  The present invention relates to a wetting device in a gluing machine that passes warp wetted with water between a pair of squeezing rollers and squeezes water from the warp by the squeezing action of the pair of squeezing rollers before gluing the warp. Is.

  The gluing process in which the warp is preliminarily wetted with water before gluing the warp increases the gluing effect and leads to a reduction in glue material. In general, it is effective to immerse the warp yarn in 80 ° C to 90 ° C hot water stored in a water storage tank and then dewater the warp yarn moistened with water to a predetermined moisture content before gluing the warp yarn. Is known to be.

  As a wetting device for wetting the warp, there are a water storage tank for storing water, an immersion roller immersed in the water in the storage tank, and a surface of the immersion roller above the water surface of the water in the storage tank. A configuration including a squeezing roller pressed against the peripheral surface of the immersion roller via a wound warp is common (see, for example, Patent Document 1). The warp is dipped in the water in the water tank and wetted.

However, since the warp is immersed in the water in the water storage tank, even if it is squeezed with a squeeze roller, it cannot be sufficiently dehydrated, and an appropriate moisture content (water content / yarn weight) may not be obtained. In the apparatus disclosed in Patent Document 2, water is sprayed from the nozzle on the upper surface side of the warp so that the warp is not immersed in the water in the water storage tank.

Thereby, the paste liquid N is supplied from the paste liquid supply source 14 to the paste liquid tank 11. Further, the controller C1 controls the on-off valve 15 to be closed when the level N1 of the paste N in the paste tank 11 reaches a predetermined height. Thereby, supply of the paste liquid N from the paste liquid supply source 14 is stopped. For this reason, the height of the liquid surface N1 of the paste liquid N in the paste liquid tank 11 is maintained in a certain range.

A paste liquid adjusting pump 18 is interposed in the middle of the paste liquid supply pipe 17. The paste liquid adjusting pump 18 pressure-feeds the paste liquid N in the paste liquid tank 11 into the paste liquid supply units 21 and 22 through the paste liquid supply pipe 17.

  A paste liquid discharge hole 24 for discharging the paste liquid N is formed through the peripheral walls of the paste liquid supply devices 21 and 22. The paste liquid discharge hole 24 communicates with the insides of the paste liquid supply devices 21 and 22, and the paste liquid N fed into the cylinders of the paste liquid supply devices 21 and 22 is connected to the outside from the paste liquid discharge hole 24. It is designed to be discharged.

  In addition, a pair of cylindrical squeezing rollers 31 and 32 are arranged directly below the glue liquid supplier 21 so as to be along the longitudinal direction (axial direction) of the glue liquid supplier 21. In addition, a pair of cylindrical squeezing rollers 33 and 34 are arranged directly below the glue liquid supplier 22 so as to be along the longitudinal direction (axial direction) of the glue liquid supplier 22. As shown in FIG. 1, the glue liquid discharge hole 24 is disposed at a position that falls within the range of the falling quarters S <b> 1 and S <b> 2 on the upper half side of the squeeze rollers 31 and 33 when viewed in the vertical direction. . That is, the glue liquid discharge hole 24 traces a quarter turn from the tops 312 and 332 of the squeezing rollers 31 and 33 to the rotation direction R1 of the squeezing rollers 31 and 33 when viewed in the vertical direction. It is arranged at a position that falls within the range (falling quarters S1, S2) up to K1, K2.

  The pair of squeezing rollers 31 and 32 and the pair of squeezing rollers 33 and 34 sandwich a plurality of warps T arranged in a sheet shape. That is, a large number of warps T arranged in a sheet shape are passed between a pair of cylindrical squeezing rollers 31 and 32 and between a pair of cylindrical squeezing rollers 33 and 34. Note that a large number of warps T arranged in a sheet form are sent from the wetting device 3. The squeezing rollers 31 and 33 rotate in the direction of the arrow R1 (counterclockwise direction), and the squeezing rollers 32 and 34 rotate in the direction of the arrow Q1 (clockwise direction). It has become.

  Further, the warp T takes a path that is a tangent to the peripheral surfaces 311 and 321 of the squeezing rollers 31 and 32 in the gripping portion H1 of the squeezing rollers 31 and 32 as a pair. Further, the warp T takes a path that is a tangent to the peripheral surfaces 331 and 341 of the squeezing rollers 33 and 34 at the gripping portion H2 of the paired squeezing rollers 33 and 34.

  A glue receiver 35 is disposed immediately below the pair of squeezing rollers 31 and 32 and the pair of squeezing rollers 33 and 34. The bottom wall 351 of the paste receiver 35 has a shape that is recessed downward. The bottom wall 351 is disposed at a position where it does not contact the squeeze rollers 32 and 34. A paste collecting pipe 36 is connected to the bottom of the bottom wall 351. The paste collecting pipe 36 is led to the paste tank 11 disposed below the paste receiver 35. The liquid surface N1 having a predetermined height at which the supply of the paste liquid N from the paste liquid supply source 14 is stopped is set below the paste liquid receiver 35.

Next, the wetting device 3 for moistening the warp T before gluing the warp T will be described.
The wetting device 3 includes a water tank 41 for temporarily storing water W. A water tank heating pipe 42 is disposed in the water tank 41, and steam at a predetermined temperature is supplied from the steam supply source 13 into the water tank heating pipe 42. The steam amount and steam temperature supplied from the steam supply source 13 into the water tank heating pipe 42 are such that the temperature of the paste N in the water tank 41 falls within a desired temperature range (for example, 90 ° C. to 95 ° C.). Adjusted to

  The water tank 41 is connected to a water supply source 44 for storing newly supplied water W, and the water supply source 44 supplies water to the water tank 41 when the water W in the water tank 41 falls below a certain amount. It comes to replenish. More specifically, the water supply source 44 includes a controller C2 that controls the opening / closing of the opening / closing valve 45, and the controller C2 uses a level sensor 46 that detects the height of the liquid level W1 of the water W in the water tank 41. The liquid level information is received, and the opening / closing of the on-off valve 45 is controlled based on the liquid level information. That is, the controller C2 performs control so that the on-off valve 45 is opened when the height of the liquid level W1 of the water W in the water tank 41 becomes a predetermined height or less. Thereby, water is supplied from the water supply source 44 to the water tank 41. Further, the controller C2 controls the on-off valve 45 to be closed when the height of the liquid level W1 of the water W in the water tank 41 reaches a predetermined height. Thereby, the supply of water from the water supply source 44 is stopped. For this reason, the height of the liquid surface W1 of the water W in the water tank 41 is kept in a certain range.

  A water supply pipe 47 is connected to the bottom wall 411 of the water tank 41. A cylindrical (pipe-shaped) water supply device 51 is connected to the end of the water supply pipe 47. A water amount adjusting pump 48 is interposed in the middle of the water supply pipe 47. The water amount adjusting pump 48 is configured to pump the water W in the water tank 41 into the cylinder of the water supply device 51 through the water supply pipe 47.

  And as shown in FIG.2 and FIG.3, the water discharge hole 54 is penetrated and formed in the surrounding wall of the said water supply device 51. FIG. The water discharge hole 54 communicates with the inside of the cylinder of the water supply device 51, and the water W pumped into the cylinder of the water supply device 51 is discharged from the water discharge hole 54 to the outside. . The water W is pumped from both ends in the longitudinal direction of the water supply device 51 (both ends in the left-right direction in FIG. 3).

  A pair of cylindrical squeezing rollers 61 and 62 are disposed directly below the water supply device 51 so as to extend along the longitudinal direction (axial direction) of the water supply device 51. As shown in FIGS. 1 and 2A, the water discharge hole 54 is disposed at a position that falls within the range of the descending quarter circumference S3 on the upper half circumference side of the squeeze roller 61 when viewed in the vertical direction. Yes. That is, when viewed in the vertical direction, the water discharge hole 54 extends from the top 612 of the squeezing roller 61 to the boundary K3 between the upper half circumference and the lower half circumference by following a quarter turn in the rotation direction R3 of the squeezing roller 61 (four descending points). It is arranged at a position entering the half circumference S3).

  The pair of squeezing rollers 61 and 62 sandwich a large number of warps T arranged in a sheet shape. That is, a large number of warps T arranged in a sheet shape are passed between a pair of cylindrical squeezing rollers 61 and 62. The squeezing roller 61 rotates in the direction of the arrow R3 (counterclockwise direction). The squeezing roller 62 rotates in the direction of the arrow Q3 (clockwise direction). Further, the warp T takes a path that is a tangent to the peripheral surfaces 611 and 621 of the squeezing rollers 61 and 62 at the gripping portion H3 of the paired squeezing rollers 61 and 62. The warp T passed between the squeezing rollers 61 and 62 is sent to the gluing device 2.

  Further, a water receiver 65 is disposed immediately below the pair of squeezing rollers 61 and 62. The bottom wall 651 of the water receiver 65 has a concave shape. The bottom wall 651 is disposed at a position where it does not contact the squeezing roller 62. A water recovery pipe 66 is connected to the lowermost part of the bottom wall 651. The water recovery pipe 66 is led to a water tank 41 disposed below the water receiver 65. The liquid surface having a predetermined height at which water supply from the water supply source 44 is stopped is set below the water receiver 65.

Next, the flow from when water is supplied to the warp T to when the paste N is supplied to the warp T and the warp T is wound will be described.
When the water amount adjusting pump 48 is operated while the squeezing rollers 61 and 62 are rotating, the water W in the water tank 41 is pumped into the cylinder of the water supplier 51 by the operation of the water amount adjusting pump 48. The flow rate of the water supplied to the water supply device 51 can be easily adjusted by adjusting the rotational speed of the water amount adjusting pump 48, for example.

  The water pumped into the cylinder of the water supply device 51 as the water supply means is discharged from the water discharge hole 54. The water discharged from the water discharge holes 54 is supplied onto the descending quarter circumference S3 of the squeezing roller 61. The water W travels down the half-circumference S6 (shown in FIG. 1) of the squeezing roller 61 and adheres to the warp T in the vicinity of the grip portion H3. A part of the water adhering to the warp T near the grip portion H3 is squeezed from the warp T by the squeezing action of the squeezing rollers 61 and 62.

  The water squeezed from the warp T travels down the ascending half circumference U3 of the lower squeeze roller 62 (range from the gripping portion H3 to the lowest level 622 of the peripheral surface 621 of the squeeze roller 62 as shown in FIG. 1). A portion of the water that travels down the rising half circumference U3 of the squeezing roller 62 moves to the gripping portion H3 and adheres to the warp T as the squeezing roller 62 rotates. Part of the water that travels down the rising half circumference U3 of the squeezing roller 62 falls on the inner wall surface 652 of the bottom wall 651 of the water receiver 65. The water dropped on the inner wall surface 652 of the bottom wall 651 of the water receiver 65 does not adhere to the squeeze roller 62. That is, the squeezing roller 62 does not pick up the water that has dropped onto the inner wall surface 652 of the bottom wall 651 of the water receiver 65. An inner wall surface 652 of the bottom wall 651 provided in the water receiver 65 so as not to contact the lower squeezing roller 62 is a receiving portion that receives water falling from the squeezing rollers 61 and 62. The inner wall surface 652 as a receiving part is always in a position where it does not contact the squeezing roller 62 during operation, that is, under any operating condition. That is, the inner wall surface 652 is always in a position where it does not contact the squeezing roller 32 regardless of the operation speed of the gluing device 2 (that is, the peripheral speed of the squeezing rollers 31 and 32). The water dropped into the water receiver 65 is recovered into the water tank 41 via the water recovery pipe 66.

  The water W collected in the water tank 41 is sent again to the water supply 51 by the operation of the water amount adjusting pump 48. The water tank 41, the water supply pipe 47, and the water amount adjusting pump 48 constitute a reflux unit that sends the water received by the water receiver 65 to the water supplier 51. The warp yarn T that has passed between the squeezing rollers 61 and 62 is then sent to the gluing device 2.

  When the paste liquid adjusting pump 18 is operated while the squeezing rollers 31 to 34 are rotating, the paste liquid N in the paste liquid tank 11 is moved by the operation of the paste liquid adjusting pump 18 to the cylinders of the paste liquid supply units 21 and 22. It is pumped in. The flow rate of the paste liquid supplied to the paste liquid supply devices 21 and 22 can be easily adjusted by adjusting the rotational speed of the paste liquid adjusting pump 18, for example.

  The paste liquid fed into the cylinders of the paste liquid supply devices 21 and 22 as the paste liquid supply means is discharged from the paste liquid discharge hole 24. The paste liquid N discharged from the paste liquid discharge hole 24 is supplied onto the quadrants S1 and S2 of the squeezing rollers 31 and 33. The glue liquid N travels down the halves S4 and S5 (shown in FIG. 1) of the squeezing rollers 31 and 33 and adheres to the warp T sent from the wetting device 3 near the gripping portions H1 and H2. Part of the glue liquid adhering to the warp T near the gripping portion H1 is squeezed out from the warp T by the squeezing action of the squeeze rollers 31 and 32. Part of the glue liquid adhering to the warp T near the gripping portion H2 is squeezed out from the warp T by the squeezing action of the squeeze rollers 33 and 34.

  The glue solution squeezed from the warp T is raised by the lower squeezes U1 and U2 of the lower squeeze rollers 32 and 34 (as shown in FIG. 1, from the gripping portions H1 and H2 to the peripheral surfaces 321 and 341 of the squeeze rollers 32 and 34 Go down the lowest range 322, 342). A part of the glue liquid that travels down the rising half circumferences U1 and U2 of the squeezing rollers 32 and 34 moves to the gripping portions H1 and H2 and adheres to the warp T as the squeezing rollers 32 and 34 rotate. A part of the paste liquid that travels down the rising half circumferences U 1 and U 2 of the squeezing rollers 32 and 34 falls onto the inner wall surface 352 of the bottom wall 351 of the paste liquid receiver 35. The paste liquid dropped into the paste liquid receiver 35 is recovered into the paste liquid tank 11 via the paste liquid recovery pipe 36.

  The paste liquid N collected in the paste liquid tank 11 is sent again to the paste liquid feeders 21 and 22 by the operation of the pump 18. Further, the warp T passing between the squeezing rollers 33 and 34 is dried by a drying device (not shown) and then taken up by a winding unit (not shown).

  And the water discharge hole 54 provided in the water supply device 51 of this embodiment is formed in the shape which can supply the water W with respect to the warp T uniformly. Hereinafter, the water discharge hole 54 will be described in detail.

  As shown in FIG. 3, the water discharge holes 54 penetratingly formed in the water supply device 51 extend along the longitudinal direction (axial direction) of the water supply device 51, that is, along the longitudinal direction (axial direction) of the squeeze rollers 61 and 62. Formed. In other words, the water discharge hole 54 is formed in a slit shape having a long side in the longitudinal direction (axial direction) of the water supply device 51. Further, the water discharge holes 54 formed through the water supply device 51 are formed so that the width in the circumferential direction of the water supply device 51 is the same (uniform). That is, the water discharge hole 54 has a slit shape (rectangular shape) in plan view along the longitudinal direction of the water supply device 51. The water supply holes 51 are each provided with a plurality of rows (in this embodiment, two rows) of water discharge holes 54.

  Further, the water discharge hole 54 is provided with a joint 55 that connects the width of the water discharge hole 54 (the width in the circumferential direction of the water supply device 51) at every predetermined interval (25 mm in this embodiment). By the joint 55, the width (circumferential width) of the water discharge hole 54 is maintained at a constant interval. That is, when the water discharge hole 54 is formed by a single slit continuous in the longitudinal direction, it is difficult to keep the slit width uniform due to the physical properties of the material of the water supply device 51. However, according to this embodiment, when the joint 55 forms the water discharge hole 54, the width of the water discharge hole 54 is prevented from being deformed by an internal stress generated in the water supply device 51. In addition, in the longitudinal direction of the water supply device 51, the length of the joint 55 is formed to be extremely shorter than the installation interval of the joint 55 (25 mm in the present embodiment), and is 2 mm in the present embodiment. ing.

  Further, as shown in FIG. 3, the joints 55 are provided so as to be alternately arranged with joints 55 of the water discharge holes 54 in adjacent rows. That is, in the circumferential direction of the water supply device 51, when the joint 55 is arranged in the water discharge hole 54 in one row, the joint 55 is not arranged in the water discharge hole 54 in the other row. It has become. In other words, the joint 55 is provided in each water discharge hole 54 so that at least one location where the water W is discharged is arranged in the circumferential direction of the water supply device 51. Thereby, in the circumferential direction of the water supply device 51, the joints 55 from which water W is not discharged are not arranged at the same position in the two rows of water discharge holes 54. There is no place where W is not discharged.

  The water supply 51 in which such a water discharge hole 54 is formed is arranged so that the water discharge holes 54 are parallel to the squeezing rollers 61 and 62, respectively. That is, the water discharge holes 54 are arranged such that the longitudinal direction thereof is perpendicular to the traveling direction of the warp T. The length of the water discharge hole 54 in the longitudinal direction is equal to or greater than the width of the sheet composed of an array of a plurality of warps T.

Next, the operation of the water discharge hole 54 formed in such a shape will be described.
When the water W is pumped into the cylinder of the water supply device 51, the water discharge hole 54 discharges the water W to the outside. At this time, the shape of the water discharge holes 54 is formed so as to extend along the axial direction of the water supply device 51, and the width is always uniform by the joints 55. The water W to be discharged is discharged in the form of a film having a uniform thickness. Further, the joints 55 are alternately arranged in the two rows of the water discharge holes 54, and the length of the joints 55 is formed to be extremely shorter than the length of the water discharge holes 54 in the longitudinal direction. Therefore, the water W discharged from each water supply device 51 (two rows of water discharge holes 54) is discharged substantially uniformly in the longitudinal direction. For this reason, it is possible to prevent unevenness in the amount of water supplied to the warp T via the squeezing rollers 61 and 62. For this reason, it is possible to easily bring an appropriate moisture content to all the warps T.

As described above in detail, the present embodiment has the following effects.
(1) Since the water discharge holes 54 for discharging the water W are formed to extend along the axial direction of the water supply device 51, the water W discharged from the water discharge holes 54 is supplied to the water supply device 51 (and the throttle). It becomes uniform along the axial direction of the rollers 61, 62). For this reason, the water W supplied to the warp T becomes uniform. Further, since the water W is supplied from the water supply device 51 to the peripheral surface 611 of the upper squeezing roller 61 that sandwiches the warp T, it is easy to supply an appropriate amount of water W to the warp T. Accordingly, it is possible to easily supply an appropriate amount of water W uniformly to all the warps T. For this reason, it is possible to easily bring an appropriate moisture content to all the warps T.

  (2) The water discharge hole 54 is provided with a joint 55 for maintaining the width of the water discharge hole 54 at a constant interval. For this reason, it can prevent that the width | variety of the water discharge hole 54 deform | transforms (expands or narrows) by the internal stress etc. which arise in the water supply device 51. Accordingly, the water discharge holes 54 can always supply the water W uniformly in the longitudinal direction of the water discharge holes 54.

  (3) The joints 55 are provided so as to be alternately arranged with the joints 55 of the water discharge holes 54 in adjacent rows. For this reason, in the circumferential direction of the water supply device 51, the seams 55 from which water W is not discharged are not arranged at the same position in the two rows of water discharge holes 54. There is no place where W is not discharged. Therefore, the water W can be discharged almost uniformly in the longitudinal direction from each water supply device 51 (two rows of water discharge holes 54).

  (4) The falling quarter S3 is a range that falls toward the warp T along with the rotation of the squeezing roller 61, and the water W discharged from the water supply device 51 falls toward the warp T. Get down and land on S3. The water W that has landed on the descending quarter-circumference S3 surely reaches the warp T near the grip portion H3. The descending quarter circumference S3 is a water supply location suitable for guiding an appropriate amount of water discharged from the water supply device 51 onto the warp T.

  (5) The warp T takes a path that is a tangent to the peripheral surfaces 611 and 621 of the pair of squeezing rollers 61 and 62 in the grip portion H3. That is, the warp T passes through the grip portion H3 without being bent. The configuration in which the warp T is allowed to pass through without bending the warp T can reduce the number of bent portions of the warp T and reduce damage to the warp T due to the bend.

  (6) The water W that has fallen into the water receiver 65 moves to the water tank 41 without collecting in the water receiver 65. The water receiver 65 that does not store the water W can have a simple configuration as compared with a conventional blowing tank. Moreover, the water receiver 65 which does not store the water W can be made compact compared with the conventional water tank.

In addition, the said embodiment can be embodied in another embodiment (another example) as follows.
In the above embodiment, the water receiver 65 is disposed directly below the squeezing rollers 61 and 62. However, the water receiver 65 may be omitted and the water tank 41 may be disposed directly below the squeezing rollers 61 and 62. In this case, the liquid level of a predetermined height at which water supply from the water supply source 44 is stopped is set further below the lower squeeze roller 62 so that the squeeze roller 62 does not pick up the water W. There is a need to. In this case, the liquid level W1 is a receiving part.

  In the above embodiment, water W is supplied to the peripheral surface 611 of the squeezing roller 61 above the warp T introduced between the squeezing rollers 61, but water is supplied to the upper surface of the warp T upstream of the squeezing roller 61. W may be supplied.

  In the steam embodiment, the configuration of the gluing device 2 may be changed to another known configuration. For example, the warp yarn may be squeezed from the warp yarn after the warp yarn is sandwiched between a pair of squeezing rollers after the warp yarn is immersed in the paste solution in a size box (glue solution tank) that stores the paste solution.

In the above embodiment, each water supply unit 51 is provided with two rows of water discharge holes 54, but the number of rows of water discharge holes 54 may be arbitrarily changed. For example, it may be one row or three or more rows.
In the above embodiment, the joint 55 is provided in order to keep the width of the water discharge hole 54 constant. However, if the width of the water discharge hole 54 can be kept constant, the joint 55 is not provided. Also good.

  In the above embodiment, the joints 55 are alternately arranged with the joints 55 of the water discharge holes 54 in adjacent rows, but at least one location where the water W is discharged in the circumferential direction of the water supply device 51.
