ABSTRACT:
A gripper assembly having a plurality of tube gripping apparatus is provided for transferring full and empty bobbins between the bobbin bank of a textile fly frame and a supply creel. The gripper assembly is mounted on a traveling service unit and includes a drive device for commonly driving the tube gripping apparatus to synchronously grip and release tubes to be transferred. Each tube gripping apparatus includes an axially movable tube engaging member having gripping portions for compressively gripping a tube, a gripping portion drive member pivotally supported in a housing, and a pivot movement converting device for converting pivoting of the gripping portion drive member into axial movement of the tube engaging member. The gripping portion drive member is operatively connected to a common drive shaft of the gripper assembly for driving pivoting thereof. The pivot movement converting device includes a pair of diametrically opposed rollers rotatably supported on the gripping portion drive member and a cooperating cam surface formed on one end of the tube engaging member. A plurality of springs bias the rollers and the cam surface into continuous engagement with one another. Each tube gripping apparatus additionally includes a tube top engaging component and a tube insertion component for insertion into the tube to stabilize the tube during a tube transfer operation.
