BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, in the case of the conventional method for determining the material by infrared irradiation, it is difficult to make an accurate determination in the case of a case having unevenness or a slope on the surface. Focusing on the fact that reflected light cannot be obtained, the first feature is that a small plane for infrared irradiation used at the time of recycling, that is, an irradiation space is formed in the housing in advance. There is. The second feature is that the combination of the infrared irradiating device and the product automatic disassembling device enables the determination of the material and the automatic processing of the recycling work. Furthermore, if the desired reflected light cannot be obtained from the surface of the housing when determining the material by infrared irradiation, a small plane (irradiation space) for infrared irradiation is formed on the housing to accurately determine and recycle the material. The third feature is that it enables automatic processing of work.

Here, a method of determining a material by infrared irradiation will be briefly described. When a substance is irradiated with infrared rays, light having a predetermined wavelength is selectively absorbed according to the substance. Therefore, if you want to know the chemical structure of a substance, irradiate the substance (sample) with infrared rays to allow the substance to pass through,
An infrared absorption spectrum can be obtained by measuring the intensity of the transmitted light for each wavelength (infrared spectrophotometer). In this way, the infrared absorption spectrum differs depending on the type of substance, but this infrared absorption spectrum is not only the transmitted light,
The same applies to the reflected light. That is, even when the material is judged by the reflected light of infrared rays, it is known what kind of reflected light spectrum is obtained by irradiating the material with the infrared rays.

In the present invention, since the material is determined by the reflected light, the infrared absorption spectra of all the resin substances that may be used for the housing are stored in a table or the like. In addition, it is a part of the resin parts that make up the housing, and can be placed at any location that does not directly interfere with the use of the user.
In preparation for recycling at the time of disposal, a space (small plane) for irradiating infrared rays is provided in advance (claim 1
To claim 3). By providing such a small flat surface, the infrared rays can be accurately reflected in the desired direction (the position where the infrared detector is placed) even if the surface of the resin part has irregularities or slopes. You can

When disassembling for recycling,
Infrared rays are radiated to the infrared ray irradiation space provided in each resin component, and the resin material is determined by referring to the spectrum of the reflected light and the contents of the table (claim 4).
And the invention of claim 5). Furthermore, when one housing is composed of a plurality of resin parts, the material of each resin part is judged, and when the parts are of different materials, the resin parts are disassembled (claims 6 and 6). Invention of 7). Next, in the case of a conventional housing having no irradiation space or having unevenness or a slope on the surface, the irradiation space is formed by hot pressing or cutting to determine the material of the resin component (claim 8). Therefore, the invention of claim 10).

If so, disassemble each resin part. Therefore, in the disassembling step, the disassembling work of the resin parts made of the same material is the final step, and even if the resin parts are made of a large number of parts, if they are made of the same material, there is no need to disassemble them further. The above detection method will be described with reference to process drawings.

After that, the disassembled resin parts are sorted by material (the invention of claim 7). Note that these controls are also realized by so-called software program control.

Fifth Embodiment This fifth embodiment corresponds to the inventions of claims 8 to 10. The above-described first to fourth embodiments have been described on the assumption that an irradiation space (small plane) is provided in advance in the resin component forming the housing. However, the resin parts that make up the existing housing that has already been manufactured do not have such an irradiation space (small plane). In the fifth embodiment, even if the desired reflected light cannot be obtained from the surface of the housing when determining the material, the material can be accurately determined by the infrared irradiation, and the accurate material can be determined and recycled. It is characterized in that it enables automatic processing of work.

Also, to obtain the desired reflected light, heat press or cutting is performed to form the irradiation space (small plane),
The material of the resin component is judged using this irradiation space.

FIG. 8 is a diagram for explaining the principle of forming an irradiation space in the apparatus for detecting and disassembling the material of a resin casing by infrared rays according to the present invention. (1) is a state of irradiation space processing, and (2) is It is a figure which shows the irradiation state of infrared rays. In the figure, reference numeral 7 is a part of a housing having an inclined surface, 7a is an irradiation space forming region, 7b is a formed irradiation space, 8 is a heat press, and 9 is an infrared emitting portion.

In general, the existing housing does not have a space in the vertical direction with respect to the infrared rays IR to be irradiated, as shown in FIG. 7, so that the desired reflected light cannot be obtained. Alternatively, the housing has unevenness so that reflected light of desired intensity cannot be obtained. For such a chassis,
As shown by the broken line in FIG. 8 (1), an irradiation space perpendicular to the infrared IR to be irradiated is formed in a part 7 of the housing having an inclined surface (formation region 7a). Therefore, by applying a hot press 8, the irradiation space forming region 7a is melted to form a flat surface. The irradiation space may be formed by cutting a part of the housing 7 with a cutting tool. Thereafter, as shown in FIG. 8 (2), infrared rays are emitted from the infrared ray emitting section 9 to the formed irradiation space 7b to obtain desired reflected light.

6b is an irradiation space formed in the housing 6, 12 is a material detection / decomposition device, 12a is an infrared material detection unit, 12b is a decomposition means, and 12c is a space processing unit.

Material detecting / decomposing device 12 shown in FIG.
Is basically the same as the material detection / decomposition device 11 shown in FIGS. 6 and 7, but is different in that a space processing portion 12c is added. As the space processing unit 12c, for example, a turret head including a component discharge hand and two processing hands is used. As described above with reference to FIG. 7, when the irradiation space (small plane) is not provided in the housing 6 to be measured, the irradiation unit 6a of the housing 6 is used.
Infrared reflected by can not be detected. Therefore, in the material detection / decomposition device shown in FIG. 9, when the infrared light IR is applied to the housing 6 from the infrared material detection unit 12a and the reflected light is not obtained, the decomposing means 12b.
Instead of the above, the space processing portion 12c is used to form the irradiation space 6b by the method described in FIG. And
The formed irradiation space 6b is used to determine the material of the resin component. The above detection method will be described with a flow.

FIG. 10 is a flow chart showing the main processing flow when detecting the material in the method of detecting the material of the resin casing by infrared rays according to the present invention. In the reference numerals in the figure, S21 to S26 indicate steps.

In step S21, the infrared material detecting section 12
The resin part is irradiated with infrared rays from a to measure the reflection spectrum. In step S22, the closest reflection spectrum is found among the reflection spectra stored in advance, and the material is determined. In step S23, it is determined whether or not the material has been determined. When the material cannot be determined in step S23, the process proceeds to step S24, the irradiation space is formed in the resin component by the space processing portion 12c, and the process returns to step S21.

If the material can be determined by the determination in the previous step S23, the process proceeds to step S25. Step S
At 25, the resin part is disassembled by the disassembling means 12b. In this case, the space processing section 12c is moved and adjusted so that the disassembling means 12b can work. In step S26, the disassembled resin parts are transferred to the designated place for each judged material.

In this way, the material detection / decomposition device 12
By adding the space processing unit 12c, it is possible to quickly and accurately determine the material quality of a case that does not have an existing irradiation space or a case that has an uneven surface. In the case of the components described above, the disassembly work can be continued. Note that FIG.
The disassembling means 12b and the space processing part 12c are provided side by side, and when the infrared light material detection part 12a cannot detect the reflected light of the infrared IR, the disassembling means 12b and the space processing part 12c are switched and operated by the control signal. The case has been described (the inventions of claims 8 and 9). As described above, if the formation of the irradiation space and the irradiation of the infrared ray IR for material determination can be continuously performed, the work efficiency is improved. However, it is also possible to configure the space processing means and the disassembling means 12 by separate devices.

FIG. 11 is a block diagram showing an example of the embodiment of the space processing device used in the material detecting / decomposing device of the present invention. Reference numerals in the figure are the same as those in FIG. 7, 13 is a space processing device, and 13a is a space processing unit.

The space processing device 13 shown in FIG.
As described with reference to FIG. 7, the infrared material detection unit 11

After that, the material detection / decomposition device 11 shown in FIG. 7 determines the material and performs the necessary disassembly work. These controls are also realized by so-called software program control.
