Claims

[Claims for Utility Model Registration] (1) A doffing device used in an automatic tube changer in the spinning process, which is composed of a 10-link mechanism and a gripping means mechanically connected to the 10-link mechanism. In the above ten link mechanism, the first link is a fixed frame, and the second link, the fourth link, the seventh link, and the eighth link each having one end rotatably connected to the first link. , a third link whose one end is rotatably connected to the other end of the second link, and whose other end is rotatably connected to the other end of the fourth link;
One end of it is the other end of the 4th link, and the other end is the 8th link.
A fifth link which is rotatably connected to the other end of the link and has an upper lifting lever extended at a predetermined fixed angle, one end of which is connected to the other end of the seventh link, and the other end of which is connected to the other end of the eighth link. A sixth link rotatably connected to each end, and a seventh link connected to one end of the sixth link.
A ninth link as a lower lifting lever is rotatably connected to the other end of the link, and one end of the ninth link is rotatably connected to the other end of the upper lifting lever formed as an extension of the fifth link, and the other end is rotatably connected to the other end of the upper lifting lever formed as an extension of the fifth link. and a tenth link rotatably connected to the other end of the ninth link, and the gripping means is formed integrally with the tenth link, and the second link is rotatably driven in a predetermined direction. When pulling out the 5th link, use the upper lifting lever.
The first four-section mechanism formed by the sixth link, the ninth link, and the tenth link is supported by the second four-section mechanism formed by the first link, the sixth link, the seventh link, and the eighth link. , by controlling the movement of one end of the fifth link by the third link and the fourth link, the gripping means formed integrally with the tenth link is raised in a straight line and then further raised in an arc shape, so that the bobbin is fully loaded. 1. A doffing device for an automatic tube changer in a spinning machine, characterized in that the doffing device is configured such that the doffing device is drawn up in a straight line along the axial direction of a spindle and then raised in an arc to be taken into the automatic tube changer. (2) The gripping means includes a gripping frame integrally molded with the tenth link, and a pair of left and right extraction claws elastically supported by the gripping frame so as to normally perform a closing operation;
It is integrally molded with one of the extraction claws, and the first
The automatic spinning machine according to claim 1, further comprising a release lever that opens the lifting pawl only when it comes into contact with an upper opening part and a lower opening part fixed to a predetermined position of the link. Doffing device for pipe changing machine.
