The pump portion 14 and the suction pipe 15 which are small-diameter portions fall into the article alignment gap 13, but the cap portion 16 which is a large-diameter portion cannot fall into the article alignment gap 13, and the rotary table The outer peripheral portion of 5 is engaged. Therefore, the large diameter portion of the rod-shaped article 12 engages with the outer peripheral portion of the rotary table 5 and is suspended in the article alignment gap 13, and is conveyed as the rotary table 5 rotates.

Supplying means for supplying the rod-shaped article 12 onto the rotary table 5.
Reference numeral 17 denotes a hopper (not shown), a conveyor (not shown) for picking up the rod-shaped articles 12 randomly placed in the hopper and transporting them upward, and a rod-shaped article 12 dropped from the upper end of the conveyor. It is provided with a supply chute 18 which guides the lower part of the inclined rotary table 5 to drop and supply in a random state.

Further, as shown in FIG. 2, a discharge chute 19 for discharging the article 12 suspended in the article alignment gap 13 to the outside at a position slightly above the top of the rotary table 5 in the outer peripheral wall 11 in the rotational direction. Is provided. The discharge chute 19 is also arranged so as to be inclined, and the article delivered from the article alignment gap 13
It is possible to guide the sliding fall due to its own weight of 12.

However, the endless conveyor 21 is arranged in the frame 3 along the inner surface of the outer peripheral wall 11 over the range of 90 degrees in the rotational direction from the lowermost portion of the rotary table 5.

This endless conveyor 21, as shown in FIG. 2 and FIG.
A large number of guide rollers 23 are provided above the outer peripheral portion of the rotary table 5 along the outer peripheral portion of the rotary table 5, and each guide roller 23 serves as a guide means pivotally supported on the frame 3 by a vertical shaft 22, and the outer peripheral wall 11 is wound around the guide rollers 23.
