Disclosed is a plate washing machine characterized by the above-mentioned.

According to the present invention, since the plate is automatically supplied in a vertically stacked state rather than horizontally, there is an effect of reducing the manufacturing cost by manufacturing the plate washer compactly. In addition, the plate horizontal detection unit can be operated only when the stacked plate is supplied in a horizontal state, it is possible to quickly prevent the device from being damaged by a plate that is incorrectly transferred to the inclined state.

In addition, since the entire plate washing machine is operated using only one driving motor, the feeding speed of the plate and the rotation speed of the brush can be easily adjusted, so that the use of the plate washing machine is convenient and the washing operation efficiency is improved. In addition, the pair of brushes rotate in the same direction with respect to the direction in which the plate is transported and the remaining auxiliary brushes can be cleaned to the upper and lower corners of the plate by rotating in the cross direction.
