Description

[Detailed description of the device]

[0001]

[Industrial applications]

 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, by keeping the wet sheet warm, the cleaning ability of the sheet can be enhanced and the user can be prevented from feeling a cold sensation. However, in order to immerse the hydrous sheet in hot liquid such as hot water, a container for keeping the liquid warm and a mechanism for appropriately supplying the hot liquid to the hydrous sheet are required. At the outlet of a conventional wet sheet take-out container, the sheet may be taken out in a state in which a high temperature liquid is contained more than necessary, and there is a risk of burns. On the contrary, there is a possibility that the content of the high temperature liquid is too small, and in this case, when the sheet is taken out, the situation that the sheet temperature is already too low occurs.

Further, conventionally, since the water-containing sheet has various thicknesses, materials, and sizes, it is necessary to form the outlet by appropriately adjusting 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 solves the above-mentioned problems, and by improving the structure in the vicinity of the outlet of the wet sheet extractor, it is possible to take out the high temperature liquid while being appropriately impregnated. The purpose of the present invention is to enable effective use of wet sheets and to easily cope with various water-containing sheets.

[0006]

[Means for Solving the Problems]

 Means taken by the present invention to solve the above-mentioned problems are arranged in a sheet storage unit configured to store a water-containing sheet by immersing it in a liquid and a removal unit of the sheet storage unit. A sheet insertion hole, a pair of rollers provided with an abutting portion located outside the sheet insertion hole, a support structure configured to move at least one of the rollers, and a direction in which the rollers approach each other. A wet sheet take-out device comprising: a biasing unit that biases the biasing unit and a biasing force of the biasing unit or a roller adjusting unit that adjusts a gap between the rollers.

Here, it is preferable that the sheet insertion hole is formed with a diameter smaller than the width of the roller.

Further, it is preferable that the support structure is a structure that supports at least one of the rollers so as to be rotatable about an axis substantially parallel to the axis thereof.

Further, it is preferable that the roller adjusting means is a means for adjusting a compression state of a spring member that biases one of the rollers in a direction of approaching the other roller.

Further, a cover member for covering the pair of rollers is provided, the cover member is attached to the sheet storage portion so as to be openable and closable, and one of the rollers is attached to the sheet storage portion. It is preferable that the other is attached to the cover member.

[0011]

[Action]

 According to the first aspect, when the water-containing sheet immersed in the liquid in the sheet storage portion is set to be pulled up through the sheet insertion hole and pulled out through the abutting portion of the pair of rollers, the water-containing sheet is urged by the biasing means. The liquid is squeezed by the rollers, and the liquid is squeezed out when it is pulled out. When the water-containing sheet is perforated, the roller imparts an appropriate pullout resistance, so that the sheet can be cut at the perforations when pulled out. Since the biasing force or the roller interval can be adjusted by the roller adjusting means, it is possible to adjust the roller according to the type of sheet and realize the optimum take-out state.

According to the second aspect, since the water-containing sheet is squeezed in front of the abutting portion of the roller by making the sheet insertion hole smaller in diameter than the width of the roller, the abutting of the roller can be performed in a state where the sheets are gathered. Since the roller passes through the portion, the urging force can be reliably transmitted from the roller to the water-containing sheet, and the liquid can be squeezed down and pull-out resistance can be reliably and stably performed.

According to the third aspect of the present invention, the supporting structure is such that at least one of the rollers is rotatably supported about an axis substantially parallel to the axis of the roller. It can be moved.

According to the present invention, the roller adjusting means is a means for adjusting the compression state of the spring member for urging one of the rollers in the direction of approaching the other roller, so that the roller has a simple structure. The pressing force on the sheet can be adjusted.

According to the fifth aspect, one of the rollers is attached to the sheet accommodating portion and the other of the rollers is attached to the cover member, so that the other roller can be separated from the one roller by opening the cover. In addition to this, the seat accommodating portion can be opened wide, which makes it extremely easy to attach and detach the seat.

【Example】

 Next, an embodiment of the wet sheet take-out device according to the present invention will be described with reference to the drawings.

First Embodiment FIG. 1 is a vertical sectional view showing the overall structure of the first embodiment. In this embodiment, a container 1 having a heat retaining structure similar to a normal heat retaining pot, a cover 2 attached to the container 1 so as to be openable and closable, and an opening 2a formed in the cover 2. And a take-out mechanism 5 attached to the upper opening of the container 1.

The storage container 1 has an internal container 10 built-in through a heat insulating material and / or a decompressed space. It is designed to immerse the le 4.

The roll 4 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 an alternative to the roll 4, a paper roll made of various specially processed paper or a cloth made of synthetic fibers other than paper can be considered, but it is disposable and has sufficient heat retention and strength. The above-mentioned pulp non-woven fabric is most preferable in that it is present.

A cover 2 is attached to the upper part of the container 1 so as to be rotatable around a hinge shaft 21. The cover 2 is provided with a lock mechanism (not shown) so that the cover 2 can be rotated with respect to the container 1. It is preferable that the closed state can be maintained.

A cap 3 is fitted into the opening 2a provided in the cover 2, and the cap 3 is kept closed with respect to the cover 2 by a lock mechanism (not shown). It is preferably configured.

The upper end of the container 1 is covered with a take-out mechanism 5 so as to close the upper opening 10 a of the inner container 10. The take-out mechanism 5 is composed of a disk-shaped bottom plate 51 formed so as to fit almost exactly inside the container 1, and a mechanism portion fixed on the bottom plate 51.

An annular seal frame 52 made of a flexible material such as synthetic rubber is attached to the outer periphery of the bottom plate 51, and the bottom plate 51 is fixed in close contact with the inner surface of the container 1 by this seal frame 52. It is supposed to be done.

The central portion of the bottom plate 51 is recessed slightly downward, and an insertion hole 51a is formed at the center of the recess. A ring frame 53 made of synthetic rubber or resin is attached to the inner edge of the insertion hole 51a.

As shown in FIG. 2, the mechanism portion fixed on the bottom plate 51 is directly fixed on the bottom plate 51, and the main plate 54 having an opening 54a at the center and the main plate 54 directly. A first roller 55 that is rotatably supported, a moving lever 56 that is rotatably supported by a main plate 54 around a rotating shaft 56a, and a shaft that is rotatable with respect to the moving lever 56. A spring force of a coil spring 58 is interposed between the supported second roller 57 and the moving lever 56 and the base plate 54 to urge the second roller 57 to be pressed by the first roller 55 and A pressure adjusting mechanism having an adjusting dial 59 for adjusting the pressing force is provided.

The second roller 57 is normally pressed against the first roller 55 by the elastic force of the coil spring 58, but by pressing the first moving lever 56 downward with a finger or the like to rotate it, the first roller 57 is rotated. It is designed to be able to widen the distance from 55. The abutting portion between the first roller 55 and the second roller 57 is arranged just above the insertion hole 51a.

As shown in FIG. 3, the pressure adjusting mechanism allows the shaft portion of the adjusting dial 59 to mesh with the screw hole formed in the moving lever 56, and is further coaxially rotatable with respect to the spool 61 below the screw hole. It is installed. A disc-shaped collar portion 62 is integrally formed at the upper end of the spool 61, and the lower end of the shaft-shaped portion extending downward from the collar portion 62 is loosely fitted inside a through hole formed in the bottom plate 51. Has been inserted in.

A conical coil spring 58 is housed in a compressed state between the collar portion 62 and the base plate 54 fixed on the bottom plate 51. A notch groove 62a is formed in a part of the outer periphery of the collar portion 62, and a fixed shaft 63 protruding from the lower surface of the moving lever 56 is engaged with the notch groove 62a to prevent the spool 61 and the collar portion 62 from rotating. ing.

Here, the elastic force that sandwiches the first roller 55 and the second roller 57 from each other can be adjusted by rotating the adjustment dial 59. As shown in FIG. 4A, when the adjustment dial 59 is screwed into the moving lever 56 deeply, the gap between the collar portion 62 and the base plate 54 is narrow, so that the coil spring 58 is largely compressed and the first roller 55. And the second roller 57 is narrowed or the second roller 57 is strongly pressed against the first roller 55.

On the other hand, as shown in FIG. 4B, when the adjustment dial 59 is rotated to make the screwing into the moving lever 56 shallower, the compression state of the coil spring 58 becomes weaker, and the first roller 55 and the second roller 57. Or the pressing force of the second roller 57 against the first roller 55 becomes weaker.

Therefore, the pull-out resistance of the roll 4 can be easily adjusted by rotating the adjustment dial 59. This adjustment is based on the necessary tearing force that changes according to the width of the perforations formed on the roll 4 when it is necessary to change the pullout resistance depending on the thickness and width of the nonwoven fabric 40 of the roll 4. On the other hand, it is performed when it is necessary to adjust the extraction resistance.

FIG. 5 shows a state in which the nonwoven fabric 40 of the roll 4 is expanded. The non-woven fabric 40 forming the roll 4 is formed with perforations 42 extending in the width direction at regular intervals. Depending on the ratio of the length A of the perforations 42 and the length B between the perforations, The easiness of cutting the woven cloth 40 can be changed. This perforation 42 has sufficient strength so that it does not break inside the container 1 when the nonwoven fabric 40 is pulled out from the roll 4, and at the same time, it does not become difficult to cut after pulling out. It is necessary to have a certain degree of ease of cutting.

In the perforation 42 in the present embodiment, the length A of the break is set to 8 mm and the length between the breaks is set to 1 mm. Even with this setting, when the two types of rolls 4 having different thicknesses of the non-woven cloth 40 are used as described above, the first roller 55 and the second roller 57 can be used according to the thickness of the non-woven cloth 40. It is necessary to adjust the pressing force between and.

As shown in FIG. 4A, the take-out mechanism having the above-described structure sandwiches the tip end portion 41 of the nonwoven fabric 40 of the roll 4 between the first roller 55 and the second roller 57. By setting it in the dull state, it becomes possible to pull out the tip portion 41 upward. The non-woven fabric 40 pulled out from the roll 4 is inserted into the insertion hole 51a formed in the bottom plate 51, whereby a predetermined range (preferably a range narrower than the width of the first roller 55 and the second roller 57) is obtained. And is pulled out to the outside from between the first roller 55 and the second roller 57 in a state of being collected to some extent.

Since the first roller 55 and the second roller 57 are pressed against each other by the elastic force of the coil spring 58, the tip end portion 41 is impregnated in the nonwoven fabric 40 by the first roller 55 and the second roller 57. It is pulled out like squeezing out the hot water. While passing through the insertion hole 51a and being sandwiched between the first roller 55 and the second roller 57, the nonwoven fabric has a high tensile strength because it is squeezed finer than the range of the insertion hole 51a. Therefore, the perforations 42 are not separated. When the perforation 42 is pulled out from between the first roller 55 and the second roller 57 and moved upward for a while, the squeezed state of the non-woven fabric 40 is relaxed, so that the hands, the first roller 55 and the second roller 57 are The sheet is cut off at the perforations 42 by not being able to withstand the tension applied between the sheets.

As described above, in the present embodiment, since the hot water can be appropriately squeezed out by the first roller 55 and the second roller 57, the accident that burns due to too much impregnated water is caused. In addition to being able to prevent the above, the pressing force between the first roller 55 and the second roller 57 can be adjusted appropriately, so that the strength for squeezing the hot water and the perforation can be cut at an appropriate position. The necessary pull-out resistance can be easily adjusted, and the optimum pressing force and pull-out resistance can be easily obtained according to the material, thickness, width, perforation size of the hydrous sheet such as nonwoven fabric. .

Further, in the present embodiment, the second roller 57 can be separated from the first roller 55 only by pushing down the moving lever 56, so that even when the roll 4 is set, the tip end portion 41 of the nonwoven fabric is Can be very easily inserted between the first roller 55 and the second roller 57.

Second Embodiment Next, a second embodiment according to the present invention will be described with reference to FIGS. 6 and 7.

In the second embodiment, a bowl-shaped cover 8 is rotatably attached to the upper part of the container 7 by a hinge shaft 70. A semi-circular support plate 71 is integrally provided on the storage container 7, and the support plate 71 abuts on the semi-circular blocking plate 81 integrally provided on the cover 8 so that the storage container 1 and the upper part are supported. The inner space of the cover 8 is partitioned off, and an insertion hole 9 is formed at the center thereof. The edge portion 71a desired for the insertion hole 9 of the support plate 71 and the edge portion 81a desired for the insertion hole 9 of the blocking plate 81 are formed in an arc-shaped cross section so as not to damage the sheet passing therethrough.

A support portion 72 is fixed on the support plate 71, and a first roller 73 is rotatably supported by the support portion 72. The first roller 73 is arranged such that a part of its peripheral surface is located above the insertion hole 9.

On the other hand, an opening lid 82 is provided on the upper surface of the cover 8 so as to be openable and closable. When the cover 8 is molded of synthetic resin, the opening lid 82 can be opened and closed by thinning the root portion and making the root portion easily bendable.

A support portion 83 is provided inside the cover 8, and a bell-rank operation lever 84 is rotatably attached to the support portion 83. A second roller 85 is rotatably supported at one end of the operating lever 84.

An adjustment dial 86 is attached to the cover 8 so as to project above the upper surface of the cover 8 and the shaft portion thereof is introduced into the cover 8 through a through hole formed in the cover 8, and the other end of the operating lever 84 is attached. Is fixed to the tip of the shaft portion of the adjustment dial 86. The shaft portion of the adjustment dial 86 is screwed into a nut 87 arranged outside the through hole of the cover 8.

A coil spring 88 is arranged inside the cover 8 around the shaft of the adjustment dial 86. The coil spring 88 is elastically mounted between the inner surface of the cover 8 and the other end of the operating lever 84 in a compressed state. The second roller 85 is always biased toward the first roller 73 by the coil spring 88.

When the adjusting dial 86 is screwed into the nut 87 and the screwing is deepened, the second roller 85 approaches or comes into contact with the first roller 73 by the operating lever 84, and when the screwing of the adjusting dial 86 is made shallow, the reverse movement occurs. The second roller 85 is separated from the first roller 73. In this way, the rotation of the adjustment dial 86 can adjust the distance between the first roller 73 and the second roller 85. Therefore, it is possible to change the pull-out resistance of the sheet of non-woven fabric or the like by rotating the adjusting dial 86 in the same manner as in the first embodiment.

The pressing force of the second roller 85 toward the first roller 73 causes the elastic region of the coil spring 88 to include the adjustment range of the adjustment dial 86, thereby rotating the adjustment dial 86. You can always make it almost constant.

Since the nut 87 screwed to the adjustment dial 86 is not fixed to the cover 8, the adjustment dial 86 can be pulled upward, and as a result, the second roller 85 is forced. It can be separated from the first roller 73.

FIG. 7 shows a state in which the cover 8 is rotated to open the container 7 in this embodiment. When the cover 8 is opened, the blocking plate 81 also rotates upward together with the cover 8 and a large opening appears in the storage container 7, and the second roller 85 also rotates upward. growing. Therefore, it becomes easy to pull out the tip portion 41 of the non-woven fabric 40 housed in the housing container 7 to the position above the first roller 73, and by closing the cover 8 in this state, the non-woven fabric 40 can be easily transferred to the first roller 7 3 and the second roller 85.

In the first and second embodiments, a lid is further provided above the pair of rollers. Instead of such a lid, a cross like a conventional wet sheet take-out container is used. A cover plate with a star-shaped or star-shaped outlet may be attached.

In addition, in the second embodiment, the second roller connected to the adjusting dial is attached to the cover, but conversely, the first roller is attached to the cover and the second roller is attached to the container. Good.
