The conveyor 4 first passes through the first cleaning area, and the first cleaning brush 1
The left and right wall surfaces are cleaned by the brush 13, and the bottom surface is cleaned by the brush 13. While being conveyed through the first cleaning area, the case a is regulated and guided by the first fence 55 in a predetermined direction of movement vertically and horizontally.

Case a, which has passed through the first cleaning area, is then conveyed through the area by the tow conveyor 4. At that time, case a is a case a of a portion of the third fence 9 corresponding to the upstream end of the conveyor line.
After the front surface contacts the end, it is further pushed downstream of the conveyor line by the pin 3 of the conveyor 4, thereby changing the direction of conveyance by 90 degrees with respect to the direction in the first washing area. . The 90° turn is then made in the horizontal plane.

Case a, whose direction has been changed by 90 degrees, is conveyed to the second cleaning area by the tow conveyor 4, and the bottom surface is cleaned by the brush 15, and the front and rear wall surfaces are cleaned by the second cleaning brushes 2, 2. While being conveyed through the second cleaning area, the case a is regulated and guided by the second fences 6, 6 in a predetermined vertical and horizontal direction, that is, in a forward direction rotated by 90 degrees.

Effects of the invention As described above, according to the invention, while the tow conveyor is transporting the rectangular case to be cleaned, the orientation of the case can be changed by 90 degrees using the three fences arranged in a predetermined manner, so that the direction of the case can be changed by 90 degrees on one conveyor line. Depending on the application, the case to be cleaned is passed through a first cleaning area which is a pre-cleaning process, and then turned in a required direction and passed through a second cleaning area which is a post-cleaning process. The advantage is that one of the opposing walls can be pre-brushed and the remaining opposing wall surface can be post-brushed.

In addition, since the case can be turned in a horizontal plane, unlike the case where the case is turned upside down, the direction of the case can be changed stably and calmly.
