本発明は、搬送装置の技術に関する。 The present invention relates to a technology of a transport device.

従来、低位置搬送部において土砂を低位置で水平方向に搬送し、前記低位置搬送部で搬送した土砂を垂直搬送部において垂直方向に上昇するように搬送し、前記垂直搬送部で搬送した土砂を高位置搬送部において前記低位置搬送部よりも高位置で水平方向に搬送する、搬送装置の技術は公知となっている（特許文献１参照）。 Conventionally, earth and sand transported horizontally in the low position transport section at a low position, transported so that the sand transported in the low position transport section in the vertical direction in the vertical transport section, and transported in the vertical transport section The technology of a transport device that transports the image in the horizontal direction at a higher position than the low position transport unit in the high position transport unit is known (see Patent Document 1).

このような搬送装置は、第一ベルトコンベアと、第二ベルトコンベアと、を具備する。
当該搬送装置の第二ベルトコンベアは、そのベルトの搬送面の一部が第一ベルトコンベアにおけるベルトの搬送面の一部と互い向き合って第一ベルトコンベアに平行するように配置される。
当該搬送装置の第一ベルトコンベアおよび第二ベルトコンベアは、低位置搬送部と垂直搬送部との境界部分において搬送経路が水平方向から垂直方向に屈曲するようにそれぞれ構成され、垂直搬送部と高位置搬送部との境界部分において搬送経路が垂直方向から水平方向に屈曲するようにそれぞれ構成される。
また、当該搬送装置の第二ベルトコンベアは、そのベルトの両縁部より内側の部分においてベルトの搬送面から第一ベルトコンベア側に突出するようにそれぞれベルトの搬送面側に搬送方向に沿って配置される一対の蛇腹部材と、一対の蛇腹部材間を亘るとともに第一ベルトコンベア側に突出するようにそれぞれベルトの搬送面側に配置される複数個の仕切り板と、を備える。 Such a conveying apparatus comprises a first belt conveyor and a second belt conveyor.
The second belt conveyor of the conveying device is arranged such that a part of the belt conveying surface faces a part of the belt conveying surface of the first belt conveyor and is parallel to the first belt conveyor.
The first belt conveyor and the second belt conveyor of the conveyance device are respectively configured such that the conveyance path bends from the horizontal direction to the vertical direction at the boundary portion between the low position conveyance unit and the vertical conveyance unit. The conveyance path is configured to bend from the vertical direction to the horizontal direction at the boundary with the position conveyance unit.
In addition, the second belt conveyor of the conveying device is arranged along the conveying direction on the conveying surface side of the belt so as to protrude from the conveying surface of the belt to the first belt conveyor side at a portion inside the both edges of the belt. A pair of bellows members arranged, and a plurality of partition plates arranged on the belt conveying surface side so as to extend between the pair of bellows members and protrude toward the first belt conveyor side.

そして、このように構成された搬送装置では、土砂を、第二ベルトコンベアにおける前記仕切り板、前記蛇腹部材、前記ベルト、および、第一ベルトコンベアのベルトの搬送面、で形成される空間内に配置した状態で、低位置搬送部から垂直搬送部を経由して高位置搬送部に搬送する。 And in the conveying apparatus comprised in this way, earth and sand are put into the space formed by the said partition plate in the 2nd belt conveyor, the said bellows member, the said belt, and the conveyance surface of the belt of a 1st belt conveyor.

特開平６−７２５５６号公報JP-A-6-72556

しかしながら、このような搬送装置は、第二ベルトコンベアにおける一対の蛇腹部材間の幅が、第一ベルトコンベアのベルトの幅よりも狭くなるように構成される。
このため、搬送装置では、土砂を、第二ベルトコンベアにおける仕切り板、蛇腹部材、ベルト、および、第一ベルトコンベアのベルトの搬送面、で形成される空間内に配置する際に、土砂が配置される場所によっては、当該空間内に配置されずに第一ベルトコンベアのベルトの搬送面上から脱落するものがある。 However, such a conveying apparatus is configured such that the width between the pair of bellows members in the second belt conveyor is narrower than the width of the belt of the first belt conveyor.
For this reason, in the conveying device, when the earth and sand are arranged in a space formed by the partition plate, the bellows member, the belt, and the belt conveying surface of the first belt conveyor in the second belt conveyor, the earth and sand are arranged. Depending on the place to be used, there is a case where the first belt conveyor is dropped from the belt conveying surface without being arranged in the space.

また、このような搬送装置は、低位置搬送部と垂直搬送部との境界部分の搬送経路、および、垂直搬送部と高位置搬送部との境界部分の搬送経路は、それぞれ急角度で屈曲するように構成される。
このため、低位置搬送部と垂直搬送部との境界部分の搬送経路、および、垂直搬送部と高位置搬送部との境界部分では、第一ベルトコンベアのベルトと第二ベルトコンベアのベルトとの間の間隔が広くなって、第二ベルトコンベアにおける仕切り板、蛇腹部材、ベルト、および、第一ベルトコンベアのベルトで形成される空間内に配置された土砂が、第二ベルトコンベアにおける仕切り板および蛇腹部材と第一ベルトコンベアのベルトとの隙間から脱落するものがある。 Further, in such a transport apparatus, the transport path at the boundary portion between the low position transport section and the vertical transport section and the transport path at the boundary section between the vertical transport section and the high position transport section are each bent at a steep angle. Configured as follows.
For this reason, in the conveyance path of the boundary part of the low position conveyance part and the vertical conveyance part, and the boundary part of the vertical conveyance part and the high position conveyance part, the belt of the first belt conveyor and the belt of the second belt conveyor The interval between the two is increased, and the earth and sand disposed in the space formed by the partition plate, the bellows member, the belt, and the belt of the first belt conveyor in the second belt conveyor, There are some that fall out from the gap between the bellows member and the belt of the first belt conveyor.

このようにして、従来における搬送装置では、第二ベルトコンベアにおける仕切り板、蛇腹部材、ベルト、および、第一ベルトコンベアのベルトの搬送面、で形成される空間内に土砂が配置されず、また、当該空間内に配置された土砂が第二ベルトコンベアにおける仕切り板および蛇腹部材と第一ベルトコンベアのベルトとの隙間から脱落することによって、確実に、当該土砂を、低位置搬送部から垂直搬送部を経由して高位置搬送部に搬送することができない場合がある。 Thus, in the conventional transport apparatus, earth and sand are not arranged in the space formed by the partition plate, the bellows member, the belt, and the belt transport surface of the first belt conveyor in the second belt conveyor, The earth and sand arranged in the space is surely transported vertically from the low-position conveying section by dropping from the gap between the partition plate and bellows member of the second belt conveyor and the belt of the first belt conveyor. In some cases, the sheet cannot be transported to the high position transport section via the section.

本発明は以上の如き状況に鑑みてなされたものであり、より確実に、土砂を、低位置搬送部から垂直搬送部を経由して高位置搬送部に搬送することができる搬送装置を提供することを課題とする。 The present invention has been made in view of the above situation, and provides a transport device that can transport the earth and sand more reliably from the low position transport section to the high position transport section via the vertical transport section.
