Since the spout 16 is formed, the used sponge block C fitted in the fitting hole G of the foamed synthetic resin board F is dislodged from the fitting hole G by the water spouted from the spout 16, and is pushed downward. to fall.

A water receiving case 28 is provided below the cleaning and sponge removal device 5, and a discharge outlet 29 for discharging the water in the water receiving case 28 is provided at the bottom of the water receiving case 28. A discharge box 41 is provided at the discharge outlet 29, and a recovery sponge receiving net 30 is attached removably inside the discharge box 41. Therefore, the used sponge block C that falls together with the water sprayed from the spray nozzle 15 enters the recovery sponge receiving net 30 in the discharge box 41 from the discharge outlet 29 and is collected, and the water is drained to a designated place by a hose connected to the discharge box 41.

Inside the cleaning and sponge take-out device 5, there is a first cleaning section 17 consisting of a pair of upper and lower first upper brushes 18 and a first lower brush 19, and a first cleaning section 17 consisting of a pair of upper and lower second upper brushes 21 and a second lower brush 22. Two cleaning sections 20 are provided, and upper and lower cleaning nozzles 25 and 26 are provided between the first and second cleaning sections 17 and 20, so that the water spouted from the upper and lower cleaning nozzles 25 and 26 is Rotating first cleaning section 17 and second cleaning section 20
The upper and lower surfaces of the foamed synthetic resin plate F are cleaned by the respective brushes 18, 19, 21, and 22.

In this case, the tip of the first upper brush 18 and the tip of the first lower brush 19 of the first cleaning section 17, and
The tips of the second upper brush 21 and the tips of the second lower brush 22 of the second cleaning section 20 are arranged so that they partially overlap in side view (FIG. 10), and the foamed synthetic resin plate F is fitted. The inside of hole G can also be cleaned.

Further, the upper and lower brushes 18 of the first cleaning section 17,
The upper and lower brushes 18 and 19 of the first cleaning section 17 are configured to rotate in the directions of arrows A and B, which are the conveying directions of the foamed synthetic resin board F, on the contact surface of the foamed synthetic resin board F. slides against the inner wall 23 on the terminal end side of the fitting hole G.

The upper and lower brushes 21 and 22 of the second cleaning section 20 are configured to rotate in the directions of arrows C and D, which are opposite directions to the conveying direction of the foamed synthetic resin board F, on the contact surface of the foamed synthetic resin board F. , the inner wall 24 on the starting end side of the fitting hole G is rubbed and cleaned (FIG. 10).
Therefore, both sides of the terminal end side inner wall 23 and the start end side inner wall 24 of the fitting hole G can be cleaned.

Therefore, each brush 21, 2 of the second cleaning section 20
Even if the foamed synthetic resin board F has been cleaned by step 2,
Although the brushes 21 and 22 are dirty due to splashes, etc., and are not completely cleaned, in the present invention,
