JP-A-6-212562 (paragraphs 0006 to 0011) JP 2002-105855 (paragraphs 0007 to 0008)

  During the hand towel manufacturing process, the solution applied to the hand towel must be clean. However, at sites where the hand towel of the terminal is moistened, such as the sterilizing solution supply path and the supply nozzle in the devices of Patent Documents 1 and 2, even when not used, the environment is in a moist state, so that bacteria and the like are easy to propagate. Thereby, there is a problem that a contaminated hand towel is produced.

  Further, in Patent Documents 1 and 2, since a sterilizing solution generated in advance is used, the sterilizing solution is deteriorated or altered while hand towels are not manufactured.

  Therefore, an object of the present invention is to provide a sterilizing solution applying device that is generated immediately before applying a sterilizing solution and can apply a stable sterilizing solution immediately after generation to an object to be sterilized.

  In order to achieve the above object, the present invention provides a sterilizing solution application device provided with a sterilizing solution applying means for applying a sterilizing solution having a sterilizing action to an object to be sterilized. It is characterized by having.

  That is, in order to prevent the sterilizing solution from being deteriorated or altered, the sterilizing solution generating means is provided in association with the sterilizing solution applying means. Thereby, it can produce | generate immediately before providing a sterilization solution to a to-be-sterilized thing, and can always provide a clean sterilization solution to a to-be-sterilized object. Furthermore, since a storage space such as a tank for storing the sterilizing solution is not necessary, the sterilizing solution applying device can be downsized.

  The sterilizing solution generating means has an electrode made of silver, copper, zinc, or an alloy thereof, and when the electrode is energized, the sterilizing metal ions are eluted in a solvent to generate a sterilizing solution. As a result, a sterilizing solution that is harmless to the human body and has an excellent antibacterial effect can be generated. In addition, as described in paragraph “0004” of Patent Document 1, silver, copper, zinc, or metal ions thereof have a broad antibacterial spectrum and higher safety than organic antibacterial agents. .

  Here, the solvent for eluting the metal ions is not particularly limited, and water and warm water can be exemplified. It is desirable to supply the solvent immediately before the application of the sterilizing solution to generate the sterilizing solution. When it is difficult to supply the solvent directly from a supply means such as a water tap, a solvent storage unit is provided in the sterilizing solution applying device. May be temporarily stored. In that case, a sterilization solution production | generation means is provided in a solvent storage part. Thereby, it can produce | generate immediately before providing a sterilization solution to a to-be-sterilized object, can prevent deterioration, a quality change, etc. of a sterilization solution, and can always provide a clean sterilization solution to a to-be-sterilized object.

  Further, the sterilizing solution applying means can be applied by spraying the sterilizing solution onto the article to be sterilized. In this case, a spraying device for spraying the sterilizing solution is provided, and the sterilizing solution can be applied to the article to be sterilized by the spraying device. Moreover, the wet state of a to-be-sterilized object can be adjusted by providing by spraying. That is, an appropriate amount of sterilizing solution can be applied, and the process can be directly transferred to the next step. Thereby, the work process can be shortened and the production efficiency can be improved. Further, it can be applied in a small amount to a non-wetting object, such as a non-woven fabric for wiping electrical appliances.

  Moreover, as another sterilization solution provision means, it can also provide by immersing a to-be-sterilized object in a sterilization solution. Moreover, when reusing a hand towel, it is possible to have both a cleaning function and a sterilizing solution application function. For example, a sterilizing solution generating unit that generates a sterilizing solution and a cleaning unit that applies a sterilizing solution while cleaning the object to be sterilized can be provided, and the sterilizing solution can be applied to the object to be sterilized during cleaning. Further, by controlling the concentration of the sterilizing solution, a sterilizing solution having a high sterilizing effect can be provided in a small amount.

  The timing for applying the sterilizing solution to the article to be sterilized can be during conveyance of the article to be sterilized. A roller, a belt conveyor, a hand, an arm, etc. can be considered as a conveyance body which conveys to-be-sterilized material. When the carrier is a roller, metal ions are supported on the material covering the roller surface, and the metal ions are liberated and applied to the object to be sterilized when passing the object while contacting the roller surface. .

  Further, a sterilizing solution generating means can be provided in the roller. In this case, the sterilizing solution generated inside the roller is applied by supplying it to the outer periphery of the roller. Furthermore, when the conveying body is a belt conveyor, the sterilizing solution is applied by jetting from above or below. Alternatively, the roller is applied from above by contacting the object to be sterilized. When the transport body is a hand or an arm, the object to be sterilized that is being gripped and transported is immersed in a sterilizing solution. Alternatively, spray the sterilizing solution during transport.

  Further, the present invention is characterized in that a temperature adjusting means for keeping the storage temperature of the article to be sterilized in a temperature zone that enhances the sterilizing effect of the sterilizing solution is provided. Thereby, the activity of the enzyme in the life activity of bacteria can be reduced, the proliferation of various bacteria during storage can be prevented, and at the same time the bactericidal effect can be enhanced.

  As mentioned above, according to this invention, it can produce | generate just before providing a disinfection solution. This eliminates the need to temporarily store the solution during the production process, thus preventing the growth of bacteria and the like that would occur when the sterilizing solution is stored for a long time and the deterioration of the sterilizing solution itself. Can be supplied.

[First Embodiment]
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a hand towel maker equipped with a sterilizing solution applicator according to the first embodiment of the present invention, and FIG. 2 is a schematic diagram of a hand towel maker equipped with a sterilizing solution applicator having a solvent reservoir. Show.

  The hand towel maker of the present invention includes a hand towel manufacturing device 2 that manufactures the hand towel 1 and a sterilizing solution applying device 3 that applies the sterilizing solution A.

  As shown in FIG. 1, the hand towel making apparatus 2 draws out a hand towel cloth 4 wound in a roll shape by a transport device, and winds and cuts the cloth 4 to a predetermined length by a winding / cutting device 5. Thus, the rolled hand towel 1 is manufactured one after another.

  The transport device includes a driving roller 6 that is rotationally driven by a motor or the like, a driven roller 7 that faces the driving roller 6, and a guide roller 8. The driving roller 6 and the driven roller 7 sandwich the cloth 4, and the cloth 4 is pulled out by the rotation of the driving roller 6 and conveyed to the winding / cutting device 5. These conveying devices and the winding / cutting device 5 are known techniques.

  The sterilizing solution applying device 2 includes a sterilizing solution generating unit that generates the sterilizing solution A and a sterilizing solution applying unit that applies the sterilizing solution A.

  The sterilizing solution generating means includes a solvent supply unit 9 for supplying a solvent such as tap water and warm water, a sterilizing solution generating unit 10 for eluting antibacterial metal ions into the supplied solvent, a solvent supplying unit 9 and a sterilizing solution generating unit. The control part 11 which controls 10 is provided.

  The solvent supply unit 9 supplies a solvent such as tap water or hot water through a supply pipe 12 from a supply source that can be continuously supplied, such as a water tap. In addition, the solvent to supply is not restricted to these, Pure water, ion-exchange water, electrolyzed water, soft water, alcohol, etc. may be sufficient. Furthermore, you may add the finishing agent from which an aroma effect, a softening effect, etc. are acquired to a solvent.

  The sterilizing solution generator 10 includes electrodes 13a and 13b that elute metal ions, and a power source 13c that energizes the electrodes 13a and 13b. The electrodes 13 a and 13 b are interposed in the supply pipe 12. The electrode material is preferably a metal electrode made of silver, copper, zinc, or an alloy thereof. In the present embodiment, two electrodes 13a and 13b are used to elute metal ions, but three or more electrodes may be used. For example, when there are three electrodes, it may be two for the anode, one for the cathode, or one for the anode and two for the cathode. That is, it is only necessary that both the anode and the cathode have at least one sheet. As a result, when the electrodes 13a and 13b are immersed in the solvent, the electrodes 13a and 13b are energized so that the metal ions are eluted in the solvent and the sterilizing solution A is generated. Further, the polarity of the electrodes 13a and 13b may be reversed between the anode and the cathode at regular intervals. Thereby, it can prevent that scales, such as a calcium carbonate, adhere to electrodes 13a and 13b. The anode may be an electrode that elutes metal ions, and the cathode may be an electrode that does not elute metal ions, for example, an electrode such as noble metal plating, carbon, conductive plastic, or platinum.

The concentration of metal ions in the solvent is, for example, about 1 ppb to 1000 ppb when the metal ions are silver ions. More preferably, 90 ppb to 900 ppb is preferable. The bactericidal effect by this acquired the antibacterial effect with respect to Staphylococcus aureus in the cotton fabric which processed with 90 ppb silver ion water. The cotton fabric treated with 600 ppb of silver ion water obtained an antibacterial effect against ringworm. It was confirmed that the antibacterial effect was obtained with a silver adhesion amount of 25.2 ng · cm ² as the effect on the wipes. In this case, the concentration of silver ion water is 900 ppb. However, since the treatment concentration varies depending on the material of the sterilized material, the concentration of ions to be eluted is adjusted according to the application. In the adjustment method, the concentration can be adjusted by changing the amount of electricity applied between the electrodes 13a and 13b. The amount of electricity between the electrodes 13a and 13b is constant, the flow rate of the solvent supplied to the sterilizing solution generator 10 may be changed, and the energization time between the electrodes 13a and 13b may be changed.

  The supply pipe 12 is provided with a valve (not shown), and the supply of the sterilizing solution is adjusted by opening and closing. The control unit 11 controls opening / closing of the valve and on / off of the power source 13 c of the sterilizing solution generation unit 10. That is, the supply amount of the solvent can be kept constant by controlling the opening and closing of the valve provided in the solvent supply unit 9, and the sterilizing solution A having a uniform concentration can be generated. Further, by controlling the power supply 13c of the sterilizing solution generator 10, the energization time between the electrodes 13a and 13b and / or the amount of electricity to be energized can be adjusted, and only the necessary amount of the sterilizing solution A can be generated. . It is also possible to prevent the electrodes 13a and 13b from being consumed due to excessive electrolysis.

  The valve of the supply pipe 12 is provided upstream of the sterilizing solution generator 10. Thereby, when the sterilizing solution applying apparatus 3 is not used, the solvent is not stored in the sterilizing solution generating unit 10, and deterioration or alteration of the solvent can be prevented. By opening this valve, the solvent is supplied, and at the same time, the sterilizing solution A is generated by energizing the electrodes 13a and 13b. The produced sterilizing solution A is supplied as it is to the sterilizing solution applying means. That is, by opening the valve on the upstream side, the sterilizing solution A immediately after generation can be supplied to the sterilizing solution applying means.

  The sterilizing solution applying means includes a spraying device 14 for spraying the sterilizing solution A. The spraying device 14 is disposed in the vicinity of the driving roller 6 or the driven roller 7, and is connected to the sterilizing solution generator 10 through the supply pipe 12. Thereby, the spraying device 14 discharges the sterilizing solution A from the nozzle of the spraying device 14 by the supply pressure of the sterilizing solution A supplied from the sterilizing solution generation unit 10. The pressure at which the sterilizing solution is discharged from the nozzle is not limited to this, and it may be discharged by applying pressure by other power such as a pump. The spraying device 14 includes spraying from a nozzle, ultrasonic spraying, electrostatic spraying and the like, but is not particularly limited as long as it is a method capable of spraying a sterilizing solution.

  Further, instead of generating the sterilizing solution A while directly supplying the solvent, the sterilizing solution A may be generated once in the solvent stored in the sterilizing solution application device 3. In this case, as shown in FIG. 2, a solvent storage unit 15 that temporarily stores the solvent in the sterilizing solution application device 3 is provided in the hand towel maker. The solvent storage unit 15 uses an antibacterial inner wall so that the solvent can be stored for a long time. Thereby, deterioration or contamination of the solvent can be prevented. The solvent storage unit 15 includes a sterilizing solution generator 10. The sterilizing solution A is generated in the solvent storage unit 15.

  Alternatively, the sterilizing solution generator 10 may be provided in a supply path (not shown) for supplying the solvent to the solvent reservoir 15, and the sterilizing solution A may be stored in the solvent reservoir 15. In this case, the sterilizing solution A stored in the solvent storage unit 15 is stored as a stock when the amount to be applied is larger than the amount to generate the sterilizing solution A when the sterilizing solution is applied. Therefore, the sterilizing solution A remaining after the application of the sterilizing solution A is discarded from the drain (not shown). The other structure is the same as that of the hand towel making machine shown in FIG.

  Next, a description will be given of a hand towel manufacturing process using the hand towel manufacturing machine having the above-described configuration. First, the solvent is supplied from the solvent supply unit 9 to the sterilizing solution generation unit 10 via the supply pipe 12. At this time, the opening and closing of the valve is controlled by the control unit 11 to adjust the supply amount of the solvent. When the solvent is supplied to the sterilizing solution generator 10, the controller 11 turns on the power source 13c to energize the electrodes 13a and 13b. Metal ions are eluted from the electrode 13a into the solvent, and a sterilizing solution A is generated. The produced sterilizing solution A is supplied to the spraying device 14 through the supply pipe 12.

  In the spraying device 14, the sterilizing solution A is sprayed and applied to the hand towel cloth 4 drawn out by the driving roller 6. The cloth 4 to which the sterilizing solution A is applied is conveyed to the winding / cutting device 5. The conveyed cloth 4 is wound and cut to a predetermined length, and the hand towel 1 is generated.

  Thereby, when supplying the sterilization solution A produced | generated in the sterilization solution production | generation part 10 to the spraying apparatus 14, the supply pipe 12 along which the sterilization solution A passes can also be sterilized. Generation | occurrence | production of the slime etc. in the supply pipe 12 can be suppressed, and the cloth 4 can be moistened with cleaner sterilization solution A. Further, since the sterilizing solution A can be generated in the hand towel maker, it is not necessary to supply the sterilizing solution A from the outside as in the conventional case, and the cost can be reduced. Furthermore, the application of the sterilizing solution A by the spraying device 14 can adjust the wet state of the cloth 4, so that it is not necessary to squeeze the cloth 4 later. Therefore, since it can be packaged and sealed immediately after the sterilizing solution A is applied, the towel 1 can be stored more cleanly. In addition, the sterilizing solution A can be applied with a small amount of sterilizing solution even for those which are not preferable to be wet.

  In the first embodiment, the sterilizing solution generator 10 and the supply pipe 12 are provided inside the hand towel manufacturing apparatus 2, but the present invention is not particularly limited thereto, and the structure is provided outside the hand towel manufacturing apparatus 2. Also good.

[Second Embodiment]
FIG. 3: shows the schematic block diagram of the hand towel maker provided with the disinfection solution provision apparatus by the roller which is 2nd Embodiment. As shown in FIG. 3, the sterilizing solution applying means according to the present embodiment is configured such that metal ions are supported on the driven roller 7, and the sterilizing solution A is generated by spraying the solvent on the driven roller 7. The solution A is applied to the cloth 4.

  Specifically, the driven roller 7 has a roller surface coated with a porous material such as sponge or ceramic. Metal ions are supported on the surface of the driven roller 7. The solvent is sprayed from the spraying device 14 to the driven roller 7 carrying the metal ions. By impregnating the driven roller 7 with a solvent, the supported metal ions are released and a sterilizing solution A is generated. The produced sterilizing solution A is applied to the cloth 4 passing through the driven roller 7. The amount of metal ions supported on the driven roller 7 is preferably such that when the metal ions are silver ions, the silver ion concentration in the sterilizing solution 2 is about 1 ppb to 1000 ppb, and as described above. 90 ppb to 900 ppb are preferred. In addition, in other structures, such as the solvent supply part 9 and the hand towel manufacturing apparatus 2, it is the same as that of the hand towel manufacturing machine of 1st Embodiment.

  In the hand towel maker having the above configuration, when the valve of the solvent supply unit 9 is opened, the solvent is supplied to the spraying device 14 through the supply pipe 12. The solvent supplied to the spraying device 14 is sprayed on the driven roller 7. At this time, since the driven roller 7 rotates following the drive roller 6, the solvent can be sprayed around the entire circumference. The cloth 4 is pulled out from the state wound by the drive roller 6 and passes through the driven roller 7 impregnated with the sterilizing solution A. As a result, the sterilizing solution A is applied to the cloth 4. The cloth 4 to which the sterilizing solution A is applied is transported to the winding / cutting device 5 in the same manner as the hand towel making machine shown in FIG.

  Thereby, the electrolysis for obtaining the sterilizing solution A is not necessary, and advantages such as energy saving and low cost can be obtained. The power source 13c for electrolysis is not required, the weight can be reduced, and the hand towel maker can be downsized. In addition, since the sterilizing solution A containing metal ions does not pass through a long path before being applied to the cloth 4, more metal is not adsorbed on the wall surface of the supply pipe 12 and the like. Ions can be applied. In the above embodiment, the sterilizing solution A is generated by spraying the solvent on the driven roller 7, but the driven roller 7 may be immersed in the solvent. Alternatively, the solvent may be sprayed on or dipped in the drive roller 6 instead of the driven roller 7. Further, a solvent may be supplied to both rollers 6 and 7 (including spraying and immersion). Further, instead of metal ions or in combination with metal ions, a driving roller 6 and a driven roller 7 carrying a sterilizing substance are impregnated with a solvent, and when the cloth 4 passes through both rollers 6 and 7, it is used for sterilization. Liquid A may be applied.

[Third Embodiment]
FIG. 4: shows the figure which shows the disinfection solution provision apparatus built in the roller which is 3rd Embodiment. As shown in FIG. 4, a sterilizing solution generator 10 is provided inside the driven roller 7 as the sterilizing solution generator of the present embodiment. In this case, the driven roller 7 is formed by an open cell body 16 such as sponge or urethane. By impregnating the open cell body 16 with the sterilizing solution A, the sterilizing solution A can be supplied to the outer peripheral surface of the driven roller 7 and functions as a sterilizing solution applying means.

  The inside of the driven roller 7 serves as a container 17 that constitutes a solvent storage unit 15 that stores the solvent. A large number of permeation holes 18 are provided on the outer peripheral surface of the container 17. The solvent storage unit 15 includes electrodes 13 a and 13 b of the sterilizing solution generation unit 10, and a power source 13 c is attached to the outside of one end of the container 17. A solvent supply unit 9 is connected to one end of the container 17 via a supply pipe 12. Thereby, the driven roller 7 can generate the sterilizing solution A inside the container 17. In addition, in other structures, such as the solvent supply part 9 and the hand towel manufacturing apparatus 2, it is the same as that of the hand towel manufacturing machine of 1st Embodiment.

  According to the above configuration, the solvent is supplied from the solvent supply unit 9 to the container 17 through the supply pipe 12. The controller 11 energizes the two electrodes 13a and 13b. Metal ions are eluted in the solvent, and a sterilizing solution A is generated. The sterilizing solution A is discharged from the permeation hole 18 by the supply pressure from the solvent supply unit 9 and is supplied to the open cell body 16 through the permeation hole 18. In this case, the driven roller 7 is supported so that only the open cell body 16 rotates following the drive roller 6, and the container 17 does not rotate. When the cloth 4 passes while contacting the surface of the driven roller 7 impregnated with the sterilizing solution A, the sterilizing solution A is applied to the cloth 4. As described above, the cloth 4 to which the sterilizing solution A is applied is conveyed to the winding / cutting device 5, wound up to a predetermined length, and cut. The hand towel 1 rolled with the sterilizing solution A is produced one after another.

  With the above structure, a space for installing the sterilizing solution generator 10 is not necessary, the weight can be reduced, and the hand towel maker can be downsized. Further, since the sterilizing solution A containing metal ions does not go through a long path before being applied to the cloth 4, loss of metal ions in the sterilizing solution A during supply can be reduced, and more metal ions can be added. Can be granted. The driven roller 7 and the container 17 are rotated integrally by, for example, the driven roller 7 including the container 17 following the drive roller 6, and the permeation hole is generated by centrifugal force or supply pressure from the solvent supply unit 9. The sterilizing solution A may be discharged from 18. Further, the sterilizing liquid generator 10 may be provided on the driving roller 6 or on the driving roller 6 and the driven roller 7.

[Fourth Embodiment]
As mentioned above, although the hand towel making machine which provides the sterilizing solution A before cutting | disconnecting the cloth 4 was demonstrated, you may provide the sterilizing solution A to what cut | disconnected the cloth 4 to predetermined length. Below, the hand towel making machine which provides the sterilizing solution A to the cut cloth 4 will be described.

  FIG. 5: shows the schematic block diagram of the hand towel maker provided with the sterilization solution provision apparatus incorporated in the washing | cleaning apparatus which is 4th Embodiment. As shown in FIG. 5, the hand towel making machine of the present embodiment cuts the cloth 4 into a predetermined length, and then cleans and conveys the cloth 4 by the belt conveyor 19, and successively manufactures the hand towels 1 that are rolled and packaged. In this case, the sterilizing solution A is applied during cleaning.

  The hand towel making machine includes a cleaning device 20 that cleans the cut cloth 4, a belt conveyor 19 that transports the cleaned cloth 4, a winding device 21 that rounds the transported cloth 4, and the wound fabric 4. Is composed of a wrapping device 22 and a sterilizing solution applying device 3. Washing is a washing process in which dirt or the like is washed with a detergent or a bleaching agent, a rinsing process in which the remaining detergent or bleaching agent adhering to the washed cloth 4 is washed away with water or hot water, 4 is composed of a dehydration process in which the water contained in 4 is dispersed using centrifugal force, heat, or the like, and one washing is completed by performing the washing process, the rinsing process, and the dehydration process in this order. Furthermore, the used towel 1 may be put into the cleaning device 20, and the towel 1 can be regenerated.

  The washing device 20 is provided with a washing tub 23 for washing the cloth 4, and a sterilizing solution generator 10 having electrodes 13 a and 13 b and a power source 13 c is provided in the rinse water supply path of the washing tub 23. Thereby, a metal ion can be eluted in rinse water and the sterilization solution A can be produced | generated. The sterilizing solution A is given to the cloth 4 by using the produced sterilizing solution A in the rinsing process. Therefore, the sterilizing solution application device 3 includes the sterilizing solution generator 10 and the cleaning device 20. The cleaning device 20 functions as a solvent supply unit 9 that supplies a solvent and a sterilizing solution application unit that applies the sterilizing solution A. A control unit that drives and controls the cleaning device 20 controls the sterilizing solution application device 3 in the same manner as described above.

  In addition, although the process until it cut | disconnects the cloth 4 to predetermined length is the same as the process until it cut | disconnects the cloth 4 in 1st Embodiment, you may use the cloth 4 cut | disconnected previously. When the cloth 4 in the first embodiment is used, the cloth 4 may be stained while being cut and transported. Therefore, the cloth 4 is cleaned by a cleaning unit before applying the sterilizing solution. In order to more reliably apply the sterilizing solution A to the cloth 4, the sterilizing solution A may be used from the washing step to the rinsing step.

  In the above configuration, the cloth 4 cut to a predetermined length is placed in the washing tub 23 and washed. After the washing process is completed, the rinsing process is started, and the sterilizing solution generator 10 operates to elute metal ions in the rinsing water to generate the sterilizing solution A. The produced sterilizing solution is discharged from the rinse port of the rinse water, and the sterilizing solution A is applied to the cloth 4 while rinsing. The cloth 4 to which the sterilizing solution A is applied proceeds to the dehydration process as it is. At this time, dehydration is performed to such an extent that the applied sterilizing solution does not disappear. After the dehydration process is completed, the cloth 4 is conveyed to the winding device 21 by the belt conveyor 19. The cloth 4 is wound into a roll by the winding device 21 and then moves to the packaging device 22. In the packaging device 22, the roll-shaped cloth 4 is packaged in a bag, and the hand towel 1 is manufactured one after another. Thereby, the hand towel maker can perform washing | cleaning of the cloth 4 and provision of the sterilizing solution A to the cloth 4 simultaneously, and can process it in large quantities at once.

[Fifth Embodiment]
FIG. 6: shows the schematic block diagram of the hand towel manufacturing machine which has a sterilizing solution provision apparatus in the belt conveyor which is 5th Embodiment. Application | coating of the sterilizing solution of this embodiment may be provided after washing | cleaning instead of providing the sterilizing solution A during washing | cleaning, and the cloth 4 is immersed in the sterilizing solution A during conveyance, as shown in FIG. In this case, a box-like sterilizing solution storage tank 24 for storing the sterilizing solution A is provided on the path of the belt conveyor 19 that conveys the cloth 4. When the belt conveyor 19 passes through the sterilizing solution storage tank 24, the belt conveyor 19 is guided to be recessed. The sterilizing solution storage tank 24 is connected to the solvent supply unit 9 via the sterilizing solution generation unit 10 by the supply pipe 12. The supply speed of the sterilizing solution A to the sterilizing solution storage tank 24 is supplied to such an extent that the sterilizing solution A is not depleted. A supply amount may be adjusted by providing a valve.

  Further, the sterilizing solution reservoir 24 is provided with a discharge pipe 25 for discharging the sterilizing solution A that has been used. The discharge pipe 25 directly discharges the used sterilizing solution A to the outside of the hand towel maker. You may connect with the sterilization solution production | generation part 10, and may circulate so that it can utilize as a solvent again. In this case, the used sterilizing solution A needs to be washed once before reaching the sterilizing solution generation unit 10 to be in a clean solvent state. The drainage of the sterilizing solution A is performed when metal ions in the sterilizing solution A are reduced, or when the sterilizing solution A itself is altered or contaminated.

  The structure of the hand towel manufacturing apparatus 2 is the same as that of the hand towel manufacturing machine of the first embodiment. Moreover, you may provide the washing | cleaning means of 4th Embodiment.

  In the above configuration, the cloth 4 is conveyed by the belt conveyor 19 and passes through the cleaning solution storage tank 24. At this time, the cloth 4 passes through the sterilizing solution A stored in the sterilizing solution storage tank 24. That is, the cloth 4 is immersed in the sterilizing solution A, and the sterilizing solution is applied. The cloth 4 to which the sterilizing solution A is applied is squeezed with excess moisture by a compressor (not shown) such as a roller. At this time, it is preferable to dehydrate so that the sterilizing solution A remains on the cloth 4 as much as possible by adjusting the compression pressure. The dehydrated cloth 4 is conveyed to the winding device 21 by the belt conveyor 19, and the cloth 4 is wound into a roll shape by the winding device 21. After that, it moves to the packaging device 22 and the roll-like cloth 4 is packaged in a bag and carried out.

  Thereby, the hand towel 1 is given the sterilizing solution A while being conveyed on the belt conveyor 19. Since the entire towel 1 is immersed in the sterilizing solution A, the sterilizing solution A can be applied to the towel 1 evenly.

  In this embodiment, the sterilizing solution A is stored and applied in the sterilizing solution storage tank 24.
