  The main shaft 22 and the rocking shaft 24 extend in parallel in the left-right direction, and are rotatably supported by the loom frames 12 and the reinforcing structure 26. The main shaft 22 is positioned below the height position of the rocking shaft 24.

  The rod 28 is supported by a plurality of swords 29 attached to the locking shaft 24, and is rocked by the rocking shaft 24 being angularly rotated in synchronization with the rotation of the main shaft 22, thereby performing a striking motion. do. The rocking shaft 24, the rod 28 and the sword 29 constitute a hammering device together.

  The warp beam 30 is rotatably and detachably supported by both loom frames 12 so as to be located on the rear side of the loom 10. The cloth winding beam 32 is rotatably and detachably supported by both loom frames 12 so as to be positioned on the front side of the loom 10.

  The plurality of warps 34 are fed out in the form of a warp sheet from the warp beam 30 and passed through the plurality of back rollers 36 and the reeds and reeds 28 attached to the corresponding reed frame 38. Each saddle frame 38 is moved up and down in synchronization with the rotation of the main shaft 22 by the corresponding motion transmission device 40.

  The woven fabric 42 woven by the beating motion of the reed 28 reaches the cloth winding beam 32 via a breast beam 44, a plurality of press rolls 46 and a clothing roll 48. The breast beam 44, the plurality of press rolls 46, and the clothing roll 48 are supported so as to be rotatable with respect to the loom frames 12.

  The reinforcing structure 26 includes a base member 50 that extends between the loom frames 12 and 12 in the weaving width direction, and one or more (specifically, spaced between the loom frames 12 and 12 in the weaving width direction). Includes a plurality of auxiliary frames 52, and a support member 54 that is individually arranged with respect to the auxiliary frame 52 and supported by the auxiliary frame 52.

  The base member 50 is made of a metal flat plate member having an appropriate width dimension and thickness, and is arranged in a state in which the longitudinal direction is the weaving width direction and the width direction is the front-rear direction of the loom. The main shaft 22 and the rocking shaft 24 extend in the woven width direction. For this reason, the main shaft 22 and the locking shaft 24 extend below and above the base member 50 in the weaving width direction, respectively. When the material is a steel plate, the thickness is specifically 15 mm or more (preferably 19 mm or more) from the viewpoint of strength.

  Each auxiliary frame 52 has a base portion 56 extending in the front-rear direction below the base member 50 and the main shaft 22.

  Each auxiliary frame 52 is attached to the first stay 14 via a base member 50 at an extension 63 extending from the front upper portion of the base 56, and extends from the base 56 at the front lower portion, the rear upper portion, and the rear lower portion. Each extension is attached to a second, third and fourth stay 16, 18 and 20, respectively.

  The stays 14, 16, 18, and 20 are connected to the auxiliary frames 52 by a plurality of bolts 15, 17, 19, and 21, respectively. As shown in FIG. 5, the first stay 14 is further connected to the base member 50 by a plurality of screw members 23. Further, instead of connecting the first stay 14 and the base member 50 with a plurality of screws, a known fixing method such as welding may be used. Moreover, it is also possible to integrally form these by casting or the like.

  Attached to each auxiliary frame 52 is an intermediate receiving member 58 that receives the main shaft 22 so as to be rotatable in the weaving width direction. However, the intermediate receiving member 58 may be attached to the lower surface of the base member 50.

  In any of the above cases, the main shaft 22 is supported and stabilized by the auxiliary frame 52 at a plurality of positions spaced in the longitudinal direction thereof. Further, in the latter case, as compared to the former case, as in the case of the rocking shaft, it is possible to support the main shaft 22 by freely setting and arranging the arrangement location and number of the intermediate receiving members with respect to the main shaft 22 in the weaving width direction. it can.

  Each middle receiving member 58 includes a bearing 58a that receives the main shaft 22, a middle receiving metal 58b that receives the bearing, and a middle receiving metal cap 58c that supports the bearing on the middle receiving metal 58b. The intermediate receiving metal 58 b is attached to the base portion 56 of the auxiliary frame 52 with a plurality of bolts 51 and 53 and a bracket 55.

  Each support member 54 is attached to a position above the base portion 56 of the corresponding auxiliary frame 52 with a plurality of bolts 57 so that the support member 54 extends in the vertical direction, and a plate-like base member 50 is attached to the upper end portion of the plurality of support members 54. It is attached with bolts 59.

  The base member 50 is connected to and supported by the first stay 14 and the auxiliary frame 52 at a location in front of the main shaft 22 and the locking shaft 24.

  The base member 50 is connected to the auxiliary frame 52 via a support member 54 at a location behind the main shaft 22 and the locking shaft 24 and is supported horizontally. For this reason, the support member 54 acts as a mounting seat for the base member 50 to the auxiliary frame 52.

  As described above, when the base member 50 is supported at two positions on the front and rear with respect to the axes (axial centers) of the main shaft 22 and the rocking shaft 24, even if vibration is generated by the rotational movement of the shaft, the source of the vibration is generated. As a result of the vibrations of the shaft being suppressed by the front and rear structures, the vibrations of the loom are suppressed. Further, when the reaction caused by the striking motion by the scissors 28 is received by the surface of the plate-like base member 50, the structure for supporting the locking shaft 24 is strengthened.

  The base member 50 supports a plurality of bearing members 60 that receive the rocking shaft 24 in the middle of the weaving width direction at intervals in the weaving width direction. For this reason, the rocking shaft 24 is supported and stabilized by the base member 50 at a plurality of positions spaced in the longitudinal direction thereof.

  Each bearing member 60 includes a bearing 60a that receives the locking shaft 24, an intermediate receiving metal 60b that receives the bearing, and an intermediate receiving metal cap 60c that supports the bearing on the intermediate receiving metal 60b. The intermediate receiving metal 60 b is attached to the upper surface of the base member 50 with a plurality of bolts 61.

  As shown in FIG. 5, the base member 50, the auxiliary frame 52, and the support member 54 may be arranged between the auxiliary frames 52 in the weaving width direction so as to be positioned at a plurality of positions relative to the plurality of bearing members 60. However, as shown in FIG. 6, the bearing members 60 may be disposed between the bearing members 60.

  The hold cover 62 is formed, for example, by a plate-like member having a thickness of several millimeters so as to extend in the woven width direction, and is attached to the base member 50 by an auxiliary member 64 that is band-shaped and bent into an L shape. The heald cover 62 is attached between the base member 50 and the support member 54 with a plurality of gap members 66 (see FIG. 9) sandwiched between the lower end surface of the base member 50 and is liquid-tight with respect to the support member 54. Attached. The auxiliary member 64 is disposed on the base member 50 with an interval in the weaving width direction to support the heald cover 62, and a plurality of gap members 66 are provided corresponding to the support member 54, and the gap member 66, a weft insertion jet water passage is formed in the gap between the base member 50 and the heald cover 62. The gap necessary for passing the jet water is several mm to several tens of mm, and such a gap is set by the thickness of the gap member. Further, it is not always necessary to place the gap member at the connecting position between the support member and the base member as in the illustrated example. The gap may be provided by being bent by the flexibility of the heald cover 62 at a portion. Alternatively, it may be considered that the heald cover 62 has a shape in which a gap is generated between the heald cover 62 and the base member 50. Further, at least a portion of the heald cover 62 connected to the base member 50 and the support member 54 is configured by a plate-like member having a sufficient thickness (for example, about several tens of millimeters) to have the same strength as the base member 50. , Function as a substantial striking reinforcement structure. Further, the gap can be formed by disposing the gap member 66 between the heald cover 62 and the base member 50.

  The hold cover 62 extends in the front-rear direction in a space surrounded by the base member 50, the base 56 of the auxiliary frame 52, and the support member 54. For this reason, the heald cover 62 forms a water droplet guide portion that prevents the wetting water for weft insertion from splashing on members disposed below the base member 50 such as the main shaft 22 and the support member 54. The heald cover 62 constituting the water droplet guide portion is formed so as to incline downward as it advances to the front side, and is provided so as to guide the water droplets accumulated in the water droplet guide portion forward, and its front end is led to a drainage tub described later. It has been.

  The heald cover 62 is also sandwiched between the base member 50 and the support member 54 and reaches the rear outside of the space. For this reason, the mounting structure of the heald cover 62 is simplified.

  The heald cover 62 further extends in the vertical direction behind the locking shaft 24. For this reason, the heald cover 62 is a water-blocking structure that prevents the wetting water for weft insertion from splashing to the members disposed below and behind the base member 50, that is, the lower portions of the support member 54 and the collar frame 38. A water guide portion as a portion is formed in cooperation with the first stay 14 and the base member 50. A space surrounded by such a water-impervious structure as a water guide is open upward.

  The drainage basin 68 that discharges the water guided by the water guiding portion extends in the weaving width direction in the space surrounded by the base member 50, the base portion 56 of the auxiliary frame 52, and the support member 54. And it arrange | positions so that it may incline in the weaving width direction. The drainage basin 68 is supported by the base member 50 via a member (not shown).

  In the water jet loom 10 described above, the plurality of bearing members 60 that rotatably receive the rocking shaft 24 that is the main vibration source of the loom are received by the base member 50 extending in the weaving width direction and the auxiliary frame 54 described below. It is done. Since the base member 50 extends between the loom frames 12 and 12 in the weaving width direction, the plurality of bearing members 60 that receive the locking shaft 24 are left and right on the base member 50 depending on the location and position of the auxiliary frame 54. Without being done, a suitable position and a suitable number can be arranged.

  On the other hand, the one or more auxiliary frames 54 disposed between the loom frames connect the plurality of stays including the first stay 14 and including at least one of the second to fourth stays 16, 18, and 20. Therefore, it constitutes a strong structure of the loom, and the base member 50 is supported by the first stay 14 and the auxiliary frame 54 on the front side and the rear side of the rocking shaft 24 that is the vibration source of the loom, respectively. As a result, the base member 50 is firmly supported by the first stay 14 and the auxiliary frame 54.

  Furthermore, since one or more auxiliary frames 54 that support the base member 50 are disposed in consideration of various devices such as a warp opening device disposed between the loom frames 12 and 12, these various types of the auxiliary frame 54 are more various than conventional ones. The structure for receiving the locking shaft 24 in the middle can be strengthened while ensuring the workability of the operator regarding the apparatus. As a result, the vibration of the loom caused by the vibration due to the hammering motion is reduced, and the weaving step caused by the vibration caused by the reaction during the hammering can be eliminated.

  In the above-described embodiment, since the base member 50 is further connected to the extension portion 63 of the auxiliary frame 54, the base member 50 is supported more firmly.

  In the water jet loom 10 described above, the weft insertion water sprayed from the weft insertion nozzle is a water droplet guide portion formed by the water shielding structure constituted by the first stay 14 and the base member 50 and the heald cover 62. Then, the water is collected in the water guide, and is led to the drain 68 and drained. By such a water droplet guide, the wetting cover 62 can prevent the wetting water for wetting into the main shaft 22 and the auxiliary frame 52 from being scattered. As a result, corrosion and contamination of those members are reduced, and those members are long-lived.

  Further, the first stay 14 and the base member 52 constituting a part of the water-blocking structure prevent the wetting jet water from splashing on the cloth winding roll 32 and the clothes winding roll 48. As a result, the woven fabric from which moisture has been removed by the dewatering cylinder disposed in the cloth winding path is prevented from getting wet again, and the number of parts for the water-blocking structure is reduced.

  In the water jet loom 10 described above, the reaction caused by the hammering motion is received by the auxiliary frame through the surface of the plate-like base member 50, the first stay provided in the front-rear direction, and the mounting seat of the support member. Thereby, the reaction is received by the surface of the mounting seat, and the structure for supporting the locking shaft 24 is further strengthened.

  As shown in FIG. 7, the base member 50 uses the weft insertion water collected by the water guide portion formed by the first stay 14, the base member 50, and the heald cover 62, to the base member 50 and the auxiliary frame 52. You may have the some notch 70 made to flow down to the space enclosed by the base 56 and the supporting member 54. FIG. In such a case, the water droplet guide portion may be extended so that the water that flows down from the cutout portion 70 is guided to the drainage basin 68 by the heald cover 62.

  Further, instead of forming the base member 50 with a single member, as shown in FIG. 8, a plurality of divided base members 72 may be configured. In this case, a gap 70 between the adjacent base members 72 may be used as the drainage notch 70, and the base member 50 does not necessarily extend over the entire width in the weaving width method, and the bearing member, the first stay, and the support member It suffices if it extends over the section of the mounting position. In the case of a configuration in which the base member 50 is partially extended as shown in FIG. 8, one place is provided at the central portion in the width direction with respect to the base member 50 with respect to the place where the support member 54 is arranged, that is, the auxiliary frame. Either two are provided near both ends in the width direction, or a plurality of them are arranged at intervals in the width direction. By providing the cutout portion 70 in this way, drainage can be performed smoothly, and the weight and cost of the loom can be reduced by the amount of the cutout of the base member 50. Furthermore, it is conceivable to provide a large number of through holes instead of providing the notches 70.

  As shown in FIG. 9, the support member 54 may be formed integrally with the auxiliary frame 52. On the contrary, the support member 54 may be formed integrally with the base member 50.

  As shown in FIG. 10, the locking shaft 24 may be disposed below the base member 50. Alternatively, the first stay 14 may be connected to the extension 63 of the auxiliary frame 52 and the base member 50 may be connected to the upper side of the first stay 14. In such a case, the base member 50 is formed with a not-shown notch for allowing the sword 29 to pass through, and the base member 50 can be beaten by a hook attached to an extension extending from the sword sword 29 to the upper side of the base member 50. it can.

  As shown in FIG. 11, the extension 63 on the front upper side of the auxiliary frame 52 is disposed at the position of the support member 54 in FIG. 9, and the support member 54 is formed at the position of the extension 63 of the auxiliary frame 52 in FIG. 9. The base member 50 may be connected to the first stay 14 and the auxiliary frame 52. Further, with respect to FIG. 11, a form in which the support member 54 is omitted, that is, a form in which the base member 50 is connected to and supported by the first stay 14 and the extension part 63 of the auxiliary frame 52 is also conceivable.

  As shown in FIGS. 12 and 13, a member bent into an L shape may be used as the base member 50. In this case, the auxiliary portion 50b bent in an L shape from the horizontally extending plate-like main portion 50a is positioned on the first stay 14 side on the rear surface of the first stay 14 as shown in FIG. They may be connected, or may be positioned on the support member 54 and connected to the front surface of the support member 54 as shown in FIG.

  As shown in FIG. 13, an L-shaped bent member may be used as the support member 54, and the support member 54 may be mounted on the base of the auxiliary frame such that the longitudinal direction thereof is the vertical direction.

  When a member bent in an L shape is used as the base member 50, the shape of the support member 54 is raised from the base 56 of the auxiliary frame 52 and the upper part thereof is bent forward as shown in FIG. The auxiliary portion 50b of the base member 50 may be connected to the front end of the support member 54.

  As shown in FIG. 15, the shape of the support member 54 is raised from the base portion 56 of the auxiliary frame 52 and the upper portion is bent forward, and the base member 50 extends in the woven width direction and the vertical direction. The upper end portion of the base member 50 may be connected to the rear surface of the first stay 14, and the lower end portion of the base member 50 may be connected to the front end of the support member 54.

  As described above, the shapes and structures of the base member 50, the auxiliary frame 52, the support member 54, and the like can be changed as appropriate.

  In the above embodiment, the extension 63 of the auxiliary frame 54 is connected to the first stay 14 via the base member 50, but directly connected to the first stay 14 without this. You may make it do. In the above embodiment, the auxiliary frame 54 is connected to all of the first to fourth stays 14, 16, 18, and 20, but the first stay to the fourth stays 14, 16 are shown. , 18 and 20 can be a plurality of stays including at least two of them. Specifically, the auxiliary frame 54 is configured to connect the first stay 14 and one of the second stay 16, the third stay 18, and the fourth stay 20, the first stay 14, A form in which two of the second stay 16, the third stay 18 and the fourth stay 20 are connected, or two of the second stay 16, the third stay 18 and the fourth stay 20 are connected.
