【発明の属する技術分野】
本発明はプリンタ−，ファクシミリ，複写機などに使用される導電性ゴムロ−ラ−を回転しながら電気抵抗値が自動測定される導電性ゴムロ−ラ−の抵抗値測定装置に関する。
【０００２】
【従来の技術】
図６は従来の導電性ゴムロ−ラ−（６）の抵抗値測定冶具を示す図であり、これについて説明する。前記抵抗値測定冶具は、ゴムロ−ラ−（６）を載せて測定するためのアルミニウム板と、デジタル抵抗測定器（４）と、ゴムロ−ラ−（６）の芯材に載せる所定重量の錘とから成り、且つアルミニウム板の一端に電極を立設させてデジタル抵抗測定器（４）と接続させる。この抵抗値測定冶具を用いてゴムロ−ラ−（６）の抵抗値を測定する場合には、測定者が先ず始めにゴムロ−ラ−（６）をアルミニウム板の上に載せると共に両端から突出する芯材に所定荷重、例えば３００ｇを加える。そしてゴムロ−ラ−（６）の芯材に他の電極を接続させる。その後、電圧印加して測定され、測定者が記録紙に記録していた。例えば１０００ボルトを電圧印加して１０秒後の値が測定され、その値が記録されていた。この時の測定箇所は、ゴムロ−ラ−（６）の周方向の接触部を９０度或いは１２０度毎に回転させて３〜４箇所測定する測定方法であった。そして、前記測定値が全て規格範囲に入っているか測定者が判定して不良品を除去していた。
【０００３】
【発明が解決しようとする課題】
しかしながら前記手作業によるゴムロ−ラ−（６）の測定は、測定者が手でゴムロ−ラ−（６）の周方向を目視で３〜４箇所回転させ且つその周方向に於ける複数箇所の接触部の測定値を記録紙に記録するため、測定者によって周方向のセット位置のバラツキやセットの仕方などで測定条件が変わり易く、しかも手でゴムロ−ラ−（６）の外周を回転させながら測定するため、手間が掛り、測定作業能率が悪かった。更にゴムロ−ラ−（６）の周方向のセット位置が変わると抵抗値も変わる場合もあるため、その値がゴムロ−ラ−（６）全体の抵抗値と異なる場合が生じ、測定し直すと良品になったり、或いは不良品になったりして不安定要素があると共に且つ神経を使う仕事である等の問題点があった。
【０００４】
尚、前記ゴムロ−ラ−（６）の測定としては、安定した測定値が得られるように自動測定することが困難であるため、ゴムロ−ラ−（６）の自動測定装置は今までになかった。しかも、ゴムロ−ラ−（６）の使用状態と同じように回転しながら測定値を測定する装置も今までにはなかった。
【０００５】
本発明はゴムロ−ラ−を回転させながら且つ測定を自動化させて安定した測定値が得られると共に使用状態に近付けた測定が可能となる導電性ゴムロ−ラ−の抵抗値測定装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記問題点を解決するために本発明は成されたものであり、つまり、ゴムロ−ラ−と密着させて回転しながら電圧印加する金属製の測定ロ−ラ−と、ゴムロ−ラ−の両端を支持する一対の受けロ−ラ−とを少なくとも有した測定部材が機体の上部に設けられ、該機体には、ゴムロ−ラ−を１本ずつ測定ロ−ラ−に搬送する搬送機が備えられ、且つ、ゴムロ−ラ−の芯材端部と測定ロ−ラ−の軸端部に接続させて抵抗値を測定するデジタル抵抗測定器が少なくとも具備された構造と成す。
【０００７】
【発明の実施の形態】
図１、図２は本発明の実施形態を示す図であり、これに基づいて説明する。（１）は機体であり、その下部にはキャスタ−（11）が取付けられている。（２）は機体（１）の上部に設けられた測定部材であり、該測定部材（２）には、ゴムロ−ラ−（６）を１本ずつ下方に当接させて回転しながら電圧印加する金属製の測定ロ−ラ−（21）と、該測定ロ−ラ−（21）の両端が軸支された軸受（22a）を下部に固着する取付板（22）と、その取付板（22）の上面に取付けると共に前記測定ロ−ラ−（21）に取付けたプ−リ−（21a）とベルト（23a）を介して接続させる駆動モ−タ−（23）と、前記取付板（22）と共に前記測定ロ−ラ−（21）を機体（１）から浮上させるための取付板浮上手段（24）と、前記ゴムロ−ラ−（６）の両端を支持する一対の受けロ−ラ−（25）と、前記ゴムロ−ラ−（６）に所定圧を加えるための加圧用錘（26）とがある。また前記測定ロ−ラ−（21）にはアルミニウム製，鉄製，銅製，銀製などの金属製のロ−ラ−を用いると良いが、特にはアルミニウム製のロ−ラ−が好ましい。更に前記取付板浮上手段（24）は、前記取付板（22）の四隅を貫通させ且つ前記機体（１）から立設する支持棒（24a）と、該各支持棒（24a）に挿入して取付けると共に前記機体（１）と前記取付板（22）の間に配置され、前記取付板（22）を浮上させるためのコイルスプリングである支持バネ（24b）と、前記取付板（22）の両側に吊設させたバランスウエイト（24c）とから成されている。前記受けロ−ラ−（25）は前記機体（１）に取付けたロ−ラ−支持板（25a）に２個軸支されている。又、前記加圧用錘（ 26 ）は図１に示すように前記取付板（22）の上面に載せる１個のブロック状のものでも良いが、両側に設けたバランスウエイト（24c）の上に載せるものとしても良い。
【０００８】
（３）はゴムロ−ラ−（６）を１本ずつ測定ロ−ラ−（21）へ搬送するために機体（１）に備えられた搬送機であり、該搬送機（３）には、前記機体（１）の一端側から前記測定ロ−ラ−（21）付近まで平行に配置すると共に上辺に二等辺三角形状波を連続させて設けた長尺で一対の固定片（31）と、該固定片（31）と略同形で且つ上辺の三角波を不等辺三角形状に形成させると共にその谷部が前記固定片（31）の頂点から搬送方向へずらせてそれぞれに配置した一対の可動片（32）と、その可動片（32）を上下動させて前記谷部が前記固定片（31）の頂点まで持上げられるための上下移動用シリンダ−（33）とがある。前記固定片（31）は前記機体（１）の上部で且つ内側に配置され、更にその内側には可動片（32）が配置されると共に一対の可動片（32）は前記上下移動用シリンダ−（33）によって同時に上下動する。尚、前記可動片（32）の配置は固定片（31）の内側に限定されるものではない。（４）はゴムロ−ラ−（６）の芯材端部と前記測定ロ−ラ−（21）の軸端部に接続させて抵抗値を測定するために具備されたデジタル抵抗測定器である。（５）は制御装置であり、該制御装置（５）には、印加電圧値や測定物による抵抗値の規格範囲の設定或いは電圧印加時間や測定しない時間（以降、マスキング時間と言う）などを予め測定前に打込む入力機能があり、デジタル抵抗測定器（４）からの出力デ−タ−値が抵抗値の規格範囲に入っているか否かを判定したり、測定箇所の数に応じて測定ロ−ラ−（21）の速度を制御したりする機能なども有している。
【０００９】
次に本発明品の使用方法について説明する。先ず始めにゴムロ−ラ−（６）の両端を受けロ−ラ−（25）にセットする。そして取付板（22）の両側にバランスウエイト（24c）を吊設させて測定ロ−ラ−（21）がゴムロ−ラ−（６）に力が加わらずに接触するゼロバランス状態にする。その後、所定圧がゴムロ−ラ−（６）に加わるために加圧用錘（26）を取付板（22）の上面に載せる。又、印加電圧値，抵抗値の規格範囲の設定，電圧印加時間，マスキング時間などを予め制御装置（５）に入力しておく。次にゴムロ−ラ−（６）の周方向に於ける複数箇所の接触部の抵抗値を自動測定する。この時、ゴムロ−ラ−（６）の周方向の測定は電圧を印加させて所定時間（例えば２秒）後に測定するが、ゴムロ−ラ−（６）を連続回転させながら、測定開始位置から少しずつずらして測定すると最大８０箇所まで測定可能であるが、測定箇所としては仕様に応じて２０〜５０箇所の測定が好ましい。又、自動測定中で判定結果がNGとなった場合には、ブザ−或いは表示プリントにNG表示で知らせると共に図示しない機構のものによって取除かれる。測定後、判定結果がOKのものは別の場所に搬送されると共に次に測定するゴムロ−ラ−（６）が搬送機（３）によって受けロ−ラ−（25）にセットされる。そして上記と同様に測定するのである。このようにしてゴムロ−ラ−（６）を自動測定すると、１時間当り従来方法では６０本前後しか測定できなかったものが、本発明装置を用いて行うと、３６０本以上測定出来るものとなった。
【００１０】
図５はゴムロ−ラ−（６）が搬送機（３）によって１本ずつ受けロ−ラ−（25）まで搬送される作用を示す図であり、これについて説明する。先ず始めにゴムロ−ラ−（６）を搬送機（３）の端部に乗せる。するとゴムロ−ラ−（６）の両側の芯材が固定片（31）の山形の谷部に架設される［図５（ａ）、図１参照］。次に上下移動用シリンダ−（33）が作動し、可動片（32）を水平状態のまま上昇させ、可動片（32）の頂点がゴムロ−ラ−（６）の芯材の左側に近付き、更に頂点が上昇すると、ゴムロ−ラ−（６）の芯材は可動片（32）側に移り、且つ頂点の右側から図中の矢印のように谷部まで自動的に移動する［図５（ｂ）参照］。そして可動片（32）が直ぐに降下すると、ゴムロ−ラ−（６）の芯材は可動片（32）の谷部から固定片（31）の頂点右側に移動した後、図中の矢印のように谷部へ自動的に移動し、始めに乗せた谷部から隣の谷部へ搬送されるのである［図５（ｃ）参照］。次に可動片（32）が上昇すると、ゴムロ−ラ−（６）の芯材は固定片（31）から可動片（32）の右側の谷部に移動した後、可動片（32）が降下し始めると、ゴムロ−ラ−（６）の芯材は固定片（31）の右隣の谷部に移動し、順次右側へ搬送されるのである。以上の動作を繰返して、固定片（31）の端部までゴムロ−ラ−（６）が搬送される。搬送後、ゴムロ−ラ−（６）が固定片（31）の頂点から最終の谷部に図中の点線矢印のように移動すると、ゴムロ−ラ−（６）は回転したまま、右下に配置された１組の受けロ−ラ−（25）の上に図中の矢印のように移動して配置されるのである［図５（ｄ）、図３、図４参照］。尚、この時、前記測定ロ−ラ−（ 21 ）は取付板浮上手段（ 24 ）によってゼロバランス状態から所定重量の加圧用錘（ 26 ）が載せて加圧され且つ回転している。このため、ゴムロ−ラ−（６）が搬送機（３）から受けロ−ラ−（ 25 ）にセットされる際は、測定ロ−ラ−（ 21 ）と受けロ−ラ−（ 25 ）との間がゴムロ−ラ−（６）の外形よりも狭い状態となるが、ゴムロ−ラ−（６）が測定ロ−ラ−（ 21 ）に接触すると、該測定ロ−ラ−（ 21 ）の回転力でゴムロ−ラ−（６）を巻込むと共に測 定ロ−ラ−（ 21 ）が適宜に浮上するので、確実にゴムロ−ラ−（６）は受けロ−ラ−（ 25 ）の上に乗り且つ測定ロ−ラ−（ 21 ）と密着された状態で自動的にセットされるものとなる。またゴムロ−ラ−（６）は搬送機（３）の端部に乗せる場合は、固定片（31）の全ての谷部にゴムロ−ラ−（６）が架設されるように順次乗せる。
【００１１】
【発明の効果】
本発明はこのように構成させたことにより、下記に記載する効果を有する。
【００１２】
請求項１のようにゴムロ−ラ−（６）と密着させて回転しながら電圧印加する金属製の測定ロ−ラ−（21）と、ゴムロ−ラ−（６）の両端を支持する一組で且つ一対の受けロ−ラ−（25）とを少なくとも有した測定部材（２）が機体（１）の上部に設けられ、該機体（１）にはゴムロ−ラ−（６）を１本ずつ測定ロ−ラ−（21）に搬送する搬送機（３）が備えられ、且つゴムロ−ラ−（６）の芯材端部と測定ロ−ラ−（21）の軸端部に接続させて抵抗値を測定するデジタル抵抗測定器（４）が少なくとも具備された構成とすることにより、プリンタ−，ファクシミリ，複写機などで実際に使用される状態と略同じ条件下で測定値が得られると共にゴムロ−ラ−（６）の周方向の適宜角度毎で接触部の抵抗値が自動測定され、ゴムロ−ラ−（６）の周ムラも測定出来るため、従来の如き測定者による測定条件のバラツキも殆どなく安定した測定値が得られると共に従来の如き測定者が手でゴムロ−ラ−（６）の周方向を目視で回転させながら測定値を記録する必要がなくなったので、測定時間が大幅に短縮され且つ大量のゴムロ−ラ−（６）を測定することが可能となった。
【００１３】
請求項２のように測定部材（２）として、ゴムロ−ラ−（６）を当接させて回転しながら電圧印加する測定ロ−ラ−（21）と、該測定ロ−ラ−（21）の両端を軸支させる取付板（22）と、測定ロ−ラ−（21）を回転させる駆動モ−タ−（23）と、測定ロ−ラ−（21）を機体（１）から浮上させるために少なくとも支持バネ（24b）とバランスウエイト（24c）を備えた取付板浮上手段（24）と、ゴムロ−ラ−（６）を支持する受けロ−ラ−（25）と、ゴムロ−ラ−（６）に所定圧を加えるための加圧用錘（26）とから構成したものを用いることにより、従来の如き各ゴムロ−ラ−（６）毎に測定条件を設定することなく、始めにセットしておけば、同一条件下でゴムロ−ラ−（６）を連続させて自動測定することが可能となる。しかもゴムロ−ラ−（６）が連続回転されながら抵抗値を得るので、ゴムロ−ラ−（６）を実機に装着させた状態と略同一の測定となり、より適確な測定値が得られるものとなる。
【００１４】
請求項３に示すように搬送機（３）として、機体（１）の一端側から測定ロ−ラ−（21）付近まで平行に配置すると共に上辺に三角波を連続させて設けた長尺で一対の固定片（31）と、該固定片（31）と略同形で且つ上辺の三角波の谷部が固定片（31）の頂点から搬送方向へずらせて配置した一対の可動片（32）と、その可動片（32）を上下動させて谷部が固定片（31）の頂点まで持上げられるための上下移動用シリンダ−（33）とから構成したものを使用することにより、一端側の固定片（31）からその谷部にゴムロ−ラ−（６）の芯材を乗せるだけで、測定部材（２）にゴムロ−ラ−（６）が順に送られて行くので、パ−トの作業者が一人いれば簡単に且つ正確な測定が可能となる。
【００１５】
請求項４に示すように測定部材（２）によるゴムロ−ラ−（６）の出力デ−タ−を基に良否の判断や測定条件などを制御する制御装置（５）を備えることにより、ゴムロ−ラ−（６）の測定条件が簡単に入力することが可能となり、熟練した測定技術が不要であるため、誰にでも本発明装置を操作することが可能となる。又、導電性を有したゴムロ−ラ−（６）の周方向の適宜角度毎に抵抗値が自動測定でき且つ測定回数が８０箇所まで自由に選択調整できると共にゴムロ−ラ−（６）の周ムラも測定出来るものとなる。

TECHNICAL FIELD OF THE INVENTION

[Prior art]
FIG. 6 is a view showing a resistance measuring jig of a conventional conductive rubber roller (6), which will be described. The resistance measuring jig comprises an aluminum plate for mounting and measuring a rubber roller (6), a digital resistance measuring instrument (4), and a weight having a predetermined weight to be mounted on a core material of the rubber roller (6). And an electrode is provided upright on one end of the aluminum plate and connected to the digital resistance measuring instrument (4). When measuring the resistance of the rubber roller (6) using this resistance measuring jig, the measurer first places the rubber roller (6) on an aluminum plate and projects from both ends. A predetermined load, for example, 300 g is applied to the core material. Then, another electrode is connected to the core material of the rubber roller (6). Thereafter, the measurement was performed by applying a voltage, and the measurer recorded on the recording paper. For example, a value 10 seconds after applying a voltage of 1000 volts was measured and the value was recorded. At this time, three or four measurement points were measured by rotating the circumferential contact portion of the rubber roller (6) every 90 degrees or 120 degrees. Then, the measurer determined whether or not all the measured values were within the standard range, and removed defective products.
[0003]
[Problems to be solved by the invention]
However, the measurement of the rubber roller (6) by the above-mentioned manual operation is carried out by manually measuring the circumferential direction of the rubber roller (6) by manually rotating the rubber roller (3) three to four places and measuring a plurality of positions in the circumferential direction. Since the measured value of the contact portion is recorded on the recording paper, the measurement conditions are easily changed by the measurer depending on the variation of the set position in the circumferential direction and the setting method, and the outer periphery of the rubber roller (6) is rotated by hand. Since the measurement was performed while the measurement was being performed, it was troublesome and the measurement work efficiency was poor. Further, if the set position of the rubber roller (6) in the circumferential direction changes, the resistance value may also change. Therefore, the value may be different from the resistance value of the entire rubber roller (6). There have been problems such as a non-defective product or a defective product, which has an unstable factor and is a work that uses nerves.
[0004]
Since it is difficult to measure the rubber roller (6) automatically so as to obtain a stable measurement value, there is no automatic measuring device for the rubber roller (6). Was. In addition, there has not been an apparatus that measures a measured value while rotating in the same manner as the use state of the rubber roller (6).
[0005]
An object of the present invention is to provide a conductive rubber roller resistance value measuring device that can obtain a stable measured value while rotating a rubber roller and automate the measurement, and can perform a measurement close to a use state. With the goal.

Next, the vertical movement cylinder (33) is operated to raise the movable piece (32) in a horizontal state, and the top of the movable piece (32) approaches the left side of the core of the rubber roller (6). When the apex further rises, the core material of the rubber roller (6) moves to the movable piece (32) side and automatically moves from the right side of the apex to the valley as shown by the arrow in the figure [FIG. b)]. When the movable piece (32) immediately descends, the core of the rubber roller (6) moves from the valley of the movable piece (32) to the right side of the vertex of the fixed piece (31), as shown by the arrow in the figure. The valley is automatically moved to the first valley, and is conveyed from the first valley to the next valley [see FIG. 5 (c)]. Next, when the movable piece (32) rises, the core material of the rubber roller (6) moves from the fixed piece (31) to the valley on the right side of the movable piece (32), and then the movable piece (32) descends. When the operation is started, the core material of the rubber roller (6) moves to the valley on the right side of the fixing piece (31) and is sequentially conveyed to the right. By repeating the above operation, the rubber roller (6) is transported to the end of the fixed piece (31). After the transfer, when the rubber roller (6) moves from the vertex of the fixed piece (31) to the final valley as shown by the dotted arrow in the figure, the rubber roller (6) rotates and moves to the lower right. It is moved and arranged as shown by the arrow in FIG. 5 on a set of arranged receiver rollers (25) [see FIGS. 5 (d), 3 and 4]. At this time, the measuring roller ( 21 ) is pressed and rotated by the mounting plate floating means ( 24 ) with a predetermined weight of the pressing weight ( 26 ) placed thereon from the zero balance state . For this reason, when the rubber roller (6) is set on the receiving roller ( 25 ) from the transporter (3) , the measuring roller ( 21 ) and the receiving roller ( 25 ) are connected to each other. between the Gomuro - La - becomes a narrower state than the outer shape of (6), Gomuro - La - upon contact with (21), the measurement b - - (6) is measured b - La La - (21) a rotational force Gomuro - La - since (21) floats on the appropriately ensure Gomuro - - (6) measuring with a entangle Teiro - La La - (6) receives b - La - (25) above the And is automatically set in a state of being in close contact with the measurement roller ( 21 ). When the rubber roller (6) is mounted on the end of the transporter (3), the rubber roller (6) is sequentially mounted on all the valleys of the fixed piece (31) such that the rubber roller (6) is installed.
