Abstract
A conveyor apparatus 20 according to the present invention comprises a tread guide rail 4 which is provided on a structure 120, and a plurality to treads 2 which moves along the tread guide rail 4. The plurality of treads 2 are connected by a chain 5 having pin rollers 5a. An eccentrically rotatable eccentric crank shaft 8 is connected to a rotation drive unit 6. The eccentric crank shaft 8 is connected to an oscillating body 10 which oscillates in accordance with the eccentric rotation of the eccentric crank shaft 8. The oscillating body 10 is provided with pin roller rolling teeth 11 having a trochoid tooth profile for giving thrust to the pin rollers 5a in accordance with the oscillation of the oscillating body 10.

A conveyor apparatus comprising:
- a tread guide rail which is provided on a structure;
- a plurality of treads which move along said tread guide rail;
- a chain for connecting said plurality of treads in the form of an endless loop;
- a rotation drive unit which is mounted on said structure;
- and
- driving means for converting a rotational motion, which is transmitted from said rotation drive unit via an eccentric shaft, into an oscillating motion of an oscillating body to give thrust to said chain from said oscillating body via a pin roller, which is provided on one of said oscillating body and said chain, and a trochoid tooth profile which engages said pin roller.
