For example, it is preferable to hermetically package a curtain in a clean state in a resin bag made of vinyl, polyethylene, or the like. From the cleaning process to the completion of the packing process, it is preferable that automation is performed by, for example, a machine so that bacteria, dust, and the like are not reattached to the curtain and the curtain is recontaminated. It is preferable that at least the operator does not touch the curtain after the cleaning process with bare hands. In addition, the curtain after being hermetically packed in a resin bag is no longer recontaminated and can be handled in a clean state (that is, excellent in handleability), and can be packed as usual by an operator. .

《Drug application process》
Even if a clean curtain is provided to the user, if the hermetic package is opened and used, bacteria floating in the room or harmful organic compounds may adhere to the curtain. Therefore, it is preferable that the manufacturing method of the present invention further includes a drug application step of attaching a drug that exhibits an antibacterial action or an organic compound decomposition action to the curtain before the packing process. Specifically, the drug application process includes, for example, a drug spraying process for spraying a drug on the curtain, a heating process for heating the curtain after the drug spraying process and fixing the drug on the curtain (or drying the drug), Preferably it consists of. Of course, when the drug spraying step is performed, it is preferable that the drug is in a state suitable for spraying, specifically, a liquid in which the main component is mixed with a solvent or a dispersion medium.

  Various kinds of such agents are conceivable. For example, a photocatalyst that is safe and excellent in durability is preferable. Examples of the photocatalyst include titanium oxide and tungsten oxide. Any of them may be used, but tungsten oxide that works satisfactorily even at a room light level is more preferable for the curtain.

<Molding process>
The curtain is usually formed into a wave shape (pleating or pleating) in many cases. In many cases, the molding process is performed by heating the fabric after sewing. Therefore, it is efficient to combine the above-described heating process with such a thermoforming process. That is, it is preferable that the heating process described above is a thermoforming process in which the curtain is heated to form a wave shape.

  The heat forming step can be performed, for example, by heating and cooling while sandwiching the curtain between the forming tube rows (heat transfer tube rows) alternately arranged opposite to each other. Heating by each forming tube can be performed by supplying a high-temperature heat medium (such as high-temperature gas containing steam) to the inside thereof. Further, the cooling by each forming tube can be performed by supplying a low-temperature heat medium (cooling water or the like) to the inside thereof.

《Dust-proof environment》
The space for performing the cleaning process and the like according to the present invention is often provided in a curtain sewing factory. In such a case, in order to pack the curtain while maintaining the clean state, it is desired that at least each process from the cleaning process to the packing process is performed in a clean environment (a space such as a clean room). Such an environment can be formed, for example, by surrounding a space for performing each process with a dust-proof wall or a dust-proof sheet. Specifically, after performing the hanging process of hanging the curtain after sewing on the rail before the cleaning process, a series of dust-proof environmental spaces formed with dust-proof walls or dust-proof sheets, or dust-proof walls or dust-proof sheets It is preferable that each process is performed in a dustproof environment station that is divided into compartments. In addition, by providing a suspension process, the movement of the curtain between each process (between each station) can be easily and efficiently performed along the rail.

  Embodiments relating to a curtain fold processing apparatus capable of implementing the curtain manufacturing method of the present invention will be described below with reference to the drawings.

<< First Example >>
(1) Folding Device A curtain fold processing device 1 according to the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the pleat processing apparatus 1 mainly includes a first heat transfer tube array 10, a second heat transfer tube array 20, a heat transfer tube array moving means 30, a heating medium inflow means 40, and a cooling medium inflow means. 50.

  In the first heat transfer tube row 10, a first heat transfer tube 11 (hereinafter simply referred to as “heat transfer tube 11”) whose axis is in the vertical direction is disposed while maintaining a predetermined gap. For the sake of convenience, FIG. 1 shows a case where five heat transfer tubes 11 are arranged, but the number is appropriately adjusted according to the width of the curtain. Each heat transfer tube 11 is made of a pipe, and a gas or liquid such as steam or cold water circulates in the hollow interior. Gas or liquid is supplied to each heat transfer tube 11 through branch pipes of pipes 12 and 13 connected to each heat transfer tube 11. Note that the upper and lower ends of the heat transfer tube 11 are shielded.

  Specifically, a pipe 12 is connected to the lower end side of each heat transfer tube 11, and a pipe 13 is connected to the upper end side thereof. The pipes 12 and 13 are fixed to a first main body frame (not shown). The first heat transfer tube array 10 is also fixed to the first main body frame via the pipes 12 and 13. However, the first heat transfer tube row 10 is directly supported by the first main body frame, and the first heat transfer tube row 10 and the branch pipes of the pipes 12 and 13 are connected by a flexible tube, so that the adjacent heat transfer tubes 11 are adjacent to each other. The gap can be easily adjusted.

  The second heat transfer tube array 20 is substantially the same as the first heat transfer tube array 10, and the second heat transfer tube 11 (hereinafter simply referred to as “heat transfer tube 11”) having the same configuration as the first heat transfer tube 11. The heat transfer tube 11 and the second heat transfer tube 11 have the same configuration.) Are arranged with a predetermined gap. However, the first heat transfer tube row 10 and the second heat transfer tube row 20 are shifted by ½ pitch (adjacent interval), and the heat transfer tubes 11 are alternately arranged opposite to each other. As a result, as will be described later, the heat transfer tubes 11 facing each other when sandwiching the curtain enter the gap portion, and the first heat transfer tube row 10 and the second heat transfer tube row 20 A pleat is formed by being sandwiched. The pipes 12 and 13 described above are also connected to the heat transfer tubes 11 constituting the second heat transfer tube array 20. The second heat transfer tube row 20 and the pipes 12 and 13 are fixed to a second main body frame 14 (only a part of the second main body frame is shown in FIG. 1), and are attached to a rail (not shown). The second heat transfer tube row 20 can be moved in the direction of the first heat transfer tube row 10.

  The heat transfer tube row moving means 30 is composed of an electric or hydraulic linear actuator connected to the second main body frame 14. Thereby, the 2nd heat exchanger tube row | line | column 20 can be made to approach the 1st heat exchanger tube row | line | column 10 so that the curtain W may be inserted | pinched as shown in FIG. The heat transfer tube row moving means 30 may be another actuator, or may be configured to move the first heat transfer tube row 10 closer to the second heat transfer tube row 20 or to move both of them.

  The heating medium inflow means 40 is composed of a boiler that allows pressurized superheated steam (heating medium) to flow into the heat transfer tubes 11 of the first heat transfer tube row 10 and the second heat transfer tube row 20 through the pipe 12. In the present embodiment, in order to efficiently distribute the high-temperature superheated steam in each heat transfer tube 11, the hot superheated steam is supplied from the pipe 12 below and discharged from the pipe 13 above. The direction may be reversed.

  The cooling medium inflow means 50 is from a pump that causes cold water (cooling medium) stored in a tank (not shown) to flow into the heat transfer tubes 11 of the first heat transfer tube row 10 and the second heat transfer tube row 20 through the pipe 12. Become. In this embodiment, low-temperature cold water may be supplied from the pipe 13 located above and discharged from the pipe 12 located below the low-temperature cold water in order to efficiently flow in each heat transfer pipe 11. In addition, when supplying tap water of sufficient water pressure to each heat exchanger tube 11, a pump can be omitted. The cooling medium inflow means 50 in this case is a water supply or the like.

  Between the heating medium inflow means 40 or the cooling medium inflow means 50 and the pipe 12 or the heat transfer pipe 11, a flow path switching machine 15 including a three-way valve is installed. With the flow path switching unit 15, it is possible to supply superheated steam to the pipe 12, supply cold water to the pipe 12, or block the flow to the pipe 12. The flow path switching machine 15 is preferably composed of an electromagnetic valve or the like and can be controlled automatically or by an operator.

  The heat transfer tube 11 is a tubular member that is long and closed at both ends, and is capable of transferring internal heat to the outer surface. As shown in FIG. 2, the cross-sectional outer shape of the heat transfer tube 11 has an elliptical shape as a whole. The heat transfer tubes 11 are arranged so that the short sides of the ellipse face each other, thereby constituting the first heat transfer tube row 10 or the second heat transfer tube row 20 (see FIG. 2A). By arranging the heat transfer tubes 11 in this way, the peripheral side surface of the heat transfer tube 11 corresponding to the long side of the ellipse and the curtain W come into contact with each other in a wider area. The heat transfer tube 11 may be made of copper having a high thermal conductivity, or may be made of stainless steel having a high antirust property against superheated steam and water flowing inside.

(2) Folding A state in which the pleat processing (pleating processing, heat forming step) is performed on the curtain W using the pleat processing apparatus 1 will be described.

  First, as shown in FIG. 2A, the curtain W suspended from the rail is guided between the first heat transfer tube row 10 and the second heat transfer tube row 20.

Next, as shown in FIG. 2B, the second heat transfer tube row 20 is moved in the direction of the first heat transfer tube row 10, and the curtain W is sandwiched between the heat transfer tubes 11. The width of the pleat formed on the curtain W can be adjusted by the amount of movement of the second heat transfer tube row 20. If the length of the curtain W is not uniform, adjustment is performed by pulling the hem downward or pushing it up. In this state, when the curtain W is heated and cooled and pleats are processed, the height is also corrected, and the entire length becomes uniform.

  The curtain W sandwiched between the first heat transfer tube array 10 and the second heat transfer tube array 20 can be heated or cooled by operating the flow path switching device 15. That is, the superheated steam is made to flow into each heat transfer pipe 11 by operating the flow path switching machine 15, and when the curtain W is sufficiently heated, the flow path switching machine 15 is switched to allow cold water to flow into the heat transfer pipe 11. . When the curtain W cools, the second heat transfer tube row 20 is returned to the original position, and the curtain W is sent to the next step. Thus, the pleat processing of the curtain W is completed.

  According to the pleat processing apparatus 1 of the present embodiment, since it is not a method of injecting and heating superheated steam as in the prior art, it is not necessary to dry the curtain W, and it is possible to move to the next cleaning process or packing process. . Moreover, since the pleat processing of the present embodiment is performed by heating the curtain W, it also has effects such as pest control, sterilization, sterilization, and sterilization. Moreover, if a chemical | medical agent etc. are sprayed on the curtain W before the pleat process, the drying (heating process) of the curtain W can also be performed by the heating (heat-forming process) at the time of the pleat process. Therefore, even when the medicine is sprayed on the curtain W, the curtain W can be immediately packed without specially performing the drying process.

<< Second Example >>

The spray gun is also preferably moved from above the curtain W to below. By this medicine spraying means 80, the medicine spraying process according to the present invention can be performed.

  The dust removing means 70 includes an air shower or the like that ejects compressed air to the curtain W by an air compressor and an air gun. The air gun is preferably moved from the upper side to the lower side while jetting compressed air onto both the front and back surfaces of the curtain W. In addition, the dust removing means 70 may be, for example, a method in which dust is removed by vibration or the like, and it is more preferable to perform ultraviolet irradiation together with them. This dust removing means 70 can perform the cleaning process according to the present invention.

  The hermetic packaging means 60 includes a heat sealer that closes an opening of a synthetic resin bag containing a curtain W that has undergone a chemical spraying process, a heat forming process (a fold processing process), a cleaning process, and the like.
