Right angle transfer device

A right angle transfer device arranged at a location where one direction and another direction intersect in a conveyor device including a first conveyor part extending in the one direction and a second conveyor part extending in the other direction orthogonal to the one direction, and capable of conveying a conveyance object in two directions of the one direction and the other direction in order to transfer the conveyance object between the first and second conveyor parts, the right angle transfer device comprising:

• a first conveyance part that forms a first conveyance surface and conveys, in the one direction, the conveyance object placed on the first conveyance surface;
• a second conveyance part that forms a second conveyance surface different from the first conveyance surface and conveys, in the other direction, the conveyance object placed on the second conveyance surface;
• and
• a movement mechanism that moves the first and second conveyance parts so as to move the first conveyance surface and the second conveyance surface in opposite directions to each other along a normal direction of the first conveyance surface,
• wherein each of the first and second conveyance parts stops the conveyance from start to end of the movement by the movement mechanism,
• the first conveyance part includes an obstructing member that obstructs the conveyance of the second conveyance part,
• the second conveyance part includes
• a frame, and
• a plurality of roller tubes arranged side by side in the frame along the other direction and rotatably pivotally supported by the frame,
• at least one roller tube of the plurality of roller tubes includes a motor that is arranged inside the roller tube and generates a drive force for rotating the roller tube,
• the first conveyance part includes a plurality of first sub conveyance parts arranged between the plurality of roller tubes,
• each of the first sub conveyance parts includes a plurality of pulleys arranged side by side along the one direction, a conveyance belt stretched over the plurality of pulleys, a support member supporting the plurality of pulleys, and the obstructing member,
• the first conveyance part further includes a drive part that drives each conveyance belt in the plurality of first sub conveyance parts, and
• the obstructing member is arranged on the support member so as to obstruct rotation of each of the plurality of roller tubes in the second conveyance part when the conveyance object is allowed to be conveyed on the first conveyance surface and the conveyance object is not allowed to be conveyed on the second conveyance surface.
