Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a wet sheet take-out device, and more particularly to a mechanism for taking out a wet sheet such as a wet tissue or wet paper towel which is obtained by immersing a water-containing sheet such as a paper sheet or a non-woven fabric in a liquid such as water or alcohol.

[0002]

[Prior art]

 Conventionally, various wet sheet take-out containers configured to take out wet tissues and the like are commercially available. In many cases, the outlet of these containers is an insertion hole having a narrowed shape, a cross-shaped cut formed in a flexible resin plate, or a hole having a star-shaped cross section.

[0003]

[Problems to be solved by the device]

 The wet sheet takeout container as described above may be used, for example, when the body is wiped when caring for an infant or caring for an elderly person. In this case, in the case where a predetermined amount of liquid is contained in advance and the liquid is taken out from the simple outlet as described above, the amount of liquid impregnated into the sheet is predetermined, and the sheet is sized according to the usage situation. It is difficult to obtain the optimum liquid content of the sheet, and since the liquid content of the sheet cannot be adjusted, there is a problem that the usability is poor.

In addition, in the above-mentioned applications, by keeping the wet sheet warm, it is possible to enhance the sheet cleaning ability and prevent the user from feeling a cold sensation. However, in order to immerse the water-containing sheet in a high-temperature liquid such as hot water, a container for keeping the temperature of the liquid and a mechanism for appropriately supplying the high-temperature liquid to the water-containing sheet are necessary. With the conventional type that keeps a certain amount of the sheet in it, the heat retaining time is limited even if it is put in a heat retaining container. There is a risk of being burned after being taken out, and on the other hand, the content of the high temperature liquid may be too low.In this case, the sheet temperature has already dropped too much when the sheet is taken out and used. The situation occurs.

In addition, conventionally, since the water-containing sheet has various thicknesses, materials, and sizes, it is necessary to appropriately adjust the size and shape of the outlet according to these conditions. However, complicated adjustment work was required for each hydrous sheet. For example, if the sheet is perforated and the sheet is pulled out, after the perforation passes through the take-out port, the pull-out resistance at the take-out port is set appropriately so that the sheet naturally breaks along the perforation. This is because it needs to be set. This operation is extremely difficult because the amount of liquid impregnated into the sheet must be adjusted when the high temperature liquid is impregnated as described above.

Therefore, the present invention is to solve the above-mentioned problems, and an object thereof is to improve the structure in the vicinity of the outlet of the wet sheet extractor to take out the sheet in a state in which the liquid is appropriately impregnated. To obtain a wet sheet ejector. Also, to realize a wet sheet take-out device capable of adjusting the impregnated amount of the sheet, and to provide a technique that can be comfortably used with a favorable impregnated amount even when impregnating a liquid of high temperature. It is in. Further, it is to realize a structure in which the sheet take-out device having the above-mentioned function can be used more easily.

[0007]

[Means for Solving the Problems]

 Means taken by the present invention for solving the above-mentioned problems include a sheet storage portion configured to store a liquid-containing sheet, and a pressing portion arranged at a sheet extraction portion of the sheet storage portion. The liquid is supplied to the pressing member, the roller arranged so that the peripheral surface comes into contact with or comes close to the pressing portion of the pressing member, and the peripheral surface of a portion of the peripheral surface of the roller other than the portion facing the pressing portion. And a liquid supply means for supplying the liquid, and at least the peripheral surface of the roller is configured to be liquid-containing, and the liquid-containing sheet can be taken out from between the pressing member and the roller. It is a characteristic wet sheet extractor.

According to this means, the peripheral surface of the roller is made to be liquid-containing, and the liquid is supplied to a part of the peripheral surface other than the part facing the pressing member. By pulling out between the pressure member and the roller, the sheet can be made to contain the liquid from the peripheral surface of the roller containing the liquid, so it is possible to add the liquid in advance or dip the sheet in the liquid. It is easy to take out a sheet containing a certain amount of liquid without needing to keep it, and even if it is a sheet made of a material that becomes weak when impregnated with a liquid in order to supply the liquid in the process of withdrawing, it may tear. It can be taken out without fail.

Here, it is preferable that the liquid supply unit is configured to have a structure in which the peripheral surface of the roller is immersed in the liquid contained in a liquid tank provided below the roller.

According to this means, the liquid can be supplied to the roller simply by immersing the peripheral surface of the roller in the liquid tank, so that the liquid supply means can be simply configured.

Further, driving means for rotating the roller so as to pull out the sheet sandwiched between the pressing member, control means for operating the driving means in a predetermined operation mode, and the control means. It is preferable to have an operation section for operating the drive means via the.

According to this means, the drive means can be operated via the control means by operating the operation portion, so that the rotation of the roller causes the drive means to operate between the pressing means and the pressing member. The sandwiched sheet can be automatically pulled out, and even sheets of weak material can be reliably pulled out without breaking.

Further, it is preferable that the pressing member and the roller are configured to be pressed with a predetermined pressure in a direction in which they approach each other.

According to this means, since the pressing member and the roller are configured to press each other, the sheet sandwiched between the two can be pulled out while being squeezed by a predetermined pressure, and the pressure causes the sheet to move. It becomes possible to take out after adjusting the liquid content.

[0015]

[Embodiment of device]

 Next, an embodiment of a wet sheet takeout device according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an overall configuration of an embodiment according to the present invention. In this embodiment, a roll 12 around which a sheet 11 to be described later is wound is housed inside the main body container 10 having a box shape, and the sheet 12 is pulled forward from the roll 12. It is in the state of being

A liquid tank 13 is arranged in front of the housing portion of the roll 12, and hot water is stored in the liquid tank 13. Inside the liquid tank 13, a roller 14 is rotatably supported around its central axis 14a, and the lower surface of the roller 14 is immersed in the hot water of the liquid tank 13. . A liquid-containing film 15 having a water-absorbing property is attached to the peripheral surface of the roller 14, and the liquid-containing film 15 contains hot water. The central shaft 14a of the roller 14 is supported by bearings 16 mounted on the left and right side surfaces of the liquid tank 13.

A pressing roller 21 as a pressing member is arranged above the roller 14 and is rotatably supported around a center shaft 21a thereof. The central shaft 21a of the pressing roller 21 extends left and right from both end surfaces of the roller 21, and is formed in a vertically extending elongated hole 10b formed in a pair of left and right shaft supporting portions 10a formed in the upper portion of the main body container 10. It has been inserted. Therefore, the pressing roller 21 is rotatably supported in the vertical direction.

An elastic member 22 is attached between the central shaft 21a and the bearing portion 16, and the elastic member 22 urges the roller 14 and the pressing roller 21 in a direction in which they approach each other. It is configured.

The sheet 11 is drawn out from between the peripheral surface of the roller 14 and the peripheral surface of the pressing roller 21, and is taken out from an outlet 10 c formed on the front surface of the main body container 10.

The central shaft 14 a of the roller 14 is taken out of the liquid tank 13 and connected and fixed to the drive pulley 17. A drive belt 18 is mounted on the drive pulley 17, and the drive belt 18 is also mounted on an output pulley 19 connected and fixed to the output shaft of a drive motor 20. With such a configuration, when the drive motor 20 operates, the central shaft 14a is rotationally driven via the drive belt 18. Then, the roller 14 pulls out the sheet 11 sandwiched between the roller 14 and the pressing roller 21 from the roll 12 and discharges it from the front outlet 10c.

The liquid tank 13 is built in the main body container 10 via a heat insulating material (not shown) and / or a depressurized space, and is configured to hold hot water having a temperature of about 60 ° C., for example. In addition, a heating device may be attached to the lower part of the liquid tank 13 to heat the liquid tank 13 to a desired temperature and maintain the temperature. In this case, it is preferable that the heating device be configured so that the control temperature can be adjusted appropriately by operating buttons provided on an operation panel (not shown) on the outer surface of the main body container 10.

The roll 12 is, for example, a pulp nonwoven fabric of 80 g / m ² or 50 g / m ² formed into a length of 300 mm and a width of 250 mm and wound into a roll diameter of 130 mm. As a substitute for the roll 12, a paper roll made of various specially processed paper or a cloth formed of synthetic fibers other than paper can be considered, but it is disposable and has sufficient heat retention and strength. In view of the above, the above-mentioned pulp nonwoven fabric is most preferable.

In this embodiment, when the operation button (not shown) is operated, the drive motor 20 causes the roller 14 to rotate, and the sheet 11 having a predetermined length is pulled out. Since the sheet 11 is automatically pulled out by rotating the roller 14 by the driving means in this manner, the sheet 11 is not subjected to excessive tension, and even a sheet made of a fragile material can be reliably taken out. it can. Further, since water is supplied to the sheet 11 only when it is drawn out, even a sheet made of a material that becomes weak in a liquid-containing state can be taken out without trouble.

On the surface of the liquid-containing film 15 of the roller 14, knurls are formed to prevent the sheet from slipping, which will be described later, or a rubber net to prevent slipping is attached. The structure for slipping may be formed on the peripheral surface of the pressing roller 21.

When the leading end of the sheet 11 pulled out from the roll 12 is pulled, the sheet 11 is taken out in a state of being sandwiched between the peripheral surface of the roller 14 and the peripheral surface of the pressing roller 21, so that the roller 14 The hot water contained in the liquid-containing film 15 attached to the peripheral surface of the sheet is absorbed by the sheet 11, and the water is appropriately squeezed by the sandwiching pressure received from the roller 14 and the pressing roller 21. The degree of this throttling is determined by the clamping pressure provided by the elastic member 22.

Therefore, the pull-out resistance of the roll 12 can be adjusted by the elasticity of the elastic member 22. In this adjustment, when it is necessary to change the pull-out resistance depending on the thickness and width of the sheet 11 of the roll 12, the necessary tearing-off that changes according to the width of the perforations formed on the sheet 11 to be described later. This is done when it is necessary to adjust the pullout resistance to force.

Perforations that extend in the width direction are formed at regular intervals on the sheet 11 that constitutes the roll 12, and the ratio between the length A of the perforations and the length B between the perforations is determined. Thus, the ease of cutting the sheet 11 can be changed. This perforation has sufficient strength so as not to be cut inside the main body container 10 when pulling out the sheet 11 from the roll 12, and at the same time, to some extent not to make cutting difficult after pulling out. It must be easy to cut.

In the perforation in the present embodiment, the length A of the cut is set to 8 mm and the length between the cuts is set to 1 mm. Even with this setting, when the two types of rolls 12 having different thicknesses of the sheet 11 are used as described above, the pressing force between the roller 14 and the pressing roller 21 is changed according to the thickness of the sheet 11. The pressure needs to be adjusted.

In the above embodiment, the drive motor 20 is configured to operate for a predetermined time by a control circuit (not shown). This control circuit drives the drive motor 201 for a short time (for example, 1 second) when one operation button is pressed for a short time (for example, less than 1 second), and when the operation button is pressed for a long time (for example, 1 second or more). It is configured to drive for a predetermined time (for example, 5 seconds). Such a configuration can be easily configured by an electronic circuit including a flip-flop, a comparator, a timer, etc., and a microprocessor unit having a program installed therein.

The driving of the drive motor 20 for a long time is associated with the interval of the perforations formed on the above-mentioned sheet 11, and by pressing the operation button for a long time, the drive motor 20 is separated by the perforations. You can take out one sheet. If the sheet cannot be taken out by the desired length, the operation button can be pressed for a short time to adjust the taking-out length of the sheet.

Further, by pushing the other operation button, the operating time (5 seconds mentioned above) of the drive motor 20 when the above operation button is pushed for a long time is extended or shortened. You can do it. This configuration can be realized by changing the reference voltage when operating the electronic circuit by operating the operation button, changing the set value of the timer, and the like. In the present embodiment having the above-described structure, as shown in FIG. 1, the leading end of the sheet 11 is sandwiched between the roller 14 and the pressing roller 21, and the roller 14 is rotated. The front end of the seat 11 can be pulled out forward. In this case, since the sheet 11 is pulled out in a flatly stretched state, even if the sheet 11 is made of a fragile material, it can be taken out without breaking.

In the present embodiment, the liquid-containing film 15 attached to the roller 14 can impregnate the sheet 11 with hot water, and the roller 14 and the pressing roller 21 can appropriately squeeze the hot water. As a result, the amount of hot water impregnated can be set appropriately, and accidents such as burns due to too much hot water impregnation can be prevented.

In the above embodiment, the roller 14 driven to rotate by the drive motor 20 and the pressing roller 21 as a pressing member are attracted to each other by the elastic member 22, but both or one of them is biased by the elastic member. They may be pressed against each other. Also, an adjusting mechanism for adjusting the sandwiching force between both rollers may be provided.

In the present embodiment, the pressing roller 21 that faces the roller 14 is provided, but instead of the pressing roller 21, the pressing surface that faces the peripheral surface of the roller 14 is placed at a position that faces the roller 14, for example. It may be configured by the provided block material or a plate-shaped elastic member.

Further, although the liquid-containing film 15 is attached to the roller 14, the roller 14 itself may be made of a liquid-containing material such as a sponge. Further, although the roller 14 is configured to be rotationally driven by the drive motor 20, the pressing roller 21 may be configured to be rotationally driven conversely.

[Effect of device]

 As described above, the present invention has the following effects.

According to the first aspect, the peripheral surface of the roller is made to be liquid-containing, and the liquid is supplied to a part of the peripheral surface other than the part facing the pressing member. By pulling out from between the pressing member and the roller, the liquid can be contained in the sheet from the peripheral surface of the roller containing the liquid. A sheet containing a certain amount of liquid can be easily taken out without needing to keep it, and even a sheet made of a material that becomes weak when impregnated with a liquid is torn in order to supply the liquid in the process of withdrawing. It can be taken out without any trouble.

According to the second aspect, since the liquid can be supplied to the roller only by immersing the peripheral surface of the roller in the liquid tank, the liquid supply means can be simply configured.

According to the third aspect, since the drive means can be operated via the control means by operating the operation portion, the sheet is not pulled and the space between the roller and the pressing member is generated by the rotation of the roller. The sheet sandwiched between the sheets can be automatically pulled out, and even sheets of weak material can be reliably pulled out without breaking.

According to the fourth aspect, since the pressing member and the roller are configured to press each other, it is possible to draw out the sheet sandwiched between the two while squeezing the sheet by a predetermined pressure, and the sheet is pressed by the pressure. It becomes possible to take out after adjusting the liquid content of.
