A free-side connector piece 62 is provided at the tip of the motor built-in roller forward cable 68.

Next, the operation of this embodiment will be described by explaining the procedure for attaching the above-mentioned motor built-in roller 3 to the frame 2.
In the conveyor device 1 of the present embodiment, the motor built-in roller 3 is attached to the frame 2 via the attachment device 40.
In this embodiment, the fixed shaft 20 of the motor built-in roller 3 is temporarily fixed to the frame 2 prior to the main mounting of the motor built-in roller 3 as shown in FIG.

As described above, the frame pieces 7 employed in the present embodiment are provided with a large number of holes 8 in a line at equal intervals in advance.
In the present embodiment, three of these holes 8 are made into one hole group, and the attachment device 40 and the motor built-in roller 3 are attached using this hole group.
That is, the fixed shaft 20 of the motor built-in roller 3 is inserted into the central hole among the three holes 8.
Subsequently, the fixture 40 is temporarily fixed to the outside of the frame piece 7 using the holes at both ends of the three holes 8 described above. Since the frame piece 7 is a lightweight grooved steel and has a cross-sectional shape of “U”, the attachment device 40 is temporarily fixed in a region surrounded by this “U” shape.
Specifically, the flat surface portion on the back surface side of the base member 38 of the attachment device 40 is pressed against the outer side surface 9 of the frame piece 7. Here, when temporarily fixing the attachment device 40, the nut 56 engaged with the fastening member 55 is loosened.

Then, the fixed shaft 20 of the roller with built-in motor 3 is inserted into the hole 48 of the inner core body 45 of the rotation preventing member 41 attached to the base member 38, and the base member 38 is a plane on the back surface side of the base member 38 of the mounting device 40. The part is brought close to the outer side surface 9 of the frame piece 7 and finally pressed.
As described above, when temporarily fixing, the screw (nut 56) of the fastening member 55 is loosened. Therefore, the force with which the outer shell member 46 tightens the inner core body 45 is weak. It has a degree of freedom with respect to the member 46 and can change its posture.
In particular, the inner core body 45 and the outer shell member 46 are both tetrahedrons, and two hexagonal vertical walls (the front side surface 14a and the back side surface 14b) and the respective hexagonal vertical walls are defined based on the posture of FIG. It has six inclined walls (surface 14c) sharing one side with one side.
Therefore, the inner core body 45 can be easily rotated in the direction along the inclined wall (surface 14c).

Therefore, when the attachment device 40 is brought close to the outer side surface 9 of the frame piece 7, the posture of the inner core body 45 is changed in a three-dimensional rotation direction like an eyeball with respect to the eyelid (outer shell member 46), and stress is applied to the motor built-in roller 3. Do not apply.
20 and 21 are explanatory views showing the degree of freedom of the rotation preventing member 41 of the attachment device 40. FIG.
Since the inner core body 45 of the rotation preventing member 41 can be rotated three-dimensionally in the outer shell member 46 and can be changed in posture in the three-dimensional rotation direction, even if the axial center of the hole 8 of the frame 2 is slightly displaced, the motor The built-in roller 3 is hardly stressed.

  Subsequently, the head portions 55a of the fastening members 55 are inserted into the holes at both ends of the three holes 8. As described above, the length L of the head portion 55a of the fastening member 55 is longer than the depth M on the concave portion side of the unevenness changing portion 60, and the distal end side of the head portion 55a of the fastening member 55 is located on the base member 38. Therefore, the tip of the head portion 55a passes through the hole 8 of the frame piece 7 and protrudes to the inside of the frame piece 7.

Further, on the inner side of the frame piece 7, a comb-like member 49 is attached to the two fastening members 55 as shown in FIG. More specifically, the notches 49 a and 49 c on both sides of the comb-like member 49 are mounted between the slits 55 b and 55 c provided on the head portion 55 a of the fastening element 55. As described above, since the width Wa of the notches 49a and 49c of the comb-like member 49 is equal to the interval Wb between the slits 55b and 55c provided in the head portion 55a of the fastening element 55, the notches 49a and 49c are fastened. It fits into slits 55b and 55c provided in the head 55a of the element 55. Accordingly, the fastening element 55 is integrated with the comb-like member 49 in the rotational direction.
Further, in this embodiment, since one comb-like member 49 is mounted on two fastening elements 55 provided at a distance, the comb-like member 49 cannot rotate, and as a result, the two fastening elements 55 is prevented from rotating by the comb-like member 49.

Thereafter, the nut 56 that engages the fastening element 55 is tightened. As a result, the two outer shell pieces 51 and 52 are fastened together, the inner core body 45 is fastened by the outer shell member 46, and the inner core body 45 cannot be changed in posture and is fixed.
When the fixing operation of the motor built-in roller 3 to the frame 2 is completed, the inside and outside of the roller body 11 of the motor built-in roller 3 are electrically connected. In this embodiment, as shown in FIG. 19, a free side connector piece 62 is provided at the tip of a motor built-in roller forward cable 68 provided in the controller 73, and the free side connector piece 62 is fixed to the built-in motor roller 3. The conveyor device 1 is completed by being mounted on the fixed connector piece 75 in the shaft 20.

  In the embodiment described above, the inner core body 45 is configured by the two inner core body pieces 47, but may be configured by a single member. In the embodiment described above, the inner core body 45 is a tetrahedron, but may be another polyhedron. Further, the inner core body 45 may be a sphere or an ellipsoid. However, it is desirable that the inner core body 4 is polygonal rather than spherical in that the tightening force when the outer shell member 46 is tightened is strong.

  In the conveyor apparatus 1 of the present embodiment, each roller is provided in a direction perpendicular to the frame piece 7, but the attachment device 30 of the present embodiment also has a high degree of freedom in the swinging direction. It is also possible to intentionally attach each roller to the frame piece 7 like a conveyor 80 shown in FIG.

  Further, it is also recommended to use the attachment device 30 of the present embodiment at the curved portion of the conveyor device 81 as shown in FIGS. In the conveyor device 81 shown in FIGS. 23 and 24, a tapered motor built-in roller 82 is employed in the curved portion. The tapered motor built-in roller 82 is obtained by mounting a tapered sleeve (not shown) on the outer periphery of the motor built-in roller 3 (FIG. 3). In the conveyor device 81, as shown in FIG. 24, a tapered motor built-in roller 82 is attached to the frame pieces 6 and 7 so that the upper surface portion is horizontal. Therefore, in the conveyor device 81, the mounting heights of the fixed shafts 20 and 21 of the motor built-in roller 82 are different.

  In the present embodiment, the three consecutive holes 8 of the frame piece 7 are used as one hole group, and the rotation prevention member 41 is attached facing the three consecutive holes 8. The above holes may be a hole group. However, it is desirable that the number of holes 8 constituting the hole group is an odd number, and it is recommended that the fastening member 55 be attached to the holes at both ends.
