The tray 7 is guided by the first guide hole 8 and passes through a front end position A of the fixed conveyor 1 and a position B below the fixed conveyor 1 as shown by a solid line and a two-dot chain line in FIG. As shown by 3, the vehicle turns to the position C in the turning direction a. This tray 7 was received from the fixed conveyor 1.
The transported object W is inverted and moved to the movable conveyor 5 at the backward tilt position.
It is listed.

The movable conveyor 5 and the receiving tray 7 are turned by a single turning operation device. As shown in FIG. 1 and FIG. 2, a two-stage stroke cylinder 9 is installed on the horizontal table 3 in an axial direction parallel to the conveying direction of the conveyed object W. 7 are connected by an arm 11. The connection point between the operating rod 10 and the arm 11 is guided to a second horizontal guide hole 13 provided in the guide plate 4.

A first link 14 is connected to an upper end of the arm 11, and a lower end of the first link 14 is bent to the first link 14 and a lower end of a second link 15 is connected. It is pivotally attached to the horizontal base 3. A roller 17 is provided at an upper end of the second link 15, and the roller 17 slidably contacts the lower surface of the movable conveyor 5. In FIGS. 2 and 3, reference numeral 18 denotes a stopper that regulates a lower turning end of the second link 15 fixed to the horizontal base 3.
