When weft 5 needs to be introduced from the left side, the left grabbing component 2 extends rightwards, the first shuttle guide sleeve 2-2 positioned at the front end of the left rapier 2-1 is firstly sleeved with the left end of the shuttle guide piece 3-1 of the shuttle component until the second electromagnet 2-3 of the grabbing component is contacted with the first ferromagnetic shuttle cap 3-2 of the shuttle component 3, at the moment, the first electromagnet 1-2 in the shuttle box component 1 is controlled by an electric control system to be in a demagnetized state (non-adsorption state) outwards, at the moment, the magnetic attraction force between the first electromagnet 1-2 in the shuttle box and the shuttle guide piece 3-1 on the shuttle component 3 disappears, and the first electromagnet 1-2 in the shuttle box component 1 has no adsorption force on the shuttle; meanwhile, an electromagnetic head on the left grabbing component 2 is activated, so that an electromagnet II 2-3 at the front end of the left grabbing component 2 is in a magnetizing state (adsorption state), and a ferromagnetic shuttle cap I3-2 of the shuttle component 3 is attracted, so that a shuttle guide sleeve I2-2 on the left grabbing component and the left side of a shuttle guide sheet 3-1 are mutually spliced and combined, and the left grabbing component 2 firmly grabs the shuttle component 3 (the shuttle guide sheet 3-1 provides a certain supporting function); the left-hand gripper assembly 2 will pull the shuttle assembly 3 out of the shuttle box assembly 1. After the left rapier 2-1 and the right rapier 4-1 reach the weft insertion position, the left grabbing component 2 carries the shuttle component 3 to pass through the shed 6 and move to the shuttle taking position of the right grabbing component 4 of the loom. When the second shuttle guide sleeve 4-2 of the right grabbing component 4 is sleeved with the right end of the shuttle guide sheet 3-1 of the shuttle component 3 grabbed by the left grabbing component 2, the third electromagnet 4-3 of the right grabbing component 4 is contacted with the second ferromagnetic shuttle cap 3-3 on the shuttle component 3 grabbed by the left grabbing component 2, at the moment, the second electromagnet 2-3 on the left grabbing component 2 is externally shown in a demagnetizing state (non-adsorption state) under the control of an electric control system, the magnetic attraction between the second electromagnet 2-3 on the left grabbing component 2 and the first ferromagnetic shuttle cap 3-2 on the shuttle component 3 disappears, and the second electromagnet 2-3 on the left grabbing component 2 has no adsorption force on the first ferromagnetic shuttle cap 3-2 on the shuttle component 3; meanwhile, the electromagnetic head on the right grabbing component 4 is activated, the electromagnet III 4-3 of the right grabbing component 4 is in a magnetizing state (adsorption state), and attracts the ferromagnetic shuttle cap II 3-3 of the shuttle component 3, so that the shuttle guide sleeve II 4-2 on the right rapier and the right shuttle guide piece 3-1 are mutually spliced and combined, and the right grabbing component 4 firmly grabs the shuttle component 3 (the shuttle guide piece 3-1 provides a certain supporting function); the right-hand gripper assembly 4 is now completely pulled out of the shuttle assembly 3 from the left-hand gripper assembly 2. The shuttle assembly completes left and right connection, the left rapier and the right rapier retract, and left weft insertion is completed.
After left-side weft insertion is finished, the right-side grabbing component 4 reaches the shuttle box component 1, the shuttle component 3 is carried by the right-side grabbing component 4, and the shuttle component 3 is placed into the shuttle box component 1 along a shuttle groove. At the moment, the electromagnet III 4-3 at the front end of the right grabbing component 4 is in a demagnetizing state (non-adsorption state) and does not adsorb the ferromagnetic shuttle cap II 3-3 of the shuttle component 3 any more, so that the acting force on the right side of the shuttle guiding sleeve II 4-2 on the right rapier and the shuttle guiding piece 3-1 is not large; meanwhile, the electromagnet I1-2 in the shuttle box assembly 1 is controlled by the electric control system to be in a magnetizing state (adsorption state) outwards, magnetic attraction is generated between the electromagnet I1-2 in the shuttle box and the shuttle guiding sheet 3-1 on the shuttle assembly 3 at the moment, and the electromagnet I1-2 in the shuttle box assembly 1 is fixed in the shuttle box through the adsorption shuttle assembly 3; the right grabbing component 4 moves rightwards to be separated from the shuttle component, and finally the right rapier retracts to wait for the next weft insertion command.

After the left rapier 2-1 and the right rapier 4-1 reach the weft insertion position, the right grabbing component 4 carries the shuttle component 3 to pass through the shed 6 and move to the shuttle taking position of the grabbing component 2 on the left side of the loom. When the first shuttle guide sleeve 2-2 of the left grabbing component 2 is sleeved with the left end of the first shuttle guide tab 3-1 of the shuttle component 3 grabbed by the right grabbing component 4, and the second electromagnet 2-3 of the left grabbing component 2 is contacted with the first ferromagnetic shuttle cap 3-2 on the shuttle component 3 grabbed by the right grabbing component 4, under the control of an electric control system, the third electromagnet 4-3 on the right grabbing component 4 is in a demagnetizing state (non-adsorption state), the magnetic attraction between the third electromagnet 4-3 on the right grabbing component 4 and the second ferromagnetic shuttle cap 3-3 on the shuttle component 3 disappears, and the third electromagnet 4-3 on the right grabbing component 4 has no adsorption force on the second ferromagnetic shuttle cap 3-3 on the shuttle component 3; meanwhile, the electromagnetic head on the left grabbing component 2 is activated, the electromagnet II 2-3 of the left grabbing component 2 is in a magnetizing state (adsorption state), and the electromagnet cap I3-2 of the shuttle component 3 is attracted, so that the shuttle guide sleeve I2-2 on the left rapier and the left shuttle guide piece 3-1 are mutually spliced and combined, and the left grabbing component 2 firmly grabs the shuttle component 3 (the shuttle guide piece 3-1 provides a certain supporting function); the left-hand gripper assembly 2 is completely pulled out of the shuttle assembly 3 from the right-hand gripper assembly 4. The shuttle component completes left and right connection, the left rapier and the right rapier retract, and right weft insertion is completed.
After the right weft insertion is finished, the left grabbing component 2 reaches the shuttle box component 1, the left grabbing component 2 carries the shuttle component 3, and the shuttle component 3 is placed into the shuttle box component 1 along the shuttle groove. At the moment, the electromagnet II 2-3 at the front end of the right grabbing component 2 is in a demagnetizing state (non-adsorption state) and does not adsorb the ferromagnetic shuttle cap I3-2 of the shuttle component 3 any more, so that the acting force on the left side of the shuttle guiding sleeve I2-2 on the left rapier and the shuttle guiding piece 3-1 is not large; meanwhile, the electromagnet I1-2 in the shuttle box assembly 1 is controlled by the electric control system to be in a magnetizing state (adsorption state) outwards, magnetic attraction is generated between the electromagnet I1-2 in the shuttle box and the shuttle guiding sheet 3-1 on the shuttle assembly 3 at the moment, and the electromagnet I1-2 in the shuttle box assembly 1 is fixed in the shuttle box through the adsorption shuttle assembly 3; the left grabbing component 2 moves leftwards to be separated from the shuttle component, and finally the left rapier retracts to wait for the next weft insertion command.
