Social welfare facilities such as nursing homes are obliged to use flameproofing products for curtains and carpets to prevent fires. On the other hand, bedding such as sheets is not obligatory, but it is preferable to use a flameproof processed product as with curtains. However, since the sheets of fiber products that have been subjected to a flameproofing process are relatively expensive, it has been difficult to actually purchase and use them in social welfare facilities.

  In social welfare facilities, there are many cases of renting with laundry services instead of purchasing sheets. However, the sheet of the flameproof processed product cannot be handled by an ordinary laundry apparatus as disclosed in Patent Document 1, and a special method and apparatus as described in Patent Document 2 must be introduced. Therefore, the number of linen suppliers who handle sheets of flameproofing products is very limited and the cost is high. Therefore, it was difficult for social welfare facilities to rent sheets of flameproofing products.

  In recent years, in addition to sheets provided with flameproofness, there has been an increasing demand for sheets provided with functions such as fragrance, and a technology capable of easily meeting these demands has been demanded.

  The present invention has been made in view of the above-described background art, and provides a laundry apparatus that can give various functions to a sheet and can be easily manufactured by modifying a part of an existing facility. Objective.

The present invention includes a tension spreader that stretches and spreads a sheet after washing, an ironing apparatus that irons the sheet transported from the tension spreader with a heated press, and the tension spreader and the ironing apparatus. A sheet conveyor for moving the sheets between , and a spraying device for spraying a functional liquid toward the sheets moving on the carry conveyor, the belt of the carry conveyor having a mesh structure Device .

The functional liquid is, for example, a liquid for flameproofing or aroma treatment.

  The laundry apparatus of the present invention is an apparatus particularly suitable for use in linen service, and can be manufactured at a low cost by attaching a predetermined spraying apparatus to an existing facility. In addition, since sheets are frequently washed, the functions (flameproofing, aromaticity, etc.) imparted to the sheets need only be maintained for a predetermined short period. Therefore, by adjusting the concentration of the functional liquid, the amount of spraying by the spraying device, the pressing pressure and heating temperature of the ironing device, etc. for each type of functional liquid, the necessary and sufficient functions can be efficiently performed for normal sheets. It can be given well at low cost.

It is a schematic front view which shows one Embodiment of the laundry apparatus for sheets of this invention.

  Hereinafter, an embodiment of a laundry apparatus for sheets according to the present invention will be described. The laundry apparatus 10 according to this embodiment is an apparatus for a normal sheet S that is not a flameproof processed product or the like, and includes a laundry dehydrator 12, a dryer 14, a spreader 16, a spraying device 18, an ironing device 20, and It comprises a folding machine 22 and, as shown in FIG.

  First, the used sheets S are put into the washing / dehydrating machine 12, washed and dehydrated, and then put into the drying machine 14. Then, the sheet S that has been semi-dried by the dryer 14 is put into the spreader 16, spread out, and carried out from the carry-out conveyor 16a.

The spraying device 18 is a device that sprays the functional liquid 18a toward the sheet S that moves on the carry-out conveyor 16a, and is attached to the outer surface of the spreader 16 above the carry-out conveyor 16a. The functional liquid 18a is, for example, a commercially available solution such as a flameproofing agent or a fragrance. The carry-out conveyor 16a has a mesh-structured belt .

  The sheet S supplied with the functional liquid 18a is put into the ironing device 20 and ironed. The ironing apparatus 20 includes a carry-in conveyor 20a for carrying the sheet S, a press machine 24 (for example, a roll ironer) for pressing and drying the sheet S between the heated roll 24a and the chest 24b, and a carry-out conveyor for carrying the sheet S. 20b. The flameproofing agent and the fragrance treating agent in the functional liquid 18 a are fixed to the sheet S by being ironed by the press machine 24. Then, the processed sheet S is unloaded from the unloading conveyor 22a in a stretched state.

  Thereafter, the sheet S is put into the folding machine 22 through the carry-in conveyor 22a and carried out in a folded state.

  The concentration of the functional liquid 18a, the spray amount by the spraying device 18, the setting of the press pressure and heating temperature of the press machine 24, and the like are appropriately adjusted according to the type of the functional liquid 18a. If the functional liquid 18a is too thick or has a too much spray amount, problems such as easy attachment of sheets to the press machine 24 are likely to occur, but the spray amount by the spray device 18 should be easily adjusted. Can do.

  As described above, the sheet laundry machine 10 according to the present invention has the spraying device 18 attached to the existing equipment (the washing and dehydrating machine 12, the dryer 14, the spreader 16, the ironing device 20, and the folding machine 22). It can be manufactured inexpensively. As a method of supplying the functional liquid 18a to the sheet S after washing, for example, a method of immersing the sheet S in the functional liquid 18a is conceivable, but it is difficult to configure as a continuous device, and the workability is very high. Unfortunately, the functional liquid 18a adhering to the dehydrated sheet S must be dehydrated again and managed to an appropriate amount of adhesion, which is troublesome. On the other hand, by using the spraying device 18, an appropriate amount of the functional liquid 18a can be efficiently supplied to the sheet S.

In addition, since the sheets S are frequently washed, the functions (flameproofing, fragrance, etc.) imparted to the sheets S only need to be maintained for a predetermined short period. Therefore, it is necessary for ordinary sheets S by appropriately adjusting the concentration of the functional liquid 18a, the spray amount by the spraying device 18, the press pressure and the heating temperature of the press machine 24 for each type of the functional liquid 18a. Sufficient functions can be efficiently and inexpensively provided. For example, the flameproofing product sheets are flameproof have been manufactured to be maintained for a long period of time, but is not good feel hard and, by the use of laundry apparatus 10, feeling closer to normal sheets The flameproof sheets can be provided.

In addition, the laundry apparatus for sheets of the present invention is not limited to the above embodiment. For example, the functional liquid 18a may be sprayed on the sheet S moving on the carry-out conveyor 16a between the spreader 16 and the ironing device 20 . Therefore, the spraying device 18 for spraying the functional liquid 18a may be provided integrally with the spreader 16 as described above, or may be provided integrally with the ironing device 20 . Or if there is room in the installation space of the laundry device , the spraying device may be installed separately from the spreader and ironing device .

  The ironing device is not limited to the configuration of the roll iron as described above. In addition, the specific configurations of the laundry dehydrator, the dryer, and the folder are not particularly limited, and can be selectively omitted.

  As described above, as the functional liquid, a liquid for flameproofing or aroma treatment is suitable, and many demands are expected for sheets. In addition to this, a liquid imparting other functions may be used as long as it can be fixed by ironing.
