[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for separating and separating a synthetic resin material laminate and a synthetic resin cushion material which are joined together to form a synthetic resin material laminate. In particular, a drum having an inlet on one side, an annular sieve member disposed in the drum, and a synthetic resin in the sieve member, which is charged into the interior through the inlet, Crushing means for applying a crushing force to a group of fragments of a synthetic resin material laminate composed of a skin material and a cushion material of a synthetic resin to crush the cushion material of each fragment into smaller pieces than the mesh of the sieve member to separate from the skin material; A separation chamber defined by an inner peripheral surface of the drum and an outer peripheral surface of the sieve member, for receiving the cushion material passing through the sieve member, and a cushion provided on the drum so as to open to the separation chamber Connected to the material outlet, A cushion material recovery means including a first blower for exerting a discharging force thereon, a shutter for opening and closing a skin material outlet opening to the sieve member, and a shutter connected to the skin material outlet for opening the shutter when the shutter is opened. And a skin material recovery means including a second blower which exerts a discharge force on a material discharge port.

[0002]

2. Description of the Related Art Such an apparatus for separating and separating a synthetic resin material laminate is already known as disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 8-258044.

In such an apparatus for separating and separating a synthetic resin material laminate, the cushion material pulverized in the drum and separated from the skin material is passed through a sieve member and received in the separation chamber, but immediately the first blower. The cushioning material is discharged from the cushioning material discharge port and collected by receiving the discharging force, so that the collection of the cushioning material ends almost simultaneously with the separation. On the other hand, the skin material remaining on the sieve member is recovered by opening the shutter and operating the second blower after confirming the separation of the cushion material. Therefore, if the collection of the skin material is delayed, one processing time from the input of the material to the drum to the collection is extended, and the processing cost is increased.

[0004]

However, in a conventional apparatus for separating and separating synthetic resin laminates, a skin material discharge port which is opened and closed by a shutter is provided on the side of the drum. When recovering the remaining skin material, the weight of the skin material cannot be used for the exhaust force from inside the sieve member.
It was difficult to shorten the collection time.

[0005] The present invention has been made in view of such circumstances, and after separating the synthetic resin laminate, the skin material remaining in the drum is removed from the skin material outlet through the skin material discharge port using their own weight. An object of the present invention is to provide an effective apparatus for separating and separating the synthetic resin material laminate, which can be quickly collected, shortened in one processing time and reduced in processing cost.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a drum having a charging port on one side, an annular sieve member provided in the drum, and Then, a crushing force is applied to a group of fragments of a synthetic resin material laminate composed of a skin material of synthetic resin and a cushion material of synthetic resin, which has been introduced into the interior through the above-mentioned inlet, to crush the cushion material of each fragment. Crushing means for separating the cushioning material from the skin material, an inner peripheral surface of the drum and an outer peripheral surface of the sieve member, and a separation chamber for receiving the cushion material passing through the sieve member, and an opening in the separation chamber. A cushion material recovery means including a first blower connected to a cushion material discharge port provided on the drum to exert a discharge force on the drum; a shutter for opening and closing a skin material discharge port opened to the sieve member; Connected to the skin material outlet And a skin material collecting means including a second blower that exerts a discharging force on the skin material discharge port when the shutter is opened, wherein the skin material discharge port is a sieve member. It is characterized in that it is provided below itself.

According to this feature, when the shutter is opened and the second blower is operated after the separation of the synthetic resin laminate, the skin material remaining in the drum is received by its own weight and from the second blower. Due to the discharge force, it quickly falls out of the drum from the skin material discharge port and is quickly collected.
As a result, it is possible to reduce the time required for collecting the skin material and, in turn, the time required for one treatment. Also, the shortening of the collection time of the skin material is to shorten the residence time of the skin material, which has become high during the separation, in the drum, thereby lowering the temperature in the drum.

The fourth discharge hole 35 ₄ 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.

In using the separation / separation apparatus 1 of the present invention, first, the electric pump 56 is operated to supply the laminate A fragments in the storage tank 30 to the quantitative tank 52. When the amount received in the fixed amount tank 52 reaches a specified amount, the fixed amount sensor 54
Generates a detection signal, stops the electric motor 4 and activates the vibration feeder 53, so that a predetermined amount of the laminate A debris in the fixed quantity tank 52 is automatically injected into the drum 3 through the conduit 51 and the hopper 29. You. The specified amount is shown in Fig. 6.
As shown in FIG. 6, the rotation of the rubbing member 21 is set so that the spatula 21b is appropriately buried in the laminate A fragment layer leveled on the inner peripheral surface of the sieve member 9.

Next, the fourth discharge port 35 _{4 is} operated by the shutter 45.
While it closed, and the member 21 rubbing through the rotary plate 13 by operating the electric motor 4 rotates in the direction of arrow R, operates the first electric blower 38 at _{a time.}

According to the rotation of the rubbing member 21, the radially outer surface f _{1 of} the spatula portion 21 b causes the laminate A debris group interposed between this and the inner peripheral surface of the sieve member 9 to the sieve member 9. At this time, the outer surface f ₁ is inclined radially outward toward the rear of the rotation direction R, and a gap 25 between the outer surface f ₁ and the inner peripheral surface of the sieve member 9 is rubbed. There because narrower as it goes in the direction of rotation R rear, outer side f ₁ with the rotation of the rubbing member 21 is to give the ironing to laminate a debris group, it is possible to increase the rubbing effect. As a result, the cushion material b of the laminate A fragment is immediately crushed and peeled off from the skin material a, but the skin material a is hardly crushed because the skin material a is relatively tough.

On the other hand, the radial inner surface f _{2 of} the spatula portion 21b
Is inclined inward in the radial direction toward the rear in the rotation direction R, so that the inner surface f ₂ scoops up the laminate A debris group with the rotation of the rubbing member 21, thereby effecting the debris group. Can be stirred. By the action of both side surfaces f ₁ and f ₂ of the rubbing member 21, it is possible to uniformly and efficiently separate the laminate A fragments into the skin material a and the cushion material b.

Moreover, since the edge 26 protruding inward of the sieve member 9 is formed on the entire periphery of the mesh 9a of the sieve member 9, the spatula portion 21b rubs the group of pieces of the laminate A against the sieve member 9. At this time, the edges 26 of the entire periphery of the mesh 9a scratch each fragment, so that the cushion material b can be more effectively crushed and peeled. In this case, in particular, the mesh 9a of the sieve member 9 is arranged in a zigzag shape along the rotation direction R of the rubbing member 21, and the edge interval S between the meshes 9a adjacent in the axial direction of the sieve member 9 is the mesh 9a. Since the inner diameter is set to be equal to or smaller than the inner diameter D, there is no area where the edge 26 of the mesh 9a does not exist when the inner peripheral surface of the sieve member 9 is viewed from the rotation direction R.
When the pieces of the laminate A are rubbed against the sieve member 9, each piece is scratched by the edge 26 of the mesh 9a without leakage, and the cushioning material b can be more effectively crushed and peeled.

The skin material a thus separated stays in the sieve member, and the cushion material b moves from the mesh 9a of the sieve member 9 to the separation chamber 17.

During this time, by the operation of the first electric blower 38 ₁ , the air flowing into the drum 3 from the outside air intake 32 passes through the sieve member 9 and the separation chamber 17, and then the first to third discharge ports 35 _1. by leaving the 35 _3, drum 3
The inside can always be kept in a state of cooling by ventilation. In particular, when the outside air intake 32 is provided near the center of the door 7, the air flowing into the outside air intake 32 is
Due to the rotation of the rubbing member 21, the inside of the drum 3 spreads radially, and the inside of the drum 3 can be satisfactorily cooled to every corner. Therefore, even if a large amount of heat is generated due to the crushing and peeling of the cushion material b, the excessive temperature rise in the drum 3 is suppressed, and the fusion of the laminate A fragments due to the excessive temperature rise is prevented. Therefore, the separation and separation apparatus 1 can be operated for a long time.

Further, the air having cooled the inside of the drum 3 exits the _{first to} third discharge ports 35 _{1 to} 35 ₃ together with the cushioning material b powder transferred to the separation chamber 17 and then the first discharge pipe 36. meet at _1, since being pumped into the first cyclone 37 _1, the first cyclone cushioning material b powder 37 ₁
Transfer to Eventually, only the skin material a remains in the sieve unit 8.

In the first cyclone 37 ₁ , the first discharge pipe 3

It is dropped from the stores to the first tank 43 _1.

First tank 43₁Cushion material b falls on
If it does not, the cushion material b is separated from the skin material a.
It means that it has been released.
Stop the dynamic motor 4 to stop the rotation of the rubbing member 21

Then, the shutter 45 is opened by the air cylinder 48, that is,

[0034] In this case, particularly, since the fourth outlet 35 ₄ is provided below the sieve member 9 itself, the skin material a debris accumulated in the sieve member 9 smoothly to the fourth outlet 35 ₄ outside It dropped, and since its fall to be accelerated in the air flow by the operation of the second electric blower 38 _2, it is possible to perform the transfer of the skin material a debris from the drum 3 to the second cyclone 37 ₂ quickly. Then, in the second cyclone 37 _2, and decelerates the air from the second discharge pipe 36 ₂ and discharged from the exhaust port 41 with the filter 40 to the outside, the second tank cover material a debris dropped from the discharge port 42 storing 43 _2.

As described above, the cushion material b can be effectively crushed and peeled, the cooling inside the drum 3 is good, and the fragments of the skin material a remaining in the drum 3 can be quickly discharged to the outside of the drum 3. Can greatly contribute to a reduction in one processing time from the time when the pieces of the laminate A are introduced into the drum 3 to the time when the pieces of the skin material a are discharged, and the continuous operation of the apparatus 1 becomes possible. Processing costs can be reduced. Further, shortening the collection time of the skin material a debris also means shortening the remaining time of the high temperature skin material a debris in the drum 3, thereby accelerating the temperature reduction in the drum 3. For long hours of continuous operation.

The present invention is not limited to the above embodiment, and various design changes can be made without departing from the scope of the gist.
