CORE TUBE GRIPPER FOR CROSS-WOUND PACKAGE EXCHANGING SYSTEM

PROBLEM TO BE SOLVED: To provide a core tube gripper which can surely introduce variously different wound type core tubes into the package frame of the working place of a textile machine manufacturing a cross-wound package, can be manufactured at a low cost, and has durability against difficult environmental conditions, without additional recombination work.SOLUTION: The core tube gripper 31 has two three-point-fastening devices 38A, 38B for fixing and directing the core tube 14, both three-point-fastening devices are formed by a core tube holder 27, contact detection levers 39A, 39B, and corresponding fastening levers 40A, 40B, respectively, the respective contact detection levers are connected to the assigned corresponding fastening levers in a shape-connection manner. When the three-point-fastening device for fixing the core tube from a core tube storing part 13 is closed, the rotary axis 62 of the received core tube is appropriately directed correspondingly to a predetermined wound tube form. The rotary axis of the core tube coincides with the rotary axis of a core tube receiving tray of the package frame 20 of the assigned working place 2 at a core tube delivering place.
