DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized towel manufacturing apparatus capable of manufacturing a folded disposable towel at a place of use.

[0002]

2. Description of the Related Art Recently, a trader or the like has provided a sheet roll obtained by winding a sheet material which is a towel material such as paper or nonwoven fabric into a roll so as to be able to be fed out, and water such as a chemical solution for moistening the sheet material. 2. Description of the Related Art A small towel manufacturing apparatus that can manufacture a required amount of disposable towels when necessary at a place where a user of a restaurant or a company uses the same in a restaurant or a company has begun to spread. Because it is convenient to manufacture the required amount of disposable towels when and where it is needed, and because there is no storage period like a towel provided by a supplier, it is clean and very convenient without worrying about mold and drying. It is expected to spread.

[0003] A small towel manufacturing apparatus of this kind, in which a required amount of towel is manufactured by a user at a place where the sheet is used, includes a roll-shaped sheet material which is a towel material such as paper or nonwoven fabric. Equipped with a water tank containing water for applying moisture to the sheet material fed from the sheet roll and the sheet material fed from the sheet roll,
Cutting means for cutting the sheet material fed from the sheet roll into a unit length as one towel by a cutter, and water supplied from the water tank toward the sheet surface of the sheet material cut into the unit length. A water spraying means for spraying water, and a winding means for winding a sheet material cut to a unit length and sprinkled into a roll, wherein the winding means is a sheet cut to a unit length as a towel and watered. Endless belt for transferring the material, and a fixed belt disposed at a predetermined interval along the transfer surface of the transfer endless belt, and the sheet material is sandwiched between the transfer endless belt and the fixed belt. Is configured so that it is rolled while being conveyed and wound in a roll shape.

[0004] However, the following problems have been pointed out in the conventional towel making apparatus using the above-described watering means, winding means and cutting means. First, the water sprinkling means is configured to spray water supplied from the water tank toward the sheet surface of the sheet material from a plurality of ejection ports formed in the ejection pipe to apply moisture to the sheet material. ,
Moisture is difficult to impregnate evenly between the sheet part where water is directly sprayed and the sheet part where water is not sprayed, and the sheet part which is not directly sprayed takes time to penetrate the water, so the appropriate amount of water is instantaneously and evenly spread over the entire sheet It is difficult to be impregnated, and the water sprinkled toward the sheet surface is liable to be scattered outside the sheet surface, so that excess water remains in the apparatus and must be constantly removed. For this reason, there is a problem that moisture easily accumulates inside the device, bacteria and the like propagate, and water loss increases.

[0005] Further, the towel manufacturing apparatus using the winding means, wherein the sheet material is rolled while being held between the transfer endless belt and the fixed belt while being conveyed in a sandwiched manner, has a habit of a rubber belt and a sheet material. In this case, since the sheet is rolled, the sheet is wound or not wound properly, and the sheet material is caught in the middle of winding, resulting in poor reliability. Further, the towel manufacturing apparatus using the winding means cannot cope with a change in the material of the sheet material or a change in the thickness thereof, so that the towel material is limited. Further, in the towel manufacturing apparatus using the winding means, the winding portion including the transfer endless belt and the fixed belt for rolling the sheet material into a roll occupies a large amount of space in the apparatus. The entire device becomes large, making it difficult to reduce the size of the device, and the amount of sheet rolls and water tanks provided in the device is limited, so that there is a problem that their replacement cycle is shortened. .

Further, the sheet material fed from the sheet roll is cut into a unit length as one towel by a cutter, and the cutting means by the cutter is arranged before the watering means and the winding means. The towel manufacturing apparatus by the cutting means is technically difficult to accurately and reliably transport the sheet cut to the towel unit length to the winding part via the sprinkler part, and, for example, In the case where the cutter device is constituted by a fixed blade and a rotary blade, the cutter device occupies a large amount of space in the device. And the amount of sheet rolls and water tanks provided in the apparatus is limited as in the case of the above-described wrapping section. There is that evil.

[0007]
