Abstract
The invention relates to a pick finding mechanism for a loom. A main motor is connected with a loom spindle through a reduction transmission mechanism and a clutch brake mechanism. Through a transmission member, the loom spindle drives a warp shedding mechanism controlled via electronic signals and a pick selecting mechanism controlled via electronic signals. The transmission member comprises a synchronous belt and a pulley, or a sprocket and a chain, or a reversing gear and a vertical shaft. A computer numerical control let-off and computer numerical control take-up signal collecting mechanism is connected to the loom spindle or a shaft, which is synchronous with the loom spindle, and is connected with both a take-up mechanism and a let-off mechanism through an electrical control box. A signal generator of a finding key point signal mechanism is disposed on the loom spindle or a shaft in motion sync with the loom spindle. After a loom experiences a pick fault, namely pick breakage, and stops, during shedding, pick-selecting, letting-off and taking-up, the loom can go back to a broken pick to find the pick without a separating and re-meshing mechanism.
