいて、紙葉接触部及び支持片は、弾力性を有する部材により構成され、内部に空洞を有する連続体を構成する。従って、紙葉に対して広い接触面積をもって圧接し、紙葉送りを確実に行うことができる。 Here, in the paper sheet feeding roller according to the present invention, the paper sheet contact portion and the support piece are constituted by a member having elasticity, and constitute a continuous body having a cavity inside. Therefore, the sheet can be pressed against the sheet with a wide contact area, and the sheet can be reliably fed.
紙葉接触部は、紙葉接触面となる円筒状の外周面を構成する。紙葉接触部は、通常、紙葉送りに必要な摩擦力を得るためのトレッドパターンを有するから、紙葉に圧接した紙葉送りローラは、適当な摩擦力を獲得し、紙葉送りを確実に行うことができる。 The paper sheet contact portion constitutes a cylindrical outer peripheral surface serving as a paper sheet contact surface. Since the paper sheet contact section usually has a tread pattern for obtaining the frictional force necessary for paper sheet feeding, the paper sheet feeding roller in pressure contact with the paper sheet obtains an appropriate friction force and ensures paper sheet feeding. Can be done.
第１支持片及び第２支持片は、紙葉接触部の内面に立設され、軸心の周りに軸孔を有する。紙葉送り装置を構成するに当たり、第１支持片及び第２支持片の軸孔を取り巻く内周縁が、ローラ支持体に設けられた凹溝に嵌め込まれ、紙葉送りローラの有する弾力性により、第１支持片及び第２支持片の内周縁が、支持体の凹溝に圧縮された状態で弾性的に密着する。従って、紙葉送りローラの回転軸方向への位置ずれ防止とともに、回転方向への滑りを阻止し得る。 The first support piece and the second support piece are erected on the inner surface of the paper sheet contact portion and have an axial hole around the axis. In configuring the paper sheet feeding device, the inner peripheral edge surrounding the shaft hole of the first support piece and the second support piece is fitted in the concave groove provided in the roller support, and due to the elasticity of the paper sheet feed roller, The inner peripheral edges of the first support piece and the second support piece are in close contact with each other in a compressed state in the concave groove of the support body. Accordingly, it is possible to prevent the paper sheet feeding roller from being displaced in the rotational axis direction and to prevent slipping in the rotational direction.
更に、本発明において、第１支持片及び第２支持片は、互いに間隔を隔て、紙葉接触部の軸方向の両端縁からその内側に距離をおいて、紙葉接触部の内面に立設されている。この構造によれば、従来、紙葉類に対する圧力が低下する傾向にあった中間部で、圧力低下が鈍くなり、従来、紙葉類に対する圧力が大きくなるローラの幅方向の両端で、圧力が低下する。このため、ローラ幅方向で見た紙葉類に対する圧力が均一化され、紙葉送りにねじりや蛇行が生じ難くなる。よって、紙葉を、ねじりや、蛇行を生じさせることなく、ローラの回転方向に直線的に送ることができるようになる。 Further, in the present invention, the first support piece and the second support piece are erected on the inner surface of the paper sheet contact portion at a distance from the both end edges in the axial direction of the paper sheet contact portion to the inside thereof at a distance from each other. Has been. According to this structure, the pressure drop is slow at the intermediate portion where the pressure on the paper sheet has conventionally been apt to decrease, and the pressure is conventionally reduced at both ends in the width direction of the roller where the pressure on the paper sheet is increased. descend. For this reason, the pressure on the paper sheet viewed in the roller width direction is made uniform, and twisting and meandering are less likely to occur in the paper sheet feeding. Therefore, the paper sheet can be fed linearly in the rotation direction of the roller without twisting or meandering.
以上述べたように、本発明によれば、紙葉を、ねじりや、蛇行を生じさせることなく、直線的に送ることができる紙葉送りローラ及び紙葉送り装置を提供することができる。 As described above, according to the present invention, it is possible to provide a paper sheet feeding roller and a paper sheet feeding device that can feed a paper sheet linearly without causing twisting or meandering.
本発明の他の目的、構成及び利点については、添付図面を参照し、更に詳しく説明する。添付図面は、単に、例示に過ぎない。 Other objects, configurations and advantages of the present invention will be described in more detail with reference to the accompanying drawings. The accompanying drawings are merely examples.

For the elastic member, a resin material such as natural rubber, synthetic rubber, low-hardness rubber, or soft plastic is preferably used. The paper sheet contact portion 1, the first support piece 31, and the second support piece 32 constitute a cylindrical continuous body having a cavity 53 inside. The paper sheet contact portion 1 has a cylindrical outer peripheral surface 111 serving as a paper sheet contact surface. The sheet contact portion 1 has a width W as viewed in the width direction parallel to the axis O1.
第１支持片３１及び第２支持片３２は、互いに間隔Ｗｘを隔て、紙葉接触部１の軸心Ｏ１と平行な幅方向の両端縁１０１，１０２からその内側に距離ΔＷ１１、ΔＷ１２をおいて、紙葉接触部１の内面１１２に立設されている。軸心Ｏ１の周りには、軸孔５１，５２が開口しており、軸孔５１，５２は第１支持片３１及び第２支持片３２の内周縁３１１，３２１によって囲まれている。 The first support piece 31 and the second support piece 32 are spaced apart from each other by a distance Wx, and distances ΔW11 and ΔW12 are provided on the inner side from both end edges 101 and 102 in the width direction parallel to the axis O1 of the paper sheet contact portion 1. The sheet contact portion 1 is erected on the inner surface 112. Shaft holes 51 and 52 are opened around the shaft center O <b> 1, and the shaft holes 51 and 52 are surrounded by inner peripheral edges 311 and 321 of the first support piece 31 and the second support piece 32.
第１支持片３１及び第２支持片３２は、内周縁３１１，３２１に向かうにつれて、両者３１−３２間の間隔Ｗｘが拡大する方向に傾斜している。別の見方として、紙葉接触部１の幅方向の端縁１０１，１０２に対する距離で見ると、第１支持片３１は、その立設位置である距離ΔＷ１１が最大となり、第２支持片３２は、その立設位置である距離ΔＷ１２が最大となるように傾斜している。第１支持片３１及び第２支持片３２の内周縁３１１，３２１は、断面角形のリング状であり、その内側に空洞５３に連なる軸孔５１，５２が設けられている。 The 1st support piece 31 and the 2nd support piece 32 incline in the direction where the space | interval Wx between both 31-32 expands as it goes to the inner periphery 311,321. As another way of viewing, when viewed from the distance with respect to the edge 101, 102 in the width direction of the paper sheet contact portion 1, the first support piece 31 has the maximum distance ΔW11 as its standing position, and the second support piece 32 is Further, the inclination is such that the distance ΔW12 which is the standing position is maximized. Inner peripheral edges 311 and 321 of the first support piece 31 and the second support piece 32 are ring-shaped with a square cross section, and shaft holes 51 and 52 that are continuous with the cavity 53 are provided inside thereof.
紙葉接触部１の外周面１１１には、図３に例示するように、トレッドパターン１１３が形成されていてもよい。もっとも、図示のトレッドパターン１１３は、一例示に過ぎないのであって、例えば、波線状、格子状又は突起状等、図示と異なる態様であってもよい。また、図１及び図２参照で既に暗示されているように、トレッドパターン１１３は、紙葉接触部１の材質選定により、適当な摩擦力を得ることができれば、必ずしも設けられなくともよい。 A tread pattern 113 may be formed on the outer peripheral surface 111 of the paper sheet contact portion 1 as illustrated in FIG. However, the illustrated tread pattern 113 is merely an example, and may be in a different form from that illustrated, for example, a wavy line shape, a lattice shape, or a protrusion shape. 1 and 2, the tread pattern 113 is not necessarily provided as long as an appropriate frictional force can be obtained by selecting the material of the paper sheet contact portion 1.
更に、第１支持片３１及び第２支持片３２の内周縁３１１，３２１は、図４に例示するように、断面円弧状であってもよい。図１〜図４の実施の形態において、内周縁３１１，３２１は、外側の位置が、紙葉接触部１の両端縁１０１，１０２の位置と一致しているが、一致することは必須ではない。 Furthermore, the inner peripheral edges 311 and 321 of the first support piece 31 and the second support piece 32 may have an arcuate cross section as illustrated in FIG. In the embodiment shown in FIGS. 1 to 4, the inner peripheral edges 311 and 321 have the outer positions that coincide with the positions of both end edges 101 and 102 of the paper sheet contact portion 1, but it is not essential. .
２．紙葉送り装置
上述した紙葉送りローラは、支持体と組み合わされて、紙葉送り装置を構成する。図５は本発明に係る紙葉送り装置の正面断面図である。図において、図１〜図４に示した構成部分と同一の構成部分には、同一の参照符号を付し、重複説明を省略する。
2. Paper Sheet Feeding Device The paper sheet feeding roller described above is combined with a support to constitute a paper sheet feeding device. FIG. 5 is a front sectional view of the paper sheet feeder according to the present invention. In the figure, the same components as those shown in FIGS. 1 to 4 are denoted by the same reference numerals, and redundant description is omitted.
図示する紙葉送り装置は、第１紙葉送りローラ７１と、第２紙葉送りローラ７２と、ローラ支持体９とを含む。第１及び第２紙葉送りローラ７１、７２は、図１〜図４に記載された紙葉送りローラの何れかである。実施の形態では、第１及び第２紙葉送りローラ７１、７２は、２個であるが、その個数は任意である。１個であってもよいし、３個以上であってもよい。 The illustrated sheet feeding device includes a first sheet feeding roller 71, a second sheet feeding roller 72, and a roller support 9. The first and second paper sheet feeding rollers 71 and 72 are any of the paper sheet feeding rollers shown in FIGS. In the embodiment, the number of the first and second paper sheet feeding rollers 71 and 72 is two, but the number is arbitrary. One may be sufficient and three or more may be sufficient.
第１及び第２紙葉送りローラ７１、７２は、第１支持片３１及び第２支持片３２の内周縁３１１，３２１のそれぞれが、ローラ支持体９に設けられた凹溝９２１，９２２のそれぞれに密着して嵌め込まれている。 The first and second paper sheet feeding rollers 71 and 72 are configured so that inner peripheral edges 311 and 321 of the first support piece 31 and the second support piece 32 are respectively recessed grooves 921 and 922 provided in the roller support body 9. It is fitted in close contact with.
図６は、本発明に係る紙葉送り装置の使用状態を示す図である。図６では、作業台１７に載置された状態の紙葉１５を、矢印Ｙの方向に送るようになっている。図の紙葉送り装置は、ローラ支持体９の軸孔９１に回転軸１３を装着してあり、この回転軸１３を、駆動装置（図示しない）より矢印Ｒ１で示す方向に回転駆動する。 FIG. 6 is a diagram illustrating a usage state of the paper sheet feeder according to the present invention. In FIG. 6, the paper sheet 15 placed on the work table 17 is sent in the direction of arrow Y. In the illustrated sheet feeding device, a rotation shaft 13 is mounted in a shaft hole 91 of a roller support 9, and the rotation shaft 13 is rotationally driven by a drive device (not shown) in a direction indicated by an arrow R1.
ここで、紙葉送りローラ７１，７２において、紙葉接触部１、第１支持片３１及び第２支持片３２は、弾力性を有する部材により構成され、内部に空洞５３を有する連続体であるから、紙葉１５に対して広い接触面積をもって圧接し、紙葉１５を確実に送ることができる。 Here, in the paper sheet feeding rollers 71 and 72, the paper sheet contact portion 1, the first support piece 31, and the second support piece 32 are formed of elastic members and are continuous bodies having a cavity 53 therein. Therefore, the sheet 15 can be pressed and contacted with a wide contact area, and the sheet 15 can be reliably sent.
紙葉接触部１は、紙葉接触面となる円筒状の外周面１１１を有するとともに、空洞５３を有する。従って、紙葉１５と紙葉送りローラ７１，７２との間に、紙葉送りローラ７１，７２の弾力性と、空洞５３の存在による撓みにより、適切な摩擦力を生じさせ、紙葉１５を確実に送ることができる。 The paper sheet contact portion 1 has a cylindrical outer peripheral surface 111 serving as a paper sheet contact surface and a cavity 53. Therefore, an appropriate frictional force is generated between the paper sheet 15 and the paper sheet feeding rollers 71 and 72 due to the elasticity of the paper sheet feeding rollers 71 and 72 and the bending due to the presence of the cavity 53, thereby Can be sent reliably.
また、第１支持片３１及び第２支持片３２の内周縁３１１，３２１が、ローラ支持体９に設けられた凹溝９２１，９２２に嵌め込まれ、紙葉送りローラ７１，７２の有する弾力性により、第１支持片３１及び第２支持片３２の内周縁３１１，３２１が、ローラ支持体９の凹溝９２１，９２２に圧縮された状態で弾性的に密着する。従って、紙葉送りローラ７１，７２の回転軸方向への位置ずれ防止とともに、回転方向への滑りを阻止し得る。 Further, the inner peripheral edges 311 and 321 of the first support piece 31 and the second support piece 32 are fitted into the concave grooves 921 and 922 provided in the roller support body 9, and due to the elasticity of the paper sheet feeding rollers 71 and 72. The inner peripheral edges 311 and 321 of the first support piece 31 and the second support piece 32 are elastically brought into close contact with the recessed grooves 921 and 922 of the roller support 9. Accordingly, it is possible to prevent the sheet feeding rollers 71 and 72 from being displaced in the rotational axis direction and to prevent slipping in the rotational direction.
更に、本発明において、第１支持片３１及び第２支持片３２は、互いに間隔Ｗｘを隔て、紙葉接触部１の軸方向の両端縁１０１，１０２からその内側に距離ΔＷ１１、ΔＷ１２をおいて、紙葉接触部１の内面１１２に立設されている。この構造によれば、従来、紙葉１５に対する圧力が低下する傾向にあった中間部で、圧力低下が鈍くなり、従来、紙葉１５に対する圧力が大きくなる紙葉送りローラ７１，７２の幅方向の両端で、圧力が低下する。このため、ローラ幅方向で見た紙葉１５に対する加圧力が均一化され、紙葉送りにねじりや蛇行が生じ難くなる。よって、紙葉１５を、ねじりや、蛇行を生じさせることなく、紙葉送りローラ７１，７２の回転方向Ｒ１に一致する矢印Ｙの方向に直線的に送ることができるようになる。 Further, in the present invention, the first support piece 31 and the second support piece 32 are spaced apart from each other by a distance Wx, with a distance ΔW11, ΔW12 inside the edge contact edges 101, 102 in the axial direction of the paper sheet contact portion 1. The sheet contact portion 1 is erected on the inner surface 112. According to this structure, in the width direction of the sheet feeding rollers 71 and 72, the pressure drop becomes dull at an intermediate portion where the pressure on the paper sheet 15 has conventionally been apt to decrease. The pressure drops at both ends. For this reason, the pressure applied to the paper sheet 15 as viewed in the roller width direction is made uniform, and twisting and meandering are less likely to occur in the paper sheet feeding. Therefore, the paper sheet 15 can be linearly fed in the direction of the arrow Y coinciding with the rotation direction R1 of the paper sheet feeding rollers 71 and 72 without causing twisting or meandering.
図１〜図４に示したように、第１支持片３１及び第２支持片３２が、内周縁３１１，３２１に向かうにつれて、両者３１−３２間の間隔Ｗｘを拡大させる方向に傾斜している場合には、上述した加圧力の均一化が促進され、紙葉１５に対する直線送りがより高度化される。 As shown in FIGS. 1-4, the 1st support piece 31 and the 2nd support piece 32 incline in the direction which expands the space | interval Wx between both 31-32, as it goes to the inner periphery 311,321. In this case, the above-described uniform pressure is promoted, and the linear feed to the paper sheet 15 is further advanced.
ローラ支持体９は、空洞５３から外気に連なる空気流通路９３を有する。この構造によれば、空洞５３の内部の空気を空気流通路９３から換気できるから、空洞５３の形状を変化させることができる。従って、紙葉１５の厚みの変化に対応して適当な圧接力、及び、摩擦力を確保することができる。 The roller support 9 has an air flow passage 93 that communicates with the outside air from the cavity 53. According to this structure, since the air inside the cavity 53 can be ventilated from the air flow passage 93, the shape of the cavity 53 can be changed. Accordingly, it is possible to ensure an appropriate pressing force and frictional force corresponding to the change in the thickness of the paper sheet 15.
本発明に係る紙葉送りローラ７は、図７に図示するように、給紙ローラ１９と向き合わせ、紙葉送りローラ７と給紙ローラ１９との間で紙葉１５を挟み、紙葉１５に対して、矢印Ｙの方向の送りをかける紙送り装置に適用することもできる。 As shown in FIG. 7, the sheet feeding roller 7 according to the present invention faces the sheet feeding roller 19, sandwiches the sheet 15 between the sheet feeding roller 7 and the sheet feeding roller 19, and the sheet 15 In contrast, the present invention can also be applied to a paper feeding device that feeds in the direction of arrow Y.
以上、好ましい実施例を参照して本発明の内容を具体的に説明したが、本発明の基本的技術思想、及び、教示に基づいて、当業者であれば、種種の変形態様を採り得ることは自明である。 Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention.
