<p>The invention concerns an automatic bobbin-changing device (10) for a winding machine with a vertical winding axis, the device having a bobbin carrier (12) which can rotate about a vertical axis (13) and which can adopt two bobbin-holding positions staggered at an angle of about 180°. The bobbin carrier (12) has a total of four gripper arms (23, 26, 27, 28) which work together in pairs to grip a bobbin (1, 2). On each gripper arm (23, 26, 27, 28) is a bobbin-support surface (28) which, during the bobbin-changing operation, is positioned under the lower bobbin (1, 2) end-flange (16, 26). The bobbin is changed by lifting the bobbin carrier (12) by means of a lifting mechanism (52, 54, 55) in such a way that the bobbin (1) on the winding machine is lifted off its mounting, the bobbin carrier (12) subsequently being rotated through 180° and lowered again.</p> |
