Description
本発明は、トロンメルの改良に関するものである。 The present invention relates to an improvement of trommel.
木材を皮剥機で皮剥した時に排出される樹皮（バーク）や、皮剥した木材を破砕したチップは、その大きさにバラツキがあるので、篩分けして一定の大きさのものに選別している。この篩分けする選別装置としては、スクリーンを横動させる水平回転選別装置（特許文献１）と、円筒状スクリーンを回転させる横置き型トロンメル（特許文献２）とがある。 Bark (bark) that is discharged when timber is peeled off with a peeling machine, and chips that are crushed from peeled timber vary in size, so they are sieved and sorted to a certain size. . As a sorting device for sieving, there are a horizontal rotation sorting device (Patent Document 1) for moving a screen laterally and a horizontal trommel (Patent Document 2) for rotating a cylindrical screen.
従来の水平回転選別装置は、スクリーンを横動させるので、これを支持する基台の基礎工事に多大の費用がかかる問題がある。また横置き型トロンメルは、円筒状スクリーンの内側に回転軸を挿入して、モータで回転軸を回転させ、これと一体に接続した円筒状スクリーンを回転させて、投入された原料を選別するもので、大きさの異なる被選別材を３種類の大きさに選別するためには、大きさの異なる透過孔を開孔した２種類の多孔板を巻回しなければならず円筒状スクリーンの長さが長くなって装置が大型化する問題があった。 Since the conventional horizontal rotation sorter moves the screen laterally, there is a problem that the foundation work for supporting the base is expensive. In addition, the horizontal type trommel inserts a rotating shaft inside the cylindrical screen, rotates the rotating shaft with a motor, and rotates the cylindrical screen connected integrally therewith to select the input raw material. In order to sort materials to be sorted into three different sizes, two types of perforated plates having different sizes of perforated holes must be wound, and the length of the cylindrical screen However, there is a problem that the size of the apparatus becomes large.
このため本発明者は、先に内側円筒スクリーンの外周に外側円筒スクリーンを一体に形成した二重円筒スクリーンを作成し、傾斜した基台の上方側に従動ローラと、下方側にモ−タに接続した駆動ローラをそれぞれ２個ずつ取付けて、これらの上に二重円筒スクリーンを回転自在に支持し、二重円筒スクリーンの外周にリング状のツバ部を突設し、このツバ部の両側に、押えローラを取付けて、二重円筒スクリーンの移動を防止した二重トロンメルを開発した。しかしながら重量のある二重円筒スクリーンを、この外周に取付けたリング状のツバ部の両側から押えローラで挟んで支持するため、押えローラに加わる荷重が大きく、保守が面倒で耐久性にも問題があった。 For this reason, the present inventor previously created a double cylindrical screen in which the outer cylindrical screen is integrally formed on the outer periphery of the inner cylindrical screen, and the driven roller on the upper side of the inclined base and the motor on the lower side. Two connected drive rollers are attached to each of them, and a double cylindrical screen is rotatably supported on them, and ring-shaped flanges are provided on the outer periphery of the double cylinder screen, and on both sides of the flanges. A double trommel with a presser roller attached to prevent the double cylindrical screen from moving was developed. However, since a heavy double cylindrical screen is supported by holding the presser roller from both sides of the ring-shaped collar attached to the outer periphery, the load applied to the presser roller is large, making maintenance cumbersome and causing problems with durability. there were.
本発明は上記問題を改善し、内側円筒スクリーンの外側に外側円筒スクリーンを一体に設けて二重にして、モータの駆動軸に直結して回転させることにより、被選別材を３種類の大きさに効率よく選別することができると共に、長手方向を短くして装置を小型、軽量化し、基礎工事や製造コストを安くすることができると共に、内側円筒スクリーンを構成する多孔板の透過孔に詰まった被選別材を掻き取って目詰まりを防止できる二重トロンメルを提供するものである。 The present invention improves the above problem, and the outer cylindrical screen is integrally provided outside the inner cylindrical screen to be doubled, and is directly connected to the drive shaft of the motor to be rotated, so that the material to be sorted can be divided into three sizes. In addition to reducing the length and length of the device, the construction and manufacturing costs can be reduced, and the perforation of the perforated plate that forms the inner cylindrical screen is clogged. A double trommel capable of preventing clogging by scraping the material to be sorted is provided.
本発明の請求項１記載の二重トロンメルは、籠状内側円筒フレームの中間部に、多数の透過孔を開孔した多孔板を巻回して内側円筒スクリーンを形成し、前記籠状内側円筒フレームを囲むように間隔をおいて籠状外側円筒フレームを取付け、ここに前記透過孔より篩目の小さい多数の透過孔を開孔した多孔板を巻回して外側円筒スクリーンを形成し、前記籠状内側円筒フレームの中心に、モータに接続した駆動軸を挿着して、駆動軸に取付けた連結板を介して籠状内側円筒フレームに接続し、内側円筒スクリーンの一端側の開口部を投入口とし、他端側の開口部を第１の排出口とし、外側円筒スクリーンの前記第１の排出口側のリング状開口部を第２の排出口とした二重円筒スクリーンを形成し、この二重円筒スクリーンを傾斜した基台の上方側に設けた左右の支持ローラで回転自在に支持し、更に前記駆動軸が貫通する開口部を形成した取付板に、駆動軸を跨がるように複数個のローラを取付け、この取付板を駆動軸の軸方向に沿って間隔をおいて配置すると共に、この取付板にアームを介してその先端に、内側円筒スクリーンの内周に端部が摺接する掻き取り板を取付けて目詰まり防止装置を形成し、この目詰まり防止装置の取付板を、駆動軸を跨がるように取付けてローラを駆動軸の外周に転動させて揺動自在に支持し、内側円筒スクリーンの多孔板の透過孔に詰まったカスを、目詰まり防止装置の掻き取り板で掻き取るようにしたことを特徴とするものである。 In the double trommel according to claim 1 of the present invention, an inner cylindrical screen is formed by winding a perforated plate having a large number of perforated holes in the middle of the bowl-shaped inner cylindrical frame, A cylindrical outer cylindrical frame is attached so as to surround the outer peripheral screen, and an outer cylindrical screen is formed by winding a perforated plate having a large number of transmission holes smaller in size than the transmission holes. A drive shaft connected to the motor is inserted into the center of the inner cylindrical frame, connected to the bowl-shaped inner cylindrical frame via a connecting plate attached to the drive shaft, and an opening on one end side of the inner cylindrical screen is inserted. A double cylindrical screen is formed in which the opening on the other end side is the first discharge port, and the ring-shaped opening on the first discharge port side of the outer cylindrical screen is the second discharge port. On a base with a slanted cylindrical screen Rotatably supported by the support rollers of the right and left provided on the side, further to a mounting plate forming an opening in which the drive shaft passes, mounting a plurality of rollers so as to extend over the drive shaft, the mounting plate A clogging prevention device is provided by arranging a scraping plate whose end is in sliding contact with the inner periphery of the inner cylindrical screen at the tip of the mounting plate via an arm, and arranged at intervals along the axial direction of the drive shaft. The clogging prevention device mounting plate is mounted so as to straddle the drive shaft, and the roller is slidably supported on the outer periphery of the drive shaft. The waste clogged in the hole is scraped off by a scraping plate of the clogging prevention device .
本発明の請求項２記載の二重トロンメルは、請求項１に更に、取付板の連結板と対向する側面に移動防止ローラを取付け、連結板に駆動軸を囲むようにリング状のローラ受板を取付け、前記移動防止ローラがローラ受板を転動して、目詰まり防止装置の軸方向への移動を防止したことを特徴とするものである。 The double trommel according to a second aspect of the present invention is the ring-shaped roller receiving plate according to the first aspect, wherein a movement preventing roller is attached to a side surface of the mounting plate facing the connecting plate, and the drive shaft is surrounded by the connecting plate.

また図３に示すように二重円筒スクリーン２の外側円筒スクリーン４の左右両側と下方を囲むようにＶ形のシュート３３が取付けられている。また図１に示すように、前記投入口２１には図示しないチョッパーで細かく切削された木材チップ３５を二重円筒スクリーン２の内側円筒スクリーン３内に搬入する搬入ベルトコンベア３８の先端が挿入されている。また第１の排出口２２の前方にはオーバーサイズのチップ３５Ａを捕集する搬出ベルトコンベア３９Ａが設けられ、また第２の排出口２３の前方には適合サイズのチップ３５Ｂを捕集する搬出ベルトコンベア３９Ｂが設けられ、更に外側円筒スクリーン４を囲むシュート３３の下方にはダスト４０を捕集する搬出ベルトコンベア３９Ｃが設けられている。 Further, as shown in FIG. 3, a V-shaped chute 33 is attached so as to surround the left and right sides and the lower side of the outer cylindrical screen 4 of the double cylindrical screen 2. As shown in FIG. 1, the leading end of a carry-in belt conveyor 38 for carrying a wood chip 35 finely cut by a chopper (not shown) into the inner cylindrical screen 3 of the double cylindrical screen 2 is inserted into the insertion port 21. Yes. Further, a carry-out belt conveyor 39A for collecting oversized chips 35A is provided in front of the first discharge port 22, and a carry-out belt for collecting suitable size chips 35B in front of the second discharge port 23. conveyor 3 9B is provided further below the chute 33 which surrounds the outer cylindrical screen 4 and discharge belt conveyor 39C is provided for collecting the dust 40.
更に駆動軸２５に目詰まり防止装置４２が取付けられている。この目詰まり防止装置４２は、図５に示すように開口部４３を形成した鍵形の取付板４４に、駆動軸２５を跨がるように左右２個のローラ４５と下部に１個のローラ４５を取付けたものである。この開口部４３の内径は、駆動軸２５の外径よりやや大きく形成され、ここに左右のローラ４５を駆動軸２５の上部側に跨がるように取付けたものである。 Further, a clogging prevention device 42 is attached to the drive shaft 25. As shown in FIG. 5 , the clogging prevention device 42 has a key-shaped mounting plate 44 having an opening 43 formed thereon, two left and right rollers 45 so as to straddle the drive shaft 25, and one roller at the bottom. 45 is attached. The inner diameter of the opening 43 is formed to be slightly larger than the outer diameter of the drive shaft 25, and the left and right rollers 45 are attached so as to straddle the upper side of the drive shaft 25.
駆動軸２５と籠状内側円筒フレーム９を接続する放射状に取付けた連結板２６、２６の対向する側面には図４および図６に示すように駆動軸２５を囲むようにリング状のローラ受板４６が取付けられている。また前記取付板４４の、ローラ受板４６と対向する側面の上部には図６に示すように、ローラ受板４６の側面を転動する移動防止ローラ４７が水平に取付けられている。 As shown in FIGS. 4 and 6 , ring-shaped roller receiving plates are provided on opposite side surfaces of the connecting plates 26, 26 that are radially attached to connect the drive shaft 25 and the bowl-shaped inner cylindrical frame 9. 46 is attached. Further, as shown in FIG. 6 , a movement preventing roller 47 that rolls on the side surface of the roller receiving plate 46 is horizontally attached to the upper portion of the mounting plate 44 that faces the roller receiving plate 46.
この鍵形の取付板４４は図４に示すように駆動軸２５の軸方向に沿って間隔をおいて２個配置し、この下部に図５に示すように２本のアーム４８、４９が取付けられている。このアーム４８は取付板４４に固定され、上方側と下方側のアーム４８、４８の間には板状の左右バランスウエイト５１が接続されている。また他方のアーム４９は、図５に示すようにアーム４８の他端に軸５２で回動自在に支持され、その先端にアングル材と平板とを組み合わせた掻き取り板５３が取付けられ、内側円筒スクリーン３の内周に摺接するようになっている。 Mounting plate 44 of the key form two arranged at intervals along the axial direction of the drive shaft 25 as shown in FIG. 4, two arms 48 and 49 as shown in FIG. 5 to the bottom attachment It has been. The arm 48 is fixed to the mounting plate 44, and a plate-like left and right balance weight 51 is connected between the upper and lower arms 48, 48. The other arm 49 is rotatably supported by a shaft 52 at the other end of the arm 48 , as shown in FIG. 5, and a scraping plate 53 in which an angle material and a flat plate are combined is attached to the tip of the other arm 49 . It is in sliding contact with the inner periphery of the screen 3.
上記構成の二重トロンメルは図１に示すように、ギアードモータ２９に接続した駆動軸２５が回転すると、これに連結された二重円筒スクリーン２が上方側の支持ローラ３１に支持されて図３の矢印方向に回転する。この状態で被選別材となるチョッパーで細かく切削された木材チップ３５を内側円筒スクリーン３の上方側に形成した投入口２１から搬入ベルトコンベア３８で搬入する。 1, when the drive shaft 25 connected to the geared motor 29 is rotated, the double cylindrical screen 2 connected thereto is supported by the upper support roller 31 as shown in FIG. Rotate in the direction of the arrow. In this state, the wood chip 35 finely cut by the chopper as the material to be selected is carried by the carry-in belt conveyor 38 from the loading port 21 formed on the upper side of the inner cylindrical screen 3.
このように二重円筒スクリーン２が回転しているので、内部に投入された木材チップ３５も回転しながら内側円筒スクリーン３内を下降し、図１に示すように多孔板１０Ｂの篩目の大きな透過孔１０Ａで選別されて、適合サイズのチップ３５Ｂとダスト４０が通過し、オーバーサイズのチップ３５Ａはそのまま下降して第１の排出口２２から搬出ベルトコンベア３９Ａで外部に排出される。 Since the double cylindrical screen 2 rotates in this way, the wood chip 35 thrown into the inside also descends while rotating inside the inner cylindrical screen 3, and as shown in FIG. The suitable size chips 35B and the dust 40 pass through the through holes 10A, and the oversized chips 35A are lowered as they are and discharged to the outside from the first discharge port 22 by the carry-out belt conveyor 39A.
また内側円筒スクリーン３を通過した適合サイズのチップ３５Ｂとダスト４０は、この外側に設けた外側円筒スクリーン４に落下して、更に回転しながら多孔板１７Ｂの篩目の小さな透過孔１７Ａで選別されて、ダスト４０だけが通過する。このダスト４０は図３に示すように、Ｖ形のシュート３３に案内されて落下し、搬出ベルトコンベア３９Ｃで外部に搬出される。また外側円筒スクリーン４内に残った適合サイズのチップ３５Ｂはそのまま下降し第２の排出口２３から搬出ベルトコンベア３９Ｂで外部に排出される。 Further, the chip 35B and the dust 40 of the appropriate size that have passed through the inner cylindrical screen 3 fall on the outer cylindrical screen 4 provided outside this, and are further sorted by the small permeation holes 17A of the perforated plate 17B while rotating. Thus, only dust 40 passes. As shown in FIG. 3, the dust 40 is guided by a V-shaped chute 33 and dropped, and is carried out to the outside by a carry-out belt conveyor 39C. Further, the chip 35B of the appropriate size remaining in the outer cylindrical screen 4 is lowered as it is and discharged to the outside from the second discharge port 23 by the carry-out belt conveyor 39B.
この場合、図３に示すように先ず内側円筒スクリーン３で、オーバーサイズのチップ３５Ａを選別してから、外側円筒スクリーン４でダスト４０の混在した適合サイズのチップ３５Ｂを選別するので、従来のようにオーバーサイズのチップ３５Ａが混ざった状態でダスト４０を除去する方法に比べてダスト４０の選別効率が優れている。 In this case, as shown in FIG. 3, first, the oversized chip 35A is sorted by the inner cylindrical screen 3, and then the suitable size chip 35B in which the dust 40 is mixed is sorted by the outer cylindrical screen 4. As compared with the method of removing the dust 40 in a state where the oversized chips 35A are mixed, the dust 40 sorting efficiency is superior.
しかも外径の大きな外側円筒スクリーン４で選別するので周速度が大きく、ダスト４０の混在した適合サイズのチップ３５Ｂは内周面に沿って高く持ち上げられて落下し、回転する内側円筒スクリーン３の外周や外側円筒スクリーン４の内側底面に叩き付けるように落下するので、混在しているダスト４０が更に効率よく除去される。この結果、ダスト含有率の少ない販売価格の高い適合サイズのチップ３５Ｂを得ることができる。 Moreover, since the outer cylindrical screen 4 having a larger outer diameter is selected, the peripheral speed is high, and the suitable size chip 35B mixed with the dust 40 is lifted and dropped along the inner peripheral surface, and the outer periphery of the rotating inner cylindrical screen 3 is rotated. Moreover, since it falls so that it may hit against the inner bottom face of the outer cylindrical screen 4, the mixed dust 40 is removed more efficiently. As a result, it is possible to obtain a chip 35B of a suitable size with a low dust content and a high selling price.
更に目詰まり防止装置４２は、二重円筒スクリーン２が回転すると木材チップ３５が内側円筒スクリーン３内で回転しながら篩い分けされる。この過程で多孔板１０Ｂの透過孔１０Ａに、この内径とほぼ等しい大きさの木材チップ３５が詰まることがある。この状態で駆動軸２５に揺動自在に支持させた目詰まり防止装置４２の掻き取り板５３が図５に示すように多孔板１０Ｂに揺動しながら摺接して、透過孔１０Ａに詰まった木材チップ３５を掻き取って目詰まりを防止することができる。 Further, the clogging prevention device 42 is sieved while the wood chip 35 is rotated in the inner cylindrical screen 3 when the double cylindrical screen 2 rotates. In this process, the wood chip 35 having a size substantially equal to the inner diameter may be clogged in the transmission hole 10A of the porous plate 10B. In this state, the scraping plate 53 of the clogging prevention device 42 supported swingably on the drive shaft 25 is in sliding contact with the perforated plate 10B while swinging to the perforated plate 10B as shown in FIG. The chip 35 can be scraped off to prevent clogging.
この場合、アーム４８の先端に取付けた左右バランスウエイト５１により、アーム４９の先端に取付けた掻き取り板５３がバランスして取付板４４の揺動を少なくすることができると共に、アーム４９は軸５２で回動自在に支持されているので内側円筒スクリーン３の回転に伴って上下に移動することができる。従って目詰まり防止装置４２は駆動軸２５を跨がるように揺動自在に取付けられ、駆動軸２５の回転とは別個に揺動しながら掻き取り板５３で透過孔１０Ａに詰まった木材チップ３５を除去するので、効率よく掻き取ることができる。 In this case, the left and right balance weight 51 attached to the tip of the arm 48 balances the scraping plate 53 attached to the tip of the arm 49 so that the swing of the attachment plate 44 can be reduced. And can be moved up and down with the rotation of the inner cylindrical screen 3. Therefore, the clogging prevention device 42 is swingably attached so as to straddle the drive shaft 25, and the wood chip 35 clogged in the transmission hole 10A by the scraping plate 53 while swinging separately from the rotation of the drive shaft 25. Can be efficiently scraped off.
またこの目詰まり防止装置４２は図５に示すように、取付板４４の側面に移動防止ローラ４７が水平に取付けられ、これがローラ受板４６の上部側面を転動し、また投入口２１側の取付板４４にも同様に移動防止ローラ４７が取付けられているので、傾斜した目詰まり防止装置４２が軸方向に沿って下降するのを防止することができる。 Further , as shown in FIG. 5, the clogging prevention device 42 has a movement prevention roller 47 mounted horizontally on the side surface of the mounting plate 44, which rolls on the upper side surface of the roller receiving plate 46, and also on the side of the insertion port 21. Since the movement prevention roller 47 is similarly attached to the attachment plate 44, the inclined clogging prevention device 42 can be prevented from descending along the axial direction.
また回転する二重円筒スクリーン２は図１に示すように、二重円筒スクリーン２に接続した駆動軸２５が軸受２７で支持されていると共に、二重円筒スクリーン２の上方側が支持ローラ３１で回転自在に支持されているので、横置きに傾斜して配置した二重円筒スクリーン２は移動することなく安定した回転が行なえ、保守が容易で耐久性に優れている。 As shown in FIG. 1, the rotating double cylindrical screen 2 has a drive shaft 25 connected to the double cylindrical screen 2 supported by a bearing 27 and an upper side of the double cylindrical screen 2 rotated by a support roller 31. Since it is supported freely, the double cylindrical screen 2 arranged in a horizontally inclined manner can rotate stably without moving, is easy to maintain and has excellent durability.
図７は本発明の異なる他の実施の形態を示すものである。この目詰まり防止装置４２は、駆動軸２５が貫通する開口部４３を形成した鍵形の取付板４４の左右にアーム４８Ａ、４８Ｂを突設し、上部側と下部側の上下のアーム４８Ａ、４８Ａの間に左右バランスウエイト５１を取付け、アーム４８Ｂの先端に軸５２でアーム４９を回動自在に支持し、この上部側と下部側の先端にアングル材と平板とを組み合わせた掻き取り板５３を取付けたものである。また鍵形の取付板４４の下方に突出した部分の下部には垂直バランスウエイト５４が取付けられている。 FIG. 7 shows another embodiment of the present invention. The clogging prevention device 42 has arms 48A and 48B protruding from the left and right sides of a key-shaped mounting plate 44 having an opening 43 through which the drive shaft 25 passes, and upper and lower arms 48A and 48A on the upper side and the lower side. The left and right balance weights 51 are attached to the arm 48B. The arm 49 is rotatably supported by the shaft 52 at the tip of the arm 48B. It is attached. A vertical balance weight 54 is attached to the lower part of the portion protruding downward from the key-shaped attachment plate 44.
これはアーム４９が短いので内側円筒スクリーン３内を移動する木材チップ３５との接触を少なくすることができる。また取付板４４の水平方向のバランス調整は左右バランスウエイト５１で行ない、垂直方向のバランス調整は鍵形の下方に突出した部分に垂直バランスウエイト５４が取付けられているので、取付板４４の垂直な状態を極力保持して安定した掻き取り作業を行なうことができる。また二重円筒スクリーン２を逆回転して使用する場合にはアーム４８Ｂに左右バランスウエイト５１を取付け、アーム４８Ａの先端に軸５２でアーム４９を回動自在に支持し、この先端に掻き取り板５３を取付ければ良い。 Since the arm 49 is short, the contact with the wood chip 35 moving in the inner cylindrical screen 3 can be reduced. Further, the horizontal balance adjustment of the mounting plate 44 is performed by the left and right balance weights 51, and the vertical balance adjustment is performed by the vertical balance weight 54 at the portion protruding downward from the key shape. A stable scraping operation can be performed while maintaining the state as much as possible. When the double cylindrical screen 2 is used in reverse rotation, the left and right balance weights 51 are attached to the arm 48B, the arm 49 is rotatably supported by the shaft 52 at the tip of the arm 48A, and the scraping plate is attached to the tip. 53 may be attached.
なお上記説明では多孔板１０Ｂ、１７Ｂとして円形の透過孔１０Ａ、１７Ｂを打ち抜いた打ち抜き板を用いた場合について示したが、四角や多角形でも良く、またラス材を用いても良い。 In the above description, the perforated plates 10B and 17B are shown as punched plates with punched circular transmission holes 10A and 17B. However, a square or polygonal shape or a lath material may be used.
なお本発明の二重トロンメルは木材の樹皮やチップの選別に限らず、粉体や、砂利、粉砕した産業廃棄物などの選別にも広く使用することができる。 The double trommel of the present invention can be widely used not only for sorting bark and chips of wood, but also for sorting powder, gravel, crushed industrial waste and the like.
