PURPOSE:To prevent violent fall of an article due to sharp variation of speed and stabilize transportation by installing a plural number of stages of timing screws in the direction of the height of the article, in a feeding and discharging apparatus equipped with timing screws for intermittently feeding bottles into an inspection apparatus etc. CONSTITUTION:The bottles 1 transported on a conveyor 7 are fed into timing screws 2 and 8 which are synchronously driven in succession, and the side part of the bottle is engaged with the lead grooves of the timing screws 2 and 8, and separately held at the lead groove pitch and transferred at a prescribed speed. Since the lead grooves of the timing screws 2 and 8 are separated in the vertical direction, the bottles 1 are held at two positions in the vertical direction. Thus, bottles can be transported stably without being tumbled down, even if sharp variation of speed occurs. |
