Abstract:
A shedding controlling apparatus for a loom is disclosed wherein each of a plurality of heald frames is driven by a drive motor for the exclusive use therefor. During steady operation of the loom, when a crank angle ( theta ) is inputted to a position instructing section (10), the position instructing section (10) produces an aimed amount (P0) of rotation, and a position controlling section (20) controls the drive motor (M) to rotate in accordance with the aimed amount (P0) of rotation to eliminate a deviation ( DELTA P) thereof from a crank shaft A of the loom to establish a synchronized relationship between them. Then, when an operation instruction signal (S6) is generated during stopping of the loom, movement instructing means (40) drives the drive motor (M) by a predetermined amount of rotation by way of an OR gate (10a) and the position controlling section (20) in accordance with a shedding pattern (Ksy) designated by way of shedding instructing means (50) and shedding pattern instructing means (30) so that a leveling operation of the heald frame, a pick finding operation and a starting preparing operation may be performed automatically.
