Problems solved by technology

The entire operation process of taking out the bobbin from the bobbin case, replacing the bobbin thread on the bobbin, and putting the bobbin into the bobbin case is very cumbersome, especially when the bobbin is installed in the bobbin case, it is necessary to find the end of the bobbin thread on the bobbin, and then insert it into the bobbin case. The end of the thread is stuck into the seam of the bobbin case, and the end of the thread is passed through the thread hole on the bobbin case. This operation step can only be realized manually, resulting in low efficiency of bobbin replacement

Abstract

The invention discloses a bobbin taking mechanism of an automatic shuttle replacing device. The bobbin taking mechanism comprises a base capable of sliding forward and backward, a rotatable winding shaft and a winding motor connected with the winding shaft are arranged on the base, and a pneumatic sucker for adsorbing a bobbin is arranged on the winding shaft. The bobbin taking mechanism can automatically take out the bobbin from a bobbin case or place the bobbin with a wound new bottom line into the bobbin case under driving of the base, and a mounting plate is arranged on the base and driven by a first telescopic cylinder. When the bobbin is taken out, the pneumatic sucker can be driven to be close to the bobbin and suck the side wall of the bobbin, and bobbin clamping jaws can be driven to lock the side wall of the bobbin. When the bobbin is placed into the bobbin case, the bobbin clamping jaws are driven to open, and the pneumatic sucker is driven to eject the bobbin into the bobbin case.

Description

technical field [0001] The invention relates to an automatic shuttle changing device of a sewing machine, in particular to a bobbin-taking mechanism for the automatic shuttle changing device. 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 case co...
