Thus, the drive chain 15 is driven to rotate by the X-axis gear motor 12.

The X-axis gear motor 12 is a gear motor with a brake, and is controlled by a control device 60 by an inverter.

At one location on the circumference of the X-axis drive chain 15,
As shown in FIG. 7, which is a cross-sectional view taken along the line FF in FIG. 5, the operation roller 16 is provided rotatably downward on an axis parallel to the Z axis.

A cleaning head 30 is slidably provided on the slide shaft 11.

The cleaning head 30 includes a slide piece 31 slidably fitted on the slide shaft 11.
A, a moving plate 31B is fixed to the base plate A to form an X-axis moving base 31 as a primary moving base, and a cleaning pad is provided on a lower surface (a surface facing the exterior surface) of the moving plate 31B via a pressing cylinder 32. 33 are provided.

6 along the slide shaft 11 (X
(In the axial direction). The operation direction of the operation roller 16 is reversed by the rotation of the X-axis drive chain 15,
Therefore, the X-axis direction movement base 31 is driven to reciprocate by the rotation of the X-axis gear motor 12 in one direction (the rotation of the X-axis drive chain 15 in one direction). This gives X
The cleaning pad 33 of the axial movement base 31 reciprocates in the X-axis direction.

The slide base 20L of the Y-axis direction moving base 20 is provided with an X-axis position detecting sensor 17 as a proximity sensor so as to detect the cleaning head 30 located at the stroke end where the moving direction is reversed. The detection signal from the X-axis position detection sensor 17 is input to the control device 60.

Thus, the exterior surface maintenance device 1 configured as described above is suction-fixed to the exterior surface 2 (shown in FIGS. 2 and 3) to be cleaned of the building with the suction pad 50, and the pressing cylinder. The cleaning pad 33 is pressed against the exterior surface with a predetermined pressure by driving the polishing cloth 3.
By pressing the 3A against the exterior surface 2 and driving the X-axis gear motor 12, the cleaning head 30 (cleaning pad 33) reciprocates in the X-axis direction to clean the corresponding exterior surface. After the cleaning head 30 has reciprocated a predetermined number of times to complete the cleaning, the Y-axis gear motor 23 is driven to rotate by a predetermined amount and the Y-axis direction moving base 2 is rotated.
0 is moved in the Y-axis direction to position the cleaning pad 33 in the uncleaned area, and the same movement (cleaning) in the X-axis direction as described above is performed. By repeating such an operation, the entire area of the exterior surface 2 corresponding to the moving area of the cleaning pad 33 surrounded by the frame 40 can be cleaned.

Here, since the pressing cylinder 32 is an air cylinder, the pressing force can be appropriately adjusted according to the type of the exterior material and the degree of contamination by changing the supplied working air pressure. The rotation speed of the X-axis gear motor 12 can be arbitrarily changed by inverter control.
The moving speed of 3) can be appropriately set.

As shown in FIG. 9, the control device 60 includes an X-axis position detection sensor 17 and a Y-axis position detection sensor 26 (26).
U, 26L) and the input information from the rotary encoder 24, the X-axis gear motor 12, the Y-axis gear motor 23, and the pressing cylinder 32 are drive-controlled, and are operated or set by a manual operation via the operation panel 61. X
Number of reciprocating movements in the axial direction and amount of movement (range) in the Y-axis direction
Performs automatic operation.

That is, as an example of the automatic operation, first, the Y-axis upper sensor 26U detects the Y-axis direction moving base 20 and the X-axis position detection sensor 17
After that, the pressing pad 32 is driven to press the cleaning pad 33 against the exterior surface 2 with a predetermined pressure to bring the polishing pad 33A into the exterior surface 2.
The cleaning head 30 (cleaning pad 33) is reciprocated in the X-axis direction by driving the X-axis gear motor 12.

Here, the detection signal from the X-axis position detection sensor 17 is counted, and when the number of reciprocations reaches a set number, the X-axis position detection sensor 17 causes the cleaning head 30 to rotate.
Is detected (X-axis origin), the X-axis gear motor 12 is stopped, and the pressing cylinder 32 is driven in reverse to release the pressing of the cleaning pad 33. Then, the Y-axis gear motor 23 is rotated by a predetermined amount based on the information from the rotary encoder 24, and the Y-axis direction moving base 2 is rotated.
0 is moved in the Y-axis direction by a set amount, and the pressing cylinder 32 and the X-axis gear motor 12 are driven (the pressing of the cleaning pad 33 and the reciprocating movement of the cleaning head 30 in the X-axis direction) as described above. Until the amount of movement of the Y-axis direction movement base 20 in the Y-axis direction detected by the information from the rotary encoder 24 becomes the set amount, or the Y-axis lower sensor 26L detects the Y-axis direction movement base 20 It is a repetition.

As a result, any or all of the movement areas of the cleaning pad 33 surrounded by the frame 40 can be automatically cleaned.

According to the exterior surface maintenance apparatus 1 having the above configuration, the cleaning head 30 is driven by driving the motors (the X-axis gear motor 12 and the Y-axis gear motor 23).
Moves linearly in the X-axis direction and the cleaning pad 33
The cleaning operation can be performed and the cleaning area can be moved by moving in the Y-axis direction, and the cleaning operation becomes extremely easy. Further, since the cleaning head 30 can be installed by being rotated 90 degrees (the X-axis direction is vertical) on the exterior surface 2, cleaning is performed in accordance with the movement direction of the cleaning head 30 (the cleaning direction by the cleaning pad 33) according to the state of the exterior surface 2. Becomes possible.

Further, since the cleaning pad 33 is pressed by the pressing cylinder 32 which is an air cylinder and is swingably mounted on the cylinder rod via the spherical bearing 34, the cleaning pad 33 is applied to the exterior surface 2 with a uniform pressure. The outer surface 2 can be pressed and swung in accordance with the unevenness of the outer surface 2 to uniformly clean the outer surface 2.

Incidentally, the structures of the primary direction movement drive mechanism and the secondary movement drive mechanism are not limited to the above structure examples, but can be changed as appropriate.
