Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a hand-wiping device.

(Prior Art) As a hand-wiping device, a long rolled sheet material for hand-wiping is suspended and held in a U shape, and in most cases, an unused portion is pulled out manually and a used portion is stored. Used and recycled used products, paper or non-woven hand wipes that have been cut to a fixed size and set in a container in advance, used and discarded, and delivered with warm air A type that dries water on the surface of the hand is used.

(Problems to be solved by the invention) In a hand-wiping device using a roll-wound long hand-wiping sheet, the sheet surface is usually parallel to the front of the device (usually the device mounting wall surface) as seen by the person trying to wipe his / her hand. Since it is perpendicular to the palm, it is difficult to perform a hand-wiping operation, and the sheet is hung in a U-shape and is usually ironed or the fabric is hardened by repeated use, so that the bottom end of the towel rack is Compared to a towel hung in a free state, it is more difficult to apply the sheet to wrap it around the hand and wipe it. Further, in this type of device, when a nonwoven fabric or the like is used as a sheet, its strength is insufficient, so that the sheet is cut when it is pulled out by hand.

In addition, disposable paper or non-woven hand towels are limited in the number of paper or non-woven hand wipes that can be set in a specified container, so it is necessary to frequently perform replenishment work, and the number of sheets used at one time is limited. There is a problem that it is unspecified, and used items that become bulky after use are discarded on the spot each time and scattered outside the storage box to contaminate the site.

The apparatus for drying with warm air has an advantage in hygiene, but it has a long use time for drying, and there is a problem that the user feels irritated.

(Means for Solving the Problems) The present invention has developed a device that satisfies each of the problems of the above-mentioned hand-wiping device, and particularly improves the hand-wiping operability in the hand-wiping device using a roll-wound long sheet. In a hand-wiping device having a mechanism for winding up a used sheet by sending a sheet out of an unused roll and hanging it downward in a U-shape, the drooping surface of the sheet is substantially perpendicular to the front of the device. It is arranged so that it is in the direction, and a sensor that detects the presence or absence of the hand of the hand wipe part,
The hand-wiping device is provided with a drive mechanism for an unused-sheet feeding roller and a used-sheet winding roller that are activated by a hand-release detection signal of the sensor after hand-wiping.

Embodiments of the present invention will be described below with reference to the drawings. In the apparatus shown in FIG. 1, reference numeral 91 is a main body box, which has a seat hanging window (described later) at least in the lower part, and has the following mechanism. An unused roll 11 formed by rolling a band-shaped sheet material for hand-wiping is rotatably held by a holder 12, and the sheet material 13 is guided by delivery rollers 21 and 22 and drooped in a U shape.
81 is formed, and is further wound around a collecting roller 42 by a winding roller 41 through a plurality of guides 31 for correcting wrinkles, scrapes, etc. of a used sheet.

In this structure, first, the unused roll holder 12,
The feeding rollers 21, 22, the guide 31, the winding roller 41, etc. are all set almost vertically to the front surface of the apparatus (wall surface for mounting the apparatus), and the sheet material 13 guided by these is similarly guided vertically to the front surface of the apparatus. , Especially the hand wipe
The sheet material surface of 81 is hung so as to be perpendicular to the front surface of the apparatus. The surface of this sheet is parallel to the palm of a hand when wiping normally. The delivery roller 21 and the winding roller 41 are interlocked with each other, and preferably have a mechanism for rotating with a single motor 51 so as to wind up a used sheet having the same length as the unused sheet length sent out to the hand-wiping section as a collecting roll.

In addition, this device is equipped with a sensor 61 that detects the presence or absence of a hand on the hand-wiping part, detects the presence of the hand during the hand-wiping operation, and when detecting the removal of the hand after hand-wiping, the motor is activated by a time switch or the like. The delivery roller 21,
22 and the winding roller 41 are rotated for a certain period of time to replace the sheet of the used hand-wipe portion 81 with an unused sheet and prepare a hand-wipe portion of the unused sheet for the next use. This mechanism can be appropriately selected from those generally known. For example, the sensor is not limited to a general optical sensor that is sensitive to visible light, but may be of any type as long as it is equipped with far infrared rays, electromagnetic rays, and other means for sensing the insertion of the hand into the hanging part of the hand-wiping sheet material. . Further, it is also preferable to combine a sensor with a filter circuit or the like for the purpose of preventing malfunctions due to the shaking of the seat due to wind or the like, and the temporary detachment of the hand during hand wiping.

In the present invention, it is more preferable to provide the warm air blower 71 to the hand-wiping part. In this air blower, when the hand is inserted into the hand-wiping portion 81, the sensor 61 responds to actuate the air blower 71, and hot air is blown to the hand being wiped. The operation of the air blower is normally performed until the hand is wiped away. By the warm air blower by this warm air blower, the hand-wiping time is shortened and the hygienic effect is high.

FIG. 2 shows another embodiment of the present invention, in which sheet feeding rollers 21 and 22 are further provided with a third feeding roller.
By combining 23, the rollers 21, 23 and the winding roller 41 are interlocked, and a sheet having the same length as the length to be sent out to the hand-wiping section by the rollers 21 and 22 is fed from the hand-wiping section to the winding roller 41 by the rollers 22 and 23. Have. In this case, the guide 31 is unnecessary.

It should be noted that the rollers 21 and 23 in the present invention are preferably those on which the surface is engraved with a lowlet or a groove, and the roller 22 is an elastic roll of rubber or the like so that the sheet can be reliably fed.
The guide 31 is a rod or a roller.

Further, as the hand-wiping sheet, a non-woven sheet is used in addition to the conventional cloth-made sheet.

(Operation) According to the structure of the present invention, the hand-wiping sheet is guided almost perpendicularly to the front surface (mounting wall surface) of the device and is held by the hand-wiping portion in parallel with the palm for normal hand-wiping. Moreover, due to the action of the sensor, the used sheet after the hand-wiping is automatically replaced with the unused sheet and is always ready for use. Also, due to the action of the same sensor, warm air is sent to this part when hand-wiping.

(Effect of the device) According to the device of the present invention, the sheet material for hand-wiping is held in parallel with the palm and in a hanging state in accordance with the hand-wiping operation of the hand. It is easy and has a high effect of wiping off water. In addition, an unused sheet is automatically prepared in the hand-wiping section, and it is not necessary to pull out the sheet after use, and therefore inexpensive non-woven fabric or the like can be used as the hand-wiping sheet. The sheet can be reused after washing, but it can also be disposable.
