Is guided by the sorting device 52B, the inner moving guide portion 32B, the upper switching device 50, the outer moving guide portion 33A, and the end guide portion 34A, and passes the article 56 to the branch conveyor 54A. At this time, the article 56 on the guide roller 28 climbs over the vertical member 2a supporting the chain 19, and transfers to the roller 55 located on the step 2c.

As described above, the guide roller 28 that has reached the ends of the end guide portions 34A, 34B is guided by the ring bodies 48A, 48B to be inverted, and is guided to the inner moving guide portions 41A, 41B and moves to the center of the width. Is done. After being distributed to the left and right by the lower switching device 51 (described later), the outer movement guide portion 42
A, 42B is moved outward by the guidance of, then the wheel body 47A, 4
After being guided by 7B and reversed, the starting end guide portion 31A moves and crosses the main transport path 21, thereby laterally pushing the article 56 and transferring the article 56 to the outer branch conveyor 87B. become. The same applies to the opposite side, and the guide roller 28 of the starting end guide portion 31B is guided by the sorting device 52B, the inner moving guide portion 32B, the upper switching device 50, the outer moving guide portion 33A, the end guide portion 34A, and the article 56 To the branch conveyor 54A. At this time, the article 56 on the guide roller 28 is a vertical member 2a supporting the chain 19.
Roller over the top of and is located at step 2c
Transfer to 55.

As described above, the guide roller 28 that has reached the ends of the end guide portions 34A, 34B is guided by the ring bodies 48A, 48B to be inverted, and is guided to the inner moving guide portions 41A, 41B and moves to the center of the width. Is done. After being distributed to the left and right by the lower switching device 51 (described later), the outer movement guide portion 42
A, 42B is moved outward by the guidance of, then the wheel body 47A, 4
After being guided and inverted by 7B, a plurality of starting end guide portions 31A may be provided, so that various operations such as internal maintenance and inspection, device installation, and wiring can be easily performed through the space between the vertical connecting members.

Further, by changing the length of the horizontal connecting member, the distance between the left and right frame members can be easily increased or decreased, so that the width of the main body frame can be easily changed. Further, it is possible to easily shift the mounting position of each of the vertical connecting members and the mounting position of the horizontal connecting member in the direction of the main transport path along each dovetail groove.
