Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supply device for paper towels used for various household and commercial cleaning purposes, and more specifically, it is installed in a kitchen, washroom, living room, etc.
The present invention relates to a supply device for paper towels which is automatically supplied in a wet state or a dry state in which paper towels of a required length made of paper or non-woven fabric used for cleaning kitchen equipment, dishes and the like and for face washing are selectively supplied.

[0002]

2. Description of the Related Art As a wet tissue device which is generally commercially available, a roll-shaped paper or non-woven fabric with perforations, which has been previously moistened, is contained in a cylindrical container with a lid. The paper or non-woven fabric is pulled out from the inside of the container, and there are those that cut along the perforations due to the resistance at that time, or in a wet state,
In some cases, paper or non-woven fabric cut into a length to be used in advance is stacked in a box-shaped storage container in a folded state, and the paper or non-woven fabric is taken out one by one each time it is used. However, in such a commercially available wet tissue device, the paper or non-woven fabric contained in the container is easily dried, and is not suitable for long-term storage. Further, in the structure in which the wet paper rolled up in a roll in the container is sequentially taken out from the small outlet formed in the center of the container lid to prevent drying, the outlet is extremely narrow. Therefore, it was difficult to take out the wet paper.

In view of these points, a paper towel supply device for automatically supplying paper towels of a required length in a wet state or a dry state with each use is disclosed in, for example, Japanese Patent Laid-Open No. 64-80326. It is disclosed. According to the paper towel supply device disclosed in this publication, when a paper towel in a wet state is used, a pair of feeding rollers for driving the roll paper towel rotatably supported by the support portion to rotate. It is a device that is used by cutting the paper towel by cutting it to a predetermined length at the cutting part by contacting it with the wetting roller moistened by the moistening part and actively feeding it out by the cutting part. When used in, the roller moving part is operated to separate the wetting roller from the wetting part or the paper towels and feed out the paper towels.

[0004]

By the way, the above-mentioned moisturizing section constantly supplies the water in the water supply tank to the jelly-like or sponge-like water retaining material filled in the moistening case through the water guiding pipe. Since the water-retaining material in the wet part is always in a wet state because it is wet, it is necessary to operate the roller moving part to separate the wet roller from the water-retaining material when the paper towels are used in a dry state. Become. Therefore, not only the internal mechanism becomes complicated, but when you want to use dry paper towels, the part that is first fed out is in a wet state, and after using it in a dry state, try to use it in a wet state. Then, similarly, the portion that is first fed out is in a dry state, and in any case, the portion to be discarded is increased and the consumption amount of paper towels is increased.

The present invention has been made to solve such a problem, and its purpose is to provide a simple and rational mechanism for automatically and reliably controlling the wet and dry states of paper towels. An object of the present invention is to provide a paper towel supply device that can be switched to.

[0006]

In order to achieve the above object, the present invention provides a liquid tank which is replaceably mounted in a casing having a paper towel drawer opening on the front side, and is connected to the liquid tank via an opening / closing valve. And a liquid applying means extending in the width direction in the casing, at least one porous elastic roll provided in opposition to the liquid applying part of the liquid applying means, and a towel feeding part driven and rotated by the driving means. In a device for supplying paper towels, the upper surface of the casing is configured as a mounting surface of the liquid tank, and the mounting surface has an opening communicating with the liquid applying unit via the valve and the pipe. And a liquid tank, the liquid tank is a placed open-type liquid tank having a siphon valve. It has been a cornerstone configuration.

Further, according to a preferred embodiment, the front surface of the casing is constituted by a front-closing type opening / closing door, and the opening / closing door supports a paper towel supply unit for supporting paper towels in a roll shape or an alternating folding shape, and a paper towel type. It has a part or all of the cutting means for cutting in the width direction and a guide member for guiding the paper towels between the paper towel supply part and the outlet of the paper towels, and the cutting means has the porous elasticity. An operating lever, which is arranged between the roll and the towels feeding section, and whose operating end projects outside through a slit formed in the width direction of the opening / closing door, and a rotary cutting attached to the tip of the operating lever. A blade, a guide member for slidingly guiding the tip portion in the width direction of the opening / closing door, and a paper within the moving range of the rotary cutting blade in the casing. And a backup material relative to bridged by paper towel such in the rotating cutting blade to the cutting site Ol class. This cutting means is disposed between the porous elastic roll and the towels feeding section, and a rotary cutting blade controlled and driven in the width direction of the opening / closing door by a driving source,
A guide member that guides the rotary cutting blade in the width direction of the casing, and a backup material for the paper towels that is erected within the moving range of the rotary cutting blade in the casing and at the cutting site of the paper towels relative to the rotary cutting blade. It may be configured by an automatic cutting device having and.

Further, the liquid applying section of the liquid applying means is
The tray is extended in the width direction of the casing, and has a tray shape having an opening continuous in the length direction of the width center portion,
The tray-shaped bottom surface is arranged so as to come into contact with the porous elastic roll from below, and the porous elastic roll and the towels feeding portion are arranged such that the porous elastic roll has a predetermined rotation angle after the cutting means is operated. It has a control means for independently controlling and rotating to wipe the liquid adhered to each surface of the porous elastic roll and the liquid applying part by the rest of the towels, and sending out the paper towels necessary for use to the outlet. ing. The valve is an electromagnetic valve, and the opening operation is stopped by a closing signal from the outside.

[0009]

When the liquid contained in the liquid tank is empty, the siphon valve is automatically closed when the liquid tank is taken out from the tank mounting surface on the upper surface of the casing. The valve is placed on the upper surface, and then the valve is removed from the liquid tank to fill the liquid. After reattaching the siphon valve, the liquid tank is inverted so that the valve is on the lower side and set on the tank mounting surface. At this time, the valve stem of the valve comes into contact with a part of the mounting surface and is pushed up, and the valve is opened so that the liquid inside can flow down to the liquid storage part formed on the mounting surface.

When the roll towels are used up and replenished, the opening / closing door on the front surface of the casing is opened by tilting it forward, and new roll towels are placed and supported on the roll towel supporting portion on the upper surface thereof. After that, roll towels are replenished by a simple operation of closing the door.

An example of the operation of the device of the present invention will be explained. For example, when it is desired to use paper towels in a wet state, the switch for wetting is pressed to operate the porous elastic roll and the feed portion and at the same time the open / close valve is opened. The paper towels whose tip is in the cutting position are fed between the porous elastic roll and the tray-shaped body by the operation of the feed part, and the liquid overflowing from the opening when passing through the opening of the tray-shaped body is the same. The towels are impregnated to wet them. When the paper towels are sent out for a predetermined length and the cutting portion reaches the operating position of the rotary cutting blade, the driving of the porous elastic roll and the feed portion is stopped. Here, the cutting means is operated to cut the paper towels in the width direction by the rotary cutting blade. When this cutting is completed, for example, a micro switch or the like operates, and only the porous elastic roll starts to operate independently. The operation at this time is
This corresponds to a feeding amount sufficient to pull out the rear end portion of the paper towels separated by cutting the porous elastic roll from the outlet. Further, as the cutting means, it is also possible to perform automatic cutting in which the rotary cutting blade is automatically operated in association with the stoppage of the supply of towels by the switch operation.

When the user wants to use the paper towels in a dry state, pressing the drying switch starts driving the porous elastic roll and the feed section, but the open / close valve remains closed and the liquid applying section keeps operating. No new liquid is supplied to the opening. Moreover, even if the towels in a wet state as described above were used last time and the switch was pressed immediately after that, the liquid remaining on the surface of the porous elastic roll and the opening of the tray-shaped main body was not removed. Is wiped off by the towels sent out at the final rotation of and the liquid level of the opening sinks into the inside of the liquid widening part by the absorbed amount, so it is newly sent between the porous elastic roll and the opening. Almost no liquid adheres to the towels, and the towels are sent out from the outlet in a dry state. The operating procedure in each of the other parts is the same as when supplying wet towels.

In the illustrated embodiment, the casing 2 has a substantially rectangular parallelepiped shape, and a take-out port 21 for towels is formed at the lower end of the front face thereof. The opening / closing door 22 is hinged and is rotatable about the hinge portion at a predetermined angle. According to the illustrated example, the opening / closing door 22 has a substantially inverted triangular side wall 23 extending from the left and right side edges thereof into the casing, and has an arc guide surface at an upper portion of the left and right side wall 23. A support portion 24 for the roll towels 1a is formed.
Now, when the roll towels 1a are used up and replenished,
The opening / closing door 22 is opened by tilting it forward, and a new roll towel 1 is attached to the roll towel support 24 on the upper surface thereof.
After mounting and supporting a, the roll towels 1a can be replenished by a simple operation of closing the door 22. Further, a support plate 25 is provided at the rear end edge of the support portion 24 so as to extend toward the paper towel take-out port 21, and the support plate 25 provides a pressing plate 26 for the paper towel 1 via a spring 25a. Have Further, according to the illustrated example, the bottom surface of the casing 2 is released, and the drip pan 27 is detachably attached to the bottom of the casing 2 by an ordinary attachment / detachment mechanism.

A slit 28 extending in the width direction is formed at a substantially central portion of the opening / closing door 22, and a cutting operation lever 91 for the paper towel 1 is passed through the slit 28 to cut the paper towel 1. 9 are installed. The slit 28 is provided in the cutting means 9 according to the illustrated example.
A cutting mechanism that is activated by moving the cutting operation lever 91 to the left or right is adopted. That is, the operation knob 91a is attached to the outer end of the cutting operation lever 91, and the cutting blade support bracket 92 is fixed to the inner end of the lever 91 at a predetermined angle. The cutting blade support bracket 92 has a cutting blade support portion 92a at the lower end, and the cutting blade support portion 92a rotatably supports the rotary cutting blade 93 so as to traverse the supply path of the paper towel 1 while rotating. is doing. A backup plate 94 made of a synthetic resin is laid on the casing 2 at an opposing portion sandwiching the paper towel 1 along the moving path of the rotary cutting blade 93.

The cutting means 9 is not limited to the manual operation as described above. For example, various operating switches are prepared on the front surface of the casing 2 as shown in FIG. 2, and the disconnecting switch is turned on. Then, the bracket 92 can be configured to be controlled and driven along the backup plate 94 by, for example, a chain drive (not shown). These manual or automatic driving mechanisms may be used alone or in combination with both of them.

The upper surface of the casing 2 serves as a tank mounting surface 29 on which the liquid tank 3 is mounted and supported. A siphon valve 4 is detachably attached to a part of the bottom portion 31 of the liquid tank 3,
The siphon valve 4 is slidably and liquid-tightly inserted into the main body 41 and has a valve rod 43 which is always urged outward by a spring 42. The valve seat 44 fixed to the inner end is elastically contacted with the valve seat surface 41a of the main body 41 from the inside. On the other hand, when the liquid tank 3 is mounted, the tank mounting surface 29 of the casing 2 is the same because the valve rod 43 protruding from the on-off valve 4 presses a part of the tank mounting surface 29 and is pushed back. Valve rod 43
Contracts the spring 42 to move the valve seat 44 to the valve seat surface 41.
It has a valve rod contact surface 29a which is separated from a, and a liquid storage portion 29b for storing the liquid flowing down from the liquid tank 3. The liquid storage portion 29b is a liquid spreading portion of the liquid applying portion 51 described later. It communicates with the width portion 51b through a pipe 52.
When the liquid stored in the liquid tank 3 becomes empty, the siphon valve 4 is removed from the liquid tank 3 to fill the liquid, and the valve 4 is directed downward and the handle is turned up to the tank of the casing 2. When mounted on the mounting surface 29, the valve rod 43 is pushed up by the valve rod contact surface 21b to open the valve and allow the liquid inside to flow down to the liquid storage portion 29b.

In the present embodiment, the pipe 52 hangs along the vicinity of the inner wall surface of the back portion of the casing 2, is bent forward at a right angle above the drip pan 27 and extends horizontally, and is opened / closed with the opening / closing valve 53. The tip is connected to the liquid application unit 51 via the valve 54. The overall shape of the liquid applying portion 51 is a tray-shaped main body 51 a extending over substantially the entire width direction of the casing 2 and the main body 51.
a liquid widening portion 51b continuously provided on the bottom rear surface of a, and the inner surface of the main body 51a forms an arc surface 51c that abuts over the entire circumference of the porous elastic roll 6. Further, at the center of the circular arc surface 51c, there is a slit-shaped opening 51d that also opens to almost the entire width of the porous elastic roll 6, and the opening 51d is located inside the liquid widening portion 51b. It is in communication. Further, it is desirable that the surface of the tray-shaped main body 51a is coated with, for example, a fluororesin.

The porous elastic roll 6 has a casing 2
It is arranged so that a part of its peripheral surface is exposed to the outside from the take-out port 21 of the paper towel 1 and is controlled and rotated via the belt 13 by the drive of the first electric motor 12. The liquid applying portion main body 5 is attached to the porous elastic roll 6.
The slit-shaped opening 51d of 1a is in sliding contact from below, and when the liquid is sent to the liquid widening part 51b through the pipe 52, it overflows from the opening 51d, and the porous elastic roll 6 and the main body 51a. The paper towels 1 sandwiched between the circular arc surface 51c and sent out are wetted by impregnating the same liquid over the entire width. On the other hand, the towel running surface of the backup plate 94 of the cutting means 9 and the liquid applying part 5
A feed portion 8 of the paper towel 1 having a towel supply surface is provided at a portion including the towel inlet of the tray-shaped main body 51a of No. 1 and facing the pressing plate 26 of the paper towel 1. The feed unit 8 controls and drives the supply belt 81 stretched along the supply surface of the paper towels 1, a belt drive roll 82 and a support guide roll 83 that drive the belt 81, and the belt drive roll 82. The second electric motor 83 is provided.

The timing control in the porous elastic roll 6 and the feed section 8 is carried out, for example, when the porous elastic roll 6 and the feed section 8 are operated, and the paper towels 1 of the length to be used are discharged to the outlet 21. When sent out,
Then, the driving of the porous elastic roll 6 and the feed section 8 is temporarily stopped. When the cutting means 9 is operated to cut the paper towel 1, the porous elastic roll 6 independently rotates the predetermined rotation angle to send the cut paper towel 1 from the outlet 21.

In the above-mentioned embodiment, the porous elastic roll 6 and the drive roll 82 of the feed section 8 are driven independently by the dedicated first and second electric motors 12 and 83 respectively. The porous elastic roll 6 and the feed unit 8 are connected to the same drive source through an appropriate transmission mechanism such as a timing belt, and an electromagnetic clutch or the like is interposed therebetween, and the above-described sequence command is issued from a microcomputer control unit (not shown). It is also possible to control the timing and rotation of the.

Further, in this embodiment, an electromagnetic valve is used as the opening / closing valve 53 provided in the liquid flow path of the pipe 52, and the casing 2 as shown in FIG.
Is connected to a wetting / drying switch mounted on the front surface of the switch, and the switch valve 53 is opened and closed by selectively turning on the switch. That is, when the wetting switch is turned on, the opening / closing valve 53 opens and the liquid is sent from the liquid tank 3 to the liquid applying unit 51 through the pipe 52. At the same time, the porous elastic roll 6 and the feed part 8 are actuated to send out the paper towels 1 having a predetermined length to the outlet 21. At this time, the towel 1 has a tray-shaped main body 51.
The slit-shaped opening 51d of a is sent out toward the outlet 21 while being elastically contacted by the porous elastic roll 6, and the liquid overflowing from the slit-shaped opening 51d impregnates the paper towels 1 to Moisten. The opening / closing valve 53 is automatically closed immediately before the wet towels 1 of the used length are sent out from the outlet 21 according to the procedure described later. When the opening / closing valve 53 is closed, the porous elastic roll 6 makes one rotation, and when the liquid on the surfaces of the tray-shaped main body 51a and the slit-shaped opening 51d is wiped off, the liquid level of the opening 51d spreads. It sinks inside the width portion 51b.

When the drying switch is turned on, the porous elastic roll 6 and the feed portion 8 start to operate, but the opening / closing valve 53 is kept in the locked state, so that the liquid is stored in the tray-shaped main body 51a. Paper towels 1 that do not overflow from the opening 51d and are sent out between the porous elastic roll 6 in a dry state and the tray-shaped main body 51a
Is not wet and is supplied from the outlet 21 in a dry state. At this time, in order to prevent liquid from remaining on the surface of the porous elastic roll 6, at least the surface of the roll 6 is made of a porous elastic material composed of closed cells, and the surface of the roll 6 is wiped off made of a hygroscopic material. The material 14 is brought into sliding contact. When a predetermined time has passed after the paper towels 1 having a length required for use were sent out, the lock state of the opening / closing valve 53 is automatically released.

Next, a typical example of the operation procedure of the paper towel supply device 1 of the present invention constructed as above will be described in detail. Note that the following operation procedure is merely an example, and the operation procedure and control drive of the operation member of each part can be variously changed.

Now, for example, when it is desired to use the paper towels 1 in a wet state, the switch for wetting is pressed to operate the porous elastic roll 6 and the feed section 8 and at the same time the open / close valve 53 is opened. The paper towel 1 whose tip is placed at the cutting position is fed between the porous elastic roll 6 and the tray-shaped main body 51a by the operation of the feed section 8 and is opened when passing through the opening 51d of the tray-shaped main body 51a. The liquid overflowing from the portion 51d impregnates the towel 1 and wets the towel 1. Paper towels 1
Is sent out for a predetermined length, and when the cutting position reaches the operating position of the rotary cutting blade 93, the driving of the porous elastic roll 6 and the feed portion 8 is stopped. Here, the operating lever 9
When 1 is moved to the left or right, the rotary cutting blade 93 pivotally supported by the tip of the lever 91 via the support bracket 92 rolls while pressing the surface of the paper towels 1 supported by the backup material 94. The towels 1 are moved and cut in the width direction. When this cutting is completed, for example, a micro switch (not shown) operates and only the porous elastic roll 6 starts to operate independently. The operation at this time is a rotation amount corresponding to a feed amount sufficient to pull out the rear end portion of the paper towel 1 cut by cutting the porous elastic roll 6 from the outlet 21. In this embodiment,
Towel inlet of the tray-shaped main body 51a and the rotary cutting blade 9
It is set so that the distance from the cut portion by 3 is equal to one rotation amount (circumferential length) of the porous elastic roll 6. Further, in this example, the case where the cutting means 9 is manually operated is illustrated, but as described above, it is possible to automatically cut the towels 1 in conjunction with the stop of the supply of the towels 1 only by operating the switch. It is also possible to configure.

On the other hand, when it is desired to use the paper towels 1 in a dry state, pressing the drying switch starts driving the porous elastic roll 6 and the feed section 8, but the open / close valve 53 remains closed. , Tray-shaped main body 51a
No new liquid is supplied to the opening 51d of the. In addition, even if the towel 1 in the wet state as described above is used last time, the liquid remaining on the surface of the porous elastic roll 6 and the opening 51d of the tray-shaped main body 51a is the final rotation of the porous elastic roll 6. At the same time, the towels 1 are sent out and wiped off at the same time, and the liquid surface of the opening portion 51d also has the liquid widening portion 5
Since it sinks into the inside of 1b, almost no liquid adheres to the towels 1 newly fed between the porous elastic roll 6 and the opening 51d, and the towel 1 is sent out from the outlet 21 in a dry state. The operation procedure in each of the other parts is the same as that when the wet towels 1 are supplied.

In the above example, the delivery length of the towel 1 is set in advance and the driving of the porous elastic roll 6 and the feed section 8 is automatically controlled. As long as one of the drying / drying switch is kept pressed, the paper towel 1 can be continuously fed out, so that the length required by the user can be freely selected. Of course, in this case as well, both manual and automatic cutting means can be adopted, but in the automatic case, the rotary cutting blade 93 is configured to operate only when the cutting switch is pressed.

[0028]

As is apparent from the above description, according to the paper towel supply apparatus of the present invention, the liquid tank is the inverted type having the siphon valve, so that the replenishing operation of the application liquid can be easily performed and the tank can be refilled. The tray-shaped liquid application section communicating with the liquid is overflowed from a long hole opened on the upper surface, and the liquid is applied to the paper towels sent between the liquid application section and the porous elastic roll. Since the supply of the liquid to the applying portion can be reliably stopped by closing the opening / closing valve by the switch operation, the paper towels of the required length can be automatically supplied in the wet or dry state by a simple selection operation. Further, in the present invention, since the opening of the liquid applying part is a long hole continuous in the width direction of the paper towels, the wetting of the paper towels is more uniform than in the case where the liquid applying part is configured by arranging a number of jet nozzles in parallel. After each further wetting operation, the periphery of the opening and the surface of the porous elastic roll are wiped off by the trailing end portion of the towels sent out, so that the drying is performed immediately after the wetting operation. Even when towels are used, the towels delivered are almost completely dry.
