Abstract
A monitoring system for the shuttle movements in a loom of the multiple moving shuttle type. Sensors are located at the end of shuttle travel through the shed, at the beginning and end of its recycling travel back to the transporting drum, and phase sensors are provided to indicate proper position of the transporting drum. Whenever any of the sensors detects a fault in the position or phase of the shuttle or transporting drum, the fault is indicated and the loom is normally shut down until the fault is cleared.
Claims4
A loom having a monitoring system, said loom being of the type having a weft bobbin located outside the shed, the weft is fed into the shed by means of shuttles which are brought into a shooting position by a rotary transporting drum, said shuttles being braked after passing through the shed carrying the weft, said shuttles pass through a chute from the braking means to a conveyor belt and are then returned to the transporting drum by the conveyor belt, the operation of said shuttles and the position in the cylical path of each shuttle being monitored by said monitoring system which comprises:
- first sensing means in said braking means for determining the position of said shuttle after passing through said shed;
- second sensing means in said chute for determining the position of said shuttle at the beginning of its return movement;
- third sensing means adjacent said transporting drum for determining the presence of said shuttle at the end of its return movement;
- and
- fourth sensing means for detecting the rotational phase of said transporting drum with respect to the loom movement.
