Description

[Detailed description of the invention] Purpose of the invention (industrial application field) The invention forms a guide path for the weft yarn injected from the main nozzle for weft insertion by a row of weft guide members arranged in parallel on the slay. The present invention relates to a weft insertion guide device in a fluid jet loom.

(Prior Art) In general, weft yarns injected from a main weft insertion nozzle into a weft opening are transported by a number of weft guide members 2 erected on a slay 1 as shown in FIG.
The yarn is guided flying through the weft guide path S formed by the row of guide holes 2a. And weft guide passage S
A plurality of auxiliary nozzles 4 are erected at appropriate intervals along the weft guide path S between the reed 3 and the weft guide member 2 in order to assist the flight of the weft thread inserted into the weft weft. . The auxiliary nozzle 4 is arranged opposite to the open type weft guide member 2A having a large opening on the reed 3 side, and the injection hole 4a provided at the tip thereof is directed toward the weft guide path S side. The auxiliary fluid ejected from the injection hole 4a not only assists the flight of the weft yarn, but also affects flight stability, which influences the quality of the woven fabric. Therefore, it is necessary to adjust the timing of the jets sequentially performed in a relay manner from the main nozzle for weft insertion (not shown) in accordance with weaving conditions such as the weaving width of the woven fabric and the type of weft yarns.

The valves that control the fluid supply to the auxiliary nozzles 4 usually control the fluid supply using a plurality of auxiliary nozzles as one unit (hereinafter referred to as auxiliary nozzle group), and these valves are sequentially relay-like from the main nozzle side for weft insertion. The auxiliary fluid is jetted from the auxiliary nozzle 4 from the weft insertion main nozzle side to the side opposite to the weft insertion side in a relay manner in units of auxiliary nozzle groups. Therefore, a fluid pressure detector is connected to any one of the auxiliary nozzles in the auxiliary nozzle group, and while checking the injection pressure at the same nozzle, the opening/closing timing of the valve corresponding to the auxiliary nozzle group is adjusted. There is a problem that the guide members 2, 2A become an obstacle, making it difficult to find the auxiliary nozzle corresponding to the valve to be adjusted, and making the injection timing adjustment work complicated.

(Problems to be solved by the invention) In other words, it is difficult to find the auxiliary nozzle corresponding to the valve to be adjusted in a fluid jet loom in which a weft guide passage is formed by a row of weft guide members arranged in parallel on a slay. This is the object to be solved by the present invention, and by solving this problem, the injection timing adjustment work can be performed quickly and the operating rate of the loom can be increased.

(Means for solving the problem) In order to solve the above problem, in the present invention, a guide path for the weft ejected from the main nozzle for weft insertion is formed by a row of weft guide members arranged in parallel on the slay. A plurality of auxiliary nozzles are disposed in the weft insertion direction between the weft guide member and the reed to assist the flight of the weft thread inserted into the guide passage, and a plurality of auxiliary nozzles are provided to assist the flight of the weft thread inserted into the guide passage. In a fluid injection loom equipped with a plurality of valves that sequentially relay control fluid supply in the weft insertion direction, a weft guide member facing the auxiliary nozzle in the front-rear direction of the loom includes a valve that controls the auxiliary fluid supply to the nozzle. A marker has been set up to display the information.

(Function) That is, for example, by coloring the weft guide member that faces the auxiliary nozzle on the main nozzle side of the auxiliary nozzle group corresponding to each valve in the front-rear direction of the loom, weft thread guide members that correspond to the colored weft thread guide member can be colored. When adjusting the opening/closing timing of a valve that controls the supply of auxiliary fluid to an auxiliary nozzle, the auxiliary nozzle necessary for injection pressure measurement can be immediately found.

20 and 21 are attached and connected. Each of the valve mechanisms 17 to 21 is driven in synchronization with the rotation of the machine base, and the driving force of a machine base rotation drive source (not shown) is applied to a drive shaft 22 operatively connected to the same drive source. The signal is transmitted to a rotary valve (not shown) through an adjustment gear 24 which is tightened and fixed by a screw 23 so that the mounting angle position can be adjusted, and a valve gear 25 which is in mesh with the adjustment gear 24. The valve mechanism 17 is communicated with the main nozzle 14 via a supply pipe 17a, and the valve mechanisms 18 to 21 are connected to a base block for supporting a plurality of weft guide members 13 and an auxiliary nozzle 15, as shown in FIG. Fluid passages L in 26, 27, 28, 29
