DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In the waste processing apparatus according to the present embodiment, as shown in FIG.
The crusher (crushing means) 11 is put into the crusher 11 as it is, and has a predetermined size (several cm square).
Crushed into pieces.

All the crushed pieces are sent to the first sorting means 12, where they are roughly separated into crushed pieces made of metal, rubber, resin or the like by means of wind separation, magnetic separation or the like.

The crushed pieces made of resin separated here are sent to a second separation means 13, where they are further separated into crushed pieces made of resin for each material.

This embodiment is characterized in that the crushed pieces made of resin for each material are separated.

As shown in FIG. 2, the second separation means 13 includes a hopper 13a for storing the resin crushed pieces separated by the first separation means 12, and the crushed pieces falling from the hopper 13a ( (Specific identification information is included as described below.) Is conveyed on the conveyor 13b, is identified by the identification means 13c, flows downstream, and is separated into resin-made crushed pieces by material by the separator 13d. . The sorting machine 13d includes a shooter S, which is swung by an actuator (not shown), whereby resin crushed pieces for each material are sorted and collected in a plurality of sorting boxes a to c.

Next, special identification information will be described.

The waste 10 crushed by the crusher 11, such as a printer, generally includes a plurality of resin parts made of different materials. Therefore, in order to identify a plurality of resin parts made of different materials for each material and to make them easier to separate, different identification information is added to each of the resin parts.

For example, when the waste 10 such as a printer includes three resin parts made of different materials, the first resin part has a crusher 11 as shown in FIG.
Of a size that remains in almost all the crushed pieces after crushing in
Identification information 15 represented by, for example, an identifiable number is added by printing. Although not shown in the drawing, identification information 15 of a size remaining on almost all crushed pieces after crushing and represented by, for example, identifiable numbers is added to the second resin part by printing. To the third resin component, identification information 15 represented by, for example, an identifiable number and having a size remaining in substantially all of the crushed pieces after crushing is added by printing.

The identification information 15 represented by the numeral
When crushed by the crusher 11, it must remain on almost all the crushed pieces.
It is added quite finely over the whole area of.

In this embodiment, as shown in FIG. 2, identification information 15 remains on almost all of the crushed pieces conveyed on the conveyor 13b, and this identification information 15 is used as identification means 13c by, for example, character recognition means. Identified by

When the number is identified by the identification means 13c, the crushed pieces are flowed downstream and then collected in the sorting box a. And if the numbers are identified,
The shooter S is swung to the intermediate position by the actuator, and the crushed pieces are collected downstream in the sorting box b after being flown downstream. If the number is identified, shooter S
Is oscillated to the uppermost position by the actuator, and the crushed pieces are flowed downstream, and then collected in the sorting box c via the fixed guide d.

The identification information 15 by printing can be added after the resin component 17 is molded. In this case, the identification information 15 may be printed on either the front surface or the back surface of the resin component 17. The identification information 15 may be a character, a symbol, a color, a pattern, or a barcode as long as it represents the material of the resin component.

When the identification information 15 is printed on the back surface of the resin component 17, even if the resin component 17 is incorporated into a printer or the like, the identification information 15 does not appear on the surface of the product. However, when printed on the surface, the identification information 15 appears on the product surface. In order to make the print identification information inconspicuous, the print identification information may be printed with ink that can be identified by irradiation with ultraviolet rays. In this case, even if the resin component 17 is incorporated in a printer or the like, if it is used in a normal state, the identification information 15 does not appear on the product surface unless ultraviolet rays are irradiated. However, in order to separate them, it is an essential condition that the identification unit 13c shown in FIG. 2 is a unit that can be identified by irradiation with ultraviolet rays.

As another embodiment, the identification information 15 can be added integrally when the resin component 17 is molded. In this case, for example, the identification information 15 is
The pattern may be a graining pattern formed on the front surface or the rear surface of 7 (unevenness added by a mold at the time of molding). This pattern can be changed in various ways, such as changing the shape of the unevenness and the roughness of the unevenness depending on the type of resin. Alternatively, the identification information 15 may be the resin color of the resin component 17.

In any case, when the resin component 17 is crushed by the crusher 11, the identification information 15 needs to remain on almost all crushed pieces.

In this embodiment, as shown in FIG. 2, the identification information 15 remains on almost all the crushed pieces conveyed on the conveyor 13b.
After being identified by c and flowing downstream, the crushed pieces can be sorted according to the material by the sorter 13d according to the identification result.

Regarding the step of adding the identification information 15 at the time of product molding or after the product molding, it is desirable to select and add a step which can be easily added depending on the type of the resin product 17.

As described above, in the present embodiment, the identifiable identification information 15 remaining on almost all of the crushed pieces after crushing is added to the resin component 17, so that even after the crushed pieces become crushed pieces, It is possible to identify which material the piece is made of resin.

Therefore, when recycling the waste 10 such as a printer, first, the waste 10 is crushed by the crusher 11.
