Picking method and apparatus for multicolor picking loom

A picking apparatus for a multicolor picking loom comprising:

• a selected signal generation unit which counts a picking number every rotation of the loom and outputs a weft selection signal and a number-of-rotations selection signal, both corresponding to the picking number;
• a drive unit which selects one from a plurality of preset patterns relating to the number of rotations of the loom which corresponds to the number-of-rotations selection signal and which drives the loom according to the selected pattern;
• and
• a picking control unit picking a weft corresponding to the weft selection signal, the picking control unit including:
• a picking condition setting device setting picking conditions which correspond to the selected weft and a change pattern in the number of rotations of the loom during the course of changing of the number of rotations, said picking conditions being stored so as to correspond to the weft selection signal and the number-of-rotations selection signal, and
• a main control unit selecting the corresponding picking condition from the picking condition setting device according to the number-of-rotations selection signal and the weft selection signal, both of which are received from the selection signal generating unit,
• whereby the selected weft is picked under the selected picking conditions.

A picking method of a multicolor picking loom in which first and second wefts are picked while changing the number of rotations of the loom according to which weft is desired to be selected, the method comprising;

• a preparing step preparing a weft selection signal and a number-of-rotations selection signal which correspond to a picking number in a selection signal generation unit;
• a setting step previously setting picking conditions corresponding to the weft to be selected and a change pattern in the number of rotations of the loom at a pickable phase in a picking condition setting device, said picking conditions being set to associate with the weft selection signal and the number-of-rotations selection signal;
• a counting step counting the picking number of the first and second wefts;
• a first outputting step outputting the weft selection signal and the number-of-rotations selection signal corresponding to the picking number to the picking condition setting device;
• and
• a selecting step selecting the corresponding picking condition from the picking conditions preset in the picking condition setting device,
• whereby the first and second wefts are picked based on the selected picking condition.
