[0033]
Next, the operation of this embodiment will be described.
[0034]
First, a resin laminate such as an instrument panel of an automobile is crushed with a crusher (not shown) and then crushed with a crusher (not shown). The pulverized product e crushed by the pulverizer is separated into a flexible skin material a, a lightweight foam material b, and a hard core material c by a dry separator (not shown). At this time, since the skin material a is flexible, it tends to be crushed into a face plate shape. Further, since the core material c is hard, it tends to be crushed into a lump shape that approximates a spherical shape or a lump shape that approximates a columnar shape. In addition, the powder generated at the stage of the crusher, pulverizer or dry separator is collected separately.
[0035]
In this embodiment, the primary wind separation device 11 separates the powder f and the foam material b in the pulverized material e by the wind force with respect to the pulverized material e separated (separated) for each type by the dry separator. Perform wind separation process. For this purpose, the pulverized product e separated (separated) for each type by the dry separator is conveyed to the primary wind power separating device 11 through the cyclone 25, the primary tank 16, and the vibration feeder 28. In the primary wind power separating apparatus 11, the blower 30 is driven, and the pulverized material e input from the vibration feeder 28 is subjected to specific gravity selection using wind power. Thereby, the light powder f and the foam material b are sucked upward, and the remaining heavy pulverized material e1 is dropped. The light powder f and foam material b sucked upward are collected in a collection container 29 for foam material and the like. Note that the blower 30 sets the wind force in the primary wind separation process.
[0036]
Next, with respect to the pulverized product e1 that has passed through the primary wind separation process, a refining separation process is performed in which the endless rotating belt 12 inclined by the separation separation apparatus 13 rolls off and removes the lump-shaped core material c that approximates a sphere. Do. For this purpose, the pulverized material e1 that has passed through the primary wind power separating device 11 falls via the receiving member 31 and the vibration feeder 32 to the upstream side in the moving direction of the upper surface of the endless rotating belt 12 and to one end side in the width direction.
[0037]
In the separation / separation device 13, the endless rotating belt 12 is rotationally moved to select the shape of the pulverized material e <b> 1 that has passed through the primary wind separation process. Thereby, the lump-shaped core material c approximated to a spherical shape falls to one end in the width direction of the upper surface of the endless rotating belt 12 and falls to the receiving member 35, and the other pulverized material e2 remains on the upper surface of the endless rotating belt 12. It is transported downstream in the feed direction and falls to the receiving member 37. The lump-shaped core material c that has dropped onto the receiving member 35 is recovered in a recovery container 36 for the core material.
[0038]
Further, the secondary wind separation device 15 performs a secondary wind separation process for separating the large skin material a by the wind force between the transfer separation process and the vibration separation process described later. For this purpose, the crushed material e <b> 2 that has passed through the transfer separation device 13 is conveyed to the secondary wind separation device 15 via the suction loader 38, the secondary tank 17, and the vibration feeder 39. In the secondary wind separator 15, the blower 41 is driven so that the pulverized material e <b> 2 input from the vibration feeder 39 is subjected to specific gravity selection using wind power. As a result, the large skin material a is sucked upward, and the remaining heavy pulverized material e3 is dropped. The large skin material a sucked upward is collected in a collection container 40 for the skin material. Note that the blower 41 sets the wind force in the secondary wind separation process. Note that the wind force in the primary wind separation process is set to be relatively weak and the wind force in the secondary wind separation process is set to be relatively strong so that sorting can be performed according to the purpose.
[0039]
Then, after the separation and separation step and the secondary wind separation device 15, the vibration separation device 14 performs a vibration separation step of separating the skin material a and the remaining core material c by vibration. For this purpose, the crushed material e3 that has passed through the secondary wind separating device 15 passes through the receiving member 42 and the vibration feeder 43 to the upstream side in the feeding direction of the friction surface 44 of the vibration separating device 14 and to one end in the width direction. Fall. In the vibration separating device 14, the friction surface 44 is vibrated to select the shape of the pulverized material e <b> 3 that has passed through the secondary wind separation process. As a result, the lump-shaped core material c approximating a columnar shape falls to one end in the width direction of the friction surface 44 and falls to the receiving member 45, and the other skin material a is conveyed downstream in the feed direction of the friction surface 44. Then, it falls to the receiving member 46. The lump-shaped core material c that has dropped onto the receiving member 45 is recovered in the recovery container 36 for the core material.
[0040]
In this way, the pulverized material e is sorted in multiple stages. By sorting in multiple stages in this way, high sorting accuracy can be obtained. Moreover, since only the dry process which does not use water is sufficient, a highly accurate sorting can be performed with a simple configuration. The skin material “a”, the foam material “b”, and the core material “c” separated and collected for each type in this manner are reused as appropriate.
[0041]
Summarizing the above, according to this embodiment, separation of the core material c and the skin material a in the transfer separation process is performed by previously separating the excess powder f and foam material b in the primary wind separation process. Can be performed efficiently. In addition, by separating the extra powder f in the primary wind separation process in advance, the endless rotating belt 12 in the transfer separation process is prevented from being stained with the powder f.
[0042]
In addition, since the vibration separation step is provided after the reselection separation step, the remaining core material c that could not be separated in the reselection separation step can be separated by a vibration separation step with higher separation accuracy. In addition, since the vibration separation process is provided after the reselection separation process, the amount of processing in the vibration separation process, which takes time for separation, can be suppressed to a small amount, which is efficient.
[0043]
Further, since the secondary wind separation process is provided between the separation process and the vibration separation process, it is possible to separate the large skin material a in the secondary wind separation process. Efficiency can be improved by further reducing the amount of processing in the process.
[0044]
In addition, the powder f and the foam material b can be separated first by setting the wind force in the primary wind separation process relatively weak. Further, by setting the wind force in the secondary wind separation process relatively strongly, the large skin material a can be separated before being subjected to the vibration separation process. Thereby, the burden of a vibration isolation | separation process can be reduced and the efficiency of a vibration isolation | separation process can be raised.
[0045]
Here, the primary wind separation device 11 and the secondary wind separation device 15 and the tanks 16 and 17 for storing the pulverized material e to be supplied to these are disposed above the transfer separation device 13. Since the apparatus can be substantially configured within the range of the installation area of the separation apparatus 13, space efficiency can be improved.
[0046]

However, the embodiment is only an example of the present invention, and the present invention is not limited only to the configuration of the embodiment. Of course, changes in design and the like within a range not departing from the gist of the present invention are included in the present invention.
[0047]
【The invention's effect】
As described above, according to the invention of claim 1, the separation of the core material and the skin material in the reselection separation process is performed by previously separating excess powder and foam material in the primary wind separation process. Can be done efficiently. Further, by separating excess powder in advance in the primary wind separation process, it is possible to prevent the endless rotating belt in the transfer separation process from being contaminated with powder.
[0048]
In addition , since the vibration separation step is provided after the reselection separation step, the remaining core material that could not be separated in the reselection separation step can be separated by a vibration separation step with higher separation accuracy. In addition, since the vibration separation process is provided after the reselection separation process, the amount of processing in the vibration separation process, which takes time for separation, can be suppressed to a small amount, which is efficient.
[0049]
Furthermore , since a secondary wind separation process is provided between the separation process and the vibration separation process, a large skin material can be separated in the secondary wind separation process. The throughput can be further reduced to increase the efficiency.
According to the second aspect of the present invention, in the primary wind separation process, light powder and foam are sucked upward by the cylindrical primary wind separation device extending substantially in the vertical direction, and the remaining heavy pulverized material is dropped downward. In the secondary wind separation process, a large secondary skin material is sucked upward by the cylindrical secondary wind separation device extending in the vertical direction, and the remaining heavy crushed material is dropped downward. Can be separated.
[0050]
According to the invention of claim 3 , by setting the wind force in the primary wind separation process relatively weak, the powder and the foamed material can be separated first. Further, by setting the wind force in the secondary wind separation process relatively strong, a large skin material can be separated before being subjected to the vibration separation process. Thereby, the burden of a vibration isolation | separation process can be reduced and the efficiency of a vibration isolation | separation process can be raised.
[0051]
According to the fourth aspect of the present invention, the primary wind power separating device and the secondary wind power separating device, and the tank for storing the pulverized material to be supplied to them are disposed directly above or around the transfer separating device.
