PROBLEM TO BE SOLVED: To provide a carrier device in which a carrying travel body can travel smoothly and securely on a gradient passage part of a travel route.SOLUTION: The carrier device is constituted so that: linear screw shafts 21 and 22 which are mutually linked and joint and motor driven, are arranged in parallel on an inclined linear section 5c of a gradient passage part 5 on a travel route of a carrying travel body 2, and on a fixed region adjacent to at least the gradient passage part 5, of upper and lower both horizontal passage parts 3 connected to both ends of the gradient passage part 5; a front-and-rear pair of driven rollers 19 and 20 engaged with the screw shafts are arranged on the carrying travel body 2, such that an interval between the front-and-rear pair of driven rollers is a length not shorter than a linear distance between end parts of the screw shafts 21 to 23 positioned on both sides of circular arc parts 5A and 5B at upper and lower both ends of the gradient passage part 5; and the carrying travel body is caused to continuously travel between the upper and lower both horizontal passage parts 3 and 4 by using the screw shafts and at least one driven roller.SELECTED DRAWING: Figure 1
【課題】走行経路中の勾配経路部において、搬送用走行体を円滑確実に走行させることが出来る搬送装置を提供する。【解決手段】搬送用走行体2の走行経路中の勾配経路部5の傾斜直線部5Cと、当該勾配経路部5の両端につながる上下両水平経路部3の、少なくとも勾配経路部5に隣接する一定領域とに、互いに連動連結され且つモーター駆動される直線状のスクリューシャフト21,22が並設され、搬送用走行体2には、前記スクリューシャフトに係合する被動ローラー19,20が前後一対設けられ、この前後一対の被動ローラー間の間隔は、勾配経路部5の上下両端の円弧部5A,5Bの両側に位置する、スクリューシャフト21〜23の端部間の直線距離より短くない長さとして、搬送用走行体を、前記スクリューシャフトと少なくとも1つの被動ローラーにより、上下両水平経路部3,4間を連続走行させる構成。【選択図】図1
