    • 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.
    • 一个气动棒输送装置,其中压缩空气从多个保持槽中的空气注入口朝向棒状材料供应,间歇地由间歇供气机构供给,从而压缩空气将被 一个齿形部分,突出地设置在所述保持槽之间比空气截止时间段更长的周期。 经过一定时间的压缩空气供应到保持槽中后,关闭压缩空气的供应,以减少保留在保持槽和输送管道中的压缩空气的出口压力,导致与 从空气喷射口供给到保持槽的压缩空气的入口压力。 因此,压缩空气以较高的速率从保持槽流入输送管道,从而对保持槽中的棒状材料施加大的初始流速。
