Description

The present invention relates to a cloth cleaning apparatus for cleaning a cloth, a carpet, and the like while transporting the cloth .

  When manufacturing a sheet body such as a fabric, it is necessary to wash the chemicals applied in various processing steps or the fluff generated in the processing step in the final step. For example, cleaning of chemicals, pastes, dyeing assistants, unfixed dyes and pigments used in scouring and dyeing processes, and cleaning of dirt such as fiber scraps and fluff is performed.

  As such a fabric cleaning device, a cleaning device for cleaning the fabric in an immersion tank storing a cleaning liquid is used. In such a cleaning apparatus, unfixed dyes, glues, auxiliaries, and the like are discharged from the fabric into the cleaning liquid and dissolved or dispersed. In continuous processing, recontamination from the cleaning liquid to the dough tends to occur. In addition, for the purpose of preventing contamination and promoting the cleaning effect, it is necessary to perform treatments such as using a cleaning agent and raising the temperature of the cleaning solution. Depending on the type of fiber, the agent and the bath temperature must be changed. As cleaning agents, various activators, pH adjusters, reducing agents, and the like, as well as neutralization and rinsing steps are required, and a plurality of cleaning tanks are required, so that the size and complexity of the apparatus cannot be avoided.

In addition to such a cleaning process, a cleaning apparatus has been proposed for cleaning by spraying a cleaning liquid onto the fabric. For example, Patent Document 1 describes that the fabric is washed with washing water overflowed from the shower box while the fabric is guided and transferred to the perforated drum. Further, Patent Document 2 describes that the fabric is washed by spraying a cleaning liquid from a large number of jet tubes arranged in two upper and lower rows while transporting the cloth in the form of a cloth by a perforated conveyor. Patent Document 3 describes that a cleaning liquid ejector is provided on one side of a running fabric and a cleaning liquid suction device is provided on the opposite side so that the cleaning liquid penetrates in the thickness direction of the fabric and is drained. ing. Moreover, in patent document 4, the point which was made to give a jet shower from the some injection nozzle with respect to the fabric introduce | transduced in the processing tank is described.

  In the above-described prior art, the cleaning liquid can be applied to the entire fabric by spraying. However, when the cleaning liquid is sprayed in a state where the fabric is slackened, a portion where the sprayed cleaning liquid hits and a portion where the sprayed cleaning liquid does not hit are generated. It becomes difficult.

  In addition, even when the fabric is not slackened, if there is a portion where the cleaning solution hits and a portion where the cleaning liquid does not hit, wrinkles are generated at the boundary portion, and the fabric is locally slackened at the wrinkles, and the cleaning effect Decreases.

  When the cloth is washed while being supported by the perforated drum as in Patent Document 1, the cloth in the through-hole portion is easily vibrated by the spraying action, and the kinetic energy of the cleaning liquid sprayed on the cloth is reduced by the vibration. Thus, a sufficient cleaning effect cannot be obtained.

Accordingly, the present invention is an object to provide a fabric cleaning apparatus of the kinetic energy of the cleaning liquid to be injected can be made to contribute efficiently to the cleaning action of the fabric.

Fabric cleaning apparatus according to the present invention is a fabric cleaning apparatus for cleaning while conveying the cloth, to inject a support portion for supporting the support surface fabric to be conveyed, the cleaning solution to the water curtain with respect to the support part injection A support roll for supporting the fabric in close contact with a peripheral surface, a pair of guide rolls disposed above the support roll, and the support roll and the guide roll. And a pair of tension rolls arranged at a smaller interval than the outer diameter of the support roll, and the fabric is guided downward toward the support roll by one of the guide rolls. After being wound around the peripheral surface of the support roll, it is guided upward toward the other guide roll and wound around the support roll by the tension roll. It is set so as to be fed with tension so as to be attached, and the spray unit is disposed below the support roll and is set to spray the cleaning liquid upward toward the support roll. cage, washing region of the support surface which acts the injection pressure of the cleaning liquid is supported in a state where one entire side of the fabric at least the washing zone is in close contact with the support surface while being formed across the entire width of the fabric It is characterized by that. Furthermore, the support roll is driven to rotate at the same peripheral speed as the transport speed of the fabric . Furthermore, the injection unit includes a plurality of injection nozzles arranged along the cleaning region.

By having the configuration as described above, cleaning is performed by injecting the cleaning liquid in the form of a water curtain in a state where the entire one side of the fabric is in close contact with the support surface in the cleaning region. This can contribute to the cleaning action of the fabric .

That is, since the entire one surface side of the fabric is in close contact with the support surface, there is no gap between the fabric and the support surface, and the vibration of the fabric due to the spraying action of the cleaning liquid is suppressed, and the cleaning liquid Kinetic energy contributes to the cleaning action. In general, in the case of cleaning by spraying, it is preferable that the cleaning liquid flows vigorously with respect to the fabric , so that the stains such as the drug are easily cleaned. For this purpose, it is preferable that the cloth does not move with respect to the cleaning liquid. In the present invention, it is possible to enhance the cleaning effect of the cleaning liquid by setting the cloth so that it does not move as much as possible in close contact with the support surface.

In addition, since the cleaning area of the support surface is formed over the entire width of the fabric and the cleaning liquid is sprayed in the form of a water curtain, the cleaning liquid can be uniformly applied over the entire width of the fabric , and generation of wrinkles due to spraying can be prevented. For this reason, it is possible to suppress a decrease in cleaning effect due to generation of wrinkles.

Then, as a support, by using the supporting roller for supporting in close contact with the fabric on the circumferential surface, the fabric can be washed successively while conveying the support rolls, it is possible to perform efficient cleaning. In addition, if the support roll is rotationally driven at the same peripheral speed as the cloth conveyance speed, the cloth can be conveyed without slackening, and the cloth can be washed in a state of being in close contact with the support surface of the support roll. It becomes.

  Further, by using a plurality of spray nozzles arranged along the cleaning region as the spray section, the spray liquid can be formed in a water curtain shape while spraying the cleaning liquid at a high pressure.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is a schematic configuration diagram relating to an embodiment of the present invention. The fabric cleaning apparatus 1 that cleans a fabric that is a sheet body includes a carry-in unit 10 that transports the loaded fabric F, three cleaning units 11 to 13, and a carry-out unit 14. The fabric F to be carried in is expanded in the width direction by the spreading roll 30 and is carried into the fabric washing apparatus 1 by the transport roller group 31. In addition, the fabric F carried out from the fabric cleaning device 1 is transported to the next step by the transport roller group 40.

  The carry-in unit 10 conveys the fabric F at a predetermined conveyance speed by the drive roll 10 a and carries it into the cleaning unit 11.

  FIG. 2 is a schematic configuration diagram relating to the cleaning unit 11. The cleaning unit 11 includes a support roll 11a and guide rolls 11b and 11c, and the fabric F is guided toward the lower support roll 11a by the guide roll 11b. The fabric F is wound around the peripheral surface of the support roll 11a and then guided toward the upper guide roll 11c, and is guided to the next cleaning unit 12 by the guide roll 11c.

  A tension roller 11d is disposed between the support roll 11a and the guide roll 11b, and a tension roller 11e is disposed between the support roll 11a and the guide roll 11c, and the fabric F is tensioned by the tension rollers 11d and 11e. Is provided, and the fabric F can be wound around the peripheral surface of the support roll 11a by a predetermined length and conveyed in a stable state. And the fabric F comes to be supported in the state which the one surface side closely_contact | adhered without the clearance gap to the surrounding surface which is the support surface of the support roll 11a.

  The support roll 11a is rotationally driven at the same peripheral speed as the transport speed of the fabric F, and the fabric F stably carries out continuous transport in a state of being in close contact with the peripheral surface of the support roll 11a. be able to.

  The support roll 11a preferably has a smooth surface with a hard peripheral surface. For example, a metal roll made of a smooth surface can be used. And the unevenness | corrugation, a hole, etc. are not formed in the surrounding surface of the support roll 11a, but it is set so that a space | gap may not be formed in the state closely_contact | adhered with the fabric F. FIG.

  The cleaning unit 11 includes an injection unit 21 below the support roll 11a, and the injection unit 21 includes a plurality of injection nozzles 21a that inject cleaning liquid upward on the upper surface of the main body 21b. FIG. 3 is a schematic view of the injection unit 21 as viewed from a direction orthogonal to the axial direction of the support roll 11a. FIG. 4 is a partially enlarged perspective view of the support roll 11a and the injection unit 21.

  Inside the main body 21b, a supply pipe (not shown) is disposed over the entire length, and each injection nozzle 21a is attached to a plurality of branch pipes connected to the supply pipe. Then, when the supply pipe is connected to a cleaning liquid supply device (not shown) and the cleaning liquid is pumped to the supply pipe, the cleaning liquid is ejected from the injection nozzles 21a all at once.

  The plurality of injection nozzles 21a are arranged at equal intervals over the entire length along the axial direction of the support roll 11a. As shown by the dotted lines in FIGS. 2 and 3, the cleaning liquid sprayed from the spray nozzle 21a is sprayed at a predetermined spray angle so as to spread in a fan shape in the axial direction of the support roll 11a, and in a direction perpendicular to the axial direction. Is ejected flat with a predetermined width that is slightly larger than the nozzle diameter.

  Therefore, the spray region where the cleaning liquid sprayed from the spray nozzle 21a hits the surface of the support roll 11a is formed in an elongated strip shape having a predetermined length along the axial direction of the support roll 11a. And since the injection area | region of the adjacent injection nozzle 21a is set so that the both ends of the axial direction of the support roll 11a may overlap, the washing | cleaning area | region R which becomes the whole injection area | region of all the injection nozzles 21a is a support roll. 11a is set in a strip shape having a predetermined width in the circumferential direction and extending over the entire width along the axial direction of 11a. In the cleaning region R set in this way, the entire one surface side of the fabric F is in close contact with the support surface of the support roll 11a.

  As described above, the shape of the jets ejected from each of the ejection nozzles 21a is fan-shaped and flat, and the jets of the adjacent ejection nozzles are overlapped with both ends. It is formed in a water curtain shape along the axial direction of the support roll 11a. In the portion where the jets overlap, the jets intersect each other but are jetted toward the support roll 11a, so that they are not greatly reduced, and the jetting pressure applied to the surface of the support roll 11a is almost uniform over the entire cleaning region R. Become.

  In order to form such a water curtain-like jet W, for example, the spray angle of each spray nozzle 21a is set to 20 degrees to 40 degrees, the array interval is set to 40 mm to 60 mm, and the distance to the support roll 11a is set to 80 mm to 150 mm. It is good to set to.

  What is necessary is just to set the injection pressure from the injection nozzle 21a according to the kind of sheet | seat body to wash | clean, and the grade of dirt, for example, it is preferable to set to the range of 0.5 MPa-7.0 MPa. Moreover, the angle of the injection direction on the support surface is preferably set to 85 degrees to 95 degrees.

  In this way, the water curtain-like jet W is jetted from the jet section in a direction substantially perpendicular to the support surface, and jets almost uniformly over the entire width of the fabric F supported in close contact with the support surface. Pressure is applied and the fabric F does not wrinkle. Further, since no gap is formed between the fabric F and the support surface, the fabric does not vibrate due to the jetting pressure, and the kinetic energy of the jetted cleaning liquid is washed without being reduced by the vibration of the fabric. Will contribute to the action. In addition, since the cleaning liquid used for the cleaning process of the fabric F falls down as it is, the cleaned dirt or the like hardly remains in the fabric F, and the dirt or the like can be surely washed off. Therefore, in the cleaning region R of the support surface, the cleaning process of the fabric F can be performed efficiently, and an effective cleaning process can be performed in a short time when the continuously conveyed fabric F passes.

  In the present embodiment, the fabric F cleaned in the cleaning unit 11 is subjected to the same cleaning process in the cleaning units 12 and 13. The cleaning unit 12 includes a support roll 12a, guide rolls 12b and 12c, tension rollers 12d and 12e, and an injection unit 22. The cleaning unit 13 includes a support roll 13a, guide rolls 13b and 13c, and tension rollers 13d and 13e. In addition, as in the cleaning unit 11, the fabric F that is in close contact with the support roll is cleaned by a water curtain-like jet.

  By repeating the washing process three times in this way, dirt and the like can be completely washed away. What is necessary is just to set the number of the washing | cleaning parts to install by the grade of the stain | pollution | contamination etc. of the sheet | seat body to wash | clean. As described above, since the cleaning unit has a simple structure and is compact, it can be easily added.

In the example described above, the support roll is used for the support portion of the fabric . However, in the case of a low flexibility fabric such as a carpet, a bed-type support member may be used to closely contact the back side of the fabric. .

The fabric cleaning device according to the present invention is suitable as a cleaning device for a sheet body that has flexibility such as fabric, film, leather, and carpet and is easily vibrated by spraying the cleaning liquid.

It is a schematic block diagram regarding embodiment which concerns on this invention. It is a schematic block diagram regarding a washing | cleaning part. It is the schematic which looked at the injection part from the direction orthogonal to the axial direction of a support roll. It is a partially expanded perspective view regarding a support roll and an injection part.
