Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stain removing method and a stain removing apparatus for use in removing stains adhering to fabrics, and in particular, spraying and suctioning a cleaning agent on a processed material such as fabrics concurrently. The present invention relates to a stain removing method and a stain removing device.

[0002]

2. Description of the Related Art Conventionally, a cloth is placed on a perforated plate such as a punching plate or a wire net, and a cleaning agent is sprayed onto the cloth with a gun, and the space below the cloth is sucked into the cloth and the perforated cloth. There is known a stain removing method and a stain removing device which are arranged to generate an air flow passing through the plate. It has been found that in the stain removing method and the stain removing device by this method, the higher the spraying pressure of the cleaning agent to the soiled portion or the spotted portion of the fabric is, and the stronger the suction force is, the better the stain removing effect can be obtained. . Also,
It has also been found that when the suction force is increased, the cloth to which the cleaning agent is attached dries faster and the occurrence of ring stain is suppressed.

[0003]

By the way, in the conventional stain removing method and stain removing apparatus, when the cleaning agent is linearly jetted at a high pressure by a gun, the fabric may have wide stitches or holes to form the fabric. There was a problem of damaging it. Such a situation tends to occur remarkably when processing thin cloth such as silk. Therefore,
A method of spraying the cleaning agent in a mist form with a gun is sometimes used, but this method does not easily remove stains and stains attached to the processed material, and the cleaning agent scatters to an unnecessary range. Has the drawback that it is easily consumed in vain.

On the other hand, in the conventional stain removing method and stain removing device, when the suction force is strengthened to speed up the drying of the fabric and suppress the generation of ring stain, the fabric is squeezed into many holes of the perforated plate. There is a problem in that the cloth may be bitten to cause a large number of irregularities, or in severe cases, the cloth may be locally torn at the edge of the hole of the perforated plate.

By the way, instead of an organic solvent such as CFC or trichloroethane as a stain remover, an amphoteric water-based alkaline stain remover which can be used for aqueous and oily stains and stains has recently been provided. Since this cleaning agent is water-based, its volatility is lower than that of the above-mentioned organic solvent. Therefore, when the suction force is weak, the processed material to which the cleaning agent adheres is delayed in drying and tends to cause ring stain. Therefore, in the conventional stain removal method and stain removal device that can increase the suction force only in the range where unevenness does not occur on the fabric, the use of the water-based alkaline stain removal cleaning agent accelerates drying and suppresses the occurrence of ring stains. Is limited. Therefore, even if the above-mentioned water-based alkaline stain removing detergent is effective and convenient for both water-based and oil-based stains and stains, there is a problem that the cleaning material is difficult to use.

The present invention has been made in view of the above problems and circumstances, and by increasing the straight injection pressure of a cleaning agent by a gun and at the same time increasing the suction force, it is possible to remove stains and stains attached to a processed material such as cloth. (EN) Provided is a method for removing stains on a cloth or the like which does not cause damage to the processed product due to perforations or irregularities even if the removal efficiency is increased and drying is accelerated to suppress the generation of ring stains. With the goal. Another object of the present invention is to provide a stain removing device for a cloth or the like which can carry out such a stain removing method.

And a stepped recessed receiving portion for supporting the outer peripheral portion of the underlayment is provided at the peripheral edge of the opening of the work table.

According to a third aspect of the present invention, there is provided a stain removing device for a cloth or the like, wherein the perforated plate of the underlaying material and the pad are integrally joined.

According to a fourth aspect of the present invention, there is provided a stain removing device for a cloth or the like according to the second or third aspect, in which the pad of the underlayment is made of raised felt.

[0011]

According to the method for removing stains on a cloth or the like according to the first aspect of the present invention, the cushioning property of the pad of the underlayment absorbs the impact when the cleaning agent collides with the treated material such as the cloth. Further, the above-mentioned pad prevents the processed material such as cloth from invading the hole portion of the perforated plate due to the spray pressure of the cleaning agent and the suction force of the lower space. Further, since the pad serves to absorb the cleaning agent adhering to the object to be treated, it speeds the drying of the cloth and suppresses the occurrence of ring stain.

The stain removal device for a cloth or the like according to the second aspect of the present invention also achieves the above-described operation with respect to the first aspect of the invention.

According to the stain removing device for cloth or the like according to the third aspect of the present invention, since the perforated plate and the pad are integrally joined, the underlaying material can be handled as one member.

It is made of a punching plate with 12 of uniform density. The pad 15 is a fiber assembly having good air permeability, liquid permeability, liquid absorption, and cushioning properties. Here, fiber aggregates include woven fabrics such as gauze and non-woven fabrics such as felt, as well as fibrous layered products in which cotton or the like is laminated to a certain thickness. Among them, felt with a raised surface is used. It can be preferably used as the pad 15. Further, a non-woven fabric such as felt and a woven fabric such as gauze laminated on one side can also be suitably used. The perforated plate 11 and the pad 15 may be independent and separate or may be integrally joined with an adhesive, but when the both are joined, the perforated plate 11
It is desirable to apply an adhesive to the pad and to bond the pad 15 by stacking the adhesive on the pad, so that the air permeability, liquid permeability and liquid absorption of the pad 15 are not easily impaired by the adhesive.
Further, a mesh body having a fine mesh as schematically shown in FIG. 3 may be used for the perforated plate 11 of the underlayment 1, and in that case, the mesh functions as the hole 12. As the net used for the perforated plate 11, it is possible to use a wire net or a net made of synthetic resin in which the wire made of the above-mentioned stainless steel, aluminum, or some kind of alloy is knitted in the length and width directions. In addition,
Although it is desirable that the perforated plate 11 has a property of being hard and difficult to bend, if a member such as a lattice for preventing the perforated plate 11 from bending is provided in the opening 24 of the workbench 2 which will be described later, it is flexible. It may have sex.

The workbench 2 is a hollow body, and an internal space 21 of the workbench 2 as a space below the underlayment 1 is connected to a suction port of the suction mechanism 4 by a hose 22. Further, an opening 24 is provided at an appropriate position on the upper wall portion 23 of the workbench 2, and a stepped recessed receiving portion 25 is provided at the peripheral edge portion of the opening 24.
Is provided. Then, the above-described underlayment material 1 is laterally mounted on the receiving portion 25 with the perforated plate 11 on the lower side and the pad 15 on the upper side. A lock mechanism or the like for fixing the underlayment 1 to the receiving portion 25 may be provided, which is preferable in order to prevent displacement of the underlayment 1 during stain removal work. is there. Further, parts for fluid control such as an on-off valve interposed in the hose 22 are not shown.

By the way, in the underlay material 1, there are the case where the perforated plate 11 and the pad 15 are separate as described above, and the case where both are integrated. In either case, the perforated plate of the underlay material 1 is used. As described above, it is possible to lay the 11 and the pad 15 on the receiving portion 25 so that they can be attached to the opening 24 or can be removed from the opening 24. Needless to say, the present invention includes both the hole plate 11 and the pad 15 that can be attached to and detached from the receiving portion 25. On the other hand, when the perforated plate 11 and the pad 15 are separate bodies, the perforated plate 11 is welded and attached to the receiving portion 25, and the pad 15 can be attached to and detached from the perforated plate 11. It is also possible, and such is also included in the present invention.

Although the gun 3 has a function of directly spraying the cleaning agent, a gun 3 having a function of spraying the cleaning agent in a mist state in addition to the function is also known. Reference numeral 31 is a hose for supplying a cleaning agent to the gun 3, which is led out from a cleaning agent tank (not shown).

Next, a stain removing method according to an embodiment of the present invention will be described.

As shown in FIG. 1, the underlayment 1 is laid horizontally on the receiving portion 25 of the workbench 2 to cover the opening 24, and the cloth 5 is placed on the pad 15 of the underlayment 1, and in that state, the gun The cleaning agent S is sprayed from 3 to spray the cleaning agent S on the cloth 5, and the suction mechanism 4 is operated to operate the internal space 21 of the workbench 2.
Is suctioned to generate an air flow a passing through the cloth 5 and the underlayment 1. In this way, dirt and stains on the cloth 5 are removed by the action of the cleaning agent S sprayed on the cloth 5, and the cleaning agent S attached to the cloth 5 is absorbed by the pad 15 of the underlayment 1. And the action of the air flow passing through the cloth 1, the material is sucked into the pad 15, and then passes through the hole 12 (see FIGS. 2 and 3) of the perforated plate 11 and the workbench 2
Is drawn into the internal space of the hose 22 and then collected in a collection container (not shown) laid on the hose 22.

During such stain removal work, the impact of the cleaning agent S sprayed from the gun 3 upon the cloth 5 is absorbed by the cushioning property of the pad 15 of the underlayment 1. Here, if the pad 15 is made of napped felt, the cushioning property due to napping is exerted in addition to the cushioning property of the felt itself, and therefore the shock absorbing action when the cleaning agent S collides with the cloth 5 is achieved. Further improve. Further, the pad 15 is used to inject the cleaning agent S and the suction mechanism
This helps prevent the cloth 5 from biting into the holes 12 ... of the perforated plate 11 due to the suction force. The impact absorbing action and the biting preventing action are surely exhibited not only when the cloth 5 is thick but also when the cloth 5 is thin, so that the spray pressure of the cleaning agent S by the gun 3 is increased ( For example, 60 kg / c
Even if the cleaning agent S is directly sprayed at a high pressure of m ² ) and at the same time the suction force is increased by using a compressor in the suction mechanism 4 to improve the efficiency of removing dirt and stains adhering to the cloth 5, There is no possibility that silk will be damaged due to holes or irregularities formed in 5. Further, by increasing the suction force of the suction mechanism 4, the cloth to which the cleaning agent S is attached dries quickly, which is very useful for preventing the occurrence of ring stain. The effect of suppressing ring stain is further promoted by the pad 15 quickly absorbing the cleaning agent adhering to the cloth 5.

It should be noted that as the cleaning agent, water-based or oil-based ones can be used properly according to the type of stains or stains, and the water-based alkaline cleaner described at the beginning is used for water-based or oil-based stains or stains. be able to. It is also possible to use water as a cleaning agent.

The workbench 2 may have an arm-like shape or a table-like shape.
The shape of the underlayment material 1 can also be determined arbitrarily. Furthermore, although the gun 3 has been described as the spraying mechanism of the cleaning agent S in the above-mentioned embodiment, this spraying mechanism may be one that can spray the cleaning agent, and the mode of spraying the cleaning agent is straight injection. Alternatively, it may be atomized injection.
