no. 1 Embodiment approach

[0036] Below, according to Figure 1 ~ Figure 2 The first embodiment of the present invention will be described.

[0037] Such as figure 1 As shown, the nozzles for weft insertion of the loom include a main nozzle 13 and auxiliary nozzles 14, 15, and 16. The main nozzle 13 includes a first nozzle 13a for weft insertion and a second nozzle 13b for weft insertion, which are respectively arranged in series. In addition, the auxiliary nozzles 14, 15, and 16 are formed of a plurality of (four in this case) nozzle groups, and are arranged on the sley 17 in the weft insertion direction.

[0038] On the side of the main nozzle 13, a thread supply unit 11 for supplying the weft yarn Y and a weft thread length-measuring storage device 12 for storing the supplied weft thread Y to a predetermined length are arranged.

[0039] In the air piping 18 from the side of the air supply source 30 to the first weft insertion nozzle 13a and the second weft insertion nozzle 13b, they are sequentia...

no. 2 Embodiment approach

[0062] Next, according to image 3 A second embodiment of the present invention will be described.

[0063] In this embodiment, the method of heat exchange in the first embodiment is changed.

[0064] Therefore, here, for the convenience of description, part of the reference numerals used in the previous description are used in common, description of the common configuration is omitted, and only the changed part will be described.

[0065] Such as image 3 As shown, in this embodiment, the opening drive motor 32 which is the heat generating source of the loom and the air in the air container 26 are thermally connected via the heat pump 40 . The heat pump 40 includes a heat sink 41 that exchanges heat with a heat generating source and takes away heat from the heat generating source, and transfers the taken away heat to the supply air in the air container 26 to exchange heat with the supply air. The heat radiation unit 42 uses a fluid as a heat exchange medium that circulates...

no. 3 Embodiment approach

[0074] Next, according to Figure 4 A third embodiment of the present invention will be described.

[0075] In this embodiment, the number of heat exchange parts of the first embodiment is increased.

[0076] Therefore, here, for the convenience of description, part of the reference numerals used in the previous description are used in common, and the description of the common configuration is omitted, and only the changed part will be described.

[0077] Such as Figure 4 As shown, in this embodiment, a part of the air pipe 18 from the air supply source 30 to the heat exchange unit 29 is branched to form an air pipe 51 , and another heat exchange unit 50 is provided in the air pipe 51 . Let the branch point of the air pipe 51 be S1, and the confluence point be S2.

[0078] In the heat exchange unit 29 , heat is exchanged between the opening drive motor 32 and the supply air, and the heat generated by the opening drive motor 32 is transferred to the supply air side to cool ...

Abstract

The invention provides a cooling device of air-jet loom to cool the heat source and keep stable filling operation performance. The air-jet loom comprises regulators (22, 27), air containers (21, 26),interrupter valves (19, 20, 23, 24, 25), which are orderly located from air supply source (30) to the air tubings (18) besides the filling operation nozzle. In the air-jet loom, in the tubing (18a) onthe higher position than the interrupter valves (19, 20, 23, 24, 25), heat exchange is process between the air in the tubing (18a) and the driven motor (32) as the heat source of function unit of theair-jet loom.

Description

technical field [0001] The present invention relates to a device for cooling a heat generating source of an air-jet loom by means of supply air for weft insertion. Background technique [0002] In the prior art disclosed in Patent Document 1, there is disclosed a cooling device in an air-jet loom, in which a stepping motor 24 as a rotary output device is arranged adjacent to the tandem nozzle 13 for weft insertion, and has a stepping motor 24 in a hexahedral shape. The side wall surface 243 of the body 242 of the motor 24 is in surface contact with the side wall surface 154 of the nozzle body 15 of the serial nozzle 13 . The movable body 26 is fixedly attached to the rotor shaft 241 of the stepping motor 24, and the path of the weft Y is changed from a linear first path to a curved second path by rotating the movable body 26. At the end of the weft insertion, the weft yarn Y shifts to the second path of the curved shape, thereby receiving a braking action to slow down the w...
