Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for joining two objects with an adhesive in a state where the adhesive is impregnated with a gas-permeable and compressible impregnating material such as a sponge in advance. In order to intervene between objects,
The present invention relates to an adhesive impregnating device for impregnating an adhesive into a gas-permeable and compressible impregnated material.

[Conventional technology]

A method of fitting two objects through an air-permeable and compressible impregnated material impregnated with an adhesive is disclosed in, for example, Japanese Patent Application Laid-Open No. 56-100933.
JP, JP-A-56-100934 or JP-A-56-1009
It is disclosed in Japanese Patent Publication No. 40 and the like.

At the time of impregnation of the adhesive, a plurality of adhesives composed of a main agent, a curing agent, and, if necessary, a curing accelerator are charged into a separately prepared container, and the mixture is stirred and mixed. In addition, a method is employed in which a compressible material to be impregnated is charged and an adhesive is impregnated with the material to be impregnated.

[Problems to be solved by the invention]

However, in the above-mentioned conventional impregnation method, since operations such as stirring and mixing of the adhesive and impregnation of the adhesive into the material to be impregnated are performed in an open system and in a contact manner, the worker inhales the organic gas from the adhesive. There is an inconvenience in that the worker's skin or clothes are contaminated by the adhesive.

An object of the present invention is to provide an adhesive impregnating device that enables operations such as stirring and mixing of an adhesive and impregnation of an adhesive into a material to be impregnated in a closed system and in a non-contact manner.
It is to solve the above problems.

[Technical means and operation for solving the problem]

The above objects can be achieved by the present invention.

The adhesive impregnating device according to the first aspect of the present invention includes a flexible adhesive chamber filled with an adhesive, a flexible impregnated chamber filled with a breathable and compressible material to be impregnated, and a space between the adhesive chamber and the impregnating chamber. , A communication path closing means for closing the communication path, and a closing release means for releasing the communication path when used.

When using this adhesive impregnating tool, the adhesive passage closed between the adhesive chamber and the impregnation chamber by the communication passage closing means is opened by the closing release means, and then the adhesive chamber is squeezed or squeezed to remove the adhesive. The impregnated material is moved into the impregnation chamber, and then the impregnated chamber is thoroughly rubbed to uniformly impregnate the adhesive with the material to be impregnated.

The adhesive may be not only a single one-component adhesive but also an adhesive obtained by mixing a plurality of adhesives including a main agent, a curing agent, and, if necessary, a curing accelerator. The air-permeable and compressible impregnated material can be selected from, for example, sponges, felts, yarns, knitted fabrics, and other fiber bundles made of various materials. The material to be impregnated after impregnation may be taken out of the impregnation chamber after the impregnation chamber is appropriately opened by cutting or other known opening means.

Next, the adhesive impregnating device according to the second aspect of the present invention includes a plurality of flexible adhesive chambers in which a plurality of adhesives used together are individually sealed, and a plurality of flexible adhesive chambers in which a gas-permeable and compressible impregnated material is sealed. An impregnation chamber, a communication path provided between the required adhesive chambers for joining and mixing the respective adhesives, a communication path provided between the adhesive chamber having the mixed adhesive and the impregnation chamber, It is composed of communication path closing means for sealing each communication path and closing release means for releasing the closing of each communication path when used. When three or more types of adhesives are used in combination, the arrangement of the communication paths between the adhesive chambers and the communication paths between the adhesive chamber and the impregnation chamber are determined according to the mode of merging of the adhesives. You.

This adhesive impregnating tool is configured such that a plurality of adhesives composed of a main agent, a curing agent, and, if necessary, a curing accelerator and the like, which are separately disposed in each adhesive chamber, are combined and mixed at the time of use, and then moved into the impregnation chamber. It was made. That is, when using this adhesive impregnating tool, after opening each communication passage between the adhesive chambers, the respective adhesive chambers are squeezed or squeezed, and each adhesive is moved and joined into an appropriate adhesive chamber, Then, after the adhesive chamber is thoroughly rubbed and each adhesive is sufficiently stirred and mixed, as described above, the communication path between the adhesive chamber and the impregnation chamber is opened to move the adhesive into the impregnation chamber. .

Furthermore, the adhesive impregnating device according to the third aspect of the present invention includes a plurality of flexible adhesive chambers in which a plurality of adhesives to be used together are individually sealed, a flexible stirring chamber for mixing each adhesive, a gas permeable and compressible chamber. Flexible impregnation chamber in which the material to be impregnated is sealed, provided between the required adhesive chambers and the required adhesive chambers to join each adhesive to the stirring chamber, and between the required adhesive chambers as necessary. Communication path, a communication path provided between the stirring chamber and the impregnation chamber,
It is composed of communication path closing means for sealing each communication path and closing release means for releasing the closing of each communication path when used. The presence or absence and arrangement of communication paths between the adhesive chambers, the arrangement of communication paths between the adhesive chamber and the impregnation chamber, and the like are determined according to the manner in which the adhesives merge.

In this adhesive impregnating tool, a plurality of adhesives including a main agent, a curing agent, and, if necessary, a curing accelerator, which are separately arranged in each adhesive chamber, are combined and mixed in a stirring chamber, and then moved into the impregnation chamber. It is like that. That is, when using the adhesive impregnating tool, the communication path between each adhesive chamber to the stirring chamber,
And, if necessary, further opening the communication path between the adhesive chambers, then squeezing or squeezing each adhesive chamber to move and join each adhesive into the stirring chamber, and then rub the stirring chamber well to dissolve each adhesive. After sufficiently stirring and mixing, and subsequently opening the communication passage between the stirring chamber and the impregnation chamber, the stirring chamber is squeezed or squeezed to move the adhesive into the impregnation chamber.

In the present invention, since the adhesive chamber, the impregnating chamber and the stirring chamber all have flexibility, the above-described squeezing, ironing, or rubbing operations for moving the respective adhesives between the chambers, stirring and mixing and impregnating can be performed. It is possible. When the adhesive chamber, impregnation chamber and stirring chamber are made of a transparent material, the state of movement of the adhesive between the chambers, the state of stirring and mixing of the adhesives in the adhesive chamber and the stirring chamber, or the material to be impregnated. This is preferable because the state of impregnation of the adhesive and the like can be easily observed. In this case, the stirring and mixing state or the impregnation state of the adhesive can be determined by observing the color tone and the color unevenness of the adhesive and the material to be impregnated during the mixing. Completion of the stirring and mixing or impregnation may be determined by reaching a standard color tone specified in advance. Each of the adhesive and the material to be impregnated may be positively colored to facilitate observation of the color tone and the color unevenness.
