Has been. plate
The peripheral edge of the circular arc 22a is supported by the roller 23, and is guided by a pin 24 engaged in the elongated hole 22b to rotate in a direction intersecting the transport direction. And, in the state where the rotation support means 3 does not support the work W,
The roller 20 is provided with a return means (not shown) such as a weight, a spring, an air cylinder, etc. for urging the roller 20 so that the axis of the roller 20 is positioned horizontally and the axis of the roller 21 is positioned vertically. It should be noted that, in this embodiment, the rollers 20 and 21 are provided as the supporting members having the side portions in the direction orthogonal to the supporting member 25, but the present invention is not limited to this, and is not limited to the bottom surface of the transported object. It may be anything that can contact and support the adjacent side surface. For example, a protrusion or a rail may be provided on the support member 25 as a side portion.

The work posture changing apparatus according to the present invention is not limited to the above-mentioned embodiment, and may be, for example, a chain.
15 may be hung at a certain height, and the rotation supporting means 3 may be inclined vertically toward the downstream side in the transport direction so as to be positioned relatively lower than the chain 15. It is also possible to arrange the 3 so that it gradually approaches the chain 15 in the horizontal direction.

Next, the operation of the transporting apparatus according to the present invention having the above-mentioned structure will be described. The transferred object W is placed on the roller conveyor 11 adjacent to the carry-in side of the transfer device in a state of being positioned by the guide 10, and as shown by the chain line in FIG. It is loaded so that parallel side edges are supported. When the chain 15 is driven, the roller 20 is driven to rotate and the object W to be conveyed is conveyed. Since the chain 15 is inclined in the vertical direction toward the downstream in the conveying direction so as to be gradually higher than the rotation support means 3, and is supported so as to gradually approach the rotation support means 3 in the horizontal direction, As shown in FIG. 4, the side edge of the transported object W supported by the chain 15 is located higher than the side edge supported by the roller 20. At this time, the side surface of the transferred object W is supported by the roller 21 due to the inclination of the transferred object W, and the arc 22b rotates the roller 23 while the elongated hole 22b is engaged with and guided by the pin 24 and the plate.
22 rotates, that is, the rotation support means 3 rotates in a direction intersecting the transport direction. When the chain 15 is further driven, as shown in FIG. 5, on the carry-out side of the posture changing device, the transported object W rotates the plate 22 until the pin 24 abuts on the end of the elongated hole 22b, and the roller 22 rolls. It is supported by 21, separated from the chain 15 and released from the drive, and its posture is changed by 90 ° with respect to the transport direction. After carrying out the transported object W whose posture has been changed, the rotation supporting means
3 is returned to the state of FIG. 3 by the returning means. When the posture of the transferred object W is changed by 180 °, two transfer devices according to the present invention are prepared, and the chain 15 is higher than the rotation supporting means 3 in the longitudinal direction and the chain 15 is in the horizontal direction. The ends supported by the rotation support means 3 may be arranged so as to be continuous with each other.
