Bobbin limiting device

Abstract

The invention provides a bobbin limiting device. According to the device, a poking piece starting device is integrated to a bobbin concentration area bottom supporting releasing assembly, an elastic poking piece is started through the poking piece starting device, a bobbin drops into a limiting device, after a bobbin is released, the bobbin concentration area bottom supporting releasing assembly restores, the poking piece starting device restores along with the bobbin concentration area bottom supporting releasing assembly, and the bobbin is pushed to move under the elasticity of the elastic poking piece until the bobbin is in contact with a bobbin shaft positioning plate to actively limit the bobbin axial direction; a bobbin grabbing manipulator is hinged through the pushing of an air cylinder until the bobbin is in contact with a radial positioning plate to achieve the radial direction positioning of the bobbin. By means of the device, error caused by the gap between a bobbin concentration area and the end face of the bobbin in an original positioning manner is eliminated.

Description

technical field [0001] The invention belongs to the field of textile machinery, and in particular relates to a bobbin tube limiting device, which can realize accurate positioning of the bobbin tube. Background technique [0002] Vortex spinning doffing trolley When the yarn bobbin at the position of the single spindle is spun to full, the single spindle stops working, the trolley unloads the bobbin, and replaces the bobbin with a new one at the same time and starts spinning to continue spinning. The spare empty paper tubes are carried in the trolley warehouse, and the manipulator picks up the empty paper tubes and sends them to the corresponding position. Through some complex actions, the empty bobbins are wound, and finally the entire spinning process is automated. What the manipulator accomplishes is repeatability. In order to make the feeding position of the bobbin accurate in the action of the fixed track, the initial position of the bobbin must be accurate. [0003] Th...

AI Technical Summary

Problems solved by technology

[0003] The current bobbin limit depends on the position of the bobbin magazine on the trolley. Because the bobbin needs to slide down smoothly in the bobbin magazine, the left and right distance inside the bobbin magazine cavity is larger than the size of the bobbin, which leads to inaccurate limit and the robot grabs When bobbin is used, the axial and radial position of the bobbin is not fixed, and it is more common that the doffing failure is caused by the inaccurate initial position of the bobbin during doffing

[0004] The main problem of the present invention is to ensure that the initial position of the bobbin is accurate, and to avoid doffing failure due to improper feeding of the bobbin.
