Embodiment Construction

[0057] Below, based on Figure 1 to Figure 5 One embodiment of the present invention will be described. In addition, in this embodiment, the effective period of weft insertion is expressed as follows: the start point and the end point are obtained, and the effective period of weft insertion is obtained from the obtained start point and end point of the effective period of weft insertion.

[0058] figure 1 The overall structure of the water jet loom 1 is schematically shown. In the water-jet loom 1, after a plurality of warp yarns 3 sent out from the warp beam 2 in a wide shape are turned toward the cloth fell 10 by the back roller 13, they are respectively inserted through a plurality of heald frames 5 installed on the warp yarn shedding device 4. A plurality of unillustrated healds are connected to the cloth fell 10 via the reed 9 on the beating device 8 . In addition, as shown in the figure, in the water jet loom 1 based on the present invention, the warp shedding device ...

Abstract

The utility model discloses a display device for weft insertion information of a water jet loom. The display device can provide the weft insertion information for operators in the water jet loom with a weft insertion mouth fixedly arranged on a loom frame, wherein the weft insertion information serves as the reference information (indexes) of adjustment work. The display device is technically characterized in that the flight track of weft yarn and a graph related to the swing track of a reed are coincidentally displayed on a graphical area with the horizontal axis of a display frame as the rotation angle of a main shaft of the loom, then the earliest end time during the valid weft insertion period when the weft yarn is effectively conveyed by jetting water is worked out, and the worked-out end time can be displayed on the display frame in the mode that the rotation angle of the main shaft can be mastered.

Description

technical field [0001] The present invention relates to a method and a device for displaying weft insertion information of a water jet loom that injects weft yarns from a weft injection nozzle fixedly arranged on a loom frame. Background technique [0002] Generally, in a water jet loom, as disclosed in Patent Document 1, the weft inserting nozzle is fixedly arranged on the loom frame. And, the weft yarn is inserted into the warp yarn opening formed by separating the warp yarn group into upper warp yarn and lower warp yarn by the heald frame with the jet water sprayed from the weft injection nozzle, thereby performing the process of flying (transporting) the weft yarn to the reverse feeding yarn side. Weft insertion. In addition, after the weft insertion is completed, the weft yarn inserted is driven into the cloth fell by the reed oscillating in the warp direction, thereby completing one weaving operation (one cycle of the loom). In addition, the "warp direction" referred...
