That is, the volume and mass of the nozzle housing that holds the four nozzles are increased, and the part of the nozzle housing may vibrate in the swing direction during high-speed operation accompanied by the swing motion of the reed holder.
In addition, as the number of nozzles increases, the size of the nozzle case increases, so the vibration of the part of the nozzle case also increases.
This vibration may lead to deterioration of the posture of the tip of the weft yarn during weft insertion, and poor weft insertion may occur.
In addition, if the vibration becomes large, the nozzle holder itself will move in the left and right direction, and weft insertion failure may occur.

[0026] based on Figure 1 ~ Figure 4 The first embodiment will be described. Also, in this manual, set figure 1 Below is the front of the loom as the weaving take-up side, set figure 1 The upper part of is described as the rear of the loom on the warp delivery side. In addition, set figure 1 The left side of the loom is the left side of the loom, the right side is the right side of the loom, and relative to figure 1 The direction perpendicular to the paper surface is the up-and-down direction of the loom, and the front side of the paper surface is defined as the upper side, and the back side of the paper surface is defined as the downward direction.
[0027] The main nozzle device 10 of the air jet loom is as figure 1 As shown, it is provided with: a plurality of main nozzles 11 for weft insertion; In addition, the sley 13 is provided in front of the air-jet loom, and is extended in the width direction (left-right direction) of the air-jet loom. A deformed reed 20 is he...

[0060] Next, based on Figure 5 , Image 6 The second embodiment will be described.
[0061] This embodiment is a case where an automatic weft yarn processing device is added to the main nozzle device 10 of the air jet loom of the first embodiment, and other configurations are common.
[0062] Therefore, here, for the convenience of description, some of the reference numerals used in the previous description are used in common, the description of the common structure is omitted, and only the changed parts will be described.
[0063] like Figure 5 and Image 6 As shown, the main nozzle device 50 of the second embodiment includes an automatic weft yarn processing device that automatically processes the weft yarn Y having poor weft insertion. A weft yarn introduction duct 51 is provided above the front end side of the main nozzle 11 for weft insertion, and a weft insertion prevention nozzle 52 is provided below the front end side of the main nozzle 11 for weft insertion. An...

Abstract
An object of the present invention is to provide a main nozzle device of an air jet loom capable of suppressing vibration of a main nozzle held by a nozzle holder by suppressing vibration in a swing direction of a nozzle holder holding a plurality of nozzles. The main nozzle device (10) of the air-jet loom has: 8 main nozzles (11 (11D, 11H)) for weft insertion; and the main bracket (14), the main bracket (14) has the main nozzle ( The nozzle holding part (12) held by the base end part of 11) is fixed on the sley (13); it swings integrally with the swing of the sley (13); in the main nozzle device (10) of the air jet loom , with an auxiliary bracket (22) connecting the nozzle holder (12) to the front side of the sley (13), cooperating with the main bracket (14) to restrain the nozzle holder (12) Vibration in the swing direction.
Description
technical field [0001] The present invention relates to a main nozzle device of an air jet loom provided with a plurality of main nozzles for weft insertion for weft insertion of a plurality of weft yarns. Background technique [0002] For example, Patent Document 1 discloses a nozzle device for weft insertion of a plurality of weft yarns of an air jet loom including a plurality of nozzles corresponding to a plurality of weft yarns. In this nozzle device, a nozzle holder fixed to a reed holder (sley) that moves integrally with the reed holds a plurality of nozzles, and the front ends of the nozzles are assembled and arranged. [0003] The nozzle holder is composed of a nozzle holder and a nozzle case, and the nozzle case is inserted and fixed into the through hole of the nozzle holder. In the nozzle housing, 4 weft insertion needle nozzles are inserted and fixed. The jet guide pipes are respectively connected to the front ends of the weft insertion needle nozzles via throt...
