Description
本発明は造粒物の圧縮成型装置に関する。さらに詳しくは、原料、たとえば粉体原料を一対の加圧ロールにより圧縮成形して造粒物、いわゆるタブレットやブリケットなどを製造する圧縮成型装置に関する。 The present invention relates to a granulation product compression molding apparatus. More specifically, the present invention relates to a compression molding apparatus for producing a granulated product, so-called tablet or briquette, by compressing a raw material, for example, a powder raw material with a pair of pressure rolls.
従来、両持構造の単独の回転ドラムの外周に備える多数の型孔に、進退杆に連結される複数のピン（ラム）を進退自在に挿入し、進退杆を介してピンを半径方向に進退させて原料を圧縮成型およびその取り出しをさせる圧縮成型装置がある（例えば、特許文献１参照）。この装置においては、回転ドラムを軸支する軸受体の側面に、進退杆の外周方向への揺動的進退の案内をさせるために、進退杆の突出端を挿入させる凹部を有する案内部を設けるようにしたピン押し出し機構を用いている。 Conventionally, a plurality of pins (rams) connected to advancement and retraction are inserted into a large number of mold holes provided on the outer periphery of a single rotating drum having a both-end support structure, and the pins are advanced and retracted in the radial direction via advancement and retraction. There is a compression molding device that compresses and takes out a raw material (see, for example, Patent Document 1). In this apparatus, a guide portion having a recess for inserting a protruding end of the advance / retreat lever is provided on the side surface of the bearing body that pivotally supports the rotating drum in order to guide the forward / backward movement of the advance / retreat operation in the outer circumferential direction. A pin pushing mechanism is used.
前記特許文献１記載の圧縮成型機は、進退杆、すなわちピンが進退自在であり、ピンと成型孔と当金とで形成される閉空間において圧縮成型が行われるため、造粒物の外観や寸法精度は良い。しかし、該ピンの押し出し機構が軸受体の側面に設けられる案内部の凹部に進退杆の突出端を挿入させて案内させるようにしているため、構造が複雑となり、成型孔の数を増やして生産性を上げることが難しい、という問題を残している。 The compression molding machine described in Patent Document 1 is capable of advancing and retreating, that is, the pin is movable back and forth, and compression molding is performed in a closed space formed by the pin, the molding hole, and the metal, so the appearance and dimensions of the granulated product The accuracy is good. However, the pin push-out mechanism is guided by inserting the protruding end of the advancing and retracting guide into the recess of the guide part provided on the side of the bearing body, which makes the structure complicated and increases the number of molding holes. It remains a problem that it is difficult to improve.
そこで、本発明は、叙上の事情に鑑み、ピンの押出し機構を簡略にして装置コストの低減と成型孔数の増大ができるとともに、造粒物の生産性を向上させることができる圧縮成型装置を提供することを目的とする。 Therefore, in view of the above circumstances, the present invention provides a compression molding apparatus that can simplify the pin extrusion mechanism, reduce the apparatus cost, increase the number of molding holes, and improve the productivity of the granulated product. The purpose is to provide.
本発明の造粒物の圧縮成型装置は、両端部が支持される一対の加圧ロールにより原料を圧縮成型して造粒物を製造する圧縮成型装置であって、前記一対の加圧ロールのうち、少なくとも一方の加圧ロールが中空形状を呈しており、該加圧ロールの外周部に所定の個数の成型孔を有するとともに、各成型孔に挿入される圧縮ピンが摺動自在に内装されており、かつ該中空形状の加圧ロールの内部の軸心方向に前記圧縮ピンを押し出すための押出し手段を内装してなることを特徴としている。
また、前記一方の加圧ロールの周速度が他方の加圧ロールの周速度より小さいのが好ましい。
The compression molding apparatus of the granulated product of the present invention is a compression molding apparatus for producing a granulated product by compression molding a raw material with a pair of pressure rolls supported at both ends, and comprising the pair of pressure rolls. Among them, at least one of the pressure rolls has a hollow shape, and has a predetermined number of molding holes on the outer peripheral portion of the pressure roll, and compression pins inserted into the molding holes are slidably incorporated. And an extrusion means for pushing out the compression pin in the axial direction inside the hollow pressure roll is provided.
Moreover, it is preferable that the circumferential speed of said one pressure roll is smaller than the circumferential speed of the other pressure roll.
本発明によれば、加圧ロールを両持構造とすることにより装置の構造的な強度を高め、加圧ロールの加圧幅が広げられる。また、一対の加圧ロールの外周部の成型孔に圧縮ピンを摺動自在にするとともに、該圧縮ピンの押出し手段を中空形状の加圧ロールの内部の軸心方向に内装させるようにしている。
このため、造粒物を取り出す圧縮ピンの押出し手段を簡単にでき、ピンの数を増やすことができる。したがって、装置コストの低減を図るとともに、造粒物を生産性よく成型することができる。
また、一方の加圧ロールの周速度を他方の加圧ロールの周速度より小さくすると、加圧ロール間にせん断が働くため、バリがない外観や寸法精度のよい造粒物が得られる。
According to the present invention, the pressure roll has a both-end support structure, thereby increasing the structural strength of the apparatus and widening the pressure width of the pressure roll. Further, the compression pin is made slidable in the molding hole in the outer peripheral portion of the pair of pressure rolls, and the extrusion means for the compression pin is arranged in the axial direction inside the hollow pressure roll. .
For this reason, the extrusion means of the compression pin which takes out a granulated material can be simplified, and the number of pins can be increased. Therefore, the apparatus cost can be reduced and the granulated product can be molded with high productivity.
Moreover, when the peripheral speed of one pressure roll is made smaller than the peripheral speed of the other pressure roll, shearing works between the pressure rolls, so that a granulated product having no appearance and good dimensional accuracy can be obtained.
以下、添付図面に基づいて本発明の造粒物の圧縮成型装置を説明する。本発明の一実施の形態にかかわる造粒物の圧縮成型装置は、原料、たとえば粉状の物質をタブレットに圧縮成型するロール圧縮式成型機であって、図１〜３に示されるように、ケーシングＡの両側部内に組み込まれた、たとえばころ軸受、軸受ハウジング、内輪インナー部材および締め付け部材を具備する２組の軸受ユニットＢ１、Ｂ２と、円柱状を成すとともに相対向し、矢印Ｒ１、Ｒ２で示されるように、それぞれが内側方向へ回転可能に配設される中空形状の一対の加圧ロール１、２と、該中空形状の加圧ロール１、２の内部の軸心方向に内装される前記圧縮ピンを押し出すための押出し手段Ｃと、該加圧ロール１、２間の上方に配設されて加圧ロール１、２間に粉状の物質を送り込む供給手段としてのホッパー３とを備えている。なお、図において、符号４、５はカバーである。 The granulated product compression molding apparatus of the present invention will be described below with reference to the accompanying drawings. A granulation compression molding apparatus according to an embodiment of the present invention is a roll compression molding machine that compresses a raw material, for example, a powdery substance into a tablet, as shown in FIGS. Two pairs of bearing units B1 and B2, which are incorporated in both side portions of the casing A, for example, each having a roller bearing, a bearing housing, an inner ring inner member and a tightening member, form a columnar shape and are opposed to each other by arrows R1 and R2. As shown, a pair of hollow pressure rolls 1 and 2 that are rotatably arranged in the inner direction, and an axial center inside the pressure rolls 1 and 2 are hollow. An extrusion means C for extruding the compression pin; and a hopper 3 as a supply means that is disposed above the pressure rolls 1 and 2 and feeds a powdery substance between the pressure rolls 1 and 2. ing. In the figure, reference numerals 4 and 5 denote covers.
前記加圧ロール１、２は分割構造であって、図３に示されるように、円筒状の外周部６ａ、７ａと小径の軸端部６ｂ、７ｂとからなるロール本体部６、７と、該ロール本体部６、７の開口部面にボルト８により固着されるリング状の支持部材９、１０とを具備している。この加圧ロール１、２は、軸端部６ｂ、７ｂが前記軸受ユニットＢ１に回転支持されているとともに、支持部材９、１０がロール本体部６、７の開口部側に固定される内装軸１１、１２を内装した状態で軸受１３により回転支持され、いわゆるロールの加圧幅を広げた両持の状態にされている。そして、ロール本体部６、７と内装軸１１、１２とは、インロウ構造によって同心円状に結合されている。
また、前記内装軸１１、１２の先端部はロール本体部６、７の内壁に形成される開口部に組み込まれているパイロット軸受１４に回転支持にされている。なお、内装軸１１、１２は、ブラケット１５、１６によって固定されているため、回転することはない。
これにより、加圧ロール１、２は、軸端部６ｂ、７ｂ側に連結される電動機と減速手段（図示せず）により、外周速度が相違するようにしてそれぞれが回転できるようにされている。
さらに、図２〜３に示されるように、前記ロール本体部６、７の外周部６ａ、７ａには、前記加圧ロール１、２の半径方向に放射状に指向する所定の個数のタブレット用成型孔１７が穿通されている。
そして、この成型孔１７に対しては、タブレットの押出のための圧縮ピン１８が挿通されており、この圧縮ピン１８は、図２に示すように、前記加圧ロール１または２の半径方向へ指向しかつ所要長さ摺動自在である。ここで、圧縮ピン１８は、押出時にロール外側に脱落するのを防ぐため、段付構造となっている。
本実施の形態における前記押出し手段Ｃは、前記内装軸１１、１２と該内装軸１１、１２の外周面に前記圧縮ピン１８に対向して設けられるカム部１９、２０とから構成されている。この押出し手段Ｃは、加圧ロール１、２の内部の軸心方向に内装されているため、圧縮ピン１８をロール全幅に渡って押し出すことができる。
The pressure rolls 1 and 2 have a split structure, and as shown in FIG. 3, roll main body portions 6 and 7 including cylindrical outer peripheral portions 6a and 7a and small-diameter shaft end portions 6b and 7b, Ring-shaped support members 9 and 10 fixed to the opening surface of the roll body portions 6 and 7 by bolts 8 are provided. The pressure rolls 1 and 2 have shaft ends 6 b and 7 b that are rotatably supported by the bearing unit B 1, and support shafts 9 and 10 that are fixed to the opening side of the roll main bodies 6 and 7. 11 and 12 are rotatably supported by a bearing 13 in a state in which they are housed, and are in a state of being both-supported with a so-called roll pressurization width widened. The roll body portions 6 and 7 and the interior shafts 11 and 12 are concentrically coupled by an in-row structure.
Further, the tip ends of the interior shafts 11 and 12 are rotatably supported by a pilot bearing 14 incorporated in an opening formed in the inner wall of the roll main body portions 6 and 7. Since the interior shafts 11 and 12 are fixed by the brackets 15 and 16, they do not rotate.
Thereby, the pressure rolls 1 and 2 can be rotated by the motor connected to the shaft end portions 6b and 7b and the speed reduction means (not shown) so that the outer peripheral speeds are different. .
Furthermore, as shown in FIGS. 2 to 3, a predetermined number of tablet moldings radially oriented in the radial direction of the pressure rolls 1 and 2 are formed on the outer peripheral portions 6 a and 7 a of the roll body portions 6 and 7. A hole 17 is penetrated.
A compression pin 18 for extruding the tablet is inserted into the molding hole 17, and the compression pin 18 extends in the radial direction of the pressure roll 1 or 2 as shown in FIG. Oriented and slidable for the required length. Here, the compression pin 18 has a stepped structure in order to prevent it from falling off the roll during extrusion.
The push-out means C in the present embodiment includes the interior shafts 11 and 12 and cam portions 19 and 20 provided on the outer peripheral surfaces of the interior shafts 11 and 12 so as to face the compression pin 18. Since the pushing means C is built in the axial direction inside the pressure rolls 1 and 2, the compression pin 18 can be pushed out over the entire width of the roll.
なお、本実施の形態におけるロール圧縮式成型機の場合、前記加圧ロール１、２は直径が１６０ｍｍであり、また前記成型孔１７は内径が１２ｍｍであり、さらに前記圧縮ピン１８は５ｍｍ移動可能にされている。 In the case of the roll compression molding machine according to the present embodiment, the pressure rolls 1 and 2 have a diameter of 160 mm, the molding hole 17 has an inner diameter of 12 mm, and the compression pin 18 is movable by 5 mm. Has been.
また、図２に示されるように、前記加圧ロール１の斜め下方位置には、円柱状を成すとともにこの加圧ロール１と同一方向へ指向しかつ加圧ロール１の外周速度よりも速い外周速度で内側の矢印方向Ｒ３へ回転する補助ロール２１が、前記加圧ロール１に対向して配設されている。この補助ロール２１は、電動機と減速機（図示せず）に接続されている。
なお、図２における符号２２および２３は前記加圧ロール１、２および補助ロール２１の外周面に対して別途固定配設されたスクレーパである。
Further, as shown in FIG. 2, the outer periphery of the pressure roll 1 is formed at a diagonally lower position and has a cylindrical shape and is directed in the same direction as the pressure roll 1 and is faster than the outer peripheral speed of the pressure roll 1. An auxiliary roll 21 that rotates in the inner arrow direction R <b> 3 at a speed is disposed to face the pressure roll 1. The auxiliary roll 21 is connected to an electric motor and a speed reducer (not shown).
Note that reference numerals 22 and 23 in FIG. 2 are scrapers separately fixed to the outer peripheral surfaces of the pressure rolls 1 and 2 and the auxiliary roll 21.
このように構成したロール圧縮式成型機は、加圧ロール１を外周速度が０．０４ｍ／ｓｅｃでかつ加圧ロール２を外周速度が０．０６ｍ／ｓｅｃで矢印方向Ｒ１、Ｒ２へそれぞれ回転させるとともに、粉状の物質をホッパー３に投入して加圧ロール１、２間に送り込む。すると、粉状の物質はまず加圧ロール１、２の成型孔１７によって短尺円柱状に圧縮成型されるとともに、加圧ロール１、２の外周速度の相違により、圧縮生成されたタブレットの外側先端部にせん断力が作用して、加圧ロール２における成型孔１７内のタブレットのバリが除去される。 The roll compression molding machine thus configured rotates the pressure roll 1 in the arrow directions R1 and R2 at an outer peripheral speed of 0.04 m / sec and the pressure roll 2 at an outer peripheral speed of 0.06 m / sec. At the same time, a powdery substance is put into the hopper 3 and fed between the pressure rolls 1 and 2. Then, the powdery substance is first compression-molded into a short cylindrical shape by the molding holes 17 of the pressure rolls 1 and 2, and the outer tip of the tablet generated by compression due to the difference in the outer peripheral speed of the pressure rolls 1 and 2. A shearing force acts on the part, and the burr of the tablet in the molding hole 17 in the pressure roll 2 is removed.
これに伴い、加圧ロール２における成型孔１７内のタブレットはバリが除去されたまま内装軸１２のカム部２０まで移動され、続いて、加圧ロール２の回転に伴って複数の圧縮ピン１８がカム部２０によって順次押出され、この結果、複数の成型孔１７内のタブレットＷは、成型孔１７内から順次押出される。 Along with this, the tablet in the molding hole 17 in the pressure roll 2 is moved to the cam portion 20 of the interior shaft 12 with the burrs removed, and subsequently, the plurality of compression pins 18 as the pressure roll 2 rotates. Are sequentially extruded by the cam portion 20, and as a result, the tablets W in the plurality of molding holes 17 are sequentially extruded from the molding holes 17.
一方、加圧ロール１における成型孔１７内のタブレットは、バリがついたまま補助ロール２１まで移動されたのち、加圧ロール１の外周速度より速い外周速度で矢印方向Ｒ３へ回転する補助ロール２１によってバリが除去され、その後、前述の加圧ロール２と同様にして、タブレットＷを得ることができる。 On the other hand, the tablet in the molding hole 17 in the pressure roll 1 is moved to the auxiliary roll 21 with burrs, and then rotated in the arrow direction R3 at an outer peripheral speed faster than the outer peripheral speed of the pressure roll 1. Then, the burrs are removed, and then the tablet W can be obtained in the same manner as the pressure roll 2 described above.
押出が終わった後、圧縮ピン１８は、次の成型工程において、加圧ロール１、２のかみ込みによって生ずる原料の圧力によって押し戻される。 After the extrusion is finished, the compression pin 18 is pushed back by the pressure of the raw material generated by the biting of the pressure rolls 1 and 2 in the next molding step.
なお、本実施の形態では、前記一対の加圧ロールが両持の中空形状を呈しているが、本発明においては、これに限定されるものではなく、この一対の加圧ロールのうち、少なくとも一方の加圧ロールを両持の中空形状とすることができる。この場合、他方の加圧ロールとしては、成型孔１７は設けられず、分割でなく、一体で中実の両持となる形状の加圧ロールを用いることができる。
また、本実施の形態では、原料の圧縮成型のための分割構造の加圧ロール１、２および押出し手段Ｃが単純であるため、図４に示されるような成型孔１７の配列が可能である。たとえば、圧縮ピン１８の成型部の直径をｄｍｍとすると、加圧ロールの径の大きさにかかわらず、周方向のピッチを１．０１ｄ〜１０ｄｍｍおよび軸方向のピッチを１．０１ｄ〜１０ｄｍｍとすることができるため、かかる成型孔１７の配列を有する加圧ロール３１を用いることにより、バリがなく外観や寸法精度がよい造粒物の生産量を大幅に増やすことが可能となる。
In the present embodiment, the pair of pressure rolls has a both-end supported hollow shape, but the present invention is not limited to this, and at least one of the pair of pressure rolls. One pressure roll can be made into a hollow shape with both ends. In this case, as the other pressurizing roll, the forming hole 17 is not provided, and a pressurizing roll having a shape that is integral and solid both ends, not divided, can be used.
Further, in the present embodiment, since the divided pressure rolls 1 and 2 and the extrusion means C for the compression molding of the raw material are simple, the molding holes 17 as shown in FIG. 4 can be arranged. . For example, if the diameter of the molding portion of the compression pin 18 is dmm, the circumferential pitch is 1.01d to 10dmm and the axial pitch is 1.01d to 10dmm regardless of the diameter of the pressure roll. Therefore, by using the pressure roll 31 having such an array of the molding holes 17, it is possible to greatly increase the production amount of the granulated product without burr and having good appearance and dimensional accuracy.
また、圧縮ピン１８の押出し手段Ｃとして内装軸１１、１２とカム部１９、２０を用いているが、本発明においては、これに限定されるものではなく、エアシリンダまたは電動シリンダを用いることができる。たとえばエアシリンダを用いる場合には、エアシリンダは圧縮ピン１８ひとつにつき1台、あるいは複数個につき１台、加圧ロールとともに回転するように設置される。また、このエアシリンダのホースは外部圧縮空気源の配管と回転継手によって接続されるとともに、圧縮ピンを押し出すタイミングはシーケンス制御される。
さらに、本実施の形態では原料を供給する手段として、重力供給によるホッパー３を用いているが、従来のロール圧縮式成型機で慣用手段として利用されるスクリューフィーダによって供給してもよい。
Moreover, although the internal shafts 11 and 12 and the cam parts 19 and 20 are used as the pushing means C of the compression pin 18, the present invention is not limited to this, and an air cylinder or an electric cylinder may be used. it can. For example, when an air cylinder is used, one air cylinder is installed to rotate with the pressure roll, one for each compression pin 18 or one for a plurality of compression pins 18. The hose of the air cylinder is connected to the external compressed air source pipe by a rotary joint, and the timing for pushing out the compression pin is sequence-controlled.
Furthermore, in this embodiment, the hopper 3 by gravity supply is used as a means for supplying the raw material, but it may be supplied by a screw feeder used as a conventional means in a conventional roll compression molding machine.
また、本実施の形態では、一対の加圧ロール１、２の周速を異速にしているため、原料として、ある程度強度がある繊維分を含む原料を使用する場合、圧縮力とせん断力が同時に働くことにより繊維分を分離しながら固化を行うため、寸法のよいタブレットを効率的に製造することができる。
しかしながら、原料の種類によっては、一対の加圧ロールの周速を同一にすることもできる。
Moreover, in this Embodiment, since the peripheral speed of a pair of pressurization rolls 1 and 2 is made into different speed, when using the raw material containing a fiber part with a certain amount of strength as a raw material, compressive force and shear force are Since solidification is performed while separating the fiber components by working at the same time, a tablet with good dimensions can be efficiently produced.
However, depending on the type of raw material, the peripheral speeds of the pair of pressure rolls can be the same.
