Definitions

  • the present invention relates to a moistening apparatus in a sizing machine, which moistening apparatus passes warp threads that are wet with water through a pair of squeeze rollers, thereby squeezing water from the warp threads by means of squeezing effect of the squeeze rollers.
  • Moistening warp threads with water prior to application of sizing solution to the warp threads improves the efficiency of the size application and reduces the required amount of the sizing solution.
  • the moistened warp threads are dehydrated until the moisture content of the warp threads becomes a predetermined value. Thereafter, sizing solution is applied to the warp threads.
  • a device for moistening warp threads is disclosed in Japanese Laid-Open Patent Publication No. 2002-309477 .
  • the device of the publication includes an immersion roller immersed in water in a water tank and a squeeze roller that is located above the surface of the water in the water tank. The squeeze roller is pressed against the circumference of the immersion roller. Warp threads are wound about the immersion roller, and held between the circumference of the immersion roller and the squeeze roller. The warp threads are immersed in the water in the water tank and thus moistened.
  • a moistening apparatus in a sizing machine has a pair of squeeze rollers, which hold warp threads wet with water from above and below prior to application of sizing solution to the warp threads, thereby squeezing water from the warp threads.
  • the apparatus includes water supplying means that supplies water either to a circumferential surface of the roller that is located above the warp threads passing through between the pair of the rollers or to an upper side of the warp threads located upstream of the pair of the rollers.
  • the water supplying means has a water discharge hole.
  • the discharge hole is formed as a slit that extends along an axial direction of the water supplying means.
  • a sizing machine 1 includes a sizing apparatus 2 for applying sizing solution to warp threads T and a moistening apparatus 3 for moistening the warp threads T prior to the size application.
  • the sizing apparatus 2 has a size tank 11 for temporarily storing sizing solution N.
  • a size heating pipe 12 is provided in the size tank 11. Steam of a predetermined temperature is supplied to the interior of the sizing solution heating pipe 12 from a steam supply source 13. Steam supplied to the interior of the sizing solution heating pipe 12 heats the sizing solution N in the size tank 11 so that the sizing solution N is not hardened. The amount and temperature of the steam supplied to the size heating pipe 12 from the steam supply source 13 are adjusted such that the temperature of the sizing solution N in the size tank 11 is in a desired temperature range, for example, between 90°C and 95°C, inclusive.
  • the size tank 11 is connected to a size supply source 14 that stores the sizing solution N to be supplied to the size tank 11.
  • the size supply source 14 supplies the sizing solution N to the size tank 11.
  • the size supply source 14 is connected to the size tank 11 through a valve 15.
  • the valve 15 is controlled by a controller C1.
  • the controller C1 is connected to a level sensor 16 that detects the level of a liquid surface N1 of the sizing solution N in the size tank 11.
  • the controller C1 receives liquid surface level information from the level sensor 16 and controls the opening state of the valve 15 based on the liquid surface level information.
  • the controller C1 controls the valve 15 to open.
  • the sizing solution N is supplied to the size tank 11 from the size supply source 14.
  • the controller C1 controls the valve 15 to close. Accordingly, the supply of the sizing solution N from the size supply source 14 is stopped. The level of the liquid surface N1 of the sizing solution N in the size tank 11 is thus maintained in a certain range.
  • a size supply pipe 17 is connected to a bottom wall 111 of the size tank 11.
  • the size supply pipe 17 is branched into a first branch pipe 171 and a second branch pipe 172.
  • the first branch pipe 171 is connected to a first size supplying device 21, and the second branch pipe 172 is connected to a second size supplying device 22.
  • the size supplying devices 21, 22 are both cylindrical (pipe-shaped).
  • the size supply pipe 17 is provided with a size adjusting pump 18 between the bottom wall 111 of the size tank 11 and the branch portion of the first branch pipe 171 and the second branch pipe 172.
  • the size adjusting pump 18 pressure feeds the sizing solution N in the size tank 11 to the first size supplying device 21 and the second size supplying device 22 through the size supply pipe 17.
  • Size discharge holes 24 for discharging the sizing solution N are formed in the circumferential wall of each of the first and second size supplying devices 21, 22.

  • the second squeeze rollers 33, 34 are columnar and extend along the longitudinal direction (axial direction) of the second size supplying device 22.
  • the second squeeze roller 33 is arranged above the second squeeze roller 34.
  • the size discharge holes 24 of each size supplying device 21, 22 are arranged in a range S1, S2 of descending one quarter of a cycle after the top of the corresponding upper squeeze roller 31, 33 when viewed in the vertical direction. That is, the size discharge holes 24 of each size supplying device 21, 22, when viewed in the vertical direction, are in a range from the top 312, 332 of the corresponding squeeze roller 31, 33 to a position that is one quarter of a cycle away from the top 312, 332 along the rotation direction R1 (that is, the boundary K1, K2 between the upper half cycle and the lower half cycle).
  • the pair of the first squeeze rollers 31, 32 and the pair of the second squeeze rollers 33, 34 each tightly hold a great number of the warp threads T forming a sheet. That is, a great number of the warp threads T forming a sheet are passed through between the first squeeze rollers 31 and 32 and between the second squeeze rollers 33 and 34.

  • the transfer pathway of the warp threads T extends along the tangent of the circumferential surfaces 311, 321 of the squeeze rollers 31, 32 at the holding portion H1.
  • a circumferential surface 331 of the upper second squeeze roller 33 and a circumferential surface 341 of the lower second squeeze roller 34 hold the warp threads T at a holding portion H2, in which the circumferential surfaces 331, 341 face each other.

  • a size receiver 35 is provided directly below the squeeze rollers 31, 32, 33, 34.
  • a bottom wall 351 of the size receiver 35 is dented downward. The bottom wall 351 is at a position where it does not contact the squeeze rollers 32, 34.
  • a size recovery pipe 36 is connected to the lowest portion of the bottom wall 351. The size recovery pipe 36 extends to the size tank 11, which is located below the size receiver 35. The level of the liquid surface N1, at which supply of the sizing solution N from the size supply source 14 to the size tank 11 is stopped, is lower than the size receiver 35.
  • the moistening apparatus 3 will now be described.
  • the water tank 41 is connected to a water supply source 44 that stores the water W to be supplied to the water tank 41.
  • the water supply source 44 supplies the water W to the water tank 41.
  • the water supply source 44 is connected to the water tank 41 through a valve 45.
  • the valve 45 is controlled by a controller C2.
  • the controller C2 is connected to a level sensor 46 that detects the level of a liquid surface W1 of the water W in the water tank 41.
  • the controller C2 receives liquid surface level information from the level sensor 46 and controls the opening state of the valve 45 based on the liquid surface level information. Specifically, when the level of the liquid surface W1 of the water W in the water tank 41 falls below a predetermined level, the controller C2 controls the valve 45 to open. Accordingly, water is supplied to the water tank 41 from the water supply source 44.
  • the controller C2 controls the valve 45 to close. Accordingly, the supply of the water W from the water supply source 44 is stopped. The level of the liquid surface W1 of the water W in the water tank 41 is thus maintained in a certain range.

  • the water W in the water tank 41 is pressure fed to the water supplying device 51 by the water adjusting pump 48.
  • the flow rate of water supplied to the water supplying device 51 is readily adjusted, for example, by adjusting the rotation speed of the water adjusting pump 48.

  • Part of the water W that falls down the ascending half cycle range U3 of the lower squeeze roller 62 falls to an inner wall surface 652 of the bottom wall 651 of the water receiver 65.
  • the water W on the inner wall surface 652 is not deposited onto the lower squeeze roller 62. That is, the lower squeeze roller 62 does not pick up water on the inner wall surface 652.

  • the warp threads T are sent to the sizing apparatus 2.
  • the size adjusting pump 18 When the size adjusting pump 18 is activated while the squeeze rollers 31, 32, 33, 34 are rotating, the sizing solution N in the size tank 11 is pressure fed to the size supplying devices 21, 22 by the size adjusting pump 18.

  • the water discharge holes 54 are formed to have shapes that permit the water W to be uniformly supplied to the warp threads T. The water discharge holes 54 will now be described.
  • the water discharge holes 54 which are formed through the water supplying device 51, extend along the longitudinal direction (axial direction ) of the water supplying device 51, that is, the longitudinal direction (axial direction) of the squeeze rollers 61, 62.
  • Each water discharge hole 54 is formed like a slit having longer sides extending along the longitudinal direction of the water supplying device 51.
  • each water discharge hole 54 has a uniform width along the circumferential direction of the water supplying device 51 (in other words, a width in a direction perpendicular to the longitudinal direction of the water discharge holes 54). That is, each water discharge hole 54 has a slit-like (rectangular) shape extending along the longitudinal direction of the water supplying device 51 in a plan view.
  • Linking portions 55 are located in each water discharge hole 54 at predetermined intervals (in this embodiment, 25 mm).
  • the linking portions 55 maintain the width of the water discharge holes 54 (the width along the circumferential direction of the water supplying device 51) at a uniform value. That is, if each water discharge hole 54 is replaced by a single continuous slit extending along the longitudinal direction of the water supplying device 51, the width of the slit can hardly be maintained at a uniform value due to the physical properties of the material forming the water supplying device 51. However, by providing the linking portions 55, the width of each water discharge hole 54 is prevented from being altered by internal stress produced by the water W in the water supplying device 51.
  • each linking portion 55 along the longitudinal direction of the water supplying device 51 is significantly smaller than the interval between the linking portions 55 (25 mm, in this embodiment). In this embodiment, the length of each linking portion 55 along the longitudinal direction of the water supplying device 51 is 2 mm.
  • the water supplying device 51 has two water discharge holes 54 arranged along the circumferential direction of the water supplying device 51.
  • the linking portions 55 of each the water discharge hole 54 are formed to be alternately arranged in relation to the linking portions 55 of the other water discharge hole 54 in the longitudinal direction of the water supplying device 51. That is, with respect to the longitudinal direction of the water supplying device 51, at a position where a linking portion 55 is provided in one of the water discharge holes 54, no linking portion 55 is provided in the other water discharge hole 54.
  • the linking portions 55 are arranged such that, in any given area along the longitudinal direction of the water supplying device 51 along which the water discharge holes 54 extend, at least one section for discharging the water W is provided in the circumference. Thus, all the sections along the longitudinal direction of the water supplying device 51 discharge the water W.
  • the water supplying device 51 is arranged such that the water discharge holes 54 extend parallel with the longitudinal direction of the third squeeze rollers 61, 62. That is, the water discharge holes 54 are arranged such that the longitudinal direction is perpendicular to the advancing direction of the warp threads T.
  • the length of each water discharge hole 54 in the longitudinal direction is longer than the width of the sheet material formed of a great number of the arranged warp threads T.
  • the water discharge holes 54 discharge the water W to the outside.
  • the water discharge holes 54 extend along the axial direction of the water supplying device 51, and the widths of the water discharge holes 54 are maintained by the linking portions 55. Therefore, the water W discharged from the water discharge holes 54 forms a film of uniform thickness.
  • the linking portions 55 are alternately arranged in the two water discharge holes 54 in the longitudinal direction of the water supplying device 51.
  • the length of each linking portion 55 along the longitudinal direction of the water supplying device 51 is significantly short.
  • the water supplying device 51 thus substantially uniformly discharges the water W along the longitudinal direction. This prevents the water W from being unevenly supplied onto the warp threads T. All the warp threads T therefore have an appropriate water content.
  • This embodiment provides the following advantages.
  • the water receiver 65 is located directly below the third squeeze rollers 61, 62.
  • the water receiver 65 may be omitted, and the water tank 41 may be located directly below the third squeeze rollers 61, 62.
  • the level of the liquid surface W1 of water in the water tank 41 at which the supply of the water W from the water supply source 44 to the water tank 41 should be stopped needs to be set further lower than the lower squeeze roller 62, so that the lower squeeze roller 62 does not pick up the water W.
  • the liquid surface W1 functions as a receiving portion.
  • the water W is supplied to the circumferential surface 611 of the squeeze roller 61, which is the upper one of the third squeeze rollers 61, 62 receiving the warp threads T.
  • the water W may be supplied to the upper surface of the warp threads T in a portion upstream of the squeeze roller 61.
  • the configuration of the sizing apparatus 2 may be replaced by a known configuration.
  • it may be configured that the warp threads T are immersed in the sizing solution N in a size box (size tank) for storing the sizing solution N, and then, the sizing solution N is squeezed from the warp threads T by holding the warp threads T between a pair of squeeze rollers.
  • the water supplying device 51 has the linking portions 55 to maintain the widths of the water discharge holes 54 at a uniform value. However, as long as the widths of the water discharge holes 54 are maintained, the linking portions 55 do not need to be provided.
  • the linking portions 55 in each water discharge hole 54 are alternately arranged in relation to the linking portions 55 in the adjacent water discharge hole 54.
  • the positions of the linking portions 55 may be changed as long as, in any given area along the longitudinal direction of the water supplying device 51 along which the water discharge holes 54 are arranged, at least one section for discharging the water W is provided in the entire circumference.
  • the water supplying device 51 may have auxiliary holes for discharging the water W.
  • Each auxiliary hole is located in the same axial position as and in the vicinity of one of the linking portions 55.
  • the auxiliary holes permit an amount of water that has not been discharged due to the presence of the linking portions 55 to be discharged. Accordingly, the thickness of the film of the water W discharged by the water supplying device 51 is made further uniform.
  • the water supplying device 51 is arranged such that the longitudinal direction of the water discharge holes 54 (the axial direction of the water supplying device 51) is perpendicular to the advancing direction of the warp threads T.
  • the water discharge holes 54 may extend in a direction oblique with respect to the advancing direction of the warp threads T.
  • a moistening apparatus in a sizing machine for squeezing water from warp threads wet with water prior to application of sizing solution to the warp threads has a pair of squeeze rollers.
  • the squeeze rollers hold the warp threads from above and below.
  • the squeeze rollers have a water supplying device that supplies water either to a circumferential surface of the roller that is located above the warp threads passing through between the rollers or to an upper side of the warp threads located upstream of the rollers.
  • the water supplying device has water discharge holes, each of which is formed like a slit having longer sides extending along the longitudinal direction of the water supplying device.
