It is transferred to E) and stopped by the roller stopper (s). When the transfer of the bat (V) to the collective roller conveyor (E) is confirmed by a limit switch (not shown), the lifting device (D) returns to its original position. It is on the collective roller conveyor (E). The butt (V) stopped by the roller stopper (s) releases the stop of the roller stopper (s) by operating the air cylinder (c) with a foot-operated air switch (not shown), The roller stopper (s) in the ball conveyor (F) is projected by the operation of the air cylinder (c), and the butt (V) sliding on the roller and the ball surface is stopped by the roller stopper (s).

The bat (V) on the ball conveyor (F) slides on the ball conveyor (F) by its own weight and is transferred onto the bat reversing device (H). Then, it will wait for the work thereafter. In this series of devices, the operation of the air cylinder, the stopper, the limit switch, etc. is, of course, carried out electrically in good timing so that the functions thereof are exhibited.

When it is not necessary to change the direction of the bat (V) by the direction changing device (A), the operation of the direction change is stopped,
The roller conveyor (B) is directly transferred to the roller conveyor (C) through the direction changing device (A), and the empty bat (V) after the work is conveyed by the belt conveyor (G).

The above is a description of a series of devices incorporating the direction changing device in which the mounting surface of the conveyed product interposed in the inclined conveying path is inclined. As long as the relationship between (a) and the rotation axis (b) is specific as described above, even if the surface of the turntable (a) is horizontal, the horizontal direction with respect to this horizontal turntable surface By feeding the conveyed product from the above with a belt conveyor or a pusher, or by hanging it from above, the combined center of gravity of the conveyed product and the turntable (a) will move the supporting point of the turning shaft (b) to the supporting point. If the rotary shaft (b) is disengaged in the direction opposite to the tilt direction, the rotary disk (a) changes direction.

(Effect of the Invention) Since the present invention is provided with the direction changing device by the weight of the conveyed object in the conveying path, it can be installed even in a limited narrow space between devices such as a manufacturing plant. Moreover, since the structure of the direction changing device is only based on the mounting position of the rotating shaft with respect to the rotating plate and its inclination angle, the operation is simple and reliable, and the weight of the conveyed object is used for changing the direction. The same applies to energy conservation measures.
