Japanese Patent Publication No. 7-91778 Japanese Patent Laid-Open No. 9-201503

The warp gluing machine disclosed in Patent Document 1 has the following problems.
(1) The paste S for gluing the warp sheet W is used at a high temperature of 90 to 95 ° C. For this reason, the paste component in the paste liquid is easily dried and fixed, and the filter 14 is clogged and the drive unit of the rotary drum 12 is likely to fail. Even if the sealing structure with the lid 34 is adopted, it is difficult to prevent the glue component from drying and sticking after the operation of the warp gluing machine is completed. Therefore, at the end of the operation of the warp gluing machine, complicated and large-scale cleaning of the components of the rotary drum 12 and the drive part of the rotary drum 12 including the filter 14 must be sufficiently performed.

(2) Since foreign matter adheres to the filter 14 after passing through the filtration position of the paste S supplied from the paste liquid tank 1 into the auxiliary tank 8, the foreign matter is scraped off by the brush roller 26. Yes. However, since the paste liquid S is in a high-temperature state as described above, the brush is deteriorated by heat, and further, the adhesive component adheres to the brush and becomes wrinkled and the foreign matter scraping function is deteriorated at an early stage.

(3) Even if the filter 14 made of woven wire mesh is formed in a cylindrical shape, its rigidity is weak as it is, and it cannot withstand the pressing force of the brush roller 26, so it is wound around a reinforcing cylinder having a large number of small holes. ing. The small holes formed in the reinforcing cylinder must be formed with a significantly smaller space ratio than the filter 14 in order to increase the rigidity. For this reason, in order to give sufficient processing capability to the amount of the paste liquid S flowing into the auxiliary tank 8, the surface area of the filter 14 including the reinforcing cylinder must be sufficiently increased. Therefore, since the entire filtering device is increased in size and weight, the driving device for the filter 14 must have a high output.

  The sewage treatment machine disclosed in Patent Document 2 discharges water to the mesh drum 2 using the filtered purified water stored in the water purification chamber 16, and separates and removes filth adhering to the inner peripheral surface of the mesh drum 2. . Therefore, when the sewage treatment machine of Patent Document 2 is used as a paste liquid filtering device of a warp gluing machine, since a brush is not required, the problem (2) of Patent Document 1 and a filter for removing foreign matter by water discharge Since the strength is not so much required, it can be expected that the problem (3) of Patent Document 1 will be solved to some extent.

  However, the paste used in the warp pasting machine must be maintained at a constant high temperature as described above, and the paste concentration must be maintained in a preset state. Therefore, if the configuration of the sewage treatment machine disclosed in Patent Document 2 is used as it is for the paste liquid filtering device of the warp glue applicator, the following problems arise.

  A part of the washing water discharged to the surface of the mesh drum 2 is transferred to the outer peripheral surface of the mesh drum 2 and falls in a large amount into the water purification chamber 16. There is no problem because the water is the same in the sewage treatment machine. However, in the paste liquid filtration device, what is stored in the auxiliary tank corresponding to the water purification chamber 16 is not the wash water but the paste liquid that is reused for gluing the warp sheet. If it mixes with, it will affect the fall of paste liquid density | concentration and paste liquid temperature directly.

  An object of the present invention is to clean the filter so as not to affect the paste liquid after filtration.

  The present invention according to claim 1 is provided with a paste liquid tank for adhering the paste liquid to the warp sheet and an auxiliary tank for receiving the paste liquid flowing out of the paste liquid tank, and a cylinder having a cylindrical filter in the auxiliary tank. A mold filter is disposed in a horizontal direction so as to be rotatable, and the paste liquid flowing out from the paste liquid tank is circulated inside and outside the cylindrical filter to be filtered and the filtered paste liquid is stored in the auxiliary tank. In the constructed warp gluing machine, a steam injection member is disposed opposite the cleaning position after passing through the filtration position on the filter surface on the side from which the paste liquid of the filter after flowing through the filtration position flows out, A foreign matter receiving tray is arranged toward the filter surface on the side into which the paste liquid flows so as to face the steam injection member. In the present invention, the “filtration position” refers to the position where the paste liquid flows through the cylindrical filter for filtration, and the “washing position” refers to the rotational direction of the cylindrical filter rather than the “filtration position”. It is the downstream side when viewed, and refers to a position where the paste liquid does not flow for filtration on the filter surface of the cylindrical filter.

  According to the present invention of claim 1, since the means for separating the foreign matter adhering to the filter is steam, there is no mixing of moisture into the paste liquid after filtration, which affects the concentration and temperature of the paste liquid. No.

  According to a second aspect of the present invention, the paste liquid flowing out from the paste liquid tank is supplied to the inside of the cylindrical filter, and a vapor injection member is disposed on the outside of the cylindrical filter and the foreign matter receiving tray. Is disposed inside the cylindrical filter, so that the most practical configuration can be obtained as a paste liquid filtering device.

  According to a third aspect of the present invention, the steam injection member is connected to a steam supply means to the heating pipe for the paste liquid provided in the auxiliary tank. In addition, since the temperature in the paste liquid filtering device can be appropriately maintained, the paste liquid temperature after filtration is not affected.

  The present invention according to claim 4 is characterized in that a cover for sealing the cylindrical filter and the vapor injection member is provided in the auxiliary tank so as to be openable and closable. It is possible to prevent leakage and to prevent a temperature drop in the paste liquid filtering device.

  According to the fifth aspect of the present invention, a cleaning water discharge nozzle for washing out foreign matter is disposed on one end side of the foreign matter receiving tray, and the other end side of the foreign matter receiving tray is disposed outside the auxiliary tank. Since it is connected to a dust receptacle that separates the cleaning water and the foreign matter, the foreign matter that accumulates on the foreign matter receiving tray can be washed away and discharged out of the foreign matter receiving tray with a simple configuration.

  The present invention according to claim 6 is characterized in that the steam injection member injects steam intermittently, so that the power for supplying steam and the amount of use of steam can be reduced. Energy saving of the filtration device can be promoted.

  The present invention can appropriately perform the cleaning of the filter without affecting the paste liquid in the paste liquid filtering device of the warp pasting machine.

(First embodiment)
Hereinafter, the first embodiment will be described with reference to FIGS. 1 and 2.
The pasting device 1 of the warp pasting machine generally includes a pasting tank 2 for storing a pasting liquid S in which a pasting agent such as starch or polyvinyl alcohol is dissolved in a solvent water, and the rear part of the pasting liquid tank 2 (FIG. 2). The immersion roller 3 disposed in a state of being half-immersed in the paste liquid S on the left side), and disposed in a state of being half-immersed in the paste liquid S on the front portion (right side in FIG. 2) of the paste liquid tank 2. The lower glue squeezing roller 4 and the upper glue squeezing roller 5 placed on the lower glue squeezing roller 4 are configured.

  A warp sheet W in which a large number of spun yarns are juxtaposed passes through the adhesive solution S in the adhesive solution tank 2 through the lower position of the immersion roller 3, and then between the lower adhesive squeezing roller 4 and the upper adhesive squeezing roller 5. The paste liquid S is adhered by passing through the. The glued warp sheet W is transferred in the direction of the arrow, and is dried in a drying step (not shown) including a drying cylinder or the like as a subsequent step. The paste liquid tank 2 is provided with a plurality of (two in the figure) heating pipes 6 for jetting high-temperature steam into the paste liquid S, and the paste liquid S is supplied by the steam jetted from each heating pipe 6. It is configured to heat and maintain in a temperature range of approximately 90-95 ° C. The outflow part 7 is provided in the rear side wall of the paste liquid tank 2, and the paste liquid S in the paste liquid tank 2 is continuously or periodically discharged to keep the paste liquid surface at a constant height.

  An auxiliary tank 8 for the paste liquid S is provided on a machine stand (not shown) provided at the lower rear position of the paste liquid tank 2. The outflow pipe 9 connected to the outflow part 7 of the paste liquid tank 2 extends to the auxiliary tank 8 side, and the paste liquid receiving part 10 provided in the auxiliary tank 8 with the paste liquid S flowing out from the outflow part 7 of the paste liquid tank 2. It is allowed to flow into. Between the auxiliary tank 8 and the paste liquid tank 2, a paste liquid reflux pipe 12 having a pump 11 is disposed. Accordingly, the paste liquid S is circulated between the paste liquid tank 2 and the auxiliary tank 8 through the reflux pipe 12 by the operation of the pump 11.

  In addition, a plurality of (three in the figure) heating pipes 13 for ejecting high-temperature water vapor into the paste liquid S are provided at the lower portion of the auxiliary tank 8, and each is connected to a steam supply source 14. The steam supply source 14 is also connected to a heating pipe 6 installed in the paste liquid tank 2. In the case of this embodiment, the steam supply source 14 shares the steam supply source used in the above-described drying process. The water vapor ejected from each heating pipe 13 heats the paste liquid S in the auxiliary tank 8, and is configured to be maintained in a temperature range of approximately 90 to 95 ° C. as in the paste liquid tank 2.

  A paste liquid filtering device 15 is disposed in the auxiliary tank 8. The paste liquid filtering device 15 has a cylindrical filter 16 disposed above the paste liquid surface of the auxiliary tub 8 so as to be laterally arranged in the width direction of the warp pasting machine. The cylindrical filter 16 is formed by pleating a filter 17 made of a wire net, a resin net, a nonwoven fabric, or the like, the pleated filter 17 is formed in a cylindrical shape, and ring-shaped flanges 18 and 18 are attached to both ends thereof. And the flanges 18 and 18 are screwed to the side rings 19 and 19, respectively. A plurality of connecting rods 20 are passed through the outer peripheral sides of the left and right flanges 18 and 18 to prevent the tubular filter 16 from being deformed.

  The cylindrical filter 16 is disposed between the side plates 21, 21 erected on the auxiliary tank 8, and the support rollers 22 are attached to the side plates 21, 21 at two locations in the front-rear direction (left-right direction in FIG. 2). , 22 are rotatably supported. A ring-shaped large gear 23 is integrally attached to the peripheral surface of the cylindrical filter 16. A bracket 25 to which a motor 24 is attached is fixed to the outer surface of the side plate 21 close to the large gear 23. The drive shaft 26 of the motor 24 is disposed through the side plate 21, and a small gear 27 fixed to the tip thereof meshes with the large gear 23. Accordingly, the cylindrical filter 16 is rotated in the direction of the arrow in FIG. 2 through the small gear 27 and the large gear 23 by the rotation of the motor 24.

  The paste receiving part 10 for the paste S flowing out from the paste tank 2 and supplied by the outflow pipe 9 passes through the inside of the flange 18 and the side ring 19 and opens inside the cylindrical filter 16. Accordingly, the glue liquid S supplied from the glue liquid receiving part 10 to the inside of the cylindrical filter 16 penetrates the filter 17 from the filter inner surface 17a on the side into which the glue liquid S flows, and the side from which the glue liquid S flows out. It drip in the auxiliary tank 8 from the filter outer surface 17b. When the filter 17 penetrates, the paste liquid S is filtered, and foreign matters such as fuzz of warp yarns, foreign matters and paste paste are left on the filter inner surface 17a side. Note that, when the warp sheet W is consumed by the pasting of the warp sheet W and the amount of the paste liquid S in the auxiliary tank 8 is reduced by a certain amount, a new paste liquid S is supplied to the paste liquid receiving part 10 from the paste liquid supply pipe 28.

  Passes through the filtration position of the paste S supplied from the paste receiver 10 (in this embodiment, the position where the post-filtration paste S is dropped from the tubular filter 16 as shown in FIG. 2). Steam injection members 29 and 30 are arranged at two locations above the cylindrical filter 16 so as to face the outer peripheral side of the filter 17 at the cleaning position, that is, the filter outer surface 17b. The steam injection members 29 and 30 are configured by pipes extending in the longitudinal direction of the cylindrical filter 16, and a large number of small holes 31 and 32 are opened toward the filter outer surface 17 b in each pipe. Steam is constantly ejected. The steam injection members 29 and 30 are connected to the steam supply source 14 of the heating pipes 6 and 13 by a steam supply pipe 34 with an on-off valve 33 interposed. The steam supply to the steam injection members 29 and 30 may be performed by installing a dedicated steam supply source.

  The steam ejected from the small holes 31 and 32 of the steam ejecting members 29 and 30 can pass through the filter 17 and blow off foreign matter adhering to the filter inner surface 17a. The small holes 31 and 32 are also provided at positions facing the side rings 19 and 19 on both sides of the cylindrical filter 16.

  On the other hand, a foreign matter receiving tray 35 opened toward the filter inner surface 17a is disposed inside the cylindrical filter 16 so as to face the vapor injection members 29 and 30. As shown in FIG. 1, the foreign matter receiving tray 35 is formed in a box shape having a length that covers the entire length direction of the cylindrical filter 16, and one end 35a is fixed to the left side plate 21 in FIG. The other end 35b penetrates the right side plate 21 in FIG. 1 and is held by the side plate 21 in a state of protruding outward. Further, two water discharge nozzles 36, 36 are opened on the side wall of the one end 35a. Further, the foreign matter receiving tray 35 has at least a bottom wall inclined from the one end 35a side toward the other end 35b side. Accordingly, the foreign matter that has fallen on the foreign matter receiving tray 35 due to the cleaning of the filter 17 is pushed away toward the other end 35 b by the washing water discharged from the water discharge nozzles 36, 36. The foreign matter receiving tray 35 may have a configuration in which the box itself constituting the foreign matter receiving tray 35 is inclined so that the other end 35b side is positioned downward, without tilting the bottom wall thereof.

  A cover 37 that covers the paste liquid filtering device 15 is disposed on the auxiliary tank 8. The cover 37 is attached to the upper part of the auxiliary tub 8 by a hinge (not shown) at the rear side (left side in FIG. 2) of the warp gluing machine, and is provided so as to be opened and closed as indicated by a virtual line in FIG. When the cover 37 is closed, the entire paste liquid filtering device 15 together with the side plates 21 can be sealed in the auxiliary tank 8. Therefore, during the operation of the warp gluing machine, the leakage of the steam injected from the steam injection members 29 and 30 is prevented, and the temperature in the auxiliary tank 8 can be kept in a necessary range.

  Outside the auxiliary tank 8, a washing water tank 38 and a dust catch 39 attached to the inside of the washing water tank 38 are installed. A discharge pipe 40 connected to the other end 35b of the foreign material receiving tray 35 is opened in the dust receiving box 39, and the cleaning water containing the foreign material is discharged. The foreign matter F is separated by the filtering action of the dust catcher 39 and only the filtered cleaning water is stored in the cleaning water tank 38.

  A drain 41 is provided below the washing water tank 38, and the drain 41 is connected to the water discharge nozzles 36 and 36 by a washing water supply pipe 44 with a pump 42 and an on-off valve 43 interposed therebetween. Accordingly, the wash water stored in the wash water tank 38 is pumped up by the operation of the pump 42 and discharged from the water discharge nozzles 36 and 36 by the opening operation of the on-off valve 43, so that the wash water can be reused.

The operation of the first embodiment configured as described above will be described below.
When the warp gluing machine is operated, the warp sheet W circulates around the dipping roller 3 and is adhered with the glue liquid S, and is sandwiched between the lower glue squeezing roller 4 and the upper glue squeezing roller 5 and excess glue liquid S. After being removed, it is transferred to a drying process indicated by the arrow direction.

  The paste S flowing out from the paste tank 2 is sent to the paste receiving part 10 through the outflow pipe 9, and is operated in the direction of the arrow in FIG. 2 by the operation of the paste filtering device 15 closed by the cover 37 (see the solid line in FIG. 2). Is supplied into the rotating cylindrical filter 16. Since the filter 17 is pleated, the effective area for performing the filtering action is large, and the paste liquid S can be efficiently filtered. Since the paste liquid S is filtered by penetrating from the filter inner surface 17a of the filter 17 to the filter outer surface 17b, foreign matter remains on the filter inner surface 17a, and only the filtered paste liquid S is dropped into the auxiliary tank 8 and stored. Is done.

  As the cylindrical filter 16 rotates, the foreign matter passes through the filtering position of the paste liquid S while being adhered and held on the filter inner surface 17a, and is carried to the upper position in FIG. Since the steam sprayed from the steam spraying members 29 and 30 disposed at two symmetrical positions on the top of the cylindrical filter 16 is blown to the filter outer surface 17b, the steam passes through the filter 17 and passes through the filter inner surface. The foreign matter held by 17a is surely blown off to the foreign matter receiving tray 35.

  The foreign matter that has fallen on the foreign matter receiving tray 35 is pushed away to the other end 35 b side by the washing water discharged from the water discharge nozzles 36, 36 and is discharged from the discharge pipe 40 into the dust receiving box 39. The cleaning water is separated from the foreign matter F in the dust receiving bowl 39, and only the cleaning water is dropped into the cleaning water tank 38 and stored. The washing water stored in the washing water tank 38 is supplied to the water discharge nozzles 36 and 36 from the washing water supply pipe 44 through the on-off valve 43 by the operation of the pump 42 and reused.

  When the operation of the warp gluing machine is stopped, it is necessary to open the cover 37 and clean the glue liquid filtering device 15. However, since the filter 17 is always washed during the operation, the glue is used. There is little adhesion state of the liquid S, and it can fully cope with simple cleaning.

In the first embodiment of the present invention described above, the following operational effects are obtained.
(1) Since the filter 17 is constantly washed during the operation of the warp gluing machine, even if the cleaning at the end of the operation is simplified, the filter 17 is not clogged due to adhesion of the glue component. Since no mechanical means like a conventional brush is required, there is no reduction in cleaning ability.
(2) Since the filter 17 is pleated, the filtered foreign matter is reliably held and can be transported to the cleaning position. Further, since the filter 17 is cleaned by steam, there is no possibility that a large amount of water flows down the filter outer surface 17b, and the concentration and temperature of the paste liquid S in the auxiliary tank 8 are not affected.
(3) The filter 17 has high rigidity due to pleating, and it is not necessary to load a means for increasing the strength as in the conventional filter. Further, since the cleaning is performed only by spraying steam, a large force is applied to the filter 17. There is nothing. Therefore, since the frame member etc. which support the filter 17 can be reduced in weight, the paste liquid filtering device 15 can be reduced in size and weight, and the drive device can also be implemented with a small output motor.

(4) Since the steam supply to the steam injection members 29 and 30 shares the steam supply source 14 for heating the paste liquid S, it is not necessary to newly install a special high-temperature steam generator.
(5) Since the cleaning water supplied to the water discharge nozzle 36 is filtered by the dust receptacle 39 and the cleaning water stored in the cleaning water tank 38 is circulated and reused, it is extremely economical.
(6) Since the paste liquid filtration device 15 is closed by the cover 37 during operation, the steam injected from the steam injection members 29 and 30 does not leak to the outside, and the temperature in the auxiliary tank 8 is kept within a predetermined range. Easy to maintain within.
(7) Cleaning after the operation of the warp pasting machine is facilitated because the cylindrical filter 16 is automatically cleaned by operating only the paste filter 15.

(Second Embodiment)
The second embodiment shown in FIG. 3 is obtained by changing the filter 17 in the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The filter 45 shown in the second embodiment is formed by forming a metal net or a resin net of a type that is not subjected to pleating processing into a cylindrical shape, and, similarly to the first embodiment, both ends of the cylindrical filter 45 are connected to the flange 18, 18 and the cylindrical filter 46 is configured by screwing the flanges 18 and 18 to the side rings 19 and 19 respectively. The filtering action of the paste S and the cleaning function of the filter 45 by the vapor injection members 29 and 30 in the second embodiment are the same as those in the first embodiment. Further, the force applied to the filter 45 is only due to the steam injected from the steam injection members 29 and 30. Therefore, since a special cylinder for reinforcing the filter 45 is not required as in the prior art, the effective area of the filter 45 necessary for the filtering action is large, and the filtering action of the paste S can be performed efficiently.

  The present invention is not limited to the configuration of each of the embodiments described above, and various modifications are possible within the scope of the gist of the present invention, and can be implemented as follows.

(1) The lower portions of the filters 17 and 45 are arranged above the adhesive liquid S surface of the auxiliary tank 8 so as not to be immersed, but the adhesive liquid S to be filtered in the filters 17 and 45 is not The lower surfaces of the filters 17 and 45 may be disposed in the state where the lower surfaces of the filters 17 and 45 are immersed in the paste liquid S of the auxiliary tank 8 as long as the inner ring position of the side ring 19 does not overflow.
(2) The steam injection members 29 and 30 may be configured to intermittently inject steam by periodically opening and closing the on-off valve 33 interposed in the steam supply pipe 34. Thereby, the power for supplying steam and the amount of steam used can be reduced, and energy saving of the paste liquid filtering device 15 can be promoted.
(3) In the first and second embodiments, the steam injection member 30 may be omitted, and the cleaning may be performed with only one steam injection member 29. Moreover, you may comprise so that a vapor | steam injection member may be arrange | positioned in three or more places.
(4) The support roller 22 may be provided on a single shaft that is passed between the side plates 21, 21.

(5) The drain 41 may be configured to drain to a predetermined location, and a dedicated cleaning water supply device may be provided to the water discharge nozzle 36 so that new cleaning water is always supplied.
(6) The steam injection members 29 and 30 in the first embodiment are disposed inside the filter 17, the foreign material receiving tray 35 is disposed outside the filter 17, and the outflow pipe 9 connected to the paste liquid tank 2. Can be directly opened in the auxiliary tank 8 and the lower portion of the filter 17 can be immersed in the paste liquid S of the auxiliary tank 8. In this embodiment, since the paste liquid permeates from the outside to the inside of the filter, the outer filter surface becomes the inflow side filter surface, and the inner filter surface becomes the outflow side filter surface. Accordingly, the foreign matter separated from the paste is deposited on the outer filter surface, and then the outer filter surface is cleaned by the steam sprayed from the inside of the filter by the steam jetting member, and the foreign matter is put on the foreign matter receiving tray outside the filter. Blown off. In the case of this embodiment, it is preferable that the steam injection member and the foreign matter receiving tray are arranged in the lateral direction rather than above the filter.

It is the front view which showed a part of warp gluing machine in the cross section. It is the sectional view on the AA line of FIG. It is sectional drawing which shows 2nd Embodiment.
