Description

本発明は、ＥＰ灰、飛灰等を混練・加湿する混練機に関する。 The present invention relates to a kneader for kneading and humidifying EP ash, fly ash, and the like.

従来、飛灰等の固化処理としては、飛灰に固化剤を混合し加水して混練後水和反応により固化することが行われている。飛灰等の固化処理には、飛灰と固化剤例えばセメントとを混合した原料を加水して混練する混練機が用いられる。この混練機としては一方に原料の飛灰等とセメントの混合物を投入する入口、他方に混練された原料、すなわち混練物の取り出し用の出口を設けたトラフ中に横軸の平行な回転軸（第１の回転軸及び第２の回転軸）に夫々混練部材を設けたものが知られている。 Conventionally, as the solidification treatment of fly ash and the like, a solidifying agent is mixed with and added to fly ash and kneaded and then solidified by a hydration reaction. For the solidification treatment of fly ash or the like, a kneader for adding and kneading the raw material mixed with fly ash and a solidifying agent such as cement is used. As this kneading machine, a horizontal rotation axis (a horizontal axis in a trough provided with an inlet for charging a mixture of raw fly ash and cement and a kneaded material on one side, that is, an outlet for taking out the kneaded material, is provided on the other side. A kneading member provided on each of the first rotating shaft and the second rotating shaft is known.

上述の混練部材としては、軸方向同一位置において２本の回転軸に夫々に板状の木の葉パドルを軸方向に密接配列して固定したものと、木の葉パドルに加えて軸方向に隣接して回転軸の外周にねじ羽根を設けたものと、回転軸の半径方向にロッドパドルを設け、第１の回転軸に設けたロッドパネルと第２の回転軸に設けたロットパドルは軸方向において重ならないが密接するように配列したものとがある。 As the above kneading member, a plate-shaped tree leaf paddle is closely arranged in the axial direction and fixed to two rotating shafts at the same position in the axial direction, and in addition to the tree leaf paddle, it rotates adjacent to the axial direction. The rod paddle provided on the outer periphery of the shaft and the rod paddle provided in the radial direction of the rotating shaft, and the rod panel provided on the first rotating shaft and the lot paddle provided on the second rotating shaft do not overlap in the axial direction. Are arranged in close proximity.

上記木の葉パドル、ロッドパドルは何れも軸方向に回転軸を中心としてスパイラル状に配列されている。 The leaf paddles and rod paddles of the tree are both arranged in a spiral shape around the rotation axis in the axial direction.

第１の回転軸に固定した木の葉パドルと第２の回転軸に固定した軸方向で同一位置にある木の葉パドルとはそれらの外周が常に接触又は接近しており、且つ軸方向において隣接する木の葉パドルは重ねられているから、混練する作用が強く、相手パドルの各面を互にクリーニングする（セルフクリーニングという）という点ですぐれた混練部材である。 The leaf paddles of the tree fixed to the first rotating shaft and the leaf paddles of the tree located in the same position in the axial direction fixed to the second rotating shaft are always in contact or close to each other, and the leaf paddles adjacent to each other in the axial direction Since they are stacked, they have a strong kneading action, and are excellent kneading members in that they clean each side of the mating paddle (referred to as self-cleaning).

しかし乍、製作費用が高価である。そして、混練抵抗が大きく、負荷対策、磨耗対策を必要としている。木の葉パドルが磨耗して取り替える場合に混練機の上下２つ割のトラフの上側のトラフを外した後に、根本的には下側のトラフから木の葉パドル付の回転軸を取り出し、その後、回転軸から木の葉パドルを軸方向に抜き、補修した木の葉パドルまたは新品の木の葉パドルを再び取り付けるという作業が必要であり、保守に時間がかかると共に費用の問題がある。 However, the production cost is expensive. And kneading | mixing resistance is large and needs a load countermeasure and an abrasion countermeasure. When the leaf paddle is worn and replaced, after removing the upper trough of the upper and lower split trough of the kneader, basically remove the rotating shaft with the leaf paddle from the lower trough, and then from the rotating shaft The operation of pulling out the leaf paddle in the axial direction and reattaching the repaired leaf leaf paddle or a new leaf leaf paddle is necessary, which requires maintenance and costs.

ただし、軽微な木の葉パドルの損傷は上側のトラフを外した後は、トラフから木の葉パドル付の回転軸を取り外すことなく、盛金、研削等による修復も可能である。
実公昭６１―７０３７号公報特開平９−１０５７０号公報実用新案登録第１６５３１９９号実用新案登録第１６５３２００号 However, minor damage to the leaf paddle can be repaired by banking, grinding, etc. without removing the rotating shaft with the leaf paddle from the trough after the upper trough is removed.

The first invention according to the present application is driven at the same rotational speed in the same direction by an electric motor in a trough having a raw material inlet at one end and a kneaded material outlet kneaded at the other end. A plurality of kneading members in the axial direction on a spiral surface twisted in the same torsional direction around the centerline of the rotation axis on the rotation axis of two parallel horizontal axes,
The kneading member is provided so as to overlap the first rotating shaft and the second rotating shaft in the axial direction, and each kneading member is a first rotating shaft in the axial direction of the first rotating shaft and the second rotating shaft. And a second kneading member provided on the second rotating shaft and a first kneading member provided on the first rotating shaft provided at the same position on the second rotating shaft and at the same position in the axial direction. In the kneader in which the member has a phase difference of 90 degrees in the rotation direction of the rotation shaft ,
The kneading member protrudes on one side in the radial direction of each rotating shaft or on both sides across the diameter, and has a radial length around the first rotating shaft of the first kneading member and a second rotating shaft of the second kneading member. The length in the radial direction as the center is such that the sum of the lengths is greater than the inter-axis distance between the first and second rotating shafts, and the first and second kneading members do not interfere with each other during rotation. And the first kneading member has a length that does not interfere with the second rotating shaft, or the second kneading member has a length that does not interfere with the first rotating shaft,
The kneading member comes into contact with the rotation shaft at the base side within a half circumference of the rotation shaft, has a mounting flange having a mounting hole, a protrusion formed integrally with the mounting flange and having a protruding end in the radial direction of the rotation shaft, A wear-resistant alloy tip member integrally provided at the tip, and
The tip of the kneading member kneaded product together with the kneading member in contact with the major axis of the projecting end side of the trajectory in the trajectory draw the tip of the mating kneading member leaves paddle on the kneaded product of the kneading member in the case of a rotating movement A member is formed, and the mounting flange and the protrusion have an uneven contour in the locus, and the end surface of the kneading member in the axial direction of the rotating shaft is a flat surface and is in contact with or close to the adjacent kneading member. The kneading machine is characterized in that the kneading machine is fixed to the rotating shaft by a screw member that is inserted into the mounting hole and screwed into the rotating shaft.

本出願に係る第２の発明は各回転軸の軸方向で同一位置にある第１の混練部材と第２の混練部材は半径方向の長さが等しいことを特徴とする第１の発明に記載の混練機である。 The second invention according to the present application is characterized in that the first kneading member and the second kneading member in the same position in the axial direction of each rotating shaft have the same radial length. Kneading machine.

本出願に係る第３の発明は軸方向で同一位置にある第１、第２の混練部材が第１、第２の回転軸の中心を結ぶ線に対して夫々４５度の角度をなした際に接近して互に干渉しない長さを有することを特徴とする第２の発明に記載の混練機である。 According to a third aspect of the present application, when the first and second kneading members at the same position in the axial direction form an angle of 45 degrees with respect to a line connecting the centers of the first and second rotating shafts, respectively. The kneading machine according to the second invention is characterized in that the kneading machine has a length that does not interfere with each other.

本発明によれば、混練部材は請求項１に記載の構成としたことにより、軸方向の一個所における混練部材の先端が画く円は互いに相手の円を切って混練物に二度作用するので、混練部材回りの混練物が仮に混練部材と共に回転移動をするとすれば、この移動に伴なって画かれる混練物上に画かれる混練部材の先端の軌跡は木の葉車形となる。そして、隣接する混練部材は接触又は近接しているので、木の葉車形の内側にその構成部材が沿って設けられた混練部材の凹部の混練物は混練されないで固化状態となる。そこで、混練部材と固化状態の混練物を併せるとあたかも木の葉車のようになる。そこで、混練効果の大きい木の葉車とほぼ同等の混練効果がある。その上、ねじ部材の着脱という簡単な作業で混練部材を回転軸に着脱できる。 According to the present invention, since the kneading member has the configuration described in claim 1, the circle drawn at the tip of the kneading member at one axial position cuts the other circle and acts twice on the kneaded product. If the kneaded material around the kneading member is rotationally moved together with the kneading member, the locus of the tip of the kneading member drawn on the kneaded material drawn along with this movement becomes a leaf wheel shape. Since the adjacent kneading members are in contact or close to each other, the kneaded material in the recesses of the kneading member provided with the constituent members inside the foliage wheel shape is solidified without being kneaded. Therefore, when the kneading member and the solidified kneaded material are combined, it looks like a leaf wheel. Therefore, there is a kneading effect substantially equivalent to that of a wooden leaf wheel having a large kneading effect. In addition, the kneading member can be attached to and detached from the rotating shaft by a simple operation of attaching and detaching the screw member.

A plurality of kneading members 6 and 7 are similarly provided on the rotary shafts 4 and 5 in the axial direction around two parallel rotary shafts 4 and 5 which are driven by the same motor in the same direction and at the same rotational speed. ing. Further, screws 6A and 7A (7A is provided on the rotary shaft 5) are provided on the rotary shafts 4 and 5 from the lower side of the inlet 2a toward the outlet side. The screws 6A and 7A are kneading members that perform mixing and kneading although the feeding force is large. The rotating shafts 4 and 5 provided with these kneading members 6, 7, 6A and 7A are referred to as rotors 19 and 21, respectively.

トラフ２は上下二つ割りであって下部は一体のトラフ２Ａで、上部が下部のトラフ２Ａに水平部２ｅ（図７参照）で接して結合されている。上部のトラフ２Ｂは一体ではなく、図５に示すように継目２ｆで軸方向の入口部のトラフ２Ｂ１、出口部のトラフ２Ｂ２に長手方向を分割して結合されている。回転軸４，５は、トラフ２中を挿通してトラフ２の一部としてトラフ２の前後に固定されたブラケット１０ａ，１０ｂに装架した軸受９，１４により夫々支持されている。トラフ２を回転軸４，５が貫通する部分はグランドパッキンのような軸封部材８，１２で軸封されている。 The trough 2 is divided into upper and lower parts, the lower part is an integral trough 2A, and the upper part is connected to the lower trough 2A by a horizontal part 2e (see FIG. 7). The upper trough 2B is not integrated, but is joined to the trough 2B1 at the inlet portion in the axial direction and the trough 2B2 at the outlet portion by dividing the longitudinal direction at a joint 2f as shown in FIG. The rotary shafts 4 and 5 are supported by bearings 9 and 14 mounted on brackets 10 a and 10 b that are inserted through the trough 2 and are fixed to the front and rear of the trough 2 as a part of the trough 2. The portion where the rotary shafts 4 and 5 pass through the trough 2 is shaft sealed by shaft sealing members 8 and 12 such as gland packing.

入口部のトラフ２Ｂ１上面には原料の入口２ａが設けてある。この入口２ａから混合機で例えば飛灰とセメントを攪拌し混合された原料が投入される。入口２ａ側には、回転軸４，５に一対のスクリュー６Ａ，７Ａが固定されている。このスクリューは回転軸４，５に嵌入固定された筒とこの筒の外周に同ピッチの一体にねじ羽根を設けたものであり、両スクリュー６Ａ，７Ａのねじ羽根は対向する位置で山と谷が係合している。 A raw material inlet 2a is provided on the upper surface of the trough 2B1 at the inlet. For example, fly ash and cement are stirred and mixed from the inlet 2a with a mixer. A pair of screws 6A and 7A are fixed to the rotary shafts 4 and 5 on the inlet 2a side. This screw has a cylinder fitted and fixed to the rotary shafts 4 and 5 and a screw blade integrally provided on the outer periphery of this cylinder with the same pitch. The screw blades of both screws 6A and 7A are crests and valleys at positions facing each other. Are engaged.

トラフ２の出口側の下面には混練物の出口２ｂが設けてある。この出口側にはスクリュー６Ａ，７Ａに続いて、回転軸４，５に夫々混練部材６，７群が固定されている。混練部材６，７は軸方向同位置のものは互いに接するか、接近している。混練部材６，７の先端とトラフ２の内壁面はすきま少く接近している。混練部材６，７は軸方向で隣る混練部材６，７とは夫々について同一方向にリード角を附して捩って回転軸４，５に固定されており、混練部材６，７群は全体としてリードを附されており、混練作用と共に送り機能を持っている。 An outlet 2b for the kneaded material is provided on the lower surface of the trough 2 on the outlet side. On the outlet side, the kneading members 6 and 7 are fixed to the rotary shafts 4 and 5, respectively, following the screws 6A and 7A. The kneading members 6 and 7 in the same axial direction are in contact with each other or close to each other. The tips of the kneading members 6 and 7 and the inner wall surface of the trough 2 are close to each other with a small clearance. The kneading members 6 and 7 are fixed to the rotary shafts 4 and 5 by twisting them with the lead angle in the same direction as the kneading members 6 and 7 adjacent in the axial direction. The lead is attached as a whole, and it has a feeding function with kneading action.

出口２ｂはトラフ２の下面に設けた開口２ｂ１と開口２ｂ１の面積よりも断面積の大きい出口シユート２ｂ２を備えている。 The outlet 2b includes an opening 2b1 provided on the lower surface of the trough 2, and an outlet shout 2b2 having a larger cross-sectional area than the area of the opening 2b1.

上部のトラフ２Ｂには添加水ノズル１１が複数長手方向に配してある。このノズル１１は図示されない水源に配管されており、トラフ２内へ水を圧送するようになっている。 A plurality of additive water nozzles 11 are arranged in the longitudinal direction in the upper trough 2B. The nozzle 11 is piped to a water source (not shown) so as to pump water into the trough 2.

以上の混練機は前工程の混合機中に於いて飛灰等と固化剤のセメントが混合加水されて、その入口２ａに結合された混合機より原料として投入される。図示されない電動機から、動力伝達装置、軸継手４ｋ，５ｋを介して駆動されている回転軸４，５上のスクリュー６Ａ，７Ａ及び混練部材６，７は夫々は回転しており、スクリュー６Ａ，７Ａは互いにトラフ２の内壁と隙間少なく配されており、該内壁と外周を接してもしくは接近して回動して原料は混練される。又、スクリュー６Ａ，７Ａはリードがあるから原料は軸方向に送られる。スクリュー６Ａ，７Ａにより図５、図６において右方に送られた原料は混練される。即ち、混練部材６，７で夫々原料が練り合わされ、順次図５、図６において右方に送られて出口２ｂに到達する。上記入口側から出口側への原料の進行の過程で添加水ノズル１１により加水される。 In the kneader described above, fly ash and the cement of the solidifying agent are mixed and added in the mixer in the previous step, and the raw material is charged from the mixer connected to the inlet 2a. The screws 6A and 7A and the kneading members 6 and 7 on the rotary shafts 4 and 5 driven from the electric motor (not shown) through the power transmission device and the shaft couplings 4k and 5k are rotating, and the screws 6A and 7A. Are arranged with a small gap from the inner wall of the trough 2, and the raw material is kneaded by rotating while contacting or approaching the inner wall and the outer periphery. Since the screws 6A and 7A have leads, the raw material is fed in the axial direction. The raw materials sent to the right in FIGS. 5 and 6 are kneaded by the screws 6A and 7A. That is, the raw materials are kneaded by the kneading members 6 and 7, respectively, and sequentially sent to the right in FIGS. 5 and 6 to reach the outlet 2b. Water is added by the added water nozzle 11 in the course of the progress of the raw material from the inlet side to the outlet side.

かくして出口２ｂの出口開口２ｂ１上に到達した混練物は出口開口２ｂ１を通り落下する。この際、混練物は出口開口２ｂ１の内周に接するのみで出口シユート２ｂ２には付着しない。この出口開口２ｂ１の内周は混練物の移動方向には極めて短く、仮にこの部分に混練物が付着してもスクリュー６Ａ，７Ａ、混練部材６，７の推力による内部の混練物の圧力で剥離する。出口開口２ｂ１から出た混練物は図示されない成形機又は搬送コンベアへ供給される。 Thus, the kneaded material that has reached the outlet opening 2b1 of the outlet 2b falls through the outlet opening 2b1. At this time, the kneaded material only comes into contact with the inner periphery of the outlet opening 2b1, and does not adhere to the outlet shout 2b2. The inner periphery of the outlet opening 2b1 is very short in the moving direction of the kneaded material, and even if the kneaded material adheres to this portion, it is peeled off by the pressure of the internal kneaded material by the thrust of the screws 6A, 7A and the kneading members 6, 7. To do. The kneaded material exiting from the outlet opening 2b1 is supplied to a molding machine or a conveyor not shown.

And a mounting flange 15 having a mounting hole 15a, a projecting portion 16 formed integrally with the mounting flange 15 and having a projecting end 16a in the radial direction of the rotary shafts 4 and 5, and a projecting end 16a of the projecting portion 16 provided integrally. And a wear-resistant alloy tip member 17.

フランジ１５は回転軸４，５の外周に軸方向に沿うと共に周方向に沿っている。フランジ１５の軸方向の長さは短いので軸方向には全面で回転軸４，５の外周に接する。フランジ１５の形状は回転軸４，５の周方向に関しては、くら形となっている。即ち、回転軸４，５との接触部１５ｂに接触する平板状の交叉する回転軸４，５に面する部分を回転軸４，５の半径よりも小さい半径ｒで丸めてある。このフランジ１５と回転軸４，５との接触部１５ｂは図１に示すように六角ボルトのようなねじ部材１８の中心線１８ａ上にて接触する。この中心線１８ａは回転軸４，５の中心Ｃ４１，Ｃ５１から半径方向にのびる直線である。取付フランジ１５に設ける取付穴１５ａの中心は中心線１８ａと一致するようになっている。上記のように、フランジ１５をくら形としたことにより製作が容易で安定した形で回転軸４，５に着座できる。 The flange 15 extends along the outer circumference of the rotary shafts 4 and 5 along the circumferential direction and along the circumferential direction. Since the length of the flange 15 in the axial direction is short, the entire surface of the flange 15 is in contact with the outer periphery of the rotary shafts 4 and 5. The shape of the flange 15 is a square shape in the circumferential direction of the rotary shafts 4 and 5. That is, the flat-shaped intersecting rotary shafts 4 and 5 that are in contact with the contact portions 15 b with the rotary shafts 4 and 5 are rounded with a radius r smaller than the radius of the rotary shafts 4 and 5. A contact portion 15b between the flange 15 and the rotary shafts 4 and 5 contacts on a center line 18a of a screw member 18 such as a hexagon bolt as shown in FIG. The center line 18a is a straight line extending in the radial direction from the centers C41 and C51 of the rotary shafts 4 and 5. The center of the mounting hole 15a provided in the mounting flange 15 is made to coincide with the center line 18a. As described above, the flange 15 is shaped like a pillow so that it can be easily and stably seated on the rotary shafts 4 and 5.

フランジ１５の回転軸４，５の軸方向から見て中央には突出部１６が回転軸４，５の半径方向に突出している。突出部１６の半径方向の中心線１６ｃは、中心Ｃ４１，Ｃ５１（中心Ｃ４１は回転軸４の中心、中心Ｃ５１は回転軸５の中心）に張る中心線１８ａ，１８ａ間の角を２等分する線である。フランジ１５と突出部１６の根本は両者が一体となるように溶接してある。ｗ１は溶接部である。 A protrusion 16 projects in the radial direction of the rotary shafts 4 and 5 at the center when viewed from the axial direction of the rotary shafts 4 and 5 of the flange 15. The center line 16c in the radial direction of the protrusion 16 bisects the angle between the center lines 18a and 18a extending to the centers C41 and C51 (the center C41 is the center of the rotating shaft 4 and the center C51 is the center of the rotating shaft 5). Is a line. The bases of the flange 15 and the protrusion 16 are welded so that they are integrated. w1 is a welding part.

上記フランジ１５と突出部１６との軸方向の夫々の端面１５ｃ，１６ｂは共通の一平面上にある。この端面１５ｃ，１６ｂには端板２４，２４が当接して固定されている。端板２４，２４の形状は図１に示すように縁２４ａがフランジ１５の端面１５ｃに沿っている。そして、突出部１６の突出方向へ台形にのびた形状である。詳しくは、中心線１８ａに平行する縁２４ｂ、突出部１６の突出方向へ両側からせばまる斜設した縁２４ｃ、突出部１６の突出方向先端に近い縁２４ｄを有する形状である。端板２４、２４とフランジ１５、突出部１６の当接部分の隅は溶接されている。ｗ２がその溶接部である。回転軸４，５の軸方向で隣接する混練部材６，７が当接又は近接するのは端板２４の端面２４ｇである。この端面２４ｇは混練部材６，７の端面６ｆ，７ｆでもある。 The end surfaces 15c and 16b in the axial direction of the flange 15 and the protruding portion 16 are on a common plane. End plates 24 and 24 are fixed in contact with the end surfaces 15c and 16b. As shown in FIG. 1, the end plates 24 and 24 have an edge 24 a along the end surface 15 c of the flange 15. And it is the shape extended to the protrusion direction of the protrusion part 16 in the trapezoid. Specifically, it has a shape having an edge 24b parallel to the center line 18a, an oblique edge 24c that fits in the protruding direction of the protruding portion 16 from both sides, and an edge 24d that is close to the protruding end of the protruding portion 16 in the protruding direction. The corners of the contact portions of the end plates 24, 24, the flange 15, and the protrusion 16 are welded. w2 is the weld. The kneading members 6 and 7 adjacent in the axial direction of the rotary shafts 4 and 5 are in contact with or close to each other on the end surface 24g of the end plate 24. The end face 24g is also the end faces 6f and 7f of the kneading members 6 and 7.

先端部材１７は耐摩耗性合金、例えば、焼結合金、チタン被覆金属等であり、突出部１６と一体に焼結、又は溶着等により固着されている。先端部材１７の回転軸４，５の軸方向における幅は突出部１６の幅と同じである。 The tip member 17 is a wear-resistant alloy, for example, a sintered alloy, a titanium-coated metal, or the like, and is fixed integrally with the protrusion 16 by sintering or welding. The width of the tip member 17 in the axial direction of the rotation shafts 4 and 5 is the same as the width of the protrusion 16.

混練部材６，７の半径方向の突出長さＲは曲線ｖで形成される木の葉パドルの長径ａの半分以内の長さである。ただし回転軸４，５の中心Ｃ４１，Ｃ５１と点ｘ１間の長さにまで突出長さＲを大きくできる。曲線ｖ内で点ｘ１まで先端部材１７を設けても相手混練部材と干渉することがないように軸間距離を選択すればよいが、先端部が尖鋭であると急速に磨耗する。そこで先端部材１７の先端面１７ｄは予め図示のように点ｘ１より退けて丸めてある。そして、先端面１７ｄと舌部１７ａ，１７ｂとの角１７ｃは丸めた状態で曲線ｖと接している。角１７ｃによって木の葉パドルとなる曲線ｖが形成される。曲線ｖについて後述する作用の説明において説明する。 The protruding length R in the radial direction of the kneading members 6 and 7 is a length within half of the major axis a of the leaf paddle formed by the curve v. However, the protruding length R can be increased to the length between the centers C41 and C51 of the rotary shafts 4 and 5 and the point x1. Even if the tip member 17 is provided up to the point x1 in the curve v, the distance between the axes may be selected so as not to interfere with the mating member, but if the tip portion is sharp, it is worn rapidly. Therefore, the distal end surface 17d of the distal end member 17 is previously rounded away from the point x1 as shown in the figure. The corner 17c between the tip surface 17d and the tongues 17a and 17b is in contact with the curve v in a rounded state. A curve v serving as a leaf paddle is formed by the corner 17c. The curve v will be described in the description of the action described later.

上述のように構成された混練部材６，７は回転軸４，５に取付フランジ１５を当接して、取付穴１５ａを挿通してねじ部材１８例えば六角ボルトを回転軸４，５に設けた半径方向のめねじにねじ込む。 The kneading members 6 and 7 configured as described above have the mounting flange 15 abutted against the rotating shafts 4 and 5, and are inserted through the mounting holes 15 a so that the screw members 18, for example, hexagon bolts are provided on the rotating shafts 4 and 5. Screw in the female screw in the direction.

上述より明らかなように、この混練部材６，７はトラフ２Ｂを取り外して開放すると、外部に露出する。そこで、ボックススパナを用いてねじ部材１８を弛めることも締めることもできるので、トラフ２からロータ１９，２１を取り外すことなく、回転軸４，５に混練部材６，７の取付け、取外しができる。 As apparent from the above, the kneading members 6 and 7 are exposed to the outside when the trough 2B is removed and opened. Therefore, since the screw member 18 can be loosened or tightened using a box spanner, the kneading members 6 and 7 can be attached to and detached from the rotary shafts 4 and 5 without removing the rotors 19 and 21 from the trough 2.

混練部材６，７は夫々回転軸４，５の軸方向において同一位置において９０度位相を異にして設けられる。また、混練部材６，７は回転軸４，５の直径をわたる両側へ突出して設けられる。また、混練部材６，７は多数を有し、夫々の混練部材６，７は回転軸４，５の軸方向で接触して隣接又は隣り合って接近している。また、各回転軸４，５上において、この回転軸４，５を中心としてスパイラル状に混練部材６，７は配設されている。混練部材６，７は回転軸の直径をわたる両側へ突出しているので、上記スパイラルは２重のスパイラルである。 The kneading members 6 and 7 are provided with a phase difference of 90 degrees at the same position in the axial direction of the rotary shafts 4 and 5, respectively. The kneading members 6 and 7 are provided so as to protrude to both sides across the diameter of the rotary shafts 4 and 5. The kneading members 6 and 7 have a large number, and the kneading members 6 and 7 are in contact with each other in the axial direction of the rotating shafts 4 and 5 and are adjacent or adjacent to each other. In addition, the kneading members 6 and 7 are arranged in a spiral shape around the rotary shafts 4 and 5 on the rotary shafts 4 and 5. Since the kneading members 6 and 7 protrude to both sides over the diameter of the rotating shaft, the spiral is a double spiral.

図２５は２重のスパイラルの場合の回転軸４上の混練部材６を回転軸４の軸方向から見る正面図である。図において、混練部材６は図２５では手前側より奥側へ右回りに、図２６では左側から右側へ符号６ａ−１から６ａ−４へ、６ｂ−１から６ｂ−４右方向へねじれ乍ら軸方向に位置を変えている。ここで６ａ−ｉと６ｂ−ｉ（ｉ：１…４）とは回転軸４の軸方向の同一位置において直径をわたる両側へ突出している。回転軸５上の混練部材７についても同様に表現される。 FIG. 25 is a front view of the kneading member 6 on the rotary shaft 4 viewed from the axial direction of the rotary shaft 4 in the case of a double spiral. In FIG. 25, the kneading member 6 is twisted clockwise from the near side to the far side in FIG. 25, from left to right in FIG. 26 from 6a-1 to 6a-4, and from 6b-1 to 6b-4 in the right direction. The position is changed in the axial direction. Here, 6a-i and 6b-i (i: 1... 4) protrude to both sides across the diameter at the same position in the axial direction of the rotating shaft 4. The kneading member 7 on the rotating shaft 5 is similarly expressed.

図２６はロータを平面に展開して見る展開図である。図２６は回転軸を基準に展開してある。 FIG. 26 is a development view in which the rotor is developed on a plane. FIG. 26 is developed based on the rotation axis.

次に混練部材６，７の輪郭には範囲があることを説明する。図１に示すように混練部材６，７は曲線ｖ，ｖで囲まれた範囲内に設ける必要がある。その理由を以下にのべる。 Next, it will be described that the contours of the kneading members 6 and 7 have a range. As shown in FIG. 1, it is necessary to provide the kneading members 6 and 7 within the range surrounded by the curves v and v. The reason is as follows.

今、混練部材６ａ，６ｂが回転するときの混練部材６ａ，６ｂの先端が画く円内の混練部材６の軌跡内では混練物は混練部材６ａ，６ｂと共に回転するものとする。同様に混練部材７ａ，７ｂが回転するときの混練部材７ａ，７ｂの先端が画く円内の混練部材７の軌跡内では混練物は混練部材７ａ，７ｂと共に回転するものとする。 Now, it is assumed that the kneaded material rotates together with the kneading members 6a and 6b in the locus of the kneading member 6 in the circle where the tips of the kneading members 6a and 6b rotate when the kneading members 6a and 6b rotate. Similarly, it is assumed that the kneaded material rotates together with the kneading members 7a and 7b in the locus of the kneading member 7 in a circle where the tips of the kneading members 7a and 7b rotate when the kneading members 7a and 7b rotate.

そして、混練部材６ａ，６ｂの先端が画く円内の混練物を混練部材７ａ，７ｂが攪拌して移動する際に混練部材６ａ，６ｂの回転と共に回転する混練物に混練部材７ａ，７ｂの先端が画く軌跡を考える。同様に混練部材７ａ，７ｂの先端が画く円内の混練物を混練部材６ａ，６ｂが攪拌して移動する際に混練部材７ａ，７ｂの回転と共に回転する混練部材６ａ，６ｂの先端が画く軌跡を考える。 Then, when the kneading members 7a and 7b move while stirring and moving the kneaded material in a circle in which the tips of the kneading members 6a and 6b are drawn, the tips of the kneading members 7a and 7b rotate with the rotation of the kneading members 6a and 6b. Think about the trajectory of the image. Similarly, when the kneading members 6a and 6b move while stirring the kneaded material in a circle in which the tips of the kneading members 7a and 7b are drawn, the locus of the tips of the kneading members 6a and 6b rotating with the rotation of the kneading members 7a and 7b is drawn. think of.

図８から図２４を用いて上記構成の作用をのべる。図８から図２４では混練部材６，７は模式的に画かれている。図示されない電動機が付勢されると軸継手４ｋ，５ｋが回転する。そこで回転軸４，５は同方向に等速で回転する。即ち、ロータ１９，２１は図示矢印イ、ロの方向に等速回転する。 The operation of the above configuration will be described with reference to FIGS. 8 to 24, the kneading members 6 and 7 are schematically depicted. When a motor (not shown) is energized, the shaft couplings 4k and 5k rotate. Therefore, the rotary shafts 4 and 5 rotate at the same speed in the same direction. That is, the rotors 19 and 21 rotate at a constant speed in the directions of the arrows a and b shown in the figure.

混練部材６，７の軸方向の１個所における作用についてのべる。この混練部材６，７の前後の位置においてはトラフ２中に混練中の原料が充満しているとする。 The action of the kneading members 6 and 7 at one place in the axial direction will be described. It is assumed that the raw material being kneaded is filled in the trough 2 at positions before and after the kneading members 6 and 7.

図８から図２４までは混練部材６，７が１回転する際の作用が示されている。ここで、混練部材６の回転軸４の直径をわたる両側に夫々反対方向に突出する部分を混練部材６ａ，６ｂ、混練部材７の回転軸５の直径をわたる両側に夫々反対方向に突出する部分を混練部材７ａ，７ｂとする。 8 to 24 show the operation when the kneading members 6 and 7 rotate once. Here, the portions of the kneading member 6 that protrude in opposite directions on both sides across the diameter of the rotating shaft 4 are the portions that protrude in the opposite direction on both sides of the kneading members 6a and 6b and the diameter of the rotating shaft 5 of the kneading member 7 respectively. Are kneading members 7a and 7b.

図８に示すように、混練部材６ａ，６ｂが回転軸４，５を結ぶ線ＣＬ及びその延長線上に有って、混練部材６ｂが回転軸５の方を向いている位置及び混練部材７ａ，７ｂが回転軸５，４を結ぶ線ＣＬに直角方向の線上にあって、混練部材７ｂが上方を向いている位置を０（ゼロ）回転の位置（以下、単に０（ゼロ）位置という）とする。 As shown in FIG. 8, the kneading members 6a and 6b are on the line CL connecting the rotary shafts 4 and 5 and the extension line thereof, and the kneading member 6b is facing the rotary shaft 5 and the kneading members 7a, A position where 7b is on a line perpendicular to the line CL connecting the rotation shafts 5 and 4 and the kneading member 7b faces upward is a 0 (zero) rotation position (hereinafter simply referred to as a 0 (zero) position). To do.

図８から図２４までロータ１９，２１は連続して１回転する。図８から図２４の各図は夫々１回転中の回転角２２．５度毎の混練部材６ａ，６ｂ，７ａ，７ｂの位置を示してある。 8 to 24, the rotors 19 and 21 continuously rotate once. 8 to 24 show the positions of the kneading members 6a, 6b, 7a, and 7b at every rotation angle of 22.5 degrees during one rotation.

図８から図９に示すようにロータ１９，２１が０（ゼロ）位置から矢印イ、ロの方向に夫々２２．５度回転すると、各混練部材６ａ，６ｂ，７ａ，７ｂの回転方向の前面の混練物を押す。各混練部材６ａ，６ｂ，７ａ，７ｂの回転方向の後方には各混練部材６ａ，６ｂ，７ａ，７ｂの移動の軌跡として空間ができることになるがこの空間には混練物が送り込まれる。この移動の軌跡としての空間への送り込みは各混練部材６ａ，６ｂ，７ａ，７ｂの移動方向の前面からの一部回り込みと、次に述べる軸方向からの移動による送り込みである。 As shown in FIGS. 8 to 9, when the rotors 19 and 21 are rotated 22.5 degrees from the 0 (zero) position in the directions of arrows a and b, respectively, the front surfaces of the kneading members 6a, 6b, 7a, and 7b in the rotational direction. Press the kneaded product. The kneading members 6a, 6b, 7a, and 7b have a space behind the rotational direction of the kneading members 6a, 6b, 7a, and 7b. A kneaded material is fed into this space. This feeding to the space as a locus of movement is a part of the kneading members 6a, 6b, 7a and 7b from the front in the moving direction and a feed by movement from the axial direction described below.

混練物はロータ１９では各混練部材６ａが回転軸４を中心とする右ねじれの２重のスパイラル面上にある。及びロータ２１では各混練部材が回転軸５を中心とする右ねじれの２重のスパイラル面上にある。そこで、混練部材６ａ，７ａ群は図５，図６において混練物を左方から右方へ送る作用を有する。従って、混練部材６ａ，６ｂの夫々の位置において混練物は軸方向の送り力を受けている。 In the rotor 19, each kneading member 6 a is on a double spiral surface having a right-handed twist about the rotation shaft 4. And in the rotor 21, each kneading member exists on the double spiral surface of the right twist centering on the rotating shaft 5. FIG. Therefore, the kneading members 6a and 7a have the function of sending the kneaded material from left to right in FIGS. Therefore, the kneaded material receives an axial feeding force at each position of the kneading members 6a and 6b.

図９に示すようにロータ１９，２１が０位置から２２．５度回転すると、０位置よりも以前から回転した混練部材７ｂの先端が画いた円弧ｃ内の混練部材７ｂの軌跡中の混練物の一部は重ねて混練部材６ｂによって混練されている。そして、混練部材６ｂ先端が円弧ｃの外側へ出るまでに曲線ｄが混練部材７ｂにより混練物が一度だけ混練される領域ｅと一度混練された混練物の一部が二度混練される領域ｆの境となる。ここで曲線ｄは、混練部材７ａ，７ｂと共に円弧ｃ内の混練物が回転移動するとしたら（以下、同様に考える）混練部材６ｂの先端が該混練物中に画く軌跡である。詳しくは、領域ｆでは混練部材７ｂの移動により、混練部材７ｂの移動方向の前方から後方に回り込んだ混練物が２回目の混練を受け軸方向に送られてくる混練物が初めての混練を受ける。 As shown in FIG. 9, when the rotors 19 and 21 are rotated 22.5 degrees from the 0 position, the kneaded material in the locus of the kneading member 7b in the arc c in which the tip of the kneading member 7b rotated from before the 0 position is drawn. A part of these are overlapped and kneaded by the kneading member 6b. Then, until the tip of the kneading member 6b comes out of the arc c, a curve d indicates a region e where the kneaded material is kneaded only once by the kneading member 7b and a region f where a part of the kneaded material once kneaded is kneaded twice. The border. Here, the curve d is a trajectory in which the tip of the kneading member 6b is drawn in the kneaded material when the kneaded material in the arc c rotates and moves together with the kneading members 7a and 7b (hereinafter, similarly). Specifically, in the region f, the kneaded material that has been moved from the front to the rear in the moving direction of the kneading member 7b by the movement of the kneading member 7b undergoes the second kneading, and the kneaded material that is sent in the axial direction performs the first kneading. receive.

図１０を参照して、混練部材６ｂは混練部材７ｂの軌跡である円弧ｃ内から円弧ｃ外へ出る。そして、混練部材７ａはその先端が混練部材６ｂの先端が画いた円弧ｇに接近する。 Referring to FIG. 10, kneading member 6b goes out of arc c from the inside of arc c, which is the locus of kneading member 7b. And the kneading member 7a approaches the arc g where the tip of the kneading member 6b is drawn.

図１０に示すようにロータ１９，２１が０位置から４５度回転すると混練部材６ｂと７ａは長さが等しく、先端が接近する。このとき、回転軸４，５の中心を結ぶ線ＣＬに対して混練部材６ｂ，７ａは共に４５度をなしている。混練部材６ｂと７ａの先端が互いに干渉しないように混練部材６ｂと７ａの先端間に回転軸４，５の中心を結ぶ線ＣＬ方向で隙間ｔを設けてある。続くロータ１９，２１の回転により、混練部材６ｂの移動の軌跡ｉ上には混練部材７ａが混練部材７ａの前進側の混練物を押し出すと共に入口２ａ側から出口２ｂ側方向の軸方向から送られる混練物が進入する。 As shown in FIG. 10, when the rotors 19 and 21 are rotated 45 degrees from the 0 position, the kneading members 6b and 7a are equal in length and the tips approach each other. At this time, the kneading members 6b and 7a are both 45 degrees with respect to the line CL connecting the centers of the rotary shafts 4 and 5. A gap t is provided in the direction of line CL connecting the centers of the rotary shafts 4 and 5 between the tips of the kneading members 6b and 7a so that the tips of the kneading members 6b and 7a do not interfere with each other. By the subsequent rotation of the rotors 19 and 21, the kneading member 7a pushes the kneaded material on the advancing side of the kneading member 7a onto the trajectory i of the kneading member 6b and sends it from the inlet 2a side to the outlet 2b side in the axial direction. The kneaded material enters.

図１１を参照して、図１０の位置から、ロータ１９，２１がわずかに回転すると、混練部材６ｂの先端の移動の軌跡の回転軸４の中心を中心とする円弧ｇ上の点ｈに混練部材７ａの先端がくる。 Referring to FIG. 11, when the rotors 19 and 21 are slightly rotated from the position of FIG. 10, the kneading is performed at a point h on the arc g centering on the center of the rotation shaft 4 of the locus of movement of the tip of the kneading member 6b. The tip of the member 7a comes.

図１１に示すようにロータ１９，２１が０位置から６７．５度回転すると、混練部材６ｂの移動した軌跡ｉ内に混練部材７ａが入り込んで来るので、混練部材６ｂの移動方向の前面から後方に回り込んだ混練物の一部及び混練部材６ｂの移動した軌跡ｉ内へ入口２ａ側から出口２ｂ側方向の軸方向から送られて来る混練物の一部は混練部材６ｂに混練された後に混練部材７ａにより混練される。混練部材６ａと７ａは離れているので互いに作用し合うことなく夫々混練を行う。 As shown in FIG. 11, when the rotors 19 and 21 are rotated 67.5 degrees from the 0 position, the kneading member 7a enters the locus i where the kneading member 6b moves, so that the kneading member 6b moves backward from the front in the moving direction. After a part of the kneaded material wrapping around and a part of the kneaded material sent from the inlet 2a side to the outlet 2b side in the moving path i of the kneading member 6b is kneaded by the kneading member 6b. It is kneaded by the kneading member 7a. Since the kneading members 6a and 7a are separated from each other, kneading is performed without acting on each other.

図１１において混練部材６ｂの先端の軌跡である回転軸４を中心とする円弧ｇよりも該円弧ｇ内へ、混練部材７ａは進入を深くして行く。図１１に点ｈから始まる混練部材７ａの先端が混練物に画く軌跡である曲線ｊよりも混練部材６ｂに近い側は混練部材７ａの移動により混練部材７ａが混練物に画く軌跡外となる。単純にいえば曲線ｊと混練部材６ｂとの間は混練部材６ｂのみが作用し混練部材７ａは進入せず混練の作用もしない。 In FIG. 11, the kneading member 7a goes deeper into the arc g than the arc g centering on the rotating shaft 4 which is the locus of the tip of the kneading member 6b. In FIG. 11, the side closer to the kneading member 6b than the curve j which is the locus of the kneading member 7a starting from the point h in the kneaded product is out of the locus where the kneading member 7a is drawn on the kneaded material. Simply speaking, only the kneading member 6b acts between the curve j and the kneading member 6b, and the kneading member 7a does not enter and does not knead.

図１２に示すようにロータ１９，２１が０位置から９０度回転すると、混練部材６ｂも９０度回転し、その移動の軌跡ｉの限界である円弧ｇ内の面へ混練部材７ａの９０度回転の移動の軌跡の一部ｌ（エル）が入り込む。そこで図１０から図１２までに混練部材７ａが混練部材６ｂの移動の軌跡ｉの限界の円弧ｇ内へ入り込んだときの混練部材７ａが作用した範囲と作用しない範囲は図１２に画く曲線ｊが境となる。 As shown in FIG. 12, when the rotors 19 and 21 are rotated 90 degrees from the 0 position, the kneading member 6b is also rotated 90 degrees, and the kneading member 7a is rotated 90 degrees to the surface within the arc g which is the limit of the movement locus i. A part l (el) of the movement trajectory enters. Therefore, the range where the kneading member 7a acts and the range where the kneading member 7a does not act when the kneading member 7a enters the arc g of the limit of the trajectory i of the kneading member 6b from FIG. 10 to FIG. It becomes a boundary.

図８から図１２の説明で分かるように図１２に示す混練部材６ａ，６ｂの右側に示す曲線ｊの回転軸４側の領域は１つの混練部材６ｂによって混練物が１回混練される領域であり、曲線ｊと円弧ｇの間の領域が２つの混練部材６ｂ，７ａによって混練物が重ねて混練される領域である。 As can be seen from the description of FIGS. 8 to 12, the region on the rotating shaft 4 side of the curve j shown on the right side of the kneading members 6a and 6b shown in FIG. 12 is the region where the kneaded material is kneaded once by one kneading member 6b. There is a region between the curve j and the arc g where the kneaded material is overlapped and kneaded by the two kneading members 6b and 7a.

図１３に示すようにロータ１９，２１が図８の状態から１１２．５度、図１２の状態から２２．５度回転する際、混練部材７ａは回転軸４，５の中心を結ぶ線ＣＬからは混練部材６ｂの移動の軌跡ｉへの入り込み長さを減少させて行く。 As shown in FIG. 13, when the rotors 19 and 21 rotate 112.5 degrees from the state of FIG. 8 and 22.5 degrees from the state of FIG. 12, the kneading member 7 a moves from the line CL connecting the centers of the rotation shafts 4 and 5. Decreases the length of the kneading member 6b entering the movement path i.

図１４に示すようにロータ１９，２１が図８に示す０位置から１３５度回転すると、混練部材６ａと７ａは長さが等しく、先端が接近する。このとき、回転軸４，５の中心を結ぶ線ＣＬに対して混練部材６ａ，７ａは共に４５度の角度をなしている。混練部材６ａと７ａの先端が互に干渉しないように混練部材６ａと７ａの先端間に回転軸４，５の中心を結ぶ線ＣＬの方向で隙間ｔを設けてある。この関係は図１０と同様である。混練部材６ｂと７ａ（図１０参照）、６ａと７ａ（図１４参照）、６ａと７ｂ（図１８参照）、６ｂと７ｂ（図２２参照）の接近時は同様に先端間に隙間ｔがある。続くロータ１９，２１の回転により、混練部材７ａの移動の軌跡ｍ上には混練部材６ａが混練部材６ａの前進側の混練物を押し出すと共に入口２ａ側から出口２ｂ方向の軸方向から送られる混練物が進入する。 As shown in FIG. 14, when the rotors 19 and 21 are rotated 135 degrees from the 0 position shown in FIG. 8, the kneading members 6a and 7a are equal in length and the tips approach each other. At this time, the kneading members 6a and 7a are at an angle of 45 degrees with respect to the line CL connecting the centers of the rotary shafts 4 and 5. A gap t is provided in the direction of line CL connecting the centers of the rotary shafts 4 and 5 between the tips of the kneading members 6a and 7a so that the tips of the kneading members 6a and 7a do not interfere with each other. This relationship is the same as in FIG. When the kneading members 6b and 7a (see FIG. 10), 6a and 7a (see FIG. 14), 6a and 7b (see FIG. 18), and 6b and 7b (see FIG. 22) approach, there is a gap t between the tips. . By the subsequent rotation of the rotors 19 and 21, the kneading member 6a pushes the kneaded material on the advancing side of the kneading member 6a onto the trajectory m of the kneading member 7a and is sent from the inlet 2a side in the axial direction of the outlet 2b. An object enters.

図１５を参照して、図１４の位置からロータ１９，２１がわずかに回転すると、混練部材７ａの先端の移動の軌跡の回転軸５の中心を中心とする円弧ｎ上の点ｏ（オー）に混練部材６ａの先端が来る。 Referring to FIG. 15, when rotors 19 and 21 are slightly rotated from the position of FIG. 14, point o (O) on arc n around the center of rotation axis 5 of the locus of movement of the tip of kneading member 7 a. The tip of the kneading member 6a comes to the end.

図１５に示すようにロータ１９，２１が０位置から１５７．５度回転すると、混練部材７ａの移動した軌跡ｍ内に混練部材６ａが入り込んでくるので混練部材７ａの移動した軌跡ｍ内へ混練部材７ａの移動方向の前面から後方へ回り込んだ混練物の一部及び入口２ａ側から出口２ｂ側方向の軸方向から来る混練物の一部は混練部材６ａにより混練される。 As shown in FIG. 15, when the rotors 19 and 21 are rotated 157.5 degrees from the 0 position, the kneading member 6a enters the trajectory m moved by the kneading member 7a, so that the kneading into the trajectory m moved by the kneading member 7a. A part of the kneaded material that has come back from the front in the moving direction of the member 7a and a part of the kneaded material that comes from the axial direction in the direction from the inlet 2a to the outlet 2b are kneaded by the kneading member 6a.

図１５において混練部材７ａの先端の軌跡である回転軸５を中心とする円弧ｎよりも該円弧内へ、混練部材６ａは進入を深くして行くので図１５にｐで示す曲線よりも混練部材７ａに近い側は混練部材６ａの移動の軌跡外となる。単純にいえば曲線ｐと混練部材７aとの間は混練部材７ａのみが作用し混練部材６ａは進入せず混練の作用もしない。 In FIG. 15, the kneading member 6a goes deeper into the arc than the arc n centering on the rotation shaft 5 which is the locus of the tip of the kneading member 7a, so the kneading member is deeper than the curve indicated by p in FIG. The side close to 7a is outside the locus of movement of the kneading member 6a. Simply speaking, between the curve p and the kneading member 7a, only the kneading member 7a acts, and the kneading member 6a does not enter and does not act on kneading.

図１６に示すようにロータ１９，２１が０位置から１８０度回転すると、混練部材７ａも１８０度回転し、その移動の軌跡ｍへ混練部材６ａの１８０度回転の移動の軌跡ｑの一部が入り込む。そこで図１４から図１６までに混練部材６ａが混練部材７ａの移動の軌跡ｍへ入り込むときの混練部材６ａが作用した範囲と作用しない範囲は図１６に画く曲線ｐが境となる。 As shown in FIG. 16, when the rotors 19 and 21 are rotated 180 degrees from the 0 position, the kneading member 7a is also rotated 180 degrees, and a part of the movement path q of the kneading member 6a is rotated 180 degrees. Get in. Accordingly, the range where the kneading member 6a acts and the range where the kneading member 6a does not act when the kneading member 6a enters the movement path m of the kneading member 7a from FIG. 14 to FIG. 16 are bordered by the curve p depicted in FIG.

図８、図１６を見れば分かるように、図８において、混練部材６ａは回転軸４から回転軸５とは反対方向を向いて回転軸４，５の中心を結ぶ線ＣＬの延長線上にある。図１６において混練部材６ａは線ＣＬ上にあって回転軸４から回転軸５の方を向いている。即ち、混練部材６ａと６ｂは軸４を中心にして線ＣＬ及びその延長線上で図８と図１６では左右に入替っている。同様に混練部材７ａ，７ｂは図８と図１６では上下に入替っている。 As can be seen from FIG. 8 and FIG. 16, in FIG. 8, the kneading member 6 a is on the extension of the line CL connecting the center of the rotating shafts 4, 5 facing the direction opposite to the rotating shaft 5 from the rotating shaft 4. . In FIG. 16, the kneading member 6 a is on the line CL and faces the rotating shaft 5 from the rotating shaft 4. That is, the kneading members 6a and 6b are switched to the left and right in FIG. 8 and FIG. Similarly, the kneading members 7a and 7b are switched up and down in FIGS.

図１６から図２４への混練部材６ａ，６ｂと７ａ，７ｂの関係は図８から図１６までの混練部材６ａ，６ｂと７ａ，７ｂの関係において混練部材６ａと６ｂを入替えると共に混練部材７ａと７ｂを入替えて考えると分かるように同様である。 The relationship between the kneading members 6a, 6b and 7a, 7b from FIG. 16 to FIG. 24 is the same as the relationship between the kneading members 6a, 6b and 7a, 7b from FIG. 8 to FIG. It is the same as can be understood by replacing 7b and 7b.

かくして図２４に示すように混練部材６ａ，６ｂ，７ａ，７ｂが図８から図２４まで３６０度回転すると、混練部材６ａ，６ｂの移動の軌跡は夫々が回転軸４を除いた円ｓ内となる。同様に混練部材７ａ，７ｂの移動の軌跡は夫々が回転軸５を除いた円ｕ内となる。 Thus, as shown in FIG. 24, when the kneading members 6a, 6b, 7a, 7b rotate 360 degrees from FIG. 8 to FIG. 24, the movement trajectories of the kneading members 6a, 6b are respectively within the circle s excluding the rotating shaft 4. Become. Similarly, the movement trajectories of the kneading members 7 a and 7 b are within a circle u excluding the rotating shaft 5.

そして、ロータ１９，２１が一回転する間に円ｓ内の軌跡に対して円ｕ内の軌跡が重なる部分においては、混練部材６ａと７ａ，６ａと７ｂ，６ｂと７ａ，６ｂと７ｂの何れかの組合せが混練を行うので、この範囲の混練物は回転軸４，５の軸方向において同一位置にある異なる２本の混練部材によって混練される。混練部材６ａ，６ｂ，７ａ，７ｂが１回転する間の混練物が異なる２本の混練部材により混練する範囲は図２４に示すように９０度位相を異にするこばん形の同一の曲線ｖ，ｗの外側の範囲の如くになる。この曲線ｖ，ｗ内の夫々の長径ａは混練部材６ａの半径と６ｂの半径又は７ａの半径と７ｂの半径を加えた値である。また短径ｂは回転軸４，５の軸間距離ＣＤから混練部材６ａ，６ｂ，７ａ，７ｂの半径を減じた値の２倍である。 In the portion where the locus in the circle u overlaps with the locus in the circle s while the rotors 19 and 21 make one rotation, any of the kneading members 6a and 7a, 6a and 7b, 6b and 7a, 6b and 7b. Since these combinations knead, the kneaded material in this range is kneaded by two different kneading members located at the same position in the axial direction of the rotary shafts 4 and 5. The range in which the kneaded material is kneaded by two different kneading members during one rotation of the kneading members 6a, 6b, 7a, 7b is the same curved curve v, with a 90 ° phase difference as shown in FIG. The range is outside of w. Each major axis a in the curves v and w is a value obtained by adding the radius of the kneading member 6a and the radius of 6b or the radius of 7a and the radius of 7b. The short diameter b is twice the value obtained by subtracting the radii of the kneading members 6a, 6b, 7a, 7b from the inter-axis distance CD of the rotary shafts 4, 5.

上述のように曲線ｖ外の領域Ａ１には混練部材７ａ，７ｂが入り込んでくる。曲線ｗ外の領域Ａ２には混練部材６ａ，６ｂが入り込んでくる。これらの曲線ｖ，ｗは回転軸４，５の中心Ｃ４１，Ｃ５１について点対称である。曲線ｖとｗは形状寸法が合一であるのでこの個所以外における説明では符号はｖを用いている。 As described above, the kneading members 7a and 7b enter the region A1 outside the curve v. The kneading members 6a and 6b enter the area A2 outside the curve w. These curves v and w are point-symmetric about the centers C41 and C51 of the rotation axes 4 and 5. Since the curves v and w have the same shape and dimension, the symbol v is used in the description other than this point.

上記作用を説明する過程で混練部材６，７の夫々の移動の軌跡（先端部材７が画く円内）内の混練物は混練部材６，７と共に回転するとした。そこで曲線ｖ内の混練物は相手混練部材７によって攪拌されないし、曲線ｗ内の混練物は相手混練部材６によって攪拌されない。それ故、曲線ｖ，ｗ内の混練物は固化し易い。一旦固化すると、あたかも木の葉パドルの如く挙動することになる。故に、この実施例のように軸方向の同じ位置において木の葉パドルの長径部の先端に相当する先端部材１７を設けることにより、そして回転軸軸方向に、重ねて混練部材６，７を設けることは、簡単な構成で木の葉パドルと相当のものを提供できるものである。更に、混練部材６，７は図１に示すようにその構成部材であるフランジ１５、端板２４、先端部材１７が曲線ｖ内で曲線ｖに沿って配備されている故木の葉パドルとほぼ同様の作用を呈する。 In the process of explaining the above-described operation, the kneaded material in the locus of movement of each of the kneading members 6 and 7 (in the circle drawn by the tip member 7) rotates with the kneading members 6 and 7. Therefore, the kneaded product in the curve v is not stirred by the counterpart kneading member 7, and the kneaded product in the curve w is not stirred by the counterpart kneading member 6. Therefore, the kneaded material in the curves v and w is easily solidified. Once solidified, it will behave like a leaf paddle. Therefore, by providing the tip member 17 corresponding to the tip of the long diameter portion of the leaf paddle at the same position in the axial direction as in this embodiment, and providing the kneading members 6 and 7 in the axial direction of the rotary shaft. It is possible to provide a Konoha paddle and the equivalent with a simple configuration. Further, as shown in FIG. 1, the kneading members 6 and 7 are substantially the same as the leaf paddles of the late tree in which the constituent members of the flange 15, the end plate 24, and the tip member 17 are arranged along the curve v within the curve v. Has an effect.

ここで、木の葉パドルはここでは機構学上でいう木の葉車と形状は同様のものを採用し得る。例えば対数うず巻線を輪郭とする摩擦車と同形状の木の葉パドルを採用し得る。しかし、混練機の木の葉パドルは形状が摩擦車と同一のものを採用し得るとしても、第１の回転軸に取り付けた混練部材と第２の回転軸に取り付けた混練部材は両軸を結ぶ線上おける対向部において互に反対方向に移動し、摩擦車たり得ない。即ち、機構学でいう木の葉パドルとこの実施例でいう木の葉パドルとは作用が相違するものである。 Here, the leaf paddle can adopt the same shape as the leaf wheel referred to in terms of mechanics. For example, a leaf paddle having the same shape as a friction wheel having a logarithmic spiral winding as an outline can be adopted. However, even if the leaf paddle of the kneading machine can adopt the same shape as the friction wheel, the kneading member attached to the first rotating shaft and the kneading member attached to the second rotating shaft are on the line connecting both shafts. It moves in the opposite direction to each other at the facing part, and it cannot be a friction wheel. That is, the action of the leaf paddle in the mechanics is different from that in the embodiment.

機構学上の木の葉車では平行する２軸は互に反対方向に回転し、対向する摩擦車は接触部で転動する。木の葉パドルは対向部では仮に接触するようにしたとしても必ずすべり接触である。それ故、本例の混練部材６，７は、混練という目的に照して木の葉パドルをなす曲線ｖ内あり、且つ曲線ｖに沿って設けられておれば、曲線ｖに対して凹凸をなしていても差支えないものである。 In a mechanistic tree wheel, two parallel axes rotate in opposite directions, and the opposing friction wheel rolls at the contact portion. Even if the leaf paddle is in contact with the opposite part, it is always in sliding contact. Therefore, the kneading members 6 and 7 of the present example are not uneven with respect to the curve v as long as the kneading members 6 and 7 are within the curve v forming the leaf paddle for the purpose of kneading and are provided along the curve v. There is no problem.

次に混練部材６，７の具体的な形状についてのべる。 Next, the specific shapes of the kneading members 6 and 7 will be described.

図１に示すように、先端部材１７は舌部１７ａ，１７ｂ側の角１７ｃが曲線ｖに接している。この角１７ｃは丸面取り形状である。端板２４の縁２４ｃと２４ｄが交叉する角２４ｅは曲線ｖとわずかに離れているが曲線ｖと角２４ｅを一致させてもよい。縁２４ｂと２４ｃの角２４ｆは曲線ｖと接近しているが角２４ｆと曲線ｖは一致させてもよい。 As shown in FIG. 1, the tip member 17 has a corner 17c on the side of the tongues 17a and 17b in contact with the curve v. The corner 17c has a round chamfer shape. The angle 24e where the edges 24c and 24d of the end plate 24 intersect is slightly separated from the curve v, but the curve v and the angle 24e may be matched. The corner 24f of the edges 24b and 24c is close to the curve v, but the corner 24f and the curve v may coincide with each other.

フランジ１５の端部１５ｆは曲線ｖと離れているが曲線ｖまでのばすことができる。回転軸４，５の直径は曲線ｖ，ｖで囲まれた図形の短径ｖ１−ｖ１（＝ｂ）が選択できる最大径である。 The end 15f of the flange 15 is separated from the curve v, but can extend up to the curve v. The diameters of the rotating shafts 4 and 5 are the maximum diameters that can be selected from the minor axis v1−v1 (= b) of the figure surrounded by the curves v and v.

上述のように、混練部材６，７は曲線ｖ，ｖで囲まれた範囲内で、且つ、曲線ｖ，ｖに近づけて配設してある。そして、取付フランジ１５、ねじ部材１８、突出部１６、先端部材１７を通じて曲線ｖ，ｖと対向する曲線ｖ，ｖ内の混練部材部分の形状は凹凸が繁しい複雑な形状であるため、混練部材６，７の構成部材、回転軸４，５と曲線ｖ間の空間Ｓでは混練物は滞留し易く、固化し易い。それ故、回転軸４，５、混練部材６，７回りの空間Ｓは固化した混練物で充たされ、あたかも木の葉パドルのようになる。ここで空間Ｓとは曲線ｖ，ｖで囲まれた内部空間であって、回転軸４，５、混練部材６，７を除く空間のことである。 As described above, the kneading members 6 and 7 are disposed within the range surrounded by the curves v and v and close to the curves v and v. The shape of the kneading member portion in the curves v, v facing the curves v, v through the mounting flange 15, the screw member 18, the projecting portion 16, and the tip member 17 is a complicated shape with many irregularities. In the space S between the constituent members 6 and 7 and the rotary shafts 4 and 5 and the curve v, the kneaded material tends to stay and solidify easily. Therefore, the space S around the rotary shafts 4 and 5 and the kneading members 6 and 7 is filled with the solidified kneaded material, as if it is a leaf paddle. Here, the space S is an internal space surrounded by the curves v and v, and is a space excluding the rotating shafts 4 and 5 and the kneading members 6 and 7.

そして、図２５、図２６に示すように、このような混練部材６，７は回転軸４，５の軸方向において、隣接する混練部材６，７は端面２４ｇで一定方向にスパイラル面上において互にくい違い接触しているので、端面２４ｇ同士の接触の範囲で回転軸４，５回りを周方向に混練物の移動は制約されている。そして、回転軸４，５の軸方向において、各混練部材６，７はスパイラル状に配設されているのでロータ１９，２１の回転によって回転軸４，５の軸方向に混練物を送る。
混練物が軸方向に送られる際は軸方向に隣接する混練部材間に段状の差が周方向にあるため、混練部材外周の凹凸部と併せて混練が行われる。この実施例１の混練部材は回転軸の軸方向の同一個所で、直径の両側にわたって半径方向の片側に設けてもよい。この場合、混練部材は回転軸回りに一重のスパイラル状に配設される。 As shown in FIGS. 25 and 26, the kneading members 6 and 7 are in the axial direction of the rotary shafts 4 and 5, and the adjacent kneading members 6 and 7 are arranged on the spiral surface in a fixed direction at the end face 24g. Since the contact is difficult, the movement of the kneaded material is restricted in the circumferential direction around the rotation axes 4 and 5 within the range of contact between the end faces 24g. Since the kneading members 6 and 7 are arranged in a spiral shape in the axial direction of the rotating shafts 4 and 5, the kneaded material is fed in the axial direction of the rotating shafts 4 and 5 by the rotation of the rotors 19 and 21.
When the kneaded material is fed in the axial direction, there is a step difference between the kneading members adjacent in the axial direction in the circumferential direction, so that kneading is performed together with the uneven portions on the outer periphery of the kneading member. The kneading member of the first embodiment may be provided on one side in the radial direction over the both sides of the diameter at the same position in the axial direction of the rotating shaft. In this case, the kneading member is arranged in a single spiral around the rotation axis.

（混練部材の実施例２）
混練部材の実施例２について説明する。 (Example 2 of kneading member)
Example 2 of the kneading member will be described.

図３は回転軸の軸方向から見る混練部材を示している。図４は図３の平面図である。 FIG. 3 shows the kneading member viewed from the axial direction of the rotating shaft. FIG. 4 is a plan view of FIG.

回転軸４，５は本例では面取りされた角軸である。取付フランジ１５は一つの隅１５ｈを間にして角軸の一面４ｊ，５ｊに接する面１５ｊと、角軸４，５の面４ｊ，５ｊに直角な面４ｉ，５ｉに接する面１５ｉを有する。したがって、取付フランジ１５は回転軸４，５の角４ｍ，５ｍにまたがっている。ただし、フランジ１５の主要部は回転軸４，５の面４ｊ，５ｊに接し、位置決めをするための端部１５ｍが回転軸４，５の面４ｉ，５ｉに接する。面１５ｉは面４ｉ，５ｉの辺幅に比して小さい。フランジ１５の表面には突出部１６を有する。この突出部１６はフランジ１５の一方の端部１５ｍのある側に寄せて設けてある。突出部１６の突出端１６ａには焼結合金等の先端部材１７が設けてある。前実施例では先端部材１７は突出端１６ａの両側へ舌部１７ａ，１７ｂを設けた（図１参照）がこの実施例２では舌部１７ｂはロータ１９，２１の回転方向イ、ロで見て突出部１６の前進側の面１６ｂに回り込んでいるだけである。角１７ｃは曲線ｖ，ｖに接している。 The rotating shafts 4 and 5 are chamfered angular axes in this example. The mounting flange 15 has a surface 15j in contact with one surface 4j, 5j of the angular axis with one corner 15h in between, and a surface 15i in contact with the surfaces 4i, 5i perpendicular to the surfaces 4j, 5j of the angular axes 4, 5. Therefore, the mounting flange 15 extends over the corners 4 m and 5 m of the rotary shafts 4 and 5. However, the main part of the flange 15 is in contact with the surfaces 4j and 5j of the rotary shafts 4 and 5, and the end 15m for positioning is in contact with the surfaces 4i and 5i of the rotary shafts 4 and 5. The surface 15i is smaller than the side width of the surfaces 4i and 5i. The surface of the flange 15 has a protrusion 16. The protrusion 16 is provided close to the side of the flange 15 where one end 15m is located. A projecting end 16 a of the projecting portion 16 is provided with a tip member 17 such as a sintered alloy. In the previous embodiment, the tip member 17 is provided with tongue portions 17a and 17b on both sides of the protruding end 16a (see FIG. 1). In this embodiment 2, the tongue portion 17b is viewed in the rotational directions A and B of the rotors 19 and 21. It only wraps around the forward surface 16b of the protrusion 16. The corner 17c is in contact with the curves v and v.

実施例１に示す舌部１６ａは実施例２では有しない。混練部材６，７としての半径方向の突出長さＲは回転軸４，５の中心Ｃ４１，Ｃ５１から曲線ｖ，ｖで示される木の葉車の長径上の線ｘと先端部材１７の交差する点ａ１までの長さである。舌部のない角１７ｃ側は木の葉車の短径上の線ｙからの距離が長さＲを越えているがこの角１７ｃは曲線ｖと接している。 The tongue portion 16a shown in the first embodiment is not included in the second embodiment. The radial protrusion length R of the kneading members 6 and 7 is a point a1 where the tip member 17 intersects the line x on the major axis of the leaf wheel indicated by the curves v and v from the centers C41 and C51 of the rotating shafts 4 and 5. Is the length. On the corner 17c side without the tongue, the distance from the line y on the minor axis of the foliage wheel exceeds the length R, but this corner 17c is in contact with the curve v.

フランジ１５と突出部１６は溶接部ｗ１，ｗ１でもって結合して一体化されている。この実施例２の混練部材６，７の回転軸４，５の軸方向と同方向の両端面６ｆ，７ｆはフランジ１５、突出部１６、先端部材１７を通じて回転軸４，５の中心線に対して直角な共通の一平面である。既に図８から図２４においてのべた先端部材１７が混練物に画く軌跡である曲線ｖで囲まれた内部に回転軸４，５、混練部材６，７が納まる。そこで、曲線ｖでなる図形の長径をとおる線ｘは回転軸４，５の対向する辺の中心をとおる線ｚとは回転軸４，５の中心Ｃ４１，Ｃ５１（Ｃ４１は回転軸４の中心、Ｃ５１は回転軸５の中心）において角θをなして交叉している。 The flange 15 and the protrusion 16 are combined and integrated with the welded portions w1 and w1. Both end surfaces 6f and 7f of the kneading members 6 and 7 of the second embodiment in the same direction as the axial directions of the rotary shafts 4 and 5 are connected to the center line of the rotary shafts 4 and 5 through the flange 15, the protruding portion 16, and the tip member 17. It is a common plane that is perpendicular to each other. The rotary shafts 4 and 5 and the kneading members 6 and 7 are already housed in the interior surrounded by the curve v which is the locus of the solid tip member 17 drawn in the kneaded material in FIGS. Therefore, the line x passing through the major axis of the figure formed by the curve v is the line z passing through the center of the opposite sides of the rotating shafts 4 and 5 and the center C41, C51 of the rotating shafts 4 and 5 (C41 is the center of the rotating shaft 4, C51 crosses at an angle θ at the center of the rotating shaft 5).

回転軸４，５への混練部材６，７の取り付けはフランジ１５の取付穴１５ａを挿通して六角ボルトのようなねじ部材１８を回転軸４，５に設けてあるめねじにねじ込むことによる。このねじ部材１８の位置は曲線ｖを越えない範囲において突出部１６からの距離が可能な限り大きくなるようにしてある。 The kneading members 6 and 7 are attached to the rotary shafts 4 and 5 by inserting screw members 18 such as hexagon bolts into female screws provided on the rotary shafts 4 and 5 through the mounting holes 15a of the flange 15. The position of the screw member 18 is set such that the distance from the protrusion 16 is as large as possible within a range not exceeding the curve v.

実施例２においても、実施例１と同様に曲線ｖと回転軸４，５及び混練部材６，７間の空間Ｓは混練物が固着し易い。混練作用により生ずる混練部材の挙動は実施例１と同様である。 Also in the second embodiment, the kneaded material is easily fixed in the space V between the curve v, the rotary shafts 4 and 5, and the kneading members 6 and 7, as in the first embodiment. The behavior of the kneading member generated by the kneading action is the same as that of the first embodiment.

空間Ｓの範囲についてみると、ロータ１９，２１の外方に対する境界を曲線ｖとして回転軸４，５、混練部材６，７をこの境界内に納めると共にこの曲線ｖに近づける。先端部材１７は角１７ｃで曲線ｖに接している。角１７ｃは先端部材１７の角面取り状部分の一点であり、軸方向には直線となる。ねじ部材１８の六角ボルトはその頭１８ｂが曲線ｖに近い位置にある。頭１８ｂは曲線ｖを越えない。フランジ１５は角１５ｅが曲線ｖに接近している。回転軸４，５の角４ａ，５ａは曲線ｖと一致している。 As for the range of the space S, the boundary with respect to the outside of the rotors 19 and 21 is set as a curve v, and the rotary shafts 4 and 5 and the kneading members 6 and 7 are accommodated in the boundary and brought close to the curve v. The tip member 17 is in contact with the curve v at a corner 17c. The corner 17c is one point of a chamfered portion of the tip member 17, and is a straight line in the axial direction. The hexagon bolt of the screw member 18 has a head 18b close to the curve v. The head 18b does not exceed the curve v. The flange 15 has a corner 15e approaching the curve v. The corners 4a and 5a of the rotating shafts 4 and 5 coincide with the curve v.

この実施例２は空間Ｓが凹凸が多く凸部が曲線ｖに近づく、又は、一致する角部が多いので空間Ｓには混練物が滞留し易く、滞留固化により木の葉パドルが形成される。 In Example 2, since the space S has many irregularities and the convex part approaches the curve v, or there are many coincident corners, the kneaded material tends to stay in the space S, and a leaf paddle is formed by staying solidification.

実施の形態では混練部材６，７の回転軸の直径をわたる両側への半径方向突出長さを等しくしたが半径方向突出長さが相違していてもよい。 In the embodiment, the radial protrusion lengths on both sides across the diameter of the rotation shaft of the kneading members 6 and 7 are made equal, but the radial protrusion lengths may be different.

上述したように、この発明の実施例はトラフを開放するだけで混練部材を取り外せるようにしただけでなく、混練を行うだけでほぼ木の葉パドルを備えたロータと同様の混練効果を奏することができる。混練部材及びロータの製作に困難性がない。 As described above, the embodiment of the present invention not only enables the kneading member to be removed by simply opening the trough, but also can provide the same kneading effect as a rotor having a leaf paddle only by kneading. . There is no difficulty in manufacturing the kneading member and the rotor.
