The present invention relates to a water jet loom that wefts into the jet stream, and to a technique for efficiently removing water from a woven fabric that is wet with the wefts.

In a water jet loom, the weft is inserted into the inclined opening when the weft is inserted, but the jet stream sprayed at that time drops into water droplets and infiltrates the surface of the woven fabric, the yarn of the woven fabric, and the voids of the yarn. (Iii) As a technique of removing water droplets from a wet woven fabric with such a water jet loom, a water removal tube having a suction port is disposed on a cloth winding path of the woven fabric, and the inside of the water removal tube is placed under a negative pressure to generate air flow to the suction port. Thereby, the apparatus which removes water from a woven fabric is known. (For example, refer patent document 1, 2.) However, since the airflow which permeates a woven fabric is generated, the moisture of a textile surface is a woven fabric in the vicinity of a suction opening. Although it passes through and removes this airflow, the degree of vacuum inside the water removal tube is significantly reduced. In addition, there is a problem that it is not possible to sufficiently remove the moisture permeated in the tissue of the woven fabric, that is, between the warp and the weft, and the water removal is insufficient.

On the other hand, as a technique of suppressing the airflow which permeates the said woven fabric and preventing the fall of the said vacuum degree, an impermeable sheet | seat or a cross-sectional arc shape so that the said water removal pipe | tube may cover the woven fabric which passes through a suction port from the woven fabric side. There is a technique of arranging the cover of the present invention (see Patent Documents 3 and 4, for example).

According to the techniques of Patent Documents 3 and 4, the degree of vacuum of the water removal tube can be increased as much as the airflow passing through the woven fabric can be suppressed, and the airflow passing through the crevice in the tissue of the woven fabric, that is, the warp and the weft, is slightly Although there is an increase, the water removal degree of the whole woven fabric does not improve as much as actually thought. Although it is not clear about the reason, according to the research of the present inventors, it is thought that it is as follows. When the airflow passes through the fiber, since the airflow must pass through the gap between the yarn and the yarn, this becomes a resistance to the airflow, which hinders the flow rate of the airflow. As a result, the area | region where the airflow of the intensity | strength which can suck water generate | occur | produces is limited to the narrow area | region around the suction opening. Moreover, compared with patent documents 1 and 2, the water droplet on the surface side of a woven fabric also makes the said gap of a woven fabric pass. In recent years, with the high-speed operation of water jet looms, the period of time when the woven fabric passes through the suction port tends to be shortened, and it is considered that such a short passage period does not sufficiently absorb moisture.

In order to achieve the desired degree of water removal of the woven fabric with such a device, the air flow is increased by increasing the degree of negative pressure. As a result, when the woven fabric passes through the suction pipe, the woven fabric is strongly attracted to the suction port, thereby damaging the woven fabric, or increasing the capacity of the suction blower, which is the negative pressure source, to increase power consumption and waste energy. there is a problem.

The present invention has been made in view of the above circumstances, and an object of the present invention relates to a technique for removing water from a woven fabric in a wet state according to weft weaving. It is to remove more efficiently.

Accordingly, the present invention provides a water removal tube disposed in a winding path of a woven fabric and arranged in contact with the woven fabric to a suction port provided in the woven width direction, and a sheet disposed to cover the suction port from the outside. The water removal apparatus of the water injection type loom which has the inside of the water removal pipe | tube, is made into the negative pressure state, and removes water by passing a woven fabric through the said suction port. In addition, the present invention is in at least one of the outer circumferential portion of the water removal tube or the sheet surface side in contact with the woven fabric of the sheet, which is in the section in which the water removal tube and the woven fabric are in contact with each other upstream or downstream of the suction port. A plurality of guide walls extending in a direction intersecting with the straight width direction are provided at intervals in the straight width direction over a section from one of them to at least the vicinity position in front of the suction port, and the guide walls are provided. The outer circumferential portion of the water removal pipe or the sheet is disposed such that the top of the guide wall is in contact with the woven fabric, and the guide wall defined in the adjacent guide wall is in a negative pressure state. This installation is assumed to be the first point.

Moreover, this invention is a sheet | seat provided in order to assist the removal of the water from the woven fabric in a water-jet loom, The sheet | seat is made to match the longitudinal direction in a straight width direction, and is formed in the straight width direction on a water removal pipe | tube. It is arranged to cover from the outside with respect to the suction port. Further, in the present invention, the sheet further has a sheet surface side in contact with the woven fabric and is located in a section where the water removal tube and the woven fabric are in contact with each other from upstream or downstream of the suction port to at least a position near the suction port. The second aspect of the present invention is that a plurality of guide walls extending in a direction intersecting the straight width direction are provided at intervals in the straight width direction.

According to the first and second points described above, at least one of the upstream side or the downstream side of the suction port is at least in front of the suction port on at least one of the sheet surface side contacting the outer circumferential portion of the water removal tube or the woven fabric of the sheet. A plurality of guide flow paths defined by adjacent guide walls are formed in the straight width direction over the section up to the position. On the other hand, in the water removal pipe, the inside thereof becomes a negative pressure state, whereby airflow from the guide flow path toward the suction port is generated. In addition, since the guide flow path is opened to the woven fabric side, water droplets and the like on the surface of the woven fabric are removed from the suction port through the guide flow path together with the generated airflow. Therefore, compared with the prior art, the amount of water removal from a woven fabric can be increased more. In addition, the negative pressure state here does not have a narrow meaning like a so-called vacuum state, but refers to an air pressure state lower than the atmospheric pressure (atmospheric pressure) of the surrounding environment.

Further, as in the first aspect described above, the guide wall is provided so that the guide flow path is in a negative pressure state, so that the guide wall is in a negative pressure state directly or indirectly by the airflow generated toward the suction port. . Thereby, the water which permeated into the tissue of the woven fabric other than the water droplets on the surface of the woven fabric is taken out into the guide flow path under the influence of negative pressure, and is transported to the suction port by the air flow to the suction port and removed. In other words, the guiding flow path that is open to the woven fabric side and is in the negative pressure state has the same function as the suction port for taking out the water droplets soaked from the woven fabric side. In addition, the suction passage for the woven fabric is substantially longer by the elongated guide passage as described above, and the negative pressure action period for the woven fabric can be made longer than before, so that the amount of water removed from the woven fabric can be further increased.

In addition, since the negative pressure in the guide flow passage has sufficient power to take out the water droplets and the water soaked from the woven fabric, the water can be removed in the desired state without increasing the vacuum degree in the water removal tube as in the prior art. Since it can remove, it becomes possible to suppress the capacity | capacitance of the suction blower which is a negative pressure generation source, and it is energy saving as much as power consumption can be suppressed.

In the first aspect, the guide wall can be provided on either or both of the outer circumferential portion of the water removal tube or the sheet surface side in contact with the woven fabric of the sheet.

According to the studies of the present inventors with respect to the guide wall in the two main points about the crossing angle [theta] 1 with respect to the extension direction of the suction port, it is preferable that it is 90 degrees or its vicinity value, and it is 90 degree about the vicinity value. For a range of ± tens of degrees.

Preferably, the guide wall is provided on the sheet, and the seat is provided in two sections which are continuously defined in the running direction of the woven fabric over the extension section of the guide wall, and the vicinity of the suction port. The starting point and the end point are determined so as to interpose, and the first section in which the starting point is determined at the position separated from the suction port, and the starting point of the first section are the end point, and further separated from the suction port. In the first section, the top section of the guide wall is in contact with the woven fabric, and in the second section, the top section is spaced apart from the woven fabric. good. As a result, in the second section, since the guide flow path is opened from the woven fabric, the amount of airflow flowing from the open space to the guide flow path in the first section is increased, and the guiding flow path is located near the position where the woven fabric and the sheet contact each other. Water droplets can be transported more smoothly to the suction port side. Moreover, according to the researches of the present inventors about the position to separate, it is preferable that it is tens of mm or more from the position of a suction opening.

More preferably, the said guide wall is provided in the said sheet | seat, The end point of the said 1st section is formed in the said sheet | seat so that the said suction port may be interposed between the said starting point, and the said 1st section A third section is formed continuously in the first section, with the end point of as the starting point and a position further separated from the suction port as the end point, and the sheet is the third section in which the guide wall does not exist. In the section, the sheet surface and the woven fabric may contact each other. By forming the third section in which such a sheet surface is in contact with the woven fabric, the air flow can be more concentrated on the first section and the second section side, so that the amount of water removed from the woven fabric is increased.

The sheet constituting such a water removing device is preferably composed of a plate-like sheet having flexibility and airtightness.

The hollow portion 12 of the suction pipe 13 is in a negative pressure state.

By the way, in the water spray loom, the water blocking structure is comprised for the purpose of preventing the scattering of the water droplets accompanying a weft, and as a part thereof, the shield plate which continues in the width direction in order to prevent the water droplets flying toward the front of the loom ( 24 and splash guard 27 are arranged.

The shield plate 24 includes a base portion 24A formed in a substantially rectangular tubular shape, an extension portion 25 extending from the base portion toward the back of the loom so that the cushion member 29 can be mounted, and will be described later. All of the mounting portions 28 functioning as mounting portions for the sheet 30 to be formed extend in the straight width direction. On the other hand, at the upper end of the holder cap 16 to be installed, an installation seat 18 extending substantially horizontally along the front and rear directions of the loom is formed to receive the lower end surface of the shield plate 24. Both ends of the shield plate 24 are fixed to the holder cap 16 by screwing the hexagon hole bolts 21 and 21 into the screw holes formed in the mounting positions 18 and 18. do.

The splash guard 27 is supported by the pipe 26 received through the member not shown in the frames 2 and 2 at the position of the rear end thereof. Thereby, the splash guard 27 is provided so that opening and closing of the front end part in the up-down direction centering on the pipe 26 is possible. In the closed state, the splash guard 27 receives a part of the water blocking structure of the weft-injected droplet by receiving the front end portion by the cushion member 29 provided in the extension portion 25. do.

As shown in FIG. 2, the sheet | seat 30 has the adhesive part 31A, 31B in which the both ends of the direction (up-down direction) orthogonal to a longitudinal direction are folded by predetermined length, and the folded end part is adhere | attached on a sheet surface. At the same time, the bag-shaped bag-shaped portions 32A and 32B are formed, which extend in the straight width direction and open at both ends in the straight width direction by the folded portion. In FIG. 4A, the water removal apparatus 10 seen from the direction shown by the square bracket English letter A in FIG. 2 is shown, and the right side view of the sheet | seat 30 is shown in FIG. . The mounting portion 28 of the shield plate 24 is provided with a sheet 30 extending in the straight width direction.

Bars 33 and 34 formed of a plate-like member extending in the straight width direction are respectively inserted into and held in the bag-shaped portions 32A and 32B. In order to install the sheet | seat 30, in the installation part 28 of the shield plate 24, the screw hole for screw fastening is provided in multiple numbers by the space | interval in the direct width direction, The bar 33 is the said bag shape In the state inserted into the part 32A, the loom 1 is screwed into each of the plurality of through holes formed corresponding to the plurality of screw holes formed in the mounting portion 28 by screwing. ) Is installed. As mentioned above, the sheet | seat 30 is arrange | positioned so that it may follow the woven fabric 7 which contacts the outer periphery of the suction pipe 13, and is turned down and guided. In addition, the bar 34 extending in the straight width direction functions as a weight for bringing the sheet 30, which is inclined as shown, into contact with the woven fabric 7 to be guided. 4A, although the suction port 11 of the suction pipe 13 extends further in both width directions from the position of the direct end of the woven fabric 7, the woven fabric 7 does not exist. A tape 42 is attached to each other to prevent the inflow of airflow from this region.

Here, the sheet 30 is made of a flexible resin material and is formed of a material having a thickness of about 0.2 mm to several mm, for example, a vinyl sheet having transparency, to the adhesive portions 31A and 31B described above. For example, a heated concave-convex mold (for example, one having a plurality of cross-sectional semicircular arc-shaped concave-convex portions formed in the width direction) is pressed by pressing a few seconds to several minutes to heat weld the sheets together.

On the other hand, as shown in FIG. 3, the sheet | seat 30 overlaps the one part section with respect to the contact section b with a woven fabric at the side of the sheet surface 35 which contacts the woven fabric of the bag-shaped part 32B. A plurality of guide walls 36, 36..., Extending in a direction intersecting the straight width direction are provided over the section c formed by determining the starting point w and the end point v. . 4A, 4B, and 5, the sheet surface 35 in contact with the woven fabric of the sheet 30 has a crossing angle θ1 with respect to the straight width direction, and the diameter P3. A plurality of semi-circular arc-shaped grooves 39 are provided for each distance P1 in the straight width direction. As a result, the guide wall 36 is formed by the convex portion 37 having the wall surfaces 39a and 39b of the adjacent grooves 39 and 39 and the top portion 35a of the seat surface 35 subsequent thereto. The grooves 39 and 39 are configured as the guide passages 38 and 38. In this case, the top part 35a of the seat surface 35 functions as the top part 36a of the guide wall 36, and is contacted with the woven fabric 7 as demonstrated later.

Moreover, with respect to the sheet | seat 30 comprised from a vinyl sheet, such grooves 39 and 39 are the width | variety direction of the convex part of the shape of the heated convex shape (for example, the semi-cylindrical shape of diameter P3), for example. Can be formed by pressing a plurality of the distances per distance P1, and pressing against the seat surface 35 for a few seconds to several minutes. However, the present invention is not limited thereto, and the guide wall 36 or the guide passage 38 may be configured by a known method.

In addition, it is also possible to provide the guide wall 36 below. For example, as shown in FIG. 6, the diameter P2 comprised from the same material as the sheet | seat 30 makes the convex member 37 of the cross section semicircle into the sheet | seat surface 35 of the sheet | seat 30 the distance P1. A plurality of sheets are arranged side by side and adhered to the sheet surface 35 at the same time. Thus, the convex members 37 and 37 which protrude from the seat surface 35 are comprised as guide walls 36 and 36, and the space which is formed between the adjacent convex members 37 and 37 is the guide flow path 38 and 38. May be configured as). In this case, the top portion 37a of the convex member 37 functions as the top portion 36a of the guide wall 36 and contacts the woven fabric 7 as described later.

Alternatively, the grooves 39 and 39 are formed in the seat surface 35 in combination with FIGS. 5 and 6, and the convex member 37 having a semi-cylindrical shape P2 having a diameter P2 is seated as shown in FIG. 7. Each to a corresponding top 35a of 35. In this way, the body protrudes from the bottom of the groove 39 by the convex member 37 adhered to the wall surfaces 39a and 39b of the adjacent grooves 39 and 39 and the top portion 35a subsequent thereto. It may be configured as the guide wall 36, and the space formed between the adjacent guide walls 36 and 36 may be configured as the guide flow paths 38 and 38. In this case, the top portion 37a of the convex member 37 functions as the top portion 36a of the guide wall 36 and contacts the woven fabric 7 as described later.

Here, although it is only a range which intersects with respect to the crossing angle (theta) 1 which the extension direction of the suction opening 11 and the guide wall 36 make, except 0 degrees or 180 degrees, when it thinks from a viewpoint which flows easily, Preferably it is preferable. The range is 40 ° to 140 °, more preferably 90 ° or its value (specifically, 70 ° to 110 °). Further, as setting parameters for the guide wall 36 for the guide flow path 38 to be in a negative pressure state, the height t1 of the guide wall, the thickness p2 of the guide wall, and the arrangement pitch p1 of the adjacent guide walls. , Extension length (c) and the like. According to empirical values, for example, the parameters t1, p2, and p1 are all in the range of 0.2 mm to 2.0 mm, and the extension section length c is 10 mm or more.

Thus, as shown in FIG. 3, the sheet | seat 30 provided with the guide walls 36 and 36 originates from the suction opening 11 at the position y upstream of the traveling route of the woven fabric 7. In a state in which it is arranged in contact with the woven fabric 7 over the section b having the position z on the downstream side as the end point from the suction port 11, and installed in the water removing apparatus 10, It is provided so as to contact the woven fabric 7 over the section c1 from the position u downstream to the position v from the starting point w of the section c. In other words, the top portion 36a of the guide wall 36 is formed of a woven fabric (i) for the section c used as the starting point w and the end point v at which the guide walls 36 and 36 are provided on the sheet 30. 7) the starting point u at which contact is initiated, the section c1 defined at the end point v, and the starting point w as the starting point, and the starting point u of the section c1 as the starting point. In the section c1 as the first section, the top portion 36a of the guide wall 36 is in contact with the woven fabric 7 in the section 30. In the section c2 as the section, the top portion 36a of the guide wall 36 is arranged to be spaced apart from the woven fabric 7. As a result, in the section c1, the guide passage 38 formed of the guide walls 36 and 36 that are adjacent to each other is opened to the woven fabric 7 that travels, and in the section c2, each other. The guide flow passage 38 composed of the adjacent guide walls 36 and 36 is open to the space between the woven fabric 7 and the sheet 30.

By the way, with the operation of the loom, the woven fabric 7 wetted by weft water flows between the suction pipe 13 and the seat 30. On the other hand, by the suction blower (not shown) operated by the operation of the loom, the hollow portion 12 of the suction pipe 13 is in a negative pressure state, and from within the tissue of the woven fabric 7 and from the guide passage 38. Airflow flowing toward the suction port 11 is generated. The plurality of guide passages 38 constituted by guide walls 36 and 36 which are adjacent to each other over the section c1 function as guide passages of the air flow to the suction port 11. Moreover, since it is open with respect to the woven fabric 7, the water droplets etc. of the surface of the woven fabric 7 pass through the guide flow paths 38 and 38 with the airflow which generate | occur | produced, and in the vicinity of the suction opening 11, It passes through the gap between the thread of the woven fabric 7 and the thread, reaches the suction port 11, and is discharged out of the system via the suction pipe 13.

Preferably, the guide walls 36 and 36 are provided so that the guide passages 38 and 38 are in a negative pressure state at least over the section c1 in contact with the woven fabric 7. As a result, in the guide flow paths 38 and 38, since the air flow generated toward the suction port 11 is directly or indirectly in a negative pressure state, the woven fabric other than water droplets on the surface of the woven fabric 7 The infiltrating water in the tissue of 7) is taken out into the guide flow paths 38 and 38 under the influence of negative pressure, and is conveyed to the suction port 11 by the airflow and removed. In other words, the guide flow paths 38 and 38, which are open to the woven fabric side and are in a negative pressure state as described above, have the same function as the suction port 11 for taking out the water droplets infiltrated from the woven fabric 7 side. In addition, the guide passages 38 and 38 extending as described above substantially increase the suction period for the woven fabric 7, and thus allow a longer period of negative pressure to the woven fabric than in the prior art. The amount of water removal can be further increased.

On the other hand, in the section c2, since the guide passages 38 and 38 are open to the space between the woven fabric 7 and the seat 30, the airflow flowing from the space into the guide passage 38 Is increased. As the airflow increases in this way, the water droplets of the woven fabric are more smoothly transported to the suction port 11 side, and are sucked into the suction port 11 through the gaps between the yarns in the tissue of the woven fabric 7.

In the example shown in FIG. 3, the section e as the third section in which the guide walls 36 and 36 do not exist is continuous to the section c1 with respect to the section b in which the sheet 30 is in contact. Is installed. More specifically, the seat 30 has the end point v of the section c1 in which the guide walls 36 and 36 are provided, while being located downstream from the suction port 11 beyond the suction port 11. In the downstream direction of the section (c1), this end point (v) is the starting point, and further away from the suction port 11, so that the outer circumference of the suction pipe 13 and the woven fabric 7 are separated from each other. A section e having a position to be the end point r is provided. As a result, the seat 30 is provided with a section e having the end point v of the section c1 as its starting point and a position r further separated from the suction port 11 as the end point. In this section e, the seat surface 35 and the woven fabric 7 and the woven fabric 7 and the outer circumferential surface of the suction pipe 13 are arranged to be in contact with each other.

The contact of the seat surface and the woven fabric and the contact of the woven fabric and the suction pipe in such a section (e) suppresses the flow of airflow from this section. For example, since the negative pressure of the suction port 11 moves more intensively by the section c1 and the section c2 on the upstream side than the form where the section e does not exist, the guide passage 38, 38) The amount of airflow in the vessel and the degree of negative pressure are increased to increase the amount of water removed from the woven fabric.

By the way, 1 experiment data when the said water removal apparatus is applied to our water spray loom is shown in FIG. The following data is the experimental result data which evaluated the water removal effect of the woven fabric 7 by changing the capability of the sheet | seat 30 and the suction blower several. In addition, the premise water jet loom is our water jet loom, and the product type of the loom is zw408, the body width designation is 340 cm, the inclination is polyester 75dtex / 24f twisted Z800T / m, the weft is polyester 84dtex36f It is twisted Z800T / m, and loom rotation speed is 450 rpm. In addition, a separator in which a so-called float was incorporated was used as a mechanism for draining the separated water.

In addition, the sheet | seat is made into the sheet | seat A and this invention as sheet | seat B for the conventional product (namely, the flat sheet surface without a guide wall) with respect to the sheet | seat as the material whose transparency is a vinyl sheet of thickness 1mm. In addition, while the slit width of the suction port 11 is about 5 mm, the height t1 of the guide wall and the thickness p2 of the guide wall are 0.5 mm in the setting parameters of the sheet 30 of the present invention, respectively. The arrangement pitch p1 of the adjacent guide wall is 1.5 mm, the section length c is 40 mm, and the crossing angle θ1 is 90 degrees. In addition, with respect to the suction blower, ones of 750w and 400w, which are extremely commonly used, were selectively installed. In the column at the degree of water removal of FIG. 8, the result of the fabric surface inspecting worker objectively evaluating the residual amount of water in the woven fabric 7 after passing through the suction pipe 13 is objectively evaluated in three stages. In the column of evaluation, the water removal degree, the quality of a fabric, and the power consumption of a suction blower were also considered, and the result evaluated by three steps is shown.

According to the result shown in FIG. 8, in sheet A, although the degree of water removal is inadequate with the suction blower which is extremely common, the water removal degree in any sheet blower satisfies the criteria in a woven fabric factory. . In addition, it shows that the water removal effect of the grade which satisfies the criterion of a woven fabric factory can be acquired even if the ability of a suction blower is smaller than about 400 watts compared with the sheet A which is conventional. In other words, even when the degree of negative pressure is not increased as in the related art, it is shown that an air flow of a force sufficient to remove water from the woven fabric 7 is generated in the guide passage, so that the capacity of the suction blower as the source of negative pressure can be suppressed. do. Therefore, the energy saving of the suction blower is further suppressed.

By the way, the said embodiment can be modified below. First, although the end point v is set so that the suction opening 11 may be interposed with respect to the starting point u about the section c in which the guide walls 36 and 36 are provided, it does not necessarily need to be, and the end point v ) May be set to the section of the suction port 11 or the vicinity thereof (the position x shown in FIG. 2) in front of the suction port 11. In addition, this position (x) should just be caused to generate airflow in the guide flow paths 38 and 38 according to the negative pressure in the hollow part 12, According to the researches of the present inventors, this position x is shown in FIG. As shown in 3, the position spaced apart in the direction away from the suction port 11 by several mm is the limit.

In the above example, the section c2 in which the guide walls 36 and 36 are separated from the woven fabric 7 or the section in which the guide walls 36 and 36 are not provided in the downstream side with respect to the section c1. Although (e) is provided, it is also possible to comprise so that it may not be provided depending on the kind of fabric and the ability of a suction blower. In other words, the guide walls 36 and 36 may be provided beyond the section b where the sheet surface 35 and the woven fabric 7 contact each other.

The cross-sectional shape of the guide wall (guide flow path) is not limited to the semicircular shape as shown in Figs. For example, it is good also as shapes other than cross-sectional square (triangle, square).

The guide wall 36 is formed so as to extend in a straight line along the axis of the crossing angle θ1 in FIG. 4, but goes in a curved direction as shown in FIG. 9, that is, in the advancing direction of the woven fabric. It is also possible to provide the guide wall 36 so that the crossing angle [theta] 1 changes according to the above. In addition, although FIG. 4 is an example in which the guide wall 36 is continuously formed over the section c, as shown in FIG. 10, a plurality of guide walls 36 are intermittently comprised with respect to the advancing direction of a woven fabric, It is also possible to provide a plurality of guide walls 36 and 36 with a space 40 therebetween. In addition, as shown in FIG. 11, you may provide so that the flow path of airflow may be suppressed by providing the bank 41 which inhibits the flow of airflow in the flow path of some adjacent guide flow paths. In other words, as long as the guide wall 36 extends in the direction of the crossing angle θ1, it is included in the present invention.

In addition, the guide walls 36 and 36 which are adjacent to each other do not have to be the same shape. For example, as shown in FIG. 12, the guide wall 36 arrange | positions the guide wall 36 of a different shape, In addition, it is also possible to provide so that the respective directional directions of the guide flow passages constituted by the guide walls adjacent to each other differ from the neighboring guide flow passages 38 and 38.

Second Embodiment

In the above embodiment, instead of providing the guide wall 36 on the seat 30 side, as shown in FIG. 13, the guide wall 36 may be provided on the outer circumferential portion of the suction pipe 13. In the example shown in FIG. 13, the suction opening 11 has the groove | channel 47 which has the crossing angle (theta) 1 with respect to the extension direction (ground direction) of the suction opening 11, and extends in a circumferential direction over the section c. It is formed over a section that includes, and is also an example of installing a plurality of such grooves 47 side by side in the straight width direction. In the case of this embodiment, as in the case of FIG. 6, the formed grooves 47 function as the guide passages 46 as they are, and the partition portions remaining between the adjacent grooves 47 and 47 are formed in the guide wall ( 45).

In this way, when the guide wall 45 is provided on the outer circumferential surface side of the water removal pipe, the guide passage 46 becomes a guide passage through which one end thereof is connected to the suction port. The guide flow path which is directly in a negative pressure state by the airflow and is open to the woven fabric side functions as the suction port. Therefore, the amount of water removal from the woven fabric 7 increases as the area of the suction section with respect to the woven fabric becomes substantially wider. In addition, about some setting examples and modification examples of the guide wall described in the part of the first embodiment, the same applies to the second embodiment of the present invention.

With respect to the above two embodiments, the following configurations are possible. In the above-mentioned embodiment, although the guide flow path comprised by the guide wall which adjoins mutually is shown the example arrange | positioned only in either one of the outer periphery of the suction pipe 13 at the seat 30 side, the guide wall in both of said guide walls is shown. The guide flow paths may be provided respectively.

In the above embodiment, the guide wall (guide flow path) is provided in any of the first and second embodiments so that the extension length of the section c on the upstream side of the suction port 11 is longer than on the downstream side. . However, on the contrary, the downstream side may be long. In addition, about the 1st Example, the sheet | seat 30 is provided downstream with respect to the suction port 11 by swapping the front and rear sections c2 and e about the section c1. In the section c2, the sheet surface 35 and the woven fabric 7 may be provided so as to be separated from the woven fabric 7 and in the section e provided upstream from the suction port.

When the guide wall (guide flow path) is formed on the sheet side as in the first embodiment described above, the cross-sectional shape of the suction pipe 13 is not limited to the cylindrical shape as in the above two embodiments. For example, by forming a concave portion or a convex portion with respect to the outer circumferential surface thereof, it is possible to apply to a water removing apparatus having a higher water removal efficiency from the outer circumferential surface side of the suction pipe 13 relative to the woven fabric 7. In this device, the sheet removing device of the first embodiment may be provided with the seat 30 of the first embodiment.

Furthermore, for the sheet 30 or suction pipe 13 constituting the guide wall (guide flow path), a plurality of types of different ones of the set parameters opened for the guide wall 36 are prepared. In addition, it is also possible to select and install appropriate ones corresponding to changes in fabric specifications.

The present invention is a so-called water spray loom that is placed on a jet jet of water and wefts through a weft yarn in an inclined opening when weft weaving. It is applicable to looms.
