Hereinafter, each part will be described in detail. In the drawings after FIG. 3, the wall surface is horizontal and the left side in the figure is upward.

As shown in an enlarged side view in FIG. 3, the moving endless track mechanism 60 has an endless belt 70 as an endless belt member wound between rollers 61 and 62 disposed before and after a frame 51. The endless belt 70 is provided with a suction mechanism 80 as suction means. The rotating shaft 64 of the front roller 61 of the left and right moving endless track mechanism is continuous, and the rotating shaft 64 is rotationally driven by a moving drive motor 66 via a chain 65, whereby the left and right endless belts 70 are synchronously driven. It has become so.

The endless belt 70 is a metal substrate such as a thin stainless steel plate which can be bent and deformed, as shown in FIG. 4 which is an enlarged sectional view taken along the line AA in FIG.

The guide projections 74 prevent the rollers 61 and 62 from skewing and falling off, and a corresponding groove is formed at the center of the rollers 61 and 62 in the width direction to fit the guide projections 74. Is what it is.

The suction chamber 73 has a rectangular shape (a rectangular shape slightly longer in the front and rear directions in the illustrated example) having a plurality of lengths in the front-rear direction arranged in the parallel orbit of the endless belt 70. In addition to being arranged in rows, the left and right rows are displaced by half a pitch from each other (ie, in a staggered state). That is, in other words, the elastic member 72 is
Three vertical stripes 72S located at both edges and the center of the outer surface of the
72C and a horizontal line 72X connecting the central vertical line 72C and the side vertical line 72S are formed, and the left and right horizontal lines 72X are arranged to be shifted by a half pitch in the vertical direction.
In addition, a suction hole 71A is formed in a portion of the metal substrate 71 corresponding to a substantially central position near the outer edge in the suction chamber 73.

The suction mechanism 80 is shown in FIG. 5 which is a plan view of the portion shown in FIGS. 3, 4 and 4 and FIG. 6 which is a view taken in the direction of arrow B (the endless belt 70 is shown in FIGS. 5 and 6). As shown in FIG. 7B, a pair of left and right guide plates 83 is provided with spacer plates 84 on the lower surface of the support plate 82 supported by the frame 51 via the bracket 81 and provided inside the parallel orbit outside the endless belt 70. A plurality of intake passages 85 are formed in the interior of the endless belt 70 in the front-rear direction at intervals equal to the front-rear arrangement intervals of the suction chambers 73 of the endless belt 70 (the arrangement intervals of the intake holes 71A). 8
5 is connected to suction means (not shown) via a connector 86.

Left and right guide plates 83 (spacer plates 84)
Are disposed along both sides of the support plate 82 and are located corresponding to the left and right suction chambers 73 of the endless belt 70, and the outer surfaces thereof (the lower surfaces in the middle in FIGS. 4 and 6) are parallel to the endless belt 70. It coincides with the inner surface of the orbit.

The guide plate 83 is a metal plate having a predetermined thickness made of aluminum or the like. The lower surface of the front and rear edge portions is chamfered upward with a shallow gradient, and the lower surface has a predetermined thickness with a predetermined hardness made of neoprene rubber or the like. Elastic sheet 83A
, And a sheet 83B of a low friction coefficient made of a fluororesin or the like is further attached to the lower surface thereof. At a position in the width direction corresponding to the intake hole 71A of the endless belt 70, a through-hole 83 as a suction hole forming an intake passage 85 is provided.
C is formed through.

The through hole 83C is provided in the suction chamber 7 of the endless belt 70.
FIG. 8 is a bottom view of the guide plate 83, which is disposed at an interval equal to the front-rear arrangement interval of No. 3 (that is, the arrangement interval of the intake holes 71A).
As shown in the figure, the long hole is long in the front-rear direction so that adjacent ones are not continuous.

The spacer plate 84 includes a guide plate 8.
A large-diameter vent hole 84A is formed at a position corresponding to the through-hole 83C, and the support plate 8 corresponding to the vent hole 84A is formed.
An intake pipe 86 is connected to each of the two portions.

The suction mechanism 80 having the above-described structure includes a guide plate 83.
A communication passage is formed by the through hole 83 </ b> C and the ventilation hole 84 </ b> A of the spacer plate 84.
Numeral 5 is connected to a suction device (not shown) via an intake pipe 86 so as to be sucked. Thereby, in a state where the intake hole 71A of the endless belt 70 matches the through hole 83C of the guide plate 83, the intake passage 85 communicates with the suction chamber 73,
The inside of the suction chamber 73 is sucked. Further, since the through hole 83C of the guide plate 83 is a long hole, the intake hole 71 of the endless belt 70 is formed.
A portion other than A is sucked, and the endless belt 70 (the back surface) is pressed against the guide plate 83 by this suction force, and adheres while elastically deforming the elastic sheet 83A.

The moving endless track mechanism 60 provided with the suction mechanism 80 has a negative pressure in the suction chamber 73 when the outer surface of the endless belt 70 contacts the flat surface while the suction mechanism 80 is operating. The elastic member 72 comes into close contact with the target surface, and becomes in a suction state. Since the guide plate 83 is provided along the parallel orbit of the endless belt 70 and has a plurality of intake passages 85 corresponding to the suction chambers 73 of the endless belt 70, the guide plate 8
The plurality of suction chambers 73 located on the parallel orbits outside the endless belt 70 corresponding to No. 3 are simultaneously in a suction state, whereby the endless belt 70 can obtain a stable suction force as a whole. That is, when the target surface has irregularities and the elastic member 72
Is deformed to form a gap so that the air-tight state cannot be maintained, only the suction of the suction chamber 73 corresponding to the unevenness is not performed, and the suction of the suction chamber 73 located before and after the suction chamber 73 is continued. Therefore, the suction is continued by the large number of suction chambers 73 in the endless belt 70 as a whole. Further, since the suction chambers 73 on the left and right sides of the endless belt 73 are formed so as to be shifted from each other by a half pitch, the possibility that the suction chambers 73 adjacent on the left and right will cause poor suction under the same conditions is reduced.

When the endless belt 70 is driven to rotate by the moving drive motor 66, the suction chamber 73 that moves along the guide plate 83 has a suction hole 71A whose through hole 83C (intake passage 85) is adjacent to the guide plate 83. , And the suction is continued. During this movement, the endless belt 70 is in close contact with the guide plate 83 by the suction force through the through-hole 83C as described above, but can move smoothly by the action of the sheet 83B having a low friction coefficient on the surface. In addition, at the front and rear ends of the guide plate 83 adjacent to the front and rear rollers 61 and 62, the suction chamber 73 which has reached a position corresponding to the intake passage 85 of the guide plate 83 by the orbital movement of the endless belt 70 starts suction. Then, the suction chamber 73 that has come off the guide plate 83 is no longer suctioned and the suction is released. Here, both sides of the guide plate 83 (the endless belt 7)
0 is round in both directions).
1A is disengaged from the guide plate 83 and the inside of the suction chamber 73 becomes the suction hole 7.
After being in communication with the outside air via 1A, the roller 6
The endless belt 70 is set so as to bend along the first and second walls 62, so that the endless belt 70 can be easily separated from the wall surface.
