Abstract
An automatic picking controlling method for automatically controlling the operation of at least the subnozzle groups in a jetting pattern selected on the basis of the actual running mode of a picked weft yarn is arranged such that a plurality of typical jetting patterns respectively corresponding to different running modes of the picked weft yarn for controlling at least the subnozzle groups are initially stored in a storage unit; the running mode of the picked weft yarn is detected in a detection step; a jetting pattern meeting the actual running mode selected from among those stored in the storage unit is read, and the operation of the subnozzle groups is controlled in accordance with the selected jetting pattern for a predetermined period of time.
Claims8
An automatic picking controlling method for controlling the picking operation of a picking device having a main nozzle for picking a weft yarn by a jet of fluid, and a plurality of subnozzles arranged in groups which assist a picked weft yarn for running along a running path by jets of fluid, the method comprising the following steps:
- a storing step for initially storing a plurality of accessible jetting patterns for each of the groups of the plurality of subnozzles, each of the patterns respectively corresponding to a running mode of the picked weft yarn;
- a detecting step for detecting the actual running mode of the picked weft yarn during a picking operation;
- a reading step for selectively reading a jetting pattern corresponding to the actual detected running mode selected from among the initially stored jetting patterns;
- and
- a controlling step for controlling the operation and duration of operation of the subnozzles according to the selected jetting pattern.
