By rubbing a group of fragments of the synthetic resin material laminate put into the sieve member against the sieve member with the rubbing member, the cushion material of each fragment is passed through the sieve member while crushing, and the separation chamber is crushed. The first feature is to allow the device to be received.

According to this feature, not only does the rubbing member rotating with the rotary plate rub the debris group of the synthetic resin material laminate against the sieve member, but also the rotating airflow generated in the drum by the rotation of the rubbing member causes the debris to rotate. By rubbing the group against the sieve member, the relatively brittle cushion material of each fragment can be crushed and peeled from the skin material. At that time, since a certain gap is provided between the sieve member and the rubbing member, the relatively tough skin material of each fragment passes through the gap and escapes from pulverization, and remains in the sieve member.
On the other hand, the pulverized cushion material passes through the sieve member and is received in the separation chamber. Thus, the fragments of the synthetic resin material laminate are automatically and efficiently separated and separated into the skin material and the cushion material in the drum.

[0007] In addition, the present invention is characterized in that, in addition to the above-mentioned features, an edge protruding radially inward of the sieve member is formed around the mesh of the sieve member.

[0008] According to this feature, the cushioning material is crushed by the effect of the edge scratching the fragments.
Peeling is performed more effectively.

Further, in addition to the first or second feature, the present invention further comprises connecting a first discharge pipe for taking out the cushion material received therein to the separation chamber, and connecting the first discharge pipe to the separation chamber. A third feature is that a second discharge pipe for taking out the remaining epidermis to the outside is connected.

The third discharge port 35 ₃ is opened and closed by a shutter 45. The shutter 45 has a pivot 45 a rotatably supported by a bracket 46 provided on the drum 3. A lever 47 fixed to the pivot 45 a
The operating rod 48a of the air cylinder 48 provided below the drum 3 is connected. Therefore, the shutter 45 can be opened and closed by the operation of the air cylinder 48.

Next, the operation of this embodiment will be described.

[0025] In use of the separation fractionation apparatus 1 of the present invention, first, in a state of closing the third discharge port 35 ₃ by the shutter 45 to rotate the rotating plate 13 by actuating the electric motor 4, at the same time the first electric to operate the blower 38 _1. Rotating plate 2

_This produces an airflow that reaches _one .

In this state, when a certain amount of the laminate A fragments is thrown into the drum 3 from the hopper 28, the laminate A fragments that have entered the gap 25 are rubbed by the rubbing member 21 into the sieve member 9.
The relatively brittle cushion material b can be crushed and peeled off from the skin material a without substantially crushing the skin material a of each of the laminate A fragments.

In this case, a part or the entire periphery of the mesh 9a of the sieve member 9 is formed on the edge 9b protruding inward in the radial direction of the sieve member 9, so that the laminate of the edge 9b is formed. Due to the effect of scratching the A fragments, the cushion material b can be effectively crushed and peeled.

If the facing surface 21a of the rubbing member 21 with respect to the sieve member 9 is formed as a slope 21a 'having an upward slope in the rotation direction R of the rotating plate 20 as described above, the rubbing member 21 can be used. Sieve member 9 of laminate A fragment group
The effect of rubbing the cushion material b can be enhanced, and the cushion material b can be effectively crushed and peeled.

Further, the rubbing member 21 has an edge 26 formed at the front edge of the facing surface 21a in the rotation direction R, so that the edge 26 can be used to prevent the laminate A debris group during the rotation of the rubbing member 21. And the effect of crushing and separating the cushion material b can be enhanced.

Furthermore, the rotation of the rubbing member 21 also generates a rotating airflow in the drum 3, and the airflow rubs the group of pieces of the laminate A against the sieve member 9 without substantially crushing the skin material a. The cushion material b can be crushed and separated from the skin material a.

The cushion material b powder thus pulverized and peeled passes through the sieve member 9 and is received in the separation chamber 17, and then from the first and second discharge ports 35 ₁ and 35 ₂ to the first powder.

In the drum 3, the temperature rises due to the heat generated during the crushing and peeling of the cushion material b.
When the temperature exceeds 70 ° C., the temperature sensor 30 detects the temperature and sends a valve opening signal to the valve 33 of the water pipe 31 to open it, so that water from the cooling water supply source 32 is discharged from the water discharge nozzle 29. Through this process, an appropriate amount of water is discharged to the drum 3, and excessive evaporation of the water in the drum 3 is suppressed by the evaporation of the water, and the fusion of the laminate A fragments due to the excessive temperature increase can be avoided. Water vapor generated at this time is sent to the first cyclone 37 ₁ out of the cushion first and second outlet with material b powder 35 _1, 35 _2.

In the first cyclone 37 ₁ , the first discharge pipe 3
Slowing the air and water vapor from the ₆₁ released from the exhaust port 41 with the filter 40 to the outside, the cushion member b powder is stored in the first tank 43 ₁ is dropped from the outlet 42.

[0034] the first tank 43 ₁ if not cushion material b is falling, it is because it means that the cushion member b is separated from the skin material a, if it was confirmed that, operation of the first electric blower 38 ₁ Stop the air cylinder 48
By opening the shutter 45, i.e. the third to open the discharge port 35 _3, and to operate the second electric blower 38 _2. Then, the through the first exhaust pipe 36 ₂ From now drum within 3 2
An airflow toward cyclone 37 ₂ is generated, and sieve unit 8
Skin material a debris remaining within is transported by its air flow into the second cyclone 37 _2. In the second cyclone 37 _2, and decelerates the air from the first exhaust pipe 36 ₂ filter 4
Released from 0 with the exhaust port 41 to the outside, the skin material a debris is stored in ₂ second tank 43 is dropped from the outlet 42.

[0035] Note that the quantity of skin material a debris collected in the second tank 43 _2, since a relatively large cushioning material b debris which could not have passed through the sieve member 9 can often coexist, second applying those collected in the tank 43 ₂ further known air classifiers are effective on increasing the separation precision between the skin material a and the cushion member b.

FIG. 8 shows another embodiment of the separation / separation apparatus 1, in which a pair of left and right ring bodies 10a,
10 b is rotatably supported by a number of guide rollers 51 provided on the end plate 6 of the drum 3 and the door 7. An outer periphery of the right ring body 10b is formed in a ring gear 52, and a reverse rotation electric motor 50 is attached to the end plate 6, and a drive gear 53 fixed to a rotor shaft 50a meshes with the ring gear 52. Since other configurations are the same as those of the previous embodiment, the same reference numerals in the drawings denote the same parts as in the previous embodiment, and a description thereof will be omitted.

According to this embodiment, when the rotary plate 20 and the rubbing member 21 are rotated in the forward direction R by the electric motor 4, the sieve unit 8 is moved in the reverse direction by the reverse rotation electric motor 50.
By rotating in the direction, the relative rotation speed of the sieve unit 8 and the rubbing member 21 can be increased.

The present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the gist. For example, the opposing surface 21a of the rubbing member 21 with respect to the sieve member 9 may be formed as a rough surface or an uneven surface to enhance the effect of rubbing the laminate A fragment group on the sieve member 9.

[0039]

As described above, according to the first feature of the present invention, the rubbing member rotating with the rotary plate rubs the fragments of the synthetic resin material laminate, and is generated in the drum by the rotation of the rubbing member. The shards were rubbed against the sieve member with a rotating airflow.At this time, a constant gap was provided between the sieving member and the rubbing member. The material is crushed, peeled and passed through the sieve member, received in the separation chamber,
Thus, the synthetic resin material laminate can be automatically and efficiently separated and separated into a skin material and a cushion material, which can greatly contribute to cost reduction of waste material reuse.

According to the second feature of the present invention, since an edge protruding inward in the radial direction of the sieve member is formed on the periphery of the mesh of the sieve member, the edge has a scratching effect on each fragment. In addition, the cushion material can be more effectively crushed and peeled.

According to a third feature of the present invention, a first discharge pipe for taking out the cushioning material powder received therein is connected to the separation chamber, and a first discharge pipe is provided inside the sieve member. Since the second discharge pipe for taking out the separated skin fragments to the outside is connected, the skin material and the cushioning material separated and separated in the drum can be separately taken out by the first and second discharge pipes, respectively. It will be easier.
