Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic mop manufacturing apparatus. Conventionally, motsupu was manufactured by arranging a pair of left and right winding levers horizontally, and rotating a chain that rotates along the outer circumferential groove of each winding lever so that the outer chain of each winding lever runs in the same direction. The plier arm is used to wind the pile yarn across the left and right winding levers, and the sewing machine installed midway in the direction in which the wound pile yarn is fed passes the wound pile yarn between the winding levers. While cutting both ends of the wound pile thread using the cutters installed on the outside of the left and right take-up levers behind the sewing machine, the pile thread is sewn into a continuous strip by the sewing machine. I try to cut it into pieces the size of .

However, when sewing the pile thread wound on the left and right winding levers with a sewing machine,
Since the needle of the sewing machine passes through the pile thread, it has to temporarily stop the pile thread that is being fed sequentially, and the pile thread that is being fed at a constant speed has the disadvantage that the center part of it is stopped by the sewing machine needle and becomes tangled. .

In addition, when cutting both ends of the sewn winding pile yarn with a cutter, it is necessary to prevent damage to the chain that sends the winding pile yarn and the equipment due to contact with the cutter, and to cut the winding pile yarn at both ends with a cutter. Advanced manufacturing techniques are required to ensure that both ends do not pass through uncut.

The present invention has been made to eliminate the above-mentioned drawbacks, and when the sewing machine needle stops feeding the winding pile thread, the operation of the sewing machine needle and winding are adjusted so as not to feed the pile thread. The feed operation of the pile thread is synchronized to perform smooth sewing work, and the top and bottom of the outside of the take-up lever are extended outward so that the cutter faces the groove between the top and bottom protrusions. We have developed an automatic motsupu manufacturing device that pulls both ends of the advancing winding pile yarn to both sides to prevent the cutter from coming into contact with the chain, and also makes it possible to reliably cut both ends of the winding pile yarn. This is what we provide.
