A guide surface 25 for guiding the movable table 3 is formed by the inner surface. An opening formed between the front end surfaces 15; 15 of the regulating plate 14 constitutes the upper opening 26.
The support legs 10 are provided so as to extend in the same direction from both ends in the longitudinal direction on the lower plane 27 of the bottom plate 12 of the movable platform guide 11.

  In the fixed table 2, the upper opening 26 of the movable table guide 11 is directed upward, the longitudinal direction of the movable table guide 11 is orthogonal to the traveling direction X of the conveyor belt 52, and the movable table guide 11 is connected to the conveyor belt 52. Is fixed to the floor 51 by attaching the lower end fixing portion (not shown) of the support leg 10 to the floor 51 with a mounting tool such as a bolt (not shown). .

  The movable table 3 is formed of a long frame material that is long in one direction and includes a bottom plate 30 and a side plate 32, and has a concave cross section perpendicular to the longitudinal direction. That is, the movable base 3 is provided perpendicular to the upper plane 31 of the bottom plate 30 by extending in the same direction from the long side edges of both the bottom plate 30 and the bottom plate 30, for example. And a pair of side plates 32; 32 facing each other in parallel. Movable by the outer surface of the movable table 3 having a concave cross section formed by the lower plane 33 of the bottom plate 30, the outer wall plane 34 of both side plates 32 continuous with the lower plane 33 of the bottom plate 30, and the upper end surfaces 35 of both side plates 32. A sliding surface 36 that is guided by the guide surface 25 of the table guide portion 11 is formed.

  The movable table 3 has a sliding surface 36 that can move in the longitudinal direction of the movable table guide portion 11 by sliding on the guide surface 25 of the movable table guide portion 11. It is attached so as to be fitted to the guide surface 25 of the guide part 11. Thereby, the movable platform 3 is arranged so as to face the conveying surface 53 of the conveyor belt 52 on the return side of the belt conveyor 50, and moves in a direction crossing the conveyor belt 52 perpendicular to the traveling direction X of the conveyor belt 52. Is possible. That is, the sliding mechanism 36 and the guide surface 25 form a guide mechanism 40 that guides the movable table 3 so as to be movable only in the direction crossing the conveyor belt 52.

  The size of the sliding surface 36 having a concave cross section formed by the outer surface of the movable table 3 and the size of the guide surface 25 having a substantially sectional concave shape formed by the inner surface of the movable table guide portion 11 are as follows. It is formed so as to be able to move on the guide surface 25 without rattling in the direction crossing the conveyor belt 52 perpendicular to the traveling direction X of the conveyor belt 52. That is, the guide surface 25 of the guide mechanism 40 guides the movable table 3 so that the guide surface 25 can move only in the direction across the conveyor belt 52, and restricts the movement of the movable table 3 in directions other than the direction across the conveyor belt 52. In particular, since the movable table guide portion 11 includes the restriction plate 14, the vertical movement of the movable table 3 can be suppressed. Therefore, the state of the conveyor belt 52 can be detected with high accuracy.

  The regulating plate 14 of the movable table guide unit 11 is engaged with the upper end surface 35 of the side plate 32 of the movable table 3 in a state where the movable table 3 is installed on the guide surface 25 of the movable table guide unit 11, and The length is set so as not to protrude from the inner wall plane 22 of the side plate 32. That is, as shown in FIG. 2, the regulating plate 14 of the movable table guide section 11; the front end surface 15 of the movable table 14; the distance a between 15 and the side plate 32 of the movable table 3 of the movable table 3; The distance b between 22 is formed such that distance a> distance b. Since the distance a> the distance b, the detector 4 attached to the inside of the movable table 3 receives the electromagnetic waves transmitted from the transmission unit of the conveyor belt 52, and the electromagnetic waves are regulated by the regulating plate 14 of the movable table guide unit 11. Therefore, the detector 4 can reliably receive the electromagnetic wave and the detection accuracy is improved.

  As shown in FIG. 3, the detector fixing device 60 for fixing the detector 4 to an arbitrary position of the movable table 3 is, for example, a screw formed so as to penetrate the side plate 32 in the side plate 32 of the movable table 3. The through hole 61 is formed by a screw hole 62 formed in the housing 5 of the detector 4 and a bolt 63, and the bolt 63 is inserted into the screw through hole 61 from the outer surface of the side plate 32 to the screw hole 62 of the housing 5. By being fastened, the detector 4 is attached to the movable table 3. Since the screw-through hole 61 is formed as a long hole that is long in the longitudinal direction of the side plate 32 of the movable base 3, the mounting position of the detector 4 with respect to the longitudinal direction of the side plate 32 can be freely adjusted.

  At one end in the longitudinal direction of the movable table guide unit 11, the longitudinal movement of the movable table 3 is restricted by colliding with one end in the longitudinal direction of the movable table guided by the movable table guide unit 11, and the length of the movable table 3. A reference surface 75 serving as a position reference in the direction is provided (see FIG. 1). With this reference plane 75 as a reference, the attachment position of the detector 4 and the fixed position of the movable table 3 can be easily adjusted.

  According to the best mode 1, by moving the movable table 3, the position of the detector 4 can be easily changed and the position of the detector 4 can be finely adjusted, so that the state of the conveyor belt can be detected with high accuracy. Since the detector fixing device 60 is provided, the mounting position of the detector 4 can be finely adjusted with respect to the movable table 3. Since the reference surface 75 is provided, the attachment position of the detector 4 and the fixed position of the movable base 3 can be easily adjusted. The length of the movable table 3 in the longitudinal direction is longer than the width of the conveyor belt 52 so that the movable table 3 can move in a direction crossing the conveyor belt 52 perpendicular to the traveling direction X of the conveyor belt 52. Since it is attached to the fixed base 2, a plurality of detectors 4 are attached at intervals along the longitudinal direction of the movable base 3, so that measurement such as wear measurement of the conveyor belt 52 is wide in the width direction of the conveyor belt 52. It becomes possible to carry out more precisely in the range.

  If the weight of the movable table 3 is increased so that the movable table 3 is difficult to move in the longitudinal direction due to the frictional force between the sliding surface 36 and the guide surface 25, the movable table 3 can be moved to an arbitrary position on the fixed table 2. It does not have to be fixed.

Other example 1
When the weight of the movable table 3 is increased, the movable table 3 is longer in the longitudinal direction than the movable table guide part 11, and as shown in FIG. The movable base 3 can be moved by hooking a rod 77 in the hook hole 76 in advance. Moreover, as shown in FIG. 6, you may use the movable stand 3 with the pulley 79. FIG. Moreover, you may make it move the movable stand 3 using an actuator outside a figure.

Other example 2

Other example 3
As shown in FIG. 3, a movable table fixing device 70 that prevents the movable table 3 from moving in the longitudinal direction and fixes the movable table 3 to an arbitrary position of the fixed table 2 may be provided. The movable table fixing device 70 is, for example, a screw-through hole 71 formed so as to penetrate the side plate 32 in the side plate 32 of the movable table 3, and an unillustrated shape formed so as to penetrate the side plate 13 in the side plate 13 of the fixed table 2. The movable base 3 is fixed to the fixed base by the nut being fastened to the bolt which is formed by the screw through hole, bolts and nuts not shown, and is inserted into the screw through hole from the outer surface of the side plate 13 and protrudes from the inner surface of the side plate 32. 2 is fixed. Since the screw-through hole 71 is formed by a long hole that is long in the longitudinal direction of the side plate 32, the movable base 3 can be fixed at an arbitrary position in the longitudinal direction of the fixed base 2. Can be prevented from moving in the longitudinal direction. Further, the position of the detector 4 can be finely adjusted by adjusting the fixed position of the movable table 3 with respect to the fixed table 2.
