Abstract
A pneumatic bar conveying apparatus in which compressed air is supplied from an air injection port towards a bar-like material in each of a plurality of holding grooves is intermittently supplied by an intermittent air supply mechanism, so that the compressed air will be shut off by a tooth-shaped section protrudingly provided between the holding grooves for a longer period than an air shut-off period. After a specific period of compressed air supply into the holding groove, the supply of the compressed air is shut off to decrease the outlet pressure of the compressed air remaining in the holding groove and the conveying pipeline, resulting in an increased pressure difference as compared with the inlet pressure of the compressed air supplied into the holding groove from the air injection port. Consequently the compressed air flows at a higher rate from the holding groove into the conveying pipeline, thus imparting a large initial flow velocity to the bar-like material in the holding groove.
