Electromagnetic weft insertion weft carrier, rapier for electromagnetic weft insertion as well as electromagnetic weft insertion method

Abstract

The invention provides an electromagnetic weft insertion weft carrier with high efficiency of weft inserting and weaving, an electromagnetic weft insertion device and an electromagnetic weft insertion method. The electromagnetic weft insertion weft carrier provided by the invention comprises a shuttle box and a yarn storage device arranged in the shuttle box, wherein two corresponding side walls of the shuttle box are respectively provided with a permanent magnet used for electromagnetic weft insertion and at least one locating hole. According to the electromagnetic weft insertion weft carrier, a rapier for the electromagnetic weft insertion, and the electromagnetic weft insertion method provided by the invention, no an additional shuttle path is needed, the weft carrier is moved in the air by using an electromagnetic action and always in a controlled state so that the weft carrier is prevented from being hit, free flight of the weft carrier is prevented, and the service life of the weft carrier, success rate of weft insertion and weaving efficiency are all increased; in addition, the weft insertion device has the advantages of simple structure and convenience for operation.

Description

technical field [0001] The invention relates to a loom weft carrier, a weft insertion device and a weft insertion method, in particular to an electromagnetic weft insertion weft carrier, a rapier for electromagnetic weft insertion and an electromagnetic weft insertion method. Background technique [0002] The weft insertion method of the currently used shuttle loom is to set a shed on the loom, and hit the shuttle (weft carrier) to make it slide back and forth in the shed. In this weft insertion method, the shuttle is in free flight during movement. state, so the shuttle has a phenomenon of flying away from the shed, which reduces the success rate of weft insertion and the efficiency of weaving. At the same time, repeatedly hitting the shuttle will also reduce the service life of the shuttle. [0003] In addition, the patent No. ZL9510658.5, which is called the weft insertion method and device of the rapier loom, discloses a method of using electromagnetic force to open the ...

Problems solved by technology

[0002] The weft insertion method of the currently used shuttle loom is to set a shed on the loom, and hit the shuttle (weft carrier) to make it slide back and forth in the shed. In this weft insertion method, the shuttle is in free flight during movement. State, so the shuttle has a phenomenon of flying off the shed, which reduces the success rate of weft insertion and weaving efficiency. At the same time, repeatedly hitting the shuttle will also reduce the service life of the shuttle.
