Description

例えば、プラスチック製品の生産に使用される押出成形装置において、その機械構成部品である押出成形型やスクリュー等に付着、硬化したプラスチック等の付着物質の除去洗浄は、従来、ワイヤーブラシ等の用具を用いて掻き取り除去したり、あるいは予めバーナー等で燃焼炭化させた後にワイヤーブラシ等の用具を用いて掻き取り除去するなどの方法がとられていた。   For example, in an extrusion molding apparatus used for the production of plastic products, conventionally, tools such as wire brushes have been used for removing and cleaning adhered substances such as plastics that have adhered and hardened to extrusion molds and screws that are machine components. Such methods as scraping and removing using a brush or scraping and removing using a tool such as a wire brush after burning and carbonizing with a burner or the like have been used.

本発明によれば、洗浄液体に無数の微小洗浄粒体を混合してなる洗浄液剤に機械構成部品等の被洗浄物を浸漬して、これら洗浄液剤と被洗浄物に相対的な運動を与え、これにより、上記被洗浄物表面に対する洗浄液剤の擦れ合い作用および衝突作用を利用して、上記被洗浄物表面に付着硬化したプラスチック等の付着物質を磨耗粉砕して剥離除去するようにしたから、きわめて効率良く、しかも被洗浄物表面を傷付けることもなく、高い洗浄能力をもって剥離除去することができる。   According to the present invention, an object to be cleaned such as a machine component is immersed in a cleaning liquid obtained by mixing countless fine cleaning particles in a cleaning liquid, and a relative motion is given to the cleaning liquid and the object to be cleaned. Because of this, by using the rubbing action and collision action of the cleaning liquid with respect to the surface of the object to be cleaned, the adhering substances such as plastic that has adhered and hardened to the surface of the object to be cleaned are worn and pulverized and removed. It can be peeled and removed with a high cleaning ability with extremely high efficiency and without damaging the surface of the object to be cleaned.

すなわち、上記洗浄液剤に含まれる無数の微小洗浄粒体が被洗浄物と擦れ合い、あるいは被洗浄物に衝突することにより、被洗浄物表面に付着硬化した付着物質がこれら微小洗浄粒体により磨耗され、さらには粉砕されて、被洗浄物表面から剥離除去されることになる。   That is, the innumerable fine cleaning particles contained in the cleaning liquid rub against the object to be cleaned or collide with the object to be cleaned, so that the adhering substance adhered and hardened on the surface of the object to be cleaned is worn by these fine cleaning particles. Then, it is pulverized and peeled off from the surface of the object to be cleaned.

この場合、洗浄液剤の洗浄液体は、微小洗浄粒体の円滑な流動を促して、微小洗浄粒体の被洗浄物に対する擦れ合い作用および衝突作用を高めるとともに、付着物質が剥離除去された被洗浄物表面を磨き洗浄する作用もなす。   In this case, the cleaning liquid of the cleaning liquid promotes the smooth flow of the micro-cleaning particles to enhance the rubbing action and collision action of the micro-cleaning particles with respect to the object to be cleaned, and the object to be cleaned from which the adhered substances are peeled and removed. It also works to polish and clean the surface of objects.

さらに、上記洗浄液剤と被洗浄物を充填収容した洗浄槽を所定の動作パターンをもって動作させることで、とりわけ、上記洗浄槽を筒型容器の形態として、その軸線が垂直な公転軸に対して傾斜した状態で設けて、この洗浄槽を、上記公転軸まわりに公転させるとともに、この公転速度よりも大幅に減速されたゆっくりした所定の自転速度で垂直軸まわりに自転または停止させる。これにより、上記洗浄槽の公転により生じる遠心力が有効かつ十分に発揮されて、微小洗浄粒体と被洗浄物には、単なる水平方向の動きに止まらず、さらに洗浄槽の傾きによる傾斜内面との協働作用による上下方向の動きも誘発される。   Furthermore, by operating the cleaning tank filled with the cleaning liquid and the object to be cleaned with a predetermined operation pattern, in particular, the cleaning tank is in the form of a cylindrical container, and its axis is inclined with respect to the vertical revolution axis. In this state, the cleaning tank is revolved around the revolution axis, and is rotated or stopped around the vertical axis at a slow predetermined rotation speed that is significantly reduced than the revolution speed. As a result, the centrifugal force generated by the revolution of the cleaning tank is effectively and sufficiently exhibited, and the fine cleaning particles and the object to be cleaned are not limited to mere horizontal movements, and the inclined inner surface due to the inclination of the cleaning tank Up and down movement is also induced by the cooperative action.

その結果、微小洗浄粒体と被洗浄物は、洗浄槽内を上下左右方向へ流動（３次元相対運動）して、微小洗浄粒体が被洗浄物に対し効率よく擦れ合ったり衝突して、被洗浄物表面は上記微小洗浄粒体により高い研磨能力をもって研磨され、これにより、被洗浄物表面の付着物質は効率よく磨耗粉砕されて、被洗浄物表面から剥離除去される。   As a result, the micro cleaning particles and the object to be cleaned flow vertically and horizontally in the cleaning tank (three-dimensional relative motion), and the micro cleaning particles efficiently rub against or collide with the object to be cleaned. The surface of the object to be cleaned is polished with a high polishing ability by the fine cleaning particles, whereby the adhered substance on the surface of the object to be cleaned is efficiently abraded and removed from the surface of the object to be cleaned.

つまり、このような被洗浄物と微小洗浄粒体の３次元相対運動の実現により、洗浄槽の自転により生じる遠心力が、洗浄槽の公転により生じる遠心力を相殺することなく最大限度有効に発揮させて、円滑な３次元相対運動を確保することができる。   In other words, by realizing such a three-dimensional relative movement between the object to be cleaned and the fine cleaning particles, the centrifugal force generated by the rotation of the cleaning tank is effectively displayed to the maximum extent without offsetting the centrifugal force generated by the revolution of the cleaning tank. Thus, a smooth three-dimensional relative motion can be ensured.

また、洗浄槽を上記公転速度の−１／２０〜１／２０という非常にゆっくりした自転速度で自転させることにより、洗浄槽の隅部に存在する微小洗浄粒体被洗浄物にも上記洗浄槽の公転による遠心力が有効に作用して、洗浄槽内のすべての微小洗浄粒体と被洗浄物が円滑な３次元相対運動を行い、被洗浄物表面が高い洗浄能力をもって均一に洗浄され得る。   In addition, by rotating the cleaning tank at a very slow rotation speed of −1/20 to 1/20 of the revolution speed, the cleaning tank can be applied to the object to be cleaned of fine cleaning particles present in the corner of the cleaning tank. Centrifugal force due to the revolution of the surface effectively acts, and all the micro-cleaning particles in the cleaning tank and the object to be cleaned perform a smooth three-dimensional relative motion, and the surface of the object to be cleaned can be uniformly cleaned with a high cleaning ability. .

さらに、本発明の洗浄装置においては、上記効果に加えて、水平回転される回転テーブル上に、回転支軸が回転可能に支持されるとともに、この回転支軸に洗浄槽が回転テーブルの回転主軸に対して傾斜した状態で取り付けられ、上記回転テーブルの水平回転により、上記洗浄槽が上記回転主軸まわりに所定の速度をもって公転されるとともに、上記回転支軸まわりに自転する構成とされ、この洗浄槽を自転させる回転支軸の自転駆動が、上記回転主軸と同心状に設けられた太陽歯車と、上記回転支軸に同心状に設けられた遊星歯車とを含んでなる遊星歯車機構により行われる構成とされていることにより、洗浄槽の公転運動と自転運動が単一駆動源により行われて、装置構造が簡単かつコンパクトで、メンテナンスも容易に行うことができる。   Further, in the cleaning apparatus of the present invention, in addition to the above-described effects, a rotating support shaft is rotatably supported on a horizontally rotating rotary table, and a cleaning tank is supported on the rotating spindle of the rotary table. The cleaning tank is revolved at a predetermined speed around the rotation spindle by the horizontal rotation of the rotary table, and is configured to rotate around the rotation support shaft. The rotation driving of the rotating spindle that rotates the tank is performed by a planetary gear mechanism that includes a sun gear provided concentrically with the rotating spindle and a planetary gear provided concentrically with the rotating spindle. With this configuration, the revolving motion and rotational motion of the cleaning tank are performed by a single drive source, the device structure is simple and compact, and maintenance can be easily performed. .

以下、本発明の実施形態を図面に基づいて詳細に説明する。なお、図面全体にわたって同一の符号は同一の構成部材または要素を示している。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Throughout the drawings, the same reference numeral indicates the same component or element.

本発明に係る洗浄装置が図１〜図４に示されており、この洗浄装置は、具体的には、機械構成部品等の被洗浄物Ｗの表面に付着硬化したプラスチック等の付着物質を剥離除去するためのものである。ここでは、被洗浄物Ｗとして、図５に示すような、プラスチック製品の生産に使用される押出成形装置の機械構成部品であるセグメントスクリューを例にとり、このセグメントスクリューＷの表面に付着、硬化したポリエチレン、ポリプロピレン等のプラスチックの付着物質Ｏを剥離除去する場合について説明する。   A cleaning apparatus according to the present invention is shown in FIGS. 1 to 4, and specifically, this cleaning apparatus removes adhered substances such as plastic that has adhered and hardened on the surface of an object to be cleaned W such as machine components.

It is configured.

In the state where the cleaning tank 1 is accommodated in the cleaning tank receiver 17, the cleaning tank 17 has an axis inclined at a predetermined angle α with respect to an axis (revolution axis) X of the rotating main shaft 5. It is configured.

上記洗浄槽１の軸線の傾斜角度αは、具体的には１０度〜３０度、望ましくは１２度〜２０度に設定され、図示の実施形態においては、１５度の傾斜角度αとされている。   The inclination angle α of the axis of the cleaning tank 1 is specifically set to 10 degrees to 30 degrees, preferably 12 degrees to 20 degrees, and in the illustrated embodiment, the inclination angle α is 15 degrees. .

このように傾斜角度αが設定されるのは、傾斜角度αが１０度よりも小さい場合、および３０度よりも大きい場合、洗浄槽１の内周傾斜面と後述する洗浄槽１の公転により生じる遠心力との協働作用が確実に得られず、しかも、傾斜角度αが３０度よりも大きいと、洗浄槽１の洗浄槽受け１７への取付時に、バレル層１内に充填収容した内容物（被洗浄物Ｗ＋洗浄液剤ＣＬ）が外部へこぼれてしまうという構造上の問題があるからである。   The inclination angle α is set in this manner when the inclination angle α is smaller than 10 degrees or larger than 30 degrees due to the revolution of the inner peripheral inclined surface of the cleaning tank 1 and the cleaning tank 1 described later. If the cooperative action with the centrifugal force cannot be reliably obtained and the inclination angle α is larger than 30 degrees, the contents filled and accommodated in the barrel layer 1 when the cleaning tank 1 is attached to the cleaning tank receiver 17 This is because there is a structural problem in that (the object to be cleaned W + the cleaning liquid CL) spills to the outside.

遊星歯車機構３は、前述したように洗浄槽１の自転手段を構成するもので、少なくとも、上記回転主軸５と同心状に設けられた太陽歯車２０と、上記回転支軸１５に同心状に設けられた遊星歯車２１とを含んでなり、具体的には、上記太陽歯車２０、上記遊星歯車２１、およびこれら太陽歯車２０および遊星歯車２１の間に噛合状態で介装される少なくとも一つの中間歯車２２とを備えてなる。中間歯車２２の配設数は、遊星歯車２１つまり洗浄槽１の自転方向と自転速度を考慮して設定される。図示の実施形態においては、太陽歯車２０と遊星歯車２１とが単一の中間歯車２２を介して駆動連結されて、遊星歯車２１つまり洗浄槽１が公転方向（回転テーブル２の回転方向）と逆方向へ自転する構成とされている。   The planetary gear mechanism 3 constitutes the rotation means of the washing tank 1 as described above, and is provided concentrically at least with the sun gear 20 provided concentrically with the rotation main shaft 5 and the rotation support shaft 15. Specifically, the sun gear 20, the planetary gear 21, and at least one intermediate gear interposed between the sun gear 20 and the planetary gear 21 in a meshed state. 22. The number of the intermediate gears 22 is set in consideration of the rotation direction and the rotation speed of the planetary gear 21, that is, the cleaning tank 1. In the illustrated embodiment, the sun gear 20 and the planetary gear 21 are drivingly connected via a single intermediate gear 22 so that the planetary gear 21, that is, the cleaning tank 1 is opposite to the revolution direction (the rotation direction of the rotary table 2). It is configured to rotate in the direction.

太陽歯車２０は、上記回転テーブル２の回転主軸５と同心状にかつ静止状に設けられており、具体的には、図２に示すように、軸受２５、２５を介して上記回転主軸５に相対回転可能に軸支されるとともに、図示しない回止め手段によって、その回転運動が静止固定されている。   The sun gear 20 is provided concentrically and stationaryly with the rotary main shaft 5 of the rotary table 2. Specifically, as shown in FIG. 2, the sun gear 20 is attached to the rotary main shaft 5 via bearings 25 and 25. The shaft is supported so as to be relatively rotatable, and its rotational motion is stationary and fixed by an anti-rotation means (not shown).

遊星歯車２１は、上記回転テーブル２に回転可能に軸支された上記回転支軸１５に同心状にかつ一体的に設けられており、具体的には、図２に示すように、回転テーブル２の下側に突出した上記回転支軸１５の下端部に、一体的に取付けられている。   The planetary gear 21 is provided concentrically and integrally with the rotary support shaft 15 that is rotatably supported on the rotary table 2. Specifically, as shown in FIG. It is integrally attached to the lower end portion of the rotating support shaft 15 protruding downward.

中間歯車２２は、太陽歯車２０および遊星歯車２１の間に噛合状態で介装されるもので、具体的には、図２に示すように、上記回転テーブル２の下側において、回転テーブル２に支持固定された回転支軸２６に、軸受２７、２７を介して回転可能に軸支されるとともに、上記太陽歯車２０および遊星歯車２１にそれぞれ噛合されている。   The intermediate gear 22 is interposed between the sun gear 20 and the planetary gear 21 in an engaged state. Specifically, as shown in FIG. 2, the intermediate gear 22 is arranged on the rotary table 2 below the rotary table 2. The rotary shaft 26 is supported and fixed so as to be rotatable via bearings 27, 27 and meshed with the sun gear 20 and the planetary gear 21.

そして、回転主軸５の回転により、回転テーブル２が一体的に水平回転すると、この回転テーブル２上に配置支持された４つの洗浄槽１、１、…は、上記回転主軸５まわりに所定の速度をもって公転されるとともに、この公転運動に伴う遊星歯車機構３の減速作用により、非常にゆっくりした自転速度をもって自転されまたは停止されることとなる。   When the rotary table 2 rotates horizontally as a result of the rotation of the rotary spindle 5, the four cleaning tanks 1, 1,... Arranged and supported on the rotary table 2 are moved at a predetermined speed around the rotary spindle 5. And the planetary gear mechanism 3 accompanying the revolution motion is rotated or stopped at a very slow rotation speed.

より具体的には、図３を参照して、回転テーブル２の回転（矢符Ｘ方向）により、この回転テーブル２上に配置支持された４つの洗浄槽１、１、…も回転（公転）するところ、これら洗浄槽１、１、…の回転支軸１５、１５、…には、上記遊星歯車機構３の遊星歯車２１がそれぞれ取付け固定されている。この遊星歯車機構３において、太陽歯車２０は上述のごとく静止固定されているから、これら両歯車２０、２１に噛合連結された中間歯車２２を介して、上記遊星歯車２１は太陽歯車２０のまわりをＸ方向へ公転しながら、この公転速度よりも大幅に減速されたゆっくりした自転速度をもって公転方向と逆方向へ自転または停止することになる。   More specifically, with reference to FIG. 3, the four washing tanks 1, 1,... Arranged and supported on the rotary table 2 are also rotated (revolved) by the rotation of the rotary table 2 (in the direction of the arrow X). However, the planetary gear 21 of the planetary gear mechanism 3 is fixedly attached to the rotation support shafts 15, 15,... Of the washing tanks 1, 1,. In the planetary gear mechanism 3, the sun gear 20 is stationary and fixed as described above. Therefore, the planetary gear 21 is rotated around the sun gear 20 through the intermediate gear 22 meshed with both the gears 20 and 21. While revolving in the X direction, the vehicle rotates or stops in a direction opposite to the revolving direction with a slow revolving speed that is significantly reduced from the revolving speed.

この場合、上記洗浄槽１の自転速度は、遊星歯車機構３を構成する太陽歯車２０、中間歯車２２および遊星歯車２１の歯車比により決定され、具体的には公転速度の−１／２０〜０に設定され、望ましくは−１／３０〜−１／４０に設定される。上記洗浄槽１の公転速度は、遠心力が有効に働くことを考慮して、１００〜３００回転／分に設定されており、したがって、洗浄槽１の自転速度は５回転〜１５回転／分に設定される。   In this case, the rotation speed of the washing tank 1 is determined by the gear ratio of the sun gear 20, the intermediate gear 22 and the planetary gear 21 constituting the planetary gear mechanism 3, and specifically, −1/20 to 0 of the revolution speed. It is preferably set to −1/30 to −1/40. The revolution speed of the cleaning tank 1 is set to 100 to 300 rotations / minute in consideration of the effective centrifugal force. Therefore, the rotation speed of the cleaning tank 1 is set to 5 rotations to 15 rotations / minute. Is set.

このように洗浄槽１の自転速度が上記公転速度よりも大幅に減速されたゆっくりした値に設定されるのは、洗浄槽１の公転により生じる遠心力の作用効果が有効に発揮されるようにするためである。すなわち、洗浄槽１の自転速度が公転速度の１／２０よりも大きいと、洗浄槽１の公転により洗浄液剤ＣＬと被洗浄物Ｗに生じる遠心力の作用効果が、洗浄槽１の自転によりこれら洗浄液剤ＣＬと被洗浄物Ｗに生じる遠心力の作用効果によって減小され、ないしは相殺されて十分に発揮されず、洗浄槽１内における洗浄液剤ＣＬと被洗浄物Ｗの活発な動きが得られず、一方、洗浄槽１の自転速度が公転速度の０〜１／２０の大きさにあると、洗浄槽１の公転により洗浄液剤ＣＬと被洗浄物Ｗに生じる遠心力の作用効果が十分に発揮されて、洗浄液剤ＣＬと被洗浄物Ｗの動きが、単なる水平方向の動きに止まらず、洗浄槽１の傾斜角度αによる傾斜内面との協働作用による上下方向の動きも誘発されるからであり（３次元相対運動）、この作用効果は、洗浄槽１の自転速度が公転速度の−１／３０〜−１／４０に設定されると、より大きな作用効果が得られる。   The reason why the rotation speed of the washing tank 1 is set to a slow value that is significantly reduced from the revolution speed is that the effect of centrifugal force generated by the revolution of the washing tank 1 is effectively exhibited. It is to do. That is, when the rotation speed of the cleaning tank 1 is larger than 1/20 of the revolution speed, the effect of the centrifugal force generated in the cleaning liquid CL and the object W to be cleaned by the rotation of the cleaning tank 1 is caused by the rotation of the cleaning tank 1. It is reduced or offset by the effect of the centrifugal force generated on the cleaning liquid CL and the object W to be cleaned, and is not fully exhibited, and the active movement of the cleaning liquid CL and the object W in the cleaning tank 1 is obtained. On the other hand, when the rotation speed of the cleaning tank 1 is 0 to 1/20 of the revolution speed, the effect of centrifugal force generated in the cleaning liquid CL and the article W to be cleaned by the revolution of the cleaning tank 1 is sufficiently obtained. As a result, the movement of the cleaning liquid CL and the article W to be cleaned is not limited to a mere horizontal movement, and a vertical movement is also induced by the cooperative action with the inclined inner surface by the inclination angle α of the cleaning tank 1. (3D relative motion) and this action Fruits, the rotation speed of the cleaning tank 1 is set to -1 / 30-1/40 of the revolution speed, a greater effect can be obtained.

また、洗浄槽１が公転のみで、自転しない場合（つまり自転速度０の場合）よりも、上記のように公転速度の１／２０以下の非常にゆっくりした自転速度をもって自転する方が、洗浄槽１内の隅部に存在する洗浄液剤ＣＬと被洗浄物Ｗにも上記洗浄槽１の公転による遠心力が有効に作用して、洗浄槽１内の洗浄液剤ＣＬと被洗浄物Ｗが円滑な３次元相対運動を行うことができる。   In addition, the cleaning tank 1 rotates at a very slow rotation speed of 1/20 or less of the revolution speed as described above, rather than the case where the cleaning tank 1 revolves only and does not rotate (that is, when the rotation speed is 0). Centrifugal force due to the revolution of the cleaning tank 1 is also effectively applied to the cleaning liquid CL and the object W to be cleaned present in the corners of the tank 1, so that the cleaning liquid CL and the object W to be cleaned in the cleaning tank 1 are smooth. Three-dimensional relative motion can be performed.

図示の実施形態においては、洗浄槽１の自転速度は公転速度の１／３６に設定されている。   In the illustrated embodiment, the rotation speed of the cleaning tank 1 is set to 1/36 of the revolution speed.

また、洗浄槽１内に被洗浄物Ｗと共に投入充填される洗浄液剤ＣＬは、洗浄液体Ｌに無数の微小洗浄粒体Ｇ、Ｇ、…が混合されてなる。   In addition, the cleaning liquid CL charged and filled in the cleaning tank 1 together with the object to be cleaned W is formed by mixing countless fine cleaning particles G, G,.

微小洗浄粒体Ｇ、Ｇ、…は、具体的には洗浄用研磨材としてのメディアであり、その材質、形状、寸法（粒径）などの諸条件は、対象となる被洗浄物Ｗの形状寸法および付着物質Ｏの特性等に応じて適宜設定される。   Specifically, the fine cleaning particles G, G,... Are media as cleaning abrasives, and various conditions such as the material, shape, and dimensions (particle size) are determined by the shape of the object to be cleaned W. It is appropriately set according to the dimensions and the characteristics of the adhered substance O.

図示の実施形態においては、一般市販のバレル研磨用のバレルメディア（研磨用砥粒媒体）が種類豊富で安価に入手しやすいことから好適に使用されている。例えば、図示の実施形態における被洗浄物Ｗであるセグメントスクリューの形状寸法が、直径４０ｍｍで長さ７０ｍｍである場合は、直径４．５ｍｍで長さ９ｍｍ程度のセラミック系の微小バレルメディアが選択使用される。   In the illustrated embodiment, general commercially available barrel media for barrel polishing (abrasive media for polishing) are preferably used because they are abundant and easily available at low cost. For example, when the shape dimension of the segment screw which is the object to be cleaned W in the illustrated embodiment is 40 mm in diameter and 70 mm in length, a ceramic-based micro barrel medium having a diameter of 4.5 mm and a length of about 9 mm is selectively used. Is done.

洗浄液体Ｌは、微小洗浄粒体Ｇ、Ｇ、…の円滑な流動を促して、微小洗浄粒体Ｇ、Ｇ、…の被洗浄物Ｗに対する擦れ合い作用および衝突作用を高めるとともに、付着物質Ｏが剥離除去された被洗浄物Ｗ表面を磨き洗浄する作用をなすものであり、具体的には水に洗浄用研磨助剤としてのコンパウンドが混合されてなる。   The cleaning liquid L promotes the smooth flow of the fine cleaning particles G, G,... To enhance the rubbing action and the collision action of the fine cleaning particles G, G,. This serves to polish and clean the surface of the article W to be separated and removed. Specifically, water is mixed with a compound as a polishing aid for cleaning.

洗浄液体Ｌに混合されるコンパウンドとしては、界面活性剤を主成分としてものが好適に使用され、具体的な組成は、被洗浄物Ｗの材質や、使用する微小洗浄粒体Ｇ、Ｇ、…の種類に応じて適宜設定される。   As the compound to be mixed with the cleaning liquid L, a compound mainly composed of a surfactant is preferably used, and the specific composition includes the material of the object W to be cleaned and the micro cleaning particles G, G,. It is set as appropriate according to the type of.

図示の実施形態においては、一般市販のバレル研磨用のコンパウンド（研磨補助剤）が種類豊富で安価に入手しやすいことから好適に使用されている。   In the illustrated embodiment, commercially available barrel polishing compounds (polishing aids) are preferably used because they are abundant and easily available at low cost.

しかして、以上のように構成された洗浄装置において、回転テーブル２上に自転可能に設けられた洗浄槽受け１７、１７、…に、被洗浄物Ｗと洗浄液剤ＣＬ（微小洗浄粒体Ｇ、Ｇ、…＋洗浄液体Ｌ＋水）が充填収容された洗浄槽１がそれぞれ収容保持された状態（洗浄液剤ＣＬに被洗浄物Ｗが浸漬された状態）で、回転テーブル２が回転駆動されると、洗浄槽１は所定の動作パターンをもって動作され、つまり、垂直な回転主軸（公転軸）５まわりに水平方向に公転されて、各洗浄槽１内の被洗浄物Ｗと洗浄液剤ＣＬに遠心力が与えられる。これにより、被洗浄物Ｗと洗浄液剤ＣＬは、自重の違いも有効に作用して、相対的な運動を与えられ、被洗浄物Ｗ表面に対する洗浄液剤ＣＬ中の微小洗浄粒体Ｇ、Ｇ、…の擦れ合い作用および衝突作用により、被洗浄物Ｗ表面に付着した付着物質Ｏが磨耗粉砕して剥離除去されることとなる。これにより、被洗浄物Ｗ表面に付着硬化した付着物質Ｏが、きわめて効率良く、しかも被洗浄物Ｗ表面を傷付けることもなく、高い洗浄能力をもって剥離除去することができる。   In the cleaning apparatus configured as described above, the object to be cleaned W and the cleaning liquid CL (fine cleaning particles G, G) are placed on the cleaning tank receivers 17, 17,. When the rotary table 2 is driven to rotate in a state where the cleaning tank 1 filled with G (... + Cleaning liquid L + water) is stored and held (a state where the cleaning object W is immersed in the cleaning liquid CL). The cleaning tank 1 is operated with a predetermined operation pattern, that is, is revolved horizontally around a vertical rotation main shaft (revolution axis) 5 and centrifugal force is applied to the object to be cleaned W and the cleaning liquid agent CL in each cleaning tank 1. Is given. Thereby, the to-be-cleaned object W and the cleaning liquid agent CL effectively act on the difference in their own weight, and are given a relative motion, so that the minute cleaning particles G, G, Due to the rubbing action and the collision action, the adhering substance O adhering to the surface of the object W to be cleaned is worn and pulverized and removed. As a result, the adhered substance O that adheres and hardens on the surface of the object to be cleaned W can be peeled and removed with high cleaning ability without any damage to the surface of the object to be cleaned W with high efficiency.

この場合、洗浄槽１、１、…は、その軸線を上記回転主軸（公転軸）５に対して傾斜した状態で回転支軸１５にそれぞれ取り付けられるとともに、上記公転運動に伴う遊星歯車機構３の減速自転作用により、非常にゆっくりした自転速度（図示の実施形態においては、公転速度の１／３６）をもって公転方向Ｘと逆方向へ自転される。   In this case, the washing tanks 1, 1,... Are respectively attached to the rotation support shaft 15 with the axis thereof being inclined with respect to the rotation main shaft (revolution shaft) 5, and the planetary gear mechanism 3 associated with the revolution motion is provided. Due to the decelerating rotation action, the rotation is performed in a direction opposite to the revolution direction X with a very slow rotation speed (in the illustrated embodiment, 1/36 of the revolution speed).

この結果、各洗浄槽１内に充填収容された被洗浄物Ｗと洗浄液剤ＣＬの挙動、特に微小洗浄粒体Ｇ、Ｇ、…の挙動は、図４に示すように、洗浄槽１の傾斜内面に当たってランダムに跳ね返り立体的に動き、微小洗浄粒体Ｇ、Ｇ、…は、矢符図示のごとく中央部へ向けて中へ中へと練り込まれるように流動する。   As a result, the behavior of the object to be cleaned W and the cleaning liquid CL filled in each cleaning tank 1, particularly the behavior of the micro-cleaning particles G, G,..., As shown in FIG. It strikes the inner surface and randomly bounces and moves three-dimensionally, and the fine cleaning particles G, G,... Flow so as to be kneaded inward toward the center as shown by the arrows.

このような挙動は、洗浄槽１の公転により生じる遠心力が、微小洗浄粒体Ｇ、Ｇ、…と被洗浄物Ｗに対して単なる水平方向の動きに止まらず、さらに洗浄槽１の傾きによる傾斜内面との協働作用による上下方向の動きも誘発し、洗浄槽１内を上下左右方向へ流動（３次元相対運動）すると考えられる。   Such a behavior is due to the fact that the centrifugal force generated by the revolution of the cleaning tank 1 does not stop in the horizontal direction with respect to the fine cleaning particles G, G,. It is considered that vertical movement due to the cooperative action with the inclined inner surface is also induced to flow in the cleaning tank 1 in the vertical and horizontal directions (three-dimensional relative motion).

その結果、微小洗浄粒体Ｇ、Ｇ、…が被洗浄物Ｗに対し効率よく擦れ合ったり衝突して、被洗浄物Ｗ表面は上記微小洗浄粒体Ｇ、Ｇ、…により高い研磨能力をもって研磨され、これにより、被洗浄物Ｗ表面の付着物質Ｏは効率よく磨耗粉砕されて、被洗浄物Ｗ表面から剥離除去される。   As a result, the fine cleaning particles G, G,... Efficiently rub against or collide with the object to be cleaned W, and the surface of the object to be cleaned W is polished with high polishing ability by the fine particles G, G,. Thus, the adhering substance O on the surface of the object to be cleaned W is efficiently abraded and pulverized and peeled off from the surface of the object to be cleaned W.

特に、上記洗浄槽１の自転速度を、その公転速度の−１／２０〜０（より望ましくは−１／３０〜−１／４０（本実施形態においては１／３６））という低速またはゼロに設定することにより、洗浄槽１の自転により生じる遠心力が、洗浄槽１の公転により生じる遠心力を相殺することなく最大限度有効に発揮させて、円滑な３次元相対運動を確保することができる。   In particular, the rotation speed of the cleaning tank 1 is set to a low speed or zero of −1/20 to 0 (more desirably −1/30 to −1/40 (1/36 in the present embodiment)) of the revolution speed. By setting, the centrifugal force generated by the rotation of the cleaning tank 1 can be effectively exhibited as much as possible without canceling the centrifugal force generated by the revolution of the cleaning tank 1, and a smooth three-dimensional relative motion can be ensured. .

また、洗浄槽１をこのように非常にゆっくりした自転速度で自転させることにより、洗浄槽１の隅部に存在する微小洗浄粒体Ｇ、Ｇ、…にも上記洗浄槽１の公転による遠心力が有効に作用して、洗浄槽１内のすべての微小洗浄粒体Ｇ、Ｇ、…と被洗浄物Ｗが円滑な３次元相対運動を行い、被洗浄物Ｗ表面が高い洗浄能力をもって均一に洗浄され得る。   Further, by rotating the cleaning tank 1 at such a very slow rotation speed, the centrifugal force due to the revolution of the cleaning tank 1 is also applied to the minute cleaning particles G, G,. Works effectively, and all the fine cleaning particles G, G,... In the cleaning tank 1 and the object to be cleaned W perform a smooth three-dimensional relative motion, and the surface of the object to be cleaned W is uniformly uniform with high cleaning ability. Can be washed.

さらに、本実施形態の洗浄装置においては、以上の効果に加えて、水平回転される回転テーブル２上に、回転支軸１５、１５、…が回転可能に支持されるとともに、これら回転支軸１５、１５、…に洗浄槽１が回転テーブル２の回転主軸５に対して傾斜した状態でそれぞれ取り付けられ、上記回転テーブル２の水平回転により、各洗浄槽１が回転主軸５まわりに所定の速度（本実施形態においては、１００〜３００回転／分）をもって公転されるとともに、上記回転支軸１５まわりに自転する構成とされ、この洗浄槽１を自転させる回転支軸１５の自転駆動が、上記回転主軸５と同心状に設けられた太陽歯車２０と、上記回転支軸１５に同心状に設けられた遊星歯車２１とを含んでなる遊星歯車機構３により行われる構成とされていることにより、各洗浄槽１の公転運動と自転運動が単一駆動源（ギヤードモータ）１０により行われて、装置構造が簡単かつコンパクトで、メンテナンスも容易に行うことができる。   Further, in the cleaning device of the present embodiment, in addition to the above effects, the rotation support shafts 15, 15,... Are rotatably supported on the rotary table 2 that is horizontally rotated. , 15,... Are attached in a state where the washing tank 1 is inclined with respect to the rotary spindle 5 of the rotary table 2, and the horizontal rotation of the rotary table 2 causes each washing tank 1 to move around the rotary spindle 5 at a predetermined speed ( In the present embodiment, the rotation is performed at 100 to 300 revolutions / minute) and the rotation is performed around the rotation support shaft 15, and the rotation drive of the rotation support shaft 15 that rotates the cleaning tank 1 is the rotation. It is configured to be performed by a planetary gear mechanism 3 including a sun gear 20 provided concentrically with the main shaft 5 and a planetary gear 21 provided concentrically with the rotation support shaft 15. Ri, rotation movement and revolution movement of the cleaning tank 1 is performed by a single driving source (geared motor) 10, a simple and compact apparatus structure, it can be easily performed maintenance.

なお、上述した実施形態はあくまでも本発明の好適な実施態様を示すものであって、本発明はこれに限定されることなく、その範囲内で種々の設計変更が可能である。   Note that the above-described embodiment is merely a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope thereof.

例えば、図示の実施形態の遊星歯車機構３においては、太陽歯車２０と遊星歯車２１とが単一の中間歯車２２を介して駆動連結されて、洗浄槽１が公転方向（回転テーブル２の回転方向）Ｘと逆方向へ自転する構成とされているところ、具体的には図示しないが、前述した公転速度と自転速度との関係を保持しつつ、上記太陽歯車２０と上記遊星歯車２１とが、二つの中間歯車２２、２２を介して駆動連結される構成とすることにより、洗浄槽１が上記公転方向Ｘと同一方向へ自転するようにしてもよい。   For example, in the planetary gear mechanism 3 of the illustrated embodiment, the sun gear 20 and the planetary gear 21 are drivingly connected via a single intermediate gear 22 so that the cleaning tank 1 is in the revolution direction (the rotation direction of the rotary table 2). ) Although it is configured to rotate in the direction opposite to X, specifically, although not shown, the sun gear 20 and the planetary gear 21 hold the relationship between the revolution speed and the rotation speed described above, The cleaning tank 1 may be rotated in the same direction as the revolution direction X by being configured to be driven and connected through the two intermediate gears 22 and 22.

また、被洗浄物Ｗ表面に付着硬化する付着物質Ｏによっては、例えばポリプロピレン（ＰＰ）は前述した洗浄方法によっては容易に剥離除去できない。このような難除去性の付着物質Ｏが付着した被洗浄物Ｗの洗浄にあっては、上記洗浄方法において、被洗浄物Ｗを洗浄液剤ＣＬに浸漬するに先立って、ガスコンロ等の加熱手段により予め加熱処理して、付着物質Ｏを焼いて炭化させることにより、容易に剥離除去することができる。   Further, depending on the adhering substance O that adheres and hardens on the surface of the object to be cleaned W, for example, polypropylene (PP) cannot be easily peeled and removed by the above-described cleaning method. In the cleaning of the object to be cleaned W to which such a difficult-to-removably attached substance O adheres, in the above-described cleaning method, before the object to be cleaned W is immersed in the cleaning liquid CL, a heating means such as a gas stove is used. By performing a heat treatment in advance and baking the adhering substance O and carbonizing it, it can be easily peeled and removed.

この目的のため、具体的には図示しないが、図示の洗浄装置に、被洗浄物Ｗを加熱処理する加熱手段（ガスコンロ、ガスオーブン等）を備える構成とすることも可能である。   For this purpose, although not specifically shown, the cleaning apparatus shown in the figure can be provided with a heating means (gas stove, gas oven, etc.) for heat-treating the object to be cleaned W.

さらに、図示の実施形態においては、プラスチック製品の生産に使用される押出成形装置の機械構成部品であるセグメントスクリューを例にとって説明したが、本発明は、ブレーカプレート、ノズル、ギヤポンプ等の他の構成部品の洗浄はもちろんのこと、押出成形装置以外の同種装置において、同様な付着物質が付着する機械構成部品の洗浄にも適用可能である。   Furthermore, in the illustrated embodiment, the segment screw which is a mechanical component of an extrusion molding apparatus used for the production of plastic products has been described as an example. However, the present invention is not limited to other configurations such as a breaker plate, a nozzle, and a gear pump. It can be applied not only to cleaning parts, but also to cleaning of machine components to which similar substances adhere in a similar apparatus other than an extrusion molding apparatus.
