DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet loom having a jet action adjusting means for inserting a weft by the action of an ejection fluid and adjusting the ejection action of the ejection fluid acting on the weft every time the weft is inserted. The present invention relates to an injection action adjustment instruction device.

[0002]

2. Description of the Related Art In a jet loom in which weft is inserted by jetting compressed air from a weft insertion nozzle, the weft insertion state largely depends on the pressure setting of the compressed air. Therefore, it is necessary to set a pressure suitable for the weft at the trial weaving stage.

[0003] Generally, the weft inserted is measured by a winding type weft measuring and storing device. When the inserted weft yarn is cut for each beating, the wound yarn wound and stored on the yarn winding surface of the weft length measuring and storing device is danced by the cutting shock, and the good quality from the yarn winding surface is improved. There is a possibility that weft unwinding cannot be performed. For this reason, when cutting the weft every beating, air is jetted from the weft insertion main nozzle that injects the weft into the warp shedding so that the cutting shock does not spread to the weft length measuring and storing device side. . It is necessary to set the injection pressure appropriately in advance.

In order to properly set the injection pressure at the weft insertion nozzle, it is necessary to grasp the flying state of the weft inserted weft. Therefore, as disclosed in Japanese Patent Publication No. 64-3969, the arrival time of the weft leading end at the weft insertion end is detected, or as disclosed in Japanese Utility Model Publication No. Sho 63-24147, the solution is pulled out from the weft length storage device. Detecting the end time information of the predetermined weft unwinding amount of the weft to be wound is performed. The operator performs the work of setting the injection pressure appropriately based on the detected information.

[0005]

However, for an operator who cannot grasp the meaning of the detection information reflecting the flight state of the weft, adjustment for proper setting of the injection pressure to achieve good weft insertion is performed. I can't work.

[0006] In addition, a worker who does not know how to properly set the injection pressure so that the cutting shock when the weft is cut does not spread to the weft length measuring and storing device side, can take a good weft withdrawal unwinding. It is not possible to perform adjustment work for setting the injection pressure properly to achieve it.

An object of the present invention is to make it possible for any worker to easily set an appropriate injection action such as an injection pressure and an injection timing.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, a behavior detecting means for detecting a behavior of a weft, and a determination as to whether or not an adjustment mode of an injection action adjusting means is appropriate based on a detection result of the behavior detecting means. In addition, an injection action adjustment instructing device is provided that includes an adjustment mode determining unit that outputs adjustment instruction information based on the determination result, and a notifying unit that notifies the adjustment instruction information output by the adjustment mode determining unit.

The adjustment mode determining means determines whether the adjustment mode of the injection action adjusting means is appropriate based on the detection result of the behavior detecting means. If the adjustment mode of the injection action adjusting means is appropriate, the notifying means notifies that the adjustment mode is appropriate. If the adjustment mode of the injection action adjusting means is not appropriate, the notifying means notifies adjustment instruction information for providing an appropriate adjustment mode. When the operator adjusts the injection action adjusting means in accordance with the notified adjustment instruction information, the adjustment mode of the injection action adjusting means shifts to an appropriate state. Therefore,
Any worker can easily set an appropriate injection action.

In the invention according to claim 2, the injection pressure adjusting means for adjusting the injection pressure of the injection fluid is the injection action adjusting means. According to the third aspect of the invention, the injection timing adjusting means for adjusting the injection timing of the injection fluid is the injection action adjusting means.

In the invention of claim 4, the flight timing detecting means for detecting the flight timing of the weft during weft insertion is the behavior detecting means. The adjustment mode determination means determines whether the adjustment mode of the injection action adjustment means is appropriate based on the flight timing detected by the flight timing detection means.

In the invention according to claim 5, the display means for displaying the determination result is the notification means. The display means displays an indication that the adjustment mode is appropriate, or displays adjustment instruction information for providing an appropriate adjustment mode.

According to the invention of claim 6, the behavior display means for displaying a predetermined proper behavior of the weft, and the adjustment instruction information of the injection action adjusting means for providing the proper behavior displayed by the behavior display means are provided. An injection action adjustment instructing device including an informing means for informing is configured.

If the operator adjusts the injection action adjusting means according to the adjustment instruction information notified by the notifying means,
The behavior of the weft can be matched to the display content of the behavior display means. Therefore, any worker can easily set an appropriate injection action.

According to a seventh aspect of the present invention, there is provided a jet loom for measuring the length of a weft yarn by a winding type weft length storage device,
The proper storage state of the stored winding yarn in the weft length measuring and storing device is displayed by the behavior display means, and when the inserted weft is cut and separated from the main nozzle for weft insertion at each weft insertion, the jet is injected from the main nozzle for weft insertion. The ejection pressure adjusting means for adjusting the ejection pressure of the ejection fluid to be used is the ejection action adjusting means.

If the operator adjusts the injection pressure adjusting means in accordance with the adjustment instruction information notified by the notifying means, the storage state of the stored winding yarn in the weft measuring and storing device can be adjusted to the content displayed on the behavior display means. . Therefore, any worker can easily set an appropriate injection action.
