第１載台２６は、バランスアーム１８の右端部の下面から下方へ延びる円柱状の支持ロッド２４の下端部に一体的に形成されている。つまり、第１載台２６の中央に支持ロッド２４の下端部が一体的に接合されている。また、第２載台２８には、上方へ向けて延びる円柱状の突起部２９が一体的に設けられている。 The first mounting table 26 is integrally formed at the lower end of a columnar support rod 24 that extends downward from the lower surface of the right end of the balance arm 18. That is, the lower end portion of the support rod 24 is integrally joined to the center of the first mounting base 26. Further, the second mounting base 28 is integrally provided with a columnar protrusion 29 extending upward.
図１、図２に示されるように、固定部２０は、バランスアーム１８の左端部の下面から前後に２個並んで下方へ延びる支持ロッド２２と、各支持ロッド２２の下端部に設けられたリング状ホルダー２３と、を有している。各リング状ホルダー２３が、被評価回転体の一例としての感光体ドラム４０の表面（外周面）を固定することにより、感光体ドラム４０が固定部２０に回転不能に固定されるようになっている。 As shown in FIG. 1 and FIG. 2, the fixing portion 20 is provided at the lower end of each support rod 22 and the support rods 22 that extend downward from the lower surface of the left end portion of the balance arm 18 in the front-rear direction. And a ring-shaped holder 23. Each ring-shaped holder 23 fixes the surface (outer peripheral surface) of the photosensitive drum 40 as an example of the rotating body to be evaluated, so that the photosensitive drum 40 is fixed to the fixing portion 20 in a non-rotatable manner. Yes.
なお、図３に示されるように、電子写真用の感光体ドラム４０は、導電性基体４２の上に、下引層４４が設けられ、下引層４４の上に、感光層としての電荷発生層４６及び電荷輸送層４８が順に設けられ、電荷輸送層４８の上に、耐摩耗特性の向上を目的とした表面層としての表面保護層５０が設けられて構成されている。 As shown in FIG. 3, the electrophotographic photosensitive drum 40 is provided with an undercoat layer 44 on a conductive substrate 42, and charge generation as a photosensitive layer is performed on the undercoat layer 44. A layer 46 and a charge transport layer 48 are provided in this order, and a surface protective layer 50 is provided on the charge transport layer 48 as a surface layer for the purpose of improving wear resistance.
また、図１、図２に示されるように、摩耗装置１０は、固定部２０に固定された感光体ドラム４０の軸方向でもある前後方向略中央部（前後のリング状ホルダー２３の間）の直下に配置された摩耗輪３０を有している。摩耗輪３０は、ゴム製の円板状とされており、その外周面（表面）に、例えば酸化アルミニウムが添加されたポリエステルフィルムが貼り付けられて構成されている。 Also, as shown in FIGS. 1 and 2, the wear device 10 has a substantially central portion in the front-rear direction (between the front and rear ring-shaped holders 23) that is also the axial direction of the photosensitive drum 40 fixed to the fixing portion 20. It has a wear ring 30 arranged immediately below. The wear ring 30 is formed in a rubber disc shape, and is configured by adhering, for example, a polyester film to which aluminum oxide is added to the outer peripheral surface (surface) thereof.
より具体的に言えば、摩耗輪３０は、テーバー社製の摩耗輪（商品名ＣＳ−０）の外周面に、１ｃｍ幅に切断された３Ｍ社製のラッピングフィルムが両面テープによって貼り付けられて構成されている。なお、後述するように、摩耗輪３０の外周面（ラッピングフィルム）の粒度（粒径）と摩耗輪３０の外周面に掛かる幅１ｃｍ当たりの質量（分銅３８の質量）との積は、６０μｍ・ｇ以下となることが望ましい。そして、摩耗輪３０の外周面（ラッピングフィルム）の粒度は、３μｍ以下とされることが望ましい。 More specifically, the wear ring 30 is formed by attaching a 3M wrapping film cut to a width of 1 cm to the outer peripheral surface of a Taber wear ring (trade name CS-0) with a double-sided tape. It is configured. As will be described later, the product of the particle size (particle size) of the outer peripheral surface (wrapping film) of the wear wheel 30 and the mass per 1 cm width (mass of the weight 38) applied to the outer peripheral surface of the wear wheel 30 is 60 μm · g or less is desirable. And it is desirable for the particle size of the outer peripheral surface (wrapping film) of the wear ring 30 to be 3 μm or less.
また、摩耗輪３０の前方側における架台１２上には、支持台１３が一体的に設けられており、その支持台１３上には、駆動源の一例としての駆動モーター３２が設けられている。そして、駆動モーター３２から後方へ向かって延びる回転軸３４が、摩耗輪３０の軸心部（回転中心部）に固定されている。 A support base 13 is integrally provided on the gantry 12 on the front side of the wear wheel 30, and a drive motor 32 as an example of a drive source is provided on the support base 13. A rotation shaft 34 extending rearward from the drive motor 32 is fixed to the axial center portion (rotation center portion) of the wear wheel 30.
これにより、摩耗輪３０は、駆動モーター３２の回転駆動力により、予め決められた回転速度（例えば１２０ｒｐｍ）で回転駆動される構成になっている。そして、摩耗輪３０の外周面は、感光体ドラム４０の表面層（表面保護層５０）に接触しつつ回転することで、その感光体ドラム４０の少なくとも表面層（表面保護層５０）の一部を摩耗させるようになっている。 Thus, the wear wheel 30 is configured to be rotationally driven by a rotational driving force of the drive motor 32 at a predetermined rotational speed (for example, 120 rpm). The outer peripheral surface of the wear ring 30 rotates while being in contact with the surface layer (surface protective layer 50) of the photoconductive drum 40, so that at least a part of the surface layer (surface protective layer 50) of the photoconductive drum 40 is obtained. Is supposed to wear out.
また、第１載台２６には、１つ又は複数の分銅３６が載せられるようになっており、感光体ドラム４０との水平バランス（平衡）が取られるようになっている。なお、分銅３６は、支持ロッド２４の外径よりも若干大きい切欠部（図示省略）を有する平面視略「Ｃ」字状に形成されており、その切欠部に支持ロッド２４を通すことで第１載台２６上に配置されるようになっている。 Further, one or a plurality of weights 36 are placed on the first mounting table 26, and a horizontal balance (equilibrium) with the photosensitive drum 40 is taken. The weight 36 is formed in a substantially “C” shape in plan view having a notch (not shown) that is slightly larger than the outer diameter of the support rod 24. It is arranged on the first stage 26.
また、第２載台２８には、１つ又は複数の分銅３８が載せられるようになっており、感光体ドラム４０の摩耗輪３０に対する接触圧が調整されるようになっている。つまり、感光体ドラム４０は、摩耗輪３０に対して常に一定の荷重で接触する構成になっている。なお、分銅３８は、中心に突起部２９の外径よりも若干大きい孔が形成されており、その孔に突起部２９を通すことで第２載台２８上に配置されるようになっている。 In addition, one or a plurality of weights 38 are placed on the second mounting table 28, and the contact pressure of the photosensitive drum 40 with respect to the wear wheel 30 is adjusted. That is, the photosensitive drum 40 is configured to always contact the wear wheel 30 with a constant load. The weight 38 has a hole formed in the center thereof that is slightly larger than the outer diameter of the protrusion 29, and is arranged on the second mounting base 28 by passing the protrusion 29 through the hole. .
バランスアーム１８は、移動ステージ１６により、その高さ位置が調節可能になっている。すなわち、移動ステージ１６は、ネジ部１５を緩めて支柱１４に沿ってスライドさせ、適切な位置でネジ部１５を締め付けることにより、その位置で固定されるようになっている。これにより、摩耗輪３０に対する感光体ドラム４０の高さ位置が調節可能となる構成になっており、感光体ドラム４０の外径が異なったときでも対応可能になる構成になっている。 The balance arm 18 can be adjusted in height by the moving stage 16. That is, the moving stage 16 is fixed at that position by loosening the screw portion 15 and sliding it along the support column 14 and tightening the screw portion 15 at an appropriate position. As a result, the height position of the photosensitive drum 40 with respect to the wear wheel 30 can be adjusted, and even when the outer diameter of the photosensitive drum 40 is different, it is possible to cope with it.
以上のような構成とされた本実施形態に係る摩耗装置１０において、次にその作用（摩耗方法）について説明する。 Next, the operation (wear method) of the wear apparatus 10 according to the present embodiment configured as described above will be described.
まず、バランスアーム１８の左端部に設けられた固定部２０に感光体ドラム４０を吊り下げた状態に固定する（吊下工程）。すなわち、固定部２０のリング状ホルダー２３により、感光体ドラム４０の表面を固定する。そして、移動ステージ１６の上端部１７にバランスアーム１８の長手方向中央部を支持させるとともに、バランスアーム１８の右端部に設けられた第１載台２６に１つ又は複数の分銅３６を載せ（荷重を調整し）、感光体ドラム４０との水平バランスを取る（平衡工程）。 First, the photosensitive drum 40 is fixed in a suspended state to a fixing portion 20 provided at the left end portion of the balance arm 18 (suspending step). That is, the surface of the photosensitive drum 40 is fixed by the ring-shaped holder 23 of the fixing unit 20. The upper end portion 17 of the moving stage 16 is supported by the central portion in the longitudinal direction of the balance arm 18, and one or more weights 36 are placed on the first platform 26 provided at the right end portion of the balance arm 18 (load) To achieve a horizontal balance with the photosensitive drum 40 (equilibrium process).
その後、移動ステージ１６のネジ部１５を緩め、移動ステージ１６を支柱１４に沿って下方へ移動させ、摩耗輪３０の外周面に対して感光体ドラム４０の表面が接触する適切な位置にてネジ部１５を締め付け、支柱１４に対する移動ステージ１６の位置を決める。つまり、感光体ドラム４０の外径寸法に応じて、バランスアーム１８の高さ位置を調節する（調節工程）。 Thereafter, the screw part 15 of the moving stage 16 is loosened, the moving stage 16 is moved downward along the support column 14, and the screw is screwed at an appropriate position where the surface of the photosensitive drum 40 contacts the outer peripheral surface of the wear ring 30. The part 15 is tightened to determine the position of the moving stage 16 with respect to the column 14. That is, the height position of the balance arm 18 is adjusted according to the outer diameter size of the photosensitive drum 40 (adjustment process).
その後、バランスアーム１８の左端部における上面に設けられた第２載台２８に１つ又は複数の分銅３８を載せ（荷重を調整し）、感光体ドラム４０の摩耗輪３０に対する接触圧を調整する（調整工程）。そして、駆動モーター３２により、摩耗輪３０を予め決められた回転速度（例えば１２０ｒｐｍ）で回転させ、感光体ドラム４０の少なくとも表面層（表面保護層５０）の一部を、後述する表面粗さ測定装置によって摩耗痕の深さが測定可能になるまで摩耗させる（摩耗工程）。 Thereafter, one or a plurality of weights 38 is placed on the second stage 28 provided on the upper surface of the left end portion of the balance arm 18 (the load is adjusted), and the contact pressure of the photosensitive drum 40 with respect to the wear wheel 30 is adjusted. (Adjustment process). Then, the wear wheel 30 is rotated at a predetermined rotation speed (for example, 120 rpm) by the drive motor 32, and at least a part of the surface layer (surface protective layer 50) of the photosensitive drum 40 is measured for surface roughness described later. Wear until the depth of the wear mark is measurable by the device (wear process).
こうして、感光体ドラム４０の少なくとも表面層（表面保護層５０）の一部が摩耗されたら、その摩耗痕の深さを、例えば東京精密社製の表面粗さ測定装置によって測定する。これにより、耐摩耗特性の向上が求められている感光体ドラム４０において、その摩耗特性が評価可能になる。 Thus, when at least a part of the surface layer (surface protective layer 50) of the photosensitive drum 40 is worn, the depth of the wear mark is measured by a surface roughness measuring device manufactured by Tokyo Seimitsu Co., Ltd., for example. This makes it possible to evaluate the wear characteristics of the photoreceptor drum 40 that is required to have improved wear resistance characteristics.
本実施形態に係る摩耗装置１０を用いて感光体ドラムの摩耗特性の評価を行うためには、その摩耗装置１０の測定値と実機摩耗量との間に相関関係があることが必要である。そこで、その相関関係を把握する仕方について説明する。まず、複数の実機摩耗量が異なる感光体ドラムを用意する。例えば、タイプの異なる感光体ドラムを５個用意する。なお、各感光体ドラムは、同じタイプの各感光体ドラムにより、実機を使用して長時間掛けて摩耗され、そのときの摩耗痕の深さを回転数で割った値が「実機摩耗量」として予め求められている。表１に、その実機摩耗量（実際の摩耗量）を示す。 In order to evaluate the wear characteristics of the photosensitive drum using the wear device 10 according to this embodiment, it is necessary that there is a correlation between the measured value of the wear device 10 and the actual wear amount. Therefore, a method of grasping the correlation will be described. First, a plurality of photosensitive drums having different actual wear amounts are prepared. For example, five photosensitive drums of different types are prepared. Each photoconductor drum is worn by a photoconductor drum of the same type over a long period of time using an actual machine, and the value obtained by dividing the depth of the wear scar at that time by the number of revolutions is `` actual machine wear amount '' As previously obtained. Table 1 shows the actual wear amount (actual wear amount).
一方、本実施形態に係る摩耗装置１０によって、Ｔｙｐｅ１〜Ｔｙｐｅ５までの各感光体ドラムを、それぞれ測定条件を変えて摩耗する。具体的には、Ｔｙｐｅ１〜Ｔｙｐｅ５までの各感光体ドラムにおいて、それぞれラッピングフィルム（摩耗輪３０の外周面）の粒度と、そのラッピングフィルム（摩耗輪３０の外周面）に掛かる幅１ｃｍ当たりの荷重、即ち第２載台２８に載せる分銅３８の質量との組み合わせを適宜変更して摩耗する。表２に、その摩耗痕の深さを回転数で割った値を「摩耗量」として示す。 On the other hand, the wear device 10 according to the present embodiment wears the photosensitive drums of Type 1 to Type 5 while changing the measurement conditions. Specifically, in each photosensitive drum from Type 1 to Type 5, the particle size of the wrapping film (the outer peripheral surface of the wear wheel 30) and the load per 1 cm width applied to the wrapping film (the outer peripheral surface of the wear wheel 30), That is, the combination with the mass of the weight 38 placed on the second mounting table 28 is changed as appropriate to cause wear. Table 2 shows a value obtained by dividing the depth of the wear scar by the number of rotations as “amount of wear”.
表１及び表２から、ラッピングフィルムの粒度が９μｍで、第２載台２８に載せる分銅の質量が５０ｇとされている場合の摩耗量と実機摩耗量との関係を図６に示す。この結果から、ラッピングフィルムの粒度が９μｍで、第２載台２８に載せる分銅の質量が５０ｇの場合には、摩耗量と実機摩耗量との相関関係（比例関係）が得られないことが判る。 From Tables 1 and 2, FIG. 6 shows the relationship between the amount of wear and the actual amount of wear when the particle size of the wrapping film is 9 μm and the mass of the weight placed on the second stage 28 is 50 g. From this result, it can be seen that when the particle size of the wrapping film is 9 μm and the mass of the weight placed on the second stage 28 is 50 g, the correlation (proportional relationship) between the wear amount and the actual machine wear amount cannot be obtained. .
また、表１及び表２から、ラッピングフィルムの粒度が９μｍで、第２載台２８に載せる分銅の質量が３０ｇとされている場合の摩耗量と実機摩耗量との関係を図７に示す。この結果から、ラッピングフィルムの粒度が９μｍで、第２載台２８に載せる分銅の質量が３０ｇの場合にも、摩耗量と実機摩耗量との相関関係（比例関係）が得られないことが判る。 Further, from Tables 1 and 2, FIG. 7 shows the relationship between the amount of wear and the actual amount of wear when the particle size of the wrapping film is 9 μm and the mass of the weight placed on the second stage 28 is 30 g. From this result, it can be seen that even when the particle size of the wrapping film is 9 μm and the mass of the weight placed on the second stage 28 is 30 g, the correlation (proportional relationship) between the wear amount and the actual machine wear amount cannot be obtained. .
更に、表１及び表２から、ラッピングフィルムの粒度が３μｍで、第２載台２８に載せる分銅の質量が５０ｇとされている場合の摩耗量と実機摩耗量との関係を図８に示す。この結果から、ラッピングフィルムの粒度が３μｍで、第２載台２８に載せる分銅の質量が５０ｇの場合にも、摩耗量と実機摩耗量との相関関係（比例関係）が得られないことが判る。 Further, from Tables 1 and 2, FIG. 8 shows the relationship between the wear amount and the actual wear amount when the particle size of the wrapping film is 3 μm and the weight of the weight placed on the second stage 28 is 50 g. From this result, it can be seen that even when the particle size of the wrapping film is 3 μm and the mass of the weight placed on the second stage 28 is 50 g, the correlation (proportional relationship) between the wear amount and the actual machine wear amount cannot be obtained. .
一方、表１及び表２から、ラッピングフィルムの粒度が３μｍで、第２載台２８に載せる分銅の質量が２０ｇとされている場合の摩耗量と実機摩耗量との関係を図４に示す。この結果から、ラッピングフィルムの粒度が３μｍで、第２載台２８に載せる分銅の質量が２０ｇの場合には、摩耗量と実機摩耗量との相関関係（比例関係）が得られることが判る。 On the other hand, from Tables 1 and 2, FIG. 4 shows the relationship between the amount of wear and the actual amount of wear when the particle size of the wrapping film is 3 μm and the weight of the weight placed on the second stage 28 is 20 g. From this result, it can be seen that when the particle size of the wrapping film is 3 μm and the mass of the weight placed on the second stage 28 is 20 g, a correlation (proportional relationship) between the wear amount and the actual machine wear amount is obtained.
更に、表１及び表２から、ラッピングフィルムの粒度が１μｍで、第２載台２８に載せる分銅の質量が５０ｇとされている場合の摩耗量と実機摩耗量との関係を図５に示す。この結果から、ラッピングフィルムの粒度が１μｍで、第２載台２８に載せる分銅の質量が５０ｇの場合には、摩耗量と実機摩耗量との相関関係（比例関係）が得られることが判る。 Further, from Tables 1 and 2, FIG. 5 shows the relationship between the amount of wear and the actual amount of wear when the particle size of the wrapping film is 1 μm and the weight of the weight placed on the second stage 28 is 50 g. From this result, it can be seen that when the particle size of the wrapping film is 1 μm and the mass of the weight placed on the second stage 28 is 50 g, a correlation (proportional relationship) between the wear amount and the actual machine wear amount is obtained.
以上のことから、摩耗輪３０の外周面に貼り付けられたラッピングフィルムの粒度と、第２載台２８に載せる分銅３８の質量（摩耗輪３０の外周面に貼り付けられたラッピングフィルムに掛かる幅１ｃｍ当たりの質量）との積が、６０μｍ・ｇ以下とされている場合に、摩耗量と実機摩耗量との相関関係が得られることが推測される。そして特に、ラッピングフィルムの粒度が、３μｍ以下とされている場合に、摩耗量と実機摩耗量との相関関係が得られることが推測される。 From the above, the particle size of the wrapping film attached to the outer peripheral surface of the wear wheel 30 and the mass of the weight 38 placed on the second mounting base 28 (the width applied to the wrapping film attached to the outer peripheral surface of the wear wheel 30). It is presumed that a correlation between the wear amount and the actual machine wear amount can be obtained when the product with the mass per 1 cm is 60 μm · g or less. And especially when the particle size of the wrapping film is 3 μm or less, it is presumed that a correlation between the wear amount and the actual wear amount can be obtained.
すなわち、このような条件下で、評価対象となる感光体ドラム４０の少なくとも表面層（表面保護層５０）の一部を摩耗装置１０で摩耗して、その摩耗量を算出すれば、図４又は図５に示される「摩耗量」と「実機摩耗量」との相関関係（仮想線で示す比例関係）を表したグラフから、その感光体ドラム４０において、実際に実機にて長時間掛けて摩耗させなくても、その実機での実際の摩耗量（実機摩耗量）が推定される。 That is, if at least a part of the surface layer (surface protective layer 50) of the photosensitive drum 40 to be evaluated is worn by the wear device 10 under such conditions and the amount of wear is calculated, FIG. From the graph showing the correlation (proportional relationship indicated by the phantom line) between “amount of wear” and “amount of actual machine wear” shown in FIG. 5, the photosensitive drum 40 is actually worn for a long time on the actual machine. Even if not, the actual wear amount (actual machine wear amount) in the actual machine is estimated.
このように、本実施形態によれば、図４又は図５に示される「摩耗量」と「実機摩耗量」との相関関係（比例関係）を表したグラフを用いることにより、実際に実機を使用して感光体ドラム４０を摩耗させて摩耗特性を評価する場合に比べて、感光体ドラム４０の摩耗特性を精度よく、かつ短時間（約５分〜１０分）で効率よく評価可能になる。 Thus, according to this embodiment, the actual machine is actually used by using the graph showing the correlation (proportional relationship) between the “wear amount” and the “actual machine wear amount” shown in FIG. 4 or 5. Compared to the case where the wear characteristic is evaluated by using the photoconductive drum 40 and the wear characteristic is evaluated, the wear characteristic of the photoconductive drum 40 can be evaluated with high accuracy and in a short time (about 5 to 10 minutes). .
しかも、本実施形態によれば、バランスアーム１８の高さ位置を調節可能なように、支柱１４に対してスライド可能とされた移動ステージ１６を有しているため、バランスアーム１８の高さ位置が調節可能に構成されていない場合に比べて、感光体ドラム４０の外径が異なるときでも評価が可能になる。 In addition, according to the present embodiment, since the movable stage 16 is slidable with respect to the support column 14 so that the height position of the balance arm 18 can be adjusted, the height position of the balance arm 18 can be adjusted. Can be evaluated even when the outer diameter of the photosensitive drum 40 is different from that in the case where is not configured to be adjustable.
以上、本実施形態に係る摩耗装置１０及び摩耗方法について、図面を基に説明したが、本実施形態に係る摩耗装置１０及び摩耗方法は、図示のものに限定されるものではなく、本発明の要旨を逸脱しない範囲内において、適宜設計変更可能なものである。例えば、被評価回転体としては、感光体ドラム４０に限定されるものではなく、図示しない帯電ロール、転写ロール又は定着ロール等でも同様に評価可能である。 The wear device 10 and the wear method according to the present embodiment have been described with reference to the drawings. However, the wear device 10 and the wear method according to the present embodiment are not limited to the illustrated ones, and The design can be changed as appropriate without departing from the scope of the invention. For example, the rotor to be evaluated is not limited to the photosensitive drum 40, and a charging roll, a transfer roll, a fixing roll or the like (not shown) can be similarly evaluated.
