Claims

[Scope of Claim for Utility Model Registration] (1) Drive of a locking pin that controls the locking and unwinding of the weft by moving in and out of the circumferential surface of the weft storage drum at appropriate timings using a solenoid drive In the device, when the coil 23 is energized and the iron core 20 is advanced most forward into the cavity 24 in the coil, a clearance is defined and formed between the tapered part 21 at the tip of the iron core and the tapered part 26 in the coil cavity. A locking pin drive device for a weft storage device in a shuttleless loom, characterized in that an iron core is arranged so that the width of α can be changed freely. (2) Due to coil excitation, the iron core 20 moves into the coil cavity 2.
When the iron core moves forward most in the four directions, a spring holder 17 to which the iron core is integrally attached to prevent the iron core from moving further comes into contact with a core stopper 19, and the iron core stopper 19 accommodates the coil 23. The device according to claim (1) of the utility model registration, characterized in that the device is screwed onto a solenoid case 30 so that the degree of screwing can be adjusted. (3) When the core 20b moves forward toward the coil inner space 21 due to coil excitation, the core 20b is screwed into the spring holder 17b that comes into contact with the core stopper 19b in order to prevent the core from advancing further. Utility model registration claim No. (1) characterized in that the utility model is adjustable and screwed together.
