Description

TECHNICAL FIELD

The present invention relates to a warp sizing apparatus including a sizing tank in which a sizing liquid is stored, a first roll on which a warp sheet is wound, a second roll provided on a rear side with respect to the first roll so as to be circumscribed around the first roll on an upstream side in a traveling direction of the warp sheet, and a sizing liquid supply device configured to supply the sizing liquid to a circumscribed position of the first roll and the second roll, in which an end wall on a rear side of the sizing tank is located in front of a shaft center of the second roll.

BACKGROUND ART

Patent Literature 1 discloses a warp sizing apparatus including a sizing tank in which a sizing liquid is stored, and a sizing roll (first roll) on which a warp sheet is wound. In addition, the warp sizing apparatus is provided with squeeze rolls circumscribed around the sizing roll on front and rear sides of the sizing roll, respectively. Further, the warp sizing apparatus is provided with a sizing liquid supply device that supplies, from above, the sizing liquid to a circumscribed position of the sizing roll and the squeeze roll (second roll) on the rear side. In the warp sizing apparatus, the sizing liquid is supplied from the sizing liquid supply device to the circumscribed position and the warp sheet passes between the first roll the second roll, so that the sizing is performed on the warp sheet while the extra sizing liquid is squeezed from the warp sheet.
In addition, in the warp sizing apparatus, the sizing tank has a dimension greater than a presence range of the sizing roll and the two squeeze rolls with respect to a front-rear direction. Therefore, in the warp sizing apparatus, a size of the sizing tank is large, and an amount of the sizing liquid stored is large. For this reason, in the warp sizing apparatus, a used amount of the sizing liquid is large, so that the cost for sizing increases.
On the other hand, in the warp sizing apparatus disclosed in Patent Literature 2, the sizing tank is a small-sized one whose size in the front-rear direction is slightly larger than a diameter of the roll. Therefore, in the warp sizing apparatus, since an amount of the sizing liquid stored is smaller, as compared with the apparatus of Patent Literature 1, a used amount of the sizing liquid is suppressed.

Patent Literature 1: JP2003-96657A
Patent Literature 2: JP2013-2029A

In the meantime, the warp sizing apparatus of Patent Literature 2 also includes a sizing liquid supply device that supplies, from above, the sizing liquid to a circumscribed position of the sizing roll and the squeeze roll on the rear side. Note that, in the case of a warp sizing apparatus having such a sizing liquid supply device, including the apparatus of Patent Literature 1, the sizing liquid supplied from above is scattered rearward below the squeeze roll on the rear side, along with rotation of the roll. In addition, in the case in which the size of the sizing tank in the front-rear direction is small, as in the warp sizing apparatus of Patent Literature 2, the scattered sizing liquid is scattered to the rear of the sizing tank, so that the periphery of the warp sizing device is smudged.
Therefore, the present invention is to provide a warp sizing apparatus including the sizing liquid supply device as described above and a small-sized sizing tank and having a configuration by which it is possible to prevent as much as possible a periphery of the apparatus from being smudged due to a sizing liquid scattered rearward.

SUMMARY

In order to achieve the above object, a preamble of the present invention is a warp sizing apparatus including a sizing tank in which a sizing liquid is stored, a first roll on which a warp sheet is wound, a second roll provided on a rear side with respect to the first roll so as to be circumscribed around the first roll on an upstream side in a traveling direction of the warp sheet, a sizing liquid supply device configured to supply the sizing liquid to a circumscribed position of the first roll and the second roll, in which an end wall on a rear side of the sizing tank is located in front of a shaft center of the second roll. In addition, the warp sizing apparatus includes a plate-shaped receiving part provided to cover a presence range of the second roll with respect to a width direction below the second roll with respect to a vertical direction, and including an upward-facing receiving surface; and a collection part configured to collect the sizing liquid received by the receiving part, in which the receiving part is provided to be in contact with the end wall on the rear side of the sizing tank at a front end of the receiving surface, and has such a size that a rear end of the receiving surface is located behind the second roll, and the receiving surface is configured to be inclined downward toward the collection part.
In addition, in the present invention, the receiving part may include a restriction surface extending upward from the rear end of the receiving surface. Further, the collection part may include a collection path extending to cover a presence range of the sizing tank in the width direction, provided at a position in contact with an end wall on a front side of the sizing tank with respect to a front-rear direction, and formed with a collection hole in communication with an outside, and a guiding path extending in the front-rear direction on at least one of both sides of the sizing tank, provided at a position in contact with a side wall with respect to the width direction, and configured to make the receiving part and the collection path continuous with each other and to be inclined downward toward the collection path.
The preamble of the present invention is the warp sizing apparatus including the sizing tank provided so that the end wall on the rear side is located in front of the shaft center of the second roll, i.e., the warp sizing apparatus including such a small-sized sizing tank. The warp sizing apparatus includes the receiving part provided to cover the presence range of the second roll in the width direction below the second roll. In addition, the receiving part is provided to be in contact with the end wall on the rear side of the sizing tank at the front end of the upward-facing receiving surface. Further, the receiving part has such a size that the rear end of the receiving surface is located behind the second roll.
Thereby, even when the sizing liquid supplied from the sizing liquid supply device to a circumscribed position of the first roll and the second roll is scattered to the rear of the sizing tank due to the rotation of the roll as described above, the scattered sizing liquid (scattered sizing liquid) is received on the receiving surface of the receiving part. Therefore, the periphery of the warp sizing apparatus is prevented as much as possible from being smudged due to the scattered sizing liquid. Furthermore, as described above, since the receiving part is provided so that the front end of the receiving surface is in contact with the sizing tank (end wall on the rear side), i.e., the front end of the receiving surface is located within the presence range of the sizing tank with respect to the vertical direction, it is possible to avoid an increase in size of the entire warp sizing apparatus in the vertical direction.
Note that, in the present invention, the warp sizing apparatus further includes the collection part configured to collect the sizing liquid received by the receiving part, and the receiving part is configured so that the receiving surface is inclined downward toward the collection part. Thereby, the scattered sizing liquid received on the receiving surface as described above flows along the inclined receiving surface, reaches the collection part, and is collected in the collection part.
Further, in the present invention, when the receiving part is configured to have the restriction surface extending upward from the rear end of the receiving surface, the scattered sizing liquid is also received on the restriction surface, as compared with a configuration of a warp sizing apparatus in which the scattered sizing liquid is received only with the upward-facing receiving surface. Therefore, a length of the receiving surface in the front-rear direction can be made shorter, and a size of the receiving part in the front-rear direction can be made more compact.
Further, a general warp sizing apparatus is provided with a configuration for collecting the sizing liquid (overflowed sizing liquid) overflowing from the sizing tank as the sizing liquid is supplied into the sizing tank. Further, in the present invention, when the collection part is configured to include the collection path provided in front of the sizing tank and the guiding path provided on at least one of both sides of the sizing tank, the receiving part and the collection path are made continuous with the guiding path, and the guiding path is configured to be inclined downward toward the collection path, the collection part for collecting the scattered sizing liquid also functions as a configuration for collecting the overflowed sizing liquid. That is, the scattered sizing liquid and the overflowed sizing liquid are collected in the common collection part. Therefore, as compared with a case in which a warp sizing apparatus is configured so that the collection of the scattered sizing liquid and the collection of the overflowed sizing liquid are performed at different places, the configuration of the entire warp sizing apparatus can be made simpler.

DESCRIPTION OF EMBODIMENTS

Hereinafter, one embodiment of a warp sizing apparatus to which the present invention is applied will be described with reference to FIGS. 1 to 3.
A warp sizing apparatus 1 includes a sizing tank 3 in which a sizing liquid S is stored, a sizing roll 11 on which a warp sheet T is wound and which is immersed in the sizing liquid S, and a first squeeze roll 13 and a second squeeze roll 15 circumscribed around the sizing roll 11. However, the sizing roll 11, the first squeeze roll 13, and the second squeeze roll 15 are rolls having substantially the same dimensions in axis line directions thereof. In addition, the warp sizing apparatus 1 includes a sizing liquid supply device 20 that supplies, from above, the sizing liquid S to a circumscribed position of the sizing roll 11 and the first squeeze roll 13. Note that, in the present embodiment, the sizing roll 11 corresponds to the first roll referred to in the present invention, and the first squeeze roll 13 corresponds to the second roll.
The sizing roll 11 is a roll on which the warp sheet T is wound. The sizing roll 11 is rotatably supported with respect to a frame (not shown) of the warp sizing apparatus 1 by support shafts 12 and 12 attached to both ends of the sizing roll. In addition, the sizing roll 11 is provided such that a lower part thereof is in a state of being immersed in the sizing liquid S stored in the sizing tank 3.
Note that the warp sizing apparatus 1 includes a drive mechanism (not shown) configured to rotationally drive the sizing roll 11. Thereby, the sizing roll 11 is rotationally driven positively in conformity with advancing of the warp sheet T. The warp sheet T is guided in the form of being wound onto the sizing roll 11, and is immersed in the sizing liquid S and is impregnated with the sizing liquid S during such guiding.
The second squeeze roll 15 is a roll for squeezing the sizing liquid S impregnated in the warp sheet T, and is provided in arrangement of being positioned on a front side with respect to the sizing roll 11. In addition, the second squeeze roll 15 is rotatably supported with respect to the frame by support shafts 16 and 16 attached to both ends of the second squeeze roll, in a direction in which the axis line direction of the second squeeze roll is made to coincide with the axis line direction of the sizing roll 11 (width direction of the warp sizing apparatus 1). Note that the second squeeze roll 15 is supported with respect to the frame via a pressing mechanism (not shown), and is provided to be circumscribed in a state of being pressed against the sizing roll 11. Therefore, the second squeeze roll 15 is adapted to rotate as the sizing roll 11 is rotationally driven as described above.
The warp sheet T wound on the sizing roll 11 as described above passes between the sizing roll 11 and the second squeeze roll 15 circumscribed as described above, and is then pulled out toward an outside. In addition, when passing between the sizing roll 11 and the second squeeze roll 15 as such, the extra sizing liquid S is squeezed from the warp sheet T impregnated with the sizing liquid S as described above.
The first squeeze roll 13 is provided in arrangement of being positioned on a rear side with respect to the sizing roll 11. The first squeeze roll 13 is also rotatably supported with respect to the frame by support shafts 14 and 14 attached to both ends thereof, in a direction in which the axis line direction of the first squeeze roll is made to coincide with the width direction. In addition, the first squeeze roll 13 is also rotatably supported with respect to the frame via the pressing mechanism and is circumscribed in a state of being pressed against the sizing roll 11, like the second squeeze roll 15. Therefore, the first squeeze roll 13 is also adapted to rotate as the sizing roll 11 is rotationally driven.
Note that the sizing tank 3 is a housing with an open upper surface and is formed by a bottom plate 4, front and rear end walls 5 and 6, and left and right side walls 7 and 7. In addition, the sizing tank 3 is provided so that the end wall 5 on the front side is located slightly in front of the circumscribed position of the sizing roll 11 and the second squeeze roll 15 with respect to the front-rear direction of the warp sizing apparatus 1. Further, the sizing tank 3 has such a size in the front-rear direction that the end wall 6 on the rear side is located slightly behind the circumscribed position of the sizing roll 11 and the first squeeze roll 13. Therefore, the sizing tank 3 is a sizing tank configured so that the end wall 6 on the rear side is located in front of the shaft center of the first squeeze roll 13 (second roll), and is a small-sized sizing tank capable of immersing only the sizing roll 11.
Further, in the warp sizing apparatus 1, the first squeeze roll 13 is circumscribed around the sizing roll 11 as described above, so that a wedge-shaped region, which is a wedge-shaped gap, is formed between the sizing roll 11 and the first squeeze roll 13 (above the circumscribed position). In addition, a sizing liquid supply device 20 for supplying the sizing liquid S toward the wedge-shaped region is provided above the wedge-shaped region.
The sizing liquid supply device 20 is configured to include a sizing liquid supply pipe 22 extending along the axis line direction of the sizing roll 11 and a nozzle 24 attached to the sizing liquid supply pipe 22. In addition, a supply pipe 26 is connected to one end portion of the sizing liquid supply pipe 22 (which is not shown), and the size liquid S is supplied from a supply source 28 via the supply pipe 26. Thereby, in the warp sizing apparatus 1, the size liquid S is supplied to the wedge-shaped region via the sizing liquid supply device 20, so that a sizing liquid pool 18 in which the size liquid S is retained is formed in the wedge-shaped region.
In addition, the warp sheet T is guided in the form of being wound onto the first squeeze roll 13, passes between the sizing roll 11 and the first squeeze roll 13 circumscribed as described above, and is then wound on the sizing roll 11 as described above. Then, the warp sheet T passes through the sizing liquid pool 18 formed between both the rolls, so that the sizing liquid S is impregnated in the warp sheet T. When the warp sheet T impregnated with the sizing liquid S passes between the sizing roll 11 and the first squeeze roll 13, the extra sizing liquid S is squeezed from the warp sheet T.
In the warp sizing apparatus 1 as described above, in the present invention, the warp sizing apparatus includes a plate-shaped receiving part that is provided to cover a presence range of the second roll with respect to the width direction below the second roll with respect to the vertical direction, and has an upward-facing receiving surface, and a collection part that collects the sizing liquid received by the receiving part. The receiving part is provided to be in contact with an end wall on a rear side of the sizing tank at a front end of the receiving surface, and has such a size that a rear end of the receiving surface is located behind the second roll, and the receiving surface is configured to be inclined downward toward the collection part. In addition, the present embodiment is an example in which a collection part 40 that collects the sizing liquid S received by a receiving surface 32a of a receiving part 30 also functions as a configuration for collecting sizing liquid (overflowed sizing liquid) overflowing from the sizing tank 3. The warp sizing apparatus 1 of the present embodiment will be described in detail below.
The warp sizing apparatus 1 includes a receiving part 30 that receives the sizing liquid (scattered liquid) scattered to the rear of the sizing tank 3 by rotation of the first squeeze roll 13, and a collection part 40 that collects the scattered sizing liquid received by the receiving part 30.
First, as for the receiving part 30, the receiving part 30 of the present embodiment is configured to have, in addition to the receiving surface 32a as described above, a restriction surface 34a extending upward from a rear end of the receiving surface 32a. In addition, the receiving part 30 is formed as a plate-shaped member. Therefore, the receiving part 30 is configured by a receiving portion 32, which is a plate-shaped portion having the receiving surface 32a, and a restriction portion 34 having the restriction surface 34a. Note that the restriction portion 34 is continuous with the receiving portion 32 at an angle in a plate thickness direction due to a relationship between the receiving surface 32a and the restriction surface 34a. Thereby, the receiving part 30 is formed in a substantial L-shape as a whole. In addition, the receiving part 30 is provided to be in contact with the end wall 6 on the rear side of the sizing tank 3 on a front end (end edge on an opposite side to the restriction portion 34 side) of the receiving surface 32a (receiving part 30) with the receiving surface 32a facing upward. For reference, in the present embodiment, the receiving part 30 and the sizing tank 3 are fixed by welding or the like at their contact portions.
As for the receiving part 30, more specifically, the receiving portion 32 forms a rectangular shape in a plan view, and has a shape in which a front end (rear end) of the receiving surface 32a is a long side. The receiving portion 32 has substantially the same size as the size in the width direction of the sizing tank 3 with respect to its long side direction (direction parallel to the front end in a plan view). In addition, the receiving portion 32 has such a size that the rear end of the receiving surface 32a is located behind the first squeeze roll 13 in a state of being provided as described above, with respect to the short side direction that is a direction orthogonal to the long side direction in a plan view.
The restriction portion 34 forms a substantially rectangular shape when seen in the plate thickness direction, and has a shape in which an end edge continuous with the receiving portion 32 is a long side. That is, the restriction portion 34 (restriction surface 34a) has such a shape that the direction of the long side thereof is made to coincide with the direction of the long side of the receiving portion 32 (receiving surface 32a). In addition, the size of the restriction portion 34 (restriction surface 34a) in the long side direction is larger than the size of the receiving portion 32 in the long side direction so that positions of both side edges of the restriction portion coincide with positions of both side edges of the collection part 40 described later. However, the receiving portion 32 and the restriction portion 34 have a positional relationship in which both centers coincide with each other with respect to the long side direction. In addition, the restriction portion 34 is formed integrally with the receiving portion 32. Note that the long side direction of the receiving portion 32 and the long side direction of the restriction portion 34 coincide with the width direction of the warp sizing apparatus 1. Therefore, in the below, the long side direction is rephrased and described as the width direction.
Although the receiving part 30 constituted as such is provided for the sizing tank 3 in the form described above, regarding the arrangement in the width direction, the receiving part 30 is provided with its center coinciding with a center of the sizing tank 3. Note that the size of the receiving portion 32 (receiving surface 32a) in the width direction is substantially the same as the size of the sizing tank 3 in the width direction, as described above. Therefore, a presence range of the receiving part 30 in the width direction is made to include a presence range of the first squeeze roll 13. Regarding the arrangement in the front-rear direction, the receiving part 30 is provided such that it is in contact with the sizing tank 3 at the front end of the receiving portion 32, as described above, and the rear end of the receiving portion 32 is located behind the first squeeze roll 13. Therefore, the presence range of the receiving part 30 in the front-rear direction also includes the presence range of the first squeeze roll 13.
In addition, in the present embodiment, the receiving part 30 (receiving portion 32) is provided so that the receiving surface 32a is inclined downward from the rear toward the front. Further, the receiving portion 32 is formed in a slightly bent shape at the center so as to be inclined downward from the center toward both side edges with respect to the width direction.
Next, as for the collection part 40, the collection part 40 of the present embodiment is configured to have a collection path 42 provided to extend in the width direction in front of the sizing tank 3, and a pair of guiding paths 44 and 44 that extend in the front-rear direction at both sides of the sizing tank 3 and make the receiving part 30 and the collection section 42 continuous with each other.
Each guiding path 44 has a plate shape, and is provided to extend forward from a lower end of the restriction portion 34 of the receiving part 30 on each of both sides of the sizing tank 3, as described above. In addition, each guiding path 44 is provided to be inclined forward from the rear at the same angle as that of the receiving portion 32. Further, each guiding path 44 is provided to be in contact with the side wall 7 of the sizing tank 3 with respect to the width direction. Therefore, each guiding path 44 is provided in such a form that its inner side edge is butted against the side edge of the receiving portion 32 of the receiving part 30:
Note that each guiding path 44 has such a size that an outer side edge substantially coincides with a side edge of the restriction portion 34 with respect to the width direction. In addition, each guiding path 44 has such a size that a front end substantially coincides with the end wall 5 on the front side of the sizing tank 3 with respect to the front-rear direction. That is, a position of the front end of each guiding path 44 is substantially the same as that of the end wall 5 on the front side of the sizing tank 3 with respect to the front-rear direction.
In addition, the collection path 42 is configured by a rectangular plate-shaped bottom wall and both vertical walls, and is formed so that its cross section forms a U-shaped gutter shape. Further, a size of the collection path 42 in a longitudinal direction (long side direction of the bottom wall and vertical wall) is substantially the same as the size of the restriction portion 34 of the receiving part 30 in the long side direction (the width direction), and is larger than the size of the sizing tank 3 in the width direction. Further, the collection path 42 is provided in such a form that its longitudinal direction is made to coincide with the width direction and its center is made to coincide with the center of the sizing tank 3 with respect to the width direction. Thereby, a presence range of the collection path 42 in the width direction includes a presence range of the sizing tank 3. In addition, positions of both end edges of the collection path 42 are substantially the same as the side edges of the restriction portion 34 and the outer side edges of the guiding paths 44 with respect to the width direction.
Regarding the arrangement in the front-rear direction, the collection path 42 is provided to be in contact with the end wall 5 on the front side of the sizing tank 3 at an upper edge of the vertical wall on the rear side and to be continuous with the front end of each guiding path 44 at the upper edge. Therefore, the collection path 42 is continuous with the receiving portion 32 via both the guiding paths 44 and 44. For reference, in the present embodiment, the collection path 42 and both the guiding paths 44 and 44 are integrally formed. In addition, both the guiding paths 44 and 44 are also formed integrally with the receiving part 30 (the receiving portion 32 and the restriction portion 34).
In addition, the bottom wall of the collection path 42 is formed in a slightly bent shape at the center so as to be inclined downward from both end edges toward the center with respect to the longitudinal direction (the width direction). The collection path 42 has a through-hole 42a that penetrates the bottom wall in the vertical direction at a position of the center of the bottom wall in the longitudinal direction. Note that the through-hole 42a is connected to a collection device 70 for the sizing liquid S provided outside via a pipe or the like (not shown). Thereby, the through-hole 42a is adapted to function as a collection hole for collecting the sizing solution S.
For reference, in the shown example, the warp sizing apparatus 1 has a plate-shaped wall part 50 extending forward from an upper edge of a vertical wall on the front side of the collection path 42, and extending upward from a position in front of the second squeeze roll 15. In addition, a size of the wall part 50 in the width direction is substantially the same as the size of the collection path 42 in the longitudinal direction. Thereby, the warp sizing apparatus 1 has a space, which is defined by the wall part 50 and the restriction portion 34 of the receiving part 30 in the front-rear direction and in which portions of the sizing roll 11, the first squeeze roll 13, and the second squeeze roll 15 are present.
Further, the warp sizing apparatus 1 includes a pair of side frames 60 and 60 provided in the form of closing both sides of the space. Note that each side frame 60 is greater than a distance from the upper edge of the restriction portion 34 to the bottom wall of the collection path 42 in the vertical direction, and is slightly greater than a distance from the upper edge of the restriction portion 34 to then upper edge of the wall part 50 in the front-rear direction. Both the side frames 60 and 60 are provided in such a form that they, on their inner side surfaces, are in contact with the side edges of the restriction portion 34, the outer side edges of the guiding path 44, the end edges of the collection path 42 and the side edges of the wall part 50, which are at the same position in the width direction as described above.
Operations of the warp sizing apparatus 1 of the present embodiment configured as described above are as follows. First, during an operation of the warp sizing apparatus 1 (during warp sizing), the sizing liquid S supplied from the sizing liquid supply device 20 to the circumscribed position of the sizing roll 11 and the first squeeze roll 13 is scattered to the rear of the sizing tank 3 by rotation of the squeeze roll 13, as described above. However, in the warp sizing apparatus 1, the scattered sizing liquid S is received by the receiving part 30 (receiving portion 32 and restriction portion 34) provided behind the sizing tank 3 in the form of being continuous with the sizing tank 3. Since the receiving portion 32 of the receiving part 30 is formed to be inclined in the width direction as described above, the received sizing liquid S flows toward the side edge side in the width direction on the receiving surface 32a of the receiving portion 32.
In addition, since the guiding path 44 of the collection part 40 is provided in the form of being butted (continuous) against the side edge of the receiving portion 32 (receiving surface 32a) and the guiding path 44 is formed to be inclined forward, the sizing liquid S flowing on the receiving surface 32a reaches the corresponding guiding path 44, and then flows down toward the front. Note that since the side frame 60 is provided as described above, the flow of the sizing liquid S toward the width direction is blocked by the side frame 60.
Since the collection path 42 is provided in the form of being continuous with the front end of the guide path 44, the sizing liquid S flowing on the guide path 44 flows down onto the bottom wall of the collection path 42. In addition, since the bottom wall of the collection path 42 is formed to be inclined in the width direction (toward the through-hole 42a) as described above, the sizing liquid S on the bottom wall flows toward the through-hole 42a, and is collected to the collection device 70 via the pipe or the like.
In this way, according to the warp sizing apparatus 1 of the present embodiment, the sizing liquid (scattered sizing liquid) scattered to the rear of the sizing tank 3 by the rotation of the first squeeze roll 13 is received by the receiving surface 32a of the receiving part 30. Therefore, the periphery of the warp sizing apparatus is prevented as much as possible from being smudged due to the scattered sizing liquid. In addition, as described above, since the receiving part 30 is provided so that the front end of the receiving surface 32a is in contact with the sizing tank 3 (end wall 6 on the rear side), i.e., the front end of the receiving surface 32a is located within the presence range of the sizing tank 3 with respect to the vertical direction, an increase in size of the entire warp sizing apparatus in the vertical direction is avoided.
Further, since the receiving part 30 is configured to have the restriction portion 34 (restriction surface 34a) as described above, the sizing liquid scattering at a position higher than the receiving surface 32a is received by the restriction surface 34a. Thereby, as compared with a configuration in which the scattered sizing liquid is received only by the receiving surface 32a, a length of the receiving surface 32a in the front-rear direction can be made shorter, and a size of the receiving part 30 in the front-rear direction can be made more compact.
Further, since the collection part 40 is configured as described above, the sizing liquid (overflowed sizing liquid) overflowing from the sizing tank 3 is also collected by the collection part 40, i.e., the collection part 40 also functions as a configuration for collecting the overflowed sizing liquid, the configuration of the entire warp sizing apparatus becomes simpler.
More specifically, in the warp sizing apparatus, it is common that a new sizing liquid is always or periodically supplied to the sizing tank. When the sizing liquid is supplied in this way, the sizing liquid overflows from the sizing tank. In contrast, in the warp sizing apparatus 1 of the present embodiment, the collection part 40 (guiding path 44, collection path 42) is provided to be in contact with the sizing tank 3 from the sides and front of the sizing tank 3. Thereby, the overflowed sizing liquid is received by the guiding path 44 and collection path 42 of the collection part 40, and flows towards the through-hole 42a, similarly to the scattered sizing liquid received by the receiving part 30 (receiving surface 32a). Therefore, in the configuration, the collection part 40 also functions as a configuration for collecting the overflowed sizing liquid, and therefore, since there is no need to provide a configuration for collecting the overflowed sizing liquid separately from the collection part 40, the configuration of the entire warp sizing apparatus becomes simpler.
In the above, one embodiment (hereinafter, referred to as 'above embodiment') of the warp sizing apparatus to which the present invention is applied has been described. However, the present invention is not limited to the configuration described in the above embodiment, and can also be implemented by other embodiments (modified embodiments) as described below.

(1) As for the receiving part, in the above embodiment, the receiving part 30 is formed in a substantial L-shape as a whole and is configured by the receiving portion 32 including the upward-facing receiving surface 32a, and the restriction portion 34 including the restriction surface 34a extending upward from the rear end of the receiving surface 32a. However, in the present invention, the receiving part may be configured only by the receiving portion, without the restriction surface (restriction portion). However, in this case, the size of the receiving portion in the front-rear direction needs to be such that the receiving surface can receive as much as possible the sizing liquid (scattered sizing liquid) scattered rearward as described above. In addition, as for the end face (receiving surface) of the receiving portion, the receiving portion is not limited to being formed so that the receiving surface is flat as in the above embodiment, and the receiving portion may be formed so that the receiving surface is curved.
(2) As for the inclination of the receiving portion (receiving surface) of the receiving part and the collection part, in the above embodiment, the receiving portion 32 is formed in a bent shape (in an inverted V shape) at the center so as to be inclined downward from the center toward both side edges with respect to the width direction. In addition, both sides of the receiving portion 32 are provided with the pair of guiding paths 44 and 44 of the collection part 40 in the form of being continuous with both side edges thereof. Further, in the above embodiment, the receiving part 30 (receiving portion 32) is provided so that the receiving surface 32a is inclined downward from the rear toward the front in the front-rear direction. However, in the present invention, the configuration of the receiving portion (receiving surface) and the configuration of the collection part accompanying the same are not limited to those of the above embodiment.

For example, the receiving portion may be formed to be inclined downward from a side edge on one side toward a side edge on the other side with respect to the width direction in a state (installed state) in which the receiving part is installed to the warp sizing apparatus. In this case, the guiding path of the collection part is provided only at the side edge on the other side of the receiving portion.
Further, the receiving portion may be formed in the form of being bent (in a V-shape) at the center so as to be inclined downward from both side edges toward the center with respect to the width direction. In this case, as a configuration for collecting the scattered sizing liquid received by the receiving portion (receiving surface), the center of the receiving portion may be formed with a through-hole penetrating in the vertical direction, and the through-hole and the collection device for sizing liquid may be connected by a pipe or the like. In this case, the through-hole corresponds to the collection part. Note that, in the case where the receiving portion is bent at a portion as in the above embodiment or in this way, the bending position is not limited to the center in the width direction, and may be a position on a side edge side of the center.
Further, the receiving part (receiving portion) may be provided so that the receiving surface is inclined downward from the front toward the rear with respect to the front-rear direction. Note that, in this case, when the collection part is configured in the form of causing the scattered sizing liquid to flow to the front collection path via the guiding path as in the above embodiment, the collection part may be provided with a portion, which restricts the scattered sizing liquid flowing on a guiding path adjacent to the receiving portion in the width direction from flowing down to an inner side in the width direction, within a range of the guiding path. Further, the receiving part (receiving portion) may be provided in such a form that the receiving surface is not inclined in the front-rear direction, when the receiving surface is formed to be inclined with respect to the width direction.
(3) As for the collection part, in the above embodiment, the collection part 40 also functions as a configuration for collecting the sizing liquid (overflowed sizing liquid) overflowing from the sizing tank 3. However, in the present invention, the collection part may be provided to collect only the scattered sizing liquid.
For example, in the case in which the receiving part is configured as in the above embodiment, the collection part may be provided to collect, at the rear of the sizing tank, the scattered sizing liquid flowing toward both sides of the receiving portion (receiving surface). Specifically, flow paths each formed similarly to the guiding path in the above embodiment and having a front end provided substantially at the same position as the rear end of the sizing tank 3 in the front-rear direction are provided on both sides of the receiving portion. Further, a front end portion of the flow path is formed with a through-hole penetrating in a plate thickness direction. In addition, the through-hole and the collection device for sizing liquid may be connected by a pipe or the like. In this case, the flow paths provided on both sides of the receiving portion and formed with the through-holes correspond to the collection part.
In addition, as described above, in the case in which the receiving part (receiving portion) is provided such that the receiving surface is inclined downward from the front toward the rear, the receiving part may be configured without a restriction portion, then a collection part may be provided to collect the scattered sizing liquid flowing (flowing down) rearward from the rear end of the receiving part (receiving surface). In this case, for example, a gutter member extending over the presence range of the receiving portion in the width direction is provided near the rear end of the receiving portion. The gutter member may be connected to the collection device, and the scattered sizing liquid may be collected by the collection device. In this case, the gutter member corresponds to the collection part.
(4) As for the warp sizing apparatus that is the preamble, in the above embodiment, the warp sizing apparatus 1 is configured in such a form that the sizing roll 11 is immersed in the sizing liquid S in the sizing tank 3, and the first and second squeeze rolls 13 and 15 are circumscribed around the sizing roll 11 so as to sandwich the path of the warp sheet T therebetween. However, the warp sizing apparatus to which the present invention is applied is not limited to such a configuration.
For example, the warp sizing apparatus may also be configured such that the second squeeze roll is also immersed in the sizing liquid S in the sizing tank, in addition to the sizing roll. However, in this case, the sizing tank is dimensioned to include the sizing roll and the second squeeze roll in the front-rear direction. In addition, the warp sizing apparatus may also be configured such that only the second squeeze roll is immersed in the sizing liquid S in the sizing tank.
The present invention is not limited to the above embodiment, and can be variously changed without departing from the gist of the present invention.
