Embodiment Construction

[0053] refer to figure 1 , The malfunction preventing device 10 is applied to, for example, an air jet loom using compressed air as a fluid for weft insertion.

[0054] In the air-jet loom, the weft yarn 14 wound in the yarn feeding body 12 is measured to a certain length by the length measuring storage device 16, and is engaged by the engaging pin device 18, and plays the role of the stored yarn feeding weft yarn. Its tip is guided into the main nozzle 20 .

[0055] The weft yarn introduced into the main nozzle 20 is loosened by the locking pin device 18 for a certain period of time, and is ejected together with the compressed air from the main nozzle 20, and then the weft is inserted into the warp yarn by the compressed air ejected from the plurality of sub nozzles 22. 24 openings.

[0056] The inserted weft yarn 14 beats up the weft at the fell of the woven fabric 28 by the reed 26, and is cut off by the cutter 30, and the weft yarn part that is connected to the length me...

Abstract

A malfunction preventing apparatus to prevent reduction in qualities of a woven fabric by restarting operation while the cause of suspension of a weaving machine being not repaired by an operator. The malfunction preventing apparatus memorizes at least either first information showing that normal rotation or reverse rotation operation to a rotation angle for removing a weft inserted just before suspension is not performed for the driving shaft of an opening apparatus after the suspension of the weaving machine by a detected signal from an abnormality detection sensor or second information showing that normal rotation or reverse rotation to the rotation angle of the operation start of the weaving machine and prevents the operation of the weaving machine when the first or the second information is memorized in inputting an operation command signal.

Description

technical field [0001] The invention relates to a device for preventing re-opening and malfunctioning after the loom is stopped due to abnormality such as weft broken automatic stop or warp broken stop. Background technique [0002] Regarding the loom, when the loom stops (stops) due to poor weft insertion or defective weft yarns and weft breakage caused by weft yarn defects such as weft yarn breakage, the operator is responsible for removing Restart the loom after repairing the cause of stoppage (stop cause) such as defective yarn or repairing broken yarn. [0003] In view of the above, the loom can generally be operated by operating the operation button (operation command switch) while the loom is stopped. Therefore, with regard to the conventional loom, even if the operator does not repair the loom, if the operation button is operated, the loom can be restarted as usual. In this case, the quality of the fabric decreases. Contents of the invention [0004] The object ...
