It relates to a conveyor roller, at least one side of the conveyor roller converts the high-temperature waste heat generated from the bearing part of the conveyor roller into electrical energy by a thermoelectric power module or the mechanical rotation energy rotated by a rotating cylinder into electrical energy by a generator. By providing a self-powered unit equipped with a charging module that converts and charges the converted electric energy, a temperature meter, a rotation sensor, an indicator LED, and a wireless communication module, it can be used as power required by the conveyor roller itself without supplying external power Due to this, as well as displaying the presence or absence of an abnormality in the conveyor roller, it can be usefully used in the conveyor roller field to exchange data of the conveyor roller with the main server PC in real time.

In order to move the object by arranging several rollers in parallel with each other, the rollers are configured to be rotated. The rotational structure of the roller will be described with reference to Fig. 1 as follows.

As shown in Fig. 1, several rollers 11 are mounted on the frame so that they can rotate at predetermined intervals according to the length of the roller conveyor. At this time, the roller 11 is mounted so as to be interlocked by connecting the adjacent roller 11 and the ring belt 12 to each other.

Meanwhile, under the frame, as shown in FIG. 1, the drive shaft 20 is mounted in parallel with the frame. In addition, the drive shaft 20 and the roller 11 are connected by a ring belt 21 to transmit rotational force to transport the object.

However, a roller conveyor using an existing drive shaft and a ring belt has the following problems.

(1) Since the rotational direction of the drive shaft and the rotational direction of the rollers intersect, the ring belt connecting them also transmits rotational force in a twisted state. At this time, a large driving load is applied to the ring belt.

(2) Thus, the ring belt is easily broken and the roller conveyor cannot be used as the roller does not rotate.

(3) In addition, because the ring belt is stretched, the power of the drive shaft is not transmitted as desired to the roller, and the drive transmission power is lowered. Accordingly, it is difficult not only to transfer the object to a desired position, but also to a predetermined position, which may lead to poor work.
