Description

  The present invention comprises a plurality of gluing processing devices in which a plurality of warps that have been pretreated using a pretreatment device are divided into a plurality of warp groups, and the warps of each warp group are individually arranged corresponding to the warp groups. The present invention relates to a warp gluing method and apparatus for gluing.

  As one of the warp sizing methods and devices, pretreatment is performed by attaching a high-temperature pretreatment liquid (pretreatment glue liquid or water) to a plurality of warps arranged in a sheet shape in a pretreatment device, and squeezing. Thereafter, a technique is known in which a glue solution is attached to a plurality of pretreated warp yarns in a pasting apparatus (see Patent Documents 1 and 2).

  In the former prior art, a paste liquid having the same concentration as the paste liquid of the pasting apparatus is used as the pretreatment liquid. The warp yarn is immersed in the pretreatment liquid in the pretreatment apparatus, and the pretreatment liquid is a fiber. Impurities such as cotton wax that penetrate into the inside of the yarn and prevent adhesion of glue contained in the warp yarn enter the pretreatment liquid. Thereafter, the pretreatment liquid is squeezed, so that impurities such as cotton wax are squeezed out of the warp yarn together with the pretreatment liquid and enter the pretreatment liquid in the pretreatment liquid basket of the pretreatment apparatus. For this reason, since the pretreatment liquid contains many impurities, in the above-mentioned conventional apparatus, when the warp yarn to which the impurities and the pretreatment liquid are attached is immersed in the glue liquid of the subsequent gluing treatment apparatus and glued to the warp, A part of the pretreatment liquid containing impurities adhering to the yarn leaves the warp and mixes with the paste liquid.

  As a result, the glue liquid is quickly soiled by the impurities brought in together with the pretreatment liquid by the warp, so that the warp thread passed through the soiled paste liquid is glued by the glue liquid in a state where the impurities are attached.

  In addition, when pre-treatment paste liquid having a lower glue concentration than the paste liquid for paste treatment or high-temperature water not containing paste liquid is used for the pre-treatment as in the latter prior art, The paste liquid is not only soiled by impurities, but also the paste concentration of the paste liquid is rapidly reduced by the pretreatment liquid brought in by the warp. Therefore, it is difficult to manage the paste concentration in the pasting apparatus, and as a result, it adheres to the warp. It becomes difficult to maintain the adhesion rate of the glue at a predetermined value.

  In any case, since the warp is moved in a state of being arranged at high density in the pretreatment device, the pasting is performed in a state where the interval between the adjacent warps is narrow. As a result, sufficient and uniform pasting cannot be performed on the pretreated warp.

  In addition, since it is dried without sufficient spacing between the warps, not only the drying efficiency cannot be improved, but also the warps interfere with each other, and the warps adhere to each other by glue, or the separated warps are separated. Generation of fluff that has been fluffed by generation or glue occurs. Adhesion between warps and an increase in fluff cause poor opening of the loom and impair the weaving property.

  On the other hand, it is also conceivable that two processing machines each including a pre-processing device and a gluing processing device are provided, and a plurality of warps are divided into two warp sheets for gluing. In this case, the adjacent warp yarns from the yarn feeder are generally divided into one and the other warp sheet. Each pretreatment device squeezes the warp of the warp sheet between a dipping roll and a squeeze roll, and the pretreatment liquid accumulates between the warps in the gap between the rollers.

  However, if the pre-processing and the gluing process are performed for each warp sheet, the number of warps to be squeezed in each pre-processing device is small, so that the interval between adjacent warps is widened. It accumulates between the warp yarns on the surface, and the pretreatment liquid is carried by the warp yarns to the gluing processing device.

  For this reason, even in the conventional technique of gluing in two warp sheets, it is unavoidable that the glue liquid of the gluing processing apparatus is quickly soiled and the glue concentration in the glue liquid processing apparatus is rapidly reduced. As a result, paste concentration management becomes difficult, and impurities adhere to the warp.

  An object of the present invention is to make it difficult for the pretreatment liquid of the pretreatment apparatus to be mixed with the paste liquid of the subsequent gluing treatment apparatus.

  In the gluing method according to the present invention, the pretreatment liquid is attached to a plurality of warp yarns arranged in a sheet form and subjected to pretreatment, and the pretreatment is performed to divide the plurality of warp yarns into a plurality of warp groups. And performing a gluing process for attaching a glue solution to each of the divided warp groups.

  A first gluing device according to the present invention includes a pretreatment device that attaches and squeezes a pretreatment liquid to a plurality of warps, and a plurality of warps pretreated by the pretreatment device to divide the warp into a plurality of warp groups. A pretreatment warp splitting device disposed downstream of the pretreatment device in the warp movement direction; and a downstream of the pretreatment warp splitting device in the movement direction so as to individually adhere the paste liquid to the divided warp group. And a plurality of gluing processing devices arranged on the side.

  A second gluing device according to the present invention includes a yarn feeding side warp dividing device that divides a plurality of warps from a yarn feeding device arranged in a sheet shape into a plurality of warp groups, and the yarn feeding side in the warp moving direction. A plurality of processing machines disposed downstream of the warp splitting device, each of which applies a pretreatment liquid to the warp to squeeze the pretreatment device and the paste liquid to adhere to the warp passed through the pretreatment device; A plurality of processing machines provided with a pasting processing device disposed downstream of the preprocessing dividing device in the moving direction, and warps pretreated by the preprocessing device of the processing machine located on the most upstream side The pre-processing device and the gluing process of a processing machine located upstream of the plurality of processing machines in the moving direction so as to be divided into a plurality of warp groups individually glued in a gluing processing device of a plurality of processing machines Placed between the device And a pretreatment warp dividing device.

  In the present invention, it is possible to divide a plurality of warps into a plurality of warp groups after pre-treatment, and perform a pasting process with a glue solution for each warp group.

  Therefore, according to the present invention, the number of warp yarns to be pre-processed is larger than that in the case where the warp yarn from the yarn feeding device is divided into a plurality of warp groups and pre-processed for each warp group. , The spacing between adjacent warps is narrow, the amount of pretreatment liquid collected between adjacent warps in the gap between the rollers is small, and the amount of pretreatment liquid carried by the warp to the glue liquid of the gluing processing device is small. Become.

  As a result of the above, it is easy to manage the glue concentration by slowing down the dilution of the glue liquid in the gluing processing apparatus, even when using a paste liquid lower than the glue density of the gluing apparatus as the pretreatment liquid or using water. Thus, the warp can be easily maintained at a predetermined adhesive adhesion rate.

  In addition, the impurities that have adhered to the warp yarn are present in the pretreatment liquid, but the pretreatment liquid that adheres to the warp yarn is transported to the glue liquid of the gluing processing device and is less likely to be quickly soiled by impurities in the glue liquid. Can be suppressed.

  Furthermore, since the warp density in each divided warp group is small, in the gluing process, the warp can be glued with a wide warp interval, and sufficient and uniform gluing can be achieved.

  After performing a pasting process for a plurality of warp groups for each warp group, a drying process may be performed separately for each warp group.

  It is possible to dry while widening the warp interval, to increase the drying efficiency, to suppress the interference between the warps, to separate the loom opening failure caused by the sticking of the warp yarn by glue, and the fixed warp It is possible to suppress both the opening defect of the loom due to the generation of fluff due to the exposure and the exposure of the fluff that has been fluffed with glue.

  The division process may include bringing a warp of a warp group to be divided into contact with a guide roll for each warp group.

  The pretreatment liquid may include a paste liquid or water having a paste concentration equal to or lower than that of the second paste liquid. However, when a paste liquid having the same paste concentration as the paste liquid of the paste processing apparatus is used as the pretreatment liquid, the pretreatment liquid is conveyed to the paste liquid of the paste processing apparatus by warp. The paste liquid in the processing apparatus is not diluted.

  The pretreatment warp splitting device may be provided with a plurality of guide rolls arranged in correspondence with the pasting processing device and in contact with the corresponding warp group, and further arranged vertically. You may provide the 1st and 2nd guide roll which guides one of the divided | segmented several warp groups so that it may pass through the lower side of the pasting processing apparatus located in an upstream.

  In another gluing device according to the present invention, as described above, a plurality of warp yarns are divided into a plurality of warp yarn groups by the pretreatment warp dividing device, and one warp group is upstream of the plurality of gluing treatment devices. The remaining one warp group can be glued by passing through the corresponding gluing processing device, and divided into a plurality of warp sheets by the yarn feeding side warp dividing device. Each warp group of the warp sheet can be pasted through a processing machine.

  In the former case, the pretreatment device located on the downstream side may be deactivated or activated.

  As a result, according to another gluing device, a plurality of warp paths can be appropriately selected according to the number, thickness, type, and the like of the warps to be glued.

  Referring to FIG. 1 and FIG. 2, the gluing device 10 performs pre-processing on a plurality of warps 12 to be processed, then glues, dries the glued warp, and then winds Used as a device for winding around a beam. Each roll described later extends in the width direction of the warp sheet and has a length longer than the width dimension of the warp sheet 34.

  The gluing device 10 includes first and second pretreatment devices 14 and 16 that perform pretreatment, a pretreatment warp dividing device 18 that divides the plurality of warps 12 from the pretreatment device 14 into a plurality of warp groups, First and second sizing apparatuses 20 and 22 for gluing a plurality of warps 12 are included.

  The preprocessing devices 14 and 16 and the pasting processing devices 20 and 22 in the movement direction of the warp 12 are arranged from the upstream side in the first preprocessing device 14, the first pasting processing device 20, and the second preprocessing. The device 16 and the second gluing processing device 22 are provided. The pretreatment warp splitting device 18 is disposed between the first pretreatment device 14 and the first gluing processing device 20.

  The first pretreatment device 14 and the first gluing processing device 20 act as a first processing machine, and the second pretreatment device 16 and the second gluing treatment device 22 act as a second processing machine. To do.

  As shown in FIG. 1, a beam stand 24 is arranged as a yarn feeder on the upstream side in the moving direction of the warp 12 of the gluing device 10. A plurality of warp beams 26 around which the warp yarns 12 are wound are removably supported on the beam stand 24.

  As a yarn feeding device, a creel may be used instead of the warp beam 26. Although not shown, a plurality of warp beam groups each formed by four warp beams 26 are arranged on the beam stand 24.

  The warp yarns 12 extending from each warp beam 26 are wound on the lower side in FIG. 1 of the guide roll 28 arranged on the downstream side of each warp beam group and below the warp beam group, and are directed rightward (downstream side). extend.

  The plurality of warp yarns 12 extending from the plurality of guide rolls 28 extend toward the plurality of guide rolls 30 located on the right side (downstream side) of the guide roll 28 in FIG. The warp sheet 34 is guided to the lower side and arranged in a sheet shape.

  The pretreatment device 14 performs a pretreatment for attaching the pretreatment liquid 36 for pretreatment to the warp sheet 34 and squeezing it. The pretreatment warp splitting device 18 executes a splitting process for splitting the preprocessed warp sheet 34 into a plurality of warp groups. The first and second gluing processing devices 20 and 22 execute a gluing process for gluing the divided warp sheets (warp group) 38 and 40 with the gluing liquids 42 and 44, respectively.

  As the pretreatment liquid 36, a hot paste liquid or water is used. As the paste liquids 42 and 44, liquids having the same paste concentration are used according to the type of warp 12 to be processed. When the pretreatment liquid 36 is a paste liquid, the paste density is selected to be the same as or lower than that of the paste liquids 42 and 44.

  Depending on the type of warp 12 to be processed, when the pretreatment liquid 36 is a paste liquid, the paste concentration can be the same as the concentrations of the paste liquids 42 and 44. By doing so, even if the paste liquid as the pretreatment liquid 36 is conveyed to the paste liquids 42 and 44 for the pasting process by warp, the paste liquids 42 and 44 are not diluted.

  The glued split warp sheets 38 and 40 are subdivided into subdivided warp sheets 48, 50 and 52, 54 between the first and second glue processing devices 20 and 22 and the drying device 46, respectively. And sent to the drying device 46.

  The drying device 46 includes a plurality of preliminary drying cylinders 56, a plurality of guide rolls 58, a plurality of main drying cylinders 60, and the like in order to dry the warp yarns 12 of the subdivided warp sheets 48, 50 and 52, 54 after gluing. I have.

  The re-divided warp sheets 48, 50, 52 and 54 are heated and dried by moving while contacting the surface of the preliminary drying cylinder 56. The subdivided warp sheets 48, 50, 52, 54 that have passed through the preliminary drying cylinder 56 are again integrated into the warp sheet 34 and wound around the surface of the main drying cylinder 60 at the subsequent stage.

  The integrated warp sheet 34 is heated and dried again by moving while contacting the surface of the main drying cylinder 60. The dried warp sheet 34 is wound around a winding beam (not shown) through a guide roll 58, a yarn separating bar (not shown), and a winding guide roll (not shown).

  Each of the pretreatment devices 14 and 16 includes a pretreatment tank 62 that contains the pretreatment liquid 36, an adjustment tank 64 for the pretreatment liquid 36, and a pair of immersion rolls 66 that immerse the warp yarn 12 in the pretreatment liquid 36. 68 and a squeezing roll 70 for squeezing the pretreatment liquid in the pretreated warp yarn.

  The dipping rolls 66 and 68 are arranged so that the dipping roll 66 is positioned upstream of the dipping roll 68 in the moving direction of the warp yarn 12 and a part of the dipping rolls 66 and 68 can be in the pretreatment liquid 36 in the pretreatment tank 62. Has been.

  The squeeze roll 70 is arranged on the upper side of the dip roll 68 so as to squeeze the warp yarn soaked with the pretreatment liquid in cooperation with the dip roll 68. Both the immersion roll 66 and the squeezing roll 70 of the pretreatment devices 14 and 16 can change the positional relationship in the vertical direction with respect to the corresponding immersion roll 68.

  The dipping rolls 66 and 68 are arranged adjacent to each other in the moving direction of the warp sheet 34 (the left-right direction in FIGS. 1 and 2). In the illustrated example, the lower half of the immersion rolls 66 and 68 is immersed in the pretreatment liquid 36.

  In the example shown in FIGS. 1 and 2, the second pretreatment device 16 is in an inoperative state. That is, the dip roll 66 and the squeeze roll 70 of the pretreatment device 16 are displaced upward from the corresponding dip roll 68 and are displaced upward, whereby the second pretreatment device 16 is provided. A travel path of the split warp sheet 40 that reaches from the guide roll 90 to the guide roll 92 provided in the second gluing processing device 22 is formed between the guide roll 90 and the dipping roll 68. Without being immersed in the pretreatment liquid.

  In each pretreatment tank 62, the pretreatment liquid 36 overflowing from the pretreatment tank 62 is collected in the one-end adjustment tank 64. The pretreatment liquid in the adjustment tank 64 is always circulated to the pretreatment tank 62 via a filter (not shown), the pretreatment pump 72 and the pipe 74.

  Impurities in the pretreatment liquid 36 are inclusions such as cotton wax contained in the warp 12 that prevent adhesion of glue, fluff, fluff, etc. Most of such impurities are generated by the warp sheet 34. When passing through the pretreatment device 14, the warp yarn 12 is detached and removed, and enters the pretreatment liquid 36 in the pretreatment tank 62.

  Impurities such as fallout in the pretreatment liquid 36 are carried to the adjustment tank 64 together with the pretreatment liquid 36 overflowing from the pretreatment tank 62. Since the pretreatment liquid 36 in the adjustment tank 64 is constantly circulated through the filter (not shown), the pretreatment pump 72, and the pipe 74, most of the impurities in the pretreatment liquid 36 in the adjustment tank 64 are filtered. To be recovered.

  The warp sheet 34 is wound around the upper side of the guide roll 76, the lower side of the immersion roll 66, the upper side of the immersion roll 68, and the lower side of the squeeze roll 70 in this order. As a result, the pretreatment liquid adheres to the warp yarns of the warp sheet 34. For this reason, the impurities of the pretreatment liquid 36 adhere to the warp together with the pretreatment liquid 36.

  When the warp sheet 34 passes between the dip roll 68 and the squeeze roll 70, the warp sheet 34 is moderately squeezed. As a result, the pretreatment liquid 36 penetrates into the warp yarn 12.

  The dipping roll 68 and the squeezing roll 70 simultaneously apply squeezing action to all the warps of the warp sheet 34. The warp of the warp sheet 34 is before being split by the pretreatment warp splitting device 18, and since the interval between adjacent warps is narrow in a state where the warp is in contact with the outer peripheral surface of the dipping roll 68 and extends, the pretreatment liquid 36 Is effectively squeezed out and the amount accumulated between the adjacent warp yarns 12 is small.

  As a result, the amount of the pretreatment liquid remaining between the warps adheres to the warp 12 that has been squeezed together with the impurities and is carried to the first and second sizing apparatuses 20 and 22 is small. It is possible to suppress contamination with impurities. Further, when the pretreatment liquid 36 is water or a paste liquid having a lower glue concentration than the paste liquids 42 and 44, the amount of the pretreatment liquid 36 carried by the warp to the pasting processing apparatuses 20 and 22 is small. Dilution of the liquids 42 and 44 with the pretreatment liquid 36 is delayed. Therefore, it becomes easy to manage the glue concentration of the glue liquids 42 and 44 of the first and second glue processing apparatuses 20 and 22, and the warp yarn 12 can be easily maintained at a predetermined glue adhesion rate.

  The pretreatment warp splitting device 18 includes split guide rolls 80, 82, and 86 disposed between the preprocessing device 14 and the first and second gluing processing devices 20 and 22 in the moving direction of the warp sheet 34. have. The dividing guide roll 80 guides a part of the preprocessed warp sheet 34 to the first gluing processing device 20, and the dividing guide rolls 82 and 86 are arranged on the upper side and the lower side, respectively. The other part of the pretreated warp sheet 34 is guided to the second gluing processing device 22. As described above, the pretreatment warp splitting device 18 splits the warp sheet 34 into two parts by guiding a part and other parts of the warp sheet 34 to the pasting processing devices 20 and 22, respectively.

  The pretreatment warp splitting device 18 splits the warp yarns 12 of the warp sheets 34 aligned in the width direction into split guide rolls 80 and split guide rolls 82 approximately every other. That is, the warp yarn 12 guided to the dividing guide roll 80 and the warp yarn 12 guided to the dividing guide roll 82 are adjacent to each other in the state of the warp sheet 34.

  The warp yarns of one and the other warp group guided to the split guide rolls 80 and 82 are first and second split warp sheets 38 and 40 having substantially the same width as the warp sheet 34, respectively. Therefore, the warp density in the first and second split warp sheets 38 and 40 is smaller than the warp density in the state of the warp sheet 34.

  In the present embodiment, the first and second gluing processing devices 20 and 22 use the same device, and the front of the same type as the preprocessing device 14 is provided upstream of the second gluing processing device 22. A processing device 16 is arranged.

  The dividing guide roll 80 is disposed on the upstream side of the first gluing processing device 20 and functions as a guide roll for the first gluing processing device 20.

  The second split warp sheet 40 guided to the split guide roll 82 is turned downward by the split guide roll 82 and is below the guide roll 86 disposed below the first gluing processing device 20. The guide is provided on the upper side of the pretreatment device 16 by being hung on the lower side of the first pasting processing device 20 and passing on the lower side of the guide roll 88 provided on the lower side of the pretreatment device 16. It is wound on the upper side of the roll 90 and further extends to the guide roll 92 of the second gluing processing device 22.

  The guide roll 92 of the second gluing processing device 22 has the same shape as the dividing guide roll 80, and the attachment position to the second gluing processing device 22 is the first gluing processing device. It is attached to the second gluing processing device 22 so as to be at the same position as the attachment position of the dividing guide roll 80 to 20.

  The first and second gluing processing apparatuses 20 and 22 store the gluing liquids 42 and 44 in gluing tanks 94 and 96, respectively. The paste liquids 42 and 44 have a paste concentration equal to or higher than that of the paste liquid used as the pretreatment liquid 36. The paste liquids 42 and 44 are the same paste liquid.

  The first and second gluing processing apparatuses 20 and 22 respectively move immersion rolls 98 and 100 extending in the width direction of the split warp sheets 38 and 40 and immersion rolls 102 and 104 to move the split warp sheets 38 and 40, respectively. The paste tanks 94 and 96 are arranged adjacent to each other in the direction.

  On the upper side of the dipping rolls 102 and 104, squeezing rolls 106 and 108 are arranged adjacent to the dipping rolls 102 and 104, respectively.

  Further, the first and second gluing processing apparatuses 20 and 22 respectively divide the immersion rolls 110 and 112 and the squeeze rolls 114 and 116 on the downstream side of the rolls 102, 106 and 104, 108, respectively. The warp sheets 38 and 40 are arranged adjacent to each other in the moving direction. The lower sides of the rolls 98, 102, 110 and 100, 104, 112 are immersed in the paste liquids 42 and 44, respectively.

  The split warp sheets 38 and 40 are respectively provided above the split guide roll 80 and guide roll 92, below the immersion rolls 98 and 100, above the immersion rolls 102 and 104, and below the immersion rolls 110 and 112. It is wound in order.

  The split warp sheets 38 and 40 respectively apply the adhered glue solutions 42 and 44 between the dip rolls 102 and 104 and the squeeze rolls 106 and 108, and between the dip rolls 110 and 112 and the squeeze rolls 114 and 116, respectively. Squeezed out moderately and then headed to the drying device 46.

  Since the split warp sheets 38 and 40 are respectively glued in the first and second glue processing apparatuses 20 and 22 with a wide warp interval, the glue liquid is sufficiently immersed in the glue liquid and sufficiently squeezed. It can penetrate into the inside of the fiber and increase the gluing effect.

  Also, in the drying device 46, the split warp sheets 38 and 40 are dried using the separate pre-drying cylinders 56, so that a sufficient warp interval can be obtained, the drying efficiency is increased, and the warp is increased. Interference between each other can be suppressed. As a result, it is possible to suppress both the opening failure of the loom due to the sticking of the warps to each other, the generation of fluff due to separation of the fixed warp, and the opening failure of the loom due to the exposure of the fluff that has been fluffed by the glue. Can do.

  In the first and second paste tanks 94 and 96, the paste liquids 42 and 44 of the first and second adjustment tanks 118 and 120 are filters (not shown), and the first and second paste tanks, respectively. Circulated constantly through the production pumps 122 and 124 and the pipes 126 and 128.

  The glue liquid overflowing the overflow walls of the first and second paste tanks 94 and 96 is collected in the first and second adjustment tanks 118 and 120.

  Each guide roll can be a driven roll that is rotated by movement of a warp or warp sheet. On the other hand, the immersion rolls 68, 102, 104, 110, and 112 can be drive rolls rotated by drive means. However, the other dipping rolls 66, 98 and 100 and the squeezing rolls 70, 106, 108, 114 and 116 are preferably driven rolls rotated by the contacting rolls.

  Referring to FIG. 3, the gluing device 10 not only forms a warp path as shown in FIGS. 1 and 2, but also processes the warp yarns, and supplies the guide rolls 30, 32, 76, 88, etc. A warp sheet as shown in FIG. 3 may be formed by acting as a yarn feeding side warp splitting device that splits the warp from the yarn.

  When the warp path shown in FIG. 3 is formed, the warp sheet 34 is divided into two warp groups of the first and second split warp sheets 130 and 132 by the guide rolls 30, 32, 76, 88 and the like. The pre-processing device 16 disposed upstream of the pasting processing device 22 is put into an operating state in the same manner as the pre-processing device 14 in order to pre-process the split warp sheet 132.

  The first and second split warp sheets 130 and 132 are pretreated and glued by the first and second pretreatment devices 14 and 16 and the first and second gluing treatment devices 20 and 22, respectively. Attached processing is done.
