Claims (6)

  1. 1. A conveying device is provided with: A conveying section having a conveying surface for conveying the article; A posture changing section provided at one side of the conveying section and configured to be capable of switching a forward and backward position between a first state in which the conveying section advances toward the other side and a second state in which the conveying section exits from the first state toward the one side, the posture changing section being configured to be capable of changing at least one of a position and a posture of the article by interference with the article being conveyed; A detection unit provided upstream of the posture changing unit in the conveying direction of the article, for detecting at least one of a position and a posture of the article along a direction intersecting the conveying direction, and A control unit configured to control the advance and retreat position of the posture changing unit between the first state and the second state, The control unit determines whether or not to interfere the article with the posture changing unit based on at least one of the position and the posture detected by the detection unit, and controls the advancing and retreating position of the posture changing unit based on a result of the determination.
  2. 2. The delivery device of claim 1, wherein, The article has a generally rectangular shape in plan view having long sides and short sides, The control unit controls the advance and retreat position of the posture changing unit so as to be the advance and retreat position of the second state when it is predicted that the short side of the article interferes with the posture changing unit when the advance and retreat position is in the first state.
  3. 3. The delivery device according to claim 1 or 2, wherein, The article has a generally rectangular shape in plan view having long sides and short sides, When the article is in a posture in which the longitudinal direction of the article detected by the detecting unit is substantially parallel to the conveying direction, the control unit controls the advancing/retreating position of the posture changing unit so as to be the advanced/retreated position in the second state.
  4. 4. The delivery device of claim 2, wherein, The conveying device is provided with an eliminating device for eliminating the articles from the conveying part, The control unit controls the removal device so as to remove the article from the conveying unit when it is predicted that the short side of the article interferes with the posture changing unit when the article is in the advanced and retracted position in the second state.
  5. 5. The delivery device of claim 1, wherein, The article has a generally rectangular shape in plan view having long sides and short sides, The posture changing section is capable of switching the advance and retreat position to a third state in which the position advances toward the other side portion of the conveying section by an advance amount different from the first state, When the control unit predicts that the short side of the article interferes with the posture changing unit when the article is in the advanced and retracted position in the first state and that the long side of the article interferes with the posture changing unit when the article is in the advanced and retracted position in the third state, the advancing and retreating position of the posture changing section is controlled so as to be the advancing and retreating position of the third state.
  6. 6. The conveying apparatus according to any one of claims 1 to 5, wherein, The posture changing unit includes: An interference member including a first face along the conveying direction and a second face along a direction orthogonal to the conveying direction, and And an actuator that switches a position of the interference member in a direction intersecting the conveyance direction.

Description

Conveying device Technical Field The present disclosure relates to a conveying device. Background Patent document 1 discloses a conveying apparatus including a conveyor having a horizontal conveying surface, a posture switching member capable of switching between a first state protruding so as to interfere with a part of a traveling direction side of a conveyed object traveling on the horizontal conveying surface and a second state separated from a conveying rail of the conveyed object, a guide member for guiding the conveyed object along the traveling direction at a position upstream of the posture switching member in the traveling direction, and a control unit for controlling switching operations of the first state and the second state of the posture switching member. Prior art literature Patent literature Japanese patent laid-open No. 2013-39993 Disclosure of Invention Technical problem to be solved by the invention In the conventional conveying apparatus described above, the posture switching member protrudes so as to be in the first state and interferes with the object (article) to be conveyed supplied from the upstream-side apparatus, thereby rotating the object so that the orientation of the object to be conveyed changes. However, the conveyance state of the object to be conveyed supplied from the upstream device may be at various angles with respect to the conveyance direction or at various positions in the direction intersecting the conveyance direction, and there is a possibility that a deviation may occur. Therefore, there is room for improvement in the control of the posture of the conveyed article. The purpose of the present disclosure is to provide a conveying device capable of more appropriately controlling the posture of a conveyed article according to the conveying state of the article. Technical scheme for solving technical problems (1) A conveying device according to one aspect of the present disclosure includes a conveying section having a conveying surface for conveying an article, a posture changing section provided on one side of the conveying section and configured to be capable of switching a forward and backward movement position between a first state in which the conveying section advances toward the other side and a second state in which the conveying section retreats from the first state toward the one side, the posture changing section being configured to be capable of changing at least one of a position and a posture of the article by interference with the article to be conveyed, a detecting section provided on an upstream side of the posture changing section in a conveying direction of the article and detecting at least one of the position and the posture of the article in a direction intersecting the conveying direction, and a control section configured to control a forward and backward movement position of the posture changing section between the first state and the second state, the control section determining whether the article interferes with the posture changing section based on at least one of the position and the posture detected by the detecting section, and controlling the forward and backward movement position of the posture changing section based on a result of the determination. In the conveying device according to one aspect of the present disclosure, at least one of the position and the posture of the article in the direction intersecting the conveying direction is detected by the detecting portion. Based on at least one of the position and the posture detected by the detection unit, the control unit determines whether or not to interfere the article with the posture changing unit, and controls the advancing and retreating position of the posture changing unit based on the determination result. As described above, since the advancing and retreating position of the posture changing section is controlled in consideration of at least one of the position and posture of the article in the direction intersecting the conveying direction as the conveying state of the article, the control section can more appropriately control the advancing and retreating position of the posture changing section in accordance with the conveying state of the article, for example, compared with a configuration in which the position and posture of the article are not considered. Therefore, according to the conveying device according to the embodiment of the present disclosure, the posture of the conveyed article can be more appropriately controlled according to the conveying state of the article. (2) In the above (1), the article may have a substantially rectangular shape having long sides and short sides in plan view, and the control unit may control the advance and retreat position of the posture changing unit so as to be the advance and retreat position of the second state when it is predicted that the short sides of the article interfere with the posture changing unit in the advance a
