Description

本考案は、コークス、石炭、砕石、鉱石、または、穀物等の粒状製品等を運搬するコンベアの上方側に覆設され、運搬物からの粉塵の飛散を防止すると共に、運搬物を風雨等から保護するコンベア用カバーに関する。 The present invention is laid on the upper side of a conveyor that conveys coke, coal, crushed stone, ore, or granular products such as grains, etc. It is related with the cover for conveyors to protect.

例えば、石灰石等を採石現場からセメント工場まで運搬する際には、ベルトコンベア等を用いて運搬されている。石灰石等は採石現場側で予めある程度の大きさに砕石されながらホッパからベルトコンベア上に供給され、離れた工場まで運搬されるが、コンベア上に供給される石灰石等の砕石には粒径の小さなものが含まれており、コンベア運搬中にこれらの微粒子がコンベアの振動や風等によって周囲に飛散するおそれがある。このような石灰石の微粒子は、作業者の健康被害や大気汚染等の公害の原因となるので、微粒子が周囲へ飛散しないようにコンベアライン全体にカバーが取り付けられている。
従来のコンベア用カバーとしては、例えば、半円筒形に形成されたガラス繊維強化プラスチック（ＦＲＰ）製やステンレスや鉄等の金属製のカバーが用いられている。
また、（特許文献１）には、コ字状又はアーチ状の本体を有するカバーフレームに、被運搬物を覆うシートカバーが取り付けられた運搬用コンベアのカバー装置が開示されている。
特開２００７−７６８０４号公報 For example, when transporting limestone or the like from a quarry site to a cement factory, it is transported using a belt conveyor or the like. Limestone is crushed to a certain size in advance at the quarry site, supplied from the hopper onto the belt conveyor and transported to a remote factory, but crushed stone such as limestone supplied on the conveyor has a small particle size. There is a risk that these particles may be scattered around the conveyor due to the vibration or wind of the conveyor during conveyance. Such limestone fine particles cause health hazards for workers and pollution such as air pollution. Therefore, a cover is attached to the entire conveyor line so that the fine particles are not scattered around.
As a conventional conveyor cover, for example, a glass fiber reinforced plastic (FRP) formed in a semi-cylindrical shape or a metal cover such as stainless steel or iron is used.
Further, (Patent Document 1) discloses a transport conveyor cover device in which a seat cover that covers a material to be transported is attached to a cover frame having a U-shaped or arch-shaped main body.
JP 2007-76804 A

しかしながら、上記従来の技術においては、以下のような課題を有していた。
（１）ＦＲＰ製や金属製のカバーには、カバー内を点検するための点検窓が必要となるが、点検窓を形成したり、点検窓に開閉自在な点検蓋を配設したりするには、加工や組立に工数を要し、生産性、量産性に欠けるという課題があった。
（２）点検窓がないカバーと、点検窓があるカバーを組合せ、点検窓の配置間隔を拡げることにより、低コスト化を図っている設備もあるが、カバー内を隅々まで確実に点検することが困難になり、点検作業性、メンテナンス性が低下するという課題があった。
（３）金属製のカバーの場合、強度を確保するためにカバー本体を波板で形成するが、点検窓を確実に覆うために、点検蓋もカバー本体と同様の波板で円弧状に形成しなければならず、加工工数、材料費が増加し、著しく量産性、低コスト性に欠けるという課題があった。
（４）また、可燃性のＦＲＰは燃焼時に有毒ガスを発生するため、火災発生時や廃棄処理時の安全性、環境保護性に欠けるという課題があった。
（５）（特許文献１）では、透明なシートカバーを用いることにより、点検窓を形成することなく、コンベア本体の運搬状態を外部から容易に確認することができるが、耐久性、固定安定性に欠けるという課題を有していた。
（６）また、径時変化で紫外線劣化し易く、視認性が低下して、外部からの確認が困難となり、耐久性、使用性に欠けるという課題を有していた。 However, the above conventional techniques have the following problems.

(2) Although there is equipment that reduces the cost by combining the cover without the inspection window and the cover with the inspection window, and increasing the arrangement interval of the inspection windows, the inside of the cover is inspected reliably. This makes it difficult to perform inspection workability and maintenance.
(3) In the case of a metal cover, the cover body is formed with a corrugated sheet to ensure strength, but the inspection lid is also formed in an arc shape with the same corrugated sheet as the cover body in order to securely cover the inspection window. However, there is a problem that the number of processing steps and material costs increase, and the mass productivity and the low cost are remarkably lacking.
(4) Further, since flammable FRP generates toxic gas at the time of combustion, there is a problem that it lacks safety and environmental protection at the time of fire or disposal.
In (5) (Patent Document 1), by using a transparent sheet cover, it is possible to easily check the transport state of the conveyor body from the outside without forming an inspection window. Had the problem of lacking.
(6) In addition, there is a problem that ultraviolet rays are easily deteriorated due to changes with time, visibility is lowered, it is difficult to confirm from the outside, and durability and usability are lacking.
