Abstract
Description
本発明は、ゴムローラの表面に粉体を塗布し、粉体層を形成するローラの製造方法に関するものである。 The present invention relates to a roller manufacturing method in which powder is applied to the surface of a rubber roller to form a powder layer.
円筒形状の部材に粉を均一に塗布する技術がある（例えば、特許文献１参照）。しかし、ゴムローラ表面に粉を均一に塗布するだけで、粉体が擦り込まれた状態の紛体層は形成できない。初期には粉体がゴムローラへ良好に付着し、ローラ表面に平滑性に優れた粉体層が形成されるが、耐久時には粉体層が良好に保持されず、この方法だけでは、ゴムローラ表面に粉体層を確実に形成することはできない。 There is a technique for uniformly applying powder to a cylindrical member (for example, see Patent Document 1). However, it is not possible to form a powder layer in which the powder is rubbed by simply applying the powder uniformly to the rubber roller surface. Initially, the powder adheres well to the rubber roller, and a powder layer with excellent smoothness is formed on the roller surface.However, the powder layer does not hold well during durability, and this method alone does not adhere to the rubber roller surface. The powder layer cannot be reliably formed.
即ち、ゴムローラ上に異物質の付着低減効果を有する粉体を塗布する場合、塗布状態により耐久時の付着低減効果は大きく変わり、各種紛体を単に塗布しただけでは画像評価で耐久を進めるにつれて、付着低減効果が薄れてしまうという問題もあった。また、目視または表面粗さにより塗布状態の判断ができない場合にも、付着低減効果に大きな差が出てしまうので、塗布後の付着低減効果を判断することは困難であった。
本発明は、ゴムローラの表面に粉体を塗布し、粉体層を形成し、表面平滑性および付着性を向上させることを目的としている。 An object of this invention is to apply | coat powder to the surface of a rubber roller, to form a powder layer, and to improve surface smoothness and adhesiveness.

本発明のゴムローラ製造方法によれば、ゴムローラに粉体を付着させる粉付け工程、粉付けされたゴムローラの粉体を擦り込む仮粉拭き工程、仮粉拭きされたゴムローラを仕上げ拭きする仕上げ拭き工程により、表面平滑性、付着性の良い粉体層が形成できる。 According to the rubber roller manufacturing method of the present invention, a powdering process for adhering powder to the rubber roller, a temporary powder wiping process for rubbing the powdered rubber roller powder, and a final wiping process for finishing and wiping the rubber roller wiped with the temporary powder. Thus, a powder layer having good surface smoothness and adhesion can be formed.
芯金と、その外周に形成された弾性層および被覆層を有するゴムローラの製造方法において、ゴムローラ表面に粉体（好ましくはハイドロタルサイト）を付着させる粉付け工程、布（例えば東レ社製）と弾性体による仮粉拭き工程、布と弾性体による仕上げ拭き工程を経て、ゴムローラ表面に粉体層を形成する。 In a method of manufacturing a rubber roller having a cored bar and an elastic layer and a coating layer formed on the outer periphery thereof, a powdering process for attaching powder (preferably hydrotalcite) to the surface of the rubber roller, a cloth (for example, manufactured by Toray Industries, Inc.) A powder layer is formed on the surface of the rubber roller through a temporary powder wiping process using an elastic body and a finishing wiping process using a cloth and an elastic body.
その際に、粉付け工程は、接触式または、非接触式でゴムローラ表面に均一に粉をつけることが好ましい。粉が不均一にゴムローラに付着すると、ゴムローラ表面がむらになったり、付着低減効果が発揮でない場合がある。そのために、粉を載せる弾性ローラＡと粉貯め部を有しており、該粉貯め部のバイブレーションにより該弾性ローラＡ上に粉を載せる手段、或いは、該弾性ローラＡに粉を供給する弾性ローラＢと粉貯め部を有しており、該粉貯め部に弾性ローラを押し付けるまたは、粉貯め部を弾性ローラに押し付ける手段がある。ただし、弾性ローラＡは、弾性体が好ましいが、表面に粘着層を持つ弾性ローラが尚好ましい。また、弾性ローラＡに粉の凝集物が付着すると、拭きムラになったりするために、弾性ローラＡ且つ、弾性ローラＢ、または、弾性ローラＡ或いは、Ｂにならし機構を付加し、弾性ローラＡまたは、Ｂ表面の粉を均一にすることが望ましい。 At that time, it is preferable that the powdering step is a contact type or non-contact type, and the powder is uniformly applied to the surface of the rubber roller. If the powder adheres unevenly to the rubber roller, the surface of the rubber roller may become uneven or the effect of reducing adhesion may not be exhibited. For this purpose, it has an elastic roller A for placing powder and a powder storage part, and means for placing powder on the elastic roller A by vibration of the powder storage part, or an elastic roller for supplying powder to the elastic roller A B and a powder storage part, and there is means for pressing the elastic roller against the powder storage part or pressing the powder storage part against the elastic roller. However, the elastic roller A is preferably an elastic body, but an elastic roller having an adhesive layer on the surface is still more preferable. In addition, if powder agglomerates adhere to the elastic roller A, wiping unevenness may occur. Therefore, the elastic roller A and the elastic roller B, or the elastic roller A or a leveling mechanism are added to the elastic roller A. It is desirable to make the powder on the A or B surface uniform.
仮粉拭き、仕上げ拭き工程では、ゴムローラ表面の塗布された粉体をゴムローラ表面に均一に擦り込むことが好ましい。仮粉拭き工程、仕上げ拭き工程は、微細な隙間を有する布および布の内側に弾性体を配置した拭き部をゴムローラの円周方向に対して直角に押し当てる押し当て機構と拭き部をゴムローラの円周方向に対して平行に、スライドさせるスライド機構で構成された拭き手段がある。ゴムローラと拭き部の平行度が重要であり、そのために、ガイドを使ったスライド機構などが挙げられるが、拭き部押し当て力が１Ｎなどの時には、ガイド等を使う方式では、力を均一に制御が困難である。そのために、１Ｎ〜５Ｎの範囲に置いては、ベアリング軸を用いた振り子式の押し当て方式にすることが望ましい。スライド機構部では、どうしても、ゴムローラの端部の拭き状態と中央の拭き状態が変化してしまうために、拭き部がゴムローラ端面から拭き部長さの１／３以上オーバーランさせることが望ましい。 In the temporary powder wiping and finishing wiping steps, it is preferable to uniformly rub the powder applied on the surface of the rubber roller onto the surface of the rubber roller. The temporary powder wiping process and the finishing wiping process consist of a cloth having a fine gap and a wiping part with an elastic body arranged on the inside of the cloth perpendicular to the circumferential direction of the rubber roller. There is a wiping means composed of a slide mechanism that slides in parallel to the circumferential direction. The parallelism between the rubber roller and the wiping part is important. For this reason, a slide mechanism using a guide can be cited. However, when the wiping part pressing force is 1N, etc., the force is controlled uniformly with the method using a guide. Is difficult. Therefore, in the range of 1N to 5N, it is desirable to adopt a pendulum type pressing method using a bearing shaft. In the slide mechanism section, the wiping state at the end of the rubber roller and the wiping state at the center are inevitably changed, so it is desirable that the wiping portion overruns １ ／ or more of the length of the wiping portion from the end surface of the rubber roller.
本発明のローラの製造方法を電子写真装置の帯電ローラの製造方法に適用した実施例を図面を参照して説明する。 An embodiment in which the method for producing a roller of the present invention is applied to a method for producing a charging roller of an electrophotographic apparatus will be described with reference to the drawings.

Example 1
As shown in FIG. 1, the dusting part is formed of a foam that supplies powder (8) to an elastic roller A (2) (Technoroll A-452-G) whose surface is composed of an adhesive layer. It consists of a roller B (3) and a powder storage part (4). The elastic roller B (3) is pressed against the powder storage part (4) by an elastic roller B moving cylinder (7), and the elastic roller B (3) Top up with powder. Urethane plate (9) was used as a smoothing mechanism so that there was no aggregation of powder in elastic roller B (3), and powder on the surface of elastic roller B was smoothed (see FIG. 3). After replenishment, as shown in FIG. 2, the elastic roller B (3) is pressed against the elastic roller A (2) at 500 g in a pendulum type (6 is the rotation axis of the pendulum) using a weight (5) of 800 g. The powder was uniformly attached to the rubber roller (1).
仮粉拭き工程、該仕上げ拭き工程は、図４に示すように、微細な隙間を有する布（１０）および布の内側に材質は、ウレタンでローラ状弾性体（１１）を配置した拭き部（１９）とした。ローラの円周方向に対して直角に押し当てる押し当て機構として、図５に示すように、拭き移動軸（１４）を中心に重り（１８）によりゴムローラに押し当てる方式を行った。また、拭き部のゴムローラと接触する円周方向に対して直角の長さは、８０ｍｍとした。また、ゴムローラと拭き部を離すのは、拭き部移動シリンダ（１７）を用いた。拭き部をゴムローラの円周方向に対して平行に、スライドさせるスライド機構としては、ロボット（２０）を使用し、拭き部を１０００ｍｍ／ｓｅｃの速度でゴムローラ端面から５０ｍｍ左右にオーバーランさせた（図６参照）。仮粉拭き終了時に、布クランプ送り（１５）にて布を固定し、布クランプ送り（１５）を移動させ、布巻き取り（１３）にて布を巻き取り所定の巻き取り終了後に、布固定クランプ（１２）および布送りクランプ（１５）を移動させた後に戻し再び布送りクランプ（１５）を固定することにより、布送りを行った。 As shown in FIG. 4, the temporary powder wiping step and the finish wiping step include a cloth (10) having fine gaps and a wiping portion in which the material is urethane and a roller-like elastic body (11) is arranged inside the cloth ( 19). As a pressing mechanism that presses at a right angle to the circumferential direction of the roller, as shown in FIG. 5, a method of pressing the rubber roller with a weight (18) around the wiping movement shaft (14) was performed. The length perpendicular to the circumferential direction in contact with the rubber roller of the wiping portion was 80 mm. Moreover, the wiping part moving cylinder (17) was used to separate the rubber roller from the wiping part. A robot (20) was used as a slide mechanism for sliding the wiping part parallel to the circumferential direction of the rubber roller, and the wiping part was overrun from the end face of the rubber roller to the left and right by 50 mm at a speed of 1000 mm / sec (see FIG. 6). At the end of temporary powder wiping, the cloth is fixed with the cloth clamp feed (15), the cloth clamp feed (15) is moved, and the cloth is wound with the cloth take-up (13). The cloth feed was performed by moving the clamp (12) and the cloth feed clamp (15) and then fixing the cloth feed clamp (15) again.
