Description

本発明は、例えば砂、焼却灰、鉱石、粘性土などの粘着性のある粉粒体を搬送するための搬送装置に関するものである。   The present invention relates to a transport device for transporting adhesive powder particles such as sand, incineration ash, ore, and clay.

この種の搬送装置として、搬送チエンにスクレーパなどの搬送板を取り付け、この搬送板を筒体内に沿って案内しながら進行させることにより、粘着性のある粉粒体を所定の排出位置にまで搬送するようにしたものがある(特許文献1)。
特開平11―240607号公報
As this kind of transport device, a transport plate such as a scraper is attached to the transport chain, and the transport plate is advanced while being guided along the cylinder, thereby transporting the sticky granular material to a predetermined discharge position. There is one which is made to do (patent document 1).
JP-A-11-240607

しかし、以上の搬送装置では、搬送板に粉粒体の一部やその微粒物質などの付着物が付着しやすい。このように搬送板に付着物が付着すると、搬送効率の低下を招く。   However, in the above conveying apparatus, deposits such as a part of the granular material and its fine particles are likely to adhere to the conveying plate. Thus, when an adhering substance adheres to a conveyance board, the fall of conveyance efficiency will be caused.

そこで、搬送板の付着物を掻き落すために、図6及び図7に示す掻き落し装置が用いられている。図6に示す掻き落し装置は、スプロケットSRに搬送チエンCHを掛回し、このチエンCHに複数の搬送板Cを連結してなる搬送装置において、この搬送装置の排出側近くで搬送板Cの進行方向前方にクリーナ板CBを軸杆Sを中心に前後揺動可能に取り付けるとともに、このクリーナ板CBをコイルスプリングCSにより先端が搬送板Cの進行方向後方を常時指向するように付勢させる。そして、付着物SMが付着した搬送板Cが矢印F方向に進行されながら搬送装置の排出側近くに至ったとき、クリーナ板CBの先端が搬送板Cの進行方向前面で上方位置に当たり、この搬送板Cの進行に伴いクリーナ板CBの先端が搬送板Cの前面に押し当てられた状態で、クリーナ板CBがコイルスプリングCSに抗して軸杆Sを中心に進行方向前方に揺動しながら前面下方側へと移行し、このときにクリーナ板CBの先端により搬送板Cに付着した付着物SMが掻き落される。この後クリーナ板CBは、付着物SMが掻き落とされた搬送板Cを後方側へと乗り越え、コイルスプリングCSの引張力により再度次に移行してくる搬送板Cの進行方向前面で上方位置に対向して前記と同様の作用を繰り返す。   Therefore, a scraping device shown in FIGS. 6 and 7 is used in order to scrape off deposits on the transport plate. The scraping device shown in FIG. 6 is a transfer device in which a transfer chain CH is wound around a sprocket SR, and a plurality of transfer plates C are connected to the chain CH, and the transfer plate C advances near the discharge side of the transfer device. The cleaner plate CB is attached to the front in the direction so as to be able to swing back and forth about the shaft rod S, and the cleaner plate CB is urged by a coil spring CS so that the front end is always directed rearward in the traveling direction of the transport plate C. When the transport plate C to which the deposit SM is attached reaches the discharge side of the transport device while proceeding in the direction of arrow F, the tip of the cleaner plate CB hits the upper position on the front in the travel direction of the transport plate C. With the tip of the cleaner plate CB pressed against the front surface of the transport plate C as the plate C advances, the cleaner plate CB swings forward in the direction of travel around the shaft rod S against the coil spring CS. At this time, the deposit SM adhered to the transport plate C is scraped off by the tip of the cleaner plate CB. After this, the cleaner plate CB moves over the transport plate C from which the deposit SM has been scraped off to the rear side, and is moved to the upper position in the front of the transport plate C in the advancing direction again by the tensile force of the coil spring CS. Oppositely, the same operation as described above is repeated.

また、図7に示す掻き落し装置は、搬送装置の排出側近くに半円弧状に湾曲したクリーナ板CBを軸杆Sを中心に揺動可能に取り付けている。このクリーナ板CBは、その湾曲先端がチエンCHを掛回するスプロケットSRのほぼ真下に至った搬送板Cの進行方向前面側を常時指向するようにコイルスプリングCSを介して支持される。付着物SMが付着した搬送板Cが、前記図6の場合とは逆の矢印R方向に進行しながら搬送装置の排出側近くに至ったとき、クリーナ板CBの先端が搬送板Cの進行方向前面で上方位置に当たり、この搬送板Cの進行に伴いクリーナ板CBの先端が搬送板Cの前面に押し当てられた状態で、クリーナ板CBがコイルスプリングCSに抗して軸杆Sを中心に進行方向前方に揺動しながら前面下方側へと移行し、このときにクリーナ板CBの先端により搬送板Cに付着した付着物SMが掻き落される。この後クリーナ板CBは、付着物SMが掻き落とされた搬送板Cを進行方向後方へと乗り越え、スプリングCSの引張力により再度次に移行してくる搬送板Cの進行方向前面で上方位置に対向して前記と同様の作用を繰り返す。   Further, in the scraping device shown in FIG. 7, a cleaner plate CB curved in a semicircular arc shape is attached near the discharge side of the conveying device so as to be swingable about a shaft S. This cleaner plate CB is supported via a coil spring CS so that its curved tip always points to the front side in the direction of travel of the conveying plate C, which is almost directly below the sprocket SR that hangs the chain CH. When the conveying plate C to which the deposit SM has adhered reaches the discharge side of the conveying device while moving in the direction of the arrow R opposite to the case of FIG. 6, the tip of the cleaner plate CB is the traveling direction of the conveying plate C The cleaner plate CB hits the upper position on the front surface, and the cleaner plate CB is pressed against the coil spring CS with the tip of the cleaner plate CB pressed against the front surface of the transfer plate C as the transport plate C advances. While moving forward in the advancing direction, the movement proceeds to the lower front side, and at this time, the deposit SM adhered to the conveying plate C is scraped off by the tip of the cleaner plate CB. After this, the cleaner plate CB moves over the transport plate C from which the deposit SM has been scraped off to the rear in the traveling direction, and is moved to the upper position on the front surface in the traveling direction of the transport plate C, which is moved again by the tensile force of the spring CS. Oppositely, the same operation as described above is repeated.

ところが、以上の各装置では、搬送板Cの付着物SMが掻き落された後に、クリーナ板CBは搬送板Cを乗り越え、コイルスプリングCSの引張力により次に移行してくる搬送板Cの進行方向前面に衝突されるため、そのときの衝撃音が大きく、特に搬送板Cに付着する付着物SMが少ないときに衝撃音は非常に大きくなる。   However, in each of the above devices, after the deposit SM on the conveying plate C is scraped off, the cleaner plate CB gets over the conveying plate C, and the transfer plate C proceeds next by the tensile force of the coil spring CS. The impact sound at that time is large because it collides with the front surface in the direction, and particularly when there is little deposit SM adhering to the transport plate C, the impact sound becomes very large.

そこで、本発明は、運転音が静かで搬送板に付着する付着物を確実に掻き落すことができる粉粒体搬送装置を提供することを目的としている。   SUMMARY OF THE INVENTION An object of the present invention is to provide a granular material conveying device that can quietly scrape off deposits that are quiet in operation noise and adhere to a conveying plate.

上記目的を達成するために、本発明は、粉粒体の投入位置から排出位置まで延設された筒体と、この筒体の内部を進行して粉粒体を搬送する搬送板を備えた粉粒体搬送装置であって、前記筒体の内部で排出位置近くに、搬送板と同期して回転し、この搬送板に付着した付着物を掻き落す掻き落し装置が設けられている。   In order to achieve the above object, the present invention includes a cylindrical body extending from the charging position to the discharging position of the granular material, and a transport plate that travels through the cylindrical body and transports the granular material. There is provided a scraping device that rotates in synchronization with the transport plate and scrapes the adhering matter attached to the transport plate near the discharge position inside the cylindrical body.

搬送板で搬送される粉粒体が排出側近くに至ったとき、この搬送板と同期して回転する掻き落し装置により、搬送板に付着している付着物が確実に掻き落される。このように掻き落し装置の回転によって搬送板の付着物を掻き落すことにより、従来のように衝突音がなくなって、粉粒体の静粛な搬送が行える。   When the granular material conveyed by the conveying plate reaches near the discharge side, the adhering material adhering to the conveying plate is surely scraped off by the scraping device that rotates in synchronization with the conveying plate. In this way, by scraping off the deposits on the conveying plate by the rotation of the scraping device, there is no collision sound as in the conventional case, and the granular material can be conveyed silently.

この発明の好ましい実施形態では、前記掻き落し装置が、複数の回転羽根と、これを駆動する駆動機構とからなり、この駆動機構は、搬送板が粉粒体を排出した後、搬送板の進行方向前面の上方位置に回転羽根の先端が接触して押し当てられ、この押し当てられた状態で搬送板の進行に伴い回転羽根の先端が搬送板の下方側に移行するように、搬送板の進行と回転羽根の回転とを同期して行う。この構成によれば、前記搬送体による粉粒体の排出後に、回転羽根の先端が搬送板の上方位置に接触して押し当てられ、この押し当てられた状態で搬送板の進行に伴い回転羽根の先端が搬送板の下方側へと移行されるため、搬送板に付着した付着物が回転羽根により搬送板の上部から下部までの全面にわたって確実に掻き落される。   In a preferred embodiment of the present invention, the scraping device includes a plurality of rotating blades and a driving mechanism that drives the rotating blades, and the driving mechanism advances the conveying plate after the conveying plate discharges the granular material. The tip of the rotating blade contacts and is pressed against the upper position of the direction front, and the tip of the rotating blade moves to the lower side of the conveying plate as the conveying plate advances in this pressed state. Progression and rotation of the rotating blades are performed in synchronization. According to this configuration, after discharging the granular material by the transport body, the tip of the rotary blade comes into contact with the upper position of the transport plate and is pressed against the rotary plate as the transport plate advances in this pressed state. Since the tip of the transfer plate moves to the lower side of the conveyance plate, the adhering matter adhering to the conveyance plate is surely scraped off by the rotating blades from the upper part to the lower part of the conveyance plate.

また、この発明の好ましい実施形態では、前記搬送板の進行方向に対し回転羽根が同方向に回転される。この構成によれば、搬送体に付着した付着物が回転羽根による叩き落とし作用と掻き落し作用との2つの作用で確実に掻き落される。   Moreover, in preferable embodiment of this invention, a rotary blade is rotated in the same direction with respect to the advancing direction of the said conveyance board. According to this configuration, the adhering matter adhering to the transport body is surely scraped off by the two actions of the hitting action and the scraping action by the rotating blades.

さらに、この発明の好ましい実施形態では、前記掻き落し装置の駆動機構が搬送板を駆動する駆動源に連動されている。この構成によれば、搬送板の駆動源で掻き落し装置の駆動が行えるので、全体構成が簡素化される。   Furthermore, in a preferred embodiment of the present invention, the drive mechanism of the scraping device is linked to a drive source that drives the transport plate. According to this configuration, since the scraping device can be driven by the drive source of the transport plate, the overall configuration is simplified.

以上の粉粒体搬送装置によれば、運転音を静粛としながら搬送板に付着する付着物を確実に掻き落すことができる。   According to the above granular material conveying apparatus, the adhering matter adhering to the conveying plate can be surely scraped off while the operation sound is quiet.

以下、本発明にかかる粉粒体搬送装置を図面に基づいて説明する。図1は本発明の一実施形態にかかる搬送装置の一部を切り欠いて示す側面図である。この粉粒体搬送装置Tは、低位置から所定の高さ位置にまで粉粒体をほぼ垂直に搬送するものであって、低位置に粉粒体の投入ホッパ1aを備えた供給部1が、高位置に吐出ホッパ2aを備えた排出部2が設けられ、これら供給部1と排出部2の間に中間搬送部3が形成されている。前記供給部1と排出部2及び中間搬送部3には、供給部1のホッパ1aに投入された粉粒体Pを排出部2まで搬送して吐出ホッパ2aから排出する搬送機構4が設けられている。   Hereinafter, the granular material conveying apparatus concerning this invention is demonstrated based on drawing. FIG. 1 is a side view showing a part of a conveying apparatus according to an embodiment of the present invention. The granular material conveying device T conveys the granular material almost vertically from a low position to a predetermined height position, and a supply unit 1 having a granular material input hopper 1a at a low position is provided.

この搬送機構4は、前記投入ホッパ1aと吐出ホッパ2aとの間に延設された筒体41と、この筒体41の内部で吐出ホッパ2a側に設けられた左右一対の駆動スプロケット42と、筒体41の内部で投入ホッパ1a側に設けられた左右一対の従動スプロケット43及びこれら各スプロケット42,43の間に配置された複数対の中間スプロケット44と、これら各スプロケット42〜44に掛回された平行な2条の搬送チエン45と、このチエン45の間に連結されて一体に進行する多数の搬送板46と、前記筒体41の内部で投入ホッパ1aと吐出ホッパ2aの範囲にわたり搬送板46に沿って配設されたガイド47とにより構成されている。また、前記吐出ホッパ2aの近くの筒体41上には、減速機48aを備えた駆動モータ48が取り付けられ、このモータ48の駆動で前記チエン45を回行させることにより、前記投入ホッパ1aに投入された粉粒体Pを前記チエン45と一体に進行する搬送板46により、前記ガイド47とその周囲の筒体41に沿って排出部2にまで搬送させる。   The transport mechanism 4 includes a cylinder 41 extending between the charging hopper 1a and the discharge hopper 2a, a pair of left and right drive sprockets 42 provided on the discharge hopper 2a side inside the cylinder 41, A pair of left and right driven sprockets 43 provided on the charging hopper 1a side inside the cylinder body 41, a plurality of pairs of intermediate sprockets 44 disposed between the sprockets 42 and 43, and the sprockets 42 to 44 are hung around.

By rotating the chain 45 by driving the motor 48, the charging hopper 1a The charged granular material P is transported to the discharge unit 2 along the guide 47 and the surrounding cylindrical body 41 by the transport plate 46 that travels integrally with the chain 45.

図2は粉粒体搬送装置Tの排出部2を拡大して示す側断面図、図3は図2のX−X線方向から見た正断面図、図4は図2のY−Y線方向から見た正断面図である。前記搬送板46は、図4のように、正面視6角形状に形成され、この搬送板46の左右両側がシャックル49を介して2条の搬送チエン45にそれぞれ連結されている。また、前記吐出ホッパ2aの上方側で筒体41の内部には、前記搬送板46に付着した付着物SMを掻き落す掻き落し装置5が設けられている。   2 is an enlarged side sectional view showing the discharge unit 2 of the granular material conveying device T, FIG. 3 is a front sectional view as seen from the XX line direction of FIG. 2, and FIG. 4 is a YY line of FIG. It is the front sectional view seen from the direction. As shown in FIG. 4, the transport plate 46 is formed in a hexagonal shape when viewed from the front, and both left and right sides of the transport plate 46 are connected to two transport chains 45 via shackles 49. Further, a scraping device 5 for scraping off the deposit SM adhering to the transport plate 46 is provided in the cylinder 41 above the discharge hopper 2a.

この掻き落し装置5は、図2のように、前記搬送チエン45の排出端近くの上部に設けられたれた複数枚の回転羽根51と、これを駆動する駆動機構52とからなり、この駆動機構52は、前記搬送板46が搬送チエン45の排出端近くに至ったとき、この搬送板46の進行方向前面の上方位置に回転羽根51の先端が接触して押し当てられ、この押し当てられた状態で搬送板46の進行に伴い回転羽根51の先端が搬送板46の下方側に移行するように、搬送板46の進行と回転羽根51の回転が同期して行われるように設定されている。   As shown in FIG. 2, the scraping device 5 includes a plurality of rotating blades 51 provided at an upper portion near the discharge end of the transport chain 45 and a driving mechanism 52 for driving the rotating blades 51. 52, when the transport plate 46 comes close to the discharge end of the transport chain 45, the tip of the rotary blade 51 comes into contact with the upper position of the front surface of the transport plate 46 in the direction of travel and is pressed. In this state, it is set so that the advance of the transport plate 46 and the rotation of the rotary blade 51 are performed in synchronization so that the tip of the rotary blade 51 moves to the lower side of the transport plate 46 as the transport plate 46 advances. .

具体的に説明すると、前記駆動機構52は、図2,3のように、前記駆動スプロケット42を支持する駆動軸40の一端に設けられた第1伝動スプロケット53と、前記回転羽根51を支持する回転軸50の近くに設けられた支持軸60に、第1伝動スプロケット53と対向状に支持された第2伝動スプロケット54と、これら第1,第2伝動スプロケット53,54の間に掛回される伝動チエン55と、前記第2伝動スプロケット54の支持軸60に支持された第1スパーギヤ56と、前記回転羽根51の回転軸50に支持され、前記第1スパーギヤ56と常時噛合う第2スパーギヤ57とで構成される。そして、前記駆動スプロケット42の回転に伴い第1伝動スプロケット53、伝動チエン55、第2伝動スプロケット54、第1スパーギヤ56、第2スパーギヤ57、回転軸50を介して、前記回転羽根51を搬送板46の進行方向Z1と同一向きのZ2方向に回転させる。   More specifically, the drive mechanism 52 supports the first transmission sprocket 53 provided at one end of the drive shaft 40 that supports the drive sprocket 42 and the rotary blade 51 as shown in FIGS. A support shaft 60 provided near the rotating shaft 50 is hung between a second transmission sprocket 54 supported opposite to the first transmission sprocket 53 and the first and second transmission sprockets 53, 54. Transmission chain 55, a first spur gear 56 supported by the support shaft 60 of the second transmission sprocket 54, and a second spur gear supported by the rotation shaft 50 of the rotary blade 51 and always meshing with the first spur gear 56. 57. As the drive sprocket 42 rotates, the rotary blade 51 is transferred to the transport plate via the first transmission sprocket 53, the transmission chain 55, the second transmission sprocket 54, the first spur gear 56, the second spur gear 57, and the rotary shaft 50. 46 is rotated in the Z2 direction, the same direction as the traveling direction Z1.

また、前記回転羽根51の駆動機構52は、前記搬送機構4と連動され、この搬送機構4と同一の駆動源によって駆動される。具体的には、図2,3のように、前記駆動モータ48の減速機48aに取り付けた駆動スプロケット48bと、前記チエン45の駆動スプロケット42を支持する駆動軸40の軸端に前記駆動スプロケット48bと対向状に設けられた従動スプロケット58との間に駆動チエン59を掛回させる。そして、前記駆動モータ48の駆動により前記搬送チエン45に連動して回転羽根51を回転させる。   The drive mechanism 52 of the rotary blade 51 is interlocked with the transport mechanism 4 and is driven by the same drive source as the transport mechanism 4. Specifically, as shown in FIGS. 2 and 3, the drive sprocket 48 b is attached to the shaft end of the drive sprocket 48 b attached to the speed reducer 48 a of the drive motor 48 and the drive sprocket 42 of the chain 45. And a driven sprocket 58 provided opposite to each other. Then, the rotating blade 51 is rotated in conjunction with the transport chain 45 by driving the drive motor 48.

次に、以上の構成とした搬送装置Tを用いて粉粒体Pを搬送するときの動きについて説明する。先ず、粉粒体Pを搬送するときには、供給部1の投入ホッパ1aから粉粒体Pを搬送機構4の筒体41内に投入する。すると、駆動モータ48の駆動に伴い搬送チエン45を介して進行する搬送板46により、筒体41内に投入された粉粒体Pが前記筒体41内のガイド47とその周囲の筒体41に沿って排出部2にまで搬送される。   Next, the movement when transporting the granular material P using the transport device T configured as described above will be described. First, when the granular material P is conveyed, the granular material P is charged into the cylindrical body 41 of the conveying mechanism 4 from the charging hopper 1 a of the supply unit 1. Then, the powder plate P introduced into the cylindrical body 41 is guided by the guide plate 47 in the cylindrical body 41 and the surrounding cylindrical body 41 by the transport plate 46 that travels through the transport chain 45 as the drive motor 48 is driven. Is conveyed to the discharge unit 2 along the line.

そして、搬送板46により粉粒体Pが排出部2まで搬送されて吐出ホッパ2aから下方に排出される。この粉粒体Pを排出した後、搬送板46に付着した付着物SMは、排出部2の近くに配置された掻き落し装置5により、図5のようにして掻き落される。つまり、図5の(a)のように、前記搬送板46の進行方向前面の上方位置に回転羽根51の先端が接触して押し当てられ、この押し当てられた状態で、図5の(b)、(c)及び(d)のように、搬送板46の進行に伴い回転羽根51の先端が搬送板46の下方側に徐々に移行され、この回転羽根51の先端により付着物SMが搬送板46の上部から下部までの全面にわたって削ぎ取られて確実に掻き落される。   And the granular material P is conveyed by the conveyance board 46 to the discharge part 2, and is discharged | emitted below from the discharge hopper 2a. After the powder P is discharged, the deposit SM adhering to the transport plate 46 is scraped off as shown in FIG. 5 by the scraping device 5 disposed near the discharge unit 2. That is, as shown in FIG. 5A, the tip of the rotary blade 51 is brought into contact with and pressed against the upper position of the front surface in the traveling direction of the transport plate 46, and in this pressed state, (b) in FIG. ), (C) and (d), the tip of the rotary blade 51 is gradually shifted to the lower side of the transport plate 46 as the transport plate 46 advances, and the deposit SM is transported by the tip of the rotary blade 51. The entire surface from the upper part to the lower part of the plate 46 is scraped off and reliably scraped off.

以上の回転羽根51による付着物SMの掻き落し時には、従来のような衝突音は発生しないので、粉粒体Pの搬送が静粛に行える。また、回転羽根51により付着物SMを掻き落すとき、この回転羽根51の回転方向Z2と前記搬送板46の進行方向Z1とが同一方向に設定されているので、搬送板46に付着した付着物SMは回転羽根51による叩き落とし作用と掻き落し作用との2つの作用によって確実に掻き落される。さらに、前記掻き落し装置5の駆動機構52は搬送板46を駆動する駆動モータ48に連動されているので、全体構成が簡素化される。このようにして、1つの回転羽根51で1つの搬送板46に付着した付着物SMを掻き落した後には、次に回転してくる回転羽根51が後続する次の搬送板46の前面側に接触して、この搬送板46に付着する付着物SMが同様にして掻き落される。   When the deposit SM is scraped off by the rotary blades 51 as described above, the conventional collision noise is not generated, so that the granular material P can be conveyed quietly. Further, when the deposit SM is scraped off by the rotary blade 51, the rotation direction Z2 of the rotary blade 51 and the traveling direction Z1 of the transport plate 46 are set in the same direction. SM is surely scraped off by two actions, a knocking action and a scraping action by the rotary blade 51. Furthermore, since the drive mechanism 52 of the scraping device 5 is interlocked with the drive motor 48 that drives the transport plate 46, the overall configuration is simplified. Thus, after scraping off the deposit SM adhered to one transport plate 46 by one rotary blade 51, the rotary blade 51 that rotates next is moved to the front side of the next transport plate 46 that follows. The deposit SM that contacts and adheres to the transport plate 46 is scraped off in the same manner.
