Abstract

The invention discloses a bobbin chuck device capable of facilitating extracting a bobbin with a chuck piece certainly separated from the bobbin in releasing and extracting the bobbin from a bobbin holder, and capable of attaining wall thinning and high-speed handling of the bobbin holder. A chuck piece 3 includes a first member 5 for the bobbin 52 and second members (4, 6) for a rotating cylinder 51. The first member 5 and the second members (4, 6) relatively approach or are separated from each other in the axial direction of the rotating cylinder 51, so that the first member 5 and the second members (4, 6) are respectively energized toward or released from the bobbin 52 and the rotating cylinder 51. When the first member 5 and the second members (4, 6) are relatively moved so that both of the members may be respectively energization-released, both of the members are kept in mutual engagement, and an engagement part for separating the first member 5 from the bobbin 52 is provided on the first member 5 and the second members (4, 6) respectively.

Description

technical field

[0001] The present invention relates to a bobbin chuck for use on the bobbin frame of a sliver winder for winding a sliver spun from a spinning machine, for inserting the bobbin on the bobbin frame . Background technique

[0002] In the bobbin holder of such a sliver winding machine, a bobbin clamp for detachably holding a cylindrical bobbin for winding the sliver is provided on the outer periphery of the bobbin holder body composed of a rotating cylinder. device. In addition, as such a bobbin clamping device, in order to obtain a strong holding force that does not allow the bobbin to slide in the circumferential direction even under high-speed rotation, mechanical clamping devices are widely used. Japanese Patent Specification Laid-Open No. 6-67461 discloses a system that includes a spacer ring inserted on the outer periphery of a rotating cylinder as the bobbin holder body and that holds / releases the bobbin as the spacer ring moves back and forth in the a...
