Abstract

The invention discloses a method for replacing a bobbin of a bobbin case. The bobbin is taken out from the bobbin case, a connecting line between the bobbin and the bobbin case is cut off, a residual line on the bobbin case is reserved, a slop line on the bobbin is removed, a new bottom line is wound on the bobbin, ends of the new bottom line are connected with ends of the residual line, and the bobbin is placed into the bobbin case for standby application. A bobbin taking mechanism and a knotting mechanism cooperate, so that the bobbin is taken, the new bottom line is wound and connected with the slop line, and the like. Therefore, the bobbin of the bobbin case is automatically replaced, special watch operation is omitted, and manpower cost is reduced.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a method for replacing a bobbin core for a bobbin case with respect to the bottom shuttle of the sewing machine. Background technique [0002] The base of the sewing machine is provided with a shuttle chamber, and a bobbin case is installed in the shuttle chamber, and a bobbin with a bobbin thread is installed in the bobbin case, and cooperates with machine needles to carry out sewing work. Because industrial sewing machines usually work non-stop, and the amount of thread wound on the bobbin is very small, the bobbin thread on the bobbin will run out every once in a while, so it is necessary to arrange special personnel to take care of and replace the bobbin with the bobbin thread wound on it. [0003] Patent name: A device used to replace the bobbin for looping threads on a sewing or embroidery machine. Patent No.: 200580011462.2 discloses a shuttle changing device. By grasping the bobbin cas...
