That is, the rotational drive shaft is rotated by driving the rotational drive unit, and the rotational transmission means is rotationally driven via the rotational direction changing mechanism, so that the roller group is driven and rotated to be conveyed by the roller group. Objects can be transported on the transport path. At that time, the endless belt does not need to be twisted, so that the endless belt has high durability, such as being hardly worn. Further, when the endless belt is cut, the endless belt can be replaced only by removing one of the annular bodies from the conveyor frame side.

At that time, the rotation of the rotation drive shaft in each linear conveyor section is transmitted to one of the ring bodies via the rotation direction changing mechanism to drive and rotate, thereby causing the flat belt extended between the pair of ring bodies to rotate. By rotating, the roller group in contact with the flat belt can be driven and rotated. That is, the rotation drive shaft group is integrally rotated by driving one rotation drive unit, and each linear conveyor unit is driven to rotate the rotation transmission means via the rotation direction changing mechanism, thereby driving and rotating the roller group. Thus, the object to be transported supported by the roller group can be transported on each linear transport path made straight.

As described above, the three linear conveyor units 1 and the one curved conveyor unit 51 are connected to each other so that each linear conveyance path 8 and the curved conveyance path 58 are continuous, and one rotational drive unit 30 performs four. A roller conveyor facility adapted to drive the two rotary transmission means 10, 60 can be configured.

  The conveyance of the object to be conveyed by the roller conveyor equipment configured as described above is performed as follows. That is, by driving the rotation drive unit 30, the drive rotation of the output shaft 31 can be transmitted to the rotation drive shaft 20 via the winding interlocking mechanism 32, and thus connected to the rotation drive shafts 20, 70. Rotate the group as a unit. The rotation of the rotary drive shaft 20 in each linear conveyor unit 1 can be transmitted to one guide wheel 11A via the drive-side miter gear 26 and the passive-side miter gear 27, thereby driving one guide wheel 11A. Rotate. As a result, the flat belt 13 extended between the pair of guide wheels 11A and 11B is rotated. At this time, the flat belt 13 pushed up and guided by the group of push-up wheels 14 comes into contact with the lower surface of the roller 6 group. As a result, these groups of rollers 6 can be driven and rotated. The rotation of the rotary drive shaft 70 in the curved conveyor 51 can be transmitted to one guide wheel 61A via the drive-side miter gear 76 and the passive-side miter gear 77, so that the one guide wheel 61A is transmitted. Rotate the drive. As a result, the V-belt 63 extended between the pair of guide wheels 61A and 61B is rotated, and at this time, the V-belt 63 guided in a curved shape by the guide wheels 64 is the conical roller 56 group. By contacting the lower surface, the conical rollers 56 can be driven and rotated.

  That is, by driving one rotation drive unit 30, the rotation drive shafts 20 and 70 are integrally rotated via the winding interlocking mechanism 32, and in each conveyor unit 1 and 51, the rotation direction changing mechanisms 25 and 75 are provided. The rotational transmission means 10 and 60 are rotationally driven through this, and the rollers 6 and 56 group are driven and rotated so that the rollers 6 and 6 extend from the continuous linear conveying path 8 to the curved conveying path 58. The to-be-conveyed object currently supported by 56 groups can be conveyed. As a result, three (single or plural) linear conveyor sections 1 and one (single or plural) curved conveyor sections 51 are connected and driven by one rotational drive section 30. Therefore, a roller conveyor facility having a long (arbitrary length) conveyance path including the curved conveyance path 58 can be realized at low cost (cost reduction).

  At that time, as the endless belt for transmission, the flat belt 13 and the V belt 63 that do not need to be twisted can be used. In this case, the flat belt 13 and the V belt 63 are not easily worn and have good durability. Therefore, high-speed conveyance (high-speed driving) can be realized stably and easily. Further, when the flat belt 13 or the V belt 63 is cut, it is only necessary to remove one guide wheel 11A, 61A provided with the passive-side miter gears 27, 77 from the conveyor frame 3, 53 side. The belt 63 can be replaced, and the maintainability can be improved. Further, as the rotation direction changing mechanisms 25 and 75 for performing the rotation transmission from the rotation drive shafts 20 and 70 to the rotation transmission means 10 and 60, the meshing structure comprising the drive side miter gears 26 and 76 and the passive side miter gears 27 and 77 is employed. By adopting a miter gear mechanism, reliable rotation transmission can be performed and the whole can be configured compactly.
