The position correcting device 49 allows a frame position corrector 51 slidably mounted on a slide shaft 50 disposed in parallel with the roller 47 to be moved by a rodless cylinder 52 in a direction orthogonal to the traveling direction of the frame. At the time of loading, the misaligned building frame is pressed to one side to correct the position.

Reference numeral 53 denotes a control device for controlling each device, which stores a program for automatically controlling the movement of each device.

When the building frame A collected from the building site is to be cleaned by the main body 1, the lifter 10 of the building frame receiving device 2 is first driven as shown in FIG.
Is lowered to the lowermost position, and the collected building frames A are placed on the chain conveyor 3 in a state of being bound by, for example, a forklift. At this time, since the building frames A are often piled up while being alternately facing each other, the horizontal members B of the uppermost building frame A are placed so as to face the building frame extracting device 18 side. Then, the binding of the building frames A on the building frame receiving stand 4 is released so that the frames A can be taken out one by one.

When the automatic operation is started by operating the automatic operation start switch of the control device 53, the chain conveyor 3 is driven to transfer the building frame A to the building frame receiving stand 4 and stop. Next, as shown in FIG. 4, the lifter 10 is driven to raise the top plate 9 of the frame receiving cradle 4 at the frame receiving cradle 4, and the uppermost frame A on the frame receiving cradle 4 takes out the frame. When it reaches the same height position as the locking device 26 of the device 18, a suitably arranged position sensor detects the height and stops.

Then, the locking device 26 is advanced by driving the motor 25 of the frame removing device 18 and at the same time, the piston rod 33 of the cylinder 32 shown in FIG. 7 is contracted to rotate the locking claw 28 forward. As shown in FIG. 6, when the locking claw 28 reaches the horizontal member B of the uppermost frame A, the cylinder 3

When the uppermost building frame A is pulled out, the building frame receiving apparatus 2 prepares to take out the next building frame A. If the building frames A on the building frame receivers 4 are stacked alternately facing each other, the building frame receivers 4 are turned by 180 degrees, and the lateral frame B side of the frame A to be taken out next is taken out of the frame extracting device 18. To the side. When the frame A to be taken out next is not at the level of the locking device 26, the frame holder 4 is raised by the height of one frame. Since the movement of the building frame receiving table 4 changes depending on the stacked state of the building frames A, programming is performed so that an operation corresponding to the stacked state of the building frames A can be performed.
For example, when the locking device 26 is advanced to take out the building frame A, the presence or absence of the horizontal member B of the building frame A is detected by the horizontal member detection sensor 35. If B is not detected, the vehicle is turned 180 degrees. In this way, the building frame receiving apparatus 2 prepares for taking out the next building frame A.

When the frame A taken out of the frame receiving device 2 is transferred to the roller conveyor 45 of the frame take-out device 18, the piston rod 41 of the lifting cylinder 39 is extended to lower the roller conveyor 45. Then, the building frame A placed as shown in FIG. 9 is made to face the insertion opening 44 of the main body of the polisher 1, and the motor 46 is driven to rotate the rollers 47 so that the main body A is moved toward the main body 1 of the polisher. The adhering matter is removed while the building frame A is transferred to the carry-out conveyor 48 and passed through the main body 1 of the cleaning machine.
