Yarn winding device

Abstract

The present invention provides a yarn winding device which detaches a plurality of packages from a bobbin bracket when the damage of a pushing-out member and the bobbin bracket and package quality reduction are prevented. The yarn winding device supports one end of each of two shaft-shaped bobbin brackets (5) which respectively have a larger length in one direction on a turntable (4). Each bobbin bracket (5) is provided with a plurality of bobbins (9). A turntable (4) switches the position of a bobbin bracket between a winding position (P1) and a standby position (P2). The yarn winding device moves a pushing-out plate (21) from a base end of the bobbin bracket (5) to an open ed. The pushing-out plate (21) contacts with a left end and a right end of an end face of a bobbin (9) which is most adjacent with a package (10) at the side of the turntable (4) on the bobbin bracket (5) at a standby position (P2), and pushes out the package (10) frontward for detaching a plurality of packages (10). The pushing-out plate (21) can retreat to a position which is separate from a motion area of the bobbin bracket that moves along with the rotation of the turntable (4).

Description

technical field [0001] The present invention relates to a yarn winding machine for simultaneously winding yarn onto a plurality of bobbins mounted on one bobbin holder. Background technique [0002] Conventionally, a known yarn winding machine winds a plurality of bobbins continuously supplied from a spinning machine or the like on a plurality of bobbins installed in series in the axial direction of a shaft-shaped bobbin holder that is long in one direction. . This kind of yarn winding machine has such a structure: it has two bobbin supports with one end rotatably supported on the turntable. Switch between the lower winding position and the standby position for bobbin exchange. [0003] The yarn winding machine rotates a bobbin holder at a winding position, and winds yarn onto a plurality of bobbins mounted on the bobbin holder to form a plurality of packages. Then, the turntable is rotated to move the bobbin holder on which the plurality of packages are mounted to the st...

Problems solved by technology

In addition, there is a possibility that the ejection part or the contact position of the bobbin holder may be worn and damaged

In addition, the yarn wound on the bobbin pushed out by the push-out member tends to come into contact with the push-out member near the open end of the bobbin holder, which may result in lower package quality.
