Description of the invention (2) A hose receiving portion 15 is formed at the end of the screw connection side and the opposite side of the pipe connecting body 4, and a sleeve receiving portion 16 is formed at the end edge in a push shape. With regard to the hose 6 connected to the main body 12 having such a structure, first, the front end of the hose 6 is inserted into the hose receiving portion 15 and the upper portion thereof is inserted into the sleeve 1 having the push-out protrusion 17. 8.

[Problems to be Solved by the Invention] The compressed air supply device in the air-jet loom is composed of a main injection part and an auxiliary injection part provided on a yarn dividing rod that swings forward and backward in the loom, from below the yarn dividing rod. The compressed air supply source provided on the frame side of the loom is used to supply compressed air through valves and hoses. However, other components of the weaving loom are also provided on the lower side of the yarn dividing rod, which makes the space limited and narrow, and because the compressed air supply source or valve is located far from the yarn dividing rod, it is connected to the main injection. The length of the hoses of the auxiliary injection section and the auxiliary injection section is long, which results in an increase in the pressure loss of compressed air and an increase in energy consumption, etc., and the air reactivity of the main injection section and the auxiliary injection section also results in the stopping reactivity. Deterioration makes the weft knitting function lower. For this reason, the compressed air supply device must be effectively located in a limited and narrow space below the yarn separating rod. In contrast, in the aforementioned conventional technology, the hose 6 is connected to the hose connecting body 4 via the main body 12, so that the degree of freedom of the piping is limited only by the height of the main body, as shown in FIG. 4 In the narrow area, the hose 6 has to be bent in the remaining space, so that the hose 6 is excessively bent and loses margin, resulting in durability 508385. V. Problems in the description of the invention (3), as shown in the figure As shown in area A, the adjacent hoses 6 interfere with each other, causing problems that cause damage, or because the hose connector 4 is first installed on the main body 12 and then the hoses are connected, causing More time-consuming problems in assembly. The present invention has been made focusing on the problems existing in the conventional techniques described above. The purpose is to provide a compressed air supply device for the main injection section or the auxiliary injection section, which can be installed with a considerable margin even in a narrow and narrow area like an air jet loom. [Means for solving the problem] In order to achieve the above-mentioned purpose, in the invention of the compressed air supply device in the air-jet loom described in item 1 of the scope of patent application, a main injection is provided on the yarn dividing rod that swings forward and backward in the loom The air-jet loom of the engine and the auxiliary injection unit is provided with a fluid passage for circulating compressed air supplied from a compressed air source and controlled by a valve; and a plurality of distribution fluid passages for the fluid Those who are diverted by the passage for supplying compressed air; and have a body formed by a hose connection body or a valve; a stopper plug-in portion is formed in the distribution fluid passage, and the main injection portion or the auxiliary injection portion is ejected. The other end of the hose connected to one end of the tube, the sleeve fitted to the outer peripheral edge, and the stopper fitted to the outer circumference of the sleeve are inserted into the distribution fluid passage, and the stopper is used for the distribution. The stopper of the fluid passage is bolted and fixed inside, and is connected with the body, the hose, the sleeve, and the stopper.

Explanation of the invention (5) Therefore, according to the present invention, the invention described in item 1 or 2 of the above-mentioned patent application scope is added. On the external open side of the aforesaid stopper, while increasing the degree of freedom of the hose, It can suppress the sharp bending of the hose, and the hose body can be set in a non-compressive state. In the invention of the compressed air supply device in the air-jet loom described in item 4 of the scope of the patent application, the invention described in item 1 or 2 of the scope of the patent application is added, and the aforementioned body and the device for controlling compressed air are added. For those who integrate the valve. Therefore, according to the present invention, the position of the valve can be close to the side of the main injection portion and the auxiliary injection portion, and since the length between the valve and the injection portion can be shortened, the pressure loss of the compressed air in the hose can be reduced. , And can form a compressed air injection control with better sensitivity. In the invention of the compressed air supply device in the air jet loom described in item 5 of the patent application scope, the invention described in item 1 or 2 of the above patent application scope is added, and the aforementioned body is used as a hose connected to the valve Connectors. Therefore, according to the present invention, it is possible to respond immediately to a change in the number of injection portions or a change in the opening position of the fluid passage for distribution, etc. by simply changing the hose connection body. [Detailed description of the preferred embodiment of the present invention] (First embodiment) Hereinafter, the first embodiment of the present invention will be described in detail based on Figs. 1 and 2. V. Description of the invention (6) As shown in FIG. 1, the main injection portion 31 for ejecting the weft yarn γ and a plurality of ejected compressed air for accelerating the weft yarn Y in the ejection diagram (only in the first diagram) The figure shows 8) auxiliary spraying sections 32, which are installed on the yarn separating rod (not shown). A group of auxiliary injection sections 32a, 32b formed by an appropriate number of auxiliary injection sections 32 (four in this embodiment) will be respectively included in this group as hose connection bodies 33 for compressed air distributors. Installed on the frame side of the machine. The hose connector 33 is integrally integrated with a valve 34 for controlling the supply of compressed air by a compressed air source (not shown). A fluid passage 37 communicating with the valve 34 and a distribution fluid passage 51 corresponding to each of the auxiliary injection portions 32 are branched in the hose connecting body 33 as shown in FIG. 2. Each auxiliary injection portion 32 and the hose connecting body 33 are connected by a flexible hose 35 and a piping joint 36. In the above-mentioned distribution fluid passage 51, a hose insertion portion 39, a sleeve receiving portion 40, and a stopper insertion portion 41 are sequentially formed in the inside thereof. The sleeve 42 which is externally inserted into the hose 35 is provided with a push-out projection 43 at the front end, and a push-out portion 44 which is connected to the push-out surface as the sleeve receiving portion 40 at the front end. The rear end portion is formed with a pushing surface as a bolting portion 45 described later. Reference numeral 46 is a bolt-shaped stopper having a through-hole 47 in the shaft center portion. The hexagonal head 48 can be locked by a tool, and the stopper 46 can be locked and fixed to the stopper insertion portion 41. A receiving portion 49 is formed on the inner peripheral portion of the front end of the through hole 47 of the stopper 46 to be joined to the bolting portion 45 of the sleeve 42 described above. 5. Description of the invention (7) Next, the assembling method of the piping joint constructed as described above will be described. First, the front end portion of the hose 35 is inserted into the hose insertion portion 39, and a sleeve 42 is inserted from above, and the pushing surface 44 of the sleeve 42 is engaged with the pushing receiving portion 40 to fall. Into the distribution fluid passage 51. After that, the abutment tool 46 which is externally inserted into the sleeve 42 is locked into the abutment tool insertion section 41. At this time, the accommodating portion 49 on the inner peripheral portion of the front end of the stopper 46 is engaged with the bolt portion 45, and the sleeve 42 is pressed and braked toward the hose insertion portion 39 side. With this compressive braking action, the pushing portion 44 at the front end of the sleeve 42 is pressed against the sleeve receiving portion 40. The pressing reaction force acting on the pushing surface of the sleeve receiving portion 40 causes the pushing protrusion 43 at the front end of the sleeve 42 to decrease in the radial direction. As a result, an airtight state between the hose 35 and the sleeve 43 and between the hose insertion portion 39 can be ensured. Here, the substantial connection portion of the piping joint 36 forms the internal shape accommodated by the hose connection body 33, and only the portion near the hexagonal head portion 48 of the stopper 46 protrudes outward. As a result, as shown in Fig. 1, in addition to not restricting the piping connector excessively, the hose 35 can be piped with a large curvature margin. The following description is to achieve the desired effects by the above-mentioned embodiment. (a) Even in a rather narrow and limited area like the compressed air heat supply place of the main injection section or the auxiliary injection section of the air-jet loom, the hose 35 is constantly stopped due to the swinging action of the spinning rod. In the area affected by the shaking, since the piping can obtain a large degree of freedom, a holding margin of 508385 is formed. V. Piping of the invention description (8), thereby avoiding interference between the hoses 3 and 5, which makes it possible to Prevent mutual damage in advance. (b) Since a piping with a margin can be formed, the curvature of the hose can be maintained at the maximum for piping, thereby reducing the burden on the hose 35, and the result contributes to the improvement of durability. (c) Because the main body of the conventional device is omitted, in addition to reducing the cost by reducing the number of parts, it also helps to reduce the number of assembly workers. (d) The valve 34 for controlling the compressed air supplied from a compressed air source (not shown) is directly connected to the hose connecting body 33 to form an integrated structure, so the position of the valve 34 can be set It is close to the main injection part or the auxiliary injection part, and because the hose 35 can be shortened, it is possible to form the injection control of compressed air with the better sensitivity of the auxiliary setting part. In addition, the pressure loss in the hose 35 is reduced. Can also help save energy. (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to Fig. 3. It is basically the same as the first embodiment. In such an embodiment, the tail portion of the sleeve 42 is relatively short, and a tapered inclined surface 50 is provided at the outer open side end portion of the through hole 47 which abuts the stopper 46. The other components are the same as those in the first embodiment, and therefore the same components are assigned the same reference numerals on the drawings, and descriptions thereof are omitted. In this embodiment, while increasing the degree of freedom of the hose 35 protruding from the stopper 46, the sharp bending of the hose 35 is suppressed, so that the effect described in the first embodiment can be more significant. •effect. -10- 508385 V. Description of the Invention (9) (Third Embodiment) In each of the above embodiments, although the example in which the valve 34 is integrated with the hose connecting body 33 is disclosed, it can also be used in the valve. In the 34 main body, a fluid passage 37 and a distribution fluid passage 51 are formed in the body, and the piping joint 36 is directly installed on the valve 34 corresponding to each distribution fluid passage 51, thereby omitting the hose connection body described above. 33. With this embodiment, the functions and effects obtained in the above embodiment can be further enhanced. [Effects of the Invention] Since the present invention is constituted as described above, the effects described below can be achieved. According to the invention described in any of claims 1 to 3 of the scope of patent application, a simple piping joint is formed, and the main body part can be piping in order to connect the hose to the main body. The degree of freedom of piping in the restricted area, and piping can be performed without excess load on the hose. As a result, the durability of the hose is improved, and the goal of reducing the number of assembly workers is achieved.
