The shaft portion 10 of each divided transport roller 9 is rotatably supported by an L-shaped connecting bracket 13 between the main body portion 12 and the transmission pulley 11a. Specifically, the connecting bracket 13 includes a first connecting plate 13a extending in the vertical direction and a second connecting plate 13b extending in the horizontal direction from the lower end of the first connecting plate 13a. The shaft portion 10 of each divided conveyance roller 9 is rotatably supported on the upper portion of the first connection plate 13 a of the connection bracket 13.

  The rotational drive transmission roller 15 is disposed inside the one support frame 3a. The rotational drive transmission roller 15 extends in a direction perpendicular to the conveyance direction. A pin member 18 extending outward from one end face of the rotational drive transmission roller 15 is rotatably supported on one support frame 3a. The rotation drive transmission roller 15 and a divided conveyance roller transmission pulley 5b provided on the rotation drive shaft 4 are connected by a round belt 16a. As a result, the rotational drive from the divided conveying roller transmission pulley 5b is transmitted to the rotational drive transmission roller 15 via the round belt 16a.

Next, the operation of the width-shifting conveyance device 1 according to the embodiment of the present invention will be described.
The rotational drive from the rotational drive shaft 4 is transmitted from the divided transport roller transmission pulley 5b to the rotational drive transmission roller 15 via the round belt 16a. Subsequently, the rotational drive from the rotational drive transmission roller 15 is transmitted to the transmission pulley 11b of the rotational drive transmission shaft 20 via the round belt 16b, and the rotational drive transmission shaft 20 is rotationally driven. Subsequently, the rotational drive from the rotational drive transmission shaft 20 is transmitted from the respective transmission pulleys 11c to the transmission pulleys 11a of the respective divided transport rollers 9 via the respective round belts 16c, and the respective divided transport rollers 9 are rotationally driven.

Both the inclination angles θ1 of 9 are set to 30 °. Further, the inclination angle θ of each divided transport roller 9 is set so as to gradually decrease toward the other support frame 3b. For example, as shown in FIG. 3 (c), when the inclined angles θ1, θ2, θ3, and θ4 of the divided conveying rollers 9 are set, the inclined angle θ1 = 30 °, the inclined angle θ2 = 35 °, and the inclined angle θ3 = 40 °. The tilt angle θ4 may be 45 °.

Since it is configured, the structure of the device itself can be simplified, and the manufacturing cost can be reduced. However, if it is determined that the rotational driving torque of each of the divided conveying rollers 9 is insufficient, each of the divided conveying rollers 9 is provided with a small drive motor, and each of the divided conveying rollers 9 is supplied from the driving source of each of the conveying rollers 2. You may make it drive independently. Thereby, the transmission loss to the rotational drive of each division | segmentation conveyance roller 9 can be suppressed to the minimum. Note that the rotational driving torque of each conveying roller 2 and the rotational driving torque of each divided conveying roller 9 may be set differently in advance. Further, the length in the axial direction and the rotational driving torque may be different for each of the divided conveying rollers 9. As a result, it is possible to efficiently bring the transported objects to the width corresponding to the size and weight of the transported objects.
