The inside of the rear part of the first tube 18A is connected to the inside of the lower end of the supply hopper 14, and the plastic 16 discharged to the bottom of the supply hopper 14 is supplied into the inside of the rear part of the first tube 18A. A first screw 18B is provided coaxially within the first tube 18A, and the first screw 18B is rotated to transport the plastic 16 in the first tube 18A forward.
[0025] A second conveyor 20 (main screw) is provided below the first conveyor 18. A cylindrical second tube 20A is provided on the second conveyor 20, and the second tube 20A extends in the front-rear direction. The rear part of the second tube 20A is connected to the front part of the first tube 18A, and the plastic 16 transported to the front part of the first tube 18A is supplied to the rear part of the second tube 20A. A second screw 20B is provided coaxially within the second tube 20A, and the second screw 20B is rotated to transport the plastic 16 in the second tube 20A forward.
[0026] A melting mechanism 22 (volume reduction mechanism) is provided in front of the second conveyor 20. The melting mechanism 22 is provided with a rectangular melting tube 24, and the axial direction of the melting tube 24 is in the front-rear direction. The inside of the melting tube 24 is connected to the inside of the front end of the second tube 20A, and the plastic 16 conveyed forward from the inside of the second tube 20A passes forward through the inside of the melting tube 24. A plurality of rectangular melting plates 26 are fixed in the melting tube 24, and the melting plates 26 extend in the left-right direction. The plurality of melting plates 26 are arranged at intervals in the vertical direction, and the plurality of melting plates 26 divide the inside of the melting tube 24 in the vertical direction. The rear end of the uppermost melting plate 26 is connected to the upper surface of the inside of the melting tube 24, and the rear end of the lowermost melting plate 26 is connected to the lower surface of the inside of the melting tube 24. The multiple melting plates 26 are arranged in a direction toward the center in the vertical direction inside the melting cylinder 24 as they move forward, and the intervals between the melting plates 26 become smaller as they move forward. The melting plates 26 are electric heaters, and generate heat. Therefore, the melting plates 26 melt (thermally melt) the plastic 16 passing forward inside the melting cylinder 24 (between the melting plates 26), reducing its volume and compressing the plastic 16 in the vertical direction.
[0027] A conveying mechanism 28 is provided in front of the melting mechanism 22.
[0028] A molding mechanism 30 is provided at the rear of the conveying mechanism 28, and the molding mechanism 30 is provided with a molding plate 32. The molding plate 32 has a U-shaped cross section and is open to the upper side. The molding plate 32 is provided with a flat bottom wall, a left wall, and a right wall. The rear end of the molding plate 32 is connected to the front end of the melting tube 24, and the plastic 16 that has passed through the melting tube 24 is supplied to the molding plate 32. A predetermined number (two in this embodiment) of approximately cylindrical molding rolls 34 are supported on the upper side of the molding plate 32, and the predetermined number of molding rolls 34 are arranged in the front-rear direction with their axial direction in the left-right direction. The molding rolls 34 are brought close to the lower wall of the molding plate 32, and protrusions 34A are integrally provided on the peripheral surface, and the molding rolls 34 are rotated in a predetermined direction (the direction of the arrow A in FIG. 1). For this reason, the forming roll 34 compresses the plastic 16 supplied into the forming plate 32 in the vertical direction, roll-forming it into a rectangular plastic plate 16A (ingot), and conveys the plastic plate 16A forward. The temperature of the plastic 16 when the plastic plate 16A is being formed is around 100°C depending on the season and the ambient temperature, and the thickness of the formed plastic plate 16A is set to, for example, about 15 mm, which makes it easy to cool in the conveying mechanism 28 and easy to cut in the cutting mechanism 50 described below.
[0029] A forming blower 36 serving as a cooling device is provided above the predetermined number of forming rolls 34, and the forming blower 36 blows cooling air from above onto the plastic plate 16A to cool the plastic plate 16A. A heat exchange chamber 38 is provided below the forming plate 32, and the upper wall of the heat exchange chamber 38 is formed by the lower wall of the forming plate 32. A plurality of heat exchange plates 38A are integrally provided on the lower surface of the forming plate 32, and the heat exchange plates 38A extend downward in the heat exchange chamber 38. A forming plate blower 40 serving as a cooling device is connected to the heat exchange chamber 38, and the forming plate blower 40 blows cooling air into the heat exchange chamber 38, and the cooling air passes through the heat exchange chamber 38. Therefore, the forming plate 32 and the heat exchange plate 38A are cooled by the cooling air, and the plastic plate 16A is cooled.
[0030] The conveying mechanism 28 is provided with a cooling mechanism 42 (see FIG. 4) in front of the molding mechanism 30. The cooling mechanism 42 is provided with a cooling chamber 44 having a substantially rectangular parallelepiped shape, which extends in the front-rear direction and is open on the upper side. The lower wall of the cooling chamber 44 is formed of a plurality of cylindrical pipes 44A, which extend in the front-rear direction. The plurality of pipes 44A are arranged at intervals in the left-right direction, and the cooling chamber 44 is open on the lower side through the pipes 44A. The upper side of the lower wall of the cooling chamber 44 (the plurality of pipes 44A) is connected to the upper side of the lower wall of the molding plate 32, and the plastic plate 16A conveyed forward from above the lower wall of the molding plate 32 is conveyed forward on the lower wall of the cooling chamber 44.
[0031] The cooling mechanism 42 is provided with a plurality of cooling fans 46 (which may be cooling blowers) serving as coolers. Three cooling fans 46 are provided at intervals in the front-rear direction in the upper part of the cooling chamber 44, and two cooling fans 46 are provided at intervals in the front-rear direction in the lower part of the cooling chamber 44. The cooling fans 46 blow cooling air from above or below the plastic plate 16A to cool the plastic plate 16A.
[0032] A substantially cylindrical feed roll 48 (see FIG. 1) is supported at the front end of the cooling chamber 44, and the axial direction of the feed roll 48 is in the left-right direction. The feed roll 48 is disposed close to the bottom wall of the cooling chamber 44, and has a protrusion 48A integrally formed on its peripheral surface. The feed roll 48 is rotated in a predetermined direction (the direction of arrow A in FIG. 1) to transport the plastic plate 16A forward at a constant speed.
[0033] A cutting mechanism 50 (see FIGS. 5A and 5B) is provided in front of the transport mechanism 28 (cooling mechanism 42).
[0034] The cutting mechanism 50 is provided with a pair of disk-shaped crank plates 52 on the same axis, and the pair of crank plates 52 rotate together at a constant speed. The axial direction of the crank plates 52 is in the left-right direction, and the upper end of a crank rod 54 is rotatably connected to the periphery of the crank plate 52. A slider 56 having a substantially rectangular cylindrical shape is disposed between the lower ends of the pair of crank rods 54, and the lower end of the crank rod 54 is rotatably connected to the left wall or the right wall of the slider 56. The slider 56 is movable (slidable) in the vertical direction, and when the crank plates 52 are rotated, the slider 56 is reciprocated in the vertical direction via the crank rod 54.
[0035] A plurality of press blades 58 (see FIG. 8, and FIGS. 9A and 9B) each having a substantially rectangular columnar shape as a punching blade are fixed to the front side of the rear wall of the slider 56, and the press blades 58 are moved vertically together with the slider 56. The press blades 58 extend in the vertical direction, and extend below the slider 56. The multiple press blades 58 are arranged at intervals in the left-right direction, and the intervals (separation distances) between the press blades 58 in the left-right direction are set to be the same as the left-right dimensions of the press blades 58. The up-down positions of the multiple press blades 58 are alternately changed in the left-right direction between a high position and a low position, and at least a rear portion of the lower end surface of the press blade 58 is inclined downward as it approaches rearward.
[0036] A generally rectangular punching plate 60 (see FIG. 6) is fixed to the underside of the multiple press blades 58, and the punching plate 60 is arranged vertically in the up-down direction. A plurality of generally rectangular punching holes 60A are formed through the punching plate 60, and the punching holes 60A are arranged below the press blades 58. When the press blade 58 is moved downward, the press blade 58 is inserted into the punching hole 60A, and the rear surface, left surface, and right surface of the press blade 58 fit into the rear surface, left surface, and right surface of the punching hole 60A, respectively.
[0037] A cutting blade 62 (see FIGS. 7A and 7B) having a generally rectangular plate shape is fixed to the front side of the front wall of the slider 56, and the cutting blade 62 moves vertically together with the slider 56. The cutting blade 62 is disposed vertically in the front-to-rear direction and extends in the left-to-right direction, and extends below the slider 56. The front surface of the lower end of the cutting blade 62 is inclined toward the rear as it extends downward, and the lower end of the cutting blade 62 has a cross section in the shape of a right-angled triangle.
[0038] A rectangular fixed plate 64 (see Figs. 6 and 7(B)) is fixed to the underside of the cutting blade 62, in front of the punching plate 60, and the fixed plate 64 is disposed vertically in the up-down direction and extends in the left-right direction. In the punching plate 60, the front surface of the fixed plate 64 is disposed below the rear surface of the cutting blade 62, and when the cutting blade 62 is moved downward, the rear surface of the cutting blade 62 fits into the front surface of the fixed plate 64.
[0039] The upper sides of the punching plate 60 and the fixed plate 64 are connected to the upper side of the lower wall of the cooling chamber 44, and the plastic plate 16A transported from the cooling chamber 44 is transported forward at a constant speed over the punching plate 60 and the fixed plate 64 (see Figure 10 (A)).
[0040] Therefore, by moving the press blade 58 downward, the plastic plate 16A is punched by the press blade 58 and cut into granular (rectangular (particularly cubic)) plastic granules 16B (regrind, recycled pellets), and the plastic granules 16B fall below the punching plate 60 (see FIG. 10(B)). Moreover, by moving the press blade 58 downward at regular intervals, the plastic plate 16A is punched continuously in the front-rear direction by the press blade 58 and cut into columnar (long rectangular) plastic columns 16C between the press blades 58 (see FIG. 11(A)).
[0041] Furthermore, by moving the cutting blade 62 downward, the plastic column 16C is cut into plastic pellets 16B by the cutting blade 62, and the plastic pellets 16B are dropped below the fixed plate 64 (see FIG. 11(B)). Moreover, by moving the cutting blade 62 downward at regular intervals, the plastic column 16C is cut into plastic pellets 16B continuously in the front-rear direction by the cutting blade 62.
[0042] A cutting blower 66 (see FIG. 1) is provided above the punching plate 60 and the fixing plate 64 as a cooling device, and the cutting blower 66 blows cooling air from above onto the plastic plate 16A (including the plastic columns 16C) to cool the plastic plate 16A. This lowers the temperature of the plastic plate 16A to about 60°C, solidifying the plastic plate 16A so that the plastic plates 16A are not melted together by their own heat, and the plastic plate 16A is not completely hardened and has toughness so that the plastic plate 16A can be cut by the press blade 58 and the cutting blade 62.
[0043] A flat bar 68 (see FIG. 6) having a rectangular cross section and shaped like a rod is fixed as a restricting member near the upper side between the punching hole 60A of the punching plate 60 and the front surface of the punching plate 60, and the flat bar 68 extends in the left-right direction. When the press blade 58 and the cutting blade 62 cut the plastic plate 16A (including the plastic column 16C), even if the plastic plate 16A adheres (welds) to the press blade 58 or the cutting blade 62, the flat bar 68 restricts the upward movement of the plastic plate 16A together with the upward movement of the press blade 58 and the cutting blade 62.
[0044] A belt conveyor 70 (see FIG. 12) is provided below the punching plate 60 and the fixed plate 64, and the plastic granules 16B that drop below the punching plate 60 and the fixed plate 64 are placed on the belt conveyor 70. The belt conveyor 70 is then operated to transport the plastic granules 16B to the front side of the cutting mechanism 50 and discharge them.
[0045] A discharge tube 72 is provided below the front end of the belt conveyor 70. A part of the inside of the discharge tube 72 is open to the upper side, and the plastic granules 16B discharged from the belt conveyor 70 drop and are supplied into the discharge tube 72. One end of the discharge tube 72 is connected to a discharge fan 74 (turbo fan), and the other end of the discharge tube 72 is connected to a cyclone 76 (see FIG. 1). The plastic granules 16B are supplied from inside the discharge tube 72 to the cyclone 76 by the air blown from the discharge fan 74, and are dropped from the cyclone 76. A flexible container bag 78 (flexible container bag) is disposed below the cyclone 76 as a collecting section, and the plastic granules 16B dropped from the cyclone 76 are collected (filled) in the flexible container 78.
[0046] Next, the operation of this embodiment will be described.
[0047] In the plastic processing device 10 configured as above, the crushed plastic 16 is supplied from the supply hopper 14 of the supply mechanism 12 through the first conveyor 18 and the second conveyor 20 into the melting tube 24 of the melting mechanism 22, and melted by the melting plate 26 that generates heat in the melting tube 24. Then, in the forming mechanism 30 of the conveying mechanism 28, the plastic 16 is formed into a plastic plate 16A by the forming plate 32 and the forming roll 34, and the plastic plate 16A passes through the cooling mechanism 42 of the conveying mechanism 28. After that, in the cutting mechanism 50, the plastic plate 16A is cut into plastic granules 16B by the press blade 58 and the cutting blade 62, and the plastic granules 16B are automatically collected in the FIBC by the belt conveyor 70, the discharge tube 72, the discharge fan 74, and the cyclone 76. Then, the plastic granules 16B collected in the FIBC 78 are distributed as a raw material for recycling and are fed into the extruder.
[0048] In addition, the plastic plate 16A is cooled by the cooling air from the forming blower 36 and forming plate blower 40 of the forming mechanism 30, the cooling fan 46 of the cooling mechanism 42, and the cutting blower 66 of the cutting mechanism 50, and the temperature of the plastic plate 16A is reduced to about 60°C. As a result, the plastic granules 16B do not melt together due to their own heat, and the plastic granules 16B can be automatically collected in the flexible container 78 as described above, reducing the labor of workers and improving work efficiency. Moreover, since the plastic plate 16A is cooled by the cooling air and not by cooling water, the configuration of the plastic processing device 10 can be simplified.
[0049] Here, as described above, the plastic 16 melted in the melting mechanism 22 is molded into a plastic plate 16A in the molding mechanism 30. Therefore, the plastic plate 16A can be easily cooled to a tough state, and the plastic plate 16A can be easily cut into plastic pellets 16B by the press blade 58 and the cutting blade 62 of the cutting mechanism 50.
[0050] Moreover, the plastic plate 16A is cooled to a state where it is not completely hardened. This allows the power required for the press blade 58 and the cutting blade 62 to cut the plastic plate 16A into plastic granules 16B to be reduced, thereby reducing the energy cost for producing the plastic granules 16B.
[0051] Furthermore, the press blade 58 punches out the plastic plate 16A and cuts it into plastic pellets 16B. Therefore, the plastic plate 16A that is not completely hardened can be easily cut by the press blade 58 into plastic pellets 16B.
[0052] Moreover, at least the rear portion of the lower end surface of the press blade 58 is inclined downward toward the rear. This reduces the resistance exerted by the plastic plate 16A on the press blade 58 when the press blade 58 punches out the plastic plate 16A.
[0053] Furthermore, the press blade 58 cuts the plastic plate 16A continuously in the front-rear direction (conveyance direction) into a plurality of plastic pellets 16B. Therefore, the plastic plate 16A can be efficiently cut into the plastic pellets 16B.
[0054] Moreover, the multiple press blades 58 cut the plastic plate 16A in the left-right direction (transport width direction) into multiple plastic pellets 16B. This allows the plastic plate 16A to be efficiently cut into the plastic pellets 16B. Furthermore, the plastic plate 16A can be cut between the press blades 58 into plastic columns 16C.
[0055] In addition, after the press blades 58 cut the plastic plate 16A into the plastic columns 16C between the press blades 58, the cutting blade 62 cuts the plastic columns 16C into the plastic granules 16B. This increases the surface area of the plastic columns 16C, and the plastic columns 16C are easily cooled, so that the plastic columns 16C can be easily cut into the plastic granules 16B.
[0056] Furthermore, the cutting blade 62 cuts the plastic column 16C continuously in the front-rear direction (longitudinal direction) into a plurality of plastic pellets 16B. Therefore, the plastic column 16C can be efficiently cut into the plastic pellets 16B.
[0057] Moreover, the press blades 58 cut the plastic plate 16A in the left-right direction into the plastic columns 16C, and the cutting blade 62 cuts each of the plastic columns 16C into the plastic pellets 16B. This makes it possible to efficiently cut the plastic columns 16C into the plastic pellets 16B.
[0058] In this embodiment, the plastic plate 16A is cut into the plastic particles 16B between the plastic columns 16C. However, the plastic plate 16A does not have to be cut into the plastic particles 16B between the plastic columns 16C. [Explanation of symbols]
