V. Description of the invention (1) The present invention relates to a position adjuster for a weft insertion nozzle on a fluid jet loom. More specifically, it relates to the use of a water jet loom. On the main nozzle to improve the adjustment of the fluid ejection direction. When operating a fluid jet loom, such as a water jet loom, the quality of the fabric to be woven and the operating efficiency of the loom are significantly dominated by the stability of weft insertion. As a result, in order to ensure stable weft insertion, it is extremely necessary to maintain the weft insertion nozzle. The fluid ejection direction is correctly designed. In the field of the textile industry, the continuous pursuit of an infinite increase in the operating speed of the weaving machine is required. "In order to increase the operating speed of the weaving machine, we must design the shed as small as possible, and at the same time successfully avoid nasty yarn breaks and yarn loosening. . In addition, increasing looms are required in order to efficiently produce fabrics. In order to fully meet these requirements, the flying weft must pass smoothly through the shed. The main nozzle deviates from the standard position (due to the main nozzle deviating from the standard line), the corresponding weft nozzle is offset. Even a small offset in the nozzle position can produce a large offset in the weft course, because when the weft yarn passes through a long shed, the initial offset of the weft course increases and expands. This offset of the weft thread makes the smooth weft scraping severely ineffective. For this reason, the correct position adjustment of the weft insertion nozzle is extremely needed. An earlier technique for this position adjustment of the main nozzle is disclosed in Japanese Utility Model Publication Sho. 49-27822. In the construction of this earlier technique, the spherical protrusions of the nozzle holder block holding the main nozzle are combined with the spherical recesses in the carrier block and the adjuster bolts are screwed through the carrier block to make each point It is in abutment with a conical seat formed on a support block. This paper size applies to Chinese National Standard (CNS) A4 specification (210X297mm) -------- r --- installation ----- 1T ------ ^ (Please read the Note for refilling this page)--~ 4-Consumption cooperation by the Central Bureau of Standards of the Ministry of Economic Affairs, printed 497171 __B7 V. Description of the invention (2) Regarding the adjustment of the position of the main nozzle, the adjuster bolts are rotated differently so that they have Different embedding lengths pass through the carrier block. This different rotation of the adjuster bolt changes the joint angle of the nozzle holder block with respect to the carrier block to adjust the position of the main nozzle fixed by the nozzle holder block. However, in the case of this earlier technique of covering the position adjuster, the use of many components such as a bracket block, a carrier block, and an adjuster bolt resulted in a large and heavy structure. During the adjustment process, many adjuster bolts must be rotated in a subtle relationship, while paying attention to the change in the position of the main nozzle. This operation is extremely complicated and its application requires advanced technology. The adjustment process is based on the combination of the tapered seat and each adjuster bolt. This process limits the freedom to adjust a wide range. In the nozzle displacement system disclosed in Japanese Laid-Open Patent Sho. 49 — 41671, a single nozzle position is provided for common use of a plurality of main nozzles. On a certain degree of weft insertion, a main nozzle corresponding to the cycle is selectively moved to a common nozzle position. When the above-mentioned type of position adjustment is applied to this nozzle shifting system, different nozzles need different position adjustments that are independent of each other, making the entire structure extremely heavy and large, and the operation is extremely complicated. That is, since many main nozzles are used, the disadvantages faced when using a single main nozzle are enlarged. As a result, the above-mentioned position adjustment is very unsuitable for general-purpose applications.

A fifth specific embodiment of the position adjuster is shown in FIG. 8 and FIG. 10, in which a position adjuster is used for the main nozzle system, such as disclosed in the aforementioned Japanese published patent s ho49_41 671. The system includes a plurality of main nozzles A common nozzle position, and during a certain weft insertion cycle, a main nozzle corresponding to the cycle is selectively aligned at the nozzle position. The illustrated construction doubles the construction shown in Figs. 7 and 9 and is used for multicolor weaving, where two different kinds of weft yarns are used.

Description of the invention (10) Tube 4 One of the flow paths and the coupling section 1 a of the bracket assembly 1 communicate with each other. The vibration of the bracket assembly 1 will not cause any change in the physical condition of each flow path. Similarly, the second main nozzle 7 b is supported by the bracket block 5 b, and 5 b is coupled to the bracket through the bushing 3 b. 1 b. A spherical coupling exists between the bushing 3b and the frame 1b. The bracket 1 b is swingably supported by a bracket bracket 6 b. The cradle bracket 6b is associated with a tube 4b connected to a spray fluid supply source (not shown). The flow path formed by the bracket support 6 b includes a flow path communicating with the tube 4 b and the coupling section lb of the bracket assembly 1. The vibration of the cradle assembly 1 does not cause any change in the physical condition of each flow path. The drive assembly 8 for the swing movement of the carriage assembly 1 is composed of a drive shaft 81, a crank pin 83, a crank 86, and a swing lever 87. The crank pin 83 is suitable for fastening the drive shaft 81 and the crank 86 is hinged to one end of the crank pin 83. The drive shaft 81, the crank pin 83 and the crank 86 thus form a crank mechanism. The crank 8 6 (on one terminal) is connected to the yaw lever 8 7, which is fastened to the connecting section 1 c of the bracket assembly 1. With this structure, the rotation of the drive shaft 81 causes the swing movement of the bracket assembly 1 via the crank mechanism and the swing lever 87. In order to make the rotation of the driving shaft 81 consistent with the weft insertion, the driving source (not shown) of the driving shaft 81 includes a well-known driving device such as a driving motor. Prior to weft insertion, the carriage unit 1 is driven to swing and stop just before weft insertion is started to align one of the main nozzles of the cycle at the nozzle position, and the carriage assembly 1 can be directly connected to or Pass a paper size using Chinese National Standard (CNS) A4 (210X 297mm) (Please read the notes on the back and fill in the dream page) Printed by the Consumers Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs W7171 DESCRIPTION OF THE INVENTION (u) is connected to a drive motor. It is also possible to attach the bracket assembly 1 to an interface, for example via a cam on the main shaft of a loom. The drive system of the above-mentioned carrier assembly 1 is implemented based on the weft selection command, and the carrier assembly system is driven at each moment of the weft shift so as to swing and move. When the displacement of the weft-free yarn starts, the bracket assembly and position remain unchanged. When driven, the bracket assembly swings to align a selected main nozzle at the nozzle position for subsequent weft insertion. The bracket and the combination of the bracket assembly and the bracket block, and the distribution of the spherical coupling can be designed in various ways as shown in Figs. In any of the illustrated arrangements, the bracket or bracket assembly is connected to the drive assembly 8. In the case of the specific embodiment shown in FIG. 11, the bracket assembly 1 surrounds the support block 5, and a spherical coupling 2 is positioned close to the central axis of the bracket assembly 1. This design is suitable for a loom High-speed operation because the inertia of the movement of the main nozzle 7 is relatively small. In the case of the specific embodiment shown in FIG. 12, the bracket block 5 surrounds the bracket assembly 1 and separates the positioning of the spherical coupling 2 from the central axis of the bracket assembly 1. As a result, the main nozzle The moving inertia of 7 is quite large, and the system is not suitable for high-speed operation of the loom. In the case of the specific embodiment shown in FIG. 13, the bracket assembly 1 surrounds the bracket block 5 and positions the spherical coupling 2 The central axis of the bracket assembly 1 is approached. Since the movement inertia of the main nozzle 7 is relatively small, this system is suitable for high-speed operation of the loom. In the case of the specific embodiment shown in FIG. 14, the paper size of the bracket assembly is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) H .-- Public-- (Please read the (Notes to refill, page.)

Description of the invention (12) Also surrounds the bracket block 5 and locates and couples the spherical coupling 2 The center axis of the rack assembly 1 is separated. Since the movement inertia of the main nozzle 7 is quite large, this system is not suitable for high-speed operation of the loom. In the case of each of the foregoing specific embodiments, the flow path of the fluid communicating to the tubular storage tank in the main nozzle is formed in the support block. This flow path / path can also be formed directly to the main nozzle via a separate tube. For easier position adjustment, take an appropriate scale, for example, the angular scale is marked in a spherical convex or concave shape. In order to adjust the position with a small force, an arm can be attached to the main nozzle. With this kind of arm, the position of the main nozzle can be adjusted without any direct contact with the main nozzle. Although the water jet weft weaving loom is exemplified in the foregoing description, the present invention is similarly applicable to other types of fluid jet loom, such as an air jet weft loom with a simple modification well known to those skilled in the art. In the foregoing description, the bracket assembly hip refers to a combination including a bracket itself and a drive shaft coupled thereto. In the case of the foregoing specific embodiments, a bushing is interposed between each of the bracket blocks and the bracket assembly. However, in the simplest design, each bracket block can be directly combined with the bracket assembly via a ball coupling. According to the present invention, the use of a spherical coupling to support the weft insertion nozzle greatly increases the freedom of position adjustment. In addition, the position adjustment can be easily performed only by adjusting the support block that supports the weft insertion nozzle. When the flow path of the ejection fluid is formed in the support block and the bracket or the bracket assembly, the separate flow path element is no longer used, thereby simplifying the structure even further. ------- ：-Select ------ 1T ------ ^ (Please read the notes on the back before filling this page)--This paper size is applicable to Chinese countries 梂 芈 ( CNS) A4 specification (210X297mm) Consumer cooperation of the Central Bureau of Standards of the Ministry of Economic Affairs of the People's Republic of China Du Qinqi _4QZ171_ V.
