Abstract

The invention provides an automatic filling transfer device for the automatic filling transfer of a filling carrier which does not change the twist of a filling yarn and a filling transfer method thereof. The automatic filling transfer device comprises a rectangular base, a driving system, a control unit, and a filling carrier bank, wherein the control unit controls the driving system; the filling carrier bank can move to and fro on the base and is provided with two filling carrier positions; a disconnecting barrier is arranged at one end of one of the filling carrier positions; and the driving system can push the filling carrier bank to move on the base. The automatic filling transfer device is for the filling yarn having a rectangular section; the filling yarn is not allowed to change the twist in the filling insertion process; the filling yarn is timely and automatically supplied in the running process of a weaving machine, so that the weaving machine is surely prevented from beingstopped due to the lack of filling yarns in the filling carrier and can continuously run; and the running efficiency of the weaving machine is maximally improved, and the quality of weaved products is improved.

Description

technical field [0001] The invention relates to a weft changing device of a loom, in particular to an automatic weft changing device and a weft changing method thereof. Background technique [0002] At present, all kinds of shuttleless looms are fed by large packages of bobbin yarn, and the bobbin does not move, so the weft yarn between the new and old bobbins can be connected end to end, the weft insertion is continuous, and there is no need to change the weft during the weaving process; The weft insertion action during the operation of the loom is to hit the shuttle to make it fly in the weaving mouth. When the shuttle flies, the weft yarn is unwound axially from the tube head. The weft yarn on the old and new tubes cannot be connected. To make the loom run continuously, it must Automatically change the weft before the weft yarn on the bobbin is used up. There are two weft changing methods: automatic bobbin change and automatic shuttle change. The automatic bobbin change i...
