3.13.3 Self steering mechanism
This equipment has a self-steering mechanism to prevent the transfer belt from leaning to one side.
The composition of the self-steering mechanism is shown below.
Fig. 3-51
Operation flow
1. The transfer belt is inclined to the front or rear side.
2. The rib of the inclined belt contacts with either of the guide rollers and thus makes the gears rotate.
3. The gears rotate and thus their lead screws make the slider shift forward or backward.
4. The steering roller is inclined with the rack and pinion mechanism.
5. The inclined steering roller moves the inclined transfer belt to the original position.
6. The steering roller stops the leaning at a position in which the rib of the belt no longer contacts with
the guide roller.
Notes:
• The tolerance for the cutting angle of the self-steering mechanism is normally +/- 2 degrees.
• If the cutting angle does not fall within the acceptable range, check and correct the following:
1. Is the equipment installed on a flat surface? Is the equipment installed slantwise?
2. Is the transfer belt unit assembled correctly?
3. Is the transfer belt installed correctly?
