Automatic shuttle changing device and method

Abstract

The invention provides an automatic shuttle changing device which comprises a rotating shuttle, wherein a first shuttle shell and a first shuttle core are arranged on a rotating shuttle spindle of the rotating shuttle in a sleeving manner. The device also comprises a fixed base plate with a bottom line allowance detection station, a grabbing station and a replacement station, a movable shuttle shell claw, a bottom line allowance detection sensor mounted on the shuttle shell claw, and a movable storage device, wherein an empty station and a storage station are formed in the storage device; a hollow rotating shaft is arranged at the empty station; a second shuttle shell and a second shuttle core are arranged at the storage station; bottom lines are fully wound on a winding post of the second shuttle core; the shuttle shell claw is used for grabbing and moving the first shuttle shell and the first shuttle core or the second shuttle shell and the second shuttle core. According to the automatic shuttle changing device disclosed by the invention, the bottom line allowance on the winding post of the first shuttle core can be detected and monitored in real time; and when the bottom lines on the first shuttle core run short, the sewing machine automatically stops, the first shuttle core with insufficient bottom line is automatically taken down from the rotating shuttle, and the second shuttle core full of wound bottom lines is automatically replaced into the rotating shuttle, so that the sewing efficiency and sewing quality are improved.

Description

technical field

[0001] The invention relates to the field of sewing machines, in particular to an automatic shuttle changing device and an automatic shuttle changing method. Background technique
