Claims (3)

  1. 1 . 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, and the first conveyance part includes an obstructing member that obstructs the conveyance of the second conveyance part.
  2. 2 . The right angle transfer device according to claim 1 , wherein 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 on the second conveyance surface.
  3. 3 . The right angle transfer device according to claim 1 , wherein the movement mechanism includes a first link mechanism connected to the first conveyance part, a second link mechanism connected to the second conveyance part, a cam mechanism that is engaged with each of the first and second link mechanisms and moves on 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 via the first and second link mechanisms, and a drive part that drives the cam mechanism.

Description

TECHNICAL FIELD The present invention relates to a right angle transfer device used in a conveyor device and capable of conveying a conveyance object in orthogonal two directions. BACKGROUND ART Conveyor devices are frequently used for moving (conveying) conveyance objects, for example, in production sites, distribution sites, and the like. The conveyor devices are roughly classified into a roller conveyor device and a belt conveyor device. The roller conveyor device is a device that includes a plurality of rollers arranged side by side along one direction, and conveys a conveyance object on the plurality of rollers as a conveyance path. The belt conveyor device includes a plurality of rollers arranged side by side along one direction, and a conveyance belt stretched around the plurality of rollers, and conveys a conveyance object on the conveyance belt as a conveyance path. Such a conveyor device is often configured to include a first conveyor part extending in one direction and a second conveyor part extending in another direction different from the one direction in order to convey conveyance objects to various conveyance destinations. The number of the second conveyor parts may be one or more with respect to the first conveyor part. In this case, in order to transfer a conveyance object between the first and second conveyor parts, a transfer device capable of conveying the conveyance object in two directions of the one direction and the other direction is arranged at a location where the one direction and the other direction intersect. Such a transfer device is disclosed in, for example, Patent Literature 1 and Patent Literature 2. The transfer device disclosed in Patent Literature 1 includes a main conveyance part, a sub conveyance part, and a lift means that lifts at least one of the main conveyance part and the sub conveyance part. The lift means includes a motor. The main conveyance part is provided with a plurality of main conveyance bodies that rotate or travel in contact with a conveyed object and send out the conveyed object in a certain direction. The sub conveyance part is provided with a plurality of sub conveyance bodies that rotate or travel in contact with the conveyed object and send out the conveyed object in a direction intersecting with respect to a conveyance direction of the main conveyance part. The main conveyance part and the sub conveyance part are arranged in an identical plane region. The transfer device conveys the conveyed object in a desired direction by the lift means raising one conveyance part higher than the other conveyance part. In the transfer device, a planar arrangement position of the motor is a planar region overlapping with the main conveyance part and the sub conveyance part. An arrangement position in a height direction of the motor is a position where a part or the entirety of the motor is higher than a height of a lower end of a rotation trajectory or a travel trajectory of any conveyance body in a state where any conveyance part descends. A conveyance body of one conveyance part is a rotation body including a roller or a small rotation body group arranged coaxially. A conveyance body of the other conveyance part is a narrow conveyor having a narrow width. The rotation bodies are arranged in parallel at regular intervals. The narrow conveyor is present between rotation bodies and appears from between the rotation bodies. An arrangement position in the height direction of a part or the entirety of the motor is higher than a height of a lowermost end of the rotation body. The transfer device disclosed in Patent Literature 2 is a transfer device including a main conveyor part that forms a part of a conveyor device and is capable of placing a conveyed object on a conveyance surface and conveying the conveyed object in a direction along a main conveyance path of the conveyor device, a sub conveyor part that is arranged in a region identical to the main conveyor part and is capable of placing the conveyed object on the conveyance surface and conveying the conveyed object in a direction intersecting a conveyance direction of the main conveyor part, and a lift means that lifts both the main conveyor part and the sub conveyor part. In the transfer device, when the conveyed object to be conveyed along the main conveyance path of the conveyor device approaches the transfer device, the conveyance surface of the main conveyor part is brought into a state of being moved higher than the conveyance surface of the sub conveyor part. When the conveyed object to be discharged from the main conveyance path of the conveyor device approaches the transfer device or reaches on the transfer device, the conveyance surface of the sub conveyor part is brought into a state of being moved to a height equal to or higher than the height of the conveyance surface of the main conveyor part. The sub conveyor part is caused to perform a conveyance operation while the conveyed object to be discha
