Description
【０００１】[0001]
本考案は、復路である下側走行部において、ベルトを、その搬送面が内側とな るように丸めるようにしたベルトコンベヤに関する。 The present invention relates to a belt conveyor in which a belt is rounded in a lower traveling portion which is a return path so that a conveyance surface is an inner side.
【０００２】[0002]
平らな無端ベルトを、往路及び復路とも平らな状態で回走させる型の平ベルト コンベヤは周知であり、また無端ベルトの往路及び復路の始端部及び終端部を除 く中間部分を、円筒状に丸めて回走させるいわゆるパイプコンベヤも公知(例え ば特公昭32−8725号公報、特公昭43−22698号公報、特開昭57−151508号公報)で ある。 A flat belt conveyor of a type in which a flat endless belt is run in a flat state on both the forward and backward paths is well known, and the intermediate portion of the endless belt except for the forward and backward paths is formed into a cylindrical shape. A so-called pipe conveyor that rolls and rolls is also known (for example, Japanese Patent Publication No. 32-8725, Japanese Patent Publication No. 43-22698, and Japanese Patent Publication No. 57-151508).
【０００３】[0003]
平ベルトコンベヤは、復路においては、搬送面が下方を向くので、粉粒物を搬 送する際には、往路において搬送面に付着した粉粒物が、復路においては落下し て飛散し、付近を汚染するおそれがある。 このことは、搬送物が、劇毒物や可燃物である場合、あるいは高価な物質であ る場合には、極力避ける必要がある。 In the flat belt conveyor, the transport surface faces downward on the return path, so when transporting the powder / granular material, the powder / granular material attached to the transport surface on the outward path falls and scatters on the return path. May pollute. This should be avoided as much as possible when the transported product is a poisonous substance, a flammable substance, or an expensive substance.
【０００４】 このような被搬送物の飛散を防止するため、コンベヤ全体をカバーで覆うこと があるが、このような場合、ベルトの復路側において落下した付着物が、カバー の底部に堆積し、ベルトがその堆積物に接して通過するようになって、ベルトの 走行抵抗が大となり、また、堆積物が案内用のローラの軸部分に侵入して、ロー ラの回転不良を招く等の問題点がある。In order to prevent such scattering of the transported object, the entire conveyor may be covered with a cover. In such a case, the deposits that fall on the return path side of the belt are accumulated on the bottom of the cover, As the belt comes into contact with the deposits, the running resistance of the belt increases, and the deposits enter the shaft part of the guide rollers, causing poor rotation of the rollers. There is a point.
【０００５】 また、従来のパイプコンベヤには、次のような問題点がある。 (ａ) 往路が環状に丸められているパイプコンベヤでは、運搬量は、その断面 積によって決められてしまい、もしオーバーチャージされると、ベルトや案内ロ ーラに無理が生じて、これらを損傷したり、運転不能となったりする。Further, the conventional pipe conveyor has the following problems. (a) In the case of a pipe conveyor where the outward path is rolled into an annular shape, the carrying amount is determined by its cross-sectional area, and if overcharged, the belt and guide rollers will be overloaded and damaged. Or you may not be able to drive.
【０００６】 (ｂ) 従って、平ベルトと同量の被搬送物を搬送するのに、ベルトの横幅を、 平ベルトより格段に長く、例えば２倍以上としなければならず、長距離搬送の場 合、ベルトのコストが、平ベルトに比してはるかに高価となる。(B) Therefore, in order to convey the same amount of objects as the flat belt, the lateral width of the belt must be significantly longer than that of the flat belt, for example, twice or more. In this case, the cost of the belt is much higher than that of the flat belt.
【０００７】 (ｃ) 環状に丸められているパイプコンベヤの外面のゴムは、特別のカバーが 設けられていない屋外においては、直射日光に曝されるため、劣化し易い。この ことは、特に上側の往路において顕著である。(C) The rubber on the outer surface of the pipe conveyor, which is rolled into an annular shape, is exposed to direct sunlight in an outdoor environment where no special cover is provided, and is therefore prone to deterioration. This is particularly noticeable in the upper outward path.
【０００８】 (ｄ) 往復路とも環状に丸められているパイプコンベヤにおいては、その反転 走行部において、ローラによりいったん偏平とされた後、丸められるが、その回 数は、１回の走行中に２回あり、丸められる際に外面ゴムが伸ばされ、ベルトの 疲労が激しい。(D) In a pipe conveyor in which both the reciprocating path is rounded in an annular shape, the pipe is once flattened by the rollers in the reversing running portion and then rounded, but the number of times is one during running. Two times, the outer rubber is stretched when it is rolled, which causes severe belt fatigue.

以下、本考案の一実施例を、添付図面に基づいて説明する。 図１は、本考案に係るベルトコンベヤを示すもので、無端の搬送用平ベルト( １)は、後方の駆動ドラム(２)と前方の従動ドラム(３)に掛け回され、平ベルト( １)と平行をなす連結杆(４)により、所定間隔をもって互いに平行をなすように 配設された多数の四角形の支持枠(５)により、後記するようにして支持されてい る。 なお、同図中の(６)は荷送りホッパー、(７)は荷受けホッパーである。 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a belt conveyor according to the present invention, in which an endless flat conveyor belt (1) is wound around a rear driving drum (2) and a front driven drum (3) to form a flat belt (1). ), And is supported by a large number of quadrangular support frames (5) arranged in parallel with each other by a connecting rod (4) in parallel with each other as described later. In addition, (6) in the same figure is a goods sending hopper, (7) is a goods receiving hopper.
【００１２】 図２に示すように、往路ベルト(1a)は、各支持枠(５)の上面に、往路ベルト(1 a)と直角方向を向き、かつ中央部が凹入するように、開脚Ｕ字状に配設された、 ３個１組の多数組の支持ローラ(８)により、上向弧状に浅く湾曲する樋状に支持 されている。なお、支持ローラ(８)をすべて水平として、往路ベルト(1a)を偏平 状に支持することもある。As shown in FIG. 2, the outward path belt (1a) is opened on the upper surface of each support frame (5) in a direction perpendicular to the outward path belt (1a) and with the central portion recessed. It is supported in the shape of a trough that is shallowly curved in an upward arc shape by a large number of sets of support rollers (8) arranged in a U-shape. In addition, all the support rollers (8) may be horizontal and the outward belt (1a) may be supported in a flat shape.
【００１３】 各支持枠(５)内には、中央に正六角形の孔(9a)が穿設された支持板(９)が固着 されており、この六角形の孔(9a)の各辺に沿って固着された枢支金具(10)をもっ て、６個の保形ローラ(11)が、孔(9a)の内接円より若干小径の内接円をなすよう に環状に配設されている。A supporting plate (9) having a regular hexagonal hole (9a) formed in the center is fixed in each supporting frame (5), and each side of the hexagonal hole (9a) is fixed. Six shape-maintaining rollers (11) are arranged in an annular shape having a slightly smaller diameter than the inscribed circle of the hole (9a), with a pivotal metal fitting (10) fixed along it. ing.
【００１４】 復路ベルト(1b)は、各支持枠(５)における孔(9a)、及び環状に配設された各保 形ローラ(11)の間を通過することにより、搬送面を内方として円筒状に丸められ て回走する。The return pass belt (1b) passes through the holes (9a) in the support frames (5) and the shape-maintaining rollers (11) arranged in an annular shape so that the conveyance surface is inward. It is rolled into a cylindrical shape and runs.
【００１５】 以上の構成のみによっても、復路ベルト(1b)は、平板状に展開された後端部( 従動ドラム(３)側)から、漸次自然に丸まって、最初の保形ローラ(11)を通過す るまでに、両側端同士が互いに内外に重なった円筒状となるが、この後端部から 最初の保形ローラ(11)までの間に、図３に示すようなベルト丸め装置を設けたり 、又は前端部(駆動ドラム(２)側)とそれに最も近い保形ローラ(11)との間に、こ のベルト丸め装置と前後対称のベルト展開装置を設けてもよい。Even with only the above configuration, the return path belt (1b) gradually and naturally rolls from the rear end portion (the side of the driven drum (3)) deployed in a flat plate shape, and the first shape-maintaining roller (11) is formed. By the time it passes through, the both ends become cylindrical with both inside and outside, and between the rear end and the first shape-maintaining roller (11), a belt rounding device as shown in Fig. 3 is installed. Alternatively, a belt unfolding device symmetrical to the belt rolling device may be provided between the front end (on the side of the driving drum (2)) and the shape-retaining roller (11) closest to it.
【００１６】 図３は、このようなベルト丸め装置を示すもので、従動ドラム(３)に最も近い 支持枠(５)には、従動ドラム(３)より復路ベルト(1b)の進行方向に向い、正面視 概ね門形に配設した３本で１組をなす、２組の丸めローラ(12)(12)(12)と(13)(1 3)(13)が設けられている。 各組の両側において垂直をなすローラ(12)(12)と(13)(13)それぞれの相互間隔 は、往路ベルト(1a)の幅と、復路ベルト(1b)の直径との間において、次第に狭く なるように定めてある。FIG. 3 shows such a belt rounding device. The support frame (5) closest to the driven drum (3) faces the traveling direction of the return belt (1b) from the driven drum (3). There are two sets of rounding rollers (12) (12) (12) and (13) (13) (13) forming one set of three arranged in a generally gate shape in a front view. The mutual spacing between the rollers (12) (12) and (13) (13), which are vertical on both sides of each set, is gradually increased between the width of the forward belt (1a) and the diameter of the backward belt (1b). It is set to be narrow.
【００１７】 従って、搬送物を荷受けホッパー(７)に投下して、偏平となった復路ベルト(1 b)は、従動ドラム(３)を上方より周回した後、上述の丸め装置を通過する間に、 丸めローラ(12)と(13)により、上面と側面を支持されて、次第に樋状となり、つ いに、重合部を下方とした円筒状に、円滑かつ確実に丸められて、保形ローラ(1 1)内に突入する。Therefore, while the conveyed object is dropped on the load receiving hopper (7), the flattened return belt (1b) goes around the driven drum (3) from above and then passes through the above-mentioned rounding device. In addition, the rounding rollers (12) and (13) support the upper and side surfaces to gradually form a gutter-like shape, which is then smoothly and surely rolled into a cylindrical shape with the overlapped portion downwards to maintain the shape retention. Plunge into the roller (1 1).
【００１８】 また、図示は省略したが、復路ベルト(1b)がベルト展開装置を通過する際には 、復路ベルト(1b)は、進行方向に対して、上述の丸めローラ(12)(13)と逆の順序 で設けた同様の構成の展開ローラ(図示略)に案内されつつ展開されて、均一、か つ円滑に展開される。Although not shown in the drawing, when the return belt (1b) passes through the belt unfolding device, the return belt (1b) is moved in the traveling direction by the above-mentioned rounding rollers (12) (13). It is unfolded while being guided by a unfolding roller (not shown) having the same structure provided in the reverse order of the above, and is uniformly and smoothly unfolded.

【考案の効果】 本考案によると、次のような効果を奏することができる。 (ａ) 無端平ベルトの往路側を平らな状態で回走させ、かつその復路側を円筒 状に丸めて回走させるので、平ベルトコンベヤにおける復路側からの付着物の落 下をなくすことができる。According to the present invention, the following effects can be obtained. (a) Since the outward side of the endless flat belt is run in a flat state, and the return side is rounded into a cylindrical shape for running, it is possible to prevent the deposits from falling on the return side of the flat belt conveyor. it can.
【００２０】 (ｂ) 同一量の被搬送物を搬送するのに、従来のパイプコンベヤのベルトの横 幅より格段に狭い横幅のベルトを用いることができる。(B) A belt having a width much smaller than the width of the belt of the conventional pipe conveyor can be used to convey the same amount of the object to be conveyed.
【００２１】 (ｃ) 保形ローラの他に丸めローラを設けてあるため、ベルトを、次第に円滑 に丸めたり、逆に、丸めた状態から、展開したりすることができる。(C) Since the rounding roller is provided in addition to the shape-retaining roller, the belt can be gradually and smoothly rolled, or conversely, can be unrolled from the rolled state.
【００２２】 (ｄ) ベルトの復路側を、搬送面を内方として、かつ両側端同士が互いに内外 に重なる円筒状に丸めて回走させるので、ベルトの両側端を互いに突き合わせて 丸めるようにしたものに比して、搬送面に付着した被搬送物が、ベルトの両側端 部間を通って脱落するおそれが少ない。(D) The return path side of the belt is rolled in a cylindrical shape in which the conveying surface is inward and both ends overlap each other inward and outward so that the belt is rotated. Therefore, the both ends of the belt are abutted against each other to be rounded. Compared to other products, the objects to be conveyed attached to the conveying surface are less likely to fall off between the both ends of the belt.
【００２３】 (ｅ) パイプコンベヤにおいては、環状に丸められている外面のゴムは、特別 のカバーが設けられていない屋外においては、特に上側の往路においては、直射 日光に曝されるため劣化し易いが、本考案によると、このようなことはない。(E) In the pipe conveyor, the rubber on the outer surface that is rolled into an annular shape is deteriorated because it is exposed to direct sunlight in the outdoors where no special cover is provided, especially in the upper outward path. Easy, but according to the present invention, this is not the case.
【００２４】 (ｆ) 往復路とも環状に丸められているパイプコンベヤにおいては、その反転 走行部において、いったん偏平とされた後、丸められる回数が、１回の走行中に ２回あり、丸められる際に外面ゴムが伸ばされる回数が多く、ベルトの疲労が激 しいが、本考案では、いったん偏平とされた後、丸められる回数は半減する。(F) In a pipe conveyor in which both the reciprocating paths are rounded in an annular shape, the reversing running portion is once flattened and then rounded twice during one run. At this time, the outer rubber is often stretched and the belt is heavily fatigued. However, in the present invention, the number of rounds after being flattened is halved.
