PURPOSE:To insert the pipe simply and continuously by a method wherein a groove is provided on a revolver, a pair of pipes having different diameters are set into the groove and an impact center as well as the groove are moved along a cam by revolving the revolver. CONSTITUTION:The pipe 1, having smaller diameter, is set into the groove 15 on the revolver 11 while the pipe 2, having larger diameter, is set into the groove 19a. When a shaft 12 is rotated into the direction A, the knocking center 18 as well as a large diametral pipe receiver 19 are moved by the movements of cam guides 20, 21 along cam grooves 22a, 24a and, thus, the insertion of the pipes is effected. At this time, the pipes are prevented from dropping out of the grooves by pusher plates 26, 27. When the revolver 11 is half rotated, the insertion of the pipes is finished and the pipes drop after being released from the pusher plates 26, 27, thereafter, the impact center and the pipe receiver are returned to the initial positions thereof as the revolver 11 is rotated further. |
