Description

本発明は、傾斜搬送方向に沿って被搬送物品を搬送する傾斜経路部と、この傾斜経路部の上方端側に配置されて前記被搬送物品を水平搬送方向に沿って搬送する上位水平経路部との間に、接続経路部を配置した傾斜搬送装置に関する。   The present invention provides an inclined path portion that conveys the article to be conveyed along the inclined conveyance direction, and an upper horizontal path section that is disposed on the upper end side of the inclined path portion and conveys the article to be conveyed along the horizontal conveyance direction. It is related with the inclination conveyance apparatus which has arrange | positioned the connection path | route part between.

上記傾斜経路部と上位水平経路部を備えた傾斜搬送装置の一例が、たとえば特許文献1に開示されている。この特許文献1には、水平方向に配置された下位水平フレームにローラを介してコンベヤベルトが案内される第1切り出しユニットと、この第1切り出しユニットの上方位置で水平方向に配置された上位水平フレームにローラを介してコンベヤベルトが案内される第3切り出しユニットと、これら第1切り出しユニットと第3切り出しユニットとの間に、傾斜方向に配置された傾斜フレームにローラを介してコンベヤベルトが案内される第2切り出しユニットを配置して接続した傾斜搬送装置が開示されている。   An example of an inclined conveyance device provided with the inclined path portion and the upper horizontal path portion is disclosed in Patent Document 1, for example. This Patent Document 1 discloses a first cutout unit in which a conveyor belt is guided via a roller to a lower horizontal frame arranged in a horizontal direction, and an upper horizontal arranged in a horizontal direction above the first cutout unit. A conveyor belt is guided through a roller to a third cutting unit in which the conveyor belt is guided to the frame via a roller, and between the first cutting unit and the third cutting unit, and between the first cutting unit and the third cutting unit. An inclined conveyance device in which a second cut-out unit is arranged and connected is disclosed.

上記傾斜搬送装置において、傾斜フレームを有する第2切り出しユニットと上位水平フレームを有する第3切り出しユニットとは、大きい連結角で接続されているため、その接続位置で被搬送物品が急激に傾動しガタついて不安定となり、被搬送物品の形状や重心、搬送速度などにより、被搬送物品が転倒するおそれがある。このため、被搬送物品のスムーズな乗り移りができないという問題があった。   In the inclined conveying apparatus, since the second cutting unit having the inclined frame and the third cutting unit having the upper horizontal frame are connected at a large connecting angle, the article to be conveyed is inclined sharply at the connecting position. Therefore, the article to be conveyed may fall down due to the shape, center of gravity, conveyance speed, etc. of the article to be conveyed. For this reason, there has been a problem that smooth transfer of articles to be conveyed is not possible.

この対策として、図16に示すように、第3切り出しユニットを2つに分離し、上位水平フレーム103と第2切り出しユニットの傾斜フレーム101との間に、傾斜フレーム101の1/2の傾斜角で傾斜される接続フレーム102を設け、傾斜フレーム101と接続フレーム102、および接続フレーム102と上位水平フレーム103の2つの接続部で、特許文献1の接続部に比較して連結角がそれぞれ1/2とすること、すなわち傾斜フレーム101の傾斜角を緩和して被搬送物品を乗り移らせることが考えられている。そして、この構成では、主傾斜フレーム101と接続フレーム102の接続部に下プーリ104が設けられ、さらに接続フレーム102と上位水平フレーム103の接続部に上プーリ105が設けられ、これら上下プーリ104,105と各フレーム101,102,103のローラ101a,102a,103aとにより、コンベヤベルト106が案内される。
特開平10−273219号公報
As a countermeasure against this, as shown in FIG. 16, the third cutout unit is divided into two, and between the upper horizontal frame 103 and the tilted frame 101 of the second cutout unit, the half tilt angle of the tilted frame 101. The connection frame 102 is inclined at a slope, and the connection angle of each of the two connection portions of the inclination frame 101 and the connection frame 102 and between the connection frame 102 and the upper horizontal frame 103 is 1/2, compared to the connection portion of Patent Document 1. In other words, it is considered to reduce the inclination angle of the inclined frame 101 and transfer the article to be conveyed. In this configuration, a lower pulley 104 is provided at a connection portion between the main inclined frame 101 and the connection frame 102, and an upper pulley 105 is provided at a connection portion between the connection frame 102 and the upper horizontal frame 103. The conveyor belt 106 is guided by 105 and the rollers 101a, 102a, 103a of the frames 101, 102, 103.
Japanese Patent Laid-Open No. 10-273219

図16の搬送装置は、傾斜フレーム101と接続フレーム102、および接続フレーム102と上位水平フレーム103の2つの接続部で、特許文献1の接続部に比較して連結角がそれぞれ1/2となるものの、やはり被搬送物品の搬送面(コンベヤベルト面)が多角形状となるため、下プーリ104と上プーリ105の対応部ではスムーズな移載ができず、すなわち被搬送物品の角度が順次2段階に移動して不安定になりやすく、重心が高い被搬送物品の場合には転倒する恐れもあった。また上下プーリ104,105には、被搬送物品が姿勢を変えて乗り移る際に大きな荷重がかかり、さらに被搬送物品の荷重以外にベルトの張力を支持するため、強度を有する上下プーリ104,105が必要で、部品コストが嵩むという問題があった。   In the transport device of FIG. 16, the connection angle is halved at two connection portions of the inclined frame 101 and the connection frame 102 and between the connection frame 102 and the upper horizontal frame 103 as compared with the connection portion of Patent Document 1. However, since the conveyance surface (conveyor belt surface) of the article to be conveyed has a polygonal shape, smooth transfer cannot be performed at the corresponding portion of the lower pulley 104 and the upper pulley 105, that is, the angle of the article to be conveyed is sequentially two steps. In the case of an article to be transported having a high center of gravity, there is a risk of falling. Further, the upper and lower pulleys 104 and 105 are subjected to a large load when the article to be transported changes its posture, and the upper and lower pulleys 104 and 105 having strength are used to support the belt tension in addition to the load of the article to be transported. There was a problem that it was necessary and the component cost increased.

また傾斜フレーム101と接続フレーム102、および接続フレーム102と上位水平フレーム103の2つの接続部の組立、据付時において、左右の位置が水平となるように(各フレーム101,102,103のローラ101a,102a,103aが水平になるように)調整することは難しく、調整に時間がかかるという問題があった。左右の位置が水平にならないと(ローラ101a,102a,103aが水平にならないと)、案内されるコンベヤベルトが蛇行して、被搬送物品の乗り移りがスムーズに行えないという問題がある。   Further, when assembling and installing the two connecting portions of the inclined frame 101 and the connection frame 102, and the connection frame 102 and the upper horizontal frame 103, the left and right positions are horizontal (the rollers 101a of the frames 101, 102, and 103). , 102a, 103a are difficult to adjust), and there is a problem that adjustment takes time. If the left and right positions are not horizontal (the rollers 101a, 102a, and 103a are not horizontal), there is a problem that the guided conveyor belt meanders and the transfer of articles to be conveyed cannot be performed smoothly.

本発明は上記問題点を解決して、傾斜経路部と、この傾斜経路部の上方端側の上位水平経路部との間に、接続経路部を配置して接続し、傾斜経路部の傾斜角が大きくても、被搬送物品を安定して搬送でき、部品コストを削減できる傾斜搬送装置を提供することを目的とする。 The present invention solves the above-described problems, and arranges and connects a connecting path portion between the inclined path portion and the upper horizontal path portion on the upper end side of the inclined path portion. There also greatly, can stably transport the transported goods, and an object thereof is to provide an inclined transport device can be reduced component costs.
