  Each of the first and second objects to be conveyed is received in a state where each extends in the conveying direction and is aligned in a direction orthogonal to the conveying direction, and the first and second objects to be conveyed are changed during the conveying. In some cases, the first and second objects to be conveyed may be desired to be delivered in a state where each extends in a direction intersecting the conveyance direction and aligned in the conveyance direction.

  However, since the holding member 7 of the conventional apparatus rotates in the recesses aligned in the direction orthogonal to the conveyance direction, the first and second objects to be conveyed cannot be delivered in a state aligned in the conveyance direction.

  In view of this situation, the problem to be solved by the present invention is to receive and transport the first and second objects to be transported in a state in which each extends in the transport direction and is aligned in a direction orthogonal to the transport direction. Changing the orientation of the first and second objects to be conveyed, extending each in a direction intersecting the conveying direction, and delivering the first and second objects to be conveyed in the conveying direction.

A first and a second shaft rotatably supported by the moving member, spaced apart from each other in a direction and a circumferential direction; and (c) a first object to be releasably held; A first pad that rotates around the first axis away from the first axis in a direction perpendicular to the direction in which the first axis extends in conjunction with rotation of the first axis; (D) Hold the second object to be releasable and move away from the second axis in a direction orthogonal to the direction in which the second axis extends in conjunction with the rotation of the second axis. And (e) when the moving member passes through the first position of the moving path, the second pad rotating around the second axis. And the second pad are aligned in the axial direction and when the moving member passes through the second position of the moving path, the first pad and the second pad are A rotation drive mechanism for rotating the first and second shafts so as to line up in the direction.

  According to the above configuration, when the moving member passes through the first position of the moving path, the first pad and the second pad are aligned in the axial direction, so the first pad is the first conveyed object. An object can be received in a state extending in the circumferential direction, that is, the transport direction, and the second pad can receive a second object to be transported in a state extending in the circumferential direction, that is, the transport direction. Then, the rotation drive mechanism rotates the first and second shafts, and the first and second pads rotate in conjunction with the rotation of the first and second shafts, so that the moving member moves along the movement path. When passing through the second position, since the first pad and the second pad are aligned in the circumferential direction, the first transferred object held by the first pad and the second pad are held. The second object to be conveyed can be delivered in a state extending in a direction intersecting the conveyance direction and aligned in the circumferential direction, that is, the conveyance direction.

In the third step, when the moving member passes through the second position of the moving path, the holding of the first and second transferred objects is released and aligned in the circumferential direction. The first and second objects to be conveyed are delivered from the first and second pads, respectively.

  According to the above method, when the moving member passes through the first position of the moving path, the first pad and the second pad are aligned in the axial direction, so the first pad is the first conveyed object. An object can be received in a state extending in the circumferential direction, that is, the transport direction, and the second pad can receive a second object to be transported in a state extending in the circumferential direction, that is, the transport direction. Then, by rotating the first and second pads, when the moving member passes the second position of the movement path, the first pad and the second pad are aligned in the circumferential direction.

  In this case, the first transported object and the second transported object can be received in a state of being arranged in parallel to each other and delivered in a state of being disposed in a V shape.

  According to the present invention, the first and second objects to be conveyed are received in a state where each extends in the conveying direction and is aligned in a direction orthogonal to the conveying direction, and the first and second objects are conveyed during the conveying.
