Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package of a moisture-curing caulking agent and a packaging apparatus for producing the package, and more specifically, a moisture used by being loaded in a jig called a caulking gun. The present invention relates to a curable caulking agent package and a packaging device for producing the same.

[0002]

2. Description of the Related Art Conventionally, a moisture-curing caulking agent is usually applied to a work surface such as a joint using a caulking gun, but in order to simplify the replenishing operation to the caulking gun,
It has been practiced to make the packaging form a hard plastic cylindrical container.

However, in response to the recent demand for resource saving, it has been attempted to supply a soft plastic package instead of disposing of a hard cylindrical container. Since the caulking agent is moisture-reactive, the packaging material forming the soft plastic packaging body is required to have moisture resistance and to some extent strength.
Further, in order to facilitate the discharge of the caulking agent by the caulking gun, and to reduce the discharge residual amount and the waste volume after use as much as possible, it is required to use a highly flexible packaging material. .

The main proposals relating to the technique of improving moistureproofness in a soft plastic package of a moisture-curing caulking agent are as follows. That is, Japanese Patent Publication Sho 59-334
No. 5, gazette discloses that a moisture-curable caulking agent is filled in a cylindrical container made of a flexible resin film, and the open end of the cylindrical container is ligated and sealed to form a package. A film or an aluminum vapor-deposited film is packaged, and a peripheral portion of the package film is hermetically sealed by bonding with heating or an adhesive, and a room temperature moisture-curable one-component sealant package for caulking gun is disclosed, This technology aims to prevent moisture, reduce the remaining discharge volume, and reduce the volume of waste. However, a concrete comparison or description of the effect of reducing the remaining discharge volume and volume of waste is required. There is no.

Further, in JP-A-61-227037, a cylindrical container made of a flexible aluminum laminate film obtained by laminating a polyethylene film, a polyamide film, an aluminum foil and a polypropylene film is used, and a room temperature moisture-curable single component is prepared. A system sealing agent is filled in a stream of dry nitrogen gas, and a room temperature moisture-curable one-component system sealing agent package for a caulking gun is disclosed in which the open ends of this cylindrical container are hermetically heat-sealed. Also in the technology, there is no description about specific comparison or effect on reduction of the discharge remaining amount and volume reduction of waste.

[0006]

DISCLOSURE OF THE INVENTION The inventors of the present invention have found that a cartridge type moisture-curable caulking agent package has a moisture-proof property required for caulking storage, reduces discharge residual amount, and reduces waste volume. As a result of earnestly studying volume reduction, the inventors have found that a specific packaging material, a laminated structure of the specific packaging material, and a packaging body obtained by the welding method thereof are effective, and completed the present invention.

[0007]

A moisture-curable caulking agent package according to claim 1 of the present invention is a moisture-curable caulking agent obtained by wrapping a moisture-curable caulking agent in a flexible packaging material. In the packaging body, the packaging material is formed by laminating a heat-sealable thermoplastic resin film on the front and back surfaces of the aluminum foil, and the packaging material is formed into a tubular shape, and both ends in the width direction thereof are Are laminated so that the front and back surfaces of the packaging material face each other, these overlapping portions are continuously welded, and the moisture-curing caulking agent is filled into the inside of the packaging material, and both ends in the length direction of the packaging material are striped. It is characterized by being ligated with a material.

Here, the aluminum foil has a thickness in the range of 7 μm to 15 μm, preferably 9 μm to 12
The one with μm is used. The range for this is
If the thickness is less than 7 μm, pinholes are likely to occur due to bending or ligation with a linear material, and moisture resistance remains a problem, and if it exceeds 15 μm, the flexibility required for volume reduction is secured. It is because it is not done.

As the heat-sealable thermoplastic resin film, for example, a single-layer film such as a high-density polyethylene film, an unstretched polypropylene film, an unstretched nylon film or a stretched polypropylene film is laminated with heat-sealable polypropylene. Examples thereof include a film, a film obtained by laminating a heat-sealable low molecular weight polyethylene terephthalate film on a polyethylene terephthalate film, and a multilayer film such as a two-layer film of a polyethylene film and an unstretched polypropylene film. Its thickness is in the range of 15 μm to 50 μm, preferably 15 μm to 40 μm. It is 15μ to stack on the front and back of aluminum foil in such a range.
If it is less than m, pinholes are likely to occur in the aluminum foil due to ligation with a linear material, and if it exceeds 50 μm, the flexibility of the packaging material cannot be secured.

In addition, the front and back surfaces of both ends of the packaging material are overlapped and welded to each other so that the number of layers laminated at both end portions of the packaging material is minimized to ensure flexibility at this joint portion. For facilitating volume reduction, the preferable overlapping width is set to 5 mm to 20 mm. This is 5
If it is less than mm, sufficient sealing strength cannot be secured, and if it exceeds 20 mm, the duplicated portion becomes large and it becomes difficult to secure flexibility, so the waste volume after use is reduced. This is because it cannot be reduced.

Further, the wire material is preferably made of aluminum wire in consideration of maintaining airtightness and handling at the time of ligation, and its wire diameter is determined by the shape and thickness of the packaging material to be applied. It is mainly 2.9mm-4.0mm
Used.

Further, in the moisture-curing caulking agent packaging device according to claim 3 of the present invention, a packaging material obtained by laminating heat-sealable thermoplastic resin films on the front and back surfaces of an aluminum foil is formed into a cylindrical shape. At the same time, both ends in the width direction of the former are overlapped so that these front and back surfaces face each other, welding means for continuously welding the overlapped portions, and moisture inside the cylindrical packaging material. A filling means for filling the curable caulking agent and the packaging material filled with the moisture curable caulking agent are squeezed from the outside to separate the moisture curable caulking agent inside the packaging material in the longitudinal direction of the packaging material. An ironing means and a ligating means for sealing the squeezed portion of the packaging material in which the moisture-curable caulking agent is separated by the ironing means, the filling means,
A filling nozzle that is inserted inside a cylindrically shaped packaging material, a filling pump that pressure-feeds the moisture-curing caulking agent to this filling nozzle, and a moisture-curing caulking agent that is stored and moisture-curing to the filling pump. And a surge tank that supplies a caulking agent
And a pressurizing means for reducing a negative pressure generated in the moisture-curable caulking agent stored therein.

[0013]

According to the package of the moisture-curable caulking agent according to claims 1 and 2 of the present invention, by using a packaging material in which a heat-sealable thermoplastic resin film is laminated on the front and back surfaces of an aluminum foil. , While ensuring sufficient flexibility of the packaging material, moisture resistance is secured by the aluminum foil, and further damage to this aluminum foil is
This is prevented by the thermoplastic resin film.

Further, by overlapping and welding both ends so that the front and back surfaces face each other, the internal pressure acting on the seal portion is in the shearing direction, and its strength is secured.
Furthermore, since the thermoplastic resin film can be heat-sealed, a cylindrical container can be easily obtained by sequentially heat-sealing the overlapping portions of the packaging material. Therefore, the moisture resistance and strength are secured by the package alone.

According to the moisture-curing caulking agent packaging device of the third aspect of the present invention, the packaging material is formed into a cylindrical shape by passing through the homer, and both ends thereof have front and back surfaces. They are overlapped in a state of being opposed to each other. When the packaging material is further moved from this state, the overlapping portion is heat-sealed by the welding means, so that the overlapping portion is firmly connected.

As a result, the moisture-curable caulking agent in the surge tank is sucked by the filling pump and sent under pressure to the filling nozzle, so that the moisture-curable caulking agent is filled inside the packaging material and then the packaging material is packed. Both ends of the material are ligated by ligating means to manufacture a package. When the moisture-curable caulking agent is filled, the internal pressure in the surge tank is reduced by the suction action of the filling pump, but the pressurizing means provided in the surge tank suppresses the reduction in the internal pressure. This prevents moisture from entering the moisture curable caulking agent in the surge tank.

[0017]

EXAMPLES Next, prior to the description of the examples of the moisture-curable caulking agent package according to claims 1 and 2 of the present invention, one example of the moisture-curable caulking agent packaging apparatus according to claim 3 will be described. Examples will be described.

In FIG. 1, reference numeral 1 denotes a moisture curable caulking agent packaging apparatus according to this embodiment (hereinafter abbreviated as a packaging apparatus). The packaging apparatus 1 is heat-sealed on the front and back surfaces of an aluminum foil. A packaging material 2 formed by laminating possible thermoplastic resin films is wound around, and the packaging material 2 drawn from the packaging material 2 is formed into a cylindrical shape, and the packaging material 2 is formed. Both ends 2a in the width direction of
2b and the homer 4 which is superposed so that these front and back surfaces face each other, and the superposed portion A of the packaging material 2 (see FIG. 2).
(Refer to FIG. 3), a welding means 5 for continuously welding, a filling means 6 for filling a caulking agent S inside the cylindrically-shaped packaging material 2, and a packaging material 2 filled with the caulking agent S from the outside. A ligature for sealing the squeezing means 7 for separating the caulking agent S therein in the lengthwise direction of the packaging material 2 by squeezing and the squeezed portion 2c of the packaging material 2 in which the caulking agent S is separated by the squeezing means 7. And means 8.

Next, these details will be explained.
The homer 4 has an inclined guide edge 4 as shown in FIG.
a first guide having a and guiding one end portion 2a of the laminated packaging material 2 to overlap the outer side of the cylindrically shaped packaging material 2 as shown in FIGS. 2 and 3. Piece 4
b and a second guide piece 4c that guides the other end 2b to the inside of the packaging material 2 are provided facing each other with a predetermined interval.

A hot plate for heat sealing is used as the welding means 5, and is provided immediately below the homer 4 so as to sandwich the respective end portions 2a and 2b superposed by the homer 4. .

Below the welding means 5, two sets of feed rollers 9 for feeding the welded and cylindrical packaging material 2 downward are provided. These feed rollers 9 are located below the tip of the filling nozzle 10 of the filling means 6 which will be described later, and the outer surface of the packaging material 2 is brought into pressure contact therewith, and the frictional force generated by this is utilized. The packaging material 2 is continuously moved downward.

The filling means 6 is, as shown in FIG. 1, a tank 11 provided separately from the packaging device for storing a caulking agent S, and is attached above the tank 11 to pressure-feed the caulking agent S. A pump 12, a surge tank 13 arranged at the uppermost part of the packaging device for storing the caulking agent S pumped by the pump 12, and a filling for pumping the caulking agent S supplied from the surge tank 13 to the filling nozzle 10. And the pump 14.

By the way, the surge tank 13 is provided with a vertically movable piston 15 therein, and a gas for lowering the piston 15, for example, an inert gas such as nitrogen is supplied to the surge tank 13. A working gas supply pipe 16 for supplying the gas is attached.

This is because the caulking agent S to be handled is moisture-curable, so that when the caulking agent S is fed under pressure by the filling pump 14, the portion of the surge tank 13 in which the caulking agent S is stored becomes a negative pressure and the outside air is discharged. This is a measure for preventing the suctioning of the caulking agent S, and the piston 15 shields the caulking agent S from the outside air.
By constantly pressurizing the caulking agent S by 5, the above-mentioned negative pressure is prevented from occurring.
The piston 15 and the working gas supply pipe 16 constitute the pressurizing means in this embodiment.

An elevating rod 17 projecting upward from the surge tank 13 is integrally attached to the piston 15, and an operating piece 18 is integrally provided on the elevating rod 17, and the surge tank 13 is further provided. At the top of

These limit switches 20 and 21 cooperate with the operating piece 18 that moves up and down as the piston 15 moves up and down to regulate the lowered position and the raised position of the piston 15.

The tip of the filling nozzle 10 is a region that comes into contact with the outside air, and the caulking agent immediately after being injected from the filling nozzle 10 into the cylindrical packaging material 2 comes into contact with the outside air and undergoes a curing reaction. It can happen. The entry of outside air into the tip of the filling nozzle 10 is normally prevented by the filling nozzle 10 or a size ring (a member provided at the tip of the filling nozzle 10 and defining the shape of the tubular packaging material, not shown). However, even when the humidity is high, the product may be adversely affected by moisture and the like that is brought along with the surface of the packaging material 2. Therefore, the filling nozzle 1
It is preferable that a purge pipe (not shown) that is open at the tip of 0 is provided along the filling nozzle 10 and that the tip is constantly purged with an inert gas such as nitrogen.

On the other hand, the squeezing means 7 is provided with a pair of squeezing rollers 22 provided with the wrapping material 2 in the shape of a cylinder sandwiched therebetween.
Is intermittently moved to a position where it is pressed and a position where it is separated from the packaging material 2, so that the caulking agent S filled between the packaging materials 2 is vertically separated in the packaging material 2. Has become.

The ligating means 8 is, as shown in FIG.
Two sets of four dies 23 and 24 arranged on both sides of the wrapping material 2 and at intervals in the longitudinal direction of the wrapping material 2 and between the upper and lower dies 23 and 24 are arranged. It is composed of a cutter 25.

Then, a wire material 26 for ligation (see FIG. 5) is supplied to both molds 23 and 24, and these molds 23 and 24 are supplied.
By sandwiching the squeezed portion 2c of the packaging material 2 while 24 is moved in the same direction in synchronization with the moving speed of the packaging material 2, the squeezed portions 2c are spaced apart in the longitudinal direction by 2
While squeezing at the location, it is ligated by the linear material 26, and after ligation, the squeezed portion 2c is cut by the cutter 25 in the middle between both linear materials 26.

In the packaging apparatus 1 of this embodiment having the above-mentioned structure, the packaging material 2 is continuously fed downward by the feed roller 9 so that the packaging material 2 is drawn into the homer 4 and the homer 4 is fed. 4 is formed into a cylindrical shape, and as shown in FIG. 3, both end portions 2a and 2b in the width direction thereof are overlapped with their front and back surfaces facing each other.
Are welded by the welding means 5 as shown in FIG.

When the above-mentioned caulking agent S is continuously filled and the remaining amount of the caulking agent S in the surge tank 13 reaches a predetermined amount, the caulking agent S is attached to the piston 15 which descends as the caulking agent S decreases. The operating piece 18 which is turned on turns on the lower limit switch 20, and the pump 12 is operated by the signal, whereby the caulking agent S in the tank 11 is transferred to the surge tank 13
Pumped to.

While the caulking agent S is being pressure-fed by the pump 12 as described above, the pressurized gas acts on the piston 15 from the working gas supply pipe 16. Therefore, a pressure adjusting valve 29 is provided in the working gas supply pipe 16 so that the pressure of the piston 15 is not excessively increased by the pressure feeding of the caulking agent S. As a result, the pumping of the caulking agent S is not hindered and the surge tank 13
Appropriate back pressure is applied to the caulking agent S pumped in, and even in this state, the caulking agent S is prevented from coming into contact with the outside air. The adjusting pressure of the pressure adjusting valve 29 operating in this way is preferably selected to be slightly higher than the pressure of the pressurized gas.

In such a pressure feeding operation of the caulking agent S from the tank 11 to the surge tank 13, the piston 15 is raised to a predetermined position, and the operating piece 18 turns on the upper limit switch 21. Stopped by.

The squeezed portion 2c is further ligated by the ligature means 8 with the filament material 26 at intervals in the length direction of the packaging material 2, and
The package 27 is manufactured by being cut by the cutter 25 at the intermediate position.

Therefore, according to the packaging apparatus 1 of this embodiment, from the molding of the packaging material 2 into the cylinder to the welding of both ends thereof,
Further, the steps of filling, ligating, and cutting the caulking agent S are continuously performed, and the discharged packaging body 27 is handled as a product as it is. The package 27 according to claim 1 is efficiently produced by keeping the pressurized state at all times to prevent the invasion of outside air, and the caulking agent S is surely prevented from being hardened to obtain a high-quality package 27. can get.
