It is desirable that an industrial product using a resin material is recovered after being used in the market, and is recycled into the same resin material again.

[0003]

However, it is rare that an industrial product is composed of only a single material, and various metals, resins, and the like are selectively employed according to their respective functions. Normal. Therefore, in order to recycle the industrial products recovered from the market, it is necessary to disassemble the components at least once for each material and to treat the disassembled parts in an optimum manner for each material.

[0004] In the case of an industrial product in which dissimilar materials are inseparable, it is impossible to recycle the original materials. In such a case, for example, if the degree of mixing of multiple materials is high after crushing, it is landfilled or incinerated as dust, and even if the degree of mixing is small, the industrial value of the material is reduced and reused. It is hard to be done at present.

[0005] For example, when seals are attached to a resin component with an adhesive, it is necessary to separate a seal made of a different material and the adhesive from the resin component. However, this process,
That is, in order to perform the step of completely separating the resin and the adhesive, for example, as shown below, an operation requiring a great deal of manual labor is required.

FIG. 11 is a diagram showing a procedure for manually peeling off a seal from a resin component. A procedure for peeling off the seal will be described with reference to FIG.

First, as shown in FIG. 11A, the resin component 1 to which the seal 2 is attached is heated by the heating device 100 so that the adhesive 3 of the seal 2 can be easily peeled. Next, as shown in FIG. 11B, in a heated state, the seal 2 is grasped with tweezers 102 or the like, and separated so as to be peeled off from the resin component 1. Further, as shown in FIG. 11C, the adhesive 3a remaining on the resin component 1 is removed.
Wipe off with solvent 101 to remove completely.

[0008] From the above, in reality, resin parts to which seals are adhered with an adhesive as described above are often not subjected to troublesome separation work, and cannot be recycled.
Or, even if it can be recycled, it becomes a low-grade resin material mixed with different materials such as seals and adhesives, and its value is small.
