Abstract

PROBLEM TO BE SOLVED: To perform a peeling work without leaning an excessive moisture or an interfacial active agent solution on a backing by a method wherein the surface of a layer to be peeled is covered, and pressurized steam is continuously sprayed all at once to a previously determined area of the surface of the layer to be peeled extending to the almost total surface. SOLUTION: Heated and pressurized steam which is fed from a pressurized steam feeding means is jetted to the surface of a face to be peeled of a wallpaper, from a jetting hole 13 which is opened toward a space in a flat box- shaped panel 11 which press-bonds the peripheral edges of a side wall, and the space in the panel 11 is filled with the heated and pressurized steam. The heated and pressurized steam which is filled, comes into contact with the surface to be peeled which has a temperature being much lower than the steam, and is condensed and returned to water, and imparts a proper moisture to the surface of the face to be peeled. The moisture still has a considerably high temperature, and a starch/adhesive layer which is inserted between the surface of the face to be peeled and its under layer is rapidly swollen and softened. By this method, the peeling and the removal of the face to be peeled from a backing become easier.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper stripping operation for easily and completely removing a backing paper and an adhesive layer remaining on a base when a decorative layer (vinyl layer) on the surface is peeled off during wallpaper replacement. The present invention relates to a wallpaper peeling device used at the time of (1).

[0002]

2. Description of the Related Art Conventionally, when replacing wallpaper, when removing the backing paper and the adhesive layer remaining on the surface by removing the wallpaper on the surface, water or warm water is applied to the surface of the layer to be removed. After waiting for swelling and softening of the layer to be peeled, a method of peeling and removing the layer to be peeled from the surface of the base using a spatula or the like has been adopted. In this method, not only a considerable amount of time is required for softening the layer to be peeled, but also there is a problem that surplus water or hot water drips to the floor surface, and the floor surface may be soiled. In addition, it took a considerable amount of time to dry the substrate after peeling, and it was not possible to immediately start the work of attaching new wallpaper.

[0003] When the decorative layer (vinyl layer) on the surface is peeled off, it is considerably difficult to completely remove the decorative layer (vinyl layer). Therefore, a new wallpaper may be applied without performing the complete peeling. In this case, a foundation is made of a gypsum board, a backing paper is pasted thereon, and a new wallpaper is pasted. At this time, the backing paper may not be sufficiently adhered. In some cases, the base material may be treated with a sealer and / or primer using a base material other than gypsum board. However, since the base material has a low water absorption capacity, it is lined with moisture that cannot be absorbed by the base material. As a result of stretching of the paper, there was a problem that blisters were generated on the wallpaper surface after reconstructing. If the old base is completely removed and a gypsum board base is created or a new gypsum board is applied, the problem of blistering can be solved for the time being. There was a drawback that required construction. In addition, in order to effectively remove the old backing paper remaining on the base, a surfactant solution is often applied to the surface of the layer to be peeled off. The surfactant remains on the lower ground, and the surfactant shifts to a higher concentration on the gypsum board side than on the backing paper side and penetrates, so that the surface of the gypsum board becomes weak or changes to an adhesive state. Sometimes they came.

[0004]

DISCLOSURE OF THE INVENTION In view of the above problems, the present invention does not require any application of water or a surfactant solution to soften a layer to be peeled, or minimizes the amount of water or a surfactant. Acquiring and providing a convenient peeling device when performing a peeling operation of a wallpaper that can continuously start a new wallpaper replacing operation immediately after peeling after performing a peeling operation after applying a solution. Make it an issue.

(Embodiment of the wallpaper peeling apparatus according to the first aspect of the invention) The means for coating the surface of the layer to be peeled is kept at an appropriate distance from the surface of the layer to be peeled, which is to be peeled. The peripheral portion can be in close contact with the surface of the layer to be peeled, and has a structure that covers the entire surface of the layer to be peeled. Since high-temperature pressurized steam is introduced into the inside of the structure, that is, a space formed between the inside of the structure and the surface of the layer to be peeled, when the wallpaper removing device is operated, the inside of the structure is heated with high-pressure pressurized steam. It must be made of a material that does not deform or break even when it comes into contact with

[0013] The pressurized steam spray means is located at an intermediate position between the coating means and the surface of the layer to be peeled, and is in communication with the pressurized steam supply means. The heated pressurized steam supplied from the pressurized steam supply unit is continuously and substantially continuously spread over substantially the entire surface over a predetermined area of the surface of the layer to be peeled defined by the range of the peripheral portion of the surface coating unit for the layer to be peeled. Must be able to squirt and spray. Therefore, in the structure of the pressurized steam spraying means, an ejection hole for ejecting heated pressurized steam in a space formed between the coating means and the surface of the layer to be peeled in the direction of the surface of the layer to be peeled, and the heated pressurized steam which has been ejected are provided. There is provided a structure for simultaneously and uniformly and continuously dispersing and distributing almost all over a predetermined area of the surface of the layer to be peeled.

[0014] Specific examples of the configuration include a relatively small number of heated and pressurized steam jet holes opened inside the coating means, a large number of heated and pressurized steam jet holes opened in the direction of the surface of the layer to be peeled, A combination of a relatively small number of orifices and baffles that diffuse heated and pressurized steam by colliding heated and pressurized steam provided in the ejection direction in the vicinity of the opening, or
A structure in which a relatively small number of orifices and a small number of orifices are closely spaced to cover the orifice portion, and the covering portion itself is provided with a plurality of orifices.

The above-mentioned pressurized steam supply means is required to be able to supply heated pressurized steam to the above-mentioned pressurized steam spray means. Basically, a tank capable of storing water, a heating facility capable of boiling water in the tank, a mechanism or structure for maintaining generated steam at a pressure equal to or higher than normal pressure in a sealed state, and a pressurized water for heating heated pressurized steam. A structure capable of being guided to the vapor spray means is provided.

(Embodiment relating to wallpaper stripping apparatus according to the second aspect of the invention) The invention relating to the wallpaper stripping apparatus according to the second aspect of the present invention is a particularly preferred pressurized steam among the wallpaper stripping apparatuses according to the first aspect of the invention. This is an invention for specifying a supply unit.

The structure of the pressurized steam supply means has a heating and pressurizing can body that seals steam generated by heating stored water and generates heated and pressurized steam. The heating and pressurizing can body needs to keep generating steam which has been heated and pressurized to 100 ° C. or more and normal pressure or more while maintaining a substantially uniform state for a predetermined period of time. It must have sufficient resistance to pressurized steam.

There is no particular limitation on the structure and form of the heating and pressurizing can body, and a heated and pressurized steam generated when a necessary amount of water is stored therein and the water is boiled can be sealed and held. Any structure and form can be adopted as long as it is possible. It should be noted that a water supply port and an outlet for generated heated and pressurized steam are required. The water supply port is sealed so that the heated and pressurized steam does not escape during the operation of the wallpaper stripping device.

When water is stored, usually, a large amount of water is stored in the structure of the pressurized steam supply means and reaches a considerable weight. It is desirable to attach gripping means, such as casters and handles. Also, considering the ease of handling at the construction site, the shape of the heating and pressurized can body may be formed in a rectangular shape with a small horizontal length compared to the height and height, so-called trunk type. Many.

The steam is placed on the bottom surface of the heating and pressurizing can or in contact with the water inside the can, heating the water to maintain a boiling state and heating and pressurizing the water to the above state. A heating member for generating the

Although the structure of the heating member is not particularly limited,
Generally, in consideration of the fact that the wallpaper peeling device is used at an indoor construction site, an electrothermal heating member which is easy to handle and has high safety is appropriate. For example, an electric heater buried in the bottom portion of the heating and pressing can body, which is located close to the bottom surface of the heating and pressing can body, one end of which is penetrated into the side wall of the heating and pressing can body, and the other end is fixed to the side wall. Rod-shaped electric heater or a thin-tube electric heater in which a heat-generating portion is accommodated in a thin metal tube bent and arranged in a planar shape.

As a pressure sensing member for sensing the pressure in the pressurized can indicated by the water vapor generated from the water contained in the pressurized can, a pressure gauge or the like indicating the pressure in the heated pressurized can is considered. Can be

However, the purpose of sensing the pressure is that the pressure of the heated and pressurized steam supplied to the pressurized steam spraying means is maintained within a predetermined pressure range, and the pressure of the heated and pressurized steam is always close to the temperature of the steam. Rather than displaying and recognizing the pressure inside the heating and pressurizing canister numerically, taking into account the relationship Based on the pressure and temperature in the can sensed by a temperature sensing member (e.g., a bimetallic temperature sensing member) installed on a diaphragm-type sensing member and a heating and pressing can body, preferably installed at multiple locations, The temperature and pressure of the heated and pressurized steam are maintained within a set value range by controlling the amount of electricity supplied to the electrothermal heating member via a computer. If we adopt a method that is more a practical convenient. Of course, even when this method is adopted, it does not prevent the provision of a pressure display device such as a pressure gauge.

As a structure of the pressure maintaining means capable of maintaining the pressure in the pressurized can within a predetermined pressure range, the opening and closing and the degree of opening and closing are determined based on the pressure sensed and detected by the pressure sensing member. Control / adjustment valve (discharge amount adjustment valve) provided at the outlet of the heating / pressurizing can body.

Further, assuming a case where the control / regulating valve provided at the outlet of the heating and pressurizing can body does not operate despite the abnormal increase in the pressure in the pressurizing can body, if necessary, A safety valve may be attached to the pressurized can body.

Further, at the outlet of the heating and pressurizing can body, a spout amount adjusting means capable of adjusting a supply amount (squirting amount) for supplying steam generated in the pressurizing can body to the pressurized steam spraying means, specifically, And a volume control valve.

The control / adjustment valve provided at the outlet of the heating / pressurizing can body and the supply amount adjustment valve can have the same function as the same valve. Of course, this does not prevent the individual valves from being provided with individual functions.

Further, the operation of the pressure control / regulation valve and / or the supply amount regulation valve has a close relationship with the state (temperature and pressure) of the heated and pressurized steam in the heated and pressurized can body. Accordingly, a diaphragm-type sensing member incorporated in-line or in a bypass at the outlet channel portion of the pressurized can body, and a temperature sensing member installed on the heating and pressurized can body, preferably installed at a plurality of locations (for example, a bimetallic temperature-sensing member) Based on the pressure and temperature inside the can sensed by
If necessary, by controlling the operation of the pressure control / regulating valve and / or the supply amount regulating valve via a computer, a method is adopted in which the supply amount (spouting amount) of the heated and pressurized steam can be adjusted. It is more practical and convenient. Of course, even when this method is adopted, the provision of the flow meter for displaying the supply amount (ejection amount) of the heated and pressurized steam is not prevented.

In addition, the steam supply / communication means, which communicates with the pressurized steam spraying means, is connected to the outlet flow path portion of the pressurized can body, specifically, the end thereof is communicated with the inlet of the pressurized steam spraying means. A tubular structure is required.

The present tubular structure is required to have a flexibility that allows it to move freely following the position of the pressurized steam spraying means and to be easily bent. In addition, the heated and pressurized steam is passed through the inside of the present tubular structure. However, when deformation such as a change in the tube diameter of the tubular structure occurs at that time, the flow of the heated and pressurized steam is simply inhibited. Not only that, there is a risk of the tubular structure deviating from the inlet portion of the pressurized steam spray means or damaging the tubular structure. Therefore, the material of the tubular structure has sufficient resistance to heated and pressurized steam. In addition, it is necessary to adopt a structure in which the tube diameter is hardly deformed. Further, the end of the tubular structure needs to be firmly connected to the inlet of the pressurized steam spraying means.

An example of such a tubular structure is a corrugated tube made of hard rubber in which a spiral metal wire is embedded inside the wall of the tube. Further, the periphery of the tubular structure may be covered with a suitable heat insulating material for the purpose of preventing heat loss from the circulating heated and pressurized steam and also preventing burns caused by contact of a construction worker.
