Device for holding and releasing the terminal in wire-like object take-up apparatus

Claim 1

In a take-up apparatus of a wire-like object, wherein a blank bobbin is rotatably supported and rotated to take up the wirelike object, and the bobbin after being fully wound with the wire-like object is replaced with another blank bobbin to continue the take-up operation, a device for holding and releasing the terminal of the wire-like object, characterized in that the device comprises: a rotary disc for supporting the bobbin on the side thereof and being rotatable therewtih; a bobbin-pushing shaft mounted to be rotatable about the same axis of rotation as said rotary disc and to be movable toward and away from said rotary disc; a projecting member movably disposed on said rotary disc adjacent the bobbin for movement along a line parallel to said axis of rotation of said rotary disc; first elastic means for urging said projecting member to move in the direction of said bobbin; a contact member movably disposed on said projecting member adjacent the bobbin for movement along a line parallel to the line of movement of said projecting member; second elastic means for urging said contact member to move in the direction of said bobbin; and a pawl connected to said projecting member to hold the wire-like object between said pawl and said rotary disc and to release the wire-like object, respectively corresponding to the movement of said projecting member in the direction away from and in the direction toward said bobbin, whereby when the bobbin is mounted between said bobbin-pushing shaft and said rotary disc and said bobbin-pushing shaft is advanced toward said rotary disc for rotatably supporting the bobbin therebetween, the bobbin pushes said contact member and said projecting member in the direction away therefrom to thereby actuate the pawl to hold the wire-like object, and when the bobbin is removed from said rotary disc, said pawl releases the wire-like object.
