<P>PROBLEM TO BE SOLVED: To provide a simply structured lifting device that reduces parts count. <P>SOLUTION: A lifting device 1 is configured as follows: a pair of lifting/lowering bases 3, 4 is provided at lifting/lowering positions on right and left sides in a device frame 2 comprised of groovy pole members 21; multiple carrying rollers 11 are horizontally projected and arranged to be substantially parallel such that they are rotatably and pivoted on the lifting/lowering bases 3, 4; multiple posture holding rollers 13 are vertically arranged and inserted in the grooves of pole members 21; the carrying rollers 11 are maintained level so as to enable lifting and lowering along pole members 21; lifting/lowering chains 15, 17 bridged between the upper side and lower side of the device frame 2 are annularly connected via the pair of lifting/lowering bases 3 and 4 so as to impart rotations to the lifting/lowering chains 15, 17 from a lifting/lowering motor 5; and feeding means 7, 8 provided at the lifting/lowering positions of the lifting/lowering bases 3, 4 to impart rotations to the carrying rollers 11 by a friction resistance of a rotating belt 25. <P>COPYRIGHT: (C)2013,JPO&INPIT |
