BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn end treatment device mounted on a yarn switching winder, and more particularly, to a yarn bobbin winding amount of a bobbin reaching a predetermined amount and other empty bobbin winding the yarn. The present invention relates to a yarn end processing device mounted on a yarn switching winder that processes a yarn end of a full bobbin so as not to be caught when switching winding.

[0002]

2. Description of the Related Art A conventional yarn end processing device mounted on a yarn switching winder is described in, for example, Japanese Utility Model Laid-Open Publication No. 59-57452.
A conventional example) inserts a shielding plate between a full bobbin and an empty bobbin when the yarn is switched.

Further, Japanese Utility Model Laid-Open Publication No. Sho 60-126467 describes a yarn end processing device (hereinafter referred to as a second conventional example) in which the shielding plate is constituted by a wire mesh.

[0004]

However, in the first conventional example, the air around the fully-loaded bobbin after the switching goes around the shielding plate due to the accompanying flow generated by the rotation of the bobbin during winding. There is a problem that the yarn wound on the full bobbin is sucked up by the air and gets caught in the bobbin holder or the like being wound over the shielding plate.

Further, in the second conventional example, the air around the full bobbin after the switching passes through the opening of the wire net due to the accompanying flow, so that the yarn wound around the full bobbin by the air forms the yarn. There is a problem in that the yarn end of the yarn is pulled out from the opening of the wire mesh and pulled out, and is caught in the bobbin holder or the like during winding. In particular, when air for air conditioning is blown from below or around the switching winder, the air pressure in the vicinity of the winder becomes high, and the winding of the yarn becomes remarkable.

Therefore, the present invention allows the shielding plate inserted between the bobbin holders to be ventilated and changes the traveling direction of the accompanying flow generated by the rotation of the bobbin during winding, thereby allowing the accompanying flow to pass through the shielding plate. An object of the present invention is to spray a full bobbin to prevent winding of a wound yarn.

[0007]

In order to achieve the above object, the present invention provides a yarn end mounted on a yarn switching winder having at least two or more bobbin holders capable of attaching and detaching a yarn winding bobbin. In the processing apparatus, when the switching winder reaches a predetermined amount of the bobbin mounted on the bobbin holder located at the yarn winding position, the other bobbin holder is moved to the yarn winding position. When moving to switch the winding of the yarn to the empty bobbin mounted on the bobbin holder, a shielding plate is inserted between the bobbin holder detached from the yarn winding position and the bobbin holder located at the yarn winding position. In the yarn end processing device mounted on the yarn change-over winder to be provided, a part or the whole of the shielding plate is provided with a plurality of ventilation holes opened in a predetermined area, and in the vicinity of the shielding plate or the shielding plate, In the axial direction of the bobbin A weir plate extending in length and changing the traveling direction of the wake generated by the rotation of the bobbin during winding is provided, and the wake is blown toward the ventilation hole provided in the shielding plate by the weir plate. It is characterized by doing so.

[0008]

According to the present invention, the bobbin holder detached from the yarn winding position when the yarn is switched and the shield plate inserted between the bobbin holder located at the yarn winding position are partially or entirely opened with a predetermined area. Advancing direction of the wake generated by the rotation of the bobbin during winding, extending a predetermined length in the axial direction of the bobbin mounted on the bobbin holder near the shielding plate or the shielding plate. A weir plate is provided to change the number. Therefore, the traveling direction of the accompanying flow generated during winding is changed by the weir plate to the shielding plate, and is blown into the ventilation hole provided in the shielding plate, and the accompanying flow passes through the shielding plate and is blown to the full bobbin. Can be Therefore, the yarn end of the yarn wound on the full bobbin is pressed against the outer periphery of the full bobbin.
