Automatic bobbin exchange for twisting machines - with horizontal move-ment by extraction arms and grippers

摘要

In the automatic removal of full bobbins, along the length of the spindles in a yarn twisting machine a container (55) is used for the wound bobbins (59e) running along the length of the frame (54). A reciprocating support unit (40), mounted on the frame (54), carried the extraction mechanism (29, 30, 36) with grippers (36) matching the number of spindles (73). A separate bobbin transport unit (48) runs along the length of the spindles, between the reciprocating support (40) and the container (55), with extra pivoted shafts (51) for the grippers (36).
